DETAILED DESCRIPTION

[0023] The technical solution in the embodiment of the present application is to solve the above-mentioned hot weather, the battery needs to be cooled, and the device is not convenient for cooling the battery. The overall idea is as follows:

[0024] Please refer to Figures 1-5 A new energy bus heat insulation and energy reduction device, comprising a base 1.

[0025] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5The base 1 is provided with a heat insulation box 2, and a wire slot 21 is formed in the side wall of the heat insulation box 2. Specifically, the base 1, the heat insulation box 2, the first heat insulation cover plate 3, the second heat insulation cover plate 4, the heat insulation connecting cover plate 5 and the baffle 7 are all heat insulation plates, and the heat insulation effect is good. The heat insulation box 2 is provided with a baffle 7 that can slide at the wire slot 21, and the heat insulation box 2 is fixedly connected with the first heat insulation cover plate 3 and the second heat insulation cover plate 4 at the top of the two sides, respectively. The heat insulation connecting cover plate 5 is slidably arranged in the second heat insulation cover plate 4, and can slide into the first heat insulation cover plate 3 and seal the top of the heat insulation box 2. The battery of the bus is installed on the base 1 and located in the heat insulation box 2. When the battery needs to be heat-insulated in winter, the heat insulation connecting cover plate 5 is pulled to seal the top of the heat insulation box 2, so as to realize heat insulation of the battery. In summer, the heat insulation connecting cover plate 5 is pulled again to expose the opening at the top of the heat insulation box 2, so as to facilitate heat dissipation of the battery. The wires of the bus can pass through the wire slot 21 to facilitate circuit connection. The heat insulation connecting cover plate 5 cooperates with the first heat insulation cover plate 3 and the second heat insulation cover plate 4 to open or seal the top of the heat insulation box 2 according to the actual temperature, so that the battery can be heat-insulated in winter and effectively cooled in summer, and the heat insulation box 2 can be changed according to the actual situation, improving the practicability of the heat insulation box 2. Through the arrangement of the baffle 7, the size of the wire slot 21 can be changed, so that the excess part of the wire slot 21 can be sealed after the wire passes through the wire slot 21, preventing external air from entering when the battery needs to be heat-insulated, and improving the heat insulation effect.

[0026] The first heat insulation cover plate 3 and the second heat insulation cover plate 4 are respectively provided with first elastic sealing gaskets 32 and second elastic sealing gaskets 42 in contact with the two ends of the heat insulation connecting cover plate 5. The first elastic sealing gaskets 32 and the second elastic sealing gaskets 42 cooperate to make the two ends of the heat insulation connecting cover plate 5 in contact with the first heat insulation cover plate 3 and the second heat insulation cover plate 4 without gaps and can limit the heat insulation connecting cover plate 5 to prevent movement.

[0027] The first accommodating groove 23 is arranged on the side wall of the heat insulation box 2 on the side of the threading groove 21 and cooperates with the baffle 7. The outer side of the baffle 7 is provided with the limiting piece 8. The limiting piece 8 comprises the connecting column 81 which is fixedly connected with the baffle 7. The outer end of the connecting column 81 is fixedly connected with the vertical plate 82. The inner side of the vertical plate 82 is provided with the abutting spring 83. The other end of the abutting spring 83 is connected with the abutting plate 84 which is in sliding abutment with the side wall of the heat insulation box 2. The top end and the bottom end of the baffle 7 are fixedly connected with the plug plate 71. The top wall and the bottom wall of the heat insulation box 2 on the side of the threading groove 21 are provided with the plug groove 24 which cooperates with the plug plate 71. When the wires of the battery pass through the threading groove 21, the connecting column 81 is pulled to move the baffle 7 to electrically contact the baffle 7 to fix the wires in the threading groove 21 and seal the gap. At this time, the abutting plate 84 is in abutment with the side wall of the heat insulation box 2 under the cooperation of the abutting spring 83 to limit and fix the baffle 7.

[0028] The handle 6 is arranged on the end of the heat insulation connecting cover plate 5 close to the first heat insulation cover plate 3. The handle 6 makes the heat insulation connecting cover plate 5 more smooth when moving.

[0029] The lower surface of the two ends of the heat insulation connecting cover plate 5 is fixedly connected with the sliding block 51. The top end of the side wall of the heat insulation box 2 is provided with the sliding groove 22 which cooperates with the sliding block 51. The lower surface of the first heat insulation cover plate 3 and the second heat insulation cover plate 4 is provided with the second accommodating groove 31 and the third accommodating groove 41 which cooperate with the heat insulation connecting cover plate 5. The first elastic sealing gasket 32 and the second elastic sealing gasket 42 are arranged on the inner wall of the second accommodating groove 31 and the third accommodating groove 41 respectively. The cooperation of the sliding groove 22 and the sliding block 51 makes the heat insulation connecting cover plate 5 in more sealing contact with the top of the heat insulation box 2 to improve the heat insulation effect.

[0030] When the application is used:

[0031] The battery of the bus is arranged on the base 1 and in the heat insulation box 2. When the battery needs to be heat insulated in cold winter, the heat insulation connecting cover plate 5 is pulled to seal the top of the heat insulation box 2 to realize the heat insulation of the battery. In summer, the heat insulation connecting cover plate 5 is pulled again to expose the opening of the top of the heat insulation box 2 to facilitate the heat dissipation of the battery. The wires of the bus can pass through the threading groove 21 to be connected with the circuit. The cooperation of the heat insulation connecting cover plate 5, the first heat insulation cover plate 3 and the second heat insulation cover plate 4 can open or seal the top of the heat insulation box 2 according to the actual temperature. In cold winter, the battery can be heat insulated. In summer, the battery can be effectively heat dissipated. The heat insulation box 2 can be changed according to the actual situation to improve the practicability of the heat insulation box 2. The baffle 7 can change the size of the threading groove 21. After the wires pass through the threading groove 21, the excess part of the threading groove 21 can be sealed to prevent the external air from entering when the battery needs to be heat insulated to improve the heat insulation effect.
