[0002] The car dashboard bracket is an important part of the car dashboard system. It supports and fixes the dashboards in the car body. There are a large number of mounting holes on the dashboard bracket to fix the components with screws.

Figure 4 As shown, the movable sleeve 3 is respectively fixedly connected to the outer surfaces of both ends of the lower detection plate 6, an upper detection plate 7 is provided parallel to the upper end of the lower detection plate 6, and a driving device for driving the upper detection plate 7 to move is provided between the upper detection plate 7 and the base 1, wherein the lower surface of the upper detection plate 7 is provided with a protrusion for detecting the bracket, and the lower detection plate 6 is provided with a clamp for fixing the bracket.

[0030] In this embodiment, a guide device is provided between the lower detection plate 6 and the base 1, and the guide device includes a sleeve 8, and the number of the sleeves 8 is two. Figure 3 As shown, the two sleeves 8 are fixedly connected to one side of the lower surface of the lower detection plate 6, as shown in FIG. Figure 1 As shown, the two sleeves 8 are symmetrically arranged, and the inner surfaces of the two sleeves 8 are rotatably provided with the same rotating shaft 9, and the two ends of the rotating shaft 9 pass through the sleeves 8 respectively.

When one side of the lower detection plate 6 is subjected to pressure, the rotating shaft 9 on the same side drives the movable rod 11 to slide inside the guide rail 10 through the connecting rod 12, and the movable rod 11 drives the sleeve 8 to move through the connecting rod 12 on the other side, so that the lower detection plate 6 remains in a horizontal state, preventing the lower detection plate 6 from being offset and damaged by external force.

[0031] In this embodiment, if Figure 4 As shown, a through slot 13 is penetrated through the end surface of the lower detection plate 6, and the through slot 13 is rectangular. A strip groove 14 is provided at one end of the end surface of the lower detection plate 6 corresponding to the through slot 13. A plurality of rotating rods 15 are rotatably provided on the inner surfaces of both ends of the through slot 13. The rotating rods 15 are respectively penetrated through the side walls of the through slot 13 at one end corresponding to the end close to the strip groove 14 and are fixedly connected with a first gear 16.

A motor 19 is fixedly connected to the surface of the lower detection plate 6. The output shaft of the motor 19 passes through the side wall of the strip groove 14 and is fixedly connected to one of the first gears 16. When the motor 19 drives a first gear 16 to rotate, the first gear 16 drives the rotating rod 15 to rotate through gear matching, and the fixture 18 thereon also rotates at the same time. By installing different fixtures and controlling the corresponding fixture 18 to be located at the upper end, different matching modes can be formed, so as to adapt to automobile dashboard brackets of different shapes and increase the applicability of the device.

[0032] In this embodiment, if Figure 1As shown, the driving device includes a screw rod 20, which is rotatably connected to the upper surface of the base 1, and the screw rod 20 passes through the end surface of the upper detection plate 7, and the screw rod 20 is screwed to the upper detection plate 7. When the screw rod 20 rotates under the action of an external motor, the movement of the upper detection plate 7 can be controlled.

[0033] In this embodiment, the lower surface of the base 1 is fixedly connected to a shell 21, the lower ends of the screw rods 20 pass through the end surfaces of the base 1 and are fixedly connected to rollers 22, and the rollers 22 are respectively located inside the shell 21, and a belt 23 is sleeved between the two rollers 22, thereby driving the screw rod 20 on one side to rotate, and the screw rod 20 on the other side can be rotated at the same time through the transmission of the belt 23, ensuring that the upper detection plate 7 can maintain horizontal movement.

[0034] In this embodiment, the upper ends of the screw rods 20 are respectively fixedly connected with annular limit plates 24 to prevent the upper detection plate 7 from being separated from the screw rods 20 .

[0035] The working principle of a dashboard bracket detection fixture of this embodiment is as follows:

[0036] When the detection fixture is in use, the instrument panel bracket is fixed on the lower detection plate 6 by the fixture 18. After rotating the screw rod 20 on one side, the screw rod 20 on the other side is driven to rotate simultaneously through the transmission of the belt 23, so that the upper detection plate 7 is lowered, and the protrusion on the upper detection plate 7 passes through the instrument panel bracket, which means that the instrument panel bracket is qualified. If the protrusion contacts the instrument panel bracket, the movable sleeve 3 compresses the spring 5 to form a buffer. At the same time, the rotating shaft 9 and the movable rod 11 make the lower detection plate 6 always maintain a horizontal state to prevent deviation. The motor 19 is started to drive the first gear 16 to rotate. The cooperation between the first gear 16 and the second gear 17 makes the rotating rod 15 rotate simultaneously, so that the fixtures 18 on different sides are rotated to the upper end, and then used to fix different instrument panel brackets.
