[0014] Beneficial effects
[0015] This invention provides a highly comfortable seat support structure. Compared with the prior art, it has the following advantages:
[0016] 1. This high-comfort seat support structure has an adjustable component inside the device. The lever drives the telescopic rod to slide along the base and extension cylinder via a screw. The moving telescopic rod drives the array of extension arms and moving wheels to rotate through the base plate and array of traction frames, which helps to extend or retract the extension arms and moving wheels. This allows the user to adjust the bottom of the seat support according to their needs, saving space and eliminating the need for the user to frequently disassemble the support.
[0017] 2. This high-comfort seat support structure incorporates springs within the device. When a user sits on the seat, the seat causes the mounting plate and slider to move downwards. The slider compresses the spring, and the spring generates elastic force to cushion the slider and mounting plate, reducing the impact of the user's downward force on the overall support structure and improving user comfort.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0024] See Figures 1-4 This utility model provides the following two technical solutions:
[0025] First embodiment: A high-comfort seat support structure includes a base 1, and a support member for providing support for the seat is installed on the upper side of the base 1. The support member includes: an array of extendable arms 2, which are rotatably connected to the bottom edge of the base 1 for storage of the support end; an array of moving wheels 3, which are installed on the lower side of the extendable arms 2 for overall movement of the device; and an array of stops 4, which are installed on the top of the base 1 and used to limit the top of the extendable arms 2.
[0026] Adjustment component 5, installed on base 1 for storing and adjusting array of extendable arms 2, includes an extendable cylinder 51 installed in the middle of the upper side of base 1, a slider 52 slidably connected to the upper side of extendable cylinder 51, a spring 54 for providing cushioning to slider 52 installed inside extendable cylinder 51, a mounting plate 53 for mounting seat installed on top of slider 52, and several mounting screw holes on the edge of mounting plate 53. Adjustment component 5 also includes a bracket assembly 56 for pulling extendable arms 2 to rotate, bracket assembly 56 includes a telescopic rod 561 slidably connected to base 1 and the inner side of extendable cylinder 51, a base plate 562 installed at the bottom of telescopic rod 561, an array of traction frames 563 for adjusting the angle of extendable arms 2 rotatably connected to the edge of base plate 562, and a height adjustment component 55 for adjusting the height of telescopic rod 561 installed on extendable cylinder 51;
[0027] The movable wheel 3 is rotatably connected to the lower side of the extension arm 2. The lower side of the stop block 4 is provided with a limiting groove that fits with the extension arm 2. The extension arm 2 is inclinedly set on the lower edge of the base 1. The height adjustment component 55 includes a screw 553 rotatably connected to the inside of the extension cylinder 51 and threadedly connected to the middle of the telescopic rod 561. The extension cylinder 51 is shown to be equipped with a bevel gear assembly 551 for driving the screw 553. The left side of the extension cylinder 51 is rotatably connected to a lever 552 for driving the bevel gear assembly 551. The driving bevel gear in the bevel gear assembly 551 is coaxially fixedly connected to the lever 552. The driven bevel gear in the bevel gear assembly 551 is coaxially fixedly connected to the screw 553. The extension cylinder 51 is provided with a second movable groove on the side near the bevel gear assembly 551.
[0028] The base plate 562 is located on the lower side of the base 1. The traction frame 563 is tilted and rotatably connected to the edge of the base plate 562. The top of the telescopic rod 561 is provided with a second limiting block that is slidably connected to the inner side of the extension cylinder 51. The lever 552 drives the telescopic rod 561 to slide along the base 1 and the extension cylinder 51 through the screw 553. The moving telescopic rod 561 drives the array of extension arms 2 and the moving wheels 3 to rotate through the base plate 562 and the array of traction frames 563 respectively. After the extension arm 2 is extended to contact the stop block 4, the lever 552 stops rotating, realizing the extension arm 2 and the moving wheels 3.
[0029] The main difference between the second implementation method and the first implementation method is that:
[0030] The bottom of the slider 52 is equipped with a first limiting block that is slidably connected to the extension cylinder 51. The top of the spring 54 is fixedly connected to the first limiting block. The extension cylinder 51 is provided with a first movable groove near the first limiting block and on the side of the spring 54. When the user sits on the seat, the seat drives the mounting plate 53 and the slider 52 to move downward. The slider 52 compresses the spring 54, and the spring 54 generates elastic force to provide cushioning for the slider 52 and the mounting plate 53, thereby improving the user's comfort.
[0031] Furthermore, all content not described in detail in this specification is existing technology known to those skilled in the art, and the model parameters of each electrical appliance are not specifically limited; conventional equipment can be used.
[0032] In use, the user removes the entire support structure and rotates the lever 552. The lever 552 drives the telescopic rod 561 to slide along the base 1 and the extension cylinder 51 via the screw 553. The moving telescopic rod 561 drives the array of extension arms 2 and the moving wheels 3 to rotate via the base plate 562 and the array of traction frames 563, respectively. After the extension arm 2 is extended to contact the stop block 4, the lever 552 is stopped. The corresponding seat is installed on the mounting plate 53 with screws. When the user sits on the seat, the seat drives the mounting plate 53 and the slider 52 to move downward. The slider 52 compresses the spring 54, and the spring 54 generates elastic force to provide cushioning for the slider 52 and the mounting plate 53. The moving wheels 3 facilitate the user to move the seat and the entire support structure.
