AI Technical Summary

Technical Problem

Current electric car seats cannot adjust the height of the seat underneath, resulting in poor user comfort.

Method used

By designing a seat adjustment structure, including a base, slide rail, support, rotating connecting arm and cylinder, zero-gravity adjustment of the seat can be achieved, allowing the height of the front end of the seat to remain unchanged while the height of the rear end can be adjusted downwards. The use of a quadrilateral linkage structure and a double rotating arm design improves the reclining angle and comfort of the backrest.

Benefits of technology

The seat is designed to be more ergonomic when lying flat, improving user comfort, especially by allowing for a more natural bend in the legs and knees and reducing the angle between the backrest and the seat, thus providing a better reclining experience.

For ordinary skilled in the art, the specific meaning of the above terms in this application can be understood according to the specific circumstances.

[0025] Example 1

[0026] As Figures 1-4As shown, the application provides a seat adjusting structure, which comprises a base 1 and a slide rail 2, the base 1 is slidingly installed on the slide rail 2; a first support 3 and a second support 8, the second support 8 is fixed on the upper part of the first support 3; the second support 8 and the front end of the base 1 are rotationally connected, the first support 3 is rotationally connected with a first rotation connecting arm 6 on both sides of the rear end inside, the other side of the first rotation connecting arm 6 is rotationally connected with the rear end top of the base 1 through a second rotation shaft 7; a zero-gravity adjusting mechanism, which comprises a second connecting seat 11, a second fixed plate 14, a second rotation connecting arm 12 and a third rotation connecting arm 13, both ends of the second rotation connecting arm 12 are rotationally connected with the front end of the second connecting seat 11 and the upper end of the second fixed plate 14 respectively; both ends of the third rotation connecting arm 13 are rotationally connected with the rear end of the second connecting seat 11 and the lower end of the second fixed plate 14 respectively; the top of the second connecting seat 11 is provided with a first fixed plate 10 for fixing the rear end of the second support 8; the rear end of the first fixed plate 10 is connected with a back plate 9.

[0027] As preferred of the above embodiment, it further comprises a walking driving mechanism and a cylinder, the walking driving mechanism is arranged at the bottom of the base 1, for pushing the base 1 to move on the slide rail 2; the cylinder is arranged at the rear of the base 1, for pushing the first support 3 and the second support 8 to move relative to the base 1 as a whole.

[0028] As preferred of the above embodiment, the top of the front end of the base 1 is provided with a first connecting seat 5 on both sides, a first rotation shaft 4 is rotationally installed between the first connecting seats 5, and the front end of the first connecting seat 5 is rotationally connected with the front end of the first support 3 through the first rotation shaft 4.

[0029] As preferred of the above embodiment, as Figure 4 As shown, the first rotation connecting arm 12 and the third rotation connecting arm 13 are both double rotation arm structures which can rotate in the middle, which can further adjust the posture while ensuring that the back plate 9 can recline backward, reduce the included angle of the back plate 9 and the first support 3 and the second support 8 as a whole, and further improve the lying comfort.

[0030] As preferred of the above embodiment, the first support 3 and the second support 8 are detachably connected through bolts, which facilitates the disassembly and maintenance of the first support 3 and the second support 8.

[0031] The specific working principle of the application is as follows: when the seat is flat, the front end of the first support 3 and the second support 8 as a whole is rotated around the first connecting seat 5 through the first rotating shaft 4, and the rear end is rotated around the bottom seat 1 rear end through the first rotating connecting arm 6 and the second rotating shaft 7; since the first rotating connecting arm 6 is arranged, the height of the rear end of the first support 3 and the second support 8 as a whole is lower than the height of the front end, the structure can make the leg and knee naturally bent, and the comfort is improved; meanwhile, the two ends of the second rotating connecting arm 12 are respectively connected with the front end of the second connecting seat 11 and the upper end of the second fixed plate 14; the two ends of the third rotating connecting arm 13 are respectively connected with the rear end of the second connecting seat 11 and the lower end of the second fixed plate 14; when the back plate 9 is adjusted, the back plate 9 is first inclined backward; since the second rotating connecting arm 12 and the third rotating connecting arm 13 adopt the double rotating arm structure, in the rear end stroke of the back plate 9 when the back plate 9 is inclined backward, the bottom is closer to the rear end of the bottom seat 1, and the included angle of the backrest and the cushion mounted on the back plate 9 of the existing automobile electric seat is smaller, the hip feeling of the included angle position when flat is reduced, and the flat is more comfortable.

[0032] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not the limitation of the embodiments of the utility model. For ordinary skilled in the art, other different forms of changes or variations can be made on the basis of the above description. Here, all the embodiments are not required to be exhausted. Any modification, equivalent replacement and improvement within the spirit and principle of the utility model should be included in the protection scope of the utility model claim.
