Description

Technical Field

[0001] This invention relates to the field of automotive parts technology, specifically to an airborne shock absorption device. Background Technology

[0002] With the widespread adoption of new energy electric vehicles, they have brought great convenience and entertainment to people's lives. Compared to traditional fuel vehicles, new energy electric vehicles significantly reduce interior noise because they use electric motors instead of engines. However, with the continuous improvement of vehicle electronic equipment configurations, the application of electric flip screens in the central control multimedia navigation interface is increasing. During the raising, lowering, and automatic folding of the flip screen, the power transmission of the electric motor generates relatively high operating noise and abnormal sounds, which seriously affects the user experience.

[0003] Therefore, this application studies an airborne vibration damping device that can significantly reduce noise and abnormal sounds generated by vibration, thereby improving the quality of the in-vehicle acoustic environment and enhancing the user experience. Utility Model Content

[0004] In order to reduce noise and abnormal sounds generated by vibration, thereby improving the quality of the in-vehicle acoustic environment and enhancing the user experience, this application provides an airborne vibration damping device.

[0005] This application provides an airborne shock absorption device, which adopts the following technical solution:

[0006] An airborne shock absorption device includes two motors, a control system, and a power conversion component. The two motors are connected to the power conversion component, which is used to convert the output power. The control system controls the two motors to produce opposite output phases, so that the sound amplitudes cancel each other out.

[0007] By adopting the above technical solution, the control system precisely controls the drive of the motor, so that the output phases of the two motors are opposite. When the vibrations generated by the two motors are completely opposite in phase, they can cancel each other out during the vibration transmission process, which greatly reduces the vibration amplitude of the device, thereby reducing operating noise, improving the quality of the in-vehicle sound environment, and improving the user experience.

[0008] Optionally, the two motors are a first motor and a second motor, and the control system controls the first motor to output a 0° phase and the second motor to output a 180° phase.

[0009] Optionally, the control system includes an MCU, a first motor drive module, and a second motor drive module. The MCU controls the first motor drive module to drive the first motor to output at a 0° phase, and the MCU controls the second motor drive module to drive the second motor to output at a 180° phase.

[0010] Optionally, it also includes a mounting bracket, on which the power conversion component is mounted, and the first motor and the second motor are respectively connected to the two input ends of the power conversion component.

[0011] By adopting the above technical solution, the control system can easily and independently control each motor, achieving precise power distribution and phase control.

[0012] Optionally, the power conversion component is a speed reducer.

[0013] Optionally, the power conversion component has a connecting lug, the motor has a threaded hole, the bolt passes through the connecting lug and is screwed into the threaded hole, and the nut of the bolt abuts against the connecting lug.

[0014] By adopting the above technical solution, a stable connection between the motor and the power conversion component is ensured, providing not only sufficient mechanical strength but also allowing for convenient installation and disassembly.

[0015] Optionally, the power conversion component has clearance grooves on both sides, and the connecting ear portion is located in the clearance groove. When the bolt is connected to the motor, part of the bolt nut is located in the clearance groove.

[0016] By adopting the above technical solution, sufficient space is provided for the connecting bolts, so that the bolt nuts can be smoothly embedded in the grooves during connection, thereby optimizing the internal spatial layout of the device.

[0017] Optionally, it may also include a screw connected to the output end of the power converter.

[0018] By adopting the above technical solution, the rotational power of the motor is transmitted to the screw through the power conversion component, realizing efficient power transmission and conversion. This enables the device to convert rotational motion into linear motion, making it suitable for various application scenarios and improving the applicability and flexibility of the device.

[0019] In summary, this application includes the following beneficial technical effects:

[0020] 1. The control system precisely controls the motor drive, so that the output phases of the two motors are opposite. When the vibrations generated by the two motors are completely opposite in phase, they can cancel each other out during the vibration transmission process, which greatly reduces the vibration amplitude of the device, thereby reducing operating noise, improving the quality of the in-vehicle sound environment, and improving the user experience.

[0021] 2. This enables the control system to easily and independently control each motor, achieving precise power distribution and phase control;

[0022] 3. It ensures a secure connection between the motor and the power conversion components, providing not only sufficient mechanical strength but also allowing for easy installation and disassembly. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-2 This application will be described in further detail.

[0029] This application discloses an airborne shock absorption device. (Refer to...) Figure 1 and Figure 2 The airborne vibration damping device includes two motors 1, a control system, and a power conversion component 2. Both motors 1 are connected to the power conversion component 2, which is used to convert the output power. In this embodiment, it is used to reduce the rotor speed and increase the torque to transmit power output. In some embodiments, it also includes a screw 3, which is connected to the output end of the power conversion component 2. The power conversion component 2 outputs power to the screw 3, achieving efficient power transmission and conversion. This allows the device to convert rotational motion into linear motion, making it suitable for various application scenarios and improving the applicability and flexibility of the device.

[0030] The control system controls two motors 1 to produce opposite output phases, and the sound amplitudes cancel each other out, so that the sound amplitude after cancellation can approach 0, thereby reducing operating noise, improving the quality of the in-vehicle sound environment, and improving the user experience.

[0031] In some embodiments, the two motors 1 are a first motor 11 and a second motor 12, respectively. The control system controls the first motor 11 to output a 0° phase and the second motor 12 to output a 180° phase. Because the phases are opposite, the vibrations they generate on the power conversion element 2 can cancel each other out, significantly reducing the overall vibration amplitude of the device.

[0032] In some embodiments, the control system includes an MCU, a first motor 11 drive module and a second motor 12 drive module. The MCU controls the first motor 11 drive module to drive the first motor 11 to output at a 0° phase, and the MCU controls the second motor 12 drive module to drive the second motor 12 to output at a 180° phase.

[0033] Reference Figure 2 In some embodiments, the airborne shock absorber further includes a mounting bracket 4, and the power conversion component 2 is screwed onto the mounting bracket 4. In some embodiments, the power conversion component 2 is a speed reducer. The first motor 11 and the second motor 12 are respectively connected to the two input ends of the power conversion component 2. In this embodiment, the first motor 11 and the second motor 12 are respectively connected to the two opposite sides of the power conversion component 2. The two motors 1 are connected to the speed reducer by their respective couplings or gears, which can realize the power combination of the two motors 1, making installation convenient.

[0034] In some embodiments, the power conversion component 2 has connecting lugs 5, the motor 1 has a threaded hole, and a bolt 6 passes through the connecting lugs 5 and is screwed into the threaded hole, with the nut of the bolt 6 abutting against the connecting lugs 5. One motor 1 corresponds to two connecting lugs 5, that is, the two opposite sides of the motor 1 are fixed, ensuring a stable connection between the motor 1 and the power conversion component 2, providing not only sufficient mechanical strength but also allowing for convenient installation and disassembly.

[0035] In some embodiments, the power conversion component 2 has relief grooves 7 on both sides. The relief grooves 7 are semi-cylindrical, and the arc shape of the relief grooves 7 matches the arc shape of the bolt 6. The connecting lug 5 is located in the relief grooves 7. When the bolt 6 is connected to the motor 1, half of the nut of the bolt 6 is located in the relief grooves 7. Sufficient space is provided for the connecting bolt 6 so that the nut of the bolt 6 can be smoothly embedded in the groove when connected, thereby optimizing the internal space layout of the device.

[0036] The implementation principle of an airborne vibration damping device according to an embodiment of this application is as follows: the control system precisely controls the drive of motor 1 so that the output phases of the two motors 1 are opposite. When the vibrations generated by the two motors 1 are completely opposite in phase, they can cancel each other out during the vibration transmission process, which greatly reduces the vibration amplitude of the device, thereby reducing operating noise, improving the quality of the in-vehicle sound environment, and improving the user experience.
