The vehicle windshield wiper structure includes a wiper body, an air jet mechanism, a swivel sensor, and an air compressor. The air jet mechanism includes a main air duct and multiple air jet ducts, the main air duct being connected to the multiple air jet ducts and the air compressor. The swivel sensor detects the rotation angle of the wiper body, and the air compressor provides compressed air to each air jet duct through the main air duct for cleaning a preset area.

Description

Technical Field

[0001] This application relates to the field of vehicle windshield wiper technology, and more particularly to a windshield wiper structure and vehicle. Background Technology

[0002] In adverse weather conditions, such as rain, snow, or sandstorms, windshield wipers effectively remove rain, snow, or sand accumulated on the windshield, preventing obstruction of vision. Therefore, to improve driving safety in inclement weather, windshield wipers have become an essential component of modern vehicles.

[0003] In existing technology, to avoid interference between the windshield wipers and the pillars on both sides of the windshield (i.e., A-pillars), a gap of approximately 60mm is usually set between the extreme position of the wiper swing and the A-pillar. Since this gap is outside the wiping range of the wipers, dirt often accumulates here due to inadequate cleaning over a long period of time, making it difficult to wipe away effectively, affecting the driver's visibility, and this is especially noticeable when driving in the rain.

[0004] Therefore, this will result in a limited wiping range of the windshield wipers during rainy driving, leading to incomplete wiping, poor driving visibility, and affecting driving safety. Summary of the Invention

[0005] This application provides a windshield wiper structure and a vehicle to solve the problems of limited wiping range and incomplete wiping of existing windshield wipers, resulting in poor driving visibility and low driving safety.

[0006] To achieve the above objectives, this application adopts the following technical solution:

[0007] This application provides a windshield wiper structure for a vehicle, including a wiper body, an air jet mechanism, a swivel sensor, and an air compressor. The air jet mechanism and the swivel sensor are disposed on the wiper body. The air jet mechanism includes a main air duct and multiple air jet ducts, the main air duct being connected to the multiple air jet ducts and the air compressor. The swivel sensor is used to detect the rotation angle of the wiper body. When the rotation angle of the wiper body is greater than or equal to a preset rotation angle, the air jet ducts open, and the air compressor provides compressed air through the main air duct to each air jet duct for cleaning a preset area, the preset area being outside the swing range of the wiper body. When the rotation angle of the wiper body is less than the preset rotation angle, the air jet ducts close.

[0008] In one possible implementation, the windshield wiper structure of the vehicle provided in this application includes a wiper body comprising a wiper housing, the wiper housing having a cavity, the cavity extending in the same direction as the wiper housing, the cavity constituting a main air passage; and a plurality of through holes communicating with the cavity are provided on one side of the wiper housing, the through holes constituting an air jet passage.

[0009] In one possible implementation, the windshield wiper structure of the vehicle provided in this application has multiple air jet passages spaced apart along the extension direction of the wiper housing.

[0010] In one possible implementation, the windshield wiper structure of the vehicle provided in this application further includes a piston switch in the jet mechanism. The piston switch includes a piston, an air passage baffle, and an electromagnetic control component. The piston is disposed on the wiper housing. The air passage baffle is fixedly connected to the piston, and the area of ​​the air passage baffle is not less than the area of ​​the jet air passage. The air passage baffle is used to open or close the jet air passage under the action of the piston. The electromagnetic control component is electrically connected to the angle controller and is used to control the piston movement to drive the air passage baffle to open or close the jet air passage.

[0011] In one possible implementation, the windshield wiper structure of the vehicle provided in this application has an air passage baffle inserted into a cavity.

[0012] In one possible implementation, the windshield wiper structure of the vehicle provided in this application includes a piston comprising a piston plate and a piston slide, the piston slide being disposed on the wiper housing, the piston plate being inserted into the piston slide and slidingly engaged with the piston slide; an air passage baffle being fixedly connected to the piston plate; and an electromagnetic control component being used to control the movement of the piston plate relative to the piston slide.

[0013] In one possible implementation, the windshield wiper structure of the vehicle provided in this application includes an electromagnetic control component comprising an electromagnetic coil and a magnet. The electromagnetic coil is disposed on the wiper housing and is electrically connected to a slewing angle sensor. The magnet is disposed on a piston plate and is located at the end of the piston plate near the electromagnetic coil. When the rotation angle of the wiper body is greater than or equal to a preset rotation angle, the electromagnetic coil attracts the magnet, and the piston plate drives the air passage baffle to move relative to the wiper housing, so that the air passage baffle is misaligned with the air jet passage.

[0014] In one possible implementation, the windshield wiper structure of the vehicle provided in this application further includes a return spring in the electromagnetic control component. The return spring is disposed between the piston plate and the piston slide, and the return spring is located at the end of the piston plate away from the electromagnetic coil. When the rotation angle of the wiper body is less than the preset rotation angle, the electromagnetic coil is disengaged from the magnet, and the return spring drives the air passage baffle to move in the opposite direction relative to the wiper housing so that the air passage baffle covers the air jet passage.

[0015] In one possible implementation, the windshield wiper structure of the vehicle provided in this application further includes an air duct, one end of which is connected to the main air passage and the other end of which is connected to an air compressor; an air valve is provided on the air duct, and the air valve is electrically connected to a slewing angle sensor; the air valve is used to control the air duct to open when the rotation angle of the wiper body is greater than or equal to a preset rotation angle, and to control the air duct to close when the rotation angle of the wiper body is less than the preset rotation angle.

[0016] This application also provides a vehicle, including a controller and a windshield wiper structure as described in any of the preceding claims. The windshield wiper structure includes a slewing angle sensor, which is electrically connected to the controller. The controller controls the air jet passage to open when the rotation angle of the wiper body is greater than or equal to a preset rotation angle, and controls the air jet passage to close when the rotation angle of the wiper body is less than the preset rotation angle.

[0017] This application provides a windshield wiper structure and a vehicle. By setting an air jet mechanism and a rotation angle sensor on the wiper body, the air jet mechanism can spray compressed air when the rotation angle of the wiper body is greater than or equal to a preset rotation angle. The compressed air is then used to clean a preset area outside the actual wiping area of ​​the wiper body, thereby expanding the wiping range of the wiper and improving the wiping efficiency, thus achieving the purpose of expanding the driver's field of vision and improving driving safety.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. In the absence of conflict, the following embodiments and features can be combined with each other.

[0034] In existing technologies, during adverse weather conditions such as rain, snow, or sandstorms, windshield wipers can effectively remove rainwater, snow, or sand accumulated on the windshield, preventing obstruction of vision and ensuring driver safety. Therefore, windshield wipers have become one of the essential devices for improving driving safety in vehicles today.

[0035] During the actual wiping process, the vehicle frame has A-pillars at both ends of the wiper's wiping path. These A-pillars are uprights on either side of the windshield, used to secure it. To prevent excessive wiper swing and interference with the A-pillars, a gap of approximately 60mm is typically maintained between the wiper's extreme swing angle and the A-pillar. However, this gap is outside the wiper's wiping range. With long-term accumulation of dirt and inadequate cleaning, this dirt is difficult to remove effectively, affecting the driver's visibility. Furthermore, raindrops falling into this gap on the windshield, as well as water wiped away by the wipers, also obstruct the driver's view during rainy weather.

[0036] Therefore, this will limit the wiping range of the windshield wipers during rainy driving, resulting in incomplete wiping and further reducing driving visibility, thus affecting driving safety.

[0037] In order to overcome the defects in the prior art, this application provides a windshield wiper structure and a vehicle to solve the problems of limited wiping range and incomplete wiping of existing windshield wipers, resulting in poor driving visibility and low driving safety.

[0038] The present invention will now be described in detail with reference to the accompanying drawings, so that those skilled in the art can have a clearer and more detailed understanding of the present invention.

[0039] The following combination Figures 1 to 6 This application provides a detailed description of the windshield wiper structure and the vehicle itself.

[0040] like Figure 1 As shown, the windshield wiper structure of the vehicle provided in this application includes a wiper body 100, an air jet mechanism 200, a cornering sensor 300, and an air compressor 400. The air jet mechanism 200 and the cornering sensor 300 are disposed on the wiper body 100.

[0041] like Figure 1 and Figure 5 As shown, the jet mechanism 200 includes a main air duct 210 and multiple jet air ducts 211. The main air duct 210 is connected to the multiple jet air ducts 211 and is also connected to an air compressor 400. An angle sensor 300 is used to detect the rotation angle of the wiper body 100. When the rotation angle of the wiper body 100 is greater than or equal to a preset rotation angle, the jet air ducts 211 open, and the air compressor 400 provides compressed air through the main air duct 210 to each jet air duct 211 for cleaning a first preset area 620, which is located outside the swing range of the wiper body 100. When the rotation angle of the wiper body 100 is less than the preset rotation angle, the jet air ducts 211 close.

[0042] Understandably, the wiper body 100 includes a wiper assembly 110, a wiper arm 120, and a drive linkage. The wiper assembly 110 is used to directly contact the windshield 600 to achieve the wiping action; the wiper arm 120 is hinged to the wiper assembly 110 and is used to drive the wiper assembly 110 to swing synchronously through its own swing; the drive linkage is connected to the wiper arm 120 through transmission, and the drive linkage can perform reciprocating motion through the rotation of the motor, thereby driving the wiper arm 120 to swing.

[0043] The jet injection mechanism 200 is mounted on the wiper assembly 110 of the wiper body 100, thereby ensuring synchronized operation between the jet injection mechanism 200 and the wiper assembly 110 and improving the jet injection efficiency of the jet injection mechanism 200. The angle sensor 300 is mounted on the wiper arm 120, and controls the jet injection mechanism 200 to more sensitively sense the rotation angle of the wiper body 100, resulting in higher accuracy and efficiency of compressed air injection.

[0044] The main air duct 210 of the jet mechanism 200 is directly or indirectly connected to the air compressor 400. The jet duct 211 is connected to the main air duct 210, so that the air compressor 400 can provide compressed air to the jet duct 211, so that the wiper body 100 sprays compressed air while wiping, cleaning areas that cannot be directly wiped by the wiper assembly 110 alone, thereby expanding the wiping range of the wiper and improving the wiping efficiency.

[0045] It should be noted that the preset rotation angle is not unique, but it must not exceed the maximum rotation angle of the wiper arm 120. Assuming the maximum rotation angle of the wiper arm 120 is 45°, then 43° can be set as the preset rotation angle. Therefore, when the wiper arm 120 of the wiper body 100 rotates 43° from its initial position, the air jet duct 211 will eject compressed air to clean the first preset area 620 located between the wiper assembly 110 and the A-pillar 610. During this process, the air jet duct 211 can continuously eject compressed air until the wiper arm 120 rotates to 45° and then returns to 43°, at which point the ejection of compressed air stops; alternatively, the air jet duct 211 can also eject a set amount of compressed air all at once when the wiper arm 120 rotates to 43°, and close the air jet duct 211 when the wiper arm 120 returns to 43°. This embodiment does not impose specific limitations here.

[0046] Furthermore, it should be noted that the preset areas on the windshield 600 in this embodiment mainly include the first preset area 620 located between the maximum rotation angle position of the wiper body 100 and the A-pillar 610, and may also include the second preset area 630 located outside the arc of the actual wiping range of the wiper body 100. This can be achieved by adjusting the setting position of the air jet duct 211 on the wiper body to meet the cleaning needs of different preset areas. This embodiment does not impose any limitations on this.

[0047] It is understood that the windshield wiper structure of this embodiment, by providing an air jet mechanism 200 and a rotation angle sensor 300 on the wiper body 100, uses compressed air provided by the air compressor 400 to clean the first preset area 620 when the rotation angle of the wiper body 100 is greater than or equal to a preset rotation angle. This can expand the actual wiping range of the wiper body 100 and also improve the wiping efficiency of the wiper.

[0048] Optional, such as Figure 1 , Figure 2 and Figure 5 As shown, the wiper body 100 also includes a wiper housing 111, which has a cavity. The extension direction of the cavity is consistent with the extension direction of the wiper housing 111, and the cavity constitutes the main air passage 210. A plurality of through holes communicating with the cavity are provided on one side of the wiper housing 111, and the through holes constitute the air jet passage 211.

[0049] It should be noted that the wiper housing 111 is the housing of the wiper assembly 110. Therefore, a cavity is provided inside the wiper housing 111 as the main air passage 210, and multiple through holes communicating with the cavity are provided on one side of the wiper housing 111 as air jet passages 211. This means that the air jet mechanism 200 is directly machined on the housing of the wiper assembly 110 itself, avoiding the need to set up an additional housing for the air jet mechanism 200 and connect it to the housing of the wiper assembly 110, making the vehicle's wiper structure more compact and lightweight.

[0050] Furthermore, since the jet passage 211 is composed of a through hole communicating with the cavity, the jet angle and jet orientation of the jet passage 211 can be adjusted by changing the specific machining angle and machining position of the through hole. For example, as Figure 6 As shown, by machining a through hole at a 45° angle to the windshield 600, compressed air can be sprayed from the jet duct 211 at a 45° angle to the first preset area 620. Furthermore, a through hole can be opened at the end of the wiper housing 111 away from the wiper arm 120 to form a jet duct 211 that extends in the same direction as the main air duct 210. Using this jet duct 211, air can be sprayed to the second preset area 630 outside the arc of the actual wiping range of the wiper body 100, further improving the utilization rate of the jet duct 211 and expanding the jet range of the jet mechanism 200. This can be adjusted according to the specific usage requirements of the jet mechanism 200, and this embodiment does not impose any limitations.

[0051] Optional, such as Figure 2 and Figure 5 As shown, multiple air jet channels 211 are spaced apart along the extension direction of the wiper housing 111.

[0052] Therefore, it can be assumed that the through holes used to form the jet passages 211 are mainly located on the side of the wiper housing 111 near the A-pillar 610. Each jet passage 211 is parallel and maintains a consistent spacing with each other, so that the jet density distribution of the jet mechanism 200 is more uniform, improving the overall effect of jet cleaning and making it easier for the jet mechanism 200 to clean the first preset area 620.

[0053] Optional, such as Figure 3 As shown, the jet mechanism 200 also includes a piston switch 220, which includes a piston 221, an air passage baffle 223, and an electromagnetic control assembly 224. The piston 221 is mounted on the wiper housing 111. The air passage baffle 223 is fixedly connected to the piston 221, and its area is not less than the area of ​​the jet passage 211. The air passage baffle 223 is used to open or close the jet passage 211 under the action of the piston 221. The electromagnetic control assembly 224 is electrically connected to the steering controller and is used to control the movement of the piston 221 to drive the air passage baffle 223 to open or close the jet passage 211.

[0054] It is understandable that by setting a piston switch 220 on the jet mechanism 200, the opening and closing of the jet passage 211 can be controlled, making the vehicle's windshield wiper structure more refined and facilitating flexible and safe control of the jet mechanism 200.

[0055] It should be noted that, to facilitate the installation and control of the piston switch 220, multiple pistons 221 can be arranged along the extension direction of the wiper housing 111, and the pistons 221 are positioned outside the wiper housing 111. The number of air passage baffles 223 should be consistent with the number of jet air passages 211, and the air passage baffles 223 located within the same piston 221 length range are fixedly connected to the piston 221 through the same connecting part 2231. The connecting part 2231 makes the air passage baffles 223 perpendicular to the piston 221, thereby facilitating the installation of the piston 221 and the air passage baffles 223, and also facilitating the piston 221 to move multiple air passage baffles 223 at one time, controlling the opening or closing of the jet air passages 211, and improving the control efficiency of the piston 221. By ensuring that the area of ​​the air passage baffles 223 is not less than the area of ​​the jet air passages 211, it is also easy to ensure that the air passage baffles 223 can effectively close the jet air passages 211.

[0056] In some embodiments, the piston 221 may also be disposed inside the wiper housing 111 to make the wiper structure of the vehicle more compact, which is not limited herein.

[0057] The movement of the piston 221 is controlled by the electromagnetic control component 224, and the electromagnetic control component 224 is electrically connected to the angle sensor 300. This enhances the consistency and reliability of the vehicle's wiper structure and simplifies the control process. Furthermore, the inherent controller of the vehicle's wiper structure can be used to control the on / off state of the air jet duct 211 without connecting the angle sensor 300 to the vehicle's controller, making the vehicle's wiper structure more independent and facilitating independent control and maintenance. Alternatively, the angle sensor 300 can be directly electrically connected to the vehicle's own controller, saving on the cost of the vehicle's wiper structure; this embodiment does not impose specific limitations on this approach.

[0058] Optionally, the airway baffle 223 is inserted into the cavity.

[0059] It should be noted that regardless of whether the piston 221 is located inside or outside the wiper housing 111, the air passage baffle 223 can be inserted into the cavity of the wiper housing 111. This makes the vehicle's wiper structure more compact and prevents external impurities from blocking the movement of the air passage baffle 223. It also facilitates the air passage baffle 223 to press tightly against the wiper housing 111 from the inside, improving the sealing effect of the air passage baffle 223 on the air jet passage 211. However, when the piston 221 is located outside the wiper housing 111, a strip-shaped through hole needs to be made on the wiper housing 111, consistent with the movement path of the air passage baffle 223, so that the air passage baffle 223 can be inserted into the cavity.

[0060] In some examples, the air passage baffle 223 can also be set on the outside of the wiper housing 111, so that the air passage baffle 223 covers the jet air passage 211 from the outside of the wiper housing 111, thereby realizing the on / off control of the jet air passage 211. Correspondingly, the piston 221 needs to be adapted. This embodiment does not impose specific limitations here.

[0061] Optional, such as Figure 3 and Figure 4 As shown, piston 221 includes piston plate 2211 and piston slide 2212. Piston slide 2212 is disposed on wiper housing 111, and piston plate 2211 is inserted into piston slide 2212, with piston plate 2211 and piston slide 2212 in sliding engagement. Air passage baffle 223 is fixedly connected to piston plate 2211. Electromagnetic control assembly 224 is used to control the movement of piston plate 2211 relative to piston slide 2212.

[0062] It should be noted that the piston slide 2212 is attached to the top of the wiper housing 111, and the piston slide 2212 has a groove that extends in the same direction as the wiper housing 111. The piston plate 2211 is inserted into this groove, also located above the wiper housing 111, and the piston plate 2211 can slide parallel to the upper surface of the wiper housing 111 within the groove, thereby enabling the piston plate 2211 and the piston slide 2212 to slide in cooperation. A connecting portion 2231 is provided at the upper end of the air passage baffle 223 located within the length range of the piston plate 2211. Multiple air passage baffles 223 are fixedly connected to this connecting portion 2231, and the connecting portion 2231 is fixedly connected to the air passage baffles 223. The connecting portion 2231 allows the air passage baffles 223 to be perpendicular to the piston plate 2211 and parallel to the side of the wiper housing 111 where the air jet passage 211 is located.

[0063] By utilizing the electromagnetic control component 224, the piston plate 2211 can reciprocate within the groove of the piston slide 2212 relative to the piston slide 2212, and the air passage baffle 223 moves synchronously with the piston plate 2211, thereby realizing the opening and closing control of the jet air passage 211.

[0064] Optionally, the electromagnetic control assembly 224 includes an electromagnetic coil 2241 and a magnet 2242. The electromagnetic coil 2241 is disposed on the wiper housing 111 and is electrically connected to the angle sensor 300. The magnet 2242 is disposed on the piston plate 2211 and is located at the end of the piston plate 2211 near the electromagnetic coil 2241. When the rotation angle of the wiper body 100 is greater than or equal to a preset rotation angle, the electromagnetic coil 2241 attracts the magnet 2242, and the piston plate 2211 drives the air passage baffle 223 to move relative to the wiper housing 111, so that the air passage baffle 223 is misaligned with the air jet passage 211.

[0065] It is understandable that the electromagnetic control assembly 224, composed of electromagnetic coil 2241 and magnet 2242, has a relatively simple structure and is easy to install. By energizing the electromagnetic coil 2241, it can be made magnetic, thereby attracting the magnet. Therefore, the electromagnetic coil 2241 can be placed on a mechanism or component that is stationary relative to the magnet 2242, such as the wiper housing 111 or the piston slide 2212, while the magnet 2242 is placed at the end of the piston plate 2211 close to the electromagnetic coil 2241. In this way, by energizing the electromagnetic coil 2241, the piston plate 2211 is attracted to move towards the electromagnetic coil 2241, which drives the air passage baffle 223 to move relative to the wiper housing 111.

[0066] It should be noted that the air passage baffle 223 normally covers the jet passage 211, keeping the jet passage 211 in a closed state. However, when the electromagnetic coil 2241 is energized, the air passage baffle 223 can move until it is misaligned with the jet passage 211, thus opening the jet passage 211. To ensure that the jet passage 211 is normally closed and opens when the electromagnetic coil 2241 is energized, a gap must be maintained between the electromagnetic coil 2241 and the magnet 2242 when the jet passage 211 is closed. Furthermore, the same gap must be maintained between the piston plate 2211 and the end of the piston slide 2212 where the electromagnetic coil 2241 is located. This allows the magnet 2242 on the piston plate 2211 to be attracted when the electromagnetic coil 2241 is energized, thus misaligning the air passage baffle 223 with the jet passage 211.

[0067] Therefore, when the rotation angle of the wiper body 100 is greater than or equal to the preset rotation angle, the angle sensor 300 sends a signal, the electromagnetic coil 2241 is energized and attracts the magnet 2242, causing the piston plate 2211 connected to the magnet 2242 to drive the air passage baffle 223 to move relative to the wiper housing 111, so that the air passage baffle 223 is misaligned with the air jet passage 211.

[0068] Optionally, the electromagnetic control assembly 224 further includes a return spring 2243, which is disposed between the piston plate 2211 and the piston slide 2212, and is located at the end of the piston plate 2211 away from the electromagnetic coil 2241. When the rotation angle of the wiper body 100 is less than a preset rotation angle, the electromagnetic coil 2241 disengages from the magnet 2242, and the return spring 2243 drives the air passage baffle 223 to move in the opposite direction relative to the wiper housing 111, so that the air passage baffle 223 covers the air jet passage 211.

[0069] It is understandable that, in order to enable the piston plate 2211 to move in opposite directions within the piston slide 2212, if a reset element is not provided at the other end of the piston plate 2211, then the same electromagnetic coil 2241 and magnet 2242 need to be provided so that the electromagnetic coil 2241 can attract the magnet 2242 from the other end, causing it to move in the opposite direction. Therefore, in some examples, the wiper housing 111 or the piston slide 2212 is provided with electromagnetic coils 2241 at both ends of the piston plate 2211, and magnets 2242 are provided at both ends of the piston plate 2211 to achieve bidirectional movement of the piston plate 2211. This embodiment does not limit this.

[0070] Therefore, to avoid having too many electromagnetic control components 224, making its structure overly complex and inconvenient to control, a return spring 2243 can be installed at the end of the piston plate 2211 away from the electromagnetic coil 2241. One end of the return spring 2243 is connected to the wiper housing 111 or the piston slide 2212, and the other end is connected to the piston plate 2211. When the electromagnetic coil 2241 attracts the magnet 2242, the return spring 2243 is in an extended and tensioned state. Thus, when the electromagnetic coil 2241 is de-energized and disengaged from the magnet 2242, the return spring 2243 automatically retracts, driving the piston plate 2211 to move, causing the air passage baffle 223 to cover the jet passage 211 again.

[0071] Therefore, when the rotation angle of the wiper body 100 is less than the preset rotation angle, the angle sensor 300 sends a signal to disengage the electromagnetic coil 2241 from the magnet 2242, and the return spring 2243 contracts. The return spring 2243 drives the air passage baffle 223 to move in the opposite direction relative to the wiper housing 111 so that the air passage baffle 223 covers the air jet passage 211.

[0072] Optional, such as Figure 1 As shown, the vehicle's windshield wiper structure also includes an air duct 500, one end of which is connected to the main air duct 210, and the other end is connected to the air compressor 400. An air valve 510 is installed on the air duct 500, and the air valve 510 is electrically connected to the angle sensor 300. The air valve 510 controls the air duct 500 to open when the rotation angle of the wiper body 100 is greater than or equal to a preset rotation angle, and controls the air duct 500 to close when the rotation angle of the wiper body 100 is less than the preset rotation angle.

[0073] Understandably, by providing an air duct 500 between the jet mechanism 200 and the air compressor 400, the installation position of the air compressor 400 can be made more flexible, and the swing of the wiper body 100 can be facilitated without interference. Connecting the air duct 500 to the middle of the main air passage 210 facilitates the even distribution of compressed air within the main air passage 210 to the jet passage 211. The air duct 500 is also partially inserted into a part of the structure of the wiper body 100, specifically into the wiper arm 120, or it can be bundled together with the wiper arm 120 to make its structure more compact.

[0074] It should be noted that an air valve 510 is installed on the air duct 500. The air valve 510 is also electrically connected to the angle sensor 300. The angle sensor 300 can control the opening and closing of the air valve 510, so that the air valve 510 and the piston switch 220 cooperate to control the flow of compressed air, so as to achieve precise control of the vehicle's wiper structure.

[0075] Thus, when the rotation angle of the wiper body 100 is greater than or equal to the preset rotation angle, the angle sensor 300 sends a signal, the air valve 510 opens, and the air duct 500 is unobstructed to allow compressed air to flow. When the rotation angle of the wiper body 100 is less than the preset rotation angle, the angle sensor 300 sends a signal, the air valve 510 closes, and the air duct 500 is blocked, interrupting the flow of compressed air.

[0076] The following combination Figure 1 and Figure 6 The working process of a vehicle's windshield wiper structure will be explained in detail:

[0077] 1. When the vehicle starts, the air compressor 400 turns on and pressurizes the air to two atmospheres, which is 2.026 × 10⁻⁶. 5 Pa, and wait for the wiper body 100 to start working;

[0078] 2. When the wiper body 100 starts working, the angle sensor 300 starts operating. The limit angle position of the wiper body 100 is set to 45°. When the angle sensor 300 detects that the rotation angle of the wiper body 100 reaches 43°, it sends a signal to the air valve 510, causing the air valve 510 to open and the air duct 500 to be open. At this time, compressed air enters the main air passage 210 of the jet mechanism 200 through the air duct 500 and is dispersed to the jet passage 211, waiting to be sprayed out.

[0079] 3. When the angle sensor 300 detects that the wiper body 100 has rotated to 43°, it sends a signal to the air valve 510 and also sends a signal to the piston switch 220, causing the piston switch 220 located on the wiper housing 111 to start actuating, energizing the electromagnetic coil 2241. The electromagnetic coil 2241 attracts the magnet 2242, which drives the piston plate 2211, along with the air passage baffle 223, to move until the air passage baffle 223 is misaligned with the jet air passage 211, causing the jet air passage 211 to open and compressed air to be ejected from the jet air passage 211. The ejected compressed air has an angle of about 45° with the first preset area 620.

[0080] Based on practical experience and the ideal gas law PV=nRT (where P is the gas pressure, taken as two atmospheres, 2.026×10⁻⁶), 5Pa, V is the gas volume, which is determined according to the specific parameters of the wiper housing 111 cavity, n is the amount of substance, which is determined according to the specific parameters of the wiper housing 111 cavity, R is the gas constant, and T is the temperature (taken as room temperature). Combined with the pressure formula P=F / S (taking S as the area of ​​the first preset region 620), it can be calculated that an instantaneous blowing force of about 24500N is generated. This blowing force is sufficient to clean the first preset region 620, thereby expanding the wiping range of the wiper and improving the wiping efficiency of the wiper.

[0081] 4. When the angle sensor 300 detects that the wiper body 100 starts to move back, the electromagnetic coil 2241 is de-energized, causing the magnet 2242 to disengage from the electromagnetic coil 2241. The return spring 2243 retracts and pulls the piston plate 2211 to move in the opposite direction, causing the air passage baffle 223 to cover the jet passage 211, thus closing the jet passage 211.

[0082] 5. When the angle sensor 300 detects that the windshield wiper body 100 has returned to 43°, the angle sensor 300 sends a signal to the air valve 510 to close the air valve 510.

[0083] 6. When the wiper body 100 runs again, steps 2-5 above will be repeated.

[0084] It should be noted that when it is necessary to clean the second preset area 630 outside the arc of the actual wiping range of the wiper body 100, it is necessary to set the first preset rotation angle and the second preset rotation angle. The second preset rotation angle is still 43°, while the first preset rotation angle can be 15°, or it can be determined according to specific needs. Corresponding to the first preset rotation angle, an air jet channel 211 is provided at the end of the wiper housing 111 in the same direction as the extension of the wiper housing 111. The remaining air jet channels 211 are provided on one side of the wiper housing 111.

[0085] At this point, steps 2-5 should be:

[0086] 2. When the angle sensor 300 detects that the rotation angle of the wiper body 100 reaches 15°, it sends a first signal to the air valve 510, causing the air valve 510 to open and the air duct 500 to be open. At this time, compressed air enters the main air passage 210 of the jet mechanism 200 through the air duct 500 and is dispersed to the jet passage 211, waiting to be sprayed out.

[0087] 3. When the angle sensor 300 detects that the wiper body 100 has rotated at an angle of 15°, it sends a first signal to the air valve 510 and also sends a first signal to the piston switch 220, causing the piston switch 220 located at the end of the wiper housing 111 to start operating. The electromagnetic coil 2241 is energized, and the electromagnetic coil 2241 attracts the magnet 2242. The magnet 2242 drives the piston plate 2211, together with the air passage baffle 223, to move until the air passage baffle 223 is misaligned with the air jet passage 211 at the end of the wiper housing 111, so that the air jet passage 211 is opened and compressed air is continuously ejected from the air jet passage 211. When the angle sensor 300 detects that the wiper body 100 has rotated at an angle of 43°, it sends a second signal, causing the air jet passage 211 located on one side of the wiper housing 111 to open and eject compressed air.

[0088] 4. When the angle sensor 300 detects that the wiper body 100 starts to move back, the electromagnetic coil 2241 is de-energized, causing the magnet 2242 to disengage from the electromagnetic coil 2241. The return spring 2243 retracts and pulls the piston plate 2211 to move in the opposite direction, causing the air passage baffle 223 to cover the jet air passage 211, thus closing the jet air passage 211 together.

[0089] 5. When the angle sensor 300 detects that the rotation angle of the wiper body 100 has returned to 43°, i.e. the second preset rotation angle, the angle sensor 300 sends a signal to the air valve 510 to close the air valve 510.

[0090] like Figure 1 As shown in the embodiments of this application, a vehicle is also disclosed, including a controller and a windshield wiper structure as provided in any of the foregoing technical solutions. The windshield wiper structure includes a slewing angle sensor 300, which is electrically connected to the controller. When the rotation angle of the wiper housing is greater than or equal to a preset rotation angle, the controller controls the air jet passage 211 to open. When the rotation angle of the wiper housing is less than the preset rotation angle, the controller controls the air jet passage 211 to close.

[0091] The remaining structure and working principle of the vehicle's windshield wiper have been described in detail in the above embodiments, and will not be repeated here.

[0092] In summary, the windshield wiper structure and vehicle provided in this embodiment include a jetting mechanism 200 and a slewing sensor 300 mounted on the wiper body 100, with an air compressor 400 and the jetting mechanism 200 connected via an air duct 500. This allows the jetting mechanism 200 to eject compressed air when the rotation angle of the wiper body 100 is greater than or equal to a preset rotation angle. This compressed air then cleans a first preset area 620 or a second preset area 630 outside the actual wiping area of ​​the wiper body 100. This expands the wiping range of the wiper and improves its wiping efficiency, thereby enhancing driving visibility and improving driving safety.
