[0002] After the driver sits in the car seat, the seat back and seat cushion will sink in a certain amount. The change in seat shape directly affects the fit between the driver and the seat, and thus affects the comfort of the seat.

[0003] Traditionally, seat comfort is measured primarily by using a dummy to measure the lumbar protrusion of the seat. Based on this lumbar protrusion, it is inferred whether the driver fits well with the seat or floats on the seat surface, resulting in poor fit.

Detailed Implementation

[0049] To make the objectives, technical solutions, and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0050] The seat comfort evaluation method provided in this application embodiment can be applied to, for example, Figure 1 and Figure 2 The seat comfort evaluation system shown. Among them, Figure 1 This is a left-side view diagram of the seat comfort assessment system. Figure 2 This is a front view schematic diagram of a seat comfort assessment system. The system includes a seat mounting frame 100, a seat 200, an auxiliary measuring device 300, a measuring instrument 400, and a processor 500. The seat mounting frame 100 includes a hinged backrest frame 101 and a seat cushion frame 102, with multiple fixed pulleys 103 spaced apart on both sides of the backrest frame 101. The seat 200 includes a backrest 201 and a seat cushion 202, with the backrest 201 mounted on the backrest frame 101 and the seat cushion 202 mounted on the seat cushion frame 102. The auxiliary measuring device 300 includes multiple first wires 301, multiple second wires 302, and multiple weights 303. Each first wire 301 is wrapped around the backrest 201 and passes over the fixed pulleys 103 on both sides of the backrest frame 101 before connecting to form a first end 304. Each first wire 301 has a weight 303 attached to its first end 304 so that the first wire 301 is taut and fits against the backrest 201. Each second wire 302 is wrapped around the seat cushion 202 and passes over the seat cushion frame 102 before connecting to form a second end 305. Each second wire 302 has a weight 303 attached to its second end 305 so that the second wire 302 is taut and fits against the seat cushion 202. The measuring instrument 400 is used to measure the first height value of each weight 303 above the ground in front of the driver sitting in the seat 200, and the second height value of each weight 303 above the ground after the driver sitting in the seat 200. The processor 500 is used to acquire the first height value and the second height value, and to evaluate the comfort of the seat 200 based on the first height value and the second height value.

[0051] The backrest frame 101 has multiple fixed pulleys 103 spaced apart on its left and right sides. The spacing between the fixed pulleys 103 can be set according to the length of the backrest 104. The seat 200 is fixed to the seat fixing frame 100. Since the seat 200 has a certain weight, in practical applications, the seat 200 can be placed directly on the seat fixing frame 100. In the auxiliary measuring device 300, each first thread 301 wraps around the backrest 104 and passes through the fixed pulleys 103 on both sides of the backrest frame 104 before connecting to form a first end 304. A weight 303 is attached to the end of the first end 304. The fixed pulleys 103 guide the threads, ensuring that the weight 303 at the end of the first end 304 is perpendicular to the ground. Since the seat cushion 102 is parallel to the ground, each second thread 302 is also perpendicular to the ground. Thus, the measuring instrument 400 can directly measure the first height value of each weight 303 from the ground before the driver sits on the seat 200, and the second height value of each weight 303 from the ground after the driver sits on the seat 200. The processor 500 obtains the first and second height values ​​from the measuring instrument 400 and can then evaluate the seat comfort based on these values.

[0052] In this embodiment, a seat fixing frame is set up, and the seat is fixed to the seat fixing frame. Multiple threads are used to wrap around the seat and fit against the seat. The two ends of each thread are connected after passing around the seat to form an end. Each end is attached with a weight. A measuring instrument is used to measure the first height value of each weight from the ground in front of the driver when sitting on the seat, and the second height value of each weight from the ground behind the driver when sitting on the seat. The seat comfort is evaluated based on the first height value and the second height value. This can accurately analyze the degree of fit between the seat and various parts of the driver's body, and thus evaluate the seat comfort.

[0053] In one embodiment, such as Figure 1 As shown, the seat fixing frame 100 also includes a hinge mechanism 104, which is located at the connection between the backrest frame 101 and the seat cushion frame 102, and is used to adjust the tilt angle of the backrest frame 101 so that the backrest frame 101 is parallel to the backrest 201 of the seat 200.

[0054] The hinge mechanism 104 is located at the connection between the backrest frame 101 and the seat cushion frame 102. When the seat 200 is placed on the seat fixing frame 100, the seat cushion 202 and the seat cushion frame 102 are parallel to the ground, so they can fit together completely. However, since the backrest 201 has a certain angle, the hinge mechanism 104 is used to adjust the tilt angle of the backrest frame 101 so that the backrest frame 101 is parallel to the backrest 201 of the seat 200 and can fit together completely.

[0055] In this embodiment, by setting a hinge mechanism, the tilt angle of the backrest frame can be adjusted so that the backrest frame is parallel to the back of the seat, which can simulate the seat posture in a real driving environment and is suitable for various types of seats.

[0056] In one embodiment, such as Figure 1 As shown, the seat fixing platform 100 also includes a base pulley 105 and a lifting mechanism 106. The base pulley 105 is located at the bottom of the seat cushion platform 102 and is used to move and fix the seat fixing platform 100. The lifting mechanism 106 is located at the bottom of the seat cushion platform 102 and is used to adjust the height of the seat fixing platform 100.

[0057] The seat fixing platform 100 is provided with a base pulley 105 at its bottom. The base pulley 105 can move and fix the seat fixing platform 100. A lifting mechanism 106 is also provided between the seat fixing platform 100 and the base pulley 105. The lifting mechanism 106 can adjust the height of the seat fixing platform 100 so that the seat 200 on the seat fixing platform 100 is in the same posture as the seat in a real driving environment.

[0058] In this embodiment, by setting base pulleys and a lifting mechanism, the movement and height of the seat fixing platform can be adjusted so that the seat on the seat fixing platform has the same posture as the seat in a real driving environment, which is suitable for various types of seats.

[0059] In one embodiment, such as Figure 2 As shown, the backrest 201 is provided with multiple sets of first fixing units 203, each set of first fixing units 203 including several metal rings 2031; each first thread 301 passes through several metal rings 2031 of a set of first fixing units 203 to achieve contact between the first thread 301 and the backrest 201. The seat cushion 202 is provided with multiple sets of second fixing units 204, each set of second fixing units 204 including several metal rings 2031; each second thread 302 passes through several metal rings 2031 of a set of second fixing units 204 to achieve contact between the second thread 302 and the seat cushion 202.

[0060] The backrest 201 is provided with multiple sets of first fixing units 203. Each set of first fixing units 203 includes several metal rings 2031. Specifically, the position of the metal rings 2031 is related to the design shape of the backrest 201, and is usually located at the edge seam of the backrest 201. The metal rings 2031 in each set of first fixing units 203 are within a certain position range and are approximately in a straight line. Similarly, the metal rings 203 in each set of second fixing units 204 on the seat cushion 202 are located at the edge seam of the seat cushion 202, and the metal rings 2031 in each set of second fixing units 204 are within a certain position range and are approximately in a straight line.

[0061] In this embodiment, by setting multiple metal rings to fix the threads to the seat, it can be ensured that each thread is completely in contact with the seat surface, so that the measured height value is more accurate.

[0062] In one embodiment, the processor 500 is further configured to acquire a standard line corresponding to the driver's seat 200; the standard line is the center line of the human body when the driver is sitting in the seat 200; determine the height difference corresponding to each thread based on a first height value and a second height value; fit the shape change line of the seat 200 based on the height difference corresponding to each thread; and compare the shape change line with the standard line to evaluate the seat comfort.

[0063] When a driver sits in the seat, a contour line similar to the seat surface appears, representing the driver's body shape. However, in practice, external factors can affect this contour line, such as thick clothing. Therefore, the center line of the body is usually used as the standard line representing the body shape. The processor compares the seat's shape change line with this standard line to analyze the fit between the seat and different parts of the driver's body. If the driver fits perfectly in the seat, the shape change line should be exactly the same as the standard line, indicating high seat comfort. This allows for an evaluation of seat comfort. In practice, if the processor finds that the upper part of the shape change line does not match the standard line, it means the driver's head may not be in contact with the seat, indicating poor comfort. In this case, the shape of the seat back can be adjusted to improve seat comfort.

[0064] In this embodiment, the height difference corresponding to each thread is determined based on the first height value and the second height value, and the shape change line of the seat is obtained by fitting multiple height differences. The shape change line is compared with the center line of the human body when the driver sits in the seat, which can accurately analyze the degree of fit between the seat and various parts of the driver's body, and thus evaluate the comfort of the seat.

[0065] In one embodiment, such as Figure 3 As shown, a method for evaluating seat comfort is provided, which can be applied to... Figure 1 Taking the processor in the example, the following steps are included:

[0066] S302: Obtain the first height value of each weight above the ground when the driver is seated in front of the seat.

[0067] The first height value is obtained by measuring instrument, specifically a coordinate measuring machine (CMM). The working principle of the CMM is to place the part to be measured into the three-dimensional space it allows to measure, and to return the surface data of each workpiece based on the probe system. The CMM software system can calculate various geometric shapes and dimensions. Here, the height value of each weight from the ground is measured before the driver sits down. The measured height value is processed and obtained as the first height value of each weight from the ground before the driver sits down in the seat, which is the initial state of the weight.

[0068] S304: Obtain the second height value of each weight from the ground after the driver sits down in the seat.

[0069] The method for measuring the second height value is the same as the method for measuring the first height value. The height value of each weight from the ground after the driver sits in the seat is measured by a coordinate measuring machine. The processor obtains the measured height value as the second height value of each weight from the ground after the driver sits in the seat, which can also be understood as the final state of the weights.

[0070] The seat includes a backrest and a seat cushion. The seat cushion is parallel to the ground, so the weights at the ends of each second thread surrounding the seat cushion are perpendicular to the ground and can be directly measured. Each first thread surrounding the backrest passes around a fixed pulley, which guides the thread. Therefore, the weights at the ends of the first threads are also perpendicular to the ground. This allows the coordinate measuring machine to more intuitively measure the first and second height values ​​of each weight from the ground.

[0071] S306: Seat comfort is evaluated based on the first height value and the second height value.

[0072] The system uses multiple weights corresponding to the seat. For each weight, a first and second height value are measured, yielding a height difference. This height difference represents the shape change value of a corresponding position point on the seat. By combining these shape change values ​​and height differences for each weight, the processor can fit a shape change line to the seat. To assess seat comfort, the driver's center line is obtained as a standard line representing their posture. The processor compares the shape change line with this standard line to analyze the fit between the seat and different parts of the driver's body. If the driver is fully seated, the shape change line should perfectly align with the standard line, indicating high seat comfort. In practical applications, if the processor finds that the upper part of the shape change line doesn't match the standard line, it means the driver's head may not be fully seated, indicating poor comfort. In this case, the seat back shape can be adjusted to improve comfort.

[0073] In the above-mentioned seat comfort assessment method, the first height values ​​of each weight from the ground in front of the driver and the second height values ​​of each weight from the ground behind the driver are obtained. Based on the first and second height values, the shape change line of the seat is obtained. The shape change line is compared with the standard line corresponding to the driver behind the seat. This allows for an accurate analysis of the fit between the seat and various parts of the driver's body, thereby assessing the seat comfort.

[0074] In one embodiment, such as Figure 4 As shown, the steps for evaluating seat comfort based on the first height value and the second height value include:

[0075] S402: Determine the height difference corresponding to each thread based on the first height value and the second height value.

[0076] The first and second height values ​​are both measured by a measuring instrument. The processor determines the height difference corresponding to each thread based on the obtained first and second height values. Since there are multiple threads, there are also multiple height differences.

[0077] S404: The shape change line of the seat is obtained by fitting the height difference corresponding to each thread.

[0078] The seat has multiple weights. For each weight, the first and second height values ​​are measured. This allows us to obtain the height difference for each weight. This height difference actually represents the shape change value of the corresponding position point of the seat. By using the shape change values ​​of multiple position points, i.e., the corresponding height difference for each weight, the processor can fit the shape change line of the seat.

[0079] S406: Compare the shape change line with the standard line to assess seat comfort.

[0080] To assess seat comfort, it's necessary to obtain the driver's center line when seated, serving as a standard line representing the driver's posture. The processor compares the shape change line with this standard line to analyze the degree of fit between the seat and different parts of the driver's body. If the driver is fully fitted to the seat, the shape change line should perfectly align with the standard line, indicating high seat comfort. In practical applications, if the processor finds that the upper part of the shape change line doesn't match the standard line, it suggests the driver's head may not be fully fitted, indicating poor seat comfort. Therefore, the seat back shape can be adjusted to improve comfort.

[0081] In this embodiment, the height difference corresponding to each thread is determined based on the first height value and the second height value, and the shape change line of the seat is obtained by fitting the height difference corresponding to each thread. This can accurately analyze the degree of fit between the seat and various parts of the driver's body, and thus evaluate the seat comfort.

[0082] In one embodiment, such as Figure 5 As shown, a method for measuring the shape of a seat is provided, which includes the following steps:

[0083] Step 1: Secure the seat to the seat mounting bracket, adjust the height of the seat base to match the actual vehicle position, and adjust the tilt angle of the seat back to be parallel to the seat back.

[0084] Step 2: Measure the position of the seat hinge mechanism and mark its projection on the center line of the seat cushion and backrest. Along the center line, starting from this point, take a point every 50mm and extend it to the end of the seat cushion and backrest.

[0085] Step 3: Fix the wire to the cross section at the point taken in Step 2 with a miniature metal ring, and tie a small counterweight to the end of the wire to ensure that the wire is just taut and in contact with the seat surface. The counterweight on the seat cushion hangs naturally to the ground, and the wire on the backrest hangs naturally after passing over the fixed pulley on the fixed platform.

[0086] Step 4: When the driver is not seated, keep the thread in contact with the seat surface and use a coordinate measuring machine to measure the height of the weight block from the ground to obtain the first height value.

[0087] Step 5: After the driver sits down, use a coordinate measuring machine to measure the height of the weight block above the ground to obtain the second height value;

[0088] Step Six: The processor determines the height difference corresponding to each thread based on the first and second height values. It then fits the shape change line of the seat based on the height difference and compares the shape change line with the center line of the driver's body after sitting down to evaluate the seat comfort.

[0089] In this embodiment, the shape change line of the seat is obtained by measuring the height difference between the weights and the ground before and after the driver sits on the seat. The shape change line is then compared with the center line of the driver's body after sitting down to evaluate the degree of fit between the seat surface shape and the driver, thereby evaluating the seat comfort.
