Embodiments of the first aspect of the present invention, as shown in fig. 1 to 9, provide a hinge assembly, which includes a first hinge body 100 and a second hinge body 200 rotatably connected to the first hinge body 100. When the first hinge body 100 is connected to the cabinet 400, the second hinge body 200 is connected to the door (the second hinge body 200 may be connected to the door through the end cap 500), and the door may rotate to open and close relative to the cabinet 400. Of course, the first hinge body 100 is not limited to be connected to the cabinet 400, and may also be connected to a door frame, and the door body may be opened and closed in a rotating manner relative to the door frame.

The first hinge body 100 is provided with one of a hinge groove 210 and a hinge shaft 110 rotatably connected in the hinge groove 210, and the first hinge body 100 is further provided with one of a limit groove 220 and a limit shaft 120 arranged in the limit groove 220; the second hinge body 200 is provided with the other one of the hinge shaft 110 and the hinge groove 210, and the second hinge body 200 is further provided with the other one of the limiting shaft 120 and the limiting groove 220; the hinge shaft 110 and the hinge groove 210 relatively rotate, so that the limiting shaft 120 and the limiting groove 220 relatively move along the extending direction of the limiting groove 220; the elastic limiting member 300 is disposed in the limiting groove 220 to reduce the width of the predetermined position in the limiting groove 220, and the limiting shaft 120 is adapted to overcome the resistance of the elastic limiting member 300 and pass through the predetermined position.

The hinge shaft 110 rotates in the hinge groove 210, so that the first hinge body 100 and the second hinge body 200 rotate relatively, and the opening and closing adjustment of the door body can be realized; in addition, during the rotation of the hinge shaft 110, the limit shaft 120 moves along the extending direction of the limit groove 220, the limit shaft 120 moves to the position of the elastic limiting member 300, the elastic limiting member 300 reduces the width of the preset position in the limit groove 220, and at the preset position, the elastic limiting member 300 provides resistance for the continuous movement of the limit shaft 120, so that the limit shaft 120 passes through the preset position by overcoming the resistance of the elastic limiting member 300. The elastic limiting member 300 is disposed such that the limiting shaft 120 can decelerate and can be limited to one side of the predetermined position. The elastic limiting member 300 is disposed in the limiting groove 220, so that a conventional self-locking structure, such as a stopping structure, between the cabinet 400 and the door body can be omitted, and the manufacturing cost can be reduced.

When the door body is in a closed state, the limiting shaft 120 is located at the first end of the limiting groove 220, and when the door body is opened to the maximum angle, the limiting shaft 120 is located at the second end of the limiting groove 220.

Referring to fig. 4 and 6, when the elastic limiting member 300 is disposed near the first end of the limiting groove 220, when the door body is closed towards the cabinet 400, the limiting shaft 120 can move to the first end through the preset position, and when the door body passes through the preset position, the elastic resistance of the elastic limiting member 300 can reduce the rotation speed of the door body, thereby reducing the impact force of the door body on the cabinet 400. In addition, the elastic limiting member 300 can also limit the limiting shaft 120 at the first end, and the elastic limiting member 300 prevents the limiting shaft 120 from moving towards the opening direction of the door body, so that a self-locking function is achieved.

When the elastic limiting member 300 is close to the second end of the limiting groove 220, when the door body is opened relative to the cabinet body 400, the limiting shaft 120 can move to the second end through the preset position, and when the door body is in the preset position, the elastic resistance of the elastic limiting member 300 can reduce the rotating speed of the door body, so that the impact acting force of the door body opening process on the hinge assembly is reduced, and the safety and the structural stability of the hinge assembly are improved. In addition, the elastic limiting piece 300 can also limit the limiting shaft 120 at the second end, and the elastic limiting piece 300 can prevent the limiting shaft 120 from moving towards the closing direction of the door body, so that the door body is kept at the maximum opening angle, and the door body is prevented from shaking.

The elastic limiting member 300 is close to the first end (or the second end) of the limiting groove 220, and it is required to ensure that the first end (or the second end) can accommodate the limiting shaft 120. When the second lubrication sleeve 121 is sleeved on the limiting shaft 120 in the following embodiments, the first end (or the second end) needs to be able to accommodate the second lubrication sleeve 121. Here, the extending directions of the hinge groove 210 and the stopper groove 220 may be both understood as the length direction of the groove, i.e., the direction perpendicular to the axial direction of the hinge shaft 110 and the axial direction of the stopper shaft 120. The width of the predetermined position in the limiting groove 220 is a distance perpendicular to the length direction of the groove. The width of the limiting shaft 120 is the maximum distance along the width direction of the limiting groove 220, and when the limiting shaft 120 is a cylindrical shaft, the width of the limiting shaft 120 is the diameter of the cylinder.

Of course, the elastic limiting member 300 may also be disposed at other positions in the limiting groove 220 to limit the limiting shaft 120 at a plurality of positions in the limiting groove 220, so that the door body may be fixed to the cabinet 400 at a plurality of opening angles. That is, one or more preset positions may be provided in the limiting groove 220, and the preset positions may be selected as needed.

Referring to fig. 1, the first hinge body 100 is provided with a hinge shaft 110 and a limit shaft 120, and the second hinge body 200 is provided with a hinge groove 210 and a limit groove 220; or, the first hinge body is provided with a hinge shaft and a limiting groove (not shown in the figure), and the second hinge body is provided with a hinge groove and a limiting shaft; or, the first hinge body is provided with a hinge groove and a limit groove (not shown in the figure), and the second hinge body is provided with a hinge shaft and a limit shaft; or, the first hinge body is provided with a hinge groove and a limit shaft (not shown in the figure), and the second hinge body is provided with a hinge shaft and a limit groove.

The above-mentioned combination mode of the first hinge body 100 and the second hinge body 200 has the same operation principle, and in the following embodiments, the description will be given by taking "the hinge shaft 110 and the limit shaft 120 are provided on the first hinge body 100, and the hinge groove 210 and the limit groove 220 are provided on the second hinge body 200" as an example, as shown in fig. 1.

The following provides an example of the structure of the elastic limiting member 300.

In one embodiment, referring to fig. 1 and 2, the elastic limiting member 300 includes a first limiting portion 340 and a second limiting portion 350 disposed opposite to each other, the first limiting portion 340 and the second limiting portion 350 limit an opening end 310 facing the extending direction of the limiting groove 220, the opening end 310 is located at a predetermined position, the opening width of the opening end 310 is smaller than the width of the limiting shaft 120, and the limiting shaft 120 overcomes the elastic resistance of the opening end 310 to pass through the predetermined position. The limiting shaft 120 passes through the preset position by expanding the width of the opening end 310, and after the limiting shaft 120 passes through the preset position, the first limiting portion 340 and the second limiting portion 350 return.

The first limiting part 340 and the second limiting part 350 are oppositely arranged, when the limiting shaft 120 passes through the preset position, two sides of the limiting shaft 120 are stressed, and the stress of the limiting shaft 120 is more uniform; moreover, the elastic limiting member 300 is stressed symmetrically on both sides, so that the stress of the elastic limiting member 300 is more uniform, which is helpful for ensuring the service life of the elastic limiting member 300 and the limiting shaft 120.

Referring to fig. 3, after the door body and the cabinet 400 are closed, the open end 310 limits the limiting shaft 120, so as to perform a self-locking function of the door body and the cabinet 400; of course, the opening end 310 may be located at other positions in the limiting groove 220 to limit the door body at different positions, and may be selected according to the requirement.

In one embodiment, referring to fig. 2, the first position-limiting portion 340 is connected to the second position-limiting portion 350 and limits the closed end 320, the limiting shaft 120 is suitable for being limited between the closed end 320 and the open end 310, and the closed end 320 is disposed at the end of the limiting groove 220. The closed end 320 limits the limiting shaft 120 at the end of the limiting groove 220. The closed end 320 can confine the stopper shaft 120 therein even if the stopper groove 220 is provided with an opening. When the elastic limiting piece is located at the second end of the limiting groove, the closed end can limit the maximum opening angle of the first hinge body and the second hinge body.

It should be noted that the space between the closed end 320 and the open end 310 is to accommodate the spacing shaft 120. The shape of the closed end 320 is matched with the shape of the limiting shaft 120, so as to ensure that the limiting shaft 120 can be stably limited in the elastic limiting member 300.

In one embodiment, the first and second position-limiting portions limit two open ends (not shown), and the position-limiting shaft is adapted to be limited between the two open ends. At the moment, the elastic limiting part can be located at any position of the limiting groove, the two opening ends can limit the limiting shaft from two directions, and the elastic limiting part can limit the limiting shaft when the door body is closed towards the cabinet body and the door body is opened relative to the cabinet body.

When the position of the opening end corresponds to the position of the door body which is opened by a preset angle relative to the cabinet body, the limiting shaft enters the elastic limiting part through the opening end, and the elastic limiting part limits the limiting shaft in the elastic limiting part, so that the door body is kept at the position of opening the preset angle.

The preset angle ranges between the maximum angle and 0 °, and the maximum angle is generally 120 °.

One or more elastic limiting members 300 may be disposed in the limiting groove 220, and elastic limiting members of different structures may be disposed in the limiting groove 220. For example, two ends of the limiting groove 220 are respectively provided with an elastic limiting member having a closed end 320, and the elastic limiting members having two open ends are respectively arranged in the limiting groove 220 corresponding to positions of the door body opened by 60 degrees and 90 degrees.

In one embodiment, the resilient stop 300 is integrally formed from a sheet of material. If the elastic limiting member 300 is made of plastic, rubber, or the like, the elastic limiting member can be formed by integral injection molding, and if the elastic limiting member 300 is made of metal, the elastic limiting member can be formed by bending, so that the elastic limiting member can be processed simply and conveniently, and the processing mode can be adjusted according to the material. Referring to fig. 2, the elastic limiting member 300 has an open end and a closed end, and is integrally formed, and has a simple structure and is convenient to assemble.

When the first limiting part and the second limiting part of the elastic limiting part limit two opening ends, the first limiting part and the second limiting part can be independent parts and are respectively and independently processed. Of course, at this time, the first limiting portion and the second limiting portion may also be fixedly connected, for example, by a connecting plate or a connecting strip disposed on the bottom wall of the limiting groove.

The following provides an example of the connection manner of the elastic limiting member 300.

In one embodiment, as shown in fig. 1 to 8, the elastic limiting member 300 is detachably connected to the limiting groove 220, so that the elastic limiting member 300 can be replaced easily and the installation is simple.

The elastic limiting member 300 can be fixed to the first hinge body 100 or the second hinge body 200 by inserting, so that the fixing manner is simple and convenient, and the assembly and disassembly are convenient.

Referring to fig. 1 to 3, the insertion groove 230 is communicated with the limiting groove 220, which facilitates processing. It should be noted that the insertion groove 230 and the limiting groove 220 need to be disposed on the first hinge body 100 or the second hinge body 200 at the same time, but the insertion groove 230 is not limited to be communicated with the limiting groove 220, and the insertion groove 230 may be independent of the limiting groove 220, for example, the folded portion of the elastic limiting member is folded from top to bottom, and at this time, the insertion groove is disposed on the periphery of the limiting groove, so that the folded portion is conveniently inserted and fixed downward.

Certainly, the fixing manner of the elastic limiting member 300 and the limiting groove 220 is not limited to fixing through the inserting groove 230, and can also be fixed through clamping or magnetic attraction, and if the elastic limiting member 300 is fixed through magnetic attraction, the limiting shaft 120 is made of ferromagnetic material, and the magnetic field attraction can further limit the limiting shaft 120, so as to ensure that the limiting shaft 120 is accurately positioned at the preset position.

It should be noted that, the elastic limiting member 300 and the limiting groove 220 may also be fixedly connected in an integrated manner, at this time, the elastic limiting member 300 may be an elastic sheet, an elastic block, or other structures, and the elastic sheet and the elastic block may be attached to the inner wall of the limiting groove 220, so as to reduce the width of the limiting groove 220, and the structure is simple. The elastic sheet and the elastic block can be made of rubber, flexible plastic and the like.

The first lubricating shaft sleeve 111 can be made of a self-lubricating material, so that the structure of the first lubricating shaft sleeve 111 can be simplified.

Or, the first anti-friction member is a first ball coupled to the hinge shaft 110, and the first ball may be provided at an end of the hinge shaft 110 such that the first ball contacts the bottom wall of the hinge groove 210; the first ball may also be provided at a side of the hinge shaft 110 such that the first ball contacts a sidewall of the hinge groove 210. The first ball is provided to reduce friction of the hinge shaft 110 with the hinge groove 210. Wherein the first ball is rollingly coupled to the hinge shaft 110 in a manner similar to a ball at an end of a ball point pen or a ball in a bearing.

In an embodiment, a second anti-friction member is disposed between the limiting shaft 120 and the limiting groove 220, the second anti-friction member plays a role in lubricating the limiting shaft 120 and the limiting groove 220, and the structure and the working principle of the second anti-friction member are similar to those of the first anti-friction member.

In one embodiment, the second anti-friction member is a second lubrication sleeve 121 sleeved outside the limiting shaft 120, or the second anti-friction member is a second ball connected to the limiting shaft 120. The lubrication principle of the second lubrication shaft sleeve 121 is the same as that of the first lubrication shaft sleeve 111, and details are not repeated here, and reference may be made to the above-described embodiment of the first lubrication shaft sleeve 111; the lubrication principle of the second ball is the same as that of the first ball, and the description is omitted here, and reference may be made to the above-mentioned embodiment of the first ball.

It should be noted that the first friction reducing member and the second friction reducing member may be provided simultaneously, as shown with reference to fig. 1 to 8. It should also be noted that the first antifriction component can also be fixed in the hinge groove, and in the same way, the second antifriction component can be fixed in the limiting groove and also can play a role in reducing friction.

In one embodiment, as shown in fig. 1 to 8, the hinge slot 210 is an elongated slot, the hinge slot 210 includes a first position 211 close to the position-limiting slot 220 and a second position 212 far from the position-limiting slot 220, the position-limiting slot 220 includes a first slot portion 221 and a second slot portion 222 communicated with each other, and the second slot portion 222 extends in a direction far from the hinge slot 210 relative to the first slot portion 221; the limiting shaft 120 is located at the first position 211, the limiting shaft 120 is located in the second groove 222, and the first hinge body 100 is close to the second hinge body 200; the limiting shaft 120 is located at the second position 212, the limiting shaft 120 is located in the first groove 221, and the first hinge body 100 is far away from the second hinge body 200.
