Description

Technical Field

[0001] The utility model belongs to the technical field of battery modules, and in particular relates to a battery module with a protective base. Background Art

[0002] Lithium battery is a battery that uses lithium metal or lithium alloy as the negative electrode material and non-aqueous electrolyte solution. Lithium battery module is a battery module composed of multiple lithium batteries and has a large storage capacity.

[0003] Most of the existing battery module mounting bases are fixed and cannot be adjusted according to battery modules of different specifications, which reduces their practicality. In addition, the base shell and the cover plate are mostly fixed by bolts. The bolts are prone to rust or stripping after long-term use. When the battery module is damaged, it is difficult for the staff to repair or replace it in time, which makes the operation inconvenient and affects the work efficiency. Utility Model Content

[0005] In order to solve the above technical problems, the utility model is achieved through the following technical solutions:

[0006] The utility model discloses a battery module with a protective base, comprising a base shell, a snap-fit ​​cover and a battery main body, wherein a bidirectional spiral rod is rotatably connected inside the base shell, the threads on the left and right sides of the bidirectional spiral rod are opposite, and thread blocks are spirally connected to the two sides of the bidirectional spiral rod, the upper surface of the thread block is fixedly connected to a fixing rod, one side of the thread block is slidably connected to a bearing plate, the bearing plate is "L"-shaped, one side of the bearing plate is fixedly connected to a fixing block, a matching spring is installed between the bottom surface of the fixing block and the upper surface of the fixing rod, and the battery main body is arranged inside the base shell and on the surface of the bearing plate.

[0007] The inner bottom surface of the base shell is provided with a plurality of groups of grooves, and a vibration-damping spring is fixedly connected inside the groove, and one end of the vibration-damping spring is arranged below the supporting plate; by arranging the vibration-damping spring, the vibration amplitude of the battery module is further reduced to avoid damage to the battery body when it is vibrated.

[0008] The top of the base shell is open, the buckle cover is arranged on the top of the base shell and buckled with it, a plurality of buckle blocks are fixedly connected to the circumference of the top of the base shell, and the surface of the buckle blocks is provided with snap-fit ​​holes.

[0009] Buckle assemblies are provided on both sides of the upper surface of the snap-fit ​​cover, and the buckle assemblies include slide rails and snap-fit ​​plates. The slide rails and snap-fit ​​plates are provided in two groups, and the two groups of slide rails are respectively provided on both sides of one end of the snap-fit ​​cover, and the two groups of snap-fit ​​plates are respectively provided inside the two groups of slide rails and slidably cooperate with them.

[0010] The snap-in plate is "L"-shaped, and one end of the snap-in plate extends out of the slide rail and slides and engages with the snap-in hole. A compression spring is installed between the two groups of the snap-in plates. By setting the snap-in block, the snap-in hole, the snap-in cover and the snap-in assembly, the snap-in plate can be squeezed inward to slide in the slide rail, thereby releasing the snap-in with the snap-in hole, making it easy to disassemble and assemble the snap-in cover, and thus facilitating the maintenance or replacement of the battery module inside the base shell.

[0011] One end of the bidirectional spiral rod is fixedly connected with a handle, and the handle is arranged on the outer side of the base shell.

The bidirectional spiral rod can be rotated according to battery modules of different specifications, and then the distance between the two groups of bearing plates can be adjusted, so that battery modules of different specifications can be clamped and installed. With the cooperation of the fixing rod, the fixing block and the matching spring, the vibration damping effect of the bearing plate is improved to prevent the battery module from being damaged. By providing a snap-fit ​​block, a snap-fit ​​hole, a snap-fit ​​cover and a snap-fit ​​assembly, the snap-fit ​​plate can be squeezed inward to slide in the slide rail, and then the snap-fit ​​with the snap-fit ​​hole can be released, so that the snap-fit ​​cover is easy to disassemble and assemble, and then the battery module inside the base shell can be maintained or replaced.
