[0001] This utility model relates to the field of vehicle accessories, specifically to an adjustable projection device for installation on a vehicle. Background Technology

[0002] To enhance the visual ambiance of vehicles and provide functional lighting assistance for getting in and out, while also elevating the sense of prestige or luxury, some commercially available vehicles are equipped with projection lights. When activated, these lights project images or text onto the ground or a suitable location on the vehicle body. For example, a projection light can be installed in a suitable location on the vehicle and connected to its power source. When a door is opened, a sensor automatically activates the projection light, projecting images or text onto the ground, thus enhancing the visual appeal and providing supplementary lighting at night or in low-light environments. The images or text can be the vehicle brand's logo, trademark, or any combination of patterns and text.

[0003] Conventional projector lights are designed and developed based on different car models and sizes. This means that a specific type of projector light can only be installed on the corresponding car model in order to achieve accurate focus of the projected image. Furthermore, the size, direction, and angle of the projected image are fixed and cannot be adjusted according to personal preferences. Utility Model Content

[0004] The purpose of this invention is to provide a projection device that allows the direction, angle, and size of the projected image to be adjusted according to personal preference, particularly a universal adjustable projection device for installation in various vehicles.

[0005] This utility model provides an adjustable projection device for installation in a vehicle, comprising a bracket assembly and a projection lamp assembly. The bracket assembly includes: a fixed bracket for fixing to the vehicle; a movable bracket having a pair of cantilever arms on opposite sides, the movable bracket being fixed to a first side of the fixed bracket and the pair of cantilever arms extending through a hollow portion of the fixed bracket to a second side of the fixed bracket, the ends of the pair of cantilever arms each having a bushing; an adjusting screw rotatably disposed on the movable bracket, the threaded portion of the adjusting screw extending out of the second side of the fixed bracket; a rubber ring fitted onto the adjusting screw and located between the screw head of the adjusting screw and the movable bracket; and a screw clip disposed on the threaded portion of the adjusting screw; and a projection lamp assembly comprising: a housing having rotating shafts on opposite sides, the rotating shafts rotatably engaging with the bushings, an adjusting screw hole on one side of the housing, the adjusting screw hole engaging with the adjusting screw; and a lens assembly disposed inside the housing for projecting an image out of the housing.

[0006] In one embodiment of this utility model, the movable bracket may have a plate body with a central hole and through holes and arc-shaped slots located on opposite sides of the central hole. The cantilever extends from the plate body. Fixing screws pass through the through holes and arc-shaped slots and are then locked into screw holes provided in the fixed bracket. Accordingly, after the projection lamp assembly is installed on the cantilever, the movable bracket can be rotated along the direction of the arc-shaped slots while the fixing screws are loosened to adjust the position of the projection lamp assembly. Then, the fixing screws are tightened to fix the projection lamp assembly in that position.

[0007] In one embodiment of this utility model, it may further include: a cap with a straight slot; wherein the adjusting screw passes through the straight slot and the center hole and is screwed into the adjusting screw hole. Accordingly, with the adjusting screw loosened, the movable bracket can be moved along the extension direction of the straight slot to adjust the position of the projection lamp assembly, and then the adjusting screw can be tightened to fix the projection lamp assembly in that position.

[0008] Preferably, a slot can be formed on the upper side of the cantilever, and the bushing is disposed within the slot. This facilitates the installation of the bushing onto the cantilever.

[0009] In one embodiment of the present invention, the projection lamp assembly further includes: a lamp board assembly disposed within the housing, the lamp board assembly including a circuit board and a light-emitting element electrically connected to the circuit board, the light generated by the light-emitting element projecting the image of the image element out of the housing through the lens assembly; and a heat sink connected to the housing for absorbing and dissipating the heat generated by the lamp board assembly.

[0010] Preferably, a plurality of fins are formed on the outer surface of the heat sink. This allows for efficient and rapid heat transfer from the lamp panel assembly to the fins for dissipation.

[0011] Compared with the prior art, the beneficial effect of this utility model is that when the adjusting screw is rotated, the projection lamp assembly can be controlled to rotate relative to the cantilever, thereby adjusting the direction and angle of the projected image of the projection lamp assembly.

[0056] To facilitate understanding of this utility model, it will be described in detail below with reference to the accompanying drawings and embodiments. The drawings show some, but not all, embodiments of this utility model. This utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without inventive effort are within the scope of protection of this utility model.

[0057] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0058] like Figure 1 and Figure 2 As shown, the adjustable projection device provided by this utility model is suitable for installation at various appropriate locations such as the bottom of the door of a vehicle 40, the rearview mirror, etc., and is electrically connected to the controller 30 via a power cord 2031. It works with the sensors and circuitry in the controller 30 to automatically project an image onto the ground through the projection port 401 provided on the vehicle 40 when the door is opened, and interrupts the projection when the door is closed. The adjustable projection device includes a bracket assembly 10 and a projection lamp assembly 20. The bracket assembly 10 further includes a fixed bracket 101 and a movable bracket 102; wherein the fixed bracket 101 is a component for fixing to the vehicle 40 (e.g., a fixed bracket 101 for fixing to the vehicle 40). Figure 3 As shown), the main body of the fixing bracket 101 has a hollow portion 1011 extending through its opposite sides (i.e., the first side and the second side). Ears 1012 are formed on opposite sides below the main body. Each ear 1012 has a through hole 1013. That is, the ear 1012 is located on opposite sides below the second side of the fixing bracket 101. The through hole 1013 is used for screws (not shown) to pass through to fix the fixing bracket 101 to the vehicle 40; that is, Figure 1 and Figure 2 The vehicle 40 shown can actually be, for example, the bottom of a car door. The bottom of the car door is provided with a screw hole. After the screw passes through the through hole 1013, it is locked into the screw hole at the bottom of the car door to fix the fixing bracket 101 to the vehicle 40. Furthermore, screw holes 1014 and 1015 are provided on opposite sides of the hollow part 1011 for installing the movable bracket 102, which will be described in detail later.

[0059] like Figures 1 to 3As shown, the movable support 102 has a plate 1021, with a central hole 10211 penetrating its two opposite sides (i.e., the first side and the second side), and through holes 10212 and arc-shaped slots 10213 formed on opposite sides of the central hole 10211, respectively. A pair of cantilever arms 1022 are horizontally extended on opposite sides of the second side of the plate 1021 (e.g., the pair of cantilever arms 1022 are fixed to the second side of the plate 1021 by welding). A slot 10221 is formed on the upper side of the cantilever arm 1022 near its free end (e.g., a slot is formed on the upper side of the cantilever arm 1022 near its free end). Figure 3 As shown, the opening of the slot 10221 has a relatively small width, and the width extends from the opening to the inside to form a relatively large width, so that the bushing 102 can be fitted into the slot 10221 in a fitting manner; that is, the bushing 102 can be pressed into the slot 10221 through the opening to complete the fitting. The bushing 102 is used to cooperate with the rotating shafts 2011 on opposite sides of the housing 201 of the projection lamp assembly 20, so that the projection lamp assembly 20 can rotate around the rotating shafts 2011.

[0060] The movable bracket 102 is used to fix it to the first side of the fixed bracket 101. Specifically, after the cantilever 1022 of the movable bracket 102 passes through the hollow part 1011 of the fixed bracket 101 and the plate 1021 is placed against the first side of the fixed bracket 101, the fixing screw 1025 passes through the washer 10251 and the arc-shaped slot 10213 on the plate 1021 and is locked into the screw hole 1015 of the fixed bracket 101, and the fixing screw 1026 passes through the hole 10212 on the plate 1021 and is locked into the screw hole 1014 of the fixed bracket 101. After the projection lamp assembly 20 is installed on the cantilever 1022, the movable bracket 102 can be rotated along the direction of the arc-shaped slot 10213 with the fixing screws 1025 and 1026 loosened to adjust the position of the projection lamp assembly 20 (e.g., horizontal or tilted). Then the fixing screws 1025 and 1026 are tightened to fix the projection lamp assembly 20 in the adjusted position.

[0061] The bracket assembly 10 of this utility model also includes an adjusting screw 1024, a rubber ring 10241, a screw clip 10242, and a cap 10214; wherein, as Figure 2 and Figure 5As shown, the cap 10214 can be formed as a circular or other shaped plate, with a straight slot 10215 formed thereon. After the adjusting screw 1024 passes through the rubber ring 10241, the straight slot 10215, and the center hole 10211 of the movable bracket 102, the screw clip 10242 is engaged with the appropriate position of the threaded portion of the adjusting screw 1024 to act as a blocking element for controlling the stroke of the adjusting screw 1024, and to position the rubber ring 10241 between the screw head of the adjusting screw 1024 and the movable bracket 102. The screw clip 10242 is shaped like a washer, with a plurality of radial grooves forming a plurality of annularly distributed spring pieces around its central hole. Therefore, when the adjusting screw 1024 passes through the hole of the screw clip 10242, it can pass through the elastic spring pieces and be locked at any position on the threaded portion by the spring pieces, thereby acting as a blocking element for controlling the stroke of the adjusting screw 1024.

[0062] like Figure 2 As shown, the projection lamp assembly 20 is connected to the movable bracket 102 and can rotate relative to the movable bracket 102 to adjust the direction, angle, and size of the projected image. Specifically, the projection lamp assembly 20 includes a housing 201, a lens assembly 202, a lamp panel assembly 203, and a heat sink 207; wherein, the housing 201 is a hollow shell with a projection hole at one end (located in...). Figure 3 The lower end of the housing 201 (not shown) has a lens 204 and a sealing ring 205 installed at the projection hole. The perforated lower cover 206 is then locked to the housing 201 to secure the lens 204 and sealing ring 205, preventing moisture and humidity from entering the housing 201. The lens assembly 202 and lamp panel assembly 203 are assembled inside the housing 201 from the upper end, and then the heat sink 207 is covered and fixed to the upper end of the housing 201. Rotating shafts are located on opposite sides of the exterior of the housing 201. 2011, an adjustment screw hole 2012 is provided on the other side of the outer shell 201. The rotating shaft 2011 is fitted to the bushing 1023 on the cantilever 1022, so that the outer shell 201 can rotate relative to the cantilever 1022. The threaded parts of the adjustment screw hole 2012 and the adjustment screw 1024 are screwed together. When the adjustment screw 1024 rotates into the adjustment screw hole 2012, causing the screw clip 10242 to abut against the plate 1021, it can prevent the adjustment screw 1024 from being locked in further.

[0063] The lens assembly 202 includes a modularly packaged lens and an image element (not shown). The image element is a film with patterns, text, etc., and is positioned on the optical path of the lens. The lamp board assembly 203 includes a circuit board and a light-emitting element (e.g., LED, not shown) electrically connected to the circuit board. The circuit board is connected to a power line 2031 (e.g., ...). Figure 4(As shown) Electrically connected to the vehicle's power supply, when powered on, the light-emitting element projects light through the lens assembly 202 to project the image of the image element onto the housing 201. The lens assembly 203 and the lamp panel assembly 203 are prior art and not technical features claimed in this case, therefore further detailed descriptions are omitted.

[0064] The heat sink 207 is formed with a plurality of fins on its outer surface and perforations at the four corners. When the lens assembly 202 and the lamp panel assembly 203 are installed in the housing 201 and the heat sink 207 is covered on the housing 201, the heat sink 207 and the housing 201 are fixed together by using fixing screws 208 through the perforations and locking them into the screw holes of the housing 201. The heat generated when the light-emitting element of the lamp panel assembly 203 emits light can be transferred to the heat sink 207 and dissipated by the plurality of fins formed thereon.

[0065] like Figure 5 As shown, the projection device of this utility model is installed in the vehicle 40. The direction, angle and size of the projected image of the projection lamp assembly 20 can be adjusted by operating the adjustment screw 1024. Specifically, for example, when the adjustment screw 1024 is rotated counterclockwise, the adjustment screw 1024 will pull the projection lamp assembly 20 to swing closer to the adjustment screw 1024. Conversely, when the adjustment screw 1024 is rotated clockwise, the adjustment screw 1024 will push the projection lamp assembly 20 to swing away from the adjustment screw 1024, thereby adjusting the direction and angle of the projection of the projection lamp assembly 20. During the rotation of the adjustment screw 1024, the elastic rubber ring 10241 is subjected to a slight pressure effect by the screw head of the adjustment screw 1024, or the rebound after being released, thereby slightly adjusting the swing angle of the projection lamp assembly 20. By adjusting the direction and angle of the projection lamp assembly 20, the size of the projected image can be adjusted simultaneously. That is, when the projected image is perpendicular to the ground, the image is at its smallest; the smaller the angle between the emitted light from the projection lamp assembly and the ground (i.e., the larger the angle with the vertical), the larger the image projected onto the ground. Therefore, the projection device of this invention is suitable for installation in any type of vehicle and provides convenient adjustment of the direction, angle, and size of the projected image.

[0066] The embodiments described above are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various changes and modifications without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
