Description

Technical Field

[0001] The utility model belongs to the technical field of battery boxes, and in particular relates to a slide rail type battery box which is easy to maintain. Background Art

[0002] A battery box, also known as a battery tray or battery box, is a battery pack consisting of several single cells, a box, a battery management system, and related mounting components. A slide-type battery box typically consists of the box, slide rails, battery modules, and a locking mechanism. The slide rails are mounted on the inner wall of the box, and the battery modules slide into the box via the rails, facilitating quick installation and removal. The locking mechanism ensures the stability of the battery modules within the box, preventing them from shifting or falling out during driving.

[0003] Publication No. "CN217086785U" discloses a slide-rail battery box. This utility model comprises a box body, comprising two brackets. Two pairs of parallel linear guide rails are disposed on the inner wall of the box body. These two pairs of linear guide rails are staggered and point toward the openings at each end of the box body. Each pair of linear guide rails is slidably provided with a slide bar. The two brackets are symmetrically secured to the two pairs of slide bars. Locking structures are provided at both ends of the brackets, near the box body openings. These locking structures engage the box body, and window doors are provided at each end of the box body openings. This utility model is applicable to the technical field of battery boxes.

[0004] Although the above-mentioned utility model opens several elastic locks on both sides of the box, pulls out the window door through the second handle, and then opens the locking structure, pulls out the bracket through the first handle, and the bracket slides out of the box through the staggered linear guide rails, so that the battery can be maintained. However, when pulling the bracket, the bracket relies on sliding friction to achieve movement. Due to the large resistance of sliding friction and the weight of the batteries on the bracket, the bracket may encounter greater difficulties during movement and requires greater external force to push. Currently, pulleys are installed at the bottom of the bracket on the market to solve the problem of large resistance of sliding friction. However, when the pulley fails due to long-term use or wear, the mobility of the bracket will be restricted, which will directly affect the normal use of the battery box, thereby reducing the reliability of the system, and the entire battery box or bracket needs to be disassembled and repaired, which will increase maintenance costs. Utility Model Content

[0005] In response to the problems mentioned in the background technology, the purpose of the present invention is to provide a slide-rail battery box that is easy to maintain, so as to solve the problem of large resistance to sliding friction caused by installing a pulley at the bottom of the bracket. However, when the pulley fails due to long-term use or wear, the mobility of the bracket will be restricted, which will directly affect the normal use of the battery box, thereby reducing the reliability of the system, and the entire battery box or bracket needs to be disassembled and repaired, which will lead to increased maintenance costs.

The movable plate 123 is slidably connected to the inside of the cavity 121. The end of the movable plate 123 away from the first return spring 122 is fixedly connected to the locking block 124. The end of the locking block 124 away from the movable plate 123 extends to the side end of the mounting seat 5. The upper end of the locking block 124 is set as an inclined surface. The bottom end of the bracket 3 is symmetrically provided with a mounting groove 4 near the chamfer. The mounting groove 4 is plugged into the mounting seat 5. The locking groove 13 is provided at one end inside the mounting groove 4, and the other end of the locking groove 13 passes through the bracket 3. The locking groove 13 is snap-connected with the locking block 124, and the pulley 6 is merged with the bottom end of the bracket 3 so that the mounting seat 5 is inserted into the mounting groove 4. During the insertion process, the extrusion force exerts pressure on the inclined surface of the upper end of the locking block 124, so that the locking block 124 drives the movable plate 123 to compress the first return spring 122, and the locking block 124 retracts into the cavity 121. Then, when the locking block 124 moves to the locking groove 13, the first return spring 122 is reset, and the movable plate 123 rebounds and drives the locking block 124 to pop out.

The locking block 124 ends the engagement with the locking groove 13, and then the pulley 6 is pulled downward to end the insertion of the mounting seat 5 and the mounting groove 4, completing the disassembly of the pulley 6.

The positioning hole 18 and the positioning column 173 are snap-fitted, and the pulley 6 is merged with the bottom end of the bracket 3 so that the mounting base 5 is inserted into the mounting groove 4. During the insertion process, the extrusion force exerts pressure on the arc surface of the positioning column 173, so that the positioning column 173 compresses the second return spring 172, and the positioning column 173 retracts into the built-in hole 171. Then, when the positioning column 173 moves to the built-in hole 171, the second return spring 172 is reset, and the positioning column 173 pops out. The positioning column 173 is snap-fitted and fixed to the positioning hole 18, completing the positioning of the pulley 6 during installation.

The second sliding block 10 is slidingly connected to the second sliding groove 11. Pull the bracket 3 outward so that the pulley 6 at the bottom end of the bracket 3 slides inside the sliding groove 7. At the same time, when the bracket 3 moves, the bracket 3 drives the first sliding groove 9 and the second sliding groove 11 to slide on the outside of the first sliding block 8 and the second sliding block 10.

[0027] Principle and advantages of use: First, pull the bracket 3 outward so that the pulley 6 at the bottom end of the bracket 3 slides inside the slide groove 7. At the same time, when the bracket 3 moves, the bracket 3 drives the first sliding groove 9 and the second sliding groove 11 to slide outside the first sliding block 8 and the second sliding block 10, and pulls the bracket 3 out of the battery box body 1. Move the unlocking block 14 so that the unlocking block 14 slides inside the locking groove 13. At the same time, the unlocking block 14 drives the limiting block 15 to slide inside the limiting groove 16. The unlocking block 14 pushes the locking block 124, so that the locking block 124 drives the moving plate 123 to compress the first return spring 122, and the locking block 124 retracts into the cavity 121, and the locking block 124 and the locking groove 13 end the card Then, pulley 6 is pulled downward to complete the insertion of mounting seat 5 and mounting groove 4, and the pulley 6 is disassembled and maintained. After the maintenance is completed, pulley 6 is merged with the bottom end of bracket 3 so that mounting seat 5 is inserted into the mounting groove 4. During the insertion process, the extrusion force exerts pressure on the inclined surface of the upper end of locking block 124, so that the locking block 124 drives the movable plate 123 to compress the first return spring 122, and the locking block 124 retracts into the cavity 121. Then, when the locking block 124 moves to the locking groove 13, the first return spring 122 is reset, and the movable plate 123 rebounds and drives the locking block 124 to pop out, and the locking block 124 is clamped and fixed with the locking groove 13, completing the installation of the pulley 6;
