[0037] like Figures 1 to 5 As shown, Figures 1 to 5 The direction B in the middle represents the sliding direction of the drawer 20. The first aspect of the utility model proposes a vehicle-mounted refrigerator, including a refrigerating chamber 10, a drawer 20, a sensing device 40 and a driving device 30. The drawer 20 is slidably arranged in the refrigerating chamber 10. The sensing device 40 is used to sense the action of the drawer 20 being pushed and sliding into the refrigerating chamber 10. The driving device 30 is electrically connected to the sensing device 40 and is used to drive the drawer 20 to slide into the refrigerating chamber 10 according to the signal of the sensing device 40.

[0038] It is understood that a vehicle refrigerator is a refrigeration storage device installed inside a vehicle. The vehicle refrigerator has an outer shell, and a cold storage chamber 10 with an opening is formed within the outer shell. The cold storage chamber 10 creates a low-temperature environment for storing food. The shape of the drawer 20 is compatible with the cold storage chamber 10. The drawer 20 can be slidably connected to the cold storage chamber 10 to move in and out of the opening to open and close the drawer 20. To achieve automatic sliding of the drawer 20, the vehicle refrigerator is also equipped with a drive device 30. The motor 31 is connected to the drawer 20 to automatically drive the drawer 20 when it slides. The drawer 20 can be automatically opened by pressing a button on the vehicle refrigerator. In order to achieve automatic closing of the drawer 20, a sensing device 40 is further provided in the vehicle refrigerator, such as a micro switch 41, a photoelectric sensor, etc., which automatically controls the drawer 20 by sensing its movement. When the user pushes the drawer 20 to move into the refrigerator compartment 10, the sensing device 40 can sense the movement of the drawer 20 through a contact signal or a photoelectric signal, and then control the drive device 30 to automatically drive the drawer 20 to slide inward, so that the drawer 20 automatically closes. The user can push the drawer 20 by hand or foot, and the sensing device 40 can sense the movement of the drawer 20 without a large pushing action, making it easier for the user to close the drawer 20. Specifically, the outer surface of the drawer 20 can have a contact surface perpendicular to the sliding direction of the drawer 20, and the contact surface is arranged toward the opening, so that when the drawer 20 is in the open state, the contact surface can contact the micro switch 41. Then, when the drawer 20 moves inward, the contact surface leaves the micro switch 41, which is converted into an inward movement signal of the drawer 20. Alternatively, a sensing point cooperating with a photoelectric sensor is set on the outer surface of the drawer 20, and the photoelectric sensor captures the position signal of the sensing point and converts it into an inward movement signal of the drawer 20, thereby controlling the driving device 30 to drive the drawer 20 to slide.

[0039] The vehicle-mounted refrigerator proposed in the first aspect of the present invention is provided with a sensing device 40 to sense the movement of the drawer 20 sliding into the refrigeration chamber 10. The sensing device 40 can adopt a micro switch 41, a photoelectric sensor or a Hall sensor, etc., so that the user's slight movement of pushing the drawer 20 inward can be captured by the sensing device 40, and the sensing device 40 is electrically connected to the driving device 30. The driving device 30 automatically drives the drawer 20 to slide inward according to the inward sliding signal of the drawer 20 captured by the sensing device 40, so that the user's intention to close the drawer 20 is captured and automatically executed, thereby improving the user experience.

[0040] In some embodiments of the present invention, the drawer 20 has a contact portion 21, and the drawer 20 has a first position and a second position on the sliding path. In the first position, the drawer 20 is accommodated in the refrigerator compartment 10. In the second position, at least a portion of the drawer 20 is located outside the refrigerator compartment 10, and the contact portion 21 is in contact with the sensing device 40.

[0041] It can be understood that the outer surface of the drawer 20 may have a protruding contact portion 21, and the contact portion 21 may be a flat structure or a block structure. The contact portion 21 has a contact surface perpendicular to the sliding direction of the drawer 20. The contact surface is set toward the opening when the drawer 20 is in the first position, so that it can contact the sensing device 40 when the drawer 20 slides to the second position, and then when the drawer 20 slides to the first position, the contact portion 21 is separated from the sensing device 40, so that the sensing device 40 generates a signal that the drawer 20 slides inward, and controls the drive device 30 to drive the drawer 20 to automatically slide inward to the first position.

[0042] In some embodiments of the present invention, the sensing device 40 includes a micro switch 41 . The micro switch 41 has a sensing portion 42 . When the drawer 20 is in the second position, the contact portion 21 contacts the sensing portion 42 .

[0043] It can be understood that a micro switch 41 can be set to capture the signal of the drawer 20 sliding inward, and then the drive device 30 can be controlled to drive the drawer 20 to slide inward automatically. The micro switch 41 has a sensing plate. When the drawer 20 is in the second position, the contact portion 21 rests on the sensing plate. When the user pushes the drawer 20 inward, the pressure of the contact portion 21 on the sensing plate is weakened, and the micro switch 41 captures the tiny pressure signal change, and then controls the drive device 30 to drive the drawer 20 to automatically slide inward to the first position to help the user close the drawer 20.

[0044] In some embodiments of the present invention, the sensing device 40 is arranged at the opening of the refrigerating chamber 10. Along the sliding direction of the drawer 20, the drawer 20 has opposite first and second ends. When the drawer 20 is in the second position, the first end is located in the refrigerating chamber 10, and the second end extends out of the refrigerating chamber 10, and the contact portion 21 is arranged at the first end.

[0045] It can be understood that the sensing device 40 can be fixed at the opening, for example, arranged below the drawer 20 and installed on the wall of the refrigerator compartment 10. When the drawer 20 is opened and slides to the second position, the second end of the drawer 20 extends out of the refrigerator compartment 10, and the contact portion 21 is arranged at the first end of the drawer 20. The first end also slides to the opening and contacts the sensing device 40 or is sensed by the sensing device 40, so that the sensing device 40 senses the signal that the drawer 20 is opened. When the drawer 20 moves inward, the contact portion 21 moves in the direction away from the sensing device 40, and the sensing device 40 captures the position signal of the contact portion 21 again, thereby controlling the drive device 30.

[0046] In some embodiments of the present invention, the driving device 30 includes a motor 31 and a driving mechanism. The motor 31 is connected to the drawer 20 through the driving mechanism and is used to drive the drawer 20 to slide. The sensing device 40 includes an encoder, which is used to monitor the rotation of the motor 31.

[0047] It can be understood that the rotation of the motor 31 can be converted into the sliding of the drawer 20 through the transmission connection between the motor 31 and the drawer 20, so that the motor 31 drives the drawer 20 to slide in and out of the refrigerator compartment 10. The sensing device 40 may include an encoder arranged at the motor 31, and the encoder can sense the rotation of the motor 31. When the drawer 20 is pushed inward by the user, the movement of the drawer 20 is transmitted to the motor 31, and the rotating parts of the motor 31 follow the rotation. At this time, the encoder can sense the rotation action and then infer that the drawer 20 is pushed inward. The encoder controls the rotation of the motor 31 according to the received rotation signal, and then the motor 31 drives the drawer 20 to slide inward, thereby realizing automatic closing of the drawer 20.

[0048] In some embodiments of the present invention, the encoder is disposed on the circumference of the rotating shaft of the motor 31 .

[0049] It can be understood that the encoder can be installed on the side of the shaft of the motor 31 so that the rotation of the shaft can be captured by the encoder, and then the sensing device 40 controls the rotation of the motor 31 according to the received rotation signal, and then the motor 31 drives the drawer 20 to slide inward, so that the drawer 20 is automatically closed.

[0050] In some embodiments of the present invention, the driving device 30 includes a motor 31, a driving wheel 32, a driven wheel 33 and a belt 34. Along the sliding direction of the drawer 20, the driving wheel 32 and the driven wheel 33 are respectively arranged at opposite ends of the refrigeration chamber 10, the motor 31 is connected to the driving wheel 32, the driving wheel 32 is connected to the driven wheel 33 through the belt 34, and the drawer 20 is fixedly connected to the belt 34.

[0051] It is understandable that the motor 31 can be set in the refrigerator compartment 10 and located at the end of the refrigerator compartment 10 away from the opening along the sliding direction of the drawer 20. The driving wheel 32 can be mounted on the rotating shaft of the motor 31, and the driven wheel 33 is arranged at the end of the refrigerator compartment 10 with the opening. The driven wheel 33 and the driving wheel 32 are connected by a belt 34. The belt 34 is respectively wound around the driving wheel 32 and the driven wheel 33. When the motor 31 rotates, it drives the driving wheel 32 to rotate, and then drives the driven wheel 33 to rotate through the belt 34. The bottom end of the drawer 20 can be fixedly connected to the belt 34 through a clamping structure, so that the belt 34 drives the drawer 20 to slide during movement. Specifically, a tensioning wheel 35 can also be provided between the driving wheel 32 and the driven wheel 33. The tensioning wheel 35 is located below the belt 34. The outer peripheral surface of the tensioning wheel 35 abuts against the belt 34, so that the belt 34 remains in a tensioned state, thereby reducing the phenomenon of the belt 34 slipping during movement and improving transmission efficiency.

[0052] In some embodiments of the present invention, the vehicle refrigerator further includes a slide rail 11 disposed in the refrigerating chamber 10 , the slide rail 11 extending along the sliding direction of the drawer 20 , and a slide groove 22 slidably connected to the slide rail 11 is formed on the outer surface of the drawer 20 ;

[0053] Alternatively, the vehicle refrigerator further includes a slide groove 22 arranged in the refrigerating chamber 10 , the slide groove 22 extends along the sliding direction of the drawer 20 , and a slide rail 11 slidably connected to the slide groove 22 is provided on the outer surface of the drawer 20 .

[0054] It is understandable that one or more slide rails 11 can be set in the refrigerator compartment 10. Specifically, a slide rail 11 can be set on each side of the refrigerator compartment 10, and a slide groove 22 can be set at the corresponding position of the drawer 20. The slide groove 22 slides with the slide rail 11, so that the drawer 20 is limited when sliding, reducing the phenomenon of the drawer 20 deviating from the path when sliding. The slide rail 11 and the slide groove 22 can be made of a material with low friction to reduce the resistance of the drawer 20 when sliding and improve the sliding efficiency. In addition, the positions of the slide groove 22 and the slide rail 11 can be interchanged, that is, the slide groove 22 is set in the refrigerator compartment 10, and the slide rail 11 is set at the corresponding position of the drawer 20, which can also achieve the effect of limiting the drawer 20 and reducing the sliding resistance.

[0055] A second aspect of the present invention provides a vehicle, comprising the vehicle-mounted refrigerator provided in the first aspect of the present invention.

[0056] It can be understood that the car refrigerator proposed in the present invention can be integrated with the vehicle, for example, it can be set in the armrest box in the front or rear row of the vehicle, or other locations with ample space, such as the glove box of the co-driver's seat, so that the interior of the vehicle is more beautiful, and the car refrigerator can conveniently utilize the vehicle's power supply and supporting systems, with a more compact structure and higher integration.

[0057] The interior of the vehicle proposed in the second aspect of the present invention is integrated with the vehicle refrigerator proposed in the first aspect of the present invention, and the vehicle refrigerator automatically executes the action of closing the drawer 20 by setting a sensing device 40 to capture the user's intention to close the drawer 20. The sensing device 40 can adopt a micro switch 41, a photoelectric sensor or a Hall sensor, etc., so that the user's slight action of pushing the drawer 20 inward can be captured by the sensing device 40, and the sensing device 40 is electrically connected to the driving device 30. The driving device 30 automatically drives the drawer 20 to slide inward according to the inward sliding signal of the drawer 20 captured by the sensing device 40, so that the user's intention to close the drawer 20 is captured and automatically executed, thereby improving the user experience.

[0058] In some embodiments of the present invention, the vehicle further includes an armrest box (not shown in the figures), and the vehicle refrigerator is installed in the armrest box.

[0059] It can be understood that the vehicle refrigerator proposed in the present invention is a front-mounted vehicle refrigerator, which is integrated in the armrest box, can make full use of the space in the armrest box, and is convenient for front and rear passengers to use.

[0060] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
