Description

Technical Field

[0001] The present invention belongs to the technical field of automotive outer water cut-offs, and particularly relates to an end cap for cooperating with an aluminum bright strip of an outer water cut-off. Background Art

[0002] Since the outer water cut-off is exposed outside the vehicle window and serves both as a seal and an exterior decorative part, it has relatively high appearance requirements. Currently, most outer water cut-offs with end caps are made of stainless steel. In order to achieve good appearance at both ends of the outer water cut-off and good fixation with the sheet metal at the end, more and more aluminum bright strip outer water cut-offs are also using end caps. The existing structures of the exposed ends of aluminum bright strip outer water cut-offs are all flanged structures of the aluminum bright strip. The main body is mostly formed by direct punching or injection molding at both ends of the main body. The appearance of the cooperation between the positioning end main body and the aluminum bright strip flange can be guaranteed, but the appearance of the non-positioning end is not very good because there is a large deviation in the length direction between the non-positioning end main body and the bright strip. In addition, there are usually punching notches at the end of the outer water cut-off, and the vehicle door sheet metal has also become a single-layer board. The clamping force of the outer water cut-off on the sheet metal at the end is relatively small, and the fixation between the end of the outer water cut-off and the sheet metal is not firm enough. For some aluminum bright strip outer water cut-offs with end caps, there are generally problems such as difficult assembly between the end cap and the aluminum bright strip of the outer water cut-off and too small connection force, resulting in the end cap being easily detached from the aluminum bright strip of the outer water cut-off. Once the end cap falls off, the function of the end cap cannot be realized, and it has an adverse impact on the vehicle appearance. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide an end cap for cooperating with an aluminum bright strip of an outer water cut-off in view of the current situation of the prior art, which can solve the problems of difficult assembly of the end cap of the aluminum bright strip outer water cut-off and easy falling off after assembly, and can ensure simple assembly of the end cap and facilitate automated assembly.

[0004] The technical solution adopted by the present invention to solve the above technical problems is as follows: An end cap for cooperating with an aluminum bright strip of an outer water cut-off is installed at the end of the bright strip. The bright strip has an upper side rib, a middle rib, and a lower side rib. The end cap is characterized in that it includes a main body. At least one end cap fixing rib capable of cooperating with the upper side rib and the middle rib is provided at the lower part of the main body. An upper side fixing rib is provided at the upper part of the main body. The upper side fixing rib cooperates with the upper side rib of the bright strip. The end cap fixing rib and the upper side fixing rib cooperate with the bright strip to form the cooperation between the end cap and the bright strip in the YZ direction. A positioning and limiting rib is provided beside the end cap fixing rib, and a fixing notch is opened at the lower side rib. The positioning and limiting rib cooperates with the fixing notch of the bright strip to form the limiting cooperation between the end cap and the bright strip in the X direction.

[0005] As a way, in the end cap matched with the above external water cut aluminum bright strip, there are two end cap fixing ribs, including a first end cap fixing rib and a second end cap fixing rib. The first end cap fixing rib has a first upper clamping rib and a first lower clamping rib on the end cap, and the second end cap fixing rib has a second upper clamping rib and a second lower clamping rib on the end cap. Elastic grooves are formed on the first end cap fixing rib and the second end cap fixing rib, and the positioning and limiting rib is located between the first end cap fixing rib and the second end cap fixing rib.

[0006] In the end cap matched with the above external water cut aluminum bright strip, first avoidance notches and second avoidance notches are respectively formed on the middle rib. The first upper clamping rib on the end cap falls into the first avoidance notch and can move to the middle rib, and the second upper clamping rib on the end cap falls into the second avoidance notch and can move to the middle rib. The end cap moves backward a certain distance until the positioning and limiting rib of the end cap falls into the fixing notch of the bright strip.

[0007] In the end cap matched with the above external water cut aluminum bright strip, the upper side fixing rib is located at the side end of the upper part.

[0008] In the end cap matched with the above external water cut aluminum bright strip, there is a abutting chuck on the inner side surface of the body.

[0009] As another way, in the end cap matched with the above external water cut aluminum bright strip, the end cap has a crescent notch. There are two end cap fixing ribs, including a first end cap fixing rib and a second end cap fixing rib. The first end cap fixing rib has a first upper clamping rib and a first lower clamping rib on the end cap, and the second end cap fixing rib has a second lower clamping rib on the end cap. Elastic grooves are formed on the first end cap fixing rib and the second end cap fixing rib, and the positioning and limiting rib is located between the first end cap fixing rib and the second end cap fixing rib.

[0010] In the end cap matched with the above external water cut aluminum bright strip, the end cap has a flanging support edge, the bright strip has a flanging, and the body has an end cap positioning boss. The flanging support edge is located inside the flanging, and the end cap positioning boss is matched with the inner side surface of the flanging of the bright strip.

[0011] In the end cap matched with the above external water cut aluminum bright strip, the upper side fixing rib is located on the upper side edge.

[0012] Compared with the prior art, the advantages of the present invention are that it solves the problems that it is difficult to assemble the external water cut end cap of the aluminum bright strip and it is easy to fall off after assembly, and it can ensure that the assembly of the end cap is simple and it is convenient to realize automatic assembly.

[0020] Embodiment 1

[0021] As Figure 1 and Figure 2As shown, the end cap that mates with the outer water cut aluminum bright strip is installed at the end of the bright strip 21. The bright strip 21 has an upper side rib 1, a middle rib 2, and a lower side rib 3. The material and mechanical properties of the aluminum bright strip can be based on customer requirements. If there are no special requirements, the end cap material can be hard plastics such as POM, PP-T20, and ABS according to customer needs. The end cap includes a body 4. At least one end cap fixing rib that can cooperate with the upper side rib 1 and the middle rib 2 is provided at the lower part of the body 4. An upper side fixing rib 5 is provided at the upper part of the body 4. The upper side fixing rib 5 cooperates with the upper side rib 1 of the bright strip 21. The upper side fixing rib 5 is located at the side end of the upper part. An abutting chuck 6 is provided on the inner side surface of the body 4. Here, the bright strip 21 is supported by the abutting chuck 6 to prevent the bright strip 21 from collapsing. Here, there are two end cap fixing ribs, including a first end cap fixing rib 7 and a second end cap fixing rib 8. The first end cap fixing rib 7 has a first upper end cap rib 9 and a first lower end cap rib 10. The second end cap fixing rib 8 has a second upper end cap rib 11 and a second lower end cap rib 12. An elastic groove 13 is formed on the first end cap fixing rib 7 and the second end cap fixing rib 8. A positioning and limiting rib 14 is located between the first end cap fixing rib 7 and the second end cap fixing rib 8. Here, the elastic groove 13 makes each end cap fixing rib more elastic. A positioning and limiting rib 14 is provided beside the end cap fixing rib. A fixing notch 15 is opened at the lower side rib 3. A first avoiding notch 16 and a second avoiding notch 17 are respectively opened on the middle rib 2. The first upper end cap rib 9 falls into the first avoiding notch 16 and can move to the middle rib 2. The second upper end cap rib 11 falls into the second avoiding notch 17 and can move to the middle rib 2. The end cap moves backward a certain distance until the positioning and limiting rib 14 of the end cap falls into the fixing notch 15 of the bright strip 21.

[0022] The first lower end cap rib 10 and the second lower end cap rib 12 cooperate with the lower side rib 3 of the bright strip 21. The first upper end cap rib 9 and the second upper end cap rib 11 cooperate with the middle rib 2 of the bright strip 21. The upper side fixing rib 5 of the end cap cooperates with the upper side rib 1 of the bright strip 21, forming a firm and reliable cooperation between the end cap and the bright strip 21 in the YZ direction. The positioning and limiting rib 14 of the end cap cooperates with the fixing notch 15 of the bright strip 21, forming a reliable cooperation between the end cap and the bright strip 21 in the X direction. Since the first lower end cap rib 10, the second lower end cap rib 12, the first upper end cap rib 9, the second upper end cap rib 11, and the upper side fixing rib 5 are all relatively thick, they can provide a relatively large connection force, making it difficult for the end cap to fall off the bright strip 21. And the upper side fixing rib 5 can ensure that the gap between the upper side of the end cap and the bright strip 21 will not be too large after matching, thus providing a better appearance effect.

[0023] During the end cap assembly process, first move the end cap forward by a certain distance. At this time, the first end cap fixing rib 7 aligns with the first avoidance notch 16, and the second end cap fixing rib 8 aligns with the second avoidance notch 17. Then place the end cap on the bright strip 21, so that the first lower clamping rib 10 of the end cap and the second lower clamping rib 12 of the end cap match the lower side rib 3 of the bright strip 21. The first end cap fixing rib 7 falls into the first avoidance notch 16 of the bright strip 21, and the second end cap fixing rib 8 falls into the second avoidance notch 17 of the bright strip 21. Finally, move the end cap backward by a certain distance until the positioning and limiting rib 14 of the end cap falls into the bright strip fixing notch 15. At this time, the upper side fixing rib 5 of the end cap also matches the upper side rib 1 of the bright strip 21 at the same time, and the end cap assembly is completed. During the assembly process, the end cap positioning and the positioning and limiting rib 14 will be deformed by force and return to their original shape after falling into the fixing notch 15 of the bright strip 21. The above is the assembly method of the end cap with a crescent. First, move the end cap backward by a certain distance along the length direction of the outer water cut, then place the end cap on the bright strip 21, and finally move the end cap forward by a certain distance to the final assembly position.

[0024] Embodiment 2

[0025] As Figure 3 , Figure 4 and Figure 5 shown, most of the structures of this Embodiment 2 are the same as those of Embodiment 1. The end cap has a crescent notch, and there are two end cap fixing ribs, including the first end cap fixing rib 7 and the second end cap fixing rib 8. The first end cap fixing rib 7 has a first upper clamping rib 9 and a first lower clamping rib 10 of the end cap. The second end cap fixing rib 8 has a second lower clamping rib 12 of the end cap. Elastic grooves 13 are formed on the first end cap fixing rib 7 and the second end cap fixing rib 8. The positioning and limiting rib 14 is located between the first end cap fixing rib 7 and the second end cap fixing rib 8. The end cap has a flanging support edge 18. There is a flanging 19 on the bright strip 21, and there is an end cap positioning boss 20 on the body 4. The flanging support edge 18 is located inside the flanging 19, and the end cap positioning boss 20 cooperates with the inner side surface of the flanging 19 of the bright strip 21.

[0026] The lower clamping ribs 10 of the first end cover and the lower clamping ribs 12 of the second end cover cooperate with the lower side ribs 3 of the bright strip 21, and the upper fixing ribs 5 of the end cover cooperate with the upper side ribs 1 of the bright strip 21 to form a firm and reliable cooperation between the end cover and the bright strip 21 in the YZ direction. The positioning boss 20 of the end cover cooperates with the flanging 19 of the bright strip 21 to form an X-direction positioning of the end cover on the bright strip 21. The positioning and limiting rib 14 of the end cover cooperates with the first limiting notch of the bright strip 21 to form an X-direction limit of the end cover on the bright strip 21. Since the upper clamping rib 9 of the first end cover, the lower clamping rib 10 of the first end cover, the lower clamping rib 12 of the second end cover, and the upper fixing rib 5 are all relatively thick, they can provide a relatively large connection force, making it difficult for the end cover to fall off the bright strip 21. The positioning boss 20 of the end cover directly cooperates with the inner side surface of the flanging 19 of the bright strip 21, making it easier to control the X-direction step difference between the end cover and the bright strip 21. The end cover fixing rib is relatively close to the upper side outer surface of the end cover, which can provide a relatively large pull-off force to prevent the end cover from being pressed and collapsed here. Finally, a better cooperation effect between the end cover and the aluminum bright strip is provided.

[0027] During the end cover assembly process, first move the end cover forward by a certain distance. At this time, the first end cover fixing rib 7 is aligned with the first avoidance notch 16 of the bright strip 21, and the second end cover fixing rib 8 is aligned with the second avoidance notch 17 of the bright strip 21. Then place the end cover on the bright strip 21 so that the lower clamping ribs 10 of the first end cover and the lower clamping ribs 12 of the second end cover match the lower side ribs 3 of the bright strip 21. The first end cover fixing rib 7 falls into the first avoidance notch 16 of the bright strip 21, and the second end cover fixing rib 8 falls into the second avoidance notch 17 of the bright strip 21. Finally, move the end cover backward by a certain distance until the positioning boss 20 of the end cover contacts the inner side surface of the flanging 19 of the bright strip 21. At this time, the positioning and limiting rib 14 falls into the fixing notch 15 of the bright strip 21, and the end cover assembly is completed. During the assembly process, the positioning and limiting rib 14 will be deformed by force and then return to its original shape after falling into the fixing notch 15. Here, the end cover is assembled by moving from the inside of the outer water cut to the outside.

[0028] The specific embodiments described in this article are only examples to illustrate the spirit of the present invention. Those skilled in the art of the present invention can make various modifications, supplements, or use similar methods to replace the described specific embodiments, but will not deviate from the scope defined by the spirit of the present invention.
