Description

Technical Field

[0001] The present application relates to the technical field of seat cushion suspension spring structures, and in particular to a car seat cushion suspension spring structure. Background Art

[0002] The suspension spring structure of a car seat cushion is often called a spring support system and is used to provide comfort and support. When you sit in the seat, the springs compress and absorb your weight, providing support, while the cushioning material provides additional comfort and shock absorption, absorbing vibrations and impacts.

[0003] Suspension spring structures typically consist of coil springs or leaf springs, either in combination with a damper. Coil springs are the most common type and consist of metal coils that compress and return to shape, providing support and cushioning, while leaf springs consist of curved metal sheets and are commonly used in truck and commercial vehicle seats to provide more rigid support.

[0004] However, during the use of the suspension spring structure, the hardness of the spring is uniform. This results in that for lighter people, the vibration feeling is not obvious when riding, and the comfort is slightly poor. For heavier people, the support is slightly poor when riding, and they easily get tired after riding for a long time, thus affecting the best riding experience and making it difficult to meet the riding needs of different people. Therefore, it is necessary to provide a car seat suspension spring structure to solve the above problems.

[0005] It should be noted that the above information disclosed in this Background section is only for understanding the background technology of the present application concept, and therefore, it may contain information that does not constitute prior art. Summary of the Invention

[0006] Based on the above problems existing in the prior art, the problem to be solved by this application is: to provide a car seat cushion suspension spring structure that ensures the best riding experience for people of different body shapes and meets the riding needs of different people.

[0007] The technical solution adopted by the present application to solve the technical problem is: a car seat cushion suspension spring structure, comprising:

[0008] seat frame;

[0009] a bottom plate disposed below the seat frame;

[0010] A suspension spring mechanism is installed between the seat frame and the bottom plate, and has:

[0011] A crossbeam frame, the crossbeam frame is mounted on the bottom of the seat frame, and a concave frame is mounted on the lower end of the crossbeam frame;

[0012] A base frame is provided below the concave frame and is mounted on the upper end of the bottom plate;

[0013] A screw, which is rotatably connected to the center of the upper end of the base frame, passes through the bottom of the concave frame, is threadedly connected to a nut, a platform is provided at the bottom of the concave frame, and the nut is located above the platform. A spring is installed between the concave frame and the base frame, and the spring is sleeved on the outside of the screw;

[0014] A driving member is installed on the outside of the nut and is used to adjust the nut.

[0015] Furthermore, the driving member has a turbine fixedly mounted on the outside of the nut, the outside of the concave frame is rotatably connected to a driving rod, a worm is fixedly mounted on the driving rod, the worm and the turbine are transmission-connected, a driving motor is fixedly mounted on the outside of the concave frame, and the output shaft of the driving motor is fixedly connected to the driving rod.

[0016] Furthermore, movable sleeves are fixedly installed on both sides of the lower end of the concave frame, and sliding rods are fixedly installed on both sides of the upper end of the base frame, and the sliding rods are slidably connected to the inside of the movable sleeves.

[0017] Furthermore, a compression spring is fixedly installed between the movable sleeve and the base frame, and the compression spring is sleeved on the outer side of the sliding rod.

[0018] Furthermore, a slide bar is provided below the seat frame, the bottom plate is fixedly installed between the slide bars, connecting plates are fixedly installed on both sides of the lower end of the seat frame, the connecting plates are hinged to the upper end of the slide bar, and the slide bar is suitable for being installed in a slide groove on a car.

[0019] Furthermore, a control switch is provided on one side of the seat frame, and the control switch is electrically connected to the drive motor.

[0020] The beneficial effect of the present application is that the present application provides a car seat suspension spring structure, which is provided with a suspension spring mechanism. When a heavier person sits on the seat, the drive motor is started to rotate forward, so that the worm drives the turbine to rotate in the opposite direction, thereby causing the nut to move downward on the screw rod, thereby reducing the telescopic length of the spring, reducing the elastic potential energy of the spring, and at the same time, the elastic potential energy of the compression spring is also reduced, thereby ensuring the support of the suspension spring mechanism, thereby ensuring the best riding experience for people of different body shapes and meeting the riding needs of different people.

[0030] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0031] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0032] like Figure 1As shown, the present application provides a car seat cushion suspension spring structure, including a seat frame 1, which is used to provide support for the overall structure. A slide bar 12 is also provided under the seat frame 1, and a base plate 13 is fixedly installed between the slide bars 12, and connecting plates 11 are fixedly installed on both sides of the lower end of the seat frame 1. In the present application, the connecting plate 11 is hinged to the upper end of the slide bar 12, and the slide bar 12 is suitable for being installed in a slide groove on the car, so that the slide bar 12 can slide in the slide groove to adjust the position of the seat frame 1.

[0033] At the same time, multiple groups of suspension spring mechanisms 2 are fixedly installed between the seat frame 1 and the bottom plate 13 , and the suspension spring mechanisms 2 are used to buffer and unload the seat frame 1 .

[0034] like Figure 2-Figure 3 As shown, the suspension spring mechanism 2 has a crossbeam frame 21, which is fixedly mounted on the bottom of the seat frame 1, and a concave frame 22 is fixedly mounted on the lower end of the crossbeam frame 21, and movable sleeves 23 are fixedly mounted on both sides of the lower end of the concave frame 22;

[0035] At the same time, a base frame 24 is provided below the concave frame 22, and the base frame 24 is fixedly mounted on the upper end of the bottom plate 13. Slide rods 241 are fixedly mounted on both sides of the upper end of the base frame 24. The slide rods 241 are slidably connected to the inside of the movable sleeve 23, and a compression spring 242 is fixedly mounted between the movable sleeve 23 and the base frame 24. The compression spring 242 is sleeved on the outer side of the slide rod 241. Therefore, when the seat frame 1 is subjected to force, the crossbeam frame 21 will be pressed downward, and the movable sleeve 23 will be moved downward through the concave frame 22, and the compression spring 242 will be squeezed, so that the seat frame 1 is auxiliary buffered by the compression spring 242.

[0036] The nut 26 is threadedly connected to the screw rod 25 at the upper end center of the base frame 24, and the screw rod 25 passes through the bottom of the concave frame 22. The screw rod 25 is threadedly connected to the nut 26. At the same time, a spring 27 is fixedly installed between the concave frame 22 and the base frame 24. The spring 27 is sleeved on the outside of the screw rod 25. It should be noted that a platform is provided at the bottom of the concave frame 22, and the nut 26 is located above the platform. The position of the platform can be changed by the action of the spring 27 and the nut 26. Specifically, by rotating the nut 26, the nut 26 can be made to move linearly on the screw rod 25. When the nut 26 is downward, it will be pressed on the platform and drive the concave frame 22 to move downward synchronously. When the nut 26 is upward, it will separate from the platform. At this time, the concave frame 22 will move upward with the reset elastic force of the spring 27. Therefore, by adjusting the telescopic length of the spring 27, its hardness is changed, thereby changing the elastic potential energy of the spring 27.

[0037] In order to more conveniently adjust the nut 26, a driving member 28 is installed on the outside of the nut 26. The driving member 28 has a turbine 281 fixedly mounted on the outside of the nut 26. At the same time, the outside of the concave frame 22 is rotatably connected to a driving rod 282. A worm 283 is fixedly mounted on the driving rod 282. The worm 283 is transmission-connected to the turbine 281.

[0038] In addition, a drive motor 284 is fixedly installed on the outer side of the concave frame 22, and the output shaft of the drive motor 284 is fixedly connected to the drive rod 282. Therefore, starting the drive motor 284 can drive the drive rod 282 and the worm 283 to rotate at the same time, and the turbine 281 rotates accordingly, and drives the nut 26 to rotate, thereby adjusting the position of the nut 26 on the screw 25.

[0039] In the present application, a control switch (not shown) is provided on one side of the seat frame 1 , and the control switch is electrically connected to the drive motor 284 , thereby facilitating the user to adjust the suspension spring mechanism 2 .

[0040] To summarize: if a lighter person is to ride, the drive motor 284 is started to rotate in reverse, causing the worm 283 to drive the turbine 281 to rotate, thereby causing the nut 26 to move upward on the screw 25, thereby increasing the extension length of the spring 27, increasing the elastic potential energy of the spring 27, and at the same time increasing the elastic potential energy of the compression spring 242, thereby making the vibration feeling stronger during riding and improving the comfort;

[0041] When a heavier person rides, the drive motor 284 is started to rotate forward, causing the worm 283 to drive the turbine 281 to rotate in the opposite direction, thereby causing the nut 26 to move downward on the screw 25, thereby reducing the telescopic length of the spring 27, reducing the elastic potential energy of the spring 27, and at the same time, the elastic potential energy of the compression spring 242 is also reduced, ensuring the support of the suspension spring mechanism 2, thereby ensuring the best riding experience for people of different body shapes and meeting the riding needs of different people.

[0042] The above description is merely a preferred embodiment of the present application and is not intended to limit the present application. Various modifications and variations are possible for those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present application shall be included within the scope of protection of the present application.
