Description

Technical Field

[0001] This application relates to the field of automotive testing technology, specifically to a testing device that simulates driver suitability. Background Technology

[0002] Driving suitability refers to a driver's ability to perform driving tasks flawlessly and without errors, as well as their potential to perform driving duties after driver training. Many external factors influence driving suitability, such as the light transmittance of the windshield, the height of the driver's seat, and the size of the steering wheel. In other words, the driver's comfort during driving will have a certain impact on driving suitability.

[0003] When a collision occurs, the airbag inside the steering wheel deploys and comes into contact with the driver's face. If the force is too great, it can cause facial injury; if the force is too small, it cannot provide adequate cushioning, thus affecting the driver's comfort. Therefore, the position of the steering wheel relative to the driver is crucial. CN202198603U discloses a driver suitability detection device based on simulated driving. However, this detection device cannot observe the feedback from the impact force generated after the airbag deploys, thus failing to find the optimal position of the steering wheel. Summary of the Invention

[0004] This application provides a detection device for simulating driver's driving suitability, which solves the technical problem in related technologies that the detection device cannot observe the feedback brought about by the impact force generated after the airbag is deployed, thus making it impossible to find the optimal setting position of the steering wheel.

[0005] To achieve the above objectives, the technical solution adopted in this application is as follows:

[0006] This application provides a device for simulating driver suitability testing, comprising: a bracket, a base, a test block, and a release unit; wherein, the base is connected to the bracket, and the base has a first groove and an opening communicating with the first groove; the test block is slidably disposed in the first groove along a first direction, the first direction being the direction in which the test block extends into the first groove; the release unit includes: a release component and a test component, the release component being capable of releasing the test component, the release component being connected to the bracket and spaced apart from the test block; the test component includes: a test rope and multiple test tubes, one end of the test rope being connected to the release component, and the other end being connected to the test block through the opening; multiple test tubes are evenly nested on the test rope at intervals, and the test tubes have a first state and a second state, in the first state, the test tubes are fixedly connected to the test rope, and in the second state, the test tubes are slidable relative to the test rope; the test tubes change from the first state to the second state when a collision occurs.

[0007] According to the above-mentioned technical means, when the simulated driver's driving suitability testing device of this application is set parallel to the steering wheel and with a certain distance between them, when the airbag deploys, the airbag pushes the test block to slide into the chassis. At the same time, the chassis moves the test rope, and the release unit releases the test components simultaneously. Under the action of the moving test block, the test rope is stretched and moves with the test block. When the first test tube contacts and collides with the wall where the chassis opening is located, the test tube changes from the first state to the second state, and thus the test tube remains between the chassis and the release unit. Subsequently, when the second test tube contacts and collides with the first test tube, the second test tube changes from the first state to the second state, and thus the second test tube also remains between the chassis and the release unit. Repeating the same operation, as the test rope moves, the test tubes will be arranged sequentially between the base and the release unit. By observing the number of test tubes, the magnitude of the impact force on the test block caused by the airbag can be fed back. This allows for a more intuitive observation of the impact force generated by the airbag deployment. Then, the steering wheel distance is adjusted, and repeated tests are conducted to find the optimal steering wheel setting position. This ensures that after the airbag deploys, it can cushion the impact while reducing facial injuries and driver pain, providing the driver with a greater sense of comfort and thus improving driving suitability.

[0008] In one possible implementation, the test tube includes: a test tube body, a fixing member, and a state adjustment mechanism. The fixing member is disposed within the test tube body, coaxially arranged with it, and slidably engaged with the test rope. The state adjustment mechanism is disposed within the test tube and includes: a fixing plate, a support plate, a roller, a cylinder, and a diagonal bar. One end of the support plate is connected to the fixing member, and the other end of the support plate is hinged to one end of the fixing plate via a first hinge axis; the axial direction of the first hinge axis is perpendicular to the extension direction of the test rope. The other end of the fixing plate is hinged to the roller via a second hinge axis; the axial direction of the second hinge axis is parallel to the axial direction of the first hinge axis and perpendicular to the extension direction of the test rope; the distance from the first hinge axis to the test rope is less than the distance from the second hinge axis to the test rope. The cylinder is disposed on the fixing member, and a telescopic shaft extends from the cylinder. One end of the diagonal bar is connected to the telescopic shaft, and the other end of the diagonal bar can slide on the wall of the fixing plate away from the test rope to compress the fixing plate to rotate towards the test rope.

[0009] According to the aforementioned technical means, in the first state, the telescopic shaft of the cylinder pushes the inclined bar, which squeezes the roller, causing the roller to come into contact with and squeeze the test rope. At this time, the friction between the test rope and the test tube is relatively large (i.e., there is friction between the test rope and the fixing component, and friction between the test rope and the roller), allowing the test tube to slide along with the test rope. When the first test tube contacts and collides with the wall where the bottom box opening is located, the test tube is limited by the bottom box, the friction between the test rope and the test tube is overcome, and the test rope can move relative to the test tube. This changes the sliding friction between the roller and the test rope to rolling friction, causing the test rope to drive the roller to start rotating. The fixing plate connected to the roller rotates away from the test rope under the centrifugal force of the roller, and the telescopic shaft of the squeezing cylinder retracts. Thus, the roller moves away from the test rope, and the friction between the test rope and the test tube disappears. In this way, the test tube can change from the first state to the second state.

[0010] In one possible implementation, the state adjustment mechanism further includes an elastic element, one end of which is connected to the wall of the fixing plate away from the test rope, and the other end of which is connected to the inner wall of the test tube body. When the test tube is in the second state, the elastic element is in a stretched state.

[0011] In this way, when the roller starts to rotate, it is still rotating away from the test rope under the restoring force of the elastic element, so that the roller can move away from the test rope to ensure that the roller gradually disengages from the test rope. The friction between the test rope and the roller disappears, and thus the friction between the test tube and the roller is reduced.

[0012] In one possible implementation, the state adjustment mechanism includes a first state adjustment mechanism and a second state adjustment mechanism, which are located on opposite sides of the test rope. This ensures that the test rope moves relatively smoothly and avoids the occurrence of bends in the test rope caused by the rollers on one side squeezing it in the first state.

[0013] In one possible implementation, a fixing groove is formed at the end of the fixing plate away from the support plate, and the second hinge shaft is disposed within the fixing groove. The state adjustment mechanism further includes a deceleration unit, which comprises a first gear, a gap gear, a deceleration ring, a deceleration block, a transmission component, and an eccentric assembly. The first gear is rotatably connected to the second hinge shaft and is spaced apart from the roller. The deceleration ring is connected to the first gear, and multiple deceleration grooves are evenly spaced on the circumferential wall of the deceleration ring. The deceleration block is elastically connected within the deceleration grooves. The transmission component is connected to the roller on one side. The eccentric assembly comprises a first part and a second part. The first part is connected to the transmission component, and a deceleration motor is disposed on the second part. A gap gear is disposed on the output shaft of the deceleration motor. When the first part rotates, the gap gear in the second part can intermittently mesh with the first gear, so that the deceleration block is intermittently thrown out to contact the test rope.

[0014] When the friction between the roller and the test rope changes from sliding friction to rolling friction, the frictional force decreases. The test rope accelerates under the action of the test block, causing the second test tube to accelerate and potentially damage the first. To prevent this, the roller drives the transmission component, which in turn rotates the first part of the eccentric component. This causes the gap gear in the second part to intermittently mesh with the first gear. This allows the rotation direction of the reduction motor to be controlled to be opposite to the roller's rotation direction. When the reduction block in the reduction groove is thrown out by centrifugal force, and the gap gear meshes with the first gear, it drives the reduction ring to accelerate. When the gap gear disengages from the first gear, the reduction ring decelerates, causing the reduction block in the reduction groove to intermittently throw out and make contact, thus slowing down the movement of the test rope and protecting the integrity of the test tube.

[0015] In one possible implementation, the transmission components include: a second gear, a rotating shaft, and a transmission gear. The second gear is connected to and coaxially arranged with the roller. The rotating shaft is rotatably mounted on a fixed plate about its axial direction. The transmission gear is connected to the rotating shaft and meshes with the second gear. The first part is connected to the rotating shaft. Thus, when the roller rotates, it drives the second gear to rotate as well, and the second gear drives the transmission gear and the rotating shaft to rotate synchronously. Consequently, under the rotational action of the rotating shaft, the first part rotates synchronously.

[0016] In one possible implementation, the release unit includes a first release unit and a second release unit, located on opposite sides of the test block. This ensures a smooth sliding process of the test block as it slides towards the bottom of the first groove, preventing the test block from shifting to the other side under the action of the release unit on one side.

[0017] In one possible implementation, the release assembly includes a housing, a first motor, and a collecting roller. The housing has a receiving cavity and a cable routing port communicating with the receiving cavity. The first motor is disposed in the receiving cavity. The collecting roller is driven by the first motor, and one end of the test rope is wound around the collecting roller through the cable routing port. In this way, by activating the first motor, the collecting roller can be rotated to retract the test assembly onto the cable routing roller for easy re-testing.

[0018] In one possible implementation, the testing device further includes a base and a second motor, the base being rotatably connected to the support; the second motor is mounted on the base and is used to drive the support to rotate. Thus, when the second motor is activated, it can drive the support to rotate, thereby changing the orientation of the test block connected to the support. This facilitates the testing personnel in assessing the driving suitability of the simulated driver.

[0019] In one possible implementation, the testing device further includes a lifting cylinder with a lifting rod extending from it, the lifting rod being connected to a base. Thus, the height of the base can be adjusted via the lifting cylinder, which in turn adjusts the height of the test block, further facilitating the testing of the simulated driver's suitability.

[0024] The embodiments of this application will be described below with reference to the accompanying drawings and preferred embodiments. Those skilled in the art can easily understand other advantages and effects of this application from the content disclosed in this specification. This application can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this application. It should be understood that the preferred embodiments are only for illustrating this application and are not intended to limit the scope of protection of this application.

[0025] It should be noted that the illustrations provided in the following embodiments are only schematic representations of the basic concept of this application. Therefore, the drawings only show the components related to this application and are not drawn according to the actual number, shape and size of the components in the actual implementation. In the actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0026] Figure 1 This illustration shows a three-dimensional structural diagram of a device for simulating driver aptitude testing according to an embodiment of this application. Figure 1 As shown, the testing device 100 includes: a support 00, a base box 10, a test block 20, and a release unit 30.

[0027] Among them, such as Figure 2 As shown, the base box 10 is connected to the bracket 00. The base box 10 has a first groove 111 and an opening 121 communicating with the first groove 111. The test block 20 is slidably disposed in the first groove 111 along a first direction, which is the direction in which the test block 20 extends into the first groove 111. Figure 2 The Z-axis direction is shown.

[0028] In one possible implementation, such as Figure 2 As shown, the bottom box 10 may include: a box body 11 and a frame 12, the frame 12 being spaced apart from the release unit, and the frame 12 having an opening 121.

[0029] Additionally, the release unit 30 includes a release component 31 and a test component 32. The release component 31 can release the test component 32. The release component 31 is connected to the bracket 00 and is spaced apart from the test block 20. The test component 32 includes a test rope 321 and a plurality of test tubes 322. One end of the test rope 321 is connected to the release component 31, and the other end is connected to the test block 20 through an opening 121. The plurality of test tubes 322 are evenly nested on the test rope 321 at intervals, and the test tubes 322 have a first state and a second state. In the first state, the test tubes 322 are fixedly connected to the test rope 321. In the second state, the test tubes 322 can slide relative to the test rope 321. The test tubes 322 change from the first state to the second state when a collision occurs.

[0030] For example, the test rope can be a metal rope, such as a steel rope, or it can be a non-metallic rope; this application does not limit the type of rope.

[0031] To prevent the test rope 321 from getting stuck between the bottom box 10 and the test block 20, one possible implementation is as follows: Figure 2As shown, the test block 20 has a strip groove 21, and one end of the test rope 321 is connected to the bottom wall of the strip groove 21. The strip groove 21 runs along the first direction (i.e., Figure 2 The test rope 321 extends along the Z-axis direction. In this way, when the test block 20 pulls the test rope 321 to move, the test rope 321 can enter the strip groove 21 to ensure that the test block 20 can slide smoothly into the first groove 111.

[0032] For example, such as Figure 2 As shown, the number of the strip grooves 21 can be six, and the six strip grooves 21 are along the second direction (i.e. Figure 2 The test blocks 20 are evenly spaced along the Y-axis and the release unit 30 can release six test components 32. The test ropes 321 of the six test components 32 are respectively connected to the bottom wall of the six strip grooves 21. In this way, the multiple test ropes 321 can fix the test block 20 and prevent the test block 20 from shaking.

[0033] According to the above technical means, when the simulated driver's driving suitability testing device 100 of this application is set parallel to the steering wheel and with a certain distance between them, when the airbag deploys, the airbag pushes the test block 20 to slide into the base box 10. At the same time, the base box 10 moves the test rope 321, and the release unit 30 releases the test component 32 simultaneously, so that the test rope 321 is stretched under the action of the movement of the test block 20 and moves with the test block 20. When the first test tube 322 contacts and collides with the wall where the opening 121 of the base box 10 is located, the test tube 322 changes from the first state to the second state, so that the test tube 322 remains between the base box 10 and the release unit 30. Afterwards, when the second test tube 322 contacts and collides with the first test tube 322, the second test tube 322 changes from the first state to the second state, so that the second test tube 322 also remains between the base box 10 and the release unit 30. Repeating the same operation, as the test rope 321 moves, multiple test tubes 322 will be arranged sequentially between the base box 10 and the release unit 30. By observing the number of test tubes 322, the magnitude of the impact force on the test block 20 caused by the airbag can be fed back. The impact force generated by the airbag deployment can be observed more intuitively. Then, the steering wheel distance is adjusted and repeated tests are conducted to find the optimal setting position of the steering wheel. This allows the airbag to cushion the impact while reducing facial injuries and driver pain after deployment, thus providing the driver with greater comfort and improving driving suitability.

[0034] Figure 3 A three-dimensional structural schematic diagram of a test tube provided in an embodiment of this application is shown. In some embodiments, such as Figure 2 and Figure 3As shown, each test tube 322 includes: a test tube body 3221 ( Figure 3 (Not shown in the image), fastener 3222 and status adjustment mechanism 3223.

[0035] in, Figure 3 This is a schematic diagram of the internal structure of the test tube body 3221, as shown below. Figure 3 As shown, the fixing member 3222 is disposed inside the test tube body 3221, coaxially disposed with the test tube body 3221, and slidably engaged with the test rope 321. The state adjustment mechanism 3223 is disposed inside the test tube 322. This state adjustment mechanism 3223 includes: a fixing plate 32231, a support plate 32232, a roller 32233, a cylinder 32234, and an inclined bar 32235. One end of the support plate 32232 is connected to the fixing member 3222, and the other end of the support plate 32232 is hinged to one end of the fixing plate 32231 via a first hinge shaft; the axial direction of the first hinge shaft is perpendicular to the extension direction of the test rope 321; the other end of the fixing plate 32231 is hinged to the roller 32233 via a second hinge shaft; the second... The axial direction of the hinge shaft is parallel to the axial direction of the first hinge shaft and perpendicular to the extension direction of the test rope 321; the distance from the first hinge shaft to the test rope 321 is less than the distance from the second hinge shaft to the test rope 321; the cylinder 32234 is mounted on the fixing member 3222, and a telescopic shaft 32236 extends from the cylinder 32234; one end of the inclined bar 32235 is connected to the telescopic shaft 32236, and the other end of the inclined bar 32235 can slide on the wall surface of the fixing plate 32231 away from the test rope 321 to squeeze the fixing plate 32231 to rotate in the direction of the test rope 321.

[0036] According to the above technical means, when in the first state, the telescopic shaft 32236 of the cylinder 32234 pushes the inclined bar 32235, and the inclined bar 32235 squeezes the roller 32233 so that the roller 32233 abuts against and squeezes the test rope 321. In this way, the friction between the test rope 321 and the test tube 322 is large (that is, there is friction between the test rope 321 and the fixing member 3222 and friction between the test rope 321 and the roller 32233), and the test tube 322 can slide along with the test rope 321. When the first test tube 322 contacts and collides with the wall surface where the opening 121 of the base box 10 is located, the test tube 322 is limited by the base box 10, the friction between the test rope 321 and the test tube 322 is overcome, and the test rope 321 can move relative to the test tube 322. This causes the sliding friction between the roller 32233 and the test rope 321 to change to rolling friction, driving the roller 32233 to start rotating. The fixed plate 32231 connected to the roller 32233 rotates away from the test rope 321 under the centrifugal force of the roller 32233. The telescopic shaft 32236 of the compression cylinder 32234 retracts, thus moving the roller 32233 away from the test rope 321, and the friction between the test rope 321 and the test tube 322 disappears. In this way, the test tube 322 can change from the first state to the second state.

[0037] To ensure that the roller 32233 can gradually detach from the test rope 321, in one possible implementation, the state adjustment mechanism 3223 further includes an elastic element 32237. One end of the elastic element 32237 is connected to the wall surface of the fixing plate 32231 away from the test rope 321, and the other end of the elastic element 32237 is connected to the inner wall surface of the test tube body 3221. When the test tube 322 is in the second state, the elastic element 32237 is in a stretched state.

[0038] For example, the elastic element 32237 can be a tension spring, or it can be a compression spring; this application does not limit this to any particular type.

[0039] In this way, when the roller 32233 starts to rotate, it is still rotating away from the test rope 321 under the reset force of the elastic element 32237, so that the roller 32233 can move away from the test rope 321, ensuring that the roller 32233 gradually disengages from the test rope 321 and the friction between the test rope 321 and the test tube 322 disappears.

[0040] In other embodiments, the test tube 322 may include a clamping mechanism and a touch switch. The touch switch is disposed on the wall surface of the test tube 322 near the base box 10. The clamping mechanism may include a motor and an abutment. The motor can drive the abutment to reciprocate so that the abutment abuts against the test rope 321 or is spaced apart from the test rope 321. The touch switch is electrically connected to the motor. When the touch switch of the test tube 322 collides with the base box 10 (or other test tubes 322), the touch switch sends a signal to the motor, and the motor controls the abutment to move so that the abutment is spaced apart from the test rope 321. In this way, the test tube 322 can change from a first state to a second state.

[0041] To ensure the test rope 321 remains relatively stable during movement, in some embodiments, such as... Figure 3 As shown, the state adjustment mechanism 3223 includes a first state adjustment mechanism and a second state adjustment mechanism. The specific structures of the first and second adjustment mechanisms are described above and will not be repeated here. The first and second state adjustment mechanisms 3223 are located on opposite sides of the test rope 321.

[0042] This ensures that the test rope 321 moves relatively smoothly, avoiding the situation where the roller 32233 on one side squeezes the test rope 321 in the first state, causing the test rope 321 to have a bend.

[0043] It is understandable that when the friction between the roller 32233 and the test rope 321 changes from sliding friction to rolling friction, the friction will decrease, and the test rope 321 will accelerate under the action of the test block 20. As a result, the second test tube 322 will accelerate to contact the first test tube 322, which may easily lead to damage to the test tube 322.

[0044] To avoid this problem, in some embodiments of this application, such as Figure 4As shown, the fixed plate 32231 has a fixed groove at one end away from the support plate 32232, and the second hinge shaft is disposed in the fixed groove; the state adjustment mechanism 3223 also includes a reduction unit 32238, which includes a first gear 322381, a gap gear 322382, a reduction ring 322383, a reduction block 322384, a transmission component 322385, and an eccentric assembly 322386. The first gear 322381 is rotatably connected to the second hinge shaft and is spaced apart from the roller 32233; the reduction ring 322383 is connected to the first gear 322381, and a plurality of reduction grooves 322383a are evenly spaced on the circumferential wall surface of the reduction ring 322383; it can be understood that the plurality of reduction grooves 32238a are evenly spaced along the circumferential direction of the reduction ring 322383. The deceleration block 322384 is elastically connected within the deceleration groove 322383a; one side of the transmission component 322385 is connected to the roller 32233; the eccentric assembly 322386 includes: a first part 3223861 and a second part 3223862. The first part 3223861 is connected to the transmission component 322385, and a deceleration motor is provided on the second part 3223862. A gap gear 322387 is provided on the output shaft of the deceleration motor. When the first part 3223861 rotates, the gap gear 322382 of the second part 3223862 can intermittently mesh with the first gear 322381, so that the deceleration block 322384 is intermittently thrown out to contact the test rope 321.

[0045] For example, such as Figure 4 As shown, the eccentric component 322386 can be an L-shaped rod, one end of which is connected to the transmission component 322385, and the other end is connected to the first motor.

[0046] In this way, when the sliding friction between the roller 32233 and the test rope 321 changes to rolling friction, the roller 32233 drives the transmission component 322385 to move, and the transmission component 322385 drives the first part 3223861 of the eccentric component 322386 to rotate, so that the gap gear 322382 of the second part 3223862 can intermittently mesh with the first gear 322381. In this way, the rotation direction of the geared motor can be controlled to be opposite to that of the roller 32233; when the deceleration block 322384 in the deceleration groove 322383a is thrown out of the deceleration groove 322383a under the action of centrifugal force; when the intermittent gear 322387 meshes with the first gear 322381, it will drive the deceleration ring 322383 to accelerate; when the intermittent gear 322382 disengages from the first gear 322381, the deceleration ring 322383 will decelerate, thereby causing the deceleration block 322384 in the deceleration groove 322383a to be thrown out intermittently and come into contact with the test rope 321, so as to decelerate the movement of the test rope 321, thereby protecting the integrity of the test tube 322.

[0047] In one possible implementation, the transmission component 322385 includes: a second gear 3223851, a rotating shaft 3223852, and a transmission gear 3223853. The second gear 3223851 is connected to and coaxially arranged with the roller 32233. The rotating shaft 3223852 is rotatably mounted on the fixed plate 32231 about its axial direction. The transmission gear 3223853 is connected to the rotating shaft 3223852 and meshes with the second gear 3223851. A first part 3223861 is connected to the rotating shaft 3223852. Thus, when the roller 32233 rotates, it drives the second gear 3223851 to rotate as well, and the second gear 3223851 drives the transmission gear 3223853 and the rotating shaft 3223852 to rotate synchronously. Thus, under the rotation of the rotating shaft 3223852, the first part 3223861 rotates synchronously.

[0048] For example, such as Figure 4 As shown, a transition rod 322387 is provided on the side wall of the fixed groove. A rotatable rotating shaft 3223852 is connected inside the transition rod 322387. The two ends of the rotating shaft 3223852 are located on opposite sides of the transition rod 322387. One end is coaxially fixedly connected to a transmission gear 3223853 that meshes with the second gear 3223851, and the other end is fixedly connected to the first part 3223861 of the eccentric assembly 322386.

[0049] Similarly, to ensure smoother sliding of the test block 20, in some embodiments, such as Figure 1 and Figure 2As shown, the release unit 30 includes a first release unit and a second release unit, which are located on opposite sides of the test block 20. This ensures that the test block 20 slides smoothly towards the bottom of the first groove 111, preventing the test block 20 from shifting to the other side under the action of the release unit 30 on one side.

[0050] In some embodiments, the release assembly 31 includes: a housing 311, a first motor, and a collecting roller. The housing 311 has a receiving cavity and a cable routing port 312 communicating with the receiving cavity. The first motor is disposed in the receiving cavity. The collecting roller is drivenly connected to the first motor, and one end of the test rope 321 is wound around the collecting roller through the cable routing port 312.

[0051] In this way, by starting the first motor, the collecting roller can be rotated to recycle the test component 32 onto the wire roller for easy testing next time.

[0052] To facilitate adjustment of the position of the testing device 100 by the tester, in some embodiments, such as Figure 1 As shown, the detection device 100 also includes: a base 40 and a second motor, the base 40 being rotatably connected to the bracket 00; the second motor is mounted on the base 40 and is used to drive the bracket 00 to rotate.

[0053] In this way, when the second motor is started, the second motor can drive the bracket 00 to rotate, thereby changing the orientation of the test block 20 connected to the bracket 00. This makes it convenient for testers to test the driving suitability of the simulated driver.

[0054] Furthermore, in some embodiments, the detection device 100 further includes: a lifting cylinder 50, a lifting rod 51 extending from the lifting cylinder 50, and the lifting rod 51 being connected to the base 40.

[0055] Thus, the height of the base 40 can be adjusted by the lifting cylinder 50, which in turn can adjust the height of the test block 20, further facilitating the testing personnel to detect the driving suitability of the simulated driver.

[0056] The above embodiments are merely preferred embodiments provided to fully illustrate this application, and the scope of protection of this application is not limited thereto. Equivalent substitutions or modifications made by those skilled in the art based on this application are all within the scope of protection of this application.
