Description

Technical Field

[0001] This invention relates to a home hardware accessory, specifically a connector for a concealed corner cabinet. Background Technology

[0002] Corner cabinets are an indispensable part of ordinary furniture cabinets. Older corner cabinets use a fixed shelf structure with a rounded, fan-shaped opening. Users place items on the shelves for storage and display. However, these cabinets are mostly open and cannot be fitted with doors, making it easy for dust to accumulate inside. Furthermore, cabinets that are constantly open offer little privacy. Therefore, further improvements are necessary. Summary of the Invention

[0003] The purpose of this invention is to overcome the shortcomings of existing technologies and provide a connector for a hidden corner cabinet that is simple in structure, easy to use, and capable of opening and closing while maintaining its aesthetics and privacy.

[0004] The objective of this invention is achieved in the following manner: a connector for an electrically driven concealed corner cabinet, comprising a fixed base and a movable base, wherein a linear slider is mounted on the fixed base via a linear guide rail, and the linear slider slides on the linear guide rail; the linear slider is connected to the movable base via a rotating shaft, and the movable base can rotate around the rotating shaft; a guide rail and a guide rack are mounted on the movable base.

[0005] Correspondingly: the fixed seat is equipped with a power guide block and a power drive gear. The power guide block cooperates with the guide rail, and the power drive gear meshes with the guide rack. The power drive gear drives the movable seat to rotate around the rotating shaft, and the power guide block drives the linear slider to slide on the linear guide rail.

[0006] The guide rail and guide rack are arranged in an "S" shape and are distributed in parallel.

[0007] The movable seat is disc-shaped, and the trajectory of the guide rack is tangent to its outer circle.

[0008] The guide rack is arranged symmetrically about the center of the movable seat.

[0009] The power drive gear is rotatably mounted on the power frame, which is connected to the fixed base. An electric motor is installed on the power frame to drive the power drive gear to rotate.

[0010] Position switches are also provided on both sides of the power frame. Correspondingly, limit blocks are provided on the guide rack to cooperate with the position switches and limit the movement stroke of the movable seat.

[0011] The power guide block consists of a first guide wheel and a second guide wheel clamped on both sides of the guide rail. The power drive gear is connected to the first guide wheel and the second guide wheel through a rotating seat, and the rotating seat can rotate relative to the power drive gear.

[0012] The first guide wheel and the second guide wheel are connected to the rotating seat through a hinge shaft, and the first guide wheel and the second guide wheel rotate around the hinge shaft.

[0013] The linear guide rails are provided in two sets, which are symmetrically installed on both sides of the linear slider.

[0014] The beneficial effects of this invention are: 1. Simple structure, low production cost, and improved market competitiveness. 2. This connector can realize two states for the corner cabinet: opening outwards and rotating inwards to close, providing convenience for users. 3. The movement is driven by an electric device, ensuring stable and reliable movement speed, thereby preventing items inside the cabinet from tipping over due to centrifugal force during rotation. 4. The electric device has a self-locking capability, which can lock the cabinet and, in conjunction with the electronic control system, provides good anti-theft performance.

[0025] The present invention will be further described in detail below with reference to the accompanying drawings. A connector for an electrically driven concealed corner cabinet includes a fixed base 1 and a movable base 2. A linear slider 4 is mounted on the fixed base 1 via a linear guide rail 3, and the linear slider 4 slides on the linear guide rail 3. The linear slider 4 is connected to the movable base 2 via a rotating shaft 5, and the movable base 2 can rotate around the rotating shaft 5. A guide rail 6 and a guide rack 7 are mounted on the movable base 2.

[0026] Correspondingly: the fixed seat 1 is equipped with a power guide block 8 and a power drive gear 9. The power guide block 8 cooperates with the guide rail 6, and the power drive gear 9 meshes with the guide rack 7. The power drive gear 9 drives the movable seat 2 to rotate around the rotating shaft 5, and the power guide block 8 drives the linear slider 4 to slide on the linear guide rail 3.

[0027] The guide rail 6 and guide rack 7 are arranged in an "S" shape and are distributed in parallel.

[0028] The movable seat 2 is disc-shaped, and the trajectory of the guide rack 7 is tangent to its outer circle.

[0029] The guide rack 7 is arranged symmetrically about the center of the movable seat 2.

[0030] The power drive gear 9 is rotatably mounted on the power frame 91, which is connected to the fixed base 1. An electric motor 92 is installed on the power frame 91 to drive the power drive gear 9 to rotate.

[0031] The power frame 91 is also provided with position switches 93 on both sides. Correspondingly, the guide rack 7 is provided with limit blocks 94 that cooperate with the position switches 93 to limit the movement stroke of the movable seat 2.

[0032] The power guide block 8 consists of a first guide wheel 81 and a second guide wheel 82 clamped on both sides of the guide rail 6. The power drive gear 9 is connected to the first guide wheel 81 and the second guide wheel 82 through a rotating seat 83, which can rotate relative to the power drive gear 9.

[0033] The first guide wheel 81 and the second guide wheel 82 are connected to the rotating seat 83 via a hinge shaft 84, and the first guide wheel 81 and the second guide wheel 82 rotate around the hinge shaft 84.

[0034] The linear guide rail 3 is provided in two sets, which are symmetrically installed on both sides of the linear slider.

[0035] Working principle: such as Figure 1-4 As shown, when the connector in this case is used with the corner cabinet 12, a set of connectors needs to be installed at both the top and bottom ends of the corner cabinet 12. The movable part of the connector is fixed to the top and bottom plates of the corner cabinet 12, and the fixed part of the connector is fixed to the cabinet body 13. By connecting the two sets of connectors, the corner cabinet 12 can be rotatably installed on the cabinet body 13.

[0036] When the user rotates the corner cabinet, the control system controls the opening and closing of the cabinet by controlling the forward and reverse rotation of the motor 92. The specific actions are as follows: When the motor 92 rotates, it drives the drive gear 9 to rotate via a reduction mechanism. The drive gear 9, in turn, drives the guide rack meshing with it to move relative to the drive gear, thereby moving the movable seat. During this movement, the movable seat is subjected to the mutual pressing action of the guide rail and the power guide block, causing it to rotate around the rotating shaft 5 while simultaneously sliding on the linear guide rail via a linear slider. Through the coordination of linear and rotational motions, the main body of the corner cabinet moves outward along the linear guide rail during rotation, preventing collision with the cabinet body 13. After the corner cabinet reaches its rotation position, it moves inward and rotates synchronously under the action of the guide rail, ultimately achieving a 180° rotation of the corner cabinet 12. The user can automatically control the movement of the rotating corner cabinet 12 through the electrical control system, enabling the cabinet to be displayed with its opening facing outwards or concealed with its opening facing inwards. Therefore, users can choose to display the cabinet with the opening facing outwards or hide it with the opening facing inwards, depending on their actual needs. This serves to open and close the cabinet, providing privacy while preventing dust accumulation inside the corner cabinet and keeping the interior of the cabinet clean.

[0037] It's worth noting that the corner cabinet in this case uses an electric drive mechanism for rotation. This allows for its application in large and heavy-duty corner cabinets. Secondly, the electric drive makes opening and closing the cabinet more convenient and effortless, adding a touch of high-tech sophistication. Furthermore, the speed of the electric opening and closing can be adjusted via the control system, allowing for speed regulation based on user needs and adaptability to different locations. Additionally, through optimized control programming, the cabinet operates at low speed at the start and near the end of rotation, while high speed is used during the middle of the rotation. This ensures rapid opening and closing while preventing items inside the cabinet from tipping over due to excessive acceleration. Moreover, with the electric drive, the control system can also be used for opening and closing via network, card swipe, or key swipe, eliminating the need for an external keyhole and thus providing a degree of security and theft prevention.

[0038] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this invention.
