Description
Technical Field
[0001] This utility model relates to the field of door lock technology, specifically to a door lock with a manual unlocking structure. Background Technology
[0002] In a washing machine door lock, when the washing machine suddenly loses power, the door lock remains locked due to the locking mechanism, making it impossible to open the washing machine door.
[0003] Chinese patent document CN115162848A discloses a door lock with a manual unlocking mechanism, comprising: a lock housing, a heart-shaped slider slidably disposed within the lock housing, and a handle disposed outside the lock housing. For manual unlocking, the handle is inserted into the lock housing to actuate the heart-shaped slider.
[0004] However, in the above solution, because the handle protrudes from one side of the lock case, the overall area occupied by the door lock is large, making it unsuitable for use in small spaces. Utility Model Content
[0005] In view of this, the present invention provides a door lock with a manual unlocking structure to solve the problem that existing door locks are inconvenient to use in small spaces.
[0006] This utility model provides a door lock with a manual unlocking mechanism, including:
[0007] The lock housing has a sliding heart-shaped slider inside, which has a locking position for locking the cam and an unlocking position for unlocking the cam.
[0008] The manual unlocking component is a flat plate structure. One side of the manual unlocking component is parallel to the outer wall of the lock housing. The manual unlocking component is movably mounted on the lock housing to drive the heart-shaped slider.
[0009] This utility model provides a door lock with a manual unlocking structure. The heart-shaped slider can be easily unlocked by simply pulling the manual unlocking component. The manual unlocking component is a flat structure that moves parallel to the outer wall of the lock case. This layout effectively utilizes space, making the entire door lock structure more compact and reducing additional space occupation. This facilitates the miniaturization of the door lock design, allowing it to adapt to various door types and installation scenarios.
[0010] Optionally, the manual unlocking component has at least two operating parts extending in opposite directions. This arrangement provides users with diverse operating angles and methods. Different usage scenarios and user habits result in varying requirements for the operating direction. When the door lock is installed on one side of the door and the surrounding space is limited, the user may not be able to operate the manual unlocking component from the conventional direction. In this case, the operating parts extending in opposite directions come in handy, allowing the user to easily apply force from another direction to drive the manual unlocking component and operate the heart-shaped slider, greatly improving the convenience of operation.
[0011] Optionally, the side of the manual unlocking component facing the lock housing has a V-shaped groove, and the axis of symmetry of the V-shaped groove is perpendicular to the direction of movement of the manual unlocking component on the lock housing. With this configuration, when the manual unlocking component is moved, the V-shaped groove drives the heart-shaped slider to move in a direction perpendicular to the direction of movement of the manual unlocking component. In this way, regardless of which of the two operating parts is subjected to pulling force, the heart-shaped slider can be unlocked.
[0012] Optionally, the outer wall of the lock housing has a first limiting structure extending along the moving direction of the manual unlocking member, within which the manual unlocking member slides. This design ensures that the manual unlocking member can only slide within the first limiting structure in a preset direction, effectively preventing deviation or shaking of the manual unlocking member during operation.
[0013] Optionally, the first limiting structure includes: two parallel vertical plates perpendicular to the outer wall of the lock housing and spaced apart, and a horizontal plate connecting the two vertical plates. The manual unlocking component is movably disposed within the space enclosed by the vertical plates and the horizontal plate. The enclosed space formed by the parallel vertical plates and the horizontal plate provides stable support for the manual unlocking component. When the manual unlocking component slides, the vertical plates effectively resist forces from the sides, preventing the manual unlocking component from shaking or shifting laterally; the horizontal plate restricts the vertical movement of the manual unlocking component, further enhancing the stability of the entire structure.
[0014] During installation, the manual unlocking mechanism can be easily inserted into the space enclosed by the vertical and horizontal plates, making operation simple and intuitive. Similarly, it is easy to remove the manual unlocking mechanism from the enclosed space when maintaining or replacing it. This ease of installation and disassembly makes the production, assembly, and subsequent maintenance of the door lock more convenient, reducing labor and time costs.
[0015] Optionally, the lock housing includes an electrical box, and the heart-shaped slider is slidably disposed within the electrical box. The heart-shaped slider has a first protrusion extending out of the electrical box, and the electrical box has a first oblong hole extending along the sliding direction of the heart-shaped slider. The first protrusion of the heart-shaped slider slides within the first oblong hole. In the above solution, the heart-shaped slider and the electrical box are combined to form a modular design. During maintenance, if the electronic components in the heart-shaped slider or the electrical box malfunction, the corresponding module can be easily disassembled and replaced, reducing maintenance costs and difficulty. The first oblong hole extending along the sliding direction of the heart-shaped slider on the electrical box provides precise sliding guidance for the first protrusion of the heart-shaped slider. The sliding of the first protrusion within the first oblong hole restricts the movement trajectory of the heart-shaped slider, ensuring that it can only move in a predetermined direction.
[0016] Optionally, an unlocking lever is movably disposed within the lock housing. The unlocking lever engages with the first protruding portion of the heart-shaped slider to drive the heart-shaped slider towards the unlocked position. In the above solution, by providing an unlocking lever within the lock housing and engaging with the first protruding portion of the heart-shaped slider, a method for indirectly driving the heart-shaped slider is provided to the user. The unlocking lever enriches the manual unlocking operation methods. Compared to directly operating the manual unlocking mechanism, the unlocking lever can be designed with different shapes, sizes, and operating directions to adapt to different users' operating habits and actual usage scenarios.
[0017] The design of the unlocking lever also helps optimize the internal structural layout of the lock case. It can be rationally distributed within the lock case along with other components (such as the electrical box and the heart-shaped slider), making full use of space. The unlocking lever can be arranged along the inner wall of the lock case or on one side of the electrical box, without taking up too much space, while still easily engaging with the first protrusion of the heart-shaped slider. This space optimization makes the internal structure of the lock case more compact, which is beneficial for the miniaturization of door lock designs.
[0018] Optionally, the unlocking lever has a second protrusion extending out of the lock housing, and the lock housing has a second oblong hole extending along the moving direction of the unlocking lever, within which the second protrusion of the unlocking lever slides. In the above solution, the second oblong hole extending along the moving direction of the unlocking lever on the lock housing provides precise guidance for the second protrusion of the unlocking lever. This ensures that the unlocking lever can only slide in a predetermined direction, avoiding deviation or wobbling during operation. The cooperation between the second oblong hole and the second protrusion makes the sliding of the unlocking lever smoother and more stable, providing the user with a better operating feel.
[0019] Optionally, a biasing component is also provided within the lock housing. This biasing component is connected to the unlocking lever and has a biasing force that causes the unlocking lever to move in the direction of releasing the drive of the heart-shaped slider. In the above solution, the biasing component connects to the unlocking lever and provides biasing force, enabling the unlocking lever to automatically move in the direction of releasing the drive of the heart-shaped slider after completing the unlocking action. This configuration ensures that when the door lock is in the locked state, the biasing component prevents the unlocking lever from accidentally unlocking the heart-shaped slider due to slight external vibrations or impacts. The biasing force always acts on the unlocking lever, keeping it in a non-drive position for the heart-shaped slider, thus ensuring the stability of the door lock's locked state.
[0020] Optionally, the inner wall of the lock housing has a second limiting structure extending along the moving direction of the unlocking lever, within which the unlocking lever slides. In the above solution, the second limiting structure extending along the moving direction of the unlocking lever on the inner wall of the lock housing provides precise guidance for the sliding of the unlocking lever. The unlocking lever can only slide along a preset direction within the second limiting structure, effectively preventing the unlocking lever from deviating or wobbling during operation.

[0032] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0033] In the description of this utility model, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0034] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0035] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.
[0036] like Figure 1 As shown, this embodiment provides a specific implementation of a door lock with a manual unlocking structure, including: a lock housing 1 and a manual unlocking component 2. The lock housing 1 has a slidingly disposed heart-shaped slider 8, which has a locking position for locking a cam 15 and an unlocking position for unlocking the cam 15. Specifically, as... Figure 6 As shown, a locking slider 14 is typically installed inside the lock housing 1, which locks the cam 15. When the cam 15 hooks onto the door hook, the locking slider 14 abuts against the flipping path of the cam 15, thus preventing the cam 15 from unlocking. Simultaneously, a locking block 16 protruding from the moving path of the locking slider 14 is provided at its tail. This locking block 16 is driven by the heart-shaped slider 8, and its function is to prevent the locking slider 14 from sliding towards the position where it releases its obstruction of the cam 15. Therefore, the locking and unlocking operation of the cam 15 is achieved entirely through the heart-shaped slider 8.
[0037] like Figure 1 As shown, in this embodiment, the manual unlocking component 2 is a flat plate structure. One side of the manual unlocking component 2 is parallel to the outer wall of the lock housing 1. The manual unlocking component 2 is movably disposed on the lock housing 1 to drive the heart-shaped slider 8.
[0038] The door lock with a manual unlocking mechanism provided in this embodiment can be easily unlocked by simply pulling the manual unlocking component 2, which drives the heart-shaped slider 8. The manual unlocking component 2 is a flat plate structure that moves parallel to the outer wall of the lock housing 1. This layout effectively utilizes space, making the entire door lock structure more compact and reducing additional space occupation. This is beneficial for the miniaturization design of the door lock, allowing it to adapt to various door types and installation scenarios.
[0039] like Figure 2 As shown, in this embodiment, the manual unlocking component 2 has at least two operating parts 3 extending in opposite directions. This arrangement provides users with diverse operating angles and methods. Different usage scenarios and user habits result in varying requirements for the operating direction. When the door lock is installed on one side of the door and the surrounding space is limited, the user may not be able to operate the manual unlocking component 2 from the conventional direction. In this case, the operating parts 3 extending in opposite directions come in handy, allowing the user to easily apply force from another direction to drive the manual unlocking component 2, thereby operating the heart-shaped slider 8, greatly improving the convenience of operation. Of course, the above description is not limiting; in some alternative embodiments, the operating part 3 may also have only one.
[0040] like Figure 3 , Figure 4 As shown, in this embodiment, the side of the manual unlocking member 2 facing the lock housing 1 has a V-shaped groove 4, and the axis of symmetry of the V-shaped groove 4 is perpendicular to the direction of movement of the manual unlocking member 2 on the lock housing 1. With this configuration, when the manual unlocking member 2 is moved, the V-shaped groove drives the heart-shaped slider 8 to move in a direction perpendicular to the direction of movement of the manual unlocking member 2. In this way, regardless of which of the two operating parts 3 is subjected to pulling force, the heart-shaped slider 8 can be unlocked. Of course, the above description is not limiting; in some alternative embodiments, the V-shaped groove can be replaced with grooves of other shapes, such as grooves with a flat bottom and inclined edges on both sides.
[0041] like Figure 5 As shown, in this embodiment, the outer wall surface of the lock case 1 has a first limiting structure extending along the moving direction of the manual unlocking member 2, and the manual unlocking member 2 slides within the first limiting structure. Through this design, the manual unlocking member 2 can only slide within the first limiting structure in a preset direction, effectively preventing the manual unlocking member 2 from shifting or shaking during operation.
[0042] like Figure 5 As shown, the first limiting structure includes two parallel vertical plates 5 perpendicular to the outer wall of the lock housing 1 and a horizontal plate 6 connecting the two vertical plates 5. The manual unlocking component 2 is movably disposed within the space enclosed by the vertical plates 5 and the horizontal plate 6. The enclosed space formed by the parallel vertical plates 5 and the horizontal plate 6 provides stable support for the manual unlocking component 2. When the manual unlocking component 2 slides, the vertical plates 5 effectively resist forces from the sides, preventing the manual unlocking component 2 from shaking or shifting laterally; the horizontal plate 6 restricts the vertical movement of the manual unlocking component 2, further enhancing the stability of the entire structure.
[0043] During installation, the manual unlocking component 2 can be easily inserted into the space enclosed by the vertical plate 5 and the horizontal plate 6, making the operation simple and intuitive. Similarly, when maintaining or replacing the manual unlocking component 2, it is also easy to remove it from the enclosed space. This ease of installation and disassembly makes the production, assembly, and subsequent maintenance of the door lock more convenient, reducing labor and time costs.
[0044] like Figure 6As shown, in this embodiment, the lock housing 1 contains an electrical box 7, and the heart-shaped slider 8 is slidably disposed within the electrical box 7. The heart-shaped slider 8 has a first protruding portion 9 extending out of the electrical box 7. The electrical box 7 has a first oblong hole 10 extending along the sliding direction of the heart-shaped slider 8, and the first protruding portion 9 of the heart-shaped slider 8 slides within the first oblong hole 10. In the above solution, the heart-shaped slider 8 and the electrical box 7 are combined to form a modular design. During maintenance, if the electronic components inside the heart-shaped slider 8 or the electrical box 7 malfunction, the corresponding module can be easily disassembled and replaced, reducing maintenance costs and difficulty. The first oblong hole 10 extending along the sliding direction of the heart-shaped slider 8 on the electrical box 7 provides precise sliding guidance for the first protruding portion 9 of the heart-shaped slider 8. The sliding of the first protruding portion 9 within the first oblong hole 10 restricts the movement trajectory of the heart-shaped slider 8, ensuring that it can only move in a predetermined direction.
[0045] like Figure 6 As shown, in this embodiment, an unlocking lever 11 is movably disposed within the lock housing 1. The unlocking lever 11 cooperates with the first protruding portion 9 of the heart-shaped slider 8 to drive the heart-shaped slider 8 towards the unlocked position. In the above solution, by providing an unlocking lever 11 within the lock housing 1 and cooperating with the first protruding portion 9 of the heart-shaped slider 8, an indirect method of driving the heart-shaped slider 8 is provided to the user. The unlocking lever 11 enriches the manual unlocking operation methods. Compared with directly operating the manual unlocking component 2, the unlocking lever 11 can be designed with different shapes, sizes, and operating directions to adapt to different users' operating habits and actual usage scenarios.
[0046] The design of the unlocking lever 11 also helps optimize the internal structural layout of the lock housing 1. It can be rationally distributed within the lock housing 1 along with other components (such as the electrical box 7, the heart-shaped slider 8, etc.), making full use of space. The unlocking lever 11 can be arranged along the inner wall of the lock housing 1 or on one side of the electrical box 7, without occupying excessive space, while easily engaging with the first protruding part 9 of the heart-shaped slider 8. This space optimization makes the internal structure of the lock housing 1 more compact, which is beneficial for the miniaturization design of the door lock.
[0047] like Figure 6As shown, in this embodiment, the unlocking lever 11 has a second protrusion 12 extending out of the lock housing 1. The lock housing 1 has a second oblong hole 13 extending along the moving direction of the unlocking lever 11. The second protrusion 12 of the unlocking lever 11 slides within the second oblong hole 13. In the above solution, the second oblong hole 13 extending along the moving direction of the unlocking lever 11 on the lock housing 1 provides precise guidance for the second protrusion 12 of the unlocking lever 11. This ensures that the unlocking lever 11 can only slide along a predetermined direction, avoiding deviation or shaking during operation. The cooperation between the second oblong hole 13 and the second protrusion 12 makes the sliding of the unlocking lever 11 smoother and more stable, providing the user with a better operating feel. Of course, the above description is not limiting. In some alternative embodiments, the unlocking lever 11 can be omitted, and the manual unlocking component 2 can directly drive the heart-shaped slider 8.
[0048] like Figure 7 As shown, in this embodiment, the heart-shaped slider 8 inside the electrical box 7 is connected to the electromagnetic drive mechanism 17. During normal operation, the electromagnetic drive mechanism 17 drives the heart-shaped slider 8 to move within the electrical box 7. The heart-shaped slider 8 is linked to the locking block 16 inside the electrical box. When the heart-shaped slider 8 moves to the unlocked position, the locking block 16 retracts into the electrical box 7 under the action of the heart-shaped slider 8. When the heart-shaped slider 8 moves to the locked position, the locking block 16 extends out of the electrical box 7 under the action of the heart-shaped slider 8, thereby blocking the movement path of the tail of the locking slider 14 outside the electrical box, preventing the locking slider 14 from moving backward to unlock, thus maintaining the lock on the cam 15.
[0049] like Figure 8 As shown, in this embodiment, a biasing component is also provided inside the lock housing 1. The biasing component is connected to the unlocking lever 11, and the biasing component has a biasing force that causes the unlocking lever 11 to move in the direction of releasing the drive of the heart-shaped slider 8. Specifically, the biasing component can be a spring, torsion spring, etc. In the above scheme, the biasing component is connected to the unlocking lever 11 and provides a biasing force, so that after the unlocking lever 11 completes the unlocking action of driving the heart-shaped slider 8, it can automatically move in the direction of releasing the drive of the heart-shaped slider 8. With this setting, when the door lock is in the locked state, the biasing component ensures that the unlocking lever 11 will not accidentally drive the heart-shaped slider 8 to unlock due to slight external vibrations or collisions. The biasing force always acts on the unlocking lever 11, keeping it in a position where it does not drive the heart-shaped slider 8, thus ensuring the stability of the door lock's locked state.
[0050] like Figure 8As shown, in this embodiment, the inner wall of the lock housing 1 has a second limiting structure extending along the moving direction of the unlocking lever 11, and the unlocking lever 11 slides within the second limiting structure. In the above solution, the second limiting structure extending along the moving direction of the unlocking lever 11 on the inner wall of the lock housing 1 provides precise guidance for the sliding of the unlocking lever 11. The unlocking lever 11 slides within the second limiting structure and can only be displaced along a preset direction, effectively preventing the unlocking lever 11 from deviating or shaking during operation. Specifically, the second limiting structure includes: limiting ribs 18, which have two parallel and spaced ribs arranged inside the lock housing 1 and on both sides of the second oblong hole 13, and a portion of the unlocking lever 11 slides between the two limiting ribs 18.
[0051] Manual unlocking principle: The manual unlocking component 2 is a flat plate structure and is movably arranged parallel to the outer wall of the lock housing 1. By pulling the manual unlocking component 2, its V-shaped groove 4 drives the unlocking lever 11 to move in a direction perpendicular to the moving direction of the manual unlocking component 2. The unlocking lever 11 drives the heart-shaped slider 8 to move. When the heart-shaped slider 8 moves, it drives the locking block 16 to move. When the heart-shaped slider 8 is in the unlocked position, the locking block 16 retracts into the electrical box 7, releasing the obstruction to the locking slider 14, thereby unlocking the cam 15.
[0052] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the scope defined by the present invention.
