DETAILED DESCRIPTION

[0035] The exemplary embodiments will be described in detail below with reference to the accompanying drawings. In the following description, the same numbers refer to the same elements throughout the drawings. The following exemplary embodiments described below are not meant to represent all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatuses and methods consistent with some aspects of the present disclosure as detailed in the appended claims.

The above definitions are only for the explanation and illustration of the present disclosure, and should not be understood as a limitation of the present disclosure. Figure 1

[0037] Firstly, it should be noted that the vehicle configured with the independent steering mechanism can allow each wheel to rotate independently, which makes the vehicle more flexible to adjust the steering angle of each wheel when turning, improves the understeer or oversteer phenomenon, and thus improves the handling and stability of the vehicle. Secondly, the vehicle configured with the independent steering mechanism can realize the same direction turning angle and the opposite direction turning angle of the front wheels and the rear wheels, which makes the wheels rotate in the same direction at high speed, improves the stability of the vehicle, and makes the vehicle rotate in the opposite direction at low speed, which is beneficial to reduce the turning radius of the vehicle, realizes the narrow road turning or U-turn, and makes the vehicle better adapt to more severe road conditions.

[0038] In addition, the vehicle configured with the independent steering mechanism can realize the same direction turning angle or the opposite direction turning angle of the left and right wheels, realize the U-turn or other use scenarios for specific working conditions. As can be seen, the vehicle configured with the independent steering mechanism can provide a more stable driving experience for the driver, and is expected to be more widely used in the field of automobiles. However, the stability of the rack in the current independent steering mechanism is poor, which affects the stability of the wheels during driving.

[0039] Based on the above, according to the exemplary embodiments of the present disclosure, with reference to the accompanying drawings, Figures 1 to 7 ​As shown in the independent steering mechanism, the independent steering mechanism comprises a housing 100, a steering structure 200, a pressing block 300 and a support 400. The steering structure 200 comprises a gear 1 and a rack 2 which are engaged with each other, and the rack 2 is slidably arranged in the housing 100. The pressing block 300 is used for pressing the rack 2 against the gear 1 and supporting the rack 2 in the up-down direction. The support 400 is arranged in the housing 100 and supports the rack 2 in the up-down direction. The support 400 and the pressing block 300 are arranged in the moving direction of the rack 2.

[0040] The technical scheme provided by the embodiments of the present disclosure can have the following beneficial effects: in the independent steering mechanism provided by the present disclosure, the pressing block 300 and the support 400 are arranged, the pressing block 300 is used for pressing the rack 2 against the gear 1 so that the rack 2 is fully engaged with the gear 1. Since the pressing block 300 and the support 400 both support the rack 2 in the up-down direction, and the support 400 and the pressing block 300 are arranged in the moving direction of the rack 2, the support of the rack 2 is improved by the cooperation of the pressing block 300 and the support 400 on both sides, which improves the stability of the rack 2 during movement, thereby reducing or even avoiding the swing of the wheels, so as to ensure the stability of the wheels during driving. In addition, compared with the support of the rack 2 on both sides by the support 400 only, the above arrangement can reduce the number of supports 400, so that the independent steering mechanism has fewer parts, thereby facilitating the simplified design of the independent steering mechanism.

[0041] In the present disclosure, reference is made to Figure 1 and Figure 2 The steering structure 200 can further comprise a driving motor 3, a speed reduction mechanism 4 and a controller 5. The gear 1 is in transmission connection with the driving motor 3 through the speed reduction mechanism 4. The driving motor 3 is in electrical connection with the controller 5. The rack 2 is connected with one end of a pull rod. The other end of the pull rod is connected with a steering knuckle connected with the vehicle. The connection mode between the rack 2, the pull rod and the steering knuckle is known to those skilled in the art, and will not be described in detail herein. The controller 5 is responsible for signal collection, processing and output. When the vehicle needs to be steered, the driver issues an instruction. After receiving the instruction, the controller 5 controls the driving motor 3 to work. The driving motor 3 drives the gear 1 to rotate through the speed reduction mechanism 4. The rotation of the gear 1 drives the rack 2 to elongate or contract, thereby pulling or pushing the pull rod. The pull rod drives the steering knuckle to deflect by pushing or pulling, wherein the speed reduction mechanism 4 can be a worm and gear mechanism, a ball screw mechanism or a T-shaped screw mechanism.

[0042] According to the example embodiment of the present disclosure, the speed reduction mechanism 4 can adopt a worm gear mechanism, the worm gear mechanism has smooth transmission and is not prone to generate vibration and noise, in addition, the worm gear mechanism can obtain a larger speed reduction ratio, and meanwhile, the worm gear mechanism has a small size and a compact structure, which is beneficial to reduce the occupied arrangement space, thereby being beneficial to increase the moving stroke of the rack 2.

[0043] According to the example embodiment of the present disclosure, referring to Figure 2 The support 400 can be connected at the end portion 20 of the rack 2 and synchronously moved with the rack 2 to form a sliding fit with the housing 100, as shown in

[0044] The support 400 and the end portion 20 of the rack 2 can adopt an interference fit to ensure the reliability of the connection between the support 400 and the rack 2, and the inner wall of the housing 100 and the support 400 can adopt a clearance fit to enable the support 400 to move along the housing 100.

[0045] The support 400 can be configured in any suitable structure, and two example embodiments of the support 400 will be described below.

[0046] According to the example embodiment of the present disclosure, referring to Figure 4 and Figure 5 The support 400 and the housing 100 can be provided with a plurality of rolling bodies 401, and the rolling bodies 401 are arranged around the circumference of the support 400, as shown in the above technical solutions, the rolling bodies 401 can be configured in a spherical shape, a cylindrical shape, or a conical shape, as long as the rolling bodies 401 can roll along the housing 100, which is not limited in the present disclosure, and the contact area is reduced by the rolling bodies 401, and the rolling contact reduces the friction, which is beneficial to improve the smoothness of the movement of the support 400 and the rack 2, ensure the movement accuracy of the rack 2, and thereby improve the steering accuracy of the wheel.

[0047] In the above example embodiment, referring to Figure 4 and Figure 5As shown in FIG. 1 and FIG. 2, the rolling body 401 is rollably connected to the support 400, and the housing 100 is provided with a sliding groove 101 extending along the moving direction of the rack 2, and the rolling body 401 is partially arranged in the sliding groove 101. The sliding groove 101 plays a guiding role, and ensures that the rolling body 401 rolls along the corresponding sliding groove 101, so that the support 400 drives the rack 2 to stably move, and ensures the stability of the rack 2 during movement, thereby ensuring the stability of the wheel steering.

[0048] In the above exemplary embodiments, with reference to Figure 4 and Figure 5 As shown in FIG. 1 and FIG. 2, the rolling body 401 can be configured as a ball. That is, the rolling body 401 is configured in a spherical structure, so that the rolling body 401 and the sliding groove 101 are in point contact, which reduces the contact area between the rolling body 401 and the sliding groove 101, thereby reducing the friction between the rolling body 401 and the sliding groove 101, and further ensuring the smoothness of the movement of the support 400 and the gear 1, which is conducive to improving the steering accuracy of the wheel. The diameter and number of the rolling body 401 can be set according to specific bearing requirements, and the present disclosure does not make specific limitations thereto.

[0049] According to another exemplary embodiment of the present disclosure, with reference to Figure 6 and Figure 7 As shown in FIG. 1 and FIG. 2, the support 400 can also be configured as a sliding bearing, which is sleeved on the end portion 20. By cooperating the pressing block 300 with the sliding bearing sleeved on the end portion 20 of the rack 2, both sides of the rack 2 are supported, the sliding bearing has strong bearing capacity and can reliably support the rack 2, the sliding bearing structure is relatively simple, and is easy to manufacture and process, and is convenient to disassemble and assemble. In addition, the service life of the sliding bearing is long, which is conducive to prolonging the service life of the independent steering mechanism of the present disclosure.

[0050] In the present disclosure, the cross section of the sliding bearing can be circular or other shapes, such as square, and the present disclosure does not make specific limitations thereto.

[0051] According to an exemplary embodiment of the present disclosure, with reference to Figure 6 and Figure 7 As shown in FIG. 1 and FIG. 2, the outer peripheral wall of the sliding bearing can be provided with a wear-resistant coating 402. The wear-resistant coating 402 can be a polytetrafluoroethylene (PTFE) coating, or other wear-resistant coating 402 with good wear resistance and good self-lubricating properties, and the present disclosure does not make specific limitations thereto. The wear-resistant coating 402 improves the wear resistance of the sliding bearing, and is conducive to reducing the friction coefficient of the sliding bearing.

[0052] According to an exemplary embodiment of the present disclosure, with reference to Figure 1 andFigure 2 As shown in FIG. 1, the independent steering mechanism can include two steering structures 200, the housing 100 is configured as an integrally formed piece, and the two racks 2 are independently and slidably arranged in the housing 100, and the pressure block 300 and the support 400 are supported on each rack 2. Among them, the two steering structures 200 can be left and right steering structures respectively, which are used to control the steering of the left and right wheels, and by slidably arranging the two racks 2 in the housing 100, that is, arranging the two steering structures 200 on the same housing 100.

[0053] Of course, referring to Figure 3 As shown in FIG. 1, the independent steering mechanism can include two steering structures 200, the housing 100 is configured as an integrally formed piece, and the two racks 2 are independently and slidably arranged in the housing 100, and the pressure block 300 and the support 400 are supported on each rack 2. Among them, the two steering structures 200 can be left and right steering structures respectively, which are used to control the steering of the left and right wheels, and by slidably arranging the two racks 2 in the housing 100, that is, arranging the two steering structures 200 on the same housing 100.

[0054] Compared with arranging the two steering structures 200 on different housings 100, the technical scheme of arranging the two steering structures 200 on the same housing 100 is adopted in the present disclosure, which is beneficial to reduce the arrangement space of the entire housing 100 in the width direction of the vehicle under the condition that the arrangement space in the width direction of the vehicle is fixed, thereby increasing the remaining space of the vehicle in the width direction, which is beneficial to increase the moving stroke of the rack 2, expand the rotation angle range of the wheel, realize a larger wheel rotation angle, and improve the compactness of the overall structure of the independent steering mechanism.

[0055] According to the exemplary embodiments of the present disclosure, referring to Figure 1 and Figure 2 As shown in FIG. 1, the independent steering mechanism includes two steering structures 200, and the housing 100 is provided with a receiving groove 102 extending along the extension direction of the vehicle axle, and the two racks 2 are independently and slidably arranged in the receiving groove 102. In this way, the two racks 2 can independently move along the extension direction of the same receiving groove 102 to adjust the rotation angle of the wheel, which is beneficial to improve the compactness of the structure, and referring to Figure 4 As shown in FIG. 1, the receiving groove 102 can be formed with a sliding groove 101 for partially arranging the rolling body 401 in the sliding groove 101.

[0056] According to the exemplary embodiments of the present disclosure, referring to Figure 2As shown in the figure, the shell 100 can have a spacing space formed between the two racks 2 in the middle part of the shell 100 and extending in the moving direction of the racks 2. That is, at the middle position of the shell 100, a spacing space is formed between the two racks 2, and because the two steering structures 200 are arranged on the same shell 100, the utilization space of the vehicle in the width direction is increased, that is, the space for arranging the two racks 2 is increased, so that the increased space can be used to set the spacing space, and specifically, part of the increased space can be used to increase the movement stroke of the two racks 2, and the remaining part of the increased space can be used to set the spacing space. The setting of the spacing space can reduce or even avoid the collision of the two racks 2 (i.e., the left rack 2 and the right rack 2), and improve the durability of the independent steering mechanism.

[0057] Based on the above, taking the maximum distance between the left rack outer end face and the right rack outer end face as 700mm~710mm, for example, 703mm, the two steering structures 200 are arranged on the integrally formed shell 100, and compared with arranging the two steering structures 200 on the separately arranged shell 100, the total stroke of the two racks 2 of the independent steering mechanism can be increased by 18mm~20mm.

[0058] On the basis of the above technical solutions, the present disclosure also provides a vehicle comprising the above independent steering mechanism. The vehicle provided by the present disclosure also has the above characteristics, and to avoid repetition, it will not be described here.

[0059] Reference Figures 8 to 11 As shown in the figure, the left and right racks of the independent steering mechanism of the embodiment of the present disclosure have the following four movement modes: first, the left and right racks move to the left, at this time the state of the left and right racks is as shown in Figure 8 The second, the left and right racks move to the right, at this time the state of the left and right racks is as shown in Figure 9 The third, the left and right racks move towards each other, that is, the left and right racks move closer to each other, at this time the distance between the left and right racks gradually decreases, and has a state as shown in Figure 10 The fourth, the left and right racks move away from each other, that is, the left and right racks move away from each other, or in other words, the distance between the left and right racks gradually increases, and has a state as shown in Figure 11 The fourth, the left and right racks move away from each other, that is, the left and right racks move away from each other, or in other words, the distance between the left and right racks gradually increases, and has a state as shown in
