[0002] The voice control device on the car steering wheel is one of the important interactive functions of modern smart cars. It helps drivers operate vehicle functions more safely and conveniently through voice commands. It consists of multiple core components and auxiliary components that work together to realize the voice interaction function.

[0003] Existing technologies, such as the utility model application with application number 201320138597.7, disclose a voice-controlled steering wheel and vehicle. To address this issue, existing vehicles place many function control buttons on the center console. However, this structure requires the driver to take their hands off the steering wheel to control the vehicle, distracting the driver and creating safety hazards. Furthermore, the complex center console design increases vehicle costs. The proposed solution uses a voice receiving module mounted on the steering wheel to receive user-input voice commands. These commands are then interpreted into control instructions by a voice recognition module and controlled by the main control module to operate the vehicle's electronic systems accordingly. This reduces driver interference and facilitates vehicle operation.

[0004] The above-mentioned applications still have shortcomings:

[0005] In actual use, due to the small size of the microphone hole, if the driver does not pay attention to hand hygiene, the microphone hole can easily become blocked during long-term driving, causing the voice control device to fail to be activated by voice and affecting the use of the device.

[0006] To address this issue, a voice control device for the steering wheel was designed. Utility Model Content

[0026] Example 1

[0027] like Figure 1 , Figure 2 , Figure 3 and Figure 4As shown, this embodiment proposes a voice control device for a steering wheel, including a steering wheel 1, a microphone hole 3 on the steering wheel 1, a voice receiving module 4 located below the microphone hole 3, a voice input key 2 for waking up the voice receiving module 4, a voice recognition module for parsing voice, and a controller module for controlling the vehicle according to the parsed instructions. Voice control is an important interactive function of modern intelligent vehicles. The voice recognition module can be located inside the steering wheel 1 module, or it can be installed in the control unit below the instrument panel or the center console. The controller module is usually located behind the center screen or below the instrument panel. The installation positions of the voice recognition module and the controller module are existing technologies, so this application will not elaborate further. The steering wheel 1 has a mounting groove 5. A pressure cover 6 is vertically slidably installed inside the mounting groove 5. A first spring 7 is provided between the bottom end of the pressure cover 6 and the inner bottom of the mounting groove 5. The microphone hole 3 is located in the middle of the pressure cover 6. The pressure cover 6 has a cleaning mechanism for cleaning the inside of the microphone hole 3.

[0028] When microphone hole 3 is blocked, press the cover 6 downward with your finger. As the cover 6 moves downward, it compresses the first spring 7. At this time, the conveying mechanism will extend upward from the bottom of microphone hole 3 to lift the blockage inside microphone hole 3. Then, use your finger to remove the blockage or blow it away. Release the cover 6 and reset it under the force of the first spring 7. At this time, microphone hole 3 is open.

[0029] Example 2

[0030] The solution in Example 1 will be further described below with reference to its specific working method.

[0031] like Figure 1 As shown, in a preferred embodiment, based on the above method, the unblocking mechanism further includes a trumpet-shaped guide channel 8, a top block 9, and a translational reset assembly. The trumpet-shaped guide channel 8 is located at the bottom of the microphone hole 3. The top blocks 9 are evenly distributed in a circular array below the trumpet-shaped guide channel 8. The top of the top block 9 is in contact with the top surface of the trumpet-shaped guide channel 8. The mounting groove 5 is equipped with a translational reset assembly to control the movement of the top block 9. The tilt angle of the guide channel 8 is 45°. The top of the top block 9 is provided with an arc surface that matches the guide channel, and the contact area is not less than 30% of the surface area of ​​the top block. The top block 9 is made of aluminum alloy and the surface is anodized with a hardness ≥150HV. During the process of pressing down the pressure cap 6, the top block 9 is limited by the translational reset mechanism, so the top block 9 can only move in a straight line. The top of the top block 9 moves upward along the trumpet-shaped guide channel 8 and extends out from the microphone hole 3 to push out the blockage.

[0032] like Figure 1As shown, in a preferred embodiment, based on the above method, the top block 9 is further provided in four sets, and the shape of the top block 9 is a quarter cylinder. Multiple sets of top blocks 9 fit together to form a cylinder, and the outer diameter of the cylinder is the same as the inner diameter of the microphone hole 3. Multiple sets of top blocks 9 form a cylinder during the upward movement and extend out of the microphone hole 3, which can ensure the cleaning effect inside the microphone hole 3.

[0033] like Figure 1 As shown, in a preferred embodiment, based on the above method, the translational reset assembly further includes a fixing ring 10, a sliding rod 11, and a second spring 12. The fixing ring 10 is fixed to the inner bottom of the mounting groove 5. The sliding rods 11 are evenly slidably arranged in a ring array on the fixing ring 10, and the sliding rods 11 are perpendicular to the tangential direction of the fixing ring 10. The ends of the sliding rods 11 are respectively fixedly connected to the top block 9. The second spring 12 is provided between the outer side of the top block 9 and the inner side of the fixing ring 10. When the pressure cover 6 is pressed, the horn-shaped guide groove 8 will apply a pushing force to the top block 9 toward the microphone hole 3. Due to the limiting effect of the sliding rod 11, the top block 9 will slide in a straight line, and after it comes into contact with other top blocks 9, it will extend out of the microphone hole 3.

[0034] like Figure 1 As shown, in a preferred embodiment, based on the above method, the slide rod 11 passes through the inside of the second spring 12, and the fixing ring 10 is provided with a sliding hole that cooperates with the slide rod 11. By using the slide rod 11, the second spring 12 can be limited.

[0035] Example 3

[0036] The solutions in Embodiments 1 and 2 will be further described below with reference to their specific working methods.

[0037] When microphone hole 3 is blocked, press down on the pressure cap 6 with your finger. As the pressure cap 6 moves down, it compresses the first spring 7. The flared guide groove 8 will apply a pushing force to the top block 9 towards microphone hole 3. Due to the limiting effect of the slide rod 11, the top block 9 will slide in a straight line until it is in contact with other top blocks 9, and then it will extend out of microphone hole 3. Since the cylinder formed by the top blocks 9 after they are in contact with each other has the same inner diameter as microphone hole 3, the top block 9 can completely lift up the blockage inside microphone hole 3. Then, use your finger to remove the blockage or blow it away. After cleaning, release the pressure cap 6, and it will reset under the force of the first spring 7. At this time, microphone hole 3 is open.

[0038] The above description is only a further embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the scope disclosed by the present utility model, based on the technical solution and concept of the present utility model, shall fall within the protection scope of the present utility model.
