The closing action of the hinge is shown in connection with fig. 1, 3, 12 and 13:
in this embodiment, when the first fixing member 10 rotates around one end of the first connecting member 300 in the closing direction and the preset angle is smaller than 30 °, the first fixing member 10 drives the second end of the second connecting member 320 to rotate around the third end of the second connecting member 320 in the first direction, the second end of the second connecting member 320 rotates around the third end of the second connecting member 320 in the second direction, and the second boss 326 is not abutted against the sliding seat 400.
When the first fixing member 10 rotates around one end of the first connecting member 300 in the closing direction and the predetermined angle is about 30 °, the torsion force of the first elastic member 310 drives the second end of the second connecting member 320 to continue to rotate around the third end of the second connecting member 320 in the first direction through the first protrusion 325, and the second end of the second connecting member 320 continues to rotate around the third end of the second connecting member 320 in the second direction, so that the second protrusion 326 abuts against the second protrusion 404 of the sliding seat 400.
When the hinge continues to rotate in the closing direction, the second protrusion 326 abuts against the second protrusion 404 of the sliding base 400, and pushes the sliding base 400 to slide in the inner groove 203 (see fig. 5) toward one end of the second fixing member 20, and at the same time, one end face of the cap 414 abutting against the first elastic member 310 is used as a support.
The sliding of the sliding seat 400 causes the spring 413 (see fig. 10) to be compressed, the spring 413 generates elastic force due to compression, and the elastic force is transferred to the sliding seat 400 through the bottom surface of the shell 412, so that the sliding seat 400 receives buffering resistance exerted by the spring 413 to slow down the sliding speed of the sliding seat 400; meanwhile, the buffering resistance for slowing down the sliding speed of the slider 400 slows down the rotation speed of the first fixing member 10 through the first coupling member 300, the second coupling member 320, and the first elastic member 310.
In the above-mentioned hinge opening motion, in this embodiment, when the first fixing member 10 rotates around one end of the first connecting member 300 in the opening direction and the preset angle is about 30 °, the second end of the second connecting member 320 rotates around the third end of the second connecting member 320 in the third direction, the second end of the second connecting member 320 rotates around the third end of the second connecting member 320 in the fourth direction, the second boss 326 is out of contact with the second boss 404 of the sliding seat 400, the spring 413 is stretched under the action of the elastic force, and pushes the housing 412 out, and pushes the sliding seat 400 to slide in the inner slot 203 toward the other end of the second fixing member 20. When the first fixing member 10 is completely opened, the hinge returns to the state before the closing operation.
Embodiment two:
the present embodiment is different from the first embodiment in the second connector 320 and the slider 400.
Referring to fig. 14 and 15, there are two first protruding columns 325, and two first protruding columns 325 are detachably connected to the second connector 320.
The second connector 320 further comprises a mounting member 334, a fixing plate 331 and a clamping block 332; the clamping block 332 is fixedly arranged on the seventh side surface of the fixing plate 331. One of the first bosses 325 is located at one end of the sixth side of the fixing plate 331 and the other first boss 324 is located at the other end of the sixth side of the fixing plate 331. The two first protruding columns 325 are provided with first through holes 333 arranged coaxially.
The second connector 320 further includes a connection plate 327, where the connection plate 327 connects the fifth side wall 321 and the sixth side wall 323 at a ninth position of the third end. The connecting plate 327 is provided with a clamping groove 328 which is matched with the clamping block 332 in a clamping way.
In this embodiment, the eighth positions of the third ends of the fifth sidewall 321 and the sixth sidewall 323 are respectively provided with a second through hole 329 coaxially disposed.
When the first protruding columns 325 are installed, the clamping blocks 332 are in clamping fit with the clamping grooves 328, and the installation pieces 334 penetrate through the second through holes 329 of the fifth side wall 321 and the sixth side wall 323 and the first through holes 333 of the two first protruding columns 325, so that the two first protruding columns 325 are fixedly installed on the second connecting piece 320.
In this embodiment, the two first protrusions 325 are plastic first protrusions; and the mounting member 334, the fixing plate 331 and the clamping block 332 may be made of plastic. In the process of opening and closing the hinge, the first protruding pillar 325 is always abutted against the first elastic member 310, and the wear resistance of the first protruding pillar 325 is better because the first protruding pillar 325 is a plastic first protruding pillar.
As shown in fig. 14 and 16, the slider 400 is surrounded by a first side 402, a second side, a ninth side 406, a first side 407, and a second side. The first side 402 is disposed opposite the second side, and the first side 407 is disposed opposite the second side. In this embodiment, the accommodating cavity 401 may be configured as a "U" cavity. The damping member 410 is accommodated in the accommodating chamber 401, and an outer circumferential surface of the damping member 410 abuts against the bottom plate 200.
Referring to fig. 14, 17 and 18, when the hinge is installed, one end face of the cap 414 of the damping member 410 abuts against the first elastic member 310, and the center of the end face abuts against the first elastic member 310. The center of one of the end surfaces of the cap head 414 abuts against the first elastic member 310, so that the piston rod 411 is not easily separated from contact with the first elastic member 310.
The embodiment of the invention also provides a household device, which comprises a movable assembly, a fixed assembly and the hinge according to the embodiment, wherein the first fixing piece 10 is arranged on the movable assembly, and the second fixing piece 20 is arranged on the fixed assembly; when the movable assembly rotates around the first connecting member 300 to a predetermined angle, the second protrusion 326 at the second end of the second connecting member 320 is slidably connected with the second protrusion 404 of the sliding seat 400, so that the buffering device 40 generates a buffering effect and slows down the rotation speed of the movable assembly.
When the hinge rotates around one end of the first connecting piece 300 to a preset angle through the first fixing piece 10, the second convex column 326 on the second end of the second connecting piece 320 is slidably connected with the sliding seat 400, so that the buffer device 40 generates a buffer effect, thereby slowing down the rotation speed of the hinge, enabling the movable assembly to be slowly and softly closed, and eliminating the impact sound of the movable assembly and the fixed assembly; the positioning piece 50 supports the sliding seat 400, so that the sliding seat 400 is subjected to the supporting force of the positioning piece 50, the supporting force and the supporting force applied to one end face of the cap head 414 by the first elastic piece 310 form clamping force, the sliding seat 400 is prevented from loosening in the inner groove 203, and the service life of the hinge is effectively prolonged; the positioning piece 50, the sliding seat 400 and the second fixing piece 20 are installed in a matched mode, and operation is simple.
Finally, it should be noted that: the above is only a preferred embodiment of the present invention, and the present invention is not limited thereto, but it is to be understood that the present invention is described in detail with reference to the foregoing embodiments, and modifications and equivalents of some of the technical features described in the foregoing embodiments may be made by those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
