Description

Technical Field

[0001] The utility model relates to the field of outdoor batteries, in particular to a foldable solar energy storage battery. Background Art

[0002] During outdoor activities, solar energy storage batteries can be charged by sunlight, so they can be charged outdoors in a portable manner. However, since the charging efficiency of solar energy storage batteries is not high, the solar panels need to be unfolded and their contact area with sunlight needs to be maximized when in use to improve the charging efficiency. Existing foldable solar energy storage batteries usually set a complex rotating structure between the solar panel and the battery body so that the solar panel can remain unfolded after being unfolded. However, the supporting force of this structure decreases after repeated use, and the complex structure is easy to damage, which affects the unfolding and use of the solar panel, thereby reducing the charging efficiency of the solar energy storage battery.

[0028] See also Figure 1-4 The present application provides a foldable solar energy storage battery, including a body 1, a solar panel 2, a support and positioning mechanism 3, a battery 4 and a controller 5. One end of the solar panel 2 is rotatably connected to the body 1; one end of the support and positioning mechanism 3 is connected to the lower end surface of the solar panel 2, and is used to support the solar panel 2 when the solar panel 2 is unfolded. When in use, after the solar panel 2 rotates around the body 1 to form a certain angle with the body 1, the support and positioning mechanism 3 fixes its unfolded state for charging. The battery 4 and the controller 5 are fixed in the body 1 and are electrically connected to the solar panel 2.

[0029] In this embodiment, the main body 1 is generally box-shaped, and the left and right sides thereof are provided with first receiving grooves 11 for receiving the solar panel 2 in a folded state.

[0030] Specifically, the upper ends of the solar panel 2 are provided with rotating shafts, and the upper ends of the opposite sides of the first receiving groove 11 are provided with through holes, and the rotating shafts are clamped in the through holes, so that the upper side of the solar panel 2 is rotatably connected with the body 1 along the upper side of the first receiving groove 11, and the light absorbing surface of the solar panel 2 is arranged away from the first receiving groove 11. When the solar panel 2 is unfolded and in a charging state, the light absorbing surface faces upward. Such an arrangement maximizes the area of ​​the solar panel 2.

[0031] Furthermore, a first wire-passing opening 111 is provided on the upper side of the bottom of the first receiving groove 11, and the first wire-passing opening 111 is connected to the inside and outside of the body 1 for passing wires. Preferably, the first wire-passing opening 111 is close to the bottom of the rotation axis of the solar panel 2 and the first receiving groove 11.

[0032] A wire-passing boss 21 is provided in the middle of the backlight surface of the solar panel 2. The inside of the wire-passing boss 21 is hollow and is used for passing wires. Correspondingly, a second wire-passing opening 211 is provided on the wire-passing boss 21. When the solar panel 2 is stored in the first receiving slot 11, the second wire-passing opening 211 is directly opposite to the first wire-passing opening 111. In the present application, the first wire-passing opening 111 and the second wire-passing opening 211 are arranged close to the rotation axis of the solar panel 2 and the first receiving slot 11, so that when the solar panel 2 is rotated around the body 1 to be unfolded or stored, it is not easily affected by the wire passing.

[0033] Furthermore, a convex edge 22 is provided along the periphery of the backlight surface of the solar panel 2. The convex edge 22 is used to disperse the force to prevent the solar panel 2 from being damaged by excessive impact when the solar panel 2 is stored.

[0034] Furthermore, the thickness of the over-line boss 21 and the convex edge 22 is consistent with the groove depth of the first receiving groove 11. When the solar panel 2 is received in the first receiving groove 11, the light-absorbing surface of the solar panel 2 is flush with the end face of the body 1, making the overall appearance of the solar energy storage battery more smooth and beautiful.

[0035] The support and positioning mechanism 3 includes a support plate 31. A second receiving groove 212 is provided at the center of the wire-passing boss 21 for receiving the support plate 31. One end of the support plate 31 is slidably connected to the side wall surface of the second receiving groove 212 close to the first wire-passing opening 111. In this embodiment, the length of the support plate 31 is less than or equal to the length of the second receiving groove 212 to ensure that the support plate 31 can be completely received in the second receiving groove 212. In other embodiments, the support plate 31 is a foldable plate, which is accommodated in the second receiving groove 212 after being folded.

[0036] Furthermore, a clamping groove 112 is provided at the center of the bottom of the first storage groove 11. When the solar panel 2 is unfolded and charged, the movable end of the support plate 31 is clamped in the clamping groove 112, so that the solar panel 2 can remain unfolded and stably charge. Furthermore, the bottom surface of the clamping groove 112 is arranged in a slope, and the groove depth of the lower side of the clamping groove 112 is gradually greater than the groove depth of the upper side of the clamping groove 112. The clamping groove 112 arranged on the groove bottom slope is conducive to guiding the support plate 31 to be clamped in the clamping groove 112.

[0037] Furthermore, the first receiving groove 11 is provided with an extended boss 113 along the lower side of the clamping groove 112, and the upper surface of the extended boss 113 is connected with the inner wall surface of the lower end of the clamping groove 112 to prevent the support plate 31 from falling when clamped.

[0038] Furthermore, the support and positioning mechanism 3 also includes a spring, which is also arranged at the rotation connection between the support plate 31 and the second receiving groove 212. When the movable end of the support plate 31 leaves the clamping groove 112, it automatically returns to its original position due to the spring and is received in the second receiving groove 212. The end of the extended boss 113 away from the clamping groove 112 protrudes from the inner wall surface of the lower end of the clamping groove 112, and is used to clamp the support plate 31 to prevent it from falling.

[0039] Furthermore, a buckle piece 23 is provided at the movable end of the solar panel 2 . When the solar panel 2 is received in the first receiving slot 11 , the buckle piece 23 protrudes from the lower end surface of the body 1 , making it convenient to manually grab the buckle piece 23 and unfold the solar panel 2 .

[0040] A positioning column 24 is provided on one surface of the buckle 23 close to the first receiving groove 11. Correspondingly, a semicircular groove 114 is provided on the lower side of the bottom of the first receiving groove 11. When the solar panel 2 is received in the first receiving groove 11, the positioning column 24 is clamped in the semicircular groove 114, so that the solar panel 2 can remain in the received state and will not easily fall out of the first receiving groove 11.

[0041] The battery 4 and the controller 5 are fixedly mounted in the body 1 , and both the battery 4 and the controller 5 are connected to the solar panel 2 via cables, and the cables pass through the first cable opening 111 and the second cable opening 211 .

[0042] Furthermore, it also includes a lamp body 6, a charging port 7, a switching power supply 8 and a wiring module 9, which are all arranged on the body 1 and are electrically connected to the battery 4 and the controller 5. Furthermore, the body 1 is also provided with a plurality of heat dissipation ports 12 for dissipating heat for the battery 4 and the controller 5 in the body 1. Furthermore, a handle 13 is provided on the upper end surface of the body 1 to facilitate carrying and moving the solar energy storage battery.

[0043] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and the utility model is also intended to include these modifications and modifications.
