The power supply panel 2 is provided with a control unit for controlling the voltage and current according to the number of expanded battery packs 3 installed.

[0028] In this embodiment, when camping outdoors, the number of expansion battery packs 3 required is selected according to the camping time, and each expansion battery pack 3 is connected in sequence by the fixing component 4 and connected to the power supply panel 2.

[0029] Specifically, when installing the expanded battery pack 3, the top of the battery body 31 is inserted into the battery slot at the bottom of the power supply panel 2. The bottom of the power supply panel 2 is provided with a conductive plate, and the position of the conductive plate corresponds to the positive and negative terminals of the battery body 31. After inserting the battery into the bottom of the power supply panel 2, the mounting frame 32 is pushed so that the mounting frame 32 contacts the bottom wall of the power supply panel 2. The connecting buckles 42 on both sides are pushed so that the connecting buckles 42 flips upward and the insertion buckle 43 at the top of the connecting buckle 42 is inserted into the inside of the buckle groove 44, thereby achieving the purpose of fixing the mounting frame 32 to the power supply panel 2. Similarly, the two expanded battery packs 3 are connected to each other.

[0030] This allows the number of expanded batteries to be adaptively selected based on usage time, thereby improving the applicability of the power bank.

[0031] In a further preferred embodiment of this utility model, such as Figure 3 and Figure 5 As shown, magnets are provided on the side of the slot 44 and the buckle 43 respectively, and the two magnets can attract each other when the buckle 43 is inserted into the slot 44.

[0032] In this embodiment, since a magnet is provided on the side of the snap-fit ​​groove 44 corresponding to the snap-fit ​​buckle 43 and they can attract each other, when the snap-fit ​​buckle 43 is inserted into the inside of the magnet, the snap-fit ​​buckle 43 can be effectively attracted, thus preventing the snap-fit ​​buckle 43 from falling off.

[0033] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the angle adjustment component 5 includes a linkage component and a support component. The linkage component includes a strip plate 51, and both ends of the strip plate 51 are provided with rotating shafts 52. The two rotating shafts 52 are rotatably connected to the outer shell of the projector body 1 and the side wall of the power supply panel 2, respectively.

[0034] In this embodiment, the projector body 1 is rotatably connected to the power supply panel 2 via the strip plate 51 and two rotating shafts 52, and the tilt angle of the projector body 1 is adjusted by the support assembly to facilitate outdoor use of the projector.

[0035] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the support assembly includes an arc-shaped guide rail 53, which is fixedly installed on the side wall of the projector body 1. A sliding shaft 54 ​​is provided inside the arc-shaped guide rail 53, and a support rod 55 is provided at the end of the sliding shaft 54. The end of the support rod 55 away from the sliding shaft 54 ​​is rotatably connected to the power supply panel 2 through a shaft.

[0036] In this embodiment, by lifting the support rod 55, the support rod 55 pushes the arc-shaped guide rail 53 to control the distance between the projector body 1 and the power supply panel 2, thereby achieving the purpose of making the projector body 1 tilt.

[0037] In a further preferred embodiment of this utility model, such as Figure 2 As shown, the bottom end of the support rod 55 is hinged to a positioning rod 56, and the power supply panel 2 has several evenly distributed positioning slots 57 at positions corresponding to the positioning rod 56.

[0038] In this embodiment, the positioning rod 56 and different positioning slots 57 are used to fix the support rod 55 at different angles.

[0039] In a further preferred embodiment of this utility model, such as Figure 4 As shown, the supporting component 6 includes a connecting platform 61, an outer flange 62 is provided at the bottom of the outer peripheral wall of the connecting platform 61, the top of the connecting platform 61 is inserted into the interior of the mounting frame 32, a plurality of insert rods 63 are provided inside the outer flange 62, and the mounting frame 32 has insertion holes at positions corresponding to the insert rods 63.

[0040] In this embodiment, when the plug 63 is inserted into the socket through the setting of the outer flange 62, the magnet at the top of the plug 63 and the magnet inside the socket attract the outer flange 62. The top of the connecting platform 61 is provided with a conductive structure for connecting the circuit inside the battery body 31. When the top of the battery body 31 is in contact with the top of the power supply panel 2 and the bottom is in contact with the conductive structure at the top of the connecting platform 61, the projector can be powered through the battery body 31.

[0041] And as Figure 5 As shown, the bottom end of the connecting plate 42 is L-shaped. After the outer flange 62 contacts the mounting frame 32, it can limit the bottom end of the connecting plate 42 to prevent the connecting plate 42 from flipping over, which can effectively improve the stability of the battery connection. Similarly, when two expanded capacity battery packs 3 are connected to each other, the top end of the mounting frame 32 can also limit the bottom end of the connecting plate 42.

[0042] The embodiments described herein are preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
