[0020] To enable those skilled in the art to better understand the present application, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present application, and not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative effort should fall within the scope of protection of the present application.

[0021] According to an embodiment of this utility model, an AGV vehicle body structure is provided. Please refer to [link / reference]. Figures 1 to 4It includes: a vehicle body 1; a traveling assembly 2, which is mounted on the vehicle body 1 and is used to move the vehicle body 1; and an anti-rollover assembly 3, which is mounted on the vehicle body 1 and has a support part and an auxiliary moving part. The anti-rollover assembly 3 has a normal driving state and an anti-rollover working state. In the normal driving state, the bottom end of the auxiliary moving part is higher than the bottom end of the traveling assembly 2. In the anti-rollover working state, when the traveling assembly 2 is suspended or the vehicle body 1 tilts, the bottom end of the auxiliary moving part contacts the ground or the track.

[0022] By adopting the above technical solution, and by setting up an anti-tipping component 3 with two modes, namely normal driving state and anti-tipping working state, the auxiliary moving part is raised under normal circumstances so as not to affect the normal driving of the AGV. When the walking component 2 is suspended, it contacts the ground to provide immediate support for the vehicle body 1. This effectively prevents the AGV from overturning when crossing the track or uneven ground, and significantly improves the operational safety.

[0023] Please refer to Figure 4 The anti-rollover component 3 includes: a mounting component 4, which is mounted on the vehicle body 1; and an auxiliary wheel 5, which is rotatably disposed at the bottom of the mounting component 4. In normal driving conditions, the bottom end of the auxiliary wheel 5 is higher than the bottom end of the traveling component 2. In the anti-rollover working condition, when the traveling component 2 is suspended or the vehicle body 1 tilts, the bottom end of the auxiliary wheel 5 contacts the ground or the track, wherein the auxiliary wheel 5 forms an auxiliary moving part.

[0024] By adopting the above technical solution, the auxiliary moving part is specifically set as a rotatable auxiliary wheel 5, and it is installed on the vehicle body 1 through the mounting part 4. When the anti-overturning state is triggered, the auxiliary wheel 5 can contact the ground in a rolling manner, which not only provides effective support, but also avoids rigid sliding friction with the ground. This achieves the effect of preventing overturning while assisting the vehicle body 1 to move, reducing resistance and protecting the ground.

[0025] Furthermore, the auxiliary wheels 5 are preferably configured as two, and both auxiliary wheels 5 are rotatable.

[0026] By adopting the above technical solution and setting two rotatable auxiliary wheels 5, the contact area with the ground and the stability of the support point are increased, so that the anti-overturning component 3 can provide more balanced support force when it intervenes, thereby further improving the reliability of the anti-overturning capability and preventing the possible off-center loading or instability of single-point support.

[0027] Furthermore, the mounting bracket includes: a first mounting plate 6, which is detachably mounted on the vehicle body 1 and extends vertically, located on the side of the traveling assembly 2 near the middle of the vehicle body 1; and a second mounting plate 7, which is connected to the first mounting plate 6 and extends perpendicularly to the extension direction of the first mounting plate 6.

[0028] By adopting the above technical solution, and by using the mounting component 4 composed of the first mounting plate 6 and the second mounting plate 7 that are perpendicular to each other, a solid and accurately positioned mounting foundation is provided for the auxiliary wheel 5, ensuring that the spatial posture of the auxiliary wheel 5 meets the design requirements, and achieving the effect of ensuring the overall structural strength and installation accuracy of the anti-tipping component 3.

[0029] Furthermore, the first mounting plate 6 and the second mounting plate 7 are connected by a reinforcing plate 8 to increase the stability of the connection.

[0030] By adopting the above technical solution, and by setting a reinforcing plate 8 to connect the first mounting plate 6 and the second mounting plate 7, the rigidity and torsional resistance of the connection between the two are enhanced, preventing deformation or breakage when subjected to impact or heavy load, thus achieving the effect of ensuring the long-term stable operation of the mounting component 4 and extending its service life.

[0031] Please refer to Figure 4 The anti-tipping assembly 3 also includes: a rotating component 9, which is installed at the bottom of the mounting component 4; a buffer component 10, one end of which is connected to the rotating component 9; and the end of the buffer component 10 away from the rotating component 9 is connected to the auxiliary wheel 5.

[0032] Among them, the buffer element 10 constitutes a buffer section.

[0033] By adopting the above technical solution, by setting a rotating part 9 and a buffer part 10 between the mounting part 4 and the auxiliary wheel 5, the auxiliary wheel 5 can buffer the impact force and adapt to the slight unevenness of the ground at the moment of contact with the ground and during the subsequent support process, thus achieving the effects of smooth contact, vibration absorption, and protection of the auxiliary wheel 5 and the vehicle body 1 structure.

[0034] Furthermore, there are two buffers 10, and the two buffers 10 are respectively connected to the two auxiliary wheels 5 on opposite sides.

[0035] Specifically, the rotating component 9 is a rotating bearing, which is mounted on the bottom of the second mounting plate 7 via a bearing seat 11.

[0036] By adopting the above technical solution, by configuring two buffer components 10 for the two coaxially connected auxiliary wheels 5, and using a rotating bearing as a rotating component 9, the buffering and swinging functions of the auxiliary wheels 5 are realized, enabling them to better adapt to complex ground conditions, and further improving the adaptability of the anti-overturning system to the terrain and the uniformity of the buffering effect.

[0037] Please refer to Figure 4 The anti-overturning assembly 3 also includes a connector 12, one end of which is connected to the rotating member 9, and the other end of which is connected to the buffer member 10.

[0038] By adopting the above technical solution, and by setting a special connector 12 to connect the rotating part 9 and the buffer part 10, the force transmission path is optimized, ensuring the smooth operation of the buffer action, and achieving the effect of enhancing the overall structural continuity and operational reliability of the buffer part 10.

[0039] Please refer to Figure 4 The buffer 10 includes: a damping telescopic rod 13, one end of which is connected to the rotating member 9; an L-shaped plate 14, with the auxiliary wheel 5 rotatably disposed relative to the L-shaped plate 14, and the end of the damping telescopic rod 13 away from the rotating member 9 connected to the L-shaped plate 14.

[0040] By adopting the above technical solution, the buffer 10 is constructed by combining the damping telescopic rod 13 and the L-shaped plate 14. The damping telescopic rod 13 provides controllable damping force and telescopic stroke, while the L-shaped plate 14 provides a stable mounting platform for the auxiliary wheel 5, thus achieving the effect of efficient energy absorption and stable support.

[0041] Please refer to Figure 4 The buffer 10 also includes a telescopic spring 15, which is sleeved on the damping telescopic rod 13 and is located between the rotating part 9 and the L-shaped plate 14.

[0042] By adopting the above technical solution, by sleeved a telescopic spring 15 on the damping telescopic rod 13, the elastic restoring characteristics of the spring are combined with the energy dissipation characteristics of the damper, which can assist the auxiliary wheel 5 to reset after buffering, thereby achieving the effect of improving the response speed and continuous working capacity of the buffer system.

[0043] Please refer to Figure 4 The connector 12 includes: a connecting plate 16, which extends vertically and is connected to the rotating member 9; and a movable plate 17, one side of which is rotatably connected to the connecting plate 16, and the side of the movable plate 17 near the connecting plate 16 is rotatably connected to the L-shaped plate 14.

[0044] By adopting the above technical solution, the rotating part 9 and the buffer part 10 are connected by a hinge mechanism composed of the connecting plate 16 and the movable plate 17, allowing the buffer part 10 and the auxiliary wheel 5 to swing around the axis within a certain range, thereby enabling the auxiliary wheel 5 to have a certain adjustment capability, so as to better fit the ground and optimize the force state.

[0045] Furthermore, an arc-shaped portion is provided on the top of the movable plate 17 near the L-shaped plate 14. The arc-shaped portion extends along a preset arc trajectory to avoid the L-shaped plate 14 during rotation and prevent motion interference.

[0046] By adopting the above technical solution, by setting a specific shaped arc part on the movable plate 17, the necessary movement space is provided for the L-shaped plate 14 during the swinging process, avoiding movement interference, ensuring the smooth realization of the buffering and swinging functions, and achieving the effect of ensuring the reliability of the anti-tipping component 3.

[0047] Please refer to Figure 3 The traveling component 2 includes four traveling wheels 18, with two traveling wheels 18 on one side of the vehicle body 1 and two traveling wheels 18 on the other side of the vehicle body 1. Specifically, an anti-tipping component 3 is provided between the two traveling wheels 18 on one side of the vehicle body 1, and the anti-tipping component 3 is provided on the side where the two traveling wheels 18 are close to each other. The other side of the vehicle body 1 is configured in the same way. By providing an anti-tipping component 3 on the side of the outermost traveling wheel 18, the anti-tipping component 3 can contact the ground or the track when the outermost traveling wheel 18 is suspended in the air, thereby increasing the stability of the vehicle body 1.

[0048] By adopting the above technical solution, an anti-tipping protection network is constructed around the vehicle body 1 by arranging anti-tipping components 3 at key positions on both sides of the vehicle body 1 and between the traveling wheels 18, with particular emphasis on the vicinity of the outermost traveling wheel 18. When any traveling wheel 18 in any direction is suspended due to uneven ground, the adjacent anti-tipping component 3 can immediately intervene to provide support, achieving all-round prevention of rollover and greatly improving the stability of AGV operation under various complex road conditions.

[0049] Please refer to Figure 2 It also includes: a lifting assembly 19, which is mounted on the vehicle body 1. The lifting assembly 19 includes: a support frame 20, which is movably mounted in the vertical direction; and a drive member 21, which is mounted on the vehicle body 1. The telescopic end of the drive member 21 is connected to the support frame 20, and the drive member 21 is telescopically mounted in the vertical direction.

[0050] By adopting the above technical solution and setting up a lifting component 19 that is directly driven by the drive component 21 to lift the support frame 20, the AGV is provided with stable and reliable cargo lifting and lowering functions, which meets the basic requirements of material handling and docking, and achieves the effect of realizing automated loading and unloading operations and expanding the functionality of the AGV.

[0051] Please refer to Figure 2 and Figure 3 The lifting assembly 19 further includes a scissor arm assembly 22, which is disposed between the vehicle body 1 and the support frame 20. The scissor arm assembly 22 includes a first scissor arm 23 and a second scissor arm 24 hinged together by a central pin. The lower end of the first scissor arm 23 is hinged to the vehicle body 1, and the upper end of the first scissor arm 23 is slidably connected to the support frame 20. The lower end of the second scissor arm 24 is slidably connected to the vehicle body 1, and the upper end of the second scissor arm 24 is hinged to the support frame 20.

[0052] By adopting the above technical solution, and by using the scissor arm assembly 22 to connect the drive component 21, the vehicle body 1 and the support frame 20, the vertical telescopic motion of the drive component 21 is converted into the smooth vertical lifting and lowering of the support frame 20. The scissor mechanism increases the lifting stroke and load-bearing stability, thereby achieving the effect of large stroke and high stability lifting of the support frame 20 and optimizing the structural layout.

[0053] Working principle: During normal operation, the vehicle body 1 is supported by the four wheels 18 of the walking assembly 2. At this time, the bottom of the auxiliary wheel 5 of the anti-tipping assembly 3 is raised above the bottom of the walking wheels 18 and does not contact the ground. When the AGV travels to the track connection or uneven road section, causing a certain walking wheel 18 to be suspended and the vehicle body 1 to tilt, the anti-tipping assembly 3 installed between the walking wheels 18 on both sides of the vehicle body 1 immediately enters the working state, and its auxiliary wheel 5 makes its bottom contact the ground or track. At the moment of contact, the impact force is transmitted through the L-shaped plate 14 to the buffer 10, the damping telescopic rod 13 and the sleeve. The telescopic springs 15 work together to absorb and buffer the impact, while the hinge mechanism consisting of the rotating part 9, the connecting part 12, and the movable plate 17 allows the auxiliary wheel 5 to adapt to minor unevenness of the ground; the two auxiliary wheels 5 together provide stable support for the vehicle body 1, preventing it from tipping over, and can assist in movement by rolling after contact; when the traveling wheel 18 touches the ground again, the auxiliary wheel 5 is lifted under the reset action of the telescopic spring 15, returning to the normal driving state; in addition, the scissor arm assembly 22 can be driven by the drive part 21 to move, so as to realize the lifting and lowering of the support frame 20 to complete the loading and unloading operation of materials.
