With the continuous increase of the refrigerator volume, the size of the bottle frame is getting larger and larger, and the difficulty and requirements for fixing the bottle frame are getting higher and higher. During the logistics transportation process, in order to prevent damage to the bottle frame itself and other components caused by the movement of the bottle frame, objectively, it is necessary to assemble the bottle frame and the door body more tightly. However, if the bottle frame is installed too tightly, it will cause inconvenience for users to disassemble and assemble. Therefore, there is an urgent need for a fixing structure for the bottle frame that can firmly fix the bottle frame in the unused state, and is not too tight when the bottle frame is taken, facilitating users to disassemble and assemble the bottle frame. Based on this, the present invention is proposed. Summary of the Invention

[0026] Referring to Figures 1 to 5As shown, according to an embodiment of the present invention, a refrigerator door is provided, which includes a door body 1 and a bottle frame 2. Among them, there are oppositely arranged clamping protrusions 11 on the inner side wall of the door body 1, and clamping grooves 21 are provided on the opposite two sides of the bottle frame 2. Refer to Figure 1 the orientation shown. Specifically, there are at least two clamping protrusions 11. At least two clamping protrusions 11 are arranged oppositely at intervals left and right. Correspondingly, two clamping grooves 21 are also correspondingly constructed on the left and right side walls of the bottle frame 2. The bottle frame 2 forms a clamping connection through the cooperation of the clamping grooves 21 and the clamping protrusions 11. There is an assembly gap between the clamping protrusions 11 and the clamping grooves 21, and this assembly gap is also the gap between the clamping protrusions 11 and the clamping grooves 21. The refrigerator door further includes a telescopic device 3 connected to the door body 1. The telescopic device 3 is correspondingly arranged with a clamping protrusion 11. The telescopic device 3 includes a first force-applying member 31 and a driving member 32. The first force-applying member 31 has a clamping state in which it is located in the assembly gap and contacts the first side groove vertical wall of the clamping groove 21, and the first force-applying member 31 also has a gap state in which it is separated from the first side groove vertical wall of the clamping groove 21. The driving member 32 can drive the first force-applying member 31 to switch between the clamping state and the gap state. In this technical solution, the first force-applying member 31 can be controlled to switch between the clamping state and the gap state. In this way, when the user needs to disassemble or assemble the bottle frame 2, the driving member 32 can be used to drive the first force-applying member 31 to be in the gap state, so as to facilitate the user to take out or assemble the bottle frame 2. When the user does not operate the bottle frame 2, the first force-applying member 31 is controlled to be in the clamping state to ensure that the bottle frame 2 is clamped on the door body 1, and prevent potential damage caused by the loose connection between the bottle frame 2 and the door body 1 resulting in the movement of the bottle frame 2.

[0027] In a preferred embodiment, the telescopic device 3 further includes a second force-applying member 33. The second force-applying member 33 has a clamping state in which it is located in the assembly gap and contacts the second side groove vertical wall of the clamping groove 21, and the second force-applying member 33 also has a gap state in which it is separated from the second side groove vertical wall of the clamping groove 21. The first side groove vertical wall and the second side groove vertical wall are arranged parallel and oppositely. The driving member 32 can also drive the second force-applying member 33 to switch between the clamping state and the gap state. Through the first force-applying member 31 and the second force-applying member 33, they can simultaneously act on the opposite two side groove vertical walls of the clamping groove 21 of the bottle frame 2, and can ensure the stable and reliable clamping state of the bottle frame 2.

[0028] The driving component 32 can be, for example, a driving structure such as a steering gear. In one embodiment, the driving component 32 can specifically adopt a rotary motor. The output end of the rotating shaft of the rotary motor has a gear 321. The first force applying member 31 has a first rack portion 311, and the second force applying member 33 has a second rack portion 331. The first rack portion 311 meshes with the gear 321, and the second rack portion 331 meshes with the gear 321. The first rack portion 311 and the second rack portion 331 are arranged in parallel and opposite to each other. Since the first rack portion 311 and the second rack portion 331 are respectively on opposite sides of the gear 321 and are arranged in parallel, when the gear 321 rotates in one direction, the moving directions of the first rack portion 311 and the second rack portion 331 will be opposite under the action of the meshing teeth. For example, Figure 4 As shown, when the rotary motor rotates forward, the first rack portion 311 and the second rack portion 331 move away from each other, so that the two force applying members can apply force to the bottle frame 2 at the same time to achieve the purpose of clamping the bottle frame 2. On the contrary, when the rotary motor rotates in the reverse direction, the first rack portion 311 and the second rack portion 331 move towards each other, so that the two force applying members are separated from contact with the bottle frame 2 and the clamping of the bottle frame 2 is released. By switching the rotation direction of a single rotary motor, the clamping or release of the bottle frame 2 can be achieved. The structure and control are simple, and the structure is compact.

[0029] In a specific embodiment, the first force applying member 31 further includes a first force applying plate 312. The first force applying member 31 contacts the first side groove vertical wall through the first force applying plate 312. The second force applying member 33 further includes a second force applying plate 332. The second force applying member 33 contacts the second side groove vertical wall through the second force applying plate 332. The first force applying plate 312 and the second force applying plate 332 are arranged in parallel and at intervals. Specifically, the first force applying plate 312 and the second force applying plate 332 are respectively perpendicular to the moving directions of the first rack portion 311 and the second rack portion 331, and an elastic member 34 (specifically, a spring for example) is connected between the two. By arranging the elastic member 34 between the two force applying plates, the overall structure of the telescopic device 3 can operate more stably. Based on this structure, in a preferred embodiment, the telescopic device 3 further includes a force measuring sensor. The force measuring sensor can detect the tension or pressure borne by the elastic member 34. By detecting the tension or pressure borne by the elastic member 34, it can be judged whether the displacements of the first force applying member 31 and the second force applying member 33 reach the preset values, and then whether the driving component 32 continues to operate can be controlled to prevent damage caused by excessive clamping force on the bottle frame 2. It should be noted that in the present invention, by arranging the force measuring sensor to detect the tension or pressure of the elastic member 34, there is no need to arrange a tension sensor and a pressure sensor at the corresponding positions inside or outside the telescopic device 3, reducing the application of sensors and lowering the manufacturing cost.

[0030] In some embodiments, the inner side of the door body 1 has a receiving cavity, the telescopic device 3 is located in the receiving cavity, a clamping protrusion 11 is disposed opposite to the first protrusion vertical wall opposite to the first side groove vertical wall of the card slot 21 and the second protrusion vertical wall opposite to the second side groove vertical wall. A first through hole for the first force-applying plate 312 to enter and exit is formed on the first protrusion vertical wall, and a second through hole for the second force-applying plate 332 to enter and exit is formed on the second protrusion vertical wall. In this technical solution, the telescopic device 3 is arranged inside the door body 1, and only the first force-applying plate 312 and the second force-applying plate 332 are selectively controlled to enter the corresponding fitting gaps. While the structure is more compact, the refrigerator door also has a more aesthetic appearance.

[0031] In some embodiments, a human body sensing device is further provided on the inner side wall of the door body 1, such as an infrared sensor, a proximity switch, etc., which can detect whether there is someone near the door body 1 when the door body 1 is opened, and thus can more accurately control the operation of the telescopic device.

[0032] According to an embodiment of the present invention, a refrigerator is further provided, including the above-mentioned refrigerator door.

[0033] According to an embodiment of the present invention, a refrigerator control method is further provided for controlling the above-mentioned refrigerator, including the following steps:

[0034] Judge the opening and closing state of the refrigerator door and whether there is someone near the refrigerator door. Specifically, the human body sensing device is arranged on the inner side wall of the door body. When the refrigerator door is opened, it will face the outside of the refrigerator, and then detect whether there is someone near the door body 1. At this time, it can be understood that when the human body sensing device detects that there is someone nearby, it also means that the refrigerator door is in the open state;

[0035] When the refrigerator door is in the open state and it is detected that there is someone near the refrigerator door, it indicates that the user is very likely to need to operate the bottle frame 2. Therefore, at this time, control the driving component 32 to operate so that the first force-applying member 31 and the second force-applying member 33 are both in the gap state, so as to facilitate the user to disassemble and assemble the bottle frame 2 at any time. At this time, the corresponding elastic member 34 is in a compressed state; otherwise, that is, although the refrigerator door is in the open state, the user is not near the door body 1 temporarily or the refrigerator door is in the closed state. At this time, control the driving component 32 to operate so that the first force-applying member 31 and the second force-applying member 33 are both in the clamping state. At this time, the corresponding elastic member 34 is in a stretched state. Specifically, when the driving component 32 is a rotary motor, when the refrigerator door is in the open state and it is detected that there is someone near the refrigerator door, control the rotary motor to rotate in the first rotation direction; otherwise, control the rotary motor to rotate in the second rotation direction.

[0036] In some embodiments, when the telescopic device 3 includes an elastic member 34, when the tensile force borne by the elastic member 34 reaches a preset tensile value (detected by a force sensor), the rotation motor is controlled to stop, preventing excessive displacement of the two force-applying plates from damaging the bottle frame 2; or, when the pressure borne by the elastic member 34 reaches a preset pressure value (detected by a force sensor), the rotation motor is controlled to stop.

[0037] Those skilled in the art can easily understand that, on the premise of no conflict, the advantageous technical features of the above various embodiments can be freely combined and superimposed.

[0038] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention. The above is only the preferred implementation manner of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and modifications can still be made, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
