Referring to fig. 1 and 2, the hinge according to the embodiment of the first aspect of the present utility model includes a fixed end link 100, a movable end link 200, and a link assembly 300, wherein the link assembly 300 connects the fixed end link 100 and the movable end link 200, and the link assembly 300 has a folded state and an unfolded state; the link assembly 300 includes two acting links 301 which are indirectly connected and oppositely disposed, one of the two acting links 301 is provided with a buffer member 400, and the other acting link 301 is provided with a buffer acting piece 321 which is matched with the buffer member 400; in the case where the unfolding angle of the link assembly 300 is not greater than the preset angle during the switching of the link assembly 300 from the unfolded state to the folded state, the buffer gear 321 presses the buffer member 400. The unfolded state may refer specifically to fig. 1, and the folded state may refer specifically to fig. 2.

According to the hinge of the embodiment of the utility model, the buffer component 400 is arranged on one of the action connecting rods 301, the buffer action piece 321 is arranged on the other action connecting rod 301, the two action connecting rods 301 cannot interfere with each other, the buffer component 400 can be effectively prevented from occupying the space of the hinge, the compactness of the hinge is ensured, the possibility that the size and the structure of the connecting rod assembly 300 are limited is reduced, and the integral structural strength and the bearing capacity of the hinge are improved.

It is understood that two active links 301 refer to two links in the linkage assembly 300 that satisfy both the indirect connection and the opposing arrangement. Wherein, indirect connection refers to two connecting rods which are not directly connected. By opposed, it is meant that the two links have a relationship of relative movement during the switching of the expanded state of the linkage assembly 300 to the collapsed state, with the two links at least partially overlapping during this process. When the connection relationship of the hinge is the case in fig. 1, the first link 310 and the second link 320 are two acting links 301, and the third link 330 and the fourth link 340 are two acting links 301.

Of course, the link assembly 300 may be a more complex six-link assembly 300 or an eight-link assembly 300 or other number of link assemblies 300, and the present utility model is not limited to the number of links and the connection relationship of the link assemblies 300, as long as two links of the link assembly 300 simultaneously satisfy two conditions of indirect connection and opposite arrangement, that is, the acting link 301 of the present utility model.

It will be appreciated that the cushioning member 400 may slow the hinge closing speed, prevent the user from being pinched, and effectively improve the safety of the hinge closing. In the process of continuously switching the connecting rod assembly 300 from the unfolding state to the folding state, the two acting connecting rods 301 move relatively, under the condition that the unfolding angle of the connecting rod assembly 300 is not larger than a preset angle, the buffering acting piece 321 and the buffering component 400 are in contact, the buffering component 400 is extruded by the buffering acting piece 321, and as the preset angle is reduced, the extrusion degree of the buffering component 400 is larger, continuous resistance is generated, and the effect of reducing the speed and closing is achieved.

It should be noted that the link assembly 300 has a folded state and an unfolded state, wherein the folded state of the link assembly 300 may be understood as a state in which the movable end link 200 approaches the fixed end link 100 by the rotation of the links in the link assembly 300. Similarly, the unfolded state of the link assembly 300 may be understood as a state in which the movable end link 200 is separated from the fixed end link 100 by the rotation of the links in the link assembly 300. The expansion angle of the link assembly 300 may be understood as an angle by which the movable end link 200 is rotated compared to the initial position of the movable end link 200 in the folded state.

In the process of switching the link assembly 300 from the unfolded state to the folded state, the buffer 321 is in contact with the fixed-end link 100 when the unfolded angle of the link assembly 300 is a preset angle. As the deployment angle of the link assembly 300 gradually decreases, the cushioning effect 321 continuously compresses the cushioning body, thereby achieving slow closure of the hinge.

It will be appreciated that compression of the cushioning body by the cushioning effect 321 will generate a reaction force such that, if the angle of deployment of the linkage assembly 300 is not greater than a predetermined angle, a resistance force is generated to switch the linkage assembly 300 from the deployed state to the folded state.

It is understood that the predetermined angle is an opening angle at which the buffer member 321 presses the buffer member 400.

For example, when the preset angle is 30 °, the cushioning effect 321 contacts the cushioning member 400 when the expansion angle of the link assembly 300 is between 0 ° and 30 °, and the cushioning member 400 receives a greater degree of compression as the link assembly 300 rotates toward the folded state.

Of course, the preset angles may be 10 °, 15 °, 20 °, 25 °, 30 °, 35 °, 40 °, 45 ° and the like, which are not particularly limited, and may be determined according to the application scenario of the hinge.

In one embodiment, in the case where the deployment angle of the link assembly 300 is greater than the preset angle, the buffer acting piece 321 and the buffer member 400 do not contact, in other words, when the deployment angle of the link assembly 300 is greater than the preset angle, the buffer member 400 does not generate resistance, so that the user can continue to deploy the link assembly 300.

Of course, in the case where the expansion angle of the link assembly 300 is greater than the preset angle, the buffer acting member 321 and the buffer member 400 may be contacted as long as the user is not influenced to continue to expand the link assembly 300.

Referring to fig. 1, according to an embodiment of the present utility model, a buffering part 400 includes a damper 410 and a damping push rod 420, and the damping push rod 420 is at least partially installed inside the damper 410; the damper push rod 420 is connected to the acting link 301, and the damper acting member 321 contacts the damper 410 in case that the expansion angle of the link assembly 300 is not greater than a preset angle during the switching of the link assembly 300 from the expanded state to the collapsed state, or the damper 410 is connected to the acting link 301, and the damper acting member 321 contacts the damper push rod 420 in case that the expansion angle of the link assembly 300 is not greater than a preset angle during the switching of the link assembly 300 from the expanded state to the collapsed state.

It will be appreciated that when damper 410 is compressed by damper pushrod 420, damper pushrod 420 compresses the gas or liquid in damper 410, and damper 410 resists. This resistance can absorb and dissipate energy, making the system's course of motion smoother and more stable.

Cushioning member 400 may also be a separate member, for example, cushioning member 400 may be a spring member or a flexible material having elasticity. When the buffer member 400 is compressed by the buffer member 321, the elastic buffer member 400 has elastic potential energy to generate resistance.

According to one embodiment of the present utility model, the cushioning effect 321 is a boss member provided to the effect link 301. The boss part may be integrally formed with the acting connecting rod 301, may be fixedly connected with the acting connecting rod 301, or may be detachably mounted with the acting connecting rod 301.

It will be appreciated that the boss member may be integrally formed with the action link 301 to prevent loosening or rocking between the boss member and the action link 301, ensuring uniform pressure distribution, and avoiding loss of pressure control due to loosening.

Of course, the boss member may be fixedly connected to the action link 301, and the fixing connection manner includes, but is not limited to, welding, gluing, and the like.

It will be appreciated that the boss member is detachably mounted to the action link 301, so that a user can conveniently replace boss members of different models to achieve different extrusion effects. The detachable connection mode comprises, but is not limited to, a slide rail type, a magnetic attraction type, a clamp type, a clamping type and the like.

According to one embodiment of the utility model, the active link 301 to which the cushioning member 400 is attached is provided with a recess 302, and the cushioning member 400 is at least partially positioned within the recess 302. It will be appreciated that the recess 302 may provide a receiving space for the cushioning member 400 such that the cushioning member 400 may be more stably coupled to the apply link 301. In addition, the recess 302 is further adapted to form a relief space 322 of the corresponding active link 301, and in the folded state, the corresponding active link 301 may be at least partially located in the recess 302 of the active link 301, so that the occupied space of the link assembly 300 in the folded state may be reduced.

According to an embodiment of the present utility model, the hinge further includes an elastic assembly 500, the elastic assembly 500 includes an elastic body 510 and an elastic acting member 520, one of the elastic body 510 and the elastic acting member 520 is disposed at the movable end link 200, and the other is disposed at the link assembly 300; in the process of switching the link assembly 300 from the folded state to the unfolded state, the elastic acting member 520 compresses the elastic body 510 in the case that the unfolded angle of the link assembly 300 is not greater than the preset angle; in the process of switching the link assembly 300 from the unfolded state to the folded state, the elastic body 510 drives the link assembly 300 to switch toward the folded state when the unfolded angle of the link assembly 300 is not greater than the preset angle.

It will be appreciated that the spring action 520 compresses the spring body 510 to form a spring potential energy during the switching of the linkage assembly 300 from the collapsed state to the expanded state. In the case that the unfolding angle of the link assembly 300 is not greater than the preset angle, the elastic potential energy of the elastic assembly 500 is released to automatically close the hinge, and at the same time, the damper 410 acts to make the closing speed of the hinge relatively slow, so that the impact is avoided.

When the link assembly 300 is in the folded state, the buffer acting member 321 is contracted toward the inside of the buffer body, and simultaneously, the compression amount of the elastic body 510 is reduced.

It will be appreciated that the elastic body 510 is elastically deformed by the compression of the acting member, and the compressed elastic body 510 has an elastic restoring force, so that when the link assembly 300 is switched from the folded state to the unfolded state, the link assembly 300 tends to be switched from the unfolded state to the folded state. The elastic body 510 may be a spring, or may be a flexible material having elasticity such as rubber. Of course, the elastic body 510 may also include other elastic components, for example, the elastic body 510 is a piston, and when compressed by the acting element, the push rod of the piston compresses and presses the gas or the liquid in the piston, so that the elastic body 510 has elastic restoring force. In the embodiment of the present application, the elastic body 510 may include a member capable of generating an elastic restoring force when compressed.

It should be noted that, when the expansion angle of the link assembly 300 is not greater than the preset angle, the elastic body 510 drives the link assembly 300 to switch toward the folded state, that is, when the angle of rotation of the movable end link 200 is less than or equal to a certain critical value compared to the folded state, the outer edges of the acting member and the elastic body 510 can be always kept in contact, and the acting member compresses the elastic body 510, and the elastic restoring force of the elastic body 510 makes the link assembly 300 have a closing tendency, in other words, the link assembly 300 can switch from the expanded state to the folded state spontaneously without the action of the external force. Of course, in the case where the expansion angle of the link assembly 300 is not greater than the preset angle, the outer edges of the acting element and the elastic body 510 may be separated, and the separation herein may be understood that the elastic body 510 and the acting element are not in contact.

For example, when the preset angle is 30 °, the expansion angle of the link assembly 300 is between 0 ° and 30 °, the outer edges of the acting element and the elastic body 510 may always be kept in contact, and the acting element compresses the elastic body 510 to store elastic potential energy.

For another example, when the preset angle is 30 °, the outer edges of the acting member and the elastic body 510 are always attached corresponding to the case where the expansion angle of the link assembly 300 is between 10 ° and 30 °, and the outer edges of the acting member and the elastic body 510 are detached corresponding to the case where the expansion angle of the link assembly 300 is between 0 ° and 10 °, and at this time, the link assembly 300 may continue to be closed by inertia.

When the expansion angle of the link assembly 300 is greater than the preset angle, the acting member does not compress the elastic body 510 or the restoring elasticity is small, the link assembly 300 does not spontaneously switch from the expanded state to the folded state, and the movable end link 200 can be easily rotated.

According to one embodiment of the present utility model, the link assembly 300 is provided with the escape groove 350, and at least a portion of the elastic body 510 is located in the escape groove 350 in the folded state. It is appreciated that the avoidance groove 350 can prevent the jamming or engagement between the components of the link assembly 300 in the folded state, protect the elastic body 510, and reduce the space occupied by the elastic body 510 for the link assembly 300 in the folded state.

In one embodiment, the buffer member 400 is provided to the first link 310, and the second link 320 is provided with a buffer 321. In this case, only the second link 320 and the first link 310 are engaged, and the buffer member 400 does not limit the size and structure of the third link 330 and the fourth link 340, so that the strength of the third link 330 and the fourth link 340 can be greater, improving the durability and the service life of the hinge as a whole.

According to one embodiment of the present utility model, the second link 320 is bent to form the escape space 322, and at least a portion of the third link 330 is positioned in the escape space 322 in the folded state. It can be appreciated that the second link 320 is bent to form the avoidance space 322 without affecting the connection of the second link 320 and the fixed end link 100, the second link 320 and the third link 330, and the second link 320 and the fourth link 340, and the third link 330 can be partially located in the avoidance space 322, so that the limited space can be more effectively utilized, the occupied space of the link assembly 300 can be reduced, and the compactness of the link assembly 300 can be further increased.

According to one embodiment of the present utility model, the fixed end link 100 is formed with a mounting groove 110, and the link assembly 300 is at least partially positioned in the mounting groove 110 in the folded state. It will be appreciated that in the folded state, the first and second mounting grooves 110 and 110 form a receiving cavity to wrap the link assembly 300, thereby protecting the link assembly 300. The first mounting groove 110 and the second mounting groove 110 are groove-shaped, the link assembly 300 is at least partially located in the first mounting groove 110, and the link assembly 300 is at least partially located in the second mounting groove 110, and the first mounting groove 110 and the second mounting groove 110 can reduce the occupied space of the link assembly 300 in the folded state.

The storage cabinet body is internally provided with an accommodating space, and one side of the storage cabinet body is provided with an opening communicated with the accommodating space; the door body is arranged at the opening and is suitable for opening or closing the opening; the connecting rod assembly 300 is connected with the locker body and the door body, and the connecting rod assembly 300 has a folded state and an unfolded state; the link assembly 300 includes two acting links 301 which are indirectly connected and oppositely disposed, one of the two acting links 301 is provided with a buffer member 400, and the other acting link 301 is provided with a buffer acting piece 321 which is matched with the buffer member 400; in the case where the unfolding angle of the link assembly 300 is not greater than the preset angle during the switching of the link assembly 300 from the unfolded state to the folded state, the buffer gear 321 presses the buffer member 400.

It is understood that the unfolding angle of the link assembly 300 can be understood as an angle by which the movable end link 200 is rotated compared to the initial position of the folded state of the movable end link 200, in other words, an unfolding angle of the door body is an unfolding angle of the link assembly 300. When the door opening angle is not greater than the preset angle of the connecting rod assembly 300, the buffer assembly can form resistance, so that the closing speed of the door can be reduced, the user is prevented from being clamped, and the safety of the storage cabinet is effectively improved.
