Description

Technical Field

[0001] The invention relates to the technical field of projectors, and in particular to a lifting and concealed projector. Background Art

[0002] A projector is a display device that can magnify and project images or video content from a source such as a computer, Blu-ray player, game console, etc. onto a screen or any flat surface. Using an optical system, a projector can create an image large enough for multiple people to view, and is commonly used in conference rooms, classrooms, home theaters, and entertainment venues.

[0003] Existing projectors are generally placed on a desktop for projection, and are removed and stored when not in use, which is inconvenient to use and reduces the practicality of the projector. Existing ceiling projectors are suspended in the air when not in use, affecting the overall appearance. Summary of the invention

[0004] The object of the present invention is to provide a lifting hidden projector, which aims to lift the projector body upward and store it at the top when not in use, thereby saving space, and put it down when in use, thereby making it more convenient to use.

[0005] To achieve the above-mentioned purpose, the present invention provides a lifting hidden projector, including a base and a projector body, two sliders, a screw, two rotating rods and a connecting head, the two sliders are slidably arranged on the base, one end of the two rotating rods is rotatably connected to the connecting head, and the other ends of the two rotating rods are respectively rotatably connected to the two sliders, the screw has two opposite threads, the screw is threadedly connected to the two sliders and rotatably connected to the base, and the projector body is connected to the connecting head.

[0006] Wherein, the connector includes a connector body, a control cylinder, a sliding rod, a universal ball and a connector, the connector body is connected to the two rotating rods, the control cylinder is fixed to the connector body, the sliding rod is fixed to the output end of the control cylinder, and the connector is connected to the sliding rod.

[0007] Wherein, the connector comprises a universal ball, a connection frame and a connection seat, the universal ball is fixed to the sliding rod, the connection frame is sleeved on the universal ball, and the connection seat is arranged at the bottom of the connection frame.

[0008] Wherein, the connector further comprises a locking screw, which is threadably connected to the connection frame and passes through the connection frame.

[0009] Wherein, the lifting hidden projector also includes a protection frame, and the protection frame is fixed to the base.

[0010] Wherein, the lifting hidden projector also includes a decorative light, and the decorative light is arranged on the outside of the protective frame.

[0011] In the present invention, the base of the lifting hidden projector is used as the supporting structure of the whole system, which not only provides a mounting base for other components, but also undertakes the important task of ensuring the stability of the whole device. Two sliders are arranged on the base, and the two sliders can slide linearly on the base. This sliding mechanism is realized by a precision-machined guide rail, which ensures the smoothness and accuracy of the movement of the sliders.

[0012] Connected to the slider are two rotating rods, one end of each rotating rod is connected to the connector, and the other end is connected to the two sliders. This design allows the rotating rod to adjust its angle as the slider slides along the base, thereby driving the connector and the projector body on it to move up and down. In order to achieve this function, the screw has two sections of threads in opposite directions, one section is a forward thread and the other section is a reverse thread, which are threadedly connected to the two sliders respectively. When the screw rotates, due to the effect of the thread, the two sliders will move closer or farther relative to each other according to the direction of rotation of the screw, thereby changing the height position of the projector. Finally, the projector body is fixed to the entire lifting system through the connector. The design of the connector takes into account the weight distribution and center of gravity balance of the projector, ensuring that the projector can remain horizontal whether it is raised or lowered, without affecting the quality of the projected image.

[0013] The design of this liftable hidden projector allows the projector body to be lifted up and stored at the top when not in use, thus saving space, and can be put down when in use, making it more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

In addition, in the description of the present invention, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0023] See also Figure 1 to Figure 5 The present invention provides a lifting hidden projector, including a base 101 and a projector body 102, two sliders 103, a screw 104, two rotating rods 105 and a connecting head 106, the two sliders 103 are slidably arranged on the base 101, one end of the two rotating rods 105 is rotatably connected to the connecting head 106, and the other ends of the two rotating rods 105 are rotatably connected to the two sliders 103 respectively, the screw 104 has two opposite threads, the screw 104 is threadedly connected to the two sliders 103, and is rotatably connected to the base 101, and the projector body 102 is connected to the connecting head 106.

[0024] In this embodiment, the base 101, as the supporting structure of the entire system, not only provides a mounting base for other components, but also undertakes the important task of ensuring the stability of the entire device. Two sliders 103 are arranged on the base 101, and the two sliders 103 can slide linearly on the base 101. This sliding mechanism is realized by a precision-machined guide rail, which ensures the smoothness and accuracy of the movement of the sliders 103.

[0025] Connected to the slider 103 are two rotating rods 105, one end of each rotating rod 105 is connected to the connector 106, and the other end is connected to the two sliders 103. This design allows the rotating rod 105 to adjust its angle when the slider 103 slides along the base 101, thereby driving the connector 106 and the projector body 102 thereon to move up and down. In order to achieve this function, the screw 104 has two sections of threads in opposite directions, one section is a forward thread and the other section is a reverse thread, which are respectively connected to the two sliders 103. When the screw 104 rotates, due to the effect of the thread, the two sliders 103 will be relatively close or far away according to the rotation direction of the screw 104, thereby changing the height position of the projector. Finally, the projector body 102 is fixed to the entire lifting system through the connector 106. The design of the connector 106 takes into account the weight distribution and center of gravity balance of the projector, ensuring that the projector can remain horizontal whether it is raised or lowered, without affecting the quality of the projected image.

[0026] The design of this lifting hidden projector allows the projector body 102 to be lifted up and stored at the top when not in use, thereby saving space, and can be put down when in use, making it more convenient to use.

[0027] The connector 106 includes a connector body 107, a control cylinder 108, a sliding rod 109, a universal ball 110 and a connector 111. The connector body 107 is connected to the two rotating rods 105, the control cylinder 108 is fixed to the connector body 107, the sliding rod 109 is fixed to the output end of the control cylinder 108, and the connector 111 is connected to the sliding rod 109.

[0028] The connector body 107 serves as the base of the entire connection system. It is directly connected to the two rotating rods 105 and not only bears the weight of the projector above, but is also responsible for evenly distributing the force to the slider 103 on the base 101, thereby ensuring the stability and reliability of the entire system.

[0029] A control cylinder 108 is fixed on the connector body 107 to drive the subsequent components to move. The control cylinder 108 can accurately output thrust or pull according to the user's needs through the internal hydraulic or pneumatic mechanism. Its output end is connected to a sliding rod 109, which can freely extend and retract in a straight line, thereby driving the connector 111 connected to its end to move, further realizing the up and down fine adjustment of the projector position.

[0030] The connector 111 includes a universal ball 110 , a connection frame 113 and a connection seat 114 . The universal ball 110 is fixed to the sliding rod 109 . The connection frame 113 is sleeved on the universal ball 110 . The connection seat 114 is arranged at the bottom of the connection frame 113 .

[0031] The universal ball 110 is fixed to the end of the sliding rod 109, allowing the projector to rotate freely in three-dimensional space, so that the user can quickly adjust the projection angle according to actual needs. The connection frame 113 is sleeved on the outside of the universal ball 110, which not only provides the necessary support for the universal ball 110, but also does not hinder its full range of movement. A connection seat 114 is provided at the bottom of the connection frame 113 for directly fixing the projector body 102 to ensure that a firm connection can be maintained under any circumstances.

[0032] The connector 111 further includes a locking screw 115 , which is threadedly connected to the connection frame 113 and passes through the connection frame 113 .

[0033] The connector 111 is also equipped with a locking screw 115, which is to ensure that the position of the projector will not change due to external force after the angle adjustment is completed. The locking screw 115 is threadedly connected to the connection frame 113 and passes through the connection frame 113. When the user tightens the screw, it presses the universal ball 110 to limit its rotation, thereby locking the current projection angle.

[0034] The lifting hidden projector further includes a protection frame 116 , and the protection frame 116 is fixed to the base 101 .

[0035] In order to protect the projector body and its complex lifting mechanism from external environmental influences, such as dust, accidental collisions, etc., the system is equipped with a sturdy protective frame 116. This protective frame 116 is cleverly fixed to the base 101 to form an integral structure with the base 101, which not only increases the stability of the system, but also provides a reliable physical barrier for the internal components.

[0036] The lifting hidden projector further includes a decorative light 117 , and the decorative light 117 is arranged outside the protective frame 116 .

[0037] Secondly, in order to enhance the visual appeal and create a unique atmosphere, the lifting hidden projector is also equipped with decorative lights 117 on the outside of the protective frame 116. These decorative lights 117 are not just simple lighting devices. The location and layout of the decorative lights 117 are planned to add a touch of warmth or cool light and shadow effects to the surrounding environment without interfering with the projected image. The color and brightness of the light can be adjusted according to the user's preferences. For example, in home theater mode, soft warm light can be selected to create a comfortable viewing atmosphere; in business meeting scenes, it can be switched to bright white light to improve the clarity and professionalism of the presentation content.

[0038] What is disclosed above is only a preferred embodiment of the present invention, and it certainly cannot be used to limit the scope of rights of the present invention. Ordinary technicians in this field can understand that all or part of the processes of the above embodiment and equivalent changes made according to the claims of the present invention still fall within the scope of the invention.
