[0002] Existing self-opening refrigerators generally achieve the automatic door-opening function by arranging fixed tracks on the two inner side walls of the refrigerator body and arranging sliding tracks at the corresponding positions of the door. However, in the actual production process of the refrigerator, problems such as door assembly errors or uneven foaming density often occur, resulting in the center of gravity of the door not being on the horizontal line of the support plane formed by the two tracks, that is, the center of gravity of the door is shifted, and the door tilts up and down in the height direction of the refrigerator, affecting the user experience. Summary of the Invention

[0006] A refrigerator body, having a chamber with an opening, and along the height direction of the refrigerator body, the chamber has two inner walls, and the two inner walls are oppositely arranged and are respectively configured as a first inner wall and a second inner wall;
[0007] A door, used to open / close the opening;
[0008] A bracket track unit, including a bracket track, a bracket and a driving member, two bracket tracks are provided, one of the bracket tracks is installed on the first inner wall, the other bracket track is installed on the second inner wall, and the two bracket tracks are symmetrically arranged with the depth direction of the refrigerator body as the axis, the bracket is arranged along the height direction of the refrigerator body and is installed on the door, and each bracket track is respectively connected to both ends of the bracket, the driving member is installed on the bracket track and can drive the bracket track to move, so as to drive the door to move relative to the refrigerator body to open / close the opening.
[0009] It can be understood that in the present application, by symmetrically arranging two support rails with the depth direction of the box body as the axis and connecting them to the support installed on the box door, the two support rails can have a supporting force on the box door at the axis through the support, and this supporting force coincides with the center of gravity of the box door. Such a setting method can ensure that the box door can be supported at the position of its center of gravity, thereby avoiding the inclination of the box door in the length direction of the refrigerator relative to the axis, which affects the user experience; and a driving member is installed on the support rail to be able to drive the support rail by the driving member and drive the box door to move relative to the box body. Under the condition of avoiding the deviation of the center of gravity of the box door, the self-opening function of the refrigerator is realized, improving the user experience.
[0010] In one embodiment, each of the support rails includes a fixed guide rail and a movable guide rail. The fixed guide rail is installed on the corresponding inner wall and has a guide groove. One end of the movable guide rail extends into the guide groove and is slidably connected to the guide groove, and the other end is connected to the box door;
[0011] Wherein, the driving member is installed on the fixed guide rail and is in transmission connection with the movable guide rail.
[0012] It can be understood that the provided guide groove has a guiding effect on the movable guide rail, enabling the movable guide rail to stably drive the box door to move along the direction of the guide groove without shaking or movement deviation, thereby avoiding the phenomenon of the box door tilting or the center of gravity deviating during the movement process.
[0013] In one embodiment, along the depth direction of the box body, a driving groove is provided on the movable guide rail, and driving teeth are provided on the wall surface of the driving groove. A driving wheel is installed on the driving member, and the driving wheel meshes with the driving teeth.
[0014] It can be understood that through the setting of the driving teeth and the driving wheel, the movable guide rail can drive the box door to move relative to the box body by the cooperation of the two, realizing the self-opening of the refrigerator; and the gear transmission of the box door can more precisely control the transmission ratio compared with the push rod structure, thereby accurately controlling the opening or closing action of the box door, further avoiding the deviation of the box door during the movement process, which affects the user experience, and the gear has higher wear resistance and fatigue resistance and can be used repeatedly for a long time, thereby increasing the service life of the self-opening refrigerator.
[0015] In one embodiment, the support rail unit further includes balls. Along the height direction of the box body, the movable guide rail has a first surface and a second surface, and the balls are provided between the first surface and the wall surface of the guide groove, and between the second surface and the wall surface of the guide groove.
[0016] It can be understood that the setting of the balls can increase the smoothness of the movement of the movable guide rail and also enable precise cooperation between the movable guide rail and the fixed guide rail.
[0017] In one embodiment, along the length direction of the box body, a flange is provided on the side surface of the moving guide rail, and one end of the flange away from the moving guide rail abuts against the wall surface of the guide groove in the length direction of the box body.
[0018] It can be understood that the setting of the flange can reduce the contact area between the end surface of the moving guide rail and the wall surface of the guide groove, thereby reducing the frictional resistance of the fixed guide rail to the moving guide rail during the movement of the moving guide rail, further improving the stability of the movement of the box door, and avoiding tilting during its movement.
[0019] In one embodiment, an arc surface is provided at one end of the flange away from the moving guide rail.
[0020] In one embodiment, the support rail unit further includes a vision sensor and a grille. The vision sensor is installed on the fixed guide rail and is signal-connected to the driving member. The grille is provided on the moving guide rail. The grille is configured into N groups, and the N groups of grilles are equidistantly arranged along the length direction of the moving guide rail. Each group of grilles includes M windows. Along the depth direction of the box body from the box door to the box body direction, the number of windows in the N groups of grilles gradually increases or decreases.
[0021] Wherein, N and M are positive integers, and N≥2, M≥1.
[0022] It can be understood that the vision sensor can identify the number of windows or non-windows of the grille, and cooperate with the setting that the number of windows of the N groups of grilles gradually increases or decreases, so as to realize the accurate positioning of the fixed guide rail by the vision sensor, and through the signal connection between the vision sensor and the driving member, the vision sensor can feedback the positioning signal to the driving member, so as to accurately control the speed of opening or closing the box door and the position of the box door relative to the box body.
[0023] In one embodiment, the support is provided with lapping flanges at both ends in the height direction of the box body, and the lapping flanges are lap-connected with the corresponding ends of the moving guide rail.
[0024] In one embodiment, along the height direction of the box body, the first inner wall is located above the second inner wall;
[0025] An inner lining reinforcement is provided inside the box body at the position corresponding to the first inner wall.
[0026] It can be understood that the provided inner lining reinforcement can strengthen the structural strength of the self-opening refrigerator, and can cooperate with the support rail to enable the support rail to be stably installed on the box body.
[0027] The present application also provides the following technical solutions:
[0028] A refrigerator self-opening method, which is implemented based on the self-opening refrigerator in any of the above embodiments. The method includes the following steps:
[0029] Based on the movement of the moving guide rail, obtain the data of the vision sensor and determine the movement direction of the moving guide rail according to the data of the vision sensor; wherein, the movement direction of the moving guide rail includes a first direction and a second direction, and the first direction is for opening the door, and the second direction is for closing the door;
[0030] Obtain the data of the current vision sensor, determine the number of windows in the current corresponding grille according to the data of the current vision sensor, and then determine the current position of the door according to the number of windows.
[0031] Compared with the prior art, the self-opening refrigerator arranges two support rails symmetrically about the axis in the depth direction of the box body and connects them to the support installed on the door, so that the two support rails can have a supporting force on the door at the axis through the support, and this supporting force coincides with the center of gravity of the door. Such a setting method can ensure that the door can be supported at the position of its center of gravity, thereby avoiding the door from tilting in the length direction of the refrigerator relative to the axis and affecting the user experience; and a driving member is installed on the support rail to be able to drive the support rail by the driving member and drive the door to move relative to the box body, and the self-opening function of the refrigerator is realized while avoiding the offset of the center of gravity of the door, improving the user experience.

[0052] Please refer to Figures 1 to 11, this application provides a self-opening refrigerator 100, which includes a box body 10, a box door 20 and a support rail unit 30. Among them, the box body 10 has a chamber 12 with an opening 11 provided, and along the height direction z of the box body, the chamber 12 has two inner walls 13, and the two inner walls 13 are arranged oppositely and are respectively configured as a first inner wall 131 and a second inner wall 132; the box door 20 is used to open / close the opening 11; the support rail unit 30 includes support rails 31 and a driving member 33. Two support rails 31 are provided, one of the support rails 31 is installed on the first inner wall 131, and the other support rail 31 is installed on the second inner wall 132, and the two support rails 31 are symmetrically arranged with the depth direction y of the box body 10 as the axis, and each support rail is connected to the box door 20. The driving member 33 is installed on the support rail 31 and can drive the support rail 31 to move, so as to drive the box door 20 to move relative to the box body 10 to open / close the opening 11.
[0053] It should be noted that the support rails 31 of the existing self-opening refrigerator 100 are usually arranged on the two inner side walls in the length direction x of the box body 10 and are connected to the box door 20. In this setting, the center of gravity of the box door 20 is on the support horizontal line of the support rails 31, that is, on the horizontal plane perpendicular to the height direction z of the box body 10 at the support rails 31. However, in the actual production and installation process of the self-opening refrigerator 100, due to the assembly error of the box door 20 or the uneven foaming density, the center of gravity of the box door 20 will not be on the above-mentioned horizontal plane, that is, the center of gravity of the box door 20 will shift on both sides in the length direction x of the box body 10, resulting in the box door 20 being relatively inclined on both sides in the length direction x of the box body 10, affecting the user experience. In this application, by symmetrically arranging the two support rails 31 with the depth direction y of the box body 10 as the axis and connecting them to the supports on the box door 20, in this way, the two support rails 31 are at the central axis position of the box door 20 in the length direction x of the box body 10, that is, the two support rails 31 give the box door 20 a supporting force at the central axis position. At this time, this supporting force coincides with the center of the box door 20, so that it can be ensured that the box door 20 can be supported at the position of its center of gravity (central axis position), thus avoiding the box door 20 from tilting relative to the central axis in the length direction x of the box body 10 and affecting the user experience. Moreover, the provided support 32 can increase the connection stability between the support rail 31 and the box door 20, thereby ensuring the smooth movement of the box door 20 relative to the box body 10 and avoiding its deviation during the movement process and affecting the user experience; at the same time, a driving member 33 is installed on the support rail 31 to be able to use the driving member 33 to drive the support rail 31 and drive the box door 20 to move relative to the box body 10. Under the condition of avoiding the deviation of the center of gravity of the box door 20, the self-opening function of the refrigerator is realized, improving the user experience.
[0054] Here, a drawer is also provided on the support rail 31 of the existing self-opening refrigerator 100. Since the weights of the items placed in the drawer in the length direction x parallel to the cabinet 10 are different, the position of the support plane of the support rail 31 is offset relative to the plane perpendicular to the height direction of the cabinet 10, which will also cause the door 20 to be relatively inclined on both sides in the length direction x of the cabinet 10, affecting the user experience. Therefore, in an embodiment of the present application, no drawer is provided on the support rail 31 to avoid the influence on the support of the door 20 by the support rail 31 due to the different weights of the items placed in the drawer in the length direction x parallel to the cabinet 10.
[0055] Further, along the height direction z of the cabinet, the first inner wall 131 is located above the second inner wall 132.
[0056] As Figures 2 to 10 shown, each support rail 31 includes a fixed rail 311 and a movable rail 312. The fixed rail 311 is installed on the corresponding inner wall and has a guide groove 3111. One end of the movable rail 312 extends into the guide groove 3111 and is slidably connected to the guide groove 3111, and the other end is connected to the door 20. Here, the provided guide groove 3111 has a guiding effect on the movable rail 312, enabling the movable rail 312 to stably drive the door 20 to move along the direction of the guide groove 3111 without shaking or movement offset, thereby avoiding the phenomenon of the door 20 tilting or the center of gravity shifting during movement.
[0057] Here, the width of the fixed rail 311 in the length direction of the cabinet 10 is D1, and the width of the movable rail 312 in the length direction of the cabinet 10 is D2. Both D1 and D2 are set to be greater than 120 mm to ensure the connection stability between the fixed rail 311 and the cabinet 10, between the fixed rail 311 and the movable rail 312, and between the movable rail 312 and the door 20, and to ensure the supporting force of the support rail 31 on the door 20, further avoiding the center of gravity shift of the door 20.
[0058] In an embodiment, referring to Figures 8 to 10, along the depth direction y of the box body, a driving groove 3121 is provided on the moving guide rail 312, and driving teeth 3122 are provided on the wall surface of the driving groove 3121. A driving wheel 331 is installed on the driving member 33, and the driving wheel 331 meshes with the driving teeth 3122. Among them, the driving member 33 is installed on the fixed guide rail 311 and is in transmission connection with the moving guide rail 312. In this way, the moving guide rail 312 can drive the box door 20 to move relative to the box body 10 by the transmission cooperation between the driving wheel 331 and the driving teeth 3122. In this way, only the installation space for the driving member 33 needs to be provided on the support rail 31, and the self-opening function of the refrigerator can be realized only through the structural cooperation of the support rail 31. There is no need to additionally provide a space for installing the driving member 33 and a push rod structure, the production cost is lower and the structure is simpler; and the gear transmission of the box door 20 can more accurately control the transmission ratio compared with the push rod structure, so as to accurately control the opening or closing action of the box door 20, further avoiding the deviation of the box door 20 during the movement process, which affects the user experience, and the gear has higher wear resistance and fatigue resistance and can be used repeatedly for a long time, thereby increasing the service life of the self-opening refrigerator 100.
[0059] Here, the driving member 33 can be installed on the support rail 31 by screws, and gaskets 332 are provided between the driving wheel 331 and the moving guide rail 312, and between the moving guide rail 312 and the fixed guide rail 311. The screws are arranged through the gaskets 332 installed on the support rail 31. In this way, through the buffering and self-lubricating effects of the gasket, the screw fixation has buffering and the driving member 33 can operate stably.
[0060] Preferably, the total stroke of the driving teeth 3122 is L, and L>300mm is set so as to realize the automatic opening and closing functions of the box door 20 relative to the box body 10 throughout the process by the forward and reverse rotation of the driving member 33.
[0061] Please continue to refer to Figure 6 , along the length direction x of the box body 10, a flange 3123 is provided on the side surface of the moving guide rail 312, and the end of the flange 3123 away from the moving guide rail 312 abuts against the wall surface of the guide groove 3111 in the length direction x of the box body 10. In this way, the contact area between the end surface of the moving guide rail 312 and the wall surface of the guide groove 3111 can be reduced through the setting of the flange 3123, so as to reduce the frictional resistance of the fixed guide rail 311 on the moving guide rail 312 during the movement, further improving the stability of the box door 20 during the movement and avoiding tilting during the movement process.
[0062] Here, an arc surface is provided at the end of the flange 3123 away from the moving guide rail 312.
[0063] Such as Figures 2 to 8As shown, the bracket 32 is provided with overlapping flanges 321 at both ends in the height direction z of the box body 10. The overlapping flanges 321 are overlapped and connected with the moving guide rails 312 at their corresponding ends to improve the connection stability between the bracket 32 and the moving guide rails 312.
[0064] Here, the overlapping flanges 321 and the moving guide rails 312 can be connected and fixed by means such as screws, rivets and welding, so that the bracket 32 and the moving guide rails 312 are kept on the same height plane, further making the center of gravity of the box door stably in this plane and preventing the box door from tilting.
[0065] In an embodiment, the bracket track unit 30 further includes balls 34. Along the height direction z of the box body, the moving guide rail 312 has a first surface 3124 and a second surface 3125. Balls 34 are provided between the first surface 3124 and the wall surface of the guide groove 3111, and between the second surface 3125 and the wall surface of the guide groove 3111. Here, the balls 34 can roll and contact with the fixed guide rail 311 and the moving guide rail 312 and slide freely between them. Thus, the setting of the balls 34 can increase the smoothness of the movement of the moving guide rail 312 and also enable precise cooperation between the moving guide rail 312 and the fixed guide rail 311.
[0066] In an embodiment, an inner lining reinforcement 35 is provided inside the box body 10 at the corresponding positions of the first inner wall 131 and / or the second inner wall 132. The inner lining reinforcement can be fixed inside the box body 10 by the foaming material of the box body 10 (i.e., fixed between the outer wall of the box body 10 and the box liner), and is connected and fixed with the bracket track 31 so that the bracket track 31 can be stably assembled to the box body 10. Thus, through the cooperation of the inner lining reinforcement and the bracket track 31, it is possible to prevent the box body 10 from tilting due to unstable installation during movement, so that the center of gravity of the box door remains stable.
[0067] As Figures 9 to 11As shown, the support rail unit 30 further includes a vision sensor 36 and a grille 37. The vision sensor 36 is mounted on the fixed guide rail 311 and is in signal connection with the driving member 33. The grille 37 is arranged on the moving guide rail 312. The grille 37 is configured into N groups, and the N groups of grilles 37 are arranged at equal intervals along the length direction x of the moving guide rail 312. Each group of grilles 37 includes M windows 371. Along the depth direction y of the box body 10 from the box door 20 to the box body 10, the number of windows 371 in the N groups of grilles 37 gradually increases or decreases. Wherein, N and M are positive integers, and N≥2, M≥1. In this way, the number of windows 371 of the grille 37 can be recognized by the provided vision sensor 36. With the setting that the number of windows 371 of the N groups of grilles 37 gradually increases or decreases, the precise positioning of the fixed guide rail 311 by the vision sensor 36 can be realized, and through the signal connection between the vision sensor 36 and the driving member 33, the vision sensor 36 can feedback the positioning signal to the driving member 33, so as to precisely control the opening or closing speed of the box door 20 and the position of the box door 20 relative to the box body 10.
[0068] Exemplarily, referring to Figure 10 , in this embodiment, a total of ten groups of grilles 37 are provided, and the group numbers of the ten groups of grilles 37 in the length direction x of the moving guide rail 312 from the position close to the box door 20 to the position far from the box door 20 are group n1, group n2, group n3, group n4, group n5, group n6, group n7, group n8, group n9, and group n10 in sequence. Wherein, the number of windows 371 of the group n1 grille 37 is one, the number of windows 371 of the group n2 grille 37 is two, the number of windows 371 of the group n3 grille 37 is three, the number of windows 371 of the group n4 grille 37 is four, the number of windows 371 of the group n5 grille 37 is five, the number of windows 371 of the group n6 grille 37 is six, the number of windows 371 of the group n7 grille 37 is seven, the number of windows 371 of the group n8 grille 37 is eight, the number of windows 371 of the group n9 grille 37 is nine, and the number of windows 371 of the group n10 grille 37 is ten.
[0069] Here, the vision sensor 36 can be set as an infrared sensor, an ultrasonic sensor, a laser sensor, a TOF sensor, etc.
[0070] Such as Figure 12 As shown, the present application also provides a refrigerator self-opening method. The refrigerator self-opening method is implemented based on the self-opening refrigerator 100 in any of the above embodiments. The method includes the following steps:
[0071] Step S100, based on the movement of the moving guide rail 312, obtain the data of the vision sensor 36 and determine the movement direction of the moving guide rail 312 according to the data of the vision sensor 36. Wherein, the movement direction of the moving guide rail 312 includes a first direction and a second direction, and the first direction is for opening the door, and the second direction is for closing the door.
[0072] Step S200: Obtain the data of the current vision sensor 36, determine the number of windows 371 in the current corresponding grille 37 according to the data of the current vision sensor 36, and then determine the current position of the box door 20 according to the number of windows 371.

These steps can be operated sequentially or in other orders, and the specific operation steps can be determined according to the actual situation.
[0074] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope recorded in this specification.
