When the car carrying plate is lifted by the lifting mechanism, the lifting or descending of the car carrying plate is stopped when the car carrying plate moves to a preset position, otherwise, safety accidents are easy to cause. In order to solve the technical problems, the technical scheme adopted by the application is that a limit switch coupled with a driving device is in a first gesture before contacting with a limiting block; and after the vehicle carrying plate contacts with the limiting block, the vehicle carrying plate rotates to a second gesture under the pushing of the limiting block so as to control the driving device to stop driving the transmission assembly to move, thereby accurately controlling the vehicle carrying plate to stop ascending or descending when moving to a preset position. The following detailed description refers to the accompanying drawings.
Referring to fig. 1, fig. 1 is a schematic front view of an embodiment of a lifting mechanism provided in the present application. As shown in fig. 1, the lifting mechanism comprises a lifting frame 2, a transmission assembly 3 (a part shown by a dotted line frame in the figure) fixed on a cross beam 21 of the lifting frame 2, a driving device 23, a limit switch 4 fixed on the lifting frame 2, and a limit block 5 fixed on the transmission assembly 3, wherein the limit switch 4 is coupled with the driving device 23. When the driving device 23 drives the transmission assembly 3 to move so as to drive the vehicle carrying board 1 to ascend or descend, the limiting block 5 follows the transmission assembly 3 to move along a first direction or along a second direction opposite to the first direction, and two directions shown by arrows 25 and 24 in the figure respectively represent the first direction and the second direction; before the limit switch 4 is in contact with the limit block 5, the limit switch takes a first posture; after contacting the limiting block 5, the driving device 23 is controlled to stop driving the transmission assembly 3 to move by being pushed by the limiting block 5 to rotate to a second posture. In fig. 1, limit switches 4 are fixedly arranged at O1 and O2 of the beam 21, respectively, the first direction is a direction from the O2 point to the O1 point, and the second direction is a direction from the O1 point to the O2 point.
The limit switch 4 comprises a limit main body 41, a first force arm 42 and a second force arm 43, wherein the limit main body 41 is fixed on the beam 21 of the lifting frame 2, and the upright post 22 is used for supporting the whole lifting mechanism. The first force arm 42 is hinged to the limiting main body 41, and the second force arm 43 is connected with the limiting main body 41; the first force arm 42 is in a first posture of being out of contact with the second force arm 43 when not in contact with the limiting block 5; the second posture is achieved when the stopper 5 is pushed to contact with the second arm 43.
The vehicle carrying plate 1 is connected with the transmission assembly 3, the driving device 23 drives the transmission assembly 3 to move so as to drive the vehicle carrying plate 1 to lift, the first force arm 42 is pushed by the limit block 5 when the vehicle carrying plate 1 is located at a preset position and rotates to be in contact with the second force arm 43 to form a second gesture, the limit switch 4 is conducted at the moment, and a control circuit in the limit switch 4 is triggered to send an instruction to the driving device 23 to control the driving device 23 to stop running. When the vehicle carrying plate 1 is at the non-preset position, the first force arm 42 and the second force arm 43 are in a first non-contact posture, and at the moment, the driving device 23 works normally to drive the vehicle carrying plate 1 to ascend or descend.
Wherein the driving means 23 comprises a motor, a cylinder, a hydraulic machine, etc. for providing the driving force.
The preset position is the position where the height of the vehicle carrying plate 1 is the same as the height of the three-dimensional garage position where the lifting mechanism is matched with the parking. For example, when the stereo garage has two layers, the vehicle carrying board 1 has two preset positions, the first position is the same as the first layer of garage position in height, and also can be the ground, and the second preset position is the same as the second layer of garage position in height. In an alternative embodiment, for convenience of control, the highest position where the vehicle carrying plate 1 can move may be corresponding to the height of the highest layer of the stereo garage, and the lowest position where it can move may be corresponding to the height of the first layer of the stereo garage, such as the ground. For example, when the stereo garage is two-layer, the highest position where the vehicle carrying plate can ascend is the position corresponding to the height of the second-layer garage, and the lowest position where the vehicle carrying plate descends is the position corresponding to the ground.
In this embodiment, the limiting block 5 is fixed on the transmission assembly 3, moves along with the transmission assembly 3 along the first direction or the second direction, and pushes the first arm 42 of the limit switch 4 to rotate to be in contact with the second arm 43 to form a second gesture when reaching a predetermined position, and at this time, the control circuit in the limit switch 4 sends an instruction to the driving device 23 to control the driving device 23 to stop running, so as to avoid up-and-down shaking of the vehicle carrying plate, and thus improve the safety of parking/taking vehicles.

When the vehicle carrying plate 1 moves up and down under the traction of the transmission assembly 3, the limiting block 5 moves along the transmission assembly 3 along the first direction or the second direction between the two limit switches 4. When the transmission assembly 3 drives the vehicle carrying plate 1 to move to a preset position, the limiting block 5 contacts with one end of the first force arm 42 to push the first force arm 42 to rotate around the pivot 44 until the first force arm 42 contacts with the second force arm 43 to form a second gesture, the limit switch 4 is conducted, the driving device 23 stops running, and the vehicle carrying plate 1 stops lifting movement.

Preferably, as shown in fig. 2, the limiting block 5 includes a base 51 and a bevel body 52 fixed on the base 51, the base 51 is fixed on the transmission device 3, and when the bevel body 52 pushes the roller or drum 45 of the first force arm 42 to slide along the bevel body 52, the first force arm 42 can be pushed to rotate in a direction opposite to the rolling direction of the roller or drum 45, such as in a counterclockwise direction in fig. 2.
