Detailed Description

In order to make the objects, technical solutions and advantages of the present utility model more apparent, the technical solutions of the present utility model will be clearly and completely described below with reference to specific embodiments of the present utility model and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, embodiments of the utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

The technical scheme disclosed by each embodiment of the utility model is described in detail below with reference to the accompanying drawings.

As shown in fig. 1 to 9, the embodiment of the utility model discloses an electronic lock, which may be a fingerprint lock, a coded lock or an intelligent lock, although the electronic lock may be of other types. The embodiment of the utility model does not limit the specific types of the electronic lockset. The disclosed electronic lock includes a lock body 100, a battery 200, an elastic clasp 300, and an elastic abutment 510.

The lock body 100 is a body structure of an electronic lock, and the lock body 100 includes, but is not limited to, a lock housing, a mechanical switch, a control chip, a circuit structure, and other electronic components. The lock body 100 is provided with a battery mounting groove 110, and the battery 200 can be mounted in the battery mounting groove 110. Specifically, the lock body 100 may include a lock housing on which the battery mounting groove 110 is formed, and a conductive connection member fixedly installed in the battery mounting groove 110. When the battery 200 is mounted in the battery mounting groove 110, the positive and negative poles of the battery 200 bear against the corresponding poles of the conductive connection member, which can both enable electrical connection with the battery 200. The battery 200 transfers electrical energy to other circuit structures and electronic components through conductive connections.

The elastic buckle 300 is connected with the lock body 100, specifically, the elastic buckle 300 is connected with the lock housing. The elastic buckle 300 may be snap-fitted with a side surface of the battery 200 facing away from the battery mounting groove 110 to restrict movement of the battery 200 toward the notch of the battery mounting groove 110. At this time, when the battery 200 is mounted into the battery mounting groove 110, the clip 330 of the elastic clip 300 can be pressed against a side surface of the battery 200 facing away from the battery mounting groove 110, thereby limiting movement of the battery 200 toward the notch direction of the battery mounting groove 110. The battery 200 is thus restrained within the battery mounting groove 110. The above-mentioned surface of the battery 200 on the side facing away from the battery mounting groove 110 refers to the surface of the battery 200 on the side exposed to the battery mounting groove 110, and can be understood as the top surface of the battery 200.

When the battery 200 needs to be disassembled, the user applies an acting force to the elastic buckle 300 to deform the elastic buckle 300, so that under the condition of driving the elastic buckle 300 to deform, the clamping fit between the elastic buckle 300 and the battery 200 can be released, and the situation can be understood as releasing the limit of the elastic buckle 300 to the battery 200, so that the battery 200 is disassembled.

Further, the elastic abutment 510 is located in the battery mounting groove 110 and is disposed on a sidewall of the battery mounting groove 110. The elastic buckle 300 and the elastic abutment 510 are respectively located at opposite sides of the battery mounting groove 110. Specifically, the elastic buckle 300 and the elastic abutment 510 may be arranged along the length direction of the battery mounting groove 110, or may be arranged along the width direction of the battery mounting groove 110. When the battery 200 is mounted into the battery mounting groove 110, the elastic abutment 510 may abut against the battery 200 in a direction toward the elastic buckle 300. At this time, the elastic buckle 300 and the elastic abutment 510 constitute a clamping structure, thereby clamping the battery 200. Specifically, the elastic abutment 510 may have a connection end, which may be connected with the sidewall of the battery mounting groove 110, and an abutment end, which may abut against the battery 200. The elastic abutment 510 may be an elastic structure such as a spring plate or a spring, but may be other elastic structures, which are not limited herein.

During the assembly and disassembly of a particular battery 200, the battery 200 has first and second ends disposed opposite one another, where the first end may be the end of the battery 200 facing the resilient abutment 510 and the second end may be the end of the battery 200 facing the resilient catch 300. First, the first end is placed in the battery mounting groove 110, and the user applies a force to the second end of the battery 200, so that the elastic abutment 510 is compressed, and a larger space can be reserved, so that the battery 200 can be mounted in the battery mounting groove 110. Then, the user applies a force to the elastic buckle 300 to deform the elastic buckle 300, so that the buckle head 330 of the elastic buckle 300 moves to a position not interfering with the battery 200, and then the second end is placed into the battery mounting groove 110, the user removes the force to the elastic buckle 300, the elastic buckle 300 is restored to deform, and the buckle head 330 is clamped on the battery 200.

When the battery 200 is detached, the user applies a force to the elastic buckle 300 to deform the elastic buckle 300, so that the buckle head 330 of the elastic buckle 300 moves to a position not interfering with the battery 200, and then the user takes the battery 200 out of the battery mounting groove 110 from the second end of the battery 200, thereby completing the detachment operation of the battery 200.

In the embodiment disclosed in the application, the elastic buckle 300 can block the battery 200, and further limit the battery 200 along the notch direction of the battery mounting groove 110. Meanwhile, the elastic abutting piece 510 can abut against the battery 200 along the direction towards the elastic buckle 300, so that the elastic abutting piece 510 and the elastic buckle 300 can form a clamping structure to clamp the battery 200, the risk that the battery 200 is loose or is separated from the battery mounting groove 110 due to external force impact can be effectively avoided, and the risk that the battery 200 and the lock body 100 are disconnected can be reduced, so that the safety and reliability of the electronic lock are improved.

In addition, the electronic lock adopts the elastic buckle 300 to carry out limit clamping on the battery 200, and the elastic buckle 300 realizes clamping and separating with the battery 200 through self elastic deformation, so that the elastic buckle 300 has a simple structure, and the material cost and the assembly cost of the electronic lock are saved.

In an alternative embodiment, the elastic clasp 300 may include a connection arm 310, an elastic arm 320, and a clasp 330, where the connection arm 310 is connected to the latch body 100, and where the elastic clasp 300 is connected to the latch body 100 through the connection arm 310. The end of the connection arm 310 facing the bottom of the battery mounting groove 110 may be connected with the end of the elastic arm 320 facing the bottom of the battery mounting groove 110. The elastic arm 320 is provided with a buckle 330 at one end facing the notch of the battery mounting groove 110, and the buckle 330 can be in clamping fit with one side surface of the battery 200 facing away from the battery mounting groove 110. At this time, the elastic arm 320 extends along the groove bottom of the battery mounting groove 110 to the notch direction thereof.

Under the condition that the elastic arm 320 is deformed, the buckle 330 is driven to release the clamping engagement with the battery 200. Specifically, the user applies a force to the end of the elastic arm 320 facing the notch of the battery mounting groove 110, so that the end of the elastic arm 320 facing the notch of the battery mounting groove 110 moves toward the side facing away from the battery 200, thus driving the button head 330 away from the battery 200 until the button head 330 is separated from the battery 200.

In this solution, the buckle 330 and the elastic arm 320 form an "L" structure, which can be understood that the buckle 330 and the elastic arm 320 form a step bayonet, and the edge of the battery 200 is clamped in the step bayonet formed by the buckle 330 and the elastic arm 320, so that the holding force of the elastic buckle 300 on the battery 200 can be improved.

Specifically, since the elastic arm 320 extends along the slot bottom of the battery mounting slot 110 to the slot opening direction thereof, the deformation direction of the elastic arm 320 is perpendicular to the extending direction thereof, and the deformation direction of the elastic arm 320 is perpendicular to the limit direction of the buckle 330 on the battery 200, so that the elastic arm 320 is prevented from deforming when the battery 200 receives an impact force in the slot opening direction of the battery mounting slot 110, thereby further avoiding the risk that the battery 200 is separated from the battery mounting slot 110, and further improving the safety and reliability of the electronic lock.

The connecting arm 310 in the above embodiment is used to connect the elastic buckle 300 with the lock body 100. Specifically, a side surface of the connection arm 310 facing away from the elastic arm 320 may be adhered, riveted or welded to a side wall of the battery mounting groove 110. Of course, other means of attachment may be used, and are not limited in this regard. Of course, the elastic arm 320 may be directly connected to the lock body 100, that is, the connecting arm 310 is a fixed structure on the lock body 100.

In another alternative embodiment, the electronic lock may further include an elastic filling portion 340, and the elastic filling portion 340 may be filled between the elastic arm 320 and the connection arm 310. Here, the elastic filling portion 340 has a certain elasticity, and when the elastic arm 320 is elastically deformed, the elastic arm 320 compresses the elastic filling portion 340 to elastically deform.

In this embodiment, the elastic filling portion 340 can prevent impurities from falling into the gap between the elastic arm 320 and the connecting arm 310, so as to avoid the risk of causing the functional failure of the elastic buckle 300. In addition, the elastic filler 340 can provide a reaction force to the elastic arm 320, so that the risk of elastic failure of the elastic arm 320 due to excessive compression of the elastic arm 320 can be avoided.

Alternatively, the elastic filling portion 340 may be an elastic structure such as foam, rubber, etc., and of course, the elastic filling portion 340 may be other structures, which is not limited herein.

In another alternative embodiment, the number of the elastic arms 320 of the elastic buckle 300 may be plural, and the plural elastic arms 320 may be sequentially connected to form a multi-stage elastic arm structure. For example, the plurality of elastic arms 320 are sequentially connected to form a "W" structure, but other structures are possible, and are not limited herein.

In the above embodiment, during the process of mounting and dismounting the battery 200, the battery is easily scratched or collided with the elastic arm 320, and the elastic arm 320 is easily damaged.

In this regard, in an alternative embodiment, the side wall of the battery mounting groove 110 may be provided with a receiving cutout 120 penetrating in the notch direction of the battery mounting groove 110, and at least portions of the connection arm 310 and the elastic arm 320 may be located in the receiving cutout 120. Specifically, the connecting arm 310 may be attached or fixed to the side wall of the accommodating opening 120. In this solution, the part of the battery mounting groove 110 may be provided with a receiving opening 120 in communication with the part for mounting the elastic arm 320 and the connecting arm 310, so that the elastic arm 320 and the connecting arm 310 can be hidden in the receiving opening 120, thereby avoiding the risk of damaging the elastic arm 320.

In addition, the elastic arm 320 and the connecting arm 310 are hidden in the accommodating opening 120, so that the battery mounting groove 110 is prevented from being occupied by the elastic buckle 300, and therefore, one end of the battery 200, which is close to the elastic arm 320, can be abutted to the inner wall of the battery mounting groove 110, and further, the risks of tilting and shaking of the battery 200 are avoided.

In an alternative embodiment, the side of the clip 330 facing away from the bottom of the battery mount channel 110 may be provided with a first guide surface 331, the first guide surface 331 being in guided engagement with the battery 200. The first guide surface 331 may guide the battery 200 when the battery 200 is mounted in the battery mounting groove 110, thereby facilitating sliding of the battery 200 into the battery mounting groove 110.

Specifically, it is known from the above that the second end of the battery 200 may be the end of the battery 200 facing the elastic buckle 300. At this time, the user presses the second end of the battery 200, the second end contacts the first guiding surface 331, the second end presses the buckling head 330, and the buckling head 330 drives the elastic arm 320 to deform, so that the elastic arm 320 deforms until the second end passes over the buckling head 330 and moves to the bottom end of the buckling head 330. At this time, since the battery 200 is not in contact with the buckle 330, the elastic arm 320 is restored to its elastic deformation, so that the buckle 330 is engaged with the battery 200.

In this case, the self-guide assembly is performed through the first guide surface 331 during the mounting of the battery 200 to the battery mounting groove 110, and thus, the user does not need to directly press the elastic arm 320, thereby making the assembly operation of the battery 200 simpler.

Alternatively, the first guiding surface 331 may be an arc surface, an inclined surface, or a combination of an arc surface and an inclined surface, which is not limited herein.

In order to further improve the safety and reliability of the electronic lock. In another alternative embodiment, the notch of the battery mounting groove 110 may be further provided with a blocking wall 400, and the blocking wall 400 and the elastic buckle 300 may be located at opposite sides of the battery mounting groove 110, respectively. At this time, since the elastic buckle 300 and the elastic abutment 510 are also located at opposite sides of the battery mounting groove 110, respectively, the retaining wall 400 and the elastic abutment 510 are located at the same side of the battery mounting groove 110. Retaining wall 400 may be in positive engagement with a side surface of battery 200 facing away from battery mounting slot 110 to limit movement of battery 200 toward the slot of battery mounting slot 110.

In this embodiment, the elastic buckle 300 is used for limiting the second end of the battery 200, and the retaining wall 400 may be used for limiting the first end of the battery 200. At this time, the elastic buckle 300 and the retaining wall 400 block the opposite ends of the battery 200, so that the risk that the battery 200 is loosened or separated from the battery mounting groove 110 due to external force impact is further avoided, and the safety and reliability of the electronic lock are further improved.

In the above embodiment, since the retaining wall 400 cannot or hardly deform, the first end needs to be avoided from the retaining wall 400 when being placed in the battery mounting groove 110.

In another alternative embodiment, the number of the retaining walls 400 may be plural, and the plurality of retaining walls 400 may be spaced apart on the same side of the battery mounting groove 110. This arrangement can further improve the holding force for the first end of the battery 200.

In a specific embodiment, the number of retaining walls 400 may be two, the number of elastic buckles 300 may be one, and the two retaining walls 400 may be symmetrically disposed with respect to the elastic buckles 300. In this embodiment, the elastic buckle 300 is clamped in the middle area of the second end of the battery 200, and the two retaining walls 400 are distributed on two sides of the first end. At this time, the battery 200 can have a relatively uniform holding force, and the number of the elastic buckles 300 and the retaining walls 400 is reduced, so that the battery 200 can be disassembled conveniently.

In another alternative embodiment, the side of the blocking wall 400 facing the bottom of the battery mounting groove 110 may be provided with a second guide surface 401, and the second guide surface 401 may be in guide engagement with the battery 200. At this time, when the first end moves toward the side of the retaining wall 400, the second guiding surface 401 can be in guiding fit with the first end of the battery 200, so as to avoid the risk of jamming or blocking between the first end of the battery 200 and the retaining wall 400, and further improve the reliability of the assembly of the battery 200.

Alternatively, the second guiding surface 401 may be an arc surface, an inclined surface, or a combination of an arc surface and an inclined surface, which is not limited herein.

In the above embodiment, the elastic buckle 300 and the elastic abutment 510 are respectively located at two opposite sides of the battery mounting groove 110, and it can be considered that the elastic buckle 300 and the elastic abutment 510 are distributed along the length direction of the battery mounting groove 110, so the elastic buckle 300 and the elastic abutment 510 limit the degree of freedom of the battery 200 in the length direction. The battery mounting groove 110 and the battery 200 have a larger gap in the width direction, so that the battery 200 is easy to move or shake along the width direction of the battery 200 groove, and the risk of disconnection between the battery 200 and the lock body 100 is increased.

In another alternative embodiment, the side walls of the battery mounting groove 110 adjacent to the elastic buckle 300 and the elastic abutment member 510 may be provided with a first limiting rib 520, and the first limiting rib 520 may be located in the battery mounting groove 110, and the first limiting rib 520 may be in a limiting fit with the battery 200 along a direction toward the first limiting rib 520. The direction toward the first stopper rib 520 is understood herein to be the direction in which the side wall of the battery mounting groove 110 provided with the first stopper rib 520 is located.

The side walls of the battery mounting groove 110 adjacent to the elastic buckle 300 and the elastic abutment 510 are understood as two side walls arranged in the width direction of the battery mounting groove 110. Be provided with first spacing muscle 520 on two lateral walls that the width direction of battery mounting groove 110 was arranged, consequently first spacing muscle 520 can carry out spacingly to the degree of freedom of battery 200 along the width direction of battery mounting groove 110, has consequently avoided battery 200 to take place to remove or rock the risk along the width direction of battery mounting groove 110, and then has reduced the risk that battery 200 and tool to lock main part 100 are broken circuit.

Specifically, the battery mounting groove 110 includes a first side wall 111, a second side wall 112, a third side wall 113 and a fourth side wall 114 that are connected end to end, the first side wall 111 is disposed opposite to the third side wall 113, and the first side wall 111 and the third side wall 113 are distributed along the length direction of the battery mounting groove 110. The second side wall 112 is disposed opposite to the fourth side wall 114, and the second side wall 112 and the fourth side wall 114 are distributed along the width direction of the battery mounting groove 110. The elastic buckle 300 is located on the side where the first sidewall 111 is located. The retaining wall 400 and the elastic abutment may both be located on the side of the third sidewall 113. The first stop rib 520 may be disposed on the second side wall 112 and the fourth side wall 114.

In the above embodiment, the number of the first limiting ribs 520 may be plural, and the first limiting ribs 520 may be spaced apart from the second side wall 112 and the fourth side wall 114. Specifically, the plurality of first stopper ribs 520 on the second and fourth side walls 112 and 114 may be spaced apart along the length direction of the battery mounting groove 110.

In another alternative embodiment, a second limiting rib 530 is disposed on the side wall of the battery mounting groove 110 on the same side as the elastic buckle 300, and the second limiting rib 530 may be located in the battery mounting groove 110, where the second limiting rib 530 may be in a limiting fit with the battery 200 along a direction toward the second limiting rib 530. At this time, the first side wall 111 of the battery mounting groove 110 may be provided with the second stopper rib 530. In this solution, the second limiting rib 530 can further increase the deformation of the elastic abutting element 510, so the crimping force of the elastic abutting element 510 to the battery 200 can be increased, so the holding force of the battery 200 is further increased, and the risk of the battery 200 being electrically connected with the lock body 100 due to the shaking of the battery 200 is avoided, thereby the safety and reliability of the electronic lock are further improved.

In an alternative, the above elastic buckle 300, the elastic abutment 510, the retaining wall 400, the first stopper rib 520 and the second stopper rib 530 are provided on the battery mounting groove 110. At this time, the elastic buckle 300 and the blocking wall 400 limit the battery 200 in the height direction of the battery mounting groove 110. The elastic buckle 300, the second stopper rib 530 and the elastic abutment 510 limit the battery 200 along the length direction of the battery mounting groove 110. The first stopper rib 520 limits the battery 200 in the width direction of the battery mounting groove 110. Therefore, the above solution limits the degrees of freedom along the height, width and length of the battery mounting groove 110, so as to effectively avoid the risk of failure of the electronic lock due to shaking or movement of the battery 200 in the battery mounting groove 110.

In the above embodiment, the battery 200 is exposed to the battery mounting groove 110 in a smaller volume, so that the user has a greater difficulty in removing the battery 200 from the battery mounting groove 110. Based on this, in an alternative embodiment, the edge of the notch of the battery mounting groove 110 may be provided with a finger-inserting groove 130, and the finger-inserting groove 130 may communicate with the battery mounting groove 110. The finger-inserting groove 130 may be located on the same side of the battery mounting groove 110 as the elastic buckle 300. When the battery 200 is disassembled, the fingers of the user can be inserted into the finger inserting grooves, so that the contact area between the fingers and the battery 200 is increased, the battery 200 is convenient to disassemble from the battery mounting groove 110 by the user, and the disassembly difficulty of the battery 200 is reduced.

Alternatively, the finger-inserting groove 130 may be semicircular, rectangular, crescent-shaped, or of course, and may be of other shapes, without limitation.

Alternatively, the number of fingers extending into the recess 130 may be plural. In a specific embodiment, the number of the fingers extending into the grooves 130 may be two, and the two fingers extending into the grooves 130 are symmetrically distributed about the elastic buckle 300.

In the above embodiment, the deformation of the elastic abutment member 510 is smaller due to the influence of the side wall of the battery mounting groove 110, so that the holding force of the elastic abutment to the battery 200 is smaller, and the reliability and safety of the electronic lock are poorer.

Based on this, in another alternative embodiment, the side wall of the battery mounting groove 110 is provided with the avoidance hole 140, and at least part of the elastic abutment 510 may be disposed opposite to the avoidance hole 140. In this scheme, when the battery 200 can drive the elastic contact 510 into the avoidance hole 140, the deformation of the elastic contact 510 can be increased, so as to improve the holding force of the elastic contact on the battery 200, and further improve the reliability and safety of the electronic lock.

The foregoing embodiments of the present utility model mainly describe differences between the embodiments, and as long as there is no contradiction between different optimization features of the embodiments, the embodiments may be combined to form a better embodiment, and in view of brevity of line text, no further description is provided herein.

The foregoing is merely exemplary of the present utility model and is not intended to limit the present utility model. Various modifications and variations of the present utility model will be apparent to those skilled in the art.
