Description

Technical Field

[0001] The present invention relates to the technical field of cooking utensils, and in particular to a locking assembly and a cooking utensil. Background Art

[0002] In the related art, the setting of the microwave oven is unreasonable. The microwave oven can be opened by lightly pulling the door. Children may easily touch the buttons or the door handle by mistake, which poses a safety hazard. Summary of the Invention

[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.

[0004] To this end, a first aspect of the present invention provides a locking assembly.

[0005] A second aspect of the present invention provides a cooking appliance.

[0006] In view of this, the first aspect of the present invention proposes a locking assembly, comprising: a base plate; a door body, located on one side of the base plate, the door body being provided with a door hook; a lock structure, arranged on the base plate, the lock structure comprising a first mating part and a second mating part, the first mating part being able to move between a first position and a second position relative to the base plate, the second mating part being able to move between a restricting position that restricts the movement of the door hook and a release position that releases the restriction on the movement of the door hook; wherein, in the first position, the first mating part restricts the second mating part from moving from the restricting position to the release position, and in the second position, the first mating part releases the restriction on the movement of the second mating part, and the second mating part can move from the restricting position to the release position.

[0007] The present invention provides a locking assembly comprising a base plate, a door body and a lock structure.

[0008] After locking the door, the first fitting restricts the movement of the second fitting in the first position. Specifically, it restricts the movement of the second fitting from the restricted position to the released position. That is, the second fitting remains in the restricted position and cannot move to the released position. When the first fitting is in the restricted position, the second fitting restricts the movement of the door hook, blocking the door from opening. At this point, even if a child pulls on the door, the door cannot be unlocked. In other words, the door and the lock structure work together to function as a child lock. When the first fitting is in the first position and engaged with the second fitting, the door cannot be opened.

[0009] When the first mating piece is in the second position, the first mating piece releases the restriction on the movement of the second mating piece, and the second mating piece can move from the restricted position to the release position. When the second mating piece moves to the release position, the restriction on the door hook can be released, and the door body can be opened. At this time, the purpose of unlocking the door body can be achieved by pulling the door body.

[0010] This setting can effectively solve the problem in related technologies that children accidentally touch the button or the door and unlock the door, so that the locking component has a two-step door opening function, which can ensure the safety and reliability of the use of cooking appliances including the locking component.

[0011] It is understood that the second engaging member is movable between a restricted position, which limits the movement of the door hook, and a release position, which releases the restriction. When the second engaging member is in any position other than the release position, the door is restricted from movement. In other words, when the second engaging member is in the restricted position and engages with the door hook, even pulling on the door will not open it. In other words, the door will not be unlocked by external force, fundamentally solving the problem of children accidentally unlocking the door by touching the button or the door.

[0012] Specifically, the lock structure is arranged on the base plate, and the door body is located on one side of the base plate. This setting can ensure the matching size of the lock structure and the door body, and then ensure the matching size of the second matching part, the first matching part and the door hook, so that the second matching part can effectively limit the movement of the door body when it is in the restricted position, providing effective and reliable structural support.

[0013] The locking assembly according to the present invention may also have the following additional technical features:

[0014] In the above technical solution, further, the substrate is provided with an opening, and the lock structure also includes: a base body, which is provided on the substrate; a first support member, which is rotatably connected to the base body, and the first matching member is provided on the first support member; a driving member, which is provided on the first support member, and the driving member extends out of the outer surface of the substrate through the opening, and the driving member is used to drive the first matching member to move between the first position and the second position.

[0015] In this technical solution, the lock structure further includes a base, a first support member, and a driver. Both the first mating member and the driver are disposed on the first support member. Because the first support member is rotationally connected to the base, when the driver drives the first support member to rotate relative to the base, the first mating member also rotates with the first support member, moving between a first position and a second position.

[0016] Specifically, the driving member extends out of the outer surface of the substrate through the opening, and an external force acts on the driving member, causing the driving member to move relative to the substrate, thereby driving the first supporting member to rotate relative to the base, thereby driving the first matching member to rotate.

[0017] It is understood that after the door is locked, the first mating member is in the first position, which restricts the movement of the second mating member, making it impossible to open the door. By toggling the driving member, the driving member drives the first support member to rotate, and the first support member rotates to drive the first mating member to move from the first position to the second position, and the second mating member can move from the restricted position to the released position, allowing the door to be opened. At this time, the door can be unlocked by pulling the door.

[0018] Specifically, the cross-sectional area of ​​the opening is larger than the cross-sectional area of ​​the driving member, thereby providing structural support for the driving member to move relative to the opening.

[0019] Specifically, one of the first support member and the base body is provided with a rotating shaft, and the other of the first support member and the base body is provided with an axial hole. The rotating shaft is rotatably connected to the axial hole to achieve the purpose of rotatably connecting the first support member and the base body.

[0020] In any of the above technical solutions, further, along the rotation direction of the first support member, a portion of the first matching member is located on one side of the driving member.

[0021] In this technical solution, by rationally configuring the mating structure of the first mating member and the driving member, a portion of the first mating member is positioned to one side of the driving member along the rotational direction of the first support member. This arrangement allows the first mating member to quickly engage or separate from the second mating member with a relatively small rotation angle of the driving member, thereby improving the convenience of operating the locking assembly.

[0022] In any of the above technical solutions, further, the lock structure further includes: a connecting structure, which is provided on the base body, and the second matching member is rotatably connected to the connecting structure.

[0023] In this technical solution, the lock structure also includes a connecting structure, which is provided on the base body, and the second mating piece is rotatably connected to the connecting structure. The second mating piece rotates relative to the connecting structure to move between a restricting position for restricting the movement of the door hook and a release position for releasing the restriction on the movement of the door hook.

[0024] In any of the above technical solutions, further, the second matching piece is provided with a stop portion, and the door hook is provided with a stop matching portion; in the first position, at least a portion of the stop portion abuts against the top of the stop matching portion, and the second matching piece abuts against the top of the first matching piece.

[0025] In this technical solution, the second mating member is provided with a stop portion, and the door hook is provided with a stop-matching portion. The second mating member uses the stop portion to limit the movement of the door hook. For example, when the second mating member is in the restricted position, at least a portion of the stop portion abuts the top of the stop-matching portion of the door hook, thereby preventing the door hook from moving upward.

[0026] In any of the above technical solutions, further, the second mating piece includes a first mating segment and a second mating segment, and the first mating segment and the second mating segment are located on both sides of the connecting structure; the weight of the first mating segment is less than the weight of the second mating segment, and the stop portion is provided on the first mating segment; wherein, in the first position, the first mating piece limits the movement of the second mating segment, and the stop portion limits the movement of the door hook.

[0027] In this technical solution, the second mating piece includes a first mating segment and a second mating segment. By reasonably setting the structure of the second mating piece and the connecting structure, the first mating segment and the second mating segment are located on both sides of the connecting structure, that is, the first mating segment is located on the first side of the connecting structure, and the second mating segment is located on the second side of the connecting structure, and the first side of the connecting structure and the second side of the connecting structure are set correspondingly.

[0028] Since the weight of the first mating segment is less than that of the second mating segment, when the first mating piece moves to the second position, that is, when the first mating piece and the second mating piece are separated, the second mating segment of the second mating piece presses the first mating segment upward under the action of gravity, so that the stop portion on the first mating segment is separated from the door hook of the door body. At this time, the door body can be opened. At this time, the purpose of unlocking the door body can be achieved by pulling the door body.

[0029] When the first mating piece moves to the first position, the first mating piece limits the second mating segment from moving in the direction of gravity, and the stop portion on the first mating segment limits the door hook from moving upward, thereby blocking the door hook and preventing the door from being opened. At this time, even if a child pulls the door, the door cannot be unlocked.

[0030] The structure of the second mating part is reasonably set up, which ensures that the second mating part can move between the restriction position for restricting the movement of the door hook and the release position for releasing the restriction on the movement of the door hook, while avoiding the material investment for resetting the second mating part, and has the advantages of easy assembly and low production cost.

[0031] In any of the above technical solutions, further, the connection structure includes: a second support member, which is arranged on the base body; a cover body, which is connected to the second support member, and the cover body and the second support member enclose an installation channel, the second matching member passes through the installation channel, and the second matching member is rotatably connected to the wall of the installation channel.

[0032] In this technical solution, the connection structure includes a second support member and a cover body, the second support member and the cover body are connected, and the second support member and the cover body cooperate to enclose a mounting channel.

[0033] The second mating member extends through the mounting channel and is rotatably connected to the wall of the mounting channel. That is, the second mating member is rotatable relative to the mounting channel. It is understood that because the second mating member extends through the mounting channel, the wall of the mounting channel limits the rotation angle of the second mating member, allowing the second mating member to effectively move between a restricted position and a released position.

[0034] Specifically, a rotating shaft is provided on one of the second mating piece and the wall of the installation channel, and an axial hole is provided on the other of the second mating piece and the wall of the installation channel. The rotating shaft and the axial hole are rotatably connected to enable the second mating piece to rotate relative to the installation channel.

[0035] Specifically, the cross-sectional area of ​​the installation channel is greater than the cross-sectional area of ​​the second fitting member, thereby providing structural support for the second fitting member to rotate relative to the installation channel.

[0036] Specifically, the second support member and the cover body are detachably connected, such as by screwing, riveting, magnetic connection, plug connection, etc. This arrangement ensures the reliability of the connection between the second support member and the cover body while facilitating the assembly and maintenance of the second support member, the second matching member and the cover body.

[0037] In any of the above technical solutions, further, the connecting structure is provided with a first limiting rib and a second limiting rib, the first limiting rib and the second limiting rib are located on the same side of the second mating part, and the first limiting rib and the second limiting rib are both used to limit the rotation angle of the second mating part; wherein, the distance from the first limiting rib to the top wall of the connecting structure is smaller than the distance from the second limiting rib to the top wall of the connecting structure.

[0038] In this technical solution, the second support member is provided with a first limiting rib and a second limiting rib. By rationally arranging the structures of the first limiting rib, the second limiting rib, and the second mating member, the first limiting rib and the second limiting rib are located on the same side of the second mating member, and the distance from the first limiting rib to the top wall of the connecting structure is shorter than the distance from the second limiting rib to the top wall of the connecting structure. In other words, along the height direction of the second support member, a portion of the first limiting rib is located at a higher height than the second limiting member.

[0039] Specifically, when the second matching piece is located at the restricted position, the first limiting rib can limit the rotation angle of the second matching piece so that the second matching piece will not continue to rotate counterclockwise, thereby ensuring the matching size of the second matching piece and the door hook.

[0040] Specifically, when the second matching piece is in the release position, the second limiting rib can limit the rotation angle of the second matching piece, so that the second matching piece will not continue to rotate in the clockwise direction, thereby ensuring the matching size of the second matching piece and the door hook.

[0041] Specifically, the first limiting rib and the second limiting rib are both located at the bottom of the second matching piece.

[0042] In any of the above technical solutions, further, the connecting structure is rotationally connected to the base body; the lock structure also includes a reset member, which is connected to the base body and the connecting structure, and is used to drive the second matching member to return from the release position to the restricted position.

[0043] In this technical solution, the lock structure further comprises a reset member connected to the base body and the connection structure, and the reset member can restore the second matching member from the release position to the restricted position.

[0044] That is, the base and the connecting structure are both connected to the reset member, and the base and the connecting structure serve as a carrier to support and fix the reset member. The reset member provides dynamic support for the second mating member to return from the release position to the restrained position, thereby providing structural support for the second mating member to move between the restrained position and the released position.

[0045] Specifically, when the door is closed, the door hook contacts the second matching piece and pushes the second matching piece. Since the connecting structure and the base are rotatably connected, the connecting structure rotates under the action of external force to drive the second matching piece to move from the restricted position to the released position.

[0046] After the door is closed, the second matching member returns from the release position to the restriction position under the action of the reset member to limit the door hook.

[0047] That is, when the door is closed, the front end of the door hook pushes against the second matching piece to move it backward. When the door is completely closed, the door hook enters the lock slot of the base plate. At this time, the second matching piece, which was moved backward by the door hook during the closing process, will move forward again due to the reset function of the reset piece until it moves to the door hook, thus achieving the function of limiting the door hook. This is the process of automatic locking after closing the door. This setting makes the lock structure have the function of automatic locking, enriching the use function and performance of the product.

[0048] Specifically, the reset element includes a tension spring.

[0049] In any of the above technical solutions, further, the seat body is provided with a stopper, the connecting structure is located between the stopper and the reset member, and the stopper is used to limit the rotation angle of the connecting structure.

[0050] In this technical solution, the base body is provided with a stopper. Since the connecting structure is located between the stopper and the reset member, that is, the stopper can limit the rotation angle of the connecting structure when the second mating member is in the restricted position, so that the connecting structure will not continue to rotate, thereby ensuring the matching size of the second mating member and the door hook.

[0051] In any of the above technical solutions, the lock structure further includes an elastic member; when the driving member is located in the first area, the elastic member can drive the first matching member to reset from the second position to the first position; when the driving member is located in the second area, the elastic member can limit the first matching member to the second position.

[0052] In this technical solution, the lock structure also includes an elastic member. When the driving member is located in the first area, the elastic member can drive the first matching member to return from the second position to the first position. That is, the elastic member provides power support for the first matching member to return from the second position to the first position, thereby providing structural protection for the first matching member to move between the first position and the second position.

[0053] Specifically, when the external force acting on the driving member is removed and the driving member is located in the first area, the elastic member drives the first matching member to return from the second position to the first position to limit the second matching member.

[0054] Furthermore, when the driver is in the second zone, the elastic member can restrain the first mating member in the second position. In other words, when the user no longer needs to use the child lock function, the driver moves to the second zone, disabling the second mating member. This configuration can meet the diverse needs of users and enhance the product's usability and functionality.

[0055] In any of the above technical solutions, further, the base body is provided with a first connecting part, the first support member is provided with a second connecting part, and the elastic member connects the first connecting part and the second connecting part; in the first area, the connecting line passing through the center of the first connecting part and the center of the second connecting part is located on the first side of the rotation center of the first support member; in the second area, the connecting line passing through the center of the first connecting part and the center of the second connecting part is located on the second side of the rotation center of the first support member; or in the second area, the center of the first connecting part, the center of the second connecting part and the rotation center of the first support member are collinear.

[0056] In this technical solution, the base body is provided with a first connecting portion, the first support member is provided with a second connecting portion, and the elastic member connects the first connecting portion and the second connecting portion. When the elastic member connects the first connecting portion and the second connecting portion, the elastic member, the first connecting portion, and the second connecting portion cooperate to provide effective and reliable structural support, enabling the elastic member to drive the first mating member from the second position to return to the first position when the driving member is in the first region, and to retain the first mating member in the second position when the driving member is in the second region.

[0057] Specifically, the first connecting portion includes a first connecting column, and the second connecting portion includes a second connecting column.

[0058] Specifically, a first side of the rotation center of the first support member and a second side of the rotation center of the first support member are arranged opposite to each other.

[0059] In any of the above technical solutions, further, the first support member is provided with an avoidance notch, the second connecting portion is located at the avoidance notch, and the avoidance notch is used to avoid the elastic member when the driving member moves.

[0060] In this technical solution, the first support member is provided with an avoidance notch, and the second connecting part is located at the avoidance notch. The avoidance notch has the function of avoiding the elastic member, so that when the driving member moves, the first support member will not interfere with the elastic member, thereby ensuring the use function of the elastic member.

[0061] In any of the above technical solutions, further, the lock structure also includes a convex portion, the convex portion connects the first support member and the driving member, and the convex portion is located on one side of the avoidance gap.

[0062] In this technical solution, the lock structure further includes a protrusion, and the protrusion connects the first support member and the driving member. The protrusion has the function of strengthening the connection structure between the first support member and the driving member, preventing the locking component from deforming, and ensuring the matching size of the product.

[0063] In addition, the convex portion is located on a side of the avoidance notch away from the first connecting portion, and the convex portion will not interfere with the elastic member.

[0064] Specifically, the elastic member includes a tension spring.

[0065] In any of the above technical solutions, further, the seat body is provided with a first limiting member, and the first limiting member is used to limit the rotation angle of the first support member.

[0066] In this technical solution, the seat body is provided with a first limiting member, and the first limiting member is used to limit the rotation angle of the first support member.

[0067] Specifically, in the first position, the first limiting member can limit the rotation angle of the first supporting member to ensure that the first matching member and the second matching member abut against each other.

[0068] Specifically, in the second position, the second limiting member can limit the rotation angle of the first supporting member to ensure that the first matching member is separated from the second matching member.

[0069] In any of the above technical solutions, further, a portion of the peripheral side wall of the seat body is recessed toward the middle of the seat body to form a first limiting member, the first limiting member includes a first limiting wall and a second limiting wall that are relatively arranged, and the first support member is located between the first limiting wall and the second limiting wall; wherein, a portion of the driving member protrudes out of the peripheral side wall of the seat body through the first limiting member.

[0070] In this technical solution, a portion of the peripheral side wall of the seat body is recessed toward the middle of the seat body to form a first limiting member, that is, the first limiting member is a groove structure. Specifically, the first limiting member includes a first limiting wall and a second limiting wall, and the first limiting wall and the second limiting wall are arranged opposite to each other.

[0071] By rationally arranging the matching structure of the first limiting wall, the second limiting wall, the first support member, and the driving member, the first support member is positioned between the first limiting wall and the second limiting wall, and a portion of the driving member protrudes out of the peripheral side wall of the base body through the first limiting wall. When the driving member moves to a preset position, the first limiting wall or the second limiting wall blocks the driving member, thereby limiting the rotation angle of the driving member, and thus limiting the rotation angle of the first matching member. This arrangement rationally utilizes the existing structure of the base body, has a good limiting effect, and has the advantages of simple processing and low production cost.

[0072] In any of the above technical solutions, further, the base body is also provided with a second limiting member; the lock structure also includes a positioning plate, the positioning plate is connected to the first support member and the driving member, and the second limiting member is used to limit the positioning plate along the height direction of the door body.

[0073] In this technical solution, the base is further provided with a second stopper, and the lock structure also includes a positioning plate. The second stopper cooperates with the positioning plate to limit the first mating member along the height direction of the door body. This arrangement effectively prevents displacement of the first mating member and ensures that the matching dimensions of the first and second mating members provide effective structural support.

[0074] Specifically, the first limiting member and the second limiting member cooperate to limit the first matching member from multiple directions and multiple angles, thereby ensuring the stability and reliability of the operation of the locking assembly.

[0075] In any of the above technical solutions, further, the second limiting member includes a limiting groove, and the positioning plate can be inserted into the limiting groove.

[0076] In this technical solution, the second limiting member includes a limiting groove into which the positioning plate can be inserted. The groove wall of the limiting groove has a limiting effect on the positioning plate located therein, thereby limiting the first matching member along the height direction of the door body. This arrangement ensures the effectiveness and feasibility of limiting the first matching member while having the advantages of simple structure, easy processing and low production cost.

[0077] Specifically, the limiting groove is provided on one of the first limiting wall and the second limiting wall of the first limiting member.

[0078] A second aspect of the present invention provides a cooking appliance comprising: a box structure having a cooking cavity; and a locking assembly as in any technical solution of the first aspect, wherein a door is openably connected to the box structure.

[0079] Since the cooking utensil provided by the present invention includes the locking assembly according to any one of the technical solutions in the first aspect, the cooking utensil has all the beneficial effects of the locking assembly.

[0080] In the above technical solution, further, the box structure includes: a cavity body, which forms a cooking cavity; an outer shell, which covers at least a part of the cavity body, and the outer shell includes a top plate, a side plate and a back plate; a control panel, wherein the control panel, the top plate, the side plate, the back plate, the base plate and the cavity wall of the cavity body enclose an electrical cavity, and a lock structure is provided in the electrical cavity.

[0081] In this technical solution, the box structure includes a cavity body, an outer shell and a control panel. The outer shell covers at least a portion of the cavity body, and the outer shell includes a top plate, side plates and a back plate.

[0082] Specifically, the control panel, top panel, side panels, back panel, base panel, and cavity wall of the cavity body enclose an electrical chamber. The lock structure is located in the electrical chamber, and the base panel forms a portion of the wall surface of the electrical chamber. The housing, control panel, and base panel protect the lock structure located in the electrical chamber.

[0083] It can be understood that the cavity body forms a cooking cavity, and when the door body is unlocked, food can be placed into the cooking cavity and taken out of the cooking cavity.

[0084] In any of the above technical solutions, further, the lock structure is located on the back of the control panel, and the base plate is connected to the bottom of the cavity body.

[0085] In this technical solution, the positional relationship between the control panel and the lock structure is further defined. Specifically, the lock structure is located on the back of the control panel, and the base plate is connected to the bottom of the cavity body.

DETAILED DESCRIPTION

[0133] In order to more clearly understand the above-mentioned objects, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments of the present application and the features therein can be combined with each other.

[0134] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0135] Refer to the following Figures 1 to 42 A locking assembly 100 and a cooking appliance 200 are described according to some embodiments of the present invention.

[0136] Example 1:

[0137] like Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 and Figure 13 As shown, an embodiment of the first aspect of the present invention provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0138] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0139] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0140] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0141] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0142] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0143] In detail, the locking assembly 100 includes a base plate 110 , a door body 120 and a lock structure 130 .

[0144] After locking the door 120, the first engaging member 134 restricts the movement of the second engaging member 132 in the first position. Specifically, it restricts the movement of the second engaging member 132 from the restricted position to the released position. That is, the second engaging member 132 remains in the restricted position and cannot move to the released position. When the first fitting is in the restricted position, the second engaging member 132 restricts the movement of the door hook 122, thereby blocking the door 120 and preventing it from being opened. At this time, even if a child pulls on the door 120, the door 120 cannot be unlocked. In other words, the door 120 and the lock structure 130 cooperate to realize the function of a child lock. When the first engaging member 134 is in the first position and engages with the second engaging member 132, the door 120 cannot be opened.

[0145] When the first mating piece 134 is in the second position, the first mating piece 134 releases the restriction on the movement of the second mating piece 132, and the second mating piece 132 can move from the restricted position to the release position. When the second mating piece 132 moves to the release position, the restriction on the door hook 122 can be released, and the door body 120 can be opened. At this time, the purpose of unlocking the door body 120 can be achieved by pulling the door body 120.

[0146] This setting can effectively solve the problem in the related art that children accidentally touch the button or the door body 120 and unlock the door body 120, so that the locking component 100 has a two-step door opening function, which can ensure the safety and reliability of the use of the cooking appliance 200 including the locking component 100.

[0147] It is understood that the second engaging member 132 is movable between a restricted position, which restricts the movement of the door hook 122, and a release position, which releases the restriction on the movement of the door hook 122. When the second engaging member 132 is in any position other than the release position, the door body 120 is in a state of restricted movement. In other words, when the second engaging member 132 is in the restricted position and engages with the door hook 122 of the door body 120, even pulling on the door body 120 will not open the door body 120. In other words, the door body 120 will not be unlocked by external force, thereby fundamentally solving the problem of children accidentally unlocking the door body 120 by touching the button or the door body 120.

[0148] Specifically, the lock structure 130 is arranged on the substrate 110, and the door body 120 is located on one side of the substrate 110. This setting can ensure the matching dimensions of the lock structure 130 and the door body 120, and then ensure the matching dimensions of the second matching component 132, the first matching component 134 and the door hook 122, so that the second matching component 132 can effectively limit the movement of the door body 120 when it is in the restricted position, providing effective and reliable structural support.

[0149] Example 2:

[0150] like Figures 1 to 12 As shown, based on Example 1, Example 2 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0151] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0152] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0153] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0154] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0155] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0156] Furthermore, if Figure 3 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 、 Figure 10 、 Figure 11 、 Figure 12 、 Figure 15 、 Figure 16 、 Figure 17 、 Figure 18 、 Figure 19 、 Figure 20 、 Figure 21 、 Figure 22 、 Figure 23 、 Figure 24 、 Figure 25 、 Figure 28 、 Figure 29 、 Figure 30 and Figure 31 As shown, the lock structure 130 further includes a base 136 , a first support member 162 and a driving member 164 .

[0157] The base 136 is disposed on the substrate 110 .

[0158] The first supporting member 162 is rotatably connected to the base 136 , and the first matching member 134 is disposed on the first supporting member 162 .

[0159] The driving member 164 is disposed on the first supporting member 162 and extends out of the outer surface of the substrate 110 through the opening. The driving member 164 is used to drive the first matching member 134 to move between the first position and the second position.

[0160] Specifically, the lock structure 130 further includes a base 136, a first support member 162, and a driver 164. The first engaging member 134 and the driver 164 are both disposed on the first support member 162. Because the first support member 162 is rotatably connected to the base 136, when the driver 164 drives the first support member 162 to rotate relative to the base 136, the first engaging member 134 also rotates with the first support member 162, moving between a first position and a second position.

[0161] Specifically, the driving member 164 extends out of the outer surface of the substrate 110 through the opening. When external force acts on the driving member 164, the driving member 164 moves relative to the substrate 110, thereby driving the first supporting member 162 to rotate relative to the base 136, thereby driving the first matching member 134 to rotate.

[0162] It is understood that after locking the door 120, the first engaging member 134 is in the first position, and the first engaging member 134 restricts the movement of the second engaging member 132. At this time, it is impossible to open the door 120. By toggling the driving member 164, the driving member 164 drives the first supporting member 162 to rotate. The first supporting member 162 rotates to drive the first engaging member 134 to move from the first position to the second position. The second engaging member 132 can move from the restricted position to the released position, and the door 120 can be opened. At this time, the door 120 can be unlocked by pulling the door 120.

[0163] Specifically, the cross-sectional area of ​​the opening is larger than the cross-sectional area of ​​the driving member 164 , thereby providing structural support for the driving member 164 to move relative to the opening.

[0164] Specifically, one of the first support member 162 and the seat body 136 is provided with a rotating shaft, and the other of the first support member 162 and the seat body 136 is provided with an axial hole, and the rotating shaft is rotatably connected to the axial hole to meet the purpose of rotatably connecting the first support member 162 and the seat body 136.

[0165] Furthermore, if Figure 28 and Figure 31 As shown, along the rotation direction of the first support member 162 , a portion of the first matching member 134 is located on one side of the driving member 164 .

[0166] By properly configuring the mating structure of the first mating member 134 and the driving member 164, a portion of the first mating member 134 is positioned to one side of the driving member 164 along the rotational direction of the first support member 162. This arrangement allows the first mating member 134 to quickly engage or separate from the second mating member 132 by rotating the driving member 164 at a relatively small angle, thereby enhancing the convenience of operating the locking assembly 100.

[0167] Example 3:

[0168] like Figures 1 to 12 As shown, based on Example 1 or Example 2, Example 3 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0169] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0170] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0171] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0172] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0173] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0174] Furthermore, if Figure 3 、 Figure 5 、 Figure 6 、 Figure 9 、 Figure 11 and Figure 18 As shown, the lock structure 130 further includes a connecting structure 138 disposed on the base 136 , and the second engaging member 132 is rotatably connected to the connecting structure 138 .

[0175] In detail, the lock structure 130 also includes a connecting structure 138, which is provided on the base body 136, and the second matching member 132 is rotatably connected to the connecting structure 138. The second matching member 132 rotates relative to the connecting structure 138 to move between a restricting position that restricts the movement of the door hook 122 and a release position that releases the restriction on the movement of the door hook 122.

[0176] Example 4:

[0177] like Figures 1 to 12 As shown, based on Example 3, Example 4 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0178] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0179] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0180] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0181] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0182] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0183] The lock structure 130 further includes a connecting structure 138 disposed on the base 136 , and the second engaging member 132 is rotatably connected to the connecting structure 138 .

[0184] Furthermore, if Figure 18 As shown, the second fitting member 132 is provided with a stop portion 150, and the door hook 122 is provided with a stop fitting portion; in the first position, at least a portion of the stop portion 150 abuts against the top of the stop fitting portion, and the second fitting member 132 abuts against the top of the first fitting member 134.

[0185] Specifically, the second mating member 132 is provided with a stopper 150, and the door hook 122 is provided with a stopper-matching portion. The second mating member 132 uses the stopper 150 to limit the movement of the door hook 122. For example, when the second mating member 132 is in the restricted position, at least a portion of the stopper 150 abuts against the top of the stopper-matching portion of the door hook 122, thereby preventing the door hook 122 from moving upward.

[0186] Furthermore, if Figure 18 and Figure 38 As shown, the second mating member 132 includes a first mating segment 146 and a second mating segment 148 . The first mating segment 146 and the second mating segment 148 are located on both sides of the connecting structure 138 .

[0187] The weight of the first mating segment 146 is less than that of the second mating segment 148 , and the stopper 150 is provided on the first mating segment 146 . In the first position, the first mating member 134 restricts the movement of the second mating segment 148 , and the stopper 150 restricts the movement of the door hook 122 .

[0188] Among them, the second mating piece 132 includes a first mating segment 146 and a second mating segment 148. By reasonably setting the structure of the second mating piece 132 and the connecting structure 138, the first mating segment 146 and the second mating segment 148 are located on both sides of the connecting structure 138, that is, the first mating segment 146 is located on the first side of the connecting structure 138, and the second mating segment 148 is located on the second side of the connecting structure 138. The first side of the connecting structure 138 and the second side of the connecting structure 138 are correspondingly set.

[0189] Since the weight of the first mating segment 146 is less than the weight of the second mating segment 148, when the first mating piece 134 moves to the second position, that is, when the first mating piece 134 and the second mating piece 132 are separated, the second mating segment 148 of the second mating piece 132 presses the first mating segment 146 upward under the action of gravity, so that the stop portion 150 on the first mating segment 146 is separated from the door hook 122 of the door body 120. At this time, the door body 120 can be opened. At this time, the purpose of unlocking the door body 120 can be achieved by pulling the door body 120.

[0190] When the first mating piece 134 moves to the first position, the first mating piece 134 limits the second mating segment 148 from moving in the direction of gravity, and the stop portion 150 on the first mating segment 146 limits the door hook 122 from moving upward, thereby blocking the door hook 122 and preventing the door body 120 from being opened. At this time, even if a child pulls the door body 120, the door body 120 cannot be unlocked.

[0191] The structure of the second mating piece 132 is reasonably set, which ensures that the second mating piece 132 can move between a restriction position for restricting the movement of the door hook 122 and a release position for releasing the restriction on the movement of the door hook 122, while avoiding the material investment for resetting the second mating piece 132, and has the advantages of easy assembly and low production cost.

[0192] Example 5:

[0193] like Figures 1 to 12 As shown, based on Example 3, Example 5 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0194] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0195] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0196] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0197] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0198] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0199] The lock structure 130 further includes a connecting structure 138 disposed on the base 136 , and the second engaging member 132 is rotatably connected to the connecting structure 138 .

[0200] Furthermore, if Figure 17 、 Figure 18 、 Figure 19 、 Figure 22 、 Figure 23 、 Figure 24 、 Figure 26 、 Figure 27 、 Figure 34 、 Figure 35 、 Figure 39 、 Figure 40 、 Figure 41 and Figure 42 As shown, the connection structure 138 includes a second support member 140 and a cover 142 .

[0201] The second support member 140 is disposed on the base 136 .

[0202] The cover 142 is connected to the second support member 140 . The cover 142 and the second support member 140 define a mounting channel 144 . The second fitting member 132 passes through the mounting channel 144 . The second fitting member 132 is rotatably connected to the wall of the mounting channel 144 .

[0203] In detail, the connection structure 138 includes a second support member 140 and a cover body 142 . The second support member 140 and the cover body 142 are connected and cooperate with each other to enclose a mounting channel 144 .

[0204] The second mating member 132 passes through the mounting channel 144 and is rotatably connected to the wall of the mounting channel 144. That is, the second mating member 132 can rotate relative to the mounting channel 144. It will be appreciated that because the second mating member 132 passes through the mounting channel 144, the wall of the mounting channel 144 can limit the rotation angle of the second mating member 132, allowing the second mating member 132 to effectively move between a restricted position and a released position.

[0205] Specifically, a rotating shaft is provided on one of the walls of the second mating piece 132 and the installation channel 144, and an axial hole is provided on the other wall of the second mating piece 132 and the installation channel 144. The rotating shaft and the axial hole are rotatably connected to enable the second mating piece 132 to rotate relative to the installation channel 144.

[0206] Specifically, the cross-sectional area of ​​the mounting channel 144 is greater than the cross-sectional area of ​​the second mating component 132 , thereby providing structural support for the second mating component 132 to rotate relative to the mounting channel 144 .

[0207] Specifically, the second support member 140 and the cover 142 can be detachably connected, for example, by screwing, riveting, magnetic connection, plugging, etc. This arrangement ensures the reliability of the connection between the second support member 140 and the cover 142 while facilitating the assembly and maintenance of the second support member 140, the second fitting member 132, and the cover 142.

[0208] Example 6:

[0209] like Figures 1 to 12 As shown, based on Example 3, Example 6 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0210] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0211] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0212] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0213] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0214] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0215] The lock structure 130 further includes a connecting structure 138 disposed on the base 136 , and the second engaging member 132 is rotatably connected to the connecting structure 138 .

[0216] Furthermore, if Figure 40 As shown, the connection structure 138 is provided with a first limiting rib 154 and a second limiting rib 156 .

[0217] The first limiting rib 154 and the second limiting rib 156 are located on the same side of the second matching piece 132 . The first limiting rib 154 and the second limiting rib 156 are both used to limit the rotation angle of the second matching piece 132 .

[0218] The distance between the first limiting rib 154 and the top wall of the connecting structure 138 is smaller than the distance between the second limiting rib 156 and the top wall of the connecting structure 138 .

[0219] Specifically, the second support member 140 is provided with a first limiting rib 154 and a second limiting rib 156. By rationally arranging the structure of the first limiting rib 154, the second limiting rib 156, and the second mating member 132, the first limiting rib 154 and the second limiting rib 156 are located on the same side of the second mating member 132, and the distance from the first limiting rib 154 to the top wall of the connecting structure 138 is shorter than the distance from the second limiting rib 156 to the top wall of the connecting structure 138. In other words, along the height direction of the second support member 140, a portion of the first limiting rib 154 is located at a higher height than the second limiting member.

[0220] Specifically, when the second fitting member 132 is located at the restricted position, the first limiting rib 154 can limit the rotation angle of the second fitting member 132 so that the second fitting member 132 will not continue to rotate counterclockwise, thereby ensuring the matching size of the second fitting member 132 and the door hook 122.

[0221] Specifically, when the second fitting member 132 is in the release position, the second limiting rib 156 can limit the rotation angle of the second fitting member 132 so that the second fitting member 132 will not continue to rotate in the clockwise direction, thereby ensuring the matching size of the second fitting member 132 and the door hook 122.

[0222] Specifically, the first limiting rib 154 and the second limiting rib 156 are both located at the bottom of the second matching piece 132 .

[0223] Example 7:

[0224] like Figures 1 to 12 As shown, based on Example 3, Example 7 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0225] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0226] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0227] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0228] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0229] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0230] The lock structure 130 further includes a connecting structure 138 disposed on the base 136 , and the second engaging member 132 is rotatably connected to the connecting structure 138 .

[0231] Furthermore, if Figure 15 、 Figure 16 、 Figure 19 、 Figure 20 、 Figure 21 and Figure 22 As shown, the connecting structure 138 is rotatably connected to the base body 136; the lock structure 130 further includes a reset member 158, which connects the base body 136 and the connecting structure 138, and the reset member 158 is used to drive the second mating member 132 to return from the release position to the restricted position.

[0232] In detail, the lock structure 130 further includes a reset member 158, which is connected to the base 136 and the connection structure 138. The reset member 158 can restore the second engaging member 132 from the release position to the restraint position.

[0233] That is, the base 136 and the connecting structure 138 are both connected to the reset member 158, and the base 136 and the connecting structure 138 serve as a carrier to support and fix the reset member 158. The reset member 158 provides dynamic support for the second mating member 132 to return from the release position to the restrained position, thereby providing a structural guarantee for the second mating member 132 to move between the restrained position and the released position.

[0234] Specifically, when the door body 120 is closed, the door hook 122 contacts the second engaging member 132 and pushes the second engaging member 132. Since the connecting structure 138 and the base body 136 are rotatably connected, the connecting structure 138 rotates under the action of an external force, thereby driving the second engaging member 132 to move from the restricted position to the released position.

[0235] After the door is closed, the second matching member 132 returns from the release position to the restricted position under the action of the reset member 158 to limit the door hook 122 .

[0236] That is, when the door body 120 is closed, the front end of the door hook 122 of the door body 120 pushes against the second matching member 132 to move it backward. After the door body 120 is completely closed, the door hook 122 enters the lock groove of the base plate 110. At this time, the second matching member 132, which was moved backward by the action of the door hook 122 during the door closing process, will move forward again due to the reset function of the reset member 158 until it moves to the door hook 122, thus achieving the function of limiting the door hook 122. This is the process of automatic locking after closing the door body 120. This arrangement enables the lock structure 130 to have the function of automatic locking, enriching the use function and performance of the product.

[0237] Specifically, the restoring member 158 includes a tension spring.

[0238] Furthermore, if Figure 36 As shown, the seat body 136 is provided with a stopper 160 , and the connecting structure 138 is located between the stopper 160 and the reset member 158 . The stopper 160 is used to limit the rotation angle of the connecting structure 138 .

[0239] Among them, the base body 136 is provided with a stopper 160. Since the connecting structure 138 is located between the stopper 160 and the reset member 158, that is, the stopper 160 can limit the rotation angle of the connecting structure 138 when the second mating member 132 is in the restricted position, so that the connecting structure 138 will not continue to rotate, thereby ensuring the matching size of the second mating member 132 and the door hook 122.

[0240] Example 8:

[0241] like Figures 1 to 12 As shown, based on Example 2, Example 8 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0242] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0243] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0244] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0245] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0246] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0247] The lock structure 130 further includes a base 136 , a first support member 162 and a driving member 164 .

[0248] The base 136 is disposed on the substrate 110 .

[0249] The first supporting member 162 is rotatably connected to the base 136 , and the first matching member 134 is disposed on the first supporting member 162 .

[0250] The driving member 164 is disposed on the first supporting member 162 and extends out of the outer surface of the substrate 110 through the opening. The driving member 164 is used to drive the first matching member 134 to move between the first position and the second position.

[0251] Furthermore, if Figure 15 、 Figure 16 、 Figure 19 、 Figure 20 、 Figure 21 and Figure 22 As shown, the lock structure 130 also includes an elastic member 184; when the driving member 164 is located in the first area, the elastic member 184 can drive the first matching member 134 to reset from the second position to the first position; when the driving member 164 is located in the second area, the elastic member 184 can limit the first matching member 134 to the second position.

[0252] In detail, the lock structure 130 also includes an elastic member 184. When the driving member 164 is located in the first area, the elastic member 184 can drive the first mating member 134 to return from the second position to the first position. That is, the elastic member 184 provides power support for the first mating member 134 to return from the second position to the first position, thereby providing structural protection for the first mating member 134 to move between the first position and the second position.

[0253] Specifically, when the external force acting on the driving member 164 is removed and the driving member 164 is located in the first area, the elastic member 184 drives the first matching member 134 to return from the second position to the first position to limit the second matching member 132 .

[0254] Furthermore, when the driver 164 is in the second region, the elastic member 184 can retain the first mating member 134 in the second position. In other words, when the user no longer needs to use the child lock function, the driver 164 is moved to the second region, disabling the second mating member 132. This configuration can meet diverse user needs and enhance the product's usability and functionality.

[0255] Furthermore, if Figure 15 、 Figure 16 、 Figure 19 、 Figure 20 、 Figure 21 、 Figure 32 and Figure 33 As shown, the seat body 136 is provided with a first connecting portion 166, the first support member 162 is provided with a second connecting portion 168, and the elastic member 184 connects the first connecting portion 166 and the second connecting portion 168; in the first area, the connecting line passing through the center of the first connecting portion 166 and the center of the second connecting portion 168 is located on the first side of the rotation center 169 of the first support member; in the second area, the connecting line passing through the center of the first connecting portion 166 and the center of the second connecting portion 168 is located on the second side of the rotation center 169 of the first support member; or in the second area, the center of the first connecting portion 166, the center of the second connecting portion 168 and the rotation center 169 of the first support member are collinear.

[0256] The base 136 is provided with a first connecting portion 166, the first support member 162 is provided with a second connecting portion 168, and an elastic member 184 is connected to the first connecting portion 166 and the second connecting portion 168. When the elastic member 184 is connected to the first connecting portion 166 and the second connecting portion 168, the elastic member 184, the first connecting portion 166, and the second connecting portion 168 cooperate to provide effective and reliable structural support, enabling the elastic member 184 to drive the first mating member 134 from the second position to return to the first position when the driving member 164 is in the first region, and to retain the first mating member 134 in the second position when the driving member 164 is in the second region.

[0257] Specifically, the first connection portion 166 includes a first connection column, and the second connection portion 168 includes a second connection column.

[0258] Specifically, a first side of the rotation center 169 of the first support member and a second side of the rotation center 169 of the first support member are disposed opposite to each other.

[0259] Furthermore, if Figure 22 、 Figure 25 、 Figure 29 、 Figure 30 and Figure 31As shown, the first support member 162 is provided with an avoidance notch 170 , and the second connecting portion 168 is located at the avoidance notch 170 . The avoidance notch 170 is used to avoid the elastic member 184 when the driving member 164 moves.

[0260] Among them, the first support member 162 is provided with an avoidance gap 170, and the second connecting portion 168 is located at the avoidance gap 170. The avoidance gap 170 has the function of avoiding the elastic member 184, so that when the driving member 164 moves, the first support member 162 will not interfere with the elastic member 184, thereby ensuring the use function of the elastic member 184.

[0261] Furthermore, if Figure 18 、 Figure 23 、 Figure 25 、 Figure 29 、 Figure 30 and Figure 31 As shown, the lock structure 130 further includes a protrusion 172 , which connects the first support member 162 and the driving member 164 , and is located on one side of the avoidance gap 170 .

[0262] Specifically, the lock structure 130 further includes a protrusion 172 that connects the first support member 162 and the driver 164. The protrusion 172 strengthens the connection structure 138 between the first support member 162 and the driver 164, thereby preventing deformation of the locking assembly 100 and ensuring product dimensional fit.

[0263] In addition, the protrusion 172 is located on a side of the avoidance notch 170 away from the first connection portion 166 , and the protrusion 172 will not interfere with the elastic member 184 .

[0264] Specifically, the elastic member 184 includes a tension spring.

[0265] Example 9:

[0266] like Figures 1 to 12 As shown, based on Example 2, Example 9 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0267] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0268] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0269] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0270] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0271] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0272] The lock structure 130 further includes a base 136 , a first support member 162 and a driving member 164 .

[0273] The base 136 is disposed on the substrate 110 .

[0274] The first supporting member 162 is rotatably connected to the base 136 , and the first matching member 134 is disposed on the first supporting member 162 .

[0275] The driving member 164 is disposed on the first supporting member 162 and extends out of the outer surface of the substrate 110 through the opening. The driving member 164 is used to drive the first matching member 134 to move between the first position and the second position.

[0276] Furthermore, if Figure 23 、 Figure 25 and Figure 32 As shown, the seat body 136 is provided with a first limiting member 174 , and the first limiting member 174 is used to limit the rotation angle of the first supporting member 162 .

[0277] In detail, the seat body 136 is provided with a first limiting member 174 , and the first limiting member 174 is used to limit the rotation angle of the first supporting member 162 .

[0278] Specifically, when in the first position, the first limiting member 174 can limit the rotation angle of the first supporting member 162 to ensure that the first matching member 134 and the second matching member 132 abut against each other.

[0279] Specifically, in the second position, the second limiting member can limit the rotation angle of the first supporting member 162 to ensure that the first matching member 134 is separated from the second matching member 132 .

[0280] Furthermore, if Figure 23 、 Figure 25 and Figure 32 As shown, a portion of the peripheral side wall of the seat body 136 is recessed toward the middle of the seat body 136 to form a first limiting member 174, and the first limiting member 174 includes a first limiting wall 176 and a second limiting wall 178 arranged opposite to each other, and the first support member 162 is located between the first limiting wall 176 and the second limiting wall 178; wherein, a portion of the driving member 164 protrudes out of the peripheral side wall of the seat body 136 through the first limiting member 174.

[0281] A portion of the peripheral sidewall of the seat body 136 is recessed toward the center of the seat body 136 to form a first stopper 174. Specifically, the first stopper 174 includes a first stopper wall 176 and a second stopper wall 178, which are disposed opposite each other.

[0282] By rationally arranging the matching structure of the first limiting wall 176, the second limiting wall 178, the first support member 162, and the driving member 164, the first support member 162 is positioned between the first limiting wall 176 and the second limiting wall 178, and a portion of the driving member 164 protrudes out of the peripheral side wall of the seat body 136 through the first limiting wall 174. When the driving member 164 moves to a predetermined position, the first limiting wall 176 or the second limiting wall 178 blocks the driving member 164, thereby limiting the rotation angle of the driving member 164, and thus limiting the rotation angle of the first matching member 134. This arrangement rationally utilizes the existing structure of the seat body 136, has a good limiting effect, and has the advantages of simple processing and low production cost.

[0283] Example 10:

[0284] like Figures 1 to 12 As shown, based on Example 2, Example 10 provides a locking assembly 100 , which includes a base plate 110 , a door body 120 and a lock structure 130 .

[0285] The door body 120 is located on one side of the base plate 110 , and the door body 120 is provided with a door hook 122 .

[0286] The locking structure 130 is disposed on the base plate 110 . The locking structure 130 includes a first matching member 134 and a second matching member 132 .

[0287] The first fitting 134 is movable relative to the base plate 110 between a first position and a second position.

[0288] The second engaging member 132 is movable between a restricting position for restricting the movement of the door hook 122 and a releasing position for releasing the restriction on the movement of the door hook 122 .

[0289] In the first position, the first fitting member 134 restricts the second fitting member 132 from moving from the restricted position to the released position. In the second position, the first fitting member 134 releases the restriction on the movement of the second fitting member 132, and the second fitting member 132 can move from the restricted position to the released position.

[0290] The lock structure 130 further includes a base 136 , a first support member 162 and a driving member 164 .

[0291] The base 136 is disposed on the substrate 110 .

[0292] The first supporting member 162 is rotatably connected to the base 136 , and the first matching member 134 is disposed on the first supporting member 162 .

[0293] The driving member 164 is disposed on the first supporting member 162 and extends out of the outer surface of the substrate 110 through the opening. The driving member 164 is used to drive the first matching member 134 to move between the first position and the second position.

[0294] Furthermore, if Figure 21 、 Figure 23 、 Figure 25 、 Figure 28 、 Figure 29 、 Figure 30 and Figure 31 As shown, the seat body 136 is also provided with a second limiting member; the lock structure 130 also includes a positioning plate 182, the positioning plate 182 is connected to the first support member 162 and the driving member 164, and the second limiting member is used to limit the positioning plate 182 along the height direction of the door body 120.

[0295] Specifically, the base 136 is further provided with a second stopper, and the lock structure 130 further includes a positioning plate 182. The second stopper cooperates with the positioning plate 182 to limit the first mating member 134 along the height direction of the door body 120. This arrangement effectively prevents displacement of the first mating member 134 and ensures that the mating dimensions of the first mating member 134 and the second mating member 132 provide effective structural support.

[0296] Specifically, the first limiting member 174 and the second limiting member cooperate to limit the first matching member 134 from multiple directions and multiple angles, thereby ensuring the stability and reliability of the operation of the locking assembly 100.

[0297] Furthermore, specifically, the first limiting member 174 and the second limiting member cooperate to limit the first matching member 134 from multiple directions and multiple angles, thereby ensuring the stability and reliability of the operation of the locking assembly 100.

[0298] The second limiting member includes a limiting groove into which the positioning plate 182 can be inserted. The groove wall of the limiting groove has a limiting effect on the positioning plate 182 located therein, thereby limiting the first matching member 134 along the height direction of the door body 120. This arrangement ensures the effectiveness and feasibility of limiting the first matching member 134 while having the advantages of simple structure, easy processing, and low production cost.

[0299] Specifically, the limiting groove is provided on one of the first limiting wall 176 and the second limiting wall 178 of the first limiting member 174 .

[0300] Example 11:

[0301] like Figure 1As shown, an embodiment of the second aspect of the present invention provides a cooking appliance, comprising: a box structure, the box structure is provided with a cooking cavity; and a locking assembly as in any embodiment of the first aspect, the door body is connected to the box structure in an openable and closable manner.

[0302] In detail, since the cooking appliance 200 includes the locking assembly 100 according to any one of the embodiments of the first aspect, the cooking appliance 200 has all the beneficial effects of the locking assembly 100 .

[0303] Further, such as Figures 1 to 12 As shown, the box structure includes: a cavity body, which forms a cooking cavity; an outer shell, which covers at least a portion of the cavity body, and the outer shell includes a top plate, side plates and a back plate; a control panel 250, and the control panel 250, the top plate, side plates, back plate, the base plate 110 and the cavity wall of the cavity body together enclose an electrical cavity, and the lock structure 130 is located in the electrical cavity.

[0304] The box structure includes a cavity body, a shell and a control panel 250. The shell covers at least a portion of the cavity body, and the shell includes a top plate, side plates and a back plate.

[0305] Specifically, the control panel 250, top panel, side panels, back panel, base plate 110, and the cavity wall of the cavity body enclose an electrical chamber. The lock structure 130 is located within the electrical chamber, and the base plate 110 forms a portion of the wall surface of the electrical chamber. The housing, control panel 250, and base plate 110 protect the lock structure 130 within the electrical chamber.

[0306] It can be understood that the cavity body forms a cooking cavity, and when the door body 120 is unlocked, food can be placed into the cooking cavity and taken out from the cooking cavity.

[0307] In addition, the housing structure is provided with a latching slot, allowing the hook 122 of the door 120 to engage with the latching slot of the housing. In the first position, the second engaging member 132 restricts the movement of the hook 122, thereby blocking the door 120 and preventing it from opening. At this point, even if a child pulls on the door 120 assembly, the hook 122 cannot move relative to the latching slot; the hook 122 remains locked within the latching slot. In the second position, the first engaging member 134 releases the restriction on the second engaging member 132. When the second engaging member 132 moves to the release position, the restriction on the hook 122 is released. Applying an external force to the door 120 that is greater than the locking force of the hook 122 and the latching slot can unlock the door 120. In other words, the lock structure, the hook 122, and the latching slot work together to enable the cooking appliance 200 to open the door in two steps.

[0308] It is understood that the door body 120 includes a mounting body that is movably connected to the door hook 122. That is, the door hook 122 is movable relative to the mounting body. When the second engaging member 132 moves to the release position, an external force greater than the locking force between the door hook 122 and the latching slot is applied to the door body 120, causing the door hook 122 to move relative to the latching slot, thereby unlocking the door body 120.

[0309] Furthermore, if Figures 1 to 14 As shown, the lock structure 130 is located on the back of the control panel 250, and the base plate 110 is connected to the bottom of the cavity body.

[0310] The positional relationship between the control panel 250 and the locking structure 130 is further defined. Specifically, the locking structure 130 is located on the back of the control panel 250, and the base plate 110 is connected to the bottom of the cavity body.

[0311] Specifically, the cooking appliance 200 includes a microwave oven, an oven, a steamer or a steam-bake combination machine, etc., which are not listed here one by one.

[0312] Specifically, if Figure 26 、 Figure 36 、 Figure 37 、 Figure 39 、 Figure 40 、 Figure 41 and Figure 42 As shown, the seat body 136 is provided with a limiting buckle 186, and the first support rod is provided with a matching groove 188. The limiting buckle 186 and the matching groove 188 are detachably connected. In this way, the second matching component 132 can be limited in the height direction of the door body 120, providing effective and reliable structural support to ensure the matching size of the second matching component 132 and the door hook 122.

[0313] Example 12:

[0314] By rationally designing the structure of the locking assembly 100, the present invention can achieve the requirement of preventing children from opening the door, meet the requirement of two-step door opening, and simultaneously enable single-handed or two-handed operation, that is, unlocking can be done with one hand or two hands. This requires minimal changes to the entire cooking appliance 200 and has strong versatility.

[0315] Locking assembly 100 includes a reset member 158 and an elastic member 184. Both reset member 158 and elastic member 184 are always in a stretched state. Simultaneously, reset member 158 constantly forces second support member 140 to rotate counterclockwise. When driver 164 is in the first region, elastic member 184 forces first support member 162 to rotate counterclockwise. When driver 164 is in the second region, elastic member 184 forces first support member 162 to rotate clockwise.

[0316] The first engaging member 134 can block the counterclockwise downward trend of the second engaging section 148 of the second engaging member 132. Therefore, when the door is opened, the door hook is restricted from moving upward by the first engaging section 146 of the second engaging member 132, preventing the door body 120 from opening.

[0317] When the driver 164 rotates a certain angle toward the door handle, the first engaging member 134 no longer restrains the second engaging member 132. The first engaging member 134 and the second engaging member 132 separate, allowing the second engaging segment 148 of the second engaging member 132 to freely rotate. Along the length of the mounting channel 144, the second engaging segment 148 is longer than the first engaging segment 146 and weighs more than the first engaging segment 146. Therefore, the center of gravity is toward the second engaging segment 148. This allows the first engaging segment 146 to rotate upward and away from the lower door hook without obstruction, allowing the door to be opened.

[0318] The second support member 140 and the base 136 of the lock mechanism 130, which function as the position-limiting portion, are rotatable. During the door closing process, the second support member 140 can only be rotated by the lower door hook due to the action of the stopper 160 of the base 136. After the door is closed, the second support member 140 returns to its original position under the pulling force of the return member 158.

[0319] The present application solves the problem of opening the door of a cooking appliance 200 with a child lock function in a two-step door opening method. The child lock is to protect children from opening the cooking appliance 200.

[0320] The lock structure 130 is installed on the bottom plate of the cooking utensil 200, such as a microwave oven, and the microwave oven is slightly modified, and the space behind the control panel 250 is utilized. The location where the lock structure 130 is installed is the bottom plate below the control panel 250 of the microwave oven.

[0321] The microwave oven with the lock structure 130 installed can close the door normally. When closing the door, only the limiting function of the lock structure 130 works. After closing the door, the door hook 122 of the door body 120 is restricted by the lock structure 130, and the lock structure 130 can only be unlocked by moving the driving member 164.

[0322] The cooking appliance 200 also includes a first microswitch 220, a second microswitch 230 and a third microswitch 240. There are multiple door hooks 122, and the multiple door hooks 122 include an upper door hook and a lower door hook. The lower door hook cooperates with the second matching piece 132, the upper door hook cooperates with the first microswitch 220, and the second matching piece 132 cooperates with the second microswitch 230 and the third microswitch 240.

[0323] After the door is closed, the door hook triggers the first microswitch 220, and the second fitting 132 triggers the second microswitch 230 and the third microswitch 240. The first microswitch 220 is electrically connected to the microwave generator of the cooking appliance 200. The second microswitch 230 and the third microswitch 240 are electrically connected to the motor and the oven light.

[0324] Specifically, the locking assembly 100 includes a base plate 110 , a door body 120 and a lock structure 130 .

[0325] After locking the door 120, the first engaging member 134 restricts the movement of the second engaging member 132 in the first position. Specifically, it restricts the movement of the second engaging member 132 from the restricted position to the released position. That is, the second engaging member 132 remains in the restricted position and cannot move to the released position. When the first fitting is in the restricted position, the second engaging member 132 restricts the movement of the door hook 122, thereby blocking the door 120 and preventing it from being opened. At this time, even if a child pulls on the door 120, the door 120 cannot be unlocked. In other words, the door 120 and the lock structure 130 cooperate to realize the function of a child lock. When the first engaging member 134 is in the first position and engages with the second engaging member 132, the door 120 cannot be opened.

[0326] When the first mating piece 134 is in the second position, the first mating piece 134 releases the restriction on the movement of the second mating piece 132, and the second mating piece 132 can move from the restricted position to the release position. When the second mating piece 132 moves to the release position, the restriction on the door hook 122 can be released, and the door body 120 can be opened. At this time, the purpose of unlocking the door body 120 can be achieved by pulling the door body 120.

[0327] It is understood that the first position includes, but is not limited to, a point and may also be a distance. That is, the first position is defined as being within a predetermined distance range. When the first mating member 134 moves within the predetermined distance range, the first mating member 134 moves to the first position. Similarly, the second position, the restraining position, and the releasing position are not further described.

[0328] This arrangement can effectively solve the problem in the related art that a child may unlock the door 120 by mistake by touching a button or the door 120 , and can ensure the safety and reliability of the cooking appliance 200 including the locking assembly 100 .

[0329] It is understood that the second engaging member 132 is movable between a restricted position, which restricts the movement of the door hook 122, and a release position, which releases the restriction on the movement of the door hook 122. When the second engaging member 132 is in any position other than the release position, the door body 120 is in a state of restricted movement. In other words, when the second engaging member 132 is in the restricted position and engages with the door hook 122 of the door body 120, even pulling on the door body 120 will not open the door body 120. In other words, the door body 120 will not be unlocked by external force, thereby fundamentally solving the problem of children accidentally unlocking the door body 120 by touching the button or the door body 120.

[0330] Specifically, the lock structure 130 is arranged on the substrate 110, and the door body 120 is located on one side of the substrate 110. This setting can ensure the matching dimensions of the lock structure 130 and the door body 120, and then ensure the matching dimensions of the second matching component 132, the first matching component 134 and the door hook 122, so that the second matching component 132 can effectively limit the movement of the door body 120 when it is in the restricted position, providing effective and reliable structural support.
