Description

Technical Field

[0001] This utility model relates to the field of vehicle lighting technology, and in particular to a vehicle lighting lamp and a vehicle lighting heat dissipation device. Background Technology

[0002] Vehicle lights are an important component of a vehicle, mainly composed of a lamp housing, lamp beads, light-transmitting plate, heat-conducting column, radiator, etc. They serve the functions of illumination and signaling, and can improve driving safety at night and in adverse weather conditions.

[0003] Some existing vehicle headlight designs incorporate radiators and cooling fans to achieve effective heat dissipation. The radiator first absorbs the heat generated by the LED chips, and then the cooling fan guides airflow to contact the radiator surface, carrying away the heat. However, in this heat dissipation method, since the airflow blows directly onto the radiator, some of the airflow, while carrying away heat, diffuses outwards without direction. This diffusion not only reduces the heat exchange efficiency between the airflow and the radiator but also weakens the radiator's heat dissipation effect. Therefore, a vehicle headlight and a vehicle headlight heat dissipation device are proposed. Utility Model Content

[0004] The purpose of this invention is to provide a vehicle lamp and a vehicle lamp heat dissipation device, which can solve the problem that when the airflow blows directly onto the radiator, some of the airflow carries away heat and diffuses directly to the outside without direction. This diffusion phenomenon not only reduces the heat exchange efficiency between the airflow and the radiator, but also easily leads to a weakening of the radiator's heat dissipation effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle headlight heat dissipation device, comprising a radiator body, and further comprising:

[0006] A connecting plate is disposed on the outer surface of the radiator body;

[0007] A heat dissipation mechanism is disposed on the outer surface of the connecting plate and is fixedly connected to the heat sink body;

[0008] An impeller mechanism is provided on one side of the connecting plate and is fixedly connected to the heat dissipation mechanism.

[0009] Preferably, the heat dissipation mechanism includes a heat dissipation fan disposed on the outer surface of the connecting plate, a housing disposed on one side of the heat dissipation fan, the housing being rotatably connected to the connecting plate, a support plate being rotatably connected to the outer surface of the housing away from the connecting plate, the support plate being fixedly connected to the heat sink body, and an air outlet hole being provided on the outer surface of the housing.

[0010] Preferably, the housing and the connecting plate are rotatably connected by a bearing, and the housing and the support plate are rotatably connected by a bearing.

[0011] Preferably, the number of air outlets is multiple, and they are arranged in a circular array.

[0012] Preferably, the impeller mechanism includes a connecting rod disposed on one side of the connecting plate, the connecting rod being fixedly connected to the inner wall of the housing, and the outer surface of the connecting rod being provided with fan blades.

[0013] Preferably, the housing, support plate, and connecting rod are all made of polypropylene plastic.

[0014] This utility model also provides a vehicle lamp, including a heat-conducting plate, a lamp bead body and the above-mentioned vehicle lamp heat dissipation device, wherein the heat-conducting plate is disposed on the outer surface of the radiator body and the lamp bead body is disposed on the outer surface of the heat-conducting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. This application achieves efficient heat dissipation of the vehicle headlight during operation through the design of a heat dissipation mechanism and an impeller mechanism. Specifically, when the headlight is working, the heat generated by the lamp body is effectively conducted to the radiator body through the heat conduction plate. Subsequently, the cooling fan is activated, and external airflow is drawn into the housing. After the airflow comes into contact with the fan blades, it drives the fan blades and their connected connecting rods to rotate, thereby driving the entire housing to rotate. The airflow entering the housing is effectively guided and discharged when it passes through the air outlet on the rotating housing. In this process, the airflow flows from the inside to the outside, carrying away the heat on the radiator body and effectively avoiding the problem of some airflow directly diffusing to the outside. This significantly improves the heat exchange efficiency between the airflow and the radiator body, thereby enhancing the heat dissipation effect of the radiator body. Attached Figure Description

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 4 This utility model provides a technical solution:

[0026] A vehicle headlight heat dissipation device includes a radiator body 1, and further includes:

[0027] Connecting plate 8 is disposed on the outer surface of radiator body 1;

[0028] Heat dissipation mechanism 2 is disposed on the outer surface of the connecting plate 8 and is fixedly connected to the heat sink body 1;

[0029] Impeller mechanism 3 is located on one side of connecting plate 8 and is fixedly connected to heat dissipation mechanism 2.

[0030] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the heat dissipation mechanism 2 includes a heat dissipation fan 21 disposed on the outer surface of the connecting plate 8. A housing 22 is disposed on one side of the heat dissipation fan 21. The housing 22 is rotatably connected to the connecting plate 8. A support plate 23 is rotatably connected to the outer surface of the housing 22 away from the connecting plate 8. The support plate 23 is fixedly connected to the heat sink body 1. An air outlet 24 is provided on the outer surface of the housing 22.

[0031] Specifically, such as Figure 2 and Figure 3As shown, the housing 22 is rotatably connected to the connecting plate 8 via bearing 4, and the housing 22 is rotatably connected to the support plate 23 via bearing 5. This reduces the rotational friction of the housing 22, thereby facilitating the rotation of the housing 22.

[0032] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, there are multiple air outlets 24 arranged in a circular array, which ensures that the air flows evenly in multiple directions, thereby improving the uniformity and stability of the airflow.

[0033] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the impeller mechanism 3 includes a connecting rod 31 disposed on one side of the connecting plate 8. The connecting rod 31 is fixedly connected to the inner wall of the housing 22, and the outer surface of the connecting rod 31 is provided with fan blades 32.

[0034] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the shell 22, support plate 23 and connecting rod 31 are all made of polypropylene plastic, which has the characteristics of high temperature resistance, high hardness, light weight and corrosion resistance.

[0035] Specifically, such as Figure 1 and Figure 2 As shown, this utility model also provides a vehicle lamp, including a heat-conducting plate 6, a lamp bead body 7 and the above-mentioned vehicle lamp heat dissipation device. The heat-conducting plate 6 is disposed on the outer surface of the radiator body 1, and the lamp bead body 7 is disposed on the outer surface of the heat-conducting plate 6.

[0036] Working principle: When the headlight is working, the lamp body 7 emits light and generates heat. This heat is conducted to the radiator body 1 through the heat conduction plate 6. Then the cooling fan 21 is activated, and external airflow is drawn into the housing 22. After the airflow comes into contact with the fan blade 32, it drives the fan blade 32 and the connecting rod 31 connected to it to rotate, which in turn drives the entire housing 22 to rotate. The airflow entering the housing 22 is effectively guided and discharged when it passes through the air outlet 24 on the rotating housing 22. In this process, the airflow flows from the inside to the outside, taking away the heat from the radiator body 1, thereby achieving efficient heat dissipation.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
