Description

Technical Field

[0001] The present invention relates to the technical field of automobile parts, and in particular to a front-view camera windshield cleaning wiper and method. Background Art

[0002] Vehicles are usually equipped with boneless wipers, which can clear most of the rain, but it is difficult to effectively deal with flying insect residues, colloidal substances, etc. These residues will block or contaminate the front-view camera, resulting in reduced recognition effect or even failure to start working. Specific reasons include: (1) The wiping range of the wiper is not accurate: boneless wipers usually wipe the entire front windshield indiscriminately, without enhanced cleaning of specific areas of the front-view camera. (2) Insufficient cleaning ability: Traditional wiper materials have limited cleaning effect on colloidal substances and flying insect residues. Therefore, the driver needs to find a service area or make an emergency stop while driving at high speed and manually wipe the front-view camera to maintain the cleanliness of the camera.

[0003] In order to clean the front camera field of view, there are some improvement schemes in the prior art. For example, Chinese invention patent CN113787987A discloses a self-cleaning method and system for the front camera field of view of the windshield. When there are foreign objects in the field of view of the front camera, the foreign objects are cleaned by the wiper system and the washing system. The washing system controls the water spray height by adjusting the water spray nozzle angle to clean the foreign objects. Although the above scheme can clean foreign objects in the field of view of the front camera to a certain extent, it only uses the method of spraying water combined with wipers, and the treatment effect of foreign objects such as shellac is not good. Summary of the invention

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide a front-view camera cleaning wiper and method, which can achieve thorough cleaning of the front-view camera area by adding an enhanced cleaning component to ensure the normal operation of the front-view camera.

[0005] In order to achieve the above object, the present invention is implemented through the following technical solutions:

[0006] In a first aspect, an embodiment of the present invention provides a front-view camera cleaning wiper, comprising a wiper top cover, a cleaning nozzle is mounted on the wiper top cover, and enhanced cleaning components are symmetrically mounted on both sides of the cleaning nozzle;

[0007] Among them, the enhanced cleaning component includes a wiper bar, a cleaning sponge bar and a brush arranged in sequence from the outside to the inside. The wiper bar, the cleaning sponge bar and the brush are used to sequentially clean the front camera area after the cleaning nozzle sprays water.

[0008] As a further implementation, the cleaning sponge strip forms an arc-shaped groove on the side facing the cleaning nozzle installation side.

[0009] As a further implementation, the working surface of the cleaning sponge strip protrudes from the working surface of the wiper strip.

[0010] As a further implementation, the brush is detachably connected to the wiper top cover.

[0011] As a further implementation, the brush is installed at a set tilt angle.

[0012] In a second aspect, an embodiment of the present invention further provides a working method for cleaning a windshield wiper of a front-view camera, comprising:

[0013] The cleaning nozzle sprays water onto the scraping area;

[0014] The wiper moves upward, and the wiper strip, cleaning sponge strip and brush on the first side of the cleaning nozzle clean the front camera area in turn; then the brush, cleaning sponge strip and wiper strip on the second side of the cleaning nozzle continue to clean the front camera area;

[0015] The wiper moves downward, and the wiper strip, cleaning sponge strip and brush on the second side of the cleaning nozzle clean the front camera area in turn; then the brush, cleaning sponge strip and wiper strip on the first side of the cleaning nozzle continue to clean the front camera area.

[0016] As a further implementation method, during the wiping process, the wiper obtains the wiper angle through an angle sensor built into the wiper motor, and when the wiper moves upward to a set angle, the cleaning nozzle is started.

[0017] As a further implementation, during the upward movement of the wiper, the wiper strip on the first side scrapes off large particles in the shellac, the cleaning sponge strip wipes the shellac, and the brush scrapes off the residue;

[0018] Then the brush on the second side directly scrapes the shellac, the cleaning sponge strip cleans and removes the damaged shellac, and the scraper strip continues to scrape the shellac residue.

[0019] As a further implementation, during the downward movement of the wiper, the wiper strip on the second side continues to scrape the shellac residue, the cleaning sponge strip wipes the residual shellac, and the brush scrapes the residue;

[0020] The brush on the first side then scrapes the shellac directly, the cleaning sponge strip scrapes the residue into its groove, and the scraping strip removes the residue in the scraping area.

[0021] As a further implementation, the wiper up movement and the wiper down movement constitute a working cycle, and the working cycle can be repeated multiple times.

[0022] The beneficial effects of the present invention are as follows:

[0023] (1) The present invention comprises a wiper strip, a cleaning sponge strip and a brush to form an enhanced cleaning component, and the enhanced cleaning components are arranged on both sides of the cleaning nozzle. Under the sequential scraping and brushing action of the wiper strip, the cleaning sponge strip and the brush in various ways, the front camera area can be effectively cleaned; the cleaning wiper structure can be applied to the entire wiper range to achieve effective scraping of glue, etc. on the glass within the field of view.

[0024] (2) During the upward movement of the wiper of the present invention, the first wiper strip, the first cleaning sponge strip, the first brush, the second brush, the second cleaning sponge strip and the second wiper strip perform cleaning work in sequence; during the downward movement, the second wiper strip, the second cleaning sponge strip, the second brush, the first brush, the first cleaning sponge strip and the first wiper strip perform cleaning work in sequence; the upward movement and the downward movement constitute a working cycle, which can basically remove the residual shellac; for the situation where it cannot be completely removed, the working cycle can be increased.

[0025] (3) The cleaning sponge strip of the present invention has a groove curved inwardly, which can scrape the shellac and gather the scraped foreign matter to one side, which is convenient for subsequent cleaning operations; at the same time, the brush is installed at a certain angle, and the two brushes can change angles to destroy the plane structure of the shellac, thereby ensuring thorough cleaning.

DETAILED DESCRIPTION

[0030] It should be noted that the following detailed descriptions are illustrative and intended to provide further explanation of the present invention. Unless otherwise specified, all technical and scientific terms used in the present invention have the same meanings as those commonly understood by those skilled in the art to which the present invention belongs.

[0031] Embodiment 1:

[0032] Since traditional boneless wipers wipe the front windshield indiscriminately, residual colloidal substances such as flying insects will affect the recognition effect of the front camera; although there are some improvement schemes in the prior art, they cannot completely remove the residual colloidal substances. Based on this, this embodiment provides a front camera cleaning wiper, and adds an enhanced cleaning component at the wiper top cover to achieve effective cleaning and processing of the front camera area.

[0033] like Figure 1 and Figure 2 As shown, a cleaning nozzle 12 is installed in the middle position of the wiper top cover 1, and enhanced cleaning components are symmetrically installed on both sides of the cleaning nozzle 12; for the convenience of description, according to the actual running direction of the wiper, the front side of the wiper is the first side, and the rear side of the wiper is the second side, then the first side of the cleaning nozzle 12 is installed with a first enhanced cleaning component, and the second side of the cleaning nozzle 12 is installed with a second enhanced cleaning component.

[0034] Specifically, the first enhanced cleaning assembly includes a first wiper strip 4, a first cleaning sponge strip 5 and a first brush 8. Figure 1 In the direction shown, the first wiper strip 4, the first cleaning sponge strip 5 and the first brush 8 are arranged in sequence from the outer side to the inner side of the wiper top cover 1; the second enhanced cleaning component includes the second wiper strip 2, the second cleaning sponge strip 6 and the second brush 7, and the second wiper strip 2, the second cleaning sponge strip 6 and the second brush 7 are arranged in sequence from the outer side to the inner side of the wiper top cover 1.

[0035] The wiper strip is the first step in cleaning the shellac, and it extends a certain length along the length direction of the wiper top cover 1; the cleaning sponge strip is the second step in cleaning the shellac, and it can wipe the shellac after being soaked in water; and then it is scraped off by a brush.

[0036] Since enhanced cleaning components are provided on both sides of the cleaning nozzle 12 of the present embodiment, the components of the enhanced cleaning components work sequentially. During the upward movement of the wiper, the first wiper strip 4, the first cleaning sponge strip 5, the first brush 8, the second brush 7, the second cleaning sponge strip 6 and the second wiper strip 2 perform cleaning work in sequence; during the downward movement of the wiper, the second wiper strip 2, the second cleaning sponge strip 6, the second brush 7, the first brush 8, the first cleaning sponge strip 5 and the first wiper strip 4 perform cleaning work in sequence. Through the cooperation of the above-mentioned structures, the front-view camera area 10 can be thoroughly cleaned.

[0037] In this embodiment, the wiper strip can be made of materials such as silicone and rubber, and can scrape large particles of shellac. In order to achieve effective scraping, the cross section of the wiper strip is set to be triangular to form a linear working surface at the end of the wiper strip (the end away from the wiper top cover 1).

[0038] The cleaning sponge strip is made of sponge material and can wipe the front windshield after absorbing water. The cleaning sponge strip is connected to the wiper top cover 1 through a support plate. The end of the cleaning sponge strip exceeds the working surface of the wiper strip by a certain distance, that is, the working surface of the cleaning sponge strip protrudes from the working surface of the wiper strip, so that the cleaning sponge strip after absorbing water can effectively contact the front windshield, producing a squeezing and wiping effect. In order to enable the cleaning sponge strip to further remove the shellac and form a certain aggregation effect, the cross section of the cleaning sponge strip is set to an arc structure, and the inner side (towards the installation side of the cleaning nozzle 12) forms an arc-shaped groove.

[0039] The brush is installed on the inner side of the cleaning sponge strip, and the brush in this embodiment is a nylon brush. The first brush 8 and the second brush 7 are at a certain angle to the center line direction of the cleaning nozzle 12, so that a certain angle is formed between the first brush 8 and the second brush 7, so that the scraping direction can be changed by the first brush 8 and the second brush 7, and the scraping effect can be further ensured.

[0040] The brush of the present embodiment is detachable, and it can be plugged into the replacement slot 3 provided with the wiper top cover 1. Of course, the wiper strip and the cleaning sponge strip can also be arranged as a detachable structure to ensure that each component can work normally and ensure the cleaning effect.

[0041] The wiper of this embodiment can adjust the size of the enhanced cleaning component so that it can be applied to the entire wiper range, thereby effectively scraping shellac and the like on the glass within the field of view.

[0042] Embodiment 2:

[0043] The present embodiment provides a working method for cleaning wipers with a front-view camera, using the wipers described in Embodiment 1. When the vehicle is traveling at high speed, if the field of view of the front-view camera is obstructed due to factors such as insect impact, thereby affecting the normal activation of the adaptive cruise function, the system will automatically activate the wiper water spray cleaning mode, and the wiper will drive the enhanced cleaning component at its front end to perform a wiping operation on the wiping area 11 of the front windshield.

[0044] The specific process is:

[0045] During the wiping process, the angle sensor built into the wiper motor can collect the upward angle of the wiper in real time. When the wiper blade 9 rises to a certain angle, such as 45°, the wiper cleaning water pump is turned on to control the cleaning nozzle 12 to spray water. First, the first wiper strip 4 first contacts the shellac and performs preliminary scraping of large particles. Then, the first cleaning sponge strip 5 soaked in water will wipe the shellac. Since the first cleaning sponge strip 5 has an arc-shaped groove formed on the inner side, it can remove the damaged shellac when it moves upward, forming a pre-cleaning for the second cleaning sponge strip 6 before work.

[0046] Then, the first brush 8 sweeps the residue with its brush head, the wiper continues to move upward, and the brush head of the second brush 7 directly scrapes the shellac, which can destroy the overall residual plane structure of the shellac. After that, the second cleaning sponge strip 6 cleans and removes the damaged shellac, and the second wiper strip 2 continues to scrape the shellac residue.

[0047] During the upward movement, the first wiper strip 4, the first cleaning sponge strip 5, the first brush 8, the second brush 7, the second cleaning sponge strip 6 and the second wiper strip 2 perform corresponding scraping and brushing operations in sequence, so that the shellac can be partially removed during the upward movement.

[0048] In order to completely remove the shellac, the wiper continues the downward process; when starting to go down, the second wiper strip 2 first scrapes the destroyed shellac residue again, and the second cleaning sponge strip 6 further wipes the residual shellac on the windshield. Then, the second brush 7 sweeps the residue again during the downward process, and the first brush 8 directly scrapes the shellac with the brush head to further destroy the plane structure of the shellac. Finally, the first cleaning sponge strip 5 scrapes the residue on the windshield into the groove, and then the first wiper strip 4 scrapes the residue, completing the thorough cleaning of the entire scraping area 11.

[0049] Normally, the residual shellac can be basically removed after one working cycle, but in cases where there is a lot of shellac or it is firmly attached, multiple working cycles can be repeated to ensure that the front camera area 10 is thoroughly cleaned.

[0050] The above description is only the preferred embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
