Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a simplified 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 electric hinges use transmission components with complex structures and poor transmission stability. In addition, the combined structure of the drive unit and force transmission device results in a large volume, 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 electric 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.

[0007] 3) Existing electric hinges control the opening and closing of the door through electric control. However, when there is a power outage or when manual operation is required, the door is difficult to operate due to the large load on the door, which reduces the effectiveness of use.

The driving component includes a linkage rod group and a drive motor installed in the door housing and the mounting housing. One end of the linkage rod group is connected to the output shaft of the drive motor, and the other end of the linkage rod group is pushed and pulled connected to the swing end of the main beam.

[0010] Based on the above optimization, the main beam is provided with a closing power source that assists in closing the door when it is manually operated. The closing power source includes an assisting elastic element and an assisting roller. One elastic end of the assisting elastic element is fixedly connected to the main beam, and the other elastic end of the assisting elastic element acts elastically on a second connecting rod through the assisting roller. The connecting end of the second connecting rod is equipped with a cam for sliding connection with the assisting roller. The connecting end of the first connecting rod is provided with a connecting flange that contacts the other elastic end of the assisting elastic element when the door is opened.

[0011] Based on the above optimization, the main beam is provided with a limiting guide groove for limiting the movement of the assist roller, and the assist roller is equipped with a positioning pin for rotatably connecting to the swing end of the main beam. The positioning pin is slidably connected to the limiting guide groove as the main beam swings.

[0012] Based on the above optimization, one end of the base is bent to form a mounting block, and the mounting block is fitted with mounting screws for fixing to the door body.

[0013] Based on the above optimization, the linkage assembly includes a connecting rod, a transmission screw, and a sliding block. The transmission screw is rotatably connected inside the housing, and its input end is connected to the output shaft of the drive motor.

One end of the connecting rod is positioned and connected to the sliding block, and the other end of the connecting rod is positioned and connected to the swing end of the beam via a connecting shaft.

[0014] Based on the above optimization, the swing end of the beam is integrally formed with a positioning protrusion, and the positioning protrusion is equipped with a connecting shaft that is positioned and connected to the connecting rod.

[0015] Based on the above optimization, a clutch is installed at the output end of the drive motor, and the output end of the clutch is connected to the transmission screw.

[0016] Based on the above optimization, the housing is embedded in the door body and fixed to the door body by screws. The housing is provided with a protective cover, which is fastened to the housing and forms a protective cavity with the housing for the assembly of the linkage assembly.

[0017] The advantages of this utility model are:

[0018] 1) The linkage transmission group formed by the combination of the main beam, the secondary beam, the first link, and the second link has a simple structure.

[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 simplified electric hinge device of this utility model includes a fixed base 1 installed on the frame, a base 2 installed on the door body, and a linkage transmission group hinged between the fixed base 1 and the base 2. The linkage transmission group is connected to a driving component for automatically opening and closing the base 2 on the fixed base 1. The linkage transmission group includes a main beam 3, a secondary beam 4, a first connecting rod 5, and a second connecting rod 6. The positioning ends of the main beam 3 and the secondary beam 4 are respectively hinged to the fixed base 1, and the swing ends of the main beam 3 and the secondary beam 4 are respectively hinged to the connecting end of the second connecting rod 6. The connecting end of the first connecting rod 5 is hinged to the middle of the secondary beam 4, and the swing ends of the first connecting rod 5 and the second connecting rod 6 are respectively hinged to the base 2. The driving component includes a linkage rod group and a drive motor 7 installed in the door body housing 15 and the mounting housing 15. One end of the linkage rod group is connected to the output shaft of the drive motor 7, and the other end of the linkage rod group is pushed-pull connected to the swing end of the main beam 3.

[0029] The linkage transmission group formed by the main beam 3, the secondary beam 4, the first connecting rod 5, and the second connecting rod 6 has a simple structure. It adopts a direct linkage method between the main beam 3 and the linkage group of the driving component, which changes the rotation to linear movement, thereby driving the main beam 3 to swing and realize the electric opening and closing of the door. It is easy to assemble, has strong transmission stability, and is reliable and practical.

[0030] Reference Figures 1 to 6 As shown in the diagram, further detailed, the linkage assembly includes a connecting rod 11, a transmission screw 12, and a sliding block 13. The transmission screw 12 is rotatably connected within the housing 15, and its input end is connected to the output shaft of the drive motor 7. The sliding block 13 is threaded onto the transmission screw 12, allowing it to move back and forth relative to the housing 15 as the transmission screw 12 rotates. One end of the connecting rod 11 is positioned and connected to the sliding block 13, and the other end of the connecting rod 11 is positioned and connected to the swing end of the beam 3 via a connecting shaft 33.

[0031] Furthermore, a clutch 14 is installed at the output end of the drive motor 7, and the output end of the clutch 14 is connected to the transmission screw 12.

[0032] In addition, the swing end of the main beam 3 is integrally formed with a positioning protrusion 32, and the positioning protrusion 32 is equipped with a connecting shaft 33 that is positioned and connected to the connecting rod 11.

[0033] During operation, the drive motor 7 actuates, the clutch 14 engages, driving the transmission screw 12 to rotate. Simultaneously, the sliding block 13 moves back and forth on the transmission screw 12, causing the connecting rod 11 to swing back and forth in conjunction with the main beam 3. This causes the linkage transmission assembly to fold or unfold, and the hinges to open and close automatically, achieving electric opening and closing of the door on the cabinet. The linkage transmission assembly and linkage rod assembly using this structure are simple in structure, easy to operate, enhance transmission stability, and improve the quality of hinge use.

[0034] Reference Figures 1 to 6 As shown in the figure, in a more detailed manner, one end of the base 2 is bent to form a mounting block 21, and the mounting block 21 is fitted with mounting screws for fixing to the door body.

[0035] Furthermore, the housing 15 is embedded in the door body and fixed to the door body by screws. The housing 15 is provided with a protective cover 16, which is snapped onto the housing 15 and forms a protective cavity with the housing 15 for the assembly of the linkage assembly.

[0036] The base 2 and the shell 15 of this structure are assembled separately, which is easy to assemble and disassemble, effectively avoids water and dust accumulation in the drive device, facilitates maintenance and replacement, extends the service life of the product, and can be selected as manual or electric opening and closing door, making it highly applicable.

[0037] Reference Figures 1 to 6 As shown in the diagram, further detailed, the main beam 3 is equipped with a closing power source that provides manual assistance in closing the door. This closing power source includes an assisting elastic element 8 and an assisting roller 9. One elastic end of the assisting elastic element 8 is fixedly connected to the main beam 3, and the other elastic end of the assisting elastic element 8 acts elastically on the second connecting rod 6 via the assisting roller 9. The connecting end of the second connecting rod 6 is equipped with a cam 10 for sliding connection with the assisting roller 9, and the connecting end of the first connecting rod 5 is provided with a connecting flange 51 that contacts the other elastic end of the assisting elastic element 8 when the door is opened.

[0038] That is, in the event of a power outage or when manual operation is required, the clutch 14 disconnects from the drive motor 7. When the door is closed to a certain angle, the assist roller 9 contacts the cam 10, and the elasticity of the assist elastic element 8 acts on the assist roller 9, causing the assist roller 9 to roll and connect with the cam 10. This causes the linkage beam 3, the first connecting rod 5, and the second connecting rod 6 to automatically swing towards the fixed seat and retract, thereby realizing the automatic closing of the door in the event of a power outage or when manual operation is required. It also provides closing assistance to ensure that the door is tightly connected to the cabinet, preventing accidental opening and ensuring the quality of product use.

[0039] During this period, the main beam 3 is provided with a limiting guide groove 31 for limiting the movement of the assist roller 9. The assist roller 9 is equipped with a positioning pin 91 for rotating connection to the swing end of the main beam 3. The positioning pin 91 slides in connection with the limiting guide groove 31 as the main beam 3 swings.

[0040] By utilizing the structural cooperation between the limiting guide groove 31 and the positioning pin 91, the transmission stability is enhanced and the buffering effect of the product is guaranteed.

[0041] 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 simplified electric hinge device of the present utility model are within the protection scope of the present utility model.
