[0022] The technical solution of the present invention is further specifically described below through embodiments and in conjunction with the accompanying drawings.

[0023] In order to clearly describe the technical solution, the following definitions are made: Figure 1 The front and rear sides of the carriage 21 are shown. Figures 1 to 6 A mobile charging vehicle battery cabinet, the charging vehicle includes a carriage 21, the battery cabinet includes a plurality of cabinets 11 arranged in the carriage 21, a plurality of batteries 31 are arranged in the cabinet 11 from top to bottom, from the front side to the rear side of the carriage 21, the cabinets 11 are arranged in sequence and abut against each other, thereby increasing the stability between the cabinets 11, the cabinet 11 includes a base 111, a cabinet top 112, a side plate 113 and a back plate 114, the number of side plates 113 of each cabinet 11 is two, the back plate 114 is arranged between the side plates 113 and between the cabinet top 112 and the base 111, and an opening is formed between the base 111, the cabinet top 112, the side plates 113 and the back plate 114, facing away from the back plate 114 The side panel 113 comprises a main board 1131, a plurality of receiving grooves 1131a are arranged on the inner side of the main board 1131, a limiting groove 1131b is arranged at the bottom of the receiving groove 1131a, a rotating shaft 1131c is fixedly connected in the receiving groove 1131a, a partition block 1131d is rotatably connected to the rotating shaft 1131c, the partition block 1131d extends horizontally, one end of the partition block 1131d is located outside the receiving groove 1131a, and the other end of the partition block 1131d abuts against the upper side wall of the limiting groove 1131b, and the partition blocks 1131d are arranged in sequence from top to bottom on the inner side of the main board 1131 and are spaced apart from the battery 31.

[0024] When installing the cabinet 11, first install the base 111 on the bottom of the carriage 21, then install the side panels 113 and the back panel 114 to the base 111, and finally install the cabinet top 112. The number of parts that need to be installed is small, and the installation speed is greatly accelerated. Among them, the side panel 113 comes with a partition block 1131d, that is, the partition block 1131d has been pre-installed on the main board 1131 before leaving the factory, and there is no need to install the partition blocks 1131d one by one on site. The partition block 1131d serves to separate the batteries 31. When the side panel 113 is not installed, the partition block 1131d is located in the accommodating groove 1131a, which reduces the volume of the side panel 113 and facilitates storage. When the cabinet 11 is installed, the partition block 1131d extends horizontally, and one end of the partition block 1131d abuts against the upper side wall of the limit groove 1131b. When the battery 31 is placed in the accommodating space, the partition block 1131d supports the lower side of the battery 31, see Figure 2 and Figure 3 .

[0025] A heat dissipation air duct 115 is formed between the batteries 31, and sealing flanges 311 are fixedly connected to the upper and lower sides of one end of the battery 31 away from the back plate 114. The sealing flanges 311 of the upper and lower adjacent batteries 31 abut against each other to close the opening of the accommodating space. The main board 1131 is provided with an air hole 1131e connected to the heat dissipation air duct 115, and the heat dissipation air ducts 115 of two adjacent cabinets 11 are connected through the air hole 1131e. The front end of the carriage 21 is provided with an air inlet 211, and the rear end of the carriage 21 is provided with an air outlet 212. The air hole 1131e closest to the front side of the carriage 21 is connected to the air inlet 211, and the air hole 1131e closest to the rear side of the carriage 21 is connected to the air outlet 212.

[0026] When the battery 31 generates heat during use, the air in the heat dissipation duct 115 becomes hot, and the sealing flange 311 prevents the heat in the accommodating space from being discharged into the car body 21. The air hole 1131e connects the heat dissipation duct 115 of the adjacent cabinet 11, and the air from the air inlet 211 passes through the heat dissipation duct 115 of the cabinet 11 in turn and leaves from the air outlet 212, thereby discharging the heat in the heat dissipation duct 115 into the atmosphere, thereby reducing the temperature of the battery 31.

[0027] The width of the receiving groove 1131a is c, the width of the partition block 1131d is d, c is smaller than d, a vent 1131f is formed between the receiving groove 1131a and the partition block 1131d, and the air hole 1131e is connected to the heat dissipation air channel 115 through the vent 1131f. Figure 5 and Figure 6 The air hole 1131e is connected to the heat dissipation air channel 115 through the limiting groove 1131b, the accommodating groove 1131a, the air vent 1131f, and the heat dissipation air channel 115, thereby increasing the compactness of the structure.

[0028] See also Figure 3, the shaft 1131c passes through the partition block 1131d, the distance between the upper side of the partition block 1131d and the axis of the shaft 1131c is a, the distance between the lower side of the partition block 1131d and the axis of the shaft 1131c is b, and a is smaller than b. Through the above arrangement, when the cabinet 11 is installed, the side panel 113 is in a horizontal state when it is not installed, and the partition block 1131d is hidden in the receiving groove 1131a. When installing the side panel 113, the side panel 113 is vertically installed on the base 111, see Figure 6 At this time, the center of gravity of the partition block 1131d is offset from the axis of the rotating shaft 1131c. Specifically, the center of gravity of the partition block 1131d is located on the side of the notch of the rotating shaft 1131c close to the accommodating groove 1131a. Under the action of gravity, the partition block 1131d will automatically rotate to a horizontal state, that is, automatically abut against the upper side wall of the limiting groove 1131b, and there is no need to manually rotate the partition block 1131d.

[0029] The distance from the rotating shaft 1131c to the notch of the receiving groove 1131a is e, and b is equal to e. That is, when the partition block 1131d is located in the receiving groove 1131a, the side of the partition block 1131d away from the main board 1131 is flush with the notch of the receiving groove 1131a, see Figure 6 .

[0030] The main board 1131 on the front side closest to the car 21 is fixedly connected to the first wind collecting hood 1131g, and the main board 1131 on the rear side closest to the car 21 is fixedly connected to the second wind collecting hood 1131h. The air inlet 211 is arranged on the upper side of the car 21, and the air inlet 211 is connected to the first wind collecting hood 1131g, and the air outlet 212 is connected to the second wind collecting hood 1131h. An air guide plate 213 is arranged on the upper side of the air inlet 211. From the front side to the rear side of the car 21, the air guide plates 213 are tilted downward and are rotatably connected to the car 21. The car 21 is provided with a driving device 214 for driving the air guide plates 213 to rotate.

[0031] The present application includes two heat dissipation modes: passive heat dissipation and active heat dissipation. In passive heat dissipation, the charging vehicle moves forward. Under the action of the wind guide plate 213, air enters the second wind collecting cover 1131h through the air inlet 211, the first wind collecting cover 1131g, and the heat dissipation air duct 115, and leaves the vehicle 21 from the air outlet 212. When it rains, under the action of the driving device 214, the wind guide plate 213 rotates until the air inlet 211 is covered to prevent rainwater from entering the vehicle 21 from the air inlet 211 and damaging the battery 31.

[0032] The driving device 214 includes a first electric cylinder 2141 fixedly connected to the upper side of the carriage 21, a handle 2131 is fixedly connected to the side of the air guide plate 213 away from the air inlet 211, a connecting rod 2132 is arranged between the handle 2131 and the first electric cylinder 2141, one end of the connecting rod 2132 is hinged to the handle 2131, and the other end of the connecting rod 2132 is hinged to the first electric cylinder 2141.

[0033] The air outlet 212 gradually slopes downward from the inside to the outside of the vehicle compartment 21 , thereby preventing rainwater from entering the vehicle compartment 21 through the air outlet 212 .

[0034] The second air collecting hood 1131h is connected to the air outlet 212 through an air duct 1131j extending horizontally. A second electric cylinder 1131k is arranged in the second air collecting hood 1131h. The second electric cylinder 1131k includes a cylinder body and an output shaft. The cylinder body is fixedly connected to the corresponding main board 1131. The output shaft of the second electric cylinder 1131k faces the air duct 1131j and is fixedly connected to a piston 1131m. The piston 1131m is provided with a plurality of through holes 1131n. A film 1131p is provided on the side of the piston 1131m away from the cylinder body. One end of the film 1131p is connected to the piston 1131m, and the film 1131p covers the side of the through hole 1131n away from the cylinder body.

[0035] In the case of passive heat dissipation, the piston 1131m is located outside the air duct 1131j and inside the second air collecting cover 1131h. Figure 2 At this time, air is circulated between the air duct 1131j and the second air collecting cover 1131h. When the present application is actively cooling, the piston 1131m enters the air duct 1131j and moves back and forth in the air duct 1131j under the action of the second electric cylinder 1131k. Specifically, when the piston 1131m moves toward the rear side of the carriage 21, the piston 1131m discharges the air in the air duct 1131j to the atmosphere. In this process, the film 1131p is close to the piston 1131m, and the air in the second air collecting cover 1131h moves toward the rear side of the carriage 21 and enters the air duct 1131j; when the piston 1131m moves toward the front side of the carriage 21, the air in the air duct 1131j passes through the through hole 1131n and pushes away the film 1131p covering the piston 1131m; in this reciprocating manner, the piston 1131m continuously discharges the air in the second air collecting cover 1131h from the air outlet 212. In this embodiment, the film 1131p functions as a one-way valve.

[0036] The end of the battery 31 away from the back plate 114 is fixedly connected with a fixed flange 312, and the fixed flange 312 is fixedly connected to the side of the main board 1131 away from the back plate through screws.

[0037] The upper side of the cabinet top 112 abuts against the upper inner wall of the vehicle compartment 21 .
