Technical Field

[0001] This utility model relates to the field of hinge technology, and in particular to a push rod electric hinge structure. Background Technology

[0002] A hinge is a device that connects two parts, allowing them to rotate and open / close. Hinges are widely used in doors, windows, furniture, and home appliances. With rapid societal development, in addition to basic appliances like rice cookers and induction cookers, more sophisticated appliances such as microwave ovens and ovens have entered homes. Microwave ovens and ovens also rely on hinges to connect their cabinets and doors.

[0003] In the prior art, such as the electric hinge with announcement number CN211666501U, there is a hinge housing; a swing arm, the first end of which is pivotally connected to the hinge housing via a pivot; an inner moving arm, installed inside the hinge housing, connected to the first end of the swing arm; and a motor drive structure for driving the inner moving arm to reciprocate linearly within the hinge housing, thereby causing the swing arm to rotate around the pivot point with the hinge housing. In this invention, the motor drive structure drives the opening and closing of the hinge, resulting in better intelligence and automation. Applied to home appliances such as ovens and microwave ovens, it enables electric opening and closing of the door, providing more convenient operation and bringing convenience to people's lives through smart home technology. Furthermore, the application of electric hinges in home appliances such as ovens and microwave ovens allows for the removal of traditional door handles, controlling opening and closing electrically, reducing manufacturing costs and improving overall neatness and aesthetics.

[0004] The above technical solution has some problems in practical application. Although the technical solution can realize the electric opening of the hinge, the power and support force of the hinge are only lifted by the motor during use, which has the problem of large motor load and is not conducive to the long-term use of the hinge.

[0005] Therefore, it is necessary to invent a push rod electric hinge structure to solve the above problems. Utility Model Content

[0006] The purpose of this invention is to provide a push rod electric hinge structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a push rod electric hinge structure, comprising a housing, a hinge head at one end of the housing, a first connecting pin between one end of the hinge head and the housing, a lever plate and an inner support plate slidably disposed inside the housing, a second connecting pin between one end of the lever plate and the end of the hinge head near the first connecting pin, a third connecting pin between one end of the inner support plate and the end of the hinge head near the first connecting pin, the third connecting pin being disposed between the first and second connecting pins, a movable pin fixedly disposed at one end of the inner support plate, a fixed pin fixedly disposed at the end of the housing away from the first connecting pin, a spring fixedly disposed between the fixed pin and the movable pin, and two sliding grooves penetrating through the middle of the housing, with one end of the movable pin and the lever plate slidably disposed inside the two sliding grooves respectively.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] This utility model provides, for example Figure 1-3 The illustrated push rod electric hinge structure includes an outer shell 1. A hinge head 2 is provided at one end of the inner shell 1. A first connecting pin 3 is provided between one end of the hinge head 2 and the outer shell 1. A lever plate 4 and an inner bracket 6 are slidably provided inside the outer shell 1. A second connecting pin 5 is provided between one end of the lever plate 4 and the end of the hinge head 2 near the first connecting pin 3. A third connecting pin 7 is provided between one end of the inner bracket 6 and the end of the hinge head 2 near the first connecting pin 3. The third connecting pin 7 is located between the first connecting pin 3 and the second connecting pin 5. A movable pin 8 is fixedly provided at one end of the inner bracket 6. A fixed pin 10 is fixedly provided at the end of the inner shell 1 away from the first connecting pin 3. A spring 9 is fixedly provided between the fixed pin 10 and the movable pin 8. The spring 9 applies a pulling force to the hinge head 2 to provide auxiliary support.

[0021] Two sliding grooves 11 are provided through the middle of the outer shell 1. One end of the movable pin 8 and the lever plate 4 are slidably disposed inside the two sliding grooves 11. The sliding grooves 11 are designed as horizontal strip structures. The sliding grooves 11 are used to limit the sliding range of the lever plate 4 and the inner bracket 6 in order to control the final position of the hinge head 2 when it is opened and closed.

[0022] An electric cylinder 12 is fixedly provided at the end of the outer wall of the outer shell 1 away from the first connecting pin 3. The output end of the electric cylinder 12 is rotatably provided with a connecting piece 13 via a pin. The connecting piece 13 is slidably provided inside the outer shell 1, and one end of the connecting piece 13 is rotatably connected to the end of the lever piece 4 away from the hinge head 2 via a pin. A mounting bracket 14 is fixedly provided on the outer wall of the outer shell 1. The electric cylinder 12 is fixedly provided on one side of the mounting bracket 14. The electric cylinder 12 adopts the existing structure in the prior art. It is used to push the lever piece 4 to slide horizontally through the connecting piece 13 to control the opening and closing of the hinge head 2.

[0023] Both ends of the spring 9 are equipped with hooks, and the two hooks are respectively located on the outer middle of the fixed pin 10 and the movable pin 8. The hooks facilitate the installation and replacement of the spring 9.

[0024] Working principle of this utility model:

[0025] When using this device, the outer shell 1 is fixed to the door frame in the hinge application area by bolts and other fasteners, and the hinge head 2 is fixed to the door body in the hinge application area by bolts and other fasteners, so that the outer shell 1 and the hinge head 2 are perpendicular to each other. At this time, the device can realize the connection between the door frame and the door body.

[0026] When the door and door frame are in the closed state, the hinge head 2 and the outer shell 1 are in a perpendicular state. At this time, the second connecting pin 5 is located diagonally above the first connecting pin 3 in the direction close to the outer shell 1. At this time, the spring 9 is in the default compressed state. At this time, the movable pin 8 and the second connecting pin 5 are on the same horizontal line. The spring 9 applies a pulling force to the second connecting pin 5, so that the hinge head 2 is subjected to a pulling force in the direction of the outer shell 1. At this time, the hinge head 2 remains perpendicular to the outer shell 1.

[0027] When the door needs to be opened, the electric cylinder 12 drives the connecting piece 13 to slide horizontally. The connecting piece 13 pushes the hinge head 2 away from the outer shell 1 through the lever piece 4. At this time, the hinge head 2 rotates around the first connecting pin 3 and drives the inner bracket 6 to move through the second connecting pin 5. During this process, the second connecting pin 5 makes a circular motion around the first connecting pin 3. In this state, the tension applied by the spring 9 to the hinge head 2 is canceled by the pushing force of the electric cylinder 12. During this process, the movable pin 8 and the second connecting pin 5 are not on the same horizontal line. When the second connecting pin 5 passes directly above the first connecting pin 3, the second connecting pin 5 moves diagonally upward in the direction away from the outer shell 1. At this time, the movable pin 8 and the second connecting pin 5 slowly return to the same horizontal line. At this time, the tension applied by the spring 9 to the hinge head 2 through the inner bracket 6 acts on the first connecting pin 3, so that the hinge head 2 is tightened after opening. At this time, the hinge head 2 remains horizontal with the outer shell 1.

[0028] During the opening and closing process, the spring 9 always applies a pulling force to the hinge head 2. The hinge head 2 drives the second connecting pin 5 to move during the opening and closing process. When the second connecting pin 5 moves directly above the first connecting pin 3, the spring 9 passes through the center. When the second connecting pin 5 is located on the side of the first connecting pin 3 close to the outer shell 1, the spring 9 directly applies a pulling force to the hinge head 2 from the oblique upper side, causing it to rotate counterclockwise around the first connecting pin 3 and remain perpendicular to the outer shell 1. When the second connecting pin 5 is located on the side of the first connecting pin 3 away from the outer shell 1, the spring 9 applies a pulling force to the hinge head 2 from the oblique lower side, causing it to rotate clockwise around the first connecting pin 3 and remain horizontal to the outer shell 1.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
