[0043] Please see Figure 1 This application provides a solar energy storage device 10, including an energy storage housing 110, a charging plug-in device 130 (including a charging head slot 131 and a charging head 132), an energy storage battery 150, a heat dissipation component 300, a communication control component 160 (including a communication control board 161, a QR code 163 and an antenna 164), a detection component 170, a lifting mechanism 200 and a winding mechanism 400.

[0044] The energy storage battery 150 is disposed inside the energy storage housing 110. The energy storage battery 150 is used for electrical connection with the solar power generation device. The energy storage battery 150 can store the electrical energy generated by the solar power generation device and charge external devices according to user needs.

[0045] Please see Figure 2-5 The solar energy storage device 10 also includes a lifting mechanism 200. The lifting mechanism 200 is fixedly mounted on the energy storage housing 110 and is used to fix the energy storage housing 110 to the guide rod 256 and drive the energy storage housing 110 to move along the axis of the guide rod 256.

[0046] In one embodiment, the lifting mechanism 200 includes a lifting housing 210 and a retaining ring mechanism 230. The lifting housing 210 has an annular channel 255 extending through the housing. The annular channel 255 is used to pass through the guide rod 256. The retaining ring mechanism 230 is disposed within the lifting housing 210 and surrounds the annular channel 255, and is used to change the size of the annular channel 255.

[0047] In one embodiment, the lifting housing 210 includes a first sub-housing 211 and a second sub-housing 212. The first sub-housing 211 and the second sub-housing 212 are joined to form the annular channel 255. The ring-holding mechanism 230 is disposed on the first sub-housing 211.

[0048] In one embodiment, the ring-holding mechanism 230 includes a free end 222 and a fixed end 221. The fixed end 221 is fixedly disposed at the edge of the annular channel 255. The lifting mechanism 200 further includes an adjusting member 224, which is movably mounted on the lifting housing 210. The adjusting member 224 is used to change the size of the annular channel 255 by defining the position of the free end 222.

[0049] In one embodiment, the adjusting element 224 is selected from the adjusting screw.

[0050] In one embodiment, the lifting mechanism 200 includes an adjusting screw 224, and the circumferential mechanism 230 includes a fixed end 221 and a free end 222. The fixed end 221 is fixedly disposed on the first sub-housing 211, and the free end 222 has a screw hole 223. The second sub-housing 212 has a through hole 213. The adjusting screw 224 passes through the through hole 213 and the screw hole 223 to connect the second sub-housing 212 and the circumferential mechanism 230, and can adjust the diameter of the annular channel 255 by means of the adjusting screw 224.

[0051] In one embodiment, the lifting mechanism 200 further includes a fixing screw 215, and the first sub-housing 211 is provided with a fixing hole 214. The fixing end 221 is fixed to the first sub-housing 211 by the cooperation of the fixing screw 215 and the fixing hole 214.

[0052] In one embodiment, the second sub-housing 212 has a groove 219, and the through hole 213 is disposed at the bottom of the groove 219. The adjusting screw 224 can be embedded in the groove 214, so that the adjusting screw 224 can avoid being exposed on the surfaces of the first sub-housing 211 and the second sub-housing 212.

[0053] In one embodiment, the first sub-housing 211 and the second sub-housing 212 are each provided with a connecting threaded hole 218. The connecting threaded 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 the connecting screw 216.

[0054] In one embodiment, the lifting mechanism 200 further includes a cover 240. The cover 240 is fastened to the side of the lifting housing 210 near the free end 222.

[0055] In one embodiment, there may be two clamping mechanisms 230. The clamping mechanisms 230 are bent at the annular channel 255. The two clamping mechanisms 230 surround to form the annular channel 255.

[0056] In the above embodiment, during the process of screwing the adjusting screw 224 into the screw hole 223, the adjusting screw can apply pressure to the clamping ring mechanism 230, causing the clamping ring mechanism 230 to clamp the guide rod 256. The pressure applied to the clamping ring mechanism 230 depends on the length of the adjusting screw 224 screwed into the screw hole 223. That is, the longer the adjusting screw 224 is screwed into the screw hole 223, the greater the pressure applied by the adjusting screw 224 to the clamping ring mechanism 230, and the tighter the clamping ring mechanism 230 clamps the guide rod 256. When the adjusting screw 224 is screwed out of the screw hole 223, the pressure applied to the clamping ring mechanism 230 decreases or even disappears, and the pressure between the clamping ring mechanism 230 and the guide rod 256 decreases or even disappears. The clamping ring mechanism 230 separates from the guide rod 256. After the clamping ring mechanism 230 separates from the guide rod 256, the lifting mechanism 200 can move up and down along the guide rod 256 or rotate around the guide rod 256. The height of the solar energy storage device 10 can be adjusted by adjusting the adjusting screw, making it easy to operate and convenient to use.

[0057] Please see Figure 6-8 In one embodiment, the ring-holding mechanism 230 includes a free end 222 and a fixed end 221. The lifting mechanism 200 includes a ring-holding shaft 251, a torsion spring 252, and an unlocking button 254. The ring-holding shaft 251 is disposed on the first sub-housing 211. The fixed end 221 is sleeved on the ring-holding shaft 251. The torsion spring 252 is sleeved on the ring-holding shaft 251. The two engaging ends of the torsion spring 252 abut against the ring-holding mechanism 230 and the first sub-housing 211, respectively. The unlocking button 254 abuts against the free end 222. The unlocking button 254 can change the size of the annular channel 255 by squeezing the free end 222.

[0058] In one embodiment, the free end 222 is provided with an abutting inclined surface 225. When the unlock button 254 pushes the retaining ring mechanism 230 along the abutting inclined surface 225, the retaining ring mechanism 230 overcomes the elastic force of the torsion spring 252 and expands the diameter of the annular channel 255.

[0059] In one embodiment, the first sub-housing 211 has a receiving groove 217. The unlocking button 254 passes through the receiving groove 217 and abuts against the abutting inclined surface 225.

[0060] 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 receiving groove 217, and the other end abuts against the unlocking button 254.

[0061] In one embodiment, the lifting mechanism 200 is connected to the energy storage housing 110. The lifting mechanism 200 is used to fix the solar energy storage device 10 to the guide rod 256. The lifting mechanism 200 may include a lifting housing 210. The lifting housing 210 has a main rod hole in the middle that matches the shape of the guide rod 256. The main rod hole may be the annular channel 255, so as to install the solar energy storage device 10 on the guide rod 256.

[0062] In one embodiment, the retaining ring shaft 251 is disposed on the first sub-housing 211. The fixed end 221 is sleeved on the retaining ring shaft 251. The torsion spring 252 is sleeved on the retaining ring shaft 251, and the two engaging ends of the torsion spring 252 abut against the retaining ring mechanism 230 and the first sub-housing 211, respectively.

[0063] The unlock button 254 abuts against the free end 222. The unlock button 254 is used to change the size of the annular channel 255 by squeezing the free end 222.

[0064] In this embodiment, the two engaging ends of the torsion spring 252 abut against the retaining ring mechanism 230 and the first sub-housing 211, respectively, causing the retaining ring mechanism 230 to tend to bend towards the annular channel 255, thereby gripping the guide rod 256. When the unlocking button 254 abuts against the free end 222, it causes the retaining ring mechanism 230 to move away from the annular channel 255, thereby releasing the guide rod 256.

[0065] In one embodiment, a gap may be provided between the retaining ring mechanism 230 and the inner wall of the first sub-housing 212 to facilitate the separation of the retaining ring mechanism 230 from the guide rod 256. The bend in the retaining ring mechanism 230 may form one inner wall of the annular channel 255. The second sub-housing 212 may form the other inner wall. The bend in the retaining ring mechanism 230 and the bend in the inner wall of the second sub-housing 212 together form the annular channel 255, facilitating the mounting of the energy storage housing 110 to the guide rod 256.

[0066] In the above embodiment, the second sub-shell 212 and the first sub-shell 211 can be fixed to the energy storage shell 110 by connecting screws. The second sub-shell 212 can be fixedly attached to the first sub-shell 211 by fixing screws, such that the bend of the ring-holding mechanism 230 and the bend of the inner wall of the second sub-shell 212 surround and form the annular channel 255, and the second sub-shell 212 and the first sub-shell 211 fit together to form a complete connecting body.

[0067] In one embodiment, the free end 222 is provided with an abutting inclined surface 225. When the unlock button 254 pushes the retaining ring mechanism 230 along the abutting inclined surface 225, the retaining ring mechanism 230 overcomes the elastic force of the torsion spring 252 and expands the diameter of the annular channel 255. It can be understood that the abutting inclined surface 225 is inclined in a direction away from the annular channel 255; therefore, when the unlock button 254 moves vertically towards the abutting inclined surface 225, the retaining ring mechanism 230 will move in a direction away from the annular channel 255, thereby expanding the diameter of the annular channel 255.

[0068] In one embodiment, the first sub-shell 211 has a receiving groove 217, through which the unlock button 254 passes and abuts against the abutting inclined surface 225. The receiving groove 217 has a certain depth, thus preventing the unlock button 254 from being directly exposed to the surface of the first sub-shell 211 and protecting the unlock button 254 from damage.

[0069] 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 receiving groove 217, and the other end abuts against the unlocking button 254. When the unlocking button 254 is pressed, the unlocking spring 253 is compressed, the diameter of the annular channel 255 increases, and the friction between the lifting mechanism 200 and the guide rod 256 decreases, allowing the lifting mechanism 200 to move.

[0070] In one embodiment, the bottom of the receiving groove 217 has a hole that matches the size of the unlock button 254. An annular protrusion surrounds the hole, and the unlock spring 253 is disposed outside the annular protrusion. One end of the unlock button 254 can be fixed to the unlock spring 253.

[0071] In the above embodiment, when the unlock button is pressed, the retaining ring mechanism 230 is squeezed and deformed, compressing the unlocking spring 253 and causing the retaining ring mechanism 230 to separate from the guide rod 256. After the retaining ring mechanism 230 separates from the guide rod 256, the lifting mechanism 200 can move up and down along the guide rod 256 or rotate around the guide rod 256. When the unlock button 254 is released, the elastic force of the unlock button 254 spring pushes the unlock button 254 back to its original position. At the same time, the retaining ring mechanism 230 recovers its shape under the action of the unlocking spring 253 and re-fits the guide rod 256, thus fixing the lifting mechanism 200 to the guide rod 256. By pressing the unlocking spring 254, the height of the lifting mechanism 200 can be adjusted, that is, the height of the solar energy storage device 10 can be adjusted for convenient use.

[0072] In one embodiment, the fixed end 221 is rotatably disposed on the torsion spring 252. When the unlock button 254 presses the retaining ring mechanism 230 and deforms it, the retaining ring mechanism 230 separates from the guide rod 256. When the unlock button 254 is released, the elastic force of the torsion spring 252 pushes the retaining ring mechanism 230 to rotate around the torsion spring 252 and engage with the guide rod 256, thereby fixing the lifting mechanism 200 to the guide rod 256. By pressing the unlock button 254, the torsion spring 252 can be adjusted through the retaining ring mechanism 230, thereby changing the size of the annular channel 255 and adjusting the height of the lifting mechanism 200 for user convenience.

[0073] In one embodiment, the lifting mechanism 200 further includes a rubber friction strip 260. The rubber friction strip 260 can be attached to the curved portion of the retaining ring mechanism 230 and the curved 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 friction strip 260 directly contacts the guide rod 256, increasing the friction between the annular channel 255 and the guide rod 256. This makes the lifting mechanism 200 more securely fixed to the guide rod 256, preventing slippage.

[0074] Please see Figure 9 , Figure 10 and Figure 11In one embodiment, the solar energy storage device 10 includes a drive device 120 and at least one charging plug-in device 130, the charging plug-in device 130 being disposed on the energy storage housing 110. Each charging plug-in device 130 further includes a drive assembly 121, a transmission member 133, and an elastic member 134. The drive assembly 121 is driveably connected to the drive device 120. The transmission member 133 is disposed on the energy storage housing 110. One end of the transmission member 133 is used to cooperate with the drive assembly 121, and the other end contacts the charging head 132, thereby confining the charging head 132 within 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.

[0075] One end of the elastic element 134 abuts against the energy storage housing 110. The other end of the elastic element 134 abuts against the transmission element 133. When the driving device 120 drives the transmission element 133 through the driving assembly 121, the transmission element 133 can compress the elastic element 134 and release the charging head 132.

[0076] In one embodiment, the charging connector 130 further includes a cam 122. The cam 122 is fixedly mounted on the drive assembly 121. One end of the transmission member 133 engages with the cam working surface 123 of the cam 122, and the other end contacts the charging head 132, thereby confining the charging head 132 within 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 via the cam working surface 123, the cam 122 compresses the elastic member 134, and the elastic member 134 releases the charging head 132.

[0077] In one embodiment, the driving device 120 is a drive motor. The driving assembly 121 is a drive shaft.

[0078] The drive assembly 121 is a drive shaft. The charging plug-in device 130 also includes a cam 122. The cam 122 is fixedly mounted on the drive shaft. The drive shaft drives the transmission component 133 to move via the cam 122.

[0079] In one embodiment, the driving device 120 can be a stepper motor. The stepper motor, also known as a pulse motor, is a freely rotating electromagnet based on the principle of electromagnetism. The stepper motor generates electromagnetic torque by changing the air gap magnetic permeability, converting electrical pulse signals into angular displacement of the drive shaft, thus driving the drive shaft to rotate. The energy storage battery 150 can power the stepper motor. The cam 122 is fixedly mounted on the drive shaft. The stepper motor can control the rotation of the cam 122 via the drive shaft. The cam working surface 123 of the cam 122 can abut against one end of the transmission member 133. The charging head 132 can be plugged into and unplugged into the charging head slot 131.

[0080] In the above embodiment, after the charging head 132 is inserted into the charging head slot 131, one end of the elastic member 134 can squeeze the transmission member 133. The transmission member 133 moves towards the opening of the charging head slot 131. The end of the transmission member 133 away from the elastic member 134 can lock the end of the charging head 132 away from the bottom of the charging head slot 131, thus preventing the charging head 132 from leaving the charging head slot 131. When the cam 122 rotates, causing the cam working surface 123 to contact and abut against one end of the transmission member 133, the transmission member 133 can compress the elastic member 134. At this time, the transmission member 133 releases the charging head 132. The charging head 132 can then leave the charging head slot 131.

[0081] Please see Figure 12 and Figure 13 In one embodiment, the driving device 120 includes an electromagnet 140. The electromagnet 140 has a movable shaft 142. When the electromagnet 140 is energized, it can drive the movable shaft 142 to move axially, and the electromagnet 140 drives the transmission element 133 to move through the movable shaft 142. One end of the transmission element 133 abuts against one end of the movable shaft 142, and the other end abuts against the charging head 132.

[0082] When the electromagnet 140 is de-energized, the elastic element 134 pushes the transmission element 133 and the movable shaft 142, and the transmission element 133 limits the charging head 132 to the charging head slot 131. When the electromagnet 140 is energized, the movable shaft 142 pushes the transmission element 133, causing the transmission element 133 to compress the elastic element 134, while the transmission element 133 releases the charging head 132.

[0083] In one embodiment, the electromagnet 140 has a through slot 141. The movable shaft 142 passes through the through slot 141. When the electromagnet 140 is energized, it drives the movable shaft 142 to extend and retract axially in the through slot 141, and the electromagnet 140 drives the transmission member 133 to move through the movable shaft 142.

[0084] In one embodiment, the electromagnet 140 has a hollow structure, which can form the through slot 141. The movable shaft 142 can be disposed within the hollow structure. The electromagnet 140 can control the reciprocating linear motion of the movable shaft 142, thereby controlling the transmission member 133 to compress or release the elastic member 134. In one embodiment, the electromagnet 140 can be a hollow cuboid, and the movable shaft 142 can be a slender cylinder disposed within the hollow structure of the electromagnet 140. In one embodiment, one end of the elastic member 134 abuts against the transmission member 133, and the other end is disposed on the inner wall of the energy storage housing. When the charging head 132 is removed and the spring is in a balanced position without force, the transmission member 133 is in the charging head slot 131.

[0085] In one embodiment, after the charging head 132 is inserted into the charging head slot 131, the charging head 132 is confined within the charging head slot 131, causing the elastic element 134 to be in a compressed state. When the user scans the QR code 163, the antenna can control the communication control component 160 to transmit a pulse signal to the electromagnet 140. The electromagnet 140 is energized, generating an internal magnetic field, thereby pushing the movable shaft 142 downward from its initial position. The contact portion between the movable shaft 142 and the transmission component 133 is squeezed, causing the transmission component 133 to move away from the charging head slot 131, further compressing the elastic element 134. At this time, the transmission component 133 separates from the charging head 132. When the charging head 132 is fitted into the charging head slot 131, the male end of the connector (Pogo Pin) 172 contacts and squeezes the female end, compressing the elastic body of the female end of the connector 172 and generating elastic potential energy. Therefore, when the transmission component 133 separates from the charging head 132, the elastic body at the female end of the connector 172 tends to return to its original state and generates elastic force. This elastic force acts on the male end of the connector 172, causing the female end of the connector 172 to pop out. Thus, the user can unlock the charging head 132 by scanning the QR code 163, allowing the charging head 132 to pop out of the charging slot 131, which is convenient, quick, and easy to use.

[0086] After the pulse signal passes, the electromagnet 140 is de-energized, and its internal magnetic field disappears. The movable shaft 142 moves upward back to its initial position. The movable shaft 142 no longer presses against the transmission member 133, causing the transmission member 133 to release the elastic member 134, which then pushes the transmission member 133 back. Under the thrust of the elastic member 134, the transmission member 133 moves towards the charging head slot 131. When the elastic member 134 returns to its equilibrium position, the transmission member 133 secures the charging head 132 within the charging head slot 131.

[0087] When the charging head 132 is inserted into the charging head slot 131, the contact portion of the charging head 132 and the transmission member 132 is squeezed, pushing the transmission member 133 to compress the elastic member 134. The contact portions of the charging head 132 and the transmission member 133 are engaged together, thereby securing the charging head 132 within the charging head slot 131. Simultaneously, the male end of the connector 172 contacts and compresses the female end of the connector 172 again. At the same time, the Hall element 173 of the detection board 171 detects the magnetic field of the detection magnet 174. The detection board 171 sends a feedback signal to the communication control board 161, indicating that the charging head 132 has been returned. The communication control board (161) receives the feedback signal and then reports it to the cloud server 165 via the antenna (164). The cloud server 165 can further deduct fees based on the charging duration through the user terminal APP 167.

[0088] In the above embodiments, the charging plug-in device may further include a support rail 135, the transmission member 135 includes a sliding part 136, one end of the sliding part 136 is provided with a blocking surface 137, and the charging head 132 is provided with a locking surface 1371. The support rail and the transmission member 133 surround and form an elastic element receiving cavity 144 and other structures. The specific structural form may be the same as or similar to the aforementioned embodiments, and will not be described in detail here.

[0089] In one 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. The three charging head slots 131 are arranged side by side in the energy storage housing 110. The electromagnet 140 and the movable shaft 142 may also be three sets, housed within a receiving housing 143. The three charging heads 132 and the three charging head slots 131 can be used independently.

[0090] In one embodiment, the solar energy storage device 10 further includes 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 component 160 includes a communication control board 161.

[0091] Please see Figure 14 The communication control board 161 is disposed on the surface of the liquid-cooled radiator 310 away from the energy storage battery 150.

[0092] In one embodiment, the communication control assembly 160 further includes a control board bracket 162. The control board bracket 162 is disposed between the liquid-cooled radiator 310 and the energy storage battery 150, and is used to support the communication control board 161. The control board bracket 162 can surround the liquid-cooled radiator 310 and the energy storage battery 150, and is fixed to the inner wall of the energy storage housing 110 by screws.

[0093] Please see Figure 15 and Figure 16 In one embodiment, the solar energy storage device 10 further includes a charging connector 130. The charging connector 130 includes a charging head 132 and a charging head slot 131. The charging head 132 is electrically connected to the energy storage battery 150 via a USB cable 180 and the communication control component 160. The charging head slot 131 is disposed in the housing. The shape of the charging head slot 131 matches the charging head 132, allowing the charging head 132 to fit into the charging head slot 131.

[0094] In one embodiment, the communication control board 161 is electrically connected to the energy storage battery 150. The communication control board 161 is connected to the charging head 132 via the USB cable 180. The energy storage battery 150 can supply power to the charging head 132 through the communication control board 161.

[0095] Please see Figure 17-18 In one embodiment, the solar energy storage device 10 further includes a detection component 170. The detection component 170 is electrically connected to the charging head 132 and is used to detect the operating status of the charging head 132. The energy storage battery 150 transmits pulse signals to the charging head 132 via the communication control component 160. The detection component 170 determines the operating status of the charging head 132 based on the pulse signals. The detection component 170 is electrically connected between the communication control board 161 and the charging head 132. The detection component 170 is used to detect whether the USB cable 180 is intact and transmits the detection result to the communication control board 161.

[0096] In one embodiment, the detection component 170 includes a detection plate 171 and a connector (Pogo Pin) 172. The detection plate 171 is disposed in the charging head slot 131 and is used to detect the operating status of the charging head 132. The male end of the connector 172 is disposed in the detection plate 171, and the female end of the connector 172 is disposed in the charging head 132. The male end and the female end of the connector 172 are in electrical contact. When the elastic member 134 releases the charging head 132, the female end of the connector 172 ejects the charging head 132 from the charging head slot 131 through the male end of the connector 172.

[0097] In one embodiment, the communication control board 161 is electrically connected to both the charging head 132 and the detection board 171, and is used to send a detection signal to the charging head 132. In one embodiment, the detection signal is a pulse signal.

[0098] The detection plate 171 is fitted to the inner wall of the bottom surface of the charging head slot 131. A through hole is formed on the bottom surface of the charging head slot 131. The male end of the connector 172 can be disposed on the detection plate 171 and electrically connected to it, extending into the groove through the through hole. The female end of the connector 172 can be disposed on the charging head 132. When the charging head 132 is inserted into the charging head slot 131, one end of the detection plate 171 is electrically connected to the charging head 132 through the male and female ends of the connector 172. The charging head 132 is also 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 plate 171 is electrically connected to the communication control board 161. Therefore, the communication control component 160, the USB cable 180, the charging head 132, the male and female ends of the connector 172, and the detection plate 171 constitute a closed loop. The energy storage battery 150 can be controlled by the communication control component 160 to emit a pulse signal. The pulse signal travels through the USB cable 180 and the charging head 132 to the detection board 171. The detection board 171 can 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 faulty and transmits the fault information to the communication control component 160. In one embodiment, the communication control board 161 can also upload the information regarding the integrity of the USB cable 180 to a cloud server 165. The cloud server 165 can transmit the information regarding the integrity of the USB cable 180 to a maintenance terminal 166. Maintenance personnel can use the maintenance terminal 166 to check the integrity of the USB cable 180 and further determine the location of the failure.

[0099] In the above embodiments, the detection plate 171 can be fixed to the inner wall of the bottom surface of the charging head slot 131 by screws or adhesive.

[0100] In one embodiment, the connector 172 may include four terminals, namely two positive and two negative terminals, to increase the overcurrent capacity. The four terminals form two closed loops. In either closed loop, the energy storage battery 150 can transmit a pulse signal via the communication control board 161. This pulse signal travels through the USB cable 180, the charging component, and a set of positive and negative terminals of the connector 172 to the detection PCB. The detection PCB can 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 PCB is incomplete, the detection PCB determines that the USB cable 180 is faulty and transmits the fault information to the communication control mechanism. The communication control board 161 can further upload the information regarding the integrity of the USB cable 180 to the cloud server 165. The cloud server 165 can transmit the information regarding the integrity of the USB cable 180 to the maintenance terminal 166. Maintenance personnel can use the maintenance terminal 166 to check the integrity of the USB cable 180 and further determine the location of the failure.

[0101] In one embodiment, the detection component 170 further includes a detection magnet 174 and a Hall element 173. The detection magnet 174 can be disposed on the charging head 132. The Hall element 173 can be disposed on the detection plate 171 for detecting the presence of the magnetic field generated by the detection magnet 174. When the charging head 132 is inserted into the charging head slot 131, the male and female ends of the connector 172 mate, and the Hall element 173 can detect the magnetic field of the detection magnet 174. The Hall element 173 sends a feedback signal to the communication control system. The communication control system receives the feedback signal, thereby determining that the USB charging head 132 has been successfully returned. The communication control system further uploads the determination information to the cloud server 165 for relevant billing and settlement.

[0102] In one embodiment, the communication control unit assembly further includes a QR code 163 and an antenna 164. The QR code 163 can be disposed on the outer surface of the energy storage housing 110. The outer surface of the energy storage housing 110 may have a groove, into which the QR code 163 is fitted and encapsulated with transparent plastic. In one embodiment, the QR code 163 can be disposed above the charging head slot 131 in the first energy storage sub-housing 111 for convenient user scanning. The communication control board 161 can be disposed inside the energy storage housing 110, conforming to the surface of the energy storage battery 150 away from the inner wall of the energy storage housing 110. The communication control unit assembly may further include a control board bracket 162 for fixing the communication control board 161 to the energy storage battery 150. The control board bracket 162 can surround the energy storage battery 150 and be fixed to the inner wall of the energy storage housing 110 by screws. The communication control board 161 and the energy storage battery 150 are connected via a cable. The antenna 164 can be disposed on the side surface of the energy storage battery 150 and electrically connected to the communication control board 161. The antenna 164 can be used for communication with other device terminals. In one embodiment, the antenna 164 may include a GPS antenna and a GSM antenna (2G / 3G / 4G signal antenna). The GPS antenna can be fixed to one side of the inner wall of the energy storage housing 110 by a snap-fit ​​method. The GSM antenna can be attached to the other side of the inner wall of the energy storage housing 110 by double-sided adhesive. The GPS antenna and the GSM antenna can be disposed on both sides of the energy storage battery 150 to prevent mutual interference.

[0103] In one embodiment, since the communication control board 161 is electrically connected to the energy storage battery 150, the energy storage battery 150 can power other components through the communication control board 161. The energy storage battery 150 can emit a pulse signal through the communication control board 161 to control the locking / unlocking of the charging head 132. The communication control board 161 is electrically connected to the charging head 132 via the USB cable 180. The charging head 132 has a detection magnet 174. The charging head 132 is then electrically connected to the detection board 171 via the male and female terminals of the connector 172. The detection component 170 has a Hall element 173 that can detect the magnetic field of the detection magnet 174. The detection board 171 can detect the integrity of the USB cable 180 and whether the charging head 132 has been returned, and report the detection information to the communication control board 161. The communication control board 161 is also electrically connected to the antenna 164. The antenna 164 is communicatively connected to the cloud server 165. The antenna 164 can transmit information received from the communication control board 161 to the cloud. The cloud server 165 can transmit information about the integrity of the USB cable 180 to the maintenance terminal 166. Maintenance personnel can use the maintenance terminal 166 to check the integrity of the USB cable 180 and further determine the location of the failure.

[0104] The cloud server 165 can also send information about whether the charging head 132 has been returned to the user terminal 168 or the user-end APP 167. The user can use the user-end APP 167 to scan the QR code 163, thereby controlling the communication control board 161 to emit a pulse signal via the antenna 164. The pulse signal can unlock the charging head 132, causing it to pop out of the charging head slot 131, allowing the user to charge the device. When 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 communication control board 161 then reports the information to the cloud server 165 via the antenna 164. The cloud server 165 can further deduct fees based on the charging duration through the user-end APP 167.

[0105] In one embodiment, the energy storage battery 150 can transmit a pulse signal to the drive device 120 via the communication control component 160. Upon receiving the pulse signal, the drive device 120 drives the drive shaft to rotate clockwise. The rotational speed and angle of the drive shaft depend on the frequency and number of pulses of the pulse signal. The drive shaft can drive the cam 122 to rotate clockwise. The cam 122 presses against one end of the transmission member 133, causing the transmission member 133 to move closer to the inner wall 110 of the energy storage housing, further compressing the elastic member 134. The other end of the transmission member 133 separates from the charging head 132, allowing the charging head 132 to be removed. This achieves the unlocking action of the charging head 132. After the pulse signal passes, the drive device 120 loses power, driving the drive shaft to rotate counterclockwise back to its initial position. The drive shaft no longer presses against the first end, causing the transmission member 133 to release the elastic member 134, and the elastic member 134 returns to push the transmission member 133.

[0106] The transmission member 133 moves toward the opening of the charging head slot 131 under the thrust of the elastic member 134. When the elastic member 134 returns to its equilibrium position, one end of the transmission member 133 is in the charging head slot 131. When the charging head 132 is inserted into the charging head slot 131, the end of the charging head 132 and the transmission member 133 are pressed together, thereby securing the charging head 132 within the charging head slot 131.

[0107] In one embodiment, a slot is formed in the center of the cam 122. The slot matches the drive shaft. The drive shaft can be fitted into the slot, thereby fixing the cam 122 to the drive shaft.

[0108] In one embodiment, the cam 122 may include a protrusion. The transmission member 133 may include a first end and a second end. The protrusion abuts against the first end of the transmission member 133. When the stepper motor is energized, driving the drive shaft and the cam 122 to rotate clockwise, the protrusion can press against the first end. This causes the transmission member 133 to move towards the inner wall of the energy storage housing 110, separating the transmission member 133 from the charging head 132. In the above embodiment, the first end may include a slope that mates with the protrusion. The protrusion is disposed on the slope, further facilitating the protrusion to press against the first end.

[0109] In one embodiment, the contact portion between the second end and the charging head 132 can be a mating male and female buckle. The female buckle can be disposed at the end of the charging head 132, and the male buckle can be disposed at the second end. The contact surfaces of the male and female buckles can be parallel to each other and cooperate 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 and engages with the male buckle, so that the charging head 132 is inserted into and locked in the charging head slot 131.

[0110] In one embodiment, the support rail 135 and the transmission member 133 surround and form an elastic element receiving cavity 144. The elastic element 134 is disposed within the elastic element receiving cavity 144. The position of the elastic element 134 can be defined by the elastic element receiving cavity 144.

[0111] In one embodiment, the cross-section of the transmission member 133 can be E-shaped. The upper part of the E-shaped transmission member 133 can be the first end. The middle part of the E-shaped transmission member 133 serves as a guide post for the elastic member 134, used to fix the elastic member 134. The lower end of the E-shaped transmission member 133 near the charging head slot 131 can be the second end, i.e., the male buckle.

[0112] In one embodiment, the charging connector 130 further includes a support rail 135. The support rail 135 is disposed on the 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 support rail 135 to change the size of the outlet of the charging head slot 131.

[0113] The locking device further includes a support rail 135. The support rail 135 is fixedly attached to the inner wall of the energy storage housing 110. The side of the elastic member 134 away from the E-shaped transmission member 133 can be fixed to the support rail 135. The support rail 135 may include upper and lower rails, and the E-shaped transmission member 133 is fitted between the two rails. The upper and lower parts of the E-shaped transmission member 133 are in parallel contact with the two rails respectively. The rails can restrict the transmission member 133 to move left and right only in the horizontal direction, which facilitates the hooking of the male and female buckles. The sliding part 136 can be provided at the lower part of the E-shaped transmission member 133. The sliding part 136 can slide on the surface of the support rail 135.

[0114] In one embodiment, one end of the sliding portion 136 is provided with a blocking surface 137. The charging head is provided with a engaging surface 138, and the blocking surface 137 defines the charging head 132 within the charging head slot 131 via 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, thereby confining the charging head 132 within the charging head slot 131.

[0115] In one embodiment, when the charging head 132 is fitted into the charging head slot 131, the male end of the connector (PogoPin) 172 is located in the groove and contacts the female end of the connector 172 located on the charging head 132, generating compression. The elastomer of the female end of the connector 172 is compressed and generates elastic potential energy.

[0116] When a user uses the charging head 131, the user can scan a QR code (163) using the user terminal APP 167, causing the antenna 164 to control the communication control board (161) to emit 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, causing the transmission member 133 to move closer to the inner wall 110 of the energy storage housing, further compressing the elastic member 134. The other end of the transmission member 133 separates from the charging head 132. When the other end of the transmission member 133 separates from the charging head 132, the elastic body of the female end of the connector 172 tends to return to its original state and generate elastic force. The elastic force acts on the male end of the connector 172, causing the female end of the connector 172 to be ejected. That is, the charging head 132 is ejected under the interaction of the male and female ends of the connector 172, making it easy to remove and use the charging head 132. Therefore, users can unlock the charging head 132 by scanning the QR code 163, causing the charging head 132 to pop out of the charging slot 131, which is convenient, quick and easy to use.

[0117] When the charging head 132 is returned and reinserted into the charging head slot 131, the male end of the connector 172 and the female end of the connector 172 re-enter into contact and compress. Simultaneously, the Hall element 173 of the detection board 171 detects the magnetic field of the detection magnet 174. The detection board 171 sends a feedback signal to the communication control board 161, indicating that the charging head 132 has been returned. The communication control board 161 receives the feedback signal and then reports it to the cloud server 165 via the antenna 164. The cloud server 165 can further deduct fees based on charging duration through the user-end APP 167.

[0118] In one 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. The three charging head slots 131 are arranged side-by-side in the energy storage housing 110. The drive shaft 121 passes through the three charging head slots 131. Each charging head slot 131 includes a combination of a cam, a transmission element 133, an elastic element 134, and a support rail 135. The protrusions of the three cams 122 are arranged at 120 degrees to each other on the drive shaft 121. The three cams 122 can respectively unlock the three charging heads 132. The three cams 122, according to the angle of their protrusions from the slope surface (i.e., the angle at which they first and last contact the inclined surface of the first end during rotation), are designated as cam A, cam B, and cam C. Their corresponding other components are also labeled A, B, and C. Specifically, when the drive device 120 receives a rotation signal, the drive shaft 121 drives cams A, B, and C to rotate. The protrusion of cam A first contacts the inclined surface A it engages with, pressing the inclined surface A and causing the locking bracket A to move to the right, thereby unlocking the charging head A and causing it to pop out of the charging head slot A. Since the length of the inclined surface A is limited, cam A continues to rotate and disengages from the inclined surface A. At this point, the inclined surface A is no longer compressed, and the transmission component A returns to its original position. Because the rotation angle of the drive shaft 121 is less than 120 degrees at this time, cams B and C are not triggered, meaning that the charging head B and charging head C remain locked. When the drive shaft 121 rotates more than 120 degrees, the protrusion of cam B will contact the inclined surface, thereby unlocking the charging head B. Similarly, when the drive shaft 121 continues to rotate more than 240 degrees, cam C will be triggered to unlock the charging head C. Therefore, when the stepper motor receives a rotation signal, the cams A, B, and C can be triggered sequentially, thereby unlocking the three charging heads 132 in sequence.

[0119] In one embodiment, the locking device further includes a top cover 139. The top cover 139 is used to encapsulate the cam A, the cam B, and the cam C within the energy storage housing 110. The top cover 139 is provided with a slot that matches the top end of the transmission member 133.

[0120] Please see Figure 19In one embodiment, the heat dissipation assembly 300 includes a liquid-cooled radiator 310, which is attached to the energy storage battery 150. The liquid-cooled radiator 310 contains a cooling circulating fluid. The cooling circulating fluid can be water or ethylene glycol. The cooling fluid in the liquid-cooled radiator 310 circulates, thereby carrying away the heat generated by the energy storage battery 150 and protecting the energy storage battery 150. The energy storage housing 110 may be provided with orifices to allow the liquid-cooled radiator 310 to communicate with external circulation pumps, water tanks, and heat exchangers. The cooling circulating fluid can thus circulate between the inside and outside of the solar energy storage device 10. Specifically, the cooling circulating fluid carries away the heat generated inside the solar energy storage device 10 and dissipates it into the external environment; the cooler cooling circulating fluid is then pumped back into the solar energy storage device 10.

[0121] In one embodiment, the liquid-cooled radiator 310 is arranged around the energy storage battery 150. By arranging the liquid-cooled radiator 310 in a surrounding manner, the contact area between the liquid-cooled radiator 310 and the energy storage battery 150 can be increased, thereby improving heat dissipation efficiency.

[0122] In one embodiment, the liquid-cooled radiator 310 is a serpentine tube radiator. The serpentine tube is coiled and bent around the surface of the energy storage battery 150. The cooling circulating fluid flows within the serpentine tube. The energy storage housing 110 may be provided with an aperture that matches the size of the serpentine tube. The serpentine tube radiator can be connected to external circulation pumps, water tanks, and heat exchangers through the aperture. The cooling circulating fluid can circulate between the inside and outside of the energy storage device through the serpentine tube. Specifically, the cooling circulating fluid carries away heat from inside the energy storage device, enters the external water tank and heat exchanger through the serpentine tube, and dissipates it into the external environment. The cooled circulating fluid at a lower temperature is then pumped back into the solar energy storage device 10, and the above process is repeated. Thus, the heat generated inside the solar energy storage device 10 can be continuously dissipated into the external environment, thereby cooling the solar energy storage device 10.

[0123] In one embodiment, the heat dissipation assembly 300 includes a plate heat sink 320, the energy storage battery 150 includes a first surface and a second surface disposed opposite to each other, the liquid-cooled heat sink 310 is disposed on the first surface, and the plate heat sink 320 is disposed on the second surface.

[0124] In the above embodiment, the liquid-cooled heat sink 310 can be bent into a groove shape. The groove shape matches the shape of the energy storage battery 150 so as to be fastened to the first surface. This increases the heat dissipation area and improves heat dissipation efficiency.

[0125] In the above embodiments, the plate-type heat sink 320 utilizes the good thermal conductivity of aluminum and has multiple heat sinks, increasing the contact surface with air and thus effectively improving heat dissipation efficiency. The plate-type heat sink 320 not only has good heat dissipation but also features an attractive appearance, light weight, and good energy-saving performance. The heat generated by the energy storage battery 150 can be dissipated into the air through heat conduction via the plate-type heat sink 320, thereby protecting the energy storage battery 150 and extending its service life. The plate-type heat sink 320 can be fixed to the second surface by means of bonding, snap-fitting, screws, etc.

[0126] The liquid-cooled radiator 310 and the plate radiator 320 work together to greatly improve heat dissipation efficiency, promptly dissipating the heat generated by the energy storage battery 150 to the solar energy storage device 10. This solves the problem of heat accumulation in the solar energy storage device 10, which seriously affects charging efficiency, damages the solar energy storage device 10, shortens its service life, burns out charging equipment, and even causes fires.

[0127] Please see Figure 20 In one embodiment, the plate-type heat sink 320 surrounds a cavity, and the energy storage battery 150 is disposed in the cavity. In this embodiment, the plate-type heat sink 320 is designed as a cylindrical structure that matches the sidewall of the energy storage battery 150. The energy storage battery 150 is fitted into the cylindrical structure, which increases the contact area between the plate-type heat sink 320 and the energy storage battery 150, thereby further improving the efficiency of heat transfer and heat dissipation. This solves the problem of heat accumulation in the solar energy storage device 10, which seriously affects charging efficiency, damages the solar energy storage device 10, shortens its service life, burns out the charging equipment, and even causes a fire.

[0128] In one embodiment, the heat dissipation assembly 300 further includes a thermally conductive silicone pad 330 disposed between the plate heat sink 320 and the energy storage battery 150. The thermally conductive silicone pad 330 possesses good flexibility, insulation, compressibility, and surface adhesion. The thermally conductive silicone pad 330 allows the energy storage battery 150 and the plate heat sink 320 to fit tightly together, thereby improving heat transfer efficiency. It also serves as insulation and shock absorption, protecting the energy storage battery 150.

[0129] Please see Figure 21In one embodiment, the energy storage housing 110 includes: a first energy storage sub-housing 111, a second energy storage sub-housing 112, and a waterproof ring 113. The first energy storage sub-housing 111 and the second energy storage sub-housing 112 are fastened together, and the waterproof ring 113 is disposed between the first energy storage sub-housing 111 and the second energy storage sub-housing 112. The first energy storage sub-housing 111 is provided with a waterproof ring 113 mounting groove. The waterproof groove can be placed in the waterproof ring 113 mounting groove. The second energy storage sub-housing 112 is provided with a waterproof support. The waterproof support is pre-pressed against the waterproof ring 113 to fix the waterproof ring 113. The front shell and the rear shell are then fixedly connected by screws, clips, etc., which can achieve waterproofing of various components inside the housing.

[0130] Please see again Figure 1 In one embodiment, the solar energy storage device 10 further includes a winding mechanism 400. The winding mechanism 400 is disposed inside the energy storage housing 110 and is used to house the USB cable 180. Further, the winding mechanism 400 can be fitted inside the second energy storage sub-housing 112.

[0131] Please see Figure 22 The winding mechanism 400 includes an upper winding shell 410, a lower winding shell 411, a spring 420, a winding wheel 430, a rotating conductive plate 440, and a fixed conductive plate 441. The winding wheel 430 can be disposed on the lower winding shell 411. The lower winding shell 411 has a central shaft fixed thereon, and the winding wheel 430 is sleeved on the central shaft. The connection between the winding wheel 430 and the central shaft forms a groove for the spring 420. The spring 420 can be disposed in the groove, with one end engaged with the central shaft and the other end engaged with the winding wheel 430. The winding wheel 430 can drive the central shaft to rotate through the spring 420.

[0132] Please see Figure 23 The winding wheel 430 has parallel upper and lower sections on its edge, forming a winding groove. The USB cable 180 can be wound around the winding groove. When the winding wheel 430 rotates around its central axis, it causes the USB cable to extend or retract. Specifically, when the user uses the charging head 132 to stretch the USB cable 180, the winding wheel 430 rotates and compresses the spring 420, generating elastic force. When the user stops stretching, the external force disappears, the spring 420 tends to return to its original shape, thereby driving the winding wheel 430 to rotate, achieving automatic retraction of the USB cable 180.

[0133] The movable conductive plate is disposed on the reel 430, and one end of the USB cable is soldered to the movable conductive plate. When the reel 430 rotates, it can drive the movable conductive plate to rotate. The lower shell 411 of the reel has a cable outlet, and the other end of the USB cable 180 is electrically connected to the charging head 132 through the cable outlet and the charging head slot 131. The fixed conductive plate 441 is disposed on the movable conductive plate and is electrically connected to the movable conductive plate. In one embodiment, the fixed conductive plate 441 and the movable conductive plate can be electrically connected through a Pogo Pin 442. The fixed conductive plate 441 is fixedly disposed on the upper shell 410 of the reel, and the upper shell 410 is fastened to the lower shell 411 of the reel. The upper shell 410 of the reel has a cable outlet, and the fixed conductive plate 441 is electrically connected to the communication control board 161 through the cable outlet and the external wiring 470. The energy storage battery 150 supplies power to the USB cable 180 through the external wiring 470, fixed conductive plate 441, Pogo Pin 442, and movable conductive plate. When the USB cable 180 is stretched or retracted, it drives the movable conductive plate to rotate, but the fixed conductive plate 441 does not rotate, thus preventing the USB cable 180 from being tangled and damaged.

[0134] Please see Figure 24 In one embodiment, the outer casing 411 of the winding cable has a winding wheel 430, a winding wheel spring 450, a winding wheel latch 460, and a winding wheel latch shaft 461 on the side away from the winding wheel 430. The winding wheel spring 450 abuts against the winding wheel latch 460, which can drive the winding wheel latch 460 to rotate around the winding wheel latch shaft 461. When the user stretches the USB cable 180, the rotation of the winding wheel 430 causes the winding wheel latch shaft 461 and the winding wheel latch 460 to rotate clockwise, the winding wheel latch 460 disengages from the USB cable 180, and compresses the winding wheel spring 450 to generate elastic potential energy. When the USB cable 180 is stretched to a suitable position and the stretching stops, the elastic force of the reel spring 450 pushes the reel lock shaft 461 to rotate counterclockwise back to the initial position, so that the reel lock 460 locks the USB cable 180, and the length of the USB cable 180 no longer changes, preventing the USB cable 180 from automatically retracting and causing inconvenience in use.

[0135] In one embodiment, the solar energy storage device 10 further includes a cable unlocking button 190 and a cable unlocking spring 191. The cable unlocking button 190 is fitted into the energy storage housing 110. One end of the cable unlocking button 190 located inside the energy storage housing 110 abuts against the winding wheel lock 460, and the other end is fixed to the energy storage housing 110 by the cable unlocking spring 191. When the user stretches the USB cable 180, the winding wheel 430 rotates, causing the winding wheel lock shaft 461 and the winding wheel lock 460 to rotate clockwise. The winding wheel lock 460 disengages from the USB cable 180, compressing the winding wheel spring 450 to generate elastic potential energy. When the user finishes using the USB cable 180 and presses the cable unlocking button 190, the cable unlocking spring 191 is compressed, causing the winding wheel lock 460 to rotate clockwise and disengage from the USB cable 180. Under the action of the spring 420, the USB cable 180 can automatically retract. Releasing the cable unlock button at any position will cause the reel lock 460 to engage the USB cable 180, keeping it in its current position. The principle is the same as in the above embodiment and will not be repeated here. The cable unlock button 190 and the cable unlock spring 191 can automatically retract the USB cable 180 with a single click, making it convenient to use.
