The bar 235, the elastic member 236, and the control unit (not shown) may control the operation of the injection apparatus 220 according to whether the detection signal generated by the second detection sensor 231 is received.

The second detection sensor 231 is installed in combination with the housing 221 by a mount 237a provided on the inner wall of the housing 221, and detects a detection object by magnetic force.

The second detection sensor 231 detects a metal, and a non-contact sensor or a proximity sensor may be applied, and when a detection object is detected, a light emitting diode (LED) is mounted therein so that a manager can visually check the detection object. Can be.

In addition, the second detection sensor 231 may recognize the detection object by magnetic force and transmit a detection signal corresponding thereto to the controller (not shown). Here, the detection object may include a metal mover 233 inserted into the spacer 232 which will be described later.

The spacer 232 may be disposed inside the housing 221 and may be installed to maintain a constant distance from the second detection sensor 231. Here, the predetermined interval may be set within a range within the maximum sensing distance of the second sensing sensor 231.

The spacer 232 may be formed of a material that is not affected by magnetic force, that is, nonmetallic and nonmagnetic material so that the second sensing sensor 231 cannot recognize it. For example, the spacer 232 may be made of a plastic material, but the scope of the present invention is not necessarily limited thereto.

The spacer 232 is provided to a size that can be accommodated in the housing 221, preferably, the diameter of the spacer 232 may be smaller than the inner diameter of the housing 221.

In addition, the spacer 232 may be formed in a polygonal or circular shape, but the shape is not particularly limited.

Meanwhile, an insertion hole 232a is formed at one side of the spacer 232 to insert the metal mover 233. Here, one side is defined as an area overlapping each other with the second detection sensor 231 in the longitudinal direction of the housing 221 (hereinafter, referred to as "a recognition area of the second detection sensor 231 for convenience"), preferably It may be located in the center of the spacer 232.

The metal mover 233 may be inserted into the insertion hole 232a and protrude outwardly of the spacer 232. In this case, an example of the metal mover 233 may be a metal bolt.

The collision recognizing unit 234 may directly contact or collide with the to-be-cleaned vehicle when the first first sensor 210 malfunctions or an obstacle that is not recognized is attached to the to-be-cleaned vehicle.

The collision recognition unit 234 may be provided outside the housing 221, and may be formed to be spaced apart from the outer wall of the housing 221 at regular intervals. That is, the diameter of the collision recognizing unit 234 may be larger than the outer diameter of the housing 221 to protect the housing 221 from collision with the vehicle to be cleaned.

The collision recognition unit 234 is preferably provided in a circular shape so as to prevent damage or damage of the vehicle to be cleaned, but the shape is not particularly limited. In addition, an outer circumferential surface of the collision recognizing unit 234 may be further provided with an absorbing member (not shown) for cushioning the impact when the vehicle is in contact with or to be impacted. Absorbing member (not shown) is formed to correspond to the shape of the collision recognition unit 234, it is possible to apply a rubber material to the buffer action.

The connection bar 235 may support the collision recognition unit 234 and the spacer 232.

One end of the connection bar 235 is coupled to the spacer 232, and the other end extends through the through hole 221b formed on the upper and / or side surfaces of the housing 221 to extend outside of the housing 221 to recognize a collision. Coupled to the portion 234.

The connecting bar 235 is provided in plurality so as to prevent the spacer 232 from being separated to the other side when the housing 221 rotates and / or lifts, so as to maintain a balance with the collision recognition unit 234. Can be prepared.

The plurality of connection bars 235 may be arranged to be spaced apart from each other in the circumferential direction of the collision recognition unit 234 around the spacer 232, and may be provided in a radial shape with respect to the spacer 232.

The plurality of connection bars 235 may be provided in the same number as the through holes 221b formed on the top and / or side surfaces of the housing 221, and the plurality of connection bars 235 adjacent to each other may be arranged at equal intervals. .

In this case, the plurality of connection bars 235 may not be formed through the lower surface of the housing 221. The reason is that when at least one through hole 221b is formed on the bottom surface of the housing 221 on which the plurality of injection holes 221a are formed, the washing water or the washing liquid is sprayed in the drying process after spraying the washing water or the washing liquid. This is because it can fall into this to-be-cleaned vehicle. Therefore, it is preferable that the injection hole 221a to the through hole 221b are not formed so that the lower surface of the housing 221 can be sealed.

The elastic member 236 may support the movement of the spacer 232 by elastic force or restoring force.

One end of the elastic member 236 is fixed to the bracket 237b installed on the inner wall of the housing 221, the other end is fixed to the spacer 232, for example, a spring may be applied.

A plurality of elastic members 236 may be provided to maintain a fixing force between the housing 221 and the spacer 232, and may be disposed to avoid interference with the plurality of connection bars 235.

When the collision recognition unit 234 contacts or collides with the vehicle to be cleaned, the elastic member 236 may move the spacer 233 coupled with the collision recognition unit 24 to the other side by an elastic force. Accordingly, the metal mover 233 inserted into the insertion hole 233a of the spacer 233 is out of the recognition area of the second detection sensor 231, and the second detection sensor 231 is the metal mover 233. ) Is not recognized anymore, so the detection signal cannot be transmitted to the controller (not shown).

If the vehicle to be cleaned is separated from the collision recognition unit 234, the elastic member 236 moves (or returns) the spacer 233 to one side of the recognition region of the second detection sensor 231 by a restoring force, The second detection sensor 231 may recognize the metal mover 233 by magnetic force and transmit a detection signal to a controller (not shown).

As such, the elastic member 236 supports the movement of the spacer 232 by using the elastic force or the restoring force according to contact or collision between the collision recognition unit 234 and the vehicle to be cleaned.

The controller (not shown) may control the operation of the injection apparatus 220 according to whether the detection signal generated by the second detection sensor 231 is received.

The controller (not shown) may configure a circuit such that a light emitting diode (LED) mounted on the second sensing sensor 231 is turned on when receiving the sensing signal. That is, the manager may visually inspect whether the collision detection device 230 is in contact with the vehicle to be washed or whether there is a collision by turning on the LED.

On the other hand, when the control unit (not shown) does not receive the detection signal, the collision detection device 230 and the to-be-cleaned vehicle are considered to be in contact with or collided with each other, the power applied to the driving means 223 and the lifting means 224 By blocking the operation of the injection device 220 can be forcibly stopped. Therefore, since no further washing operation is performed as the activated car wash device 200 is urgently stopped, the collision between the car to be washed and the car washing device 200 can be prevented, so that the car to be cleaned and the car washing device 200 are prevented. It can be prevented from being damaged or broken.

As described above with reference to the embodiment, only a few are described, but various other forms of implementation are possible. Technical contents of the above-described embodiments may be combined in various forms, unless the technology is incompatible with each other, and may be implemented in a new embodiment.

It is apparent to those skilled in the art that the present invention can be embodied in other specific forms without departing from the spirit and essential features of the present invention. Accordingly, the above detailed description should not be construed as limiting in all aspects and should be considered as illustrative. The scope of the invention should be determined by reasonable interpretation of the appended claims, and all changes within the equivalent scope of the invention are included in the scope of the invention.
