Description

[0002] The clutch brake pedal assembly is one of the control mechanisms used by the driver to control the vehicle; for example: in the prior art, a patent document with the name of a pedal assembly, application number 201820062229.1 is provided, and a patent document with the name of an automobile brake clutch pedal assembly, application number 201420566026.8 is provided; in the above two patent documents, a structure of a clutch brake pedal assembly is disclosed respectively.

[0003] The clutch brake pedal assembly includes a pedal mechanism (at least including a clutch pedal, a clutch pedal arm, a brake pedal, and a brake pedal arm), a brake master valve, a clutch master pump, a clutch switch, a brake light switch, and the like. Before the clutch brake pedal assembly is installed on the vehicle, the performance and parameters of the clutch brake pedal assembly need to be detected to determine whether the detected clutch brake pedal assembly is qualified.

The force value and the angle value are detected by the angle sensor;

[0005] However, in the above prior art, the error of the detected force value and angle value is relatively large, and the substantial reason is that, on the one hand, when the pedal assembly is installed on the automobile pedal detection device, the installation position of the pedal assembly relative to the automobile pedal detection device deviates, and on the other hand, during the rotation of the pedal arm, the pedal arm is not a straight line shape but a curved shape, which causes the deviation between the angle of the swing arm rotation and the angle of the pedal arm rotation.

[0069] Embodiment 1

[0070] In the embodiment, a detection device for a clutch brake pedal assembly is provided to solve the technical problem of how to improve the detection accuracy of the pedal assembly.

[0071] Specifically, referring to Figures 1 to 5 , Figure 17 The detection device for a clutch brake pedal assembly of the embodiment comprises a control mechanism 1, a support mechanism 2 and a swing arm mechanism 3.

[0072] The support mechanism 2 is provided with at least a mounting frame 211 for mounting the clutch brake pedal assembly, a first adjusting structure 22 for adjusting the position of the mounting frame 211 on the X-axis of a three-dimensional coordinate system, a second adjusting structure 23 for adjusting the position of the mounting frame 211 on the Y-axis of the three-dimensional coordinate system, and a third adjusting structure 24 for adjusting the position of the mounting frame 211 on the Z-axis of the three-dimensional coordinate system. The mounting surface of the mounting frame 211 for mounting the clutch brake pedal assembly is parallel to the XZ plane of the three-dimensional coordinate system.

[0073] The number of the swing arm mechanism 3 is two, and the two swing arm mechanisms 3 are respectively arranged on both sides of the mounting surface. Each of the swing arm mechanisms 3 is provided with a transmission shaft 301, a swing arm 302, an angle encoder 4 and a pressure sensor 5. The transmission shaft 301 is coaxially provided with a mounting groove 303 for coaxially mounting a laser positioner. The angle encoder 4 is coaxially connected with the transmission shaft 301. One end of the swing arm 302 is connected to the transmission shaft 301, and the other end of the swing arm 302 is provided with the pressure sensor 5.

[0074] The angle encoder 4 and the pressure sensor 5 are electrically connected with the control mechanism 1.

[0075] In this embodiment, the control mechanism 1 is used to at least send a driving signal to the swing arm mechanism 3, so that the swing arm mechanism 3 can generate rotation, and the control mechanism 1 is at least electrically connected with the angle encoder 4 and the pressure sensor 5, so that the control mechanism 1 can receive the angle data of the angle encoder 4 and the pressure data of the pressure sensor 5, and can calculate according to the received angle data and pressure data; the control mechanism 1 can adopt the control mechanism 1 in the prior art, including but not limited to PLC (programmable controller), single-chip microcomputer, industrial computer, etc.

[0076] In this embodiment, the support mechanism 2 is used to install the clutch brake pedal assembly; the mounting structure of the support mechanism 2 for installing the clutch brake pedal assembly can adopt the mounting structure in the prior art, including bolt connection, clamping connection, etc.; in the following content, a quick clamp 6 is provided as the mounting structure for installing the clutch brake pedal, which is not mentioned here for the time being.

[0077] Since there is inevitably an error when the clutch brake pedal assembly is installed on the support mechanism 2, the axis of the transmission shaft 301 of the pedal arm of the clutch brake pedal assembly and the axis of the transmission shaft 301 of the swing arm mechanism 3 are in a non-coaxial state.

[0078] In this embodiment, referring to Figure 1 or Figure 2 When the clutch brake pedal assembly is installed on the support mechanism 2, the worker installs the laser positioner in the mounting groove 303 of the transmission shaft 301, and the worker starts the laser positioner; referring to Figure 16 The laser positioner preferably adopts a laser positioner capable of emitting cross laser G; referring to Figure 16 Since the mounting groove 303 coaxially installs the laser positioner, the intersection of the cross laser G emitted by the laser positioner is collinear with the axis of the transmission shaft 301; the cross laser G emitted by the laser positioner can be irradiated on the end of the hinged shaft of the pedal arm of the clutch brake pedal assembly, and the cross laser G is positioned with the axis of the end of the hinged shaft;

[0079] It should be understood that the shell of the laser positioner can be manufactured as a cylinder, or can be manufactured as a rectangle or other shapes, so that the shape of the mounting groove 303 should match the shape of the shell of the laser positioner, as long as the intersection of the cross laser G of the laser positioner is collinear with the axis of the transmission shaft 301 when the laser positioner is installed in the mounting groove 303.

[0080] Referring to Figure 16 If the axis of the hinged shaft of the current pedal arm and the axis of the transmission shaft 301 of the swing arm mechanism 3 are in a non-coaxial state, the worker should adjust the support mechanism 2, so that the axis of the hinged shaft and the axis of the transmission shaft 301 change from a non-coaxial state to a coaxial state;

[0081] Specifically, referring to Figure 4 or Figure 16 , the cross laser G emitted by the laser positioner is irradiated on the end of the hinged shaft of the pedal arm along the Z-axis direction of the three-dimensional coordinate system, if the intersection point of the cross laser G is located on the upper or lower part of the axis center line of the hinged shaft, then the staff should adjust the third adjusting structure 24 of the support mechanism 2, so that the third adjusting structure 24 can drive the mounting frame 211 to make the positive or negative movement along the Z-axis direction in the process of adjustment, so that the axis center line of the hinged shaft is located on the same horizontal plane as the intersection point of the cross laser G;

[0082] Similarly, referring to Figure 4 or Figure 16 , along the Y-axis direction of the three-dimensional coordinate system, if the intersection point of the cross laser G is located on the front or rear part of the axis center line of the hinged shaft, then the staff should adjust the second adjusting structure 23 of the support mechanism 2, so that the second adjusting structure 23 can drive the mounting frame 211 to make the positive or negative movement along the Y-axis direction in the process of adjustment, so that the axis center line of the hinged shaft is located on the same vertical plane as the intersection point of the cross laser G;

[0083] Referring to Figure 16 , when the intersection point of the cross laser G is located on the same horizontal plane as the axis center line of the hinged shaft, and the intersection point of the cross laser G is located on the same vertical plane as the axis center line of the hinged shaft, the intersection point of the cross laser G coincides with the axis center line of the hinged shaft, indicating that the current transmission shaft 301 of the swing arm mechanism 3 and the hinged shaft of the pedal arm of the clutch brake pedal assembly installed on the support mechanism 2 have formed a coaxial state.

[0084] It should be understood that the aforementioned laser positioner can adopt a laser positioner capable of emitting a linear laser, but in the process of using the linear laser to irradiate the end of the hinged shaft of the pedal arm and adjusting the position of the clutch brake pedal assembly through the support mechanism 2, first, the linear laser emitted by the laser positioner needs to be adjusted to be parallel to the horizontal plane, then the third adjusting structure 24 is adjusted according to the position of the linear laser relative to the axis center line of the hinged shaft, and after the linear laser and the axis center line of the hinged shaft are on the same horizontal plane, the linear laser needs to be adjusted again to be parallel to the vertical plane, and then the second adjusting structure 23 is adjusted according to the position of the linear laser relative to the axis center line of the hinged shaft; the efficiency of positioning adjustment by the laser positioner using the linear laser is lower than that of the aforementioned laser positioner using the cross laser G.

[0085] After the clutch brake pedal assembly is installed on the support mechanism 2, the swing direction of the swing arm 302 of the swing arm mechanism 3 is limited to swing along the YZ plane of the three-dimensional coordinate system (see Figure 1), the swing direction of the pedal and the pedal arm of the clutch brake pedal assembly is limited to rotate along the YZ plane of the three-dimensional coordinate system; the swing arm 302 receives the kinetic energy of the transmission shaft 301 to generate a rotation tendency, the swing arm 302 is in contact with the pedal of the clutch brake pedal assembly installed on the support mechanism 2, so that the swing arm 302 drives the pedal and the pedal arm to rotate; because the transmission shaft 301 of the swing arm mechanism 3 and the hinged shaft of the pedal arm have been arranged in a coaxial state by the aforementioned laser positioner, the swing arm 302 and the pedal arm actually form a coaxial rotation state, in other words, during the simultaneous rotation of the swing arm 302 and the pedal arm, the contact position of the swing arm 302 with the pedal on the pedal arm does not change, so that the torque formed by the force applied by the swing arm 302 to the pedal arm does not change.

[0086] In this embodiment, referring to Figure 1 or Figure 17 The pressure sensor 5 is arranged on the swing arm 302 and is used to contact the pedal on the pedal arm; when the swing arm 302 generates a rotation tendency, the swing arm 302 applies kinetic energy to the pedal on the pedal arm through the pressure sensor 5, and then the pedal drives the pedal arm to rotate after receiving the kinetic energy; during the rotation of the pedal arm, the pressure sensor 5 receives the reaction force of the pedal to generate a pressure electric signal, and sends the pressure electric signal to the control mechanism 1, so that the control mechanism 1 obtains pressure data.

[0087] In this embodiment, referring to Figure 1 or Figure 17 The angle encoder 4 is coaxially arranged on the transmission shaft 301, and during the rotation of the transmission shaft 301, the angle encoder 4 can receive the kinetic energy of the transmission shaft 301 to generate an angle electric signal, and send the angle electric signal to the control mechanism 1, so that the control mechanism 1 obtains angle data.

[0088] In the prior art (a kind of automobile pedal detection device, application number is 201620164841.0), because the clamping part (used for clamping pedal assembly) of the automobile pedal detection device thereof does not have an adjusting structure, so when the pedal assembly is installed on the clamping part, the installation error cannot be reduced by adjusting the position of the pedal assembly, so the axis of the swing shaft of the swing arm and the axis of the pedal arm of the pedal assembly are in a non-coaxial state with relatively large installation error, wherein the rotation angle of the pedal arm detected by the prior art and the actual rotation angle of the pedal arm form a phenomenon of large rotation angle error due to the relatively large installation error, causing the negative effect of low angle detection accuracy of the angle encoder 4.

[0089] The detection device for the clutch brake pedal assembly of the embodiment, by setting the support mechanism 2 with the second adjusting structure 23 and the third adjusting structure 24, and correspondingly setting the mounting groove 303 for coaxially installing the laser positioner on the transmission shaft 301 of the swing arm mechanism 3, so that after the clutch brake pedal assembly is installed on the support mechanism 2, even if there is an installation error, it can be adjusted through the laser positioner, the second adjusting structure 23 and the third adjusting structure 24, which reduces the installation error, and after reducing the installation error, the rotation angle of the swing arm 302 and the rotation angle of the pedal arm form a phenomenon that the rotation error is relatively small, which improves the detection precision of the rotation angle of the pedal arm.

[0090] In the prior art (a kind of automobile pedal detection device, application number is 201620164841.0), since the pedal arm of the pedal assembly detected by the automobile pedal detection device is a curve shape, and the swing arm clamps the pedal arm through the fork piston cylinder, so that in the process that the swing arm drives the pedal arm to rotate through the fork piston cylinder, the contact position of the fork piston cylinder relative to the pedal arm appears displacement, from the force angle of the pedal arm, since the contact position of the fork piston cylinder relative to the pedal arm appears displacement, it causes the moment formed after the pedal arm is stressed to change, and further causes the force value detected by the torque sensor to appear a relatively large error, which forms a negative effect of low force value detection precision of the pedal arm.

[0091] The detection device for the clutch brake pedal assembly of the embodiment, by the second adjusting structure 23 and the third adjusting structure 24 of the support mechanism 2 and the positioning groove of the coaxially installed laser positioner, after adjusting the position of the clutch brake pedal assembly, then directly applying force to the pedal through the pressure sensor 5 on the swing arm 302, since the rotation error formed by the rotation angle of the swing arm 302 and the rotation angle of the pedal arm is relatively small, the swing arm 302 and the pedal arm form a coaxial rotation state with relatively small rotation error, and further make the pressure sensor 5 relative to the pedal keep relatively static or approximately relatively static state, avoid or reduce the phenomenon of moment change caused by the change of the contact position of the pressure sensor 5 and the pedal, improve the detection precision of the force value of the pedal arm.

[0092] In addition, the first adjusting structure 22 of the embodiment is used to adjust the position of the mounting frame 211 on the X axis of the three-dimensional coordinate system; when detecting a plurality of different models of clutch brake pedal assemblies, after a clutch brake pedal assembly of one model is mounted on the support mechanism 2, the positions of the clutch pedal and the brake pedal of the clutch brake pedal assembly relative to the two pressure sensors 5 of the swing arm mechanism 3 are in a biased state, for example, the positions of the clutch pedal and the brake pedal relative to the two pressure sensors 5 are simultaneously left-biased or right-biased, which causes the two pressure sensors 5 to fail to contact the clutch pedal, respectively. At this time, the position of the mounting frame 211 on the X axis can be adjusted by the first adjusting structure 22, so that the clutch brake pedal assembly mounted on the mounting frame 211 moves leftward or rightward, until the clutch pedal and the brake pedal are contacted by one of the pressure sensors 5, respectively.

[0093] In the prior art (an automobile pedal detection device, application number 201620164841.0), because the clamping part (used for clamping the pedal assembly) of the automobile pedal detection device does not have an adjusting structure, after the pedal assembly is mounted on the clamping part, the position of the yoke piston cylinder relative to the two pedal arms (clutch pedal arm and brake pedal arm) can only be changed by adjusting the first slide rail and the second slide rail. Because the yoke piston cylinder is arranged on the first slide rail and the second slide rail through the swing arm, the motor, and the motor fixing part, the adjustment of the first slide rail changes the position of the swing axis of the swing arm 302 on the Y axis of the three-dimensional coordinate system, and the adjustment of the second slide rail changes the position of the swing axis of the swing arm 302 on the X axis of the three-dimensional coordinate system. Under the condition of adjusting the first slide rail, the mounting error of the swing axis of the swing arm 302 and the axis of the pedal arm of the pedal assembly is further increased, which further reduces the angle detection accuracy.

[0094] When the first adjusting structure 22 of the embodiment changes the position of the mounting frame 211, only the position of the mounting frame 211 on the X axis of the three-dimensional coordinate system is changed, and the position of the mounting frame 211 on the Y axis of the three-dimensional coordinate system is not changed. For the above-mentioned prior art, the first adjusting structure 22 of the embodiment does not increase the mounting error of the axis of the transmission shaft 301 and the hinged shaft of the pedal arm, and ensures the angle detection accuracy.

[0095] Further, how to form the first adjusting structure 22, the second adjusting structure 23, and the third adjusting structure 24 in the foregoing technical solutions is preferably achieved by the following technical solutions.

[0096] Referring to Figures 3 to 5 The detection device for the clutch brake pedal assembly of the embodiment further comprises a support assembly 25, a transition assembly 26, and a sliding assembly 27.

[0104] When the transition assembly 26 is connected to the mounting frame 211 through the first positioning component D1, the first positioning component D1 penetrates the first adjusting slot 261 and is inserted into the first connecting hole 212, at this time, the mounting frame 211 forms a first sliding pair with the transition assembly 26 through the first positioning component D1, and the first positioning component D1 can slide in the first adjusting slot 261;

[0107] In the actual process of adjusting the position of the mounting frame 211, if it is necessary to adjust the position of the mounting frame 211 on the X-axis of the three-dimensional coordinate system, the position of the mounting frame 211 relative to the transition assembly 26 can be adjusted through the first sliding pair, if it is necessary to adjust the position of the mounting frame 211 on the Y-axis of the three-dimensional coordinate system, the position of the mounting frame 211, the transition assembly 26 and the support assembly 25 relative to the guide part 272 can be adjusted through the second sliding pair, if it is necessary to adjust the position of the mounting frame 211 on the Z-axis of the three-dimensional coordinate system, the position of the mounting frame 211 and the transition assembly 26 relative to the support assembly 25 can be adjusted through the third sliding pair.

[0109] The third positioning component D3 is specifically a third bolt, and the third connecting hole 251 is specifically a third threaded hole. In the direction of the Y axis of the three-dimensional coordinate system, the third adjusting groove 262 penetrates the transition assembly 26, the shank of the third bolt penetrates the third adjusting groove 262, and the third bolt is in threaded connection with the third threaded hole;

[0110] The sliding part 271 includes a linear bearing 2711 and two connecting plates 2712, and each of the two connecting plates 2712 is provided with a sliding through hole and a connecting lug. The connecting lug is used for being connected to the support assembly 25 through a bolt. The guide part 272 is provided with a light rod 2721 and two positioning blocks 2722, and each of the two positioning blocks 2722 is provided with a mounting through hole. The mounting through hole of each of the two positioning blocks 2722 is sleeved with one end of the light rod 2721. The linear bearing 2711 and the two connecting plates 2712 together form a second sliding pair with the light rod 2721. In the direction of the Y axis of the three-dimensional coordinate system, the two connecting plates 2712 are located at two ends of the linear bearing 2711 and are connected to the support assembly 25, respectively. In the direction of the Z axis of the three-dimensional coordinate system, the linear bearing 2711 is connected to the support assembly 25, and the sliding through hole of the connecting plate 2712 is penetrated by the light rod 2721.

[0111] The first bolt is in threaded connection with the first threaded hole. The head of the first bolt is located outside the first adjusting groove 261. In addition to being used for forming the first sliding pair with the first adjusting groove 261, the first bolt is also used for locking the mounting frame 211 and the transition assembly 26, so that the mounting frame 211 and the transition assembly 26 cannot slide. The first bolt is also used for unlocking the mounting frame 211 and the transition assembly 26, so that the mounting frame 211 and the transition assembly 26 can slide relatively. The locking force of the first bolt for locking or unlocking the mounting frame 211 and the transition assembly 26 is formed by the friction force of the threaded connection of the first bolt and the first threaded hole and the friction force of the head of the first bolt and the transition assembly 26;

[0112] The third bolt is connected with the third threaded hole, and the head of the third bolt is located outside the third adjusting groove 262. In addition to forming a third sliding pair with the third adjusting groove 262, the third bolt is also used to lock the transition assembly 26 and the support assembly 25, so that the transition assembly 26 and the support assembly 25 cannot slide, and the third bolt is used to unlock the transition assembly 26 and the support assembly 25, so that the transition assembly 26 and the support assembly 25 can slide relative to each other. The locking force of the third bolt for locking or unlocking the transition assembly 26 and the support assembly 25 is formed by the friction of the threaded connection of the third bolt and the third threaded hole, and the friction of the head of the third bolt and the transition assembly 26.

[0113] The specific structure of the linear bearing 2711 is known to those skilled in the art, and will not be described here. The two connecting plates 2712 are respectively sleeved on the light rod 2721 through sliding through holes, so that the two connecting plates 2712 can slide relative to the light rod 2721. The light rod 2721 is sleeved with two positioning blocks 2722 at both ends, so that the light rod 2721 forms a gap or a distance with the bottom surface of any one of the positioning blocks 2722, and the light rod 2721 located between the two positioning blocks 2722 forms a sliding path for the connecting plate 2712 and the linear bearing 2711. The linear bearing 2711 is detachably connected with the support plate 252 of the aforementioned support assembly 25 in the direction along the Z-axis of the three-dimensional coordinate system, for example, a fourth threaded hole is provided on the support plate 252 of the aforementioned support assembly 25, and the linear bearing 2711 is connected to the fourth threaded hole through a bolt.

[0114] It should be understood that in other embodiments, the first positioning component D1 can also be provided as a positioning pin, and the first connecting hole 212 is provided as a positioning through hole. The positioning pin is inserted into the first adjusting groove 261 and the positioning through hole, respectively. In order to realize the functions of locking and unlocking the mounting frame 211 and the transition assembly 26, a locking component such as a snap spring or a snap pin needs to be provided on the positioning pin, and a corresponding clamping groove or positioning hole structure needs to be provided on the positioning pin.

[0115] It should be understood that in other embodiments, the third positioning component D3 can also be provided as a positioning pin, and the third connecting hole 251 is provided as a positioning through hole, and the positioning pin is inserted into the third adjusting and positioning through hole respectively; similarly, in order to realize the function of locking and unlocking the transition assembly 26 and the support assembly 25, a locking component such as a snap spring or a snap pin needs to be provided on the positioning pin, and a corresponding snap groove or positioning hole structure needs to be provided on the positioning pin.

[0116] It should be understood that in other embodiments, a common slider and slide rail can also be used instead of the aforementioned linear bearing 2711 and the light lever 2721.

[0117] Further, in the scheme in which the aforementioned sliding part 271 includes the linear bearing 2711 and the two connecting plates 2712, in order to avoid the force applied by the swing arm mechanism 3 to the clutch and brake pedal assembly being transmitted to the sliding part 271 when the clutch and brake pedal assembly is actually detected, so that the sliding part 271 slides relative to the light lever 2721, and the light lever 2721 relative to the two positioning blocks 2722 is displaced, the following scheme is preferably used to lock the sliding part 271 and the light lever 2721, and the following scheme is preferably used to lock the light lever 2721 relative to the two positioning blocks 2722.

[0118] Referring to Figure 11 , Figure 12 , Figure 14 or Figure 15 , the connecting plate 2712 is provided with a first deformation part 2713 and a first connecting part 2714, a first deformation gap is formed between the first deformation part 2713 and the first connecting part 2714, the first deformation gap is communicated with the sliding through hole, and the first deformation part 2713 and the first connecting part 2714 are connected by a first adjusting bolt, wherein the first deformation part 2713 has a first initial state without deformation and a first clamping state with deformation, and the first adjusting bolt is used to control the first deformation part 2713 to switch between the first initial state and the first clamping state.

[0119] The positioning block 2722 is provided with a second deformation part 2723 and a second connecting part 2724, a second deformation gap is formed between the second deformation part 2723 and the second connecting part 2724, the second deformation gap is communicated with the mounting through hole, and the second deformation part 2723 and the second connecting part 2724 are connected by a second adjusting bolt, wherein the second deformation part 2723 has a second initial state without deformation and a second clamping state with deformation, and the second adjusting bolt is used to control the second deformation part 2723 to switch between the second initial state and the second clamping state.

[0120] Wherein, when the first deformation part 2713 and the first connecting part 2714 are in the first initial state, the first deformation gap is not reduced, and the diameter of the sliding through hole matches the diameter of the light rod 2721, at this time the connecting plate 2712 can be sleeved on the light rod 2721, and the connecting plate 2712 can slide relative to the light rod 2721; when the first deformation part 2713 and the first connecting part 2714 are transformed from the first initial state to the first clamping state, the first deformation part 2713 is deformed in the direction of the first connecting part 2714, causing the first deformation gap to be reduced, and because the first deformation gap is communicated with the sliding through hole, the diameter of the sliding through hole changes from the trend of decreasing to the trend of increasing, causing the friction between the connecting plate 2712 and the light rod 2721 to increase, thereby forming the locking function of the sliding part 271 and the light rod 2721; when it is necessary to adjust the position of the sliding part 271 relative to the guide part 272, the first deformation part 2713 is adjusted from the first clamping state to the first initial state again, so that the first deformation gap increases, thereby the diameter of the guide through hole contacts the trend of decreasing, reducing the friction between the connecting plate 2712 and the light rod 2721.

[0121] The first adjusting screw is used to control the switching of the first deformation part 2713 between the first initial state and the first clamping state; specifically, in the first deformation part 2713 and the first connecting part 2714, one of the deformation parts is processed with a threaded through hole, and the other is processed with a matching through hole, and the first adjusting screw is connected to the threaded through hole through the matching through hole;

[0122] When it is necessary to adjust the first deformation part 2713 to the first initial state, the first adjusting screw is loosened, and at least the head part of the first adjusting screw is spaced from the surface of the deformation part provided with the matching through hole, so that the first deformation part 2713 forms the first initial state;

[0123] Correspondingly, when it is necessary to adjust the first deformation part 2713 to the first clamping state, the first adjusting screw is tightened, and at least the first deformation part 2713 is deformed in the direction of the first connecting part 2714 under the clamping force of the screw, so that the first deformation part 2713 forms the first clamping state.

[0124] It should be understood that the technical scheme and technical principle of the second deformation part 2723 forming the second initial state are the same as those of the first deformation part 2713 forming the first initial state, which will not be described here; correspondingly, the technical scheme and technical principle of the second deformation part 2723 forming the second clamping state are the same as those of the first deformation part 2713 forming the first clamping state, and the rest will not be described here.

[0125] Further, referring to Figures 6 to 8The detection device for the clutch brake pedal assembly of the embodiment further comprises a support frame 304, a mounting plate 305, a driving assembly 306 and a transmission assembly 307.

[0126] The two plate surfaces of the mounting plate 305 are a first plate surface 3051 and a second plate surface 3052, respectively, which are parallel to the XY plane of the three-dimensional coordinate system.

[0127] The support frame 304 extends along the Z-axis direction of the three-dimensional coordinate system, and the two ends of the support frame 304 are a top end and a bottom end, respectively. The bottom end is detachably or fixedly arranged on the first plate surface 3051, and the top end is provided with the transmission shaft 301.

[0128] The input end of the transmission assembly 307 is coaxially connected with the output end of the driving assembly 306, and the output end of the transmission assembly 307 is coaxially connected with the transmission shaft 301.

[0129] The driving assembly 306 is used to provide kinetic energy, and the transmission assembly 307 receives the kinetic energy of the driving assembly 306 and transmits the kinetic energy to the transmission shaft 301, so that the transmission shaft 301 rotates; the kinetic energy of the driving assembly 306 includes forward kinetic energy and reverse kinetic energy, so that the transmission shaft 301 can rotate in the clockwise direction and the counterclockwise direction;

[0130] The support frame 304 is used to support the transmission shaft 301 at a predetermined height, so that the transmission shaft 301 is at the same height as the hinge shaft of the pedal arm of the clutch brake pedal assembly mounted on the support frame mechanism 2.

[0131] The mounting plate 305 is used to mount the support frame 304 and the driving assembly 306, and the mounting plate 305 and the support frame 304 are used together to mount the transmission assembly 307.

[0132] Further, referring to Figure 8 The transmission assembly 307 of the detection device for the clutch brake pedal assembly of the embodiment comprises a first sprocket 3071, a second sprocket 3072 and a chain 3073.

[0133] The first sprocket 3071 is coaxially arranged on the transmission shaft 301, the second sprocket 3072 is coaxially arranged on the output end of the driving assembly 306, the chain 3073 is configured in a ring shape, and the chain 3073 is sleeved on the first sprocket 3071 and the second sprocket 3072, respectively. At the top end of the support frame 304, the transmission gap of the chain 3073 is clamped by the chain teeth of the first sprocket 3071, and at the bottom end of the support frame 304, the transmission gap of the chain 3073 is clamped by the chain teeth of the second sprocket 3072.

[0134] The transmission assembly 307 further comprises a tensioning sprocket 3074.

[0135] The tensioning sprocket 3074 is arranged on the second plate surface 3052, and an axis of the tensioning sprocket 3074 is parallel to an axis of the output end of the driving assembly 306. The tensioning sprocket 3074 is located outside the annular contour of the chain 3073, and the transmission gap of the chain 3073 is clamped by the sprocket teeth of the tensioning sprocket 3074.

[0136] The driving assembly 306 and the transmission shaft 301 are relatively far apart, and the driving assembly 306 outputs kinetic energy coaxially to the second sprocket 3072, so that the second sprocket 3072 rotates. The second sprocket 3072 drives the chain 3073 and the first sprocket 3071, so that the chain 3073 and the first sprocket 3071 rotate. Thus, the first sprocket 3071 drives the coaxially arranged transmission shaft 301 to rotate.

[0137] In order to avoid the chain 3073 from being disengaged from the sprocket teeth of the first sprocket 3071 and the second sprocket 3072, the tensioning sprocket 3074 is used to change the shape of the chain 3073 arranged on the first sprocket 3071 and the second sprocket 3072, so that the first sprocket 3071 and the second sprocket 3072 are tightly clamped into the transmission gap of the chain 3073.

[0138] Further, referring to Figure 1 Or Figure 5 The detection device for the clutch brake pedal assembly of the embodiment is provided with a plurality of quick clamps 6 on the mounting frame 211.

[0139] The mounting frame 211 has a top and a bottom, at least two quick clamps 6 are arranged on the top, and at least one quick clamp 6 is arranged on the bottom. The clamping direction of any quick clamp 6 relative to the mounting frame 211 is limited along the Y-axis direction of the three-dimensional coordinate system.

[0140] The structure of the quick clamp 6 is known to those skilled in the art and is not described here.

[0141] The connection direction of the quick clamp 6 and the mounting frame 211 is preferably a detachable connection method, which is convenient for replacement when the quick clamp 6 or the mounting frame 211 fails. The detachable connection method of the two includes but is not limited to bolt connection or positioning pin connection.

[0142] According to the model (especially the weight and size) of the clutch brake pedal assembly installed on the support mechanism 2, different models of quick clamps 6 can be selected; in the same support mechanism 2, the number of quick clamps 6 can be configured to be 3 or 4 or more; for example, at least two quick clamps 6 are arranged on the top of the mounting frame 211, on the one hand, the top of the mounting frame 211 matches the operating height of the worker, which can facilitate the worker to operate the quick clamps 6, so that the worker operates at least two quick clamps 6 for a relatively short time, which is beneficial to improve the clamping efficiency, on the other hand, the number of quick clamps 6 is more than two, which is beneficial to improve the installation firmness of the clutch brake pedal assembly relative to the support mechanism 2; for another example, at least one quick clamp 6 is arranged on the bottom of the mounting frame 211, since the bottom of the mounting frame 211 does not match the operating height of the worker, the bottom of the mounting frame 211 is below the operating height of the worker, so the worker needs to bend down or squat to operate the quick clamp 6 on the bottom of the mounting frame 211, therefore, compared with the arrangement of at least two quick clamps 6 on the top, arranging at least one quick clamp 6 on the bottom can relatively reduce the operating time of the worker, thereby reducing the fatigue of the worker.

[0143] Further, referring to Figure 6 , Figure 9 or Figure 10 , the detection device for the clutch brake pedal assembly of the embodiment further comprises a cabinet 7 and a bottom plate 8;

[0144] The cabinet 7 is arranged as a semi-enclosed structure with a flared portion 701 on one side, and the inner cavity of the cabinet 7 is communicated with the flared portion 701;

[0145] The bottom plate 8 is arranged in the inner cavity, and the bottom plate 8 is provided with a first channel 801 and a second channel 802, which are respectively used for penetrating the support frame 304 and the chain 3073 of one of the swing arm mechanisms 3, wherein the bottom plate 8 is parallel to the XY plane of the three-dimensional coordinate system, and the inner cavity is divided into an upper chamber and a lower chamber along the direction of the Z axis of the three-dimensional coordinate system, and the first channel 801 and the second channel 802 are respectively communicated with the upper chamber and the lower chamber;

[0146] The mounting plate 305 is arranged in the lower chamber, the first sprocket 3071 is located in the upper chamber, and the second sprocket 3072 and the tension sprocket 3074 are located in the lower chamber;

[0147] The drive assembly 306 is located in the lower chamber, and the drive assembly 306 comprises a motor 3061 and a speed reducer 3062, the motor shaft of the motor 3061 is coaxially connected with the input end of the speed reducer 3062, the output end of the speed reducer 3062 is coaxially connected with the second sprocket 3072, and the motor 3061 is installed on the mounting plate 305 through the speed reducer 3062.

[0148] The cabinet 7 is arranged to place the support mechanism 2 and the swing arm mechanism 3 in the safety area, and the inner cavity of the cabinet 7 is the safety area. The detection device for the clutch brake pedal assembly in the embodiment can be arranged in the area of the clutch brake pedal assembly production line, and there are many flowing workers in the area. Therefore, when the detection device for the clutch brake pedal assembly is used to detect the clutch brake pedal assembly, the swing arm mechanism 3 can be isolated from the flowing workers or other objects in at least three directions (three surrounding directions of the semi-enclosing structure) by the cabinet 7, so as to avoid the workers or other objects from entering the working area of the swing arm mechanism 3, and improve the safety.

[0149] It should be understood that an infrared detection device is arranged at the flared portion 701 of the cabinet 7. The infrared detection device is used to scan the flared portion 701 of the cabinet 7. When the limbs of the worker operating the detection device for the clutch brake pedal assembly and the flowing workers intrude into the flared portion 701 of the cabinet 7, the infrared detection device can scan the intruding limbs to generate an interrupting electrical signal, and send the interrupting electrical signal to the control mechanism 1. Therefore, the control mechanism 1 can stop the movement of the swing arm mechanism 3 according to the interrupting electrical signal, so as to avoid the limbs of the workers from being injured by the swing arm mechanism 3, and improve the safety of the detection device for the clutch brake pedal assembly.

[0150] It should be understood that a starting mechanism is arranged on the cabinet 7 and is operated by the hands of the worker. The starting mechanism is electrically connected with the control mechanism 1. The starting mechanism generates a starting electrical signal when the hands of the worker operate the starting mechanism. In other words, if the worker operates the starting mechanism by using only one hand, the starting mechanism will not generate the starting electrical signal. The control mechanism 1 starts the swing arm mechanism 3 and other mechanisms that can move only when the control mechanism 1 receives the starting electrical signal. Therefore, the safety of the detection device for the clutch brake pedal assembly is improved.

[0151] In the embodiment, the bottom plate 8 is arranged in the cabinet 7. The main function of the bottom plate 8 is to support the support mechanism 2 and the swing arm mechanism 3. The bottom plate 8 divides the inner cavity of the cabinet 7 into an upper chamber and a lower chamber. Therefore, the swing arm mechanism 3 can be arranged in the cabinet 7 along the Z-axis direction of the three-dimensional coordinate system, that is, part of the swing arm mechanism 3 (including the swing arm 302 and the pressure sensor 5 arranged on the swing arm 302) can be arranged in the upper chamber, and the other part of the swing arm mechanism 3 (including the driving mechanism) can be arranged in the lower chamber. Therefore, the space occupied by the cabinet 7 is reduced.

[0152] The first passage 801 and the second passage 802 are arranged on the bottom plate 8, which makes the support frame 304 and the chain 3073 of one of the swing arm mechanisms 3 penetrate the first passage 801, and makes the support frame 304 and the chain 3073 of the other of the swing arm mechanisms 3 penetrate the second passage 802, so that the kinetic energy of the driving mechanism in the lower chamber can be transmitted to the transmission shaft 301 in the upper chamber through the transmission mechanism.

[0153] The mounting plate 305 is arranged in the lower chamber. Since the bracket mechanism 2 is arranged in the upper chamber, the surface of the bottom plate 8 for mounting the bracket mechanism 2 is occupied by the bracket mechanism 2, so that the connection position of the mounting plate 305 and the bottom plate 8 is affected by the bracket mechanism 2, and the position or space in which the mounting plate 305 and the bottom plate 8 can be connected is small. Therefore, the mounting plate 305 is arranged in the lower chamber, so that the mounting plate 305 has a relatively larger connection position or space relative to the bottom plate 8, which is beneficial to dismounting the swing arm mechanism 3 and the bottom plate 8.

[0154] The driving assembly 306 is arranged in the lower chamber. The driving assembly 306 preferably includes a motor 3061 and a speed reducer 3062. The motor 3061 and the speed reducer 3062 have relatively large volumes. If the motor 3061 and the speed reducer 3062 are arranged in the upper chamber, the space occupied by the cabinet 7 will certainly be increased due to the space already occupied by the bracket mechanism 2. Therefore, the motor 3061 and the speed reducer 3062 are arranged in the lower chamber, so that they are not affected by the space already occupied by the bracket mechanism 2, which is beneficial to reducing the space occupied by the cabinet 7.

[0155] Further, referring to Figure 9 or Figure 12 The detection device for the clutch brake pedal assembly of the embodiment further includes a first linear reciprocating driving mechanism 9 and a first sliding mechanism 10.

[0156] The first sliding mechanism 10 includes a sliding block 1001 and a sliding rail 1002. The sliding block 1001 and the sliding rail 1002 form a sliding pair. The sliding block 1001 and the sliding rail 1002 are configured as a non-separable connection structure along a direction parallel to the Z-axis of the three-dimensional coordinate system. The sliding direction of the sliding pair is parallel to the X-axis of the three-dimensional coordinate system.

[0157] The sliding rail 1002 is arranged on the bottom plate 8, and the mounting plate 305 is arranged on the sliding block 1001.

[0158] The first linear reciprocating driving mechanism 9 is used to drive the mounting plate 305 to make linear reciprocating motion. The path of the linear reciprocating motion of the mounting plate 305 is parallel to the X-axis of the three-dimensional coordinate system.

[0159] The skilled in the art should know that in reality, there are many types of clutch brake pedal assembly, the positions of clutch pedal, clutch pedal arm, brake pedal and brake pedal arm of different types of clutch brake pedal assembly can be configured as the same position or different position, due to the different extension directions of clutch pedal arm and brake pedal arm, and / or due to the different distances between clutch pedal arm and brake pedal arm; in the embodiment, when different types of clutch brake pedal assembly are clamped on the support mechanism 2, it can cause that the clutch pedal cannot contact the pressure sensor 5 of the swing arm mechanism 3 on the corresponding side thereof, and / or the brake pedal cannot contact the pressure sensor 5 of the swing arm mechanism 3 on the corresponding side thereof, at this time, it is necessary to adjust the position of the clutch pedal relative to the pressure sensor 5 of the swing arm mechanism 3 on the corresponding side thereof, and / or it is necessary to adjust the position of the brake pedal relative to the pressure sensor of the swing arm mechanism 3 on the corresponding side thereof.

[0160] In the embodiment, when facing the technical problem that the clutch pedal cannot contact the pressure sensor 5 of the swing arm mechanism 3 on the corresponding side thereof, and / or the brake pedal cannot contact the pressure sensor 5 of the swing arm mechanism 3 on the corresponding side thereof, the first linear reciprocating drive mechanism 9 drives the mounting plate 305, the movement path of the mounting plate 305 is limited to a linear reciprocating path by the first sliding mechanism 10 and the first linear reciprocating drive mechanism 9, so that the support frame 304, the drive assembly 306 and the transmission assembly 307 arranged on the mounting plate 305 make linear reciprocating motion respectively with the mounting plate 305, causing the transmission shaft 301, the swing arm 302 and the pressure sensor 5 arranged on the support frame 304 to make linear reciprocating motion respectively with the mounting plate 305, the pressure sensor 5 on the swing arm 302 can make the action of approaching the support mechanism 2 or the action of moving away from the support mechanism 2, so that the pressure sensor 5 on the swing arm 302 can contact the brake pedal or clutch pedal of the clutch brake pedal assembly arranged on the support mechanism 2.

[0161] It should be understood that different types of clutch brake pedal assembly have different volumes, and it is possible that at least one type of clutch brake pedal assembly cannot be installed in the mounting frame 211; for this case, a plurality of types of mounting frames 211 can be provided, and the mounting frame 211 is replaced to match different types of clutch brake pedal assembly.

[0162] It should be understood that the hinge shaft of the pedal arm of different models of clutch brake pedal assemblies is different, for example, the hinge shaft of the pedal arm of a part of the clutch brake pedal assemblies is close to or far away from the axis of the transmission shaft 301 when the clutch brake pedal assembly is installed on the support mechanism 2, forming the case of the axis of the hinge shaft being offset from the axis of the transmission shaft 301. In the case of a small offset, the laser positioner, the first adjusting structure 22, the second adjusting structure 23 and the third adjusting structure 24 can be used for adjustment, so that the axis of the hinge shaft is adjusted to coincide with the axis of the transmission shaft 301. However, in the case of a large offset, even if the laser positioner, the first adjusting structure 22, the second adjusting structure 23 and the third adjusting structure 24 are used for adjustment, the axis of the hinge shaft may not coincide with the axis of the transmission shaft 301. In the case of the axis of the hinge shaft not coinciding with the axis of the transmission shaft 301, the installation frame 211 with different thicknesses or the support mechanism 2 with different positioning positions can be replaced, and the laser positioner, the first adjusting structure 22, the second adjusting structure 23 and the third adjusting structure 24 are used for adjustment again, so that the problem can be solved.

[0163] The swing arm 302 is provided with an extension plate 308, and the extension plate 308 is provided with a pressure sensor 5. The extension plate 308 and the swing arm are configured as a sliding pair, and the sliding direction of the sliding pair is along the extension direction of the swing arm. The extension plate 308 is locked and unlocked relative to the swing arm by a bolt. When the extension plate 308 is in the locked state relative to the swing arm 302, the extension plate 308 cannot slide relative to the swing arm 302. Conversely, when the extension plate 308 is in the unlocked state relative to the swing arm, the extension plate 308 can slide relative to the swing arm 302.

[0164] It should be understood that the first linear reciprocating drive mechanism 9 can adopt the structure of a linear motor or a gas cylinder in the prior art.

[0165] It should be understood that the specific structure of the slider 1001 and the slide rail 1002 is a mechanism known to those skilled in the art, which will not be described here; in this embodiment, along the direction parallel to the Z axis of the three-dimensional coordinate system, the slider 1001 and the slide rail 1002 are configured as a non-detachable connection structure, that is, the Z axis direction is the vertical direction, the slide rail 1002 is fixedly arranged on the bottom plate 8, and the slider 1001 cannot be separated from the slide rail 1002 along the vertical direction and under the action of its own gravity; correspondingly, along the length direction of the slide rail 1002, the two side surfaces of the slide rail 1002 are respectively provided with recessed sliding channels, and the slider 1001 is provided with clamping block structures that can be inserted into the sliding channels and slide in the sliding channels, which makes the slider 1001 form a structure that cannot be separated from the slide rail 1002 in the vertical direction; or, along the length direction of the slide rail 1002, the two side surfaces of the slide rail 1002 are respectively provided with protruding sliding support parts, and the slider 1001 is provided with sliding recessed parts that can be inserted by the sliding support parts, and the sliding support parts can slide in the sliding recessed parts, which makes the slider 1001 form a structure that cannot be separated from the slide rail 1002 in the vertical direction.

[0166] Further, referring to Figure 1 、 Figures 11 to 13 、 Figure 18 The detection device for the clutch brake pedal assembly of the embodiment further comprises a rotating mechanism 11 and a locking cylinder 12.

[0167] The rotating mechanism 11 comprises a turntable 1101, a thrust bearing 1102, a thrust bearing seat 1103, a bearing 1104, a bearing seat 1105, a gear 1106, a rack 1107 and a second linear reciprocating driving mechanism 13.

[0168] The turntable 1101 is used for mounting a positioning block 2722.

[0169] The bearing seat 1105 forms a first rotation pair relative to the bottom plate 8 through the bearing 1104, the thrust bearing 1102 is sleeved through the thrust bearing 1102 to form a second rotation pair relative to the bottom plate 8, and the axis of the thrust bearing seat 1103 is coaxial with the axis of the bearing seat 1105.

[0170] The turntable 1101 is detachably arranged in the thrust bearing seat 1103, and the axis of the turntable 1101 is coaxial with the axis of the thrust bearing seat 1103.

[0171] The gear 1106 is sleeved on the thrust bearing seat 1103, the movable path of the rack 1107 is limited to a linear reciprocating path by the second linear reciprocating driving mechanism 13, and the rack 1107 is engaged with the gear 1106.

[0172] The bottom plate 8 is provided with mounting through holes (not shown in the figure) respectively communicating with the upper chamber and the lower chamber, and the rotating disc 1101 is provided with a locking through hole 1108, wherein, along the direction from the lower chamber to the upper chamber, the locking through hole 1108 is convergent, and the axis of the mounting through hole and the axis of the locking through hole 1108 are coaxial;

[0173] The locking cylinder 12 comprises a cylinder body 121 and a piston 122, the cylinder body 121 is inserted into and arranged in the mounting through hole, when the piston 122 is inserted into the locking through hole 1108, the rotating disc 1101 is in a locked state relative to the bottom plate 8, and when the piston 122 is separated from the locking through hole 1108, the rotating disc 1101 is in a movable state relative to the bottom plate 8.

[0174] As mentioned in the foregoing, the bracket mechanism 2 and the swing arm mechanism 3 are arranged in the cabinet 7, which makes the clutch brake pedal assembly as a whole be accommodated in the cabinet 7 when the clutch brake pedal assembly is arranged on the bracket mechanism 2; from the perspective of the worker who operates the detection device for the clutch brake pedal assembly in the embodiment, the pedal arm and the pedal of the clutch brake pedal assembly in the cabinet 7 are located on the front side (the third quadrant and the fourth quadrant of the three-dimensional coordinate system) of the bracket mechanism 2 and face the flared portion 701 of the cabinet 7, so that the worker can directly contact and observe the pedal arm and the pedal, while the clutch master cylinder, the clutch switch, the brake light switch and other units of the clutch brake pedal assembly in the cabinet 7 are located on the back side (the first quadrant and the second quadrant of the three-dimensional coordinate system) of the bracket mechanism 2 and face away from the flared portion 701 of the cabinet 7, so that the worker cannot directly operate the clutch master cylinder, the clutch switch, the brake light switch and other units, and therefore, the worker has to go around to the back side of the bracket mechanism 2 to operate the clutch master cylinder, the clutch switch, the brake light switch and other units, but the back side of the bracket mechanism 2 is blocked by one side of the cabinet 7, which causes the worker to be inconvenient to operate the clutch master cylinder, the clutch switch, the brake light switch and other units in the cabinet 7, and makes the operation efficiency of the detection device for the clutch brake pedal assembly in the foregoing scheme low.

[0175] In this embodiment, the rotating mechanism 11 is arranged at the bottom of the support mechanism 2 and located between the support mechanism 2 and the bottom plate 8. When the staff needs to operate the clutch master cylinder, the clutch switch, the brake light switch and other units, the staff can rotate the support mechanism 2 through the rotating mechanism 11, so that the front surface of the support mechanism 2 changes from facing the flared portion 701 of the cabinet 7 to facing away from the flared portion 701 of the cabinet 7, and correspondingly, the back surface of the support mechanism 2 changes from facing away from the flared portion 701 of the cabinet 7 to facing the flared portion 701 of the cabinet 7. Therefore, the clutch brake pedal assembly arranged on the support mechanism 2 rotates with the support mechanism 2, so that the pedal and the pedal arm change from facing the flared portion 701 of the cabinet 7 to facing away from the flared portion 701 of the cabinet 7, and correspondingly, the clutch master cylinder, the clutch switch, the brake light switch and other units change from facing away from the flared portion 701 of the cabinet 7 to facing the flared portion 701 of the cabinet 7. Therefore, the time for the staff to operate the clutch master cylinder, the clutch switch, the brake light switch and other units is reduced, and the operation efficiency of the detection device for the clutch brake pedal assembly in this embodiment is improved.

[0176] Since the rotating disc 1101 is arranged on the thrust bearing seat 1103, the thrust bearing seat 1103 is arranged on the bottom plate 8 through the thrust bearing 1102, and the support mechanism 2 is installed on the rotating disc 1101 through the positioning block 2722. Before the rotating disc 1101 is locked relative to the bottom plate 8, and when the pressure sensor 5 of the swing arm mechanism 3 applies a force to the pedal of the clutch brake pedal assembly, the rotating disc 1101 and the support mechanism 2 receive the force from the swing arm 302 through the clutch brake pedal assembly, and the rotating disc 1101 and the support mechanism 2 may rotate relative to the bottom plate 8, thereby affecting the detection accuracy.

[0177] In this embodiment, the locking through hole 1108 is arranged on the rotating disc 1101, and the locking cylinder 12 is arranged on the bottom plate 8. The piston 122 part of the locking cylinder 12 is inserted into the locking through hole 1108, so that the rotating disc 1101 is locked relative to the bottom plate 8 and cannot rotate. Conversely, the piston 122 part of the locking cylinder 12 is separated from the locking through hole 1108, so that the rotating disc 1101 can rotate relative to the bottom plate 8. Before detecting the clutch brake pedal assembly, as long as the rotating disc 1101 is adjusted to be locked relative to the bottom plate 8 through the locking cylinder 12 and the locking through hole 1108, the above-mentioned situation that the rotating disc 1101 and the support mechanism 2 may rotate relative to the bottom plate 8 can be avoided, thereby avoiding affecting the detection accuracy.

[0178] It should be understood that the locking through hole 1108 is configured to be convergent along the direction of the Z axis, and the locking through hole 1108 forms two ports with the rotating disc 1101, wherein the port close to the locking cylinder 12 is a first port, and the port away from the locking cylinder 12 is a second port, and the diameter of the first port is greater than that of the second port, thereby facilitating the insertion of the piston 122 of the locking cylinder 12 into the locking through hole 1108.

[0179] The detection device for the clutch brake pedal assembly in the embodiment is provided with a plurality of universal wheels at the bottom of the cabinet 7, so that the cabinet 7 and the bracket mechanism 2, the swing arm mechanism 3 and the control mechanism 1 and other units arranged in the cabinet 7 can be moved through the universal wheels; in actual use, the detection device for the clutch brake pedal assembly can be conveniently transported to the production line, the assembly line or the warehouse and other scenes through the universal wheels.

[0180] The detection device for the clutch brake pedal assembly in the embodiment is further provided with a proximity switch (not shown in the figure), which is electrically connected with the control mechanism 1, and is used to judge the position of the pedal arm. The position electric signal generated by the proximity switch and the angle electric signal formed by the angle encoder 4 are respectively fed back to the control mechanism 1. The control mechanism 1 obtains the position information of the pedal arm according to the position electric signal, and obtains the angle information of the rotation of the pedal arm according to the angle electric signal. The control mechanism 1 further obtains the current / voltage data of the motor 3061, and compares the angle information and the position information with the preset reference data (including the designed current / voltage data, angle data and position data, etc.) respectively, on the one hand, whether the currently detected clutch brake pedal assembly is qualified can be obtained, on the other hand, the unqualified clutch brake pedal assembly can be adjusted from the data point of view, which is beneficial to improve the product stability of the clutch brake pedal assembly, and is beneficial to improve the product consistency of the clutch brake pedal assembly in the production process; in addition, the current / voltage data, angle information and position information obtained by the control mechanism 1 are stored in the local or remote server as product traceability data, which is convenient for traceability after the clutch brake pedal assembly is put into use.
