Description

Technical Field

[0001] The utility model relates to the technical field of vehicle-mounted refrigerator equipment, in particular to a slow-bounce, easy-opening vehicle-mounted refrigerator door. Background Art

[0002] With the improvement of people's living standards and the increase in travel needs, the use of car refrigerators in cars is becoming more and more common. Currently, there are two main ways to open the door of car refrigerators on the market:

[0003] One method is to press the switch and then manually pry the door open. However, this method has obvious drawbacks. When the user's hands are sweaty, they tend to slip, making it difficult to open the door. This is inconvenient in practice, especially when urgently needing to retrieve something from the refrigerator, as the door may not be opened smoothly, causing delays.

[0004] The other method is to have the door automatically pop open after pressing the switch. While this method offers a certain degree of convenience, it also presents several issues. First, closing the door requires overcoming the force that pushes it open, resulting in a high closing force and an unpleasant feel. Second, when the door is heavy, a significant spring force is required to automatically open the door, which increases the closing force even further. This not only increases the difficulty of closing the door but can also cause damage to the door and the refrigerator structure.

[0005] In summary, the existing door opening method of the car refrigerator has many shortcomings and cannot meet the user's demand for convenient and comfortable use experience. Therefore, it is necessary to improve and innovate the door structure and door opening method of the car refrigerator. Utility Model Content

[0006] The purpose of the utility model is to provide a slow-bounce and easy-open vehicle refrigerator door to solve the problems raised in the background technology.

[0007] To achieve the above-mentioned purpose, the utility model provides the following technical solution, which includes a box frame, a pair of arc-shaped mounting shells are symmetrically provided on both sides of the rear top of the box frame, a door inner shell is movably provided on the two arc-shaped mounting shells, a convex shell is provided at the position of the top of the door inner shell corresponding to the two arc-shaped mounting shells, the arc-shaped mounting shells are located in the convex shells, a pair of mounting frames are symmetrically provided between the two convex shells, a clamping plate is provided on the side of one of the mounting frames, a damper is provided in the mounting frame, the movable end of the damper passes through the convex shell and is provided in the arc-shaped mounting shell, a torsion spring is provided on the outer side of one of the dampers, one end of the torsion spring is clamped on the mounting frame, and the other end thereof is clamped on the clamping plate.

[0008] As a preferred embodiment of the present invention, a button is provided at the front end of the inner shell of the door body.

[0009] As a preferred embodiment of the present invention, a snap groove is provided at a position corresponding to the button on the top of the box frame, and a snap plate is provided at the bottom of the snap groove.

[0010] As a preferred embodiment of the present invention, the mounting bracket is arranged on the inner shell of the door body by means of a plurality of screws.

[0011] Compared with the prior art, the above technical solution of the present invention has the following beneficial technical effects:

[0012] 1. When the refrigerator door needs to be opened, the passenger only needs to manually press the button. After the button buckle is pushed out from the buckle plate, the inner shell of the door body bounces upward under the torsion of the torsion spring. This design avoids the problem of difficulty in opening the door due to sweaty hands in the traditional manual door-opening method. Even under some unfavorable hand conditions, the door opening action can be started relatively easily.

[0013] 2. In the process of the door body bouncing upward, the two dampers work together to reduce the upward force, so that the door body can be opened slowly. When the left and right angles of the opening between the inner shell of the door body and the box frame reach a balanced state, the torsion spring torsion has not been completely released. At this time, the remaining torsion spring torsion is equal to the door gravity minus the friction force on the two dampers, which means that the subsequent manual prying of the cover door only requires light force to make the door rotate and open. The user can easily control the force and speed of opening the door according to their needs, which improves the convenience and comfort of use.

[0014] 3. Compared with the traditional automatic pop-up door opening method, the present invention does not need to overcome excessive force to open the door when closing the door, because the torsion of the torsion spring is reasonably controlled and released during the door opening process, and will not make the closing force too large like the traditional automatic pop-up door opening method, thereby improving the feel of closing the door. At the same time, it also reduces the damage to the door body and refrigerator structure caused by excessive closing force, thereby extending the service life of the car refrigerator.

[0022] To make the objectives, technical solutions, and advantages of the present invention more clearly understood, the present invention is further described below in conjunction with specific embodiments and with reference to the accompanying drawings. It should be understood that these descriptions are merely illustrative and are not intended to limit the scope of the present invention. Furthermore, descriptions of known structures and technologies are omitted in the following description to avoid unnecessary confusion regarding the concepts of the present invention.

[0023] like Figures 1-6 As shown, the present invention proposes a slow-bounce and easy-open car refrigerator door. The device involved in the present invention includes a box frame 1, a pair of arc-shaped mounting shells 10 are symmetrically arranged on both sides of the rear top of the box frame 1, and a convex shell 25 is provided at the position corresponding to the two arc-shaped mounting shells 10 on the top of the door inner shell 2. The arc-shaped mounting shells 10 are just located in the convex shells 25 to achieve a movable connection between the two. A pair of mounting brackets 21 are symmetrically arranged between the two convex shells 25. The mounting brackets 21 are firmly set on the door inner shell 2 by several screws 24. A clamping plate 22 is provided on the side of one of the mounting brackets 21. A damper 3 is installed in the mounting frame 21. The movable end of the damper 3 passes through the convex shell 25 and is arranged in the arc-shaped mounting shell 10 to play a buffering role. A torsion spring 23 is sleeved on the outside of one of the dampers 3. One end of the torsion spring 23 is clamped on the mounting frame 21, and the other end is clamped on the clamping plate 22 to provide torque for the door inner shell 2 to pop open. In addition, a button 20 is provided at the front end of the door inner shell 2, and a snap groove 11 is opened at the top of the box frame 1 corresponding to the position of the button 20. A snap plate 12 is provided at the bottom of the snap groove 11. The door is closed and locked by the cooperation of the button 20 and the snap plate 12.

[0024] When it is necessary to open the cover door of the car refrigerator, the passenger first needs to manually press the button 20 so that the buckle of the button 20 is pushed out from the buckle plate 12. Then, under the torsional force of the torsion spring 23, the inner shell 2 of the door body will bounce upward. At the same time, the two dampers 3 cooperate with each other to reduce the upward force, so that the door body can be opened slowly. In this process, the inner shell 2 of the door body and the box frame 1 will gradually open to form an angle of about 10 degrees. When the equilibrium state is reached, the torsional force of the torsion spring 23 has not been completely released. At this time, the remaining torsion force of the torsion spring 23 is equal to the gravity of the door minus the friction force on the two dampers 3. Continue to open the door and pry it open with your hands. At this time, you only need to apply light force to make the door rotate open. This design not only ensures the smooth opening of the door, but also avoids accidents caused by excessive opening force.

[0025] It should be understood that the above-described specific embodiments of the present invention are merely illustrative of or explanation of the principles of the present invention and do not constitute limitations of the present invention. Therefore, any modifications, equivalent substitutions, improvements, etc. made without departing from the spirit and scope of the present invention shall be included within the scope of protection of the present invention. In addition, the appended claims of the present invention are intended to cover all changes and modifications that fall within the scope and metes and bounds of the appended claims, or equivalents of such scope and metes and bounds.
