Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of AGV transport vehicle frame, specifically relating to a transport vehicle frame. Background Technology
[0002] Automated Guided Vehicles (AGVs) are battery-powered industrial vehicles that operate automatically. They are also known as automated guided vehicles or AGV carts. AGV carts load goods automatically or manually, and then automatically travel along a pre-set route or pull a cargo trolley to a designated location to complete the transport of goods.
[0003] The chassis is the core component of the AGV (Automated Guided Vehicle) body. It provides a solid structural foundation for the AGV, ensuring its stability under various operating conditions. At the same time, the chassis is the platform for installing key components such as wheels, sensors, batteries, motors, and reducers. A good chassis structure can bring good operational stability to the AGV.
[0004] AGV (Automated Guided Vehicle) transport carts are generally suitable for hard cement floors, plastic floors, and epoxy flooring, but these surfaces cannot always remain flat. Currently, AGV cart frames lack adjustment capabilities, making it impossible to adjust the position of the wheels according to different terrains and angles. This causes some wheels to detach from the ground or slip when encountering uneven surfaces during movement. In particular, when the drive wheels of single-drive AGVs detach from the ground, the cart will be unable to move forward, resulting in unstable operation. Utility Model Content

[0018] This invention ensures that the wheels on the frame always remain in contact with the ground, improving the overall stability and reliability of the frame. It can automatically adapt to uneven road surfaces, exhibiting strong adaptability. The frame of this application uses a pivot as a support point, rotating up and down on both sides of the pivot. When the road surface is flat, the wheels are in contact with the ground, allowing for stable operation. When the ground is uneven, the frame tilts around the pivot, creating a tilt with one end higher than the other. The wheels on the frame tilt accordingly, automatically adjusting their position based on the unevenness of the ground to prevent separation of the wheels from the ground. This ensures that the wheels on the frame always remain in contact with the ground, improving the overall stability and reliability of the frame and allowing for automatic adaptation to uneven road surfaces, exhibiting strong adaptability.

[0029] Example 1:
[0030] like Figures 1 to 4 As shown, a transport vehicle frame includes: a frame body 1, an adjustment frame 2, and wheels 3; the frame body 1 has a hollow structure to reduce its weight; the adjustment frame 2 includes a spur 21 and a rotating shaft 22; the rotating shaft 22 is horizontally positioned at the middle of one end of the frame body 1; the length direction of the rotating shaft 22 is consistent with the length direction of the frame body 1; the frame body 21 is rotatably mounted on the rotating shaft 22; the length direction of the frame body 21 is consistent with the width direction of the frame body 1; the frame body 21 is located below the frame body 1, that is, the frame body 21 rotates below the frame body 1; preferably, the frame body 21 has a hollow structure to reduce the overall weight; the wheels 3 are mounted on the frame body 1 and the frame body 21, wherein the wheels are located below the frame body 1 and the frame body 21, and the wheels 3 on the frame body 21 are located at both ends of the frame body 21.
[0031] Work style:
[0032] The frame 21 of this application uses the pivot 22 as a support point and rotates up and down on both sides of the pivot 22. When the road surface is flat, the traveling wheels 3 are in contact with the ground and run smoothly. When the ground is uneven, the frame 21 uses the pivot 22 as a support point and rotates and tilts, forming a shape where one end is high and the other end is low. The traveling wheels 3 on the frame 21 tilt with the frame 21 and automatically adjust the position of the traveling wheels 3 on the frame 21 according to the unevenness of the ground to prevent the traveling wheels from separating from the ground. This ensures that the traveling wheels on the frame 21 always keep in contact with the ground, improves the stability and reliability of the overall frame, and can automatically adapt to uneven road surfaces, making it highly adaptable.
[0033] Example 2:
[0034] like Figures 1 to 4 As shown, compared with Embodiment 1, the difference lies in that a structural form of the traveling wheel 3 is given; the traveling wheel 3 includes a drive wheel 31 and a driven wheel 32; the traveling wheel 3 is disposed on the frame body 1 and the frame 21; the traveling wheel 3 is located below the frame body 1 and the frame 21 and is in contact with the ground; preferably, the drive wheel 31 is a steering wheel, which has strong adaptability, high control precision and flexibility, and can be applied to various scenarios; at least one drive wheel 31 and one driven wheel 32 are provided on the frame 21 and the frame body 1 to form a front and rear dual drive, which enhances power and steering ability.
[0035] like Figure 4 As shown, preferably, the drive wheels 31 on the frame 21 and the drive wheels 31 on the chassis body 1 are diagonally distributed to ensure that in areas with large road unevenness, there is always one drive wheel 31 in contact with the ground to provide power.
[0036] like Figure 2 and Figure 4 As shown, preferably, the adjustment frame 2 also includes a plate 23; since the frame 21 is a hollow structure with limited installation area, the traveling wheels 3 on the adjustment frame 2 need to be set on the frame 21 through the plate 23; one side of the plate 23 is connected to the bottom surface of the frame 21, and the other side is connected to the traveling wheels 3. The overall structure is simple and the design is reasonable.
[0037] Example 3:
[0038] like Figures 1 to 5As shown, compared with Embodiment 2, the difference is that the frame body 1 also includes a first bracket 11; the driven wheel 32 on the frame body 1 is connected to the frame body 1 through the first bracket 11; the top end of the first bracket 11 is connected to the bottom surface of the frame body 1 away from the frame 21, and the other end is connected to the driven wheel 32; because there is a height difference between the driven wheel 32 on the adjustment frame 2 and the driven wheel 32 on the frame body 1, the first bracket 11 is needed to reduce the height difference between the adjustment frame 2 and the driven wheel on the frame body 1; preferably, the top end of the first bracket 11 is an open structure, so that the first bracket 11 can place equipment components, such as remote control receivers.
[0039] like Figures 1 to 5 As shown, preferably, the frame body 1 also includes a second bracket 12; the top of the second bracket 12 is connected to the bottom of the middle part of the frame body 1; the top of the second bracket 12 is an open structure, so that the second bracket 12 can place equipment components, such as batteries, controllers, etc.; the bottom of the second bracket 12 is higher than the bottom of the driving wheel 3 to prevent the second bracket 12 from being bumped.
[0040] like Figure 4 Preferably, the walking wheels 3 are distributed directly below the four corners of the frame body 1, forming a four-wheel walking system.
[0041] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
