In the process from a door closing state to a door opening state, the refrigerator is provided with the hinge mechanism, and the limit part 310 of the hinge assembly 300 is matched with the limit matching part 410 of the hinge seat 400, so that the refrigerator door body 100 sequentially moves and rotates in a translational motion away from the direction of the refrigerator body 200 relative to the refrigerator body 200, the refrigerator door body 100 can completely avoid a use space in the refrigerator body 200 after being opened, the refrigerator door body does not interfere with a wall body near the side wall of the refrigerator body 200, and a drawer in the refrigerator body 200 can be easily used by a user after the refrigerator door body 100 is opened.

Alternatively, as shown in fig. 1 to 5, after the refrigerator door 100 in this embodiment is opened, the door 100 is still 90 ° relative to the opening angle of the refrigerator body 200 by matching the limiting portion 310 of the hinge assembly 300 with the limiting matching portion 410 of the hinge base 400, and the hinge mechanism provided in this embodiment makes the refrigerator door 100 located outside the side wall of the refrigerator body 200 after opening, so that the mutual overlapping interference between the refrigerator door 100 and the side wall of the refrigerator body 200 is avoided, the internal space of the refrigerator body 200 is not affected for a user, and the use of the drawer inside the refrigerator body 200 is more facilitated.

Alternatively, as shown in fig. 1 to 8, in the process of the refrigerator from the door closing state to the door opening state, the refrigerator door 100 is moved in a translational motion away from the case 200 with respect to the case 200 by the cooperation of the limiting portion 310 of the hinge assembly 300 and the limiting engaging portion 410 of the hinge base 400, and then the refrigerator door 100 is rotated with respect to the case 200 by the cooperation of the limiting portion 310 of the hinge assembly 300 and the limiting engaging portion 410 of the hinge base 400. The setting makes refrigerator door 100 first for box 200 translational motion, rotates again and opens, makes door 100 be located the outside of box 200 lateral wall after opening, and the door 100 can dodge the usage space in the box 200 completely promptly, and door 100 is 90 for box 200 opening angle to do not interfere with the wall body near the box 200 lateral wall, the drawer in the easy use refrigerator box 200 of user of being convenient for makes the drawer can freely take out or impel the box 200 of refrigerator, improves user's use experience to the refrigerator.

Alternatively, as shown in fig. 1 to 8, the hinge assembly 300 includes a hinge 320 and a rotating member 330, wherein the hinge 320 is adapted to be connected to the door body 100, and a first stopper 311 is provided; the rotating piece 330 is movably connected with the hinge 320 and is provided with a second limiting part 312; the first limiting portion 311 is matched with the limiting matching portion 410, and the second limiting portion 312 is matched with the limiting matching portion 410 to guide the hinge assembly 300 to sequentially perform translational movement and rotation relative to the hinge base 400 in a direction away from the hinge base 400, wherein the limiting portion 310 includes the first limiting portion 311 and the second limiting portion 312.

For example, the first limiting portion 311 of the hinge 320 can cooperate with the limiting engagement portion 410 to guide the hinge assembly 300 to perform a translational movement relative to the hinge base 400 in a direction away from the hinge base 400. The second limiting portion 312 of the rotating member 330 is engaged with the limiting engaging portion 410, and the hinge assembly 300 is guided to rotate relative to the hinge base 400 due to the movable connection of the rotating member 330 and the hinge 320.

For example, the hinge 320 is provided with a through mounting hole, the rotating member 330 is disposed through the mounting hole, that is, the rotating member 330 is rotationally connected with the hinge 320 through the mounting hole, and after the rotating member 330 passes through the mounting hole, a portion beyond the mounting hole is set as the second limiting portion 312, so that the second limiting portion 312 is matched with the limiting matching portion 410. In this way, the rotating member 330 is rotationally connected with the hinge 320, and when the rotating member 330 rotates, the rotating member 330 drives the hinge 320 to move, so that the first limiting portion 311 and the second limiting portion 312 can both cooperate with the limiting cooperation portion 410, so as to guide the hinge assembly 300 to sequentially perform translational movement and rotation relative to the hinge base 400 in a direction away from the hinge base 400.

Optionally, as shown in fig. 1, 2 and 9, a second hinge assembly and a second hinge mount are further provided in the height direction of the refrigerator door 100. Likewise, the second hinge assembly includes a second hinge and a rotator 330. Wherein, the second hinge is provided with a third limiting portion, and the rotating member 330 is provided with a fourth limiting portion.

For example, the second hinge is adapted to be connected to the door body 100, and the second hinge is provided with a third limiting portion; the rotating piece 330 is movably connected with the second hinge, and the rotating piece 330 is provided with a fourth limiting part; the second hinge seat is provided with a second limit matching part, the third limit part is matched with the second limit matching part, and the fourth limit part is matched with the second limit matching part so as to guide the second hinge assembly to sequentially perform translational movement and rotation in a direction away from the second hinge seat relative to the second hinge seat. Because the rotating member 330 is movably connected to the hinge 320 and the second hinge, when the rotating member 330 rotates, the rotating member 330 drives the hinge 320 and the second hinge to move synchronously, so that the first limiting portion 311 and the second limiting portion 312 can both cooperate with the limiting cooperation portion 410 to guide the hinge assembly 300 to sequentially perform a translational movement and a rotation relative to the hinge base 400 in a direction away from the hinge base 400. Meanwhile, the rotating piece 330 also enables the third limiting portion and the fourth limiting portion to be matched with the second limiting matching portion, so as to guide the second hinge assembly to sequentially perform translational movement and rotation in a direction away from the second hinge seat relative to the second hinge seat. The arrangement is such that the hinge assembly 300 and the second hinge assembly, which are disposed along the height direction of the door body 100, move synchronously in the opening process of the refrigerator door body 100, so as to drive the refrigerator door body 100 to move in a translational manner along the direction away from the refrigerator body 200, and then rotate relative to the refrigerator body 200, so as to increase the smoothness of the refrigerator door body 100 in the opening process.

Alternatively, as shown in fig. 4 to 8, the first and second stopper portions 311 and 312 include first and second stopper protrusions 321 and 331, respectively; the limit fitting portion 410 includes a limit groove 420, and the limit groove 420 includes: a linear slot segment 421; a curved slot section 422 located at one side of the straight slot section 421 and communicating with the straight slot section 421; in the initial state, the first limiting protrusion 321 and the second limiting protrusion 331 are both located in the linear groove section 421. Under the driving of the external force, the first limiting protrusion 321 slides relative to the linear slot section 421, so that the hinge assembly 300 moves in a translational motion relative to the hinge base 400 in a direction away from the hinge base 400, and the second limiting protrusion 331 slides into the curved slot section 422 through the linear slot section 421, so that the hinge assembly 300 rotates relative to the hinge base 400.

Alternatively, as shown in fig. 4 to 8, the first limiting portion 311 is a first limiting protrusion 321, the second limiting portion 312 is a second limiting protrusion 331, the limiting groove 420 includes a linear groove section 421 and a curved groove section 422, the linear groove section 421 and the curved groove section 422 are communicated, and the curved groove section 422 is communicated with the linear groove section 421 at a middle position of the linear groove section 421. In the initial state, the first limiting protrusion 321 and the second limiting protrusion 331 are both in the linear slot section 421, and under the driving of an external force, the first limiting protrusion 321 and the second limiting protrusion 331 slide along the linear slot section 421, so that the hinge assembly 300 performs a translational motion along a direction away from the hinge base 400. Then, the second limiting protrusion 331 slides into the curved slot section 422 from the connection between the linear slot section 421 and the curved slot section 422, so that the hinge assembly 300 rotates relative to the hinge base 400.

Alternatively, as shown in fig. 4 to 8, in the initial state, the second limiting protrusion 331 and the first limiting protrusion 321 are sequentially disposed in the linear slot section 421 along the translational motion direction, and when the first limiting protrusion 321 is located at the first end 600 of the linear slot section and abuts against the slot wall of the first end 600 of the linear slot section, the second limiting protrusion 331 slides to the communicating position of the linear slot section 421 and the curved slot section 422.

The second limiting protrusion 331 and the first limiting protrusion 321 in the refrigerator in the door closing state are sequentially arranged in the linear groove section 421 along the translational movement direction, that is, the first limiting protrusion 321 is closer to the door body 100 of the refrigerator than the second limiting protrusion 331.

For example, in the case that the first limiting protrusion 321 and the second limiting protrusion 331 move in a translational manner in a direction away from the refrigerator body 200 of the refrigerator, the first limiting protrusion 321 abuts against the groove wall of the first end 600 of the straight groove section in preference to the second limiting protrusion 331, and at this time, the second limiting protrusion 331 is located at a communication position between the straight groove section 421 and the curved groove section 422. The groove wall of the first end 600 of the linear groove section is abutted against the first limiting protrusion 321 so as to limit the stopping position of the first limiting protrusion 321 along the translational movement away from the case 200. The distance between the first limiting protrusion 321 and the second limiting protrusion 331 along the direction of the linear groove section 421 is fixed, so that the distance between the first limiting protrusion 321 and the second limiting protrusion 331 along the direction of the linear groove section 421 is a fixed value. By the arrangement, under the condition that the first limiting protrusion 321 is abutted against the first end 600 of the linear groove section, the second limiting protrusion 331 is guaranteed to be located at the communication position of the linear groove section 421 and the curved groove section 422, so that the door body 100 of the refrigerator translates for a distance along the direction away from the refrigerator body 200 relative to the refrigerator body 200, the door body 100 of the refrigerator is guaranteed to be located outside the side wall of the refrigerator body 200 after the door body 100 of the refrigerator rotates, the door body 100 does not interfere with a wall body near the side wall of the refrigerator body 200, and the use space of the door body 100 of the refrigerator door in the refrigerator body 200 is fully avoided.

Alternatively, as shown in fig. 4 to 8, in the initial state, the second limiting protrusion 331 is located at the second end 700 of the linear slot segment and abuts against the slot wall of the second end 700 of the linear slot segment.

In the initial state, the second limiting protrusion 331 is located at the second end 70 of the linear slot segment and abuts against the slot wall of the second end 700 of the linear slot segment. By the arrangement, the second end 700 of the linear groove section limits the translational movement of the second limiting protrusion 331 along the direction close to the refrigerator body 200 when the refrigerator is in a door closing state, so that the refrigerator can accurately reach the door closing state, and the reliability of the refrigerator hinge mechanism is guaranteed when the refrigerator is in the door closing state.

For example, the drive member 520 may be a motor that is drivingly connected to the rotating assembly 510. The rotating assembly 510 further includes a driving gear 513 and a driven gear 514, wherein the driving gear 513 meshes with the driven gear 514. The driving gear 513 is connected to a motor, and the driven gear 514 is connected to the rotating member 330. When the motor starts to rotate, the motor drives the driving gear 513 to rotate, the driving gear 513 drives the driven gear 514, and the driven gear 514 drives the rotating member 330 to rotate, so as to provide driving force for the rotating member 330. By the arrangement, the hinge mechanism in the embodiment can electrically open the refrigerator door 100 by using the driving force provided by the driving assembly 500, so that the convenience of using the refrigerator is improved.

Similarly, when the rotation direction of the motor is opposite to the opening direction of the refrigerator door 100, the refrigerator door 100 can be electrically closed by driving the hinge mechanism for the refrigerator in the embodiment through the motor, thereby facilitating the use of the refrigerator by a user. In other words, the hinge mechanism for a refrigerator in the present embodiment can electrically open or electrically close the door body 100 through the driving member 520, thereby providing convenience to a user in using the refrigerator.

Alternatively, as shown in fig. 1 to 5, the rotation assembly 510 includes a first rotation member 511 and a second rotation member 512. One end of the first rotating member 511 is rotatably connected to the rotating member 330; one end of the second rotating member 512 is rotatably connected to the other end of the first rotating member 511, and the driving member 520 is drivingly connected to the other end of the second rotating member 512, for driving the second rotating member 512 to rotate.

For example, two ends of the first rotating member 511 are respectively connected to the rotating member 330 and the second rotating member 512, and two ends of the second rotating member 512 are respectively connected to the driving member 520 and the first rotating member 511, so that the driving member 520 provides driving force to drive the second rotating member 512 to rotate, so that the second rotating member 512 drives the first rotating member 511 to rotate, and then the first rotating member 511 drives the rotating member 330 to rotate.

For example, the first rotating member 511 and the second rotating member 512 are connected by a pin, so that the second rotating member 512 can drive the first rotating member 511 to rotate when the second rotating member 512 rotates. The first rotating member 511 is provided with a through hole, the inner wall surface of the through hole is a first gear surface, and a second gear surface is provided on the rotating member 330 at a portion connected with the first rotating member 511, and the first gear surface is meshed with the second gear surface, so that the first rotating member 511 can drive the rotating member 330 to rotate. The driving member 520 drives the second rotating member 512 through a transmission gear, and the second rotating member 512 is provided with a gear hole meshed with the transmission gear, and the transmission gear is meshed with the gear hole, so that the driving member 520 can drive the second rotating member 512 to rotate through the transmission gear. The arrangement is such that the driving member 520 drives the second rotating member 512 to rotate, the second rotating member 512 drives the first rotating member 511 to rotate, and the first rotating member 511 drives the rotating member 330 to move.

The movement process of the hinge mechanism for a refrigerator in the present embodiment will be described with reference to fig. 1 to 10.

When the refrigerator is in a door-closed state, the second limiting protrusion 331 of the rotating member 330 abuts against the groove wall of the second end 700 of the linear groove section of the hinge base 400.

In the process of the refrigerator from a door closing state to a door opening state, the motor starts to drive the driving gear 513 to rotate, the driving gear 513 drives the driven gear 514, the driven gear 514 drives the second rotating member 512 to rotate, the second rotating member 512 drives the first rotating member 511 to rotate, the first rotating member 511 drives the rotating member 330 to move, because the second limiting protrusion 331 of the rotating member 330 is located in the linear groove section 421, the second limiting protrusion 331 of the rotating member 330 moves in the linear groove section 421 in a direction away from the refrigerator box 200, the rotating member 330 is movably connected with the hinge 320, driving force is transmitted to the hinge 320, the first limiting protrusion 321 of the hinge 320 also moves in the linear groove section 421 in a direction away from the refrigerator box 200, the first limiting protrusion 321 moves to the first end 600 of the linear groove section and abuts against the groove wall of the first end 600 of the linear groove section, and at the moment, the second limiting protrusion 331 moves to the communication position of the linear groove section 421 and the curve groove section 422. Since the hinge 320 is connected to the door body 100, the refrigerator door body 100 is translated a distance in a direction away from the refrigerator body 200 after the above-described movement process, so as to increase the distance between the door body 100 and the refrigerator body 200.

The motor continues to rotate to provide driving force, the second limiting protrusion 331 moves along the curved slot section 422, so that the hinge 320 rotates relative to the hinge base 400, and when the second limiting protrusion 331 abuts against the slot wall at the end of the curved slot section 422, at this time, the movement process of opening the door is finished, and the door body 100 is in an open state relative to the box body 200.

Because the door body 100 translates a distance along the direction away from the box body 200 relative to the box body 200, the distance between the door body 100 and the box body 200 is increased, so that after the door body 100 rotates and opens, the door body 100 is positioned on the outer side of the side wall of the box body 200, and the door body 100 does not interfere with the side wall of the box body 200 or the wall near the box body 200, so that a user can easily use the drawer in the refrigerator.

The movement process of the hinge mechanism for the refrigerator in this embodiment from the door-open state to the door-closed state is similar to the above-described process, and will not be repeated here.

The refrigerator provided by the embodiment comprises a door body 100 and a refrigerator body 200; the hinge mechanism for a refrigerator according to any one of the above embodiments has all the advantageous effects of the hinge mechanism for a refrigerator according to any one of the above embodiments, and will not be described in detail herein.

Alternatively, as shown in fig. 1, 2, 3 and 8, the case 200 defines a receiving chamber 210, a chamber wall of the receiving chamber 210 is provided with a mounting groove 211, and the hinge mount 400 is positioned in the mounting groove 211.

The cabinet 200 of the refrigerator defines a receiving chamber 210, and a wall of the receiving chamber 210 is provided with a mounting groove 211 such that the hinge mount 400 is disposed in the receiving chamber 210. In this way, the hinge base 400 of the refrigerator is hidden inside the refrigerator body 200 of the refrigerator, so that the overall appearance of the refrigerator is more concise and attractive.

For example, the hinge base 400 is bolted to the mounting groove 211, ensuring stability of the hinge base 400 during opening and closing of the refrigerator door. The bolted connection is a detachable connection, facilitating replacement and repair after long-term use of the hinge base 400.

Alternatively, as shown in fig. 2, 3 and 9, the mounting groove 211 is provided at the top wall of the accommodating chamber 210, and the side wall of the accommodating chamber 210 is provided with the escape groove 212 for escaping the rotary 330.

The inner wall of the accommodating chamber 210 of the refrigerator case 200 is provided with the mounting groove 211 for mounting the hinge seat 400 and the avoidance groove 212 for avoiding the rotary member 330, wherein the mounting groove 211 and the avoidance groove 212 are respectively formed in the top chamber wall and the side chamber wall of the accommodating chamber 210, so that the hinge mechanism is hidden inside the refrigerator case 200. The arrangement not only satisfies the practicability that the user can use the refrigerator drawer after the door body 100 of the refrigerator is opened, but also enables the hinge mechanism to be hidden in the refrigerator, so that the whole refrigerator is more attractive.

Alternatively, as shown in fig. 2 to 5, the refrigerator in the present embodiment may be a main and sub door refrigerator.
