Description

Technical Field

[0001] The utility model relates to the field of home furnishing equipment, and in particular to a hidden door opening device and a TV wall structure. Background Art

[0002] With the changes in installation environments and renovation upgrades, many TV walls are now designed with built-in TV installations. At the same time, retractable TV stands have appeared to allow the TV to be stored in the TV wall. After that, decorative door panels are set at the original TV position to cover the TV, making the TV wall more beautiful overall.

[0003] At this point, a problem arises. Existing TV walls generally use guide rails that simply move decorative door panels up and down or left and right. When the decorative door panels reach the position to block the TV, there is a certain front-to-back difference with the overall external surface of the TV wall, making the TV wall as a whole look sunken inward, which is not beautiful enough.

[0004] Therefore, a device is needed to enable the decorative door panel to extend forward and be flush with the exterior of the TV wall when it is moved to a position to block the TV. Utility Model Content

[0005] In order to overcome the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a device which enables the decorative door panel to extend forward and be flush with the exterior of the TV wall when it is moved to a position to block the TV.

[0006] The technical solution adopted by the utility model to solve its technical problems is:

[0007] A hidden door opening device comprises a guide rail assembly and a slide block assembly;

[0008] The guide rail assembly includes a guide rail and a first guide rail;

[0009] The slider assembly includes a first slider and a second slider for mounting the door panel;

[0010] The first slider is slidably disposed on the first guide rail, and the first slider is provided with a second guide rail disposed along the front-rear direction; the second slider is slidably disposed on the second guide rail;

[0011] The second sliding block is provided with a linkage member cooperating with the guide rail;

[0012] In the later stage when the guide rail assembly drives the door panel to close, the guide rail guides the second slider to move forward through the linkage member;

[0013] In the early stage when the guide rail assembly drives the door panel to open, the guide rail guides the second sliding block to move backward through the linkage member.

[0014] Specifically, the forward and backward directions of the door panel mentioned here are, forward is the direction of extending the door panel so that the door panel is flush with the TV wall; backward is the direction of retracting the door panel, that is, the direction of the door panel being recessed inward relative to the TV wall.

[0015] Specifically, the opening and closing directions of the door panels described here are classified into multiple situations. When there is only one door panel, the closing direction of the door panel refers to the direction in which the door panel moves from a position away from the TV shielding position to a position in which the TV shielding position is moved, generally up / down / left / right, while the opening direction of the door panel is the opposite. When there are two door panels, the closing direction of the door panel refers to the direction in which the two door panels move toward each other, and the opening direction of the door panel refers to the direction in which the two door panels move away from each other.

[0016] By adopting the above technical solution, taking the door panel moving upward as the opening direction and moving downward as the closing direction as an example, the guide rail and the first rail are arranged vertically in parallel, the first slider is directly slid up and down on the first rail; the second slider is directly slid forward and backward on the first rail, and the second slider is controlled by the guide rail to move forward and backward through the linkage. In the process of closing the door panel, the power member drives the second slider or the first slider to move downward (preferably the first slider, because the first slider does not move forward and backward during the whole process), the guide rail is located at a relatively rearward position in the front section extending downward, and gradually adjusts to a relatively forward position in the rear section extending downward, and guides the second slider and the door panel to move forward through the linkage. As a result, when the door panel moves to the position of blocking the TV, it can extend forward and be flush with the surface of the TV wall.

[0017] As an improved solution, it also includes a power member, which drives the slider assembly to move on the guide rail assembly; the first guide rail is a straight line, and is arranged along the direction of opening and closing of the door panel, and the linkage member is a linkage pin, one end of which is connected to the second slider, and the other end extends into the guide rail; the travel route of the guide rail turns toward the extending direction of the door panel, that is, turns forward, in the later stage when the guide rail assembly drives the door panel to close.

[0018] By adopting the above technical solution, the movement of the second slider in the telescopic direction is synchronized with the movement of the first slider in the opening and closing direction, and the structural reliability is strong and not prone to failure.

[0019] As an improved solution, it also includes a power piece, which drives the slider assembly to move on the guide rail assembly; the first guide rail is straight and is arranged along the direction of opening and closing of the door panel, and the linkage piece includes a third slider, a linkage rod, and a linkage pin; one end of the linkage pin is connected to the second slider, and the other end extends into the guide rail; one end of the linkage rod is connected to the linkage pin, and the other end is rotatably connected to the third slider; the third slider is slidably arranged on the first guide rail / on the first slider along the direction of the first guide rail.

[0020] Specifically, the first slider is provided with an active area adapted to the third slider in the opening and closing direction of the door panel, and when the third slider slides in the opening and closing direction of the door panel within the active area, the first slider will not slide in the opening and closing direction of the door panel; and the third slider can still drive the second slider to move in the extension and retraction direction of the door panel through the linkage rod and the linkage pin, in cooperation with the guide rail.

[0021] By adopting the above technical solution, the movement of the second slider in the telescopic direction and the movement of the first slider in the opening and closing direction can be performed independently of each other, taking the downward movement in the closing direction of the door panel as an example:

[0022] In the first half, the power piece is connected to the third slider, driving the third slider to move downward. At this time, the third slider is above the active area, and the first slider also moves downward under the action of gravity; at this time, the guide rail is in the rear position, and the second slider and the door panel are also in the rear position.

[0023] When the first slider moves to the bottom of the first guide rail, the door panel has reached the position to block the TV. This is the node of state transition. At this time, the third slider is above the active area, and the first slider stops moving because it reaches the bottom. At this time, the guide rail is in the rear position, the second slider and the door panel are also in the rear position, and the door closing action enters the second half.

[0024] In the second half, the power part is connected to the third slider, driving the third slider to move downward from the top in the active area. At this time, the first slider stops moving because it reaches the bottom, so the second slider and the door panel remain in the same position in the up and down directions; but the third slider pushes the linkage rod, thereby driving the linkage pin to move downward on the guide rail. At this time, the guide rail turns forward from the rear position, so that the second slider at the other end of the linkage pin also moves forward following the position of the guide rail, and finally makes the door panel installed on the second slider reach a position flush with the outer surface of the TV wall.

[0025] This allows the door panel to first fall straight down and then extend outward during closing, and the moving trajectory can turn at a right angle; similarly, the door panel first retracts straight in and then rises straight up during opening. The size requirements for the TV wall and door panel are reduced, and it can adapt to more types of installation environments, and the movement during opening and closing is smoother.

[0026] As an improved solution, the travel path of the guide rail turns in an arc shape toward the extension direction of the door panel in the later stage when the guide rail assembly drives the door panel to close.

[0027] By adopting the above technical solution, the speed at which the second slider and the door panel extend and move is first slow and then accelerated, so that the speed at which the door panel extends forward can change evenly, the movement is smoother, the force change of the guide rail is smoother, and the service life of the guide rail is increased.

[0028] As an improved solution, the travel path of the guide rail, in the later stage when the guide rail assembly drives the door panel to close, turns in a broken line shape toward the extension direction of the door panel.

[0029] By adopting the above technical solution, the speed at which the second sliding block and the door panel extend and move is constant, which can simplify the handling of the linkage pin and increase the service life of the linkage pin.

[0030] As an improved solution, the power component includes: a transmission motor and a transmission belt; the transmission motor is connected to the second slider / first slider through the transmission belt; a number of steering mechanisms are provided on the guide rail assembly, and the transmission belt cooperates with the steering mechanism to form a closed loop, and drives the second slider / first slider to slide along the opening and closing direction of the door panel.

[0031] Specifically, the transmission motor used here can also be replaced by other power sources that can drive the transmission belt to move, such as a fuel engine, a steam engine, a hand-cranked drive, etc. The combination of the transmission belt and the steering mechanism can be: a smooth belt and a smooth fixed pulley, a rack belt and a gear, a chain and a gear, and other alternatives that can play the same role.

[0032] As an improved solution, the power component includes: a transmission motor and a transmission belt; the transmission motor is connected to the third slider through the transmission belt; a number of steering mechanisms are provided on the guide rail assembly, the transmission belt cooperates with the steering mechanism to form a closed loop, and drives the third slider to slide along the opening and closing direction of the door panel.

[0033] As an improved solution, the guide rail assembly is also provided with a tensioner, and the tensioner is provided with a steering mechanism, and the transmission belt moves through the steering mechanism on the tensioner; the tensioner is movably arranged on the guide rail assembly, and the tightness of the transmission belt can be adjusted by moving on the guide rail assembly.

[0034] Specifically, the technical solution of the present application is currently preferably to use a fixed pulley as a steering mechanism, a flat belt as a transmission belt, and a tensioner as a sliding mounting seat slidably arranged on a guide rail assembly.

[0035] By adopting the above technical solution, when the tensioning member slides on the guide rail assembly, the transmission belt needs to pass through the steering mechanism on the tensioning member and then make a circle back. In this process, the path to be passed becomes longer, and the transmission belt is tightened. Similarly, the reverse operation will loosen the transmission belt.

[0036] As an improved solution, the guide rail assembly includes two groups of guide rails arranged opposite to each other and a first guide rail; slider assemblies are respectively arranged opposite to each other on the two guide rail assemblies, and the power member also includes a synchronization rope; the synchronization rope is simultaneously connected to the two slider assemblies in transmission, and drives the two slider assemblies to synchronously approach or move away from each other.

[0037] By adopting the above technical solution, the transmission belt pulls one of the slider assemblies, and the transmission rope pulls the other slider assembly to slide synchronously, thereby achieving the door closing effect of the two slider assemblies approaching each other synchronously and the door opening effect of the two sliding assemblies moving away from each other synchronously.

[0038] A TV wall structure comprises a TV wall body and a decorative door panel, wherein the TV wall body is provided with a hole matching the decorative door panel; the decorative door panel is connected to a position matching the hole through the hidden door opening device as described above.

[0039] By adopting the above technical solution, the TV wall is provided with a hole matching the decorative door panel. When the door panel is in the open state, it is hidden inside the TV wall and adjacent to the hole. When the door panel needs to be switched to the closed state, the power part is used to drive the hidden door opening device to move the door panel to a position to block the TV, and drive the door panel to extend forward to be flush with the exterior of the TV wall.

[0040] Compared with the prior art, the beneficial effects of the utility model are:

[0041] Taking the door panel moving upward as the opening direction and moving downward as the closing direction as an example, the guide rail and the first rail are arranged vertically in parallel, the first slider is directly arranged on the first rail for sliding up and down; the second slider is directly arranged on the first rail for sliding forward and backward, and the second slider is controlled by the guide rail to move forward and backward through the linkage. In the process of closing the door panel, the power member drives the second slider or the first slider to move downward (preferably the first slider, because the first slider does not move forward and backward during the whole process), the guide rail is located at a relatively rearward position in the front section extending downward, and gradually adjusts to a relatively forward position in the rear section extending downward, and guides the second slider and the door panel to move forward through the linkage. As a result, when the door panel moves to the position of blocking the TV, it can extend forward and be flush with the surface of the TV wall. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] Implementation case 1:

[0067] As attached Figure 1-14 As shown, a hidden door opening device is mainly composed of three parts: a power part 1, a guide rail assembly 2, and a slider assembly 3.

[0068] The first part is a power member 1 , which includes a transmission motor 11 provided as a power source, and a transmission rod arranged on the transmission motor 11 , and the transmission rod extends to the slider assembly 3 .

[0069] The second part is the guide rail assembly 2, which is divided into two parts with different functions. The first part is Figure 1 As shown, the middle part is a guide rail 6 symmetrically arranged in the upper and lower parts, and the second part is a first guide rail 7 arranged in the upper and lower directions between the two sides of the guide rail 6. Fixed pulleys as a steering mechanism 13 are arranged along the four corner vertices of the guide rail assembly 2 on the first guide rail 7. The transmission belt 12 and the synchronous rope 15 pass through these four fixed pulleys to form a rectangular moving path as a whole. At least one of the fixed pulleys is driven by the transmission rod so that the transmission belt 12 and the synchronous rope 15 can reciprocate. The two first guide rails 7 are arranged in the vertical direction. The guide rail 6 is relatively far away from the middle of the first guide rail 7. The extension direction of the first guide rail 7 is parallel to each other and is located at a relatively rear position; when the guide rail 6 approaches the middle of the first guide rail 7, its extension direction turns toward the front position.

[0070] The third part is the slider assembly 3, which is specifically divided into a second slider 4, a first slider 5, and a third slider 10; first is the first slider 5, both sides of which are slidably arranged on the first guide rail 7 and will not move in the front-rear direction.

[0071] Next is the second slider 4, which is provided with a door panel mounting position 16. The door panel is directly mounted on the door panel mounting position 16 and moves with the second slider 4. The second slider 4 is slidably mounted on the first slider 5 along the front-to-back direction. On the other hand, the second slider 4 is connected with a linkage pin 8 facing the bottom of the guide rail assembly 2. The linkage pin 8 passes through the through slot on the first slider 5 and is inserted into the guide rail 6. Based on the action of the linkage pin 8, the front-to-back movement of the second slider 4 depends on the position change of the guide rail 6 in the front-to-back direction when the second slider 4 moves up and down.

[0072] Next is the third slider 10, which is clamped between the first slider 5 and the first guide rail 7, and is connected to the linkage pin 8 through the linkage rod 9. The third slider 10 can slide up and down within a range covered by the first slider 5 without affecting the up and down movement of the first slider 5.

[0073] Therefore, the position and connection relationship of the third slider 10 enable the overall movement of the second slider 4 to be divided into two stages, as shown in the attached figure. Figure 5-10 As shown in the figure, from the door panel opening to the door panel closing process:

[0074] In the first section, the second slider 4 moves upward in the vertical direction along with the first slider 5 and does not move in the front-to-back direction until the first slider 5 reaches the end of the upward movement. In this process, since the path of the guide rail 6 is always parallel to the first guide rail 7, the second slider 4 does not move in the front-to-back direction.

[0075] Then, since the first slider 5 can no longer move upward, the vertical movement of the door panel has stopped. At this time, the third slider 10 is driven by the transmission belt 12 or the synchronization rope 15 and can continue to move upward, and push the linkage pin 8 through the linkage rod 9, thereby moving the second slider 4 connected to the linkage pin 8 forward, causing the door panel to extend forward and finally reach a position flush with the outer surface of the TV wall.

[0076] The function of the third slider 10 here is that, if there is no third slider 10 and linkage rod 9, the last forward extension of the guide rail 6 must be synchronized with the upward movement of the guide rail 6, which will result in a large gap between the door panel and the exterior of the TV wall to smoothly complete the movement. The large gap is not beautiful on the one hand, and it is easy for water vapor, dust and small insects to enter the interior of the TV cabinet on the other hand, which is not conducive to long-term use. The third slider 10 can continue to push the second slider 4 to move on the guide rail 6 after the first slider 5 stops moving in the vertical direction, which can form a division of labor. The first slider 5 can only be responsible for driving the second slider 4 to move in the vertical direction, while the third slider 10 is responsible for driving the second slider 4 to move in the front and rear directions.

[0077] In this embodiment, the relative positional relationship between the guide rail assembly 2 and the slider assembly 3 after assembly is as shown in the attached figure. Fig.11 As shown, the guide rail 6 and the first guide rail 7 are at the same horizontal height, and the transmission belt 12 and the synchronous rope 15 are also arranged at this height. Starting from the first guide rail 7, the third slider 10, the first slider 5, the second slider 4, and the door panel mounting position 16 on the second slider 4 are arranged upward in sequence. Among them, the linkage pin 8 passes through the first slider 5 from the bottom of the second slider 4 at the top, is connected to the linkage rod 9, and finally extends to the height of the guide rail 6. The third slider 10 can be directly slidably set on the first guide rail 7 as shown in the figure, and can also be directly matched with the first slider 5 and slidably set on the first slider 5. The working principle is actually the same.

[0078] In order to adjust the tightness of the transmission belt 12, as shown in the attached Fig.12 As shown, in this embodiment, a tensioning member 14 is provided at the upper and lower ends of the guide rail assembly 2. The tensioning member 14 is actually a movable shaft that can be adjusted in the upper and lower directions on the guide rail assembly 2. A pulley is sleeved on the outer periphery of the movable shaft, and the transmission belt 12 also moves through the pulley sleeved by the movable shaft. When the transmission belt 12 needs to be tightened, it is only necessary to adjust the position of the movable shaft upwards in the figure to increase the distance that the transmission belt 12 needs to travel for one circle, thereby achieving the effect of tightening the transmission belt 12. To loosen the transmission belt 12, it is only necessary to adjust the position of the movable shaft downwards.

[0079] In summary, after reading the utility model document, ordinary technicians in this field can make various other corresponding transformation schemes based on the technical scheme and technical concept of the utility model without creative mental labor, and different application scenarios all fall within the scope of protection of the utility model.
