[0096] As shown in the exploded diagram of the power-assisted assembly of the refrigerator in the closed state, Figures 1 to 7 An embodiment of the present application provides a refrigerator 100, comprising:

[0097] a cabinet 110 having a front side and a back side;

[0098] a door body 120 movably connected to the cabinet 110;

[0099] a power-assisted assembly 130 movably arranged on the door body 120, the power-assisted assembly 130 comprising:

[0100] a pulling member 131;

[0101] a power-assisted member 132 movably connected to the pulling member 131;

[0102] the power-assisted assembly 130 has an extended state and a retracted state which can be switched to each other, when the power-assisted assembly 130 is switched from the retracted state to the extended state, the pulling member 131 moves along a first direction, driving the power-assisted member 132 to move along a second direction, and providing power assistance for opening of the door body 120, so that the door body 120 is in an open state;

[0103] when the power-assisted assembly 130 is switched from the extended state to the retracted state, the power-assisted member 132 is configured to move along the first direction, driving the pulling member 131 to move along the second direction, so that the door body 120 is in a closed state;

[0104] wherein the first direction and the second direction are opposite, and the first direction is a direction in which the back side of the cabinet 110 points to the front side of the cabinet 110.

[0105] Through the above setting, that is, the refrigerator 100 of the embodiment of the present application, through the design of the power assisting assembly 130, the user can obtain additional pushing force support when opening the door of the refrigerator 100. When the pulling member 131 is pulled by the user, the power assisting member 132 can push open the door body 120, achieving the power assisting effect. This design reduces the force required by the user to open the door, making it easier to open the door of the refrigerator 100, thereby achieving the opening of the door body 120 with less force, especially suitable for users with less strength or in the case of a heavy refrigerator 100 door. In addition, the moving direction of the power assisting assembly 130 is always consistent with the direction of the user's force, improving the user's comfort when opening the door, conforming to the user's usual opening behavior, and improving the overall user experience, especially in the case of frequent opening and closing of the door.

[0106] It should be noted that, as shown in Figure 7 , the first direction X and the second direction Y.

[0107] It should be noted that the following will specifically describe each structure.

[0108] [Box body 110]

[0109] Referring to Figure 1 and Figure 6 , the refrigerator 100 of the embodiment of the present application can include a box body 110 and a door body 120. The box body 110 can be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. The number of refrigeration compartments can be one or more. When the number of refrigeration compartments is more than one, the multiple refrigeration compartments can be divided into a refrigeration room, a freezing room, or a variable temperature room, etc.

[0110] Exemplarily, the box body 110 can include a box shell and a box liner. The box shell is used to define the outer boundary of the refrigerator 100. The box liner can be arranged in the box shell and connected with the box shell. The box liner can be recessed inward to form a refrigeration compartment. The box shell and the box liner can be filled with a thermal insulation layer, which can thermally insulate the refrigeration compartment, thereby reducing the energy consumption of the refrigerator 100.

[0111] [Door body 120]

[0112] It should be noted that the door body 120 can be connected with the box body 110 for opening or closing the refrigeration compartment. The same refrigeration compartment can correspond to one door body 120. Alternatively, the same refrigeration compartment can also correspond to two door bodies 120.

[0113] In some possible implementation manners of the present application, the door body 120 can be rotatably connected with the box body 110 in the height direction of the box body 110. The door body 120 can be pulled or pushed to rotate relative to the box body 110 to open or close the refrigeration compartment.

[0114] [Assistance assembly 130]

[0115] In some related technologies, the door body 120 in the closed state is affected by the magnetic attraction of the magnetic door seal, the elastic force of the door closer, the clamping force of the flip beam, and the negative pressure generated by low temperature in the box body 110. Various closing forces make it necessary to resist a large resistance in the initial stage of opening the door body 120, increasing the difficulty of opening the door body 120.

[0116] Therefore, the assistance assembly 130 provided by the present application can provide greater thrust to the door body 120 by the design of the pulling member 131 and the assistance member 132 to overcome the resistance in the initial stage of opening the door body 120.

[0117] It should be noted that when the user needs to open the door body 120, the user manually pulls the pulling member 131, so that the pulling member 131 moves in the first direction under the pulling of the user, and in turn drives the assistance member 132 to move in the second direction, so that the assistance member 132 provides assistance to the door body 120 to open, and in turn the door body 120 is pried open to realize opening the door body 120 with a smaller force.

[0118] When the user needs to close the door body 120, the assistance member 132 is configured to move in the first direction, and in turn drives the pulling member 131 to move in the second direction, that is, both return to the original position, and in turn the door body 120 gradually approaches the box body 110 and is in a closed state.

[0119] Figure 8 A structural schematic diagram of a partial assistance assembly of a refrigerator in an open state is provided for the embodiment of the present application, Figure 9 For Figure 8 A partial enlarged view at III in FIG. 10, Figure 10 An exploded schematic diagram of an assistance assembly of a refrigerator in an open state is provided for the embodiment of the present application.

[0120] As Figures 1 to 10 shown, in some embodiments, the assistance assembly 130 further includes a transmission member 133 rotatably arranged between the pulling member 131 and the assistance member 132.

[0121] The above technical solution has the following advantages or beneficial effects: The addition of the transmission member 133 makes the force transmission between the pulling member 131 and the assistance member 132 more efficient and smooth. Through the rotation of the transmission member 133, the linear motion of the pulling member 131 can be effectively converted into the required motion form of the assistance member 132, improving the working efficiency of the entire assistance assembly 130. In addition, through the rotation of the transmission member 133, the motion conversion between the pulling member 131 and the assistance member 132 is smoother, reducing friction and resistance in the motion process, making the opening and closing of the refrigerator 100 door more smooth.

[0122] It should be noted that the arrangement of the transmission member 133 can provide additional support and stability between the pulling member 131 and the assisting member 132, reducing the shaking or deviation of the assembly during operation, ensuring the reliability and durability of the assisting assembly 130.

[0123] In some embodiments, the introduction of the transmission member 133 provides more flexibility for the design of the assisting assembly 130. The shape, size and mounting position of the transmission member 133 can be adjusted according to specific needs to achieve different mechanical effects and motion paths, suitable for different types and sizes of refrigerator 100 doors.

[0124] As shown in Figures 1 to 10 In some embodiments, the transmission member 133 is a rotating arm 134, which is arranged to rotate relative to the door body 120, and has a first clamping member 1341 and a second clamping member 1342. The pulling member 131 has a first clamping groove 1312, and the first clamping member 1341 is clamped with the first clamping groove 1312.

[0125] It should be noted that the cooperation between the first clamping groove 1312 and the first clamping member 1341 makes the installation and disassembly between the rotating arm 134 and the pulling member 131 more convenient, improves the safety between the rotating arm 134 and the pulling member 131, and prevents loosening or falling during use.

[0126] The assisting member 132 has a second clamping groove 1322, and the second clamping member 1342 is clamped with the second clamping groove 1322.

[0127] The above technical solution has the following advantages or beneficial effects: through the arrangement of the rotating arm 134, the force transmission path is more explicit and accurate. The design of the first clamping member 1341 and the second clamping member 1342 ensures the stable connection between the pulling member 131 and the assisting member 132, reducing the energy loss in the force transmission process.

[0128] Correspondingly, the cooperation between the second clamping groove 1322 and the second clamping member 1342 makes the installation and disassembly between the rotating arm 134 and the assisting member 132 more convenient, improves the safety between the rotating arm 134 and the assisting member 132, and prevents loosening or falling during use. Further, the structure of the entire assisting assembly 130 is more compact. This design helps to save space and is suitable for application in limited space such as refrigerator 100.

[0129] Specifically, when the assisting assembly 130 is switched from the retracted state to the extended state, the pulling member 131 moves along the first direction, which means that the first clamping slot 1312 moves along the first direction, thereby driving the first clamping piece 1341 to move along the first direction. Meanwhile, the rotating arm 134 rotates through the rotating shaft, and the second clamping piece 1342 at the other end of the rotating arm 134 moves along the opposite direction, that is, the second clamping piece 1342 moves along the second direction, thereby driving the second clamping slot 1322 corresponding to the clamping piece to move along the second direction, that is, driving the assisting piece 132 to move along the second direction. When the assisting piece 132 moves along the second direction, it presses the front end of the box body 110 and provides assistance for opening the door body 120, thereby being able to push the door body 120 open and realize opening the door body 120 with a smaller force.

[0130] As shown in Figure 3 , Figure 4 , Figure 9 and Figure 10 , in some embodiments, the assisting assembly 130 further includes an elastic member 135, which is arranged on the rotating arm 134 and abuts between the assisting piece 132 and the pulling member 131.

[0131] The above technical solution has the following advantages or beneficial effects: the elastic member 135 provides elastic force when the assisting assembly 130 is switched from the extended state to the retracted state, helping the assisting piece 132 to move along the first direction. This design enables the assisting assembly 130 to automatically reset, ensuring that the door of the refrigerator 100 can automatically return to the closed state after being opened, thereby improving the convenience of use.

[0132] When the assisting assembly 130 is switched from the retracted state to the extended state, the pulling member 131 moves along the first direction to press the elastic member 135. When the assisting assembly 130 is switched from the extended state to the retracted state, the elastic member 135 provides elastic force for the assisting piece 132 to move along the first direction.

[0133] It should be noted that the elastic member 135 can store energy during the movement of the assisting assembly 130 and release it when needed. This energy storage and release mechanism improves the energy efficiency of the system, making the operation of the door of the refrigerator 100 more labor-saving and efficient. Through the elastic force of the elastic member 135, the switching between different states of the assisting assembly 130 is more stable and reliable, reducing the shaking or instability caused by inertia or external force.

[0134] In some embodiments, the elastic member 135 can be a torsional spring.

[0135] Specifically, the torsion spring has a more compact structure compared to other types of elastic elements 135, such as compression springs or extension springs. This allows the force assisting assembly 130 to achieve complex functions in a limited space, making it very suitable for application in space-limited devices such as refrigerators 100.

[0136] The torsion spring can efficiently store and release energy in rotational motion. Through its torsional characteristics, the torsion spring can provide stable elastic support when the force assisting assembly 130 switches states, ensuring smooth opening and closing of the door body 120.

[0137] It should be noted that the force assisting assembly 130 can also be designed as follows:

[0138] Figure 11 Fig. 4 is a structural schematic diagram of another partial force assisting assembly in a closed state of a refrigerator according to an embodiment of the present application, Figure 12 Fig. 5 is a partial enlarged view of IV in Fig. 4, Figure 11 Fig. 6 is an exploded schematic diagram of another force assisting assembly in a closed state of a refrigerator according to an embodiment of the present application, Figure 13 Fig. 7 is a structural schematic diagram of another partial force assisting assembly in an open state of a refrigerator according to an embodiment of the present application, Figure 14 Fig. 8 is a partial enlarged view of V in Fig. 7, Figure 15 Fig. 9 is an exploded schematic diagram of another force assisting assembly in an open state of a refrigerator according to an embodiment of the present application. Figure 14 Figure 16 As shown in Fig. 10, in some embodiments, the pulling element 131 has a first rack 1311, the force assisting element 132 has a second rack 1321, and the transmission element 133 is a gear train 136. The opposite gear ends of the gear train 136 are respectively engaged with the first rack 1311 and the second rack 1321, and the moving directions of the first rack 1311 and the second rack 1321 are opposite.

[0139] As shown in Fig. 10, in some embodiments, the pulling element 131 has a first rack 1311, the force assisting element 132 has a second rack 1321, and the transmission element 133 is a gear train 136. The opposite gear ends of the gear train 136 are respectively engaged with the first rack 1311 and the second rack 1321, and the moving directions of the first rack 1311 and the second rack 1321 are opposite. Figures 11 to 16 The above technical solution has the following advantages or beneficial effects: through the engagement of the gear train 136 with the first rack 1311 and the second rack 1321, precise motion control between the pulling element 131 and the force assisting element 132 can be achieved. This design ensures the synchronization and coordination between the two, improving the overall performance of the force assisting assembly 130.

[0140] It should be noted that the gear train 136 can effectively convert the linear motion of the pulling element 131 into the opposite linear motion of the force assisting element 132. Due to the high efficiency of gear transmission, the energy loss of the system is small, improving the working efficiency of the force assisting assembly 130.

[0141]

[0142] ​​The first rack 1311 and the second rack 1321 move in opposite directions. Through the design of the gear train 136 , the pulling member 131 and the assisting member 132 can move in opposite directions.

[0143] In some embodiments, the first rack 1311 may be fixed to the pulling member 131 , or teeth marks may be directly engraved on a side of the pulling member 131 facing the gear train 136 to form a rack.

[0144] Accordingly, in some embodiments, the second rack 1321 may be fixed to the assisting member 132 , or a tooth mark may be directly engraved on the side of the assisting member 132 facing the gear train 136 to form a rack.

[0145] like Figures 11 to 16 As shown, in some embodiments, the gear train 136 includes: a first gear 1361, meshing with the first rack 1311; a second gear 1362, meshing with the first gear 1361; and a third gear 1363, meshing with the second gear 1362 and the second rack 1321, respectively; wherein the first gear 1361 and the third gear 1363 rotate in the same direction, and the first gear 1361 and the second gear 1362 rotate in opposite directions.

[0146] The above technical solution has the following advantages or beneficial effects: Through the design of the first gear 1361, the second gear 1362, and the third gear 1363, the movement between the first rack 1311 and the second rack 1321 can be accurately converted and controlled. The first gear 1361 meshes with the first rack 1311, and the third gear 1363 meshes with the second rack 1321, ensuring the coordinated movement between the two.

[0147] Since the first gear 1361 and the second gear 1362 rotate in opposite directions, and the first gear 1361 and the third gear 1363 rotate in the same direction, this design enables the pulling member 131 and the assisting member 132 to move in opposite directions.

[0148] In some embodiments, the sizes of the first gear 1361 , the second gear 1362 , and the third gear 1363 are different.

[0149] By adjusting the gear size (i.e., the number of teeth and diameter), different gear ratios can be achieved. This flexibility allows designers to optimize system performance based on specific mechanical requirements and kinematic characteristics. For example, a larger gear can be used to drive a smaller gear to increase output speed, or a smaller gear can be used to drive a larger gear to increase output torque.

[0150] Different size gear combinations can achieve specific force and speed conversion in the system. For example, when a larger pushing force is needed to open the refrigerator 100 door, the gear train 136 can be designed to provide higher torque; while when a quick closing is needed, the gear ratio can be adjusted to increase the speed.

[0151] As shown in some embodiments, the power-assisted assembly 130 further comprises a housing 137 arranged on the door body 120, and the pulling member 131 is slidingly arranged in the housing 137. Figures 1 to 16

[0152] The above technical solution has the following advantages or beneficial effects: the housing 137 provides a protective shell for the power-assisted assembly 130, preventing dust, moisture and other external factors from affecting the internal components. The presence of the housing 137 also enhances the overall stability of the system, ensuring that the pulling member 131 maintains the correct trajectory during sliding.

[0153] The housing 137 integrates the various parts of the power-assisted assembly 130 into a compact unit. This design helps to save space, making it suitable for use in space-limited devices such as refrigerators 100, and makes the installation and maintenance of the power-assisted assembly 130 more convenient; and can prevent users from accidentally touching moving parts when operating the refrigerator 100 door, reducing potential safety risks.

[0154] In addition, the housing 137 can be coordinated with the appearance design of the refrigerator 100 door body 120, achieving an overall aesthetic and integrated visual effect.

[0155] In some embodiments, in order to better assemble the housing 137, the door body 120 has a receiving groove to accommodate the housing 137, when the power-assisted assembly 130 is switched from the retracted state to the extended state, both the pulling member 131 and the power-assisted member 132 extend out of the receiving groove, when the power-assisted assembly 130 is switched from the extended state to the retracted state, the power-assisted member 132 retracts into the receiving groove.

[0156] In other embodiments, the pulling member 131 is equivalent to a handle, located on the outside of the housing 137 and protruding from the housing 137, making it easy for users to pull.

[0157] In some embodiments, the power-assisted member 132 can be completely located inside the housing 137, and when the power-assisted assembly 130 is switched from the retracted state to the extended state, the power-assisted member 132 is located outside the housing 137.

[0158] In other embodiments, the power-assisted member 132 can be partially located inside the housing 137, and when the power-assisted assembly 130 is switched from the retracted state to the extended state, the power-assisted member 132 is completely located outside the housing 137.

[0159] ​In some embodiments, the shell 137 includes a mounting base 1371 disposed on the door body 120, a cover plate 1372 disposed on the mounting base 1371, and the pulling member 131 slidingly disposed on the cover plate 1372.

[0160] The technical solution has the following advantages or beneficial effects: by dividing the shell 137 into two parts, the mounting base 1371 and the cover plate 1372, a modular design is achieved. The mounting base 1371 is directly disposed on the door body 120, providing a stable foundation for the entire assistive assembly 130. This design ensures the stability of the assembly during use, reducing displacement caused by vibration or external forces. The cover plate 1372 covers the mounting base 1371, providing additional protection for the internal components, preventing dust, moisture, and other external factors from entering.

[0161] By slidingly disposing the pulling member 131 on the cover plate 1372, the cover plate 1372 can provide a precise motion guide path for the pulling member 131. This design ensures the linear motion of the pulling member 131, reducing deviation and friction.

[0162] In addition, the design of the cover plate 1372 allows users to easily maintain and replace the assembly. By simply removing the cover plate 1372, the internal components can be accessed, simplifying the maintenance process.

[0163] In some embodiments, the mounting base 1371 can be installed and fixed on the door body 120 by bolts or other means.

[0164] In some embodiments, the cover plate 1372 has an adjustment hole 13721 extending along the first direction, and the pulling member 131 has a sliding part 1313 sliding within the adjustment hole 13721.

[0165] The technical solution has the following advantages or beneficial effects: the design of the adjustment hole 13721 allows the sliding part 1313 to move within it, providing flexible adjustment capability for the pulling member 131. Through the cooperation of the adjustment hole 13721 and the sliding part 1313, the movement path of the pulling member 131 can be precisely controlled. This design ensures the linear motion of the pulling member 131 in the first direction, improving the motion accuracy and reliability of the system.

[0166] In some embodiments, the assistive assembly 130 further includes a moving member 138 slidingly disposed relative to the mounting base 1371, and the sliding part 1313 is a threaded fastener passing through the moving member 138 and the pulling member 131 to synchronize the movement of the moving member 138 and the pulling member 131.

[0167] The technical scheme has the advantages or beneficial effects that the sliding part 1313 is designed as a threaded fastener, which can connect the moving part 138 and the pulling part 131 together to ensure the stability between the moving part 138 and the pulling part 131 and prevent the relative displacement of the moving part 138 and the pulling part 131 during movement.

[0168] Further, through the threaded fastener, the user can conveniently adjust the positions of the moving part 138 and the pulling part 131 and lock the relative positions by tightening the thread. This design simplifies the adjustment process and improves the convenience of installation and maintenance.

[0169] In some embodiments, the moving part 138 is two, and the two moving parts 138 are arranged between the mounting seats 1371 and slide along the height direction of the cabinet 110.

[0170] Correspondingly, the transmission part 133 is also two, and the two transmission parts 133 are located on the two sides of the assisting part 132, which is designed to ensure the stability of movement.

[0171] The refrigerator provided by the embodiment of the application comprises a cabinet having a front side and a rear side; a door body movably connected to the cabinet; and an assisting assembly movably arranged on the door body, wherein the assisting assembly comprises a pulling part and an assisting part movably connected to the pulling part. The assisting assembly has an extended state and a retracted state which can be switched to each other. When the assisting assembly is switched from the retracted state to the extended state, the pulling part moves along a first direction to drive the assisting part to move along a second direction, and provides assistance for opening of the door body to make the door body in an open state. When the assisting assembly is switched from the extended state to the retracted state, the assisting part is configured to move along the first direction to drive the pulling part to move along the second direction to make the door body in a closed state. The first direction and the second direction are opposite, and the first direction is a direction in which the rear side of the cabinet points to the front side of the cabinet.

[0172] Through the design of the assisting assembly, the user can obtain additional thrust support when opening the refrigerator door. When the pulling part is pulled by the user, the assisting part can push open the door body to achieve the assisting effect. This design reduces the force required by the user to open the door, making it easier to open the refrigerator door, thereby achieving the opening of the door body with less force, which is especially suitable for users with less strength or in the case of a heavy refrigerator door. In addition, the moving direction of the assisting assembly is always consistent with the direction of the user's force, improving the user's comfort when opening the door, conforming to the user's usual opening behavior, and improving the overall user experience, especially in the case of frequent opening and closing of the door.

[0173] In addition, as Figures 1 to 16As shown, the embodiments of the present application also provide a refrigerator 100, comprising: a cabinet 110; a door body 120 movably connected to the cabinet 110; and a power assisting assembly 130 movably arranged on the door body 120, the power assisting assembly 130 is configured to extend out of the door body 120 and provide a pushing force to the door body 120 so that the door body 120 is in an open state; or the power assisting assembly 130 is configured to retract into the door body 120 so that the door body 120 is in a closed state.

[0174] The refrigerator provided by the embodiments of the present application can provide additional pushing force support for the user when opening the refrigerator door. When the pulling member is pulled by the user, the power assisting member can push the door body open to achieve the power assisting effect. This design reduces the force required by the user to open the door, making it easier to open the refrigerator door, thereby achieving the opening of the door body with less force, which is particularly suitable for users with less strength or in the case of a heavy refrigerator door. In addition, the moving direction of the power assisting assembly is always consistent with the direction of the user's force, improving the user's comfort when opening the door, conforming to the user's usual opening behavior, and improving the overall user experience, especially in the case of frequent opening and closing of the door.
