[0025] As Figure 1 shown, in combination Figures 2-3 , the utility model first embodiment discloses the water cutting structure of car window glass, it includes inner water cutting 1, outer water cutting 2, transmission mechanism 3 and drive mechanism 4.

[0026] The inner water cutting 1 and the outer water cutting 2 are respectively arranged on the inner side and the outer side of the vehicle window glass S, and are in an initial state of clamping the glass together, so that the lips V are in contact with the surface of the glass to realize sealing and wiping. When it is necessary to reduce the lifting resistance of the glass or avoid unnecessary clamping, the inner water cutting 1 and the outer water cutting 2 are synchronously moved to a rest position away from the glass under the driving, so that the lips V are separated from the surface of the glass and the continuous stress is eliminated. The double-sided corresponding arrangement of the inner water cutting 1 and the outer water cutting 2 ensures symmetrical support and sealing of the glass, and provides a structural basis for synchronous movement.

[0027] The transmission mechanism 3 is a key connecting component for realizing synchronous movement of the inner water cutting 1 and the outer water cutting 2, and is connected with the inner water cutting 1 and the outer water cutting 2 respectively. The transmission mechanism 3 can distribute the power of a single driving source to the two water cuttings, so that the relative positions of the two water cuttings are stable during movement, and clamping misalignment or sealing failure caused by asynchronous movement is avoided.

[0028] The driving mechanism 4 drives the inner water cutting 1 and the outer water cutting 2 to move synchronously through the transmission mechanism 3, so that the two water cuttings are switched between the clamping working position and the rest position away from the glass. This function is realized by controlling the running state of the driving mechanism 4: when the water cutting is needed to work, the driving mechanism 4 drives the inner water cutting 1 and the outer water cutting 2 to move towards the glass through the transmission mechanism 3, until the lips V are in contact with the surface of the glass and clamping is formed; when the water cutting is needed to rest, the driving mechanism 4 drives the two water cuttings to move away from the glass in the reverse direction through the transmission mechanism 3, until the two water cuttings are completely separated from the glass. The switching process ensures that the relative positions of the inner water cutting 1 and the outer water cutting 2 are unchanged through synchronous movement, and the structural integrity and sealing reliability are maintained.

[0029] The vehicle window glass water cutting structure disclosed in the embodiment realizes active conversion of the water cutting between the clamping working position and the rest position away from the glass, through the double-sided corresponding arrangement of the inner water cutting 1 and the outer water cutting 2, the synchronous connection of the transmission mechanism 3 and the position switching control of the driving mechanism 4. Compared with the traditional water cutting with continuous clamping, the lips V of the water cutting structure only contact the glass when needed, which greatly reduces the long-term stress of the material and delays fatigue aging. At the same time, in the rest position away from the glass, invalid wear in the non-working state is avoided, the stability of the pressing force of the lips V on the glass is maintained, the wiping effect and the sealing performance are ensured to be durable and reliable, and the clarity of the driving vision and the safety in use are effectively improved.

[0030] The embodiment shows a structure of the transmission mechanism 3. Specifically, the transmission mechanism 3 includes a first fixed rod 31, a second fixed rod 32, a first swing frame 33, a second swing frame 34 and a connecting rod 35.

[0031] The first fixed rod 31 is used for fixed connection with the inner side of the outer door panel 5, serving as the basic fulcrum of the outer water cut 2 movement; the second fixed rod 32 is used for fixed connection with the inner side of the inner door panel 6, serving as the basic fulcrum of the inner water cut 1 movement. The two fixed rods provide a stable installation basis for the entire transmission system.

[0032] One end of the first swing frame 33 is rotatably connected to the first fixed rod 31, forming a rotating pair, so that the swing frame can swing around the fixed rod. The other end of the first swing frame 33 is directly connected to the outer water cut 2, converting the swing motion into linear or arc motion of the outer water cut 2. This connection ensures the accuracy of the movement trajectory of the outer water cut 2.

[0033] The second swing frame 34 is arranged on the inner side according to the same principle, one end of which is rotatably connected to the second fixed rod 32, and the other end is connected to the inner water cut 1. The swing frames on the inner and outer sides are connected through the connecting rod 35, and the two ends of the connecting rod 35 are fixedly connected to the first swing frame 33 and the second swing frame 34 respectively.

[0034] The driving mechanism 4 acts on the first swing frame 33 to drive it to swing around the first fixed rod 31. When the first swing frame 33 starts to move, the power is transmitted to the second swing frame 34 through the connecting rod 35, forcing the second swing frame 34 to produce synchronous swing around the second fixed rod 32. This transmission design ensures that the two swing frames always maintain a coordinated motion state, realizing the synchronous action of approaching or separating from each other.

[0035] The transmission mechanism 3 converts a single rotary input into symmetrical motion of the inner and outer water cuts 2, and through the stable fulcrum provided by the fixed rod and the lever action of the swing frame, it realizes effective force transmission and accurate control of the motion direction. The connecting rod 35 plays a key role in synchronous coordination in this process, preventing the clamping failure caused by the asynchronous motion of the inner and outer water cuts 2.

[0036] This transmission layout of the embodiment makes full use of the limited space between the inner and outer door panels, and realizes complex functional requirements through a simple linkage structure. The rotary connection between the components effectively reduces the movement resistance, improves the response speed and service life of the system.

[0037] In some embodiments, the first fixed rod 31 and the second fixed rod 32 are arranged in parallel with a horizontal interval. This arrangement provides a stable symmetrical basis for the movement of the inner and outer water cuts 2, ensuring the parallelism of the movement trajectories on both sides. The spatial relationship between the two fixed rods directly determines the movement stability and reliability of the entire transmission system.

[0038] The first swing frame 33 comprises a first mounting rod 331 and first swing arms 332 connected to both ends thereof respectively. The first mounting rod 331 is arranged in a horizontal direction and is fixedly connected to the outer water cut 2 to directly transmit the movement to the outer water cut 2. The two first swing arms 332 are vertically connected to both ends of the first mounting rod 331 respectively to form a U-shaped frame structure. The distal end of each first swing arm 332 is hingedly connected to the first fixed rod 31, so that the entire first swing frame 33 can rotate and swing around the first fixed rod 31 as the axis.

[0039] The second swing frame 34 adopts a similar frame structure and comprises a second mounting rod 341 and double second swing arms 342. The second mounting rod 341 is fixedly connected to the inner water cut 1 and is responsible for driving the inner water cut 1 to move. The second swing arms 342 have a special connection mode, in which the middle part thereof is hingedly connected to the second fixed rod 32, so that the second swing arms 342 become a lever structure with the hinged point as the fulcrum.

[0040] The connecting rod 35, as a key transmission element, is hingedly connected to the middle part of a certain first swing arm 332 at one end and is hingedly connected to the distal end of the corresponding second swing arm 342 (i.e., the end away from the second mounting rod 341) at the other end. This hinged connection mode ensures the flexibility of power transmission and reduces the constraint force in the movement process.

[0041] When the driving mechanism 4 drives the first swing frame 33 to swing around the first fixed rod 31, the connecting rod 35 transmits the movement to the distal end of the second swing arm 342. Since the second swing arm 342 adopts a lever design with a middle fulcrum, the movement input at the distal end will be converted into an output of amplified displacement at the second mounting rod 341, thereby driving the inner water cut 1 to complete the predetermined movement. The symmetrical arrangement of the two swing arms ensures the stability of the movement process.

[0042] The present embodiment realizes the accurate synchronous movement of the inner and outer water cuts 2 through reasonable layout of the rod system and connection mode. The application of hinged connection effectively reduces the frictional resistance of the movement pair and improves the transmission efficiency. The use of the lever principle enables the movement stroke to meet the functional requirements in a limited space while ensuring the reliability of force transmission. The entire transmission system has a compact structure and coordinated movement, thereby providing stable mechanical support for the position switching of the water cut.

[0043] In some embodiments, the installation position of the second fixed rod 32 in the horizontal direction is higher than that of the first fixed rod 31, and the two form a height difference in the vertical direction. This upper and lower arrangement makes full use of the three-dimensional space between the inner and outer panels of the vehicle door, so that the layout of the transmission mechanism 3 is more compact and reasonable.

[0044] Specifically, the position difference of the fixed rods makes the movement trajectory of the inner and outer water cuts 2 better match the tilt angle of the window glass. When the window glass is usually installed at a certain angle, the design of the second fixed rod 32 being located on the upper side makes the movement direction of the inner water cut 1 closer to the actual orientation of the glass, reducing unnecessary movement components.

[0045] The first swing frame 33 and the second swing frame 34 are hinged on fixed rods of different heights, and such staggered layout provides a more optimal transmission angle for the connecting rod 35. When transmitting movement, the connecting rod 35 can drive the second swing arm 342 to move at a smoother angle, reducing the risk of dead points and jamming during movement.

[0046] The upper position of the second fixed rod 32 makes the leverage of the second swing arm 342 better. Since the second swing arm 342 adopts a central hinge design, the connection point of its distal end and the connecting rod 35 is located at a higher position, which enhances the efficiency of force transmission, enabling the inner water cut 1 to obtain sufficient compression force with smaller input force. In addition, the upper and lower arrangement of the fixed rods also optimizes the stress distribution of the entire transmission system. The torque borne by each rod during movement is more balanced, reducing the phenomenon of local stress concentration and improving the reliability and service life of the system.

[0047] In some embodiments, the output end of the driving mechanism 4 and the distal end of the first swing arm 332 adopt a fixed connection mode, ensuring the reliability and directness of power transmission. When the driving mechanism 4 operates, the rotational torque is transmitted to the first swing arm 332 without loss, which in turn drives the entire first swing frame 33 to rotate around the axis of the first fixed rod 31. Such rigid connection avoids the gap errors that may occur when using intermediate transmission links, improving the accuracy of movement control.

[0048] In specific implementations, the driving connection point can be selected at the distal end of the single-sided first swing arm 332 or the double-sided first swing arm 332.

[0049] When a single-sided driving configuration is adopted, the driving mechanism 4 establishes a fixed connection with the distal end of any one of the first swing arms 332. Since the first swing frame 33 forms a rigid frame structure through the first mounting rod 331, the torque of the single-sided driving can be effectively transmitted to the swing arm on the other side, ensuring the synchronous movement of the entire swing frame. Such configuration saves the number of driving elements, reduces the manufacturing cost, and at the same time meets the basic functional requirements.

[0050] In application scenarios requiring greater driving force or higher reliability, a double-sided driving configuration can be adopted. That is, driving mechanisms 4 are arranged at the distal ends of the first swing arms 332 on the left and right sides, forming a symmetrical driving layout. Double-sided driving not only improves the output capacity of the system, but also creates a redundant backup, so that when a single-sided driving fails, the other side can still maintain the basic operation of the system.

[0051] In some embodiments, the driving mechanism 4 is a reduction motor. The reduction motor converts the high-speed rotating motion of the motor into a low-speed, high-torque output through an internal gear mechanism, which is very suitable for driving the water cutting structure to complete the clamping and separating actions.

[0052] In some embodiments, the inner water cutting 1 and the outer water cutting 2 have consistent structures, both of which include an elastic bubble tube P extending along the length direction, which serves as the main support structure of the water cutting and is made of elastic materials such as EPDM, TPV, or PVC. The inside of the elastic bubble tube P can be designed in a hollow form, so that it can deform elastically when subjected to extrusion and return to its original state after the external force is removed. This feature provides a stable support basis for the lip V.

[0053] At the top of the elastic bubble tube P, there is a continuous and inwardly inclined lip V. The lip V is also made of elastic material, which ensures that when the water cutting is in the fitted working position, the lip V can be in contact with the surface of the window glass at a suitable angle. The lip V extends along the entire length of the top of the bubble tube, forming a complete sealing and wiping edge.

[0054] In this embodiment, the elastic bubble tube P and the lip V are manufactured by an integrated molding process, ensuring that the connection between them is firm and has good sealing performance. The main function of the bubble tube is to provide support stiffness and elastic recovery force, while the lip V is directly responsible for the contact sealing and wiping action with the glass surface. The elastic deformation capability of the bubble tube allows the lip V to adapt to the slight unevenness of the glass surface, maintaining the uniformity of the contact.

[0055] When the water cutting moves to the fitted working position under the action of the driving mechanism 4, the inwardly inclined lip V first comes into contact with the glass surface. As the water cutting continues to move, the lip V deforms elastically, generating a normal pressure directed towards the glass surface. This pressure enables the lip V to effectively wipe off the water film and contaminants on the glass surface, while also achieving the sealing function. In the avoidance rest position, the lip V is completely separated from the glass surface, at which time the lip V is in a free state and does not bear any stress. This intermittent working mode significantly reduces the stress fatigue of the lip V material and avoids the aging problem of traditional water cutting due to long-term compression.

[0056] On the basis of the water cutting structure of the vehicle window glass, this embodiment further integrates the line-of-sight shielding detection and linkage decontamination function. By identifying the shielding state of rainwater, stains, and other contaminants on the vehicle window glass, the vehicle window is actively controlled to be lowered and the water cutting inner lip V is linked to perform decontamination, restoring the clarity of the field of view.

[0057] The detection device is responsible for identifying the state of visual obstruction, focusing on monitoring whether there are rainwater, mud stains, dust and other pollutants on the surface of the window glass that can obstruct the view. The device can use a multi-modal sensing scheme, for example, an optical camera captures images of the glass surface, and analyzes the area and distribution of stains through image recognition algorithms; or combines an infrared humidity sensor to detect the presence of water film, and a capacitive sensor to sense the change in surface dielectric constant caused by stains. The detection device collects glass state data in real time and transmits the judgment results such as "no obstruction", "slight obstruction" and "severe obstruction" to the control module.

[0058] The control module acts as the decision center. After receiving the obstruction signal from the detection device, it determines whether to start the decontamination process based on the pre-set threshold. When the obstruction level is detected to affect the driver's view (e.g., the stain coverage area exceeds 10% of the visible area of the glass), the control module sends a lowering command to the window lifting motor and a linkage control signal to the driving mechanism 4 of the water cutting structure, causing the inner water cutting 1 lip edge V to be synchronized with the glass during the window lowering process.

[0059] The driving mechanism 4 and the transmission mechanism 3 control the movement of the inner water cutting 1 while executing the window lowering. The inner water cutting 1 is connected to the driving mechanism 4 through the transmission mechanism 3. When the window starts to lower, the driving mechanism 4 drives the inner water cutting 1 to move towards the glass through the transmission mechanism 3, so that the top lip edge V of the elastic bubble tube P of the inner water cutting 1 contacts the glass surface. At this time, the control module maintains the normal pressure of the lip edge V on the glass by adjusting the output force of the driving mechanism 4 - using the deformation feedback of the elastic bubble tube P or the pressure sensor signal to dynamically adjust the torque of the driving mechanism 4, avoiding excessive pressure damaging the glass or insufficient decontamination.

[0060] During the entire process of window lowering and rising, the inner lip edge V maintains the state of being in contact with the glass. When the window is lowered, the lip edge V scrapes off the rainwater and stains on the outside of the glass; when the window is raised, it continues to clean the remaining contaminants, and the reciprocating motion enhances the decontamination effect. The elastic deformation capability of the elastic bubble tube P enables the lip edge V to adapt to the slight undulations of the glass surface, ensuring uniform pressure distribution and improving the scraping efficiency.

[0061] When the detection device confirms that the glass surface stains are removed and the view is unobstructed (e.g., image recognition shows that the cleanliness meets the standard), the control module sends a stop command to the driving mechanism 4, and the inner water cutting 1 moves away from the glass under the drive of the transmission mechanism 3, the lip edge V separates from the glass surface, and returns to the avoidance rest position. The window lifting motor stops synchronously, and the window stays at the target position.

[0062] The embodiment realizes the active response of the shielding problem by detecting the line-of-sight shielding state in real time through the detection device, and controlling the linkage of the window lifting and the water cutting action, and scraping the glass with the constant pressure of the inner lip V in the process of the window movement.

[0063] The utility model discloses still a kind of vehicle door, refer to attached Figure 4 And 5 As shown in the drawings, including vehicle door outer plate 5, vehicle door inner plate 6 and the water cutting structure of the window glass of the first aspect described;Wherein, the water cutting structure of the window glass is set between the vehicle door outer plate 5 and vehicle door inner plate 6. Specifically, the fixed arrangement of water cutting structure in vehicle door is fixedly connected by first fixed rod 31 and the inner side of vehicle door outer plate 5, and second fixed rod 32 and the inner side of vehicle door inner plate 6. Driving mechanism 4 can be fixedly installed with the inner side of vehicle door outer plate 5, and vehicle door outer plate 5 and vehicle door inner plate 6 form the lifting channel of window glass.

[0064] The vehicle door realizes the improvement of traditional fixed water cutting by integrating switchable water cutting structure. When the water cutting is in the adhering working position, the lip V of the inner and outer water cutting 2 clamps the glass, and performs sealing and scraping functions. When switched to the avoidance rest position, the lip V is separated from the glass, and the long-term clamping stress is released. This active switching mechanism fundamentally reduces the fatigue aging of the water cutting material, ensures the stable pressing force, and improves the scraping effect and sealing performance.
