The combination switch body includes a bracket detachably connected to the column and a clock spring, a light switch, and a wiper switch snapped onto the bracket. The bracket includes a sleeve adapted to fit the column and two snap-fit ​​parts respectively fixed on both sides of the sleeve for mounting the light switch and the wiper switch. A limiting structure is provided between the sleeve and the column to restrict relative rotation between them. A fastening structure is provided on the sleeve for fixing the sleeve onto the column.

[0005] Furthermore, two connecting platforms are provided between the two snap-fit ​​parts. The two connecting platforms are located on both sides of the sleeve. An installation cylinder is provided on the connecting platform. An installation platform corresponding to the installation cylinder is fixed on the column. A countersunk hole is opened on the installation cylinder. The fastening structure includes a fastening bolt that passes through the countersunk hole and is threadedly connected to the installation platform.

[0006] Furthermore, the limiting structure is a boss fixed to the bottom of the mounting cylinder, and the mounting platform has a groove that is compatible with the boss for insertion.

[0007] Furthermore, the sleeve is made of a rigid material with elastic deformation, and multiple deformation grooves are spaced apart along its circumference on the bottom side wall of the sleeve. The openings of the deformation grooves are set away from the sleeve. The fastening structure includes a clamp sleeved on the bottom of the sleeve and a locking bolt for locking the clamp so that the sleeve is tightly clamped to the pipe column.

Detailed Implementation

[0023] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this invention. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0024] Example 1: This application discloses a combination switch integrating dual mounting methods. (Refer to...) Figure 1 , Figure 2 and Figure 3 A combination switch with integrated dual mounting method includes a tube post 1 and a combination switch body mounted on the tube post 1. The combination switch body includes a bracket 5 detachably connected to the tube post 1 and a clock spring 2, a light switch 3, and a wiper switch 4 snapped onto the bracket 5. The clock spring 2 is located above the bracket 5, and the light switch 3 and wiper switch 4 are located on opposite sides of the bracket 5. The bracket 5 includes a sleeve 51 that fits into the tube post 1 and two snap-fit ​​parts 52 respectively fixed on opposite sides of the sleeve 51. Flat plates 22 are provided on both sides of the top of the sleeve 51, and the flat plates 22 are integrally formed with the sleeve 51. The two snap-fit ​​parts 52 are respectively located on the two flat plates 22. The clock spring 2 is snapped onto the flat plate 22 at the top of the sleeve 51. The light switch 3 and wiper switch 4 are snapped onto opposite sides of the sleeve 51 via the snap-fit ​​parts 52. Since the snap-fit ​​installation of the clock spring 2, light switch 3, and wiper switch 4 is prior art, it will not be described in detail here.

[0025] Reference Figure 2 , Figure 3 and Figure 4The two sides of the flat plate 22 are folded downwards and have flanges 23. A connecting platform 6 is provided between the two flanges 23 on the same side of the two flat plates 22. The connecting platform 6 is integrally formed with the flanges 23 of the flat plate 22, so that the two connecting platforms 6 are located on both sides of the sleeve 51. The two connecting platforms 6 and the two flat plates 22 together form an integral structure, which is fixedly sleeved on the top of the sleeve 51, making the installation of the clock spring 2, the light switch 3 and the wiper switch 4 on the sleeve 51 more stable.

[0026] To ensure that sleeve 51 can be smoothly fitted onto pipe string 1, refer to Figure 4 The sleeve 51 is made of a rigid material with elastic deformation, such as polyester elastomer, thermoplastic polyurethane elastomer, polyoxymethylene, etc. Multiple deformation grooves 12 are spaced apart along the circumference of the bottom sidewall of the sleeve 51. The openings of the deformation grooves 12 are positioned away from the sleeve 51, so that during the process of fitting the sleeve 51 onto the tube column 1, the tube column 1 compresses the sidewall of the sleeve 51, and the portion of the sidewall of the sleeve 51 between two adjacent deformation grooves 12 deflects outward, allowing the tube column 1 to be smoothly inserted and installed in the sleeve 51.

[0027] Since both the sleeve 51 and the tubing 1 have circular cross-sections, a limiting structure is provided between them to restrict relative rotation. (Refer to...) Figure 4 and Figure 5 Two sets of limiting structures are provided, symmetrically arranged on both sides of the sleeve 51. The limiting structure includes an elastic plate 15 located in one of the deformation grooves 12 and fixed on the sleeve 51, and a locking block 16 integrally formed on the inner side wall of the elastic plate 15. The elastic plate 15 extends downward along the axial direction of the sleeve 51, and the locking block 16 is located at the bottom of the elastic plate 15. A locking groove 17 adapted to engage with the locking block 16 is provided on the side wall of the tube column 1. Inclined guide surfaces 19 are provided on the inner wall of the bottom of the sleeve 51 and on the inner side wall of the locking block 16 away from the sleeve 51. During the process of inserting the sleeve 51 from the top of the tubing 1, the inclined guide surface 19 allows the sleeve 51 to be smoothly fitted onto the tubing 1. At this time, the side wall portion of the sleeve 51 between the two adjacent deformation grooves 12 and the elastic plate 15 are deflected outwards. The sleeve 51 is pushed downwards until the locking block 16 is aligned with the locking groove 17. At this time, the elastic plate 15 deflects inwards to reset, so that the locking block 16 is engaged in the corresponding locking groove 17. Under the interaction of the locking block 16 and the locking groove 17, the sleeve 51 is not prone to rotation relative to the tubing 1. To prevent the sleeve 51 from continuing to move downwards under force, causing the locking block 16 to move out of the locking groove 17, an abutment ring 18 is provided on the inner wall of the sleeve 51. The abutment ring 18 is located at the end of the sleeve 51 away from the locking block 16. When the locking block 16 is engaged in the locking groove 17, the top of the tubing 1 abuts against the abutment ring 18.

[0028] To further ensure that sleeve 51 can be stably installed on pipe string 1, refer to Figure 2 , Figure 4 and Figure 5 The sleeve 51 is provided with a fastening structure for fixing the sleeve 51 to the tubing column 1. The fastening structure includes a clamp 13 fitted on the bottom of the sleeve 51 and a locking bolt 14 for locking the clamp 13 so that the sleeve 51 is tightly clamped to the tubing column 1. Since the sleeve 51 is provided with a deformation groove 12, when the locking bolt 14 is tightened, the clamp 13 is tightened. Under the action of the clamp 13, the side wall portion of the sleeve 51 between two adjacent deformation grooves 12 deflects inward and abuts against the side wall of the tubing column 1. The inner wall of the sleeve 51 is provided with an anti-slip strip 21. The anti-slip strip 21 can further increase the friction between the tubing column 1 and the sleeve 51, making the connection between the sleeve 51 and the tubing column 1 more stable. To ensure the stability of the clamp 13 when installed on the sleeve 51, a stop block 20 is fixed on the outer wall of the bottom of the sleeve 51 to prevent the clamp 13 from falling off. The stop block 20 can prevent the clamp 13 from slipping off the sleeve 51 after tightening, so that the clamp 13 can always be locked and fitted on the outer periphery of the clamp 13 after tightening. Example 2: The difference between Example 2 and Example 1 lies in the limiting structure and the fastening structure. (Refer to...) Figure 3 , Figure 4 and Figure 6 One of the connecting platforms 6 has an integrally formed mounting cylinder 7 in the middle, and the other connecting platform 6 has two integrally formed mounting cylinders 7, with the two mounting cylinders 7 located on both sides of the connecting platform 6, so that the line connecting the three mounting cylinders 7 can form a stable triangular structure. The mounting cylinders 7 have countersunk holes 9. A mounting seat 24 is detachably installed on the column 1. The mounting seat 24 includes a first seat body 241, a second seat body 242, and connecting bolts 243 for connecting the first seat body 241 and the second seat body 242. Two sets of connecting bolts 243 are provided and are located on both sides of the first seat body 241 and the second seat body 242, respectively. The first seat body 241 and the second seat body 242 are bound together by the connection of the two sets of connecting bolts 243 to form a ring structure, which is stably sleeved on the column 1. A mounting platform 8 protrudes from the first seat body 241, and two mounting platforms 8 protrude from the second seat body 242. The three mounting platforms 8 correspond one-to-one with the three mounting cylinders 7. The fastening structure includes fastening bolts that pass through countersunk holes 9 and are threadedly connected to the mounting platform 8. To prevent the sleeve 51 from deflecting relative to the tubing 1 during the tightening of the fastening bolts, a limiting structure is a boss 10 fixed to the bottom of the mounting cylinder 7. The mounting platform 8 has a groove 11 that is adapted to fit the boss 10. Through the interaction between the boss 10 and the groove 11, the mounting platform 8 is less likely to deflect relative to the mounting cylinder 7 after alignment, ensuring that the fastening bolts can be tightened smoothly.

[0029] The implementation principle of a combination switch integrating dual installation methods according to an embodiment of this application is as follows: In the first installation method, the sleeve 51 is first inserted from the top of the column 1 until the locking block 16 aligns with the locking groove 17 and is locked into the corresponding locking groove 17. At this time, the top of the column 1 is in contact with the abutment ring 18. Next, the clamp 13 is fitted onto the bottom of the sleeve 51 and the locking bolt 14 is tightened, so that the clamp 13 is tightened. Under the action of the clamp 13, the side wall portion of the sleeve 51 between two adjacent deformation grooves 12 deflects inward and abuts against the side wall of the column 1, thereby completing the stable connection between the sleeve 51 and the column 1. Finally, the clock spring 2 is snapped onto the flat plate 22 on the top of the sleeve 51, and the light switch 3 and the wiper switch 4 are snapped onto both sides of the sleeve 51 through the snap-fit ​​part 52.

[0030] In the second installation method, the mounting base 24 is first fixed to the column 1. Then, the three mounting platforms 8 are respectively matched with the three mounting cylinders 7. Next, the sleeve 51 is inserted from the top of the column 1 until the boss 10 is inserted into the corresponding groove 11. At this time, the stop block 20 at the bottom of the sleeve 51 is not in contact with the mounting base 24. Then, the fastening bolts are tightened to make the mounting platform 8 and the mounting cylinder 7 stably connected together, thus completing the stable connection between the sleeve 51 and the column 1. Finally, the clock spring 2 is snapped onto the flat plate 22 on the top of the sleeve 51, and the light switch 3 and the wiper switch 4 are snapped onto both sides of the sleeve 51 through the snap-fit ​​part 52.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
