[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 - Figure 3 The utility model provides an embodiment: a steering wheel clock spring based on a carbon brush electrode, comprising a lower shell 1, a plurality of mounting shells 2 are fixedly connected to the inner wall of the lower shell 1, an electrode block 3 is fixedly connected to the bottom of the inner wall of the lower shell 1, a plurality of mounting shells 2 are fixedly connected to the inner walls of the plurality of mounting shells 2 are fixedly connected to buffer blocks 4, a spring 5 is fixedly connected to the other side of the inner wall of the mounting shell 2, a clamping plate 6 is fixedly connected to one end of the spring 5, one side of the outer wall of the clamping plate 6 is in contact with one side of the outer wall of the electrode block 3, and an upper cover 7 is slidably connected to the upper surface of the mounting shell 2, A snap-fit ​​assembly 8 is provided on one side of the outer wall of the upper cover 7, a plurality of snap-fit ​​blocks 9 are fixedly connected to the inner wall of the lower shell 1, an upper shell 10 is slidably connected to the upper surface of the lower shell 1, a plurality of protrusions 11 are fixedly connected to one side of the inner wall of the upper shell 10, and the snap-fit ​​blocks 9 are snap-fitted with the protrusions 11; the snap-fit ​​assembly 8 includes a snap 801, one side of the outer wall of the snap 801 is fixedly connected to one side of the outer wall of the upper cover 7, a snap-fit ​​block 1 802 is snap-fitted inside the snap 801, and one side of the outer wall of the snap block 1 802 is fixedly connected to one side of the outer wall of the mounting shell 2;

[0025] Specifically, by installing the electrode block 3 on the inner wall of the mounting shell 2, with the help of the reaction force of the second spring 15, the electrode block 3 is pushed to contact the outer wall of the buffer block 4. In this step, the design inside the clock spring allows one to three loops to facilitate adjustment and adaption to different needs. Subsequently, the outer wall buckle 801 of the upper cover 7 engages with the outer wall of the block one 802, thereby ensuring that the electrode block 3 is firmly fixed and preventing it from accidentally falling off. Finally, the upper shell 10 covers the top of the lower shell 1, and the protrusion 11 engages with the block two 9 to ensure that the upper shell 10 is firmly fixed. This design simplifies the assembly process and improves the fixation of the components, while ensuring the stability and reliability of the overall structure;

[0026] Reference Figure 4 , Figure 5 , a plurality of fixed boxes 12 are fixedly connected to one side of the outer wall of the lower shell body 1, and a through hole 13 is opened inside the fixed box 12; a mounting rod 14 is slidably connected inside the fixed box 12, and the outer wall of the mounting rod 14 is slidably connected to the inner wall of the through hole 13; a plurality of springs 15 are fixedly connected to the top of the inner wall of the fixed box 12, and a sliding plate 16 is fixedly connected to one end of the spring 15; the outer wall of the sliding plate 16 is slidably connected to the inner wall of the fixed box 12, and a support rod 17 is fixedly connected to the lower surface of the sliding plate 16; the inner wall of the support rod 17 is rotatably connected to a connecting rod 18, and one side of the inner wall of the connecting rod 18 is rotatably connected to the inner wall of the connecting rod 2 19, and one side of the connecting rod 2 19 is rotatably connected to the inner wall of the fixed box 12; the outer wall of the connecting rod 2 19 is rotatably connected to a hinge seat 20, and a block 3 21 is fixedly connected to one side of the outer wall of the hinge seat 20, and the outer wall of the block 3 21 is slidably connected to the inside of the fixed box 12;

[0027] Specifically, when the fixed box 12 is inserted into the outer wall of the mounting rod 14, the connecting rod 18 is pushed to rotate by the resistance of the block 3 21. This rotation process is crucial because it drives the sliding plate 16 on the upper surface of the support rod 17 to slide. This sliding mode makes it possible to achieve the contraction of the spring 2 15. When the spring 2 15 is driven to contract, it will generate a reaction force to push the sliding plate 16 to move in the opposite direction. As a result of this reverse movement, the block 3 21 can be easily engaged into the interior of the mounting rod 14. This process greatly improves the efficiency of installation and disassembly, saving time and energy. The user only needs to pull the handle on the outer wall of the sliding plate 16 by hand to quickly disassemble the fixed box 12. This design makes the installation and disassembly process easy and simple, and both professionals and ordinary users can easily complete the operation.

[0028] Working principle: by installing the electrode block 3 on the inner wall of the mounting shell 2, the reaction force of the spring 1 5 pushes the electrode block 3 to contact the outer wall of the buffer block 4. It should be noted that the electrode block 3 can be arranged inside the clock spring of one to three loops. At this time, the buckle 801 of the outer wall of the upper cover 7 is engaged with the outer wall of the block 1 802, so as to achieve the effect of preventing the electrode block 3 from falling off by fixing the upper cover 7. At this time, the upper shell 10 is covered on the top of the lower shell 1, and the protrusion 11 is engaged with the block 2 9, so as to achieve the effect of fixing the upper shell 10.

[0029] Secondly, after the assembly is completed, the fixing box 12 is inserted into the outer wall of the mounting rod 14. At this time, the block three 21 is resisted and pushes the connecting rod 18 to rotate, thereby achieving the effect of driving the sliding plate 16 on the upper surface of the support rod 17 to slide. Through the movement of the sliding plate 16, the spring two 15 is driven to contract. At this time, the sliding plate 16 is pushed by the reaction force of the spring two 15, thereby achieving the effect of facilitating the engagement of the block three 21 into the interior of the mounting rod 14. Conversely, by pulling the handle on the outer wall of the sliding plate 16, the fixing box 12 can be quickly disassembled.

[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
