[0020] In order to make the technical means, creative features, purpose and efficacy of the utility model easy to understand, the utility model is further described below in conjunction with specific embodiments, but the following embodiments are only preferred embodiments of the utility model, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the scope of protection of the utility model. The experimental methods in the following embodiments are conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments are all commercially available unless otherwise specified. Example

[0021] like Figure 1-Figure 4 As shown, a transmission mechanism of a shuttle car includes a transverse car 1 and a tray 2. A support plate 3 is fixedly connected to the middle of the transverse car 1. The bottom end of the tray 2 is on the top surface of the support plate 3. An inner groove is provided on the inner side of the transverse car 1. A clamping mechanism is provided on the inner side of the inner groove. The clamping mechanism includes: a sliding bracket 9, which is used to fix the tray 2 on the surface of the support plate 3 when the transverse car 1 moves. A groove is provided on one side of the sliding bracket 9. A transmission mechanism is provided on the inner side of the groove. The transmission mechanism includes: a conveyor belt 11. One side of the conveyor belt 11 is in contact with the side surface of the tray 2 and is used to push the tray 2 away from the support plate 3. surface; a push block 8 is arranged on the other side of the sliding bracket 9, and an electric push rod 7 is fixedly connected to the bottom end of the push block 8, and the bottom end of the electric push rod 7 is fixedly connected to the inner wall of the inner groove; a first spring 13 is fixedly connected to the connection between one side of the sliding bracket 9 and the inner wall of the inner groove; a rotating shaft 12 is fixedly connected to the connection between the conveyor belt 11 and the inner wall of the groove, and a servo motor 10 is fixedly connected to the top of the rotating shaft 12, and the top of the servo motor 10 is fixedly connected to the inner wall of the groove; a longitudinal car 4 is arranged at the bottom end of the support plate 3, and a lifting plate 5 is arranged at the top end of the longitudinal car 4, and a slide groove 6 is opened at the bottom end of the tray 2, and the top end of the lifting plate 5 is located inside the slide groove 6;

[0022] The existing shuttle vehicles do not move continuously when transferring goods. Two vehicles need to stop at the same time. After the goods are transferred to another vehicle, the other vehicle starts to transport them to the destination. The waiting time is long and the work efficiency is greatly reduced. By setting up a transmission mechanism, such as Figure 1 As shown, when the longitudinal vehicle 4 approaches the transverse vehicle 1, the servo motor 10 is started, the servo motor 10 drives the rotating shaft 12 to rotate, the rotating shaft 12 drives the conveyor belt 11 to rotate, and the conveyor belt 11 pushes the pallet 2 to slide on the surface of the support plate 3. The travel speed of the longitudinal vehicle 4 is greater than the sliding speed of the pallet 2. When the head of the longitudinal vehicle 4 arrives at the tail of the pallet 2, the lifting plate 5 rises a short distance, and the top of the lifting plate 5 enters the inner side of the slide groove 6, as shown in FIG. Figure 4 As shown, the longitudinal vehicle 4 continues to move and the front end of the lifting plate 5 touches the inner wall of the chute 6. The longitudinal vehicle 4 is blocked by the inner wall of the chute 6 and the speed decreases, and it moves along with the pallet 2. At this time, the longitudinal vehicle 4 is directly below the pallet 2, and the lifting plate 5 starts to rise for the second time, supporting the inner wall at the top of the chute 6, giving the pallet 2 an upward thrust, as shown in FIG. Figure 1 and Figure 2 As shown, while the lifting plate 5 rises for the second time, the electric push rod 7 is started, and the electric push rod 7 pulls the push block 8 to move downward on the inner side of the inner groove of the transverse car 1. The sliding bracket 9 is not blocked by the push block 8. The first spring 13 in the contracted state pushes the sliding bracket 9 to move in the direction of the push block 8 on the inner side of the inner groove. At this time, the conveyor belt 11 gradually breaks away from the contact with the pallet 2, and the pallet 2 falls completely on the lifting plate 5. The longitudinal car 4 speeds up and takes the pallet 2 away from the inside of the transverse car 1 and drives to the destination; when the longitudinal car 4 transfers the goods to the transverse car 1, the longitudinal car 4 brings the pallet 2 close to the side of the transverse car 1, and the lifting plate 5 gradually decreases in height, and the bottom end of the pallet 2 gradually slides close to the surface of the support plate 3. At the same time, the electric push rod 7 is started, and the electric push rod 7 pushes the push block 8. The push block 8 pushes the sliding bracket 9 to move inside the inner groove of the transverse car 1, and the conveyor belt 11 gradually comes out from the inside of the inner groove and contacts the side of the pallet 2. The servo motor 10 is also started at the same time, driving the conveyor belt 11 to rotate and start to reduce the sliding speed of the pallet 2. When the longitudinal car 4 arrives just below the support plate 3, the lifting plate 5 is completely retracted into the inside of the longitudinal car 4, and the pallet 2 falls on the support plate 3. The conveyor belt 11 also clamps the pallet 2, and the servo motor 10 stops. After the longitudinal car 4 passes through the transverse car 1, the transverse car 1 takes the pallet 2 and the goods away to complete the operation; by setting up a transmission mechanism, when the transverse car 1 and the longitudinal car 4 hand over the goods, the action is continuous, and the longitudinal car 4 always keeps moving, reducing the pause time, shortening the handover time, and improving work efficiency.

[0023] In other embodiments, the present embodiment discloses, please Figure 4 and Figure 5 As shown, a mounting groove 15 is provided on the front surface of the lifting plate 5, a second spring 14 is fixedly connected to the inner side of the mounting groove 15, a damping block 16 is fixedly connected to the front end of the second spring 14, the front end of the damping block 16 passes through the mounting groove 15 and is located inside the slide groove 6, and a rubber block 17 is fixedly connected to the front end of the damping block 16;

[0024] When the lifting plate 5 enters the inner side of the slide groove 6 at a high speed, the rubber block 17 touches the inner wall of the slide groove 6 and is squeezed by the inner wall of the slide groove 6. The rubber block 17 pushes the damping block 16 to enter the inner side of the installation groove 15. At this time, the second spring 14 is forced to shrink. By setting the rubber block 17, the damping block 16 and the second spring 14, the potential energy generated by the impact is absorbed, the damage to the equipment caused by the impact is reduced, and the service life of the transverse car 1 and the longitudinal car 4 is improved.

[0025] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
