[0050] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0051] 1 to 7 , the present invention discloses an external watertight seal for an automobile, comprising a first body 100 and a second body 200. The first body 100 has a first end close to the A-pillar of the automobile and a second end close to the B-pillar of the automobile, and the second body 200 has a third end close to the B-pillar of the automobile and a fourth end close to the C-pillar of the automobile, and further comprising:

[0052] The first connection structure 300 includes a first housing 310 connected to the second end for sealing the second end; the second connection structure 400 includes a second housing 410 connected to the fourth end for sealing the fourth end; the first housing 310 and the second housing 410 are respectively embedded with a first insert 320;

[0053] A plurality of first clamping members 700, each having a connecting portion and a clamping portion, wherein the connecting portion is connected to the sheet metal of the vehicle door, and the clamping portion is clamped to the first insert 320;

[0054] The first shell and the second shell both have a pulling surface on one side facing the interior of the vehicle, and the door has a closed state and a pop-up state; in the closed state, the pulling surface abuts against the B-pillar trim or the C-pillar trim; in the pop-up state, the pulling surface and the B-pillar trim or the C-pillar trim have a gap that allows a person to reach in, press against the pulling surface, and open the door.

[0055] The external water cut of the present application is applied to the car door of a semi-automatic door. Specifically, when the car door is unlocked by a button or an induction card on the door, the door pops open a certain gap, and the driver or passenger can put their hand into the gap and drive the pulling surface 311 to pull the door outward to open the door. That is, the present application does not need to set a handle on the outside of the door to provide a new type of hidden door handle. Compared with the traditional telescopic hidden door handle set on the outside of the door, the present application integrates the door handle with the external water cut, eliminating the cost of setting up a separate door handle, and there is no gap between it and the door handle on the outside of the door, making the outer side of the door smoother and reducing driving wind resistance.

[0056] It should be noted that the first connection structure 300 and the second connection structure 400 are both insert-molded, and the first insert 320 is already inside the first shell 310 and the second shell 410 during the injection molding, without the need for subsequent assembly.

[0057] More specifically, the present invention provides a first connection structure 300 that connects the first housing 310 to the first end and seals the opening at the first end; and a second connection structure 400 that connects the second housing 410 to the fourth end and seals the opening at the fourth end. Furthermore, first inserts 320 are embedded in the first and second housings 310, 410, respectively. A first clamping member 700 is provided on the door's sheet metal, engaging the first clamping member 700 with the first insert 320 to achieve connection between the exterior watertight fitting and the door.

[0058] In other words, the first connecting structure 300 and the second connecting structure 400 simultaneously seal the outer watertight section and connect the vehicle door. Compared to providing separate seals and connectors, this application integrates the seals and connectors of the outer watertight section into a single component, reducing costs. Furthermore, there is no need to install the connectors and seals separately, simplifying the assembly process.

[0059] Furthermore, referring to FIG. 6 , the pulling surface 311 is gradually inclined toward the outside of the vehicle from top to bottom, and the pulling surface 311 is provided with a flocking layer.

[0060] The pull surface 311 is gradually tilted toward the outside of the vehicle from top to bottom, with the upper end of the pull surface 311 positioned more inward and the lower end more outward. This allows the curvature of the pull surface 311 to better match the curvature of the fingers when inserting a palm into the gap to open the door, increasing the contact area and making door opening more comfortable. Furthermore, a flocking layer is provided on the pull surface 311, allowing the palm and fingers to contact the flocking layer when opening the door, further enhancing door opening comfort.

[0061] Further, referring to FIG. 5 , both the first housing 310 and the second housing 410 have a mounting cavity, and the first insert 320 is embedded in the mounting cavity;

[0062] A plurality of first limiting columns 312 and a plurality of first limiting holes 313 are provided on the inner wall of the installation cavity, and a plurality of second limiting columns 325 and a plurality of second limiting holes 324 are provided on the outer wall of the first insert 320. The first limiting columns 312 extend into the second limiting holes 324, and the second limiting columns 325 extend into the first limiting holes 313.

[0063] The first limiting column 312 is inserted into the second limiting hole 324 , and the second limiting column 325 is inserted into the first limiting hole 313 , so that a locking force is exerted between the first insert 320 and the first housing 310 to prevent them from loosening.

[0064] Further, referring to FIG. 4 , two ends of the first insert 320 respectively abut against two ends of the installation cavity, and a bottom of the first insert 320 abuts against the bottom surface of the installation cavity.

[0065] The two ends of the first insert 320 abut against the two ends of the installation cavity to achieve lateral limitation of the first insert 320, and the bottom abuts against the bottom surface of the installation cavity to achieve longitudinal limitation of the first insert 320, limiting it in multiple directions to prevent the first insert 320 from loosening.

[0066] Further, referring to FIG5 , the first insert 320 is arranged in a U-shape;

[0067] The first insert 320 includes a first side plate and a second side plate. A clamping groove is defined between the first side plate and the second side plate. The first clamping member 700 can extend into the clamping groove and be clamped with the first insert 320 .

[0068] 3 and 5 , the first side panel is provided with a plurality of engaging pieces 321 , each of which has an engaging surface 322 and a locking surface 323 , wherein the engaging surface 322 gradually tilts toward the second side panel along the direction in which the first engaging member 700 extends into the engaging groove;

[0069] The clamping portion is provided with a plurality of locking holes 710 . The clamping piece 321 can at least partially extend into the locking hole 710 , and the locking surface 323 abuts against the side wall of the locking hole 710 .

[0070] Specifically, before installing the external water cut, first fix the first clamping part 700 on the sheet metal of the vehicle door, then move the external water cut to the position where the clamping part is aligned with the clamping groove, and then press the external water cut down until the clamping part is clamped into the clamping groove to complete the installation, which simplifies the installation steps of the external water cut.

[0071] When the clamping part is clamped into the clamping slot, the clamping part first contacts the end of the clamping surface 322 away from the locking surface 323, and then as the clamping surface 322 and the clamping part slide relative to each other, the clamping piece 321 is squeezed and deformed until the clamping part passes over the clamping surface 322 and reaches the locking surface 323, the clamping piece 321 recovers its deformation and partially or completely extends into the locking hole 710, and at the same time, the locking surface 323 abuts against the inner wall of the locking hole 710, which can effectively prevent the clamping part from exiting the clamping slot in the opposite direction.

[0072] Furthermore, the first insert 320 further includes a bottom plate, and the first side plate and the second side plate are respectively fixed to two sides of the bottom plate;

[0073] When the locking surface 323 abuts against the side wall of the locking hole 710 , the end of the first clamping member 700 abuts against the bottom plate.

[0074] That is, the bottom plate abuts against the end of the first clamping component 700, and the locking surface 323 abuts against the side wall of the locking hole 710, so as to apply two opposite forces to the first clamping component 700 at the same time, so that the first clamping component 700 will not shake in the clamping groove, thereby avoiding external water shear shaking.

[0075] Further, referring to FIG. 11 , a third connection structure 500 is further included. The third connection structure 500 includes: a third end plate 510 and a plurality of third side plates 520 fixedly connected to the third end plate 510 . The third end plate 510 is connected to the first end, and the third side plates 520 are in contact with the side surfaces of the first body 100 .

[0076] An extension rib 530 is further provided on a side of the third end plate 510 away from the first body 100 , and the extension rib 530 is used to fit with the sheet metal of the vehicle door.

[0077] Specifically, the third end plate 510 seals the opening at the first end, and the third side plate 520 mates with the side surface of the first body 100, increasing the contact area between the third connecting structure 500 and the first body 100 and thereby strengthening the connection between the third connecting structure 500 and the first body 100. Furthermore, the extension rib 530 mates with the sheet metal, strengthening the connection between the outer watertight section and the vehicle door and preventing the outer watertight section from loosening.

[0078] Further, referring to FIG. 8 to FIG. 10 , a fourth connecting structure 600 is further included, which is connected to the third end. A second clamping member 610 extends downward from the fourth connecting structure 600. The second clamping member 610 is used to clamp with the side panel of the vehicle door.

[0079] The second clamping member 610 includes two extending plates 611 arranged opposite to each other. The inner side of each extending plate 611 is connected to a clamping plate 612 . The side ring of the vehicle door can be clamped between the two clamping plates 612 .

[0080] A fourth connecting structure 600 is provided to seal the opening at the third end. A second clip 610 extends downward from the fourth connecting structure 600. The second clip 610 clips into the door side panel, strengthening the connection between the outer watertight section and the door. Furthermore, the second clip 610 seals the opening at the door side panel.

[0081] Furthermore, there is an inlay space between each of the clamping plates 612 and the extension plate 611;

[0082] It also includes a second insert 620 with a U-shaped arrangement, and the second insert 620 includes two relatively arranged pre-tightening plates 621, and the two pre-tightening plates 621 respectively extend into one of the embedding spaces to provide a pre-tightening force to bring the two clamping plates 612 closer to each other; wherein the second insert 620 and the second clamping member 610 are embedding injection molded.

[0083] The clamping plate 612 is provided with a plurality of first limiting recesses, and the extension plate 611 is provided with a plurality of first limiting protrusions; the pre-tightening plate 621 is provided with a plurality of second limiting recesses and a plurality of second limiting protrusions, the second limiting protrusions extend into the first limiting recesses, and the first limiting protrusions extend into the second limiting recesses.

[0084] The first limiting protrusion is configured to extend into the second limiting recess, and the second limiting protrusion is configured to extend into the first limiting recess, so that there is a force for locking relative movement between the second inserts 620 and the second inserts 620, and the second inserts 620 are not easy to loosen.

[0085] Furthermore, the side of the fourth connecting structure facing the interior of the vehicle is provided with a flocking layer for contact with the B-pillar trim. The flocking layer provided on the side of the fourth connecting structure prevents direct contact between the fourth connecting structure and the B-pillar trim, preventing abnormal noise caused by friction between the fourth connecting structure and the B-pillar trim during driving. It also protects the fourth connecting structure and the B-pillar trim, extending their service life.

[0086] It should be noted that all directional indications (such as up, down, left, right, front, back, etc.) in the embodiments of the present invention are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0087] In addition, in the present invention, descriptions such as "first," "second," and "one" are for descriptive purposes only and should not be understood to indicate or imply their relative importance or implicitly specify the number of the technical features indicated. Therefore, a feature specified as "first" or "second" may explicitly or implicitly include at least one of such features. In the description of the present invention, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0088] In the present invention, unless otherwise specified or limited, the terms "connection" and "fixation" should be understood in a broad sense. For example, "fixation" can mean fixed connection, detachable connection, or integration; mechanical connection or electrical connection; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified.
