In order to solve this technical problem, an integrated adjustable active noise reduction driver's cab seat is proposed.

[0032] In conjunction with the accompanying drawings, some embodiments of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.

[0033] Example 1 See also Figures 1 to 5 , a structural diagram of an integrated adjustable active noise reduction driver's cab seat provided in Example 1 of the present invention, the integrated adjustable active noise reduction driver's cab seat comprising: a seat assembly and an active noise reduction device; the active noise reduction device comprises a controller and a noise reduction component; the seat assembly comprises a support frame 1 and an adjustment frame 3, the support frame 1 comprises a support portion, a cushion portion and a backrest portion, the support portion of the support frame 1 is sleeved with an installation box 5 on the outer side, and the controller is arranged inside the installation box 5; the cushion portion is provided with a cushion 7, and the backrest portion is sleeved with a backrest 4; a height-adjustable adjustment frame 3 is installed on the top of the back of the support frame 1, and the noise reduction component is installed on the backrest of the support frame 1; a headrest is arranged on the adjustment frame 3.

[0034] The driver's cab seat of the present invention has high integration and good integration, reduces the volume and increases the available space of the driver's cab. The controller is installed under the seat and does not need to occupy the control cabinet space in the driver's cab. The controller is arranged inside the installation box 5, which can reduce unnecessary mechanical parts and electrical connector components, reduce manufacturing costs, and reduce the failure rate.

[0035] The backrest 4 is also provided with an active noise reduction switch 2 , and the active noise reduction switch 2 is communicatively connected with the controller.

[0036] The noise reduction component includes a microphone sensor and a speaker, and both the microphone sensor and the speaker are electrically connected to the controller.

[0037] Specifically, the active noise reduction device receives and determines the noise through the microphone sensor to form a noise signal. The generated signal is transmitted to the built-in controller under the driver's cab seat assembly through the built-in circuit. The built-in controller analyzes and processes the noise and generates a control signal with a phase opposite to the original noise sound wave signal. The control signal outputs the sound wave through the speaker to offset the noise in the driver's head range of movement, thereby improving the acoustic level of the driving position area in the driver's cab. The driver and passengers can turn on and off the active noise reduction by operating the active noise reduction switch 2 according to the noise generated by the driving route.

[0038] like Figure 1 As shown, as a preferred embodiment of the present invention, the installation box 5 is provided with an inspection door 6, and the inspection door 6 is provided to facilitate the inspection of the controller.

[0039] like Figure 1 As shown, as a preferred embodiment of the present invention, the support frame 1 is also provided with a front and rear adjustment device 10 and a backrest adjustment device 8. The front and rear adjustment device 10 and the backrest adjustment device 8 are prior art and will not be described in detail.

[0042] In some other embodiments, the speaker includes a speaker body, a speaker processor and a power module. The crossbar 33 is used to install the speaker processor and the power module, wherein the speaker processor is used to control the speaker to output sound waves, and the power module is used for partial power supply needs. The mounting plate 32 is used to install the speaker body and the microphone sensor.

Both sides of the handle structure 31 are provided with a plurality of dot-shaped protrusions 36, and the dot-shaped protrusions 36 are used to abut against the inner groove 37, so as to facilitate the position of the handle structure 31. When the position of the handle structure 31 needs to be adjusted, the height adjustment is achieved by pulling the handle structure 31 up and down. The dot-shaped protrusions 36 can be spherical structures.
