Description

Technical Field

[0001] The utility model relates to the technical field of battery packs, and particularly to a battery pack installation and fixing structure and a battery pack. Background Art

[0002] The battery pack is an important component of the power battery system of new energy vehicles. It consists of multiple modules, each of which is composed of multiple battery cells and is managed by the battery management system (BMS).

[0003] At present, the reason why the installation point structure of the battery pack is integrated with the battery pack is due to the design of the entire vehicle. Once the installation point of the battery pack is damaged, the entire battery pack will be scrapped. In addition, most of the existing battery boxes can only install the battery pack from the height direction of the battery pack, which limits the assembly method of the battery pack, and the small space inside the vehicle makes the assembly of the battery pack inconvenient. Utility Model Content

[0004] In view of the above-mentioned technical problems existing in the prior art, a battery pack installation and fixing structure and a battery pack are provided. When the installation site is damaged, the installation frame or the inner mounting block can be replaced separately, thereby effectively reducing the replacement cost of the battery pack; and the battery pack can be assembled from the side outside the vehicle, which makes the installation of the battery pack more convenient and improves the assembly efficiency.

[0005] The purpose and effect of the utility model are achieved by the following specific technical means:

[0006] A battery pack installation and fixing structure, comprising:

[0007] Install the frame;

[0008] External mounting blocks, which are provided in plurality and are formed in one piece laterally on one side of the mounting frame, and each of the external mounting blocks has an assembly cavity on its inner side;

[0009] The inner mounting block is provided with a plurality of assembling cavities which are detachably connected to the plurality of outer mounting blocks.

[0010] Optionally, the outer wall of the outer mounting block is provided with a plurality of whole vehicle profile mounting holes, and the inner mounting block is provided with a plurality of whole vehicle threaded fixing holes respectively corresponding to the plurality of whole vehicle profile mounting holes.

[0011] Optionally, the inner mounting block is provided with a screw fixing hole corresponding to the screw limiting hole, the outer mounting block is provided with a screw limiting hole, a screw is inserted into the screw limiting hole, and the inner end of the screw is threadedly connected to the screw fixing hole.

[0012] Optionally, the outer end of the screw has a step portion that matches the screw limiting hole.

[0013] The utility model also provides a battery pack, comprising the above-mentioned battery pack installation and fixing structure and a battery pack main body, wherein the battery pack main body is installed in a mounting frame.

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

[0015] The present application provides a number of external mounting blocks and internal mounting blocks, which makes it convenient for workers to install the battery pack on the whole vehicle and can ensure the stability after installation, or facilitates the removal of the battery pack from the whole vehicle. Since the battery pack body and the mounting frame, the internal mounting blocks and the external mounting blocks are all connected in a detachable manner, the mounting frame or the internal mounting blocks can be replaced separately when the mounting site is damaged, which effectively reduces the replacement cost of the battery pack; and the battery pack can be assembled from the side outside the vehicle, which makes it easier to install the battery pack and improves assembly efficiency.

[0023] See also Figure 1-6 , the embodiments of the utility model are further described;

[0024] A battery pack installation and fixing structure, comprising:

[0025] Install frame 2;

[0026] External mounting blocks 3, which are provided with a plurality of external mounting blocks 3 and are formed in one piece laterally on one side of the mounting frame 2, and each external mounting block 3 has an assembly cavity on its inner side;

[0027] The inner mounting block 4 is provided with a plurality of assembly cavities which are detachably connected to the plurality of outer mounting blocks 3 .

[0028] Specifically, the mounting frame 2 and the outer mounting block 3 are made by a profile extrusion process, and the battery pack body is detachably connected to the mounting frame 2. When the mounting and fixing structure is assembled with the whole vehicle, the inner mounting block 4 is first installed in the assembly cavity on the outer mounting block 3, and then the outer mounting block 3 and the inner mounting block 4 are installed on the whole vehicle with bolts, and the assembly direction is the length or width direction of the battery pack.

[0029] The present application provides a plurality of external mounting blocks 3 and internal mounting blocks 4, so as to facilitate the staff to install the battery pack on the whole vehicle and ensure the stability after installation, or to facilitate the removal of the battery pack from the whole vehicle. Since the battery pack body and the mounting frame 2, the internal mounting block 4 and the external mounting block 3 are all connected in a detachable manner, the mounting frame 2 or the internal mounting block 4 can be replaced separately when the mounting site is damaged, which effectively reduces the replacement cost of the battery pack; and the battery pack can be assembled from the side outside the vehicle, which is more convenient for the installation of the battery pack and improves the assembly efficiency.

[0030] The outer wall of the outer mounting block 3 is provided with a plurality of vehicle body mounting holes 32 , and the inner mounting block 4 is provided with a plurality of vehicle body threaded fixing holes 42 corresponding to the plurality of vehicle body mounting holes 32 .

[0031] Specifically, in order to position the mounting and fixing structure on the vehicle, bolts are inserted into the vehicle. The bolts are first passed through the mounting holes 32 of the vehicle body and then threaded into the threaded fixing holes 42 of the vehicle, thereby positioning the mounting and fixing structure on the vehicle.

[0032] The inner mounting block 4 is provided with a screw fixing hole 41 corresponding to the screw limiting hole 31 , and the outer mounting block 3 is provided with a screw limiting hole 31 , in which a screw 33 is inserted, and the inner end of the screw 33 is threadedly connected to the screw fixing hole 41 .

[0033] Specifically, in order to strengthen the firmness between the inner mounting block 4 and the outer mounting block 3, the screw 33 is inserted into the screw limiting hole 31, and then the screw 33 is threadedly connected in the screw fixing hole 41. After the screw 33 is installed, its outer end is limited in the screw limiting hole 31. At this time, several whole vehicle profile mounting holes 32 on the outer mounting block 3 are aligned with several whole vehicle threaded fixing holes 42 on the inner mounting block 4, which is convenient for the staff to install the bolts between the whole vehicle profile mounting holes 32 and the inside of the whole vehicle threaded fixing holes 42.

[0034] The outer end of the screw 33 has a step portion 331 that matches the screw limiting hole 31 . This design is conducive to the stable connection between the inner mounting block 4 and the outer mounting block 3 .

[0035] The utility model further provides a battery pack, comprising the above-mentioned battery pack installation and fixing structure and a battery pack main body 1 , wherein the battery pack main body 1 is installed in a mounting frame 2 .

[0036] Specifically, the present application provides a plurality of external mounting blocks 3 and internal mounting blocks 4, which makes it convenient for the staff to install the battery pack on the whole vehicle and ensures the stability after installation, or facilitates the removal of the battery pack from the whole vehicle. Since the battery pack body and the mounting frame 2, the internal mounting block 4 and the external mounting block 3 are all connected in a detachable manner, the mounting frame 2 or the internal mounting block 4 can be replaced separately when the mounting site is damaged, which effectively reduces the replacement cost of the battery pack; and the battery pack can be assembled from the side outside the vehicle, which makes it easier to install the battery pack and improves the assembly efficiency.
