Description

Technical Field

[0001] This utility model relates to the field of frameless car door sealing technology, and in particular to a water-guiding structure for the upper corner of the snap-fit ​​strip of a split frameless car door. Background Technology

[0002] Frameless door sealing strips come in two frameless structures: split frameless and integral frameless. Integral frameless sealing strips only have a sealing surface at the frame joint and the outer watertight corner, resulting in a slightly weaker sealing effect. Split frameless sealing strips, depending on the installation location, employ either B-Pillar or C-Pillar structures. Both B-Pillar and C-Pillar structures have a first sealing surface at the outer watertight corner, and a second sealing surface between the frame and the outer watertight corner, resulting in a superior sealing effect. Therefore, split frameless sealing structures have indeed gained wider application due to their performance advantages.

[0003] Currently, the water guiding structure in the split-type frameless sealing structure is as shown in the instruction manual. Figure 1 and Figure 2 As shown, the snap-fit ​​strip body 1 is provided with a first connecting groove 11 and a second connecting groove 12. A corner lip 13 is provided between the first connecting groove 11 and the second connecting groove 12. A drainage hole 14 connecting the first connecting groove 11 and the second connecting groove 12 is provided at the corner lip 13. When processing the snap-fit ​​strip body, the limited position of the corner lip 13 results in a complex processing mold for the upper part of the snap-fit ​​strip body 1, leading to a high manufacturing cost for the snap-fit ​​strip body 1. At the same time, when demolding the snap-fit ​​strip body 1, the corner lip 13 forms a connection point A with the snap-fit ​​strip body 1. When the snap-fit ​​strip body 1 is removed, the connection point A is prone to bending and tearing, resulting in the scrapping of the snap-fit ​​strip body 1 and a high defect rate, which further increases the processing cost. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a water-guiding structure for the corner of a split frameless car door snap-fit ​​strip, which solves the problem that the connection point between the corner lip and the snap-fit ​​strip body is prone to tearing during demolding, resulting in a high defect rate and high processing cost of the snap-fit ​​strip body.

[0005] To achieve the above objectives, the basic solution of this utility model is as follows: A water-guiding structure for the upper corner of a split frameless car door snap-fit ​​strip, comprising a snap-fit ​​strip body, the snap-fit ​​strip body including an upper corner strip and a snap-fit ​​strip segment fixed to the lower side of the upper corner strip, the snap-fit ​​strip segment being provided with a first guide groove, the upper corner strip including: baffle; The first water-blocking lip is fixed to one side of the baffle. The second water-blocking lip is fixed to the top of the other side of the baffle. The first water-blocking lip, the second water-blocking lip and the surface of the baffle form a second guide channel that communicates with the first guide channel.

[0006] The technical principle of this utility model is as follows: when using a mold to manufacture the upper corner strip, no space is reserved for the corner lip in the mold. The first and second water-blocking lips are independently separated in the final formed state. When separating the upper corner strip from the mold, there is no longer a risk of tearing at the connection point A. At the same time, the separation of the first and second water-blocking lips from the mold is more efficient, the processing efficiency can be improved, and the manufacturing cost of the upper corner strip is reduced.

[0007] Compared to the first and second connecting channels in the prior art, the second guiding channel, formed by the first and second water-retaining lips and the baffle, has a larger space and area, which improves the guiding effect of rainwater and reduces the risk of water leakage at the top of the car window glass.

[0008] Furthermore, the snap-fit ​​segment includes: The snap-fit ​​strip body is fixedly connected to the baffle. The third water-blocking lip is fixedly connected to the lower end of the first water-blocking lip; The fourth water-blocking lip is fixedly connected to the lower end of the second water-blocking lip.

[0009] With the above configuration, the third water-blocking lip is directly and fixedly connected to the lower end of the first water-blocking lip, so that the rainwater guided by the first water-blocking lip can quickly enter the first guide channel, which can significantly improve the rainwater discharge efficiency.

[0010] Furthermore, the first water-retaining lip, the second water-retaining lip, and the baffle are integrally formed.

[0011] The above settings improve the overall integrity and durability of the upper corner strip, and make the water guiding fit between the first and second water-blocking lips more stable.

[0012] Furthermore, the third and fourth water-blocking lips are integrally formed with the snap-fit ​​strip body.

[0013] The above settings enhance the integrity and durability of the snap-fit ​​strip, making the fit between the third and fourth water-blocking lips and the first and second water-blocking lips more precise and stable.

[0014] Furthermore, at the end of the second water-retaining lip that is away from the fourth water-retaining lip, there is a clamping flange that abuts against the top of the window glass after it is raised.

[0015] With the above configuration, when the window glass moves up to the top, the abutting flange can abut against the raised window glass, thereby deforming the top of the abutting flange and the second water-blocking lip, which can abut against the edge of the window glass and improve the performance of preventing air and water leakage.

[0016] Furthermore, the vertical mounting height of the abutment flange is higher than the height of the upper edge of the door glass when the door glass is closed.

[0017] The above settings ensure that the clamping flange can fit snugly against the edge of the window glass, further improving the performance against air and water leakage.

[0018] Furthermore, the clamping flange is flared.

[0019] With the above configuration, the flared sealing flange can extend outward when subjected to force, thereby increasing the sealing range of the sealing flange on the top side of the window glass and reducing the risk of air and water leakage between the top side of the window glass and the second water-blocking lip.

Detailed Implementation

[0024] The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0025] This embodiment is basically as follows: Figure 3 As shown, this utility model embodiment proposes a water guiding structure for the upper corner of the snap-fit ​​strip of a split frameless car door, including a snap-fit ​​strip body, the snap-fit ​​strip body including an upper corner strip 102 and a snap-fit ​​strip segment 101 fixed to the lower side of the upper corner strip 102, and a first guide groove 141 is provided at the snap-fit ​​strip segment 101.

[0026] like Figure 3As shown, the upper corner strip 102 includes a baffle 112, a first water-blocking lip 122 and a second water-blocking lip 132. The first water-blocking lip 122 is arc-shaped and is fixed to the upper left side of the baffle 112. The second water-blocking lip 132 is vertically fixed to the top right side of the baffle 112. The first water-blocking lip 122, the second water-blocking lip 132 and the baffle 112 are integrally formed.

[0027] like Figure 3 As shown, the snap-fit ​​strip 101 includes a snap-fit ​​strip 101 body fixedly connected to the baffle 112, a third water-blocking lip 121, and a fourth water-blocking lip 131. The third water-blocking lip 121 and the fourth water-blocking lip 131 are integrally formed with the snap-fit ​​strip 101 body. The surface of the baffle 112 smoothly transitions with the surface of the snap-fit ​​strip 101 body. The third water-blocking lip 121 is fixedly connected to the lower end of the first water-blocking lip 122, and the surface of the third water-blocking lip 121 smoothly transitions with the surface of the first water-blocking lip 122. The fourth water-blocking lip 131 is fixedly connected to the lower end of the second water-blocking lip 132, and the surface of the fourth water-blocking lip 131 smoothly transitions with the surface of the second water-blocking lip 132.

[0028] like Figure 3 As shown, the first water-blocking lip 122, the second water-blocking lip 132 and the surface of the baffle 112 form a second guide channel 152 that communicates with the first guide channel 141.

[0029] At the same time, such as Figure 3 As shown, the upper end of the second water-blocking lip has an integrally formed abutting flange 142, which abuts against the edge of the raised window glass. The abutting flange 142 is flared. The vertical installation height of the abutting flange 142 is higher than the height of the upper edge of the door glass when the door glass is closed.

[0030] In addition, the vertical height L1 of the clamping flange 142 is 0.5 mm, and the horizontal outward expansion width L2 of the clamping flange 14220 is 0.2 mm.

[0031] In this embodiment, when manufacturing a water-guiding structure for the upper corner of a split frameless car door clip strip, the mold used for the upper corner strip 102 no longer reserves space for the corner lip. The first water-blocking lip 122 and the second water-blocking lip 132 are independently separated. When separating the upper corner strip 102 from the mold, there is no longer a risk of tearing at the connection point A. At the same time, the separation of the first water-blocking lip 122 and the second water-blocking lip 132 from the mold is more efficient, improving processing efficiency and reducing the manufacturing cost of the upper corner strip 102.

[0032] After installation on the vehicle, the first water-blocking lip 122, the second water-blocking lip 132, and the baffle 112 form a large-scale second guide channel 152. The second guide channel 152 can guide the water between the first water-blocking lip 122 and the second water-blocking lip 132 as a whole, improving the water diversion effect. At the same time, the second guide channel 152 can cooperate with the first guide channel 141 of the snap-fit ​​strip 101, so that the rainwater diverted by the first water-blocking lip and the second water-blocking lip 132 can be quickly discharged from the first guide channel 141. The rainwater discharge efficiency can be significantly improved, and the risk of water leakage at the top of the vehicle window can also be reduced.

[0033] When the window glass moves up to the top, the sealing flange 142 abuts against the raised window glass, causing the top of the sealing flange 142 and the second water-blocking lip 132 to deform. The flared sealing flange 142 can extend outward, increasing the sealing range of the sealing flange 142 on the top side of the window glass and reducing the risk of air and water leakage between the top side of the window glass and the second water-blocking lip 132.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
