Description

Technical Field

[0001] The utility model relates to the technical field of automatic loading and unloading, and particularly relates to an automatic loading and unloading mechanism for a driverless vehicle. Background Art

[0002] With the continuous development of the unmanned economy and the logistics industry, driverless technology has been widely applied to the logistics distribution link. Based on the endurance, load capacity, infrastructure requirements of existing driverless vehicles, and the characteristics of small batch sizes, multiple types, large quantities of goods, and multiple loading and unloading points in the main application scenarios.

[0003] In Application No.: CN202221222276.0, an automatic loading and unloading system for a driverless van is disclosed, which includes a driverless van and a standard pallet robot. An automatic lifting cargo elevator is installed on the driverless van, and in cooperation with the standard pallet robot, automatic unmanned loading and unloading is achieved. However, the above design still has deficiencies. The lifting component lacks a buffer structure, and the guide groove rod is easily damaged due to impact force, which will shorten the service life of the guide groove rod.

[0004] Therefore, we propose an automatic loading and unloading mechanism for a driverless vehicle. Content of the Utility Model

[0005] The main purpose of the utility model is to provide an automatic loading and unloading mechanism for a driverless vehicle. Through the design of a buffer component, the guide groove rod can be protected. When the horizontal plate moves downward, the buffer component at the bottom end of the guide groove rod contacts the ground. Through the cooperation of the first buffer pad and the spring, the impact force generated when the guide groove rod descends can be released, avoiding direct contact between the guide groove rod and the ground, and thus extending the service life of the guide groove rod, and effectively solving the problems in the background art.

[0006] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0007] An automatic loading and unloading mechanism for a driverless vehicle includes a horizontal plate, an inclined plate, and guide groove rods. Two guide groove rods are arranged relatively parallel, and the two guide groove rods are connected by the horizontal plate. One end of the horizontal plate is fixedly connected with an inclined plate, and an extension plate is connected to the end of the inclined plate far from the horizontal plate. The inclined plate and the extension plate are both located between the two guide groove rods;

[0008] The bottom end of the guide groove rod is connected with a buffer component. Two groups of buffer components are arranged relatively parallel. The buffer component includes a mounting plate, a support member, a clamping plate, a rubber sleeve, a buffer seat, a spring, a first buffer pad, and a second buffer pad. A support member is integrally formed at the center of the lower end surface of the mounting plate. The bottom end of the support member is slidably connected with the buffer seat. A buffer cavity is arranged inside the buffer seat, and a clamping plate and a spring are respectively arranged inside the buffer cavity.

[0009] By adopting the above technical solution, the magnetic strip at one end of the inclined plate is inserted into the slot at one end of the extension plate, which can position the extension plate. One end of the first bolt passes through the inner wall of one end of the mounting hole and is threadedly connected to one end of the inclined plate, so that the extension plate and the inclined plate can be tightly connected. The end of the extension plate away from the inclined plate is inclined downward. Through the design of the extension plate, the length of the inclined plate can be extended, which is convenient for the standard pallet robot to move up and down the horizontal plate.

[0010] Specifically, the mounting plate is fixedly connected to the bottom end of the guide groove rod through a second bolt. One end of the support member away from the mounting plate passes through the top end of the buffer seat and is fixedly connected to the middle of the upper end surface of the clamping plate. A rubber sleeve is fixedly sleeved outside the clamping plate.

[0011] Specifically, second buffer pads are fixedly glued on both sides of the support member at the top end of the buffer seat, and a first buffer pad is fixedly glued at the bottom end of the buffer seat.

[0012] Specifically, a plurality of springs are arranged at equal intervals. The bottom end of the spring is fixedly connected to the inner wall of the bottom end of the buffer cavity, and the top end of the spring passes through the rubber sleeve and is fixedly connected to the lower end surface of the clamping plate.

[0013] Specifically, a protruding magnetic strip is fixedly inlaid in the middle of the end of the inclined plate away from the horizontal plate, and a slot adapted to the magnetic strip is provided in the middle of the end of the extension plate close to the inclined plate.

[0014] Specifically, the end of the extension plate away from the inclined plate is inclined downward. An installation hole for installing the first bolt is provided in the upper part of the end of the extension plate close to the inclined plate. One end of the first bolt passes through the inner wall of one end of the installation hole and is threadedly connected to one end of the inclined plate.
