Description

Technical Field

[0001] The utility model relates to accessories for display devices, and particularly to a structural improvement of a mounting bracket for display devices. Background Art

[0002] For wall-mounted display devices, such as televisions, a mounting bracket is required to achieve wall-mounted installation of the display device on a wall. The structure of a mounting bracket for a display device generally includes three major parts, namely a wall connection component, an arm component, and a display device connection component. The arm component is connected between the wall connection component and the device connection component. One end of the arm component is hinged to the display device connection component, and the other end is hinged to the wall connection component, so that the television can be adjusted in the front-back position and left-right position relative to the wall.

[0003] To increase the adjustment range, the arm component of the mounting bracket for a display device generally includes a first swing arm and a second swing arm. The first end of the first swing arm is hinged to the display device connection component, the second end is hinged to the first end of the second swing arm, and the second end of the second swing arm is hinged to the wall connection component.

[0004] In the related art, for the hinge connection between the first swing arm and the second swing arm of the arm component, a vertically arranged round tube is usually welded to the second end of the first swing arm, and a cylindrical rotating shaft vertically arranged is also correspondingly welded to the first end of the second swing arm. An annular stop projection is formed on the outer wall of the rotating shaft. The round tube is sleeved downward from above the rotating shaft and the bottom end abuts against the stop projection of the rotating shaft. The stop projection restricts the round tube from moving downward continuously; an upper stop member is arranged at the top end of the rotating shaft, and the upper stop member restricts the round tube from moving upward, so that the round tube is stably sleeved on the rotating shaft, and the hinge connection between the first swing arm and the second swing arm is realized through the rotational cooperation between the round tube and the rotating shaft.

[0005] For these structural forms of the arm component, the rotational damping force, that is, the rotational frictional force, between the first swing arm and the second swing arm cannot be adjusted, resulting in the situation that the hinge connection between the first swing arm and the second swing arm is too tight or too loose. If it is too tight, it is not convenient for rotational adjustment; if it is too loose, it will cause shaking.

[0006] The above information disclosed in this background art is only used to increase the understanding of the background art of this application. Therefore, it may include prior art that is not known to those of ordinary skill in the art. Summary of the Invention

[0057] Referring to Figures 1 to 3 , in some embodiments of the present application, a display device mount is provided, including a display device connection component (not shown), an arm assembly 100, and a wall connection component 200.

[0058] In some embodiments of the present application, the display device mount is a TV mount, such as a home or commercial TV.

[0059] The display device connection component faces the side where the user is located and is used to connect to the display device, specifically connected to the rear shell of the display device. The display device connection component can adopt the structure in the relevant prior art and no specific limitation is required for it.

[0060] The wall connection component 200 is close to the wall side and is used to connect to the wall.

[0061] The arm assembly 100 is extended and arranged between the display device connection component and the wall connection component 200, and is used to connect the display device connection component and the wall connection component 200, thereby mounting the display device on the wall and realizing the wall-mounted installation of the display device.

[0062] In some embodiments of the present application, as Figures 1 to 3 shown, the display device mount is a double-arm mount, that is, only one set of the arm assembly 100 is provided, including two swing arms, namely a first swing arm 110 and a second swing arm 120. The first swing arm 110 is close to the side where the display device is located, and the second swing arm 120 is close to the side where the wall is located. The first end of the first swing arm 110 is hinged to the display device connection component, the second end of the second swing arm 120 is hinged to the wall connection component 200, and the second end of the first swing arm 110 is hinged to the first end of the second swing arm 120.

[0063] Adopting a double-arm mount, the structure is simple, and the number of parts and the volume are reduced as much as possible, especially suitable for small display devices, such as the wall-mounted installation requirements of small-size TVs.

[0064] Of course, two sets of the arm assembly 100 can also be arranged left and right, with a four-arm structure, and no specific limitation is required here.

[0065] In some embodiments of the present application, with reference to Figures 4 to 9 , and in combination with Figures 1 to 3 , a vertically arranged first circular tube 111 is fixedly provided at the second end of the first swing arm 110, and a vertically arranged rotating shaft 121 is fixedly provided at the first end of the second swing arm 120. The first circular tube 111 is sleeved on the rotating shaft 121 and is rotationally matched with the rotating shaft 121, thereby realizing the hinge connection between the second end of the first swing arm 110 and the first end of the second swing arm 120.

[0066] Since the second end of the first swing arm 110 and the first end of the second swing arm 120 are located on the same axis, the first circular tube 111 is sleeved on the rotating shaft 121 from top to bottom or from bottom to top, and corresponding stop portions need to be provided on the rotating shaft 121 to limit the first circular tube 111 when it is sleeved in place. That is, when the first circular tube 111 is sleeved from top to bottom until its lower end abuts against the stop portion, the first circular tube 111 cannot be sleeved further downward; or when the first circular tube 111 is sleeved from bottom to top until its upper end abuts against the stop portion, the first circular tube 111 cannot be sleeved further upward.

[0067] For the convenience of description, the two ends of the first circular tube 111 are respectively referred to as the sleeving starting end 111A and the sleeving ending end 111B; when the first circular tube 111 is sleeved from top to bottom, its lower end is the sleeving starting end 111A, and its upper end is the sleeving ending end 111B; when the first circular tube 111 is sleeved from bottom to top, its upper end is the sleeving starting end 111A, and its lower end is the sleeving ending end 111B. That is, taking the state where the first circular tube 111 is sleeved in place as the standard, the end of the first circular tube 111 that is immediately adjacent to and above the stop portion is its sleeving starting end 111A, and the end far from the stop portion is its sleeving ending end 111B.

[0068] In some embodiments of the present application, the stop portion is a stop protrusion 121C formed on the outer wall of the rotating shaft 121 and located between the two ends of the rotating shaft 121. The stop protrusion 121C axially divides the rotating shaft 121 into upper and lower sections. One section is rotationally sleeved and matched with the first circular tube 111, and the other section is fixedly connected to the first end of the second swing arm 120. In the state where the first circular tube 111 is sleeved in place, the sleeving starting end 111A of the first circular tube 111 abuts against the stop protrusion 121C.

[0069] Similarly for the convenience of description, the two ends of the rotating shaft 121 are respectively referred to as the locking end 121A and the fixed end 121B. The locking end 121A corresponds to the sleeving ending end 111B of the first circular tube 111, that is, it is located at the same end as the sleeving ending end 111B of the first circular tube 111; correspondingly, the fixed end 121B is the other end of the rotating shaft 121.

[0070] In some embodiments of the present application, such as Figures 2 to 4As shown, a first threaded hole 121D is provided on the end face of the locking end 121A of the rotating shaft 121, and a first locking screw 130 is installed in the first threaded hole 121D. A force transmission member is provided between the first locking screw 130 and the sleeving termination end 111B of the first circular tube 111 for transmitting the tightening force of the first locking screw 130 to the sleeving termination end 111B of the first circular tube 111.

[0071] After the first circular tube 111 is sleeved in place, the sleeving termination end 111B of the first circular tube 111 is tightly connected to the locking end 121A of the rotating shaft 121 by tightening the first locking screw 130, so that the first circular tube 111 will not axially disengage from the rotating shaft 121.

[0072] By adjusting the tightening force of the first locking screw 130 to adjust the depth of its screwing into the first threaded hole 121D, the gap between the force transmission member and the first circular tube 111 is adjusted, thereby changing the pressure between the force transmission member and the first circular tube 111, and correspondingly changing the rotational damping force between the first circular tube 111 and the rotating shaft 121, that is, the rotational friction force, so that the hinged part between the first swing arm 110 and the second swing arm 120 has a function of adjusting the tightness, which is convenient for adjustment according to the actual experience requirements of users.

[0073] In some embodiments of the present application, the first circular tube 111 is sleeved on the upper section of the rotating shaft 121 from top to bottom relative to the rotating shaft 121, and the first end of the second swing arm 120 is fixedly connected to the lower section of the rotating shaft 121, as Figures 1 to 3 shown. Correspondingly, the upper end of the first circular tube 111 is the sleeving termination end 111B, the upper end of the rotating shaft 121 is its locking end 121A, and the first locking screw 130 is screwed into the first threaded hole 121D from top to bottom.

[0074] Adopting this structural form, in addition to limiting the sleeving of the first circular tube 111, the stop portion can also support the first circular tube 111, and the first locking screw 130 is screwed and tightened from top to bottom. Compared with screwing and tightening from bottom to top, the locking connection reliability of the first locking screw 130 will not be affected by the gravity of the display device.

[0075] In some embodiments of the present application, the force transmission member includes a gasket 140, and the gasket 140 is sleeved on the first locking screw 130 and is located between the head of the first locking screw 130 and the sleeving termination end 111B of the first cylinder.

[0076] In some embodiments of the present application, as Figure 2 and Figure 4As shown, the force transmission member includes a first sleeve 150, which is sleeved on the locking end 121A of the rotating shaft 121, and the first sleeve 150 is located between the rotating shaft 121 and the first round tube 111. The first sleeve 150 is formed with a force transmission portion 151 protruding outward along its radial direction, and the force transmission portion 151 is sandwiched between the gasket 140 and the end surface of the sleeve terminal end 111B of the first round tube 111. The tightening force of the first locking screw 130 is transmitted to the sleeve terminal end 111B of the first round tube 111 through the gasket 140 and the force transmission portion 151 of the first sleeve 150.

[0077] By adopting the above-mentioned structural form, the tightening force of the first locking screw 130 can be smoothly transmitted to the sleeve terminal end 111B of the first round tube 111, and due to the anti-friction and lubricating effect of the first sleeve 150, the first round tube 111 can rotate smoothly and with low noise relative to the rotating shaft 121, and the wear and damage to the first round tube 111 and the rotating shaft 121 can be reduced, thereby increasing the service life.

[0078] The first sleeve 150 can extend downward from the sleeve termination end 111B of the first round tube 111 to the sleeve start end 111A thereof, or can be shorter, extending downward from the sleeve termination end 111B of the first round tube 111 to about one third of the length of the upper section of the rotating shaft 121. Figure 4 As shown, it can also play the role of force transmission and friction reduction and lubrication, while also reducing costs.

[0079] In some embodiments of the present application, Figures 2 to 4 As shown, a second sleeve 160 is sleeved on the rotating shaft 121 , and the second sleeve 160 is located between the rotating shaft 121 and the first round tube 111 , and the second sleeve 160 is located between the stopper and the locking end 121A.

[0080] That is, the first shaft sleeve 150 and the second shaft sleeve 160 are respectively disposed at the two ends of the first circular tube 111 , and two shaft sleeves with smaller axial dimensions can be selected, which is beneficial to reducing production costs.

[0081] In some embodiments of the present application, a friction-reducing portion 161 is formed on the second sleeve 160 and protrudes radially outward. The friction-reducing portion 161 is clamped between the stop portion and the end face of the sleeve starting end 111A of the first circular tube 111, so as to avoid direct contact between the sleeve starting end 111A of the first circular tube 111 and the stop portion, thereby playing a friction-reducing and lubricating role in the rotation of the first circular tube 111 relative to the stop portion.

[0082] In some embodiments of the present application, the circumferential side wall of the first bushing 150 is provided with an inclined opening 152, and the first bushing 150 is elastic. The inclined opening 152 penetrates through both ends of the first bushing 150, and the first bushing 150 is in close contact with the rotating shaft 121. The elastic deformation of the first bushing 150 enables it to change the inner diameter size, so that it can be applicable to rotating shafts 121 of various different diameters, and is more convenient for sleeving and installation compared with bushings of fixed sizes.

[0083] In some embodiments of the present application, the circumferential side wall of the second bushing 160 is also provided with an inclined opening (not marked) and is elastic. The inclined opening penetrates through both ends of the second bushing 160, and the second bushing 160 is in close contact with the rotating shaft 121. The elastic deformation of the second bushing 160 enables it to change the inner diameter size, so that it can be applicable to rotating shafts 121 of various different diameters, and is more convenient for sleeving and installation compared with bushings of fixed sizes.

[0084] In some embodiments of the present application, the first bushing 150 and the second bushing 160 are integrally formed plastic bushings respectively. The force transmission part 151 is an annular flange formed on the edge of one end of the first bushing 150, and the friction reduction part 161 is an annular flange formed on the edge of one end of the second bushing 160. The plastic bushing is softer than the sheet metal part, which will not hinder the relative rotation between the two rotating mating parts and can reduce the radial clearance between the two rotating mating parts.

[0085] For the wall connection assembly 200, in some embodiments of the present application, as Figure 1 、 Figure 2 、 Figure 5 、 Figure 10 and Figure 11 shown, it includes a second locking screw 210. The second locking screw 210 is vertically arranged and only the tail 212 has threads, and its rod part 211 is a smooth rod.

[0086] In some embodiments of the present application, the wall connection assembly 200 further includes a wall connection member 220. A wall connection part 221 for connecting with the wall and a swing arm connection part 222 connected to the second end of the second swing arm 120 are provided on the wall connection plate.

[0087] The wall connection part 221 is specifically a fixing hole, which is approximately located at the center position in the width direction of the wall connection member 220 and includes an upper fixing hole and a lower fixing hole. The upper fixing hole is located at the upper part of the wall connection member 220, and the lower fixing hole is located at the lower part of the wall connection member 220. The wall connection member 220 is installed and fixed on the wall through corresponding long screws.

[0088] Among the upper fixing hole and the lower fixing hole, one of them can be a round hole and the other can be a horizontal long hole to facilitate positioning and installation.

[0089] There are two swing arm connection parts 222 arranged vertically one above the other. An installation hole 222A is provided on one of the swing arm connection parts 222, and a second threaded hole 222B is provided on the other swing arm connection part 222. The second locking screw 210 passes through the installation hole 222A and is threadedly connected to the second threaded hole 222B.

[0090] A vertical second circular tube 122 is fixedly provided at the second end of the second swing arm 120. The second circular tube 122 is sleeved on the rod portion 211 of the second locking screw 210 and is rotationally matched with the rod portion 211 to realize the hinge connection between the second end of the second swing arm 120 and the wall connection member 220; the two swing arm connection parts 222 are respectively in contact with the upper and lower end faces of the second circular tube 122 to transmit the tightening force of the second locking screw 210 to the second circular tube 122.

[0091] By adjusting the tightening force of the second locking screw 210 to adjust the depth of its screwing into the second threaded hole 222B, and further adjusting the gap between the contact surfaces of the swing arm connection part 222 and the second circular tube 122, thereby changing the pressure between the swing arm connection part 222 and the second circular tube 122, and correspondingly changing the rotational damping force, that is, the rotational friction force, between the second circular tube 122 and the rod portion 211 of the second locking screw 210, so that the hinge part between the second swing arm 120 and the wall connection assembly 200 has a function of adjusting the tightness, which is convenient for adjustment according to the actual experience requirements of users.

[0092] During installation, first insert the second circular tube 122 between the two swing arm connection parts 222, then insert and install the second locking screw 210 vertically, and finally tighten the second locking screw 210 with an appropriate force.

[0093] In some embodiments of the present application, the upper swing arm connection part 222 is provided with the installation hole 222A, the lower swing arm connection part 222 is provided with the second threaded hole 222B, and the second locking screw 210 is inserted from top to bottom relative to the second circular tube 122.

[0094] In some embodiments of the present application, a third shaft sleeve 170 is provided between the second circular tube 122 and the rod portion 211 of the second locking screw 210. A protruding portion 171 protruding radially outward is formed on the third shaft sleeve 170, and the protruding portion 171 is clamped between the swing arm connection part 222 and the end face of the second circular tube 122.

[0095] The friction-reducing and lubricating effect of the third sleeve 170 allows the second round tube 122 to rotate smoothly and with little noise relative to the second locking screw 210 , and reduces wear and damage to the second round tube 122 and the second locking screw 210 , thereby increasing service life.

[0096] To facilitate installation and reduce production costs as much as possible, the third sleeve 170 is two separate small-sized sleeves, which are respectively installed on the upper end and the lower end of the second round tube 122.

[0097] In some embodiments of the present application, in order to enhance the structural strength and load-bearing capacity of the wall connection assembly 200 and thereby improve the reliability of the entire display device bracket, each swing arm connection portion 222 includes a horizontal flange portion 222C formed on the wall connection member 220 and a bracket 222D welded on the wall connection member 220, and the bracket 222D and the horizontal flange portion 222C are arranged up and down and fit against each other.

[0098] The wall connecting member 220 is specifically a sheet metal part, and the horizontal flange portion 222C is formed by stamping and bending. The bracket 222D and the horizontal flange portion 222C can support and reinforce each other, thereby improving the load-bearing capacity of the wall connecting component 200 and the entire display device rack.

[0099] In some embodiments of the present application, a first welding positioning hole 223 is formed on the wall connector 220, and a first welding positioning protrusion 222E is correspondingly formed on the bracket 222D. The first welding positioning protrusion 222E is embedded in the first welding positioning hole 223 for positioning, which facilitates welding and helps to improve welding reliability. Specifically, laser welding can be used for welding.

[0100] In order to improve the structural strength and load-bearing capacity of the display device rack in the embodiment of the present application, in some embodiments of the present application, reference is made to Figures 6 to 9 A first arc-shaped welding portion 112 is formed on the second end of the first swing arm 110 . The first arc-shaped welding portion 112 is welded to the first circular tube 111 and surrounds a section of the first circular tube 111 , that is, the first circular tube 111 is clamped inside by the first arc-shaped welding portion 112 .

[0101] The second arc-shaped welding portion 123 is respectively formed on the first end and the second end of the second swing arm 120. The second arc-shaped welding portion 123 on the first end is welded to the rotating shaft 121 and surrounds a section of the rotating shaft 121, that is, the rotating shaft 121 is clamped inside by the second arc-shaped welding portion 123; the second arc-shaped welding portion 123 on the second end is welded to the second circular tube 122 and surrounds the second circular tube 122, that is, the second circular tube 122 is clamped inside by the second arc-shaped welding portion 123.

[0102] Taking the example that the first circular tube 111 is sleeved on the rotating shaft 121 from above the rotating shaft 121, at this time, the first arc-shaped welding part 112 of the first swing arm 110 wraps the upper section of the first circular tube 111, and the lower section of the first circular tube 111 is exposed downward. The second arc-shaped welding part 123 at the first end of the second swing arm 120 wraps the lower section of the rotating shaft 121, so that the lower section of the first circular tube 111 and the upper section of the rotating shaft 121 are sleeved and rotationally matched.

[0103] The first arc-shaped welding part 112 wraps the upper section of the first circular tube 111, and the contact area between the two is large, and the welding contact area is large. At the same time, the second arc-shaped welding part 123 at the first end of the second swing arm 120 wraps the lower section of the rotating shaft 121, and the contact area between the two is large, and the welding connection area is large. Moreover, the second arc-shaped welding part 123 at the second end of the second swing arm 120 wraps the second circular tube 122, and the contact area between the two is large, and the welding connection area is large.

[0104] Through the above structure, the integrity and structural strength of the entire arm assembly 100 can be effectively improved, and further improve the overall structural strength of the display device hanger and the reliability of the wall-mounted installation of the display device.

[0105] The welding part can adopt laser welding to form an enclosed laser weld seam, with a large welding contact area and excellent stress performance.

[0106] Since the square tube used for the swing arm in the related art is a standard part, when manufacturing the swing arm, it is necessary to select from the existing standard part size structures of the square tube, which has certain limitations and cannot achieve the optimal cost under the premise of ensuring the most optimized structure.

[0107] To solve this problem, in some embodiments of the present application, as Figures 6 to 9 shown, both the first swing arm 110 and the second swing arm 120 are split structures, and the split structure principles of the two are the same. Here, only the first swing arm 110 is taken as an example for illustration.

[0108] The first swing arm 110 includes a first swing arm part 113 and a second swing arm part 114. The first swing arm part 113 and the second swing arm part 114 are arranged oppositely and are welded together to form the overall first swing arm 110. Then, the first swing arm 110 can not adopt the existing square tube standard parts. For example, it can be formed by sheet metal stamping or machining, etc., so that the swing arm can be changed from outsourcing to independent production, with controllable production capacity. The size of the swing arm can be unrestricted by the existing standardized square tube, and the key parameters such as its length, width, height, and wall thickness can be independently designed and adjusted to save costs while ensuring performance with the most optimized structure.

[0109] The first swing arm part 113 and the second swing arm part 114 are symmetrically arranged with each other to further facilitate processing and forming.

[0110] The first part 113 of the swing arm and the second part 114 of the swing arm can both be formed by sheet metal stamping, which is convenient for processing and has high structural strength; at the same time, after the first part 113 of the swing arm and the second part 114 of the swing arm of the above structure are welded and connected, a hollow structure like a square tube can be formed inside to reduce the weight of the swing arm as much as possible.

[0111] Regarding the connection between the first end of the first swing arm 110 and the display device connection assembly, in some embodiments of the present application, such as Figures 1 to 3 , Figure 6 and Figure 7 As shown, a U-shaped frame 180 with an opening toward the display device is welded to the first end of the first swing arm 110 , and a reinforcing structure 181 and a connecting structure for connecting to a display device connecting assembly are formed on the U-shaped frame 180 .

[0112] The U-shaped frame 180 can be made of sheet metal, and the reinforcement structure 181 is a reinforcement rib formed thereon, such as a convex rib, etc., to improve the force-bearing performance; the connection structure connected to the display device connection component can be a connection hole 182, so as to be hinged with the hinge axis on the display device connection component.

[0113] In some embodiments of the present application, a second welding positioning hole 183 is formed on the U-shaped frame 180, and a second welding positioning protrusion 115 is correspondingly formed on the first end of the first swing arm 110. The second welding positioning protrusion 115 is embedded in the second welding positioning hole 183 for positioning to facilitate welding; the first end face of the first swing arm 110 is adapted to fit the U-shaped frame 180 for laser welding connection to increase the welding contact area and improve the reliability of the welding connection.

[0114] In the description of the above embodiments, specific features, structures, materials or characteristics may be combined in a suitable manner in any one or more embodiments or examples.

[0115] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited to this. Any changes or substitutions that can be easily thought of by technicians familiar with the technical field within the technical scope disclosed by the utility model should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
