The structure and connection manner of the third hinge 1311 and the third support 122 can refer to the structure and connection manner of the first hinge 111 and the first support 121, and are not described herein again.
In some embodiments, the first hinge shaft 140, the second hinge shaft 141, and the third hinge shaft 142 are axially identical. Therefore, the scissor jack 130 can more smoothly drive the boarding plate 110 to rotate relative to the connecting plate 120, and the problem that the scissor jack 130, the connecting plate 120 and the boarding plate 110 are stuck is not easy to occur.
In some embodiments, the number of the scissor jacks 130 is plural, and the plurality of scissor jacks 130 are sequentially distributed along the axial direction of the first hinge shaft 140. Therefore, the supporting force of the scissor jack 130 acting on the boarding plate 110 is distributed more uniformly, and when the forklift moves onto the boarding plate 110, the problem that the side edge of the boarding plate 110 is inclined due to nonuniform stress is solved.
Specifically, as shown in fig. 1 and 2, the number of the scissor jacks 130 is two, and the two scissor jacks 130 are distributed on both sides of the boarding plate 110 in the axial direction of the first hinge shaft 140 to support the boarding plate 110 in both axial sides of the first hinge shaft 140. The number of the connecting plates 120 is also two, the third ends of the two connecting plates 120 are respectively hinged to the first ends of the boarding plates 110, and the second ends of the two connecting plates 120 are respectively hinged to the bottoms of the two scissor jacks 130. Of course, the connecting plate 120 may be a unitary structure, and two scissor jacks 130 may be supported on the same connecting plate 120.
In some embodiments, as shown in fig. 1 and 2, the scissor jack 130 includes a base 131, two first support rods 132 hinged to the base 131, a third hinge 1311 fixedly installed on a lower surface of the base 131, two ends of the first support rods 132 away from the base 131 respectively hinged to the second support rods 133, one ends of the second support rods 133 away from the first support rods 132 respectively hinged to a top seat 134, and a second support portion 1341 fixedly installed on a top surface of the top seat 134.
A screw rod seat 135 is hinged to one end, far away from the base 131, of a first supporting rod 132 of the scissor jack 130, and a threaded hole is formed in the screw rod seat 135; the other end of the first supporting rod 132 of the scissor jack 130, which is far away from the base 131, is hinged with a mounting seat 137, a mounting hole (not shown in the figure) for mounting the lead screw 136 is formed in the mounting seat 137, the lead screw 136 penetrates through a threaded hole of the lead screw seat 135 and is in threaded connection with the lead screw seat 135, the lead screw 136 penetrates through the mounting hole of the mounting seat 137 and is rotatably connected with the mounting seat 137, and the mounting seat 137 can limit the axial movement of the lead screw 136 along the lead screw 136.
The mounting base 137 is further provided with a motor 138, and a rotating shaft of the motor 138 is connected with the lead screw 136 through a gear set to drive the lead screw 136 to rotate, so that the lead screw base 135 moves along the axial direction of the lead screw 136, and further drives the two first supporting rods 132 and the two second supporting rods 133 to rotate, so as to realize the ascending or descending of the scissor jack 130.
In some embodiments, the axial direction of the lead screw 136 may be aligned with the axial direction of the first hinge shaft 140, and thus, when the scissor jack 130 is lowered to a lower height, the first and second support rods 132 and 133 of the scissor jack 130 do not protrude toward the first end of the boarding plate 110 but interfere with the lowered boarding plate 110, and thus, an angle formed by the boarding plate 110 and the connection plate 120 can be further made smaller, that is, a height of the second end of the boarding plate 110 can be made lower.
In some embodiments, the motors 138 of the scissor jacks 130 may be connected to the same controller to achieve synchronous control of the scissor jacks 130, so that the scissor jacks 130 can be lifted synchronously, and the problem that the boarding plate 110 is tilted to the side due to too fast or too slow lifting of one scissor jack 130 can be avoided.
Specifically, as shown in fig. 3, a control module 150 is disposed at the bottom of the boarding plate 110, and the motors 138 of the scissor jacks 130 are electrically connected to the control module 150, respectively, so as to implement synchronous control of the motors 138.

In some embodiments, the upper surface of the connection plate 120 is convexly provided with a hook structure 123. Therefore, the forklift or other conveying devices can convey the boarding device 100 through the hook, and the conveying of the boarding device 100 is more convenient.
Specifically, as shown in fig. 3, the number of the connecting plates 120 is two, two hook structures 123 are provided on each connecting plate 120, and a hanging hole 1231 for inserting a front fork of a forklift is provided on each hook structure 123. The hook structures 123 on the two connecting plates 120 are arranged opposite to each other in the arrangement direction of the two connecting plates 120, so that the hook structures 123 on the two connecting plates 120 can be hung on the front fork of the forklift simultaneously.
In some embodiments, as shown in fig. 4, a first rib 113 is protruded on the lower surface of the boarding plate 110, and the first rib 113 extends along a direction from the first end to the second end of the boarding plate 110, so as to improve the strength of the boarding plate 110 and prevent the boarding plate 110 from being deformed downward by the gravity of a transport vehicle such as a forklift.
The number of the first reinforcing ribs 113 is plural, and the plural first reinforcing ribs 113 are sequentially distributed along the axial direction of the first hinge shaft 140, so as to further improve the strength of the boarding plate 110.
In some embodiments, as shown in fig. 1 and 4, the boarding device 100 further includes a tongue plate 160, and one side of the tongue plate 160 is hinged to the side of the first end of the boarding plate 110. It can be understood that, because the height of the first end of the boarding plate 110 changes during the rotation of the boarding plate 110 in the up-down direction, when the boarding plate 110 rotates downward to a smaller angle, the height of the first end of the boarding plate 110 is higher, at this time, the tongue plate 160 hinged to the side edge of the first end of the boarding plate 110 rotates downward to a position where the first end abuts against the ground under the action of its own gravity, so that a transition effect is achieved between the first end of the boarding plate 110 and the ground, and the forklift can smoothly move from the ground to the boarding plate 110.
Specifically, the boarding device 100 includes a first hinge 161, and the first hinge 161 includes two mutually hinged blades, wherein one blade of the first hinge 161 is fixedly connected to the lower surface of the first end of the boarding plate 110, and the other blade is fixedly connected to the lower surface of the tongue plate 160, so that one side edge of the tongue plate 160 is hinged to the side edge of the first end of the boarding plate 110.
The number of the first hinges 161 is plural, and the plural first hinges 161 are sequentially distributed along the extending direction of the side edge of the first end of the boarding plate 110, so as to improve the connection strength between the tongue plate 160 and the boarding plate 110.
In some embodiments, the boarding device 100 includes a strap 170, and one side of the strap 170 is hinged to a side of the second end of the boarding plate 110. It can be understood that, after the tail of the truck carriage is parked close to the platform, a certain gap may exist between the truck carriage and the platform, at this time, the access board 170 rotates downwards under the action of self gravity, so that the access board 170 extends into the truck carriage, and the free end of the access board 170 abuts against the bottom surface of the truck carriage, thereby playing a transition role between the boarding board 110 and the truck carriage, and enabling the forklift to smoothly move from the boarding board 110 to the truck carriage.
Specifically, the boarding device 100 includes a second hinge 171, and the second hinge 171 includes two mutually hinged blades, wherein one blade of the second hinge 171 is fixedly connected to the lower surface of the second end of the boarding plate 110, and the other blade is fixedly connected to the lower surface of the access plate 170, so that one side edge of the access plate 170 is hinged to the side edge of the second end of the boarding plate 110.
The number of the second hinges 171 is plural, and the plural second hinges 171 are sequentially distributed along the extending direction of the side edge of the second end of the boarding plate 110, so as to improve the connection strength between the access plate 170 and the boarding plate 110.
In some embodiments, as shown in fig. 1, a second reinforcing rib 172 is further disposed on the lower surface of the access panel 170, and the second reinforcing rib 172 extends in a direction away from the boarding plate 110 along the access panel 170 to improve the strength of the access panel 170 and prevent the access panel 170 from bending and deforming downward under the action of the gravity of the forklift.
The number of the second reinforcing ribs 172 is plural, and the plural second reinforcing ribs 172 are sequentially distributed along the axial direction of the first hinge shaft 140, so as to further improve the strength of the strap 170.
