[0035] The steering system needs the steering wheel's rotation angle and the torque during the rotation process to adapt to the preset requirements in order to provide a good experience for the user. Existing tests usually only detect the torque, and then compare the torque with the rotation angle to obtain the torque distribution structure of the rotation process. However, this post-combination method is prone to large errors. For example, if the torque is balanced or floating over a period of time, while the rotation angle is evenly distributed, the torque is still evenly paired with the rotation angle, which will result in a situation where a certain rotation angle and torque do not correspond, resulting in a large test error. In addition, the post-combination comparison method also increases the difficulty of detection.

[0036] The utility model provides a steering system testing device.

[0037] In the embodiment of the present utility model, please refer to Figures 1 to 4 The steering system test device is used to test the steering system. The steering system includes a driving member 300 and a steering wheel 400 connected in a transmission manner. The steering system test device includes:

[0038] The base 100 has a placement position 111 on the upper portion of the base 100, and the placement position 111 is used for limiting the placement of the driving member 300;

[0039] A test workpiece 200, the test workpiece 200 comprises a clamping member 220, a sensor 230 and a test driving member 240, the test driving member 240 is transmission-connected to the clamping member 220, the clamping member 220 is used to clamp the steering wheel 400, and is fixed with the steering wheel 400 in the circumferential upper limit direction, and the sensor 230 is used to detect the torque output by the driving member 300 and the rotation angle of the steering wheel 400; and

[0040] The control module is electrically connected to the sensor 230 and the test driver 240 , and is used to obtain the detection value of the sensor 230 and control the operation state of the test driver 240 .

[0041] The technical solution of the present utility model is to set a placement position 111 on the base 100, and a clamping member 220 is arranged at a position opposite to the placement position 111. A steering system is placed between the clamping member 220 and the placement position 111 in a limited manner. Among them, the driving member 300 is stably limited to the placement position 111, the steering wheel 400 is clamped by the clamping member 220 and is circumferentially fixed with the clamping member 220. Then, the test workpiece 200 is also provided with a sensor 230 for detecting the torque output from the driving member 300 to the steering wheel 400 and synchronously detecting the rotation angle of the steering wheel 400. During the process of the driving member 300 driving the steering wheel 400 to rotate, the sensor 230 can obtain detection values such as the rotation angle of the steering wheel 400 and the torque during the rotation process, and transmit the detection values to the control module. When the steering wheel 400 rotates to the limit position, the control module can control the test driving member 240 to perform a stall test according to the torque currently output by the driving member 300, and then calibrate and detect the parameters of the driving member 300 under various working conditions to ensure the performance of the driving member 300. In this way, the rotation angle, torque of the steering wheel 400 and the stall test of the driving member 300 are completed with a single operation, and the real-time torque of the steering wheel 400 at each rotation angle can be accurately reflected, thereby reducing the detection error and improving the convenience of detection.

[0042] Among them, the test workpiece 200 can be arranged on the base 100 or independently of the base 100, so that the steering system test device is set as a component. Regardless of the connection relationship between the test workpiece 200 and the base 100, it can be understood that during the test, the relative position relationship between the clamping member 220 and the placement position 111 remains stable. In addition, when the control module obtains the detection values of the sensor 230, including parameters such as the torque and rotation angle of the steering wheel 400, 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 steering wheel 400 will be detected under different output powers of the driving member 300. In each detection process, when the steering wheel 400 rotates to the limit position, the control module will control the test driving member 240 to operate according to the current output power of the driving member 300 and the torque of the steering wheel 400, and realize the stall test of the driving member 300 by controlling the variables of the driving member 300. Specifically, both the driving member 300 and the test driving member 240 are motors. Of course, in some cases, the driving member 300 and the test driving member 240 can also be cylinders or oil cylinders, etc.

[0043] It should be noted that the sensor 230 can integrate the functions of torque and angle detection, or can be a separate torque sensor 230 and angle sensor 230. The sensor 230 can be arranged on the clamping member 220, or the torque sensor 230 is arranged on the clamping member 220, and the angle sensor 230 is arranged on the relative member of the steering wheel 400 and the test workpiece 200. It can be understood that the driving member 300 is at least circumferentially limited and fixed on the placement position 111, and the placement position 111 is stable on the base 100, so as to prevent the driving member 300 from rotating or moving during the test, resulting in a large error in torque measurement. In addition, the steering system referred to in this solution refers to a steering device including the driving member 300 and the steering wheel 400. The driving member 300 applies torque to the steering wheel 400, and the user obtains an actual driving experience when turning the steering wheel 400. This can be used in the assisted driving of automobiles or in the driving games of automobile simulation.

[0044] In one embodiment, please refer to Figures 1 to 3 , a plurality of limiting blocks 112 are detachably arranged on the placement position 111, and the plurality of limiting blocks 112 are used to abut against the plurality of peripheral walls of the driving member 300. It can be understood that the lower surface of the driving member 300 abuts against the placement position 111, and the limiting blocks 112 abut against the peripheral wall of the driving member 300 in the radial direction, forming a connection relationship such as that between the clamping member 220 and the steering wheel 400. In this way, by abutting against the peripheral wall of the driving member 300, the limiting blocks 112 can accurately limit the position of the driving member 300 on the placement position 111, thereby ensuring that the driving member 300 maintains a stable posture and position during the test and avoiding test errors caused by position deviation. Without loss of generality, the position of the limiting blocks 112 on the placement position 111 is adjustable, so that the user can flexibly adjust according to different test requirements and the size of the driving member 300, improving the versatility and adaptability of the test device. In addition, when the limiting blocks 112 are worn or damaged, the user can easily disassemble and replace them with new limiting blocks 112, reducing the maintenance cost and time cost and improving the use efficiency of the test device. Of course, in other embodiments, a limiting groove can also be recessed on the placement position 111 to limit the rotation of the driving member 300 on the placement position 111 and ensure the accuracy of the test.

[0045] In one embodiment, please refer to Figures 1 to 3, the test drive member 240 and the clamping member 220 are drivingly connected through a coupling 250, and the sensor 230 is disposed on the coupling 250. It can be understood that the coupling 250, as a driving connection member, can ensure stable transmission between the test drive member 240 and the clamping member 220. Additionally, the coupling 250 also has a certain buffering and vibration damping effect, capable of absorbing part of the impact and vibration during transmission, protecting the steering system and the test device from damage. Moreover, by adjusting the installation position and angle of the coupling 250, the coaxiality between the test drive member 240 and the clamping member 220 can be ensured, improving the accuracy and efficiency of transmission, thereby guaranteeing the accuracy of the test. Since the coupling 250 is in a key position in the transmission chain, and the sensor 230 is disposed on the coupling 250, the sensor 230 can obtain the most accurate and real measurement data, and can also simplify the structural design of the test device, improve the integration degree, and further facilitate the installation, debugging, and maintenance work of the sensor 230. Of course, in other embodiments, the sensor 230 can also be disposed at other positions of the coupling 250 at the connection shaft between the clamping member 220 and the test drive member 240.

[0046] In one embodiment, please refer to Figures 1 to 3 , the test workpiece 200 further includes a mounting post 210, and the mounting post 210 is connected to the base 100, and the clamping member 220 and the test drive member 240 are disposed on the mounting post 210. The mounting post 210, as the main support structure of the test workpiece 200, is connected to the base 100, providing a stable mounting platform for the clamping member 220 and the test drive member 240. Moreover, the addition of the mounting post 210 enhances the overall rigidity of the test device, enabling it to resist greater torque and force during the test, ensuring the accuracy and reliability of the test. Without loss of generality, the mounting post 210 is detachably connected to the base 100. Here, the mounting post 210 can be designed in an adjustable form, such as height adjustment, angle adjustment, etc., to adapt to the test requirements of different models and specifications of the steering system. At the same time, through the precise design and positioning of the mounting post 210, the relative positions of the clamping member 220 and the test drive member 240 during the test can be ensured to remain unchanged, thereby avoiding measurement errors caused by position deviation. Of course, in other embodiments, the clamping member 220 can also be not connected to the base 100, but rely on an external mounting structure to ensure the relative stability between the clamping member 220 and the base 100.

[0047] In one embodiment, please refer to Figures 1 to 3, a transmission 260 is further provided at the output end of the test drive member 240, and the transmission 260 is in transmission connection with the clamping member 220. It can be understood that the transmission 260 enables the test drive member 240 to output various combinations of speed and torque. In this way, the output speed and torque of the test drive member 240 can be precisely controlled, so as to achieve precise testing of the performance of the steering system, especially to complete the stall test of the drive member 300. At the same time, the transmission 260 allows the tester to select appropriate speed ratios and torque output modes according to different test requirements, so as to achieve multi-mode testing of the performance of the steering system. In addition, the transmission 260 usually has the ability to quickly switch speed ratios, enabling the tester to complete tests under various working conditions in a short time, improving the test efficiency. Moreover, the overload protection ability of the transmission mechanism in the transmission 260 can be utilized. When the test drive member 240 outputs too large a torque, the transmission 260 can automatically adjust the speed ratio or cut off the power transmission to prevent damage to the test equipment and the steering system. Of course, in other embodiments, when ensuring that the test drive member 240 has sufficient output power, the test drive member 240 can also be directly in transmission connection with the clamping member 220.

[0048] In one embodiment, the clamping member 220 includes a clamping body 221 and a clamping block 222. The clamping body 221 has a connection end 223 extending along the radial direction of the steering wheel 400, and the clamping block 222 is arranged at the connection end 223 for pressing tightly against the steering wheel 400 towards the center of the steering wheel 400 in the radial direction. It can be understood that the clamping member 220 can stably clamp the steering wheel 400, preventing the steering wheel 400 from loosening or shifting due to vibration or external forces during the test, and ensuring the accuracy of the test. Without loss of generality, the clamping block 222 is usually designed in a shape with a relatively large contact area with the steering wheel 400 to ensure uniform force during the clamping process, which helps to reduce the deformation or damage of the steering wheel 400 caused by excessive local force and also improves the accuracy of the test. Specifically, the clamping body 221 is provided with at least two connection ends 223. Among them, when there are two connection ends 223, they are radially distributed, and when there are more than three connection ends 223, they are circumferentially evenly distributed. Of course, in other embodiments, a limiting groove can also be provided on the clamping member 220, and the steering wheel 400 is adaptively clamped in the limiting groove so that the clamping member 220 and the steering wheel 400 maintain circumferential stability.

[0049] Further, in this embodiment, please refer to Figures 1 to 3, the clamping block 222 is provided with an arc groove on the side facing the steering wheel 400, and the arc groove is arranged in a conformal manner with the outer ring of the steering wheel 400. The conformal design of the arc groove and the outer ring of the steering wheel 400 ensures that the clamping block 222 can fit tightly and accurately on the steering wheel 400, which not only reduces the shaking caused by the gap, improves the stability and accuracy of the clamping, but also improves the convenience of connection between the clamping piece 220 and the steering wheel 400. In addition, since the outer ring shapes of different steering wheels 400 may be different, the conformal design of the arc groove enables the clamping block 222 to flexibly adapt to different models of steering wheels 400, thereby improving the versatility and flexibility of the test device. In this way, the arc groove is arranged to conform to the outer periphery of the steering wheel 400, which ensures the reliability of the test results, and the two are adapted to each other, which improves the connection efficiency of the clamping piece 220 and the steering wheel 400, thereby improving the test efficiency and accuracy of the steering system.

[0050] In this embodiment, please refer to Figure 1 , the clamping block 222 is detachably connected to the clamping body 221. In this way, the clamping blocks 222 of different specifications or shapes can be quickly replaced according to different test requirements, so that the test device can flexibly adapt to steering wheels 400 of different models and specifications, improve the versatility and flexibility of the test, and reduce the test errors caused by unstable clamping or clamping deviation. At the same time, when a clamping block 222 is damaged or needs to be repaired, it is only necessary to replace the clamping block 222 without replacing the entire clamping mechanism, thereby saving the cost of repair and replacement. Of course, in other embodiments, the clamping block 222 and the clamping body 221 can also be integrally formed.

[0051] Specifically, in this embodiment, please refer to Figures 1 to 3 , the connection end 223 is provided with a plurality of connection holes 224 distributed along the radial direction of the steering wheel 400, and the clamping block 222 is connected to the corresponding connection end 223 through some of the connection holes 224 by screw locking. It should be noted that the plurality of connection holes 224 are distributed along the radial direction of the steering wheel 400, so that the appropriate connection holes 224 can be selected for installation according to the actual size and shape of the steering wheel 400, so that it can flexibly adapt to steering wheels 400 of different models and specifications, thereby improving the versatility and flexibility of the test. At the same time, the connection hole 224 also provides positioning for the installation of the clamping block 222, which is convenient for the connection between the clamping block 222 and the clamping body 221. In addition, the screw locking method makes the installation and disassembly of the clamping block 222 simple and quick, and can also ensure the connection stability of the clamping block 222 and the clamping body 221. Of course, in other embodiments, the clamping block 222 and the clamping body 221 can also be connected by a clamping method.

[0052] In one embodiment, please refer to Figures 1 to 3The base 100 includes a base 100 body and a placement plate 110, a placement position 111 is formed on the side of the placement plate 110 facing the test workpiece 200, and the placement plate 110 is movably connected to the base 100 body along the distribution direction of the clamping member 220 and the placement position 111. Since the placement plate 110 is movably connected to the base 100 body, the position or angle of the placement plate 110 can be adjusted according to the actual size and shape of the steering system, so as to ensure that the spacing between the placement position 111 and the clamping member 220 is adapted to steering systems of different specifications, thereby improving the adaptability of the test device to test workpieces 200 of different sizes and shapes. In addition, the placement plate 110 also provides a positioning reference for the placement of the steering system, which is convenient for testing operations. Of course, in other embodiments, the position of the clamping member 220 can also be adjusted along the distribution direction of the clamping member 220 and the placement position 111, so that the spacing between the placement position 111 and the clamping member 220 is adapted to steering systems of different specifications, thereby improving the applicability of the test device.

[0053] Further, in this embodiment, please refer to Figures 1 to 3 , a transmission member is provided in the body of the base 100, and a turntable 120 is also provided in the body of the base 100, and the turntable 120 is connected to the placement plate 110 through the transmission member to lift the placement plate 110. It should be noted that in this embodiment, the base 100 and the clamping member 220 are distributed in the vertical direction, and the clamping member 220 is located at the upper part of the base 100. Through the rotation of the turntable 120, the transmission member can drive the placement plate 110 to move up and down, thereby adjusting the height of the placement plate 110 to adapt to steering systems of different specifications. In this way, through the cooperation of the turntable 120 and the transmission member, the tester only needs to simply operate the turntable 120 to realize the lifting and lowering of the placement plate 110, without the need for complex adjustment and calibration work, thereby improving the convenience of the user to perform test installation. Of course, in other embodiments, a lifting motor can also be provided in the base 100, and the lifting motor can control the lifting and lowering of the placement plate 110, and a button is provided on the base 100 to control the operation of the lifting motor.

[0054] Specifically, in this embodiment, please refer to Figures 1 to 3, the turntable 120 and the placement plate 110 are arranged on the same side of the base 100 body. The turntable 120 is provided with a gripping column 121 for the user to hold. The placement plate 110 is connected to the base 100 body through a lifting column 130, and the lifting column 130 and the turntable 120 are connected through a transmission member. The turntable 120 and the placement plate 110 being on the same side of the base 100 body allows the user to visually see and access them directly during operation. This layout reduces the visual obstacles and body movements of the user during operation. Moreover, the user can easily rotate the turntable 120 through the gripping column 121, and then drive the lifting of the lifting column 130 through the transmission member to realize the height adjustment of the placement plate 110, thereby improving the convenience of operation. Additionally, the lifting column 130 can stably support the placement plate 110 and the steering system thereon, ensuring the stability and safety of the test. Without loss of generality, the transmission member can be configured as a lead screw. The turntable 120 drives the lead screw to rotate, and the lead screw drives the lifting column 130 to rotate to achieve lifting, such as worm drive between the turntable 120 and the lead screw, and between the lead screw and the lifting column 130.

[0055] The above are only optional embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly.
