Technical Field

[0001] The present application relates to the technical field of household appliances, and in particular to a refrigerator door damper and a refrigerator thereof. Background Art

[0002] Refrigerators are essential appliances in modern households, and their convenience and stability are of great concern. Frequent opening and closing of refrigerator doors can cause impact and vibration to the door structure. Long-term impact and vibration can damage the door components, even affecting the refrigerator's sealing performance and overall service life. Furthermore, opening and closing the door creates a lot of noise, impacting the user experience.

[0003] Currently, existing technologies for damping refrigerator door shock still present challenges. Some refrigerators use simple rubber pads to mitigate impact, but these materials have limited damping effectiveness and are prone to aging and deformation over time, gradually losing their ability to absorb shock. Other refrigerators use complex hydraulic or pneumatic damping devices. While these devices offer good damping, they are expensive and difficult to install and maintain, increasing production and after-sales costs. Utility Model Content

[0016] In one of the embodiments, a baffle is arranged on the pressure rod, and an end of the spring away from the base is limited by the baffle.

[0017] In one of the embodiments, the baffle is detachably connected with the pressure rod, and the mounting position of the baffle on the pressure rod can be adjusted along the axis direction of the pressure rod.

[0018] It can be understood that, by detachably connecting the baffle with the pressure rod and adjusting the position, the pre-tightening force of the spring can be adjusted according to different damping requirements, thereby improving the adaptability of the damper.

[0019] In one of the embodiments, the baffle is sleeved on the pressure rod and is threadedly connected with the pressure rod.

[0021] In one of the embodiments, the seat body and the connecting body are integrally formed; and / or, a second flexible layer is arranged on the surface of the connecting body.

[0022] It can be understood that the second flexible layer can cooperate with the spring to absorb part of the impact force, thereby improving the damping effect.

[0023] The application also provides the following technical solutions:

[0024] A refrigerator comprises a cabinet, a refrigerator door and a refrigerator door shock absorber as claimed in any one of the preceding claims, which is mounted on the cabinet or the refrigerator door.

[0025] Compared with the prior art, the refrigerator door shock absorber and the refrigerator thereof can reduce the shock and noise generated when the refrigerator door is closed by setting a pressing rod and a spring, contacting the refrigerator door with the shock absorbing end and then absorbing the impact force when the door is closed by spring compression.

[0040] Please refer to Figure 1The refrigerator door shock absorber 100 is installed in a cabinet 220 of a refrigerator 200, and is used to absorb the shock generated when a refrigerator door 210 is closed.

[0041] Specifically, referring to Figures 2-3 , the refrigerator door shock absorber 100 comprises a base 10, a pressing rod 20, and a spring 30. The base 10 is used to be installed on the cabinet 220 of the refrigerator 200, and a channel 11 is formed on the base 10. One end of the pressing rod 20 extends into the channel 11 and can move in the channel 11 along the axial direction of the channel 11, and the other end is configured as a shock absorbing end 21. The spring 30 is sleeved on the pressing rod 20, and one end of the spring 30 is limited on the base 10, and the other end is limited on the pressing rod 20. In response to the pressing of the shock absorbing end 21 by the refrigerator door 210, the pressing rod 20 performs a telescopic movement in the channel 11 and can compress the spring 30. In this way, by arranging the pressing rod 20 connected with the spring 30, cooperating with the base 10 with the channel 11, when the refrigerator door 210 is closed, the shock absorbing end 21 is pressed, the telescopic movement of the pressing rod 20 in the channel 11 causes the spring 30 to be compressed and effectively absorbs the impact force, thereby reducing the shock and noise generated when the refrigerator door 210 is closed. The overall structure is not only simple, but also low in cost. Compared with the traditional rubber pad, the spring 30 has better strength, rigidity and fatigue resistance, and has a longer service life.

[0042] Please refer to Figures 3-5 , the base 10 comprises a seat body 12 and a connecting body 13, and a cavity 14 is formed between the connecting body 13 and the seat body 12. The channel 11 is formed on the connecting body 13 and communicates with the cavity 14. The end of the pressing rod 20 extending into the channel 11 can extend into the channel 11 in response to the pressing force of the refrigerator door 210, and the end of the spring 30 away from the shock absorbing end 21 abuts against the connecting body 13.

[0043] Preferably, the cavity 14 can be in a shape of a hemisphere, an ellipsoid, a rectangle, etc. The end of the pressing rod 20 close to the cavity 14 enters the cavity 14 through the channel 11 under the action of the force when the refrigerator door 200 is closed.

[0044] In this embodiment, the cavity 14 is in a shape of a hemisphere.

[0045] As shown in Figure 3 and Figure 5 , the seat body 12 and the connecting body 13 are integrally formed, which is more convenient for processing. Here, the seat body 12 and the connecting body 13 can be integrally formed by injection molding or extrusion molding. For example, the base 10 is made of engineering plastic and is integrally formed by injection molding. For another example, the base 10 is made of metal such as stainless steel or aluminum alloy.

[0046] Further, the surface of the connecting body 13 is provided with a second flexible layer (not shown in the figure), and the end of the spring 30 away from the damping end 21 abuts against the second flexible layer. In this way, when the spring 30 is compressed, the second flexible layer will be deformed by the extrusion of the spring 30, so that the secondary deformation energy absorption can be achieved, and the vibration and noise generated when the refrigerator door 210 is closed can be further reduced.

[0047] Please refer to Figure 3 and Figure 5 It is shown that the pressing rod 20 can be circular, square, etc.

[0048] In an embodiment, the end surface of the damping end 21 is configured as a plane 211. In this way, the contact area with the refrigerator door 210 is increased, so that the contact between the damping end 21 and the refrigerator door 210 is more stable, and the damping effect is more uniform.

[0049] Further, the plane 211 is provided with a first flexible layer (not shown in the figure). Here, the first flexible layer can reduce the impact between the refrigerator door 210 and the damping end 21 and absorb energy, so as to reduce the noise when the refrigerator door 210 is closed and reduce the wear of the refrigerator door 210.

[0050] As preferred, the first flexible layer is configured as any one or more of a rubber layer, a sponge layer or a cloth layer. In this embodiment, the first flexible layer is provided as a cloth layer. Of course, it is not limited thereto, and the first flexible layer can also be selected and provided according to practical needs.

[0051] Please continue to refer to Figures 3-5 , the pressing rod 20 is provided with a baffle 22, and the end of the spring 30 away from the base 10 is limited in the baffle 22.

[0052] Here, the baffle 22 and the pressing rod 20 can be connected by using a non-detachable structure such as welding, bonding, etc., or can be connected by using a detachable structure such as threaded connection, clamping, etc.

[0053] Preferably, the baffle 22 and the pressing rod 20 are detachably connected, and the mounting position of the baffle 22 on the pressing rod 20 can be adjusted along the axis direction of the pressing rod 20. It can be understood that the distance between the baffle 22 and the connecting body 13 determines the initial compression value of the spring 30. The mounting position of the baffle 22 on the pressing rod 20 can be adjusted, so that the distance between the baffle 22 and the connecting body 13 can be changed, thereby changing the pre-compression value of the spring 30. That is, by such arrangement, the pre-tightening force of the spring 30 can be adjusted according to different damping requirements, and the adaptability of the refrigerator door damper 100 is improved.

[0054] In this embodiment, the baffle 22 is sleeved on the pressing rod 20 and is threadedly connected with the pressing rod 20.

[0055] As Figures 1-2As shown, the application also provides a refrigerator 200, which comprises a cabinet 220, a refrigerator door 210 and the refrigerator door damper 100 of any of the above embodiments, the refrigerator door damper 100 being mounted on the cabinet 220 or the refrigerator door 210.

[0056] Here, the refrigerator door damper 100 is mounted on the top of the cabinet 220, the base 10, the spring 30 and the baffle 22 of the refrigerator door damper 100 being arranged inside the cabinet 220, and the pressing rod 20 being arranged outside the cabinet 220 and towards the refrigerator door 210.

[0057] The technical features of the above embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, however, as long as the combinations of the technical features do not contradict each other, they shall be deemed to be within the scope of the present application.

[0058] The above embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it shall not be understood as a limitation on the patent scope of the present application. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of the present application, and these shall be deemed to be within the protection scope of the present application. Therefore, the patent protection scope of the present application shall be subject to the appended claims.
