Description

Technical Field

[0001] The utility model relates to the field of automobile parts, in particular to an automobile grille decorative strip. Background Art

[0002] In order to make the front face of the vehicle more sculptural and fashionable and improve the aesthetic degree, a decorative strip is installed on the grille base frame A of the automobile. The back of the decorative strip is connected to the grille base frame by screws; to improve the rigidity of the decorative strip or the convenience of connection, as Figure 1 shown, there are convex strips 2 at the edge of the back of the decorative strip 1, and a cross bridge 3 is spanned between the opposite convex strips 2. A threaded hole for connecting a screw is provided on the cross bridge 3. In view of the requirement of weight reduction design, the height of the convex strip 2 protruding from the back of the decorative strip 1 generally does not need to be too large, usually not exceeding 2 mm. Also due to the requirement of the shape, the heights of the convex strips 2 at both ends in the length direction of the decorative strip 1 are different. The height of the convex strip 2 at the low position end is only 1.18 mm. In this way, the space distance between the bottom of the flat cross bridge 3 and the back of the decorative strip 1 is only 1.18 mm, and the thickness of the angled ejector die when injection molding this part is also only 1.18 mm. The angled ejector die is easily broken during the demolding process. Not only does it need to be replaced in time, but it can only be implemented when the machine is stopped, which seriously affects the production effect. Summary of the Utility Model

[0003] The purpose of the utility model is to provide an automobile grille decorative strip, and improve the structure of its back to improve the service life of its injection molding die.

[0004] The utility model can be realized by the following technical solutions: an automobile grille decorative strip, there are strip-shaped protrusions at the edge of the back of the decorative strip, a cross bridge is spanned between the opposite strip-shaped protrusions, both ends of the cross bridge are connected to the top surface of the strip-shaped protrusions, a threaded column with a threaded hole inside is arranged in the middle of the cross bridge, the threaded column extends towards the side where the rear automobile grille base frame A is located, and the cross bridge is in a bow shape with both ends low and the middle high.

[0005] Compared with the prior art, the utility model has the following beneficial effects:

[0006] After the cross bridge is set to a bow shape, except for both ends of the cross bridge, the distance between other positions of the cross bridge and the plate surface of the decorative strip is greater than 1.18 mm of the original design. It not only ensures the normal setting of the cross bridge on the decorative strip, but also makes the thickness of the angled ejector die when injection molding this part greater than 1.18 mm. The angled ejector die is not easily broken during the demolding process, thus ensuring the continuous production and guaranteeing the production efficiency. Description of the Drawings

[0012] See also Figure 2-5 As shown, a decorative strip of an automobile grille has a strip protrusion 11 at the edge of the back side of the decorative strip 10, a bridge 12 is arranged between the strip protrusions 11 on opposite sides, both ends of the bridge 12 are connected to the top surface of the strip protrusion 11, a threaded column 13 with a threaded hole 131 is arranged in the middle of the bridge 12, the threaded column 13 extends to the side where the automobile grille base frame A is located at the rear, and the bridge 12 is an arch with low ends and high middle part;

[0013] The back of the decorative strip 10 is the side connected to the automobile grille base frame A. When installing the decorative strip 10, the strip-shaped protrusion 11 and the decorative strip 10 are embedded in the installation groove on the automobile grille base frame A, and the screw is screwed into the threaded hole 131 in the threaded column 13 to realize the connection between the automobile grille base frame A and the decorative strip 10; after the bridge 1 is set to an arch shape, except for the two ends of the bridge 12, the distance between the other positions of the bridge 12 and the board surface of the decorative strip 10 is greater than the original design of 1.18mm. In this embodiment, the distance between the highest position of the bridge 12 and the board surface of the decorative strip 10 is 3mm, which not only ensures the normal setting of the bridge 12 and the screw column 13 on the decorative strip 10, but also makes the thickness of the inclined top mold when injection molding this part greater than 1.18mm, so that the inclined top mold is not easy to break during the demolding process, which not only improves the service life of the inclined top mold, but also ensures the continuous production and production efficiency.

[0014] The bridge 12 is in the shape of an arc with an opening facing downward or in the shape of an expanded groove with a flat top facing downward; the top surfaces at both ends of the bridge 12 are flush and extended with the top surfaces of the strip-shaped protrusions 11; when the thickness of the bridge 12 remains unchanged, the distance between the two ends of the bridge 12 and the board surface of the decorative strip 10 is still 1.18 mm as originally designed. Since the end surfaces at both ends of the bridge 12 are completely connected to the strip-shaped protrusions 11, the strip-shaped protrusions 11 support the bridge 12, which is beneficial to ensure the structural strength after the two are connected.

[0015] A snap-in plate 14 is provided on the strip-shaped protrusion 11 in the length direction of the decorative strip 10; a connecting hole 141 is opened on the surface of the snap-in plate 14; when installing the decorative strip 10, after the decorative strip 10 and the strip-shaped protrusion 11 are embedded in the installation groove on the automobile grille base frame A, the snap-in plate 14 is also inserted into the corresponding snap-in hole on the automobile grille base frame A, thereby enhancing the stability of the connection between the snap-in plate 14 and the automobile grille base frame A.

[0016] A positioning step 111 is provided on the strip-shaped protrusion 11; when the positioning step 111 contacts with the automobile grille base frame A, it is a point contact, and the contact area between the positioning step 111 and the automobile grille base frame A is small, which ensures that the back side of the decorative strip 10 can contact with the automobile grille base frame A while saving materials.

[0017] A reinforcing rib 132 extending in the axial direction is provided on the outer peripheral surface of the screw column 13, and one side of the reinforcing rib 132 is connected to the outer side of the bridge 12; the reinforcing rib 132 can significantly improve the overall strength and rigidity of the screw column 13, can resist external loads to a certain extent, and reduce deformation caused by bending or compression.

[0018] The reinforcing rib 132 is arranged on the circumferential surface of the screw column 13, and the extension surface of the reinforcing rib 132 extends to the intersection of the strip protrusion 11 and the side of the bridge 12; due to the stress concentration at the intersection of the strip protrusion 11 and the side of the bridge 12, the structural strength at this position is reduced. By setting the extension surface of the reinforcing rib 132 to extend to the intersection of the strip protrusion 11 and the side of the bridge 12, it is beneficial to enhance the structural strength at this position;

[0019] There are two or four reinforcing ribs 132; there are four intersections between the strip protrusion 11 and the side of the bridge 12. If two reinforcing ribs 132 are provided, the reinforcing ribs 132 should be provided at the intersections between the strip protrusion 11 and the side of the bridge 12 on the opposite side to ensure that the structural strength of both ends of the bridge 12 is strengthened. Two or four reinforcing ribs 132 are provided to strengthen the strength of the weak part of the connection between the bridge 12 and the strip protrusion 11.

[0020] The height of the strip-shaped protrusions 11 at both ends of the decorative strip 10 in the length direction is high at one end and low at the other end, and there is a smooth transition between the two ends; the setting of the protrusion height of the strip-shaped protrusions 11 is used to meet the requirements of the shape of the decorative strip 10.
