Detailed Description

The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.

For convenience of description, the side of the door body 2 opened by rotation is defined as the front side, and the side of the box body 1 is defined as the rear side, with reference to the door body being in a closed state when the furniture 100 such as a refrigeration device is normally installed and used; one side close to the ground is the lower side or the bottom side; the side facing away from the ground is the upper or top side.

As shown in FIG. 1, a piece of furniture 100 according to a preferred embodiment of the present invention includes a cabinet 1, a door 2, and a hinge assembly 3. The structure of the hinge assembly 3 and the use process thereof will be described in detail below, wherein the case 1 and the door 2 are in the prior art. One of the hinge seat 31 and the hinge 32 is fixed with the box body 1, and the other is fixed with the door body 2.

As shown in fig. 1 to 9, the hinge assembly 3 according to a preferred embodiment of the present invention includes a hinge base 31, and a hinge 32 movably connected to the hinge base 31, and can be used for any furniture 100 requiring a rotary door 2 to be opened, such as a refrigerating apparatus. Normally, one of the hinge seat 31 and the hinge 32 is fixed to the case 1, and the other is fixed to the door 2, and the movement track of the hinge 32 is defined by the hinge seat 31 so as to drive the door 2 to move.

The hinge 32 includes a first hinge shaft 321 and a second hinge shaft 322 that are disposed at intervals, and the moving track of the hinge 32 relative to the hinge base 31 is defined by two axes, so that the running stability of the door body 2 in the door opening and closing process can be improved.

Specifically, the hinge 32 further includes a fixing portion 323 for fixing to the case 1 or the door 2, a moving portion 324 engaged with the hinge base 31, and a connecting portion 325 connecting the fixing portion 323 and the moving portion 324, the mounting portion has a fixing hole for fixing to the case 1 or the door 2, and the first hinge shaft 321 and the second hinge shaft 322 are disposed on the moving portion 324.

In a specific embodiment, the fixing portion 323 and the moving portion 324 are disposed in parallel, and the connecting portion 325 connects the rear end of the fixing portion 323 and the front end of the moving portion 324, and the first hinge shaft 321 and the second hinge shaft 322 are respectively located at the front end and the rear end of the moving portion 324, so that the whole hinge 32 has a compact and small structure, and the space required for moving the hinge 32 relative to the hinge seat 31 is small.

The hinge base 31 has a sliding slot defining a moving track of the first hinge shaft 321 and the second hinge shaft 322 so that the hinge 32 slides back and forth relative to the hinge base 31 and rotates back and forth; so that the furniture 100 provided with the hinge assembly 3 is provided, the door body 2 slides forward and then rotates when being opened, and the door body 2 rotates and then slides backward when being closed; and after the door body 2 moves forward, other furniture or walls beyond both sides of the furniture 100 in the front-rear direction can be prevented from colliding with them. Taking an embedded refrigerator embedded in a wall or other furniture as an example, the door body moves forwards and then rotates, so that the door body cannot collide with the walls or furniture on two sides of the refrigerator.

The sliding groove includes a first linear groove 311 guiding the first hinge shaft 321 to move in the front-rear direction, a second linear groove 312 guiding the second hinge 32 to move in the front-rear direction, and an arc groove 313 guiding the second hinge shaft 322 to move in an arc shape, wherein the arc groove 313 is communicated with the second linear groove 312. In the present invention, the arc-shaped groove 313 has an omega shape.

Further, the first linear groove 311 is located at the front side of the second linear groove 312, and the first linear groove 311 is communicated with the second linear groove 312; therefore, the first hinge shaft 321 is always located at the rear side of the connection between the arc slot 313 and the second line slot 312, so that the first hinge shaft 321 is prevented from entering the arc slot 313. Alternatively, in other embodiments, the first line slot 311 and the second line slot 312 may be separately configured, so as to achieve the corresponding effect.

The distance between the first hinge shaft 321 and the second hinge shaft 322, the length from the connection point between the arc slot 313 and the second linear slot 312 to the rear end of the second linear slot 312, and the length of the first linear slot 311 are identical, so that the hinge 32 does not rotate when moving in the front-rear direction relative to the hinge base 31.

In addition, the cross section of the first hinge shaft 321 cut along the plane parallel to the hinge seat 31 is rectangular-like, and the width of the first linear groove 311 is consistent with the width of the rectangular-like, so as to ensure that the hinge 32 stably moves along the front-rear direction relative to the hinge seat 31 without shaking; and the front end of the first linear groove 311 is circular, and the diameter of the circular shape is consistent with the length of the rectangle, so that the hinge 32 will not shake during the rotation process of the hinge base 31. It will be appreciated by those skilled in the art that the long and short sides of the rectangle may be straight or arc sides, and the long and short sides are connected by right angles or arc angles.

Further, the second hinge shaft 322 has a cylindrical shape, and the width of the second linear groove 312 and the width of the arc-shaped groove 313 are identical to the diameter of the second hinge shaft 322, thereby further ensuring the stable movement and rotation of the hinge 32. Wherein the diameter of the second hinge shaft 322 is the diameter of the second hinge shaft 322 in a cross section cut along a plane parallel to the hinge base 31.

Based on any one of the above hinge assemblies 3, the power-assisted reset assembly 33 further comprises a power-assisted reset assembly 33, wherein the power-assisted reset assembly 33 comprises a first connecting rod 331 rotationally connected with the hinge base 31, a second connecting rod 332 rotationally connected with the first connecting rod 331, and a torsion spring 333 connected between the first connecting rod 331 and the hinge base 31, and one end of the second connecting rod 332 away from the first connecting rod 331 is rotationally connected with the hinge 32. As the first link 331 rotates relative to the second link 332, a linear distance between an end of the first link 331 facing away from the second link 332 and an end of the second link 332 facing away from the first link 331 changes, and the range of the linear distance is set to ensure that the power-assisted reset assembly 33 does not fail no matter to which position or state the hinge 32 moves relative to the hinge base 31.

In the door opening process, the hinge 32 moves relative to the hinge seat 31 and pulls the torsion spring 333 to store force, and in the door closing process, the elastic restoring force of the torsion spring 333 pulls the first link 331 to rotate reversely, the first link 331 drives the second link 332 to rotate, and the second link 332 pulls the hinge 32 to reset, so as to play a role in assisting in closing the door, so that the assisting reset assembly 33 can be also referred to as an assisting door closing assembly.

Specifically, the hinge seat 31 further includes a fixing column 314, the torsion spring 333 is sleeved on the fixing column 314, one end of the first connecting rod 331 away from the second connecting rod 332 is rotatably connected with one end of the fixing column 314 away from the hinge seat 31, and two ends of the torsion spring 333 are respectively fixed with the hinge seat 31 and the first connecting rod 331. In the door opening process, the first connecting rod 331 rotates around the fixed column 314 along one direction, and pulls the torsion spring 333 to deform and store force; in the closing process, the torsion spring 333 returns to its original state and provides power for the hinge 32 to rotate reversely, so as to assist in closing the door, and even if the user releases his hand in the closing process, the door can be closed.

Further, the end of the second connecting rod 332 away from the first connecting rod 331 is rotatably connected with the second hinge shaft 322, without additionally providing a rotation shaft on the hinge 32, and the movement track of the end of the second connecting rod 332 away from the first connecting rod 331 is tracked, so that the straight line distance can be determined in a straight pipe.

In one embodiment, the fixing post 314 is located in an angle formed by the second linear slot 312 and the arc slot 313, and the overall length angles of the first link 331 and the second link 332 do not affect the movement of the hinge 32.

Further, the first link 331 includes a first bottom plate 3311, a first top plate 3312 spaced apart from the first bottom plate 3311, and a first rotation shaft 3313 connected between the first bottom plate 3311 and the first top plate 3312; the hinge 32 includes a second bottom plate 326, a second top plate 327 spaced from the second bottom plate 326, and a second rotating shaft connected between the second bottom plate 326 and the second top plate 327, and two ends of the second connecting rod 332 are respectively provided with a first hole 3321 sleeved on the first rotating shaft 3313 and a second hole 3322 sleeved on the second rotating shaft. Therefore, the second link 332 and the hinge seat 31 have a gap therebetween, that is, they are not in contact with each other, friction is not generated during the movement, and labor is saved during the door opening and closing process.

Further, the first link 331 further includes at least one supporting member located at the bottom of the first link 331, so as to reduce the contact area between the bottom of the first link 331 and the hinge base 31, and further reduce the friction force during opening and closing the door. In this embodiment, the first link 331 includes two supporting members disposed at intervals.

In addition, the hinge assembly 3 further includes a hinge cover 34 disposed at a side of the hinge 32 facing away from the hinge base 31, for protecting the hinge assembly and for aesthetic purposes. The hinge cover 34 is provided with an auxiliary chute 341 corresponding to the chute, i.e. the auxiliary chute 341 is vertically symmetrical with the chute; the hinge 32 further includes a first auxiliary shaft 329 and a second auxiliary shaft 320 moving along the auxiliary sliding groove 341, the first auxiliary shaft 329 being coaxial with the first hinge shaft 321, and the second auxiliary shaft 320 being coaxial with the second hinge shaft 322. The sliding grooves and the auxiliary sliding grooves are opposite to each other along the vertical direction to form a sliding way together, the moving track of the hinge 32 is limited from the two sides of the hinge 32, and the moving stability is improved.
