[0027] Embodiments of the present utility model will be described in detail below. Examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the drawings are exemplary only for explaining the present utility model and should not be construed as limiting the present utility model.
[0028] Reference is made below toFigures 1-4 Describe a verification device 100 for a steer-by-wire system according to an embodiment of the present utility model. The verification device 100 can be used to complete the durability verification of the steer-by-wire system, and the verification device 100 can also be used to evaluate the performance of the steer-by-wire system.
[0029] The verification device 100 for a steer-by-wire system according to an embodiment of the present utility model, as Figures 1-4 shown, the steer-by-wire system can include a steer-by-wire column assembly 200 and a steering gear assembly 300. The verification device 100 can include: a base 10, a first mounting bracket 20, a second mounting bracket 30, and a load input mechanism. The base 10 is used to mount the steering gear assembly 300. The first mounting bracket 20 is provided on the base 10, and the first mounting bracket 20 is selectively rotatable about a first axis extending along a first direction. The second mounting bracket 30 is provided on the first mounting bracket 20, and the second mounting bracket 30 is selectively rotatable about a second axis extending along a second direction. The first direction and the second direction are perpendicular. The second mounting bracket 30 is used to mount the steer-by-wire column assembly 200, and the load input mechanism is used to connect with the steer-by-wire column assembly 200.
[0030] It should be noted that in the durability verification of the steer-by-wire system, the operation is cumbersome, and there is no verification device to connect with the steer-by-wire system to complete the durability verification of the steer-by-wire system. Therefore, it is necessary to design a verification device for the durability verification of the steer-by-wire system.
[0031] Based on this, an embodiment of the present application proposes a verification device 100 for a steer-by-wire system. The steer-by-wire system can include a steer-by-wire column assembly 200 and a steering gear assembly 300. The steering gear assembly 300 can be connected to the steer-by-wire column assembly 200 through a wire harness. When the steer-by-wire column assembly 200 rotates, the steer-by-wire column assembly 200 can transmit signals through the wire harness, and the steer-by-wire column assembly 200 can drive the steering gear assembly 300 to work. Along the height direction of the verification device 100, the base 10 can be located at the bottom of the verification device 100, and the base 10 can be used to mount the steering gear assembly 300. Along the length direction of the steering gear assembly 300, both ends of the steering gear assembly 300 can be connected to a load 310. The steering gear assembly 300 can drive the load 310 to move longitudinally along the length direction of the steering gear assembly 300, and the effect of simulating vehicle steering can be achieved.
[0032] The first mounting bracket 20 can be connected to the base 10. Along the height direction of the verification device 100, the first mounting bracket 20 can be located above the base 10. The first axis can extend along the first direction (i.e., the height direction of the verification device 100). When the verification device 100 of the steer-by-wire system is as Figure 1 oriented, the first direction can be Figure 1In the Z direction, the first mounting bracket 20 can selectively rotate about the first axis, and the first mounting bracket 20 can rotate relative to the base 10. The second mounting bracket 30 can be connected to the first mounting bracket 20. Along the first direction, the second mounting bracket 30 can be located above the first mounting bracket 20. When the first mounting bracket 20 rotates about the first axis, the first mounting bracket 20 can drive the second mounting bracket 30 to rotate together. The second axis can extend along the second direction. When the verification device 100 of the steer-by-wire system is arranged as Figure 1 in the direction, the second direction can be Figure 1 in the P direction in, and the first direction and the second direction are perpendicular.
[0033] The second mounting bracket 30 can selectively rotate about the second axis, and the second mounting bracket 30 is rotatably arranged on the first mounting bracket 20. The second mounting bracket 30 can be used to mount the steer-by-wire column assembly 200. The second mounting bracket 30 can include a first mounting plate 31. The steer-by-wire column assembly 200 can be fixedly connected to the first mounting plate 31 by means of bolt connection, snap connection, etc. The first mounting plate 31 can be used to support the steer-by-wire column assembly 200. When the second mounting bracket 30 rotates about the second axis, the second mounting bracket 30 can drive the steer-by-wire column assembly 200 to rotate together. When the first mounting bracket 20 rotates about the first axis, the steer-by-wire column assembly 200 can rotate about the first axis under the drive of the first mounting bracket 20. When it is necessary to adjust the angle of the steer-by-wire column assembly 200, the first mounting bracket 20 and / or the second mounting bracket 30 can be selectively rotated. When it is not necessary to adjust the angle of the steer-by-wire column assembly 200, the second mounting bracket 30 is fixedly connected to the first mounting bracket 20, and the first mounting bracket 20 is fixedly connected to the base 10, so as to achieve the effect of fixing the angle of the steer-by-wire column assembly 200.
[0034] The load input mechanism can be connected to the steer-by-wire column assembly 200. The load input mechanism can include a first input shaft 40, and the steer-by-wire column assembly 200 can include a second input shaft 210. When assembling the steer-by-wire column assembly 200 and the verification device 100 of the steer-by-wire system, the first input shaft 40 of the load input mechanism can be connected to the second input shaft 210 of the steer-by-wire column assembly 200 through a coupling, and a dial indicator can be used to verify whether the first input shaft 40 and the second input shaft 210 are coaxially arranged. When the first input shaft 40 and the second input shaft 210 are coaxially arranged, the verification device 100 of the steer-by-wire system can drive the steer-by-wire column assembly 200 to rotate through the load input mechanism. If the first input shaft 40 and the second input shaft 210 are not coaxially arranged, the load input mechanism cannot drive the steer-by-wire column assembly 200 to rotate. The first mounting bracket 20 and / or the second mounting bracket 30 can be selectively rotated to adjust the angle of the second input shaft 210, so that the angle of the second input shaft 210 can be adapted to the angle of the first input shaft 40, and the first input shaft 40 and the second input shaft 210 can be coaxially arranged.
[0035] By selectively rotating the first mounting bracket 20 and the second mounting bracket 30, the angle of the wire-controlled pipe string assembly 200 can be adjusted multi-directionally and precisely, so that the second input shaft 210 of the wire-controlled pipe string assembly 200 can be coaxially arranged with the first input shaft 40 of the load input mechanism, and the effect that the load input mechanism drives the wire-controlled pipe string assembly 200 to rotate can be achieved. Thus, the durability verification of the wire-controlled steering system can be completed, and the effect that the verification device 100 evaluates the performance of the wire-controlled steering system can be realized.
[0036] In some embodiments of the present invention, the first direction is the vertical direction and the second direction is the horizontal direction.
[0037] When the verification device 100 is used for the durability verification of the wire-controlled steering system, the base 10 can be arranged on the ground. The first direction can be the vertical direction and the second direction can be the horizontal direction. By rotating the first mounting bracket 20 around the first axis and rotating the second mounting bracket 30 around the second direction, the effect of adjusting the angle of the wire-controlled pipe string assembly 200 multi-directionally and precisely can be achieved, so that the second input shaft 210 of the wire-controlled pipe string assembly 200 can cooperate with the initial axial direction of the first input shaft 40 of the load input mechanism, thereby achieving the effect that the load input mechanism drives the wire-controlled pipe string assembly 200 to rotate.
[0038] In some embodiments of the present invention, as Figures 1-3 shown, the base 10 may include: a first plate body 11 and a support frame 12. The support frame 12 is fixedly arranged on the first plate body 11, and the first mounting bracket 20 is arranged on the support frame 12 and above the support frame 12.
[0039] The first plate body 11 and the support frame 12 can be arranged along the first direction. The support frame 12 can be located above the first plate body 11, and the support frame 12 can be fixedly connected to the first plate body 11 by means of snap connection, bolt connection, etc. As an example, the support frame 12 can include a support plate and a plurality of support rods 122. The plurality of support rods 122 can be used to support the support plate, and the plurality of support rods 122 can be evenly distributed along the circumferential direction of the support frame 12. A first connecting plate 1221 is connected to the end of each support rod 122 facing away from the support plate. The first connecting plate 1221 can be configured as a plate body structure with a rectangular cross-section. Each first connecting plate 1221 is formed with a first assembly hole 1222. The first assembly hole 1222 can penetrate the corresponding first connecting plate 1221 along the first direction. The support frame 12 can be assembled with the first plate body 11 through a plurality of first connecting plates 1221. Bolts can be inserted through the first assembly holes 1222 and cooperate with the first plate body 11 for assembly. The plurality of first assembly holes 1222 can all be configured as elongated holes. The first assembly holes 1222 can extend along the length direction of the first plate body 11, so as to achieve the effect of adjusting the position of the support frame 12 along the length direction of the first plate body 11. When the verification device 100 of the steer-by-wire system is as Figure 1 oriented, the length direction of the first plate body 11 can be Figure 1 the X direction in
[0040] As an example, the first plate body 11 can be formed with a plurality of second assembly holes 111 extending along the width direction of the first plate body 11. The second assembly holes 111 can be configured as through holes with a T-shaped cross-section. When the verification device 100 of the steer-by-wire system is as Figure 1 oriented, the width direction of the first plate body 11 can be Figure 1 the Y direction in
[0041] Along the first direction, the first mounting bracket 20 can be located above the support frame 12. The first mounting bracket 20 can be connected to the support frame 12 by means of snap connection, bolt connection, etc. The first mounting bracket 20 can rotate relative to the support frame 12 about the first axis. The first mounting bracket 20 can be connected to the first plate body 11 through the support frame 12, and the first mounting bracket 20 can rotate relative to the first plate body 11 about the first axis.
[0042] In some embodiments of the present invention, such as Figures 1-3As shown, the verification device 100 of the steer-by-wire system may further include: a first fastener 50. The support frame 12 has a top plate 121, and a first hole 1211 is formed in the top plate 121. The first mounting bracket 20 has a bottom plate 21, and a second hole 211 is formed in the bottom plate 21. The top plate 121 and the bottom plate 21 are attached, and the first hole 1211 and the second hole 211 are opposite to each other. At least one of the first hole 1211 and the second hole 211 is configured as an arc-shaped hole. The first fastener 50 passes through the first hole 1211 and the second hole 211 to selectively lock or unlock the support frame 12 and the first mounting bracket 20.
[0043] The support frame 12 has a top plate 121 (i.e., the support plate in the above embodiment), and a first hole 1211 is formed in the top plate 121. The first hole 1211 may penetrate the top plate 121 along a first direction. The first mounting bracket 20 has a bottom plate 21, and a second hole 211 is formed in the bottom plate 21. The second hole 211 may penetrate the bottom plate 21 along the first direction. When the first mounting bracket 20 is connected to the support frame 12, the top plate 121 may be attached to the bottom plate 21, the upper surface of the top plate 121 may abut against the lower surface of the bottom plate 21, the first hole 1211 and the second hole 211 may be disposed opposite to each other, and the first hole 1211 and the second hole 211 may communicate with each other. At least one of the first hole 1211 and the second hole 211 is configured as an arc-shaped hole. The first hole 1211 may be configured as an arc-shaped hole, or the second hole 211 may be configured as an arc-shaped hole, or both the first hole 1211 and the second hole 211 may be configured as arc-shaped holes. In this embodiment of the present application, it is described by taking both the first hole 1211 and the second hole 211 being configured as arc-shaped holes as an example.
[0044] When the first hole 1211 and the second hole 211 are in communication, the first fastener 50 can pass through the first hole 1211 and the second hole 211 and be fixedly connected to the bottom plate 21. As an example, the first fastener 50 can be configured as a bolt with a threaded structure formed on its outer peripheral wall. After the first fastener 50 passes through the first hole 1211 and the second hole 211, it can be assembled with a lock nut. When the first fastener 50 is assembled with the lock nut and the lock nut abuts against the bottom plate 21 and cannot be tightened further, the first fastener 50 locks the support frame 12 and the first mounting frame 20. When the lock nut is separated from the bottom plate 21, the first fastener 50 unlocks the support frame 12 and the first mounting frame 20, and the first mounting frame 20 can rotate relative to the support frame 12, thereby achieving the effect of selectively locking or unlocking the support frame 12 and the first mounting frame 20 by the first fastener 50. According to whether it is necessary to adjust the angle of the wire-controlled column assembly 200, the support frame 12 and the first mounting frame 20 can be selectively locked or unlocked. When the first mounting frame 20 rotates relative to the support frame 12, the first hole 1211 and the second hole 211 can be partially staggered. By always keeping the first hole 1211 and the second hole 211 in a communicating state, the effect of locking the support frame 12 and the first mounting frame 20 by the first fastener 50 can be achieved.
[0045] In some embodiments of the present invention, the top plate 121 may further include a first pivot hole 1212. The first pivot hole 1212 may penetrate the top plate 121 along a first direction, and the first pivot hole 1212 may be a through hole. The first mounting frame 20 may further include a second pivot hole. The second pivot hole penetrates the bottom plate 21 along the first direction, and the second pivot hole may be a through hole. The first pivot hole 1212 may be located at the center position of the top plate 121, the second pivot hole may be located at the center position of the bottom plate 21, the first pivot hole 1212 and the second pivot hole may be oppositely arranged along the first direction, and the first pivot hole 1212 and the second pivot hole may be in communication. A first pivot pin may pass through the first pivot hole 1212 and the second pivot hole. The first pivot pin extends along the first direction, and the central axis of the first pivot pin may be collinear with the first axis. The first pivot pin may abut against the inner wall of the first pivot hole 1212, the first pivot pin may abut against the inner wall of the second pivot hole 12, and the first pivot pin may connect the top plate 121 and the bottom plate 21. When the first fastener 50 unlocks the first mounting frame 20 and the support frame 12, the first mounting frame 20 can rotate relative to the first pivot pin. And by providing the first pivot pin, when the first mounting frame 20 rotates relative to the support frame 12, it can be avoided that the first mounting frame 20 is separated from the support frame 12, which is beneficial to improving the working safety of the verification device 100 of the wire-controlled steering system.
[0046] In some embodiments of the present invention, there are multiple first fasteners 50, first holes 1211 and second holes 211, and the multiple first holes 1211 and second holes 211 are arranged along the rotation direction of the first mounting frame 20, and the multiple first fasteners 50 are respectively inserted into the corresponding first holes 1211 and the corresponding second holes 211.
[0047] There may be a plurality of first fasteners 50, a plurality of first holes 1211, and a plurality of second holes 211. The plurality of first holes 1211 may be arranged along the rotation direction of the first mounting frame 20, that is, the plurality of first holes 1211 may be arranged along the circumference of the first pivot hole 1212, and the plurality of first holes 1211 are arranged around the first pivot hole 1212. The plurality of second holes 211 may be arranged along the rotation direction of the first mounting frame 20, that is, the plurality of second holes 211 may be arranged along the circumference of the second pivot hole, and the plurality of second holes 211 are arranged around the second pivot hole. The plurality of first holes 1211 and the plurality of second holes 211 may be arranged one-to-one, and each first hole 1211 and each second hole 211 have a first fastener 50 correspondingly assembled therewith, and the plurality of fasteners may be respectively penetrated through the corresponding first hole 1211 and the corresponding second hole 211.
[0048] Multiple first holes 1211 can all be constructed as arc-shaped holes, and multiple second holes 211 can all be constructed as arc-shaped holes. The embodiment of the present application is described by taking the example that there are two first holes 1211 and two second holes 211, and both the two first holes 1211 are constructed as arc-shaped holes and both the two second holes 211 are constructed as arc-shaped holes. The two first holes 1211 are arranged and spaced apart along the rotation direction of the first mounting frame 20, and the two second holes 211 are arranged and spaced apart along the rotation direction of the first mounting frame 20. When the first mounting frame 20 rotates relative to the support frame 12, the two second holes 211 rotate along the rotation direction of the first mounting frame 20. Each second hole 211 is partially staggered with the corresponding first hole 1211. Each second hole 211 can be simultaneously connected to the two first holes 1211 on the top plate 121, which is beneficial to increase the range in which the first fastener 50 can lock the support frame 12 and the first mounting frame 20. The first mounting frame 20 can rotate at an angle of θ, and the range of θ can be between 0°-360°. When the first mounting frame 20 rotates at an angle between 0°-360°, the first fastener 50 can lock the support frame 12 and the first mounting frame 20, and the wire control column assembly 200 can adjust the angle in the range of 0°-360° in the plane around the first axis. By providing a plurality of first fasteners 50 , first holes 1211 and second holes 211 , the connection strength between the first mounting frame 20 and the support frame 12 can be improved, and the rotatable range of the first mounting frame 20 can be increased.

Both of the two second side plates 32 can be connected to the first mounting plate 31 by means such as welding and bolt connection. The two side plates are both located on the side of the first mounting plate 31 away from the wireline pipe string assembly 200. The two second side plates 32 are oppositely arranged and spaced apart in the second direction. Along the second direction, the two second side plates 32 are located between the two first side plates 22. The two first side plates 22 and the two second side plates 32 are assembled in one-to-one correspondence. Each first side plate 22 has a corresponding second side plate 32 for mating assembly. The corresponding first side plate 22 and the corresponding second side plate 32 can be connected by a pivot member 60. Both of the two first side plates 22 can be formed with a third pivot hole. The third pivot hole can penetrate the corresponding first side plate 22 along the second direction. Both of the two second side plates 32 can have a fourth pivot hole.
