[0030] Embodiment 1

[0031] An intelligent road noise experimental detection device for automobiles, as Figure 1 and Figure 2 shown, includes a support frame 1, a first suction cup 2, a road noise detector 3, an adsorption mechanism 4, and a clamping mechanism 5. The road noise detector 3 is fixedly connected to the upper side of the support frame 1, and the road noise detector 3 can detect the noise of the automobile. The first suction cup 2 is connected to the right side of the support frame 1, and the first suction cup 2 can adsorb the support frame 1 on the wall. An adsorption mechanism 4 for adsorbing the intelligent road noise experimental detection device for automobiles on the wall is provided on the support frame 1, and a clamping mechanism 5 for clamping the adsorption mechanism 4 is provided on the support frame 1.

[0032] As Figure 1 and Figure 3As shown, the adsorption mechanism 4 includes a first piston rod 41, a first guide rod 42, and a pull rod 43. Two first guide rods 42 are welded between the left and right sides of the inner wall of the support frame 1. The two first guide rods 42 are symmetrically arranged up and down. A pull rod 43 is slidably connected between the two first guide rods 42. The first guide rod 42 can guide the pull rod 43. A first piston rod 41 is slidably connected inside the first suction cup 2. The left side of the first piston rod 41 is fixedly connected to the right side of the pull rod 43.

[0033] As Figure 1 and Figure 4 As shown, the clamping mechanism 5 includes a second guide rod 51, a clamping plate 52, a first spring 53, and a second spring 54. The upper and lower sides of the right inner wall of the support frame 1 are both connected with a second guide rod 51. Two clamping plates 52 are slidably connected between the second guide rods 51. The two clamping plates 52 are symmetrically arranged front and back. The second guide rod 51 can guide the clamping plate 52. The clamping plate 52 can clamp and limit the pull rod 43. A first spring 53 is connected between the mutually separated sides of the upper and lower parts of the clamping plate 52 and the second guide rod 51. The first spring 53 is wound around the second guide rod 51. The first spring 53 can make the clamping plate 52 move back to its original position. A second spring 54 is connected between the upper and lower sides of the right wall of the pull rod 43 and the right inner wall of the support frame 1. The second spring 54 is wound around the first guide rod 42. The second spring 54 can make the pull rod 43 move back to its original position. The left side of the pull rod 43 is arc-shaped, which can better squeeze the clamping plates 52 to move away from each other.

[0034] When people need to detect the noise of an automobile, this device can be used. First, people fit the first suction cup 2 to a smooth wall surface. Then, people pull the pull rod 43 to the left. At this time, the second spring 54 is stretched. The first guide rod 42 can guide the pull rod 43. The movement of the pull rod 43 to the left drives the first piston rod 41 to move to the left. The movement of the first piston rod 41 to the left can suck out the air between the first suction cup 2 and the wall surface, thereby enabling the first suction cup 2 to be adsorbed and fixed on the wall surface, and thus fixing this device on the wall surface. Subsequently, when the pull rod 43 contacts the clamping plate 52, since the left side of the pull rod 43 is arc-shaped, the pull rod 43 will squeeze the clamping plates 52 to move away from each other. At this time, the first spring 53 is compressed. Subsequently, when the pull rod 43 moves to the left side position of the clamping plate 52, the clamping plate 52 is released. The clamping plate 52 moves closer to each other and resets under the action of the first spring 53. Then people release the pull rod 43. The clamping plate 52 can play a role in clamping and limiting the pull rod 43, thereby preventing the pull rod 43 from automatically moving to the right and resetting. Subsequently, the road noise detector 3 can automatically detect the noise of the automobile, and it is not necessary for people to hold the road noise detector 3 by hand to detect the noise of the automobile, reducing the labor intensity of people. When the detection of the automobile noise is completed and people need to remove this device, first, people move the clamping plates 52 away from each other. At this time, the first spring 53 is compressed. The movement of the clamping plates 52 away from each other releases the pull rod 43. Then the pull rod 43 moves to the right and resets under the action of the second spring 54. The movement of the pull rod 43 to the right drives the first piston rod 41 to move to the right and reset, thereby reducing the suction force between the first suction cup 2 and the wall surface. Then people release the clamping plates 52. The clamping plates 52 move closer to each other and reset under the action of the first spring 53. Subsequently, people can remove this device. By repeating the above operations through the first suction cup 2, this device can be adsorbed and fixed on a smooth wall surface, so that it is not necessary for people to manually hold the road noise detector 3, and thus the noise of the automobile can be automatically detected, improving the noise detection efficiency. At the same time, the clamping plate 52 can play a role in clamping and limiting the pull rod 43, and thus can prevent the pull rod 43 from automatically moving to the right and resetting, so as to reduce the labor force of people.

[0035] Embodiment 2

[0036] On the basis of Embodiment 1, such as Figure 1 、 Figure 2 、 Figure 5 、 Figure 6 and Figure 7As shown in the figure, it further includes a support mechanism 6 for improving the stability of the intelligent road noise experimental detection equipment of this vehicle. The support mechanism 6 includes a third guide rod 61, a first L-shaped connecting rod 62, a third spring 63, a second L-shaped connecting rod, a T-shaped support rod 65 and a torsion spring 66. Third guide rods 61 are welded to the upper and lower sides of the left wall inside the support frame 1. First L-shaped connecting rods 62 are slidably connected to the third guide rods 61. The third guide rods 61 can guide the first L-shaped connecting rods 62. The right parts of the first L-shaped connecting rods 62 pass through the right side of the support frame 1, and the first L-shaped connecting rods 62 are slidably connected to the support frame 1. When the pull rod 43 moves to the left, it will contact the first L-shaped connecting rod 62. Third springs 63 are connected between the left sides of the first L-shaped connecting rods 62 and the left wall inside the support frame 1. The third springs 63 are wound around the third guide rods 61. The third springs 63 can make the first L-shaped connecting rods 62 move back to their original positions. T-shaped support rods 65 are rotatably connected to the right sides of the first L-shaped connecting rods 62. When the T-shaped support rods 65 rotate and contact the wall surface, it can improve the stability of this equipment. Second L-shaped connecting rods 64 are connected to the upper and lower sides of the right wall of the support frame 1. The second L-shaped connecting rods 64 can limit the T-shaped support rods 65. Torsion springs 66 are connected between the front and back sides of the T-shaped support rods 65 and the first L-shaped connecting rods 62. The torsion springs 66 are wound around the T-shaped support rods 65. The torsion springs 66 can make the T-shaped support rods 65 rotate back to their original positions.

[0037] When people need to improve the stability of this equipment, first, when the pull rod 43 moves to the left, the pull rod 43 will contact the first L-shaped connecting rod 62 when it moves to the left. When the pull rod 43 continues to move to the left, it will drive the first L-shaped connecting rod 62 to move to the left. At this time, the third spring 63 is compressed. The third guide rod 61 can guide the first L-shaped connecting rod 62. The first L-shaped connecting rod 62 moving to the left drives the T-shaped support rod 65 to move to the left. Since the second L-shaped connecting rod 64 abuts against the T-shaped support rod 65, the T-shaped support rod 65 will rotate to the right. At this time, the torsion spring 66 is twisted. The T-shaped support rod 65 rotating to the right will abut against the wall surface, thereby improving the stability of this equipment and preventing the equipment from falling due to insufficient suction of the first suction cup 2. After that, the vehicle noise can be detected. After the detection is completed, and when the pull rod 43 moves back to the right, the pull rod 43 moving to the right releases the first L-shaped connecting rod 62. Then, the first L-shaped connecting rod 62 moves back to the right under the action of the third spring 63. The first L-shaped connecting rod 62 moving to the right pushes the T-shaped support rod 65 to move to the right. When the T-shaped support rod 65 separates from the second L-shaped connecting rod 64, the T-shaped support rod 65 rotates back to the left under the action of the torsion spring 66. Then people can remove this equipment. Repeating the above operations, by rotating the T-shaped support rod 65 to the right to abut against the wall surface, the stability of this equipment can be improved, and further, the situation that this equipment falls due to insufficient suction of the first suction cup 2 can be prevented.

[0038] Such asFigure 1 , Figure 8 and Figure 9 As shown, it also includes a pressurizing mechanism 7 for pressurizing the first suction cup 2, and the pressurizing mechanism 7 includes an L hollow rod 71, a second piston rod 72, a fourth spring 73 and a limiting rod 74. The L hollow rod 71 is fixedly connected to the rear side of the first suction cup 2, and the second piston rod 72 is slidably connected to the L hollow rod 71. A fourth spring 73 is connected between the right side of the second piston rod 72 and the inner wall of the L hollow rod 71. The fourth spring 73 can move and reset the second piston rod 72. The limiting rod 74 is connected to the left side of the second piston rod 72, and the limiting rod 74 can limit the second piston rod 72.

[0039] The first suction cup 2 is always adsorbed on the wall, and the suction force between the first suction cup 2 and the wall will slowly weaken with the gravity of the device. In order to prevent the device from falling, it is necessary to pressurize the suction force between the first suction cup 2 and the wall. Initially, the fourth spring 73 is in a compressed state, and the pull rod 43 is in a state of supporting the limit rod 74. First, when the pull rod 43 moves to the left, the pull rod 43 moves to the left to drive the first piston rod 41 to move to the left. At this time, a negative pressure state is generated between the first suction cup 2 and the wall, and the pull rod 43 and the limit rod 74 are separated. At the same time, since the first piston rod 41 is in a state of blocking the L hollow rod 71, the space between the right side of the second piston rod 72 and the L hollow rod 71 is also in a negative pressure state. Subsequently, when the first piston rod 41 moves to the left, so that the L hollow rod 71 is connected to the first suction cup 2, since there is a negative pressure state between the L hollow rod 71 and the first suction cup 2, the second piston rod 72 cannot move to the left. As the first suction cup 2 slowly leaks under the action of the gravity of the device, the second piston rod 72 slowly moves under the action of the fourth spring 73. The locking cam 720 is in a state of being pressed downwardly, and the locking cam 720 is in a state of being pressed downwardly, so that the locking cam 720 is in a state of being pressed downwardly, and the locking cam 720 is in a state of being pressed downwardly, and the locking cam 720 is in a state of being pressed downwardly, and the locking cam 720 is in a state of being pressed downwardly, and the The pull rod 43 moves to the right and pushes the limit rod 74 and the second piston rod 72 to move to the right and reset. At this time, the fourth spring 73 is compressed and the first piston rod 41 moves to the right and resets. After that, people can remove the device and repeat the above operation. Through the cooperation of the second piston rod 72 and the L hollow rod 71, the first suction cup 2 can be pressurized, thereby preventing the first suction cup 2 from falling off the wall under the action of gravity of the device, thereby preventing the device from separating from the wall and falling off.

[0040] As Figure 1 、 Figure 2 、 Figure 10 and Figure 11 shown, it further includes a protection mechanism 8 for protecting the road noise detector 3. The protection mechanism 8 includes a protective cover 81, a first elastic rope 82, a second elastic rope 83 and a second suction cup 84. The front and rear sides of the right part of the top wall of the support frame 1 are rotatably connected with a protective cover 81 respectively. The protective cover 81 can play a protective role for the road noise detector 3. A first elastic rope 82 is connected between the lower right side of the protective cover 81 and the left side of the upper T-shaped support rod 65. A second elastic rope 83 is connected between the right inner wall of the protective cover 81 and the road noise detector 3. The second elastic rope 83 can make the protective cover 81 rotate and reset. The upper and lower sides of the front wall of the front protective cover 81 are both connected with a second suction cup 84, and the upper and lower sides of the rear wall of the rear protective cover 81 are also both connected with a second suction cup 84. The second suction cup 84 can adsorb and fix the protective cover 81 on the wall surface.

[0041] When people need to protect the road noise detector 3, the protective cover 81 can achieve this function. Subsequently, if people need to detect the vehicle noise, first, when the T-shaped support rod 65 rotates to the right, the T-shaped support rod 65 rotates to the right and pulls the protective covers 81 to rotate away from each other and open through the first elastic rope 82. At this time, the first elastic rope 82 deforms. Subsequently, the second suction cup 84 will adsorb on the wall surface, and the second suction cup 84 can adsorb and fix the protective cover 81. The protective covers 81 rotating away from each other and opening makes the second elastic rope 83 deform. After that, the road noise detector 3 can be used to detect the vehicle noise. After the detection is completed, and when the T-shaped support rod 65 rotates to the left and resets, the first elastic rope 82 is released, so that the protective cover 81 is released. Then, the protective cover 81 rotates close to each other under the action of the second elastic rope 83, and the second suction cup 84 separates from the wall surface. The closing of the protective cover 81 can play a protective role for the road noise detector 3. Repeating the above operations, the protective cover 81 can play a protective role for the road noise detector 3, thereby preventing the road noise detector 3 from being damaged. At the same time, the first elastic rope 82 and the second elastic rope 83 cooperate with each other, so that the protective cover 81 can be automatically opened and closed, thereby improving the opening and closing efficiency of the protective cover 81.

[0042] As Figure 1 and Figure 12As shown in the figure, it further includes a reset mechanism 9 for expanding and clamping the clamping plate 52. The reset mechanism 9 includes a wedge-shaped limit block 91, a sliding frame 92 and a fifth spring 93. The left side of the support frame 1 is slidably connected with the sliding frame 92. Wedge-shaped limit blocks 91 are symmetrically fixed to the front and rear sides of the right part of the sliding frame 92 up and down. The wedge-shaped limit block 91 contacts the clamping plate 52. When the wedge-shaped limit block 91 moves to the right, it can expand the clamping plate 52. Fifth springs 93 are connected between the upper and lower parts of the sliding frame 92 and the left side of the support frame 1. The fifth springs 93 are wound around the sliding frame 92. The fifth springs 93 can make the sliding frame 92 move back to its original position.

[0043] When people need to reset the stuck pull rod 43, during detection, the clamping plate 52 clamps the pull rod 43. After the detection is completed, people press the sliding frame 92 to the right. At this time, the fifth spring 93 is compressed. When the sliding frame 92 moves to the right, it drives the wedge-shaped limit block 91 to move to the right. When the wedge-shaped limit block 91 moves to the right, it will expand the clamping plate 52. When the clamping plates 52 move away from each other, the pull rod 43 is released. After that, the pull rod 43 can be reset. After the pull rod 43 is reset, people release the sliding frame 92. The sliding frame 92 moves to the left and resets under the action of the fifth spring 93. When the sliding frame 92 moves to the left, it drives the wedge-shaped limit block 91 to move to the left and reset. Then the clamping plate 52 is released. Subsequently, the clamping plates 52 move closer to each other and reset. By repeating the above operations and moving the wedge-shaped limit block 91 to the right, the clamping plate 52 can be expanded, and thus the pull rod 43 can be moved and reset. In this way, it can improve the convenience for people and reduce the difficulty of the reset operation of the pull rod 43.

[0044] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present invention. Those skilled in the art will understand that the variant forms of the present invention will be included within the scope of the claims herein.
