Abstract

The utility model relates to a movable bicycle headlight with a flashlight structure and a housing body. The front part of the housing body is provided with a light head with a spotlight shade while the rear part thereof is provided with a battery case cavity; an appropriate part on the surface of the housing body is equipped with an electric switch connecting batteries and a lamp bulb in the light head; a lower slot inside which at least a permanent magnet is arranged at the middle part of the housing body; the upper surface of the permanent magnet has a shape of a concave arc to form an assembly interface of the movable bicycle headlight. The utility model can be used as the bicycle headlight and a lighting device of an ordinary flashlight; when used as the bicycle headlight, the light can be instantly fixed by being simply placed on a steel pipe of a bicycle head frame and can be taken off by giving a slight screw; in addition, the utility model has small size and light weight, is easy to be carried with and has an outstanding effect of being double-purposed.

Description

A kind of portable bicycle head lamp

Technical field

But the utility model relates to the lighting device of a kind of double as bicycle lighting headlight and general lighting flashlight.

Background technology

The bicycle headstock lamp is of long duration, and bicycle headstock lamp the earliest is to cross friction drive motor rotation generating to the headlight power supply with being installed in the wheel bypass, this apparatus cost height, and extended immobilization is fragile onboard through exposing to wind and rain, now few usefulness.Have at present the lighting device that two kinds of headlight can be bicycle lighting headlight and general lighting flashlight dual-purpose on the market, wherein a kind of pistol type headlight that is referred to as, it is to be injection molded into one by flashlight and support, profile is as a pistol, and the buckle circle place that will be somebody's turn to do " pistol " makes a snare, is enclosed within on the headstock frame steel pipe, fixes with screw, there is the problem of loading and unloading trouble in this pistol type headlight, uses inconvenient.Another kind of headlight is with a flashlight and a support equipped formation with Shang Quan and following cast as " 8 " word, the following snare of figure of eight support is fixed with screw on the steel pipe of headstock frame, and being enclosed within going up of support, fixes with screw in the circle by flashlight, its each use also need mount and dismount, and uses inconvenient.

Summary of the invention

The purpose of this utility model be propose a kind of can with the flexible secure bond of bicycle headstock frame, can arbitrarily move or take off, small volume and less weight is convenient to carry, but the portable bicycle head lamp of the lighting device of double as bicycle lighting headlight and general lighting flashlight.

The portable bicycle head lamp that the utility model is designed, it is a flashlight structure, has a shell body, the front portion of this shell body is provided with the lamp holder with snoot, the rear portion is the battery case chamber, the electric switch that connects the bulb in battery and the lamp holder is arranged on the suitable position on shell body surface, it is characterized in that having a following Baltimore groove position at the middle part of shell body, in this groove position, be mounted with at least one permanent magnet, the lowest part of this permanent magnet upper surface is not less than the surface of shell body, forms the assembling interface of this portable bicycle head lamp.

Because the headstock frame of Regular Bicycle all has ferromagnetics tubular member, thereby as long as the assembling interface card on this portable bicycle head lamp housing is set on the pipe face of headstock frame, this portable bicycle head lamp can be fixed on the headstock frame in direct adhesive, permanent magnet in the described assembling interface can adopt neodymium iron boron, aluminium nickel cobalt or SmCo strong permanent magnet material, and the surface area of permanent magnet should be 40～240mm ², thickness makes it to have enough big magnetic bed knife in the scope of 3～10mm.The upper surface of described permanent magnet is preferably formed as cancave cambered surface shape along fore-and-aft direction, so that match with the pipe face of headstock frame, increases contact area between the two, thus strengthen headlight on the headstock frame in conjunction with stable degree.

If the headstock frame of bicycle is nonferromugnetic material members such as aluminium alloy or nonmetallic materials, then can be at the equipped ferromagnetism support that can match of the proper site of headstock frame, to support installing and fixing of this portable bicycle head lamp with the assembling interface on the utility model headlight housing.

The Lower Half available iron suitcase of the permanent magnet in the described assembling interface is wrapped up in, and both can strengthen the magnetic attraction of permanent magnet, also helps installing and fixing of permanent magnet.

In the both sides, front and back of described permanent magnet and fix the elastic buffering pad of preferably inlaying materials such as soft rubber or sponge between the Baltimore groove position of this permanent magnet, and make the highest point of a little higher than permanent magnet upper surface of this elastic buffering pad, make headlight on the headstock frame, have shake-proof ability preferably.

Bicycle head lamp of the present utility model, the both available general bulb of its light source recommends to adopt the LED lamp as light source, and power supply can be general battery, recommend to adopt the chargeable lithium cell that volume is little, capacity is high, especially the lithium battery that can share with handset compatibility.Adopt chargeable lithium cell to add and adopt the LED lamp source, favourable the utility model is realized energy-conservation and miniaturization.This bicycle head lamp, the shell body that also is flashlight structure can adopt the multiple shape that can match with the bicycle headstock, is generally cuboid or cylindrical shape, if adopt the LED lamp as light source, the suitable cuboid that adopts forms square headlight elegant in appearance.The size of this bicycle head lamp, the full-size of its long (L), wide (D), high (H) is respectively at 30～100mm, and 20～60mm is advisable in 10～40mm scope.

The utlity model has following outstanding advantage: in the time will using as the bicycle head lamp, as long as will one put and to fix with the headstock frame is identical automatically on the steel pipe of this portable bicycle head lamp on the headstock frame, and when the user will leave bicycle, only need one to twist and this portable bicycle head lamp can be taken off conveniently, mount and dismount operation without any need for erecting tools.And this portable bicycle head lamp also can use as common flashlight at any time easily owing to small and exquisite, light, portable, have the outstanding effect of dual-use material.
