Detailed Implementation

[0018] The embodiments of the present invention will now be described in detail with reference to the accompanying drawings. These embodiments are merely illustrative of the present invention and should not be construed as limiting the scope of protection of the present invention.

[0019] It should be noted that, unless otherwise stated, the technical or scientific terms used in this application shall have the ordinary meaning as understood by one of ordinary skill in the art to which this utility model pertains.

[0020] Example: like Figure 1-8 As shown, this embodiment provides a quick-replacement battery holder, including: Mounting plate 1 and battery box 11 are provided. A quick-release assembly is provided between mounting plate 1 and battery box 11. A top plate 12 is detachably and fixedly connected to the upper end of battery box 11. The top plate 12 can fix the battery inside battery box 11. A mounting ear 24 is fixedly mounted on the upper side of the battery box 11. A long bolt 241 is mounted between the mounting ear 24 and the top plate 12. The long bolt 241 is slidably connected to the side of the top plate 12. The long bolt 241 is threadedly fixed to the mounting ear 24. The top plate 12 can be fixedly mounted on the upper end of the battery box 11 by the long bolt 241.

[0021] The mounting plate 1 has several mounting holes 25, through which workers can fix the mounting plate 1 to the corresponding part of the vehicle.

[0022] Mounting arches 26 are provided on both the front and rear sides of the upper end of the mounting plate 1. The mounting arches 26 can raise the installation height of the battery box 11, providing space for quick-release components and increasing air circulation at the bottom.

[0023] The battery box 11 is fixedly provided with a support foot 27 at the lower end, and the mounting plate 1 is provided with an assembly groove 271 that matches the support foot 27 at the upper end. The matching of the support foot 27 and the assembly groove 271 can facilitate the quick positioning of the battery box 11 during installation and reduce the installation difficulty.

[0024] There are four quick-release components, and each pair is located on the left and right sides between the mounting plate 1 and the battery box 11. The quick-release components on both sides are symmetrically arranged, which improves the overall stability of the battery box 11 installation.

[0025] The quick-release components include: The adjusting cylinder 13 is rotatably mounted on the lower end of the battery box 11, and a fixing block 131 is fixedly mounted on the side of the adjusting cylinder 13. Support column 14 is fixedly assembled to the bottom of battery box 11, and adjusting cylinder 13 is rotatably sleeved on the outside of support column 14; A torsion spring 15 is installed between the adjusting cylinder 13 and the support column 14, with its two ends fixedly connected to the adjusting cylinder 13 and the support column 14, respectively. Pull rope 16 is wound around the adjusting cylinder 13, and one end is fixedly connected to the side of the adjusting cylinder 13. By pulling the pull rope (16), the other end of the pull rope (16) can pull the adjusting cylinder (13) to rotate. Pulling the pull rope 16 can drive the adjusting cylinder 13 to rotate. The adjusting cylinder 13 overcomes the elastic force of the torsion spring 15 and drives the fixed block 131 to rotate. When the pull rope 16 is released, the adjusting cylinder 13 rotates back to its original position by relying on the reset elasticity of the torsion spring 15. The battery box 11 is equipped with a webbing 22 on its side, one end of which is fixedly connected to the other end of the pull rope 16.

[0026] A limiting groove 23 is fixedly provided on the bottom side of the battery box 11. A slider 231 is slidably mounted inside the limiting groove 23. The slider 231 is fixedly mounted between the webbing 22 and the pull rope 16.

[0027] Among them, the two pull ropes 16 on the left and right sides are fixedly connected to the webbing 22 on the same side. The webbing 22 is an object that is easy for operators to use. By pulling the webbing 22, the two pull ropes 16 on the same side can be moved. The cooperation between the limiting groove 23 and the slider 231 limits the length of the pull rope 16, avoiding excessive pulling distance and irreversible damage to the torsion spring 15. With the support of the slider 231 and the limiting groove 23, the operator can lift the battery box 11 through the webbing 22 on both sides, which is conducive to the movement and disassembly of the battery box 11. Mounting cylinder 17 is fixedly mounted on the upper end of mounting plate 1. Adjusting cylinder 13 slides up and down and rotates in match with mounting cylinder 17. The side of mounting cylinder 17 is provided with an L-shaped slot 171 that slides in match with fixing block 131. When fixing block 131 rotates into L-shaped slot 171, it can limit the fixing of battery box 11.

[0028] A protective ring 21 is fixedly mounted on the bottom of the battery box 11. The protective ring 21 is sleeved on the outside of the adjusting cylinder 13. A groove is opened on the outside of the protective ring 21 to slide and connect with the pull rope 16. The protective ring 21 is used to protect the pull rope 16 and prevent it from derailing.

[0029] The working principle of the embodiments is explained in detail below: When installing the battery box 11, the mounting plate 1 is first fixedly installed at the vehicle battery mounting location through the mounting hole 25. The operator pulls the webbing 22 from both sides to move the pull rope 16, so that the adjusting cylinder 13 and the fixing block 131 rotate to the installation position. At this time, the slider 231 also abuts against the limiting groove 23 to provide support. Then the operator lifts the battery box 11 through the webbing 22. The support foot 27 at the bottom of the battery box 11 and the assembly groove 271 on the mounting plate 1 make it easy for the battery box 11 to be positioned. At this time, lowering the battery box 11 allows the adjusting cylinder 13 and the fixing block 131 to slide down to the inside of the mounting cylinder 17 and the L-shaped slot 171. Then the operator can loosen the webbing 22, and the torsion spring 15 will return the adjusting cylinder 13 to its original position by relying on its own restoring elasticity. The fixing block 131 will then enter the bottom of the L-shaped slot 171, thereby achieving a stable connection between the battery box 11 and the mounting plate 1. Similarly, when disassembling the battery box 11, the operator can quickly release the restriction between the fixing block 131 and the L-shaped slot 171 by pulling the webbing 22 on both sides upwards. This facilitates the operator to quickly disconnect the connection between the battery box 11 and the mounting plate 1. The symmetrical design of the quick-release component ensures the stability of the battery box 11 during installation, while the design of the mounting arch 26 provides space for air circulation at the bottom and raises the installation height of the battery box 11, making it easier to operate the quick-release component. The entire installation process is simple and efficient, significantly improving the speed and convenience of battery rack replacement.
