[0041] Example 1

[0042] This embodiment provides an integrated chassis structure, such as Figure 1-7 As shown, the integral chassis structure includes a vehicle body 1 and a shell 2. The shell 2 is arranged at the edge of the vehicle body 1 and extends upward. The vehicle body 1 and the shell 2 are formed in one piece.

[0043] Existing AGV products require the separate design, production, and assembly of the body and shell structure, which results in complex design structure, increased product cost, and reduced assembly efficiency. This embodiment directly forms the body 1 and the shell 2 as one piece, reducing the design and assembly of parts, and solving the technical problems of complex structure, increased product cost, and reduced assembly efficiency caused by separate design of the body and shell in traditional AGVs.

[0044] In a specific embodiment, the shell 2 includes a front face 21 and a rear face 22, the front face 21 extends upward along one end of the vehicle body 1, and the rear face 22 extends upward along the other end of the vehicle body 1; the vehicle body 1, the front face 21 and the rear face 22 are integrally formed by a casting process.

[0045] Specifically, the shell and body of traditional AGV products are connected by welding, which is prone to being scrapped; in this embodiment, the body 1, the front face 21 and the rear face 22 are integrally formed by a casting process, wherein the casting process includes cast iron, cast aluminum and other casting processes, which are selected in combination with actual needs during the specific production process.

[0046] In addition, in traditional AGV products, when the sheet metal body and the plastic shell collide during actual use, the shell is easily damaged, which increases maintenance costs. This embodiment uses cast iron or cast aluminum to replace traditional sheet metal and plastic, avoiding the problem of easy damage to the shell after a collision.

[0047] In addition, the shell and body of traditional AGV products are designed separately and then connected together by welding. This method creates a gap between the shell and the body, which is extremely difficult to control and adjust, and is time-consuming and labor-intensive. In this embodiment, the body 1, the front face 21 and the rear face 22 are integrally formed through a casting process, which also avoids the existence of the gap.

[0048] In a specific embodiment, the general outline of the vehicle body 1 is a quadrilateral structure. Of course, each side of the quadrilateral has a corresponding structure, such as some depressions, or two adjacent sides are connected by an arc.

[0049] For better explanation, it is assumed that the first side and the third side of the vehicle body are two opposite sides, the second side and the fourth side are two opposite sides, and the first side and the third side are relatively short sides. The front face 21 of the vehicle is arranged at the edge of the first side and extends upward. Of course, the general outline of the front face 21 of the vehicle is an arc structure, which may extend to the second side and the fourth side. The rear face 22 of the vehicle is arranged at the edge of the third side and extends upward. Similarly, the general outline of the rear face 22 of the vehicle is also a house-type structure, which will extend to the second side and the fourth side.

[0050] In a specific embodiment, at least one first cavity 3 for achieving lightweight is formed on the vehicle body 1 .

[0051] Since the vehicle body 1 and the shell 2 are integrally formed in this embodiment and cast iron or cast aluminum is used, the weight of the entire chassis structure will increase. Therefore, in this embodiment, at least one first cavity 3 for achieving lightweight is provided on the vehicle body 1. The specific shape of the first cavity 3 is not limited and may be circular, elliptical or square.

[0052] In a specific embodiment, at least one reinforcing rib 4 is disposed on the bottom surface of the vehicle body 1 .

[0053] When more first cavities 3 are opened on the vehicle body 1, in order to ensure the structural strength of the vehicle body 1, at least one reinforcing rib 4 is provided on the surface of the vehicle body 1. When a plurality of reinforcing ribs 4 are provided, the reinforcing ribs 4 are cross-arranged transversely and longitudinally so that the structural strength of the vehicle body 1 meets the standards.

[0054] In a specific embodiment, the vehicle front face 21 and the vehicle rear face 22 both have a draft angle of not less than 1°.

[0055] In a specific embodiment, the vehicle front face 21 and the vehicle rear face 22 are both plate-like bodies extending along the edge of the vehicle body 1 ; along the direction from close to the vehicle body 1 to away from the vehicle body 1 , the thickness of the plate-like body decreases.

[0056] In a specific embodiment, the lower sections of the front face 21 and the rear face 22 are both provided with a second cavity 23 ; wherein the plate-like body includes an upper section 24 and a lower section 25 , and the thickness of the lower section 25 is greater than that of the upper section 24 .

[0057] Batch casting processes generally have a draft angle, which increases the difficulty of appearance design. In this embodiment, a second cavity 23 is opened on a thicker section (i.e., the lower section 25) of the front face 21 and the rear face 22 of the vehicle to avoid casting defects.

[0058] When the body 1 and the shell 2 are integrally formed, a deeper cavity will be formed. The deep cavity brings great difficulty to casting, and the minimum casting wall thickness and strength need to be considered. No deformation can occur so as not to affect the appearance shape. In a specific embodiment, the thickness of the upper section is not less than 5 mm; and / or the thickness of the lower section is not less than 8 mm.

[0059] In a specific embodiment, a plurality of mounting holes 5 are formed on the housing 2 .

[0060] The mounting hole 5 is not limited to the installation of components such as display screens, obstacle avoidance cameras, buttons 9, etc., but also includes other mounting positions for components that can be integrated, such as headlights 7, protective touch edges 8, etc. Figure 7 shown.

[0061] In addition, a top plate 6 is also provided on the integral chassis structure.

[0062] After the integral chassis structure of this embodiment is manufactured, it is necessary to perform processes such as grinding and puttying before the exterior painting to ensure the desired appearance. The mounting holes 5 of the display screen, buttons and other devices directly mounted on the casting exterior require high installation dimensional accuracy, and conventional casting blanks cannot meet the requirements. It is necessary to use composite mold sand to replace these places with high installation requirements.

[0063] The material of the integral chassis structure provided in this embodiment is not limited to cast iron, and can also be replaced by cast aluminum, cast steel, etc. The manufacturing process of the integral chassis structure is not limited to foundry cast iron, and can also be replaced by gravity casting, low pressure casting, high pressure casting, etc.

[0064] The integrated chassis structure provided in this embodiment includes a body and a shell, and does not need to be designed separately. In addition, it also integrates installation positions for components such as display screens, buttons, and indicator lights, which is a first in the AGV industry.

[0065] The integral chassis structure provided in this embodiment no longer requires a complex shell structure design, which reduces the design cycle and improves assembly efficiency; furthermore, the casting chassis has better consistency, which reduces the scrap rate of parts; in addition, the front and rear faces of the integral chassis structure are castings, which are much stronger than previous car shell designs and have a longer service life; in addition, the integral cast chassis does not have gaps, surface differences, etc. in the shell, and its overall performance is better than that of traditional separately designed sheet metal bodies and plastic shells.

[0068] In summary, it is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous technical features can be freely combined and superimposed.

[0069] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form.
