[0002] When using a refrigerator, the inner door is usually locked to the inner liner using a latching mechanism. This involves a latch on the door and a matching slot on the inner liner; the latch engages with the slot to lock the door. However, when using this mechanism, the latch must be aligned with the slot when closing the door; otherwise, it may not lock properly, making the operation difficult and inconvenient. Utility Model Content

[0003] In order to overcome at least one of the defects of the prior art, one of the objectives of this utility model is to provide a door locking component, which can be guided to rotate and lock with the locking groove when force is applied, making locking or unlocking operations more convenient.

[0004] The second objective of this utility model is to provide a refrigerator in which the inner liner door can be locked or unlocked by a locking component, making operation convenient.

[0005] One of the objectives of this utility model is achieved through the following technical solution: A door locking assembly, comprising: A locking seat, wherein the locking seat is provided with a locking groove, and the inner wall of the locking groove is provided with a first guide part and a first locking part; A locking mechanism, comprising a locking element and a first elastic component, wherein the locking element has a force-receiving end and a locking end. The locking end is provided with a second guide and a second locking part. The locking end is used to move closer to the locking groove when the force-bearing end is subjected to force. The second guide slides with the first guide and guides the locking end to rotate. The second locking part is used to lock or unlock with the first locking part after the locking end rotates. The first elastic member is provided in the locking groove and is used to provide an elastic stress to drive the locking end away from the locking groove.

[0006] Furthermore, the locking groove has an opening, and the end wall of the opening is provided with a first limiting notch, which forms the first locking part; the second locking part is a limiting block provided on the locking end, which corresponds to the first limiting notch and is used to lock the locking end by offsetting from the first limiting notch when the locking end rotates.

[0007] Furthermore, the first guide portion is a guide block disposed in the locking groove, and the guide block has a guide surface; the second guide portion is a first guide slope disposed on the limiting block, and the first guide slope slides in cooperation with the guide surface to guide the locking end to rotate.

[0008] Furthermore, the guiding surface is a second guiding inclined surface provided on the guiding block, and the second guiding inclined surface slides in conjunction with the first guiding inclined surface.

[0009] Furthermore, the limiting block is provided with a third guide slope, the third guide slope being inclined in the opposite direction to the first guide slope; the guide block is provided with a fourth guide slope, the fourth guide slope being inclined in the opposite direction to the second guide slope, and slidingly engaging with the third guide slope to guide the locking end to rotate.

[0010] Furthermore, the locking end is provided with a plurality of limiting blocks, which are distributed at intervals along the circumference of the locking end; a plurality of guide blocks are provided, which are distributed at intervals along the circumference of the locking groove and are respectively configured to correspond to the plurality of limiting blocks; a plurality of first limiting notches are provided, which are distributed at intervals along the circumference of the locking groove.

[0011] Furthermore, the locking mechanism also includes a second elastic component, one end of which passes through the force-bearing end and is used to provide an elastic stress to drive the locking end to move closer to the locking groove.

[0012] Furthermore, the force-receiving end is provided with a limiting ring, which extends circumferentially along the force-receiving end.

[0013] The technical solution adopted for the second objective of this utility model is: A refrigerator includes an inner liner, a door, and a locking assembly; the locking seat is detachably connected to the inner liner, and the locking mechanism is connected to the door.

[0014] Furthermore, the inner liner is provided with a first through-hole, which is connected to the locking groove; the first locking part is provided on the end wall of the first through-hole; the compartment door is provided with a second through-hole, which is correspondingly provided to the first through-hole and is connected to it.

[0025] The technical solution of this utility model will be further described below with reference to the embodiments and accompanying drawings.

[0026] Example 1, See Figure 1 and Figure 8 This utility model discloses a door locking assembly, including: a locking seat 10 and a locking mechanism 20. The locking seat 10 is provided with a locking groove 11, and the inner wall of the locking groove 11 is provided with a first guide part 12 and a first locking part. The locking mechanism 20 includes a locking member 21 and a first elastic member 22. The locking member 21 has a force-receiving end 211 and a locking end 212. The locking end 212 is provided with a second guide part and a second locking part 2121. When the force-receiving end 211 is subjected to force, the locking end 212 moves closer to the locking groove 11. The second guide part is slidably engaged with the first guide part 12 and is used to guide the locking end 212 to rotate. After the locking end 212 rotates, the second locking part 2121 locks or unlocks with the first locking part. The first elastic member 22 is provided in the locking groove 11 and can provide an elastic stress to drive the locking end 212 away from the locking groove 11.

[0027] Based on the above structure, the first guide part 12 is a block-shaped or columnar protrusion provided on the inner wall of the locking groove 11, the first locking part is a notch or slot provided at the opening end wall of the locking groove 11, the second guide part is an inclined surface or arc surface formed on the locking end 212, and the second locking part 2121 is a block-shaped or columnar protrusion provided on the locking end 212 that matches the first locking part (such as a notch). The following is an example of the above structure: When the locking component is in the unlocked state, the second locking part 2121 corresponds to the latch (i.e., the first locking part), and the locking end 212 can pass through the latch and enter the locking groove 11 when force is applied. When performing the locking action, the user applies external force to the force-receiving end 211, and the locking end 212 moves towards the locking groove 11 under the drive of the external force. Since the second locking part 2121 corresponds to the latch, the locking end 212 can smoothly pass through the latch and extend into the locking groove 11. During this process, the first elastic component 22 in the locking groove 11 is compressed, accumulating elastic potential energy for the subsequent unlocking action. As the locking end 212 continues to move towards the bottom of the locking groove 11, until the inclined surface or arc surface (second guide part) on the locking end 212 abuts against the first guide part 12. At this point, when the inclined or curved surface (second guide portion) contacts the outer peripheral wall of the first guide portion 12, a non-perpendicular contact interface is formed. This non-perpendicular contact surface prevents the locking end 212 from moving linearly as it continues to be forced deeper into the locking groove 11, causing it to rotate and dislocate the second locking portion 2121 from the latch (first locking portion). As a result, because the second locking portion 2121 does not correspond to the latch, it cannot exit the latch, thus firmly locking the locking end 212 within the locking groove 11, completing the locking state.

[0028] Similarly, when unlocking is required, pressing the force-receiving end 211 again causes the locking end 212 to overcome part of the elastic force of the first elastic component 22 under the action of external thrust, moving towards the bottom of the locking groove 11. This causes the inclined or curved surface (second guide portion) on the locking end 212 to slide and engage with the outer periphery of the first guide portion 12 again. At this time, the above-mentioned process of structural engagement, force application, and motion transformation occurs in reverse. Under this sliding engagement, the locking end 212 rotates again until the second locking portion 2121 aligns with the latch (first locking portion) again. At this time, the first elastic component 22 releases the previously accumulated elastic potential energy, generating an elastic force to eject the locking end 212 from the locking groove 11, thus restoring the locking member 21 to the unlocked state.

[0029] It should be noted that when the second guide is an inclined surface, there can be two second guides with opposite inclination directions, so that they can cooperate with the first guide 12 in the opposite direction during the unlocking process, guiding the locking end 212 to rotate in the opposite direction; of course, if only one second guide is provided, during unlocking, a force for reverse rotation can be applied to the force receiving end 211, and the force receiving end 211 can be pressed, so that it rotates in the opposite direction synchronously during the pressing process, until the second locking part 2121 and the bayonet are aligned again.

[0030] Alternatively, the first locking part can be a ring-shaped wedge-shaped tooth (one side of the tooth surface is inclined and the other side is vertical) machined on the inner wall of the locking groove 11, while the second locking part 2121 is a radially retractable ring retainer on the locking end 212, with matching wedge-shaped teeth on its inner surface. When the second locking part 2121 is inserted into the locking groove 11, the retainer is compressed and contracted until the first guide part 12 and the second guide part slide into contact with the locking end 212 and rotate, causing the wedge-shaped teeth to engage. At this time, the retainer springs back and locks; when rotated in the opposite direction to the corresponding tooth groove, it unlocks, thus achieving the same effect.

[0031] Specifically, when the locking component of this embodiment is applied to a refrigerator or cabinet with a door, the locking seat 10 can be connected to the cabinet, and the door of the cabinet can be connected to the locking mechanism 20. When locking the door, simply press the force-receiving end 211 of the locking member 21, and the locking end 212 will extend into the locking groove 11. During this process, the second guide part on the locking end 212 and the first guide part 12 in the locking groove 11 automatically engage and slide, like gears meshing, guiding the locking end 212 to rotate until the first locking part and the second locking part 2121 lock, completing the door locking. When unlocking, press the force-receiving end 211 again, and the locking end 212 will rotate, causing the first and second locking parts 2121 to unlock and separate. At this time, the built-in first elastic member 22 releases its elastic force, ejecting the locking end 212 from the locking groove 11, and the door opens accordingly.

[0032] Thus, when closing the door, even if it is not perfectly aligned, as long as the locking part 21 approaches the locking groove 11, the first guide part 12 and the second guide part will automatically slide and engage, guiding the locking end 212 to rotate to lock the second locking part 2121 with the first locking part. Locking or unlocking can be completed without manually calibrating the angle. The entire operation only requires a simple press, making it convenient to operate.

[0033] It should be noted that the locking member 21 in this embodiment can be a locking rod-shaped or block-shaped structure, such as a locking rod or a locking block. A second guide portion is formed by setting a slope or arc surface at the bottom, and a block-shaped or column-shaped structure is set on the outer periphery to form a second locking portion 2121. Of course, when the second guide portion is a slope or arc surface, it can also be directly formed on the second locking portion 2121. Similarly, when the locking end 212 extends into the locking groove 11, it can slide and cooperate with the first guide portion 12 to guide the locking end 212 to rotate.

[0034] Alternatively, the first elastic component 22 can be an existing spring, elastic rubber column, or elastic sheet, which can be installed at the bottom of the locking groove 11 by welding or gluing.

[0035] Furthermore, the locking groove 11 has an opening, and the end wall of the opening is provided with a first limiting notch 311. The limiting notch is formed as a first locking part, and the second locking part 2121 is a limiting block provided on the locking end 212. The limiting block corresponds to the first limiting notch 311 and is used to offset from the first limiting notch 311 when the locking end 212 rotates so that the locking end 212 is locked.

[0036] Preferably, in this embodiment, the first locking part is a first limiting notch 311 formed at the opening of the locking groove 11, while the second locking part 2121 is a limiting block provided on the locking end 212. When the locking end 212 is not rotated, the limiting block is aligned with the first limiting notch 311 (unlocked state), and the locking end 212 can freely pass through the opening and enter and exit the locking groove 11. After the locking end 212 rotates, the limiting block rotates with the locking end 212 at a certain angle and abuts against and is offset from the edge wall of the limiting notch, forming a mechanical block (locked state), preventing the locking end 212 from exiting. The misalignment and blocking by the limiting block and the limiting notch is triggered by a clear rotation action, rather than a simple insertion or squeezing, which can reduce unlocking caused by accidental factors such as vibration and accidental contact, and improve structural stability.

[0037] It should be noted that the limiting notch can be designed as a polygon (such as a rectangle or trapezoid) or an arc, and the shape of the limiting block can match it to achieve unidirectional or multidirectional locking (such as locking that only allows clockwise rotation) to meet different application requirements.

[0038] Furthermore, the first guide part 12 is a guide block provided in the locking groove 11, and the guide block has a guide surface; the second guide part is a first guide inclined surface 21211 provided on the limiting block, and the first guide inclined surface 21211 slides with the guide surface to guide the locking end 212 to rotate.

[0039] Specifically, the guide surface can be an inclined surface set on the outer periphery of the guide block. When the locking end 212 is inserted into the locking groove 11 under the action of external force, the first guide inclined surface 21211 on the limit block slides along the inclined surface of the guide block. Due to the inclination angle of the inclined surface, the limit block generates a tangential component force when sliding, which pushes the locking end 212 to rotate in a predetermined direction (such as clockwise or counterclockwise) until the locking end 212 rotates until the limit block and the limit notch are completely misaligned, forming a locked state; similarly, the same applies when unlocking.

[0040] Of course, the guide surface can also be an arc surface set on the outer periphery of the guide block. When the locking end 212 extends into the locking groove 11 until the first guide inclined surface 21211 contacts the point on the arc surface, the component force of the contact point along the tangent direction of the arc surface drives the locking end 212 to rotate; and as the contact point continues to slide along the arc surface, the direction of the tangential component force changes with the tangent angle of the arc surface, and the guide locking end 212 eventually rotates until the limit block and the notch are misaligned, and it is in a locked state; similarly, unlocking is also the same.

[0041] Preferably, the guiding surface is a second guiding inclined surface 121 provided on the guiding block, and the second guiding inclined surface 121 slides in engagement with the first guiding inclined surface 21211. The inclination angles of the two inclined surfaces form a "geometric constraint," ensuring that the limiting block (which rotates with the locking end 212) can only slide along the direction of the guiding block's inclined surface, thereby forcing the locking end 212 to rotate along a predetermined trajectory (such as clockwise or counterclockwise). For example, if the inclination direction of the second guiding inclined surface 121 is right-high and left-low, when the first guiding inclined surface 21211 is in contact with it, the locking end 212 can only rotate to the upper right, preventing arbitrary wobbling or reverse rotation. Simultaneously, the sliding characteristics of the inclined surfaces automatically correct the position of the limiting block, ensuring that the rotation process always proceeds along the correct path, improving the reliability of the mechanism.

[0042] Furthermore, the limiting block is provided with a third guide slope 21212, the third guide slope 21212 being inclined in the opposite direction to the first guide slope 21211; the guide block is provided with a fourth guide slope 122, the fourth guide slope 122 being inclined in the opposite direction to the second guide slope 121, and slidingly engaging with the third guide slope 21212 to guide the locking end 212 to rotate.

[0043] Specifically, when the locking end 212 rotates clockwise, the first guide slope 21211 of the limiting block cooperates with the second guide slope 121 of the guide block (in the same direction) and slides along a predetermined trajectory; when the locking end 212 rotates counterclockwise, the third guide slope 21212 of the limiting block (opposite to the first guide slope 21211) cooperates with the fourth guide slope 122 of the guide block (opposite to the second guide slope 121) to achieve reverse guidance, so that the bidirectional rotation of the locking end 212 can be supported by a single structure (the limiting block and the guide block cooperate), without the need for an additional reversing mechanism, thus simplifying the design.

[0044] In addition, the two sets of opposite inclined planes form a symmetrical mechanical structure, which makes the lateral forces generated during rotation cancel each other out, preventing the limit block or guide block from tilting or getting stuck due to unilateral force.

[0045] Furthermore, the locking end 212 is provided with multiple limiting blocks, which are distributed at intervals along the circumference of the locking end 212; multiple guide blocks are provided, which are distributed at intervals along the circumference of the locking groove 11 and are respectively set to correspond to the multiple limiting blocks; multiple first limiting notches 311 are provided, which are distributed at intervals along the circumference of the locking groove 11, so that the multiple limiting blocks can extend into the locking groove 11 through the multiple first limiting notches 311.

[0046] Based on this structure, multiple limit blocks and multiple guide blocks can provide multi-directional alignment. Thus, during assembly, it is not necessary to precisely align a single point. Simply rotate the locking end 212 to the corresponding position of any limit block and guide block to complete the installation, thereby improving assembly efficiency.

[0047] Furthermore, multiple limit blocks and multiple guide blocks form multi-point contact to share the wear during use, reducing the contact frequency between each limit block and each guide block, extending the wear cycle of individual parts, and increasing the service life of the entire structure. At the same time, even if a single limit block or guide block wears out, it can still maintain function through other limit blocks and guide blocks, reducing maintenance frequency.

[0048] Furthermore, the locking mechanism 20 also includes a second elastic member 23, one end of which passes through the force-bearing end 211 and is used to provide an elastic stress to drive the locking end 212 to move closer to the locking groove 11.

[0049] Specifically, when the locking element 21 is connected to the door or other external structure, when the user presses or pulls the force-bearing end 211, the external force overcomes the elastic force of the elastic component, pushing the locking end 212 away from the locking groove 11 (unlocked state). At this time, the elastic component is compressed or stretched, storing elastic potential energy. When the external force is removed, the elastic component releases the stored potential energy, generating a rebound force, driving the locking end 212 to move in the opposite direction, re-inserting into the locking groove 11 and completing the locking. In this way, reset can be achieved without manual operation, improving the ease of use and reliability of the mechanism.

[0050] It should be noted that the second elastic component 23 can also be an existing spring or elastic column structure.

[0051] More specifically, a limiting ring 2111 (such as a protrusion or annular structure on the outer periphery of the force-bearing end 211) is provided at the force-bearing end 211. The limiting ring 2111 extends circumferentially along the force-bearing end 211. When the locking member 21 moves toward the locking groove 11, the limiting ring 2111 can abut against the end wall of the locking groove 11 to restrict the locking end 212 and prevent the locking end 212 from being over-inserted and causing a hard collision with the internal structure of the locking groove 11 (such as a guide block or a limiting notch), thus damaging the mating surface.

[0052] In addition, when the locking member 21 is connected to the door or other external structure, the limiting ring 2111 can also abut against the external structure when the locking end 212 moves close to the locking groove 11, which can also limit the maximum movement distance of the locking end 212 in the direction of the locking groove 11, and prevent the locking end 212 from excessively extending into the locking groove 11, causing jamming or wear.

[0053] Example 2, A refrigerator includes an inner liner 30, a door 40, and the aforementioned locking assembly; a locking seat 10 is detachably connected to the inner liner 30, and a locking mechanism 20 is connected to the door 40.

[0054] Specifically, during assembly, the locking seat 10 can be connected to the inner liner 30, while the locking member 21 is movably inserted into the door 40. When it is necessary to lock the door 40, simply press the force-bearing end 211 of the locking member 21, and the locking end 212 will extend into the locking groove 11. During this process, the second guide portion on the locking end 212 automatically engages and slides with the first guide portion 12 in the locking groove 11, like gears meshing, guiding the locking end 212 to rotate until the first locking part and the second locking part 2121 lock, completing the door locking. To unlock, press the force-bearing end 211 again, and the locking end 212 will rotate, causing the first and second locking parts 2121 to unlock and separate. At this time, the built-in first elastic component 22 releases its elastic force, ejecting the locking end 212 from the locking groove 11, and the door opens accordingly.

[0055] Thus, when closing the door, even if it is not perfectly aligned, as long as the locking part 21 approaches the locking groove 11, the first guide part 12 and the second guide part will automatically slide and engage, guiding the locking end 212 to rotate to lock the second locking part 2121 with the first locking part. Locking or unlocking can be completed without manually calibrating the angle. The entire operation only requires a simple press, making it convenient to operate.

[0056] It should be noted that during installation, a through hole or through groove can be provided on the inner liner 30 to install the locking seat 10, so that the locking end 212 can pass through the inner liner 30 and extend into the locking groove 11.

[0057] Furthermore, the inner liner 30 is provided with a first through-hole 31, which is connected to the locking groove 11; a first locking part is provided on the end wall of the first through-hole 31; the door 40 is provided with a second through-hole 41, which is correspondingly provided to the first through-hole 31 and is connected to each other; the end wall of the second through-hole 41 has a second limiting notch 411, which is correspondingly provided to the second locking part 2121.

[0058] Based on this structure, by providing a first through-hole 31 on the inner liner 30, the first limiting notch 311 in Embodiment 1 can be provided on the end wall of the second through-hole 41, so that after the locking seat 10 is connected to the inner liner 30, the opening of the locking groove 11 forms a first limiting notch 311 (i.e., a first locking part). When there are multiple second locking parts 2121, there can also be multiple first limiting notches 311, and each one is provided in correspondence with the second locking parts 2121, so that multiple second locking parts 2121 can respectively cooperate with multiple first limiting notches 311.

[0059] In addition, a second through-hole 41 is provided on the door 40, through which the locking member 21 is passed, allowing it to move along its own axis under force to extend into or retract from the locking groove 11. A second limiting notch 411 is provided on the first through-hole 31, so that the user can pass the second locking part 2121 through the second limiting notch 411 during installation. Of course, when there are multiple second locking parts 2121, there are also multiple first limiting notches 311, each corresponding to one of them, so that the second locking parts 2121 can be passed through individually later, facilitating user installation.

[0060] The technical means disclosed in this utility model are not limited to those disclosed in the above embodiments, but also include technical solutions composed of any combination of the above technical features. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications are also considered within the scope of protection of this utility model.
