DETAILED DESCRIPTION

In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific embodiments of the present invention are described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the present invention, so the present invention is not limited by the specific embodiments disclosed below.

As shown in FIG. 1 and FIG. 2 , in the vehicle window 10, the outer water cut assembly 20 is arranged on the vehicle door sheet metal 11, and the outer water cut body 21 of the outer water cut assembly 20 is closely attached to the vehicle window glass 12 for sealing. The outer water cut assembly 20 also includes a bright trim 22, which mainly serves a decorative effect. If the bright trim 22 is deformed, the optical effect of the appearance will be affected. Therefore, it is necessary to avoid the bright trim 22 from bending under force during the assembly process.

As shown in FIG. 2 and FIG. 4 , in some embodiments of the present application, there is provided an external water-cut assembly 20 , including an external water-cut body 21 , a bright decorative strip 22 , and a detachable nail column module 23 .

The detachable nail column module 23 includes a nail column 231 and a nail column cap 232 detachably matched with the nail column 231. The outer water-cut body 21 is provided with a water-cut through hole 211. The bright decorative strip 22 is provided with a decorative strip through hole 221. The outer water-cut body 21 and the bright decorative strip 22 can be matched so that the water-cut through hole 211 is opposite to the decorative strip through hole 221. When the water-cut through hole 211 and the decorative strip through hole 221 are opposite, the nail column 231 can penetrate the decorative strip through hole 221 and the water-cut through hole 211 and detachably match with the nail column cap 232 to fix the outer water-cut body 21 and the bright decorative strip 22 together. Specifically, when the nail column 231 and the nail column cap 232 are detachably matched together, the limit head of the nail column 231 and the nail column cap 232 can be clamped on the outer water-cut body 21 and the bright decorative strip 22 respectively, or the limit head of the nail column 231 and the nail column cap 232 can be clamped on the bright decorative strip 22 and the outer water-cut body 21 respectively.

When selectively replacing the outer water-cut body 21 or the bright decorative strip 22, the nail column 231 and the nail column cap 232 can be disassembled first, so that the outer water-cut body 21 and the bright decorative strip 22 are freed from the restraint. Then, the replaced outer water-cut body 21 and the bright decorative strip 22 are matched together, so that the water-cut through hole 211 and the decorative strip through hole 221 are opposite, and the nail column 231 is passed through the water-cut through hole 211 and the decorative strip through hole 221 and then detachably matched with the nail column cap 232, and then the replaced outer water-cut body 21 and the bright decorative strip 22 are assembled together.

During the entire replacement process, the outer water-cut body 21 and the bright decorative strip 22 will not be deformed, which effectively ensures the sealing of the outer water-cut body 21 and the decorative effect of the bright decorative strip 22 after replacement.

In some embodiments, as shown in FIG. 2 and FIG. 3 , a receiving cavity 222 is provided in the bright decorative strip 22, the receiving cavity 222 is communicated with the decorative strip through hole 221, and the nail column cap 232 is located in the receiving cavity 222. When the nail column 231 and the nail column cap 232 are detachably matched together, the nail column cap 232 is blocked by the cavity wall of the receiving cavity 222 on the side of the decorative strip through hole 221 away from the water-cut through hole 211, and the limiting head of the nail column 231 is limited together with the outer water-cut body 21, so that the relative position of the bright decorative strip 22 and the outer water-cut body 21 is fixed.

In the present application, the limit head of the nail column 231 refers to the end of the nail column 231 with a larger outer diameter, and the limit head can be used in conjunction with tools such as wrenches and screwdrivers.

The size of the nail column cap 232 meets the requirement that it cannot pass through the decorative strip perforation 221, so when the nail column 231 passes through the water-cut perforation 211 and the decorative strip perforation 221 and is detachably matched with the nail column cap 232, the nail column cap 232 can be pressed against the bright decorative strip 22. As shown in Figures 4 and 5, the nail column cap 232 includes a cap body 2322 and a cap column 2321 disposed in the cap body 2322 and connected to the cap body 2322. The cap column 2321 is used to detachably match with the nail column 231, and the maximum spacing H1 defined by the brim 2324 of the cap body 2322 is greater than the aperture of the decorative strip perforation 221, so the cap body 2322 cannot pass through the decorative strip perforation 221, but abuts against the bright decorative strip 22.

Furthermore, in one embodiment, as shown in FIG. 2 , the diameter of the trim hole 221 is larger than the outer diameter of the nail column 231 , and the nail column 231 may not contact the bright trim 22 when passing through the trim hole 221 , thereby minimizing the impact on the bright trim 22 during the replacement process.

The opening of the space surrounded by the cap body 2322 faces the decorative strip through hole 221, the nail column 231 is inserted into the space surrounded by the cap body 2322 and detachably cooperates with the cap column 2321, and the brim 2324 of the cap body 2322 abuts against the cavity wall of the accommodating cavity 222. When the nail column 231 and the nail column cap 232 are detachably cooperated together, the bright decorative strip 22 is pressed by the nail column cap 232 in the direction close to the outer water-cut body 21, so that the relative position of the bright decorative strip 22 and the outer water-cut body 21 is fixed.

Furthermore, in some embodiments, the accommodating cavity 222 has an opening (not shown in the figure), and after the nail column cap 232 is detached from the nail column 231, the nail column cap 232 can slide in the accommodating cavity 22 and slide out from the opening. When the bright decorative strip 22 needs to be replaced, after the nail column cap 232 is detached from the nail column 231, the nail column cap 232 in the old bright decorative strip 22 can be taken out and used in the new bright decorative strip 22, further saving the replacement cost.

Furthermore, in one embodiment, as shown in FIG4 , the detachable nail column module 23 further includes a fastening sleeve 233. As shown in FIG2 , the fastening sleeve 233 is inserted into the water-cut through-hole 211 of the outer water-cut body 21. The nail column 231 passes through the fastening sleeve 233 and is inserted into the decorative strip through-hole 221, and then detachably cooperates with the nail column cap 232. The fastening sleeve 233 plays a certain protective role on the outer water-cut body 21, preventing the nail column 231 from directly contacting the outer water-cut body 21, resulting in the nail column 231 directly rubbing against the outer water-cut body 21 when passing through the water-cut through-hole 211.

As shown in Figures 10 to 12, the fastening sleeve 233 and the outer water-cut body 21 can be fixedly connected together. If the outer water-cut body 21 needs to be replaced, the fastening sleeve 233 can be replaced together with the outer water-cut body 21, while the nail column 231 and the nail column cap 232 can be retained.

Furthermore, in some embodiments, as shown in Figures 4 and 6, the detachable nail column module 23 further includes a limiting member 234. The limiting member 234 includes a connecting portion 2341 and a limiting portion 2342, the connecting portion 2341 is connected to the outer water-cut body 21 or the bright decorative strip 22, the limiting portion 2342 cooperates with the nail column 231 to form an assembly unit, and the nail column cap 232 is detachably connected to the assembly unit.

After the nail column 231 passes through the water-cut through hole 211 and the decorative strip through hole 221, the relative position between the nail column 231 and the limiting part 2342 is fixed to form an assembly unit, and the nail column cap 232 is detachably connected to the assembly unit, thereby limiting the relative position between the outer water-cut body 21 and the bright decorative strip 22. After the nail column 231 is removed from the water-cut through hole 211 and the decorative strip through hole 221, the nail column 231 is separated from the limiting part 234, and the above-mentioned assembly unit is disassembled to release the restraint on the nail column cap 232, thereby allowing the outer water-cut body 21 and the bright decorative strip 22 to be separated.

After assembly, the nail column 231 passes through the connecting portion 2341 , so that the relative position between the nail column 231 and the limiting portion 2342 is fixed.

The fastening sleeve 233 is partially inserted into the through hole of one of the outer water-cut body 21 and the bright decorative strip 22 connected to the connecting portion 2341. The fastening sleeve 233 also penetrates the connecting portion 2341, and the nail column 231 is inserted into the fastening sleeve 233.

Specifically, in some embodiments, as shown in FIG. 2 , the connection portion 2341 is connected to the outer water-cut body 21, and the limiting portion 2342 passes through the decorative strip through hole 221 and cooperates with the nail column 231 passing through the decorative strip through hole 221 to form an assembly unit. The assembly unit is formed in the accommodating cavity 222. The assembly unit does not contact the hole wall of the decorative strip through hole 221.

As shown in FIGS. 7 to 12 , the fastening sleeve 233 passes through the water-cut through hole 211 and then further passes through the connecting portion 2341 . When passing through the outer water-cut body 21 and the connecting portion 2341 , the nail column 231 does not directly contact either of them.

The connection part 2341 can be bonded, clamped or injection molded to the outer water-cut body 21. When the outer water-cut body 21 is replaced, the stopper 234 can be replaced together with the outer water-cut body 21.

Optionally, in some other embodiments, the connection portion 2341 is connected to the bright decorative strip 22, and the fastening sleeve 233 is partially inserted into the decorative strip through hole 221 (this solution is not shown in the figures).

More specifically, as shown in FIG. 2 and FIG. 4 , in one embodiment, the nail column 231 and the limiting portion 2342 are spaced apart to form an insertion hole 235 , the insertion direction of the insertion hole 235 is consistent with the axial direction of the nail column 231 , and the limiting portion 2342 is provided with a bayonet 2343 communicating with the insertion hole 235 ;

The nail column cap 232 includes a cap body 2322 and a cap column 2321 arranged in the cap body 2322 and connected to the cap body 2322. The cap column 2321 is provided with a plastically deformable hook 2323. The cap column 2321 can be inserted into the socket 235 and make the hook 2323 cooperate with the bayonet 2343. When the hook 2323 and the bayonet 2343 are misaligned, the hook 2323 is squeezed by the limiting portion 2342 and the nail column 231 and plastically deformed. When the hook 2323 and the bayonet 2343 are aligned, the hook 2323 is deformed and hooked in the bayonet 2343.

During the assembly process, the nail column 231 first passes through the through hole of one of the outer water-cut body 21 and the bright decorative strip 22 connected to the connecting portion 2341, thereby fixing the relative position between the nail column 231 and the limiting portion 2342 to form the insertion hole 235. Then, the outer water-cut body 21 and the bright decorative strip 22 are matched together, so that the nail column 231 passes through both the outer water-cut body 21 and the bright decorative strip 22, and then the cap column 2321 is inserted into the insertion hole 235 until the hook 2323 is hooked in the bayonet 2343. If the shape of the insertion hole 235 is not released, the hook 2323 cannot be withdrawn from the bayonet 2343.

Therefore, during disassembly, the nail column 231 needs to be removed first, so that the cap column 2321 can move relative to the limiting portion 2342, so that the hook 2323 exits the latch 2343, and then the outer water-cut body 21 and the bright decorative strip 22 are disassembled.

As shown in FIGS. 7 to 9, after the nail column 231 passes through the fastening sleeve 233, the relative position between the nail column 231 and the limiting portion 2342 is fixed, forming an assembly unit that can be detachably matched with the cap column 2321. As shown in FIG. 7, the cap column 2321 is first aligned with the opening of the socket 235, and then as shown in FIG. 8, the cap column 2321 is gradually inserted into the socket 235. During this process, the hook 2323 is squeezed by the limiting portion 2342 and the nail column 231 and undergoes plastic deformation. Until as shown in FIG. 9, the hook 2323 moves to a position opposite to the bayonet 2343, the hook 2323 recovers its deformation and hooks in the bayonet 2343, and the relative position between the nail column cap 232 and the nail column 231 is fixed.

As shown in FIG. 11 and FIG. 12 , during the disassembly process, the nail column 231 is first removed from the fastening sleeve 233 , and the cap column 2321 is freed from the constraint of the nail column 231 and can move relative to the limiting portion 2342 , so that the hook 2323 is freed from the latch 2343 .

In some embodiments, as shown in FIG. 10 , a limiting protrusion 2325 is further provided on the cap column 2321 . When the hook 2323 is located in the slot 2343 , the limiting protrusion 2325 protrudes outside the cap column 2321 along the spacing direction between the nail column 231 and the limiting portion 2342 and abuts against the nail column 231 or the limiting portion 2342 .

When the cap column 2321 is inserted into the socket 235 and the hook 2323 is hooked in the slot 2343, the cooperation between the hook 2323 and the slot 2343 limits the displacement between the nail column cap 232 and the nail column 231 in the axial direction of the nail column 231, and the setting of the limiting protrusion 2325 limits the displacement between the nail column 231 and the nail column cap 232 in the aforementioned spacing direction.

The outer diameter of the cap column 2321 is smaller than the hole diameter of the insertion hole 235, so when the hook 2323 is located in the latch 2343, there is a gap between the cap column 2321 and the hole wall of the insertion hole 235, and the cap column 2321 may shake in the insertion hole 235 in the above-mentioned spacing direction. The setting of the limiting protrusion 2325 effectively prevents the cap column 2321 from shaking relative to the insertion hole 235.

Further, as shown in FIG. 6 , FIG. 9 and FIG. 10 , in one embodiment, the cap column 2321 is connected to the middle of the cap body 2322, and the cap column 2321 is located in the space surrounded by the cap body 2322. A yielding inclined surface 2344 is provided on the limiting portion 2342 at one end close to the middle of the cap body 2322 along the insertion direction of the insertion hole 235, and the inclination trend of the yielding inclined surface 2344 is consistent with the inclination trend of the cap body 2322. When the cap column 2321 is gradually inserted into the insertion hole 235, the spacing between the yielding inclined surface 2344 and the cap body 2322 is gradually reduced, and the yielding inclined surface 2344 provides a yielding space to avoid interference between the cap body 2322 and the limiting portion 2342 and hinder the cap column 2321 from being inserted into the insertion hole 235.

As shown in FIG5 , the cap body 2322 is in an umbrella shape, with the middle part bulging outward, and the spacing defined by the brim 2324 is the maximum spacing H1. A certain cross section of the space enclosed by the cap body 2322 is an isosceles triangle, and the base of the isosceles triangle is defined by the brim 2324.

Further, as shown in FIG. 13 , in some embodiments, the outer water-cut body 21 is a long strip structure, the bright decorative strip 22 is a long strip structure, and the length directions of the outer water-cut body 21 and the bright decorative strip 22 are consistent. The outer water-cut body 21 is provided with a plurality of water-cut through holes 211, and the bright decorative strip 22 is provided with a plurality of decorative strip through holes 221, and the water-cut through holes 211 correspond to the decorative strip through holes 221 one by one, and each water-cut through hole 211 is sequentially arranged at intervals in the length direction of the outer water-cut body 21.

The outer water-cut assembly 20 includes a plurality of detachable nail column modules 23 , each of which is arranged in sequence and spaced apart along the length direction of the bright decorative strip 22 , and one detachable nail column module 23 corresponds to one water-cut through hole 211 and one decorative strip through hole 221 .

The accommodating cavity 222 is a long strip-shaped cavity, and the openings of the accommodating cavity 222 are located at two ends of the bright decorative strip 22 .

Furthermore, as shown in Figures 2 and 3, in some embodiments, the bright trim 22 is also provided with a long strip of slot 223, the length direction of the slot 223 is consistent with the length direction of the bright trim 22, and the two opposite slot walls of the slot 223 are provided with clip ribs 224 for snap-fitting on the door sheet metal 11.

An assembly notch 111 is provided on the door sheet metal 11 at a position for cooperating with the clamping rib 224 . When the bright trim strip 22 is assembled on the door sheet metal 11 , the edge of the door sheet metal 11 is located in the clamping groove 223 , and the clamping rib 224 is clamped in the assembly notch 111 .
