[0032] Next, the embodiments of this specification are described in detail.

[0033] Currently, some sweepers have a swing assembly that drives the cleaning assembly to swing outward, allowing the cleaning assembly to extend outside the sweeper. When the cleaning assembly is in the outward swing position and is struck, there is a significant risk of damage. The present disclosure provides a swing assembly and a sweeper to address this issue.

[0034] like Figures 1 to 3 As shown, the present disclosure provides a swing assembly, including a base 10, a drive assembly 20, a swing assembly 30, and a cleaning assembly 40. The drive assembly 20 is fixed to the base 10, and the cleaning assembly 40 is slidably mounted on the base 10. A slide groove 11 is provided on the base 10, and the slide groove 11 is slidably engaged with the cleaning assembly 40.

[0035] The swing assembly 30 includes an input portion 31, an output portion 32, and an elastic member 33. The elastic member 33 connects the input portion 31 and the output portion 32. The drive assembly 20 is connected to the input portion 31 to drive the output portion 32 to move, thereby causing the cleaning assembly 40 to move along a predetermined trajectory between a retracted position, at least partially within the base 10, and an outward swing position, at least partially outside the base 10. The drive assembly 20 of the present disclosure can be a motor.

[0036] like Figure 1 As shown, when in the retracted position, at least a portion of the cleaning assembly 40 is located within the base 10. Figure 2 and Figure 3 As shown, when in the outward swing position, at least a portion of the cleaning component 40 is located outside the base 10. The specific form of the preset trajectory is not limited. In one embodiment, the preset trajectory can be an arc, and the movement process of the cleaning component 40 is relatively smooth, which can reduce the impact force when the cleaning component 40 is hit.

[0037] When the cleaning assembly 40 is squeezed in the outward swing position, the elastic member 33 compresses, allowing the cleaning assembly 40 to retract from the outward swing position to any position within the preset trajectory. The elastic member 33 allows for flexible retraction of the cleaning assembly 40. When squeezed, the elastic member 33 absorbs the squeezing force and compresses, preventing the cleaning assembly 40 from forcibly colliding with obstacles and reducing the risk of damage to the swing mechanism. Furthermore, after the collision, the elastic force generated by the elastic member 33 can also pull the cleaning assembly 40 back to the outward swing position, improving the user experience.

[0038] The present disclosure also provides a sweeper including the aforementioned swing mechanism. The sweeper of the present disclosure exhibits high stability and a superior user experience. The cleaning assembly 40 can flexibly retract, and the elastic member 33 can absorb the squeezing force, thereby preventing the cleaning assembly 40 from forcibly colliding with obstacles and reducing the risk of damage to the sweeper. After the collision, the elastic member 33 can also drive the cleaning assembly 40 back to its outward swing position.

[0039] like Figure 4 As shown, in one embodiment, a sway assembly 30 is provided with a receiving space 300. A mounting shaft 301 is disposed within the receiving space 300, and an elastic member 33 is a torsion spring sleeved around the mounting shaft 301. By configuring the elastic member 33 as a torsion spring and installing the torsion spring within the receiving space 300, the sway mechanism becomes more compact, thereby improving its stability and further reducing the risk of damage. In other embodiments, the elastic member 33 can be of any type and can be a tension spring, a compression spring, or other similar material. Alternatively, the elastic member 33 can be a component made of an elastic material, such as a rubber strip.

[0040] like Figure 4As shown, the input portion 31 may include a cover 311 and a stopper 312. The output portion 32 may include a first output member 321 and a second output member 322, which are rotatably mounted. The first output member 321 is connected to the elastic member 33, and the second output member 322 is connected to the cleaning assembly 40. The first output member 321 and the second output member 322 form a connecting rod mechanism, which has a simple structure, is easy to manufacture, and can achieve high manufacturing precision. The second output member 322 may be provided with a boss 3223 to enhance the connection strength.

[0041] In one embodiment, the first output member 321 may be box-shaped, and the accommodation space 300 is formed by the first output member 321 and the cover 311. The accommodation space 300 comprises the power-transmitting portion of the swing assembly 30. The input portion 31 and the output portion 32 function both to transmit power and to form the accommodation space 300. This arrangement further enhances the structural compactness of the swing mechanism, thereby strengthening its stability and reducing the risk of damage. In other embodiments, the arrangement of the accommodation space 300 is not limited.

[0042] In one embodiment, if Figure 4 As shown, the first output member 321 may be provided with a plate 3214, and the plate 3214 may be provided with a slot 3215. The stopper 312 extends from the cover 311 into the accommodation space 300. One end of the elastic member 33 is assembled into the slot 3215, and the other end of the elastic member 33 abuts the stopper 312. One end of the elastic member 33 is assembled into the slot 3215, which facilitates assembly and can limit the elastic member 33, thereby improving the stability of the elastic member 33. Since the other end of the elastic member 33 is in abutment with the stopper 312, the cover 311 does not need to be positioned more precisely during installation. After the cover 311 and the first output member 321 are installed in conjunction, the cover 311 can be rotated to achieve abutment with the elastic member 33, thereby improving installation efficiency.

[0043] like Figure 5 and Figure 6 As shown, in one embodiment, the first output member 321 may include a connecting portion 3211 and a pushing portion 3212. The connecting portion 3211 is disc-shaped, and the pushing portion 3212 is semicircular. The second output member 322 is rod-shaped. The second output member 322 and the pushing portion 3212 are disposed on the same end surface of the connecting portion 3211. This reduces the volume occupied by the output portion 32, thereby making the swing mechanism more compact and further improving its stability.

[0044] In one embodiment, the second output member 322 may include a pair of contact surfaces 3221 disposed opposite each other. When the cleaning assembly 40 is in the outward swing position, the push portion 3212 abuts against one of the pair of contact surfaces 3221. When the cleaning assembly 40 is in the retracted position, the push portion 3212 abuts against the other of the pair of contact surfaces 3221. The first output member 321 and the second output member 322 form a disc-link mechanism, which transmits force between the first output member 321 and the second output member 322 through surface contact, thereby improving the smoothness and stability of the swing assembly 30 during movement and further reducing the risk of damage to the swing mechanism.

[0045] Specifically, Figure 5 and Figure 6 This is a structural diagram of the swing assembly 30 when the cleaning assembly 40 is in the outward swing position. During the outward swing process, the power of the driving assembly 20 is transmitted to the input part 31. Figure 6 From a perspective of , the input portion 31 rotates clockwise. The stopper 312 squeezes the elastic member 33, which transmits its deformation to the first output member 321 through the slot 3215 on the plate 3214. The first output member 321 also rotates clockwise, pushing the second output member 322 inward and causing the cleaning assembly 40 to swing outward. To reduce friction during the outward swing, a lifting structure can be provided on the cleaning assembly 40.

[0046] When the cleaning assembly 40 is impacted in the outward swing position, it retracts slightly. The second output member 322 drives the first output member 321 to rotate counterclockwise. Since the drive assembly 20 has stopped rotating, the input portion 31 is also stationary, causing the elastic member 33 to be squeezed and deformed. After the impact, the cleaning assembly 40, under the action of the elastic member 33, returns to the outward swing position.

[0047] Figure 7 and Figure 8 The structure diagram of the swing assembly 30 when the cleaning assembly 40 is in the retracted position. Figure 8 From a perspective of , the drive assembly 20 drives the input portion 31 to rotate counterclockwise. The stopper 312 stretches the elastic member 33, driving the first output member 321 to rotate counterclockwise. The stopper 312 can also directly abut the first output member 321, pushing it to rotate counterclockwise. The first output member 321 drives the second output member 322 to extend, causing the cleaning assembly 40 to retract.

[0048] like Figure 7As shown, one of the pushing portion 3212 and the contact surface 3221 is provided with a protrusion 3213, and the other is provided with a groove 3222 that cooperates and abuts with the protrusion 3213. The cooperation and fixation of the protrusion 3213 and the groove 3222 facilitates the fit between the contact surface 3221 and the pushing portion 3212, improves the transmission of the acting force, and further enhances the stability of the swing mechanism.

[0049] like Figure 2 As shown, in one embodiment, the base 10 may be provided with a first light-interruption sensor 50 and a second light-interruption sensor 60 electrically connected to the drive assembly 20. When the cleaning assembly 40 is in the extended position, the first light-interruption sensor 50 is blocked. When the cleaning assembly 40 is in the retracted position, the second light-interruption sensor 60 is blocked.

[0050] When the cleaning component 40 moves, the first light-interrupting sensor 50 can sense that the cleaning component 40 has reached the outward swing position, and the second light-interrupting sensor 60 can sense that the cleaning component 40 has reached the retracted position. When the light-interrupting sensor detects that the cleaning component 40 has reached the corresponding position, the driving component 20 stops working. Using the light-interrupting sensor to monitor the outward swing position and the retracted position of the cleaning component 40 can ensure that the cleaning component 40 stops accurately at the outward swing position or the retracted position, further improving the user experience. In other embodiments, an angle sensor can be provided, and when the cleaning component 40 rotates to a certain angle, the driving component 20 stops moving.

[0051] The above is only a preferred embodiment of the present disclosure and does not limit the present disclosure in any form. Moreover, the above embodiments can complement each other in the absence of conflict. Although the present disclosure has been disclosed as a preferred embodiment as above, it is not intended to limit the present disclosure. Any technician familiar with this profession can make some changes or modifications to equivalent embodiments of the above-disclosed technical content without departing from the scope of the technical solution of the present disclosure. However, any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present disclosure without departing from the content of the technical solution of the present disclosure are still within the scope of the technical solution of the present disclosure.
