Description

Technical Field

[0001] The invention relates to the technical field of television hangers, and in particular to a hanging arm assembly. Background Art

[0002] TV mounts generally fall into three categories: fixed mounts, angle-adjustable mounts, and mounts with telescopic swing arms. Among them, the fixed bracket is the simplest bracket, which has no angle adjustment function and has many disadvantages in use, such as inconvenient wiring due to the close distance to the wall and difficulty in angle adjustment; the adjustable angle bracket adds the function of adjusting the pitch angle of the TV on the basis of the fixed bracket. Since the adjustable angle bracket is also close to the wall, it is inconvenient to wire the back of the TV, and when a large-size TV is installed and the pitch angle is adjusted, the edge of the TV will hit the wall first, thereby affecting the angle range of adjusting the pitch angle, and the range of the adjustable angle bracket from the wall generally cannot be designed too large, mainly having the disadvantages of occupying space, being unsightly, and having high costs; although the bracket with a telescopic swing arm solves the above-mentioned shortcomings of the fixed bracket and the adjustable angle bracket being close to the wall, inconvenient wiring, and having a small pitch angle, the bracket with a telescopic swing arm has the disadvantages of complex structure, high cost, and high requirements for the wall to be installed. Therefore, the entire market is still dominated by fixed brackets and adjustable angle brackets, and the bracket with a telescopic swing arm has a very small market share compared to the former two.

DETAILED DESCRIPTION

[0029] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0030] like Figures 1 to 10 As shown, an embodiment of the present invention provides a hanging arm assembly. The hanging arm assembly includes: a mounting mechanism 10; a hanging arm 21, located at one side of the mounting mechanism 10, a locking portion 22 is provided on the hanging arm 21, and the hanging arm 21 is movably arranged relative to the mounting mechanism 10 so that the hanging arm 21 can approach or move away from the mounting mechanism 10; a locking mechanism 30, including a pressing member 31 and a locking member 32 arranged in linkage with the pressing member 31, the locking member 32 is movably arranged on the mounting mechanism 10, and the locking member 32 has a locking position that can be locked with the locking portion 22 and an unlocking position that is released from the locking portion 22, the pressing member 31 is movably arranged on the mounting mechanism 10, the hanging arm 21 approaches the mounting mechanism 10 and presses the pressing member 31, and the pressing member 31 drives the locking member 32 to switch between the locking position and the unlocking position.

[0031] In the above technical solution, when the locking member 32 and the locking portion 22 are in the locked position of the lock cooperation, it can ensure that the hanging arm 21 is stably fixed in the current position to support the display. The user pushes the hanging arm 21 in the direction of the mounting mechanism 10. The movement of the hanging arm 21 will contact the pressing member 31 and apply pressure to make the pressing member 31 move on the mounting mechanism 10. The movement of the pressing member 31 will drive the locking member 32 arranged in linkage with it to move from the locked position to the unlocked position, releasing the cooperation between the locking member 32 and the locking portion 22 on the hanging arm 21, so that the hanging arm 21 can freely move away from the mounting mechanism The mechanism 10 is used to increase the distance from the wall. At this time, the locking member 32 is in the unlocked position, and the arm 21 is not subject to any locking restrictions, so that it is convenient to carry out wiring and adjust the pitch angle of the arm 21 in a wide range. When the arm 21 needs to be moved back from a position away from the wall to a position close to the wall, the user pushes the arm 21 toward the mounting mechanism 10 again, and the movement of the arm 21 will contact the pressing member 31 and apply pressure to move the pressing member 31 on the mounting mechanism 10, thereby driving the locking member 32 to move from the unlocked position back to the locked position and re-lock with the locking portion 22 on the arm 21. In this way, the user only needs to push or pull the arm 21, without additionally operating the locking or unlocking mechanism, to achieve rapid adjustment of the distance between the arm 21 and the wall, so that the arm 21 can be close to the wall and support the display, and can be away from the wall to facilitate wiring operations and adjust the pitch angle of the display on the arm 21 in a wide range. The above structure is simple and can reduce production costs. In summary, the arm assembly of the embodiment of the present invention solves the problems of inconvenient rack wiring, limited angle adjustment range, high cost and complex structure in the prior art.

[0032] Furthermore, the arm assembly of the embodiment of the present invention can realize the free movement and locking of the arm 21 without the need for additional operation of the locking mechanism 30, realize flexible wiring and increase the angle adjustment range, improve operational convenience, and ensure the stability and safety of the display device.

[0033] Preferably, in the embodiment of the present invention, the locking member 32 is a fixed shaft.

[0034] like Figure 2 and Figure 4 As shown, in an embodiment of the present invention, the locking mechanism 30 also includes: an elastic member 33, one end of the elastic member 33 is connected to the locking member 32, and the other end of the elastic member 33 is connected to the mounting mechanism 10, so as to provide an elastic force for the locking member 32 to switch from a locked position to an unlocked position.

[0035] In the above technical solution, the locking member 32 is in the unlocked position, and the hanging arm 21 is away from the mounting mechanism 10, which is convenient for wiring and adjusting the display angle. At this time, the elastic member 33 is in a naturally relaxed state and does not apply additional force; when the user pushes the hanging arm 21 toward the mounting mechanism 10 to reduce the distance from the wall, the hanging arm 21 will contact and apply pressure to the pressing member 31, and the pressing member 31 moves due to the force, and drives the locking member 32 linked thereto to move from the unlocked position to the locked position, thereby fixing the position of the hanging arm 21 and ensuring stable support of the display. In this process, the elastic member 33 is stretched and the elastic force is stored to prepare for subsequent automatic unlocking; when the user needs the hanging arm 21 to return to a position away from the wall, the hanging arm 21 is pushed toward the mounting mechanism 10 again, and the hanging arm 21 contacts the pressing member 31 and applies pressure to make it move. At this time, the elastic force of the elastic member 33 begins to act, prompting the locking member 32 to return from the locked position to the unlocked position. In this way, the user only needs to simply push or pull the hanging arm 21, without the need to additionally operate the locking or unlocking mechanism, to achieve quick adjustment of the distance from the wall and automatic locking. The use of the elastic member 33 simplifies the locking mechanism and reduces production costs, while ensuring the simplicity of the structure of the hanging arm assembly and improving its adaptability to wall installation.

[0036] Preferably, in the embodiment of the present invention, the elastic member 33 is a spring.

[0037] Specifically, in the embodiment of the present invention, when the distance between the hanging arm 21 and the mounting mechanism 10 increases, under the action of the spring, the pressing member 31 moves in the same direction as the hanging arm 21 .

[0038] like Figure 6 , Figure 7 and Fig. 9 As shown, in the embodiment of the present invention, the locking mechanism 30 also includes: a pushing member 34, which is movably arranged on the mounting mechanism 10; a rotor member 35, which is rotatably arranged on the mounting mechanism 10, one end of the pushing member 34 is connected to the locking member 32, and the other end of the pushing member 34 acts on the rotor member 35, the pushing member 34 pushes the rotor member 35 to rotate to a limited state, the rotor member 35 can cooperate with the pushing member 34 in a limited manner to keep the locking member 32 in the locked position, the pushing member 34 pushes the rotor member 35 to rotate to a non-limited state again, the rotor member 35 releases the limited cooperation with the pushing member 34, and under the action of the elastic member 33, the locking member 32 can switch from the locked position to the unlocked position.

[0039] In the above technical solution, when the pushing member 34 pushes the rotor member 35 to the limited position, the rotor member 35 and the pushing member 34 are limited to form a mechanical interlock, so that the locking member 32 is maintained in the locked position, thereby firmly supporting the display on the hanging arm 21; and when unlocking is required, the pushing member 34 pushes the rotor member 35 to the non-limited position again, the rotor member 35 and the pushing member 34 are released from the limited position, and the elastic member 33 (such as a return spring) plays a role, so that the locking member 32 is switched from the locked position to the unlocked position, and the free movement of the hanging arm 21 can be achieved, thereby improving the flexibility of wiring and angle adjustment. In this way, the movement of the hanging arm 21 directly triggers the pushing member 34, and then the pushing member 34 acts on the rotor member 35 to automatically complete locking and unlocking. The user only needs to push or pull the hanging arm 21, without additionally operating the locking or unlocking mechanism, to achieve rapid adjustment of the distance between the hanging arm 21 and the wall, thereby simplifying the user's operating steps to improve the user experience.

[0040] Furthermore, the mechanical linkage design of the push member 34 and the rotor member 35 not only simplifies the operation, but also improves the safety and reliability of the arm assembly. When the arm 21 is in the locked position, the rotor member 35 and the push member 34 form a limited fit, and even under external vibration or impact, the locking member 32 is not prone to mislocking, ensuring the stable support of the display. In the unlocked state, the elastic member 33 ensures the smooth reset of the locking member 32, avoiding the instability and safety problems that may be caused by manual operation.

[0041] It should be noted that compared with the traditional manually operated locking mechanism, the automatic locking and unlocking mechanism of the embodiment of the present invention reduces unnecessary parts, reduces assembly difficulty and production costs, and also reduces strict requirements for wall installation, thereby achieving the dual goals of cost control and structural optimization.

[0042] like Figure 7 and Fig. 9 As shown, in the embodiment of the present invention, the rotor component 35 has two convex parts arranged opposite to each other, and the pushing component 34 includes: a push rod 341, which is movably arranged on the mounting mechanism 10, and the push rod 341 is connected to the locking component 32; a pushing member 342, which is connected to the push rod 341; a limiting member 343, which is connected to the push rod 341, and the pushing member 342 and the limiting member 343 are respectively arranged corresponding to the two convex parts, and the rotor component 35 is switched between the non-limiting state and the limiting state by pushing the first convex part of the two convex parts by the pushing member 342; wherein, when the rotor component 35 is in the limiting state, the limiting member 343 can be limitedly matched with the second convex part of the two convex parts, and when the rotor component 35 is switched from the limiting state to the non-limiting state, under the action of the elastic member 33, the limiting member 343 pushes the second convex part of the two convex parts to drive the rotor component 35 to rotate.

[0043] In the above technical solution, when the hanging arm 21 needs to be locked, the hanging arm 21 is pushed, and the pushing member 342 pushes the first protrusion to make the rotor component 35 rotate to the limited state, the elastic member 33 pulls the push rod 341, the limiting member 343 forms a limiting cooperation with the second protrusion, and the locking member 32 is in the locked position to lock the hanging arm 21 on the mounting mechanism 10, thereby ensuring the stability of the hanging arm 21; when the hanging arm 21 needs to adjust the distance from the wall, the pushing member 342 pushes the first protrusion again to drive the rotor component 35 to rotate from the limited state to the non-limited state, the elastic member 33 pulls the push rod 341, and the locking member 32 switches from the locked position to the unlocked position, and the hanging arm 21 can move freely at this time. In this way, through the interactive design of the two protrusions of the rotor component 35 and the pushing member 342 and the limiting member 343 of the pushing member 34, the automatic unlocking and locking of the hanging arm 21 is realized, without manual unlocking or locking, which can improve the convenience and efficiency of operation.

[0044] Furthermore, even after adjusting the distance from the wall, the locking and unlocking mechanism of the arm assembly will not affect the angle adjustment function. The user can maintain or expand the pitch angle adjustment range of the monitor, thereby solving the problem of limited angle adjustment of large-screen TVs on fixed brackets and making the angle adjustment more free.

[0045] Preferably, in the embodiment of the present invention, the rotor component 35 is prismatic or spindle-shaped.

[0046] like Figure 6 , Figure 8 and Fig. 9 As shown, in an embodiment of the present invention, the locking mechanism 30 also includes a linkage member 36, which is rotatably connected to the mounting mechanism 10, one end of the linkage member 36 is rotatably connected to the locking member 32 and one end of the linkage member 36 is slidably connected to the locking member 32, and the other end of the linkage member 36 is rotatably connected to the pressing member 31 and the other end of the linkage member 36 is slidably connected to the pressing member 31.

[0047] In the above technical solution, by setting the linkage member 36, the pressing member 31 can be Fig. 9 The horizontal movement in the middle is converted into the vertical movement of the pushing member 34, so that the movement of the hanging arm 21 can directly and smoothly drive the unlocking and locking state switching of the locking member 32, which can ensure the smooth operation of the hanging arm assembly during frequent use, reduce mechanical wear, and extend the service life of the hanging arm assembly. The user only needs to simply push or pull the hanging arm 21, without the need for additional operation of the locking mechanism, which greatly improves the convenience of operation and user experience.

[0048] like Figure 8 and Fig. 9As shown, in the embodiment of the present invention, the moving direction of the locking member 32 and the moving direction of the pressing member 31 are arranged at an angle, and the pivot point between the linkage member 36 and the mounting mechanism 10 is located between the two ends of the linkage member 36 .

[0049] Through the above arrangement, the structure of the entire locking mechanism 30 is made more compact, which can save space in the moving direction of the pressing member 31, thereby reducing the overall occupied space of the hanging arm assembly, and is particularly suitable for the narrow space between the wall and the hanging arm assembly.

[0050] In one embodiment, the moving direction of the locking member 32 and the moving direction of the pressing member 31 may be the same, so that the linkage member 36 may not be provided.

[0051] Preferably, in the embodiment of the present invention, the linkage member 36 includes two connecting plates that are connected and arranged at an angle, and the position where the two connecting plates are connected is pivotally connected to the mounting mechanism 10 .

[0052] Specifically, in the embodiment of the present invention, the locking mechanism 30 further includes a rear shell 43 , a front shell 44 , and a plurality of fasteners 18 for connecting the rear shell 43 and the front shell 44 .

[0053] like Figure 7 As shown, a hole is provided on the rear shell 43, a hole is provided on the front shell 44, and a protrusion structure is provided on each side of the rotor component 35. The two protrusion structures respectively cooperate with the holes on the front shell 44 and the rear shell 43, so that the rotor component 35 can have and only have one degree of freedom of rotation between the rear shell 43 and the front shell 44.

[0054] like Figure 7 As shown, a groove is provided on the rear shell 43, a groove is provided on the front shell 44, and a protrusion structure is provided on both sides of the push rod 341. The protrusions on both sides of the push rod 341 respectively cooperate with the grooves on the front shell 44 and the rear shell 43, so that the push rod can slide freely along the groove in the space between the front shell 44 and the rear shell 43.

[0055] like Figure 6As shown, in the embodiment of the present invention, a hole is provided on the pressing member 31, a long strip hole 37 is provided on the linkage member 36, and a fastener 18 passes through the aforementioned hole and the long strip hole 37 at the same time, so that the fastener 18 on the pressing member 31 can slide in the long strip hole 37 on the linkage member 36; another long strip hole 37 is provided on the linkage member 36, a hole is provided on the push rod 341, and the fixed shaft passes through the aforementioned long strip hole 37 and the hole at the same time, so that the fixed shaft on the push rod 341 can slide along the long strip hole 37 on the linkage member 36; another hole is provided on the linkage member 36, a hole is provided on the angle adjustment plate, and a fastener 18 passes through the two aforementioned holes at the same time, so that the linkage member 36 rotates with the hole on the angle adjustment plate as the rotation center, so as to realize the pivot connection between the linkage member 36 and the mounting mechanism 10.

[0056] like Figure 5 and Figure 6 As shown, in an embodiment of the present invention, a first guide portion 38 is provided on one of the pressing member 31 and the mounting mechanism 10, and a sliding member 39 is provided on the other of the pressing member 31 and the mounting mechanism 10. The sliding member 39 is slidably arranged on the first guide portion 38 to limit the moving direction of the pressing member 31.

[0057] Through the above-mentioned arrangement, it can be ensured that the moving direction of the pressing member 31 is precisely controlled, and the freedom of the pressing member 31 during the movement can be eliminated, so that it can only slide along a preset path, thereby ensuring the stability and reliability of the locking mechanism, and avoiding locking failure caused by the displacement of the pressing member 31; and the coordinated use of the first guide portion 38 and the sliding member 39 can make the movement of the pressing member 31 smoother. Regardless of pushing or pulling the hanging arm 21, the pressing member 31 can move quickly and smoothly along the first guide portion 38, thereby reducing friction and resistance during operation, thereby improving the user's operating experience.

[0058] Preferably, in the embodiment of the present invention, a first guide portion 38 is provided on the pressing member 31 , and a sliding member 39 is provided on the mounting mechanism 10 .

[0059] like Figure 4As shown, in the embodiment of the present invention, the mounting mechanism 10 is provided with a second guide portion 40, and the locking member 32 is slidably arranged on the second guide portion 40 to limit the moving direction of the locking member 32. In this way, the moving direction of the locking member 32 can be precisely controlled, and the degree of freedom of the locking member 32 during the movement process can be eliminated, so that it can only slide along the preset path, thereby ensuring the stability and reliability of the locking mechanism, and avoiding the locking failure caused by the displacement of the locking member 32; and the cooperation of the second guide portion 40 and the locking member 32 can make the movement of the pressing member 31 smoother, whether pushing or pulling the hanging arm 21, the locking member 32 can move quickly and smoothly along the second guide portion 40, thereby reducing the friction and resistance during the operation process, thereby improving the user's operating experience.

[0060] like Figure 2 As shown, in an embodiment of the present invention, the hanging arm assembly also includes two connecting rod members 41 arranged at intervals, one end of each connecting rod member 41 is pivotally connected to the hanging arm 21, and the other end of each connecting rod member 41 is pivotally connected to the mounting mechanism 10, so that the mounting mechanism 10, the two connecting rod members 41 and the hanging arm 21 form a quadrilateral structure.

[0061] Through the above-mentioned arrangement, the arm 21 moves in the form of a parallelogram mechanism, which can ensure the fast and smooth switching of the distance between the arm 21 and the wall, and can avoid the jamming or unsmoothness that may occur in the movement of the traditional arm 21; and the geometric characteristics of the parallelogram enable it to resist deformation by external forces, thereby ensuring the stability and firmness of the arm 21 in movement, and even if large-size or heavy display equipment is installed, the stability of the bracket can be maintained; and the use of the parallelogram structure can fold or retract the connecting rod member 41 when the arm 21 is close to the wall, thereby reducing the space occupied by the arm assembly.

[0062] like Figure 2 As shown, in an embodiment of the present invention, two holes are provided on the angle adjustment plate, two holes are provided at both ends of the connecting rod member 41, and two holes are provided on the hanging arm 21. The two holes at both ends of the two connecting rod members 41 are respectively connected to the two holes on the angle adjustment plate and the two holes on the hanging arm through four fasteners 18.

[0064] Through the above arrangement, the arm 21 is installed on the adjusting member 12 through two connecting rod members 41. By rotating the adjusting member 12, the pitch angle of the display on the arm 21 can be adjusted. By setting the locking member 13, the user can lock the angle immediately after adjusting it without additional tools or complicated operations, so that the display can remain stable at different angles.

[0065] Preferably, in the embodiment of the present invention, the adjusting member 12 may be an angle adjusting plate.

[0066] Specifically, in an embodiment of the present invention, at least one hole is provided on the locking mechanism 30, at least one hole is provided on the angle adjustment plate, and at least one fastener 18 passes through the two holes at the same time, so that the locking mechanism 30 and the angle adjustment plate are fixed to each other.

[0067] Specifically, in an embodiment of the present invention, a hole is provided on the locking mechanism 30, at least one elongated hole is provided on the angle adjustment plate, the second guide portion 40 is the above-mentioned elongated hole, and the fixed shaft passes through the aforementioned hole and the elongated hole at the same time, so that the fixed shaft can slide in the elongated hole on the angle adjustment plate, and the hole on the locking mechanism 30 follows the fixed shaft to slide in the elongated hole on the angle adjustment plate.

[0068] Specifically, Figure 4 As shown, in an embodiment of the present invention, a protrusion structure is provided on the angle adjustment plate at a position away from the elongated hole, one end of the elastic member 33 is hooked on the protrusion structure, and the other end of the elastic member 33 is hooked on the fixed shaft, so that when there is no external force, the fixed shaft is always on the lower side of the elongated hole on the angle adjustment plate.

[0069] Specifically, Figure 4 As shown, in the embodiment of the present invention, at least one long strip hole is provided on the locking mechanism 30, the first guide portion 38 is the long strip hole, at least one hole is provided on the angle adjustment plate, and at least one fastener 18 passes through the long strip hole and the hole at the same time, so that the locking mechanism 30 can slide on the angle adjustment plate. Among them, at least one long strip hole is provided on the pressing member 31.

[0070] like Figure 2 As shown, in the embodiment of the present invention, the hook member 11 is provided with two arc grooves 14, and the mounting mechanism 10 further comprises two connecting members 15, which pass through the adjusting member 12 and respectively slide in the two arc grooves 14. Thus, by rotating the adjusting member 12, the two connecting members 15 can slide in the two arc grooves 14 respectively, so as to adjust the pitch angle of the display by adjusting the pitch angle of the adjusting member 12.

[0071] Preferably, in the embodiment of the present invention, at least two holes are provided on the angle adjustment plate, the two holes are provided corresponding to the two arc-shaped grooves 14 , and the two holes are used to pass through the two connecting members 15 .

[0072] like Figure 2 As shown, in the embodiment of the present invention, the adjusting member 12 is provided with an arc-shaped avoidance groove 16 , the hook member 11 is provided with a connecting hole 17 , and the locking member 13 passes through the arc-shaped avoidance groove 16 and is connected to the connecting hole 17 .

[0073] In the above technical solution, when the locking member 13 is loosened, the adjusting member 12 can rotate relative to the hook member 11, and the locking member 13 moves along the arc path of the arc avoidance groove 16. When the locking member 13 is tightened, the angle of the adjusting member 12 relative to the hook member 11 cannot change. In this way, it can not only ensure that the adjusting member 12 has a larger angle adjustment range, but also through the cooperation between the locking member 13 and the connecting hole 17, the user can accurately lock the pitch angle of the display.

[0074] Preferably, in an embodiment of the present invention, there is at least one connecting hole 17 , and the connecting hole 17 is a threaded hole, there is at least one arc-shaped avoidance groove 16 , and there is at least one locking member 13 .

[0075] Specifically, Figure 2 and Fig.10 As shown, in the embodiment of the present invention, the hanging arm assembly also includes a wall panel 1 for installation on the wall, the hook member 11 includes a hook 111, a lock buckle 112, a lock buckle spring 113 and a pull rope 114, the lower edge of the lock buckle 112 is provided with a hole, one end of the lock buckle spring 113 is hooked in the hole, one end of the pull rope 114 is knotted on the hole, the hook 111 is provided with at least one hole, the lock buckle 112 is provided with a long strip hole, at least one fastener 18 passes through the hole on the hook 111 and the long strip hole on the lock buckle 112 at the same time The strip hole and the other end of the lock spring 113 make it possible to pull the pull rope 114, the lock 112 moves downward along the long strip hole, and at the same time the lock spring 113 stretches and starts to accumulate force, and then releases the pull rope 114. Under the action of the lock spring 113, the lock 112 returns to its initial position. A protruding structure is provided on the lock 112, and the protruding structure and the hook 111 cooperate with the wall panel 1, so that when the pull rope is pulled, the hook 111 can be detached from the wall panel; when the pull rope is not pulled, the hook 111 cannot be detached from the wall panel.

[0076] like Figure 6As shown, in an embodiment of the present invention, at least one hole is provided on the front shell 44, and at least one hole is provided on the rear shell 43. At least one fastener 18 passes through the two aforementioned holes at the same time, so that the front shell 44 and the rear shell 43 are fixed together, and a cavity is formed between the front shell 44 and the rear shell 43 to accommodate the rotor component 35 and part of the pushing component 34.

[0077] For ease of understanding, the process of switching the locking member 32 between the locked position and the unlocked position can be decomposed to define the state of the pushing member 34: Fig. 9 From left to right in the figure, the states of the pushing member 34 are state 1, state 2, state 3, state 2, state 3, state 1; the angle of the rotor member 35 is defined as: Fig. 9 From left to right in the figure, the angles of the rotor component 35 are angle 1, angle 2, angle 3, angle 4, angle 4, and angle 1, respectively.

[0078] First, when the pushing member 34 is in state 1, the pushing member 34 is pushed upward to the maximum stroke, and the state of the pushing member 34 changes to state 2. During this process, the pushing member 34 drives the rotor member 35 to change from angle 1 to angle 2;

[0079] Second, the pushing member 34 is then pulled downward. Since the rotor member 35 is at angle 2, it will hinder the movement of the pushing member 34, so the state of the pushing member 34 changes to state 3. During this process, the rotor member 35 changes from angle 2 to angle 3.

[0080] Third, the pushing member 34 is pushed upward to the maximum stroke, and the state of the pushing member 34 changes to state 2. During this process, the pushing member 34 drives the rotor member 35 to change from angle 3 to angle 4;

[0081] Fourth, the pushing member 34 is pulled downward again. When the pushing member 34 is in state 3, since the rotor member 35 is at angle 4 at this time, the rotor member 35 will not hinder the movement of the pushing member 34, so the pushing member 34 can continue to move to the minimum stroke, that is, the pushing member 34 returns to state 1; during this process, the pushing member 34 will drive the rotor member 35 to return to angle 1;

[0082] After the above steps, a whole cycle is completed (refer to Fig. 9 , motion decomposition steps diagram).

[0083] It should be noted that the shapes of the rotor member 35 and the pushing member 34 are precisely verified and designed. The rules can be summarized as follows:

[0084] When the pushing member 34 is in state 1, the angle of the rotor member 35 must be angle 1, and the pushing member 34 can be converted from state 1 to state 2; when the pushing member 34 is in state 2, the rotor member 35 is at angle 2, and the pushing member 34 cannot be converted from state 2 to state 1, and when the angle of the rotor member 35 is at angle 4, the pushing member 34 can be converted from state 2 to state 1.

[0085] It should be noted that if Fig. 9 As shown, in an embodiment of the present invention, when the distance between the hanging arm 21 and the mounting mechanism 10 decreases, the fixed axis moves upward; when the distance between the hanging arm 21 and the mounting mechanism 10 increases for the first time, the fixed axis moves downward a short distance (the fixed axis is defined as state B at this time); then again when the distance between the hanging arm 21 and the mounting mechanism 10 decreases, the fixed axis moves upward; when the distance between the hanging arm 21 and the mounting mechanism 10 increases for the second time, the fixed axis moves downward a long distance (the fixed axis is defined as state A at this time); a notch is provided on the hanging arm, the notch forms a locking portion 22, the notch cooperates with the fixed axis in state B, and the notch does not cooperate with the fixed axis in state A, so that when the fixed axis is in state A, the distance between the hanging arm 21 and the mounting mechanism 10 is not restricted from the minimum to the maximum and from the maximum to the minimum; when the fixed axis is in state B, the distance between the hanging arm 21 and the mounting mechanism 10 is restricted from the minimum to the maximum by the fixed axis in state B, so that the distance can only be in a smaller state. When the distance between the hanging arm 21 and the mounting mechanism 10 is at a relatively small position, the hanging arm 21 is restricted by the fixed axis in state B, the distance cannot be increased, and the hanging arm 21 is in a relatively close position; at this time, the hanging arm 21 is pushed inward again to change the distance to the minimum, the fixed axis moves downward, and changes to state A, at which time the distance between the hanging arm 21 and the mounting mechanism 10 can be increased to the maximum state; then the hanging arm 21 is pushed inward again to the minimum position, the fixed axis moves upward, and changes to state B, the hanging arm is restricted by the fixed axis in state B, the hanging arm 21 is in a relatively close position, and a cycle is completed; the basic functions of quickly switching the distance of the display device from the wall and automatically locking and unlocking the device when switching are achieved.

[0086] It should be noted that the present invention provides a hanging arm assembly that can quickly switch the distance from the wall, facilitates wiring, and can automatically lock and unlock when switching the distance from the wall.

[0087] From the above description, it can be seen that the above-mentioned embodiments of the present invention achieve the following technical effects: when the locking member and the locking part are in the locked position of the lock cooperation, it can ensure that the hanging arm is stably fixed in the current position to support the display. The user pushes the hanging arm in the direction of the mounting mechanism, and the movement of the hanging arm will contact the pressing member and apply pressure to move the pressing member on the mounting mechanism. The movement of the pressing member will drive the locking member linked with it to move from the locked position to the unlocked position, release the cooperation between the locking member and the locking part on the hanging arm, so that the hanging arm can be freely away from the mounting mechanism to increase the distance from the wall. At this time, the locking member is in the unlocked position, and the hanging arm is not subject to any locking restrictions, thereby facilitating wiring and adjusting the pitch angle of the hanging arm over a wide range; when the hanging arm needs to be moved back from a position away from the wall to a position close to the wall, the user pushes the hanging arm in the direction of the mounting mechanism again, and the movement of the hanging arm will contact the pressing member and apply pressure to move the pressing member on the mounting mechanism, thereby driving the locking member to move from the unlocked position back to the locked position, and re-lock with the locking part on the hanging arm. In this way, the user only needs to push or pull the hanging arm, without additionally operating the locking or unlocking mechanism, to quickly adjust the distance between the hanging arm and the wall, so that the hanging arm can be close to the wall and support the display, and can be away from the wall to facilitate wiring operations and adjust the pitch angle of the display on the hanging arm in a wide range. The above structure is simple and can reduce production costs. In summary, the hanging arm assembly of the embodiment of the present invention solves the problems of inconvenient wiring of the hanging rack, limited angle adjustment range, high cost and complex structure in the prior art.

For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
