Description

Headlamp

Technical field

The present invention relates to a kind of for two wheeler, the headlamp (Frontscheinwerfer) that is particularly useful for bicycle, electric bicycle (E-Bike), electric motor car (Pedelec) etc., it, with housing, is provided with the circuit board controlling LED wherein；With accommodating the lighting unit of LED, its have in the case of making full use of reflector and diffusing glass with road traffic or emission characteristics that the requirement of legal provisions matches.

Background technology

In the headlamp of the type mentioned by beginning the disclosedest file DE 10 2,010 037 174 it is known that wherein, headlamp shown herein is designed to be accommodated discretely in the housing by all parts and they be releasably connected with this housing discretely.

Summary of the invention

Therefore, it is an object of the invention to provide a kind of headlamp starting mentioned type, the assembling making its all parts wherein is easy.

Headlamp for the type mentioned by beginning, this purpose thus realizes, i.e. housing is formed as with at least one for the central housing of the central receiving portion (Zentralaufnahme) of immobilising device, i.e. being provided with the receiving framework for accommodating at least one electronic storage unit and lighting unit and receiving framework has at least one annular fishplate bar (Ringlasche) accordingly, it can releasably be connected with central housing by means of the immobilising device that can introduce in central authorities' receiving portion.

This advantage is associated with this, i.e. lighting unit and the framework that accommodates for memory element utilizes at least one common immobilising device (such as bolt) to can determine that at housing.Therefore, mutual this of component determines and fixes the light effect providing the accurate of headlamp and reproducing.

When central authorities receiving portion, immobilising device and annular fishplate bar the most double arrange time, it was demonstrated that for particularly advantageous.Therefore, in addition to the power clampingly produced from immobilising device, the rotary freedom around immobilising device longitudinal axis is hindered by the form fit on double the annular fishplate bar arranged with being attached.Additionally, the component of headlamp thus can the most highly precisely be orientated.

When housing has housing support (Gehaeusestuetze), it is especially interesting.This housing supports the heat produced by LED from the heat sensitive electronic storage unit shielding accommodated framework, and wherein, it facilitates the stability that headlamp is additional.

When housing support have at least one, preferably exactly two breakthrough part (Durchfuehrung) time, be favourable.In these breakthrough parts, the annular fishplate bar accommodating framework and lighting unit can insert and be assembled in central authorities' housing with being directed to.

It is shown as it is particularly preferred that central authorities' receiving portion has the composition surface for disposing at least one annular fishplate bar.This composition surface also provides simplicity during assembling for assembler, because it obtains the prompting to this by composition surface, i.e. which position lighting unit and receiving framework must be taken in by it, in order to determined at housing by two components.

Additionally, when annular fishplate bar is designed to mutually recline, be favourable.In addition to flat composition surface, wave or jagged composition surface is possible, the annular fishplate bar of its annular fishplate bar stoping lighting unit and receiving framework relative motion to each other.

When accommodating framework and there is the element that the position after it is fixed, it was demonstrated that for particularly advantageous.Often, electronic storage unit weighs very much so that the annular fishplate bar determined with immobilising device accommodating framework suffers the strongest load.Here, element is fixing to balance these loads for accommodating framework position below.By can provide the simple probability realizing the element fixing with position later by means of the annular fishplate bar that immobilising device is fixing.

When accommodate framework by can modular replacing in the way of formed time, it was demonstrated that for particularly advantageous.Thus, different receiving frameworks can be used in headlamp for accommodating different electronic storage unit.In particular, memory element such as lithium-ions battery, ni-au genus-hydride accumulator or common battery or standard storage battery can be according to finding in the headlamp of the present invention that it is applied.

Finally turn out to be advantageously, accommodate framework be associated with at least one can modular change and the contact element that can releasably be connected with circuit board.Thus, different battery types or battery size can be used for the operation of headlamp.

It is embodied as form

Fig. 1 to 5 shows for two wheeler, the headlamp 1 that is particularly useful for bicycle, electric bicycle, electric motor car etc., and it, with housing 2, is provided with the circuit board 4 controlling LED 3 wherein；With accommodating the lighting unit 5 of LED, its have in the case of making full use of reflector 6 and diffusing glass 7 with road traffic or emission characteristics that the requirement of legal provisions matches.Housing 2 is formed with the central housing 2 of two central receiving portions 8 for two immobilising devices 9 in the illustrated embodiment.Receiving framework 10 is provided for accommodating electronic storage unit 11 and lighting unit 5 and accommodating framework 10 have exactly two annular fishplate bar 12 accordingly, and it can releasably be connected with central housing 2 by means of the immobilising device 9 that can introduce in central authorities' receiving portion 8.

Central authorities' housing 2 has housing and supports 13, is configured with two breakthrough parts 14 for pessum fishplate bar 12 wherein.Here, each central authorities receiving portion 8 has the composition surface 15 for disposing annular fishplate bar 12.

In fig. 2, the annular fishplate bar 12 of lighting unit 5 contacts with the composition surface 15 of central receiving portion 8.In addition illustrate that electronic storage unit 11 is installed to accommodate in framework 10.The shown framework 10 that accommodates has the element 16 fixing for position behind, and it is formed as the fixing annular fishplate bar 12 of available immobilising device 9 at this.

May recognize that in figure 3, annular fishplate bar 12 is designed to mutually recline in shown embodiment.Additionally, be provided with the support 19 for swingable cover plate 18 in housing supports 13.In cover plate 18, there is foamed materials 20 location, and its (as shown in FIG. 4) is used as the pad (Polsterung) between cover plate 18 and electronic storage unit 11.The most in addition may recognize that, at central authorities' housing 2, be provided with the button 21 for operating circuit board 4.The spring 22 of supporting crank 23 it is disposed with at cover plate 18.Thus, headlamp 1 can be releasably connected with support.

In Figure 5, electronic storage unit 11 is disassembled and illustrates the headlamp 1 with the cover plate 18 opened.
