Description

Technical Field

[0001] The utility model relates to the technical field of chassis for unmanned vending trucks, and in particular to a chassis for unmanned vending trucks. Background Art

[0002] Unmanned vending trucks are a type of self-service vending device that has emerged in recent years. They are widely used in parks, smart scenic spots, commercial streets, parks, squares and other places, and can provide mobile vending services. Unmanned vending trucks are composed of multiple components, among which the chassis is an important component of the unmanned vending truck. Its function is to support and install the various parts of the car.

[0003] At present, the chassis of existing unmanned vending trucks is usually of fixed height. Therefore, when the truck passes through a road with a large slope or a raised obstacle on the road, the chassis is prone to direct collision and friction with the ground, which can easily cause scratches and damage to the chassis, thus affecting the service life of the chassis. To this end, we propose a chassis for unmanned vending trucks to solve the above problem. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5A chassis for an unmanned vending truck includes a vending truck chassis 1, a protective plate 2 is distributed at the bottom end of the vending truck chassis 1, and a connecting plate 3 is symmetrically provided on the upper surface of the protective plate 2, and the top of the connecting plate 3 is respectively vertically connected with a buffer spring 4, and the top of the buffer spring 4 is connected to the bottom wall of the vending truck chassis 1, and the ends of the connecting plate 3 are respectively connected with a vertical pole 14, and the interior of the vertical pole 14 is respectively provided with an insertion groove 5, and the interior of the insertion groove 5 is inserted with an insertion rod 7, and the top of the insertion rod 7 is connected to the vending truck chassis 1, and the protective plate 2 can be guided by the vertical pole 14 and the insertion groove 5 opened therein, and in combination with the setting of the insertion rod 7, to ensure the stable up and down movement of the protective plate 2, so as to ensure the stability of the protective plate 2. In order to prevent multiple groups of buffer springs 4 from being skewed when subjected to force and to ensure the buffering effect of the buffer springs 4, mounting plates 8 are symmetrically distributed on the outer sides of the connecting plate 3, and the bottom ends of the mounting plates 8 are connected to the protective plate 2. Threaded grooves are respectively provided at the front and rear ends of the mounting plates 8, and threaded rods 9 are inserted into the insides of the threaded grooves. The ends of the threaded rods 9 are connected to rotating blocks 10, and the bottom ends of the vertical rods 14 are provided with card grooves adapted to the threaded rods 9. The bottom ends of the connecting plates 3 and the vertical rods 14 are in contact with the upper surface of the protective plate 2. The four groups of mounting plates 8 arranged above the protective plate 2, in combination with the threaded rods 9 and the rotating blocks 10, can facilitate the staff to remove the damaged protective plate 2.

[0022] Further, see Figure 5 It can be known that the top of the protective plate 2 is connected with a reinforcing rib 13, and the reinforcing rib 13 is arranged in a cross-type structure. The reinforcing rib 13 arranged in a cross-type structure can improve the overall structural strength of the protective plate 2 to prevent it from being easily damaged.

[0023] Further, see Figure 3 and Figure 4 It can be known that the bottom ends of the insertion rods 7 are respectively connected to the movable disks 6, and the outer walls of the movable disks 6 are abutted against the inner walls of the insertion grooves 5. By abutting against the inner walls of the insertion grooves 5, the damping of the insertion rods 7 when moving up and down can be increased to further ensure the stability of the protective plate 2 up and down.

[0024] Further, see Figure 4 It can be seen that the side of the rotating block 10 is connected to the rotating rod 11, and the outer surface of the rotating rod 11 is evenly distributed with anti-slip particles. Through the cooperation between the rotating rod 11 and the anti-slip particles, it is convenient for the staff to drive the rotation of the rotating block 10, thereby effectively improving the convenience of the device during use.

[0025] Further, see Figure 3It can be known that grooves are evenly opened at the left and right ends of the protective plate 2, and balls 12 are installed inside the grooves. The installation method of the balls 12 is the existing technology. When the balls 12 are subjected to force, they can slide inside the grooves. The installation principle thereof will not be elaborated here. When the protective plate 2 passes through a road with a large slope or there are raised obstacles on the road surface, the balls 12 arranged at both ends of the protective plate 2 can roll, thereby converting the sliding friction into rolling friction, and achieving a second buffering of the impact force to protect the protective plate 2.

[0026] Working principle: When the utility model is in use, the staff can combine the fuselage of the unmanned vending truck with the chassis 1 of the vending truck, so as to complete the operation of unmanned vending. During the driving of the chassis 1 of the vending truck, if it passes through a road with a large slope or a raised obstacle on the road, the ground will first contact the protective plate 2, and then the protective plate 2 will be forced to push the buffer spring 4 to be squeezed and deformed. By setting multiple groups of buffer springs 4, the collision force between the protective plate 2 and the ground can be buffered. In addition, during the movement of the protective plate 2, the moving plate 6 and the insertion rod 7 will slide in the insertion groove 5 opened inside the vertical rod 14 to guide the protective plate 2, so as to ensure the stable up and down translation of the protective plate 2.

[0027] When the protective plate 2 breaks after long-term use, the staff can rotate the rotating rod 11 in sequence, thereby driving the rotating block 10 to rotate at the same time, so as to pull the threaded rod 9 out from the inside of the vertical rod 14 and the mounting plate 8, and then the mounting plate 8 and the connecting plate 3 connected to the upper side of the protective plate 2 can be separated, thereby realizing the rapid disassembly of the protective plate 2. The above is the entire working principle of the utility model.

[0028] In the present invention, the installation method, connection method or setting method of all the components mentioned above are common mechanical methods, and the specific structures, models and coefficient indicators of all its components are its own technology. As long as it can achieve its beneficial effects, it can be implemented, so it will not be elaborated.

[0029] The above embodiments are preferred implementation modes of the present invention, but the implementation modes of the present invention are not limited by the above embodiments. Any other changes, modifications, substitutions, combinations, and simplifications that do not deviate from the spirit and principle of the present invention should be equivalent replacement methods and are included in the protection scope of the present invention.

Moreover, the terms "include", "comprise" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device that includes a series of elements includes not only those elements, but also includes other elements that are not explicitly listed, or also includes elements inherent to such process, method, article or device.
