Description
Technical Field
[0001] This application relates to the field of automotive seat unlocking switch technology, specifically a highly stable automotive seat unlocking switch. Background Technology
[0002] The car seat unlock switch is a crucial component of the car seat adjustment system, and its stability and reliability directly impact the user experience and safety of the seat. Currently, the design of car seat unlock switches mainly focuses on the structure and operation method of the unlocking handle, with common unlock switches including button-type, lever-type, and rotary types. As car seat functions become more diverse, users have increasingly higher demands for the ease of operation and stability of the unlock switches.
[0003] Existing unlock switches typically require continuous force from the user to maintain the unlocked state, which not only increases the user's workload but also poses a safety hazard due to misoperation. Utility Model Content
[0004] To address the shortcomings of existing technologies, this application provides a highly stable car seat unlocking switch. This switch features a stable, limited unlocking handle in the unlocked state, eliminating the need for continuous pulling by the user and saving operational effort. It also offers high stability in the unlocked state, preventing the unlocking handle from resetting due to torsion springs or other reset components, thus improving the safety of seat use. This solves the problem that existing unlocking switches typically require continuous force from the user to maintain the unlocked state, which not only increases the user's operational burden but also poses safety hazards due to misoperation.
[0005] To achieve the aforementioned goal of ensuring the unlocking handle is stably limited in the unlocked state, eliminating the need for continuous pulling by the user, saving operational effort, ensuring high stability in the unlocked state, and preventing the unlocking handle from resetting due to torsion springs or other reset components, thereby improving the safety of seat use, this application provides the following technical solution: A high-stability car seat unlocking switch, comprising a switch body, an unlocking shaft inside the switch body extending to the outside of the switch body, an unlocking component at the end of the unlocking shaft away from the switch body, the unlocking component including a rotating disk, the middle of one side of the rotating disk being located at one end of the unlocking shaft, a handle on one side of the outer surface of the middle of the rotating disk, a limiting plate between the handle and the switch body, a limiting hole on the side of the limiting plate near the switch body, a limiting stop bar on the side of the switch body near the handle, one end of the outer surface of the limiting stop bar being slidably connected to the inner wall of the middle of the limiting hole, the limiting stop bar being located on the movement trajectory of the limiting hole, and a torsion spring between the unlocking shaft and the switch body.
[0006] The above solution involves rotating the handle to make the rotating disk rotate, which in turn moves the limiting plate and moves the limiting hole to the limiting stop. The limiting hole fits onto one end of the limiting stop, restricting the position of the handle and keeping the unlocking component in the unlocked state. This achieves the effect of stably limiting the unlocking handle in the unlocked state, eliminating the need for continuous pulling by the user, saving operating force, ensuring high stability in the unlocked state, and preventing the unlocking handle from resetting due to torsion springs or other reset components, thus improving the safety of seat use.
[0007] Furthermore, a first protective cover is provided on the side of the rotating disk near the switch body. The end of the first protective cover away from the rotating disk is slidably connected to the outer surface of one side of the switch body. The first protective cover is located outside the unlocking shaft and the torsion spring.
[0008] The above solution uses a first protective cover to shield the unlocking shaft and torsion spring, preventing interior components inside the vehicle from getting tangled in them.
[0009] Furthermore, the edge of the limiting plate near the limiting stop is chamfered, and the edge of the limiting hole entrance on one side of the limiting plate is chamfered.
[0010] The above solution utilizes a chamfered angle on the edge of the limiting plate near the limiting stop bar. This allows the limiting stop bar to push the limiting plate against the chamfered edge, preventing the limiting plate from being blocked by the limiting stop bar. This allows the limiting hole to move smoothly to the position aligned with the limiting stop bar. The chamfered angle at the entrance edge of the limiting hole guides the limiting hole as it fits onto the outer surface of one end of the limiting stop bar, ensuring a smooth fit.
[0011] Furthermore, one side of the limiting plate is disposed at one end of the connecting rod, and the outer surface of the middle part of the connecting rod is slidably disposed within the inner wall of one side of the handle.
[0012] The above solution allows the limiting plate to be fixed along the trajectory of the handle's movement by sliding the middle outer surface of the connecting rod within the inner wall of one side of the handle, thereby improving the stability of the limiting plate and the connecting rod when moving with the handle.
[0013] Furthermore, one end of the connecting rod is hinged to a swing rod via a hinge frame, the end of the swing rod away from the connecting rod is hinged to one end of the push rod via the hinge frame, and the other end of the push rod extends to the outside of one end of the handle.
[0014] With the above scheme, the connecting rod can slide inside the inner wall of one side of the handle to drive the swing rod to swing, so that the swing rod drives the push rod to move linearly. Furthermore, the push rod can be operated in conjunction with the connecting rod to drive the limit plate to move, thereby adjusting the position between the limit hole and one end of the limit stop rod.
[0015] Furthermore, a fixing plate is provided on the outer surface of the middle part of the push rod, a spring is provided on one side of the fixing plate, the end of the spring away from the fixing plate is provided on one side of the positioning plate, and the two ends of the positioning plate are provided on both sides of the inner wall of the middle part of the handle.
[0016] With the above scheme, the spring can apply a pushing force to the fixed plate, which in turn pushes the push rod to reset. The push rod then drives the connecting rod to reset via the swing rod, which in turn pushes the limiting plate to reset. This allows the limiting hole to be fitted onto the outer surface of one end of the limiting stop rod.
[0017] Furthermore, the outer surface of the middle part of the push rod is slidably disposed within the inner wall of the middle part of the positioning plate, and the outer surface of the middle part of the push rod is quadrilateral, the shape of the outer surface of the middle part of the push rod being adapted to the shape of the inner wall of the middle part of the positioning plate.
[0018] The above scheme allows the push rod to slide within the inner wall of the positioning plate at its center by its outer surface. The shape of the outer surface of the push rod at its center restricts the trajectory and angle of the push rod's movement, thereby improving the stability of the push rod's movement.
[0019] Furthermore, one end of the push rod is provided with an arc-shaped plate, one side of the arc-shaped plate is provided at one end of the inner wall of the second protective cover, the second protective cover is provided at one end of the handle, and the second protective cover is made of deformable rubber material.
[0020] The above solution increases the operating area at one end of the push rod by setting the arc plate, thereby improving the convenience and comfort of pushing the push rod. The second protective cover protects the arc plate and push rod when they are pushed, preventing the operator from being squeezed by the arc plate. At the same time, the second protective cover can deform when the arc plate is pushed, so as not to affect the movement of the arc plate.
[0021] Compared with the prior art, the technical solution of this application has the following beneficial effects:
[0022] This highly stable car seat unlocking switch, by pulling the handle, causes the rotating disc to rotate, which in turn moves the limiting plate, causing the limiting hole to move to the limiting stop bar. The limiting hole fits onto one end of the limiting stop bar, restricting the position of the handle and keeping the unlocking component in the unlocked state. This achieves stable limiting of the unlocking handle in the unlocked state, eliminating the need for continuous pulling by the user, saving operating force, and providing high stability in the unlocked state. It also avoids the unlocking handle resetting due to torsion springs or other reset components, thus improving the safety of seat use. Attached Figure Description

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0032] Please see Figure 1 , Figure 2 and Figure 4 This embodiment of a high-stability car seat unlocking switch includes a switch body 1, an unlocking shaft 2 inside the switch body 1, the unlocking shaft 2 extending to the outside of the switch body 1, an unlocking component 3 at the end of the unlocking shaft 2 away from the switch body 1, the unlocking component 3 including a rotating disk 301, the middle of one side of the rotating disk 301 being located at one end of the unlocking shaft 2, a handle 302 on one side of the outer surface of the middle of the rotating disk 301, a limiting plate 5 between the handle 302 and the switch body 1, a limiting hole 6 on the side of the limiting plate 5 near the switch body 1, a limiting stop bar 7 on the side of the switch body 1 near the handle 302, one end of the outer surface of the limiting stop bar 7 being slidably connected to the inner wall of the middle of the limiting hole 6, the limiting stop bar 7 being located on the movement trajectory of the limiting hole 6, and a torsion spring 8 between the unlocking shaft 2 and the switch body 1.
[0033] Please see Figure 1 , Figure 2 and Figure 4A first protective cover 9 is provided on the side of the rotating disk 301 near the switch body 1. The end of the first protective cover 9 away from the rotating disk 301 is slidably connected to the outer surface of one side of the switch body 1. The first protective cover 9 is located outside the unlocking shaft 2 and the torsion spring 8. The first protective cover 9 can shield the unlocking shaft 2 and the torsion spring 8, preventing the interior components inside the vehicle from being entangled by the unlocking shaft 2 and the torsion spring 8.
[0034] Please see Figure 2 , Figure 4 and Figure 5 The edge of the limiting plate 5 near the limiting rod 7 is chamfered, and the edge of the entrance to the limiting hole 6 on one side of the limiting plate 5 is also chamfered. The chamfer on the edge of the limiting plate 5 near the limiting rod 7 allows the limiting rod 7 to push the limiting plate 5, preventing the movement of the limiting plate 5 from being blocked by the limiting rod 7. This allows the limiting hole 6 to move smoothly to the position aligned with the limiting rod 7. The chamfer at the entrance of the limiting hole 6 guides the limiting hole 6 when it is fitted onto the outer surface of one end of the limiting rod 7, ensuring that the limiting hole 6 fits smoothly onto the outer surface of one end of the limiting rod 7.
[0035] Please see Figure 2 and Figure 4 One side of the limiting plate 5 is disposed at one end of the connecting rod 4, and the outer surface of the middle part of the connecting rod 4 is slidably disposed within the inner wall of one side of the handle 302. By sliding the outer surface of the middle part of the connecting rod 4 within the inner wall of one side of the handle 302, the trajectory of the limiting plate 5 based on the movement of the handle 302 can be fixed, thereby improving the stability of the limiting plate 5 and the connecting rod 4 when moving based on the handle 302.
[0036] Please see Figure 3 , Figure 4 and Figure 6 One end of the connecting rod 4 is hinged to a swing rod 10 via a hinge frame. The end of the swing rod 10 away from the connecting rod 4 is hinged to one end of the push rod 11 via the hinge frame. The other end of the push rod 11 extends to the outside of one end of the handle 302. By sliding the connecting rod 4 on the inner wall of one side of the handle 302, the swing rod 10 can be driven to swing, so that the swing rod 10 drives the push rod 11 to move linearly. Furthermore, by operating the push rod 11 in conjunction with the connecting rod 4, the limiting plate 5 can be moved, adjusting the position between the limiting hole 6 and one end of the limiting stop rod 7.
[0037] Please see Figure 3 , Figure 4 and Figure 6A fixing plate 12 is provided on the outer surface of the middle part of the push rod 11. A spring 14 is provided on one side of the fixing plate 12. The end of the spring 14 away from the fixing plate 12 is provided on one side of the positioning plate 13. The two ends of the positioning plate 13 are provided on both sides of the inner wall of the middle part of the handle 302. The spring 14 can apply a pushing force to the fixing plate 12, and then push the push rod 11 to reset through the fixing plate 12. The push rod 11 drives the connecting rod 4 to reset through the swing rod 10, and the connecting rod 4 pushes the limiting plate 5 to reset. Then the limiting hole 6 can be pushed to fit on the outer surface of one end of the limiting stop rod 7.
[0038] Please see Figure 3 , Figure 4 and Figure 6 The outer surface of the middle part of the push rod 11 is slidably disposed within the inner wall of the middle part of the positioning plate 13. The outer surface of the middle part of the push rod 11 is quadrilateral, and the shape of the outer surface of the middle part of the push rod 11 is adapted to the shape of the inner wall of the middle part of the positioning plate 13. By sliding the outer surface of the middle part of the push rod 11 within the inner wall of the middle part of the positioning plate 13, the shape of the outer surface of the middle part of the push rod 11 can limit the trajectory and angle of the push rod 11 during movement, thereby improving the stability of the push rod 11 during movement.
[0039] Please see Figure 1 , Figure 3 and Figure 5 An arc-shaped plate 15 is provided at one end of the push rod 11. One side of the arc-shaped plate 15 is located at one end of the inner wall of the second protective cover 16. The second protective cover 16 is located at one end of the handle 302. The second protective cover 16 is made of deformable rubber. The arc-shaped plate 15 increases the operating area of one end of the push rod 11, thereby improving the convenience and comfort of pushing the push rod 11. The second protective cover 16 protects the arc-shaped plate 15 and the push rod 11 when they are pushed, preventing the operator from being squeezed by the arc-shaped plate 15. At the same time, the second protective cover 16 can deform when the arc-shaped plate 15 is pushed, so as not to affect the movement of the arc-shaped plate 15.
[0040] This embodiment provides a high-stability car seat unlocking switch. By pulling the handle 302, the rotating disk 301 rotates, causing the limiting plate 5 to move. This moves the limiting hole 6 to the limiting stop 7, where the limiting hole 6 fits onto one end of the limiting stop 7, thus restricting the position of the handle 302. This keeps the unlocking component 3 in the unlocked state, achieving stable limiting of the unlocking handle in the unlocked state. It eliminates the need for continuous pulling by the user, saving operating force. The unlocked state is highly stable, preventing the unlocking handle from resetting due to torsion springs or other reset components, thereby improving the safety of seat use.
[0041] The working principle of the above embodiment is as follows: In the locked state, the handle 302 is in the initial position. Pulling the handle 302 causes it to swing, which in turn drives the rotating disk 301 to rotate. The rotating disk 301 then drives the unlocking shaft 2 to rotate. When the handle 302 swings, it causes the limiting plate 5 to move towards the limiting stop 7, so that the chamfered edge of one side of the limiting plate 5 contacts one end of the limiting stop 7. The limiting stop 7 then pushes the limiting plate 5 through the chamfered edge of one side of the limiting plate 5, pushing the limiting plate 5 towards the handle 302. The connecting rod 4 moves, causing the swing rod 10 to swing. During this swing, the swing rod 10 drives the push rod 11 to slide within the inner wall of the positioning plate 13. As the push rod 11 moves, it compresses the spring 14 via the fixing plate 12. The movement of the limiting plate 5 allows it to swing smoothly with the handle 302. The continuous swinging of the handle 302 moves the limiting hole 6 to a position aligned with one end of the limiting stop rod 7. Simultaneously, this continuously drives the unlocking shaft 2 to rotate, causing the switch body 1 to enter the unlocking position. In the locked state, spring 14 releases its thrust, pushing push rod 11 to reset via fixed plate 12. Push rod 11 then drives swing rod 10 to swing and reset. As swing rod 10 swings, it pushes connecting rod 4 to move, causing connecting rod 4 to move limiting plate 5 to reset. When limiting plate 5 moves, it causes limiting hole 6 to fit onto the outer surface of one end of limiting stop rod 7, thus fixing the position of handle 302 by limiting hole 6 and limiting stop rod 7. This keeps switch body 1 in the unlocked state. When it is necessary to restore the locked state, the second protection... Cover 16 pushes the arc plate 15 to move towards the handle 302, causing the arc plate 15 to drive the push rod 11 to slide within the inner wall of the middle part of the positioning plate 13. This causes the push rod 11 to drive the swing rod 10 to swing, which in turn causes the swing rod 10 to move the connecting rod 4. When the connecting rod 4 moves, it will drive the limiting plate 5 to move towards the handle 302, causing the limiting hole 6 to slide off the outer surface of one end of the limiting stop rod 7. This releases the limitation of the limiting stop rod 7 on the position of the handle 302 through the limiting hole 6, pushes the handle 302 to swing back to its original position, and thus restores the locked state.
