Referring to fig. 1 and 3, a flip assembly 100 is provided in accordance with an embodiment of the present application. The flip assembly 100 includes a housing 10, a cover 20, and a connector 30. The casing 10 is provided with an opening 11, and the cover plate 20 can be movably connected with the casing 10 through a connecting piece 30. Under the action of external force, the cover plate 20 can deflect relative to the housing 10 and switch between an open state of shielding the opening 11 and a buckled state of exposing the opening 11. In other words, the cover 20 can deflect relative to the housing 10 under the action of external force, and when the cover 20 shields the opening 11 of the housing 10, the cover 20 is in a buckled state; when the opening 11 of the housing 10 is exposed, the cover 20 is in an open state.

Referring also to fig. 7, the connector 30 includes a first end 36 and a second end 37 disposed opposite each other. The first end 36 is connected to the cover 20 and the second end 37 is movably connected to the housing 10. The connecting piece 30 further includes a connecting portion 34 and an abutting portion 35 (see fig. 7). The connecting portion 34 and the abutting portion 35 are located at the second end 37 and are connected together, and the extending direction of the connecting portion 34 may be perpendicular to the deflection plane of the connecting member 30. One end of the connecting portion 34 is movably connected to the housing 10, and the abutting portion 35 is configured as one end of the connecting portion 34 connected to the housing 10. For example, the housing 10 may be provided with mounting holes that mate with the connection portions 34. The housing 10 and the connector 30 are deflected relative to the housing 10 about the second end 37 of the connector 30.

When the cover plate 20 is switched from the open state of the shielding opening 11 to the closed state of the exposed opening 11, the abutting part 35 can be driven by the connecting part 34 to enable different areas of the cover plate 20 to abut against the shell 10 respectively, so that the deflection speed of the cover plate 20 is gradually slowed down.

Illustratively, when the cover 20 is switched from the snapped state (example shown in fig. 1) to the open state (example shown in fig. 3), the cover 20 may rotate clockwise relative to the housing 10 about the abutment 35 of the connector 30 under the influence of external force. When the cover 20 is in the locked state, one of the areas of the abutting portion 35 may abut against the housing 10 (as shown in fig. 2). When the cover 20 is deflected, the abutting portion 35 may deflect relative to the housing 10, and the remaining area of the abutting portion 35 may abut against the housing 10 (as shown in fig. 4). The connector 30 and the housing 10 may be in a relatively stationary state when the external force is removed, and the cover 20 and the housing 10 may naturally be in a relatively stationary state. At this time, the cover 20 does not cover the opening 11, the opening 11 is in an exposed state, and the cover 20 is in an opened state.

When the cover plate 20 is switched from the open state (example shown in fig. 3) to the fastened state (example shown in fig. 1), the cover plate 20 can rotate counterclockwise relative to the housing 10 about the abutment 35 of the connector 30 under the influence of external force. When the cover 20 is in the open state, one of the areas of the abutment portion 35 may abut (as shown in fig. 4). When the cover 20 is deflected, the abutting portion 35 may deflect with respect to the housing 10, and the remaining area of the abutting portion 35 may first abut against the housing 10. Subsequently, the external force can be removed, and the cover plate 20 can continue to rotate counterclockwise under the action of self gravity. The housing 10 is sequentially abutted against different areas of the second end 37, the deflection speed of the cover plate 20 is gradually reduced, and when the cover plate 20 completely shields the opening 11, the cover plate 20 stops rotating, and the cover plate 20 is in a buckling state.

The above-described arrangement provides different regions in the abutment portion 35 of the connector 30. When the housing 10 abuts against one of the areas of the abutting portion 35, a certain angle is formed between the cover plate 20 and the mounting plane of the housing 10, and the opening 11 of the housing 10 is exposed. When the cover plate 20 deflects relative to the housing 10 to block the opening 11, the cover plate 20 can deflect relative to the housing 10 under the action of external force, and after the external force is removed, the cover plate 20 can continue to rotate under the action of gravity. The housing 10 can be sequentially abutted with the rest of the abutting portion 35, and the deflection speed of the cover plate 20 gradually slows down to finally stop rotating, at which time the cover plate 20 stops rotating and covers the opening 11.

When the cover 20 is engaged, if the deflection speed of the cover 20 is not limited, loud sounds may occur when the cover 20 is covered with the housing 10. In the process of deflecting the cover plate 20 to shield the opening 11, the deflection speed of the cover plate 20 is limited by the abutting of different areas of the abutting portion 35 and the housing 10, so that the deflection speed is gradually slowed down. Thus, when the cover 20 and the case 10 are finally covered, the sound generated when the cover 20 contacts the case 10 due to the combined action of the weight and the gravitational acceleration can be reduced.

In some embodiments, referring to fig. 8, the abutting portion 35 at least includes a first limiting portion 31, a second limiting portion 32 and a third limiting portion 33 sequentially arranged, and the first limiting portion 31, the second limiting portion 32 and the third limiting portion 33 are distributed in three different areas of the abutting portion 35 along a deflection direction of the cover 20 from the open state to the closed state.

When the cover 20 is in the open state, the first limiting portion 31 abuts against the housing 10. When the cover 20 is switched from the open state to the closed state, the second limiting portion 32 and the third limiting portion 33 are sequentially abutted against the housing 10.

Illustratively, as shown in fig. 8, the second end 37 is provided with a first limit stop 31, a second limit stop 32, and a third limit stop 33. The limiting portions can be abutted against the housing 10. When the cover plate 20 is in an open state, the first limiting part 31 is abutted with the matching part 12; when the cover 20 is switched from the open state to the closed state, the second limiting portion 32 and the third limiting portion 33 sequentially abut against the mating portion 12, and the deflection speed of the cover 20 gradually decreases. In this way, the structure of the abutment portion 35 is simplified on the basis of realizing the limiting function.

As shown in fig. 5, in some embodiments, the housing 10 may include a body 13 and a mount 14. The mounting member 14 is detachably connected to the body 13, for example, the mounting member 14 may be such that the body 13 may be connected together by fasteners such as bolts. Second, the body 13 may be provided with an opening 11, the mounting member 14 may be located beside the opening 11, and the mounting member 14 may be further provided with a fitting portion 12. Thus, after the attachment member 30 is installed, the second end 37 of the attachment member 30 is in fact coupled to the mounting member 14.

As shown in fig. 6, the housing 10 further includes a mating portion 12, and the mating portion 12 is a receiving groove formed in the mounting member 14. When the cover plate 20 deflects, the first limiting part 31, the second limiting part 32 or the third limiting part 33 is accommodated in the accommodating groove and is abutted against the accommodating groove.

The entire housing 10 is replaced when the mating portion 12 is damaged, as opposed to providing the mating portion 12 directly to the housing 10. The additional provision of the mounting member 14 and the provision of the mating portion 12 on the mounting member 14 not only facilitates the replacement of the mounting member 14 by a user when it is damaged, but also reduces the maintenance costs of the flip assembly 100.

In some examples, the groove wall of the receiving groove is provided with a protrusion 141. The second end 37 of the connector 30 is positionable in and rotatable within the receiving slot. When the second end 37 rotates in the accommodating groove at different angles, the first limiting portion 31, the second limiting portion 32 or the third limiting portion 33 of the second end 37 can respectively abut against the protruding portion 141, so that the cover plate 20 is driven to deflect by the connecting piece 30, and further, the switching of different states of the cover plate 20 is realized.

The above arrangement simplifies the structure of the mounting member 14, and facilitates the production and processing of the mounting member 14.

In some examples, the walls of the receiving groove may be provided with mounting holes into which the connection portion 34 may be inserted and clearance fit. Thus, the connection portion 34 can rotate relative to the mounting groove.

In other examples, the body 13 of the housing 10 may also be provided with a mounting hole, and the connection portion 34 is sequentially inserted into the body 13 and the mounting member 14 of the mounting member 14. Of course, when the housing 10 is directly provided with the mating portion 12, the housing 10 may be provided with a mounting hole, and the connection portion 34 may be directly movably connected with the housing 10.

The cover plate 20 can rotate to drive the connecting piece 30 to rotate, the abutting part 35 can rotate relative to the mounting groove under the drive of the connecting part 34, when the abutting part 35 rotates for different angles, the first limiting part 31, the second limiting part 32 and the third limiting part 33 respectively abut against the protruding part 141 in the mounting groove when the abutting part 35 rotates for different angles, so that the switching of different states of the cover plate 20 is realized.

As shown in fig. 8, in some examples, the surface of the abutment portion 35 forms a first limit portion 31, a second limit portion 32, and a third limit portion 33 having different recess depths. The first limiting portion 31, the second limiting portion 32, and the third limiting portion 33 are distributed in order along the deflection direction of the abutting portion 35. For example, when the abutment portion 35 is a cam, the first limiting portion 31, the second limiting portion 32, and the third limiting portion 33 may be sequentially distributed on the cam surface of the cam.

The first limiting portion 31, the second limiting portion 32 and the third limiting portion 33 are in interference contact with the mating portion 12, for example, the limiting portions may be in contact with the protruding portion 141 in the mounting groove. Thus, the connection mode between the limiting part and the matching part 12 is simplified, the bearing capacity of the connecting piece 30 is improved, and the service life of the connecting piece 30 is prolonged.

Wherein, the mating portion 12 and the mounting member 14 can be prepared from polyoxymethylene to improve the impact resistance of the mating portion and the mounting member.

In some examples, the recess depth of the first limiting portion 31 at the surface of the abutting portion 35 is greater than the recess depth of the second limiting portion 32 at the surface of the abutting portion 35, and when the first limiting portion 31 abuts against the mating portion 12, the interference when the first limiting portion 31 abuts against the mating portion 12 is greater than the interference when the second limiting portion 32 abuts against the mating portion 12.

For example, as shown in fig. 8, a first limit portion 31 and a second limit portion 32 having different recess depths may be formed on a cam surface of the cam, and the first limit portion 31 and the second limit portion 32 may be sequentially engaged. When the first limiting portion 31 abuts against the mating portion 12, the contact area between the cam surface of the cam and the mating portion 12 may be a; when the second limiting portion 32 abuts against the mating portion 12, the contact area between the cam surface of the cam and the mating portion 12 may be b, where a is greater than b. Thus, the cover plate 20 can deflect by applying external force to the cover plate 20, and the difficulty of deflection of the cover plate 20 is reduced.

In some examples, as shown in fig. 8, the second limiting portion 32 may be recessed to a greater depth than the first limiting portion 31 or the third limiting portion 33, respectively, on the cam surface of the cam. For example, the second limiting portion 32 may be a cambered surface concavely formed with respect to the first limiting portion 31 or the third limiting portion 33.

When the first limiting part 31 is switched to the second limiting part 32 to be abutted against the matching part 12, the contact area of the second limiting part 32 and the matching part 12 is smaller than that of the first limiting part 31 and the matching part 12 because the concave depth of the second limiting part 32 is larger than that of the first limiting part 31. It is understood that the resistance between the second limiting portion 32 and the engaging portion 12 is smaller than the resistance between the first limiting portion 31 and the engaging portion 12. The resistance formed between the second limiting portion 32 and the mating portion 12 may be smaller than the gravity of the cover 20, so that when the second limiting portion 32 abuts against the mating portion 12, the external force may be removed, and the cover 20 may continue to rotate under the action of the gravity.

Thus, when the cover plate 20 is in the open state, the user can automatically deflect the cover plate 20 only by applying an external force to the cover plate 20 in a short time, and the user does not need to apply an external force to the cover plate 20 all the time in the deflection process of the cover plate 20.

As the second end 37 of the connector 30 continues to deflect, the third limiting portion 33 may abut the mating portion 12. In some examples, the interference when the third limit portion 33 and the mating portion 12 abut is greater than the interference when the second limit portion 32 and the mating portion 12 abut.

With continued reference to fig. 8, the recess depth of the third limiting portion 33 at the surface of the abutting portion 35 is greater than the recess depth of the second limiting portion 32 at the surface of the abutting portion 35. It will be appreciated that the recess depth of the third limit portion 33 at the cam surface of the cam may be greater than the recess depth of the second limit portion 32 at the cam surface of the cam. As can be seen, the contact area between the third limit portion 33 and the mating portion 12 is larger than the contact area between the second limit portion 32 and the mating portion 12, and thus, the resistance formed between the third limit portion 33 and the mating portion 12 is larger than the resistance formed between the second limit portion 32 and the mating portion 12.

When the engaging portion 12 is switched from abutting against the second limiting portion 32 to abutting against the third limiting portion 33, the resistance formed before the connecting member 30 and the engaging portion 12 increases, so that the deflecting speed of the cover 20 can be gradually reduced, and when the cover 20 completely shields the opening 11 of the housing 10 and collides with the housing 10, the sound occurring between the cover 20 and the housing 10 can be reduced.

Referring to fig. 5, in some embodiments, the flip assembly 100 further includes a shield 40. The shield 40 is located on the side of the mounting member 14 remote from the body 13 and covers the mounting member 14. The cover 40 can be used as a decorative item to cover the mounting member 14 to enhance the appearance of the entire flip assembly 100.

Secondly, the application also provides a base station. The base station includes the flip assembly 100 described above. The sweeper has the functions and advantages of the flip cover assembly 100 provided by the above embodiments, and will not be described herein.

In addition, the application also provides a sweeper. The sweeper comprises the base station, so that the sweeper has the functions and the beneficial effects of the base station provided by the embodiment, and the details are not repeated here.

The technical features of the above-described embodiments may be arbitrarily combined, and all possible combinations of the technical features in the above-described embodiments are not described for brevity of description, however, as long as there is no contradiction between the combinations of the technical features, they should be considered as the scope of the description.

The above examples only represent a few embodiments of the present application, which are described in more detail and are not to be construed as limiting the scope of the claims. It should be noted that it would be apparent to those skilled in the art that various modifications and improvements could be made without departing from the spirit of the present application, which would be within the scope of the present application. Accordingly, the scope of protection of the present application is to be determined by the claims appended hereto.
