Description

A top-opening and rear-opening vehicle refrigerator and its control method Technical Field

[0001] The present invention relates to the field of vehicle-mounted refrigerators, and in particular to a top-opening and rear-opening vehicle-mounted refrigerator and a control method thereof. Background Art

[0002] Car refrigerators are generally opened by providing a top cover or a drawer, but the cover and the drawer are not provided at the same time.

[0003] A flip-top car refrigerator is usually placed on the armrest inside the car. The refrigerator flips back to make it easier for the two passengers sitting next to the armrest to open the refrigerator. The refrigerator can be placed on the armrest of the main driver's seat or on the rear armrest. For example, Chinese invention publication number CN203511399U discloses a rear armrest embedded refrigerator, which includes a box body with a refrigerator door hinged on the top of the box body. The refrigerator door can be flipped back to reveal the items inside the box. This structure is set at the main driver's seat to make it convenient for the front passengers to take items out of the refrigerator, but it is inconvenient for the rear passengers to take items; if this structure is set at the rear armrest, it will be difficult for the front passengers to take items from the refrigerator.

[0004] Drawer-style refrigerators are typically installed in the driver's seat armrest. The drawer slides out to facilitate access for rear-seat passengers. For example, Chinese Invention Publication No. CN217110130U discloses a vehicle-mounted refrigerator equipped with a quick-release drawer mechanism. The refrigerator assembly includes an inner container, and the drawer engages with the container via guide rails. This design makes it difficult for front-seat passengers to access items.

[0005] The problem with the existing technology is that it is not possible to facilitate passengers in the front and rear rows to take items at the same time.

[0006] Summary of the Invention

[0007] In order to solve the above technical problems, the purpose of the present invention is to provide a top-opening and rear-opening vehicle refrigerator and a control method thereof, which can facilitate both front and rear passengers to take items.

[0008] The technical solution adopted by the present invention to solve the problem is: a top-opening and rear-opening car refrigerator, including a box body, the top and rear ends of the box body are both provided with openings; a top cover is provided at the opening at the top end of the box body; and also includes a drawer, the drawer including a main body and a drawer panel, a accommodating cavity is provided in the box body, the main body is arranged in the accommodating cavity and is connected to the box body in a front-rear sliding manner, and the drawer panel cover is connected to the opening at the rear end of the box body.

[0009] As a further improvement to the above technical solution, the rear end of the top cover is hingedly connected to the box body, and the front portion of the top cover is provided with a connecting portion, and the box body is provided with a lock, and the lock is detachably connected to the connecting portion. In this technical solution, the top cover flips backward. When the top-opening and rear-opening car refrigerator of the present invention is installed in the front row, it opens backward without hindering the driver from driving the vehicle.

[0010] As a further improvement of the above technical solution, the lock includes a lock tongue and a power mechanism. The box body is provided with a first sensor, the first sensor is used to sense whether the drawer is open, and also includes a controller. The first sensor and the power mechanism are both electrically connected to the controller, and the power mechanism is used to drive the lock tongue to connect with or disconnect from the connecting part. Whether the drawer is open is sensed by the first sensor. When the drawer is open, the controller controls the Dongli mechanism to drive the lock tongue to connect with the connecting part, so that the user cannot open the top cover, thereby preventing the drawer and the top cover from being opened at the same time. If the top cover is opened when the drawer of the car refrigerator is open, the structures such as the drawer slide rail and the refrigeration system in the accommodating cavity are exposed, and foreign objects falling from the opening at the top of the box body may cause damage to the car refrigerator.

[0011] As an optional technical solution, the first sensor is a Hall sensor, the power mechanism is an electromagnet, and the connecting part is a blind hole. The power mechanism can attract or repel the lock tongue to control the translation of the lock tongue relative to the connecting part, so that the lock tongue is plugged into or detached from the connecting part.

[0012] As a further improvement of the above technical solution, a connecting position is provided on the drawer, and a buckle is provided on the box body, and the buckle is detachably connected to the connecting position.

[0013] As a further improvement of the above technical solution, the buckle includes a latch and a driving mechanism. The box body is provided with a second sensor, which is used to sense whether the top cover is open. It also includes a controller. The second sensor and the driving mechanism are electrically connected to the controller, and the driving mechanism is used to drive the latch to connect or disconnect with the connecting position.

[0014] As a further improvement to the above technical solution, the lock includes a locking pin and an elastic member connected to each other, wherein the locking pin is slidably mounted on the box body, and the spring member is fixedly mounted within the box body; when the drawer is open, the elastic member naturally extends, and the locking pin engages with the connecting portion; when the drawer is closed, the body presses against the locking pin, the elastic member is compressed, and the locking pin is disconnected from the connecting portion. When the drawer is closed, the locking pin is disconnected from the connecting portion, allowing the user to freely open the top cover; when the drawer is open, the locking pin engages with the connecting portion, preventing the user from opening the top cover.

[0015] The present invention also provides a control method for a top-opening and rear-opening vehicle refrigerator, wherein in an initial state of the vehicle refrigerator, the top cover and the drawer are both closed; when the first sensor detects that the top cover is open, the controller controls the drive mechanism to drive the latching protrusion to connect with the connecting position; when the first sensor detects that the top cover is closed, the controller controls the drive mechanism to drive the latching protrusion to disconnect from the connecting position; when the second sensor senses that the drawer is open, the controller controls the power mechanism to drive the locking tongue to connect with the connecting portion; when the second sensor senses that the drawer is closed, the controller controls the power mechanism to drive the locking tongue to disconnect from the connecting portion. The first sensor and the second sensor respectively sense the opening and closing states of the top cover and the drawer, thereby controlling the drive mechanism and the power mechanism through the controller to control the opening and closing states of the top cover and the drawer, thereby preventing the top cover and the drawer from being opened at the same time.

[0016] The beneficial effects of the present invention are as follows: the top of the box body can be opened through the top cover, and the rear end of the box body can be opened through the drawer. The top-opening and rear-opening car refrigerator of the present invention makes it convenient for passengers on the left, right and rear sides to take out items, that is, it is convenient for passengers in two rows to take items in the box at the same time.
