By arranging the crankshaft connecting rod mechanism, the sliding rail sliding block mechanism or the gear rack mechanism between the substrate 100 and the guard plate 400, the driving mechanism 200 drives the crankshaft connecting rod mechanism, the sliding rail sliding block mechanism or the gear rack mechanism to drive the guard plate 400 to move between the first position a and the second position B, so that the guard plate 400 can shield or expose the detection device. For example, the driving mechanism 200 may be a motor to adapt to the connecting rod assembly, and the connecting rod assembly includes one or more connecting rods respectively connected (e.g., hinged) to the power output end of the motor and the guard, and the power output end of the motor drives the connecting rods to rotate, so as to drive the guard 400 to move, so as to move the guard 400 between the first position a and the second position B. In order to adapt to the crankshaft connecting rod mechanism, the driving mechanism 200 may be an engine, the crankshaft connecting rod mechanism may convert the reciprocating motion of a piston in the engine into a rotating motion of a crankshaft, the crankshaft is connected (e.g., hinged) to the guard plate 400 through a connecting rod, and the crankshaft drives the connecting rod to rotate when rotating, and then can drive the guard plate 400 to move, so as to enable the guard plate 400 to move between the first position a and the second position B. In order to adapt to the slide rail and slide block mechanism, the driving mechanism 200 may be an air cylinder, a slide rail is respectively disposed on one of the substrate 100 and the guard plate 400, a slide block is disposed on the other one of the substrate 100 and the guard plate 400, the slide block is slidably connected to the slide rail, the air cylinder is drivingly connected to the slide block, and the air cylinder drives the slide block to slide on the slide rail, so that the guard plate 400 moves between the first position a and the second position B.

In this embodiment, the transmission mechanism 300 includes a connecting rod assembly, and the connecting rod assembly is respectively rotatably connected to the power output end of the driving mechanism 200 and the guard plate 400. Due to the design, the driving mechanism 200 drives the connecting rod assembly to rotate, and then the guard plate 400 can be driven to move, so that the guard plate 400 can move between the first position A and the second position B. Because link assembly and backplate 400 are for rotating the connection, rather than fixed connection, when link assembly drove backplate 400 and moves, backplate 400 formed horizontal migration, switches between first position A and second position B, and then realizes that backplate 400 shelters from or exposes detection device.

Further, in some embodiments, the link assembly includes a first link 310, and the first link 310 is rotatably connected to the power output end of the driving mechanism 200, the substrate 100, and the shield 400, respectively. In this embodiment, the first connecting rod 310 may be rotatably connected to the substrate 100 by a rotating connecting member 330, and the driving mechanism 200 drives the first connecting rod 310 to rotate along a circumferential direction of the rotating connecting member 330, so as to drive the guard plate 400 to move between the first position a and the second position B.

It should be noted that, referring to fig. 1 to 2, when the connecting rod assembly includes the first connecting rod 310 and the second connecting rod 320, the driving mechanism 200 may be disposed only on the first connecting rod 310, the driving mechanism 200 drives the first connecting rod 310 to rotate, so as to drive the protecting plate 400 to move, the second connecting rod 320 rotates along with the movement of the protecting plate 400, and the protecting plate 400 can move smoothly under the combined traction action of the first connecting rod 310 and the second connecting rod 320. Similarly, the driving mechanism 200 may be disposed on both the first connecting rod 310 and the second connecting rod 320, and the driving mechanism 200 drives the first connecting rod 310 and the second connecting rod 320 to rotate together, so as to drive the guard plate 400 to move smoothly, thereby moving the guard plate 400 between the first position a and the second position B. Thus, when the hovercar runs on land, the guard plate 400 is located at the first position A, the guard plate 400 can protect the detection device at the bottom of the hovercar body, and objects such as stones are prevented from splashing to damage the detection device; when the hovercar takes off or lands, the guard plate 400 is located at the second position B to ensure that the detection device at the bottom of the hovercar body can normally detect the obstacle, so that the take-off or landing safety performance of the hovercar is improved. Therefore, the protection requirement and the detection requirement of the detection device at the bottom of the aerocar body can be met, the process that the protection device needs to be disassembled and assembled by using a special tool in the related technology is omitted, and manual operation is reduced.
