Description

Technical Field

[0001] The utility model relates to the technical field related to projectors, in particular to a support structure for a projector. Background Art

[0002] The projector bracket structures currently on the market have many deficiencies when adjusting the pitch angle, and are unable to meet the user's needs for fast and stable multi-angle adjustment of the projector.

[0003] First, existing projector bracket structures are generally unable to quickly adjust the pitch angle over a wide range. This makes adjusting the projection angle cumbersome and time-consuming, and prevents quick response. Furthermore, even after the pitch angle is adjusted, the limitations of the bracket structure design make the projector less stable when hovering, prone to ineffective rotations such as "bowing the head." This makes it impossible to maintain stable operation at a specific angle, affecting the projection effect.

[0004] Furthermore, existing projector bracket structures typically only adjust the projector's pitch angle, but are unable to adjust the projector's left and right deflection around the vertical axis. This limitation restricts the projector's application scenarios and fails to meet users' diverse projection angle requirements in different environments. For example, when the projected image needs to be moved left or right to accommodate different viewing positions, the existing bracket structure cannot provide effective support, forcing users to manually adjust the projector's position, which increases the inconvenience of use. Utility Model Content

[0005] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a projector bracket structure, aiming to solve the technical problems of the existing projector bracket in terms of angle adjustment range, limited application scenarios, and poor hovering stability.

[0006] The technical solution adopted by the present invention to achieve the above-mentioned purpose is: a projector bracket structure, comprising an assembly bracket for installing the projector, and two side walls of the projector are assembled on the assembly bracket in a relatively rotatable manner.

[0007] It also includes an adjustment mechanism, which includes a mounting shaft, an elastic component, an adjustment cover, an unlocking component, and a damping ring A and a damping ring B that are coaxially arranged relative to each other.

[0012] An assembly ring is fixedly connected to the outer wall of the mounting sleeve, and the adjusting cover is rotatably mounted on the assembly ring. A guide plane is provided on the mounting shaft and arranged on the outer side of the mounting plate. A guide sleeve is fixedly connected to the inner axis of the adjusting cover, and the guide sleeve maintains a sliding connection with the mounting shaft provided with the guide plane.

[0013] The elastic component includes two groups of gaskets and support springs fixed to the two groups of gasket components. The two groups of gaskets are respectively kept in contact with the outer wall of the projector and the inner wall of the mounting plate. The mounting shaft is provided with a guide groove arranged on the inner side of the mounting plate. The guide groove is kept in sliding connection with the gasket and the side wall of the projector.

[0014] In some implementations, in order to ensure that the damping ring A and the damping ring B are in a tightly fitted state to avoid invalid rotation, facilitate the stable assembly of the mounting shaft on the projector and the mounting arm, and prevent the mounting shaft from detaching from the projector, the following technical solutions are provided.

[0015] A positioning plate is provided at the inner end of the installation shaft, and the positioning plate is fixed to the installation shaft by fixing bolts.

[0016] The damping ring A is provided with resistance grooves distributed in a ring array, and the damping ring B is provided with resistance bars distributed in a ring array.

[0021] Beneficial effects of the utility model:

[0022] 1. Pitch Adjustment Across a Wide Range: The adjustment mechanism designed in this application utilizes damping rings A and B to enable rapid pitch adjustment of the projector over a wide range. The resistance grooves and resistance bars on damping rings A and B fit together, providing a stable damping effect during adjustment, ensuring a smooth adjustment process without slippage or sudden imbalance.

[0023] 2. Vertical Axis Tilt Adjustment: This solution not only adjusts the projector's pitch angle, but also includes a support frame and worm gear structure, allowing the projector to be tilted left and right around the vertical axis. By rotating the adjustment knob, the worm gear and worm gear rotate, achieving left and right tilt, expanding the projector's usage scenarios and adapting it to different viewing needs and environmental settings.

[0024] 3. Effective hovering for stable operation*: Through the design of the elastic component and damping ring, damping ring A and damping ring B fit tightly after adjustment, providing effective damping force to prevent the projector from rotating ineffectively. The worm gear and worm structure has a self-locking effect, automatically locking after the deflection angle is adjusted, ensuring that the projector hovers stably at a specific angle, without changing the angle due to external forces or its own weight, ensuring stable operation and image quality.

[0025] 4. Convenient Operation: The unlocking assembly and adjustment mechanism in this solution make it easy to adjust the projector's pitch and yaw angles. Users simply press a button to adjust the projector's angle. Once adjusted, releasing the button securely locks the damping ring to maintain the projector's hovering position. This eliminates the frequent manual adjustments and fixes required with traditional brackets, significantly improving operational efficiency and ease of use.

[0026] To sum up, this solution has made effective improvements based on the existing technology, and can realize the rapid pitch angle adjustment of the projector within a large angle range and the deflection angle adjustment around the vertical axis, while ensuring the stability and hovering effect of the projector after the adjustment is completed. It is simple and convenient to operate, which greatly improves the user experience and adaptability of the projector to application scenarios. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1-9 A projector bracket structure includes an assembly bracket for mounting a projector 1, and two side walls of the projector 1 are assembled on the assembly bracket in a relatively rotatable manner.

[0039] It also includes an adjustment mechanism, which includes a mounting shaft 31, an elastic component 32, an adjustment cover 33, an unlocking component, and a damping ring A35 and a damping ring B36 that are coaxially arranged relative to each other. The mounting shaft 31 is slidably plugged into the side wall of the projector 1, and the mounting shaft 31 is rotatably connected to the assembly bracket. A mounting disk 311 is fixed to the mounting shaft 31. The elastic component 32 is arranged on the periphery of the mounting shaft 31 and is slidably plugged into the mounting shaft 31. The two ends of the elastic component 32 are respectively in contact with the outer wall of the projector 1 and the inner wall of the mounting disk 311. The damping ring A35 is fixed in the assembly bracket, and the damping ring B36 is fixed to the outer wall of the mounting disk 311. The damping ring A35 and the damping ring B36 are both arranged on the periphery of the mounting shaft 31. The adjustment cover 33 is rotatably installed on the assembly bracket and is concentrically arranged with the mounting shaft 31. The mounting shaft 31 is slidably connected to the adjustment cover 33. The unlocking component is assembled on the adjustment cover 33 and is linked to the mounting shaft 31.

[0040] The projector 1 can stably rotate on the mounting bracket around the horizontal axis of the mounting position to achieve rapid adjustment of the projection pitch angle of the projector 1 .

[0041] The adjustment mechanism not only ensures that the projector 1 can rotate about the axis of the mounting shaft 31, but also, after the pitch angle of the projector 1 is adjusted, the elasticity of the elastic component 32 pushes the mounting plate 311 and the mounting shaft 31 to slide outward, thereby driving the nylon ring B fixed to the mounting plate 311 toward the position of the damping ring A35, thereby making the damping ring A35 fit tightly with the damping ring B36. Under the force provided by the elastic component 32, the damping ring A35 and the damping ring B36 fit tightly, effectively limiting the ineffective rotation of the mounting shaft 31 and the projector 1 relative to the assembly bracket, thereby achieving stable hovering of the projector 1 at a specific pitch angle.

[0042] When the unlocking component is in a natural state (without human operation), the elastic component 32 can drive the mounting shaft 31 and the damping ring B36 and the damping ring A35 thereon to be in a fitted and locked state. Since the adjustment cover 33 maintains a sliding connection with the mounting shaft 31, the adjustment cover 33 is in a locked state and the pitch angle of the projector 1 cannot be adjusted to ensure that the projector 1 remains stable at a specific pitch angle.

[0043] When operating the unlocking component, the mounting shaft 31 and the damping ring B36 fixed thereon can be pushed to move the damping ring A35, so that the damping ring A35 and the damping ring B36 are separated to cancel the locking effect on the mounting shaft 31, the adjustment cover 33 and the projector 1. At this time, the adjustment cover 33 is screwed, and the projector 1 is driven to rotate through the mounting shaft 31, thereby realizing effective adjustment of the pitch angle of the projector 1.

[0044] The assembly bracket is arranged on the outside of the projector 1, and there is no spatial motion interference between the two. When adjusting the pitch angle of the projector 1, since the unlocking component is assembled on the adjustment cover 33, the adjustment cover 33 can be rotated while triggering the unlocking component, thereby achieving 360° pitch angle adjustment of the projector 1.

[0045] In order to ensure that the mounted projector 1 can stably rotate on the assembly bracket and ensure that the assembly bracket can stably support the projector 1, the following technical solution is provided.

[0046] The assembly bracket includes a horizontally arranged mounting base 21 and mounting arms 22 fixed to both ends of the mounting base 21 and arranged in the vertical direction. The two side walls of the projector 1 are rotatably mounted on two sets of mounting arms 22 around the same axis. An adjustment mechanism is installed at the connection position between one set of mounting arms 22 and the projector 1, and a pin bolt 41 is installed at the connection position between the other set of mounting arms 22 and the projector 1. The pin bolt 41 is arranged through the mounting arm 22 and is screwed to the side wall of the projector 1.

[0047] The mounting bracket has a U-shaped structure consisting of a mounting base 21 and mounting arms 22, ensuring the projector 1 is stably mounted on the mounting bracket in a relatively rotatable manner. One set of mounting arms 22 is connected to the projector 1 via an adjustment mechanism, facilitating rapid adjustment of the projector 1's pitch angle and enabling hovering and positioning of the projector 1. The other set of mounting arms 22 is connected to the projector 1 via pin bolts 41, which are screwed onto the projector 1. The nuts on the pin bolts 41 limit the mounting arms 22, ensuring stable rotation of the projector 1 around the pin bolts 41 while preventing the projector 1 from separating from the mounting arms 22 on that side.

[0048] A decorative cover 42 is nested and installed on the mounting arm 22 on which the pin rod bolt 41 is assembled. The decorative cover 42 blocks the inner pin rod bolt 41 to improve the overall aesthetics of the structure.

[0049] In order to ensure that the adjustment mechanism can be stably installed on the projector 1 and the mounting arm 22 on the corresponding side, and to facilitate the assembly of the adjustment mechanism, the following technical solution is provided.

[0050] A mounting sleeve 221 is fixedly connected to one set of mounting arms 22, and a limiting plate 222 is fixedly connected to the inner side of the mounting sleeve 221. The mounting shaft 31 is assembled at the axis of the limiting plate 222 in a relative sliding and rotating manner. The damping ring A35 is fixed to the inner side wall of the limiting plate 222. The mounting plate 311 is arranged in the mounting sleeve 221 and is set on the inner side of the limiting plate 222.

[0051] The outer wall of the mounting sleeve 221 is fixedly connected with an assembly ring 223, and the adjustment cover 33 is rotatably mounted on the assembly ring 223. The mounting shaft 31 is provided with a guide plane 312 arranged on the outside of the mounting plate 311. The inner axis of the adjustment cover 33 is fixedly connected with a guide sleeve 331, and the guide sleeve 331 maintains a sliding connection with the mounting shaft 31 provided with the guide plane 312.

[0052] The elastic component 32 includes two sets of gaskets 321 and support springs 322 fixed to the two sets of gaskets 321. The two sets of gaskets 321 are respectively kept in contact with the outer wall of the projector 1 and the inner wall of the mounting plate 311. The mounting shaft 31 is provided with a guide groove 313 arranged on the inner side of the mounting plate 311. The guide groove 313 is kept in sliding connection with the gaskets 321 and the side wall of the projector 1.

[0053] The arrangement of the mounting sleeve 221 and its upper limit plate 222 and the assembly ring 223 can ensure that the mounting shaft 31 and the adjustment cover 33 are stably assembled on the mounting arm 22 on the corresponding side, ensure that the mounting shaft 31 is assembled to the mounting arm 22 in a freely rotating and sliding manner, and ensure that the adjustment cover 33 is assembled to the mounting arm 22 in a relatively rotating manner.

[0054] The setting of the guide plane 312 on the installation shaft 31 and the cooperation with the guide sleeve 331 on the adjustment cover 33 can lead to the installation and relative sliding combination with the adjustment cover 33, while ensuring that the installation shaft 31 and the adjustment cover 33 maintain synchronous rotation.

[0055] The guide slot 313 on the installation shaft 31 is arranged in sliding combination with the side wall of the projector 1 and the backing ring 321, which can ensure that the installation shaft 31, the adjustment cover 33, the projector 1 and the elastic component 32 keep rotating synchronously.

[0056] The elastic component 32 includes two groups of gaskets 321 and a support spring 322 connected between the two groups of gaskets 321. The two groups of gaskets 321 are respectively kept in contact with the outer side wall and the mounting plate 311. The elastic component 32 has a tendency to stretch to push the mounting plate 311 toward the limit plate 222 in the mounting sleeve 221, and realize the close fit between the damping ring A35 and the damping ring B36, so as to realize invalid rotation of the projector 1, the mounting shaft 31, and the adjustment cover 33.

[0057] In order to ensure that the damping ring A35 and the damping ring B36 are in a tightly fitted state to avoid invalid rotation, facilitate the stable assembly of the mounting shaft 31 on the projector 1 and the mounting arm 22, and prevent the mounting shaft 31 from being separated from the projector 1, the following technical solution is provided.

[0058] A positioning plate 314 is provided at the inner end of the mounting shaft 31 , and the positioning plate 314 is fixed to the mounting shaft 31 by fixing bolts 315 .

[0059] The damping ring A35 is provided with resistance grooves 351 distributed in a circular array, and the damping ring B36 is provided with resistance bars 361 distributed in a circular array. When the damping ring A35 and the damping ring B36 are kept in contact, the resistance bars 361 and the resistance grooves 351 are kept nested and matched.

[0060] The mounting plate 311 is detachably assembled to the inner end of the mounting shaft 31 by means of fixing bolts 315. When the adjustment mechanism is assembled, the movement of the mounting shaft 31 can be first assembled to the mounting sleeve 221 of the mounting arm 22. Then, the other end of the mounting shaft 31 passes through the elastic component 32 and the side wall of the projector 1 and extends into the projector 1. Then, the positioning plate 314 is assembled to the inner end of the mounting shaft 31 by means of fixing bolts 315. The positioning plate 314 abuts against the inner wall of the projector 1 to limit the position, which can effectively prevent the mounting shaft 31 from detaching from the projector 1 and also facilitate the stable installation of the mounting shaft 31 between the projector 1 and the mounting arm 22.

[0061] The resistance groove 351 on the damping ring A35 and the resistance bar 361 on the damping ring B36 are arranged opposite to each other. When the damping ring A35 and the damping ring B36 are fitted together by the elastic component 32, the resistance groove 351 and the resistance bar 361 are nested and matched, which can effectively prevent the damping ring A35 and the damping ring B36 from rotating relative to each other, thereby limiting the invalid displacement of the installation shaft 31, the projector 1, and the adjustment cover 33.

[0062] In order to ensure that the unlocking assembly can be stably assembled on the adjustment cover 33, realize the linkage between the unlocking assembly and the installation shaft 31 and trigger the installation shaft 31 to move inward to separate the damping ring A35 and the damping ring B36 to achieve the unlocking effect, the following technical solution is provided.

[0063] A clearance groove 332 is provided on the side wall of the guide sleeve 331, and the unlocking component includes a push button 341, a connecting column 342, and a connecting rod 343. The push button 341 is arranged on the outside of the adjustment cover 33, and the connecting column 342 is slidably installed on the mounting cover and is fixedly connected to the push button 341. The two ends of the connecting rod 343 are respectively hinged to the connecting column 342 and the mounting shaft 31, and the connecting rod 343 is arranged in the clearance groove 332.

[0064] When the unlocking assembly is not operated, the elastic assembly 32 exerts a temporary force on the mounting shaft 31, thereby driving the connecting column 342 and the pressing key 341 to move through the connecting rod 343, so that the pressing key 341 is in a pop-up state.

[0065] When turning the adjustment cover 33 to adjust the pitch angle of the projector 1, first press the push button 341, and then push the mounting shaft 31 inward through the connecting rod 343 to separate the damping ring A35 from the damping ring B36, making it easier to turn the adjustment cover 33 to adjust the pitch angle of the projector 1.

[0066] In order to facilitate effective adjustment of the deflection angle of the projector 1 when rotating left and right, and to effectively increase the angle adjustment range of the projector 1, the following technical solution is provided.

[0067] It also includes a supporting base frame 5, and the mounting base plate 21 is rotatably mounted on the supporting base frame 5. An assembly shell 51 is fixed to the bottom of the supporting base frame 5. A worm gear 52 and a worm 53 are rotatably mounted in the assembly shell 51 to maintain the matching combination. The worm gear 52 is fixedly connected to the mounting base plate 21 through a connecting shaft 521, and the end of the worm 53 is fixedly connected to an adjustment knob 531 arranged on the outside of the assembly shell 51.

[0068] The setting of the assembly shell 51 not only ensures that the worm wheel 52 and the worm 53 are stably installed therein, but also can hide them in the inner cavity to improve the overall aesthetics of the structure. By rotating the adjustment knob 531, the worm 53 can be driven to rotate, thereby driving the worm wheel 52 and the assembly bracket and the projector 1 to rotate stably around the vertical axis, so as to achieve effective adjustment of the deflection angle of the projector 1.

[0069] The worm gear 52 and the worm 53 also have a self-locking effect, that is, power transmission can only be transmitted from the worm 53 to the worm gear 52. After the deflection angle is adjusted, the worm gear 52 is in a locked state, ensuring the posture stability of the projector 1 when maintaining a specific deflection angle.
