Description

Technical Field

[0001] The utility model relates to the technical field of vehicle lamps, in particular to a combined vehicle lamp and a vehicle with integrated rear fog lamp and reverse lamp functions. Background Art

[0002] Reversing lights and rear fog lights are usually installed at the rear of the vehicle. Regulations require that each vehicle must be equipped with 1-2 reversing lights and rear fog lights. When the number of installations is 1, it is usually located on the left or right side of the rear of the vehicle (the rear fog light can only be installed in the center or on the driver's side); when the number of installations is 2, they are usually symmetrically distributed on the left and right sides of the rear of the vehicle. In the first case, since it is installed on one side of the vehicle body, the other side cannot be lit. This installation method has little impact on the rear fog light, but has a greater impact on the reversing light, resulting in a smaller illuminated area behind the vehicle when reversing and uneven brightness, which poses certain safety hazards. In the second case, the large number of lights leads to increased costs and will also take up more space at the rear of the vehicle. Utility Model Content

[0003] The main purpose of the utility model is to solve the problems of poor lighting effect of existing reversing lights and rear fog lights installed on one side and high cost of bilateral symmetrical installation, and to provide a combined rear light installed in the center of the rear of the vehicle. The lamp not only has a good lighting effect, but also has a small size, low cost, good heat dissipation, and improved reliability and service life. To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0004] A combined vehicle lamp with integrated rear fog lamp and reverse lamp functions, comprising a light distribution mirror 1, a lamp housing 2, a wiring harness assembly 4, and an LED module 5. The LED module 5 is fixed on the lamp housing 2, the light distribution mirror 1 is fixedly connected to the lamp housing 2, and the LED module 5 is encapsulated therebetween; the wiring harness assembly 4 is fixed on the lamp housing 2 and connected to the LED module 5. The rear fog lamp and reverse lamp are dispersedly arranged on the front of the LED module 5, and the rear fog lamp and reverse lamp light up after power is turned on, respectively realizing the corresponding vehicle lamp functions.

[0005] Furthermore, the LED module 5 is provided with two groups of rear fog lights 7 and two groups of reversing lights 8 . The two groups of rear fog lights 7 are located in the middle of the LED module 5 and are spaced a certain distance apart from each other. The other two groups of reversing lights 8 are respectively arranged on the outside of the two rear fog lights 7 , one on the left and one on the right.

[0006] Furthermore, the two groups of rear fog lights 7 and the two groups of reversing lights 8 are located on the same horizontal line and face the middle position of the light distribution mirror 1 .

[0007] Furthermore, a rear fog lamp condenser is provided at a position corresponding to each rear fog lamp 7 on the light distribution mirror 1, and the root of the rear fog lamp condenser is located in a groove on the inner surface of the light distribution mirror 1. One end of the rear fog lamp condenser is designed to be convex, and the other end is designed to be sunken, so that a better focusing effect can be achieved, and interference and influence on the reversing lamp can be avoided, and at the same time, the light emitted by the rear fog lamp can be scattered in different directions as much as possible to obtain a better lighting effect.

[0008] Furthermore, the rear fog lamp condenser is approximately in the shape of a crater, and the two rear fog lamp condensers are located in the same groove on the inner surface of the light distribution mirror 1.

[0009] Furthermore, a reversing light concentrator is provided at a position corresponding to each reversing light 8 on the light distribution mirror 1 , and the reversing light concentrator is approximately W-shaped.

During assembly, glue is first applied to the U-shaped groove 10, and then the T-shaped clamping column is inserted into the U-shaped groove 10, and finally the photometric lens and the lamp housing are fastened with screws, which plays a double insurance role.

[0012] Furthermore, the light distribution mirror 1 and the LED module 5 are both in the shape of thin strips. The thin strip-shaped LED module 5 is more conducive to the dispersed arrangement of the rear fog lamp and the reversing lamp along its length direction, which can avoid the mutual influence between the rear fog lamp and the reversing lamp due to the close distance, and at the same time take into account the lighting effect and the illumination range of the reversing lamp.

[0020] In order to enable ordinary technicians in the field to fully understand the technical solutions and beneficial effects of the utility model, further description is given below in conjunction with specific embodiments and drawings.

[0021] The utility model provides a Figure 1-4 The combination lamp shown is used to realize the functions of rear fog lamp and reverse lamp. The lamp is very small, with an appearance of only 58mm*154mm*57mm, and a horizontally arranged rectangle on the front. The light outlet of the lamp is located in the middle of the front of the lamp, and the shape is a slender rectangle with a width of only 6.3mm, which is just enough to arrange the minimum size ECE logo required by regulations. At present, the lamp is expected to become the smallest combination rear lamp in China that includes rear fog lamp and reverse lamp functions.

[0022] The combined vehicle lamp mainly includes a light distribution mirror 1, a lamp housing 2, a rubber plug 3, a wiring harness assembly 4, an LED module 5, and a screw 6, wherein the lamp housing 2 is the assembly body, and the other parts are directly or indirectly fixed on the lamp housing 2. Specifically, the light distribution mirror 1 is a colorless transparent plastic injection molded part, with a light outlet provided on its upper surface, a T-shaped clamping column provided around four edges on its lower surface, and screw holes provided on its left and right ends. The lamp housing 2 is an aluminum alloy precision casting, and the LED module 5 is fixed on the lamp housing 2 by a positioning pin or a buckle, and the T-shaped clamping column at the bottom of the light distribution mirror 1 is inserted into the U-shaped groove 10 on the lamp housing 2. In order to ensure the reliability and sealing effect of the connection, silicone is coated on the surface of the T-shaped clamping column in advance, and the light distribution mirror and the lamp housing are fixed again by screws 6, thereby realizing the encapsulation of the lamp. The assembled lamp is plugged with a rubber plug 3 at the position of the airtight detection hole. The wiring harness assembly 4 is plugged into the lamp housing 2, one end of which is connected to the LED lamp bead on the LED module 5, and the other end is connected to the vehicle power supply or circuit.

[0023] The LED module 5 of the combined headlight is also in the shape of a strip, and four groups of LED light sources are arranged on its outer surface, of which the middle two groups are rear fog lights 7, and the outer two groups are reversing lights 8. The rear fog lights 7 use red light LEDs, and the reversing lights 8 use white light LEDs. As a matching device, corresponding condensers are arranged at each light source (i.e., at the light outlet position) on the inner surface of the light distribution mirror 1. Figure 3 As shown in the circles in the figure above, the inventors have previously tried to set the condensers corresponding to the rear fog lamp 7 and the reverse lamp 8 to be flat and convex, but experiments have found that this will cause interference between the functions of the two lamps. For this reason, the inventors have made adjustments and set the condensers corresponding to the rear fog lamp 7 and the reverse lamp 8 to be sunken (the condensers extend outward from the groove) and flat W-shaped (such as Figure 3 As shown in the figure below, the rear fog lamp 7 and the reversing lamp 8 are independent of each other, do not interfere with each other, and have a better lighting effect. Considering that the heat generated by the four groups of LEDs when working is large and easily gathered in the well-sealed lamp cavity, a metal material is selected to form the lamp housing 2, and it is closely attached to the LED module 5 during assembly for heat dissipation. In addition, multiple groups of parallel heat dissipation structures 9 are arranged on the bottom surface of the lamp housing 2 to further improve the heat dissipation effect.

[0024] The structure of the combination headlight is relatively compact, and it has the advantages of low cost and simple assembly. Only one is required on each vehicle, and it is centrally installed on the central axis of the rear of the vehicle, thereby achieving a larger illumination range and a more uniform lighting effect with the least number of lamps.
