By installing automatic locks on the door 200 and the housing 100, the automatic opening and closing of the door 200 and the housing 100 is achieved, meeting diverse user needs. It has the advantages of small footprint and simple, convenient operation, making it easy to promote and implement. The following explanation uses the automatic opening and closing of the door 200 rotatably connected to the housing 100 of a washing machine as an example.

[0054] like Figures 1-8 As shown, the automatic lock provided by this utility model includes a bolt 1, a lock body 2, a locking assembly 3, and a locking assembly 4. The bolt 1 is provided with a locking part 11 and a locking part 12. The lock body 2 is provided with a lock hole 21, which is configured to cooperate with the bolt 1. The locking assembly 3 is movably disposed on the lock body 2. When the bolt 1 is inserted into the lock hole 21, the locking assembly 3 can elastically abut against the locking part 11 to lock the bolt 1. The locking assembly 4 is movably disposed on the lock body 2. When the bolt 1 is inserted into the lock hole 21, the locking assembly 4 can move toward or away from the bolt 1 to engage or disengage the locking part 12. When the locking assembly 4 engages with the locking part 12, it can drive the bolt 1 to move, so that the locking assembly 3 can lock or unlock the bolt 1.

[0055] It needs to be explained that the locking refers to the sealed closing state between the door body 200 and the shell 100, and the door body 200 can be opened or closed by manually opening the door. The locking refers to the state of locking between the door body 200 and the shell 100, and the door body 200 is automatically locked before the washing state is opened. The locking state cannot be manually controlled. In the prior art, the locking of the washing machine is manually realized, and only the locking is automatically controlled. Therefore, if the user cannot manually open the door in time after the washing is completed, the door body 200 cannot be automatically opened. In order to realize the automatic opening and closing of the door body 200, the automatic locking and unlocking provided by the utility model can drive the locking tongue 1 to move when the locking assembly 4 is in the state of locking the locking tongue 1, so that the locking assembly 3 can lock or unlock the locking tongue 1, thereby facilitating the automatic locking and unlocking of the locking tongue 1 and realizing the automatic opening and closing of the door body 200. By providing the locking part 11 and the locking part 12 on the locking tongue 1, and correspondingly providing the locking assembly 3 and the locking assembly 4 on the lock body 2, when the locking tongue 1 is inserted into the lock hole 21 on the lock body 2, the locking assembly 3 can lock the locking tongue 1 through the locking part 11, and the locking state can manually open and close the door body 200; the locking assembly 4 can lock the locking tongue 1 through the locking part 12 and the locking part 41, and the locking assembly 3 adopts the elastic abutting mode to lock the locking tongue 1, which is convenient for manually operating the locking and unlocking of the locking tongue 1; the locking assembly 4 can move to lock and unlock the locking tongue 1, which is convenient for realizing the automatic locking control. When the locking tongue 1 is inserted into the lock hole 21, the door body 200 and the shell 100 are in contact but not completely closed and sealed. At this time, the locking assembly 4 moves towards the locking tongue 1 and can lock the locking tongue 1. Then, in the locked state, the locking assembly 4 drives the locking tongue 1 to continue moving in the insertion direction, so that the door body 200 and the shell 100 are further closed and sealed, and then the locking assembly 3 locks the locking tongue 1 at the closed and sealed position of the door body 200; at this time, the locking assembly 4 moves reversely to release the engagement with the locking tongue 1, and after the locking assembly 4 is separated from the locking tongue 1, the door body 200 and the shell 100 are locked through the locking assembly 3 and the locking tongue 1, and the door can be manually opened and closed at any time; until the washing start instruction is received, the locking assembly 4 is started again and moves towards the locking tongue 1, locks the locking tongue 1 at the closed and sealed position, realizes the locking and locking of the locking tongue 1, and the washing machine starts washing. After the washing is completed, the locking assembly 4 drives the locking tongue 1 to overcome the elastic force of the locking assembly 3, the locking tongue 1 moves and pushes the door body 200 to rotate and open, realizes the automatic opening of the door body 200 of the washing machine after washing, and solves the problem of possible secondary pollution of clothes caused by the fact that the washing machine cannot be automatically opened after washing in the prior art.

[0056] In some embodiments, the locking assembly 3 comprises a locking rod 31, a first elastic member 32 and a locking member 33. The locking rod 31 is rotatably arranged on the lock body 2 through a rotating shaft 311. The first elastic member 32 is arranged between the locking rod 31 and the lock body 2. The locking member 33 is arranged on the locking rod 31. When the locking tongue 1 is inserted into the lock hole 21, the locking member 33 elastically abuts against the locking part 11 under the action of the first elastic member 32.

[0057] As shown in Figure 4 and Figure 5 , the middle position of the lock rod 31 is provided with a through hole, the two ends of the rotating shaft 311 are fixedly connected to the lock body 2, and the rotating shaft 311 is arranged in the through hole of the lock rod 31 to achieve the rotary connection of the lock rod 31. The first elastic member 32 can be selected as a spring. The first elastic member 32 provides a rotary driving force for the lock rod 31. Under the action of the first elastic member 32, when the lock tongue 1 contacts the locking member 33, the locking member 33 can always elastically abut against the lock tongue 1 until the locking member 33 is clamped with the locking portion 11 on the lock tongue 1 to achieve the locking and fixing of the lock tongue 1. In the embodiment, the lock body 2 is provided with a limiting groove 22, the first elastic member 32 is arranged between the bottom end of the lock rod 31 and the groove wall of the limiting groove 22, and the other side of the bottom end of the lock rod 31 abuts against the opposite groove wall of the limiting groove 22 under the action of the first elastic member 32, so that the top end of the lock rod 31 always has a predetermined rotation angle. When the lock tongue 1 contacts the top end of the lock rod 31, the top end of the lock rod 31 elastically abuts against the lock tongue 1. When the top end of the lock rod 31 contacts the locking portion 11 of the lock tongue 1, the locking and positioning are achieved. It can be understood that the limiting groove 22 can prevent the lock rod 31 from excessively rotating under the action of the first elastic member 32, and the rotary driving force of the lock rod 31 is controllable. In some schemes, the locking member 33 and the first elastic member 32 are arranged on the two sides of the rotating shaft 311 to achieve the rotary elastic locking; or the first elastic member 32 is directly arranged on the back of the locking member 33 and elastically abuts against the lock body 2 to achieve the locking.

[0058] In some embodiments, among the locking portion 11 and the locking member 33, one is a protrusion and the other is a groove, and the protrusion and the groove are clamped and matched.

[0059] As shown in Figures 3-5 , the lock tongue 1 is provided with the locking portion 11 and the locking portion 12 on the two sides in the direction of being inserted into the lock hole 21, so that the locking assembly 3 and the locking assembly 4 can be arranged on the two sides of the lock hole 21, as shown in Figure 2 , to reasonably arrange and utilize the structural space of the lock body 2. For example, the locking portion 11 is a groove arranged on one side of the lock tongue 1, the locking member 33 is a protrusion arranged on the top end of the lock rod 31, and the locking member 33 and the lock rod 31 are an integral structure. During the process of manually or by the locking assembly 4 driving the lock tongue 1 to move to be inserted into or separated from the lock hole 21, the protrusion slides on the side surface of the locking portion 11 and finally clamps or separates from the groove to achieve the locking or unlocking, which is simple in structure, easy to realize, and beneficial to automatically driving the movement of the lock tongue 1 in cooperation with the locking assembly 4.

[0060] In some embodiments, the protrusion and the groove both have smooth transition surfaces.

[0061] As shown in Figures 3-5, the convex height of the convex gradually increases along the insertion locking direction of the lock tongue 1, the groove depth gradually increases along the insertion locking direction of the lock tongue 1, a slope is formed, the slope angle of the insertion locking direction of the lock tongue 1 is smaller than the slope angle of the exit unlocking direction of the lock tongue 1, thereby facilitating the reduction of the resistance when the lock tongue 1 enters, providing sufficient locking positioning clamping force, facilitating the sliding matching clamping and unclamping of the convex and the groove. The size of the convex and the groove perpendicular to the insertion direction of the lock tongue 1 is slightly smaller than the width of the lock tongue 1 or the width of the lock rod 31, so as to improve the clamping matching degree of the convex and the groove, facilitate assembly and processing, and ensure the locking effect.

[0062] In some embodiments, the insertion end of the lock tongue 1 is provided with a guide portion 13. As shown in Figure 3 , the front end of the lock tongue 1 is provided with a guide portion 13 on one side of the locking portion 11, so that the lock tongue 1 can smoothly slide and abut the lock rod 31 when inserted into the lock hole 21. The guide portion 13 is a slope structure, and the slope inclines from the locking portion 11 of the lock tongue 1 to the front end and the other side. The locking portion 11 is arranged on one end of the lock tongue 1 close to the guide portion 13, so that the lock tongue 1 is in sliding contact with the lock rod 31 under the action of the guide portion 13, and then is locked and matched with the locking piece 33.

[0063] In some embodiments, the locking assembly 4 includes a locking piece 41, which engages and meshes with the locking portion 12 to drive the lock tongue 1 to move when the locking assembly 4 moves towards the lock tongue 1 to lock the lock tongue 1.

[0064] As shown in Figure 6 , in combination Figure 2 , in this embodiment, the lock tongue 1 is inserted into the lock hole 21 along the insertion direction, and the locking piece 41 is used to drive the movement of the lock tongue 1 along the insertion direction. When the lock tongue 1 is inserted into the lock hole 21, the locking piece 41 starts to move towards the lock tongue 1, so that the locking piece 41 engages with the locking portion 12. The locking piece 41 is in transmission connection with the locking portion 12, and when the locking piece 41 rotates, it can drive the lock tongue 1 to move, thereby realizing automatic driving of locking or unlocking of the lock tongue 1, and facilitating automatic opening and closing of the door body 200. In the locked state of the lock tongue 1, the locking piece 41 can move and engage or separate from the locking portion 12 according to actual needs, realizing automatic control of locking. The meshing transmission connection mode includes but is not limited to gear transmission connection or worm and gear transmission connection.

[0065] In some embodiments, the locking portion 12 is a locking rack, and the locking piece 41 is a worm or a lead screw, which is in transmission matching connection with the locking rack.

[0066] According to the space layout in the lock body 2 and the structural requirements of the lock tongue 1, in this embodiment, the locking portion 12 on the lock tongue 1 is a locking rack processed on the body of the lock tongue 1, as shown in Figure 3, the rectangular tooth structure is adopted. Correspondingly, the locking member 41 adopts a worm or a screw, such as Figure 6 The rotation axis of the locking member 41 is parallel to the moving direction of the lock tongue 1, and the locking member 41 can drive the lock tongue 1 to move when rotating, so as to realize the automatic driving control of the locking and unlocking of the lock tongue 1, and realize the automatic opening and closing of the door.

[0067] In some embodiments, the locking assembly 4 further comprises a rotating driving member 42, and an output end of the rotating driving member 42 is connected to the locking member 41 to drive the rotation of the locking member 41.

[0068] As shown in Figure 6 The rotating driving member 42 has a rotating output end, and the rotating driving member 42 is arranged to facilitate the automatic control of the rotation of the locking member 41. According to the space layout in the lock body 2, in order to save the occupied space, a first speed reduction gear set 43 is arranged between the rotating driving member 42 and the locking member 41 to change the direction and drive. The output shaft of the rotating driving member 42 is fixedly connected to the first worm 421, the first worm 421 is perpendicular to the rotation shaft of the locking member 41, the first worm 421 is in meshing transmission connection with the input end of the first speed reduction gear set 43, and the output end of the first speed reduction gear set 43 is coaxially fixedly connected to the locking member 41. The output direction is changed, the rotating driving member 42 drives the rotation of the locking member 41, and the rotation speed of the locking member 41 can be adjusted through the first speed reduction gear set 43.

[0069] In some embodiments, the locking assembly 4 further comprises a clutch driving member 44, and the clutch driving member 44 is configured to drive the rotating driving member 42 and the locking member 41 to move towards or away from the lock tongue 1, so that the locking member 41 engages or separates from the locking portion 12.

[0070] As shown in Figure 6 The clutch driving member 44 can drive the rotating driving member 42 and the locking member 41 to move relative to the lock tongue 1 as a whole, so as to realize the control of the engagement or separation of the locking portion 12 on the lock tongue 1 and the locking member 41. When the locking portion 12 engages with the locking member 41, the locking member 41 locks the locking portion 12, and the locking tongue 1 can be driven to move to realize the automatic driving of the locking and unlocking through the locking portion 12. When the locking member 41 separates from the locking portion 12, the lock tongue 1 only elastically abuts against the locking through the locking assembly 3, and at this time, manual operation can be performed to realize the flexible operation control of the rotating opening and closing of the door body 200. The clutch driving member 44 can drive the rotating driving member 42 and the locking member 41 to move or rotate as a whole to realize the control of the engagement or separation.

[0071] In some preferred embodiments, the locking assembly 4 further comprises a swing housing 45, the swing housing 45 is arranged to rotate on the lock body 2, the clutch driving member 44 and the rotating driving member 42 are arranged on the swing housing 45, and an output end of the clutch driving member 44 is connected to the lock body 2 to drive the swing housing 45 to swing relative to the lock body 2.

[0072] As Figure 6 In this embodiment, the lock body 2 is a shell structure, and the swing shell 45 is rotatably arranged in the lock body 2. By arranging the swing shell 45, the clutch driving member 44 and the rotation driving member 42 are both mounted on the swing shell 45. Through the swing movement of the swing shell 45 relative to the lock body 2, the operation control of the engagement and disengagement of the locking member 41 and the locking portion 12 is realized. Compared with the push-pull type movement driving mode in the prior art, the swing movement mode of the locking member 41 has the advantages of small operation structure space and smooth rotation driving. The structure is simple and stable, the product has high integration degree, and the problem that the swing rack 461 is easy to be stuck in the sliding box body in the prior art is solved.

[0073] In some embodiments, the output end of the clutch driving member 44 is connected with the lock body 2 through a transmission assembly 46.

[0074] By arranging the transmission assembly 46, the internal structure space of the lock body 2 can be more reasonably utilized, and the rotation angle of the locking member 41 can be adjusted and the rotation speed can be controlled, so that the operation of the automatic lock is more stable.

[0075] In some embodiments, the transmission assembly 46 includes a swing rack 461, and the lock body 2 is provided with a swing sliding groove 14, the swing rack 461 is slidably arranged in the swing sliding groove 14, and the swing rack 461 and the swing sliding groove 14 are in elastic abutment.

[0076] As Figure 6 and Figure 7 shown, the lock body 2 is provided with a swing sliding groove 14, and the swing rack 461 is slidably arranged in the swing sliding groove 14. When the clutch driving member 44 drives the swing rack 461, the swing rack 461 slides in the swing sliding groove 14. The swing sliding groove 14 can limit the sliding displacement of the swing rack 461, thereby realizing the control of the swing angle of the locking member 41, preventing the swing shell 45 from swinging excessively, and facilitating the improvement of the swing efficiency of the swing shell 45. The swing rack 461 and the swing sliding groove 14 are in elastic abutment, so that the swing shell 45 has an elastic abutment force between the swing shell 45 and the lock body 2 during the swing movement. When the swing shell 45 drives the locking member 41 to swing towards the locking portion 12, the elastic force causes the locking member 41 and the locking portion 12 to be in elastic abutment, which facilitates the rapid engagement of the locking member 41 and the locking portion 12.

[0077] In some embodiments, a second elastic member 462 is arranged between the swing sliding groove 14 and the swing rack 461. When the locking member 41 engages with the locking portion 12, the second elastic member 462 is in a compressed state.
