The freezer compartment has an opening on the cabinet, and a freezer door 41 is provided at the opening. The freezer door includes an upper cover plate and a lower cover plate 411. The lower cover plate is provided with a hinge cavity 412. A hinge boss 102 is provided on the top cover plate 101 of the cabinet corresponding to the hinge cavity. Hinges 410 are respectively installed on the mounting plates of the hinge boss and the hinge cavity, so that one side of the freezer door is rotatably mounted on the cabinet. The freezer door has a apex angle 415 at the hinge end. When the apex angle 415 touches the hinge boss, the freezer door is restricted. The restricted opening degree of the freezer door is within the range of greater than 90 degrees and less than 135 degrees.

[0022] The top cover plate 101 is provided with a groove 103, which is used to avoid the travel trajectory of the top corner when the freezer door is opened, and the hinge boss is provided on the groove.

[0023] The hinge boss is provided with an outer base 1021, which has a rounded corner structure. This rounded corner structure is also to avoid the travel trajectory of the top corner of the freezer door when the freezer door is opened.

[0024] One side of the freezer door 41 is rotatably mounted on the cabinet 1. The cabinet 1 is provided with a lock body for locking the closed freezer door 41 onto the cabinet 1. The lock body is a mechanical lock. The cabinet 1 is provided with a first locking ring 42. The freezer door 41 is provided with a second locking ring 43 corresponding to the position of the first locking ring 42. The locking hook of the mechanical lock passes through the first locking ring 42 and the second locking ring 43 and locks onto the mechanical lock, thereby locking the freezer door 41.

[0025] The refrigerator body 1 is equipped with a pull handle 2, and casters 5 are located at the bottom of the body 1. The pull handle 2 includes a fixed outer tube 21, a telescopic inner tube, and a handle body 23. The fixed outer tube 21 is vertically mounted on the body 1, and the telescopic inner tube extends vertically within the fixed outer tube 21. The handle body 23 is located at the upper end of the telescopic inner tube. With the telescopic inner tube extending out of the fixed outer tube 21, the refrigerator can be easily moved by the user. When the telescopic inner tube retracts into the fixed outer tube 21, the refrigerator can be easily stored in a vehicle.

[0026] The inner cavity of the box 1 is divided into an insulation cavity and an electrical cavity 12 on the left and right. The freezer compartment is located in the insulation cavity area. The box 1 is provided with at least two battery compartments, and batteries 7 are provided in the at least two battery compartments. The battery compartments are provided with openings on the box 1, and the openings are provided with openable battery compartment doors 71.

[0027] The freezer compartment door 41 and the battery compartment door 71 are rotatably located on the top of the housing 1. This allows the user to easily open the freezer compartment 4 and the battery compartment to remove the medicine and the battery 7.

[0028] The freezer compartment 4 is cubic in shape, with an opening on the top surface of the freezer compartment 4. The evaporator is attached to the bottom surface and four sides of the freezer compartment 4.

[0029] The housing 1 is equipped with a touch screen display 6, a power switch, a data transmission interface, and a charging port.

[0030] The housing 1 is equipped with a GPS antenna and a WiFi antenna. This vehicle-mounted medical refrigerator transmits location signals to hospitals and other locations via the GPS antenna, allowing medical personnel to monitor the real-time location of the refrigerator and medications. The vehicle-mounted medical refrigerator also transmits and receives signals via the WiFi antenna, enabling communication with the outside world.

[0031] A Hall effect switch is installed next to the opening of the freezer compartment 4, and a magnet is installed on the freezer compartment door 41 at the position corresponding to the Hall effect switch. When the freezer compartment door 41 is not closed, the Hall effect switch activates the alarm circuit and sends a signal to the main control board. The touch screen 6 displays an alarm symbol, thus reminding the user to close the freezer compartment door 41 to prevent the loss of cold air from the freezer compartment 4. When the freezer compartment door 41 is closed, the Hall effect switch deactivates the alarm circuit and sends a signal to the main control board. The touch screen 6 stops displaying the alarm symbol.

[0032] The working principle of this utility model:

[0033] When it is necessary to close the freezer door 41 to store medicine, the operator rotates the freezer door 41 so that it fits against the opening 42 of the cabinet 1. Then, the locking hook of the mechanical lock passes through the first locking ring 42 on the cabinet 1 and the second locking ring 43 on the freezer door 41, and locks the mechanical lock, thus reliably securing the freezer door 41. This locking structure effectively prevents the freezer door 41 from loosening or accidentally opening due to vehicle bumps, ensuring the sealing performance of the freezer compartment 4, reducing cold loss, and maintaining a stable low-temperature environment.

[0034] The open / closed status of the freezer door 41 is monitored in real time via a Hall effect switch. When the freezer door 41 is not fully closed, the Hall effect switch senses this and activates the alarm circuit, transmitting a signal to the main control board. Upon receiving the signal, the main control board controls the touchscreen display 6 to display an alarm symbol, promptly reminding the operator to close the freezer door 41 to prevent continuous loss of cold air. When the operator fully closes the freezer door 41 and locks it with the mechanical lock, the Hall effect switch senses this and disconnects the alarm circuit, simultaneously sending a normal signal to the main control board. The touchscreen display 6 then stops displaying the alarm symbol, and the refrigerator returns to normal operation.

[0035] When this utility model is in operation, after the user presses the power switch, the battery 7 supplies power to the refrigeration system, and the refrigeration system starts working. The compressor 31 and the cooling fan 35 start, and the evaporator begins to cool, causing the temperature of the freezer compartment 4 to decrease until it reaches the set refrigeration temperature, and then the temperature of the freezer compartment 4 is maintained. The cooling fan 35 dissipates heat from the compressor 31 and the condenser 32. Cold air enters the electrical cavity 12 through the air inlet, carrying away the heat from the compressor 31 and the condenser 32, and then exits the electrical cavity 12 through the air outlet.

[0036] This invention features a compact structure, excellent cooling effect in the freezer compartment, precise temperature control, and low cooling temperature, achieving the temperatures required for frozen storage of medicines and medical supplies, such as -25 degrees Celsius or even lower. The invention incorporates a pull handle and wheels on the cabinet, allowing users to easily move the refrigerator with minimal effort. A reserve battery provides power in emergencies.

[0037] The embodiments of this utility model have been described in detail above with reference to the accompanying drawings, but this utility model is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of this utility model, and these variations still fall within the protection scope of this utility model.
