Description

Technical Field

[0001] The utility model belongs to the technical field of noise detection, in particular to a microphone sensor mounting bracket. Background Art

[0002] With the emergence of electric vehicles, people have higher and higher requirements for vehicle comfort, among which the judgment of the noise level inside the car has become an important criterion. As a test method for interior noise, the interior NVH test has been widely used.

[0003] When conducting noise testing, it is necessary to use a corresponding bracket to fix the microphone sensor at the corresponding position in the car. Among them, the noise test close to the driver's ear is particularly important. The existing technology mostly uses an adjustable angle bracket to rigidly connect the headrest support rod, or simply uses a strap to bind the microphone wearer to the headrest.

[0004] Although both of the above methods can complete the noise test in the car well, in actual use, due to the frequent bumps in the actual driving of the car, the bracket simply bound with a strap is not stable and is prone to falling off. The angle of the adjustable bracket is also easily changed due to bumps, causing the position of the microphone sensor to change, affecting the accuracy of the detection results. At the same time, when it is necessary to detect the noise in the back row, the above two methods often need to be reinstalled, which is inconvenient to operate. Utility Model Content

When it is necessary to test the noise of the ears of the front row occupants, turn the two L-shaped rods 6 upward with the rotating shaft 5 as the axis until the L-shaped rod 6 is embedded in the upper half of the groove 7, then rotate the twist rod 3, and tighten the flexible strap 2 by rotating the twist rod 3 until the mounting base 1 is tightly attached to the headrest, and then insert the two ends of the twist rod 3 into the corresponding limit clips 4 respectively. While fixing the flexible strap 2, the two L-shaped rods 6 can be locked, and then the two elastic bands 9 are tightened, and the corresponding hooks 10 are hung on the corresponding headrest support rods. Finally, the microphone sensor is installed in the corresponding clamping assembly, and the angle is adjusted to start the test.

[0030] The working principle and beneficial effects of the above technical solution are as follows: untie the twist rod 3, and then rotate the two L-shaped rods 6 with the rotating shaft 5 as the axis, so that the two L-shaped rods 6 are respectively embedded in the lower half of the groove body of the slide groove 7, and fix it by the friction force of the rubber pad 8, and then tighten the twist rod 3 again, so that the noise in the rear row can be detected.

[0031] In one embodiment, the number of rubber pads 8 in each slide groove 7 is set to two, and the two rubber pads 8 are symmetrically arranged.

[0032] The working principle and beneficial effects of the above technical solution are as follows: the two rubber pads 8 can further increase the friction between the two rubber pads 8 and the L-shaped rod 6, thereby fixing the L-shaped rod 6 more stably.

[0033] In one embodiment: a pair of symmetrically arranged elastic bands 9 are fixedly connected to the lower side of the mounting seat 1 , and a hook 10 is fixedly connected to one end of each elastic band 9 away from the mounting seat 1 .

[0034] The working principle and beneficial effects of the above technical solution are: tighten the elastic band 9 and hook the hooks 10 on the two headrest support rods respectively, so as to further improve the stability of the mounting seat 1.

[0039] In one embodiment, a side of the mounting seat 1 facing away from the twisting rod 3 is processed into a curved surface.

[0040] The working principle and beneficial effect of the above technical solution are as follows: by performing curved surface treatment on the side of the mounting seat 1 away from the twist rod 3, it can be prevented from scratching the surface of the car seat headrest.

[0041] In one embodiment, both ends of the twisting rod 3 are provided with anti-slip grooves.

[0042] The working principle and beneficial effects of the above technical solution are as follows: the provision of the anti-slip pattern can increase the friction between the twisting rod 3 and the user's hand, so that the user can twist the twisting rod 3 more stably.

[0043] Working principle and usage process:

[0044] First, fit the mounting base 1 to the back of the car seat headrest, then put the flexible strap 2 on the headrest. When it is necessary to test the noise of the ears of the front row occupants, turn the two L-shaped rods 6 upward with the rotating shaft 5 as the axis until the L-shaped rod 6 is embedded in the upper half of the slot 7, then rotate the twist rod 3, and tighten the flexible strap 2 by rotating the twist rod 3 until the mounting base 1 is tightly attached to the headrest, and then insert the two ends of the twist rod 3 into the corresponding limit clips 4 respectively. While fixing the flexible strap 2, the two L-shaped rods 6 can be locked, and then tighten the two elastic bands 9, and hang the corresponding hooks 10 on the corresponding headrest support rods. Finally, install the microphone sensor in the corresponding clamping assembly, adjust the angle and start the test.

[0045] When it is necessary to test the noise in the rear row, untie the twist rod 3, and then rotate the two L-shaped rods 6 with the rotating shaft 5 as the axis, so that the two L-shaped rods 6 are respectively embedded in the lower half of the groove body of the slide groove 7, and fix it with the friction force of the rubber pad 8, and then re-tighten the twist rod 3, and the noise in the rear row can be detected. The utility model adopts the technical means of cooperating with the flexible strap 2 and the twist rod 3. The flexible strap 2 is tightened by tightening the twist rod 3, so that the mounting seat 1 can be stably bound to the headrest of the car seat. At the same time, the twist rod 3 stuck in the limit clamp 4 locks the L-shaped rod 6, which can effectively avoid the position of the microphone sensor installed on the sensor clamping part from being offset, thereby overcoming the shortcomings of the prior art. Moreover, after rotating the L-shaped rod 6, the noise in the rear row can be tested, which further improves the practicality of the device.
