Description

Technical Field

[0001] The present invention relates to the technical field of interactive tablet computers, and in particular to a gesture-controlled smart tablet computer. Background Art

[0002] A tablet is a small, portable personal computer that is usually equipped with a touch screen interface that allows users to input and interact through finger touch or gesture operation. Gesture control is a very practical feature on tablets. Through different gestures, users can perform various operations more conveniently and efficiently. At present, smart tablets with air gesture control usually use cameras to collect user gestures in real time.

[0003] The Chinese patent discloses a camera assembly and an interactive tablet (authorization announcement number CN114631303B). The lifting bracket, module support, camera module and drive module are arranged in the frame of the interactive tablet, and the cover body can cover the second through hole to prevent foreign debris, dust, etc. from entering the frame of the interactive tablet through the second through hole, thereby preventing the camera module and other functional components in the frame of the interactive tablet from affecting the camera module and the frame of the interactive tablet. At the same time, the frame of the interactive tablet has good integrity and high appearance.

[0004] According to the above reference cases, the above device combines the linear sliding motion and axial flipping motion of the camera to meet the shooting requirements at different angles. Although the above device adopts a cover body for dust protection, the cover body can only block the dust on its surface. When the camera module rotates, there is an obvious gap between the top opening and the camera module, and the dust can easily fall off due to the displacement of the cover body, which increases the probability of dust entering the tablet computer and greatly interferes with the linear sliding motion and axial flipping motion of the camera module. Summary of the invention

[0005] Based on this, it is necessary to provide a gesture-controlled smart tablet computer to address the problem that the existing gesture-controlled smart tablet computers have poor protection performance and affect user use.

[0006] A gesture-controlled smart tablet computer comprises a tablet computer and a gesture control system. A mounting cavity is provided on the top of the tablet computer, and an adjustable camera mechanism is installed inside the mounting cavity.

[0007] Furthermore, the adjustable camera mechanism includes a micro servo motor fixedly connected to the bottom wall of the mounting cavity, the top of the micro servo motor is fixedly connected with a threaded column, the surface of the threaded column is threadedly connected with a threaded push plate slidably connected to the mounting cavity, the top of the threaded push plate is fixedly connected with an angle adjustment component fixedly connected to the mounting cavity, a mounting shell is installed on the inner side of the angle adjustment component, one end of the mounting shell is embedded with a camera module, the surface of the mounting shell is provided with an elastic sealing sleeve fixedly connected to the mounting cavity, the top of the mounting shell is fixedly connected with a dust cover, the top of the mounting shell is provided with an air guide cavity, the lower opening of the air guide cavity is always arranged below the elastic sealing sleeve, and the bottom of the dust cover is provided with a dust removal hole connected to the air guide cavity.

[0008] In one of the embodiments, while retaining the existing lifting and rotating shooting functions, the adjustable camera mechanism is not only flexible in preventing dust, but also utilizes the lifting movement trend to self-clean the intercepted dust, so as to reduce the loss during the lifting, rotating or shooting process.

[0009] Furthermore, a circular hole is provided on the surface of the mounting shell, and an insertion cavity connected to the circular hole is provided inside the mounting shell, the angle adjustment assembly includes a rotating shaft and an adjustment block, the rotating shaft is rotatably connected to the inside of the circular hole, the two adjustment blocks are fixedly connected to the vertical inner wall of the mounting cavity, the surface of the rotating shaft is provided with a connecting cavity connected to the insertion cavity, the inside of the connecting cavity is fixedly connected with a spring piece plugged into the insertion cavity, both ends of the rotating shaft pass through circular holes, the surface of the rotating shaft is rotatably connected with a rotating seat fixedly connected to a threaded push plate, one end of the rotating shaft is fixedly connected to a guide block, the vertical cross-section of the guide block is a right triangle, and the inclined surface of the guide block is in contact with the corner of the adjustment block at this time.

[0010] In one of the embodiments, the angle adjustment component not only retains the function of rotating to adjust the angle of the camera module, but also when the mounting shell is subjected to external forces such as bumps on the surface of the mounting shell or the dust cover, the angle adjustment component can undergo elastic deformation by itself, so that the mounting shell drives the camera module to undergo corresponding elastic displacement, thereby preventing the mounting shell from being offset or twisted under the action of external forces, thereby ensuring that the camera module can operate normally.

[0011] Furthermore, the corners of the connecting cavity are rounded, and the distance between the rounded corner of the connecting cavity and the circular hole is greater than the thickness of the spring sheet.

[0012] In one embodiment, this can ensure that the spring sheet has sufficient space to deform, thereby preventing the spring sheet from being stuck between the circular hole and the rotating shaft.

[0013] Furthermore, the adjusting blocks are staggered with the rotating shaft, the number of the guiding blocks and the number of the adjusting blocks are both two, and the two guiding blocks and the two adjusting blocks are symmetrically distributed on both sides of the center point of the rotating shaft.

[0014] In one embodiment, this can make the rotation of the camera module more stable.

[0015] Furthermore, the vertical cross-section of the air guide cavity is in an inverted T-shape, and the lower opening of the air guide cavity is arranged between the circular hole and the elastic sealing sleeve.

[0016] In one embodiment, this can increase the air flow to improve the clean air flow.

[0017] Furthermore, a diversion channel connected to the air guide cavity and the dust removal holes is opened inside the dust cover, and the number of the dust removal holes is not less than ten; the dust removal holes are opened at the bottom of the dust cover around the outside of the mounting shell, and the lower opening of the dust removal holes faces the mounting shell.

[0018] In one embodiment, this can increase the cleaning area of ​​the air.

[0019] Furthermore, a dustproof net is fixedly connected to the bottom of the dustproof cover, and the top of the dustproof net covers the lower opening of the dust removal hole.

[0020] In one embodiment, this can filter dust mixed in the external air flow, so that the air sucked into the installation cavity is always kept clean.

[0021] Furthermore, a guide hole is opened at the top of the threaded push plate, a guide rod is inserted into the inside of the guide hole, both ends of the guide rod pass through the guide hole and are fixedly connected to the installation cavity, and the axis lines of the guide hole, guide rod and threaded column are all in a vertical state.

[0022] In one of the embodiments, this can reduce the probability that the threaded push plate rotates along with the threaded column, making the lifting and lowering of the threaded push plate more stable.

[0023] Furthermore, the gesture control system includes:

[0024] The gesture capture module uses an algorithm to identify the user's hand contour and track its movement trajectory, thereby capturing and identifying different gestures;

[0025] The gesture recognition module uses preset gestures and trains the model to recognize these gestures. When the user makes a corresponding gesture, it recognizes it as a corresponding control instruction;

[0026] The interactive control module, in combination with the operating system and application program of the tablet computer, responds to and executes gesture control instructions according to the user's gesture control instructions.

[0027] In the above-mentioned gesture-controlled smart tablet computer, the elastic sealing sleeve flexibly seals the gap between the mounting shell and the mounting cavity without affecting the normal entry and exit of the camera module into the mounting cavity, which can keep the structure inside the mounting cavity in a clean environment at all times, effectively reducing the loss of the structure inside the mounting cavity due to dust, thereby achieving a good protection effect;

[0028] At the same time, the threaded push plate can push the air inside the installation cavity during the rising process and actively guide it through the surface of the installation shell and the elastic sealing sleeve, which can not only blow away the dust adhering to the surface of the installation shell and the elastic sealing sleeve, and prevent a large amount of dust from being retained on the surface of the installation shell and the elastic sealing sleeve, but also when the air passes through the shooting position of the camera module, it can also automatically blow away the dust adhering to its surface, so that the camera module is always kept clean, so as to improve the clarity of the user's gesture shooting, thereby improving the accuracy of the user's gesture control;

[0029] Furthermore, the angle adjustment component not only has the function of rotating to adjust the angle of the camera module, but also can elastically deform by itself when the mounting shell is subjected to external forces such as bumps or other effects on the surface of the mounting shell or the dust cover, so that the mounting shell drives the camera module to undergo corresponding elastic displacement, thereby preventing the mounting shell from being offset or twisted under the action of external forces, thereby ensuring that the camera module can operate normally.

These modules enable the tablet computer 100 to easily access network resources and perform data transmission with other devices.

[0061] It should be noted that the display screen, housing, rear camera, buttons, interfaces, mainboard, battery, speaker, microphone sensor and wireless communication module described above are all devices with relatively mature application of existing technologies. The specific models can be selected according to actual needs and will not be elaborated here.

[0062] like Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7As shown, the adjustable camera mechanism 300 includes a micro servo motor 310 fixedly connected to the inner bottom wall of the mounting cavity 110, a threaded column 320 is fixedly connected to the top of the micro servo motor 310, a threaded push plate 330 is threadedly connected to the surface of the threaded column 320 and is slidably connected to the mounting cavity 110, an angle adjustment component 340 fixedly connected to the mounting cavity 110 is fixedly connected to the top of the threaded push plate 330, a mounting shell 350 is installed on the inner side of the angle adjustment component 340, a camera module 360 ​​is embedded and installed at one end of the mounting shell 350, an elastic sealing sleeve 370 fixedly connected to the mounting cavity 110 is sleeved on the surface of the mounting shell 350, a dust cover 380 is fixedly connected to the top of the mounting shell 350, an air guide cavity 351 is opened at the top of the mounting shell 350, the lower opening of the air guide cavity 351 is always arranged below the elastic sealing sleeve 370, and a dust removal hole communicating with the air guide cavity 351 is opened at the bottom of the dust cover 380 381; the vertical cross-section of the air guide cavity 351 is in an inverted T shape, and the lower opening of the air guide cavity 351 is arranged between the circular hole 352 and the elastic sealing sleeve 370; the dust cover 380 is provided with a shunt channel 382 connected to both the air guide cavity 351 and the dust removal holes 381, and the number of the dust removal holes 381 is not less than ten; the dust removal holes 381 are arranged around the outer side of the mounting shell 350 at the bottom of the dust cover 380, and the lower opening of the dust removal holes 381 faces the mounting shell 350 The bottom of the dust cover 380 is fixedly connected with a dust net 390, and the top of the dust net 390 covers the lower opening of the dust removal hole 381; the top of the threaded push plate 330 is provided with a guide hole 331, and the inside of the guide hole 331 is plugged with a guide rod 3100, and both ends of the guide rod 3100 pass through the guide holes 331 and are fixedly connected to the installation cavity 110, and the axis lines of the guide hole 331, the guide rod 3100 and the threaded column 320 are all in a vertical state;

[0063] When the user needs to raise or lower the camera module 360, the user controls the micro servo motor 310 through the tablet computer 100 to drive the threaded column 320 to rotate accordingly. The threaded column 320 drives the threaded push plate 330 to rise along the installation cavity 110 through the rotation. The threaded push plate 330 drives the installation shell 350 to rise through the angle adjustment component 340. The installation shell 350 drives the camera module 360 ​​to pass through the installation cavity 110 and the elastic sealing sleeve 370 in sequence until the guide block 344 and the adjustment block 345 just touch each other. At this time, the camera module 360 ​​can capture the user's gestures in real time.

[0064] like Figure 6 and Figure 7As shown, a circular hole 352 is provided on the surface of the mounting shell 350, and an inserting cavity 353 communicating with the circular hole 352 is provided inside the mounting shell 350. The angle adjustment assembly 340 includes a rotating shaft 341 and an adjusting block 345. The rotating shaft 341 is rotatably connected to the inside of the circular hole 352. The two adjusting blocks 345 are fixedly connected to the vertical inner wall of the mounting cavity 110. A connecting cavity 3411 communicating with the inserting cavity 353 is provided on the surface of the rotating shaft 341. The inside of the connecting cavity 3411 is fixedly connected with a spring piece 342 plugged into the inserting cavity 353. The circular holes 352 are passed through both ends of the rotating shaft 341. The surface of the rotating shaft 341 is rotatably connected with a spring piece 342 fixedly connected to the threaded push plate 330. The rotating seat 343 is fixedly connected, and one end of the rotating shaft 341 is fixedly connected with a guide block 344. The vertical cross-section of the guide block 344 is a right triangle. The inclined surface of the guide block 344 is in contact with the corner of the adjusting block 345 at this time. The elastic force of the spring 342 is always greater than the elastic force of the elastic sealing sleeve 370; the corners of the connecting cavity 3411 are rounded, and the distance between the rounded corner of the connecting cavity 3411 and the circular hole 352 is greater than the thickness of the spring 342; the adjusting block 345 is staggered with the rotating shaft 341, and the number of the guide blocks 344 and the adjusting blocks 345 are both two, and the two guide blocks 344 and the two adjusting blocks 345 are symmetrically distributed on both sides of the center point of the rotating shaft 341;

[0065] When the user needs to adjust the shooting angle of the camera module 360, the user only needs to continue to control the micro servo motor 310 to rotate in the original direction through the tablet computer 100, and the micro servo motor 310 continues to drive the threaded push plate 330 to move up along the installation cavity 110 through the threaded column 320, and the threaded push plate 330 drives the rotating shaft 341 to rise through the rotating seat 343, and the rotating shaft 341 drives the guide block 344 to rise, and the guide block 344 rotates along the adjusting block 345 under the obstruction of the adjusting block 345, and the guide block 344 drives the rotating shaft 341 to rotate, and the rotating shaft 341 drives the installation shell 350 to rotate through the spring piece 342, and the installation shell 350 drives the camera module 360 ​​to rotate, which can ensure that the camera module 360 ​​is adjusted to the corresponding angle to meet the user's gesture control interaction needs at different angles;

[0066] When an external force is applied to the surface of the mounting shell 350, the mounting shell 350 drives the camera module 360 ​​to rotate along the surface of the rotating shaft 341 by squeezing the spring piece 342, so that it has enough space for rotation buffering, thereby preventing the mounting shell 350 from being offset or twisted under the action of external force, thereby ensuring that the camera module 360 ​​can operate normally.

[0067] like Figure 8As shown, the gesture control system 200 includes: a gesture capture module 210, which can receive the user gesture pictures taken by the camera module 360 ​​in real time, and recognize the user's hand contour through an algorithm and track its movement trajectory, so as to realize the capture and recognition of different gestures; a gesture recognition module 220, which recognizes these gestures through pre-set gestures and training models. When the gesture capture module 210 captures and recognizes the user making a corresponding gesture, it recognizes it as a corresponding control instruction; an interactive control module 230, in combination with the operating system and application of the tablet computer 100, realizes the response and execution of gesture control instructions according to the user's gesture control instructions.

[0068] Working principle: When the mounting shell 350 drives the camera module 360 ​​to rise or fall or rotate, the elastic sealing sleeve 370 can flexibly seal the gap between the mounting shell 350 and the mounting cavity 110. Under the premise of ensuring that the mounting shell 350 can rotate or rise normally, this can prevent external dust from falling into the interior of the mounting cavity 110, so that the structure inside the mounting cavity 110 is always in a clean environment, effectively reducing the loss of the structure inside the mounting cavity 110 due to dust, thereby achieving a good protection effect;

[0069] During the rising process of the threaded push plate 330, the threaded push plate 330 pushes the air inside the installation cavity 110 upwards. Due to the gap between the flexible sealing sleeve 370 and the installation cavity 110, the upward air cannot be discharged through the opening of the installation cavity 110. At this time, the air can only enter the air guide cavity 351 along the lower opening of the air guide cavity 351. The air guide cavity 351 guides the air into the diversion channel 382. The diversion channel 382 guides the air into the dust removal hole 381 respectively. The air passes through the dust removal hole 381 and is discharged by the air. The air flows from top to bottom along the surface of the mounting shell 350, which can not only blow away the dust adhered to the surface of the mounting shell 350 and the elastic sealing sleeve 370, but also prevent a large amount of dust from being retained on the surface of the mounting shell 350 and the elastic sealing sleeve 370, thereby reducing the resistance to the lifting or rotation of the mounting shell 350. At the same time, when the air passes through the shooting point of the camera module 360, it can also blow away the dust adhered to its surface by itself, so that the camera module 360 ​​always remains clean, thereby improving the clarity of the user's gesture shooting, thereby improving the accuracy of the user's gesture control.

[0070] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0071] The above-described embodiments only express several implementation methods of the present invention, and the description thereof is relatively specific and detailed, but it cannot be understood as limiting the scope of the present invention. It should be pointed out that, for a person of ordinary skill in the art, several modifications and improvements can be made without departing from the concept of the present invention, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the present invention shall be subject to the attached claims.
