Description

Technical Field

[0001] The utility model relates to the field of automobile seat motor detection, in particular to an automobile seat motor noise detection room. Background Art

[0002] Electric vehicle seats are typically equipped with three or more motors, responsible for adjusting the seat in various directions and angles. During the seat adjustment process, the motor may produce high operating noise due to defects in the assembly process or its own quality, affecting the passenger's driving experience and causing customer complaints. Therefore, electric vehicle seats need to be tested for motor noise before leaving the factory. Finished car seats are usually placed in a soundproof testing room for testing. This requires the soundproof testing room to eliminate external noise as much as possible to provide a quiet environment for motor operation noise testing. The doors of noise testing rooms in the existing technology use a horizontally movable method to block the entrance and exit. This has the disadvantage that external noise can easily enter the room through the gap in the door, affecting the motor noise detection inside the room. Summary of the Invention

[0003] The present invention aims to solve the problems in the existing technology and develops a car seat motor noise detection room. The technical solution adopted by the present invention is: a car seat motor noise detection room, characterized in that it includes a room body 1, a soundproof door 2, an upper slide rail assembly 3, a lower slide rail assembly 4, an upper slide rail bracket 5, a buzzer 6, a button 23 and a recording microphone 24; the room body 1 is provided with an entrance and exit 9; the entrance and exit 9 are provided with a sealing frame 8 on the periphery; the soundproof door 2 is externally fixedly connected to a handle 7, in which a sealing ring 10 is provided; the upper slide rail bracket 5 is fixedly connected to the room body 1; the upper slide rail assembly 3 includes an upper left slide rail 17, an upper right slide rail 18 and an upper guide rail 19; the upper right slide rail 18 and the upper guide rail 19 are respectively fixedly connected to the upper slide rail bracket 5; the upper left slide rail 17 is slidably connected to the upper guide rail 19; the upper guide rail baffle 20 is fixedly arranged at the outer end of the upper guide rail 19; the lower rail assembly 4 includes a lower left rail 11, a lower right rail 12 and a lower rail 15; the lower right rail 12 and the lower rail 15 are respectively fixedly connected to the ground; the lower left rail 11 is slidingly connected to the lower guide rail 15; the left baffle 13 is fixedly arranged at the left end of the lower left rail 11; the right baffle 14 is fixedly arranged at the right end of the lower right rail 12; the lower guide rail baffle 16 is fixedly arranged at the outer end of the lower guide rail 15; the soundproof door 2 can slide along the upper left rail 17, the upper right rail 18, the lower left rail 11 and the lower right rail 12; the buzzer 6 is electrically connected to the button 23; the recording microphone 24 is fixedly arranged on the inner wall of the room body 1.

[0004] The benefits of the present invention are as follows: since there is a sealing frame on the periphery of the inlet and outlet of the room body, a sealing ring is provided inside the soundproof door. When the soundproof door slides to the outside of the inlet and outlet, it cooperates with the guide rails provided on the upper and lower sides to push the soundproof door toward the inlet and outlet. The sealing ring inside the soundproof door fits tightly with the sealing frame of the room body, effectively preventing external noise from entering the room body through the door gap, ensuring a quiet environment of the room body, and facilitating improved detection accuracy during operation of the seat motor.

The function of left baffle 13, right baffle 14 is to prevent the soundproof door 2 from derailing. Figure 2 From the right side of the room body 1, the soundproof door 2, the upper slide rail assembly 3, the lower slide rail assembly 4, the upper slide rail bracket 5, the handle 7 and the sealing ring 10 of the present invention are displayed. Figure 3 and Figure 4 The upper guide rail baffle 20 and the lower guide rail baffle 16 prevent the sound insulation door 2 from slipping off from the upper guide rail 19 and the lower guide rail 15. Figure 3 The soundproof door 2 slides to the position of the upper right slide rail 18 and the lower right slide rail 12, and the entrance and exit 9 are open. Figure 4 This is a schematic bottom view of the upper rail assembly 3.
