Description

Technical Field

[0001] This utility model relates to the field of robotics technology, and more specifically, to an impact force testing device for a fighting robot. Background Technology

[0002] Wheeled combat robots, as competitive robots powered by a wheeled structure, primarily rely on the magnitude of their impact force for attack performance. In combat sports, the outcome between robots often hinges on the strength of their impact. However, the industry currently lacks specialized testing equipment to accurately measure the impact performance of wheeled combat robots. After completion, designers can only evaluate their attack effectiveness through actual combat, a method that is not only inefficient but also fails to obtain precise impact force data. More importantly, the lack of standardized testing methods makes objective comparisons of the performance of different robots difficult, severely hindering the optimization and improvement of robot design. Particularly in critical areas such as power system debugging and structural strength design, designers often rely solely on experience, lacking scientifically accurate test data for improvement. This situation leads to significant uncertainty in the development of wheeled combat robots, prolonging development cycles and increasing costs. Utility Model Content

[0003] The purpose of this invention is to provide an impact force testing device for fighting robots, which has the advantages of accurately measuring the impact force of fighting robots, improving testing efficiency and data accuracy, and facilitating the optimization of robot design.

[0004] This utility model provides an impact force testing device for a fighting robot, comprising: a testing platform, a linear guide rail, a pressure sensor, a movable seat, and a drive mechanism. The linear guide rail is arranged on the testing platform, the pressure sensor is disposed at one end of the linear guide rail, and the movable seat is movably disposed on the linear guide rail for mounting the fighting robot. The drive mechanism is used to drive the movable seat to move along the linear guide rail so that the fighting robot impacts the pressure sensor.

[0005] The impact force testing device for fighting robots provided by this utility model has, but is not limited to, the following beneficial effects compared with related technologies:

[0006] The impact force testing device for combat robots described in this invention uses a drive mechanism to accelerate the movement of a mobile base along a linear guide rail, causing the combat robot mounted on the mobile base to impact a pressure sensor at a set speed. During the test, the linear guide rail eliminates deviations in the robot's direction of travel, ensuring that the impact point coincides with the central axis of the pressure sensor. The pressure sensor converts the instantaneous impact force into an electrical signal output, which is then used by an external data acquisition system to generate a force-time curve. The sliding fit structure between the mobile base and the linear guide rail allows the robot to move in a single direction, avoiding measurement errors caused by path deviations. Compared with related technologies, traditional testing methods rely on the actual combat environment, resulting in uncontrollable robot trajectories and random impact angles, leading to large data dispersion. This invention limits the movement path through the linear guide rail, ensuring consistency in testing conditions across different batches. The pressure sensor is directly mounted on the impact contact surface, capable of capturing millisecond-level dynamic impact forces, overcoming the lag problem of indirect evaluation methods. Through the above technical solution, this invention achieves quantitative testing of the impact force of combat robots, providing accurate data support for structural optimization. The combination structure of the testing platform and the linear guide rail can be adapted to various robot specifications. The direct measurement method of pressure sensors eliminates human judgment errors, enabling researchers to intuitively obtain impact performance parameters and make targeted improvements to the design.

[0026] It should also be noted that the aforementioned X-axis, Y-axis and Z-axis are used only for the convenience of describing the present invention and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present invention.

[0027] like Figure 1As shown, the impact force testing device for a fighting robot according to an embodiment of this utility model includes: a testing platform 1, a linear guide rail 2, a pressure sensor 3, a movable seat 4, and a driving mechanism 5. The linear guide rail 2 is arranged on the testing platform 1, the pressure sensor 3 is disposed at one end of the linear guide rail 2, the movable seat 4 is movably disposed on the linear guide rail 2, and the fighting robot is mounted on the movable seat 4; the driving mechanism 5 is used to drive the movable seat 4 to move along the linear guide rail 2 so that the fighting robot impacts the pressure sensor 3.

[0028] In this embodiment, in conjunction with the appendix Figure 1 As shown, test platform 1 refers to the basic planar structure supporting linear guide rail 2, used to provide a stable installation reference. Linear guide rail 2 is used to support and guide the moving seat 4 to move linearly in a given direction. Pressure sensor 3 refers to a measuring element that can convert mechanical impact into an electrical signal, specifically a piezoelectric or strain gauge sensor, used to collect impact force data in real time. Moving seat 4 refers to a sliding component that cooperates with linear guide rail 2, used to fix the fighting robot and transmit driving force. Drive mechanism 5 refers to a power device that generates linear motion, such as a belt drive, lead screw, or pneumatic device, used to control the acceleration process of moving seat 4.

[0029] Specifically, the drive mechanism 5 propels the movable base 4 to accelerate along the linear guide rail 2, causing the fighting robot mounted on the movable base 4 to impact the pressure sensor 3 at a set speed. During the test, the linear guide rail 2 eliminates any deviation in the robot's direction of travel, ensuring that the impact point coincides with the central axis of the pressure sensor 3. The pressure sensor 3 converts the instantaneous impact force into an electrical signal output, which is then used by an external data acquisition system to generate a force-time curve. The sliding fit structure between the movable base 4 and the linear guide rail 2 allows the robot to move in a single direction, avoiding measurement errors caused by path deviations.

[0030] Compared to related technologies, traditional testing methods rely on real-world environments, where robot trajectories are uncontrollable and impact angles are random, resulting in large data dispersion. This invention uses linear guides to limit the motion path, ensuring consistent testing conditions across different batches. The pressure sensor 3 is directly mounted on the impact contact surface, capable of capturing millisecond-level dynamic impact forces, overcoming the lag problem of indirect evaluation methods.

[0031] Through the above technical solution, this utility model realizes the quantitative testing of the impact force of fighting robots, providing accurate data support for structural optimization. The combined structure of the test platform 1 and the linear guide rail 2 can be adapted to robots of various specifications, and the speed adjustment function of the drive mechanism 5 (e.g., adjusting the motor speed) can simulate different attack intensity conditions. The direct measurement method of the pressure sensor 3 eliminates human judgment errors, enabling R&D personnel to intuitively obtain impact performance parameters and make targeted improvements to the design.

[0032] Optionally, the drive mechanism 5 includes a motor 51, a transmission belt 52, a driving pulley 53, and a driven pulley 54, wherein the driving pulley 53 and the driven pulley 54 are respectively arranged along the length of the linear guide rail 2 (see attached diagram). Figure 1 At both ends of the X-axis direction, the transmission belt 52 is connected to the driving pulley 53 and the driven pulley 54 respectively. The motor 51 is arranged on the test platform 1, and the output shaft of the motor 51 is connected to the driving pulley 53. The movable seat 4 is connected to the transmission belt 52.

[0033] In this embodiment, in conjunction with the appendix Figure 2 As shown, the driving pulley 53 is the wheel that drives the transmission belt 52 to move by rotating. The driven pulley 54 is the wheel that is passively rotated by the transmission belt 54. The transmission belt 52 is an annular flexible belt used to transmit power; specifically, a rubber synchronous belt or a polyurethane toothed belt can be used to achieve slip-free transmission. The moving seat 4 and the transmission belt 52 can be connected by bolts or clips to fix the moving seat 4 to the surface of the transmission belt 52, thereby transmitting linear motion to the moving seat 4.

[0034] Specifically, after the motor 51 is energized, it drives the active pulley 53 to rotate, which in turn drives the driven pulley 54 to rotate synchronously via the transmission belt 52, thus forming a closed-loop motion trajectory for the transmission belt 52. The movable seat 4 is fixed to the transmission belt 52 by a rigid connector, and it generates displacement along the linear guide rail 2 during the cyclical motion of the transmission belt 52. The transmission belt 52 will cause the movable seat 4, carrying the fighting robot, to collide with the pressure sensor, at which point the pressure sensor records the peak impact force. This transmission method allows the acceleration of the movable seat 4 to be controlled by adjusting the speed of the motor 51; for example, the motor 51 can be set as a stepper motor to achieve graded speed adjustment.

[0035] Optionally, mounting seats 6 are provided at both ends of the linear guide rail 2 along its length. The driving pulley 53 and the driven pulley 54 are rotatably connected in the two mounting seats 6 respectively. The transmission belt 52 extends into the two mounting seats 6 respectively and is connected to the driving pulley 53 and the driven pulley 54 in a transmission connection.

[0036] In this embodiment, in conjunction with the appendix Figure 1 As shown, mounting base 6 refers to the support structure fixed to both ends of the linear guide rail 2. It can be implemented using metal blocks or engineering plastic bases, providing a stable mounting foundation for the pulleys (driving pulley 53 and driven pulley 54). Rotatable connection refers to the pulley forming a rotatable assembly relationship with mounting base 6 through bearings or bushings. Rolling bearings can be used to reduce transmission resistance. The transmission belt 52 extending into the mounting base means that the transmission belt passes through the internal space of mounting base 6 and meshes with the pulleys. This can be achieved by creating through slots or guide structures on the mounting base to limit lateral deviation of the transmission belt.

[0037] Specifically, the mounting base 6 is fixed at both ends of the linear guide rail 2. The driving pulley 53 and the driven pulley 54 are respectively mounted in the corresponding mounting base 6 through bearings. The transmission belt 52 passes through the interior of the mounting base 6 and forms a closed-loop transmission with the pulleys. When the motor 51 drives the driving pulley 53 to rotate, the transmission belt 52 maintains stable operation under the limiting action of the mounting base 6, driving the movable seat 4 to move along the linear guide rail 2. The guiding structure inside the mounting base 6 can constrain the running trajectory of the transmission belt 52, avoiding tooth slippage or other phenomena caused by the transmission belt 52 deviating.

[0038] Optionally, the upper and lower ends of the linear guide rail 2 are respectively provided with grooves 21, and the grooves 21 extend to both ends of the linear guide rail 2 in the length direction. The grooves 21 are configured to accommodate the transmission belt 52.

[0039] In this embodiment, in conjunction with the appendix Figure 1 and attached Figure 3 As shown, groove 21 refers to the groove along the length of linear guide 2 (see attached diagram). Figure 1 The groove structure (in the X-axis direction) is designed to provide space for the transmission belt 52 and prevent the transmission belt 52 from interfering with the external structure during movement.

[0040] The groove 21 extending to both ends of the linear guide 2 means that the starting end and the ending end of the groove 21 are aligned with the two ends of the linear guide 2, thereby ensuring that the transmission belt is under the limiting protection of the groove throughout the entire length of the linear guide 2.

[0041] Specifically, after grooves 21 are machined at the upper and lower ends of the linear guide 2, the transmission belt 52 is confined within the grooves 21. When the drive mechanism 5 moves the transmission belt 52, the sidewalls of the grooves 21 guide the transmission belt 52, preventing it from shifting laterally or derailing during high-speed movement. Simultaneously, the design of the grooves 21 extending to both ends of the linear guide 2 ensures that the transmission belt 52 remains within the constraint range of the grooves 21 when it reaches the end of the linear guide 2, preventing it from colliding with other components due to exceeding the range of the linear guide 2.

[0042] Optionally, a gap is left between the linear guide rail 2 and the test platform 1; the movable seat 4 includes a first upper seat body 41 and a first lower seat body 42, the first lower seat body 42 is disposed below the linear guide rail 2, and a gap is left between the first lower seat body 42 and the test platform 1, the first lower seat body 42 is connected to the transmission belt 52, the first upper seat body 41 is disposed above the linear guide rail 2, and the first upper seat body 41 and the first lower seat body 42 are used to be connected as one unit by a connector.

[0043] In this embodiment, in conjunction with the appendix Figure 1 As shown, the gap between the linear guide rail 2 and the test platform 1 refers to the spatial area formed between them. This gap can be achieved using support blocks or shims to prevent direct contact between the linear guide rail 2 and the test platform 1. The first lower seat 42 is the component located below the linear guide rail 2, used to bear the traction force of the transmission belt 52. The connecting component is the fastening element used to fix the first upper seat 41 and the first lower seat 42. It can be a bolt structure for easy disassembly and adjustment.

[0044] Specifically, the linear guide rail 2 is installed in a non-contact manner with the test platform 1 through a gap. When the drive mechanism 5 drives the transmission belt 52, the first lower seat 42 moves along the linear guide rail 2 with the transmission belt 52. At the same time, the first upper seat 41 and the first lower seat 42 are rigidly connected through a connector, allowing the fighting robot mounted on the first upper seat 41 to move smoothly. During the impact test, the gap avoids frictional interference between the moving seat 4 and the test platform 1, ensuring that the impact force data is accurately collected by the pressure sensor.

[0045] Optionally, a pulley 421 is provided on the first lower seat 42, and the pulley 421 contacts the side wall of the linear guide rail 2.

[0046] In this embodiment, in conjunction with the appendix Figure 1 and attached Figure 2 As shown, pulley 421 refers to a wheel-shaped structure with rolling elements, which reduces frictional resistance through rolling contact. The sidewall of linear guide 2 is the vertical guide surface on both sides of the guide rail, and can be made of surface-hardened steel rail, used to limit the lateral displacement of the moving seat 4.

[0047] Specifically, the first lower seat 42 of the movable seat 4 forms rolling contact with the side wall of the linear guide rail 2 through a pulley 421. When the drive mechanism 5 moves the movable seat 4 along the linear guide rail 2, the pulley 421 rolls along the side wall of the linear guide rail 2, converting sliding friction into rolling friction. This structure can effectively reduce frictional losses during the operation of the movable seat 4, avoid jamming or speed fluctuations caused by sliding friction, and thus ensure the smoothness of the fighting robot's movement during the impact process.

[0048] Optionally, the impact force testing device for the fighting robot further includes a fixed base 7 and a sensor mounting base 8. The fixed base 7 includes a second upper body 71 and a second lower body 72. The second lower body 72 is disposed below one end of the linear guide rail 2 near the driven pulley 54, and the second upper body 71 is disposed above one end of the linear guide rail 2 near the driven pulley 54. The second upper body 71 and the second lower body 72 are connected as one unit by a connector. The sensor mounting base 8 is disposed on the second upper body 71, and the pressure sensor 3 is disposed on the sensor mounting base 8.

[0049] In this embodiment, in conjunction with the appendix Figure 1 As shown, the mounting base 7 refers to the support structure used to fix the sensor mounting base 8. Specifically, it can be implemented using a split design, with the second upper base 71 and the second lower base 72 connected by bolts. This allows it to adapt to the installation space of the linear guide rail 2 and improve structural stability. The sensor mounting base 8 refers to the mounting component used to support the pressure sensor 3.

[0050] Specifically, the second lower seat 72 is fixed below the linear guide 2 near the driven pulley 54 (see attached diagram). Figure 1 (in the opposite direction of the Z-axis), the second upper seat 41 is located above the same end of the linear guide rail 2, and the two can be locked together with bolts to form a clamping and fixing structure. When the moving seat 4 drives the fighting robot to collide with the pressure sensor 3, the rigid support system formed by the fixed seat 7 and the sensor mounting seat 8 can effectively prevent the pressure sensor 3 from being displaced or tilted due to the impact force.

[0051] Optionally, the sensor mounting base 8 includes a horizontal plate 81 and a vertical plate 82 connected to each other. The horizontal plate 81 is connected to the second upper seat body 71, and the pressure sensor 3 is disposed on the vertical plate 82.

[0052] In this embodiment, in conjunction with the appendix Figure 1 As shown, the horizontal plate 81 refers to a plate with a planar support structure, used to be fixedly connected to the second upper body 71 to achieve stable support for the sensor mounting base 8. The vertical plate 82 refers to a plate extending perpendicular to the horizontal plate 81, used to support the pressure sensor 3 and to align its detection surface with the impact direction.

[0053] Specifically, the horizontal plate 81 is fixed to the surface of the second upper body 71 by bolts or welding, the vertical plate 82 extends upward from the middle of the horizontal plate 81 to form a vertical support surface, and the pressure sensor 3 is fixed to the detection area of ​​the vertical plate 82 by screws or clips.

[0054] Optionally, the impact force testing device for the fighting robot also includes a box structure 9 with an opening at the top, and the testing platform 1 is detachably connected to the opening of the box structure 9.

[0055] In this embodiment, in conjunction with the appendix Figure 1 As shown, box structure 9 refers to a shell with a accommodating space, the opening of which is located at the top (see attached diagram). Figure 1 (In the positive direction of the Z-axis), an installation edge is provided at the opening to facilitate docking with the test platform 1. Detachable connection refers to the assembly of components through a separable fixing method, which can be achieved by bolt fastening, snap locking, or slide rail embedding, facilitating the installation and disassembly of the test platform 1.

[0056] Specifically, the housing structure 9 is configured as a support frame to support the test platform 1 and related components. The test platform 1 is fixed to the edge of the opening of the housing structure 9 via connectors. The interior of the housing structure 9 can be used to store related tools.

[0057] Optionally, casters 10 are provided at the four corners of the bottom of the box structure 9.

[0058] In this embodiment, in conjunction with the appendix Figure 1 As shown, the caster wheel 10 refers to a moving wheel with an omnidirectional rotation structure. Specifically, it can be a caster wheel with a braking function, which is fixed to the four bottom corners of the box structure 9 by bolts or buckles to support the box structure 9 and enable multi-directional movement.

[0059] Specifically, after installing casters 10 at the four bottom corners of the housing structure 9, the housing structure 9 can roll freely via the casters 10 when the testing device needs to be moved. For example, when transferring between a laboratory or a competition venue, the entire device can be pushed without disassembling the testing platform 1. The braking function of the casters 10 prevents the device from shifting during testing, ensuring the stability of the impact force test.

[0060] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0061] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
