[0030] See also Figures 1 to 4 The utility model provides a solar street light assembly, comprising: a shell assembly 100, the shell assembly 100 comprises a head end shell 110, a tail end shell 130 and at least one middle shell 120 spliced ​​between the head end shell 110 and the tail end shell 130, the head end shell 110, the middle shell 120 and the tail end shell 130 are spliced ​​in sequence to form a long strip-shaped cavity with an open opening upward, a plug-in sleeve 200 is provided at one end of the head end shell 110 away from the middle shell 120, an open photovoltaic panel 300 with a closed cavity is installed on the shell assembly 100, and the shell assembly 100 is provided with a light-emitting assembly 400 electrically connected to the photovoltaic panel 300 and arranged along the length direction of the shell assembly 100.

[0031] The solar street light assembly of the above structure can change the length dimension of the shell assembly 100 by changing the number of the middle shells 120 located between the head end shell 110 and the tail end shell 130. The length dimension of the lamp body can be flexibly changed according to the use requirements, so as to produce solar street light assemblies of various length specifications. There is no need to configure molds of different specifications according to solar street light assemblies of different length specifications, which is beneficial to reducing mold costs and has positive significance for the production and manufacturing of solar street light assemblies of different length sizes in the same series.

[0032] See also Figure 3 and Figure 4In some embodiments of the utility model, the head end shell 110 has a rectangular first bottom plate 111, and the three sides of the first bottom plate 111 are connected to the first enclosure 112 bent upward. The tail end shell 130 has a rectangular second bottom plate 131, and the three sides of the second bottom plate 131 are connected to the second enclosure 132 bent upward. The middle shell 120 has a rectangular plate 121, and the length direction of the rectangular plate 121 is arranged along the width direction of the shell assembly 100. Both ends of the rectangular plate 121 are provided with a bent plate portion 122 bent upward. The remaining side of the first bottom plate 111 and the side edge of the adjacent rectangular plate 121, the remaining side of the second bottom plate 131 and the side edge of the adjacent rectangular plate 121, and the adjacent rectangular plates 121 are all connected by a splicing mechanism 500, and the first enclosure 112, all the bent plate portions 122 and the second enclosure 132 together form an opening of the cavity. It is understandable that both the head end shell 110 and the tail end shell 130 have a side without a panel, so that the head end shell 110, the middle shell 120 and the tail end shell 130 can be sequentially spliced ​​together to form a cavity without partitions, which is conducive to accommodating parts. The first panel 112, all the bent plate portions 122 and the second panel 132 together form an opening of the cavity for installing and limiting the photovoltaic panel 300.

[0033] See also Figures 2 to 4 In some embodiments of the utility model, the splicing mechanism 500 includes a plurality of first threaded columns 510 arranged at intervals along the width direction of the shell assembly 100 and a plurality of first positioning seats 520 matched with the first threaded columns 510, the first threaded columns 510 are provided with first threaded holes 511 in the up and down directions, the first positioning seats 520 are provided with first through holes 521 for screws to pass through and facing the corresponding first threaded holes 511, a plurality of first threaded columns 510 and a plurality of first positioning seats 520 are respectively provided on the two side edges of the rectangular plate 121, one of the side edges of the first bottom plate 111 close to the rectangular plate 121 and the side edges of the second bottom plate 131 close to the rectangular plate 121 is provided with a plurality of first threaded columns 510, and the other is provided with a plurality of first positioning seats 520. It should be noted that a plurality of first threaded columns 510 are arranged at intervals on one side of the rectangular plate 121, and a plurality of first positioning seats 520 are arranged at intervals on the other side of the rectangular plate 121, so as to realize the splicing between the plurality of middle shells 120. When the first through hole 521 of the first positioning seat 520 is aligned with the first threaded hole 511, the screw passes through the first through hole 521 and is tightened in the first threaded hole 511 to realize the fixation after splicing and prevent separation. In this embodiment, a plurality of first threaded columns 510 are arranged at intervals on the side of the first bottom plate 111 close to the rectangular plate 121, and a plurality of first positioning seats 520 are arranged at intervals on the side of the second bottom plate 131 close to the rectangular plate 121. Of course, in other embodiments, the splicing mechanism 500 can also be replaced by a mortise and tenon structure or a snap-fit ​​structure.

[0034] See also Figure 4 In some embodiments of the utility model, in order to prevent the two components connected by the above-mentioned splicing mechanism 500 from being offset, the contour shape of the first threaded column 510 is a quadrangular prism, and the first positioning seat 520 is provided with a rectangular embedding groove 522 matching the contour shape of the first threaded column 510. The rectangular embedding groove 522 has a horizontal opening for the first threaded column 510 to be embedded therein, and the first through hole 521 penetrates the top wall of the rectangular embedding groove 522 in the up and down direction, which is conducive to conveniently splicing the shell assembly 100 in the horizontal direction.

[0035] See also Figure 1 As shown in FIG. 3 , in some embodiments of the utility model, the first bottom plate 111 is located below the rectangular plate 121 and the second bottom plate 131, and a storage space for accommodating a control module electrically connected to the light-emitting assembly 400 is defined between the first bottom plate 111 and the first enclosure 112. The above structure not only provides a storage location for the control module or other electrical components, but also avoids unnecessary increase in the thickness of the middle shell 120 and the tail shell 130. The height of the rectangular plate 121 and the second bottom plate 131 are level, and the light-emitting assembly 400 includes a plurality of lamp panels 410 respectively mounted on the lower end surface of the rectangular plate 121 and the lower end surface of the second bottom plate 131, which is conducive to making full use of the highly level area to arrange the light-emitting assembly 400, so that the solar street light assembly of the utility model has a higher illumination, and the control module and the light-emitting assembly 400 are staggered, reducing the influence of the heat generated by the control module on the lamp panel 410.

[0036] See also Figure 4 In some embodiments of the utility model, the lower end surface of the rectangular plate 121 and the lower end surface of the second bottom plate 131 are provided with a mounting groove 600 matching the corresponding light board 410, and the rectangular plate 121 and the second bottom plate 131 are provided with a wire hole 610 that passes through the mounting groove 600 from top to bottom, and each mounting groove 600 is installed with a light-transmitting plate 420 that clamps and fixes the light board 410. It should be noted that before the middle shell 120 is spliced, the corresponding light board 410 can be placed in the mounting groove 600, and then the light-transmitting plate 420 is installed in the mounting groove 600 to prevent the light board 410 from being separated from the middle shell 120, thereby facilitating the overall assembly of the solar street light assembly. Similarly, the light board 410 on the tail end shell 130 is also assembled in the same way, and the wires of the light board 410 are introduced into the cavity of the shell assembly 100 from the wire hole 610, which is convenient for the electrical connection between adjacent light boards 410.

[0037] See also Figure 2 and Figure 3In some embodiments of the utility model, the head end housing 110 is provided with a mounting opening 113 that matches the shape and size of the first bottom plate 111. One side of the first bottom plate 111 is rotatably connected to a side edge of the mounting opening 113 through a hinge 700. The side of the first bottom plate 111 opposite to the hinge 700 can swing upward to close the mounting opening 113 or swing downward to open the mounting opening 113. The side of the first bottom plate 111 opposite to the hinge 700 is tightened to the bottom of the head end housing 110 through a threaded fastener. It should be noted that when a component of the control module fails, it is only necessary to unscrew the threaded fastener, and then drive the first bottom plate 111 to rotate around the pivot of the hinge 700, and the maintenance personnel can directly repair the control module through the mounting opening 113.

[0038] See also Figure 2 and Figure 3 In some embodiments of the utility model, the shell assembly 100 has a circle of annular limiting walls 140 that abut against the contour edge of the photovoltaic panel 300, and a circle of annular water-isolating grooves 150 are provided on the inner side of the annular limiting wall 140. A water collecting groove and a drainage hole 160 that penetrates the water collecting groove are provided on the bottom wall of the inner surface of the shell assembly 100. It should be noted that although the photovoltaic panel 300 and the annular limiting wall 140 are fixed by adhesive, the sealing effect is still poor and water seepage may occur. If water enters the shell assembly 100 from the gap between the photovoltaic panel 300 and the annular limiting wall 140, the water will be separated by the annular water-isolating groove 150 and cannot penetrate further. Even if some water vapor enters the inner surface of the shell assembly 100, it can be discharged downward through the drainage hole 160 of the water collecting groove after condensing into water droplets.

[0039] See also Figure 2 and Figure 3 In some embodiments of the utility model, in order to adjust the illumination angle of the solar street light assembly, an arc plate 210 is provided at one end of the plug-in sleeve 200, and the outer side wall of the head end shell 110 is provided with an arc mounting surface that fits the arc plate 210, and a threaded mounting hole 170 is provided on the arc mounting surface.

[0041] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
