Description

Technical Field

[0001] The invention relates to the technical field of steering wheel atmosphere lights, and in particular to an integrated dual-module combination switch structure for a vehicle-mounted steering wheel. Background Art

[0002] Currently, the steering wheel ambient light module structure on the market is an independent module structure, which includes an ambient light strip, a housing and a wiring harness. The independent module structure increases the material cost and the labor cost of separate assembly. In addition, the independent module structure needs to occupy a certain space when arranged on the steering wheel rim, which has certain limitations on the steering wheel structure layout.

[0003] To this end, the ambient light module structure is integrated into the steering wheel switch. By sharing some parts between the steering wheel switch control module and the ambient light module structure, the structural parts of the independent ambient light module structure are reduced to achieve cost reduction and reduce space requirements. Summary of the invention

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: an integrated dual-module combination switch structure for a vehicle steering wheel, characterized in that it includes a switch housing, on which an atmosphere light module and a switch control module are arranged, the switch control module is used to control various electrical appliances in the vehicle, and the atmosphere light module is used to control the atmosphere light.

[0006] The switch housing comprises an upper housing and a lower housing, and the upper housing and the lower housing are connected via a connecting element.

[0007] A PCB assembly is provided between the upper shell and the lower shell. The PCB assembly and the atmosphere light constitute an atmosphere light module, and the atmosphere light is installed on the upper shell. The PCB assembly and the switch constitute a switch control module, and the switch is installed on the upper shell.

[0008] The PCB assembly is also electrically connected to the wiring harness assembly.

[0009] Compared with the prior art, the beneficial effects achieved by the present invention are: eliminating the existing independent atmosphere light module, integrating the PCB and structural parts required for the atmosphere light module inside the steering wheel switch, and sharing the upper shell, PCB assembly, lower shell, wiring harness assembly and other parts with the switch control module of the steering wheel; saving materials, reducing switch costs, and saving space requirements for the steering wheel.

[0012] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0013] See also Figure 1-2 The present invention provides a technical solution: an integrated dual-module combination switch structure for a vehicle steering wheel, including a switch housing 100, on which an atmosphere light module 300 and a switch control module 400 are arranged. The switch control module 400 is used to control various electrical appliances on the vehicle, such as: controlling multimedia, instruments and cruise functions, etc.; the atmosphere light module 300 is used to control the atmosphere light 301.

[0014] The switch housing 100 includes an upper housing 101 and a lower housing 102 , and the upper housing 101 and the lower housing 102 are connected by a connecting element, for example, they can be connected by using an existing snap-fit ​​structure.

[0015] There is a PCB assembly 500 between the upper shell 101 and the lower shell 102. The PCB assembly 500 and the atmosphere light 301 constitute the atmosphere light module 300, and the atmosphere light 301 is installed on the upper shell 101; the PCB assembly 500 and the switch 401 constitute the switch control module 400, and the switch 401 is installed on the upper shell 101.

[0016] The PCB assembly 500 is also electrically connected to the wiring harness assembly 200 .

[0017] In this embodiment, the upper housing 101 , the PCB assembly 500 , the lower housing 102 , and the wiring harness assembly 200 are both part of the switch control module 400 and part of the ambient light module 300 .

[0018] Furthermore, the lighting and extinguishing of the atmosphere lamp 301 adopts the existing technology, and the specific process is as follows: 1. Turn on. When the vehicle speed reaches a certain speed or changes lanes, the ambient light 301 is activated. The vehicle LIN bus sends an ambient light command to the ambient light module 300 of the steering wheel switch. After receiving the LIN bus ambient light command, the ambient light module 300 works. The ambient light 301 driving module in the ambient light module 300 receives the vehicle signal light command to light up the ambient light 301 of the steering wheel switch.

[0019] 2. Turn off. When the vehicle speed is lower than a certain speed and there is no lane change, the vehicle LIN bus sends a command to turn off the ambient light to the ambient light module 300 of the steering wheel switch. After receiving the command to turn off the ambient light from the LIN bus, the ambient light 301 driver in the ambient light module 300 no longer gives commands to the ambient light module 300 of the steering wheel, and the ambient light 301 of the steering wheel switch goes out.

[0020] The novel configuration of the present invention has the following beneficial effects: the switch control module 400 and the ambient light module 300 share the upper shell 101, PCB assembly 500, lower shell 102, wiring harness assembly 200 and other parts; materials are saved and the cost of the entire vehicle is reduced; at the same time, since the structural parts of the independent ambient light module 300 structure are eliminated, the space requirement for the steering wheel is saved, which facilitates the promotion and application of the solution on the entire vehicle.

[0021] It should be noted that, in this article, the terms "include", "belong to" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0022] Finally, it should be noted that the above description 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 replace some of the technical features therein by equivalents.
