Description

Technical Field

[0001] The utility model relates to the technical field of automobile seat cushions, and particularly relates to an elastic structure of an automobile seat cushion. Background Technique

[0002] An automobile seat cushion is one of the basic accessories in an automobile. Since a driver needs to sit on the seat cushion all the time when driving, the seat cushion is required to have good support effect and elasticity. In order to increase the comfort of the seat cushion and the safety requirements of the automobile itself, accessories such as sensors and ventilation devices also need to be installed in the seat cushion. The interior of the existing seat cushion includes a support frame body, and an elastic member is arranged in the support frame body. Although the comfort of the seat cushion is ensured, other accessories cannot be installed conveniently.

[0003] The patent with the application number 202420004202.2 discloses an elastic structure of an automobile seat cushion, which includes a steel wire skeleton and an accessory rack. The steel wire skeleton includes first steel wires, second steel wires, third steel wires and fourth steel wires that are arranged side by side at intervals. A first hook is constructed at the first end of the steel wire skeleton, and a second hook is constructed at the second end of the steel wire skeleton. A first connecting beam is arranged at a position on the steel wire skeleton close to the first end, and a second connecting beam is arranged at a position on the steel wire skeleton close to the second end. Both the first connecting beam and the second connecting beam are fixed on four steel wires at the same time; the accessory rack is arranged between the second steel wire and the third steel wire.

[0004] The above technical solution uses multiple embedded steel wires to install accessories. Since the steel wires are respectively fixed between the first connecting beam and the second connecting beam, the strength of the steel wires themselves is limited, and the parts will slide on the surface of the steel wires after installation, and the stability is poor compared with directly installing the accessories on the connecting beam. Therefore, the present application provides an elastic structure of an automobile seat cushion to meet the requirements. Content of the Utility Model

[0005] The technical problem to be solved by the utility model is to provide an elastic structure of an automobile seat cushion to solve the problems that in the existing structure, since the steel wires are respectively fixed between the first connecting beam and the second connecting beam, the strength of the steel wires themselves is limited, and the parts will slide on the surface of the steel wires after installation, and the stability is poor compared with directly installing the accessories on the connecting beam.

[0006] To solve the above technical problems, the utility model provides the following technical solutions:

[0018] In the above solution, an elastic plate in a frame structure is provided at the top end of the base. A plurality of accessory mounting brackets are fixed in the elastic plate, and load-bearing rods fixed to the accessory mounting brackets are provided in the elastic plate. After both ends of the accessory mounting bracket are inserted into the convex portions, the bolts are tightened to keep them fixed. After the accessory mounting bracket is fixed, the accessories of the seat are installed and fixed through the accessory fixing holes. The accessory mounting bracket prevents the accessories from shaking after installation, improving the stability of the accessory installation.

[0019] A fixing tube is embedded at the top end of the base. The fixing tube and the telescopic rod are fixed to the base and the elastic plate respectively through fastening parts. When the elastic plate is subjected to gravity, it squeezes the spring through the anti-detachment part to undergo elastic deformation for buffering, and during the elastic deformation process, the air in the fixing tube is compressed. The compressed air buffers the squeezing force, thus avoiding the situation that the spring is squeezed and deformed due to excessive squeezing force. At the same time, after unscrewing the sealing knob, air can be injected into or extracted from the sealing tube through the air pipe to adjust the air pressure, and then the pressure buffering performance of the gas can be adjusted.

[0033] As Figure 1 and Figure 3As shown, an embodiment of the present utility model provides an elastic structure for an automotive seat cushion, which includes a base 1 and an elastic plate 5 disposed above the base 1. A plurality of accessory mounting brackets 7 are horizontally and fixedly embedded in the elastic plate 5, and a load-bearing rod 4 fixedly inserted into the accessory mounting brackets 7 is longitudinally installed on the inner wall of the elastic plate 5. A plurality of fixed tubes 17 are fixedly embedded in an array on the top end of the base 1 in a rectangular pattern. A telescopic rod 20 fixed to the elastic plate 5 is hermetically inserted into the fixed tubes 17, and a spring 18 is embedded in the fixed tubes 17. A connecting tube 8 is installed at the bottom end of the fixed tube.

[0034] A plurality of part slots 6 are formed on the top end of the base 1. Mounting holes 2 and waist slots 3 are respectively formed on the inner walls of the part slots 6. Support frames 10 are symmetrically and fixedly installed on both sides of the bottom end face of the base 1. Sliders 11 are installed at the bottom ends of the plurality of support frames 10. Protrusion parts 15 are equidistantly and fixedly installed on both sides of the inner wall of the elastic plate 5. Both ends of the accessory mounting bracket 7 are snugly inserted into the protrusion parts 15. A plurality of accessory fixing holes 13 are formed on the accessory mounting bracket 7. Bolts 14 are threadedly inserted into the accessory mounting bracket 7 at the top ends of the protrusion parts 15. After both ends of the accessory mounting bracket 7 are inserted into the protrusion parts 15, the bolts 14 are tightened to keep them fixed. After the accessory mounting bracket 7 is fixed, accessories of the seat are installed and fixed through the accessory fixing holes 13.

[0035] As Figure 2 and Figure 4 As shown, an air tube 12 is fixed between two adjacent connecting tubes 8. A sealing knob 9 is threadedly inserted into the air tube 12. A spring 18 is embedded and installed in the fixed tube 17. The top end of the connecting tube 8 is communicated with the fixed tube 17. An anti-disengagement part 16 is fixed to the bottom end of the telescopic rod 20. The anti-disengagement part 16 abuts against the inner wall of the fixed tube 17. A sealing ring 19 is fixedly embedded on the outer wall of the anti-disengagement part 16. The sealing ring 19 is tightly connected with the inner wall of the fixed tube 17. Fastening parts 21 are fixedly installed on the outer walls of the top ends of the fixed tube 17 and the telescopic rod 20 respectively. The two fastening parts 21 are respectively embedded and installed in the base 1 and the elastic plate 5. When the elastic plate 5 is subjected to gravity, it elastically deforms by squeezing the spring 18 through the anti-disengagement part 16, and compresses the air in the fixed tube 17 during the elastic deformation process. The compressed air buffers the extrusion force, thereby avoiding the situation that the spring 18 is squeezed and deformed due to excessive extrusion force.

[0036] The working principle of the technical solution provided by the present utility model is as follows:

[0037] During use, insert both ends of the fitting mounting bracket 7 into the protruding portions 15 and then tighten the bolts 14 to keep it fixed. After being fixed, the fitting mounting bracket 7 installs and fixes the fittings of the seat through the fitting fixing holes 13. The fitting mounting bracket 7 prevents the fittings from shaking after installation. The fixed tube 17 and the telescopic rod 20 are respectively fixed to the base 1 and the elastic plate 5 through the fastening portion 21. When the elastic plate 5 is subjected to gravity, it squeezes the spring 18 through the anti-disengagement portion 16 to undergo elastic deformation for buffering, and during the elastic deformation process, the air in the fixed tube 17 is compressed. The compressed air buffers the extrusion force, thus avoiding the situation where the spring 18 is squeezed and deformed due to excessive extrusion force. At the same time, after unscrewing the sealing knob 9, injecting air into or extracting air from the sealing tube through the air pipe 12 can adjust the air pressure, and further adjust the pressure buffering performance of the gas. The present utility model covers any alternatives, modifications, equivalent methods, and solutions made within the essence and scope of the present utility model. In order to enable the public to have a thorough understanding of the present utility model, specific details are described in detail in the following preferred embodiments of the present utility model. However, those skilled in the art can fully understand the present utility model without these detailed descriptions.
