Description

Technical Field

[0001] The utility model relates to the technical field of automobile accessories, in particular to a lower clip strip structure of a front windshield. Background Art

[0002] Since the dawn of the automotive industry, windshield clips have played a key role. Early designs primarily focused on connectivity and basic sealing performance. However, with technological advancements and rising demands for environmental protection, comfort, and safety, the functional requirements of windshield clips have evolved. To adapt to the overall performance improvements of buses, researchers analyzed the development trends of the windshield clip industry from the perspectives of materials, structure, and production technology. While market trends primarily focus on connectivity, partial sealing, and decorative features, they often overlook the issue of slot deformation during transportation. As bus upgrades, the structure and materials of windshield clips have undergone innovation.

[0003] The lower clip strip of the front windshield connects the front windshield glass and the cover plate. In order to protect the groove from deformation during transportation, a through-root insert is usually installed. The insert serves to protect the slot of the clip from deformation. However, before the windshield glass and the cover plate arrive at the OEM and the cover plate is installed, the operator needs to tear off the insert first, which increases the installation process and the workload of the workers in assembly.

[0004] In existing technology, clip strips are widely used to connect the grille to the windshield. However, these clip strips fail to protect the clip strips from deformation during transportation. To minimize material waste, reduce installation steps, lower assembly costs, and improve work efficiency, a clip strip structure for the windshield underside that protects the clip strips is urgently needed. Summary of the Invention

DETAILED DESCRIPTION

[0031] The following is a further detailed description of the embodiments of the present invention in conjunction with the accompanying drawings and examples. The detailed description of the following examples and the accompanying drawings are used to illustrate the principles of the present invention, but are not intended to limit the scope of the present invention. That is, the present invention is not limited to the preferred embodiments described, and the scope of the present invention is defined by the claims.

[0032] In the description of this utility model, it should be noted that, unless otherwise specified, "plurality" means two or more. Furthermore, terms such as "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance. The terms "mounted" and "connected" should be interpreted broadly, for example, to mean fixed, removable, or integral; mechanical or electrical; direct or indirect through an intermediary. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0033] See also Figure 1 and Figure 2As shown, a front windshield lower clip structure includes a U-shaped groove 1 and a strip 2. The U-shaped groove 1 connects the strip 2. The U-shaped groove 1 includes a curved arm 11 and a first straight arm 12 and a second straight arm 13 disposed at either end of the curved arm 11. A first buffer 14 is disposed outside the connection between the first straight arm 12 and the curved arm 11. The cross-sectional shape of the first buffer 14 is one of square, rectangular, triangular, elliptical, regular polygonal, and irregular polygonal. One end of the second straight arm 13 connects the U-shaped groove 1 and the strip 2.

[0034] Particularly noteworthy is that the inner side of the second straight arm 13 is a relatively inclined, smoothly transitional curved surface. A first buffer slope 131 is provided on the outer side of the connection between the U-shaped groove 1 and the strip 2. The first buffer slope 131 is relatively flat relative to the inner angle between the second straight arm 13 and the curved arm 11. The first buffer slope 131 is partially or entirely provided on the outer side of the second straight arm 13, and the angle between the first buffer slope 131 and the outer bottom edge of the curved arm 11 is between 95° and 175°. By providing the first buffer member 14 in conjunction with the first buffer slope 131, the present invention cushions and absorbs forces applied to the windshield during transportation. Thus, even without the use of a molding, the notch can be protected, ensuring safe transportation of the windshield, resolving the problem of deformation of the windshield notch during transportation, and simplifying the installation process for assemblers.

[0035] In practice, the U-shaped groove and the strip are integrally formed. A metal frame is provided within both the strip and the U-shaped groove. This metal frame helps strengthen the support structure of the clip strip, making it less susceptible to damage and extending the life of the clip strip. The clip strip is typically extruded from a mixture of plastic and aluminum strip. Those skilled in the art will appreciate that, in addition to using a metal frame, an alloy frame or other frame with a certain degree of hardness can also be used as a support. The clip strip can be made of one or more of rigid PVC or PP, which will not be further described here. A first soft structure 132 is also provided on the inner side of the second straight arm 13. The first soft structure is extruded by an extrusion process. The first soft structure is made of TPE material. Part or all of the first soft structure 132 is provided inside the card strip body and is connected to the card strip body. A through hole is provided at one end of the first soft structure 132 close to the curved arm. The through hole is elliptical. The first soft structure 132 is extruded by an extrusion process. Preferably, a wear-resistant layer 121 is also provided at the end of the first straight arm 12. The wear-resistant layer has a smooth shape, which is convenient for direct or indirect overlap connection with the hand piece cover. The material of the wear-resistant layer 121 is TPE with a relatively large friction coefficient. From the above description, it can be seen that in this structure, the first buffer cooperates with the first buffer slope to provide buffering protection for the front windshield notch to prevent deformation of the front windshield notch. The overall structure is simple, the material is common, the cost is low, and it has both the function of a card strip and the function of an insert. Therefore, it is suitable for mass production and promotion in the market.

[0036] See Figure 3 As shown, the front windshield with the prior art CN221316030 U clip is placed in the fixing groove 3 of the windshield transport device, as shown in FIG. Figure 3 As shown, the front windshield installed with the existing clip strip needs to insert the molding strip 4 into the U-shaped groove during transportation to ensure that the groove does not deform, and the front windshield clip strip in the prior art is not provided with an absorbent or buffering member. Therefore, during the bumpy transportation, it is impossible to ensure that the shape of the groove is not deformed by external forces.

[0037] See Figure 4As shown, it is a schematic diagram of placing the windshield installed with the present invention vertically in the fixed groove 3 on the windshield transport device during transportation of the front windshield, a front windshield lower clamping strip structure, including a U-shaped groove 1 and a strip member 2, the U-shaped groove 1 connecting the strip member 2, the U-shaped groove 1 including a curved arm 11 and a first straight arm 12 and a second straight arm 13 arranged at both ends of the curved arm 11, a first buffer member 14 is provided on the outside of the connection between the first straight arm 12 and the curved arm 11, the cross-sectional shape of the first buffer member 14 is a rounded square, during transportation, when the front windshield 5 is placed vertically in the groove 3 of the revolver, when the front windshield slot is subjected to force, the first buffer member and the first buffer slope absorb and buffer the force of this structure. One end of the second straight arm 13 connects the U-shaped groove 1 and the strip 1. The inner side of the second straight arm 13 is a relatively inclined smooth transitional curved surface. A first buffer slope 131 is also provided on the outer side of the second straight arm 13. The first buffer slope 131 is relatively gentle relative to the inward inclination angle of the second straight arm 13 and the curved arm 11. The first buffer slope 131 is partially or entirely provided on the outer side of the second straight arm 13. The angle between the first buffer slope 131 and the outer bottom edge of the curved arm 11 is 95° to 175°. The U-shaped groove and the strip are integrally formed. Metal frames are provided in both the strip and the U-shaped groove. In this embodiment, the card strip is extruded as a mixed extrusion of plastic and aluminum strip, which is relatively simple to produce and has both softness and toughness. A first soft structure is also provided on the inside of the second straight arm 13. The first soft structure is made of TPE and has a through-hole at one end near the curved arm. The first soft structure is extruded. The through-hole at the first end of the first soft structure causes the first end of the clip to deform as it enters the U-shaped groove, facilitating its insertion. Once the clip is inserted into the U-shaped groove, the first soft structure also deforms as it slides outward, preventing it from slipping out and preventing it from slipping out. The end of the first straight arm 12 is also provided with a wear-resistant layer 121. This smooth, rounded shape facilitates direct or indirect connection with the handpiece cover. The wear-resistant layer 121 is made of TPE, which has a high friction coefficient. As can be seen from the above embodiment, the first soft structure 132, in conjunction with the wear-resistant layer 121, can also absorb and cushion forces when the windshield is tilted forward.

[0038] See also Figure 5As shown, the windshield glass installed with this structure is placed at an angle within the revolver groove 3. The first buffer member 14 and the first buffer slope 131 absorb and buffer the force applied to the structure. The lower clip of the windshield of this device tilts backward, and the bottom edge of the U-shaped groove coincides with the same arc as the groove. Furthermore, when the structure continues to tilt backward, the first buffer member 14 and the first buffer slope 131 can absorb the force, thus protecting the notch from deformation. As shown in the figure, the windshield glass 5 using this structure does not need to be installed with the molding strip 4 when transporting. This not only ensures that the windshield notch does not deform due to force during transportation, but also reduces assembly and material costs, further improving the efficiency of windshield assembly.
