Description

Technical Field

[0001] This utility model relates to the field of automotive interior injection molding technology, specifically a cushioning structure automotive interior injection molding part. Background Technology

[0002] Automotive interior injection molded parts refer to various plastic components used inside automobiles, which are typically manufactured using the injection molding process. Injection molding is a process in which thermoplastic or thermosetting materials are injected into a closed mold and allowed to solidify under specific conditions. This technology is widely used in the automotive industry because it can produce parts with complex shapes, precise dimensions, and smooth surfaces.

[0003] The prior art document, "A Buffer Structure Injection Molded Part for Automotive Interior Trim," (CN222793424U), describes a system where a support member is used to maintain the stability of the elastic component under normal conditions. This prevents the thick interior trim piece from swaying during driving, thereby increasing the stability of the interior trim piece and the vehicle structure. The spiral recess on the support member fills the pitch of the elastic component, limiting its deformation and ensuring that the shape of the elastic component remains unchanged during normal vehicle operation, thus making the connection of the interior trim piece more stable.

[0004] However, the injection-molded interior parts for automobiles have weak cushioning structures and poor cushioning performance, making it difficult to effectively protect the occupants of the vehicle in the event of a strong impact, causing inconvenience to users and failing to meet their needs.

[0007] Furthermore, the top and bottom of the damping column are fixedly connected to the inner wall of the door injection molded part.

[0008] Furthermore, the number of transverse adhesive strips is several, and each pair of transverse adhesive strips is designed to be equidistant from each other.

[0009] Furthermore, a speaker hole is provided on one side of the front surface of the injection-molded door part.

[0010] Furthermore, the two sides of the energy-absorbing rubber ball are fixedly connected to the buffer and the shock-absorbing pad, respectively.

[0020] The utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. The following embodiments are only descriptive and are not limiting of the scope of protection of this utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a buffer structure automotive interior injection molded part, including a door injection molded part 1, which serves to seal the door. The door injection molded part 1 has an internal cavity, and a damping column 2 is disposed inside the door injection molded part 1. The damping column 2 absorbs vibrations. A transverse rubber strip 3 is fixedly disposed on the rear surface of the damping column 2, providing lateral reinforcement. A buffer 4 is fixedly disposed on the rear surface of the transverse rubber strip 3, and is used to house corresponding components. The buffer 4 has an internal cavity. Guide rods 5 are fixedly installed at the top and bottom of the buffer 4 cavity. The guide rods 5 are used to cooperate with the connecting rods 8. A shock-absorbing pad 6 is installed at the front end of the buffer 4. The shock-absorbing pad 6 can absorb shock. Two energy-absorbing rubber balls 7 are installed between the shock-absorbing pad 6 and the buffer 4. The energy-absorbing rubber balls 7 can absorb energy. A connecting rod 8 is fixedly installed at the top and bottom of one side of the shock-absorbing pad 6. The connecting rod 8 is used to connect with the guide rods 5. An energy-absorbing spring 9 is fixedly installed at the middle of one side of the shock-absorbing pad 6. The energy-absorbing spring 9 can absorb impact force.

[0022] Furthermore, the top and bottom of the damping column 2 are fixedly connected to the inner wall of the door injection molded part 1, wherein the damping column 2 can absorb vibration.

[0023] Furthermore, the number of transverse adhesive strips 3 is several, and the distance between each pair of transverse adhesive strips 3 is equidistant. The transverse adhesive strips 3 serve to provide transverse reinforcement.

[0024] Furthermore, a speaker hole 10 is provided on one side of the front surface of the door injection molded part 1, wherein the speaker hole 10 facilitates the propagation of sound.

[0025] Furthermore, the energy-absorbing rubber ball 7 is fixedly connected to the buffer 4 and the shock-absorbing pad 6 on both sides, and the energy-absorbing rubber ball 7 is capable of absorbing energy.

[0026] Furthermore, one end of the connecting rod 8 extends into the interior of the buffer 4, and one end of the guide rod 5 passes through the connecting rod 8 and extends to its exterior. The guide rod 5 and the connecting rod 8 are movably connected. This design allows the shock-absorbing pad 6 to move.

[0027] Furthermore, one end of the energy-absorbing spring 9 passes through the buffer 4 and is fixedly connected to the inner wall of the buffer 4, wherein the energy-absorbing spring 9 is capable of absorbing impact force.

[0028] Working principle: When this device is subjected to an external impact, the impact force will first act on the shock-absorbing pad 6 through the car door. The shock-absorbing pad 6 and the energy-absorbing rubber ball 7 will act synchronously under the action of the impact force to absorb the vibration. After being subjected to the impact force, the shock-absorbing pad 6 will drive the connecting rod 8 to move, which will compress the energy-absorbing spring 9, so that the energy-absorbing spring 9 will be compressed and buffered, and the impact force will be buffered and absorbed again. Then, the remaining impact force will act on the reinforcement composed of the transverse rubber strip 3 and the damping column 2. Through this design, the impact performance is increased, and the remaining impact force is absorbed again.

[0029] Based on the above work process, we can conclude that:

[0030] This cushioning structure, an injection-molded part for automotive interiors, incorporates damping pillars 2, transverse rubber strips 3, shock-absorbing pads 6, energy-absorbing rubber balls 7, and energy-absorbing springs 9. This multi-stage cushioning mechanism significantly reduces the impact force during a collision, minimizing harm to occupants and providing convenience. It enhances the device's practicality and meets user needs.
