Description

Technical Field

[0001] This utility model relates to the field of headlight design and manufacturing technology, and in particular to a projectable DLP headlight. Background Technology

[0002] Currently, headlights play a crucial role in vehicle operation. Headlights typically include the functions of common headlights such as low beam, high beam, turn signals, and fog lights to ensure safe driving at night or in inclement weather and on various roads.

[0003] Related technology can be found in Chinese Patent No. CN219264041U, which discloses a combined headlight, including a lens, decorative strip, decorative frame, a shared inner lens for turn signal lights, a shared reflector for turn signal lights, a high beam module, a low beam lens assembly, wiring harness, and a lamp housing. The lamp housing is the main assembly component, with the remaining parts directly or indirectly fixed to it. This combined headlight is an irregular quadrilateral, divided into four functional areas in a grid pattern by the decorative strip and frame: high beam, low beam, turn signal, and turn signal areas, from top to bottom and left to right. This combined headlight has advantages such as rich functionality, novel design, and simple structure. By utilizing as many shared components as possible, it minimizes the number of parts and assembly difficulty, while also saving production costs.

[0004] Regarding the aforementioned technologies, the headlights, while ensuring daily use, have limited functionality. In outdoor camping scenarios, the headlights can only provide illumination to the user based on the existing headlight functions, which is not conducive to improving the user experience. Utility Model Content

[0005] To improve the user experience, this application provides a projectable DLP headlight.

[0006] This application provides a projectable DLP headlight, employing the following technical solution: A projectable DLP headlight includes a housing containing an illumination component and a projection device. The housing has a transparent cover on one side of the opening, and an inner plate is detachably connected to the inside of the transparent cover. A mounting bracket is provided between the inner plate and the housing for connection. The projection device includes a mounting box and a lens. The lens is connected to an in-vehicle screen. The mounting box is located at the bottom of the housing, and the lens is located on the side of the mounting box near the inner plate. The inner plate has a through hole one for accommodating the illumination component and a through hole two for accommodating the projection device. The light from the illumination component shines to the outside through the through hole one, and the lens projects to the outside through the through hole two.

[0007] By adopting the above technical solution, under the support of the housing, the built-in plate is connected to the housing through the mounting parts. The transparent cover protects the inside of the housing. The built-in plate supports and fixes the lighting components through the through-holes. The housing supports and fixes the mounting box. The built-in plate cooperates with the mounting box through the second through-hole to support and fix the lens. This reduces the probability of the lighting components shaking and affecting the normal driving of the car, as well as the probability of the lighting components shaking and affecting the structural stability during car operation. It is beneficial to improve the installation stability of the lighting components and the lens. The image inside the lens is projected outward through the second through-hole, so that users do not need additional projection equipment when outdoors. They can watch the image through the car by operating the screen inside the car, which is beneficial to improving the user experience.

[0008] Optionally, the mounting box is connected to the housing on the side away from the lens. The mounting box is provided with several heat sinks, and several bolts are provided on the heat sinks. The bolts pass through the heat sinks and are threaded to the outer wall of the mounting box. An elastic element is provided on the outside of the bolts. One end of the elastic element is fixedly connected to the heat sink and the other end is fixedly connected to the bolt. In its natural state, the elastic element has a tendency to push the heat sinks closer to the mounting box.

[0009] By adopting the above technical solution, the mounting box fixes the heat sink and bolts, the bolts support the elastic element, and the elastic element pushes the heat sink closer to the mounting box. When the heat sink shakes during vehicle operation, the elastic element buffers the shaking of the heat sink, reducing the probability of damage caused by hard contact between the heat sink and the mounting box during shaking. This helps to improve the service life of the heat sink and the mounting box. When the projection device is working, the heat sink dissipates heat from the mounting surface, reducing the probability that overheating of the mounting box will affect the lens performance and projection effect.

[0010] Optionally, the mounting component includes several clamping plates and mounting slots. The clamping plates are arranged circumferentially along the inner plate and fixedly connected to the inner plate. The clamping plates extend towards the cover. The mounting slots are opened on the inner wall of the cover and correspond one-to-one with the clamping plates. The clamping plates are inserted into the mounting slots and fit against the inner wall of the mounting slots.

[0011] By adopting the above technical solution, the mounting slot supports and fixes the card plate, and several card plates and mounting slots cooperate to fix the inner plate, limit the displacement of the inner plate along the circumferential direction, improve the stability of the inner plate installation, and facilitate the disassembly of the inner plate by the operator, which helps to improve the disassembly convenience of the inner plate.

[0012] Optionally, the mounting box is provided with a heat dissipation pipe, and a second heat dissipation fin is provided on the side of the mounting box away from the lens. The heat dissipation pipe is inserted into the second heat dissipation fin, with the air inlet of the heat dissipation pipe facing the first heat dissipation fin and the air outlet facing the inner wall of the cover.

[0013] By adopting the above technical solution, the mounting box supports the heat dissipation pipe and the second heat dissipation fin. The heat dissipation pipe discharges hot air around the mounting box, and the second heat dissipation fin dissipates heat from the mounting box while dissipating heat from the heat dissipation pipe, thereby further accelerating the reduction of the temperature of air inside the heating pipe and reducing the probability that hot air outside the mounting box affects the operation of the mounting box and the lens.

[0014] Optionally, the inner plate is inclined from the outside of the edge of the housing to the inside of the housing at the outer sides of the first through hole and the second through hole.

[0015] By adopting the above technical solution, the inclined surface allows the inner plate to avoid the lens, reducing the probability that the inner plate interferes with the projection of the lens, and reflects the light emitted by the lighting assembly, reducing the probability that the light interferes with the projection area.

[0016] Optionally, a day-shaped daylight lamp is arranged on the inner plate, and the daylight lamp is arranged in a shape of the Chinese character "ri" (meaning sun). The light of the lighting assembly and the light of the lens both pass through the gaps of the daylight lamp to irradiate outwards.

[0017] By adopting the above technical solution, the housing supports and fixes the daylight lamp, avoids the lighting assembly, and reduces the influence on the projection of the lighting assembly and the lens. The daylight lamp improves the recognizability of the vehicle when the vehicle is driving in the daytime, which is beneficial to improving the driving safety of the vehicle.

[0018] Optionally, a reinforcement pipe is threadedly connected to the outer side of the lens, a support rod is arranged on the inner wall of the housing, a fixing ring is sleeved on the support rod, the fixing ring slides along the length direction of the support rod, a cross bar is arranged on the outer side of the reinforcement pipe, in an installed state, the cross bar is opposite to the support rod, and the fixing ring is sleeved on the outer side of the cross bar and is threadedly connected with the cross bar.

[0019] By adopting the above technical solution, the housing supports the support rod, the support rod supports the cross bar through the fixing ring, and the cross bar supports and fixes the reinforcement pipe, so that the reinforcement pipe supports and fixes the lens, reducing the probability of damage caused by hard contact between the lens and the inner plate when the vehicle moves, and further improving the installation stability and working stability of the lens.

[0020] Optionally, the inner plate is provided with a flexible pad on the inner wall of the second through hole, and the flexible pad is located between the inner wall of the second through hole and the outer wall of the lens.

[0021] By adopting the above technical solution, the second through hole contacts and supports the outer wall of the lens through the flexible pad, reducing the probability of damage caused by friction between the inner wall of the second through hole and the outer wall of the lens, which is beneficial to improving the installation stability and service life of the lens.

[0022] In summary, the present application includes at least one of the following beneficial technical effects: 1. Supported by the housing, the built-in plate is connected to the housing via mounting components. The transparent cover protects the inside of the housing. The built-in plate supports and fixes the lighting components through through-hole one. The housing supports and fixes the mounting box. The built-in plate, through through-hole two, cooperates with the mounting box to support and fix the lens. This reduces the probability of the lighting components shaking and affecting the normal driving of the car, as well as the probability of the lighting components shaking and affecting the structural stability during car operation. This helps to improve the installation stability of the lighting components and the lens. The image inside the lens is projected outward through through-hole two, so that users do not need additional projection equipment when outdoors. They can watch the image through the car by operating the screen inside the car, which helps to improve the user experience. 2. The mounting box secures the heat sink and bolts, and the bolts support the elastic element. The elastic element pushes the heat sink closer to the mounting box. When the heat sink shakes during vehicle operation, the elastic element cushions the shaking, reducing the probability of damage caused by hard contact between the heat sink and the mounting box during shaking. This helps to improve the service life of the heat sink and the mounting box. When the projection device is working, the heat sink dissipates heat from the mounting surface, reducing the probability of the mounting box overheating affecting lens performance and projection effect. 3. The mounting slot supports and fixes the card plate. Several card plates and mounting slots work together to fix the inner plate and limit the circumferential displacement of the inner plate, thereby improving the stability of the inner plate installation. At the same time, it facilitates the disassembly of the inner plate by the operator, which helps to improve the convenience of disassembly of the inner plate. Attached Figure Description

[0031] The present application will be further described in detail below with reference to all the accompanying drawings.

[0032] This application discloses a projectable DLP headlight.

[0033] Example 1 Reference Figure 1 A projectable DLP headlight includes a housing 1, which is closed at one end along its length and open at the other end. The housing 1 has an annular groove circumferentially formed at one end of the opening. A transparent cover 4 is installed at the opening of the housing 1. The transparent cover 4 is inserted into the annular groove and fits against the inner wall of the annular groove. The housing 1 supports and fixes the transparent cover 4 through the annular groove.

[0034] Reference Figure 2 and Figure 3 The housing 1 houses a lighting assembly 2 and a projection device 3. A mounting plate is also installed inside the housing 1. Both the lighting assembly 2 and the projection device 3 pass through and are fixedly connected to the mounting plate. The mounting plate is circumferentially fixed to the inner wall of the housing 1. The housing 1 uses the mounting plate to initially secure the lighting assembly 2 and the projection device 3. The user controls the projection device 3 via an operating screen, allowing it to project images. This eliminates the need for additional projection equipment when outdoors, enabling viewing from within a car and enhancing the user experience.

[0035] Reference Figure 2 and Figure 4 The cover 1 has an inner plate 5 installed inside the transparent cover 4. An installation component 6 is installed between the inner plate 5 and the cover 1. The installation component 6 includes multiple clamping plates 61 and installation grooves 62. The multiple installation grooves 62 are arranged circumferentially along the inner wall of the cover 1 and are opened on the outer wall of the annular groove. The multiple clamping plates 61 are arranged circumferentially along the inner plate 5 and correspond one-to-one with the installation grooves 62. The clamping plates 61 are inserted into the installation grooves 62 and fit against the inner wall of the installation grooves 62. The installation grooves 62 accommodate and fix the clamping plates 61, thereby limiting the circumferential displacement of the inner plate 5, which helps to improve the installation stability and disassembly convenience of the inner plate 5.

[0036] Reference Figure 2 and Figure 3, the projection device 3 comprises a lens 32 and a mounting box 31. The mounting box 31 is mounted on a mounting plate, and the lens 32 is mounted on a side of the mounting box 31 close to the inner plate 5. A first through hole 51 and a second through hole 52 are opened on the inner plate 5, and the first through hole 51 and the second through hole 52 are oppositely arranged. In an installed state, the lighting assembly 2 passes through the first through hole 51 and contacts an inner wall of the first through hole 51, and the lens 32 passes through the second through hole 52 and contacts an inner wall of the second through hole 52. The inner plate 5 fixes the lighting assembly 2 through the first through hole 51, and fixes the lens 32 through the second through hole 52, further improving the mounting stability of the housing 1 for the lighting assembly 2 and the lens 32. The lighting assembly 2 comprises a high beam and a low beam, both of which are in the prior art, and will not be described in excessive detail herein.

[0037] Reference Figure 2 , the inner plate 5 is provided with inclined surfaces on the outer sides of the first through hole 51 and the second through hole 52, and the inclined surfaces are inclined from the edge of the inner plate 5 toward the axis direction of the first through hole 51 or the second through hole 52. The inclined surfaces reduce the probability that the inner plate 5 affects the light projected by the lens 32 or emitted by the lighting assembly 2, and the inclined surfaces reflect the light emitted by the lighting assembly 2, reducing the probability that the light interferes with the projection area, which is beneficial to improving the projection effect of the lens 32.

[0038] Reference Figure 2 , a DRL 7 is installed on the inner plate 5 along the outer sides of the first through hole 51 and the second through hole 52. The DRL 7 is arranged in a D-shape and avoids the first through hole 51 and the second through hole 52, reducing the influence on the illumination of the lighting assembly 2 and the projection of the lens 32. The DRL 7 improves the identification of the vehicle during daytime driving, which is beneficial to improving the driving safety of the vehicle in the daytime.

[0039] Reference Figure 3 and Figure 5 , a first heat dissipation fin 311 is installed on a side of the mounting box 31 close to the lighting assembly 2, and the first heat dissipation fin 311 is arranged along the length direction of the mounting box 31. A bolt 312 is installed on the mounting box 31, the bolt 312 passes through the first heat dissipation fin 311 and is slidably connected with the first heat dissipation fin 311 along the length direction of the bolt 312 itself. An elastic member 313 is installed on the bolt 312, one end of the elastic member 313 along the length direction is fixedly connected with the bolt 312, and the other end is fixedly connected with the first heat dissipation fin 311. In a natural state, the elastic member 313 has a tendency to push the first heat dissipation fin 311 toward the mounting box 31. The mounting box 31 fixes and supports the first heat dissipation fin 311 and the bolt 312, and the bolt 312 supports and guides the elastic member 313. When the vehicle is running, the first heat dissipation fin 311 shakes along the length direction of the bolt 312, and the elastic member 313 buffers the shaking of the first heat dissipation fin 311, reducing the probability of wear caused by hard contact between the mounting box 31 and the first heat dissipation fin 311 due to hard contact between the first heat dissipation fin 311 and the mounting box 31, which is beneficial to improving the service life of the mounting box 31 and the first heat dissipation fin 311.

[0040] Reference Figure 3 and Figure 5 A heat sink 315 is installed on the side of the mounting box 31 away from the lens 32. A heat sink 314 is inserted into the heat sink 315. The end of the heat sink 314 away from the heat sink 315 is located between the heat sink 311 and the lighting component 2, and is directly opposite the heat sink 311. The heat sink 314 exhausts the hot air between the mounting box 31 and the lighting component 2, reducing the air temperature between the mounting box 31 and the lighting component 2. At the same time, the heat sink 315 dissipates the heat on the surface of the heat sink 314, reducing the probability that the overheating of the mounting box 31 will affect the performance of the lens 32 and the projection effect.

[0041] The implementation principle of a projectable DLP headlight according to an embodiment of this application is as follows: Under the support of the housing 1, the transparent cover 4 protects the internal structure of the housing 1. The built-in plate 5 supports the lighting component 2 through the through hole 51, reducing the probability that the lighting component 2 will shake and affect the lighting effect of the car during driving. The housing 1 supports and fixes the lens 32 through the through hole 52, improving the installation stability of the lens 32. The heat sink 311 and the heat sink 315 work together to dissipate the heat generated by the mounting box 31 during projection, reducing the probability that the air temperature around the mounting box 31 will be too high and affect the performance of the lens 32 and the projection effect. The user operates the screen inside the car to control the lens 32 to project outward, so that the user does not need to carry an additional projection device when outdoors and can watch the image through the car projection, which is conducive to improving the user experience.

[0042] Example 2 The difference between this embodiment and embodiment 1 is that a reinforcing tube 321 is threadedly connected to the outer side of the lens 32.

[0043] Reference Figure 6 and Figure 7 A support rod 11 is installed on the inner wall of the housing 1, extending radially towards the lens 32. A fixing ring 12 is fitted onto the support rod 11, and the fixing ring 12 is slidably connected to the support rod 11 along its length. A crossbar 322 is installed on the outer side of the reinforcing tube 321, and in the installed state, the crossbar 322 is directly opposite the support rod 11. The housing 1 supports the support rod 11. The operator rotates the fixing ring 12 to make it fit onto the outside of the crossbar 322 and threadedly connect it to the crossbar 322. The support rod 11 supports and fixes the crossbar 322 through the fixing ring 12, and the crossbar 322 supports and fixes the fixing tube, thereby further supporting and fixing the lens 32. This reduces the probability of the lens 32 shaking with the internal plate 5 during vehicle operation, which helps improve the installation stability of the lens 32.

[0044] Reference Figure 6and Figure 7 A flexible pad 53 is provided on the inner wall of the second through hole 52 along the circumferential direction. The second through hole 52 contacts the outer wall of the lens 32 through the flexible pad 53. The flexible pad 53 increases the friction between the second through hole 52 and the outer wall of the lens 32, thereby improving the installation stability between the lens 32 and the inner wall of the second through hole 52. At the same time, it reduces the probability of hard contact between the lens 32 and the inner wall of the second through hole 52, which may cause friction damage, and helps to extend the service life of the lens 32.

[0045] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
