Detailed Description
The present invention will be described in detail with reference to the embodiments shown in the drawings, and reference is made to fig. 1 to 3, which are preferred embodiments of the present invention.
Referring to fig. 1 to 3, a door hinge mechanism 100 according to the present invention is shown, where the door hinge mechanism 100 is used to be installed on a device having a door to automatically close the door.
The door body hinge mechanism 100 comprises a hinge seat 1 and a power-assisted door closing device 2 for assisting in closing the door, wherein when the door body is closed, the power-assisted door closing device 2 provides power to achieve automatic closing of the door body.
Specifically, the hinge seat 1 comprises a fixing portion 11 for being fixed on a box body and a hinge seat body 12 connected with the fixing portion 11 to be matched with the door body, the plane where the hinge seat body 12 is located is in a horizontal state, a hinge shaft 13 extending in the vertical direction is arranged on the hinge seat body 12, and the door body is rotatably connected to the hinge seat 1 through the hinge shaft 13, so that the door body can be opened and closed through rotating.
The power-assisted door closing device 2 comprises an eccentric cam 21 fixedly connected to the hinge shaft 13, a shell 22 fixed to the door body, an elastic assembly 23 extending in the horizontal direction, a sliding piece 24 moving along the periphery of the eccentric cam 21 in the process of opening and closing the door body, and a limiting piece 25 fixedly connected to the sliding piece 24 to limit the sliding piece 23, wherein one end, far away from the sliding piece 24, of the limiting piece 25 is rotatably connected with the shell 22, one end, close to the hinge base 1, of the elastic assembly 23 is rotatably connected with the sliding piece 24, and one end, far away from the hinge base 1, of the elastic assembly 23 is rotatably connected with the shell 22.
It can be understood that a triangle is defined by a connecting line between the axis of rotation of the limiting member 25 and the axis of rotation of the elastic component 23, the limiting member 25 and the elastic component 23, and in the process of opening and closing the door body, the length of the elastic component 23 changes, so that the limiting member 25 and the elastic component 23 are linked to rotate by a certain angle.
The eccentric cam 21 includes a fixing portion 211 fixedly coupled to the hinge shaft 13, and a flange portion 212 coupled to the fixing portion 211 to be engaged with the slider 24.
Specifically, the cross section of the portion of the hinge shaft 13, which is engaged with the fixing portion 211, is non-circular, the fixing portion 211 is provided with a shaft hole 2111, which is engaged with the shape of the hinge shaft 13, and after the eccentric cam 21 is fixed on the hinge shaft 13, the eccentric cam 21 cannot rotate around the hinge shaft 13.
Of course, the hinge shaft 13 and the eccentric cam 21 may be connected together by a pin to limit the eccentric cam 21 from rotating around the hinge shaft 13.
The flange portion 212 includes a front flange portion 2121 facing the front side and a rear flange portion 2122 facing the rear side, and a connection point of the front flange portion 2121 and the rear flange portion 2122 is a critical point. In the process that the slider 24 moves forward along the rear flange portion 2122 to the critical point or moves backward from the front flange portion 2121 to the critical point, the compression amount of the elastic element 23 is gradually increased, and accordingly, the elastic restoring force of the elastic element 23 is also gradually increased, and when the slider 24 moves to the critical point, the compression amount of the elastic element 23 is maximum, and accordingly, the elastic restoring force of the elastic element 23 is also maximum.
When the door body is in a closed state, the sliding member 24 is located at one end of the rear flange portion 2122 away from the front flange portion 2121, and after the door body is opened to a maximum opening angle, the sliding member 24 is located at one end of the front flange portion 2121 away from the rear flange portion 2122.
Meanwhile, in the process of opening and closing the door body, the sliding member 24 always abuts against the flange portion 212 and moves along the flange portion 212 under the elastic restoring force of the elastic assembly 23 and the limiting action of the limiting member 25.
Specifically, in the process of closing the door body by a user, after the door body is manually closed until the sliding member 24 is located at the critical point, the door body is slightly pushed towards the door closing direction, so that the sliding member 24 moves to the rear flange portion 2122, and the sliding member 24 abuts against the rear flange portion 2122 under the action of the elastic restoring force of the elastic component 23 and the limiting action of the limiting member 25 and moves backwards along the rear flange portion 2122, so as to provide assistance for the door body, so as to drive the door body to be automatically closed, and the door body closing device is simple in structure, convenient to operate and relatively stable in operation.
Similarly, in the process of opening the door body by a user, after the door body is manually opened until the sliding member 24 is located at the critical point, the door body is slightly pulled towards the door opening direction to make the sliding member 24 move to the front flange part 2121, the sliding member 24 abuts against the front flange part 2121 under the action of the elastic restoring force of the elastic component 23 and the limiting action of the limiting member 25 and moves in the direction away from the rear flange part 2122 along the front flange part 2121, so that the door body is assisted to drive the door body to be automatically opened.
The horizontal direction is not limited to a standard horizontal direction, i.e. the extending direction of the elastic member 23 may have a small angle with the horizontal direction.
The elastic assembly 23 is in a compressed state during the movement of the slider 24 along the flange portion 212, so that the slider 24 can be supported on the flange portion 212 and move along the flange portion 212 under the driving of the elastic restoring force of the elastic member body 231, thereby providing an assisting force during the door closing and/or opening process, and realizing automatic door closing and/or automatic door opening.
Specifically, the elastic assembly 23 includes an elastic member body 231, a first fixing block 232 located at an end of the elastic member body 231 remote from the hinge base 1, and a second fixing block 233 located at an end of the elastic member body 231 near the hinge base 1.
The first fixing block 232 is rotatably connected to the housing 22, so that the elastic component 23 is rotatably connected to the housing 22, and can rotate by a certain angle under the linkage action of the limiting member 25, thereby enhancing the stability of the operation of the power-assisted door closing device 2 in the process of opening and closing the door body.
The elastic body 231 is a spring, but the elastic body 231 may be other elastic members.
The sliding member 24 is rotatably connected to the second fixing block 233, and in the process that the sliding member 24 moves along the flange portion 212, the sliding member 24 rotates in comparison with the elastic component 23 according to the shape of the flange portion 212 in contact with the sliding member 24, so that the sliding member 24 can always abut against the flange portion 212 and move along the flange portion 212, and the operation stability of the assisted door closing device 2 in the process of opening and closing the door body is enhanced.
The sliding member 24 includes a fixing seat 241 rotatably connected to the elastic member 24, a roller 242 located on a side of the fixing seat 241 away from the elastic member 23, and a rotating shaft 243 for rotatably connecting the roller 242 to the fixing seat 241, wherein the rotating shaft 243 extends in an up-and-down direction; during the door opening and closing process, the roller 242 moves along the flange portion 212 to reduce the friction between the sliding member 24 and the flange portion 212, and further facilitate the movement of the sliding member 24 along the flange portion 212.
Specifically, the fixing base 241 is rotatably connected to the second fixing block 233.
The limiting member 25 is fixedly connected to the fixing seat 241, and meanwhile, one end of the limiting member 25, which is far away from the sliding member 24, is rotatably connected to the housing 22.
In the process of opening and closing the door body to move the slider 24 along the flange portion 212, on one hand, the limiting member 25 limits the rotation angle of the slider 24 relative to the elastic component 23, so as to prevent the slider 24 from separating from the flange portion 212 under the elastic restoring force of the elastic component 23, and the roller 242 always abuts against the flange portion 212 and moves along the periphery of the flange portion 212; on the other hand, the elastic assembly 23 is linked to finely adjust the position of the elastic assembly 23, so as to enhance the running stability of the power-assisted door closing device 2 in the process of opening and closing the door body.
Further, the power-assisted door closing device 2 further includes a linear compression damper 26 for providing a damping force when the elastic component 23 deforms, so as to slow down a speed of switching the elastic component body 231 from a compression state to a free state under an elastic restoring force in a door closing process, so that the door body is automatically and slowly closed, the door body is prevented from being rapidly closed and colliding with a box body, and the door closing noise is reduced.
The linear compression damper 26 extends axially in the same direction as the deformation of the elastic member 23.
Specifically, two ends of the linear compression damper 26 are respectively fixed to the first fixing block 232 and the second fixing block 233, so that in the process that the elastic member body 231 drives the door body to automatically close, a damping force is provided for the elastic member body 231, the door body is prevented from being rapidly closed and colliding with a box body, and the door closing noise is reduced.
The linear compression damper 26 includes a housing 261 and a piston rod 262 at least partially inserted into the housing 261, and the piston rod 262 is capable of moving along the axial direction of the linear compression damper 26 to change the length of the linear compression damper 26, so that the length of the linear compression damper 26 is consistent with the length of the elastic member body 231 during the opening and closing of the door body.
Specifically, one end of the housing 261, which is far away from the piston rod 262, is fixedly connected to the second fixed block 233, and one end of the piston rod 262, which is far away from the housing 261, is fixedly connected to the first fixed block 232.
The elastic member body 231 is sleeved on the linear compression damper 26, that is, the spring is sleeved on the linear compression damper 26, and meanwhile, one end of the spring abuts against the first fixing block 232 and the other end abuts against the second fixing block 233, so that the spring can be prevented from being bent and the sliding member 24 can be moved along the deformation direction of the spring in the process that the sliding member 24 moves along the flange portion 212.
In the process of opening the door, the sliding member 24 moves along the rear flange portion 2122 toward the front flange portion 2121, and at the same time, the sliding member 24 drives the second fixing block 233 to move toward the first fixing block 232, and at this time, the piston rod 262 retracts into the housing 261 to reduce the length of the linear compression damper 26, and the spring is in a compressed state.
In the process of closing the door, after the user manually closes the door body to move the sliding member 24 to the critical point, the sliding member 24 abuts against the rear flange portion 2122 under the action of the elastic restoring force of the spring, and at the same time, the second fixing block 233 moves in the direction away from the first fixing block 232 under the action of the elastic restoring force of the spring and drives the sliding member 24 to move along the moving rear flange portion 2122 in the direction away from the front flange portion 2121, so as to drive the door body to automatically close, and at the same time, the piston rod 262 moves in the direction away from the housing 261 under the action of the sliding member 24 to provide a damping force to the spring, so as to slow down the speed of switching the spring from the compression state to the free state under the action of the elastic restoring force, so that the door body is automatically and slowly closed, and the door body is prevented from colliding with the box body due to rapid closing, reduce the noise of closing the door.
