[0045] In view of the problem of complex bearing seat structure existing in the existing hinge, the embodiment provides a hinge assembly, which refers to Figures 1-8 The hinge assembly comprises a hinge cup 1, a shell 2, a first connecting member 3, a second connecting member 4, a torsional spring 5, a bearing seat 6, a damper 7 and a base 8.

[0046] The hinge cup 1 is used for fixing on the first component; the bottom of the shell 2 is provided with a mounting groove 21, a first rotating shaft 22 is mounted in the mounting groove 21, the two side walls of the mounting groove 21 are both formed with a limiting protrusion 23, the limiting protrusion 23 is arranged in a spaced manner with the bottom wall of the mounting groove 21; one end of the first connecting member 3 is rotatably connected with the hinge cup 1, the other end of the first connecting member 3 is rotatably connected with the shell 2; one end of the second connecting member 4 is rotatably connected with the hinge cup 1, the other end of the second connecting member 4 is rotatably connected with the shell 2; the torsional spring 5 is sleeved on the first rotating shaft 22, one end of the torsional spring 5 is connected with the shell 2, the other end of the torsional spring 5 is connected with the first connecting member 3 or the second connecting member 4; the two sides of the bearing seat 6 are formed with sliding portions 61, the sliding portions 61 are arranged between the bottom wall of the mounting groove 21 and the limiting protrusion 23 so that the bearing seat 6 can slide in the mounting groove 21, the bearing seat 6 is drivingly connected with the second connecting member 4; the damper 7 is arranged inside the bearing seat 6, when the second connecting member 4 rotates to drive the bearing seat 6 to slide, the bearing seat 6 pushes the piston rod of the damper 7, so that the damper 7 generates a resistance force against the resetting of the torsional spring 5; the base 8 is used for fixing on the second component, the base 8 is detachably connected with the shell 2.

[0047] When the hinge assembly of the embodiment is used, under the cooperation of the first connecting member 3, the second connecting member 4 and the torsional spring 5 and other components, the hinge cup 1 can rotate relative to the shell 2, so that the included angle between the first component and the second component changes; wherein, when the hinge cup 1 rotates relative to the shell 2 to reduce the included angle between the first component and the second component, the second connecting member 4 drives the bearing seat 6 to move, under the action of the sliding portions 61, the bearing seat 6 moves in the front-rear direction, so that the bearing seat 6 pushes the piston rod of the damper 7, the damper 7 generates a resistance force against the resetting of the torsional spring 5, thereby achieving a buffering effect.

[0048] In the application, the limiting protrusions 23 and the bottom wall of the shell 2 cooperate to limit the sliding portions 61 on the two sides of the bearing seat 6, in this way, the sliding portions 61 can correct the bearing seat 6 in the left-right direction and the up-down direction, so that the bearing seat 6 stably slides in the front-rear direction; compared with the existing hinge, the hinge of the application does not need to stamp a flat portion on the top of the bearing seat 6, nor does it need to press a limiting rod on the shell 2, which reduces the processing difficulty of the hinge, improves the yield of the hinge, and reduces the production cost of the hinge.

[0049] In some embodiments, the limiting protrusions 23 are stamping formed on the shell 2; in this way, the limiting protrusions 23 can serve as a reinforcing structure while serving as a limiting structure, so that the tensile and bending resistance of the two side plates of the shell 2 is stronger, on the contrary, under the condition of reducing the wall thickness of the side plates of the shell 2, the reinforcing of the limiting protrusions 23 can also make the tensile and bending resistance of the two side plates of the shell 2 not weaker than that of the existing hinge, that is, through this design, the material consumption of the shell 2 can be reduced, thereby reducing the production cost of the shell 2.

[0050] In some embodiments, the limiting protrusion 23 is in a strip structure extending in the front-rear direction; in this way, the contact area of the limiting protrusion 23 and the sliding portion 61 can be increased, and the stability of the bearing seat 6 sliding in the mounting groove 21 can be improved. The limiting protrusion 23 can also be in other structures, such as a plurality of protrusions distributed at intervals, which are not limited herein.

[0051] Further, the side wall of the shell 2 is provided with a stop portion 24 on the side of the limiting protrusion 23 away from the hinge cup 1. The design of the stop portion 24 not only further improves the tensile and bending resistance of the shell 2, but also limits the bearing seat 6 when the bearing seat 6 is installed into the shell 2, preventing the bearing seat 6 from being installed too deeply to interfere with other components of the shell 2, and allowing the second connecting member 4 to be better connected with the bearing seat 6, reducing the installation difficulty of the bearing seat 6 and improving the production efficiency of the hinge.

[0052] In some embodiments, the bearing seat 6 is provided with an abutting portion 62 on both sides, and the second connecting member 4 is provided with a buckling arm 41; when the second connecting member 4 rotates forward, the buckling arm 41 contacts the abutting portion 62 and drives the bearing seat 6 to move, at this time, the rear side plate of the bearing seat 6 pushes the piston rod of the damper 7, and the other end of the damper 7 abuts against the torsional spring 5 or other stop portion 24, so as to compress the piston rod, and then generate a resistance against the resetting of the torsional spring 5, and when the second connecting member 4 rotates reversely, the buckling arm removes the pushing force on the abutting portion 62, and the piston rod of the damper 7 is automatically reset under the action of the spring in the damper 7, so as to drive the bearing seat 6 to move. Here, the forward and reverse directions are only the rotation states of the second connecting member 4, when the forward direction is clockwise, the reverse direction is counterclockwise, and when the forward direction is counterclockwise, the reverse direction is clockwise.

[0053] In some embodiments, the limiting protrusion 23 is arranged on the side of the abutting portion 62 away from the hinge cup 1; in this way, when the bearing seat 6 is installed into the shell 2, the limiting protrusion 23 can cooperate with the abutting portion 62 to limit the bearing seat 6, preventing the bearing seat 6 from being installed too deeply to interfere with other components of the shell 2, and then reducing the installation difficulty of the bearing seat 6 and improving the production efficiency of the hinge.

[0054] In some embodiments, the first connecting member 3 and the second connecting member 4 are both provided with a reinforcing portion; through the arrangement of the reinforcing portion, the strength of the first connecting member 3 and the second connecting member 4 can be improved, and the tensile and bending resistance can be improved, so as to prolong the service life of the hinge and improve the economic benefit. The reinforcing portion can be a protruding structure stamped on the first connecting member 3 or the second connecting member 4.

[0055] In some embodiments, the base 8 has a first engaging position 81 and a second engaging position 82; the hinge assembly also includes a clamping member 25 and an elastic member 26; the clamping member 25 is pivotally connected to the housing 2; the elastic member 26 is disposed inside the housing 2, one end of the elastic member 26 is connected to the housing 2, and the other end of the elastic member 26 is connected to the clamping member 25, the clamping member 25 has a clamping portion 251 that engages with the first engaging position 81, and the housing 2 has a hook portion 27 that engages with the second engaging position 82. It is understood that the elastic member 26 can be a spring, a tension spring, or a compression spring, etc., and the clamping member 25 is pressed by an external force to cause the clamping member 25 to rotate relative to the housing 2, while the elastic member 26 deforms under the force. When the outer shell 2 is fixedly installed on the first component and the base 8 is fixed on the second component, the pressing part 251 of the pressing member 25 is aligned with the first fastening position 81 and the hook part 27 is aligned with the second fastening position 82. When an external force is applied to the outer shell 2, the pressing part 251 drives the elastic member 26 to compress, causing the pressing part 251 to undergo a slight displacement so that the hook part 27 and the second fastening position 82 are fastened together. When the first fastening position 81 slides past the pressing part 251, the compressed elastic member 26 drives the pressing part 251 to reset and fasten to the first fastening position 81, so that the outer shell 2 is fastened to the base 8 by means of a snap. When the outer shell 2 needs to be removed from the base 8, press the clamping member 25 to stretch the elastic member 26, drive the clamping part 251 to make a slight displacement, release the locking effect between the clamping part 251 and the second fastening position 82, and then drive the outer shell 2 to move relative to the base 8, further releasing the locking effect between the hook part 27 and the first fastening position 81, thereby separating the outer shell 2 from the base 8, and then separating the outer shell 2 from the base 8.

[0056] In some embodiments, the base 8 is provided with reinforcing portions at positions corresponding to the first engaging position 81 and the second engaging position 82. This enhances the strength of the base 8 at the first engaging position 81 and the second engaging position 82, thereby improving the connection stability between the outer shell 2 and the base 8.

[0057] In some embodiments, the bottom of the base 8 is provided with at least two pre-positioning portions 83 for penetrating into the second component. When the base 8 is installed, the installer can first apply a certain pressure to the base 8, so that the pre-positioning portions 83 penetrate into the second component, thereby pre-positioning the base 8. In this way, during the locking process of the base 8, the risk of the base 8 deviating along the installation surface of the second component is greatly reduced, ensuring that the base 8 can be locked at the preset position of the second component, and improving the installation quality of the hinge. In addition, after the pre-positioning portions 83 penetrate into the second component, the installer only needs to apply a small pressure to the base 8 to fix the base 8 on the second component, so that the installation of the base 8 is more labor-saving, and the installation difficulty of the base 8 is reduced. Preferably, the cross section of the pre-positioning portion 83 is triangular, so that the pre-positioning portion 83 can easily penetrate into the second component. Of course, the pre-positioning portion 83 can also have other structures, which are not limited here.

[0058] In some embodiments, the base 8 is provided with an installation hole 84, and when the base 8 is installed, the screw penetrates through the installation hole 84 and is locked into the second component, so that the base 8 and the second component are fixedly connected. The bottom of the base 8 is provided with a surrounding edge 85 outside the installation hole 84, which can improve the contact area between the screw and the base 8, thereby improving the connection firmness of the base 8 and the second component. Further, the pre-positioning portion 83 is arranged at the bottom of the surrounding edge 85, so that after the screw is locked into the second component, the head of the screw will apply pressure to the surrounding edge 85, and the pre-positioning portion 83 will be further inserted into the second component, so that the connection firmness between the base 8 and the second component is further improved.

[0059] The above only describes the preferred embodiments of the present application, and the structure is not limited to the shapes listed above. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
