DETAILED DESCRIPTION

[0050] The embodiments of the present application will be described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and should not be construed as limitations on the present application. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without making creative work are within the scope of protection of the present application.

[0051] The scraper arm provided in the embodiment of the present application is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0052] It should be noted that, in the embodiment of the present application, the scraper arm includes a first direction x, a second direction y, and a third direction z that intersect each other, wherein the first direction x is the direction indicated by the arrow x in the accompanying drawings, i.e., the length direction of the scraper arm in the present application, the second direction y is the direction indicated by the arrow y in the accompanying drawings, i.e., the height direction of the scraper arm in the present application, and the third direction z is the direction indicated by the arrow z in the accompanying drawings, i.e., the width direction of the scraper arm in the present application. The embodiment of the present application does not specifically limit the angle between the first direction x, the second direction y, and the third direction z, but in actual application, the first direction x, the second direction y, and the third direction z are preferably perpendicular to each other in pairs.

[0053] Reference Figures 1 to 10 , shows a schematic diagram of the structure of the scraper arm described in the embodiment of the present application, such as Figures 1 to 10 As shown, the scraper arm disclosed in the present application may specifically include: a scraper arm body 10 and a first water spray component 20, the first water spray component 20 is connected to the scraper arm body 10; wherein the first water spray component 20 includes a first water spray port 201 and a second water spray port 202, and the first water spray port 201 and the second water spray port 202 have different directions.

[0054] Specifically, the scraper arm body 10 can be used to connect with the scraper arm seat, and connected with the driving mechanism of the vehicle windshield wiper through the scraper arm seat, so that the scraper arm can swing under the driving action of the driving mechanism. Since the first water spray port 201 and the second water spray port 202 are oriented in different directions, the first water spray member 20 can spray detergent in two different directions, further increasing the spraying area of ​​the scraper arm and helping to improve the scraping effect.

[0055] In an embodiment of the present application, the scraper arm body 10 includes a side wall and a port formed by the side wall, wherein the scraper arm body 10 includes a first end and a second end which are arranged in opposite directions, the first end of the scraper arm body 10 is connected to the scraper arm seat, the port is formed at the second end of the scraper arm body 10, a first opening is provided on the side wall, the first water spray outlet 201 sprays liquid outward through the first opening, and / or the second water spray outlet 202 sprays liquid outward through the first opening.

[0056] Specifically, the scraper arm body 10 forms a accommodating cavity at the second end, the first water spray member 20 is connected in the accommodating cavity and is arranged opposite to the first opening, so that the first water spray member 20 can spray liquid outward through the first opening. Specifically, the first water spray port 201 and the second water spray port 202 on the first water spray member 20 can spray liquid outward through the first opening.

[0057] It should be noted that the scraper arm body 10 may include three side walls and an end wall, and form a closed port at the second end, or the scraper arm body 10 may include three side walls, the three side walls enclose a U-shaped groove, and form an open port at the second end. The present application does not make any specific limitations on this.

[0058] In an embodiment of the present application, the scraper arm body 10 includes a side wall and a port formed by the side wall. One end of the scraper arm body 10 is connected to the scraper arm seat. The port is formed at the other end of the scraper arm body 10 away from the scraper arm seat. A first opening is provided on the side wall; wherein the first water spray outlet 201 extends outward through the first opening, and / or the second water spray outlet 202 extends outward through the first opening.

[0059] Specifically, the scraper arm body 10 forms a accommodating cavity at the second end, the first water spray member 20 is connected in the accommodating cavity and is arranged opposite to the first opening, so that the first water spray member 20 can spray liquid outward through the first opening. Specifically, the first water spray port 201 and the second water spray port 202 on the first water spray member 20 can extend outward through the first opening.

[0060] In the embodiment of the present application, the first water spraying port 201 and the second water spraying port 202 are flat ports.

[0061] Specifically, the first water spraying member 20 is integrated with the first nozzle and the second nozzle, and the first water spraying port 201 and the second water spraying port 202 are respectively arranged on the first nozzle and the second nozzle. The first water spraying port 201 and the second water spraying port 202 are arranged as flat ports, so that fan-shaped water spraying can be realized. Further, the first nozzle and the second nozzle are respectively rotatably connected in the first water spraying member 20, and can rotate. When the first nozzle and the second nozzle rotate, their water spraying ports also rotate accordingly, so as to realize the adjustment of the water spraying direction. It should be noted that the first nozzle and the second nozzle here rotate with the water delivery direction as the axial direction; further, the first nozzle and the second nozzle can also be configured to be able to flip within the range of 30° upward and 30° downward in the direction perpendicular to the length direction of the water spraying port, so as to further realize the adjustment of the water spraying angle and increase the water spraying range.

[0062] It can be understood that when the first nozzle and the second nozzle are rotated axially along the water delivery direction, when their flat-mouthed water spray outlets are rotated to be parallel to the windshield, they can have the largest water spraying area, and when the first nozzle and the second nozzle are flipped upward to the maximum angle, they can achieve water spraying at the longest distance.

[0063] In the embodiment of the present application, the first water spraying member 20 is detachably connected to the scraper arm body 10 .

[0064] In actual application, detergent is generally stored in a liquid storage pot of a vehicle. The liquid storage pot will produce sediment after long-term use. When the washing pump of the vehicle pumps the detergent to the scraper arm for water spraying and scraping, if the sediment in the liquid storage pot is transported to the water pipe of the scraper arm, it is easy to cause the nozzle on the water spray part to be blocked, thereby affecting the water spraying of the scraper arm. When the nozzle is blocked, the maintenance personnel need to disassemble the water spray part to repair the water spray part or replace the water spray part to ensure the water spraying effect of the scraper arm; therefore, the water spray part is set to be detachably connected to the scraper arm body 10, which is convenient for the installation and disassembly of the water spray part, enhances the convenience of connecting the water spray part with the scraper arm body 10, and can also improve the efficiency of later maintenance.

[0065] In the embodiment of the present application, the scraper arm also includes a second water spray member 30, which is arranged on the scraper arm body 10 with an interval with the first water spray member 20, wherein the second water spray member 30 includes a third water spray port 301, and the third water spray port 301 has the same direction as the first water spray port 201.

[0066] Specifically, the second water spraying member 30 is arranged between the first end and the second end of the scraper arm body 10 and is spaced apart from the first water spraying member 20 . A third water spraying port 301 is arranged on the second water spraying member 30 for spraying water, thereby increasing the spraying area of ​​the scraper arm body 10 .

[0067] In the embodiment of the present application, the scraper arm body 10 includes a side wall, and a second opening 13 is provided on the side wall; wherein the third water spray port 301 sprays liquid outward through the second opening 13 .

[0068] It should be noted that the side walls of the scraper arm body 10 enclose a receiving groove, the second water spraying member 30 is disposed in the receiving groove, and the third water spraying port 301 is opposite to the second opening 13 , so that liquid can be sprayed outward through the second opening 13 .

[0069] In the embodiment of the present application, the third water spraying port 301 is a flat port.

[0070] Specifically, a third nozzle is integrated in the second water spraying member 30, and a third water spraying port 301 is arranged on the third nozzle. The third water spraying port 301 is arranged as a flat port to realize fan-shaped water spraying. It should be noted that the structure of the third nozzle is similar to that of the first nozzle and the second nozzle, and the connection and water spraying method of the third nozzle can refer to the second nozzle, which will not be repeated here.

[0071] Optionally, there are multiple second water spray members 30 , and the multiple second water spray members 30 are arranged on the scraper arm body 10 at intervals along the first direction x.

[0072] Specifically, the scraper arm body 10 may be provided with a plurality of second openings 13 along the first direction x, and the plurality of second openings 13 are arranged at intervals. In practical applications, one second water spraying member 30 is connected to one second opening 13, and the plurality of second water spraying members 30 may be arranged at intervals on the scraper arm body 10. It can be understood that since the plurality of second openings 13 are arranged at intervals along the length direction of the scraper arm body 10, when the plurality of second openings 13 are arranged at intervals on the scraper arm body 10, the water spraying range of the scraper arm may be larger. In addition, the plurality of second openings 13 may be arranged at even intervals, so as to achieve a more even water spraying effect, which is conducive to enhancing the scraping and brushing effect of the scraper arm and improving the scraping cleanliness.

[0073] In the embodiment of the present application, the second water spraying member 30 is detachably connected to the scraper arm body 10 .

[0074] Similar to the first water spray component 20 being detachably connected to the scraper arm body 10, the second water spray component 30 is configured to be detachably connected to the scraper arm body 10, which also facilitates the installation and disassembly of the second water spray component 30, enhances the convenience of connecting the second water spray component 30 to the scraper arm body 10, and is beneficial to improving the efficiency of subsequent maintenance.

[0075] In the embodiment of the present application, the first water spraying member 20 includes: a housing 21 and a first water spraying head 22 . The first water spraying head 22 is clamped to the housing 21 , and the housing 21 is clamped to the scraper arm body 10 .

[0076] Specifically, Figure 5 As shown, the shell 21 includes three surfaces, which enclose a receiving cavity. The first water spray head 22 is arranged in the receiving cavity and is clamped to the shell 21 to form a first water spray component 20 as a whole. The first water spray component 20 is clamped to the scraper arm body 10 through the shell 21.

[0077] It should be noted that by setting up the shell 21, an installation space can be provided for the installation of the first water spray head 22. At the same time, since the shell 21 is surrounded by three sides to form an accommodating cavity, the first water spray head 22 is arranged inside the accommodating cavity. When the first water spray component 20 is installed on the scraper arm body 10, the shell 21 can cover the first water spray head 22 from three sides. From the user's perspective, the appearance of the scraper arm is more concise, which is conducive to improving the appearance of the scraper arm and enhancing the user experience.

[0078] In the embodiment of the present application, the first water spray head 22 includes a first water spray pipe 221 and a first clamping portion 222 arranged on the first water spray pipe 221, and the shell 21 is provided with a first clamping groove 214 and a first clamping hole 213 at intervals along the first direction x. The first water spray pipe 221 is clamped in the first clamping groove 214, and the first clamping portion 222 at least partially passes through the first clamping hole 213 and is clamped in the first clamping hole 213.

[0079] Specifically, the first water spray pipe 221 has two connecting ends, one of which is used to connect to a water pipe to transport detergent, and the other connecting end is used to set a first nozzle. The first clamping portion 222 is arranged between the two connecting ends, and the first clamping portion 222 realizes the clamping between the first water spray head 22 and the shell 21. The first clamping portion 222 is provided with a second nozzle to cooperate with the first nozzle to realize water spraying in two different directions of the first water spray member 20. The detergent in the water pipe is transported by the first water spray pipe 221 to the first nozzle and the second nozzle for use by the scraper arm.

[0080] Further, the first slot 214 has an opening, which is arranged along the third direction z and is contracted at the slot end. The first water spray pipe 221 is generally a round tube, so the first slot 214 is also configured to match the round tube. The first water spray pipe 221 can be pressed into the first slot 214 from the opening. The first slot 214 and the first clamping hole 213 are arranged at intervals along the first direction x, which can strengthen the connection between the first water spray head 22 and the housing 21, and further improve the structural stability. The first clamping hole 213 of the housing 21 is also opposite to the first opening on the scraper arm body 10, so that the first water spray head 22 and / or the second water spray head 31 can spray water from the first clamping hole 213 and the first opening.

[0081] In the embodiment of the present application, a first limiting buckle 223 is respectively provided on both sides of the first clamping portion 222 along the first direction x, and a first limiting boss 224 is provided on the side of the first clamping portion 222 away from the first limiting buckle 223 along the second direction y; the first limiting buckle 223 at least partially passes through the first clamping hole 213 and is clamped to the first clamping hole 213, so that the first limiting boss 224 abuts against the shell 21.

[0082] Reference Figure 6 , shows a schematic diagram of the structure of the first water spray head 22 in the embodiment of the present application, such as Figure 6 As shown, the first limit buckle 223 is a "concave" structure, and has a first recessed portion 2232 in the middle along the third direction z. This structure of the first limit buckle 223 enables the first recessed portion 2232 of the first limit buckle 223 to be snapped onto the housing 21. The first limit buckle 223 extends downward along the second direction y, and the limit boss can be an elastic boss, and is arranged on the top of the first snap-fitting portion 222, and the size along the third direction z is smaller than the size of the snap-fitting portion, so that it can be formed into a step shape on the side close to the housing 21. When the two first limit buckles 223 at least partially pass through the first snap-fitting hole 213, the limit boss elastically abuts against the housing 21 above the first snap-fitting hole 213, thereby realizing the snap-fitting between the first water spray head 22 and the housing 21.

[0083] Further, the first limiting buckle 223 includes two first buckles 2231 spaced apart along the third direction z, and one first buckle 2231 passes through the first clamping hole 213 so that the two first buckles 2231 are respectively located on both sides of the first clamping hole 213 along the third direction z.

[0084] Specifically, the first clamping hole 213 is a through hole arranged on the shell 21, and the two first clamping buckles 2231 of the first limiting buckle 223 are arranged to be opposite to each other along the third direction z, and a first recessed portion 2232 is formed between the two first clamping buckles 2231. The first recessed portion 2232 between the two first clamping buckles 2231 abuts against the hole wall of the first clamping hole 213, and the two first clamping buckles 2231 are respectively located on both sides of the shell 21 along the third direction z below the first clamping hole 213, thereby clamping the shell 21 between the two first clamping buckles 2231.

[0085] In addition, both first buckles 2231 are elastic buckles, and one first buckle 2231 passing through the first clamping hole 213 can be set to an arc shape. In practical applications, the first water spray head 22 needs to be installed from one side of the housing 21 along the third direction z, and the first limit buckle 223 is clamped with the first clamping hole 213. Since the first limit buckle 223 includes two first buckles 2231, the first buckle 2231 passing through the first clamping hole 213 is set to an arc shape. Under the action of elasticity, the arc structure can facilitate the first buckle 2231 to slide through the hole wall of the first clamping hole 213, thereby facilitating the assembly between the first water spray head 22 and the housing 21.

[0086] like Figure 5 As shown, in the embodiment of the present application, the housing 21 is further provided with a second buckle 211 and a third buckle 212, such as Figure 7 As shown, the scraper arm body 10 is provided with a second clamping hole 11 and a third clamping hole 12 ; the second clamping buckle 211 is clamped to the second clamping hole 11 , and the third clamping buckle 212 is clamped to the third clamping hole 12 , so as to clamp the first water spraying member 20 to the scraper arm body 10 .

[0087] The second buckle 211 and the third buckle 212 have the same structure but different orientations; the second buckle 211 and the third buckle 212 include a guide surface 215 and an abutting surface 216, wherein the guide surface 215 is an inclined surface. In actual application, the second buckle 211 and the third buckle 212 can move relative to the scraper arm body 10 along the guide surface 215 until the abutting surface 216 abuts against the scraper arm body 10, thereby snapping the second buckle 211 and the third buckle 212 to the scraper arm body 10.

[0088] It should be noted that since the first buckle 2231 is connected to the shell 21 along the second direction y, and the second buckle 211 is connected to the scraper arm body 10 in the first direction x, and the third buckle 212 is connected to the scraper arm body 10 in the third direction z, the first water spray component 20 is limited from the first direction x, the second direction y and the third direction z, thereby strengthening the connection effect between the first water spray component 20 and the scraper arm body 10 and ensuring the connection stability of the first water spray component 20.

[0089] In an embodiment of the present application, the shell 21 includes a first side wall and a second side wall arranged at a preset angle, the first clamping hole 213 is arranged on the first side wall, and the second side wall is also provided with a second clamping hole 11, the first water spray outlet 201 is arranged on the first clamping portion 222, and the second water spray outlet 202 is arranged on the first water spray pipe 221; the first water spray head 22 is clamped on the shell 21 so that the first water spray outlet 201 is at least partially exposed to the first clamping hole 213, and the second water spray outlet 202 is at least partially exposed to the second clamping hole 11.

[0090] Reference Figure 8 , showing a schematic diagram of the structure of the second water spraying member 30 in the embodiment of the present application, referring to Figures 9 and 10 , shows a schematic diagram of the assembly of the second water spray component 30 and the scraper arm body 10 in the embodiment of the present application. In the embodiment of the present application, the second water spray component 30 includes a second water spray head 31, and the second water spray head 31 includes a second water spray pipe 311 and a second clamping portion 312 arranged on the second water spray pipe 311; the second clamping portion 312 at least partially passes through the second opening 13 and is clamped to the second opening 13 to clamp the second water spray component 30 to the scraper arm body 10.

A slope is also provided on the side of the positioning protrusion 315 away from the second clamping portion 312. The setting of the slope facilitates the positioning protrusion 315 to be clamped into the positioning hole 15; the positioning flange 14 is parallel to the top surface of the scraper arm body 10 and extends toward the groove of the scraper arm. The aperture of the positioning hole 15 matches the diameter of the positioning protrusion 315 and is embedded in the positioning hole 15.
