Description

Technical Field

[0001] The present invention relates to the field of projection technology, and more particularly, to a curtain rotating mechanism. Background Art

[0002] In the related art, the cooperation between a curtain and a projection device has become an important tool for displaying information and playing videos. However, traditional curtains and projection devices are often fixedly installed in a certain position, which greatly limits their flexibility. Since the angle and position of the curtain cannot be adjusted according to the change of the user's position, the user usually has to stay in a certain position to view the clear projection content. This fixed installation method reduces the comfort and convenience of the user's viewing. Summary of the Invention

[0003] The purpose of the present invention is to provide a curtain rotating mechanism, which realizes the overall rotation of the curtain device and the projection device, so that users can view clear projection content at different viewing positions, not only improving the viewing comfort, but also increasing the convenience of use.

[0004] A curtain rotating mechanism includes a rotating part and a fixed part; The rotating part includes a carrier, and a curtain device and a projection device oppositely arranged on the carrier; The fixed part includes a fixing plate and a rotating device arranged on the fixing plate. The rotating device includes a driving member and a rotating bearing. The carrier is connected to the rotating bearing, the output end of the driving member is connected to the carrier, and the driving member can drive the rotating part to rotate relative to the fixed part with the rotating bearing as the axis.

[0005] In the above technical solution, when it is necessary to adjust the angle or position of the curtain, the user can start the driving member to provide the power required for rotation. The output end of the driving member is connected to the carrier. Through the driving of the driving member, the carrier can rotate relative to the fixed part with the rotating bearing as the axis. As the carrier rotates, the curtain device and the projection device will also rotate as a whole. In this way, the user can adjust the angle and position of the curtain according to the need to obtain the best viewing effect. At the same time, since the curtain device and the projection device are oppositely arranged and fixed on the same carrier, it can ensure that the image can be accurately projected onto the curtain without deviation or distortion due to rotation.

[0006] Further, the carrier is provided with a first roller, the fixing plate includes a first surface and a second surface facing in opposite directions, and the first roller abuts against the first surface.

[0007] In the above technical solution, the first roller abuts against the first surface of the fixed plate, replacing direct sliding contact, thus significantly reducing the frictional force during rotation. This not only makes the rotation of the rotating part smoother but also extends the service life of the mechanism. At the same time, the design of the first roller also helps to maintain the balance of the carrier during rotation, reducing stability problems caused by shaking or uneven loading.

[0008] Further, the fixed plate is provided with guide grooves on both sides of the rolling path of the first roller. Guide rods are respectively connected to opposite sides of the first roller, and the guide rods extend into the guide grooves one by one.

[0009] In the above technical solution, the cooperation of the guide grooves and the guide rods ensures the precise guidance and stable movement of the carrier during rotation. This design effectively prevents the carrier from shifting or shaking during rotation, thus ensuring the precise positioning and stable display of the curtain device and the projection device.

[0010] Further, one end of the guide rod extending into the guide groove is formed as a mobile end. A second roller is provided between the two mobile ends. The second roller abuts against the second surface, and the fixed plate is clamped between the first roller and the second roller.

[0011] In the above technical solution, the rolling contact between the second roller and the second surface of the fixed plate provides additional rolling support for the carrier. This helps to disperse the force on the carrier during rotation, reducing the dependence on a single roller or guide groove, thereby improving the stability and durability of the entire mechanism.

[0012] Further, a plurality of feet are provided on the second surface.

[0013] In the above technical solution, the feet, as support components, can increase the contact area between the fixed plate and the ground or the mounting surface, thereby improving the stability of the entire mechanism. This helps to prevent shaking or tilting caused by external forces, ensuring the smoothness and safety of the entire rotating part during rotation.

[0014] Further, the projection device includes a telescopic component and a projection component. The telescopic component can drive the projection component to move, so that the projection component moves away from or closer to the curtain device.

[0015] In the above technical solution, the telescopic component can drive the projection component to move away from or closer to the curtain device, thereby allowing the user to adjust the projection distance according to actual needs. This design enables the size and clarity of the projection image to be precisely adjusted according to the viewing requirements, providing a more personalized viewing experience for the user.

[0016] Further, the telescopic assembly includes a fixing member and at least one telescopic member. The fixing member is fixedly arranged on the bearing member, and adjacent telescopic members are slidably connected to each other. The telescopic member close to the fixing member is slidably connected to the fixing member.

[0017] In the above technical solution, the fixing member is fixedly arranged on the bearing member, providing a stable support foundation for the telescopic assembly, ensuring that the telescopic assembly will not shake or tilt when adjusting the projection distance, thereby guaranteeing the stability and clarity of the projection screen. Through the sliding connection between adjacent telescopic members and the sliding connection between the telescopic member close to the fixing member and the fixing member, the telescopic assembly can flexibly adjust the distance between the projection assembly and the curtain device, enabling the user to easily change the size and position of the projection screen according to actual needs.

[0018] Further, sliding rails are provided on the outer side walls of the fixing member and the telescopic members, and adjacent two sliding rails form a sliding fit.

[0019] In the above technical solution, the design of the sliding rails provides a more stable sliding track for the telescopic assembly, reducing errors caused by shaking or tilting, ensuring that the telescopic assembly can remain stable and accurate when adjusting the projection distance, thereby guaranteeing the stability and clarity of the projection screen.

[0020] Further, limiting structures are respectively provided between adjacent telescopic members and between the fixing member and the telescopic members.

[0021] In the above technical solution, the limiting structure can limit the relative sliding distance between the telescopic members, preventing structural damage or functional failure caused by excessive sliding, and helping to protect the integrity of the telescopic assembly and extend its service life.

[0022] Further, a camera is provided on the telescopic member far from the fixing member.

[0023] In the above technical solution, the camera can capture and identify the user's face features in real time, thereby realizing fast and accurate identity verification. When the preset face information is captured by the camera, the rotating device drives the bearing member to rotate, and then realizes the rotation of the curtain device and the projection device.

[0024] Compared with the prior art, the beneficial effects of the present invention are as follows: When it is necessary to adjust the angle or position of the curtain, the user can start the driving member to provide the power required for rotation. The output end of the driving member is connected to the bearing member. Through the driving of the driving member, the bearing member can rotate relative to the fixed part with the rotating bearing as the axis. As the bearing member rotates, the curtain device and the projection device will also rotate as a whole. In this way, the user can adjust the angle and position of the curtain according to needs to obtain the best viewing effect. At the same time, since the projection device and the curtain device are oppositely arranged and fixed on the same bearing member, it can ensure that the image can be accurately projected onto the curtain without deviation or distortion due to rotation.

[0032] The following will further describe the curtain rotating mechanism of the present invention in detail in conjunction with specific embodiments and the accompanying drawings. The preferred embodiments of the present invention are shown in the drawings. However, the present invention can be implemented in many different forms and is not limited to the embodiments described herein.

[0033] Please refer to Figures 1 to 3 , in a preferred embodiment, the curtain rotating mechanism of the present invention includes a rotating part 1 and a fixed part 2; The rotating part 1 includes a carrier 101, and a curtain device 102 and a projection device 103 oppositely arranged on the carrier 101; The fixed part 2 includes a fixing plate 201 and a rotating device 202 provided on the fixing plate 201. The rotating device 202 includes a driving member 2021 and a rotating bearing 2022. The carrier 101 is connected to the rotating bearing 2022, and the output end of the driving member 2021 is connected to the carrier 101. The driving member 2021 can drive the rotating part 1 to rotate relative to the fixed part 2 with the rotating bearing 2022 as the axis.

[0034] By adopting the above solution, when the angle or position of the curtain needs to be adjusted, the user can start the driving member 2021 to provide the power required for rotation. The output end of the driving member 2021 is connected to the carrier 101. Driven by the driving member 2021, the carrier 101 can rotate relative to the fixed part 2 with the rotating bearing 2022 as the axis. As the carrier 101 rotates, the curtain device 102 and the projection device 103 will also rotate as a whole. In this way, the user can adjust the angle and position of the curtain according to needs to obtain the best viewing effect. At the same time, since the curtain device 102 and the projection device 103 are oppositely arranged and fixed on the same carrier 101, it can ensure that the image can be accurately projected onto the curtain without deviation or distortion due to rotation.

[0035] Further, please refer to again Figure 3, the carrier 101 is provided with a first roller 104. The fixing plate 201 includes a first surface 2011 and a second surface 2012 facing in opposite directions, and the first roller 104 abuts against the first surface 2011. The abutment of the first roller 104 against the first surface 2011 of the fixing plate 201 replaces the direct sliding contact, thus significantly reducing the frictional force during rotation. This not only makes the rotation of the rotating part 1 smoother but also extends the service life of the mechanism. At the same time, the design of the first roller 104 also helps to maintain the balance of the carrier 101 during rotation, reducing the stability problems caused by shaking or uneven loading. That is to say, the first roller 104 on the carrier 101 forms a rolling contact with the first surface 2011 of the fixing plate 201. When the driving member 2021 is activated, the power it generates is transmitted to the carrier 101 through the rotating bearing 2022, thereby driving the first roller 104 to roll on the first surface 2011. This rolling contact method effectively reduces the frictional resistance during rotation, enabling the curtain device 102 and the projection device 103 to easily achieve rotation and positioning.

[0036] In some embodiments of the present invention, the fixing plate 201 is provided with guide grooves 203 on both sides of the rolling path of the first roller 104. Guide rods 105 are respectively connected to the opposite sides of the first roller 104, and the guide rods 105 extend into the guide grooves 203 one by one. The cooperation between the guide grooves 203 and the guide rods 105 ensures the precise guiding and stable movement of the carrier 101 during rotation. This design effectively prevents the carrier 101 from shifting or shaking during rotation, thus ensuring the precise positioning and stable display of the curtain device 102 and the projection device 103. Specifically, please refer to Figure 3 , the guide grooves 203 are arranged in an arc shape and penetrate through the fixing plate 201. The curvature of the guide grooves 203 is the same as the curvature of the rolling path of the first roller 104. When the first roller 104 rolls on the first surface 2011 of the fixing plate 201, the guide rods 105 move in the guide grooves 203 at the same time. That is to say, the guide grooves 203 can limit the rotation angle and path of the rotating part 1, preventing the rotating part 1 from over-rotating and being damaged.

[0037] Please refer to Figure 4, one end of the guide rod 105 extending into the guide groove 203 is formed as a mobile end 1051. A second roller 106 is provided between the two mobile ends 1051. The second roller 106 abuts against the second surface 2012. The fixing plate 201 is clamped between the first roller 104 and the second roller 106. The rolling contact between the second roller 106 and the second surface 2012 of the fixing plate 201 provides additional rolling support for the carrier 101. This helps to disperse the force on the carrier 101 during rotation, reduces the dependence on a single roller or the guide groove 203, and thus improves the stability and durability of the entire mechanism. By introducing the second roller 106, the force distribution on the carrier 101 during rotation is more uniform, which helps to reduce structural deformation or damage caused by uneven force, thereby extending the service life of the mechanism. The second roller 106 and the first roller 104 act together to provide a more stable and accurate rolling path for the carrier 101, which helps to ensure that the curtain device 102 and the projection device 103 are in the correct position after rotation and improves the smoothness during rotation.

[0038] Please refer to Figure 1 , a plurality of feet 204 are provided on the second surface 2012. As a support component, the feet 204 can increase the contact area between the fixing plate 201 and the ground or the mounting surface, thereby improving the stability of the entire mechanism. This helps to prevent shaking or tilting caused by external forces and ensures the smoothness and safety of the entire rotating part 1 during rotation. When installing the curtain rotating mechanism, the user can adjust the height and levelness of the feet 204 according to actual needs to make the fixing plate 201 reach the ideal installation position. The close contact between the feet 204 and the ground or the mounting surface provides a stable supporting effect and helps to prevent the mechanism from shaking or tilting.

[0039] Further, please refer to Figure 1 and Figure 2 , the projection device 103 includes a telescopic component 1031 and a projection component 1032. The telescopic component 1031 can drive the projection component 1032 to move so that the projection component 1032 moves away from or closer to the curtain device 102. The telescopic component 1031 can drive the projection component 1032 to move away from or closer to the curtain device 102, thereby allowing the user to adjust the projection distance according to actual needs. This design enables the size and clarity of the projection image to be precisely adjusted according to viewing requirements, providing a more personalized viewing experience for the user. When the projection distance needs to be adjusted, the user can manually push the telescopic component 1031. The telescopic component 1031 drives the projection component 1032 to move through components such as guide rails or slide rails, thereby changing the distance between the projection component 1032 and the curtain device 102.

[0040] Specifically, please refer to Figure 5, the telescopic component 1031 includes a fixing member 1031a and at least one telescopic member 1031b. The fixing member 1031a is fixedly arranged on the bearing member 101, and the adjacent two telescopic members 1031b are slidably connected, and the telescopic member 1031b close to the fixing member 1031a is slidably connected with the fixing member 1031a. The fixing member 1031a is fixedly arranged on the bearing member 101, providing a stable support foundation for the telescopic component 1031, ensuring that the telescopic component 1031 will not shake or tilt when adjusting the projection distance, thus ensuring the stability and clarity of the projection screen. Through the sliding connection between the adjacent two telescopic members 1031b and the sliding connection between the telescopic member 1031b close to the fixing member 1031a and the fixing member 1031a, the telescopic component 1031 can flexibly adjust the distance between the projection component 1032 and the curtain device 102, enabling the user to easily change the size and position of the projection screen according to actual needs. Specifically, when the position of the projection component 1032 needs to be adjusted, the user can manually or through an auxiliary device push the telescopic member 1031a to slide, realizing the position adjustment of the projection component 1032 relative to the curtain device 102. Through the sliding adjustment of the telescopic member 1031a, the user can flexibly position the projection component 1032 at the desired position.

[0041] In some embodiments of the present invention, slide rails 1031c are provided on the outer side walls of the fixing member 1031a and the telescopic member 1031b, and the adjacent two slide rails 1031c form a sliding fit. The design of the slide rail 1031c provides a more stable sliding track for the telescopic component 1031, reducing the errors caused by shaking or tilting, ensuring that the telescopic component 1031 can remain stable and accurate when adjusting the projection distance, thus ensuring the stability and clarity of the projection screen.

[0042] Furthermore, please refer to Figure 6 , limiting structures 1031d are respectively provided between the adjacent two telescopic members 1031b and between the fixing member 1031a and the telescopic member 1031b. The limiting structure 1031d can limit the relative sliding distance between the telescopic members 1031b, prevent structural damage or functional failure caused by excessive sliding, and contribute to protecting the integrity of the telescopic component 1031 and extending its service life. Specifically, please refer to Figure 6, the limiting structure 1031d is composed of two mutually abutting baffles. When one telescopic member 1031b moves to the end of the adjacent telescopic member 1031b, the baffles provided at the ends of the two telescopic members 1031b abut against each other. Similarly, when the telescopic member 1031b close to the fixing member 1031a moves to the end of the fixing member 1031a, the baffle provided at the end of the telescopic member 1031b abuts against the baffle provided at the end of the fixing member 1031a. The above limiting structure 1031d prevents excessive movement of two adjacent telescopic members 1031b, thereby ensuring the stability of the projection assembly 1032 during movement.

[0043] Furthermore, a camera 107 is provided on the telescopic member 1031b away from the fixing member 1031a. The camera 107 can capture and identify the user's face features in real time, so as to achieve fast and accurate identity verification. When the camera 107 captures the preset face information, the rotating device 202 drives the carrier 101 to rotate, thereby realizing the rotation of the curtain device 102 and the projection device 103. Specifically, when the camera 107 captures a face, it sends the captured face information to the backend control system (not shown in the drawings). After receiving the face information sent by the camera 107, the backend control system compares the face information with the preset user face information in the backend control system through a face recognition algorithm. After successful comparison, the backend control system sends a signal to the rotating device 202. After receiving the signal, the rotating device 202 drives the carrier 101 to rotate around the rotary bearing 2022 relative to the fixing part 2. Since the curtain device 102 and the projection device 103 are both installed on the carrier 101, when the carrier 101 rotates, the curtain device 102 and the projection device 103 will rotate together until the curtain device 102 rotates to a position facing the user directly, ensuring that the user can view the picture from the best angle.
