Description

Technical Field

[0001] The present invention relates to the technical field of automotive accessories, and particularly to windshield wipers. Background Art

[0002] The main function of a windshield wiper is to sweep away rain, snow and dust on the windshield that obstruct the view. During actual use, the water tank pump directly sprays windshield washer fluid onto the windshield, and then the wiper operates to clean the windshield. However, the shape, angle and coverage area of the sprayed windshield washer fluid all have a direct impact on the wiping effect.

[0003] In an existing windshield wiper, the cleaning liquid flows from the liquid supply pipe at the installation end through the liquid inlet channel to the working end and sprays out from the nozzle holes at the working end, so that the cleaning liquid is evenly sprayed on the places where the wiper blade passes. At the same time, the elastic pressing member always elastically supports the rubber strip, enabling it to better fit the glass, and making the cleaning and dust removal effects remarkable. The heat conducting plate in contact with the rubber strip heats up the rubber strip, which can remove the frost and ice on the glass. The rubber strip is fixed to the skeleton by the clip arm. When the rubber strip needs to be replaced, it can be simply removed from the clip arm, which is convenient for replacement and can accommodate rubber strips of different models, with strong versatility.

[0004] However, the traditional windshield wiper consists of a strip-shaped skeleton and a rubber strip, completely relying on the traditional skeleton structure, resulting in a low degree of fit between the windshield wiper and the front windshield glass, thus affecting the cleaning effect. At the same time, the windshield wiper uses an independent liquid supply pipeline, and the distance between the liquid supply pipeline and the nozzle is relatively long, resulting in possible interruption of the flow of the sprayed cleaning liquid, with poor continuity. Moreover, the heat conducting plate used can only heat the rubber strip, and the temperature of the independent liquid supply pipeline is relatively low due to cold weather, having limited ability to melt the frost or snow on the front windshield glass and unable to quickly remove it, with a general cleaning effect.

[0005] Therefore, there is an urgent need for a windshield wiper to solve the above problems. Summary of the Invention

[0006] The purpose of the present invention is to provide a windshield wiper, which while reducing weight, increases the degree of fit with the front windshield glass, and at the same time, achieves continuous linear spraying, and can quickly melt the frost or snow on the front windshield, thus ensuring clear vision in cold weather.

[0037] As Figures 1-4 shown, in this embodiment, the wiper includes a boneless wiper blade 1, an elastic member 2, a heating member 3, and a nozzle 4. Among them, a water flow channel 11 is provided inside the boneless wiper blade 1. The water flow channel 11 has a water inlet end and a water outlet end. The water inlet end of the water flow channel 11 is communicated with the water tank through a water pipe and extends along the length direction of the boneless wiper blade 1. The elastic member 2 is arranged inside the boneless wiper blade 1 and is located beside the water flow channel 11. The heating member 3 is integrally arranged on the elastic member 2 and is electrically connected to the vehicle circuit. The heating member 3 is used to heat the liquid in the boneless wiper blade 1 and the water flow channel 11. The nozzle 4 is integrally arranged on the boneless wiper blade 1 and is communicated with the water outlet end of the water flow channel 11.

[0038] The boneless wiper blade 1 is designed to be a boneless structure, which reduces the weight while increasing the fitting degree with the front windshield glass, thus improving the cleaning efficiency. The boneless wiper blade 1 is internally provided with a water flow channel 11. This embedded design can increase the number of nozzles 4 and shorten the distance between the nozzles 4 and the water flow channel 11, realizing true continuous linear spraying. The water flow channel 11 is connected to the water pipe of the water tank, and the cleaning liquid in the water tank fills the water flow channel 11 through the vehicle-mounted system to ensure sufficient supply of the cleaning liquid. The nozzles 4 are integrally arranged on the boneless wiper blade 1. The nozzles 4 spray the cleaning liquid in the water flow channel 11 onto the front windshield glass. During the process of the wiper blade wiping the front windshield glass, the windshield washer fluid or cleaning liquid can be directly and evenly sprayed through the nozzles 4 in front of the sliding direction of the wiper, laying a "water channel" for the wiper in advance. The spraying coverage area is large, reducing the dry grinding area at the moment when the wiper blade starts, reducing noise and glass wear, effectively extending the service life of the wiper blade, and having a better cleaning effect.

[0039] The elastic member 2 is set as a reed, and the heating member 3 is set as a heating foil. The elastic member 2 simultaneously bears the heating function. Compared with the traditional externally hung heating water pipe, the integrated setting of the heating member 3 on the elastic member 2 shortens the heating response time. The elastic member 2 and the heating member 3 are arranged in the inner cavity of the boneless wiper blade 1. The elastic member 2 can make the end face of the boneless wiper blade 1 closely fit with the front windshield glass, and the cleaning effect is good. The heating member 3 is distributed with resistance wires, and the heating member 3 is electrically connected to the motor of the wiper through a control circuit board. When the wiper operates, the motor sends a high level to the control circuit board, and the control circuit board can control the heating member 3 to turn on and heat. The heating member 3 can heat the boneless wiper blade 1 and the water flow channel 11 simultaneously, with a good heating effect, and can quickly melt the ice, frost or snow on the front windshield glass, thus ensuring clear vision in cold weather.

[0040] Refer to Figures 2-4 , the boneless wiper blade 1 includes a sheath 12 and a wiper blade 13. The wiper blade 13 is provided with a plug-in groove, and the sheath 12 is provided with a plug-in member. The plug-in member can be inserted into the plug-in groove to fix the wiper blade 13 on the sheath 12. The inner circumference of the sheath 12 is convexly provided with a plug-in member, and the wiper blade 13 is provided with a plug-in groove corresponding to the plug-in member. The sheath 12 and the wiper blade 13 are fixedly connected to each other through the plug-in and plug-in groove cooperation, with firm installation and not easy to loosen. And, the plug-in member can be inserted and pulled out relative to the plug-in groove under the action of an external force, so that the wiper blade 13 can be detached from the sheath 12, which is convenient for disassembly and replacement.

[0041] Continue to refer to Figures 2-4, the sheath 12 includes a main body portion 121 and a clamping portion 122. The main body portion 121 has a clamping groove 1211, and the clamping portion 122 is clamped within the clamping groove 1211. An accommodating groove 1221 is provided on the inner side of the clamping portion 122, and the accommodating groove 1221 is configured to accommodate the elastic member 2 and the heating member 3. The main body portion 121 surrounds the outer periphery of the clamping portion 122 through the clamping groove 1211. The main body portion 121 is provided with a protrusion 1212, and a groove 1222 is formed on the outer side of the clamping portion 122. The protrusion 1212 is clamped within the groove 1222, ensuring firm fixation. The clamping portion 122 surrounds the outer peripheries of the elastic member 2 and the heating member 3 through the accommodating groove 1221, and they are integrally arranged in a nested manner, with a compact structure. At the same time, the heating member 3 can heat the boneless wiper 1 and the water flow channel 11 simultaneously, with a good heating effect, capable of quickly melting the ice, frost, or snow on the front windshield, thereby ensuring clear vision in cold weather.

[0042] Preferably, the plug-in member includes two plug-in portions, which are opposite and spaced apart on the inner walls of both sides of the sheath 12. Through the cooperation of the two plug-in portions and the two plug-in grooves of the corresponding wiper blade 13, the wiper blade 13 can be further fixed to the sheath 12, preventing the wiper blade 13 from falling off during the reciprocating movement of the wiper on the front windshield and affecting the cleaning effect of the wiper. Optionally, the number of plug-in members and plug-in grooves are both provided with multiple. Along the length direction of the boneless wiper 1, the multiple plug-in members are spaced apart, and the multiple plug-in members are respectively plugged into the plug-in grooves one by one, making the connection between the wiper blade 13 and the sheath 12 more stable and not easily loosening.

[0043] Referring to Figure 2 and Figure 4 , the wiper blade 13 includes a limiting portion 131, a wiper portion 132, and a connecting portion 133. The longitudinal section of the wiper portion 132 is in an inverted triangular structure. The limiting portion 131 is provided with multiple plug-in grooves, which are spaced apart along the height direction of the limiting portion 131, ensuring the stable connection between the wiper blade 13 and the sheath 12 along the vertical height direction and preventing the wiper blade 13 from detaching from the sheath 12 along the height direction of the wiper blade 13. The two ends of the connecting portion 133 are respectively flexibly connected to the limiting portion 131 and the wiper portion 132. The limiting portion 131 functions to fix the wiper blade 13. The flexibility of the connecting portion 133 is greater than that of the limiting portion 131 and the wiper portion 132. During the reciprocating movement of the wiper on the front windshield, the wiper portion 132 slides and fits with the windshield. Under the action of the connecting portion 133, it can ensure a good cleaning effect of the wiper portion 132 and is not easily broken, extending the service life.

[0044] Referring to Figures 1-2, the nozzle 4 is provided with a plurality of spray holes, and the plurality of spray holes are arranged in a matrix. The nozzle 4 is set as an atomizing nozzle 4 to ensure that the washing liquid is evenly distributed in front of the sliding direction of the boneless wiper 1 in the form of fine mist through the nozzle 4, fully lubricate the glass, and improve the wiper effect on the windshield. Moreover, the water spraying landing points are more than those of the traditional ones, the water spraying area is large, and the coverage range is wide, avoiding the noise and damage caused by dry scraping.

[0045] Obviously, the above-mentioned embodiments of the present invention are only examples for clearly illustrating the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the present invention. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the claims of the present invention.
