Technical Field
[0001] This utility model relates to the field of vehicle lighting technology, and more specifically, to a vehicle lighting system that facilitates heat dissipation. Background Technology
[0002] Vehicle lights that are easy to dissipate heat refer to vehicle lighting systems that use a series of active or passive thermal management designs and technologies to efficiently, quickly and continuously transfer the waste heat generated inside the vehicle lights to the external environment, thereby ensuring that the vehicle lights always work within a safe, efficient and stable temperature range. However, existing vehicle lighting systems, especially at night, need to be turned on for a long time, generating a lot of heat. Over time, this can easily lead to internal overheating, which can shorten the lifespan of the device. Utility Model Content
[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a vehicle lamp that facilitates heat dissipation and has the advantage of improving heat dissipation effect.
[0004] To achieve the above objectives, this utility model provides the following technical solution: a vehicle light with convenient heat dissipation, comprising a housing, an upper cover plate fixedly installed on the top of the housing, a lower cover plate provided at the bottom of the housing, a bolt inserted into the interior of the lower cover plate, the bolt engaging with the housing, a cooling fan and a heat-conducting plate fixedly installed inside the housing, a light source fixedly installed above the heat-conducting plate, a solenoid valve fixedly installed on the left side of the heat-conducting plate, a lens bracket fixedly installed on the left side of the housing, a convex lens fixedly installed inside the lens bracket, and a reflector fixedly installed on the top of the housing.
[0005] As a preferred embodiment of this utility model, a connecting plate is fixedly installed at the bottom of the heat-conducting plate, a base plate is fixedly installed at the bottom of the connecting plate, a phase change heat-conducting pad is provided on the outer side of the base plate, and the phase change heat-conducting pad is attached to the base plate.
[0006] As a preferred embodiment of this utility model, a support frame is fixedly installed on the outer side of the substrate, a sliding groove is provided inside the support frame, a slider is slidably connected inside the sliding groove, a clamping plate is fixedly installed on the outer side of the slider, a heat dissipation hole is provided inside the clamping plate, a telescopic rod is fixedly installed on the right side of the heat dissipation hole, a spring is sleeved on the outer side of the telescopic rod, and the end of the spring away from the heat dissipation hole is fixedly connected to the support frame.
[0007] As a preferred embodiment of this utility model, there are multiple heat dissipation holes, all of which are located inside the clamping plate and inside the outer shell.
[0008] As a preferred embodiment of this utility model, dustproof holes are provided inside both the upper and lower cover plates, and the dustproof holes are located on the upper and lower sides of the cooling fan, respectively.
[0009] As a preferred embodiment of this utility model, the lens holder and the housing are hollow inside, and the lens holder is located on the left side of the housing.
[0010] As a preferred embodiment of this utility model, the lower cover plate and the upper cover plate are located on the upper and lower sides of the cooling fan, respectively, and both the upper cover plate and the lower cover plate are L-shaped.
[0011] As a preferred embodiment of this utility model, there are two telescopic rods and two springs, which are distributed front and back respectively.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0013] 1. This utility model features a substrate fixedly mounted at the bottom of a connecting plate. A phase change thermal pad is provided on the outer side of the substrate and is in contact with the substrate. When the light source is activated and generates significant heat, the heat is transferred to the bottom of the connecting plate through the thermal conductive plate. Simultaneously, a layer of solid phase change material is pre-attached to the inner side of the substrate where the phase change thermal pad contacts the substrate. This material is solid at room temperature but softens when the temperature rises to 45°-60°C, filling all microscopic gaps like a paste, greatly reducing contact thermal resistance and thus improving overall heat dissipation efficiency. Combined with a cooling fan, this allows heat inside the casing to dissipate quickly, extending the device's lifespan.
[0014] 2. This utility model features a slider slidably connected inside a groove, a clamping plate fixedly installed on the outside of the slider, heat dissipation holes inside the clamping plate, a telescopic rod fixedly installed on the right side of the heat dissipation holes, and a spring sleeved on the outside of the telescopic rod. The end of the spring away from the heat dissipation holes is fixedly connected to a support frame. The clamping plate contacts the phase change thermal pad and is located at the end of the phase change thermal pad away from the substrate. Simultaneously, the clamping plate is compressed by the elastic force of the spring, thus fixing the phase change thermal pad in constant contact with the substrate. When the vehicle shakes during driving, the telescopic rod, in conjunction with the spring, absorbs the vibration. At the same time, the spring continuously provides elastic force to compress the phase change thermal pad with the clamping plate, ensuring that the phase change thermal pad remains in constant contact with the substrate, thus achieving a stable clamping effect for the phase change thermal pad.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.
[0022] like Figures 1 to 5 As shown, this utility model provides a vehicle light that facilitates heat dissipation, including a housing 1, an upper cover plate 2 fixedly installed on the top of the housing 1, a lower cover plate 3 provided at the bottom of the housing 1, a bolt 4 inserted into the interior of the lower cover plate 3, the bolt 4 engaging with the housing 1, a cooling fan 5 and a heat-conducting plate 6 fixedly installed inside the housing 1, a light source 7 fixedly installed above the heat-conducting plate 6, a solenoid valve 8 fixedly installed on the left side of the heat-conducting plate 6, a lens bracket 9 fixedly installed on the left side of the housing 1, a convex lens 10 fixedly installed inside the lens bracket 9, and a reflector cup 11 fixedly installed on the top of the housing 1.
[0023] When illumination is required by the headlights, the light source 7 is activated first. At the same time, the light source is concentrated by the solenoid valve 8 and the reflector cup 11. The light source is then reflected into the interior of the convex lens 10, which focuses the light again, achieving the effect of focusing the light outward, thereby achieving long-distance illumination. Meanwhile, the lens bracket 9 supports the convex lens 10, keeping the convex lens 10 stable as a whole.
[0024] Among them, a connecting plate 12 is fixedly installed at the bottom of the heat-conducting plate 6, and a substrate 13 is fixedly installed at the bottom of the connecting plate 12. A phase change heat-conducting pad 14 is provided on the outer side of the substrate 13, and the phase change heat-conducting pad 14 is attached to the substrate 13.
[0025] When the light source 7 is activated and generates significant heat, this heat is transferred to the bottom of the connecting plate 12 via the heat-conducting plate 6. Simultaneously, the phase change thermal pad 14 contacts the inner side of the substrate 13, where a layer of solid phase change material is pre-attached. This material is solid at room temperature but softens when the temperature rises to 45°-60°, filling all microscopic gaps like a paste, greatly reducing contact thermal resistance and thus improving overall heat dissipation efficiency. Combined with the cooling fan 5, this allows the heat inside the outer casing 1 to dissipate quickly, maintaining the device's lifespan.
[0026] A support frame 15 is fixedly installed on the outer side of the substrate 13. A sliding groove 16 is provided inside the support frame 15. A slider 17 is slidably connected inside the sliding groove 16. A clamping plate 18 is fixedly installed on the outer side of the slider 17. A heat dissipation hole 19 is provided inside the clamping plate 18. A telescopic rod 20 is fixedly installed on the right side of the heat dissipation hole 19. A spring 21 is sleeved on the outer side of the telescopic rod 20. The end of the spring 21 away from the heat dissipation hole 19 is fixedly connected to the support frame 15.
[0027] The clamping plate 18 contacts the phase change thermal pad 14 and is located at the end of the phase change thermal pad 14 away from the substrate 13. At the same time, the clamping plate 18 is squeezed by the elastic force of the spring 21, so that the phase change thermal pad 14 is fixed and always in contact with the substrate 13. When the vehicle shakes during driving, the telescopic rod 20 works with the spring 21 to absorb the vibration. At the same time, the spring 21 always provides elastic force to squeeze the clamping plate 18 to the phase change thermal pad 14, so that the phase change thermal pad 14 is always in contact with the substrate 13, and the phase change thermal pad 14 has the effect of being clamped and kept stable.
[0028] There are multiple heat dissipation holes 19, all of which are located inside the clamping plate 18 and inside the outer shell 1.
[0029] The main function of the multiple heat dissipation holes 19 is to keep the phase change thermal pad 14 breathable at all times, thereby increasing the heat dissipation effect of the phase change thermal pad 14.
[0030] Dustproof holes are provided inside both the upper cover plate 2 and the lower cover plate 3, and the dustproof holes are located on the upper and lower sides of the cooling fan 5, respectively.
[0031] The main function of the dustproof hole is to prevent the large amount of dust generated during vehicle operation from causing dust inside the cooling fan 5, which would reduce its service life.
[0032] The lens holder 9 and the housing 1 are hollow inside, and the lens holder 9 is located on the left side of the housing 1.
[0033] The main function of the lens bracket 9 and the housing 1 is to support all components while maintaining a relatively sealed interior, preventing internal components from falling off and being damaged.
[0034] The lower cover plate 3 and the upper cover plate 2 are located on the upper and lower sides of the cooling fan 5, respectively, and both the upper cover plate 2 and the lower cover plate 3 are L-shaped.
[0035] During the connection process between the upper cover plate 2 and the lower cover plate 3 and the outer casing 1, the cooling fan 5 is fixed, making it easy to install the cooling fan 5 in the designated position.
[0036] There are two telescopic rods 20 and two springs 21, with the two telescopic rods 20 and the two springs 21 distributed in front and behind respectively.
[0037] The main function of the two telescopic rods 20 and the two springs 21 is to maintain the balance of the force on the clamping plate 18 by the heat dissipation hole 19, so that the phase change heat conduction pad 14 can be stably attached to the substrate 13.
[0038] Working principle and usage process of this utility model:
[0039] First, a cooling fan 5 and a heat-conducting plate 6 are fixedly installed inside the outer casing 1. A light source 7 is fixedly installed above the heat-conducting plate 6. A solenoid valve 8 is fixedly installed on the left side of the heat-conducting plate 6. A lens bracket 9 is fixedly installed on the left side of the outer casing 1. A convex lens 10 is fixedly installed inside the lens bracket 9. At the same time, a reflector cup 11 is fixedly installed above the outer casing 1. When headlights are needed for illumination, the light source 7 is activated first. The solenoid valve 8 and the reflector cup 11 concentrate the light source and reflect it into the convex lens 10, allowing the convex lens 10 to focus the light again, achieving the effect of focusing the light outward, thus achieving long-distance illumination. Meanwhile, the lens bracket 9 supports the convex lens 10, keeping the convex lens 10 stable as a whole.
[0040] Secondly, a substrate 13 is fixedly installed at the bottom of the connecting plate 12. A phase change thermal pad 14 is provided on the outer side of the substrate 13 and is attached to the substrate 13. When the light source 7 is activated and generates a large amount of heat, the heat will be transferred to the bottom of the connecting plate 12 through the heat conduction plate 6. At the same time, the phase change thermal pad 14 contacts the inner side of the substrate 13 and a layer of solid phase change material is pre-attached. This material is solid at room temperature, but softens when the temperature rises to 45°-60°, filling all the microscopic gaps like a paste, greatly reducing the contact thermal resistance, thereby improving the overall heat dissipation efficiency. Together with the cooling fan 5, the heat inside the outer casing 1 is quickly dissipated, thus maintaining the service life of the device.
[0041] Finally, a slider 17 is slidably connected inside the slide groove 16, and a clamping plate 18 is fixedly installed on the outside of the slider 17. A heat dissipation hole 19 is opened inside the clamping plate 18, and a telescopic rod 20 is fixedly installed on the right side of the heat dissipation hole 19. A spring 21 is sleeved on the outside of the telescopic rod 20, and the end of the spring 21 away from the heat dissipation hole 19 is fixedly connected to the support frame 15. The clamping plate 18 contacts the phase change heat conduction pad 14 and is located at the end of the phase change heat conduction pad 14 away from the substrate 13. At the same time, the clamping plate 18 is squeezed by the elastic force of the spring 21, so that the phase change heat conduction pad 14 is fixed and always in contact with the substrate 13. When the vehicle shakes during driving, the telescopic rod 20 and the spring 21 absorb the vibration. At the same time, the spring 21 always provides elastic force to make the clamping plate 18 squeeze the phase change heat conduction pad 14, so that the phase change heat conduction pad 14 is always in contact with the substrate 13, and the phase change heat conduction pad 14 has the effect of being clamped and kept stable.
