Description

Technical Field

[0001] This utility model relates to the field of mobile phone charger technology, specifically a dual-purpose charger for solar photovoltaic panels, batteries, and flashlights. Background Technology

[0002] With the widespread use of mobile devices, smartphones, tablets and other digital products have become essential tools for people's daily life and outdoor travel. As a core accessory to ensure the battery life of devices, chargers are becoming increasingly diverse in their usage scenarios and functional requirements.

[0003] Currently, most chargers on the market are primarily single-function chargers, only able to power devices directly from the mains when plugged into a power outlet. This limitation is significant. In outdoor scenarios without mains power, such as camping, hiking, or fieldwork, these conventional chargers are completely unusable. Users must carry additional power banks to meet emergency power needs, increasing the quantity and weight of items carried and raising concerns about the inability to recharge power banks once they run out, making it difficult to guarantee device battery life during extended outdoor activities. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-purpose charger for solar photovoltaic panels, batteries, and flashlights, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A dual-purpose charger for solar photovoltaic panels, batteries, and flashlights, comprising:

[0007] The charger contains a battery, a battery management unit, and a charging control unit, which are electrically connected via wires.

[0008] The charger has a plug panel with a rotating slot on one side. A rotating plug is rotatably connected in the slot. When regular charging is needed, the rotating plug is unscrewed from the slot and inserted into the AC power socket. The charging control unit can directly convert AC power into electrical energy that meets the mobile phone charging standard to power the mobile phone.

[0009] The charger has an interface panel with multiple interfaces on the other side. When outdoors where there is no socket, the battery can be controlled by the battery management unit and the charging control unit, and the battery can be output to the mobile phone through the corresponding interface of the interface panel to provide emergency power to the mobile phone.

[0010] A solar panel mounting assembly is located on the lower end face of the charger housing and is used to mount solar panels to supply power to the battery outdoors. The solar panel mounting assembly has an adjustment structure on its side to accommodate solar panels of different sizes.

[0011] Preferably, the solar panel mounting assembly includes a fixing plate with a through hole on its upper surface. A flat-head bolt passes through the through hole and is threaded onto the lower surface of the charger housing to achieve a stable assembly between the fixing plate and the charger housing. A guide groove is provided on the front surface of the fixing plate, and a guide strip is inserted into the guide groove. The guide strip is installed on the rear surface of the movable plate, so that the movable plate can slide against the fixing plate along the extension direction of the guide groove.

[0012] Preferably, limiting angles are installed on the bottom of the upper end face of the movable plate and the top of the upper end face of the fixed plate. The limiting angles are three-sided enclosing structures that form a barrier around the side, front, and top edge of the protective shell of the solar panel. When the movable plate is pulled open and the solar panel is placed between the fixed plate and the movable plate, and then the movable plate is pushed back to its original position, the three limiting angles on the movable plate and the three limiting angles on the fixed plate will respectively fit together from the corresponding positions on both sides of the solar panel. The three-sided enclosing structure holds the solar panel in place, preventing the solar panel from shifting or falling off in the horizontal or vertical directions.

[0013] Preferably, the adjustment structure includes an elastic locking strip, the ends of which are fixedly connected to both sides of the rear end face of the movable plate, and the front end of which can be movably inserted into the through slots opened on both sides of the fixed plate. The bottom of the through slots is fixedly connected with wave teeth, and the lower end face of the elastic locking strip is fixedly connected with multiple locking teeth, which mesh with the wave teeth.

[0014] Preferably, a handle is fixedly connected to the upper end of the elastic locking strip. The handle extends vertically upward and passes through the opening at the top of the through groove, extending to the outside of both sides of the movable plate. When it is necessary to adjust the distance between the fixed plate and the movable plate, the handle is pulled upward. The handle will cause the upper end of the elastic locking strip to lift synchronously, so that the locking teeth on the lower end of the elastic locking strip disengage from the wave teeth at the bottom of the through groove. At this time, the movable plate can be easily pushed or pulled to adjust the distance. After the distance is adjusted to the target size, the handle is released. The elastic locking strip resets under its own elasticity, and the locking teeth re-engage with the wave teeth, thereby locking the relative position of the fixed plate and the movable plate again to ensure the distance is stable.

[0015] Preferably, the movable plate has a clearance groove at its front end, and an output line extends from the rear end of the solar panel. The output line is accommodated in the clearance groove to prevent it from being squeezed and damaged when the movable plate and the fixed plate are used to fix the solar panel. The end of the output line is provided with an output connector, which can be plugged into the input interface on the charger interface panel. After plugging in, the output line can transmit the electrical energy converted by the solar panel to the inside of the charger, and then form an electrical connection with the battery management unit. Under the monitoring and protection of the battery management unit, the electrical energy is stably input to the battery to replenish the battery and realize the solar charging function in outdoor scenarios.

[0016] Preferably, the upper surface of the charger housing is provided with a button and an indicator light. The button and indicator light are electrically connected to the battery management unit. When the button is pressed, the battery management unit is triggered, causing multiple indicator lights to light up and display the remaining battery power, so that the user can check the remaining power.

[0017] Preferably, a flashlight is also installed on one side of the interface panel of the charger. The flashlight is electrically connected to the battery management unit. When the button is pressed and held, a command is sent to the battery management unit, which then controls the flashlight to turn on, so as to realize the lighting function of the flashlight.

[0018] Preferably, the side of the handle is fixedly connected with anti-slip texture.

[0019] Compared with the prior art, the beneficial effects of this utility model are:

[0020] This utility model, by setting up a multi-functional structure that integrates conventional charging, emergency power supply, solar charging and flashlight lighting, not only meets the conventional charging needs in the mains power environment, but also provides emergency power supply through battery or solar power in outdoor scenarios without mains power, and can also provide lighting function, covering the needs of multiple scenarios and improving the practicality and applicability of the equipment.

[0021] This utility model provides a solar panel installation assembly consisting of a fixed plate, a movable plate, a limiting angle, and an adjustment structure. The adjustment structure allows for flexible adjustment of the distance between the fixed plate and the movable plate, accommodating solar panels of different sizes. Furthermore, the three-sided enclosure structure of the limiting angle securely fixes the solar panel, preventing it from shifting or falling off and ensuring the stability of the solar panel installation.

[0022] This utility model, by setting an elastic locking strip and cooperating with the meshing structure of wave teeth and locking teeth, allows the spacing to be adjusted by simply pulling the handle. After being released, it can automatically reset and lock. It will not disengage during daily shaking, which simplifies the installation and adjustment of solar panels and ensures the locking reliability of solar installation components.

[0034] 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.

[0035] Example 1:

[0036] Please see Figures 1 to 9 This utility model provides a technical solution:

[0037] A dual-purpose charger for solar photovoltaic panels, batteries, and flashlights, wherein the charger 1 integrates regular charging and emergency power supply, and can be connected to an external solar panel 14 for power supply.

[0038] The charger 1 is equipped with a storage battery 11, a battery management unit 12, and a charging control unit 13.

[0039] The charger 1 has a plug panel 3 with a rotating slot 301 on one side, and a rotating plug 302 is rotatably connected in the rotating slot 301 (e.g., Figure 3 (As shown).

[0040] The charger 1 has an interface panel 2 with multiple interfaces on its other side (e.g., ...). Figure 1 (As shown).

[0041] It should be noted that the interface panel 2 has at least one input interface and multiple output interfaces. When the solar panel 14 is connected to the output line 16 led out from the rear end (such as...), Figure 5 When connected to the input interface (as shown), the solar panel 14 converts the light and electrical energy into power, which is then transmitted to the charger 1. After being monitored by the battery management unit 12 and converted by the charging control unit 13, the power is stably input into the storage battery 11 for storage, thus achieving outdoor solar power replenishment. The multiple output interfaces correspond to different signal specifications (such as common interface types like USB-A and Type-C), which can be adapted to different models of charging cables, thereby providing charging support for different power-consuming devices such as mobile phones, tablets, and small digital devices, and meeting the needs of multiple devices to be powered simultaneously or individually.

[0042] In this embodiment, the charger 1 includes a charging control unit 13 and a battery management unit 12 (e.g., ...). Figure 4 As shown), the rotary plug 302 is electrically connected to the charging control unit 13. The charging control unit 13 is connected to the battery management unit 12 on one hand and to the output unit (the interface panel 2 and other parts used for external power supply) on the other hand. The battery management unit 12 is electrically connected to the battery 11.

[0043] When the rotating plug 302 is unscrewed from the slot 301 and inserted into a mains socket for regular charging, if the interface panel 2 is connected to a device such as a mobile phone via a charging cable, the charging control unit 13 can directly convert mains power into electrical energy that conforms to the mobile phone charging standard and charge the device via the output unit. When no device is connected to the interface panel 2, the charging control unit 13 will charge the battery 11 through the battery management unit 12 and store the electrical energy. When outdoors without a socket, the battery management unit 12 and the charging control unit 13 can control the battery 11 to output electrical energy to the mobile phone from the corresponding interface of the interface panel 2 via the output unit, providing emergency power to the mobile phone.

[0044] The solar mounting assembly is located on the lower end of the charger 1 housing and is used to mount the solar panel 14 to power the battery 11 outdoors. An adjustment structure is provided on its side to accommodate solar panels 14 of different sizes.

[0045] The solar panel mounting assembly includes a fixing plate 7. A through hole is formed on the upper surface of the fixing plate 7. A flat-head bolt 10 passes through the through hole and is threaded onto the lower surface of the charger 1 housing, thereby achieving a secure assembly between the fixing plate 7 and the charger 1 housing. A guide groove is formed on the front end surface of the fixing plate 7, and a guide strip 18 is inserted into the guide groove. The guide strip 18 is installed on the rear end surface of the movable plate 8, allowing the movable plate 8 to smoothly slide against the fixing plate 7 along the extension direction of the guide groove.

[0046] The bottom of the upper end face of the movable plate 8 and the top of the upper end face of the fixed plate 7 are both equipped with limit angles 9 (e.g., Figure 1 As shown), the limiting angle 9 is a three-sided enclosure structure, forming a barrier around the side, front and top edges of the protective shell 15 of the solar panel 14.

[0047] In this embodiment, when the movable plate 8 is pulled open and the solar panel 14 is placed between the fixed plate 7 and the movable plate 8, and then the movable plate 8 is pushed back to its original position, the limiting angle 9 on the movable plate 8 and the limiting angle 9 on the fixed plate 7 will fit tightly against the corresponding positions on both sides of the solar panel 14. The limiting angle 9 structure firmly holds the solar panel 14 in place, preventing the solar panel 14 from shifting or falling off in the horizontal or vertical direction, thus ensuring the stability of the installation of the solar panel 14.

[0048] It should be noted that the front end of the movable plate 8 is provided with a clearance groove 801 (e.g., Figure 3 As shown), an output line 16 (such as) is led out from the rear end face of the solar panel 14. Figure 6 As shown, the output line 16 can be accommodated in the clearance slot 801, which can prevent the output line 16 from being squeezed and damaged when the moving plate 8 and the fixed plate 7 are used to fix the solar panel 14, thus improving its service life. The output line 16 is provided with an output connector 17 at its end. The output connector 17 can be plugged into the input interface on the interface panel 2 of the charger 1. After plugging in, the output line 16 can transmit the electrical energy converted by the solar panel 14 to the inside of the charger 1, and then form an electrical connection with the battery management unit 12. Under the monitoring and protection of the battery management unit 12, the electrical energy is stably input to the storage battery 11 to replenish the storage battery 11 and realize the solar charging function in outdoor scenarios.

[0049] The adjustment structure includes an elastic locking strip 21. The ends of the elastic locking strip 21 are fixedly connected to both sides of the rear end face of the movable plate 8. The front ends of the elastic locking strip 21 can be movably inserted into the through slots 19 opened on both sides of the fixed plate 7. The bottom of the through slots 19 is fixedly connected with wave teeth 20 (e.g., Figure 8As shown, the lower end face of the elastic locking strip 21 is fixedly connected with multiple locking teeth 24, which mesh with the wave teeth 20. A handle 22 is fixedly connected to the upper end face of the elastic locking strip 21. Anti-slip texture 23 is also fixedly connected to the side of the handle 22 to increase the friction between the hand and the handle 22, facilitating operation. The handle 22 extends vertically upwards and passes through the opening at the top of the through slot 19, extending to the outer sides of both sides of the movable plate 8.

[0050] In this embodiment, when it is necessary to adjust the distance between the fixed plate 7 and the movable plate 8, pull the handles 22 on both sides upwards at the same time. The handles 22 will drive the upper end of the elastic locking strip 21 to lift synchronously, so that the locking teeth 24 on the lower end face of the elastic locking strip 21 disengages from the wave teeth 20 at the bottom of the through groove 19. At this time, the handles 22 on both sides can be easily pushed or pulled to adjust the distance between the fixed plate 7 and the movable plate 8. After the distance is adjusted to the target size, release the handles 22. The elastic locking strip 21 resets under its own elasticity, and the locking teeth 24 re-engages with the wave teeth 20, thereby locking the relative position of the fixed plate 7 and the movable plate 8 again, ensuring the distance is stable, so as to adapt to the installation of solar panels 14 of different sizes. The structure is simple and the operation is convenient.

[0051] It should be noted that the elastic locking strip 21 is preferably made of a material with good elasticity and toughness, such as thermoplastic elastomer (TPE). This type of material can produce a stretchable deformation when subjected to tension, causing the locking teeth 24 and the wave teeth 20 to disengage. When the external force is removed, it can quickly return to its original shape due to its own toughness, allowing the locking teeth 24 to re-engage stably with the wave teeth 20. Deformation and disengagement will only occur when the handle 22 is pulled manually. Even if subjected to external forces such as shaking during daily use, it will not easily disengage, ensuring the reliability of the distance locking between the fixed plate 7 and the moving plate 8, and providing stable support for the installation of the solar panel 14.

[0052] Example 2:

[0053] Please see Figure 10 This utility model provides a technical solution:

[0054] The upper surface of the charger 1 casing is equipped with a button 4 and multiple indicator lights 5. The button 4 and indicator lights 5 are electrically connected to the battery management unit 12. When the button 4 is pressed, the battery management unit 12 is triggered, causing the multiple indicator lights 5 to light up. The remaining power of the battery 11 is displayed intuitively through different combinations of light 5 (such as the number of lights, colors, etc.), so that the user can check the remaining power.

[0055] like Figure 10As shown, a flashlight 25 can also be installed on one side of the interface panel 2 of the charger 1. The flashlight 25 is electrically connected to the battery management unit 12. When the button 4 is pressed and held, a command is sent to the battery management unit 12 to supply power through the battery 11 and control the flashlight 25 to light up, so as to realize the lighting function of the flashlight and meet the user's lighting needs in dark environments.

[0056] It should be noted that the setting of indicator light 5, button 4 and flashlight are conventional technical means in this field, and their specific circuit connection structure and signal transmission logic have been disclosed in existing related technologies, so there is no need to elaborate here.

[0057] In summary, when using this utility model, it can be connected to the mains power via the rotating plug 302 to directly charge the device or replenish the battery 11; when there is no mains power outdoors, the solar panel 14 can be connected to the charger 1 via the input interface to convert solar energy into electrical energy and store it in the battery 11; the battery 11 can also provide emergency power to mobile phones and other devices through the output interface; pressing and holding the button 4 can also turn on the flashlight 25 for illumination, and pressing the button 4 can check the remaining power of the battery 11. It has multiple functions and is easy to use.

[0058] All other parts of this utility model not described herein are the same as existing technologies, or are known technologies, or can be implemented using existing technologies, and will not be described in detail here.

[0059] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
