Detailed Description
In order to make the aforementioned objects, features and advantages of the present invention comprehensible, embodiments accompanied with figures are described in detail below. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present invention. This invention may, however, be embodied in many different forms and should not be construed as limited to the embodiments set forth herein.
Referring to fig. 1 to 4, an embodiment of the present application provides a mechanical assembly 100 for a sunroof. The mechanical group 100 of the sunroof is used for driving a sunroof (not shown) to open and close. The mechanical set 100 of the sunroof comprises a guide rail assembly 110, a slider assembly 120, a positioning assembly 130, a lifting arm assembly 140, and a driving assembly 150. When the mechanical group 100 of the automobile sunroof is installed on an automobile, the guide rail assembly 110 is fixed on the automobile. The slider assembly 120 is in sliding engagement with the rail assembly 110. The slider assembly 120 is movable along a predetermined path on the rail assembly 110. The positioning assembly 130 is in sliding engagement with the rail assembly 110. Lift arm assembly 140 is rotatably coupled at one end to positioning assembly 130. The lifting arm assembly 140 is used for being fixedly connected with a sunroof of an automobile. The driving assembly 150 drives the slider assembly 120 to move.
Wherein the predetermined path includes a first segment and a second segment that is contiguous with the first segment. As the slider assembly 120 moves along the first segment of the predetermined path and moves in a direction closer to the second segment, the slider assembly 120 is able to drive the lift arm assembly 140 to rotate relative to the positioning assembly 130 and move the other end of the lift arm assembly 140 away from the rail assembly 110. When the slider assembly 120 is located at the second section of the predetermined path, the slider assembly 120 is locked with the positioning assembly 130, and the slider assembly 120 can drive the positioning assembly 130 and the lifting arm assembly 140 to perform a translational motion synchronously.
Specifically, when the mechanical group 100 of the sunroof is installed in the vehicle, the rail assembly 110 is fixedly installed on the frame of the roof of the vehicle. The guide rail assembly 110 has a predetermined path formed thereon, and when the driving assembly 150 drives the slider assembly 120 to slide along the guide rail assembly 110, the slider assembly 120 slides along the predetermined path and drives the lift arm assembly 140 to move. Because the arm lifting assembly 140 is fixedly connected with the automobile skylight, the arm lifting assembly 140 drives the automobile skylight to move, and then the automobile skylight is opened and closed. Further, the automotive sunroof may be a glass window, such as a front glass of a panoramic sunroof.
As shown in fig. 1 and 2, the drive assembly 150 may include a motor (not shown) and a flexible mechanical shaft 151. The mechanical flexible shaft 151 and the sliding block assembly 120 can be connected in a clamping groove connection mode. The mechanical flexible shaft 151 is arranged in a sliding groove matched with the mechanical flexible shaft 151 on the guide rail assembly 110. The mechanical flexible shaft 151 is driven by the motor to slide along the sliding groove, so that the sliding block assembly 120 can be driven to move along the guide rail assembly 110.
Specifically, one end of lift arm assembly 140 may be hingedly coupled to positioning assembly 130. As can be seen in fig. 2 and 3, in this embodiment, one end of positioning assembly 130 and lift arm assembly 140 are received in attachment bracket 160. Referring to fig. 1, a pin 161 is inserted through the connection bracket 160, the positioning assembly 130, and one end of the lifting arm assembly 140 in this order, so that one end of the lifting arm assembly 140 is rotatably connected to the positioning assembly 130 about the pin 161 as a rotation axis.
When the sunroof is in the fully closed state, the slider assembly 120 is located at the beginning of the first section (i.e., the point of the first section that is farthest from the second section). The end point of the first segment is adjacent to the start point of the second segment. When the slider assembly 120 reaches the end of the second section (i.e., the point of the second section furthest from the first section), the sunroof is in a fully open state. The following describes in detail the process from the closed state of the sunroof, to the tilting of the sunroof, and then to the full opening of the sunroof.
When the slider assembly 120 moves along the first segment of the predetermined path and the moving direction is toward the direction close to the second segment, the slider assembly 120 drives the lifting arm assembly 140 to rotate relative to the positioning assembly 130, and the other end of the lifting arm assembly 140 moves away from the guide rail assembly 110. One end of the lift arm assembly 140 is rotatably coupled to the positioning assembly 130, and the lift arm assembly 140 tilts with respect to the slider assembly 120 as the other end of the lift arm assembly 140 moves away from the rail assembly 110, see fig. 3. Until the slider assembly 120 moves to the end of the first section (i.e., the point of the first section adjacent to the second section), the lift arm assembly 140 tilts to the highest position relative to the slider assembly 120 (see the state of the lift arm assembly 140 in fig. 3). At this time, the lifting arm assembly 140 drives the sunroof to tilt to the highest position relative to the frame on the top of the automobile, so that the sunroof is in a tilting state from a closed state.
Then, the arm lifting assembly 140 continues to move along with the slider assembly 120 in a tilted state, at this time, the slider assembly 120 enters the second section from the first section and moves along the second section in a direction away from the first section, during the movement of the second section, the slider assembly 120 and the positioning assembly 130 are locked, and the slider assembly 120 drives the positioning assembly 130 and the arm lifting assembly 140 to move horizontally. Since the slider assembly 120 is locked with the positioning assembly 130, the slider assembly 120 drives the positioning assembly 130 to perform a synchronous translational motion along the second segment. Because slider assembly 120 drives and lifts arm assembly 140 and make translational motion, locating component 130 is connected with the one end of lifting arm assembly 140 to locating component 130 and the synchronous translational motion of lifting arm assembly 140, namely slider assembly 120, locating component 130 and lift arm assembly 140 three are the translational motion in step. Thus, the lift arm assembly 140 is less likely to move back and forth relative to the slider assembly 120 during the second stage of movement of the slider assembly 120. Until the slider assembly 120 moves to the end of the second section (i.e., the point of the second section furthest from the first section), the sunroof is fully open. At this moment, slider assembly 120 and locating component 130 still interlock each other, and locating component 130 is connected with the one end of lifting arm subassembly 140 to, after the sunroof was opened, lifting arm subassembly 140 was for slider assembly 120 is difficult for the front and back drunkenness, made the sunroof can be stable be in the open position.
In the mechanical set of the automobile sunroof, the lifting arm assembly 140 moves synchronously with the slider assembly 120 and the positioning assembly 130 in a tilting state until the automobile sunroof is completely opened. Because in this motion process and after the sunroof is opened, slider assembly 120 and locating component 130 are interlocking, locating component 130 is connected with the one end of lifting arm assembly 140 to avoid or reduced lifting arm assembly 140 and moved about for slider assembly 120, and then make the sunroof can be stable be in the open position.
Specifically, referring to fig. 1 to 3, the slider assembly 120 includes a first slider 120a and a second slider 120b, the first slider 120a and the second slider 120b may be in mating engagement, and the lifting arm assembly 140 is located between the first slider 120a and the second slider 120b, so that the lifting arm assembly 140 may be limited between the first slider 120a and the second slider 120b from two sides of the lifting arm assembly 140 when the lifting arm assembly 140 rotates, which is beneficial to position stabilization of the lifting arm assembly 140 when the lifting arm assembly 140 moves along with the slider assembly 120.
Further, a first linkage portion is disposed on the slider assembly 120, and a first matching structure is disposed on the lifting arm assembly 140. When the slider assembly 120 moves along the first section of the predetermined path, the first linkage portion cooperates with the first engagement structure to rotate the lifting arm assembly 140.
In particular, the first linkage may comprise a slider and the first mating structure may comprise a crank. The first linkage part and the first matching structure can form a slider-crank mechanism, so that the lifting arm assembly 140 is driven to rotate when the slider assembly 120 moves along the first section, and the tilting of the automobile skylight is facilitated.
Referring to fig. 1 to 3, in an embodiment, the first linkage portion includes a first sliding member 121, the first engaging structure is a first sliding slot 141 engaged with the first sliding member, and when the sliding block assembly 120 moves along a first section of the predetermined path, the first sliding member 121 moves in the first sliding slot 141, so as to drive the lifting arm assembly 140 to rotate.
Specifically, the first slider 121 may be a pin fixed to the slider assembly 120. The first slider 121 is fixedly connected to the first slider 120a and the second slider 120b, respectively. As shown in fig. 1 to 3, the first slide groove 141 has a substantially arc shape. And the first chute 141 is gradually curved downward as viewed from the right to the left. During the first stage of movement of the slider assembly 120, the first slider 121 slides from right to left, and the first slider 121 exerts an upward force on the inner wall of the first sliding groove 141. Since one end of the lifting arm assembly 140 is rotatably connected to the positioning assembly 130, and the positioning assembly 130 is stationary, the first sliding slot 141 rotates upward, and the lifting arm assembly 140 tilts upward relative to the slider assembly 120. By providing the first slider 121 and the first sliding groove 141, it is convenient to drive the lifting arm assembly 140 to tilt when the slider assembly 120 moves along the first section.
Further, a first locking portion is disposed on the positioning component 130, and a second matching structure matched with the first locking portion is disposed on the slider component 120. When the sliding block assembly 120 is located at the second section, the first locking portion is matched with the second matching structure, so that the sliding block assembly 120 is locked with the positioning assembly 130, and the positioning assembly 130 is connected with one end of the lifting arm assembly 140, so that the lifting arm assembly 140 moves along with the sliding block assembly 120 and the positioning assembly 130 in a synchronous motion manner in a tilting state and after an automobile skylight is opened, the lifting arm assembly 140 does not move back and forth easily relative to the sliding block assembly 120, and the automobile skylight can be located at an opening position stably. For example, the first locking portion may be a positioning block, and the second mating structure may be an elastic catch capable of being buckled with the positioning block.
Referring to fig. 1 to 3, in one embodiment, the second matching structure is a first groove 122, the first locking portion includes a protrusion 131 matching with the first groove 122, when the slider assembly 120 is located at the second section, the protrusion 131 is located in the first groove 122 and two sides of the protrusion 131 are respectively in contact connection with side walls of the first groove 122, so that the slider assembly 120 is locked with the positioning assembly 130.
Specifically, the slider assembly 120 is formed with a first recess 122. The positioning assembly 130 is provided with a protrusion 131. When the protrusion 131 is located in the first groove 122, the protrusion 131 is in contact connection with the side wall of the first groove 122, and the side wall of the first groove 122 limits the movement of the protrusion 131 toward the side wall of the first groove 122, that is, the protrusion 131 is caught in the first groove 122, so as to lock the slider assembly 120 and the positioning assembly 130.
Further, referring to fig. 4, the guide rail assembly 110 is provided with a second groove 111 matching with the protrusion 131, the second groove 111 is located above the first groove 122, and the protrusion 131 is located in the second groove 111 when the slider assembly 120 moves along the first section of the predetermined path. When the slider assembly 120 moves from the first stage to the second stage until the first groove 122 passes through the second groove 111, the protrusion 131 can fall into the first groove 122 from the second groove 111.
Specifically, with reference to fig. 1 and 4, during the first stage of movement of the slider assembly 120, the positioning assembly 130 is stationary and the protrusion 131 is located in the second groove 111 of the rail assembly 110. Since one end of the positioning member 130 is rotatably connected to one end of the lifting arm member 140 via the connecting bracket 160, the end of the positioning member 130 provided with the protrusion 131 is rotatable up and down. When the slider assembly 120 moves from the first section to the second section until the first groove 122 passes through the second groove 111, the protrusion 131 falls down from the second groove 111 into the first groove 122, so that the protrusion 131 is caught in the first groove 122, i.e. the positioning assembly 130 is locked with the slider assembly 120. The protrusions 131 then move in translation in unison with the slider assembly 120 in the second stage, thereby causing the positioning assembly 130 to move in translation in unison with the slider assembly 120.
Further, referring to fig. 1 and 3, a driving link 123 is formed on the slider assembly 120, the first groove 122 is opened on the driving link 123, and the driving link 123 is lower in height than the second groove 111. So that when the slider assembly 120 moves from the first section to the second section, the first groove 122 on the driving rod 123 gradually approaches the second groove 111 until the first groove 122 passes through the second groove 111, the protrusion 131 falls into the first groove 122, so that the driving rod 123 continues to move, and the protrusion 131 is pulled to move synchronously. The locking of the slider assembly 120 with the positioning assembly 130 is facilitated by the provision of the actuating rod 123.
Further, as shown in fig. 5, the first groove 122 has a first sidewall 122a and a second sidewall 122b opposite to the first sidewall 122a, and the second sidewall 122b is hook-shaped, so that when the protrusion 131 is located in the first groove 122, the second sidewall 122b hooks the protrusion 131 to provide resistance to the movement of the protrusion 131 toward the first stage, as shown in fig. 3. When the slider assembly 120 enters the second section and moves away from the first section, the direction in which the second side wall 122b hooks the protrusion 131 is the same as the moving direction of the slider assembly 120, so that the second side wall 122b can block the protrusion 131 from moving towards the first section, and forcefully drive the protrusion 131 to move along the second section towards the direction away from the first section, thereby more reliably locking and synchronizing the positioning assembly 130 and the slider assembly 120.
In one embodiment, as shown in fig. 5, the first sidewall 122a is inclined with respect to the vertical direction. Referring to fig. 3 and 4, when the slider assembly 120 moves from the second stage to the first stage until the first groove 122 passes through the second groove 111, the guide rail assembly 110 can limit the movement of the positioning assembly 130 in the horizontal direction, so that the first sidewall 122a pushes the protrusion 131 into the second groove 111.
Specifically, during the opening and closing of the sunroof, the slider assembly 120 moves from the second section to the first section until the first groove 122 passes the second groove 111, and the first side wall 122a is inclined, thereby applying an obliquely upward force to the protrusion 131. At this time, since the guide rail assembly 110 limits the horizontal forward movement of the positioning assembly 130, the horizontal forward movement of the protrusion 131 is limited, and the protrusion 131 moves upward into the second groove 111, so that the protrusion 131 is disengaged from the first groove 122, and the positioning assembly 130 and the slider assembly 120 are released from each other.
Specifically, one end of the positioning assembly 130 and the lifting arm assembly 140 are rotatably connected through the connecting bracket 160 and the pin 161. When the first groove 122 passes through the second groove 111, the connecting bracket 160 is horizontally abutted against the rail assembly 110, so that the rail assembly 110 limits the horizontal movement of the positioning assembly 130.
Further, as shown in fig. 1 and fig. 3, a third groove 142 is formed in the lifting arm assembly 140, a limiting portion 124 is formed in the slider assembly 120, an opening of the third groove 142 faces a direction in which the first section is close to the second section, and when the slider assembly 120 is located at an end of the first section far from the second section, the limiting portion 124 is located in the third groove 142 and abuts against an inner wall of the third groove 142.
Specifically, the stopper 124 may be a pin. When the slider assembly 120 is located at an end of the first section remote from the second section, i.e., the slider assembly 120 is located at the beginning of the first section, the sunroof is fully closed. The position-limiting portion 124 is located in the third groove 142 and abuts against the inner wall of the third groove 142. Specifically, the position-limiting portion 124 may abut against the bottom wall of the third groove 142, and the position-limiting portion 124 may block the arm lifting assembly 140 from moving toward the direction facing the bottom wall of the third groove 142. The position-limiting portion 124 can abut against the upper and lower sidewalls of the third groove 142, and the position-limiting portion 124 can block the arm-lifting assembly 140 from swinging in the up-down direction. Furthermore, the limiting portion 124 abuts against the inner wall of the third groove 142, so that the sunroof is very stable and reliable when the sunroof is completely closed.
Further, referring to fig. 1 to 3, two ends of the limiting portion 124 are respectively connected to the first slider 120a and the second slider 120 b. So that the stopper portion 124 is sandwiched between the first slider 120a and the second slider 120b, facilitating the location of the stopper portion 124. And since the lifting arm assembly 140 is located between the first slider 120a and the second slider 120b, the third groove 142 on the lifting arm assembly 140 is convenient to be matched with the limiting portion 124 when the slider assembly 120 is located at the beginning of the first segment.
Furthermore, a second sliding slot 132 is disposed on the positioning assembly 130, a second sliding member 143 slidably engaged with the second sliding slot 132 is fixedly connected to the arm lifting assembly 140, and when the arm lifting assembly 140 rotates relative to the positioning assembly 130, the second sliding member 143 is driven to slide in the second sliding slot 132.
Specifically, as shown in fig. 1 to 3, the second slider 143 may be a pin. When the lifting arm assembly 140 rotates relative to the positioning assembly 130, the second sliding member 143 slides in the second sliding slot 132. The sliding engagement of second runner 132 and second slide 143 allows positioning assembly 130 to be positioned close to lift arm assembly 140, facilitating positional stability of lift arm assembly 140 as lift arm assembly 140 is rotated relative to positioning assembly 130.
The following describes in detail the process from the fully open position of the sunroof to the lowering of the lift arm assembly until the sunroof is fully closed.
When the slider assembly 120 is at the end of the second section, the sunroof is in a fully open position. The slider assembly 120 moves along the second segment of the predetermined path and the moving direction moves towards the direction close to the first segment, at this time, the lifting arm assembly 140 keeps the tilting state, and the protrusion 131 is blocked in the first groove 122, i.e. the slider assembly 120 is locked with the positioning assembly 130. The slider assembly 120, the positioning assembly 130 and the lifting arm assembly 140 move in a synchronous translational motion. Until the first groove 122 passes through the second groove 111, the first sidewall 122a is a slope, and since the horizontal movement of the positioning assembly 130 is limited, the first sidewall 122a pushes the protrusion 131 into the second groove 111 above, so that the protrusion 131 is separated from the first groove 122, and the positioning assembly 130 and the slider assembly 120 are released from each other. The slider assembly 120 then enters the first section from the second section and moves away from the second section. At this time, the slider assembly 120 drives the lifting arm assembly 140 to rotate relative to the positioning assembly 130, and the lifting arm assembly 140 rotates in a direction close to the slider assembly 120, i.e., the lifting arm assembly 140 sinks close to the slider assembly 120. When the sliding block assembly 120 moves to the starting point of the first section, the lifting arm assembly 140 drives the sunroof to sink to the lowest position, so that the sunroof is completely closed.
