[0002] This disclosure claims priority to Chinese patent application number 2024100510807, filed with the Chinese Patent Office on January 12, 2024, entitled “A Display Pitch Adjustment Component,” the entire contents of which are incorporated herein by reference. Technical Field

[0003] The present disclosure relates to the technical field of display mounting brackets, and in particular to a display pitch adjustment assembly. Background Art

[0004] In order to meet the usage needs of users, the display stand in the prior art has an upward-looking state and a downward-looking state. Specifically, the conversion between the upward-looking state and the downward-looking state is achieved by setting a panel assembly, a swivel seat and an adjustment structure set between the panel assembly and the swivel seat. After the panel assembly is assembled with the display, when it needs to be adjusted to the upward-looking state, the user needs to output friction resistance and the gravity of the display, which makes the adjustment very laborious. When it needs to be adjusted to the downward-looking state, the adjustment is easier due to the help of the gravity of the display, resulting in a large difference in the output force value when the user adjusts, affecting the usage experience.

[0027] The technical solution of the present disclosure is further described below with reference to the accompanying drawings and specific embodiments.

[0028] In the description of the present disclosure, the directions involved, such as "front", "back", "left", "right", "up" and "down", are all defined with reference to the directions observed by the user during use, that is, as shown in FIG2 , the left direction in the figure is "front", the right direction in the figure is "back", the upper direction in the figure is "up", the lower direction in the figure is "down", and the directions perpendicular to the viewing angle in the figure are "left" and "right". The definitions of the above directions are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present disclosure.

[0029] 1-6 , the display pitch adjustment assembly disclosed herein includes a turntable base 1 disposed on a support base (not shown in the figures), a panel assembly 2 configured to mount a display (not shown in the figures), and an adjustment structure disposed between the turntable base 1 and the panel assembly 2.

[0030] The swivel head mount 1 and the panel assembly 2 are rotatably connected around a first axis extending in the left-right direction, thereby adjusting the pitch angle between the swivel head mount 1 and the panel assembly 2 to provide a comfortable viewing experience for the user. The adjustment structure provides friction for the rotational connection between the swivel head mount 1 and the panel assembly 2, so that the panel assembly 2 can stay at the angle required by the user. Specifically, the display pitch adjustment assembly has an upward-looking state, a downward-looking state, and a horizontal-looking state. As shown in FIG2 , when in the horizontal-looking state, the cross-section of the panel assembly 2 extends vertically in the up-down direction. As shown in FIG3 , when in the upward-looking state, the cross-section of the panel assembly 2 extends upwardly and tiltedly from front to back. As shown in FIG4 , when in the downward-looking state, the cross-section of the panel assembly 3 extends downwardly and tiltedly from front to back.

[0031] The adjusting structure includes a positioning member, a friction member, a clamping member, and a connecting member.

[0032] The positioning member includes a side wall 33 extending in the up-down direction, an outer wall 34 extending in the left-right direction, and an inner wall 35 extending in the left-right direction. The outer wall 34 and the inner wall 35 are connected to the side wall 33 at one end in the left-right direction. The cross section of the side wall 33 is circular. The cross section of the outer wall 34 is a ring formed with the center of the circle as the center. The cross section of the inner wall 35 is an arc formed with the center of the circle as the center. The outer wall 34 is arranged on the periphery of the inner wall 35. A receiving space 36 is provided between the outer wall 34 and the inner wall 35. The outer wall 34 has an outer wall outer surface 341 and an outer wall inner surface arranged opposite to the outer wall outer surface 341. The inner wall 35 has an inner wall outer surface. The surface 351 and the inner surface 352 of the inner wall are arranged opposite to the outer surface 351 of the inner wall. The outer surface 351 of the inner wall and the inner surface of the outer wall are arranged to form the accommodating space 36. The inner surface 352 of the inner wall is arranged to form a clamping space 37 configured to accommodate the clamping member. The positioning member is placed in the turntable seat 1, and the outer surface 341 of the outer wall is close to the inner cavity 111 of the turntable seat 1. A matching structure is provided between the panel assembly 2 and the positioning member. The matching structure is a matching groove provided on one of the panel assembly 2 and the positioning member, and a matching protrusion 38 provided on the other of the two. By setting the matching structure, the positioning member can rotate synchronously with the panel assembly 2 around the first axis.

[0033] The friction member 43 has a friction member side wall and a friction member extension portion 44. The friction member side wall 43 extends in the up-down direction, and the cross section of the friction member side wall 43 is circular. The cross section of the friction member extension portion 44 is a ring formed with the center of the cross section of the friction member side wall 43 as the center. The friction member extension portion 44 extends in the left-right direction, and one end portion thereof in the left-right direction is connected to the friction member side wall 43, and the other end portion is clamped in the accommodating 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 clamped in the accommodating space 36.

[0034] The clamping member is arranged in the clamping space 37 and is located between the friction member and the positioning member. The clamping member has an outer clamping member surface 53 that is in contact with the inner surface 352 of the inner wall of the positioning member, so that the inner wall 35 is stretched from the inside to the outside and the outer surface 351 of the inner wall is in friction contact with the friction member. In this embodiment, the outer clamping member surface 53 and the inner wall inner surface 352 are gradually expanded and extended from the outside to the inside in the left and right directions, so that the clamping member can be tightly clamped in the clamping space 37. In other embodiments, the outer clamping member surface 53 and the inner wall inner surface 352 can also 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 respectively clamped 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.

[0035] A one-way mechanism is provided between the friction member and the turret base 1 to limit the rotation of the friction member relative to the turret base 1. The one-way mechanism includes a one-way gear 6 and a helical gear 7 meshing with the one-way gear 6. The helical gear 7 is rotatably connected to the turret base 1 about a second axis. The second axis extends in the left-right direction and is arranged parallel to the first axis. An elastic member is also provided between the helical gear 7 and the turret base 1 to cause the helical gear 7 to rotate about the second axis toward the one-way gear 6. In this embodiment, the elastic member is a torsion spring 8. One end of the torsion spring 8 stops on the turret base 1, and the other end stops on the helical gear 7. The helical gear 7 is provided below the one-way gear 6. The torsion spring 8 provides an elastic force that causes the helical gear 7 to rotate upward and clockwise about 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 is one or more holes 45 provided 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 clamped in the holes 45. In this embodiment, three holes 45 are provided 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.

[0036] The connecting member, specifically a bolt, is sequentially inserted through the panel assembly 2, the positioning member, and the clamping member in the left-right direction. The connecting member is provided with threads that mate with the bolt. The arrangement of the connecting member allows the clamping member to be tightly engaged in the retaining space 37 in the left-right direction, thereby further ensuring frictional contact between the outer surface 351 of the inner wall of the positioning member and the friction member.

[0037] In this embodiment, the positioning members include a left positioning member 31 and a right positioning member 32, the clamping members include a left clamping member 51 and a right clamping member 52, the friction members include a left friction member 41 and a right friction member 42, and the connecting members include a left connecting member 91 and a right connecting member 92. The panel assembly has a left mating groove 21 that cooperates with the left positioning member 31 and a right mating groove 22 that cooperates with the right positioning member 32. The left connecting member 91 sequentially passes through the left side of the panel assembly 2, the left positioning member 31, and the left clamping member 51. The right connecting member 92 sequentially passes through the right side of the panel assembly 2, the right positioning member 32, and the right clamping member 52. In other embodiments, only one set of positioning members, clamping members, friction members, and connecting members may be provided.

[0038] In this embodiment, the one-way mechanism cooperates with the left friction member 41 and the right friction member 42 respectively to synchronously limit the rotation of the left friction member 41 and the right friction member 42 relative to the rotary 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.

[0039] The working principle of the display pitch adjustment assembly disclosed in the present invention is as follows:

[0040] The head seat 1 is connected to the panel assembly 2 by rotating around the first axis so as to switch between the upward-looking state and the downward-looking state. When switching to the upward-looking state, the panel assembly 2 is rotated clockwise by hand. Due to the existence of the matching structure between the positioning member and the panel assembly 2, the positioning member and the panel assembly 2 rotate synchronously. Due to the existence of the synchronous structure between the positioning member and the clamping member, the clamping member and the positioning member rotate synchronously. Since the outer surface 351 of the inner wall is in friction contact with the friction member, the friction member and the positioning member rotate in the same direction. Due to the linkage structure set between the friction member and the one-way gear 6, the one-way gear 6 rotates synchronously with the friction member. The bevel 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 one-way gear 6 from rotating further clockwise, that is, when switching to the upward-looking state, the user needs to fight against gravity and the elastic force of the torsion spring 8; when switching to the downward-looking state. When the state is changed, the panel assembly 2 is rotated counterclockwise by hand. Due to the matching structure between the positioning part and the panel assembly 2, the positioning part and the panel assembly 2 rotate synchronously. Due to the synchronization structure between the positioning part and the clamping part, the clamping part and the positioning part rotate synchronously. Due to the setting of the one-way mechanism between the friction part and the turntable seat 2, the bevel gear 7 prevents the one-way gear 6 from rotating counterclockwise. Due to the linkage structure set between the one-way gear 6 and the friction part, the friction part cannot rotate counterclockwise, but is relatively fixed with the one-way gear and the turntable seat. That is, when changing to the top-down state, although gravity can be used, the user needs to resist the friction between the outer surface 351 of the inner wall and the friction part.

[0041] The above embodiments are intended only to illustrate the technical concepts and features of the present disclosure. Their purpose is to enable those familiar with the art to understand the contents of the present disclosure and implement them accordingly. They are not intended to limit the scope of protection of the present disclosure. Any equivalent changes or modifications made in accordance with the spirit of the present disclosure are intended to be included in the scope of protection of the present disclosure. Industrial Applicability
