DETAILED DESCRIPTION

[0015] In order to explain the technical content, achieved objectives and effects of this application in detail, the following is an explanation in conjunction with the implementation methods and the accompanying drawings.

[0016] Please refer to Figures 1 to 4, a solar street light includes a first lamp body 1, a second lamp body 2, a first connecting member 3 and a connecting rod 4, the first connecting member 3 is connected to the first lamp body 1, one end of the connecting rod 4 is connected to the second lamp body 2, and the first connecting member 3 is rotatably mounted on the connecting rod 4; wherein, the connecting rod 4 is provided with at least one spiral protrusion 41 along its length extension direction, and the first connecting member 3 is provided with a groove 31 that cooperates with at least one spiral protrusion 41.

[0017] The structural principle of the present application is briefly described as follows: the first lamp body 1 of the solar street lamp provided in the present application is connected to the first connecting member 3, and the second lamp body 2 is connected to the connecting rod 4, wherein the first connecting member 3 can rotate on the connecting rod 4, and under the action of the spiral protrusion 41 and the groove 31, the first connecting member 3 will move along the length extension direction of the connecting rod 4 during the rotation process. Under the action of the first connecting member 3, when the first lamp body 1 and the second lamp body 2 rotate relative to each other, the first lamp body 1 can spirally rotate with the connecting rod 4 as the axis, that is, the first lamp body 1 can produce relative rotation with the second lamp body 2, and the first lamp body 1 can approach or move away from the second lamp body 2 along the connecting rod 4 when rotating.

[0018] In actual application, the operator can adapt the first connecting member 3, the connecting rod 4 and the spiral protrusion 41 on the connecting rod 4 so that the solar street light can achieve the following effects.

[0019] The first lamp body 1 can be spirally rotated with the connecting shaft as the axis and moved to the end of the connecting rod 4 close to the second lamp body 2. The central axis of the first lamp body 1 and the central axis of the second lamp body 2 can just coincide with each other. Please refer to the state diagram shown in Figure 1. The first lamp body 1 and the second lamp body 2 are horizontally connected. The solar street light is in the expanded state. Photovoltaic panels are provided on the top of the first lamp body 1 and the top of the second lamp body 2. The solar street light is in the expanded state. The area of ​​the photovoltaic panels is large, so the solar street light has a higher photovoltaic power generation power.

[0020] The first lamp body 1 can also be spirally rotated with the connecting rod 4 as the axis and moved to the end of the connecting rod 4 away from the second lamp body 2. The projection of the first lamp body 1 in the vertical direction and the projection of the second lamp body 2 in the vertical direction can just overlap. Please refer to the state diagram shown in Figure 4. The first lamp body 1 is retracted to the top of the second lamp body 2 (in other preferred embodiments of the present application, the first lamp body 1 can also be retracted to the bottom of the second lamp body 2). The solar street light is in a folded state. In this state, the structural integration of the solar street light is high and the projection area in the vertical direction is reduced. The operator can easily pack and transport the solar street light. In addition, in this state, there is a certain distance between the first lamp body 1 and the second lamp body 2. The raised component structure at the bottom of the first lamp body 1 (for example: the light-emitting module provided at the bottom of the first lamp body 1) can be accommodated between the first lamp body 1 and the second lamp body 2. During transportation, the operator can place buffer foam between the first lamp body 1 and the second lamp body 2, thereby improving the transportation safety of the solar street light.

[0021] From the above description, it can be seen that when the solar street light provided by the present application is packaged and transported, the operator can control the first lamp body 1 to rotate spirally along the connecting rod 4 so that the solar street light is in a folded state. At this time, the structural integration of the solar street light is improved and the overall volume is reduced, which can reduce the transportation cost of the solar street light; during installation and use, the operator can easily and quickly unfold the solar street light by controlling the first lamp body 1 to rotate spirally along the connecting rod 4. The solar street light generates electricity simultaneously through the photovoltaic panel on the top of the first lamp body 1 and the photovoltaic panel on the top of the second lamp body 2. The photovoltaic power generation power of the solar street light is high.

[0022] Furthermore, a limiting nut 5 is included, and the limiting nut 5 is provided at the other end of the connecting rod 4.

[0023] As can be seen from the above description, by providing the limit nut 5, the first connecting member 3 can be limited from spirally rotating along the connecting rod 4 within the range of movement, so as to prevent the first connecting member 3 from moving too far and falling off the connecting rod 4.

[0024] Furthermore, the other end of the connecting rod 4 is further provided with a first threaded portion 42 , and the limiting nut 5 is threadedly connected to the first threaded portion 42 .

[0025] As can be seen from the above description, the limiting nut 5 and the connecting rod 4 are threadedly connected, which can facilitate the operator to assemble and disassemble the limiting nut 5 and the connecting rod 4.

[0026] Of course, in some preferred embodiments of the present application, the limiting nut 5 and the connecting rod 4 can also be formed in one piece.

[0027] Furthermore, it includes a second connecting member 6 , which is connected to the second lamp body 2 , and one end of the connecting rod 4 is connected to the second connecting member 6 .

[0028] It can be seen from the above description that the second lamp body 2 is connected to the connecting rod 4 via the second connecting member 6 .

[0029] Furthermore, one end of the connecting rod 4 is further provided with a second threaded portion 43 , and the second connecting member 6 is threadedly connected to the second threaded portion 43 .

[0030] As can be seen from the above description, the second connecting member 6 is threadedly connected to the connecting rod 4, which can facilitate the operator to assemble and disassemble the second connecting member 6 and the connecting rod 4.

[0031] Furthermore, it also includes a limiting shaft 7, one end of which is rotatably connected to the second lamp body 2, and the other end of which is detachably connected to the first lamp body 1.

[0032] From the above description, it can be seen that the limit shaft 7 can limit the rotation of the first lamp body 1. When it is necessary to change the folding state or the unfolding state of the solar street lamp, the operator can remove one end of the limit shaft 7 from the first lamp body 1 to release the restriction of the limit shaft 7 on the first lamp body 1, so that the first lamp body 1 rotates spirally along the connecting rod 4; when it is necessary to fix the folding state or the unfolding state of the solar street lamp, the operator can connect one end of the limit shaft 7 to the first lamp body 1, so as to limit the relative rotation between the first lamp body 1 and the second lamp body 2, so as to avoid the relative rotation of the first lamp body 1 and the second lamp body 2 during use or transportation, thereby causing safety accidents or damage to the solar street light.

[0033] Furthermore, it also includes a hand screw 8, a first screw hole 71 is provided on the limiting shaft 7, and a second screw hole 11 is provided on the first lamp body 1 to match the first screw hole 71, and the hand screw 8 is sequentially passed through the first screw hole 71 and the second screw hole 11.

[0034] As can be seen from the above description, the hand screw 8 facilitates the operator to disassemble or install the limiting rotating shaft 7 and the first lamp body 1 .

[0035] Furthermore, the limiting shaft 7 is provided with at least two first screw holes 71 spaced apart along its extending direction.

[0036] It can be seen from the above description that in some preferred embodiments of the present application, the distances between the second screw hole 11 and the connection between the limiting shaft 7 and the second lamp body 2 of the solar street light are not equal in the unfolded state and in the folded state, so at least two first screw holes 71 are opened so that the limiting shaft 7 can limit the rotation of the first lamp body 1 in different states of the solar street light.

[0037] Furthermore, it also includes a shaft screw 9. The limiting shaft 7 is provided with a first shaft hole 72, and the second lamp body 2 is provided with a second shaft hole 21. The shaft screw 9 is sequentially passed through the first shaft hole 72 and the second shaft hole 21.

[0038] It can be seen from the above description that the limiting shaft 7 can rotate with the shaft screw 9 as the axis.

[0039] Furthermore, it includes two position-limiting rotating shafts 7 arranged in pairs, and the two position-limiting rotating shafts 7 arranged in pairs are respectively arranged on two opposite sides of the solar street light.

[0040] It can be seen from the above description that the two limiting rotation shafts 7 arranged in pairs have a more stable and firm effect in limiting the rotation of the first lamp body 1 .

[0041] Example 1

[0042] 1 to 4 , in a first embodiment of the present application, a solar street light includes a first lamp body 1 , a second lamp body 2 , a first connecting member 3 , a second connecting member 6 , a connecting rod 4 and a pair of limiting rotating shafts 7 .

[0043] The first lamp body 1 includes a light-emitting module, a first photovoltaic panel, and a first bracket. The light-emitting module is arranged at the bottom of the bracket, the photovoltaic panel is arranged at the top of the bracket, and the first connecting member 3 is arranged at one side of the first bracket.

[0044] The second lamp body 2 includes a recliner, a second photovoltaic panel, and a second bracket. The second photovoltaic panel is arranged on the top of the second bracket. A battery cavity is provided at the bottom of the second bracket. The second bracket is provided with a second connecting piece 6 and a recliner on two opposite sides. The solar street light is connected to the street light pole through the recliner, and the angle of the solar street light is adjusted.

[0045] One end of the connecting rod 4 is connected to the top of the second connecting member 6. As shown in FIG3 , the connecting rod 4 is provided with a spiral protrusion 41 along its length. The first connecting member 3 is rotatably mounted on the connecting rod 4 and is provided with a groove 31 that cooperates with the spiral protrusion 41. Therefore, the first connecting member 3 can drive the first lamp body 1 to rotate helically along the connecting rod 4. That is, the first lamp body 1 can approach or move away from the second lamp body 2 along the axial direction of the connecting rod 4 during the rotation process.

[0046] In order to limit the spiral rotation and movement of the first connecting member 3 on the connecting rod 4, a limit nut 5 is provided at the other end of the connecting rod 4 to prevent the first connecting member 3 from moving too far and falling off the connecting rod 4;

[0047] In this embodiment, a first threaded portion 42 and a second threaded portion 43 are respectively provided at both ends of the connecting rod 4. The first threaded portion 42 is threadedly connected to the limit nut 5, and the second threaded portion 43 is threadedly connected to the second connecting member 6. The operator can more easily assemble and fix the various components of the solar street light, thereby saving the production cost of the solar street light.

[0048] The pair of limiting rotating shafts 7 are respectively arranged on the other opposite sides of the second bracket, and one end of the limiting rotating shaft 7 is rotatably connected to the second bracket, and the other end of the limiting rotating shaft 7 is detachably connected to the first bracket.

[0049] In this embodiment, the solar street lamp further includes a shaft screw 9. A first shaft hole 72 is formed on the limit shaft 7, and a second shaft hole 21 is formed on the second lamp body 2. The shaft screw 9 is sequentially inserted into the first shaft hole 72 and the second shaft hole 21.

[0050] In order to further improve the efficiency of the operator in folding or unfolding the solar street light, in this embodiment, the solar street light also includes a hand screw 8, and a first screw hole 71 is provided on the limiting shaft 7, and a second screw hole 11 is provided on the first lamp body 1 to match the first screw hole 71. The hand screw 8 is sequentially passed through the first screw hole 71 and the second screw hole 11. The operator can use the hand screw 8 to more quickly disassemble or fix the other end of the limiting shaft 7 from the first bracket.

[0051] In actual use of the solar street light of this embodiment, the first connecting member 3 can rotate on the connecting rod 4, and under the action of the spiral protrusion 41 and the groove 31, the first connecting member 3 moves along the length extension direction of the connecting rod 4 during the rotation process. Under the action of the first connecting member 3, when the first lamp body 1 and the second lamp body 2 rotate relative to each other, the first lamp body 1 can spirally rotate with the connecting rod 4 as the axis;

[0052] As shown in Figure 1, when the solar street light needs to be packaged and transported, the operator can first loosen the hand screw 8 to disassemble the limit shaft 7 and the first lamp body 1, contact the limit shaft 7 to limit the rotation of the first lamp body 1, and then rotate the first lamp body 1. Since the connecting rod 4 is provided with a spiral protrusion 41, and the first connecting member 3 is provided with a groove 31 that matches the spiral protrusion, when the first lamp body 1 rotates, the first connecting member 3 will spirally rise around the connecting rod 4 until the first connecting member 3 conflicts with the limit nut 5; at this time, the first lamp body 1 is retracted above the second lamp body 2, and the operator can rotate the limit shaft 7 to the side of the first lamp body 1, and fix the limit shaft 7 to the first lamp body 1 by hand screwing the screw 8; at this time, the overall volume of the solar street light is reduced, which is convenient for packaging and transportation, and can reduce transportation costs

[0053] As shown in Figure 4, when the solar street light is installed and used on site, the operator can first loosen the hand screw 8 and then rotate the first lamp body 1. When the first lamp body 1 rotates, the first connecting member 3 will spiral down around the connecting rod 4 until the first connecting member 3 conflicts with the second connecting member 6; at this time, the first lamp body 1 and the second lamp body 2 are horizontally connected, and the operator can rotate the limit shaft 7 to the side of the first lamp body 1 and fix the limit shaft 7 to the first lamp body 1 by the hand screw 8. The first photovoltaic panel on the top of the first lamp body 1 and the second photovoltaic panel on the top of the second lamp body 2 generate electricity together to increase the photovoltaic power generation area and improve the photovoltaic power generation power.

[0054] To sum up, the solar street light provided in the present application can facilitate operators to pack and transport the solar street light while ensuring its photovoltaic panel area. The solar street light not only has high photovoltaic power generation power, but also has low transportation cost. In addition, it obtains a good fixing effect through the limiting shaft 7 in the folded state and the unfolded state, which can ensure the safety of the solar street light during use. In addition, the installation, unfolding and folding operations of the solar street light are simple, which can improve the packaging efficiency and installation efficiency of the operator.
