[0028] In the embodiment of the present disclosure, the clamping bracket 2 is a concave-shaped folded plate structure. Two groups of through slots and two groups of through holes are symmetrically provided on the front side of the clamping bracket 2. The diameter of the through hole of the clamping bracket 2 is equal to the outer diameter of the clamping bracket 2. By using the two groups of through slots on the front side of the clamping bracket 2, it is convenient for the air to circulate in the front-rear direction at the bottom of the battery box 401, which is beneficial to the natural heat dissipation at the bottom of the battery box 401.
[0029] In the embodiment of the present disclosure, the number of the sliding frames 404 is two groups. The sliding frames 404 are symmetrically distributed on the front and rear sides of the support plate 407. Convex plates are provided at positions near the left end and the right end of the bottom of each group of sliding frames 404. Plug rods 405 are welded to each group of convex plates. The plug rods 405 are opposite to the through holes of the clamping bracket 2 in the front and rear directions. Threaded through holes that penetrate through the front and rear are provided in the center of each group of sliding frames 404. The positive threaded end of the outer side of the bidirectional threaded rod 409 is meshed and connected to the threaded through hole of the front-side sliding frame 404, and the reverse threaded end of the outer side of the bidirectional threaded rod 409 is meshed and connected to the threaded through hole of the rear-side sliding frame 404. Through hole structures that penetrate through the front and rear are symmetrically provided on the left and right sides of the threaded through hole of the sliding frame 404. The two groups of guide rods 410 are respectively inserted into the through holes of the sliding frame 404. The two groups of sliding frames 404 move synchronously in opposite directions in the front and rear directions by driving the bidirectional threaded rod 409 by the knob 408, so that the plug rods 405 welded to the convex plate parts of the sliding frames 404 are inserted into the through holes of the clamping bracket 2, completing the quick locking and installation work of the RV battery pack 4 on the clamping bracket 2, and the installation operation is convenient and fast.
[0030] In the embodiments of the present disclosure, the number of side frames 1 is two groups, and the side frames 1 are symmetrically distributed left and right. Each group of side frames 1 has an L-shaped folding plate structure. Six groups of triangular plates are provided inside the L-shaped folding plate of the side frame 1. By using the triangular stable structure, the structural strength of the L-shaped folding plate of the side frame 1 is enhanced. A long strip through groove that penetrates left and right is provided on the left side surface of the side frame 1, facilitating the air circulation in the left-right direction at the bottom of the battery box 401 and being beneficial to the natural heat dissipation at the bottom of the battery box 401.
[0031] In the embodiments of the present disclosure, the underframe 402 has a rectangular frame structure that penetrates up and down. Through holes and support plates are respectively provided on the front side surface and the rear side surface inside the frame of the underframe 402 from top to bottom. The front end and the rear end of the bidirectional threaded rod 409 are rotatably connected in the two through holes of the underframe 402. A through groove that penetrates up and down is provided at the center of the support plate of the underframe 402. The knob 408 is inserted into the through groove of the support plate of the underframe 402, so that the knob 408 is hidden in the through groove of the underframe 402. This not only compresses the spatial distribution of the installation structure of the RV battery pack 4, but also avoids the situation of accidental touch caused by the exposure of the knob 408.
[0032] In the embodiments of the present disclosure, the number of foot seats 403 is four groups. The foot seats 403 are respectively welded to the four corner positions on the lower side surface of the underframe 402. Through holes that penetrate front and back are provided on each foot seat 403. The insertion rod 405 is inserted into the through hole of the foot seat 403, so that the insertion rod 405 locks the RV battery pack 4 through the through holes of the foot seat 403 and the through holes of the clamping bracket 2.
[0033] In the embodiments of the present disclosure, the end of the insertion rod 405 has a hemispherical structure, which is convenient for guiding the insertion rod 405 to quickly insert into the through holes of the clamping bracket 2 and the foot seat 403, and avoids the situation where the insertion rod 405 is stuck due to the slight misalignment of the through holes of the clamping bracket 2 and the foot seat 403 during the insertion process of the insertion rod 405 at the through holes of the clamping bracket 2 and the foot seat 403.
[0034] The specific usage mode of this embodiment:
[0035] When the RV lithium battery pack is replaced and installed, the utility model places the RV battery pack 4 on the upper side of the two groups of clamping brackets 2. At this time, the two groups of foot seats 403 near the front end of the lower side of the bottom frame 402 are located on the front side of the front clamping bracket 2, and the two groups of foot seats 403 near the rear end of the lower side of the bottom frame 402 are located on the rear side of the rear clamping bracket 2. The through holes of the clamping bracket 2 and the through holes of the foot seats 403 are opposite to each other front and back. Then, the knob 408 in the through groove at the center position of the support plate of the bottom frame 402 is moved with a finger, and the knob 408 drives the bidirectional threaded rod 409 to rotate. Since the positive threaded end and the reverse threaded end of the outer side of the bidirectional threaded rod 409 are respectively engaged and connected in the threaded through holes of the two groups of sliding frames 404, the bidirectional threaded rod 40 9 drives the two groups of sliding frames 404 to move synchronously in opposite directions along the guide rods 410. The plug rods 405 welded and connected at the two groups of convex plates at the bottom of each group of sliding frames 404 move synchronously with the sliding frames 404 until the plug rods 405 penetrate into the through holes of the positioning bracket 2 and the through holes of the foot seat 403 in turn, so that the plug rods 405 cooperate with the through holes of the foot seat 403 to complete the locking work of the RV battery pack 4 at the through holes of the positioning bracket 2, and complete the installation of the RV lithium battery pack. When the lithium battery pack is replaced and disassembled, it is only necessary to turn the knob 408 in the opposite direction, and the two-way threaded rod 409 drives the plug rods 405 welded and connected on the sliding frame 404 to disengage from the through holes of the positioning bracket 2 and the through holes of the foot seat 403, and then the RV battery pack 4 can be picked up.
[0036] The installation, connection or setting methods of all the above components are common mechanical methods, such as welding, threaded connection, screw connection, etc., and the specific structures, models and coefficient indicators of all its components are its own technology, as long as it can achieve its beneficial effects, it can be implemented. The battery box 401 used above is a common device on the market. When you buy it back and use it, you only need to connect it according to the instruction manual purchased together, so I will not repeat it here.
[0037] The technical solution of the present invention is not limited to the scope of the embodiments of the present invention, and the technical contents not described in detail in the present invention are all well-known technologies.
