[0028] The following is combined with Figure 1-4 The present invention is described in further detail.

[0029] Reference Figure 1The present invention discloses a quick-release mechanism for a vehicle-mounted upper-mounted device, comprising a vehicle-mounted mounting plate 1 and a carrying plate 2. The vehicle-mounted mounting plate 1 is fixedly connected to a threaded hole provided on a vehicle body through a self-contained locking bolt to ensure that the vehicle-mounted mounting plate 1 is stably fixed at a position on the vehicle body where operation and use are required; the vehicle-mounted device is connected to the carrying plate 2, and then the carrying plate 2 is carried on the vehicle body; a moving wheel 3 is installed at the bottom of the carrying plate 2 to facilitate the movement of the vehicle-mounted device on the carrying plate 2, and also comprises a positioning ring 4, a lifting mechanism 5, a limiting groove 6 and a clamping mechanism 9 installed on the carrying plate 2, and a limiting mechanism 7 and a hydraulic cylinder 8 installed on the vehicle-mounted mounting plate 1.

[0030] The lifting mechanism 5 drives the positioning ring 4 to rise and fall outside the moving wheel 3. The positioning ring 4 is lifted and lowered by controlling the lifting mechanism 5. When the positioning ring 4 is raised, the carrying board 2 is easy to move through the moving wheel 3. When the positioning ring 4 is lowered, the position of the carrying board 2 can be fixed, which is convenient for loading the vehicle-mounted equipment. The clamping mechanism 9 is fixed to the top outer side of the carrying board 2. The clamping mechanism 9 can realize rapid clamping and disassembly of the vehicle-mounted equipment. The limiting groove 6 is opened on the side wall of the positioning ring 4. Both sides of the top of the vehicle-mounted mounting plate 1 are slidably connected to the limiting mechanism 7. The hydraulic cylinder 8 controls the limiting mechanism 7 to limit the limiting groove 6 on the positioning ring 4. When the vehicle-mounted equipment on the carrying board 2 is loaded onto the vehicle body, the hydraulic cylinder 8 is driven to drive the limiting mechanism 7 to act, and then the limiting mechanism 7 cooperates with the limiting groove 6 to fix the vehicle-mounted equipment on the carrying board 2 through the positioning ring 4.

[0031] Reference Figure 2 The lifting mechanism 5 includes a driving motor 505 installed at the bottom of the carrying board 2, and the output end of the driving motor 505 is connected to a screw rod 503, and the outer part of the screw rod 503 is screwed with a main board 501, and the side wall of the main board 501 is connected to the positioning ring 4 through a support plate 502. A plurality of limiting rods 504 penetrating the support plate 502 are provided at the bottom of the carrying board 2. By starting the driving motor 505, under the action of the screw rod 503 and the limiting rod 504, the positioning ring 4 is driven to be lifted and lowered, thereby fixing and moving the carrying board 2.

[0032] The clamping mechanism 9 includes two groups of fixing plates 901 fixed on the top of the vehicle-mounted mounting plate 1, and clamping plates 902 are provided on the opposite sides of the two groups of fixing plates 901. The clamping plates 902 on both sides are in an inverted eight shape. Springs 903 of different lengths are connected between the clamping plates 902 and the fixing plates 901. A pull block 904 runs through the middle of the fixing plate 901. The pull block 904 extends to one end of the clamping plate 902 and is hinged to the clamping plate 902 through a hinge seat 905. Due to the design of the clamping mechanism 9, the vehicle-mounted equipment can be quickly placed between the two groups of clamping plates 902, and then under the action of the spring 903, the vehicle-mounted equipment is fixed. When the vehicle-mounted equipment needs to be disassembled, it only needs to pull the pull block 904 outward to achieve quick disassembly of the vehicle-mounted equipment.

[0033] Reference Figure 3 A slideway 101 for sliding the moving wheel 3 is provided on the upper surface of the vehicle-mounted mounting plate 1, so that the vehicle-mounted equipment on the carrying plate 2 can slide on the vehicle-mounted mounting plate 1, saving effort. Positioning grooves 102 for positioning the positioning ring 4 are provided at both ends of the slideway 101. When the carrying plate 2 moves to one end through the slideway 101, the positioning ring 4 is controlled to descend into the positioning groove 102, so that the positioning of the carrying plate 2 can be achieved.

[0034] The limiting mechanism 7 includes two groups of limiting plates 701. The outermost side of the upper surface of the vehicle-mounted mounting plate 1 is provided with a slide groove 103. The limiting plate 701 of the limiting mechanism 7 is slidably connected to the slide groove 103 to ensure the stability of the limiting plate 701 during movement, thereby ensuring that the limiting column 702 on the limiting plate 701 can accurately position the positioning ring 4. Limiting columns 702 are provided on the opposite side walls of the two groups of limiting plates 701. One end of the limiting plate 701 is provided with a driven wedge block 703. An active trapezoidal block 704 is fitted between the two groups of driven wedge blocks 703. The telescopic end of the hydraulic cylinder 8 is connected to the side wall of the active trapezoidal block 704. When the hydraulic cylinder 8 is controlled to move, the active trapezoidal block 704 is driven to move, thereby driving the driven wedge blocks 703 on both sides to drive the limiting plates 701 to move closer to or away from each other, so as to realize the quick release of the carrying plate 2.

[0035] Reference Figure 4 A guide groove 706 is provided on the inclined surface 705 of the driven wedge block 703, and a guide protrusion 707 adapted to the guide groove 706 is provided on the side of the active trapezoidal block 704 that is in contact with the inclined surface 705. Under the action of the guide groove 706 and the guide protrusion 707, the driven wedge block 703 can move away from or closer to each other as the active trapezoidal block 704 moves.

[0036] The working principle of the quick release mechanism of a vehicle-mounted upper device of the present invention is as follows:

[0037] By arranging the vehicle-mounted mounting plate 1 at different positions on the vehicle body, different vehicle-mounted equipment is placed on the carrying plate 2, and the vehicle-mounted equipment is quickly fixed by the clamping mechanism 9. Then, after the carrying plate 2 is slid to a certain position on the vehicle-mounted mounting plate 1, the positioning ring 4 is first controlled by the lifting mechanism 5 for positioning, and then the hydraulic cylinder 8 is controlled to drive the limiting mechanism 7 to position the limiting groove 6 on the positioning ring 4. This not only ensures the stability of the vehicle-mounted equipment on the carrying plate 2, but also allows the carrying plate 2 to be stably installed on the vehicle-mounted mounting plate 1, the carrying plate 2 can be quickly positioned on the vehicle body, and the vehicle-mounted equipment on the carrying plate 2 can be quickly interchanged, thereby improving the switching efficiency and interchangeability of the vehicle-mounted equipment.

[0038] The above are all preferred embodiments of the present invention, and are not intended to limit the protection scope of the present invention. Therefore, any equivalent changes made based on the structure, shape, and principle of the present invention should be included in the protection scope of the present invention.
