Description

Technical Field

[0001] The present invention relates to the field of vehicle technology, and in particular to a road feel simulator and a vehicle having the same. Background Art

[0002] Major OEMs are currently conducting preliminary research on steer-by-wire systems. Traditional steering systems have a mechanical connection between the steering wheel and the tires. When the user holds the steering wheel while getting in or out of the vehicle, the steering wheel is prevented from rotating due to friction between the tires and the ground. However, steer-by-wire systems eliminate the mechanical connection between the road simulator and the steering gear, instead using an intermediate shaft. This means the steering wheel will rotate when the user holds the steering wheel while getting in or out of the vehicle. This free rotation also creates an angle difference between the steering wheel and the wheel. Furthermore, since the two angles must be synchronized before driving, a large angle difference can lead to lengthy synchronization times, leading to user complaints. Prior to this, major OEMs installed a road simulator lock to prevent the steering wheel from rotating after the vehicle was powered off. However, adding this lock to the road simulator increases its size, hindering space planning, and also increases cost and weight. Summary of the Invention

In the accompanying drawings, for the sake of clarity, the thickness of layers and regions may be exaggerated, and the same reference numerals are used to represent the same devices, and thus their descriptions will be omitted.

[0033] Combine Figures 1 to 7 As shown, according to a specific embodiment of the present application, a road feel simulator is provided.

[0034] Specifically, a road feel simulator includes: a shell 10, the shell 10 has an accommodating cavity 101, a main shaft 20, part of the main shaft 20 is arranged in the accommodating cavity 101, the main shaft 20 is composed of an upper shaft 21 and a lower shaft 22, and the upper shaft 21 is provided with an external spline 221 at one end close to the lower shaft 22, wherein the upper shaft 21 and the lower shaft 22 are movably connected so that the main shaft 20 has a first working position in a welcome mode and a second working position in a vehicle starting mode; an anti-rotation component 30, the anti-rotation component 30 is sleeved on the lower shaft 22, and the anti-rotation component 30 is provided with an internal spline 300 that cooperates with the external spline 221; wherein, when the main shaft 20 is in the first working position, the internal spline 300 is engaged with the external spline 221 to prevent the main shaft 20 from rotating circumferentially, and when the main shaft 20 is in the second working position, the anti-rotation component 30 is away from the external spline 221 of the upper shaft 21.

[0035] In this embodiment, Figure 1 、 Figure 2 As shown, the housing 10 is sleeved on the main shaft 20, and the main shaft 20 is composed of an upper shaft 21 and a lower shaft 22. The upper shaft 21 is provided with an external spline 221 at one end near the lower shaft 22, wherein the upper shaft 21 and the lower shaft 22 are movably connected. The lower shaft 22 is also sleeved with an anti-rotation component 30, and the anti-rotation component 30 has an internal spline 300 with the same number of teeth as the external spline 221. The internal spline 300 engages with the external spline 221, thereby achieving anti-rotation at any steering wheel angle, effectively reducing the angle difference between the steering wheel angle and the wheel angle, and effectively reducing the size of the anti-rotation component, effectively improving space utilization. In this embodiment, the number of teeth on the internal spline is not limited, and it engages with the external spline with the same number of teeth. The external spline is press-fitted to the end of the main shaft 20, and the maximum anti-rotation torque of the inner ring of the external spline and the main shaft 20 can be set by controlling the tolerance ring.

[0036] Furthermore, the anti-rotation assembly 30 includes: a spline sleeve 31, the spline sleeve 31 is sleeved on the lower shaft 22, an internal spline 300 is provided at one end of the spline sleeve 31, and a first limiting ring 310 is provided at the other end of the spline sleeve 31; an annular base 32, the annular base 32 is provided with a second limiting ring 320 at one end facing the spline sleeve 31, the axial distance of the second limiting ring 320 is greater than the axial distance of the first limiting ring 310, a retaining ring 321 is provided on the end face of the other end of the annular base 32, the second limiting ring 320 is arranged along the circumference of the first limiting ring 310, and the second limiting ring 320 is located on the outside of the first limiting ring 310; an elastic member, there is at least one elastic member, and the elastic member is arranged between the second limiting ring 320 and the first limiting ring 310. In this embodiment, an elastic member is provided between the second limiting ring 320 and the first limiting ring 310 so that when the inner spline and the outer spline are aligned with each other, the inner spline and the outer spline can be quickly aligned and positioned when the steering wheel is rotated, thereby effectively preventing the steering wheel from rotating when the inner spline and the outer spline are aligned with each other.

[0037] Furthermore, a mounting hole 311 is provided on the end face of the spline sleeve 31, where the first retaining ring 310 is located. The mounting hole 311 is located outside the first retaining ring 310, and a portion of the elastic member is located within the mounting hole 311. This arrangement positions the elastic member, effectively preventing it from falling when the vehicle is in the second operating position in starting mode.

[0038] Specifically, the outer surface of the first retaining ring 310 is provided with a plurality of first relief grooves 3101, spaced apart along the circumference of the first retaining ring 310. Each first relief groove 3101 corresponds to a mounting hole 311. This arrangement allows the elastic member to be positioned through the mounting holes 311, and the one-to-one correspondence of the first relief grooves 3101 provides clearance for the elastic member. In this embodiment, the elastic member is a retaining spring 312.

[0039] Furthermore, the inner surface of the second retaining ring 320 is provided with a plurality of second escape grooves 3201, which correspond one-to-one with the plurality of first escape grooves 3101. Part of the elastic member is located within the escape channel formed between the first escape grooves 3101 and the corresponding second escape grooves 3201. In this embodiment, when the internal spline and the external spline are engaged, the first retaining ring 310 and the second retaining ring 320 are in contact with each other. At this time, the first escape grooves 3101 and the second escape grooves 3201 jointly provide an escape space for the elastic member.

[0040] like Figure 3As shown, at least one first limiting protrusion 313 is circumferentially provided on the spline sleeve 31, and at least one second limiting protrusion 322 is circumferentially provided on the annular base 32. The first limiting protrusion 313 and the second limiting protrusion 322 are arranged in a one-to-one correspondence. This arrangement allows the first limiting protrusion 313 and the second limiting protrusion 322 to jointly limit the anti-rotation assembly 30, effectively preventing the anti-rotation assembly 30 from automatically rotating or falling off during movement, effectively protecting the road feel simulator.

[0041] Furthermore, the housing 10 has an axial hole for mounting the main shaft 20. The wall of the axial hole is provided with at least one limiting groove 13, which extends along the axis of the axial hole and is used to accommodate a first limiting protrusion 313 and a second limiting protrusion 322. This arrangement prevents the anti-rotation assembly 30 from automatically rotating or falling off due to the action of the first limiting protrusion 313 and the second limiting protrusion 322 when the upper shaft 21 and the lower shaft 22 move, thereby preventing the internal and external splines from accurately engaging. In this embodiment, local reinforcement structures can be provided at the slots and holes of each component to prevent the structure from being too thin and having low strength. Furthermore, an appropriate amount of lubricant can be applied to the sliding mating areas to prevent dry grinding noise or damage to the internal and external splines.

[0042] Furthermore, a nylon sleeve is provided at the connection between the spline sleeve 31 and the external spline 221. A nylon sleeve is provided at the interface between the internal spline and the external spline to prevent metal collision sound when the two come into contact.

[0043] In another embodiment of the present application, a vehicle is provided, including a road feel simulator, which is the road feel simulator of the above-described embodiment. In this embodiment, the internal and external spline mounting methods can be threaded, splined, clamped, riveted, etc. Furthermore, the road feel simulator is mounted on the vehicle via a housing 10. The housing 10 is provided with several mounting holes 11 for mounting fasteners to the vehicle, and a fixed shaft 12, which serves as a rotation axis for adjusting the angle of the road feel simulator after installation.

[0044] Furthermore, the vehicle includes a welcome mode and a vehicle starting mode, wherein the main shaft 20 includes an upper shaft 21 and a lower shaft 22, the distance when the lower shaft 22 moves to the second working position is L1, and the distance when the lower shaft 22 moves to the first working position is L2, wherein L2>L1.

[0045] In this embodiment, when the user turns off the engine, the controller controls the road feel simulator to shorten to 50mm, and then further shortens it by Xmm to make the inner spline engage with the outer spline, thus preventing the steering wheel from rotating. The specific functions are as follows: When the vehicle is in the starting state, the driver can adjust the length of the road feel simulator through the road feel simulator adjustment button, such as Figure 5As shown in the figure, the normal adjustment range A is usually 50mm. The position adjustment of the road feel simulator by the driver through the button is only effective within this range.

[0046] When the driver turns off the engine and turns off the power, the vehicle welcome function starts. Figure 6 、 7 As shown, the road feel simulator drives the steering wheel to retract to the lowest position of the normal adjustment range A and then continues to retract by Xmm. This Xmm distance cannot be adjusted by the driver through the adjustment button and can only be adjusted by the road feel simulator controller when the welcome function is activated. Since the inner and outer spline teeth are not in the meshing position at this time, the inner and outer spline sleeves collide, and the outer spline pushes the inner spline to slide, causing the elastic member to compress until it reaches the road feel simulator adjustment stroke limit B position, that is, 50+Xmm position. Preferably, the elastic member compression limit position should be greater than the road feel simulator adjustment stroke limit B position, that is, when the road feel simulator adjustment stroke reaches 50+Xmm position, the elastic member still has compression space to prevent the elastic member from being compressed to the limit before the road feel simulator is adjusted to the limit position, causing the length adjustment motor to be unable to continue to push the main shaft 20 to move, causing the motor to stall. When the motor is stalled multiple times, it will cause permanent damage, so the spring compression limit position should be greater than the road feel simulator length adjustment stroke limit 50+Xmm position to protect the motor.

[0047] After the vehicle is powered off, the steering wheel is at any angle. When the driver gets on or off the vehicle and holds the steering wheel, the steering wheel rotates, and the rotation angle is less than 360° / number of spline teeth Y. After rotating a certain angle, the inner and outer splines reach the meshing position, and the spring will spring the outer spline to position C. Figure 7 As shown, the inner and outer splines are engaged to prevent the steering wheel from rotating.

[0048] When the driver restarts the vehicle, the vehicle welcome function is activated, and the road feel simulator controller adjusts the road feel simulator to extend to the length before the last engine shutdown and power off. At this time, the inner and outer splines are disengaged, and the driver can use the steering function normally.

[0049] In another embodiment of the present application, the road feel simulator is further provided with an angle adjustment mechanism 40 and a length adjustment mechanism 50. The angle adjustment mechanism 40 includes: an angle adjustment motor 41, an angle motor reduction mechanism 42, a connecting shaft 43, an angle adjustment slider 44, and an angle adjustment bracket 45. The length adjustment mechanism 50 includes a length adjustment motor 51, a length motor reduction mechanism 52, a screw 53, a length adjustment slider 54, a length adjustment bracket 55, and a pull-off piece 56. During length adjustment, the length adjustment motor 51 rotates forward or reverse, driving the screw 53 to rotate, and the length adjustment slider 54 slides back and forth relative to the screw 53, and drives the length adjustment bracket 55 to move. The length adjustment bracket 55 is connected to the pull-off piece 56 by screws, and the pull-off piece 56 is connected to the inner column tube 57 by screws. The inner column tube 57 moves and drives the main shaft 20 to move back and forth.
