Abstract
Description
Technical Field
[0001] This utility model relates to the field of power battery technology, and in particular to a battery pack bracket and engineering machinery. Background Technology
[0002] Currently, with the promotion of new energy power, industrial vehicles, loaders, excavators, and other construction machinery are also choosing pure electric or hybrid power sources for their driving. For electrically driven construction machinery, a battery pack bracket is installed on the vehicle body to support and mount the battery pack. Since construction machinery often travels on construction sites with uneven and bumpy surfaces, the battery pack requires shock absorption measures.
[0003] In existing technologies, shock-absorbing pads are typically installed on the body of construction machinery, and the battery pack bracket is then placed on these pads. This installation method requires hoisting machinery to lift the battery pack, and then the suspended battery pack bracket is gradually lowered from top to bottom onto the shock-absorbing pads on the vehicle body. During this process, the position of the battery pack bracket is adjusted to ensure reliable positioning. This method requires frequent adjustments to the battery pack bracket's position to ensure proper positioning, making the operation quite difficult. Furthermore, lifting the battery pack bracket with hoisting machinery requires a large operating space; insufficient space will not meet the lifting requirements, limiting its use. In addition, due to the large size and heavy weight of the battery pack bracket on construction machinery, the safety hazards of working at height are also greater. Utility Model Content
[0004] The purpose of this utility model is to provide a battery pack bracket that has independent and reliable shock absorption performance, is easy to install, and is suitable for forklift loading. It can be used with forklifts to achieve low-altitude handling and lateral installation, with few installation restrictions, avoiding high-altitude hoisting operations and improving safety.

[0033] This embodiment provides a battery pack bracket. (Refer to...) Figures 1 to 2 As shown, the battery pack bracket includes a housing 1, a shock absorber 2, and a base 3. There are at least two housings 1, stacked one on top of the other. The shock absorber 2 is fixed to the base 3. The lowermost housing 1 is supported by the shock absorber 2, and the lowermost housing 1 and the base 3 form a space 301 for inserting forklift forks.
[0034] In this embodiment, at least two housings 1 of the battery pack bracket are stacked vertically, and each housing 1 can hold multiple battery packs. The shock absorber 2 is fixed to the base 3, and the lowermost housing 1 is supported by the shock absorber 2, thereby achieving the self-damping function of the battery pack bracket. This enables rapid installation of the battery pack bracket, eliminating the complex positioning process, and also avoids the need to add an additional shock absorber 2 to the vehicle body of the construction machinery, saving vehicle space and meeting the installation requirements of the battery pack bracket. Furthermore, the shock absorber 2 separates the base 3 from the housing 1, forming a gap space 301 between the lowermost housing 1 and the base 3. This gap space 301 provides sufficient forklift space for easy insertion of the forklift forks, facilitating forklift loading and enabling low-altitude transport and lateral installation of the battery pack bracket in conjunction with forklift operations. This reduces space limitations on installation operations, avoids high-altitude hoisting operations, and improves operational safety.
[0035] In this embodiment, the shock absorber 2 includes multiple shock absorber pads 21 spaced apart on the base 3. The lowest housing 1 is supported on the multiple shock absorber pads 21. The lowest housing 1, the shock absorber pads 21, and the base 3 are fixedly connected by a fastener 4. The space 301 includes multiple through-holes 302, which are formed by the lowest housing 1, the base 3, and two adjacent shock absorber pads 21. Specifically, in this embodiment, the forklift forks can extend into the through-holes 302, thereby facilitating forklift loading and low-altitude transport by the forklift.
[0036] In this embodiment, the number of shock-absorbing pads 21 is set to eight, with four shock-absorbing pads 21 on each side of the base 3.
[0037] Specifically, in this embodiment, the fixing component 4 includes a fixing bolt 41 and a fixing nut 42. The bottommost housing 1 has a first hole 111, the shock-absorbing pad 21 has a second hole 211, and the base 3 has a third hole 31. Specifically, the fixing bolt 41 passes through the first hole 111, the second hole 211, and the third hole 31 and is threadedly connected to the fixing nut 42, making the connection convenient and reliable.
[0038] This embodiment is not limited to this, and the fastener 4 may only include the fixing bolt 41. Specifically, the third hole 31 of the base 3 is a threaded hole. The fixing bolt 41 passes through the first hole 111 and the second hole 211 and is threadedly connected to the third hole 31, which can also realize a reliable connection between the housing 1, the shock absorber 2 and the base 3.
[0039] In this embodiment, the vibration damping pad 21 is made of rubber. Firstly, rubber has good elasticity, allowing it to deform rapidly and absorb energy when subjected to vibration and impact, effectively slowing down the transmission of vibration. Compared to some other rigid damping materials, the rubber damping component 2 can exert its damping effect over a wider frequency range, providing good damping for both low-frequency and high-frequency vibrations. Secondly, rubber has good damping properties, converting vibration energy into heat energy and dissipating it, reducing the repetitive effects of vibration. This allows the rubber damping component 2 to maintain stable damping performance during long-term use, reducing the likelihood of fatigue failure. Furthermore, the rubber damping component 2 has good adaptability and ease of installation. It can be processed into various shapes and sizes according to different damping requirements, easily installed on various equipment and structures, and has good compatibility with other components. In addition, the rubber damping component 2 has the advantage of relatively low cost. Compared to some high-performance damping materials, rubber is more competitive and can meet the damping needs of most ordinary industrial and civil applications.
[0040] In this embodiment, the housing 1 includes a bottom plate 11 and four side plates. The four side plates are arranged in a rectangular shape on the bottom plate 11. The bottom plate 11 at the bottom is supported on the shock absorber 2 and forms a gap 301 with the base 3. Specifically, when at least two housings 1 are stacked, the bottom plate 11 of the upper housing 1 is supported on the four side plates of the lower housing 1. Specifically, the bottom plate 11 of the upper housing 1 is fixedly connected to the four side plates of the lower housing 1 using fasteners such as screws and bolts.
[0041] Specifically, the side panel includes two first side panels 12 and two second side panels 13. The two first side panels 12 are spaced apart along a first direction. Each first side panel 12 includes a first side enclosure 121 and connecting portions 122 bent and disposed on opposite sides of the first side enclosure 121. The second side panels 13 are spaced apart along a second direction and located between the two first side panels 12. The opposite ends of the second side panels 13 are fixedly connected to the connecting portions 122 of the corresponding two first side panels 12. Specifically, the first connecting portions 122 bend and extend relative to the first side enclosure 121 in the first direction, and the opposite ends of the second side panels 13 are fixedly connected to the connecting portions 122 of the corresponding two first side panels 12, thereby enclosing the two first side panels 12 and the two second side panels 13 together to form a rectangular side panel frame structure. Optionally, the opposite ends of the second side panels 13 are fixed to the connecting portions 122 of the corresponding two first side panels 12 by welding.
[0042] Specifically, the second side plate 13 includes a second side enclosure 131 and a support portion 132. The second side enclosure 131 is spaced apart from the base 3. The two opposite ends of the second side enclosure 131 are fixedly connected to the connecting portions 122 of the two first side plates 12 on the corresponding sides. One end of the support portion 132 is fixedly connected to the base 3, and the other end is fixedly connected to the second side enclosure 131. Specifically, the second side enclosure 131 serves as the main body of the second side plate 13, participating in the formation of the main body of the rectangular side plate frame structure. The support portion 132 connects the base 3 and the second side enclosure 131, providing a fixed fulcrum for the second side enclosure 131 and ensuring the overall reliability and stability of the second side plate 13. Optionally, the two opposite ends of the second side enclosure 131 are welded to the connecting portions 122 of the two first side plates 12 on the corresponding sides, and one end of the support portion 132 is welded to the base 3, and the other end is welded to the second side enclosure 131.
[0043] In this embodiment, a first through hole 1211 is provided on the first side panel 121. The provision of the first through hole 1211 can reduce the overall weight of the first side panel 12, thereby achieving a lightweight improvement.
[0044] In this embodiment, a second through hole 112 is provided on the base plate 11. The provision of the second through hole 112 can reduce the overall weight of the base plate 11, thereby achieving a lightweight improvement.
[0045] This embodiment also provides an engineering machinery, which includes the aforementioned battery pack bracket and a vehicle body (not shown), with a base 3 fixed to the vehicle body. By installing the aforementioned battery pack bracket on the engineering machinery, the beneficial effects of the battery pack bracket can be achieved. Specifically, there is no need to add an additional shock absorber 2, saving vehicle body space and meeting the installation requirements of the battery pack bracket. The battery pack bracket allows for easy insertion of forklift forks, is suitable for forklift loading, and enables low-altitude handling and lateral installation in conjunction with forklift operations. Installation restrictions are minimal, avoiding high-altitude lifting operations and improving operational safety.
