Description

Technical Field

[0001] This application belongs to the field of electrical equipment technology, and in particular relates to a door lock and electrical equipment. Background Technology

[0002] In related technologies, electrical equipment and doors are generally equipped with door locks. When the door lock is closed, it can ensure the sealing of the door on the body and the safety of use. When it is necessary to open the door, it is usually done by pulling it by hand. Therefore, it is necessary to design door handles and other structures on the door. In order to open the door, it is necessary to design handles, which affects the aesthetics and the consistency of decoration. Summary of the Invention

[0003] This application aims to at least partially solve the technical problem of handle designs affecting the aesthetics of door surfaces. To this end, this application provides a door lock and an electrical device.

[0004] In a first aspect, this application provides a door lock, comprising: a lock body having a lock opening and a guide groove; a latch that can reciprocate within the lock body through the lock opening and can be locked within the lock body; a movable member that is detachably connected to the latch and reciprocates within the lock body under the drive of the latch; an elastic member connected between the lock body and the movable member and applying an elastic force toward the lock opening to the movable member; and an adjusting member rotatably connected to the movable member and having an adjusting portion that can move within the guide groove; wherein the guide groove has a constrained position, and when the adjusting portion moves to the constrained position, the latch is locked within the lock body; and when the adjusting portion disengages from the guide groove, the latch and the lock body are unlocked.

[0005] According to the door lock provided in this application, the latch moves within the lock body, pushing a movable component to move. This movable component then drives an adjusting component to move, causing an adjusting part on the adjusting component to move within a guide groove. When the adjusting part reaches a constrained position, it is limited, thus limiting the movable component and locking the latch within the lock body. By pushing the movable component further, the latch disengages the adjusting part from the guide groove, releasing the adjusting component from its limit. The movable component, under the action of the elastic component, moves towards the latch and pushes the latch outwards, thus unlocking the latch from the lock body. By pressing the latch and allowing it to reciprocate within the lock body, locking and unlocking can be achieved. Furthermore, under the action of the elastic component, the movable component can directly push the latch out of the lock body, allowing the door to be opened without a handle, offering greater convenience and aesthetic appeal.

[0006] According to one embodiment of this application, the guide groove includes a constraint section, the constraint section and the moving direction of the latch are arranged at an angle, and the constraint position is located within the constraint section.

[0007] According to one embodiment of this application, the projection of the constraint segment on the lock body is recessed, the opening of the recess faces away from the latch, and the bottom of the recess is configured as the constraint position.

[0008] According to one embodiment of this application, the adjusting member is connected to the movable member via a rotating shaft, the movable member is provided with a connecting hole for the rotating shaft to pass through, and the elastic member abuts against the rotating shaft;

[0009] The rotating shaft has a first plane facing the side of the latch, and the connecting hole has a second plane near the side wall of the latch. The first plane is set at an angle to the extension direction of the adjusting member to control the rotation direction of the adjusting member.

[0010] According to one embodiment of this application, a protrusion is provided on the first plane, and a groove is provided on the second plane to cooperate with the protrusion. The protrusion is provided on the side of the first plane near the inlet end of the guide groove for guiding the adjustment part, and the groove is provided on the side of the second plane near the inlet end of the guide groove.

[0011] According to one embodiment of this application, the movable member is further provided with a mounting portion, which extends from the connecting hole to the side of the movable member opposite to the latch, and a portion of the elastic member is disposed on the mounting portion.

[0012] According to one embodiment of this application, the rotating shaft and the adjusting part are located on both sides of the adjusting member.

[0013] According to one embodiment of this application, the guide groove further includes an inlet section and an outlet section, which are respectively connected to both sides of the constraint section and both extend along the moving direction of the latch.

[0014] According to one embodiment of this application, a guide portion is connected between the inlet section and the outlet section, the guide portion extending from the outlet end of the outlet section to the outlet end of the inlet section.

[0015] According to one embodiment of this application, the guide groove further includes an outlet groove segment, which is connected between the outlet segment and the constraint segment. The outlet groove segment and the constraint segment are connected at an angle, and the opening of the angle formed by the outlet groove segment and the constraint segment is oriented towards the lock opening.

[0016] According to one embodiment of this application, the latch, the movable member, and the guide groove are arranged sequentially along the moving direction of the latch.

[0017] According to one embodiment of this application, the door lock further includes a drive member, which is installed in the lock body and is used to drive the movable member to move along the movement direction of the latch.

[0018] According to one embodiment of this application, the end of the movable member away from the lock is provided with a baffle extending laterally, and the output end of the drive member is connected to the baffle.

[0019] According to one embodiment of this application, the door lock further includes: two hooks rotatably connected to the movable member, the two hooks being openable and closable, and the head of the latch being locked by the two hooks.

[0020] According to one embodiment of this application, the lock body is further provided with a passage for the latch to reciprocate. The passage includes an expansion section and a guide section arranged sequentially toward the interior of the lock body. The movable member can reciprocate within the guide section. The width of the expansion section expands sequentially along the direction close to the lock opening. The two hooks can rotate to the side wall of the expansion section to unlock the latch and the two hooks.

[0021] Secondly, embodiments of this application also provide an electrical device, including a body, a door body, and a door lock as described in any of the technical solutions in the first aspect, wherein one of the latch and the lock body is connected to the door body and the other is connected to the body.

[0022] According to the electrical device provided in this application, the latch moves within the lock body, pushing the movable part to move. The movable part then drives the adjusting part to move, causing the adjusting portion on the adjusting part to move within the guide groove. When the adjusting portion reaches the constrained position, it is limited, thus limiting the movable part as well, thereby locking the latch within the lock body. As the latch pushes the movable part to continue moving, the adjusting part disengages from the guide groove, releasing the adjusting part from its limit. Under the action of the elastic element, the movable part moves towards the latch and pushes the latch outwards, thus unlocking the latch from the lock body. By pressing the door, the latch reciprocates within the lock body, achieving both locking and unlocking. Furthermore, under the action of the elastic element, the movable part can directly push the latch out of the lock body, allowing the door to be opened without a handle, offering greater convenience and aesthetic appeal.

[0041] In related technologies, electrical equipment typically has a door lock between its body and the door. When the lock is closed, it ensures the door's sealing and operational safety. To open the door, it is usually done by pulling a handle, necessitating the design of a handle. However, this design presents a technical problem affecting aesthetics and the consistency of the overall design. This application provides a door lock that at least partially solves the problem of handles affecting the aesthetics of the door surface.

[0042] The following is combined Figures 1-13 This application is described with reference to specific embodiments:

[0043] like Figure 1 and Figure 2 As shown, this application provides a door lock 100, including a lock body 110, a latch 150, a movable part 120, an elastic part 130, and an adjusting part 140.

[0044] The lock body 110 is provided with a lock opening 113 and a guide groove 114. In some embodiments, reference... Figure 3 and Figure 4 A cavity is formed inside the lock body 110, and the lock opening 113 communicates with the cavity so that the latch 150 can be inserted.

[0045] For example, refer to Figure 1 The lock body 110 may include a housing 111 and a cover 112. The cover 112 may be placed on the housing 111 and detachably connected to the housing 111 so that the housing 111 and the cover 112 together define a cavity and facilitate the assembly of the various components inside the lock body 110.

[0046] The guide groove 114 can be disposed within the lock body 110 or can extend through the lock body 110. Exemplarily, the guide groove 114 can extend through the housing 111 or the cover 112 along its depth direction; alternatively, the guide groove 114 can also be disposed on the inner sidewall of the housing 111 or the cover 112 to improve the sealing performance of the lock body 110. In one example, such as... Figure 2 As shown, the surface of the cover 112 facing the housing 111 is provided with a plurality of protrusions 1121, and the plurality of protrusions 1121 together define the guide groove 114.

[0047] The latch 150 can reciprocate within the lock body 110 via the latch 113 and can be locked within the lock body 110. In some embodiments, reference is made to... Figure 3 and Figure 4The head of the latch 150 may be provided with a latching part. The head of the latch 150 can enter the lock body 110 through the lock opening 113 and move back and forth within the lock body 110. For example, when closing the door, the head of the latch 150 moves from the lock opening 113 into the lock body 110 and can be locked within the lock body 110 to lock the door lock 100 and close the door. When opening the door, the latch 150 is unlocked from the lock body 110, and the head of the latch 150 moves outward from the lock opening 113.

[0048] The movable member 120 and the latch 150 are detachably connected and reciprocate within the lock body 110 under the drive of the latch 150. In some embodiments, the movable member 120 is movably mounted within the lock body 110 and is detachably connected to the latch 150. After the head of the latch 150 enters the lock body 110 through the lock opening 113, the head of the latch 150 can push the movable member 120 to move, thereby driving the movable member 120 to reciprocate within the lock body 110. When the latch 150 is locked within the lock body 110, the latch 150 is connected to the movable member 120; when the latch 150 is unlocked from the lock body 110, the latch 150 is separated from the movable member 120.

[0049] The elastic element 130 is connected between the lock body 110 and the movable element 120, and applies an elastic force toward the lock opening 113 to the movable element 120. In some embodiments, the elastic element 130 applies an elastic force toward the latch 150 to the movable element 120, so that the movable element 120 tends to move and reset toward the lock opening 113. When the latch 150 is pressed to move into the lock body 110 and drive the movable element 120, the elastic force of the elastic element 130 needs to be overcome. When the latch 150 is stopped being pressed, the movable element 120 moves toward the lock opening 113 under the action of the elastic force and pushes the latch 150 out of the lock body 110.

[0050] Adjusting member 140 is rotatably connected to movable member 120 and is provided with adjusting part 143, which can move within guide groove 114. In some embodiments, the adjusting member 140 is connected to the movable member 120 so that the adjusting member 140 can reciprocate with the movable member 120, and the adjusting member 140 can also rotate relative to the movable member 120. The adjusting member 140 is provided with an adjusting part 143, which can move relative to the movable member 120 as the adjusting member 140 rotates. For example, the adjusting part 143 can be a columnar structure so that the adjusting part 143 can move in the guide groove 114 along the extension direction of the guide groove 114. During the reciprocating movement of the movable member 120 in the lock body 110, the adjusting member 140 is driven to reciprocate. Since the adjusting member 140 and the movable member 120 are rotatably connected, when the extension direction of the guide groove 114 is different from the movement direction of the movable member 120, the adjusting part 143 can also move under the guide trajectory of the guide groove 114 and drive the adjusting member 140 to rotate.

[0051] refer to Figure 6 and Figure 7 The guide groove 114 has a constrained position. When the adjusting part 143 moves to the constrained position, the latch 150 is locked in the lock body 110. When the adjusting part 143 disengages from the guide groove 114, the latch 150 and the lock body 110 are unlocked.

[0052] In some embodiments, the guide groove 114 has a constrained position. When the adjusting part 143 moves to the constrained position within the guide groove 114, the guide groove 114 can constrain the movement direction of the adjusting part 143, and this constraint is transmitted to the movable part 120 through the adjusting member 140, so that the movable part 120 is also constrained in the movement direction. It is understood that the constrained direction of the adjusting member 140 on the movable part 120 is opposite to the direction of the elastic force. Under the condition that the latch 150 does not apply a driving force to the movable part 120, the movable part 120 will not move outward under the action of the elastic force of the elastic member 130, thereby locking the latch 150 within the lock body 110. When the adjusting part 143 disengages from the guide groove 114, the adjusting part 143 disengages from the constrained position, thereby releasing the constraint of the guide groove 114 on the adjusting part 143. The movable part 120 moves outward under the action of the elastic member 130 and drives the latch 150 to pop out from the lock opening 113.

[0053] In actual implementation, such as Figure 2 As shown, Figure 2The door lock 100 is in the unlocked state, the latch 150 can be located outside the lock body 110, and the movable member 120 is in the unlocked position inside the lock body 110. During the closing process, the head of the latch 150 enters the lock body 110 from the lock opening 113 and moves inward, driving the movable member 120 to overcome the elastic force of the elastic member 130 and move away from the latch 150. During the movement, the movable member 120 drives the adjusting member 140 to move. The adjusting part 143 provided on the adjusting member 140 can enter the guide groove 114 and move along the guiding direction of the guide groove 114, causing the adjusting member 140 to rotate relative to the movable member 120. When the adjusting part 143 moves to the constrained position, the guide groove 114 constrains and limits the adjusting part 143, and then the constraining force is transmitted to the movable member 120 through the adjusting member 140. This constraining force is opposite to the elastic force, preventing the movable member 120 from moving towards the lock opening 113. Figure 5 As shown, Figure 5 When the movable part 120 of the middle door lock 100 moves to the locked position, the latch 150 is locked inside the lock body 110, the door lock 100 is locked, and the door is closed; during the process of opening the door, the movable part 120 can be driven to move by pushing the latch 150 to continue moving, thereby driving the adjusting part 143 to disengage from the constrained position. When the adjusting part 143 disengages from the guide groove 114, the constraint force of the guide groove 114 on the adjusting part 143 is released, the latch 150 is released, and the movable part 120 is reset to the unlocked position in the direction close to the lock opening 113 under the action of the elastic force of the elastic member 130, and the latch 150 that is in contact with it is ejected from the lock body 110, completing the unlocking of the door lock 100, and the door is opened under the action of the elastic force.

[0054] According to the door lock 100 provided in the embodiment of this application, the latch 150 moves within the lock body 110 to push the movable member 120 to move. The movable member 120 drives the adjusting member 140 to move, so that the adjusting part 143 on the adjusting member 140 moves within the guide groove 114. When the adjusting part 143 moves to the constrained position, the adjusting part 143 is limited, so that the movable member 120 is also limited, thereby locking the latch 150 within the lock body 110. By pushing the movable member 120 to continue moving through the latch 150, the adjusting part 143 is disengaged from the guide groove 114, the adjusting member 140 is released from its limit, and the movable member 120 moves towards the latch 150 under the action of the elastic member 130 and pushes the latch 150 to move outward from the lock body 110, thereby unlocking the latch 150 from the lock body 110. By pressing the latch 150 and moving it back and forth within the lock body 110, the latch 150 can be locked and unlocked. Under the action of the elastic element 130, the movable element 120 can directly push the latch 150 out of the lock body 110, so that the door can be opened without a handle, which is convenient to use and more aesthetically pleasing.

[0055] According to some embodiments of this application, such as Figures 2-4 , Figure 7 and Figure 8 As shown, the guide groove 114 may include a constraint section 1141, which may be arranged at an angle to the moving direction of the latch 150, and the constraint position may be located within the constraint section 1141.

[0056] In some embodiments, the moving direction of the latch 150 may be consistent with the moving direction of the movable member 120. When the adjusting part 143 moves to the restraining section 1141, the force exerted by the sidewall of the restraining section 1141 on the adjusting part 143 may form a component in the moving direction of the movable member 120, so that the restraining force on the adjusting part 143 can offset the elastic force exerted by the elastic member 130 on the movable member 120, thereby limiting the movable member 120 when the adjusting part 143 moves to the restrained position.

[0057] According to some embodiments of this application, the projection of the constraint segment 1141 on the lock body 110 can be recessed, the recessed opening can face away from the latch 150, and the bottom of the recess is configured as a constraint position.

[0058] In some embodiments, the projection of the constraint segment 1141 onto the lock body 110 can be a recessed shape with an opening facing away from the latch 150, so that after the adjusting part 143 enters the constraint segment 1141, even if the latch 150 is released, the movable member 120 will drive the adjusting part 143 to move in the direction close to the latch 150 under the action of the elastic member 130, and the adjusting part 143 can only slide along the constraint segment 1141 to the bottom of the recessed shape. The bottom of the recessed shape is configured as a constraint position. Under the condition that the adjusting part 143 slides to the bottom of the recessed shape, the constraint effect of the constraint segment 1141 on the adjusting part 143 is stable, and the adjusting part 143 is not easy to disengage from the constraint segment 1141 without external force, thereby ensuring the stable limit of the movable member 120 and the locking effect on the latch 150.

[0059] In some embodiments, such as Figures 2-4 As shown, the projection of the constraint section 1141 on the lock body 110 can be set in a V shape: the apex of the V shape is configured as the constraint position. After the adjustment part 143 enters the constraint section 1141, the latch 150 is released, and the adjustment part 143 can slide along the inclined side of the constraint section 1141 to the apex of the V shape to lock the door lock 100.

[0060] In other embodiments, the projection of the constraint segment 1141 onto the lock body 110 can be U-shaped or arc-shaped: the bottom of the U-shape or arc is configured as the constraint position, and after the adjustment part 143 enters the constraint segment 1141, the latch 150 is released, and the adjustment part 143 can slide along the arc edge of the constraint segment 1141 to the bottom position to lock the door lock 100.

[0061] According to some embodiments of this application, such as Figure 1 , Figures 3-5 As shown, the adjusting member 140 can be connected to the movable member 120 via the rotating shaft 142. The movable member 120 can be provided with a connecting hole 121 through which the rotating shaft 142 passes, and the elastic member 130 can abut against the rotating shaft 142.

[0062] In some embodiments, the adjusting member 140 may be provided with a rotating shaft 142, and the adjusting member 140 is rotatably connected to the movable member 120 by passing through the connecting hole 121 via the rotating shaft 142. Furthermore, one end of the elastic member 130 may abut against the rotating shaft 142, so that the elastic member 130 simultaneously applies an elastic force to the rotating shaft 142 and the movable member 120 in a direction close to the locking hole 113, and the adjusting member 140 may abut against the movable member 120.

[0063] refer to Figure 5 The rotating shaft 142 can be provided with a first plane 1421 on the side facing the latch 150, and the connecting hole 121 can be provided with a second plane 1211 near the side wall of the latch 150. The first plane 1421 can be set at an angle with the extension direction of the adjusting member 140 to control the rotation direction of the adjusting member 140.

[0064] In some embodiments, the rotating shaft 142 has a first plane 1421 on its side facing the latch 150, and the connecting hole 121 has a second plane 1211 in the direction close to the latch 150. When the movable member 120 is in the unlocked position, the first plane 1421 can fit with the second plane 1211. The relative position between the adjusting member 140 and the movable member 120 is the initial relative position. The first plane 1421 is set in the direction facing the latch 150, and the second plane 1211 is set in the direction away from the latch 150. The elastic member 130 applies an elastic force to the rotating shaft 142 so that the first plane 1421 tends to fit with the second plane 1211. After the adjusting member 140 rotates due to the movement of the movable member 120 and the action of the adjusting part 143, the first plane 1421 tilts along the rotation direction of the adjusting member 140 so that the first plane 1421 and the second plane 1211 are set at an angle. Under the action of the elastic member 130, the angle between the first plane 1421 and the second plane 1211 always tends to approach zero degrees, so as to control the adjusting member 140 to always have the tendency to rotate in the direction of contact between the first plane 1421 and the second plane 1211, that is, the adjusting member 140 always has the tendency to return to the initial relative position, thereby controlling the rotation direction of the adjusting member 140, and thus controlling the sliding direction of the adjusting part 143 in the guide groove 114.

[0065] By setting the first plane 1421 at an angle to the extension direction of the adjusting member 140, the adjusting member 140 is inclined under the condition that the first plane 1421 and the second plane 1211 are in contact, and the adjusting part 143 is misaligned with the constrained section 1141 in the moving direction of the moving member 120. Thus, after the adjusting part 143 enters the constrained section 1141 from the inlet end of the constrained section 1141, the adjusting part 143 always has a tendency to move towards the outlet end of the constrained section 1141 under the action of the adjusting member 140, so as to control the moving direction of the adjusting part 143 in the constrained section 1141. During the locking and unlocking process of the door lock 100, it is convenient for the adjusting part 143 to move to the constrained position and to disengage from the constrained position. The structure is simple and the operation is highly stable.

[0066] According to some embodiments of this application, such as Figure 5 As shown, a protrusion 1422 may be provided on the first plane 1421, and a groove 1212 that mates with the protrusion 1422 may be provided on the second plane 1211. The protrusion 1422 may be provided on the side of the first plane 1421 near the inlet end of the guide groove 114 for introducing the adjustment part 143, and the groove 1212 may be provided on the side of the second plane 1211 near the inlet end of the guide groove 114.

[0067] Understandably, in order for the adjustment part 143 to enter the guide groove 114, during the process of the door lock 100 from unlocking to locking, the adjustment part 140 needs to be rotated towards the inlet end of the guide groove 114 first, so that the side of the first plane 1421 near the inlet end of the guide groove 114 abuts against the second plane 1211, and the side of the first plane 1421 away from the inlet end of the guide groove 114 is raised.

[0068] In some embodiments, a protrusion 1422 is disposed on the side of the first plane 1421 near the inlet end of the guide groove 114 for introducing the adjustment part 143, and a groove 1212 is disposed on the side of the second plane 1211 near the inlet end of the guide groove 114. When the movable member 120 is in the unlocked position, the first plane 1421 and the second plane 1211 are in contact, and the protrusion 1422 extends into the groove 1212 and is configured to cooperate with the groove 1212. During the rotation of the adjustment member 140, the protrusion 1422... The bottom support of the groove 1212 and the groove 422 separates the first plane 1421 from the second plane 1211. By setting the protrusion 1422, the rotating shaft 142 is more likely to have a rotational tendency to fit the first plane 1421 and the second plane 1211 in the opposite direction. By setting the protrusion 1422 and the groove 1212, the rotation angle and range of motion of the rotating shaft 142 are limited during the rotation of the rotating shaft 142. It can also prevent the rotating shaft 142 from rotating too much and thus failing to reset.

[0069] In some embodiments, the end of the protrusion 1422 away from the first plane 1421 can be rounded, and the second plane 1211 and the sidewall of the groove 1212 can be rounded to reduce frictional loss between the rotating shaft 142 and the connecting hole 121 during the rotation process and improve the durability of the door lock 100.

[0070] According to some embodiments of this application, such as Figure 9 As shown, the movable part 120 may also be provided with a mounting part 122. The mounting part 122 can extend from the connecting hole 121 to the side of the movable part 120 away from the latch 150, and part of the elastic member 130 can be provided in the mounting part 122.

[0071] In some embodiments, the elastic member 130 is mounted by providing a mounting portion 122 to improve the stability of the connection between the elastic member 130 and the movable member 120 and the rotating shaft 142. The mounting portion 122 can extend from the connection hole 121 to the side of the movable member 120 away from the latch 150. One end of the elastic member 130 extends into the mounting portion 122 and abuts against the rotating shaft 142. The other end of the elastic member 130 is connected to the inner sidewall of the lock body 110 away from the lock opening 113 to apply an elastic force to the movable member 120 in the direction of the lock opening 113.

[0072] The mounting part 122 can be a mounting groove or a mounting hole. Taking the mounting part 122 as a mounting groove as an example, the guide groove 114 is provided on the inner side of the cover 112, the adjusting member 140 is provided between the movable member 120 and the cover 112, the mounting groove is provided on the side of the movable member 120 away from the cover 112, the movable member 120 is provided with a connecting hole 121 communicating with the mounting groove on the side near the cover 112, the adjusting member 140 is provided with a rotating shaft 142 passing through the connecting hole 121, and at least a portion of the elastic member 130 extends into the mounting groove and abuts against the rotating shaft 142.

[0073] It is understood that the elastic element 130 is compressed so that when the movable element 120 is in the unlocked position, the elastic element 130 also applies an elastic force to the rotating shaft 142, driving the adjusting element 140 to reset to the initial relative position.

[0074] According to the mounting part 122 and elastic member 130 provided in the embodiments of this application, the reset of the movable member 120 and the reset of the adjusting member 140 can be realized simultaneously with only one elastic member 130. The structure layout is simple, the space layout is optimized and the stability is high.

[0075] In the embodiments of this application, such as Figure 1 , Figures 3-5 , Figure 7 and Figure 10As shown, the elastic element 130 can be a spring. In other embodiments, the elastic element 130 can also be a sheet, an elastic rubber ring, etc., and the specific type is not limited here.

[0076] In other embodiments, the elastic element 130 may include two springs, one of which is connected between the movable element 120 and the lock body 110 to apply an elastic restoring force to the movable element 120 toward the lock opening 113; the other spring is connected between the movable element 120 and the rotating shaft 142 to apply an elastic restoring force to the rotating shaft 142 to drive the adjusting element 140 to rotate.

[0077] According to some embodiments of this application, such as Figure 1 , Figures 3-5 , Figure 7 and Figures 10-13 As shown, the rotating shaft 142 and the adjusting part 143 are located on both sides of the adjusting member 140.

[0078] In some embodiments, the adjusting member 140 may include an adjusting rod 141, a rotating shaft 142 and an adjusting part 143 may be respectively disposed at both ends of the adjusting rod 141, and the rotating shaft 142 is disposed on the side of the adjusting rod 141 facing the movable member 120, and the adjusting part 143 is disposed on the side of the adjusting rod 141 facing the guide groove 114.

[0079] The adjusting part 143 can be cylindrical, with one end connected to the adjusting rod 141 and the other end extending into the guide groove 114, so that the adjusting part 143 can slide in the guide groove 114, and the structure is simple and easy to assemble.

[0080] In some embodiments, the adjustment part 143 may be rotatably mounted on the adjustment rod 141 to further reduce frictional resistance and reduce wear during use.

[0081] According to some embodiments of this application, such as Figures 2-4 As shown, the guide groove 114 may also include an inlet section 1142 and an outlet section 1143, which are respectively connected to both sides of the constraint section 1141 and extend along the moving direction of the latch 150.

[0082] In some embodiments, the inlet section 1142, the constraint section 1141, and the outlet section 1143 are sequentially distributed along the rotation direction of the adjusting member 140, with reference to... Figure 6 , Figure 6 For the movement trajectory of the adjustment unit 143 when the moving part 120 moves from the unlocked position to the locked position, the adjustment unit 143 first enters the inlet section 1142, and then transitions from the inlet section 1142 to the constraint section 1141; Reference Figure 8 , Figure 8When the moving part 120 moves from the locked position to the unlocked position, the adjusting part 143 transitions from the restraint section 1141 to the exit section 1143 and returns to the initial relative position. (Refer to...) Figure 3 With the adjustment section 143 in its initial relative position, the adjustment section 143 is located between the constraint section 1141 and the outlet section 1143 in the rotation direction of the adjustment member 140, so that the adjustment section 143 can move along the trajectory of the inlet section 1142-constraint section 1141-outlet section 1143 under the action of the elastic member 130.

[0083] Both the inlet section 1142 and the outlet section 1143 extend along the moving direction of the latch 150. By setting the inlet section 1142 and the outlet section 1143, the range of motion of the adjustment part 143 can be limited, thereby limiting the range of rotation angle of the adjustment member 140. This avoids the adjustment member 140 from having an excessively large rotation angle, which would make it difficult for the adjustment member 140 to reset, and improves the stability of the door lock 100.

[0084] According to some embodiments of this application, such as Figures 2-4 and Figure 7 As shown, a guide 115 can be connected between the inlet section 1142 and the outlet section 1143. The guide can extend from the outlet end of the outlet section 1143 to the outlet end of the inlet section 1142.

[0085] In some embodiments, in conjunction with reference Figure 6 and Figure 8 After the adjusting part 143 slides out from the outlet end of the outlet section 1143, the movable member 120 can move to the unlocked position. The adjusting part 143 can move to the initial relative position under the action of the elastic member 130. When the door lock 100 locks again, because the adjusting part 143 is located between the outlet section 1143 and the constraint section 1141 in the rotation direction of the adjusting member 140, the adjusting part 143 needs to be guided into the outlet section 1143 first. By providing a guide, when the latch 150 pushes the movable member 120 to move away from the lock opening 113, the adjusting part 143 slides from the outlet section 1143 to the inlet section 1142 under the guidance of the guide part 115.

[0086] It is understandable that the exit end of the inlet section 1142 is the same as the inlet end of the constraint section 1141.

[0087] In some embodiments, such as Figures 2-4As shown, the guide groove 114 is defined by a plurality of protrusions 1121 provided on the inner side of the cover 112. Among them, the protrusions 1121 facing the adjustment part 143 in the moving direction of the latch 150 form a guide slope on the side facing the lock opening 113. The guide slope is inclined from the outlet section 1143 to the inlet section 1142 in a direction away from the lock opening 113, so that after the adjustment part 143 abuts against the guide slope, the guide slope can guide the adjustment part 143 to move and cause the adjustment member 140 to rotate in a direction close to the inlet section 1142.

[0088] In other embodiments, the guide portion 115 can be a guide groove; the guide groove can be inclined from the outlet section 1143 to the inlet section 1142 in a direction away from the lock opening 113. When the adjustment portion 143 starts to move from the initial relative position, it first enters the guide groove and moves towards the inlet section 1142 under the guidance of the guide groove; furthermore, the two ends of the guide groove can be connected to the outlet section 1143 and the inlet section 1142 respectively, so that the guide groove 114 and the guide groove are connected into a closed whole, and the adjustment portion always moves within the guide groove or the guide groove 114.

[0089] According to some embodiments of this application, such as Figures 2-4 As shown, the guide groove 114 may also include an outlet groove segment 1144, which can be connected between the outlet segment 1143 and the constraint segment 1141. The outlet groove segment 1144 and the constraint segment 1141 can be connected at an angle, and the opening of the angle formed by the outlet groove segment 1144 and the constraint segment 1141 can be set towards the lock opening 113.

[0090] In some embodiments, the outlet segment 1144 can be connected between the outlet segment 1143 and the constraint segment 1141, so that the adjusting part 143 enters the outlet segment 1144 first after sliding out of the constraint segment 1141. By setting the opening of the angle between the outlet segment 1144 and the constraint segment 1141 towards the locking slot 113, on the one hand, the corner of the outlet segment 1144 and the constraint segment 1141 can limit the adjustment part 143, preventing the adjustment part 143 from exceeding its range of motion. On the other hand, at the corner of the adjusting part 144, the adjustment part 143 can be limited. 3. When in the initial relative position, the adjusting part 143 and the guide groove section 1144 are directly opposite each other in the moving direction of the latch 150, so that when the latch 150 pushes the movable member 120 to move away from the lock 113, the adjusting part 143 always tends to move to the guide groove section 1144. When the adjusting part 143 is located in the guide groove section 1144, the latch 150 is released, and the movable member 120 can always move to the unlock position under the action of the elastic member 130, so that the door lock 100 is more stable in operation.

[0091] According to some embodiments of this application, such as Figure 3 , Figure 4 and Figure 7As shown, the latch 150, the movable part 120, and the guide groove 114 are arranged sequentially along the moving direction of the latch 150.

[0092] In some embodiments, the latch 150, the movable member 120, and the guide groove 114 are arranged in sequence. The guide groove 114 is located on the side of the movable member 120 away from the latch 150, so that the guide groove 114 can limit the adjustment part. The structure is simple and the working process is more stable.

[0093] According to some embodiments of this application, such as Figures 10-13 As shown, the door lock 100 may also include a drive member 160, which is installed inside the lock body 110 and is used to drive the movable member 120 to move along the movement direction of the latch 150.

[0094] In some embodiments, by providing a drive member 160 within the lock body 110, the drive member 160 can drive the movable member 120 to move along the movement direction of the latch 150. The drive member 160 can be an automatically controllable or remotely controllable component. When the door lock 100 is locked, the movable member 120 is in the locked position and the latch 150 can be moved without manual intervention. By controlling the drive member 160 to drive the movable member 120 to move away from the lock opening 113 and causing the adjusting part to slide out of the guide groove 114, the door lock 100 and the door can be automatically opened. This can be coordinated with the program settings of electrical equipment. In equipment requiring water cleaning, after cleaning, the drive member 160 can be controlled to automatically open the door, accelerating the evaporation of moisture inside the equipment. Alternatively, an opening button can be provided on the electrical equipment, and an opening command can be provided on the terminal. The opening button or the opening command can be used to send a command to the drive member 160 to achieve automatic door opening.

[0095] According to some embodiments of this application, such as Figures 10-13 As shown, the end of the movable member 120 away from the lock opening 113 may be provided with a baffle 124 extending laterally, and the output end of the drive member 160 may be connected to the baffle 124.

[0096] In some embodiments, the movable member 120 may be provided with a baffle 124 extending laterally, and the driving member 160 may be provided on the side of the movable member 120 where the baffle 124 is provided. By connecting the output end of the driving member 160 to the baffle 124, the movable member 120 can be easily driven to move without interfering with the normal arrangement of the movable member 120, the elastic member 130 and other structures.

[0097] For example, the output end of the drive member 160 is provided with a drive rod 161 that is movable along the moving direction of the latch 150. The drive rod 161 pushes the baffle 124 to move, thereby driving the movable member 120 to move. The drive member 160 can be an electric strut, a cylinder, or an electromagnetic push rod, etc., and there is no specific limitation.

[0098] According to some embodiments of this application, such as Figure 1 , Figures 3-5 , Figure 7 and Figures 10-13 As shown, the door lock 100 may also include two hooks 123, which are rotatably connected to the movable member 120. The two hooks 123 are openable and closable, and the head of the latch 150 can be locked by the two hooks 123.

[0099] In some embodiments, two hooks 123 are respectively disposed on both sides of the movable member 120 and rotatably connected to the side of the movable member 120 facing the lock opening 113. The two hooks 123 are openable and closable. When the latch 150 pushes the movable member 120 to the locked position, the two hooks 123 close inward to lock the head of the latch 150, thereby locking the door lock 100. When the movable member 120 moves towards the lock opening 113 under the elastic force of the elastic member 130 until it is unlocked, the two hooks 123 open outward to unlock the head of the latch 150, so that the movable member 120 can directly push the latch 150 out of the lock body 110, thereby unlocking the door lock 100.

[0100] According to some embodiments of this application, such as Figure 1 , Figures 3-5 , Figure 7 and Figures 10-13 As shown, the lock body 110 may also be provided with a passage 116 for the reciprocating movement of the latch 150. The passage 116 may include an expansion section 1161 and a guide section 1162 arranged sequentially into the interior of the lock body 110. The movable member 120 may reciprocate within the guide section 1162. The width of the expansion section 1161 may expand sequentially in the direction close to the lock opening 113. The two hooks 123 may rotate onto the side wall of the expansion section 1161 to unlock the latch 150 and the two hooks 123.

[0101] In some embodiments, the two hooks 123 are subjected to an elastic force in a direction away from each other. For example, a torsion spring may be provided between the hooks 123 and the movable member 120.

[0102] The lock body 110 may be provided with a passage 116 for the reciprocating movement of the latch 150 and the movable member 120. The passage 116 may be connected to the lock opening 113. The passage 116 includes an expansion section 1161 and a guide section 1162 arranged in sequence. The expansion section 1161 is connected to the lock opening 113, and the width of the expansion section 1161 can be expanded in sequence in the direction close to the lock opening 113 to form a trumpet shape. In one example, the maximum width of the expansion section 1161 is the same as the width of the lock opening 113, and the minimum width of the expansion section 1161 is the same as the width of the guide section 1162.

[0103] With the movable part 120 in the unlocked position, the two hooks 123 move away from each other under the action of elastic force and rotate to engage with the side wall of the expansion section 1161 in the width direction, thereby unlocking the head of the latch 150. With the movable part 120 in the locked position, because the width of the expansion section 1161 is reduced in the direction away from the lock opening 113, the side wall of the opening 116 pushes the two hooks 123 inward to close and lock the head of the latch 150. The structure is simple and the locking effect is stable, ensuring the stability of the door lock 100.

[0104] Based on the same inventive concept, this application also provides an electrical device, which includes a body, a door body, and a door lock 100, a latch 150, and a lock body 110 as described in any of the above technical solutions, wherein one of them is connected to the door body and the other is connected to the body.

[0105] It is understood that since the electrical equipment in this application includes the door lock 100 as described in any of the above technical solutions, the technical features and effects of the door lock 100 as described in any of the above technical solutions will not be elaborated here.

[0106] In some embodiments, the door lock 100 can be locked and unlocked by pressing the door or pressing a button on the door to move the latch 150 within the lock body 110. When unlocking, the latch 150 is ejected from the lock body 110 by the elastic element 130, thereby enabling the door of the electrical appliance to open automatically without the need for a door handle.

[0107] According to the electrical device provided in the embodiments of this application, the latch 150 moves within the lock body 110, pushing the movable member 120 to move. The movable member 120 drives the adjusting member 140 to move, so that the adjusting part 143 on the adjusting member 140 moves within the guide groove 114. When the adjusting part 143 moves to the constrained position, the adjusting part 143 is limited, so that the movable member 120 is also limited, thereby locking the latch 150 within the lock body 110. By pushing the movable member 120 to continue moving through the latch 150, the adjusting part 143 is disengaged from the guide groove 114, the adjusting member 140 is released from its limit, and the movable member 120 moves towards the latch 150 under the action of the elastic member 130, pushing the latch 150 to move outward from the lock body 110, thereby unlocking the latch 150 from the lock body 110. By pressing the door body, the latch 150 can be moved back and forth within the lock body 110, thus locking and unlocking the latch 150. Under the action of the elastic element 130, the movable element 120 can directly push the latch 150 out of the lock body 110, allowing the door to be opened without a handle, which is convenient to use and more aesthetically pleasing.

[0108] According to some embodiments of this application, the electrical appliance may include a dishwasher.

[0109] In other embodiments, the electrical equipment may also include at least one of a disinfection cabinet, a microwave oven, a refrigerator, or a water dispenser, without limitation.
