DETAILED DESCRIPTION

[0029] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings and specific implementation methods. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0030] In the description of the present invention, it should be understood that the terms "center, lateral, longitudinal, up, down, front, back, left, right, vertical, horizontal, top, bottom, inside, outside" and the like indicate directions or positional relationships based on the attached Figure 1 The orientation or positional relationship shown is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] The present invention provides a brush head clamping mechanism, the structural schematic diagram of which is shown in FIG. Figure 1 As shown, it includes a fixing rod 3 connected to the mounting frame 1 through a first rotating structure 2, the end of the fixing rod 3 is connected to a mounting plate 4, a first clamping plate 5 and a second clamping plate 6 are symmetrically provided on both sides of the mounting plate 4, the first clamping plate 5 and the second clamping plate 6 are respectively connected to the mounting plate 4 through a second rotating structure 7, the first clamping plate 5 and the second clamping plate 6 are correspondingly provided with arcuate edges 8, and the two corresponding arcuate edges interact with each other to clamp the brush head structure 9.

[0032] By setting the first rotating structure 2 and the second rotating structure 7 between the mounting frame 1 and the brush head structure 9, the first rotating structure 2 causes the brush head structure 9 to rotate 90 degrees as a whole, so that the brush head structure 9 is close to the side of the mounting frame 1, reducing the brush head storage space; the second rotating structure 7 realizes the clamping of the brush head structure 9, reducing the space occupied by the brush head, and making the mounting frame 1 more flexible and convenient.

[0033] Two brush head clamping mechanisms can be respectively arranged on both sides of the mounting frame 1, that is, a mounting frame can be placed on each side of the car wash room to complete the work of the four vertical large brushes of the mounting frame 1. The first rotating structure (2) includes a rotating shaft 201 connecting the mounting frame 1 and the fixed rod 3, a micro-motion block 202 is arranged on the top of the rotating shaft 201, and a micro-motion sensor 203 corresponding to the position of the micro-motion block 202 is arranged on the mounting frame 1; and a motion track arc 204 is also arranged between the mounting frame 1 and the fixed rod 3.

[0034] When the brush head is needed, the fixed rod 3 moves toward the front of the mounting frame 1 along the motion trajectory arc 204. When it is perpendicular to the mounting frame 1, the micro-motion block 202 contacts the micro-motion sensor 203, and the fixed rod 3 is automatically positioned. The micro-motion block 202 is relatively fixed to the rotation axis 201, and its structure can be arc-shaped, concave, etc. The micro-motion sensor 203 can be selected from the brand: Delixi model: LXW5-11G2 micro-motion sensor. When the brush head is not used, the fixed rod 3 moves toward the side of the mounting frame 1 along the motion trajectory arc 204. When it moves to the side of the mounting frame 1, the micro-motion block 202 contacts the micro-motion sensor 203, and the fixed rod 3 is automatically positioned, which utilizes the space on the side and does not affect the space of the car wash room and the passability of the car.

[0035] The horizontal area of ​​each brush structure 9 is 0.5 square meters, and the area occupied by four brushes is 1 square meter, which greatly reduces the space required when the brush head is retracted.

[0036] The first rotating structure 2 preferably adopts this structural mode, which is convenient for production, simple for operation, and can be positioned accordingly as required.

[0037] Since the brush head has a diameter of about 70 cm and a very irregular shape, a clamping portion needs to be provided on the brush, and the brush head structure 9 includes a brush head end 901 and a clamping end 902, and a clamping hoop 903 is provided on the upper end of the clamping end 902. The two corresponding arc-shaped edges 8 of the first clamping plate 5 and the second clamping plate 6 interact with each other to clamp the brush head structure 9, that is, the clamping portion is the clamping hoop 903.

[0038] The schematic diagram of the AA section structure of the clamping part is as follows Figure 4As shown, the second rotating structure 7 includes a rotating shaft 701, one end of which is movably connected to the first clamping plate 5 or the second clamping plate 6, and a bearing 702 is provided on the outer periphery of the rotating shaft 701, and the bearing seat of the bearing 702 is connected to the mounting plate 4. The rotating shaft 701 is a stepped shaft, and the diameter of the rotating shaft 701 in contact with the first clamping plate 5 or the second clamping plate 6 may be the largest, and the clamping plate is connected to the rotating shaft 701 by a countersunk screw.

[0039] A flat washer is sleeved on the bottom end of the rotating shaft 701, and then connected by a nut, so that the rotating shaft 701 and the bearing 702 are fixed in position, and then the bearing seat of the bearing 702 is connected to the mounting plate 4, so that the upper and lower ends of the second rotating structure 7 are respectively movably connected to the first clamping plate 5 or the second clamping plate 6 and the mounting plate 4. Then the first clamping plate 5 or the second clamping plate 6 can perform relative rotational movement with the mounting plate 4 through the second rotating structure 7, and the two clamping plates are correspondingly provided with arcuate edges 8, and the two corresponding arcuate edges 8 interact with each other to clamp the brush head structure 9.

[0040] The structural diagram of the clamping part is as follows Figure 2 As shown, its side view structure schematic diagram is as follows Figure 3 As shown, in order to make the two clamping plates tightly clamp the brush head structure 9, hanging columns 10 are respectively provided on the first clamping plate 5 and the second clamping plate 6, and a spring 11 is provided between the two hanging columns 10. Under the action of the spring 11, the brush head structure 9 is clamped more stably.

[0041] When the brush head structure 9 is not clamped, due to the setting of the spring 11, the distance between the two clamping plates is reduced under the action of the elastic force. In order to prevent the two clamping plates from being too close and not being easy to clamp the brush head structure 9 again, a positioning groove 12 is provided at the other end of the first clamping plate 5 and the second clamping plate 6 that clamp the brush head structure 9, and a positioning rod 13 is provided at the corresponding position of the positioning groove 12 on the mounting plate 4. The setting of the positioning rod 13 enables the two clamping plates to maintain a certain distance when the brush head structure 9 is not clamped, so that the two clamping plates can better clamp the brush head structure 9 again.

[0042] When the clamping action is performed, the contact between the positioning rod 13 and the positioning groove 12 will generate noise, so a buffer sleeve 14 is provided at the contact point between the positioning rod 13 and the positioning groove 12 to reduce or avoid the noise. The material of the buffer sleeve 14 is preferably a nylon sleeve, which is non-slip and wear-resistant, thereby increasing its service life.

[0043] In order to enable the brush head structure 9 to be smoothly clamped into the arcuate edges 8 corresponding to the two clamping plates, the inner side of the end of the arcuate edge 8 is chamfered, and a roller 15 is set at the chamfer of the arcuate edge 8 of any clamping plate, or a roller 15 is set on the arcuate edges 8 of both clamping plates.

[0044] Working process: When the brush head structure 9 needs to be clamped for work, first, the fixed rod 3 moves from the side of the mounting frame 1 to the front along the motion trajectory arc 204. Under the action of the micro-motion block 202 and the micro-motion sensor 203, the fixed rod 3 is perpendicular to the mounting frame 1, so that the clamping mechanism on the fixed rod 3 is in a ready-to-work state; secondly, the clamping hoop 903 of the brush head structure 9 is aligned with the symmetrical center line of the first clamping plate 5 and the second clamping plate 6, and the brush head structure 9 is close to the two clamping plates. Under the action of a certain thrust, the brush head structure 9 is chamfered along the two arc-shaped edges 8 and the roller 15, so that the brush head structure 9 slides smoothly into the arc-shaped edges 8 corresponding to the two clamping plates. In the process of the brush head structure 9 entering the arc-shaped edge 8, the second rotating structure 7 rotates under the action of the bearing 701, so that the two clamping plates rotate and open. When the brush head structure 9 slides into the arc-shaped edge 8, under the action of the spring 11, the brush head structure 9 is clamped stably and safely.

[0045] When the brush head structure 9 needs to be removed or replaced, the clamping end 902 of the brush head structure 9 slides outward along the arc-shaped edge 8 under the action of external force. In the process of the brush head structure 9 sliding out of the arc-shaped edge 8, the second rotating structure 7 rotates under the action of the bearing 701, so that the two clamping plates rotate and open, and the spring 11 is stretched. After the brush head structure 9 slides out of the arc-shaped edge 8, under the action of the positioning rod 12, the first clamping plate 5 and the second clamping plate 6 maintain a certain distance, preparing for the brush head structure 9 to be clamped again.

[0046] Finally, when the work is completed, the brush head structure 9 needs to be stored. The fixed rod 3 moves along the motion trajectory arc 204 under the action of external force. Under the action of the micro-motion block 202 and the micro-motion sensor 203, the brush head structure 9 stays on the side of the mounting frame 1, reducing the brush head storage space.

[0047] To summarize, in order to solve the problem mentioned in the prior art that the brush occupies a large space, seriously affecting the space of the car washing equipment; the present invention sets a first rotating structure and a second rotating structure between the mounting frame and the brush head structure. The first rotating structure rotates the brush head structure as a whole 90 degrees, so that the brush head structure is close to the side of the mounting frame, reducing the storage space of the brush head. The coordinated use of the second rotating structure and the spring realizes the clamping of the brush head structure, reduces the space occupied by the brush head, and makes the mounting frame more flexible and convenient.
