[0026] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] like Figure 1-8As shown, this invention provides a fully automatic drawer-type vehicle refrigerator, including a refrigerator body 1. A drawer component 2 is provided inside the refrigerator body 1, and the drawer component 2 can extend and retract from one end of the refrigerator body 1. A refrigerator liner 3 is provided inside the drawer component 2. An automatic drawer drive module 4 is detachably installed at the lower end of the refrigerator body 1. The automatic drawer drive module 4 includes a housing 46 and a horizontally sliding platform 51 installed on the top of the housing 46. The mobile platform 51 is connected to the drawer component 2. A power element 41 is installed at one end inside the housing 46. The output end of the power element 41 is connected to a horizontally arranged transmission rod 43 inside the housing 46. A threaded transmission block 42 is sleeved on the transmission rod 43. The transmission block 42 is connected to the mobile platform 51. A door lock assembly is installed on the bottom inner side of the housing 46 near the power element 41. The door lock assembly cooperates with the transmission rod 43 to keep the drawer component 2 in the retracted position inside the refrigerator body 1.

[0028] Specifically, the power element 41 can be a motor, which can precisely control the rotation of the transmission rod 43. The transmission rod 43 can be a lead screw. The transmission block 42 and the transmission rod 43 are connected by a thread. The transmission block 42 and the outer casing 46 are anti-rotation fits. The translation of the transmission block 42 can be achieved by rotating the transmission rod 43.

[0029] The movable platform 51 is flat and can stably support the drawer component 2. The upper two sides of the outer shell 46 are provided with grooves 55 along its length. A guide rail 48 is installed on one side of the inner side of the groove 55. The lower side of the movable platform 51 is provided with a connecting plate 49 that is embedded in the groove 55 and connected to the guide rail 48. The groove 55 can guide and limit the movement of the connecting plate 49, allowing the movable platform 51 to bear greater weight and making it less likely to derail.

[0030] Meanwhile, to facilitate the installation of the automatic drawer drive module 4, the outer side of the outer shell 46 is connected to the refrigerator body 1 by multiple clips 7, which enables the installation of the outer shell 46. In order to control the extension and retraction of the drawer component 2, the two ends of the transmission rod 43 are respectively provided with a first contact sensor 47 and a second contact sensor 44. When the transmission block 42 is in contact with the door lock assembly, it contacts the first contact sensor 47. When the transmission block 42 moves to a position away from the power element 41, it contacts the second contact sensor 44.

[0031] The door lock assembly includes a vertically arranged spring 52, with a locking block 53 mounted on its upper end. The locking block 53 engages with a groove at the lower end of the transmission block 42. One end of the transmission rod 43 is connected to the input end of the power element 41 via a coupling 54, and the other end of the transmission rod 43 is connected to the housing 46 via a transmission rod support 44.

[0032] The vehicle refrigerator also includes an electronic control unit 8, installed at the rear end of the drawer component 2. The power element 41, the first contact sensor 47, and the second contact sensor 44 are all electrically connected to the electronic control unit 8. The electronic control unit 8 can issue commands, and the automatic drawer drive module 4 receives the commands. The power element 41 generates rotational power, which is transmitted to the transmission rod 43. The transmission rod 43 is supported by the transmission rod support 44 fixed to the outer shell 46 to reduce swaying. A transmission block 42 is then installed on the transmission rod 43. Under the action of the outer shell 46, the transmission block 42 moves in a straight line in the direction of the arrow. The mechanism moves back, and the transmission block 42 is connected to the moving platform 51 to transmit power. The load of the moving platform 51 is borne by the guide rail 48, which is fixed to the outer shell 46, producing a smooth linear motion until it touches the first contact sensor 47 and stops moving. The mechanism is in the locked state, and the locking is provided by the spring 52, which acts on the locking block 53. The locking block 53 transmits the pressure to the transmission block 42, thereby generating a locking force. In the extended state, the mechanism is in the maximum open state. When the transmission block 42 touches the second contact sensor 44, the mechanism stops running, and the refrigerator is in the maximum open state.

[0033] The rear end of the drawer component 2 is provided with a compressor module mounting cavity 5, and a compressor module 6 is installed in the compressor module mounting cavity 5, which facilitates the installation, protection and maintenance of the compressor module 6.

[0034] In addition, such as Figure 9-10As shown, an embodiment of the present invention also provides a control unit for a fully automatic drawer-type car refrigerator, including a main controller 11, a heating module 12, an auxiliary heating module 13, a compressor module 6, a circulating fan 1FAN1, a circulating fan 2FAN2, a MOT module 15, a Hall lamp control module 16, an ultraviolet germicidal lamp UV-C, a temperature sensor 1NTC1, a temperature sensor 2NTC2, and a temperature sensor 3NTC3. The power supply terminal and control signal terminal of the main controller 11 are respectively connected to the power supply and the protocol bus, and the signal acquisition terminal of the main controller 11 is connected to the temperature sensor 1NTC1, the temperature sensor 2NTC2, and the temperature sensor 3NTC3 respectively; the execution signal output terminal of the main controller 11 is respectively connected to the heating module 12, the auxiliary heating module 13, and the compressor module 6. The refrigerator comprises a compressor module 6, a circulating fan 1 (FAN1), a circulating fan 2 (FAN2), a MOT module 15, a Hall effect lamp control module 16, and an ultraviolet germicidal lamp (UV-C). The MOT module 5 includes an MOT control circuit and a power element 41. The MOT control circuit is interconnected with the main controller 11, controlled by the main controller 11, and can autonomously identify and actively drive the refrigerator. The auxiliary heating module 3 is integrated inside the refrigerator door and the inner liner 3 for decondensation treatment. The circulating fans 1 (FAN1) and 2 (FAN2) are respectively located in the compressor radiator and the air circulation channel. The Hall effect lamp control module 16 and the ultraviolet germicidal lamp (UV-C) are both installed inside the inner liner 3. The auxiliary heating module 3 is a diaphragm or heating wire structure.

[0035] The working principle of this specific implementation is as follows: after the refrigerator control board receives the drawer drive command from the vehicle system or the refrigerator button panel, the operating power element 41 performs the specified action and feeds back the current status to the vehicle system.

[0036] A. If resistance is encountered during the process of opening or closing the drawer that exceeds the rated value, the drawer will retract to an appropriate length to prevent injury to the user, and at the same time, the relevant status will be fed back to the main control system.

[0037] B. When the drawer is in any stationary state, the system will execute the user's intended action if it detects that the pushing or pulling force is greater than the rated value.

[0038] The above embodiments improve the structure of the vehicle refrigerator and combine it with drawer-type drive logic to realize a drawer-type vehicle refrigerator. It can realize multi-channel control and has anti-pinch and intention-sensing drive functions, which greatly improves the safety and convenience of using the vehicle refrigerator.

[0039] It should be noted that all directional indicators (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative positional relationship and movement of each component in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicator will also change accordingly.

[0040] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0041] In this invention, unless otherwise explicitly specified and limited, the terms "connection," "fixed," etc., should be interpreted broadly. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral part; it can mean a mechanical connection or an electrical connection; it can mean a direct connection or an indirect connection through an intermediate medium; it can mean the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this invention according to the specific circumstances.

[0042] Furthermore, the technical solutions of the various embodiments of the present invention can be combined with each other, but only if they are feasible for those skilled in the art. If the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by the present invention.
