Abstract
Description
Technical Field
[0001] This utility model belongs to the field of vehicle refrigerator technology, specifically relating to an opening and closing structure for a vehicle refrigerator door. Background Technology
[0002] With the improvement of automotive intelligence and functionality, and to make travel more convenient and outdoor activities more possible, more and more users are choosing to equip their cars with in-vehicle refrigerators, similar to household refrigerators and commercial freezers. The doors of in-vehicle refrigerators on the market are generally manually opened from both sides or one side. Since there is no limit switch, when the refrigerator door is opened, the door will hit the refrigerator body, which can easily cause damage and deformation of the door hinges, damage to the appearance of the refrigerator, and greatly affect the insulation and hygiene of the in-vehicle refrigerator.
[0003] Currently, car refrigerators on the market fall into three main categories: energy storage car refrigerators, semiconductor car refrigerators, and compressor car refrigerators. Energy storage car refrigerators do not use the car's power supply and only have a heat preservation function, with a relatively short heat preservation time. Semiconductor car refrigerators, while capable of cooling or heating, have a limited cooling temperature range, generally not reaching below zero degrees Celsius, and their cooling effect is greatly affected by environmental factors. In contrast, compressor car refrigerators overcome the shortcomings of the former two, but they are more expensive, and there is still room for optimization in their structure and function. Utility Model Content
[0004] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:
[0005] An opening and closing structure for a vehicle-mounted refrigerator door includes a refrigerator and a door, which are connected by the opening and closing structure. The refrigerator opens and closes the door through the opening and closing structure. The opening and closing structure includes at least two sets of hinge assemblies and an electric assembly. The electric assembly is connected to the hinge assemblies through a drive assembly. The hinge assembly also includes a blocking assembly. The electric assembly drives the door to open and close through the drive assembly.
[0006] Furthermore, the drive assembly includes at least one set of driving gears and one set of driven gears, and also includes at least one set of drive shafts. The driving gears are fixed to the output end of the electric assembly, the driven gears are sleeved on the drive shafts, and the two ends of the drive shafts are respectively connected to two sets of hinge assemblies through blocking assemblies.
[0007] Furthermore, the blocking component is fixedly connected to the drive shaft. The blocking component has a protrusion, and the hinge component has a groove. The protrusion enters the groove for engagement. When the drive shaft rotates, the blocking component can drive the hinge component to rotate.
[0008] Furthermore, a limiting component is also fixed on the refrigerator. The limiting component is used to limit the drive component, and the drive gear and drive shaft are rotatably connected to the limiting component.
[0009] Furthermore, the electric component is a motor.
[0010] Furthermore, the hinge assembly is divided into a first hinge and a second hinge, the first hinge and the second hinge are rotatably connected, the first hinge is fixedly connected to the refrigerator, and the second hinge is fixedly connected to the door.
[0011] The beneficial effects of this utility model are:
[0012] This invention optimizes the structure of a compressor-type vehicle refrigerator, giving it automation and intelligence. Through a coupling gear and motor transmission device, the coupling is fixedly connected to the refrigerator door hinge. When power is connected, the gear drives the door to rotate, achieving automatic opening and closing of the refrigerator door at a fixed angle. It has the advantage of a small footprint due to its gear transmission structure, and unlike automatic coupling devices, it can be hidden inside the refrigerator casing. It also achieves automatic opening and closing of the refrigerator door at a fixed angle.
