Description

Technical Field

[0001] The invention relates to an opening and closing optimization structure of an embedded hinge. Background Art

[0002] Chinese patent document number CN211287185U disclosed on August 18, 2020 an adjustable embedded hinge structure with a damper, which includes a hinge cup and a bracket that are hinged to each other through a connecting arm assembly, and the connecting arm assembly includes an outer connecting arm and an inner connecting arm, and one end of the outer connecting arm and the inner connecting arm are respectively hinged to the hinge cup, and the other end is respectively hinged to the bracket; a damper is also provided on the bracket, and the damper is located between the outer connecting arm and the inner connecting arm; the outer connecting arm or the inner connecting arm acts at least when the hinge cup is hinged closed relative to the bracket and drives the damper to generate a damping force to achieve a damped hinged closure of the hinge cup relative to the bracket. The damper of the above structure interacts with the outer connecting arm. At the same time, in order to increase the bearing weight of the hinge, a first elastic member and a second elastic member are specially provided. The first elastic member interacts with the outer connecting arm, and the second elastic member interacts with the inner connecting arm. The provision of the first elastic member and the second elastic member not only increases the production cost, but also generates relatively little elastic force when the two members act on the outer connecting arm and the inner connecting arm respectively, and cannot truly achieve the purpose of increasing the bearing weight of the hinge. In addition, the assembly process of the damper, the first elastic member and the second elastic member is also quite complicated. Therefore, further improvement is necessary. Summary of the invention

[0003] The purpose of the present invention is to provide an optimized opening and closing structure of an embedded hinge to overcome the shortcomings of the prior art.

[0004] An optimized opening and closing structure of an embedded hinge designed for this purpose comprises a hinge cup and a bracket which are hinged to each other for opening and closing via a connecting arm assembly, and is characterized in that an elastic part and a damper are arranged on the bracket; the connecting arm assembly comprises at least an outer connecting arm, which is hinged to the hinge cup and the bracket respectively, and an elastic acting part and a transition part are also arranged on the outer connecting arm.

[0005] When the hinge cup is hinged and opened and closed to a certain position relative to the bracket, the outer connecting arm interacts with the elastic member through the elastic action part to realize the elastic hinged opening and closing between the hinge cup and the bracket.

[0006] When the hinge cup is hinged and closed to a certain position relative to the bracket, the outer connecting arm acts through the adapter and drives the damper to generate a damping force, so as to realize the damping hinged closure between the hinge cup and the bracket.

[0007] One end of the outer connecting arm is hinged to the hinge cup, and the other end is hinged to the bracket, and an elastic action part and a connecting part are extended therefrom; the outer connecting arm interacts with the elastic part through the elastic action part, and is connected with the adapter through the connecting part.

[0008] The elastic action portion and the connecting portion are independent of each other, and the two extend integrally on the outer connecting arm in different directions.

[0009] A linear groove is provided on the bracket; one end of the adapter is rotatably connected to the outer connecting arm, and the other end is cooperatively connected to the damper; the adapter and the damper are guided to slide on the linear groove when the hinge cup is hinged and opened and closed relative to the bracket.

[0010] A sliding part is arranged between the adapter and the damper, and the two slide on the linear groove guided by the sliding part.

[0011] The damper is an automatic reset damper or a non-automatic reset damper and is positioned on the bracket. The direction in which the damper is set is substantially parallel to the direction in which the linear slot is set.

[0012] The damper comprises at least a cylinder body and a piston rod; one end of the cylinder body is positioned on the bracket, one end of the piston rod is cooperatively connected with the end of the adapter, and the other end of the piston rod slides at the other end of the cylinder body through the drive and extension of the adapter, or one end of the piston rod is positioned on the bracket, one end of the cylinder body is cooperatively connected with the end of the adapter, and the other end of the cylinder body slides at the other end of the piston rod through the drive and extension of the adapter.

[0013] The damper is positioned and acts on the bracket, and it at least includes a cylinder body and a piston rod; one end of the adapter is rotatably connected to the external connecting arm, and its rotation position is point A, and the other end of the adapter is cooperatively connected to one end of the piston rod or the cylinder body, and its rotation position is point B; the adapter and the piston rod or the cylinder body are guided to slide on the linear groove when the hinge cup is hinged and opened and closed relative to the bracket.

[0014] An angle X is formed between the point A, the point B and the axis of the linear groove, and the angle X is always an acute angle when the hinge cup is hinged and closed relative to the bracket.

[0015] The connecting arm assembly also includes an inner connecting arm, one end of which is hinged to the hinge cup, and the other end is hinged to the bracket; the outer connecting arm is hinged to the hinge cup at one end, and the other end is hinged to the bracket, and interacts with the elastic part and the damper through the elastic action part, the adapter, and the elastic part respectively; the hinge cup is opened and closed on the bracket through the coordinated elastic hinge of the outer connecting arm, the inner connecting arm, and the elastic part, and is closed on the bracket through the coordinated damping hinge of the outer connecting arm, the adapter, and the damper when the hinge is closed to a certain position.

[0016] The present invention improves the above structure, and an elastic member and a damper are arranged on the bracket, and an elastic action part and an adapter are arranged on the outer connecting arm. During assembly and use, the outer connecting arm interacts with the elastic member and the damper through the elastic action part and the adapter, that is, the elastic action force generated by the elastic member and the damping force generated by the damper can be applied on the same outer connecting arm, so the generation of the elastic action force and the damping force is more direct, so that the hinge cup can be hinged and opened and closed and damped and closed on the bracket smoothly, smoothly and without collision, thereby improving the user experience; and, due to the direct action of the force, the hinge can withstand a larger load-bearing weight and can also generate better damping buffering force when closed, thereby allowing the hinge to be assembled and used with a door body with a larger size and weight, thereby improving the scope of use; and, since the outer connecting arm is used to directly interact with the elastic member and the damper, the overall structure of the hinge can be simplified, which not only improves the compactness of the connection between the components and reduces the assembly size, but also reduces the production cost and simplifies the assembly process.

[0017] In general, it has the characteristics of simple and reasonable structure, reliable performance, low manufacturing cost, easy production and implementation, stable and smooth opening and closing, no collision, safety and reliability, and strong practicality.

[0022] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] See also Figure 1-Figure 6 The opening and closing optimized structure of the embedded hinge includes a hinge cup 1 and a bracket 2 which are hinged to each other through a connecting arm assembly, and an elastic member 3 and a damper are arranged on the bracket 2; the connecting arm assembly includes at least an outer connecting arm 4, which is hinged to the hinge cup 1 and the bracket 2 respectively, and an elastic action part 5 and a transition member 6 are also arranged on it.

[0024] When the hinge cup 1 is hingedly opened and closed to a certain position relative to the bracket 2 , the outer connecting arm 4 interacts with the elastic member 3 through the elastic action portion 5 to realize the elastic hinged opening and closing between the hinge cup 1 and the bracket 2 .

[0025] When the hinge cup 1 is hinged and closed to a certain position relative to the bracket 2 , the outer connecting arm 4 acts through the adapter 6 and drives the damper to generate a damping force, so as to realize the damped hinged closure between the hinge cup 1 and the bracket 2 .

[0026] During assembly and use, the outer connecting arm 4 interacts with the elastic member 3 and the damper through the elastic action part 5 and the adapter 6 respectively, that is, the elastic force generated by the elastic member 3 and the damping force generated by the damper can be applied to the same outer connecting arm 4, so the generation of the elastic force and the damping force is more direct, so that the hinge cup 1 can be hinged open and closed and damped closed on the bracket 2 steadily, smoothly and without collision, thereby improving the user experience.

[0027] Moreover, due to the direct effect of force, the hinge can withstand a greater load and produce better damping force when closed, so that the hinge can be assembled and used with doors that are larger in size and weight, thereby increasing its scope of use.

[0028] During operation, when the hinge cup 1 is hinged to a certain position relative to the bracket 2, the outer connecting arm 4 will interact with the elastic member 3 through the elastic action portion 5, so that the hinge cup 1 can be elastically hinged to open and close relative to the bracket 2, allowing the user to conveniently and quickly open and / or close the hinge cup 1. When the hinge cup 1 is hinged to a certain position relative to the bracket 2, the outer connecting arm 4 will interact with the damper through the adapter 6, so that the hinge cup 1 can be damped and hinged to close relative to the bracket 2, avoiding collision between the hinge cup 1 and the bracket 2 when closing, thereby extending the service life of the hinge, improving the user experience, and making the hinge stable, smooth, and silent when opening and closing.

[0029] Specifically, one end of the external connecting arm 4 is hinged to the hinge cup 1, and the other end is hinged to the bracket 2, and an elastic action part 5 and a connecting part 7 are extended therefrom; the external connecting arm 4 interacts with the elastic part 3 through the elastic action part 5, and is connected with the adapter 6 through the connecting part 7.

[0030] The elastic acting portion 5 and the connecting portion 7 are independent of each other, and the two extend integrally in different directions on the outer connecting arm 4. Since the elastic acting portion 5 and the connecting portion 7 extend integrally on the outer connecting arm 4, the outer connecting arm 4 can directly interact with the elastic member 3 and the damper, thereby simplifying the overall structure of the hinge, not only improving the compactness of the connection between the components and reducing the assembly size, but also reducing the production cost and simplifying the assembly process.

[0031] A linear groove 8 is provided on the bracket 2; one end of the adapter 6 is rotatably connected to the outer connecting arm 4, and the other end is cooperatively connected to the damper; the adapter 6 and the damper are guided to slide on the linear groove 8 when the hinge cup 1 is hinged and opened and closed relative to the bracket 2.

[0032] A sliding portion 9 is provided between the adapter 6 and the damper, and the two slide on the linear groove 8 guided by the sliding portion 9 .

[0033] By utilizing the cooperation between the linear groove 8 and the sliding part 9, the adapter 6 and the damper can perform guided linear sliding at a specified position, which not only further improves the connection compactness between the components, but also improves the mutual assembly stability, making the damping force generated by the damper more stable and reasonable.

[0034] The damper of this structure is an automatic reset damper, and may also be a non-automatic reset damper, which is positioned on the bracket 2, and the direction in which the damper is set is substantially parallel to the direction in which the linear slot 8 is set.

[0035] Furthermore, the damper includes at least a cylinder body 10 and a piston rod 11; one end of the cylinder body 10 is positioned on the bracket 2, one end of the piston rod 11 is cooperatively connected with the end of the adapter 6, and the other end of the piston rod 11 slides at the other end of the cylinder body 10 through the drive and extension of the adapter 6, or one end of the piston rod 11 is positioned on the bracket 2, one end of the cylinder body 10 is cooperatively connected with the end of the adapter 6, and the other end of the cylinder body 10 slides at the other end of the piston rod 11 through the drive and extension of the adapter 6.

[0036] Specifically, the cylinder body 10 of this embodiment is laterally arranged on the bracket 2, and one end thereof is positioned on the bracket 2. The lateral setting direction of the cylinder body 10 is basically parallel to the setting direction of the linear groove 8; one end of the adapter 6 is rotatably connected to the outer connecting arm 4, and its rotation position is point A, and the other end of the adapter 6 is cooperatively connected to one end of the piston rod 11, and its rotation position is point B. The other end of the piston rod 11 is driven by the adapter 6 to slide telescopically at the other end of the cylinder body 10.

[0037] The adapter 6 and the piston rod 11 are guided to slide on the linear groove 8 when the hinge cup 1 is hinged to open and close relative to the bracket 2.

[0038] An angle X is formed between point A, point B and the axis of the linear groove 8 , and the angle X is always an acute angle when the hinge cup 1 is hinged and closed relative to the bracket 2 .

[0039] Since the assembly angle between the adapter 6 and the damper is always an acute angle when the hinge is opened and closed, the elastic force generated by the elastic member 3 during operation can be partially decomposed, thereby reducing the force applied by the elastic force on the damper, avoiding damage to the damper due to excessive force, and increasing the service life of the damper.

[0040] The connecting arm assembly also includes an inner connecting arm 12, one end of which is hinged to the hinge cup 1, and the other end is hinged to the bracket 2; the outer connecting arm 4 is hinged to the hinge cup 1 at one end, and hinged to the bracket 2 at the other end, and interacts with the elastic member 3 and the damper through the elastic action part 5 and the adapter 6 respectively; the hinge cup 1 is opened and closed on the bracket 2 through the coordinated elastic hinge of the outer connecting arm 4, the inner connecting arm 12, and the elastic member 3, and is closed on the bracket 2 through the coordinated damping hinge of the outer connecting arm 4, the adapter 6, and the damper when the hinge is closed to a certain position.

Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
