DETAILED DESCRIPTION

[0020] In order to make the purpose, features, and advantages of this application more obvious and easy to understand, the technical solutions in the embodiments of this application will be clearly and completely described below in conjunction with the drawings in the embodiments of this application. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts shall fall within the scope of protection of this application.

[0021] The unfolding and folding of photovoltaic panels in existing solar energy storage devices are rather cumbersome and laborious.

[0022] To this end, the present application provides a solar energy storage device.

[0023] Reference Figure 1 - Figure 6 In this application, the first direction X refers to the left and right direction of the solar energy storage device, the second direction Y refers to the front and back direction of the solar energy storage device, and the third direction Z refers to the up and down direction of the solar energy storage device.

[0024] The solar energy storage device of the present application includes an energy storage body 100, with a plurality of first mounting frames 200 disposed on top of the energy storage body 100. These first mounting frames 200 are connected in sequence and 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. In addition, the solar energy storage device of the present application also includes a retractable assembly, and there are two sets of retractable assemblies, which are respectively 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 plurality of first mounting frames 200 are sequentially unfolded in the first direction to facilitate the absorption of solar energy and energy conversion. In the second state, the plurality of first mounting frames 200 are sequentially folded and placed on the energy storage body 100 to facilitate the movement of the solar energy storage device. The following is a further introduction in conjunction with specific usage scenarios. When the solar energy storage device is not in use, the first mounting frames 200 are folded together and placed on top of the energy storage body 100. This can reduce the overall space occupied by the device and facilitate the overall movement of the device. When the solar energy storage device of the present application is used, the first mounting frames 200 are driven to unfold in sequence through the folding and unfolding components, so that the photovoltaic panel 300 can fully absorb solar energy. By setting a folding and unfolding component on the energy storage body 100, the present application can quickly unfold the photovoltaic panel 300 when the solar energy storage device is in use, and can quickly fold the photovoltaic panel 300 after use, thereby improving the convenience of using the solar energy storage device.

[0025] Please refer to Figure 1 、 Figure 2 and Figure 3 As a specific implementation of the embodiment of the present application, the stowage assembly of the present 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. Two adjacent first installation frames 200 are hingedly connected by the first hinges 410, and after the first installation frames 200 are unfolded, the first hinges 410 are alternately distributed up and down along the first direction; In addition, a plurality of first movable rods 420 are hingedly connected in sequence, and a plurality of second movable rods 430 are hingedly connected in sequence, and each second movable rod 430 is provided corresponding to a first movable rod 420, and the corresponding first movable rods 420 and second movable rods 430 are rotatably connected via a connecting shaft 440, and the first movable rods 420 and the second movable rods 430 are symmetrical about the connecting shaft 440, and each connecting shaft 440 is rotatably connected to the middle portion of one side of a first installation frame 200 along the second direction Y; The driving member 450 is used to drive the first movable rod 420 and the second movable rod 430 to rotate around the connecting shaft 440 .

[0026] Furthermore, the maximum distance between two adjacent connecting axes 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 be unfolded in parallel, so as to avoid a height difference between two adjacent first mounting frames 200 after unfolding, thereby causing shadows to affect the absorption of solar energy.

[0027] Reference Figure 1 and Figure 2 The stowage assembly of the present application further includes a first elastic member 460. In the first state, the first elastic member 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 member 460 provides a driving force for the first mounting frame 200 to return from the first state to the second state. The first elastic member 460 can be a spring or an elastic cord. The figure of the present application shows an elastic cord. One end of the elastic cord is fixed to the top of the energy storage body 100, and the other end of the elastic cord is fixed to the side of the first mounting frame 200 closest to the energy storage body 100 along the first direction X.

[0028] Reference Figure 2 The expansion and retraction assembly of the present application also includes a second elastic member 470. The second elastic member 470 is installed on both sides of the first installation frame 200 along the first direction. In the first state, the second elastic member 470 provides a driving force for the two adjacent first installation frames 200 to recover from the first state to the second state.

[0029] In one embodiment, the second elastic member 470 includes a compression spring and an abutment post. A blind hole can be provided on the side of the second mounting frame. The abutment post is slidably positioned within the blind hole. One end of the compression spring is secured to the bottom of the blind hole, while the other end is secured to the abutment post. Furthermore, to save costs, after the first mounting frame 200 is deployed, the second elastic member 470 can be provided on the side of the two first mounting frames 200 located on either side, facing away from the adjacent first mounting frame 200.

[0030] Reference Figure 1 or Figure 2 or Figure 3 or Figure 4 The driving member 450 of the present application includes a slide rail 451 fixed to the top of the energy storage body 100, and the slide rail 451 is arranged along the third direction. The first movable rod 420 near the slide rail 451 is hinged to the slide rail 451, and a slider 452 is slidably connected to the slide rail 451 along the third direction. The second movable rod 430 near the slide rail 451 is hinged to the slider 452.

[0031] The driving member 450 further includes a power source 453 for driving the slider 452 to slide along the 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 drives the screw-slide mechanism to control the movement of the slider 452, and the sliders 452 of the two retracting and extending assemblies are driven by the same power source 453.

[0032] The following is a further introduction in conjunction with specific usage scenarios. When using the solar energy storage device of the present application, by turning on the power source 453, the slider 452 begins to move along the third direction. Here, the slider 452 moves in the direction close to the hinge position of the first movable block and the slide rail 451. In this way, all the first movable rods 420 and the second movable rods 430 will slowly unfold, so that the distance between the two adjacent connecting shafts 440 will gradually increase. Since the two adjacent first installation frames 200 are hinged by the first hinge 410, and the connecting shaft 440 is rotatably connected to the first installation frame 200, as the distance between the two adjacent connecting shafts 440 gradually increases, the first installation frame 200 will gradually tend to a horizontal state until it finally reaches a horizontal state, so that the photovoltaic panel 300 can be more thoroughly flattened and better absorb solar energy. As the first mounting plate approaches a horizontal position, the tension exerted by the first elastic member 460 on the first mounting frame 200 gradually increases. Specifically, if the first elastic member 460 is an elastic cord, the tensile deformation of the elastic cord increases. The elastic force exerted by the second elastic member 470 on two adjacent first mounting frames 200 also gradually increases. Specifically, when the first mounting frame 200 reaches a horizontal position, the compression spring is in a compressed state, and the elastic force exerted by the second elastic member 470 on two adjacent first mounting frames 200 reaches a maximum. In this way, when the first mounting frame 200 is folded, the traction of the first elastic member 460 and the second elastic member 470 in the folding direction of the first mounting frame 200 ensures a smoother folding process.

[0033] Reference Figure 3 、 Figure 5 、 Figure 6 As a specific implementation of an embodiment of the present application, the solar energy storage device of the present application further includes two first side panels 500, which are respectively installed on both sides of the energy storage body 100 along the second reverse direction. In the second state (i.e., after the first mounting frame 200 is folded), the two first side panels 500 are arranged vertically. In this way, the two first side panels 500 can be used to protect both sides of the photovoltaic panel 300 in the second direction Y.

[0034] Furthermore, the first side plates 500 are hinged to the energy storage body 100 .

[0035] Further, refer to Figure 5 、 Figure 6 The solar energy storage device of the present application also includes two adjustment components 600, each adjustment component 600 is used to adjust the state of a first side panel 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 panel 500 from a vertical state to a 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 panel 500 can be prevented from forming a shadow area on the photovoltaic panel 300 after the photovoltaic panel 300 is horizontally unfolded, thereby affecting the efficiency of the photovoltaic panel 300 in absorbing solar energy.

[0036] Further, refer to Figure 4 、 Figure 5 、 Figure 6 The adjustment assembly 600 of the present 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 the first pulley 610 and the second pulley 620 are correspondingly arranged in the third direction Z, that is, the first pulley 610 and the second pulley 620 are arranged up and down, one end of the connecting rope 630 is fixed to the slider 452, and the other end of the connecting rope 630 is fixed to the first side panel 500 after passing through the first pulley 610 and the second pulley 620 in sequence, and the fixing position of the connecting rope 630 and the first side panel 500 is far away from the hinge axis of the first side panel 500, wherein, during the process of switching the first mounting frame 200 from the first state to the second state, the distance moved by the slider 452 is equal to the length of the connecting rope 630 between the second pulley 620 and the first side panel 500.

[0037] First, regarding the adjustment assembly 600, the present application adopts the design of the first pulley 610, the second pulley 620, and the connecting rope 630, which can not only reduce the investment in the driving equipment during the opening and closing process of the first side panel 500 and reduce the power cost, but also ensure that the opening and closing of the first side panel 500 is relatively stable. For example, the adjustment assembly 600 can also use a motor, by fixing a drive shaft coaxial with the axis of rotation of the first side panel 500 to the left and right sides of the first side panel 500, and then controlling the forward and reverse rotation of the motor to drive the forward and reverse rotation of the drive shaft to drive the first side panel 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 driving directly at the drive shaft end of the first side panel 500, the driving equipment needs to overcome a large inertia torque, resulting in a large starting current, increased energy consumption, and even possible failure to start due to insufficient torque. Therefore, in comparison, the specific design of the adjustment assembly 600 of the present application is not only more stable for opening the first side panel 500, but also saves costs.

[0038] It should be noted here that which of the first pulley 610 and the second pulley 620 is on top needs to be set specifically. If the slider 452 moves up and the first installation frame 200 is gradually unfolded, in this case, the first pulley 610 is located above the second pulley 620; if the slider 452 moves down and the first installation frame 200 is gradually unfolded, in this case, the first pulley 610 is located below the second pulley 620.

[0039] It is also necessary to explain here that when the first installation frame 200 switches from the first state to the second state, the distance moved by the slider 452 is equal to the length of the connecting rope 630 between the second pulley 620 and the first side panel 500. This is achieved by the characteristic that the ropes on both sides of the fixed pulley move the same distance, so that when the first installation frame 200 switches from the first state to the second state, the first side panel 500 just switches from the horizontal state to the vertical state.

[0040] In one embodiment, the first side panel 500 includes a second mounting frame, within which the photovoltaic panel 300 is mounted. This allows the photovoltaic panel 300 on both the first and second mounting frames to absorb solar energy when the first mounting frame 200 is unfolded and the second mounting frame is horizontal, thereby improving energy storage efficiency.

[0041] It should be understood that the various forms of the processes shown above can be used to reorder, add, or delete steps. For example, the steps described in this application can be performed in parallel, sequentially, or in a different order, as long as the desired results of the technical solution of this application can be achieved. This is not limited herein.

[0042] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of technical features indicated. Thus, features specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of this application, "plurality" means two or more, unless otherwise specifically defined.

[0043] The above description is merely a specific embodiment of the present application, but the scope of protection of the present application is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in this application should be included in the scope of protection of this application. Therefore, the scope of protection of this application should be based on the scope of protection of the claims.
