[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] As attached Figures 1 to 4 The modular splicing frame structure of the high load-bearing AGV vehicle body shown includes a frame body 1, a bottom mounting groove 2, a transverse load-bearing bar 8 and a vertical load-bearing bar 10. The bottom mounting groove 2 is opened in the inner cavity of the front end face of the frame body 1. Extension piles 3 are set at the upper and lower ends of both sides of the frame body 1. A fixing column 4 is installed on the opposite face of every two sets of extension piles 3. A left connecting block 5 is installed on the outer surface of one set of fixing columns 4, and a bolt 6 is installed in the inner cavity of the left connecting block 5. A right connecting block 7 is installed on the outer surface of the other set of fixing columns 4.

[0025] A horizontal limiting rod 9 is installed at both the upper and lower ends of the inner cavity of the bottom mounting groove 2. A horizontal load-bearing rod 8 is installed on the outer surface of the horizontal limiting rod 9. A vertical limiting rod 11 is installed at the center of the inner cavity of the bottom mounting groove 2. Two sets of vertical limiting rods 11 are provided. A vertical load-bearing rod 10 is installed on the outer surface of the vertical limiting rod 11. A connecting load-bearing rod 12 is provided on the opposite face of the two sets of vertical load-bearing rods 10.

[0026] Among them: Frame body 1 serves as the foundation and main body of the entire structure, providing a platform for the installation and support of other components. It determines the overall shape and basic dimensions of the AGV body, bears various forces and loads during the entire AGV operation, and is the core component ensuring the integrity and stability of the body structure. Bottom mounting groove 2 provides installation positions for components such as the horizontal load bar 8 and the vertical load bar 10, playing a role in positioning and accommodating them, enabling these load bars to be accurately installed in predetermined positions, ensuring the accuracy and stability of the frame structure. It also helps to evenly transfer the load to the bottom of frame body 1, enhancing the overall load-bearing capacity. Extension piles 3 are set at the upper and lower ends on both sides of frame body 1, providing installation foundations for fixed columns 4. Fixed columns 4 are installed on the opposite side of extension piles 3, used to fix the left connecting block 5 and... The right connecting block 7 ensures that the connecting block can maintain a stable position during the splicing process, providing a reliable support point for the connection between the frames, making the splicing between the frames more robust. The fixing column 4 can make the installation position of the left connecting block 5 and the right connecting block 7 more accurate and stable, which helps to achieve precise splicing between the frames, and to a certain extent increases the structural strength and connection rigidity of the frame body 1, improving the stability of the entire frame structure. The bolt 6 is used to fasten the splicing between the left connecting block 5 and the right connecting block 7, so that they can be tightly connected together, ensuring that the splicing between the frames is firm and reliable, preventing the connection parts from loosening during AGV operation, ensuring the stability and safety of the entire frame structure. At the same time, the bolt 6 connection method is also easy to disassemble and repair, improving the convenience of maintenance.

[0027] The lateral limiting rod 9 is installed at the upper and lower ends of the inner cavity of the bottom mounting groove 2, which serves to limit and support the lateral load-bearing rod 8, ensuring that the lateral load-bearing rod 8 maintains the correct position and posture during load-bearing, preventing lateral displacement or swaying, and helping to evenly distribute the lateral load on the frame body 1, thereby improving the frame's lateral load-bearing capacity and stability. The lateral load-bearing rod 8 mainly bears the lateral load, and by being installed on the lateral limiting rod 9, it transmits the lateral force generated by the goods or equipment to the frame body 1. The vertical limiting rod 11 is installed at the center of the inner cavity of the bottom mounting groove 2, serving as the vertical load-bearing rod 10. Providing positioning and support ensures the accurate vertical position of the vertical load-bearing rod 10, restricts its vertical displacement during load-bearing, and enables the vertical load-bearing rod 10 to better bear the vertical load, thereby improving the stability and load-bearing capacity of the frame in the vertical direction. The connecting load-bearing rod 12 connects the two sets of vertical load-bearing rods 10, enhancing the connection strength and collaborative load-bearing capacity between the two sets of vertical load-bearing rods 10, enabling the vertical load-bearing rods 10 to better interact and support each other when bearing vertical loads, further improving the load-bearing capacity of the frame structure in the vertical direction, and ensuring the stability and reliability of the entire frame structure.

[0028] Example 2

[0029] Based on Example 1, the solution in Example 1 will be further described in detail below with reference to the specific working method, such as... Figures 1 to 4 As shown below, see details:

[0030] In a preferred embodiment, each set of left connecting blocks 5 and each set of right connecting blocks 7 together form a splicing structure, and the three sets of left connecting blocks 5 and the three sets of right connecting blocks 7 are arranged at equal intervals. Furthermore, multiple left connecting blocks 5 and right connecting blocks 7 are spliced ​​together to achieve the connection between the frames at multiple points. Compared with single-point connection, this multi-point connection method can distribute the load more evenly, reduce stress concentration at the connection point, and make the connection between the frames more stable. This ensures that even if the AGV is subjected to complex external forces during operation, the connection part is not easy to loosen or be damaged, thereby ensuring the stability of the entire vehicle structure.

[0031] In a preferred embodiment, the two ends of the lateral limiting rod 9 pass through both sides of the inner cavity of the bottom mounting groove 2 and are fixed with nuts. The two ends of the vertical limiting rod 11 pass through the upper and lower parts of the inner cavity of the bottom mounting groove 2 and are fixed with nuts. Furthermore, the lateral limiting rod 9 is fixed with nuts. When installing the lateral limiting rod 9, simply pass its two ends through both sides of the inner cavity of the bottom mounting groove 2 and tighten the nuts to complete the installation. The two ends of the vertical limiting rod 11 are fixed with nuts at the upper and lower parts of the inner cavity of the bottom mounting groove 2. This provides stable vertical support for the frame structure, restricts the displacement of components such as the vertical load-bearing rod 10 in the vertical direction, and enables the entire frame to better withstand vertical loads when carrying goods. This enhances the stability of the vehicle body in the vertical direction and prevents the AGV from being affected by excessive vertical deformation or causing structural damage.

[0032] In a preferred embodiment, when the transverse load bar 8 is sleeved on the outer surface of the transverse limiting bar 9, both ends of the transverse load bar 8 abut against both sides of the inner cavity of the bottom mounting groove 2. Furthermore, the transverse load bar 8 directly bears part of the load from above. When it is sleeved on the transverse limiting bar 9 and both ends abut against both sides of the inner cavity of the bottom mounting groove 2, its own strength enhances the load-bearing capacity of the frame body 1, expands the load transfer area, and enables the entire frame body 1 to better distribute the weight, thereby improving the overall load-bearing capacity of the high-load AGV vehicle body and ensuring its stability when transporting heavy objects.

[0033] In a preferred embodiment, when the vertical load bar 10 is sleeved on the outer surface of the vertical limiting bar 11, the two ends of the vertical load bar 10 abut against the upper and lower parts of the inner cavity of the bottom mounting groove 2, respectively. Furthermore, the vertical load bar 10 mainly bears the vertical load of the AGV body. When the two ends abut against the upper and lower parts of the inner cavity of the bottom mounting groove 2, it can evenly distribute the vertical force it bears to the entire bottom mounting groove 2, so that the AGV can safely and stably transport heavier goods.

[0034] In a preferred embodiment, the two ends of the connecting load-bearing rod 12 are respectively welded to one side of the opposite face of the two sets of vertical load-bearing rods 10, and the connecting load-bearing rod 12 is cylindrical in shape. Furthermore, the connecting load-bearing rod 12 connects the two sets of vertical load-bearing rods 10 to form a more stable overall structure. When the AGV body is under load, the connecting load-bearing rod 12 can effectively transmit and integrate the force on the two sets of vertical load-bearing rods 10, jointly bear and distribute the load, thereby improving the strength of the entire structure, enabling it to withstand greater weight, and reducing the risk of structural deformation and damage.

[0035] The working process of this utility model is as follows: First, the extension piles 3 are installed at the upper and lower ends on both sides of the frame body 1. Then, the fixing columns 4 are installed on the opposite sides of the extension piles 3. The left connecting blocks 5 and the right connecting blocks 7 are respectively installed on the two sets of fixing columns 4 on both sides of the frame body 1. There are three sets of left connecting blocks 5 and three sets of right connecting blocks 7. When it is necessary to splice to increase the length of the AGV, the ends of the two sets of frame bodies 1 are brought close to each other, so that the three sets of left connecting blocks 5 and three sets of right connecting blocks 7 are initially connected by bolts 6. The upper and lower ends of the bottom mounting groove 2 are installed in the inner cavity. Install the horizontal limiting rod 9. Before fixing, attach the horizontal load-bearing rod 8 to the outer surface of the horizontal limiting rod 9 so that its two ends abut against the two sides of the inner cavity of the bottom mounting groove 2. Then fix the two ends of the bottom mounting groove 2 with nuts. Install two sets of vertical limiting rods 11 at the center of the inner cavity of the bottom mounting groove 2. Similarly, attach the vertical load-bearing rod 10 to the outer surface of the vertical limiting rod 11 and fix the two ends with nuts so that its two ends abut against the upper and lower parts of the inner cavity of the bottom mounting groove 2. The two ends of the connecting load-bearing rod 12 are welded to one side of the opposite side of the two sets of vertical load-bearing rods 10 to form a whole.

[0036] During the operation of the AGV, the frame structure begins to bear various loads. The lateral force generated by the goods or equipment is transmitted from the lateral load bar 8 to the frame body 1 through the lateral limit bar 9; the vertical load is transmitted from the vertical load bar 10 to the bottom mounting groove 2 and then to the frame body 1 through the vertical limit bar 11. The connecting load bar 12 works in conjunction with the two sets of vertical load bars 10 to jointly bear and distribute the load. Through its own structural strength, the entire frame structure is guaranteed to have high stability and load-bearing capacity, enabling the AGV to complete the handling task safely and stably. The above is the working principle of the modular splicing frame structure of the high load-bearing AGV.
