Description

Technical Field

[0001] The utility model relates to the field of vehicle-mounted equipment, in particular to a portable vehicle-mounted refrigerator. Background Art

[0002] Vehicle-mounted equipment refers to electronic equipment used in automobiles. Among them, vehicle-mounted refrigerators are widely used as appliances that can refrigerate or heat water or beverages carried by people when driving for tourism or participating in outdoor activities. However, in order to increase the volume, the existing vehicle-mounted refrigerators are usually of relatively large size. Such a setting causes the vehicle-mounted refrigerator to be placed in the trunk of the vehicle. If the final outdoor activity destination is far from the vehicle and there is a large amount of water or beverages in the vehicle-mounted refrigerator, it requires multiple people to carry it together, which is not only time-consuming and laborious but also reduces people's demand for using the vehicle-mounted refrigerator. Therefore, a portable vehicle-mounted refrigerator is needed to solve the above problems.

[0003] Chinese Patent with Publication No. CN212778169U discloses a portable vehicle-mounted refrigerator, which includes a box body and casters. The casters are installed on the box body. It also includes a handle assembly, which includes a large handle, a small handle and a fixed seat. The large handle is movably connected to the small handle, and the small handle is movably connected to the fixed seat. The fixed seat is fixed on the outer side wall of the box body. There is a handle storage groove on the outer side wall of the box body, and the large handle and the small handle are placed on the handle storage groove; for this vehicle-mounted refrigerator, by setting a large handle and a small handle that are movably connected to each other on the box body and cooperating with the casters, when the box body needs to be moved, the user can pull out the small handle together with the large handle; when the handle assembly is not in use, the user makes full use of the limited groove space and tightly stores the large handle and the small handle on the handle storage groove of the box body. Therefore, this handle structure does not affect the overall volume of the vehicle-mounted refrigerator, so as to reduce the packaging cost and transportation cost of the manufacturer.

[0004] Although it is convenient for people to pull the vehicle-mounted refrigerator through the large handle and the small handle in this patent, the height of the vehicle-mounted refrigerator is relatively low, and people need to bend down when pulling the vehicle-mounted refrigerator, which will cause physical discomfort after long-term movement. Moreover, although the casters in this patent facilitate the movement of the vehicle-mounted refrigerator, when the vehicle-mounted refrigerator is placed in the vehicle and sudden braking or other situations occur, the vehicle-mounted refrigerator will move back and forth in the vehicle, which poses a certain danger. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a portable vehicle-mounted refrigerator, which can effectively improve the comfort when moving the vehicle-mounted refrigerator, and can be locked when the vehicle-mounted refrigerator is placed in the vehicle or placed outdoors, having the advantage of preventing the vehicle-mounted refrigerator from sliding randomly.

[0006] The purpose of the present utility model is to provide a portable vehicle-mounted refrigerator, which includes a vehicle-mounted refrigerator body. A cover body is hinged to the top of the vehicle-mounted refrigerator body. A storage cavity is formed inside the vehicle-mounted refrigerator body. Cup holder assemblies are rotatably arranged on both sides inside the storage cavity. Grooves are formed at the four corners of the bottom of the vehicle-mounted refrigerator body, and rollers are rotatably arranged in the grooves. A rotating shaft groove is formed at a position near the bottom of the vehicle-mounted refrigerator body, and the rotating shaft groove communicates with the two grooves on the same side. A locking assembly for locking the rollers is rotatably arranged in the rotating shaft groove. A storage groove is formed at the front end of the vehicle-mounted refrigerator body, and a telescopic handle assembly is rotatably arranged in the storage groove.

[0007] Further, the telescopic handle assembly includes a mounting block, which is rotatably arranged at a position near the bottom inside the storage groove. Two telescopic rods are fixedly arranged at both ends of the top of the mounting block, and a handle is fixedly arranged at the top of the telescopic rods.

[0008] Further, the locking assembly includes a round shaft and a through hole. The through hole is formed in the groove on one side of the vehicle-mounted refrigerator body. The round shaft is rotatably arranged in the rotating shaft groove, and one end of the round shaft passes through the through hole and is fixedly connected with a torsion block. Two eccentric blocks are fixedly arranged on the round shaft, and both eccentric blocks are fixedly arranged above the rollers. A first pin hole and a second pin hole are respectively formed on one side of the through hole, and a pin plate that can slide and cooperate with the first pin hole and the second pin hole is fixedly arranged inside the torsion block.

[0009] Further, the cup holder assembly includes a cross plate and a limiting plate. One end of the cross plate is rotatably arranged on one side inside the storage cavity, a limiting block is fixedly arranged on the inner wall of the storage cavity at the bottom of the cross plate, and two water cup placement openings are formed on the cross plate.

[0010] Further, a clamping shaft is fixedly arranged at the bottom of the handle, and a clamping groove is fixedly arranged on the groove wall of the storage groove. The clamping shaft is movably clamped in the clamping groove.

[0011] Further, an anti-slip pad is fixedly arranged on the outer surface of the roller.

[0013] The working principle and usage principle of the present utility model are as follows: The device is facilitated to move through rollers. By pulling the torsion block at one end of the round shaft outwards, at the same time, the pin plate slides out from the first pin hole, and then the round shaft is rotated to align the pin plate with the second pin hole and insert it. At this time, both eccentric blocks are in close contact with the surface of the roller. The friction generated when the eccentric wheel is in contact with the roller locks the roller after the device moves to a suitable position. In the telescopic handle assembly, first, the clamping shaft is pulled out from the clamping groove, and then the telescopic rod is unfolded upwards to increase the length of the telescopic rod. By holding the handle and pulling the device forward, and cooperating with the rollers, people can pull the car refrigerator in an upright position. When it is necessary to place water that is prone to tipping into the car refrigerator, the horizontal plate is rotated downwards, and the horizontal plate can be horizontally placed in the storage cavity of the car refrigerator through the limit block. Then, the water cup is passed through the water cup placement opening so that the bottom of the water cup contacts the bottom of the storage cavity of the car refrigerator, and the water cup is limited by the horizontal plate and the water cup placement opening.

[0014] Compared with the prior art, the beneficial effects of the present utility model are:

[0015] 1. Compared with the prior art, the present utility model can pull the device without bending down when it is necessary to pull the device through the rotatable telescopic handle assembly, and when the car refrigerator body is placed in the vehicle, it is stored in the storage groove, effectively avoiding the telescopic handle assembly occupying too much space in the vehicle.

[0016] 2. Compared with the prior art, the present utility model not only facilitates the movement of the device through the combination of rollers and the locking assembly, but also locks the rollers of the device when the device moves to a suitable position or is placed in the vehicle, avoiding accidental sliding of the car refrigerator body due to vehicle jolts or uneven ground.

[0017] 3. Compared with the prior art, the present utility model not only limits the water cup placed in the device through the cup holder assembly, preventing the water cup in the car refrigerator from shaking left and right when the vehicle shakes, but also rotates it upwards for storage when the water cup is not needed, avoiding occupying the storage space inside the car refrigerator body.
