[0052] The embodiments of the present invention will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below by referring to the drawings are exemplary and are only used to explain the present invention and should not be construed as a limitation of the present invention.

[0053] The following refers to Figure 1-Figure 16 Describe the door lock structure 100 according to an embodiment of the present invention.

[0054] The door lock structure 100 according to an embodiment of the present invention is applicable to a functional device, and the functional device includes a door body and a box body that are openably and closably connected.

[0055] For example, the functional device is a household appliance, such as a cooking appliance like a microwave oven. In the following embodiments, the microwave oven is used as an example for illustration. The oven body of the microwave oven is the box body, and the oven door of the microwave oven is the door body. Among them, a heating space is formed in the box body, and the heating space has an open mouth. Food is suitable to be put into the heating space or taken out from the open mouth. The door body is arranged at the open mouth, and the door body is openably and closably connected to the box body so that the door body can move relative to the box body to realize the opening and closing actions of the door body.

[0056] As Figure 1 shown, the door lock structure 100 includes: a snap-on handle 10, a locking bracket 20, and a drive assembly 30.

[0057] Specifically, the snap-on handle 10 is installed on the door body and includes a snap-in portion 11. The locking bracket 20 is installed on the box body and includes a limiting portion 21 that is in limit fit with the snap-in portion 11. The driving assembly 30 includes a driving member 31, a reset member 32, and a sliding stopper 33. The sliding stopper 33 is slidably installed on the locking bracket 20. The driving member 31 is used to drive the sliding stopper 33 to slide from the locked position to the unlocked position, and the reset member 32 is used to drive the sliding stopper 33 to slide from the unlocked position to the locked position. Among them, when in the locked position, the sliding stopper 33 presses against the snap-in portion 11 and is used to limit the relative separation of the snap-in portion 11 and the limiting portion 21. When in the unlocked position, the sliding stopper 33 is spaced apart from the snap-in portion 11 and the snap-in portion 11 and the limiting portion 21 can be relatively separated.

[0058] It can be understood that the snap-on handle 10 is installed on the door body, the driving assembly 30 is installed on the locking bracket 20, and the locking bracket 20 is installed on the box body. As Figure 6 shown, the snap-on handle 10 includes a handle 12 and a snap-in portion 11. There are two snap-in portions 11, and the two snap-in portions 11 are arranged at intervals. And as Figure 7 shown, the locking bracket 20 is provided with two limiting portions 21, and the two snap-in portions 11 correspond to the two limiting portions 21 one by one.

[0059] Specifically, the handle 12 is located on the side of the door body facing away from the box body. The snap-in portion 11 is adapted to pass through the locking bracket 20 in the second direction to be in snap fit with the limiting portion 21, and the limiting portion 21 limits the snap-in portion 11 in the second direction, facilitating the user to push the handle 12 to make the snap-in portion 11 and the limiting portion 21 snap together to realize the closing action of the door body, and then close the box body. At this time, the door body is in the closed state, or the user can pull the handle 12 to separate the snap-in portion 11 from the limiting portion 21 to realize the opening action of the door body, and then open the box body. At this time, the door body is in the open state.

[0060] For example, in the actual opening action: The user can first control the snap-on handle 10 to move relative to the locking bracket 20 in the first direction (such as Figure 2 the vertical direction in Figure 2 ) towards the direction away from the limiting portion 21 to separate the snap-in portion 11 from the limiting portion 21. Then the user pulls the door body in the second direction (such as

[0061] the horizontal direction in Figure 2 ) towards the direction away from the box body to open the door body. Figure 2Control the clamping part 11 to move in the direction towards the limiting part 21 in the vertical direction, so that the clamping part 11 and the limiting part 21 are in limiting cooperation to close the door body.

[0062] Further, as Figure 1 shown, the driving assembly 30 includes a driving member 31, a reset member 32 and a sliding stopper 33.

[0063] Preferably, the driving assembly 30 is arranged above one of the two limiting parts 21. Specifically, the sliding stopper 33 is slidably engaged with the locking bracket 20 in the second direction, that is, the sliding stopper 33 can move relative to the locking bracket 20 in the second direction, and the sliding stopper 33 is adapted to abut against or separate from the clamping part 11.

[0064] Wherein, the sliding stopper 33 has an unlocking position and a locking position, and the sliding stopper 33 is adapted to slide between the unlocking position and the locking position. When the sliding stopper 33 is located at the unlocking position, the sliding stopper 33 is separated from the clamping part 11 to unlock the clamping part 11. At this time, the clamping part 11 can be separated from the limiting part 21 to facilitate opening the door body. When the sliding stopper 33 is located at the locking position, the sliding stopper 33 abuts against the clamping part 11 to lock the clamping part 11. At this time, the sliding stopper 33 limits the clamping part 11 to prevent the clamping part 11 from separating from the limiting part 21.

[0065] Thus, by changing the position of the sliding stopper 33, the unlocking or locking of the clamping part 11 can be realized, so as to control whether the clamping part 11 can be separated from the limiting part 21, and further control whether the door body can be opened.

[0066] Wherein, the driving member 31 is used to drive the sliding stopper 33 to slide from the locking position to the unlocking position, that is, to separate the sliding stopper 33 from the clamping part 11. That is, the driving member 31 is used to unlock the clamping part 11 so that the clamping part 11 and the limiting part 21 can be relatively separated, facilitating the user to open the door body. Then the user can place food in the box or take it out of the box.

[0067] Thus, the user needs to unlock the clamping part 11 first, and after the clamping handle 10 and the locking bracket 20 are unlocked, the user can open or close the door body, thereby solving the problem that the door lock structure 100 is too simple, that is, the door lock structure 100 has a child lock function to prevent children from accidentally opening the door body and being scalded by high-temperature items in the box, which is beneficial to enhancing the use safety of the functional equipment.

[0068] Further, when the door body is in the closed state, the reset member 32 is used to drive the sliding block 33 to slide from the unlocking position to the locking position, so that the sliding block 33 can automatically reset, and the sliding block 33 presses against the clamping portion 11 and is used to restrict the relative separation of the clamping portion 11 and the limiting portion 21, which is beneficial to enhancing the clamping stability between the clamping portion 11 and the limiting portion 21 to achieve the locking of the door body.

[0069] It should be noted that when the door body is in the open state, the reset member 32 can also drive the sliding block 33 to slide from the unlocking position to the locking position, so that the sliding block 33 can automatically reset. At this time, the sliding block 33 directly abuts against the limiting portion 21.

[0070] Thus, whether the door body is in the open state or the closed state, the reset member 32 can drive the sliding block 33 to slide from the unlocking position to the locking position, so that the sliding block 33 can automatically reset, and thus there is no need for manual control of the reset of the sliding block 33, which is convenient for reducing the use difficulty of the door lock structure 100.

[0071] According to the door lock structure 100 of the embodiment of the present invention, the driving member 31 can drive the sliding block 33 to slide from the locking position to the unlocking position, so that the clamping portion 11 and the limiting portion 21 can be relatively separated, and then the clamping handle 10 can drive the door body to perform an opening action, and the reset member 32 can drive the sliding block 33 to slide from the unlocking position to the locking position, which is convenient for the sliding block 33 to slide relative to the locking bracket 20 to automatically reset. Such a setting enables the door lock structure 100 to have a child lock function to prevent children from accidentally opening the door body and being scalded by high-temperature items in the box, which is beneficial to enhancing the use safety of the functional device.

[0072] In some embodiments, as Figure 2-Figure 5 shown, the sliding block 33 is provided with a first inclined surface 3311, and the driving member 31 is provided with an output rod 311. The output rod 311 is adapted to press against the first inclined surface 3311 along a first direction and cause the sliding block 33 to slide along a second direction to the unlocking position.

[0073] It can be understood that the first inclined surface 3311 is inclined in the first direction, that is, the extending direction of the first inclined surface 3311 intersects with the first direction. Thus, when the driving member 31 drives the sliding block 33 to slide from the locking position to the unlocking position, the end of the output rod 311 presses against the first inclined surface 3311 and applies a driving force to the sliding block 33 along the first direction. At this time, the component force of the driving force in the second direction pushes the sliding block 33 to slide along the second direction away from the clamping portion 11. When the sliding block 33 slides to the unlocking position, the sliding block 33 is separated from the clamping portion 11 to achieve the unlocking of the clamping portion 11, so that the clamping portion 11 can be separated relative to the limiting portion 21, and then it is convenient for the user to open the door body.

[0074] Furthermore, if Figure 3 , Figure 5 , Figure 8 and Fig. 9 As shown, a driving inclined surface 3111 is provided at the end of the output rod 311 . Optionally, the driving inclined surface 3111 is arranged parallel to the first inclined surface 3311 , and the driving inclined surface 3111 is slidably fitted with the first inclined surface 3311 .

[0075] Specifically, a driving bevel 3111 is provided at the end of the output rod 311 facing the sliding block 33, and the extension direction of the driving bevel 3111 intersects with the first direction and is parallel to the extension direction of the first bevel 3311, so that the driving bevel 3111 is suitable for sliding cooperation with the first bevel 3311.

[0076] When the active member 31 drives the sliding block 33 to slide from the locked position to the unlocked position, the end of the output rod 311 presses against the first inclined surface 3311 and applies a driving force to the sliding block 33 along the first direction. At this time, the driving inclined surface 3111 and the first inclined surface 3311 are slidably matched, so that the sliding block 33 can be driven to slide by a smaller driving force.

[0077] Therefore, by setting the driving inclined surface 3111 and the first inclined surface 3311, the driving direction of the driving force of the active component 31 acting on the sliding block 33 can be changed, so that the driving force output by the active component 31 along the first direction can drive the sliding block 33 to move along the second direction, so as to reduce the structural dimensions of the door lock structure 100 in the first direction, which is conducive to the miniaturization design of the door lock structure 100.

[0078] Preferably, the first direction is perpendicular to the second direction.

[0079] It should be noted that the first direction is the downward direction perpendicular to the ground when the functional device is placed on a horizontal plane, and the second direction is the direction parallel to the ground. Therefore, when the output rod 311 applies a driving force to the sliding block 33 along the first direction, the component of the driving force in the second direction can push the sliding block 33 to slide along the second direction toward the direction away from the clamping portion 11, so as to unlock the clamping portion 11.

[0080] In some embodiments, the return member 32 is configured as a spring and is used to provide an elastic force toward the sliding stopper 33 .

[0081] For example, the reset member 32 is located on the side of the sliding block 33 facing the locking bracket 20, or the reset member 32 is located on the side of the sliding block 33 away from the locking bracket 20, so that the reset member 32 can use elasticity to provide elastic force to the sliding block 33. In other words, the reset member 32 can use the elastic force to drive the sliding block 33 to slide from the unlocked position to the locked position.

[0082] Among them, Fig.14 and Fig.15 As shown, the sliding block 33 is further provided with a second inclined surface 3321, and as Figure 3 shown, the clamping portion 11 abuts against the second inclined surface 3321. When the clamping handle 10 is driven to move away from the box body to overcome the elastic force of the reset member 32, the clamping portion 11 slides along the second inclined surface 3321 and is relatively separated from the limiting portion 21, and at the same time, the sliding block 33 moves towards the unlocking position.

[0083] It can be understood that the second inclined surface 3321 is provided on one side of the sliding block 33 facing the clamping portion 11, and the second inclined surface 3321 is adapted to abut against the clamping portion 11. Wherein, when the sliding block 33 is in the locked position, as Figure 3 shown, the clamping portion 11 abuts against the second inclined surface 3321, so as to limit the clamping portion 11 through the sliding block 33, prevent the clamping portion 11 from separating from the limiting portion 21, and enhance the clamping stability between the clamping portion 11 and the limiting portion 21.

[0084] Further, when the clamping handle 10 is driven to move away from the box body to overcome the elastic force of the reset member 32, the clamping portion 11 slides along the second inclined surface 3321 and is relatively separated from the limiting portion 21, and at the same time, the sliding block 33 moves towards the unlocking position to unlock the clamping portion 11.

[0085] Thus, by providing the second inclined surface 3321, it is convenient for the clamping portion 11 to slide along the second inclined surface 3321 to overcome the elastic force of the reset member 32, and further facilitate reducing the unlocking difficulty of the clamping portion 11.

[0086] Preferably, as Figure 3 、 Figure 5 and Figure 6 shown, the clamping portion 11 is provided with a pressing inclined surface 111, and the pressing inclined surface 111 abuts against the second inclined surface 3321 and slides relative to the second inclined surface 3321.

[0087] It can be understood that, as Figure 3 shown, when the sliding block 33 is in the locked position, the pressing inclined surface 111 abuts against the second inclined surface 3321 to limit the clamping portion 11 and prevent the clamping portion 11 from separating from the limiting portion 21. And when the sliding block 33 moves from the locked position to the unlocking position, the pressing inclined surface 111 slides in cooperation with the second inclined surface 3321, that is, the sliding block 33 and the clamping portion 11 slide in cooperation along the inclined surface, thereby reducing the movement difficulty of the sliding block 33.

[0088] For example, the second inclined surface 3321 is provided on the side of the sliding block 33 facing the clamping portion 11, and the second inclined surface 3321 is inclined in the second direction, that is, the extending direction of the second inclined surface 3321 intersects with the second direction. The pressing inclined surface 111 is provided on the side of the clamping portion 11 facing the sliding block 33, and the pressing inclined surface 111 is inclined in the second direction, that is, the extending direction of the second inclined surface 3321 intersects with the second direction. Thus, when the user opens the door body, first, the driving member 31 drives the sliding block 33 to move in the second direction away from the clamping portion 11. At this time, the sliding block 33 and the clamping portion 11 are in sliding cooperation along the inclined surface, so as to reduce the unlocking difficulty of the clamping portion 11.

[0089] Optionally, the included angle between the plane where the pressing inclined surface 111 is located and the plane where the second inclined surface 3321 is located is less than 45°.

[0090] For example, the included angle between the plane where the pressing inclined surface 111 is located and the plane where the second inclined surface 3321 is located can be 10°, or the included angle between the plane where the pressing inclined surface 111 is located and the plane where the second inclined surface 3321 is located can be 20°. Or the plane where the pressing inclined surface 111 is located is parallel to the plane where the second inclined surface 3321 is located. That is, when the included angle between the plane where the pressing inclined surface 111 is located and the plane where the second inclined surface 3321 is located satisfies the above value range, when the user drives the clamping handle 10 to move away from the box body against the elastic force of the reset member 32, the clamping portion 11 moves in the first direction, and the clamping portion 11 generates a thrust on the sliding block 33 in the first direction. At this time, the separation of the thrust in the second direction can drive the sliding block 33 to slide in the second direction to overcome the elastic force of the reset member 32, so as to realize the unlocking of the sliding block 33 to the clamping portion 11, and then it is convenient for the user to forcibly open or close the door body.

[0091] For example, when the sliding block 33 is in the locked position and the driving member 31 does not work, that is, when the driving member 31 cannot drive the sliding block 33 to move from the locked position to the unlocked position, when the user wants to open the door body, the user can first drive the clamping handle 10 to move relative to the locking bracket 20 in the first direction, that is, the clamping portion 11 moves in the first direction away from the limiting portion 21. At this time, the clamping portion 11 generates a thrust on the sliding block 33 in the first direction, that is, the thrust acts on the second inclined surface 3321. When the component force of the thrust in the second direction is sufficient to overcome the elastic force of the reset member 32, the pressing inclined surface 111 and the sliding inclined surface are in sliding cooperation, so that the sliding block 33 moves in the second direction away from the clamping portion 11 to realize the unlocking of the clamping portion 11, and then the forced opening of the door can be completed.

[0092] Alternatively, after the door body is opened, when the sliding block 33 is in the locked position and the driving member 31 is not working, that is, when the driving member 31 cannot drive the sliding block 33 to move from the locked position to the unlocked position, when the user wants to close the door body, the user can first drive the clamping handle 10 to move relative to the locking bracket 20 in the second direction, that is, the clamping portion 11 extends into the locking bracket 20 in the second direction and abuts against the second inclined surface 3321 in the second direction. At this time, the clamping portion 11 generates a thrust on the sliding block 33 in the second direction, that is, the thrust acts on the second inclined surface 3321. When the thrust is sufficient to overcome the elastic force of the reset member 32, the pressing inclined surface 111 and the sliding inclined surface are in sliding fit, so that the sliding block 33 moves in the second direction away from the clamping portion 11. Then, the clamping portion 11 moves toward the limiting portion 21 in the first direction to achieve the clamping fit between the clamping portion 11 and the limiting portion 21. Then, the sliding block 33 will automatically reset under the action of the reset member 32 to press against the clamping portion 11 to prevent the clamping portion 11 from separating from the limiting portion 21, and the forced closing of the door can be completed.

[0093] It should be noted that in the prior art, when the electromagnetic lock (driving member 31) cannot work, the user cannot achieve forced opening or closing of the door. In the present invention, by providing the first inclined surface 3311 and the second inclined surface 3321 on the sliding block 33, and providing the driving inclined surface 3111 and the pressing inclined surface 111 on the output rod 311 and the clamping portion 11 respectively, the sliding block 33 and the driving member 31 and the clamping portion 11 are all in sliding fit along the inclined surface, so that the forced opening or closing of the door body can be realized.

[0094] In some embodiments, such as Figure 4 and Figure 5 shown, the reset member 32 is configured as a spring and is used to provide an elastic force toward the sliding block 33. The reset member 32 is connected between one side of the sliding block 33 facing the clamping portion 11 and the locking bracket 20.

[0095] It can be understood that the reset member 32 is elastically connected between the locking bracket 20 and the sliding block 33 in the second direction, that is, one end of the reset member 32 is connected to the locking bracket 20, and the other end of the reset member 32 is connected to the sliding block 33, and the reset member 32 is used to provide an elastic force for the sliding block 33 to approach the locking bracket 20.

[0096] Thus, by providing the reset member 32, when the sliding block 33 is not stressed, it can automatically reset through the elastic force of the reset member 32.

[0097] Furthermore, as Fig.12 and Fig.13As shown, the sliding block 33 is provided with an escape space 334, a fixing rod 335 is provided in the escape space 334, and one end of the reset member 32 extends into the escape space 334 and is connected to the fixing rod 335. In other words, the escape space 334 extends along the second direction, and the escape space 334 has an open opening at one end facing the clamping portion 11, and the fixing rod 335 is provided on the inner wall of the escape space 334 at one end away from the clamping portion 11, so that the reset member 32 can extend into the escape space 334 along the second direction, and the reset member 32 can be fixed by the fixing rod 335, so as to enhance the structural stability of the reset member 32, and further facilitate the escape space 334 to guide the expansion and contraction of the reset member 32.

[0098] For example, Figure 2 As shown, when the sliding block 33 is in the locked position, most of the reset member 32 extends into the avoidance space 334 to reduce the installation space occupied by the reset member 32 and make the reset member 32 not directly visible from the outside, which is conducive to the miniaturization design of the door lock structure 100.

[0099] like Figure 3 As shown, when the sliding block 33 is in the unlocked position, the active member 31 drives the sliding block 33 to move along the second direction toward the direction away from the clamping portion 11. At this time, the reset member 32 is stretched to utilize the elastic force of the reset member 32 to restore the initial length to generate a pulling force on the reset member 32, and then when the active member 31 is retracted, the sliding block 33 can be reset by the elastic force of the reset member 32, that is, the sliding block 33 is pulled from the unlocked position to the locked position by the elastic force of the reset member 32.

[0100] Preferably, one of the locking bracket 20 and the sliding block 33 is provided with a sliding rail 22 , and the other is provided with a sliding groove 3333 , and the sliding rail 22 and the sliding groove 3333 are slidably matched.

[0101] For example, the locking bracket 20 is provided with a sliding guide rail 22, and the sliding block 33 is provided with a sliding groove 3333, or the locking bracket 20 is provided with a sliding groove 3333, and the sliding block 33 is provided with a sliding guide rail 22, and the sliding guide rail 22 and the sliding groove 3333 are slidably matched. In other words, the locking bracket 20 and the sliding block 33 are slidably matched to reduce the difficulty of movement of the sliding block 33, and at the same time, can guide the movement of the sliding block 33, thereby ensuring that the sliding block 33 can slide along the second direction.

[0102] Of course, the locking bracket 20 and the sliding block 33 may also be in other sliding matching forms. For example, the locking bracket 20 and the sliding block 33 may both be provided with sliding surfaces, which is not limited here.

[0103] In some embodiments, Figure 12-Figure 15As shown, the sliding block 33 includes a first mating portion 331, a second mating portion 332, and a main body portion 333. Preferably, the first mating portion 331, the second mating portion 332, and the main body portion 333 can be integrally formed parts.

[0104] Specifically, the first mating portion 331 is connected to one side of the main body portion 333 and is used for pressing and mating with the driving member 31, and the second mating portion 332 is connected to the other side of the main body portion 333 and is used for pressing and mating with the clamping portion 11.

[0105] It can be understood that the first mating portion 331 and the second mating portion 332 are respectively located on both sides of the main body portion 333, and the first mating portion 331 extends in the direction of the driving member 31, and the second mating portion 332 extends in the direction of the clamping portion 11. Among them, a first inclined surface 3311 is provided on the first mating portion 331 and is used for abutting against the driving inclined surface 3111 of the output rod 311, and a second inclined surface 3321 is provided on the second mating portion 332 and is used for abutting against the pressing inclined surface 111 of the clamping portion 11.

[0106] Furthermore, the main body portion 333 is slidably mated with the locking bracket 20, and / or the main body portion 333 is connected to the reset member 32.

[0107] For example, as Figure 7 shown, the locking bracket 20 is provided with a sliding guide rail 22, and as Fig.12 and Fig.13 shown, the main body portion 333 is provided with a chute. Preferably, there are two sliding guide rails 22, and the two sliding guide rails 22 extend in the second direction. There are also two chutes, and the two chutes correspond to the two sliding guide rails 22 one by one, so as to facilitate the main body portion 333 to slide along the sliding guide rail 22.

[0108] Thereby, it is convenient to reduce the sliding difficulty of the main body portion 333. At the same time, it can play a guiding role in the movement of the main body portion 333, and further ensure that the main body portion 333 can slide along the second direction.

[0109] In some embodiments, as Figure 8-Figure 11 shown, the driving member 31 includes: a mounting frame 312, a power source 313, and an output rod 311.

[0110] Specifically, the mounting frame 312 is connected to the locking bracket 20, the power source 313 is mounted on the mounting frame 312, the output rod 311 is mounted on the power source 313, and the power source 313 is used to drive the output rod 311 to push the sliding block 33 to slide.

[0111] For example, the locking bracket 20 is provided with a connecting portion 23, and the mounting bracket 312 is detachably connected to the connecting portion 23, so as to detachably mount the driving member 31 on the locking bracket 20, thereby enhancing the structural stability of the driving member 31. Moreover, the output rod 311 is power-connected to the power source 313, so that the power source 313 can drive the output rod 311 to move. Furthermore, the output rod 311 can press against the sliding block 33, so that the sliding block 33 slides in the second direction away from the clamping portion 11, thereby realizing the unlocking of the clamping portion 11.

[0112] Furthermore, as Figure 8-Figure 11 shown, the output rod 311 passes through the power source 313. The power source 313 is configured to drive the output rod 311 to move towards the sliding block 33 after being powered on, and drive the output rod 311 to move away from the sliding block 33 after a set power-on time.

[0113] It can be understood that the power source 313 is configured as a solenoid valve, and the output end of the solenoid valve is connected with the output rod 311. After the solenoid valve is powered on, it drives the output rod 311 to move towards the sliding block 33, and enables the output rod 311 to press against the sliding block 33, so that the sliding block 33 slides in the second direction away from the clamping portion 11, thereby realizing the unlocking of the clamping portion 11.

[0114] Then, the solenoid valve drives the output rod 311 to move away from the sliding block 33 after the set power-on time. In other words, the output rod 311 no longer presses against the sliding block 33. That is, after the set time, regardless of whether the door body is closed or not, the output rod 311 is separated from the sliding block 33. Then, under the elastic force of the reset member 32, the sliding block 33 resets, that is, the sliding block 33 slides from the unlocking position to the locking position.

[0115] It should be noted that the set time can be freely set by the user. For example, the set time can be 10s, or the set time can be 15s. Of course, the set time can also be other values, which are not limited herein.

[0116] Thus, through such a setting, after the door body is closed, without manual control, the sliding block 33 can automatically reset after the set time to realize the locking of the clamping portion 11. Or, after the door body is opened but not closed, the sliding block 33 can still automatically reset after the set time. At this time, the user does not need to re-control the driving member 31 to unlock the clamping portion 11, and the closing of the door body can still be realized through the sliding cooperation between the clamping portion 11 and the sliding block 33 along the inclined plane.

[0117] The present invention also proposes a functional device.

[0118] The functional device according to an embodiment of the present invention includes a door body, a box body, and the door lock structure 100 in any one of the above embodiments.

[0119] In the functional device according to an embodiment of the present invention, the driving member 31 of the door lock structure 100 can drive the sliding block 33 to slide from the locked position to the unlocked position, so that the clamping portion 11 and the limiting portion 21 can be relatively separated, and then the clamping handle 10 can drive the door body to perform an opening action. Moreover, the reset member 32 can drive the sliding block 33 to slide from the unlocked position to the locked position, facilitating the sliding block 33 to slide relative to the locking bracket 20 to automatically reset. With such a setting, the door lock structure 100 has a child lock function to prevent children from accidentally opening the door body and being scalded by high-temperature items in the box body, which is beneficial to enhancing the use safety of the functional device.

[0120] Furthermore, the functional device further includes: an operation button and / or a driving structure.

[0121] Specifically, the operation button is installed on the door body or the box body and is electrically connected to the driving member 31. The operation button is used to control the power on and off of the driving member 31, and / or the driving structure. The driving structure is movably installed on the door body or the box body, and the driving structure is used to drive the clamping portion 11 and the limiting portion 21 to be relatively separated.

[0122] It can be understood that in some examples, if the hook type of the clamping portion 11 is a straight hook, an inverted hook, etc., the clamping portion 11 has a self-locking function, and an additional driving structure is required after the child lock is released. Then the functional device includes: an operation button and a driving structure, wherein the driving structure is used to drive the clamping portion 11 and the limiting portion 21 to be relatively separated to open the door body.

[0123] In other examples, if the hook type of the clamping portion 11 is an arc hook, that is, the clamping portion 11 has no self-locking function, then no additional driving structure is required after the child lock is released, and the driving structure may not be provided. That is, the functional device includes: an operation button. At this time, the user can directly pull open the door body.

[0124] Furthermore, the control button is electrically connected to the driving member 31. That is, after the control button is pressed, the driving member 31 is powered on to drive the sliding block 33 to move from the locked position to the unlocked position, and after the set power-on time, the driving member 31 is automatically powered off. The driving structure is used to drive the clamping portion 11 and the limiting portion 21 to be clamped or relatively separated, wherein the driving structure can be an electric drive or a mechanical drive.

[0125] Preferably, in the present invention, the driving structure and the clamping portion 11 are mechanically driven.

[0126] For example, the driving structure includes a mechanical button and a transmission structure. The mechanical button is provided on the door body or the box body, and the transmission structure is connected to the clamping portion 11.

[0127] For example, in an actual door opening operation: The user first presses the operation button to energize the driving member 31 to drive the sliding block 33 to move from the locked position to the unlocked position. Then the user presses the mechanical button, so that the transmission structure drives the clamping handle 10 to move relative to the locking bracket 20 in the first direction (such as Figure 2 the vertical direction in) away from the limiting portion 21, so that the clamping portion 11 is separated from the limiting portion 21. Then the user pulls the clamping handle 10 in the second direction (such as Figure 2 the horizontal direction in) away from the box body to open the door body.

[0128] It should be noted that, in the case of power failure, or when the control button or the driving member 31 fails, since the driving member 31 cannot drive the sliding block 33 to move from the locked position to the unlocked position, at this time, the user can first apply a large driving force to the clamping handle 10 in the first direction. This driving force acts on the second inclined surface 3321 and extends upward in the first direction, that is, the user can pull the clamping handle 10 upward. When the component force of this driving force in the second direction is greater than the elastic force of the reset member 32, the clamping portion 11 can move in the first direction to push the sliding block 33 to slide from the locked position to the unlocked position. At this time, the sliding block 33 and the driving member 31 slide relative to each other along the inclined surface, thereby realizing the forced opening of the door body.

[0129] In an actual door closing operation: The user first pushes the clamping handle 10 along the upper side of the limiting portion 21 into the locking bracket 20 in the second direction (such as Figure 2 the horizontal direction in), and makes the clamping portion 11 push the sliding block 33 to slide from the locked position to the unlocked position. Then drive the clamping handle 10 to move in the first direction (such as Figure 2 the vertical direction in) towards the limiting portion 21, so that the clamping portion 11 is in limit cooperation with the limiting portion 21 to close the door body.

[0130] Therefore, in the case of power failure, or when the control button or the driving member 31 fails, the driving structure can still work normally, so that the user can still forcibly open or close the door body, thereby facilitating the reduction of the difficulty of opening and closing the door body.

[0131] The present invention also proposes a control method for a door lock structure.

[0132] The control method for the door lock structure according to the embodiment of the present invention is applicable to the door lock structure 100 in any of the above embodiments.

[0133] As Fig.16 shown, the control method includes:

[0134] S01: Obtain an unlocking instruction.

[0135] It should be noted that the unlocking instruction includes pressing an operation button, etc., which is not limited herein.

[0136] S02: Control the active member 31 to be energized according to the unlocking instruction so that the active member 31 drives the sliding block 33 to slide from the locked position towards the unlocked position.

[0137] Combined with Figure 2 , in the actual door opening operation: The user first presses the operation button to issue an unlocking instruction. After the door lock structure 100 obtains the unlocking instruction, it controls the active member 31 to be energized according to the unlocking instruction to drive the sliding block 33 to slide from the locked position towards the unlocked position, so that the engaging portion 11 and the limiting portion 21 can be relatively separated. Then the user can press the mechanical button, so that the transmission structure drives the engaging handle 10 to move in the first direction (such as Figure 2 the vertical direction in Figure 2 ) away from the limiting portion 21 relative to the locking bracket 20, so that the engaging portion 11 and the limiting portion 21 are separated. Then the user pulls the engaging handle 10 in the second direction (such as

[0138] the horizontal direction in Figure 2 ) away from the box body to open the door body. Figure 2 In the actual door closing operation: The user can first push the engaging handle 10 to move in the second direction (such as

[0139] the horizontal direction in Fig.16 ) towards the locking bracket 20 relative to the locking bracket 20, so that the engaging portion 11 can extend into the locking bracket 20 along the upper side of the limiting portion 21. Then control the engaging portion 11 to move in the first direction (such as

[0140] the vertical direction in

[0141] ) towards the limiting portion 21, so that the engaging portion 11 and the limiting portion 21 are in limiting cooperation to close the door body. That is to say, after controlling the active member 31 to be energized according to the unlocking instruction so that the active member 31 drives the sliding block 33 to slide from the locked position towards the unlocked position, and after powering on the active member 31 for a set duration, for example, 10s, power off the active member 31, so that the sliding block 33 automatically resets to the locked position under the elastic force of the reset member 32. It should be noted that the above 10s is only for illustrative purposes and does not represent a limitation thereto.

[0142] Among them, after the door is opened and regardless of whether the door body is closed or not, after the driving member 31 is powered for a set time, the driving member 31 is powered off so that the sliding block 33 returns to the locking position under the elastic force, thereby realizing the automatic reset of the sliding block 33. And after the sliding block 33 is automatically reset, or when the door lock structure 100 is powered off, the user can close the door body or forcefully open the door body without re-powering the driving member 31.
