Description

Technical Field

[0001] This utility model relates to the field of battery pack technology, specifically a battery pack for engineering machinery. Background Technology

[0002] New energy forklifts are a type of construction machinery. New energy forklifts refer to forklifts that use non-traditional fuels (such as electricity, hydrogen, etc.) as their power source. Compared with traditional internal combustion forklifts (diesel, liquefied gas, etc.), the battery pack of new energy forklifts is the core power source of electric forklifts, and its performance directly affects the forklift's range, efficiency and operating costs.

[0003] The existing battery packs have the following problems: Currently, battery packs are installed directly into the forklift's battery compartment. To facilitate installation, the battery compartment is larger than the battery pack. While this makes installation easier, the battery pack has poor stability after installation. Even with bolts for fastening, the battery pack may shift under prolonged vibration, leading to problems such as bolt jamming and breakage. Utility Model Content

[0004] The purpose of this invention is to provide a battery pack for engineering machinery to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a battery pack for engineering machinery, comprising a main body, a wiring panel on the main body, a mounting base at the bottom of the main body, the mounting base comprising a base, a mating interface on the base, bolt holes on the base, a pad at the bottom of the main body, and a mating block at the bottom of the pad.

[0006] Preferably, the base has a recess, and the bottom of the pad has a protrusion.

[0007] Preferably, the surface of the bump is provided with a pad.

[0008] Preferably, the base is provided with a positioning frame.

[0009] Preferably, the upper end of the positioning frame is an inclined surface.

[0010] Preferably, the depth of the mating interface is greater than the height of the mating block, and when the pad is placed on the surface of the base, the bottom surface of the mating block does not contact the bottom surface of the mating interface.

[0011] Preferably, the pad is placed on the surface of the base, the protrusion is inserted into the recess, and the pad is under compression.

[0012] Compared with the prior art, the beneficial effects of this utility model are: When installing the main body, first place the base in the battery compartment of the new energy forklift, then connect the battery compartment and bolt holes with bolts to fix the base inside the battery compartment. Next, the outer surface of the base will abut against the inner surface of the battery compartment, and the pad will be fixed to the bottom of the main body. Place the main body into the battery compartment. After the main body is completely placed inside the battery compartment, the pad will be placed on the base, and the mating block will be inserted into the mating interface. After the mating is completed, the pad will be locked in place, effectively suppressing unstable shaking of the main body during vibration, thus completing the positioning of the main body and ensuring high stability after installation. After suppressing vibration of the main body, the main body fixed by bolts is not easy to cause bolt misalignment due to vibration, resulting in problems such as bolt jamming and breakage under stress.

[0014] In the diagram: Main body-1, Wiring panel-2, Mounting base-3, Base-31, Connecting interface-32, Bolt hole-33, Pad-34, Connecting block-35, Notch-36, Protrusion-37, Pad layer-38, Positioning frame-39. Detailed Implementation

[0015] To further explain the technical solution of this utility model, a detailed description is provided below through specific embodiments.

[0016] Please see Figure 1 and Figure 2 This utility model provides a battery pack for engineering machinery, including a main body 1, a battery pack for the main body 1, a wiring panel 2 on the main body 1, and a mounting base 3 at the bottom of the main body 1.

[0017] Please see Figure 3 and Figure 4 This utility model provides a battery pack for engineering machinery. The mounting base 3 includes a base 31. The left and right ends of the base 31 are integrally formed with interface 32, and the base 31 is provided with bolt holes 33.

[0018] The bottom of the main body 1 is fixed with a pad 34 by bolts. Both ends of the lower end face of the pad 34 are integrally formed with mating blocks 35. The depth of the mating interface 32 is greater than the height of the mating block 35.

[0019] The base 31 has a notch 36 in the middle, and the pad 34 has a protrusion 37 integrally formed in the middle of the lower end face. The surface of the protrusion 37 is provided with a pad 38, which is elastic.

[0020] The base 31 is provided with a positioning frame 39, the upper end of which is inclined, which facilitates docking.

[0021] When the pad 34 is placed on the surface of the base 31, the bottom surface of the mating block 35 does not contact the bottom surface of the mating interface 32, so that the base 31 directly supports the pad 34 and the main body 1, thereby improving the support capacity. When the pad 34 is placed on the surface of the base 31, the protrusion 37 is inserted into the recess 36, and the pad layer 38 is in a state of compression. The compressed pad 34 has a certain shock absorption effect.

[0022] Specifically, when installing the main body 1, the base 31 is first placed in the battery compartment of the new energy forklift. Then, the battery compartment and bolt holes 33 are connected by bolts to fix the base 31 inside the battery compartment. Next, the outer surface of the base 31 will abut against the inner surface of the battery compartment. The pad 34 is fixed to the bottom of the main body 1 by bolts. The main body 1 is lifted and placed into the battery compartment. Then, under the guidance of the positioning frame 39, the pad 34 will align with the base 31. After the main body 1 is completely placed inside the battery compartment, the pad 34 will be placed on the base 31, and the protrusion 37 will be inserted into the recess 36. At the same time, the docking block 35 will be inserted into the docking interface 32. After docking, the pad 34 will be locked in place, effectively suppressing the unstable shaking of the main body 1 during vibration, thus completing the positioning of the main body 1 and ensuring high stability after installation. After suppressing the vibration of the main body 1, the main body 1 fixed by bolts is not easy to cause bolt misalignment due to vibration, resulting in problems such as bolt jamming and breakage under stress.

[0023] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
