Description

An adjustable vehicle-mounted projector mounting device Technical Field

[0001] This utility model relates to a vehicle-mounted projector fixing device, and more particularly to an adjustable vehicle-mounted projector fixing device. Background Technology

[0002] With the increasing prevalence of automobiles in daily life, they are no longer simply used as a means of transportation. People also use cars as mobile advertising tools and leisure and entertainment venues. For example, advertising information can be projected onto the rear windshield or windows using a car projector. Alternatively, while waiting in the car, office or video information can be projected onto a screen for work or watching videos. In current technology, car projectors are mounted on a fixed device with two fixed rods at a fixed distance. When using the projector, the headrest is removed from the top of the vehicle seat, exposing two mounting slots. The two rods from the projector mounting device are then inserted into these slots. However, each user... The first time you use a car projector, you need to remove the headrest from the top of the vehicle seat, which is very inconvenient. Also, sometimes you need to attach the projector to the rear seat, and sometimes to the front seat. The distance between the two mounting slots on the front seat and the rear seat may differ. Since the distance between the two mounting rods on current car projector mounts is fixed, the mount may not fit both the front and rear seats simultaneously, leading to compatibility issues. Furthermore, the distance between the two mounting slots on the top of the seats may vary between different vehicle models and brands, causing compatibility problems when using the projector mount on different vehicle models and brands. Summary of the Invention

[0003] This utility model provides an adjustable vehicle projector mounting device to solve the problem that the vehicle projector mounting device cannot be well adapted to the seats of different models and brands of vehicles, and that the headrest needs to be removed from the top of the vehicle seat every time the vehicle projector is used.

[0004] According to one aspect of the present invention, an adjustable vehicle-mounted projector mounting device is provided, comprising:

[0005] The first end of the connecting frame is detachably connected to the vehicle-mounted projector.

[0006] A fixing plate is fixedly connected to the second end of the connecting frame. The fixing plate is long and narrow, and at least one end of the fixing plate is provided with a waist-shaped through hole.

[0007] The fixing components consist of two sets, each set being disposed at one end of the fixing plate. Each fixing component includes a fixing mechanism and a first knob, which are disposed on both sides of the fixing plate. The fixing mechanism and the first knob are detachably fixedly connected. At least one set of fixing components can be adjusted in position within the range of the waist-shaped through hole. The fixing mechanism is used to fix the vehicle projector fixing device to the support rod of the car headrest.

[0008] Furthermore, each end of the fixing plate is provided with a waist-shaped through hole, and a set of fixing components is provided at the corresponding position of each waist-shaped through hole. The two sets of fixing components can be adjusted in position within the range of the corresponding waist-shaped through hole.

[0009] Furthermore, one end of the connecting frame is detachably connected to the vehicle-mounted projector via a universal joint. The universal joint is provided with a rotatable shaft, and a support plate is provided on the rotatable shaft. The support plate is rotatably threadedly connected to the rotatable shaft of the universal joint.

[0010] Furthermore, a second knob is provided on the side wall of the universal joint, which is used to control the rotation of the rotatable shaft of the universal joint.

[0011] Furthermore, the fixing mechanism includes a support rod fixing clip, a support rod movable clip, and a rotating base. The first end of the support rod fixing clip is provided with a threaded rod, which passes through the waist-shaped through hole and is threadedly connected to the first knob. The second end of the support rod fixing clip extends out two drive arms, forming a U-shaped opening between the two drive arms. The support rod movable clip is rotatably disposed in the rotating base, and the two drive arms are respectively inserted between the support rod movable clip and the rotating base, and the two drive arms are threadedly connected to the rotating base.

[0012] The support rod movable clip and the U-shaped opening form a through clamping hole, which is used to clamp the headrest support rod.

[0013] Furthermore, a groove is provided on the side of the support rod movable clip near the U-shaped opening.

[0014] Furthermore, a flexible protective pad is provided on the surface of the groove.

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

[0016] When installing the adjustable in-vehicle projector mounting device onto the support rod of the vehicle seat headrest, first insert the support rod into the U-shaped opening of the support rod fixing clip. Then, engage the rotating base with the movable support rod clip with the two drive arms of the support rod fixing clip. By rotating the rotating base, the threads of the two drive arms of the support rod fixing clip are connected to the threads inside the rotating base. During the rotation of the rotating base, the two drive arms of the support rod fixing clip clamp the movable support rod clip, preventing the movable support rod clip from rotating. At the same time, the rotating base will push the movable support rod clip forward until the support rod fixing clip and the movable support rod clip together clamp the headrest support rod. The user can adjust the position of the fixing mechanism on the support rod by loosening the rotating base, and then tighten the rotating base.

[0017] Connect the vehicle projector to the vehicle projector mounting device via threads. Pass the threaded rod on the support rod fixing clip through the waist-shaped through hole on the fixing plate. Connect the first knob to the threaded rod on the support rod fixing clip via threads and fix the fixing plate, thereby fixing the entire vehicle projector mounting device.

[0018] The spacing between the two support rods on the headrests of different vehicle models and brands varies. This invention fixes two fixing mechanisms to the two support rods, and then uses the waist-shaped through holes on the fixing plate to accommodate support rods with different spacings. At the same time, the vehicle projector can be fixed without removing the vehicle headrest. Therefore, the adjustable vehicle projector fixing device of this invention has high adaptability and can be used in any seat on different models and brands of vehicles. It is also easy to install without removing the vehicle headrest. Attached Figure Description

[0029] In this utility model, unless otherwise stated, directional terms such as "upper," "lower," "top," and "bottom" are generally used in relation to the direction shown in the accompanying drawings, or in relation to the vertical, perpendicular, or gravitational direction of the component itself; similarly, for ease of understanding and description, "inner" and "outer" refer to the inner and outer contours of each component itself, but the above directional terms are not used to limit this utility model.

[0030] According to one aspect of the present invention, an adjustable vehicle projector mounting device is provided, which can be adapted to car seat headrests with different spacing, as shown in Figure 1, including:

[0031] Connector 1, the first end of connector 1 is detachably connected to the vehicle-mounted projector;

[0032] Fixed plate 2 is fixedly connected to the second end of connecting frame 1. Fixed plate 2 is long strip-shaped and has at least one end of fixed plate 2 with a waist-shaped through hole 21.

[0033] The fixing components consist of two sets, which are respectively set at both ends of the fixing plate 2. The fixing components include a fixing mechanism 3 and a first knob 4. The fixing mechanism 3 and the first knob 4 are set on both sides of the fixing plate 2. The fixing mechanism 3 and the first knob 4 are detachably fixedly connected. At least one set of fixing components can be adjusted in position within the range of the waist-shaped through hole 21. The fixing mechanism 3 is used to fix the vehicle projector fixing device to the support rod of the car headrest.

[0034] Please refer to Figures 5 and 6. The fixing mechanism 3 includes a support rod fixing clip 33, a support rod movable clip 32, and a rotating base 31. The first end of the support rod fixing clip 33 is provided with a threaded rod, which passes through the waist-shaped through hole 21 and is threadedly connected to the first knob 4. The second end of the support rod fixing clip 33 extends out two drive arms 331, forming a U-shaped opening between the two drive arms 331. The support rod movable clip 32 is rotatably disposed in the rotating base 31. The two drive arms 331 are respectively inserted between the support rod movable clip 32 and the rotating base 31, and the two drive arms 331 are threadedly connected to the rotating base 31.

[0035] Among them, a through clamping hole 34 is formed between the movable support rod clip 32 and the U-shaped opening, and the clamping hole 34 is used to clamp the support rod of the headrest.

[0036] When the adjustable vehicle projector mounting device needs to be installed on the support rod of the vehicle seat headrest, first insert the support rod into the U-shaped opening of the support rod fixing clip 33, and then engage the rotating base 31 with the support rod movable clip 32 and the two drive arms 331 of the support rod fixing clip 33. By rotating the rotating base 31, the two drive arms 331 of the support rod fixing clip 33 are threadedly connected to the threads inside the rotating base 31. During the rotation of the rotating base 31, the two drive arms 331 of the support rod fixing clip 33 clamp the support rod movable clip 32 to prevent the support rod movable clip 32 from rotating. At the same time, the rotating base 31 will push the support rod movable clip 32 forward until the support rod fixing clip 33 and the support rod movable clip 32 together clamp the headrest support rod. The user can adjust the position of the fixing mechanism 3 on the support rod by loosening the rotating base 31, and then tighten the rotating base 31.

[0037] The vehicle projector is connected to the vehicle projector mounting device by threads. The threaded rod on the support rod fixing clip 33 is passed through the waist-shaped through hole 21 on the fixing plate 2. The first knob 4 is connected to the threaded rod on the support rod fixing clip 33 by threads, and the fixing plate 2 is fixed, thereby fixing the entire vehicle projector mounting device.

[0038] The spacing between the two support rods on the headrests of different vehicle models and brands varies. This invention fixes two fixing mechanisms 3 to the two support rods, and then uses the waist-shaped through hole 21 on the fixing plate 2 to adapt to support rods with different spacings. At the same time, the vehicle projector can be fixed without removing the vehicle headrest. Therefore, the adjustable vehicle projector fixing device of this invention has high adaptability and can be used in any seat of different models and brands of vehicles. It is also easy to install without removing the vehicle headrest.

[0039] In one embodiment, as shown in Figures 1 to 4, a waist-shaped through hole 21 is provided at both ends of the fixing plate 2, and a set of fixing components is provided at the corresponding position of each waist-shaped through hole 21. The two sets of fixing components can be adjusted in position within the range of the corresponding waist-shaped through hole 21.

[0040] By setting two waist-shaped through holes 21, the adjustment distance of the projector mounting device can be further expanded.

[0041] In one embodiment, as shown in Figures 2-4, one end of the connecting frame 1 is detachably connected to the vehicle projector via a universal joint 5. The universal joint 5 is detachably fixedly connected to the connecting frame 1 via a third knob 7. The universal joint 5 is provided with a rotatable shaft 51, and a support plate 6 is provided on the rotatable shaft 51. The support plate 6 is rotatably threadedly connected to the rotatable shaft 51 of the universal joint 5.

[0042] The support plate 6 can be made of metal or rigid plastic. If metal, aluminum or aluminum alloy is preferred because of their low density, resulting in a lightweight and inexpensive product. If rigid plastic is used, ABS, PC, PA, PP, etc., are preferred. A combination of materials can also be used; for example, the internal material could be rigid plastic like ABS, covered with a soft material such as TPE. This soft outer layer improves the user's feel and overall experience. The support plate 6 can utilize a variety of materials, with a rigid plastic internally and a soft outer layer.

[0043] Of course, the above-mentioned preferred materials do not constitute a limitation on the choice of materials. Any material that can support the vehicle-mounted projector is within the material selection range of this utility model.

[0044] During vehicle movement, bumps and vibrations can cause the vehicle-mounted projector to shake. Repeated or severe shaking can damage the threaded connection between the rotatable shaft 51 of the universal joint 5 and the vehicle-mounted projector. To prevent damage to this connection during vehicle movement, a support plate 6 is rotatably threaded onto the rotatable shaft 51 of the universal joint 5. After the vehicle-mounted projector is installed on the rotatable shaft 51, the support plate 6 is rotated in the opposite direction until it presses firmly against the projector. During vehicle movement, the support plate 6 supports the projector, preventing it from shaking relative to the rotatable shaft 51 of the universal joint 5. This prevents damage to the threaded connection between the projector and the rotatable shaft 51 during vehicle movement, thus extending the service life of the vehicle-mounted projector and its mounting device.

[0045] In one embodiment, a second knob 52 is provided on the side wall of the universal joint 5, and the second knob 52 is used to control the rotation of the rotatable shaft 51 of the universal joint 5.

[0046] During use, the vehicle projector needs to be adjusted to a certain angle. Loosen the second knob 52 and rotate the vehicle projector to fix the rotatable shaft 51 of the universal joint 5 to a suitable angle and position. Then tighten the second knob 52 to fix the rotatable shaft 51 of the universal joint 5, thereby realizing the adjustment of the angle and position of the vehicle projector.

[0047] In one embodiment, the support rod movable latch 32 has a groove on the side near the U-shaped opening. A flexible protective pad 321 is provided on the surface of the groove, and the protective pad 321 is attached to the surface of the groove by double-sided tape or adhesive.

[0048] A groove is provided on the side of the movable clip 32 of the support rod near the U-shaped opening. The clamping hole 34 formed by the U-shaped opening of the groove is similar in shape to the support rod, which can increase the contact area between the clamping hole 34 and the support rod, increase the clamping force of the support rod and the fixing mechanism 3, and prevent the vehicle projector fixing device from loosening during bumpy conditions.

[0049] The protective pad 321 can be made of either rigid plastic or flexible material. Rigid plastics are preferably ABS, PC, PA, PP, etc., while flexible materials include TPE, rubber, or silicone. Covering the outer surface with a soft material improves the user's feel and overall experience. The support plate 6 is made of a variety of materials, with a rigid plastic interior and a soft material exterior.
