[0002] With the integrated design of furniture, how to achieve the integration and concealment of products such as smart furniture cabinets has always been the key to design. For example, the structure of the panel or cabinet has always been a difficult point in design.

[0003] Existing panels generally adopt a sliding structure or a flip structure. The sliding structure requires a guide rail, so when opened, it takes up a large external space to accommodate the panel.

[0004] However, the panels of commonly used flip structures usually have exposed hinges or the panels need to extend out of the cabinet body to open the furniture storage cavity, which affects the user experience. Summary of the Invention

[0005] The main purpose of the present invention is to propose a hidden panel structure for furniture, which aims to improve the existing furniture panels, hide their rotating shafts, and integrate the panel design. At the same time, when the accommodating cavity is opened, the panel can be extended into the accommodating cavity to reduce the occupancy of the external space and improve the aesthetics of the furniture.

[0006] To achieve the above objectives, the present invention provides a hidden panel structure for furniture, comprising:

[0007] The handrail seat is a cavity with an opening at the upper end, and the rear wall of the cavity is arc-shaped and encloses a guide cavity;

[0008] The panel has cranks extending in an arc shape on both sides of the rear end of the panel, and the cranks include an arc portion and a horizontal portion.

[0009] The horizontal portion is parallel to the panel.

[0010] The end of the horizontal portion is provided with a pivot portion, and the pivot portion is rotatably mounted on both sides of the handrail seat;

[0011] The rear end of the panel is fitted into the guide cavity;

[0012] Locking devices, which are provided on both sides of the handrail and are used to lock when the panel blocks the opening;

[0013] When the locking device is unlocked, the panel can be driven by the elastic member to extend into the cavity and its upper end portion can be extended.

[0014] In the actual design, the armrest with an open cavity and the panel cooperate to hide the panel when it is open. At the same time, when the opening is closed, the armrest and the panel are integrated, which improves the design aesthetics of the furniture.

[0015] In the actual design, the handrail is designed into a guide cavity and is offset against the rear of the panel, thereby improving the rotational stability and guiding stability of the panel and enhancing the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0040] like Figures 1 to 8 As shown, a hidden panel structure for furniture, comprising:

[0041] The handrail base 1 is a cavity 12 with an opening 11 at the upper end, and the rear wall of the cavity 12 is arc-shaped and encloses a guide cavity 4;

[0042] Panel 2, the rear end of the panel 2 has curved extensions on both sides with cranks 20, the cranks 20 include a curved portion 21 and a horizontal portion 22,

[0043] The horizontal portion 22 is parallel to the panel 2.

[0044] The end of the horizontal portion 22 is provided with a pivot portion 3, and the pivot portion 3 is rotatably mounted on both sides of the handrail;

[0045] The rear end of the panel 2 is fitted into the guide cavity 4;

[0046] Locking devices, which are provided on both sides of the handrail 1 and are used to lock the panel 2 when it blocks the opening 11;

[0047] When the locking device is unlocked, the panel 2 can be driven by the elastic member to extend into the cavity 12 and have its upper end portion extended.

[0048] In the actual design, the armrest 1 with the opening 11 and the cavity 12 cooperates with the panel 2, so that the panel 2 can be hidden when it is opened. At the same time, when the opening 11 is closed, the armrest 1 and the panel 2 are integrated, thereby improving the design aesthetics of the furniture.

[0049] In the actual design, the guide cavity 4 is designed on the handrail seat 1 and is against the rear part of the panel 2, thereby improving the rotation stability and guiding stability of the panel 2 and improving the user experience.

[0050] Specifically, the panel 2 and the crank 20 are integrally formed. Using the integrally formed panel 2 can improve the overall structural stability and reduce the number of assembly steps.

[0051] In the embodiment of the present invention, a guide portion 41 is extended backward from the rear end of the panel 2. The guide portion 41 is in contact with the wall surface of the guide cavity 4 and is lower than the upper wall of the panel 2.

[0052] The guide groove is provided with a plurality of convex circles 7 from top to bottom, and the convex circles are arranged to lock the diameter of the assembly from top to bottom;

[0053] When the panel 2 blocks the opening 11 , it abuts against the inner end of the opening 11 , wherein the guide portion 41 can play a guiding role as well as a position limiting role.

[0054] Specifically, the rear wall of the guide portion 41 is composed of a plurality of spaced-apart protrusions, and the guide cavity 4 is provided with a guide groove 42 extending along its arc length. The protrusion extends into the guide groove 42, thereby realizing the guidance of the panel 2. Therefore, compared with the existing design, it does not require additional guide structures (such as guide rods, etc.), improves the integration of the design and the stability of the structure, and avoids wear during the sliding process.

[0055] In the embodiment of the present invention, a convex strip 7 is provided on the lower wall of the front portion of the panel 2 , and the convex strip is used to abut against the upper wall of the rear portion of the cavity 12 , thereby limiting the position of the panel 2 when it is in the open state.

[0056] Specifically, the locking device includes elastic locking chambers 51 provided on both sides of the handrail 1 and a locking bar provided on the crank 20.

[0057] The locking strip and the elastic lock cavity both extend obliquely, and the locking strip can swing between a position extending into the elastic lock cavity 51 and a position withdrawn from the elastic lock cavity 51. This achieves both unlocking and locking, achieving both position limiting and locking, and cooperating with the guide portion 41 to reduce the load and pressure on the elastic lock cavity 51.

[0058] In the embodiment of the present invention, a driving gear 31 is provided on the outer peripheral wall of the pivoting portion 3.

[0059] The pivoting portion 3 is pivotally mounted on the cavity 12 via a rotating shaft.

[0060] The two sides of the cavity 12 are provided with a passive gear 32 that matches the active gear 31.

[0061] The driven gear 32 is pivotally mounted on the side wall of the cavity 12 and can rotate along with the swing of the driving gear 31 .

[0062] Specifically, a torsion spring 6 is provided in the passive gear 32 or the active gear. When the panel 2 swings toward the closed state, the active gear 31 can apply a curling force to the torsion spring 6 and apply pressure to the torsion spring 6.

[0063] When the panel 2 is opened, the torsion spring 6 can apply a rotational force to the passive gear 32 and drive the panel 2 to swing toward the open state, thereby realizing the automatic opening of the panel 2.

[0064] In an embodiment of the present invention, a spring sheet 61 is further provided on one side of the driving gear 31. The spring sheet abuts against the tooth portion of the driving gear 31 and can be in elastic contact under elastic action, thereby providing a damping effect on the driving gear 31. Of course, the specific damping can also be provided between the protrusion and the groove, wherein the spring sheet can also be implemented by a damping pad, thereby achieving flexible opening and avoiding the problem of bouncing of the torsion spring 6 at the moment of opening.

[0065] The locking device includes a housing 8, a guide slot 80 provided in the housing 8, a sliding block 81 slidably mounted in the guide slot 80, and a locking slot provided in the housing 8;

[0066] A top spring 86 is provided between the sliding block 81 and the guide slot 80 , and the top spring is used to exert an upward elastic force on the sliding block 81 ;

[0067] The side wall of the housing 8 is provided with a locking groove, and a hook spring 83 is provided between the sliding block 81 and the locking groove.

[0068] The lock slot includes a locking channel 821 and an unlocking channel 822, and a locking groove is provided between the locking channel 821 and the unlocking channel.

[0069] The upper end of the hook spring 83 is hooked on the sliding block 81 and can swing along the swing block from the locking channel to the unlocking channel with the pivot point as the fulcrum 831. The other end is a sliding hook 832, which slides along the length direction of the guide groove 80.

[0070] The locking groove is provided on the locking portion 85, and the locking groove is concave. The two sides of the locking portion 85 are a first inclined surface 851 and a second inclined surface 852. The first inclined surface cooperates with the locking channel, and the second inclined surface is adjacent to the unlocking channel.

[0071] The sliding block 81 is provided with claws 811 at both ends, the upper ends of the claws 811 extend outwards, and the inner wall of the sliding groove is provided with a limit block 84, and the two claws 811 form an elastic lock cavity;

[0072] When the claw 811 extends into the sliding slot, the limiting block 84 abuts against the outer wall of the claw 811 and applies pressure to the claws 811 to move them closer to each other.

[0073] The improved elastic locking cavity can stably lock the elastic strip.

[0074] In actual operation, the sliding hook 832 of the hook spring 83 will swing toward the locking channel, so that the sliding hook 832 extends from the first inclined surface into the locking groove to lock.

[0075] When pressing force is applied, the sliding hook 832 disengages from the locking groove 850 and unlocks the channel, and the sliding block 81 extends out of the sliding groove.

[0076] This in turn drives the panel to be unlocked. This design improves the problem that the existing locking structure is unstable and cannot pop out automatically.

[0077] The ends of the clamping jaws are elliptical in shape, which allows the locking bar to be inserted and to abut against the limiting portion, thereby achieving mutual closure and clamping.

[0078] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structural transformation made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
