[0045] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] The principle and structure of the present invention are described in detail below with reference to the accompanying drawings and embodiments.

[0047] Car refrigerators are a continuation of home refrigerators, using either semiconductor electronic refrigeration technology or a compressor. They are generally quiet and low-pollution. Simply plug the power cord into the cigarette lighter while driving to cool the refrigerator.

[0048] There are two main types of car refrigerators on the market. One is the semiconductor car refrigerator, which relies on electronic chips for cooling. Using a PN junction constructed from specialized semiconductor materials, it forms a thermocouple pair, generating the Peltier effect—a novel refrigeration method using direct current. Its cooling temperature range is 5 to 65°C. The advantages of this type of refrigerator are its ability to both cool and heat, its environmental friendliness, its small size, its low cost, its vibration-free operation, its long lifespan. However, its disadvantages are its low cooling efficiency, its temperature being affected by ambient temperature, its inability to reach sub-zero temperatures, and its small capacity. The other type is the compressor car refrigerator. Compressors are a legacy technology used in traditional refrigerators, with a low cooling temperature of -18°C to 10°C. While they offer high cooling efficiency, can produce ice and preserve freshness, and are large in size, they are the future trend in car refrigerator development. However, these refrigerators are heavy, inconvenient to carry, and relatively expensive. The compressors used in compressor car refrigerators are primarily produced in Germany and Japan.

[0049] The current car refrigerators are characterized by their small size and easy mobility. They are like a smaller version of a freezer and are mostly placed in the trunk of a car. After opening the trunk of an SUV or a hatchback, you can directly open the door of the car refrigerator to take out items. However, for a three-box sedan, due to the limited height of the trunk, it is not very convenient to open the refrigerator door to take out items.

[0050] In view of the above shortcomings, the present invention proposes a box door opening structure, which provides a pop-up component with a button so that the door of the box can automatically pop up, making it convenient for users to open and close.

[0051] Specifically, such as Figures 1 to 4 As shown, the cabinet door opening structure can be specifically applied to a car refrigerator, and includes: a cabinet 1, a cover plate 2, a door body 3 and a pop-up assembly. The top surface of the cabinet 1 is not closed, and a cover plate 2 is installed in the area of ​​the top surface near the left edge. The interior of the cover plate 2 is a hollow structure for installing the pop-up assembly. The door body 3 is hinged to the front edge or the rear edge of the cabinet 1, so that the door body 3 can be rotated upward with its hinged edge as the central axis of rotation to expose the top surface of the cabinet 1, or rotated downward to close the top surface of the cabinet 1. A pop-up assembly is installed on the cover plate 2, and the elastic support member of the pop-up assembly is located on the back of the door body 3. The button 511 of the pop-up assembly causes the door body 3 to be lifted up.

[0052] By setting up a pop-up component, when the user needs to open the refrigerator door, he can directly press the corresponding button to make the door body 3 be lifted up by the elastic support member on the back thereof, which is convenient for further opening of the door body 3 and easy to operate.

[0053] like Figure 3 As shown, in a specific embodiment, when the door body 3 is closed, the edge covers part of the cover plate 2, and a step 21 is provided at the position where the cover plate 2 is covered by the door body 3. The door body 3 is provided with a strip-shaped recess corresponding to the step 21 along the edge, so that the surface of the door body 3 is flush with the surface of the cover plate 2 when the door body 3 is closed.

[0054] By providing the step 21 , the pop-up assembly disposed in the cover plate 2 can push up the door body 3 from the step 21 , which facilitates the arrangement of the components of the pop-up assembly.

[0055] Specifically, the elastic support member of the pop-up assembly is located on the step 21 of the cover plate 2, that is, at the strip-shaped recess on the back of the door body 3. When the elastic support member is compressed downward when the door is closed, the step 21 can provide a certain supporting force.

[0056] like Figure 4 As shown, in a specific embodiment, the door body 3 includes a left door body 31 and a right door body 32. The left door body 31 is arranged on the upper side, and the upper edge is hinged to the box body 1. The right door body 32 is arranged on the lower side, and the lower edge is hinged to the box body 1. One side edge of the cover plate 2 corresponds to the two door bodies 3 at the same time.

[0057] By dividing the door body 3 into two parts, the height occupied by the door body 3 after opening can be reduced. At the same time, the weight of the door body 3 is also smaller, making it more convenient to lift the door body 3 through the pop-up assembly.

[0058] like Figures 5 to 11 As shown, in a specific embodiment, the pop-up assembly includes: a button 511, a door guide column 543 and a gear assembly. A button 511 groove is provided on the surface of the cover 2. The button 511 can move up and down in the installation groove. A button guide column 512 is provided below the button 511. The button guide column 512 is vertically arranged and has a tooth groove on its side for cooperating with the gear. That is, when the button guide column 512 is driven down by the button 511, it can drive the gear cooperating with the button guide column 512 to rotate. The door guide column 543 is vertically arranged in the cavity inside the cover plate 2. Specifically, the inner bottom surface of the cavity is provided with a guide column seat for installing the door guide column 543 (it should be noted that the button guide column 512 can also be provided with a corresponding guide column seat to limit the movement direction of the button guide column 512). A vertical notch is provided on the side of the guide column seat, and the tooth groove on the side of the door guide column 543 is opposite to the vertical notch of the guide column seat, and the door guide column 543 can move up and down in the guide column seat; the gear assembly is installed in the cavity of the cover plate 2, and the gears at both ends of the gear assembly are respectively engaged with the button guide column 512 and the door guide column 543.

[0059] When the button 511 is pressed, the button guide column 512 drives the door guide column 543 to move upward through the gear assembly, driving the connecting rod to move upward synchronously, so that the elastic support member on the connecting rod lifts the door body 3.

[0060] When the door body 3 is closed, the door body guide column 543 is driven to move downward by the elastic support member, and the synchronous driving gear 523 assembly drives the button guide column 512 to move upward, so that the button 511 pops up and resets.

[0061] That is, by means of lifting the door body 3 through the gears in conjunction with the elastic supporting member, the door body 3 can be lifted by directly pressing, making it convenient for the user to further open the door body 3 to store items.

[0062] In a specific embodiment, the gear assembly includes: a button 511 gear, a driving gear 523, a door body 3 gear and a rack 53. The button 511 gear and the driving gear 523 are mounted on a first support seat 521. The first support seat 521 is mounted on the bottom surface of the cavity of the cover plate 2 and is arranged close to the button guide column 512. The button 511 gear and the driving gear 523 can rotate around the axis; wherein the button 511 gear is meshed with the gear guide column, and the button 511 gear is meshed with the driving gear 523. By pressing the button 511, the button guide column 512 is driven to move, and the button guide column 512 synchronously drives the button 511 gear to rotate counterclockwise, and the button 511 gear then synchronously drives the driving gear 523 to rotate clockwise; the door body 3 gear is mounted on a second support seat 541. The second support seat 541 is mounted on the bottom surface of the cavity of the cover plate 2 and is arranged close to the door body guide column 543, and the door body 3 gear is meshed with the door body guide column 543. The rack 53 is located in the cavity of the cover plate 2 and is installed on the rack 53 seat. It can slide horizontally on the rack 53 seat and simultaneously engage with the driving gear 523 and the door body 3 gear.

[0063] That is, the rotation of the gear is converted into up and down vertical motion through the rack 53 and the guide column with the tooth groove, so that the button 511 can drive the door body 3 to open, and the opening method is simple and reliable.

[0064] In this embodiment, the pop-up assembly further includes: a third support base 551 and a slide rod 552. The third support base 551 is mounted on the bottom surface of the cavity inside the cover plate 2, near the center of the rack 53. A sleeve 553 with a slide groove is provided on the top of the third support base 551. One end of the slide rod 552 is vertically bent and snaps into the arc-shaped groove on the side of the drive gear 523. The other end of the slide rod 552 is vertically bent and extends toward the side of the door body 3 to form a latch.

[0065] When the driving gear 523 is driven by the gear of the button 511 to rotate clockwise, its arc-shaped groove rotates synchronously to push the slide bar 552 along the slide groove in the direction away from the door body 3, so that the pin of the slide bar 552 disengages from the pin seat 33 on the side of the door body 3.

[0066] When the driving gear 523 is driven by the rack 53 to rotate counterclockwise, its arc-shaped groove rotates synchronously to push the slide rod 552 along the slide groove toward the direction facing the door body 3, so that the pin of the slide rod 552 is inserted into the pin seat 33 from the side of the door body 3, limiting the door body 3 so that the door body 3 cannot directly pop up and open.

[0067] That is, by providing a latch, the latch can lock the door 3 in a closed state. That is, when used in a car refrigerator, even if the refrigerator shakes during driving, the door of the car refrigerator will not open or close due to the shaking, causing cold air to leak. At the same time, when the door 3 is pressed down, the elastic force generated by the downward pressure of the elastic support member acts on the door guide post 543, causing the door guide post 543 to move downward. The gear assembly then drives the latch to insert into the latch seat 33 on the door 3, thereby preventing the elastic support member from bouncing the door 3.

[0068] In a specific embodiment, a spring 513 providing a rebound force is sleeved on the bottom of the button guide 512. The bottom of the spring 513 is supported on the bottom surface of the cavity of the cover plate 2. The rebound force of the spring 513 makes it easier for the button 511 to rebound and rise, and makes pressing smoother.

[0069] In the embodiment where the door body 3 is divided into two left and right door bodies 3, the button 511 is set in the middle of the cover plate 2, and gear assemblies corresponding to the left door body 31 and the right door body 32 are respectively set on both sides of the button guide column 512.

[0070] That is, by pressing the button 511, the limit of the left door body 31 and the right door body 32 can be simultaneously cancelled, so that the elastic support member can lift the door body 3, that is, one button 511 corresponds to two door bodies 3, reducing the number of parts and improving user convenience.

[0071] In a specific embodiment, the elastic support member is a spring column 554. The spring column 554 is conveniently arranged to be vertical, and the force of the spring column 554 is more easily transmitted to the door body guide column 543, that is, the door body 3 can be stably lifted by the form of the spring column 554.

[0072] In a specific embodiment, the present invention further provides a vehicle-mounted refrigerator, comprising a cabinet, a door, and the above-mentioned door opening structure.

[0073] By setting the car refrigerator to a top-opening structure with left and right double doors, the left and right doors are of the same size, reducing the height occupied by the doors when opened; and the left and right doors of the car refrigerator can be opened with one button, making operation convenient.
