[0048] The embodiments of the present application will be further described below in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0049] In the description of the embodiments of the present application, it should be noted that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the embodiments of the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as limiting the embodiments of the present application. In addition, the terms "first", "second", "third" are only for the purpose of description, and cannot be understood as indicating or implying relative importance.

[0050] The embodiments of the present application provide a laundry treating apparatus, please refer to Figure 1 , comprising an inner drum 300, a cabinet 200 and a door device 100.

[0051] Please refer to Figure 1 , the front end of the inner drum 300 has a laundry loading opening 300a.

[0052] The inner drum 300 can hold water, that is, when the laundry treating apparatus is in the process of washing laundry, the washing water is contained in the inner drum 300, which can also be called a non-porous inner drum, which can avoid the problem that the inner and outer drums are easily contaminated in the prior art by containing water in the outer drum.

[0053] It can be understood that the inner drum 300 is provided with a drain hole, which can be controllably opened and closed. During the washing process, the drain hole is closed so that the washing water is contained in the inner drum 300; when drainage is needed, the drain hole is opened.

[0054] It is to be noted that the laundry treating apparatus drains water through the drain hole during a washing process or after the washing process, and the laundry treating apparatus can also drain water through the drain hole during a spin-drying process.

[0055] The inner tub 300 is disposed in the cabinet 200, and the cabinet 200 has an opening 200a which communicates with the laundry loading port 300a.

[0056] It is to be noted that the laundry treating apparatus can be provided with an outer tub or can not be provided with an outer tub in the embodiments of the present application.

[0057] In the embodiment provided with the outer tub, the inner tub 300 can concentrate water through the outer tub during a draining process, that is, the water in the inner tub 300 enters the outer tub through the drain hole and is discharged through the drain system of the outer tub, but the washing water does not enter the outer tub during a washing process of the inner tub 300.

[0058] In the embodiment not provided with the outer tub, the inner tub 300 can also drain water through the drain hole.

[0059] Referring to Figure 2 , the door device 100 includes an outer door assembly 2 and an inner door assembly 1.

[0060] The outer door assembly 2 is used to open or close the opening 200a.

[0061] The inner door assembly 1 is disposed on the inner side of the outer door assembly 2 and is used to open or close the laundry loading port 300a, that is, the laundry loading port 300a is sealed by the inner door assembly 1.

[0062] The state of the door device 100 includes a first state. In the first state, the inner door assembly 1 is detachably engaged on the inner tub 300 and closes the laundry loading port 300a, and can rotate with the inner tub 300. That is, in the first state, the inner door assembly 1 is separated from the outer door assembly 2, and the outer door assembly 2 does not interfere with the rotation of the inner door assembly 1, and the inner tub 300 rotates with the inner door assembly 1.

[0063] It is to be noted that since the laundry loading port 300a is sealed by the inner door assembly 1, the outer door assembly 2 does not need to be sealed when closing the opening 200a.

[0064] The laundry treating apparatus of the embodiments of the present application, when it is needed to wash laundry in the inner drum 300, the door device 100 is placed in the first state, the outer door assembly 2 closes the opening 200a, the inner door assembly 1 closes the laundry putting opening 300a, the washing water is closed in the inner drum 300 by the inner door assembly 1, and the washing water cannot flow out from the laundry putting opening 300a, thus, the door seal ring in the prior art does not need to be configured, and the problem that the door seal ring in the prior art is prone to breed bacteria is fundamentally solved. In addition, since the inner door assembly 1 rotates with the inner drum 300, the sealing between the inner door assembly 1 and the inner drum 300 is static sealing, the sealing reliability is high, and the inner door assembly 1 is also not prone to wear, and the service life of the inner door assembly 1 is improved.

[0065] The laundry treating apparatus of the embodiments of the present application, during the rotation of the inner drum 300, since the inner door assembly 1 and the outer door assembly 2 are separated from each other, the vibration of the inner drum 300 cannot be transmitted to the outer door assembly 2.

[0066] It should be noted that when the user needs to take out the laundry in the inner drum 300, the inner door assembly 1 can be removed from the inner drum 300.

[0067] For the laundry treating apparatus without the outer drum, the door device 100 of the embodiments of the present application provides a feasible sealing solution for the laundry treating apparatus without the door seal ring and the outer drum.

[0068] In some embodiments, after the outer door assembly 2 is opened, the user can manually remove the inner door assembly 1 from the inner drum 300 to take out the laundry in the inner drum 300. After the laundry is placed in the inner drum 300, the inner door assembly 1 is first engaged on the inner drum 300, and then the outer door assembly 2 is closed. That is to say, in this embodiment, the inner door assembly 1 and the outer door assembly 2 are always in a separated state, and no matter opening or closing the door, the inner door assembly 1 and the outer door assembly 2 are operated independently.

[0069] In other embodiments, the state of the door device 100 further includes a second state. In the second state, the inner door assembly 1 is engaged on the outer door assembly 2 to move with the outer door assembly 2. That is to say, in the second state, the inner door assembly 1 is separated from the inner drum 300 and engaged on the outer door assembly 2, and the outer door assembly 2 can drive the inner door assembly 1 to move along the opening direction or the closing direction when opening or closing the door.

[0070] In this embodiment, when washing laundry, the door device 100 is placed in the first state, and the inner door assembly 1 and the inner drum 300 are engaged together. When the user needs to open the door, the door device 100 is first placed in the second state, so that the inner door assembly 1 and the outer door assembly 2 are engaged together, and then the door is opened, at this time, the inner door assembly 1 and the outer door assembly 2 are opened synchronously, which is convenient for the user to put in or take out the laundry.

[0071] It is to be noted that when the door body device 100 is in the second state, the outer door assembly 2 needs to bear the weight of the inner door assembly 1.

[0072] For example, referring to Figure 8 , Figure 9 and Figure 11 , the inner cylinder 300 has a radially outwardly folded edge 301 at the front end edge 300' (refer to Figure 1 ) of the inner cylinder 300, and the front end face of the inner cylinder 300 is a smooth surface, and the side wall of the clothes throwing opening 300a is also smooth, so as to avoid scratching the clothes.

[0073] For example, referring to Figure 8 , Figure 9 and Figure 11 , the front end of the inner cylinder 300 is inwardly retracted to define the clothes throwing opening 300a.

[0074] For example, referring to Figure 4 , the inner door assembly 1 includes an inner door 10 and a first clamping mechanism for clamping the edge 301 of the inner cylinder 300. It is to be noted that when the first clamping mechanism is clamped on the edge 301 of the inner cylinder 300, the inner door assembly 1 is in a state of sealing the clothes throwing opening 300a.

[0075] Referring to Figure 7 , the outer door assembly 2 includes an outer door 20, a second clamping mechanism, and a driving mechanism 22. The second clamping mechanism drives the first clamping mechanism to release the edge 301 of the inner cylinder 300 under the action of the driving mechanism 22, and engages with the first clamping mechanism. That is, the inner door assembly 1 and the outer door assembly 2 are engaged and disengaged through the first clamping mechanism and the second clamping mechanism.

[0076] Specifically, when the second clamping mechanism disengages from the first clamping mechanism, the first clamping mechanism clamps on the edge 301 of the inner cylinder 300. During the engagement of the second clamping mechanism with the first clamping mechanism, the second clamping mechanism drives the first clamping mechanism to disengage from the edge 301 of the inner cylinder 300, and finally engages together.

[0077] The driving mode of the driving mechanism 22 is not limited, for example, in some embodiments, the driving mechanism 22 can be driven by electricity, so that full automation can be realized without the need for user intervention.

[0078] For example, in some other embodiments, the driving mechanism 22 drives the second clamping mechanism to move under the action of an external force. For example, the external force can be the force exerted by the user on the driving mechanism 22. That is, in this embodiment, the user can manually operate the driving mechanism 22 to manually control the door body device 100 to switch between the first state and the second state.

[0079] Exemplarily, a part of the driving mechanism 22 extends to the outside of the outer door 20 for a user to hold, and the user holds the part of the driving mechanism 22 extending to the outside of the outer door 20 and rotates or pushes and pulls to realize the state switching of the door body device 100.

[0080] Exemplarily, the axial distance between the inner door 10 and the outer door 20 remains unchanged when the door body device 100 switches between the first state and the second state. That is, the relative position between the outer door 20 and the inner door 10 along the axial direction does not change, so as to facilitate the design size control of the door body device 100.

[0081] It should be noted that the front end face of the inner cylinder 300 and the front sealing plate of the cabinet 200 are axially spaced apart and form a spacing space, and when the outer door assembly 2 closes the opening 200a, the first clamping mechanism and the second clamping mechanism are located in the spacing space. In the prior art, the door seal ring occupies the spacing space. In the embodiment of the present application, the first clamping mechanism and the second clamping mechanism occupy the installation position of the original door seal ring, and because the size of the cabinet and the inner cylinder 300 remains unchanged, the door body device 100 of the present application can be configured.

[0082] The specific structure of the first clamping mechanism is not limited.

[0083] Exemplarily, referring to Figure 4 , the first clamping mechanism includes a ring body assembly 12, an elastic member 13, and a plurality of clamping claws 11 arranged circumferentially along the ring body assembly 12.

[0084] The ring body assembly 12 surrounds the circumferential edge of the inner door 10, the inner door 10 closes the hollow region of the ring body assembly 12, and the ring body assembly 12 is coaxially arranged with the inner cylinder 300.

[0085] Each clamping claw 11 abuts against the rear side of the rim 301 under the action of the elastic member 13, and the ring body assembly 12 abuts against the front side of the rim 301, that is, the ring body assembly 12 and the clamping claw 11 clamp the rim 301 therebetween, and the ring body assembly 12 provides a reaction force support for the clamping claw 11. Thus, the clamping claw 11 and the ring body assembly 12 jointly limit the inner cylinder 300 in the axial and circumferential directions, so that the inner door assembly 1 does not move in the axial direction relative to the inner cylinder 300, nor does it move in the radial direction.

[0086] Specifically, after the outer door assembly 2 closes the opening 200a, the ring body assembly 12 abuts against the front side of the rim 301 to input a force to the driving mechanism 22, and the driving mechanism 22 drives the second clamping mechanism to release the ring body assembly 12 and the clamping claw 11, and the clamping claw 11 automatically abuts against the rear side of the rim 301 under the action of the elastic member 13, thereby realizing the automatic clamping of the rim 301 of the inner cylinder 300 by the inner door assembly 1.

[0087] When the washing is finished and the door needs to be opened to take out the laundry, a force is input to the driving mechanism 22, the driving mechanism 22 drives the second clamping mechanism to overcome the force of the elastic member 13 on the clamping pawl, so that the clamping pawl 11 moves a certain distance radially outward, releases the edge, and makes the second clamping mechanism engage on the ring assembly 12, after which the door body device 100 is opened outward, and the clamping pawl 11 will not interfere with the edge 301.

[0088] The movement mode of the clamping pawl 11 relative to the ring assembly 12 is not limited. For example, in some embodiments, the clamping pawl 11 is in sliding connection with the ring assembly 12, and the clamping pawl 11 slides linearly radially relative to the ring assembly 12.

[0089] In other embodiments, referring to Figure 4 and Figure 6 , the clamping pawl 11 is arranged on the radial outer side of the ring assembly 12, and the clamping pawl 11 is arranged in the front-rear direction. The clamping pawl 11 can swing in the front-rear direction relative to the ring assembly 12, and the clamping pawl 11 generally forms a lever structure, and the swing axis of the lever structure is generally perpendicular to the rotation axis of the inner drum 300. For example, when the front end of the clamping pawl 11 is tilted radially outward, the rear end of the clamping pawl 11 moves radially inward.

[0090] The elastic member 13 and the second clamping mechanism exert a torque on the clamping pawl 11 in opposite directions around the swing point.

[0091] Referring to Figure 9 , Figure 10 , Figure 11 and Figure 12 , the elastic member 13 exerts a clockwise torque on the clamping pawl 11, so that the rear end of the clamping pawl 11 can move radially inward and abut against the edge 301. The second clamping mechanism exerts a counterclockwise torque on the clamping pawl 11, and when the torque exerted by the elastic member 13 on the clamping pawl 11 is overcome, the clamping pawl 11 swings counterclockwise, the rear end of the clamping pawl 11 is tilted radially outward, so that the inner drum 300 can be separated.

[0092] In this embodiment, the swing trajectory of the rear end of the clamping pawl 11 is arc-shaped, so that even if there is a certain machining error and assembly error, by adjusting the swing stroke of the clamping pawl 11, the rear end of the clamping pawl 11 can reliably abut against the edge 301, improving the sealing reliability of the inner door assembly 1 to the laundry drop opening 300a, and reducing the precision requirements of manufacturing and assembly.

[0093] It should be noted that after the clamping pawl 11 is separated from the edge 301, the inner door assembly 1 no longer has a clamping force on the edge 301, and at this time, even if the inner drum 300 rotates, it will not interfere with the inner door assembly 1, and will not cause damage to the inner door assembly 1.

[0094] It should be noted that even if the claw 11 is disengaged from the rim 301, the ring assembly 12 and the inner door 10 can still be in contact with the front end face of the inner drum 300 as long as the outer door assembly 2 has not carried the inner door assembly 1 to open. The type of contact can be non-sealing contact or sealing contact, which is not limited herein.

[0095] For example, the second clamping assembly exerts a rearward force on the ring assembly 12 to abut the ring assembly 12 against the rim 301, and at this time, the sealing effect of the inner door assembly 1 on the laundry drop opening 300a can still be maintained.

[0096] The structure of the inner door 10 is not limited, and exemplary, please refer to Figure 4 The radially outer side of the inner door 10 has a flange 101. The middle region of the inner door 10 is convex rearward to form a basin-shaped portion, which extends into the laundry drop opening 300a.

[0097] The material of the inner door 10 is not limited, for example, glass, plastic, etc. can be used, which is convenient for the user to observe the washing objects in the inner drum.

[0098] The material of the claw 11 is not limited, which has sufficient strength and toughness. For example, the claw 11 is a sheet metal part.

[0099] The shape of the claw 11 is not limited.

[0100] Exemplary, please refer to Figure 5 The claw 11 includes a flap 111 and an ear plate 112. The rear end of the flap 111 is bent radially inward and forms a claw portion 1111, and the ear plate 112 is arranged on both sides of the flap 111 in the width direction, and the swing point of the claw 11 is located on the ear plate 112. The claw 11 abuts against the rear side of the rim 301 through the claw portion 1111.

[0101] The specific structure of the second clamping mechanism is not limited, as long as it can drive the claw 11 to swing around the swing point and can bear the weight of the inner door assembly 1.

[0102] Exemplary, please refer to Figure 7 The second clamping mechanism includes a plurality of clamping arms 21, and each clamping arm 21 surrounds the ring assembly 12. All the clamping arms 21 form a ringed space, and each clamping arm 21 can move radially so that the ringed space can be enlarged or reduced.

[0103] Please refer to Figure 9 , Figure 10 , Figure 11 and Figure 12, the other end of the clamping jaw 11 is located on the movement path of the radial inward movement of the clamping jaw 21, so as to make the other end 111 of the clamping jaw 11 disengage from the edge 301 under the action of the radial inward movement of the clamping jaw 21. When the door body device 100 is in the first state, each clamping jaw 11 is clamped on the ring body assembly 12 by each clamping jaw 21.

[0104] When it is needed to release the ring body assembly 12, each clamping jaw 21 moves radially outward, and the ring clamping space becomes larger, so that the ring body assembly 12 can be released, and the clamping jaw 21 no longer exerts force on the clamping jaw 11, and the clamping jaw 11 is clamped on the edge 301 under the action of the elastic element 13, that is, when the second clamping mechanism releases the ring body assembly 12, the clamping jaw 11 is clamped on the inner cylinder 300.

[0105] In this embodiment, since each clamping jaw 21 surrounds the ring body assembly 12, when the clamping jaw 11 releases the edge 301, the inner door assembly 1 can be prevented from falling, and the structural reliability is improved.

[0106] For example, referring to Figure 7 , the clamping jaw 21 has an arc-shaped rod body 211, and the arc-shaped rod body 211 of each clamping jaw 21 is located on the same circle and is arranged concentrically with the ring body assembly 12. When the door body device 100 is in the second state, each arc-shaped rod body 211 surrounds the circumferential surface of the ring body assembly 12. In this way, the contact length of the clamping jaw 21 and the ring body assembly 12 in the circumferential direction can be increased, and the clamping reliability is improved.

[0107] For example, referring to Figure 2 , Figure 3 , and Figure 4 , the ring body assembly 12 is provided with a ring groove 121a, and the radial outer side of the ring groove 121a is open. Referring to Figure 11 and Figure 12 , when the door body device 100 is in the second state, each arc-shaped rod body 211 is embedded in the ring groove 121a. In this embodiment, in the first state, the arc-shaped rod body 211 is constrained in the ring groove 121a in the axial direction and cannot move in the axial direction, and the clamping reliability is improved.

[0108] For example, referring to Figure 5 , the front end of the flap 111 is inclined radially outward and forms an inclined portion 1112, and the clamping jaw 21 is used to clamp the inclined portion 1112. In the case that the flap 111 swings by the same angle around the swing point, the inclined portion 112 can have a larger movement stroke, and the movement reliability is ensured; in addition, when the clamping jaw 21 clamps the clamping jaw 11 on the circumferential surface of the ring body assembly 12, the inclined portion 1112 can better fit the surface of the ring body assembly 12, which can improve the clamping reliability and will not cause plastic deformation of the flap 111.

[0109] The specific structure of the ring assembly 12 is not limited as long as it is convenient for assembling the inner door 10.

[0110] Exemplarily, referring to Figure 4 , the ring assembly 12 comprises a first ring 121 and a second ring 122 located at the rear side of the first ring 121. Referring to Figure 10 and Figure 12 , the first ring 121 and the second ring 122 clamp the flange 101 therebetween, thus facilitating the assembly of the inner door 10.

[0111] The assembly mode of the first ring 121 and the second ring 122 is not limited.

[0112] Exemplarily, the first ring 121 is provided with a plurality of first holes in the circumferential direction, and the second ring 122 is provided with a plurality of second holes in the axial direction. The screw is inserted into the first hole and the second hole in the axial direction, so as to be fastened and connected.

[0113] It should be noted that in some embodiments, the screw can be inserted through the first hole and then screwed into the second hole. In this embodiment, the first hole is a light hole, and the second hole is a threaded hole. The threaded hole can be a through hole or a blind hole. In another embodiment, the screw is inserted through the second hole from the rear to the front and then screwed into the first hole. In this embodiment, the second hole is a light hole, and the first hole is a threaded hole. The threaded hole can be a through hole or a blind hole.

[0114] It should be noted that the flange 101 will not interfere with the above-mentioned screw.

[0115] It should be noted that the joint between the rim 301 and the inner door assembly 10 needs to have appropriate sealing to prevent water leakage.

[0116] Exemplarily, in some embodiments, referring to Figure 4 , the inner door assembly 1 comprises a sealing ring 124, and the front end surface of the rim 301 is sealed and abuts against the sealing ring 124. A better waterproof sealing effect is achieved through the deformation of the sealing ring 124.

[0117] The specific structure of the sealing ring 124 is not limited as long as it can be reliably installed on the ring assembly 12 and can seal the rim 301.

[0118] Exemplarily, referring to Figure 6 , Figure 10 and Figure 12 , the radially inner surface of the second ring 122 is provided with a ring rib 1221. Referring to Figure 4 and Figure 6 , the radially inner surface of the second ring 122 is provided with a ring rib 1221.The circumferential surface of the sealing ring 124 is provided with an annular groove 124a, and the annular rib 1221 is clamped into the annular groove 124a in the radial direction. In this embodiment, the annular rib 1221 axially positions the sealing ring 124 in two directions.

[0119] It should be noted that the flange 101 of the inner door 10 and the first ring body 121, and the flange 101 and the second ring body 122 can be hard extrusion assembly, or have a elastic structure therebetween.

[0120] For example, referring to Figure 10 and Figure 12 , the rear side of the flange 101 is in contact with the sealing ring 124, and the front side of the flange 101 is in abutment with the first ring body 121. In this way, the sealing ring 124 can be reused, which on the one hand improves the sealing and waterproof performance of the flange 101 and the second ring body 122, and on the other hand, also facilitates the adjustment of the clamping force of the first ring body 121 and the second ring body 122 on the flange 101.

[0121] For example, the swing point of the clamping jaw 11 is located on the second ring body 122, that is, the clamping jaw 11 is swingably connected with the second ring body 122, the annular groove 121a is arranged on the first ring body 121, and the clamping jaw 21 clamps the first ring body 121. First, the swing point of the clamping jaw 11 is as close to the edge 301 as possible, reducing the force arm from the swing point of the clamping jaw 11 to the edge 301. In this way, under the same torque, the clamping jaw 11 can output greater force to the edge 301.

[0122] For example, referring to Figure 2 , Figure 3 and Figure 4 , the circumferential outer surface of the second ring body 122 is provided with a plurality of pairs of mounting protrusions 1222, the ear plate 112 and the turning plate 111 are located between a pair of mounting protrusions 1222, and the bolt passes through a pair of ear plates 112 and a pair of mounting protrusions 1222 to rotatably mount the clamping jaw 11 on the second ring body 122.

[0123] For example, referring to Figure 4 , the first ring body 121 is provided with an avoiding notch 121b, the avoiding notch 121b penetrates the first ring body 121 at the position behind the annular groove 121a, and the clamping jaw 11 passes through the avoiding notch 121b. The avoiding notch 121b can avoid the swing stroke of the clamping jaw 11, and can prevent the clamping jaw 11 from being plastically deformed during being pressed inward by the clamping jaw 21.

[0124] For example, referring to Figure 4The ring assembly 12 includes a limiting piece 123, which is disposed radially outside the clearance notch 121b. The limiting piece 123 is used to limit the maximum amplitude of the swing of the claw 11 in the direction of the clamping edge 301. That is, the swing stroke of the claw 11 is constrained between the limiting piece 123 and the bottom wall of the clearance notch 121b to prevent the claw 11 from swinging excessively.

[0125] The specific type of elastic element 13 is not limited; it can be a disc spring, a cylindrical spring, a torsion spring, etc.

[0126] The position of the elastic element 13 is not limited, as long as it can apply torque to the chuck 11.

[0127] For example, the elastic element 13 is disposed within the clearance notch 121b and is sandwiched between the claw 11 and the bottom wall of the clearance notch 121b.

[0128] It should be noted that the limiting piece 123 will not interfere with the movement of the clamp 21.

[0129] For example, please refer to Figure 7 The inner side of the outer door 20 is provided with multiple sliding rails extending radially. The multiple sliding rails are distributed radially. The clamp 21 slides in cooperation with the sliding rails. Each clamp 21 slides in cooperation with one sliding rail. That is to say, the movement trajectory of each clamp 21 is also distributed radially.

[0130] It should be noted that radial distribution refers to a pattern distribution in a plane, which is a trajectory shape radiating outward from the center of a circle. The trajectory shape can coincide with the radius of the circle or it can be curved.

[0131] The drive mechanism 22 drives each clamp 21 to move synchronously along the slide rail.

[0132] In this embodiment, the slide rail guides and limits the movement of the clamp 21, constraining the movement trajectory of the clamp 21.

[0133] The construction of the slide rail is not limited; for example, the cross-section can be in the shape of an "I" similar to a train track.

[0134] For example, in this embodiment of the application, the slide rail is constructed as a slide groove 20a, which facilitates processing on the outer door 20.

[0135] It should be noted that the outer door 20 can be a one-piece structure or assembled from multiple parts. For example, the outer door 20 has a double-layer structure, with the outer layer being a decorative panel and the inner layer being a mounting plate, which are fixedly connected, and the slide rail is set on the mounting plate.

[0136] The specific structure of the drive mechanism 22 is not limited.

[0137] For example, please refer toFigure 7 The driving mechanism 22 comprises a reversing element and a lever 221 arranged along the front-rear direction and capable of rotating under the action of input torque. The reversing element is arranged on the inner side of the outer door 20 and connected with the lever 221. The reversing element is in movable cooperation with each clamp 21 and is used to convert the rotation of the lever 221 into the radial linear motion of the clamp 21, that is, the clamp 21 can be driven to move radially outward and can also be driven to move radially inward. The radial position of the clamp 21 depends on the rotation angle and rotation direction of the lever 221.

[0138] When torque is input to the lever 221, the lever 221 rotates, driving the reversing element to rotate. During the rotation of the reversing element, the part in cooperation with the clamp 21 can have a displacement change in the radial direction, thereby driving the clamp 21 to move radially linearly.

[0139] For example, the lever 221 is turned by 90° in the positive direction, driving the clamp 21 to move radially outward to a specified position. The lever 221 is turned by 90° in the reverse direction, driving the clamp 21 to move radially inward to another specified position.

[0140] It can be understood that in some embodiments, the lever 221 can be input with torque in the positive direction and the reverse direction by a motor.

[0141] In other embodiments, the lever 221 can be input with torque in the positive direction and the reverse direction by a user manually. Exemplarily, the lever 221 penetrates through the outer door 20, and the outer end of the lever 221 is a holding end to be rotated under the action of external force. Specifically, the user holds the holding end to drive the lever 221 to rotate. The inner end of the lever 221 is used to drive the reversing element to rotate.

[0142] The specific structure of the reversing element is not limited.

[0143] Exemplarily, please refer to Figure 7 The reversing element comprises a rotating disc 222, and the center of the rotating disc 222 is coaxially arranged with the rotation axis of the lever 221. The rotating disc 222 is provided with a plurality of radially distributed spiral groove segments 222a. A part of the clamp 21 penetrates through the spiral groove segment 222a along the front-rear direction and can slide in the spiral groove segment 222a. During the rotation of the rotating disc 222, the part of the clamp 21 in the spiral groove segment 222a has a displacement change in the radial direction.

[0144] It should be noted that the spiral groove segment 222a refers to that in the extension direction from inside to outside with the center of the rotating disc 222 as the center, there is a displacement change in the circumferential direction and a displacement change in the radial direction.

[0145] Specifically, as the clamping 21 is in sliding fit with the slide rail, the circumferential movement of the clamping 21 is constrained by the slide rail, thus, when the rotating disc 222 rotates, the clamping 21 will not rotate with the rotating disc 222, and the groove wall of the helical groove segment 222a forces the clamping 21 to move radially.

[0146] Exemplarily, the clamping 21 comprises the above-mentioned arc-shaped rod bodies 211, the connecting rods 212, and the sliding columns 213, the sliding columns 213 are arranged in the helical groove segment 222a along the front-rear direction, the arc-shaped rod bodies 211 are arranged concentrically, and the connecting rods 212 connect the sliding columns 213 and the arc-shaped rod bodies 211. The connecting rods 212 are in sliding fit with the above-mentioned slide rail.

[0147] It can be understood that the connecting rods 212 can be bent multiple times according to the layout of the parts to avoid structural interference.
