For a further understanding of the objects, construction, features and functions of the invention, reference should be made to the following detailed description of the preferred embodiments.
The invention provides a battery assembly which can be applied to an electric bicycle, but is not limited to the battery assembly. The battery assembly of the present invention may be applied to any device requiring a two-stage disassembly operation to provide a safe and convenient way of disassembling the battery assembly.
Fig. 1 is a schematic view of a battery assembly 1 according to an embodiment of the present invention. As shown in fig. 1, the battery assembly 1 includes a battery unit 10 and a battery holder 20. The battery unit 10 is detachably disposed on the battery holder 20. The battery unit 10 includes a battery 110, a first engaging portion 122, and a second engaging portion 124. The first engaging portion 122 and the second engaging portion 124 are disposed at the end 112 of the battery 110, and the second engaging portion 124 is movable relative to the end 112. The battery holder 20 includes a locking member 210. The locking member 210 can be selectively engaged with the first engaging portion 122 or the second engaging portion 124, and the locking member engages with the first engaging portion to position the battery cell at the first position, and the locking member engages with the second engaging portion to position the battery cell at the second position, so as to form a two-stage engaging mechanism. When the locking member 210 and the first locking portion 122 move relatively in the unlocking direction D1 (shown in fig. 3) to release the locking, the battery unit 10 moves from the first position to the second position where the locking member 210 and the second locking portion 124 are locked in the releasing direction D2 (shown in fig. 2), and the second locking portion 124 is allowed to move relative to the end 112 to release the locking with the locking member 210, so that the battery unit 10 is released from the battery holder 20.
Please refer to fig. 1 and 2 simultaneously, wherein fig. 2 is a partially enlarged exploded view of the battery cell 10 of fig. 1. Specifically, the battery 110 has two opposite ends 112 and 114 along the long axis, wherein the end 112 is adjacent to the battery holder 20, and the end 114 is far from the battery holder 20. The battery unit 10 includes a movable plate 120, the movable plate 120 is rotatably disposed at an end 112 of the battery 110, and the first engaging portion 122 and the second engaging portion 124 are disposed on the movable plate 120 along a disengaging direction D2 at intervals. In an embodiment, the first engaging portion 122 and the second engaging portion 124 are in the form of hooks, and when the battery unit 10 is positioned at the first position, and in the disengaging direction D2, the hook point of the second engaging portion 124 is preferably located outside the first engaging portion 122. In other words, the projection of the second engaging portion 124 along the disengaging direction D2 is at least partially outside the first engaging portion 122 (or the projection of the second engaging portion 124 is at least partially not overlapped with the first engaging portion 122), that is, the second engaging portion 124 protrudes toward the battery holder 20 more than the first engaging portion 122.
In one embodiment, the battery 110 is provided with a battery cover 130 at the end 112, and a pivoting mechanism (such as a shaft hole and a pivot) may be provided between the battery cover 130 and the movable plate 120, so that the movable plate 120 and the battery cover 130 are rotatably connected to be rotatable relative to the end 112. For example, the battery cover 130 has a shaft hole 132, the movable plate 120 has a corresponding shaft portion 128, and the shaft portion 128 is inserted into the shaft hole 132 so that the movable plate 120 can rotate relative to the battery cover 130 (or the end 112). In one embodiment, the shaft portion 128 may be integrally formed with the movable plate 120, and the shaft portion 128 is a protrusion extending laterally from the movable plate 120, but not limited thereto. In another embodiment, the shaft 128 and the movable plate 120 may be detachable components, for example, the movable plate 120 may have a through hole corresponding to the shaft hole 132, and the shaft 128 may be a shaft passing through the through hole and protruding from the movable plate 120 at two ends.
The movable plate 120 further has an operation portion 126, and the first engaging portion 122 is disposed between the second engaging portion 124 and the operation portion 126. Specifically, the second engaging portion 124, the first engaging portion 122, and the operating portion 126 are disposed in order along the disengaging direction D2 of the battery unit 10 from the battery holder 20, that is, the second engaging portion 124, the first engaging portion 122, and the operating portion 126 are located upstream, downstream, and midstream of the disengaging direction D2, respectively. In other words, when the disengagement direction D2 is downward, the second engaging portion 124, the first engaging portion 122, and the operating portion 126 are sequentially disposed from top to bottom. The operation portion 126 is forced to rotate the movable plate 120, for example, for being pushed by a user, so as to drive the movable plate 120 to rotate, and the second engaging portion 124 correspondingly moves away from the locking member 210 to release the engagement. In an embodiment, the operation portion 126 is a plate or a rod extending from the first engaging portion 122 in a direction away from the second engaging portion 124, and the operation portion 126 is preferably inclined toward the battery holder 10.
Furthermore, the battery unit 10 further includes an elastic member 140. The elastic member 140 is disposed between the movable plate 120 and the end 112 of the battery 110. The elastic member 140 provides a restoring force to keep the projection of the second engaging portion 124 along the disengaging direction D2 at least partially outside the first engaging portion 122. The elastic member 140 may be a compression or extension spring, and may be disposed corresponding to the second engaging portion 124 or the operating portion 126, so as to provide a corresponding restoring force to make the second engaging portion 124 keep protruding from the first engaging portion 122. In an embodiment, as shown in fig. 2, the elastic member 140 is disposed between the movable plate 120 and the end 112 of the battery 110 corresponding to the second engaging portion 124, and the elastic member 140 provides a restoring force to push the second engaging portion 124 toward the battery fixing base 20. For example, the elastic member 140 may be implemented as a compression spring, and two ends thereof respectively abut against the battery cover 130 and the movable plate 120. In an embodiment, as shown in fig. 2, a positioning hole (not shown) is formed on a side of the movable plate 120 opposite to the second engaging portion 124, i.e. a side facing the battery cover 130, for positioning the elastic member 140. That is, the elastic member 140 may be partially received in the positioning hole (not shown) and positioned between the battery cover 130 and the movable plate 120, but not limited thereto. The number of the positioning holes (not shown) may be one or more, so that one or more elastic bodies 140 are provided between the movable plate 120 and the end 112 of the battery 110. In another embodiment (not shown), the movable plate 120 or the battery cover 130 may have a positioning post, and the elastic member 140 may be sleeved on the positioning post to be positioned. As shown in fig. 5B, in another embodiment, the elastic member 140 is disposed between the movable plate 120 and the end portion 112 of the battery 110 corresponding to the operation portion 126, and the elastic member 140 may be implemented as an extension spring to provide a restoring force to pull the operation portion 126 toward the end portion 112 of the battery 110, so that the second engaging portion 124 is kept protruding from the first engaging portion 122 or is kept in an engaged state.
Please refer to fig. 1 and 3 at the same time, wherein fig. 3 is an exploded view of the battery holder 20 shown in fig. 1. In one embodiment, the battery holder 20 further includes a lock 220, a base 230, and an elastic member 240. The lock 220 is disposed on the battery holder 20 to couple with the locking member 210. Specifically, the lock 220 and the locking member 210 are disposed on opposite sides of the base 230, and the elastic member 240 is disposed between the lock 220 and the locking member 210. With the lock 220 locked and unlocked, the movement of the locking member 210 along the unlocking direction D1 can be restricted or allowed. For example, when the lock 220 is in the locked state, the locking member 210 and the first engaging portion 122 are restricted from moving relatively along the unlocking direction D1 to keep engaged; when the lock 220 is in the unlocked state, the locking member 210 is driven to move along the unlocking direction D1, so as to release the locking member 210 from locking with the first locking portion 122.
The locking piece 210 has a locking portion 212, and the locking portion 212 protrudes outward, that is, in the direction of the battery cell 10. The locking portion 212 may be in the form of a hook having a shape corresponding to the first engaging portion 122 and the second engaging portion 124, so as to be engaged with the first engaging portion 122 or the second engaging portion 124. The locking member 210 further has a coupling hole 214 for coupling with the lock 220. In an embodiment, the coupling hole 214 has a first hole portion 214a and a second hole portion 214b that are in communication with each other, and the aperture of the first hole portion 214a is larger than the aperture of the second hole portion 214b, so as to form the gourd-shaped coupling hole 214.
Lock 220 includes a lock body 222 and a drive shaft 224. The drive shaft 224 is coupled to the lock body 222, and the drive shaft 224 is extended or retracted relative to the lock body 222, i.e., in the unlocking direction D1, corresponding to the locking and unlocking of the lock body 222. For example, the lock body 222 may be a key lock or a combination lock, and may be in a locked or unlocked state by a key or a combination setting. When lock body 222 is in the locked state, drive shaft 224 is in an extended state relative to lock body 222. When lock body 222 is in the unlocked state, drive shaft 224 is in a retracted state relative to lock body 222. That is, the length of extension of drive shaft 224 relative to lock body 222 is greater than the length of extension of drive shaft 224 relative to lock body 222 in the retracted state. The drive shaft 224 includes a neck section 226 and a head section 228 along a long axis direction, and a width (or radial diameter) of the neck section 226 perpendicular to the long axis direction (or telescoping direction) is smaller than a width (or radial diameter) of the head section 228 perpendicular to the long axis direction (or telescoping direction). That is, neck section 226 is retracted relative to head section 228.
The base 230 is preferably in the form of a hollow housing to allow the latch 210 to move within the base 230 relative to the base 230. In one embodiment, the base 230 includes a first side plate 232, a base 234, and a second side plate 236. The base 234 is a frame having a receiving space 2342 therein, and the first side plate 232 and the second side plate 236 are disposed on opposite sides of the base 234 with respect to the receiving space 2342, respectively, so as to form a housing having the receiving space 2342 therein. The first side plate 232 and the second side plate 236 may be connected to the base 234 by locking, fastening, adhering, welding, etc., but not limited thereto. In another embodiment, the first side plate 232 and/or the second side plate 236 may be integrally formed with the base 234 to form a housing having a receiving space 2342 therein. The first side plate 232 is adjacent to the lock 220 and the second side plate 236 is adjacent to the catch 210. The first side plate 232 has a through hole 2322, and the second side plate 236 has an opening 2364, and the through hole 2322 and the opening 2364 are in communication with the accommodating space 2342. The through hole 2322 corresponds in size to the drive shaft 224 to allow the drive shaft 224 to pass through, and the opening 2364 corresponds in size to the catch 210 to allow the catch 212 to protrude.
The lock 220 is disposed outside the first side plate 232, and the driving shaft 224 passes through the through hole 2322 and the accommodating space 2342. The elastic element 240 is disposed between the first side plate 232 and the locking member 212, and is sleeved on the driving shaft 224. The aperture of the first bore portion 214a corresponds to the head section 228 of the drive shaft 224 and the aperture of the second bore portion 214b corresponds to the neck section 226 to allow the drive shaft 224 to pass from the first bore portion 214a through the coupling bore 214 such that the head section 228 is located on a side of the catch 210 adjacent the second side plate 236 and the neck section 226 is located in the first bore portion 214a of the coupling bore 214. Thus, during assembly, the driving shaft 224 can be moved toward the second hole 214b to engage the neck portion 226 with the second hole 214b, so that the driving shaft 224 is firmly coupled to the locking member 210 to form a linkage mechanism, and the locking portion 212 is exposed from the opening 2364.
Referring to fig. 4A and 4B, fig. 4A and 4B are schematic cross-sectional views of the battery holder 20 to position the battery unit 10 at the first position and the second position, respectively. As shown in fig. 4A, when the locking member 210 is locked with the first locking portion 122, the battery holder 20 positions the battery unit 10 at the first position. The first position is a position where the battery unit 10 is coupled with the battery holder 20 and locked. For example, in the first position, lock 220 may be locked or unlocked. When the lock 220 is in the locked state, the driving shaft 224 is in an extended state and cannot move relative to the lock body 222, so that the locking member 210 and the first locking portion 122 cannot move relative to each other in the unlocking direction D1 to maintain the locked state, and the battery unit 10 is locked to the battery fixing base 20. In this embodiment, the base 230 may have a stop surface 2362. When the battery unit 10 is positioned at the first position, the blocking surface 2362 corresponds to the second engaging portion 124, so as to further limit the movement of the movable plate 120, so as to strengthen the engagement between the blocking member 210 and the first engaging portion 122.
As shown in fig. 4B, when the lock 220 is changed from the locked state to the unlocked state, the driving shaft 224 moves (i.e. retracts) toward the lock body 222 to drive the locking member 210 to move away from the first engaging portion 122 along the unlocking direction D1 to release the engaged state, and the battery unit 10 moves from the first position to the second position where the locking member 210 is engaged with the second engaging portion 124 along the disengaging direction D2. For example, when the locking member 210 is disengaged from the first locking portion 122, the battery unit 10 can move downward relative to the battery holder 20 by gravity, and is locked and positioned at the second position by the second locking portion 124 and the locking member 210. When the battery unit 10 is positioned at the second position, the movable plate 120 is allowed to move relative to the end 112 to release the engagement between the second engaging portion 124 and the locking member 210, so that the battery unit 10 can move relative to the battery fixing base 20 again along the releasing direction D2 to release from the battery fixing base 20. In this embodiment, the unlocking direction D1 is perpendicular to the disengaging direction D2, i.e. the unlocking direction D1 and the disengaging direction D2 are orthogonal, but not limited thereto. In other embodiments, the angle between the unlocking direction D1 and the disengaging direction D2 may be greater than or less than 90 degrees.
Fig. 5A is a schematic partial cross-sectional view of a battery assembly 1 according to another embodiment of the present invention. In this embodiment, the stop surface 2362 may alternatively be provided on the locking member 210. As shown in fig. 5A, the locking member 210 has a locking portion 212 and a locking surface 2362, and the locking portion 212 and the locking surface 2362 are respectively located at opposite ends of the locking member 210. Specifically, the locking portion 212 and the stopper surface 2362 are provided along the disengaging direction of the battery cell 10, and the stopper surface 2362 is located upstream and the locking portion 212 is located downstream. In the embodiment of fig. 4A and fig. 5A, the blocking surface 2362 corresponds to the second engaging portion 124 in the form of a hook, and may be an inclined surface inclined from top to bottom toward the inner side of the base 230, but is not limited thereto. In other embodiments, the stop surface 2362 may be a vertical surface. In the embodiment where the battery holder 20 has the blocking surface 2362 and the battery unit 10 has the elastic member 140, when the battery unit 10 is positioned at the first position, the blocking surface 2362 may press against the movable plate 120 (or the second engaging portion 124) and the elastic member 140, so that the second engaging portion 124 does not necessarily protrude toward the locking member 210 compared to the first engaging portion 122. After the locking member 210 and the first locking portion 122 are released from the locking surface 2362, the elastic member 140 can provide a restoring force to move the second locking portion 124 towards the locking member 210, so as to form a protruding state or a protruding state more towards the locking member 210 than the first locking portion 122, and further can be locked with the locking member 210.
Preferably, a guiding structure is provided between the battery unit 10 and the battery holder 20 to guide the movement of the battery unit 10 relative to the battery holder 20. Fig. 6A and 6B are partial schematic views of a battery assembly 1 according to various embodiments of the present invention. As shown in fig. 6A, the end 112 of the battery 110 has a guide slot 134, and the base 230 moves relatively along the guide slot 134 to guide the movement of the battery unit 10 relative to the battery holder 20. For example, the battery cover 130 may be formed with guide grooves 134 on both sides of the movable plate 120 by surface structure design, and the extending direction of the guide grooves 134 is parallel to the disengaging direction D2 of the battery unit 10. Corresponding to the design of the guide groove 134, the base 230 may form guide blocks 2366 on both sides of the second side plate 236. When the battery unit 10 moves relative to the battery holder 20, the guide block 2366 moves relatively in the guide groove 134 to achieve the guiding function. The guiding structure between the battery unit 10 and the battery holder 20 is not limited to the guide groove and the guide block, and may be guided by the guide wall and the guide surface. In another aspect, the battery unit 10 may have a recess (e.g., 134) at the end 112, and the outer wall 2367 of the base 230 moves along the side wall 135 of the recess to guide the movement of the battery unit 10 relative to the battery holder 20. For example, the battery cover 130 may design the recess according to the width of the second side plate 236, such that the two side walls 135 of the recess parallel to the detachment direction of the battery unit 10 form a guiding surface corresponding to the outer wall 2367 of the second side plate 236. Accordingly, when the battery unit 10 moves relative to the battery holder 20, the outer wall 2367 of the base 230 moves along the side wall 135 of the recess portion, so as to achieve the guiding function.
As shown in fig. 6B, the guiding surface 2368 of the base 230 may be formed on the inner surface of the side wall of the second side plate 236, and the guiding wall 136 of the battery cell 10 may be a protruding side wall of the battery cover 130' corresponding to the guiding surface 2368. In this embodiment, the distance between the guide walls 136 is equal to or slightly less than the distance between the guide surfaces 2368. Thus, when the battery unit 10 moves relative to the battery holder 20, the guiding wall 136 moves along the guiding surface 2368 to achieve the guiding effect.
An operation of the battery assembly 1 according to an embodiment of the present invention is described with reference to fig. 7A to 7E. As shown in fig. 7A, the battery unit 10 is completely mounted on the battery holder 20, and the movement of the locking member 210 is limited by the lock of the lock 220, so that the locking portion 212 is kept engaged with the first engaging portion 122 of the battery unit 10, so as to limit the movement of the battery unit 10 relative to the battery holder 20 and to be positioned at the first position, i.e. the undetachable position.
As shown in fig. 7B, the lock 220 is changed from the locked state to the unlocked state, and the driving shaft 224 retracts to drive the locking member 210 to move away from the first engaging portion 122 toward the accommodating space 2342, so as to release the engagement. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move relative to the battery holder 20, for example, downward by gravity. Since the second engaging portion 124 protrudes toward the engaging member 210 compared to the first engaging portion 122, the battery unit 10 moves relative to the battery holder 20 to the second position where the engaging portion 212 engages with the second engaging portion 124, as shown in fig. 7C. That is, when the lock 220 is changed from the locked state to the unlocked state, the engaging member 210 is driven to move along the unlocking direction D1 so that the engaging portion 212 is far away from the first engaging portion 122, but the engaging portion 212 of the engaging member 210 is still maintained on the moving path of the second engaging portion 124 along the disengaging direction D2, so that when the battery unit 10 moves along the disengaging direction D2, the engaging portion 212 interferes (or engages) with the second engaging portion 124, and the battery unit 10 stops moving and is positioned at the second position.
As shown in fig. 7C, when the battery unit 10 is positioned at the second position, since the second engaging portion 124 can move relative to the end 112 of the battery 110, the user can apply an external force F to the operating portion 126, for example, push the operating portion 126 toward the battery holder 20, so that the movable plate 120 rotates about the shaft portion 128 as a rotation center along the clockwise direction R, and further drives the second engaging portion 124 to rotate away from the engaging portion 212, as shown in fig. 7D. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move again along the disengagement direction D2 relative to the battery holder 20, for example, downward by gravity, so as to be detached from the battery holder 20, as shown in fig. 7E.
Further, by setting the lock 220 in the unlocked state and reversing the operation in the sequence shown in fig. 7A to 7E, the battery unit 10 can be mounted to the battery holder 20. In the process of installing the battery unit 10 on the battery holder 20, after the external force F is released, the elastic member 140 (not shown herein) can provide a restoring force to the movable plate 120, so that the movable plate 120 rotates reversely to move the second engaging portion 124 towards the battery holder 20. Alternatively, by the hook slope design of the second engaging portion 124 and the locking portion 212, the battery unit 10 can be directly pushed in the mounting direction (i.e. the opposite direction to the releasing direction D2) without applying an external force F to the operating portion 126, so that the battery unit 10 is mounted on the battery holder 20.
Fig. 8A to 8E are schematic views illustrating operations of the battery assembly 1 according to another embodiment of the present invention. As shown in fig. 8A, in this embodiment, the operation portion 126 is rotatably coupled to the movable plate 120 'adjacent to one end of the first engaging portion 122, and the operation portion 126 is forced (e.g. pushed by a user) to drive the movable plate 120' to rotate, so as to release the engagement between the second engaging portion 124 and the locking member 120. Specifically, the operation portion 126 and the movable plate 120' are two members coupled to each other. The movable plate 120 'has a first engaging portion 122 and a second engaging portion 124 disposed at opposite ends at intervals, and the operating portion 126 is rotatably coupled to the movable plate 120', such that the second engaging portion 124, the first engaging portion 122 and the operating portion 126 have a configuration similar to the foregoing embodiments. In this embodiment, the operation portion 126 may have a bent shape such as an arcuate shape. The operation portion 126 is rotatably coupled to the battery cover 130 (or the end portion 112) at a bending point through a rotation shaft 160, and one end of the operation portion 126 is rotatably coupled to the movable plate 120 'through a rotation shaft 150, so that the movable plate 120' is driven to rotate when the operation portion 126 rotates relative to the end portion 112.
The operation of the operation portion 126 will be described with reference to fig. 8A to 8E, and the rest of the operation of the battery assembly 1 will be described with reference to the foregoing embodiments. As shown in fig. 8A, the battery unit 10 is completely mounted on the battery holder 20, and the movement of the locking member 210 is limited by the lock of the lock 220, so that the locking portion 212 is kept engaged with the first engaging portion 122 of the battery unit 10, so as to limit the movement of the battery unit 10 relative to the battery holder 20 and to be positioned at the first position, i.e. the undetachable position. At this time, the operation portion 126 is bent toward the battery holder 20, i.e., the free end of the operation portion 126 is closer to the battery holder 20 than the rotation shaft 160 thereof.
As shown in fig. 8B, the lock 220 is changed from the locked state to the unlocked state, and the driving shaft 224 retracts to drive the locking member 210 to move away from the first engaging portion 122 in the unlocking direction D1 toward the accommodating space 2342, so as to release the engagement. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move in the disengaging direction D2 relative to the battery holder 20, for example, downward by gravity. Since the second engaging portion 124 protrudes toward the engaging member 210 compared to the first engaging portion 122, the battery unit 10 moves relative to the battery holder 20 to the second position where the engaging portion 212 engages with the second engaging portion 124, as shown in fig. 8C.
As shown in fig. 8C, when the battery unit 10 is positioned at the second position, since the second engaging portion 124 can move relative to the end 112 of the battery 110, the user can apply an external force F to the operating portion 126, for example, push the operating portion 126 in a direction away from the battery holder 20, so that the operating portion 126 rotates about the rotation axis 160, and further, one end of the connecting movable plate 120 'adjacent to the first engaging portion 122 moves in a direction approaching to the battery holder 20, and the movable plate 120' is driven to rotate about the shaft portion 128 as a rotation center in a clockwise direction R, and further, the second engaging portion 124 is driven to rotate away from the engaging portion 212, as shown in fig. 8D. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move again along the disengagement direction D2 relative to the battery holder 20, for example, downward by gravity, so as to be detached from the battery holder 20, as shown in fig. 8E. In addition, the battery unit 10 of the present embodiment may have the elastic member 140 (not shown in the drawings) described in the foregoing embodiments, and after the external force F is released, the elastic member 140 may provide a restoring force to the movable plate 120', so that the movable plate 120' reversely rotates to move the second engaging portion 124 toward the battery fixing base 20, and further drive the operating portion 126 to return to the position where the free end thereof is closer to the battery fixing base 20 than the rotating shaft 160.
Fig. 9A to 9E are schematic views illustrating operations of a battery assembly 1 according to another embodiment of the present invention. As shown in fig. 9A, in this embodiment, the first engaging portion 122 and the second engaging portion 124 are respectively disposed at the end 112 of the battery 110, that is, the first engaging portion 122 and the second engaging portion 124 may be separate two components, rather than being integrated with the movable plates 120, 120'. For example, the first engaging portion 122 may be a hook or an engaging surface formed on the battery cover 130, and the second engaging portion 124 may be a member movably disposed on the battery cover 130. In this embodiment, the battery cover 130 preferably has a channel portion 138, and the second engaging portion 124 is movable in the channel portion 138 relative to the first engaging portion 122. For example, the middle portion of the second engaging portion 124 is located in the channel portion 138, and two ends of the second engaging portion respectively protrude from the battery cover 130 to serve as a portion for engaging with the locking member 210 and the operating portion 126 for operation by a user. In this embodiment, the second engaging portion 124 moves horizontally (or laterally) with respect to the battery cover 130 (or the end portion), that is, in a direction perpendicular to the disengaging direction D2 of the battery cell 10.
The operation of the second engaging portion 124 will be described with reference to fig. 9A to 9E, and the remaining operation of the battery assembly 1 will be described with reference to the foregoing embodiments. As shown in fig. 9A, the battery unit 10 is completely mounted on the battery holder 20, and the movement of the locking member 210 is limited by the lock of the lock 220, so that the locking portion 212 is kept engaged with the first engaging portion 122 of the battery unit 10, so as to limit the movement of the battery unit 10 relative to the battery holder 20 and to be positioned at the first position, i.e. the undetachable position. At this time, the projection of the second engaging portion 124 along the disengaging direction D2 is at least partially outside the end of the first engaging portion 122, that is, the second engaging portion 124 protrudes toward the locking member 210 compared to the first engaging portion 122.
As shown in fig. 9B, the lock 220 is changed from the locked state to the unlocked state, and the driving shaft 224 retracts to drive the locking member 210 to move away from the first engaging portion 122 in the unlocking direction D1 toward the accommodating space 2342, so as to release the engagement. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move in the disengaging direction D2 relative to the battery holder 20, for example, downward by gravity. Since the second engaging portion 124 protrudes toward the engaging member 210 compared to the first engaging portion 122, the battery unit 10 moves relative to the battery holder 20 to the second position where the engaging portion 212 engages with the second engaging portion 124, as shown in fig. 9C.
As shown in fig. 9C, when the battery unit 10 is positioned at the second position, the second engaging portion 124 is allowed to move inward of the battery 110 with respect to the first engaging portion 122 to release the engagement with the stopper 210. Specifically, the user may apply an external force F to the operation portion 126 of the second engaging portion 124, for example, push the operation portion 126 away from the battery holder 20, so that the second engaging portion 124 moves in the direction of application of force (or parallel to the moving direction of the locking member 210) in the channel portion 138 to be separated from the engaging portion 212, as shown in fig. 9D. That is, the second engaging portion 124 is retracted toward the inside of the battery 110, and the length of the second engaging portion 124 protruding toward the locking piece 210 with respect to the battery cover 130 is reduced. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move again along the disengagement direction D2 relative to the battery holder 20, for example, downward by gravity, so as to be detached from the battery holder 20, as shown in fig. 9E. In addition, the battery unit 10 of the present embodiment may have the elastic member 140 (not shown here) described in the foregoing embodiment, and after the external force F is released, the elastic member 140 may provide a restoring force to the second engaging portion 124, so that the second engaging portion 124 moves reversely to return to the position of the second engaging portion 124 closer to the battery holder 20 than the first engaging portion 122.
Fig. 10A to 10J are schematic views illustrating a cross-section and a bottom view of a battery assembly 1 in a disengaging direction D2 according to another embodiment of the invention, wherein fig. 10A, 10C, 10E, 10G and 10I are schematic views illustrating a cross-section and a bottom view of the battery assembly 1 in the disengaging direction D2, and fig. 10B, 10D, 10F, 10H and 10J are schematic views illustrating a bottom view of the battery assembly 1 in the disengaging direction D2. As shown in fig. 10A and 10B, in this embodiment, the first engaging portion 122 and the second engaging portion 124 are separate two members, and the direction in which the second engaging portion 124 moves laterally is different from the embodiment shown in fig. 9A. Similar to the embodiment of fig. 9A, the first engaging portion 122 may be a hook or an engaging surface formed on the battery cover 130, and the second engaging portion 124 may move laterally relative to the battery cover 130. The battery unit 10 further includes an operation portion 170, and the operation portion 170 is disposed corresponding to the second engaging portion 124. The operating portion 170 is forced (e.g., pushed by a user) to urge the second engaging portion 124 to move laterally relative to the first engaging portion 122 toward the battery 110. Specifically, the moving direction of the second engaging portion 124 is preferably perpendicular to the disengaging direction D2 of the battery unit 10 and the unlocking direction D1 of the locking member 210, that is, the moving direction of the second engaging portion 124, the unlocking direction D1 of the locking member 210, and the disengaging direction D2 of the battery unit 10 may represent directions of the X axis, the Y axis, and the Z axis of the XYZ three-dimensional space, respectively.
The operation of the second engaging portion 124 will be described with reference to fig. 10A to 10J, and the remaining operation of the battery assembly 1 will be described with reference to the foregoing embodiments. As shown in fig. 10A and 10B, the battery unit 10 is completely mounted on the battery holder 20, and the movement of the locking member 210 is limited by the lock of the lock 220, so that the locking portion 212 is kept engaged with the first engaging portion 122 of the battery unit 10, so as to limit the movement of the battery unit 10 relative to the battery holder 20 and to be positioned at the first position, i.e., the position that cannot be removed. At this time, the projection of the second engaging portion 124 along the disengaging direction D2 is at least partially outside the end of the first engaging portion 122, that is, the second engaging portion 124 protrudes toward the locking member 210 compared to the first engaging portion 122.
As shown in fig. 10C and 10D, the lock 220 is changed from the locked state to the unlocked state, and the driving shaft 224 retracts to drive the locking member 210 to move away from the first engaging portion 122 in the accommodating space 2342 along the unlocking direction D1, so as to release the engagement. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move in the disengaging direction D2 relative to the battery holder 20, for example, downward by gravity. Since the second engaging portion 124 protrudes toward the engaging member 210 compared to the first engaging portion 122, the battery unit 10 moves relative to the battery holder 20 to the second position where the engaging portion 212 engages with the second engaging portion 124, as shown in fig. 10E and 10F.
As shown in fig. 10E and 10F, when the battery unit 10 is positioned at the second position, the second engaging portion 124 is allowed to move laterally relative to the first engaging portion 122 toward the battery 110, so that the second engaging portion 124 is displaced from the engaging piece 210 to release the engagement. Specifically, the user may apply an external force F to the operation portion 170, for example, push the operation portion 170 toward the inside of the battery 110 along the short axis direction of the battery 110, so that the second engaging portion 124 moves in the force application direction to be displaced from the engaging portion 212, as shown in fig. 10G and 10H. That is, the length of the second engaging portion 124 protruding toward the locking piece 210 with respect to the battery cover 130 is not changed, but is changed in position so as to be displaced from the locking piece 210, for example, the projection of the second engaging portion 124 in the disengaging direction D2 does not overlap with the locking piece 210. In this embodiment, the direction in which the second engaging portion 124 moves laterally is perpendicular to the disengaging direction D1 and the unlocking direction D2. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move again in the unlocking direction D2 relative to the battery holder 20, for example, by moving downward by gravity, so as to be detached from the battery holder 20, as shown in fig. 10I and 10J. In addition, the battery unit 10 of the present embodiment may have the elastic member 140 (not shown here) described in the previous embodiment, and after the external force F is released, the elastic member 140 may provide a restoring force to the second engaging portion 124, so that the second engaging portion 124 moves reversely to return to the original position.
Fig. 11A to 11E are schematic views illustrating operations of a battery assembly 1 according to another embodiment of the present invention. As shown in fig. 11A, in this embodiment, the lock 180 of the battery assembly 1 is disposed in the battery unit 10 and coupled to the first engaging portion 122. When the lock 180 is in the locked state, the locking member 210 and the first engaging portion 122 are restricted from moving relative to each other to maintain engagement. When the lock 180 is in the unlocked state, the first engaging portion 122 is driven to move, so as to release the engagement between the locking member 210 and the first engaging portion 122. In other words, in this embodiment, the locking member 210 can be a fixed member, and the first engaging portion 122 and the second engaging portion 124 are movable members. Specifically, the lock 180 may have a similar structure to the lock 220, and the first engaging portion 122 in this embodiment is similar to the driving shaft 224 of the lock 220, so that the first engaging portion 122 can be adapted to be extended or retracted with low elongation or retraction according to the locked state or the unlocked state of the lock 180, so as to change the position of the engaging member 210 to form the engagement or release the engagement. For example, the second engaging portion 124 may have a structure similar to that of fig. 9A, so as to allow the second engaging portion 124 to move back and forth relative to the end of the battery 110, but not limited thereto. The second engaging portion 124 may also have a structure similar to that of fig. 10A to allow the second engaging portion 124 to move laterally with respect to the end of the battery 110.
The operation of the battery assembly 1 will be described with reference to fig. 11A to 11E. As shown in fig. 11A, the battery unit 10 is completely mounted on the battery holder 20, and the movement of the first engaging portion 122 is limited by the lock of the lock 180, so that the first engaging portion 122 of the battery unit 10 is engaged with the engaging portion 212 of the engaging member 210, and the battery unit 10 is limited to move relative to the battery holder 20 and be positioned at the first position, i.e., the undetachable position. At this time, the projections of the second engaging portion 124 and the first engaging portion 122 in the disengaging direction D2 at least partially overlap each other, and each at least partially overlap the engaging portion 212 of the engaging member 210.
As shown in fig. 11B, the lock 180 is changed from the locked state to the unlocked state, and the first engaging portion 122 is retracted in the unlocking direction D1, and moves away from the engaging portion 212 toward the inside of the battery 110 to release the engagement. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move along the disengaging direction D2 relative to the battery holder 20, for example, downward by gravity until the second engagement portion 124 engages with the engagement portion 212 to position the battery unit 10 at the second position, as shown in fig. 11C. That is, the lock 180 is changed from the locked state to the unlocked state, and the first engaging portion 122 is driven to move away from the second engaging portion 124 along the moving path of the disengaging direction D2, so that when the battery unit 10 moves along the disengaging direction D2, the locking portion 212 interferes (or engages) with the second engaging portion 124, and the battery unit 10 stops moving and is positioned at the second position.
As shown in fig. 11C, when the battery unit 10 is positioned at the second position, the second engaging portion 124 is allowed to move inward of the battery 110 with respect to the locking piece 210 to release the engagement with the locking piece 210. Specifically, the user may apply an external force F to the operation portion 126 of the second engaging portion 124, for example, push the operation portion 126 away from the battery holder 20, so that the second engaging portion 124 moves in the direction of application of force (or parallel to the moving direction of the first engaging portion 122) in the channel portion 138 to be separated from the engaging portion 212, as shown in fig. 11D. At this time, the lack of the engagement mechanism between the battery unit 10 and the battery holder 20 allows the battery unit 10 to move again along the disengagement direction D2 relative to the battery holder 20, for example, downward by gravity, so as to be detached from the battery holder 20, as shown in fig. 11E. In addition, the battery unit 10 of the present embodiment may have the elastic member 140 (not shown here) described in the previous embodiment, and after the external force F is released, the elastic member 140 may provide a restoring force to the second engaging portion 124, so that the second engaging portion 124 moves reversely to return to the original position.
In addition, in the above embodiment, other linkage mechanisms may be coupled to the operation portion to change the force applied to control the acting direction of the operation portion. Fig. 12A is a schematic view of a battery assembly 1 according to another embodiment of the present invention. In this embodiment, the battery cell 10 further includes an acting member 190. The acting element 190 is movably disposed at a side of the battery 110, and under the action of an external force F, the acting element 190 pushes the operating portion 126 to drive the second engaging portion 124 away from the locking element 210 to release the locking, where the external force F is applied in a direction perpendicular to the unlocking direction D1 and/or the disengaging direction D2. For example, one end of the acting member 190 may be coupled to the operation portion 126 of fig. 7A, and the other end of the acting member 190 may be connected to the battery cover 130 (or the battery 110) of the battery unit 10. The acting member 190 is at least partially exposed outside the battery unit 10, so that the user applies an external force F to drive the operation portion 126 to move. Next, with reference to fig. 12B and 12C, the operational relationship between the operation portion 126 and the operation element 190 will be described.
As shown in fig. 12B, the acting member 190 is preferably a deformable driving plate or a spring plate disposed on two sides of the battery unit 10, and two ends of the acting member 190 are coupled to the operating portion 126 and the battery cover 130 (or the battery 110), respectively. In this embodiment, the acting member 190 is elastically deformed under force to push against the operating portion 126, so that the operating portion 126 moves to the position shown in fig. 12C along the moving direction D3 relative to the reference plane P. For example, when the disengagement direction D2 is downward, by the arrangement of the acting element 190, the user can apply force to the acting element 190 disposed at the side of the battery unit 10 by using the thumb and the index finger while supporting the battery unit 10 with one hand, so that the acting element 190 moves (e.g. deforms and stretches) to push the operating portion 126 towards the battery fixing base 20, and further drives the second engaging portion 124 to rotate away from the locking element 210 to release the engagement. When the external force F is released, the operating portion 126 and the acting member 190 can be returned to the position shown in fig. 12B by the restoring force of the acting member 190. In other words, in the embodiment of fig. 12A, the moving direction D3 is the same as the direction of application of the external force F of fig. 7C, and the application direction of the external force F applied to the acting member 190 is perpendicular to the unlocking direction D1 and the disengaging direction D2 by the arrangement of the acting member 190, so as to increase the convenience of operation. The acting element 190 is not limited by the deformable driving plate or the elastic sheet in the embodiment, and the movement of the acting element 190 is not limited by deformation. In other embodiments, the acting element may be implemented as any convenient linkage mechanism, such as one or more linkage elements rotatably coupled to the operation portion 126, so as to control the movement of the operation portion 126 by the rotation and/or movement of the linkage element, thereby enhancing the convenience of operation. Fig. 13A is a schematic view of a battery assembly 1 according to another embodiment of the present invention; fig. 13B and 13C show the operation relationship between the operation portion 126 and the acting member 190', wherein fig. 13B and 13C are schematic plan views seen along the disengaging direction D2 of the battery cell 10. As shown in fig. 13A to 13B, in this embodiment, the acting member 190' includes a plurality of interlocking members 192, 194 and an elastic member 196 to form an interlocking member that acts together with the operation portion 126. For example, the linkage members 192, 194 may be implemented in the form of links, and the elastic member 196 may be implemented as a torsion spring. In this embodiment, two sets of the acting elements 190' are preferably disposed on both sides of the battery unit 10. The linkage member 192 extends from the side of the battery unit 10 toward the operation portion 126 and is pivotally connected to the linkage member 194, the torsion spring type elastic member 196 is disposed at the pivot of the linkage members 192 and 194, and the other side of the linkage member 194 opposite to the linkage member 192 is coupled to the operation portion 126. The acting element 190' may be pivotally connected to the housing of the battery 110 or the battery cover 130, and the two extension arms of the torsion spring abut against the linking elements 192 and 194, respectively. As shown in fig. 13B and 13C, when the acting member 190 'is stressed, for example, a user applies an external force F to the free end of the linking member 192, and rotates and compresses the torsion spring at the pivot point of the torsion spring, the linking member 194 of the acting member 190' rotates to push the operating portion 126 along the moving direction D3 relative to the reference surface, so that the movable plate 120 correspondingly rotates, and drives the second engaging portion 124 to move away from the locking member 210 to release the engagement, thereby allowing the battery unit 10 to be completely separated from the battery fixing base 20. When the external force F is released, the operating portion 126 and the acting member 190' can be returned to the position shown in fig. 13B by the restoring force of the torsion spring (i.e., the elastic member 196).
