[0004] However, the washing effect of the fixed chassis washing device is actually poor, which is mainly due to the following two reasons:

As for the actual car washing process, the driving speed of the vehicle during washing is much higher than the driving speed required for washing, so it is impossible to perform sufficient spraying and washing.

[0006] 2. The washing effect for large-specification vehicles (with larger chassis size) is poor. Although the spraying and washing are large-area, the washing force of the water flow decreases with the distance from the spraying position. Moreover, due to the fixed spraying direction, the existing fixed chassis washing device cannot perform targeted spraying on the edge of the chassis (close to the tire, easy to splash dirt) where stubborn dirt is prone to accumulate, and the above-mentioned position is actually the smallest under the impact of the water flow, so the spraying and washing effect is poor.

[0031] 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.

[0032] In order to solve the problem of poor chassis flushing effect of the chassis cleaning device of the car washer in the prior art, the present application provides a flushing device and a car washer with the same.

[0033] As Figures 1 to 4As shown, the flushing device is arranged below the chassis of the vehicle for flushing the chassis, and comprises a bearing structure 10, a spraying assembly 20 and a driving structure 30. The bearing structure 10 is movably arranged along a preset direction S. The spraying assembly 20 is arranged on the bearing structure 10 and comprises a first nozzle structure 21 and a second nozzle structure 22. The first nozzle structure 21 is rotatably arranged to spray liquid to the chassis during rotation. The second nozzle structure 22 is rotatably arranged to adjust the spraying direction of the second nozzle structure 22 during rotation of the second nozzle structure 22. The rotation axis of the first nozzle structure 21 and the rotation axis of the second nozzle structure 22 are arranged at an angle. The driving structure 30 is drivingly connected with the bearing structure 10 to drive the bearing structure 10 to drive the spraying assembly 20 to reciprocate along the preset direction S.

[0034] By using the technical scheme of the embodiment, the flushing device is arranged below the chassis of the vehicle for flushing the chassis. The bearing structure 10 of the flushing device is movably arranged along a preset direction S. The spraying assembly 20 is arranged on the bearing structure 10 and comprises a first nozzle structure 21 and a second nozzle structure 22. The first nozzle structure 21 is rotatably arranged to spray liquid to the chassis during rotation. The second nozzle structure 22 is rotatably arranged to adjust the spraying direction of the second nozzle structure 22 during rotation of the second nozzle structure 22. The rotation axis of the first nozzle structure 21 and the rotation axis of the second nozzle structure 22 are arranged at an angle. The driving structure 30 is drivingly connected with the bearing structure 10 to drive the bearing structure 10 to drive the spraying assembly 20 to reciprocate along the preset direction S. Thus, the embodiment first uses a spraying mode of active motion, i.e. the driving structure 30 drives the bearing structure 10 to drive the spraying assembly 20 to repeatedly move to repeatedly flush the chassis of the vehicle, so that the overall flushing effect can be ensured. For each flushing process, the spraying assembly 20 used for spraying liquid to flush comprises two different spraying structures (i.e. the first nozzle structure 21 and the second nozzle structure 22). The first nozzle structure 21 (e.g. a rotating nozzle) can rotate to spray liquid, which can ensure a large spraying area and also make the liquid flow have a certain tangential force when impacting the chassis, so that the flushing effect is better. The second nozzle structure 22 can be rotated to adjust the spraying direction, so as to locally spray the edge of the chassis where the first nozzle structure 21 has a poor flushing effect. The combination of the two ensures that the single spraying effect of the spraying assembly 20 is also good, so that the chassis of the vehicle can be flushed clean, thereby solving the problem of poor flushing effect of the chassis cleaning device of the car washer in the prior art. At the same time, since the single spraying effect of the spraying assembly 20 is good, the number of repeated spraying is small, i.e. the flushing device of the embodiment takes a short time to flush a single vehicle and has high efficiency.

[0035] Optionally, the first nozzle structure 21 is a rotating nozzle, and the second nozzle structure 22 is a universal nozzle.

[0036] In the embodiment, the preset direction S is the length direction of the vehicle.

[0037] Specifically, the washing device in the embodiment is actually arranged in the recess of the foundation and is located below the ground as a whole, so that a large enough spraying distance is ensured between the nozzles and the vehicle chassis, thereby improving the spraying effect.

[0038] In the embodiment, the rotation axis of the first nozzle structure 21 is perpendicular to the horizontal plane, and the rotation axis of the second nozzle structure 22 is perpendicular to the rotation axis of the first nozzle structure 21.

[0039] As shown in FIGS. 1 and 2, Figure 1 and Figure 3 The carrying structure 10 includes a main body 11 and a cover 12. The main body 11 has a mounting cavity for mounting the spraying assembly 20. The cover 12 is arranged on the main body 11 and has first and second avoiding holes 121 and 122 arranged at intervals. The first avoiding hole 121 is used for allowing at least part of the first nozzle structure 21 to extend out of the mounting cavity, and the second avoiding hole 122 is used for allowing at least part of the second nozzle structure 22 to extend out of the mounting cavity. In this way, the cover 12 can protect most of the nozzle structure which is relatively weak in structure, thereby prolonging the service life of the first nozzle structure 21 and the second nozzle structure 22.

[0040] In the embodiment, the main body 11 is actually a frame structure, and the inner cavity of the frame structure constitutes the mounting cavity.

[0043] In the embodiment, the first nozzle structure 21 is three, and the three first nozzle structures 21 are arranged at intervals along the width direction of the frame structure.

[0044] In the embodiment, the second nozzle structure 22 is two, and the two second nozzle structures 22 are arranged at intervals along the width direction of the frame structure and are located on both sides of the three first nozzle structures 21.

[0045] It should be noted that the number of first nozzle structures 21 and second nozzle structures 22 is not limited to this, and can be adjusted according to the working conditions and use requirements. Optionally, the first nozzle structure 21 is one, or two, or four, or five, or six, or more. Optionally, the second nozzle structure 22 is three, or four, or five, or six, or seven, or more.

[0046] Specifically, the second nozzle structure 22 should be at least two to synchronize the washing at the two side edges of the vehicle chassis.

The guide rail structure 50 extends along the preset direction S, and the carrying structure 10 is slidably arranged on the washing working surface through the guide rail structure 50. In this way, the above-mentioned arrangement achieves the transmission connection between the driving structure 30 and the carrying structure 10 through the first transmission chain assembly 40, and the movement direction of the carrying structure 10 can be guided through the guide rail structure 50.

[0048] In this embodiment, the washing working surface is actually the mounting surface in the foundation recess.

[0049] In this embodiment, the main body 11 is also provided with a pulley 14 that can rotate. The pulley 14 cooperates with the guide rail structure 50 to realize the guiding function of the guide rail structure 50.

[0050] In this embodiment, the carrying structure 10 has a connecting portion 13, the first transmission chain assembly 40 includes a driving wheel structure 41, a driven wheel structure 42, and a transmission chain structure 43.

[0052] It should be noted that the specific connection method between the connecting portion 13 and the transmission chain structure 43 is not limited, such as clamping, welding, and other connection methods suitable for chains.

The first rotating shaft member 423 can drive the first driven wheel 421 to move towards or away from the first driving wheel 411 to adjust the distance between the first driving wheel 411 and the first driven wheel 421. In this way, the staff can realize the tensioning of the transmission chain structure 43 by operating the first rotating shaft member 423 to move, so as to avoid that the long transmission chain structure 43 is elongated and falls off in the long-term use process, thereby improving the meshing reliability between the transmission chain structure 43 and the transmission wheel.

[0057] As shown in Figure 3 , the support member 422 has two guide holes 4221 arranged oppositely, the guide holes 4221 are used for allowing the first rotating shaft member 423 to pass through, and the guide holes 4221 are in strip shape, so that the movement direction of the first rotating shaft member 423 is guided by the limiting stop between the hole wall of the guide hole 4221 and the first rotating shaft member 423 in the process that the first rotating shaft member 423 moves close to or away from the first driving wheel 411. In this way, the guide hole 4221 not only preliminarily supports the first rotating shaft member 423, but also provides a certain movement space and performs corresponding guidance, so as to realize the movement function of the first rotating shaft member 423 and guide the movement direction of the first rotating shaft member 423.

[0058] In the embodiment, the support member 422 is actually composed of two symmetrically arranged plate-shaped structures, each plate-shaped structure comprises a first plate segment, a second plate segment and a third plate segment which are sequentially bent, the two adjacent plate segments are arranged at 90°, the third plate segment is used for realizing the mounting of the plate-shaped structure, that is, the plate-shaped structure is fixed in the foundation recess by penetrating fasteners, and the guide hole 4221 is arranged on the second plate segment.

[0059] In the embodiment, the third plate segment and the second plate segment are further provided with an opening 4223, the opening 4223 is communicated with the guide hole 4221, and the first rotating shaft 423 can be installed into the guide hole 4221 through the opening 4223.

[0060] In the embodiment, the first rotating shaft 423 is further provided with a guide protrusion 4231, the support 422 is provided with a corresponding guide plate 4224, the guide plate 4224 is provided with a strip-shaped guide hole, and the guide protrusion 4231 extends into the strip-shaped guide hole to further guide the movement of the first rotating shaft 423.

[0061] As shown in Figure 1 and Figure 4 , the support 422 further has a mounting portion 4222, and the driven wheel structure 42 further includes an adjusting member 424, the adjusting member 424 includes a ring-shaped portion 4241 and a threaded portion 4242, the ring-shaped portion 4241 is sleeved on the first rotating shaft 423. The threaded portion 4242 is threaded on the mounting portion 4222 and is in threaded cooperation with the mounting portion 4222, the threaded portion 4242 is connected with the ring-shaped portion 4241, when the threaded portion 4242 is rotated, the threaded portion 4242 drives the ring-shaped portion 4241 to move relative to the mounting portion 4222, so as to drive the first rotating shaft 423 to move. Among them, the adjusting member 424 is at least two, the ring-shaped portion 4241 of at least one adjusting member 424 is sleeved on one end of the first rotating shaft 423, and the ring-shaped portion 4241 of at least another adjusting member 424 is sleeved on the other end of the first rotating shaft 423, and the mounting portion 4222 is at least two, at least two mounting portions 4222 are provided in one-to-one correspondence with at least two adjusting members 424. In this way, the above-mentioned setting realizes the tensioning adjustment movement of the first rotating shaft 423 through the adjusting member 424 on the one hand; on the other hand, it makes the structure of the adjusting member 424 simpler, easier to process and realize, and further reduces the processing cost of the flushing device. At the same time, the number of adjusting members 424 realizes the synchronous adjustment of the two ends of the first rotating shaft 423, so as to avoid its deflection, and further improves the meshing reliability between the transmission chain structure 43 and the first driven wheel 421.

[0062] In the embodiment, the mounting portion 4222 is a mounting plate provided on the support 422 and a nut structure fixed on the mounting plate, and the threaded portion 4242 is a screw rod to be in threaded cooperation with the nut structure.

[0063] Specifically, the first rotating shaft 423 is further sleeved with a bearing structure, and the first driven wheel 421 is sleeved on the bearing structure to realize rotation.

[0064] As shown in Figure 1 and Figure 3As shown, the first transmission chain assembly 40 further comprises a support structure 44, which is located between the driving wheel structure 41 and the driven wheel structure 42, and has a roller member 441 rotatably arranged for supporting the transmission chain structure 43. In this way, the above arrangement can further support the transmission chain structure 43 which has a relatively long length and a relatively large mass, so as to ensure that the transmission chain structure 43 can stably transmit power.

[0065] Specifically, the support structure 44 is actually a chain bracket.

[0066] As shown, Figure 1 As shown, the spraying assembly 20 further comprises a tubular structure, a pump structure and a drag chain structure 23, the pump structure is in communication with the first nozzle structure 21 and the second nozzle structure 22 through the tubular structure, so as to supply liquid to the first nozzle structure 21 and the second nozzle structure 22. At least a part of the tubular structure is a flexible structure, the tubular structure deforms during the movement of the spraying assembly 20 driven by the bearing structure 10, and the drag chain structure 23 is sleeved on the tubular structure for protecting the tubular structure. In this way, the above arrangement can realize the liquid spraying function of the first nozzle structure 21 and the second nozzle structure 22 through the tubular structure and the pump structure, and can also protect the tubular structure through the drag chain structure 23, so as to prolong the service life of the spraying assembly 20.

[0067] In the embodiment, the pump structure can be a high-pressure water pump, so as to supply high-pressure water liquid to the first nozzle structure 21 and the second nozzle structure 22.

[0068] Optionally, the flushing device further comprises a control structure and a first detection member, the first detection member is used for detecting whether the bearing structure 10 and / or the spraying assembly 20 exists at the preset position, and the control structure is connected with the first detection member and the driving structure 30, so as to control the rotating speed and / or the rotating direction of the driving structure 30 according to the detection value of the first detection member. In this way, the above arrangement actually realizes the reciprocating cleaning motion in the fixed driving, which can simplify the control process and reduce the processing cost.

[0070] Optionally, the flushing device further comprises a control structure and a second detection member, the second detection member is arranged on the bearing structure 10 and moves synchronously with the bearing structure 10, and is used for detecting whether the bottom plate exists above the bearing structure 10, and the control structure is connected with the second detection member and the driving structure 30, so as to control the rotating speed and / or the rotating direction of the driving structure 30 according to the detection value of the second detection member. In this way, the above arrangement actually makes the movement stroke (i.e. the spraying stroke) of the bearing structure 10 match the length of the bottom plate, so as to adapt to different vehicle lengths.

[0071] Optionally, the second detection member is an infrared sensor, that is, when the infrared sensor output beam blocked by the vehicle chassis is no longer blocked, it is judged that the bearing structure 10 has completed a complete cleaning of the vehicle chassis, and the control structure controls the driving member 31 to reverse to perform reciprocating spraying.

[0072] The flushing device in the embodiment has at least the following advantages:

[0073] 1. High universality, the spraying direction of the second nozzle structure 22 can be adjusted according to the size of the vehicle to be flushed to achieve the most suitable flushing effect;

[0074] 2. Good flushing effect, the reciprocating flushing can be performed at the same time, and the cleaning effect is 3-5 times that of the traditional fixed chassis flushing device;

[0077] Specifically, the operation process of the car washing machine is as follows:

[0078] After the vehicle stops in the designated area, the photoelectric sensor of the car washing machine transmits a signal to the control structure (PLC control module) and feeds back to the driving structure 30, the driving structure 30 is positively rotated and drags the bearing structure 10 to move, the pump structure is started synchronously, and the spraying flushing action is started. Until the first detection member triggers the corresponding signal, the driving structure 30 reverses, drags the bearing structure 10 to move back, until the bearing structure 10 is reset to the initial position, the driving structure 30 is positively rotated again, and then the reciprocating flushing action is realized.

[0079] From the above description, it can be seen that the above-mentioned embodiments of the utility model realize the following technical effects:

An angle is formed between the rotation axis of the first nozzle structure and the rotation axis of the second nozzle structure. A driving structure is drivingly connected with the bearing structure to drive the bearing structure to drive the spraying assembly to reciprocate along the preset direction S. In this way, the spraying mode of active motion is first adopted, i.e., the driving structure drives the bearing structure to drive the spraying assembly to repeatedly move to repeatedly flush the chassis of the vehicle, so that the overall flushing effect can be ensured. For each flushing process, the spraying assembly used to spray liquid to flush is provided with two different spraying structures (i.e., the first nozzle structure and the second nozzle structure). The first nozzle structure (e.g., a rotating nozzle) can perform rotary spraying, which can ensure a large spraying area and also make the liquid flow generate a certain tangential force during impact on the chassis, so that the flushing effect is better. The second nozzle structure can be rotated and the spraying direction can be adjusted according to the size of the chassis, so as to locally and importantly spray the edge of the chassis where the flushing effect of the first nozzle structure is poor. The combination of the two ensures that the single spraying effect of the spraying assembly is also better, so that the chassis of the vehicle can be flushed relatively clean, thereby solving the problem of poor flushing effect of the chassis cleaning device of the car washing machine in the prior art. At the same time, since the single spraying effect of the spraying assembly is better, the number of repeated spraying is actually small, i.e., the flushing time of the flushing device of the present application for a single vehicle is short, and the efficiency is high.
