[0002] Automotive interior injection molding refers to various plastic parts used in the interior of the car, which are usually made by injection molding. Injection molding is a process in which thermoplastic or thermosetting materials are injected into a closed mold and solidified under certain conditions. This technology is widely used in the automotive industry because it can produce parts with complex shapes, precise dimensions and smooth surfaces.

[0003] Existing interior injection molded parts themselves also have a certain rigidity, and their deformation capacity is limited when impacted, resulting in poor energy absorption effect, which often causes the impact energy to not be completely absorbed, and then causes the impact energy to be transferred to other parts of the vehicle, causing damage to the vehicle's interior parts, thereby reducing the safety of the vehicle and increasing the repair cost after the vehicle collision. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model provides a buffer structure automobile interior injection molded part to solve the problem that impact energy is transferred to other parts of the vehicle, thereby causing damage to the vehicle's interior parts, which in turn leads to reduced vehicle safety and increased maintenance costs after a vehicle collision.

[0005] To achieve the above objectives, the utility model is implemented through the following technical solutions: a buffer structure automobile interior injection molding comprises a thick sheet interior part, a corresponding part is provided on one side of the upper surface of the thick sheet interior part, a corresponding groove is provided on the bottom of the thick sheet interior part, a raised part is provided on one side of the thick sheet interior part close to the corresponding part, a through hole is opened on the upper surface of the raised part, a connecting hole is provided on one side of the raised part, a support is fixedly installed on the inner arc surface of the raised part, a raised end is provided on the top of the upper surface of the support part, the raised end is matched with the lower surface of the raised part, and the surface of the raised end of the support part A through groove is opened, and an elastic member is movably overlapped on the lower surface of the support member, and a spiral recess is provided on the outer arc surface of the elastic member, and a spring is provided on the inner arc surface of the spiral recess. Through the provided support member, the stability of the elastic member is maintained under normal circumstances, thereby preventing the thick-sheet interior decoration member from shaking during driving, thereby increasing the stability of the interior decoration member, and thereby increasing the stability of the vehicle structure. The spiral recess on the support member fills the pitch on the elastic member, thereby limiting the deformation of the elastic member, thereby maintaining the shape of the elastic member unchanged during normal driving of the vehicle, thereby making the connection of the interior decoration more stable.

[0006] Optionally, a buffer member is connected through the lower surface of the elastic member, a through groove is provided on the upper surface of the buffer member, the support member and the buffer member are both hollow structures, and buffer portions are provided on the top and bottom of the elastic member.

[0007] Optionally, a connecting block is fixedly mounted on the lower surface of the buffer component, the connecting block is parallel to the thick-sheet interior decoration component, and a fixing component is fixedly mounted on the middle part of the inner bottom wall of the buffer component.

[0012] The utility model provides a buffer structure automobile interior injection molded part, which has the following beneficial effects:

[0013] 1. By setting the support parts, the elastic parts are kept stable under normal circumstances, thereby preventing the thick interior parts from shaking during driving, thereby increasing the stability of the interior parts and the stability of the vehicle structure. The spiral recesses on the support parts fill the pitch on the elastic parts, thereby limiting the deformation of the elastic parts, thereby keeping the shape of the elastic parts unchanged during normal driving of the vehicle, thereby making the connection of the interior more stable.

[0014] 2. The energy of the impact is absorbed by the deformation of the spring on the elastic part.

[0022] See also Figures 1 to 4The utility model provides a technical solution: a buffer structure automobile interior injection molding part, including a thick sheet interior part 1, a corresponding part 101 is provided on one side of the upper surface of the thick sheet interior part 1, and the corresponding part 101 is provided with a corresponding groove at the bottom of the thick sheet interior part 1, and an arched part 102 is provided on the side of the thick sheet interior part 1 close to the corresponding part 101, and a through hole 103 is provided on the upper surface of the arched part 102, and a connecting hole 104 is provided on one side of the arched part 102, and a support member 2 is fixedly installed on the inner arc surface of the arched part 102, and a raised end is provided on the top of the upper surface of the support member 2, and the raised end is matched with the lower surface of the arched part 102, and a through groove is provided on the surface of the raised end of the support member 2, and an elastic member 3 is movably overlapped on the lower surface of the support member 2, and a spiral recess 301 is provided on the outer arc surface of the elastic member 3, and a spring 4 is provided on the inner arc surface of the spiral recess 301.

[0023] By setting the support member 2, the elastic member 3 is kept stable under normal circumstances, thereby preventing the thick interior trim 1 from shaking during driving, thereby increasing the stability of the interior trim and the stability of the vehicle structure. The spiral recess 301 on the support member 2 fills the pitch on the elastic member 3, thereby limiting the deformation of the elastic member 3, thereby maintaining the shape of the elastic member 3 unchanged during normal driving of the vehicle, thereby making the connection of the interior trim more stable.

[0024] A buffer member 5 is connected through the lower surface of the elastic member 3, and a through groove is provided on the upper surface of the buffer member 5. Both the support member 2 and the buffer member 5 are hollow structures. Buffer parts are provided on the top and bottom of the elastic member 3. A connecting block 501 is fixedly installed on the lower surface of the buffer member 5, and the connecting block 501 is parallel to the thick-sheet interior decoration member 1. A fixing member 6 is fixedly installed in the middle of the inner bottom wall of the buffer member 5, and a locking member 7 is connected through the inner arc surface of the fixing member 6. An extension end 701 is provided at the bottom of the locking member 7, and one end of the extension end 701 is connected to the outside of the fixing member 6. A hook end 702 is provided at the end of the locking member 7 away from the fixing member 6, and the hook end 702 penetrates to the outside of the arched portion 102. One end of the hook end 702 penetrates the arched portion 102 and is connected and adapted to the connecting hole 104. The spring 4 is conical in shape, and the elastic member 3 is a spiral structure. The elastic member 3 is vertically connected to the thick-sheet interior decoration member 1.

[0025] The energy of the impact is absorbed by the deformation of the spring 4 on the elastic member 3. Due to the elastic characteristics of the elastic member 3 itself, the shape of the elastic member 3 can be easily changed in the entire anti-collision beam structure, so that the impact energy can be absorbed by the elastic member 3 first, thereby preventing the energy from being transferred to other components, thereby preventing damage to other components, thereby increasing driving safety and reducing post-collision repair costs.

[0026] In the utility model, the working steps of the device are as follows:

[0027] When the thick sheet interior decoration part 1 is hit, the impact force is transmitted to the buffer part 5 at the bottom, and then to the elastic part 3, so that the elastic part 3 is compressed, and then the energy of the impact is absorbed by the deformation of the spring 4 on the elastic part 3. Due to the elastic characteristics of the elastic part 3 itself, it is easy to change its shape in the entire anti-collision beam structure, so that the impact energy can be absorbed by the elastic part 3 first, thereby preventing the energy from being transmitted to other components, thereby preventing damage to other components, thereby increasing driving safety and reducing maintenance costs after a collision; at the same time, through the setting of the support part 2, the elastic part 3 is kept stable under normal circumstances, thereby preventing the thick sheet interior decoration part 1 from shaking during driving, thereby increasing the stability of the interior decoration part, and thereby increasing the stability of the vehicle structure. The spiral recess 301 on the support part 2 fills the pitch on the elastic part 3, thereby limiting the deformation of the elastic part 3, and thereby keeping the shape of the elastic part 3 unchanged during normal driving of the vehicle, thereby making the connection of the interior more stable, thereby avoiding uncertainty in the position of the interior decoration when the vehicle is hit.
