AI Technical Summary
The structure of existing automotive paint parts cannot meet the normal hanging point requirements, resulting in additional trimming processes and the use of auxiliary materials, increasing working hours and parts scrap rate.
A new hand-tearable hanging point structure is designed, including a plastic exterior trim and a hanging ear plate. The hanging ear plate is provided with a second hanging hole and a bevel with an included angle of 50°. The side wall of the hanging ear plate is flush with the side wall of the exterior trim, and notches are provided at both ends of the hanging ear plate to facilitate hand-tear operations and reduce the trimming process and the use of auxiliary materials.
On the premise of ensuring the strength of the hanging point structure, the hanging point structure is torn by hand to avoid scrapping of parts, reduce the number of processes and auxiliary materials used, reduce costs, and alleviate complaints from factory employees.

Abstract
Description
Technical Field
[0001] The utility model relates to the field of automobile plastic spraying products, in particular to a novel hand-tearable hanging point structure. Background Art
[0002] Many automotive exterior parts are now painted. Due to styling limitations, some painted parts lack the structural requirements for normal mounting points, necessitating the addition of new mounting points. However, if mounting points cannot be found within the existing structure, adding new mounting points requires an additional trimming step, wasting labor and materials (knives), and can easily lead to factory complaints and increased part scrap rates.
[0003] Therefore, it is necessary to provide a novel hand-tearable hanging point structure to solve the above technical problems. Utility Model Content
[0004] In order to solve the above technical problems, the utility model provides a novel hand-tearable hanging point structure.
[0005] The utility model provides a novel hand-tearable hanging point structure, comprising a plastic exterior trim and a hanging ear plate integrally arranged at the edge of the plastic exterior trim, wherein a first hanging hole is provided on the plastic exterior trim, a second hanging hole is provided at the center of the hanging ear plate, a bevel is provided at the connection between the plastic exterior trim and the hanging ear plate, the bevel is √-shaped, the bevel has an included angle of °, the thickness of the hanging ear plate at the bevel is less than the thickness of the rest of the part, the side wall of the hanging ear plate is flush with the side wall of the plastic exterior trim, and notches are provided at both ends of the plastic exterior trim facing the hanging ear plate.
[0006] Preferably, the hanging ear plate is quadrilateral, and a first chamfered corner is provided at the edge corner of the hanging ear plate.
[0007] Preferably, a second rounded corner is provided at the edge of the hanging ear plate.
[0008] Preferably, the distance between the edge of the second hanging hole and the edge of the hanging ear plate is ≧6 mm, and the diameter of the second hanging hole is 8 mm.
[0009] Preferably, the thickness of the connection between the exterior trim and the suspension ear plate is 1.2 mm.
[0010] Compared with the related art, the present invention has the following beneficial effects:
[0011] By adding a hand-tearable hanging point (hanging lug), while ensuring the structural strength of the hanging point, the hanging point (hanging lug) can be directly torn off during the appearance inspection in the painting area. If the product is supplied as a single piece, it can be directly packed and shipped. If the assembly is required, the hanging point can be cut off during the assembly process without a knife. This can not only avoid the scrapping of parts due to trimming errors, reducing the scrap rate, but also eliminate a process and excess labor hours, and reduce the use of auxiliary materials (knives), reducing costs while alleviating factory employee complaints.

[0016] The present invention will be further described below with reference to the accompanying drawings and implementation examples.
[0017] Please refer to Figures 1 to 3 A new type of hand-tearable hanging point structure includes a plastic exterior trim 1 and a hanging ear plate 2 integrally arranged at the edge of the plastic exterior trim 1, the plastic exterior trim 1 is provided with a first hanging hole 7, and a second hanging hole 3 is provided at the center of the hanging ear plate 2. The connection between the plastic exterior trim 1 and the hanging ear plate 2 is provided with an oblique opening 4, the oblique opening 4 is √-shaped, and the angle of the oblique opening 4 is 50°. The thickness of the hanging ear plate 2 at the oblique opening 4 is less than the thickness of the rest of the part. The side wall of the hanging ear plate 2 is flush with the side wall of the plastic exterior trim 1, and notches 8 are provided at both ends of the plastic exterior trim 1 facing the hanging ear plate 2.
[0018] like Figure 1 The current solution adds a first hanging hole 7. The hanger is first inserted into the first hanging hole 7 to fix the Z and X directions; then the second hanging hole 3 is inserted to fix the XYZ directions; the parts can be fixed on the hanger steadily and without shaking, and the spraying effect is better.
[0019] After painting is complete, when the trolley reaches the next inspection area, the hanging lugs 2 can be manually torn off for appearance inspection. Tear spaces are reserved on both sides of the hanging lugs 2, making it easy to bend and tear the hanging points. This avoids the use of a knife, which can cause scratches and product scrapping due to knife misuse. It also reduces the number of steps required. During painting, the hanging points (hanging lugs 2) can be trimmed and shipped directly without further trimming. This also reduces the need for auxiliary materials (knives). The first hanging hole 7 is a component assembly structure and does not require trimming.
[0020] The hanging ear plate 2 is quadrilateral, and a first rounded corner 5 is provided at the corner of the hanging ear plate 2 to prevent workers from being scratched.
[0021] The edge of the hanging ear plate 2 is provided with a second rounded corner 6 to prevent workers from being scratched.
[0022] The distance between the edge of the second hanging hole 3 and the edge of the hanging ear plate 2 is ≥6mm, and the diameter of the second hanging hole 3 is 8mm to prevent breakage due to insufficient strength. Paint will accumulate on the hanger column due to multiple painting. If the hole diameter is too small, it is necessary to frequently clean the accumulated paint, wasting work time.
[0023] The thickness of the connection between the exterior trim and the hanging ear plate 2 is 1.2 mm, which makes it easy to tear off the hanging ear plate 2.
[0024] The above description is merely an embodiment of the present invention and does not limit the patent scope of the present invention. Any equivalent structure or equivalent process transformation made by using the contents of the description and drawings of the present invention, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
