At the same time, in accordance with the principles of improving the utilization of interior space and meeting the requirements of exterior styling and overall vehicle size, human-centered optimization design is carried out.

[0003] By studying the relationship between human body size and car interior space, and the comfortable human sitting posture of similar models, and taking into account the space of the designed model, the designed human sitting posture is derived, and its comfort level can be evaluated based on the reference model.

[0026] According to an embodiment of this application, a verification device is provided, which will be described below in conjunction with... Figure 1 and Figure 2 It describes the structure and working principle of the verification device.

[0027] According to the verification device provided in the embodiments of this application, the verification device includes a test platform 10, a vehicle frame mechanism, and a seat mechanism. In the embodiments, the vehicle frame mechanism is disposed on the test platform 10, and the seat mechanism is disposed on the test platform 10 and located within the space defined by the vehicle frame mechanism.

[0028] In one embodiment, at least a portion of the structure in the seat mechanism is movable relative to the test platform 10 to adjust the position of the seat mechanism relative to the test platform 10; at least a portion of the structure in the body frame mechanism is movable relative to the test platform 10 to adjust the position of the aforementioned at least a portion of the structure in the body frame mechanism relative to the test platform 10.

[0029] Thus, the verification device provided in this application embodiment can be used during the vehicle design phase to adjust the position of the seat mechanism relative to the test platform 10, facilitating the determination of a position where the seat mechanism can provide reasonable human-machine comfort, thereby determining the position of the seat mechanism suitable for human sitting posture, which can be used as a reference for vehicle design. The verification device provided in this application embodiment also incorporates an adjustable design for certain structures of the vehicle body frame mechanism relative to the test platform 10. By combining the adjustment of the seat mechanism's position with an emphasis on the design of the relative positional relationship between the seat position and the vehicle body frame structure itself, more scientific human-machine comfort results can be obtained.

[0030] According to the verification device provided in the embodiments of this application, the vehicle seat mechanism may include a driver's seat assembly and a passenger seat assembly, and the positions of the driver's seat assembly and the passenger seat assembly relative to the test platform 10 are adjustable.

[0031] Here, the driver's seat assembly and the passenger seat assembly can be set with reference to the driver's seat and passenger seat in the vehicle, respectively.

[0032] According to the verification device provided in the embodiments of this application, the seat mechanism may further include a first adjustment component, which may connect the driver's seat component and the test platform 10, and may drive the driver's seat component to move in the horizontal plane.

[0033] In an embodiment, the first adjustment component may include a drive combination structure formed by two sets of motors, lead screws and nuts. One set of motors, lead screws and nuts may be set along a first horizontal direction, such as the width direction of the test platform 10, corresponding to the width direction of the vehicle. The other set of motors, lead screws and nuts may be set along a second horizontal direction, such as the length direction of the test platform 10, corresponding to the length direction of the vehicle.

[0034] In this embodiment, the first adjustment component may further include a plate. The first set of motors is directly connected to the lead screw. A nut may be fitted on the lead screw. The nut may be connected to the plate. The plate may be slidably connected to the mounting plane where the motors and lead screws are located (which may be the upper side of the test platform 10 or other plates) through a slider and a guide rail. A second set of motors, lead screws and nuts may be placed on the plate. Then, plates may be stacked on top of this set of motors, lead screws and nuts (sliders and guide rails may also be set between this plate and the plates below). The upper side of the uppermost plate may be used to set the main driving component.

[0035] According to the verification device provided in the embodiments of this application, the seat mechanism may further include a second adjustment component, which connects the passenger seat component to the test platform 10 and drives the passenger seat component to move in the horizontal plane.

[0036] Here, the second adjustment component can have the same structure as the first adjustment component, and therefore have the same setting method and working principle, which will not be described again here.

[0037] As described above, in the verification device provided according to the embodiments of this application, the positions of the driver's seat assembly and the passenger seat assembly relative to the test platform 10 in the horizontal plane are adjusted independently, that is, the positions of the driver's seat assembly and the passenger seat assembly relative to the test platform 10 in the horizontal plane are adjusted independently by using the first adjustment assembly and the second adjustment assembly without interfering with each other.

[0038] According to the verification device provided in the embodiments of this application, the driver's seat assembly and the passenger seat assembly are adjusted synchronously in height relative to the test platform 10. That is to say, a larger plate can be set below the first adjustment assembly and the second adjustment assembly and above the test platform 10. A height adjustment assembly 20 can be set at the bottom of the plate, which is essentially a lifting structure, so as to raise or lower the driver's seat assembly and the passenger seat assembly above the first adjustment assembly, the second adjustment assembly, and the two adjustment assemblies as a whole.

[0039] According to the verification device provided in this application embodiment, the vehicle body frame mechanism may include an A-pillar assembly 30 and a B-pillar assembly 40. The position of the A-pillar assembly 30 relative to the test platform 10 can be adjusted in the width direction of the test platform 10, and the position of the B-pillar assembly 40 relative to the test platform 10 can be adjusted in the length direction of the test platform 10, with the length direction perpendicular to the width direction. Here, the A-pillar assembly 30 and B-pillar assembly 40 of the vehicle body frame mechanism are designed to be adjustable relative to the test platform 10. This, combined with the adjustment of the seat mechanism's position, focuses on the design of the relative positional relationship between the seat position and the vehicle body frame structure itself, which is conducive to obtaining more scientific human-machine comfort results and realizing the test approach that combines comfort and blind spot verification.

[0040] According to the verification device provided in this application embodiment, the verification device includes a pedal mechanism 50 and a third adjustment component. The third adjustment component connects the test platform 10 and the pedal mechanism 50, and drives the pedal mechanism 50 to perform three-coordinate motion. Here, the third adjustment component can be set according to the first and second adjustment components as described above, and a lifting component can be added at the bottom. The lifting component can refer to a lifting structure. It should also be noted that handwheels can be added to the ends of the three sets of lead screws in the third adjustment component to manually adjust the position of the pedal mechanism 50. Here, the three-coordinate motion refers to the movement in the width direction, length direction, and height direction.

[0041] According to the verification device provided in the embodiments of this application, the pedal mechanism 50 includes a brake pedal and an accelerator pedal, which are arranged side by side. The distance between the brake pedal and the accelerator pedal can be adjusted. For example, a plate can be provided below the brake pedal and the accelerator pedal, and an oblong hole extending along the width direction can be provided on the plate. One of the brake pedal and the accelerator pedal is connected to the oblong hole using bolts and nuts. By loosening the nut, the distance between the brake pedal and the accelerator pedal relative to the other in the width direction can be adjusted.

[0042] According to the verification device provided in the embodiments of this application, the verification device includes a steering mechanism 60 (i.e., a steering wheel assembly) and a fourth adjustment component. The fourth adjustment component connects the test platform 10 and the steering mechanism 60, and drives the steering mechanism 60 to perform three-axis motion. Here, the setting method of the fourth adjustment component is the same as that of the third adjustment component, and will not be described again. The setting and adjustability of the steering mechanism 60 are beneficial for obtaining more accurate human-machine comfort test results.

[0043] Based on the technical solutions described above, the following is a brief description of more specific implementation methods.

[0044] The driver and passenger seats are electrically adjustable, supporting six directions: fore-aft, left-right, and up-down. The lifting mechanism adjusts the driver and passenger seats up-down simultaneously, while the fore-aft, left-right, and right-down directions can be adjusted independently. The lifting mechanism uses four existing lifters arranged in a U-shape. Each lifter, for example, has a load capacity of 100KG and a servo motor power greater than 0.55KW. Fore-aft, left-right, and right-down adjustments are made using electric lead screws with an effective travel of 400mm and a servo motor power of 200W.

[0045] The pedal mechanism 50 is adjustable in six directions. The distance between the brake pedal and the accelerator pedal can also be adjusted left and right using an adjusting bolt. The steering column position of the steering mechanism 60 can be adjusted in six directions: forward and backward, left and right, and up and down, and is composed of three hand-cranked screws.

[0046] For the seatbelt mechanism 70, one hand crank is used for height adjustment at each of the driver's and passenger's seatbelt anchor points, and four hand cranks are used for position adjustment at four locations: A-pillar and B-pillar. The A-pillar can be adjusted in two directions (left and right), and the B-pillar can be adjusted in four directions (front, back, left, and right).

[0047] The verification device provided in the embodiments of this application also includes a control system 80, namely a human-machine interface (HMI) test bench system. Human posture parameters, pedal parameters, steering parameters, and seatbelt parameters from the design phase are input into the HMI test bench system. The seat mechanism, pedal mechanism 50, steering mechanism 60, and seatbelt mechanism 70 are automatically or manually adjusted to their corresponding positions based on the input HMI parameters. Test personnel experience driving comfort on the HMI test bench. If any aspects are unsatisfactory, the positions of each mechanism can be adjusted based on the actual experience, parameters are collected, and the results are output back to the designers.

[0048] The advantage of the verification device provided in the embodiments of this application is that, during the design phase, pre-designed human-machine parameters can be imported into the human-machine test bench, and fine-tuned through the motion mechanism on the test bench to find a driving posture that suits most people, thereby providing reverse guidance for the design, avoiding risks in advance, and reducing development costs.

[0049] The above are merely preferred embodiments of this application and do not limit the scope of protection of this application. Any equivalent structural transformations made based on the innovative concept of this application and the contents of the specification and drawings of this application, or direct / indirect applications in other related technical fields, are included within the scope of protection of this application.
