Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically to an engaging electric hinge device. Background Technology

[0002] Hinges are widely used in furniture and appliances. A typical hinge structure includes a mounting base on the door, a fixed base on the door housing, and a transmission assembly connecting the mounting base and the fixed base. This transmission assembly allows the mounting base to open and close on the fixed base, thus opening and closing the door on the door housing. However, when the door is under heavy load, opening and closing becomes difficult, reducing the product's usability.

[0003] To address this, existing hinges are equipped with a drive unit that can apply torque to the door body via at least one force transmission device, thereby facilitating the automatic opening and closing of the door within the housing.

[0004] However, the electric hinges described above have the following shortcomings in practical applications:

[0005] 1) Existing hinge transmission components have complex structures, poor transmission stability, and a large size due to the combination of drive unit and force transmission device, making them unsuitable for other smaller furniture and appliances, thus limiting their application.

[0006] 2) The transmission components, drive units, and force transmitters of existing hinges are mostly assembled as a whole, which makes assembly complex, difficult to disassemble, inconvenient to maintain and replace, and reduces the service life of the product. Utility Model Content

[0007] The purpose of this invention is to overcome the shortcomings of the prior art and provide an interlocking electric hinge device with a simple structure, an interlocking push method, smooth transmission, stable connection, reliability and practicality, and easy assembly and disassembly, convenient maintenance and replacement, thereby improving the product's performance.

[0008] The objective of this invention is achieved as follows: A meshing electric hinge device includes a fixed base installed on a cabinet, a base installed on a door, and a linkage transmission assembly hinged between the fixed base and the base. The door is equipped with a drive device, which includes a drive motor and a linkage assembly. The linkage assembly has a driving tooth, and the linkage transmission assembly has a driven tooth. The driving tooth and the driven tooth are adapted to mesh and connect. The drive motor is mounted on the door, and its output shaft is connected to the linkage assembly. When the drive motor operates, it drives the linkage assembly to move, causing the driving tooth and the driven tooth to rotate relative to each other, thereby opening or closing the linkage transmission assembly and causing the base to be driven to open and close against the fixed base.

[0009] Based on the above optimization, the linkage transmission assembly includes a main beam, a secondary beam, a first connecting rod, and a second connecting rod. The connecting ends of the main beam and the secondary beam are respectively hinged to a fixed base. The connecting ends of the first connecting rod and the second connecting rod are respectively hinged to the middle part and the swinging part of the main beam. The swinging end of the secondary beam is hinged to the middle part of the first connecting rod. The swinging ends of the first connecting rod and the second connecting rod are hinged to a base. The driven tooth is integrally formed at the end of the second connecting rod and meshes with the driving tooth.

[0010] Based on the above optimization, a limiting rod is provided between the active tooth and the driven tooth to prevent the linkage assembly from separating from the second link. The two ends of the limiting rod are respectively hinged to the active tooth and the driven tooth.

[0011] Based on the above optimization, the main beam, the secondary beam, the first connecting rod, and the second connecting rod, driven by the drive motor, form an electric four-bar linkage that can be unfolded or folded between the fixed seat and the base.

[0012] Based on the above optimization, the linkage assembly includes a linkage screw, a sliding block, and a push rod. The linkage screw is equipped with a reduction clutch connected to the drive motor. The sliding block is threaded onto the linkage screw. One end of the push rod is connected to the sliding block, and the other end of the push rod is connected to the swinging part of the beam. The active gear is integrally formed on the end of the push rod.

[0013] Based on the above optimization, the drive device further includes a mounting shell, which has a mounting cavity for mounting the drive motor and the reduction clutch, and a positioning slot for mounting the linkage screw.

[0014] Based on the above optimization, the mounting shell is installed on the door body at the same installation level as the base using screws.

[0015] Based on the above optimization, the mounting housing is provided with a protective cover for covering the drive motor, reduction clutch, and linkage screw. The protective cover is snapped onto the drive mounting housing, and the protective cover has a clearance groove to facilitate the movement of the push rod.

[0016] The advantages of this utility model are:

[0017] 1) By using the meshing connection between the active and driven teeth, the transmission stability of the linkage group and the linkage transmission group is enhanced. When the drive motor is activated, it drives the linkage group to swing, so that the linkage transmission group automatically folds or unfolds, thereby closing or opening the hinge, realizing the electric opening and closing of the door. It is convenient, reliable and practical.

[0018] 2) The drive unit is assembled on the door body using a mounting shell, which avoids the accumulation of dirt and better protects the drive unit. The drive unit is assembled separately from the hinge, which simplifies the structure, reduces the assembly volume, facilitates disassembly, maintenance and replacement, and extends the service life of the product. It is also suitable for manual or electric operation and has strong applicability. Attached Figure Description

[0025] The present invention will now be further described with reference to the accompanying drawings.

[0026] According to the appendix Figures 1 to 6 As shown, the meshing electric hinge device of this utility model includes a fixed base 1 installed on the cabinet body, a base 2 installed on the door body, and a linkage transmission assembly 3 hinged between the fixed base 1 and the base 2. The door body is equipped with a driving device, which includes a drive motor 4 and a linkage assembly 5. The linkage assembly 5 has a driving tooth 6, and the linkage transmission assembly 3 has a driven tooth 7. The driving tooth 6 and the driven tooth 7 are adapted to mesh and connect. The drive motor 4 is mounted on the door body, and the output shaft of the drive motor 4 is connected to the linkage assembly 5. When the drive motor 4 operates, it drives the linkage assembly 5 to move, causing the driving tooth 6 and the driven tooth 7 to rotate relative to each other. This causes the linkage transmission assembly 3 to unfold or fold, thus driving the base 2 to open and close against the fixed base 1.

[0027] In this way, the transmission stability of the linkage group 5 and the linkage transmission group 3 is enhanced by the meshing connection of the active tooth 6 and the driven tooth 7. When the drive motor 4 is activated, it drives the linkage group to swing, so that the linkage transmission group 3 automatically folds or unfolds, thereby closing or opening the hinge and realizing the electric opening and closing of the door. It is convenient, reliable and practical.

[0028] Reference Figures 1 to 6 As shown in the diagram, further detailed, a reduction clutch 9 is installed between the linkage group 5 and the drive motor 4. The linkage transmission group 3 includes a main beam 31, a secondary beam 32, a first connecting rod 33, and a second connecting rod 34. The connecting ends of the main beam 31 and the secondary beam 32 are respectively hinged to the fixed base 1. The connecting ends of the first connecting rod 33 and the second connecting rod 34 are respectively hinged to the middle and swinging parts of the main beam 31. The swinging end of the secondary beam 32 is hinged to the middle of the first connecting rod 33. The swinging ends of the first connecting rod 33 and the second connecting rod 34 are hinged to the base 2. The driven tooth 7 is integrally formed at the end of the second connecting rod 34 and meshes with the driving tooth 6.

[0029] In actual operation, the main beam 31, the secondary beam 32, the first connecting rod 33, and the second connecting rod 34, driven by the drive motor 4, form an electrically operated four-bar linkage 3 that can be unfolded or folded between the fixed seat 1 and the base 2. This enhances structural stability, improves transmission smoothness, and effectively prevents hinge deformation.

[0030] Furthermore, a limiting rod 8 is provided between the driving tooth 6 and the driven tooth 7 to prevent the linkage assembly 5 from separating from the second connecting rod 34. The two ends of the limiting rod 8 are respectively hinged to the driving tooth 6 and the driven tooth 7. This effectively prevents the driving tooth and the driven tooth from separating, thus enhancing transmission stability.

[0031] Furthermore, the linkage assembly 5 includes a lead screw 51, a sliding block 52, and a push rod 53. The lead screw 51 is equipped with a reduction clutch 9 connected to the drive motor 4. The sliding block 52 is threaded onto the lead screw 51. One end of the push rod 53 is connected to the sliding block 52, and the other end of the push rod 53 is connected to the swinging part of the main beam 31. The active gear 6 is integrally formed on the end of the push rod 53.

[0032] During operation, the drive motor 4 actuates, causing the linkage screw 51 to rotate. This causes the sliding block 52 to move back and forth on the linkage screw 51, and the push rod 53 moves back and forth accordingly. This causes the driving gear 6 to move, simultaneously driving the driven gear 7 to move, thereby linking the second linkage 34 to swing, causing the four-bar linkage assembly 3 to fold or unfold, and the hinge to open and close automatically, achieving electric opening and closing of the door on the cabinet. The linkage transmission assembly 3 and linkage rod assembly 5 using this structure have a simple structure, are easy to operate, enhance transmission stability, and improve the quality of hinge use.

[0033] Reference Figures 1 to 6 As shown in the figure, in further detail, the driving device also includes a mounting shell 10, which has a mounting cavity 101 for mounting the drive motor 4 and the reduction clutch 9 and a positioning slot 102 for rotating the linkage screw 51.

[0034] The mounting shell 10 is installed on the door body at the same mounting level as the base 2 by screws.

[0035] The drive unit is assembled on the door body using the mounting shell 10. The drive unit is assembled separately from the hinge, which is simple in structure, reduces the assembly volume, facilitates disassembly, maintenance and replacement, extends the service life of the product, and is suitable for manual or electric operation, making it highly versatile.

[0036] In addition, the mounting housing 10 is provided with a protective cover 11 for covering the drive motor 4, the reduction clutch 9, and the linkage screw 51. The protective cover 11 is snapped onto the drive mounting housing 10, and the protective cover 11 has a clearance groove to facilitate the movement of the push rod 53.

[0037] The structural fit between the mounting housing 10 and the protective cover 11 prevents the accumulation of dirt, better protects the drive unit, and extends the product's service life.

[0038] The above specific embodiments are only specific implementations with better effects of this utility model. All structures that are the same as or equivalent to the meshing electric hinge device of this utility model are within the protection scope of this utility model.
