[0035] In some cases, for some car refrigerators, multiple doors are usually set up at the same time to facilitate users to take items out of the car refrigerator. However, for the current solution, the car refrigerator does not achieve linkage control of multiple doors. When one door is opened, another door can also open. Therefore, there are problems such as the door movement module being exposed, which is not aesthetically pleasing, or the movement module getting stuck when foreign objects fall in, which poses a risk that the door cannot close properly.

[0036] Based on the above, this application proposes a vehicle-mounted refrigerator and vehicle, which aims to control multiple refrigerator doors in a coordinated manner to prevent them from opening simultaneously, improve aesthetics, and reduce the risk of foreign objects falling and jamming the movement module.

[0037] The various embodiments of the vehicle-mounted refrigerator of this application will be further described below with reference to the accompanying drawings.

[0038] In one embodiment, such as Figures 1 to 6As shown, the vehicle refrigerator includes, but is not limited to, a cabinet 100, a first door 210, and a second door 300. The cabinet 100 is equipped with a transmission device, a sensor 810, and a movable latch 600. The first door 210 is movably mounted on one side of the cabinet 100 via a motion module 220. The motion module 220 is in contact with the transmission device and can drive the transmission device to move. One end of the transmission device is connected to the latch 600, meaning that the motion module 220 can pull the latch 600 through the transmission device. The second door 300 is provided with a socket 310 and is movably mounted on the other side of the cabinet 100. The latch 600 of the cabinet 100 is movably mounted in the socket 310 to prevent the second door 300 from rotating. In addition, the sensor 810 is located at the door frame of the cabinet 100 and is used to detect the open / closed state of the second door 300.

[0039] In one embodiment, the second door 300 can be locked from opening by inserting the latch 600 into the socket 310; conversely, the second door 300 can be unlocked by pulling the latch 600 out of the socket 310, at which point the second door 300 can be opened.

[0040] It is understood that the shape of the aforementioned latch 600 can be cylindrical, cuboid, or other shapes, and this application embodiment does not specifically limit it in this regard.

[0041] In one embodiment, when the first door 210 and the motion module 220 are in the first open position, the motion module 220 inserts the locking tongue 600 into the socket 310 via a transmission device to lock the second door 300 in the second closed position. Specifically, when the first door 210 is in the open state, the motion module 220 disengages from the abutting transmission device, and the transmission device, relying on its own elasticity, inserts the locking tongue 600 into the socket 310, thereby locking the second door 300 in the closed state and preventing the second door 300 from opening.

[0042] In one embodiment, when the second door 300 is in the second open position, the sensor 810 detects an opening trigger signal for the second door 300, and the first door 210 and the motion module 220 are locked in the first closed position in response to the opening trigger signal. Specifically, when the second door 300 is in the open state, the sensor 810 detects that the second door 300 is open and responds by locking the motion module 220 in a fixed state. At this time, the motion module 220 cannot move, thus preventing the first door 210 from opening.

[0043] In one embodiment, the first door 210 is a drawer-type door, and the first door 210 is installed on the side of the box 100. In addition, the motion module 220 can be a linear slide rail module, an electric push rod module, or other sliding modules. Therefore, the first door 210 can be pushed and pulled back and forth inside and outside the box 100 by the motion module 220.

[0044] In one embodiment, the second door 300 is a flip-up door, and the second door 300 is installed on the top surface of the housing 100. The second door 300 can be installed on the door frame of the housing 100 via hinges or other means.

[0045] In one embodiment, such as Figures 3 to 4 As shown, the transmission device includes, but is not limited to, a steering assembly and a transmission rope 500. The steering assembly is movably mounted on the housing 100, and one end of the steering assembly is connected to the locking tongue 600 via the transmission rope 500.

[0046] Specifically, when the first door 210 is in the open state, the motion module 220 disengages from the resisting steering component. The steering component rotates clockwise under its own elasticity, that is, it rotates in the direction of the transmission rope 500, which makes the transmission rope 500 slack, that is, it stops pulling the locking tongue 600 through the transmission rope 500. In this way, the locking tongue 600 can be passively inserted into the socket 310, thereby locking the second door 300 in the closed state and preventing the second door 300 from opening.

[0047] In addition, when the first door 210 is closed, the motion module 220 abuts against the steering component, causing the steering component to rotate counterclockwise, that is, to rotate away from the transmission rope 500, so that the transmission rope 500 is tightened, that is, the locking tongue 600 is pulled by the transmission rope 500, thereby causing the locking tongue 600 to disengage from the socket 310, thereby unlocking the second door 300, at which time the second door 300 can be opened freely.

[0048] In one embodiment, a column 430 may be provided inside the housing 100, and a steering component may be installed on the column 430, thereby enabling the steering component to rotate in a clockwise or counterclockwise direction.

[0049] In one embodiment, an independent transmission channel can be provided inside the housing 100, and the transmission rope 500 is installed in the transmission channel to ensure that the transmission rope 500 can move smoothly.

[0050] It is understood that the aforementioned transmission rope 500 can be a steel wire rope, an aluminum wire rope, or a transmission rope 500 made of other materials, and this application embodiment does not specifically limit it in this regard.

[0051] In one embodiment, such as Figure 4As shown, the transmission device also includes, but is not limited to, an elastic element 700, which is in contact with the locking tongue 600 and is used to press the locking tongue 600 toward the insertion hole 310.

[0052] In one embodiment, when the first door 210 and the motion module 220 are in the first open position, the motion module 220 disengages from the contact steering assembly, and the steering assembly rotates in the first rotation direction, causing the transmission rope 500 to slack. At this time, the elastic force of the elastic member 700 is greater than the pulling force of the steering assembly, so the elastic member 700 can press the latch 600 into the insertion hole 310.

[0053] Specifically, when the first door 210 is in the open state, the motion module 220 disengages from the abutting steering component. The steering component rotates clockwise under its own elasticity, that is, it rotates in the direction of the transmission rope 500, causing the transmission rope 500 to slack, that is, to stop pulling the locking tongue 600 through the transmission rope 500. Then, under the pressing action of the elastic member 700, the locking tongue 600 can be pressed into the insertion hole 310, thereby locking the second door 300 in the closed state and preventing the second door 300 from opening.

[0054] In one embodiment, when the first door 210 and the motion module 220 are in the first closed position, the motion module 220 presses against the steering assembly to rotate in the second rotation direction. At this time, the pulling force of the steering assembly is greater than the elastic force of the elastic element 700. Therefore, the steering assembly can pull the latch 600 out of the socket 310 through the transmission rope 500. The second rotation direction and the first rotation direction are opposite to each other.

[0055] Specifically, when the first door 210 is closed, the motion module 220 abuts against the steering component, causing the steering component to rotate counterclockwise, that is, to rotate away from the transmission rope 500, so that the transmission rope 500 is tightened, that is, the locking tongue 600 is pulled by the transmission rope 500, which in turn allows the locking tongue 600 to disengage from the socket 310, thereby unlocking the second door 300, at which point the second door 300 can be opened freely.

[0056] It is understood that the elastic element 700 mentioned above can be a spring, a sheet, or other elastic element 700, and the embodiments of this application do not specifically limit it.

[0057] In one embodiment, such as Figure 3 As shown, the steering assembly includes, but is not limited to, a steering block 410 and a torsion spring 420. The steering block 410 is movably mounted inside the housing 100, and the torsion spring 420 is mounted on the steering block 410.

[0058] In one embodiment, a column 430 may be provided inside the housing 100, and a steering block 410 and a torsion spring 420 are sleeved on the column 430, thereby enabling the steering block 410 to rotate in a clockwise or counterclockwise direction.

[0059] Specifically, when the motion module 220 presses against the steering block 410, since the pressure applied by the motion module 220 to the steering block 410 is greater than the torque applied by the torsion spring 420 to the steering block 410, the steering block 410 will rotate counterclockwise, that is, rotate away from the transmission rope 500, so that the locking tongue 600 can be pulled away from the socket 310 by the transmission rope 500.

[0060] In addition, when the motion module 220 does not press against the steering block 410, the steering block 410 will rotate clockwise under the action of the torsion spring 420, that is, rotate in the direction of the transmission rope 500, so that the transmission rope 500 is relaxed, that is, the locking tongue 600 is stopped being pulled by the transmission rope 500. Then, under the pressing action of the elastic member 700, the locking tongue 600 can be pressed into the socket 310, thereby locking the second door 300 in the closed state and preventing the second door 300 from opening.

[0061] In one embodiment, the motion module 220 is equipped with a motor, which is used to control the motion state of the motion module 220. Specifically, in this embodiment, the motor can be used to lock the motion module 220, preventing it from moving; alternatively, the motor can be used to unlock the motion module 220, allowing it to move.

[0062] In one embodiment, the motion module 220 may be equipped with a roller, and the motor is linked to the roller. Therefore, this embodiment can use the motor to control the roller, locking or unlocking it. Alternatively, the motion module 220 may be equipped with a locking hole, and the motor is connected to a pin via a transmission structure. When the motor inserts the pin into the locking hole via the transmission structure, the motion module 220 is locked; when the motor pulls the pin out of the locking hole via the transmission structure, the motion module 220 is unlocked.

[0063] In one embodiment, when the sensor 810 detects an opening trigger signal of the second door 300, the motor locks the motion module 220 according to the opening trigger signal. Specifically, when the second door 300 is in the open state, the sensor 810 detects the opening trigger signal of the second door 300 and sends it to the controller. Then, the controller controls the motor of the motion module 220 according to the opening trigger signal, thereby locking the motion module 220 and making the motion module 220 immobile.

[0064] In one embodiment, when the sensor 810 detects a closing trigger signal from the second door 300, the motor unlocks the motion module 220 according to the closing trigger signal. Specifically, when the second door 300 is in the closed state, the sensor 810 detects the closing trigger signal of the second door 300 and sends it to the controller. Then, the controller controls the motor of the motion module 220 according to the closing trigger signal, thereby unlocking the motion module 220 and allowing the motion module 220 to move.

[0065] In one embodiment, such as Figure 5 As shown, the sensor 810 in this embodiment can be a Hall sensor, which is installed at the door frame position of the housing 100; a magnet 820 is installed on the second door 300, and the position of the magnet 820 corresponds to the position of the Hall sensor. Specifically, based on the Hall effect, when the second door 300 is closed, the magnet 820 approaches the Hall sensor, thereby triggering the Hall sensor; when the second door 300 is open, the magnet 820 moves away from the Hall sensor, causing the signal to flip, thereby determining the state of the second door 300.

[0066] In addition, it should be noted that, in addition to using Hall effect sensors and magnets 820 to detect the opening and closing status of the second door 300, mechanical limit switches, distance sensors 810, etc. can also be used. This application embodiment does not specifically limit this method.

[0067] Based on the vehicle refrigerators of the above embodiments, the overall embodiment of the vehicle refrigerator of this application is presented below.

[0068] Specifically, when both the first door 210 and the second door 300 of the vehicle refrigerator are closed, the drawer pressure steering block 410 in the motion module 220 is in a designated position, and the locking tongue 600 is pulled back through the transmission rope 500, so that the second door 300 is in an openable state.

[0069] When the second door 300 is opened, the Hall sensor does not detect the magnetic flux of the magnet 820. At this time, it will send a signal to the controller to prevent the first door 210 from being opened. At this time, the driver and passengers can take items from the upper level and the drawer.

[0070] When the first door 210 is opened, the drawer releases the restriction on the turning block 410. The turning block 410 rotates under the action of the torsion spring 420, the transmission rope 500 moves upward, and the locking tongue 600 pops out under the action of the spring and locks into the insertion hole 310 of the second door 300, thereby preventing the second door 300 from being opened.

[0071] Based on the vehicle refrigerators of the above embodiments, the following presents various embodiments of the vehicle of this application.

[0072] One embodiment of this application also provides a vehicle, which includes, but is not limited to, the vehicle-mounted refrigerator of any of the above embodiments.

[0074] The above provides a detailed description of the preferred embodiments of this application. However, this application is not limited to the above-described embodiments.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
