Description

Side brush device of car washing machine

The invention relates to a car washing machine, in particular to a side brush device of a car washing machine suitable for washing the side, front and rear of a vehicle.

A general car washing machine usually includes a car washing frame defining a car washing space, and a side brush device, a top brush device, a blowing device, a liquid spraying device and a spraying device mounted on the car washing frame and facing the car washing space Wax device, in order to allow the car wash frame to move relative to a vehicle, some car wash opportunities will be buried on the ground to guide the movement of the base frame, and some are installed on the ground to drive the vehicle slowly through the car wash For a conveyor belt in space, the side brush device basically includes a base frame, and two side brush modules that are mounted on the base frame correspondingly left and right and are rotatable.

Although the side brush module of the conventional car washing machine can scrub the left and right sides of the vehicle, and brush the front and rear of the vehicle by moving to the middle, the side brush device lacks a collision prevention mechanism. Therefore, when During the movement and rotation of the side brush modules along the set stroke, if the distance between the vehicle and the side brush modules is too close, the side brush modules may scratch or even damage the vehicle, Therefore, the safety of the conventional side brush device in use is relatively poor.

In addition, the side brush modules of the conventional side brush device move synchronously. This structure has no problem when cleaning both sides of the vehicle, but when the side brush modules move synchronously to the middle and brush the vehicle In the front or rear of the vehicle, since the brush cloths of the side brush modules expand radially during rotation, in order to avoid the collision and interference of the brush cloths that expand radially when the side brush modules abut in the middle, generally The car wash schedule is set, and the brush cloths of the side brush modules cannot exceed the center line of the car wash space when deployed, so that the brush cloth cannot wash the front and rear of the vehicle near the middle The area usually needs to be matched with manual brushing, so it will cause waste of manpower.

The structure of the brush unit 45 is not particularly limited, as long as it can be rotatably suspended under the hanging seat 413 of the hanging unit 41, in this embodiment, the brush unit 45 has a hanging hanging on the hanging The roller brush 451 under the pedestal 413 and a brush motor 452 driving the roller brush 451 to rotate. Since how the roller brush 451 rotates is not the focus of the improvement of the present invention, it will not be described in detail.

The safety detection mechanism 5 has an L-shaped mounting seat 51 combined with the pivot end 312 of the swing arm 31, the mounting seat 51 has a first assembly hole parallel to the extending direction of the first spring 432 511, and a second assembly hole 512 parallel to the extending direction of the second spring 442, and the safety detection mechanism 5 further has a first sensing unit 52 and a second sensing side unit 53. The first sensing unit 52 has a first sensing portion 521 disposed on one of the side walls 414 of the yaw base 411, and a first adjustable mounting position mounted on the first assembly hole 511 The detecting element 522, the second sensing unit 53 has a second sensing portion 531 disposed on the side wall 414 of the yaw base 411, and an adjustable mounting position mounted on the second assembly hole 512的Second detection element 532.

In this embodiment, the first detecting element 522 and the second detecting element 532 adopt a proximity switch, and the first sensing portion 521 and the second sensing portion 531 are both in the form of a gap, but when the present invention is implemented Not limited to the foregoing example, as long as the first and second detecting elements 522, 532 can correspond and stagger relative to the first and second sensing portions 521, 531, and generate a sensed signal, it is suitable Used in the present invention.

2, 3 and 6, when the side brush device 10 of this embodiment is used, as the car washing frame 13 of the car washing machine 1 moves relative to the vehicle 12, of course, the fixed car washing frame 13 may also be used. In addition, the conveyor belt not shown in the figure is used to drive the vehicle 12 to move into the car washing space 11 of the car washing machine 1. When the side brush device 10 is in a normal position shown in FIG. 6, the scrubbing mechanism 4 of each side brush module 101, 102 is held by the first spring 432 and the second spring 442 In a balanced state, at this time, the first detecting element 522 mounted on the mounting base 51 corresponds to the first sensing portion 521 on the yaw base 411, and the second detecting element 532 corresponds to the The second sensing portion 531 on the yaw base 411.

When the front of the vehicle 12 gradually passes through the base frame 2 of the side brush device 10, the driving cylinder 33 of the side brush module 101 will drive the swing arm 31 to pivot toward the center branch line 111, preferably When the brush cloth of the roller brush 451 is spread out in the radial direction, the end crosses the middle branch line 111 to wash the middle area of the vehicle head, because the side brush module 101 is in the process of washing the vehicle head, the other side brush module 102 The distance 20 is spaced from the side brush module 101 along the car washing direction 15, so the brush unit 45 of the side brush module 101 moving toward the front of the vehicle will not be connected to the other side brush module 102 The brush unit 45 interferes.

Similarly, when the side brush module 102 approaches the middle branch line 111 and brushes the head of the vehicle 12, the brush unit 45 of the other side brush module 101 already corresponds to the side of the vehicle 12, That is, the rolling scrubbing areas of the rolling brushes 451 of the side brush modules 101 and 102 will not overlap at the same time. By scrubbing the car head at different times without interfering with each other, the purpose of scrubbing the car head can be achieved Since the situation at the rear of the vehicle 12 is the same, it will not be described again.

Referring to FIGS. 3, 5, and 7, when the side brush device 10 is in use and the vehicle 12 is too close to one of the side brush modules 101, 102, the brush of the side brush modules 101, 102 The tool unit 45 and the hanging unit 41 will overcome the elastic force of the first spring 432 and the second spring 442 and deflect with the yaw support shaft 42 as a fulcrum. The first sensing part 521 and the second sensing part 531 on the swing seat 411 will also deviate from the corresponding first detecting element 522 or the second detecting element 532 due to deflection, at this time One of the first detecting element 522 and the second detecting element 532 is blocked by one of the side walls 414 of the yaw base 411, and at the same time, it is switched to an abnormal position shown in FIG.

That is, by the first detecting part 522 being staggered by the first sensing part 521, or the second detecting part 532 being staggered by the second sensing part 531, a sensing signal can be generated and the The yaw angle and direction of the brush unit 45. In the abnormal position, the aforementioned detection signal drives the driving cylinder 33 to expand and contract by the control circuit of the internal key, so that the scrubbing mechanism 4 moves away from the vehicle 12 to avoid the brush unit 45 being too close to the The vehicle 12 collides or scratches the vehicle 12.

As can be seen from the above description, in addition to the novel structure, the side brush device 10 of the present invention can also be detected by the safety detection mechanism 5 during the car washing process to prevent the brush unit 45 from being too close to the collision or scratching the Vehicle 12, and the side brush modules 101, 102 are separated by the distance 20 along the car washing direction 15 to allow the side brush modules 101, 102 to produce a time difference when washing the head and the rear of the vehicle, avoiding the side brushes The modules 101 and 102 move to the middle and interfere with each other at the same time, thereby improving the problem of the conventional side brush device cleaning the front and rear of the car, so the present invention is indeed a car washer 1 with a novel structure and industrial utilization value.侧刷装置10。 Side brush device 10.
