High-performance modulized combined switch for automobile

Abstract

Light switches, dimmer switch and steering switch are integrated in light composite module, and each functional switch in the light composite module is controlled by lighting handle. Wiper switch, washer switch are integrated in rain strip unit combination module, and each functional switch in rain strip unit combination module is controlled by rain strip handle. Snap in type connection is provided between light composite module and sectional shelf-unit as well as between rain strip unit combination module and sectional shelf-unit. Socket joint for electrode is setup for each combination module to connect to control circuit in motor vehicle. The invention modularizes each functional module, and adds intermittent rain strip function, making structure of switch simple and reliability.

Description

Technical field: [0001] The invention relates to an automobile combination switch. Background technique: [0002] At present, the combination switches used in automobiles all contain light switches, dimmer switches, steering switches, wiper switches, washer switches and horn switches. Although these switches are combined in form, their combination is only formal. Combination, because each functional switch is controlled by different parts groups, and there is basically no connection between the parts of each group, except that the dimmer switch and the steering switch share a handle to operate, and the other function switches are controlled by different controls. There are more than one hundred parts of this kind of car combination switch, and most of the parts are die-casting parts, metal cutting parts and fasteners. This kind of car combination switch not only has a large number of parts, but also has high assembly requirements and large volume. The function is single, th...

AI Technical Summary

Problems solved by technology

[0007] ①All functional switches are controlled by elastic contacts. Since the mechanical properties of elastic contacts are affected by many factors such as material, processing, heat treatment and assembly, elastic contacts are easily burned during work, and the reliability of the switch not guaranteed

[0008] ② Each function switch is connected to the automobile control circuit through several wire bundles. One end of each wire is welded to the elastic contact piece of each function switch and then led out, and the other end is crimped with the insertion piece and inserted into the insertion piece sheath. During the welding process, the ten wires often have missing welding, virtual welding, desoldering or wrong welding, and the crimping is not firm during the crimping process with the insert piece, which affects the reliability of the combination switch.

[0009] ③In this combination switch, since the intermittent wipe function is not set in the wiper switch, the wiper is not suitable for the weather and climate requirements of our country, and the service life of the wiper is not long

[0010] ④The elastic contacts on each function switch are connected to the pre-set circuit board through wires, and then several wires are drawn from the circuit board to connect with the car control circuit. All solder joints are exposed on the circuit board. In wet weather, water droplets will condense on the circuit board of the contact subassembly, which will easily lead to circuit breakdown, which will directly affect the service life of the car combination switch

[0011] ⑤ The shape and structure of the integral combination switch are extremely complex, there are many types of parts, the assembly process requirements are high, and the maintenance is extremely inconvenient. When a function switch on the car combination switch fails, the entire combination switch needs to be disassembled for maintenance. its a lot of work

[0012] It can be seen that this car combination switch can no longer adapt to the control requirements of modern cars, and there is an urgent need for a high-performance modular car combination switch to replace
