[0048] The lamp body fixing structure on the first housing includes: receiving grooves at both ends of the lamp body, damping columns dividing the receiving grooves into a first opening and a second opening, and mounting accessories for mounting the lamp body on the mounting surface; the length direction of the damping column is the same as the length direction of the lamp body, and the upper surface of the damping column is the same plane as the arc-shaped surface; the mounting accessories form a closed loop connection through connection relationships with the receiving grooves at one end of the lamp body and with the receiving grooves at the other end of the lamp body, and the lamp body is mounted on the mounting surface through the mounting accessories.

[0049] The lighting source and the circuit board are fixed in the lamp body, and the light emitted by the lighting source is emitted through the second housing for illumination.

[0050] The side plate is provided with a charging interface that connects to the circuit board. The lamp body, as a device being charged, is charged by connecting to the charging device through the charging interface.

[0051] The following combination Figures 1-9 This article provides a detailed introduction to solar-powered charging lights.

[0052] Please see Figure 1 , Figure 1This is a front view of the first suspended state of the solar charging lamp provided in this application. The solar charging lamp includes: a first housing 10, a second housing 20, a lighting source, a charging interface, a circuit board, and a lamp body fixing structure 30 disposed on the first housing 10; the first housing 10 and the second housing 20 are fitted together to form the lamp body. In specific implementation, the first housing 10 and the second housing 20 can be fitted together to form the lamp body in various ways. One way is that the first housing 10 and the second housing 20 are fitted together to form the lamp body by snap-fitting. For example, the first housing 10 is provided with multiple positioning holes, and the preset positions of the positioning holes are provided with positioning grooves. The second housing 20 is provided with positioning posts that match the multiple positioning holes, and the preset positions of the positioning posts are provided with positioning protrusions, and the positioning protrusions are elastically connected to the positioning posts.

[0053] The lamp body fixing structure 30 is used to fix the lamp body and can adjust the illumination angle of the light source, so that the solar charging lamp can illuminate different directions according to different usage needs. At the same time, it also facilitates the portability of the solar charging lamp. The lighting source and the circuit board are fixed in the lamp body, and the light emitted by the lighting source is emitted through the second housing 20 for illumination. The second housing 20 is a transparent housing to facilitate light transmission.

[0056] The side plate 104 is provided with a charging interface 1041 connected to the circuit board. The lamp body is the device being charged. The lamp body is matched and installed with the charging device 401, and is connected to the charging port of the charging device 401 through the charging interface 1041 to charge the lamp body.

[0057] Please see Figure 5 , Figure 5This is a schematic diagram of the receiving groove of the solar charging lamp provided in this application. The lamp body fixing structure 30 on the first housing 10 includes: receiving grooves 301 provided at both ends of the lamp body, damping columns 302 dividing the receiving grooves into a first opening and a second opening, and mounting accessories 303 for mounting the lamp body to the mounting surface. The mounting accessories 303 can be made of flexible material. The first opening and the second opening are symmetrically arranged with the damping column as the axis of symmetry. The length direction of the damping column 302 is the same as the length direction of the lamp body, and the upper surface of the damping column 302 is on the same plane as the arc-shaped surface. The mounting accessories 303 form a closed loop connection through connection relationships with the receiving grooves 301 provided at one end of the lamp body and with the receiving grooves 301 provided at the other end of the lamp body. The lamp body is mounted to the mounting surface through the mounting accessories 303.

[0058] In this embodiment, the receiving grooves 301 provided at both ends of the lamp body may include: a first receiving groove 3011 provided at one end of the lamp body, located at the connection between the third lamp plate 103 and the first lamp plate 101, and a second receiving groove 3012 provided at the connection between the third lamp plate 103 and the second lamp plate 102; a third receiving groove 3013 provided at the other end of the lamp body, located at the connection between the third lamp plate 103 and the first lamp plate 101, and a second receiving groove 3012 provided at the connection between the third lamp plate 103 and the second lamp plate 102; and a third receiving groove 3013 provided at the connection between the third lamp plate 103 and the first lamp plate 101, and a second receiving groove 3012 provided at the connection between the third lamp plate 103 and the second lamp plate 102.

[0059] In this embodiment of the application, the first housing 10 is provided with four receiving slots, and two adjacent receiving slots are symmetrically arranged. Each receiving slot has two openings, namely a first opening and a second opening.

[0060] It is understood that the number of accommodating slots can be two or other numbers. When there are two, they can be set at both ends of the lamp body and located on top of the third lamp plate, or they can be staggered on the first lamp plate and the second lamp plate with the length bisector of the third lamp plate as the axis of symmetry. In this embodiment, four slots are mainly used as an example, but it is not limited to four. The specific number can be determined according to the structural characteristics of the lamp body, such as the length, weight, and usage scenario of the lamp body.

[0061] Please see Figure 6 , Figure 6 This is a schematic diagram of the first and second openings of the receiving groove of the solar charging lamp provided in this application. The mounting accessory 303 forms a closed-loop connection through its connection relationship with the receiving groove 301 at one end of the lamp body and its connection relationship with the receiving groove 301 at the other end of the lamp body.

[0062] For specific implementation details, please refer to [link / reference]. Figure 3The lamp body is mounted on the mounting surface via the mounting accessory 303, including: the mounting accessory 303 forming a first mounting accessory segment 3031 between the first receiving groove 3011 and the second receiving groove 3012. Specifically, the first mounting accessory segment 3031 is formed by one end of the mounting accessory 303 entering from the first opening 3011-1 of the first receiving groove 3011, exiting from the second opening 3011-2 of the first receiving groove 3011, entering the second opening of the second receiving groove 3012 along the width direction of the lamp body, and exiting from the first opening of the second receiving groove 3012. The first mounting accessory segment 3031 can be formed between the first receiving groove 3011 and the second receiving groove 3012 in the above manner. The mounting accessory 303 forms a second mounting accessory segment 3032 between the third receiving groove 3013 and the fourth receiving groove 3014. Specifically, the mounting accessory 303 extends out of the second opening of the third receiving groove 3013, enters the second opening of the fourth receiving groove 3014 along the width direction of the lamp body, and extends out of the first opening of the fourth receiving groove 3014. The second mounting accessory segment 3032 can be formed between the third receiving groove 3013 and the fourth receiving groove 3014 in the above manner. Both the first mounting accessory segment 3031 and the second mounting accessory segment 3032 are fitted to the first housing 10; the mounting accessory 303 is located outside the lamp body and is installed in conjunction with the mounting accessory 303, so that the area of ​​the first contact surface or the second contact surface near the arc-shaped convex surface is fitted to the mounting surface. The force exerted by the mounting accessory 303 near the mounting surface on the damping column 302 is less than the force exerted by the mounting accessory 303 away from the mounting surface on the damping column 302, and the illumination angle of the lamp body in the length direction is adjusted.

[0063] In practice, the lighting angle of the lamp body can be adjusted according to requirements; see details below. Figure 1 and Figure 2 , Figure 1 This is a front view of the solar charging lamp in its first suspended state provided in this application. Figure 2 This is a side view of the solar-powered charging lamp provided in this application in its first suspended state, where the first suspended state is the illumination angle of the lamp body along its length. Figure 2 As can be seen, depending on the adjustment angle of the lamp body, specifically, the area near the curved convex surface of the first or second contact surface may be in contact with the mounting surface, or the position where the first or second lamp plate and the third lamp plate meet may be in contact with the mounting surface. With the cooperation of the damping column and mounting accessories, this can be achieved as follows: Figure 2 The illumination angle in the indicated direction.

[0064] Please see Figure 3 and Figure 4 , Figure 3 This is a front view of the second suspended state of the solar charging lamp provided in this application. Figure 4 This is a side view of the second suspended state of the solar-powered charging lamp provided in this application. The second suspended state also represents the illumination angle of the lamp body along its length, with the light shining vertically downwards. Figure 4 As can be seen, depending on the adjustment angle of the lamp body, the first or second contact surface may be in contact with the mounting surface, or the position where the first or second lamp plate is joined to the second housing may be in contact with the mounting surface. With the cooperation of the damping column and mounting accessories, the following can be achieved: Figure 4 The illumination angle in the indicated direction.

[0065] Of course, the contact area between the mounting accessories and the damping column, as well as the weight of the lamp body, will also affect the lighting angle. For example, if the contact area between the mounting accessories and the damping column is relatively large, the damping sensation between the mounting accessories and the damping column can be increased. In practice, protrusions can also be set on the mounting accessories, which can also increase the damping sensation between the mounting accessories and the damping column, making the lighting angle of the lamp body more stable.

[0066] The above describes how the lighting angle of the lamp body is adjusted in the length direction. The following describes how the lighting angle of the lamp body is adjusted in the height direction.

[0067] Please see Figure 7 , Figure 7This is a structural schematic diagram of the solar charging lamp with height-direction lighting provided in this application. In specific implementation, the lamp body is installed on the mounting surface through the mounting accessory 303, including: the mounting accessory 303 forming a first mounting accessory segment 3031 between the first receiving groove 3011 and the second receiving groove 3012. Specifically, the first mounting accessory segment 3031 is formed by one end of the mounting accessory 303 entering from the first opening 3011-1 of the first receiving groove 3011, exiting from the second opening 3011-2 of the first receiving groove 3011, entering the second opening of the second receiving groove 3012 along the width direction of the lamp body, and exiting from the first opening of the second receiving groove 3012. The first mounting accessory segment 3031 can be formed between the first receiving groove 3011 and the second receiving groove 3012 in the above manner. The mounting accessory 303 forms a second mounting accessory segment 3032 between the third receiving groove 3013 and the fourth receiving groove 3014. Specifically, the mounting accessory 303 extends out of the second opening of the third receiving groove 3013, enters the second opening of the fourth receiving groove 3014 along the width direction of the lamp body, and extends out of the first opening of the fourth receiving groove 3014. The second mounting accessory segment 3032 can be formed between the third receiving groove 3013 and the fourth receiving groove 3014 in the above manner.

[0068] In one implementation, the second mounting accessory segment 3032 is fitted to the first housing 10. In this case, the first mounting accessory segment 3031 is located outside the lamp body, and this location is at one end of the lamp body. Alternatively, in another implementation, the first mounting accessory segment 3031 is fitted to the first housing 10. In this case, the second mounting accessory segment 3032 is located outside the lamp body, and this location is at the other end of the lamp body. The mounting accessory 303 forms a third mounting accessory segment (not shown in the figure) between the second receiving groove 3012 and the fourth receiving groove 3014. Specifically, the third mounting accessory segment is formed by the mounting accessory 303 extending from the first opening of the second receiving groove 3012 along the length direction of the lamp body into the first opening of the third receiving groove 3013, and then exiting from the second opening of the third receiving groove 3013. The third mounting accessory segment can be formed between the second receiving groove 3012 and the fourth receiving groove 3014 in the above manner. The mounting accessory 303 forms a fourth mounting accessory segment 3034 between the first receiving groove 3011 and the third receiving groove 3013. Specifically, the fourth mounting accessory segment 3034 is formed by the mounting accessory 303 passing through the second opening of the third receiving groove 3013, entering the second opening of the fourth receiving groove 3014 along the width direction of the lamp body, and passing through the first opening of the fourth receiving groove 3014. The fourth mounting accessory segment 3034 can be formed between the first receiving groove 3011 and the third receiving groove 3013 in the above manner. Both the third mounting accessory segment and the fourth mounting accessory segment 3034 are fitted to the first housing 10, and the mounting accessory 303 is located at one end of the lamp body outside the lamp body. Specifically, it can be either the first mounting accessory segment 3031 or the second mounting accessory segment 3032. The mounting accessory 303 is installed in conjunction with the lamp body outside the lamp body, so that the lamp body is fitted to the mounting surface in a direction perpendicular to the ground, and the lighting angle of the lamp body is adjusted to the lighting angle in the height direction.

[0069] The above describes adjusting the lighting angle of the lamp body to the lighting angle in the height direction. The solar charging lamp provided in this application not only realizes the portable adjustment of the lighting angle of the lamp body by adjusting the fit or contact relationship between the lamp body and the mounting surface, and by the structural relationship between the damping column and the receiving groove, but also ensures the stability after the lighting angle is adjusted. That is, the needs of different lighting angles can be met through simple structural and fit relationships. Compared with the existing lighting angle adjustment scheme, the manufacturing and processing costs are lower, and it is more suitable for the use needs of remote and underdeveloped areas.

[0070] In this embodiment of the application, please refer to Figure 8 , Figure 8 This is a partially enlarged structural diagram of the receiving groove of the solar charging lamp provided in this application. The receiving groove 301 has a first groove surface 3015 and a second groove surface 3016 symmetrically positioned along the length of the lamp body, and a third groove surface 3017 connects the bottom of the first groove surface 3015 and the second groove surface 3016.

[0071] To facilitate the connection between the installation accessories and the receiving groove, the included angle formed by the connection of the first groove surface 3015 and the second groove surface 3016 with the third groove surface 3017 is an obtuse angle.

[0072] In this embodiment, the damping column 302 has a trapezoidal cross-section along the length of the lamp body. The lower base of the trapezoid is the outer surface of the damping column 302, and the outer surface is on the same plane as the surface of the third lamp plate 103 where the damping column 302 is located. The upper base of the trapezoid is parallel to the third groove surface 3017. It should be noted that, as one implementation, the damping column 302 can also be detachably disposed in the receiving groove 301. Specifically, a first groove and a second groove can be respectively provided on the inner wall of the receiving groove 301 connected to the damping column 302. One end of the damping column 302 is provided with a first engaging structure for engaging with the first groove, and the other end of the damping column is provided with a second engaging structure for engaging with the second groove. The first engaging structure and the second engaging structure are elastic fasteners. The damping post 302 has a third groove and a fourth groove at both ends. The first snap-fit ​​structure is accommodated in the third groove, and the second snap-fit ​​structure is accommodated in the fourth groove. The length of the first snap-fit ​​structure is greater than the depth of the third groove, and the length of the second snap-fit ​​structure is greater than the depth of the fourth groove. When the first groove engages with the first snap-fit ​​structure, the first snap-fit ​​structure first retracts inward and, after aligning with the first groove, extends into the first groove. When the second groove engages with the second snap-fit ​​structure, the second snap-fit ​​structure first retracts inward and, after aligning with the second groove, extends into the second groove, thereby installing the damping post 302 in the receiving groove 301. During disassembly, the first and second snap-fit ​​structures similarly retract inward, thereby removing the damping post 302 from the receiving groove 301. It should be noted that the retraction and extension of the first and second snap-fit ​​structures are achieved through a control telescopic button provided on the damping post 302.

[0073] In this embodiment, the receiving groove 301 can be located at both ends of the lamp body, in the middle of the lamp body, or at one-third of the lamp body. There is no limitation on this. Furthermore, the width of the mounting accessory 303 is less than or equal to the width of the receiving groove 301, so as to facilitate the mounting accessory to pass through the receiving groove.

[0074] In this embodiment of the application, the second housing 20 is also provided with an output port (not shown in the figure). The output port is connected to the circuit board through a wire. When the lamp body is used as a charging device, it charges the device to be charged through the output port.

[0075] Please see Figure 9 , Figure 9 This is a schematic diagram of the side panel structure of the solar charging lamp provided in this application. The side panel 104 is provided with a charging interface 1041 connected to the circuit board. Specifically, the charging interface 1041 can be a cylindrical pin, which is electrically connected to the charging module on the circuit board, and the charging module is electrically connected to the circuit board. The lamp body serves as the device being charged. The lamp body is matched and installed with the charging device 401, and is connected to the charging port of the charging device 401 through the charging interface 1041 to charge the lamp body. The side panel 104 is also provided with a lighting source start button 1042, a first lighting source brightness adjustment button 1043, and a second lighting source brightness adjustment button 1044. The lighting source start button 1042 is used to start the lamp body for lighting. The first lighting source brightness adjustment button 1043 and the second lighting source brightness adjustment button 1044 are used to adjust the brightness of the lighting source. The brightness set by the second lighting source brightness adjustment button 1044 is greater than the brightness set by the first lighting source brightness adjustment button 1043. By setting the first lighting source brightness adjustment button 1043 and the second lighting source brightness adjustment button 1044, users can select the light brightness according to their usage needs.

[0076] The side plate 104 is also symmetrically provided with a first limiting hole 1045 and a second limiting hole 1046, which can communicate with the receiving groove. The charging device 401 is provided with a first limiting post and a second limiting post. The first limiting hole 1045 is used to match and plug into the first limiting post, and the second limiting hole 1046 is used to match and plug into the second limiting post. When the charging interface 1041 is plugged into the charging port on the charging device, an electrical connection is achieved, and the lamp body is charged. With the cooperation of the first limiting hole and the first limiting post, and the cooperation of the second limiting hole and the second limiting post, the solar charging lamp can be more securely plugged in during the charging process, avoiding the occurrence of loose connection under the action of external force. It should be noted that the number of upper limit holes on the side plate mentioned above can also be set to one or other numbers, and is not limited to two. The specific number can be set according to actual needs. For example, a limit hole can also be set on the side plate. When the charging interface 1041 is connected to the charging port on the charging device, the limit hole is connected to the limit post on the charging device 401, which can also achieve the effect of more stable connection of the solar charging lamp during the charging process.

[0077] In this embodiment, the inner surface of the damping column 302 and / or the arc-shaped convex surface are provided with an anti-slip structure (not shown in the figure). This anti-slip structure contacts the mounting accessory 303 after the lamp body is installed on the mounting surface. The anti-slip structure is a continuous or discrete raised anti-slip strip and / or dot-like protrusions. Of course, this anti-slip structure can also be other structures that provide an anti-slip effect. By providing the anti-slip structure, the friction between the mounting accessory 303 and the damping column 302 can be increased, making the position of the lamp body more stable after adjusting the light illumination angle.

[0078] It should be noted that the lamp body is also equipped with a port for charging via the power grid. Through this port, the power interface provided by the power grid can be plugged in to charge the solar charging lamp. Alternatively, the charging interface can be used to charge the solar charging lamp with a charging device, thereby enabling the solar charging lamp to be charged with different power supply models, making the charging method more comprehensive and convenient.

[0079] The above is a general description of the solar-powered rechargeable lamp provided in this application. This solar-powered rechargeable lamp features a lamp body fixing structure, which includes mounting accessories for installing the lamp body onto the mounting surface. It also includes receiving slots at both ends of the lamp body and damping columns dividing these slots into a first opening and a second opening. The mounting accessories can form a closed-loop connection through connections to the receiving slots at one end and the other end of the lamp body. By mounting the lamp body onto the mounting surface using the mounting accessories, the illumination angle of the lamp body can be adjusted along its length and its height. Therefore, the solar-powered rechargeable lamp provided in this application can adjust the illumination angle of the light source, allowing it to illuminate different directions according to different usage needs. It also facilitates the portability of the solar-powered rechargeable lamp.

[0080] The solar-powered rechargeable lamp provided in this application not only achieves portable adjustment of the lamp's lighting angle by adjusting the fit or contact relationship between the lamp body and the mounting surface, and through the structural relationship between the damping column and the receiving groove, but also ensures the stability of the lighting angle after adjustment. That is, the needs of different lighting angles can be met through simple structural and fit relationships. At the same time, the above-mentioned angle adjustment method improves the utilization rate of light and avoids the situation where most of the light shines on the mounting surface instead of the work area. Compared with existing lighting angle adjustment solutions, it has lower manufacturing and processing costs and is more suitable for the needs of remote and underdeveloped areas.
