[0046] In order to make the purpose, technical solutions and advantages of this application clearer, the following Figure 1-9 This application is further described in detail. Obviously, the embodiments described are only a part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] It should be understood that although the terms first, second, third, etc. may be used to describe in the embodiments of the present application, these descriptions should not be limited to these terms. These terms are only used to distinguish the descriptions. For example, without departing from the scope of the embodiments of the present application, the first may also be referred to as the second, and similarly, the second may also be referred to as the first.

[0048] Example 1

[0049] An external water-cut structure includes at least one set of external water-cut components 1; the external water-cut components 1 include:

[0050] A first water-cut body 10, wherein a first sealing lip 11 is provided on one side of the first water-cut body 10;

[0051] A scraping structure 12, which is arranged on the upper end surface of the first water-cutting body 10 in a limitable manner and can rotate relative to the first water-cutting body 10;

[0052] The driving device 13 is drivingly connected to the scraping structure 12 and is used to drive the scraping structure 12 to perform a scraping motion.

[0053] Specifically, the outer water-cut structure of the present application can be concealed and arranged on the vehicle door sheet metal 2; wherein, the number of outer water-cut components included in the outer water-cut structure provided by the present application can be adapted and selected according to the length of the vehicle door glass 3. In this embodiment, the outer water-cut structure includes a set of outer water-cut components 1 as an example for detailed description; wherein, one end of the outer water-cut component 1 is arranged adjacent to the bottom corner of the vehicle door frame, and the other end can be arranged to extend along the bottom of the vehicle door frame; this arrangement ensures the stability of the installation of the outer water-cut component 1.

[0054] Furthermore, several snap-fit ​​structures 14 are slidably disposed along the length of the bottom of the first water-cut body 10; the first water-cut body 10 is detachably connected to the vehicle door sheet metal 2 via these snap-fit ​​structures 14. This design has the advantage of facilitating assembly and disassembly of the first water-cut body 10 and the replacement of damaged snap-fit ​​structures 14 during assembly and disassembly, thereby enabling rapid replacement of worn first water-cut body 10. Furthermore, by providing a first sealing lip 11 on one side of the first water-cut body 10 as a sealing structure, the door glass 3 is effectively sealed.

[0055] Furthermore, the positions corresponding to the snap structures 14 on the door sheet metal 2 are all provided with snap-fitting grooves for matching the snap-fitting structures 14; in this embodiment, the snap-fitting structure 14 comprises: a main support rod 141 connected to the bottom of the first water-cut body 10, a limit clamping plate 143 symmetrically arranged on both sides of the upper part of the main support rod 141, a limit elastic clamping foot 144 and an elastic support clamping foot 142 symmetrically arranged on both sides of the bottom of the main support rod 141; the bottom of the first water-cut body 10 is provided with a main support rod 141, a limit clamping plate 143 symmetrically arranged on both sides of the upper part of the main support rod 141, a limit elastic clamping foot 144 and an elastic support clamping foot 142 symmetrically arranged on both sides of the bottom of the main support rod 141; The rod 141 limits the sliding of the opening groove 101; wherein, the cross-sections of the main support rod 141 and the opening groove 101 are both T-shaped structures, and the limiting clamping plate 143 cooperates with the top cover plate of the main support rod 141 to be limitedly installed on the opening groove 101 of the first water-cut body 10; the main support rod 141 is elastically in contact with the upper end surface of the vehicle door sheet metal 2 through the limiting elastic clamping feet 144 on both sides, which can further increase the firmness and stability of the connection between the first water-cut body 10 and the vehicle door sheet metal 2.

[0056] When in use, the main support rod 141 can be slidably installed in the opening groove 101 of the first water-cut body 10 through the top cover plate, and by applying force to the upper end surface of the first water-cut body 10, it can be installed in the clamping groove of the vehicle door sheet metal 2, thereby completing the installation operation of the first water-cut body 10.

[0057] Furthermore, a limiting protrusion 102 is provided on the middle portion of the upper end surface of the first water-cutting body 10 in the longitudinal direction, and correspondingly, a limiting groove 123 is provided on the lower end surface of the scraping structure 12 to engage with the limiting protrusion 102. This design ensures the overall stability of the scraping structure 12 in the initial state and improves its service life.

[0058] Furthermore, the scraping structure 12 includes: a first scraping water-cutting body 120 and a second scraping water-cutting body 121 having the same structure and being relatively rotatable; the first scraping water-cutting body 120 and the second scraping water-cutting body 121 are jointly limited and arranged on the upper end surface of the first water-cutting body 10 through a limiting groove 123 provided at the bottom; wherein the middle part of the upper end surface of the first scraping water-cutting body 120 and the second scraping water-cutting body 121 are both provided with a first scraping lip edge 124 that can contact the surface of the vehicle door glass 3.

[0059] Furthermore, the first scraping and water-cutting body 120 is a short-side structure; the second scraping and water-cutting body 121 is a long-side structure; the first scraping and water-cutting body 120 and the second scraping and water-cutting body 121 can rotate together relative to the first water-cutting body 10 under the action of the driving device 13, and the second scraping and water-cutting body 121 can rotate relative to the first scraping and water-cutting body 120 under the action of the driving device 13.

[0060] In this embodiment, one end of the first scraper and water-sweeper body 120 is positioned at a corner of the bottom of the door frame to provide a fixed support. The second scraper and water-sweeper body 121 is positioned along the bottom of the door frame to sweep away mist, dirt, and the like from the surface of the door glass 3. It will be appreciated that the first scraper and water-sweeper body 120 is designed with a short-side design, while the second scraper and water-sweeper body 121 is designed with a long-side design. This ensures the stability of the connection between the various components while ensuring a stable scraping action. Furthermore, the first and second scraper and water-sweeper bodies 120, 121 can be adjusted in size to accommodate door frames of varying lengths.

[0061] It should be further explained that the external water-cutting structure provided in the present application has two states. In the initial state (i.e., the normal state), the first sealing lip 11 on one side of the first water-cutting body 10 contacts and deforms with the door glass 3 to achieve a sealing effect. At this time, the first scraping lip 124 on the first scraping water-cutting body 120 and the second scraping water-cutting body 121 does not contact the door glass 3, that is, there is a certain gap between the first scraping lip 124 and the door glass 3. In the use state, first, the first scraping water-cutting body 120 and the second scraping water-cutting body 121 rotate synchronously under the action of the driving device 13, moving from the initial position to the predetermined position where the first scraping lip 124 contacts the door glass 3; then, the second scraping water-cutting body 121 can perform a regular rotational scraping motion relative to the first scraping water-cutting body 120 under the action of the driving device 13, thereby removing water mist or dirt formed on the glass surface.

[0062] Furthermore, the first sealing lip 11 of the present application is treated with a flocking layer to increase friction, improve tactile feel, or enhance NHV performance. In this case, the flocking treatment can also help improve sealing effectiveness and reduce wear. To ensure a better sealing effect, the compression of the first sealing lip 11 is controlled between 4mm and 5mm, preferably 4.5mm.

[0063] It should be further explained that the first scraping lip 124 of the present application is made of NCR material (Nitrile Chloroprene Rubber), thereby improving the scraping effect, providing the driver and passengers with a better field of vision, and ensuring driving safety to a greater extent.

[0064] Furthermore, in order to ensure the scraping effect of the first scraping lip 124, the compression amount between the first scraping lip 124 and the door glass 3 is ≥2mm; at the same time, when in use, the gap between the upper end surface of the first scraping water cutting body 120 and the second scraping water cutting body 121 and the door glass 3 is ≥5mm to ensure that there is no abnormal noise during the scraping process.

[0065] Furthermore, the first water-cutting body 10, the first scraping water-cutting body 120, and the second scraping water-cutting body 121 are all covered with a U-shaped support frame 100 along their length. This design ensures the overall strength, stability, and flexibility of the first water-cutting body 10 and the scraping structure 12, thereby ensuring a good sealing and scraping effect.

[0066] Furthermore, the first scraper and water-cutting body 120 has a first end surface 15 convexly formed on one end thereof, which is adjacent to the second scraper and water-cutting body 121. Correspondingly, the second scraper and water-cutting body 121 has a second end surface 16 on the corresponding side thereof, which matches the curvature of the first end surface 15. This design has the advantage that the interaction between the convex first end surface 15 and the concave second end surface 16 reduces physical interference when the second scraper and water-cutting body 121 rotates relative to the first scraper and water-cutting body 120, thereby ensuring stable movement.

[0067] Furthermore, the driving device 13 includes:

[0068] A first drive motor 131 is fixed to the door sheet metal 2 near one end of the first scraper and water-cutting body; an output shaft of the first drive motor 131 is connected to one end of the first scraper and water-cutting body 120 via a first transmission rod 133;

[0069] a second drive motor 132 , which is disposed on the first scraping and water-cutting body 120 , and is configured to drive the second scraping and water-cutting body 121 to rotate relative to the first scraping and water-cutting body 120 ;

[0070] The second transmission rod 134 has one end fixedly connected to the supporting frame 100 inside the second scraping and water-cutting body 121, and the other end passes through the first end surface 15 and is driven and connected to the output shaft of the second drive motor 132; the second transmission rod 134 and the output shaft of the second drive motor 132 are arranged in directions perpendicular to each other, wherein the surface of the first end surface 15 is provided with a strip-shaped avoidance groove for the movement of the second transmission rod 134.

[0071] Specifically, in the initial state, the first scraping water-cutting body 120 and the second scraping water-cutting body 121 are limitedly contacted with the upper end of the first water-cutting body 10; when in use, the first scraping water-cutting body 120 and the second scraping water-cutting body 121 are driven by the first driving motor 131 to rotate from the initial position to the predetermined position; wherein, the predetermined position is the position where the first scraping lip 124 contacts the surface of the vehicle door glass 3; then, the second scraping water-cutting body 121, under the action of the second driving motor 132, performs a reciprocating scraping operation on the surface of the vehicle door glass 3 to complete the cleaning of water mist and dirt on the surface of the vehicle door glass 3.

[0072] In this embodiment, the first and second scraping and water-cutting bodies 120 and 121 rotate from their initial positions to their predetermined positions at an angle of 0° to 40°, thereby controlling the initial and operating states of the first scraping lip 124. This design further offers the advantage of pre-configuring the predetermined operating positions for different vehicle models, thereby meeting the needs of different vehicle types.

[0073] In another embodiment, the outer water-cut structure comprises two sets of outer water-cut assemblies 1, which are installed together at the bottom of the door frame to completely cover the bottom of the door frame. Compared to using a single set of outer water-cut assemblies 1, this has the advantage of better cleaning mist and dirt from the surface of the door glass 3 and a more powerful function. However, it has the disadvantage of requiring a large number of parts, a relatively time-consuming and costly installation process, and is therefore suitable for installation in high-end vehicles.

[0074] It can be understood that the present application can quickly remove water mist and dirt on the surface of the door glass through the scraping structure 12 under special weather conditions, ensuring the clarity of the surface of the door glass 3 during driving, and the driving vision will not be affected, thereby improving safe driving.

[0075] On the other hand, the present application provides a vehicle, comprising a door sheet metal 2, at least one nozzle, a door glass 3 and the external water-cutting structure; wherein the external water-cutting structure can be hidden and detachably connected to the upper part of the door sheet metal 2; a gap channel for the scraping structure 12 to pass through is formed between the inner side of the upper end of the door sheet metal 2 and the door glass 3; at least one of the nozzles is fixed to the upper end of the door sheet metal 2 and is connected to the vehicle's washing system; wherein the spraying direction of the nozzle is always toward the outer surface of the door glass 3.

[0076] The vehicle further includes a control display module; the control module is electrically connected to the washing system and the driving device 13 respectively.

[0077] Specifically, the vehicle provided by the application hides the outer water cutting structure on the upper part of the door panel 2, thereby ensuring the aesthetic effect of the door appearance, and in special weather conditions, the water mist and dirt on the glass surface can be removed by the intelligent opening of the scraping structure 12 in response to the external weather conditions, so as to ensure that the driver's line of sight is not disturbed and the safe driving behavior is ensured.

[0078] Further, the display module can be triggered by an operation instruction or a voice instruction to separately open the cleaning and decontamination function of the door glass 3, that is, by cooperating with the spray head to spray the detergent, the stubborn dirt on the glass surface can be cleaned.

[0079] On the other hand, the application provides an outer water cutting structure control method, comprising the following steps:

[0080] Obtaining a target weather condition outside a target vehicle; the target weather condition at least includes rainy day, snowy day, foggy day;

[0081] In response to the target weather condition, a corresponding first control instruction is output based on a preset mapping relationship between weather condition and power level;

[0082] Based on the first control instruction, an output parameter corresponding to the power level is obtained; the output parameter includes the rotation angle, rotation speed and rotation frequency of the driving device;

[0083] Based on the output parameter, the driving device 13 is operated.

[0084] It can be understood that the application can obtain the output parameter of the driving device 13 through the mapping relationship between the weather condition and the power level in the target weather condition, control the driving device 13 to drive the scraping structure 12 to work, and realize the cleaning operation on the surface of the door glass 3.

[0085] Example

[0086] In the case of light rain, the first driving motor 131 rotates through the output shaft to rotate the first scraping lip 124 by 40° clockwise relative to the initial state, and the interference amount between the first scraping lip 124 and the door glass 3 is 2mm, and then the second driving motor 132 drives the second scraping water cutting body 121 to rotate at a speed of 30rad / min. For example, in heavy rain, the second driving motor 132 drives the second scraping water cutting body 121 to rotate at a speed of 80rad / min.

[0087] It can be understood that the application can intelligently open the cleaning function of the door glass surface in special weather conditions, so as to ensure that the driver's line of sight is not affected and improve the driving safety behavior.

[0088] Now, exemplary embodiments according to the present application will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of this application thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art. In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.
