Description

Technical Field

[0001] This utility model belongs to the field of testing tooling technology, and in particular relates to a force testing tooling for a car driving simulator pedal. Background Technology

[0002] With the development of automotive intelligence and driving simulation technology, driving simulators are playing an increasingly prominent role in vehicle research and development, driver training, and human-machine interface (HMI) verification. As the core control components of the simulator, the mechanical feedback characteristics of the accelerator pedal, brake pedal, and clutch pedal (such as linearity of force, rebound response, and hysteresis) directly affect the realism of simulated driving and the reliability of test data.

[0003] Currently, the force performance testing of car driving simulator pedals mainly relies on real vehicle testing methods. This method involves installing the pedal in a real vehicle and testing it by having the driver step on it or by applying force through a mechanical device. This method has the following drawbacks: it is costly, has a long testing cycle, and cannot eliminate interference from other vehicle systems (such as hydraulic / electronic power steering systems), making it difficult for the test data to accurately reflect the mechanical performance of the pedal itself.

[0022] The following drawings will disclose several embodiments of this utility model. For clarity, many physical details will be described in the following description. However, it should be understood that these physical details should not be used to limit this utility model. That is, in some embodiments of this utility model, these physical details are not essential. In addition, for the sake of simplicity, some conventional structures and components will be shown in the drawings in a simple schematic manner.

[0023] Furthermore, in this utility model, the use of terms such as "first" and "second" is for descriptive purposes only and does not specifically refer to any order or sequence, nor is it intended to limit the utility model. They are merely used to distinguish components or operations described with the same technical terms and should not be construed as indicating or implying their relative importance or implicitly specifying the number of indicated technical features. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the technical solutions of various embodiments can be combined with each other, but only if they are feasible for those skilled in the art. If a combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.

[0024] This embodiment provides a force testing fixture for a car driving simulator pedal. The fixture has a simple structure and can perform force testing on the pedal by simulating the pedal with a simulation component. It eliminates the need for actual vehicle force testing, saving costs and reducing the testing cycle of the pedal force. It can also effectively eliminate interference from other vehicle systems and ensure the accuracy of the pedal force test.

[0025] Combination Figures 1 to 4 As shown, the force testing fixture for the pedal of the car driving simulator in this embodiment includes a base platform 10, a pedal simulation component 20, and a pressure head 30. A bracket 11 is provided on the base platform 10, and the pedal simulation component 20 is installed on the bracket 11. The pressure head 30 presses down on the pedal simulation component 20 to achieve the force test of the pedal.

[0026] In this embodiment, the bracket 11 includes a fixed column 111 and an inclined block 112. The fixed column 111 is installed on the base platform 10, and the bottom of the inclined block 112 is located on the base platform 10 and is inclined relative to the base platform 10. The top of the inclined block 112 is connected to the top of the fixed column 111 through the mounting plate 40. In this embodiment, the fixed column 111 supports and installs the inclined block 112. The base platform 10 is provided with a plurality of limiting sliders 60. The limiting sliders 60 contact the bottom of the inclined block 112 to limit the inclined block 112. The fixed column 111 installs the top of the inclined block 112, and the limiting sliders 60 limit the bottom of the inclined block 112 to achieve the inclined block 112 being installed at an inclination relative to the base platform 10. With the cooperation of the fixed column 111 and the limiting sliders 60, the inclined block 112 is stably installed so that the pedal simulation component 20 can be simulated and tested later.

[0027] Furthermore, the inclined block 112 in this embodiment is provided with a mounting groove 50 to change the position of the mounting plate 40. The mounting groove 50 is a linear groove. By changing the position of the mounting plate 40 and the limiting slider 60, the tilt angle of the inclined block 112 is adjusted to further meet the testing requirements of the pedal simulation component 20.

[0028] Combination Figure 1 , Figure 3 as well as Figure 4 As shown, the pedal simulation component 20 of this embodiment includes a base block 21 and a pressure block 22. The base block 21 is adjustablely mounted on the inclined block 112. The pressure block 22 is hinged to the base block 21. When the pressure block 22 is subjected to force, the pressure block 22 deforms relative to the base block 21. The pressure head 30 is connected to an external material testing machine to press down on the pressure block 22. After the pedal simulation component 20 is installed, the external material testing machine drives the pressure head 30 to press down on the pressure block 22. Based on the feedback data from the external material testing machine, the stress condition of the pressure block 22 is determined so as to complete the stress test of the pressure block 22 and complete the simulated stress test of the pedal.

[0029] In this embodiment, the inclined block 112 is provided with several limiting grooves 70 to limit the installation of the bottom block 21. The limiting grooves 70 are linear grooves. The end of the pressure block 22 is hinged to the center position of the bottom block 21. In this embodiment, the bottom block 21 is installed through the limiting grooves 70, and the position of the bottom block 21 can be adjusted to meet the force test requirements of the pedal. The end of the pressure block 22 is hinged to the center position of the bottom block 21. When the pressure head 30 presses down on the pressure block 22, the pressure block 22 will move relative to the bottom block 21 to simulate the force test of the pedal.

[0030] Furthermore, in this embodiment, the pressure head 30 is a spindle-shaped structure, and the base platform 10 is provided with several feet 80 at the bottom to support and install the base platform 10.

[0031] In this embodiment, the force testing fixture for the car driving simulator pedal uses a pedal simulator 20 instead of a pedal for force testing. An external material testing machine drives the pressure head 30 to press down on the pressure block 22. Based on the feedback data from the external material testing machine, the force condition of the pressure block 22 is determined to complete the force test of the pressure block 22, thereby completing the simulated force test of the pedal.
