[0034] In the related art, as the power of the light source increases, the heat generated by the light source also increases accordingly, which brings great challenges to the heat dissipation design of the automobile taillights.

[0035] Reference below Figure 1-Figure 4 A tail lamp assembly 1 according to an embodiment of the present utility model is described.

[0036] like Figure 1 As shown, according to the utility model, the taillight assembly 1 is used for a vehicle, and the taillight assembly 1 includes a light distribution mirror 11, a taillight heat sink 12, a light emitting component 13 and a cooling component 14. The light distribution mirror 11 is formed with an open accommodating cavity 111; the taillight heat sink 12 is arranged on the light distribution mirror 11 and closes the accommodating cavity 111, and a first heat sink 121 extending in a direction away from the accommodating cavity 111 is formed on at least a portion of the surface of the taillight heat sink 12 away from the accommodating cavity 111; the light emitting component 13 is arranged in the accommodating cavity 111 and is fitted with the taillight heat sink 12 so as to be suitable for heat exchange with the taillight heat sink 12, and the light emitting component 13 is suitable for generating light transmitted toward the light distribution mirror 11; the cooling component 14 is formed with a cooling surface 141, and the cooling surface 141 is fitted with at least another portion of the surface of the taillight heat sink 12 away from the accommodating cavity 111 to absorb the heat of the taillight heat sink 12.

[0037] According to the taillight assembly 1 of the utility model, by providing a light distribution mirror 11, the light distribution mirror 11 forms an open accommodating cavity 111, and the accommodating cavity 111 can accommodate the light-emitting component 13. When the light-emitting component 13 generates light in the accommodating cavity 111, the light distribution mirror 11 can play a role in distributing light, so that the light emitted by the taillight assembly 1 meets the lighting and signal requirements of the vehicle. By providing a taillight heat sink 12, the taillight heat sink 12 is arranged on the light distribution mirror 11 and closes the accommodating cavity 111, so that the light-emitting component 13 is enclosed in the accommodating cavity 111, and the accommodating cavity 111 provides a stable operating environment for the light-emitting component 13, and the taillight heat sink 12 and the light distribution mirror 11 can jointly protect the light-emitting component 13, so as to achieve stable operation of the light-emitting component 13. By fitting the light-emitting component 13 in the accommodating cavity 111 with the taillight heat sink 12, effective heat exchange can be performed between the light-emitting component 13 and the taillight heat sink 12, and the heat generated by the light-emitting component 13 can be transferred to the outside of the accommodating cavity 111 through the taillight heat sink 12. The taillight heat sink 12 has a first heat sink 121 extending in a direction away from the accommodating cavity 111 formed on at least a portion of the surface away from the accommodating cavity 111. The first heat sink 121 can effectively increase the heat dissipation area, and help the taillight heat sink 12 to better dissipate the heat generated by the light-emitting component 13. By providing a refrigeration component 14, a refrigeration surface 141 of the refrigeration component 14 is arranged to fit at least another portion of the surface of the taillight heat sink 12 away from the accommodating cavity 111, so that the refrigeration component 14 can absorb the heat of the taillight heat sink 12, further helping the taillight heat sink 12 to cool down, and can effectively improve the heat dissipation efficiency of the taillight assembly 1, so that the taillight assembly 1 can maintain excellent performance even when working for a long time.

[0038] Therefore, according to the taillight assembly 1 of the present invention, by optimizing the heat dissipation design and providing the refrigeration component 14 , the heat dissipation performance of the taillight assembly 1 is effectively improved, thereby improving the stability and reliability of the taillight assembly 1 .

[0039] According to some embodiments of the present invention, Figure 1As shown, the refrigeration assembly 14 includes a first element and a second element, the first element is formed with a refrigeration surface 141; the second element is arranged on the surface of the first element away from the refrigeration surface 141 and is electrically connected to the first element, and the surface of the second element away from the first element is configured as a heat dissipation surface 142; when the direct current flows from the first element to the second element, the heat dissipation surface 142 releases heat; when the direct current flows from the second element to the first element, the refrigeration surface 141 absorbs heat. By arranging the first element, the first element is formed with a refrigeration surface 141, and when the refrigeration assembly 14 is working, the refrigeration surface 141 absorbs heat to help the taillight heat sink 12 cool down. By arranging the second element, the second element is arranged on the surface of the first element away from the refrigeration surface 141, and the surface of the second element away from the first element is configured as a heat dissipation surface 142, and the function of the heat dissipation surface 142 is to release heat to maintain the thermal balance between the refrigeration assembly 14 and the taillight heat sink 12. The absorption of heat by the refrigeration surface 141 and the release of heat by the heat dissipation surface 142 are based on the principle of thermoelectric effect, and are achieved by the flow of direct current between the first element and the second element. When the direct current flows from the first element to the second element, the heat is transferred from the cooling surface 141 of the first element to the second element, and released to the environment by the heat dissipation surface 142 of the second element, so that the cooling component 14 can effectively dissipate the heat absorbed by the tail light heat sink 12. When the direct current flows from the second element to the first element, the temperature of the cooling surface 141 decreases and a temperature difference is generated with the tail light heat sink 12, and the cooling surface 141 begins to absorb heat, helping the tail light heat sink 12 to cool down to improve the heat dissipation efficiency of the tail light assembly 1.

[0040] According to some embodiments of the present invention, Figure 2-Figure 4 As shown, the first element and the second element are respectively provided with terminals suitable for connecting to a power source, and the refrigeration assembly 14 further includes a wiring harness 144, which is configured as two terminals corresponding to the first element and the second element, one end of each wiring harness 144 is connected to a corresponding terminal, and the other end of the wiring harness 144 is suitable for connecting to a power source. By respectively providing terminals on the first element and the second element, the terminals can be stably connected to the wiring harness 144, so that the current is stably and safely transmitted, and the first element and the second element are both connected to the power source through the wiring harness 144, so that the power source supplies power to the first element and the second element, and a DC circuit flows between the first element and the second element.

[0041] According to some embodiments of the present invention, Figure 1-Figure 4As shown, the refrigeration assembly 14 also includes a refrigeration heat sink 143, which is arranged on the heat dissipation surface 142. A second heat sink 1431 extending in a direction away from the heat dissipation surface 142 is formed on the surface of the refrigeration heat sink 143 away from the heat dissipation surface 142. By setting the refrigeration heat sink 143, the refrigeration heat sink 143 is arranged on the heat dissipation surface 142 of the second element, so that the refrigeration heat sink 143 can absorb the heat released by the heat dissipation surface 142, thereby quickly dissipating and transferring the heat. A second heat sink 1431 extending in a direction away from the heat dissipation surface 142 is formed on the surface of the refrigeration heat sink 143 away from the heat dissipation surface 142. The second heat sink 1431 is in contact with the air to increase the heat dissipation area and improve the heat dissipation efficiency. Through the second heat sink 1431, the refrigeration heat sink 143 can more effectively dissipate heat to the surrounding environment, thereby improving the heat dissipation efficiency of the taillight assembly 1.

[0042] According to some embodiments of the utility model, by providing a refrigeration component 14, the heat dissipation performance of the refrigeration component 14 can effectively replace or supplement the role of the anodizing process in enhancing the heat dissipation performance of the taillight assembly 1. Therefore, the anodizing process of the refrigeration heat sink 143 can be eliminated, thereby further reducing the production cost, simplifying the production process, and improving the production efficiency, providing strong support for the mass production of the product.

[0043] According to some embodiments of the utility model, a through hole for the wire harness 144 to pass through is formed on the cooling and radiating element 143. By providing the through hole on the cooling and radiating element 143, the wire harness 144 can pass through the through hole to facilitate the arrangement of the wire harness 144, so that the wire harness 144 can conveniently electrically connect the first element and the second element to the power supply respectively, and the through hole can also limit the movement of the wire harness 144, so that the wire harness 144 can transmit current more stably.

[0044] According to some embodiments of the present invention, Figure 1As shown, the first heat sink 121 is constructed as a plurality of spaced-apart fins to define a heat dissipation gap between any two adjacent first heat sinks 121, and the plurality of first heat sinks 121 are arranged in a surrounding manner to define a receiving groove between each other, and at least a portion of the refrigeration assembly 14 is arranged in the receiving groove. By constructing the first heat sink 121 as a plurality of spaced-apart fins, a heat dissipation gap can be defined between any two adjacent first heat sinks 121, and the heat dissipation gap is crucial for air circulation. The heat dissipation gap allows air to flow freely through the first heat sink 121, helping to take away the heat on the first heat sink 121, further increasing the heat dissipation area, and improving the heat dissipation efficiency. By arranging the plurality of first heat sinks 121 in a surrounding manner, the plurality of first heat sinks 121 form a receiving groove between each other, and the receiving groove provides a suitable installation space for the refrigeration assembly 14. By arranging at least a portion of the refrigeration assembly 14 in the receiving groove, a close combination between the refrigeration heat sink 143 and the refrigeration assembly 14 is achieved, so that heat can be effectively transferred and dissipated, and the heat dissipation performance of the taillight assembly 1 is significantly improved.

[0045] According to some embodiments of the present invention, Figure 1 As shown, the cooling and radiating element 143 and the inner wall of the receiving groove are spaced apart from each other. The cooling and radiating element 143 and the inner wall of the receiving groove are spaced apart from each other, so that the heat of the cooling and radiating element 143 is not easily transferred to the tail light radiating element 12, which helps to maintain the temperature of the tail light radiating element 12, so that the tail light radiating element 12 can continuously absorb the heat of the light emitting assembly 13. In addition, air can flow freely between the cooling and radiating element 143 and the inner wall of the receiving groove, thereby enhancing the heat dissipation effect.

[0046] According to some embodiments of the utility model, in the extension direction of the cooling heat sink, the distance between the cooling heat sink 143 and the inner wall of the receiving groove is d and satisfies: d≥5mm. The distance d between the cooling heat sink 143 and the inner wall of the receiving groove is equivalent to the distance generated by the cooling heat sink continuing to extend to the inner wall of the receiving groove. The distance d is greater than or equal to 5 mm, which helps to reduce the heat conduction between the cooling heat sink 143 and the inner wall of the receiving groove, and the heat is difficult to transfer from the cooling heat sink 143 to the taillight heat sink 12, so that the heat can be easily dissipated to the environment through the cooling heat sink 143, and it helps to maintain the low temperature state of the taillight heat sink 12; and, there is sufficient space for air flow between the cooling heat sink 143 and the inner wall of the receiving groove, so that the air can flow smoothly through the cooling heat sink 143 and effectively take away the heat on the second heat sink 1431.

[0047] According to some embodiments of the present invention, Figure 1As shown, the light-emitting assembly 13 includes a circuit board 131 and a light-emitting element 132. One side surface of the circuit board 131 is fitted with the taillight heat sink 12; the light-emitting element 132 is arranged on the other side surface of the circuit board 131 and is suitable for generating light that is transmitted toward the lens 11. The circuit board 131 is the basis of the light-emitting assembly 13, providing the functions of circuit connection and supporting the light-emitting element 132. The light-emitting element 132 can generate light, such as an LED light. By fitting one side surface of the circuit board 131 with the taillight heat sink 12, it helps to effectively transfer the heat generated by the light-emitting assembly 13 to the taillight heat sink 12 through the circuit board 131, and then dissipate the heat into the surrounding environment through the taillight heat sink 12, thereby achieving stable operation of the light-emitting assembly 13 and preventing the light-emitting assembly 13 from overheating. By arranging the light-emitting component 132 on the other side surface of the circuit board 131, the circuit board 131 can provide electrical energy to the light-emitting component 132 and control the operation of the light-emitting component 132. Under the control of the circuit board 131, the light-emitting component 132 can generate light that is transmitted toward the light distribution mirror 11, and the light distribution mirror 11 distributes and guides the light to the outside to realize the lighting and signal functions of the taillight assembly 1.

[0048] According to some embodiments of the present invention, the light emitting component 13, the first element and the second element are powered by a power supply with the same voltage, thereby simplifying the overall circuit layout and improving the integration and reliability of the system.

[0049] According to some embodiments of the utility model, when the long-term high-power use function is activated, the first element and the second element cooperate to provide instant cooling, effectively suppressing the heat dissipation problem of the taillight assembly 1 when running under high load, without adding additional control circuits, which not only improves the heat dissipation effect, but also avoids the complexity of adding logic judgment circuits, reduces costs and improves the response speed of the system.

[0050] According to some embodiments of the present invention, Figure 1 As shown, a surrounding card slot 122 is formed on the taillight heat sink 12, and a card connection portion 112 adapted to the card slot 122 is formed on the edge of the light distribution mirror 11, and the card connection portion 112 is card-engaged with the card slot 122. By providing a surrounding card slot 122 on the taillight heat sink 12 and card-engaging with the card connection portion 112 on the edge of the light distribution mirror 11, a close connection between the taillight heat sink 12 and the light distribution mirror 11 is achieved, and the taillight heat sink 12 can effectively close the accommodating cavity 111, so as to achieve sealing of the accommodating cavity 111. The card-engaging method simplifies the installation process of the taillight heat sink 12 and the light distribution mirror 11, and improves the assembly efficiency.

[0051] According to some embodiments of the utility model, an adhesive layer is provided in the card slot 122, and the adhesive layer is attached between the inner wall of the card slot 122 and the clamping portion 112 to bond and connect the light distribution mirror 11 to the tail light heat sink 12. By providing the adhesive layer, a tight bonding force is formed between the card slot 122 and the clamping portion 112, so that the light distribution mirror 11 and the tail light heat sink 12 can be connected and fixed. At the same time, the adhesive layer can also fill the small gap between the card slot 122 and the clamping portion 112 to improve the sealing of the connection.

[0052] According to some embodiments of the present invention, Figure 1 As shown, the light distribution mirror 11 extends a sealing portion 113 at the position of the opening of the card slot 122, and the sealing portion 113 extends in a direction away from the accommodating cavity 111 and fits with the surface of the tail light heat sink 12 to close the opening of the card slot 122. By arranging the sealing portion 113 on the light distribution mirror 11, when the clamping portion 112 cooperates with the card slot 122, the sealing portion 113 is at the position of the opening of the card slot 122 and extends in a direction away from the accommodating cavity 111, and the sealing portion 113 can fit on the surface of the tail light heat sink 12, thereby effectively closing the opening of the card slot 122, which not only enhances the sealing performance of the tail light assembly 1, but also improves the connection stability between the tail light heat sink 12 and the light distribution mirror 11.
