Description

Technical Field

[0001] The utility model belongs to the technical field of electric loaders and relates to an electric loader power battery arrangement assembly and an electric loader. Background Art

[0002] As an important piece of construction machinery, loaders are primarily used for operations such as shoveling and loading materials, greatly improving loading and unloading efficiency. With the rapid development of new energy construction machinery, electric loaders are gradually replacing traditional loaders and are being used in various construction fields, especially on-site construction. Electric loaders offer advantages such as low energy consumption, high environmental friendliness, low failure rate, and low maintenance costs, and have broad application prospects.

[0003] Compared with traditional fuel loaders, electric loaders use the electricity stored in the battery pack as their power source. The number of battery packs they carry determines the endurance of the electric loader. At present, electric loaders generally adopt the solution of rear-mounted battery frame, that is, the battery frame is installed at the tail of the rear frame in order to carry more battery packs. However, the existing battery layout scheme still has many disadvantages: the utilization rate of the rear frame space is low, resulting in a significant limitation on the number of battery packs that can be carried. When the number of battery packs needs to be increased, the rear size of the rear frame is often widened or lengthened to increase the space. This results in a larger overall size of the vehicle, which is not conducive to the compact design of the vehicle and also makes the appearance of the vehicle bloated and uncoordinated. Furthermore, the excessive weight of the rear frame has a greater impact on the center of gravity of the vehicle, which is not conducive to the stability of the vehicle. In addition, the rear-mounted battery means that the cooling system can only be installed in the middle of the vehicle body, which is not conducive to heat dissipation. Utility Model Content

[0038] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in this field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by this utility model.

[0039] Example:

[0040] like Figures 1 to 8 As shown, the electric loader power battery layout assembly of this embodiment includes a rear frame 1, a mounting platform 2, an upper middle battery frame 31, a lower middle battery frame 32, an upper rear battery frame 41, a lower rear battery frame 42 and a battery pack 5.

[0041] A mounting platform 2 is welded to the rear middle portion of the upper end of the rear frame 1 , and a hollow structure 11 is provided below the mounting platform 2 .

[0042] Four layers of upper-middle battery frames 31 are assembled longitudinally in the middle front position of the installation platform 2, and two battery packs 5 are assembled inside each layer of upper-middle battery frame 31. A layer of lower-middle battery frame 32 is assembled longitudinally at the lower end of the upper-middle battery frame 31, and a battery pack 5 is assembled inside the lower-middle battery frame 32. The lower-middle battery frame 32 is located in the internal space of the hollow structure 11.

[0043] An upper rear battery frame 41 is assembled longitudinally at the middle rear position of the mounting platform 2, and a battery pack 5 is assembled inside the upper rear battery frame 41. Two lower rear battery frames 42 are assembled longitudinally at the lower end of the upper rear battery frame 41, and a battery pack 5 is assembled inside each layer of the lower rear battery frame 42. The lower rear battery frame 42 is located in the internal space of the hollow structure 11.

[0044] The battery pack 5 is assembled inside the upper middle battery frame 31 , the lower middle battery frame 32 , the upper rear battery frame 41 and the lower rear battery frame 42 by bolts.

[0045] In this way, without substantially changing the overall dimensions of the vehicle, the middle battery frames (upper middle battery frame 31 and lower middle battery frame 32) and rear battery frames (upper rear battery frame 41 and lower rear battery frame 42) are sequentially arranged along the lateral direction of the rear frame 1, while the upper middle battery frame 31 and lower middle battery frame 32 are arranged along the longitudinal direction of the rear frame 1. This fully utilizes the lateral and longitudinal space of the rear frame 1, allowing for the installation of more battery packs 5 on the rear frame 1, thereby improving the vehicle's endurance. The lower middle battery frame 32 and lower rear battery frame 42 are lowered into the interior space of the rear frame 1 to lower the center of gravity of the vehicle, contributing to overall vehicle stability.

[0046] The edge of the bottom-most upper-middle battery frame 31 is connected to the middle edge of the upper end of the rear frame 1 via several shock absorbers 6. The edge of the upper rear battery frame 41 is connected to the rearward edge of the upper end of the rear frame 1 via shock absorbers 6. Specifically, the edges of the upper-middle battery frame 31 and the upper rear battery frame 41 extend outward to form a flange 7, which has a first mounting hole. The edge of the rear frame 1 has a second mounting hole. The ends of the shock absorbers 6 are respectively connected to the first and second mounting holes. This reduces the transmission of vibration from the rear frame 1 to the battery frame, thereby extending the service life of the battery pack 5.

[0047] A first space 81 for mounting the cab is located at the front end of the rear frame 1. A second space 82 for mounting the rear axle is located below the center of the rear frame 1. The upper and lower middle battery frames 31, 32 are located behind the first space 81 and above the second space 82. This allows the vehicle to accommodate a larger number of battery packs 5 while maintaining a smaller and more compact design.

[0048] A heat sink base 91 is mounted on the upper end of the upper rear battery frame 41. A radiator is mounted on this base. An electrical assembly rack 92 is mounted on this base. This rack is a frame structure and is used to mount electrical equipment. The radiator and electrical equipment are mounted on the rear end of the rear frame 1, which further improves heat dissipation for the entire vehicle.

[0049] An electric loader is provided with the electric loader power battery arrangement assembly described above in this embodiment.

[0050] So far, this embodiment has been described in detail with reference to the accompanying drawings. Based on the above description, those skilled in the art should have a clear understanding of the electric loader power battery arrangement assembly and the electric loader of the present invention. Of course, the above is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. All equivalent structural transformations made by using the contents of the present invention specification and drawings under the utility model concept of the present invention, or direct / indirect application in other related technical fields are included in the patent protection scope of the present invention and should be protected by the present invention.
