Description

Technical Field

[0001] The present application relates to the technical field of vehicles, and particularly to a door water cut component, a door, a vehicle, and a control method for a door. Background Art

[0002] The design of frameless doors abandons the fixed window frame structure of traditional doors, making the vehicle styling more streamlined and significantly enhancing the overall texture, which is deeply favored by consumers pursuing individuality and high-end experiences. As the core component to ensure the normal lifting function of the door glass, the frameless door glass lifter is crucial for maintaining the overall performance and usage quality of the frameless door, and its importance is self-evident.

[0003] To adapt to the limitation of no sheet metal window frame above the door sill line of the frameless vehicle, the glass lifter is pre-bent as a whole or partially. By changing the stress state of the glass during the lifting process, the functional requirements for the lifting of the frameless door glass are met, enabling the glass to better fit the vehicle body in the closed state, improving the sealing performance and sound insulation effect of the door, and ensuring the stability of the glass lifting to a certain extent.

[0004] Due to the pre-bending design of the glass, the compression amount of the inner water cut increases significantly. Especially when the door is in the open state, the excessive compression force generated by the pre-bending of the glass causes excessive extrusion with the inner water cut, resulting in a significant increase in the friction force between the glass and the water cut during the lifting process. This not only easily generates abnormal noises, affecting the usage quality of the vehicle and the comfortable experience of the passengers and drivers, but also accelerates the wear of the inner water cut, reducing its sealing performance and service life, and further causing potential problems such as increased interior noise and water leakage, seriously damaging the overall performance and reliability of the vehicle. In addition, with the passage of time and the increase in the vehicle's mileage, the excessive wear of the inner water cut may further exacerbate the problems of glass lifting jamming and abnormal noises, increasing the vehicle's maintenance cost and after-sales service burden, which is not conducive to the long-term development of automobile manufacturers and the maintenance of the brand image. Summary of the Invention

[0031] In addition, if these terms "first" and "second" appear, these terms are only used for descriptive purposes and should not be construed as indicating or implying relative importance or implicitly indicating the quantity of the indicated technical features. Thus, features defined with "first" and "second" may explicitly or implicitly include at least one of these features. In the description of the present application, if the term "plurality" appears, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise specifically defined.

If so, the terms "vertical", "horizontal", "up", "down", "left", "right" and similar expressions used in this application are only for the purpose of illustration and do not represent the only implementation.

[0035] In one embodiment of this application, a vehicle is provided, which can be a vehicle of any type and any drive form without limitation. The vehicle includes a door 10 as in any of the following embodiments, and also includes a vehicle body with an A-pillar. The A-pillar is a column on both sides of the front windshield 200 of the vehicle, located at the front of the vehicle and between the front windshield 200 and the front door 10. The door 10 is rotatably connected to the vehicle body, and the limiting component is located at one end of the inner water cut 120 away from the A-pillar, which is related to the extrusion degree of the inner water cut 120 at different positions after the glass 200 is pre-bent. In this embodiment, after the glass 200 is pre-bent, during the lifting process, the end of the inner water cut 120 away from the A-pillar is more severely extruded by the glass 200. Therefore, the limiting component 130 is located at the end of the inner water cut 120 away from the A-pillar, but this is not a limitation.

[0036] In some embodiments, the vehicle body further includes a B-pillar, which is spaced apart from the A-pillar. The B-pillar is located on the side of the vehicle, between the front door 10 and the rear door 10, and is a key component of the side structure of the vehicle body. At this time, the door 10 is rotatably connected between the A-pillar and the B-pillar, and the following stopper assembly 130 is located at one end of the inner water cut 120 close to the B-pillar.

[0037] See also Figure 1 , Figure 1 The schematic diagram of the structure of the vehicle door 10 in one embodiment of the present application is shown. The vehicle door 10 provided in one embodiment of the present application can be applied to the above-mentioned vehicle. The vehicle door 10 includes a vehicle door water-cut assembly 100 as described in any of the following embodiments, and also includes a liftable glass 200, wherein the glass 200 can be partially or entirely pre-bent, or can be a conventional glass 200, without limitation. Figure 1 As shown, the vehicle door 10 further includes an interior trim panel 300 and an exterior trim panel 400 . The exterior trim panel 400 is located on the outside of the glass 200 , and the interior trim panel 300 is located on the inside of the glass 200 . Both are used to beautify the vehicle door 10 .

[0038] like Figure 2 As shown, the following abutment portion 1321 is located on one side of the theoretical lifting path of the glass 200, wherein the theoretical lifting path refers to the lifting path of the glass 200 in theory without the action of the infinite position assembly 130. It should be noted that Figure 2 In the figure, the glass 200 in the actual lifting path (the lifting path after being interfered by the limit assembly 130) is indicated by a dotted line, and the glass 200 in the theoretical lifting path (the lifting path not interfered by the limit assembly 130) is indicated by a solid line. This is only for the convenience of explanation and is not intended to be limiting.

[0039] Combination Figure 3 As shown, Figure 3 The schematic diagram of the structure of the vehicle door water cutting assembly 100 in one embodiment of the present application is shown. One embodiment of the present application provides a vehicle door water cutting assembly 100, which includes a support plate 110, an inner water cutting 120 and a limit assembly 130. Exemplarily, in this embodiment, the support plate 110 is a sheet metal of the vehicle door 10.

[0040] like Figure 4 As shown, the inner water cutter 120 includes a main body 121 and a lip 122. The main body 121 is connected to the support plate 110. In this embodiment, the main body 121 is a bent structure, which is covered on the top of the support plate 110, but this is not limited to this. Figure 4 As shown, the lip portion 122 protrudes from the end surface of the main body portion 121 away from the support plate 110, as shown in FIG. Figure 1 and Figure 2As shown, the glass 200 is located on the side of the support plate 110 facing the lip portion 122. During the lifting and lowering process of the glass 200, the glass 200 will squeeze the lip portion 122 and drive the lip portion 122 to deform.

[0041] As Figure 1 and Figure 2 As shown, in the present embodiment, the door water cut assembly 100 further includes an outer water cut 140. During the lifting and lowering process of the glass 200, the outer water cut 140 and the inner water cut 120 are respectively located on both sides of the glass 200 and are in close contact with the glass 200, so as to achieve the effect of sealing and waterproofing.

[0042] As Figures 2 to 4 As shown, the limiting assembly 130 is connected to the support plate 110, and the limiting assembly 130 includes a driving member 131 and a movably arranged moving member 132. In the present embodiment, the moving member 132 can move along its own axis, but this is not a limitation. In other embodiments, the moving direction of the moving member 132 can also be other directions that form an angle with the lifting and lowering direction of the glass 200.

[0043] As Figure 2 and Figure 4 As shown, the moving member 132 includes an abutting portion 1321 that partially protrudes from the support plate 110. The abutting portion 1321 and the lip portion 122 are located on the same side of the support plate 110, and the maximum length of the abutting portion 1321 protruding from the support plate 110 is less than the length of the lip portion 122 protruding from the support plate 110 when no force is applied, so as to prevent the limiting assembly 130 from being larger than the length of the lip portion 122 and interfering with the sealing and waterproofing effect of the inner water cut 120. During the lifting and lowering process of the glass 200, the glass 200 first contacts the lip portion 122 of the inner water cut 120, and the maximum length of the abutting portion 1321 protruding from the support plate 110 is not less than the thickness of the main body portion 121, so that the abutting portion 1321 in the limiting assembly 130 plays a role of jacking up when the glass 200 over-presses the inner water cut 120, so as to support the glass 200, prevent the glass 200 from excessively squeezing the lip portion 122 of the inner water cut 120, and further reduce problems such as abnormal noise and wear caused by the squeezing of the glass 200 on the inner water cut 120, and achieve the improvement of the sound quality of the lifting of the glass 200.

[0044] Combined with Figure 5As shown, the driving member 131 is drivingly connected to the moving member 132 and is used to drive the moving member 132 to move along the axial direction of the moving member 132, so that the length of the abutting portion 1321 protruding from the support plate 110 is adjustable, so that the abutting portion 1321 can extend to the maximum length, and the maximum length is within the length range that the lip portion 122 protrudes from the support plate 110 without force but is greater than the thickness of the main body portion 121. It can abut against the glass 200 during the lifting and lowering of the glass 200, avoiding the over-extrusion of the glass 200 on the inner water cut 120. At the same time, the abutting portion 1321 can also be shortened to the minimum length. At this time, the length of the abutting portion 1321 protruding from the support plate 110 is less than or equal to the thickness of the main body portion 121. At this time, the abutting portion 1321 has no interaction force on the glass 200, which is applicable when the glass 200 is not in the lifting and lowering process or when the glass 200 is in the lifting and lowering process but there is no hidden danger of over-extrusion on the inner water cut 120, and it can avoid problems such as slight displacement of the glass 200 caused by the abutting portion 1321 continuously abutting against the glass 200 for a long time. It should be noted that the minimum length that the abutting portion 1321 can be shortened to can be flush with the support plate 110, protruding from the support plate 110 but with a small length, or recessed into the support plate 110, which is not limited. It can be understood that the length of the abutting portion 1321 protruding from the support plate 110 can also be adjusted between the maximum length and the minimum length. At this time, the change in the length of the abutting portion 1321 protruding from the support plate 110 affects the magnitude of the supporting force of the abutting portion 1321 on the glass 200, and further affects the magnitude of the interference of the abutting portion 1321 on the actual lifting and lowering path of the glass 200.

[0045] In one embodiment, the moving member 132 is made of polyoxymethylene resin material, which has excellent wear resistance and good self-lubricity, and can be applied to multiple liftings and lowerings of the glass 200, avoiding abnormal noises between the glass 200 and the limiting component 130.

[0046] As Figure 1 and Figure 3 As shown, in one embodiment, the limiting component 130 is located on one side in the extending direction of the inner water cut 120. In this embodiment, the extending direction of the inner water cut 120 is consistent with the front-rear direction of the vehicle. In this embodiment, in the front-rear direction, the limiting component 130 is located on the rear end side of the inner water cut 120, but it is not limited. The limiting component 130 can also be located on the front end side of the inner water cut 120.

[0047] In one embodiment, the distance that the abutting portion 1321 can move along its own axis is not greater than 6 mm, avoiding the over-long movable distance of the abutting portion 1321 in the axial direction of the moving member 132, which affects the sealing effect of the inner water cut 120 and the lifting and lowering of the glass 200.

[0048] As Figures 4 to 6As shown, in one embodiment, an avoidance groove 123 is recessed in the end face of one end of the inner water cut 120 close to the limit component 130, so as to prevent the inner water cut 120 from interfering with the installation of the limit component 130 and also prevent the inner water cut 120 from being too short to affect the sealing. In this embodiment, avoidance grooves 123 are respectively provided on the parts of the inner water cut 120 located on both sides of the support plate 110.

[0049] As Figure 2 , Figures 4 to 8 shown, in one embodiment, the limit component 130 includes a fixing member 133, the fixing member 133 is fixedly connected to the support plate 110, and the moving member 132 can move along the direction of its own axis and then be fastened to the fixing member 133 to adjust the length of the abutting portion 1321 protruding from the support plate 110.

[0050] As Figures 4 to 7 shown, in this embodiment, the support plate 110 includes a plate body 111 and a bracket 112. One end of the bracket 112 is connected to the plate body 111, and the other end extends towards the direction where the fixing member 133 is located and is spaced from the plate body 111. The free end of the bracket 112 and the plate body 111 are both connected to the fixing member 133, so that when the moving member 132 moves relative to the fixing member 133, the fixing member 133 is more stable.

[0051] As Figures 4 to 7 shown, in this embodiment, the fixing member 133 includes a column body 1331 and a first limit block 1332 protruding from the circumferential surface of the column body 1331. As Figure 7 shown, the support plate 110 is provided with a limit hole 113 adapted to the first limit block 1332, and the first limit block 1332 is partially inserted into the limit hole 113 to prevent the fixing member 133 from rotating with the moving member 132.

[0052] As Figures 4 to 8 shown, in this embodiment, the fixing member 133 further includes a second limit block 1333 protruding from the circumferential surface of the column body 1331. The second limit block 1333 and the first limit block 1332 are spaced apart in the axial direction of the column body 1331, and the bracket 112 is connected to the second limit block 1333 to make the fixing member 133 more firm.

[0053] As Figure 5As shown, in one embodiment, the limiting component 130 further includes a transmission member 134. The transmission member 134 is controlled by the driving member 131, and the transmission member 134 includes a transmission shaft 1341 that rotates with the driving member 131. An external thread is provided on the circumferential surface of the transmission shaft 1341. One end of the moving member 132 away from the abutting portion 1321 is recessed with a mounting hole 1322, and an internal thread adapted to the transmission shaft 1341 is provided on the hole wall of the mounting hole 1322. When the transmission shaft 1341 rotates, it drives the moving member 132 to move along the axial direction of the moving member 132. By controlling the rotation direction of the transmission shaft 1341, forward or reverse rotation, the elongation and shortening of the abutting portion 1321 are realized. In this embodiment, the transmission member 134 further includes a transmission gear set (not shown), and the driving member 131 may be a stepper motor, but this is not a limitation. In other embodiments, the moving member 132 itself may also be provided as a telescopic structure, for example, the moving member 132 is a telescopic rod.

[0054] In one embodiment, the end surface of the abutting portion 1321 away from the support plate 110 is an abutting surface 13211, and the connecting surface between the abutting surface 13211 and the circumferential surface of the abutting portion 1321 is an arc surface, so that the contact between the glass 200 and the limiting component 130 is smoother during the lifting process.

[0055] As Figure 9 and Figure 10 shown, in one embodiment, the vehicle door 10 further includes a first detection member 500. The first detection member 500 is used to detect whether the vehicle door 10 is in an open state or a closed state. As Figure 9 and Figure 10 shown, in this embodiment, the first detection member 500 is installed at one end of the vehicle door 10 close to the A-pillar. The driving member 131 is controlled by the first detection member 500 to adjust the length of the abutting portion 1321 protruding from the support plate 110 according to the state of the vehicle door 10 obtained by the first detection member 500.

[0056] When the first detection member 500 detects that the vehicle door 10 is in an open state, the driving member 131 drives the moving member 132 to move so that the abutting portion 1321 protrudes from the support plate 110. As Figure 1 and Figure 2 shown, the abutting portion 1321 abuts against the glass 200 during the lifting process of the glass 200 to interfere with the actual lifting path of the glass 200, so as to abut against the glass 200 during the lifting process of the glass 200 and avoid the glass 200 from excessively squeezing the inner water cut 120. It can be understood that the actual lifting path refers to the path along which the glass 200 is lifted under the action of the limiting component 130.

[0057] In this embodiment, the actual lifting path of the glass 200 is offset by 2 mm to 4 mm relative to the theoretical lifting path of the glass 200. Due to different vehicle models, or due to different materials or structures of the inner water cut 120 in the following door water cut assembly 100, the length of the limiting component 130 protruding from the main body portion 121 in the following inner water cut 120 does not necessarily have a linear relationship with the interference of the limiting component 130 on the lifting path of the glass 200. In practical applications, experimental comparisons can be made on the interference amount of the limiting component 130 on the lifting path of the glass 200 at different lengths of the limiting component 130 protruding from the support plate 110, and then the length of the abutting portion 1321 protruding from the support plate 110 corresponding to the interference amount of the limiting component 130 on the lifting path of the glass 200 being 2 mm to 4 mm can be selected.

[0058] When the first detection member 500 detects that the door 10 is in the closed state, the driving member 131 drives the moving member 132 to move so that the length of the abutting portion 1321 protruding from the support plate 110 is not greater than the thickness of the main body portion 121, or it can also be that the abutting portion 1321 does not protrude from the support plate 110, that is, the length of the abutting portion 1321 protruding from the support plate 110 can be zero, and the abutting portion 1321 has no interaction force on the glass 200. When the glass 200 is not in the lifting process or although the glass 200 is in the lifting process but there is no hidden danger of excessive extrusion on the inner water cut 120, problems such as slight displacement of the glass 200 caused by the abutting portion 1321 continuously abutting against the glass 200 for a long time can be avoided.

[0059] As Figure 9 and Figure 10 shown, in one embodiment, the door 10 further includes a second detection member 600. The second detection member 600 is used to detect whether the handle of the door 10 releases an unlocking signal. As Figure 10 shown, the second detection member 600 is located at the position of the handle of the door 10, and the driving member 131 is controlled by the second detection member 600 to adjust the length of the abutting portion 1321 protruding from the support plate 110 according to the state of the handle of the door 10 obtained by the second detection member 600.

[0060] When the second detection member 600 detects that the handle of the door 10 releases an unlocking signal, the driving member 131 drives the moving member 132 to move so that the abutting portion 1321 protrudes from the support plate 110. The abutting portion 1321 abuts against the glass 200 during the lifting process of the glass 200 to interfere with the actual lifting path of the glass 200. The actual lifting path of the glass 200 is offset by 2 mm to 4 mm relative to the theoretical lifting path of the glass 200, so as to abut against the glass 200 during the lifting process of the glass 200 and avoid the effect of excessive extrusion of the glass 200 on the inner water cut 120.

[0061] In this embodiment, as Figure 9 andFigure 10 As shown, the vehicle door 10 further includes a door lock switch 700. The driving member 131, the first detecting member 500, the second detecting member 600, and the door lock switch 700 are all connected by wires to achieve signal transmission, so as to realize that the driving member 131 and the door lock switch 700 are controlled by the first detecting member 500 and / or the second detecting member 600, and realize adjusting the length of the abutting portion 1321 protruding from the support plate 110 through the signals of the first detecting member 500 and / or the second detecting member 600, and further adjusting the supporting strength of the limiting assembly 130 on the glass 200.

[0062] In one embodiment of the present application, a control method for a vehicle door 10 is further provided, which is applied to the vehicle door 10 in any of the above embodiments. The control method for the vehicle door 10 includes the following steps:

[0063] S10: Detect and determine whether the vehicle door 10 is in an open state or a closed state, so as to adjust the length of the abutting portion 1321 protruding from the support plate 110 according to the state of the vehicle door 10.

[0064] S20: If the vehicle door 10 is in an open state, control the driving member 131 to drive the moving member 132 to move until the abutting portion 1321 protrudes from the support plate 110 and abuts against the glass 200 to interfere with the actual descending path of the glass 200, so as to abut against the glass 200 during the lifting and lowering process of the glass 200 and avoid the effect of the glass 200 over-extruding the inner water cut 120.

[0065] S30: If the vehicle door 10 is in a closed state, control the driving member 131 to drive the moving member 132 to move so that the length of the abutting portion 1321 protruding from the support plate 110 is not greater than the thickness of the main body portion 121, and the abutting portion 1321 has no mutual acting force on the glass 200. When the glass 200 is not in the lifting and lowering process or there is no hidden danger of over-extruding the inner water cut 120 during the lifting and lowering process of the glass 200, it can avoid problems such as slight displacement of the glass 200 caused by the abutting portion 1321 continuously abutting against the glass 200 for a long time.

[0066] In one embodiment of the present application, a control method for a vehicle door 10 is further provided, which is applied to the vehicle door 10 in any of the above embodiments. The control method for the vehicle door 10 includes the following steps:

[0067] S10: Detect whether the handle of the vehicle door 10 releases an unlocking signal, so as to adjust the length of the abutting portion 1321 protruding from the support plate 110 according to the state of the handle of the vehicle door 10.

[0068] S20: If so, control the glass 200 of the vehicle door 10 to descend. During the descent of the glass 200, control the driving member 131 to drive the moving member 132 to move until the abutting portion 1321 protrudes from the support plate 110 and abuts against the glass 200 to interfere with the actual descent path of the glass 200, so as to abut against the glass 200 during the lifting and lowering of the glass 200, and avoid the glass 200 from excessively squeezing the inner water cut 120.

[0069] S30: Control the vehicle door 10 to unlock. Thus, during the opening of the vehicle door 10, the inner side of the glass 200 is limited by the abutting portion 1321, so as to prevent the glass 200 from shaking during the opening of the vehicle door 10.

[0070] In the vehicle door water cut assembly 100 provided in the above solution, by providing a limiting component 130 on one side of the inner water cut 120, and through the abutting portion 1321 protruding from the support plate 110 in the limiting component 130, during the lifting and lowering of the glass 200, the glass 200 first contacts the lip portion 122 of the inner water cut 120. The abutting portion 1321 plays a role of jacking up when the glass 200 overpresses the inner water cut 120, so as to support the glass 200 and avoid the glass 200 from excessively squeezing the lip portion 122 of the inner water cut 120. Furthermore, problems such as abnormal noise and wear caused by the squeezing of the glass 200 on the inner water cut 120 during lifting and lowering are reduced, and the sound quality of the glass 200 during lifting and lowering is improved. Also, the length of the abutting portion 1321 protruding from the support plate 110 can be adjusted under the action of the driving member 131, so that the length of the abutting portion 1321 protruding from the support plate 110 can be automatically adjusted according to the state of the vehicle door 10 or user needs, improving the adjustment flexibility of the support strength of the limiting component 130 for the glass 200, being applicable to diverse usage scenarios, and realizing the function of preventing the glass 200 from shaking when opening the door.
