Description

Technical Field

[0001] This invention relates to the field of vehicle refrigerator technology, and more particularly to a shelf mechanism for a vehicle refrigerator. Background Technology

[0002] A car refrigerator is a small refrigeration device that can be used inside a car. It is typically used to keep food and drinks fresh and cool during long trips, camping, or outdoor activities. Car refrigerators provide cooling by using the vehicle's power source or a dedicated battery, allowing you to enjoy cold drinks and keep food fresh on the go.

[0003] When a car suddenly accelerates or decelerates while driving, food or drinks inside the car refrigerator are easily thrown up by inertia and hit the inner wall or door, thus scratching the inner wall or door.

[0004] This invention is based on the above circumstances. Summary of the Invention

[0005] This invention overcomes the shortcomings of the prior art and provides a shelf mechanism for a car refrigerator that can prevent food or beverages inside the refrigerator from being thrown up and hitting the inner wall or door due to inertia when the car suddenly accelerates or decelerates.

[0006] This invention is achieved through the following technical solution:

[0007] A shelf mechanism for a vehicle-mounted refrigerator includes a refrigerator body that can be installed in a vehicle and a control chip. The refrigerator body has an inner liner, and a rotating frame that can rotate is connected to the inner cavity of the inner liner. The rotating frame has a storage tray for placing items. The inner liner has a drive assembly that can drive the rotating frame to rotate. The inner liner also has an inertial detection device that can detect speed changes during vehicle movement and send signals to the control chip to control the operation of the drive assembly. A limiting structure is also provided between the rotating frame and the inner liner to limit the rotation range of the rotating frame.

[0008] As described above, the shelf mechanism of a vehicle refrigerator includes a drive assembly comprising a motor, a drive gear, a driven gear, and a transmission shaft. The motor is connected to the inner liner, the transmission shaft is fixedly connected to a rotating frame, the drive gear is connected to the output shaft of the motor, and the driven gear is connected to the transmission shaft and meshes with the drive gear.

[0009] The inertial detection device in the shelf mechanism of the vehicle refrigerator described above includes an inertial detection unit.

[0010] As described above, in a vehicle refrigerator shelf mechanism, the side of the inner liner used for mounting the motor is a mounting surface, and the limiting structure includes an arc-shaped limiting hole provided on the mounting surface, and a slider provided on the rotating frame and extending into the arc-shaped limiting hole.

[0011] As described above, the shelf mechanism of a vehicle refrigerator includes a first arc-shaped limiting hole located at the front of the mounting surface and a second arc-shaped limiting hole located at the rear of the mounting surface. The centers of the first and second arc-shaped limiting holes coincide. The slider includes a first slider located at the front end of the rotating frame and a second slider located at the rear end of the rotating frame. When the rotating frame rotates and the first slider abuts against the upper end of the first arc-shaped limiting hole, the second slider abuts against the lower end of the second arc-shaped limiting hole. When the rotating frame rotates and the first slider abuts against the lower end of the first arc-shaped limiting hole, the second slider abuts against the upper end of the second arc-shaped limiting hole.

[0012] As described above, the shelf mechanism of a vehicle refrigerator includes an outer frame and a base plate. The outer frame and the base plate form a placement slot for placing items. A movable partition that can adjust the width of the placement slot is also slidably connected to the outer frame.

[0013] As described above, in a vehicle refrigerator shelf mechanism, a first reset member is provided between the movable partition and the outer frame to reset the movable partition.

[0014] As described above, in a vehicle refrigerator shelf mechanism, the movable partition plate is provided with a plurality of first protrusions extending into the placement slots, and the inner sidewall of the outer frame is provided with second protrusions corresponding to the first protrusions.

[0015] As described above, the shelf mechanism of a vehicle refrigerator includes an inlet for placing items into the inner liner and a door for sealing the inlet. A lock hole is provided on the side wall of the inlet. A rotating block that can extend into the lock hole to lock the door is rotatably connected to the door, and a lifting lug that drives the rotating block to flip so that the rotating block exits the lock hole. A second reset member is also provided between the rotating block and the door to reset the rotating block and allow it to extend back into the lock hole.

[0016] As described above, in a vehicle refrigerator shelf mechanism, the door is provided with a first insulation layer for heat insulation, and the inner liner and the refrigerator body are provided with a second insulation layer for heat insulation.

[0017] Compared with the prior art, the present invention has the following advantages:

[0018] 1. The inner liner is equipped with an inertial detection device, which can detect the speed change of the car during driving and send a signal to the control chip to control the drive component to drive the rotating frame to rotate. This decomposes the supporting force of the storage tray on the items into a component force that cancels out the gravity and a component force that is in the same direction as the acceleration, so that the items are in a balanced state. This prevents the items in the car refrigerator from flying up and hitting the inner liner wall or the door due to inertia.

[0019] 2. This case uses a motor and gears for transmission, which is relatively stable and not easily affected by the inertia of the car during driving.

[0020] 3. The rotation range of the rotating frame is limited by the arc-shaped limiting hole, thereby preventing the rotation angle from being too large. At the same time, it can also guide the rotation of the rotating frame and provide rotation stability.

[0021] 4. A movable partition plate that can adjust the width of the placement slot is also slidably connected to the outer frame. The width of the placement slot can be adjusted according to the length of the beverage bottle. A pre-tightening force is applied to the beverage bottle through the first reset member and the movable partition plate to further prevent the beverage bottle from flying up due to changes in the speed of the car.

[0022] 5. The door is equipped with a first insulation layer for heat insulation, and the inner liner is equipped with a second insulation layer for heat insulation between the refrigerator body and the refrigerator body. The refrigerator is also equipped with insulation layers on all four sides, thereby improving the heat insulation effect of the refrigerator. Attached Figure Description

[0032] The present invention will now be further described with reference to the accompanying drawings:

[0033] like Figures 1 to 8 The illustrated vehicle refrigerator shelf mechanism includes a refrigerator body 1 that can be installed in a car and a control chip 2. The refrigerator body 1 has an inner liner 3 inside, and a rotating frame 4 that can rotate is connected to the inner cavity of the inner liner 3. The rotating frame 4 has a storage tray 41 for placing items. The inner liner 3 has a drive assembly that can drive the rotating frame 4 to rotate. The inner liner 3 also has an inertial detection device 5 that can detect speed changes during the car's movement and send signals to the control chip 2 to control the operation of the drive assembly. A limiting structure is also provided between the rotating frame 4 and the inner liner 3 to limit the rotation range of the rotating frame 4.

[0034] This device can detect speed changes during vehicle operation using inertial detection device 5 and send signals to control chip 2 to control drive assembly to rotate frame 4. This decomposes the supporting force of storage tray 41 on items into a component force that cancels out gravity and a component force that is in the same direction as acceleration, thus keeping items in a balanced state and preventing items in the car refrigerator from flying up and hitting the inner wall 3 or door due to inertia.

[0035] In one embodiment, the drive assembly includes a motor 61, a driving gear 62, a driven gear 63, and a transmission shaft 64. The motor 61 is connected to the inner liner 3, the transmission shaft 64 is fixedly connected to the rotating frame 4, the driving gear 62 is connected to the output shaft of the motor 61, and the driven gear 63 is connected to the transmission shaft 64 and meshes with the driving gear 62. Specifically, a mounting bracket can be provided on the inner liner 3 to mount the motor. The mounting bracket can be a U-shaped bracket, and a clearance space for the driving gear 62 is formed between the mounting bracket and the outer wall of the inner liner 3. The transmission shaft 64 is rotatably connected to the inner liner 3 via a bearing seat. The transmission via the motor 61 and gears is relatively stable and less susceptible to the influence of inertia during vehicle operation.

[0036] Specifically, depending on the installation position of the car refrigerator in the car, the drive shaft 64 can be designed to be arranged along the front and rear direction of the refrigerator body 1, or it can be designed to be arranged along the front and rear direction of the refrigerator body 1, so that the rotating frame 4 can rotate along the front and rear direction of the car. When the inertial detection device 5 detects that the car is accelerating, the rear end of the rotating frame 4 rotates upward. When the inertial detection device 5 detects that the car is decelerating, the front end of the rotating frame 4 rotates upward, so that the items are in a balanced state.

[0037] The aforementioned inertial detection device 5 can be an inertial detection unit, or it can be a balancer or accelerometer, or other devices for detecting acceleration.

[0038] The inner liner 3 has a mounting surface 31 on the side for mounting the motor 61. The front of the mounting surface 31 is provided with a first arc-shaped limiting hole 311, and the rear of the mounting surface 31 is provided with a second arc-shaped limiting hole 312. The centers of the first arc-shaped limiting hole 311 and the second arc-shaped limiting hole 312 coincide. The front end of the rotating frame 4 is provided with a first slider 42 that extends into the first arc-shaped limiting hole 311, and the rear end of the rotating frame 4 is provided with a second slider 43 that extends into the second arc-shaped limiting hole 312. When the rotating frame 4 rotates and the first slider 42 abuts against the upper end of the first arc-shaped limiting hole 311, the second slider 43 abuts against the lower end of the second arc-shaped limiting hole 312. When the rotating frame 4 rotates and the first slider 42 abuts against the lower end of the first arc-shaped limiting hole 311, the second slider 43 abuts against the upper end of the second arc-shaped limiting hole 312. The rotation range of the rotating frame 4 is limited by the first arc-shaped limiting hole 311 and the second arc-shaped limiting hole 312, thereby preventing the rotation angle from being too large. At the same time, the rotation of the rotating frame 4 can be guided and the rotation stability can be provided.

[0039] The storage tray 41 includes an outer frame 411 and a base plate 412. The outer frame 411 and the base plate 412 form a placement slot 417 for placing items. A movable partition 413, which can adjust the width of the placement slot 417, is slidably connected to the outer frame 411. A first reset member 414 is provided between the movable partition 413 and the outer frame 411 to reset the movable partition 413. The width of the placement slot 417 can be adjusted according to the length of the beverage bottle. A pre-tightening force is applied to the beverage bottle through the first reset member 414 and the movable partition 413 to further prevent the beverage bottle from flying off due to changes in the speed of the vehicle.

[0040] In one embodiment, the storage tray 41 can be mounted on the rotating frame 4 using threaded fasteners, or it can be connected to the rotating frame 4 by snap-fit, welding, or other methods. The outer frame 411 and the movable partition 413 are slidably connected by guide holes and pins, or they can be slidably connected by slide rails or other methods. The first reset member 414 can be a reset spring, or it can be other elastic reset members.

[0041] The movable partition 413 is provided with a plurality of first protrusions 415 extending into the placement groove 417, and the inner sidewall of the outer frame 411 is provided with second protrusions 416 corresponding to the first protrusions 415. When an aluminum can is placed in, the first protrusions 415 and the second protrusions 416 can extend into the recesses at the front and rear ends of the aluminum can, thereby further fixing the aluminum can. When an ordinary beverage bottle is placed in, the first protrusions 415 and the second protrusions 416 can form a bottle placement area, thereby restricting the left and right sliding of the bottle and reducing collisions between bottles.

[0042] The refrigerator body 1 is also provided with an inlet 10 for placing items into the inner liner 3 and a door 7 for sealing the inlet 10. A lock hole 101 is provided on the side wall of the inlet 10. A rotating block 81 is rotatably connected to the door 7, which can extend into the lock hole 101 to lock the door 7, and a lifting lug 82 that drives the rotating block 81 to rotate and thus disengage from the lock hole 101. A second reset member 83 is also provided between the rotating block 81 and the door 7 to reset the rotating block 81 and allow it to re-enter the lock hole 101. The second reset member 83 can be a torsion spring, making the opening and closing of the door 7 very convenient and quick.

[0043] The door 7 is provided with a first insulation layer 71 for heat insulation, and the inner liner 3 is provided with a second insulation layer 9 for heat insulation between the refrigerator body 1 and the refrigerator body 3. The refrigerator body is provided with insulation layers on all four sides, thereby improving the heat insulation effect of the refrigerator body.

[0044] In one embodiment, the inner liner 3 has openings at both ends, and the refrigerator body 1 has inlets 10 for placing items into the inner liner 3 and doors 7 for sealing the inlets 10 at both ends, so that people in different locations can open the car refrigerator to take out items from the car refrigerator.
