Technical Field

[0001] This utility model relates to the field of seat cushion frame technology, specifically to a seat cushion frame. Background Technology

[0002] Seat cushions are cushioning layers placed on the surface of seats. Their main functions are to improve riding comfort and protect the seat body and decorative space. The seat cushion frame is the core structural component that supports the seat cushion, and its design and materials directly affect riding comfort, safety and service life.

[0003] Currently, seat cushions are installed on special vehicles such as sightseeing buses and amusement park vehicles to improve passenger comfort. Existing seat cushion frames have a simple overall structure, supported by a frame and damped by multiple serpentine springs inside. The structure is relatively simple and the damping effect is poor. Therefore, a new seat cushion frame is proposed, which sets multiple first and second serpentine springs inside the seat cushion frame, and sets multiple compression springs between the first serpentine springs and the seat cushion frame, which can support and dampen the load-bearing parts. Utility Model Content

[0004] To address the problems in the prior art, this utility model provides a seat cushion frame, in which multiple first serpentine springs and second serpentine springs are arranged inside the cushion frame, and multiple compression springs are arranged between the first serpentine springs and the cushion frame, which can support and dampen the load-bearing parts.

[0005] The technical solution adopted by this utility model to solve its technical problem is a seat cushion frame, including a seat cushion frame, a first serpentine spring and a second serpentine spring. Bottom beams are welded to both ends of the bottom of the seat cushion frame, and cross beams are welded at equal intervals between the bottom beams.

[0006] The seat cushion frame is provided with first serpentine springs at equal intervals inside, and structural plates are welded at equal intervals inside the first serpentine springs. Compression springs are fixed at equal intervals between the structural plates and the crossbeam by bolts.

[0007] By adopting the above technical solutions, the bottom beam and crossbeam improve the structural stability of the seat cushion frame, and multiple compression springs support the first serpentine spring, thereby improving the vibration damping capability of the seat cushion frame.

[0008] Specifically, the second serpentine spring is fixed to the inside of the seat cushion frame, located outside the first serpentine spring, by bolts.

[0009] Specifically, connecting rods are welded at equal intervals on one side of the second serpentine spring, and the end of the connecting rod away from the second serpentine spring is fixed to the inside of the seat cushion frame by bolts.

[0010] Specifically, the seat cushion frame has a first reserved groove that is equidistantly opened on both sides, and a second reserved groove that is equidistantly opened on the other two sides.

[0011] Specifically, threaded grooves are equidistantly provided through the top of the bottom beam.

[0012] Specifically, the seat frame, bottom beam, and crossbeam are all made of stainless steel, and the first and second serpentine springs are both made of spring steel.

[0013] The beneficial effects of this utility model are:

[0014] (1) The seat cushion frame described in this utility model has multiple first serpentine springs and second serpentine springs that can disperse the pressure on the human body and prevent local collapse. Multiple compression springs can improve the support for areas prone to collapse. When the vehicle is bumpy, multiple first serpentine springs, second serpentine springs and compression springs absorb the impact and reduce the vibration amplitude transmitted to the human body. The overall vibration reduction effect is good.

[0015] (2) The seat cushion frame of this utility model has a bottom beam and a cross beam inside the seat cushion frame to support the seat cushion frame and improve the structural stability of the seat cushion frame. Attached Figure Description

[0022] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0023] Multiple first and second serpentine springs are installed inside the seat cushion frame, and multiple compression springs are installed between the first serpentine springs and the seat cushion frame to support and dampen the load-bearing parts. Figure 1-4As shown, the seat cushion frame of this utility model includes a seat cushion frame 1, a first serpentine spring 2 and a second serpentine spring 3. Bottom beams 101 are welded to both ends of the bottom of the seat cushion frame 1, and crossbeams 102 are welded at equal intervals between the bottom beams 101.

[0024] The seat frame 1 is provided with first serpentine springs 2 at equal intervals inside. Structural plates 201 are welded at equal intervals inside the first serpentine springs 2. Compression springs 202 are fixed at equal intervals between the structural plates 201 and the crossbeam 102 by bolts.

[0025] During use, the bottom beam 101 and the crossbeam 102 improve the structural stability of the seat frame 1, and multiple compression springs 202 support the first serpentine spring 2, thereby improving the vibration damping capability of the seat frame.

[0026] For example, such as Figure 4 As shown, the present invention also includes a second serpentine spring 3 fixed to the inside of the seat cushion frame 1 located outside the first serpentine spring 2 by bolts.

[0027] When in use, the second serpentine spring 3 is designed to distribute pressure on the human body.

[0028] For example, such as Figure 4 As shown, the present invention also includes a connecting rod 4 welded at equal intervals on one side of the second serpentine spring 3, and the end of the connecting rod 4 away from the second serpentine spring 3 is fixed to the inner side of the seat cushion frame 1 by bolts.

[0029] When in use, the connecting rod 4 is fixed inside the seat frame 1, which can improve the pressure bearing capacity of the second serpentine spring 3.

[0030] For example, such as Figure 2 As shown, the present invention also includes a first reserved groove 103 that is equidistantly opened on both sides of the seat cushion frame 1, and a second reserved groove 104 that is equidistantly opened on the other two sides of the seat cushion frame 1.

[0031] When in use, the opening of the first reserved slot 103 and the second reserved slot 104 can reduce the weight of the seat frame 1 and improve the ventilation capacity of the seat frame 1.

[0032] For example, such as Figure 2 As shown, the present invention also includes threaded grooves 105 that are equidistantly provided through the top of the bottom beam 101.

[0033] In use, the seat frame 1 can be fixed to the vehicle seat using bolts through the threaded groove 105.

[0034] For example, such as Figure 1As shown, the present invention also includes that the seat frame 1, the bottom beam 101 and the crossbeam 102 are all made of stainless steel, and the first serpentine spring 2 and the second serpentine spring 3 are both made of spring steel.

[0035] When in use, the seat frame 1, bottom beam 101 and crossbeam 102, made of stainless steel, are high in strength and not easily deformed, while the first serpentine spring 2 and the second serpentine spring 3, made of spring steel, are highly elastic.

[0036] In use, the seat frame 1 is provided with a bottom beam 101 and a cross beam 102 to support the seat frame 1, which can improve the structural stability of the seat frame 1. The seat frame 1 can be fixed to the seat of amusement park vehicles, sightseeing vehicles and other vehicles by using bolts through the threaded groove 105.

[0037] Multiple first serpentine springs 2 and second serpentine springs 3 are fixed inside the seat cushion frame 1, which can distribute the pressure of the human body, prevent local collapse, and not affect the air circulation at the bottom of the seat cushion, thus preventing stuffiness. Multiple compression springs 202 are set between the first serpentine springs 2 and the crossbeam 102 to improve the support for areas prone to collapse. When the vehicle is bumpy, the impact is absorbed by the multiple first serpentine springs 2, second serpentine springs 3 and compression springs 202, reducing the amplitude of vibration transmitted to the human body, resulting in good overall vibration reduction.
