[0001] The utility model relates to the technical field of automobile seats, in particular to a backrest frame of an automobile seat. Background Art

[0002] With the popularization of automobiles and the development of science and technology, the safety performance, handling performance and comfort of automobiles have been greatly improved. Among them, car seats are the most direct reflection of car comfort. Car seats can be divided into front seats and rear seats. The front seats include headrests, backrests and seat cushions, and the rear seats include headrests, backrests, seat cushions, side wings, armrests, etc.

[0003] Existing car seats are designed in accordance with ergonomics. The seat backs are set in a raised shape to fit the waist position of the passengers, thereby achieving better support. However, people have different heights, so the waist position is also different, which reduces the riding experience of the seat. There is room for improvement. Utility Model Content

DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0023] The utility model provides a technical solution: Figure 1 , Figure 3 and Figure 4 As shown, in this embodiment, the car seat back frame includes a frame body 1, which is characterized in that: an adjustment component 5 is installed inside the frame body 1, and the adjustment component 5 includes two mounting grooves 501 opened on the outer wall of one end of the frame body 1, and the two mounting grooves 501 are respectively located on both sides of the frame body 1, and a mounting block 504 is slidably connected in the two mounting grooves 501, and a screw rod 502 is threadedly connected in one of the mounting blocks 504, and the two ends of the screw rod 502 are respectively rotatably connected to the top and bottom inner walls of one of the mounting grooves 501, and the other mounting block 504 is slidably inserted with a sliding rod, and the two ends of the sliding rod are respectively fixedly connected to the top and bottom inner walls of the other mounting groove 501, and a motor 503 is installed inside the frame body 1, and the rotating shaft of the motor 503 and one end of the screw rod 502 are coaxially fixed.

[0024] The two mounting blocks 504 are installed with the same telescopic assembly 6, which includes four rotating sleeves 601 rotatably connected to the outer wall of one end of the two mounting blocks 504, and each of the four rotating sleeves 601 is threadedly connected with a screw rod 602, and one end of the four screw rods 602 is fixedly connected to the same supporting block 606.

[0025] The outer walls of the four rotating sleeves 601 are fixed with a gear ring 603, and the outer walls of one end of the two mounting blocks 504 are fixed with a motor 2 604. The rotating shafts of the two motors 604 are coaxially fixed with a gear 605, and two gear rings 603 on one side are respectively meshed with the two gears 605.

[0026] If it is necessary to adjust the longitudinal position of the support block 606, just start the motor 503 to drive the screw rod 502 to rotate in the installation groove 501, and the installation block 504 restricted by the installation groove 501 will move up and down at will under the drive of the screw rod 502, and then the telescopic component 6 and the support block 606 will also change their positions accordingly. If it is necessary to adjust the lateral position of the support block 606, just start the two motors 604 to drive the gear 605 to rotate, and the gear 605 can drive the two rotating sleeves 601 to rotate synchronously through the engagement with the gear ring 603, so as to ensure that the state of the support block 606 is stable enough, and the screw rod 602 is fixed on the outside of the support block 606, and multiple screw rods 602 cooperate with multiple rotating sleeves 601, so as to ensure that the support block 606 cannot rotate. At this time, the rotation of the rotating sleeve 601 can make the whole composed of multiple screw rods 602 and the support block 606 move laterally.

[0027] like Figure 1 and Figure 2As shown, a movable component 7 is installed at the top position of the skeleton body 1, and the movable component 7 includes a mounting hole 701 opened on the outer wall of the top of the skeleton body 1, and the inner walls at both ends of the mounting hole 701 are rotatably connected with a screw rod 3 702, and the screw rod 3 702 is threadedly connected with a mounting block 2 704, and a limit rod 703 is slidably inserted on both sides of the mounting block 2 704, and the two ends of the two limit rods 703 are respectively fixedly connected to the inner walls at both ends of the mounting hole 701.

[0028] The outer wall at one end of the skeleton body 1 is rotatably connected with a knob 3, and the knob 3 and one end of the screw rod 3 702 are coaxially fixed, and the diameter of the knob 3 is larger than the diameter of the screw rod 3 702, so the screw rod 3 702 can be easily controlled to rotate from the outside, which is convenient for operation.

[0029] If the position of the neck support needs to be adjusted, the knob 3 is used to drive a screw rod 3 702 to rotate in the mounting hole 701, and the mounting block 2 704 restricted by the limit rod 703 will be driven by the screw rod 3 702 to move away from or closer to the neck of the occupant, thereby ensuring that the neck support installed on the neck of the mounting block 2 704 can better support the neck of the occupant, which is beneficial to improving the comfort of the backrest.

[0030] like Figure 2 As shown, the top outer wall of the second mounting block 704 is provided with two insertion holes 2, and a locking release assembly can be installed at the top of the insertion hole 2, thereby achieving the effect of limiting the neck leaning in the insertion hole 2.

[0031] like Figure 1 As shown, a plurality of equidistantly distributed reinforcement rods 4 are fixedly connected to the inner walls on both sides of the skeleton body 1 , which can increase the overall strength of the skeleton body 1 .

[0032] The utility model provides a car seat back frame, and the specific working principle is as follows:

[0033] When the device is working, if the longitudinal position of the support block 606 needs to be adjusted, the motor 1 503 is started to drive the screw rod 1 502 to rotate in the installation groove 501, and the installation block 1 504 restricted by the installation groove 501 will move up and down at will under the drive of the screw rod 1 502, and then the telescopic component 6 and the support block 606 will also change their positions accordingly. If the lateral position of the support block 606 needs to be adjusted, the two motors 2 604 are started to drive the gear 605 to rotate. The gear 605 can drive the two rotating sleeves 601 to rotate synchronously by meshing with the gear ring 603, so as to ensure that the state of the support block 606 is sufficiently stable, and the screw rod 2 602 is fixed. It is fixed outside the support block 606, and multiple screw rods 602 cooperate with multiple rotating sleeves 601 to ensure that the support block 606 cannot rotate. At this time, the rotating sleeve 601 can rotate to make the whole composed of multiple screw rods 602 and the support block 606 move laterally. When in use, if the position of the neck support needs to be adjusted, just drive a screw rod 3 702 to rotate in the mounting hole 701 through the knob 3, and the mounting block 2 704 restricted by the limit rod 703 will be driven by the screw rod 3 702 to move away from or close to the neck of the occupant, so as to ensure that the neck support installed on the neck of the mounting block 2 704 can better support the neck of the occupant, which is beneficial to improving the comfort of the backrest.
