Description

Technical Field

[0001] The present invention relates to the technical field of power batteries, and in particular, to a power battery frame, a battery system, and an assembly method. Background Art

[0002] With the development of the automotive industry, more and more vehicles have entered the fields of production and life, playing a very important role in transportation and logistics. Among them, new energy vehicles use power batteries as the power source.

[0003] In the prior art, it is necessary to install the power battery into a frame to support and protect the power battery by using the frame. The frame is formed into an integrated structure by welding, and then the power battery is installed into the frame. When the power battery and the frame are assembled separately, since the frame has been assembled, it is impossible to use a lifting tooling to realize the downward installation of the power battery from top to bottom. It can only rely on manpower to push the power battery into the designated position of the frame from the side of the frame and then fix it. By using the above method, it is impossible to directly judge whether the installation of the power battery is in place, resulting in very low assembly efficiency. At the same time, during assembly, since the frame has been formed, if there are errors in the manufacture of the frame, it is easy to cause interference between the frame and the power battery, which not only easily causes damage to the power battery and the battery frame, but also has a high safety hazard. At the same time, the power battery is installed into the frame by manual side pushing, which results in a large labor intensity for workers and there is a risk that the power battery may fall and injure the workers.

[0004] Therefore, a power battery frame, a battery system, and an assembly method are needed to solve the above problems. Summary of the Invention

[0038] When assembling the power battery and the frame, in order to ensure the assembly efficiency, eliminate potential safety hazards, and ensure the smooth installation of the power battery, as Figure 1 - Figure 2 shown, the present invention provides a power battery frame. The power battery frame includes a plurality of mounting seat plates 1 and a plurality of support rods 3.

[0039] Among them, a plurality of mounting base plates 1 are arranged at intervals in the vertical direction, and adjacent mounting base plates 1 are parallel to each other. A plurality of support rods 3 are arranged between adjacent mounting base plates 1 along the length direction of the mounting base plates 1. One end of the support rod 3 is detachably connected to one of the adjacent mounting base plates 1, and the other end of the support rod 3 is detachably connected to the other of the adjacent mounting base plates 1. An installation space for installing the power battery 100 is formed between the support rod 3 and the adjacent mounting base plate 1.

[0040] In the above manner, there will be no interference phenomenon during the installation of the power battery 100, and the assembly process is convenient for observation. During the assembly process, a lifting device is used to directly lift and then lower the power battery 100 for installation, reducing the labor intensity of workers. After the power battery 100 is installed in place, the frame is assembled to prevent the power battery 100 from being knocked and damaged, eliminating potential safety hazards, and ensuring the assembly efficiency and the smooth installation of the power battery 100. Since the power battery frame is assembled and synthesized, if a problem occurs in one layer of the mounting base plate 1, it can be directly replaced, which is convenient for maintenance and ensures economy.

[0041] In some embodiments, the mounting base plate 1 includes a support base 11 and two connecting plates 12. The two connecting plates 12 are fixedly arranged on both sides of the support base 11 along the length direction of the support base 11. The support base 11 is used to support the power battery 100, and the support rod 3 is detachably connected to the connecting plate 12. Through the above settings, it is convenient for the support base 11 and the connecting plate 12 to be installed to form the mounting base plate 1. After the support base 11 or the connecting plate 12 is damaged, it can be directly replaced. In other embodiments, the support base 11 and the connecting plate 12 can also be designed as an integral structure, reducing the installation process and ensuring the structural strength of the mounting base plate 1. There is no further limitation here.

[0042] In some embodiments, a docking assembly 2 is arranged on the connecting plate 12. The docking assembly 2 includes a fixed part 21 and a docking part 22 which are connected to each other. The fixed part 21 is connected to the connecting plate 12, and the docking part 22 is connected to the support rod 3. By providing the fixed part 21, it is convenient to be fixedly installed with the connecting plate 12. By providing the docking part 22, it is convenient to be docked and installed with the support rod 3.

[0043] In some embodiments, a first installation hole is formed in the support rod 3, and a second installation hole is formed in the docking part 22. The first locking member is inserted through the first installation hole and the second installation hole to lock the relative positions between the docking part 22 and the support rod 3. In this embodiment, the first locking member is a positioning pin. By using the first locking member, the assembly of the support rod 3 and the abutting part can be quickly realized, thus ensuring the installation efficiency.

[0044] In some embodiments, a first connection hole is formed in the connection plate 12, and a second connection hole opposite to the first connection hole is formed in the support base 11. The second fastener is inserted through the first connection hole and the second connection hole. In this embodiment, the second fastener can be a bolt. Through the above arrangement, it is convenient to dock and install the connection plate 12 with the support base 11. When the second fastener passes through the first connection hole and the second connection hole and then a nut is installed, the installation of the connection plate 12 and the support base 11 can be achieved.

[0045] In some embodiments, the support rods 3 are arranged at equal intervals along the extending direction of the mounting seat plate 1. By arranging the support rods 3 at equal intervals, the force between adjacent mounting seat plates 1 can be ensured to be uniform, and stress concentration can be avoided.

[0046] In some embodiments, a positioning groove is formed in the mounting seat plate 1, and the power battery 100 can be embedded in the positioning groove. By providing the positioning groove for installing and positioning the power battery 100, it is convenient to quickly position the power battery 100 on the mounting seat plate 1, and the power battery 100 can be stably arranged on the mounting seat plate 1.

[0047] In some embodiments, buffer members are provided on both the wall surface and the bottom surface of the positioning groove. Specifically, the buffer members can be made of rubber or silica gel. By providing the buffer members, rigid contact between the power battery 100 and the mounting seat plate 1 can be avoided, thereby protecting the power battery 100. At the same time, when the power battery 100 is installed in the positioning groove, the buffer members are squeezed and deformed, thereby increasing the friction between the buffer members and the power battery 100, and further ensuring the stability of the relative position between the power battery 100 and the mounting seat plate 1.

[0048] This embodiment also provides a battery system, including a power battery 100 and the above-mentioned power battery frame, and the power battery 100 is installed in the power battery frame. By adopting the spliced power battery frame, the assembly efficiency can be ensured, potential safety hazards can be eliminated, and the smooth installation of the power battery 100 can be guaranteed.

[0049] This embodiment also provides an assembly method for installing the power battery 100 into the above-mentioned power battery frame, including the following steps:

[0050] S1. Horizontally place the mounting seat plate 1;

[0051] S2. Use a lifting device to lift the power battery 100, move it to the position of the mounting seat plate 1 and then lower it, and fix the power battery 100 on the mounting seat plate 1;

[0052] S3. Install the support rods 3 on the mounting seat plate 1 to form an assembled body;

[0053] S4. Assemble the assembled body vertically to form the main body of the battery system;

[0054] S5. Install the mounting seat plate 1 at the top on the main body of the battery system to complete the assembly. Through the above assembly method, the rapid assembly of the power battery 100 and the power battery frame can be realized, ensuring the assembly efficiency.

[0055] Obviously, the above embodiments of the present invention are only examples for clearly explaining the present invention, rather than limiting the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here.
