[0017] Combination Figure 1 , Figure 2 , Figure 3 and Figure 4 A noise testing device for new energy vehicles includes a base 1, with a sound-collecting device 2 connected to the top of the base 1. The sound-collecting device 2 collects noise for subsequent data analysis. The base 1 has first threaded grooves 7 on both sides, which are used to adjust the height of a threaded rod 3, thereby changing the height of the sound-collecting device 2 or adapting to different seats. A threaded rod 3 is connected inside the first threaded grooves 7, supporting the base 1. A grip 4 is connected to one side of the threaded rod 3, facilitating rotation of the threaded rod 3 and connecting to a baffle 5. A baffle 5 is connected to the outer side of the grip 4, engaging with the backrest to prevent detachment. The side of the seat 1 is provided with an insertion slot 9, which facilitates the connection of the radio device 2. A locking block 8 is provided on the outside of the insertion slot 9 to quickly fix the radio device 2 and prevent it from falling off. A rubber layer 11 is connected to the bottom of the radio device 2 to absorb shock and prevent vibration from affecting the accuracy of the test results. An insertion rod 10 is connected to the center of the radio device 2. The insertion rod 10 is inserted into the insertion slot 9 to complete the fixing work. A second threaded groove 13 is provided in the center of the baffle 5 to facilitate the connection of the grip block 4 and prevent the baffle 5 from falling off. Soft pads 12 are connected to the upper and lower sides of the baffle 5 to prevent the baffle 5 from squeezing the seat and causing wear on the seat surface.

[0018] The present invention will be further described below with reference to the embodiments.

[0019] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The device base 1 also has a storage slot 6 in the center. The storage slot 6 is connected to the baffle 5 by an interference fit. There are two storage slots 6. The baffle 5 is stored in the storage slots 6 so that it can be placed conveniently when not in use. The threaded rod 3 is connected to the first threaded groove 7 by a threaded connection. The threaded rod 3 is connected to the grip 4 by a fixed connection. The other side of the grip 4 is provided with a threaded protrusion. The position of the grip 4 is changed by the cooperation of the threaded rod 3 and the first threaded groove 7, thereby adjusting the height of the radio device 2.

[0020] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The bottom of the receiver 2 is evenly and equidistantly distributed with rubber layers 11. The receiver 2 is fixedly connected to the insertion rod 10. The insertion rod 10 is located at the center of the circular groove. The insertion rod 10 cooperates with the rubber layers 11 to prevent the vibration of the equipment base 1 and the receiver 2 from generating noise that affects the accuracy of the test results. The locking block 8 is fixedly connected to the equipment base 1. The locking block 8 is interference-fitted to the receiver 2. The receiver 2 forms a sliding connection structure with the insertion rod 10 and the insertion groove 9. The receiver 2 is quickly fixed by cooperating with the insertion rod 10. The soft pads 12 are symmetrically distributed on both sides of the center of the baffle 5. The center of the baffle 5 coincides with the center of the second threaded groove 13. The second threaded groove 13 is threadedly connected to the threaded protrusion. The baffle 5 fixes the gripping block 4 to prevent the equipment base 1 from moving.

[0021] Working principle: First, when ground noise testing is required, rotate the grip block 4, causing the grip block 4 to drive the threaded rod 3 to rotate, and the threaded rod 3 and the grip block 4 to move in the first threaded groove 7. This changes the position of the threaded rod 3 and the grip block 4 until the appropriate length is reached. Then, remove the baffle 5 from the storage slot 6 and rotate the baffle 5 so that the second threaded groove 13 in its center is threadedly connected to the threaded protrusion in the center of the grip block 4. At this time, the baffle 5 is placed against the ground to support the grip block 4 and the equipment base 1. The sound recording device 2 can be placed on the locking block 8 on the side of the equipment base 1 and pressed so that the insertion rod 10 is inserted into the insertion slot 9. At the same time, the locking block 8 and the sound recording device 2 are locked together and fixed. When a car passes by, the sound recording device 2 collects the car noise data for subsequent testing. As described above, when seat testing is required, first place the device base 1 above the car seat. If there is a gap between the backrest and the seat cushion, rotate the handle 4 so that the threaded rod 3 passes through the gap and extends from behind the backrest. At this time, push the device base 1 so that it fits against the front side of the backrest. Then take out the baffle 5 and connect it with the handle 4 so that the baffle 5 fits against the back side of the backrest. At this time, place the microphone 2 in the locking block 8 and insertion slot 9 above the center of the device base 1. When the car is moving, the device base 1 and the baffle 5 are close to the two sides of the backrest to ensure that the microphone 2 is fixed. The rubber layer 11 also provides shock absorption and cushioning for the bottom of the microphone 2 to prevent noise from affecting the accuracy of the test results. If the seat cushion is an integrated structure without gaps, the threaded rod 3 can fit against the two sides of the backrest, and the baffle 5 can be placed horizontally.
