[0036] As described in the background art, when replacing the battery of an electric forklift, it is usually necessary to manually dismantle the battery assembly to replace the battery. The disassembly and assembly structure of the traditional battery is relatively inconvenient, which usually takes a lot of time and wastes a lot of manpower and material resources.

[0037] In order to solve this technical problem, the utility model provides a battery installation structure, which is applied to power an electric forklift.

[0038] Specifically, please refer to Figure 1-Figure 3 , the battery installation structure specifically includes:

[0039] The battery assembly 2 is arranged at the inner side of the lower end of the frame 1. The lower end of the frame 1 is provided with a receiving cavity 3.

[0042] The battery installation structure provided by the utility model makes it more convenient and quick to replace the battery of the electric forklift through the coordinated design of multiple structures. The battery assembly 2 can be directly placed in the accommodating cavity 3 opened at the lower end of the frame 1 through another forklift or other conveying and lifting equipment, and the installed battery assembly 2 can be limited by the limiting assembly 13, so as to complete the battery replacement of the electric forklift; the overall structure is relatively simple, the operation is convenient, and the time required for battery replacement is reduced.

[0043] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0044] Embodiment 1:

[0045] Please refer to Figure 1-Figure 5 , a battery mounting structure, comprising:

[0046] The battery assembly 2 is arranged at the inner side of the lower end of the frame 1. A accommodating cavity 3 is opened at the lower end of the frame 1. The battery assembly 2 is located inside the accommodating cavity 3. Both sides of the lower end of the accommodating cavity 3 are fixed with pallets. The two ends of the battery assembly 2 are located above the two pallets. The battery assembly 2 can be directly delivered from the side of the frame 1 into the accommodating cavity 3 by another forklift or other conveying and lifting equipment.

[0047] Specifically, the battery assembly 2 includes a fixing frame 4 and a battery pack 5, and the battery pack 5 is placed on the inner side and the upper end of the fixing frame 4; further, the fixing frame 4 includes a bottom plate 6 and a top plate 7, and support rods 8 are vertically arranged between the bottom plate 6 and the top plate 7 and at the four end corner positions, and the upper and lower ends of the support rods 8 are detachably fixed to the bottom plate 6 and the top plate 7 by screws, and limiting components 13 are arranged at the two end corner positions of the front end of the bottom plate 6, and the bottom plate 6 is detachably connected to the support plates on both sides of the lower end of the accommodating cavity 3 through the limiting components 13.

[0048] It can be known that the two battery packs 5 can be fixed by the fixing frame 4, and after the fixing frame 4 carries the battery pack 5 and is placed inside the accommodating cavity 3, it can be connected to the support plate through the two limiting components 13 at the front end of the bottom plate 6, thereby realizing the movement limit of the battery assembly 2 and then completing the installation of the battery assembly 2; when the battery assembly 2 needs to be replaced, the limiting component 13 is removed to release the movement limit of the battery assembly 2, and then the battery assembly 2 can be taken out from the accommodating cavity 3.

[0049] Embodiment 2:

[0050] The battery installation structure provided in Example 1 is further optimized. Specifically, Figure 6-Figure 7 As shown, the limiting assembly 13 includes a latch 14 and a limiting seat 16. A limiting ring 15 is sleeved on the outer side of the latch 14. The lower end of the latch 14 is snap-fitted with the limiting seat 16. The latch 14 and the bottom plate 6, as well as the latch 14 and the support plate are all plug-in connected.

[0051] Furthermore, a movable block 17 is embedded on one side of the limit seat 16, one end of the movable block 17 is rotatably connected to the limit seat 16 through a rotating shaft 18, and a pinching plate 20 is fixed to the other end of the movable block 17, which facilitates the flipping and rotation of the movable block 17, and a button ring 19 is sleeved on the outside of the rotating shaft 18, one end of the button ring 19 is fixedly connected to the movable block 17, and the other end of the button ring 19 is fixedly connected to the limit seat 16, a buckle frame 21 is fixed to the inner side of the movable block 17, a buckle groove 22 is provided on the outer side of the lower end of the latch 14, and the buckle frame 21 is buckled and connected with the buckle groove 22.

[0052] Through the above structural design, after the fixing frame 4 carrying the battery pack 5 is placed inside the accommodating cavity 3, the latch 14 carrying the limiting ring 15 is inserted from the upper end of the bottom plate 6, so that the lower end of the latch 14 passes through the bottom plate 6 and the support plate, and extends to the position below the support plate, and then the movement of the latch 14 is limited by installing the limiting seat 16, and then the movement of the bottom plate 6 is limited by the latch 14, thereby completing the movement of the battery assembly 2.

[0053] When the limit seat 16 is installed, the movable block 17 is flipped outward to make the buckle frame 21 move out from the inner side of the limit seat 16. At the same time, the button ring 19 accumulates force through the flipping of the movable block 17 to keep the movable block 17 flipped outward until the limit seat 16 is sleeved with the lower end of the pin 14. Then the movable block 17 is released and the stored force is released by the button ring 19 to drive the movable block 17 to flip and reset. The reset movable block 17 is buckled with the buckle groove 22 through the buckle frame 21, thereby completing the connection limit between the limit seat 16 and the pin 14, so that the pin 14 cannot be pulled out upward, ensuring that the battery assembly 2 cannot move.

[0054] Embodiment 3:

[0055] The battery installation structure provided in Example 1 is further optimized. Specifically, Figure 3-Figure 5 As shown, support frames 10 are provided between the bottom plate 6 and the top plate 7 and at positions on both sides. The middle part of the upper end of the support frame 10 is detachably fixed to the top plate 7 by screws, and the lower parts of both ends of the support frame 10 are detachably fixed to the bottom plate 6 by screws; a plurality of groups of reinforcing plate groups are provided between the bottom plate 6 and the top plate 7 and at positions at the rear end, each group of reinforcing plate groups includes two plate bodies 11, and the two plate bodies 11 in each group of reinforcing plate groups are arranged in an eight-shaped shape, and the upper ends of the plate bodies 11 are detachably fixed to the top plate 7 by screws, and the lower ends of the plate bodies 11 are detachably fixed to the bottom plate 6 by screws.

[0056] Among them, in order to achieve the positioning and placement of the battery pack 5, the lower ends of the bottom plate 6 and the top plate 7 are both threadedly connected with positioning bolts 9, and the battery pack 5 is plugged into the positioning bolts 9. Through the plugging of the battery pack 5 and the positioning bolts 9, the battery pack 5 can be limited in horizontal movement after being placed, thereby preventing the battery pack 5 from sliding.

[0057] Furthermore, a buffer pad 12 is detachably fixed at the rear end of the top plate 7 by screws. The buffer pad 12 is made of rubber. When the battery assembly 2 is placed into the accommodating cavity 3 through the device, the buffer pad 12 can contact the inner wall of the accommodating cavity 3, thereby preventing the top plate 7 or the bottom plate 6 from directly colliding with the accommodating cavity 3, thereby reducing the damage to the battery pack 5 caused by the impact of the collision during installation.

[0058] Embodiment 4:

[0059] The battery installation structure provided in Example 1 is further optimized. Specifically, Figure 8-Figure 9 As shown, it also includes a battery heating mechanism for heating the liquid in the battery. The battery heating mechanism includes a circulation pipe, a liquid pump, and a battery water heater. The battery pack 5 is connected to the liquid pump and the battery water heater through the circulation pipe. There are two ways to connect the two battery packs 5, such as Figure 8 As shown, two battery assemblies are connected in parallel through a circulation tube; Fig. 9The two battery assemblies are connected in series through a circulation pipeline. In order to facilitate real-time monitoring of the battery liquid, temperature and pressure integrated sensors are provided on the circulation pipe and at the front and rear ends of the battery water heater.

[0060] It can be seen that by starting the liquid pump, the heat-conducting medium (battery liquid) in the battery pack 5 can be circulated in the circulation pipe, and by starting the battery water heater, the circulating heat-conducting medium (battery liquid) can be heated, thereby ensuring that the forklift can charge and discharge normally in a low-temperature environment, avoiding a significant impact on the performance of the entire vehicle, reducing charging time, reducing standby time, and improving work efficiency.
