[0001] This utility model relates to the field of AGV vehicles, specifically to an integrated hydraulic device and an AGV vehicle. Background Technology
[0002] Currently, in conventional AGVs (Automated Guided Vehicles), especially counterbalanced AGVs, hydraulic components are scattered throughout the front compartment. Some are fixed to the front frame uprights, while others are fixed to the side frames; the arrangement varies from model to model, resulting in a relatively random and disorganized layout. This layout presents significant challenges to the assembly and manufacturing process, and imposes stringent requirements on the assembly sequence. Furthermore, it is inconvenient for after-sales maintenance. Replacing large assembly components may require prior disassembly of other hydraulic components in the front compartment, leading to substantial maintenance challenges and costs.

[0016] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention.

[0017] In the description of this utility model, terms such as "upper", "lower", "left", "right", "front", and "rear" are based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.
[0018] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.
[0019] Reference Figure 1 and Figure 2 As shown, this embodiment provides an integrated hydraulic device including a mounting plate 10, a pump motor assembly 21, an oil tank assembly 22, a multi-way valve 23, and a filter 24. The pump motor assembly 21, oil tank assembly 22, multi-way valve 23, and filter 24 are all fixedly mounted on the mounting plate 10. Specifically, the fixed connection between the above components and the mounting plate 10 can be achieved using existing technologies such as bolting, snap-fitting, or welding, as long as a fixed connection can be achieved; however, a detachable connection method such as bolting or snap-fitting is preferred. The mounting plate 10 has a connecting portion 11 for connecting to the vehicle frame 100.
[0020] Continue to refer to Figure 3 and Figure 4 As shown, this embodiment also provides an AGV vehicle, specifically a counterbalanced AGV vehicle, including a frame 100 and the aforementioned integrated hydraulic device. The integrated hydraulic device is fixed to the frame 100 via a mounting plate 10. This configuration allows the hydraulic components to be pre-assembled before vehicle production. Specifically, the pump motor assembly 21, oil tank assembly 22, multi-way valve 23, and filter 24 are all fixedly mounted on the mounting plate 10 to form the integrated hydraulic device. The integrated hydraulic device is then hoisted onto the frame 100 and connected to the frame 100 via the connecting part 11 of the mounting plate 10. This improves production and after-sales efficiency and reduces the number of brackets for fixed components, saving costs.
[0021] Specifically, the space constraints for fixing the pump motor assembly 21, oil tank assembly 22, multi-way valve 23, and filter 24 to the mounting plate 10 are relatively small, meaning there are no spatial constraints or limitations between the components. Therefore, each component can be flexibly installed. In this embodiment, the mounting plate 10 is a vertically arranged plate, and the pump motor assembly 21, oil tank assembly 22, multi-way valve 23, and filter 24 are all fixedly assembled on the same vertical surface of the mounting plate 10. Specifically, the oil tank assembly 22 is located at the bottom, and the pump motor assembly 21, filter 24, and multi-way valve 23 are located above the oil tank assembly 22 and distributed sequentially from left to right. Of course, in other embodiments, the positional relationship of the upper pump motor assembly 21, filter 24, and multi-way valve 23 can be arranged arbitrarily, or the pump motor assembly 21, oil tank assembly 22, multi-way valve 23, and filter 24 can be distributed on the front and rear vertical surfaces of the mounting plate 10, and so on.
[0022] Specifically, after the pre-assembled components (i.e., the aforementioned integrated hydraulic device) are installed into the frame 100, the various components can be connected accordingly. These connections are existing technologies. For example, the oil tank assembly 22 is connected to the pump inlet of the pump motor assembly 21 via a sizing tube, and both ends of the sizing tube are locked with clamps; the pump outlet of the pump motor assembly 21 is connected to the inlet of the filter 24 via an oil pipe, and the outlet of the filter 24 is connected to the inlet of the multi-way valve 23; the return port of the multi-way valve 23 is connected to the return port of the oil tank assembly 22; and the other ports of the multi-way valve 23 are connected to the corresponding actuators (such as cylinders, masts, etc.).
[0023] The mounting plate 10 is a vertically oriented plate, reducing its horizontal footprint. Specifically, the connecting part 11 includes a top connecting part 111 at the top of the mounting plate 10 and a supporting part 112 at the bottom of the mounting plate 10. The top connecting part 111 is used to form a fixed installation or a limiting installation with the frame 100. In this embodiment, it is a limiting installation, that is, the top connecting part 111 limits the mounting plate 10 to the frame 100. The supporting part 112 is used to abut against the frame 100 to support the mounting plate 10. The limiting installation ensures stable installation and eliminates the need for locking. During maintenance, it can be directly lifted upwards, which is beneficial for subsequent maintenance operations. Of course, in other embodiments, the top connecting part 111 can also form a fixed installation with the frame 100, or the mounting plate 10 can be fixedly connected to the frame 100 at other locations, or the mounting plate 10 can be a horizontally extending plate with each component fixed to its upper surface, etc.
[0024] Furthermore, the pump motor assembly 21, oil tank assembly 22, multi-way valve 23, and filter 24 are all fixedly mounted on the same vertical surface of the mounting plate 10, and this vertical side is defined as the first vertical surface, and the other vertical surface is defined as the second vertical surface; the top end of the mounting plate 10 is bent in a direction away from the first vertical surface (i.e., towards the second vertical surface) to form a transverse extension 12, and the top end connecting part 111 is disposed on the transverse extension 12. In this way, the limiting component (i.e., the latch 101) on the frame 100 is offset from the insertion position and will not interfere with each other.
[0025] Specifically, the top connecting part 111 is a limiting rod part at the top of the mounting plate 10. In this embodiment, two limiting rod parts are provided, extending to the left and right sides. The frame 100 is provided with a latch 101, and the limiting rod parts protruding on both sides are engaged in the latch 101 to achieve limiting cooperation. More specifically, in this embodiment, a shaft 113 is fixed to the top of the mounting plate 10, and the limiting rod part is the part of the shaft 113 that protrudes from the mounting plate 10. Of course, in other embodiments, the limiting rod part can also be integrally extended from the mounting plate 10.
[0026] Furthermore, the limiting rod is fitted with a buffer sleeve (defined as the first buffer sleeve 114), such as a rubber bushing, to provide buffer protection.
[0027] Specifically, the support portion 112 includes a crossbar 115 fixed to the bottom of the mounting plate 10 and a buffer sleeve (defined as a second buffer sleeve 116) sleeved on the crossbar 115; an abutment seat 102 is provided on the frame 100, and the support portion 112 is fitted within the abutment seat 102 to achieve a positioning fit. This also prevents the support portion 112 from disengaging from the abutment seat 102 and causing displacement.
[0028] Furthermore, in this embodiment, the mounting plate 10 is further provided with lifting arms 13 on both sides, and the lifting arms 13 are provided with lifting holes 14 for use with external lifting equipment to achieve lifting and installation.
[0029] Furthermore, in this embodiment, the mounting plate 10 is provided with a first maintenance window 15 corresponding to the filter 24 and a second maintenance window 16 corresponding to the pump motor assembly 21. When the filter 24 or the pump motor assembly 21 is inspected separately, it can be inspected through the first maintenance window 15 or the second maintenance window 16 without having to remove the entire assembly, which is faster and simpler.
[0030] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
