Description

Technical Field

[0001] The present application relates to the field of testing equipment, and in particular to a device for simulating a human kicking action. Background Art

[0002] A touch-sensitive trunk is a smart car feature that allows users to open and close the trunk with a foot motion, without having to touch the trunk. This feature is particularly useful when hands are limited, such as when carrying heavy items or shopping bags. A touch-sensitive trunk typically uses a kick sensor located under the rear bumper. When the user approaches the vehicle with the key and gently sweeps their foot across a designated area, the trunk automatically opens.

[0003] To improve the success rate and user experience of kicking the trunk open, the calibration parameters of the kick sensor need to be adjusted. This not only increases the success rate of kicking the trunk open, but also prevents accidental opening of the trunk when the vehicle passes over obstacles. Therefore, the kick sensor, mounted below the rear bumper, is subjected to repeated kicking motions. The capacitance change amplitude of the kick sensor when kicking at different positions is measured, and the feedback data is used to set the calibration parameters of the kick sensor.

[0004] Currently, in the statistical process of the automobile market, people usually kick the outside of the rear bumper repeatedly. However, since the action and distance of each kick are relatively random and difficult to standardize, it is not convenient to analyze the collected data, resulting in the difficulty in setting the calibration parameters of the kick sensor. Utility Model Content

[0005] In order to improve the controllability of the simulated kicking action, the present application provides a device for simulating the kicking action of the human body, which can repeatedly simulate the human leg action and adjust the kicking speed, kicking angle or height as needed to match different car models or rear bumpers.

[0006] The present application provides a device for simulating a human kicking action using the following technical solution:

[0007] A device for simulating a human kicking action comprises a frame, a drive assembly, and a first swing arm, a second swing arm, and a foot connected in sequence. The first swing arm is rotatably mounted on the frame, the drive assembly is mounted on the frame, and the drive assembly has a retractable movable end connected to the first swing arm. When the movable end reaches its maximum extension, the foot is within the detection range of a kick sensor under the vehicle bumper.

[0008] By adopting the above technical solution, the first swing arm, the second swing arm and the foot are used to simulate the kicking action of the human body, and the capacitance change amplitude of the kicking sensor is collected through the system to provide a reference for the calibration parameter setting of the kicking sensor; and the action of the device can be standardized, and the kicking speed and kicking position are controllable, making the collected data more convenient for statistical analysis, improving the data value, and avoiding large data differences caused by errors in the position or angle of human kicking, which affects the analysis results, thereby achieving the effect of optimizing the calibration parameters of the kicking sensor and improving the user experience of the induction trunk.

[0009] Optionally, two mounting seats are provided on the frame, a rotating shaft is fixed on the first swing arm, and two ends of the rotating shaft are rotatably mounted on the two mounting seats respectively.

[0010] By adopting the above technical solution, the rotational connection of the first swing arm is achieved by utilizing the cooperation between the mounting seat and the rotating shaft, and the structure is stable, reliable and easy to implement.

[0011] Optionally, the driving assembly includes a cylinder and an articulated seat, the articulated seat is fixed to the frame, the cylinder includes a shell and a piston rod, the shell is rotatably mounted on the articulated seat, and one end of the piston rod is hinged to the first swing arm.

[0012] By adopting the above technical solution, when the piston rod is extended or retracted, the housing and the hinge seat rotate relative to each other, and the piston rod and the first swing arm rotate relative to each other synchronously, so as to ensure the stability of the rotation posture of the first swing arm.

[0013] Optionally, a limit stop is provided at one end of the piston rod away from the first swing arm, and the cross-sectional size of the limit stop is larger than that of the piston rod.

[0014] By adopting the above technical solution, when the piston rod gradually extends, the limit block gradually approaches the shell and finally abuts against the shell. By changing the position of the limit block on the piston rod, the extension length of the piston rod can be adjusted, thereby changing the rotation angle of the first swing arm to simulate the kicking action of the human body in different postures.

[0015] Optionally, the limit stop is screwed to the piston rod.

[0016] By adopting the above technical solution, the screw connection structure is stable and the position of the limit block on the piston rod can be quickly adjusted.

[0017] Optionally, the hinged seat includes a base plate, a rotating frame and two connecting parts, the base plate is arranged on the frame, the two connecting parts are fixed to the base plate and arranged opposite to each other, the rotating frame is sleeved on the shell, and the two ends of the rotating frame are rotatably mounted on the two connecting parts respectively.

[0018] By adopting the above technical solution, the rotating frame is sleeved on the housing, thereby ensuring the stability of the housing during rotation, thereby improving the reliability of the overall structure of the drive assembly.

[0019] Optionally, the frame includes a base, an upper support frame and a lower support frame, and the upper support frame, the lower support frame and the base are connected and fixed in sequence from top to bottom, and the upper support frame, the lower support frame and the base are all frame structures welded from rectangular steel pipes.

[0020] By adopting the above technical solution, the frame structure has sufficient strength and is relatively light, making it easy to turn around.

[0021] Optionally, support legs are provided at the four corners below the base.

[0022] By adopting the above technical solution, the supporting legs form a gap between the base and the ground, making it easier for equipment such as forklifts to move the frame and improving the convenience of device turnover.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. The first and second swing arms and the foot simulate a human kicking motion. The system then collects the capacitance change amplitude of the kick sensor, providing a reference for setting the sensor's calibration parameters. The device's motion is standardized, and the kicking speed and position are controllable. This makes the collected data more convenient for statistical analysis, increasing its value. This avoids significant data discrepancies caused by errors in kicking position or angle, which can affect analysis results. This ultimately optimizes the kick sensor's calibration parameters and improves the user experience of the sensor trunk.

[0025] 2. As the piston rod gradually extends, the limit stop gradually approaches the housing and eventually abuts against it. By changing the position of the limit stop on the piston rod, the extension length of the piston rod can be adjusted, thereby changing the rotation angle of the first swing arm to simulate the kicking action of different human postures;

[0026] 3. By setting the frame as a frame structure with supporting legs at the bottom, the convenience of device turnover can be improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following is combined with Figure 1-2 This application is described in further detail.

[0031] The present application discloses a device for simulating a human kicking action, referring to Figure 1 and Figure 2 , including a frame 1, a driving component 2, and a first swing arm 3, a second swing arm 4 and a foot 5 connected in sequence. The first swing arm 3 is rotatably mounted on the frame 1 at one end away from the second swing arm 4. The first swing arm 3, the second swing arm 4 and the foot 5 are used to simulate the human thigh, calf and foot in sequence. The driving component 2 is mounted on the frame 1 and has a movable end, which is connected to the first swing arm 3. The movable end is extended and retracted to drive the first swing arm 3 to swing back and forth, and then drive the second swing arm 4 and the foot 5 simulating the calf and foot to swing back and forth, so as to realize the simulation of the human kicking action.

[0032] During specific use, the device is placed on the trunk or rear bumper of the vehicle to be tested, and the driving component 2 is used to drive the foot 5 to swing to the detection area of ​​the kick sensor under the rear bumper. The system records the capacitance change amplitude of the kick sensor, and then the driving component 2 drives the foot 5 to reset. Thereafter, the above-mentioned kicking process is repeated. After obtaining a sufficient amount of data, the position of the device is adjusted according to the test needs, and the position and volume of the foot 5 in the kicking action are changed to collect kicking data at different distances and volumes of the foot 5, so as to facilitate more accurate and reasonable calibration parameter setting of the kick sensor.

[0033] Specifically, refer to Figure 1 and Figure 2 Two mounting blocks 6 are fixed to the frame 1. A rotating shaft 7 is mounted on the end of the first swing arm 3 away from the second swing arm 4. The rotating shaft 7 is arranged horizontally, and its ends are rotatably mounted to the two mounting blocks 6 via bearings. Specifically, the end of the rotating shaft 7 is fixed to the inner race of the bearing, and the outer race of the bearing is fixed to the mounting block 6. This ensures rotational coordination between the rotating shaft 7 and the mounting block 6, thus achieving the rotatable mounting of the first swing arm 3. When the movable end of the drive assembly 2 is extended or retracted, the rotating shaft 7 rotates relative to the mounting block 6, causing the first swing arm 3 to swing accordingly, simulating a human kick.

[0034] Further, refer to Figure 1and Figure 2 The first swing arm 3 and the second swing arm 4 are fixedly connected by bolts, and the second swing arm 4 and the foot 5 are also fixedly connected by bolts. By loosening the bolts, the angle between the first swing arm 3 and the second swing arm 4 and the angle between the second swing arm 4 and the foot 5 can be adjusted, thereby further improving the accuracy of imitating the human leg posture and collecting more accurate and reliable data.

[0035] Further, refer to Figure 1 and Figure 2 The first swing arm 3, second swing arm 4, and foot 5 are all hollow structures to reduce overall weight, making it easier for the drive structure to move them, achieving higher-precision movements. Furthermore, the volume of the first swing arm 3, second swing arm 4, and foot 5 can be modified to simulate human legs of different body shapes, further improving the comprehensiveness of data collection.

[0036] Reference Figure 1 and Figure 2 The frame 1 comprises a base 11, an upper support frame 12, and a lower support frame 13. The upper support frame 12, the lower support frame 13, and the base 11 are sequentially connected and fixed from top to bottom to form the frame 1 for mounting the first swing arm 3. The base 11 is a frame-like structure made of crisscrossed rectangular steel pipes welded together, while the upper support frame 12 and the lower support frame 13 are cubic frames made of welded rectangular steel pipes. In other words, the frame 1 is entirely composed of welded rectangular steel pipes, providing a stable structure and a balanced weight, facilitating the overall movement of the device.

[0037] Reference Figure 1 and Figure 2 Support legs 14 are provided at each of the four corners of the base 11. The ends of the support legs 14, which are away from the base 11, have wide, rounded ends to enhance support stability. Furthermore, the support legs 14 create a gap between the base 11 and the ground, making it easier for forklifts and other equipment to move the frame 1, improving the ease of movement of the device.

[0038] Reference Figure 1 and Figure 2 The drive assembly 2 includes a cylinder 21 and an articulated seat 22. The articulated seat 22 is fixed to the upper support frame 12. The cylinder 21 includes a housing 211 and a piston rod 212. The housing 211 of the cylinder 21 is rotatably mounted on the articulated seat 22, while one end of the piston rod 212 is hinged to the first swing arm 3. When the piston rod 212 of the cylinder 21 extends or retracts, it drives the first swing arm 3 to swing. At the same time, the piston rod 212 rotates relative to the first swing arm 3, and the housing 211 rotates relative to the articulated seat 22.

[0039] In this embodiment, cylinder 21 is connected to an air pump, and a three-position, five-way solenoid valve is installed between the connection between cylinder 21 and the air pump to precisely control the position of cylinder 21, thereby improving the movement accuracy of first swing arm 3, second swing arm 4, and foot 5. Furthermore, a magnetic switch or photoelectric sensor is installed on housing 211 to monitor the position of the piston in cylinder 21, thereby coordinating the repeated extension and retraction of piston rod 212.

[0040] Further, refer to Figure 1 and Figure 2 The end of the piston rod 212, away from the first swing arm 3, protrudes from the housing 211 and is provided with a limit stop 213. The limit stop 213 has a larger cross-sectional dimension than the piston rod 212 and is threadedly engaged with the piston rod 212. Rotating the limit stop 213 can adjust its position on the piston rod 212. As the piston rod 212 gradually extends, the limit stop 213 gradually approaches the housing 211. When the piston rod 212 reaches its maximum extension, the limit stop 213 abuts the housing 211. By changing the position of the limit stop 213 on the piston rod 212, the extension length of the piston rod 212 can be adjusted, thereby changing the rotation angle of the first swing arm 3, simulating the kicking action of the human body in different postures.

[0041] Further, refer to Figure 2 The hinged base 22 includes a base plate 221, a rotating frame 222, and two connecting members 223. The base plate 221 is horizontally fixed to the upper support frame 12. The two connecting members 223 are arranged opposite each other and fixed to the base plate 221. The rotating frame 222 has a square frame structure and is sleeved on the housing 211 of the cylinder 21. The rotating frame 222 has a rotating shaft 7 formed at both ends, and the two rotating shafts 7 are rotatably mounted on the two connecting members 223. When the piston rod 212 is extended or retracted, the housing 211 located within the rotating frame 222 rotates synchronously with the rotating frame 222 relative to the connecting members 223, thereby achieving the rotational installation of the cylinder 21.

[0042] Reference Figure 2 A control box 8 is mounted on one side of the lower support frame 13. This box houses a control module, which is electrically connected to the three-position, five-way solenoid valve and the air pump that control the gas flow to the cylinder 21. Furthermore, detection signals from the magnetic switch or photoelectric sensor are transmitted to the control module for signal processing. The photoelectric sensor can be used to detect the position of the piston in the cylinder, detecting any positional anomalies and providing protection. The control box 8 is equipped with a display control screen 81, a start button 82, a stop button 83, and an emergency stop button 84. These buttons are all electrically connected to the control module.

[0043] Among them, the display control screen 81 is used to display the relevant parameters of the device, and can set the piston rod movement speed and dwell time (i.e., the static time after the first swing arm 3, the second swing arm 4 and the foot 5 are extended). According to the static time after the first swing arm 3, the second swing arm 4 and the foot 5 are extended, the kick sensor capacitance change and the kick triggering situation are collected, and the kick sensor parameters are set according to the collected data; pressing the start button 82 can start the air pump to drive the cylinder 21 to work, pressing the stop button 83 can stop the air pump, and pressing the emergency stop button 84 can urgently cut off the power supply of the equipment to respond to emergency situations and quickly stop the equipment operation.

[0044] The implementation principle of the device for simulating a human kicking action disclosed in the embodiment of the present application is as follows:

[0045] Before use, first transport the entire device to the trunk or rear bumper of the vehicle, adjust the distance between the device and the vehicle and the position of the limit block 213, connect the air pump outlet to the air inlet of the three-position five-way solenoid valve, press the start button 82, the air pump drives the piston rod 212 of the cylinder 21 to extend, driving the first swing arm 3 to rotate, thereby swinging the foot 5 to the detection area of ​​the kick sensor, the piston rod 212 repeatedly extends and retracts, and the system records and counts the amplitude of the capacitance change of the kick sensor. After data collection is completed, press the stop button 83 to stop the device;

[0046] The first swing arm 3, the second swing arm 4 and the foot 5 simulate the kicking action of the human body, and the action can be standardized, and the kicking speed and kicking position are controllable, which makes it easier to analyze the collected data, optimize the calibration parameters of the kicking sensor, and thus optimize the user experience of the induction trunk.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
