[0062] To make the objectives, features, and advantages of this application more apparent and understandable, the technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0063] Existing solar energy storage devices are cumbersome and labor-intensive to operate in terms of unfolding and folding photovoltaic panels.

[0064] Therefore, this application provides a solar energy storage device.

[0065] Reference Figure 1 - Figure 6 In this application, the first direction X refers to the left-right direction of the solar energy storage device, the second direction Y refers to the front-back direction of the solar energy storage device, and the third direction Z refers to the up-down direction of the solar energy storage device.

[0066] The solar energy storage device of this application includes an energy storage body 100, on the top of which are multiple first mounting frames 200 connected in sequence. These first mounting frames 200 can be folded along a first direction X and placed on top of the energy storage body 100. A photovoltaic panel 300 is installed in each first mounting frame 200. Furthermore, the solar energy storage device of this application also includes a retractable assembly, and there are two sets of retractable assemblies. The two sets of retractable assemblies are located on both sides of the first mounting frame 200 along a second direction. The retractable assemblies are connected to the first mounting frame 200 to control the switching of the first mounting frame 200 between a first state and a second state. Specifically, in the first state, the multiple first mounting frames 200 are unfolded in sequence along the first direction to facilitate the absorption of solar energy and energy conversion. In the second state, the multiple first mounting frames 200 are folded in sequence and placed on the energy storage body 100 to facilitate the movement of the solar energy storage device.

[0067] The following description, using a specific application scenario, further illustrates that when the solar energy storage device is not in use, the first mounting frame 200 is folded together and placed on top of the energy storage body 100. This reduces the overall space occupied by the device and facilitates its movement. When the solar energy storage device of this application is used, the first mounting frame 200 is unfolded sequentially by the unfolding component, allowing the photovoltaic panel 300 to fully absorb solar energy. By setting the unfolding component on the energy storage body 100, this application allows the photovoltaic panel 300 to be quickly unfolded when the solar energy storage device is in use and quickly folded after use, improving the ease of use of the solar energy storage device.

[0068] Please refer to Figure 1 , Figure 2 and Figure 3 As a specific embodiment of this application, the retractable component of this application includes a plurality of first hinges 410, a plurality of first movable rods 420, a plurality of second movable rods 430, a plurality of connecting shafts 440, and a driving member 450. Adjacent first mounting frames 200 are hinged together by the first hinges 410, and after the first mounting frame 200 is unfolded, the first hinges 410 are alternately distributed vertically along the first direction.

[0069] In addition, a number of first movable rods 420 are hinged together in sequence, and a number of second movable rods 430 are hinged together in sequence. Each second movable rod 430 is corresponding to a first movable rod 420. The corresponding first movable rods 420 and second movable rods 430 are rotatably connected by a connecting shaft 440. The first movable rods 420 and second movable rods 430 are symmetrical about the connecting shaft 440. Each connecting shaft 440 is rotatably connected to the middle of one side of a first mounting frame 200 along the second direction Y.

[0070] The driving component 450 is used to drive the first movable rod 420 and the second movable rod 430 to rotate around the connecting shaft 440.

[0071] Furthermore, the maximum distance between two adjacent connecting shafts 440 is greater than the length of the first mounting frame 200 in the first direction X. This is to enable the first mounting frame 200 to unfold in parallel, so as to avoid the height difference between two adjacent first mounting frames 200 after unfolding, which would cause shadows and affect the absorption of solar energy.

[0072] Reference Figure 1 and Figure 2The retraction assembly of this application also includes a first elastic element 460. In the first state, the first elastic element 460 is installed between the first mounting frame 200 near the energy storage body 100 and the energy storage body 100, and the first elastic element 460 provides a driving force for the first mounting frame 200 to return from the first state to the second state. Here, the first elastic element 460 can be a spring or an elastic rope. In the figures of this application, it is an elastic rope. One end of the elastic rope is fixed to the top of the energy storage body 100, and the other end of the elastic rope is fixed to the side of the first mounting frame 200 closest to the energy storage body 100 along the first direction X.

[0073] Reference Figure 2 The retraction component of this application also includes a second elastic element 470. The second elastic element 470 is installed on both sides of the first mounting frame 200 along the first direction. In the first state, the second elastic element 470 provides a driving force to the two adjacent first mounting frames 200 to return from the first state to the second state.

[0074] In one embodiment, the second elastic member 470 includes a compression spring and an abutment post. A blind hole can be formed on the side of the second mounting frame, the abutment post is slidably disposed in the blind hole, one end of the compression spring is fixed to the bottom of the blind hole, and the other end of the compression spring is fixed to the abutment post. Furthermore, in order to save costs, after the first mounting frame 200 is unfolded, the second elastic member 470 can be provided on the side of the two first mounting frames 200 on both sides away from their adjacent first mounting frames 200.

[0075] Reference Figure 1 or Figure 2 or Figure 3 or Figure 4 The driving component 450 of this application includes a slide rail 451 fixed to the top of the energy storage body 100, and the slide rail 451 is arranged along a third direction. A first movable rod 420 near the slide rail 451 is hinged to the slide rail 451. A slider 452 is slidably connected to the slide rail 451 along a third direction. A second movable rod 430 near the slide rail 451 is hinged to the slider 452.

[0076] The drive unit 450 also includes a power source 453, which is used to drive the slider 452 to slide in a third direction. Specifically, the power source 453 can be a hydraulic cylinder or a screw-slide mechanism. In the figures of this application, a motor is used to drive the screw-slide mechanism to control the movement of the slider 452, and the sliders 452 of the two retracting components are driven by the same power source 453.

[0077] The following description, using a specific application scenario, further illustrates how the solar energy storage device of this application is used. By activating the power source 453, the slider 452 begins to move in a third direction. Here, the slider 452 moves towards the hinge position between the first movable block and the slide rail 451. This causes all the first movable rods 420 and the second movable rods 430 to gradually unfold, gradually increasing the distance between adjacent connecting shafts 440. Since adjacent first mounting frames 200 are hinged by the first hinge 410, and the connecting shafts 440 are rotatably connected to the first mounting frames 200, as the distance between adjacent connecting shafts 440 gradually increases, the first mounting frames 200 gradually tend towards a horizontal state until they finally reach a horizontal position. This allows the photovoltaic panels 300 to achieve a more thorough flatness and thus better absorb solar energy. As the first mounting frame approaches a horizontal state, the tension of the first elastic element 460 on the first mounting frame 200 gradually increases. Specifically, if the first elastic element 460 is an elastic rope, the tensile deformation of the elastic rope will increase. The elastic force of the second elastic element 470 on the two adjacent first mounting frames 200 also gradually increases. Specifically, when the first mounting frame 200 reaches a horizontal state, the compression spring is in a compressed state, and the elastic force of the second elastic element 470 on the two adjacent first mounting frames 200 reaches its maximum. Thus, when the first mounting frame 200 is folded, the traction of the first and second elastic elements 460 on the folding direction ensures a smoother folding process.

[0078] Reference Figure 3 , Figure 5 , Figure 6 As a specific embodiment of this application, the solar energy storage device of this application further includes two first side plates 500, which are respectively installed on both sides of the energy storage body 100 along the second direction Y. In the second state (i.e., after the first mounting frame 200 is folded), the two first side plates 500 are vertically arranged, so that the two first side plates 500 can be used to protect the photovoltaic panel 300 on both sides in the second direction Y.

[0079] Furthermore, the first side plates 500 are all hinged to the energy storage body 100.

[0080] Furthermore, refer to Figure 5 , Figure 6The solar energy storage device of this application also includes two adjustment components 600. Each adjustment component 600 is used to adjust the state of a first side plate 500. When the first mounting frame 200 switches from the second state to the first state, the adjustment component 600 is used to adjust the first side plate 500 from the vertical state to the horizontal state. In this way, the photovoltaic panel 300 can be protected after it is folded on the energy storage body 100, and the first side plate 500 can be used to avoid forming a shadow area on the photovoltaic panel 300 after it is horizontally unfolded, which would affect the efficiency of the photovoltaic panel 300 in absorbing solar energy.

[0081] Furthermore, refer to Figure 4 , Figure 5 , Figure 6 The adjustment component 600 of this application includes a first pulley 610, a second pulley 620, and a connecting rope 630. The first pulley 610 and the second pulley 620 are both installed on the side of the slide rail 451 and are correspondingly arranged in the third direction Z, that is, the first pulley 610 and the second pulley 620 are arranged vertically. One end of the connecting rope 630 is fixed to the slider 452, and the other end of the connecting rope 630 passes around the first pulley 610 and the second pulley 620 in sequence and is fixed to the first side plate 500. The fixed position of the connecting rope 630 and the first side plate 500 is far away from the hinge axis of the first side plate 500. During the process of the first mounting frame 200 switching from the first state to the second state, the distance that the slider 452 moves is equal to the length of the connecting rope 630 between the second pulley 620 and the first side plate 500.

[0082] Firstly, regarding the adjusting component 600, the design of the first pulley 610, the second pulley 620, and the connecting rope 630 in this application reduces the investment in driving equipment for the opening and closing process of the first side plate 500, lowering labor costs, and also ensures relatively stable opening and closing of the first side plate 500. For example, the adjusting component 600 could also use a motor, with a drive shaft coaxial with the axis of rotation of the first side plate 500 fixedly connected to the left and right sides of the first side plate 500. Then, by controlling the forward and reverse rotation of the motor, the forward and reverse rotation of the drive shaft is driven, thereby driving the first side plate 500 to open and close. However, this method not only requires the investment of new driving equipment but also increases the starting energy consumption of the driving equipment. Specifically, when directly driving the first side plate 500 at the drive shaft end, the driving equipment needs to overcome a large inertial torque, resulting in a large starting current, increased energy consumption, and even the inability to start due to insufficient torque. Therefore, compared to the first side plate 500, the specific design of the adjusting component 600 in this application is not only more stable for opening the first side plate 500 but also saves costs.

[0083] It should be noted that the specific position of the first pulley 610 and the second pulley 620 needs to be set accordingly. If the slider 452 moves upward and the first mounting frame 200 gradually unfolds, the first pulley 610 is located above the second pulley 620. If the slider 452 moves downward and the first mounting frame 200 gradually unfolds, the first pulley 610 is located below the second pulley 620.

[0084] It is also necessary to explain that when the first mounting frame 200 switches from the first state to the second state, the distance that the slider 452 moves is equal to the length of the connecting rope 630 between the second pulley 620 and the first side plate 500. This is achieved by using the characteristic that the ropes on both sides of the fixed pulley move the same distance, so that when the first mounting frame 200 switches from the first state to the second state, the first side plate 500 just switches from the horizontal state to the vertical state.

[0085] In one embodiment, the first side panel 500 includes a second mounting frame in which a photovoltaic panel 300 is mounted. Thus, when the first mounting frame 200 is unfolded, the second mounting frame is horizontal, and both the photovoltaic panels 300 on the first and second mounting frames can absorb solar energy, thereby improving energy storage efficiency.

[0086] It should be understood that the various forms of processes shown above can be used to rearrange, add, or delete steps. For example, the steps described in this application can be executed in parallel, sequentially, or in different orders, as long as the desired result of the technical solution of this application can be achieved, and this is not limited herein.

[0087] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, "a plurality of" means two or more, unless otherwise explicitly specified.

[0088] The above description is merely a specific embodiment of this application, but the scope of protection of this application is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in this application should be included within the scope of protection of this application. Therefore, the scope of protection of this application should be determined by the scope of the claims.
