[0002] The statements in this section are merely to provide background information related to the disclosure of this utility model and do not necessarily constitute prior art.

[0003] In the field of battery packs for elevators, electric vehicles, or engineering vehicles, counterweights are typically installed within the battery pack to meet the overall balance requirements of the elevator or vehicle. Therefore, the specific design of the battery pack requires a reasonable layout and configuration of the counterweights, battery components, battery circuit boards, and other devices to meet the installation, maintenance, and usage needs.

[0004] During the production of battery packs, the installation of battery components and their corresponding battery circuit boards requires a high degree of stability for the entire pack. Therefore, the requirements for the balance of the counterweight and the stability of the installation are also high. As a result, existing battery packs require on-site adjustment of the balance of the counterweight, battery components, battery circuit boards, etc. during assembly, making the overall installation and process complex. Utility Model Content

[0005] To overcome the shortcomings of the prior art, this utility model provides a battery pack with a counterweight that is directly set at the bottom of the open-type housing of the battery pack and then assembled with the battery components into an integrated installation. This structure enables the battery pack to be quickly installed, transported and used stably.

[0006] The technical solution adopted by this utility model is as follows: an integrated battery pack with counterweight, including an open shell, a counterweight device, and a cover plate. The battery pack also includes a counterweight base plate and an inner protective plate. The counterweight base plate is located on top of the counterweight device, and the top of the counterweight base plate is used to place the battery assembly. The inner protective plate has a stepped structure and is fastened to the inner wall of the open shell, forming a rainproof structure on the top of the open shell. The top of the rainproof structure is sealed to the cover plate by a sealing element. At the same time, an electrical board step is formed at the part lower than the rainproof structure, and the electrical board step provides support for the battery circuit board.

[0012] In at least some embodiments, an observation port is also provided between the cover plate and the rainproof structure.

[0013] The open-type shell has a hollow counterweight cavity, and a counterweight block is placed in the hollow counterweight cavity.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] 1. The counterweight device is sealed at the bottom of the open shell, and then a counterweight base plate is installed on it to seal it, so that the device is stably set at the bottom of the battery pack, forming a stable prefabricated structure. There is no need to adjust the position during later installation, which reduces the number of processes and shortens the construction period. Moreover, the counterweight and the open shell can be processed externally, and then the battery pack that meets the requirements can be assembled in the assembly workshop.

[0016] 2. A counterweight base plate is used to cover the counterweight device at the bottom of the open-type housing, and a stepped inner protective plate is provided on the side of the open-type housing.

[0026] like Figure 1 As shown, an integrated battery pack with counterweight includes an open-type shell 1, a counterweight device 10, and a cover plate 7. The battery pack also includes a counterweight base plate 2 and an inner protective plate 3. The counterweight base plate 2 is positioned on top of the counterweight device 10, and the top of the counterweight base plate 2 is used to place the battery assembly 11. The inner protective plate 3 has a stepped structure, is fastened to the inner wall of the open-type shell 1, and forms a rainproof structure 6 on the top of the open-type shell 1. The top of the rainproof structure 6 is sealed to the cover plate 7 by a sealing element 12. Simultaneously, an electrical board step 4 is formed below the rainproof structure 6, providing support for the battery circuit board 5, allowing for easy movement of the battery circuit board 5 on the electrical board step 4, thereby facilitating observation of the internal battery assembly 11. In summary, the integrated battery pack of this utility model, from... Figure 1As can be seen from the embodiments, a counterweight base plate 2 is used to cover the counterweight device 10 at the bottom of the open-type housing 1, and a stepped inner protective plate 3 is provided on the side of the open-type housing 1. A rainproof structure 6 is formed on the top of the inner protective plate 3 to achieve sealing and rain protection. An electrical plate step 4 is formed at the part below the rainproof structure 6 to facilitate the placement, installation, maintenance and observation of the battery assembly 11.

[0027] In at least some embodiments, from Figure 1 It can also be seen that several positioning posts 9 are fixed on the top of the counterweight base plate 2.
