Description

Technical Field

Car seats, as an important part of the whole vehicle, are no exception. People are no longer satisfied with simple seats, but require seats to provide a more comfortable and safe experience. Therefore, in order to reduce the fatigue caused by long-term driving and riding, lumbar supports are usually installed on car seats.

[0003] However, the existing automobile seats with lumbar supports have some problems in actual working process. For example, a car seat structure with adjustable lumbar support position, which is published as CN113954712B, has a relatively single function in working process. Although the height of the air bag lumbar support can be adjusted and the air volume in the air bag lumbar support can be adjusted by using an air valve, it does not have a memory function when inflating the air bag lumbar support. Therefore, when the air bag lumbar support is inflated and used, it cannot maintain the same inflation state according to the driver's setting. Therefore, the driver needs to frequently adjust the inflation volume of the air bag lumbar support when driving multiple times; and it cannot adjust and support the side waist of the passenger according to actual needs and the body shape of the passenger, and it cannot automatically massage the waist of the passenger.

[0029] It should be noted that the present invention is a car seat with a pneumatic lumbar support. First, under the driving action of the hydraulic rod 814 on the second fixing rods 813 on both sides, the push plates 815 on both sides can be driven to move toward the middle, and then each plug rod 805 can be pushed to move into the corresponding air storage frame 802 and move to the limit distance. At this time, under the driving action of the plug rod 805, the air stored in the air storage frame 802 can be pushed into each first lumbar support airbag 12 through the fourth air pipe 816 through the rubber piston 804, and the first lumbar support airbag 12 transports the air to the second lumbar support airbags 16 on both sides through the hose 15, completing the simultaneous inflation of each first lumbar support airbag 12 and the corresponding second lumbar support airbag 16. Subsequently, under the driving action of the small air pump 806, the air can be pumped into the airbag 12 through the first air pipe 816. 807 inflates the first air guide frame 808, and by opening the solenoid valve 810 on the second air pipe 809 at the top, the two air storage frames 802 at the top can be inflated through the second air guide frame 811 at the top and the third air pipes 812 on both sides, and then the air can be pushed to the first lumbar support airbag 12 at the top and the second lumbar support airbags 16 on both sides through the fourth air pipe 816. After the inflation is completed, the solenoid valve 810 on the second air pipe 809 can be closed. If deflation is required, it is only necessary to open the solenoid valve 810 on the second air pipe 809. Similarly, through the same operation, the inflation volume of the first lumbar support airbag 12 and the corresponding second lumbar support airbag 16 of different heights can be conveniently adjusted, so as to adapt to the waist height of different drivers or passengers, thereby effectively improving the applicability.

[0030] After the inflation amount is adjusted, it is only necessary to drive the push plate 815 on the hydraulic rod 814 to move and disengage from the plug rod 805. At this time, under the elastic action of the first spring 803, the rubber piston 804 can be driven to automatically move to the side, and the internal air of the first lumbar support airbag 12 and the corresponding second lumbar support airbag 16 can be automatically sucked through the fourth air pipe 816 to realize the automatic deflation of the lumbar support, and the adjusted quantitative air is temporarily stored in the air storage frame 802. When the driver or passenger reuses it, it is only necessary to drive the hydraulic rod 814 and drive the push plate 815 to push each rubber piston 804 to the limit distance to automatically complete the quantitative inflation of each first lumbar support airbag 12 and the corresponding second lumbar support airbag 16, so as to realize the memory inflation of the pneumatic lumbar support.

[0031] After the inflation amount is adjusted, the servo motor 901 drives the drive shaft 902 to rotate counterclockwise. Under the counterclockwise rotation of the drive shaft 902, the clamping rod 914 on the third spring 913 can be driven to contact the plane of the clamping block 916. Therefore, the clamping rod 914 can be used to move the sleeve 915 on the clamping block 916 to rotate synchronously. At this time, the sleeve 915 can drive the second bevel gears 918 on both sides through the first bevel gear 917, and then drive the corresponding reciprocating screw rods 919 to rotate at the same time. Under the continuous rotation of the reciprocating screw rods 919 on both sides, the reciprocating threads and the threaded sleeve rod 920 connected by the thread can drive the screw rods on both sides to rotate synchronously. The threaded sleeve rods 920 first move toward the middle at the same time, and after moving to the limit distance, they move toward the sides at the same time. At this time, under the movement of the threaded sleeve rods 920 on both sides, the connecting rods 922 on the rotating seat 921 can push the adjustment plate 924 on the rotating shaft 923 to rotate, and the angle of the adjustment plate 924 can be adjusted. By adjusting the angle of the adjustment plate 924, combined with the inflated second lumbar support airbag 16 and the second silicone plate 17 inside, the side waist of drivers or passengers of different body shapes can be supported, and by separately adjusting the adjustment plates 924 on both sides of the mounting plate 10 of different heights, the body shape and sitting posture requirements of different passengers can be met.

[0032] When the passengers are riding, the servo motor 901 drives the driving shaft 902 to rotate clockwise. At this time, the driving shaft 902 can drive the clamping rod 914 to move in the opposite direction along the inclined surface of the clamping block 916. Therefore, the clamping rod 914 will not drive the sleeve 915 to rotate, and will not affect the adjusted adjustment plate 924. Under the clockwise rotation of the driving shaft 902, the sliding rod 904 can be driven to rotate synchronously through the sliding groove 903, and then the turntable 905 can be driven to rotate stably in the connecting frame 907. At this time, under the rotation of the turntable 905, each top block 906 can be driven to intermittently contact each first push block 909. When the top block 906 contacts the first push block 909, the top block 906 can The first push block 909 can be pushed, and then the second push block 910 can be pushed through the limit rod 908. Under the pushing action of the second push block 910, the waist of the occupant can be massaged through the first lumbar support airbag 12 and the first silicone plate 13. Then, the top block 906 moves away from the first push block 909. At this time, under the elastic action of the second spring 911, the limit rod 908, the first push block 909 and the second push block 910 can be driven to move and reset. In this way, the driver or passenger's waist can be automatically massaged, thereby alleviating the symptoms of waist pain of the driver or passenger; and by separately driving the adjustable massage components 9 on the mounting plates 10 at different heights, different positions of the waist can be massaged according to actual needs.

Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
