[0102] In one specific embodiment, the hinge portion 23 of the hinge member can be hinged to the motor fixing portion 2011 provided at one end of the cleaning head housing 201. The electrical connection plug 22 is engaged with the electrical connection mating member 15, so that one end of the hinge conductive member 2 is detachably electrically connected to the power receiving end 1a of the cylindrical electric drive assembly 1, and the other end is used to hinge to the cleaning head housing. The rotation output end 1b is used to receive the torque of the drive motor 12 and output the torque through the output shaft 14 to drive the roller assembly 202 of the cleaning machine 200 to rotate. The rotation mounting end is rotatably connected to the other end of the cleaning head housing 201 and has a travel along the axial direction of the cylindrical electric drive assembly 1.

[0103] In one specific embodiment, the cylindrical electric drive assembly further includes a hinge end sealing plug 11 disposed at the power receiving end 1a, and the hinge end sealing plug 11 is sleeved with the hinge sleeve portion 21. The cylindrical electric drive assembly 1 includes a motor thermal protection cylinder 10 and a drive motor 12 disposed within the motor thermal protection cylinder 10. The electrical connection mating member 15 is partially accommodated in the motor thermal protection cylinder 10 and connected to the drive motor 12.

[0105] The beneficial effects of this utility model are as follows: The electric drive device 100 provided by this utility model is built into the cleaning roller assembly. By setting a hinged conductive member 2 that connects the power receiving end 1a and the motor fixing part 2011 respectively, and detachably sleeved the hinged part 21 of the hinged conductive member 2 to the power receiving end, and hinged the hinged part 23 of the hinged conductive member 2 to the motor fixing part 2011 of the cleaning head housing, the electric drive device 100 can be easily disassembled from the cleaning head housing 201. By setting an electrical connection fitting 15 at the power receiving end 1a of the cylindrical electric drive assembly 1, and fitting the electrical connection fitting 15 to the electrical connection plug 22 of the hinged conductive member 2, when the drive motor 12 needs to be repaired and disassembled, it is only necessary to pull out the cylindrical electric drive assembly 1 and remove and install the drive motor 12 by inserting and pulling the hinged conductive member 2. It is not necessary to cut the motor lead wire or weld the motor lead wire, which improves the convenience of repair, disassembly and installation, thereby improving the work efficiency of repair and disassembly and installation and reducing the consumption of repair materials.

[0106] In the embodiments of this utility model, such as Figure 2 and Figures 14 to 16 As shown, the hinged conductive component 2 includes: a hinged sleeve portion 21, an electrical connection plug 22, and a hinged hinge portion 23; the hinged sleeve portion 21 is sleeved with the power receiving end 1a of the cylindrical electric drive assembly 1; the electrical connection plug 22 is disposed in the middle of the hinged sleeve portion 21 and is matched with the electrical connection mating part 15 disposed on the power receiving end 1a of the cylindrical electric drive assembly 1; the hinged hinge portion 23 is disposed on the back of the hinged sleeve portion 21 and is used to hinge with the motor fixing part 2011.

In this embodiment, for ease of installation, the outer diameter of the hinge portion 23 is smaller than that of the hinge sleeve portion 21. The hinge conductive component 2 is divided into the hinge sleeve portion 21 and the hinge portion 23, which can effectively separate the electrical connection plug 22 disposed in the hinge sleeve portion 21 from the hinge area, ensuring that the contact area of ​​the electrical connection plug 22 is not contaminated by the hinge area in contact with the external contact, and thus ensuring the cleanliness of the contact area of ​​the electrical connection plug 22 to a certain extent.

[0108] To ensure good dust protection inside the cylindrical electric drive assembly 1, in this embodiment of the invention, such as... Figure 3 , Figure 4 and Figure 11 As shown, the electric drive device 100 further includes: a hinge end sealing plug 11, which is installed on the power receiving end 1a of the cylindrical electric drive assembly 1; and an electrical connection fitting 15 disposed in the middle of the hinge end sealing plug 11.

The material for the hinge end seal must be an insulating material, such as insulating rubber.

[0109] Specifically, please refer to the embodiments of this utility model for further details. Figure 4 and Figure 11 The hinge end sealing plug 11 includes a sealing plug sealing part 111 and a sealing plug sleeve part 112. The sealing plug sealing part 111 is sealed to the inner wall of the housing of the cylindrical electric drive assembly 1, and the sealing plug sleeve part 112 is sleeved to the hinge member sleeve part 21. The sealing connection can be a threaded connection or an adhesive connection; in this embodiment of the present invention, a threaded connection is used. The above-described arrangement of the hinge end sealing plug 11 facilitates the connection of the hinge conductive member 2 to the main body of the cylindrical electric drive assembly 1 and ensures good coaxiality between the hinge conductive member 2 and the cylindrical electric drive assembly 1.

[0110] Specifically, in the embodiments of this utility model, such as Figure 8 , Figure 10, Figure 11 , Figure 14 , Figure 15 As shown, the drive rotation end button assembly 3 includes: an end button mounting base 31, an inner cylinder coupling 32, an end cap 33, and an end cap spring 34; the end button mounting base 31 is rotatably mounted on the inner cylinder of the roller assembly 202, with a through-center; one end of the inner cylinder coupling 32 is rotatably mounted on the middle of the end button mounting base 31 and is connected to the output shaft 14 of the cylindrical electric drive assembly 1, and the other end has a mounting groove (not shown in the figure), and the outer periphery of the mounting groove has a snap-fit ​​part 321, which is used to drive the roller assembly 202 of the cleaning machine 200 to rotate; one end of the end cap 33 is sleeved on the mounting groove 321 and limited by the limiting structure between the mounting groove 321 and the end cap 33, and the other end is rotatably connected to the cleaning head housing 201; the end cap spring 34 is clamped between the end cap 33 and the mounting groove so that the end cap 33 extends out of the mounting groove. In use, the end button mounting base 31 is driven to rotate by the output shaft 14 of the cylindrical electric drive assembly 1. The end button mounting base 31 drives the inner cylinder coupling 32 to rotate. The snap-fit ​​part 3211 of the inner cylinder coupling 32 snaps into the drive coupling end 202A of one end of the roller assembly 202 of the cleaning machine 200, driving the roller assembly 202 to rotate. The driven friction end 202B of the inner cylinder of the roller assembly 202 can be rotatably mounted on the mounting structure provided on the cleaning head housing 201, for example, it can be rotatably mounted on the outer periphery of the motor fixing part 2011. The snap-fit ​​part 321 can be provided with a fin-shaped structure that matches the corresponding slot provided on the inner cylinder of the roller assembly 202. When it is necessary to disassemble the built-in electric drive device 100 of this cleaning roller assembly, simply press the end cap 33, and the end cap 33 will retract and can be removed from the snap-fit ​​position of the cleaning head housing 201, which is quite convenient.

[0111] Specifically, in the embodiments of this utility model, such as Figure 8 , Figure 10 , Figure 14 and Figure 15 As shown, the limiting structure includes a limiting oblong hole 35 and a limiting pin 36. The limiting oblong hole 35 is formed on the side wall of the end cap 33 along the telescopic direction of the end cap 33. The limiting pin 36 passes through the side wall of the mounting groove to limit the limiting oblong hole 35. The cooperation between the limiting pin 36 and the limiting oblong hole 35 makes it difficult for the end cap 33 to pop off from the cleaning head housing 201, thus enhancing the reliability of the end cap 33 during use.

[0112] In this embodiment of the utility model, please refer to Figure 8 , Figure 10 and Figure 11As shown, the inner peripheral wall of the end button mounting base 31 is rotatably mounted on the inner cylinder of the roller assembly 202 of the cleaning machine 200 and is provided with a mounting base friction part 311. The outer peripheral wall of the inner cylinder coupling 32, which rotatably cooperates with the inner peripheral wall of the end button mounting base 31, is provided with a coupling friction part 3211. The mounting base friction part 311 and the coupling friction part 3211 can be metal rings. The setting of the mounting base friction part and the coupling friction part increases the service life of the end button mounting base 31.

The arrangement of each unit of the cylindrical electric drive assembly 1 within the motor thermal protection cylinder 10 effectively ensures that each unit of the cylindrical electric drive assembly 1 is not easily contaminated by dust or moisture, thus improving the reliability of each unit in use.

[0115] In the embodiments of this utility model, such as Figure 11 , Figure 14 , Figure 15 As shown, an output end sealing plug 141 is provided on the inner wall of the motor heat-conducting protection cylinder 10 at a corresponding position on the outer periphery of the output shaft 14. The setting of the output end sealing plug 141 further ensures the dustproof characteristics of the cylindrical electric drive assembly 1.

[0116] Secondly, this utility model embodiment also provides a cleaning machine 200, which includes a cleaning head housing 201, a roller assembly 202, and an electric drive device 100 as described in the first aspect. The cleaning head housing 201 has a motor fixing part 2011, which is hinged to the first end of the hinged conductive member 2. The second end of the hinged conductive member 2 is detachably electrically connected to the power receiving end 1a of the cylindrical electric drive assembly 1. The roller assembly 202 is driven to rotate by the rotation output end 1b of the drive rotation knob assembly 3. Since this cleaning machine 200 adopts all the technical solutions of the electric drive device 100 described above, it also has corresponding technical effects, which will not be elaborated further here.

[0117] Specifically, in the embodiments of this utility model, such as Figures 6 to 9 As shown, the motor fixing part 2011 includes a fixing part body 20111, and a hinge joint receiving cavity 20112 and a wire harness receiving cavity 20113 opened on the fixing part body 20111. The side wall of the hinge joint receiving cavity 20112 is provided with a pin hole 20114 for cooperating with the hinge pin 20115 and for hinged with the corresponding hinge conductive member 2. The wire harness receiving cavity 20113 is used for the wire harness led out from the hinge conductive member 2 to pass through.

[0118] Specifically, please refer to the embodiments of this utility model for further details. Figures 6 to 9 The fixing body 20111 has an annular clearance step 20116 at the corresponding position of the pin hole 20114. The setting of the annular clearance step 20116 provides a large range of motion between the fixing body 20111 and the hinge conductive component 2 at the hinge position, which avoids the inconvenience of rotating the fixing body 20111 and the hinge conductive component 2 when disassembling the built-in electric drive device 100 of the cleaning roller assembly, and improves the ease of disassembly.

[0119] Specifically, in the embodiments of this utility model, such as Figure 6 , Figure 8 and Figure 12 As shown, the inner cylinder of the roller assembly 202 is rotatably connected to the outer periphery of the motor fixing part 2011 at one end of the hinged conductive part 2. This rotatable connection between the inner cylinder of the roller assembly 202 and the outer periphery of the motor fixing part 2011, along with the hinge button, provides rotational support for the inner cylinder of the roller assembly 202 at a relatively large distance, minimizing radial runout during rotation and ensuring low noise during equipment operation.

[0120] Specifically, in the embodiments of this utility model, such as Figure 5 , Figure 6 and Figure 8 and Figure 9As shown, a roller rotation mounting friction part 20117 is provided at the rotatable connection between the outer periphery of the motor fixing part 2011 and the roller assembly 202. The roller rotation mounting friction part 20117 reduces the wear of the roller assembly 202 on the main body of the motor fixing part 2011, and ensures the reliability of the hinged installation of the built-in electric drive device 100 of the cleaning roller assembly.

[0121] Specifically, in the embodiments of this utility model, such as Figure 5 and Figure 6 As shown, the mounting insertion side of the roller rotating mounting friction part 20117 is provided with a sleeve clearance chamfer 20118. The sleeve clearance chamfer 20118 facilitates the installation of the roller assembly 202.

[0122] In this embodiment of the utility model, please refer to Figure 4 and Figure 5 As shown, the cleaning head housing 201 has a locking interface 2012 at the corresponding position of the rotating mounting end of the drive rotary knob assembly 3, and a wear-resistant ring 20121 is provided on the inner side of the locking interface 2012. The wear-resistant ring 20121 reduces the wear of the locking interface 2012 on the rotating mounting end of the drive rotary knob assembly 3.
