Description

Technical Field

[0001] This application relates to the field of hinge technology, and more particularly to a damping hinge cup assembly and a buffer hinge. Background Technology

[0002] A hinge is a mechanical device used to connect two solids and allow them to rotate relative to each other. The two ends of the hinge are installed on the door and the cabinet respectively. The ultra-thin hinge arm can rotate relative to the door and the cabinet to open and close the door.

[0003] A hinge typically consists of a hinge cup, a hinge arm, and a chassis. To reduce the impact force generated when the hinge cup and hinge arm are closed, and to reduce the noise when closing, thereby improving the user experience, a damping element is usually installed between the hinge cup and hinge arm. The damping element can achieve a kinetic energy conversion mechanism through elastic deformation.

[0004] However, existing damping components are usually externally mounted, with one end hinged to the hinge cup and the other end hinged to the hinge arm. External damping components increase the size of the hinge, making it difficult to adapt to the needs of compact hinges.

[0005] It should be noted that the above content is not necessarily prior art, nor is it intended to limit the scope of patent protection of this application. Utility Model Content

[0009] A hinge arm, which is hinged to the cup head;

[0010] A pusher, which is slidably disposed within the cup head;

[0011] A damping element is used to provide damping force when the hinge arm rotates relative to the cup head;

[0012] Wherein, the direction in which the hinge arm points toward the cup head is defined as the first direction, and the direction in which the axis of rotation of the hinge arm relative to the cup head points is defined as the second direction, and the first direction is perpendicular to the second direction;

[0013] The damping element is disposed inside the cup head along the second direction, with one end of the damping element abutting against the pusher and the other end abutting against the inner wall of one side of the cup head;

[0014] When the hinge arm rotates toward the cup head, the hinge arm pushes the pusher to slide, and the pusher compresses the damping member.

[0015] Optionally, the pusher is provided with a pusher surface, the shape and size of which match the shape and size of the hinge arm;

[0017] Optionally, it also includes a mounting base configured as a cavity structure, wherein the damping element is at least partially slidably disposed within the mounting base.

[0018] Optionally, the pushing member is further provided with a pressing part, which is inclined and used to directly or indirectly abut against the end of the damping member;

[0019] As the pusher slides toward the damper, the inclined pressing part gradually presses against the damper.

[0020] Optionally, it also includes a reset member, one end of which abuts against the fixed base and the other end of which abuts against the push member.

[0021] Optionally, the fixed base is provided with a limiting part, the corresponding position of the pushing member is provided with a clearance hole, one end of the reset member is connected to the limiting part, and the other end is connected to the clearance hole;

[0027] The embodiments of this application employing the above-described technical solution may have the following advantages:

[0028] This utility model provides a damping hinge cup assembly and a buffer hinge. The buffer hinge includes a damping hinge cup assembly, which includes a cup head, a hinge arm, a pusher, and a damping element. The cup head is used to fix and connect to a door or panel. The hinge arm is hinged to the cup head. The pusher is slidably disposed within the cup head. The damping element provides damping force when the hinge arm rotates relative to the cup head. The direction in which the hinge arm points towards the cup head is defined as a first direction, and the direction in which the axis of rotation of the hinge arm relative to the cup head points is defined as a second direction. The first direction is perpendicular to the second direction. The damping element is disposed within the cup head along the second direction, with one end of the damping element abutting against the pusher and the other end abutting against the inner wall of one side of the cup head. When the hinge arm rotates toward the cup head, the hinge arm pushes the pusher to slide, and the pusher compresses the damping element. As can be seen, by adopting the damping hinge cup assembly and buffer hinge of this application, the damping element is built into the cup head, which effectively reduces the overall volume of the hinge and meets the design requirements of compact hinges. The setting of the pusher can convert the axial rotation of the hinge arm into linear compression of the damping element. When the hinge is closed, the damping element generates progressive resistance within the controllable compression stroke. Its nonlinear deformation characteristics can convert most of the collision kinetic energy into heat dissipation, reduce the collision force generated by the hinge cup and hinge arm when closing, and reduce the noise when closing, thereby improving the user experience.

[0038] Exemplary embodiments according to this application will now be described in more detail with reference to the accompanying drawings. It should be understood that these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein.

[0039] Please refer to the following: Figure 1 and Figure 2This application provides a damping hinge cup assembly and a buffer hinge. The buffer hinge includes a damping hinge cup assembly and a chassis (not shown in the figure). The damping hinge cup assembly is detachably connected to the chassis. The damping hinge cup assembly includes a cup head 1, a hinge arm 2, a pusher 3, and a damping element 5. The cup head 1 is used to fix and connect to a door or panel. The hinge arm 2 is hinged to the cup head 1. The pusher 3 is slidably disposed within the cup head 1. The damping element 5 provides damping force when the hinge arm 2 rotates relative to the cup head 1. The direction in which the hinge arm 2 points towards the cup head 1 is defined as the first direction, i.e. Figure 2 The direction indicated by the X-arrow is defined as the direction of the axis of rotation of hinge arm 2 relative to cup head 1, i.e., Figure 2 The direction indicated by the Y-arrow is perpendicular to the second direction. The damping element 5 is disposed within the cup head 1 along the second direction, with one end of the damping element 5 abutting against the pusher 3 and the other end abutting against the inner wall of one side of the cup head 1. When the hinge arm 2 rotates toward the cup head 1, the hinge arm 2 pushes the pusher 3 to slide, and the pusher 3 compresses the damping element 5. It can be seen that by using the damping hinge cup assembly and buffer hinge of this application, the damping element 5 is built into the cup head 1, which effectively reduces the overall volume of the hinge and meets the design requirements of a compact hinge. The setting of the pusher 3 can convert the axial rotation of the hinge arm 2 into linear compression of the damping element 5. When the hinge is closed, the damping element 5 generates progressive resistance within the controllable compression stroke. Its nonlinear deformation characteristics can convert most of the collision kinetic energy into heat dissipation, reduce the collision force generated by the hinge cup and hinge arm 2 when closing, and reduce the noise when closing, thereby improving the user experience.

[0040] Furthermore, such as Figure 2 As shown, the definition Figure 2 The direction indicated by the Z-arrow is the third direction, and the first direction, the second direction, and the third direction are perpendicular to each other. The pusher 3 is provided with a pusher surface 31, the shape and size of which match the shape and size of the hinge arm 2. Specifically, in this embodiment, the pusher surface 31 is configured as an arc, and the part of the hinge arm 2 that abuts against the pusher surface 31 is also configured as an arc. The pusher surface 31 is provided on the pusher 3 along the first direction, and the hinge arm 2 can rotate around the axis of the second direction. When the hinge arm 2 rotates toward the cup head 1, the hinge arm 2 fits against the pusher surface 31 and pushes the pusher 3 to slide along the first direction in the cup head 1. During the sliding process of the pusher 3, the damping member 5 is compressed.

[0041] More specifically, the pusher 3 is also provided with a squeezing part 32, which is inclined and used to directly or indirectly abut against the end of the damping member 5. The squeezing part 32 is used to abut against the projection of the plane of the end of the damping member 5 along the third direction, forming an angle with the X arrow and the Y arrow. When the pusher 3 slides toward the damping member 5 along the first direction, the inclined squeezing part 32 gradually squeezes the damping member 5, so that the damping member 5 is gradually compressed.

[0042] Furthermore, the damping hinge cup assembly of this embodiment also includes a fixed base 4 and a reset member 7. The fixed base 4 is detachably disposed within the cup body and is configured as a cavity structure. The damping member 5 is at least partially slidably disposed within the fixed base 4. One end of the reset member 7 abuts against the fixed base 4, and the other end abuts against the push member 3, such as... Figure 2 and Figure 3 As shown, the fixed base 4 is provided with a limiting part 42, and the corresponding position of the pushing member 3 is provided with a relief hole 33. Both the limiting part 42 and the relief hole 33 are arranged along the first direction. In this embodiment, the reset member 7 is configured as a spring, one end of which is connected to the limiting part 42 and the other end is connected to the relief hole 33; as Figure 3 As shown, when the hinge arm 2 rotates around the axis of the Y-arrow, the hinge arm 2 abuts against the pushing surface 31, causing the pushing member 3 to move towards the fixed seat 4 in the first direction, and the fixed seat 4 and the pushing member 3 compress the reset member 7; preferably, when the fixed seat 4 and the pushing member 3 move to the limit position, the limiting part 42 is inserted into the relief hole 33; as Figure 2 As shown, the fixed base 4 is provided with a limiting hole 41. The damping member 5 includes a piston rod 51, which is detachably inserted into the limiting hole 41. A slot is opened on the side wall of the limiting hole 41 on the opposite side in the second direction. The damping member 5 is inserted into the cavity of the fixed base 4 through the slot, and one end of the cylinder of the damping member 5 is exposed in the slot. The pressing part 32 slides against the cylinder at the slot. The inclined pressing part 32 gradually presses the damping member 5, causing the damping member 5 to gradually compress. Due to the setting of the limiting hole 41, the piston rod 51 will not... The cylinder of the damping element 5 protrudes from the limiting hole 41 and moves in the second direction. The piston rod 51 is gradually compressed into the cylinder, which provides damping force. The pusher 3 can convert the axial rotation of the hinge arm 2 into linear compression of the damping element 5. When the hinge is closed, the damping element 5 generates progressive resistance within the controllable compression stroke. Its nonlinear deformation characteristics can convert most of the collision kinetic energy into heat dissipation, reduce the collision force generated by the hinge cup and hinge arm 2 when closing, and reduce the noise when closing, thereby improving the user experience.

[0043] As an optional implementation, the damping hinge cup assembly of this embodiment also includes a sleeve 6, which is sleeved on the damping member 5. The pressing part 32 slides against the end of the sleeve 6. When the pushing member 3 moves along the first direction, the inclined pressing part 32 gradually presses the sleeve 6 and the cylinder of the damping member 5 together to move. The sleeve 6 can prevent the damping member 5 from directly contacting the inner cavity of the fixed seat 4, thereby reducing the generated collision force.

[0044] In summary, this application provides a damping hinge cup assembly and a buffer hinge. Using the damping hinge cup assembly and buffer hinge of this application, the damping element 5 is built into the cup head 1, effectively reducing the overall volume of the hinge and adapting to the design requirements of a compact hinge. The pusher 3 can convert the axial rotation of the hinge arm 2 into linear compression of the damping element 5. When the hinge is closed, the damping element 5 generates progressive resistance within a controllable compression stroke. Its nonlinear deformation characteristics can convert most of the collision kinetic energy into heat dissipation, reducing the collision force generated by the hinge cup and hinge arm 2 when closed, and reducing the noise during closure, thereby improving the user experience.
