[0049] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts fall within the scope of protection of the present invention.
[0050] In one embodiment, as Figure 1 and Figure 2 shown, a seat testing method applied to a seat testing system is provided, including:
[0051] S10. Obtain true human body pressure distribution data;
[0052] S20. Install the profiling tooling on the bump and creep test bench, and a body pressure distribution pad is placed between the profiling tooling and the bump and creep test bench;
[0053] S30. Adjust the profiling parameters of the profiling tooling so that the pressure distribution data collected through the body pressure distribution pad is consistent with the true human body pressure distribution data;
[0054] S40. Perform a bump and creep test on the profiling tooling according to specified test parameters to obtain seat test results.
[0055] It can be understood that the seat testing method provided in this embodiment can be applied to Figure 1The seat test system shown. The seat test system includes a bump and creep test bench 01, a profiling tooling 02, a counterweight 03, and a body pressure distribution pad 04. The bump and creep test bench 01 is provided with a test seat and provides vibration excitation. The profiling tooling 02 simulates the human hip structure and can replace a real person for seat testing. A plurality of pressure sensors are installed on the body pressure distribution pad 04, and can measure the pressure of different parts of the profiling tooling 02 during the bump and creep test. The counterweight 03 can be placed on the profiling tooling 02 to simulate real people of different weights.
[0056] The real human body pressure distribution data can refer to the body pressure distribution data collected through the body pressure distribution pad 04 after a real person of a specific body type adjusts the seat, etc. to a comfortable driving and sitting posture in a real vehicle.
[0057] In some examples, the real human body pressure distribution data includes body pressure-time data at multiple position points. In the body pressure-time data, the body pressure at the position points changes with time.
[0058] After obtaining the real human body pressure distribution data, the profiling tooling 02 can be installed on the bump and creep test bench 01. The body pressure distribution pad 04 is placed between the profiling tooling 02 and the bump and creep test bench 01.
[0059] Before performing the bump and creep test, it is necessary to adjust the profiling parameters of the profiling tooling 02 to approximate the profiling tooling 02 to a real person. Here, the profiling parameters refer to the counterweight and the tooling mass distribution parameters in the profiling tooling 02. Different configurations correspond to real people of different weights. The tooling mass distribution parameters include the tooling bone height, the tooling bone angle, and the tooling angle. By adjusting the tooling bone height, the tooling bone angle, and the tooling angle, the mass distribution of the profiling tooling 02 can be changed. Different mass distributions will generate different pressure distribution data. When the pressure distribution data generated by the profiling tooling 02 is consistent with the real human body pressure distribution data, it can be considered that the profiling tooling 02 is approximated to a real person. If the approximation degree of the pressure distribution data and the real human body pressure distribution data is high, or the difference between the pressure distribution data and the real human body pressure distribution data is less than a preset pressure threshold, it is determined that the pressure distribution data is consistent with the real human body pressure distribution data.
[0060] After determining that the pressure distribution data generated by the profiling tooling 02 is consistent with the real human body pressure distribution data, the profiling tooling 02 can be subjected to a bump and creep test according to specified test parameters to obtain a seat test result. Here, the specified test parameters include but are not limited to the bump frequency, the creep frequency, the creep direction, and the creep distance. In one example, the bump frequency can be carried out in accordance with "QC / T 740 Passenger Car Seat Assembly", the creep frequency is 4 times per minute, on the basis of the conventional bump and creep, the creep in the front and rear directions is increased, the creep frequency is 1 time per minute, and the creep distance is 10 mm forward.
[0061] This embodiment provides a profiling tooling that is closer to a real person, which can better simulate the durability of a real person's ride, and the seat test results obtained through the profiling tooling are more accurate.
[0062] Optionally, step S30, that is, adjusting the profiling parameters of the profiling tooling so that the pressure distribution data collected by the body pressure distribution pad is consistent with the real person's body pressure distribution data, includes:
[0063] S301. Measure the pressure distribution data of the profiling tooling under real person conditions; the real person conditions are the conditions corresponding to the real person's body pressure distribution data;
[0064] S302. Determine whether the difference between the pressure distribution data and the real person's body pressure distribution data is greater than a preset pressure threshold;
[0065] S303. If the difference between the pressure distribution data and the real person's body pressure distribution data is greater than or equal to the preset pressure threshold, reset the profiling parameters of the profiling tooling, and measure the pressure distribution data of the profiling tooling under real person conditions after resetting the profiling parameters;
[0066] S304. When the difference between the pressure distribution data and the real person's body pressure distribution data is less than the preset pressure threshold, it is determined that the pressure distribution data is consistent with the real person's body pressure distribution data.
[0067] It is understandable that when collecting the real person's body pressure distribution data, the corresponding conditions can be recorded, which are the real person conditions. Restore the real person conditions on the profiling tooling 02, and at the same time measure the corresponding pressure distribution data. Determine whether the difference between the pressure distribution data and the real person's body pressure distribution data is greater than the preset pressure threshold. If the difference between the pressure distribution data and the real person's body pressure distribution data is greater than or equal to the preset pressure threshold, reset the profiling parameters of the profiling tooling 02, and measure the pressure distribution data of the profiling tooling 02 under real person conditions after resetting the profiling parameters. The preset pressure threshold can be set according to actual needs, such as 10% of the real person's body pressure. The profiling parameters include but are not limited to counterweights and tooling mass distribution parameters. Among them, the tooling mass distribution parameters refer to the parameters that affect the mass distribution of the profiling tooling 02, such as the tooling bone height, tooling bone angle, and tooling angle.
[0068] When the difference between the pressure distribution data and the real person's body pressure distribution data is less than the preset pressure threshold, it is determined that the profiling parameters are consistent with the real person's body pressure distribution data.
[0069] This embodiment adjusts the profiling parameters to make the pressure exerted by the profiling tooling on the seat closer to the pressure generated by a real person's ride.
[0070] Optionally, the real person's body pressure distribution data includes body pressure-time data at multiple position points.
[0071] Understandably, the body pressure distribution pad 04 is provided with a plurality of pressure sensors. Each pressure sensor can measure the body pressure-time data at a position point. When a real person sits on the vehicle seat, the pressure exerted on the seat will change to a certain extent. The body pressure-time data can reflect the pressure change at the position point. By adjusting the profiling parameters of the profiling tooling 02 to make the pressure distribution data match the real body pressure distribution data, the durability of real-person riding can be better simulated, and the seat test results obtained through the profiling tooling 02 are more accurate.
[0072] Optionally, the profiling parameters include the counterweight and the tooling mass distribution parameters.
[0073] Understandably, the profiling parameters include the counterweight and the tooling mass distribution parameters. The counterweight can be adjusted by the counterweight block 03. The profiling tooling 02 includes a plurality of adjustable components to realize the adjustment of the tooling mass distribution parameters.
[0074] Optionally, the tooling mass distribution parameters include the tooling bone height, the tooling bone angle, and the tooling angle.
[0075] Understandably, the profiling tooling 02 is provided with a vertical adjustment mechanism 022 for the bone simulation block, a bone angle adjustment mechanism 023, and a tooling angle adjustment mechanism 027. Among them, the vertical adjustment mechanism 022 for the bone simulation block is used to adjust the tooling bone height; the bone angle adjustment mechanism 023 is used to adjust the tooling bone angle; the tooling angle adjustment mechanism 027 is used to adjust the tooling angle.
[0076] Optionally, before step S40, before performing the bump and creep test on the profiling tooling according to the specified test parameters and obtaining the seat test results, it further includes:
[0077] S31. Obtain the seat parameters associated with the real body pressure distribution data;
[0078] S32. Set the test seat on the bump and creep test bench according to the seat parameters.
[0079] Understandably, when collecting the real body pressure distribution data, the adjustment position and angle of the corresponding seat can be recorded, which are the seat parameters associated with the real body pressure distribution data.
[0080] When performing the bump and creep test, adjust the seat parameters of the test seat to be the same as those of the real person sitting on the seat to obtain more accurate seat test results.
[0081] In this embodiment, by adjusting the seat parameters of the test seat, the durability of real-person riding can be better simulated.
[0082] It should be understood that the sequence numbers of the steps in the above embodiments do not indicate the order of execution. The order of execution of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiments of the present invention.
[0083] In one embodiment, as Figure 1 shown, a seat testing system is provided, including a bump and creep test bench 01, a profiling tooling 02, and a body pressure distribution pad 04;
[0084] The bump and creep test bench 01 is provided with a test seat;
[0085] The profiling tooling 02 is placed on the test seat;
[0086] The body pressure distribution pad 04 is placed between the test seat and the test seat position;
[0087] Before performing the bump and creep test, obtain the real human body pressure distribution data; install the profiling tooling 02 on the bump and creep test bench 01, and adjust the profiling parameters of the profiling tooling 02 so that the pressure distribution data collected through the body pressure distribution pad 04 is consistent with the real human body pressure distribution data;
[0088] When performing the bump and creep test, the bump and creep test bench 01 causes the test seat to undergo bump and creep according to the specified test parameters, and obtains the seat test result.
[0089] It can be understood that the seat testing system provided in this embodiment includes a bump and creep test bench 01, a profiling tooling 02, a counterweight 03, and a body pressure distribution pad 04. The bump and creep test bench 01 is provided with a test seat and provides vibration excitation. The profiling tooling 02 simulates the human hip structure and can replace a real person for seat testing. A plurality of pressure sensors are installed on the body pressure distribution pad 04, and the pressure of different parts of the profiling tooling 02 can be measured during the bump and creep test. The counterweight 03 can be placed on the profiling tooling 02 to simulate real people with different weights.
[0090] The real human body pressure distribution data can refer to the body pressure distribution data collected through the body pressure distribution pad 04 after a real person with a specific body type adjusts the seat, etc. to a comfortable driving and riding posture in a real vehicle.
[0091] In some examples, the real human body pressure distribution data includes body pressure-time data at multiple position points. In the body pressure-time data, the body pressure at the position point changes with time.
[0092] After obtaining the real human body pressure distribution data, the profiling tooling 02 can be installed on the bump and creep test bench 01. A body pressure distribution pad 04 is placed between the profiling tooling 02 and the bump and creep test bench 01.
[0093] Before conducting the bump and creep test, it is necessary to adjust the profiling parameters of the profiling tooling 02 to make the profiling tooling 02 approximate to a real person. Here, the profiling parameters refer to the counterweight and the tooling mass distribution parameters in the profiling tooling 02. Different configurations correspond to real people of different weights. The tooling mass distribution parameters include the tooling bone height, the tooling bone angle, and the tooling angle. By adjusting the tooling bone height, the tooling bone angle, and the tooling angle, the mass distribution of the profiling tooling 02 can be changed. Different mass distributions will generate different pressure distribution data. When the pressure distribution data generated by the profiling tooling 02 is consistent with the real body pressure distribution data, it can be considered that the profiling tooling 02 is approximate to a real person. If the approximation degree of the pressure distribution data to the real body pressure distribution data is high, or the difference between the pressure distribution data and the real body pressure distribution data is less than the preset pressure threshold, it is determined that the pressure distribution data is consistent with the real body pressure distribution data.
[0094] After determining that the pressure distribution data generated by the profiling tooling 02 is consistent with the real body pressure distribution data, the bump and creep test can be carried out on the profiling tooling 02 according to the specified test parameters to obtain the seat test results. Here, the specified test parameters include but are not limited to the bump frequency, the creep frequency, the creep direction, and the creep distance. In one example, the bump frequency can be carried out in accordance with "QC / T 740 Passenger Car Seat Assembly", the creep frequency is 4 times per minute, on the basis of the conventional bump and creep, the creep in the front and back directions is increased, the creep frequency is 1 time per minute, and the creep distance is 10 mm forward.
[0095] This embodiment provides a profiling tooling that is more approximate to a real person, which can better simulate the durability of a real person's ride, and the seat test results obtained through the test of this profiling tooling are more accurate.
[0096] Optionally, as Figure 3 shown, the bump and creep test bench 01 includes a vibration test bench 011, a tooling fixing rod 012, and a tooling adjusting mechanism 013;
[0097] The vibration test bench 011 is used to fix the test seat and provide vibration excitation;
[0098] The tooling fixing rod 012 is used to fix the profiling tooling 02;
[0099] The tooling adjusting mechanism 013 is used to adjust the installation position of the profiling tooling 02.
[0100] Understandably, the bump and creep test bench 01 includes three parts: a vibration test bench 011, a tooling fixing rod 012, and a tooling adjustment mechanism 013. The vibration test bench 011 is usually used to simulate the vibration environment during vehicle driving to test the performance and durability of the seat under vibration conditions. By fixing the seat on the vibration test bench 011 and providing specific vibration excitation, the vibration absorption ability, structural stability, and comfort of the seat can be evaluated. During the vibration test, the vibration conditions under different road conditions can be simulated by adjusting the frequency, amplitude, and direction of the vibration table, such as driving on a flat road surface, a bumpy road surface, or lateral acceleration during a sharp turn. By conducting vibration tests on the seat, the performance of the seat structure, the reliability of the fixing system, the effect of the cushioning material, and the overall comfort of the seat can be evaluated. These tests help ensure that the automotive seat has good vibration comfort and durability during actual use and also help optimize the seat design and manufacturing process.
[0101] The tooling fixing rod 012 is a tool for fixing the profiling tooling 02 to prevent the profiling tooling 02 from shifting in position during the bump and creep test. The tooling adjustment mechanism 013 is used to adjust the installation position of the profiling tooling 02. The installation position of the profiling tooling 02 can be adjusted according to the sitting posture of a real person.
[0102] This embodiment provides three components of the bump and creep test bench 01, and all three components play important roles in the bump and creep test.

This mechanism enables the profiling tooling 02 to be tested at different angles, thus meeting different test requirements.
[0107] The front-back movement adjustment mechanism can include components such as guide rails, sliders, and screws. Through the coordinated movement of these components, the front-back position of the profiling tooling 02 in the horizontal direction can be adjusted. This mechanism enables the profiling tooling 02 to be adjusted in the front-back position according to the sitting position of a real person to meet the test requirements in different scenarios.
[0108] Optionally, as Figure 4As shown in the figure, the profiling tooling 02 includes a first fixing block 021, a second fixing block 026, a bone simulation block 024, an up-and-down adjustment mechanism 022 for the bone simulation block, an angle adjustment mechanism 023 for the bone, a false buttock simulation block 025, and an angle adjustment mechanism 027 for the tooling.
[0109] The up-and-down adjustment mechanism 022 for the bone simulation block is fixed on the false buttock simulation block 025 through the first fixing block 021; the up-and-down adjustment mechanism 022 for the bone simulation block is connected to the first fixing block 021 through a first connecting member; the first fixing block 021 and the false buttock simulation block 025 are connected through a second connecting member.
[0110] The bone simulation block 024 is fixed on the up-and-down adjustment mechanism 022 for the bone simulation block through the angle adjustment mechanism 023 for the bone; the bone simulation block 024 is connected to the angle adjustment mechanism 023 for the bone through a third connecting member; the angle adjustment mechanism 023 for the bone and the up-and-down adjustment mechanism 022 for the bone simulation block are connected through a fourth connecting member.
[0111] The angle adjustment mechanism 027 for the tooling and the second fixing block 026 are fixed on the false buttock simulation block 025 through a fifth connecting member.
[0112] Understandably, the profiling tooling 02 includes a first fixing block 021, a second fixing block 026, a bone simulation block 024, an up-and-down adjustment mechanism 022 for the bone simulation block, an angle adjustment mechanism 023 for the bone, a false buttock simulation block 025, and an angle adjustment mechanism 027 for the tooling. Among them, the up-and-down adjustment mechanism 022 for the bone simulation block is fixed on the false buttock simulation block 025 through the first fixing block 021; the bone simulation block 024 is connected to the first fixing block 021 through a first connecting member; the first fixing block 021 and the false buttock simulation block 025 are connected through a second connecting member. The bone simulation block 024 is fixed on the up-and-down adjustment mechanism 022 for the bone simulation block through the angle adjustment mechanism 023 for the bone; the bone simulation block 024 is connected to the angle adjustment mechanism 023 for the bone through a third connecting member; the angle adjustment mechanism 023 for the bone and the up-and-down adjustment mechanism 022 for the bone simulation block are connected through a fourth connecting member. The angle adjustment mechanism 027 for the tooling and the second fixing block 026 are fixed on the false buttock simulation block 025 through a fifth connecting member. The first connecting member, the second connecting member, the third connecting member, the fourth connecting member, and the fifth connecting member can be selected according to actual needs, such as bolts, buckles, etc.
[0113] The profiling tooling 02 provided in this embodiment includes three adjustment mechanisms: the up-and-down adjustment mechanism 022 for the bone simulation block, the angle adjustment mechanism 023 for the bone, and the up-and-down adjustment mechanism 022 for the bone simulation block, which can respectively adjust the height of the tooling bone, the angle of the tooling bone, and the angle of the tooling.
[0114] Optionally, the up-and-down adjustment mechanism 022 of the bone simulation block is provided with a first chute; the first chute is used to adjust the height of the tooling bone of the bone simulation block 024;
[0115] The bone angle adjustment mechanism 023 is used to adjust the tooling bone angle of the bone simulation block 024;
[0116] The tooling angle adjustment mechanism 027 is provided with a second chute; the second chute is arc-shaped and is used to adjust the tooling angle of the false hip simulation block 025.
[0117] Understandably, the up-and-down adjustment mechanism 022 of the bone simulation block is provided with a first chute in the vertical direction. The up-and-down adjustment mechanism 022 of the bone simulation block is fixed on the first fixing block 021 through the first chute. The up-and-down adjustment mechanism 022 of the bone simulation block can change its own height due to different fixed positions on the first chute. Since the bone simulation block 024 is installed on the up-and-down adjustment mechanism 022 of the bone simulation block through the bone angle adjustment mechanism 023, when the height of the up-and-down adjustment mechanism 022 of the bone simulation block changes, the height of the tooling bone of the bone simulation block 024 also changes accordingly.
[0118] The bone angle adjustment mechanism 023 is used to adjust the tooling bone angle of the bone simulation block 024. The tooling bone angle can change the left-right orientation of the profiling tooling 02.
[0119] The tooling angle adjustment mechanism 027 is provided with a second chute; the second chute is arc-shaped and is used to adjust the tooling angle of the false hip simulation block 025. Here, the tooling angle can refer to the up-and-down orientation of the profiling tooling 02.
[0120] Optionally, a counterweight block 03 is further included; the profiling parameters include counterweight;
[0121] The counterweight block 03 is used to adjust the counterweight of the profiling tooling 02.
[0122] Understandably, the counterweight block 03 is an important component for adjusting the balance and stability of the profiling tooling 02. By increasing or decreasing the weight of the counterweight block 03, the counterweight of the profiling tooling 02 can be adjusted, so as to ensure that the profiling tooling 02 generates the same or similar pressure on the test seat during use as a real person.
