Description

Technical Field

[0001] This invention relates to the field of refrigerator technology, and in particular to a four-way mounting shaft, a vehicle-mounted refrigerator door, and a vehicle-mounted refrigerator control method. Background Technology

[0002] Flip-top car refrigerators are typically placed in the armrest area inside the vehicle. The flip-top allows two passengers seated next to the armrest to easily open the refrigerator. The refrigerator can be located in the driver's side armrest or the rear armrest. However, due to space constraints and seat placement, opening the refrigerator door can be inconvenient. Most common designs on the market open in one direction or symmetrically in two directions.

[0003] The problem with existing technology is that when the opening position of the refrigerator door is restricted by items or passengers, the opening direction cannot be changed, making it inconvenient for passengers to take out items. Summary of the Invention

[0004] To solve the above-mentioned technical problems, the purpose of this invention is to provide a four-way mounting shaft that can be opened in four directions, a vehicle refrigerator, and a control method thereof.

[0005] The technical solution adopted by this invention to solve the problem is: a four-way mounting shaft, comprising:

[0006] A driving component, the driving component including a protrusion, the orientation of the protrusion being switchable in the up, down, left, and right directions;

[0007] The drive unit is provided with transmission components in the upper, lower, left and right directions, and a rotating shaft base is provided between two adjacent transmission components;

[0008] The transmission assembly includes a drive plate and a rotating shaft. The drive plate is provided with two mirror-arranged inclined slots, which are connected to the rotating shaft. The rotating shaft base is detachably connected to the rotating shaft. The protrusion of the drive component is used to push the drive plate to translate, thereby driving the rotating shaft to connect with the rotating shaft base.

[0009] A reset spring is connected to the drive plate. The reset spring is used to pull the drive plate to move horizontally, thereby driving the rotating shaft to disengage from the rotating shaft base.

[0010] Rotating the drive component in a certain direction controls the drive plate in that direction to move upwards. A slanted groove converts the vertical movement of the drive plate into the horizontal movement of the rotating shaft, causing it to insert into and be fixed in the shaft base. At this point, the door can rotate and open around the shaft in that direction. When the drive component changes direction, the drive plate in that direction is reset by a return spring, and the shaft disengages from the shaft base. Therefore, by changing the rotating shaft used for rotation, the refrigerator door can be opened from top, bottom, left, and right, making it convenient to use.

[0011] As a further improvement to the above technical solution, the driving component includes a cam and a handle, with the protrusion disposed on the cam and the handle disposed on the top of the cam. The protrusion is used to lift the driving plate, and the handle facilitates user control of the rotation of the driving component.

[0012] As a further improvement to the above technical solution, the top end of the rotating shaft is provided with a locking protrusion, which is slidably connected within an inclined groove. The outer end of the rotating shaft is provided with an insertion part, and the base of the rotating shaft is provided with an insertion hole. The insertion part is adapted to the insertion hole. The locking protrusion and the inclined groove are adapted to facilitate the conversion of the force direction of the drive plate, and at the same time facilitate worker installation and positioning.

[0013] A vehicle-mounted refrigerator door includes a four-way mounting shaft as described above, and a base plate. The base plate has a mounting cavity, and the transmission assembly is disposed within the mounting cavity. The upper part of the rotating shaft base is disposed within the mounting cavity. A clearance groove is provided on the drive plate, and a return spring is located within the clearance groove and fixedly connected to the base plate. The base plate supports and mounts the transmission assembly and the rotating shaft base, and the clearance groove is used to mount the return spring, enabling the drive plate to return to its original position.

[0014] As a further improvement to the above technical solution, a face cover is also included. The face cover has a mounting through hole, and the face cover is fitted onto the top of the base plate. The cam is shielded inside the face cover, and the handle is located inside the mounting through hole. The face cover protects the internal structure and prevents dust, while the handle located outside the face cover allows the user to rotate the drive component.

[0015] A vehicle refrigerator includes a vehicle refrigerator door as described above, and also includes an outer shell, an inner liner, and a sealing frame. The inner liner is fitted inside the outer shell, and the sealing frame is located on top of the outer shell and the inner liner. The rotating shaft base is fixedly connected to the sealing frame.

[0016] The present invention also provides a control method for a vehicle-mounted refrigerator, used in the vehicle-mounted refrigerator described above, wherein directions a and b are any two of the directions up, down, left, and right, and the method includes the following steps:

[0017] S1. The orientation of the protrusion of the switching drive component is in direction a. The drive component lifts the drive plate located in direction a. The rotating shafts on both sides of the drive plate located in direction a slide along the inclined groove and move away from each other, and are inserted into the rotating shaft bases set at both ends. At this time, the rotating shafts in the other three directions are not connected to the rotating shaft bases. The car refrigerator door can be rotated and opened around the rotating shaft in direction a.

[0018] S2. When the protrusion of the switching drive unit is oriented in direction b, the drive plate located in direction a is reset under the force of the reset spring, and the rotating shaft is disengaged from the rotating shaft base.

[0019] The drive unit lifts the drive plate located in direction b. The rotating shafts on both sides of the drive plate in direction b slide along the inclined groove and move away from each other, inserting into the rotating shaft bases set at both ends. At this time, the rotating shafts in the other three directions are not connected to the rotating shaft bases, and the vehicle refrigerator door can be rotated and opened around the rotating shaft in direction b.

[0020] The beneficial effects of this invention are: it provides a four-way mounting shaft, a vehicle refrigerator door, and a vehicle refrigerator control method, which is equipped with a drive component and a transmission assembly. By rotating the drive component, different rotating shafts are connected to the rotating shaft base, thereby changing the rotation shaft of the refrigerator door, so that the refrigerator door can be opened in different directions (up, down, left, and right), making it convenient and quick for users to open the refrigerator door from different directions to take out items.
