[0024] A first embodiment of the present invention relates to a vehicle seat back adjustment method. Figure 1 is a schematic diagram of a vehicle seat back adjustment system according to an exemplary embodiment. Figure 1 As shown, the vehicle seat back adjustment system includes: a back telescopic adjustment device, a back telescopic adjustment drive member and a back angle adjustment device; The backrest telescopic adjustment driving member and the backrest telescopic adjustment device are installed inside the backrest of the vehicle seat, the backrest telescopic adjustment driving member is connected to the backrest telescopic adjustment device, and one end of the backrest telescopic adjustment device close to the seat cushion of the vehicle seat is connected to the backrest angle adjustment device; The backrest telescopic adjustment driving member telescopically adjusts the backrest through the backrest telescopic adjustment device, and the backrest telescopic adjustment driving member is used to telescopically adjust the backrest according to the pre-acquired angle of the backrest to be adjusted.

[0025] Optionally, the vehicle seat backrest adjustment system further comprises: a backrest angle adjustment driving member, wherein the backrest angle adjustment driving member is mounted on the backrest angle adjustment device; The backrest angle adjustment drive member is used to adjust the backrest angle forward and backward.

[0026] Optionally, the vehicle seat back adjustment system further includes: a back angle adjustment switch and a seat control module; The backrest angle adjustment switch includes an internal switch circuit, and the internal switch circuit is communicatively connected with the seat control module.

[0027] Optionally, the backrest telescopic adjustment drive component includes a backrest telescopic position detection module; the backrest telescopic position detection module is communicatively connected to the seat control module.

[0028] Optionally, the backrest angle adjustment drive component includes a backrest angle position detection module; the backrest angle position detection module is communicatively connected to the seat control module.

[0029] Optionally, the backrest telescopic adjustment driving member is fixedly installed at a preset position inside the backrest, and the backrest telescopic adjustment driving member and the backrest are relatively stationary.

[0030] Optionally, the backrest telescopic adjustment device is parallel to the backrest.

[0031] It should be noted that in the embodiments of the present application, the purpose of the present invention is to provide a vehicle seat back adjustment system to ensure that the passenger can always maintain a comfortable position before, during and after the back adjustment, solve the problem that the passenger needs to readjust the sitting posture or adjust the height of the seat headrest after the back adjustment, and let the passenger have a better seat experience. To achieve the above purpose, the vehicle seat back adjustment system includes: a back angle adjustment drive, a back angle position detection module, a back telescopic adjustment device, a back telescopic adjustment drive, a back telescopic position detection module, a back angle adjustment switch, a seat control module, and a seat.

[0032] Among them, the seat includes a seat cushion and a backrest.

[0033] It should be noted that there is no requirement for the installation location of the seat control module. For example, it can be installed inside the seat cushion. The seat control module can then receive external instructions, for example, the user manually adjusts the seat back through a switch.

[0034] Specifically, for example, Figure 1 , Figure 1 The middle backrest telescopic adjustment device can be a sliding track, the backrest angle adjustment device can achieve backrest front and rear angle adjustment through a rotating shaft, and the backrest telescopic adjustment drive member can be a drive motor.

[0035] Therefore, the backrest angle adjustment mainly completes the front and rear angle adjustment of the backrest, including the objects installed on the backrest; the backrest telescopic adjustment drive is installed in the backrest and fixed in a position, and is relatively stationary with the backrest position; the backrest telescopic adjustment device is parallel to the backrest and is located in the backrest, and moves with the backrest telescopic adjustment drive by gears. The motor will not deviate from the track, and the sliding track does not directly contact the backrest. It is welded to the fixed position of the backrest angle adjustment device near the seat cushion end, and performs angular movement with the backrest; the telescopic movement of the backrest is completed by the backrest telescopic adjustment drive carrying the entire backrest to move on the backrest telescopic adjustment device.

[0036] It should be noted that Figure 1 This is just an example, and does not limit the telescopic adjustment of the backrest to use a slide rail or a slide rail motor, as long as the seat back can be telescoped in coordination according to the angle.

[0037] The motors used for the fore-and-aft angle adjustment and telescopic adjustment of the backrest have the characteristics of forward and reverse direction control and torque control; the fore-and-aft angle adjustment position of the backrest is sensed in real time, and the telescopic position of the backrest is sensed in real time; and when the angle between the seat cushion and the backrest is greater than 90°, a relationship between the angle and the backrest stroke is calibrated in advance to establish one or more mathematical equations or logical relationships; the seat controller establishes another equation or logical relationship based on the relationship between the power output and movement angle of the backrest adjustment motor, and the relationship between the power output and movement stroke of the backrest telescopic motor, and drives the two motors to move simultaneously at the initial stage of backrest adjustment; during the movement process, based on the angle feedback of the seat back operation and the telescopic position feedback of the backrest, the controller performs fine-tuning of the backrest telescopic control according to the pre-set angle and backrest stroke relationship, and ultimately achieves that the relative position of the human body remains unchanged before, during, and after the backrest adjustment, so that passengers have a comfortable adjustment experience.

[0038] Specifically, for the backrest angle adjustment switch, the backrest angle adjustment switch can be a self-resetting switch. Specifically, when the switch is in use, only one of the front and rear switches can be pressed at the same time, and they cannot be pressed at the same time. The internal circuit of the switch is connected to the controller. According to the internal circuit and interface requirements of the controller, resistive switches, blocking switches and other forms are provided. In the embodiment of the present application, a blocking switch can be used; the controller provides two low-voltage digital detection circuits and a common ground (GND). The front and rear adjustment switches of the backrest share a ground, which are respectively connected to the two low-voltage digital detection circuits of the controller. When one of the switches is pressed, the circuit forms a path, and the low-voltage digital detection of the controller can detect a ground through this path to trigger the function to be turned on.

[0039] Specifically, the backrest telescopic adjustment drive and the backrest angle adjustment drive both have high-frequency PWM bridge drive capabilities, and the corresponding controllers also have output capabilities. The controller uses PWM to control the speed of the motor, and the bridge drive circuit of the controller controls the direction of motor movement. The motor has a position detection module inside, which can feed back the position and number of turns of the motor to the controller through the interface.

[0040] Furthermore, the method of controlling the motor is not limited to a single method. It can be input by operating the adjustment switch on the seat, input through voice control request, input through the touch screen switch on the central control screen, or input through a mobile phone. That is, the seat control module can control the motor according to the received external instructions.

[0041] Furthermore, there is no restriction on the control method of the motor. For example, a bridge drive with PWM control output or other methods can be used, as long as the movement of the motor can achieve controllable direction, telescopic adjustment, and speed of the backrest.

[0042] The vehicle seat back adjustment system of the present invention comprises: a back telescopic adjustment device, a back telescopic adjustment driving member and a back angle adjustment device; the back telescopic adjustment driving member and the back telescopic adjustment device are installed inside the back of the vehicle seat, the back telescopic adjustment driving member is connected to the back telescopic adjustment device, and one end of the back telescopic adjustment device close to the seat cushion of the vehicle seat is connected to the back angle adjustment device; the back telescopic adjustment driving member telescopically adjusts the backrest through the back telescopic adjustment device, and the back telescopic adjustment driving member is used to telescopically adjust the backrest according to the pre-acquired angle to be adjusted of the backrest. The seat back adjustment system of the embodiment of the present invention integrates the back telescopic adjustment driving member, the back telescopic adjustment device and the back angle adjustment device, and at the same time as the back angle is adjusted, the backrest is moved by the back telescopic adjustment driving member and the back telescopic adjustment device to ensure that the position of the backrest before, during and after the adjustment is consistent, ensuring that the passenger always maintains a comfortable sitting posture during the entire adjustment process, without the need to readjust the sitting posture or the headrest height, thereby significantly improving the passenger's seat experience.

[0043] A second embodiment of the present invention relates to a vehicle seat back adjustment method. Figure 3 is a device block diagram of a vehicle seat back adjustment device according to an exemplary embodiment. Figure 3 As shown, the method includes: Step 101, when it is detected that the backrest angle adjustment switch is in an adjustment state, determining the to-be-adjusted angle corresponding to the backrest according to the adjustment angle received in advance from the user; Step 102, calculating the distance to be extended and retracted corresponding to the backrest according to the preset ratio between the adjustment angle and the extension and retraction distance of the backrest and the angle to be adjusted; Step 103, adjusting the backrest according to the angle to be adjusted and the distance to be extended and retracted.

[0044] Further, adjusting the backrest according to the angle to be adjusted and the distance to be extended and retracted comprises: Controlling a backrest angle adjustment driving member and a backrest telescopic adjustment driving member based on the angle to be adjusted and the telescopic distance to be extended; The target backrest angle position is monitored in real time by the backrest angle position detection module in the backrest angle adjustment drive component, and the backrest is adjusted according to the target backrest angle position and the angle to be adjusted. Also, the target telescopic stroke position is monitored in real time by the backrest telescopic position detection module in the backrest telescopic adjustment drive component, and the backrest is telescopically adjusted according to the target telescopic stroke position and the distance to be telescopic.

[0045] It should be noted that in the embodiment of the present application, when the passenger uses the backrest angle adjustment switch, the seat control module receives a digital or a continuous digital ground, and the controller determines the direction and time of the passenger backrest adjustment. At the same time, the seat module needs to calculate the angle and distance that the seat back needs to be adjusted up and down according to the current front and rear position of the backrest, the telescopic stroke position, and the pre-designed ratio of the backrest angle and the telescopic stroke to simultaneously control the backrest angle adjustment drive and the backrest telescopic adjustment drive; at the same time, the backrest angle position and the telescopic stroke position can be monitored in real time by the backrest angle position detection module and the backrest telescopic position detection module. After collecting the two feedback values, the seat telescopic adjustment is fine-tuned according to the calibrated front and rear angle and position stroke data; the parallel slide rail motor moves along the backrest telescopic adjustment device, which will drive the entire backrest to move on the parallel slide rail, so that the relative position of the backrest to the human body remains unchanged before, during, and after the adjustment, so that the passenger has a comfortable adjustment experience.

[0046] Specifically, refer to Figure 2 , Figure 2 The figure is a schematic diagram of the connections between the overall functional modules. Figure 2 It can be concluded that the adjustment of the overall seat includes the following steps: First, input signal reception: the passenger uses the backrest angle adjustment switch. The seat control module receives a digital or a continuous digital signal.

[0047] Second, controller judgment: The controller judges the direction and time of passenger backrest adjustment based on the received signal.

[0048] Third, calculate the adjustment parameters: The seat module calculates the angle and distance that the seat back needs to be adjusted up and down based on the current fore-and-aft position and telescopic stroke position of the backrest, according to the pre-designed ratio of the backrest angle and telescopic stroke.

[0049] Fourth, motor control: simultaneously control the backrest angle adjustment drive and the backrest telescopic adjustment drive.

[0050] Fifth, real-time monitoring and feedback: The backrest angle position and telescopic travel position are monitored in real time through the backrest angle position detection module and the backrest telescopic position detection module. In addition, the two feedback values ​​are collected, and the seat telescopic adjustment is fine-tuned according to the calibrated front and rear angle and position travel data.

[0051] Sixth, parallel slide motor movement: the parallel slide motor moves along the backrest telescopic adjustment device, driving the entire backrest to move on the parallel slide rail, so that the relative position of the human body remains unchanged before, during and after the backrest adjustment.

[0052] The embodiment of the present invention integrates a backrest telescopic adjustment drive component, a backrest telescopic adjustment device and a backrest angle adjustment device. While adjusting the backrest angle, the backrest is moved by the backrest telescopic adjustment drive component and the backrest telescopic adjustment device to ensure that the position of the backrest remains consistent before, during and after adjustment, ensuring that the passenger always maintains a comfortable sitting posture during the entire adjustment process without having to readjust the sitting posture or headrest height, thereby significantly improving the passenger's seat experience.

[0053] In addition, the embodiments of the present application ensure that when the passenger adjusts the fore and aft angle of the backrest, the seat can automatically adjust to a preset comfortable position through real-time monitoring and precise calculation, without the need for the passenger to manually readjust the sitting position or headrest height, thereby maintaining the passenger's comfort experience throughout the entire adjustment process, significantly improving the intelligence of the seat and user experience.

[0054] A third embodiment of the present invention relates to a vehicle seat back adjustment device, Figure 4 is a device block diagram of a vehicle seat back adjustment device according to an exemplary embodiment.

[0055] The embodiment of the present invention integrates a backrest telescopic adjustment drive component, a backrest telescopic adjustment device and a backrest angle adjustment device. While adjusting the backrest angle, the backrest is moved by the backrest telescopic adjustment drive component and the backrest telescopic adjustment device to ensure that the position of the backrest remains consistent before, during and after adjustment, ensuring that the passenger always maintains a comfortable sitting posture during the entire adjustment process without having to readjust the sitting posture or headrest height, thereby significantly improving the passenger's seat experience.
