Description

Technical Field

[0001] This utility model relates to the field of automotive seat airbag detection technology, and in particular to a noise testing device. Background Technology

[0002] The function of car seats has gradually expanded beyond simply providing a comfortable driving and riding posture. In high-end cars, designers have incorporated massage and ventilation functions into the car seats to meet the growing demands of consumers. Most car seat massage functions achieve this by inflating and deflating airbags within the seat.

[0003] For example, the car massage seat proposed in utility model patent application number CN201821964079.X, when the air pump and controller receive a signal from the control panel, the air pump turns on and inputs gas into the controller. Under the action of a pre-set program, the controller inputs the gas into the massage air bag through the air pipe in different ways, causing the massage air bag to inflate. The inflated part of the air bag compresses the back and waist of the driver or passenger, thereby completing the massage action, reducing driver fatigue, and thus improving comfort and safety.

[0004] Since the seat massage mechanism relies solely on the driver, while the airbags are controlled by an air pump and controller, noise testing of the seat massage mechanism is necessary to prevent excessive noise during operation from affecting the driver's experience. Utility Model Content

[0005] In view of this, it is necessary to provide a noise testing device to solve the problem of noise testing of seat massage structures.

The noise detection component 300 is disposed inside the test box 100 and has a pickup end for receiving sound signals.

[0024] During implementation, the seat massage structure is placed on the support platform 200 and turned on. The noise detection component 300 can detect the noise generated by the seat massage structure during operation, thereby determining whether the operating noise of the seat massage structure meets the requirements.

[0025] The test chamber 100 in this embodiment provides a closed environment for noise detection.

[0026] To facilitate the insertion and removal of the seat massage structure, in one embodiment, the test chamber 100 includes a chamber body 110 and a door 120. The door 120 is hinged to an opening on the side wall of the chamber body 110 for opening or closing the opening. The chamber body 110 and the door 120 are hinged via a hinge 111. To facilitate locking the door 120, the device also includes a locking block 112, which is rotatably connected to the chamber body 110 and can rotate to a position where it engages with the door 120 located in the opening. To facilitate opening and closing the door 120, the device also includes a handle 113 mounted on the door 120.

[0027] To reduce the transmission of noise from inside the test chamber 100 to the outside of the test chamber 100, in one embodiment, a sound insulation plate is fixedly disposed on the inner wall of the test chamber 100, and a plurality of pointed protrusions are formed on the sound insulation plate.

[0028] In this embodiment, the support platform 200 is used to support the seat massage structure. The support platform 200 is set inside the test box 100, and a snap-fit ​​station for fixing the seat massage structure is formed on the support platform 200.

[0029] It should be noted that the seat massage structure includes an air bag M1, a controller M2, and an air pump M3. To facilitate the fixing of the air bag M1, the controller M2, and the air pump M3, in one embodiment, a first snap-fit ​​station 210, a second snap-fit ​​station 220, and a third snap-fit ​​station 230 are formed on the support platform 200. The first snap-fit ​​station 210 is used to adapt and connect with the air bag M1, the second snap-fit ​​station 220 is used to adapt and connect with the controller M2, and the third snap-fit ​​station 230 is used to adapt and connect with the air pump M3.

[0030] The first snap-fit ​​station 210 includes four positioning pins fixed on the support platform 200. The four positioning pins pass through the four positioning holes at the four corners of the air bag M1 to fix the air bag M1.

[0031] The second carding station 220 and the third carding station 230 are card slots formed on the support platform 200, which can respectively embed the controller M2 and the air pump M3 into the two card slots.

[0032] After the air bag M1, controller M2 and air pump M3 are fixed in place, they can be connected through an air tube to complete the assembly process of the seat massage structure.

[0033] In one embodiment, a first air connector 240 and a second air connector 250 are further installed on the support platform 200. The first air connector 240 is located between the first snap-fit ​​station 210 and the second snap-fit ​​station 220, and the second air connector 250 is located between the second snap-fit ​​station 220 and the third snap-fit ​​station 230. The first air connector 240 and the second air connector 250 facilitate the connection process of the air pipes between the air bag M1, the controller M2, and the air pump M3.

[0034] In this embodiment, the noise detection component 300 is disposed inside the test chamber 100. The noise detection component 300 has a pickup end for receiving sound signals.

[0035] In one embodiment, the noise detection assembly 300 includes a microphone 310 and a bracket 320, with the microphone 310 fixedly mounted inside the test chamber 100 via the bracket 320. It is understood that the noise detection assembly 300 also includes a decibel meter connected to the microphone 310.

[0036] To adapt to the position of the driver's sensory organs relative to the seat massage structure, the position of the microphone 310 relative to the seat massage structure needs to be adjusted. In one embodiment, the bracket 320 includes a vertical rod 321, a connecting block 322, and a horizontal rod 323. The bottom end of the vertical rod 321 is fixedly connected to the support platform 200.
