Description

Technical Field

[0001] This utility model belongs to the field of vehicle technology, and in particular relates to a vehicle steering system. Background Technology

[0002] like Figure 1 As shown, the existing model vehicle and real vehicle (full-size car) control systems can only switch sequentially between modes one to four. They cannot directly switch from steering mode one to steering mode three or steering mode four, nor can they directly switch from steering mode two to steering mode four. The reverse switching sequence is also not possible, which is inconvenient and affects the user experience.

[0003] For model vehicles and full-size cars, the steering system generally needs to switch between different modes in a predetermined sequence, and cannot jump to achieve real-time control, resulting in the vehicle being unable to steer flexibly. Utility Model Content

[0004] The purpose of this utility model is to provide a vehicle steering system that solves the technical problem that existing steering systems generally require switching between different modes in a predetermined sequence, making it impossible to jump between modes and achieve real-time control, thus preventing the vehicle from steering flexibly.

[0005] To achieve the above objectives, this utility model provides a real-time, fully proportional, all-wheel-drive-by-control vehicle steering system, comprising: a vehicle body, a control unit, and a receiving unit; the control unit is built into or externally mounted on the vehicle body, and the receiving unit is located on the vehicle body; the control unit is used to send front wheel steering signals and rear wheel steering signals to the receiving unit according to user instructions; it also includes: a front steering gear and a rear steering gear, the front steering gear being connected to the front wheels to control the steering angle of the front wheels, and the rear steering gear being connected to the rear wheels to control the steering angle of the rear wheels; when the receiving unit receives the front wheel steering signal and / or the rear wheel steering signal, the front wheel steering signal controls the steering angle of the front wheels through the front steering gear; the rear wheel steering signal controls the steering angle of the rear wheels through the rear steering gear.

[0006] Optionally, it also includes an operating handle, the control unit being located within the operating handle, the operating handle being provided with a first control key and a second control key, the user transmitting the front wheel steering signal to the control unit through the first control key, the user transmitting the rear wheel steering signal to the control unit through the second control key, the first control key and the second control key operating independently of each other.

[0007] Optionally, both the first control key and the second control key are knobs.

[0008] Optionally, the vehicle body is provided with a front wheel assembly and a rear wheel assembly. The front wheel assembly includes a front device mounted on the vehicle body and one or more front wheels respectively located at both ends of the front device. The rear wheel assembly includes a rear device mounted on the vehicle body and one or more rear wheels respectively located at both ends of the rear device. The front wheel assembly and the rear wheel assembly can be freely turned by means of a drive shaft connection or without a drive shaft connection. The front steering gear is mounted on the front wheel assembly, and the rear steering gear is mounted on the rear wheel assembly.

[0009] Optionally, both the front wheel assembly and the rear wheel assembly are provided in two sets. A drive shaft for transmitting power can be provided between two adjacent sets of the front wheel assembly and between two adjacent sets of the rear wheel assembly, or a drive shaft without power transmission can be provided.

[0010] Optionally, both the front wheel and the rear wheel include a wheel body and a support. The support is hinged to the front device or the rear device. The wheel body is mounted on the support.

[0011] Optionally, both the front steering gear and the rear steering gear are hinged to a connector, which is hinged to the support on one side.

[0012] Optionally, both the front and rear devices are equipped with a rotating shaft. If there is no power, the rotating shaft can be omitted. Alternatively, the function of forward and backward steering can be achieved with or without power. The rotating shaft is driven by meshing with the drive shaft through a bevel gear. The rotating shaft is hinged to the corresponding front wheel or rear wheel.

[0013] Optionally, the vehicle is a remote-controlled model car, and also includes a control handle, which is independent of the vehicle body. The control unit is located inside the control handle, and the control unit transmits the front wheel steering signal and the rear wheel steering signal to the receiving unit via wireless or wired transmission.

[0014] Optionally, both the front and rear wheels are steered in real-time with full proportional steering.

[0025] The embodiments of the present invention are described in detail below, examples of which 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 intended to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0026] In the description of the embodiments of this utility model, it should be understood that the terms "length", "width", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of embodiments of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0028] In this embodiment of the invention, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this embodiment of the invention according to the specific circumstances.

[0029] like Figures 2 to 4 As shown, this utility model embodiment provides a vehicle steering system, including a vehicle body 100, a control unit 200, a receiving unit 300, a front steering gear, and a rear steering gear 130.

[0030] The control unit 200 is built into or externally placed on the vehicle body 100, and the receiving unit 300 is located on the vehicle body 100. The control unit 200 is used to send the front wheel steering signal and the rear wheel steering signal to the receiving unit 300 according to the user's instructions. The front steering gear is connected to the front wheel 111 and is used to control the steering angle of the front wheel 111. The rear steering gear 130 is connected to the rear wheel 121 and is used to control the steering angle of the rear wheel 121. When the receiving unit 300 receives the front wheel steering signal and / or the rear wheel steering signal, the front wheel steering signal controls the steering angle of the front wheel 111 through the front steering gear, and the rear wheel steering signal controls the steering angle of the rear wheel 121 through the rear steering gear 130.

[0031] It is understandable that, in cases like Figure 1 The existing vehicle steering system shown only has four steering modes: front wheels 111 turn left and rear wheels 121 go straight; front wheels 111 go straight and rear wheels 121 turn right; front wheels 111 and rear wheels 121 turn left simultaneously; and front wheels 111 turn left and rear wheels 121 turn right. Users need to constantly control the vehicle to cycle through these four modes until the vehicle is in the desired mode, which is very inconvenient.

[0032] In the vehicle steering system provided in this embodiment of the present invention, the front wheels 111 and the rear wheels 121 can be steered separately and are independent of each other. That is, the front wheels 111 can achieve steering at any angle within a certain range, while the rear wheels 121 can also achieve steering at any angle within a certain range without being limited by the steering angle of the front wheels 111. The front wheels 111 and the rear wheels 121 are not limited by the existing vehicle steering system which requires switching between different modes in a predetermined sequence. This enables real-time control, flexible steering, and convenient operation.

[0033] Specifically, such as Figure 2 As shown, during use, the user can send steering instructions to the control unit 200 via a device that controls direction, such as buttons, a rotary dial, or an operation panel. Upon receiving the instruction, the control unit 200 encodes the analog signal using a microcontroller's encoding program and outputs it to the receiving unit 300. The receiving unit 300, upon receiving the encoded front wheel steering signal or rear wheel steering signal, decodes the signal and controls the steering angle of the front wheels 111 via the front steering mechanism, and controls the steering angle of the rear wheels 121 via the rear steering mechanism 130. It should be noted that the user can send only one of the front wheel steering instructions and the rear wheel steering instructions, or send both simultaneously.

[0034] In some embodiments of this invention, an operating handle (not shown in the figures) is also included. A control unit 200 is located within the operating handle, which is equipped with a first control key and a second control key. The user transmits a front wheel steering signal to the control unit 200 via the first control key, and transmits a rear wheel steering signal via the second control key. The first and second control keys operate independently of each other. Specifically, in some embodiments of this invention, both the first and second control keys can be knobs, rotary dials, operating panels, or levers. The user achieves real-time transmission of angle signals by rotating the first and second control keys at different angles.

[0035] like Figure 3 and Figure 4 As shown, in some embodiments of this utility model, a front wheel assembly 110 and a rear wheel assembly 120 are provided on the vehicle body 100. The front wheel assembly 110 includes a front device mounted on the vehicle body 100 and two front wheels 111 respectively disposed at both ends of the front device. The rear wheel assembly 120 includes a rear device 122 mounted on the vehicle body 100 and two rear wheels respectively disposed at both ends of the rear device 122. The front wheel assembly 110 and the rear wheel assembly 120 are connected by a drive shaft 140 (a drive shaft is not required if a drive is needed). A front steering gear is mounted on the front wheel assembly 110, and a rear steering gear 130 is mounted on the rear wheel assembly 120. Specifically, the steering mode can be used for front-wheel drive, rear-wheel drive, or all-wheel drive.

[0036] like Figure 3 As shown, in some embodiments of this utility model, both the front wheel assembly 110 and the rear wheel assembly 120 are provided with two sets. Of course, in other embodiments of this utility model, it is also possible to provide one or more sets for each of the front wheel assembly 110 and the rear wheel assembly 120. When both the front wheel assembly 110 and the rear wheel assembly 120 are provided with multiple sets, the corresponding front steering gear and rear steering gear 130 must also be provided with multiple sets. The more sets of steering gears added, the more front wheel assemblies 110 and rear wheel assemblies 120 need to be added accordingly.

[0037] In some embodiments of this utility model, both the front wheel assembly 110 and the rear wheel assembly 120 include a wheel body and a support 1211. The support 1211 of the front wheel assembly is hinged to the front device, and the support 1211 of the rear wheel assembly 120 is hinged to the rear device 122. Figure 4As shown, taking the rear wheel assembly 120 as an example, the support 1211 can rotate relative to the rear device 122 around a vertical axis. The wheel is mounted on the support 1211. A first connector 150 is provided between the two supports 1211 on the rear device 122. The two ends of the first connector 150 are hinged to the two supports 1211 respectively. When the rear steering gear 130 controls one of the supports 1211 to rotate, the two supports 1211 are driven by the first connector 150 and turn synchronously, thereby realizing the synchronous steering of the rear wheel 121. The steering structure and steering method of the front wheel assembly 110 are the same, and will not be described again here.

[0038] like Figure 4 As shown, in some embodiments of this utility model, both the front steering gear and the rear steering gear 130 are hingedly equipped with connectors 160, and the connectors 160 are hinged to the support 1211 on one side. Taking the rear wheel assembly 120 as an example, when the rear steering gear 130 rotates at a certain angle, it will drive the second connector 160 to rotate. The second connector 160 can push or pull the support 1211 to rotate, thereby realizing the steering of the rear wheel 121. The steering principle of the front steering gear is the same, and will not be described again here.

[0039] In some embodiments of this utility model, the vehicle may be a remote-controlled model car. The vehicle also includes an operating handle, which is independent of or inside the vehicle body 100. The control unit 200 is located inside the operating handle. The control unit 200 sends front wheel steering signals and rear wheel steering signals to the receiving unit 300 via wireless or wired transmission to realize remote control of the vehicle.

[0040] In some embodiments of this invention, both the front and rear wheels are steered in real-time with full proportional steering.

[0041] It should be noted that the vehicle system in this utility model is applicable to non-independent suspension vehicles with transmission, non-independent suspension vehicles without transmission, independent suspension vehicles without transmission, and independent suspension vehicles with transmission.

[0042] The above description, in conjunction with specific preferred embodiments, provides a further detailed explanation of this utility model. It should not be construed that the specific implementation of this utility model is limited to these descriptions. For those skilled in the art, the architectural form of this utility model can be flexibly varied without departing from its concept, and a series of products can be derived. Any simple deductions or substitutions should be considered as falling within the patent protection scope defined by the submitted claims.
