[0049] Hereinafter, embodiments will be described with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the utility model content described in the claims in any way. Further, all the contents of the configurations shown in the following embodiments are not limited to those necessary for the solution of the utility model described in the claims. It should be noted that for ease of description, only parts related to the utility model are shown in the drawings. Without conflict, the embodiments and features in the embodiments of the present utility model can be combined with each other.
[0050] Combined with Figures 1-4 , the heat dissipation assembly disclosed in the embodiment of the present utility model includes a heat dissipation fan 100 and a heat dissipation duct 200. The heat dissipation fan 100 has a fan air outlet for air outlet; there is at least one heat dissipation duct 200, and the heat dissipation duct 200 is a flexible duct that can be freely bent, and has a duct air inlet and a duct air outlet. The duct air inlet is communicated with the fan air outlet, and the duct air outlet is used to face the heat generating components 500 such as the light emitting unit and the light dimming module in the vehicle lamp, and is fixed to the heat generating components 500.
[0051] When the heat dissipation fan 100 is started, the heat dissipation air flow sequentially passes through the fan air outlet and the duct air inlet, and finally blows to the heat generating components 500 from the duct air outlet for heat dissipation. And since the heat dissipation duct 200 is a flexible duct, it can adapt to move synchronously with the heat generating components 500 within a certain range.
[0052] Compared with the prior art, through the setting of the heat dissipation duct 200, the present utility model can directly direct the heat dissipation air flow blown out by the heat dissipation fan 100 to the heat generating components 500, with more accurate heat dissipation and better effect. And the flexible material setting of the heat dissipation duct 200 enables it to bend freely within a certain range, facilitating flexible layout according to the actual situation in the vehicle lamp, with strong applicability. At the same time, the heat dissipation duct 200 can also move together with the movement of the heat generating components 500 (for example, the light dimming module) to ensure accurate heat dissipation effect.
[0053] Among them, the cross-sectional shape of the flexible duct can specifically be circular, square, oval, etc., and the present utility model does not limit this.
[0054] According to the actual quantity and position of the heat generating components 500 in the vehicle lamp, there are usually multiple heat dissipation ducts 200, and each heat dissipation duct 200 is communicated with the fan air outlet through an air flow diffusion component 300, so as to be able to direct the heat dissipation air flow to the positions where the respective heat generating components 500 in the vehicle lamp are located. Through a single heat dissipation fan 100, different heat generating components 500 can be accurately cooled simultaneously, effectively reducing the number of heat dissipation fans 100 and lowering the heat dissipation cost.
[0055] Specifically, combined with Figure 5 、 Figure 6 and Figure 7, a fan connection port 301 is provided at the first end of the air flow diffusion component 300, and a plurality of pipe connection ports 302 are provided at the second end. The fan connection port 301 and the pipe connection ports 302 are in communication, and the pipe connection ports 302 are in one-to-one correspondence and communication with the pipe air inlets of the respective heat dissipation pipes 200. The fan connection port 301 is in communication with the fan air outlet.
[0056] The above-mentioned air flow diffusion component 300 is a hollow component and can be prepared from PET (Polyethylene Terephthalate). To ensure airtightness, the air flow diffusion component 300 is hermetically connected to the heat dissipation fan 100 and the heat dissipation pipes 200 by means of gluing. In addition, hermetic connection can also be achieved by setting a gasket and pressing it tightly.
[0057] Heat dissipation fins for heat dissipation are usually provided on the back of the heat generating component 500. Since the cross-sectional size of the pipe air outlet is usually smaller than the size of the heat dissipation fins, in order to evenly direct the heat dissipation air flow blown out by the heat dissipation pipe 200 to the heat generating component 500 and at the same time fix the pipe air outlet of the heat dissipation pipe 200 to the heat generating component 500, combined with Figure 8 and Figure 9 , a wind guiding component 400 is provided at the pipe air outlet. The wind guiding component 400 is connected between the pipe air outlet and the heat generating component 500. A wind guiding outlet 401 is through-opened on the wind guiding component 400, and the first end of the wind guiding outlet 401 is in communication with the pipe air outlet, and the second end is used to face the heat generating component 500 and is fixed to the heat generating component 500 (exemplarily, fixed to the dimming bracket of the dimming module), and along the direction from the first end to the second end of the wind guiding outlet 401, the cross-sectional area of the wind guiding outlet 401 gradually increases to direct the heat dissipation air flow to more positions of the heat dissipation fins to achieve sufficient heat exchange.
[0058] The pipe air outlet of the heat dissipation pipe 200 or the wind guiding component 400 can be specifically directly connected to the heat generating component 500. In order for the heat dissipation pipe 200 to avoid other components in the vehicle lamp, the heat dissipation assembly further includes a support member 600. The support member 600 is connected to the heat dissipation pipe 200, can provide a certain supporting force to the heat dissipation pipe 200, and shape the bending shape of the heat dissipation pipe 200 in the vehicle lamp.
[0059] Specifically, when the support member 600 is a flexible support rod, combined with Figure 3, the extended length of the flexible support rod is less than that of the heat dissipation duct 200. The flexible support rod is attached to the outer wall of the heat dissipation duct 200 along the extending direction of the heat dissipation duct 200, and one end of it extends to the duct air inlet of the heat dissipation duct 200, while the other end is spaced from the duct air outlet of the heat dissipation duct 200 by a preset distance. By bending the flexible support rod, the end of the heat dissipation duct 200 near the duct air inlet can be fixed in a certain bent shape, avoiding affecting other structures inside the headlight. The end of the heat dissipation duct 200 near the duct air outlet is not fixed by the flexible support rod and can move adaptively and bend within a certain range following the movement of the heat generating component 500.
[0060] When the support member 600 is a rigid telescopic rod, one end of the support member 600 is connected to the heat dissipation duct 200, and the other end is used to connect to the housing of the headlight. The rigid telescopic rod can adjust the telescopic length according to the actual situation inside the headlight, and then drive the heat dissipation duct 200 to change its bent shape to avoid other structures inside the headlight. It can be understood that the rigid telescopic rod can support the heat dissipation duct 200 at the bottom of the heat dissipation duct 200, or support the heat dissipation duct 200 obliquely, or as Figure 4 shown, hang the heat dissipation duct 200 at several points from the top to realize the adjustment of the bent shape of the heat dissipation duct 200.
[0061] The above support member 600 can be specifically connected to the heat dissipation duct 200 through components such as cable ties.
[0062] Combined with Figures 10-13 , the headlight disclosed in the embodiment of the present utility model includes a lamp housing, a heat generating component 500 and the above heat dissipation assembly. The heat generating component 500 and the heat dissipation assembly are both arranged inside the lamp housing, and the duct air outlet faces the heat generating component 500 and is connected to the heat generating component 500. Due to having the above heat dissipation assembly, it also has the above structure and beneficial effects. Other structures refer to the prior art and will not be elaborated here.
[0063] Among them, the heat dissipation duct 200 can be specifically fixed on the lamp housing through buckles, or a bracket is arranged inside the lamp housing, and the heat dissipation duct 200 is fixed on the bracket through buckles.
[0064] Specifically, in one embodiment, the heat generating component 500 is a dimming module, the duct air outlet faces the heat dissipation fins of the dimming module, and is fixed to the dimming bracket of the dimming module through the air guiding component 400. The duct air outlet of the heat dissipation duct 200 can move together with the dimming movement of the dimming module to ensure that the dimming module is always in the best heat dissipation state.
[0065] In another embodiment, the heating component 500 is a lens module. The air outlet of the duct is arranged towards the heat dissipation fins of the lens module and is fixed to the lens bracket of the lens module through the air guiding component 400.
[0066] The vehicle disclosed by the present utility model includes the above-mentioned vehicle lamp, so it also has the above-mentioned structure and beneficial effects. Other structures refer to the prior art and will not be elaborated herein.
[0067] The above description of the disclosed embodiments enables those skilled in the art to implement or use the present utility model. Various modifications to these embodiments will be obvious to those skilled in the art. The general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present utility model. The specific technical means in some embodiments can be partially or wholly incorporated into another embodiment on the premise that it is not explicitly excluded by another embodiment. Therefore, the present utility model will not be limited to these embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
