Description

Technical Field

[0001] The utility model relates to the field of solar lamps, in particular to a foldable solar panel structure and a street lamp. Background Art

[0002] Street lights are used for lighting and are indispensable public facilities for roads in towns and villages. Traditional street lights are connected to the mains, which not only consumes a lot of mains electricity, but also has a high cost for installing the mains. For some special areas, it is even impossible to introduce mains electricity. Therefore, solar street lights have appeared, which use solar panels to convert solar energy into electrical energy for storage. When night falls, the battery will power the lamp.

[0003] In the prior art, CN209084633U discloses a base of a solar panel module, which is hexagonal in shape and mainly consists of a base, a mounting frame and a solar panel. Figure 3 As shown, the mounting frame includes two split parts, and the two adjacent split parts are connected and fixed by a first buckle connection structure (first buckle slot, first buckle part); see Figure 6 As shown, the base includes two split parts, and the two adjacent split parts are connected by a second buckle connection structure (including a second buckle slot and a second bayonet member), that is, the adjacent split parts are fixedly connected by the buckle slot. This traditional structure has the following defects:

[0004] ① After the adjacent parts are fixedly connected by snap-fit ​​slots, the outline of the solar panel module has been fixed, so that the solar panel module will occupy a large volume during packaging and transportation, which will greatly increase the logistics cost, especially the international logistics cost;

[0005] ② Different lamp poles have different diameters and require different sizes of solar panel modules. Therefore, some lamp poles need hexagonal solar panel modules to cover them, while some lamp poles may need octagonal solar panel modules to match. In hexagonal and octagonal solar panel modules, the angles between two adjacent split parts are different. Therefore, the angle orientation requirements for the bayonet parts and the slots on the split parts are also different. This requires different molds for the split parts produced by solar panel module manufacturers to meet the assembly requirements of different numbers of sides. In other words, the split parts are not universal parts on solar panel modules with different numbers of sides, which will undoubtedly greatly increase the production costs of manufacturers.

[0006] ③. For structures that require mounting frames, the mounting frames are made of large areas of aluminum, which is very expensive.

[0007] Therefore, it is necessary to improve and optimize the existing solar panel structure. Utility Model Content

DETAILED DESCRIPTION

[0040] In order to make the purpose, technical solution and advantages of the utility model more clear, the embodiments of the utility model will be described in detail below with reference to the accompanying drawings. It should be noted that the embodiments and features in the embodiments described below can be combined with each other arbitrarily without conflict.

[0041] Many different implementations or examples are provided below to implement the structure of the present utility model.

[0042] See also Figure 1-Figure 21The first aspect of the utility model provides a foldable solar panel structure, including a plurality of solar panel units 1, wherein the solar panel units include a solar panel assembly 11, and end caps 12 arranged at the upper and lower ends of the solar panel assembly, and the left and right ends of the end caps 12 are provided with support ears 121, and two adjacent solar panel units 1 are connected by the support ears 121 in cooperation with the connecting shaft 2, wherein at least part of the connecting shaft 2 is a hinge shaft, and the hinge shaft can be a stud or a rivet; the two solar panel units 1 connected by the hinge shaft can be relatively folded or unfolded, and a plurality of solar panel units can be enclosed to form a polygon; at least part of the end caps 12 are provided with screw holes 122, and the screw holes 122 extend radially, and the screw holes 122 are through holes; during production, the demander can adjust the lamp pole diameter. The size of the solar panel structure is provided to the solar panel structure manufacturer. The manufacturer determines the number of solar panel units 1 required based on the diameter of the lamp pole and the width of each solar panel unit 1. For example, if six solar panel units are needed, the manufacturer can hinge the six solar panel units end to end (the hinge axis can use studs or rivets), and the first and sixth ones are not connected. They are provided to the purchaser with studs. After the purchaser encloses and fixes the solar panel structure on the lamp pole, the studs are used to connect and fix the ears 121 of the first and sixth solar panel units. The manufacturer can also divide the six solar panel units into two groups, each with three solar panel units that have been hinged in the factory. The two groups are finally assembled by the purchaser. When connecting the two groups, the purchaser can use studs for hinged connection, or use studs or other structures to lock them without hinges. Compared with traditional structures, when transportation is required, whether it is 6 or 3 hinged solar panel units, they can be unfolded. Fig.16 The straight shape shown can be used to group the unfolded multiple solar panel units into a group and stack them for packaging, so that the packaging box space can be fully utilized. More solar panel units can be packed in the packaging box of the same volume, which is conducive to greatly reducing transportation costs. For lamp poles of different diameters, it is only necessary to increase or decrease the solar panel units. Although increasing or decreasing the solar panel units changes the angle between the two adjacent solar panel units after assembly, it can be easily adjusted through hinges, so that each solar panel unit can be used as an independent component. This will greatly reduce the number of molds for manufacturers and greatly reduce their production costs. The number of solar panel units is ≥4, so that multiple solar panel units 3 can be enclosed in a variety of shapes. For details, see Figure 17-Figure 21As shown, the polygon is a regular polygon or a rectangle. For manufacturers, for solar panel structures with fewer sides, multiple solar panel units can be connected end to end and hinged (two of the solar panel units are left unconnected and left for connection at the construction site). For solar panel structures with more sides, multiple solar panel units can be divided into multiple groups, each group includes 2 or more solar panel units, and the solar panel units in each group are connected end to end and hinged (two of the solar panel units are left unconnected and left for connection at the construction site). For street lamp construction sites, solar panel construction workers only need to connect one or more groups prefabricated by the manufacturer on the lamp pole through a connecting shaft. Compared with the method of connecting and installing each solar panel unit on site at the construction site, the workload of construction workers is significantly reduced, labor intensity is reduced, and construction efficiency is improved. Therefore, the structure described in the utility model takes into account transportation, construction and cost, has a simple and ingenious structure, and has good market competitiveness.

[0043] See Figure 7-Figure 10 As shown, in some embodiments of the present invention, the ears 121 at the left and right ends of the end cover 12, wherein the left ear is higher than the right ear, or the left ear is lower than the right ear, that is, the ears 121 at the left and right ends of the end cover 12 are high at one end and low at the other end, so that the ears on two adjacent end covers can overlap and fit at one adjacent end, that is, only one mold is needed to produce the end cover with the ear structure; the number of molds is reduced, and the production cost of the enterprise is reduced; it can be understood that the ears at both ends of the end cover 12 can be of the same height, and the end cover with high ears needs to be used in conjunction with the end cover with low ears, and the number of molds will increase.

[0044] See Figure 2-Figure 12 As shown, in some embodiments of the utility model, the side wall of the end cover 12 is provided with a card slot 123, and the card slot 123 is at least two and arranged on the left and right, and also includes a connecting piece 3, and the connecting piece 3 is provided with two card blocks 31, one of the card blocks 31 is inserted into the card slot 123 of one end cover, and the other card block 31 is inserted into the card slot 123 of the other end cover, so as to fix the folded corners of two adjacent solar panel units 1. For details, see Fig.15As shown, when the solar panel structure is installed on the lamp pole, after the folding angle of two adjacent solar panel units is adjusted to the right position, the block 31 of the connecting piece 3 is inserted into the slot 123 on the two adjacent end caps 12, and the adjacent solar panel units are fixed by the connecting piece 3, thereby improving the structural strength after the folding angle is adjusted to the right position, facilitating the adjustment of the folding angle between other solar panel units, and finally facilitating the installation of the solar panel structure on the lamp pole. In addition, for solar panel structures with different numbers of sides, different connecting pieces are matched, so that the connecting piece can be directly used to lock the angle between two adjacent solar panel units, that is, there is no need to deliberately adjust the angle between the two solar panel units, but as long as the connecting piece can be inserted, the angle between the two solar panel units is determined and fixed, and the use of the connecting piece will greatly facilitate the installation of the solar panel structure.

[0045] See Fig.11 and Fig.12 As shown, in some embodiments of the present invention, the connecting piece 3 is in a V-shaped structure. In other embodiments, the connecting piece 3 may also be in a straight or L-shaped structure. Connecting pieces of different structures may be used in combination, for example, Figure 19-21 The required connecting pieces 3 include a straight-line connecting piece (used for connecting two parallel solar panel units 1) and an L-shaped connecting piece (used at a corner).

[0046] See Figure 2 and Fig.13 As shown, in some embodiments of the present invention, the solar panel assembly 11 includes a solar panel 111 and a side bracket 112, and the side bracket 112 is provided with a longitudinally extending clamping groove 1121. The side bracket 112 is arranged on the left and right sides of the solar panel 111 and clamps and fixes the solar panel 111. Therefore, the solar panel assembly 11 only needs aluminum side brackets 112 on both sides to fix the solar panel 111, avoiding the use of large-area flat aluminum to fix the solar panel 111, which can reduce material usage and production costs, and also reduce the overall weight of the solar panel structure.

[0047] See Figure 7-Figure 10 As shown, in some embodiments of the utility model, a fixing block 124 is provided at the lower end of the end cover 12, and the clamping groove 1121 of the side bracket 112 is clamped and fixed on the fixing block 124. The specific fixing method can be achieved by using screws 4, thereby, the fixation of the solar panel assembly 11 on the end cover 12 will become simple and reliable.

[0048] See Figure 7-Figure 10As shown, in some embodiments of the utility model, a limiting cavity 125 is provided at the bottom of the end cover 12, and the solar panel 111 extends into the limiting cavity 125 and is clamped and limited by the limiting cavity 125. On the one hand, the fixation of the solar panel 111 has more limits and is more reliable. On the other hand, the upper and lower ends of the solar panel 111 are hidden in the limiting cavity 125, thereby improving the aesthetics of the solar panel structure after installation.

[0049] See Figure 7 and Fig. 9 As shown, a protrusion 127 can be set on part of the end cover 12, and a corresponding groove 128 can be set on part of the end cover 12. When it is necessary to increase the solar panel structure in the height direction of the lamp pole, the upper and lower adjacent solar panel structures can be aligned through the cooperation of the protrusion 126 and the groove 127, so that the upper and lower solar panel structures are neat.

[0050] The second aspect of the present invention also provides a street lamp, comprising a lamp pole, and also comprising the solar panel structure described in any one of the embodiments of the first aspect, wherein the solar panel structure is fixed on the lamp pole.

[0051] The embodiments of the utility model are described in detail above in conjunction with the accompanying drawings, but the utility model is not limited to the above embodiments. Various changes can be made within the knowledge scope of ordinary technicians in the relevant technical field without departing from the purpose of the utility model.
