In addition, the present utility model provides examples of various specific processes and materials, but those of ordinary skill in the art can be aware of the application of other processes and / or the use of other materials.

[0056] Referring to Figure 1 and Figure 2 , in some embodiments of the present application, a TV wall-mounted bracket is provided, which includes a TV connection component 100, an arm component 200, and a wall connection component 300.

[0057] The TV connection component 100 faces the side where the user is located and is used to connect to the TV, specifically connected to the rear case of the TV.

[0058] The wall connection component 300 is close to the wall side and is used to connect to the wall.

[0059] The arm component 200 is extended and arranged between the TV connection component 100 and the wall connection component 300, and is used to connect the TV connection component 100 and the wall connection component 300, thereby mounting the TV on the wall and realizing the wall-mounted installation of the TV.

[0060] In some embodiments of the present application, referring to Figures 3 to 8 , and in combination with Figure 1 and Figure 2 , the TV connection component 100 includes a TV connection main body 110. The TV connection main body 110 is a structural component in the TV connection component 100 that directly contacts and connects to the rear case of the TV, and is the basic framework of the entire TV connection component 100.

[0061] As Figures 1 to 3 shown, the TV connection main body 110 includes two horizontally strip-shaped connecting plates 111 arranged up and down and two vertically strip-shaped connecting plates 112 arranged left and right. After the multiple connecting holes 113 on the vertically strip-shaped connecting plates 112 are aligned with the multiple connecting holes 113 on the rear case of the TV, the TV is mounted on the TV connection main body 110 through connection means such as screws and nuts passing through the vertically strip-shaped connecting plates 112.

[0062] The vertically strip-shaped connecting plates 112 can slide left and right relative to the horizontally strip-shaped connecting plates 111 and can be fixed in the position after sliding in place, so as to adjust the distance between the two vertically strip-shaped connecting plates 112 for adapting to the installation of TVs of different sizes.

[0063] As shown Figure 3 in the figure, sliding grooves 114 are respectively formed at the upper and lower ends of the vertical strip-shaped connecting plate 112. The sliding grooves 114 are sleeved and slidably engaged with the horizontal strip-shaped connecting plate 111. Fastening screws are provided at the groove openings. By loosening the fastening screws, the vertical strip-shaped connecting plate 112 can slide left and right, and by tightening the fastening screws, the vertical strip-shaped connecting plate 112 can be locked.

[0064] In some embodiments of the present application, as shown Figures 1 to 8 in the figure, the TV connection assembly 100 further includes a pitching adjustment mechanism 120. The pitching adjustment mechanism 120 is provided on the TV connection main body 110. The pitching adjustment mechanism 120 includes a pitching adjustment member 121, a first hinge member 122, and a positioning member 123. The pitching adjustment member 121 is rotatably connected to the first hinge member 122 around a horizontal axis. The positioning member 123 is used to lock the pitching adjustment member 121 after the pitching adjustment member 121 rotates in place. By driving the pitching adjustment member 121 to rotate relative to the first hinge member 122 around the horizontal axis, the pitching adjustment of the TV relative to the horizontal plane can be realized.

[0065] The first end of the arm assembly 200 is hinged to the first hinge member 122, and the second end of the arm assembly 200 is hinged to the wall connection assembly 300, and the hinge axes are all vertical axes. By rotating the arm assembly 200, the left and right position adjustment and the front and back position adjustment (i.e., the adjustment of the distance between the TV and the wall) of the TV relative to the wall can be realized, that is, the normal left and right position adjustment and the front and back position adjustment functions of the TV are ensured.

[0066] Therefore, the TV wall hanging bracket in some embodiments of the present application enriches the adjustment function of the TV position. It can not only realize the normal left and right position adjustment and the front and back position adjustment of the TV, but also realize the pitching adjustment, which can meet the needs of different users for watching TV and improve the market competitiveness.

[0067] In some embodiments of the present application, as shown Figure 1 and Figure 2 in the figure, two sets of arm assemblies 200 are symmetrically arranged left and right to form a double-arm structure. Correspondingly, two first hinge members 122 are provided, located on the left and right sides of the pitching adjustment member 121, and two corresponding hinge positions are also provided on the wall panel assembly; the double-arm structure of the arm assembly 200 has high support strength, safety and reliability.

[0068] Of course, the arm assembly 200 can also be provided with one set, that is, a single-arm structure, and no specific limitation is made here. Figures 1 to 7 Only the arm assembly 200 with a double-arm structure is taken as an example for illustration.

[0069] In some embodiments of the present application, two arc-shaped guiding portions 124 are arranged at intervals up and down at the connection positions of the pitching adjusting member 121 with each arm assembly 200, and one positioning member 123 is arranged and correspondingly arranged with one of the arc-shaped guiding portions 124. The first hinge member 122 and the other arc-shaped guiding portion 124 can be movably riveted by a rivet 125.

[0070] The gap between the first hinge member 122 and the pitching adjusting member 121 at the movably riveted position is small, which can satisfy that after the positioning force of the positioning member 123 is removed to unlock the pitching adjusting member 121, the pitching adjusting member 121 will not suddenly rotate and drop greatly relative to the first hinge member 122 due to the gravity of the TV itself, thus avoiding accidental damage to the TV; and a certain external force needs to be applied to the TV and then to the pitching adjusting member 121 to make it rotate slightly relative to the first hinge member 122 to realize the pitching adjustment function, ensuring that the connection reliability between the TV connection assembly 100 and the arm assembly 200 will not be affected during adjustment.

[0071] During pitching adjustment, the pitching adjusting member 121 rotates relative to the first hinge member 122 under the guiding action of the two arc-shaped guiding portions 124, making the adjustment of the pitching adjusting member 121 more flexible and with high adjustment accuracy, and enabling micro-angle adjustment.

[0072] For a TV wall-mounted bracket with two sets of arm assemblies 200 arranged left and right, it is also possible that only one of the arm assemblies 200 is rotatably connected to the pitching adjusting member 121 through a positioning member 123 and a movable riveting point, and the other arm assembly 200 is rotatably connected to the pitching adjusting member 121 through two movable riveting points. Then, during adjustment, only this positioning member 123 needs to be operated, improving the adjustment convenience.

[0073] In some embodiments of the present application, as Figures 5 to 7 shown, the arc-shaped guiding portion 124 is a through arc-shaped long hole. The positioning member 123 includes a bolt portion 123A and a knob portion 123B. The knob portion 123B has an internal thread that is threadedly engaged with the bolt portion 123A, and the knob portion 123B is screwed onto the bolt portion 123A by screwing.

[0074] Correspondingly, a positioning member connection hole 126 corresponding to the arc-shaped long hole is formed on the first hinge member 122, and the positioning member connection hole 126 is set to be a round hole that can allow the bolt portion 123A of the positioning member 123 to pass through.

[0075] The bolt portion 123A sequentially passes through the positioning member connection hole 126 and the arc-shaped guiding portion 124, and one end is threadedly engaged with the knob portion 123B, and the other end is formed with a stop portion 123C; the knob portion 123B abuts against the first hinge member 122, and the stop portion 123C abuts against the pitching adjusting member 121 to lock the pitching adjusting member 121.

[0076] That is, when the knob part 123B is tightened, the knob part 123B and the stop part 123C tightly sandwich the first hinge part 122 and the pitch adjustment part 121, realizing the position locking of the pitch adjustment part 121 relative to the first hinge part 122; when pitch adjustment is required, loosen the knob part 123B to have a certain clearance between the first hinge part 122 and the pitch adjustment part 121. At this time, apply force to the TV and then to the pitch adjustment part 121 to perform pitch adjustment. After the adjustment is in place, tighten the knob part 123B, which is convenient for operation.

[0077] In some embodiments of the present application, the knob part 123B is an insert molding structure, with an outer shell made of plastic material, configured in a shape that is easy to manually rotate, such as a T shape. The plastic material is relatively smooth, which can improve the operation feel; the inside of the knob part 123B is a metal cylindrical insert with internal threads, which is screwed with the metal bolt part 123A to ensure the connection reliability.

[0078] Of course, the outer shell of the knob part 123B and the metal cylindrical insert can also be fixedly connected by screws, and specific limitations are not required here.

[0079] In some embodiments of the present application, the stop part 123C is configured as a plastic part integrally molded by insert molding with the end of the metal bolt part 123A, and its width is greater than the width of the arc-shaped guide part 124, so as to be able to abut against the pitch adjustment part 121.

[0080] In some embodiments of the present application, as Figure 7 and Figure 8 shown, a positioning protrusion 123D is formed on the stop part 123C, and the positioning protrusion 123D is embedded in the arc-shaped guide part 124 to be in guiding cooperation with the arc-shaped guide part 124. The positioning protrusion 123D can fill the gap between the bolt part 123A and the arc-shaped guide part 124 to prevent the pitch adjustment part 121 from shaking and affecting the adjustment accuracy.

[0081] In some embodiments of the present application, as Figure 4 , Figure 5 and Figure 7 shown, the first hinge part 122 and the pitch adjustment part 121 are in surface contact, and their contact surface is a vertical plane to improve the fitting reliability between the first hinge part 122 and the pitch adjustment part 121 when locked; the first hinge part 122 is provided with a connecting vertical shaft 127, and the first end of the arm assembly 200 is provided with a bushing 230, and the bushing 230 is adaptively sleeved on the connecting vertical shaft 127 to realize the hinge.

[0082] In some embodiments of the present application, the first hinge member 122 includes a plastic part 122A and a metal part 122B that are integrally connected. The plastic part 122A is in surface contact with the pitching adjustment member 121, and the connecting vertical shaft 127 is provided on the metal part 122B. The metal part 122B ensures the structural strength of the first hinge member 122, and thus ensures the hinge reliability with the arm assembly 200; the pitching adjustment member 121 is a metal part, and the plastic part 122A can avoid hard contact with the pitching adjustment member 121 and reduce the adjustment noise.

[0083] The plastic part 122A and the metal part 122B of the first hinge member 122 can be integrally formed by insert molding or integrally connected by screws, and specific limitations are not required here.

[0084] Refer to Figures 9 to 11 , and at the same time in combination with Figure 3 , in some embodiments of the present application, the TV connection assembly 100 further includes a height adjustment mechanism 130 for adjusting the installation height of the TV, that is, adjusting the distance of the TV relative to the horizontal ground.

[0085] The height adjustment mechanism 130 includes a lifting member and a lifting driving member. The pitching adjustment member 121 is integrally connected to the lifting member, and the lifting driving member is in transmission connection with the lifting member to drive the lifting member to move up and down. Furthermore, the TV is driven to move up and down through the pitching adjustment member 121 and the TV connection main body 110, so as to achieve height adjustment and meet the needs of different users for different viewing heights.

[0086] In some embodiments of the present application, as Figure 3 , Figures 9 to 11 shown, the height adjustment mechanism 130 is a lead screw slider mechanism, including a lead screw 131 and a slider 132. The slider 132 is the lifting member of the height adjustment mechanism 130, and the lead screw 131 is its lifting driving member; the TV connection main body 110 further includes a vertically extending lifting guide member 115, and the slider 132 of the lead screw slider mechanism is in sliding guide fit with the lifting guide member 115.

[0087] The lifting guide member 115 is a vertically extending plate-shaped member or block-shaped member. Its top end is connected to the upper horizontal strip-shaped connecting plate 111 of the TV connection main body 110, and its bottom end is connected to the lower horizontal strip-shaped connecting plate 111 of the TV connection main body 110. A vertically extending chute 116 is formed on the lifting guide member 115, and a guide protrusion that can be embedded in the chute 116 can be formed on the slider 132 of the lead screw slider mechanism, so that the slider 132 can only slide up and down under the guide fit of the guide protrusion and the chute 116.

[0088] For the lead screw 131 of the lead screw slider mechanism, it extends vertically on the lifting and guiding component 115 and is configured to only rotate and not move up and down. For example, the top and bottom ends of the lead screw can be vertically limited by two upper and lower mounting seats 133 so that it cannot move up and down, but can rotate relative to the mounting seat 133. An internal thread hole that mates with the thread of the lead screw 131 is formed inside the slider 132. The slider 132 is sleeved on the lead screw 131, and the rotation of the lead screw 131 drives the slider 132 to slide up and down.

[0089] Regarding the connection between the slider 132 and the pitching adjustment member 121, in some embodiments of the present application, a transition connection plate 134 is fixedly connected (such as by welding or screw connection, etc.) to the slider 132, and is fixedly connected to the pitching adjustment member 121 through the transition connection plate 134 (such as by welding or screw connection, etc.). The transition connection plate 134 is configured to have a relatively large area to increase the contact area and connection reliability with the pitching adjustment member 121, thereby improving the connection reliability between the TV connection assembly 100 and the arm assembly 200.

[0090] In some embodiments of the present application, the slider 132 can be slidably and guidingly mated with the chute 116 of the lifting and guiding component 115 through the transition connection plate 134 to guide the up and down sliding of the slider 132. At this time, there is no need to form a guiding structure on the slider 132 that mates with the chute 116. The transition connection plate 134 is configured to have a vertical dimension larger than the vertical dimension of the slider 132 to increase the contact length with the chute 116, making the sliding of the slider 132 more stable, and thus making the adjustment of the TV height more stable.

[0091] To facilitate the height adjustment operation, in some embodiments of the present application, the lead screw 131 includes a lead screw body 131A and a rotation driving handle 131B. The lead screw body 131A is rotatably arranged on the lifting and guiding component 115, and the rotation driving handle 131B is axially telescopically inserted into the lead screw body 131A.
