Description

TECHNICAL FIELD

[0002] A hinge is a mechanical device used to connect two objects and allow relative rotation between the two objects, such as a rotating connection for a door or a closing object. In order to provide a better experience when closing the door, a damping hinge is used, which can automatically close the door when it is close to the closed position and control the rotation speed when closing the door.

[0047] The technical solutions in some embodiments of the present application will be described clearly and completely below in combination with the drawings in some embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, but not all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0048] The technical solutions of the embodiments of the present application will be described in detail below in combination with the drawings.

[0049] As Figures 1 to 7As shown in the figure, the embodiment is a hinge device for the rotation connection of a closing object such as a glass door, which comprises a first connecting seat 11, a second connecting seat 12 and an elastic reset member 13. The first connecting seat 11 is directly or indirectly provided with a shaft hole 151. The second connecting seat 12 is provided with a pivot joint part 14. The pivot joint part 14 is provided with a pivot joint shaft 141 and a driven surface 142. The pivot joint shaft 141 is matched in the shaft hole 151 to realize the rotation connection of the second connecting seat 12 and the first connecting seat 11.

[0050] In the embodiment, in order to realize the automatic rotation between the second connecting seat 12 and the first connecting seat 11, the first connecting seat 11 is further provided with a sheet-shaped elastic reset member 13. The elastic reset member 13 has at least one free end 131. The driven surface 142 of the pivot joint part 14 is arranged to be able to abut against the free end 131 of the elastic reset member 13. Under the deformation reset force of the elastic reset member 13, the second connecting seat 12 can rotate around the axis of the pivot joint shaft 141 from the open position to the closed position.

[0051] In this way, the function of automatic closing is realized by the sheet-shaped elastic reset member 13. Since the sheet-shaped elastic reset member 13 has the characteristics of small volume and thin thickness, the structure of the hinge device is more simple, the thickness is more thin, which is beneficial to improve the appearance and save the cost of hinge material.

[0052] In the embodiment, the elastic reset member 13 is formed by punching a work hole by a metal material. The elastic reset member 13 is provided with an elastic deformation part near the free end 131. The elastic deformation part includes at least one circular arc segment 132. The side of the elastic reset member 13 away from the elastic deformation part is fixedly installed on the first connecting seat 11. The whole elastic reset member 13 is accommodated in the cavity 113 of the first connecting seat 11. The outer side surface of the elastic reset member 13 located at the elastic deformation part abuts against the driven surface 142 of the pivot joint part 14.

[0053] Understandably, the elastic reset member 13 abuts against the pivot joint part 14, so that the elastic deformation part produces elastic deformation and acts on the pivot joint part 14 with a deformation reset force to make the second connecting seat 12 rotate around the axis of the pivot joint shaft 141 from the open position to the closed position. The circular arc segment 132 is easy to deform. The center line of the circular arc segment 132 can be parallel to the axis of the pivot joint shaft 141 or perpendicular to the axis of the pivot joint shaft 141. In this way, the direction of the deformation of the elastic shape can be controlled by the circular arc segment 132.

[0054] In the embodiment, the driven surface 142 of the pivot joint part 14 is a cam surface. The cam surface is arranged to abut against the free end 131 of the elastic reset member 13 to make the second connecting seat 12 rotate around the axis of the pivot joint shaft 141 from the open position to the closed position.

[0055] Understandably, the cam surface here is based on the axis of the pivot shaft 141, the cam surface keeps parallel with the axis, in order to control the force at different angles of rotation, the cam surface can be regular geometric surface, but also irregular surface.

[0056] In the embodiment, in the closed position, the free end 131 of the elastic return member 13 is in contact with the side of the cam surface close to the closing direction, and the elastic return member 13 applies a force to the cam surface in the first direction. Wherein, in the closed position, the first direction is perpendicular to the axis of the pivot shaft 141, and the first direction is also perpendicular to the plane of the first connecting seat 11 and the second connecting seat 12, and the X direction shown in the figure is the first direction.

[0057] The contact of the free end 131 of the elastic return member 13 with the cam surface is not limited to the manner of the embodiment, as shown in Figures 8 to 10 In other embodiments, the free end 131 of the elastic return member 13 can also be in contact with the front surface of the cam surface in the closed position, and the elastic return member 13 applies a force to the cam surface in the second direction. Wherein, in the closed position, the second direction is perpendicular to the axis of the pivot shaft 141, and the second direction is also parallel to the plane of the first connecting seat 11 and the second connecting seat 12, and the Y direction shown in the figure is the second direction.

[0058] As shown in Figures 11 to 13 In other embodiments, the cam surface can have a positioning abutment surface 143, and the free end 131 of the elastic return member 13 can have a contact plane 133, and in the closed position, the contact plane 133 of the elastic return member 13 is in contact with the positioning abutment surface 143 of the cam surface, and the elastic return member 13 applies a force to the cam surface in the second direction. Wherein, in the closed position, the second direction is perpendicular to the axis of the pivot shaft 141, and the second direction is also parallel to the plane of the first connecting seat 11 and the second connecting seat 12, and the Y direction shown in the figure is the second direction.

[0059] In the embodiment, the second connecting seat 12 is integrally formed with the pivot portion 14 at one end close to the first connecting seat 11, and the pivot portion 14 is integrally formed with two coaxial pivot shafts 141 on both sides. In other embodiments, the pivot shaft 141 can also be a separate component, and the pivot shaft 141 is installed in the shaft mounting hole of the pivot portion 14.

[0060] In this embodiment, the bottom of the shaft hole 151 of the first connecting seat 11 is provided with a spherical contact surface 161, the pivot shaft 141 is arranged in the shaft hole 151, and the end surface of the pivot shaft 141 abuts against the spherical contact surface 161 of the shaft hole 151. In this way, the friction between the pivot shaft 141 and the inside of the shaft hole 151 when rotating is reduced, the rotating function is smoother, and the service durability of the hinge device is improved.

[0061] In this embodiment, the first connecting seat 11 is formed with a chamber 113, the pivot part 14 of the second connecting seat 12 is arranged in the chamber 113, and the pivot joint cannot be seen from the outside, which improves the appearance of the hinge and facilitates maintenance. The first connecting seat 11 is provided with a fixing block 15 arranged on both sides of the chamber 113 of the first connecting seat 11 and fixed by a pressing block 17 and a screw. The fixing block 15 is provided with a shaft hole 151, and a support 16 is arranged in the shaft hole 151. The support 16 is provided with a spherical contact surface 161, the pivot shaft 141 is arranged in the shaft hole 151, and the end surface of the pivot shaft 141 abuts against the spherical contact surface 161. The end surface of the pivot shaft and the spherical contact surface of the support are in mutual engagement. The shaft hole 151 can be a through hole or a blind hole. When it is a through hole, the other end of the through hole can be covered by the first connecting seat 11 after the fixing block 15 is fixed and installed. For example, the support 16 is a sphere; or the support 16 is a column, and one end surface of the support 16 is a spherical contact surface 161.

The second connecting column 121 can be integrally formed on the second connecting seat 12 or fixed and installed on the second connecting seat 12 as a single component. When the hinge device is installed on the glass door, the second connecting column 121 passes through the mounting hole of the glass door, and the second connecting seat 12 and the second clamping plate 122 are fixed by a screw and clamped to the glass door.

[0063] In this embodiment, the first connecting seat 11 is provided with a first connecting column 111, a second screw hole is formed in the end surface of the first connecting column 111, and a first clamping plate 112 is connected to the first connecting column 111 by a screw.
