[0030] Combine the following Figure 1 and Figure 2 The technical solution provided by the utility model is described in more detail.

[0031] Embodiment 1:

[0032] The top brush lifting drive mechanism provided by the utility model comprises a stand 6, a driving device 1, a driving wheel assembly, a traction part 4 and a counterweight assembly, wherein: the driving device 1 is fixed on the stand 6 and is drivingly connected to the driving wheel assembly, and is used to drive the driving wheel assembly to rotate forward or reversely; a part of the traction part 4 is wound around the driving wheel assembly, and the other end of the traction part 4 is fixedly connected to the top brush assembly, and when the driving wheel assembly rotates forward or reversely, it can wind up or release the traction part 4 to lift the top brush assembly; the counterweight assembly is connected to the driving wheel assembly, and the counterweight assembly and the top brush assembly are respectively located on opposite sides of the driving wheel assembly, and the movement directions of the counterweight assembly and the top brush assembly are opposite; when the top brush assembly is stationary, the counterweight assembly and the top brush assembly are in a balanced state.

[0033] See also Figure 1 and Figure 2As shown, the driving device 1 includes a motor and a reducer, and the output shaft 11 of the reducer is lengthened and drivingly connected to the driving wheel assembly. The traction part 4 can be a traction belt, a steel wire rope, etc.

[0034] In the top brush lifting drive mechanism of this embodiment, the counterweight assembly and the top brush assembly are respectively located on opposite sides of the driving wheel assembly, and the movement direction of the counterweight assembly is opposite to that of the top brush assembly. When the top brush assembly rises, the counterweight assembly descends, and the gravity of the counterweight assembly can play a role in pulling the top brush assembly to a certain extent. The driving device 1 is only responsible for outputting forward or reverse power, which can appropriately reduce the power of the driving device 1 to a certain extent; it can make the top brush assembly run more smoothly, extend its service life, and reduce costs; and when the top brush assembly is stationary, the counterweight assembly and the top brush assembly are in a balanced state to ensure the stability of the structure.

[0035] As an optional embodiment, a portion of the counterweight assembly is wound around the driving wheel assembly. When the driving device 1 rotates forward, the driving wheel assembly can release the counterweight assembly and wind up the traction portion 4, so that the movement direction of the counterweight assembly is opposite to that of the top brush assembly.

[0036] With such arrangement, when the top brush assembly rises, the driving wheel assembly releases the counterweight assembly, causing the counterweight assembly to descend. The gravity of the counterweight assembly can play a role in pulling the top brush assembly to a certain extent, and the driving device 1 is only responsible for outputting forward or reverse power, which can appropriately reduce the power of the driving device 1 to a certain extent.

[0037] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the driving wheel assembly includes a counterweight wheel 21 and a transmission wheel 22, wherein: the driving device 1 is drivingly connected to the counterweight wheel 21, and is used to drive the counterweight wheel 21 to rotate forward or reversely; the counterweight wheel 21 is drivingly connected to the transmission wheel 22, and is used to drive the transmission wheel 22 to rotate reversely or forwardly; a part of the traction part 4 is wound around the transmission wheel 22, and a part of the counterweight assembly is wound around the counterweight wheel 21.

[0038] The function of the counterweight wheel 21 is to wind up a part of the counterweight assembly, and the transmission wheel 22 winds up the traction part 4. When the top brush assembly needs to rise, the driving device 1 rotates to make the transmission wheel 22 wind up the traction part 4, and at the same time, the counterweight wheel 21 releases the counterweight assembly, and the counterweight assembly descends. The gravity of the counterweight assembly can play a role in pulling the top brush assembly to a certain extent, so the power of the driving device 1 is appropriately reduced. Conversely, when the top brush assembly descends, the driving device 1 rotates in the other direction, so that the transmission wheel 22 releases the traction part 4, and at the same time, the counterweight wheel 21 winds up the counterweight assembly, and the counterweight assembly rises, which can balance the gravity of the top brush assembly and prevent the top brush assembly from descending too quickly and becoming unstable.

[0039] As an optional embodiment, the weight wheel 21 and the transmission wheel 22 are connected by a chain (such as Figure 1 and Figure 2 As shown) or belt drive connection, such an arrangement allows a drive device 1 to simultaneously drive the rotation of the counterweight wheel 21 and the transmission wheel 22, with a simple and compact structure.

[0040] As an alternative embodiment, see Figure 1 and Figure 2 As shown, the counterweight assembly includes a connecting belt 31 and a counterweight block 32 , wherein: one end of the connecting belt 31 is wound around the driving wheel assembly, and the other end of the connecting belt 31 is fixedly connected to the counterweight block 32 .

[0041] When the top brush assembly rises, the driving device 1 rotates to make the transmission wheel 22 wind up the traction part 4, and at the same time, the counterweight wheel 21 releases the connection belt 31, and the counterweight block 32 descends. The gravity of the counterweight block 32 can play a role in pulling the top brush assembly to a certain extent, so the power of the driving device 1 is appropriately reduced. Conversely, when the top brush assembly descends, the driving device 1 rotates in the other direction, so that the transmission wheel 22 releases the traction part 4, and at the same time, the counterweight wheel 21 winds up the connection belt 31, and the counterweight block 32 rises, which can balance the gravity of the top brush assembly and prevent the top brush assembly from descending too quickly and becoming unstable.

[0042] As an alternative embodiment, see Figure 1 As shown, the top brush lifting drive mechanism also includes a fixed pulley assembly, which is rotatably connected to the top of the stand 6, and the traction part 4 passes around the fixed pulley assembly and is fixedly connected to the top brush assembly. The fixed pulley assembly plays a role in reversing the traction part 4.

[0043] For details, see Figure 1 As shown, the fixed pulley assembly includes a first fixed pulley 51 and a second fixed pulley 52, which are rotatably connected to the opposite sides of the top of the stand 6 respectively; the traction part 4 includes a first traction part 41 and a second traction part 42, which are jointly wound around the driving wheel assembly, and the first traction part 41 bypasses the first fixed pulley 51 and is fixedly connected to one end of the top brush assembly, and the second traction part 42 bypasses the second fixed pulley 52 and is fixedly connected to the other end of the top brush assembly.

[0044] The first traction part 41 and the second traction part 42 are fixedly connected to the opposite ends of the top brush assembly respectively. When the driving device 1 is running, the first traction part 41 and the second traction part 42 can be wound or released at the same time, and the opposite ends of the top brush assembly can be lifted or released at the same time, so that the top brush assembly remains in a horizontal state, thereby ensuring the stability of the top brush assembly during operation.

[0045] Embodiment 2:

[0046] This embodiment provides a car washing device, see Figure 1 As shown, it includes a top brush assembly and the above-mentioned top brush lifting drive mechanism.

[0047] As an optional embodiment, the top brush assembly includes a bracket 72, a rotation drive device 73 and a top brush body 71, wherein: the traction portion 4 is fixedly connected to the bracket 72, the top brush body 71 is rotationally connected to the bracket 72, the rotation drive device 73 is fixed to the bracket 72, and is drivingly connected to the top brush body 71, and is used to drive the top brush body 71 to rotate around its own axis.

[0048] The first traction part 41 and the second traction part 42 are respectively fixedly connected to the opposite ends of the bracket 72. When the rotation driving device 73 rotates, the first traction part 41 and the second traction part 42 simultaneously lift or release the opposite ends of the bracket 72, thereby realizing the lifting and lowering of the top brush body 71. The rotation driving device 1 can be a motor, which is used to drive the top brush body 71 to rotate, thereby improving the cleaning effect.

[0049] Since the car washing device has the above-mentioned top brush lifting drive mechanism, the power of the drive device 1 can be appropriately reduced to a certain extent; the top brush assembly can be made to run more smoothly, the service life can be extended, and the cost can be reduced; and when the top brush assembly is stationary, the counterweight assembly and the top brush assembly are in a balanced state, ensuring the stability of the structure.

[0050] In the description of this specification, specific features, structures or characteristics may be combined in an appropriate manner in any one or more embodiments or examples.
