[0076] Figure 1 This is a schematic diagram of the structure of a refrigerator provided by an embodiment of the utility model. Figure 2 for Figure 1 The local enlarged view of point I in the middle, Figure 3 This is a schematic diagram of the structure of the lock assembly in the refrigerator provided by the embodiment of the utility model. Figure 4 A partial cross-sectional view of a lock assembly in a refrigerator provided by an embodiment of the present invention.

[0077] like Figures 1 to 4 As shown, the embodiment of the present invention provides a refrigerator 100, comprising:

[0078] Box 110;

[0079] The door body 120 is movably connected to the box body 110;

[0080] The locking assembly 130 includes:

[0081] A first locking member 131 , the first locking member 131 is rotatably mounted on the box body 110 , and has a first locking portion 1311 ;

[0082] The second locking member 132 is movably disposed on the door body 120 , and the structure of the second locking member 132 matches the structure of the first locking portion 1311 .

[0083] The locking assembly 130 has a locking state and an unlocking state that can be switched between each other. When the locking assembly 130 switches from the unlocking state to the locking state, the first locking component 131 is configured to rotate along the first direction to squeeze the second locking component 132 to move along the second direction. When the first locking component 131 rotates into the door body 120, the second locking component 132 disengages from the squeezing of the first locking component 131 and moves along the third direction, and is locked with the first locking portion 1311.

[0084] When the locking assembly 130 switches from a locked state to an unlocked state, the second locking member 132 is configured to move along the second direction, and the first locking member 131 is configured to rotate along the fourth direction to disengage the first locking portion 1311 from the second locking member 132, wherein the second direction is opposite to the third direction, and the first direction is opposite to the fourth direction.

[0085] By setting the lock assembly 130, the refrigerator 100 adds a locked state and an unlocked state, and can switch between the two states. The door body 120 cannot be opened easily, which effectively prevents children from opening the door body 120 at will, reduces potential safety hazards, improves the overall safety of the refrigerator 100, prevents children from accidentally eating items in the refrigerator 100 or prevents power loss caused by opening the door body 120 for a long time, reduces the energy consumption of the refrigerator 100, and saves electricity; in addition, it does not affect the normal use of the user, improves the safety of the use of the refrigerator 100, and has a strong practical effect.

[0086] It should be noted that each structure is described in detail below.

[0087] [Box 110]

[0088] refer to Figure 1 The refrigerator 100 of the present invention may include a housing 110 and a door 120. The housing 110 may be configured with a refrigeration compartment. The refrigeration compartment has an opening for storing food and other items. The number of refrigeration compartments may be one or more. When there are multiple refrigeration compartments, the multiple refrigeration compartments may be divided into a refrigerator compartment, a freezer compartment, or a temperature-changing chamber, etc.

[0089] For example, the housing 110 may include an outer shell and an inner liner. The outer shell defines the exterior of the refrigerator 100. The inner liner may be disposed within and connected to the outer shell. The inner liner may be recessed inward to form a refrigeration compartment. An insulation layer may be placed between the outer shell and the inner liner to insulate the refrigeration compartment, thereby reducing energy consumption of the refrigerator 100.

[0090] [Door 120]

[0091] It should be noted that the door 120 can be connected to the housing 110 to open or close the refrigeration compartment. One door 120 can be provided for each refrigeration compartment. Alternatively, two doors 120 can be provided for each refrigeration compartment.

[0092] For example, the door body 120 can be rotated relative to the box body 110, or can be pushed and pulled, without further limitation.

[0093] [Lock assembly 130]

[0094] The above technical solution has the following advantages or beneficial effects: the refrigerator 100 of the present invention can switch between a locked state and an unlocked state through the setting of the lock assembly 130. When in the locked state, it can prevent children from opening the refrigerator 100, resulting in a waste of electricity, and even prevent children from entering the refrigerator 100, causing a hidden danger to personal safety.

[0095] When the latch assembly 130 is switched from the unlocked state to the locked state, the user rotates the first latch member 131, and the first latch member 131 rotates relative to the box body 110 along the first direction and gradually approaches the door body 120. When contacting the door body 120, the second latch member 132 located on the door body 120 is contacted and squeezed. The second latch member 132 moves along the second direction under the squeezing of the first latch member 131. At this time, the second latch member 132 moves and hides in the door body 120 until the first latch member 131 completely enters the door body 120. The second latch member 132 is disengaged from the squeezing of the first latch member 131 and moves along the third direction opposite to the second direction and returns to the initial position. At this time, the second latch member 132 is locked with the first latch portion 1311, so that the first latch portion 1311 is locked in the door body 120, and finally is in the locked state, which can prevent children from opening it.

[0096] It should be noted that when the lock assembly 130 switches from the locked state to the unlocked state, the user pulls the second lock member 132, and the second lock member 132 moves along the second direction. At this time, the second lock member 132 moves again and is hidden in the door body 120. The first lock member 131 no longer has the lock of the second lock member 132, and rotates along the fourth direction opposite to the first direction, and finally rotates out of the door body 120, and finally reaches the unlocked state, which is convenient for users to open and use normally.

[0097] Here, X represents the first direction, and Y represents the fourth direction.

[0098] Through the above-mentioned setting, that is, through the setting of the lock assembly 130, the refrigerator 100 adds a locked state and an unlocked state, and can switch between the two states. The door body 120 cannot be opened easily, which effectively avoids the situation where children open the door body 120 at will, reduces potential safety hazards, improves the overall safety of the refrigerator 100, prevents children from accidentally eating items in the refrigerator 100 or prevents power loss due to opening the door body 120 for a long time, reduces the energy consumption of the refrigerator 100, and saves electricity; in addition, it does not affect the normal use of the user, improves the safety of the use of the refrigerator 100, and has a strong practical effect.

[0099] Figure 5 This is a schematic diagram of the assembly of the first locking member and the first locking frame in the first state of the refrigerator provided by the embodiment of the utility model. Figure 6 This is a schematic diagram of the assembly of the first locking member and the first locking frame in the second state in the refrigerator provided by an embodiment of the present utility model.

[0100] like Figures 1 to 6 As shown, in some embodiments, the first locking portion 1311 is located at the edge of the first locking member 131 .

[0101] There are at least two first locking portions 1311 and at least two second locking members 132 . The positions of the first locking portions 1311 and the second locking members 132 match each other. The two first locking portions 1311 are located at opposite ends of the first locking member 131 along the second direction.

[0102] The above technical solution has the following advantages or beneficial effects: since there are at least two first locking parts 1311 and second locking parts 132, and their positions match each other, this multi-point locking design can provide higher stability and firmness, ensuring that the door body 120 will not be easily opened in the locked state, increasing the difficulty of the door body 120 being accidentally opened, and further improving the safety of use of the refrigerator 100, especially preventing children from opening the door body 120 at will.

[0103] The two first locking portions 1311 are located at opposite ends of the first locking member 131 along the second direction. This symmetrical distribution design enables the locking assembly 130 to be evenly stressed when locked, reducing deformation or damage that may be caused by single-point stress. Since the locking assembly 130 is evenly stressed, local wear and stress concentration are reduced, thereby extending the service life of the locking assembly 130.

[0104] It should be noted that there are two second locking members 132 , which are disposed on both sides of the door body 120 along the second direction.

[0105] When the lock assembly 130 switches from the unlocked state to the locked state, the two second lock members 132 move away from each other under the pressure of the first lock member 131 until they move and hide inside the door body 120. At the moment when the first lock member 131 completely enters the door body 120, the two second lock members 132 break away from the pressure of the first lock member 131 and move toward each other.

[0106] like Figures 1 to 6 As shown, in some embodiments, the first locking member 131 is a rotating block.

[0107] The locking assembly 130 further includes a first rotating shaft 133 rotatably disposed on the housing 110 , and the first locking member 131 rotates relative to the housing 110 via the first rotating shaft 133 ; and / or the first locking portion 1311 is a groove.

[0108] The above technical solution has the following advantages or beneficial effects: since the first locking member 131 is a rotating block and rotates relative to the box body 110 through the first rotating shaft 133, this design allows the first locking member 131 to be flexibly locked and unlocked. The design of the rotating block and the groove reduces the complexity of the first locking member 131, is easy to manufacture and install, reduces production costs and maintenance difficulty, and users can conveniently operate the locking assembly 130.

[0109] The first locking portion 1311 is a groove, which can provide a stable locking mechanism. When the first locking member 131 is rotated to the locked position, the second locking member 132 can be firmly embedded in the corresponding groove, ensuring that the door body 120 will not be easily opened in the locked state.

[0110] In some embodiments, the first locking portion 1311 is recessed into the first locking member 131 , and the first locking portion 1311 is provided with a notch facing upward and toward the first locking member 131 .

[0111] In addition, since the first locking member 131 is rotated by the first rotating shaft 133 , the wear caused by direct sliding friction is reduced, thereby extending the service life of the locking assembly 130 .

[0112] like Figures 1 to 6 As shown, in some embodiments, the locking assembly 130 further includes a first locking frame 134 and a second locking frame 135 . The first locking frame 134 is disposed on the box body 110 , and the second locking frame 135 is disposed on the door body 120 .

[0113] The first locking frame 134 and the second locking frame 135 are connected to form an accommodating cavity. When the locking assembly 130 switches from the unlocked state to the locked state, the first locking member 131 is accommodated in the accommodating cavity.

[0114] When the locking assembly 130 switches from the locked state to the unlocked state, at least a portion of the first locking member 131 is located outside the accommodating cavity.

[0115] The above technical solution has the following advantages or beneficial effects: through the connection design of the first lock frame 134 and the second lock frame 135, a basis for installation is provided for the first lock member 131 and the second lock member 132, and space is provided for the rotation of the first lock member 131. The user can conveniently operate the lock assembly 130 to achieve locking and unlocking of the door body 120, thereby simplifying the use process.

[0116] The first locking frame 134 and the second locking frame 135 are connected and form a accommodating cavity. When the locking assembly 130 is in the locked state, the first locking member 131 is completely accommodated in the accommodating cavity, providing a stable locking effect, ensuring that the door body 120 will not be easily opened in the locked state. The first locking member 131 is completely accommodated in the accommodating cavity in the locked state, making the appearance more beautiful and tidy without affecting the overall design of the refrigerator 100.

[0117] When the locking assembly 130 is in the locked state, the first locking member 131 is completely accommodated in the accommodating cavity, preventing a child from easily opening the door body 120 , thereby improving the safety of the refrigerator 100 .

[0118] In some embodiments, the first locking frame 134 can be detachably or fixedly mounted on the box body 110 , such as by screw mounting, snap mounting, or welding, etc., without further limitation herein.

[0119] In some embodiments, the second locking frame 135 can be set on the door body 120 in a detachable manner or a fixed manner, such as screw installation, snap installation or welding, etc., without further limitation here.

[0120] Specifically, the first end of the first locking member 131 rotates relative to the first locking frame 134 through the first rotating shaft 133, and the first end of the first locking member 131 is always in the accommodating cavity. When rotating along the first direction, the second end of the first locking member 131 gradually approaches the accommodating cavity until it enters the accommodating cavity to lock with the second locking member 132 to complete the locking state of the refrigerator 100.

[0121] When the locking assembly 130 switches from the locked state to the unlocked state, the second end of the first locking member 131 rotates along the fourth direction, that is, the second end of the first locking member 131 rotates from inside the accommodating cavity to outside the accommodating cavity. At this time, the second end of the first locking member 131 is away from the door body 120, and the refrigerator 100 is in the unlocked state.

[0122] In some embodiments, the first locking frame 134 can be made of a metal material to provide the first locking frame 134 with better structural strength, thereby improving the durability and reliability of the first locking frame 134. Of course, the first locking frame 134 can also be made of a polymer material to provide the first locking frame 134 with better structural strength while being relatively light, thereby reducing the weight of the locking assembly 130.

[0123] Of course, the structure and material of the second locking frame 135 may refer to the first locking frame 134 , and no further restrictions are imposed herein.

[0124] In some embodiments, the box body 110 defines a first embedding groove, the first locking frame 134 is disposed in the first embedding groove, the door body 120 defines a second embedding groove, the second locking frame 135 is disposed in the second embedding groove.

[0125] The above technical solution has the following advantages or beneficial effects: the first locking frame 134 is embedded in the first embedding groove of the cabinet 110, and the second locking frame 135 is embedded in the second embedding groove of the door 120, thereby making the connection between the first locking frame 134 and the second locking frame 135 and the cabinet 110 and the door 120 respectively more secure, thereby enhancing the stability of the overall structure. In addition, the locking assembly 130 is more concealed in appearance and does not affect the overall aesthetic design of the refrigerator 100.

[0126] The design of the first embedding groove and the second embedding groove ensures that the first lock frame 134 has a fixed position in the box body 110, and the second lock frame 135 has a fixed position in the door body 120, reducing the possible misoperation of the lock assembly 130 during use, and improving the safety and reliability of use; making the installation of the first lock frame 134 and the second lock frame 135 easier, ensuring that the first lock frame 134 and the second lock frame 135 can be accurately positioned, simplifying the installation process, and improving production efficiency.

[0127] In some embodiments, the second locking member 132 includes a locking hook 1321 , a second elastic member 1322 and a toggle block 1323 , and the second elastic member 1322 is located between the locking hook 1321 and the toggle block 1323 .

[0128] When the lock hook 1321 is pressed against the first locking member 131 , the toggle block 1323 is driven by the lock hook 1321 to move along the second direction, so that the toggle block 1323 is located outside the second locking frame 135 .

[0129] When the lock hook 1321 is released from the first locking member 131 and pressed, the toggle block 1323 is driven by the lock hook 1321 to move along the third direction, so that the toggle block 1323 is located inside the second locking frame 135 .

[0130] The above technical solution has the following advantages or beneficial effects: When the first locking member 131 squeezes the lock hook 1321, the toggle block 1323, driven by the lock hook 1321, moves in the second direction, positioning the toggle block 1323 outside the second lock frame 135, facilitating rotation of the first locking member 131 into the accommodating cavity. When the lock hook 1321 is released from the squeezing of the first locking member 131, the toggle block 1323, driven by the lock hook 1321, moves in the third direction, positioning the toggle block 1323 inside the second lock frame 135, achieving automatic locking. This automatic locking and unlocking function simplifies user operation and improves usability.

[0131] The second elastic member 1322 is located between the lock hook 1321 and the toggle block 1323, providing a stable elastic force so that the lock hook 1321 can move smoothly during the locking and unlocking process, thereby ensuring the stability and reliability of locking and unlocking.

[0132] The second elastic member 1322 provides a buffering effect between the lock hook 1321 and the toggle block 1323, reducing direct friction between the lock hook 1321 and the toggle block 1323 during movement, thereby reducing wear and extending the service life of the lock assembly 130. The combined design of the lock hook 1321, the second elastic member 1322, and the toggle block 1323 makes the lock assembly 130 more compact, saving space, while ensuring the coordinated operation of the various components and improving the rationality and aesthetics of the overall design.

[0133] In addition, the setting of the toggle block 1323 is convenient for the user to operate, such as pulling by the user, that is, it is convenient for the user to apply force.

[0134] It should be noted that when the locking assembly 130 switches from the locked state to the unlocked state, the user pulls the toggle block 1323 and then pulls the lock hook 1321, so that the lock hook 1321 moves along the second direction.

[0135] Specifically, the two second locking members 132 move away from each other, and at this time the locking hook 1321 of the second locking member 132 disengages from the lock on the first locking portion 1311. At this time, the first locking member 131 rotates along the fourth direction under the elastic force of the first elastic member 141 until it disengages from the second locking frame 135. At this time, the first locking member 131 and the second locking member 132 are in an unlocked state, and the locking hook 1321 returns to its initial position under the elastic force of the second elastic member 1322, that is, the two second locking members 132 move toward each other and protrude from the second locking frame 135.

[0136] In some embodiments, the second elastic member 1322 is a compression spring.

[0137] The second locking member 132 further includes a guide post 1324 . The guide post 1324 is disposed between the lock hook 1321 and the toggle block 1323 . The second elastic member 1322 is sleeved around the outer circumference of the guide post 1324 .

[0138] The above technical solution has the following advantages or beneficial effects: the compression spring as the second elastic member 1322 can provide stable and uniform elastic force, so that the lock hook 1321 and the toggle block 1323 can move smoothly during the locking and unlocking process, ensuring the stability and reliability of locking and unlocking.

[0139] Guide post 1324 is positioned between lock hook 1321 and toggle block 1323, and second elastic member 1322 is sleeved around the periphery of guide post 1324. This design ensures precise guidance of lock hook 1321 and toggle block 1323 during movement, preventing deviation and jamming, and improving the efficiency and reliability of latch assembly 130. Guide post 1324 provides a movement path for lock hook 1321 and toggle block 1323, reducing direct friction and wear, thereby extending the service life of latch assembly 130. The use of second elastic member 1322 also provides a cushioning effect, further reducing wear.

[0140] In addition, in order to meet the movement of the second locking member 132, in some embodiments, a slide groove 1351 and a slider 1352 are set on the second locking frame 135, wherein the slider 1352 is connected to the lock hook 1321, and the lock hook 1321 is connected to the toggle block 1323 through the guide column 1324. When the slider 1352 moves in the slide groove 1351, it drives the lock hook 1321, the guide column 1324 and the toggle block 1323 to move synchronously.

[0141] It should be noted that, in some embodiments, the lock hook 1321 and the slider 1352 are connected in an integrated manner, and in other embodiments, the lock hook 1321 and the slider 1352 can also be connected in other manners. As long as the connection method can fix the lock hook 1321 and the slider 1352, the purpose of this embodiment can be achieved. Here, there is no restriction on the connection method between the lock hook 1321 and the slider 1352.

[0142] In some embodiments, the locking hook 1321 has an arcuate abutment portion. When the first locking member 131 is configured to rotate along the first direction, the end of the first locking member 131 is pressed against the arcuate abutment portion to move the second locking member 132 along the second direction.

[0143] The above technical solution has the following advantages or beneficial effects: the arc-shaped abutting portion not only provides smooth force transmission and automatic locking and unlocking functions, but also reduces wear and tear, and improves locking stability and safety in use.

[0144] The design of the arc-shaped abutting portion enables the end portion of the first locking member 131 to smoothly contact and press the locking hook 1321 when the first locking member 131 rotates along the first direction.

[0145] This smooth force transmission reduces friction and resistance, improving the operational efficiency and reliability of the latch assembly 130. When the end of the first latch member 131 presses against the curved abutment, the lock hook 1321, under the action of the force, moves in the second direction, causing the second latch member 132 to lock or unlock. This design enables automatic locking and unlocking, simplifies user operation, and improves ease of use. It ensures that the lock hook 1321 can move stably when pressed by the first latch member 131, enhancing the stability and reliability of the locking and unlocking process and ensuring that the door body 120 cannot be easily opened when locked.

[0147] Figure 7 This is a schematic diagram of the assembly of the second locking member and the second locking frame in the refrigerator provided by the embodiment of the utility model. Figure 8 This is a schematic diagram of the assembly of the second locking member and the second locking frame in the first state of the refrigerator provided by the embodiment of the utility model. Figure 9 for Figure 8 A partial enlarged view of point II in the middle. Figure 10 This is a schematic diagram of the assembly of the second locking member and the second locking frame in the second state in the refrigerator provided by an embodiment of the present invention.

[0148] like Figures 3 to 10As shown, in some embodiments, the refrigerator 100 further includes an elastic component 140, the elastic component 140 includes a first elastic member 141, the first end of the first elastic member 141 is connected to the second locking frame 135, and the second end of the first elastic member 141 extends toward the middle of the accommodating cavity.

[0149] When the first locking member 131 rotates into the accommodating cavity, the first locking member 131 abuts between the second end of the first elastic member 141 and the second locking member 132 .

[0150] When the second locking member 132 is configured to move along the second direction, the first locking member 131 rotates along the fourth direction under the elastic force of the first elastic member 141 , so that at least a portion of the first locking member 131 is located outside the accommodating cavity.

[0151] The above technical solution has the following advantages or beneficial effects: the first elastic member 141 provides an elastic force, so that when the second locking member 132 moves in the second direction, the first locking member 131 can automatically return to its original position under the action of the elastic force and rotate in the fourth direction, so that at least a portion of the first locking member 131 is located outside the accommodating cavity. This automatic return function simplifies user operation and improves convenience.

[0152] In addition, the first elastic member 141 provides a stable elastic force during the locking and unlocking process, so that the first locking member 131 can be reliably fixed when it is rotated into the accommodating cavity, and can be smoothly reset when it is unlocked, ensuring the stability and reliability of the locking and unlocking process.

[0153] The first elastic member 141 provides a buffering effect during the rotation of the first locking member 131 , reducing direct friction between the first locking member 131 and other components, thereby reducing wear and tear and extending the service life of the locking assembly 130 .

[0154] When the locking assembly 130 is in the locked state, the first locking member 131 is squeezed between the second end of the first elastic member 141 and the second locking member 132, providing additional locking force, enhancing the locking effect, and ensuring that the door body 120 will not be easily opened in the locked state.

[0155] In some embodiments, the first elastic member 141 can be detachably or fixedly arranged on the second locking frame 135 , such as by screw installation, snap installation, or welding, etc., without further limitation here.

[0156] In some embodiments, the first elastic member 141 is a spring.

[0157] The elastic component 140 also includes a rotating plate 143 and a second rotating shaft 142. The second rotating shaft 142 is rotatably set on the second locking frame 135. The rotating plate 143 is rotatably set in the accommodating cavity through the second rotating shaft 142. The first elastic member 141 is located between the second locking frame 135 and the rotating plate 143.

[0158] The above technical solution has the following advantages or beneficial effects: the first elastic member 141 is a spring sheet with good elasticity and restoring force, and the setting of the rotating plate 143 increases the uniformity of the elastic force distribution acting on the first locking member 131, making it more stable during the resetting process.

[0159] The rotating plate 143 is rotatably disposed within the accommodating cavity via the second rotating shaft 142. In conjunction with the elastic force of the first elastic member 141, when the second locking member 132 moves in the second direction, the rotating plate 143 automatically resets under the elastic force, driving the first locking member 131 to rotate in the fourth direction, so that at least a portion of the first locking member 131 is located outside the accommodating cavity. This automatic reset function simplifies user operation and improves usability.

[0160] The first elastic member 141 provides a buffering effect during the rotation of the first locking member 131, reducing direct friction between the first locking member 131 and other components, thereby reducing wear and extending the service life of the locking assembly 130. The design of the rotating plate 143 and the second rotating shaft 142 makes the locking assembly 130 more compact, saving space, while ensuring the coordinated operation of various components and improving the rationality and aesthetics of the overall design.

[0161] In some embodiments, the first elastic member 141 may be a V-shaped spring piece, which has excellent elastic properties and can quickly return to its original shape after being subjected to force. This makes it very effective in applications that require frequent deformation and recovery.

[0162] In addition, the V-shaped spring can effectively absorb and buffer external shocks and vibrations, thereby protecting the first locking member 131 and other mechanical components from damage.

[0163] The refrigerator provided by the embodiment of the utility model includes: a box body; a door body, movably connected to the box body; a lock assembly, the lock assembly including a first lock piece and a second lock piece, the first lock piece being rotatably arranged on the box body, the first lock piece having a first lock portion, the second lock piece being movably arranged on the door body, and the structure of the second lock piece matching the structure of the first lock portion; the lock assembly has a lock state and an unlock state that can be switched with each other, when the lock assembly switches from the unlock state to the lock state, the first lock piece is configured to rotate along a first direction to squeeze the second lock piece to move along a second direction, when the first lock piece rotates into the door body, the second lock piece is disengaged from the squeezing of the first lock piece and moves along a third direction, and is locked with the first lock portion; when the lock assembly switches from the lock state to the unlock state, the second lock piece is configured to move along the second direction, and the first lock piece is configured to rotate along a fourth direction to disengage the first lock portion from the second lock piece; wherein the second direction is opposite to the third direction, and the first direction is opposite to the fourth direction.

[0164] By setting the lock assembly, the refrigerator has added a locked state and an unlocked state, and can switch between the two states. The door cannot be opened easily, which effectively prevents children from opening the door at will, reduces potential safety hazards, improves the overall safety of the refrigerator, prevents children from accidentally eating items in the refrigerator or prevents power loss caused by opening the door for a long time, reduces the energy consumption of the refrigerator, and saves electricity; in addition, it does not affect the normal use of the user, improves the safety of the refrigerator, and has a strong practical effect.
