Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments.

If the specific posture changes, the directional indications will also change accordingly.
[0032] In addition, if there are descriptions involving "first", "second", etc. in the embodiments of the present utility model, the descriptions of "first", "second", etc. are only for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the quantity of the indicated technical features.

When the combination of technical solutions results in contradictions or cannot be implemented, it should be considered that such a combination of technical solutions does not exist and is not within the protection scope required by the present utility model.
[0033] In the prior art, sensors are usually provided on the pedal. The rotation angle and torque of the pedal are detected by the sensors and then fed back to vehicle auxiliary control and game control, so as to bring a real vehicle control experience to the user. Among them, the pedal needs to rotate at an angle and the torque during the rotation process should meet the preset requirements to provide a good experience for the user. Existing detections usually only detect the torque and then compare the torque with the rotation angle to obtain the torque distribution structure during the rotation process. However, this later combination method is prone to large errors. For example, during a certain period of time, the torque is balanced or fluctuates, while the rotation angle is evenly distributed. At this time, if the torque is still paired with the rotation angle evenly, a situation where a certain rotation angle does not correspond to the torque will occur, resulting in a large test error. In addition, the later combination and comparison method also increases the detection difficulty.
[0034] The utility model provides a detection device based on a sensor.
[0035] In an embodiment of the utility model, please refer to Figures 1 to 4 , the test device based on the sensor is used to test the pedal 300. The pedal 300 is provided with a sensor. The test device based on the sensor includes:
[0036] A base 100, on the upper part of the base 100, there is a test position 110 and a driving member 120. The test position 110 is used for the pedal 300 to be placed in a limited position;
[0037] A rotating pressing member 200, which is rotatably arranged on the base 100 and is in transmission connection with the driving member 120. The rotating pressing member 200 is used to press the pedal 300;
[0038] A calibration sensor 150, which is arranged at the rotation connection of the rotating pressing member 200 and the base 100. The calibration sensor 150 is used to detect the rotation torque and rotation angle of the pedal 300; and
[0039] A control module, which is electrically connected to the driving member 120 and the calibration sensor 150, is used to compare the detection values of the calibration sensor 150 and the sensor, and control the operating state of the driving member 120.
[0040] The technical solution of the present utility model is to set a test position 110 on the base 100, and place the pedal 300 in a limited position at the test position 110. Then, a rotating pressing member 200 controlled to rotate by a driving member 120 is provided on the base 100, so that the rotating pressing member 200 can rotate towards the pedal 300 and press the pedal 300 to rotate. Among them, a calibration sensor 150 is provided at the rotating connection of the pressing member and the base 100 to detect the torque transmitted to the rotating pressing member 200 during the process of the pedal 300 being pressed down, and synchronously detect the rotation angle of the pedal 300. During the process of the driving member 120 driving the rotating pressing member 200 to rotate, the calibration sensor 150 can obtain detection values such as the rotation angle of the pedal 300 and the torque during the rotation of the pressing member, and transmit the detection values to the control module. The control module then compares the detection values obtained by the calibration sensor 150 with the detection values of the sensor on the pedal 300 to realize the test of the pedal 300, and thus facilitate subsequent adjustment. In this way, the rotation angle of the pedal 300, the torque generated by the rotation of the pedal 300 can be completed with a single operation, and the real-time torque of the pedal 300 at each rotation angle can be accurately reflected, and these detection values are compared with those obtained by the sensor on the pedal 300 to achieve the purpose of detection and calibration, thereby reducing the detection error and improving the convenience of detection.
[0041] Among them, when the control module obtains the detection values of the calibration sensor 150, including parameters such as the torque and rotation angle of the pedal 300, it will synchronously display the numerical relationship between the torque and the rotation angle on the display screen of the base 100. During this process, the torque and rotation angle of the pedal 300 will be detected under different output powers of the driving member 120. Specifically, the driving member 120 is configured as a motor. Of course, in some cases, the driving member 120 and the test driving member 120 can also be cylinders or oil cylinders, etc.
[0042] It should be noted that the calibration sensor 150 can integrate the torque and angle detection functions, or can be a separate torque sensor and angle sensor. The torque sensor and the angle sensor can both be arranged at the rotation connection between the pressing and rotating member and the base 100. Alternatively, the torque sensor is arranged at the rotation connection between the pressing and rotating member and the base 100, and the angle sensor is arranged on the relative member between the steering wheel and the test workpiece. It can be understood that the pedal 300 is at least circumferentially limited and fixed at the test position 110, and the test position 110 remains stable on the base 100, so as to prevent the pedal 300 from moving or rotating during the test, resulting in a large error in torque measurement. In addition, the pedal 300 mentioned in this solution refers to a pedal including a support seat installed at the test position 110 and a stepping part rotatably connected to the support seat. When the stepping part is stepped on by an external force, it will receive a reverse torque, and this part of the torque needs to be adapted to the rotation angle of the stepping part, so as to obtain an actual driving experience for the user when stepping on the stepping part. This can be used in the assisted driving of automobiles or in the driving games of automobile simulation. In this solution, the pressing and rotating member presses the stepping part of the above-mentioned pedal 300.
[0043] In one embodiment, please refer to Figure 1 and Figure 3 , the rotating pressing member 200 includes a rotating arm 210 and a push rod 220. The rotating arm 210 is rotatably connected to the base 100, and the push rod 220 is arranged on the rotating arm 210 and is used to press the pedal 300. It can be understood that the rotating arm 210 is connected to the base 100 in a rotatable connection manner, providing a stable support platform for the push rod 220 and serving as an intermediate link for power transmission to transmit the power generated by the driving member 120 to the push rod 220. Thus, the pressing and rotating member can rotate smoothly and steadily during the test, so as to accurately simulate the user's foot movement. In addition, by adjusting the connection angle between the rotating arm 210 and the base 100, the pressing angle of the push rod 220 can be adjusted, so that the test device can simulate the operation of the pedal 300 at different angles and meet different test requirements. The arrangement of the push rod 220 provides a layout space for the relative positions of the rotating arm 210 and the pedal 300, improving the specification range of the pedal 300 that can be tested and the applicability of the test device. Of course, in other embodiments, the rotating arm 210 can also directly rotate and press on the pedal 300.
[0044] Furthermore, in this embodiment, please refer to Figures 1 to 3In the extension direction of the rotating arm 210, the push rod 220 is movably connected to the rotating arm 210. In this way, the push rod 220 can adjust its angle and position relative to the rotating arm 210 as needed to adapt to pedals 300 of different specifications, thereby improving the flexibility and adaptability of the test. Among them, by adjusting the angle and position of the push rod 220, the test device can more accurately simulate the operation of the pedal 300 in a real driving scene. Specifically, the push rod 220 can be adjusted to a position perpendicular to or parallel to the pedal 300. Of course, in other embodiments, the push rod 220 and the rotating arm 210 can also be fixedly connected.
[0045] In one embodiment, please refer to Figures 1 to 3 The rotating pressing member 200 includes two rotating arms 210, and the two ends of the push rod 220 are respectively connected to the two rotating arms 210. The two ends of the push rod 220 are respectively connected to the two rotating arms 210, forming a double-point support structure. Compared with the single-point support, this support is more stable and can effectively reduce the shaking and deviation of the push rod 220 during the pressing process, ensuring the accuracy and consistency of the pressing action. Similarly, the design of the double rotating arms 210 enhances the rigidity of the entire rotating pressing member 200. During the pressing process, the two rotating arms 210 can jointly bear the force transmitted by the push rod 220, reduce the deformation or damage caused by the concentration of force, and improve the durability and reliability of the test device. Without loss of generality, for the drive of the two rotating arms 210, a driving member 120 can be set to drive the two rotating arms 210 to rotate synchronously through the transmission structure, or two driving members 120 are respectively set to drive the corresponding rotating arms 210 to rotate. Of course, in other embodiments, only one rotating arm 210 may be provided to pull the push rod 220 to rotate so as to press the pedal 300 .
[0046] In one embodiment, please refer to Figure 1 and Figure 3, the rotating pressing member 200 further includes a pressing portion 230, which is movably connected to the push rod 220 in the extending direction of the push rod 220. The pressing portion 230 serves as the direct contact part between the push rod 220 and the pedal 300. Its movably connected design enables the tester to adjust the position and angle of the pressing portion 230 as needed to ensure precise pressure application to the designated area of the pedal 300, thereby contributing to more accurately simulating the operation of the pedal 300 in a real driving scenario and improving the accuracy of the test. Moreover, in some test scenarios, it may be necessary to simulate complex pedal 300 pressing operations, such as pressing multiple points simultaneously or applying pressure in different directions. By adjusting the pressing portion 230, the pressure distribution applied to the pedal 300 can be controlled, enabling the test device to flexibly meet these complex requirements to achieve the testing of various stepping scenarios of the pedal 300, such as forward stepping and side stepping, thus enhancing the comprehensiveness and accuracy of the test. Of course, in other embodiments, the pressing portion 230 can also be fixedly arranged on the push rod 220.
[0047] Furthermore, in this embodiment, please refer to Figure 1 and Figure 3 , the pressing portion 230 is connected to the push rod 220 by a hanging connection. It can be understood that the hanging connection method allows the pressing portion 230 to be quickly and conveniently installed on the push rod 220, and it is also easy to disassemble, improving the flexibility and reconfigurability of the test device, enabling the tester to quickly replace or adjust the pressing portion 230 according to different test requirements. Among them, the hanging connection method usually has strong stability, which can ensure that the pressing portion 230 will not accidentally fall off or become loose during the test. Moreover, the hanging connection method also allows a certain degree of adjustment to adapt to pedals 300 of different sizes, shapes or profiles, thereby enhancing the versatility and practicality of the test device. Of course, in other embodiments, the pressing portion 230 can also be connected to the push rod 220 by a clamping connection, a screwing connection or a melting connection.
[0048] Specifically, in this embodiment, please refer to Figure 1 and Figure 3, the pressing portion 230 includes a hanging joint 231 and a body portion 234. The body portion 234 extends parallel to the rotating arm 210. The hanging joint 231 includes a first wall body 232 and a second wall body 233 that are spaced opposite to each other. The first wall body 232 is connected to the body portion 234. One end of the first wall body 232 away from the body portion 234 is connected to the second wall body 233. The push rod 220 is adaptively inserted between the first wall body 232 and the second wall body 233. It should be noted that the push rod 220 can be connected to at least one of the first wall body 232 and the second wall body 233 to achieve a stable connection between the pressing portion 230 and the push rod 220. The first wall body 232 and the second wall body 233 of the hanging joint 231 together form a stable slot structure, and the push rod 220 is inserted therein, which can ensure the stable and reliable connection between the pressing portion 230 and the push rod 220, that is, it can prevent the pressing portion 230 from falling off or loosening due to uneven force during the test, and ensure the continuity and accuracy of the test. In addition, by adaptively inserting the push rod 220 between the first wall body 232 and the second wall body 233, the rapid installation of the pressing portion 230 can be achieved. This installation method is simple and clear, does not require complex tools or steps, and improves the efficiency of the test preparation work. Similarly, when the pressing portion 230 needs to be replaced or repaired, only need to pull out the push rod 220 from the hanging joint 231, then replace it with a new pressing portion 230 and re-insert it. For the body portion 234, the body portion 234 extends parallel to the rotating arm 210, which is equivalent to extending parallel to the pedal 300, and can better disperse the mutual acting forces between the pressing portion 230 and the pedal 300, improve the service life of the pressing portion 230 and the push rod 220, and reduce the maintenance cost of the test device.
[0049] In one embodiment, please refer to Figure 1The test position 110 is provided with a plurality of limit blocks 160, and the plurality of limit blocks 160 are used to abut against the plurality of peripheral walls of the pedal 300, and the pedal 300 is sandwiched between at least one limit block 160 and the test position 110. It can be understood that the lower surface of the pedal 300 abuts against the test position 110, and the limit blocks 160 abut against the peripheral walls of the pedal 300 in the radial direction. In this way, by abutting against the plurality of peripheral walls of the pedal 300 by the plurality of limit blocks 160, it can be ensured that the pedal 300 maintains a fixed position and posture during the test process, thereby reducing the test error caused by the movement or shaking of the pedal 300 and improving the accuracy of the test. Without loss of generality, the position of the limit block 160 on the test position 110 is adjustable, so that the user can flexibly adjust it according to different test requirements and the size of the pedal 300, thereby improving the versatility and adaptability of the test device. In addition, when the limit block 160 is worn or damaged, the user can easily remove it and replace it with a new limit block 160, which reduces maintenance costs and time costs and improves the efficiency of the test device. Of course, in other embodiments, the test position 110 can also be concavely provided with a limit groove to limit the rotation of the pedal 300 on the test position 110 to ensure the accuracy of the test.
[0050] In one embodiment, please refer to Figure 1 and Figure 2 , the driving member 120 is arranged in the base 100, and is connected to the rotating pressing member 200 through the transmission structure. It can be understood that the driving member 120 and the pedal 300 are arranged on opposite sides of the test position 110, which can make full use of the space inside the base 100, reduce the occupation of the external space, help to achieve the overall structural compactness of the test device or equipment, and facilitate installation and transportation. Among them, the driving member 120 is built into the base 100, and the influence and interference of external factors on the driving member 120 can also be reduced, and the stability and reliability of the driving member 120 are improved. Here, the driving member 120 controls the rotation of the rotating pressing member 200 through the transmission structure, which can ensure that the power of the driving member 120 can be quickly and accurately transmitted to the rotating pressing member 200, and the transmission ratio output by the driving member 120 can also be adjusted, thereby improving the testable range of the test device for different pedals 300. Of course, in other embodiments, the driving member 120 can also be set in the test position 110 to reduce the complexity of the transmission structure and shorten the transmission path.
[0051] Specifically, in this embodiment, please continue to refer to Figure 2, on both the inner and outer sides of the test position 110, the base 100 is provided with mounting protrusions 130. The transmission structure is configured as a transmission rod 170 and two transmission belts 140. The output shaft of the driving member 120 is connected to the transmission rod 170 through a transmission belt 140. The rotating pressing member 200 is rotatably connected to one mounting protrusion 130. One end of the transmission rod 170 is rotatably connected to the other mounting protrusion 130 and is connected to the rotating pressing member 200 through the other transmission belt 140. For the combination of the transmission belt 140 and the transmission rod 170, the power of the driving member 120 can be continuously and smoothly transmitted to the rotating pressing member 200, ensuring the efficiency and stability of power transmission, reducing power loss and energy waste. Among them, the transmission belt 140, as a flexible transmission element, can reduce friction and wear during transmission to a certain extent and extend the service life of the transmission structure. In addition, the mounting protrusions 130 inside and outside the base 100 are used as the support points of the transmission structure to provide support for the rotation of the transmission rod 170 and the rotating arm 210, and save the installation space of the transmission structure. Specifically, through the transmission ratio of the transmission belt 140 and the transmission distance of the transmission rod 170, the rotation angle and speed of the rotating pressing member 200 can be accurately controlled, realizing the control of the torque acting on the rotating pressing member 200, and further improving the accuracy and reliability of the test. Of course, in other embodiments, the transmission structure can also be configured in the form of a gear assembly, which can meet the flexible layout requirements of the driving member 120 and the rotating pressing member 200 while adjusting the transmission ratio.
[0052] The above are only the optional embodiments of the present invention, and do not limit the protection scope of the present invention. Any equivalent structural transformation made by using the content of the specification and drawings of the present invention under the inventive concept of the present invention, or any direct / indirect application in other related technical fields shall be included in the protection scope of the present invention.
