Detailed Implementation

[0031] The technical solutions of this application will be further described below with reference to specific embodiments, but this application is not limited to these embodiments.

[0032] like Figures 1 to 5 As shown, this embodiment proposes a sweeping adjustment mechanism, comprising a fixed base 11, a drive assembly 12, a rotating base 13, a reset component 14, a connecting assembly 15, and a sweeping assembly 16.

[0033] A drive assembly 12 is mounted on the fixed base 11. The drive assembly 12 has a rotatable drive shaft 121, which is used to drive the rotating base 13 to rotate.

[0034] A limiting structure is provided between the fixed base 11 and the drive shaft 121 to limit the rotation angle of the drive shaft 121;

[0035] One end of the reset member 14 is mounted on the fixed base 11, and the other end of the reset member 14 is mounted on the rotating base 13;

[0036] The sweeping assembly 16 is mounted on the rotating base 13 via the connecting assembly 15.

[0037] The technical advantage of this solution is that, while ensuring that the sweeping disc assembly 16 can unfold outward, it avoids the sweeping disc adjustment mechanism from being too large, making the overall structure more compact and reducing the need for installation space. It is particularly suitable for small road sweeping equipment, such as sidewalk sweepers.

[0038] In this solution, the fixed base 11 is used to install on the sweeper. This solution adopts a rotary drive to directly install the rotating base 13 on the fixed base 11 through the reset component 14. The sweeping disc assembly 16 is directly installed on the rotating base 13 through the connecting component 15. It has the advantages of simple structure and small size. In addition, the bottom of the fixed base 11 is provided with a limiting structure, which can effectively control the rotation angle of the drive shaft 121. Therefore, it can accurately control the outward position of the sweeping disc assembly 16.

[0039] The drive assembly 12 uses a rotary actuator, which can be a combination of a motor and a reducer, or a rotary cylinder.

[0040] Furthermore, the fixed base 11 has an upper support plate 111 and a lower support plate 112, and the housing of the drive assembly 12 is installed between the upper support plate 111 and the lower support plate 112.

[0041] The rotating base 13 has an upper mounting plate 131 and a lower mounting plate 132, which are rotatably mounted on the housing of the drive assembly 12.

[0042] The rotating base 13 uses the housing of the drive assembly 12 as its pivot, which effectively reduces the space occupied by the fixed base 11, the drive assembly 12 and the rotating base 13.

[0043] The lower support plate 112 and the lower mounting plate 132 are respectively provided with clearance holes for the drive shaft 121 to pass through.

[0044] Furthermore, the reset element 14 is a torsion spring, which is sleeved on the outer periphery of the drive assembly 12 housing. One end of the torsion spring is fixed on the fixed seat 11, and the other end of the torsion spring is fixed on the rotating seat 13.

[0045] As one embodiment of this example, the limiting structure includes a rotation limiting member 17, which is fixed to the lower end of the drive shaft 121, and has a first rotating arm 171.

[0046] The lower end face of the lower support plate 112 is provided with two first stop arms 172, and the first rotating arm 171 is located between the two first stop arms 172.

[0047] When the sweeping assembly 16 is retracted and in a non-working state, the first rotating arm 171 and the first first stop arm 172 abut together.

[0048] When the sweeping assembly 16 is extended and in working condition, the first rotating arm 171 and the second first stop arm 172 abut together.

[0049] Furthermore, the two first stop arms 172 are provided with gaskets on the side facing the first rotating arm 171.

[0050] As one embodiment of this invention, the rotating limiting member 17 also has a second rotating arm 173, and the lower end of the rotating seat 13 is provided with a second stop arm 174. Under the action of the torsion spring, the second rotating arm 173 and the second stop arm 174 are in pressure contact.

[0051] As the sweeping assembly 16 moves from the extended state to the retracted state, the second rotating arm 173 presses against the second stop arm 174, causing the rotating seat 13 to return to its initial position.

[0052] As one embodiment of this invention, a detection module 18 is provided on the lower support plate 112. The detection module 18 is used to detect the position of the first rotating arm 171.

[0053] The detection module 18 uses two proximity switches 181, which can be photoelectric switches.

[0054] A photoelectric switch is used to detect whether the first rotating arm 171 is in contact with the pad on the first first stop arm 172;

[0055] Another photoelectric switch is used to detect whether the first rotating arm 171 is in contact with the pad on the second first stop arm 172.

[0056] As one embodiment of this example, the connecting component 15 is a linkage mechanism. The linkage mechanism has a fixed part 151, a connecting part 152 and a floating part 153. One end of the connecting part 152 is hinged to the fixed part 151, and the other end of the connecting part 152 is hinged to the floating part 153.

[0057] The fixing part 151 is provided on the rotating base 13; wherein, the fixing part 151 can be welded to the rotating base 13, or the fixing part 151 can be integrally formed with the rotating base 13.

[0058] A sweeping assembly 16 is installed at the lower end of the floating part 153. The sweeping assembly 16 is prior art.

[0059] The sweeping assembly 16 includes a drive motor 161, a motor mount 162, and a sweeping part 163. The drive motor 161 is fixed on the floating part 153 via the motor mount 162, and the sweeping part 163 is mounted on the output shaft of the drive motor 161.

[0060] In one embodiment of this invention, the number of connecting rod portions 152 is two.

[0061] In one embodiment of this invention, a connecting member 19 is provided between the floating part 153 and the rotating seat 13. The connecting member 19 in this solution includes a spring, and may also include other telescopic structures in the prior art for controlling the vertical movement of the sweeping assembly 16. Since this solution mainly addresses the outward extension problem of the sweeping assembly 16, the lifting structure of the sweeping assembly 16 will not be described in detail, and this application does not involve improvements to the lifting structure of the sweeping assembly 16. Therefore, the lifting scheme of the sweeping assembly 16 will not be described in detail; this part can be referred to in the prior art.

[0062] The working principle of the outward and retraction of the sweeping component 16 in this solution is as follows:

[0063] In the initial state, the sweeping assembly 16 is in the retracted state, with the first rotating arm 171 and the first first stop arm 172 abutting against each other.

[0064] The process of the sweeping assembly 16 transitioning from the retracted state to the extended state is as follows: The drive shaft 121 of the drive assembly 12 rotates, and the first rotating arm 171 moves toward the second first stop arm 172. At this time, the second rotating arm 173 rotates synchronously, and the torsion spring releases its elastic potential energy. The rotating seat 13 rotates along with the second rotating arm 173 under the action of the torsion spring. When the first rotating arm 171 and the second first stop arm 172 come into contact, the proximity switch 181 sends the position information of the first rotating arm 171 to the control system. The control system then controls the drive assembly 12 to stop working, and the sweeping assembly 16 is now in the extended state.

[0065] The process of the sweeping assembly 16 moving from the extended state to the retracted state is as follows: the drive shaft 121 of the drive assembly 12 rotates in the opposite direction, the first rotating arm 171 moves in the opposite direction toward the first stop arm, and the second rotating arm 173 pushes against the second stop arm 174 in the opposite direction, causing the rotating seat 13 to rotate in the opposite direction. At this time, the torsion spring undergoes elastic torsion, accumulating elastic potential energy. When the first rotating arm 171 contacts the first stop arm, the proximity switch 181 sends the position information of the first rotating arm 171 to the control system, and the control system controls the drive assembly 12 to stop working. At this time, the sweeping assembly 16 is in the retracted state.

[0066] In addition, this application also proposes a sweeper that includes the above-mentioned sweeping disc adjustment mechanism.

[0067] For those skilled in the art, various modifications and improvements can be made without departing from the inventive concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
