Description

Technical Field

[0001] This utility model relates to the field of display device technology, and more specifically to a magnetic flip projection display device. Background Technology

[0002] The magnetic flip projection display device uses a magnetic force to drive a flip mechanism, enabling automatic adjustment of the display screen's orientation at different angles. This device is widely used in fields such as exhibitions, advertising, and education. By automatically flipping and adjusting the projection angle, it provides a more flexible and multi-angle visual experience. It can project display content to different positions as needed, improving the display effect and enhancing interactivity and audience immersion. Its unique magnetic flip design allows the device to complete the flipping task efficiently and stably, adapting to diverse application scenarios.

[0003] Existing magnetic flip projection display devices have significant limitations in adjustment during use. They cannot achieve full-angle adjustment and can only perform flip operations in a limited number of directions. This leads to problems such as image shifting and distortion after flipping, resulting in a significant decrease in image clarity and projection accuracy. At the same time, the device lacks a flexible position calibration mechanism, making it difficult to adapt to different usage scenarios.

[0004] Therefore, this application provides a magnetic flip projection display device to meet the requirements. Utility Model Content

[0005] In view of this, the present invention provides a magnetic flip projection display device, which aims to solve the above-mentioned technical problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A magnetic flip projection display device includes a housing and a connecting plate disposed inside the housing, and further includes:

[0008] An adjustment assembly includes a projection plate, with connecting seats at each of the four corners of the projection plate. Each connecting seat has a snap-fit ​​groove and a cross shaft. Adjusting blades are rotatably mounted on each cross shaft. Fixed blades are provided on both sides of the projection plate away from the adjusting blades. An electromagnetic component is provided on the side of the connecting plate away from the adjustment assembly.

[0009] Furthermore, a support plate is provided on the side of the connecting plate near the adjustment component, the adjustment components are evenly arranged on the support plate, and a drive plate is provided on the side of the connecting plate away from the support plate.

[0010] The beneficial effects of adopting the above-mentioned further solution are: the connecting plate supports the evenly distributed adjustment components through the support plate, ensuring that the projection plate is subjected to balanced force, and the drive plate is located on the other side of the connecting plate to supply power to the electromagnetic components and transmit control signals.

[0011] Furthermore, the electromagnetic component includes an electromagnetic power supply mounted on the drive board, with a coil mounted on one side of the electromagnetic power supply and guide posts mounted on both sides of the electromagnetic power supply away from the coil.

[0012] The beneficial effects of adopting the above-mentioned further solution are as follows: In the electromagnetic component, the electromagnetic power supply on the drive board supplies power to the coil to generate a magnetic field, and the guide columns on both sides focus the magnetic lines of force to the adjusting blade. When energized, the electromagnetic power supply provides pulse current, the coil generates a controllable magnetic field, the guide columns optimize the magnetic path, and drive the blade to rotate precisely, thereby realizing the dynamic adjustment of the projected display area.

[0013] Furthermore, a main control board is provided on the side of the electromagnetic power supply away from the drive board.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the main control board is installed on the side of the electromagnetic power supply away from the drive board, and controls the current on and off and the strength of the electromagnetic power supply by outputting electrical signals, thereby precisely adjusting the magnetic field strength of the coil and driving the adjustment blade to flip at a set angle.

[0015] Furthermore, the exhaust assembly includes an exhaust port inside the housing, and the housing is provided with fixing frames on both sides away from the exhaust port, and a fan is provided inside each fixing frame.

[0016] The beneficial effects of adopting the above-mentioned further solution are: in the exhaust assembly, the exhaust port inside the outer shell cooperates with the fans in the fixed frames on both sides. When the fans are running, they draw air and exhaust hot air through the exhaust port, reducing the internal temperature of the device and ensuring the stable operation of electromagnetic components, etc.

[0017] Furthermore, a reinforcing nut is provided in the middle of the connecting seat, a fixing shaft is provided on the inner wall of the outer shell, and a snap-fit ​​plate is rotatably provided on the other side of the fixing shaft.

[0018] The beneficial effects of adopting the above-mentioned further solution are: after the reinforcing nut in the middle of the connecting seat is tightened, the fixed component is fixed, the inner wall of the outer shell is fixed, the rotating connecting plate is engaged in the connecting seat slot, and the double reinforcement prevents the adjusting blade from loosening when it flips.

[0019] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a magnetic flip projection display device, which has the following beneficial effects:

[0020] The projection panel is the core of the display. Its four corner connectors are fitted with rotatable adjustment blades through snap-fit ​​slots and cross shafts, while fixed blades on both sides assist in positioning. When the electromagnetic components on the side of the connector are energized, the electromagnetic force acts on the adjustment blades through guide columns, causing them to rotate around the cross shaft. They flip outward to block the edge of the projection panel to reduce the display area, and flip inward to release the edge to expand the area. The fixed blades stabilize the angle of the projection panel. The reinforcement structure of the connector, such as the reinforcing nut, enhances the stability of the components.

[0034] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] like Figures 1-5 As shown, this utility model provides a magnetic flip projection display device, including a housing 1 and a connecting plate 2 disposed inside the housing 1, and further including:

[0036] The adjustment component 3 includes a projection plate 31 with connecting seats 34 at each of its four corners. Each connecting seat 34 has a snap-fit ​​groove 35 and a cross shaft 37. Adjusting blades 33 are rotatably mounted on each cross shaft 37. Fixed blades 32 are located on both sides of the projection plate 31 away from the adjusting blades 33. An electromagnetic component 6 is located on the side of the connecting plate 2 away from the adjustment component 3. The projection plate 31 is the display core. The four corner connecting seats 34 are fitted with rotatable adjusting blades 33 through the snap-fit ​​grooves 35 and cross shafts 37. The fixed blades 32 on both sides assist in positioning. When the electromagnetic component 6 on the side of the connecting plate 2 is energized, electromagnetic force acts on the adjusting blades 33 through guide posts 62, causing them to rotate around the cross shaft 37. The blades rotate outward to block the edge of the projection plate 31 to reduce the display area, and rotate inward to release the edge to expand the area. The fixed blades 32 stabilize the angle of the projection plate 31. The reinforcing structure of the connecting seat 34, such as the reinforcing nut 36, enhances the stability of the component.

[0037] Furthermore, such as Figure 3 As shown: A support plate 4 is provided on the side of the connecting plate 2 near the adjustment component 3. The adjustment components 3 are evenly arranged on the support plate 4. A drive plate 5 is provided on the side of the connecting plate 2 away from the support plate 4. The connecting plate 2 supports the evenly distributed adjustment components 3 through the support plate 4 to ensure that the projection plate 31 is subjected to balanced force. The drive plate 5 is located on the other side of the connecting plate 2 to supply power to the electromagnetic component 6 and transmit control signals.

[0038] Furthermore, such as Figure 4As shown: In this scheme, the electromagnetic component 6 includes an electromagnetic power supply 61 mounted on the drive plate 5. A coil 63 is mounted on one side of the electromagnetic power supply 61, and guide posts 62 are mounted on both sides of the electromagnetic power supply 61 away from the coil 63. In the electromagnetic component 6, the electromagnetic power supply 61 on the drive plate 5 supplies power to the coil 63 to generate a magnetic field. The guide posts 62 on both sides focus the magnetic lines of force to the adjusting blade 33. When energized, the electromagnetic power supply 61 provides a pulse current, the coil 63 generates a controllable magnetic field, and the guide posts 62 optimize the magnetic path, driving the blade to rotate precisely, thereby realizing the dynamic adjustment of the projected display area.

[0039] like Figures 1-5 As shown, the projection plate 31 serves as the display core. The four corner connectors 34, via snap-fit ​​slots 35 and cross shafts 37, mount rotatable adjustment blades 33. Two side-mounted blades 32 assist in positioning and stabilize the angle of the projection plate 31. When the electromagnetic component 6 on the side of the connecting plate 2 is energized, the electromagnetic power supply 61 on the drive plate 5 powers the coil 63. The resulting magnetic field is focused onto the adjustment blades 33 via guide posts 62, causing them to rotate around the cross shaft 37. Rotating outwards blocks the edge of the projection plate 31, reducing the display area; rotating inwards releases the edge, expanding the area. The connecting plate 2, through the support plate 4, evenly supports the adjustment component 3, ensuring the projection plate 31 is subjected to force. In a balanced manner, the drive board 5 on the other side supplies power to the electromagnetic component 6 and transmits signals. The main control board 7 on the side away from the drive board 5 controls the current on and off and the strength through electrical signals, and precisely adjusts the magnetic field strength of the coil 63 to achieve precise blade rotation. In the exhaust component 8, the exhaust port 81 inside the outer shell 1 and the fan 83 inside the fixed frame 82 on both sides work together to exhaust and dissipate heat, control the internal temperature, and ensure the stable operation of the electromagnetic component 6. The reinforcing nut 36 in the middle of the connecting seat 34 and the snap-fit ​​plate 39 rotatably connected to the fixed shaft 38 on the inner wall of the outer shell 1 are snapped into the snap-fit ​​groove 35 to form double reinforcement, preventing the component from loosening when the blade rotates.

Similar or identical parts between embodiments can be referred to interchangeably. For the apparatus disclosed in the embodiments, since they correspond to the methods disclosed in the embodiments, the description is relatively simple; relevant parts can be referred to the method section.
