Description

Technical Field

[0001] This utility model relates to the field of high-altitude operations technology, specifically to a steering angle display device for a high-altitude machine. Background Technology

[0002] Currently, aerial work platforms are not equipped with dedicated walking and steering angle display systems. During actual operation, operators typically have to lean out to observe the actual tire deflection to determine the current steering angle. This operation often takes place while the equipment is moving, which not only greatly distracts the operator but also poses significant safety hazards. Furthermore, relying on visual estimation to determine the steering angle is often limited by factors such as viewing angle and lighting, resulting in substantial errors and hindering precise control. To address these issues, this patent proposes an aerial work platform steering angle display device to improve operational safety and the accuracy of steering control. Utility Model Content

[0003] To solve the above technical problems, this utility model provides a steering angle display device for a high-speed machine, which installs a steering sensor on the pin of the steering wheel to facilitate the acquisition of the current steering angle and displays it on the platform operating handle.

[0004] The present invention adopts the following technical solution: A steering angle display device for a high-speed aircraft, comprising: Steering wheel pin, mounted on the steering wheel, has a mounting groove and anti-detachment grooves located on both sides of the mounting groove; A steering sensor has a mounting part at one end, a mounting post rotatably mounted on the mounting part, and retaining springs on both sides of the mounting post. The mounting post is inserted into a mounting groove, and the retaining springs are located in the anti-disengagement groove. The chassis controller is electrically connected to the other end of the steering sensor; The platform control handle is electrically connected to the chassis controller; The steering sensor, through the cooperation of the mounting post, snap ring, and steering wheel pin, achieves synchronous rotation with the steering wheel, ensuring the accuracy of the angle acquisition source. The chassis controller, as the information processing center, receives sensor signals and converts them into data that can be understood by the operating interface. The platform operating handle, as the information display terminal, transforms abstract electronic signals into intuitive angle information for the operator, allowing them to clearly grasp the tire steering status from the driving position without having to look around. This fundamentally eliminates the safety risks caused by visual estimation and significantly improves control precision.

[0005] Preferably, the mounting part is provided with mounting ears on its side, and the steering wheel pin is provided with connecting holes at corresponding positions. Bolts pass through the mounting ears and are connected to the connecting holes. The rigid fixing method of bolt connection provides double protection for the sensor, which greatly enhances the stability and reliability of the entire sensing component under vehicle vibration and complex working conditions. This prevents the sensor from loosening or shifting due to long-term use or bumps, and ensures the long-term accuracy of angle measurement.

[0006] Preferably, the anti-detachment groove includes a receiving portion and a first limiting portion and a second limiting portion located at the upper and lower ends of the receiving portion, providing a precise and structured space for the installation and limiting of the retaining ring; the receiving portion is used to support the retaining ring, while the upper and lower limiting portions work together to effectively limit the axial movement of the mounting post, prevent it from coming out of the mounting groove during vibration, and ensure the firmness of the mechanical connection.

[0007] Preferably, both the first limiting part and the second limiting part are slope structures, and the angle between the first limiting part and the horizontal plane is smaller than the angle between the second limiting part and the horizontal plane. By using the asymmetrical slope design, the guiding function of the snap ring installation is realized. The first limiting part with a smaller angle forms a blocking surface, making it more difficult for the snap ring to come out when it is disassembled or subjected to an upward impact.

[0008] Preferably, the retaining spring includes a protrusion and a first elastic portion and a second elastic portion located at the upper and lower ends of the protrusion. When the mounting post is located in the mounting groove, the first elastic portion is squeezed and deformed by the first limiting portion, thereby fitting with the first elastic portion. When the mounting post is inserted into the mounting groove, the elastic portion of the retaining spring deforms under the compression of the limiting portion, continuously generating a rebound preload. The preload ensures that the protrusion can always fit tightly in the anti-dislodgement receiving portion, effectively eliminating the assembly gap between components.

[0009] Preferably, the steering sensor is mounted on the steering wheel pin, and the mounting post rotates with the rotation of the steering wheel pin. By directly mounting the steering sensor on the steering wheel pin and having its mounting post rotate synchronously with the pin, the actual angle of the steering wheel can be directly measured, avoiding the transmission errors and lags that may be caused by measuring through intermediate connecting rods or other indirect methods, thus ensuring the immediacy and authenticity of the data display from the source.

[0010] Compared with the prior art, the present invention has the following advantages: 1. Fundamentally eliminate safety hazards: By displaying the steering angle in real time on the handle terminal, the operator no longer needs to look up or leave the operating position to visually inspect the tires during operation. This allows the operator to keep their attention on the working environment and path at all times, fundamentally avoiding potential accidents caused by distraction and unstable posture.

[0011] 2. Achieve high-precision steering control: By using sensors to directly measure angles, the previously vague angle judgments that relied on manual visual estimation are transformed into precise digital information displays. This significantly improves control accuracy, enabling the equipment to perform more precise steering and movement, especially in narrow or complex spaces.

[0012] 3. Reliable mechanical connection: The steering sensor and the steering wheel pin are connected by the "mounting column-mounting groove" and "circlip-anti-disengagement groove" and are further secured by bolts, forming a robust and stable mechanical structure that can effectively resist the continuous vibration generated by the aerial work platform during driving and operation, ensuring long-term durability.

Detailed Implementation

[0020] To facilitate understanding of the technical solution of this utility model, the following detailed description is provided in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1 like Figure 1-6 As shown, a steering angle display device for a high-speed aircraft includes: Steering wheel pin 1, which is set on the steering wheel, has a mounting groove 1-1 and anti-detachment grooves 1-2 located on both sides of the mounting groove 1-1; Steering sensor 2 has a mounting part 2-1 at one end. A mounting post 2-2 is rotatably mounted on the mounting part 2-1. Snap rings 2-3 are provided on both sides of the mounting post 2-2. The mounting post 2-2 is inserted into the mounting groove 1-1, and the snap rings 2-3 are located in the anti-disengagement groove 1-2. Chassis controller 3 is electrically connected to the other end of steering sensor 2; Platform operating handle 4 is electrically connected to chassis controller 3; The steering sensor achieves synchronous rotation with the steering wheel through the cooperation of the mounting post, snap ring, and steering wheel pin, ensuring the accuracy of the angle acquisition source.

[0022] The chassis controller 3 and platform operating handle 4 are both existing technologies and will not be described in detail. The chassis controller, as the information processing center, receives sensor signals and converts them into data that can be understood by the operating interface. The platform operating handle, as the information display terminal, transforms abstract electronic signals into intuitive angle information presented to the operator, allowing them to clearly grasp the tire steering status from the driving position without having to look around. This fundamentally eliminates the safety risks associated with visual inspection and significantly improves control accuracy.

[0023] In addition, the steering sensor 2 can be a steering sensor with model number APS028M.A3 manufactured by Shanghai Dingsheng Intelligent Technology Co., Ltd.

[0024] The mounting part 2-1 has a mounting ear 2-4 on its side, and a connecting hole 1-3 is provided at the corresponding position on the steering wheel pin 1. The bolt passes through the mounting ear 2-4 and is connected to the connecting hole 1-3. The rigid fixing method of bolt connection provides double protection for the sensor, which greatly enhances the stability and reliability of the entire sensing component under vehicle vibration and complex working conditions. This prevents the sensor from loosening or shifting due to long-term use or bumps, and ensures the long-term accuracy of angle measurement.

[0025] The anti-detachment groove 1-2 includes a receiving part 1-2-1 and a first limiting part 1-2-2 and a second limiting part 1-2-3 located at the upper and lower ends of the receiving part 1-2-1, providing a precise and structured space for the installation and limiting of the snap ring; the receiving part is used to support the snap ring, while the upper and lower limiting parts work together to effectively limit the axial movement of the mounting post (along with the sensor), preventing it from coming out of the mounting groove during vibration, and ensuring the firmness of the mechanical connection.

[0026] Both the first limiting part 1-2-2 and the second limiting part 1-2-3 are sloping structures, and the angle between the first limiting part 1-2-2 and the horizontal plane is smaller than the angle between the second limiting part 1-2-3 and the horizontal plane. By utilizing the asymmetrical sloping design, the guiding function of the snap ring installation is realized. The first limiting part 1-2-2 with a smaller angle forms a blocking surface, making it more difficult for the snap ring to come out when it is disassembled or subjected to an upward impact.

[0027] The retaining ring 2-3 includes a protrusion 2-2-1 and a first elastic part 2-2-2 and a second elastic part 2-2-3 located at the upper and lower ends of the protrusion 2-2-1. When the mounting post 2-2 is located in the mounting groove 1-1, the first elastic part 2-2-2 is squeezed and deformed by the first limiting part 1-2-2, thereby fitting with the first elastic part 2-2-2. When the mounting post is inserted into the mounting groove, the elastic part of the retaining ring deforms under the compression of the limiting part, continuously generating a rebound preload. The preload ensures that the protrusion can always fit tightly in the anti-disengagement groove receiving part, effectively eliminating the assembly gap between the parts.

[0028] The steering sensor 2 is mounted on the steering wheel pin 1, and the mounting post 2-2 rotates with the rotation of the steering wheel pin 1. By directly mounting the steering sensor on the steering wheel pin and making its mounting post rotate synchronously with the pin, the actual angle of the steering wheel can be directly measured, avoiding the transmission error and lag that may be caused by measuring through intermediate connecting rods or other indirect methods, thus ensuring the immediacy and authenticity of the data display from the source.

[0029] The above are merely preferred embodiments of this utility model. The scope of protection of this utility model is defined by the scope of the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of this utility model should also be considered as protection within the scope of this utility model.
