Description

Technical Field

[0001] This utility model belongs to the technical field of vehicle parts and relates to a vehicle combination switch assembly. Background Technology

[0002] Electric vehicles, motorcycles, and other similar vehicles typically have combination switches installed on their handlebars to control functions such as lights, steering, and horn. Existing combination switch assemblies usually consist of a housing made up of two interlocking half-shells, which are directly fastened to the handlebars using fasteners.

[0003] To prevent the combination switch assembly from rotating or shifting axially on the handlebars, a protrusion, or limit pin structure, is typically integrally molded on the inner wall of one of the half-shells (both the half-shell and the protrusion are made of plastic). This protrusion mates with a pre-set socket on the handlebars. However, due to the limited strength and toughness of plastic, this integrally molded plastic protrusion is prone to breakage under strong impacts or vibrations, causing the critical limiting function to fail. Utility Model Content

[0004] This utility model addresses the shortcomings of existing technologies by providing a vehicle combination switch assembly with higher structural strength and longer service life.

[0005] To solve the above-mentioned technical problems, the objective of this utility model is achieved through the following technical solution: A vehicle combination switch assembly includes a combination switch housing formed by fastening together a first half-shell and a second half-shell split axially. The first half-shell and the second half-shell are fixedly connected by a first fastener. The assembly also includes a separate metal component embedded in the inner wall of the first half-shell. The metal component includes an arc-shaped body portion and mounting ears extending radially from both ends of the arc-shaped body portion. A radially outwardly protruding limiting protrusion is integrally formed on the arc-shaped body portion, and the limiting protrusion is used to cooperate with a pre-set limiting insertion hole on the handlebar. A first through hole is provided on the mounting ears for the first fastener to pass through.

[0006] In the above-mentioned vehicle combination switch assembly, a first threaded post is provided in the first half-shell, and a second through hole is provided in the second half-shell. The first fastener passes through the second through hole of the second half-shell and the first through hole of the mounting ear in sequence, and is then screwed and fixed to the first threaded post of the first half-shell.

[0007] In the above-mentioned vehicle combination switch assembly, a second threaded post is provided inside the first half-shell, and a third through hole is provided on the mounting ear. The second fastener passes through the third through hole and is screwed and fixed to the second threaded post to form a pre-installation structure for the metal part.

[0008] In the above-mentioned automotive combination switch assembly, preferably, the first fastener and the second fastener are fastening screws; more preferably, the size of the first fastener is larger than that of the second fastener.

[0009] In the above-mentioned vehicle combination switch assembly, preferably, the arc-shaped body portion has the same curvature as the inner wall of the first half-shell and the outer wall of the handlebar.

[0010] In the aforementioned automotive combination switch assembly, the first half-shell is provided with a mounting groove adapted to the outer contour of the metal part. The mounting groove, together with the first threaded post and the second threaded post, forms a mounting limiting structure for the metal part. Specifically, the mounting groove provides a limiting structure for the outer contour of the metal part, and the end faces of the first threaded post and the second threaded post abut against the side of the metal part to provide a radial limiting structure.

[0011] In the aforementioned automotive combination switch assembly, the metal part is formed by stamping and bending a metal sheet, and the limiting protrusion is formed by cutting and bending a portion of the arc-shaped body.

[0012] In the aforementioned automotive combination switch assembly, the limiting protrusion is formed by bending outwards from a first cut portion and a second cut portion cut from the edge, and the first cut portion and the second cut portion are symmetrically arranged.

[0013] In the aforementioned automotive combination switch assembly, the end of the first cutting portion is bent toward the direction of the second cutting portion, and the end of the second cutting portion is bent toward the direction of the first cutting portion, forming a columnar structure after they come into contact.

[0014] Compared with the prior art, this utility model has the following advantages: This invention provides a vehicle combination switch assembly that uses an independent metal component with a limiting protrusion to replace the integrally formed limiting pin in the original structure. This significantly increases the strength of the limiting structure of the combination switch assembly, fundamentally preventing vehicle malfunctions or safety accidents caused by limiting pin breakage. Simultaneously, the metal component of this invention also improves the overall structural strength of the combination switch assembly, further extending its service life.

Detailed Implementation

[0016] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1-5 : A vehicle combination switch assembly includes a combination switch housing formed by fastening together a first half-shell 1 and a second half-shell 2 split axially. The first half-shell 1 and the second half-shell 2 are fixedly connected by a first fastener. The assembly also includes an independent metal part 3, which is embedded in the inner wall of the first half-shell 1. The metal part 3 includes an arc-shaped body portion 31 and mounting ears 32 extending radially from both ends of the arc-shaped body portion 31. A radially outwardly protruding limiting protrusion 33 is integrally formed on the arc-shaped body portion 31. The limiting protrusion 33 is used to cooperate with a preset limiting insertion hole 41 on the handlebar 4. A first through hole 34 is provided on the mounting ears 32 for the first fastener to pass through.

[0017] The specific assembly structure of this embodiment is as follows: a first threaded post 11 is provided in the first half-shell 1, and a second through hole 21 is provided in the second half-shell 2. The first fastener passes through the second through hole 21 of the second half-shell 2 and the first through hole 34 of the mounting ear 32 in sequence, and is then screwed and fixed to the first threaded post 11 of the first half-shell 1.

[0018] Furthermore, a second threaded post 13 is provided inside the first half-shell 1, and a third through hole 35 is provided on the mounting ear 32. The second fastener passes through the third through hole 35 and is screwed and fixed to the second threaded post 13 to form a pre-installation structure of the metal part 3.

[0019] Furthermore, the first half-shell 1 is provided with a mounting groove 12 that matches the outer contour of the metal part 3. The mounting groove 12, together with the first threaded post 11 and the second threaded post 13, forms a mounting limiting structure for the metal part 3. Specifically, the mounting groove 12 provides a limiting structure for the outer contour of the metal part 3, and the end faces of the first threaded post 11 and the second threaded post 13 abut against the side of the metal part 3 to provide a radial limiting structure.

[0020] The specific assembly process in this embodiment is as follows: 1. Pre-installation, refer to the attached document. Figure 3 To be continued Figure 5The assembly process begins with the first half-shell 1. The independent metal part 3 is placed within the mounting slot 12 of the first half-shell 1, with its third through hole 35 automatically aligned with the pre-made second threaded post 13 within the first half-shell 1. A second fastener (e.g., a second screw) is passed through the third through hole 35 on the mounting lug 32 of the metal part 3 and screwed into the second threaded post 13 of the first half-shell 1. Tightening this screw to the appropriate torque securely pre-fixes the metal part 3 to the first half-shell 1, forming a pre-installation structure. When no pre-installation structure is used, the pre-installation can be skipped, and subsequent installation steps can be performed directly.

[0021] 2. Final assembly, refer to the attached document. Figure 1 and attached Figure 2 After pre-installation, the combination switch assembly is assembled. The limiting protrusion 33 is inserted into the preset limiting hole 41 on the handlebar 4, placing the first half-shell 1 in a preset position on the handlebar 4. Then, the second half-shell 2 is fastened to the first half-shell 1, forming a combination switch assembly that fits onto the handlebar 4. A first fastener (e.g., a first bolt) is then passed sequentially through the second through hole 21 of the second half-shell 2 and the first through hole 34 of the metal part 3, finally screwed into the first threaded post 11 of the first half-shell 1 to complete the installation.

[0022] When the combination switch assembly is subjected to torsional force, the force is transmitted through the housing to the metal part 3, and is ultimately borne by the high-strength metal limiting protrusion 33 and the limiting socket 41 of the handlebar 4, thereby fundamentally preventing breakage.

[0023] Comparison Appendix Figure 3 In this embodiment, the specific structure of the metal part 3 is that the metal part 3 is formed by stamping and bending a metal sheet, and the limiting protrusion 33 is formed by cutting and bending a part of the arc-shaped body part 31.

[0024] Furthermore, the limiting protrusion 33 is formed by bending outwards the first cutting portion 33a and the second cutting portion 33b cut from the edge, and the first cutting portion 33a and the second cutting portion 33b are symmetrically arranged.

[0025] Furthermore, the end of the first cutting portion 33a is bent toward the direction of the second cutting portion 33b, and the end of the second cutting portion 33b is bent toward the direction of the first cutting portion 33a. After the two come into contact, they form a columnar structure.

[0026] During processing, the first through hole 34 and the third through hole 35 are punched out at predetermined positions. Then, the first cutting part 33a and the second cutting part 33b are symmetrically cut out. After that, the middle part is bent into an arc shape to form the arc-shaped body part 31 and the mounting ear part 32. Then, the first cutting part 33a and the second cutting part 33b are bent outward, and the two ends are further bent towards each other until they touch, forming a columnar structure.

[0027] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection of the present utility model.
