[0002] At present, the car washer that can carry out vehicle cleaning work automatically has been gradually popularized in each big city, and for household vehicles, the car washer usually sprays high pressure water to the vehicle surface through the high pressure water washing device located above the vehicle to carry out the cleaning work of the vehicle surface, specifically, in the cleaning work, the vehicle is stationary, and the high pressure water washing device reciprocates along the length direction of the vehicle to fully wash the vehicle.

DETAILED DESCRIPTION

[0034] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The present application will be described in detail below with reference to the drawings and in combination with the embodiments.

[0035] In order to solve the problem that the operation cost of the car washing machine in the prior art is large and affects the car washing experience of customers, the present application provides a flushing device and a car washing machine with the same.

[0036] As Figures 1 to 7As shown, the flushing device is arranged on the driving frame 1 of the car washer, the driving frame 1 is used to drive the flushing device to reciprocate, the flushing device comprises a flushing assembly 10, a first driving structure 20, a first detection assembly 30 and a control structure, the flushing assembly 10 comprises a rotatable flushing structure 11, the flushing structure 11 is used to spray liquid to the vehicle body to flush the vehicle. The first driving structure 20 is drivingly connected with the flushing structure 11, the first driving structure 20 drives the flushing structure 11 to rotate to adjust the spraying direction of the flushing structure 11. The first detection assembly 30 is used to detect whether there is a vehicle body at the preset height. The control structure is connected with the first driving structure 20 and the first detection assembly 30 to control the rotating speed and / or rotating direction of the first driving structure 20 according to the detection value of the first detection assembly 30.

[0037] By applying the technical scheme of the embodiment, the flushing device is arranged on the driving frame 1 of the car washer, the driving frame 1 is used to drive the flushing device to reciprocate, the flushing assembly 10 of the flushing device comprises a rotatable flushing structure 11, the flushing structure 11 is used to spray liquid to the vehicle body to flush the vehicle. The first driving structure 20 is drivingly connected with the flushing structure 11 to drive the flushing structure 11 to rotate to adjust the spraying direction of the flushing structure 11. The first detection assembly 30 is used to detect whether there is a vehicle body at the preset height. The control structure is connected with the first driving structure 20 and the first detection assembly 30 to control the rotating speed and / or rotating direction of the first driving structure 20 according to the detection value of the first detection assembly 30. In this way, the flushing device in the embodiment still actually adopts the traditional reciprocating flushing mode, but the flushing direction of the flushing structure 11 can be adjusted according to the actual working condition, that is, during the reciprocating movement of the flushing device, if the first detection assembly 30 detects that there is no vehicle body at the preset height (that is, it means that the flushing device has moved to the front windshield and the rear windshield, and the front windshield and the rear windshield are arranged obliquely and have a lower height than the roof), the control structure will control the first driving structure 20 to drive the flushing structure 11 to rotate to a corresponding angle, so that the water flow sprayed by the flushing structure 11 can impact on the front windshield and the rear windshield at almost a vertical angle, thereby increasing the flushing pressure of the water flow and improving the flushing effect of the flushing structure. The improvement of the flushing effect means the reduction of the number of repeated flushing (that is, the reduction of the amount of water used for flushing and the length of time for flushing), thereby solving the problems of the car washer in the prior art that the operation cost is large and the customer's car washing experience is affected.

[0038] As Figure 1As shown, the flushing structure 11 is arranged to be liftable, and the flushing device further comprises a second driving structure 40 which is drivingly connected with the flushing structure 11, and the second driving structure 40 drives the flushing structure 11 to perform lifting movement to adjust the distance between the flushing structure 11 and the vehicle body. In this way, the flushing height of the flushing structure 11 can be adjusted according to the specifications and sizes of the vehicle, which on the one hand improves the versatility of the flushing device, and on the other hand ensures that the distance between the flushing structure 11 and the vehicle body is appropriate to further improve the flushing effect of the flushing structure 11.

[0039] Specifically, if the distance between the flushing structure 11 and the vehicle body is too small, the water flow sprayed by the flushing structure 11 will not be fully dispersed before impacting on the vehicle body, which will result in a small flushing area of the flushing structure 11 and the possibility of missing some parts of the vehicle body. If the distance between the flushing structure 11 and the vehicle body is too large, the dispersed water flow will collide and interfere with each other, which will affect the impact pressure of the water flow on the vehicle body. The flushing structure 11 in the embodiment can be lifted and adjusted according to the actual height of the vehicle body to ensure that the distance between the flushing structure 11 and the vehicle body is appropriate.

[0040] As shown in Figures 1 to 3 The preset height is relative to the height of the flushing structure 11, and the first detection assembly 30 comprises a first detection piece 31 and a second detection piece 32 which are arranged at intervals along the movement direction of the flushing device. The first detection piece 31 is used to detect whether there is a vehicle body at the first preset height, and the second detection piece 32 is used to detect whether there is a vehicle body at the second preset height. The first preset height is higher than the second preset height. The control structure is further connected with the second driving structure 40 to control the rotation speed and / or direction of the second driving structure 40 according to the detection value of the first detection assembly 30. In this way, since the preset height in the embodiment is relative to the height of the flushing structure 11, the detection height of the first detection assembly 30 will be adjusted accordingly with the lifting of the flushing structure 11 to adapt to the heights of different vehicles, which further improves the versatility of the flushing device. At the same time, through the cooperation between the first detection piece 31, the second detection piece 32, the first driving structure 20 and the second driving structure 40, the movement trajectory of the flushing structure 11 can be fitted and simulated to the front and rear windshields, which further improves the flushing effect of the flushing structure 11.

[0041] Optionally, the first preset height detected by the first detection member 31 can be determined by the optimal spraying distance of the washing structure 11 (the optimal spraying distance is determined by the specifications and models of the nozzles actually used for spraying), the height difference between the first detection member 31 and the washing structure 11 is the optimal spraying distance of the washing structure 11, and the actual detection height thereof is the highest height of the vehicle body (which can be adapted by the lifting movement), and the second preset height detected by the second detection member 32 is slightly less than the first preset height (detecting the vehicle body below the roof).

[0042] Specifically, the actual movement process is as follows: at the initial spraying, the washing structure 11 is lifted to the detection height of the first detection member 31 and the lowest height of the roof, and the second detection member 32 detects whether there is a vehicle body below the roof at this time (at this time, there should be a vehicle body, and the spraying distance is the optimal spraying distance), and when the washing device moves in the direction from the second detection member 32 to the first detection member 31, when the first detection member 31 cannot detect the vehicle body, it means that the washing device has currently moved to the front windshield (the rear windshield is only different in the reciprocating direction), the washing structure 11 is rotated to a preset angle, and when the second detection member 32 also cannot detect the vehicle body, the washing structure 11 starts to descend until the first detection member 31 detects the vehicle body (front windshield), the descending movement stops, and when the second detection member 32 again cannot detect the vehicle body, the washing structure 11 again descends until the first detection member 31 detects the vehicle body (front windshield), and the above process is repeated until the first detection member 31 and the second detection member 32 can detect the vehicle body (that is, the engine hood of the vehicle in front begins to be washed). The reciprocating linear movement of the washing device cooperates with the lifting movement of the washing structure 11, so that the washing structure 11 presents a stepped movement track, and the movement track is fitted with the inclination of the front windshield, thereby maximizing the washing effect of the washing structure 11.

[0043] In the embodiment, the first detection assembly 30 further comprises a third detection member 33, the first detection member 31, the second detection member 32 and the third detection member 33 are spaced apart along the reciprocating movement direction of the washing device, the second detection member 32 is located between the first detection member 31 and the third detection member 33, and the third detection member 33 is also used for detecting whether there is a vehicle body at the first preset height. In this way, the reciprocating movement of the washing device can make the washing structure 11 fit the inclination angle of the front windshield through the cooperation of the first detection member 31 and the second detection member 32, and the reciprocating movement of the washing device can make the washing structure 11 fit the inclination angle of the rear windshield through the cooperation of the second detection member 32 and the third detection member 33.

[0044] In the embodiment, the first detection member 31, the second detection member 32 and the third detection member 33 are all photoelectric sensors, i.e. the three detection members are capable of detecting whether there is a vehicle body in the plane of the height where the detection member is located.

[0045] Specifically, on the basis of the above control logic, the embodiment can also be further extended to design so that the washing structure 11 is capable of washing the side of the vehicle head and the parking space. Taking the front windshield as an example, after the fitting and lifting action of the washing structure 11 ends, (i.e. until the first detection member 31 and the second detection member 32 can detect the vehicle body, the washing structure 11 starts to wash the front vehicle engine cover), the horizontal movement continues until the first detection member 31 and the second detection member 32 cannot detect the vehicle body, which means that the washing of the front vehicle engine cover by the washing structure 11 has ended. At this time, the washing structure 11 can continue to rotate and overturn to the horizontal state to wash the side of the vehicle head (the license plate surface). It can be seen that the washing device in the embodiment also has a larger washing coverage area.

[0046] As shown in Figures 1 to 4 , the washing device further comprises a second detection assembly 50 for detecting the rotation angle of the washing structure 11. The control structure is further connected with the second detection assembly 50. When the first detection assembly 30 detects that there is no vehicle body at the preset height, the control structure controls the first driving structure 20 to start running to drive the washing structure 11 to rotate. When the second detection assembly 50 detects that the washing structure 11 rotates to the preset angle, the control structure controls the first driving structure 20 to stop running. In this way, through the mutual cooperation between the second detection assembly 50 and the control structure, the automatic control of the rotation angle of the washing structure 11 can be realized, i.e. when the washing structure 11 rotates to the preset angle, the control structure will control the first driving structure 20 to stop running according to the signal sent by the second detection assembly 50.

[0047] As shown in Figures 1 to 5As shown, the flushing assembly 10 further comprises a mounting structure 12, the mounting structure 12 comprises a mounting body 121 and a rotating shaft 122 arranged on the mounting body 121, the flushing structure 11 is rotatably arranged on the mounting structure 12 through the rotating shaft 122, the first driving structure 20 and / or the second detection assembly 50 are arranged on the mounting body 121, the driving end of the first driving structure 20 is connected with the rotating shaft 122, so as to drive the rotating shaft 122 to drive the flushing structure 11 to rotate, the second detection assembly 50 detects the rotating angle of the rotating shaft 122, so as to detect the rotating angle of the flushing structure 11. Wherein, the mounting structure 12 is arranged on the driving frame 1 in a lifting manner, the second driving structure 40 is arranged on the driving frame 1 and is drivingly connected with the mounting structure 12, so as to drive the mounting structure 12 to drive the flushing structure 11 to perform lifting movement. In this way, the arrangement of the mounting structure 12 provides a mounting basis for the rotating movement of the flushing structure 11, and on the other hand, the lifting movement of the flushing structure 11 is realized through the lifting movement of the mounting structure 12. At the same time, the first driving structure 20 and the second detection assembly 50 are arranged on the mounting structure 12, so that they can also be lifted synchronously, thereby reducing the driving connection difficulty of the first driving structure 20 and the detection arrangement difficulty of the second detection assembly 50.

[0048] In the embodiment, the flushing structure 11 comprises a columnar mounting shell 111 and a spraying member 112, the mounting shell 111 has a mounting cavity and an avoiding hole in communication with the mounting cavity, the mounting cavity is used for mounting the spraying member 112 (corresponding liquid conveying pipeline) to protect the spraying member 112 and the liquid conveying pipeline, and the avoiding hole is used for the spraying member 112 to extend out of the mounting cavity.

[0049] In the embodiment, the columnar mounting shell 111 spans above the vehicle body.

[0050] In the embodiment, the mounting structure 12 is actually two, that is, one mounting structure 12 is arranged at each end of the mounting shell 111, and the rotating shafts 122 of the two mounting structures 12 are respectively connected with the two ends of the mounting shell 111.

[0051] In the embodiment, the mounting body 121 is formed by bending or welding a plurality of plate-shaped members, and the specific structure thereof is not limited and can be adjusted according to actual structure requirements.

[0052] In the embodiment, the flushing assembly 10 further comprises a mounting frame 13, the mounting frame 13 is arranged in a ring shape and is arranged on the mounting structure 12 to synchronously lift with the mounting structure 12, and the first detection assembly 30 is arranged on the mounting frame 13, that is, the relative height between the first detection assembly 30 and the mounting structure 12 is always unchanged.

[0053] Specifically, the mounting racks 13 are two, and are arranged in one-to-one correspondence with the two mounting structures 12 to respectively mount the light beam emitting member and the light beam blocking member of the photoelectric sensor (i.e. to block the judgment of the presence of the vehicle body).

[0054] As shown in Figures 3 to 5 The first driving structure 20 and the second detection assembly 50 are both arranged on the mounting body 121, i.e. the first driving structure 20 is arranged on the mounting body 121 of the mounting structure 12 at one end of the mounting shell 111, and the second detection assembly 50 is arranged on the mounting body 121 of the mounting structure 12 at the other end of the mounting shell 111.

[0056] Optionally, the first driving member 21 is a motor member.

[0057] Optionally, the first driving member 21 can comprise a motor member and a speed reducer.

[0058] As shown in Figure 5As shown, the second detection assembly 50 includes the fourth detection member 51 and the fifth detection member 52 arranged side by side, and the rotating shaft member 122 at one end of the second detection assembly 50 is a cooperating rotating shaft member, which has two sets of cooperating protrusions, corresponding to the two detection members (the fourth detection member 51 and the fifth detection member 52), and each set of cooperating protrusions includes two cooperating protrusions 1221 arranged at intervals along the circumference of the cooperating rotating shaft member. One of the two cooperating protrusions 1221 in one set of cooperating protrusions is used to control the rotation angle of the washing structure 11, i.e., when the washing device moves to the front windshield, the washing structure is rotated (the rotating shaft member 122 rotates accordingly) under the drive of the first driving member 21, until one of the cooperating protrusions 1221 in this set of cooperating protrusions moves to opposite the detection end of the detection member (one of the fourth detection member 51 and the fifth detection member 52) corresponding thereto, which indicates that the washing structure 11 is rotated to the right position (output signal, the control structure controls the first driving member 21 to stop rotating). The other cooperating protrusion 1221 in the other set of cooperating protrusions is used to determine whether the washing structure is reversed (the washing device moves to the rear windshield) to the right position. The two cooperating protrusions 1221 in the other set of cooperating protrusions are used to reset the washing structure 11 after the washing is completed at the front and rear windshields, i.e., after the washing at the front and rear windshields is completed, when the cooperating protrusion 1221 in this set of cooperating protrusion components moves to opposite the detection member (the other of the fourth detection member 51 or the fifth detection member 52), it indicates that the washing structure 11 is reset successfully (output signal, the control structure controls the first driving member 21 to stop rotating), and the two cooperating protrusions 1221 are respectively used to reset the positive rotation or the reverse rotation to reduce the reset rotation angle and improve the reset speed.

[0059] Optionally, the fourth detection member 51 and the fifth detection member 52 are distance sensors.

[0060] Optionally, the cooperating protrusions 1221 can be directly machined on the surface of the rotating shaft member 122, such as by machining threaded holes and fastening screws to form the cooperating protrusions 1221.

[0061] Optionally, the control structure is an encoder, and its setting position is not limited, such as a cylindrical encoder integrated on the rotating shaft member 122, or separately arranged at other positions and connected through a line.

[0062] As Figure 1As shown, the second driving structure 40 comprises a traction assembly 41 and a second driving member 42, the traction assembly 41 comprises a rotating wheel member 411 and a flexible traction member wound on the rotating wheel member 411, and a free end of the flexible traction member is connected with the mounting body 121. The second driving member 42 is in driving connection with the rotating wheel member 411, and the second driving member 42 is used to drive the rotating wheel member 411 to rotate, so as to drive the washing structure 11 to move up and down in the process of winding and unwinding the flexible traction member.

[0066] In the embodiment, the second driving structure 40 further comprises a transmission shaft 43, and the second driving member 42 is in driving connection with the rotating wheel members 411 of the two groups of traction assemblies 41 through the transmission shaft 43, so as to simultaneously drive the two rotating wheel members 411 to rotate, thereby ensuring that the two rotating wheel members 411 have high rotation consistency.

[0067] As shown in the drawings, Figure 1 The washing device further comprises a guide assembly 60, the guide assembly 60 comprises a roller member 61 and a guide rail member 62, and the roller member 61 is rotatably arranged on the mounting structure 12. The guide rail member 62 is arranged on the driving frame 1, and the guide rail member 62 has a guide recess 621 extending along the up and down direction of the washing structure 11. At least part of the roller member 61 is located in the guide recess 621, so as to guide the up and down movement direction of the washing structure 11 through the limiting stop between the roller member 61 and the guide recess 621. In this way, the above arrangement improves the up and down stability of the washing structure 11 through the limiting stop between the roller member 61 and the guide rail member 62. Meanwhile, the arrangement of the roller member 61 can also reduce the friction and prolong the service life.

[0068] As shown in the drawings, Figure 1 , Figure 2 , Figure 6 and Figure 7As shown, the flushing device further comprises an anti-collision assembly 70 arranged on the flushing structure 11, which is used to detect whether there is a vehicle body within a preset range. The control structure is connected with the second driving structure 40 and the anti-collision assembly 70, so as to control the rotating speed and / or direction of the second driving structure 40 according to the detection value of the anti-collision assembly 70. In this way, the anti-collision assembly 70 can play a guarantee role to avoid the detection member from malfunctioning or being damaged, so that the flushing structure 11 does not continuously descend and hit the vehicle body, thereby guaranteeing the safety of the vehicle of the customer and avoiding unnecessary loss.

[0069] As shown in Figure 6 and Figure 7 The anti-collision assembly 70 comprises a detection structure 71, a shielding member 72, an elastic trigger strip 73 and an elastic member 74. The detection structure 71 has spaced detection ends 711, mounting protrusions 712 and first connecting protrusions 713. The shielding member 72 has spaced strip-shaped matching holes 721 and second connecting protrusions 722. The mounting protrusions 712 extend into the strip-shaped matching holes 721 to mount the shielding member 72 on the detection structure 71. The shielding member 72 can slide along the extension direction of the strip-shaped matching holes 721 and can rotate around the mounting protrusions 712. The elastic trigger strip 73 is connected with the shielding member 72 to drive the shielding member 72 to move. The elastic members 74 are arranged between the ends of the elastic trigger strip 73 and the first connecting protrusions 713, between the first connecting protrusions 713 and the second connecting protrusions 722, and between the second connecting protrusions 722 and the mounting protrusions 712. The shielding member 72 has a shielding position and a avoiding position. When the elastic trigger strip 73 collides with the vehicle body to be elastically deformed, the elastic trigger strip 73 drives the shielding member 72 to move to the avoiding position, and the shielding member 72 avoids the detection ends 711. When the elastic trigger strip 73 is separated from the vehicle body, the elastic members 74 reset the elastic trigger strip 73 to be arc-shaped to surround a preset range. In this way, the above-mentioned arrangement can realize the range detection function of the anti-collision assembly 70, and can reduce the cost of the anti-collision assembly 70 (i.e., a conventional visual detection device is not used).

[0070] In the embodiment, the detection structure 71 comprises a mounting plate 714 and a sixth detection member 715. The mounting plate 714 is fixedly mounted on the flushing structure 11, and the sixth detection member 715 is arranged on the mounting plate 714 and forms the detection end 711.

[0071] In the embodiment, the mounting protrusion 712 is one, the first connecting protrusions 713 are two, and the three are arranged in an isosceles triangle (the two first connecting protrusions 713 are symmetrical to each other), the detection end 711 is located at the center of the isosceles triangle, and the second connecting protrusion 722 coincides with the detection end 711. The shielding member 72 is a strip-shaped plate, and one end of the strip-shaped fitting hole 721 is located between the other end and the second connecting protrusion 722 (preferably, the distance between the one end of the strip-shaped fitting hole 721 away from the second connecting protrusion 722 and the other end is consistent with the distance between the mounting protrusion 712 and the detection end 711).

[0072] In the embodiment, the elastic member 74 is a spring.

[0073] Specifically, under the action of the spring elasticity, the special arrangement of the mounting protrusion 712, the first connecting protrusion 713, the detection end 711, the strip-shaped fitting hole 721, and the second connecting protrusion 722 can cause the elastic trigger strip 73 to bend and maintain an arc shape (approximately a circular arc shape, and the central axis is parallel to the rotation axis of the washing structure 11) when not triggered. The elastic trigger strip 73 arranged in this way can still maintain an effective detection range (the detection range of the circular arc-shaped elastic trigger strip 73 is still the edge of the elastic trigger strip 73 even when rotating) during the rotation of the washing structure 11, so that the anti-collision assembly 70 has high detection reliability.

[0074] Specifically, when the elastic trigger strip 73 is impacted or pressed at any position, the local deformation will act on the shielding member 72 under the action of the elastic restoring force of the elastic trigger strip 73 and the elastic deformation of the spring. After the shielding member 72 moves, it no longer shields the detection end 711. At this time, it can be judged that the lowering distance of the washing structure 11 is too large, and the second driving structure 40 needs to be immediately controlled to stop running.

[0075] In the embodiment, the shielding member 72 includes a shielding body and a connecting plate. The shielding body has the strip-shaped fitting hole 721 and the second connecting protrusion 722 and is used to shield the detection end 711. The connecting plate is fixedly connected with the elastic trigger strip 73. The shielding body and the connecting plate are rotatably connected to increase the movable range of the shielding body and further improve the detection reliability of the anti-collision assembly 70.

[0076] The washing device in the embodiment has at least the following advantages:

[0077] 1. Large coverage and high universality. Compared with the traditional fixed washing device, the washing structure 11 in the embodiment can not only rotate and adjust the washing angle to cover a larger vehicle body area (such as being turned to a horizontal state to wash the front of the vehicle head and tail), but also can perform lifting movement to adapt to vehicles of different heights.

[0078] 2、The washing effect is excellent, the multi-angle operation (washing angle adjustment) function and the motion track simulation function of the washing structure 11 can increase the washing pressure to overcome stubborn stains on the surface of the vehicle body;

[0079] 3、The washing efficiency is high, so as to reduce the operation cost of the car washing machine and shorten the cleaning time, that is, with the improvement of the washing effect, the reciprocating washing times can be reduced, the washing time can be effectively saved, and the waiting time of customers is reduced;

[0080] 4、A certain anti-clogging capability, that is, in the rotating process of the washing structure 11, the liquid delivery pipeline and the spray part 112 can rotate with the rotation, so as to avoid the problem of impurity accumulation caused by long-term fixed-angle spraying;

[0081] 5、Automatic obstacle avoidance function, the profile of the vehicle to be washed can be recognized by the anti-collision assembly 70 cooperating with the multiple detection parts, and the anti-collision assembly 70 can automatically ascend and descend when encountering obstacles, so as to avoid collision.

[0082] The embodiment also provides a car washing machine (not shown), which comprises a driving frame 1 and a washing device, the driving frame 1 can reciprocate along a preset direction, the washing device is arranged on the driving frame 1, and the washing device is the washing device described above.

[0083] Specifically, the driving frame 1 is actually slidably arranged on a car washing machine main body of the car washing machine, and a corresponding driving device is used to drive the driving frame 1 to reciprocate, so as to drive the washing device located on the driving frame 1 to reciprocate.

[0084] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

[0085] The flushing device is arranged on a driving frame of the car washer, and the driving frame is used to drive the flushing device to move back and forth. The flushing assembly of the flushing device comprises a rotatable flushing structure, which is used to spray liquid on the vehicle body to flush the vehicle. A first driving structure is drivingly connected with the flushing structure, so as to adjust the spraying direction of the flushing structure by driving the flushing structure to rotate. A first detection assembly is used to detect whether the vehicle body exists at a preset height. A control structure is connected with the first driving structure and the first detection assembly, so as to control the rotating speed and / or direction of the first driving structure according to the detection value of the first detection assembly. In this way, the flushing device in the present application still adopts the traditional flushing mode of reciprocating, but the flushing direction of the flushing structure can be adjusted according to the actual working condition. That is, during the reciprocating movement of the flushing device, if the first detection assembly detects that the vehicle body does not exist at the preset height (which means that the flushing device has moved to the front windshield and the rear windshield, which are arranged in an inclined manner and have a lower height than the roof of the vehicle), the control structure will control the first driving structure to drive the flushing structure to rotate to a corresponding angle, so that the water flow sprayed by the flushing structure can impact on the front windshield and the rear windshield at a nearly vertical angle, thereby increasing the flushing pressure of the water flow and improving the flushing effect of the flushing structure. The improvement of the flushing effect means that the number of repeated flushing times is reduced (i.e. the amount of water used for flushing and the length of time for flushing is reduced), thereby solving the problem of high operation cost and affecting the customer's experience of the car washer in the prior art.
