Specific implementation mode

[0022] Combined with the accompanying drawings in the embodiments of the present invention, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments; based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0023] Please refer to the attached Figure 1-6 , a four-way shuttle vehicle for multi-vehicle scheduling in this embodiment: including a vehicle body 1 and a drive wheel 2, grooves 3 are provided on four side edges of the vehicle body 1, support blocks 4 are provided in the four grooves 3, a support rod 5 is fixedly connected to the support block 4, a through hole for the support rod 5 to slide is provided on the vehicle body 1, an adjustment assembly for driving the four support rods 5 to open and close synchronously is provided in the vehicle body 1, the adjustment assembly includes a guide block 6, the guide block 6 is fixedly connected to the support rod 5, a guide hole 7 is opened on the guide block 6, a bracket 8 is slidably connected in the guide hole 7, the bracket 8 is fixedly connected to the vehicle body 1, and a driver for driving the four guide blocks 6 to slide synchronously is provided in the middle of the bracket 8.

[0024] The upper cross-section of the vehicle body 1 is of a square structure. The drive wheels 2 below the vehicle include transverse casters and longitudinal casters. There are two sets of transverse casters and two sets of longitudinal casters. The two sets of transverse casters are located on the left and right sides of the vehicle body 1, and the two sets of longitudinal casters are located on the front and rear sides of the vehicle body 1. A lifting platform is installed on the transverse casters or longitudinal casters. When the drive wheels 2 are working, only one of the transverse casters and longitudinal casters is in contact with the ground, thus ensuring the stability of the drive of the drive wheels 2 for the vehicle. The vehicle body 1 is the main part of the device. The interior of the vehicle body 1 houses electronic and mechanical components for controlling the movement of the device, and the exterior of the vehicle body 1 is used to carry the weight. The four grooves 3 around the vehicle body 1 are the same thickness as the vehicle body 1. Support blocks 4 are installed in all four grooves 3. The lower ground surface of the support blocks 4 is flush with the lower ground surface of the vehicle body 1. The four support blocks 4 can move linearly relative to the vehicle body 1. The support blocks 4 are slidably connected to the vehicle body 1 through support columns. The support columns can make the support blocks 4 spread out a certain length relative to the vehicle body 1, thereby increasing the bearing area of the four support blocks 4 and the upper end of the vehicle body 1. When placing large-volume objects, a larger range of support is provided for the objects, ensuring the stability of the support for the objects and preventing the objects from falling. There are two support rods 5 on the support blocks 4, and both support rods 5 are connected to the guide blocks 6. The bracket 8 guides the movement of the guide blocks 6 through the guide blocks 6, ensuring that the guide blocks 6 and the support rods 5 can slide stably.

[0025] The lower end of the self-locking rotating shaft 9 is connected to a worm gear reducer. The reverse self-locking ability between the worm gear and the worm ensures that the self-locking rotating shaft 9 will not rotate on its own after rotation. The rotation of the self-locking rotating shaft 9 drives the connecting block 10 to rotate. The four connecting rods 11 hinged on the connecting block 10 are distributed at an angle of 90 degrees. The distances from the four connecting rods 11 to the center of the self-locking rotating shaft 9 are the same. The input end of the worm gear and worm reducer is connected to a motor. When the motor works, the motor drives the self-locking rotating shaft 9 to rotate through the worm gear and worm reducer, and the self-locking rotating shaft 9 drives the connecting block 10 to rotate. As Figure 3 and Figure 4 shown, when the self-locking rotating shaft 9 drives the connecting block 10 to rotate counterclockwise, the connecting block 10 drives one end of the four connecting rods 11 to rotate counterclockwise, so that the other end of the connecting rod 11 drives the guide block 6 to slide outwards along the bracket 8. Since the four connecting rods 11 move synchronously and the angles of movement of the four connecting rods 11 are the same, the four guide blocks 6 drive the four support rods 5 and the support blocks 4 to expand outwards synchronously, increasing the loading area at the bottom of the device. Conversely, when the connecting block 10 rotates counterclockwise, the four support blocks 4 contract synchronously into the grooves 3.

[0026] Furthermore, in order to facilitate the outward extension of the support block 4 when carrying an object, a roller 12 is installed at the upper end of the support block 4. The roller 12 is rotatably connected to the support block 4. There are three rollers 12 on each support block 4. When moving the support block 4, the roller 12 contacts the object, and the dynamic friction between the roller 12 and the object can reduce the friction coefficient between the two, facilitating the outward extension and retraction of the support block 4.

[0027] The buffer wheel 13 is located on the side of the support block 4, and a part of the side of the buffer wheel 13 protrudes from the vehicle body 1. If a collision occurs during the movement of the vehicle body 1, the buffer wheel 13 touches the obstacle first. The buffer wheel 13 plays a role in shock absorption and buffering, protecting the vehicle body 1 and the load of the shuttle vehicle from damage. The buffer wheel 13 is made of wear-resistant and highly elastic materials such as rubber or polyurethane. The combined action of the buffer wheel 13, the slider 14 and the elastic member makes the shuttle vehicle more stable when encountering obstacles, reducing structural damage and load loss caused by impact and vibration. The elastic member is composed of a spring 16 and a cylindrical rod 15. The cylindrical rod 15 can play a good guiding and limiting role in the movement of the slider 14. The spring 16 has good elasticity, and the impact force of the collision of the buffer wheel 13 is offset by the elasticity of the spring 16 itself, ensuring the buffering effect of the buffer wheel 13 on the overall device.

[0028] Furthermore, in order to ensure the stability of the object carried on the vehicle body 1, an anti-slip pad 17 is installed at the upper end of the vehicle body 1. The anti-slip pad 17 is in a cross-shaped structure, which can increase the friction coefficient between the vehicle body 1 and the object and ensure the stability of the object.

[0029] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
