Technical Field
[0001] The present application relates to the technical field of anechoic chambers, and more specifically, to an L-shaped sound-absorbing structure for a vehicle. Background Art
[0002] In order to meet the sound absorption requirements, a large number of sound-absorbing structures are usually installed in the anechoic chamber. However, sometimes the test piece is large and needs to be lifted by a crane, so a crane needs to be installed in the anechoic chamber.
[0003] The car is made of metal. When the sound reaches the metal, it will produce reflected sound, which will affect the acoustic performance of the anechoic chamber. In order to avoid sound reflection, a certain thickness of sound-absorbing material is usually pasted on the metal surface. However, due to the uneven surface of the car or the complex structure of the car, most metal surfaces cannot be pasted to the sound-absorbing material. Therefore, this solution cannot fundamentally solve the problem of sound reflection.
[0004] In order to solve the above problems, the present application provides an L-shaped sound absorption structure for vehicles. Utility Model Content

[0009] With the above technical solution, by providing a knob, the connecting rod can be easily rotated, so as to facilitate the adjustment of the angles of the two positioning blocks at a later stage.
[0010] Furthermore, the four knobs are respectively located inside the four grooves, square blocks are embedded inside the outer sides of the four knobs, and connecting plates are fixedly connected to the outer sides of the four square blocks.
[0011] Through the above technical solution, by providing the square block, the knob can be positioned to prevent the connecting rod from rotating.
[0012] Furthermore, springs and telescopic rods are fixedly embedded between the four connecting plates and the two L-shaped sound absorbing bodies, and the four springs are respectively located on the outsides of the four telescopic rods.
[0013] Through the above technical solution, by arranging the spring, the overall flexibility of the structure during operation can be improved.
[0014] Furthermore, a magnet ring 1 is fixedly embedded in the four L-shaped sound absorbing bodies, and a magnet ring 2 is provided inside the four magnet rings 1.

[0017] Furthermore, the front sides of the two L-shaped sound absorbers are each provided with a T-shaped groove, and the rear sides of the two L-shaped sound absorbers are each fixedly connected with a T-shaped plate.
[0018] Through the above technical solution, multiple L-shaped sound absorbers can be easily installed and spliced by cooperating with the T-shaped plate and the T-shaped slot.
[0019] In summary, this application has the following beneficial technical effects:
[0020] During use, auxiliary components can be used to quickly complete the installation and fixation between multiple L-shaped sound absorbers and multiple steel structures. Since L-shaped sound absorbers are provided on both sides of the steel structure, a certain space is left between the L-shaped sound absorbers on both sides so as not to affect the operation of the vehicle.

[0030] Example:
[0031] The present application discloses an L-shaped sound absorbing structure for vehicles. Figure 1 、 Figure 2 、 Figure 3 and Figure 4 , comprising a steel structure 1, a connecting mechanism being provided on the outside of the steel structure 1, and the connecting mechanism extending into the interior of the steel structure 1;
[0032] The connecting mechanism includes a driving track 2, which is fixedly connected to the top inner wall of the steel structure 1. A driving track 3 is provided on one side of the driving track 2, and the driving track 3 is located inside the steel structure 1. L-shaped sound absorbers 4 are provided on both sides of the steel structure 1. Two connecting grooves are provided on the front and rear sides of the steel structure 1, and the four connecting grooves are symmetrically arranged in pairs with the center line of the steel structure 1 as the axis. The two L-shaped sound absorbers 4 are provided with grooves on the front and rear sides, and the two grooves are symmetrically arranged with the center line of the L-shaped sound absorber 4 as the axis. Connecting rods 5 are provided inside the four connecting grooves, and two positioning blocks 6 are fixedly sleeved on the outer sides of the inner ends of the four connecting rods 5. The outer ends of the four connecting rods 5 extend into the four grooves respectively.
[0033] See also Figure 4 , the four connecting rods 5 are provided with auxiliary components on the outside, and the auxiliary components include four knobs 7, the four knobs 7 are fixedly connected to the outer ends of the four connecting rods 5 respectively, the four knobs 7 are respectively located inside the four grooves, and the outsides of the four knobs 7 are embedded with square blocks 8, and the outsides of the four square blocks 8 are fixedly connected with connecting plates 9. By providing the knobs 7, it is easy to rotate the connecting rod 5, so as to adjust the angles of the two positioning blocks 6 in the later stage. At the same time, by providing the square blocks 8, the knobs 7 can be positioned to prevent the connecting rod 5 from rotating.
[0034] See also Figure 3 and Figure 4 , springs 10 and telescopic rods 11 are fixedly embedded between the four connecting plates 9 and the two L-shaped sound absorbing bodies 4, and the four springs 10 are respectively located on the outside of the four telescopic rods 11. A magnet ring 12 is fixedly embedded inside the four L-shaped sound absorbing bodies 4, and a magnet ring 13 is provided inside the four magnet rings 12. By providing the springs 10, the overall flexibility of the structure during operation can be improved. At the same time, the cooperation between the magnet ring 12 and the magnet ring 2 13 can be used to position the square block 8, thereby improving the operating efficiency.
[0035] See also Figure 2 、 Figure 3 and Figure 4 The four magnet rings 13 are respectively fixedly connected to the outside of the four connecting plates 9, and the four magnet rings 13 are respectively sleeved on the outside of the four springs 10. The front sides of the two L-shaped sound absorbers 4 are provided with T-shaped slots, and the rear sides of the two L-shaped sound absorbers 4 are fixedly connected with T-shaped plates 14. By matching the T-shaped plates 14 with the T-shaped slots, multiple L-shaped sound absorbers 4 can be easily installed and spliced.
[0036] The implementation principle of this embodiment is as follows: when in use, the installation between multiple L-shaped sound absorbers 4 can be completed by first cooperating with two T-shaped slots and two T-shaped plates 14, and then the connecting plates 9 on the outside of the head and tail L-shaped sound absorbers 4 are pulled in turn. According to the principle of opposite poles attracting each other, the magnet ring 12 and the magnet ring 2 13 are in a fit state, and the suction force here is greater than the elastic force of the spring 10. At this time, the spring 10 is in a compressed state, and the telescopic end of the telescopic rod 11 is in a retracted state. When the square block 8 is disengaged from the knob 7, the knob 7 can be rotated to rotate the two positioning blocks 6 ninety degrees. When the two positioning blocks 6 are rotated ninety degrees, the two positioning blocks 6 can be driven by the connecting rod 5 to extend to the inside of the connecting groove. When the knob 7 is in contact with the steel structure 1 After closing, the connecting rod 5 can be rotated again to rotate the two positioning blocks 6 ninety degrees, and then the connecting plate 9 is pushed. When the magnet ring 12 is separated from the magnet ring 2 13, the spring 10 will rebound and push the connecting plate 9. As the connecting plate 9 moves, the square block 8 will extend into the inside of the knob 7, so that the knob 7 is in a positioned state. Through the above structure, the installation and fixation between multiple L-shaped sound absorbers 4 and multiple steel structures 1 can be quickly completed. Because L-shaped sound absorbers 4 are provided on both sides of the steel structure 1, a certain space is left in the middle of the L-shaped sound absorbers 4 on both sides so as not to affect the operation of the carriage 3. Therefore, the carriage 3 and the track can be covered by the L-shaped sound absorber 4, so that the anechoic chamber is not affected by the reflected sound of the carriage 3, and the acoustic performance of the anechoic chamber is guaranteed.
[0037] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
