Embodiment 1

[0047] figure 1 It is a schematic structural diagram of a seat lumbar support adjusting device provided in the first embodiment of the present invention, such as figure 1 As shown, the adjusting device includes: a backrest pressure sensor 110, a controller 120, and an electric lumbar support 130;

[0048] The backrest pressure sensor 110 is electrically connected to the controller 120, and the controller 120 is electrically connected to the electric lumbar support 130.

[0049] The backrest pressure sensor 110 is used to obtain the current pressure distribution data curve of the occupant on the seat back. The controller 120 is configured to compare the current pressure distribution data with a preset seat comfort pressure distribution model curve to obtain difference data, and control the electric lumbar support to adjust the current position according to the difference data. The electric lumbar support 130 is used to adjust the current position under the control of the controller....

Embodiment 2

[0053] Figure 4 It is a schematic structural diagram of a seat lumbar support adjusting device provided in the second embodiment of the present invention. In this embodiment, preferably, the backrest pressure sensors 110 are distributed along the profile of the backrest. Specifically, the backrest pressure sensors are distributed in a strip or sheet shape.

[0054] Such as Figure 4 As shown, the backrest pressure sensor 110 includes a plurality of sensing points 111 and a data processing unit 112.

[0055] Each sensing point 111 is electrically connected to the data processing unit 112.

[0056] The sensing point 111 is used to detect the current pressure value of the corresponding position. The data processing unit 112 is configured to draw the current pressure value detected by each sensing point 111 into a current pressure distribution data curve.

[0057] In practical applications, the backrest pressure sensor 110 may be distributed in strips or sheets along the backrest profil...

Embodiment 3

[0064] Figure 5 This is a schematic flow chart of the method for adjusting the seat lumbar support provided in the third embodiment of the present invention, such as Figure 5 As shown, including the following steps:

[0065] S501. The backrest pressure sensor acquires the current pressure distribution data curve of the occupant on the seat back.

[0066] S502: The controller compares the current pressure distribution data with the preset seat comfort pressure distribution model curve, obtains the difference data, and controls the electric lumbar support to adjust the current position according to the difference data.

[0067] S503. The current position of the electric lumbar support is adjusted under the control of the controller.

[0068] In practical applications, the execution body of this method can be the seat lumbar support adjustment device. In order to obtain the back pressure data of the occupant, the backrest pressure sensor can be arranged between the seat back foam and th...

Abstract

The invention discloses a seat waist support adjusting device and method and a seat. The seat waist support adjusting device comprises a backrest pressure sensor, a controller and an electric waist support. The backrest pressure sensor is electrically connected with the controller, and the controller is electrically connected with the electric waist support. The backrest pressure sensor acquires acurrent pressure distribution data curve of a passenger on a seat backrest, the controller compares current pressure distribution data with a preset seat comfort pressure distribution model curve toobtain difference data and controls the electric waist support to adjust the current position according to the difference data, and the electric waist support adjusts the current position under the control of the controller. In the scheme, the electric waist support is actively controlled to adjust the current position in order to meet the demand of the passenger for comfort, and the passenger hasno need to carry out passive adjustment according to her / his feeling and is prevented from making improper adjustment. Timeliness of the adjustment of the waist support is realized, and the accuracyof the adjustment of the waist support is improved.

Description

Technical field [0001] The invention relates to the technical field of automobile manufacturing, in particular to a seat lumbar support adjustment device, method and seat. Background technique [0002] In car seats, more and more models are equipped with manual or electric lumbar support, which supports the driver's waist through lumbar support adjustment to ensure driving comfort. The traditional manual or electric lumbar support mainly uses the driver's own feelings for passive adjustment, which has serious hysteresis. Inappropriate adjustment will increase the driver's fatigue, especially during long-distance driving. [0003] Therefore, how to realize the real-time adjustment of the lumbar support and improve the accuracy of the lumbar support adjustment is an urgent technical problem in this field. Summary of the invention [0004] In view of this, the embodiments of the present invention provide a seat lumbar support adjustment device, method, and seat, so as to achieve real-...
