Description

A three-dimensional car wash brush

technical field

The invention relates to the technical field of automobile cleaning appliances, and more particularly, to a three-dimensional car washing brush.

Background technique

When we use the vehicle for a period of time, due to dust, mud, oil and other reasons, after the surface of the vehicle is covered with a layer of dirt, we need to clean the surface of the vehicle regularly to keep the surface of the vehicle clean.

For this reason, automatic car washing machines are gradually replacing manual car washing in various cities due to their advantages of high efficiency, cleanliness, and labor cost saving. During the cleaning process of the car washing machine, the two sides of the car body are generally cleaned through the vertical vertical brush assembly. The vertical brush assembly is the car wash brush.

When it is necessary to clean the up, down, left, and right directions of the car, at least lateral guide rails and longitudinal guide rails need to be provided to drive the car wash brush to clean up, down, left, and right, which is complicated in structure and high in cost.

technical problem

The purpose of the present invention is to provide a three-dimensional car washing brush, which has a simple structure and can perform cleaning in four directions, up, down, left, and right, without installing lateral guide rails or longitudinal guide rails at the same time.

technical solutions

In order to achieve the above purpose, it is achieved by the following technical means: a three-dimensional car washing brush, characterized in that it includes a brush roller and a brush body, an iron ring is coaxially sleeved and fixed on the upper part of the brush roller, and the iron ring is vertically below. N springs and ring electromagnets are arranged alternately. Both the springs and electromagnets are sleeved on the brush roller, but not fixed with the brush roller. The top end of the first spring is fixed on the iron ring, and the bottom end is connected to the first electromagnet. The top end is fixed, the top end of the second spring is fixed with the bottom end of the first electromagnet, the bottom end is fixed with the top end of the second electromagnet, and so on, until the bottom end of the Nth spring is fixed with the Nth electromagnet The bottom end is fixed, and each electromagnet and the outer circumferential surface of the iron ring are arranged with brush bodies extending outward.

Through the above technical solution, when the three-dimensional car washing brush is installed on the automatic car washing machine, so that the brush roller can be rotated, the spring sleeved on the brush roller will also be thrown out under the action of centrifugal force, and due to the spring The action of its own restoring force will go up again, thereby driving the brush body on the magnet to move up and down, that is, to achieve the effect of horizontal cleaning of the body and to achieve the effect of cleaning up and down, and realize the three-dimensional cleaning of the body. In this way, only one lateral guide rail needs to be installed so that the car washing brush can walk laterally to realize the cleaning in four directions of up, down, left and right.

Further optimization is: each annular electromagnet is controlled by a magnetron circuit, and the magnetron circuit includes electromagnets connected in series with each other, a remote control switch controlled by a remote controller, a consumption resistor and a power supply for maintaining circuit consumption , each electromagnet has an attractive relationship with the adjacent electromagnet after it is energized.

Through the above technical solution, each ring electromagnet is controlled by a magnetic control circuit to realize the real function of the electromagnet (that is, it has a magnetic function). In this way, the electromagnet can be controlled by controlling the remote control. Throw it out and go down. When it goes too far down and it is difficult to take it back, you can control one or several electromagnets to get electricity, so that the electromagnet below will be adsorbed, and the brush body will move upwards. Then, the electricity of the electromagnet is disconnected, and the spring and electromagnet are thrown out and moved downward, so that the up and down movement can be realized over and over again. Combined with the lateral walking of the car brush, the car can be cleaned in four directions, up and down, left and right.

A further optimization is as follows: the brush roller is vertically provided with outwardly convex guiding ribs, and each electromagnet is concavely provided with a notch matched with the guiding ribs.

Through the above technical solution, the guide edge on the brush roller and the notch on the electromagnet can be matched together, so that when the electromagnet is thrown out, it can only move along the guide edge, instead of being twisted randomly with the spring, the electromagnet is limited If it is in place, it will also limit the torsion of the spring, so that the brush body will not be twisted and tangled.

Further optimization is: two guide edges are vertically arranged on the brush roller.

Through the above technical solution, the arrangement of the two guide edges can better serve to limit the up and down movement trajectory of the electromagnet.

A further optimization is: the two guide edges are arranged opposite to each other on the brush roller.

Through the above technical solution, the two guide edges arranged oppositely are equivalent to the two notches on the electromagnet are also arranged oppositely, so that the relative guide design makes the electromagnet guided in a left-right balance, so that the up and down movement of the electromagnet is more stable .

It is further optimized that the two guide edges both extend from the upper end of the brush roller to the lower end.

Through the above technical solution, the guide rib is designed to extend from the upper end of the brush roller, not from the top, so as to facilitate the fixed installation of the top of the brush roller on the automatic car washing machine, and make it extend to the bottom end, in order to avoid the spring and the The electromagnets are thrown away from the brush rolls so that they are guided by guide ribs throughout their downward movement.

A further optimization is: the power supply is a rechargeable battery.

Through the above technical solution, the power supply is set to the battery, the battery is small in size, does not occupy an area, and is easy to store, and the battery is rechargeable. energy.

On the outer circumference of the ring and the electromagnet, then driven by different rotational speeds, the brush roller rotates, so that the spring and the electromagnet move up and down under the action of centrifugal force and spring restoring force, so as to achieve lateral cleaning of the body at the same time. The effect of up and down cleaning is achieved, and the three-dimensional cleaning of the body is realized; the design of the guiding edge and the gap makes the electromagnet not twist with the spring when moving up and down, and the moving route follows the guiding edge, which is more convenient to move.

BEST MODE FOR CARRYING OUT THE INVENTION

The invention will be described in further detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive, not limiting the protection scope of the present invention.

Example

As shown in Figure 1, a three-dimensional car washing brush includes a brush roller and a brush body. The brush roller is a vertical circular roller. The upper part of the brush roller is coaxially sleeved and fixed with an iron ring, and the iron ring is fixed on the brush. On the upper part of the roller, N springs and annular electromagnets are arranged alternately vertically below the iron ring. The springs and electromagnets are both sleeved on the brush roller, but not fixed with the brush roller. The top of the first spring is fixed on the iron ring. up, the bottom end is fixed with the top end of the first electromagnet, the top end of the second spring is fixed with the bottom end of the first electromagnet, the bottom end is fixed with the top end of the second electromagnet, and so on, until the Nth The bottom end of the spring is fixed with the bottom end of the Nth electromagnet, and the value of N is greater than or equal to 3, and the specific value depends on the length of the brush roller. A brush body is arranged on the outer circumferential surface of each electromagnet and the iron ring to extend outward.

In this way, after the car washing brush is installed on the automatic car washing machine, the brush roller rotates, and the spring set on the brush roller will be thrown out under the action of centrifugal force, and will go up again due to the restoring force of the spring itself. When the spring moves up and down, it also drives the electromagnet to move up and down, thereby driving the brush body on the magnet to move up and down, that is, to achieve the effect of cleaning the body horizontally and up and down, and realize the three-dimensional cleaning of the body. In this way, only one lateral guide rail needs to be installed so that the car washing brush can walk laterally to realize the cleaning in four directions of up, down, left and right.

In order to avoid the situation of insufficient spring restoring force and insufficient upward movement of the brush body, we can control each electromagnet by a magnetron circuit, which includes electromagnets connected in series and controlled by a remote control. The remote control switch and the consumption resistance and power supply used to maintain the circuit consumption, each electromagnet is in an attractive relationship with the adjacent electromagnet after it is energized. By controlling the remote control, the electromagnet can be controlled to gain or lose power. When the spring and electromagnet are thrown out and go down, and it is too far to go back, it can control one or several electromagnets to gain power, so that the The lower electromagnet will be adsorbed, and the brush body will move upward, and then the electricity of the electromagnet will be disconnected, and the spring and electromagnet will be thrown out and move downward, so that the up and down movement can be realized again and again.

In order to avoid torsion when the spring is thrown out, we vertically set outwardly convex guiding ribs on the brush roller, and each electromagnet is concave with a notch (not shown in the figure) that matches the guiding ribs. The movement of the notch in the electromagnet along the guide edge limits the torsion of the electromagnet and spring. In order to make the guiding effect better, two guiding edges are vertically arranged on the brush roller, and the two guiding edges are oppositely arranged on the brush roller. Both of the two guide ribs extend from the upper end of the brush roller to the lower end.

More optimally, on the magnetron circuit, the power supply is a rechargeable battery. Set the power supply to battery, the battery is small in size, does not occupy a lot of space, and is easy to store. The battery is rechargeable. When the battery is out of power, just remove it and charge it, and there is no need to replace a new battery, saving energy. The remote control switch is a switch with Changxin brand model CX-Y05-02.

The car washing brush of the invention is simple in structure and convenient to use, and can realize cleaning in four directions of up, down, left, and right.

The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above-mentioned embodiments, and all technical solutions under the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those skilled in the art, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
