Detailed Implementation

[0024] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0025] Embodiments of this utility model: such as Figures 1-8 As shown, an AGV forklift frame includes a chassis 1, a front axle 2 at the front end of the chassis 1, a rear axle 3 at the rear end of the chassis 1, a battery compartment 7 at the top of the chassis 1, a left door 4 on the left side of the battery compartment 7, a right door 6 on the right side of the battery compartment 7, and a battery 8 installed inside the battery compartment 7.

[0026] This product features a double-door design. Opening the left door 4 allows for convenient maintenance and inspection of the circuitry, while opening the right door 6 facilitates the installation and removal of the battery 8. This product eliminates the need for a driver's seat and overhead guard, improving the AGV forklift's maneuverability. Forklifts using this product have a lighter overall weight, which helps improve their mobility and energy efficiency.

[0027] Specifically, this product has a three-point frame structure. The drive system and two drive wheels are mounted on the front axle 2 of the frame, and a steering wheel is mounted on the rear axle 3 of the frame. The drive system, drive wheels, and steering wheel are all existing technologies and can be installed using conventional methods, so they will not be described in detail in this embodiment.

[0028] Furthermore, a mounting plate 9 is fixedly installed on the left side of the battery compartment 7, and a charging plate 5 is installed on the left side of the mounting plate 9. The charging plate 5 is electrically connected to the battery 8.

[0029] Specifically, a charging board bracket 51 is welded and fixed on the left side of the mounting plate 9. A maintenance and heat dissipation space 52 is reserved on the top of the charging board bracket 51. The charging board 5 is fixedly installed on the charging board bracket 51 by four bolt assemblies.

[0030] Both the left door 4 and the right door 6 have a maximum opening angle greater than 120°. Opening the left door 4 fully exposes the charging panel 5, facilitating its maintenance and inspection. Opening the right door 6 fully exposes the battery 8, allowing it to be removed from the battery compartment 7 for charging, replacement, or other maintenance.

[0031] Furthermore, a U-shaped opening 10 is provided on the chassis 1. The opening of the U-shaped opening 10 is located on the right side of the chassis 1. Battery base plates 72 are fixed on both the front and rear sides of the U-shaped opening 10 on the top surface of the chassis 1. A battery baffle 73 is formed at the right end of the battery base plate 72.

[0032] The battery base plate 72 is a long strip of flat plate. Setting the battery base plate 72 can better avoid the weld seam between the vehicle chassis 1 and the battery compartment 7, and can obtain a flat bottom of the battery compartment.

[0033] Furthermore, a battery front and rear limiting block 75 is provided on the rear side wall inside the battery compartment 7, and a battery inner limiting block 76 is fixed on the right side wall of the mounting plate 9. The left side wall of the battery 8 is fixedly connected to the battery inner limiting block 76 by bolts.

[0034] The front and rear limit blocks 75 of the battery are bolted to the rear side wall of the battery compartment. By adjusting the bolts, the position of the front and rear limit blocks 75 can be changed to hold the battery 8 in place, preventing the battery 8 from moving forward or backward. The inner limit block 76 of the battery is a U-shaped limit plate. The battery 8 is fixedly connected to the inner limit block 76 by bolts, which can restrict the battery's degrees of freedom in all directions and prevent the battery 8 from moving. The battery baffle 73 can effectively restrict the battery 8 from moving to the right.

[0035] After the battery 8 is installed in the battery compartment 7, there is an upper space 74 between the top of the battery 8 and the top plate inside the battery compartment 7. The upper space 74 facilitates the installation and removal of the battery 8 and provides heat dissipation space for the battery 8.

[0036] A C-shaped battery compartment tie beam 71 is fixedly installed on the upper right side of the battery compartment 7. The battery compartment tie beam 71 can fix the opening size of the battery compartment 7.

[0037] Furthermore, the left door 4 and the right door 6 have the same structure. Both include two folding plates 41, a stiffening frame 42, a door lock 43, and a door hinge 44. One side of the two folding plates 41 is hinged to the battery compartment 7 through two door hinges 44. A U-shaped stiffening frame 42 is fixed on the inner wall of the two folding plates 41, and the door lock 43 is located on the other side of the two folding plates 41.

[0038] The stiffener frame 42 is a U-shaped frame made of stiffeners welded together and fixed to the two folded plates 41 to form a side door with a sturdy frame structure.

[0039] The U-shaped opening 10 creates an open battery compartment 7 on the product, which facilitates air circulation and better dissipates heat from the forklift's battery, motor, and other heat-generating components. This prevents the equipment from overheating, reducing its performance or causing malfunctions, and extends its service life.

[0040] Compared to traditional enclosed frames, this product allows the charging pad 5 to be fully exposed by opening the left side door 4, facilitating quick maintenance and inspection. Opening the right side door 6 fully exposes the battery 8, making it easy to remove the battery 8 from the battery compartment 7 for charging or replacement.

[0041] When the battery 8 needs to be removed for replacement, it must first be lifted using an external device. Utilizing the upper space 74 of the battery, once the height exceeds the battery baffle 73, the battery 8 can be removed from the battery compartment 7.

[0042] The above description, based on the embodiments shown in the drawings, details the structure, features, and effects of this utility model. The above description is only a preferred embodiment of this utility model, but the scope of implementation of this utility model is not limited to what is shown in the drawings. Any changes made in accordance with the concept of this utility model, or modifications to equivalent embodiments, that do not exceed the spirit covered by the specification and drawings, shall be within the protection scope of this utility model.
