Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, and in particular to a vehicle refrigerator with an external Type-C interface on the motherboard. Background Technology

[0002] Currently, vehicle-mounted refrigerators are increasingly widely used due to their convenience, especially in the medical field. Because some medications require low-temperature storage, vehicle-mounted refrigerators are becoming indispensable when carrying or transferring such medications. However, some medications have strict temperature requirements; excessively high or low temperatures can affect their efficacy. Existing vehicle-mounted medical refrigerator door structures have the following problems: the main control board is built-in with no external interface, upgrades require disassembly, which can easily damage the equipment and is costly. Therefore, we propose a vehicle-mounted medical refrigerator door structure to solve these problems. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a car refrigerator with an external Type-C interface on the motherboard, which can facilitate motherboard upgrades at any time, thus overcoming the shortcomings of the prior art.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0005] A car refrigerator with an external Type-C interface on the motherboard includes a cabinet and a tow handle. The cabinet contains a main control board, a refrigeration system, a freezer compartment, and a battery compartment. The refrigeration system includes a compressor, a condenser, a throttling device, a cooling fan, and an evaporator. The battery compartment contains a battery. The refrigerator is characterized by further including a Type-C interface. The cabinet also has a touch screen, a power switch, a charging port, and the Type-C interface is a data transmission interface connected to the main control board for upgrading the main control board.

[0006] The enclosure is equipped with a GPS antenna and a WiFi antenna.

[0007] The enclosure includes a main body, an electrical cavity cover, and a top cover. The inner liner of the freezer compartment is located inside the main body. The top cover seals the top openings of the main body and the electrical cavity cover. The top cover has a freezer compartment opening, a first mounting base for mounting the touch screen, and a battery compartment. The first mounting base has a rectangular frame with corner plates at the four corners. The bottom of the rectangular frame is connected to the electrical cavity. Screw posts are provided around the perimeter of the rectangular frame. The top of the screw posts is connected to the lower surface of the top cover. The main control board is mounted on the lower end of the screw posts.

[0008] The main housing consists of side panels, an electrical cavity cover, and a top cover, forming an electrical cavity. The compressor, condenser, and cooling fan are installed inside the electrical cavity. The compressor's frequency converter, battery management board, and auxiliary control board are installed on the side panels of the main housing.

[0009] The above technical solution has the following beneficial effects:

[0010] This invention provides an external Type-C interface for the motherboard, making motherboard upgrades convenient and efficient. The Type-C data transmission interface is directly connected to the main control board, allowing motherboard program upgrades to be performed without disassembling the enclosure. This avoids the risk of damage to components during disassembly, reduces maintenance time, and significantly saves maintenance costs. Attached Figure Description

[0017] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0018] See Figures 1-6 As shown, this utility model discloses a car refrigerator with an external Type-C interface on the motherboard. It includes a cabinet, inside which is a main control board, a refrigeration system, a freezer compartment 4, and a battery compartment 132. The refrigeration system includes a compressor (not shown), a condenser 32, a throttling device, a cooling fan, and an evaporator. The battery compartment contains a battery 9. The cabinet 1 is equipped with a touch screen display 64, a power switch 18, a data transmission interface 17, and a charging port 19. The data transmission interface 17 facilitates easy motherboard upgrades. The charging port 19 connects to a power outlet to charge the battery 7.

[0019] Data transmission interface 17 is a Type-C interface. The Type-C interface has a fast transmission rate, is easy to plug in either way, and has high compatibility, enabling efficient data interaction between the main control board and external devices.

[0020] The container 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 staff 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.

[0021] The enclosure includes a main body 11, an electrical cavity cover 12, and a top cover 13. The inner liner of the freezer compartment is located inside the main body. The top cover seals the top openings of the main body and the electrical cavity cover. The top cover has a freezer compartment opening 131, a first mounting base 133 for mounting the touch screen, and the battery compartment. The first mounting base has a rectangular frame 135, corner plates 136 are provided at the four corners of the rectangular frame, the bottom of the rectangular frame is connected to the electrical cavity, and screw posts 137 are provided on the periphery of the rectangular frame. The top of the screw posts is connected to the lower surface of the top cover 13, and the main control board is mounted on the lower end of the screw posts.

[0022] The main housing is surrounded by side panels, electrical cavity cover, and top cover to form an electrical cavity. The compressor, condenser, and cooling fan are installed inside the electrical cavity. The compressor's frequency converter 61, battery management board 62, and auxiliary control board 63 are installed on the side panels of the main housing.

[0023] like Figure 6 As shown, this utility model is equipped with two batteries, the main control board is electrically connected to the display screen, the main control board is electrically connected to the auxiliary control board 63, and the frequency converter 61 is connected to the compressor drive.

[0024] The working principle of this utility model:

[0025] When this invention is in operation, after the user presses the power switch, the battery powers the refrigeration system, which then starts working. The compressor and cooling fan begin to start, and the evaporator begins to cool, causing the temperature of the freezer compartment to decrease until the set refrigeration temperature is reached, and then the temperature of the freezer compartment is maintained. The cooling fan dissipates heat from the compressor and condenser. Cold air enters the electrical cavity through the air inlet, carrying away the heat from the compressor and condenser, and then exits the electrical cavity through the air outlet.

[0026] 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.

[0027] 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.
