Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle lamps, and in particular relates to a vehicle lamp with an active heat dissipation device. Background Art

[0002] In the prior art, in order to realize various new functions of lamps such as ADB, MDF or DLP, the working power of the module light source in the lamp is greatly improved, which makes the internal heat of the lamp increase sharply, and the existing passive heat dissipation method can no longer meet the use requirements of the lamp; in order to meet the heat requirements, the prior art often adopts a method in which the cooling fan is fixed to the rear side of the lamp through a bracket, and blows air forward along the rear direction. With the development of the times and in response to the requirements of national laws and regulations, the illumination angle of the lamp module light source needs to be adjusted up, down, left and right, and it is required to maintain good heat dissipation when the illumination angle of the module light source changes. When the angle of the module light source is adjusted, since the fan is fixed on the shell, the cooling fan cannot completely blow to the module light source, affecting the heat dissipation of the module light source, which should affect the optical performance. Utility Model Content

[0003] The purpose of the utility model is to provide a vehicle lamp with an active heat dissipation device to solve the technical problem that the module light source and the cooling fan cannot be adjusted at the same time and always maintain good heat dissipation, so as to achieve the purpose of maintaining good heat dissipation when the module light source irradiation angle is adjusted.

[0004] In order to solve the above technical problems, the utility model provides a vehicle lamp with an active heat dissipation device, comprising:

[0005] A bracket, wherein a first module light source and a second module light source are arranged on the bracket, a straight line on the bracket is defined as a first straight line, and the first module light source and the second module light source are arranged along the first straight line;

[0006] A rotating shaft, the rotating shaft is arranged on the bracket, and the axis of the rotating shaft is perpendicular to the first straight line;

[0007] A cooling fan is detachably mounted on the bracket and is located on a side of the second module light source away from the first module light source. The cooling fan is arranged along the first straight line.

[0008] Furthermore, the bracket includes a bracket inner frame arranged around the outside of the first module light source and the second module light source and a bracket outer frame arranged around the outside of the two bracket inner frames, and the two bracket inner frames and the bracket outer frame are fixedly connected.

[0009] Furthermore, the bracket inner frame is fixedly connected to the outer sides of the first module light source and the second module light source, and a plurality of cross-arranged reinforcing ribs are provided between the bracket inner frame and the bracket outer frame, and between the two bracket inner frames.

[0010] Furthermore, the bracket is located on a side of the second module light source away from the first module light source, and extends forward to form an annular mounting portion, and the cooling fan is detachably mounted in the annular mounting portion by screws.

[0011] Furthermore, a first propulsion member is provided between the inner frame of the support and the outer frame of the support, and the first propulsion member is located at a position far away from the rotating axis.

[0012] Furthermore, a second propulsion member is provided between the inner frame of the bracket and the outer frame of the bracket, and the second propulsion member is located close to the rotating shaft.

[0013] The beneficial effects of the utility model are:

[0014] 1. The first module light source, the second module light source and the cooling fan are fixed on the bracket at the same time, and the above three are always distributed along the same straight line, so that when the bracket is tilted, the cooling fan can still efficiently dissipate heat for the first module light source and the second module light source in the same direction.

[0015] 2. By arranging reinforcing ribs on the bracket, the gaps between the cross structures of the reinforcing ribs are hollow structures, which ensures the strength of the bracket while reducing the weight and materials of the bracket, while reducing the production cost.

Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. 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.

[0024] Example:

[0025] like Figures 1 to 3 As shown, a vehicle lamp with an active heat dissipation device comprises: a bracket 1, on which a first module light source 2 and a second module light source 3 are provided, a straight line on the bracket 1 is defined as a first straight line, and the first module light source 2 and the second module light source 3 are arranged along the first straight line; a rotating shaft 4, which is provided on the bracket 1, and the axis of the rotating shaft 4 is perpendicular to the first straight line; a cooling fan 5, which is detachably provided on the bracket 1 and is located on a side of the second module light source 3 away from the first module light source 2, and the cooling fan 5 is arranged along the first straight line.

[0026] It should be noted that: the first module light source 2 is a 100-pixel ADB module, which can realize the ADB function and the anti-glare high beam function, the second module light source 3 is a high and low beam module, which can realize the high and low beam function, the first module light source 2 and the second module light source 3 are fixedly arranged on the bracket 1 along the first straight line, and the bracket 1 can rotate around the rotation axis 4, and drive the first module light source 2 and the second module light source 3 to rotate around the rotation axis 4 to realize the adjustment of the irradiation angle of the first module light source 2 and the second module light source 3; the cooling fan 5 is detachably arranged on the side of the second module light source 3 away from the first module light source 2, to ensure that the wind blown by the cooling fan 5 passes through the first module light source 2 and the second module light source 3 respectively. The first module light source 2 and the second module light source 3 are used to dissipate heat, and at the same time, the first module light source 2, the second module light source 3 and the cooling fan 5 are simultaneously arranged at fixed positions on the bracket 1. When the bracket 1 is deflected around the rotation axis, the first module light source 2, the second module light source 3 and the cooling fan 5 will also be deflected at the same time, and the first module light source 2, the second module light source 3 and the cooling fan 5 are always kept distributed along the first straight line, so as to ensure that when the bracket 1 is tilted, the cooling fan 5 can still efficiently dissipate heat in the same direction for the first module light source 2 and the second module light source 3.

[0027] Specifically, the bracket 1 includes a bracket inner frame 6 disposed around the outside of the first module light source 2 and the second module light source 3 and a bracket outer frame 7 disposed around the outside of the two bracket inner frames 6.

[0029] It should be noted that: cross-arranged reinforcing ribs 8 are provided between the two bracket inner frames 6, and between the two bracket inner frames 6 and the bracket outer frame 7, and there is a hollow structure between the cross-arranged reinforcing ribs 8. The reinforcing ribs 8 can well ensure the connection strength between the two bracket inner frames 6, and between the two bracket inner frames 6 and the bracket outer frame 8 through crossing, and the hollow setting method greatly saves the materials used in the manufacture of the bracket 1 and reduces the production cost while ensuring the strength of the bracket 1. At the same time, it also reduces the overall weight of the bracket 1, making it easier to drive the bracket 1 to rotate.

[0030] Preferably, the bracket 1 is located on a side of the second module light source 3 away from the first module light source 2 , and extends forward to form an annular mounting portion 9 , and the cooling fan 5 is detachably mounted in the annular mounting portion by screws 10 .

On the other hand, the four corners of the cooling fan 5 are fixed to the four corners inside the annular mounting portion by four screws 10, thereby ensuring the stability of the installation of the cooling fan 5.

[0032] Preferably, a first propulsion member 11 is further provided between the bracket inner frame 6 and the bracket outer frame 7. The first propulsion member 11 is a push rod motor. The first propulsion member 11 is located away from the rotating axis 4 and pushes the bracket 1 to rotate around the rotating axis 4 to adjust the irradiation direction of the first module light source 2 and the second module light source 3.

[0033] Preferably, a second propulsion member 12 is further provided between the bracket inner frame 6 and the bracket outer frame 7 .
