Detailed Implementation
[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0028] Example 1:
[0029] like Figures 1 to 11 As shown, this embodiment provides a solar charging backrest box for electric vehicles, including a backrest 11 installed at the rear of the electric vehicle body 1. A support frame is installed on the rear side of the backrest 11 by screws. The support frame includes an upright plate 211 fixedly installed on the rear side of the backrest 11 and a support plate 22 hinged to the top of the upright plate 211 by a hinge shaft 23. A fastening component is provided at the end of the hinge shaft 23. The backrest box 3 is fixedly installed on the upper surface of the support plate 22 by screws.
[0030] Please see Figure 11 As shown, the backrest box 3 includes a box body 31 and a box cover 32; the outer front part of the box cover 32 is hinged to the outer front part of the box body 31; inside the box body 31 are placed a foldable solar panel 8, two fiber bandages 5, and two support rods 6, the support rods 6 are hinged to the upper rear end face of the box body 31, and one end of the fiber bandage 5 is tightly bound to the end of the support rod 6; a support plate 321 is hinged to the top of the box cover 32. Furthermore, an end platform 34 is provided on the rear side inside the box body 31, the upper surface of the end platform 34 is flush with the upper end face of the box body 31, to ensure that the support rods 6 can be horizontally positioned on the end platform 34 after rotation. The two support rods 6 are rotatably mounted on the upper surface of the end platform 34. A locking element 33 is provided inside the end platform 34 for locking the box body 31 and the box cover 32. The locking element 33 is existing technology and will not be described in detail here. Further details can be found in [link to relevant documentation]. Figure 10As shown, the upper surface of the cover 32 is provided with a support plate groove 322, and the support plate 321 is hinged between the two side walls of the support plate groove 322. Magnets are embedded in the end of the support plate 321 and the bottom surface of the support plate groove 322. When the cover 32 is open and in a horizontal state, the support plate 321 is vertically supported on the electric vehicle seat. When the cover 32 is closed and in a retracted state, the support plate 321 is matched and installed in the support plate groove 322, and the two magnets are attracted to each other, which is safe and stable.
[0031] When the backrest box 3 is in working condition, under the action of the fastening components and the support plate 321, the box body 31 and the box cover 32 open upwards and are in a horizontal position; the other end of the fiber bandage 5 is tightly tied to the handlebar 12, and the foldable solar panel 8 is unfolded and placed on the two fiber bandages 5; as Figure 6 and Figure 7 As shown, the foldable solar panel 8 is in a nine-square grid shape, and the two fiber straps 5 are stretched to provide support for the foldable solar panel 8. At the same time, the box body 31 and the box cover 32 are in a horizontal state to provide support for the foldable solar panel 8.
[0032] When the backrest box 3 is in the retracted state, the two fiber straps 5, the foldable solar panel 8, and the two support rods 6 are folded and then rotated and stored inside the backrest box 3. The box body 31 and the lid 32 are locked in a closed state by the locking device 33. Under the action of the fastening component, the backrest box 3 is vertically fixed to the rear side of the upright plate 21. After the box body 31 and the lid 32 are closed and locked, the backrest box 3 is released by the fastening component, and then the backrest box 3 is rotated from... Figure 9 Status restored to Figure 8 The object is then secured using fastening components to maintain a stable placement.
[0033] For further details, please refer to Figure 3 and Figure 5 As shown, the fastening assembly includes a handle 41 hinged to the end of the hinge shaft 23. Symmetrical protrusions 211 are provided on both sides of the top of the upright plate 211, and the protrusions 211 are hinged to the lower protrusion 221 of the support plate 22 via the hinge shaft 23. A cam 42 is integrally provided at the end of the handle 41, and the cam 42 is rotatably mounted on the periphery of the end of the hinge shaft 23. When the end of the handle 41 is vertically attached to the side of the upright plate 21, the protrusion of the cam 42 presses against the side of the upright plate 21, causing the nut 231 at the end of the hinge shaft 23 to press against the lower protrusion 221 and the protrusion 211, thereby fixing the housing 31 to the upright plate 21 and maintaining the stability of the backrest box 3. When the end of the handle 41 rotates away from the side of the upright plate 21, the protrusion of the cam 42 moves away from the side of the upright plate 21, causing the lower protrusion 221 and the protrusion 211 to release, thereby allowing the housing 31 to rotate relative to the upright plate 21. That is, by rotating the handle 41, the position of the protrusion of the cam 42 is adjusted, thereby releasing or tightening the backrest box 3, which makes it convenient to adjust the state of the backrest box 3 or tighten and stabilize the state of the backrest box 3.
[0034] For further details, please refer to Figures 8 to 11 As shown, an L-shaped buckle 24 is integrally provided at the top center of the upright plate 21. The L-shaped buckle 24 is snapped onto the top of the backrest 11. The horizontal section of the horizontal plate of the L-shaped buckle 24 is provided. When the backrest box 3 is in working state, the horizontal section of the horizontal plate of the L-shaped buckle 24 supports the box body 31. The L-shaped buckle 24 makes it easy to install the upright plate 21 on the top of the backrest 11, and at the same time, the horizontal plate of the L-shaped buckle 24 can provide support for the box body 31 in a horizontal state.
[0035] For further details, please refer to Figure 7 As shown, the two fiber bandages 5 are connected by a horizontal strap 51. Several Velcro straps 52 are evenly distributed on the lower surface of the foldable solar panel 8 along the direction of the fiber bandages 5. The fiber bandages 5 are connected to the lower surface of the foldable solar panel 8 through the several Velcro straps 52. When the foldable solar panel 8 is unfolded into a nine-square grid shape, the fiber bandages 5 are connected to the lower surface of the foldable solar panel 8 through the Velcro straps 52 to ensure the stable placement of the foldable solar panel 8.
[0036] For further details, please refer to Figure 11 As shown, a boost charging controller 7 is placed inside the housing 31. The power output terminal of the foldable solar panel 8 is connected in parallel to the boost charging controller 7. The power supply head of the boost charging controller 7 is connected to the charging terminal of the electric vehicle body 1. Under suitable weather conditions, i.e., no rain, no wind, and sunshine, the unfolded foldable solar panel 8 converts solar energy into electrical energy, which is then used to charge the electric vehicle body 1 through the boost charging controller 7. This saves energy, is green and environmentally friendly, and is safe and convenient.
[0037] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
