[0003] In this regard, China's patent application number is CN202320494483.X, which discloses a refrigerated compartment with a sealing mechanism. The scheme uses a motor to drive the door panel to open upward, and at the same time drives the clamping plate to lift upward, so as to achieve the effect of releasing the pressure when the door is opened.

[0004] However, in the process of implementing the technical solution in the embodiments of the present application, the inventor of the present application found that the above technology has at least the following technical problems:

[0015] In the above implementation process, the cable is wound by rotating the rotating shaft, thereby pulling up the pressure plate.

[0016] In a specific embodiment, two rotating shafts are arranged in the carriage, and two pulling cables are wound around each rotating shaft.

[0017] In a specific embodiment, each of the rotating shafts is axially connected to a motor, and the motor is mounted on the bracket.

[0018] In the above implementation process, two servo motors drive the rotating shaft to rotate, thereby winding four cables to pull up the pressure plate in a balanced manner, which is conducive to receiving the pressure plate on the top of the car and reducing the space occupied.

[0019] In a specific implementation, the draw rope encoder is installed on the top of the rear end of the carriage, and the draw rope end of the draw rope encoder is fixedly connected to the door panel.

When the door panel is opened and closed, the pull-wire encoder is driven to move, thereby obtaining a door opening signal to drive the motor to rotate.

[0021] Compared with the prior art, the beneficial effects of the present application are: the pull-wire encoder can accurately capture the action of the door panel switch, and then control the action of the winding member to pull up the pressure plate, thereby achieving the effect of unlocking and holding the door when it is opened. The pull-wire encoder can be easily installed on the door panel of the existing refrigerated compartment, with low modification cost and easy promotion. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The technical solutions in the embodiments of the present application will be described below in conjunction with the drawings in the embodiments of the present application.

[0029] See also Figure 1-Figure 4 The present application provides a refrigerated compartment with a sealing mechanism, including a compartment 10, a pressure plate 20 is elastically connected in the compartment 10, a winding member 30 is connected to the pressure plate 20, a double-opening door panel 40 is hinged at the rear of the compartment 10, and a pull-wire encoder 50 is provided on the door panel 40 and electrically connected to the winding member 30. The pull-wire encoder 50 can accurately capture the action of the door panel 40 opening and closing, and then control the winding member 30 to pull up the pressure plate 20, so as to achieve the effect of unlocking and holding the door when opening. The pull-wire encoder 50 can be conveniently installed on the existing door panel 40 of the refrigerated compartment 10, with low modification cost and easy promotion.

[0030] See also Figure 1-Figure 4 A sealing strip 60 is provided on the door panel 40. The sealing strip 60 is used to ensure the airtightness between the door panel 40 and the compartment 10 and improve the heat preservation effect.

[0031] See also Figure 1-Figure 4 The top of the carriage 10 is fixedly connected with a bracket 70, and a spring 80 is arranged between the bracket 70 and the pressure plate 20. The bracket 70 is used to install the spring 80, and then the pressure plate 20 is installed through the spring 80.

[0032] See also Figure 1-Figure 4 , four brackets 70 are provided, and each bracket 70 is provided with a spring 80. Four springs 80 can provide a more stable pressing effect.

[0033] See also Figure 1-Figure 4 The winding member 30 includes a rotating shaft 31, which is rotatably connected to the bracket 70. A cable 32 is wound on the rotating shaft 31, and the lower end of the cable 32 is fixedly connected to the pressing plate 20. The cable 32 is wound by rotating the rotating shaft 31, and then the pressing plate 20 is pulled up.

[0034] See also Figure 1-Figure 4Two rotating shafts 31 are arranged in the carriage 10, and two cables 32 are wound around each rotating shaft 31. A motor 33 is connected to each rotating shaft 31, and the motor 33 is mounted on the bracket 70. The two servo motors 33 drive the rotating shafts 31 to rotate, so that the four cables 32 are wound around to pull up the pressing plate 20 in a balanced manner, which is conducive to receiving the pressing plate 20 at the top of the carriage 10 and reducing the space occupied.

[0035] See also Figure 1-Figure 4 The pull-wire encoder 50 is installed at the top of the rear end of the carriage 10, and the pull-wire end of the pull-wire encoder 50 is fixedly connected to the door panel 40. The pull-wire encoder 50 is installed at the corner of the carriage 10, which is beneficial to reduce the space occupied in the carriage 10. When the door panel 40 is opened and closed, the pull-wire encoder 50 is driven to move, thereby obtaining a door opening signal to drive the motor 33 to rotate.

[0036] The working principle of the refrigerated compartment with a sealing mechanism is: when the door panel 40 is closed, four springs 80 push the pressure plate 20 to press the goods to prevent the goods from sliding during transportation. When the door panel 40 is opened, the pull rope encoder 50 is pulled to obtain a door opening signal and drive the motor 33 to operate. The motor 33 drives the rotating shaft 31 to rotate, winds up the pull rope 32, and then pulls up the pressure plate 20, thereby unlocking the pressure on the goods. In summary, the pull rope encoder 50 can accurately capture the action of the door panel 40 switch, and then control the winding member 30 to pull up the pressure plate 20, thereby achieving the effect of unlocking the pressure when opening the door. The pull rope encoder 50 can be conveniently installed on the door panel 40 of the existing refrigerated compartment 10, with low modification cost and easy promotion.
