Detailed Description

Further features and advantages of the present invention will become apparent from the following description, which proceeds with reference to the accompanying drawings. Exemplary embodiments of the invention are illustrated in the accompanying drawings, and the various drawings are not necessarily drawn to scale. This invention may, however, be embodied in many different forms and should not be construed as necessarily limited to the exemplary embodiments set forth herein. Rather, these exemplary embodiments are provided only to illustrate the present invention and to convey the spirit and substance of the invention to those skilled in the art.

A window seal assembly and a vehicle door including the window seal assembly according to embodiments of the present invention are described below with reference to the accompanying drawings. In the following description, "front" (as indicated by arrow F) is used to indicate a direction approaching the vehicle head; "rear" (as indicated by arrow R) is used to indicate a direction opposite to "front", that is, away from the vehicle nose; "inner" (as indicated by arrow M) is used to indicate a direction approaching the vehicle interior; and "outer" (as indicated by arrow L) is used to indicate the opposite direction from "inner", that is, away from the vehicle interior. It should be noted, however, that these directional terms are used merely to more intuitively illustrate the technical solution of the present invention with the aid of the drawings, and should not be construed as limiting the scope of the present invention in any way.

According to one aspect of the present invention, a window sealing assembly for attachment to a vehicle door is provided. The door is typically hinged to the vehicle body (not shown) to open and close the passenger compartment, and when the door is open, the vehicle operator as well as passengers, cargo, etc. may enter and exit the compartment; when the doors are closed, the vehicle compartment forms an enclosed space that provides a comfortable ride for the driver and passengers of the vehicle to protect the driver and passengers from the environment outside the vehicle, which is particularly advantageous when the vehicle is traveling at high speeds. This is because, when the vehicle is traveling at a high speed, a high-speed airflow is generated on the vehicle body, and if the high-speed airflow enters the vehicle cabin, the high-speed airflow itself and the noise generated by the high-speed airflow inevitably affect the comfort of the driver and passengers, and even the safety of driving. Therefore, the degree of sealing of the vehicle cabin directly affects the comfort and safety of the vehicle. The utility model discloses just provide for the airtight degree that improves the carriage.

As shown in fig. 1, the vehicle door according to the present invention mainly includes a door main body 100, the door main body 100 is generally formed of a stamped and formed sheet metal member, and is provided with a window 110 extending through the door main body 100 in the inside-outside direction, and due to the presence of the window 110, a driver and a passenger of the vehicle will obtain a larger field of view and be allowed to interact with the outside of the vehicle through the window 110. In order to be able to close this window opening 110 in order to seal the passenger compartment, the door is further provided with a window pane (not shown) which is attached to the door body 100, typically in a liftable manner, and which extends from the interior of the door body 100 up and down through an opening provided in the bottom wall of the window opening 110 into the window opening 110. When the window glass is in the bottom position, most or even all of the window glass is housed in the door main body 100, thereby opening the window opening 110; when the window is in the top position, the window closes the window opening 110; and partially opens the window opening 110 when the window is in a position between the top and bottom positions. Generally, the raising and lowering of the window glass is controlled by a driver or passenger adjacent thereto. The connection relationship and the positional relationship between the window glass and other components (e.g., a window glass drive device, a window lock device, etc.) in the door main body 100 are well known to those skilled in the art. In general, there is a gap between the window glass and the side wall and the bottom wall of the window opening 110, even when the window glass is in the top position (i.e., the position in which the window opening 110 is closed). Due to the presence of the gap, dust, rain water, etc. may enter the door main body 100 through the gap to contaminate the driving device of the window glass, and when the vehicle is running at high speed, high-speed airflow may enter the vehicle compartment through the gap even if the window glass is in the top position, thereby generating large noise and causing the driving comfort and safety to be impaired.

In order to close the gap between the window glass and the side wall and the bottom wall of the window 110 to protect the components inside the door body 100 from contamination and to ensure the comfort and safety of the driver and passengers in the vehicle compartment, the door according to the present invention further comprises a window sealing assembly arranged along the side wall and the bottom wall of the window 110.

In order to close the gap between the window glass and the bottom wall of the window 110, the window sealing assembly includes an inner wiper 210 (e.g., made of an elastic body such as a rubber material) arranged along the bottom wall of the window 110 on the side of the window glass close to the vehicle interior, the inner wiper 210 being generally in the form of a strip or plate extending in the front-rear direction and configured to interfere with the window glass and to be elastically deformed thereby to be brought into close abutment with the window glass so as to wipe off water droplets, water mist, dust and the like on the inner side surface of the window glass, thereby preventing the water droplets, water mist, dust and the like from entering the interior of the door main body 100 through the gap between the inner side surface of the window glass and the bottom wall of the window 110, while the inner wiper 210 also being capable of preventing the window glass from shaking, thereby exerting an effect of reducing noise.

Further, in order to close the gap between the window pane and the side wall of the window pane 110, the window sealing assembly further includes a sealing strip 220 (e.g., made of an elastic body such as a rubber material) arranged along the side wall of the window pane 110 on both front and rear sides of the window pane, the sealing strip 220 including a front sealing strip 222 located in front of the window pane and a rear sealing strip 223 located in rear of the window pane, and in which a guide groove is provided, the guide groove being configured to receive an edge of the window pane, so that the sealing strip 220 guides the window pane and closely abuts the inside and outside surfaces of the window pane when the window pane moves. Therefore, the weather strip 220 can close the gap between the window glass and the side wall of the window 110 to prevent air flow, water drops, water mist, dust, and the like from entering the vehicle compartment through the gap between the window glass and the side wall of the window 110, and the weather strip 220 can also prevent the window glass from shaking, thereby achieving an effect of reducing noise.

Although the window seal assembly largely closes the gap between the window glass and the bottom and side walls of the window 110 by the inner water cut 210 and the bead 220, a small gap may still occur at the junction of the inner water cut 210 and the bead 220, which adversely affects the comfort and safety of the occupants of the vehicle when the vehicle is traveling at high speeds. This is because, when the vehicle is running at a high speed, a high-speed moving airflow is generated around the vehicle, and such a high-speed airflow may enter the vehicle through the small gap, and a large noise is generated based on a principle similar to "whistling" when passing through the small gap. To solve this problem, as more clearly shown in the two partial enlarged views in fig. 1, the inner water cut 210 extends in the front-rear direction until at least one of the front end 212 and the rear end 213 thereof partially overlaps the weather strip 220 in the inside-outside direction, in other words, the front end 212 and/or the rear end 213 of the inner water cut 210 overlaps the weather strip 220 in the inside-outside direction, thereby forming a front overlap region OV1 and/or a rear overlap region OV 2. Furthermore, the window sealing assembly further comprises an airflow blocker located in the front overlap region OV1 and/or the rear overlap region OV2 and configured to block the airflow through the front overlap region OV1 and/or the rear overlap region OV2, whereby the airflow blocker improves the hermeticity of the vehicle cabin, and in particular is capable of interfering with and even preventing the airflow through the front overlap region OV1 and/or the rear overlap region OV2, thereby reducing or even eliminating the noise generated by the airflow.

In one embodiment of the present invention, the front end 212 of the inner water cutter 210 overlaps the weatherstrip 220 in the inward and outward direction forming a forward overlap region OV1, the air flow barrier is located in the forward overlap region OV1, and the rear end 213 of the inner water cutter 210 abuts, in particular, but does not overlap, the weatherstrip 220 (i.e., there is no rearward overlap region OV 2). In another embodiment, the rear end 213 of the inner water cut 210 overlaps the weatherstrip 220 in the inward and outward direction forming a rear overlap region OV2, the airflow blocker is located in the rear overlap region OV2, and the front end 212 of the inner water cut 210 abuts, in particular, but does not overlap (i.e., there is no front overlap region OV1) the weatherstrip 220. In this configuration, the airflow blocker is only in the forward overlap region OV1, with the rear end 213 of the inner water cut 210 abutting the weatherstrip 220; alternatively, the airflow blocker is only in the rear overlap region OV2, with the front end 212 of the inner water jet 210 abutting the weatherstrip 220; this not only interferes or even impedes the passage of air flow to reduce noise, but also greatly reduces the difficulty of manufacturing and assembling the inner water cut 210 and the sealing strip 220. Of course, in an alternative embodiment, both the forward end 212 and the rear end 213 of the inner water cut 210 overlap the bead 220 in the inward and outward direction, forming both a forward overlap region OV1 and a rearward overlap region OV2, and the airflow blocker is located in both the forward overlap region OV1 and the rearward overlap region OV 2.

Next, a specific embodiment of the airflow blocker is described with reference to fig. 2 to 4, wherein fig. 2 to 4 show the specific embodiment of the airflow blocker in case that the rear end 213 of the inner water cut 210 overlaps the sealing strip to form a rear overlap region OV2 and the airflow blocker is provided in the rear overlap region OV 2. In particular, to illustrate the airflow barriers on the inner water cut 210, the inner water cut 210 in fig. 2 is horizontally turned 180 degrees with respect to the inner water cut 210 in fig. 1 to illustrate the inside surface of the inner water cut 210 facing the vehicle interior, and fig. 4 illustrates the arrangement of the inner water cut 210 and the airflow barriers on the weather strip 220 in a cross-sectional view.

As shown in fig. 2, the airflow blocker comprises at least one first protrusion 211 provided on the rear end 213 of the inner water cut 210, which first protrusion 211 protrudes from the rear end 213 of the inner water cut 210 towards the sealing strip 220 in the configuration shown in fig. 1, in particular, the first protrusion 211 abuts the sealing strip 220. As shown in fig. 3, the airflow blocker further comprises at least one second protrusion 221 provided on the sealing strip 220, which second protrusion 221 protrudes from the sealing strip 220 towards the rear end 213 of the inner water cut 210 in the configuration shown in fig. 1, in particular, the second protrusion 221 abuts the rear end 213 of the inner water cut 210. Due to the presence of the first protrusion 211 and the second protrusion 221, the airflow cannot pass (at least cannot pass smoothly) through the rear overlap region OV2, thereby reducing noise and improving the sealing of the vehicle compartment. Alternatively, as shown in fig. 4, the first protrusion 211 and the second protrusion 221 abut each other. This configuration facilitates the assembly of the inside water cutter 210, and specifically, when the inside water cutter 210 is assembled, the rear end 213 of the inside water cutter 210 may be first arranged in such a manner that the first protrusion 211 abuts the second protrusion 221, and then the inside water cutter 210 may be arranged step by step along the bottom wall of the window opening 110 in the back-and-forth direction until the front end 212 of the inside water cutter 210 abuts the sealing strip 220, which makes the assembly of the inside water cutter 210 more convenient, and eliminates a gap between the front end 212 of the inside water cutter 210 and the sealing strip 220, thereby providing a guarantee for the sealing of the front end of the inside water cutter 210.

In an alternative embodiment, as shown in fig. 2 and 4, the airflow obstructing member includes a plurality of (two are shown in the drawing) first protrusions 211 provided on the rear end 213 of the inner water cutter 210 and a plurality of (two are shown in the drawing) second protrusions 221 provided on the sealing strip 220, and wherein the plurality of first protrusions 211 and the plurality of second protrusions 221 are staggered in the front-rear direction, in particular, each first protrusion 211 abuts one of the second protrusions 221, more particularly, each first protrusion 211 abuts two second protrusions 221 located on both sides thereof. In this configuration, the plurality of first protrusions 211 and the plurality of second protrusions 221 form a sandwich structure that can more effectively prevent the passage of air flow and has a sound-insulating function, and particularly, when each of the first protrusions 211 abuts against one of the second protrusions 221, it can also function to easily position the inner water cutter 210 as described above.

In particular, as shown in fig. 4, the first protrusion 211 is oriented to slope inwardly and forwardly (i.e., toward the window pane) from the rear end 213 of the inner water cutter 210, while the second protrusion 221 is oriented to slope outwardly and rearwardly (i.e., away from the window pane) from the weatherstrip 220. This configuration may further facilitate the assembly of the inner water cut 210 because, typically, the sealing strip 220 is assembled first and then the inner water cut 210 is assembled. Therefore, by orienting the second protrusion 221 rearward and outward, the resistance to the first protrusion 211 sliding past the second protrusion 221 in the front-to-rear direction can be reduced, which in turn reduces the resistance to the assembly of the inner water cutter 210.

In particular, as shown in fig. 4, the first 211 and second 221 projections are in the form of bars extending (for example, in a vertical direction), in particular having a tapered cross section, more particularly a triangular cross section. This configuration makes the first protrusion 211 and the second protrusion 221 more easily elastically deformable, thereby further reducing resistance when the inner water cut 210 and the sealing tape 220 are assembled.

While the particular embodiment of the airflow blocker has been described above in the case where the rear end 213 of the inner water cut 210 overlaps the weatherstrip to form the rear overlap region OV2 and the airflow blocker is provided in the rear overlap region OV2, it will be appreciated by those skilled in the art that the particular embodiment of the airflow blocker applies equally to the case where the leading end 212 of the inner water cut 210 overlaps the weatherstrip to form the frontal overlap region OV1 and where the airflow blocker is provided in the frontal overlap region OV1, although as described above in relation to the frontal overlap region OV1, the first protrusion 211 may be oriented to slope inwardly and rearwardly (i.e., toward the window glass) from the front end 212 of the inner water cut 210, while the second protrusion 221 is oriented to slope outwardly and forwardly (i.e., away from the window pane) from the seal strip 220 to reduce resistance when the inner water cut 210 and seal strip 220 are assembled.

According to another aspect of the present invention, a vehicle door is also proposed, comprising a door body 100, said door body 100 being provided with a window opening 110 extending through said door body 100 in an inner and outer direction, and said door body 100 further comprising a window glass for closing and opening said window opening 110. The door further includes a window sealing assembly disposed along the side wall and the bottom wall of the window 110 as described above, and due to the presence of the window sealing assembly, air flow cannot pass through the gap between the window glass and the side wall and the bottom wall of the window 110, thereby improving the sealing of the vehicle compartment and reducing noise during vehicle running, particularly high-speed running, thereby ensuring the comfort and safety of the driver and passengers.

Alternative but non-limiting embodiments of a window sealing assembly and a vehicle door according to the invention are described in detail above with the aid of the accompanying drawings. Modifications and additions to the techniques and structures, as well as re-combinations of features in various embodiments, which do not depart from the spirit and substance of the disclosure, will be readily apparent to those of ordinary skill in the art as included within the scope of the invention. Accordingly, such modifications and additions as can be envisaged within the teachings of the present invention are considered to be part of the present invention. The scope of the present invention includes both equivalents known at the time of filing and equivalents not yet foreseen.
