Description

A seat for a vehicle cab without an A-pillar and a vehicle equipped with the seat

Technical Field

The invention relates to the field of automated machinery, and in particular to a seat for an A-pillar-free vehicle cab and a vehicle equipped with the seat.

Background Art

Generally, there are three types of pillars in a car compartment, from front to back, they are A-pillar (front pillar), B-pillar (middle pillar), and C-pillar (rear pillar). The A-pillar is the connecting pillar between the windshield and the left front and right front doors, the B-pillar is located between the front door and the rear door, and the C-pillar is the connecting pillar between the left rear and right rear doors and the rear windshield. The common A-pillar of a car is a steel structure and is large in size. It will block the driver's view on the left and right sides in front of him, posing a safety hazard and easily leading to traffic accidents. Therefore, an A-pillar-free car has been developed, and the invention patent application with patent number: "202210825709" has been disclosed. "A small car without A-pillars and with a wide field of vision" has the characteristics of no A-pillars and a wide field of vision. In order to achieve a better field of vision, only a driving seat is installed in the cab of this type of small car, and no co-pilot seat is installed, which can achieve the best field of vision. At the same time, in order to save space and provide a better field of vision, pushing the cab forward is the best way to achieve it. After pushing the cab forward, it is not convenient to install doors on both sides, otherwise it is easy to conflict with the wheels. In this way, the exit and entry doors of the cab need to be opened on the rear side of the cab, but in this way it is not easy for the driver to leave the cab.

Example 2

As shown in Figure 4, an A-pillar-free automobile includes a chassis, a frame, a power system and a control system, wherein the power system is fixedly mounted on the chassis, a frame is fixedly mounted above the chassis, an interior compartment is formed between the frame and the chassis, and the interior compartment includes a cab and a passenger compartment, the frames on both sides of the passenger compartment are provided with openable and closable doors, a control system is fixedly mounted on the front chassis of the cab, rearview mirrors are fixedly mounted on the outer sides of the frames on both sides of the cab, an arc-shaped front windshield without an A-pillar is provided on the frame directly in front of the cab, the windshield extends to both sides of the cab, and the windshield extends at least to the rear side of the rearview mirror, and the extension distance cannot overlap with the passenger compartment at most, and the seat described in Example 1 is installed at the center of the cab.

The front windshield has a better driving field of vision due to the absence of an A-pillar, and the driving field of vision is made wider through the design of the curved windshield. In order to provide a wider field of vision, the windshield is designed to extend to both sides of the cab, so that doors cannot be designed on both sides of the cab. In this regard, the seat in Example 1 is added to provide multi-directional adjustment of the driving seat, so as to facilitate the driver to exit the cabin.

The front-opening door means that the door is hinged to the end of the frame near the rear, and the door opening and closing mouth is arranged at the end near the front of the vehicle. This design can facilitate the driver to open the door and go out, thus improving practicality.

There are no doors on both sides of the cab, and there is one and only one seat for driving in the cab, and the seat and the operating system are both located on the central axis of the cab in the driving state.

In order to provide a better driving vision, the seat and control system are placed on the central axis of the cab.

It should be noted that the car of the present invention is not necessarily a car without an A-pillar, but can also be a normal car. The front windshield of the cab is set to an arc shape, so that the cab protrudes forward, thereby making the A-pillar relatively moved backward, so that the A-pillar of the cab does not block the driver's line of sight, thereby improving the driver's field of vision, improving the driving field of vision, and preventing the A-pillar from blocking the driver's line of sight.

The purpose of the present invention is to prevent the front vision of the cab from having a blind spot due to the obstruction of the A-pillar, which may lead to misjudgment, and to improve the vision of the cab.

The above description is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiment. Any equivalent modifications or changes made by ordinary technicians in this field based on the contents disclosed by the present invention should be included in the protection scope recorded in the claims.
