Description

Technical Field

[0001] This utility model relates to a wire-controlled chassis platform, and more particularly to a multi-angle adjustable wire-controlled chassis platform. Background Technology

[0002] Driven by the development of in-vehicle networks and microprocessors, vehicle control is moving towards integration and intelligence. Drive-by-wire chassis integrated control has become a key trend for realizing autonomous driving. It replaces traditional mechanical or hydraulic drives with electrical signal control, which has the advantages of simplifying structure, reducing weight, and reducing energy consumption.

[0003] Patent CN216969564U discloses an unmanned driving drive-by-wire chassis, including a chassis with an electrical box on top. This patent proposes controlling the rotation of a motor, which in turn drives a rotating shaft. This shaft rotation causes gears to rotate, and the gears mesh with a rack to control the steering of the tires. However, this patent still has some problems in practical use. Because the steering control in the aforementioned patent only applies to the front wheels, the maneuverability of the unmanned vehicle is severely limited when making U-turns in narrow sections or performing complex steering maneuvers requiring extremely small turning radii. This can easily lead to the vehicle getting stuck or failing to complete the steering along the intended path, making it difficult to meet the flexible passage requirements of unmanned driving in all scenarios.

[0004] Therefore, there is a need to provide a drive-by-wire chassis platform that can be adjusted at multiple angles. Utility Model Content

[0005] In order to overcome the shortcomings of existing patents where steering control only acts on the front wheels, which severely limits the maneuverability of unmanned vehicles when making U-turns in narrow sections or complex steering operations requiring a very small turning radius, and makes it easy for them to "get stuck" or fail to complete the steering according to the expected path, thus failing to meet the needs of flexible passage in all scenarios for unmanned driving, this utility model provides a drive-by-wire chassis platform that can be adjusted at multiple angles.

[0006] A multi-angle adjustable wire-controlled chassis platform includes a base plate, a rotating shaft, a mounting shell, a connecting plate, a connecting seat, suspension components, and wheels. Mounting shells are mounted on both sides of the base plate. A rotating shaft is rotatably mounted on each mounting shell, penetrating the base plate. A connecting plate is fixedly connected to the bottom of the rotating shaft. A connecting seat is fixedly connected to the end of the connecting plate away from the rotating shaft. Suspension components are mounted on both sides of the connecting seat. Wheels are mounted on the sides of the two suspension components that are far apart from each other. The platform includes a driven gear, a servo motor, a drive gear, and a controller. A driven gear is fixedly connected to the rotating shaft. A servo motor is mounted on the mounting shell, with its output shaft penetrating the mounting shell. A drive gear is fixedly connected to the output shaft of the servo motor, and a driven gear is fixedly connected to the rotating shaft. The drive gear meshes with the driven gear. A controller is mounted on the bottom of the base plate, and the controller's signal output terminal is electrically connected to the servo motor's signal input terminal.

[0007] To further explain, it also includes a pointer and a dial. The pointer is fixedly connected to the top of the rotating shaft, and the dial is installed on the top of the mounting housing. The rotating shaft passes through the dial.

[0008] To further explain, it also includes mounting plates, buffer dampers, and buffer plates. Mounting plates are installed on both sides of the base plate, and two buffer dampers are installed on the side of the two mounting plates that are far apart from each other. A buffer plate is installed between the two buffer dampers located on the same side of the base plate.

[0009] To further explain, it also includes a protective cover; a protective cover is installed at the bottom of the base plate, and the protective cover covers the controller.

[0010] To further explain, multiple heat dissipation grooves are provided on both sides of the protective cover.

[0011] To further explain, it also includes anti-slip blocks, with multiple sets of anti-slip blocks installed on the wheels.

[0012] This utility model has the following advantages: 1. The controller drives the servo motors on both sides to operate synchronously. The drive gear meshes with the driven gear to drive the rotating shaft to rotate, which in turn drives the entire base plate to rotate. This is then linked to the suspension assembly and wheels via the connecting plate and connecting seat for synchronous deflection. This achieves coordinated control of the steering angles of the front and rear wheels, significantly reducing the turning radius and enabling the unmanned vehicle to efficiently complete operations such as quick U-turns and right-angle turns in narrow road sections, greatly improving its spatial mobility and flexibility.

[0013] 2. When the unmanned vehicle is subjected to front and rear impact forces, the impact force first acts on the buffer plate, and then the buffer damper absorbs and dissipates the impact energy, thereby significantly reducing the impact force transmitted to the bottom plate and the upper body of the vehicle and improving driving stability.

[0019] First, it should be noted that in different described embodiments, the same components are given the same reference numerals or the same component names. The disclosure contained throughout this specification can be applied semantically to the same components having the same reference numerals or the same component names. The location descriptions selected in the specification, such as upper, lower, lateral, etc., also refer to the directly described and illustrated figures and are semantically applied to the new location when the location changes.

[0020] Example 1: A multi-angle adjustable wire-controlled chassis platform, see [reference] Figures 1-4 As shown, the system includes a base plate 1, a rotating shaft 2, a mounting shell 201, a connecting plate 3, a connecting seat 4, suspension components 5, and wheels 6. Mounting shells 201 are mounted on both sides of the base plate 1. A rotating shaft 2 is rotatably mounted on each mounting shell 201, penetrating the base plate 1. A connecting plate 3 is fixedly connected to the bottom of the rotating shaft 2. A connecting seat 4 is fixedly connected to the bottom of the connecting plate 3 by welding. Suspension components 5 are mounted on both sides of the connecting seat 4. Wheels 6 are mounted on the sides of the two suspension components 5 that are furthest apart from each other. Three sets of anti-slip blocks 18 are provided on each wheel 6. The anti-slip blocks 18 can improve the grip of the wheels 6, making the unmanned vehicle move more smoothly. It includes a driven gear 7, a servo motor 8, a drive gear 9, and a controller 10. The driven gear 7 is fixedly connected to the rotating shaft 2. The servo motor 8 is installed on the mounting housing 201 by bolt connection. The output shaft of the servo motor 8 passes through the mounting housing 201. The drive gear 9 is fixedly connected to the output shaft of the servo motor 8 by key connection. The driven gear 7 is fixedly connected to the rotating shaft 2 by key connection. The drive gear 9 meshes with the driven gear 7. The controller 10 is installed on the bottom of the base plate 1 by bolt connection. The signal output terminal of the controller 10 is electrically connected to the signal input terminal of the servo motor 8.

[0021] When the unmanned vehicle needs to be steered, the controller 10 controls the two servo motors 8 to start. The output shafts of the servo motors 8 rotate, driving the drive gear 9 to rotate. The drive gear 9 meshes with the driven gear 7, causing the rotating shaft 2 to drive the connecting plate and the connecting seat 4 to rotate. The connecting seat 4 drives the suspension components 5 on both sides and the wheels 6 on them to rotate synchronously. Thus, the controller 10 controls the rotation angle of the output shafts of the two servo motors 8, and precisely adjusts the rotation angle of the front and rear wheels 6 when the unmanned vehicle turns. This enables the unmanned vehicle to efficiently complete high-maneuverability operations such as quick U-turns and right-angle turns on narrow roads, improving the flexibility of the unmanned vehicle.

[0022] Example 2: Based on Example 1, refer to Figure 2 and Figure 3 As shown, it also includes a pointer 13 and a dial 14. The pointer 13 is fixedly connected to the top of the rotating shaft 2 by welding. The dial 14 is installed on the top of the mounting housing 201 by bolt connection. The rotating shaft 2 passes through the dial 14.

[0023] When the rotating shaft 2 rotates, it drives the pointer 13 to rotate as well. By observing the position of the pointer 13 on the dial 14, the current rotation angle of the base plate 1 can be read intuitively, which facilitates precise control of the steering angle of the front and rear wheels.

[0024] See Figure 1 and Figure 2 As shown, it also includes a mounting plate 15, a buffer damper 16, and a buffer plate 17. Mounting plates 15 are installed on both sides of the base plate 1. Two buffer dampers 16 are installed on the side of the two mounting plates 15 that are far apart from each other by bolts. A buffer plate 17 is installed between the two buffer dampers 16 located on the same side of the base plate 1 by bolts. The buffer plate 17 is arc-shaped. When the impact force is applied to the buffer plate, the arc-shaped structure can distribute the impact load more evenly and avoid stress concentration that could lead to local deformation or breakage.

[0025] When the unmanned vehicle is subjected to front and rear impact forces, the impact force first acts on the buffer plate 17. The buffer plate 17 transmits the impact force to the two buffer dampers 16 connected to it. The buffer dampers 16 absorb and dissipate the impact energy, thereby significantly reducing the impact force transmitted to the bottom plate 1 and the vehicle body above, and improving driving stability.

[0026] See Figure 2 As shown, it also includes a protective cover 11. The protective cover 11 is installed on the bottom of the base plate 1 by means of bolt connection. The protective cover 11 covers the controller 10. Four heat dissipation slots 12 are opened on both sides of the protective cover 11.

[0027] When the unmanned vehicle passes through waterways or rough roads, the protective cover 11 completely covers the controller 10, effectively isolating it from water splashes, dust, debris and physical collisions, thus protecting the controller 10. The heat dissipation slot 12 allows the heat generated by the controller 10 to be dissipated in time, preventing the controller 10 from overheating and causing performance degradation or damage.

[0028] The above-described embodiments are merely preferred embodiments of the present invention, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make various modifications, improvements, and substitutions without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the appended claims.
