DETAILED DESCRIPTION

[0049] The following will be combined with the drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the described embodiments are part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments in the present disclosure, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present disclosure.

[0050] The specific embodiments of the present disclosure are described in detail below with reference to the accompanying drawings.

[0051] See also Figure 1 and Figure 2As shown, the present application provides a cylinder guide mechanism 16, including: a cylinder seat 162, a connecting rod 163 and a first cylinder 161 (telescopic cylinder). The cylinder seat 162 has a first connecting hole and a second connecting hole. The connecting rod 163 includes a rod body, a first transmission bar 167 and a second transmission bar 168. The rod body can slide through the second connecting hole. The two ends of the rod body are respectively provided with a first steering component 164 and a second steering component 165. The first transmission bar 167 bypasses the first steering component 164, and one end is fixedly connected to the cylinder seat 162, and the other end is provided with a lock 169. The second transmission bar 168 bypasses the second steering component, and one end is fixedly connected to the cylinder seat 162, and the other end is provided with a lock 169. The first cylinder 161 is arranged through the first connecting hole, and the telescopic end of the first cylinder is connected to the first steering component 164. The telescopic movement of the first oil cylinder can drive the two lock buckles 169 to move in a long distance in a bidirectional telescopic manner, and when the first oil cylinder is telescoped at a speed v, it can drive the lock buckles 169 to move at a speed of 2v, thereby significantly improving the working efficiency.

[0052] The lock buckle 169 is connected to the telescopic frame of the lifting device 1, and the lock buckle 169 can adjust the length and tension of the transmission bar (which can be a steel wire or a rope). By adopting the above-mentioned technical solution of the embodiment of the present application, the reciprocating movement distance of the telescopic frame is significantly improved, which can meet the two-way (left and right) mobile lifting requirements of the lifting device 1. When a plurality of the cylinder guide mechanisms 16 are arranged on the lifting device 1, long-distance movement of the multi-stage telescopic frame on the lifting device 1 can be achieved, and the horizontal arrangement of the cylinder guide mechanism 16 can realize the movement of the multi-stage telescopic frame on both sides along the width direction of the chassis of the battery-changing vehicle.

[0053] In a possible implementation, the oil cylinder guide mechanism 16 includes two connecting rods 163, which are respectively arranged on both sides of the first oil cylinder 161. The telescopic end of the first oil cylinder is connected to a stabilizing push rod 166, which is respectively connected to the first steering components 164 of the two connecting rods 163. The stability of the transmission is improved by providing two connecting rods 163.

[0054] Optionally, the first steering component 164 and the second steering component 165 both include pulleys connected to the ends of the connecting rod 163. In this way, during the reciprocating motion of the connecting rod 163, the pulleys can rotate, thereby reducing the motion resistance of the transmission bar.

[0055] See also Figure 2As shown, the middle state diagram is the original position of the oil cylinder guide mechanism 16, the top state diagram is a schematic diagram of when the first oil cylinder 161 extends to the right by a length of L, and the telescopic frame moves to the right by 2L. The bottom state diagram is a schematic diagram of when the first oil cylinder retracts to the left by a length of L from the state shown in the middle state diagram, and the telescopic frame moves to the left by 2L.
