[0003] The existing steering wheel switch assembly and the steering wheel assembly in actual use, due to the application of intelligence, the steering wheel switch assembly has intelligent interaction. Although some smart steering wheels support voice interaction functions, in actual use, since the microphone is not set on the steering wheel assembly, it needs to be connected to the vehicle system by a line. When the driver in the driving seat speaks, there may be a problem of low voice recognition accuracy. In addition, its interaction method is single and can only rely on voice feedback, and its interaction convenience is not good.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a steering wheel switch assembly and a steering wheel assembly are provided. Summary of the invention

The overall structure of the steering wheel switch assembly is designed with multiple interactions, and the noise reduction microphone is provided at the lower end of the switch assembly controller. After the steering wheel assembly is installed on the car, the noise reduction microphone is provided at the driving position to facilitate the collection of the driver's voice commands, and the upper end of the switch assembly controller is provided with an image collector, which includes infrared and portrait lenses and can detect the driver's face. When the driver performs voice control, the image collector monitors the driver's mouth shape to determine his voice, and compares it with the collected voice data of the noise reduction microphone, comprehensively corrects the driver's voice command at the terminal, and transmits it to the vehicle system for execution, thereby solving the problem of low voice recognition accuracy.

[0007] Furthermore, a horn push switch is fixedly installed at the center position of the front end of the switch assembly controller in a snap-on manner, four first control switches are fixedly installed on the circumference of the switch assembly controller in an X-shape and at equal angles, and a second control switch is fixedly installed at the middle position of each of the two ends of the switch assembly controller. It adopts a multiple separate independent control switch structure design, and its multiple control switches are evenly distributed in the center of the steering wheel, which is convenient for the driver to observe and press, and damage to the single control switch structure does not affect the use of the remaining control switches.

The ECU is the core control component of the vehicle's electronic system. It is responsible for receiving and processing signals from various sensors and controlling the operation of various systems of the vehicle based on these signals.

[0031] Example:

[0032] As attached Figure 1 To Attachment Figure 8 As shown:

[0033] The present invention provides a steering wheel switch assembly, including a switch assembly 2, wherein the switch assembly 2 includes a switch assembly controller 212; an image collector 214 is arranged in the middle of the upper end of the switch assembly controller 212, and a noise reduction microphone 216 is arranged in the middle of the lower end of the switch assembly controller 212. The overall structure of the steering wheel switch assembly with multiple interactions is designed, and the noise reduction microphone 216 is arranged at the lower end of the switch assembly controller 212. After the steering wheel assembly is installed on the car, the noise reduction microphone 216 is arranged at the driving position to facilitate the collection of the driver's voice commands, and the image collector 214 is arranged at the upper end of the switch assembly controller 212, which includes infrared and portrait lenses and can detect the driver's face. When the driver performs voice control, the image collector 214 monitors the driver's mouth shape to determine the driver's voice, and compares the collected voice data with the noise reduction microphone 216, and comprehensively corrects the driver's voice command of the terminal, and transmits it to the vehicle system for execution, thereby solving the problem of low voice recognition accuracy.

[0034] Among them, a horn push switch 217 is fixedly installed in the front center position of the switch assembly controller 212 in a snap-on manner, four first control switches 213 are fixedly installed on the side of the switch assembly controller 212 in an X-shaped and equiangular shape, and a second control switch 215 is fixedly installed in the middle position of each of the two ends of the switch assembly controller 212. It adopts a multiple separate independent control switch structure design, and its multiple control switches are evenly distributed in the center of the steering wheel, which is convenient for the driver to observe and press, and damage to its single control switch structure does not affect the use of other control switches.

[0035] Among them, a mounting plate 211 is fixedly installed at the rear end of the switch assembly controller 212, a gas generator 28 is fixedly installed at the rear end of the mounting plate 211, inflation nozzles 29 are arranged on both sides of the front end of the gas generator 28, and airbags 210 are installed at the front ends of the two inflation nozzles 29. The mounting plate 211 and the switch assembly controller 212 are provided with through grooves for the airbags 210 to be inflated and ejected at the center position, a pressure sensor 27 is fixedly installed at the center position of the rear end of the gas generator 28, and a steering gear 21 is arranged at the rear end of the gas generator 28. When the vehicle collides, the airbag 210 is quickly inflated and ejected to provide buffer protection for the driver. The material of 10 should have high strength and good flexibility, be able to withstand huge impact force in an instant and protect the driver's head and chest. When a collision occurs, the gas generator 28 quickly generates gas to fill the airbag 210. The performance of the gas generator 28 should be reliable and be able to generate enough gas in a very short time to ensure the normal operation of the airbag 210. The pressure sensor 27 is used to detect the collision signal of the vehicle and trigger the pop-up of the airbag 210. The sensitivity and accuracy of the pressure sensor 27 are crucial. It must be able to accurately judge the intensity and direction of the collision so that the airbag 210 can be activated in time when needed.

[0036] Among them, the rotating end at the front center position of the steering gear 21 is fixedly connected to the front gas generator 28, and the front peripheral fixed end of the steering gear 21 is fixedly connected to the shift controller 24. A shift paddle 25 is arranged on each side of the shift controller 24, and a paddle connecting shaft 26 is fixedly connected to the opposite end of the two shift paddles 25. The bottom end of the paddle connecting shaft 26 is fixedly connected to the paddle shift control switch of the shift controller 24. A shift paddle 25 mechanism is arranged on each side of the shift mechanism. The shift paddle 25 mechanism on one side can be used for upshift control, and the shift paddle 25 mechanism on the other side can be used for downshift control, which is more convenient, that is, the vehicle speed control system is connected via a control line through the shift controller 24.

[0037] Among them, after the vehicle speed control system sensor detects the movement of the paddle, it will send a corresponding signal to the vehicle's electronic control unit ECU. The ECU is the core control component of the vehicle's electronic system. It is responsible for receiving and processing signals from various sensors and controlling the operation of various systems of the vehicle based on these signals. After receiving the signal from the shift paddle 25, the ECU will perform comprehensive analysis and calculation based on the current vehicle driving state, such as vehicle speed, engine speed, throttle opening, vehicle load and other parameters to determine the best shift timing and target gear. Once the ECU determines the shift command, it will control the hydraulic system inside the transmission through the solenoid valve. The hydraulic system changes the flow direction and pressure of the hydraulic oil to push the shift mechanism inside the transmission to achieve gear switching, thereby completing the shift operation. For example, when upshifting, the hydraulic system will push the corresponding gear combination to reduce the transmission ratio of the transmission and achieve a higher vehicle speed; when downshifting, the hydraulic system will switch to a lower gear to increase the engine speed and provide greater torque.

[0038] Among them, the rear end of the steering gear 21 is fixedly connected with a matching connector 22, and the matching connector 22 and one end of the steering gear 21 are both provided with wiring ports 23. The wiring port 23 of the matching connector 22 can be connected to the vehicle computer system through a control line, and the wiring port 23 of the steering gear 21 can be connected to the steering control system of the vehicle through a control line.

[0039] A steering wheel assembly includes a steering wheel body 1, wherein the steering wheel body 1 includes a rim 11. The inner frame of the rim 11 is made of aluminum alloy and provides a solid structural support for the steering wheel, which determines the overall strength and durability of the steering wheel and can withstand various forces applied by the driver during operation. The outer surface of the rim 11 is made of leather, which is easy to clean and durable. Sponge is filled between the inner frame and the outer surface of the rim 11, which is easy to clean, and the plastic outer skin is more durable. A center seat 13 is fixedly connected to the inner wall of the rim 11, which can be used for arranging a steering wheel switch assembly.

[0040] Among them, a first matching groove 14 for the second control switch 215 to be slidably fitted and installed is opened between the front and rear side walls at both ends of the center seat 13, which plays a role in protecting the periphery of the second control switch 215; a second matching groove 15 for the noise reduction microphone 216 to be slidably fitted and installed is opened between the front and rear side walls below the center seat 13, which plays a role in protecting the periphery of the noise reduction microphone 216; a third matching groove 16 for the speaker push switch 217 to be slidably fitted and installed is opened in the middle of the center seat 13, which plays a role in protecting the periphery of the speaker push switch 217.

[0041] Working principle of this embodiment: The steering wheel switch assembly usually includes multiple control switches for lighting control, wiper control, horn control, etc. Its working principle is that the switch assembly 2 is connected to the matching connector 22 via a connecting line, and the wiring port of the matching connector 22 can be connected to the car system through a control line. At this time, the corresponding functions of the vehicle can be controlled by multiple control switches. In addition, the overall structure of the steering wheel switch assembly is designed with multiple interactive steering wheels. A noise reduction microphone 216 is arranged at the lower end of the switch assembly controller 212. After the steering wheel assembly is installed on the car, the noise reduction microphone 216 is arranged at the driving position to facilitate the collection of the driver's voice commands. The upper end of the switch assembly controller 212 is provided with an image collector 214, which includes infrared and portrait lenses, and can detect the driver's face. When the driver performs voice control, it monitors the driver's mouth shape to determine his voice, and compares it with the collected voice data of the noise reduction microphone 216, and comprehensively corrects the driver's voice command of the terminal, and transmits it to the car system for execution, which solves the problem of low voice recognition accuracy.

[0042] Taking the light control switch as an example, when the driver turns the switch to different positions, the contacts inside the switch will close or open accordingly, thereby controlling the vehicle lights to be turned on or off. The working principle of the wiper control switch is similar. By controlling the operation of the wiper motor, different wiper speeds and intermittent times can be achieved.

[0043] The working principle of the steering wheel itself is to convert the driver's steering intention into the vehicle's driving direction. When the driver turns the steering wheel, the steering wheel transmits the rotation data to the car's steering control system through the steering mechanism, i.e., the steering machine 21. The steering control system works to drive the front wheels of the vehicle to rotate, thereby changing the vehicle's driving direction.

[0044] The embodiments of the present invention are given for the purpose of illustration and description, and are not intended to be exhaustive or to limit the invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art. The embodiments are selected and described in order to better illustrate the principles and practical applications of the present invention and to enable those of ordinary skill in the art to understand the present invention and thereby design various embodiments with various modifications suitable for specific uses.
