DETAILED DESCRIPTION

[0078] To make the objectives, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings herein can be arranged and designed in various different configurations.

[0079] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are intended to fall within the scope of protection of the present invention.

[0080] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0081] In the description of the present invention, it should be noted that if the terms "upper", "lower", "inside", "outside", etc. appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the accompanying drawings, or is the orientation or position relationship in which the product of the invention is usually placed when in use. It is only for the convenience of describing the present invention and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be understood as a limitation on the present invention.

[0082] In addition, the terms "first", "second", etc., if used, are merely used to distinguish and describe, and should not be understood as indicating or implying relative importance.

[0083] It should be noted that, in the absence of conflict, the features in the embodiments of the present invention may be combined with each other.

[0084] As described in the background, there are various types of shifting devices for unmanned vehicles in the prior art. Some shifting devices can switch between power and neutral gears, that is, switching from D gear to N gear, or vice versa. When an unmanned vehicle needs to have a parking function, a separate parking gear is generally set. For example, the prior art uses a ratchet cable parking method, but because this method requires separate gear settings, it results in scattered gear positions and poor integration. Alternatively, an electronic parking system is used, but this has the problems of high power consumption and severe heat generation.

[0085] In view of this, please refer to Figures 1-10 This embodiment provides a shifting device 100, a power steering system 1000, and a mobile device 1, which can effectively alleviate the aforementioned technical issues. The shifting device 100 can switch between park, power, and neutral gears, and has a high level of integration. This shifting device 100 can also be referred to as an NPD shifting device, where N represents neutral, P represents park, and D represents power.

[0086] The following will be combined Figure 1 The walking device 1 provided in this embodiment is described in detail.

[0087] Please refer to Figure 1 This embodiment provides a walking device 1, which includes a frame 2000, a walking device 3000 and a power control system 1000; wherein, the power control system 1000 is arranged on the frame 2000, and the walking devices 3000 are arranged on both sides of the frame 2000, and the power control system 1000 is used to drive the walking device 3000.

[0088] Combine Figure 1In this embodiment, the walking device 1 is an unmanned vehicle, specifically an agricultural unmanned vehicle. It is understandable that it is generally equipped with various actuators required for agriculture, such as spraying devices and sowing devices, which can realize spray irrigation, sowing, etc. Of course, it can also be used in other fields such as spraying fire extinguishing fluid during forest fires, sowing seeds, aerial photography, power inspections, environmental monitoring, forest fire prevention and disaster inspections. Alternatively, it can be equipped with gaming equipment for interaction. In this embodiment, the unmanned vehicle cannot carry passengers. It operates automatically according to a preset path and speed, or it can be manually controlled by an operator. In other embodiments, when the design meets the requirements, it can also carry a driver, and the relevant operations can be manually performed by the driver in the cab. That is, in other embodiments, it can also be a manned car. Of course, the walking device 1 can also be an agricultural robot. Therefore, the specific type of walking device 1 is not limited.

[0089] Please refer to Figure 2 , Figure 2 exist Figure 1 Based on the above, some structures are omitted, such as the walking device 3000. Figure 2 In the embodiment, the vehicle frame 2000 includes a plurality of cross beams 2100 and a plurality of longitudinal beams 2200. The plurality of cross beams 2100 are arranged between two adjacent longitudinal beams 2200. Specifically, the number of the cross beams 2100 is two, and the number of the longitudinal beams 2200 is two. Of course, in other embodiments, the number of the cross beams 2100 and the longitudinal beams 2200 can be three, four, five or more.

[0090] Figure 2 The aforementioned power steering system 1000 includes a power source 200 and a shifting device 100. Both the power source 200 and the shifting device 100 are mounted on the vehicle frame 2000. Specifically, the power source 200 is disposed between two adjacent crossbeams 2100 and between two adjacent longitudinal beams 2200. That is, the power source 200 is enclosed by the two crossbeams 2100 and the two longitudinal beams 2200, thereby effectively protecting the power source 200. The power source 200 is used to drive the traveling device 3000. Since the power source 200 is provided with a parking actuator 60 and a neutral actuator 70, the shifting device 100 can control the power source 200 so that the traveling device 1 is in the parking gear, the power gear, and the neutral gear.

[0091] (This control method is described in detail below)

[0092] In this embodiment, there are multiple power sources 200, at least one power source 200 is used to drive all running devices 3000 located on one side of the vehicle frame 2000, and at least one power source 200 is used to drive all running devices 3000 located on the other side of the vehicle frame 2000. Specifically, there are four running devices 3000, with two running devices 3000 distributed on both sides of the vehicle frame 2000. There are two power sources 200, one of which is used to drive the two running devices 3000 located on one side of the vehicle frame 2000, and the other power source 200 is used to drive the two running devices 3000 located on the other side of the vehicle frame 2000.

[0093] Please refer to Figure 3 , Figure 3 The power steering system 1000 mentioned above will be described. The power steering system 1000 includes a shift device 100 and a power source 200.

[0094] The shifting device 100 includes a carrier 10 , a parking control mechanism 20 , a parking actuator 60 , a neutral control mechanism 30 , a neutral actuator 70 , and an operating element 40 .

[0095] Combine Figure 2 The carrier 10 is mounted on the crossbeam 2100 or the longitudinal beam 2200. In this embodiment, the carrier 10 is positioned horizontally between two adjacent longitudinal beams 2200, with both ends of the carrier 10 secured to the two longitudinal beams 2200. In this embodiment, the operating member 40 is mounted on the carrier 10, and the carrier 10 is positioned behind the vehicle frame 2000. In other words, the operator typically performs the corresponding gear shifting operation using the operating member 40 from behind the vehicle. Of course, in other embodiments, the carrier 10 may also be positioned to the side of the vehicle frame 2000.

[0096] Specifically, the carrier 10 includes a plate 11, a parking box 12, and a neutral box 13. The parking box 12 and the neutral box 13 are spaced apart from the plate 11. The ends of the plate 11 are respectively fixed to the two longitudinal beams 2200. Partial components of the parking control mechanism 20 are disposed in the parking box 12, and partial components of the neutral control mechanism 30 are disposed in the neutral box 13.

[0097] The parking control mechanism 20 is connected to the parking actuator 60, thereby enabling the parking actuator 60 to be operated. At the same time, the parking actuator 60 is provided on the power source 200. The parking actuator 60 can realize the switching between the parking gear and the power gear. (The specific switching operation is detailed below)

[0098] The neutral operating mechanism 30 is connected to the neutral actuator 70, thereby operating the neutral actuator 70. The neutral actuator 70 is also located on the power source 200. This neutral actuator 70 enables switching between power and neutral gears. Specifically, the power source 200 includes a power motor 210, a transmission component 220, and a neutral switch 230. The transmission component 220 is connected to the power motor 210, and the neutral switch 230 is located on the power motor 210. The neutral switch 230 is used to control whether the power motor 210 and the transmission component 220 are in a power transmission state or a power release state. It will be understood that the neutral actuator 70 is located at the neutral switch 230. By triggering or deactivating the neutral switch 230, power release or power transmission can be achieved. When the neutral switch 230 is deactivated, power from the power motor 210 can be transmitted to the transmission component 220, which then transmits power to the running device 3000. When the neutral switch 230 is triggered, the power of the power motor 210 cannot be transmitted to the transmission component 220. At this time, even if the power motor 210 is in the state of being powered, it can only idle. (The specific triggering operation is detailed below)

[0099] Combine Figure 3 For each power source 200, a parking actuator 60 and a neutral actuator 70 are distributed at opposite ends of the power source 200. It can be understood that the parking actuator 60 and the neutral actuator 70 are respectively arranged at both ends of the power motor 210, so that relatively speaking, there will be no interference between the two.

[0100] Please refer to Figure 4 , Figure 4 exist Figure 3 Based on the omission of some structures, such as omitting the power source 200, combined Figure 3 and Figure 4 Since there are multiple power sources 200 in this embodiment, for example, two, in order to simultaneously control all power sources 200, the number of parking actuators 60 and neutral actuators 70 matches the number of power sources 200. For example, each power source 200 is assigned one parking actuator 60 and one neutral actuator 70. Furthermore, all parking actuators 60 are operated by one parking operating mechanism 20, for example, by the relevant components within the parking box 12. All neutral actuators 70 are operated by one neutral operating mechanism 30, for example, by the relevant components within the neutral box 13. In other words, by operating the relevant components within the parking box 12 through the operating member 40, all parking actuators 60 can be actuated, and by operating the relevant components within the neutral box 13 through the operating member 40, all neutral actuators 70 can be actuated.

[0101] Please refer to Figure 5 , Figure 5 This can help understand the shifting method of the shifting device 100 . Specifically, in this embodiment, the carrier 10 is provided with a shifting groove 110 . Specifically, the shifting groove 110 is opened on the plate 11 .

[0102] The shift slot 110 has an auxiliary position 111, a first position 112, a second position 113, a third position 114, and a fourth position 115, which are arranged in this order. The auxiliary position 111 and the first position 112 are arranged in a left-right direction, the first position 112 and the second position 113 are arranged in a bottom-up direction, the second position 113 and the third position 114 are arranged in a left-right direction, and the third position 114 and the fourth position 115 are arranged in a top-bottom direction. The directions "up," "down," "left," and "right" mentioned herein can be understood as relative positions when the device is normally placed, or relative positions understood by those skilled in the art.

[0103] The operating member 40 is movably engaged with the shift slot 110; the operating member 40 is used to lock the shift device 100 in the parking gear when it is in the auxiliary position 111, to release the locked state and maintain the parking gear when switching from the auxiliary position 111 to the first position 112, to toggle the first toggle member 21 to switch the parking gear to the power gear when switching from the first position 112 to the second position 113, to maintain the power gear when switching from the second position 113 to the third position 114, and to toggle the second toggle member 31 to switch the power gear to the neutral gear when switching from the third position 114 to the fourth position 115.

[0104] Combine Figure 5 It can be understood that the shift slot 110 is an inverted U-shape as a whole. When the operating member 40 is in the auxiliary position 111, the first position 112, or between the auxiliary position 111 and the first position 112, the shift device 100 is in the parking gear (P). When the operating member 40 is in the first position 112 and the second position 113, the gear position changes. When the operating member 40 is in the second position 113, the third position 114, or between the second position 113 and the third position 114, the shift device 100 is in the power gear (D). When the operating member 40 is in the third position 114 and the fourth position 115, the gear position changes. When the operating member 40 is in the fourth position 115, the shift device 100 is in the neutral gear (N). Of course, it is not ruled out that in a specific implementation, the shift slot 110 is an inverted U-shape as a whole.

[0105] It should be noted that the auxiliary position 111 is not necessary, that is, in a certain embodiment, the auxiliary position 111 may not be provided.

[0106] Please refer to Figure 6 , and combined with Figure 5 In this embodiment, the operating member 40 includes a handle 41 and an operating portion 42. The operating portion 42 is arranged at one end of the handle 41. The handle 41 is movably arranged in the shift slot 110. The operating portion 42 is used to operate the parking operating mechanism 20 and the neutral operating mechanism 30.

[0107] Please refer to Figure 7 , Figure 7 exist Figure 6 On the basis of omitting some structures, such as omitting part of the shell of the parking box 12, in order to better understand the relevant components inside it, combined with Figure 7 and Figure 6 The parking operating mechanism 20 includes a first toggle member 21 and a first flexible body 22. One end of the first flexible body 22 is connected to the first toggle member 21, and the other end of the first flexible body 22 is used to connect to the parking actuator 60; the first toggle member 21 is movably arranged on the carrier 10, and is used to operate the parking actuator 60 through the first flexible body 22 when it is toggled.

[0108] The first flexible body 22 can optionally be a steel wire rope, a cable, a rope, a chain, a gooseneck, etc., or a plurality of universal joints connected in sequence. Compared with a rigid structure, this flexible structure has a certain degree of softness and can bypass various devices mounted on the frame 2000. At the same time, it can effectively manipulate components far away from the first shift member 21, that is, the length of the first flexible body 22 can be longer.

[0109] Specifically, the first shifting member 21 is connected to the housing of the parking box 12 , and can be actuated by the shifting member 40 , thereby operating the parking actuator 60 .

[0110] Combine Figure 7 To prevent unexpected shift changes of the operating member 40 after a gear shift, in this embodiment, the parking control mechanism 20 further includes a first elastic retaining member 23. The first elastic retaining member 23 is disposed on the first toggle member 21 and acts on the carrier 10. The first elastic retaining member 23 is used to maintain the position of the first toggle member 21 through elastic force. In other words, when the shifting device 100 is in the parking gear, the power gear, or the neutral gear, the first elastic retaining member 23 maintains the position of the first toggle member 21, thereby maintaining the state of the parking actuator 60 it controls.

[0111] Of course, in some embodiments, the first elastic retaining member 23 may not be provided, and instead a greater damping may be provided for the movement of the first toggle member 21, which can also achieve the corresponding effect. Furthermore, it is also possible to consider providing the aforementioned shift slot 110 and handle 41 with an interference fit, that is, the handle 41 requires a greater force to slide within the shift slot 110. In this way, when the handle 41 is in a certain position, it will remain in that position unless a strong force is applied, thereby avoiding sudden shifts in gear.

[0112] Combine Figure 7 In this embodiment, the first shifting member 21 is rotatably disposed on the carrier 10 to switch between the parking position and the first power position. The rotation direction is shown by the arrow.

[0113] One end of the first elastic retaining member 23 is arranged on the carrier 10 (specifically the parking box 12), and the other end of the first elastic retaining member 23 is connected to the eccentric position of the first toggle member 21; the first toggle member 21 is used to loosen the first flexible body 22 when it is in the parking position, so that the shifting device 100 is in the parking gear, and the first toggle member 21 is used to tighten the first flexible body 22 when it is in the first power position, so that the shifting device 100 is in the power gear.

[0114] When the first toggle member 21 is in the parking position, the first elastic retaining member 23 is used to maintain the first toggle member 21 in the parking position through an eccentrically directed elastic force. When the first toggle member 21 is in the first power position, the first elastic retaining member 23 is used to maintain the first toggle member 21 in the first power position through an eccentrically directed elastic force. In other words, the eccentrically directed force can maintain the first toggle member 21 in its position. In other words, after the operating member 40 is disengaged from the first toggle member 21, the eccentrically directed force provided by the first elastic retaining member 23 can reversely lock the first toggle member 21. In other words, a large sudden force is required to actuate the first toggle member 21.

[0115] In the above description, the first shifting member 21 is rotated relative to the axis of rotation of the carrier 10 (specifically the parking box 12) by Figure 7 The dotted line in FIG shows that the eccentric force mentioned above can be understood as the direction of the force being not coplanar with the rotation axis. Similarly, the eccentric position of the first toggle member 21 can be understood as the position being a certain distance away from the rotation axis, that is, not on the rotation axis.

[0116] In this embodiment, specifically, the first elastic retaining member 23 includes a first retaining rod 231 and a first elastic member 232. A first retaining mounting portion 213 is provided at an eccentric position of the first toggle member 21. One end of the first retaining rod 231 is hinged to the first retaining mounting portion 213, and the other end of the first retaining rod 231 is movably connected to the carrier 10. The first elastic member 232 is provided on the first retaining rod 231 and acts on both the first toggle member 21 and the carrier 10, thereby applying an elastic force to the first toggle member 21. Of course, in other embodiments, when the first retaining rod 231 itself has a relatively high elasticity, the first elastic member 232 may be omitted. In other words, the first toggle member 21 can maintain its position under the elastic action of the first retaining rod 231.

[0117] In this embodiment, in order to facilitate the relative movement between the first retaining rod 231 and the carrier 10, the carrier 10 is provided with a first limiting hole 121, and the first retaining rod 231 is movably inserted into the first limiting hole 121. Specifically, the first limiting hole 121 is provided on the parking box 12.

[0118] At the same time, in order to facilitate the installation of the first elastic member 232, in this embodiment, the first elastic member 232 is a spring, the first elastic member 232 is mounted on the first retaining rod 231, and one end of the first elastic member 232 is against the first toggle member 21, and the other end of the first elastic member 232 is against the carrier 10.

[0119] When the first toggle member 21 is in the parking position, the first elastic member 232 is generally in a natural state. In other words, when the operating member 40 toggles the first toggle member 21 to rotate, the applied force needs to overcome the elastic force of the first elastic member 232. At this time, the first retaining rod 231 will move within the first limiting hole 121. When the first toggle member 21 rotates to the first power position, the first elastic member 232 is also in a natural state. Therefore, whether the first toggle member 21 is in the parking position or the first power position, the first elastic member 232 can provide an elastic force, so it can maintain its current position.

[0120] In light of the above, since the first actuator 21 in a parking box 12 needs to operate two parking actuators 60, in this embodiment, at least one parking mounting portion 212 is provided at an eccentric position of the first actuator 21, thereby being assembled with at least one first flexible body 22. It will be understood that since there are multiple power sources 200 and multiple parking actuators 60, there are also multiple first flexible bodies 22, and they correspond one-to-one with each power source 200. Specifically, there are two parking mounting portions 212, which are assembled with one end of the two first flexible bodies 22, while the other ends of the two first flexible bodies 22 are respectively assembled with the two parking actuators 60.

[0121] To facilitate the manipulation of the first toggle member 21 by the manipulation member 40, in this embodiment, the first toggle member 21 is provided with a first toggle portion 211, which is configured to engage with the manipulation member 40 and thereby be toggled by the manipulation member 40. Specifically, the first toggle portion 211 is a cylindrical structure with a notch, and one side of the manipulation portion 42 of the manipulation member 40 is also a cylindrical structure with a notch. Thus, the engagement of the two cylindrical structures enables the first toggle member 21 to be toggled by the manipulation member 40.

[0122] Please refer to Figure 8 , Figure 8 exist Figure 6 On the basis of omitting some structures, such as omitting part of the housing of the neutral box 13, in order to better understand the relevant components inside it, combined with Figure 8 and Figure 6 The neutral gear operating mechanism 30 includes a second toggle member 31 and a second flexible body 32. One end of the second flexible body 32 is connected to the second toggle member 31, and the other end of the second flexible body 32 is used to connect to the neutral gear actuator 70; the second toggle member 31 is movably arranged on the carrier 10, and is used to operate the neutral gear actuator 70 through the second flexible body 32 when it is toggled.

[0123] The second flexible body 32 can optionally be a steel wire rope, a cable, a rope, a chain, a gooseneck, etc., or a plurality of universal joints connected in sequence. Compared with a rigid structure, this flexible structure has a certain degree of softness and can bypass various devices mounted on the frame 2000. At the same time, it can effectively manipulate components far away from the second shift member 31, that is, the length of the second flexible body 32 can be longer.

[0124] Specifically, the second shifting member 31 is connected to the housing of the neutral gear box 13 , and can be actuated by the shifting of the operating member 40 , thereby operating the neutral gear actuator 70 .

[0125] Combine Figure 8 To prevent unexpected shift changes of the operating member 40 after a gear shift, in this embodiment, the neutral operating mechanism 30 further includes a second elastic retaining member 33. The second elastic retaining member 33 is disposed on the second toggle member 31 and acts on the carrier 10. The second elastic retaining member 33 is used to maintain the position of the second toggle member 31 through elastic force. In other words, when the shifting device 100 is in the parking gear, the power gear, or the neutral gear, the second elastic retaining member 33 maintains the position of the second toggle member 31, thereby maintaining the state of the neutral actuator 70 it controls.

[0126] Of course, in some embodiments, the second elastic retaining member 33 may not be provided, and instead a greater damping may be provided for the movement of the second toggle member 31, which can also achieve the corresponding effect. Furthermore, it is also possible to consider providing the aforementioned shift slot 110 and handle 41 with an interference fit, that is, the handle 41 requires a greater force to slide within the shift slot 110. In this way, when the handle 41 is in a certain position, it will remain in that position unless a strong force is applied, thus avoiding sudden shifts in gear.

[0127] Combine Figure 8 In this embodiment, the second shifting member 31 is rotatably disposed on the carrier 10 to switch between the neutral position and the second power position. The rotation direction is shown by the arrow.

[0128] One end of the second elastic retaining member 33 is arranged on the carrier 10 (specifically, the neutral gear box 13), and the other end of the second elastic retaining member 33 is connected to the eccentric position of the second toggle member 31; the second toggle member 31 is used to tighten the second flexible body 32 when it is in the neutral position, so that the shifting device 100 is in neutral gear, and the second toggle member 31 is used to loosen the second flexible body 32 when it is in the second power position, so that the shifting device 100 is in power gear.

[0129] When the second toggle member 31 is in the neutral position, the second elastic retaining member 33 is used to maintain the second toggle member 31 in the neutral position through an eccentrically directed elastic force. When the second toggle member 31 is in the second powered position, the second elastic retaining member 33 is used to maintain the second toggle member 31 in the second powered position through an eccentrically directed elastic force. In other words, after the operating member 40 is released from the second toggle member 31, the eccentrically directed force provided by the second elastic retaining member 33 will reversely lock the second toggle member 31. In other words, a large sudden force is required to actuate the second toggle member 31.

[0130] In the above description, the second shifting member 31 is located at a position relative to the rotation axis of the carrier 10 (specifically the neutral box 13). Figure 8 The dotted line in FIG shows that the eccentric force mentioned above can be understood as the direction of the force being not coplanar with the axis of rotation. Similarly, the eccentric position of the second toggle member 31 can be understood as the position being a certain distance away from the axis of rotation, that is, not on the axis of rotation.

[0131] In this embodiment, specifically, the second elastic retaining member 33 includes a second retaining rod 331 and a second elastic member 332. A second retaining mounting portion 313 is provided at an eccentric position of the second toggle member 31. One end of the second retaining rod 331 is hinged to the second retaining mounting portion 313. The other end of the second retaining rod 331 is movably connected to the carrier 10. The second elastic member 332 is provided on the second retaining rod 331 and acts on the second toggle member 31 and the carrier 10 at the same time, thereby applying elastic force to the second toggle member 31.

[0132] In this embodiment, since the shift groove 110 is in an inverted U-shape as a whole, in order to adapt to this design, the first retaining rod 231 and the second retaining rod 331 are arranged at an angle.

[0133] Of course, in other embodiments, when the second retaining rod 331 itself has greater elasticity, the second elastic member 332 can also be omitted. In other words, the second shifting member 31 can maintain its position under the elastic action of the second retaining rod 331.

[0134] In this embodiment, in order to facilitate the relative movement between the second holding rod 331 and the carrier 10, the carrier 10 is provided with a second limiting hole 131, and the second holding rod 331 is movably inserted into the second limiting hole 131. Specifically, the second limiting hole 131 is provided on the neutral box 13.

[0135] At the same time, in order to facilitate the installation of the second elastic member 332, in this embodiment, the second elastic member 332 is a spring, the second elastic member 332 is mounted on the second retaining rod 331, and one end of the second elastic member 332 is against the second toggle member 31, and the other end of the second elastic member 332 is against the carrier 10.

[0136] When the second toggle member 31 is in the neutral position, the second elastic member 332 is generally in a natural state. In other words, when the operating member 40 toggles the second toggle member 31 to rotate, the applied force needs to overcome the elastic force of the second elastic member 332. At this time, the second retaining rod 331 will move within the second limiting hole 131. When the second toggle member 31 rotates to the second powered position, the second elastic member 332 is also in a natural state. Therefore, whether the second toggle member 31 is in the neutral position or the second powered position, the second elastic member 332 can provide an elastic force, so it can maintain its current position.

[0137] In light of the above, since the second toggle member 31 in one neutral gear box 13 needs to operate two neutral gear actuators 70, in this embodiment, at least one neutral gear mounting portion 312 is provided at an eccentric position of the second toggle member 31, thereby being assembled with at least one second flexible body 32. It is understandable that since there are multiple power sources 200 and multiple neutral gear actuators 70, there are also multiple second flexible bodies 32, and they correspond one-to-one with each power source 200. Specifically, there are two neutral gear mounting portions 312, which are assembled with one end of the two second flexible bodies 32, while the other ends of the two second flexible bodies 32 are respectively assembled with the two neutral gear actuators 70.

[0138] To facilitate the manipulation of the second toggle member 31 by the manipulation member 40, in this embodiment, the second toggle member 31 is provided with a second toggle portion 311, which is configured to engage with the manipulation member 40 and thereby be toggled by the manipulation member 40. Specifically, the second toggle portion 311 is a cylindrical structure with a notch, and one side of the manipulation portion 42 of the manipulation member 40 is also a cylindrical structure with a notch. Thus, the engagement of the two cylindrical structures enables the second toggle member 31 to be toggled by the manipulation member 40.

[0139] The specific operation mode of the operating member 40 can be combined with Figure 6-Figure 8 The operating member 40 is movably disposed on the carrier 10 to selectively activate the first toggle member 21 and the second toggle member 31 .

[0140] The shift device 100 is used to switch between the parking gear and the power gear when the operating member 40 shifts the first shift member 21; to maintain the power gear when the operating member 40 moves between the first shift member 21 and the second shift member 31; and to switch between the power gear and the neutral gear when the operating member 40 shifts the second shift member 31.

[0141] Combine Figure 6-Figure 8 At the same time, in order to facilitate the smooth engagement of the operating member 40 with the second toggle member 31 after it is separated from the first toggle member 21, it can also be understood that in order to facilitate the smooth engagement of the operating member 40 with the first toggle member 21 after it is separated from the second toggle member 31, in this embodiment, the shift device 100 further includes an auxiliary rod 50, the auxiliary rod 50 is relatively fixed to the carrier 10, the first toggle member 21 and the second toggle member 31 are respectively rotatably mounted on the two ends of the auxiliary rod 50, the operating member 40 is mounted on the auxiliary rod 50, and the operating member 40 is slidably disposed on the auxiliary rod 50 to selectively toggle the first toggle member 21 and the second toggle member 31. It can also be understood that the operating portion 42 of the operating member 40 is slidably mounted on the auxiliary rod 50, thereby selectively toggling the first toggle member 21 and the second toggle member 31.

[0142] Specifically, the two ends of the auxiliary rod 50 are connected to the parking box 12 and the neutral box 13, respectively. Furthermore, since the first toggle member 21 is disposed within the parking box 12 and the second toggle member 31 is disposed within the neutral box 13, the operating member 40 can be moved in conjunction with the plate 11 of the carrier 10 to switch positions between the parking box 12 and the neutral box 13. Furthermore, the auxiliary rod 50 can support the rotation of the first toggle member 21 and the second toggle member 31, while also providing a guide for the movement of the operating member 40.

[0143] As can be seen from the above description, the first toggle member 21 and the second toggle member 31 are spaced apart in the left-right direction, and the operating member 40 is located between them and, by moving in the left-right direction, selectively toggles the first toggle member 21 and the second toggle member 31. It can be understood that the left and right ends of the operating portion 42 of the operating member 40 are respectively configured to engage with the first toggle portion 211 of the first toggle member 21 and the second toggle portion 311 of the second toggle member 31, thereby selectively toggling the first toggle member 21 and the second toggle member 31.

[0144] Generally, there are many types of parking actuators 60, and there are many ways to implement them in the prior art, such as ratchet cable technology. In order to better implement parking of the power source 200, please refer to Figure 9 , Figure 9 The parking actuator 60 provided in this embodiment is shown to be adapted to the power source 200 .

[0145] Please refer to Figure 9 , and combined with Figure 3 and Figure 4 The parking actuator 60 is provided on the power source 200. When operated, the parking actuator 60 selectively unlocks and locks the power shaft 201 of the power source 200, thereby switching between the power gear and the parking gear. It can be understood that by unlocking and locking the power shaft 201, the power output of the power source 200 can be controlled.

[0146] In this embodiment, the power shaft 201 is the main shaft of the power motor 210 . Of course, it can also be other transmission shafts directly or indirectly connected to the main shaft of the power motor 210 .

[0147] Combine Figure 9 Specifically, the parking actuator 60 includes a parking mounting body 61, a parking body 62 and a parking fixing block 63. The parking mounting body 61 is used to be set on the power source 200, the parking body 62 is movably set on the parking mounting body 61, and the parking fixing block 63 is used to be connected to the power shaft 201; wherein, the parking body 62 is connected to the first flexible body 22, and the parking body 62 is used to disengage or engage with the parking fixing block 63, thereby unlocking or locking the power shaft 201. Figure 9At this time, the parking body 62 is engaged with the parking fixing block 63, and the vehicle is in a parking state.

[0148] In this embodiment, the parking fixing block 63 is fixed to the rear end of the power shaft 201, and the front end of the power shaft 201 cooperates with the transmission component 220. In this way, the parking actuator 60 will not interfere with the normal power output of the power motor 210.

[0149] In this embodiment, the parking body 62 is provided with a protrusion 621, and the parking fixing block 63 is provided with an embedding hole 631. The protrusion 621 is used to extend into the embedding hole 631 to achieve engagement, and to exit the embedding hole 631 to achieve disengagement. Figure 9 In the embodiment, the protrusion 621 is snapped into the embedding hole 631. Of course, in other embodiments, the parking body 62 can also be provided with the embedding hole 631, and the parking fixing block 63 can be provided with the protrusion 621. Alternatively, other engaging forms can be adopted.

[0150] To achieve a better engagement effect, in this embodiment, the number of embedding holes 631 is multiple, and the multiple embedding holes 631 are evenly distributed along the axial direction of the power shaft 201. At the same time, the number of protrusions 621 is also multiple, and the multiple protrusions 621 are evenly distributed along the axial direction of the power shaft 201. Generally, the number of protrusions 621 is less than or equal to the number of embedding holes 631.

[0151] Specifically, the number of the protrusions 621 is three, and the number of the embedding holes 631 is six.

[0152] With such an arrangement, the protrusion 621 can be better engaged when it is engaged with the embedding hole 631 . Even if it is not aligned, the protrusion 621 can be aligned with the embedding hole 631 after the vehicle slides a short distance.

[0153] In order to facilitate the resetting effect of the parking body 62, in this embodiment, the parking actuator 60 also includes a resetting member 64, which is arranged on the parking mounting body 61 and acts on the parking body 62. The parking body 62 is used to have a movement tendency to remain locked with the parking fixed block 63 under the action of the resetting member 64.

[0154] Specifically, in this embodiment, the parking mounting body 61 includes a parking mounting plate 611 and a plurality of parking guide columns 612, one end of the plurality of parking guide columns 612 is connected to the parking mounting plate 611, and the other end of the plurality of parking guide columns 612 is used to be set on the power source 200; wherein, the parking body 62 and the plurality of parking guide columns 612 are slidably mounted, the reset member 64 is mounted on the parking guide column 612, and one end of the reset member 64 is abutted against the parking mounting plate 611, and the other end of the reset member 64 is abutted against the parking body 62.

[0155] Specifically, the reset member 64 may be a spring. There are three parking guide posts 612 , which are evenly distributed around the axial direction of the power shaft 201 .

[0156] In other words, when the first flexible body 22 pulls the parking body 62 , the parking body 62 can be separated from the parking fixed block 63 . When the first flexible body 22 is released, the parking body 62 will quickly engage with the parking fixed block 63 under the action of the reset member 64 .

[0157] refer to Figure 9 Combined with Figure 7 In this embodiment, the parking control mechanism 20 further includes a first sleeve 24. One end of the first sleeve 24 is connected to the carrier 10 (specifically, the parking box 12), and the other end of the first sleeve 24 is connected to the parking mounting plate 611. The first flexible body 22 is movably disposed within the first sleeve 24. The first sleeve 24 effectively protects the first flexible body 22.

[0158] refer to Figure 9 , and combined with Figure 4 In this embodiment, the parking actuator 60 further includes a parking housing 65, which is disposed on the power source 200. The parking mounting body 61, the parking body 62, and the parking fixing block 63 are all disposed within the parking housing 65. Thus, the parking housing 65 can effectively protect these components.

[0159] Generally, there are many types of neutral actuators 70, and there are many ways to implement them in the prior art. In order to better implement the neutral operation of the power source 200, please refer to Figure 10 , Figure 10 The neutral actuator 70 provided in this embodiment is shown, and is adapted to the power source 200 .

[0160] Please refer to Figure 10 , and combined with Figure 3 and Figure 4 In this embodiment, the neutral actuator 70 is disposed at the neutral switch 230 of the power source 200. When operated, the neutral actuator 70 is configured to selectively trigger and deactivate the neutral switch 230, thereby achieving a shift between neutral and power gears. In other words, when the neutral actuator 70 triggers the neutral switch 230, the shift device 100 is in neutral; when the neutral actuator 70 deactivates the neutral switch 230, the shift device 100 is in power gear.

[0161] Specifically, the neutral actuator 70 includes a neutral mounting body 71 and a rocker 72. The neutral mounting body 71 is used to be set at the neutral switch 230, and the rocker 72 is movably set on the neutral mounting body 71; wherein, the rocker 72 is connected to the second flexible body 32, and the rocker 72 is used to move toward the neutral switch 230 to trigger the neutral switch 230, or to move away from the neutral switch 230 to reset the neutral switch 230 and thus release the trigger state.

[0162] It is understood that the neutral mounting body 71 is mounted to the housing of the power motor 210 of the power source 200, for example, by bolts. The neutral switch 230 has a self-reset function, that is, when the neutral switch 230 is pressed, the neutral switch 230 is displaced, and when the pressing is released, the neutral switch 230 automatically resets.

[0163] More specifically, in this embodiment, one end of the rocker 72 is hinged to the neutral mounting body 71, and the other end of the rocker 72 is connected to the second flexible body 32. The middle portion of the rocker 72 is used to trigger the neutral switch 230. To better trigger the neutral switch 230, a bump is provided in the middle portion of the rocker 72 toward the neutral switch 230 to better contact the neutral switch 230.

[0164] In order to facilitate the installation of the neutral switch 230 and to ensure that the rocker 72 can stably trigger it, in this embodiment, the neutral mounting body 71 is provided with a switch mounting hole 711, which is used for the neutral switch 230 to pass through. Specifically, the middle of the rocker 72 is aligned with the switch mounting hole 711.

[0165] Please refer to Figure 10 Combined with Figure 8 In this embodiment, the neutral operating mechanism 30 further includes a second sleeve 34. One end of the second sleeve 34 is connected to the carrier 10 (specifically, the neutral gear box 13), and the other end of the second sleeve 34 is connected to the neutral gear mounting body 71. The second flexible body 32 is movably disposed within the second sleeve 34. The second sleeve 34 can effectively protect the second flexible body 32.

[0166] According to a walking device 1 provided in this embodiment, the working principle of the walking device 1 is as follows:

[0167] Initial state: the shift device 100 is in the parking gear (P), that is, Figure 5In the auxiliary position 111, the first toggle member 21 releases the first flexible member 22. Under the action of the parking guide column 612 and the reset member 64, the parking body 62 connected to the first flexible member 22 moves rapidly toward the parking fixed block 63 and engages therewith. That is, the protrusion 621 on the parking body 62 is engaged with the embedding hole 631 of the parking fixed block 63, thereby locking the parking fixed block 63. At the same time, the power shaft 201 connected to the parking fixed block 63 is also locked, that is, the power motor 210 cannot output power. Because the handle 41 of the operating member 40 is limited by the shift groove 110 and the first toggle member 21 is affected by the first elastic retaining member 23, the shift device 100 can be maintained in the parking gear. At this time, the first toggle member 21 is in the parking position.

[0168] First switching state: The operator can pull the handle 41 to switch the handle 41 from the auxiliary position 111 to the first position 112. At this time, the operating portion 42 moves a certain position relative to the first toggle member 21, but still maintains the engagement with the first toggle member 21. At this time, the first toggle member 21 is in the parking position.

[0169] Second switching state: The operator can pull the handle 41, thereby switching the handle 41 from the first position 112 to the second position 113. At this point, the operating portion 42 rotates the first toggle 21, placing the first toggle 21 in the first power position. During this operation, the first toggle 21 pulls the first flexible body 22, causing the parking body 62 connected to the first flexible body 22 to disengage from the parking block 63 under the action of the parking guide post 612 (overcoming the elastic force of the reset member 64). Specifically, the protrusion 621 on the parking body 62 disengages from the recess 631 of the parking block 63. At this point, the power shaft 201 of the power motor 210 is unlocked, and the power motor 210 is energized to enable power output. Due to the action of the first elastic retaining member 23, the first toggle 21 remains in the first power position. In other words, the shift device 100 is in the power gear (D).

[0170] The third switching state: the operator can pull the handle 41 to switch the handle 41 from the second position 113 to the third position 114. At this time, the operating part 42 disengages from the first toggle member 21 and moves toward the second toggle member 31 and cooperates with the second toggle part 311 of the second toggle member 31. During this process, since the first toggle member 21 remains in the first power position, and the second toggle member 31 remains in the second power position under the action of the second elastic retaining member 33, that is, the shifting device 100 is in the power gear (D).

[0171] Fourth switching state: The operator can pull the handle 41, thereby switching the handle 41 from the third position 114 to the fourth position 115. At this time, the operating portion 42 rotates the second toggle member 31, and the second toggle member 31 switches from the second power position to the neutral position. During this operation, the second toggle member 31 pulls the second flexible body 32, causing the rocker 72 connected to the second flexible body 32 to rotate relative to the neutral mounting body 71. The rocker 72 contacts and drives the neutral switch 230 to move, triggering the neutral switch 230. After the neutral switch 230 is triggered, the power transmission between the power motor 210 and the transmission component 220 is released. In other words, the shift device 100 is in neutral (N).

[0172] The above can be understood as the shifting process of parking gear (P) → power gear (D) → neutral gear (N).

[0173] When shifting in reverse, that is, neutral (N) → power gear (D) → parking gear (P), it can be understood that:

[0174] The handle 41 is in the fourth position 115 , the second toggle member 31 is in the neutral position, and the first toggle member 21 maintains the first power position under the action of the first elastic retaining member 23 . At this time, the shift device 100 is in neutral (N).

[0175] The handle 41 switches to the third position 114, and the second toggle member 31 switches to the second power position after being toggled by the operating member 40. The first toggle member 21 maintains the first power position under the action of the first elastic retaining member 23. At this time, the shift device 100 is in the power gear (D).

[0176] The handle 41 switches to the second position 113, the second toggle member 31 maintains the second power position under the action of the second elastic retaining member 33, and the first toggle member 21 maintains the first power position under the action of the first elastic retaining member 23. At this time, the shift device 100 is in the power gear (D).

[0177] The handle 41 switches to the first position 112, the second toggle member 31 maintains the second power position under the action of the second elastic retaining member 33, the operating member 40 engages with the first toggle member 21, and the first toggle member 21 is switched to the parking position after being toggled by the operating member 40. At this time, the shift device 100 is in the parking gear (P).

[0178] The handle 41 switches to the auxiliary position 111, the second toggle member 31 maintains the second power position under the action of the second elastic retaining member 33, the operating member 40 is further engaged with the first toggle member 21, and the first toggle member 21 maintains the parking position. At this time, the shift device 100 is in the parking gear (P).

[0179] In combination with the above content, this embodiment designs a new shift device 100 to achieve new NPD gear integration, with a higher degree of integration, a simple and compact structure, an integrated design, and better cost.

[0180] In summary, the embodiment of the present invention provides a shifting device 100, a power steering system 1000, and a traveling device 1. The shifting device 100 includes a carrier 10, a parking control mechanism 20, a neutral control mechanism 30, and an operating member 40.

One end of the first flexible body 22 is connected to the first toggle member 21, and the other end of the first flexible body 22 is used to connect to the parking actuator 60. The first toggle member 21 is movably disposed on the carrier 10 and is used to operate the parking actuator 60 through the first flexible body 22 when it is toggled. The neutral control mechanism 30 includes a second toggle member 31 and a second flexible body 32. One end of the second flexible body 32 is connected to the second toggle member 31, and the other end of the second flexible body 32 is used to connect to the neutral actuator 70. The second toggle member 31 is movably disposed on the carrier 10 and is used to operate the neutral actuator 70 through the second flexible body 32 when it is toggled. The operating member 40 is movably arranged on the carrier 10 to selectively shift the first shift member 21 and the second shift member 31; the shift device 100 is used to switch between the parking gear and the power gear when the operating member 40 shifts the first shift member 21; is used to maintain the power gear when the operating member 40 moves between the first shift member 21 and the second shift member 31; and is used to switch between the power gear and the neutral gear when the operating member 40 shifts the second shift member 31.

[0181] By moving the operating member 40 on the carrier 10, the first toggle member 21 and the second toggle member 31 are selectively toggled, thereby operating the parking operating mechanism 20 and the neutral operating mechanism 30, so that the shift device 100 has a parking gear, a power gear and a neutral gear, and is convenient for switching between the parking gear, the power gear and the neutral gear, with a high degree of integration.
