A positioning wheel 205 is fixedly installed on the inner wall corresponding to the motor 204. A winding wheel 206 is fixedly installed on the output shaft of the motor 204. A cable is wound on the winding wheel 206. The cable is connected to the battery compartment. 1 is electrically connected, the winding wheel 206 is rotatably connected with the positioning wheel 205, a circle of equally spaced steel balls 207 are installed on one side of the positioning wheel 205 close to the winding wheel 206, the steel balls 207 can be elastically contracted into the positioning wheel 205, a circle of grooves 208 matching with the steel balls 207 are provided on one side of the winding wheel 206 close to the positioning wheel 205, the steel balls 207 can be stuck into the grooves 208, and a rotatable guide wheel 209 is also installed in the equipment compartment 202, and the cable passes under the guide wheel 209.

[0024] The power supply group 2 also includes a separate power supply component 210 and multiple cleaning components 211. The cleaning component 211 is fixed on the inner wall of the equipment compartment 202. The separate power supply component 210 is stuck on the equipment housing A201 and is connected to the interior of the equipment compartment 202. The end of the cable leaves the positioning wheel 205 and passes through multiple cleaning components 211 and then connects to the separate power supply component 210.

[0025] The motor 204 is integrated with the reducer and can provide the torque required to drive the winding wheel 206 to reel in the cable. The positioning wheel 205 can be used to support the winding wheel 206 and prevent the winding wheel 206 from inertial operation. The steel ball 207 is installed in a movable manner. A plurality of steel ball grooves are provided on one side of the positioning wheel 205 where the steel ball 207 is installed. A spring is provided inside the steel ball 207. The steel ball 207 is compressed and installed in the steel ball groove by a spring. When the steel ball 207 is subjected to external force, it will retract into the positioning wheel 205. The cable is wound around the winding wheel 206 for multiple turns, and the central end is connected to the battery compartment 1 through the main shaft of the winding wheel 206 and the center of the positioning wheel 205.

[0026] like Figure 4 and Fig. 9 The separate power supply component 210 includes a socket strip A2101, a plate frame 2102, an elastic ring 2103 and a protective shell 2104. The side wall of the device housing A201 corresponding to the device compartment 202 is provided with a placement groove 212, the plate frame 2102 is in the placement groove 212, the elastic ring 2103 is fixed on the outer ring of the plate frame 2102, is outside the device housing A201, and is larger than the area of ​​the placement groove 212, the protective shell 2104 is fixed on the side of the plate frame 2102 inside the device compartment 202, the socket strip A2101 is fixed on the side of the plate frame 2102 outside the device compartment 202, and a handle 2105 is installed on the side of the plate frame 2102 outside the device housing A201. When the cable is loosened, the plate frame 2102 can be pulled out of the placement groove 212 by the handle 2105; A spring sleeve 2106 is fixedly installed on one surface of the plate frame 2102 inside the equipment compartment 202. The spring sleeve 2106 passes through the protective shell 2104. A spiral wire 2107 is arranged inside the spring sleeve 2106. One end of the spiral wire 2107 is connected to the cable, and the other end is connected to the socket A2101. Force plates 2108 are fixedly installed at both ends of the spring sleeve 2106. The cable passes through one of the force plates 2108 and is fixed to it, and the other force plate 2108 is fixed to the plate frame 2102.

[0027] Multiple sockets A2101 can be set up, specifically two five-hole sockets, which can not only meet the charging needs of daily small appliances and equipment, but also devices with three-pin plugs can be used when camping, so that multiple devices can be powered at the same time. The plate frame 2102 is the main conductive component, and multiple groups of copper cores are arranged inside it for conduction between the cable and the socket A2101. The elastic ring 2103 is made of rubber material, which can prevent the plate frame 2102 from directly contacting the ground when it falls, and can also play a limiting role when the plate frame 2102 enters the placement slot 212. The protective shell 2104 mainly protects the plate frame 2102 and the connection point between the plate frame 2102 and the cable. The handle 2105 is installed on the plate frame 2102 in a foldable form, which can be unfolded during daily use to facilitate pulling the plate frame 2102 out of the placement slot 212.

[0028] The spring sleeve 2106 is a rubber sleeve with a spring and a deformation sensor integrated inside. When the motor 204 finally reels the cable, the plate frame 2102 will be stuck in the placement slot 212. At this time, the motor 204 continues to run, and the spring sleeve 2106 will be stretched and deformed. At this time, the internal deformation sensor can transmit a signal to the controller, and the controller turns off the motor 204. Since a spiral wire 2107 is arranged inside the spring sleeve 2106, when it is deformed, the connection between the cable and the socket strip A2101 will not be disconnected, and the service life is also extended.

[0029] The cleaning component 211 includes an outer frame 2111, which is fixed in the equipment compartment 202. A movable frame 2112 is provided inside the outer frame 2111. The outer frame 2111 and the movable frame 2112 are connected by a rubber pad 2114. An annular brush 2113 is provided inside the movable frame 2112, and the cable passes through the annular brush 2113.

[0030] The positions of the movable frame 2112 and the outer frame 2111 will change relatively. The annular brush 2113 is a soft brush and can be disassembled and replaced from the inside of the movable frame 2112. The movable brush is used to brush away dust, weeds, debris, etc. on the cables.

[0031] The inner bottom wall of the equipment bin 202 is provided with a plurality of through grooves 213 distributed in a matrix, and the through grooves 213 penetrate downwardly through the equipment casing A201. The inner bottom wall of the equipment bin 202 is suspended, and the bottom outer circle of the equipment casing A201 is lower than the bottom of the equipment bin 202. The rear wall of the equipment casing A201 is provided with exhaust holes 214 penetrating inside and outside. A filter fan 215 is installed on the upper wall of the equipment casing A201 corresponding to the equipment bin 202. The filter fan 215 corresponds to the cleaning component 211 and the through groove 213 at the same time.

[0032] The through groove 213 can not only achieve the effect of dust removal, but also prevent the winding wheel 206 from overheating. The filter fan 215 is a combination of a fan and a filter. When running, it can send external air into the equipment compartment 202 and then discharge it from the through groove 213. If the equipment floor is closed, the circulating air will be discharged from the exhaust hole 214.

[0033] A terminal rack 216 is installed on the rear wall of the equipment housing A201 corresponding to the jumper compartment 203. Two long cables 217 are installed in the jumper compartment 203. The long cables 217 are stacked in the jumper compartment 203. The other ends of the long cables 217 are installed with jumper terminals 218. The jumper terminals 218 are plugged and fixed on the terminal rack 216. Pulling the jumper terminals 218 can pull them out of the terminal rack 216.

[0034] The long cable 217 is installed in a fixed manner. When the jumper operation is not being performed, the jumper compartment 203 can be used to store the long cable 217. If jumper operation is required, the jumper terminal 218 can be pulled out, and the long cable 217 will also be pulled out. It can be stored at any time after use, and the problem of losing the jumper cable in the prior art will not occur.

[0035] The battery compartment 1 includes a device housing B101, a top cover 102 is installed on the top wall of the device housing B101, the top cover 102 is buckled on the upper end of the device housing B101, a plurality of battery clips 103 are fixedly installed on the inner bottom wall of the device housing B101, a plurality of conductive posts 104 are fixed in the battery clips 103, a plurality of batteries 105 are also arranged in the device housing B101, and the batteries 105 can be inserted in the battery clips 103 and connected to the plurality of conductive posts 104.

[0036] The top cover 102 can be removed from the top of the device housing B101, and the top cover 102 can also be connected to the upper end of the device housing B101 in the form of hinges and buckles. When the top cover 102 is closed, the battery 105 is firmly fixed in the battery clip 103, and the battery clip 103 and the battery 105 adopt an interference fit relationship. The bottom of each battery 105 is provided with a cylindrical hole that cooperates with the conductive column 104, and a conductive copper sheet is provided in the cylindrical hole. The power of the battery 105 is conducted through the four conductive columns 104. When the battery 105 is pulled out, the power of this battery 105 is disconnected.

[0037] A plurality of solar panels 106 are fixedly mounted on the top cover 102 .

[0038] Since the area of ​​the solar panel 106 is limited to the size of the battery compartment 1, it can only provide a small amount of electricity when used outdoors. This electricity can be used for lighting equipment on the equipment, or to provide additional power for low-power equipment in the camping site, which can save some energy.

[0039] A socket strip B107 and an operation screen 108 are fixedly mounted on the front of the device housing B101.

[0040] Socket strip B107 is the same as socket strip A2101, and both can provide dual-hole and triple-hole power supply. The operation screen 108 is used to observe various data such as the instantaneous power consumption, voltage and current data, real-time battery capacity, etc. of the entire equipment. A lighting lamp can also be installed on the equipment housing B101, and universal wheels can be installed on the bottom.

[0041] A handle 109 is fixedly mounted on the surfaces of the device housing A201 and the device housing B101 that are away from each other.

[0042] When in use, the vehicle-mounted equipment power supply usage scenario: the device is placed in the trunk as a whole and can be transported at any time. When the vehicle-mounted equipment is powered, the socket A2101 or the socket B107 can be used. Setting the socket A2101 and the socket B107 can increase the number of charging devices and save charging time; Camping power supply usage scenario: When drawing power from the vehicle's external camping equipment, there is no need to move the emergency power supply out of the trunk. You only need to pull the handle 2105, and then pull out the separate power supply assembly 210 as a whole through the cable. In this state, the winding wheel 206 can release the cable. Due to the action of the positioning wheel 205, when pulling the cable, the winding wheel 206 will not rotate excessively to cause the cable to loosen. After reaching the designated position, the camping appliances can use the socket A2101 to draw power. Since the elastic ring 2103 and the protective shell 2104 are installed, the plate frame 2102 can be directly pulled out and thrown on the ground, which increases the convenience of operation, especially for ground equipment to draw power, and the operation is faster. When recycling, the motor 204 needs to rotate, and the winding wheel 206 can reel in the cable. At this time, the annular brush 2113 can remove dust from the outside of the cable, and the filter fan 215 can blow the removed dust away from the equipment compartment 202. The blown dust will first pass through the through groove 213 and then discharged from the exhaust hole 214. When the plate frame 2102 is rolled up and enters the placement groove 212, the spring sleeve 2106 begins to be stretched by force. When the spring sleeve 2106 is deformed, the motor 204 stops rotating. At this time, the winding wheel 206 is fixed by the positioning wheel 205, and the plate frame 2102 will be firmly fixed in the placement groove 212 and will not fall off. If the entire device needs to be moved out of the trunk, since the battery compartment 1 is openable, each individual battery 105 can be taken out. If it is difficult to move the emergency power supply in the actual use scenario, each battery can be taken out separately, and then the emergency power supply can be taken out, and finally assembled again at the use location. The number of modular batteries 105 can be adjusted at will according to the use scenario. A solar panel 106 is set, and the emergency power supply can be placed outside to charge using solar energy. When camping, a small amount of electricity can be collected for lighting the equipment at night. Emergency power supply scenario: In emergency use, the two jumper terminals 218 can be pulled out from the terminal frame 216 and then connected to the car battery for emergency power supply. Since the long cable is not long enough, the length can be customized in specific use. If necessary, the entire equipment can be moved to the engine position. When not in use, the long cable 217 and the jumper terminal 218 can be inserted into the terminal frame 216.
