DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0036] like Figures 1 to 6As shown, a cylindrical lithium battery pack mounting bracket includes a lower support 1 and at least three support rods 3 fixed on the lower support 1, the top of the support rod 3 is fixedly connected to the upper support 4, the upper surface of the lower support 1 is provided with a plurality of battery jacks, and the lower surface of the lower support 1 is provided with a plurality of battery slots. When the cylindrical lithium battery is installed, one end of the cylindrical lithium battery can be inserted into the battery slot through the battery slot, and the other end of the cylindrical lithium battery is left in the battery slot, so that the preliminary installation of the cylindrical lithium battery can be completed. The cylindrical lithium battery pack mounting bracket also includes:

[0037] A connecting component 2 is used for assembling and connecting two adjacent lower supports 1.

[0038] The connection assembly 2 includes at least one female connection member 21 and a sub-connection member 22 arranged on the lower support 1. When the two lower supports 1 are assembled, the female connection member 21 and the sub-connection member 22 on the opposite surfaces of the two lower supports 1 match.

[0039] The sub-connecting member 22 includes a connecting block 221 fixed on the lower support 1 and a limiting insertion hole 222 arranged on the upper surface of the connecting block 221 .

[0040] The female connector 21 includes a slot 211 disposed on the lower support 1 . When two lower supports 1 are connected to each other, the connecting blocks 221 on the opposite surfaces of the two lower supports 1 will be inserted into the matching slot 211 .

[0041] A limiting insert block 215 is slidably connected to a receiving groove 213 disposed on an inner upper surface of the slot 211 .

[0042] A pull rod 214 is fixed to the upper surface of the limiting insert block 215 , and one end of the pull rod 214 passes through a through slot 212 provided on the inner upper surface of the receiving slot 213 .

[0043] The tension spring 216 is slidably mounted on the outside of the top end of the pull rod 214 , and the two ends of the tension spring 216 are respectively fixed on the top end of the pull rod 214 and the upper surface of the lower support 1 .

[0044] When the two lower supports 1 are assembled with each other, first pull the top end of the pull rod 214 so that the limit plug 215 is stored in the storage groove 213, and then insert the connecting block 221 on one of the lower supports 1 into the slot 211 on the other lower support 1, and then release the pull rod 214. Under the elastic force of the tension spring 216, the pull rod 214 and the limit plug 215 move downward synchronously, and the limit plug 215 is inserted into the limit plug hole 222, thereby realizing a fixed connection between the two lower supports 1, simplifying the assembly or disassembly action between multiple lower supports 1, increasing the speed of assembly or disassembly between multiple lower supports 1, and reducing the difficulty of assembly or disassembly operations.

[0045] In this embodiment, the connecting block 221 matches the slot 211, and the limiting hole 222 matches the limiting block 215. When assembled between multiple lower supports 1, the connecting blocks 221 on the opposite surfaces of two adjacent lower supports 1 can be inserted into the matching slot 211, and the limiting block 215 can be vertically inserted into the limiting hole 222 to achieve locking and fixation between the two lower supports 1.

[0046] In this embodiment, the cylindrical lithium battery pack mounting bracket further includes:

[0047] The top seal 5 is detachably mounted on the upper surface of the upper support 4 and is fixed to the upper surface of the upper support 4 by two or three bolts or screws, so that the top seal 5 can be quickly removed before the cylindrical lithium battery is filled. The top seal 5 is used to seal the top of the upper support 4.

[0048] A plurality of top sealing covers 6 are arranged on the top sealing member 5, and the top sealing covers 6 are used to seal the battery slots on the upper support 4. When filling cylindrical lithium batteries between the lower support 1 and the upper support 4, the top sealing member 5 can be removed as a whole to facilitate quickly filling the cylindrical lithium batteries between the lower support 1 and the upper support 4, and then the top sealing member 5 is installed on the upper surface of the upper support 4, so as to improve the efficiency of filling the cylindrical lithium batteries. When it is necessary to replace a single cylindrical lithium battery, the cylindrical lithium battery can be replaced by removing the top sealing cover 6 on the corresponding cylindrical lithium battery, which can not only efficiently fill the cylindrical lithium batteries, but also efficiently replace a single cylindrical lithium battery.

[0049] In this embodiment, the top sealing member 5 includes a top sealing plate 51 detachably mounted on the upper surface of the upper support 4 and a plurality of material extraction ports 52 arranged on the top sealing plate 51. At least one special-shaped groove 53 is arranged on the inner wall of the material extraction port 52. The material extraction port 52 matches the cylindrical lithium battery, so that when a single cylindrical lithium battery needs to be replaced, the new cylindrical lithium battery can be quickly taken out and replaced, and the freedom of the cylindrical lithium battery can be constrained in the radial and axial directions.

[0050] In this embodiment, the top cover 6 includes:

[0051] The sealing block 61 is slidably mounted in the material taking port 52 .

[0052] The protrusion 62 is fixed on the sealing block 61 .

[0053] An elastic pressing piece 63 is fixed on the protrusion 62 .

[0054] The convex strip 64 fixed on the upper surface of the sealing block 61, when the top sealing cover 6 is installed in the feeding port 52, the convex block 62 is first aligned with the opening at the top of the special-shaped groove 53, and the axis of the sealing block 61 and the feeding port 52 are coincident, and then the sealing block 61 is pressed down along the axial direction of the feeding port 52, so that the pressed sealing block 61 falls into the feeding port 52 until the lower surface of the convex block 62 contacts the lower surface of the inner wall of the special-shaped groove 53, and then the sealing block 61 is rotated so that the convex block 62 is completely hidden in the special-shaped groove 53. While rotating the sealing block 61, the top end of the elastic pressing sheet 63 is squeezed against the inner wall of the special-shaped groove 53 and elastically deformed until the elastic pressing sheet 63 is completely received in the special-shaped groove 53 in the horizontal direction. At this time, the upper surface of the elastic pressing sheet 63 tightly contacts the upper surface of the inner wall of the special-shaped groove 53, so as to increase the friction between the elastic pressing sheet 63 and the special-shaped groove 53 in the horizontal direction, thereby avoiding the sealing block 61 from loosening in the circumferential direction and affecting the limiting and fixing effect of the cylindrical lithium battery.

[0055] In this embodiment, the circumferential shape of the special-shaped groove 53 along the feeding port 52 is L-shaped, and the special-shaped groove 53 matches the protrusion 62. After the sealing block 61 is installed in the feeding port 52, it is convenient to constrain the freedom of the protrusion 62, so as to achieve the effect of limiting and fixing the sealing block 61, so that the sealing block 61 can seal the feeding port 52 more firmly. When a single cylindrical lithium battery needs to be replaced, the sealing block 61 corresponding to the cylindrical lithium battery to be replaced can be quickly disassembled and quickly installed back in place after replacement. The operation is simple and convenient, which improves the efficiency of replacing a single cylindrical lithium battery.

[0056] The above description is only the preferred embodiment of the utility model, and the parts not described in the utility model can be implemented by adopting or drawing on existing technologies. Of course, the above description is not a limitation of the utility model, and the utility model is not limited to the above examples. The changes, modifications, additions or substitutions made by technicians in this technical field within the essential scope of the utility model should also fall within the protection scope of the utility model.
