Description

Technical Field

[0001] This utility model relates to the field of vehicle refrigerator technology, specifically a hinged door structure for a flip-top vehicle refrigerator. Background Technology

[0002] With the continuous improvement of automotive lifestyles, car refrigerators have become an indispensable item for car owners during daily travels and are now a common accessory in modern automobiles. Car refrigerators typically offer convenient food and beverage storage functions, providing refrigeration services to ensure drivers can enjoy fresh food and drinks during long drives. However, existing conventional flip-top car refrigerator door designs still have certain shortcomings.

[0003] Conventional flip-top car refrigerators require the door to open to a certain angle (generally ≥90°) to fully close or spring open to an angle suitable for retrieving items. While this design is simple and intuitive, different users have different requirements for the opening angle. Some users prefer a smaller opening angle, while others prefer a larger one. This means that existing refrigerator doors cannot be flexibly adjusted to meet user needs, resulting in inconvenience and discomfort during use.

[0004] Furthermore, refrigerator doors lacking springs or damping mechanisms tend to produce loud slamming noises when closed, which not only affects the user experience but may also cause discomfort to the surrounding environment. No solution has yet been proposed to address these technical issues. Utility Model Content

[0005] To address the problems in related technologies, this utility model proposes a hinged door suspension structure for a flip-top car refrigerator to overcome the aforementioned technical issues in existing technologies. The purpose of this utility model is to overcome the weight of the door throughout the entire opening and closing process, enabling it to be suspended at any position. Different users can open the door at any angle to retrieve items according to their needs, resulting in a better user experience.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a hinged door suspension structure for a flip-top vehicle refrigerator, comprising a refrigerator top frame, an inner door panel on one side of the refrigerator top frame, a plurality of hinge seats between the refrigerator top frame and the inner door panel, the two ends of the hinge seats being connected to the refrigerator top frame and the inner door panel respectively, an outer door panel on the side of the inner door panel away from the refrigerator top frame, a plurality of fixing slots on the hinge seats, a mini damper on the hinge seats, a damping pressure plate installed on the inner door panel, a slot on the damping pressure plate, the two ends of the mini damper extending into the fixing slot and the slot respectively, a rotating shaft on the damping pressure plate, one end of the rotating shaft passing through the damping pressure plate, the mini damper and the hinge seats in sequence, extending into the interior of the inner door panel, and the end being connected to the inner door panel.

[0007] Preferably, the mini damper includes a fixed end and a rotating end, the fixed end being disposed inside the fixed groove and fixedly connected to the fixed groove, and the rotating end being disposed inside the slot.

[0008] Preferably, a handle is provided on the outer panel of the cabinet door.

[0009] Preferably, there are two of each of the mini damper, fixing groove, card slot, hinge seat, and damping pressure plate.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0020] Example

[0021] Please see Figure 1-5 This utility model proposes a technical solution for a hinged door suspension structure for a flip-top vehicle refrigerator: A flip-top vehicle refrigerator door suspension structure includes a refrigerator upper frame 1, an inner door panel 2 on one side of the upper frame 1, and several hinge seats 3 between the upper frame 1 and the inner door panel 2. The two ends of the hinge seats 3 are connected to the upper frame 1 and the inner door panel 2, respectively. An outer door panel 4 is located on the side of the inner door panel 2 away from the upper frame 1. Several fixing points are provided on the hinge seats 3. A fixed groove and a hinge seat 3 are provided with a mini damper 5. Specifically, the mini damper 5 can rotate 360° under a certain torque. A damping pressure plate 6 is installed on the inner panel 2 of the door. The damping pressure plate 6 has a slot. The two ends of the mini damper 5 extend into the fixed groove and the slot respectively. The damping pressure plate 6 is also provided with a rotating shaft 7. One end of the rotating shaft 7 passes through the damping pressure plate 6, the mini damper 5 and the hinge seat 3 in sequence, and extends into the inner panel 2 of the door, and the end is connected to the inner panel 2 of the door.

[0022] In this embodiment, when the outer door panel 4 is manually opened, causing the inner door panel 2 connected to it to flip open, the outer door panel 4 and the inner door panel 2 overcome the torque of the mini damper 5, causing the rotating end 502 of the mini damper 5 to rotate relative to the fixed end 501 on the hinge seat 3. The external force stops when the rotation reaches any angle. At this time, the weight of the outer door panel 4 and the inner door panel 2 is less than the torque of the damper, so the outer door panel 4 and the inner door panel 2 do not perform a closing rotational movement. At the same time, without the external force, they no longer perform an opening rotational movement, and the outer door panel 4 and the inner door panel 2 achieve a hovering state. The outer door panel 4 and the inner door panel 2 rotate relative to the refrigerator top frame 1 on the refrigerator. The mini damper 5 is used to achieve the hovering function when the car refrigerator door is opened and closed.

[0023] Please see Figure 2-5 As shown, the mini damper 5 further includes a fixed end 501 and a rotating end 502. The fixed end 501 is disposed inside the fixed groove and is fixedly connected to the fixed groove, while the rotating end 502 is disposed inside the slot.

[0024] In this embodiment, the fixed end 501 and the rotating end 502 are coaxially aligned by the rotating shaft 7. The fixed end 501 is fixed to the hinge seat 3, and the rotating end 502 is fixed to the inner panel 2 of the door by the damping pressure plate 6.

[0025] Please see Figure 1 As shown, a handle 8 is further provided on the outer panel 4 of the box door.

[0026] In this embodiment, a handle 8 is provided to facilitate opening the outer panel 4 and the inner panel 2 of the cabinet door.

[0027] Please see Figure 2-3 As shown, furthermore, there are two mini dampers 5, two fixing slots, two card slots, two hinge seats 3 and two damping pressure plates 6.

[0028] Please see Figure 2-4 As shown, the damping pressure plate 6 is further fixedly installed on the inner panel 2 of the door by bolts.

[0029] In this embodiment, bolted connections are used to facilitate installation and disassembly.

[0030] The working principle of this utility model:

[0031] The refrigerator top frame 1 is installed on the refrigerator. Both the outer door panel 4 and the inner door panel 2 are doors. When the outer door panel 4 is manually opened, causing the inner door panel 2 connected to it to flip open, the outer door panel 4 and the inner door panel 2 overcome the torque of the mini damper 5, causing the rotating end 502 of the mini damper 5 to rotate relative to the fixed end 501 on the hinge seat 3. The external force stops when the rotation reaches any angle. At this time, the weight of the outer door panel 4 and the inner door panel 2 is less than the torque of the damper, so the outer door panel 4 and the inner door panel 2 do not perform a closing rotational movement. At the same time, without the external force, they no longer perform an opening rotational movement, and the outer door panel 4 and the inner door panel 2 are suspended. This allows the door to overcome its own weight throughout the opening and closing process, achieving suspension at any position. Different users can open the door at any angle to retrieve items according to their needs, resulting in a better user experience.
