Description

Technical Field

[0001] This application belongs to the field of vehicle parts technology, specifically relating to a car door and a vehicle. Background Technology

[0002] In the field of vehicle manufacturing, the door water cutter is installed on the lower edge of the window and is a key component located between the window glass and the door frame. It is mainly used for waterproofing, noise reduction, air diversion and aesthetics. For example, when the door water cutter and the door frame fit well, it can improve the door's sealing performance, thereby preventing water leakage and avoiding moisture damage to the window glass lifting motor, wiring harness and other components inside the door. Door water cutters typically include inner and outer water cutters. The inner water cutter is installed on the inside of the door frame and mainly serves a sealing function to prevent rainwater from seeping into the vehicle. The outer water cutter is installed on the outside of the door frame and is used to cut off adhering substances such as water droplets, water mist, and dust from the surface of the window glass during the raising and lowering of the window glass.

[0003] In practical applications, the two ends of the outer water cutter that are facing away from each other tend to lift up relative to the door frame, which reduces the fitting accuracy between the outer water cutter and the door frame, thus affecting the door's sealing performance and appearance clearance. Utility Model Content

[0004] The purpose of this application is to provide a car door and vehicle that can solve the problem in the related art that the two opposite ends of the outer waterline of the car door are prone to warping relative to the car door frame.

[0005] In a first aspect, embodiments of this application provide a vehicle door, including a door frame and an outer waterline, wherein the door frame is provided with a window, and the outer waterline is disposed at the lower edge of the window. The door frame includes an outer door panel and a reinforcing plate. The outer water cutter has a snap-fit ​​groove, which engages with the outer door panel and the reinforcing plate. The reinforcing plate has at least two clearance openings, including a first clearance opening and a second clearance opening spaced apart. The first clearance opening is located at one end of the reinforcing plate near the first end of the outer water cutter, and the second clearance opening is located at one end of the reinforcing plate near the second end of the outer water cutter.

[0006] In this embodiment, a first clearance opening is provided at one end of the reinforcing plate near the first end of the outer water-cutting edge, and a second clearance opening is provided at one end of the reinforcing plate near the second end of the outer water-cutting edge. The two opposing ends of the outer water-cutting edge can then be positioned and engaged with the first and second clearance openings respectively in the direction extending from the bottom to the top of the door via a first limiting protrusion on the inner wall of the snap-fit ​​groove. This prevents the opposing ends of the outer water-cutting edge from warping up, improving the fit accuracy between the outer water-cutting edge and the door frame, thereby improving the door's sealing performance and reducing the external gap of the door, thus reducing wind noise and wind resistance during vehicle operation. Therefore, this application can solve the problem in related technologies where the opposing ends of the outer water-cutting edge of the door are prone to warping relative to the door frame. In addition, in the above embodiments, when the outer door is deformed by external force, the two ends of the outer water cutter are respectively engaged with the first clearance opening and the second clearance opening in the direction extending from the bottom of the door to the top of the door through the first limiting protrusion. This helps to improve the snap-fit ​​between the two ends of the outer water cutter and the door frame, thereby preventing the outer water cutter from loosening.

[0007] Optionally, the outer door panel includes a connected outer panel body and an edging structure. The edging structure and the outer panel body are disposed opposite to each other in the direction extending outward from the inner side of the door to cover a portion of the first edge of the reinforcing plate. The outer water cutter engages with the outer panel body and the edging structure through the snap-fit ​​groove. The clearance openings are arranged sequentially at intervals along the first direction, and the clearance openings and the edging structure are spaced apart in the height direction of the door. Wherein, the first direction is the direction in which the connecting end of the car door extends toward the handle of the car door.

[0008] Optionally, the edging structure includes a first plate segment, a second plate segment, and a third plate segment spaced apart in the first direction. The lengths of the first plate segment and the third plate segment are both less than the length of the second plate segment.

At least a portion of the first limiting protrusion is located within the clearance opening, and the first limiting protrusion can be locked in place with the inner wall of the clearance opening in the second direction. The reinforcing plate is also provided with a boss structure corresponding to each of the avoidance openings. Each boss structure protrudes towards the inside of the door. In the height direction of the door, the boss structure is connected between the avoidance opening and the first edge. The boss structure forms the first inner wall of the avoidance opening. The first limiting protrusion can be limited to cooperate with the first inner wall in the second direction.

[0011] Optionally, each of the clearance openings is a strip structure, and each of the clearance openings extends along the first direction; and / or, In the first direction, the size of each of the clearance openings is larger than the size of each of the boss structures. Optionally, the direction in which the bottom of the door extends towards the top of the door is the second direction.

The first limiting protrusion can be engaged with the inner wall of the clearance opening in the second direction for upper limit engagement, and the second limiting protrusion can be engaged with the edging structure in the second direction for upper limit engagement. The at least two clearance openings also include a third clearance opening, which is located between the first clearance opening and the second clearance opening. When the door is in the first state, there is a first gap between the first limiting protrusion and the first inner sidewall of the third clearance opening, and there is a second gap between the second limiting protrusion and the edging structure.

Detailed Implementation

[0015] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0016] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0017] The following detailed description of the vehicle door and vehicle provided in this application embodiment, with reference to the accompanying drawings, through specific embodiments and application scenarios, will be provided in detail.

[0018] Please refer to Figures 1 to 7 As shown in the embodiment of this application, a car door is provided. Optionally, the car door can be the front door of the vehicle or the rear door of the vehicle. This embodiment of the application does not make specific limitations on this.

[0019] The vehicle door includes a door frame 100 and an outer water cutter 200. The door frame 100 has a window 110. Optionally, the door also includes a window glass, which is dynamically adjustable in the window 110 to close or open the window 110. The outer water cutter 200 is located at the lower edge of the window 110. In the direction extending from the connecting end 300 of the door towards the door handle 400, the outer water cutter 200 has a first end and a second end facing away from each other. Optionally, the outer water cutter 200 is located on the outside of the door frame 100 and is used to cut off adhering substances, such as water droplets, water mist, and dust, from the surface of the window glass during the raising and lowering of the window glass, thereby improving the clarity of the window glass.

[0020] The door frame 100 includes an outer door panel 120 and a reinforcing plate 130. An outer water cutter 200 has a snap-fit ​​groove 210, which engages with the outer door panel 120 and the reinforcing plate 130, thus creating a snap-fit ​​connection between the outer water cutter 200 and the door frame 100. Optionally, when the outer water cutter 200 and the door frame 100 have a good snap-fit ​​connection, this not only improves the door's sealing performance, preventing water leakage and avoiding moisture damage to internal components such as the window regulator motor and wiring harness; but also, the specific cross-sectional shape of the outer water cutter 200 (such as a streamlined lip) can guide airflow smoothly, thereby reducing the vehicle's drag coefficient (directly affecting fuel consumption and high-speed stability).

[0021] Since the outer water cutter 200 is an arc-shaped structure with a certain curvature, it can protrude along the height direction of the door and the outer side of the door. Usually, the curvature is small and difficult to identify with the naked eye. It can be measured by measuring tools. In practical applications, the two opposite ends of the arc-shaped outer water cutter 200 are prone to warping relative to the door frame 100. Based on this, the reinforcing plate 130 is provided with at least two clearance openings 131. Optionally, the inner wall of the snap-fit ​​groove 210 is provided with a first limiting protrusion 220 corresponding to each clearance opening 131. At least a part of the first limiting protrusion 220 is located inside the clearance opening 131. The first limiting protrusion 220 can be locked in place with the inner wall of the clearance opening 131 in the direction extending from the bottom to the top of the door. At least two clearance openings 131 include a first clearance opening 131a and a second clearance opening 131b spaced apart. The first clearance opening 131a is located at one end of the reinforcing plate 130 near the first end of the outer water cutter 200. Specifically, the first end of the outer water cutter 200 can be one end of the outer water cutter 200 near the connecting end 300 of the door. The second clearance opening 131b is located at one end of the reinforcing plate 130 near the second end of the outer water cutter 200. Specifically, the second end of the outer water cutter 200 can be one end of the outer water cutter 200 near the handle 400 of the door.

[0022] In this embodiment, a first clearance opening 131a is provided at one end of the reinforcing plate 130 near the first end of the outer water cutter 200, and a second clearance opening 131b is provided at one end of the reinforcing plate 130 near the second end of the outer water cutter 200. At this time, the two opposing ends of the outer water cutter 200 can be respectively positioned and engaged with the first clearance opening 131a and the second clearance opening 131b in the direction extending from the bottom to the top of the door via the first limiting protrusion 220 on the inner wall of the snap-fit ​​groove 210. This prevents the opposing ends of the outer water cutter 200 from lifting up, thereby improving the fitting accuracy between the outer water cutter 200 and the door frame 100, improving the door's sealing performance, and reducing the external gap of the door, thus reducing wind noise and wind resistance during vehicle operation. Therefore, this application can solve the problem in related technologies where the opposing ends of the outer water cutter 200 of the door easily lift up relative to the door frame 100.

[0023] In addition, in the above embodiments, when the outer door is deformed by external force, the two opposite ends of the outer water cutter are respectively engaged with the first clearance opening and the second clearance opening in the direction extending from the bottom of the door to the top of the door through the first limiting protrusion. This helps to improve the snap-fit ​​firmness between the two opposite ends of the outer water cutter 200 and the door frame 100, thereby preventing the outer water cutter from loosening.

[0024] In one optional embodiment, the door frame 100 includes a door outer panel 120 and a reinforcing plate 130. The door outer panel 120 includes a connected outer panel body 121 and an edge-wrapping structure 122. The edge-wrapping structure 122 and the outer panel body 121 are arranged opposite to each other in the direction of extending from the inside to the outside of the door to wrap a portion of the first edge 132 of the reinforcing plate 130. The outer water cutter 200 is engaged with the outer panel body 121 and the edge-wrapping structure 122 through a snap-fit ​​groove 210. Each clearance opening 131 is arranged sequentially at intervals along a first direction (i.e., the X direction in the figure), and each clearance opening 131 and the edge-wrapping structure 122 are spaced apart in the height direction of the door. The first direction is the direction in which the connecting end 300 of the door extends toward the door handle 400.

[0025] In the above embodiments, by providing clearance openings 131 and edging structures 122 spaced apart along the height direction of the door on the reinforcing plate 130 and the outer door panel 120, when the door deforms due to external force (such as impact), the outer water cutter 200 engages with the outer panel body 121 and edging structure 122 through the snap-fit ​​groove 210, thereby preventing the outer water cutter 200 from moving relative to the door frame 100; and when the force on the outer water cutter 200 is large, once the outer water cutter 200 moves relative to the door frame 100, After a slight movement, the first limiting protrusion 220 of the outer water cutter 200 and the inner wall of the clearance opening 131 of the reinforcing plate 130 are engaged in a limiting fit in the direction extending from the bottom to the top of the door, thereby preventing the outer water cutter 200 from moving further relative to the door frame 100 and preventing the outer water cutter 200 from loosening. That is, this solution forms a multi-layered snap-fit ​​structure in the direction extending from the bottom to the top of the door and forms a certain lever arm to improve the snap-fit ​​firmness between the outer water cutter 200 and the door frame 100.

[0026] In an optional embodiment, the edging structure 122 includes a first plate segment 122a, a second plate segment 122b, and a third plate segment 122c spaced apart in a first direction. The lengths of the first plate segment 122a and the third plate segment 122c are both less than the length of the second plate segment 122b. The first plate segment 122a is located near the first end of the outer water cutter 200, and the third plate segment 122c is located near the second end of the outer water cutter 200.

[0027] The edge-wrapping structure 122 in the above scheme adopts a three-section setting. The outer water cutter 200 and the door frame 100 are connected by a partial snap-fit ​​method. A first plate segment 122a is set at the first end near the outer water cutter 200 to snap-fit ​​with the outer water cutter 200, and a third plate segment 122c is set at the second end near the outer water cutter 200 to snap-fit ​​with the outer water cutter 200. This further prevents the first and second ends of the outer water cutter 200 from lifting up, thereby improving the sealing performance of the door. In addition, the middle part of the outer water cutter 200 is snap-fitted with the outer panel body 121 and the second plate segment 122b to prevent the middle part of the outer water cutter 200 from arching up, thereby further improving the connection stability between the outer water cutter 200 and the door frame 100. Of course, the first plate segment 122a and the third plate segment 122c mentioned above may not be provided. In this case, the first limiting protrusion 220 can be limited by the inner wall of the avoidance opening 131 on the reinforcing plate 130 to prevent the first and second ends of the outer water cutter 200 from tilting up.

[0028] It should be noted that the outer water cutter 200 is connected to the door frame 100 through the three-section edge-wrapping structure 122 mentioned above. At this time, the part between the outer water cutter 200 and the door frame 100 that is not engaged can disperse the force on the outer water cutter 200. Even if there is a slight arch in this part, it is difficult to identify with the naked eye, and its impact on the appearance of the door can be basically ignored.

[0029] Optionally, the length of the first plate segment 122a and the length of the third plate segment 122c may not be equal, that is, the length of the first plate segment 122a may be greater than or less than the length of the third plate segment 122c; or, in other optional embodiments, the length of the first plate segment 122a is equal to the length of the third plate segment 122c. In the first direction, the first plate segment 122a and the third plate segment 122c are symmetrically arranged about the central axis of the second plate segment 122b, and the central axis of the second plate segment 122b coincides with the central axis of the outer water cutter 200. That is to say, the entire edging structure 122 is symmetrically arranged about the central axis of the outer water cutter 200. At this time, in the first direction, the clamping force between the outer water cutter 200 and the door frame 100 is more evenly distributed, which can further prevent either the first end or the second end of the outer water cutter 200 from lifting due to the small clamping force.

[0030] In another optional embodiment, at least two clearance openings 131 further include a third clearance opening 131d, which is located between the first clearance opening 131a and the second clearance opening 131b, and is located below the second plate segment 122b. In the first direction, the first clearance opening 131a is offset from the first plate segment 122a, and the first clearance opening 131a is located on the side of the first plate segment 122a away from the central axis of the outer water cutter 200. The second clearance opening 131b is offset from the third plate segment 122c, and the second clearance opening 131b is located on the side of the third plate segment 122c away from the central axis of the outer water cutter 200. In this design, in the first direction, the first clearance opening 131a is staggered from the first plate segment 122a, and the second clearance opening 131b is staggered from the third plate segment 122c. This avoids mutual interference caused by the excessive concentration of the interlocking structures in the height direction of the door. For example, the first plate segment 122a may interfere with the first limiting protrusion 220 located at the first clearance opening 131a, and / or the third plate segment 122c may interfere with the first limiting protrusion 220 located at the second clearance opening 131b. This improves the interlocking matching accuracy between the outer water cutter 200 and the door frame 100. And stability; and, in the first direction, the first clearance opening 131a is provided on the side of the first plate segment 122a away from the central axis of the outer water cutter 200, and the second clearance opening 131b is provided on the side of the third plate segment 122c away from the central axis of the outer water cutter 200. That is, the first clearance opening 131a and the second clearance opening 131b are respectively provided at the two opposite ends of the reinforcing plate 130 and located on the outside of the edge-wrapping structure 122, thereby further improving the snap-fit ​​firmness and stability between the outer water cutter 200 and the door frame 100, thereby reducing the risk of the outer water cutter 200 coming off under extreme working conditions.

[0031] Optionally, the length of the edging structure 122 is less than the length of the outer water-cutting 200. In the first direction, the two opposite ends of the outer plate body 121 are respectively provided with a first part 121a and a second part 121b protruding from the reinforcing plate 130. Optionally, the length of the first part 121a can be equal to the length of the second part 121b, where "equal" includes being completely equal and approximately equal. The first clearance opening 131a is located in the middle area between the first plate segment 122a and the first part 121a, and the second clearance opening 131b is located in the third plate segment 122a. The intermediate region between segment 122c and the second part 121b, namely the first clearance opening 131a, is located between the first boundary of the edging structure 122 and the first boundary of the door, and is centrally located. Similarly, the second clearance opening 131a is located between the second boundary of the edging structure 122 and the second boundary of the door, and is centrally located. This arrangement allows for a more uniform distribution of the engagement force between the outer water cutter 200 and the opposite ends of the door frame 100, thereby improving the engagement stability between the outer water cutter 200 and the door frame 100. Of course, the first clearance opening 131a can also be located near the first plate segment 122a or the first part 121a, and the second clearance opening 131b can also be located near the third plate segment 122c or the second part 121b. In an optional embodiment, the direction in which the bottom of the door extends towards the top of the door is the second direction (i.e., the Z direction in the figure). The inner wall of the snap-fit ​​groove 210 is provided with a first limiting protrusion 220 corresponding to each of the clearance openings 131. At least a portion of the first limiting protrusion 220 is located inside the clearance opening 131. The first limiting protrusion 220 can be locked in the second direction with the inner wall of the clearance opening 131, thereby improving the snap-fit ​​stability between the outer water cutter 200 and the door frame 100, so as to avoid the outer water cutter 200 from moving significantly relative to the door frame 100 and prevent the outer water cutter 200 from loosening. Furthermore, the one-to-one correspondence between each first limiting protrusion 220 and each clearance opening 131 can increase the contact area between the outer water cutter 200 and the reinforcing plate 130, thereby improving the stability of the fit between the two, while ensuring the structural strength and rigidity of the reinforcing plate 130.

[0032] Because the edge-wrapping structure 122 has a certain height, the distance between the reinforcing plate 130 and the first side wall of the locking groove 210 is relatively large, that is, the distance between the clearance opening 131 and the first side wall of the locking groove 210 is also relatively large. At this time, the height of the first limiting protrusion 220 needs to be set relatively large so that it can extend into the clearance opening 131 and cooperate with the inner wall of the clearance opening 131 for limiting. Based on this, optionally, the reinforcing plate 130 is also provided with a boss structure 133 corresponding to the clearance opening 131. Each boss structure 133 protrudes towards the inside of the door. In the height direction of the door, the boss structure 133 connects the clearance opening 131 and the first edge 132 to reduce the distance between the clearance opening 131 and the first side wall of the locking groove 210. At this time, the height of the first limiting protrusion 220 can be set relatively small so that the lever arm of the first limiting protrusion 220 is shorter. The boss structure 133 forms a first inner sidewall 131c that avoids the opening 131, and the first limiting protrusion 220 can be engaged with the first inner sidewall 131c in the second direction for upper limit cooperation.

[0033] In the above embodiments, since the lever arm of the first limiting protrusion 220 is relatively short, its stability when it is limited by the inner wall of the clearance opening 131 can be better. In addition, the boss structure 133 in this solution is equivalent to a reinforcing rib, which can improve the structural rigidity of the reinforcing plate 130. Of course, the boss structure 133 can also be omitted, in which case the clearance opening 131 and the first edge 132 are located in the same plane.

[0034] Optionally, the clearance opening 131 can be a triangular or square structure; or, in other optional embodiments, each clearance opening 131 is a strip structure, and each clearance opening 131 extends along the first direction. This not only facilitates the insertion of at least a portion of each first limiting protrusion 220 into each clearance opening 131, but also ensures the structural strength and rigidity of the reinforcing plate 130. Optionally, each clearance opening 131 can be a strip-shaped square hole structure. Of course, it can also be selected according to actual needs, and this application embodiment does not impose specific limitations on this.

[0035] And / or, in another alternative embodiment, in the first direction, the size of each clearance opening 131 is larger than the size of each boss structure 133, which facilitates at least a portion of each first limiting protrusion 220 being inserted into each clearance opening 131. Of course, in the first direction, the size of each clearance opening 131 may also be equal to or smaller than the size of each first limiting protrusion 220. In an optional embodiment, the direction in which the bottom of the door extends towards the top of the door is the second direction (i.e., the Z direction in the figure). The first sidewall of the snap-fit ​​groove 210 is provided with a first limiting protrusion 220 and a second limiting protrusion 260 arranged sequentially in the second direction. The first limiting protrusion 220 can be engaged with the inner wall of the clearance opening 131 in the second direction, and the second limiting protrusion 260 can be engaged with the edge-sealing structure 122 in the second direction. At least two clearance openings 131 also include a third clearance opening 131d, which is located between the first clearance opening 131a and the second clearance opening 131b. When the door is in the first state, i.e., when the window is fully open, the window glass is located inside the door frame 100. There is a first gap between the first limiting protrusion 220 and the first inner sidewall 131c of the third clearance opening 131d, and there is a second gap between the second limiting protrusion 260 and the edge-sealing structure 122. The width of the first gap is greater than the width of the second gap.

[0036] When the car door is deformed by external force, the second limiting protrusion 260 first engages with the edge-wrapping structure 122 in the second direction to prevent the outer water cutter 200 from moving further relative to the door frame 100. When the external force on the car door is large and the deformation is severe, the movement of the outer water cutter 200 relative to the door frame 100 is correspondingly larger. At this time, the second limiting protrusion 260 slips off from the edge-wrapping structure 122 due to the large force it receives, that is, the limiting between the second limiting protrusion 260 and the edge-wrapping structure 122 fails. Therefore, further... The first limiting protrusion 220 can abut against the inner wall of the third clearance opening 131d. At this time, the first limiting protrusion 220 and the inner wall of the third clearance opening 131d are engaged in a limiting fit in the second direction, thereby preventing the outer water cutter 200 from moving further relative to the door frame 100 and preventing the outer water cutter 200 from loosening. In other words, this solution sets a two-stage limiting structure to gradually limit the movement, thereby further improving the locking firmness between the outer water cutter 200 and the door frame 100 and preventing the outer water cutter 200 from loosening. Of course, the width of the first gap mentioned above can also be equal to the width of the second gap.

[0037] Optionally, the width of the first gap can be 0.95~1.05mm, and the width of the second gap can be 0.75~0.85mm; further optionally, the width of the first gap can be 0.1mm, and the width of the second gap can be 0.08mm. Of course, the width of the first gap and the second gap can also be selected according to actual needs, and the embodiments of this application do not impose specific limitations on this.

[0038] In another optional embodiment, the snap-fit ​​groove 210 has opposing first and second sidewalls in the direction extending inward from the outer side of the door. The first sidewall is close to the inner side of the door and is provided with a snap-fit ​​boss 230. The snap-fit ​​boss 230 has a first end and a second end facing away from each other in the height direction of the door. The second sidewall is provided with a first snap-fit ​​lip 240 and a second snap-fit ​​lip 250. Optionally, at least one of the first snap-fit ​​lip 240 and the second snap-fit ​​lip 250 can be opposite to the middle portion of the snap-fit ​​boss 230, or the first snap-fit ​​lip 240 is opposite to the first end of the snap-fit ​​boss 230, and the second snap-fit ​​lip 250 is opposite to the second end of the snap-fit ​​boss 230. Both the first snap-fit ​​lip 240 and the second snap-fit ​​lip 250 cooperate with the outer panel body 121, that is, the first snap-fit ​​lip 240 and the second snap-fit ​​lip 250... The snap-fit ​​lips 250 make line contact or surface contact with the outer panel body 121 respectively. The snap-fit ​​boss 230 cooperates with the edging structure 122, and the two opposite sides are fitted together. That is, the snap-fit ​​boss 230 and the edging structure 122 make surface contact. At this time, the contact area between the first snap-fit ​​lip 240 and the outer panel body 121 and the contact area between the second snap-fit ​​lip 250 and the outer panel body 121 are smaller than the contact area between the snap-fit ​​boss 230 and the edging structure 122. The three structures cooperate with each other to snap-fit. The forces exerted by the first snap-fit ​​lip 240 and the second snap-fit ​​lip 250 on the outer panel body 121 are relatively dispersed. This can prevent the outer water cutter 200 from flipping due to excessive force concentration, thereby improving the snap-fit ​​stability and firmness between the outer water cutter 200 and the door frame 100.

The vehicle door is hinged to the body to facilitate closing or opening the vehicle's cabin.
