Detailed Implementation

[0019] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein 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 accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0020] The following is for reference. Figures 1-6 This invention describes a steering drive 10 according to an embodiment of the present invention and a vehicle having the same.

[0021] like Figures 1-3 As shown, the steering drive 10 according to an embodiment of the present invention includes: a drive member 11, a transmission mechanism 2, a locking member 3, and a mating member 4. The transmission mechanism 2 is connected to the drive member 11, the mating member 4 is disposed on the transmission mechanism 2 or the drive member 11, the locking member 3 can lock the mating member 4 to lock the mating member 4, and the locking member 3 can unlock the mating member 4.

[0022] The drive component 11 can be configured as a motor, and the transmission mechanism 2 can be configured as a multi-stage reduction mechanism. The high speed and low torque transmitted from the drive component 11 to the transmission mechanism 2 can be converted into low speed and high torque through the multi-stage reduction mechanism. The transmission mechanism 2 can then transmit the low speed and high torque to the wheels to make the wheels turn.

[0023] The steering actuator 10 can be used to respond to the driver's steering needs. When the driver needs to steer the vehicle, the driver can turn the vehicle steering wheel. The steering wheel can be connected to a sensor. The sensor can sense the rotation angle and direction of the steering wheel and transmit the rotation angle and direction information of the steering wheel to the controller 12 in the form of a steering electrical signal. The controller 12 can receive and parse the steering electrical signal and control the drive unit 11 to work, so as to drive the steering actuator 10 to move. The steering actuator 10 can drive the wheels to turn, so as to achieve the effect of vehicle steering.

[0024] The mating part 4 can be constructed as a gear, worm, etc. The mating part 4 is provided on the transmission mechanism 2 or the driving part 11. As some embodiments of this application, the mating part 4 can be fixedly connected to the transmission mechanism 2 or the driving part 11. The mating part 4 can be welded, snapped, screwed, etc. to the transmission mechanism 2 or the driving part 11. The following explanation uses a gear as an example of the structure of the mating part 4. The locking part 3 can lock with the mating part 4. The locking part 3 may include a retractable stop. The controller 12 can control the stop to extend between two adjacent teeth of the mating part 4 (gear) to prevent the mating part 4 (gear) from rotating and to lock the mating part 4. Since the mating part 4 is fixedly connected to the transmission mechanism 2 or the drive component 11, the transmission mechanism 2 or the drive component 11 is locked at the same time, and the entire steering drive 10 is locked, thereby locking the direction of travel of the wheel so that the wheel does not turn and can travel in the original direction (e.g., straight direction). In short, when the vehicle does not need to turn, by locking the mating part 4, the wheel can not turn, so that it is not necessary to follow the feedback of the road surface to the wheel in real time and control the direction of travel of the wheel through the controller as in related technologies, thereby improving the convenience and stability of controlling the direction of travel of the wheel. Moreover, this setting has low control difficulty, saves energy, and improves the reliability of the steering drive 10.

[0025] Similarly, when it is necessary to unlock the mating part 4, the stop can be moved out of the space between two adjacent teeth of the mating part 4 (gear) by the controller 12. That is to say, the stop no longer restricts the rotation of the mating part 4, and the wheel can be turned by the controller 12 to change the direction of the vehicle.

[0026] In the above embodiment, the locking member 3 locks the mating member 4, thereby locking the transmission mechanism 2 or the drive member 11 that is fixedly connected to the mating member 4, thereby locking the direction of travel of the wheel so that the wheel does not turn and can travel in the original direction, thereby improving the convenience and stability of controlling the direction of travel of the wheel. In addition, this setting can also achieve the effects of reducing control difficulty and saving energy.

[0027] In some embodiments of this application, such as Figure 4 and Figure 5 As shown, the mating component 4 includes: a mating body 41 and multiple mating teeth 42. The multiple mating teeth 42 are all connected to the mating body 41. The multiple mating teeth 42 are arranged at intervals and around each other. The locking component 3 includes: a lock cylinder 31. The lock cylinder 31 can extend into any two mating teeth 42 to lock the mating component 4, and the lock cylinder 31 can move out from between two mating teeth 42 to unlock the mating component 4.

[0028] The mating body 41 can be constructed as a disc-shaped structure, with multiple mating teeth 42 arranged circumferentially around the mating body 41. Each of the multiple mating teeth 42 can be connected to the mating body 41, and the multiple mating teeth 42 can be evenly spaced. Among the multiple evenly spaced mating teeth 42, any two adjacent mating teeth 42 can define a locking space 43. The multiple mating teeth 42 can define multiple locking spaces 43. The lock cylinder 31 can extend into the locking space 43 between two mating teeth 42 to lock the mating component 4, lock the transmission mechanism 2 or the driving component 11, and thus lock the direction of travel of the wheel so that the wheel does not turn and can travel in the original direction (e.g., straight direction), thereby achieving the effect of controlling the direction of travel of the wheel. This setting makes locking and unlocking smooth and quick, and has a good locking effect and low failure rate. Correspondingly, the lock cylinder 31 can move out between the two mating teeth 42 to unlock the mating part 4. When it is necessary to unlock the mating part 4, the stop can be moved out of the space between two adjacent teeth of the mating part 4 by the controller 12. That is to say, the stop no longer restricts the rotation of the mating part 4, and the wheel steering can be controlled by the controller 12 to change the direction of vehicle travel.

[0029] In some embodiments of this application, such as Figure 3 and Figure 6 As shown, the steering drive 10 also includes a controller 12, and the locking member 3 also includes a housing 32, a coil 33, and an elastic member 34. The housing 32 defines a first receiving space 35, at least a portion of the lock cylinder 31, the coil 33, and the elastic member 34 are all received in the first receiving space 35. The elastic member 34 is connected to the lock cylinder 31. The controller 12 is communicatively connected to the locking member 3 and can energize the coil 33 to drive the elastic member 34 to actuate, so that the lock cylinder 31 locks or unlocks the mating member 4.

[0030] The outer casing 32 defines a first receiving space 35, in which at least a portion of the lock cylinder 31, the coil 33, and the elastic element 34 can be received. The elastic element 34 can be constructed as a spring (e.g., a coil spring), and can have two opposing ends. One end of the elastic element 34 can be connected to the bottom wall or side wall of the first receiving space 35 (e.g., by welding, snap-fitting, etc.), and the other end of the elastic element 34 can be connected to the end of the lock cylinder 31 near the elastic element 34 (e.g., by welding, snap-fitting, etc.).

[0031] Coil 33 can be wrapped around the outside of elastic member 34, coil 33 can be energized, and controller 12 can be communicatively connected to locking member 3 (e.g., wireless communication or electrical connection via wire). These are some embodiments of the present application, such as... Figure 3 As shown, the controller 12 can be electrically connected to the locking member 3 via the wiring harness 14.

[0032] The locking element 3 can be normally closed; when there is no low-voltage electrical signal, the lock cylinder 31 does not extend into the locking space 43. The controller 12 can energize the coil 33. When the coil 33 is energized, the magnetic force generated by the coil 33 can stretch the elastic element 34, causing the elastic element 34 to push the lock cylinder 31 towards the mating element 4 until the mating element 4 extends into any locking space 43, thus locking the mating element 4. Similarly, the controller 12 can de-energize the coil 33. When the coil 33 is not energized, the elastic element 34 retracts, pulling the lock cylinder 31 out from the corresponding locking space 43, thereby unlocking the mating element 4 so that the steering drive 10 can drive the wheels to steer.

[0033] As another embodiment of this application, the locking member 3 can be in a normally open mode. When there is no low voltage electrical signal, the lock cylinder 31 extends into the locking space 43. When it is necessary to unlock the mating member 4, the controller 12 can energize the coil 33. When the coil 33 is energized, the elastic member 34 retracts to pull the lock cylinder 31 out from the corresponding locking space 43, thereby achieving the effect of unlocking the mating member 4 so that the steering drive 10 can drive the wheels to turn.

[0034] In some embodiments of this application, such as Figure 5 and Figure 6 As shown, from the end of the lock cylinder 31 near the elastic member 34 to the end away from the elastic member 34, at least a portion of the diameter of the end of the lock cylinder 31 away from the elastic member 34 gradually decreases to form a guide surface 311.

[0035] The lock cylinder 31 can be constructed as a columnar structure. Along the axial direction of the lock cylinder 31, and from the end of the lock cylinder 31 near the elastic member 34 to the end away from the elastic member 34, at least a portion of the diameter of the end of the lock cylinder 31 away from the elastic member 34 can gradually decrease to form a guide surface 311. By providing the guide surface 311, the lock cylinder 31 can be easily inserted into the locking space 43, thereby improving the response speed when locking the mating member 4, and thus improving the reliability of the steering drive 10.

[0036] In some embodiments of this application, such as Figure 3 As shown, the transmission mechanism 2 is constructed as a reduction mechanism and includes: multiple transmission components 21, which are sequentially connected and driven along the power transmission path. One end of the transmission component 21 is connected to the drive component 11, and the mating component 4 is provided on any of the transmission components 21.

[0037] The number of transmission components 21 can be two, three, four, etc. Multiple transmission components 21 can be constructed as gears, worms, or worm wheels, etc. Transmission components 21 can also be constructed as a structure with a transmission gear mounted on a gear shaft. Multiple transmission components 21 can be sequentially connected to form a power transmission path. Along the power transmission path of the transmission mechanism 2, the transmission component 21 corresponding to the power input end of the transmission mechanism 2 can be connected to the driving component 11. The driving component 11 can transmit power to the transmission component 21 corresponding to the power input end. The transmission component 21 corresponding to the power output end of the transmission mechanism 2 is constructed as an output component 22. The mating component 4 can be provided on any transmission component 21. As some embodiments of this application, the mating component 4 can be fixedly connected to any transmission component 21. It can be reasonably set according to actual needs to improve the design flexibility of the transmission mechanism 2. Furthermore, by fixing the mating component 4 to any transmission component 21, it is convenient to install the mating component 4.

[0038] In some embodiments of this application, such as Figure 3 As shown, the transmission component 21 that mates with the mating component 4 is constructed as a mating transmission component 211. The mating transmission component 211 is constructed as a rod. The driving component 11 and the mating component 4 are respectively located at both ends of the rod and are directly connected to the rod.

[0039] Among them, the transmission component 21 that cooperates with the mating component 4 can be constructed as a mating transmission component 211. As some embodiments of this application, the transmission component 21 corresponding to the power input end of the transmission mechanism 2 can be constructed as a mating transmission component 211. The cooperating transmission component 211 can be constructed as a rod, and the cooperating transmission component 211 can have two opposing ends. The driving component 11 and the cooperating component 4 can be respectively located at the two ends of the rod and are directly connected to the rod. This arrangement is reasonable, allowing the driving component 11 to transmit power to the cooperating transmission component 211 from one end of the cooperating transmission component 211. When the locking component 3 does not lock the cooperating component 4, neither the cooperating component 4 nor the driving component 11 will hinder the rotation of the cooperating transmission component 211 to transmit power. Furthermore, the rod has a large cooperating position, and the cooperating position between the rod and the next transmission component 21 can be set according to the actual situation to make the spatial position of the rod and the next transmission component 21 more reasonable, which is conducive to improving design flexibility and space utilization. In addition, by constructing the cooperating transmission component 211 as a rod and having the driving component 11 and the cooperating component 4 respectively located at the two ends of the rod, the assembly of the driving component 11, the cooperating component 4, and the cooperating transmission component 211 is convenient.

[0040] In some embodiments of this application, such as Figure 2 and Figure 3As shown, the steering drive 10 further includes: a first housing 51 and a second housing 52. The first housing 51 is connected to the second housing 52 and defines a second receiving space 53. The second housing 52 defines a third receiving space 54 that communicates with the second receiving space 53. The transmission member 21 that cooperates with the mating member 4 is configured as a mating transmission member 211. At least a portion of the mating transmission member 211 and at least a portion of the mating member 4 are received in the second receiving space 53, and at least a portion of the remaining transmission members 21 are received in the third receiving space 54.

[0041] Among them, the transmission component 21 that cooperates with the mating component 4 can be constructed as a mating transmission component 211. As some embodiments of this application, the transmission component 21 corresponding to the power input end of the transmission mechanism 2 can be constructed as a mating transmission component 211.

[0042] The first housing 51 can be connected to the second housing 52. As some embodiments of this application, the first housing 51 and the second housing 52 can be integrally formed. The first housing 51 can define a second receiving space 53, in which at least a portion of the cooperating transmission member 211 and at least a portion of the cooperating member 4 can be received. The second housing 52 can define a third receiving space 54 communicating with the second receiving space 53, in which at least a portion of the remaining transmission members 21 (the remaining portion of the remaining transmission members 21 can be understood as at least a portion of some of the remaining transmission members 21, or at least a portion of all of the remaining transmission members 21) can be received in the third receiving space 54. By setting the first housing 51 and the second housing 52, it is convenient to install the relevant components in the preset position of the steering drive 10. The first housing 51 and the second housing 52 can protect the relevant components located inside them. In addition, the mating transmission member 211 and the mating member 4 can be separated from the other transmission members 21 to reduce the risk of mutual interference. Furthermore, by connecting the second receiving space 53 and the third receiving space 54, it is convenient to connect the mating transmission member 211 with the next-level transmission member 21.

[0043] In some embodiments of this application, such as Figure 2 As shown, the steering drive 10 also includes: a cover 13, one end of the first housing 51 is open to form an open end 511 along the axial direction of the mating transmission member 211, the mating member 4 is located at the open end 511, and the cover 13 is detachably connected to the first housing 51 and covers the open end 511.

[0044] The transmission component 211 can be constructed as a rod (e.g., a worm gear). Along the axial direction of the transmission component 211, one end of the first housing 51 can be opened to form an open end 511. The mating component 4 can be inserted into the second receiving space 53 through the open end 511 and is located at the open end 511. The cover 13 can be detachably connected to the first housing 51, and the cover 13 can cover the open end 511 to facilitate disassembly of the cover 13 for maintenance of the mating component 4. Furthermore, the cover 13 can protect the mating component 4, reducing the risk of external interference affecting its normal operation or even causing damage. As some embodiments of this application, the cover 13 can be screwed or snapped onto the first housing 51 to reduce the difficulty of disassembly and assembly.

[0045] In some embodiments of this application, such as Figure 2 and Figure 3 As shown, at least a portion of the locking member 3 is housed in the second receiving space 53. The locking member 3 is parallel to the axial direction of the cooperating transmission member 211, and the locking member 3 and the cooperating transmission member 211 are arranged in a direction perpendicular to the axial direction of the cooperating transmission member 211.

[0046] At least a portion of the locking member 3 can be housed in the second receiving space 53 to protect the locking member 3 through the first housing 51. The locking member 3 can be arranged with the mating transmission member 211 in a direction perpendicular to the axial direction of the mating transmission member 211 to make full use of space, and the locking member 3 can be parallel to the axial direction of the mating transmission member 211 to make the steering drive 10 structure compact, thereby further improving space utilization. This arrangement can make the process of locking the mating member 4 by the locking member 3 smoother and improve the response effect of the locking member 3.

[0047] The vehicle according to the embodiments of this application includes a steering drive 10 and wheel hubs. The steering drive 10 is the same as the steering drive 10 in the above embodiments. The number of steering drives 10 and wheel hubs are the same and correspond one-to-one. The steering drive 10 is used to drive the corresponding wheel hub to rotate.

[0048] The system can include multiple steering actuators 10 and wheel hubs, with the number of each being identical and corresponding one-to-one. Each steering actuator 10 can be connected to the wheel hub via a drive mechanism (direct drive or indirect drive through components such as steering knuckles). The steering actuator 10 drives the corresponding wheel hub to rotate, thereby steering the wheel and achieving vehicle steering. Furthermore, by locking the locking member 3 to the mating member 4, the transmission mechanism 2 or drive member 11 fixed to the mating member 4 is locked, thus locking the wheel's direction of travel. This prevents the wheel from turning and allows it to travel in its original direction, improving the convenience and stability of controlling the wheel's direction of travel. This design also reduces control difficulty and saves energy.
