[0085] Figure 3 As shown in Figs. 1 and 2, in some embodiments, the refrigerator can include a second drawer 22. The second drawer 22 can be provided on the side adjacent to the first drawer 21. The second drawer 22 can serve as another storage space, so that the user can store different types of items as needed, improving the space utilization and storage flexibility. Figure 4 ​​​​As shown, in some embodiments, the refrigeration compartment 201 may have a second sidewall 204. The first sidewall 202 and the second sidewall 204 may be respectively disposed on both sides of the front opening.

[0086] In some embodiments, a second guide groove 205 may be provided on the second sidewall 204 at a position corresponding to the first guide groove 203. The second guide groove 205 allows the second drawer 22 to be installed on the side near the second sidewall 204.

[0087] like Figure 3 and Figure 5 As shown, in some embodiments, the side of the guide rail bracket 4 facing the second sidewall 204 may be provided with a second slide groove 402. The second slide groove 402 allows the second drawer 22 to be installed on the side near the guide rail bracket 4.

[0088] In some embodiments, the first slide rail 401 and the second slide rail 402 may be located on opposite sides of the guide rail bracket 4 at the same height. One side of the second drawer 22 is mounted on the second guide groove 205, and the other side of the second drawer 22 is mounted on the second slide rail 402.

[0089] It should be noted that when the refrigeration compartment 201 has a first drawer 21 and a second drawer 22 arranged adjacent to each other, if the liner bulges after foaming, especially if the front of the liner bulges out significantly, the liner may cause the guide rail bracket 4 to move upwards. This upward movement of the guide rail bracket 4 will cause the first drawer 21 and the second drawer 22 to move upwards, resulting in the openings of the first drawer 21 and the second drawer 22 appearing as an "outward octagonal" shape. In this embodiment, a first sliding groove 401 and a second sliding groove 402 are respectively provided at the same height on both sides of the guide rail bracket 4, so that the adjacent sides of the first drawer 21 and the second drawer 22 are at the same height. Furthermore, a second guide groove 205 is provided at the corresponding position of the second side wall 204 and the first guide groove 203, so that the distant sides of the first drawer 21 and the second drawer 22 are at the same height. In this way, the guide rail bracket 4 can be driven to move up and down by the bracket adjustment component 5, so that the guide rail bracket 4 moves to the first guide groove 203 and the first slide groove 401 at the same height, which can align the first drawer 21 and the second drawer 22. This can effectively solve the problem of the first drawer 21 and the second drawer 22 being outward or inward due to the foaming of the box body. This not only improves the overall aesthetics of the product, but also enhances the user experience. Users are no longer bothered by the appearance of the drawers during use, which improves satisfaction and product user experience.

[0090] Figure 6 for Figure 2 A schematic diagram of the bottom of the middle chamber; Figure 7 for Figure 6 A partial exploded view;Figure 8 For Figure 7 A local enlarged view of A.

[0091] Referring to Figure 6 and Figure 7 In some embodiments, the refrigerator can include a bracket adjusting assembly 5. The bracket adjusting assembly 5 can be in transmission connection with the guide rail bracket 4 and can drive the guide rail bracket 4 to move up and down so that the first guide groove 203 and the first sliding groove 401 are located at the same height.

[0092] It should be noted that when the foaming of the box body causes the front part to bulge, causing the guide rail bracket 4 and the first drawer 21 to be displaced, at this time, the two sides of the first drawer 21 cause an appearance problem due to being located at different heights, affecting the user's use experience. The technical solution of the present application controls the bracket adjusting assembly 5, and then adjusts the height of the guide rail bracket 4, so that the first guide groove 203 and the first sliding groove 401 are located at the same height again. In this way, the first drawer 21 installed between the two can maintain the same height on both sides, thereby solving the problem of affecting the visual appearance. Moreover, compared with adjusting the foaming mold, the present application provides higher flexibility for adjusting the installation of the first drawer 21 by setting the bracket adjusting assembly 5, which not only can more accurately control the position of the guide rail bracket 4, but also can more efficiently make the heights of the two sides of the drawer consistent to improve the visual appearance, and can also reduce the scrap of the box body caused by improper adjustment of the mold, thereby reducing the production cost.

[0093] Referring to Figure 6 and Figure 7 In some embodiments, the rear end of the guide rail bracket 4 can be rotatably connected to the bottom of the refrigeration compartment 201, and the front end of the guide rail bracket 4 is in transmission connection with the bracket adjusting assembly 5. Among them, by designing the rear end of the guide rail bracket 4 to be rotatably connected to the bottom of the refrigeration compartment 201, the rear end of the guide rail bracket 4 can maintain a certain stability during the process of the bracket adjusting assembly 5 controlling the guide rail bracket 4 to move up and down.

[0094] In some embodiments, the rotatable connection can be realized by a hinge, a rotating shaft or other similar mechanical structure, to ensure that the guide rail bracket 4 does not come off its installation position during movement.

[0095] Referring to Figure 8 shown, in some embodiments, the bracket adjusting assembly 5 can drive the front end of the guide rail bracket 4 to move up and down so that the first guide groove 203 and the first sliding groove 401 are located at the same height.

[0096] It should be noted that, during refrigerator use, the front end of the first drawer 21 or the front end of the second drawer 22 is a crucial visual factor. Therefore, users primarily judge whether the sides of the first drawer 21 are flush by observing the front end, while the rear end is difficult to observe. Thus, the bracket adjustment assembly 5 can drive the front end of the guide rail bracket 4 to move up and down, thereby aligning the front ends of the first guide groove 203 and the first sliding groove 401 on the same horizontal plane. In this embodiment, the structure controlling the rotation of the guide rail bracket 4 around the rear fulcrum is simple, lower in cost, and can more effectively ensure that the sides of the first drawer 21 are flush. When the second drawer 22 is installed, it can also ensure that the sides of the first drawer 21 and the second drawer 22 are flush.

[0097] In some other embodiments, the guide rail bracket 4 can also move up and down as a whole. This allows the guide rail bracket 4 to move the first drawer 21 and the second drawer 22, so that the two sides of the first drawer 21 and the two sides of the second drawer 22 can be flush.

[0098] In some embodiments, the bracket adjustment assembly 5 may include two sets. One set of bracket adjustment assemblies 5 is drivenly connected to the front end of the guide rail bracket 4. The other set of bracket adjustment assemblies 5 is drivenly connected to the rear end of the guide rail bracket 4. The two sets of bracket adjustment assemblies 5 can drive the front end and the rear end of the guide rail bracket 4 to move up and down respectively, so that the first guide groove 203 and the first sliding groove 401 are at the same height.

[0099] It should be noted that one set of bracket adjustment components 5 is connected to the front end of the guide rail bracket 4, enabling it to drive the front end of the guide rail bracket 4 to move up and down, thereby adjusting the height of the front end of the guide rail bracket 4 to ensure the height consistency of the first guide groove 203 and the first sliding groove 401 at the front end position. The other set of bracket adjustment components 5 is connected to the rear end of the guide rail bracket 4, similarly enabling it to drive the rear end of the guide rail bracket 4 to move up and down. By designing the bracket adjustment components 5 as two sets, the height of both the front and rear ends can be adjusted simultaneously, allowing both the front and rear ends of the guide rail bracket 4 to be controlled independently. This achieves more precise and flexible height adjustment, which helps ensure that the guide rail bracket 4 remains stable and level throughout its entire length.

[0100] like Figure 8 As shown, in some embodiments, the bracket adjustment assembly 5 may include a drive motor 51. The drive motor 51 can serve as the power source for the bracket adjustment assembly 5, responsible for providing the driving force required to adjust the height of the guide rail bracket 4.

[0101] In some embodiments, the support adjusting assembly 5 can include a first engaging part 52. The driving motor 51 can be in transmission connection with the first engaging part 52. The guide rail support 4 can be provided with a second engaging part 41, and the first engaging part 52 is engaged with the second engaging part 41.

[0102] Specifically, the engagement transmission between the support adjusting assembly 5 and the guide rail support 4 can efficiently convert the rotary motion of the motor into the linear motion of the guide rail support 4, thereby improving the transmission efficiency and accuracy. Specifically, the driving motor 51 can drive the second engaging part 41 to move up and down through the first engaging part 52, so as to drive the guide rail support 4 to move up and down through the second engaging part 41. Specifically, when the driving motor 51 is started, the driving motor 51 can drive the first engaging part 52 to move, and then drive the second engaging part 41 to move up and down along the vertical direction through the engagement. Since the second engaging part 41 is connected with the guide rail support 4, when the second engaging part 41 moves up and down, the second engaging part 41 can drive the guide rail support 4 to move together. In this way, by controlling the rotation direction and speed of the driving motor 51, the accurate adjustment of the height of the guide rail support 4 can be realized.

[0103] As shown in Figure 8 , in some embodiments, the first engaging part 52 can be a gear. The gear is connected with the output end of the driving motor 51. When the driving motor 51 is started, the driving motor 51 can drive the gear to rotate together.

[0104] As shown in Figure 8 , in some embodiments, the second engaging part 41 can be a rack. The rack can be engaged with the gear, and the driving motor 51 can drive the gear to rotate, so as to drive the rack to move up and down, and drive the guide rail support 4 to move up and down. In this way, the rotary motion of the gear can be converted into the linear motion of the rack, and then drive the guide rail support 4 fixedly connected therewith to move together, so as to realize the adjustment of the height of the guide rail support 4.

[0105] As shown in Figure 6 and Figure 7 , in some embodiments, the refrigerator further includes a first mounting shell 61. The first mounting shell 61 is connected to the bottom outer side of the box body. The gear and the driving motor 51 can be arranged in the cavity of the first mounting shell 61. By arranging the first mounting shell 61 and then arranging the gear and the driving motor 51 in the first mounting shell 61, the influence of the external environment on the transmission structure of the support adjusting assembly 5 can be effectively isolated, and the installation stability of the support adjusting assembly 5 can be maintained during the movement of the guide rail support 4.

[0106] It should be noted that in the technical scheme of the present application, during the process of adjusting the up and down movement of the guide rail bracket 4 by controlling the bracket adjusting assembly 5, the guide rail bracket 4 can drive the first drawer 21 to move up and down, thereby improving the distance between the first drawer 21 and the bottom side wall of the refrigeration compartment 201, so as to avoid the inconsistent height position of the first drawer 21 on both sides in the refrigeration compartment 201 due to the foaming of the box body. Thus, the first mounting shell 61 is connected to the bottom outside of the box body, the bracket adjusting assembly 5 is fixed to the bottom of the box body, and then the up and down movement of the guide rail bracket 4 relative to the bottom of the refrigeration compartment 201 is controlled through the meshing transmission relationship between the bracket adjusting assembly 5 and the guide rail bracket 4, thereby solving the problem caused by the inconsistent height of the two sides of the drawer due to the foaming of the box body.

[0107] In some embodiments, the first mounting shell 61 can be located in the foaming layer of the box body. In this way, the bracket adjusting assembly 5 is also located in the foaming layer, which can avoid the cold air in the refrigeration compartment 201 from leaking through the connection between the bracket adjusting assembly and the guide rail bracket 4.

[0108] As shown in Figure 8 , in some embodiments, the bottom of the box body can be provided with a first perforation 206. The drive motor 51 can be arranged inside the first mounting shell 61. The part of the rack that extends into the first mounting shell 61 through the first perforation 206 is engaged with the gear. Under the action of the drive motor 51, the rack can extend into the first mounting shell 61 through the first perforation 206 and move up and down along the first perforation 206, realizing the transmission effect.

[0110] As shown in Figure 9 and Figure 10 , in some embodiments, the first mounting shell 61 can be provided with a clamping rib 63. The clamping rib 63 can be clamped with the drive motor 51, so as to fix the drive motor 51 in the cavity of the first mounting shell 61.

[0111] In some embodiments, the first mounting shell 61 can be provided with a plurality of clamping ribs 63. The plurality of clamping ribs 63 can include a first clamping rib 631 and a second clamping rib 632 arranged opposite to each other. The clamping ribs arranged opposite to each other can position the up and down position of the drive motor 51.

[0112] In some embodiments, the first mounting shell 61 can be provided with a plurality of clamping ribs 63. The plurality of clamping ribs 63 can include a third clamping rib 633 and a fourth clamping rib 634 arranged opposite to each other. The clamping ribs arranged opposite to each other can position the left and right positions of the driving motor 51.

[0113] As shown in Figure 9 , in some embodiments, the first mounting shell 61 can be provided with a positioning column 64. The driving motor 51 can be provided with a positioning hole 601. The positions of the positioning column 64 and the positioning hole 601 can correspond to each other, so that the positioning column 64 is arranged in the positioning hole 601, thereby fixing the driving motor 51 in the first mounting shell 61.

[0114] As shown in Figure 7 , in some embodiments, the refrigerator can include a second mounting shell 62. The second mounting shell 62 can be connected to the bottom outer side of the tank 2, and can be used to mount and support the rotating connection part of the guide rail support 4.

[0115] Figure 11 For Figure 2 , a perspective view of the guide rail support is shown; Figure 12 , a partial enlarged view of B of Figure 11 ; Figure 13 , a schematic view of the connection of the guide rail support and the support adjusting assembly; Figure 14 , an exploded view of Figure 13 ; Figure 15 , a partial enlarged view of C of Figure 14 ; Figure 16 , a partial enlarged view of D of Figure 7 .

[0116] It should be noted that, in order to conveniently show the schematic view of the connection of the guide rail support and the support adjusting assembly, Figure 11 and Figure 12 the tank structure is hidden.

[0117] Please refer to Figure 11 and Figure 12 , in some embodiments, the second mounting shell 62 can be provided with a rotating pin 7. The rotating pin 7 can be connected with the rotating connection part of the guide rail support 4. In this way, the rotating pin 7 serves as the center axis of the rotation of the guide rail support 4, and the second mounting shell 62 can support the rotation of the rotating pin 7, so that the rotating pin 7 can bear the weight of the guide rail support 4 and the articles carried thereon and the moment generated during rotation.

[0118] As shown in Figure 14 , in some embodiments, the rear end of the guide rail support 4 can be provided with a rotating connection part 42. The rotating connection part 42 can be used to rotate with the rotating pin 7.

[0119] As shown in Figure 14 andFigure 15 As shown, in some embodiments, the rotating connection portion 42 may be provided with a rotating hole 403. Specifically, the rotating connection portion 42 at the rear end of the guide rail bracket 4 is provided with a rotating hole 403 to cooperate with the rotating pin 7.

[0120] like Figure 16 As shown, in some embodiments, the bottom of the inner box 2 may be provided with a second through hole 209. The rotating connecting part 42 can extend into the second mounting shell 62 through the second through hole 209 and be rotatably connected to the rotating pin 7 through the rotating hole 403. The guide rail bracket 4 can rotate around the rotating pin 7 and move up and down relative to the inner box so that the first guide groove 203 and the first sliding groove 401 are at the same height. By providing a second through hole at the bottom of the inner box 2, the second through hole allows the rotating connecting part 42 of the guide rail bracket 4 to pass through and connect with the rotating pin 7 in the second mounting shell 62. Supported by the rotating pin 7, the guide rail bracket 4 can rotate and move up and down around it. In this way, the guide rail bracket 4 can be height adjusted while maintaining a certain angle to ensure that the first guide groove 203 and the first sliding groove 401 are at the same height, so that the sides of the first drawer 21 and the second drawer 22 are aligned.

[0121] In some embodiments, the bracket adjustment assembly 5 can be manually adjusted. This allows the operator to adjust it according to the actual position and requirements of the guide rail bracket 4.

[0122] In some embodiments, the bracket adjustment assembly 5 may be automatically adjustable.

[0123] In some embodiments, the refrigerator may include a position detection mechanism, which can be used to monitor the height relationship between the first guide groove 203 and the first slide groove 401. By detecting the relative position of the two in real time, the mechanism can provide corresponding feedback information to ensure that the two sides of the first drawer 21, or the height of the first drawer 21 and the second drawer 22 installed in the refrigerator liner, are consistent.

[0124] Figure 17 for Figure 4 A magnified view of a portion at point E.

[0125] Please see Figure 4 and Figure 17 As shown, in some embodiments, the position detection mechanism may include a first sensing component 81. The first sensing component 81 may be disposed on the first guide groove 203. The first sensing component 81 may be used to detect the specific position or height information of the first guide groove 203.

[0126] Please see Figure 14As shown in some embodiments, the position detection mechanism can include a second sensing assembly 82. The second sensing assembly 82 can be arranged on the first sliding groove 401. The second sensing assembly 82 can be used to detect the specific position or height information of the first sliding groove 401.

[0127] Wherein, the position detection mechanism can generate a first position signal when the first sensing assembly 81 and the second sensing assembly 82 are at different heights. When the first sensing assembly 81 and the second sensing assembly 82 detect that there is a difference in height between them, that is, the first sensing assembly 81 and the second sensing assembly 82 are not on the same horizontal plane, the position detection mechanism generates a first position signal, which can be received and processed by the control system to trigger the corresponding support adjustment assembly 5 to automatically adjust the height of the guide rail support 4.

[0128] As shown in some embodiments, the first sensing assembly 81 can be arranged at the front end of the first guide groove 203. Figure 4 and Figure 17 As shown in some embodiments, the second sensing assembly 82 can be arranged at the front end of the first sliding groove 401.

[0129] As shown in some embodiments, the first sensing assembly 81 can be arranged at the front end of the first guide groove 203. Figure 13 and Figure 14 As shown in some embodiments, the second sensing assembly 82 can be arranged at the front end of the first sliding groove 401.

[0130] It should be noted that the first sensing assembly 81 and the second sensing assembly 82 can be arranged at the corresponding positions of the first guide groove 203 and the first sliding groove 401 respectively, so that when the position detection mechanism sends out the first position signal, the support adjustment assembly 5 adjusts the height of the guide rail support 4, and then the front end of the first drawer 21 is located at the same position height, which can more efficiently complete the position adjustment process.

[0131] In other embodiments, the first sensing assembly 81 can be arranged at the middle position of the first guide groove 203. The second sensing assembly 82 can be correspondingly arranged at the middle position of the first sliding groove 401.

[0132] In some embodiments, the refrigerator can include a control mechanism (not shown in the figure). The control mechanism can be electrically connected with the guide rail support 4. The control mechanism can be responsible for receiving the signal sent by the position detection mechanism, and according to the signal content, the core component of the support adjustment assembly 5 is adjusted accordingly. Wherein, the control mechanism and the support adjustment assembly 5 establish an electrical control connection, which can control the up and down movement of the guide rail support 4 driven by the support adjustment assembly 5 in real time and accurately.

[0133] In some embodiments, the control mechanism can receive the first position signal and drive the rail bracket 4 to move up and down so that the first guide groove 203 and the first sliding groove 401 are at the same height. In this way, the operator does not need to manually adjust the height of the rail bracket 4, and the control mechanism can automatically complete the adjustment process according to the first position signal, which not only improves the convenience of use, but also avoids problems caused by improper manual adjustment.

[0134] In some embodiments, one of the first sensing assembly 81 and the second sensing assembly 82 can be a sensor, and the other of the first sensing assembly 81 and the second sensing assembly 82 can be a sensing piece. The sensor can be responsible for sending and receiving signals to detect the relative position relationship between the sensor and the sensing piece. The sensing piece, as a component used in cooperation with the sensor, can reliably trigger the sensor to generate a first position signal when the sensor and the sensing piece are at different heights.

[0135] In some embodiments, the sensor can be, for example, an optical sensor, a Hall sensor, a magnetic induction sensor, etc., which can be selected according to design requirements and actual application scenarios.

[0136] In some embodiments, when the sensor and the sensing piece are at different heights, the sensor generates a first position signal to control the control mechanism to move the rail bracket 4 up and down based on the first position signal. In this way, the control mechanism can more accurately control the stop position of the rail bracket 4 to ensure the height consistency between the first guide groove 203 and the first sliding groove 401. During the adjustment process, if the rail bracket 4 continues to move beyond the target position, it may cause the two sides of the first drawer 21 to be misaligned, or even cause the first drawer 21 to slide poorly or be damaged. By detecting the second position signal and controlling the stop motion, the occurrence of such over-adjustment can be avoided.

[0137] As shown in FIGS. Figure 3 and Figure 17 In some embodiments, the refrigerator can include a first mounting cover 91. The first mounting cover 91 can be mounted on a first mounting opening 207 formed in the sidewall of the first guide groove 203, and the first sensing assembly 81 can be arranged on the sidewall of the first mounting cover 91 away from the refrigeration compartment 201. In this way, the first sensing assembly 81 is arranged on the sidewall of the first mounting cover 91 away from the refrigeration compartment 201, which can avoid direct exposure of the first sensing assembly 81 to the low-temperature environment of the refrigeration compartment 201, thereby prolonging the service life of the sensing assembly. Further, the first mounting cover 91 can provide protection for the first sensing assembly 81 to prevent damage from the external environment, thereby improving the reliability and service life of the first sensing assembly 81.

[0138] In some embodiments, the first mounting cover 91 can be fixed on the first mounting port 207 by connection methods such as bolts, buckles, adhesives, etc.

[0139] In some embodiments, the first mounting cover 91 can be provided with a first buckle 911. The first buckle 911 can fix the first sensing assembly 81 on the first mounting cover 91, and can avoid the first sensing assembly 81 from moving in the refrigerator, thereby improving the installation stability of the first sensing assembly 81.

[0140] As shown in FIG. 1, Figure 14 In some embodiments, the refrigerator can include a second mounting cover 92. The second mounting port 208 is formed on the side wall of the first sliding groove 401, and the second mounting cover 92 is mounted on the second mounting port 208. The second sensing assembly 82 is arranged on the side wall of the second mounting cover 92 away from the first drawer 21. The second sensing assembly 82 is arranged on the side wall of the second mounting cover 92 away from the first drawer 21, which can avoid the second sensing assembly 82 from being directly exposed to the low-temperature environment of the refrigeration compartment 201, thereby prolonging the service life of the sensing assembly. Further, the second mounting cover 92 can protect the second sensing assembly, preventing it from being damaged by the external environment, thereby improving the reliability and service life of the second sensing assembly 82.

[0141] In some embodiments, the second mounting cover 92 can be fixed on the second mounting port 208 by connection methods such as bolts, buckles, adhesives, etc.

[0142] As shown in FIG. 1, Figure 14 In some embodiments, the second mounting cover 92 can be provided with a second buckle 921. The second buckle 921 can fix the second sensing assembly 82 on the second mounting cover 92, and can avoid the second sensing assembly 82 from moving in the refrigerator, thereby improving the installation stability of the second sensing assembly 82.

[0143] As shown in FIG. 1, Figure 5 In some embodiments, the first side wall 202 can be provided with a left drawer guide rail 23. The left drawer guide rail 23 can be recessed to form a first guide groove 203 on the side facing the first drawer 21. The left drawer guide rail 23 is recessed on the side facing the first drawer 21 to form the first guide groove 203, which can provide a mounting position for the first drawer 21.

[0144] As shown in FIG. 1, Figure 4 In some embodiments, the second side wall 204 can be provided with a right drawer guide rail 24. The right drawer guide rail 24 can be recessed to form a second guide groove 205 on the side facing the second drawer 22. The right drawer guide rail 24 is recessed on the side facing the second drawer 22 to form the second guide groove 205, which can provide a mounting position for the second drawer 22.

[0145] In some embodiments, the left drawer guide rail 23 and the right drawer guide rail 24 can be located at the same height position.
