Description

Technical Field

[0001] This utility model relates to the technical field of door panel buffer equipment, and specifically to a cold storage door panel buffer assembly that is easy to maintain. Background Technology

[0002] Cold storage door panels are a major structural component of cold storage doors, providing insulation, sealing, and durability. They are used to maintain the low-temperature environment inside the cold storage and prevent external heat from entering. Cold storage door panels typically employ special materials and structural designs to ensure excellent insulation and sealing performance even in extremely low-temperature environments.

[0003] Chinese patent publication number CN217058127U discloses a cold storage panel with an anti-locking structure, including a cold storage door frame. The front end of the cold storage door frame is connected to a cold storage door panel via a connecting rod. The upper and lower ends of the connecting rod are installed on the outer wall of the front end of the cold storage door frame via an installation mechanism. The middle part of the right side of the front end of the cold storage door panel is limited to the cold storage door frame by a locking mechanism. The locking mechanism includes a through rod, a first rotating gear, a turntable, a handle, a second rotating gear, a fixed rod, a limiting fixing block, a limiting groove, and a limiting protrusion. The limiting fixing block is fixedly connected to the middle part of the right side of the front end of the cold storage door frame, and a limiting groove is formed at the bottom left end of the front end of the limiting fixing block.

[0004] When existing cold storage door panels are closed, the door panel collides with the door frame. Most existing cold storage door panels use rubber for cushioning. However, due to the low temperature inside the cold storage, the molecular movement of rubber materials slows down in the low-temperature environment, resulting in a decrease in their flexibility and even making them hard and brittle. This leads to a poorer cushioning effect of the rubber. Therefore, it is necessary to develop a cold storage door panel with better cushioning effect. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Example:

[0025] like Figure 1-4 As shown in this embodiment, the easily maintainable cold storage door panel buffer assembly includes a door frame 1, with a door panel 2 hinged to the inner side of the door frame 1; a limiting plate 3, which is disposed on the inner side of the door frame 1 and is used to restrict the movement of the door panel 2; and a magnetic buffer mechanism, which includes two permanent magnets 9 and two electromagnets 10. The electromagnets 10 are disposed on the outer side of the limiting plate 3, and the permanent magnets 9 are disposed on the inner side of the door panel 2 and correspond to the electromagnets 10. When the door panel 2 is closed, the electromagnets 10 are activated, causing the electromagnets 10 and the permanent magnets 9 to repel each other, and then the door panel 2 moves towards the limiting plate 3. The door panel 2 moves in the direction of the limit plate 3. When the door panel 2 approaches the limit plate 3, the moving speed of the door panel 2 decreases under the repulsive action of the permanent magnet 9 and the electromagnet 10, thereby achieving buffering of the door panel 2. After the door panel 2 enters the door frame 1, the magnetic pole of the electromagnet 10 is reversed, so that the electromagnet 10 and the permanent magnet 9 attract each other, thus completing the fixation of the door panel 2. By setting the electromagnet 10 and the permanent magnet 9 to buffer the door panel 2, the impact force between the door panel 2 and the door frame 1 is greatly reduced, the service life of the door panel 2 is extended, and by reversing the magnetic pole of the electromagnet 10, the door panel 2 can also be tightly fixed in the door frame 1, improving the sealing performance of the device.

[0026] A proximity sensor 8 is provided on the inner side of the door frame 1, and an acceleration sensor 5 is provided on the side of the door panel 2. The proximity sensor 8 is used to detect whether the door panel 2 has entered the door frame 1, and the acceleration sensor 5 is used to detect the moving speed of the door panel 2. When the moving speed of the door panel 2 is fast, the magnetic force of the electromagnet 10 is strengthened to increase the repulsive force between the electromagnet 10 and the permanent magnet 9. When the moving speed of the door panel 2 is slow, the magnetic force of the electromagnet 10 is reduced to prevent the door panel 2 from failing to enter the door frame 1 due to the repulsive force. By setting the acceleration sensor 5 and the proximity sensor 8, the device can flexibly adjust the magnetic force of the electromagnet 10 according to the moving speed of the door panel 2, thus ensuring the buffering performance of the device.

[0027] Heating elements 7 are provided above and below the proximity sensor 8. The heating elements 7 are attached to the inner side of the door frame 1 and are used to heat the door panel 2 to prevent the door panel 2 from freezing.

[0028] The door panel 2 is provided with a handle 6 on its side.

[0029] The limiting plate 3 has a gasket 4 on the side near the door panel 2, and the gasket 4 is made of EPDM rubber.

[0030] Working principle

[0031] When the door panel 2 is closed, the electromagnet 10 is activated, causing the electromagnet 10 and the permanent magnet 9 to repel each other. Then, the door panel 2 moves towards the limiting plate 3. The acceleration sensor 5 adjusts the magnetic force of the electromagnet 10 according to the detected moving speed of the door panel 2. When the door panel 2 approaches the limiting plate 3, the moving speed of the door panel 2 decreases under the repulsive action of the permanent magnet 9 and the electromagnet 10, thereby achieving buffering of the door panel 2. After the proximity sensor 8 detects that the door panel 2 has entered the door frame 1, it reverses the magnetic poles of the electromagnet 10, causing the electromagnet 10 and the permanent magnet 9 to attract each other, thus completing the fixation of the door panel 2.
