Description

摩托车前照灯散热结构Motorcycle headlamp cooling structure

技术领域technical field

本发明涉及一种摩托车LED前照灯。特别涉及一种摩托车前照灯散热结构。The invention relates to a motorcycle LED headlamp. In particular, it relates to a cooling structure for motorcycle headlights.

背景技术Background technique

现有的摩托车中，为了方便夜晚行驶，在车头会设置前照灯，并且安装标准要求，前照灯需要具有远光功能和近光功能。In existing motorcycles, in order to facilitate driving at night, headlights are provided on the front of the car, and the installation standard requires that the headlights need to have a high-beam function and a low-beam function.

现有的摩托车中采用的前照灯，结构普遍为包括一个灯壳，灯壳前端设置透镜，灯壳内部设置由灯珠和反光碗等构件组成的照明结构。其中，透镜设置时，一般是将灯壳前段部分采用二次成形的方式和透镜成形为一体；然后再将灯壳前段部分和主体部分相连，这样，虽然透镜位置防水效果较好，不会进水，但透镜安装不便，同时灯壳前段部分和主体部分连接处不具有防水效果，导致雨天行驶时，雨水容易进入到灯壳内部，造成电路短路。The headlights used in existing motorcycles generally have a structure including a lamp housing, a lens is arranged at the front end of the lamp housing, and an illumination structure composed of lamp beads and reflective bowls is arranged inside the lamp housing. Among them, when the lens is installed, the front part of the lamp housing is generally formed into one body with the lens by secondary forming; Water, but the installation of the lens is inconvenient, and at the same time, the connection between the front part of the lamp housing and the main part is not waterproof, so that when driving in rainy days, rainwater easily enters the inside of the lamp housing, causing a short circuit.

另外，现有的摩托车前照灯中，照明结构，一般由两套独立的灯珠和反光碗完成远光功能和近光功能，其体积较大，占用空间较大，同时一般会采用电磁铁变光机构来转换远/近光，使得前照灯发热量大，同时现有的前照灯没有专门的散热结构，散热效果较差，造成照明结构长期处于较高温度状态，使得LED产生光衰现象，进而极大地影响了LED照明效果以及使用寿命。In addition, in the existing motorcycle headlights, the lighting structure generally consists of two sets of independent lamp beads and reflective bowls to complete the high beam function and the low beam function. The iron dimming mechanism is used to convert the far/low beam, which makes the headlight generate a lot of heat. At the same time, the existing headlight does not have a special heat dissipation structure, and the heat dissipation effect is poor, causing the lighting structure to be in a high temperature state for a long time, causing the LED to produce The phenomenon of light decay, which in turn greatly affects the LED lighting effect and service life.

The heat dissipation back cover and the mounting seat are both made of aluminum. The mounting brackets formed by the front extensions are in contact.

本发明的散热结构，灯珠和电路板散发的热量更容易通过安装座导出到散热后盖，散热后盖外表面和流通空气接触，散热效果好，缓解了照明结构由于过热造成的光衰现象，延长了照明结构使用寿命。With the heat dissipation structure of the present invention, the heat emitted by the lamp beads and the circuit board is more easily exported to the heat dissipation back cover through the mounting seat, and the outer surface of the heat dissipation back cover is in contact with the circulating air, the heat dissipation effect is good, and the light decay phenomenon caused by overheating of the lighting structure is alleviated , prolong the service life of the lighting structure.

This has the effect of simple and quick assembly and good sealing effect.

其中，所述安装平面上还设置有一圈安装槽并安装有一个环形的位置灯光带6，位置灯光带6外表面被透镜2底面压紧固定。这样本前照灯进一步具有了位置灯光显示的功能，同时灯光带的装配非常方便快捷。具体实施时，位置灯光带6的安装槽的两侧面呈和位置灯光带外表匹配的弧形，以更加利于位置灯光带的安装稳定。Wherein, the installation plane is also provided with a ring of installation grooves and an annular position light strip 6 is installed, the outer surface of the position light strip 6 is pressed and fixed by the bottom surface of the lens 2 . In this way, the headlight further has the function of position light display, and at the same time, the assembly of the light strip is very convenient and fast. During specific implementation, the two sides of the installation groove of the position lighting strip 6 are in an arc shape matching the appearance of the position lighting strip, so as to be more conducive to the installation stability of the position lighting strip.

其中，所述照明结构，包括一个用于安装LED灯珠的安装座7，安装座7包括一个整体呈圆盘旋转的座体，座体内设置有电路板8，座体前端中部具有一个向前延伸形成的安装凸起9，安装凸起9一侧具有一个大L形的远光灯安装面，远光灯安装面的竖向平面上安装有远光用反光半碗10，远光灯安装面的横向平面上对应远光用反光半碗聚焦点位置安装有远光用LED灯珠11，安装凸起9另一侧具有一个小L形的近光灯安装面，近光灯安装面的竖向平面上安装有近光用反光半碗12，近光灯安装面的横向平面上对应近光用反光半碗聚焦点位置安装有近光用LED灯珠13。Wherein, the lighting structure includes a mounting seat 7 for installing LED lamp beads.

这样，设计了巧妙的照明结构使得远近光功能合二为一，和现有技术相比，结构更加简单，节省了成本且极大地节省了构件占用空间，使得灯壳内部空间较大，更加利于散热。In this way, an ingenious lighting structure is designed to combine the far and near light functions into one. Compared with the existing technology, the structure is simpler, the cost is saved and the space occupied by the components is greatly saved, so that the internal space of the lamp housing is larger, which is more conducive to Heat dissipation.

其中，所述灯壳1内腔后端向前延伸形成有安装架14，所述安装座7位于安装支架14内部，安装座7通过座体周边向前延伸的连接条连接有一个环形的安装圈15，并靠安装圈15安装连接在所述安装架14上。这样，更加方便照明结构的安装和散热。Wherein, the rear end of the inner cavity of the lamp housing 1 extends forward to form a mounting frame 14, the mounting seat 7 is located inside the mounting frame 14, and the mounting seat 7 is connected to a ring-shaped mounting bracket through a connecting strip extending forward from the periphery of the seat body.

这样，散热片的设置，等于延展了安装座的表面积，提高了和空气的接触散热效果以及和散热后盖的接触散热效果，进一步提高了散热效率。In this way, the arrangement of the heat sink is equivalent to extending the surface area of the mounting seat, improving the contact heat dissipation effect with the air and the contact heat dissipation effect with the heat dissipation back cover, and further improving the heat dissipation efficiency.

其中，所述散热后盖17前端边沿插入到灯壳主体后端的一圈插接槽内再靠热熔胶形成密封连接。这样，具有连接方便快捷且密封效果好的优点。Wherein, the front edge of the heat dissipation back cover 17 is inserted into a circle of insertion grooves at the rear end of the lamp housing body, and then sealed and connected by hot melt adhesive. In this way, it has the advantages of convenient and fast connection and good sealing effect.
