Problems solved by technology

However, such a traditional solution has a large investment in parts cost, equipment investment and installation man-hours.
On the other hand, in the middle and low-end models, due to cost control considerations, there is generally no head seal, which may cause large wind noise and abnormal vibration when the vehicle is driving.

Embodiment Construction

[0011] In order to better understand the technical solution of the present invention, it will be described in detail below through specific embodiments in conjunction with the accompanying drawings:

[0012] Such as figure 1 Shown, a kind of rigid skeleton guide channel top bar of the present invention comprises a rigid skeleton guide channel top bar body 3 with a side opening, and is arranged on the top surface of the hard skeleton guide channel top bar body 3, and is connected with The first upper clamping part 1 and the second upper clamping part 2 of the rigid skeleton guide groove top strip body 3 are axially parallel.

[0013] The first upper clamping part 1 is located on the closed side of the top bar body 3 of the rigid framework guide groove, and the second upper clamping part 2 is located on the opening side of the top bar body 3 of the rigid framework guide groove.

[0014] The first upper clamping part 1 is a lip made of semi-solid rubber and semi-sponge rubber, t...

Abstract

The invention relates to a hard framework guide slot top strip. The hard framework guide slot top strip comprises a hard framework guide slot top strip body with an opening in the lateral direction, a first upper clamping part and a second upper clamping part. The first upper clamping part and the second upper clamping part are located on the top face of the hard framework guide slot top strip body and are parallel to the axial direction of the hard framework guide slot top strip body. The first upper clamping part is located on the sealed side of the hard framework guide slot top strip body and is a semi-solid-rubber semi-sponge-rubber lip. The part, facing the open side, of the lip is made of solid rubber, and the part, opposite to the open side, of the lip is made of sponge rubber. The second upper clamping part is located on the open side of the hard framework guide slot top strip body and is a fin-shaped hollow sponge foam pipe parallel to the axial direction of the hard framework guide slot top strip body. Due to the design, abnormal friction sounds generated by connection of the top strip structure and a vehicle body in the vehicle running process are reduced, air noise is lowered, and the sealing performance of a system without a first sealing strip is achieved.

Description

technical field [0001] The invention relates to the field of seals for automobiles, in particular to a top strip of a hard skeleton guide groove. Background technique [0002] At present, the contact seal between the top strip of the guide groove and the body in China generally adopts the form of two small lips, and at the same time, the first sealing strip is assembled on the inner lip to improve the overall sealing performance. However, such a traditional solution has a large investment in parts cost, equipment investment and installation man-hours. In the middle and low-end models, due to cost control considerations, the head seal is generally not installed, which may cause relatively large wind noise and abnormal vibration during the driving process of the vehicle. How to design a reasonable sealing structure, reduce wind noise and vibration, improve vehicle sealing performance, and enhance the competitiveness of automobile manufacturers to enhance the competitiveness o...
