Description

Technical Field

[0001] This utility model relates to the field of communication switch equipment technology, and in particular to a CAN communication combination switch assembly. Background Technology

[0002] The CAN (Controller Area Network) combination switch is a highly integrated control module based on bus communication technology. It connects to the vehicle's central controller (ECU) via the CAN bus to achieve multifunctional centralized control and status feedback.

[0003] Traditional hard-wired switches primarily connect directly to the controlled equipment or control center via physical wires. Each switch requires an independent wire to transmit control signals, resulting in complex wiring, especially when connecting multiple switches and devices. This leads to a large number of wires, high wiring costs, and difficult line maintenance. Furthermore, traditional combination switches have relatively limited functionality, typically only providing simple on / off or state switching. Adding other functions, such as status feedback, dimming, or color adjustment, requires additional wiring and equipment, making modifications challenging.

[0004] Therefore, those skilled in the art are dedicated to developing a CAN communication combination switch assembly that not only facilitates switch control but also enables timing control, analog signals, and meets diverse needs for different signal outputs. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide a CAN communication combination switch assembly, which not only facilitates switch control, but also enables timing control, analog signals, and meets the diverse needs of different signal outputs.

[0006] The technical solution of this utility model to solve the above-mentioned technical problems is as follows:

[0007] A CAN communication combination switch assembly, including

[0008] A fixing component for connection to the handlebars;

[0009] A PCB board assembly, which is mounted on the fixing assembly and is connected to a power supply assembly;

[0010] A button assembly is mounted on the fixed assembly via a button mounting bracket, and the button assembly is located directly above the PCB board assembly.

[0011] The advantages of adopting the above scheme are: by using CAN bus communication technology, compared with traditional hard wire connection, a large number of physical wires are reduced, the wiring cost and complexity are reduced, and the stability and anti-interference ability of signal transmission are improved. Each switch does not need to transmit signals with independent wires, avoiding the electromagnetic interference and signal attenuation problems that may occur between many wires in the traditional wiring method. This ensures the accurate and timely transmission of control signals, thereby improving the reliability and response speed of the entire vehicle control system, ensuring that various operations during vehicle driving can be executed accurately, and enhancing the safety and comfort of the vehicle.

[0012] Connecting to the vehicle's central control unit (ECU) via the CAN bus enables multi-functional centralized control and status feedback that far surpasses traditional hard-wired switches. Breaking away from the limitations of traditional single-function combination switches, it not only performs basic switching control but also supports timing control, analog signals, and other functions, meeting diverse needs for different signal outputs. Functions such as dimming and color adjustment are simplified without requiring extensive additional complex wiring and equipment. This provides strong support for intelligent vehicle control and functional expansion, better adapting to the modern vehicle's demands for various intelligent and personalized functions, and enhancing the vehicle's technological sophistication and user experience.

[0013] Based on the above technical solution, the present invention can be further improved as follows.

[0014] Furthermore, the PCB board assembly includes a PCB board having a CAN controller, a CAN transceiver, and a contact button, and a silicone pad is provided between the contact button and the button assembly.

[0015] The advantages of adopting the above-mentioned further solution are: setting up a CAN controller and CAN transceiver on the PCB board can efficiently realize CAN bus communication with the vehicle's central controller (ECU), ensure the fast and accurate transmission of switch control signals, meet the control requirements of various complex operating conditions of the vehicle, and make the vehicle's control response more sensitive and precise.

[0016] Furthermore, the button assembly includes a button cap, a button rocker plate is mounted on the underside of the button cap, the button rocker plate has a rotating column in the middle, and the rotating column is rotatably connected to the button mounting bracket.

[0017] The beneficial effects of adopting the above-mentioned further solution are as follows: the button assembly consists of a button cap, a button rocker plate, and a rotating column. The rotating column in the middle of the button rocker plate is rotatably connected to the button mounting bracket, which makes the button more flexible and smooth during the pressing and resetting process, providing a good operating feel, while ensuring the stability and reliability of button operation, and avoiding control errors caused by button jamming or unsmooth operation.

[0018] Furthermore, the button mounting bracket includes a button rocker bracket, which is mounted on the fixing assembly. The button rocker bracket has a rotating hole, and the rotating column passes through the rotating hole.

[0019] The beneficial effects of adopting the above-mentioned further solution are: the button mounting bracket includes a button rocker bracket mounted on the fixed component, and the bracket has a rotating hole that cooperates with the rotating column, which makes the connection between the button assembly and the fixed component more stable, and can withstand greater operating force without loosening. This effectively improves the stability and durability of the combination switch assembly during long-term use and reduces the risk of failure caused by loose parts.

[0020] Furthermore, the fixing assembly includes a front fixing bracket and a rear fixing bracket. The PCB board assembly is mounted on the front fixing bracket. The front fixing bracket has a first engagement cavity, and the rear fixing bracket has a second engagement cavity. The first engagement cavity and the second engagement cavity are arranged opposite to each other and form a fixing cavity for engaging the handlebars. The front fixing bracket and the rear fixing bracket are connected by screws.

[0021] The advantages of adopting the above-mentioned further solution are: the fixing component consists of a front fixing bracket and a rear fixing bracket, forming a fixing cavity for engaging the handlebars, which can be adapted to handlebars of different diameters. The front and rear brackets are connected by screws, making installation and disassembly convenient and quick, without the need for special tools and complicated operations, thus improving installation efficiency.

[0022] Furthermore, a knob and a knob bracket are also installed on the fixing component, with the knob located directly above the PCB board assembly.

[0023] The beneficial effects of adopting the above-mentioned further solution are: the knob and knob bracket are installed on the fixed component, and the knob is located directly above the PCB board component. By rotating the knob or applying force to the contact, functions such as dimming, color adjustment, brightness, and flashing frequency can be achieved, which increases the functional diversity of the combination switch assembly. Moreover, the knob operation is intuitive and convenient, allowing users to flexibly adjust the working status of vehicle-related equipment according to actual needs, thereby improving the user's operational convenience and user experience.

[0024] Furthermore, an annular isolation cavity is provided on the PCB board and located around the contact button, the annular isolation cavity being made of mica insulating adhesive.

[0025] The beneficial effects of adopting the above-mentioned further solution are: an annular isolation cavity made of mica insulating adhesive is set around the contact button on the PCB board. Mica insulating adhesive has excellent insulation and high temperature resistance, which can effectively isolate the electrical connection between the contact button and other circuit components, prevent arcing and current leakage, improve the stability and safety of the circuit, and ensure the reliable operation of the combination switch assembly under complex working conditions.

[0026] Furthermore, an arc-extinguishing grid is also provided on the PCB board and located at the contact button.

[0027] The beneficial effects of adopting the above-mentioned further solution are: an arc-extinguishing grid is set at the contact button on the PCB board. The arc-extinguishing grid can quickly guide the electric arc generated when the contact is broken to the grid between the grids. The cooling and dividing effect of the grids extinguishes the electric arc, effectively reducing the burning and damage of the contact by the electric arc, extending the service life of the contact, and improving the breaking capacity of the contact and the safety of the combination switch assembly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0037] like Figure 1 , Figure 2 and Figure 3 As shown, a CAN communication combination switch assembly includes...

[0038] Fixing component 1, which is used to connect to handlebar 2;

[0039] PCB board assembly 3 is mounted on fixed assembly 1 and is connected to power supply assembly;

[0040] Button assembly 4 is mounted on fixed assembly 1 via button mounting bracket 5, and button assembly 4 is located directly above PCB board assembly 3.

[0041] In this invention, by utilizing CAN bus communication technology, compared to traditional hard-wired connections, the use of a large number of physical wires is reduced, lowering wiring costs and complexity. At the same time, it improves the stability and anti-interference capability of signal transmission. Each switch does not require an independent wire to transmit signals, avoiding electromagnetic interference and signal attenuation problems that may occur between numerous wires in traditional wiring methods. This ensures accurate and timely transmission of control signals, thereby improving the reliability and response speed of the entire vehicle control system, ensuring that various operations during vehicle operation can be executed precisely, and enhancing vehicle safety and comfort.

[0042] like Figure 1 , Figure 2 and Figure 3 As shown, in some embodiments, the PCB board assembly 3 includes a PCB board 6, which has a CAN controller, a CAN transceiver, and contact buttons. The CAN controller is responsible for organizing and processing data according to the CAN bus protocol, converting control signals from the button assembly 4 into data frames conforming to the CAN bus standard, and sending them to the CAN transceiver. The CAN transceiver is responsible for converting the data frames sent by the CAN controller into electrical signals suitable for transmission on the CAN bus and sending them to the CAN bus. It can also receive data frames sent from other devices on the CAN bus and convert them into signals that the CAN controller can process. When the above method is adopted, the combination switch assembly can perform efficient and reliable data communication with other electronic control units of the vehicle (such as the engine control unit, body control unit, etc.), realizing centralized control and status feedback of various functions of the vehicle.

[0043] A silicone pad 7 is also provided between the contact button and the button assembly 4. When the button assembly 4 is pressed, the silicone pad 7 is squeezed, which forms an effective electrical connection between the contact button and the button assembly 4, thereby realizing the conduction of the circuit. At the same time, the silicone pad 7 can also play a certain role in buffering and sealing, preventing external impurities from entering, and facilitating a tight contact between the contact button and the button.

[0044] An annular isolation cavity is provided on PCB board 6 around the contact button. This cavity is made of mica insulating adhesive, which has excellent insulation and high-temperature resistance, effectively isolating electrical connections between different circuit components and preventing arcing and current leakage. An arc-extinguishing grid is also provided on PCB board 6 around the contact button. When the contact button is opened, the grid quickly guides the generated arc to the space between the grids, extinguishing it through cooling and separation. This protects the contact button from arc erosion and extends its service life.

[0045] like Figure 1 , Figure 2 As shown, in some embodiments, the button assembly 4 includes a button cap 8, a button rocker 9 mounted on the lower side of the button cap 8, a rotating post 10 in the middle of the button rocker 9, a button mounting bracket 5 rotatably connected to the rotating post 10, and a spring mounted on the lower middle side of the button rocker 9 and the button mounting bracket 5. When the user presses the button cap 8, the button rocker 9 rotates around the rotating post 10, thereby realizing the button pressing or resetting action, and locking the pressing or resetting action under the action of the spring force.

[0046] The button mounting bracket 5 includes a button rocker bracket 11, which is mounted on the fixing component 1. The button rocker bracket 11 has a rotating hole 12, and the rotating column 10 passes through the rotating hole 12.

[0047] The fixing assembly 1 includes a front fixing bracket 13 and a rear fixing bracket 14. The PCB board assembly 3 is mounted on the front fixing bracket 13. The front fixing bracket 13 has a first engaging cavity, and the rear fixing bracket 14 has a second engaging cavity 15. The first engaging cavity and the second engaging cavity 15 are arranged opposite to each other to form a fixing cavity for engaging the handlebar 2. The front fixing bracket 13 and the rear fixing bracket 14 are connected by screws 16, so that the fixing assembly 1 can be firmly installed on the handlebar 2, providing stable support and fixing for the entire combination switch assembly, while facilitating installation and disassembly. The combination switch assembly, through the engagement of the front fixing bracket 13 and the rear fixing bracket 14 and the connection of the screws 16, can closely fit the shape of the handlebar 2, ensuring that it will not loosen due to vibration or external force during vehicle operation, thus guaranteeing the normal use and stability of the combination switch assembly.

[0048] In one embodiment, a knob 17 and a knob bracket are also mounted on the fixing component 1. The knob 17 is located directly above the PCB board assembly 3. The knob 17 is designed to provide users with more diverse operating methods and is typically used to implement functions that require continuous adjustment, such as dimming, color adjustment, and volume control. When the user rotates the knob 17, the knob's movement is transmitted to the corresponding circuits on the PCB board assembly 3 through a corresponding mechanical structure, electrical connection, or different forces, thereby achieving the adjustment and control of the relevant functions. The knob bracket is used to support and fix the knob 17, ensuring its stability and reliability during operation.

[0049] In other embodiments, an LED indicator is added inside each button cap 8 of the button assembly 4. The LED indicator is connected to a corresponding circuit on the PCB board assembly 3 via wires to display the button's operating status. For example, when a button is pressed, the corresponding LED indicator lights up, indicating that the button is in the working state; when the button is released, the LED indicator turns off, indicating that the button is in the off state. This intuitive status display function allows users to understand the working status of each button during operation, improving the convenience and accuracy of operation. Simultaneously, the LED indicator can be set with different colors and flashing modes as needed to represent different functional states or reminder information, further enhancing the human-machine interaction function of the combination switch assembly.

[0050] A signal processing chip has been added to PCB board 6 of PCB board assembly 3. The signal processing chip is mainly used to further amplify, filter, and perform analog-to-digital conversion on the signals from button assembly 4 and knob 17 to improve signal quality and stability. The signal processed by the signal processing chip is then transmitted to the CAN controller and sent to the vehicle's central controller (ECU) via the CAN bus, thereby ensuring that the vehicle control system can accurately and timely receive the control signals from the combination switch assembly, improving the reliability and response speed of the entire vehicle control system.
