[0035] The slider 17 and the sleeve 16 are fixedly connected, and each page 2 is hinged with a hinge rod 31. The end of the hinge rod 31 away from the page 2 is hinged to the sleeve 16.

[0036] The hook 23 includes a fixed rod 24 that is fixed to the sliding sleeve 16 at one end, and a bent portion 25 located at the end of the fixed rod 24 away from the sliding sleeve 16 for cooperating with the mating rod 22;

[0037] The bent portion 25 has a bevel on the side near the mounting plate to facilitate mating with the mating rod 22;

[0038] When the piston 18 is located at one end of the cavity near the mounting plate, the hook 23 and the mating rod 22 engage, and the two pieces 2 are coplanar.

[0039] The air pumping device includes an air pumping cylinder fixed to the cylinder body 3, a second piston slidably connected inside the air pumping cylinder, a second piston rod connected to the second piston, an air pumping shaft 26 rotatably connected to the cylinder body 3, an air pumping handle fixed to the air pumping shaft, a cam 27 fixed to the air pumping shaft, a third spring 28 for applying a force toward the cam 27 to the second piston rod, an air inlet located on the air pumping cylinder, a first one-way valve 29 located on the air inlet facing into the air pumping cylinder, an air outlet pipe 30 for connecting the air pumping cylinder and the cylinder body 3, and a second one-way valve located on the air outlet pipe 30 facing into the cylinder body 3.

[0041] The radius of the drive gear 14 is smaller than the radius of the driven gear 6.

[0042] The valve is a ball valve.

[0043] Principle of the Implementation Example:

[0044] Initially, see Figure 1 At this time, the valve is open, the pressure inside the cylinder 3 is high, the hook 23 and the mating rod 22 are engaged, the paddle 2 is coplanar, the friction plate 13 and the friction disc 11 are engaged, the first vent 8 is located above the groove 9, and the first vent 8 and the groove 9 are offset. At this time, when it is necessary to adjust the angle of the rotating rod, simply turn the first handle to drive the drive gear 14 to rotate, drive the driven gear 6 to rotate, and after the rotating rod rotates, it drives the mounting plate to rotate, thereby adjusting the angle of the battery plate 1 on the mounting plate.

[0045] When encountering snow outdoors, snow accumulates on the mounting plate. Under the influence of gravity, the lifting column 4 moves downward, increasing the pressure inside cylinder 3 and cylinder 12. This increases the pressure between the friction plate and friction disc 11, making the friction disc 11 more stable. The mounting plate will not rotate under the weight of the snow. As the weight of the snow continues to increase, the lifting column 4 continues to move downward. After the first air outlet and groove 9 mate, the gas inside cylinder 3 exits through the valve. At this time, the air pressure inside cylinder 12 decreases, and the friction plate and friction disc disengage. Under the action of the first spring 5, the rotating rod rotates to vertical. (See also...) Figure 8 Then the pressure inside the cavity decreases, and under the action of the second spring 20, the pressure of the mating rod on the bent part 25 increases, causing the bent part 25 to deform (see 7). As the pressure inside the cavity continues to decrease, the deformation of the bent part 25 continues to increase, and finally the hook 23 and the mating rod disengage, the sliding sleeve 16 moves towards the lifting column 4, and under the action of the hinge rod, the page 2 closes (see 7). Figure 9At this time, the snow slides off page 2 under the action of gravity, thereby reducing the pressure on page 2 and protecting the battery panel. After the snow stops, close the valve and turn the air pump handle. Under the action of the cam, the second piston moves up and down, the pressure in the cylinder 3 increases, the lifting column 4 moves upward, the pressure in the cavity increases, the piston 18 moves to the end of the cavity, and under the action of the inclined plane, the hook 23 and the mating rod re-engage, the mounting plate unfolds again, the pressure in the cylinder 12 increases, the friction plate and the friction disc re-engage, and then the angle of the rotating rod can be adjusted by turning the first handle.
