Description

Technical Field

[0001] This invention relates to the field of monitor mounting bracket technology, and more specifically to a monitor tilt adjustment component. Background Technology

[0002] Existing monitor stands, designed to meet user needs, offer both upward and downward viewing positions. This is achieved through a panel assembly, a rotating head, and an adjustment mechanism between the panel assembly and the rotating head. When the monitor is mounted on the panel assembly, adjusting to an upward viewing position requires the user to exert frictional resistance and utilize the monitor's weight, making adjustment difficult. Conversely, adjusting to a downward viewing position is easier due to the monitor's weight. This significant difference in the user's adjustment effort negatively impacts the user experience. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of the prior art and provide a display tilt adjustment component.

[0004] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0005] A display tilt adjustment assembly includes a rotating head seat mounted on a support, a panel assembly for mounting the display, and an adjustment structure disposed between the rotating head seat and the panel assembly. The adjustment structure includes a positioning member, a clamping member, and a friction member. The positioning member has an outer wall and an inner wall, with a receiving space between the outer and inner walls. The friction member is at least partially engaged within the receiving space. The inner wall has an outer surface and an inner surface opposite to the outer surface. The clamping member is engaged within the positioning member and abuts against the inner surface, thereby... The outer surface of the inner wall is in frictional contact with the friction member. The display tilt adjustment assembly has a tilting state and a tilting state. The rotating head is rotatably connected to the panel assembly around a first axis, thereby switching between the tilting state and the tilting state. When switching to the tilting state, the positioning member, the friction member, the clamping member and the panel assembly rotate in the same direction. When switching to the tilting state, the positioning member, the clamping member and the panel assembly rotate in the same direction. A one-way mechanism is provided between the friction member and the rotating head to restrict the rotation of the friction member relative to the rotating head.

[0006] In one embodiment, the positioning member includes a sidewall extending in a vertical direction, an outer wall extending in a horizontal direction, and an inner wall extending in a horizontal direction, wherein one end of the outer wall and one end of the inner wall in the horizontal direction are respectively connected to the sidewall.

[0007] In one embodiment, the sidewall has a circular cross-section, the outer wall has a cross-section that is an annulus formed with the center of the circle as the center, and the inner wall has a cross-section that is an arc formed with the center of the circle as the center.

[0008] In one embodiment, there are two arcs, and two notches are formed between the two arcs. The clamping member is provided with two protrusions that are respectively engaged in the two notches.

[0009] In one embodiment, the one-way mechanism includes a one-way gear and a helical gear that meshes with the one-way gear. A linkage structure is provided between the one-way gear and the friction member to cause the one-way gear to rotate synchronously with the friction member around the first axis. The helical gear is rotatably connected to the rotating head seat around the second axis. An elastic member is also provided between the helical gear and the rotating head seat to cause the helical gear to rotate around the second axis in a direction tending towards the one-way gear.

[0010] In one embodiment, when switching to the upward view, the positioning member, the friction member, the clamping member, the one-way gear, and the panel assembly rotate in the same direction; when switching to the downward view, the friction member and the one-way gear are fixed relative to the rotating head seat.

[0011] In one embodiment, the first axis extends in a left-right direction, and / or the second axis extends in a left-right direction, and / or the first axis and the second axis are arranged in parallel.

[0012] In one embodiment, the linkage structure comprises one or more holes formed on one of the friction member and the one-way gear, and one or more protrusions provided on the other of the friction member and the one-way gear, wherein the protrusions are engaged in the holes.

[0013] In one embodiment, a mating structure is provided between the panel assembly and the positioning member, the mating structure being a mating groove provided on one of the panel assembly and the positioning member, and a mating protrusion provided on the other of the two.

[0014] In one embodiment, the display tilt adjustment assembly further includes a connector that passes sequentially through the panel assembly, the positioning member, and the clamping member in a left-right direction.

[0015] In one embodiment, the positioning member includes a left positioning member and a right positioning member, the clamping member includes a left clamping member and a right clamping member, the friction member includes a left friction member and a right friction member, and the one-way mechanism cooperates with the left friction member and the right friction member respectively to synchronously restrict the rotation of the left friction member and the right friction member relative to the rotating head seat.

[0016] Due to the application of the above technical solution, the present invention has the following advantages compared with the prior art: The display tilt adjustment component of the present invention, by setting a one-way mechanism, makes it so that when adjusted to the tilt position, the positioning component, friction component and clamping component rotate synchronously, and the user needs to overcome the gravity of the display but does not need to output the frictional resistance between the friction component and the positioning component. When adjusted to the top position, the friction component and the positioning component do not rotate synchronously, and the user needs to overcome the frictional resistance between the friction component and the positioning component with the help of the gravity of the display. This makes adjusting to the tilt position easier and reduces the difference between the output force value of adjusting to the tilt position and adjusting to the top position, thus improving the user experience.

Detailed Implementation

[0025] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] In the description of this invention, the directions such as "front," "back," "left," "right," "up," and "down" are defined with reference to the directions observed by the user during use, i.e., as shown in the figure below. Figure 2 As shown in the figure, the left direction is "front", the right direction is "back", the upper direction is "up", the lower direction is "down", and the direction perpendicular to the viewpoint is "left" and "right". The above definitions of directions are only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] See Figure 1-6 The display tilt adjustment assembly of the present invention includes a rotating head seat 1 disposed on a support base (not shown in the figure), a panel assembly 2 for mounting a display (not shown in the figure), and an adjustment structure disposed between the rotating head seat 1 and the panel assembly 2.

[0028] The head mount 1 and the panel assembly 2 are rotatably connected about a first axis extending in the left-right direction, thereby adjusting the tilt angle between the head mount 1 and the panel assembly 2 to provide a comfortable viewing experience for the user. The adjustment structure provides friction for the rotatable connection between the head mount 1 and the panel assembly 2, allowing the panel assembly 2 to remain at the angle required by the user. Specifically, the monitor tilt adjustment component has a tilting state, a downward state, and a level state, such as... Figure 2 As shown, when viewed at eye level, the cross-section of panel assembly 2 extends vertically in the vertical direction, as... Figure 3 As shown, when viewed from below, the cross-section of panel assembly 2 extends upwards and slopes from front to back, as... Figure 4 As shown, when viewed from above, the cross-section of panel assembly 3 extends downwards from front to back.

[0029] The adjustment structure includes positioning components, friction components, clamping components, and connecting components.

[0030] The positioning element includes a sidewall 33 extending vertically, an outer wall 34 extending horizontally, and an inner wall 35 extending horizontally. One end of the outer wall 34 and the inner wall 35 in the horizontal direction is connected to the sidewall 33. The sidewall 33 has a circular cross-section, the outer wall 34 has a cross-section that is an annulus centered on the center of the circle, and the inner wall 35 has a cross-section that is an arc centered on the center of the circle. The outer wall 34 is disposed around the inner wall 35, and a receiving space 36 is formed between the outer wall 34 and the inner wall 35. The outer wall 34 has an outer surface 341 and an inner surface opposite to the outer surface 341. The inner wall 35 has an outer surface. The inner wall has a surface 351 and an inner wall surface 352 that is opposite to the outer inner wall surface 351. The outer inner wall surface 351 and the inner outer wall surface enclose the receiving space 36. The inner inner wall surface 352 encloses the clamping space 37 for accommodating the clamping member. The positioning member is placed in the rotating head seat 1, and the outer outer wall surface 341 is close to the inner cavity 111 of the rotating head seat 1. A mating structure is provided between the panel assembly 2 and the positioning member. The mating structure is a mating groove provided on one of the panel assembly 2 and the positioning member, and a mating protrusion 38 provided on the other. By providing the mating structure, the positioning member can rotate synchronously with the panel assembly 2 around the first axis.

[0031] The friction member 43 has a friction member sidewall and a friction member extension 44. The friction member sidewall 43 extends in the vertical direction and has a circular cross-section. The cross-section of the friction member extension 44 is an annulus formed with the center of the cross-section of the friction member sidewall 43 as the center. The friction member extension 44 extends in the horizontal direction. One end of the horizontal extension 44 is connected to the friction member sidewall 43, and the other end is engaged in the receiving space 36 enclosed by the outer wall 34 and the inner wall 35 of the positioning member. That is, at least part of the friction member is engaged in the receiving space 36.

[0032] The clamping member is disposed within the locking space 37 and located between the friction member and the positioning member. The clamping member has an outer surface 53 that abuts against the inner surface 352 of the inner wall of the positioning member, thereby causing the inner wall 35 to be opened from the inside out and causing the outer surface 351 of the inner wall to rub against the friction member. In this embodiment, both the outer surface 53 of the clamping member and the inner surface 352 of the inner wall gradually expand and extend from the outside to the inside in the left-right direction, so that the clamping member can be tightly locked in the locking space 37. In other embodiments, the outer surface 53 of the clamping member and the inner surface 352 of the inner wall can be set to be parallel to the first axis. A synchronization structure is also provided between the clamping member and the positioning member. Specifically, in this embodiment, the synchronization structure is a notch 39 and a protrusion 54. There are two arcs, and two notches 39 are formed between the two arcs. The clamping member is provided with two protrusions 54 that are respectively locked in the two notches 39. Through the cooperation of the notch 39 and the protrusion 54, the clamping member and the positioning member can rotate synchronously around the first axis.

[0033] A one-way mechanism is provided between the friction element and the rotating head seat 1 to restrict the rotation of the friction element relative to the rotating head seat 1. The one-way mechanism includes a one-way gear 6 and a helical gear 7 that meshes with the one-way gear 6. The helical gear 7 is rotatably connected to the rotating head seat 1 around a second axis. The second axis extends in the left-right direction and is parallel to the first axis. An elastic element is also provided between the helical gear 7 and the rotating head seat 1 to cause the helical gear 7 to rotate around the second axis in a direction tending towards the one-way gear 6. In this embodiment, the elastic element is a torsion spring 8. One end of the torsion spring 8 stops on the rotating head seat 1, and the other end stops on the helical gear 7. The helical gear 7 is located below the one-way gear 6, and the torsion spring 8 provides an elastic force to cause the helical gear 7 to rotate clockwise upward around the second axis. A linkage structure is provided between the one-way gear 6 and the friction member to enable the one-way gear 6 to rotate synchronously with the friction member around the first axis. The linkage structure consists of one or more holes 45 opened on one of the friction member and the one-way gear 6 and one or more protrusions 61 provided on the other of the friction member and the one-way gear 6. The protrusions 61 are engaged in the holes 45. In this embodiment, three holes 45 are opened on the side wall 43 of the friction member, and the one-way gear 6 has three protrusions 61 that cooperate with the three holes 45.

[0034] The connector passes sequentially through the panel assembly 2, the positioning component, and the clamping component in the left-right direction. The connector is specifically a bolt, and the clamping component has threads that mate with the bolt. The connector ensures that the clamping component can be tightly engaged in the clamping space 37 in the left-right direction, thereby further ensuring frictional contact between the outer surface 351 of the inner wall of the positioning component and the friction component.

[0035] In this embodiment, the positioning components include a left positioning component 31 and a right positioning component 32; the clamping components include a left clamping component 51 and a right clamping component 52; the friction components include a left friction component 41 and a right friction component 42; and the connecting components include a left connecting component 91 and a right connecting component 92. The panel assembly has a left mating groove 21 that mates with the left positioning component 31 and a right mating groove 22 that mates with the right positioning component 32. The left connecting component 91 passes sequentially through the left side of the panel assembly 2, the left positioning component 31, and the left clamping component 51. The right connecting component 92 passes sequentially through the right side of the panel assembly 2, the right positioning component 32, and the right clamping component 52. In other embodiments, only one set of positioning components, clamping components, friction components, and connecting components may be provided.

[0036] In this embodiment, the one-way mechanism cooperates with the left friction member 41 and the right friction member 42 respectively to synchronously restrict the rotation of the left friction member 41 and the right friction member 42 relative to the rotating head seat 1. That is, the left side of the one-way gear 6 is provided with a protrusion 61 that cooperates with the left friction member 41, and the right side of the one-way gear 6 is provided with a protrusion 61 that cooperates with the right friction member 42.

[0037] The working principle of the display tilt adjustment component of the present invention:

[0038] The rotating head 1 and the panel assembly 2 are rotatably connected around the first axis, thus switching between the upward and downward viewing positions. When switching to the upward viewing position, the panel assembly 2 is manually rotated clockwise. Due to the cooperation structure between the positioning component and the panel assembly 2, the positioning component and the panel assembly 2 rotate synchronously. Due to the synchronous structure between the positioning component and the clamping component, the clamping component and the positioning component rotate synchronously. Due to the friction contact between the inner wall outer surface 351 and the friction component, the friction component and the positioning component rotate in the same direction. Due to the linkage structure between the friction component and the one-way gear 6, the one-way gear 6 rotates synchronously with the friction component. The helical gear 7 is subjected to the downward force of the one-way gear 6 and rotates counterclockwise around the second axis to avoid it. The torsion spring 8 accumulates elastic force, and the torsion spring 8 rebounds to stop the further movement of the one-way gear 6. When rotating clockwise, i.e., changing to a looking-up position, the user needs to resist gravity and the elastic force of the torsion spring 8. When changing to a looking-down position, the user manually operates the panel assembly 2 to rotate counterclockwise. Due to the cooperation structure between the positioning member and the panel assembly 2, the positioning member and the panel assembly 2 rotate synchronously. Due to the synchronous structure between the positioning member and the clamping member, the clamping member and the positioning member rotate synchronously. Due to the one-way mechanism between the friction member and the rotating head seat 2, the helical gear 7 prevents the one-way gear 6 from rotating counterclockwise. Due to the linkage structure between the one-way gear 6 and the friction member, the friction member cannot rotate counterclockwise, but is fixed relative to the one-way gear and the rotating head seat. That is, when changing to a looking-down position, although gravity can be used, the user needs to resist the friction between the inner wall outer surface 351 and the friction member.

They should not be construed as limiting the scope of protection of the present invention.
