Description

Technical Field

[0001] This invention belongs to the field of automotive safety, and in particular relates to an automotive seat safety adjustment system and adjustment method. Background Technology

[0002] With the booming development of the automotive industry, car seats are no longer just simple seating components; their role in passenger comfort and safety is becoming increasingly prominent. Modern car seats are designed and manufactured in strict accordance with safety standards and regulations, undergoing crash tests and simulation experiments to verify their safety performance. The seat frame structure is made of high-strength materials, effectively absorbing and dispersing impact forces during a collision to protect passengers from injury. Furthermore, the seats are equipped with various safety features, such as headrests, side airbags, and whiplash protection, further enhancing passenger safety. It is evident that with the continuous development of the automotive industry, car seats are playing an increasingly important role in passenger comfort and safety. In the future, with continuous technological advancements and innovation, car seats will continue to evolve towards greater intelligence, personalization, and safety.

[0003] Currently, traditional car seat adjustment systems generally rely on manual operation or simple electric adjustment mechanisms. While these systems offer some possibility of seat position adjustment, they often encounter problems with slow and inaccurate adjustments in actual use. This often results in passengers, especially drivers, spending a lot of time trying to find the most comfortable seating position, and may even affect driving comfort and safety due to improper adjustments. Even if the driver has found a relatively satisfactory position during seat adjustment, the comfort of the seat may change once they change their shoes or clothing, or even just adjust their posture. This is because traditional seat adjustment systems cannot sense and adapt to changes in the passenger's body in real time. This lack of adaptability means that drivers may need to constantly adjust the seat while driving, which not only distracts them but may also increase the risk of accidents due to distracted operation. Furthermore, the act of adjusting the seat while driving itself harbors safety hazards. When adjusting the seat, drivers often need to divert their attention to manually operate adjustment buttons or levers, which may reduce their focus on the road ahead, thus increasing the likelihood of accidents. This risk of distracted operation is particularly significant at high speeds or in complex road conditions.

[0004] It is evident that existing seat adjustment systems rely on manual or simple electric adjustments, making it difficult to quickly and accurately adjust the seat to a comfortable position. Summary of the Invention

[0027] The seat adjustment mechanism automatically adjusts the height, fore-aft position, and backrest tilt angle of the car seat based on received signals such as seat height adjustment, seat forward movement, seat backward movement, and seat back tilt.

[0028] Furthermore, it also includes:

[0029] The data processing unit compares the pedal pressure data with the preset pedal pressure reference value. If it is greater than the preset pedal pressure reference value, the control unit and seat adjustment mechanism adjust the car seat to tilt backward; otherwise, the car seat is adjusted forward and downward.

[0030] The data processing unit makes a judgment based on the steering wheel pressure data. If it determines that the steering wheel is being pushed forward, it adjusts the car seat to move backward; otherwise, it moves it forward.

[0031] Furthermore, the data processing unit makes a judgment based on the steering wheel pressure data. If it determines that the steering wheel is being pulled outward, it expands the side bolster of the car seat; otherwise, it contracts the side bolster of the car seat.

[0054] Example 1

[0055] As mentioned in the background technology, each time a driver gets into the car or drives, due to changes in personal clothing or physical condition such as shoes or clothes, they cannot quickly and safely adjust to a suitable sitting or driving posture and need to repeatedly adjust the seat. Traditional seat adjustment involves passengers directly controlling the seat through physical buttons, or there are methods that directly control the seat using mechanical structures. When adjusting, passengers must operate directly with their hands, and it takes multiple adjustments to reach a comfortable position. Even after returning to a normal sitting posture, the passenger may still feel uncomfortable.

[0056] To address the aforementioned problems, this invention provides a car seat safety adjustment system and method. This system and method replace manual adjustment with contactless force adjustment, allowing for subtle adjustments to seating posture without manual intervention during driving, enabling occupants to quickly adjust to a comfortable sitting position.

[0057] like Figure 1 As shown, this embodiment provides a car seat safety adjustment system, including a sensor unit for collecting body characteristic data of passengers; a data processing unit for processing the body characteristic data and generating and outputting data processing results; a control unit for generating and outputting seat adjustment signals based on the received data processing results; and a seat adjustment mechanism for automatically adjusting the car seat based on the received seat adjustment signals.

[0058] Specifically, for each of the above functional units, the embodiments provide the following preferred hardware components:

[0059] The sensor unit employs body feature sensors, specifically including:

[0060] Pressure sensors (rest pedal pressure sensor 1, steering wheel touch sensor 2, and seat pressure sensor 3): can be installed on the seat cushion and backrest, as well as the foot pedal, to detect the passenger's weight distribution and sitting posture.

[0061] Infrared sensor: By scanning the passenger's body outline, information such as the passenger's height and body shape can be obtained.

[0062] Optical sensors or cameras: Combined with image processing technology, they can further analyze passengers' body shape and posture.

[0063] Data processing unit:

[0064] Central processing unit (CPU) or microcontroller: responsible for receiving sensor data, executing preset algorithms or models to process the data, and outputting adjustment suggestions or instructions.

[0065] Non-volatile data storage: Used to store preset algorithms, models, passenger preferences and other data, and to keep the data from being lost when the system is powered off.

[0066] Interface circuit: responsible for converting sensor data from analog signals to digital signals and transmitting them to the CPU for processing; at the same time, it converts the instructions output by the CPU into control signals and transmits them to the control unit.

[0067] Control unit:

[0068] Motor drive circuit: Based on instructions output by the CPU, this circuit drives the motor of the seat adjustment mechanism. This typically includes a PWM (Pulse Width Modulation) control circuit to adjust the motor's speed and direction.

[0069] Safety logic circuit: It contains some preset safety limits, such as maximum adjustment range and minimum adjustment time interval, to ensure that the seat adjustment does not exceed the safe range or damage the seat mechanism.

[0070] Communication interface: Communicates with the CPU, receives instructions, and sends feedback signals to the CPU. This typically uses serial communication protocols such as SPI or I2C.

[0071] Seat adjustment mechanism:

[0072] DC motor: Drives various parts of the seat to move according to instructions from the control unit. This includes adjustments such as the seat's forward / backward movement, up / down position, and backrest angle.

[0073] Transmission devices, such as worm gears, racks and pinions, are used to convert the rotary motion of the motor into the linear or rotary motion of the seat.

[0074] Position sensors, such as Hall effect sensors or photoelectric encoders, are used to detect the actual position of the seat in real time and feed the position information back to the control unit.

[0075] The aforementioned hardware components together form the physical basis of the automatic car seat adjustment system. Through their collaborative work, they enable intelligent perception and automatic adjustment of passenger body characteristic data.

[0076] This embodiment provides a car seat safety adjustment system, and the adjustment method is as follows:

[0077] The system collects foot pressure data, steering wheel pressure data, and seat back pressure data of passengers through rest pedal pressure sensor 1, steering wheel touch sensor 2, and seat pressure sensor 3, respectively.

[0078] The data processing unit compares and judges the foot pedal pressure data, steering wheel pressure data, and seat back pressure data with the corresponding preset pressure values, and generates and outputs the seat height adjustment result or seat low adjustment result, seat forward movement result or seat backward movement result, and seat back forward tilt result or seat back tilt result respectively.

[0079] The control unit generates and outputs a seat height adjustment signal or a seat low adjustment signal, a seat forward movement signal or a seat backward movement signal, and a seat back tilt signal or a seat back tilt signal based on the seat height adjustment result or seat low adjustment result, seat forward movement signal or seat backward movement signal, and seat back tilt signal or seat back tilt signal.

[0080] The seat adjustment mechanism automatically adjusts the height, fore-aft position, and backrest tilt angle of the car seat based on received signals such as seat height adjustment, seat forward movement, seat backward movement, and seat back tilt.

[0081] In this embodiment, the more specific adjustment steps are as follows:

[0082] Among them, such as Figure 2 As shown, the body feature sensors in the sensor unit include a rest pedal pressure sensor 1, a steering wheel touch sensor 2, and a seat pressure sensor 3. The specific steps are as follows:

[0083] Step 1, activation conditions: The vehicle is unlocked and powered on, and the seat pressure sensor 3, steering wheel touch sensor 2, and rest pedal pressure sensor 1 detect the correct values;

[0084] The second step, as Figure 2 As shown, Figure 2 The rest pedal is equipped with a pedal pressure sensor 1. The pressure data collected by the pedal pressure sensor 1 can control the up and down movement of the seat. When the pedal is pressed hard, the seat moves diagonally backward (i.e., it is judged by the preset pressure reference value). When the force applied is small or there is no force, the seat moves slowly forward and downward.

[0085] Third, when adjusting the seat, if the steering wheel touch sensor 2 does not detect the correct hand grip posture, the steering wheel vibrates as a reminder, and the vehicle system prompts the driver to grip the steering wheel correctly.

[0086] Fourth, the steering wheel is equipped with a steering wheel pressure sensor (which can also be integrated with the steering wheel touch sensor 2). The driver can control the adjustment of the seat by applying pulling or pushing force, including but not limited to: pulling the steering wheel outward to expand the side bolster of the seat; squeezing the steering wheel inward to shrink the side bolster of the seat; pushing the steering wheel forward to move the seat backward; and pulling the steering wheel backward to move the seat forward.

[0087] The fifth step involves installing a seat pressure sensor 3 on the seat. The angle of the seat back is adjusted by the passenger leaning back and applying pressure to the backrest. When the seat pressure sensor 3 collects a backrest pressure data of 0, it indicates that the passenger's back is not in close contact with the backrest. Therefore, the tilt angle is adjusted so that the backrest is closer to the passenger and supports the passenger's back. When the passenger presses their back against the backrest, the collected backrest pressure data gradually increases and the tilt angle is adjusted. When the passenger feels comfortable at a certain moment, the position can be locked through the next step.

[0088] The sixth step is to end and save the seat adjustment position by using the button on the steering wheel (seat status lock unit). In other words, the adjustment system automatically adjusts until the pressure data is in a stable state (i.e., the passenger is in a comfortable state), and then locks the state through the seat status lock unit. This allows the system to lock the seat state after the seat adjustment is completed, preventing changes in seat position due to accidental touch or vehicle bumps. This function ensures the stability and reliability of seat adjustment.

[0089] Example 2

[0090] This system also provides another car seat safety adjustment system, such as Figure 2 As shown, this system has the same basic structure as the system provided in Embodiment 1. Based on Embodiment 1, the system has been further optimized, specifically including:

[0091] The system also includes a memory unit for storing the adjusted seat status and associating it with frequently used passenger information. When adjusting the seat later, the memory unit can retrieve the corresponding seat status based on the frequently used passenger information to control the seat adjustment mechanism to complete the adjustment. The introduction of the memory unit allows the system to store the seat preferences of frequently used passengers and automatically adjust the seat to the appropriate position when the passenger rides again. This function improves the passenger's riding experience and increases the system's intelligence and personalization.

[0092] In addition, the sensor unit may also include a vehicle driving status sensor, with the following specific structure:

[0093] Vehicle speed sensor: Directly reads the vehicle's CAN bus data to obtain the current vehicle speed.

[0094] Accelerometer: Installed in key locations on the vehicle, such as under the chassis or seats, to detect the vehicle's acceleration and vibration.

[0095] Steering angle sensor: mounted on the steering column or steering wheel, used to detect the vehicle's steering angle and turning radius.

[0096] The vehicle driving status sensor mentioned above is used to collect the current driving status of the vehicle, such as the vehicle's gear status, speed status, and road conditions (turning, lane changing), etc. The data processing unit judges the current status, effectively correlates it with body feature data, and outputs a comprehensive data processing result. This adjustment method that combines the vehicle driving status ensures a better seat adjustment effect and enhances the user's driving and riding experience.

[0097] In summary, this invention provides a car seat safety adjustment system and method, which has the following advantages compared to existing ceramic pad molding and testing methods:

[0098] This invention provides a car seat safety adjustment system. Through various sensors built into the steering wheel, rest pedals, and seat, it allows for quick, convenient, and accurate adjustment to a suitable position without manual operation of buttons. This system is applicable to scenarios where passengers, especially drivers, cannot quickly and safely adjust to a comfortable seating or driving posture due to changes in personal clothing or physical condition after each entry or drive, requiring repeated seat adjustments. Traditional seat adjustments involve passengers directly controlling the seat with physical buttons, or sometimes using mechanical structures. These methods require manual operation, necessitate multiple adjustments to achieve a comfortable position, and discomfort may persist even after returning to a normal sitting posture. Therefore, this invention proposes a new seat safety adjustment system that replaces manual adjustment with contactless force adjustment, allowing for minor adjustments to the seating posture without manual intervention during driving, enabling passengers to quickly adjust to a comfortable position.

[0099] The above embodiments are merely one of the implementation methods for achieving the technical solution of the present invention. The scope of protection claimed by the present invention is not limited to this embodiment, but also includes any variations, substitutions and other implementation methods that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention.
