AI Technical Summary
Traditional refrigerators often produce noise during the opening and closing of doors, especially when people are in a quiet night, which may cause interference to users.
A new low-noise refrigerator hinge was designed. By introducing a combination of dampers, springs and bent plates into the hinge structure, the dampers consume energy and spring buffer shocks, reducing vibration and impact, thereby reducing noise when the refrigerator door is closed.
It effectively reduces the noise when the refrigerator is closed, providing a smoother movement and a quieter user experience.

[0020] Embodiment:
[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution: a novel low-noise freezer hinge, which includes a first mounting plate 1 and two second mounting plates 9. A first hinge plate 2 is arranged in the middle of the front wall of the first mounting plate 1. A second hinge plate 8 is arranged between the two second mounting plates 9. A bent plate 5 and a stabilizing plate 6 are hinged between the first hinge plate 2 and the second hinge plate 8. A groove is opened at the middle position of the first mounting plate 1, and a damper 12 is fixedly connected inside the groove. A spring 11 is arranged between the damper 12 and the bent plate 5. First pins 3 are installed at the joints of the bent plate 5 with the first hinge plate 2 and the second hinge plate 8. Second pins 4 are installed at the joints of the stabilizing plate 6 with the first hinge plate 2 and the second hinge plate 8. A through groove is opened at the joint of the stabilizing plate 6 and the second pin 4, and the second pin 4 is rotatably connected to the inner wall surface of the through groove.
[0022] Among them, sleeves 13 are fixedly connected to both ends of the bent plate 5. The first pin 3 passes through the inside of the sleeve 13, and the first pin 3 is slidably connected to the inner wall surface of the sleeve 13. Hooks are fixedly connected to both ends of the spring 11. A fixed block 14 is connected to the front wall surface of the damper 12. A through hole 15 is opened inside the fixed block 14. A ring 10 is fixedly connected to the outer wall surface of the bent plate 5. The ring 10, the through hole 15 and the hooks at both ends of the spring 11 are adapted to each other. The damper 12 and the bent plate 5 are connected by the spring 11. Four bolts 7 are installed inside the first mounting plate 1, and two bolts 7 are installed inside the second mounting plate 9. Corrosion-resistant layers are sprayed on the outer wall surfaces of the first mounting plate 1 and the two second mounting plates 9. Openings are arranged on the surfaces of the first hinge plate 2 and the second hinge plate 8 close to each other.
[0023] Working principle: First, install the first mounting plate 1 on the freezer main body, and install the two second mounting plates 9 at appropriate positions on the cabinet door. When the cabinet door is opened, the spring 11 is stretched. The main function of the spring 11 is to provide elasticity, store and release energy. When subjected to an external force, the spring 11 deforms and absorbs energy; when the external force disappears, that is, when the freezer cabinet door is closed, the spring 11 will return to its original shape and release energy. The spring 11 can buffer impacts, reduce vibrations, and provide smooth movement. The main function of the damper 12 is to consume energy and reduce the vibration amplitude. The damper 12 can absorb and dissipate energy through friction, liquid resistance or other mechanisms. When the spring 11 and the damper 12 are connected in parallel, the damper 12 can prevent the rapid rebound movement of the spring 11 and consume the stored energy, thereby reducing vibrations and impacts and greatly reducing the noise generated when the cabinet door is closed.
[0024] The above has shown and described the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention; therefore, from any point of view, the embodiments should be regarded as exemplary and non-limiting. The scope of the present invention is defined by the appended claims rather than the above description. Therefore, all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present invention, and any reference signs in the claims should not be regarded as limiting the claims involved.
