Description

Technical Field

[0001] This utility model belongs to the field of vehicle accessories, specifically relating to a handlebar switch mounting structure for motorcycles / electric vehicles. Background Technology

[0002] In the control systems of motorcycles, electric vehicles, and other vehicles, various function switches (such as lights, horns, and turn signals) are typically integrated into the handlebar switch. This handlebar switch is mounted to the vehicle's metal handlebar via a socket in its housing. Currently, a common installation structure employs a combination of a "clamping plate" and a "locating pin-locating hole" mechanism. Specifically, the switch housing consists of two mating half-shells fastened together with screws. A clamping plate is located inside the housing, and a locating pin protrudes from the inner wall of the socket, with a pre-machined locating hole at the corresponding position on the handlebar. The problem with this structure in actual assembly and use is:

[0003] During installation, first loosen the fixing screws fully, disassemble the outer shell into two parts, and then fit them onto the handle tube from both sides, ensuring that the positioning pins are precisely inserted into the corresponding positioning holes. Then tighten the fixing screws, and finally lock the clamping plate to make it fit tightly against the handle tube to complete the locking installation. The installation process involves many steps, which affects the installation efficiency. Moreover, the clamping plate is usually a stamped part, which has a high manufacturing cost. Utility Model Content

[0004] In response to this, the present invention provides a switch mounting structure that, through structural optimization, enables the rapid and stable installation of the switch unit, and has low manufacturing costs.

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

[0006] This utility model provides a switch mounting structure, including a handle tube and a switch unit. The switch unit includes a housing with a sleeve hole, and the switch unit is sleeved with the handle tube through the sleeve hole. The outer surface of the housing is provided with a through hole extending to the wall of the sleeve hole. The through hole is provided with an internal thread, and a set screw is connected to the internal thread of the through hole. The inner end of the set screw is provided with a spike. After the set screw is tightened, the spike on it pierces into the surface of the handle tube.

[0007] Preferably, the outer end of the set screw is provided with a screwing portion.

[0008] Preferably, the screwing part is a straight groove or a polygonal structure.

[0009] Preferably, a protruding post is provided on the inner wall of the outer shell, and the through hole is provided on the protruding post.

[0010] Preferably, the convex post has multiple ribs protruding from its side, and at least one of the ribs is connected to the inner wall of the outer shell and extends outward.

[0011] Preferably, a hollow metal threaded insert is fixed inside the through hole, and the internal thread is formed on the metal threaded insert.

[0012] Preferably, the outer wall of the metal threaded insert is provided with protruding teeth, which are embedded in the outer shell.

[0013] Preferably, the spike is a conical structure.

[0014] Preferably, the spike of the set screw points towards the center of the sleeve hole.

[0015] Preferably, the surface hardness of the spike is higher than the surface hardness of the handle tube surface.

[0016] The advantages of this invention are as follows: The invention optimizes the structure by innovatively employing a locking method where the spikes directly pierce the surface of the handle tube, eliminating the need for a positioning post. The switch unit can be fitted onto the handle tube as a complete unit at the desired installation position. After adjusting the angle, installation is completed by tightening the set screws. The spikes directly pierce the solid material of the handle tube during locking, forming a mechanical interlocking point for axial and axial locking. This eliminates the need for a positioning post to align with the hole, simplifying the installation process. Furthermore, the switch unit is installed securely and reliably, effectively improving installation efficiency. Additionally, the absence of a clamping plate reduces the number of components and lowers manufacturing costs. Attached Figure Description

[0024] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0025] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0026] The structure of the switch mounting structure in this embodiment of the utility model is as follows: Figures 1 to 4 As shown, the device includes a handle tube 1 and a switch unit 2. The switch unit 2 includes a housing 21 with a sleeve hole 22, which is sleeved onto the handle tube 1. The outer surface of the housing 21 has a through hole 23 extending to the wall of the sleeve hole 22. The through hole 23 has an internal thread, and a set screw 3 is connected to the internal thread of the through hole 23. The inner end of the set screw 3 has a spike 31. After the set screw 3 is tightened, the spike 31 pierces the surface of the handle tube 1. During installation, the switch unit 2 is sleeved onto the handle tube 1 through the sleeve hole 22 and adjusted to a suitable angle, and then the set screw is tightened. Nail 3 is sufficient; This utility model innovatively adopts a locking method in which "the spike 31 directly pierces the surface of the handle tube 1", eliminating the positioning post. The switch unit can be fitted onto the installation position on the handle tube as a complete whole, and after adjusting the appropriate angle, the installation can be completed by tightening the set screw. When locking, the spike 31 directly pierces into the solid material of the handle tube to form a mechanical interlocking point to achieve axial and axial locking. There is no need for the positioning post to align with the hole, simplifying the installation steps. Moreover, the switch unit is installed firmly and reliably, effectively improving the installation efficiency. In addition, there is no need to set a clamping plate, reducing the number of parts and lowering the manufacturing cost.

[0027] Preferably, the spike 31 of the set screw 3 is positioned to point towards the center of the sleeve hole 22, so that when the set screw 3 is locked with the handle tube 1, the set screw 3 can penetrate the handle tube 1 radially to ensure a stable installation.

[0028] Combination Figure 2 and Figure 3As shown, the set screw 3 has a screw-tightening part 32 at its outer end, which allows the user to easily tighten the set screw 3 from the outside using tools during installation. Specifically, the screw-tightening part 32 can be a slotted groove or a polygonal groove (such as a quadrilateral, pentagon or hexagon). When tightening, the end of the screwdriver is inserted into the screw-tightening part 32 to tighten it, which is convenient to operate.

[0029] See Figure 2 and Figure 4 The inner wall of the outer casing 21 is provided with a protruding post 24, and the through hole 23 is provided on the protruding post 24. The setting of the protruding post 24 enhances the wall thickness of the corresponding part of the outer casing 21, thereby increasing the axial dimension of the through hole 23, which in turn helps to extend the effective engagement length of the internal thread, so that the set screw 3 can engage with it at a greater screw depth, thereby enhancing the stability of the locking installation of the switch unit 2.

[0030] See Figure 4 As shown, the protruding post 24 has multiple ribs 241 protruding from its side. The ribs 241 can strengthen the protruding post 24 and effectively suppress the deformation and fracture risk at the root of the protruding post 24. Furthermore, at least one of the ribs 241 is connected to the inner wall of the outer shell 21 and extends outward. In this way, when the set screw 3 applies pressure, the ribs 241 can transfer the stress concentrated on the protruding post 24 outward and guide it to the inner wall of the outer shell 21 with a larger area, thereby avoiding local stress concentration and reducing the possibility of the outer shell 21 cracking due to stress concentration.

[0031] In some embodiments, combined with Figure 2 , Figure 4 and Figure 5 As shown, a hollow metal threaded insert 25 is fixed inside the through hole 23. The internal thread is formed on the metal threaded insert 25. Compared with the thread formed by tapping directly on the plastic shell 21, the metal threaded insert 25 (such as copper or steel) has higher hardness and tear resistance, and can withstand repeated tightening without stripping, thereby ensuring the stability of the switch unit 2 installation.

[0032] See Figure 5 The outer wall of the metal threaded insert 25 is provided with protruding teeth 251, which are embedded in the outer shell 21. This design ensures that the metal threaded insert 25 is firmly fixed in the outer shell 21. When the metal threaded insert 25 is pressed in or injection molded into the plastic outer shell 21, the protruding teeth 251 (such as knurling or barbs) will bite into the surrounding plastic material, thereby effectively preventing the metal threaded insert 25 from loosening and ensuring the stability of the metal threaded insert 25.

[0033] like Figure 2As shown, the spike 31 has a conical structure. The conical structure is a preferred and efficient form of the spike 31. Its inclined surface can generate a huge radial force during the locking process, making the action of "piercing" the handle tube 1 smoother and less strenuous. At the same time, it provides a larger contact area than a simple needle tip, making the formed mechanical interlock more stable and optimizing the anti-rotation ability and vibration resistance.

[0034] As a preferred technical solution in this embodiment, the surface hardness of the spike 31 is higher than the surface hardness of the handle tube 1. This ensures that during the tightening process of the set screw 3, the spike 31 can be fully pressed into and embedded in the relatively soft surface of the handle tube 1, while the screw itself will not be chipped, broken, or plastically deformed, thereby forming a stable and reliable mechanical interlock.

[0035] For those skilled in the art, other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations. However, these obvious variations or modifications derived from the essential spirit of this invention still fall within the protection scope of this invention.
