Description

Technical Field

[0001] The invention relates to the technical field of projector bracket devices, and in particular to a double-arm projector bracket structure. Background Art

[0002] With the development of multimedia technology and display technology, projectors have been widely used in many fields such as home entertainment, business meetings, education and training. In order to better adapt to various usage scenarios, the design of projector brackets has become particularly important. Existing projector brackets mainly include fixed brackets, single-arm adjustable brackets and other types, each of which has some limitations.

[0003] Desktop projectors are generally used with a single-arm adjustable bracket. For example, a utility model patent with a Chinese announcement number of CN219414108U discloses a "projector", which includes a projector, a bracket rotatably connected to the main body, and a base. The projector is rotatably connected to the bracket, and its angle is adjusted by rotating the projector, but this bracket cannot adjust the height of the projector; there is also a bracket in the prior art in which both ends are rotatably connected to the projector and the base respectively. This projector can be raised by rotating the bracket, but the projection angle of the projector and the projection distance between the projector and the projection surface will also change, so it is necessary to readjust the angle or focal length of the projector, resulting in cumbersome operation steps.

[0004] In view of this, the existing technology still needs to be improved and developed. Summary of the invention

[0005] In view of the above-mentioned deficiencies in the prior art, an object of the present invention is to provide a dual-arm projector bracket structure, aiming to solve the problem that the existing projector adopts a single-arm bracket, which is inconvenient to adjust the height and has complicated operating steps.

[0047] In the prior art, desktop projectors are fixed in a fixed manner or fixed with a single-arm adjustable bracket. The fixed bracket is generally fixed on a desktop, wall or ceiling. Once this fixing method is determined, it is difficult to adjust. Although this structure is simple and low in cost, it is very inconvenient when the position and distance of the projector need to be changed, which limits the flexibility of the projector when used. Compared with the fixed bracket, the single-arm adjustable bracket can have more adjustment freedom, allowing the user to adjust the position of the projector within a certain range. However, when adjusting the height of the projector, the single-arm design will change the distance between the projector and the projection surface, or change the angle of the projector, so that fine-tuning needs to be continued, and the steps are relatively cumbersome. At the same time, the single-arm adjustable bracket is prone to shaking when carrying a heavy load, affecting the projection effect.

[0048] In view of the shortcomings of the prior art, this embodiment provides a dual-arm projector bracket structure, which can be specifically referred to as follows:

[0049] As attached Figure 1 , Attachment Figure 2 and attached Figure 3 As shown, a double-arm projector bracket structure includes a projector body 1, two connecting parts 2 and two U-shaped brackets 3. The projector body 1 can be in a rectangular parallelepiped shape or a spherical shape. A connecting part 2 is rotatably provided on both sides of the projector body 1. The two connecting parts 2 are symmetrically arranged to ensure the stability of the projector body 1 when supporting. The connection direction of the two connecting parts 2 is perpendicular to the projection direction of the projector body 1 to avoid the connection parts 2 affecting the projection; a U-shaped bracket 3 is rotatably provided at both ends of the connecting part 2 parallel to the projection direction of the projector body 1, and the two ends of the U-shaped bracket 3 are respectively rotated with the two connecting parts 2, and the two U-shaped brackets 3 are respectively located at the two ends of the connecting part 2, and the middle position of the connecting part 2 is parallel to the projection direction of the projector body 1. The projector body 1 rotates; through the middle position of the connecting part 2 and the rotation of the projector body 1, the two ends of the connecting part 2 are respectively provided with U-shaped brackets 3, which can realize the independent rotation of the projector body 1 and the two U-shaped brackets 3, and avoid the influence of each other's rotation on the adjacent parts. At the same time, through the synchronous movement of the two U-shaped brackets 3 towards or away from each other, the up and down adjustment of the projector body 1 can be realized without changing the front and back position of the projector body 1. Not only is the operation simple, but also the angle of the projector body 1 will not be changed, and the projection height can be quickly adjusted; at the same time, the design of the double U-shaped brackets 3 significantly enhances the overall rigidity of the brackets, and can maintain good stability even under high load conditions, avoiding the phenomenon of picture jitter.

[0050] In this embodiment, two U-shaped brackets 3 are rotatably arranged on two connecting parts 2, and the two U-shaped brackets 3 are both located at the bottom of the projector body 1, and a limiting component is arranged inside the connecting part 2 to limit the rotation angle of the projector body 1 to prevent the two U-shaped brackets 3 from rotating too much or rotating to the top of the projector body 1, thereby failing to effectively support the projector body 1 and failing to adjust the angle of the projector body 1.

[0051] Furthermore, the U-shaped bracket 3 is made of high-strength materials (such as aluminum alloy, carbon fiber), and the rigidity and stability of the overall structure are ensured by optimized mechanical design. A rubber base plate can be provided at the bottom of each U-shaped bracket 3 to absorb vibration and reduce shaking during operation.

[0052] In this embodiment, as shown in the attached Figure 3 and attached Figure 4 As shown, the connecting part 2 includes a rotating member 21, a spacer block 22 and two rotating parts; the rotating member 21 is arranged on one side of the projector body 1, and a spacer block 22 is arranged on the side of the rotating member 21 close to the projector body 1, and the spacer block 22 is located in the middle position of the rotating member 21, and the spacer block 22 is rotationally matched with the projector body 1, so that the rotating member 21 is also rotationally matched with the projector body 1, and under the action of the spacer block 22, the rotating member 21 and the side wall of the projector body 1 are arranged at intervals; rotating parts are respectively arranged at both ends of the rotating member 21, and the two rotating parts are located at both ends of the spacer block 22 and are symmetrically arranged, and the two ends of the same side of the two U-shaped brackets 3 are respectively rotatably connected with the two rotating parts;

[0053] By rotatably connecting the spacer block 22 to the projector body 1 and rotatably connecting the two rotating parts of the rotating member 21 to the ends of the two U-shaped brackets 3 respectively, the projector body 1 and the two U-shaped brackets 3 can be rotated separately, that is, the projection angle can be adjusted by rotating the projector body 1; the U-shaped bracket 3 at the front or rear end of the projector body 1 can be rotated separately, and the angle adjustment of the projector body 1 can be achieved, that is, the projection angle can be adjusted, which provides a variety of adjustment methods for the projector body 1 and also provides diversity for the support of the projector to be suitable for different support environments; further, the two U-shaped brackets 3 rotate synchronously toward or away from each other, so as to adjust the height of the projector body 1. Without changing the distance between the projector body 1 and the projection surface, the height of the projector body 1 can be changed, thereby avoiding the problem of adjusting the projection angle of the projector body 1, thereby improving the practicality and convenience of the bracket structure.

[0054] In this embodiment, a damper is provided at the position where the connection part 2 and the U-shaped bracket 3 rotate. The damper is a prior art. The damper can prevent the U-shaped bracket 3 from rotating randomly and failing to effectively support the projector body 1.

[0055] In this embodiment, as shown in the attached Figure 4 and attached Figure 5 As shown, the rotating part includes an annular protrusion 23, which is arranged on one side of the rotating member 21 close to the U-shaped bracket 3, and the annular protrusion 23 protrudes from the surface of the rotating member 21. A rotating groove 31 is respectively arranged on both sides of the U-shaped bracket 3 close to the rotating part, and the annular protrusion 23 is rotatably arranged in the rotating groove 31, thereby realizing the rotation effect between the U-shaped bracket 3 and the rotating member 21.

[0056] Furthermore, a damper is disposed inside the rotation groove 31 , and the damper cooperates with the annular protrusion 23 to increase the resistance between the rotation groove 31 and the annular protrusion 23 .

[0057] Furthermore, the connecting portion 2 and the U-shaped bracket 3 can form an integral module, so that the connection portion 2 can be easily installed and removed from the projector body 1, and the subsequent maintenance and replacement can be facilitated.

[0058] In this embodiment, as shown in the attached Figure 5 As shown, the rotating member 21 is provided with a first connecting hole 211 at both ends along the projection direction, the first connecting hole 211 is coaxially arranged with the annular protrusion 23, and a second connecting hole 32 is provided inside the rotating groove 31, the second connecting hole 32 can be a threaded hole, and the first connecting hole 211 and the second connecting hole 32 are connected by a screw, the big head end of the screw is supported on the side wall of the rotating member 21, and the other end cooperates with the second connecting hole 32, so that the rotating member 21 is connected to the U-shaped bracket 3.

[0059] Furthermore, a rubber pad is provided between the big head end of the screw and the side wall of the rotating member 21 .

[0060] Furthermore, the diameter of the screw is smaller than the diameter of the first connecting hole 211 to avoid friction with the screw when the U-shaped bracket 3 rotates, thereby driving the screw to rotate and causing the connection between the rotating member 21 and the U-shaped bracket 3 to loosen; when the U-shaped bracket 3 rotates, the screw will also rotate with the U-shaped bracket 3, and a rubber pad is arranged between the big head end of the screw and the rotating member 21 to reduce the force between the screw and the rotating member 21, so that the screw can rotate relative to the rotating member 21.

[0061] In this embodiment, the big head end of the screw is located on the side of the rotating part 21 away from the U-shaped bracket 3. A cover plate 4 is provided on the side of the rotating part 21 away from the U-shaped bracket 3. The cover plate 4 is sleeved on the rotating part 21 and is used to cover the screw and seal the screw and the first connecting hole 211, thereby preventing external debris from affecting the rotation of the U-shaped bracket 3 and the screw.

[0062] Furthermore, a plurality of slots are provided on one side of the rotating member 21 close to the U-shaped bracket 3, and a plurality of buckles are provided on one side of the cover plate 4. The buckles correspond to the slots one by one and engage with each other, thereby realizing the connection between the cover plate 4 and the rotating member 21. At the same time, the setting of the cover plate 4 can also improve the aesthetics between the projector body 1 and the bracket structure.

[0063] In this embodiment, as shown in the attached Figure 5 and attached Figure 7 As shown, a limit block 24 (i.e., the limit assembly mentioned above) is provided on the inner wall of the annular protrusion 23, a limit groove 33 is provided inside the rotating groove 31, the limit block 24 cooperates with the limit groove 33, the limit groove 33 is arranged in a fan shape, and the limit block 24 can rotate in the limit groove 33; through the action of the limit block 24, the rotation angle of the U-shaped bracket 3 relative to the rotating member 21 can be limited.

[0064] By changing the size of the limiting block 24 or the size of the limiting groove 33 , the rotation angle of the U-shaped bracket 3 can be adjusted to achieve adjustment of the angle or height of the projector body 1 .

[0065] In this embodiment, as shown in the attached Figure 5 and attached Figure 7 As shown, a protrusion 25 is provided on one side of the limit block 24 close to the limit groove 33. The protrusion 25 is circular and can be made of a deformable material such as rubber. A plurality of grooves 34 are evenly distributed on the surface circumference of the limit groove 33, and the protrusion 25 cooperates with the grooves 34.

[0066] By cooperating with the protrusion 25 and the groove 34, the stability of the rotating member 21 and the U-shaped bracket 3 can be further enhanced; at the same time, by evenly distributing multiple grooves 34 on the circumference of the limiting groove 33, the user can judge the angle between the U-shaped bracket 3 and the rotating member 21 according to the force exerted by the protrusion 25 on the groove 34 when rotating, so as to facilitate the adjustment of the angle and height of the projector body 1.

[0067] Furthermore, the top of the U-shaped bracket 3 and both ends of the rotating part 21 are circular surfaces. An angle scale can be set on the circular surface of the U-shaped bracket 3, and a standard line is set on the circular surface of the rotating part 21. The angle of the U-shaped bracket 3 can be read through the standard line, thereby facilitating the adjustment of the angle and height of the projector body 1.

[0068] In this embodiment, as shown in the attached Figure 4 and attached Figure 6As shown, mounting holes are provided on both sides of the projector body 1, and a fixing member 5 is provided inside the projector body 1, and a mounting tube 6 is provided on one side of the fixing member 5. The fixing frame is supported against the inner wall of the projector body 1, and the mounting tube 6 is rotatably set in the mounting hole and protrudes from the outer surface of the projector body 1. The spacer block 22 cooperates with the mounting tube 6 and is connected to each other, so that the spacer block 22 and the rotating member 21 are rotatably set on the projector body 1.

[0069] Specifically, the mounting tube 6 is rotatably arranged in the mounting hole, one side of the mounting tube 6 is connected to a fixing part 5 supported on the inner wall of the projector body 1, and the other end is connected to a spacer block 22 supported on the outer surface of the projector body 1; the mounting tube 6 can be rotatably matched with the projector body 1 through a damper to increase the resistance to the rotation of the projector body 1, and the resistance is greater than the resistance of the damper between the U-shaped bracket 3 and the rotating part 21, thereby effectively preventing the rotating part 21 and the mounting tube 6 from rotating relative to the projector body 1 when the U-shaped bracket 3 rotates.

[0070] In this embodiment, as shown in the attached Figure 5 and attached Figure 6 As shown, a positioning surface 61 is provided at one end of the mounting tube 6 away from the fixing frame, and the positioning surfaces 61 include two, which are respectively located on the upper and lower sides of the mounting tube 6, and a first slot hole 221 is provided inside the spacer block 22, and the first slot hole 221 is used to wrap the mounting tube 6; a mating surface 222 is provided on the inner wall of the first slot hole 221, and the mating surface 222 is matched with the positioning surface 61, so as to realize the positioning and connection of the spacer block 22 and the mounting tube 6.

[0071] By providing a positioning surface 61 on the installation tube 6 and a matching surface 222 in the first slot 221, relative sliding of the spacer block 22 and the installation tube 6 can be achieved, and when one of them rotates, the other can be driven to rotate to avoid relative rotation between the two.

[0072] In this embodiment, a countersunk hole is provided inside the spacer block 22 , and a third mounting hole is provided inside the mounting tube 6 . The countersunk hole and the third mounting hole are connected by screws, so that the rotating member 21 is connected to the mounting tube 6 .

[0073] In this embodiment, gaskets 7 are provided inside the two ends of the mounting tube 6, and the two gaskets 7 are respectively located on the inner wall and the outer surface of the projector body 1, that is, the two gaskets 7 are respectively located on the inner and outer sides of the projector body 1, and are supported on the side wall of the projector body 1 through the action of the fixing member 5 and the spacer block 22; the gasket 7 is a rubber gasket 7; the two gaskets 7 on the mounting tube 6 can also increase the friction between the rotating member 21 and the projector body 1, thereby increasing the damping between the projector and the rotating member 21, and preventing the projector body 1 from tilting or rotating during operation.

[0074] During operation, the projector body 1 emits sound through the speaker. When the sound is too loud, the projector body 1 will vibrate to a certain extent. The gasket 7 can reduce the vibration acting on the mounting tube 6 and the spacer block 22, thereby preventing the U-shaped bracket 3 and the projector body 1 from rotating. At the same time, the screw between the first connecting hole 211 and the second connecting hole 32 is connected to the rotating member 21 through a rubber pad, and the rubber pad can further reduce the vibration force of the projector body 1, thereby improving the stability of the bracket structure.

[0075] Furthermore, a motor is provided inside the rotating member 21, and the output shaft of the motor can be connected to the U-shaped bracket 3. The U-shaped bracket 3 can be driven to rotate by the motor, which not only facilitates the adjustment of the U-shaped bracket 3, but also achieves the effect of precise adjustment.

[0076] Furthermore, the U-shaped bracket 3 can be integrated with additional functions such as a power supply, a wireless charging plate, and an audio output structure. By providing a connecting groove inside the U-shaped bracket 3, the connecting line can be connected to the inside of the projector body 1.
