[0027] The technical solution provided by the embodiments of the present application is described below in conjunction with the accompanying drawings.

[0028] like Figure 1 - Fig.10 As shown, the present application provides a battery module insulating bracket assembly, including a main bracket 1, two detachable side panels 2 are symmetrically installed on one side of the main bracket 1, and a detachable insulating protective plate 3 is commonly installed on one end of the two side panels 2 away from the main bracket 1, an upper pressing plate 4 and a lower pressing plate 8 are respectively arranged on the top and bottom of the two side panels 2 away from the main bracket 1, and an adjustment mechanism 6 is arranged on one side of the two side panels 2. The main bracket 1, the insulating protective plate 3 and the two side panels 2 are enclosed to form an insulating bracket with an inner cavity. Specifically, an insulating film is arranged on the inner wall of the main bracket 1 to prevent the power supply of the battery module from being connected to the main bracket 1 and causing safety hazards The two side panels 2 are fixedly connected to the main bracket 1 by bolts, which is convenient for disassembly and assembly between the side panels 2 and the main bracket 1, and the two side panels 2 are provided with heat dissipation holes, which is convenient for heat dissipation of the battery module when working. The inner cavity of the insulating bracket is used to install the battery module, and the insulating protective plate 3 is provided with slots for the positive and negative electrodes of the battery module to pass through, and the insulating protective plate 3 is also provided with notches on both sides. One side of the two side panels 2 is provided with a convex block. When installing between the insulating protective plate 3 and the side panel 2, the convex block can be inserted into the notch to quickly position the insulating protective plate 3 and the side panel 2, which is convenient for installation between the insulating protective plate 3 and the side panel 2;

[0029] The adjusting mechanism 6 includes an adjusting component for driving the upper pressure plate 4 and the lower pressure plate 8 to rise and fall synchronously. The adjusting component includes a concave cavity formed on the outer side of the side plate 2 and a bidirectional threaded rod 61 rotatably installed in the concave cavity. Two moving blocks 62 are sleeved on the bidirectional threaded rod 61, and one end of the two moving blocks 62 is fixed with a connecting block 63. The two connecting blocks 63 are respectively installed with a rotatable connecting rod 65 on the opposite sides. The upper pressure plate 4 and the lower pressure plate 8 are respectively detachably installed on the opposite ends of the two connecting rods 65. Specifically, a rotating cavity is opened in the connecting block 63, a rotating block is installed at one end of the connecting rod 65, and the rotating block is in the rotating cavity, which is conducive to the rotation of the connecting rod 65.

[0030] Furthermore, a threaded connection portion 66 is formed at the opposite ends of the two connecting rods 65, and through holes for the threaded connection portion 66 to pass through are formed at the top and bottom of the side plate 2. A threaded connection hole 42 matching with the threaded connection portion 66 is formed on the opposite sides of the upper pressure plate 4 and the lower pressure plate 8. Specifically, the diameter of the through hole is larger than the diameter of the threaded connection portion 66, and the threaded connection portion 66 can pass through the through hole.

[0031] First, assemble. During the assembly process, insert one end of the two side plates 2 into the two ends of one side of the main bracket 1 respectively, and fix the two side plates 2 and the main bracket 1 by bolts. Then, install the upper pressing plate 4 and the lower pressing plate 8 on the opposite ends of the two connecting rods 65 through the screw connection part 66 and the screw connection hole 42, and install the reinforcement plate 5 on the upper and lower sides of the two side plates 2 by bolts to reinforce the two side plates 2. Then, install the insulation protection plate 3 on the end of the two side plates 2 away from the main bracket 1 by bolts, thereby completing the assembly of the insulation bracket;

[0032] Specifically, when in use, the insulating protective plate 3 is disassembled from the two side plates 2, and the bidirectional threaded rod 61 is rotated so that the two moving blocks 62 move away from each other along the bidirectional threaded rod 61, and the upper pressing plate 4 and the lower pressing plate 8 are driven away from the side plates 2 through the connecting block 63 and the connecting rod 65, and then the battery module is assembled into the inner cavity of the insulating bracket, and then the bidirectional threaded rod 61 is rotated in the opposite direction through the adjusting disk 64, so that the two moving blocks 62 move closer to each other along the bidirectional threaded rod 61, and the upper pressing plate 4 and the lower pressing plate 8 are driven away from the side plates 2 through the connecting block 63 and the connecting rod 65. The plate 4 and the lower pressure plate 8 are close to the side plate 2 until they collide with each other, so as to confine the battery module in the inner cavity of the insulating bracket. At the same time, the partition 41 on the upper pressure plate 4 and the lower pressure plate 8 blocks the front end of the battery module. Then, the insulating protection plate 3 is installed on one end of the two side plates 2 by bolts to seal the front end of the battery module to complete the installation of the battery module. There is no need to use tools to remove the upper pressure plate 4 and the lower pressure plate 8 from the side plate 2 and then install the battery module, which is conducive to the rapid installation of the battery module.

[0033] Further, refer to Figure 1-Figure 3 As shown, an adjusting disk 64 is installed in the middle of the bidirectional threaded rod 61, and a plurality of convex teeth distributed in a ring array are installed on the outer circumference of the adjusting disk 64. Specifically, the convex teeth are rectangular, and tooth grooves are formed between two adjacent convex teeth, which is beneficial to increase the friction force of the outer circumference of the adjusting disk 64 and facilitate the user to rotate the adjusting disk 64.

[0034] Continue to refer Figure 1-Figure 3 as well as Figure 5-Figure 9As shown, the adjustment mechanism 6 also includes a locking assembly 7 for locking the adjustment member to a limited position, and the locking assembly 7 includes a mounting block 71 mounted on one side of the inner wall of the concave cavity and a mounting cavity 79 formed inside the mounting block 71, a locking plate 72 is provided on one side of the mounting block 71, and a locking tooth engaged with the convex tooth is formed on one side of the locking plate 72, an elastic assembly is built in the mounting cavity 79, and the elastic assembly is used to drive the locking tooth to move and reset, and an opening communicating with the mounting cavity 79 is opened on one side of the mounting block 71, which is conducive to the locking plate 72 being moved out of the mounting cavity 79 to lock the adjustment disk 64 to a limited position, or the locking plate 72 being retracted into the mounting cavity 79 to facilitate the rotation of the adjustment disk 64;

[0035] The elastic component includes a spring 77 installed on one side of the inner wall of the mounting cavity 79 and a pushing block 78 connected to one end of the spring 77. The end of the pushing block 78 away from the spring 77 is fixedly connected to the locking plate 72, and a lever 73 extending to the top of the mounting block 71 is installed on the top of the pushing block 78. A moving groove for the lever 73 to move is opened on the top of the mounting block 71, and a limiting member for limiting the lever 73 is provided on the mounting block 71. The moving groove is a waist-shaped hole. The lever 73 is cylindrical, and its top end passes through the moving groove, and is equipped with a disc-shaped handle, which is conducive to pulling the lever 73.

[0036] The limiting component includes a slot at the top of the lever 73 and a limiting rod 74 detachably mounted in the slot. Latch rods are installed on both sides of the bottom of the limiting rod 74. Two limiting holes a75 and a limiting hole b76 are provided on the top of the mounting block 71, and the two limiting holes a75 and the limiting holes b76 are respectively located on both sides of the movable slot.

[0037] When the locking plate 72 is in the state of being firmly fixed to the locking cam 74, the locking cam 73 is pressed against the locking cam 74 and the locking cam 73 is pressed against the locking cam 74. , to achieve rapid installation of the battery module, and after the battery module is installed, the limiting rod 74 can be pulled out of the slot at the top of the lever 73, so that the latch rod is pulled out of the limiting hole b76. At this time, the spring 77 drives the locking plate 72 out of the installation cavity 79 through the pushing block 78 under the action of its own elasticity, so that the locking teeth on the locking plate 72 are stuck in the tooth grooves on the outer wall of the adjusting plate 64, so as to lock and limit the adjusting plate 64, thereby preventing the bidirectional threaded rod 61 from rotating, which is conducive to the stable installation of the battery module.

[0038] Further, refer to Figure 4 and Figure 6As shown, a plurality of partitions 41 are installed on one side of the upper pressing plate 4, and a plurality of positioning holes 43 are opened at both ends of the upper pressing plate 4, and positioning blocks 67 corresponding to the positioning holes 43 are installed on both sides of one end of the two side plates 2, and the structure of the lower pressing plate 8 is the same as that of the upper pressing plate 4. Specifically, a plurality of partitions 41 and a plurality of positioning holes 43 are also installed on the lower pressing plate 8, which is beneficial to the rapid positioning of the upper pressing plate 4 and the lower pressing plate 8 and enhances the stability of the insulating bracket, and a plate groove matching the partition 41 is also opened on the insulating protective plate 3, which further realizes the positioning between the insulating protective plate 3 and the upper pressing plate 4 and the lower pressing plate 8, and is beneficial to the rapid installation between the insulating protective plate 3 and the side plate 2.

[0039] After the battery module is assembled into the insulating bracket, when the upper pressure plate 4 and the lower pressure plate 8 limit the battery module, the positioning block 67 on the side plate 2 is inserted into the corresponding positioning hole 43 to quickly position the upper pressure plate 4 and the lower pressure plate 8 between the two side plates 2, and achieve the reinforcement effect, thereby achieving stable limitation of the battery module and preventing the battery module from loosening and causing safety hazards.

[0040] Further, refer to Figure 1-Figure 3 As shown, detachable reinforcement plates 5 are installed at the middle of the top and bottom ends of the two side panels 2.

[0041] Specifically, the reinforcing plate 5 and the side plate 2 can be installed by bolt connection and fixing, and the two reinforcing plates 5 can increase the overall rigidity of the insulating bracket, improve the stability of the insulating bracket, and prevent the insulating bracket from deformation.

[0042] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
