Description

TECHNICAL FIELD

[0001] The present application relates to the field of television wall mounting brackets, and particularly relates to a multi-degree-of-freedom adjustable network television wall mounting bracket mechanism. BACKGROUND

[0002] As a kind of installation accessory that fixes television on wall, saves space and optimizes viewing experience, television wall mounting bracket has been widely used in various scenes such as home, office and commercial display. It is mainly used to transfer the support structure of television from the traditional ground or desktop to the vertical wall, and realize stable suspension through specific mechanical connection mode. According to the complexity of function, television bracket can be divided into two categories: fixed type and adjustable type. Among them, the adjustable type bracket itself can realize multi-dimensional position and angle adjustment of television in front and back extension, left and right rotation, pitch inclination, etc. to meet the individual needs of users in different viewing positions and angles, and has become the mainstream in the market.

[0003] The degree-of-freedom bracket usually includes three core components: a wall plate mounting bracket fixed on the wall, a television mounting bracket for connecting the television, and a multi-joint mechanical arm (or folding arm) connecting the two. The mechanical arm realizes joint movement through multiple rotating shafts, thereby driving the television to displace in space. When the user needs to pull the viewing distance or adjust the angle, the television can be pulled out and rotated to move away from the initial position close to the wall.

[0004] However, there are still the following defects and deficiencies in the implementation and application process: When the television (with a certain weight) is extended to a position away from the wall through the mechanical arm, an overturning moment will be formed, with the wall fixed point as the fulcrum and the horizontal distance from the center of gravity of the television to the fulcrum as the force arm. The moment will continuously act on the wall plate mounting bracket and its fixed point. The traditional fixed mode relies on several expansion bolts passing through the wall plate mounting bracket and penetrating into the wall. These bolts, especially the upper bolts, mainly bear the shear force (or pullout force) perpendicular to the wall converted from the above overturning moment. With the increase of the extension distance of the television, the shear force borne by the bolts increases sharply. This not only requires high material strength of the wall (such as whether it is a solid wall), but also the combination surface between the bolt and the wall hole wall is prone to stress concentration and fatigue loosening under long-term alternating load or instantaneous impact, increasing the risk of fixation failure.

[0005] Therefore, it is necessary to provide a new multi-degree-of-freedom adjustable network television wall mounting bracket mechanism to solve the above technical problems. SUMMARY

For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0023] In order to make the purpose, technical scheme and advantages of the present application more clear and explicit, the present application will be further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the present application, and are not used to limit the present application.

[0024] The specific implementation of the present application is described in detail below in combination with specific examples.

[0025] Please refer to Figures 1 to 6The multi-degree-of-freedom adjustable network television wall-mounted support mechanism provided by the embodiment of the present application comprises a wallboard mounting frame 1 and a television mounting frame 5, which are connected through a folding arm 4 to form a conventional television mounting support structure. The television mounting frame 5 can be adjusted in the horizontal direction, i.e., the folding arm 4 is symmetrically arranged in two groups, which comprises a rotating arm 1 and a rotating arm 2 connected with the rotating arm 1. The other end of the rotating arm 1 is connected with the wallboard mounting frame 1 through a shaft 1, and the other end of the rotating arm 2 is connected with the television mounting frame 5 through a shaft 2. Therefore, the rotating arm 1 can rotate relative to the wallboard mounting frame 1, the rotating arm 2 can rotate relative to the rotating arm 1, and the television mounting frame 5 can rotate relative to the rotating arm 2. Therefore, the television mounting frame 5 and the television mounted thereon have displacement floating adjustment towards the front and back and the two sides, and angle floating adjustment in the horizontal direction, and the adjustment is very convenient.

[0026] The position of the television itself is adjusted vertically. The television mounting frame 5 has two vertical vertical beams, the vertical beams have through holes distributed along the length direction, and the television back plate has mounting holes corresponding to the through holes. After the mounting holes correspond to the through holes at different heights and are fixed by bolts, the height of the television itself can be adjusted.

[0027] To further increase the stability of the wallboard mounting frame 1 on the wall, a sub mounting frame 6 capable of being assembled with the wallboard mounting frame 1 is further arranged. That is, the wallboard mounting frame 1 has a groove 2 penetrating the upper and lower ends on the side close to the wall surface, and the sub mounting frame 6 can be embedded in the groove 2 to improve the assembly compactness between the wallboard mounting frame 1 and the sub mounting frame 6. The height of the sub mounting frame 6 is greater than that of the wallboard mounting frame 1, and the upper and lower ends of the sub mounting frame 6 exceed the upper and lower ends of the wallboard mounting frame 1.

[0028] A clamping type limiting structure is further arranged between the top of the wallboard mounting frame 1 and the sub mounting frame 6. The clamping type limiting structure comprises a plurality of tooth plates 3 integrally connected to the upper end of the wallboard mounting frame 1, and a positioning plate one 7 vertically welded to one side of the sub mounting frame 6 and having a tooth groove 8, and the tooth plates 3 can be stably clamped with the tooth groove 8. The tooth plates 3 are arranged along the length direction of the wallboard mounting frame 1, and the cross sections of the tooth plates 3 and the tooth groove 8 are both arranged in a right trapezoidal shape to enhance the connection stability of the two. Therefore, the positioning plate one 7 can generate a pulling force towards the wall surface direction on the wallboard mounting frame 1 to further improve the bearing capacity of the wallboard mounting frame 1.

[0029] The sub mounting frame 6 is also fixed on the wall by bolts, and is not connected with the wallboard mounting frame 1 by a steel structure, so that the sub mounting frame 6 itself also has strong compression resistance.

[0030] The auxiliary wallboard mounting frame 1 is also provided with an elastic support structure for positioning and assembling the auxiliary wallboard mounting frame 1. The elastic support structure comprises a positioning plate two 9 vertically welded on one side of the auxiliary mounting frame 6, the positioning plate two 9 is provided with a plurality of light holes, each light hole is slidably connected with a vertically arranged slide rod 10, the upper end of the slide rod 10 is fixedly connected with a top plate 11, a spring 12 is further sleeved on the slide rod 10, one end of the spring 12 acts on the positioning plate two 9, and the other end acts on the top plate 11, so as to generate an upward elastic force on the top plate 11. The positioning plate two 9 is located below the positioning plate one 7, and a clamping groove is formed between the two for embedding the upper plate piece of the wallboard mounting frame 1 (the wallboard mounting frame 1 is in the shape of a mouth, and is composed of upper, lower, left and right four plate pieces). After the upper plate piece of the wallboard mounting frame 1 is placed in the clamping groove, the positioning plate two 9 can generate an elastic force on it to push the wallboard mounting frame 1 upward. Until the tooth plate 3 at the upper end of the wallboard mounting frame 1 is embedded in the tooth groove 8 on the positioning plate one 7. At this time, the wallboard mounting frame 1 can be kept stable, which is more convenient for subsequent bolt fixing of the wallboard mounting frame 1, and can also improve the assembly compactness between the tooth plate 3 and the tooth groove 8.

[0031] The auxiliary mounting frame 6 is provided with a foot plate 13 integrally connected at the lower end, and the foot plate 13 is horizontally arranged. A support assembly is further arranged between the foot plate 13 and the rotating arm one. The support assembly comprises a columnar connecting cylinder 14, the connecting cylinder 14 is provided with an axial assembly cavity at both ends, a threaded rod 15 is threadedly connected in one of the assembly cavities, and a light rod 16 is rotatably connected in the other assembly cavity. The threaded rod 15 and the light rod 16 are both provided with an external end head outside the assembly cavity, and an integral ring seat 17 is arranged on the external end head. The ring seat 17 is rotatably connected with a connecting seat 18 through a pin shaft. That is, the connecting cylinder 14, the threaded rod 15 and the light rod 16 jointly form a telescopic support member. By rotating the connecting cylinder 14, the extension length of the threaded rod 15 can be adjusted. Therefore, during subsequent installation, the installation precision can be further improved, so that the support member can stably support the rotating arm two.

[0032] The connecting seat 18 arranged at the end of the threaded rod 15 is rotatably connected to the foot plate 13 through a shaft three, and the axis of the shaft three coincides with the axis of the shaft one. Therefore, when the rotating arm one rotates, the entire support member will rotate synchronously, ensuring that the support member can always stably support the rotating arm one at any position.

[0033] The connecting seat 18 arranged at the end of the light rod 16 is rotatably connected to the rotating arm one through a shaft four, so that the support member can support the rotating arm one, and further support the entire folding arm 4, i.e. the television mounting frame 5.

[0034] The specific use mode of the device is as follows: First step: First, the vice mounting frame 6 is directly fixed to the wall at the predetermined position by the bolts provided thereon. During installation, ensure that it is vertical and that the positioning plate one 7 at the upper end and the positioning plate two 9 at the lower end are outward. The horizontal foot plate 13 at the lower part of the vice mounting frame 6 should be kept horizontal. After completion of the fixing, the elastic support structure (including the slide rod 10, the top plate 11 and the spring 12) on the positioning plate two 9 is in the initial state, and the position of the top plate 11 is closer to the position of the positioning plate one 7, but there is a certain interval between the two, which is the clamping groove for installing the wall plate mounting frame 1.

[0035] Second step: The recess 2 at the back of the wall plate mounting frame 1 is aligned and embedded in the fixed vice mounting frame 6. The upper plate of the wall plate mounting frame 1 is placed in the clamping groove formed by the positioning plate one 7 and the positioning plate two 9, and the lower edge thereof is pressed on the top plate 11. The wall plate mounting frame 1 is pressed downward to compress the spring 12, and then it is pushed upward, so that the upward elastic force provided by the elastic support structure makes the multiple tooth plates 3 at the upper end of the wall plate mounting frame 1 accurately embedded in the tooth groove 8 of the positioning plate one 7, and the engagement and locking are completed. After confirmation of stability, the wall plate mounting frame 1 is finally fastened to the wall by bolts through the mounting holes thereof.

[0036] Third step: The rotating arm one of the two symmetrical folding arms 4 is rotatably connected to the wall plate mounting frame 1 through the shaft one. Then, the connecting seat 18 at one end of the threaded rod 15 of the support assembly is rotatably connected to the foot plate 13 of the vice mounting frame 6 through the shaft three, and it is ensured that the shaft three is coaxial with the shaft one. Subsequently, the connecting seat 18 at one end of the light rod 16 of the support assembly is rotatably connected to the rotating arm one through the shaft four. The rotating connection cylinder 14 is rotated to adjust the overall length of the support member, so that it stably supports the rotating arm one. Finally, the rotating arm two of the folding arm 4 is rotatably connected to the television mounting frame 5 through the shaft two.

[0037] Fourth step: The two vertical beams at the back of the television mounting frame 5 are aligned with the mounting holes of the back plate of the television set, the initial hanging height of the television set is adjusted by selecting different height through holes, and it is preliminarily fixed by bolts. Subsequently, the assembled television mounting frame 5 and the television set are lifted as a whole, so that the television mounting frame 5 is finally connected to the rotating arm two of the folding arm 4 through the shaft two. It is checked whether all the rotatable connections are smooth, and finally all the bolts between the television set and the television mounting frame 5 are fastened, and the entire installation process is completed.

[0038] The circuit and control involved in the present application are prior art, and will not be described in detail here.

[0039] The above is only an embodiment of the present application, and does not limit the patent range of the present application. Any equivalent structure or equivalent process transformation using the content of the specification and drawings, or direct or indirect application in other related technical fields is also included in the patent protection range of the present application.
