[0023] To make the technical solution of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. Example

[0024] like Figure 1 and Figure 4 As shown, a dual-power headlamp includes a main body 11, a lithium battery 41, and a dry cell battery 42. Both the lithium battery 41 and the dry cell battery 42 can be used as power sources for the headlamp. At the same time, a charging port is provided on the end face of the lithium battery 41 to facilitate direct charging of the lithium battery 41 and improve charging efficiency.

[0025] The main body 11 is connected to the back shell 13. The back shell 13 and the main body 11 are detachably connected by a snap fastener. One side of the back shell 13 is rotatably connected to one side of the main body 11 to prevent the back shell 13 from falling off.

[0026] like Figure 2 As shown, a connecting shell 12 is connected to the end face of the back shell 13 away from the main body 11. The connecting shell 12 is used to install straps for easy wearing by the user.

[0027] like Figure 3 As shown, the headlamp also includes a battery compartment 21, which is detachably connected to the main body 11. The battery compartment 21 is located between the main body 11 and the back cover 13. The main body 11 is also provided with a circuit board 14, and the battery compartment 21 and the circuit board 14 are connected.

[0028] The battery compartment 21 has a mounting cavity 24 on the side facing the back cover 13. The mounting cavity 24 has an opening and extends through the top and bottom, making it convenient to install and remove the battery pack.

[0029] Contact grooves 28 are provided on both sides of the mounting cavity 24. The side walls of the contact grooves 28 are connected to the mounting cavity 24, which facilitates the insertion of the dry cell battery 42 or the lithium battery 41 into the contact grooves 28. Contact pieces are installed in the contact grooves 28 to facilitate the formation of a circuit by the battery.

[0030] like Figure 6 As shown, the contact pieces are divided into fixed contact pieces 26 and movable contact pieces 27. The fixed contact pieces 26 and movable contact pieces 27 are installed in parallel in the contact groove 28. The movable contact piece 27 has an extension. The contact groove 28 has a through connection hole 23 at the movable contact piece 27. The extension of the movable contact piece 27 passes through the connection hole 23, and the movable contact piece 27 is connected to the circuit board 14. The contact grooves 28 on both sides are respectively provided with movable contact pieces 27. The battery and the circuit board 14 form a ring-shaped passage through the contact pieces, thereby realizing power supply. The movable contact pieces 17 on both sides are arranged diagonally.

[0031] When the dry cell battery 42 is installed in the battery compartment 21, both ends of the dry cell battery 42 contact the movable contact piece 27 and the fixed contact piece 26 on both sides respectively, forming a loop.

[0032] When the lithium battery 41 is installed in the battery compartment 21, the lithium battery 41 only contacts the movable contact piece 27. There is one and only one power contact 44 fixedly installed on the side wall of the lithium battery 41. The power contact 44 abuts against the movable contact piece 27. The bottom wall of the mounting cavity 24 is provided with a contact hole 25 that penetrates the battery compartment 21. The side of the lithium battery 41 facing the bottom wall of the mounting cavity 24 is fixedly connected to the power contact 44. The power contact 44 passes through the contact hole 25 and contacts the circuit board 14, thereby realizing a loop between the lithium battery 41 and the circuit board 14.

[0033] By configuring the power-on contact 44 on the lithium battery 41, the occurrence of accidents caused by incorrect installation of the lithium battery 41 can be reduced.

[0034] Furthermore, the bottom wall of the mounting cavity 24 is provided with four contact holes 25, which facilitates the rotation and installation of the lithium battery 41, and allows it to make contact with the movable contacts 27 on both sides.

[0035] like Figure 5 and Figure 7 As shown, in order to prevent incorrect installation of the lithium battery 41 on the front or back, the bottom wall of the mounting cavity 24 is provided with four retaining strips 22 at the upper and lower openings. The retaining strips 22 are arranged symmetrically in pairs on both sides of the mounting cavity 24. The end face of the lithium battery 41 facing the bottom wall of the mounting cavity 24 is provided with a retaining groove 43. There are also four retaining grooves 43. The retaining grooves 43 and retaining strips 22 correspond one to one. When the lithium battery 41 is installed, the retaining strips 22 are embedded in the retaining grooves 43. At the same time, one side wall of the retaining groove 43 penetrates the side wall of the lithium battery 41 for easy disassembly.

[0036] Furthermore, the battery compartment 21 is also used to install dry cell batteries 42. The end of the retaining strip 22 is arc-shaped. When the dry cell battery 42 is installed in the mounting cavity 24, the retaining strip 22 and the side wall of the dry cell battery 42 abut against each other, which can better fix the dry cell battery 42. At the same time, when the arc-shaped retaining strip 22 extends into the slot 43, the arc-shaped end of the retaining strip 22 can deform, which can better clamp the lithium battery 41 and improve the connection strength.

[0037] The embodiments described above are merely illustrative of several implementations of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these modifications and improvements all fall within the scope of protection of the present invention. Therefore, the scope of protection of this patent should be determined by the appended claims.
