DETAILED DESCRIPTION

[0033] To make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0034] A portable solar charger according to a preferred embodiment of the present invention will be described in detail below. Figure 1-11 As shown, a portable movable solar charging device includes a base plate 1, a front cover plate 2 is connected to the front side of the top of the base plate 1 for limited rotation, a rear cover plate 3 is connected to the rear side of the top of the base plate 1 for limited rotation, side covers 4 are connected to the left and right sides between the front cover plate 2 and the rear cover plate 3 at the top of the base plate 1 for limited rotation, photovoltaic components 5 are arranged on the inner sides of the front cover plate 2, the rear cover plate 3 and the side cover plate 4, a charging component 6 is arranged in the center of the top of the base plate 1, a fixed roller 7 is fixedly installed on the front side of the bottom end of the base plate 1, and a universal wheel 8 is fixedly installed on the rear side of the bottom end of the base plate 1.

[0035] The top of the rear cover plate 3 is connected to the top cover plate 9 for limiting rotation. A limiting shaft 10 is symmetrically fixedly installed on the end of the top cover plate 9 away from the rear cover plate 3. The end of the limiting shaft 10 away from the top cover plate 9 is connected to the positioning handle 11 for limiting rotation. The top of the front cover plate 2 is symmetrically provided with a limiting groove 21. The limiting groove 21 is aligned with the limiting shaft 10, and the limiting groove 21 is adapted to the limiting shaft 10. Therefore, by utilizing the cooperation between the limiting shaft 10, the positioning handle 11 and the limiting groove 21, the top cover plate 9 can be limited by the front cover plate 2.

[0036] A positioning convex plate 41 is fixedly installed on the top end of the side cover plate 4, and positioning holes 91 are symmetrically opened on the left and right sides of the top cover plate 9, and the positioning holes 91 are adapted to the positioning convex plate 41. Therefore, the top cover plate 9 can be used to limit the side cover plate 4 by snapping the positioning holes 91 on the top cover plate 9 with the positioning convex plate 41.

[0037] The front end of the front cover plate 2 is symmetrically fixed with a mounting column 12, and the top of the mounting column 12 is internally limited and slidably connected with a pulling rod 13 to facilitate pulling and moving.

[0038] The photovoltaic assembly 5 includes a solar panel 51, and the inner sides of the front cover plate 2, the rear cover plate 3 and the side cover plate 4 are all connected to the solar panel 51 in a limited rotation manner. A groove 52 is opened on the middle part of the solar panel 51 close to the front cover plate 2, the rear cover plate 3 and the side cover plate 4. The groove 52 passes through the solar panel 51 up and down. A limiting rod 53 is connected to the inner side of the front cover plate 2, the rear cover plate 3 and the side cover plate 4 on the top of the base plate 1 in a limited rotation manner. The limiting rod 53 passes through the groove 52 upward and is connected to the solar panel 51 in a limited rotation manner in the groove 52.

[0039] The solar panels 51 are evenly distributed up and down on the inner side of each front cover plate 2, rear cover plate 3 and side cover plate 4, and all the solar panels 51 on the inner side of the front cover plate 2, rear cover plate 3 and side cover plate 4 are staggered up and down, so that within a certain space, more solar panels 51 are distributed inside the space enclosed by the front cover plate 2, rear cover plate 3 and side cover plate 4.

[0040] The charging assembly 6 includes an electric control box 61 , which is fixedly mounted at the center of the top of the bottom plate 1 , and a turntable 62 is rotatably connected to the top of the electric control box 61 , and a charging panel 63 is evenly fixedly mounted on the periphery of the turntable 62 .

[0041] The solar panel 51 can generate electricity on both the upper and lower surfaces. The inner sides of the front cover 2, the rear cover 3 and the side cover 4 are all attached with reflective films, which can reflect light to the bottom surface of the solar panel 51 when opened, so that both sides of the solar panel 51 can generate electricity.

[0042] The working principle of the present invention is:

[0043] After the solar charging device is moved to the specified position, the positioning handle 11 is first rotated to align it with the limit groove 21 to release the limit fixation between the front cover 2 and the top cover 9, and then the top cover 9 can be flipped upward. During the flipping process, the positioning hole 91 on the top cover 9 can also be disengaged from the positioning protrusion 41, thereby releasing the limit fixation between the top cover 9 and the side cover 4.

[0044] Then the front cover 2, the rear cover 3 and the side cover 4 are flipped outward and unfolded at the same time. During the unfolding process, the solar panel 51 is connected to the inner sides of the front cover 2, the rear cover 3 and the side cover 4 by limiting the rotation connection, and the limiting rod 53 passes through the solar panel 51, and the limiting rod 53 is connected to the solar panel 51 by limiting the rotation connection in the groove 52 in the middle of the solar panel 51. During the flipping of the front cover 2, the rear cover 3 and the side cover 4 outward, the solar panel 51 can be driven to unfold outward in a step-like manner, and the solar panel 51 can always remain in a horizontal state, which is conducive to power generation.

[0045] After unfolding, the direction of the unfolded solar charging device can be adjusted according to the lighting conditions through the coordinated design of the fixed roller 7 and the universal wheel 8 at the bottom end of the base plate 1. At the same time, the inner sides of the front cover plate 2, the rear cover plate 3 and the side cover plate 4 are all attached with reflective film. When the light is oblique, the stepped unfolded solar panel 51 can have a larger area illuminated by sunlight. Under the effect of the reflection of the reflective film, the bottom surface of the solar panel 51 can also generate electricity, thereby ensuring the efficiency of power generation.

[0046] After the front cover 2, the rear cover 3 and the side cover 4 are unfolded, the charging panel 63 on the side of the turntable 62 at the top of the electric control box 61 can be exposed, which is convenient for charging operations. At the same time, the turntable 62 can be rotated as needed to adjust the direction of the charging panel 63.

[0047] After charging is completed, first flip the side covers 4 on both sides upward to reach a vertical state, then flip the front cover 2 upward to reach a vertical state, and finally flip the rear cover 3, so that the front cover 2 and the rear cover 3 clamp the side cover 4, and at the same time flip the top cover 9 downward to make the positioning hole 91 and the positioning convex plate 41 at the top of the side cover 4 complete the sleeve limit, and at the same time the limiting shaft 10 can also fall into the limiting groove 21, and then the positioning handle 11 is rotated to complete the fixed limit between the top cover 9 and the front cover 2, and then the front cover 2, the rear cover 3, the side cover 4 and the top cover 9 are contracted and fixed, and a closed space is formed. During the contraction process, the solar panel 51 can also be staggered and contracted into the closed space, and at the same time the charging component 6 can be wrapped, so as to protect the photovoltaic component 5 and the charging component 6.

[0048] After the shrinking and assembling is completed, by pulling the pulling rod 13 upwards, in cooperation with the fixed roller 7 and the universal wheel 8 at the bottom end of the base plate 1, the solar charging device can be conveniently carried and moved.

[0049] The above description of the disclosed embodiments enables one skilled in the art to implement or use the present invention. Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
