[0036] With the continuous development of projection technology, projectors are increasingly widely used in offices, education, and home entertainment. To achieve the best projection effect, users typically need to adjust the projector's tilt angle according to the environment. Current technologies often employ mechanical adjustment brackets, electric adjustment brackets, pneumatic adjustment brackets, and damped hinge brackets, which have the following characteristics:

[0037] 1. A mechanical adjustment bracket is used. This bracket allows you to manually rotate screws or knobs to adjust the projector's tilt angle. In actual adjustment, users need to loosen the fixing screws first, adjust to the desired angle, and then tighten the screws.

[0038] Advantages: Simple structure and low cost.

[0039] Disadvantages: Cumbersome operation, inaccurate adjustment, and screws are prone to loosening, causing the projector to shake.

[0040] 2. Electrically adjustable stand: This type of stand uses a motor to automatically adjust the projector's tilt angle. Users can set the desired angle via remote control or control panel.

[0041] Advantages: Easy to operate and precise adjustment.

[0042] Disadvantages: Complex structure, high cost, requires additional power supply and control system, and complex maintenance.

[0043] 3. Pneumatic adjustment bracket: This type of bracket uses a pneumatic device to adjust the projector's tilt angle. Users can adjust the angle by controlling the air pressure.

[0044] Advantages: Smooth adjustment, suitable for heavy-duty projectors.

[0045] Disadvantages: Complex structure, high cost, requires gas supply and maintenance.

[0046] 4. Damped hinge bracket: This type of bracket uses a damped hinge to adjust the projector's tilt angle. Users can adjust the angle by manually pressing or lifting the platform.

[0047] Advantages: Easy to operate, precise adjustment, and strong stability.

[0048] Disadvantages: Existing solutions often lack compatibility with various brackets, and the way the projector is fixed to the platform is not convenient enough.

[0049] Therefore, the existing technology has the following drawbacks: First, it is cumbersome to operate. Adjusting the tilt angle of a traditional projector requires loosening screws, manually adjusting the angle, and then tightening the screws again. This operation method involves many steps and is time-consuming, resulting in a poor user experience. Second, the adjustment is inaccurate. Because the manual screw adjustment method lacks a precise control mechanism, users cannot achieve accurate angle adjustments, affecting the projection effect. Third, the applicable scenarios are limited. Existing stands are usually designed with a single function and cannot adapt to various usage scenarios (such as different environments such as desktops and floors), limiting the flexible use of the projector. Fourth, the stability is insufficient. After adjustment, traditional stands may cause the projector to shake due to loose screws or structural instability, affecting the projection effect and user experience. Fifth, the installation is inconvenient. The method of fixing the projector to the platform is complicated, and installation and disassembly are not convenient, increasing the user's operational burden and affecting the user's efficiency.

[0050] Based on this, the present invention provides a projector tilt adjustment platform to solve the above-mentioned shortcomings of the prior art.

[0051] like Figures 1 to 3 As shown, a projector tilt adjustment platform includes a projector 1 and an adjustment platform 2 located below the projector 1. The adjustment platform 2 includes a bottom support plate 21 and a top support plate 22 located above the bottom support plate 21.

[0052] The lower end of the projector 1 is provided with an elastic sleeve 11, and the top support plate 22 is provided with a protruding clip 23 that matches the elastic sleeve 11. Specifically, the elastic sleeve 11 is fixedly installed at the lower end of the projector 1. In actual installation, the protruding clip 23 is fitted into the elastic sleeve 11. This elastic slot structure design of the elastic sleeve 11 can easily fasten the protruding clip 23 into the elastic sleeve 11, thereby facilitating the installation of the projector 1 onto the adjustment platform 2. In addition, this setting makes the installation and removal of the projector 1 from the adjustment platform 2 more convenient and quick, reducing the user's operational burden. At the same time, this setting can also ensure the convenient installation and firm fixation of the projector 1 and the adjustment platform 2.

[0053] Mounting members 25 are provided at the four corners of the top surface of the bottom support plate 21. Damping shafts 251 are provided in the two mounting members 25 located at the rear end of the top surface of the bottom support plate 21. A transition plate 252 is rotatably mounted on the outside of the damping shafts 251. The end of the transition plate 252 away from the damping shafts 251 is connected to the top bearing plate 22. Specifically, damping shafts 251 are provided in the two mounting members 25 located at the rear end of the top surface of the bottom support plate 21, that is, the damping shafts 251 are rotatably mounted in the mounting members 25 located at the rear end of the top surface of the bottom support plate 21.

[0054] Both mounting components 25 located at the front end of the top of the bottom support plate 21 are equipped with connecting rod structures 26.

[0055] Two mounting parts 27 are provided at the front end of the bottom face of the top support plate 22, and the end of the connecting rod structure 26 away from the mounting part 25 is connected to the mounting part 27.

[0056] In this utility model, the design of damping shaft 251 and connecting rod structure 26 simplifies the pitch angle adjustment operation. Users only need to press or lift the adjustment platform 2 to complete the adjustment, thereby solving the problem of cumbersome operation, making the operation simple and significantly improving the user experience.

[0057] Because of the damping pivot 251, the torque is automatically adjusted according to the weight of the projector 1 by the synergistic effect of the damping pivot 251 and the connecting rod structure 26, so as to achieve precise angle control, thereby improving the adjustment accuracy and ensuring the accuracy and stability of the angle adjustment.

[0058] Meanwhile, the design of the linkage structure 26 and the damping shaft 251 ensures the stability of the adjustment platform 2 after adjustment and prevents the projector 1 from shaking.

[0059] like Figures 1 to 7 As shown, in some embodiments of this utility model, a transition mounting hole 24 is also provided in the center of the top surface of the bottom support plate 21.

[0060] The projector is equipped with an adapter mounting hole 24, which allows the projector's tilt adjustment platform to be connected to various brackets, expanding its applicable scenarios and making it suitable for different usage scenarios, such as desktops, floors, etc., thereby improving the projector's flexibility of use.

[0065] like Figures 1 to 7 As shown, in some embodiments of this utility model, the outer circumferential surface of the protruding tack 23 is provided with a plurality of annular misalignment grooves 231.

[0066] like Figures 1 to 7 As shown, in some embodiments of this utility model, the upper end of the outer circumferential surface of the protruding clip 23 is chamfered, so that the upper end of the outer surface of the protruding clip 23 forms a structure that is narrow at the top and wide at the bottom, which can facilitate the accurate assembly of the upper end of the protruding clip 23 with the elastic sleeve 11 at the corresponding position, and thus facilitate the assembly of the protruding clip 23 into the elastic sleeve 11.

[0067] like Figures 1 to 7 As shown, in some embodiments of this utility model, the linkage structure 26 includes a first linkage 261 and a second linkage 262 that are rotatably connected.

[0068] The first link 261 and the second link 262 are located between mounting part 1 25 and mounting part 2 27.

[0069] Specifically, the mounting component 25 and the mounting component 27 can both be composed of two parallel and vertically distributed mounting plates; the two vertical mounting plates form an installation area for the connecting rod structure 26.
