Abstract
Description
Technical Field
[0001] This utility model relates to the field of hinge technology, specifically an easy-to-install 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 easy-to-install electric hinge device with a simple structure, adopting a split assembly structure, which is easy to assemble and disassemble, convenient for maintenance and replacement, and extends the service life of the product. It can also open and close the door electrically, with smooth transmission, easy to use, and reliable and practical.
[0008] The objective of this invention is achieved as follows: an easily installable 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 linkage transmission assembly is equipped with a drive device that electrically drives the base to open and close on the fixed base. 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 the base. The connecting ends of the first connecting rod and the second connecting rod are respectively hinged to the middle and swinging parts of the main beam. The swinging end of the secondary beam is hinged to the middle of the first connecting rod. The swinging ends of the first and second connecting rods are hinged to the base. The drive device includes a linkage group and a drive motor. The swinging part of the main beam is connected to the output end of the linkage group, and the output shaft of the drive motor is connected to the input end of the linkage group. When the drive motor operates, it drives the linkage group to change from rotational motion to linear forward and backward movement, thereby causing the swinging part of the main beam to swing back and forth while simultaneously causing the base to automatically open and close on the fixed base.
[0009] 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 folded or unfolded between the fixed seat and the base.
[0010] Based on the above optimization, a reduction clutch is installed between the linkage group and the drive motor.
[0011] 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.
[0012] Based on the above optimization, the main beam is provided with a connecting flange for rotatably connecting with the push rod via a connecting shaft, and the connecting flange is integrally formed on the swing end of the main beam.
[0013] Based on the above optimization, the drive device also includes a drive mounting housing for mounting the drive motor and linkage assembly, and the drive mounting housing is installed at the bottom of the door body by screws.
[0014] Based on the above optimization, the drive mounting housing is provided with a snap-fit cavity for mounting the drive motor and the reduction clutch 6.
[0015] Based on the above optimization, the drive mounting housing is provided with a connecting slot for facilitating the rotation of the linkage screw. One end of the linkage screw is rotatably connected to the connecting slot, and the other end of the linkage screw is connected to the output shaft of the reduction clutch.
[0016] Based on the above optimization, the drive mounting housing is provided with a protective cover for covering the drive motor, reduction clutch, and linkage screw, and the protective cover is snapped onto the drive mounting housing.
[0017] The advantages of this utility model are:
[0018] 1) The main beam of the linkage transmission group of this structure is directly connected to the linkage group and the drive motor. When in use, the drive motor is activated, which drives the linkage group, thereby making the linkage transmission group automatically fold or unfold. The electric hinge structure realizes automatic opening and closing of the door, which saves effort, is flexible in use, easy to assemble, smooth in transmission, and is reliable and practical.
[0019] 2) The linkage transmission group and linkage group of this structure can change from rotation to linear forward and backward movement, so as to drive the main beam to swing and make the hinge open and close automatically, so as to achieve the electric opening and closing of the door on the cabinet. The structure is simple, the operation is convenient, the transmission stability is enhanced, and the quality of hinge use is improved.
[0020] 3) The drive unit is installed at the bottom of the door body using a drive mounting shell, and is assembled separately from the hinge base. It adopts a split assembly structure, which is easy to assemble and disassemble, effectively avoids water and dust accumulation in the drive unit, facilitates maintenance and replacement, and extends the service life of the product. Manual or electric door opening and closing can also be selected, making it highly applicable. Attached Figure Description

[0027] The present invention will now be further described with reference to the accompanying drawings.
[0028] According to the appendix Figures 1 to 6As shown, the easy-to-install electric hinge device of this utility model includes a fixed base 1 installed on a cabinet, a base 2 installed on a door, and a linkage transmission group 3 hinged between the fixed base 1 and the base 2. 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 base 2. 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 fixed base 1. The linkage transmission group 3 is equipped with a drive device for electrically opening and closing the base 2 on the fixed base 1. The driving device includes a linkage group 4 and a drive motor 5. The swinging part of the main beam 31 is connected to the output end of the linkage group 4, and the output shaft of the drive motor 5 is connected to the input end of the linkage group 4. When the drive motor 5 is activated, it drives the linkage group 4 to change from rotation to linear forward and backward movement, so as to drive the swinging part of the main beam 31 to swing back and forth while the base 2 automatically opens and closes on the fixed seat 1.
[0029] The main beam 31 of the linkage transmission group 3 of this structure is directly connected to the linkage group 4 and the drive motor 5. When in use, the drive motor 5 is activated, which drives the linkage group, thereby making the linkage transmission group 3 automatically fold or unfold. The electric hinge structure realizes automatic opening and closing of the door, which is labor-saving, flexible in use, easy to assemble, smooth in transmission, reliable and practical.
[0030] Reference Figures 1 to 6 As shown in the figure, to be further detailed, a reduction clutch 6 is installed between the linkage group 4 and the drive motor 5.
[0031] Among them, the main beam 31, the small beam 32, the first connecting rod 33, and the second connecting rod 34 form an electric four-bar linkage 3 that can be folded or unfolded between the fixed seat 1 and the base 2 under the drive of the drive motor 5.
[0032] Furthermore, the linkage assembly 4 includes a linkage screw 41, a sliding block 42, and a push rod 43. The linkage screw 41 is equipped with a reduction clutch 6 connected to the drive motor 5. The sliding block 42 is threadedly connected to the linkage screw 41. One end of the push rod 43 is connected to the sliding block 42, and the other end of the push rod 43 is connected to the swinging part of the main beam 31.
[0033] Furthermore, the main beam 31 is provided with a connecting flange 35 for rotatably connecting to the push rod 43 via a connecting shaft, and the connecting flange 35 is integrally formed on the swing end of the main beam 31.
[0034] During operation, the drive motor 5 actuates, causing the linkage screw 41 to rotate. This causes the sliding block 42 to move back and forth on the linkage screw 41, which in turn causes the push rod 43 to push the main beam 31 to swing back and forth. This causes the four-bar linkage assembly 3 to fold or unfold, and the hinges to open and close automatically, thus achieving electric opening and closing of the door on the cabinet. The linkage transmission assembly 3 and linkage rod assembly 4 using this structure have a simple structure, are easy to operate, enhance transmission stability, and improve the quality of hinge use.
[0035] Reference Figures 1 to 6 As shown in the figure, in further detail, the driving device also includes a driving mounting housing 7 for mounting the driving motor 5 and the linkage group 4. The driving mounting housing 7 is mounted on the bottom of the door body by screws.
[0036] The drive mounting housing 7 is provided with a snap-fit cavity 71 for mounting the drive motor 5 and the reduction clutch 6.
[0037] Furthermore, the drive mounting housing 7 is provided with a connecting slot 72 for facilitating the rotation of the linkage screw 41 and a protective cover 8 for covering the drive motor 5, the reduction clutch 6, and the linkage screw 41. One end of the linkage screw 41 is rotatably connected to the connecting slot 72, and the other end of the linkage screw 41 is connected to the output shaft of the reduction clutch 6; the protective cover 8 is snapped onto the drive mounting housing 7.
[0038] In this way, the drive unit is installed at the bottom of the door body using the drive mounting shell 7, and is assembled separately from the hinge base 2. The split assembly structure makes it easy to assemble and disassemble, convenient for maintenance and replacement, and extends the service life of the product. It can also be used with manual or electric door opening and closing, making it highly versatile.
[0039] The above specific embodiments are only specific implementations of the present utility model with better effects. All structures that are the same as or equivalent to the easy-to-install electric hinge device of the present utility model are within the protection scope of the present utility model.
