Description

Technical Field

[0001] The present invention particularly relates to a flush door structure, a door assembly, and a vehicle. Background Art

[0002] Some vehicles utilize flush-type door structures, which often include a sealing strip located, at least in large part, between the door sheet metal and the side window glass. This sealing strip is typically fixed to the door and must both provide a sealing function and form a slidable connection with the side window glass in the vertical direction, allowing the side window glass to slide up and down relative to the door sheet metal. Due to the need to achieve both sealing and a slidable connection, this sealing strip has an overly complex design. This complex design indirectly increases vehicle production costs and results in a flush-type door structure with a complex matching structure between the door sheet metal and the side window glass, making the side window glass difficult to install.

[0038] Example 1

[0039] like Figure 1 and Figure 2As shown, this embodiment provides a vehicle, which includes a door assembly arranged at the left front part, and the door assembly adopts a flush door structure, including a door sheet metal 1, a B-pillar trim 2, a side window glass 3 and a clamping block 4; wherein, the clamping block 4 is fixed on the door sheet metal 1, and the side window glass 3 includes a glass body 30 and a matching block 31 fixed on the surface of the glass body 30 facing the interior of the vehicle, and a clamping groove 311 is provided on the matching block 31 with an opening facing the door sheet metal 1. The clamping block 4 extends into the clamping groove 311, forms a clamping connection with the clamping block 4 in the front-back and left-right directions, and is slidably connected to the matching block 31, so that the side window glass 3 can slide up and down relative to the door sheet metal 1.

[0040] Based on the above, there is a spacing space 5 between the side window glass 3 and the B-pillar trim 2. The B-pillar trim 2 includes an inner panel 21 and a first sealing strip 22 fixedly connected to the inner panel 21. Part of the first sealing strip 22 extends between the inner panel 21 and the side window glass 3, and this part of the first sealing strip 22 abuts against the side window glass 3 and blocks the spacing space 5. In addition, the flush door structure also includes a second sealing strip 6. The second sealing strip 6 is located in front of the clamping block 4 and the mating block 31. The second sealing strip 6 is fixedly connected to the door sheet metal 1 and abuts against the surface of the side window glass 3 facing the interior of the vehicle, and also blocks the space between the door sheet metal 1 and the side window glass 3.

[0041] As can be seen from the above description, the flush-type door structure provided in this embodiment utilizes the cooperation of the mating block 31 and the clamping block 4 to form a sliding connection between the side window glass 3 and the door sheet metal 1. Furthermore, given the design features of the mating block 31, including the latching slot 311 opening toward the clamping block 4, the first sealing strip 22 being secured to the inner panel 21, the second sealing strip 6 being secured to the door sheet metal 1, the first sealing strip 22 sealing between the B-pillar trim 2 and the glass body 30, and the second sealing strip 6 sealing between the door sheet metal 1 and the side window glass 3, it is readily apparent that:

[0042] When the flush door structure of this embodiment is assembled, the mating block 31 is engaged with the locking block 4 to simultaneously align the door sheet metal 1 and the second sealing strip 6 with the side window glass 3. When the B-pillar trim 2 is installed, the first sealing strip 22 abuts the side window glass 3. Thus, in this embodiment, both the first sealing strip 22 and the second sealing strip 6 perform only a sealing function.

[0043] In summary, this embodiment utilizes two separate sealing strips (i.e., first sealing strip 22 and second sealing strip 6) and a clamping block 4 to achieve both sealing and slidable connection between the side window glass 3 and the door sheet metal 1. Consequently, the flush door structure of this embodiment simplifies the design complexity of the sealing strips, indirectly reducing vehicle production costs. Furthermore, the door sheet metal 1 and the side window glass 3 do not require an overly complex mating structure, making installation of the side window glass 3 easier.

[0044] For the above vehicle, the following is a more detailed example setup:

[0045] Please continue reading Figure 1 and Figure 2 The B-pillar trim 2 includes an exterior trim 23 and the aforementioned inner panel 21, which are arranged in sequence from the outside to the inside. The exterior trim 23 is fixed on the surface of the inner panel 21 facing the outside of the vehicle. When the side window glass 3 and the B-pillar trim 2 are assembled, the exterior trim 23 and the side window glass 3 are flush in appearance. In the left and right directions, the surface difference between the exterior trim 23 and the side window glass 3 is 0 or close to 0. At the same time, part of the first sealing strip 22 is sealed between the B-pillar trim 2 and the side window glass 3. The first sealing strip 22 is in contact with both the exterior trim 23 and the side window glass 3.

[0046] In more detail, the first sealing strip 22 exemplarily includes a connecting body 221 and a first lip body 222, wherein the connecting body 221 is an L-shaped body with an opening facing backward, the connecting body 221 is connected to the surface of the inner panel 21 facing the vehicle interior as a whole, and wraps the front end of the B-pillar trim 2; the connecting body 221 includes a first portion extending in the front-to-back direction and a second portion extending in the left-to-right direction, the first portion is located on the right side of the inner panel 21, the second portion is connected to the first portion as a whole, and extends from the first portion to the inner panel The first lip 222 is located between the B-pillar trim 2 and the side window glass 3 and is integrally connected to the second portion of the connector 221. The first lip 222 abuts against the glass body 30 at its front end and against the exterior trim 23 at its rear end, thereby blocking the spacing space 5 between the B-pillar trim 2 and the glass body 30.

[0047] Please continue reading Figure 1 and Figure 2 For example, the second sealing strip 6 includes a sealing body 61 and a second lip 62, wherein the sealing body 61 is a special-shaped body and is fixedly arranged on the surface of the door sheet metal 1 facing the vehicle exterior by bonding. The sealing body 61 is provided with a slot 611 with an opening facing forward, and the slot 611 is used to cooperate with the door interior panel (not shown) (that is, to provide a mounting point for the door interior panel); corresponding to the design of the sealing body 61, two second lips 62 are provided in this embodiment, and the two second lips 62 are arranged on the surface of the sealing body 61 facing the vehicle exterior at intervals, and are formed by the sealing body 61 each extending toward the vehicle exterior; as shown in FIG. Figure 1 and Figure 2As shown, when the flush door structure is assembled, the second lip 62 abuts against the surface of the side window glass 3 facing the interior of the vehicle, so that the second sealing strip 6 blocks the space between the side window glass 3 and the door sheet metal 1 in front of the clamping block 4 and the matching block 31 to achieve sealing.

[0048] It is understandable that the connection method between the second sealing strip 6 and the vehicle door sheet metal 1 is not limited to the aforementioned bonding. In possible embodiments, the second sealing strip 6 can be fixedly connected to the vehicle door sheet metal 1 through common fixing methods such as snap-fitting, concave-convex fitting, and interference fitting.

[0049] Please continue reading Figure 2 and Figure 3 In a possible embodiment, the second sealing strip 6 is part of the door window frame sealing strip; in addition to the second sealing strip 6, the door window frame sealing strip also includes a body 7 for sealing the upper and front parts of the window, and the body 7 is fixedly connected to the door sheet metal 1 by common fixing methods such as snap connection, concave-convex fit, and interference fit; at the same time, in this embodiment, the second sealing strip 6 is located at the rear end of the door window frame sealing strip, and is a strip-shaped body extending downward from the rear end of the body 7.

[0050] Based on the above, in a possible embodiment, the assembly order of the vehicle door sheet metal 1, the clamping block 4 and the vehicle door window frame sealing strip can be: the clamping block 4 is first fixed to the vehicle door sheet metal 1, and then the vehicle door window frame sealing strip is fixedly connected to the vehicle door sheet metal 1.

[0051] Please return to continue reading Figure 1 and Figure 2 The mating block 31 exemplarily includes a block body 312 and an abutment arm 313; wherein the block body 312 is approximately Y-shaped, and the block body 312 is fixedly connected to the surface of the glass body 30 facing the interior of the vehicle by gluing, and the block body 312 is provided with the aforementioned card slot 311, and a first protrusion 314 and a second protrusion 315 are respectively provided on the inner walls on the two opposite sides of the card slot 311. The first protrusion 314 and the second protrusion 315 are used to hook with different positions of the card block 4 on the two opposite sides of the card block 4 to form a card connection between the card block 4 and the mating block 31 in the left and right directions, so that after the card block 4 is inserted into the card slot 311, it cannot be easily removed from the mating block 3 in the left and right directions; in addition, there are two end portions separated from each other on the right end of the Y-shaped block body 312 to form the opening of the aforementioned card slot 311, and the two end portions are respectively connected to an abutment arm 313 as a whole.

[0052] In this embodiment, the design of the abutting arm 313 is as follows:

[0053] The abutment arm 313 is located to the right of the first and second protrusions 314 and 315. It is a resilient, shaped body with one end integrally connected to the block body 312 and extending from this end toward the inside of the slot 311. The abutment arm 313 is used to abut the block 4 to apply a force toward the inside of the vehicle, thereby causing the block 4, which is inserted into the slot 311, to engage with the first and second protrusions 314 and 315.

[0054] like Figure 4 As shown, the abutment arm 313 includes a body 3131 and a head 3132, which are connected as one body. The body 3131 is connected to the block body 312 as one body, and the end of the body 3131 connected to the block body 312 is its thickest part. Except for the end connected to the block body 312, the rest of the body 3131 is designed to be relatively thin. Correspondingly, the head 3132 is designed to be thicker than the "rest" of the body 3131.

[0055] Based on the aforementioned design of the body 3131 and the head 3132, it can be seen that as the abutting arm 313 is farther away from the connection point with the block body 312, the thickness of the abutting arm 313 has the characteristic of first becoming smaller and then becoming larger. This characteristic makes the abutting arm 313 have a shape that is thick at both ends and thin in the middle.

[0056] Based on the above, the reason why the end of the abutment arm 313 connected to the block body 312 is thicker in this embodiment is to ensure the stability of the connection between the abutment arm 313 and the block body 312; the reason why the middle part of the abutment arm 313 is thin is to ensure that the abutment arm 313 can more easily undergo elastic deformation under the extrusion of the block 4; the reason why the head 3132 of the abutment arm 313 is thicker is to combine the design of the thicker connection end of the abutment arm 313 and the block body 312 to ensure that the abutment arm 313 has considerable elasticity, thereby ensuring that the abutment arm 313 can better exert force on the block 4.

[0057] It is understood that in a possible embodiment, the block body 312 and the abutting arm 313 are made of different materials and are connected as a whole by two-color injection molding; for example, the block body 312 can be made of polyoxymethylene (POM) and the abutting arm 313 can be made of thermoplastic polyolefin (TPO). To further illustrate that the abutting arm 313 and the block body 312 are made of different materials, Figure 4 The solid line (see the arrow) in the figure illustrates the boundary between the abutment arm 313 and the block body 312. It can also be understood that in a possible embodiment, the first sealing strip 22 can also be fixedly connected to the inner plate body 21 by bonding.

[0058] Please continue reading Figure 1 and Figure 2The locking cam 314 is fixed on the locking cam 316 by the locking cam 318, and the locking cam 316 is fixed on the locking cam 318. The locking cam 314 is fixed on the locking cam 316, and the locking cam 316 is fixed on the locking cam 318.

[0059] Please continue reading Figure 1 and Figure 2 In addition to the aforementioned block body 312 and abutment arm 313, the mating block 31 also illustratively includes a functional tongue 316. This strip-shaped tongue 316 extends rearward from the rear surface of the block body 312. When the flush door structure is assembled, the tongue 316 extends beyond the space 5 between the B-pillar trim 2 and the side window glass 3, reaching the inner side (right side) of the B-pillar trim 2 and spaced from it. The tongue 316 is designed to coordinate with the hooking relationship between the block body 312 and the latch block 4 to restrict the leftward movement of the side window glass 3. In more detail, when the vehicle is driving or the door is opened or closed, based on the fitting clearance between the side window glass 3 and the surrounding parts, the side window glass 3 will move slightly in the left and right directions (or vibrate or swing). After the functional tongue 316 is provided, when the side window glass 3 moves to the left (i.e., toward the outside of the vehicle), the functional tongue 316 will contact the connector 221 of the B-pillar trim 2 and be hindered by the connector 221, thereby restricting its movement, and ultimately restricting the leftward movement of the side window glass 3; correspondingly, when the side window glass 3 moves to the right (i.e., toward the inside of the vehicle), the fitting relationship between the fitting block 31 and the slot 311 will restrict the rightward movement of the side window glass 3.

[0060] Based on the above, in a possible implementation manner, the steps of assembling the flush door structure in this embodiment may be:

[0061] S1: Fix the clamping block 4 on the door sheet metal 1;

[0062] S2: Install the door window frame sealing strip on the door sheet metal 1;

[0063] S3: Install side window glass 3;

[0064] S4: Install B-pillar trim 2;

[0065] S5: Install the door interior panel.

[0066] Example 2

[0067] As in the first embodiment, this embodiment also provides a vehicle, which includes a door assembly provided at the left front portion. The door assembly adopts a flush door structure, and the flush door structure basically adopts the structure and design as described in the first embodiment.

[0068] The difference between this embodiment and the first embodiment is that Figure 5 As shown, the flush door structure of this embodiment includes a third sealing strip 8 connected to the door sheet metal 1, and a protruding foot 24 extending to the right from its right surface is provided on the inner panel 21. The protruding foot 24 is located on the same side of the mating block 31 and the first sealing strip 22, and there is a gap between the first sealing strip 22 and the mating block 31. Correspondingly, the third sealing strip 8 is convex and is located on the rear side of the clamping block 4 and the matching block 31; after the flat-type door structure is assembled, the B-pillar trim 2 is pressed on the third sealing strip 8, and the larger diameter end of the third sealing strip 8 is the part where it contacts (or is tightly attached to) the door sheet metal 1, and part of the larger diameter end of the third sealing strip 8 extends to the right side of the functional tongue 316 and the protruding foot 24, and is against the right surface of the protruding foot 24; at the same time, the smaller diameter end of the third sealing strip 8 extends between the first sealing strip 22 and the protruding foot 24, and is against the part of the inner panel 21 in front of the protruding foot 24, the protruding foot 24 and the first sealing strip 22, and is also spaced apart from the functional tongue 316.

[0069] In this embodiment, after the flush door structure is assembled, the third sealing strip 8 blocks the space between the door sheet metal 1 and the B-pillar trim 2; in this way, based on the second sealing strip 6 and the third sealing strip 8 being respectively provided on the front and rear sides of the mating block 31 and the card block 4, the second sealing strip 6, the third sealing strip 8 and the first sealing strip 22 cooperate with each other and are arranged around the mating block 31 and the card block 4, forming an approximately surrounding sealing structure.

[0070] It should be noted that the purpose of the above-mentioned design of "forming an approximately surrounding sealing structure" is to ensure that water does not enter the dry area of ​​the vehicle when water from the outside enters the area between the second sealing strip 6 and the third sealing strip 8 under certain circumstances. More specifically, in cases such as car washing, since a high-pressure water gun is required, a small amount of water from the water gun may break through the first sealing strip 22 or other structures of the vehicle (such as the side bright strip, which belongs to the prior art and is not shown in the figure) and enter between the second sealing strip 6 and the third sealing strip 8; in this way, when the flush door structure of this embodiment adopts a surrounding sealing structure, the sealing structure can ensure that water that invades the inside of the side window glass 3 and the B-pillar trim 2 is limited between the second sealing strip 6 and the third sealing strip 8, preventing water from entering the dry area of ​​the vehicle (including but not limited to the front side of the second sealing strip 6 and the rear side of the third sealing strip 8). For ease of understanding, this embodiment is described in detail. Figure 5The arrows in the figure simulate the possible flow direction of water from the water gun.

[0071] It is understood that, given that the larger diameter end of the third sealing strip 8 is in close contact with the door sheet metal 1, the third sealing strip 8 does not necessarily need to abut against the protruding foot 24, the first sealing strip 22, and the inner panel 21 as described above, the protruding foot 24 is not necessarily required, and a portion of the third sealing strip 8 does not necessarily need to be inserted between the protruding foot 24 and the first sealing strip 22. For example, the protruding foot 24 may be omitted, and the third sealing strip 8 may abut against the B-pillar trim 2 in a manner similar to that of the second sealing strip 6. For another example, given that the larger diameter end of the third sealing strip 8 is in close contact with the door sheet metal 1, when the third sealing strip 8 forms an abutting relationship with at least one of the protruding foot 24, the first sealing strip 22, and the inner panel 21, the third sealing strip 8 can form a sealing surface with at least one of the protruding foot 24, the first sealing strip 22, and the inner panel 21, thereby achieving the sealing function of the third sealing strip 8. In general, in a possible embodiment, whether the third sealing strip 8 abuts against the protruding foot 24 , the first sealing body, and the inner plate body 21 can be flexibly determined by those skilled in the art as needed.

[0072] Please refer to Figure 5 and Figure 6 In a possible embodiment, the second and third sealing strips 6 and 8 are both part of the door and window frame sealing strip. In addition to the second and third sealing strips 6 and 8, the door and window frame sealing strip also includes a body 7 for sealing the upper and front portions of the window. In this embodiment, the second and third sealing strips 6 and 8 are integrally formed with the body 7. The second and third sealing strips 6 and 8 are both located at the rear end of the door and window frame sealing strip, extending downward from the rear end of the body 7 and spaced apart from each other from front to back. It is understood that the space between the second and third sealing strips 6 and 8 is the space reserved to avoid the block 4. It is also understood that, based on the specific needs of those skilled in the art, at least one of the second and third sealing strips 6 and 8 can be part of the door and window frame sealing strip.

[0073] Based on the above, it should also be noted that in a possible embodiment, the relationship between the door and window frame sealing strip and the door sheet metal 1 can be: the body 7 is fixed to the door sheet metal 1, the second sealing strip 6 is fixed to the door sheet metal 1 by means of bonding or clipping, and the third sealing strip 8 is merely affixed to the door sheet metal 1, making contact with the door sheet metal 1 without being directly connected to the door sheet metal 1. In this embodiment, the third sealing strip 8 is equivalent to being attached to the door sheet metal 1 by virtue of its connection with the body 7 after the other parts of the door and window frame sealing strip are fully mated with the door sheet metal 1. The reason for this design is that, in this way, when the first shilling block 4 is fixed to the door sheet metal 1, the door and window frame sealing strip is installed on the door sheet metal 1, and then the side window glass 3 is installed, then the B-pillar trim 2 is installed, and finally the door interior trim is installed, during the installation of the side window glass 3, the third sealing strip 8 will not become immobilized, thereby hindering the installation of the side window glass 3 (or increasing the difficulty of installing the side window glass 3).

[0074] In other words, when the side window glass 3 needs to be installed on the door sheet metal 1 with the door window frame sealing strip, the worker only needs to align the card slot 311 with the card block 4 and make the two engage to complete the assembly of the rear end of the side window glass 3; at the same time, if during the assembly process it is felt that the gap reserved between the third sealing strip 8 and the functional tongue 316 is too narrow and hinders the installation of the side window glass 3, the worker can directly slightly open the third sealing strip 8 and then install the side window glass 3. After the installation of the side window glass 3 is completed, the third sealing strip 8 can be moved back. It should be noted that since the B-pillar trim 2 needs to be installed later, and the B-pillar trim 2 needs to be coordinated with other parts of the vehicle (including but not limited to the door sheet metal 1), it will have a more precise positioning. At the same time, the third sealing strip 8 is configured to extend between the protruding foot 24 and the first sealing strip 22. Therefore, there is no need to worry about whether the aforementioned worker's action of moving the third sealing strip 8 back is in place. When the B-pillar trim 2 is completed, the coordination relationship between it and the third sealing strip 8 will naturally make the third sealing strip 8 in the expected design position; at the same time, based on the design that the B-pillar trim 2 will be pressed on the third sealing strip 8, when the B-pillar trim 2 is completed, the third sealing strip 8 will be firmly in the expected design position.

[0075] Of course, according to the specific needs of those skilled in the art, the third sealing strip 8 can also be connected to the door sheet metal 1 by gluing, similar to the second sealing strip 6 .

[0076] It should also be noted that the reason why the third sealing strip 8 and the functional tongue 316 are spaced apart in this embodiment is to reduce resistance to the vertical movement of the side window glass 3. However, while the third sealing strip 8 and the functional tongue 316 can be spaced apart to reduce resistance to the vertical movement of the side window glass 3, in a possible embodiment, based on the specific needs of those skilled in the art, and to ensure the sealing performance of the third sealing strip 8, a design in which the third sealing strip 8 and the functional tongue 316 are in contact or slightly abutted can also be adopted. Because the third sealing strip 8 can move relatively flexibly before the B-pillar trim 2 is assembled, even if the third sealing strip 8 and the functional tongue 316 are in contact or slightly abutted, it will not significantly increase the difficulty of assembling the flush door structure.

[0077] It can also be understood that, based on the arrangement in this embodiment where the third sealing strip 8 partially extends to the right side of the functional tongue 316, when the side window glass 3 moves to the left or right, the functional tongue 316 can restrict the movement of the side window glass 3 by contacting the first sealing strip 22 or the third sealing strip 8.

[0078] Example 3

[0079] As in the second embodiment, this embodiment also provides a vehicle, which includes a door assembly provided at the left front portion thereof, the door assembly adopts a flush door structure, and the flush door structure part adopts the structure and design as described in the second embodiment. Figure 7 and Figure 8 As shown, the differences between this embodiment and the second embodiment include: the shape of the functional tongue 316, the relationship between the functional tongue 316 and the B-pillar trim 2, the shape of the second sealing strip 6, the relationship between the second sealing strip 6 and the door sheet metal 1, the shape of the third sealing strip 8, and the relationship between the third sealing strip 8 and the door sheet metal 1. These differences are described in detail below:

[0080] like Figure 7 and Figure 8As shown, in this embodiment, the functional tongue 316 is configured such that it extends beyond the space 5 between the B-pillar trim 2 and the side window glass 3, reaching the inner side of the B-pillar trim 2 and contacting the connector 221. Furthermore, a protrusion is provided at the rear end of the functional tongue 316, which forms the contact area with the connector 221, making the contact between the functional tongue 316 and the connector 221 approximately point contact. It can be understood that, compared to the design of the functional tongue 316 spaced from the B-pillar trim 2 in the first embodiment, the contact arrangement of the functional tongue 316 with the B-pillar trim 2 in this embodiment enhances the effect of restricting the left and right movement of the side window glass 3. Furthermore, the contact area with the connector 221, rather than the larger area of ​​the non-functional tongue 316, minimizes resistance to the vertical movement of the side window glass 3 and minimizes the friction area between the functional tongue 316 and the first lip 222 during vertical movement of the side window glass 3. Of course, according to the specific needs of those skilled in the art, the functional tongue 316 can also be configured to be spaced apart from the B-pillar trim 2.

[0081] Please continue reading Figure 7 and Figure 8 Slightly different from the second embodiment, the third sealing strip 8 of this embodiment is of a different shape, with a portion extending to the rear of the protruding foot 24 and a portion extending to the right of the functional tongue 316. Furthermore, the third sealing strip 8 is provided with a groove 81 opening toward the B-pillar trim 2. This groove 81 is a U-shaped groove that fits concavely and convexly with the protruding foot 24, so that the portion of the third sealing strip 8 located in front of the groove 81 is sandwiched between the first sealing strip 22 and the protruding foot 24. In a possible embodiment, the groove 81 and the protruding foot 24 have an interference fit.

[0082] Based on the above, in a possible embodiment, to facilitate the deformation of the third sealing strip 8, holes 9 are provided on the front and rear sides of the groove 81 of the third sealing strip 8, extending vertically through the third sealing strip 8. The purpose of providing these holes 9 is to reduce the deformation resistance of the third sealing strip 8. It is understood that by reducing the deformation resistance of the third sealing strip 8, the design of the holes 9 also indirectly facilitates the fit between the B-pillar trim 2 and the third sealing strip 8, namely, workers can more easily insert the protruding feet 24 into the groove 81.

[0083] Based on the above, in a possible embodiment, after the protrusion 24 is mated with the groove 81, the inner plate 21 can be configured to be pressed onto the third sealing strip 8, that is, at this time, at least part of the left surface of the third sealing strip 8 is against the inner plate 21.

[0084] In a possible embodiment, the vehicle door and window frame sealing strip includes a second sealing strip 6 and a third sealing strip 8 as described in the second embodiment. When the vehicle door sheet metal 1 with the vehicle door and window frame sealing strip, the side window glass 3, and the B-pillar trim 2 are fully assembled, the connector 221 is configured to abut against the functional tongue 316. At this point, the functional tongue 316 is located between the connector 221 and the third sealing strip 8 and spaced apart from the third sealing strip 8. It will be appreciated that in a possible embodiment, when the functional tongue 316 moves rightward with the side window glass 3, to reduce the force applied by the third sealing strip 8 to the functional tongue 316 and the deformation resistance of the third sealing strip 8, a hole 9 is further provided in the third sealing strip 8 on the right side of the functional tongue 316 in this embodiment.

[0085] Please continue reading Figure 7 and Figure 8 Unlike the design in the second embodiment in which the third sealing strip 8 is only attached to the vehicle door sheet metal 1, the flush door structure provided in this embodiment also includes a guide member 10 for cooperating with the third sealing strip 8. The guide member 10 is a special-shaped member and is fixed to the vehicle door sheet metal 1 (through common fixing methods such as integral molding, pasting, or welding), and a space for accommodating the guide member 10 is provided on the third sealing strip 8. The third sealing strip 8 is provided with a hooking lip 82 protruding toward the guide member 10 in the space. The hooking lip 82 is hooked with a recessed portion on the guide member 10, so that the third sealing strip 8 is snap-fitted with the guide member 10 in the left-right direction.

[0086] It can be understood that the cooperation relationship between the third sealing strip 8 and the guide member 10 is an easily releasable cooperation relationship. Based on this, when the third sealing strip 8 is part of the door window frame sealing strip, the cooperation between the guide member 10 and the third sealing strip 8 can prevent the third sealing strip 8 from shaking easily, and can enable workers to easily release the cooperation between the guide member 10 and the third sealing strip 8 when they feel that the third sealing strip 8 interferes with the assembly of the side window glass 3, and then push away the third sealing strip 8, thereby achieving smooth installation of the side window glass 3; thereafter, after the worker installs the side window glass 3, he or she can re-coordinate the guide member 10 with the third sealing strip 8 to achieve accurate resetting of the third sealing strip 8.

[0087] Please continue reading Figure 7 and Figure 8 The configuration of the second sealing strip 6 in this embodiment basically adopts the configuration of the second sealing strip 6 in Example 2; one of the differences between the second sealing strip 6 in this embodiment and the second sealing strip 6 in Example 2 is that the second sealing strip 6 in this embodiment is not fixed to the vehicle door sheet metal 1 by pasting or the like, but: similar to the cooperation method between the third sealing strip 8 and the guide part 10, the flush door structure provided by this embodiment also includes a guide part 10 for cooperating with the second sealing strip 6, and on the rear side of the guide part 10, the second sealing strip 6 is hooked with the guide part 10 and forms a snap connection in the left and right directions.

[0088] Based on the above, the second difference between the second sealing strip 6 in this embodiment and the second sealing strip 6 in the second embodiment is that a third lip 63 extending toward the vehicle door sheet metal 1 is provided on the sealing body 61. The third lip 63 is a portion of the slot 611 and is an arc-shaped body; the third lip 63 and the vehicle door sheet metal 1 are abutted.

[0089] As mentioned above, the third lip 63 of this embodiment is also located in front of the guide member 10 that mates with the second sealing strip 6. It defines a space on the second sealing strip 6 for accommodating the guide member 10. The space on the second sealing strip 6 for accommodating the guide member 10 is slightly larger than the volume of the guide member 10. As can be understood, the second sealing strip 6 and its mateable guide member 10 form a releasable connection with the door sheet metal 1. This connection allows the position of the second sealing strip 6 on the door sheet metal 1 to be fine-tuned by adjusting the depth of engagement between the guide member 10 and the second sealing strip 6. This allows workers to fine-tune the position of the second sealing strip 6 as needed to accommodate production or assembly errors in other vehicle components, such as the door interior panel (which mates with the second sealing strip 6).

[0090] It is understandable that after the second sealing strip 6 is hooked with the guide member 10 , the design of the third lip 63 abutting against the door sheet metal 1 and the design of the second lip 62 abutting against the door sheet metal 1 can ensure the sealing performance of the second sealing strip 6 .

[0091] It is understood that, to facilitate the cooperation of the guide member 10 with the second sealing strip 6, a hole 9 penetrating the second sealing strip 6 is also provided on the rear side of the guide member 10 in this embodiment. It is also understood that, to facilitate the cooperation of the guide member 10 corresponding to the third sealing strip 8 with the third sealing strip 8, a similar hole 9 may also be provided at a similar position on the third sealing strip 8.

[0092] It is also understood that, in possible embodiments, the aforementioned guide members 10 corresponding to the second sealing strip 6 and the guide members 10 corresponding to the third sealing strip 8 may also serve as positioning members for the second and third sealing strips 6 and 8, ensuring their accurate positioning on the vehicle door sheet metal 1. In such embodiments, whether the third lip 63 is required, and whether the second and third sealing strips 6 and 8 require additional connections to the vehicle door sheet metal 1 (e.g., adhesive bonding) in addition to their respective connections to the guide members 10, are all matters that can be flexibly designed by those skilled in the art as needed.

[0093] In summary, the present invention achieves two design purposes, namely, sealing and forming a slidable connection between the door sheet metal 1 and the side window glass 3, by using sealing strips (first sealing strip 22, second sealing strip 6) and clamping blocks 4. This simplifies the complexity of the sealing strip configuration, indirectly reduces the vehicle production cost, and eliminates an overly complex matching structure between the door sheet metal 1 and the side window glass 3, making the side window glass 3 easier to install.

[0094] Furthermore, when the first sealing strip 22 is integrally formed with the inner panel body 21, the components used to form a flush appearance are only two parts, namely the B-pillar trim 2 and the side window glass 3. That is, in order to achieve a flush appearance, it is only necessary to control the surface difference of these two parts. It can be understood that since the number of parts that need to be controlled is relatively small, it is easier for the present invention to achieve a flush design of the side window glass 3 and the B-pillar trim 2 at this time.

[0095] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
