[0066] Refer to the following Figures 1 to 28 A portable energy storage system according to some embodiments of the present application is described.

[0067] Embodiment 1

[0068] See also Figure 1 and Figure 2 As shown, an embodiment of the present application provides a portable energy storage system, comprising: a photovoltaic panel 1 and a bracket 2; wherein, the number of photovoltaic panels 1 is at least two, and any photovoltaic panel 1 is equipped with a bracket 2, and any bracket 2 includes a first bracket 21 and a second bracket 22, and the first bracket 21 is fixedly connected to the photovoltaic panel 1, and the second bracket 22 is rotatably connected to the first bracket 21; any two adjacent first brackets 21 and any two adjacent second brackets 22 are rotatably connected, and through the rotational connection between the adjacent two first brackets 21, the adjacent two second brackets 22 and the first bracket 21 and the second bracket 22, it is possible to realize that two adjacent photovoltaic panels 1 can be transformed between the unfolded or stored state.

[0069] Based on the structure described above, it can be known that when the portable energy storage system provided by the present application is in use, the two adjacent first brackets 21 and the two adjacent second brackets 22 can be first unfolded respectively, and then the second bracket 22 can be rotated and unfolded relative to the first bracket 21, thereby playing a role in supporting the photovoltaic panel 1 and the first bracket 21. When use is completed, the second bracket 22 can be rotated relative to the first bracket 21, and the second bracket 22 can be stored behind the photovoltaic panel 1, and then the two adjacent second brackets 22 and the two adjacent first brackets 21 can be rotated relative to each other, so as to fold the two adjacent photovoltaic panels 1.

[0070] It can be seen that the present application provides a personal photovoltaic energy storage system, which can be unfolded when in use and has a supporting structure. The overall structure is more solid and stable. It can be folded and stored after use. The overall structure is small and easy to carry and transport, which improves the convenience of use.

[0071] In this embodiment, preferably, Figure 2 As shown, any second bracket 22 includes a first support member 221 and a second support member 222; wherein, one side of the first support member 221 and one end of the second support member 222 are both rotatably connected to the first bracket 21, and the other side of the first support member 221 is rotatably connected to the other end of the second support member 222; the second support member 222 is a retractable structure.

[0072] According to the structure described above, the first support member 221 contacts the target ground such as the ground as a support base, and the second support member 222 is tilted relative to the vertical direction, that is, the photovoltaic panel 1 is tilted so that the photovoltaic panel 1 can be exposed to more sunlight.

[0073] Further, preferably, the first supporting member 221 is a U-shaped frame structure, and the openings of two adjacent first supporting members 221 are arranged opposite to each other. Of course, the present invention is not limited thereto.

[0074] In this embodiment, preferably, Figure 2 , Figures 7 to 12 , Fig.29 and Fig.30As shown, the second supporting member includes a mounting pipe 2221, a telescopic pipe 2222, a main pipe 2223, a traction member 2224, a positioning member 2225, a second wedge member 2226, a first wedge member 2227, a button 2228 and a stopper 2232; wherein the mounting pipe 2221 is rotatably connected to the first bracket 21; one end of the telescopic pipe 2222 is slidably connected to the mounting pipe 2221, and the other end of the telescopic pipe 2222 is fixedly connected to the positioning member 2225; one end of the main pipe 2223 is rotatably connected to the first supporting member 221, and the positioning member 2225 together with one end of the telescopic pipe 2222 are movably inserted into the other end of the main pipe 2223;

[0075] The limiting member 2232 is formed with an ultimate limiting protrusion 22321, and an ultimate limiting through hole 22222 is formed at one end of the main pipe member 2223 close to the telescopic pipe member 2222, and the ultimate limiting protrusion 22321 is inserted into the ultimate limiting through hole 22222, so that the limiting member 2232 is always located in the main pipe member 2223 and does not fall out;

[0076] The stopper 2232 is formed with a mounting cavity 22322 penetrating both sides thereof along the moving direction of the main pipe 2223, and the positioning member 2225 and one end of the telescopic pipe 2222 can move along the mounting cavity 22322; the side wall of the mounting cavity 22322 is formed with a sliding groove 22323 penetrating the side close to the main pipe 2223;

[0077] The positioning member 2225 forms a limiting protrusion 22251, which can slide along the slide groove 22323, and the side of the slide groove 22323 away from the main pipe 2223 plays the role of ultimately limiting the limiting protrusion 22251, so that the positioning member 2225 and the telescopic pipe 2222 will never be separated from the main pipe 2223; the limiting protrusion 22251 can pass through the slide groove and extend to the outer side of the limiting pipe 2232 away from the positioning member 2225; the main pipe 2223 is formed with a protrusion along its length The plurality of limiting through holes 22221 are sequentially arranged at intervals in the degree direction, and the limiting protrusion 22251 can be inserted into one of the limiting through holes 22221. It should be noted that: when the limiting protrusion 22251 moves into the slide groove 22323, the limiting protrusion 22251 can pass through the slide groove 22323 and be exposed to the outside, thereby not affecting the limiting protrusion 22251 being inserted into the 22221 described above; the first wedge member 2227 and the second wedge member 2226 are both arranged in the mounting pipe 2221;

[0078] The traction member 2224 is sequentially arranged in the mounting tube 2221 and the telescopic tube 2222, and one end of the traction member 2224 is connected to the second wedge member 2226, and the other end of the traction member 2224 is connected to the positioning member 2225; the button 2228 is movably mounted on the mounting tube 2221, and the mounting tube 2221 is formed with an opening, and at least part of the structure of the button 2228 can extend to the outside of the mounting tube 2221 through the opening; the first wedge member 2227 is connected to the button 2228; the first wedge member 2227 and the second wedge member 2226 are matched through the wedge surface; when the button 2228 is pressed down or released, the first wedge member 2227 drives the second wedge member 2226 to drive the traction member 2224 to move along the length direction of the telescopic tube 2222.

[0079] According to the structure described above, it can be known that by pressing the button 2228 downward, the first wedge-shaped member 2227 pushes the second wedge-shaped member 2226 to drive the traction member 2224 to move forward, thereby forcing the limiting protrusion 22251 on the positioning member 2225 at the front end of the traction member 2224 to be forced to disengage from the limiting through hole 22221 on the main pipe member 2223, thereby releasing the limiting of the main pipe member 2223, and then allowing the main pipe member 2223 to move toward or away from the telescopic pipe member 2222. This can also be achieved by pressing down or flipping up the photovoltaic panel 1, and when the main pipe member 2223 is moved toward or away from the telescopic pipe member 2222 to a suitable position, the limiting protrusion 22251 on the positioning member 2225 naturally falls into the limiting through hole 22221 on the main pipe member 2223, playing a limiting role, that is, keeping the state of the second supporting member 222 unchanged.

[0080] It can be seen that the above structure can be used to adjust the inclination angle of the photovoltaic panel 1 to meet different usage requirements. In particular, the angle of the photovoltaic panel 1 can be adjusted according to the position of the sun, so that the sunlight can be vertically irradiated on the photovoltaic panel 1 to improve the photovoltaic efficiency. In addition, the present application provides a new telescopic structure, which is more reliable, stable, and easier to operate, occupies less space, and has a higher degree of integration.

[0081] In this embodiment, preferably, Fig. 9 As shown, the portable energy storage system also includes an auxiliary limiting member 2229 and a return spring 2230; wherein the auxiliary limiting member 2229 is arranged inside the mounting tube 2221, and is located on the side of the second wedge-shaped member 2226 close to the positioning member 2225 and is arranged at intervals; the auxiliary limiting member 2229 is formed with a through hole, and the traction member 2224 is movably inserted into the through hole; the spring 45 is movably sleeved on the outside of the traction member 2224, and the spring 45 is arranged between the second wedge-shaped member 2226 and the auxiliary limiting member 2229.

[0082] According to the structure described above, the reset spring 2230 can reset the button 2228, thereby facilitating the next operation and making the process of pressing the button 2228 feel better.

[0083] It should be noted that the second support member 222 may also adopt other structures, that is, different telescopic rod structures in the prior art, which can be freely extended and retracted, and in particular, a telescopic rod with a locking function in the prior art can be selected to achieve locking. Of course, it is not limited to this.

[0084] In this embodiment, preferably, Fig. 9 As shown, the portable energy storage system further includes a position limiting member 2231 , and the position limiting member 2231 is disposed in the mounting pipe 2221 and is pressed onto the traction member 2224 .

[0085] According to the structure described above, it can be known that the limiting member 2231 serves to limit the traction member 2224, thereby preventing the traction member 2224 from deviating in a direction perpendicular to its moving direction.

[0086] In this embodiment, preferably, Figures 3 to 6 As shown, one of any two adjacent second brackets is formed with an auxiliary mounting groove 223, and the other one is formed with an auxiliary mounting protrusion 224, and the auxiliary mounting protrusion 224 is inserted into the auxiliary mounting groove 223 and rotatably connected; at least one side of the auxiliary mounting groove 223 close to the open end of the auxiliary mounting protrusion 224 is formed with a receiving groove 225 and a mounting hole 226 arranged in sequence; at least one side of the auxiliary mounting protrusion 224 is formed with a limiting hole 227 corresponding to the receiving groove 225;

[0087] The portable energy storage system also includes a spring 45, a limiting ball and a limiting cover plate, the spring 45 and the limiting ball are sequentially arranged in the mounting hole 226, and one end of the spring 45 abuts against the bottom wall of the auxiliary mounting groove 223, and the other end of the spring 45 abuts against the limiting ball; the limiting cover plate is arranged in the accommodating groove 225 and is used to limit the limiting ball; the limiting cover plate forms a limiting through hole, and when two adjacent brackets are unfolded, the spring 45 pushes the limiting ball to abut against the limiting cover plate, and makes the front structure of the limiting ball extend out of the limiting through hole, and is inserted into the limiting hole 227 to limit the two brackets so that the two adjacent second brackets remain in the unfolded state.

[0088] According to the structure described above, it can be known that when the two second brackets 22 are relatively unfolded, the limiting ball moves toward the limiting hole 227 of the other second bracket 22 under the action of the spring 45, and finally cooperates with the limiting hole 227 to play a limiting role, thereby ensuring that the two second brackets 22 remain in the unfolded state. When the two second brackets 22 are relatively rotated and folded, the other second bracket 22 will push the limiting ball to move toward the spring 45 side, and then disengage from the limiting hole 227, thereby contacting the limit, and then facilitating the two second brackets 22 to be folded relative to each other.
