Description

Technical Field

[0001] This invention relates to the field of unmanned forklift testing, and more specifically to a performance testing device for unmanned forklifts. Background Technology

[0002] Unmanned forklifts are mainly used in port loading and logistics. They are highly intelligent and unmanned, with high and stable operating efficiency. Unmanned forklifts can travel along a prescribed trajectory and can also adjust their running trajectory and vehicle posture according to real-time road conditions.

[0003] To ensure safe operation, autonomous forklifts are subject to certain performance requirements, such as braking distance, emergency obstacle avoidance, and obstacle passage. Before leaving the factory, autonomous forklifts need to undergo a series of performance tests to ensure they can operate normally.

[0004] Existing tests on the performance of driverless forklifts are mostly conducted in specific locations with rudimentary equipment. These tests do not closely reflect real-world working conditions, resulting in distorted performance indicators for driverless forklifts.

[0005] Therefore, how to provide a performance testing device for unmanned forklifts that can overcome the above-mentioned problems is a problem that urgently needs to be solved by those skilled in the art. Summary of the Invention

[0006] In view of this, the present invention provides a performance testing device for an unmanned forklift.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] A performance testing device for an unmanned forklift, comprising:

[0009] A roadbed plate is horizontally arranged with a wall panel vertically fixed at one end. The surface of the wall panel is perpendicular to the length direction of the roadbed plate. The upper surface of the roadbed plate is provided with two interconnected test road sections, the length directions of both test road section one and test road section two are the same as the length direction of the roadbed plate. A scale line is provided on the upper surface of the roadbed plate along its length direction, and the scale line corresponds to the position of test road section one.

[0010] A single-sided narrowing and obstacle simulation component includes a geared motor, a support shaft, and an obstacle plate. The geared motor is fixed to one side of the roadbed plate. The second test section is located between the first test section and the geared motor. The support shaft is vertically arranged and its lower end is coaxially fixed to the output shaft of the geared motor. The surface of the obstacle plate is vertically arranged. One end of the obstacle plate is fixed to the outer wall of the support shaft, and the other end of the obstacle plate can be arranged inside the second test section.

[0011] A turning test assembly is arranged between test section one and test section two. The turning test assembly includes a telescopic cylinder and a baffle. The telescopic cylinder is horizontally fixed to the upper surface of the roadbed plate. The baffle is vertically arranged and perpendicular to the surface of the wall panel. One end of the baffle is fixed to the telescopic end of the telescopic cylinder. The baffle is arranged between the wall panel and the telescopic cylinder. The unmanned forklift can drive between the wall panel and the baffle.

[0012] As can be seen from the above technical solution, compared with the prior art, the present invention discloses a performance testing device for an unmanned forklift. The present invention designs a road plate and divides it into test section one and test section two. Test section one has a scale line. The unmanned forklift can perform braking distance tests on test section one. The scale line one can accurately measure the braking distance of the unmanned forklift from the start of emergency braking to the stop. By designing a single-sided narrowing and obstacle simulation component, the unmanned forklift travels on test section two. The reduction motor can drive the obstacle plate to swing rapidly and significantly or slightly. The moving unmanned forklift can detect the obstacle plate in front and brake suddenly, or detect the narrowing of the path ahead and change direction. The simulation component can perform emergency obstacle avoidance tests on the unmanned forklift and also test the unmanned forklift's changing direction ability. By designing a turning test component, when the unmanned forklift turns from test section two to test section one, the turning performance between the baffle and the wall plate can be tested by adjusting the distance between the baffle and the wall plate.

[0013] Preferably, the system further includes speed bump simulation components, two of which are sequentially arranged along the width direction of the roadbed plate, each corresponding to the position of the second test section. The roadbed plate has a device cavity on its lower side, and a limiting hole communicating with the device cavity is opened on its upper surface, corresponding to the position of the second test section. Each speed bump simulation component includes a second telescopic cylinder, a stop block, a top plate, and a connecting plate. The second telescopic cylinder is horizontally installed within the device cavity. The stop block is fixed to the telescopic ends of the first and second telescopic cylinders. The moving direction of the stop block is the same as the length direction of the roadbed plate. An inclined surface is provided on the stop block relative to the horizontal direction. The forklift is arranged at an angle, with the vertical line of the angled surface coplanar with the center line of the roadbed plate along its length. A top plate slides through the limiting hole, its lower side slidingly abutting against the angled surface. The length directions of the connecting plates and the top plate are the same as the width direction of the roadbed plate. The upper side of the top plate is hinged to one long side of each of the two connecting plates, with the hinge axis perpendicular to the length direction of the roadbed plate. The other long side of each of the two connecting plates slides against the upper surface of the roadbed plate. The top plate is positioned between the two connecting plates, allowing the wheels of the unmanned forklift to roll against the upper side of the top plate and one side of the connecting plates. The height of the top plate can be reliably adjusted to simulate speed bumps of different heights, thereby testing the obstacle-crossing capability of the unmanned forklift. The design of the connecting plates facilitates the unmanned forklift crossing the top plate.

[0014] Preferably, the length of the top plate is less than the width of the driverless forklift, the two top plates are aligned face-to-face, and the total length of the two top plates is greater than the width of the driverless forklift. The driverless forklift can reliably pass over the top plate.

[0015] Preferably, the unilateral narrowing and obstacle simulation component further includes a support frame, which is fixed to the body of the reduction motor, and the upper end of the support shaft is rotatably connected to the support frame. The support shaft can rotate reliably.

[0016] Preferably, the turning test assembly further includes an optical axis and a limiting block. The optical axis is horizontally arranged with one end fixed to the baffle. The centerline of the optical axis is perpendicular to the surface of the wall panel, and the optical axis is located above the telescopic cylinder. The limiting block is fixed to the road plate and has a through hole one and a through hole two. The optical axis slides through the through hole one, and the telescopic shaft of the telescopic cylinder one passes through the through hole two. The baffle can move back and forth smoothly.

[0017] Preferably, the turning test assembly further includes a protective plate, the surface of which is vertically arranged, and the length direction of the protective plate is the same as that of the roadbed plate. Two protective plates are provided with their ends aligned. The baffle, the first telescopic cylinder, the optical axis, and the limiting block are all located between the two protective plates. The unmanned forklift will not collide with the first telescopic cylinder, the optical axis, or the limiting block.

[0018] Preferably, a second scale line is provided on the upper surface of the roadbed plate along its length. The second scale line is located between the first test section and the second test section, and the end of the baffle away from the telescopic cylinder can be aligned with the second scale line. The distance between the baffle and the wall panel can be precisely adjusted. Attached Figure Description

Detailed Implementation

[0028] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] This invention discloses a performance testing device for an unmanned forklift. The invention designs a road plate 2 and divides the road plate 2 into a test section 1 and a test section 2. A scale line 20 is arranged on the test section 1. The unmanned forklift 1 can perform braking distance testing on the test section 1. The braking distance of the unmanned forklift 1 from the start of emergency braking to the stop can be accurately measured through the scale line 20.

[0030] By designing a single-sided narrowing and obstacle simulation component, the unmanned forklift 1 travels on test section two. When the reduction motor 4 drives the obstacle plate 6 to swing rapidly and significantly, the unmanned forklift 1 can detect the obstacle plate 6 in front and brake suddenly. When only a small part of the obstacle plate 6 enters the inner side of test section two, the test section two at that position narrows on one side. The unmanned forklift 1 can detect the narrowing of the path ahead and change direction to ensure that it can travel normally on test section two. The simulation component can not only conduct emergency obstacle avoidance tests on the unmanned forklift 1, but also test the reversing ability of the unmanned forklift 1.

[0031] By designing a turning test component, the telescopic cylinder 8 can drive the baffle 9 to move. The distance between the baffle 9 and the wall plate 3 can be adjusted. When the unmanned forklift 1 turns from test section 2 to test section 1, the turning performance between the baffle 9 and the wall plate 3 can be tested by adjusting the distance between the baffle 9 and the wall plate 3.

[0032] By designing a speed bump simulation component, the telescopic cylinder 13 pushes the abutment block 14 to move. When the abutment block 14 moves, it drives the top plate 15 to move up and down by relying on its own inclined surface 140, thereby realizing the height adjustment of the top plate 15, thus simulating speed bumps of different heights, and thus testing the obstacle passage ability of the unmanned forklift 1; the design of the connecting plate 16 makes it easy for the unmanned forklift 1 to cross the top plate 15.

[0033] Example

[0034] See appendix Figure 1-6 This is a schematic diagram of the overall and partial structure of one embodiment of the present invention. Specifically, the present invention discloses a performance testing device for an unmanned forklift, used to test the performance of the unmanned forklift 1, mainly testing its obstacle-crossing ability, emergency obstacle avoidance ability, turning ability, and braking distance. The testing device includes:

[0035] The rectangular road plate 2 is horizontally and tightly placed on the ground. The friction coefficient of the upper surface of the road plate 2 is the same as the friction coefficient of the ground where the unmanned forklift 1 actually works.

[0036] A rectangular wall panel 3 is vertically fixed at one end of the roadbed 2. The wall panel 3 is made of lightweight elastic material and has a certain impact resistance. The surface of the wall panel 3 is perpendicular to the length direction of the roadbed 2.

[0037] The upper surface of the road plate 2 is provided with a straight test road section one and a test road section two. The ends of the test road section one and the test road section two near the wall plate 3 are connected to each other. The unmanned forklift 1 can turn from the test road section two onto the test road section one. The length direction of the test road section one and the length direction of the test road section two are the same as the length direction of the road plate 2. The test road section one and the test road section two are wide enough to ensure that the unmanned forklift 1 will not drive off the road plate 2 when turning from the test road section two onto the test road section one.

[0038] A scale line 20 is provided on the upper surface of the roadbed plate 2 along its length. The scale line 20 corresponds to the position of the test section 1. The unmanned forklift 1 can perform no-load or loaded braking distance tests on the test section 1. The braking distance of the unmanned forklift 1 can be measured through the scale line 20. The braking distance test of the unmanned forklift 1 is prior art. After the unmanned forklift 1 reaches a certain speed, it brakes suddenly to a complete stop. The scale line 20 in this application can be used to measure the distance from the position of the vehicle body when the unmanned forklift 1 starts to brake suddenly to the position of the vehicle body after it comes to a complete stop, so as to ensure that the braking distance of the unmanned forklift 1 can be accurately measured.

[0039] The single-sided narrowing and obstacle simulation component includes a geared motor 4, a support shaft 5, and an obstacle plate 6. The geared motor 4 is fixed on one side of the roadbed 2. The second test section is located between the first test section and the geared motor 4. The support shaft 5 is arranged vertically and its lower end is coaxially fixed with the output shaft of the geared motor 4. The obstacle plate 6, made of lightweight material, is arranged vertically. One end of the obstacle plate 6 is fixed to the outer wall of the support shaft 5, and the other end of the obstacle plate 6 can be arranged on the inner side of the second test section.

[0040] The geared motor 4 can drive the obstacle plate 6 to swing. When the unmanned forklift 1 is traveling on the second test section, the geared motor 4 in front of the unmanned forklift 1 can drive the obstacle plate 6 to swing rapidly, so that the end of the obstacle plate 6 away from the support shaft 5 enters the inner side of the second test section, and the surface of the obstacle plate 6 is almost perpendicular to the length direction of the road plate 2. At this time, the emergency obstacle avoidance and braking functions of the unmanned forklift 1 can be measured.

[0041] When only a small portion of the obstacle 6 enters the interior of test section two, the unmanned forklift 1 can still pass through test section two normally. However, at the location of obstacle 6, the passage width of test section two becomes narrower. At this time, the obstacle avoidance and reversing functions of the unmanned forklift 1 can be tested.

[0042] A turning test assembly is arranged between test section one and test section two. The turning test assembly includes a telescopic cylinder 8 and a rectangular baffle 9. The telescopic cylinder 8 is horizontally fixed to the upper surface of the roadbed 2. The baffle 9 is vertically arranged and perpendicular to the surface of the wall panel 3. One end of the baffle 9 is fixed to the telescopic end of the telescopic cylinder 8. The baffle 9 is arranged between the wall panel 3 and the telescopic cylinder 8. The telescopic cylinder 8 can drive the baffle 9 to move. The shortest distance between the baffle 9 and the wall panel 3 can be adjusted. The unmanned forklift 1 can drive between the wall panel 3 and the baffle 9. The shortest distance between the baffle 9 and the wall panel 3 is variable, which can be used to test the turning ability of the unmanned forklift 1.

[0043] With the total length and width of the unmanned forklift 1 remaining constant, the closer the baffle 9 is to the wall panel 3, the better the turning ability of the unmanned forklift 1 is required.

[0044] More specifically, it also includes speed bump simulation components. Two speed bump simulation components are arranged sequentially along the width direction of the roadbed 2, and both speed bump simulation components correspond to the position of the test road section 2.

[0045] The lower side of the road plate 2 is provided with an equipment cavity 21, and the upper surface of the road plate 2 is provided with a limiting hole 22 that communicates with the equipment cavity 21. The limiting hole 22 corresponds to the position of the second test section.

[0046] Each speed bump simulation component includes a telescopic cylinder 13, a stop block 14, a top plate 15, and two connecting plates 16. The telescopic cylinder 13 is horizontally installed in the equipment cavity 21. The stop block 14 is fixed to the telescopic end of the telescopic cylinder 13. The stop block 14 slides and is in close contact with the ground. The moving direction of the stop block 14 is the same as the length direction of the road plate 2. The stop block 14 is provided with an inclined surface 140. The inclined surface 140 is arranged at an angle relative to the horizontal plane. The vertical line of the inclined surface 140 is coplanar with the center line of the road plate 2 in the length direction.

[0047] A top plate 15 is slidably inserted through the limiting hole 22. The lower side of the top plate 15 slides against the inclined surface 140. The lower side of the top plate 15 is a smooth arc shape, which ensures that the top plate 15 can smoothly slide against the inclined surface 140 when the abutment block 14 moves.

[0048] The connecting plate 16 is a rectangular plate. The length direction of the connecting plate 16 and the length direction of the top plate 15 are the same as the width direction of the roadbed 2. The upper side of the top plate 15 is hinged to one long side of each of the two connecting plates 16, and the hinge axis is perpendicular to the length direction of the roadbed 2. The other long side of the two connecting plates 16 can slide against the upper surface of the roadbed 2. The top plate 15 is arranged between the two connecting plates 16, and the wheels of the unmanned forklift 1 can roll against the upper side of the top plate 15 and one side surface of the connecting plate 16. The telescopic cylinder 13 can carry... When the moving abutment block 14 moves, the lower side of the top plate 15 slides relative to the inclined surface 140. Due to the design of the inclined surface 140, the top plate 15 moves up and down by the horizontal movement of the abutment block 14, thereby adjusting the distance between the upper side of the top plate 15 and the upper surface of the road plate 2. Since the connecting plate 16 is hinged to the top plate 15, the connecting plate 16 can provide an inclined surface 140, which helps the unmanned forklift 1 to cross the top plate 15. The height of the top plate 15 is adjustable, which can be used to test the ability of the unmanned forklift 1 to cross obstacles.

[0049] Meanwhile, due to the design of two speed bump simulation components, the two telescopic cylinders 13 can operate independently, and the two top plates 15 can have different heights, which can further detect the posture of the vehicle body and the stability of the vehicle body structure when the unmanned forklift 1 crosses obstacles.

[0050] The length of the top plate 15 is less than the width of the driverless forklift 1. The two top plates 15 are aligned, and the total length of the two top plates 15 is greater than the width of the driverless forklift 1. This design ensures that the driverless forklift 1 can reliably pass over the two top plates 15.

[0051] More specifically, telescopic cylinder 8 and telescopic cylinder 13 are both electric cylinders. Telescopic cylinder 8, telescopic cylinder 13 and geared motor 4 are all equipped with switches and are connected to an external power source. Telescopic cylinder 8, telescopic cylinder 13 and geared motor 4 can be operated independently.

[0052] More specifically, the single-sided narrowing and obstacle simulation component also includes a support frame 7, which is fixed to the body of the reduction motor 4. The upper end of the support shaft 5 is rotatably connected to the support frame 7. The support frame 7 can improve the stability of the rotation of the support shaft 5, thereby ensuring that the obstacle plate 6 can rotate reliably.

[0053] More specifically, the turning test assembly also includes an optical axis 10 and a limiting block 11. The optical axis 10 is arranged horizontally and one end is fixed to the baffle 9. The axis of the optical axis 10 is perpendicular to the surface of the wall panel 3. The optical axis 10 is located above the telescopic cylinder 8. The limiting block 11 is fixed on the road plate 2. The limiting block 11 is provided with a through hole 1 and a through hole 2. The optical axis 10 slides through the through hole 1, and the telescopic shaft of the telescopic cylinder 8 passes through the through hole 2. The telescopic cylinder 8 can reliably drive the baffle 9 to move, and the baffle 9 will not tilt.

[0054] More specifically, the turning test assembly also includes a rectangular protective plate 12. The protective plate 12 is arranged vertically, and its length direction is the same as that of the road plate 2. There are two protective plates 12 with their ends aligned. The baffle 9, telescopic cylinder 8, optical axis 10, and limit block 11 are all centrally located between the two protective plates 12. When the unmanned forklift 1 travels on test section one and test section two, it will not collide with the telescopic cylinder 8, optical axis 10, and limit block 11.

[0055] A scale line 23 is provided on the upper surface of the road plate 2 along its length. The scale line 23 is located between test section one and test section two. The end of the baffle 9 away from the telescopic cylinder 8 can be aligned with the scale line 23. The shortest distance between the baffle 9 and the wall plate 3 can be accurately determined through the scale line 23.

[0056] When using this detection device:

[0057] The unmanned forklift 1 is positioned on test section two. The forklift 1 is started and moved towards wall panel 3. When the forklift 1 reaches a certain speed, the reduction motor 4 is activated. The reduction motor 4 causes the obstacle panel 6 to swing rapidly, causing the end of the obstacle panel 6 away from the support shaft 5 to enter the inner side of test section two. Furthermore, the surface of the obstacle panel 6 is almost perpendicular to the length of the roadbed panel 2. At this point, the forklift 1 detects the obstacle panel 6 ahead and stops abruptly. Alternatively, if only a small portion of the obstacle panel 6 enters the inner side of test section two, the width of test section two narrows at this point. When the forklift 1 reaches this point, it automatically adjusts its direction to pass smoothly. Through the above simulation, the emergency obstacle avoidance capability and reversing capability of the unmanned forklift 1 can be measured.

[0058] The driverless forklift 1 is located on test section 2. The driverless forklift 1 is started and moves closer to the wall panel 3. The telescopic cylinder 2 13 is controlled so that the telescopic cylinder 2 13 drives the abutment block 14 to move. When the abutment block 14 moves closer to the wall panel 3, the top plate 15 rises. The end of the connecting plate 16 away from the top plate 15 is always in contact with the upper surface of the road plate 2. The driverless forklift 1 can pass over the top plate 15. The higher the top plate 15 is, the better the obstacle passage ability of the driverless forklift 1.

[0059] The unmanned forklift 1 is located on test section two. The telescopic cylinder 8 is controlled to move the baffle 9. The distance between the baffle 9 and the wall plate 3 is adjustable. The unmanned forklift 1 starts to perform automatic turning action. The unmanned forklift 1 turns from test section two to test section one. The smaller the distance between the baffle 9 and the wall plate 3, the better the turning ability of the unmanned forklift 1 is required. The turning ability here refers to the turning posture, turning path and minimum turning radius of the unmanned forklift 1. The automatic turning ability of the unmanned forklift 1 is judged by setting the distance between the baffle 9 and the wall plate 3.

[0060] The unmanned forklift 1 is located on test section one. The unmanned forklift 1 can perform braking distance tests with or without load on test section one. After reaching a certain speed on test section one, the unmanned forklift 1 brakes suddenly to a complete stop. The distance from the position of the vehicle body when the unmanned forklift 1 starts to brake suddenly to the position of the vehicle body after it comes to a complete stop can be measured using the scale line 20 in this application. The determination of the position of the vehicle body when the unmanned forklift 1 starts to brake suddenly is prior art. In this embodiment, a high-speed camera can be arranged on test section one. The high-speed camera can clearly capture the scale line 20. When the unmanned forklift 1 brakes suddenly, the wheels of the unmanned forklift 1 lock up, and the high-speed camera can capture the scale line 20 corresponding to the wheel lockup.

[0061] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the invention. Therefore, the invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
