Wherein, 1, lamp main body; 101, illuminating lamp; 102, controller; 103, taillight; 104, USB interface; 105, charge circuit; 106, battery pack; 107, booster circuit; 108, switch; 2, support; 3, holder.

The specific embodiment

Below in conjunction with the drawings and specific embodiments, the utility model is described in more detail.

As shown in Figure 1, the structure division of the utility model bicycle use headlight is as follows: described bicycle use headlight comprises lamp main body 1, support 2 and holder 3, the front end of lamp main body 1 is provided with the illuminating lamp 101 being connected with power supply, the lower end detouchable of the upper end of support 2 and lamp main body 1 links together, rotating the linking together in lower end of holder 3 and support 2, holder 3 is for fixing and make lamp main body 1 be fixed on bicycle with cycle frame, certainly, the structure of support 2 and holder 3 can change arbitrarily, lamp main body 1, connection structure between support 2 and holder 3 also can change arbitrarily as required.

The rear end of described lamp main body 1 is also provided with the taillight 103 being connected with power supply, the axis of described taillight 103 is inclined upwardly, the axis of taillight 103 is the L1 shown in Fig. 1 namely, the angle of the axis of L1 and lamp main body 1 is the included angle B shown in Fig. 1, included angle B is 40 degree, while making taillight 103 luminous, and the optical axis of taillight 103 40 degree that are inclined upwardly, certainly, included angle B also can be chosen any number within the scope of 20 ~ 50 degree as required.

As shown in Figure 2, the circuit part of the utility model bicycle use headlight is as follows: the lamp main body 1 of described bicycle use headlight is provided with usb 1 04, switch 108, charge circuit 105, battery pack 106, booster circuit 107 and controller 102, the mouth of usb 1 04 is electrically connected with the input end of battery pack 106 by charge circuit 105, the mouth of battery pack 106 electrically connects as controller 102 by booster circuit 107 with the input end of controller 102 and powers, the mouth of battery pack 106 is electrically connected the voltage that makes controller 102 detect battery pack 106 with the input end of controller 102, the mouth of controller 102 is electrically connected with the on-off element in charge circuit 105 break-make that makes controller 102 control charge circuit 105, switch 108 is electrically connected with the signal input part of controller 102, two power output ends of controller 102 are electrically connected with illuminating lamp 101 and taillight 103 respectively, above-mentioned charge circuit 105 and booster circuit 107 are routine techniques, here do not elaborate, above-mentioned switch 108 is signal switch, often click switch 108, switch 108 sends a control signal to controller 102, controller 102 can judge that battery pack is that (voltage of single-unit rechargeable battery is 1.2V for rechargeable battery or general dry battery by detecting the output voltage of battery pack 106, the voltage of single-unit general dry battery is 1.5V, in the utility model, two batteries can be installed simultaneously), when usb 1 04 is pegged graft after upper charging wire, if controller 102 detects that battery pack 106 is for rechargeable battery, controller 102 is controlled the on-off element closure in charge circuit 105, make charge circuit 105 conductings, now charging wire charges to rechargeable battery by usb 1 04, if controller 102 detects that battery pack 106 is for general dry battery, the on-off element that controller 102 is controlled in charge circuit 105 disconnects, charge circuit 105 is disconnected, now the electric current of usb 1 04 cannot be transported to battery pack by charge circuit 105, can avoid causing the accident to general dry battery charging.
