[0047] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0048] Please refer to Figure 1-Figure 11 The present invention discloses an outer water cut for an automobile, comprising a first body 100 and a second body 200, wherein 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 comprises:

[0049] The first connection structure 300 includes: a first housing 310 connected to the second end to seal the second end; the second connection structure 400 includes: a second housing 410 connected to the fourth end to seal the fourth end; the first housing 310 and the second housing 410 are respectively inlaid with a first insert 320;

[0050] 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;

[0051] 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's hand to reach in, press against the pulling surface and open the door.

[0052] The external water cut of the present application is applied to the semi-automatic door of the car. 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.

[0053] It should be noted that the first connection structure 300 and the second connection structure 400 are both insert injection-molded, and the first insert 320 is already inside the first shell 310 and the second shell 410 during injection molding, and no subsequent assembly is required.

[0054] More specifically, the present application sets a first connection structure 300 to connect the first housing 310 with the first end and seal the opening of the first end; sets a second connection structure 400 to connect the second housing 410 with the fourth end and seal the opening of the fourth end. At the same time, the first insert 320 is respectively embedded in the first housing 310 and the second housing 410, and the first clamping member 700 is set on the sheet metal of the vehicle door, so that the first clamping member 700 is clamped with the first insert 320, thereby realizing the connection between the outer water cut and the vehicle door.

[0055] That is to say, the first connection structure 300 and the second connection structure 400 simultaneously seal the outer water cut and connect the vehicle door. Compared with separately setting the seal and the connection, the present application integrates the seal and the connection of the outer water cut into one component, which reduces the cost; moreover, there is no need to install the connection and the seal separately, which simplifies the assembly steps.

[0056] Furthermore, the pulling surface 311 gradually inclines toward the outside of the vehicle from top to bottom, and the pulling surface 311 is provided with a flocking layer.

[0057] The pulling surface 311 is gradually inclined from top to bottom toward the outside of the vehicle, so that the upper end of the pulling surface 311 is closer to the inside and the lower end is closer to the outside, so that the curvature of the pulling surface 311 is more in line with the curvature of the fingers when the palm is inserted into the gap to pull the door, increasing the contact area and making the door opening more comfortable. At the same time, a flocking layer is provided on the pulling surface 311 so that the palm and fingers contact the flocking layer when opening the door, further improving the comfort when opening the door.

[0058] Furthermore, the first housing 310 and the second housing 410 each have an installation cavity, and the first insert 320 is embedded in the installation cavity;

[0059] 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, 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.

[0060] The first limiting column 312 is arranged to extend into the second limiting hole 324, and the second limiting column 325 is arranged to extend into the first limiting hole 313, so that there is a force for locking relative movement between the first insert 320 and the first housing 310, and it is not easy to loosen.

[0061] Furthermore, two ends of the first insert 320 abut against two ends of the installation cavity respectively, and a bottom of the first insert 320 abuts against a bottom surface of the installation cavity.

[0062] 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.

[0063] Further, the first insert 320 is arranged in a U shape;

[0064] 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 clamp with the first insert 320 .

[0065] Furthermore, the first side plate is provided with a plurality of engaging pieces 321, the engaging pieces 321 having an engaging surface 322 and a locking surface 323, and the engaging surface 322 gradually inclines toward the second side plate along the direction in which the first engaging member 700 extends into the engaging groove;

[0066] The clamping portion is provided with a plurality of locking holes 710 , and the clamping piece 321 can at least partially extend into the locking hole 710 , so that the locking surface 323 abuts against the side wall of the locking hole 710 .

[0067] 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, thereby simplifying the installation steps of the external water cut.

[0068] When the snap-in portion is snapped into the snap-in slot, the snap-in portion first contacts the end of the snap-in surface 322 away from the locking surface 323, and then as the snap-in surface 322 and the snap-in portion slide relative to each other, the snap-in piece 321 is squeezed and deformed until the snap-in portion passes over the snap-in surface 322 and reaches the locking surface 323, and the snap-in piece 321 recovers its deformation and partially or completely extends into the locking hole 710. At the same time, the locking surface 323 abuts against the inner wall of the locking hole 710, which can effectively prevent the snap-in portion from exiting the snap-in slot in the opposite direction.

[0069] 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;

[0070] 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.

[0071] 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 simultaneously apply two opposite forces to the first clamping component 700, so that the first clamping component 700 will not shake in the clamping groove, thereby avoiding external water shear shaking.

[0072] Furthermore, a third connection structure 500 is included, and 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;

[0073] 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.

[0074] Specifically, the third end plate 510 can seal the opening of the first end, and the third side plate 520 is fitted with the side of the first body 100, which can increase the contact area between the third connection structure 500 and the first body 100, so as to enhance the connection strength between the third connection structure 500 and the first body 100. At the same time, the extension rib 530 is fitted with the sheet metal, which can enhance the connection strength between the outer water cut and the door, and prevent the outer water cut from loosening.

[0075] Furthermore, a fourth connecting structure 600 is included, which is connected to the third end, and a second clamping member 610 extends downward from the fourth connecting structure 600, and the second clamping member 610 is used to clamp with the side wall of the vehicle door;

[0076] 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 .

[0077] A fourth connection structure 600 is provided to seal the opening of the third end. A second clamping member 610 extends downward from the fourth connection structure 600, and the second clamping member 610 is clamped with the side panel of the vehicle door to enhance the connection strength between the outer water cut and the vehicle door. At the same time, the second clamping member 610 can seal the opening at the side panel of the vehicle door.

[0078] Furthermore, there is an inlay space between each of the clamping plates 612 and the extension plate 611;

[0079] It also includes a second insert 620 with a U-shape, and the second insert 620 includes two relatively arranged pre-tightening plates 621, and the two pre-tightening plates 621 extend into one of the embedding spaces respectively 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.

[0080] 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.

[0081] The first limiting protrusion is arranged to extend into the second limiting recess, and the second limiting protrusion is arranged 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.
