[0002] The car washing device in the prior art includes side brushes and a cross beam. The cross beam is horizontally arranged on the top of the car washing device, and two side brushes are respectively located at both ends of the cross beam. When washing the car, the two side brushes move toward each other along the cross beam until they contact the side of the car body, thereby cleaning the left side and the right side of the car body respectively.

[0003] In the above structure in the prior art, the side brush needs to be driven by a reducer to move along the cross beam. When washing a car, it is necessary to detect the current change of the reducer. When the current exceeds the rated value, the reducer is turned on.

Therefore, in addition to the reducer that drives the side brush to move along the cross beam, the travel mechanism of the side brush in the prior art also needs to be equipped with a current switch and a photoelectric switch. The photoelectric switch determines whether it is in contact with the car body by detecting the position and posture of the side brush. When the brush encounters resistance, the above switch transmits a signal to the controller, and the controller controls the brush to stop moving, thereby cleaning the car body.

[0004] The applicant has found that the prior art has at least the following technical problems: the walking mechanism of the side brush in the prior art has a complex structure and needs to be equipped with a current switch and a photoelectric switch to control the start and stop of the side brush, which is costly and has poor stability in equipment operation.

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments.

In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0033] The car washing device in the prior art includes a side brush and a crossbeam. The crossbeam is horizontally arranged at the top of the car washing device. Two side brushes are respectively located at the two ends of the crossbeam. When washing the car, the two side brushes move toward each other along the crossbeam until they contact the side of the car body, thereby cleaning the left and right sides of the car body respectively. In the above structure in the prior art, the side brush needs to be driven by a reducer to move along the crossbeam. When washing the car, it is necessary to detect the current change of the reducer. When the current exceeds the rated value, the reducer is turned on. When the current is less than the rated value, the reducer is turned off. Therefore, in addition to the reducer that drives the side brush to move along the crossbeam, the travel mechanism of the side brush in the prior art also needs to be provided with a current switch and a photoelectric switch. The photoelectric switch determines whether it is in contact with the car body by detecting the position and posture of the side brush. When the brush encounters resistance, the above switch transmits a signal to the controller, and the controller controls the brush to stop moving, thereby cleaning the car body. The travel mechanism of the side brush in the prior art has a complex structure and needs to be provided with a current switch and a photoelectric switch to control the start and stop of the side brush, etc., which is costly and has poor stability in equipment operation.

[0034] In view of the above problems, the embodiments of the utility model provide a brush body traveling mechanism and a car washing device. When the traveling wheel frame drives the brush body to contact the equipment to be cleaned, no reducer or other drive is required, the structure is simple, and the cost is reduced.

[0035] Combine the following Figure 1-Figure 3 The technical solution provided by the utility model is described in more detail.

[0036] Embodiment 1:

[0037] See also Figure 1-Figure 3 As shown, the brush body walking mechanism provided by the utility model includes a crossbeam 1 and a walking wheel frame 2 drivingly connected to the brush body 100, wherein: the crossbeam 1 includes at least two walking tracks 11, the two walking tracks 11 are inclined relative to the horizontal plane, and the lower ends of the two walking tracks 11 are connected; the walking wheel frame 2 is rollingly connected to the corresponding walking track 11, and the walking wheel frame 2 can roll toward the lower end of the walking track 11 under the action of gravity.

[0038] Combination Figure 1 and Figure 2 , Figure 3 As shown, the crossbeam 1 is located at the top of the car washing device. The crossbeam 1 of this embodiment includes two sections of connected walking tracks 11, and the walking tracks 11 are inclined. Figure 2 and Figure 3 As shown, the running track 11 has a high end A and a low end B, and the running track 11 gradually inclines downward from the high end A to the low end B.

[0039] In this way, when the travel wheel frame 2 drives the brush body 100 to contact the equipment to be cleaned (such as a car), the travel wheel frame 2 can roll toward the lower end B of the travel track 11 under the action of gravity without the need for the drive device to drive. The equipment to be cleaned, such as a car, is located between the two brush bodies 100 (see Figure 1 ), when the traveling wheel frame 2 drives the brush body 100 to move to contact with the vehicle body, the brush body encounters resistance and naturally stops moving. At this time, the brush body cleans the equipment to be cleaned, such as a car.

[0040] See also Figure 3 As shown, the brush body walking mechanism also includes a driving device, which is connected to the corresponding walking wheel frame 2 in a transmission manner, and the driving device is used to pull the walking wheel frame 2 back to the high end of the walking track 11.

[0041] The traveling wheel frame 2 is pulled back to the high end A of the traveling track 11 by a driving device after cleaning is completed.

[0042] Specifically, the running wheel frame 2 includes a brush body driving mechanism 23, which is connected to the brush body driving and is used to drive the brush body 100 to rotate around its own axis, thereby cleaning the vehicle body. The brush body driving mechanism 23 can be a reducer.

[0043] The brush body walking mechanism of this embodiment, since the walking tracks 11 are inclined relative to the horizontal plane, and the lower ends of the two walking tracks 11 are connected, the walking wheel frame 2 can descend along the walking tracks 11 under the action of gravity until it contacts the equipment to be cleaned, without the need to drive the walking wheel frame 2 to contact the equipment to be cleaned through a drive device such as a reducer. Since the brush body is driven and connected to the walking wheel frame 2, the brush body can clean the equipment after contacting it. After cleaning, the drive device pulls the walking wheel frame 2 back to the high end of the walking track 11 to wait for the next cleaning work. In the brush body walking mechanism, the walking wheel frame 2 does not need a reducer or other drive when driving the brush body to contact the equipment to be cleaned, and the structure is simple, which reduces the cost.

[0044] As an alternative embodiment, see Figure 2 and Figure 3 As shown, the two running tracks 11 are symmetrically arranged about the connection part between the two, so that the crossbeam 1 is in a V-shaped structure. The running wheel frames 2 include two running wheel frames 2, which are located in the corresponding running tracks 11. The two running wheel frames 2 can move toward each other under the action of gravity, thereby driving the two brush bodies to clean the opposite sides of the cleaning device respectively.

[0045] The horizontal cross section of the cross beam 1 is a V-shaped structure, and the two brush bodies can move from the high end A toward the low end B of the corresponding running wheel frame 2, so as to facilitate cleaning of the opposite sides of the vehicle body at the same time, thereby improving the cleaning efficiency.

[0046] As an alternative embodiment, see Figure 3 and Figure 4 As shown, the walking wheel frame 2 includes a frame body 21, walking wheels and the above-mentioned brush body driving mechanism 23, wherein: the driving device is drivingly connected to the frame body 21, and is used to pull the frame body 21 back to the high end of the walking track 11; the walking wheel is rotatably connected to the frame body 21, and is rollingly connected to the corresponding walking track 11; the brush body driving mechanism 23 is fixed on the frame body 21, and is drivingly connected to the brush body, and is used to drive the brush body to rotate.

[0047] The running track 11 is a grooved track structure. The running wheels are located in the running track 11. The side walls of the running track 11 prevent the running wheels from falling off.

[0048] The running wheels are rollingly connected to the running track 11 , and the frame 21 can roll along the running track 11 through the running wheels under the action of gravity, thereby reducing movement resistance and facilitating smooth contact between the brush body and the vehicle body.

[0049] As an alternative embodiment, see Figure 3 and Figure 4As shown, the running wheels include an upper running wheel 221 and a lower running wheel 222 both rotatably connected to the frame 21 , the upper running wheel 221 is rollingly connected to the upper portion of the running track 11 , and the lower running wheel 222 is rollingly connected to the lower portion of the running track 11 .

[0050] The upper running wheel 221 and the lower running wheel 222 are respectively connected in a rolling manner to the upper and lower parts of the running track 11 , which can further prevent the running wheel frame 2 from being separated from the running track 11 , thereby ensuring the running stability of the running wheel frame 2 .

[0051] As an alternative embodiment, see Figure 3 As shown, the driving device includes a telescopic cylinder 3 and a traction part, wherein: the telescopic end of the telescopic cylinder 3 is fixedly connected to the traction part, and the traction part is fixedly connected to the walking wheel frame 2. When the telescopic end of the telescopic cylinder 3 is extended, the walking wheel frame 2 can roll toward the lower end of the walking track 11 under the action of gravity. When the telescopic end of the telescopic cylinder 3 is retracted, the walking wheel frame 2 can be pulled back to the upper end of the walking track 11. The traction part includes a cloth belt 4 or a chain or a rope. The traction part of this embodiment is a cloth belt 4. See Figure 3 As shown, the telescopic cylinder 3 is vertically arranged, and the telescopic end of the telescopic cylinder 3 is arranged upward and fixedly connected to the traction part.

[0052] In this embodiment, when the walking wheel frame 2 drives the brush body to contact the equipment to be cleaned, the telescopic cylinder 3 is in an extended state, which will not affect the descent of the walking wheel frame 2 along the walking track 11. When the cleaning work is completed, the telescopic end of the telescopic cylinder 3 is retracted, and the walking wheel frame 2 is pulled back to the high end A of the corresponding walking track 11 through the traction part, so as to facilitate the next cleaning work.

[0053] As an alternative embodiment, see Figure 3 As shown, the driving device also includes a fixed pulley 5, a bracket 6 is fixed to the high end of the walking track 11, the fixed pulley 5 is rotatably connected to the corresponding bracket 6, and the traction part is wound around the fixed pulley 5.

[0054] The traction part is wound around the fixed pulley 5 and can be reversed, thereby connecting the telescopic end of the telescopic cylinder 3 and the walking wheel frame 2.

[0055] The telescopic end of the telescopic cylinder 3 contracts, pulling the traction part, and the fixed pulley 5 rolls, and further pulls the walking wheel frame 2 back to the high end A of the corresponding walking track 11 through the traction part.

[0056] Embodiment 2:

[0057] like Figure 1 As shown, this embodiment provides a car washing device, including a brush body 100 and the brush body running mechanism. The brush body 100 can be a side brush used to clean equipment to be cleaned, such as a car.

[0058] The car washing device of this embodiment has the above-mentioned brush body traveling mechanism, so it also has the advantages of simple structure and low cost.
