The change or adjustment of their relative relationships, without substantial change in the technical content, should also be regarded as the scope within which this utility model can be implemented.

[0025] In order to be able to describe this utility model in detail, first, a specific description will be given to the bracket for installing a microphone of this utility model.

[0026] This application provides a bracket for installing a microphone, which includes a fixing component 1, an adjusting component 2, and a clamping component 3. The fixing component 1 is used to fix the bracket to the vehicle seat; the adjusting component 2 is installed on the fixing component 1, and the adjusting component 2 is used to adjust the position and angle of the microphone 4 on the fixing component 1; the clamping component 3 is installed on the side of the adjusting component 2 away from the fixing component 1 and is used to fix the microphone 4.

[0027] As Figure 1 shown, the fixing component 1 of this embodiment includes a connecting piece 11 and fixing pieces 12. The fixing pieces 12 are installed at both ends of the connecting piece 11. The connecting piece 11 is used to fix the fixing pieces 12 on both sides of the vehicle seat along the vehicle body width direction. In this embodiment, the fixing pieces 12 on both sides of the connecting piece 11 are respectively located on both sides of the vehicle seat width, and the extending direction of the connecting piece 11 is the vehicle body width direction. Of course, the connecting piece 11 can also be arranged along the front-back direction of the vehicle seat, but it is better to install the fixing pieces 12 in the vehicle seat width direction, so that the adjusting component 2 can be directly installed on the fixing pieces 12. After installation, the microphone 4 will be on the side of the vehicle seat. If the fixing pieces 12 are arranged along the vehicle body length direction, an L-shaped part needs to be set to convert the position of the microphone 4 so that the microphone 4 can be located on the side of the vehicle seat.

[0028] The fixing pieces 12 on both sides are formed by combining at least two fixing blocks 13, and adjacent fixing blocks 13 are hinged through a hinge 14. In this embodiment, for example Figure 1As shown, hinges 14 similar to hinges are used at the edges of the fixing blocks 13 to connect the fixing blocks 13, so that the bending degree of the fixing member 12 can be adjusted. The fixing member 12 is composed of a plurality of fixing blocks 13, and compared with an integral fixing member 12, it can adapt to car seats of different shapes.

[0029] Adjacent fixing blocks 13 can also be connected by universal rods, and universal balls are arranged on both sides of the universal rods. The universal rods can be arranged in the middle of adjacent fixing blocks 13, so that the position of the fixing member 12 can be adjusted at will. The headrest and the seat body of some existing car seats are integrated, and there is no metal rod between the headrest and the seat body. The position of the headrest is fixed relative to the car seat body and cannot be adjusted. Therefore, the fixing member 12 of this embodiment is arranged on both sides of the car seat, and is connected in the middle by a connecting member 11, instead of using the existing clip type to clamp the microphone on the metal rod of the headrest. In addition, some existing car seats are personalized in shape and are not standard. Therefore, by setting the fixing member 12 to be adjustable in angle, the bracket can be installed on car seats of various shapes.

[0030] Wherein, in order to be applicable to car seats of different widths, the connector 11 is designed as an elastic connector. The elastic connector can be made of elastic parts such as rubber bands and springs. The elastic bands are used, and the rigidity of the rubber bands is not very strong. The bracket shakes a lot during use, and the elasticity of the rubber bands after frequent expansion and contraction is not very good. For better effect and to extend the life of the bracket, the elastic connector of the present application adopts a coil spring. Each fixed block 13 on the left side can be connected to the corresponding fixed block 13 on the right side by a coil spring. Of course, some coil springs can be reduced as long as the fixed assembly 1 can be installed on the car seat.

[0031] In this embodiment, the left fixing member 12 and the right fixing member 12 are both provided with three fixing blocks 13. Of course, the number of fixing blocks 13 of the left fixing member 12 and the number of fixing blocks 13 of the right fixing member 12 may be the same or different. However, generally, the left and right sides of a car seat are symmetrical, so the number of fixing blocks 13 of the fixing members 12 on the left and right sides is the same.

[0032] The connecting member 11 fits the fixing member 12 to the car seat, so that the entire bracket does not move relative to the car seat as the car moves. The distance between the fixing members 12 on both sides is matched with the width of the car seat by adjusting the shape of the fixing block 13 to match the car seat, so that the stability of the fixing assembly 11 relative to the car seat is better.

[0033] To be applicable to vehicle seats of different widths, the helical spring and the corresponding fixed member 12 are connected by an adjusting rod 15. Generally, during testing, the microphone 4 is installed on the right ear at the driving position, and the adjusting rod 15 is arranged on the other side where the microphone 4 is installed, that is, the adjusting rod 15 is arranged on the left side of the driving position.

[0034] The fixing block 13 is made of plastic. To prevent the plastic from scratching the vehicle seat, a flannelette can be pasted on the side of the fixing block 13 close to the vehicle seat.

[0035] The adjusting rod 15 is installed on the fixed member 12. One end of the adjusting rod 15 is connected to the connecting member 11, and the other end is connected to the corresponding fixed member 12 on one side. The adjusting rod 15 is used to adjust the distance between the two fixed members 12. One end of the adjusting rod 15 is fixedly connected to the helical spring, and the other end is connected to the fixing block 13. By adjusting the position of the adjusting rod 15, the helical spring can be stretched accordingly to adapt to headrests of different widths.

[0036] Furthermore, the adjusting assembly 2 includes a base 21 and a support rod 22 connected to the base 21. The base 21 is arranged on one of the fixing blocks 13, and the position of the base 21 relative to the fixing block 13 can be changed. In this way, the position of the base 21 on the fixing block 13 can be adjusted, and thus the front-back, up-down position of the microphone 4 relative to the vehicle seat can be adjusted.

[0037] Specifically, a slider is provided on the side of the base 21 close to the fixing assembly 1, and an adjusting groove is provided on the fixing block 13. The slider is located inside the adjusting groove and can move within it. The edge of the adjusting groove can block the slider to prevent it from sliding out of the adjusting groove.

[0038] In order to enable the vehicle body to adjust its position not only in the vehicle body length direction but also in the vehicle body height direction, the adjusting groove in this embodiment includes a first sliding groove 16 and a second sliding groove 17 perpendicular to the first sliding groove 16. The first sliding groove 16 and the second sliding groove 17 are combined to form a cross-shaped adjusting groove.

[0039] As Figure 2 shown, at the intersection position between the first sliding groove 16 and the second sliding groove 17, the sliding direction of the adjusting assembly 2 can be changed. For example, when the slider is in the first sliding groove 16, the slider is horizontally arranged. When the slider needs to slide into the second sliding groove 17, the slider can be slid out of the first sliding groove 16 and then slid back into the second sliding groove 17. It is also possible to slide the slider to the intersection position between the first sliding groove 16 and the second sliding groove 17 and then slide the slider horizontally, and the slider can then slide into the second sliding groove 17. The slider can be set in a cross shape, or it can be square or rectangular. The widths of the first sliding groove 16 and the second sliding groove 17 can be the same or different.

[0040] When the slider slides in the first chute 16, the position of the base 21 is changed along the vehicle body height direction. When the slider slides along the second chute 17, the position of the base 21 is changed along the vehicle body length direction.

[0041] Fasteners are provided on the base 21. The fasteners are used to fix the base 21 in the adjustment groove so that the base cannot slide. The fasteners in this embodiment are limit bolts 23. After the position of the base 21 is adjusted, the limit bolts 23 are tightened. The limit bolts 23 contact the fixing member 12. For example, when the slider is located in the first chute 16 arranged along the vehicle body height direction, the limit bolts 23 are tightened. The frictional force between the limit bolts 23 and the bottom of the fixing block 13 is greater than the gravity of the support rod 22, and the slider will not slide down. When the slider is located in the second chute 17 along the vehicle body length direction, although the slider will not slide along the vehicle body height direction, in order to prevent the vehicle from changing its position during driving, after the limit bolts 23 are tightened, the slider cannot move back and forth. Of course, other methods can also be used to fix the base 21 on the fixing block 13.

[0042] To facilitate recording the position of the microphone 4 during each test, scales 18 can be provided on the edges of the first chute 16 and the second chute 17. After each adjustment, the coordinate position of the microphone 4 can be recorded.

[0043] In this embodiment, two mutually perpendicular chutes are provided on the fixing block 13, and the position of the microphone 4 is changed by the sliding arrangement of the chutes and the slider. A number of fixing holes can also be provided on the fixing block 13. The fixing holes are arranged in a circular matrix or a square matrix. The base 21 is fixed to the fixing holes by bolts, and in this way, the position adjustment of the microphone 4 can also be achieved. The adjustment groove can also be designed to be circular.

[0044] The fixing block 13 provided with the adjustment groove can be different from other fixing blocks. For example, the length and width of the fixing block 13 designed with the adjustment groove can be made larger, and the length and width of the remaining fixing blocks 13 can be made smaller.

[0045] Among them, the support rod 22 is rotationally connected to the base 21 through a universal ball. After the position of the base 21 is fixed, the orientation of the microphone 4 is adjusted through the universal ball. The support rod 22 can also be set to be adjustable in length. Furthermore, the position of the microphone 4 in the XYZ three axes is realized through the support rod 22, the first chute 16, and the second chute 17, and the orientation of the microphone 4 is adjusted through the universal ball.

[0046] Specifically, the microphone 4 is installed on the clamping assembly 3. The clamping assembly 3 is provided with connection holes for connecting with the support rod 22. The upper part of the clamping assembly 3 can be an elastic semi-circular clip, as long as it can clamp the microphone 4 tightly. Existing clips can be used, such as Figure 3 as shown.

[0047] Working process: When installing the bracket on the vehicle seat, loosen the adjusting rod 15 and the fixing member 12, pass the bracket through one side of the vehicle seat, connect the adjusting rod 15 with the fixing block 13 on the other side in the width direction of the vehicle seat, adjust the fixing block 13 according to the shape of the vehicle seat so that the shape of the adjusted fixing member 12 matches the shape of the vehicle seat, then adjust the position of the base 21 as needed, tighten the limit bolt 23 after adjustment, record the coordinates of the base 21, place the microphone 4 on the clamping assembly 3 and clamp it, and adjust the angle of the support rod 22 relative to the base 21 as needed.

[0048] The above embodiments are only illustrative of the principles and effects of the present invention and are not intended to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical idea disclosed by the present invention should still be covered by the claims of the present invention.
