[0034] 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.

[0035] 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.

[0036] like Figure 1-Figure 2 As shown, the present application provides a seat lumbar net connection structure, including a seat 1, which is arranged inside a car to provide a riding environment for passengers. The seat 1 includes a base 2, which is fixedly installed inside the car, and a seat cushion 3 is installed on the top of the base 2, which is used for passengers to sit;

[0037] At the same time, two sets of fixing columns 7 are fixedly installed on both sides of the base 2, and the backrest 4 is rotatably connected to the two sets of fixing columns 7. The interior of the backrest 4 is hollow, and a backboard 5 is detachably installed on the back side of the backrest 4. The backboard 5 is fixedly connected to the backrest 4 by a buckle;

[0038] like Figure 2-Figure 5 As shown, in order to allow the user to adjust the lumbar support position according to their body shape and sitting habits, a lumbar support mechanism 6 is detachably installed inside the backrest 4. The lumbar support mechanism 6 includes a bracket 60 fixedly mounted on the back plate 5, a slideway (not shown in the figure) is provided on the bracket 60, and a sliding plate 61 is slidably arranged on the slideway;

[0039] At the same time, a screw rod 62 is rotatably provided between the brackets 60, and a motor 64 is fixedly provided at one end of the bracket 60. The output end of the motor 64 is fixedly connected to the screw rod 62 so as to drive the screw rod 62 to rotate on the bracket 60. At the same time, a screw block 63 is threadedly connected to the screw rod 62, and the screw block 63 is fixedly connected to the sliding plate 61. When the motor 64 is started to drive the screw rod 62 to rotate between the brackets 60, the sliding plate 61 can be driven to move vertically along the slideway on the bracket 60 through the screw block 63.

[0040] A support column 65 is fixedly provided in the middle of the sliding plate 61, and a lumbar support plate 66 is fixedly provided at one end of the support column 65. The lumbar support plate 66 is arranged close to the backrest 4 so as to provide adequate support to the waist during driving and reduce the pressure on the waist when sitting for a long time.

[0041] At the same time, in order to effectively support both sides of the waist during driving, thereby maintaining the stability of the passenger's body and reducing body shaking and discomfort caused by vehicle shaking or sudden braking, side waist support components 67 are hinged on both sides of the sliding plate 61. Figure 5 , the side waist support assembly 67 is used to support both sides of the passenger's waist;

[0042] The side waist support assembly 67 includes a fixed plate 670 hinged on both sides of the sliding plate 61, and a support plate 671 is fixedly provided on the fixed plate 670. The support plate 671 is arranged to fit the side waist of the human body so as to better support the side waist during driving. In addition, a mounting frame 673 is fixedly provided on both sides of the sliding plate 61, and a cylinder 672 is hinged on the mounting frame 673. The output end of the cylinder 672 is hinged to the support plate 671, so that by activating the cylinder 672, the two groups of support plates 671 can be pushed to close toward the center around the sliding plate 61, thereby achieving the effect of fitting the user's waist.

[0043] When adjustment is required, the user can first sit on the seat 1 according to his or her body shape and sitting posture, and then start the motor 64 to drive the lumbar support plate 66 to move vertically along the slide on the bracket 60 through the sliding plate 61 until it is adjusted to the appropriate position and then stop;

[0044] When the side waist needs to be supported, it is only necessary to activate the cylinder 672 to push the support plates 671 on both sides to fit the side waist of the user, thereby achieving the effect of supporting the side waist;

[0045] More preferably, a soft pad can be provided on the inner side of the support plate 671 to improve the hardness when in contact with the waist, thereby improving the comfort of the passenger.

[0046] 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.
