Description

Technical Field

[0001] This utility model relates to the field of clock spring technology, and in particular to a locking structure for a clock spring. Background Art

[0002] In existing technology, a clock spring is a device used to connect the main airbag to the airbag wiring harness, also known as an airbag clock spring. It is typically wound around the steering wheel shaft, loosening or tightening as the steering wheel rotates to ensure the wiring harness does not break when the steering wheel is turned. The clock spring is designed to remain safe even at the steering wheel's extreme turning positions; therefore, special care is needed during installation to ensure it is in the center position to avoid overstretching. In existing technology, if the clock spring lacks locking during use, it will rotate excessively, potentially causing internal wiring breakage and affecting its operation.

[0003] Therefore, this application proposes a locking structure for a clock spring to solve the above-mentioned problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing clock springs, where excessive rotation can occur if there is no locking mechanism, leading to internal circuit breakage and affecting usability. This invention proposes a locking structure for clock springs.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A locking structure for a clock spring includes a housing and a clock spring;

[0009] A control ring, which is fixedly connected to the front side of the housing;

[0010] A hollow locking plate is fixedly connected to the top of the clock spring;

[0011] Two clamping plates are fixedly connected to the rear side of the clock spring;

[0012] A locking mechanism includes an auxiliary plate, a push plate, a hollow plate, a connecting plate, an extension plate, and a positioning plate.

[0033] Two clamping plates 19 are fixedly connected to the rear side of the clock spring 14;

[0034] The locking mechanism includes an auxiliary plate 7, a push plate 8, a hollow plate 9, a connecting plate 10, an extension plate 11, and a positioning plate 13. The auxiliary plate 7 is slidably connected to the rear inner wall of the control box 2. The push plate 8 is rotatably connected to the front side of the auxiliary plate 7. The hollow plate 9 is slidably connected to the bottom inner wall of the control box 2, and the front side of the hollow plate 9 is rotatably connected to the right side of the push plate 8. The connecting plate 10 is rotatably connected to the front side of the hollow plate 9. The extension plate 11 is slidably connected to the rear inner wall of the control box 2, and the bottom of the extension plate 11 is rotatably connected to the top of the connecting plate 10. The top of the extension plate 11 extends to the outside of the control box 2. The positioning plate 13 is fixedly connected to the top of the extension plate 11.

[0035] With the above structure: by setting up a movable plate 4, the movable plate 4 moves with the movement of button 3, which facilitates the movement of the auxiliary plate 7; by setting up a control ring 16, the control ring 16 plays the role of assisting the locking plate 15 to pass through; by setting up a clamping plate 19, the clamping plate 19 plays the role of initially controlling the connection between the clock spring 14 and the outer shell 1.

[0036] As a preferred embodiment of this utility model, the locking plate 15 is provided with a positioning hole, and the positioning plate 13 is movably connected to the positioning hole. When the positioning plate 13 passes through the positioning hole, the positioning plate 13 can fix the locking plate 15.

[0037] As a preferred embodiment of this utility model, a limiting plate 17 is slidably connected inside the hollow plate 9, and a limiting hole is provided at the bottom of the control box 2. The limiting plate 17 is movably connected to the limiting hole. By setting the limiting plate 17 and connecting the limiting plate 17 to the limiting hole, the entire device is locked.

[0039] As a preferred embodiment of this utility model, two rotating columns 5 are rotatably connected to the rear inner wall of the control box 2. The outer walls of the two rotating columns 5 are fitted with the same transmission belt 6. The outer wall of the transmission belt 6 is fixedly connected to the right side of the movable plate 4 and the left side of the auxiliary plate 7. When the movable plate 4 moves, the movable plate 4 controls the transmission belt 6 to rotate, thereby synchronously controlling the auxiliary plate 7 to rise.

[0040] As a preferred embodiment of this utility model, a second spring 18 is fixedly connected to the bottom of the limiting plate 17, and one end of the second spring 18 is fixedly connected to the top of the hollow plate 9. By setting the second spring 18, the second spring 18 is initially in a stretched state, which facilitates pulling the limiting plate 17 down.

[0041] It should be noted that the specific model of clock spring 14 used is to be selected by those skilled in the art, and the above-mentioned clock spring 14 is existing technology, so this solution will not elaborate on it.

[0042] The working principle of this utility model is as follows: In actual operation, the clock spring 14 connected to the clamping plate 19 is inserted into the outer shell 1, and the clamping plate 19 passes through the outer shell 1 for fixation. At the same time, the locking plate 15 passes through the control ring 16. At this time, pressing the button 3 lowers the plate 4, which in turn controls the transmission belt 6 to rotate. The transmission belt 6 then synchronously controls the auxiliary plate 7 to rise. As the auxiliary plate 7 moves, it pushes the push plate 8 to move, and the movement of the push plate 8 pushes the hollow plate 9 to the right. When the hollow plate 9 moves, it can push the connecting plate 10, thereby pushing the extension plate 11 to rise. When the extension plate 11 moves, it can push the positioning plate 13 to rise. At this time, the positioning plate 13 passes through the locking plate 15 and fixes the locking plate 15, thereby positioning the clock spring 14. At the same time, the movement of the hollow plate 9 drives the movement of the limiting plate 17. The limiting plate 17 descends through the second spring 18 and connects with the limiting hole to lock the entire device and ensure the stability of the clock spring 14.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto.
