[0002] A forklift is an industrial handling vehicle, which refers to various wheeled handling vehicles used for loading and unloading, stacking and short-distance transportation of palletized goods.

[0003] At present, some forklifts are powered by new energy batteries. However, the batteries of existing forklifts are usually fixed in the battery compartment. When replacing the batteries, more cumbersome disassembly steps are required, and the installation steps are also more complicated, which is not conducive to the rapid replacement of batteries. Utility Model Content

[0004] The utility model aims to provide a small electric forklift battery compartment which is easy to replace and improves the convenience of replacing forklift batteries.

[0005] In order to solve the above technical problems, the utility model provides a small electric forklift battery compartment that is easy to replace, including a compartment body, a battery accommodating cavity opened inside the compartment body, and a conveyor belt rotatably arranged inside the battery accommodating cavity. The battery is placed on the conveyor belt, and the two ends of the conveyor belt are sleeved on the outer circumference of the roller, and the roller and the battery accommodating cavity are in movable cooperation. When the battery is placed on the conveyor belt, the two rollers move close to each other to form a groove on the upper surface of the conveyor belt for carrying the battery.

[0006] Furthermore, the end of the roller is connected to the inner wall of the battery accommodating cavity through a telescopic rod, and the roller and the telescopic rod are rotationally matched.

[0007] Furthermore, a positioning plate is provided inside the battery accommodating cavity. The positioning plate passes through the inner side of the conveyor belt, and both ends of the positioning plate are connected to the inner wall of the battery accommodating cavity so that when the battery is placed on the conveyor belt, the positioning plate supports the battery.

[0008] Furthermore, a top plate is telescopically provided on one side of the positioning plate close to the battery so that the top plate can push the battery.

[0009] Furthermore, a plurality of rollers are rotatably provided on one side of the top plate close to the battery.

[0010] Furthermore, a cover body is provided at the opening of the bin body, and a cover plate is provided on one side of the cover body extending toward the battery accommodating cavity, so that when the battery is placed on the conveyor belt, both sides of the battery are positioned by the cover plate and the conveyor belt respectively.

[0013] Furthermore, the end of the cover plate has a guiding arc surface.

[0014] The beneficial effect of the present utility model is that when installing the forklift battery into the warehouse body, the two rollers are first moved away from each other so that the conveyor belt is in a tensioned state. At this time, the upper surface of the conveyor belt is smooth. Then the battery is placed into the battery accommodating cavity through the opening of the warehouse body, and the battery is supported on the upper surface of the conveyor belt. At this time, the conveyor belt rotates and drives the battery into the battery accommodating cavity along with the conveyor belt. After the battery moves to the specified position, the two rollers move closer to each other, so that the conveyor belt gradually becomes loose, and then the battery is lowered downward, so that a groove structure is formed on the upper surface of the conveyor belt to limit the load of the battery.

[0015] When the battery needs to be disassembled and removed, the two rollers move away from each other again, causing the conveyor belt to tighten and lift the battery. Then, the conveyor belt rotates in the opposite direction to drive the battery to move out of the battery receiving cavity, and the battery disassembly operation can be completed quickly. Therefore, this solution can greatly improve the convenience of battery installation and disassembly. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0026] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field are within the scope of protection of the present invention.

Therefore, the above terms cannot be understood as limiting the present invention.

[0028] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the elements may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0029] like Figures 1-9 The utility model provides a small electric forklift battery compartment that is easy to replace, including a compartment body 1, a battery accommodating cavity 2 opened inside the compartment body 1, and a conveyor belt 3 rotatably arranged inside the battery accommodating cavity 2. The battery 4 is placed on the conveyor belt 3. The two ends of the conveyor belt 3 are sleeved on the outer periphery of the roller 5, and the roller 5 is in movable cooperation with the battery accommodating cavity 2. When the battery 4 is placed on the conveyor belt 3, the two rollers 5 move closer to each other to form a groove on the upper surface of the conveyor belt 3 for carrying the battery 4.

[0030] When installing the forklift battery 4 into the warehouse body 1, the two rollers 5 are first moved away from each other so that the conveyor belt 3 is in a tensioned state. At this time, the upper surface of the conveyor belt 3 is smooth. Then the battery 4 is placed into the battery accommodating cavity 2 through the opening of the warehouse body 1, and the battery 4 is supported on the upper surface of the conveyor belt 3. At this time, the conveyor belt 3 rotates and drives the battery 4 into the battery accommodating cavity 2 along the conveyor belt 3. After the battery 4 moves to the specified position, the two rollers 5 move closer to each other, so that the conveyor belt 3 gradually becomes loose, and then the battery 4 is lowered downward, so that a groove structure is formed on the upper surface of the conveyor belt 3 to limit the load of the battery 4.

[0031] When the battery 4 needs to be disassembled and removed, the two rollers 5 move away from each other again, so that the conveyor belt 3 is tightened and the battery 4 is lifted. Then, the conveyor belt 3 rotates in the opposite direction to drive the battery 4 to move out of the battery accommodating cavity 2, and the disassembly operation of the battery 4 can be completed quickly. Therefore, this solution can greatly improve the convenience of installing and disassembling the battery 4.

[0032] The warehouse body 1 is located on the chassis of the electric forklift.

[0033] Preferably, the end of the roller 5 is connected to the inner wall of the battery accommodating chamber 2 through a telescopic rod 6, and the roller 5 and the telescopic rod 6 are rotationally matched.

[0034] Specifically, when the two rollers 5 move away from each other, the telescopic rod 6 contracts to drive the rollers 5 away from each other, thereby ensuring that the conveyor belt 3 is tensioned. When the two rollers 5 move toward each other, the telescopic rod 6 extends to drive the rollers 5 toward each other, thereby ensuring that the conveyor belt 3 is loose.

[0035] The telescopic rod 6 is controlled to be telescopically extended and retracted by a hydraulic system to ensure that the two rollers 5 move synchronously.

[0036] In one embodiment of the present scheme, the roller 5 has a built-in motor, and the output end of the motor is connected to the telescopic rod 6, so that the motor controls the roller 5 to rotate relative to the telescopic rod 6. It is worth mentioning that in the present scheme, a motor can be set in both rollers 5, or a motor can be set in only one of the rollers 5, so that one roller 5 is an active roller and the other roller 5 is a driven roller.

[0037] Preferably, a positioning plate 7 is provided inside the battery accommodating cavity 2, the positioning plate 7 passes through the inner side of the conveyor belt 3, and the two ends of the positioning plate 7 are connected to the inner wall of the battery accommodating cavity 2, so that when the battery 4 is placed on the conveyor belt 3, the positioning plate 7 supports the battery 4.

[0038] Specifically, when the conveyor belt 3 is in a loose state, the battery 4 is located in the groove formed on the upper surface of the conveyor belt 3. Since the battery 4 is usually heavy, it is difficult for the conveyor belt 3 to carry it alone. At this time, the weight of the battery 4 can be supported by the positioning plate 7 to ensure the stability of the battery 4 during use and avoid damage to the conveyor belt 3.

[0039] Preferably, a top plate 8 is telescopically provided on one side of the positioning plate 7 close to the battery 4 , so that the top plate 8 pushes the battery 4 .

[0040] Specifically, when the battery 4 needs to be disassembled, the conveyor belt 3 needs to be reset to a tensioned state first. At this time, the top plate 8 can be extended relative to the positioning plate 7, so that the top plate 8 pushes and lifts the upper surface of the conveyor belt 3 and the battery 4, thereby assisting the conveyor belt 3 to be reset and the battery 4 to move.

[0041] Among them, the telescopic coordination of the top plate 8 and the positioning plate 7 is controlled by a hydraulic system, and the hydraulic system can be integrated with the hydraulic system of the telescopic rod 6, that is, when the telescopic rod 6 is extended, the top plate 8 is contracted, and when the telescopic rod 6 is contracted, the top plate 8 is extended, so as to ensure the synchronization between the two and improve the efficiency of disassembly and installation of the battery 4.

[0042] Preferably, a plurality of rollers 9 are rotatably provided on a side of the top plate 8 close to the battery 4 .

[0043] Specifically, due to the heavy weight of the battery 4 itself, when the battery 4 is located on the upper surface of the conveyor belt 3, the battery 4 will squeeze the conveyor belt 3 toward the top plate 8, so that the friction between the conveyor belt 3 and the top plate 8 is relatively large. In order to ensure the stability of the battery 4 during installation and disassembly, this solution provides a number of rollers 9 on the top plate 8. The rollers 9 reduce the friction between the top plate 8 and the conveyor belt 3 to ensure that the conveyor belt 3 can stably transport the battery 4, while ensuring the continuous support effect of the top plate 8 on the battery 4.

[0044] Preferably, a cover body 10 is provided at the opening of the bin body 1, and a cover plate 11 is extended from one side of the cover body 10 toward the battery accommodating cavity 2, so that when the battery 4 is placed on the conveyor belt 3, both sides of the battery 4 are positioned by the cover plate 11 and the conveyor belt 3 respectively.

[0045] Specifically, the interior of the battery accommodating chamber 2 is sealed and protected by the cover body 10. At the same time, due to the setting of the cover plate 11, when the battery 4 is placed in the groove on the upper surface of the conveyor belt 3, a limiting closed loop can be formed on the periphery of the battery 4 by the cover plate 11, the conveyor belt 3, and the rollers 5 on both sides, thereby improving the stability of the battery 4 during use.

[0046] The cover 10 and the bin body 1 can be connected by connecting members such as bolts.

[0047] Preferably, a side of the cover plate 11 close to the battery 4 has a limiting pad 12 , so that the limiting pad 12 provides a certain shock-absorbing effect on the side of the battery 4 .

[0048] The limiting pad 12 can be made of rubber material.

[0049] Preferably, a first power supply plate 13 is provided on the side of the battery 4 , a second power supply plate 14 is provided inside the battery accommodating cavity 2 , and the first power supply plate 13 matches the second power supply plate 14 .

[0050] Specifically, when the battery 4 is placed in the groove formed by the conveyor belt 3, the first power supply sheet 13 and the second power supply sheet 14 are overlapped, so that the battery 4 and the external circuit are powered to ensure the normal power supply function of the battery 4.

[0051] Preferably, the end of the cover plate 11 has a guide arc surface 15 .

[0052] Specifically, due to the setting of the guiding arc surface 15, when the cover plate 11 is inserted into the battery accommodating cavity 2, the guiding arc surface 15 can guide and press the side of the battery 4, thereby avoiding interference between the end of the cover plate 11 and the side of the battery 4 and causing damage to the side of the battery 4.

[0053] The present invention is not limited to the above-mentioned optimal implementation mode. Anyone can derive other forms of products under the inspiration of the present invention. However, no matter what changes are made in the shape or structure, any technical solution that is the same or similar to that of the present application falls within the scope of protection of the present invention.
