Description

Technical Field

[0001] This utility model relates to the field of LED automotive headlight technology, and in particular to a heat dissipation structure for LED automotive headlights. Background Technology

[0002] The heat dissipation structure of LED automotive headlights is a key part of ensuring the stable and efficient operation of LEDs in automotive headlights. Since LEDs generate heat when working, if the heat cannot be dissipated in time, it will cause the LED to exceed the critical junction temperature, resulting in dimming and color changes, and will also affect its lifespan and luminous efficiency. The heat dissipation structure mainly achieves heat dissipation through air cooling and liquid cooling.

[0003] Traditional automotive headlight cooling methods often suffer from low heat dissipation efficiency, leading to excessively high temperatures after prolonged use, which affects their lighting performance and lifespan. Utility Model Content

[0004] The purpose of this invention is to provide a heat dissipation structure for LED automotive headlights to solve at least one of the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an LED automotive headlight heat dissipation structure, including a housing, and further comprising:

[0006] A heat dissipation mechanism is provided on the housing. The heat dissipation mechanism includes a headlight disposed inside the housing. The heat dissipation mechanism is used to dissipate heat from the headlight to ensure that the headlight's service life is not reduced due to high temperature.

[0007] A cleaning mechanism is provided inside the housing. The cleaning mechanism includes a drive shaft located inside the housing. The cleaning mechanism is used to clean dust from the heat dissipation mechanism to ensure that dust does not affect normal heat dissipation.

[0008] Preferably, the heat dissipation mechanism includes a headlight fixedly installed inside the housing, the front of the headlight extending outside the housing, a liquid storage tank fixedly installed on the back of the headlight, and a plurality of heat dissipation pipes fixedly installed on the top of the liquid storage tank.

[0009] Preferably, an air inlet pipe is fixedly installed inside the housing, and the front of the air inlet pipe has several air inlet holes. Two limiting plates are fixedly installed inside the housing.

[0010] Preferably, a limiting groove is formed on the bottom inner wall of the air inlet pipe, and an irregularly shaped limiting plate is fixedly installed inside the air inlet pipe, with the bottom end of the irregularly shaped limiting plate extending to the outside of the air inlet pipe.

[0011] Preferably, the cleaning mechanism includes a drive shaft rotatably mounted on the inner wall of the top of the housing, and a plurality of drive blades are fixedly mounted on the drive shaft.

[0012] Preferably, a plurality of scrapers are slidably mounted on the plurality of heat dissipation pipes, and a connecting plate is fixedly mounted on the back of the plurality of scrapers.

[0013] Preferably, a strip plate is fixedly installed on the back of the connecting plate, and a limit spring is fixedly installed on the top of the strip plate, with the top end of the limit spring being fixedly connected to the top inner wall of the housing.

[0014] Preferably, the top of the housing has several air outlets, the top of the strip plate is fixedly mounted with a triangular plate, and the outer wall of the drive shaft is fixedly mounted with a contact plate.

[0015] The beneficial effects of this utility model are as follows:

[0016] In this utility model:

[0017] 1. When the headlights are on, air enters the air intake duct through the air intake hole while the vehicle is in motion. The air intake hole filters out larger impurities in the air. The air then enters the housing through the air intake duct and is blown towards several cooling pipes by the air deflector. The heat generated by the headlights is transferred to the reservoir. The liquid in the reservoir vaporizes and fills the entire cooling pipe. The heat is also transferred to the inner wall of the cooling pipe through the vaporized liquid. The air carries away the heat from the cooling pipe and exhausts it through the air outlet, thus continuously cooling the headlights while the vehicle is in motion.

[0018] 2. When air enters the housing, it drives several drive fan blades to rotate. The drive fan blades drive the drive shaft to rotate, which in turn drives the contact plate to rotate. The contact plate contacts the triangular plate, which descends under the action of the inclined plane. At this time, the limit spring will stretch and deform. The triangular plate will drive the strip plate to descend, which in turn drives the connecting plate to descend. The connecting plate will drive several scrapers to descend, which will scrape several heat pipes. After the contact plate leaves the triangular plate, under the elastic force of the limit spring, the scrapers will move up and down to clean the dust on the heat pipes. The cleaned dust will enter the air inlet pipe under the limiting action of the limit plate, and then leave the air inlet pipe under the limiting action of the irregularly shaped limit plate.

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.

[0026] This utility model provides, for example Figure 1-5 The diagram illustrates a heat dissipation structure for an LED automotive headlight, comprising a housing 1 and further including: a heat dissipation mechanism disposed on the housing 1, comprising a headlight 101 disposed within the housing 1, the heat dissipation mechanism being used to dissipate heat from the headlight 101 to ensure that the headlight 101 does not experience a reduction in lifespan due to high temperatures; and a cleaning mechanism disposed within the housing 1, comprising a drive shaft 2 disposed within the housing 1, the cleaning mechanism being used to clean dust from the heat dissipation mechanism to ensure that dust does not affect normal heat dissipation. The heat dissipation mechanism includes a headlight 101 fixedly installed within the housing 1, with the front of the headlight 101 extending outside the housing 1, and a liquid reservoir 102 fixedly installed on the back of the headlight 101. Several heat dissipation pipes 103 are fixedly installed on the top of the liquid reservoir 102. An air inlet pipe 104 is fixedly installed within the housing 1, with several air inlet holes 105 on the front of the air inlet pipe 104. Two limiting plates 106 are fixedly installed within the housing 1. A limiting groove 107 is provided on the bottom inner wall of the air inlet pipe 104, and an irregularly shaped limiting plate 108 is fixedly installed inside the air inlet pipe 104, with the bottom end of the irregularly shaped limiting plate 108 extending to the outside of the air inlet pipe 104.

[0027] When in use, the headlights are turned on. During vehicle operation, air enters the air intake duct 104 through the air intake vent 105. The air intake vent 105 filters out larger impurities in the air. The air then enters the housing 1 through the air intake duct 104. Guided by the air guide plate 202, the air is blown towards several heat dissipation pipes 103. The heat generated by the headlights 101 is transferred to the liquid reservoir 102. The liquid in the liquid reservoir 102 vaporizes and fills the entire heat dissipation pipe 103. The heat is also transferred to the inner wall of the heat dissipation pipe 103 through the vaporized liquid. The heat on the heat dissipation pipe 103 is carried away by the airflow and discharged through the air outlet 207, thereby continuously cooling the headlights 101 during vehicle operation.

[0028] The cleaning mechanism includes a drive shaft 2 rotatably mounted on the inner wall of the top of the housing 1, with several drive fan blades 201 fixedly mounted on the drive shaft 2. Several scrapers 203 are slidably mounted on several heat dissipation pipes 103, and connecting plates 204 are fixedly mounted on the back of the scrapers 203. A strip plate 205 is fixedly mounted on the back of the connecting plate 204, and a limit spring 206 is fixedly mounted on the top of the strip plate 205. The top of the limit spring 206 is fixedly connected to the inner wall of the top of the housing 1.

[0029] When air enters the housing 1, it drives several drive fan blades 201 to rotate. The drive fan blades 201 drive the drive shaft 2 to rotate, and the drive shaft 2 drives the contact plate 209 to rotate. The contact plate 209 contacts the triangular plate 208, and the triangular plate 208 descends under the action of the inclined plane. At this time, the limiting spring 206 will be stretched and deformed. The triangular plate 208 will drive the strip plate 205 to descend, and the strip plate 205 will drive the connecting plate 204 to descend. The connecting plate 204 will drive several scrapers 203 to descend. The scrapers 203 will scrape the heat dissipation pipes 103. After the contact plate 209 leaves the triangular plate 208, under the elastic force of the limiting spring 206, the scrapers 203 will move up and down to clean the dust on the heat dissipation pipes 103. The cleaned dust will enter the air inlet pipe 104 under the limiting action of the limiting plate 106, and leave the air inlet pipe 104 under the limiting action of the irregular limiting plate 108.

[0030] The working principle of the LED automotive headlight heat dissipation structure provided by this utility model is as follows:

[0031] When in use, the headlights are turned on. During vehicle operation, air enters the air intake duct 104 through the air intake 105. The air intake 105 filters out larger impurities in the air. The air then enters the housing 1 through the air intake duct 104. Guided by the air guide plate 202, the air is blown towards several heat dissipation pipes 103. The heat generated by the headlights 101 is transferred to the liquid reservoir 102. The liquid in the liquid reservoir 102 vaporizes and fills the entire heat dissipation pipe 103. The heat is also transferred to the inner wall of the heat dissipation pipe 103 through the vaporized liquid. The heat on the heat dissipation pipe 103 is carried away by the wind and discharged from the air outlet 207, thereby continuously cooling the headlights 101 during vehicle operation.

[0032] When air enters the housing 1, it drives several drive fan blades 201 to rotate. The drive fan blades 201 drive the drive shaft 2 to rotate, and the drive shaft 2 drives the contact plate 209 to rotate. The contact plate 209 contacts the triangular plate 208, and the triangular plate 208 descends under the action of the inclined plane. At this time, the limiting spring 206 will be stretched and deformed. The triangular plate 208 will drive the strip plate 205 to descend, and the strip plate 205 will drive the connecting plate 204 to descend. The connecting plate 204 will drive several scrapers 203 to descend. The scrapers 203 will scrape the heat dissipation pipes 103. After the contact plate 209 leaves the triangular plate 208, under the elastic force of the limiting spring 206, the scrapers 203 will move up and down to clean the dust on the heat dissipation pipes 103. The cleaned dust will enter the air inlet pipe 104 under the limiting action of the limiting plate 106, and leave the air inlet pipe 104 under the limiting action of the irregular limiting plate 108.
