[0036] In order to more clearly understand the above-mentioned objectives, features and advantages of the present disclosure, the scheme of the present disclosure will be further described below. It should be noted that the embodiments of the present disclosure and the features in the embodiments can be combined with each other without conflict.
[0037] In the following description, many specific details are set forth to facilitate a full understanding of the present disclosure, but the present disclosure may also be implemented in other ways different from those described herein; it is obvious that the embodiments in the specification are only part of the embodiments of the present disclosure, rather than all of the embodiments.
[0038] HWA (hand wheel actuator), a wire steering feel simulator, is a component of wire steering technology. Since the wire steering system eliminates the mechanical connection of the intermediate shaft in the traditional steering system, the front suspension and cabin design layout of the vehicle chassis become more flexible. Since the wire steering system eliminates the mechanical connection of the intermediate shaft in the traditional steering system, if the angle limiting mechanism is not added, the steering wheel connected to the HWA will be able to rotate without an angle limit range, which will damage the combination switch, clock spring, airbag coil and other devices installed on the HWA. In addition, the steering wheel rotation beyond the angle travel will disrupt the angle signal of the HWA, making it difficult to control the HWA and affecting the normal driving of the vehicle.
[0039] like Figures 1 to 8 As shown, an embodiment of the present application provides an angle limiting assembly, including a shell 1, a sliding member 2 and a rotating member. The shell 1 is provided with a slide groove 11, which extends along a first direction, and the first direction intersects with the tangent direction of the circumference of the shell 1. The circumference of the shell 1 refers to the circumference formed around the first rotation center with a certain point of the shell 1 as the first rotation center. For example, the cross-sectional shape of the shell 1 is circular, and the above-mentioned first rotation center can be the center of the circular shell 1.
[0040] The sliding member 2 is slidably connected to the slide slot 11, and the slide slot 11 has a first limit position 12 and a second limit position 13. The sliding member 2 moves between the first limit position 12 and the second limit position 13, and a plug hole is formed on the sliding member 2. The first limit position 12 and the second limit position 13 are two virtual positions on the extension path of the slide slot 11, and these two positions may be the ends of the slide slot 11 or not.
[0041] The rotating member is connected to the housing 1 in a rotational fit, and the position of the rotational fit connection is the first rotation center of the housing 1 in the circumferential direction. The rotating member is connected to the rotating shaft 4, and the rotating shaft 4 drives the rotating member to rotate counterclockwise / clockwise relative to the housing 1. The rotating member includes a rotating arm 3 and a spiral slide 5 connected to each other. The spiral slide 5 is inserted into the jack of the sliding member 2. The rotating arm 3 can be connected to the rotating shaft 4. The rotation of the rotating shaft 4 drives the rotating arm 3 and the spiral slide 5 to rotate. The circumferential direction of the rotating arm 3 is the circumferential direction formed around the second rotation center by taking the connection between the rotating arm 3 and the rotating shaft 4 (the center of the end face of the rotating shaft 4) as the second rotation center. The radial direction of the rotating arm 3 is the straight line direction along the diameter or radius with the second rotation center as the center. The sliding member 2 moves in the slide groove 11 under the drive of the spiral slide 5.
[0042] The scroll rail 5 is a rail structure extending along the scroll body profile line, and the scroll body profile line can be a logarithmic spiral, an equiangular spiral or an Archimedean spiral, etc. The rotating shaft 4 is directly or indirectly connected to the steering wheel, and the rotating shaft 4 can be an input shaft of the speed reduction mechanism.
[0043] The first limit position 12 and the second limit position 13 can be located at both ends of the slide groove 11, or can be located on the slide groove 11 near both ends of the slide groove 11. In order to reduce the volume of the housing 1, the first limit position 12 and the second limit position 13 can be set at both ends of the slide groove 11. When the sliding member 2 slides to the first limit position 12, the sliding member 2 forms a limit fit with one end of the slide groove 11. When the sliding member 2 slides to the second limit position 13, the sliding member 2 forms a limit fit with the other end of the slide groove 11. When the sliding member 2 forms a limit fit with both ends of the slide groove 11, the spiral slide rail 5 is restrained by the sliding member 2 and can no longer rotate in the original direction. Of course, the sliding member 2 can also form a limit fit with the rotating member.
[0044] The rotation angle limiting assembly provided in the embodiment of the present application is provided on the housing 1 with a slide groove 11 whose extension direction intersects with the tangential direction of the circumference of the housing 1 and a sliding member 2 slidably connected to the slide groove 11, and with an insertion hole on the sliding member 2 and a vortex ring spiral slide rail 5 passing through the insertion hole, so that the sliding member 2 can move between the first limit position 12 and the second limit position 13 in the slide groove 11 when the vortex ring spiral slide rail 5 rotates. The sliding member 2 forms a limiting fit with one end of the slide groove 11 or the rotating member when the sliding member 2 is in the first limit position 12, and forms a limiting fit with the other end of the slide groove 11 or the rotating member when the sliding member 2 is in the second limit position 13, so that the rotating member connected to the rotating shaft of the steering wheel cannot continue to rotate in the original direction.
[0045] In some embodiments, a first stop portion 31 and a second stop portion 32 are formed on the rotating member, and the first stop portion 31 and the second stop portion 32 are distributed at radial intervals along the rotating shaft 4, that is, the distance between the first stop portion and the rotation center of the rotating member and the distance between the second stop portion and the rotation center of the rotating member are not equal, the first stop portion 31 forms a limiting fit with the sliding member 2 at the first extreme position 12, and the second stop portion 32 forms a limiting fit with the sliding member 2 at the second extreme position 13.
[0046] The first stopper 31 and the second stopper 32 may be arranged on the rotating arm 3 or on the spiral rail 5 , or one of the first stopper 31 and the second stopper 32 may be arranged on the rotating arm 3 and the other may be arranged on the spiral rail 5 .
[0047] The sliding member 2 moves between the first extreme position 12 and the second extreme position 13. When the sliding member 2 moves to the first extreme position 12, the first stop portion 31 forms a limiting fit with the sliding member 2. When the sliding member 2 moves to the second extreme position 13, the second stop portion 32 forms a limiting fit with the sliding member 2.
[0048] refer to Figures 2 to 4 When the rotation angle limiting assembly provided in the embodiment of the present application is in use, the rotating shaft 4 drives the rotating member to rotate, and the spiral slide rail 5 drives the sliding member 2 to the first limit position 12 ( Figure 2 ) and the second extreme position 13 ( Figure 4 ) Figure 2 In the embodiment, the sliding member 2 is located at the first limit position 12, at which time the first stop portion 31 forms a limit fit with the sliding member 2, and the rotating shaft 4 cannot continue to rotate left. The rotating shaft 4 can only press Figure 2 The middle arc arrow turns right (clockwise), the rotating shaft 4 drives the rotating arm 3, the rotating arm 3 drives the spiral slide rail 5 to turn right, and the spiral slide rail 5 drives the sliding member 2 to rotate along Figure 2 Move in the direction of the straight arrow. Figure 3 The sliding member 2 slides to a position between the first limit position 12 and the second limit position 13. Until the sliding member 2 moves to the second limit position 13, as shown in FIG. Figure 4 As shown, at this time, the second stop portion 32 and the sliding member 2 form a limit fit at the second limit position 13. The rotating arm cannot continue to turn right, and the rotating arm starts to turn left (counterclockwise rotation, such as Figure 4 The rotating shaft 4 can only turn left, and the sliding member 2 rotates along the Figure 4 Move in the direction of the straight line arrow until the slide 2 moves to Figure 2 The first limit position 12 in the middle, and so on.
[0049] The first direction intersects with the tangent direction of the circumference of the housing 1 in two cases: there is an angle between the first direction and the radial direction of the housing 1 and the first direction coincides with the radial direction of the housing 1. Considering that the number of turns of the steering wheel is mostly an integer, in order to facilitate the design, the number of turns of the spiral guide rail 5 is exactly the integer number of turns of the steering wheel when the sliding member 2 moves from the first limit position 12 to the second limit position 13, such as Figures 1 to 6 As shown, the slide groove 11 extends in the radial direction of the housing 1, that is, the first direction intersects perpendicularly with the tangential direction of the circumference of the housing 1, that is, the first direction coincides with the radial direction of the housing 1. At the same time, the distance between the first stop portion 31 and the rotation center of the rotating member is not equal to the distance between the second stop portion 32 and the rotation center of the rotating member.
[0050] The number of turns of the spiral guide rail 5 between the first limit position 12 and the second limit position 13 determines the maximum number of turns that the steering wheel can turn left and right. Figures 2 to 4 In the embodiment of the present application, the number of revolutions of the rotating member and the rotating shaft 4 is three. By changing the number of revolutions of the spiral rail 5, the number of revolutions of the rotating shaft 4 can be changed, and the steering wheel rotation limit angles in different angle ranges can be achieved.
[0051] In specific implementation, the first stop portion 31 or the second stop portion 32 can be set on the spiral slide 5 (not shown in the figure), and the end of the spiral slide 5 forms a limiting portion, which forms a limiting fit with the socket on the sliding member 2, that is, the outer diameter of the limiting portion is larger than the inner diameter of the socket, so that the sliding member 2 can no longer have a tendency to move relative to the spiral path of the spiral slide 5.
[0052] The present application embodiment is described by assuming that the first stopper 31 and the second stopper 32 are arranged on the rotating arm 3. Figure 5 As shown, the first stopper 31 and the second stopper 32 are curved portions 36 formed on the rotating arm 3. The sliding member 2 forms a limit fit with the first stopper 31 and the second stopper 32 on opposite sides of the circumferential direction of the rotating shaft 4. The curved portions 36 are stamped out of the rotating arm 3, which is simple to process and low in cost. When the first stopper 31 and the second stopper 32 collide with the sliding member 2, the curved portions 36 can absorb the energy of the collision and reduce the sound of the collision.
[0053] In order to save costs and reduce the weight of the spiral slide rail 5, when the sliding member 2 is a cylinder, as shown in FIG. Figure 5 and Figure 8 As shown, the distance between the projection of the first stop portion 31 on the first plane and the projection of the second stop portion 32 on the first plane is L, the first plane is perpendicular to the radial direction of the rotating arm 3, and L is equal to the outer diameter of the sliding member 2. That is, Figure 2 and Figure 4As shown, along the circumference of the rotating shaft 4, the first stop portion 31 and the second stop portion 32 are respectively located on opposite sides of the sliding member 2 at two extreme positions, that is, when the first stop portion 31 abuts against one side of the sliding member 2, the line connecting the other side of the sliding member 2 and the rotation center of the rotating member passes through the second stop portion 32. This avoids unnecessary extension of the circumference of the spiral slide 5, avoids wasting the raw material of the spiral slide 5, and reduces the weight of the spiral slide 5.
[0054] Further, such as Figure 5 As shown, the rotating arm 3 is formed with a first connection portion 33 and a second connection portion 34 connected to the spiral slide rail 5. The first connection portion 33 is located on the side of the first stop portion 31 away from the second stop portion 32 in the circumferential direction, and the second connection portion 34 is located on the side of the second stop portion 32 away from the first stop portion 31 in the circumferential direction. That is, the first connection portion 33 is close to the first stop portion 31, and the second connection portion 34 is close to the second stop portion 32. The unnecessary extension circumference of the spiral slide rail 5 is avoided, the waste of the raw materials of the spiral slide rail 5 is avoided, and the weight of the spiral slide rail 5 is reduced. At the same time, the width of the rotating arm 3 in the circumferential direction is also reduced, and the weight of the rotating arm 3 is reduced. The overall weight of the angle limiting assembly is reduced. It is convenient to install the angle limiting assembly in the wire control steering system.
[0055] When implementing it specifically, Figure 5 and Figure 7 As shown, the two ends of the spiral slide 5 are respectively extended along the axial direction of the rotating shaft 4 to form a first connecting column 51 and a second connecting column 52. The first connecting column 51 and the second connecting column 52 can also be connected to the rotating arm 3 by bonding, welding or clamping. Considering that the spiral slide 5 is detachably connected to the rotating arm 3, it is convenient to replace the spiral slide 5. The first connecting portion 33 and the second connecting portion 34 can be through holes, and the first connecting column 51 is plugged into the first connecting portion 33, and the second connecting column 52 is plugged into the second connecting portion 34.
[0056] The first connecting column 51 and one end of the spiral slide 5 form a first avoidance space, and the avoidance space is used to accommodate the first stop portion 31. The second connecting column 52 and the other end of the spiral slide 5 form a second avoidance space, and the second avoidance space is used to accommodate the second stop portion 32. That is, one end of the spiral slide 5 directly bypasses the first stop portion 31 and then extends along the axial direction of the rotating shaft 4 to form the first connecting column 51, so as to avoid one end of the spiral slide 5 passing through the first stop portion 31, thereby increasing the difficulty of processing the rotating arm 3 and the difficulty of assembling the rotating arm 3 and the spiral slide 5.
[0057] like Figure 1 and Fig. 9As shown, the rotation angle limiting assembly further includes a cover 6, which covers the housing 1, and the rotating arm 3 and the spiral slide 5 are both located between the cover 6 and the housing 1. The cover 6 can limit the axial movement of the rotating member, so that the rotating arm 3 and the spiral slide 5 are connected firmly and compactly.
[0058] In another embodiment of the present application, a vehicle is provided, the vehicle includes the above-mentioned rotation angle limiting assembly, the rotating shaft 4 is inserted into the housing 1, and one end of the rotating shaft 4 is connected to the rotating arm 3. The rotating shaft 4 can be a spline shaft, and the rotating arm 3 is provided with a spline structure that cooperates with the spline shaft. Of course, the rotating shaft 4 and the rotating arm 3 can also be connected by means of clamping, bonding or shaft pin plugging. The rotating shaft 4 is directly or indirectly connected to the steering wheel. Reference Fig. 9 The housing 1 is connected to a component in a steering system of a vehicle, and the component may be a reducer housing 7. The housing 1 may be mounted on the reducer housing 7, or the housing 1 and the reducer housing 7 may be an integrally formed structure.
[0059] like Figure 5 As shown, a circular hole 35 is formed on the rotating arm 3, the rotating shaft 4 is inserted into the circular hole 35 and connected to the rotating arm 3, the first stopper 31 is located at the periphery of the circular hole 35 and is arranged close to the circular hole 35, and the second stopper 32 is located at the edge of the rotating arm 3. The rotating arm 3 is made as small as possible to reduce the weight of the rotating arm 3.
[0060] In the vehicle provided in the embodiment of the present application, when the turning angle limiting assembly is installed in the vehicle's steer-by-wire system, it can not only limit the rotation of the steering wheel, but also occupy less axial space of the rotating shaft 4 of the steer-by-wire system, thereby facilitating the arrangement of the steer-by-wire system in the whole vehicle environment.
