[0002] When the refrigerator door in the prior art is opened, the opening speed of the door is often determined by the opening force and speed of the user. This leads to the situation that when the opening force and speed of the user are too large, on the one hand, the opening speed of the refrigerator door is too fast, which not only poses a safety hazard but also risks damaging the door and the cabinet body, affecting the service life; on the other hand, when the opening force and speed of the user are too large, it will also cause the opening angle of the door to be too large, resulting in the risk of deformation or even breakage of the door and the cabinet body, affecting the service life of the refrigerator.

[0003] Therefore, to solve the defects and deficiencies in the above prior art, the utility model provides a damping device. Summary of the Invention

[0004] To solve the defects and deficiencies in the prior art, the utility model provides a damping device.

[0005] The specific solution provided by the utility model is as follows:

[0006] A damping device includes a rotating member connected to the door and a fixed member connected to the cabinet body. The rotating member is rotatably connected to the fixed member through a first rotating shaft and a second rotating shaft. It is characterized in that: a sliding member is arranged inside the fixed member. The top of the sliding member abuts against the second rotating shaft and can slide up and down relative to the fixed member. The bottom of the sliding member is connected to the bottom of the fixed member through an elastic member.

[0007] As a further preferred embodiment of the utility model, the first rotating shaft and the second rotating shaft are fixed to the bottom of the rotating member, and the first rotating shaft is located inside the second rotating shaft.

[0008] As a further preferred embodiment of the utility model, the movement track of the first rotating shaft is circular arc-shaped, and the movement track of the second rotating shaft is L-shaped.

[0009] As a further preferred embodiment of the utility model, the fixed member includes a housing. Inside the housing, a kidney-shaped hole matching the movement track of the first rotating shaft and an L-shaped hole matching the movement track of the second rotating shaft are respectively provided.

[0010] As a further preferred embodiment of the utility model, a plurality of limiting holes with limiting members accommodated therein are further provided inside the housing. The limiting holes are respectively provided on both sides of the kidney-shaped hole and between the L-shaped holes, and on the outer side of the L-shaped hole.

[0011] As a further preferred embodiment of the present utility model, the sliding member is disposed inside the L-shaped hole and its top abuts against the second rotating shaft, and the sliding member can slide up and down inside the L-shaped hole.

[0012] As a further preferred embodiment of the present utility model, the sliding member is arranged in an L-shape matching the L-shaped hole, and a downward slope is provided on one side of the top of the sliding member close to the long side of the L-shape.

[0013] As a further preferred embodiment of the present utility model, a plurality of limiting grooves are respectively formed on the outer side and the inner side of the housing, pin holes are respectively formed inside the sliding member at positions corresponding to the limiting grooves, limiting pins are fixed inside the pin holes, and axial ends of the limiting pins extend out from the limiting grooves on both sides of the housing.

[0014] As a further preferred embodiment of the present utility model, the elastic members are respectively arranged at both ends of the bottom of the sliding member and at the bending position of the bottom L-shape.

[0015] As a further preferred embodiment of the present utility model, the elastic member is selected as a spring.

[0016] Compared with the prior art, the technical effects that the present utility model can achieve include:

[0017] 1) The present utility model provides a damping device. By arranging a sliding member inside a fixing member, the top of the sliding member abuts against the second rotating shaft and can slide up and down relative to the fixing member. The bottom of the sliding member is connected to the bottom of the fixing member through an elastic member. In this way, when the cabinet door is opened, as the opening angle continuously increases, the sliding member slides downward relative to the fixing member to compress the bottom elastic member. As the elastic member is continuously compressed, the internal elastic force thereof will provide a reverse damping force, and this damping force continuously increases as the opening angle increases. Thus, the opening speed of the cabinet door is reduced through this damping force, the safety hazard of opening and closing the cabinet door is reduced, and at the same time, the risk of damage to the cabinet door and the cabinet body is reduced, ensuring the service life of the refrigerator cabinet door.

[0018] 2) The present utility model provides a damping device. By setting the movement trajectory of the first rotating shaft as an arc and the movement trajectory of the second rotating shaft as an L shape, and respectively providing a kidney-shaped hole in the interior of the housing that matches the movement trajectory of the first rotating shaft and an L-shaped hole that matches the movement trajectory of the second rotating shaft, the opening angle of the cabinet door relative to the cabinet body is limited within the stroke ranges of the first rotating shaft and the kidney-shaped hole, and the second rotating shaft and the L-shaped hole, thereby reducing the risk of deformation or even breakage of the cabinet door and the cabinet body caused by an overly large opening rotation angle of the cabinet door, and ensuring the service life of the refrigerator cabinet door.

[0019] 3) The present utility model provides a damping device. A plurality of limiting holes with limiting members accommodated therein are provided in the interior of the housing, so as to achieve the limiting effect at different positions during the rotation of the cabinet door relative to the cabinet body through the limiting members at different positions, and further ensure the stability of the entire rotation process of the cabinet door.

[0020] 4) The present utility model provides a damping device. By respectively providing elastic members at both ends of the bottom of the sliding member and at the bent position of the bottom L shape, the cabinet door can be ensured to receive a balanced damping force at different positions during the rotation relative to the cabinet body, and further ensure the stability and balance of the damping force received during the entire rotation process of the cabinet door.

[0029] [First Embodiment]

[0030] As Figures 1-5 shown, a damping device provided by the first embodiment of the present utility model is shown. As Figure 1 shown, it includes a rotating member 1 connected to the cabinet door and a fixing member 2 connected to the cabinet body. The rotating member 1 is rotatably connected to the fixing member 2 through a first rotating shaft 11 and a second rotating shaft 12, so as to realize the rotational opening and closing of the cabinet door relative to the cabinet body.

[0031] As Figure 1 shown, in this embodiment, the first rotating shaft and the second rotating shaft are fixed to the bottom of the rotating member 1, and the first rotating shaft is located inside the second rotating shaft. The movement track of the first rotating shaft is arc-shaped, and the movement track of the second rotating shaft is L-shaped, so as to limit the opening angle of the cabinet door relative to the cabinet body, reduce the risk of deformation or even breakage of the cabinet door and the cabinet body caused by too large an opening angle of the cabinet door, and ensure the service life of the refrigerator cabinet door.

[0032] Correspondingly, as Figures 4-5As shown, the fixing member 2 includes a housing 21. Inside the housing, an oblong hole 22 that mates with the movement locus of the first rotating shaft 11 and an L-shaped hole 23 that mates with the movement locus of the second rotating shaft 12 are respectively formed. The first rotating shaft 11 is located inside the oblong hole 22, and the second rotating shaft 12 is located inside the L-shaped hole 23, thereby limiting the opening angle of the cabinet door relative to the cabinet body within the stroke ranges of the first rotating shaft and the oblong hole, and the second rotating shaft and the L-shaped hole, reducing the risk of deformation or even breakage of the cabinet door and the cabinet body caused by an overly large opening rotation angle of the cabinet door, and ensuring the service life of the refrigerator cabinet door.

[0033] Preferably, a number of limiting holes 24 with limiting members accommodated therein are further formed inside the housing. The limiting holes 24 are respectively formed on both sides of the oblong hole 22 between the L-shaped hole 23 and on the outer side of the L-shaped hole 23. Different-position limiting members are used to achieve the limiting effect at different positions during the rotation of the cabinet door relative to the cabinet body, further ensuring the stability of the whole process of the cabinet door rotation.

[0034] A sliding member 3 is arranged inside the fixing member 2. The top of the sliding member 3 abuts against the second rotating shaft and can slide up and down relative to the fixing member 2. The bottom of the sliding member 3 is connected to the bottom of the fixing member 2 through an elastic member 4. By arranging a sliding member inside the fixing member, with the top of the sliding member abutting against the second rotating shaft and capable of sliding up and down relative to the fixing member, and the bottom of the sliding member being connected to the bottom of the fixing member through an elastic member, when the cabinet door is opened, as the opening angle continuously increases, the sliding member slides downward relative to the fixing member to compress the bottom elastic member. As the elastic member is continuously compressed, the internal elastic force therein will provide a reverse damping force, and this damping force increases continuously as the opening angle increases. Thus, the opening speed of the cabinet door is reduced through this damping force, reducing the safety hazard during the opening and closing of the cabinet door and at the same time reducing the risk of damage to the cabinet door and the cabinet body, and ensuring the service life of the refrigerator cabinet door.

[0035] As Figures 2-4 shown, the sliding member 3 is arranged inside the L-shaped hole 23 and its top abuts against the second rotating shaft. The sliding member 3 can slide up and down inside the L-shaped hole 23. The sliding member 3 is arranged in an L-shape that mates with the L-shaped hole 23, and a downward slope 31 is provided on one side of the top of the sliding member 3 close to the long side of the L-shape. This is to ensure that the refrigerator cabinet door can be smoothly opened at the initial stage of opening. Therefore, when the first rotating shaft 11 is at the position of the slope 31, it will not exert a downward compression effect on the sliding member 3.

[0036] To achieve the sliding process, a number of limiting grooves 25 are respectively provided on the outer and inner sides of the housing 21. At positions corresponding to the limiting grooves 25 inside the sliding member 3, pin holes 32 are respectively provided. A limiting pin 5 is fixed inside the pin holes 32, and both axial ends of the limiting pin 5 extend out from the limiting grooves 25 on both sides of the housing 21. Through the arrangement of the limiting pin 5 and the limiting grooves 25, the limiting effect on the sliding process of the sliding member 3 is effectively achieved to avoid sliding deviation during its sliding.

[0037] As Figures 2-4 shown, in this embodiment, the elastic member 4 is selected as a spring. The elastic members 4 are respectively arranged at both bottom ends and the bent position of the bottom L shape of the sliding member 3. One end of the elastic member 4 is fixedly connected to the elastic member fixing part extending from the bottom of the sliding member 3, and the other end of the elastic member 4 is fixedly connected to the bottom of the fixing member 2, so as to ensure that balanced damping forces can be received at different positions during the rotation of the cabinet door relative to the cabinet body, and further ensure the stability and balance of the damping forces received during the whole process of the rotation of the cabinet door.

[0038] As a further preference, in order to further ensure the stability and effectiveness of the damping effect, other types of dampers (such as cylinder dampers) can also be used between the cabinet door and the cabinet body, etc., to jointly provide damping forces with this damping device.

[0039] During specific operation:

[0040] When the cabinet door is opened, the rotating member 1 connected to the cabinet door rotates clockwise (as Figure 5 shown) relative to the fixing member 2 connected to the cabinet body. At this time, the first rotating shaft 11 moves from right to left inside the kidney-shaped hole 22 (as Figure 5 shown), and the second rotating shaft 12 moves from bottom to top in the L-shaped hole 23 (as Figure 5 shown). At the initial stage of opening the cabinet door, the first rotating shaft 11 is located at the slope 31 position and will not produce a downward compression effect on the sliding member 3, so it does not compress the elastic member 4 and thus does not generate a damping force. This free stroke facilitates the normal opening of the cabinet door. As the opening angle of the cabinet door increases, the sliding member 3 descends inside the fixing member 2 and compresses the elastic member 4. As the elastic member 4 is continuously compressed, the internal elastic acting force thereof will provide a reverse damping force, and this damping force increases continuously as the opening angle increases, so as to reduce the opening speed of the cabinet door through this damping force.

[0041] When the cabinet door is closed, the rotating member 1 connected to the cabinet door rotates counterclockwise (as Figure 5 shown) relative to the fixing member 2 connected to the cabinet body. At this time, the first rotating shaft 11 moves from left to right inside the kidney-shaped hole 22 (as Figure 5 shown), and the second rotating shaft 12 moves from top to bottom in the L-shaped hole 23 (as Figure 5As shown, the damping force generated by the compression of the elastic member 4 further helps the cabinet door to close until the damping force disappears when the first rotating shaft 11 reaches the ramp 31 position.
