Description

Technical Field

[0001] This invention relates to the field of driver's cab technology, and more particularly to a driver's cab structure with a wide field of vision. Background Technology

[0002] The driver's cab, as the core control and driving space of a driving vehicle (such as automobiles, construction machinery, and special-purpose vehicles), is directly related to the driver's operational safety, visibility, and ease of use, and is a key element in ensuring efficient and safe driving. However, the existing cab structures of driving vehicles still have many shortcomings that need improvement in practical applications, as follows: 1. Significant blind spots and high safety risks: Using the driver's forehead as the center point of a clock with its hands placed parallel to the driver's face, and the direction the driver's eyes are looking directly at the front of the vehicle as the 12 o'clock position, the A-pillars (front pillars) of existing cabs are generally located in the driver's frontal or diagonally forward field of vision, especially the left A-pillar, which is often located in the left 10-11 o'clock position. When turning, changing lanes, or passing through intersections, this can easily obstruct the driver's observation of pedestrians, non-motorized vehicles, or obstacles in the left front, creating a significant blind spot. At the same time, the observation range of most cabs is fixed (usually only covering the area directly in front to 45° to the left and right), and cannot cover the entire forward field of vision from the 9 o'clock position to the 3 o'clock position clockwise. This makes it difficult for the driver to fully grasp the surrounding environment, increasing the probability of traffic accidents such as collisions and scrapes.

[0003] 2. Poor adaptability and low versatility of field of vision: Different models and uses of driving vehicles (such as small cars, medium-sized trucks, and construction machinery) have different requirements for the field of vision of the cab. However, the existing structure cannot flexibly adjust the starting and ending points of the field of vision according to the model of the driving vehicle. Manufacturers need to design the cab vision-related structure separately for different models, which not only increases the R&D cost and production cycle, but also reduces the versatility of parts.

[0004] 3. Difficulty in balancing safety and visibility: Some cabs optimize visibility by reducing the size of the A-pillar or lowering the strength of the A-pillar material in order to reduce blind spots. This results in the A-pillar failing to provide sufficient support and protection in the event of a collision or impact. At the same time, the existing safety canopy of the cab is mostly a simple frame structure with dispersed stress points and insufficient strength, which cannot form an effective safety space in the event of overturning or falling objects from a height. In addition, safety protection configurations (such as safety curtains) mostly only cover the front of the driver, lacking protection for the top of the head and the left front and right sides. In the event of a frontal impact, the interior of the door also lacks a targeted reinforcement structure, and the driver's multi-directional safety cannot be guaranteed.

[0005] 4. Insufficient ease of use: The opening method of the doors of high-roof vehicle (such as large trucks and special operation vehicles) is often limited by the cab space. When opened, they easily occupy the surrounding area, making it inconvenient for the driver and passengers to enter and exit. Some cab seats are fixed structures and cannot be adjusted according to the driver's size or entry and exit needs. Especially for larger drivers, the entry and exit process is easily blocked by the seat. Transparent windshield materials (such as windshields and side windows) are mostly fixed installations or can only be opened to a small extent. Flexible windshield materials lack suitable tracks and moving mechanisms, and the driver is easily blocked by the windshield material when entering and exiting. Moreover, the windshield structure cannot be flexibly adjusted according to the weather or usage scenario.

[0006] The deficiencies of the aforementioned existing technologies result in the cab failing to meet actual driving needs in terms of visibility, safety, adaptability, and convenience. There is an urgent need for a cab structure that can ensure a wide field of vision while also taking into account safety protection and ease of use. Summary of the Invention

[0007] In order to overcome the shortcomings of the prior art, one of the objectives of the present invention is to provide a cab structure with a wide field of vision.

[0008] One of the objectives of this invention is achieved through the following technical solution: A driver's cab structure with a wide field of vision is provided. The driver's cab structure is designed with the driver's forehead as the center point of a clock hand axis that is placed parallel to the driver's forehead. The direction in which the driver's eyes are looking directly in front of the vehicle is the 12 o'clock direction of the clock. The field of vision of the driver's cab extends clockwise from the 9 o'clock direction to the 3 o'clock direction on the driver's left, and there are no structures that obstruct or affect the field of vision within this field of vision.

[0009] A cab structure with an open field of vision that can be adjusted according to the model of the driving vehicle. The cab structure is based on the driver's brow as the center point of a clock placed parallel to the driver's head, with the driver's eyes looking directly in front of the driving vehicle at the 12 o'clock position of the clock. The starting point of the driver's field of vision is based on the 9 o'clock position to the driver's left and can be adjusted counterclockwise or clockwise. The ending point of the field of vision is based on the 3 o'clock position to the driver's right and can be adjusted counterclockwise or clockwise. After adjustment, there are no structures that obstruct or affect the field of vision.

[0010] Furthermore, the cab structure is designed with respect to the structural positions of the two A-pillars in front of the driver's vehicle. The left A-pillar is positioned counterclockwise from the driver's left 9 o'clock position, and the right A-pillar is positioned clockwise from the driver's right 3 o'clock position. The positions of the A-pillars do not obstruct the driver's line of sight from the left 9 o'clock position to the 3 o'clock position.

[0011] Furthermore, the cab structure is designed to accommodate the structural positions of the two A-pillars in front of the driver's vehicle; after the starting point of the field of vision is adjusted, the left A-pillar is positioned counterclockwise from that starting point; after the ending point of the field of vision is adjusted, the right A-pillar is positioned clockwise from that ending point; the positions of the A-pillars match the model of the driver's vehicle and ensure that there are no obstructing structures within the adjusted field of vision.

[0012] Furthermore, the A-pillar has a specific shape, and the A-pillar is connected to the stress point of the forward-extending high-strength safety protective roof structure at an appropriate position. The connection method includes straight line connection and arc line connection. The shape of the A-pillar can be adjusted according to the model of the cab. The adjusted A-pillar shape includes, but is not limited to, C-shaped, U-shaped, J-shaped, H-shaped, X-shaped, V-shaped, N-shaped, M-shaped, K-shaped, S-shaped, and L-shaped. The shape design of the A-pillar does not affect the observation line of sight as described in claim 1 or 2, and can resist external impacts to protect the driver's safety.

[0013] Furthermore, the cab structure also includes a safety canopy structure, which is based on the A-pillar structure of claims 3 or 4; the upper ends of the two A-pillars can be connected, or extend forward to above the driver's head, or extend forward beyond the driver's head to form a safety canopy; the two A-pillars are made of higher-specification, wider, thicker, stronger and denser materials; the upper ends of the two A-pillars can be connected, or extend forward to form stress points of the safety canopy structure, and the stress points are connected by high-strength materials to form a safety canopy structure, which together with the driver's vehicle constitutes a safety space.

[0014] Furthermore, the cab structure also includes a transparent windshield material and / or a frame; the transparent windshield material includes rigid transparent windshield material and flexible transparent windshield material, the flexible transparent windshield material being stretchable, bendable, and not affecting visibility; the flexible transparent windshield material can be combined with the cab door for linkage, or can be opened and closed independently; the left and right doors, the front of the cab, and suitable positions are provided with tracks or grooves matching the external dimensions of the movable flexible transparent windshield material, the tracks or grooves being used to facilitate the movement or stopping of the flexible transparent windshield material; when the driver and passengers enter and exit the cab, the flexible transparent windshield material can leave the front of the cab and enter a temporary space.

[0015] Furthermore, the cab structure also includes a structure that facilitates the opening and closing of the cab door without affecting the field of vision as described in claim 1 or 2; the door hinge of the cab door can be set vertically, obliquely, or horizontally; when entering or exiting the cab, the glass / frame or the door can be opened separately, or the glass / frame and the door can be opened simultaneously; the transparent windshield material / frame in front of the cab can be opened and closed by flipping forward, flipping backward, or by moving the entire roof upward, partially upward, moving the entire roof forward, or moving the left and right sides forward separately.

[0016] Furthermore, the cab structure also includes a movable safety seat; the movable safety seat includes a driver's seat, which is movable. When driving, the driver's seat is fixed at a position where the driver's forehead is located at the center point of the clock hand axis as described in claim 1. When entering or exiting the cab, the driver's seat is moved to a position that facilitates entry and exit. If the cab structure is provided with a passenger seat, the passenger seat can also be moved forward and backward to facilitate entry and exit from the cab.

[0017] Furthermore, the cab structure also includes a door adapted to a high-roof driving vehicle; the opening position of the door does not occupy the position of the cab structure described in claim 1 or 2, and the door can be opened at any position on the driving vehicle to facilitate the driver and passengers to enter and exit the cab, and the door is particularly suitable for high-roof driving vehicles in which people can walk upright inside the driving vehicle.

[0018] Furthermore, the cab structure also includes a safety protection structure; the safety protection structure includes a reinforced and weighted frame installed inside the door, the reinforced and weighted frame being located parallel to the upper part of the fender and transversely along the front-rear direction, the reinforced and weighted frame being used to resist frontal impact; the safety protection structure also includes a safety curtain airbag, the safety curtain airbag being equipped above the driver's head and in the left front and right directions of the cab.

[0019] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. Completely eliminate blind spots and improve driving safety: This invention sets the driver's cab's field of vision range to "extend clockwise from the driver's left 9 o'clock position to the 3 o'clock position," and by placing the A-pillars outside this field of vision (the left A-pillar is located counterclockwise from the 9 o'clock visible position, and the right A-pillar is located clockwise from the 3 o'clock visible position), it completely avoids the problem of traditional A-pillars obstructing the forward view, achieving a full-frontal view without blind spots, and effectively reducing traffic accidents caused by blind spots when turning or changing lanes; For different driving vehicles, the starting point (based on 9 o'clock) and ending point (based on 3 o'clock) of the field of vision can be flexibly adjusted. It can be adapted to multiple vehicle models without the need for a separate design of the vision structure, which significantly improves the structural versatility and reduces the manufacturer's R&D and production costs.

[0020] 2. Enhance multi-dimensional security protection, balancing visibility and strength: The A-pillar uses "higher specifications, wider dimensions, thicker thickness, higher strength and greater density materials", and can be connected to the stress points of the high-strength safety protection roof structure through straight or arc connection. At the same time, the shape of the A-pillar can be adjusted according to the cab model (such as C-type, U-type, S-type, etc.), which greatly improves the impact resistance of the A-pillar without affecting the field of vision. The safety canopy forms a stable load-bearing system based on the A-pillar structure (the top of the A-pillar is connected or extends to the top of the driver's head, and the load-bearing points are connected by high-strength materials), forming a closed safety space that can effectively protect the driver in the event of rollover, falling objects, or other accidents. In addition, the interior of the doors is equipped with a reinforced and weighted frame that is horizontally arranged in the front and rear directions. Together with the safety curtains on the driver's head, left front, and right sides, a multi-directional impact protection system is constructed to comprehensively improve the passive safety performance of the cab.

[0021] 3. Optimize ease of use and adapt to diverse needs: The movable safety seat design achieves "fixed while driving, movable when entering and exiting": when driving, the seat is fixed so that the driver's forehead is aligned with the reference point of the field of vision (the center point of the clock hand axis), ensuring the accuracy of the field of vision; when entering and exiting, the seat is moved to a convenient position, and the passenger seat can be adjusted forward and backward, which solves the problem of fixed seats obstructing the driver's entry and exit, and is suitable for drivers and passengers of different body types.

[0022] The vehicle door can be opened at any position without occupying the core space of the cab, allowing passengers to enter and exit upright. The transparent windshield material (including flexible and stretchable types) is equipped with an adaptable track and groove, which can be opened and closed independently or linked with the door. When the driver enters or exits, it can be moved to a temporary space to avoid obstruction. At the same time, the cab door hinge can be upright, diagonally or horizontally, and the windshield material / frame can be flipped (front and back) or moved (up and down / front and back), with flexible opening and closing methods to adapt to different usage scenarios such as rainy days and sunny days.

[0023] The above description is merely an overview of the technical solution of the present invention. In order to better understand the technical means of the present invention and to implement it in accordance with the contents of the specification, and to make the above and other objects, features and advantages of the present invention more apparent and understandable, preferred embodiments are described in detail below with reference to the accompanying drawings.
