This is usually done by installing a combination switch on the steering wheel. The existing steering wheel combination switch is an adjustment component installed on the steering wheel for controlling the lights. It is easy to install, adjust, and universally applicable.

[0003] According to a combination switch based on a 3D Hall sensor disclosed in authorized patent application number 202323281453.X, existing steering wheel combination switches, during installation and use, rely on support ridges to support the gaps created inside the switch during frequent adjustments. This frequent adjustment also causes friction damage to the support ridges in contact with the swing seat, resulting in gaps and instability. This makes it difficult to maintain a stable and tight grip during adjustments, reducing stability and affecting the support stability of the combination switch when mounted on a car steering wheel. Therefore, this utility model proposes a universal automotive steering wheel combination switch. Utility Model Content

[0004] This utility model addresses the problem that existing steering wheel combination switches, during installation and use, suffer from friction damage due to the support ridges creating gaps inside the switch during frequent adjustments. This results in unstable movement and makes it difficult to maintain a stable and tight grip, thus reducing stability during use. This utility model provides a significantly different solution from existing technologies. To overcome the aforementioned shortcomings of existing technologies, this utility model provides an automotive air conditioning black box controller, aiming to solve the problems mentioned in the background.

[0005] To achieve the above objectives, this utility model provides a universal automotive steering wheel combination switch, comprising a combination switch body, the combination switch body including a switch handle and a circuit board, a handle connector being provided at the end of the switch handle, a swing seat being mounted on the surface of the handle connector via an auxiliary rotating shaft, and a main rotating shaft being provided on both the upper and lower surfaces of one end of the swing seat, and the combination switch body further comprising:

[0008] Preferably, a D Hall sensor is fixed at the middle position of the upper surface of the circuit board, a magnet is fixed at one end of the lower surface of the handle connector, and the magnet is correspondingly arranged with the D Hall sensor. A sealed protective cover is fitted onto the bottom end of the switch handle on one side of the swing base.

[0009] Preferably, the fixed mounting assembly includes mounting seats that are fixedly mounted on the upper surface of the swing seat and on both sides of the handle connector by screws, and the mounting seats have limit grooves inside.

[0010] Preferably, the elastic support assembly includes a limiting support plate that slides within the limiting groove, and a compression spring is fixed at the connection between the lower surface of the limiting support plate and the bottom of the limiting groove.

[0015] The beneficial effects of this utility model are:

[0016] In use, this utility model, through the design of a stable support mechanism, ensures that when the combination switch body is adjusted after installation, the deformation of the compression spring causes the limiting support plate to always elastically press against the inner surface of the swing seat, causing the ball bearing to rotate stably. Similarly, the swing seat and the inside of the steering wheel housing are stably pressed against each other by the limiting support plate and the ball bearing for adjustment. Therefore, it is easy to always maintain a tight support contact while the ball bearing rolls, which is not prone to friction damage and provides stable tight pressing adjustment, thus improving the support stability of the combination switch body when it is installed on the car steering wheel for adjustment.

[0027] Please see Figures 1 to 5 This utility model provides a technical solution: a universal automotive steering wheel combination switch, including a combination switch body 100, which includes a switch handle 101 and a circuit board 106. A handle connector 104 is provided at the end of the switch handle 101. A swing seat 103 is mounted on the surface of the handle connector 104 via an auxiliary rotating shaft. A main rotating shaft 108 is provided on both the upper and lower surfaces of one end of the swing seat 103. A 3D Hall sensor 105 is fixed at the middle position of the upper surface of the circuit board 106. A magnet 107 is fixed at one end of the lower surface of the handle connector 104, and the magnet 107 is correspondingly positioned with the 3D Hall sensor 105. A sealing protective cover 102 is fitted onto the bottom end of the switch handle 101 on one side of the swing seat 103. The combination switch body 100 also includes:

[0028] The stable support mechanism includes a fixed mounting assembly fixed to the upper surface of the swing seat 103 and both sides of the handle connector 104. The fixed mounting assembly has an elastic support assembly inside and a rolling assembly on its surface. When the handle connector 104 and the swing seat 103 are adjusted by turning, the stable support mechanism can stably support the rotation of the swing seat 103 and the handle connector 104, making it less prone to friction and always pressing firmly during adjustment.

[0029] In order to facilitate installation and tightening adjustment by means of a fixed mounting component, in this embodiment, preferably, the fixed mounting component includes a mounting base 1031 fixedly mounted on the upper surface of the swing seat 103 and on both sides of the handle connector 104 by screws, and the mounting base 1031 has a limiting groove 1036 inside, so that the limiting support plate 1032 can be elastically installed inside the mounting base 1031, which facilitates installation and elastic tightening.

[0030] To facilitate stable and tight adjustment between the handle connector 104 and the swing seat 103 using an elastic support assembly, and to prevent gap wobbling, in this embodiment, preferably, the elastic support assembly includes a limiting support plate 1032 that slides within the limiting groove 1036. A compression spring 1035 is fixed at the connection between the lower surface of the limiting support plate 1032 and the bottom of the limiting groove 1036. The limiting support plate 1032 and the interior of the limiting groove 1036 are elastically connected by the compression spring 1035. When the swing seat 103 and the handle connector 104 are adjusted by turning, the deformation of the compression spring 1035 causes the limiting support plate 1032 and the ball bearing 1033 to elastically and stably support and support the swing seat 103, thus facilitating stable adjustment.

[0031] In order to facilitate the adjustment of the limiting support plate 1032 by means of the rolling assembly and reduce friction, in this embodiment, preferably, the rolling assembly includes a rolling groove 1034 formed at the top of the limiting support plate 1032, and a ball bearing 1033 rolling inside the rolling groove 1034. When the limiting support plate 1032 is pressed tightly, the ball bearing 1033 contacts the inner surface and rolls with it, so that friction is not easily generated when adjusting.

[0032] The heat dissipation support mechanism includes support mounting components disposed on both sides of the lower surface of the circuit board 106. The sides of the two sets of support mounting components are provided with heat dissipation components on the lower surface of the circuit board 106. When the circuit board 106 generates heat during the installation and use of the combination switch body 100, the heat dissipation support mechanism can effectively dissipate heat from the bottom of the circuit board 106, resulting in a more significant heat dissipation effect and improving the convenience of supporting and dissipating heat from the bottom of the circuit board 106 when the combination switch body 100 is installed on a car steering wheel.

[0033] To facilitate the support and fixation of the circuit board 106 using the support mounting assembly, and to make installation and use more convenient, in this embodiment, preferably, the support mounting assembly includes support mounting plates 1061 that are fixedly mounted on both sides of the lower surface of the circuit board 106 by screws. The connection point of the two support mounting plates 1061 is located on the lower surface of the circuit board 106 and a heat dissipation mesh plate 1062 is fixed thereon. During the installation of the circuit board 106, the support mounting plates 1061 can support the circuit board 106 for open-cut installation, and after installation, the heat generated by the circuit board 106 can be effectively dissipated to the bottom through the heat dissipation mesh plate 1062.

[0034] In order to facilitate heat dissipation by supporting the bottom of the circuit board 106 through the heat dissipation assembly, in this embodiment, preferably, the heat dissipation assembly includes partition plates 1063 that are fixed at equal intervals on the lower surface of the heat dissipation mesh plate 1062. A heat dissipation channel 1064 is formed at the connection of the two partition plates 1063. When the circuit board 106 is installed and used and generates heat, the bottom of the circuit board 106 is stably supported by the partition plates 1063 and the heat dissipation channel 1064, so that the bottom is hollowed out and heat is effectively dissipated.

[0035] The working principle and usage process of this utility model are as follows: Before use, this universal automotive steering wheel combination switch is first fixedly installed. The circuit board 106 is fixedly installed at the position of the automotive steering wheel housing using screws. Then, the handle connector 104 is installed on the automotive steering wheel via the main shaft 108. After installation, the sealing protective cover 102 seals and protects the connection between the switch handle 101 and the steering wheel. In use, directly moving the switch handle 101 causes the sealing protective cover 102 to move up and down inside the swing base 103 to adjust the corresponding lights. The switch handle 101, through the sealing protective cover 102, drives the swing base 103 to move back and forth via the handle connector 104 to adjust the corresponding lights. When the switch handle 101 is moved upwards, the position of the magnet 107 at the handle connector 104 relative to the 3D Hall sensor 105 also changes. Due to the change in the position of the magnet, the 3D Hall sensor 105 senses the change in magnetic field strength and outputs it to the corresponding module in the vehicle through a hard wire. The output form includes PWM and SENT signals. After receiving the signal output by the combination switch, the relevant module in the vehicle processes it to illuminate the corresponding light and sends the signal to the instrument panel via CAN or LIN. The instrument panel then processes the signal as an indicator light, making it easy for the driver to identify this function and facilitating universal installation and use (this technology is existing technology and is known to be disclosed in authorized patents, so it will not be described in detail here).

[0036] Then, when the circuit board 106 is fixedly installed on the main body 100 of the combination switch before use, the bottom end of the circuit board 106 is supported and placed by the support mounting plate 1061, and the circuit board 106 is fixedly installed and used after the support mounting plate 1061 is placed. At this time, the bottom end of the circuit board 106 is in a hollow support state, so that when the circuit board 106 generates heat during long-term use, the heat dissipation mesh plate 1062 dissipates the heat at the bottom end of the circuit board 106, and the heat is again separated to the end by the heat dissipation channel 1064 and discharged to the outside. This facilitates the support and installation of the bottom end of the circuit board 106 and the rapid heat dissipation treatment. Compared with the bottom end of the circuit board 106 contacting the inner surface of the housing, the heat dissipation effect is more obvious, which improves the convenience of the support and installation of the bottom end of the circuit board 106 for heat dissipation treatment when the main body 100 of the combination switch is installed on the steering wheel of a car.

[0037] Finally, when the combination switch body 100 is installed and adjusted for use, and when it is rotated up and down on the inner surface of the handle connector 104 and the swing seat 103, and when the swing seat 103 is adjusted laterally with the inside of the housing, the compression spring 1035 deforms and drives the limit support plate 1032 to elastically connect. When the limit support plate 1032 is elastically connected, it drives the ball bearing 1033 to contact the inner surface of the housing or the inner surface of the swing seat 103. Therefore, when adjusting between the handle connector 104 and the swing seat 103, the limit support plate 1032 is always elastically pressed and drives the ball bearing 1033 to contact the inner surface of the swing seat 103 for stable rotation and adjustment. Similarly, the swing seat 103 and the inside of the steering wheel housing are stably pressed and adjusted by the limit support plate 1032 and the ball bearing 1033. Therefore, it is easy to always press and support the contact while the ball bearing 1033 rolls, which is not easy to cause friction damage. The stable pressing and adjusting improves the support stability of the combination switch body 100 when it is installed on the car steering wheel for adjustment.

[0038] The above-disclosed embodiments are merely preferred embodiments of the present utility model and should not be construed as limiting the scope of the present utility model. Those skilled in the art can understand that implementing all or part of the above-described embodiments and making equivalent changes in accordance with the claims of the present utility model are still within the scope of the utility model.
