[0007] Furthermore, a controller is fixedly connected in the cavity, and a lamp bead is provided on the controller.

[0008] Furthermore, a clamping slot is provided on a side wall of one side of the adjustment slot, and a second electromagnet is provided on a side wall of the other side.

[0009] Furthermore, the adjustment component includes a permanent magnet slidably connected to the adjustment slot, the permanent magnet is fixedly connected to the adjustable convex lens, and a card block for inserting into the card slot is fixedly connected to a side of the permanent magnet close to the card slot.

[0010] Furthermore, a spring is fixedly connected to a side of the permanent magnet close to the second electromagnet.

[0011] Furthermore, a control button for manual adjustment is fixedly connected to the permanent magnet.

[0012] Furthermore, a mounting frame for mounting on a bicycle is fixedly connected to the headlight housing.

[0013] Furthermore, a first electromagnet for attracting and repelling the permanent magnet is provided at one end of the adjustment slot close to the front cover.

[0014] Compared with the prior art, the utility model has the following beneficial effects: the utility model can control the position of the adjustable convex lens by adjusting the component to achieve the change of the aperture size, and the adjusting component can be switched between automatic and manual.

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model are described clearly and completely below. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1 , Figure 2 and Figure 3 The present embodiment provides a bicycle headlamp, including a headlamp housing 11, a cavity 19 penetrating one end of the headlamp housing 11 is provided in the headlamp housing 11, a front cover 12 is fixedly connected to the open end of the headlamp housing 11, a controller 18 is fixedly connected in the cavity 19, and a lamp bead 17 is provided on the controller 18.

[0024] A lens is installed in the front cover 12 of the headlight housing 11. Different types of lenses, such as a plane lens or a convex lens, can be installed according to user needs.

[0025] Several buttons connected to the controller 18 should be provided on the handlebar, including but not limited to a switch for controlling the lamp bead 17 , a button for controlling the magnetic pole state and start of the first electromagnet 26 , and a switch for controlling the second electromagnet 27 .

[0026] See also Figure 2 , Figure 4 , Figure 5 and Figure 6 The cavity 19 is provided with an adjustable convex lens 13 which is slidably connected along the height direction of the cavity 19 .

[0027] The height direction mentioned herein is relative to the opening direction of the cavity 19 , and when the opening direction is upward, the height direction specifically refers to a straight line moving from the bottom wall of the cavity 19 toward the front cover 12 .

[0028] The inner wall of the cavity 19 is provided with an adjustment slot 24 penetrating the headlight housing 11, and a side wall of one side of the adjustment slot 24 is provided with a clamping slot 20;
