Technical Field

[0001] This utility model belongs to the field of intelligent electronic equipment and communication technology, specifically an interactive device for intelligent projectors and mobile devices. Background Technology

[0002] In the application of smart projector and mobile device interaction technologies, precise control and real-time interaction are among the key indicators for evaluating the performance of interactive devices. Currently, some interactive devices based on touch or voice control have emerged on the market, but these devices typically rely on a single interaction method, resulting in slow response speeds and difficulty in achieving efficient operation in complex scenarios. Furthermore, the applicability of existing devices in multi-device collaborative work scenarios has certain limitations.

[0003] For example, the Chinese invention patent (publication number: CN108071909B) discloses a "touch interaction device," which includes an operating platform with a mounting structure for fixing an electronic device. The touch plane projected by the electronic device is parallel to the upper surface of the operating platform and has a predetermined height, thereby preventing the electronic device from shaking or being placed unevenly during operation. This application can improve the stability of touch operation in fixed scenarios; however, this device is mainly suitable for static scenarios and lacks support for real-time positioning and tracking of mobile devices, making it difficult to meet the needs of dynamic interaction. The above patent can corroborate the limitations of the prior art.

[0004] Therefore, we have made improvements to this and proposed an intelligent projector and mobile device interaction device. Utility Model Content

[0005] The purpose of this invention is to solve the problems of slow response speed, insufficient precise control capability, and poor adaptability of current smart projectors and mobile device interaction devices in dynamic scenarios.

[0006] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides an interactive device for a smart projector and a mobile device, including an interactive main structure. The interactive main structure includes a positioning and tracking module and a dynamic adjustment module. The top of the positioning and tracking module is provided with a connecting bracket, and the dynamic adjustment module is located inside the positioning and tracking module. The positioning and tracking module and the dynamic adjustment module work together to perform real-time positioning and interactive adjustment of the mobile device. Support components are provided on both sides of the positioning and tracking module, and sliding adjustment components are provided inside the support components.

[0007] The dynamic adjustment module includes a rotating disk, on the circumference of which several positioning sensors are fixedly mounted. A signal transmitter is provided between each of the positioning sensors. The surface of the signal transmitter is covered with a signal enhancement coating. The positioning tracking module includes two positioning wheels located on both sides of the rotating disk. When the positioning wheels roll on the surface of the mobile device, they send positioning signals to the mobile device through the signal transmitter.

[0008] As a preferred technical solution of this application, the connecting bracket includes a fixing plate, and the top of the fixing plate has two assembly slots communicating with the bottom of the fixing plate, and the two positioning wheels are respectively located inside the two assembly slots.

[0009] As a preferred technical solution of this application, the positioning and tracking module further includes two second mounting brackets fixedly connected to the bottom end of the fixed plate, two positioning wheels rotatably connected to opposite sides of the two second mounting brackets, and a rotating disk rotatably connected between the two second mounting brackets. A first mounting bracket fixedly connected to the fixed plate is rotatably provided on the opposite side of the two positioning wheels.

[0010] As a preferred technical solution of this application, the support component includes a guide frame, which is used to connect with the sliding adjustment member.

[0011] As a preferred technical solution of this application, the sliding adjustment component includes a slider that is slidably connected inside the guide frame, and the slider is fixedly connected to the fixing plate.

[0012] As a preferred technical solution of this application, an anti-slip layer is fixedly provided on the circumferential side of the positioning wheel.

[0013] As a preferred technical solution of this application, an elastic element is fixedly provided inside the guide frame, and the end of the elastic element is fixedly connected to the slider.

[0014] As a preferred technical solution of this application, the top of the fixing plate is provided with a through hole communicating with the bottom of the fixing plate, and the through hole is located between two assembly slots.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] By incorporating a dynamic adjustment module and a positioning tracking module, the smart projector achieves real-time tracking and interactive adjustment of the mobile device during interaction. The positioning tracking module acquires the mobile device's location information by contacting or approaching it, and transmits this information to the dynamic adjustment module. The dynamic adjustment module then adjusts the angle and position of the rotating disk based on the received information. This design solves the problems of slow response speed and inconvenient operation caused by existing interactive devices relying on a single interaction method. It also enhances the applicability of multi-device collaborative work and meets the interactive needs in dynamic scenarios.

[0018] Specifically, the positioning wheel in the positioning and tracking module rolls in contact with the surface of the mobile device, driving the signal transmitter to send positioning signals to the mobile device. The signal enhancement coating improves the stability and range of signal transmission, ensuring the accuracy of the positioning information. The rotating disk in the dynamic adjustment module receives positioning signals through a positioning sensor and adjusts its angle accordingly, keeping the projected image from the smart projector synchronized with the mobile device screen. Furthermore, the guide frame and sliding adjustment mechanism in the support assembly provide flexible adjustment capabilities, allowing the entire device to adapt to mobile devices of different sizes and shapes. The inclusion of elastic elements further enhances the device's adaptability, enabling it to maintain stable operation in complex environments.

[0019] In summary, this utility model improves the precision control and real-time interaction efficiency of smart projectors and mobile devices through the synergistic effect of multiple mechanical structures, solving the problems of slow response speed and poor applicability in the prior art, and providing users with a more intelligent, efficient and adaptable interactive solution for changing environments.

[0026] This utility model provides an interactive device for a smart projector and a mobile device, the overall structure of which is as follows: Figure 1 As shown, the interactive main structure 1 comprises a positioning and tracking module 2 and a dynamic adjustment module 3. A connecting bracket 4 is provided on the top of the positioning and tracking module 2, and the dynamic adjustment module 3 is located inside the positioning and tracking module 2 and works in concert through mechanical cooperation. Support components 5 are provided on both sides of the positioning and tracking module 2, and sliding adjustment components 6 are provided inside the support components 5. The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0027] The core component of the dynamic adjustment module 3 is a rotating disk 7. Several positioning sensors 8 are fixedly mounted on the circumference of the rotating disk 7, and a signal transmitter 9 is positioned between adjacent positioning sensors 8. The surface of the signal transmitter 9 is covered with a signal enhancement coating. The positioning tracking module 2 includes two positioning wheels 10 located on either side of the rotating disk 7. The positioning wheels 10 acquire position information by rolling contact with the surface of the mobile device and send positioning signals to the mobile device via the signal transmitter 9. The connecting bracket 4 includes a fixed plate 11. Two mounting slots 12, communicating with the lower part of the fixed plate 11, are formed at the top of the fixed plate 11. The two positioning wheels 10 are respectively embedded in the two mounting slots 12 and can rotate within them. Two secondary mounting brackets 14 are also fixedly connected to the bottom of the fixed plate 11. The two positioning wheels 10 are rotatably connected to opposite sides of the two secondary mounting brackets 14 via rotating shafts. The rotating disk 7 is rotatably connected to the two secondary mounting brackets 14 via a central rotating shaft. Furthermore, the opposite sides of the two positioning wheels 10 are also rotatably engaged with a primary mounting bracket 13 fixedly connected to the fixed plate 11 via rotating shafts.

[0028] The support assembly 5 includes a guide frame 15, which supports the sliding adjustment component 6 and forms a sliding engagement with it. The sliding adjustment component 6 includes a slider 16, which is slidably connected inside the guide frame 15 and fixedly connected to the fixing plate 11. An elastic element 17 is fixedly installed inside the guide frame 15, with one end fixedly connected to the slider 16 and the other end fixedly connected to the inner wall of the guide frame 15. The top of the fixing plate 11 has a through hole 18 communicating with the bottom of the fixing plate 11. The through hole 18 is located between two mounting slots 12, which is used to reduce the overall weight and provide a passage for internal wiring.

[0029] In actual operation, the user places the mobile device within the working range of the positioning and tracking module 2. The positioning wheel 10 has an anti-slip layer on its circumference to increase friction and ensure stable rolling when in contact with the mobile device surface. As the positioning wheel 10 rolls, it drives the signal transmitter 9 to send a positioning signal to the mobile device. The signal enhancement coating improves the stability of signal transmission and expands the signal coverage. After the positioning signal emitted by the signal transmitter 9 is received by the mobile device, it is fed back to the positioning sensor 8. The positioning sensor 8 transmits the received signal to the rotating disk 7 in the dynamic adjustment module 3. The rotating disk 7 adjusts its angle according to the signal content to keep the projected image of the smart projector synchronized with the screen of the mobile device. During this process, the rotation of the rotating disk 7 is achieved through the cooperation between the central shaft and the second mounting bracket 14. The second mounting bracket 14 not only provides support but also ensures smooth and unbiased rotation of the rotating disk 7 through precise manufacturing processes.

[0030] The design of support component 5 further enhances the adaptability of the device. The guide frame 15 is connected to the fixed plate 11 via a sliding adjustment element 6, allowing the slider 16 to adjust its horizontal position as it slides within the guide frame 15. The elastic element 17 enables the slider 16 to automatically rebound when subjected to external force, ensuring good adaptability of the entire device to mobile devices of different sizes and shapes. For example, when the mobile device is large, the guide frame 15 experiences an outward pulling force, causing the slider 16 to slide along the guide frame 15 and compress the elastic element 17; when the external force disappears, the elastic element 17 returns to its original shape, pushing the slider 16 back to its initial position. This design not only improves the flexibility of the device but also enables it to maintain stable operation in complex environments.

[0031] As the core component of the connecting bracket 4, the fixing plate 11 is structurally designed with both strength and functionality in mind. The mounting groove 12 and through hole 18 on the fixing plate 11 are precision-machined to ensure accurate installation of the positioning wheel 10 and internal wiring. Mounting brackets 13 and 14 are fixedly connected to the fixing plate 11 with bolts or other fasteners, and their relative positions are rigorously calibrated to ensure consistent movement trajectories of the rotating disk 7 and the positioning wheel 10. Furthermore, the through hole 18 not only facilitates wiring but also effectively reduces overall weight, making the device lighter and easier to carry.

[0032] In scenarios involving multiple devices working collaboratively, this invention also demonstrates excellent performance. For example, in a conference room, multiple mobile devices need to interact with a smart projector simultaneously. In this case, the positioning and tracking module 2 acquires the location information of each mobile device in real time through the dynamic adjustment module 3, and aggregates this information to the central control system. The central control system adjusts the projection parameters of the smart projector according to the positional relationship of each device, ensuring that the image of each mobile device is synchronized with the projected content. During this process, the cooperation of the signal enhancement coating and the elastic element 17 ensures accurate positioning and efficient interaction even in multi-device environments.

[0033] This invention achieves efficient interaction between the smart projector and mobile devices through the aforementioned structural design, solving the problems of slow response speed, inconvenient operation, and poor adaptability to multi-device collaborative work in existing technologies. The close cooperation between the various components ensures the stability and reliability of the device in dynamic scenarios, providing users with a highly intelligent and widely applicable solution.

[0034] To enable those skilled in the art to fully understand and implement this utility model, the following supplementary explanation of the specific implementation principle of this utility model is provided in conjunction with a specific application scenario.

[0035] First, the user places the mobile device within the working range of the positioning and tracking module 2. At this time, the anti-slip layer on the circumferential side of the positioning wheel 10 contacts the surface of the mobile device and rolls on the surface to acquire position information. As the positioning wheel 10 rolls, it mechanically drives the signal transmitter 9 to send a positioning signal to the mobile device. The signal enhancement coating improves the stability of the signal emitted by the signal transmitter 9 and expands the signal coverage, thereby ensuring that the mobile device can accurately receive the positioning signal. After receiving the positioning signal, the mobile device transmits a feedback signal to the positioning sensor 8. The positioning sensor 8 further transmits the received feedback signal to the rotating disk 7 in the dynamic adjustment module 3. The rotating disk 7 adjusts its angle according to the received signal content; this process is achieved through the cooperation between the central rotating shaft and the second mounting bracket 14. The second mounting bracket 14 not only provides support but also ensures smooth and unbiased rotation of the rotating disk 7 through precise manufacturing processes, thus keeping the projected image of the smart projector synchronized with the screen of the mobile device.

[0036] Secondly, in scenarios involving multi-device collaboration, multiple mobile devices are simultaneously placed within the working range of the positioning and tracking module 2. Positioning wheels 10 roll in contact with the surfaces of each mobile device, sending independent positioning signals to each device via signal transmitter 9. A signal enhancement coating ensures stable signal transmission and wide coverage even in multi-device environments. After receiving their respective positioning signals, the mobile devices transmit feedback signals to positioning sensors 8. Positioning sensors 8 aggregate the position information of each device to the central control system. The central control system adjusts the projection parameters of the smart projector, such as screen size and projection angle, based on the positional relationship of each device, ensuring that the image on each mobile device is synchronized with the projected content. The design of the elastic element 17 plays a crucial role in this process. When the size or shape of the mobile devices differs, the guide frame 15 experiences outward tension, causing the slider 16 to slide along the guide frame 15 and compress the elastic element 17. When the external force disappears, the elastic element 17 returns to its original shape, pushing the slider 16 back to its initial position. This design ensures that the device can adapt to mobile devices of different sizes and shapes, thus maintaining stable operation in complex environments.

[0037] Furthermore, the fixing plate 11, as the core component of the connecting bracket 4, is structurally designed with both strength and functionality in mind. The mounting groove 12 on the fixing plate 11 is precision-machined to ensure the accurate installation position of the positioning wheel 10. Mounting brackets 13 and 14 are fixedly connected to the fixing plate 11 with bolts or other fasteners, and their relative positions are rigorously calibrated to ensure consistent movement trajectories of the rotating disk 7 and the positioning wheel 10. In addition, the through-hole 18 not only facilitates wiring but also effectively reduces the overall weight, making the device lighter and easier to carry. This design significantly improves the ease of operation and applicability of the device in practical applications.

[0038] Finally, in dynamic scenarios, such as when multiple mobile devices in a conference room need to move or adjust their positions frequently, the positioning and tracking module 2 obtains the latest position information of each mobile device in real time through the dynamic adjustment module 3 and transmits this information to the central control system. The central control system adjusts the projection parameters of the smart projector according to the latest positional relationship, ensuring that the image of each mobile device remains synchronized with the projected content. The combination of the signal enhancement coating and the elastic element 17 ensures that the device can still achieve accurate positioning and efficient interaction even in dynamic scenarios. The guide frame 15 is connected to the fixed plate 11 through the sliding adjustment piece 6, and the slider 16 can adjust its position in the horizontal direction when sliding inside the guide frame 15. This flexible adjustment capability allows the device to quickly adapt to changes in the position of mobile devices, thereby maintaining efficient and stable interactive performance in dynamic scenarios.

[0039] In summary, this invention achieves efficient interaction between a smart projector and a mobile device through the aforementioned steps and principles. The close cooperation between the various components ensures the stability and reliability of the device in both static and dynamic scenarios, providing users with a highly intelligent and widely applicable solution.
