[0022] Further, such as Figure 6 and Figure 7 As shown, the dust removal component 200 includes a piston barrel 201 and an adjusting seat 205; the surface of the piston barrel 201 is connected with an air intake pipe 202 and an air delivery pipe 203, the air intake pipe 202 and the air intake port 112 are connected, the surface of the air delivery pipe 203 is connected with an air bag 204, the surface of the air bag 204 is connected to the bottom of the adjusting seat 205, the surface of the adjusting seat 205 is connected with an exhaust pipe 207, the exhaust pipe 207 and the exhaust port 110 are connected; the adjusting seat 205 is fixedly connected to the charging box 1, the inside of the adjusting seat 205 is slidably connected with a regulating frame 206, and the bottom of the regulating frame 206 is fixedly connected with a return spring 208; a through hole is opened at the bottom of the regulating frame 206; the exhaust pipe 207 is conically set, and the diameter is smaller on the side connected to the exhaust port 110.

[0023] Further, such as Figure 8 As shown, the on-off assembly 300 includes an intelligent control motor 301 and a sliding plate 303. The intelligent control motor 301 is arranged above the battery 6. The output end of the intelligent control motor 301 is fixedly connected to a screw rod 302.

Limiting plates 304 are arranged on both sides of the sliding plate 303.

[0024] like Figure 8 As shown, a temperature measuring power transmission board 61 is arranged above the battery 6, the intelligent control motor 301 and the limit plate 304 are fixed on the surface of the temperature measuring power transmission board 61, and a connector 62 is fixedly arranged on the surface of the temperature measuring power transmission board 61; the battery 6 and the cover 5 are connected to each other through a wire connector 7, one end of the wire connector 7 is clamped on the surface of the sliding plate 303, and the other end of the wire connector 7 is fixed to the surface of the cover 5; the wire connector 7 is slidably connected to the connector 62; an air guide plate 63 is arranged on the surface of the battery 6, and a cooling fan 8 is arranged below the battery 6.

[0025] like Figure 4 As shown, two groups of sliding covers 51 are slidably arranged on the surface of the cover 5, magnetic sheets are arranged on the surfaces of the two groups of sliding covers 51, and a charging panel 52 is arranged on the surface of the sliding covers 51; universal wheels 3 and a push handle 4 are arranged on the surface of the charging box 1.

[0026] According to S4, the scattered dust is removed in time through the dust removal component 200; wherein, when the supporting plate 108 moves upward, it drives the piston plate 113 to slide upward inside the piston barrel 201, and the air intake duct 202 and the air intake port 112 are connected through, and the air intake port 112 is located on the surface of the removal groove 109. Then, the air enters the piston barrel 201 through the surface of the removal groove 109, and the dust above the removal groove 109 is sucked downward to prevent the dust from spreading.

[0027] Working principle: the charging box 1 and the cover 5 are tightly connected by bolts. When the battery 6 needs to be embedded in the charging box 1, the bolts need to be unscrewed to separate the cover 5 and the charging box 1 from each other; the cylinder 101 is started, and the push rod 102 is retracted by the cylinder 101. The push rod 102 indirectly controls the drive shaft 104 through the connector 103 to achieve synchronous displacement. The drive shaft 104 applies pressure to the right with the right side as the reference. At the same time, the scissor-type lifting component 105 is hindered by the lower limit seat 106 on the right side, and finally the scissor-type lifting component 105 moves upward in a scissor-like manner, and then the carrying plate 108 is gradually lifted, so that the embedding operation of the battery 6 becomes more convenient, thereby improving the installation efficiency.

[0028] After the battery 6 is placed on the upper surface of the carrier plate 108, the start cylinder 101 resets and controls the drive shaft 104 to drive the left end of the scissor-type lifting component 105 to the left, so that the carrier plate 108 moves downward, and the battery 6 is embedded in the interior of the charging box 1, and then the cover 5 is reinstalled on the upper surface of the charging box 1 through bolts, so as to protect the battery 6; at this time, the intelligent control motor 301 can be controlled to start, and the output end of the intelligent control motor 301 drives the screw rod 302 to rotate, and the screw rod 302 rotates to control the sliding plate 303 to slide to the right on the surface of the temperature measurement and transmission plate 61, and the wire connector 7 is clamped on the surface of the sliding plate 303, and the sliding plate 303 drives the wire connector 7 to be inserted into the connector 62, so as to complete the power transmission between the battery 6 and the cover 5, and then the charging panel 52 is exposed by sliding the sliding cover 51 to both sides of the cover 5, so as to carry out related charging and power transmission operations; At the same time, the cooling fan 8 is turned on, and the diversion generated by the cooling fan 8 is guided by the wind guide plate 63, so that the wind absorbs the heat generated by the battery 6 during operation, and then guides it to be stably led out through the vent 2, thereby improving the heat dissipation effect; at the same time, the wind guide plate 63 is set in an arc shape. When the wind flow is led out through the arc surface, the wind will be gathered in a small range and then discharged faster, thereby improving the heat dissipation efficiency; the wind guide plate 63 will properly block the upward hot air to prevent it from blowing to the surface of the temperature measuring transmission board 61, thereby avoiding errors in the monitoring of the surface temperature of the battery 6 by the temperature measuring transmission board 61, thereby improving the protection of the battery 6.

[0029] When the battery 6 needs to be maintained or replaced, repeat the above steps of embedding the battery 6 into the charging box 1 to complete the quick maintenance and replacement operation; During this process, the carrying plate 108 drives the L-shaped support frame 117 to move upward through the enclosure 116. At the same time, the friction wheel 119 rubs against the inner surface of the charging box 1, thereby driving the cleaning brush 118 to rotate and sweep away the dust adsorbed on the inner surface of the vent 2, thereby preventing the vent 2 from being blocked and causing the heat of the battery 6 to be unable to be stably removed, thereby increasing the risk of explosion or damage to the battery 6. At the same time, the piston plate 113 slides upward inside the piston barrel 201, and the piston barrel 201 is connected with the air intake port 112 through the air intake pipe 202. A one-way valve is arranged inside the air intake pipe 202 and the air supply pipe 203. At this time, the air intake pipe 202 is in a connected state, and the air supply pipe 203 is in a closed state; the air is sucked into the piston barrel 201 from above the removal groove 109, and the dust floating above the removal groove 109 can be attracted downward to prevent the swept dust from flying around and causing secondary pollution to the inside of the charging box 1. A filter is arranged inside the air intake pipe 202 to prevent dust from entering the inside of the piston barrel 201.

[0030] When the carrier plate 108 is reset downward, the cleaning brush 118 is reversed to clean the dust from the vent 2 again, and when the piston plate 113 slides downward over the piston barrel 201, the air can be squeezed into the air bag 204 through the air delivery pipe 203, causing the air bag 204 to expand and temporarily store the gas. At this time, the one-way valve inside the air intake pipe 202 is closed; When the supporting plate 108 slides downward and is completely reset, the regulating frame 206 is squeezed downward, thereby moving the through hole on the surface of the regulating frame 206 to the same level as the airbag 204, so that the gas inside the airbag 204 can flow normally through the exhaust duct 207, and then the gas is introduced into the exhaust port 110 through the exhaust duct 207, so that the dust is blown from the left side of the removal groove 109 to the right side. At this time, the removal groove 109 corresponds to the position of the empty groove opened on the surface of the charging box 1, so that the dust is discharged from the interior of the charging box 1, and the dust is removed in time, which effectively improves the cleanliness of the inside of the charging box 1, thereby making the battery 6 more stable during operation.

[0031] When the temperature measuring and power transmission board 61 detects that the temperature on the surface of the battery 6 rises abnormally, the intelligent control motor 301 is immediately started to reverse, and the screw rod 302 reverses to pull the wire connector 7 out of the connector 62 through the sliding plate 303, disconnecting the power transmission between the battery 6 and the cover 5, thereby improving the protection effect of the battery 6.

[0032] Repeat the above steps of embedding the battery 6 into the charging box 1 to complete the rapid maintenance and replacement of the abnormal battery 6.
