Description

Technical Field

[0001] This invention relates to the field of automotive plastic parts technology, specifically a lightweight, impact-resistant automotive injection molded part. Background Technology

[0002] Automotive injection molded parts refer to components manufactured for automobiles using the injection molding process. Here is some information about automotive injection molded parts: I. Characteristics: Lightweight: Injection molded parts are typically made of plastic, making them lighter than metal parts. This helps reduce the overall weight of the vehicle and improves fuel economy. High Cost-Effectiveness: Injection molding has high production efficiency and relatively low cost, allowing for large-scale production to meet the high-volume demands of the automotive industry. Design Flexibility: Injection molded parts of various complex shapes can be manufactured according to different automotive design requirements, satisfying the aesthetic and functional needs of the vehicle. Good Corrosion Resistance: Plastics have good corrosion resistance, enabling them to be used in various harsh environments and extending the service life of automotive parts. II. Application Areas: Interior Parts: Such as dashboards, center consoles, door panels, seat components, etc. These injection molded parts must not only meet aesthetic and comfort requirements but also possess certain strength and durability. Exterior Parts: Such as bumpers, headlight housings, rearview mirror housings, etc. These components need to have good weather resistance and impact resistance to ensure the safety of the vehicle during driving.

[0003] To address the aforementioned issues, existing plastic parts are typically molded as a single piece, requiring replacement of the entire unit when damaged, which increases replacement costs. Furthermore, they lack good impact resistance, transmitting significant force to the vehicle body upon impact, and lack auxiliary positioning functions, making installation cumbersome.

[0004] To address these issues, the present invention provides a lightweight, impact-resistant automotive injection molded part. Summary of the Invention

[0035] The present application will be further described in detail below with reference to the accompanying drawings and embodiments.

[0036] Reference Figures 1 to 5 This application provides a lightweight, impact-resistant automotive injection molded part, including a plastic part 1 and a plastic part 2. The plastic part 2 is disposed on one side of the plastic part 1. Mounting assemblies 3 are fixedly mounted on one side of both the plastic part 1 and the plastic part 2. The mounting assembly 3 includes a connecting frame 31 and a fixing frame 32. The connecting frame 31 is fixedly mounted on one side of the plastic part 1, and the fixing frame 32 is fixedly mounted on one side of the plastic part 2. A threaded rod 33 is threadedly connected to one side of the fixing frame 32. One end of the threaded rod 33... A movable plate 34 is connected via a bearing. A U-shaped frame 35 is fixedly installed on one side of the movable plate 34. A connecting rod 36 is hinged to the inner wall of the U-shaped frame 35. A sliding groove 37 is provided on one side of the fixed frame 32. A clamping plate 38 is slidably connected to one side of the sliding groove 37.

The connecting rod 36 is hinged to the second U-shaped frame 39. A knob is fixedly connected to one end of the threaded rod 33. The knob is welded to the threaded rod 33.

[0037] In this embodiment, plastic part 1 and plastic part 2 are first aligned. Then, rotating the threaded rod 33 can drive the moving plate 34 to move, so that the moving plate 34 can drive the connecting rod 36 to move. This allows the connecting rod 36 to slide inside the slide groove 37 through the clamping plate 38, so that the clamping plate 38 can be engaged with the connecting frame 31 to complete the installation of plastic part 1 and plastic part 2. The installation is simple and reliable.

[0038] Reference Figures 1 to 5In one aspect of this embodiment, a connecting plate 4 is provided on one side of the plastic part 1, and a protective component 5 is provided on one side of the connecting plate 4. The protective component 5 includes a T-shaped block 51 and a T-shaped block 52. The T-shaped block 51 and the T-shaped block 52 are respectively snapped onto one side of the connecting plate 4. A tripod 53 is fixedly installed on one side of both the T-shaped block 51 and the T-shaped block 52. A connecting ring 54 is fixedly installed on one side of the tripod 53.

Rotating the rotating block 59 can drive the threaded rod 2 57 to rotate inside the cylinder 56, so that the locking block 58 can be snapped together with the connecting ring 54 to fix the tripod 53. When the plastic parts 1 and 2 are impacted, the tripod 53 can also play a good buffering role to reduce the force of the impact.

[0040] Reference Figures 1 to 5 In one aspect of this embodiment, a positioning component 6 is fixedly installed on one side of both the plastic part 1 and the connecting plate 4. The positioning component 6 includes a positioning plate 61 and a positioning plate 62.

Then the bolts are used to easily install the plastic part 1 and the connecting plate 4, and the installation is simple and reliable.

[0042] Working principle: First, align plastic part 1 and plastic part 2. Then, rotate the threaded rod 33 to drive the moving plate 34 to move, which in turn drives the connecting rod 36 to move. This allows the connecting rod 36 to slide through the locking plate 38 inside the slide groove 37, so that the locking plate 38 can be engaged with the connecting frame 31 to complete the installation of plastic part 1 and plastic part 2. The installation is simple and reliable.

[0043] Then, T-block 1 51 and T-block 2 52 are snapped together with connecting plate 4. Rotating rotating block 59 can drive threaded rod 2 57 to rotate inside cylinder 56, so that locking block 58 can be snapped together with connecting ring 54 to fix tripod 53. When plastic parts 1 and 2 are impacted, tripod 53 can also play a good buffering role to reduce the force of impact.

[0044] Finally, the clip 63 is inserted into the slot 64, and the second positioning plate 62 is inserted into the first positioning plate 61. Then the magnet 65 is attracted to the first positioning plate 61. Then, the bolts are used to easily install the plastic part 1 and the connecting plate 4. The installation is simple and reliable.
