Description

Technical Field

[0001] This utility model relates to the field of new energy, and in particular to a foldable solar electronic charging panel. Background Technology

[0002] With increasing emphasis on environmentally friendly energy and the widespread use of mobile electronic devices, foldable solar charging panels, as portable devices that can charge devices using solar energy, have received growing attention. They provide a convenient charging solution for people in outdoor environments where traditional power sources are unavailable, allowing them to charge electronic devices such as mobile phones and tablets whether camping, hiking, or working in the field.

[0003] However, existing foldable solar charging panels still have some problems in practical use. After unfolding, their structural stability is insufficient, and they are prone to changes in unfolding angle when subjected to wind or other external forces. Especially when the unfolding angle decreases, it severely impacts the solar energy collection efficiency, which is closely related to the angle at which the panel receives sunlight. When the unfolding angle of the foldable solar charging panel changes, particularly when it decreases, both the area and angle at which the solar photovoltaic panel receives sunlight change adversely, leading to reduced solar energy absorption and thus lower efficiency in converting light energy into electrical energy. This means that the charging speed for energy storage devices will slow down, and may even fail to meet the power needs of electronic devices, affecting the user's normal operating experience.

[0004] Therefore, in order to improve the performance and practicality of foldable solar electronic charging panels, it is necessary to improve them and design an effective angle locking device to ensure that the charging panel can stably maintain the optimal unfolding angle during use, so as to improve the solar energy collection efficiency and meet the user's needs in various environments. Utility Model Content

[0005] The main purpose of this invention is to propose a foldable solar electronic charging panel, which aims to solve the problem that the foldable solar electronic charging panel has insufficient structural stability after being unfolded and used. When subjected to wind or other external forces, the unfolded foldable solar electronic charging panel is prone to changes in its unfolding angle. In particular, when the unfolding angle becomes smaller, it will seriously affect the solar energy collection effect of the foldable solar electronic charging panel.

[0006] To address the aforementioned problems, this utility model proposes a foldable solar electronic charging panel, comprising a rectangular shell A and a rectangular shell B disposed on the left side of the rectangular shell A. The outer wall of the left end of the rectangular shell A has multiple concave hinge grooves A, and the outer wall of the right end of the rectangular shell B has multiple concave hinge grooves B. Each hinge groove A corresponds to one hinge groove B. Rotating hinges connect the hinge grooves A and B, and these rotating hinges are fixedly connected to the rectangular shell A and rectangular shell B respectively by screws. The rectangular shell A and rectangular shell B can rotate clockwise and counterclockwise via the multiple rotating hinges. An angle locking device is connected to the top of the rectangular shell A and rectangular shell B.

[0007] In one embodiment, the angle locking device includes a metal fixing block, a metal rotating connecting strip B, a connecting screw, and a metal rotating connecting strip A. The metal fixing block is fixed to the right side of the center of the outer wall at the top of the rectangular shell plate B. The metal rotating connecting strip B is fixed to the outer wall of the right end of the upper half of the metal fixing block. The metal rotating connecting strip A is fixed to the left side of the center of the outer wall at the top of the rectangular shell plate A. The left end of the metal rotating connecting strip A and the right end of the metal rotating connecting strip B are both located above the connection between the rectangular shell plate A and the rectangular shell plate B. The connecting screw is fixed to the top of the left end of the metal rotating connecting strip A. The connecting screw and the metal rotating connecting strip A are fixedly connected by welding. The upper half of the circular outer wall of the connecting screw is threaded, while the lower half of the circular outer wall of the connecting screw is a smooth outer wall.

[0008] In one embodiment, the angle locking device further includes an internal threaded locking sleeve, a rotating rod, and a screw rotating hole. The right end of the metal rotating connecting strip B is provided with a screw rotating hole, and the screw rotating hole is sleeved on the outside of the connecting screw. The outside of the connecting screw is also threaded with an internal threaded locking sleeve, and the internal threaded locking sleeve is located on the upper side of the top outer wall of the metal rotating connecting strip B. The circular outer wall of the internal threaded locking sleeve is provided with multiple rotating rods.

[0009] In one embodiment, the metal rotating connecting strip A is attached to the bottom of the metal rotating connecting strip B, the metal rotating connecting strip A and the metal rotating connecting strip B are rotatable relative to each other, and the metal rotating connecting strip A can rotate to the bottom of the metal rotating connecting strip B, and the connecting screw can rotate clockwise and counterclockwise in the screw hole.

[0010] In one embodiment, the rotating rod can drive the internal threaded locking sleeve to rotate clockwise and counterclockwise. The clockwise and counterclockwise rotation of the internal threaded locking sleeve can move up and down outside the connecting screw through the action of the thread. The center of the connecting screw coincides with the rotation center point of multiple rotating hinges.

[0011] In one embodiment, both rectangular shell plate A and rectangular shell plate B have rearwardly recessed integrated grooves at their front ends, and solar photovoltaic panels are disposed in both integrated grooves. The two solar photovoltaic panels are electrically connected to each other through a flexible conductive sheet.

[0012] In one embodiment, a rectangular groove B is provided inside the left end of the rectangular shell plate B, and a rectangular groove A is provided inside the right end of the rectangular shell plate A. Both the rectangular groove A and the rectangular groove B have their openings facing forward. A closed magnetic strip is fixed inside the rectangular groove B, and a magnetic strip is fixed inside the rectangular groove A.

[0013] In one embodiment, the rectangular shell plate A and the rectangular shell plate B can be rotated to a closed state by multiple rotating hinges. When the rectangular shell plate A and the rectangular shell plate B are rotated so that their front outer walls are in contact with each other, the closing fixing magnetic strip and the attracting magnetic strip are magnetically attracted together. The right outer wall of the rectangular shell plate A and the left outer wall of the rectangular shell plate B are both provided with portable handles.

[0014] In one embodiment, a flat energy storage battery box is fixed to the outer wall of the rear end of the rectangular shell plate A, and a converter is fixed to the bottom end of the flat energy storage battery box. The converter is electrically connected to the solar photovoltaic panel through a flexible conductive sheet, and the flat energy storage battery box is electrically connected to the converter through wires. Multiple discharge ports are provided inside the top of the flat energy storage battery box.

[0015] In one embodiment, bracket corner sleeves are fixed to the outer wall of the upper right rear end of rectangular shell plate A and the outer wall of the upper left rear end of rectangular shell plate B. An inclined placement bracket is inserted into each of the two bracket corner sleeves. The top of the inclined placement bracket is rotatably connected to the bracket corner sleeve through a damping pivot. U-shaped storage fixing clips are fixed to the outer walls of the rear ends of rectangular shell plate A and rectangular shell plate B. The U-shaped storage fixing clips can be elastically snapped onto the outside of the inclined placement bracket.

[0016] Beneficial Effects: The technical solution of this utility model adds a novel angle locking device to the top of the rectangular shells A and B of the foldable solar electronic charging panel. After the rectangular shells A and B are rotated and unfolded via multiple rotating hinges, the angle locking device can lock the unfolding angle between the rectangular shells A and B, preventing the unfolding angle of the rectangular shells A and B from easily changing due to wind or other external forces during the unfolding and use of the foldable solar electronic charging panel. Furthermore, the angle locking device has an ingenious structural design and is easy to operate. The rotatable engagement of the metal rotating connecting strips A and B, and the flexible rotation of the connecting screw in the screw hole, ensure that the rectangular shells A and B remain stable during the unfolding process. The angle can be smoothly adjusted to the required angle, and the rotation rod drives the internal thread locking sleeve to move up and down on the connecting screw, which can quickly and firmly lock the unfolding angle. Compared with the traditional complex locking structure, this locking method not only reduces the number of parts and lowers the cost, but also improves the reliability of locking. In different usage scenarios, users can flexibly adjust the unfolding angle of rectangular shell A and rectangular shell B according to actual needs, such as the angle of sunlight and placement position, and then fix them precisely through the angle locking device. For example, when used outdoors, the angle of the charging panel can be adjusted according to the direction of the sun to obtain the best sunlight, improve the light energy conversion efficiency of the solar photovoltaic panel, thereby increasing the charging amount of the flat energy storage battery box and providing more power for electronic devices connected to the discharge socket.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

For example, "fixing" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] Furthermore, if the embodiments of this utility model involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the meaning of "and / or" throughout the text includes three parallel solutions; for example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0030] This utility model provides, for example Figure 1-6 The foldable solar charging panel shown includes a rectangular shell A1 and a rectangular shell B2 located on the left side of the rectangular shell A1. The outer wall of the left end of the rectangular shell A1 has multiple recessed hinge grooves A8, and the outer wall of the right end of the rectangular shell B2 has multiple recessed hinge grooves B9. Each hinge groove A8 corresponds to one of the multiple hinge grooves B9. Rotating hinges 11 connect the hinge grooves A8 and B9, and are fixedly connected to the rectangular shell A1 and rectangular shell B2 by screws. The rectangular shell A1 and rectangular shell B2 can rotate clockwise and counterclockwise via the multiple rotating hinges 11. This novel foldable solar charging panel uses a combination design of rectangular shell A1 and rectangular shell B2, and through multiple one-to-one... Rotating hinges 11 are installed in the corresponding hinge grooves A8 and B9, allowing rectangular shell plates A1 and B2 to rotate flexibly clockwise and counterclockwise. This design provides the charging plate with a foldable feature, making it convenient to carry and use in different scenarios. Both rectangular shell plates A1 and B2 have rearwardly recessed integrated grooves 3 at their front ends. Solar photovoltaic panels 4 are installed in both integrated grooves 3. The two solar photovoltaic panels 4 are electrically connected by a flexible conductive sheet. The design of fixing the solar photovoltaic panels 4 in the integrated grooves 3 not only protects the solar photovoltaic panels 4, but also allows the photovoltaic panels to be fully exposed to sunlight when unfolded, so as to absorb solar energy and convert it into electrical energy. Furthermore, the electrical connection between the two solar photovoltaic panels 4 by the flexible conductive sheet ensures that electrical energy can be transmitted smoothly.

[0031] like Figure 1 and Figure 2As shown, a rectangular groove B6 is provided inside the left end of the rectangular shell plate B2, and a rectangular groove A13 is provided inside the right end of the rectangular shell plate A1. Both rectangular grooves A13 and B6 have their openings facing forward. A closing magnetic strip 7 is fixed inside the rectangular groove B6, and a magnetic strip 12 is fixed inside the rectangular groove A13. The rectangular shell plates A1 and B2 can be rotated to a closed state by multiple rotating hinges 11. The rotation of the rectangular shell plates A1 and B2 by the rotating hinges 11 allows the charging plate to be freely switched between unfolded use and closed storage. When the charging plate is needed, it can be unfolded to obtain a larger light-receiving area. When storing or carrying, it can be rotated to close, reducing the space occupied. When the rectangular shell A1 and rectangular shell B2 are rotated so that their front outer walls are in contact with each other, the closing fixing magnetic strip 7 and the magnetic strip 12 are magnetically attracted together. The right outer wall of the rectangular shell A1 and the left outer wall of the rectangular shell B2 are both provided with portable handles 5. When the rectangular shell A1 and rectangular shell B2 are rotated to their front outer walls in contact with each other, the closing fixing magnetic strip 7 in the rectangular groove B6 and the magnetic strip 12 in the rectangular groove A13 are magnetically attracted together, thus firmly closing the two together. This magnetic closing method is simple to operate and can effectively prevent the charging pad from accidentally unfolding during carrying.

[0032] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a flat energy storage battery box 14 is fixed to the outer wall of the rear end of a rectangular shell plate A1. A converter 15 is fixed to the bottom of the flat energy storage battery box 14. The converter 15 is electrically connected to the solar photovoltaic panel 4 through a flexible conductive sheet. The flat energy storage battery box 14 is electrically connected to the converter 15 through wires. Multiple discharge ports 19 are provided inside the top of the flat energy storage battery box 14. The converter 15, fixed to the bottom of the flat energy storage battery box 14, is electrically connected to the solar photovoltaic panel 4 through a flexible conductive sheet. Its function is to convert the electrical energy generated by the solar photovoltaic panel 4 to meet the charging requirements of the flat energy storage battery box 14, realizing the conversion process from solar energy to electrical energy and then to storable electrical energy. The electrical energy converted by the converter 15 is stored in the flat energy storage battery box 14. The multiple discharge ports 19 provided inside the top of the flat energy storage battery box 14 can provide 5V 1A / 5V 2A / 12V. It offers multiple DC power outputs, including 2A, providing charging interfaces for various electronic devices and enabling the output of stored electrical energy to meet users' needs for charging electronic devices in different scenarios.

[0033] like Figure 1 , Figure 3 and Figure 4As shown, bracket corner sleeves 18 are fixed to the outer wall of the upper right rear end of rectangular shell A1 and the outer wall of the upper left rear end of rectangular shell B2. An inclined placement bracket 17 is inserted into each of the two bracket corner sleeves 18. The top of the inclined placement bracket 17 is rotatably connected to the bracket corner sleeve 18 through a damping pivot. U-shaped storage fixing clips 16 are fixed to the outer walls of the rear ends of rectangular shell A1 and rectangular shell B2. The U-shaped storage fixing clips 16 can be elastically snapped onto the outside of the inclined placement bracket 17. The design of the inclined placement bracket 17 allows users to adjust the tilt angle of the charging board according to actual needs to obtain better lighting conditions. At the same time, the U-shaped storage fixing clips 16 fixed to the outer walls of the rear ends of rectangular shell A1 and rectangular shell B2 can be elastically snapped onto the outside of the inclined placement bracket 17. When the inclined placement bracket 17 is not in use, it can be fixed to the rear end of the charging board to avoid loss and make the overall structure more compact and orderly.

[0034] like Figure 1 , Figure 5 and Figure 6 As shown, an angle locking device 10 is connected to the top of rectangular shell plate A1 and rectangular shell plate B2. The angle locking device 10 includes a metal fixing block 20, a metal rotating connecting strip B21, a connecting screw 23, and a metal rotating connecting strip A25. The metal fixing block 20 is fixed to the right side of the center of the outer wall at the top of the rectangular shell plate B2. The metal rotating connecting strip B21 is fixed to the outer wall of the upper right end of the metal fixing block 20. The metal rotating connecting strip A25 is fixed to the left side of the center of the outer wall at the top of the rectangular shell plate A1. The left end of the metal rotating connecting strip A25 and the right end of the metal rotating connecting strip B21 are both located above the connection between the rectangular shell plate A1 and the rectangular shell plate B2. The connecting screw 23 is fixed to the top of the left end of the metal rotating connecting strip A25. The metal fixing block 20 is fixed to the right side of the center of the outer wall at the top of the rectangular shell plate B2, providing a stable installation base for the angle locking device 10. The metal rotating connecting strip B21 is fixed to the outer wall of the upper right end of the metal fixing block 20. Strip B21 cooperates with metal rotating connecting strip A25 fixed on the left side of the center of the top outer wall of rectangular shell plate A1. The left end of metal rotating connecting strip A25 and the right end of metal rotating connecting strip B21 are both located on the upper side of the connection between rectangular shell plate A1 and rectangular shell plate B2. This layout allows the two rotating connecting strips to perform related actions around the connection between rectangular shell plate A1 and rectangular shell plate B2. The connecting screw 23 fixed at the top left end of metal rotating connecting strip A25 becomes the key connecting component for realizing the angle locking function. The connecting screw 23 and metal rotating connecting strip A25 are fixedly connected by welding. The upper half of the circular outer wall of the connecting screw 23 is threaded, while the lower half of the circular outer wall of the connecting screw 23 is smooth. The screw hole 26 is sleeved on the outside of the smooth outer wall of the lower half of the connecting screw 23. The contact between the smooth outer wall and the screw hole 26 can reduce the friction between the two, thereby reducing the degree of wear between them.

[0035] like Figure 1 , Figure 5 and Figure 6 As shown, the angle locking device 10 also includes an internal thread locking sleeve 22, a rotating rod 24, and a screw rotating hole 26. The right end of the metal rotating connecting bar B21 has a screw rotating hole 26 inside, and the screw rotating hole 26 is sleeved on the outside of the connecting screw 23. An internal thread locking sleeve 22 is also threaded onto the outside of the connecting screw 23, and the internal thread locking sleeve 22 is located on the upper side of the top outer wall of the metal rotating connecting bar B21. Multiple rotating rods 24 are provided on the circular outer wall of the internal thread locking sleeve 22. The metal rotating connecting bar A25 is attached to the bottom of the metal rotating connecting bar B21, and the metal rotating connecting bar A25 and the metal rotating connecting bar B21 can rotate relative to each other. 5. The metal rotating connecting strip B21 can be rotated to the bottom. The connecting screw 23 can rotate clockwise and counterclockwise in the screw hole 26. The metal rotating connecting strip A25 is attached to the bottom of the metal rotating connecting strip B21. The two can rotate relative to each other. This rotational relationship provides flexibility for adjusting the angle between the rectangular shell plate A1 and the rectangular shell plate B2. The screw hole 26 provided inside the right end of the metal rotating connecting strip B21 is sleeved on the outside of the connecting screw 23. The connecting screw 23 can rotate clockwise and counterclockwise in the screw hole 26, so that the metal rotating connecting strip A25 and the metal rotating connecting strip B21 can rotate relative to each other, thereby adjusting the included angle between the rectangular shell plate A1 and the rectangular shell plate B2.

[0036] like Figure 1 , Figure 5 and Figure 6As shown, the rotating rod 24 can drive the internal thread locking sleeve 22 to rotate clockwise and counterclockwise. The clockwise and counterclockwise rotation of the internal thread locking sleeve 22 can move up and down outside the connecting screw 23 through the action of the thread. The center of the connecting screw 23 coincides with the rotation center point of multiple rotating hinges 11. This design point is crucial. It ensures that during the adjustment of the angle between rectangular shell A1 and rectangular shell B2, the action of the angle locking device 10 is coordinated with the rotation action of the rotating hinges 11. This ensures that when unfolding or folding the charging pad, the angle locking device 10 will not interfere with the normal rotation of the rotating hinges 11, and can accurately fix the position of rectangular shell A1 and rectangular shell B2 when locking the angle, ensuring that the charging pad can be used in various usage scenarios. To stably maintain the required unfolding angle, when it is necessary to lock the angle between rectangular shell plate A1 and rectangular shell plate B2, the rotating rod 24 drives the internal thread locking sleeve 22 to rotate clockwise and counterclockwise. Since the internal thread locking sleeve 22 and the connecting screw 23 are threadedly connected, the internal thread locking sleeve 22 can move up and down outside the connecting screw 23 through the thread action when rotating clockwise and counterclockwise. When the internal thread locking sleeve 22 moves downward and tightly abuts against the outer wall of the top of the metal rotating connecting bar B21, the rotation of the connecting screw 23 and the metal rotating connecting bar A25 is restricted, thereby locking the relative position of the metal rotating connecting bar A25 and the metal rotating connecting bar B21, and thus locking the unfolding angle between rectangular shell plate A1 and rectangular shell plate B2.

[0037] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
