Technical Field

[0001] This application relates to the field of mechanical structures, and in particular, to wiper arms, wipers, and vehicles.

Background Art

[0002] In automobiles, wipers are usually installed on the front windshield to remove rain or dust that obstructs the driver's line of sight, thereby ensuring a clear view for the driver.

[0003] Conventional wipers are installed independently of the cleaning system. The cleaning system is usually arranged under the bonnet, and the cleaning agent is directly sprayed onto the upper central part of the front windshield through a nozzle. As a result, before the wiper wipes off the cleaning agent, the driver cannot clearly see the road conditions ahead, often causing traffic accidents. Also, the spraying path is long, the spraying area is large, and a large amount of cleaning agent is required, resulting in a large waste of resources.

The nozzle 500 used to inject the cleaning liquid onto the front glass is connected to an extension 220 of the wiper arm end piece 200. The extension 220 is provided on the outward swing side B of the wiper arm 10, and the nozzle 500 is connected to the extension 220 toward the return side Z. The wiping area of the wiper including the wiper arm 10 and the wiper blade is defined by a return rest position close to the vehicle's bonnet and an outward swing rest position away from the vehicle's bonnet. Correspondingly, the outward swing side B refers to the side close to the outward swing rest position of the wiper arm 10. As shown in FIG. 1, the outward swing side B is shown as the right side of the wiper arm 10, and the return side Z refers to the side of the wiper arm 10 close to the vehicle's bonnet. As shown in FIG. 1, it should be noted that the return side is shown as the left side of the wiper arm 10.

[0027] In one example, a snap connection is established between the nozzle 500 and the extension 220. Specifically, as shown in FIGS. 3 and 4, the extension 220 extends toward the outward swing side B and includes an intermediate portion 221 and edge portions 222 and 223 on both sides of the intermediate portion 221. The nozzle 500 includes a nozzle body 510, a receiving groove 521, a receiving groove 522, and a hose joint 530. The receiving groove 521, the receiving groove 522, and the hose joint 530 all protrude from one side of the nozzle body 510. The notches of the receiving groove 521 and the receiving groove 522 face each other, and the edge portions 222 and 223 of the extension 220 can be inserted into the receiving groove 521 and the receiving groove 522, respectively. The hose joint 530 is detachably connected to the hose 400.

[0028] Preferably, as shown in FIG. 4, the edges 222 and 223 of the extension part 220 sink with respect to the middle part 221, so that after the nozzle 500 is connected to the extension part 220, the upper surface of the nozzle 500 is substantially flush with the upper surface of the middle part 221, thereby improving the aesthetics of the wiper arm 10.

[0029] In another example, as shown in FIGS. 5 and 6, the extension part 220 includes a middle part 221 and edges 222 and 223 on both sides of the middle part 221. The middle part 221 extends toward the outward swing side B, and the edges 222 and 223 are bent toward the bottom side of the middle part 221 and extend toward each other along the bottom surface of the middle part 221. The nozzle 500 includes a nozzle body 510, a receiving groove 521, a receiving groove 522, and a hose joint 530. The receiving groove 521, the receiving groove 522, and the hose joint 530 all protrude from one side of the nozzle body 510. The notches of the receiving groove 521 and the receiving groove 522 face opposite sides. The edges 222 and 223 of the extension part 220 can be inserted into the receiving groove 521 and the receiving groove 522 respectively, and the hose joint 530 is detachably connected to the hose 400.

[0030] Preferably, as shown in FIGS. 1, 4, and 6, after the nozzle 500 is snap-connected to the extension part 220, the hose joint 530 is shielded by the extension part 220, thereby improving the aesthetics of the wiper arm 10.

[0031] Preferably, as shown in FIGS. 2, 3, 5, and 7, at least one of the edges 222 and 223 is provided with a protrusion 224. Correspondingly, at least one of the receiving groove 521 and the receiving groove 522 is provided with an opening 523. The nozzle 500 can be deformed to fit the protrusion 224 into the opening 523, thereby preventing the nozzle 500 from easily falling off the extension part 220. Here, the protrusion 224 may be triangular or have any other shape.

[0032] As shown in FIGS. 5 and 7, the nozzle body 510 may further include a flow path 511 for the cleaning liquid, and the flow path penetrates the nozzle body 510. Also, the hose joint 530 is in fluid communication with the nozzle body 510, and the cleaning liquid can flow into the nozzle body 510 from the hose joint.

[0033] Preferably, as shown in FIG. 9, at least a part of the extension part 220 is deflected downward by an angle a toward the windshield side with respect to the upper surface of the hook 210. In the examples shown in FIGS. 3 to 5, at least one part includes an intermediate part 221 and edge parts 222 and 223, and in the examples shown in FIGS. 6 to 8, at least one part includes an intermediate part 221. More preferably, since the above-mentioned deflection angle a corresponds to the installation inclination angle of the windshield, when the wiper is installed on the vehicle's windshield, in the observation direction of the driver inside the vehicle, the nozzle 500 and the extension part 220 can block the driver's observation path as little as possible, reduce the interference to the driver by the wiper, and ensure the safety of driving.

[0034] In the above example, it is shown that the nozzle 500 and the extension part 220 are located on the outward swing side B of the wiper arm 10, and the nozzle 500 is connected to the extension part 220 toward the return side Z. However, it should be noted that the nozzle 500 and the extension part 220 may also be located on the return side Z of the wiper arm 10, and it is understood that the nozzle 500 is connected to the extension part 220 toward the outward swing side B.

[0035] According to an embodiment of the present application, the arrangement of the nozzles on the wiper arm ensures that the cleaning liquid can be quickly wiped off, a clear field of vision can be provided to the driver, and the usage amount of the cleaning liquid can also be reduced.

[0036] According to another aspect of the present application, the present application further relates to a wiper including the above-mentioned wiper arm 10 and wiper blade, and the wiper blade is held by the wiper arm end piece 200 of the wiper arm 10.

[0037] According to yet another aspect of the present application, the present application further relates to a vehicle comprising the wiper arm 10 described above or the wiper described above.
