[0035] Reference below Figure 1-Figure 3 A tail lamp assembly 1 according to an embodiment of the present utility model is described.

[0036] like Figure 1 and Figure 2 As shown, the taillight assembly 1 according to the utility model is used for a vehicle, and the taillight assembly 1 includes a light distribution mirror 11, a lamp housing 12, a light emitting component 13 and a cooling component 14. The lamp housing 12 is connected to the light distribution mirror 11 and defines a receiving cavity between the lamp housing 12 and the light distribution mirror 11. The lamp housing 12 is provided with a ventilating portion 121 for gas exchange between the receiving cavity and the external environment; the light emitting component 13 is arranged in the receiving cavity and is suitable for generating light transmitted toward the light distribution mirror 11; the cooling component 14 is arranged on the lamp housing 12 and is located outside the receiving cavity; wherein the cooling component 14 is formed with a cooling surface 141, and the lamp housing 12 is formed with a mating surface, and the cooling surface 141 is arranged in contact with the mating surface to absorb the heat of the lamp housing 12.

[0037] According to the taillight assembly 1 of the utility model, by providing the photometric lens 11, the photometric lens 11 can adjust and control the distribution and direction of the light emitted from the light-emitting component 13, so that the light can be irradiated according to the design requirements, and the lighting and signal prompting effects are achieved. By providing the lamp housing 12, the lamp housing 12 is connected to the photometric lens 11, and a receiving cavity is defined between the lamp housing 12 and the photometric lens 11. Since the light-emitting component 13 is provided in the receiving cavity, the lamp housing 12 plays a role in protecting the light-emitting component 13, and also provides structural support for the taillight assembly 1. By providing the air permeable portion 121 on the lamp housing 12, the air permeable portion 121 allows gas exchange between the receiving cavity and the external environment, balances the air pressure between the receiving cavity and the external environment, and helps to dissipate heat and maintain the stability of the internal environment. By providing the light-emitting component 13, the light-emitting component 13 can generate light in the receiving cavity that is transmitted toward the photometric lens 11, and is responsible for providing the lighting and signal functions required by the taillight assembly 1. By setting a refrigeration component 14, the refrigeration component 14 is set on the lamp housing 12 and is located outside the accommodating cavity. The refrigeration component 14 forms a refrigeration surface 141, and the refrigeration surface 141 is arranged to fit the matching surface on the lamp housing 12, so that the refrigeration component 14 can absorb the heat on the lamp housing 12, help the taillight assembly 1 to dissipate heat, improve the heat dissipation efficiency of the taillight assembly 1, and enable the light-emitting component 13 to work stably under long-term high-power conditions, thereby extending the service life of the taillight assembly 1.

[0038] Therefore, according to the taillight assembly 1 of the present invention, by providing the refrigeration component 14 on the lamp housing 12 , the heat dissipation efficiency of the taillight assembly 1 is improved, so that the taillight assembly 1 can work stably and reliably, and the service life of the taillight assembly 1 is extended.

[0039] According to some embodiments of the present invention, Figure 1 As 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 assembly 1 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 lamp housing 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 lamp housing 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 lamp housing 12, and the cooling surface 141 begins to absorb heat, helping the lamp housing 12 to cool down to improve the heat dissipation efficiency of the taillight assembly 1.

[0040] According to some embodiments of the present invention, Figure 1 As shown, the refrigeration assembly 14 also includes a refrigeration heat sink 143, which is arranged on the heat dissipation surface 142. A first heat sink 1431 extending 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 extending 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 is in contact with the air to increase the heat dissipation area and improve the heat dissipation efficiency. Through the second heat sink, 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.

[0041] According to some embodiments of the present invention, Figure 1 and Figure 2As shown, the taillight assembly 1 also includes a power connector 15, on which a first wire harness 151 and a second wire harness 152 are arranged. The first wire harness 151 is electrically connected to the light-emitting assembly 13, and the second wire harness 152 is electrically connected to the cooling assembly 14. The power connector 15 is suitable for connecting to power to supply power to the light-emitting assembly 13 and the cooling assembly 14 respectively. By providing the power connector 15, the power connector 15 is used to connect and transmit power, so that the taillight assembly 1 can be easily connected to the power system of the vehicle, thereby obtaining the required power supply. By arranging the first wire harness 151 and the second wire harness 152 on the power connector 15, the first wire harness 151 is electrically connected to the light-emitting assembly 13, and the second wire harness 152 is electrically connected to the cooling assembly 14. Therefore, when the power connector 15 is connected to power, power can be supplied to the light-emitting assembly 13 and the cooling assembly 14 respectively, so that the taillight assembly 1 can work normally, can provide sufficient lighting and signals, and can maintain good heat dissipation performance. Specifically, the first wiring harness 151 is responsible for transmitting the power received by the power connector 15 to the light-emitting assembly 13, so that the light-emitting assembly 13 can emit light, thereby realizing the lighting and signaling functions of the taillight. The second wiring harness 152 is responsible for transmitting the power received by the power connector 15 to the cooling assembly 14, so that the cooling assembly 14 can work, thereby helping the taillight assembly 1 to dissipate heat and realize the stable operation of the taillight assembly 1.

[0042] According to some embodiments of the present invention, Figure 1 As shown, the light-emitting assembly 13 includes a circuit board 131 and a light-emitting element 132. The light-emitting element 132 is disposed on one side surface of the circuit board 131 and is suitable for generating light that is transmitted toward the light-distributing lens 11. The circuit board 131 is the basis of the light-emitting assembly 13, and provides 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 arranging the light-emitting element 132 on one side surface of the circuit board 131, the circuit board 131 can provide electrical energy to the light-emitting element 132 and control the operation of the light-emitting element 132. Under the control of the circuit board 131, the light-emitting element 132 can generate light that is transmitted toward the light-distributing lens 11, and the light-distributing lens 11 distributes and guides the light to the outside to realize the lighting and signaling functions of the taillight assembly 1.

[0043] According to some embodiments of the present invention, Figure 1As shown, the light-emitting assembly 13 also includes a light-emitting heat sink 133, which is arranged on the other side surface of the circuit board 131, and a second heat sink extending away from the circuit board 131 is formed on the surface of the light-emitting heat sink 133 away from the circuit board 131. The circuit board 131 and the light-emitting element 132 will generate heat when working. By providing the light-emitting heat sink 133, the light-emitting heat sink 133 can help the circuit board 131 and the light-emitting element 132 to dissipate heat, and keep the circuit board 131 and the light-emitting element 132 working stably. The light-emitting element 132 is arranged on one side surface of the circuit board 131, and the light-emitting heat sink 133 is arranged on the other side surface of the circuit board 131, which can more effectively conduct the heat generated by the circuit board 131 and the light-emitting element 132. A second heat sink is formed on the surface of the light-emitting heat sink 133 away from the circuit board 131, and the second heat sink extends away from the circuit board 131. The second heat sink increases the surface area of ​​the light-emitting heat sink 133, thereby increasing the heat dissipation area, so that the light-emitting heat sink 133 can dissipate heat more effectively. When the heat generated by the light emitting element 132 and the circuit board 131 during operation is conducted to the light emitting heat sink 133 , the heat will be dissipated through the second heat sink, thereby maintaining the normal operation of the light emitting assembly 13 .

[0044] According to some embodiments of the present invention, Figure 1 As shown, the lamp housing 12 is formed with a first extension portion 122 extending in the length direction of the vehicle, and the surface of the first extension portion 122 facing away from the accommodating cavity is configured as a mating surface suitable for carrying the refrigeration component 14. The first extension portion 122 extends in the length direction of the vehicle, that is, the first extension portion 122 extends along the front-rear direction of the vehicle. By configuring the surface of the first extension portion 122 facing away from the accommodating cavity as a mating surface, the mating surface can carry the refrigeration component 14, providing a stable installation position for the refrigeration component 14, facilitating the fixing and installation of the refrigeration component 14, so that the refrigeration component 14 can be stably installed on the lamp housing 12, and effectively absorb the heat on the lamp housing 12, and maintain the normal working temperature of the taillight assembly 1.

[0045] According to some embodiments of the present invention, Figure 1As shown, the lamp housing 12 is also formed with a second extension portion 123 extending in the length direction of the vehicle, the first extension portion 122 and the second extension portion 123 are spaced apart from each other in the height direction of the vehicle, and the light emitting assembly 13 is arranged on the second extension portion 123 and at least partially located between the first extension portion 122 and the second extension portion 123. The first extension portion 122 and the second extension portion 123 are not connected in the vertical direction, but there is a spacing distance. The space formed between the first extension portion 122 and the second extension portion 123 is a part of the accommodating cavity. By arranging at least part of the light emitting assembly 13 between the first extension portion 122 and the second extension portion 123, it is helpful to optimize the space utilization, and it may also help to improve the heat dissipation performance, because the heat generated by the light emitting assembly 13 when working can be more effectively dissipated through the cooling assembly on the first extension portion 122. At the same time, the second extension portion 123 extends in the length direction of the vehicle, providing a stable installation position for the light emitting assembly 13, so that the light emitting assembly 13 can be stably arranged on the second extension portion 123 to work reliably.

[0046] According to some embodiments of the present invention, Figure 2 As shown, the refrigeration component 14 is arranged adjacent to the air permeable portion 121. The air permeable portion 121 can allow gas to pass freely, help the car lamp dissipate heat, and prevent moisture and dust from entering the accommodating cavity. At the same time, the air permeable portion 121 can also balance the air pressure between the accommodating cavity and the external environment. By arranging the refrigeration component 14 adjacent to the air permeable portion 121, the ventilation function of the air permeable portion 121 can be fully utilized to enhance the heat dissipation effect of the refrigeration component 14. When the refrigeration component 14 is working, the refrigeration component 14 can conduct the heat generated by the light-emitting component 13 to the air permeable portion 121, and take away the heat with the help of the ventilation function of the air permeable portion 121, thereby improving the heat dissipation efficiency, helping to maintain the temperature of the taillight assembly 1 stable, and thus extending the service life of the taillight assembly 1.
