[0041] It should be noted that the terms "first," "source domain," "third," etc., used in the claims, specification, and drawings of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. Such data are interchangeable where appropriate so that the embodiments of this application described herein can be implemented in a sequence other than that shown or described herein. Furthermore, the terms "comprising," "having," and their variations are intended to cover non-exclusive inclusion; for example, a process, method, system, product, or apparatus that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products, or apparatuses.

[0042] To facilitate understanding of the various embodiments of this application, the application background of the embodiments will be explained.

[0043] Most existing solar lights adopt an integrated design, with the output adapter tightly integrated with the internal components of the solar light. While this improves the overall integrity of the product, it also introduces limitations in maintenance. If any output adapter malfunctions, the entire lighting system often becomes unusable. This design, to some extent, affects the product's sustainability and lifespan, increasing replacement costs for users.

[0044] This application provides an off-grid solar charging lamp, including: a first housing, a second housing, a lighting source, an input device, an output adapter, and a circuit board.

[0045] The first housing and the second housing are fitted together to form a lamp body. The lamp body contains the lighting source and the circuit board. The lighting source transmits light through the second housing. The input device includes an input port and an energy storage element. The input port is located on the end side of the lamp body and transmits electrical energy to the energy storage element for storage when it is plugged into a power supply. The energy storage element provides electrical energy to the lighting source through the circuit board.

[0046] The lamp body has a mounting slot at one end, and the output adapter is located in the mounting slot. The output adapter includes a detachable adapter plate, a cover plate, and an output adapter component. The detachable adapter plate includes a power adapter and an electrical connection component. One end of the power adapter is plugged into a power supply terminal on the circuit board, and the other end is electrically connected to the electrical connection component. The output adapter component includes a wire, an input terminal, and an output adapter terminal. The input terminal is electrically connected to the electrical connection component through one end of the wire. The other end of the wire is connected to the output adapter terminal, and the output adapter terminal is plugged into the device to be charged to charge the device.

[0047] The cover plate is matched and installed with the mounting groove and covers the mounting groove, and the detachable adapter plate is installed between the cover plate and the mounting groove.

[0048] The following combination Figures 1-11 This article provides a detailed introduction to off-grid solar charging lights.

[0049] Please see Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the overall structure of the off-grid solar charging lamp provided in this application. Figure 2This is a first structural schematic diagram of one end of the off-grid solar charging lamp provided in this application. The off-grid solar charging lamp includes: a first housing 10, a second housing 20, a lighting source, an input device, an output adapter, and a circuit board. The first housing 10 and the second housing 20 are fitted together to form the lamp body. In specific implementations, the first housing 10 and the second housing 20 can be fitted together in various ways to form the lamp body. One way is that the first housing 10 and the second housing 20 are fitted together by a snap-fit ​​mechanism. For example, the first housing 10 has multiple positioning holes, and positioning grooves are provided at preset positions of the positioning holes. The second housing 20 has positioning posts that match the multiple positioning holes, and positioning protrusions are provided at preset positions of the positioning posts, with the positioning protrusions elastically connected to the positioning posts. When the first housing 10 and the second housing 20 are engaged, the positioning pin extends into the corresponding positioning hole. At this time, the positioning protrusion is in a compressed state. As the positioning pin continues to extend, when the positioning protrusion is at the same depth as the positioning groove at the preset position, the positioning protrusion is in an extended state and extends into the positioning groove, thereby completing the engagement of the first housing 10 and the second housing 20. Another method is to fix the first housing 10 and the second housing 20 to form a lamp body by fixing screws. For example, multiple threaded holes can be provided on the first housing 10, and multiple fixing holes corresponding to the threaded holes can be provided on the second housing 20. By inserting fixing screws into the fixing holes and threaded holes, the first housing 10 and the second housing 20 are fixedly connected. Of course, the first housing 10 and the second housing 20 can also be installed in other ways, all of which are within the protection scope of this application.

[0050] Inside the lamp body, there is also a lighting source and a circuit board. The lighting source transmits light through the second housing 20, which is a transparent housing to facilitate light transmission. Please continue reading. Figure 2 The input device includes an input port 101 and an energy storage element (not shown in the figure). The energy storage element can be a rechargeable battery. The input port 101 is located on the end side of the lamp body and transmits electrical energy to the energy storage element for storage when it is plugged into a power supply. The energy storage element provides electrical energy to the lighting source through the circuit board. The input port can not only charge but also transmit data.

[0051] Please see Figure 5 and Figure 6 , Figure 5 This is a schematic diagram of the structure of the off-grid solar charging lamp guide channel and receiving channel provided in this application. Figure 6This is a partially enlarged structural diagram of the mounting slot for the off-grid solar charging lamp provided in this application. A mounting slot 30 is provided at one end of the lamp body, and an output adapter is installed in the mounting slot 30. The output adapter includes a detachable adapter plate 202, a cover plate 201, and an output adapter component. The cover plate 201 is fitted and installed to cover the mounting slot 30. The detachable adapter plate 202 is installed between the cover plate 201 and the mounting slot 30. Specifically, the cover plate 201 can also be a transparent cover plate. The mounting slot 30 is located on the end side near the input port 101, and the opening direction of the mounting slot 30 is on the same side as the lighting direction of the light source. It should be noted that placing the mounting slot 30 on the end side near the input port 101 makes the internal wiring layout more convenient. Of course, the mounting slot 30 can also be placed on the end side away from the input port 101.

[0052] Please see Figure 7 and Figure 8 , Figure 7 This is a first structural schematic diagram of the detachable adapter plate for the off-grid solar charging lamp provided in this application. Figure 8 This is a second structural schematic diagram of the detachable adapter plate for an off-grid solar charging lamp provided in this application. In this embodiment, the detachable adapter plate 202 includes a power adapter 203 and an electrical connection component. One end of the power adapter 203 is plugged into a power supply terminal 206 on the circuit board, and the other end is electrically connected to the electrical connection component. The output adapter component includes a wire, an input terminal, and an output adapter terminal. The input terminal is electrically connected to the electrical connection component through one end of the wire; the other end of the wire is connected to the output adapter terminal, which is plugged into the device to be charged to charge the device. It should be noted that this output adapter terminal not only charges but also has data transmission functionality.

[0053] Please continue reading Figure 7 One end of the power adapter 203 is connected to the detachable adapter plate 202, and the other end extends toward the circuit board 208. Please refer to [link / reference]. Figure 9 , Figure 9This is a schematic diagram of the power adapter for an off-grid solar charging lamp provided in this application. One end of the power adapter 203 is connected to the detachable adapter plate 202, and the other end extends towards the circuit board 208. The end of the power adapter 203 facing the circuit board 208 has an elastically deformable, slit-like structure. Under the action of the elastic deformation, the power supply terminal 206 is inserted into the power adapter 203. After the elastic deformation is restored, the power supply terminal 206 is covered by the power adapter 203, achieving an electrical connection. The end of the power adapter 203 connected to the detachable adapter plate 202 passes through the detachable adapter plate 202 and is electrically connected to the electrical connection component. It should be noted that by setting the elastically deformable, slit-like structure, the power adapter can more firmly fix the power supply terminal, thereby ensuring a more reliable electrical connection between the power adapter and the power supply terminal on the circuit board.

[0054] In practical applications, the power supply end can be a pin, and specifically includes a positive pin, a negative pin, and a signal pin. The bottom of the positive pin, the negative pin, and the signal pin are electrically connected to the circuit board. The positive pin, the negative pin, and the signal pin are covered by a power adapter, and the power adapter is electrically connected to a detachable adapter board.

[0055] Please continue reading Figure 1 , Figure 3 and Figure 7 In this embodiment of the application, the output adapter component includes a detachable output adapter component 40 and a fixed output adapter component 50. The electrical connection component includes a first electrical connection component 204 and a second electrical connection component 205.

[0056] The fixed output adapter 50 includes: a first wire and a first output adapter 501; one end of the first wire is connected to one end of the first electrical connection component 204, and the other end of the first wire is connected to the power adapter 203; one end of the first electrical connection component 204 is located between the detachable adapter plate 202 and the circuit board 208, and the other end of the first electrical connection component 204 is electrically connected to the first output adapter 501; the first output adapter 501 is located between the detachable adapter plate 202 and the cover plate 201, and has a port of the first output adapter 501 exposed to the outside of the lamp body; the port of the first output adapter 501 faces the length direction of the lamp body; the port of the first output adapter 501 is plugged into the device to be charged to charge the device. In specific implementation, the port of the first output adapter 501 can be a USB port, and the number of ports of the first output adapter 501 can be one, two or more, which can be set according to actual needs. In this embodiment, the first output adapter 501 has two ports and the ports of the first output adapter 501 face the length direction of the lamp body as an example. In specific implementation, the orientation of the ports of the first output adapter 501 can also be set according to actual needs, for example, it can also face the width direction of the lamp body.

[0057] Please see Figure 3 , Figure 4 and Figure 8 , Figure 3 This is a schematic diagram of the second structure of one end of the off-grid solar charging lamp provided in this application. Figure 4 This is a structural schematic diagram of the detachable output adapter component for the off-grid solar charging lamp provided in this application. Figure 8This is a second structural schematic diagram of the detachable adapter plate for an off-grid solar charging lamp provided in this application. The detachable output adapter component 40 includes: a second wire 402 and a second output adapter terminal 401; the plug-in terminal 403 of the second wire 402 is pluggably connected to the second electrical connection component 205 through a plug-in hole 405 exposed outside the lamp body, and the second electrical connection component 205 is located between the detachable adapter plate 202 and the circuit board 208; the connection end of the second wire 402 is connected to the second output adapter terminal 401; the contact end 2053 of the second electrical connection component 205 located between the detachable adapter plate 202 and the cover plate 201 is electrically connected to the power adapter component 203; the second output adapter terminal 401 and the second wire 402 are exposed outside the lamp body; the plug-in terminal 403 is plugged into the second electrical connection component 205; the port of the second output adapter terminal 401 is plugged into the device to be charged to charge the device. In specific implementation, the plug-in terminal 403 can be configured as a pin structure, and the second output adapter terminal 401 can be a Type-C interface or a Micro USB interface. Of course, the number of second output adapter terminals can be set according to actual needs. The second output adapter terminals and the plug-in terminals are arranged opposite each other along the width direction of the lamp body. In this embodiment, the number of second output adapter terminals is two, the number of plug-in terminals is two, and the second output adapter terminals and the plug-in terminals are arranged opposite each other along the width direction of the lamp body as an example. In specific implementation, the number and orientation of the second output adapter terminals can be set according to actual needs.

[0058] It should be noted that as the ports of the first and second output adapters are repeatedly connected to the devices to be charged, these ports are prone to damage. In this embodiment, since the port of the first output adapter is located on a detachable adapter plate, when the port of the first output adapter is damaged, it can be replaced by disassembling the detachable adapter plate. When the port of the second output adapter is damaged, the plug end of the second wire can be directly removed from the plug hole to replace the detachable output adapter component, thereby replacing the port of the second output adapter. This extends the overall service life of the product and reduces the replacement cost for users. Furthermore, the availability of multiple types of output adapter ports allows for compatibility with various devices to be charged, broadening the application range of off-grid solar charging lights.

[0059] Please continue reading Figure 8In this embodiment, the second electrical connection component 205 includes: a first electrical contact 2051 located below the detachable adapter plate 202, a second electrical contact 2052, a contact end 2053 located above the detachable adapter plate 202, and a connector 2054 connected to the lower part of the detachable adapter plate; the first electrical contact 2051 and the second electrical contact 2052 extend from both ends of the connector 2054 toward the circuit board 208 and meander toward the detachable adapter plate 202, forming an elastically deformable contact space between them, which can cover the plug end 403 under the elastic deformation; the contact end 2053 extends horizontally along one side of the connector 2054 and extends through the detachable adapter plate 202 toward the cover plate 201.

[0060] It should be noted that after the first and second electrical contacts extend from opposite ends of the connector toward the circuit board and meander toward the detachable adapter plate, an elastically deformable contact space is formed between them. Under the action of elastic deformation, the plug end of the second wire is covered in this contact space, thereby achieving electrical connection. In specific implementation, there are two second electrical connection components, symmetrically arranged on the detachable adapter plate. When the detachable output adapter component achieves electrical connection, it is achieved by electrically connecting the pin structure of the plug end with the elastically deformable contact space formed between the first and second electrical contacts, and the plug end and the contact space are matched and correspondingly arranged.

[0061] Please continue reading Figure 2 and Figure 4 In this embodiment, the cover plate 201 is further provided with a receiving groove 2011, which is used to receive the second output adapter 401, such that the port of the second output adapter 401 faces the width direction of the lamp body; and the upper surface of the second output adapter 401 located in the receiving groove 2011 is on the same plane as the second housing 20; on the same side of the mounting groove 30, the insertion direction of the plug hole provided on the outside of the lamp body is opposite to the orientation of the port of the second output adapter 401, and the second wire can be embedded in the guide groove 404 provided on the lamp body and extend along the guide groove 404 into the receiving groove 2011, and the surface of the second wire 402 is on the same plane as the lamp body. Please refer to Figure 10 , Figure 10This is a partially enlarged structural diagram of the cover plate of the off-grid solar charging lamp provided in this application. A limiting plate 2012 is provided within the receiving groove 2011 along the width direction of the lamp body. Fixing structures 2013 for fixing the second output adapter 401 are provided on both sides of the limiting plate 2012 and / or on both sides of the receiving groove 2011 along the length direction of the lamp body. The fixing structure 2013 consists of continuous or discrete raised anti-slip strips and / or dotted protrusions. It should be noted that by providing the fixing structure, when the second output adapter is placed in the receiving groove, the fixing structure will generate friction on the second output adapter. Under the action of friction, the second output adapter can be more securely placed in the receiving groove, preventing it from falling out.

[0062] Please continue reading Figure 7 In this embodiment, the bottom of the power supply terminal 206 is electrically connected to the circuit board 208, and a waterproof sealing ring 207 is nested at the bottom of the power supply terminal 206. By providing the waterproof sealing ring, the circuit board is protected from water immersion when water enters the lamp body. A waterproof sealing strip is provided between the first housing 10 and the second housing 20. In this embodiment, by providing a cover plate, a detachable adapter plate, and a detachable output adapter component, when the output adapter component malfunctions, only the cover plate needs to be removed to replace the faulty component. This avoids the need to disassemble the first and second housings when the output adapter component malfunctions, which could lead to the failure of the waterproof sealing strip and improve the overall waterproof performance of the product.

The lamp body end also has a lighting source start button 104, a first lighting source brightness adjustment button 102, and a second lighting source brightness adjustment button 103. The lighting source start button 104 is used to start the lamp body for illumination. The first lighting source brightness adjustment button 102 and the second lighting source brightness adjustment button 103 are used to adjust the brightness of the lighting source. The brightness set by the second lighting source brightness adjustment button 103 is greater than the brightness set by the first lighting source brightness adjustment button 102. By providing the first lighting source brightness adjustment button 102 and the second lighting source brightness adjustment button 103, users can select the light brightness according to their needs.

[0064] The lamp body is symmetrically provided with a first limiting hole and a second limiting hole on its end side. The charging device is provided with a first limiting post and a second limiting post. The first limiting hole is used to mate with the first limiting post, and the second limiting hole is used to mate with the second limiting post.
