DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] See also Figures 1 to 3 , the utility model provides a technical solution:

[0019] A sound-absorbing bottom plate for a refrigerator comprises a first steel plate 1, a mounting groove 2 being provided in the middle of the first steel plate 1, and a fixing plate 3 and a protective plate 4 being installed around the outer sides of the mounting groove 2, respectively. The fixing plate 3 is fixedly installed on the top of the first steel plate 1, and the protective plate 4 is slidably installed on the top of the first steel plate 1, and a telescopic rod 5 and a first spring 6 are fixedly installed between the protective plate 4 and the fixed plate 3, and the first spring 6 is sleeved on the outer side of the telescopic rod 5. A buffer plate 7 is installed inside the mounting groove 2, and a second steel plate 8 is installed below the buffer plate 7. A plurality of groups of hydraulic dampers 9 and a mitigation component are installed between the second steel plate 8 and the bottom wall of the mounting groove 2, and the hydraulic damper 9 is installed between the mitigation components.

[0020] By setting up a protective plate 4, the situation of direct collision with the refrigerator is avoided, and the side of the bottom end of the refrigerator is protected. When a collision occurs, it will hit the protective plate 4, and the protective plate 4 squeezes the telescopic rod 5 and the first spring 6 to offset the force generated by the collision. By setting up a second steel plate 8 to support the refrigerator, the buffer plate 7 achieves the purpose of isolating noise. When the refrigerator is placed on the second steel plate 8, the mitigation component and the hydraulic damper 9 are set to play a buffering role, further protecting the refrigerator. At the same time, when the refrigerator is working, it can also slow down the amplitude of the vibration generated by the refrigerator, thereby achieving the purpose of reducing sound and noise. It should be noted that the protective plate 4 and the buffer plate 7 here are both made of foam board material.

[0021] A sound-absorbing cavity is provided in the first steel plate 1 and below the mounting groove 2 , and sound-absorbing cotton 18 is installed inside the sound-absorbing cavity.

[0022] A baffle 17 is installed on the inner wall of the sound absorbing cavity, and the baffle 17 is wavy in shape.

[0023] When the refrigerator is working and making noise, part of the noise will pass through the first steel plate 1 and the buffer plate 7 into the silencer cavity 15 inside the first steel plate 1. At this time, the noise is isolated and reduced. The gaps and small holes in the sound-absorbing cotton 18 weaken the multiple reflections of the sound. At the same time, the wave baffle 17 also reflects the sound multiple times, thereby reducing the noise.

[0024] The mitigation component includes a T-rod 10 installed at the bottom of the buffer plate 7, a sleeve 11 sleeved on the outside of the T-rod 10, and a buffer pad 12 arranged inside the sleeve 11. The sleeve 11 is installed on the inner bottom wall of the mounting groove 2, and the buffer pad 12 is installed between the T-rod 10 and the sleeve 11. When the refrigerator is placed on the second steel plate 8, the T-rod 10 will be squeezed to slide inside the sleeve 11 and squeeze the buffer pad 12 to achieve the purpose of buffering.

[0025] A plurality of sets of U-shaped limit rods 13 are symmetrically fixedly installed at the bottom of the mounting groove 2. A slider 15 and a second spring 14 are sleeved on the outer side of the U-shaped limit rod 13. One end of the second spring 14 is connected to the U-shaped limit rod 13, and the other end is connected to the slider 15. A movable rod 16 is movably connected between the slider 15 and the T-shaped rod 10. When the T-shaped rod 10 slides, it will drive one end of the movable rod 16 to move downward, so that the other end drives the slider 15 to squeeze the second spring 14, thereby improving the buffering effect.

[0026] Finally, a few points should be explained: First, in the description of this application, it should be noted that, unless otherwise specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense, and may refer to mechanical or electrical connections, internal communication between two components, or direct connection. "Up," "down," "left," and "right" are only used to indicate relative positional relationships. When the absolute positions of the objects being described change, the relative positional relationships may also change.

[0027] Secondly: The drawings of the embodiments disclosed in this utility model only involve structures related to the embodiments disclosed in this utility model. Other structures can refer to common designs. In the absence of conflicts, the same embodiment and different embodiments of the utility model can be combined with each other.

[0028] Finally: The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.

[0029] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
