[0002] As the global demand for renewable energy continues to increase, solar energy, as a clean and renewable energy source, has attracted widespread attention.

[0003] Solar lights are lamps that convert solar panels into electrical energy. During the day, even on cloudy days, this solar generator can collect and store solar energy. As a safe and environmentally friendly new electric light, solar lights are becoming more and more popular. The working principle of solar lights is simple. They use solar panels made of the principle of photovoltaic effect. During the day, the solar panels receive solar radiation and convert it into electrical energy output. After the charge and discharge controller detects that the voltage is lower than the set value, it will start to operate, and the battery will discharge to the lamp body to start lighting.

[0004] In traditional solar lights, the solar panel is integrated with the lamp body, facing opposite sides respectively. It is usually fixed to the wall or lamp pole by using a clamp or other structure. After installation, the solar panel faces upward and the lamp body faces downward. The solar panel can convert the collected solar energy into electrical energy to power the lamp body. However, since the installation object of the solar lamp is not always perpendicular to the horizontal plane, it is difficult for the solar lamp to take into account the orientation of the light-receiving surface and the light-emitting surface, and the applicable scenarios are limited.

[0034] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0035] See also Figures 1 to 7The embodiment of the present application provides a foldable angle-adjustable solar lamp, which mainly includes a lamp body 10, a photovoltaic module 20, a mounting frame 30 and a supporting assembly 40. The lamp body 10 is electrically connected to the photovoltaic module 20. The lamp body 10 has a light-emitting surface facing away from the photovoltaic module 20. The photovoltaic module 20 has a light-receiving surface facing away from the lamp body 10. The photovoltaic module 20 can use the light-receiving surface to receive sunlight, thereby converting it into electrical energy and providing it to the lamp body 10. The mounting frame 30 is used to connect with the photovoltaic module 20 to fix the solar lamp to the installation object, such as a facade, a column, etc.

[0036] The first end of the lamp body 10 is rotatably connected to the photovoltaic assembly 20, the second end of the lamp body 10 is rotatably connected to the mounting frame 30, and the lamp body 10 can be maintained at at least two different tilt angles relative to the mounting frame 30, and the light emitting surface of the lamp body 10 and the light receiving surface of the photovoltaic assembly 20 are arranged opposite to each other. The two ends of the support assembly 40 are respectively connected to the lamp body 10 and the photovoltaic assembly 20, and the length of the support assembly 40 is adjustable, so that the lamp body 10 can be selectively supported at at least two tilt angles.

[0037] Through the above arrangement, on the one hand, the lamp body 10 can rotate relative to the mounting frame 30, so that the lamp body 10 can be maintained at at least two different inclination angles relative to the mounting frame 30, and the lamp body 10 can be set at a corresponding inclination angle according to the inclination requirements of the light-emitting surface to ensure the light-emitting direction and light-emitting range; on the other hand, the two ends of the support assembly 40 are respectively supported on the inner surfaces of the lamp body 10 and the photovoltaic assembly 20, so that after the support assembly 40 is installed, the lamp body 10, the photovoltaic assembly 20, and the support assembly 40 form a stable triangle, and by adjusting the working length of the support assembly 40, the photovoltaic assembly 20 can be further supported at different inclination angles relative to the lamp body 10, so that the inclination angle of the photovoltaic assembly 20 relative to the lamp body 10 can be adjusted, thereby adaptively compensating for the variable of the orientation of the photovoltaic assembly 20 after the angle of the lamp body 10 is adjusted, so that the light-receiving surface of the photovoltaic assembly 20 can be adjusted to face the sunlight. That is, the inclination angle of the lamp body 10 relative to the mounting frame 30 is adjustable, and the inclination angle of the photovoltaic assembly 20 relative to the lamp body 10 is also adjustable, which can ensure the orientation of both the light emitting surface and the light receiving surface.

[0038] For example, when the installation surface of the installation object is slightly inclined, by installing the mounting bracket 30 on the mounting surface and adjusting the inclination angle of the lamp body 10 relative to the mounting bracket 30, the light-emitting surface of the lamp body 10 maintains a predetermined direction and emits light; then, by adjusting the length of the supporting assembly 40, the inclination angle of the photovoltaic assembly 20 relative to the lamp body 10 is changed, so that the light-receiving surface of the photovoltaic assembly 20 faces the sun at a predetermined angle, thereby realizing simultaneous adjustment of the light-emitting surface and the light-receiving surface, and meeting the light-receiving and light-emitting requirements at the same time.

[0039] Exemplarily, the light-receiving surface of the photovoltaic module 20 faces the sun, and the elevation angle is within the range of 15° to 20° (including the endpoints), which takes into account the charging effect and can prevent rain, dust, etc. from gathering on the light-receiving surface of the photovoltaic module 20 and affecting the light energy conversion effect. In addition, since the photovoltaic module 20 can be tilted to block the upper side of the lamp body 10, it just blocks the strong sunlight, and a triangular heat buffer area is formed between the photovoltaic module 20 and the lamp body 10. Most of the heat generated by the photovoltaic module 20 under light can be dissipated from the heat buffer area to the air, avoiding the problem of excessive temperature of the lamp body 10 caused by the direct adhesion of the photovoltaic module 20 to the lamp body 10 in the traditional flat solar lamp, which affects the working performance of the electrical components inside the lamp body 10.

[0040] Figures 1 to 3 FIG. 2 shows one of the usage states of the solar lamp of this embodiment. Figures 1 to 4 As shown, in one embodiment, the two ends of the support assembly 40 are respectively connected to the middle part of the photovoltaic assembly 20 and the lamp body 10. Exemplarily, the support assembly 40 includes a first connecting arm 41 and a second connecting arm 42 that are slidably connected, and a first adjusting member 43; the first connecting arm 41 and the second connecting arm 42 are rotatably connected to the lamp body 10 and the photovoltaic assembly 20, respectively, and the two are slidably connected to each other, and the first adjusting member 43 is used to relatively fix the first connecting arm 41 and the second connecting arm 42, so that the support assembly 40 can be selectively locked in at least two different working lengths.

[0041] In one embodiment, in combination Figures 3-4 As shown, the second connecting arm 42 is slidably arranged in the first connecting arm 41, and the first adjusting member 43 is a screw, such as a quick-release screw. The first connecting arm 41 is provided with a long strip-shaped guide hole 410 extending along its length direction, and the second connecting arm 42 is provided with a fixing hole 420, such as a threaded hole. The first adjusting member 43 is passed through the guide hole 410 and fixed in the fixing hole 420. The first adjusting member 43 can press the first connecting arm 41 against the second connecting arm 42, and the first connecting arm 41 and the second connecting arm 42 can no longer move, thereby realizing the relative fixation of the first connecting arm 41 and the second connecting arm 42; when it is necessary to adjust the working length of the support assembly 40, it is only necessary to loosen the first adjusting member 43, the first adjusting member 43 no longer presses the first connecting arm 41, and the first adjusting member 43 can move in the guide hole 410. When the length of the support assembly 40 is adjusted to a suitable size, the first adjusting member 43 can be tightened.

[0042] It can be understood that the way in which the first adjusting member 43 adjusts the combined length of the first connecting arm 41 and the second connecting arm 42 is not limited to this, and other similar adjustment methods may also be used. For example, in one embodiment, the guide hole 410 has a plurality of spaced limiting portions 411, and each of the limiting portions 411 is spaced along the length direction of the guide hole 410 to form a step groove connected to the guide hole 410. When the head of the first adjusting member 43 is located in one of the step grooves, the first adjusting member 43 can no longer slide along the guide hole 410, and the relative fixation of the first connecting arm 41 and the second connecting arm 42 can be achieved. This method does not need to use the friction force generated by the compression to limit the relative movement of the first connecting arm 41 and the second connecting arm 42, and is more convenient to achieve.

[0043] In one embodiment, a recessed portion 100 is provided on the surface of the lamp body 10 facing the support assembly 40, and the first connecting arm 41 and the second connecting arm 42 can be accommodated in the recessed portion 100. In some scenarios, when there is no need to set an inclination angle between the lamp body 10 and the photovoltaic assembly 20, such as during storage or transportation, or when the installation scenario requires that the light-emitting surface of the lamp body 10 and the light-entering surface of the photovoltaic assembly 20 be set to be opposite, the support assembly 40 can be folded and accommodated in the recessed portion 100. For example, the first adjustment member 43 can be removed so that the first connecting arm 41 and the second connecting arm 42 are no longer connected, and then the first connecting arm 41 and the second connecting arm 42 are folded and installed in the recessed portion 100, thereby achieving a state in which the photovoltaic assembly 20 covers the surface of the lamp body 10 (such as Figure 5 Then, the fastener T (as shown) can be used to Figure 1 ), fix the lamp body 10 to the photovoltaic component 20.

[0044] In one embodiment, the solar lamp further comprises a second adjusting member 50. The mounting frame 30 is provided with at least two limiting holes 31 spaced apart along its width direction, and the second adjusting member 50 can be selectively inserted into different limiting holes 31 to support the lamp body 10 at different angles.

[0045] like Figure 6 , 7 As shown, a second adjusting member 50 is provided through a different Figures 1 to 4 In this embodiment, there are three limiting holes 31, which are the limiting holes 31 of level 1 to level 3 from bottom to top. Figures 1 to 4 In the state, the second adjusting member 50 is inserted into the lowermost limiting hole 31 (such as Figure 2 The limit hole 31 corresponding to the "1" gear shown in the figure, Figure 6 , 7 In the state of Figure 7 The limit hole 31) corresponding to the "3" position shown in the figure is Figures 1 to 4Compared with the state of the lamp body 10 facing downward relative to the mounting frame 30 (such as Figure 1 , 6 The lamp body 10 swings relative to the horizontal direction (as shown in the direction opposite to the Z axis). Figure 1 , 6 and in order to maintain the elevation angle of the photovoltaic assembly 20 substantially unchanged, the working length of the support assembly 40 is correspondingly increased, specifically adjusted to the maximum working length.

[0046] In one embodiment, the first adjusting member 43 has a plurality of first locking gears, such as 1 to 3 gears, and the second adjusting member 50 has a plurality of second locking gears, such as 1 to 3 gears, and the first locking gears 1 to 3 gears correspond one to one with the second locking gears 1 to 3 gears, so that when the first adjusting member 43 is in one of the first locking gears, such as the "1" gear, and the second adjusting member 50 is in the corresponding second locking gear, such as the "1" gear, the photovoltaic assembly 20 can be maintained at a preset angle or a preset angle range. For example, when the first adjusting member 43 is in the "1" gear and the second adjusting member 50 is in the "1" gear, the first adjusting member 43 is in the "2" gear and the second adjusting member 50 is in the "2" gear, and the first adjusting member 43 is in the "3" gear and the second adjusting member 50 is in the "3" gear, the photovoltaic assembly 20 in the three states can maintain the same angle.

[0047] In this embodiment, the support assembly 40 is provided with first marks corresponding to multiple first locking positions, 1 to 3, and the mounting frame 30 is provided with second marks corresponding to multiple second locking positions, 1 to 3. Each first mark is the same as or corresponds to the corresponding second mark, such as gears 1 to 3 on the support assembly 40 correspond to gears I to III on the mounting frame 30 respectively.

[0048] Exemplarily, the first mark may be disposed on the first connecting arm 41 , next to the guide hole 410 .

[0049] In one embodiment, the mounting frame 30 includes a connecting arm 32 and a mounting portion 33 arranged at an angle, the connecting arm 32 is connected to the lamp body 10, and the mounting portion 33 is used to cooperate with the installation object to achieve installation. The mounting portion 33 may also include a threading portion 331 provided on opposite sides of the mounting portion 33, and the threading portion 331 can be used for the wire harness to pass through, so as to tie the mounting portion 33 to the installation object.

[0050] During installation, the mounting portion 33 can be first placed close to the object to be installed, and then a wire harness can be passed through each threading portion 331 to tie the mounting portion 33 to the object to be installed. There can be multiple groups of threading portions 331, which are arranged at intervals along the length direction of the mounting portion 33, and each group of threading portions 331 can be threaded with a wire harness to tie the mounting portion 33.

[0051] like Figure 2In one embodiment, the outer surface of the mounting portion 33 is a curved recessed mounting surface 330, and the mounting surface 330 of the mounting portion 33 can fit with the outer circumferential surface of a cylindrical mounting object.

[0052] By setting the mounting surface 330 as a curved surface, the mounting frame 30 can be suitable for a curved mounting object, such as a lamp pole or a curved column.

[0053] Furthermore, at least one threading portion 331 can be configured as a notch. Since the threading portion 331 is notch-shaped, the wire harness can be conveniently passed through the threading portion 331, making the assembly and disassembly work faster and more convenient.

[0054] In addition, the mounting portion 33 also includes a hanging hole 332 that runs through its thickness direction. The hanging hole 332 includes a connected penetration portion and a clamping portion. The size of the clamping portion along the width direction of the mounting portion 33 is smaller than the penetration portion, so that the screw can be clamped in the clamping portion after passing through the penetration portion.

[0055] Through the above arrangement, the mounting portion 33 can be fixed to the mounting object in a variety of fixing methods, which broadens the installation scenarios of the solar lamp, makes the installation method more flexible, and improves practicality.

[0056] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
