[0025] The following will be combined with the drawings in the utility model to clearly and completely describe the technical solution in the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 8 , this embodiment provides a technical solution:

[0027] A detachable lithium battery assembly frame includes a box body 1, the top and bottom ends of the box body 1 are respectively fixedly connected with an upper cooling liquid plate 2 and a lower cooling liquid plate 3, the four vertical outer walls of the box body 1 are connected to a protective shell 4 through a plurality of shock-absorbing springs 12, a plurality of equal and corresponding limiting plates 13 are welded to the inner walls on the left and right sides of the box body 1, and an installation groove 14 is opened between every two adjacent limiting plates 13 on the same side of the left and right inner walls of the box body 1, and the inside of the installation groove 14 is connected to the same clamping block 142 through at least two telescopic rods 141, and an installation spring 143 is sleeved on the outside of the telescopic rod 141, and every four matrix-distributed limiting plates 13 in the box body 1 are surrounded to form a partition groove for installing a lithium battery 6.

[0028] In this embodiment, screws 11 are fixedly installed at the four corners of the top and bottom surfaces of the box body 1, and through holes for accommodating the screws 11 at the corresponding positions are opened at the four corners of the upper cooling liquid plate 2 and the lower cooling liquid plate 3. The screws 11 are threadedly connected with matching nuts for fixing the upper cooling liquid plate 2 or the lower cooling liquid plate 3. A handle 21 is welded at the middle position of the top of the upper cooling liquid plate 2 to facilitate users to carry and transport.

[0029] In this embodiment, a heat conducting plate 5 is bonded to the bottom surface of the upper cold liquid plate 2 and the top surface of the lower cold liquid plate 3. The upper cold liquid plate 2 and the lower cold liquid plate 3 are both adapted to the shape and size of the cross section of the box body 1. The heat conducting plate 5 absorbs the heat generated by the lithium battery 6 to enhance the heat dissipation effect.

[0030] In this embodiment, the protective shell 4 is adapted to the shape and size of the corresponding outer wall of the box body 1. The protective shell 4 is made of plastic. One end of the shock-absorbing spring 12 is fixed to the side wall of the protective shell 4 by glue, and the other end is fixed to the outer wall of the box body 1 by glue, thereby enhancing the anti-collision function of the box body 1.

[0031] In this embodiment, the clamp block 142 is in the shape of a rectangular parallelepiped and the side of the top away from the mounting groove 14 is in the shape of an arc. When the telescopic rod 141 is compressed to the shortest, its minimum length is less than the depth of the mounting groove 14. The longitudinal cross-sectional dimension of the clamp block 142 is less than or equal to the slot dimension of the mounting groove 14, so that when the lithium battery 6 is installed, the clamp block 142 can be pressed into the corresponding mounting groove 14. At the same time, the arc shape can facilitate the installation of the lithium battery 6 into the box body 1, and avoid the right-angled edges at the top of the clamp block 142 affecting the installation of the lithium battery 6.

[0032] In this embodiment, the partition groove is adapted to the outer shape and size of the lithium battery 6, the length of the lithium battery 6 is smaller than the inner width of the box body 1, and the height of the lithium battery 6 is smaller than the inner height of the box body 1. The bottom of the heat conducting plate 5 located on the bottom surface of the upper cold liquid plate 2 is in contact with the top of the lithium battery 6. The heat conducting plate 5 is preferably made of non-metallic thermally conductive material (such as aluminum oxide, silicon oxide, zinc oxide, aluminum nitride, boron nitride, silicon carbide, graphite, etc.) to enhance heat dissipation and is non-conductive, thereby avoiding safety hazards caused by leakage of the lithium battery 6.

[0033] In this embodiment, two poles 61 are provided at the bottom of the lithium battery 6, and a series terminal row 15 is clamped in the bottom of the box body 1. The top surface of the series terminal row 15 is provided with a plurality of docking holes for accommodating the insertion of the poles 61 at corresponding positions. A plurality of decompression springs 151 are provided at the left and right edges of the top of the series terminal row 15. The number of the decompression springs 151 is equal to the number of the mounting grooves 14 and the positions correspond one to one. The decompression springs 151 arranged at the top of the series terminal row 15 can prevent the poles from being crushed.

[0034] Finally, it should be noted that the series terminal block 15, upper cooling liquid plate 2, lower cooling liquid plate 3, lithium battery 6, etc. involved in the present invention are all universal standard parts or parts known to technical personnel in this field, and their structures and principles are all known to technical personnel in this field through technical manuals or through conventional experimental methods. In the idle space of this device, all the above-mentioned electrical components, which refer to power elements, electrical components, and adapted controllers and power supplies, are connected through wires. The specific connection means should refer to the working principle of the present invention. The electrical connection between each electrical component is completed in a sequential working order, and the detailed connection means are all well-known technologies in the field.

[0035] When installing the detachable lithium battery assembly frame of the present invention, a tool is first used to separate the upper cooling liquid plate 2 from the screw rod 11, and the pole 61 of the lithium battery 6 is pressed down against the groove at the top end of the series terminal row 15. After the clamping block 142 contacts the lithium battery 6, the force affects the telescopic rod 141 and the installation spring 143 to shrink. After the lithium battery 6 is fixed on the series terminal row 15, the decompression spring 151 can prevent the pole from being crushed. The clamping block 142 rebounds under the influence of the restoring force of the installation spring 143. After the lithium battery 6 is fixed in the box body 1, the upper cooling liquid plate 2 is fixed to the screw rod 11 again using a tool, and the bottom end of the heat conducting plate 5 bonded to the bottom of the upper cooling liquid plate 2 contacts the top of the lithium battery 6 to prevent the lithium battery 6 from being ejected out of the box body 1 due to the elastic force of the decompression spring 151. When disassembling, after the upper cooling liquid plate 2 is separated from the screw rod 11 using a tool, the lithium battery 6 is directly pulled out of the box body 1.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
