Description

TECHNICAL FIELD

[0001] The utility model belongs to the field of railway vehicles, and particularly relates to a wind deflector mounting structure suitable for metro vehicles. BACKGROUND

[0002] For the longitudinal seat of the urban rail, a wind deflector component is often arranged at both ends, which prevents the wind from blowing on the passengers when the door is opened, affects the riding comfort, and facilitates the passengers to hold when getting on and off the vehicle. In special cases, the passengers are prevented from falling. For most projects, the wind deflector component adopts a "base + wind deflector" structure.

[0003] However, in the design process, if the screw structure is adopted when the size of the base is large, the exposed screw will affect the artistic effect. If the snap fastener scheme is adopted, the snap fastener is prone to aging due to being non-metallic, and the disassembled component may be deformed if the force is large during the disassembly process, which affects the maintenance efficiency. Due to the above structural problems, the artistic modeling is limited, and the artistic effect of the whole vehicle is affected. CONTENT OF THE UTILITY MODEL

[0004] The utility model mainly aims at designing a wind deflector base structure which is convenient to disassemble, solves the problem that the size of the base of the wind deflector component is limited and affects the artistic effect, and can also solve the problem of work efficiency.

[0005] The utility model is realized by the following technical schemes:

[0006] A wind deflector mounting structure suitable for metro vehicles, comprising a frame 1 and a buckle cover 2, a buckle 2-1 is arranged on the buckle cover 2 in the area where the screw can be shielded, a socket 1-1 is arranged on the corresponding position of the frame 1, the buckle 2-1 is made of spring steel, one end is connected with the screw column of the buckle cover 2, the other end is provided with a slope surface with an inclination of 10°, the socket 1-1 adopts a bending structure, in the area where the screw cannot be shielded, a screw column is arranged on the frame 1, and a countersunk hole is arranged on the buckle cover 2 corresponding to the screw column, and when the frame 1 and the buckle cover 2 are connected through the plug-in structure, the frame 1 and the buckle cover 2 are connected through the plug-in structure.

[0007] The utility model adopts a mixed structure of "screw + plug-in", and has the following beneficial effects:

[0008] 1. Aesthetically pleasing: the structure of the utility model is connected through the plug-in structure, the screw is not exposed, the appearance of the wind deflector component is improved, the artistic modeling is diversified, and the appearance of the whole vehicle is improved.

[0009] 2. High work efficiency: in order to improve the appearance, the buckle structure is used for the wind deflector base with a large size in the prior art, in order to ensure the reliability of the structure, a buckle with a large clamping force is often used, which reduces the work efficiency during disassembly. The structure can be quickly inserted, and the work efficiency is improved.

[0010] 3. Cost saving: the buckle with larger clamping force is easy to deform during disassembly, and the cover needs to be replaced. The structure does not have this problem, and the material cost can be saved. BRIEF DESCRIPTION OF DRAWINGS

[0015] The utility model discloses a windshield component traditional single screw structure or buckle structure is changed to "screw + insertion" hybrid structure.

[0016] As shown in Figures 1-3 , the windshield base mainly includes frame 1, cover 2, and the main technical features are: for the area that the screw cannot shield, 3 buckles 2-1 are arranged on the cover 2, and the socket 1-1 is arranged on the corresponding position of the frame 1. The buckle 2-1 is made of spring steel, one end is connected with the screw thread column of the cover 2, the other end is provided with a slope surface with a slope of 10°, which facilitates the buckle 2-1 to be inserted into the gap between the socket 1-1 of the frame 1, the socket 1-1 adopts a bending structure, which reduces the distance between the buckle 1-1, thereby increasing the clamping force between the frame 1 and the cover 2. In the area that can shield the screw, the frame 1 is provided with a screw thread column, and the counterbore hole is arranged on the corresponding cover 2, when the frame 1 and the cover 2 are connected through the insertion structure, in order to prevent the cover 2 from falling off, the counterbore screw is used for connection.
