The rotation axis of the hinge structure is generally parallel to the horizontal plane, and the gravity of the door body 2 needs to be overcome when the storage chamber is opened by the door body; when the storage chamber is closed, the door body 2 rotates rapidly under the action of gravity to close the storage chamber. This application aims at reducing the rotational speed of the door body 2 when the door body 2 closes the storeroom, reduces the impact of the door body 2 to the box 1, promotes user's use and experiences.

According to the refrigerator provided by the embodiment of the invention, as shown in fig. 1 and 2, a refrigerator body 1 and a door body 2 are connected through a damping hinge 3, the damping hinge 3 comprises a first hinge seat 31 fixedly connected with the refrigerator body 1 and a second hinge seat 32 fixedly connected with the door body 2, wherein the first hinge seat 31 and the second hinge seat 32 are connected through a rotating shaft 33, the storage chamber is opened or closed in the process that the door body 2 rotates relative to the refrigerator body 1, referring to fig. 2 and 3, the damping hinge 3 further comprises a damper 34 and a pressing plate 35, the damper 34 is installed on the first hinge seat 31, the pressing plate 35 comprises a fixed part 351 and an abutting part 352, the pressing plate 35 is fixedly connected with the second hinge seat 32 through a fixed part 351, the abutting part 352 is of a cam structure, when a door body closing angle α is smaller than a certain threshold value in the process that the storage chamber of the door body 2 is closed, the abutting part 352 presses the damper 34, the damper 34 provides a damping force opposite to the door body 2 movement direction of the door body 2, referring to fig. 3 and fig. 4, the pressing plate 35 can be a damping force which is set to be opposite to the movement direction of the door body 2 when the door body 2 is closed, and the pressing force is set to be a damping force which is smaller than a damping force which is directly applied to a damping mechanism, and can be applied to a damping mechanism, the damping mechanism can be set to reduce the damping mechanism, and the damping mechanism of the damping mechanism, and the damping mechanism of the damping mechanism, and the damping mechanism can be more conveniently reduce the damping mechanism, the damping mechanism can.

Referring to fig. 4, the "door closing angle α" refers to an angle between the door 2 and the upper sidewall of the cabinet 1 when the door 2 closes the storage compartment 2, and at least two hinges are provided between the door 2 and the cabinet 1 when the door 2 is hinged to the cabinet 1.

When the door 2 closes the storage chamber, the pressing plate 35 rotates relative to the cabinet 1, and the damper 34 moves linearly relative to the cabinet. In the prior art, a pressure plate is not directly abutted against a damper, because if the pressure plate is directly abutted against the damper, relative sliding can be generated between the pressure plate and the damper on a contact surface of the pressure plate and the damper in the process of converting rotary motion into linear motion for pressing the damper, and a larger friction force can be generated between the pressure plate and the damper due to the larger pressure between the pressure plate and the damper, on one hand, the friction force can push the damper to swing in the direction of the friction force, so that the damper is inconvenient to mount and fix; on the other hand, the friction force can cause the abrasion between the pressure plate and the damper to be larger, and the pressure plate is easy to have structural failure after long-time use; therefore, it is necessary to provide a protrusion structure between the pressure plate and the damper for converting the rotation of the pressure plate into the linear motion of the damper.

In the refrigerator of the embodiment of the invention, the abutting part 352 is designed to be a cam structure, wherein an arc line of the cam structure close to one side of the damper 34 can be calculated in a finite element analysis mode. Referring to fig. 5 and 6, during the rotation of the abutting portion 352 around the rotation shaft 33, the abutting portion 352 rolls rather than slides with respect to the damper 34 at the contact surface between the abutting portion 352 and the damper 34, and there is no or little friction between the abutting portion 352 and the damper 34, so that the abutting portion 352 can directly abut against the damper 34 and press the damper 34, thereby reducing the number of used structural members. Meanwhile, the pressing plate 35 is generally made of a metal material, and has high structural reliability without deformation or structural failure.

In some embodiments, as shown in fig. 2, the abutting portion 352 is a plate-shaped structure, and in order to increase the structural strength of the abutting portion 352, as shown in fig. 3, a reinforcing flange 353 is provided at an edge of the abutting portion 352 contacting the damper 34, and the reinforcing flange 353 extends in a direction perpendicular to the abutting portion 352. Alternatively, as shown in fig. 3, the reinforcing flange 353 is formed by bending the side of the abutting portion 352 close to the damper 34 toward the second hinge base 32. The reinforcing flange 353 serves to increase the contact area between the abutting portion 352 and the damper 34, increasing the structural strength of the abutting portion 352. The reinforcing flange 353 can also increase the width of the side wall of the abutting portion 352 in contact with the damper 34, so that the requirement of the damping hinge 3 on the position accuracy of the pressure plate 35 and the damper 34 is reduced, even if a little installation error occurs in the positions of the pressure plate 35 and the damper 34, the abutting portion 352 can still be ensured to abut against the damper 34, and the installation difficulty of the damping hinge 3 is reduced.

It should be noted that the reinforcing flange 353 can be provided in other forms, for example, the reinforcing flange 353 can be formed by bending the side edge close to the damper 34 toward the side edge far away from the second hinge base 32; alternatively, the abutting portion 352 may be made of a plate material having a non-uniform thickness, wherein the thickness of the abutting portion 352 near the damper 34 is larger than that of the other portions; alternatively, the abutting portion 352 is directly made of a thick plate material as the base material of the pressing plate 35.

In some embodiments, as shown in fig. 2 and 3, the fixing portion 351 of the pressure plate 35 is perpendicular to the abutting portion 352, and optionally, the fixing portion 351 is of a plate-shaped structure, and the fixing portion 351 is attached to the side wall of the second hinge seat 32 close to the door body 2 and is riveted to the second hinge seat 32, and the fixing portion 351 is located between the second hinge seat 32 and the door body 2. The second hinge seat 32 is a C-shaped structure, and includes a first sidewall 321 attached to the door 2 and a second sidewall 322 perpendicular to the door 2, and the fixing portion 351 is a plate-shaped structure and is disposed between the first sidewall 321 and the door 2, so that not only the contact area between the fixing portion 351 and the second hinge seat 32 can be increased, but also the connection strength between the pressing plate 35 and the second hinge seat 31 can be increased. Meanwhile, the fixing portion 351 is clamped between the first sidewall 321 and the door body 2, and the damping force provided by the damper 34 received by the abutting portion 352 can be directly transmitted to the door body 2. Since the damper 34 is generally disposed at the side of the first hinge base 31, the abutting portion 352 is parallel to the second side wall 322 in order to facilitate the abutting portion 352 to press the damper 34. Optionally, the fixing portion 351 and the abutting portion 352 of the pressing plate 35 are an integral structure, and the pressing plate 35 is formed by bending a plate.

It should be understood that the rivet-fastening of the fastening portion 351 to the second hinge base 32 is only one preferred embodiment for fastening the pressing plate 35. Alternatively, the fixing portion 351 may be fixedly connected to the second hinge base 32 by welding or other connection methods.

In some embodiments, as shown in fig. 2 and 9, the first hinge base 31 includes a first side plate 31a attached to the case 1 and a second side plate 31b perpendicular to the first side plate 31 a; damper 34 is installed on the lateral wall of second side plate 31b, is equipped with mount table 311 on the lateral wall of second side plate 31b moreover, and one end that damper 34 kept away from butt portion 352 butts with mount table 311, promptly: as shown in fig. 7, the lower end of the damper 34 abuts against the upper side wall of the mount table 311. As shown in fig. 9, the first hinge base 31 generally includes a first side plate 31a and two second side plates 31b to form a C-shaped groove structure, which can reinforce the structural strength of the first hinge base 31 and prevent the damping hinge 3 from structural failure. The mount table 311 serves to restrict the damper 34 from moving in the vertical direction away from the abutting portion 352. When the abutting portion 352 presses the damper 34 downward, the lower end of the damper 34 does not move downward, ensuring that the damper 34 can elastically deform and provide a damping force to the platen 35. In the prior art, the damper is generally fixedly connected with the damper outer shell, then the damper outer shell is fixedly connected with the first hinge base, and further the damper is fixedly connected with the first hinge base, and downward pressure applied to the damper needs to be transmitted to the first hinge base through the damper outer shell. Compared with the prior art, the refrigerator according to the embodiment of the invention has the advantages that the downward pressure applied to the damper 34 is directly transmitted to the mounting table 311 through the lower end of the damper 34, the structure is simple, and the reliability is higher.

In some embodiments, as shown in fig. 3, the mounting table 311 is an integral structure with the first hinge base 31, and the mounting table 311 is cut and bent from the second side plate 31 b. Alternatively, the mounting platform 311 is perpendicular to the side wall of the first hinge base 31, and the mounting platform 311 is formed by cutting and bending the second side plate 31 b. The mounting table 311 is formed by cutting and bending the second side plate 31b, so that the material can be saved and the manufacturing cost can be reduced. The mounting table 311 may be formed separately, and then the mounting table 311 is fixedly coupled to the sidewall of the second side plate 31 b. Compared with a single processing mode, the freezer provided by the embodiment of the invention has the advantages that the mounting table 311 is formed by bending the side wall of the first hinge seat 31 outwards, the structure is simple, the installation is convenient, the material is saved, and the cost is lower.

Because the spring damper is reliable in construction and relatively low in cost, in some embodiments, the spring damper is selected as the damper 34. When the damper 34 is a spring damper, as shown in fig. 8, the freezer according to the embodiment of the present invention includes the damper 34: a base 341, an end of the base 341 extending upward to form a guide rod 3411; the top base 342 is provided with a guide hole 3421 matched with the guide rod 3411, the guide hole 3421 is sleeved outside the guide rod 3411, the top base 342 can slide along the extending direction of the guide rod 3411, the guide hole 3421 can be a blind hole or a through hole, and when the guide hole 3421 is a blind hole, the opening of the guide hole 3421 is positioned at the bottom of the top base 342; and the spring 343, the spring 343 is sleeved outside the guide rod 3411, and one end of the spring 343 abuts against the upper side wall of the base 341 and the other end abuts against the lower side wall of the top seat 342. Wherein, the guiding hole 3421 and the guiding rod 3411 are matched, which means: the diameter of the guide hole 3421 is slightly larger than the diameter of the guide rod 3411, so that the top seat 342 can slide along the guide rod 3411 without shaking in the radial direction of the guide rod 3411 under the guidance of the guide hole 3421. When the door 2 closes the storage chamber, the abutting portion 352 presses the top holder 342, and the top holder 342 compresses the spring 343 in the extending direction of the guide rod 3411; the spring 343 is elastically deformed and provides the top seat 342 with an elastic restoring force, which is transmitted to the abutting portion 352 through the top seat 342 to form a damping force.

It should be noted that other forms of damper may be selected for the damper 34, for example, a hydraulic damper or a viscous damper may be used. According to the refrigerator provided by the embodiment of the invention, the spring damper is selected, on one hand, the spring damper is simple in structure, high in reliability and low in cost; on the other hand, the damping force that spring damper provided for the door body 2 can be transformed into the power that convenience of customers opened the door when the storeroom was opened to user operation door body 2, and convenience of customers opens door body 2, promotes user's use and experiences.

Referring to fig. 3 and 5, the damping hinge 3 further includes a damper housing 36 and a driving plate 37. The damper housing 36 covers the side of the damper 34 remote from the second side plate 31b, and the damper housing 36 is fixedly attached to the second side plate 31 b. The damper housing 36 is used to restrict the movement of the damper 34 in a direction away from the second side plate 31b, and the damper housing 36 cooperates with the mounting table 311 to mount the damper 34 on the outer side wall of the second side plate 31 b. The abutting portion 352 presses the damper 34 through the transmission plate 37, the extending direction of the transmission plate 37 is parallel to the extending direction of the damper 34, the transmission plate 37 is movably arranged in the damper housing 36, one end, close to the abutting portion 352, of the transmission plate 37 extends out of the damper housing 36, the transmission plate 37 is provided with the installation groove 71, the extending direction of the installation groove 71 is parallel to the extending direction of the damper 34, the damper 34 is located in the installation groove 71, the top seat 342 abuts against the installation groove 71, and specifically, the upper side wall of the installation groove 71 abuts against the top wall of the top seat 342.

In the process of closing the storage chamber by the door 2, as shown in fig. 5 and 6, the abutting portion 352 abuts against the upper side wall of the transmission plate 37. The abutting portion 352 rotates on the one hand about the rotating shaft 33, and at the same time, the abutting portion 352 rolls on the upper side wall of the transmission plate 37 and presses the transmission plate 37 downward, and the cam structure converts the rotation of the abutting portion 352 about the rotating shaft 33 into the linear downward movement of the transmission plate 37 by the abutting portion 352 pressing the transmission plate 37. The transmission plate 37 presses the damper 34 downward, and since the lower end of the base 341 of the damper 34 abuts against the mounting plate 311, the spring 343 is compressed and generates an elastic restoring force. The elastic restoring force acts on the transmission plate 37 and is transmitted to the abutting portion 352 through the transmission plate 37, and then is transmitted to the door body 2 through the second hinge base 32 to form a damping force in a direction opposite to the moving direction of the door body 2. The damping force can reduce the rotating speed of the door body 2 when the door body 2 closes the storage chamber, further reduce the impact force of the door body 2 on the box body 1, reduce the noise when the door body 2 collides with the box body 1, reduce the impact of the door body 2 on the door seal and prolong the service life of the door seal.

The damping hinge 3 is disposed within the hinge cover 38. The hinge cover 38 prevents dust or other foreign materials from entering the hinge cover 38, and the hinge cover 38 protects the damper hinge 3.
