Description

Technical Field

[0001] This invention relates to urban rail vehicle body structures, specifically a semi-integrated driver's cab structure that is highly versatile and applicable to most mask and console designs. Background Technology

[0002] Currently, interior components such as the driver's cab mask and control panel in urban rail transit are mostly connected to the cab frame using fasteners. Their external shape must match the cab frame structure; otherwise, interference or installation difficulties may occur. Consequently, the design of the cab frame directly impacts the space available for industrial design.

[0003] In previous urban rail vehicle driver's cab structures, the upper longitudinal beams of the driver's cab were connected to the roof. For example, Chinese invention patent CN 114435415B discloses a driver's cab structure and a rail vehicle. By using a detachable connection between the frame and the headgear, and without a frame at the front of the headgear, the problem of the frame structure being affected by the shape of the driver's cab is avoided, thus improving the versatility of the driver's cab frame. However, strictly speaking, this invention has limited effect on improving the versatility of the driver's cab frame. The shape of the side windows and the surrounding curved surfaces are still affected by the frame. Only the front of the headgear is frameless, which still has a significant impact on the external shape. Summary of the Invention

[0004] The purpose of this invention is to address the shortcomings of the prior art by providing a semi-integrated driver's cab and rail vehicle, which is mainly composed of side longitudinal beams, diagonal longitudinal beams, front crossbeams, columns, etc.

[0005] To solve the above technical problems, the present invention provides a semi-integrated driver's cab frame, characterized in that it includes: a front crossbeam, a left longitudinal beam and a right longitudinal beam, the two ends of the front crossbeam being fixed to the left longitudinal beam and the right longitudinal beam respectively through diagonal beams to form the middle frame of the semi-integrated driver's cab, and the middle frame of the semi-integrated driver's cab being fixed to the vehicle body chassis by welding several columns.

[0006] Furthermore, the rear ends of the left and right longitudinal beams are welded and fixed to the side wall columns of the vehicle body.

[0007] Furthermore, the inclined beam includes a first inclined longitudinal beam on the left, a second inclined longitudinal beam on the left, a first inclined longitudinal beam on the right, and a second inclined longitudinal beam on the right. The left end of the front crossbeam is connected to the left longitudinal beam in sequence through the first inclined longitudinal beam on the left and the second inclined longitudinal beam on the left. The right end of the front crossbeam is connected to the right longitudinal beam in sequence through the first inclined longitudinal beam on the right and the second inclined longitudinal beam on the right.

[0008] Furthermore, a reinforcing plate is provided at the junction of the central frame of the semi-integrated driver's cab and the column.

[0009] The semi-integrated driver's cab frame of this invention is assembled and welded from aluminum profiles and connected to the underframe via welding. It eliminates the need for a separate vehicle body frame, significantly reducing the impact of the frame on the cab's shape. This design, suitable for both monorail and passenger vehicles, features simple structure, minimal welding work, short production cycle, and low cost.

[0010] The present invention also claims a rail vehicle characterized in that it further includes the aforementioned half-body driver's cab frame.

[0011] Furthermore, this invention also claims protection for the manufacturing process of the semi-integrated driver's cab, characterized by including the following steps:

[0012] Step 1: After machining the aluminum profiles, they are positioned and welded using tooling to obtain the above-mentioned semi-body driver's cab frame;

[0013] Step 2: In the vehicle body assembly stage, the semi-body driver's cab frame is positioned using tooling, first welded and fixed to the vehicle body underframe, and then adjusted and welded to the side wall columns.

[0014] Step 3: During the final assembly stage, the driver's cab mask is placed on the vehicle body frame to meet the contour requirements. The two ends of the mask are welded and fixed to the side wall columns and the roof through brackets, and the one end is welded and fixed to the vehicle body underframe through brackets. The skirt panel is connected to the vehicle body underframe through brackets, and finally sealed with glue.

[0015] The face mask rests on the driver's cab frame but is not fixed to it. It is secured to the side walls, chassis, and roof via brackets. Its advantages include: 1. The driver's cab frame structure and face mask design do not interfere with each other, allowing for independent design based on requirements; 2. Simple installation and high on-site operability; 3. Fewer installation interfaces, fewer connecting brackets, less welding, and lower cost; 4. Large usable space inside the driver's cab, excellent visibility, and high driving comfort; 5. The semi-integrated driver's cab frame provides excellent interface and strength / rigidity support for equipment such as the control panel; 6. Simple driver's cab frame structure, minimal welding work, high manufacturability, and low cost. Attached Figure Description

Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] like Figure 1 As shown, the semi-submersible driver's cab frame in this embodiment includes a front crossbeam 5, a left longitudinal beam 1, a right longitudinal beam 8, a diagonal beam A, and a reinforcing plate B. The two ends of the front crossbeam 5 are fixed to the left longitudinal beam 1 and the right longitudinal beam 8 respectively via the diagonal beam A, forming the central frame of the semi-submersible driver's cab. The central frame of the semi-submersible driver's cab is welded and fixed to the vehicle body underframe 9 by five columns 4. The rear ends of the left longitudinal beam 1 and the right longitudinal beam 8 are welded and fixed to the vehicle body side wall columns 10. These five columns are arranged as follows: three columns are set below the front crossbeam 5, and one column is set on each side of the central frame of the semi-submersible driver's cab.

[0022] The inclined beam A includes a left first inclined longitudinal beam 3, a left second inclined longitudinal beam 2, a right first inclined longitudinal beam 6, and a right second inclined longitudinal beam 7. In this embodiment, the left end of the front crossbeam 5 is connected to the left longitudinal beam 1 in sequence through the left first inclined longitudinal beam 3 and the left second inclined longitudinal beam 2, and the right end of the front crossbeam 5 is connected to the right longitudinal beam 8 in sequence through the right first inclined longitudinal beam 6 and the right second inclined longitudinal beam 7.

[0023] like Figure 1 , Figure 2 In the embodiment shown, the front crossbeam 5 consists of two sections, which are welded to the left and right sides of the upper part of the column 4, respectively. The left side of the front crossbeam 5 and the left first diagonal longitudinal beam 3 are welded to the left and right sides of the upper part of the column 4, respectively. The left second diagonal longitudinal beam 2 and the left longitudinal beam 1 are welded to the left and right sides of the upper part of the column 4, respectively. The right side of the front crossbeam 5 and the right first diagonal longitudinal beam 6 are welded to the left and right sides of the upper part of the column 4, respectively. The right second diagonal longitudinal beam 7 and the right longitudinal beam 8 are welded to the left and right sides of the upper part of the column 4, respectively.

[0024] A reinforcing plate B is installed at the junction of the middle frame of the semi-submersible driver's cab and the column 4. Specifically, reinforcing plates are welded to the front crossbeam on both sides of the upper part of the middle column. Reinforcing plates are welded to the front crossbeam 5 and the first diagonal longitudinal beam 3 on both sides of the upper part of the left front column 4. Reinforcing plates are welded to the front crossbeam 5 and the first diagonal longitudinal beam 6 on both sides of the upper part of the right front column 4. Reinforcing plates are welded to the second diagonal longitudinal beam 2 and the left longitudinal beam 1 on both sides of the upper part of the rear left column. Reinforcing plates are welded to the second diagonal longitudinal beam 7 and the right longitudinal beam 8 on both sides of the upper right column.

[0025] The entire semi-framed driver's cab is constructed by welding aluminum profiles. The diagonal longitudinal beams, front crossbeams, columns, and reinforcing components are welded together to form the semi-framed driver's cab, which is then welded to the chassis. There is no upper frame; the face mask is directly mounted to the roof and side walls, significantly reducing the impact of the frame on the mask's shape. This design, suitable for monorail systems, features simple structure, minimal welding work, short production cycle, and low cost.

[0026] Based on the semi-body driver's cab frame of this embodiment, the manufacturing process of the semi-body driver's cab includes the following steps:

[0027] Step 1: After machining the aluminum profile, it is positioned and welded using tooling to obtain the half-body driver's cab frame of the present invention.

[0028] Step 2: In the vehicle body assembly stage, the half-body driver's cab frame is positioned using tooling, first welded and fixed to the vehicle body underframe 9, and then adjusted and welded to the side wall column 10.

[0029] Step 3: During the final assembly stage, the driver's cab mask is placed on the vehicle body frame to meet the contour requirements. The two ends of the mask are welded and fixed to the side wall column 10 and the roof through brackets, and the one end is welded and fixed to the vehicle body underframe 9 through brackets. The skirt panel is connected to the vehicle body underframe 9 through brackets, and finally sealed with glue.

[0030] Furthermore, the present invention also claims protection for a rail vehicle, including the half-body driver's cab frame of this embodiment.

[0031] In addition to the embodiments described above, the present invention may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by the present invention.
