Description

Technical Field

[0001] This utility model relates to the field of refrigeration equipment technology, and in particular to a vehicle refrigerator door slow-opening device based on torsion spring damping linkage. Background Technology

[0002] With the widespread use of automobiles in daily life, car refrigerators have become an essential device for many car owners, providing refrigeration and preservation functions while driving. In actual use, the way the refrigerator door opens directly affects the user experience and safety.

[0003] Currently, conventional refrigerator door opening mechanisms typically lack a cushioning effect, relying primarily on gravity to open. When a user opens the refrigerator door, the door opens rapidly due to gravity. While this opening method meets basic usage needs in ordinary home environments, it exposes numerous problems in a vehicle setting. During driving, road conditions are complex and changeable, with frequent bumps and sudden braking. In this dynamic environment, the rapid opening of a conventional refrigerator door not only easily leads to accidental collisions with the rapidly opening door when retrieving items, causing personal injury, but also may cause items inside the refrigerator to fall or spill out due to the violent shaking of the door, resulting in both item loss and increased difficulty in cleaning the vehicle interior. Furthermore, the rapid opening of the refrigerator door causes a large amount of cold air to escape quickly, reducing the refrigerator's cooling efficiency and increasing energy consumption.

[0004] Therefore, there is an urgent need for a device that can adapt to the in-vehicle environment and enable the refrigerator door to open slowly and stably, so as to improve the user experience and practicality of in-vehicle refrigerators. Utility Model Content

[0005] This invention provides a vehicle refrigerator door soft-opening device based on torsion spring damping linkage, which can solve the problem of no buffer when opening vehicle refrigerator doors in the prior art.

The door body includes a door cover plate and a door base, and the hinge is connected to the bottom of the opening surface of the door body and the bottom of the door base, respectively.

[0007] It also includes a buffer assembly, which includes a torsion spring and a torsion spring baffle. One end of the torsion spring is sleeved on the outer end of the hinge shaft, and the other end of the torsion spring abuts against the vertical part of the torsion spring baffle.

[0008] The buffer assembly also includes a damper mounted on one side of the hinge.

[0009] Furthermore, the door also includes a switch assembly, which is disposed between the door cover and the door base. A retaining ring is provided on the opening surface of the housing, and the switch assembly cooperates with the retaining ring to achieve the closure of the door and the housing.

[0010] Furthermore, the switch assembly includes a button, a button bracket, and a plug plate. The button bracket is fixedly connected to the inside of the housing cover. The button is inserted into the button bracket. The housing cover has a notch corresponding to the button. The plug plate is slidably connected to the housing base. The end of the button abuts against the plug plate. The top two ends of the plug plate are provided with plug blocks. The plug blocks cooperate with the plug ring. When the button is pressed, the plug plate slides downward and the plug blocks disengage from the plug ring.

[0011] Furthermore, a pin is provided at the end of the button, and a slide is provided at the center of the top of the insert plate. The top surface of the slide is inclined, and the pin abuts against the inclined surface of the slide. When the button is pressed, the pin presses against the slide and moves downward.

[0012] Furthermore, a return spring is provided on the pin.

[0013] Furthermore, an installation plate is provided on the inner wall of the door base, and the insertion plate includes multiple rectangular frames. One side of each rectangular frame is inserted into the installation plate, and the insertion plate is slidably connected to the installation plate.

[0014] Furthermore, a second reset spring is also provided inside the door body. One end of the second reset spring is fixedly connected to the mounting plate, and the other end of the reset spring is fixedly connected to the bottom of the insert plate.

[0015] Furthermore, it also includes a buffer pad, which is disposed at the bottom and top of the mounting plate. When the insert plate moves up and down, the buffer pad abuts against the top and bottom surfaces of the inner wall of the rectangular frame.

[0016] Furthermore, the door also includes a rotating bracket, which is an arc-shaped panel. Limiting holes are provided on both sides of the opening surface of the box. One end of the rotating bracket is fixedly connected to the door, and the other end of the rotating bracket passes through the limiting hole.

[0018] The beneficial effects of this utility model are:

[0019] This utility model provides a vehicle refrigerator door slow-opening device based on torsion spring damping linkage, including a buffer assembly. The buffer assembly includes a torsion spring and a damper. Through the linkage between the two, in the initial stage of door opening, the elastic force of the torsion spring assists the door to open, reducing the difficulty of opening. When the door is opened to a certain angle, the elastic force of the torsion spring is transformed into resistance, which works together with the stabilizing damping force generated by the damper to significantly slow down the opening speed of the door, making the door open slowly and smoothly. This greatly reduces the risk of accidental collision between the door and the user, and effectively reduces the shaking amplitude during the door opening process, so that the items inside the refrigerator can remain relatively stable, avoiding damage to items caused by the door opening, reducing the difficulty of cleaning the vehicle interior, and making it safer and more convenient for users to take out and put in items.

[0020] In addition, the device of this utility model reduces the amount of cold air lost during the door opening process through the slow-opening function, improves the refrigeration efficiency of the refrigerator, effectively reduces the energy consumption of the vehicle refrigerator, saves energy and protects the environment, and enhances the practicality and economy of the vehicle refrigerator.

[0030] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0031] like Figures 1 to 7 As shown in the figure, the present invention provides a vehicle refrigerator door soft-opening device based on torsion spring damping linkage, including a door body 1 and a cabinet body 2. The door body 1 and the cabinet body 2 are rotatably connected by a hinge 3. The door body 1 includes a door cover plate 11 and a door base 12. The hinge 3 is connected to the bottom of the opening surface of the door body 1 and the bottom of the door base 12 respectively, so that the door body 1 can rotate relative to the cabinet body 2.

[0032] Specifically, such as Figures 1-3 As shown, the door body 1 also includes a rotating bracket 14, which is an arc-shaped panel. Limiting holes 23 are provided on both sides of the opening surface of the housing 2. One end of the rotating bracket 14 is fixedly connected to the door body 1, and the other end of the rotating bracket 14 passes through the limiting hole 23 to guide and limit the rotation of the door body 1. Stops 22 are provided on both sides of the housing 2. A protruding structure is provided at the end of the rotating bracket 14 away from the door body 1. When the door body 1 rotates to the maximum limit, the protruding structure abuts against the stop 22 to prevent the door body 1 from rotating excessively.

[0033] like Figure 3 and Figure 4As shown, a buffer assembly 15 is also provided inside the door body 1. The buffer assembly 15 includes a torsion spring 151, a torsion spring baffle 152 and a damper 153. One end of the torsion spring 151 is sleeved on the outer end of the hinge 3 pivot, and the other end of the torsion spring 151 abuts against the vertical part of the torsion spring baffle 152. The torsion spring baffle 152 is fixedly connected to the rotating bracket 14, and the damper 153 is installed on one side of the hinge 3. In the initial stage of door 1 opening, torsion spring 151 is in a deformed state, generating an outward elastic force to assist door 1 in opening. When door 1 opens to an angle of about 15 degrees, the direction of the elastic force of torsion spring 151 changes, transforming into resistance. It works together with damper 153 to slow down the opening speed of door 1, preventing door 1 from opening too quickly and hitting other objects or generating excessive noise. Torsion spring baffle 152 is fixedly connected to rotating bracket 14, and its vertical part abuts against the other end of torsion spring 151, which serves to fix the position of torsion spring 151 and ensure that torsion spring 151 can stably cooperate with hinge 3 pivot during operation. When door 1 opens downward, damper 153 generates a stable damping force, effectively hindering the rotation speed of door 1, and works in conjunction with torsion spring 151 to achieve smooth and slow opening of door 1.

[0034] like Figure 1 and Figure 3 As shown, the door body 1 also includes a switch assembly 13, which is disposed between the door cover plate 11 and the door base 12. A ring 21 is provided on the opening surface of the housing 2. The switch assembly 13 and the ring 21 cooperate to achieve the closing of the door body 1 and the housing 2.

[0035] Specifically, such as Figure 3 , Figures 5-7 As shown, the switch assembly 13 includes a button 131, a button bracket 132, and a plug plate 133. The button bracket 132 is fixedly connected to the inside of the cover plate of the housing 2. The button 131 is inserted into the button bracket 132, and a notch corresponding to the button 131 is left on the cover plate of the housing 2 for easy user operation. The plug plate 133 is slidably connected to the base of the housing 2. The end of the button 131 abuts against the plug plate 133. A plate 16 is installed on the inner wall of the base 12. The plug plate 133 includes multiple rectangular frames. One side of the outermost rectangular frame is inserted into the mounting plate 16 to achieve a sliding connection between the plug plate 133 and the mounting plate 16. The top two ends of the plug plate 133 are provided with plug blocks 1331. The plug blocks 1331 cooperate with the plug rings 21 on the housing 2. When the button 131 is pressed, the plug plate 133 slides downward and the plug blocks 1331 disengage from the plug rings 21.

[0036] Specifically, such as Figure 5 and Figure 7As shown, a pin 1311 is provided at the end of the button 131, and a slide 1332 is provided at the top center of the insert plate 133. The top surface of the slide 1332 is inclined, and the pin 1311 abuts against the inclined surface of the slide 1332. When the button 131 is pressed, the pin 1311 presses against the slide 1332 and moves downward. A return spring 134 is installed on the pin 1311 for resetting the button 131. A return spring 17 is installed inside the door body 1. One end of the return spring 17 is fixedly connected to the mounting plate 16, and the other end is fixedly connected to the bottom of the insert plate 133, so that the insert plate 133 can automatically reset when it is not subjected to external force. At the same time, buffer pads 18 are installed at the bottom and top of the mounting plate 16. When the insert plate 133 moves up and down, the buffer pads 18 abut against the top and bottom surfaces of the inner wall of the rectangular frame, which plays a role in buffering and shock absorption, reducing noise and wear when the insert plate 133 moves.

[0037] The working principle of this utility model is as follows.

[0038] When the user needs to open the car refrigerator door, press the button 131 located at the notch in the door cover 11. The button 131 moves downward on the button bracket 132. The pin 1311 at the end of the button 131 presses against the inclined surface of the slide block 1332, causing the insert plate 133 to slide downward. The insert blocks 1331 at both ends of the top of the insert plate 133 disengage from the insert ring 21 on the opening surface of the cabinet 2, and the locking state between the door 1 and the cabinet 2 is released.

[0039] Initially, the torsion spring 151 is in an energy storage state. Its outward elastic force assists the door 1 in opening. Under the action of gravity, the door 1 rotates around the hinge 3 axis. As the rotation angle of the door 1 gradually increases, when it reaches about 15 degrees, the direction of the elastic force of the torsion spring 151 changes, and it begins to provide resistance to prevent the door 1 from continuing to open quickly. At the same time, the damper 153 continues to play its role. The damping force it generates works in conjunction with the resistance of the torsion spring 151 to limit the rotation of the door 1. The two work together to make the door 1 open slowly and smoothly until it rotates to the maximum limit. The protruding structure on the rotating bracket 14 abuts against the blocks 22 on both sides of the housing 2, and the door 1 stops rotating.

[0040] The embodiments of this utility model have been described in detail above, but the content described is only a preferred embodiment of this utility model and should not be considered as limiting the scope of implementation of this utility model. All equivalent changes and improvements made in accordance with the claims of this utility model should still fall within the patent coverage of this utility model.
