Technical Field

[0001] This patent relates to the field of steering wheel switch wiring technology, specifically a steering wheel switch wiring structure. Background Technology

[0002] A multi-function steering wheel is a steering wheel with function buttons on the sides or bottom, making it easier for the driver to operate. The driver can directly control many electronic devices in the car from the steering wheel without having to search for various buttons on the center console, allowing them to focus more on the road ahead and greatly improving driving safety. This function switch is connected to the car's wiring via wiring.

[0003] However, due to the large number of switches, their wiring needs to be bundled together to form a harness, and then electrically connected to the automotive wiring via a standard plug.

[0004] However, the existing steering wheel switch wiring structure only uses a spiral tube to gather multiple wires, which can only serve to centrally fix the wires. However, the wires are prone to tangling inside, which can cause heat accumulation and damage in the overlapping parts of the wires, affecting the normal use of the switch. Utility Model Content

Detailed Implementation

[0021] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0022] Please see Figure 1-3This patent provides a technical solution: a steering wheel switch wiring structure, including a steering wheel button switch 1 and a switch wiring 2. The steering wheel button switch 1 is inserted into a slot in an external steering wheel, and the switch wiring 2 is inserted into the side wall of the steering wheel button switch 1. The steering wheel button switch 1 is electrically connected to the external vehicle wiring through the switch wiring 2.

[0023] The switch wiring 2 includes a spiral sleeve 21, a limiting block 22, a positioning hole 23, and a wiring 24. The spiral sleeve 21 is inserted into and installed on the side wall of the steering wheel button switch 1. The limiting block 22 is installed on the inner side wall of the spiral sleeve 21. The side wall of the limiting block 22 has a positioning hole 23. The wiring 24 is inserted into and installed in the positioning hole 23. The wiring 24 is electrically connected to the steering wheel button switch 1.

[0024] The spiral sleeve 21 can concentrate and wrap the wiring 24, protecting it from damage caused by friction between the wiring 24 and the external structure. At the same time, the spiral sleeve 21 is also equipped with a limiting block 22. The wiring 24 is inserted into the positioning hole 23 on the limiting block 22, so that the limiting block 22 can support the wiring 24 and separate the wiring 24. This prevents the wiring 24 from getting tangled in the spiral sleeve 21, and prevents the wiring 24 from burning due to heat accumulation, which would affect the normal use of the steering wheel button switch 1.

[0025] Specifically, the side wall of the limiting block 22 is provided with a through hole 3, and a support rod 4 is inserted and installed in the through hole 3. The support rod 4 can support the spiral sleeve 21.

[0026] By setting the strut 4, the spiral sleeve 21 can be supported after it is fitted over the limiting block 22.

[0027] Specifically, the side wall of the limiting block 22 is provided with a sliding groove 5, which is connected to the positioning hole 23. A positioning block 6 is slidably installed in the sliding groove 5, and the positioning block 6 can fit against the side wall of the wiring 24.

[0028] By setting the positioning block 6, after the spiral sleeve 21 is sleeved on the outside of the limiting block 22, it can push the positioning block 6 downward, thereby positioning the wiring 24 through the positioning block 6 and preventing the wiring 24 from sliding.

[0029] Specifically, a standard plug 7 is installed at the end of the switch wiring 2, which can be electrically connected to the interface in the external automotive wiring.

[0030] The reference plug 7 proposed in this article is existing technology. The reference design refers to the use of a unified design standard, including layout and power supply scheme, to ensure stability and compatibility.

[0031] Specifically, a spring 8 is installed inside the sliding groove 5. The spring 8 is sleeved on the outside of the positioning block 6. A convex ring 9 is installed on the outer wall of the positioning block 6. One end of the spring 8 is in contact with the inner wall of the sliding groove 5, and the other end of the spring 8 is in contact with the lower wall of the convex ring 9.

[0032] The spring 8 provides support for the positioning block 6, preventing it from obstructing the wire 24 when it is inserted.

[0033] Specifically, a rubber pad 10 is fitted to the lower wall of the positioning block 6. The rubber pad 10 can fit with the wiring 24. An anti-slip groove 11 is provided on the lower wall of the rubber pad 10.

[0034] The rubber pad 10 prevents the positioning block 6 from damaging the wiring 24, while the anti-slip groove 10 increases the friction between the two, making the positioning of the wiring 24 more effective.

[0035] Working principle: First, insert the wiring 24 into the positioning hole 23 on the limit block 22, and then put its spiral sleeve 21 on the outside of the limit block 22 to wrap the limit block 22 and the wiring 24 to shield and protect them. Then, by plugging the public plug 7 at the end of the switch wiring 2 into the interface in the external car wiring, the steering wheel button switch 1 is connected to the external car wiring through the switch wiring 2, and the electronic equipment in the car can be controlled through the steering wheel button switch 1.
