Referring to fig. 1, in general, a refrigerator has an approximately rectangular parallelepiped shape, including a cabinet 1 and a door 2, the door 2 is movably connected with the cabinet 1, and the door 2 can open or close a storage compartment during movement of the door 2 with respect to the cabinet 1. The door body 2 of part of the refrigerator is connected with the box body 1 through a hinge structure, and the storage chamber is opened or closed in the rotation process of the door body 2. The rotation axis of the hinge structure is generally parallel to the horizontal plane, and the gravity of the door body needs to be overcome when the door body 2 opens the storage room; when the storage chamber is closed, the door body 2 is rotated rapidly to close the storage chamber under the action of gravity. The application aims to reduce the rotation speed of the door body 2 when the door body 2 closes the storage room, reduce the impact of the door body 2 on the box body 1 and improve the use experience of a user.
The embodiment of the invention provides a refrigerator, referring to fig. 1, the refrigerator comprises a box body 1, wherein a storage chamber is formed in the box body 1; the door body 2, the door body 2 is connected with the box body 1 through the damping hinge 3; referring to fig. 2 and 3, the damping hinge 3 includes: the first hinge seat 31, the first hinge seat 31 is fixedly connected with the box body 1; the second hinge base 32, the second hinge base 32 is fixedly connected with the door body 2, and the first hinge base 31 is connected with the second hinge base 32 through a rotating shaft 33; a damper 34, the damper 34 being mounted on the first hinge base 31; the pressing plate 35, the pressing plate 35 comprises a fixing part 351 and an abutting part 352, the fixing part 351 is fixedly connected with the second hinge base 32, and the abutting part 352 is of a cam structure; referring to fig. 4, 5 and 6, when the door body 2 closes the storage compartment and the door body closing angle α is smaller than a certain threshold value, the abutting portion 352 presses the damper 34, and the damper 34 provides a damping force to the door body 2 in a direction opposite to the moving direction of the door body 2.
As shown in fig. 1 and 2, a refrigerator provided in an embodiment of the present invention is characterized in that a case 1 is connected to a door 2 through a damping hinge 3, the damping hinge 3 includes a first hinge base 31 fixedly connected to the case 1, and a second hinge base 32 fixedly connected to the door 2, wherein the first hinge base 31 is connected to the second hinge base 32 through a rotation shaft 33, and the door 2 opens or closes a storage chamber during rotation of the door 2 relative to the case 1. Referring to fig. 2 and 3, the damping hinge 3 further includes a damper 34 and a pressing plate 35, the damper 34 is mounted on the first hinge seat 31, the pressing plate 35 includes a fixing portion 351 and an abutting portion 352, the pressing plate 35 is fixedly connected with the second hinge seat 32 through the fixing portion 351, the abutting portion 352 is of a cam structure, when the door body 2 closes the storage compartment, and the door body closing angle α is smaller than a certain threshold value, the abutting portion 352 presses the damper 34, and the damper 34 provides a damping force for the door body 2 in a direction opposite to the moving direction of the door body 2. Referring to fig. 3 and 4, in the process of closing the storage chamber by the door body 2, the door body 2 drives the pressing plate 35 to rotate around the rotating shaft 33, when the door body closing angle α is smaller than a certain threshold value, the abutting portion 352 abuts against the damper 34 and presses the damper 34, and the damper 34 provides a damping force for the door body 2 in a direction opposite to the door body movement direction through the abutting portion 352, so that the purpose of reducing the speed of closing the storage chamber by the door body 2 is achieved. In the embodiment of the present invention, referring to fig. 5 and 6, the abutting portion 352 is provided with a cam structure, which can directly convert the rotational movement transmission of the abutting portion 352 about the rotation shaft 33 into the linear movement of the abutting portion 352 pressing the damper 34. Compared with the prior art, the rotary motion of the door body is converted into the linear motion of the damper by utilizing the combined action of the pressing plate and the protruding structure. The refrigerator of the embodiment of the invention adopts the abutting part 352 as the cam structure, and the rotating motion of the abutting part 352 can be directly transferred into the linear motion for pressing the damper 34 through the cam structure, so that the abutting part 352 of the pressing plate 35 can directly press and drive the damper 34 without arranging a special adapter (a convex structure in the prior art), and the use of parts can be reduced on the premise of not influencing the function of the damping hinge 3 and the performance of the refrigerator, thereby simplifying the structure of the damping hinge 3 and facilitating the installation and reducing the cost of the refrigerator.
Referring to fig. 4, the "door closing angle α" means: the door body 2 is at an angle to the upper side wall of the case 1 in the process of closing the storage chamber 2. When the door body 2 is hinged with the box body 1, at least two hinges are arranged between the door body 2 and the box body 1.
In the process of closing the storage chamber by the door body 2, the pressing plate 35 rotates relative to the case 1, and the damper 34 moves linearly relative to the case. In the prior art, the pressing plate is not directly abutted against the damper, because if the pressing plate is directly abutted against the damper, in the process that the pressing plate converts rotary motion into linear motion for pressing the damper, relative sliding can be generated between the pressing plate and the damper on the contact surface of the pressing plate and the damper, and because larger pressure exists between the pressing plate and the damper, larger friction force can be generated between the pressing plate and the damper, on one hand, the friction force can push the damper to swing along the direction of the friction force, so that the installation and the fixation of the damper are inconvenient; on the other hand, the friction force can cause larger abrasion between the pressing plate and the damper, and the pressing plate is easy to generate structural failure after long-time use; therefore, it is necessary to provide a protrusion structure between the pressing plate and the damper for converting the rotation of the pressing plate into the linear motion of the damper.
The refrigerator according to the embodiment of the present invention designs the abutment 352 as a cam structure, wherein the arc of the cam structure near the damper 34 side can be calculated by finite element analysis. Referring to fig. 5 and 6, during rotation of the abutment 352 about the rotation axis 33, the abutment 352 rolls rather than slides relative to the damper 34 on the contact surface of the abutment 352 and the damper 34, and there is no or little friction between the abutment 352 and the damper 34, so that the abutment 352 can directly abut against the damper 34 and press the damper 34, thereby reducing the number of structural members. Meanwhile, the pressing plate 35 is usually made of a metal material, so that the structural reliability is high, and deformation or structural failure cannot occur.
In some embodiments, as shown in fig. 2, the abutting portion 352 has a plate-like 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 the edge of the abutting portion 352 that contacts the damper 34, the reinforcing flange 353 extending 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 edge of the abutment 352 adjacent to the damper 34 in a direction approaching the second hinge base 32. The reinforcing flange 353 serves to increase the contact area between the abutment 352 and the damper 34, and to increase the structural strength of the abutment 352. The reinforcing flange 353 can also increase the width of the side wall of the abutting portion 352, which is in contact with the damper 34, so that the requirement of the damping hinge 3 on the position accuracy of the pressing plate 35 and the damper 34 is reduced, and even if a point installation error occurs in the positions of the pressing 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 may be provided in other forms, for example, the reinforcing flange 353 may be formed by bending a side edge near the damper 34 toward a side edge far from the second hinge base 32; or the abutting portion 352 may be made of a plate material having a non-uniform thickness, wherein a portion of the abutting portion 352 near the damper 34 has a thickness greater than that of the other portion; or the abutment portion 352 directly adopts a thicker 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 pressing plate 35 is perpendicular to the abutting portion 352, alternatively, the fixing portion 351 is in a plate structure, and the fixing portion 351 is attached to the side wall of the second hinge base 32 near the door body 2 and is riveted to the second hinge base 32, and the fixing portion 351 is located between the second hinge base 32 and the door body 2. The second hinge base 32 is a C-shaped structure, and includes a first side wall 321 attached to the door body 2 and a second side wall 322 perpendicular to the door body 2, and the fixing portion 351 is configured as a plate-shaped structure and is disposed between the first side wall 321 and the door body 2, so that not only can the contact area between the fixing portion 351 and the second hinge base 32 be increased, but also the connection strength between the pressing plate 35 and the second hinge base 31 can be increased. At the same time, the fixing portion 351 is clamped between the first side wall 321 and the door 2, and the damping force provided by the damper 34 received by the abutting portion 352 can be directly transmitted to the door 2. Since the damper 34 is generally disposed at a side of the first hinge base 31, the abutting portion 352 is parallel to the second sidewall 322 for convenience in pressing the damper 34 against the abutting portion 352. Alternatively, the fixing portion 351 and the abutting portion 352 of the pressing plate 35 are integrally formed, and the pressing plate 35 is formed by bending a plate.
It should be understood that the rivet fixing of the fixing portion 351 to the second hinge base 32 is only a preferred embodiment of the fixing pressing plate 35. Alternatively, the fixing portion 351 may be fixedly connected to the second hinge base 32 by welding or other connection means.
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; the damper 34 is mounted on the outer side wall of the second side plate 31b, and the outer side wall of the second side plate 31b is provided with a mounting table 311, and one end of the damper 34 away from the abutting portion 352 abuts against the mounting table 311, namely: as shown in fig. 7, the lower end of the damper 34 abuts against the upper side wall of the mount 311. As shown in fig. 9, the first hinge base 31 is generally formed of a first side plate 31a and two second side plates 31b to form a C-shaped groove structure, and the C-shaped groove structure can strengthen the structural strength of the first hinge base 31 and prevent the damping hinge 3 from being structurally failed. The mount 311 serves to restrict the damper 34 from moving in the vertical direction in a direction away from the abutment 352. When the abutting portion 352 presses down the damper 34, 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 pressing plate 35. In the prior art, the damper is fixedly connected with the damper shell, then the damper shell is fixedly connected with the first hinge seat, and further the damper is fixedly connected with the first hinge seat, so that downward pressure applied to the damper needs to be transmitted to the first hinge seat through the damper shell. Compared with the prior art, the refrigerator of the embodiment of the invention has the advantages that the downward pressure born by 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 stand 311 and the first hinge base 31 are integrally formed, and the mounting stand 311 is formed by cutting and bending the second side plate 31 b. Alternatively, the mounting stand 311 is perpendicular to the side wall of the first hinge base 31, and the mounting stand 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 materials can be saved, and manufacturing cost can be reduced. The mounting table 311 may be formed separately, and then the mounting table 311 is fixedly attached to the side wall of the second side plate 31 b. Compared with a single processing mode, the refrigerator provided by the embodiment of the invention has the advantages that the mounting table 311 is formed by outwards bending the side wall of the first hinge seat 31, the structure is simple, the mounting is convenient, the material is saved, and the cost is lower.
Because spring dampers are structurally reliable and relatively low cost, in some embodiments, damper 34 is selected as the spring damper. When the damper 34 is a spring damper, as shown in fig. 8, the refrigerator according to the embodiment of the present invention, the damper 34 includes: a base 341, an end of the base 341 extending upward to form a guide bar 3411; the top seat 342, the top seat 342 is provided with a guide hole 3421 matched with the guide rod 3411, the guide hole 3421 is sleeved on the outer side of the guide rod 3411, the top seat 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 seat 342; the spring 343 is sleeved outside the guide rod 3411, one end of the spring 343 is abutted against the upper side wall of the base 341, and the other end is abutted against the lower side wall of the top seat 342. Wherein, the matching of the guide hole 3421 and the guide rod 3411 means: the diameter of the guide hole 3421 is slightly larger than that of the guide rod 3411, so that the top seat 342 can slide along the guide rod 3411 without shaking along the radial direction of the guide rod 3411 under the guide of the guide hole 3421. In the process of closing the storage chamber by the door body 2, the abutting part 352 presses the top seat 342, and the top seat 342 compresses the spring 343 along the extending direction of the guide bar 3411; the spring 343 is elastically deformed and provides an elastic restoring force to the top base 342, which is transmitted to the abutting portion 352 through the top base 342 to form a damping force.
It should be noted that other types of dampers may be selected for the damper 34, for example, a hydraulic damper, a viscous damper, or the like may be used. The refrigerator provided by the embodiment of the invention selects the spring damper, on one hand, the spring damper has the advantages of simple structure, high reliability and lower cost; on the other hand, the damping force provided by the spring damper for the door body 2 can be converted into power which is convenient for a user to open the door when the user operates the door body 2 to open the storage room, so that the user can conveniently open the door body 2, and the use experience of the user is improved.
Referring to fig. 3 and 5, the damped hinge 3 further includes a damper housing 36 and a drive plate 37. The damper housing 36 covers a side of the damper 34 away from the second side plate 31b, and the damper housing 36 is fixedly connected to the second side plate 31 b. The damper housing 36 serves 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 stand 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 driving plate 37, the extending direction of the driving plate 37 is parallel to the extending direction of the damper 34, the driving plate 37 is movably arranged in the damper housing 36, one end, close to the abutting portion 352, of the driving plate 37 extends out of the damper housing 36, the driving plate 37 is provided with a mounting groove 71, the extending direction of the mounting groove 71 is parallel to the extending direction of the damper 34, the damper 34 is located in the mounting groove 71, the top seat 342 abuts against the mounting groove 71, and specifically, the upper side wall of the mounting groove 71 abuts against the top wall of the top seat 342.
During the closing of the storage compartment by the door body 2, as shown in fig. 5 and 6, the abutment portion 352 abuts against the upper side wall of the drive plate 37. The abutment 352 rotates about the rotation shaft 33 on the one hand, and at the same time, the abutment 352 rolls on the upper side wall of the drive plate 37 and presses the drive plate 37 downward, the cam structure converts the rotation of the abutment 352 about the rotation shaft 33 into a movement of the abutment 352 pressing the drive plate 37 in a straight line downward. 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 driving plate 37 and is transmitted to the abutting portion 352 through the driving plate 37, and is then 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 rotation speed of the door body 2 when the door body 2 closes the storage room, so as to 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.
In some embodiments, as shown in fig. 3 and 9, a rivet 361 is disposed on a side of the damper housing 36 near the second side plate 31b, a receptacle 312 corresponding to the rivet 361 is disposed on the second side plate 31b, and the rivet 361 is inserted into the receptacle 312 to be riveted with the second side plate 31 b. As shown in fig. 3, the number of the rivet studs 361 is four, and the four rivet studs 361 are respectively located at two vertically extending sides of the damper housing 36. It should be appreciated that the damper housing 36 may also be fixedly coupled to the second side plate 31b by other means of fixation, such as welding or bolting.
Referring to fig. 1, the refrigerator according to the embodiment of the present invention further includes a hinge cover 38, the hinge cover 38 including a first hinge cover fixedly coupled with the first hinge base 31 and a second hinge cover fixedly coupled with the second hinge base 32, the first hinge cover being rotatably coupled with the second hinge cover; so that the first hinge cover and the second hinge cover can rotate relatively when the first hinge base 31 rotates relative to the second hinge base 32. The damping hinge 3 is arranged in a hinge cover 38. The hinge cover 38 prevents dust or other foreign matter from entering the hinge cover 38, and the hinge cover 38 serves to protect the damper hinge 3.
As shown in fig. 3 and 4, the damping hinge 3 of the refrigerator according to the embodiment of the invention is provided with a hovering mechanism 39, and when the door body 2 is opened within a preset angle range, the hovering mechanism 39 can make the door body 2 in a hovering state. Optionally, the hovering mechanism 39 is disposed inside the first hinge seat 31, and the hovering angle of the door body 2 ranges from 40 ° to 75 °, so as to facilitate the user to access the article. In this angular range, the weight of the door body 2 is equal to the supporting force provided by the hover mechanism 39 to the door body 2, and the door body 2 does not accelerate the closing speed of the storage compartment under the action of the weight. Therefore, in this angle range, the damper 34 is not required to provide a damping force to the door body 2, and the door body 2 is accelerated to fall under the action of gravity only when the gravity component of the door body 2 is greater than the supporting force of the hover mechanism 39 when the door body closing angle α is smaller than a certain threshold value. In order to reduce the influence of the gravity of the door 2 on the speed at which the door 2 closes the storage compartment, it is necessary to provide a damping force to the door 2. Therefore, when the door closing angle α is smaller than a certain threshold value during the closing of the storage compartment by the door 2, the abutting portion 352 starts to abut against and press the damper 34, and the damper 34 provides a damping force to the door 2 in a direction opposite to the moving direction of the door 2. Optionally, the threshold value range of the door body closing angle alpha is 25-35 degrees. Preferably, the door closing angle α threshold is 30 °, i.e., when the door closing angle α is less than 30 °, the abutting portion 352 comes into contact with the transmission plate 37 and presses the damper 34, and at this time, the damper 34 starts to provide the damping force to the door 2. If the threshold value of the door closing angle α is set too large, the deformation amount of the spring 343 will be too large, and the volume of the damper 34 will be large, which is inconvenient for installation and fixation of the damper 34. If the threshold value of the door closing angle α is set too small, the effect of the damping force generated by the damper 34 to reduce the speed of closing the storage chamber by the door is not obvious, and therefore, in the embodiment of the present invention, the threshold value is preferably 30 °.
As shown in fig. 1, the refrigerator according to the embodiment of the invention is characterized in that the door body 2 and the box body 1 are connected by two hinges. Alternatively, in order to reduce costs, one of the two hinges uses a damped hinge 3, the other being a normal hinge. The damping hinge 3 provided by the embodiment of the invention can be applied to other structures with hinged connection forms besides a refrigerator, for example, the damping hinge 3 can also be applied to a refrigerator.
In the description of the present specification, a particular feature, structure, material, or characteristic may be combined in any suitable manner in one or more embodiments or examples.
The present invention is not limited to the above embodiments, and any changes or substitutions that can be easily understood by those skilled in the art within the technical scope of the present invention are intended to be included in the scope of the present invention.
