Description

Technical Field

[0001] The present invention relates to the technical field of monitor arms, and more specifically, to a monitor arm with multi-angle fully automatic adjustment and locking based on face recognition. Background Art

[0002] The existing traditional monitor arm angle locking mechanism is composed of parts such as a return spring, a threaded screw rod, and a nut base structure, and together with other components such as the upper arm assembly of the arm, the lower arm assembly of the arm, and the rotating shaft connecting rod, it constitutes the arm locking mechanism, which is widely used in the monitor arm angle adjustment and locking system function.

[0003] The monitor adjustment and locking mechanism usually adopts the threaded screw rod of the upper arm assembly of the arm (the threaded screw rod is used as the locking mechanism of the structure), and the nut base of the lower arm assembly of the arm (the nut base is used as the fixed support base of the structure). When the arm needs to be locked and fixed, the upper arm assembly of the arm is pressed downward, so that the threaded screw rod of the assembly screws into the nut base of the lower arm assembly of the arm through the compression of the return spring, aligns with the threaded hole, and tightens the threaded screw rod of the upper arm assembly of the arm to achieve the state and function of fixing and locking the relative position and angle between the upper arm assembly of the arm and the lower arm assembly of the arm.

[0004] However, the above operations are all achieved through manual adjustment, and there is no locking setting, lacking artificial intelligence design, and being complex, inconvenient, and time-consuming. It is necessary to fully screw the threaded screw rod into the nut base to ensure firm and reliable fixing and locking; and the threaded screw rod is directly exposed within the sight range of human eyes, which not only affects the aesthetics but also reduces the product grade; moreover, due to threaded fastening, repeated tightening and disassembly easily damage the threaded connection between the threaded screw rod and the nut base, causing it to loosen and affecting the product reliability. Most seriously, after the threaded connection fails, the locking and fixing function is lost, causing the upper arm assembly of the arm to suddenly lift, thus threatening the safety of the user. Therefore, it is necessary to propose an upper arm locking device for a monitor arm to at least partially solve the problems existing in the prior art.

[0042] Working principle and beneficial effects of the above technical solution: The present invention provides a display arm with multi-angle fully automatic adjustment and locking based on face recognition. The display arm with multi-angle fully automatic adjustment and locking based on face recognition includes: an arm main body 100, where the arm main body 100 includes a rotating base 1, an upper arm assembly 2, and a lower arm assembly 3. The lower arm assembly 3 is movably installed on the rotating base 1, and the upper arm assembly 2 is movably installed on the lower arm assembly 3. A locking mechanism 4 is installed in the upper arm assembly 2, a control module 5 is installed in the lower arm assembly 3, and a face recognition module 6 is installed in the rotating base 1. Therefore, when adjusting the display arm, the control module 5 installed in the lower arm assembly 3 is activated, so that the face recognition module 6 is powered on and activated. Furthermore, the face recognition module 6 can track the user's face. Then the control module 5 can activate the upper arm assembly 2 to perform a circumferential rotation horizontally relative to the lower arm assembly 3, or activate the upper arm assembly 2 to swing up and down relative to the lower arm assembly 3. Thus, the display installed on the upper arm assembly 2 can always correspond to the user's face, making the adjustment of the display arm more automated, saving time and effort. At the same time, when the display arm needs to be locked and folded, the user can adjust the upper arm assembly 2 to be close to the lower arm assembly. Then the locking mechanism 4 installed in the upper arm assembly 2 can lock the upper arm assembly 2 from the inside, so that the upper arm assembly 2 cannot swing up and down relative to the lower arm assembly 3. Therefore, it is convenient to transport the display arm.

[0043] It can be understood that the face recognition module 6 is set as an intelligent camera.

[0044] In one embodiment, the upper arm assembly 2 includes a first upper arm member 21, a second upper arm member 22, a connecting rod cylinder 23, and a display fixing member 24. Two hinge plates 25 are provided on the connecting rod cylinder 23. One end of the first upper arm member 21 is hinged to the upper end of the hinge plate 25.

The display fixing member 24 is hinged to the other ends of the first upper arm member 21 and the second upper arm member 22, so that the upper arm assembly 2 forms a four-bar frame similar to a parallelogram. By starting the inner positioning member 26 through the control module 5, the inner positioning member 26 can act, and then the first upper arm member 21 and the second upper arm member 22 can rotate up and down on the connecting rod cylinder 23, and then the upper arm assembly 2 can rotate up and down. Thus, the display fixing member 24 can be lifted upward or moved downward. Among them, an inner positioning member is provided in the first upper arm member 21, and the first upper arm member 21 can be fixed relative to the connecting rod cylinder 23 through the inner positioning member 26, that is, the hovering of the upper arm assembly 2 is realized.

[0046] In one embodiment, the inner positioning member 26 includes a first bracket 27, a second bracket 28, and an electric telescopic rod 29. The first bracket 27 is arranged on the connecting rod cylinder 23 and is connected to the hinge plate 25. The second bracket 28 is arranged on the inner wall of the first upper arm member 21. The electric telescopic rod 29 is arranged between the first bracket 27 and the second bracket 28 and is electrically connected to the control module 5.

The inner positioning member of this structure includes an electric telescopic rod 29, a first bracket 27, and a second bracket 28. Among them, the first bracket 27 is installed on the connecting rod cylinder 23 and is connected to the hinge plate 25, while the second bracket 28 is installed on the inner wall of the first upper arm member 21. The electric telescopic rod 29 is installed between the first bracket 27 and the second bracket 28. Therefore, when the upper arm assembly 2 needs to rotate up and down, the electric telescopic rod 29 is controlled by the control module 5 to extend or shorten, so that the electric telescopic rod 29 supports the first upper arm member 21, so that the first upper arm member 21 can hover at any angle relative to the connecting rod cylinder 23, and then the position adjustment of the entire upper arm assembly 2 is realized, which is convenient for use.

[0051] Working principle and beneficial effects of the above technical solution: In this embodiment, components such as a second motor 11, a first fixing bracket 12, and a first coupling 13 are designed in the rotating base 1. Here, the first fixing bracket 12 is installed in the rotating base 1, and the second motor 11 is installed on the first fixing bracket 12. A first coupling 13 is installed on the output shaft of the second motor 11, so that the lower arm shaft 302 of the lower arm assembly 3 extends into the rotating base 1. The lower end of the lower arm shaft 302 is connected to the first coupling 13, and a second locknut 111, a second disc spring 112, a second wear-resistant gasket 113, and a first double-row angular contact ball bearing 114 are installed on the lower arm shaft 302.

The locking assembly 42 is arranged on the second upper arm member 22 and is used to lock the middle plate 412 of the upper adjusting plate member 41.

[0055] Working principle and beneficial effects of the above technical solution: In this embodiment, the specific structure of the upper adjusting plate member 41 is provided. The upper adjusting plate member 41 of this structure is designed to be U-shaped. The upper adjusting plate member 41 includes a middle plate 412 and two upper side wall plates 81. The two upper side wall plates 81 are installed on both sides of the middle plate 412. The upper side wall plates 81 are connected to the inner wall of the first upper arm member 21, so that the middle plate 412 faces the locking assembly 42.

[0056] In one embodiment, the locking assembly 42 includes a positioning pin 421, a support spring 422, a button base 423, and a knob cover 424. The button base 423 is disposed at the bottom of the second upper arm member 22. The positioning pin 421 is inserted into the button base 423. The knob cover 424 is disposed at the lower end of the positioning pin 421. The support spring 422 is disposed on the positioning pin 421 and is located between the knob cover 424 and the second upper arm member 22.

The diameter of the second shaft platform 426 is larger than that of the first shaft platform 425, and the first shaft platform 425 corresponds to the adjustment hole 413. A bushing 427 is provided on the button base 423, and the positioning pin 421 is inserted into the bushing 427.

[0057] Working principle and beneficial effects of the above technical solution: In this embodiment, an adjustment hole 413 is formed in the intermediate plate 412.

The diameter of the second shaft platform 426 is larger than that of the first shaft platform 425, and the first shaft platform 425 corresponds to the adjustment hole 413. When installing the positioning pin 421 and the adjustment hole 413, an operator's finger forcefully pushes the knob cover 134 upward, then the first shaft platform 425 on the positioning pin 421 passes through the adjustment hole 413. Since the diameter of the second shaft platform 426 is larger than that of the first shaft platform 425 and the diameter of the second shaft platform 426 is larger than the adjustment hole 413, the second shaft platform 426 cannot pass through the adjustment hole 413, such that the second shaft platform 426 is located below the intermediate plate 412. Therefore, when pressing the adjustment upper arm assembly 2 downward, the upper adjustment plate member 41 in the first upper arm member 21 moves upward relative to the locking assembly 42. In this way, the positioning pin 421 moves from the elongated hole 414 in the adjustment hole 413 to the circular hole 415. Due to the action of the support spring 132, the second shaft platform 426 abuts against the inner wall of the first upper arm member 21. At this time, the first shaft platform 425 moves into the circular hole 415, and the circular hole 415 clamps the first shaft platform 425, thereby achieving the fixation between the first upper arm member 21 and the second upper arm member 22.

[0058] The adjustment hole 413 here includes an oblong hole 414 and a round hole 415. When it is necessary to move the upper arm assembly 2 upward, the operator uses a finger to push the knob cover 134 upward. In this way, the first shaft platform 425 stuck in the round hole 415 disengages from the round hole 415, enabling the positioning pin 421 to enter the round hole 415. As the upper arm assembly 2 moves upward, the positioning pin 421 enters the oblong hole 414 from the round hole 415. At this time, the first shaft platform 425 is located above the oblong hole 414, and the second shaft platform 426 is located below the oblong hole 414. Due to the action of the support spring 132, the first shaft platform 425 presses downward against the upper surface of the middle plate 412. Since the upper arm assembly 2 is provided with an internal positioning member, the upper arm assembly 2 can be hovered.

[0059] In order to further facilitate the movement of the positioning pin 421 in the adjustment hole 413, in this embodiment, a bushing 427 is provided on the button base 133. The positioning pin 421 is inserted through the bushing 427. In this way, the positioning pin 421 can move up and down in the bushing 427 conveniently, reducing the friction between the positioning pin 421 and the button base 133, improving wear resistance, and making the positioning pin 421 operate more smoothly.

[0060] In one embodiment, a display swing part 20 is further provided at the front end of the display fixing part 24. The display swing part 20 includes a swing motor 201. The swing motor 201 is arranged in the rotary upper cover 244. Two output shafts are provided on the swing motor 201. The output shafts are connected to a swing rod 203 through a fourth coupling 202. A fourth anti-slip gasket 204, a fourth butterfly gasket 205, an L-shaped fixing plate 206, and a fourth locknut 207 are provided on the swing rod 203. The fourth locknut 207 presses against the L-shaped fixing plate 206 through the fourth anti-slip gasket 204 and the fourth butterfly gasket 205. The two L-shaped fixing plates 206 are connected to the display.

[0061] Working principle and beneficial effects of the above technical solution: In this embodiment, a display swing part 20 is further provided at the front end of the display fixing part 24. Here, the display swing part 20 includes a swing motor 201, and the swing motor 201 is installed inside the front end of the rotary upper cover 244. Two output shafts are designed on the swing motor 201. Here, the two output shafts are respectively connected to the swing rod 203 through the fourth coupling 202. An L-shaped fixing plate 206 is installed on the swing rod 203. In this way, the display can be connected through the two L-shaped fixing plates 206. To increase firmness, a fourth anti-slip gasket 204, a fourth butterfly gasket 205, and a fourth locknut 207 are also installed on the swing rod 203. In this way, the fourth anti-slip gasket 204 and the fourth butterfly gasket 205 are abutted against the L-shaped fixing plate 206 by the fourth locknut 207, and the L-shaped fixing plate 206 is fixed to the swing rod 203. Therefore, when the user wants to adjust the angle of the display, the user can swing the head up and down. In this way, the face recognition module 6 can capture the swing of the user's head, and then the control module 5 starts the swing motor 201. The output shaft of the swing motor 201 drives the swing rod 203 to rotate, and then drives the L-shaped fixing plate 206 to swing synchronously, thereby realizing the adjustment of the front and rear elevation angles of the display, which is convenient for the user to use.

The outer end of the first compression spring 346 is connected to the second retaining cap 352.

[0063] The working principle and beneficial effects of the above technical solution: In this embodiment, the specific structure of the inner lifting module 31 is provided. The inner lifting module 31 of this structure includes a lifting cylinder 32, a push block seat 33, a plurality of outer lifting seats 34, and a lifting stroke assembly 35. Here, the lifting cylinder 32 is installed within the electric cylinder 291, and the push block seat 33 is installed at the inner end of the lifting cylinder 32. An inner threaded hole 331 is provided within the push block seat 33. Therefore, the wire lever 28 can rotatably pass through the inner threaded hole 331 of the push block seat 33. The lower end of the inner push rod 294 is connected to the push block seat 33. Through the push block seat 33, the rotation connection between the entire inner lifting module 31 and the wire lever 28 is realized, avoiding the threaded connection method between the wire lever 28 and the inner wall of the inner push rod 294 in the prior art and reducing the rotation resistance.

[0064] To prevent the inner lifting module 31 from wobbling when lifting in the electric cylinder 291 and to increase its flexibility during lifting in the electric cylinder 291, multiple outer lifting seats 34 are evenly distributed on the outer wall of the lifting cylinder 32. The multiple outer lifting seats 34 are slidably connected to the inner wall of the electric cylinder 291.

[0065] The outer lifting seat 34 includes an outer seat body 341 and two lifting wheel sets.

First baffles 347 are respectively arranged at both ends of the push shaft body 345. The first baffles 347 provide protection for the first compression springs 346. Here, the inner end of the first compression spring 346 is connected to the outer wall of the lifting cylinder 32 through a first cap 348. At the same time, the outer end of the first compression spring 346 is connected to a second cap 352 on the inner push rod 350, so that the first compression spring 346 pushes the push shaft body 345 through the inner rod 350 and the push ring 349, causing the push shaft body 345 to move to the end of the push slot hole 343. The lifting wheel body 344 is partially located outside the inner sliding cavity 342 and contacts the inner wall of the electric cylinder 291. Therefore, the lifting wheel body 344 can rotate along the outer wall of the inner wall of the electric cylinder 291, making the lifting of the entire lifting cylinder 32 more stable and preventing wobbling, increasing flexibility. In this way, the lifting of the upper arm assembly of the entire display arm relative to the lower arm assembly is more stable.

[0066] In one embodiment, the lifting stroke assembly 35 is arranged on the outer wall of the lifting cylinder 32 and is located below the outer lifting seat 34. The lifting stroke assembly 35 includes a positioning ring 36, multiple stroke rods 37, and multiple C-shaped positioning plates 38. The multiple stroke rods 37 are evenly arranged on the outer wall of the lifting cylinder 32. A notch groove 361 corresponding to the stroke rod 37 is formed on the inner wall of the positioning ring 36. Multiple convex grooves 362 are formed on the outer peripheral wall of the positioning ring 36. A convex inner plate 381 is formed on the inner wall of the C-shaped positioning plate 38.
