The lifting mechanism 200 is fixedly disposed on the energy storage housing 110, and is configured to fix the energy storage housing 110 to the guide rod 256, and drive the energy storage housing 110 to move along an axis of the guide rod 256.

Referring to fig. 8 or 9, in one embodiment, the lifting mechanism 200 includes a lifting housing 210 and an embracing mechanism 230. The lifting housing 210 is provided with an annular channel 255 that extends through the lifting housing 210. The annular channel 255 is adapted to pass through the guide rod 256. The embracing mechanism 230 is disposed in the lifting housing 210 and surrounds the annular channel 255, so as to change the size of the annular channel 255. The embracing mechanism 230 may be made of a material having flexibility and elasticity.

In one embodiment, the lifting mechanism 200 is coupled to the energy storage housing 110. The lifting mechanism 200 may secure the solar energy storage device 10 to a guide rod 256. The lifting mechanism 200 may include a lifting housing 210. A main rod hole matched with the guide rod 256 in shape is reserved in the middle of the lifting shell 210. The main rod hole may be the annular channel 255 to mount the solar energy storage device 10 to the guide rod 256.

referring to fig. 9 or fig. 10, in an embodiment, the lifting housing 210 includes a first sub-housing 211 and a second sub-housing 212, and the first sub-housing 210 and the second sub-housing 212 are spliced to form the annular channel 255. The embracing mechanism 230 is fixed to the first sub-housing 211.

Referring to fig. 9, in one embodiment, the lifting mechanism 200 includes an adjusting screw 224. The clasping mechanism 230 includes a fixed end 221 and a free end 222. The fixing end 221 is fixedly disposed on the first sub-housing 211. The free end 222 has a threaded hole 223. The second sub-housing 212 has a through hole 213, and the adjusting screw 224 passes through the through hole 213 and the screw hole 223 to connect the second sub-housing 212 and the embracing mechanism 230. And the size of the diameter of the annular channel 255 can be varied by the adjustment screw 224. During screwing of adjusting screw 224 into threaded hole 223, ring structure 230 may be bent toward annular channel 255, thereby reducing the diameter of annular channel 255, and thereby securing solar energy storage device 10 to guide rod 256.

referring to fig. 10, in one embodiment, the first sub-housing 211 has a fixing hole 214. The fixing end 221 is fixed to the first sub-housing 211 by a fixing screw 215 engaged with the fixing hole 214. The fixing end 221 may be provided with a through slot, and the fixing screw 215 passes through the through slot and the fixing hole 214 to fix the embracing mechanism 230 to the first sub-housing 211.

referring again to fig. 9, in one embodiment, the second sub-housing 212 has a groove 219. The through hole 213 is disposed at the bottom of the groove 219. The adjustment screw 224 may be inserted into the groove 219, and thus the adjustment screw 224 may be prevented from being exposed to the surfaces of the first sub-housing 211 and the second sub-housing 212.

Referring to fig. 7 or 8 again, in an embodiment, the lifting mechanism 200 further includes a shielding cover 240, and the shielding cover 240 is fastened to a side of the lifting housing 210 close to the free end 222.

The screw hole 223 can be attached to the free end 222 of the embracing mechanism 230 by injection molding.

In one embodiment, the first sub-housing 211 and the second sub-housing 212 are further provided with connection screw holes 218, respectively. The connection screw hole 218 extends from the fixed end 221 toward the free end 222. The lifting housing 210 and the energy storage housing 110 are connected by a connecting screw 216.

The embracing mechanism 230 may be two. The clasping mechanism 230 is curved at the annular channel 255. The two embracing means 230 enclose the annular channel 255.

Referring to fig. 9, in the above embodiment, during the process of screwing the adjusting screw 224 into the screw hole 223, the adjusting screw may apply pressure to the surrounding mechanism 230, so that the surrounding mechanism 230 embraces the guide rod 256. The pressure applied to the clasping mechanism 230 depends on the length of the adjustment screw 224 that is threaded. That is, the longer the adjustment screw 224 screwed into the screw hole 223 is, the greater the pressure applied to the embracing mechanism 230 by the adjustment screw 224 is, and the more the embracing mechanism 230 embraces the guide rod 256. When the adjusting screw 224 is screwed out of the screw hole 223, the pressure applied to the embracing mechanism 230 is reduced or even eliminated, and the pressure between the embracing mechanism 230 and the guide rod 256 is reduced or even eliminated. The embracing mechanism 230 is separated from the guide rod 256. After the embracing mechanism 230 is separated from the guide rod 256, the lifting mechanism 200 can be lifted along the guide rod 256 or rotated around the guide rod 256. Therefore, the height of the solar energy storage device 10 can be adjusted by adjusting the adjusting screws, and the solar energy storage device is easy to operate and convenient to use.

In one embodiment, the clasping mechanism 230 comprises a free end 222 and a fixed end 221. Referring to fig. 11-13, the lifting mechanism 200 further includes a hoop rotating shaft 251, a torsion spring 252 and an unlocking button 254. Referring to fig. 13, the hoop rotating shaft 251 is disposed on the first sub-housing 211. The fixed end 221 is sleeved on the hoop rotating shaft 251. The torsion spring 252 is sleeved on the surrounding rotating shaft 251, and two clamping ends of the torsion spring 252 respectively abut against the surrounding mechanism 230 and the first sub-housing 211. The unlocking button 254 abuts against the free end 222. The unlock button 254 may change the size of the annular channel 255 by squeezing the free end 222.

Referring to fig. 13, in the present embodiment, two engaging ends of the torsion spring 252 respectively abut against the surrounding mechanism 230 and the first sub-housing 211, so that the surrounding mechanism 230 tends to bend toward the annular channel 255, and further can tightly hold the guide rod 256. When the unlocking button 254 abuts against the free end 222, the embracing mechanism 230 may be moved away from the annular channel 255, and the guide rod 256 may be released.

In one embodiment, a gap may be left between the surrounding mechanism 230 and the inner wall of the first sub-housing 212 to facilitate the separation of the surrounding mechanism 230 from the guide rod 256. The curved portion of the embracing means 230 may form one side of the inner wall of the annular channel 255. The second sub-housing 212 may constitute the other side inner wall. The curved portion of the embracing mechanism 230 and the curved portion of the inner wall of the second sub-housing 212 enclose the annular channel 255, so that the energy storage housing 110 can be mounted on the guide rod 256.

In the above embodiment, the second sub-housing 212 and the first sub-housing 211 may be fixed to the energy storage housing 110 by the connection screw 216. The second sub-housing 212 can be fixed and attached to the first sub-housing 211 through a fixing screw 215, so that the curved portion of the surrounding mechanism 230 and the curved portion of the inner wall of the second sub-housing 212 surround to form the annular channel 255, and the second sub-housing 212 and the first sub-housing 211 are attached to form a complete connection body.

In one embodiment, the free end 222 is provided with an abutment inclined surface 225. When the unlocking button 254 pushes the embracing mechanism 230 along the abutment inclined surface 225, the embracing mechanism 230 expands the diameter of the annular passage 255 against the elastic force of the torsion spring 252. It will be appreciated that the abutment inclined surface 225 is inclined in a direction away from the annular channel 255, so that when the unlocking button 254 is moved in a vertical direction towards the abutment inclined surface 225, the clasping mechanism 230 is moved in a direction away from the annular channel 255, thereby enlarging the diameter of the annular channel 255.

In one embodiment, the first sub-housing 211 defines a receiving groove 217, and the unlocking button 254 passes through the receiving groove 217 to abut against the abutting inclined surface 225. The receiving groove 217 has a certain depth, so that the unlocking button 254 is prevented from being directly exposed to the surface of the first sub-housing 211, and the unlocking button 254 can be protected from being damaged.

Referring again to fig. 11, in one embodiment, the lifting mechanism 200 further includes an unlocking spring 253. One end of the unlocking spring 253 abuts against the bottom of the accommodating groove 217, and the other end abuts against the unlocking button 254. When the unlock button 254 is pressed, the unlock spring 253 is compressed, the diameter of the annular passage 255 is increased, and the friction force between the lift mechanism 200 and the guide rod 256 is reduced, so that the lift mechanism 200 can be moved.

Referring to fig. 11 and 12, in one embodiment, the bottom of the receiving groove 217 has a hole with a size matching the size of the unlocking button 254. An annular protrusion is formed around the hole, the unlocking spring 253 is disposed outside the annular protrusion, and one end of the unlocking button 254 may be fixed to the unlocking spring 253.

In the above embodiment, when the unlocking button is pressed, the embracing mechanism 230 may be pressed to deform, and the unlocking spring 253 is compressed to drive the embracing mechanism 230 to separate from the guide rod 256. After the embracing mechanism 230 is separated from the guide rod 256, the lifting mechanism 200 can be lifted along the guide rod 256 or rotated around the guide rod 256. When the release button 254 is released, the spring force of the release button 254 pushes the release button 254 to return to the original position. Meanwhile, the embracing mechanism 230 recovers its shape under the action of the unlocking spring 253, and is attached to the guide rod 256 again, so that the lifting mechanism 200 is fixed to the guide rod 256. By pressing the unlocking spring 254, the height of the lifting mechanism 200, that is, the height of the solar energy storage device 10, can be adjusted, which is convenient to use.

In one embodiment, the fixed end 221 may be rotatably disposed to the torsion spring 252. When the unlocking button 254 presses the embracing mechanism 230 to deform, the embracing mechanism 230 is separated from the guide rod 256. When the unlocking button 254 is released, the elastic force of the torsion spring 252 pushes the embracing mechanism 230 to rotate around the torsion spring 252 and attach to the guide rod 256, so that the lifting mechanism 200 is fixed to the guide rod 256. By pressing the unlocking button 254, the torsion spring 252 can be adjusted by the embracing mechanism 230, and the size of the annular channel 255 can be changed, so that the height of the lifting mechanism 200 can be adjusted, and the use by a user is facilitated.

Referring again to fig. 12, in one embodiment, the lifting mechanism 200 further includes a rubber rub strip 260. The rubber friction strip 260 may be attached to the bent portion of the embracing mechanism 230 and the bent portion of the inner wall of the first sub-housing 211, i.e., the inner surface of the main rod hole. When the lifting mechanism 200 is mounted on the guide rod 256, the rubber rubbing strip 260 directly contacts the guide rod 256, and thus the friction between the annular channel 255 and the guide rod 256 can be increased. Therefore, the lifting mechanism 200 is more stable when being fixed on the guide rod 256, and is prevented from sliding off.

In one embodiment, the solar energy storage device 10 further comprises a communication control component 160. The communication control component 160 is disposed inside the energy storage housing 110 and electrically connected to the energy storage battery 150. The communication control assembly 160 includes a communication control board 161. Referring to fig. 14, the communication control board 161 is disposed on a surface of the liquid-cooled heat sink 310 away from the energy storage battery 150.

In one embodiment, the communications control assembly 160 further includes a control panel bracket 162.

The charging head 132 is electrically connected to the energy storage battery 150 through the USB cable 180 and the communication control board 161. The other end of the detection board 171 is electrically connected to the communication control board 161. Therefore, the communication control unit 160, the USB cable 180, the charging head 132, the male and female terminals of the connector 172, and the detection board 171 constitute a closed loop. The energy storage battery 150 may be controlled to transmit a pulse signal through the communication control component 160. The pulse signal reaches the pickup plate 171 through the USB cable 180 and the charging head 132, and the pickup plate 171 may detect the integrity of the received pulse signal to determine the integrity of the USB cable 180. When the pulse signal received by the detection board 171 is incomplete, the detection board 171 determines that the USB cable 180 is failed, and transmits the failure information to the communication control unit 160. In one embodiment, the communication control board 161 may also upload information about whether the USB cable 180 is intact to the cloud server 165.

The user can scan the two-dimensional code 163 by using the user terminal APP167, thereby controlling the communication control board 161 to transmit a pulse signal through the antenna 164. The pulse signal may control the charging head 132 to unlock and eject from the charging head slot 131, so that a user may use the device to charge. After the user returns the charging head 132, the detection component 170 detects that the charging head 132 has been returned, and reports the information to the communication control board 161.

The cloud server 165 further can deduct fees according to the charging duration through the client APP 167.

referring to fig. 17 and 18, in an embodiment, the solar energy storage device 10 includes a driving device 120, and at least one charging plug device 130, where the charging plug device 130 is disposed on the energy storage housing 110. Each of the charging plug devices 130 includes a driving assembly 121, a transmission member 133, an elastic member 134, and a cam 122, in addition to the charging head slot 131 and the charging head 132 as described above. The cam 122 is fixedly disposed on the driving assembly 121. The driving assembly 121 is in transmission connection with the driving device 120. The transmission member 133 is disposed on the energy storage housing 110. One end of the transmission member 133 is engaged with the cam working surface 123 of the cam 122, and the other end thereof is in contact with the charging head 132, so that the charging head 132 can be limited in the charging head slot 131. One end of the elastic member 134 abuts against the energy storage housing 110, and the other end of the elastic member 134 abuts against the transmission member 133. When the transmission member 133 drives the cam 122 to rotate through the cam working surface 123, the cam 122 compresses the elastic member 134, and the elastic member 134 releases the charging head 132.

When the force of the driving unit 121 on the transmission member 133 is smaller than the force of the elastic member 134 on the transmission member 133, the elastic member 134 limits the charging head 132 to the charging head slot 131 through the transmission member 133, and when the force of the driving unit 121 on the transmission member 133 is larger than the force of the elastic member 134 on the transmission member 133, the driving unit 121 compresses the elastic member 134 through the transmission member 133, and the transmission member 133 releases the charging head 132.

Referring to fig. 18 and 19, in one embodiment, the driving assembly 121 is a driving shaft. The driving means 120 may be a stepping motor. The stepping motor can be called as a pulse motor, and is an electromagnet capable of freely rotating based on the electromagnet principle. The stepping motor can generate electromagnetic torque by means of the change of air gap permeance, convert an electric pulse signal into angular displacement of the driving shaft 121, and drive the driving shaft 121 to rotate. The energy storage battery 150 may supply power to the stepper motor. The cam 122 is fixedly provided to the drive shaft 121. The stepping motor may control the rotation of the cam 122 through the driving shaft 121. The cam face 123 of the cam 122 may abut one end of the transmission member 133. The charging head 132 can be inserted into and removed from the charging head slot 131.

Referring to fig. 19 again, in the above embodiment, after the charging head 132 is inserted into the charging head slot 131, one end of the elastic member 134 may press the transmission member 133. The transmission member 133 moves toward the opening of the charging head slot 131. An end of the transmission member 133 away from the elastic member 134 may catch an end of the charging head 132 away from the bottom of the charging head slot 131, so that the charging head 132 may be prevented from leaving the charging head slot 131. When the cam 122 rotates so that the cam working surface 123 contacts with one end of the transmission member 133 and abuts against the transmission member 133, the transmission member 133 may compress the elastic member 134. At this time, the driving member 133 releases the charging head 132. The charging head 132 may be separated from the charging head slot 131.

In one embodiment, the energy storage battery 150 may transmit a pulse signal to the driving device 120 through the communication control component 160. After receiving the pulse signal, the driving device 120 drives the driving shaft 121 to rotate clockwise. The rotation speed and the rotation angle of the drive shaft 121 depend on the frequency and the number of pulses of the pulse signal. The driving shaft 121 may rotate the cam 122 clockwise. The cam 122 presses one end of the transmission member 133, so that the transmission member 133 moves to a side close to the inner wall 110 of the energy storage housing, and further compresses the elastic member 134. The other end of the transmission member 133 is separated from the charging head 132 so that the charging head 132 can be taken out. Thus, the unlocking action of the charging head 132 is achieved. After the pulse signal passes, the driving device 120 loses power, and drives the driving shaft 121 to rotate counterclockwise to return to the initial position. The driving shaft 121 no longer presses the first end portion, so that the transmission member 133 releases the elastic member 134, and the elastic member 134 pushes the transmission member 133 again.

The transmission member 133 moves toward the opening of the charging head slot 131 by the pushing force of the elastic member 134. When the elastic member 134 returns to the equilibrium position, one end of the transmission member 133 is located in the charging head slot 131. When the charging head 132 is inserted into the charging head slot 131, the ends of the charging head 132 and the driving member 133 are pressed, so that the charging head 132 is locked in the charging head slot 131.

In one embodiment, the cam 122 defines a slot in the middle thereof. The aperture groove matches the drive shaft 121. The driving shaft 121 may be fitted into the hole groove, thereby fixing the cam 122 to the driving shaft 121.

In one embodiment, the cam 122 may include a protrusion. The transmission member 133 may include a first end and a second end. Said projection abuts against a first end of said transmission piece 133. When the stepping motor is powered to drive the driving shaft 121 and the cam 122 to rotate clockwise, the protrusion may press the first end portion. Thereby driving the transmission member 133 to move toward a side close to the inner wall of the energy storage housing 110, so that the transmission member 133 and the charging head 132 are separated. In the above embodiment, the first end portion may include a ramp surface that cooperates with the protrusion. The protrusion is arranged on the slope surface, so that the protrusion extrudes the first end part.

In one embodiment, the second end and the contact portion of the charging head 132 may be a male and a female mating with each other. The female button may be disposed at an end of the charging head 132, and the male button may be disposed at the second end. The contact surfaces of the male buckle and the female buckle can be parallel to each other and matched with each other. When the charging head 132 is inserted into the charging head slot 131, the female buckle slides along the contact surface and then hooks the male buckle, so that the charging head 132 is inserted into and locked to the charging head slot 131.

In one embodiment, the carriage rail 135 and the transmission member 133 surround to form an elastic member receiving cavity 144. The elastic member 134 is disposed in the elastic member receiving cavity 144. The position of the resilient member 134 may be defined by the resilient member receiving cavity 144.

In one embodiment, the transmission member 133 may have an E-shaped cross-section. The upper portion of the E-drive 133 may be the first end portion. The middle portion of the E-shaped transmission member 133 serves as a guide post for the elastic member 134 to fix the elastic member 134. The end of the lower portion of the E-shaped transmission member 133 near the charging head slot 131 may be the second end, i.e., the male buckle.

In one embodiment, the charging plug device 130 further includes a bracket rail 135. The bracket rail 135 is disposed on an inner wall of the energy storage housing 110. The transmission member 133 includes a sliding portion 136, and the cam 122 rotates to move the sliding portion 136 along the rack rail 135 to change the size of the outlet of the charging head slot 131.

The locking device also includes a carriage rail 135. The bracket rail 135 is fixedly attached to the inner wall of the energy storage housing 110. The side of the elastic member 134 remote from the E-shaped transmission member 133 may be fixed to the bracket rail 135. The rack rail 135 may include an upper rail and a lower rail, and the E-shaped transmission member 133 is fitted between the two rails. The upper and lower portions of the E-shaped transmission member 133 are in parallel contact with the two guide rails, respectively. The guide rail can limit the transmission piece 133 to move left and right in the horizontal direction, so that the male buckle and the female buckle can be hooked conveniently. The sliding portion 136 may be disposed at a lower portion of the E-shaped transmission member 133. The sliding portion 136 can slide on the surface of the bracket rail 135.

In one embodiment, one end of the sliding portion 136 is provided with a blocking surface 137. The charging head is provided with an engaging surface 138, and the blocking surface 137 limits the charging head 132 to the charging head slot 131 through the engaging surface 138. When the transmission member 133 approaches the opening of the charging head slot 131, the blocking surface 137 blocks the engaging surface 138, so that the charging head 132 is confined in the charging head slot 131.

In one embodiment, when the charging head 132 is fitted into the charging head slot 131, the male end of the connector (Pogo Pin)172 is located in the groove and contacts and presses the female end of the connector 172 on the charging head 132, and the elastic body of the female end of the connector 172 is compressed to generate elastic potential energy.

When the user uses the charging head 131, the user can scan the two-dimensional code (163) by using the user side APP167, so that the antenna 164 controls the communication control board (161) to transmit a pulse signal. After receiving the pulse signal, the driving device 120 drives the driving shaft 121 and the cam 122 to rotate clockwise. The cam 122 presses one end of the transmission member 133, so that the transmission member 133 moves to a side close to the inner wall 110 of the energy storage housing, and further compresses the elastic member 134. The other end of the transmission member 133 is separated from the charging head 132. When the other end of the transmission member 133 is separated from the charging head 132, the elastic body at the female end of the connector 172 tends to restore its original state to generate an elastic force, and the elastic force acts on the male end of the connector 172, so that the female end of the connector 172 is ejected, that is, the charging head 132 is ejected under the interaction between the male end and the female end of the connector 172, so that the charging head 132 is conveniently taken out for use. Therefore, the user can unlock the charging head 132 by scanning the two-dimensional code 163, so that the charging head 132 is ejected from the charging slot 131, which is convenient, fast and convenient to use.

After the pulse signal passes, the electromagnet 140 loses power, and the internal magnetic field disappears. The movable shaft 142 moves upward back to the initial position. The movable shaft 142 no longer presses the transmission member 133, so that the transmission member 133 releases the elastic member 134, and the elastic member 134 pushes the transmission member 133 again. The transmission member 133 moves toward the charging head slot 131 by the pushing force of the elastic member 134. When the elastic member 134 returns to the equilibrium position, the transmission member 133 restrains the charging head 132 in the charging head slot 131.

When the charging head 132 is inserted into the charging head slot 131, the contact portion between the charging head 132 and the transmission member 132 is pressed, and the transmission member 133 is pushed to compress the elastic member 134. The contact portions of the charging head 132 and the driving member 133 are engaged together, so that the charging head 132 is engaged in the charging head slot 131. At the same time, the male end of the connector 172 is compressed again by contact with the female end of the connector 172. At the same time, the hall element 173 of the detection plate 171 detects the magnetic field of the detection magnet 174. The detection board 171 sends a feedback signal to the communication control board 161 to indicate that the charging head 132 has returned. The communication control board (161) receives the feedback signal and reports the feedback signal to the cloud server 165 through the antenna (164). The cloud server 165 further can deduct fees according to the charging duration through the client APP 167.

In the above embodiment, the charging plug device 130 may further include a bracket rail 135, the transmission member 135 includes a sliding portion 136, one end of the sliding portion 136 is provided with a blocking surface 137, and the charging head 132 is provided with an engaging surface 138. The rack guide rail and the transmission member 133 surround to form a structure such as an elastic member accommodating cavity 144, and the specific structural form may be the same as or similar to that of the foregoing embodiment, and will not be described herein again.

Referring to fig. 21 again, in an embodiment, the solar energy storage device 10 may include three charging heads 132, and correspondingly, the energy storage housing 110 may include three charging head slots 131. Three charging head slots 131 are arranged side by side in the energy storage housing 110. The electromagnets 140 and the movable shaft 142 may also be three sets, and are disposed in the accommodating case 143. The three charging heads 132 and the three charging head slots 131 can be used independently.

referring again to fig. 1, in one embodiment, the solar energy storage device 10 further includes a winding mechanism 400. The wire winding mechanism 400 is disposed inside the energy storage housing 110 and is used for receiving the USB wire 180. Further, the winding mechanism 400 may be fitted inside the second energy storage sub-housing 112. Referring to fig. 22, the winding mechanism 400 includes a winding upper case 410, a winding lower case 411, a spiral spring 420, a winding wheel 430, a rotating conductive plate 440, and a fixed conductive plate 441. The winding wheel 430 may be disposed at the winding line lower case 411. The winding lower shell 411 has a central shaft fixed thereon, and the winding wheel 430 is sleeved on the central shaft. The connection part of the winding wheel 430 and the central shaft forms a groove of the clockwork spring 420. The spring 420 can be arranged in the groove of the spring 420, one end of the spring is connected with the central shaft in a clamped mode, and the other end of the spring is connected with the winding wheel 430 in a clamped mode. The winding wheel 430 can rotate the central shaft by the spring 420.

Referring to fig. 23, the edge of the winding wheel 430 has two parallel upper and lower portions, forming a winding groove. The USB cable 180 may be wound around the winding slot. When the winding wheel 430 rotates around the central shaft, the USB cable is driven to extend or retract. Specifically, when the user stretches the USB wire 180 using the charging head 132, the winding wheel 430 rotates to compress the clockwork spring 420, generating an elastic force. When the user does not stretch, the external force disappears, and the spiral spring 420 tends to restore the shape, so as to drive the winding wheel 430 to rotate, and the automatic retraction of the USB cable 180 is realized.

The movable conductive plate is disposed on the winding wheel 430, and one end of the USB wire is welded to the movable conductive plate. When the winding wheel 430 rotates, the movable conductive plate can be driven to rotate. The lower winding shell 411 has an outlet, and the other end of the USB cable 180 is electrically connected to the charging head 132 through the outlet and the charging head slot 131. The fixed conductive plate 441 is disposed on the movable conductive plate and electrically connected to the movable conductive plate. In one embodiment, the fixed conductive plate 441 and the movable conductive plate may be electrically connected through a Pogo Pin 442. The fixing conductive plate 441 is fixedly disposed on the winding upper case 410, and the winding upper case 410 is fastened to the winding lower case 411. The wire winding upper case 410 has an outlet through which the fixed conductive plate 441 is electrically connected to the communication control board 161 through an external wire 470. The energy storage battery 150 supplies power to the USB cable 180 through the external connection wire 470, the fixed conductive plate 441, the Pogo Pin442, and the mobile conductive plate. When the USB cable 180 is stretched or retracted, the movable conductive plate is rotated, but the fixed conductive plate 441 does not rotate, so that the USB cable 180 can be prevented from being damaged due to tangling.

referring to fig. 24, in one embodiment, a side of the winding line lower shell 411 away from the winding wheel 430 is provided with a winding wheel 430, a winding wheel spring 450, a winding wheel lock 460 and a winding wheel lock rotating shaft 461. The reel spring 450 abuts against the reel lock 460, and can drive the reel lock 460 to rotate around the reel lock rotating shaft 461. When the user stretches the USB wire 180, the winding wheel 430 rotates to drive the winding wheel lock rotating shaft 461 and the winding wheel lock 460 to rotate clockwise, the winding wheel lock 460 is disengaged from the USB wire 180, and the winding wheel spring 450 is compressed to generate elastic potential energy. When the USB cable 180 is pulled to a proper position and the pulling is stopped, the elastic force of the reel spring 450 pushes the reel lock rotating shaft 461 to rotate counterclockwise to an initial position, so that the reel lock 460 locks the USB cable 180, the length of the USB cable 180 is not changed, and the USB cable 180 is prevented from being automatically retracted and causing inconvenience in use.

In one embodiment, the solar energy storage device 10 further comprises a line winding unlock button 190 and a line winding unlock spring 191. The winding unlocking button 190 is embedded in the energy storage shell 110, one end of the winding unlocking button 190, which is located inside the energy storage shell 110, is abutted to the winding wheel lock catch 460, and the other end of the winding unlocking button 190 is fixed to the energy storage shell 110 through the winding unlocking spring 191. When the user stretches the USB wire 180, the winding wheel 430 rotates to drive the winding wheel lock rotating shaft 461 and the winding wheel lock 460 to rotate clockwise, the winding wheel lock 460 is disengaged from the USB wire 180, and the winding wheel spring 450 is compressed to generate elastic potential energy. When the user presses the wire winding unlocking button 190 after using the USB wire 180, the wire winding unlocking spring 191 is compressed to drive the winding wheel lock catch 460 to rotate clockwise, and disengage from the USB wire 180, and the USB wire 180 can automatically retract under the action of the spiral spring 420. When the winding unlocking button is released at any position, the winding wheel lock catch 460 can clamp the USB cable 180 and stay at the current position. The winding unlocking button 190 and the winding unlocking spring 191 can realize that the USB cable 180 can be automatically retracted by one key, so that the USB cable winding device is convenient to use.
