Description

Technical Field

[0001] This utility model relates to an automotive accessory, and more particularly to an electronic lock for the trunk of a car. Background Technology

[0002] As we all know, car trunks are indispensable. They are used to lock the trunk to the car body when it is not needed, thus preventing the trunk from being opened accidentally.

[0003] However, in existing applications of locks used to secure the trunk of cars, they can only be unlocked using electric drive, which results in a single mode of operation.

[0004] Therefore, there is an urgent need for an electronic lock for the trunk of a car to overcome the above-mentioned defects. Utility Model Content

[0005] The purpose of this invention is to provide an electronic lock for the trunk of a car that can be opened electrically or manually and reduces the exposure of electromagnetic push rods and moving parts.

[0006] To achieve the above objectives, the electronic trunk lock of this utility model includes a base, a lock hook rotatably mounted on the base, a blocking member rotatably mounted on the base, a movable member connected to the blocking member, a traction member connected to the movable member and exposed on the base, and an electromagnetic push rod mounted on the base. The electromagnetic push rod has a sliding telescopic end connected to the movable member. During sliding and telescopic movement, the sliding telescopic end, through the movable member, rotates the blocking member to a blocking position that blocks the rotation of the lock hook or to a releasing position that disengages from the blocking position. The traction member, through the movable member, rotates the blocking member from the blocking position to the releasing position. The lock hook can rotate to a locking position where it locks the object together with the base or to a releasing position where it releases the object. When in the blocking position, the blocking member prevents the lock hook from switching between the locking and releasing positions.

[0007] Compared with existing technologies, the electromagnetic push rod has a sliding telescopic end that is assembled and connected to the moving part. During the sliding telescopic process, the sliding telescopic end drives the blocking part to rotate to the blocking position where the blocking hook rotates or to the releasing position where the blocking hook rotates. The traction part can drive the blocking part to rotate from the blocking position to the releasing position through the moving part. This design allows the user to rotate the blocking part to the unlocking position by electric drive or manual means, thus allowing the lock hook to unlock the locked object. Furthermore, since the electromagnetic push rod or traction part drives the blocking part to rotate from the blocking position to the releasing position through the moving part, the moving part and the electromagnetic push rod can be hidden in the base, reducing the exposure of the moving part and the electromagnetic push rod, thereby protecting the moving part and the electromagnetic push rod.

[0008] Preferably, the blocking member and the locking hook are arranged sequentially along the extension direction of the sliding telescopic end, and the moving member is spaced apart from the blocking member in the direction of the rotation center line of the blocking member.

[0009] Preferably, the base includes a housing and a frame that are stacked and fixed together in the direction of the rotation center line of the blocking member. The blocking member and the locking hook are assembled in the frame. The blocking member is provided with a linkage post that extends in the direction of the rotation center line of the blocking member and partially extends into the housing. The housing has a clearance through hole for the linkage post to extend into and to provide clearance for the linkage post that rotates with the blocking member. The moving member and the electromagnetic push rod are assembled in the housing. The moving member has a linkage groove that cooperates with the linkage post. The traction member extends out of the housing.

[0010] Preferably, the linkage post is located at the end of the blocking member away from the rotation center line of the blocking member; the clearance through hole extends in an arc around the rotation center line of the blocking member.

[0011] Preferably, the blocking member has a recessed structure on the side facing the locking hook, and the locking hook has a protruding structure on the side facing the blocking member; or, the blocking member has a protruding structure on the side facing the locking hook, and the locking hook has a recessed structure on the side facing the blocking member; the engagement and disengagement of the protruding structure and the recessed structure can correspondingly cause the blocking member to disengage from or block the locking hook.

[0012] Preferably, the periphery of the blocking member has a first arcuate profile that extends arcuately around the rotation center line of the blocking member and faces the locking hook, the periphery of the locking hook has a second arcuate profile that extends arcuately around the rotation center line of the blocking member and faces the first arcuate profile, and the periphery of the protrusion structure on the locking hook has a third arcuate profile that is tangent to the second arcuate profile and convex in the opposite direction, a straight profile that is opposite to the third arcuate profile, and an arcuate transition profile connecting the third arcuate profile and the straight profile.

[0013] Preferably, the electronic lock for the trunk of a car of this invention further includes a return spring for rotating the lock hook from the locked position to the unlocked position, the return spring being disposed on both the lock hook and the frame.

[0014] Preferably, the blocking member and the locking hook are each a sheet-like structure, and the return spring is a torsion spring.

[0015] Preferably, the locking hook is provided with a separating limiting hole, which also penetrates the periphery of one side of the locking hook. The entrance of the separating limiting hole is arranged at an increasing angle along the penetrating direction of the separating limiting hole. The frame is provided with an avoidance channel, which overlaps with the separating limiting hole when the locking hook rotates to the locking position, and is misaligned with the separating limiting hole when the locking hook rotates to the unlocking position.

[0016] Preferably, mounting brackets are bent out of the frame and arranged side by side at a distance from the housing, and the mounting brackets also extend along the sliding and telescopic direction of the sliding and telescopic end. Attached Figure Description

[0032] To explain the technical content and structural features of this utility model in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0033] Please see Figures 1 to 4 The electronic bumper lock 100 for the trunk of a car in the first embodiment includes a base 10, a lock hook 20 rotatably mounted on the base 10, a blocking member 30 rotatably mounted on the base 10, a movable member 40 arranged in conjunction with the blocking member 30, a traction member 50 assembled and connected to the movable member 40 and exposed on the base 20, and an electromagnetic push rod 60 mounted on the base 10.

[0034] The electromagnetic push rod 60 has a sliding telescopic end 61 that is assembled and connected to the moving part 40, so that during the sliding telescopic process, the sliding telescopic end 61, through the moving part 40, drives the blocking part 30 to rotate to the blocking position where the blocking hook 20 rotates (see...). Figure 8 (as shown), or, during the sliding telescopic process, the sliding telescopic end 61, through the moving part 40, drives the blocking part 30 to rotate to the release position where it disengages from the blocking lock hook 20 (see...). Figure 9 (As shown); Alternatively, as an example, the sliding extension end 61 of the electromagnetic push rod 60 retracts when the electromagnetic push rod 60 is energized, thereby driving the moving member 40 to slide in the opposite direction indicated by arrow A. This, in turn, causes the blocking member 30 to rotate around its rotation center line 31, via the moving member 40 sliding in the opposite direction of arrow A. Figure 8 Rotate to the indicated blocking position Figure 9 The release position shown allows the locking hook 20 to be released from its position. Figure 8 and Figure 9 The locked position shown is towards Figure 10 The lock release position switch shown is to satisfy the locked object 200 (see...) Figure 11 and Figure 12 The need to move the electronic bumper lock 100 in the trunk of the car according to the first embodiment is not met; conversely, when the electromagnetic push rod 60 is de-energized, the sliding extension end 61 of the electromagnetic push rod 60 extends and slides with the help of the return spring 62 of the electromagnetic push rod 60, thereby driving the moving member 40 to slide in the direction indicated by arrow A by the extended sliding extension end 61, thereby the moving member 40 sliding in the direction indicated by arrow A is linked to the blocking member 30 around its rotation center line 31. Figure 10 Rotate to the indicated release position Figure 7 and Figure 8 The blocking position shown indicates that the blocking hook 20 is... Figure 8 and Figure 9 The locked position shown is towards Figure 10 The shown unlocking position switching is used to achieve the purpose of locking the locked object 200 with the cooperation of the locking hook 20 and the base 10. The status is shown in the figure. Figure 12 As shown.

[0035] The traction component 50 can be linked to the blocking component 30 by the moving component 40. Figure 8 Rotate to the indicated blocking position Figure 10 The release position shown can be, for example, a rope for the traction member 50 to facilitate its winding operation; obviously, the traction member 50 can also be other slender structures with traction function, depending on actual needs.

[0036] The locking hook 20 can be rotated to a locked position where it locks the object 200 together with the base 10 (see...). Figure 7 and Figure 8 Alternatively, the locking hook 20 can be rotated to the unlocking position to release the locked object 200 (see...). Figure 10 Therefore, when the blocking member 30 rotates to the blocking position, the blocking member 30 blocks the locking hook 20. Figure 9 The lock position shown and Figure 10 Switching between the shown unlock positions. Specifically, at Figures 1 to 4In this example, the base 10 includes a housing 11 and a frame 12 stacked and fixed together in the direction of the rotation center line 31 of the blocking member 30 (see double arrow B). Alternatively, as an example, the frame 12 can be formed by ultrasonic welding of multiple sheet metal pieces to eliminate the need for fasteners, thereby making the volume of the electronic bumper lock 100 for the trunk of the first embodiment smaller. In addition, the blocking member 30 and the lock hook 20 are assembled in the frame 12. The blocking member 30 is provided with a linkage post 32 extending in the direction of the rotation center line 31 of the blocking member 30 and partially extending into the housing 11. The housing 11 has an opening for the linkage post 32 to extend into and to provide protection for the linkage post 32 that rotates with the blocking member 30. The clearance through-hole 111 is preferably arc-shaped around the rotation center line 31 of the blocking member 30, so that the fitting clearance between the connecting column 32 and the clearance through-hole 111 is kept as consistent as possible, creating favorable conditions for effectively reducing the exposure of the moving member 40 and the electromagnetic push rod 60. The moving member 40 and the electromagnetic push rod 60 are assembled inside the housing 11, and the moving member 40 has a connecting groove 41 that mates with the connecting column 32. At this time, the traction member 50 extends out of the housing 11. Therefore, the housing 11 covers the moving member 40 and the electromagnetic push rod 60, effectively reducing the position of the moving member 40 and the electromagnetic push rod 60 exposed on the base 10, thereby better protecting the moving member 40 and the electromagnetic push rod 60. More specifically, see the description below.

[0037] like Figures 2 to 4 As shown, as an example, the electronic trunk lock 100 of the first embodiment also includes a locking hook 20 for... Figure 9 The locked position shown is towards Figure 10 The return spring 70, which rotates to the unlocked position, is located on both the lock hook 20 and the frame rib 12. Therefore, the return spring 70 ensures that the lock hook 20 is in the position indicated by the blocking member 30. Figure 9 When the release position is shown, it can automatically move to... Figure 10 The locking and unlocking position is switched to facilitate the movement of the locked object 200 into or out of the partition limiting hole 23, as described below. Specifically, in Figures 2 to 4 In this example, the return spring 70 is a torsion spring, which better meets the need for the lock hook 20 to rotate and return to its original position.

[0038] like Figures 1 to 2 and Figures 3 to 10As shown, as an example, the blocking member 30 and the locking hook 20 are arranged sequentially along the extension direction of the sliding telescopic end 61 (see arrow A). The moving member 40 is spaced apart from the blocking member 30 in the direction of the rotation center line 31 of the blocking member 30. For example, in the direction of the rotation center line 31 of the blocking member 30, the blocking member 30 and the locking hook 20 are arranged on the same layer, and the moving member 40 and the electromagnetic push rod 60 are arranged on the same layer. This design makes the arrangement of the blocking member 30, the locking hook 30 and the moving member 40 on the base 10 more compact. Furthermore, regarding... Figure 2 and Figure 3 In this example, the blocking member 30 and the locking hook 20 are each a sheet-like structure, making both the blocking member 30 and the locking hook 20 thinner in the direction of the rotation center line 31 of the blocking member 30. This creates favorable conditions for making the electronic bumper lock 100 for the trunk of the car in the first embodiment thinner. Furthermore, in... Figures 2 to 10 As an example, the lock hook 20 has a partition limiting hole 23, which also penetrates the periphery 20a of one side of the lock hook 20. Alternatively, as an example, the entrance 231 of the partition limiting hole 23 is along the penetrating direction of the partition limiting hole 23 (see...). Figure 10 The angled arrangement (indicated by the dashed arrow) facilitates the entry and exit of the locked object 200 through the partition limiting hole 23. Obviously, depending on actual needs, the entrance 231 of the partition limiting hole 23 can also be other shapes well-known in the art; therefore, it is not specified... Figures 2 to 10 The diagram shows the limit; however, the frame 12 is provided with an avoidance channel 121, which overlaps with the partition limit hole 231 when the locking hook 20 rotates to the locked position, as shown in the diagram. Figure 5 and Figure 6 As shown; when the locking hook 20 rotates to the release position, the clearance channel 121 is misaligned with the separating limiting hole 231, as shown in the figure. Figure 7 As shown.

[0039] like Figures 1 to 10 As shown, as an example, the linkage column 32 is located at the end 30a of the blocking member 30, away from the rotation center line 31 of the blocking member 30, which makes it easier for the moving member 40 to rotate in conjunction with the blocking member 30, improving the smoothness and reliability of the linkage. Furthermore, in Figures 2 to 3 and Figures 8 to 10 As an example, the blocking member 30 has a recessed structure 33 on the side facing the locking hook 20, and the locking hook 20 has a protruding structure 21 on the side facing the blocking member 30, so that the blocking member 30 can be disengaged from or blocked by the locking hook 20 by the engagement and disengagement of the protruding structure 21 and the recessed structure 33; alternatively, in Figures 8 to 10In this example, the periphery of the blocking member 30 has a first arcuate profile 34 extending arcuately around the rotation center line 31 of the blocking member 30 and facing the locking hook 20. The periphery 20a of the locking hook 20 has a second arcuate profile 22 extending arcuately around the rotation center line 31 of the blocking member 30 and facing the first arcuate profile 34, so that the locking hook 20 and the blocking member 30 can be made closer together. The periphery of the protrusion structure 21 on the locking hook 20 has a third arcuate profile 211 tangent to the second arcuate profile 22 and protruding in the opposite direction, a straight profile 212 opposite to the third arcuate profile 211, and an arcuate transition profile 213 connecting the third arcuate profile 211 and the straight profile 212, so that when the locked object 200 enters the locking hook 20 in the release position and drives the locking hook 20 to switch to the locking position around the rotation center line 24 of the locking hook 20, for example, in Figure 11 When the locking hook 20 rotates clockwise, the protruding structure 21 of the locking hook 20, with the help of the third arc-shaped contour 211 and the arc-shaped transition contour 213, pushes the blocking member 30 to the position where it locks with the recessed structure 32. Therefore, the locking hook 20 is... Figure 10 The release position shown is towards Figure 9 The shown lock position switching operation is more convenient. It should be noted that, although... Figures 8 to 10 The diagram shows that the protruding structure 21 is provided by the locking hook 20, while the recessed structure 32 is provided by the blocking member 30. Obviously, depending on actual needs, the locking hook 20 can also have a recessed structure, and the blocking member 30 can have a protruding structure. Therefore, it is not necessary to specify the specific structure. Figures 8 to 10 The above is the limit.

[0040] Please see Figure 13 The second embodiment of the electronic trunk lock 100 is basically the same as the first embodiment of the electronic trunk lock 100, the only difference being the orientation of the obstacle avoidance passage 121. Specifically, in Figure 13 In the second embodiment, the obstacle avoidance passage 121 in the electronic bumper lock 100' of the car trunk is arranged forward, while... Figure 1 In the first embodiment, the clearance passage 121 of the electronic trunk lock 100' is arranged rearward; so that one of the electronic trunk lock 100' of the second embodiment and the electronic trunk lock 100' of the first embodiment is suitable for installation on the left side, and the other is suitable for installation on the right side.

[0041] Please see Figure 14The third embodiment of the electronic trunk lock 100' is basically the same as the first embodiment of the electronic trunk lock 100, except that the former has a mounting bracket 122 bent out from the frame 12 and arranged side by side with the housing 11 at a distance. The mounting bracket 122 also extends along the sliding extension direction of the sliding extension end 61 (see the direction indicated by arrow A and the opposite direction), so that the third embodiment of the electronic trunk lock 100' can be assembled on the corresponding position of the car with the help of the mounting bracket 122. In the first embodiment of the electronic trunk lock 100, its frame 12 is not bent with the mounting bracket 122, so the first embodiment of the electronic trunk lock 100 can be assembled on the corresponding position of the car with the help of the frame 12.

[0042] Apart from the differences mentioned above, the two are the same, so they will not be repeated here.

[0043] Please see Figure 15 The electronic trunk lock 100 in the fourth embodiment is basically the same as the electronic trunk lock 100 in the third embodiment, except that the obstacle avoidance passage 121 is oriented differently. Specifically, in Figure 15 In the fourth embodiment, the obstacle avoidance passage 121 in the electronic bumper lock 100 of the car trunk is arranged forward, while... Figure 14 In the third embodiment, the clearance passage 121 in the electronic trunk lock 100'' of the car is arranged rearward; so that one of the electronic trunk lock 100''' of the fourth embodiment and the electronic trunk lock 100'' of the third embodiment is suitable for installation on the left side, while the other is suitable for installation on the right side.

[0044] Compared with the prior art, the electromagnetic push rod 60 has a sliding telescopic end 61 that is assembled and connected to the moving part 40. During the sliding telescopic process, the sliding telescopic end 61 is connected to the moving part 40 to rotate the blocking part 30 to the blocking position of the blocking hook 20 or to the releasing position of the blocking hook 20. The traction part 50 can be connected to the moving part 40 to rotate the blocking part 30 from the blocking position to the releasing position. This design allows the user to rotate the blocking part 30 to the unlocking position by electric drive or manual means, thereby allowing the locking hook 20 to unlock the locked object 200. Furthermore, since the electromagnetic push rod 60 or the traction part 50 is connected to the blocking part 30 to rotate from the blocking position to the releasing position by the moving part 40, the moving part 40 and the electromagnetic push rod 60 can be hidden in the base 10, reducing the exposure of the moving part 40 and the electromagnetic push rod 60, thereby protecting the moving part 40 and the electromagnetic push rod 60.

[0045] It should be further noted that the aforementioned housing 11 is a composite structure of nylon and fiber materials, giving it the advantages of high temperature resistance and aging resistance. Furthermore, the frame 12 can be constructed from multiple sheet metal pieces welded together using ultrasonic welding, eliminating the need for screws and saving space, allowing the base 10 to be made smaller. In addition, the frame 12 is made of low-carbon steel, the hook lock 20 is made of high-strength steel, and the blocking component 30 is made of high-strength steel, giving the hook lock 20 and the blocking component 30 the advantages of resistance to high salt spray, radiation protection, and ultraviolet radiation protection. Finally, the more specific structure and working principle of the electromagnetic push rod 60 are well known in the art and will not be described in detail here.

[0046] The above-disclosed examples are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Therefore, any equivalent variations made in accordance with the claims of the present utility model shall fall within the scope of the present utility model.
