Detailed Description

The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

Referring to fig. 1, the present embodiment provides a test bench 10, where the test bench 10 may be used to test driving performances of an unmanned vehicle, and the test bench 10 may include: a first test bench 100, a first rotational connection 300 and a second test bench 200.

Wherein, the first rotating connector 300 is arranged at the edge of the table top of the first test bench 100; and the edge of the top of the second test bench 200 is rotatably connected to the first test bench 100 by connecting the first rotary connector 300. In this way, the first test bench 100 is rotatably deployed around the first rotary joint 300 with respect to the second test bench 200, as required for use or storage; alternatively, the first test stand 100 may also be folded in rotation about the first rotational connection 300 with respect to the second test stand 200.

Specifically, as shown in fig. 2A and 2B, the first testing table 100 may be a horizontal testing table or a slope testing table, which may be selected according to actual requirements.

In this embodiment, the first testing platform 100 may include: a first panel 110 and a first bracket 120.

Specifically, first panel 110 and first support 120 may be made of a steel material to ensure reliability and durability of first test stand 100. First panel 110 includes a first upper surface 111 and a first lower surface that are opposite and parallel, the first lower surface of first panel 110 may be used for fixed connection, such as welding, with first support 120, and first upper surface 111 of first panel 110 serves as a table top for first test bed 100 for use in the unmanned vehicle driving test.

In addition, since the splicing manner of the top of the first testing platform 100 and the top of the second testing platform 200 is adjusted by rotating in the present embodiment, and the corresponding adjusting testing platform 10 is unfolded or folded, the shape of the first panel 110 needs to be convenient for splicing with the top of the second testing platform 200, for example, the shape of the first panel 110 may be set to be a polygon which is convenient for splicing, such as a rectangle, a triangle, a diamond, and the like.

Further, since the unmanned vehicle needs to travel on the first upper surface 111 of the first panel 110, the roughness of the first upper surface 111 is different according to the type of the unmanned vehicle travel test. For example, if the driving ability of the unmanned vehicle on a smooth road needs to be tested, the first upper surface 111 can be polished smooth, so that the friction coefficient is small; if the driving capacity of the unmanned vehicle on a rough road surface needs to be tested, some anti-skid protrusions can be arranged on the first upper surface 111, so that the friction coefficient of the unmanned vehicle is relatively large; if the driving ability of the unmanned vehicle on the bumpy road needs to be tested, the first upper surface 111 can be provided with bulges with larger sizes, so that the first upper surface is uneven.

As shown in fig. 3 (fig. 3 is an example of the first testing table 100 as a ramp testing table, but not limited thereto), in some embodiments of the first testing table 100, the first testing table 100 further includes: first roller 130, the first roller 130 may be installed at an end of the first support 120 far from the first panel 110, and when the first test platform 100 is placed on the ground, the first roller 130 contacts the ground to facilitate movement of the first test platform 100.

It should be noted that the specific number and the specific installation position of the first rollers 130 may be selected according to actual requirements, for example, the number of the first rollers 130 may be 4, and the 4 first rollers 130 may be installed at 4 top corners of the bracket away from the first panel 110 in a one-to-one correspondence manner, so as to form a good stressed support, which is convenient for the first testing platform 100 to move.

As shown in fig. 4 (fig. 4 is an example of the first testing table 100 being a ramp testing table, but not limited thereto), in some embodiments of the first testing table 100, the first testing table 100 may further include: the first lifting assembly 140 with adjustable supporting length, the first lifting assembly 140 may be a hydraulic lifter, a stud and nut assembly, etc.

In this embodiment, the first lifting assembly 140 is mounted on the first support 120, and the height and/or inclination of the top of the first testing platform 100 can be changed by adjusting the supporting length of the first lifting assembly 140 according to actual testing requirements, so as to meet the actual testing requirements. For example, the number of the first lifting assemblies 140 may be 4, and 4 first lifting assemblies 140 are correspondingly mounted at 4 top corners of the bracket far away from the first panel 110, so that the first test platform 100 is lifted integrally or only one end of the first test platform 100 is lifted by adjusting the respective heights of the 4 first lifting assemblies 140, thereby adjusting the height and/or inclination of the top of the first test platform 100. For another example, the number of the first lifting assemblies 140 may be 2, and the 2 first lifting assemblies 140 are correspondingly mounted to the 2 top corners of the bracket, which are far away from the first panel 110 and located on the same side, one by one, so that by adjusting the respective heights of the 2 first lifting assemblies 140, one end of the first testing platform 100 can be lifted, thereby adjusting the slope of the top surface of the first testing platform 100.

It should be noted that, if the scheme that the first lifting assembly 140 and the first roller 130 are disposed is actually adopted, when the height and/or the inclination of the top of the first testing table 100 is adjusted by the first lifting assembly 140, the first roller 130 is no longer in contact with the ground or the contact degree between the first roller 130 and the ground is reduced, so that the load of the first roller 130 is reduced, and the service life of the first roller 130 is prolonged.

Specifically, as shown in fig. 5A and 5B, the second testing table 200 may be a horizontal testing table or a slope testing table, which may be selected according to actual requirements.

In this embodiment, the second testing platform 200 may include: a second panel 210 and a second bracket 220.

Specifically, the second panel 210 and the second bracket 220 may be made of steel material to ensure reliability and durability of the second test stand 200. The second panel 210 includes a second upper surface 211 and a second lower surface 212 which are opposite and parallel, the second lower surface 212 of the second panel 210 can be used for being fixedly connected with the second bracket 220, such as being welded, and the second upper surface 211 of the second panel 210 can be used as a table of the second test bench 200 for the unmanned vehicle driving test.

In addition, since the splicing manner of the top of the first testing platform 100 and the top of the second testing platform 200 is adjusted by rotating in the present embodiment, and the corresponding adjustable testing platform 10 is unfolded or folded, the shape of the second panel 210 needs to be convenient for splicing with the top of the first testing platform 100, for example, the shape of the second panel 210 can also be set to be a polygon matching with the polygon of the first panel 110, such as a rectangle, a triangle, a diamond, etc.

Further, since the unmanned vehicle needs to travel on the second upper surface 211 of the second panel 210, the roughness of the second upper surface 211 is different according to the type of the unmanned vehicle travel test. For example, if the driving ability of the unmanned vehicle on a smooth road surface needs to be tested, the second upper surface 211 can be polished smooth, so that the friction coefficient is small; if the driving capacity of the unmanned vehicle on a rough road surface needs to be tested, the second upper surface 211 can be provided with a plurality of anti-skid bulges, so that the friction coefficient of the unmanned vehicle is larger; if the driving ability of the unmanned vehicle on the bumpy road needs to be tested, the second upper surface 211 can be provided with bulges with larger sizes, so that the second upper surface is uneven.

As shown in fig. 6 (fig. 6 is an example of the second testing station 200 being a ramp testing station, but not limited thereto), in some embodiments of the second testing station 200, the second testing station 200 may further include: a second roller 230, the second roller 230 may be installed at an end of the second bracket 220 far from the second panel 210, and when the second test platform 200 is placed on the ground, the second roller 230 contacts the ground to facilitate the movement of the second test platform 200.

It should be noted that the specific number and the specific installation of the second rollers 230 may be selected according to actual requirements, for example, the number of the second rollers 230 may also be 4, and the 4 second rollers 230 may be correspondingly installed at 4 top corners of the bracket away from the first panel 110, so as to form a good stressed support, which is convenient for the second testing platform 200 to move.

As shown in fig. 7 (fig. 7 is an example of the second testing station 200 being a ramp testing station, but not limited thereto), in some embodiments of the second testing station 200, the second testing station 200 may further include: a second lifting assembly 240 with adjustable supporting length, the second lifting assembly 240 may be a hydraulic lifter, a stud and nut assembly, etc.

In this embodiment, the second lifting assembly 240 is mounted on the second bracket 220, and the supporting length of the second lifting assembly 240 is adjusted according to actual testing requirements, so that the height and/or inclination of the top of the second testing platform 200 can be changed to meet the actual testing requirements. For example, the number of the second lifting assemblies 240 may be 4, and the 4 second lifting assemblies 240 are correspondingly mounted at 4 top corners of the bracket far away from the second panel 210, so that the second test platform 200 is lifted integrally or only one end of the second test platform 200 is lifted by adjusting the respective heights of the 4 second lifting assemblies 240, thereby adjusting the height and/or inclination of the top of the second test platform 200. For another example, the number of the second lifting assemblies 240 may be 2, and the 2 second lifting assemblies 240 are correspondingly mounted to the bracket away from the second panel 210 and located at 2 top corners of the same side one by one, so that by adjusting the respective heights of the 2 second lifting assemblies 240, one end of the second testing platform 200 can be lifted, thereby adjusting the slope of the top surface of the second testing platform 200.

It should be noted that, if the scheme that the second lifting assembly 240 and the second roller 230 are both provided is actually adopted, when the height and/or the inclination of the top of the second testing platform 200 is adjusted by the second lifting assembly 240, the second roller 230 can be prevented from contacting the ground or the contact degree between the second roller 230 and the ground is reduced, so that the load of the second roller 230 is reduced, and the service life of the second roller 230 is prolonged.

Referring to fig. 1, in the present embodiment, the first rotating connector 300 may be a hinge, a rotating shaft, or other rotating connectors. The first rotational connector 300 may connect the edge of the first panel 110 and the edge of the second panel 210 to achieve the relative rotation of the first test stand 100 and the second test stand 200. However, the first rotating connection member 300 is connected in a different manner, and the first test stand 100 and the second test stand 200 are rotated in different directions. For example, if the first rotation connector 300 is horizontally disposed, the first test platform 100 rotates around the first rotation connector 300 on a vertical plane with respect to the second test platform 200; for example, if the first rotary joint 300 is vertically disposed, the first test stand 100 rotates on a horizontal plane relative to the second test stand 200 around the first rotary joint 300.

The rotation in the vertical plane and the rotation in the horizontal plane will be described separately with reference to the application scenario.

Referring to fig. 8A to 8G, if the first testing platform 100 and the second testing platform 200 are both slope testing platforms. Wherein the first test bench 100 comprises a first end 101 and a second end 102 opposite to each other, and a first side 103 located between the first end 101 and the second end 102, and the table top of the first test bench 100 is gradually raised along the first end 101 toward the second end 102; and, the second test stand 200 comprises a third end 201 and a fourth end 202 opposite to each other, and a second side 203 located between the third end 201 and the fourth end 202, and the mesa of the second test stand 200 is gradually raised along the third end 201 toward the fourth end 202.

In this case, if it is required to splice a slope by rotating the first test stand 100 and the second test stand 200 on the vertical plane to test the climbing ability of the unmanned vehicle, it is required that the second end 102 and the third end 201 of the second test stand 200 have the same height. Thus, when the first test bench 100 is rotated on the vertical plane around the first rotational connector 300 relative to the second test bench 200 to the unfolded state shown in FIG. 8A, the first end 101, the second end 102, the third end 201, and the fourth end 202 are in the same plane, so that the table top of the first test bench 100 and the table top of the second test bench 200 can be spliced into an inclined plane. And when the first test bench 100 is rotated on the vertical plane about the first rotational connection 300 with respect to the second test bench 200 to the folded state shown in fig. 8B, the top of the first test bench 100 can overlap the top of the second test bench 200, so that the test bench 10 is in the folded state.

If it is necessary to splice a folded surface by rotating the first test stand 100 and the second test stand 200 on the vertical surface to test the driving ability of the unmanned vehicle under the change of the slope, it is necessary that the heights of the second end 102 and the fourth end 202 are the same, or that the heights of the second end 102 and the third end 201 are the same but the slopes of the top surfaces of the first test stand 100 and the second test stand 200 are different. Thus, when the first testing platform 100 rotates around the first rotating connector 300 on the vertical plane relative to the second testing platform 200 to the unfolded state shown in fig. 8C or fig. 8D, the first end 101, the second end 102, the third end 201 and the fourth end 202 are in different planes, so that the table top of the first testing platform 100 and the table top of the second testing platform 200 are spliced into a folded plane. And when the first test bench 100 is rotated on the vertical plane about the first rotational connection 300 with respect to the second test bench 200 to the folded state shown in fig. 8E or 8F, the top of the first test bench 100 can overlap the top of the second test bench 200, so that the test bench 10 is in the folded state.

If it is required to switch the spliced surfaces between the inclined surface and the folded surface by rotating the first testing table 100 and the second testing table 200 on the horizontal plane to test the climbing capability and the traveling capability of the unmanned vehicle under the condition of changing the slope, the heights of the second end 102 and the fourth end 202 of the second testing table 200 are required to be the same. Thus, when the first test stand 100 is rotated on the vertical plane around the first rotational connector 300 relative to the second test stand 200 to the unfolded state shown in fig. 8H, the first end 101, the second end 102, the third end 201 and the fourth end 202 are in different planes, so that the table top of the first test stand 100 and the table top of the second test stand 200 can be spliced into a folded plane. When the first testing platform 100 rotates around the first rotating connector 300 to the folded state shown in fig. 8G on the vertical plane relative to the second testing platform 200, the first end 101, the second end 102, the third end 201, and the fourth end 202 are in the same plane, so that the top of the first testing platform 100 and the top of the second testing platform 200 can be spliced into an inclined plane.

It will be appreciated that in the case of figures 8G and 8H, the test stations 10 are stored or moved when in the collapsed position, since the volume of the test stations 10 in the extended position is generally greater than the volume of the test stations in the collapsed position, which also reduces the space occupied by the test stations and makes them easier to move and store.

Referring to fig. 9A and 9B, if the first testing station 100 is a ramp testing station and the second testing station 200 is a horizontal testing station. Wherein the first test bench 100 comprises a first end 101 and a second end 102 opposite to each other, the table top of the first test bench 100 gradually rises along the first end 101 towards the second end 102; and, second test station 200 includes opposing third and fourth ends 201 and 202.

In this case, if the first testing table 100 and the second testing table 200 rotate on the horizontal plane, the table tops of the first testing table 100 and the second testing table 200 cannot be spliced to form a continuous surface, and therefore, the second end 102 of the first testing table 100 needs to be as high as the third end 201 of the second testing table 200, so that the second end can be spliced to form a folded surface when rotating on the vertical plane. As shown in fig. 9A, when the first test stand 100 rotates on the vertical plane relative to the second test stand 200 around the first rotating connector 300 to the unfolded state shown in fig. 9A, the second end 102 contacts the third end 201, and the first end 101, the second end 102, the third end 201, and the fourth end 202 are in different planes, so that the table top of the first test stand 100 and the table top of the second test stand 200 can be spliced into a folded plane. And when the first test bench 100 is rotated on the vertical plane about the first rotational connection 300 with respect to the second test bench 200 to the folded state shown in fig. 9B, the top of the first test bench 100 can overlap the top of the second test bench 200, so that the test bench 10 is in the folded state.

Referring to fig. 10A and 10D, if the first testing platform 100 and the second testing platform 200 are both horizontal testing platforms. Then, the first test bench 100 comprises a first end 101 and a second end 102 opposite to each other, a first side 103 of the first test bench 100 is arranged between the first end 101 and the second end 102, and the heights of the first end 101 and the second end 102 are the same, so that the table top of the first test bench 100 is horizontal; and, the second test bench 200 comprises a third end 201 and a fourth end 202 which are opposite, a second side 203 of the second test bench 200 is arranged between the third end 201 and the fourth end 202, and the heights of the third end 201 and the fourth end 202 are the same, so that the table top of the second test bench 200 is horizontal.

In this case, whether the first test stand 100 and the second test stand 200 rotate on the horizontal plane or the vertical plane, the heights of the second end 102 and the third end 201 are required to be the same so that the levels of the first test stand 100 and the second test stand 200 can be spliced to form a plane.

As shown in fig. 10A, when the first test stand 100 rotates on the vertical plane around the first rotating connector 300 relative to the second test stand 200 to the unfolded state shown in fig. 10A, the first end 101, the second end 102, the third end 201 and the fourth end 202 are in the same plane, so that the table top of the first test stand 100 and the table top of the second test stand 200 can be spliced into a plane. And when the first test bench 100 is rotated on the vertical plane about the first rotational connection 300 with respect to the second test bench 200 to the folded state shown in fig. 10B, the top of the first test bench 100 can overlap the top of the second test bench 200, so that the test bench 10 is in the folded state.

As shown in fig. 10C, when the first test stand 100 rotates around the first rotating connector 300 on the horizontal plane relative to the second test stand 200 to the unfolded state shown in fig. 10C, the first end 101, the second end 102, the third end 201, and the fourth end 202 are in the same plane, so that the table top of the first test stand 100 and the table top of the second test stand 200 can be spliced into a plane. When the first test bench 100 is rotated in a horizontal plane about the first rotating connector 300 relative to the second test bench 200 to the folded state shown in fig. 10D, the first side 103 can contact the second side 203, so that the test bench 10 is in the folded state. It can be understood that in this case, the shape of the spliced plane can be changed by rotating in the horizontal plane, so as to meet more scene requirements.

It will also be appreciated that in the case of figures 10C and 10D, storage or movement of the test stations 10 in the collapsed position may also reduce the space occupied by them to make them more convenient to move and store, since the test stations 10 are generally more bulky in the extended position than in the collapsed position.

As shown in fig. 11, in some embodiments of the present application, the testing station 10 further includes: the third testing station 400. Wherein the edge of the third test station 400 table top may interface with the edge of the second test station 200 table top.

Specifically, as shown in fig. 12A and 12B, the third test station 400 may be a horizontal test station or a slope test station, which may be selected according to actual requirements.

In this embodiment, the third testing platform 400 may include: a third panel 410 and a third bracket 420.

Specifically, the third panel 410 and the third bracket 420 may be made of a steel material to ensure reliability and durability of the third test bench 400. The third panel 410 includes a third upper surface 411 and a third lower surface 412 which are opposite and parallel, the third lower surface 412 of the third panel 410 can be used for being fixedly connected with the third bracket 420, such as being welded, and the third upper surface 411 of the third panel 410 is used as a table top of the third test bench 400 for the unmanned vehicle driving test.

In addition, since the top of the third test stand 400 needs to be docked with the top of the second test stand 200 for the unmanned vehicle to run, the shape of the third panel 410 needs to be convenient for it to be docked with the top of the second test stand 200, for example, the third panel 410 may also be shaped as a polygon that is configured as a rectangle, triangle, diamond, etc. that matches the polygon of the second panel 210.

Further, since the unmanned vehicle needs to travel on the third upper surface 411 of the third panel 410, the roughness of the third upper surface 411 is different according to the type of the unmanned vehicle travel test. For example, if the driving ability of the unmanned vehicle on a smooth road needs to be tested, the third upper surface 411 can be polished smooth, so that the friction coefficient is small; if the driving capability of the unmanned vehicle on a rough road surface needs to be tested, some anti-skid protrusions can be arranged on the third upper surface 411, so that the friction coefficient is larger; if the driving ability of the unmanned vehicle on a bumpy road needs to be tested, a plurality of bulges with larger sizes can be arranged on the third upper surface 411 to make the unmanned vehicle uneven.

As shown in fig. 13 (fig. 13 is an example, but not limited to, in which the third testing station 400 is a ramp testing station), in some embodiments of the third testing station 400, the third testing station 400 may further include: a third roller 430, the third roller 430 may be installed at an end of the third support 420 far from the third panel 410, and when the third test bench 400 is placed on the ground, the third roller 430 is in contact with the ground to facilitate movement of the third test bench 400.

It should be noted that the specific number and the specific installation of the third rollers 430 may be selected according to actual requirements, for example, the number of the third rollers 430 may also be 4, and the 4 third rollers 430 may be correspondingly installed at 4 top corners of the bracket far from the third panel 410, so as to form a good stressed support, which is convenient for the third testing platform 400 to move.

As shown in fig. 14 (fig. 14 is an example of the third testing station 400 as a ramp testing station, but not limited thereto), in some embodiments of the third testing station 400, the third testing station 400 may further include: the third lifting assembly 440 with adjustable supporting length, the third lifting assembly 440 can also be a hydraulic lifter, a stud and nut assembly, etc.

In this embodiment, the third lifting assembly 440 is mounted on the third support 420, and the supporting length of the third lifting assembly 440 is adjusted according to actual testing requirements, so that the height and/or inclination of the top of the third testing platform 400 can be changed to meet the actual testing requirements. For example, the number of the third lifting assemblies 440 may be 4, and the 4 third lifting assemblies 440 are correspondingly mounted at 4 top corners of the bracket far away from the third panel 410, so that the third testing platform 400 is lifted integrally or only one end of the third testing platform 400 is lifted by adjusting the respective heights of the 4 third lifting assemblies 440, thereby adjusting the height and/or inclination of the top of the third testing platform 400. For another example, the number of the third lifting assemblies 440 may be 2, and the 2 third lifting assemblies 440 are correspondingly mounted to the bracket away from the third panel 410 and located at 2 vertex angles of the same side one by one, so that by adjusting the respective heights of the 2 third lifting assemblies 440, one end of the third testing platform 400 can be lifted, and the inclination of the top surface of the third testing platform 400 can be adjusted.

It should be noted that, if the scheme that the third lifting assembly 440 and the third roller 430 are disposed is actually adopted, when the height and/or the inclination of the top of the third testing table 400 is adjusted by the third lifting assembly 440, the third roller 430 may not contact the ground any more or the contact degree between the third roller 430 and the ground is reduced, so that the load of the third roller 430 is reduced, and the service life of the third roller 430 is prolonged.

In this embodiment, according to the actual use requirement, the third testing platform 400 and the second testing platform 200 may be detachably connected or rotatably connected. Which will be described separately below with reference to the accompanying drawings.

For detachable connections:

as shown in fig. 15, the first testing station 100 and the second testing station 200 are both slope testing stations, and the third testing station 400 is a horizontal testing station. The third testing platform 400 comprises a fifth end 401 and a sixth end 402 which are opposite to each other, and the heights of the fifth end 401 and the sixth end 402 are the same, and the heights of the fifth end 401 and the fourth end 202 are also the same. Then when the edge of the third test station 400 table top is butted against the edge of the second test station 200 table top, i.e. the fifth end 401 is butted against the fourth end 202. The third rack 420 under the top of the third testing table 400 and the second rack 220 under the top of the second testing table 200 can be detachably connected by being clamped by the clamping member 500.

For the rotational connection:

as shown in fig. 16, in this embodiment, the testing platform 10 further includes: a second rotational connection 600. Can be a hinge, a rotating shaft and other rotating connectors. The second rotary joint 600 may connect the edge of the second panel 210 and the edge of the third panel 410 to achieve the relative rotation of the second test stand 200 and the third test stand 400. In addition, the second rotary joint 600 has different connection modes, and the second test stand 200 and the third test stand 400 have different rotation directions. For example, the second rotary joint 600 is arranged in a horizontal direction, so that the second test stand 200 rotates around the second rotary joint 600 on a vertical plane with respect to the third test stand 400; for example, if the second rotary joint 600 is vertically disposed, the second testing table 200 rotates around the second rotary joint 600 on a horizontal plane with respect to the third testing table 400.

It can be appreciated that the third test stand 400 is provided without affecting the relative rotation of the first test stand 100 and the second test stand 200. The principle of the relative rotation of the second testing platform 200 and the third testing platform 400 is substantially the same as that of the relative rotation of the first testing platform 100 and the second testing platform 200, and thus, the description thereof will not be repeated.

It should be noted that, in addition to the above-mentioned structure, a new structure may be added according to actual needs, such as shown in fig. 18, in the case that the first test stand 100 and the second test stand 200 are slope test stands, and the third test stand 400 is a horizontal test stand. The test station 10 may also include a fourth test station 700 and a fifth test station 800, both ramp test stations. In this case, after the first testing platform 100 is rotatably connected to the second testing platform 200 through the rotating connection member, and the fourth testing platform 700 is connected to the fifth testing platform 800 through the rotating connection member, the rotatably connected first testing platform 100 and second testing platform 200 are detachably connected to one side of the third testing platform 400 through the clamping member 500, and the rotatably connected fourth testing platform 700 and fifth testing platform 800 are detachably connected to the other side of the third testing platform 400 through the clamping member 500, so that the third testing platform 400 has a symmetrical structure at both sides.

In summary, by providing the first rotating connecting member, the test bench can be folded around the first rotating connecting member in a rotating manner relative to the second test bench or unfolded around the first rotating connecting member in a rotating manner relative to the second test bench according to the use or storage requirement. And the test bench is folded, so that the volume of the test bench can be reduced when the test bench is moved and stored, and the test bench is more convenient to move and store.
