Description

Technical Field

[0001] This invention relates to the field of projection equipment accessories technology, and more specifically, to a screen stabilization module for improving the display effect of DMD chips. Background Technology

[0002] A projector is a device that projects light onto an image display element to produce an image, which is then projected onto a screen through a lens. Projectors can also be connected to computers, VCD players, DVD players, BD players, game consoles, DV players, etc., through different interfaces to play corresponding video signals.

[0003] Currently, projector modules on the market consist of a mounting bracket and spring clips connecting to the bracket. Because projectors typically integrate speakers, installing a module within the projector can cause resonance at certain frequencies due to the sound waves from the speakers. This resonance causes the module to vibrate axially (vertically in the attached diagram), resulting in vibration of the chip within the module and ultimately causing screen flickering during projection. Summary of the Invention

[0004] To address the shortcomings of existing technologies, the present invention aims to provide a screen stabilization module that offers strong stability, excellent image stabilization performance, simple structure, and improved display performance of DMD chips.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a screen stabilization module for improving the display effect of a DMD chip, comprising a fixed frame and a spring connected to the fixed frame, wherein a stabilization structure for improving the display stabilization effect of the DMD chip is provided between the fixed frame and the spring, and the stabilization mechanism consists of a horizontal connection structure and a vertical connection structure.

[0006] By adopting the above technical solution, an anti-shake structure is provided between the fixing frame and the spring to improve the anti-shake effect of the DMD chip display. In order to improve the anti-shake effect, the anti-shake structure is set up, and the anti-shake mechanism is set to consist of a horizontal connection structure and a vertical connection structure. The horizontal connection structure and the vertical connection structure are used for bidirectional fixation, and the setting of the vertical connection structure can form a vertical fixation effect to balance the vertical force generated by the vibration from the speaker.

[0007] The present invention is further configured such that: the horizontal connecting structure includes a horizontal connecting piece connected to the spring and a first connecting member for connecting the horizontal connecting piece and the fixing frame; the vertical connecting structure includes a vertical connecting piece connected to the spring and a second connecting member for fixing.

[0008] By adopting the above technical solution, the horizontal connection structure includes a horizontal connecting piece connected to the spring and a first connecting member for connecting the horizontal connecting piece and the fixing frame. The vertical connection structure includes a vertical connecting piece connected to the spring and a second connecting member for fixing. By using the horizontal connecting piece in conjunction with the first connecting member and the vertical connecting piece in conjunction with the second connecting member to fix the spring in both directions, the structural stability is improved, the practicality is strong, and the structure is simple.

[0009] The present invention is further configured such that: a first positioning structure is provided between the horizontal connecting piece and the fixing frame, the first positioning structure including a first mounting groove disposed on the fixing frame and adapted to the horizontal connecting piece for placing the horizontal connecting piece, a first positioning hole disposed on the horizontal connecting piece, and a first positioning post disposed on the first mounting groove and penetrating the first positioning hole.

[0010] By adopting the above technical solution, a first positioning structure is also provided between the horizontal connecting piece and the fixed frame. In order to improve the stability between the horizontal connecting piece and the fixed frame, the first positioning structure improves the good stability effect between the two. The first positioning structure is further configured to include a first mounting groove provided on the fixed frame and adapted to the horizontal connecting piece for placing the horizontal connecting piece, a first positioning hole provided on the horizontal connecting piece, and a first positioning post provided on the first mounting groove and passing through the first positioning hole. Through the cooperation between the first positioning hole and the first positioning post, the horizontal connecting piece is prevented from twisting under force after being subjected to the locking pressure of the first connecting piece.

[0011] The present invention is further configured such that: a second positioning structure is provided between the vertical connecting piece and the fixing frame, the second positioning structure including a second mounting groove disposed on the fixing frame and adapted to the vertical connecting piece, a second positioning hole disposed on the vertical connecting piece, and a second positioning post disposed on the second mounting groove and penetrating the second positioning hole.

[0012] By adopting the above technical solution, a second positioning structure is also provided between the vertical connecting piece and the fixing frame. In order to improve the connection stability between the vertical connecting piece and the fixing frame, the second positioning structure improves the positioning effect between the vertical connecting piece and the fixing frame, and avoids the vertical connecting piece from shifting its position when subjected to force. The second positioning structure is configured to include a second mounting groove on the fixing frame that is adapted to the vertical connecting piece, a second positioning hole on the vertical connecting piece, and a second positioning post on the second mounting groove that passes through the second positioning hole. Through the cooperation between the second positioning hole and the second positioning post, a positioning effect is formed for the vertical connecting piece when it is connected and fixed, which improves stability, is highly practical, and has a simple structure.

[0013] The present invention is further configured such that: the horizontal connecting piece includes a connecting part A with the fixed frame, the vertical connecting piece includes a connecting part B with the fixed frame, and the ratio between the height between the connecting part A and the bottom surface of the fixed frame and the height between the connecting part B and the bottom surface of the fixed frame is between 1.6 and 2.

[0014] By adopting the above technical solution, the horizontal connecting piece includes a connecting part A with the fixed frame, and the vertical connecting piece includes a connecting part B with the fixed frame. The ratio between the height of connecting part A and the bottom surface of the fixed frame and the height of connecting part B and the bottom surface of the fixed frame is between 1.6 and 2. By setting the above structure, the ratio between the height of connecting part A and the bottom surface of the fixed frame and the height of connecting part B and the bottom surface of the fixed frame is set between 1.6 and 2. In order to improve the anti-vibration effect of connecting part B after fixing, the connection position of connecting part B is controlled. When connecting part B is subjected to the force generated by resonance, the lever arm is controlled to improve the strength of connecting part B. Furthermore, by setting the above ratio for connecting parts A and B, the force between connecting parts A and B is more uniform, thereby improving the structural stability and making it highly practical.

[0015] The present invention is further configured such that: the vertical connecting piece further includes an extension portion connected to the template and extending vertically downward, and a steering connector integrally connected to the extension portion and the connecting part B in sequence.

[0016] By adopting the above technical solution, the vertical connecting piece also includes a vertically downward extension connected to the template and a steering connector that is integrally connected to the extension and the connecting part B in sequence. By adopting the above structural setting, the vertical connecting piece is improved in terms of structural stability by transferring the force in two directions. It is practical, simple in structure, and enables the horizontal and vertical connecting structures to achieve stress stability. This avoids the spring piece from shifting when fixed on one side, thus affecting the practical effect.

[0017] The present invention is further configured such that the distance between the connecting part A and the spring piece is the same as the distance between the connecting part B and the spring piece.

[0018] By adopting the above technical solution, the distance between the connecting part A and the spring piece is the same as the distance between the connecting part B and the spring piece. By setting the distance between the connecting part A and the spring piece and the distance between the connecting part B and the spring piece to be the same, the force points of the connecting parts A and B are more uniform, thereby improving the stability when subjected to vibration. It is highly practical and has a simple structure.

[0029] The present invention is further configured such that a first positioning structure is provided between the horizontal connecting piece 201 and the fixing frame 1. In order to improve the stability between the horizontal connecting piece and the fixing frame, the first positioning structure improves the stability between the two.

Through the cooperation between the first positioning hole 203 and the first positioning post 101, the horizontal connecting piece 201 is prevented from twisting under the force after being subjected to the locking pressure of the first connecting member 202.

[0030] The present invention is further provided with a second positioning structure between the vertical connecting piece 210 and the fixing frame 1.

Furthermore, the connecting parts A and B set with the above ratio make the force between the connecting parts A204 and B213 more uniform, thereby improving the structural stability and making it highly practical.

[0032] The present invention is further configured such that the vertical connecting piece 210 also includes a vertically downward extending portion 3 connected to the spring piece 2 and a steering connector 4 integrally connected to the extending portion 3 and the connecting portion B213 in sequence. By adopting the above structural configuration, the vertical connecting piece 210 is improved in terms of structural stability by transferring the force in two directions. It is practical, simple in structure, and enables the horizontal connecting structure 20 and the vertical connecting structure 21 to achieve force stability.
