[0046] In order to make the purpose, technical solutions and advantages of this application clearer, the following will be combined with the attached Figure 1-9 The present application is further described in detail. Obviously, the described embodiments are only a part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the present 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 can be arranged on the upper end surface of the first water-cutting body 10 in a limited 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 for driving the scraping structure 12 to perform a scraping motion.

[0053] Specifically, the outer water cut structure of the present application can be hidden and arranged on the 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 selected and adapted according to the length of the door glass 3. In this embodiment, a detailed description is given by taking the outer water cut structure including a group of outer water cut components 1 as an example; wherein, one end of the outer water cut component 1 is arranged adjacent to the bottom corner of the door frame, and the other end can be arranged extending along the bottom of the door frame; this arrangement ensures the stability of the installation of the outer water cut component 1.

[0054] Furthermore, a plurality of buckle structures 14 are slidably provided in the length direction of the bottom of the first water-cut body 10; the first water-cut body 10 is detachably connected to the door sheet metal 2 through the plurality of buckle structures 14. The advantage of this design is that, through the design of the buckle structure 14, it is easy to disassemble and assemble the first water-cut body 10 and replace the buckle structure 14 damaged during the disassembly and assembly process, so that the worn first water-cut body 10 can be quickly replaced; secondly, by using the first sealing lip 11 provided on one side of the first water-cut body 10 as a sealing structure, the sealing effect of the door glass 3 can be guaranteed.

[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 elastic support clamping feet 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 for matching 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 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 length direction of the upper end surface of the first water-cutting body 10, and correspondingly, a limiting groove 123 is provided on the lower end surface of the scraping structure 12 to be inserted with the limiting protrusion 102. This design can ensure the overall stability of the scraping structure 12 in the initial state and improve 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 of the same structure and 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 set 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 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 be rotated 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 be rotated 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-cut body 120 is arranged at the corner of the bottom of the door frame to play a role of fixed support; the second scraper and water-cut body 121 is arranged along the bottom of the door frame to scrape water mist and dirt on the surface of the door glass 3. It can be understood that the length of the first scraper and water-cut body 120 is designed for the short side, and the length of the second scraper and water-cut body 121 is designed for the long side, thereby ensuring the connection stability of each component and ensuring the stability of the scraping action, and can be adapted to door frames with different lengths by adjusting the size of the first scraper and water-cut body 120 and the second scraper and water-cut body 121.

[0061] It should be further explained that the external water-cut 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-cut body 10 is in contact with the door glass 3 and deformed to play a sealing role. At this time, the first scraping lip 124 on the first scraping water-cut body 120 and the second scraping water-cut body 121 is not in contact with 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-cut body 120 and the second scraping water-cut body 121 are synchronously rotated under the action of the driving device 13, and move from the initial position to the predetermined position where the first scraping lip 124 contacts the door glass 3; then, the second scraping water-cut body 121 can perform regular rotational scraping motion relative to the first scraping water-cut body 120 under the action of the driving device 13, so as to remove water mist or dirt formed on the glass surface.

[0062] Furthermore, the surface of the first sealing lip 11 of the present application is formed with a flocking layer by a flocking treatment process, thereby increasing the friction force on the surface of the first sealing lip 11, improving the touch or improving the NHV performance. In this case, the flocking treatment can also help to improve the sealing effect and reduce wear. In order to better ensure the sealing effect, the compression amount of the first sealing lip 11 is controlled between 4mm-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), so as to improve the scraping effect, provide the driver and passengers with a better field of vision, and ensure 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 sound 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 in the length direction. Through this design, the overall strength, stability and flexibility of the first water-cutting body 10 and the scraping structure 12 can be ensured, thereby ensuring the sealing effect and the scraping effect.

[0066] Furthermore, the first scraper and water-cutting body 120 is provided with a first end face 15 of an arc structure at one end close to the second scraper and water-cutting body 121, and correspondingly, the second scraper and water-cutting body 121 is provided with a second end face 16 adapted to the arc of the first end face 15 at the corresponding side. The advantage of this design is that the physical interference of the second scraper and water-cutting body 121 when rotating relative to the first scraper and water-cutting body 120 can be reduced by the cooperation of the first end face 15 with an outward convex design and the second end face 16 with an inward concave design, and the stable effect of the movement can be ensured.

[0067] Furthermore, the driving device 13 comprises:

[0068] A first drive motor 131, wherein the 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 through a first transmission rod 133;

[0069] A second driving motor 132, wherein the second driving motor 132 is arranged on the first scraping and water cutting body 120, and the second driving motor 132 is used to drive the second scraping and water cutting body 121 to rotate relative to the first scraping and water cutting body 120;

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

[0071] Specifically, in the initial state, the first scraping and water-cutting body 120 and the second scraping and water-cutting body 121 are limitedly contacted with the upper end of the first water-cutting body 10; when in use, the first scraping and water-cutting body 120 and the second scraping and 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 and 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 scraping and water-cutting body 120 and the second scraping and water-cutting body 121 rotate from the initial position to the predetermined position at an angle of 0°-40°, thereby controlling the initial state and working state of the first scraping and water-cutting lip 124. Further, the advantage of this design is that the predetermined position in the working state can be pre-configured according to different vehicle models, thereby meeting the use requirements of different vehicle models.

[0073] In another embodiment, the outer water cut structure includes two sets of outer water cut components 1, which are installed together at the bottom of the door frame to completely cover the bottom of the door frame. Compared with using one set of outer water cut components 1, the advantage is that the surface water mist and dirt cleaning effect of the door glass 3 is better and the function is powerful. The disadvantage is that the number of parts is large, the installation process is relatively time-consuming, the cost is relatively high, and it is 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 washing system of the vehicle; wherein the spraying direction of the nozzle is always toward the outer surface of the door glass 3.

[0076] The vehicle further comprises 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 present application ensures the beautiful appearance of the door by hiding the external water-cutting structure on the upper part of the door sheet metal 2. In special weather conditions, it can also respond to external weather conditions and intelligently open the scraping structure 12 to remove water mist and dirt on the glass surface to ensure that the driver's line of sight is not disturbed, thereby ensuring safe driving behavior.

[0078] Furthermore, the control display module can be triggered by operating instructions or voice commands to enable the cleaning and decontamination function of the door glass 3 alone, that is, by spraying detergent with a nozzle, stubborn stains on the glass surface can be cleaned.

[0079] On the other hand, the present application provides a method for controlling an external water shear structure, comprising the following steps:

[0080] Obtaining target weather conditions outside the target vehicle; the target weather conditions at least include rainy days, snowy days, and foggy days;

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

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

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

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

[0085] Example

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

[0087] It can be understood that the present application can intelligently activate the cleaning function of the door glass surface under special weather conditions, thereby ensuring that the driver's vision is not affected and improving driving safety behavior.
