Description

Waterproof ventilation passenger train hatch door

Technical Field

The utility model belongs to the technical field of the automobile parts technique and specifically relates to a waterproof ventilation passenger train hatch door.

Background

Waterproof and ventilation are two basic requirements of passenger car doors, but at present, passenger car doors mostly have the following two problems: firstly, in order to achieve the purposes of ventilation and heat dissipation, the existing cabin door is usually designed into a grid shape or a door plate is directly provided with air holes, although the ventilation capacity of the cabin door can be improved, the waterproof capacity of the cabin door is often poor, rainwater easily enters the cabin door, and potential safety hazards are caused to an internal high-voltage electric appliance; secondly, most of the existing passenger car doors with good waterproof performance adopt bent grid strips, and the gaps between every two adjacent grid strips are small, so that the inside and outside ventilation areas of the doors are small, and the ventilation capacity is poor.

Therefore, the passenger car cabin door with good waterproof performance and strong ventilation capacity is provided.

Disclosure of Invention

The utility model provides a waterproof ventilation passenger train hatch door, its main aim at solves above-mentioned problem.

The utility model adopts the following technical scheme:

a waterproof and ventilated passenger car cabin door comprises an inner frame, an outer skin and grid bars; the outer skin is fixedly arranged on the inner frame, and a plurality of vent holes are arranged in parallel; the plurality of grid strips are transversely arranged on the inner frame at intervals from top to bottom and are used for shielding the vent holes.

Furthermore, the plurality of grid bars are formed by bending a plane plate.

Furthermore, the cross section of the plurality of grid bars is approximately L-shaped.

Furthermore, the cross section of the plurality of grid bars is approximately Z-shaped.

Furthermore, a plurality of the vent holes are round vent holes.

Further, the lowest point of the vent hole located in the lowest row of the outer skin is flush with or slightly lower than the inner frame.

Furthermore, side plates for fixing the grid bars are arranged on two sides of the inner wall of the inner frame.

Furthermore, the bottom of the inner frame is provided with a water baffle.

Compared with the prior art, the utility model discloses the beneficial effect who produces lies in:

the utility model discloses an internal frame, outer covering and grid strip, outer covering are equipped with a plurality of bleeder vents, can form the ventilation passageway with the clearance between the two adjacent grid strips to improve the ventilation capacity of hatch door, and the grid strip can effectively support and keep out the rainwater and drench into the hatch door from the ventilation hole, make it taken away by the wind speed in the vehicle traveles, perhaps with rainwater water conservancy diversion to hatch door bottom, make it along the outside of ventilation hole discharge car of outer covering lower part, thereby improve the waterproof performance of hatch door. Therefore, the utility model overcomes prior art's is not enough, has compromise and optimized the ventilation and the waterproof performance of passenger train hatch door to have simple structure, firm reliable and whole pleasing to the eye advantage such as degree height.

Detailed Description

The following describes embodiments of the present invention with reference to the drawings. Numerous details are set forth in the following description in order to provide a thorough understanding of the present invention, but it will be apparent to one skilled in the art that the present invention may be practiced without these details.

Referring to fig. 1 and 2, a waterproof and ventilated passenger car door includes an inner frame 1, an outer skin 2, and a grille strip 3; the outer skin 2 is fixedly arranged on the inner frame 1 and is provided with a plurality of vent holes 21 in parallel; the plurality of grid bars 3 are transversely arranged on the inner frame 1 at intervals from top to bottom and used for shielding the vent holes 21. The hatch door of the utility model adopts the cavity type design of the outer skin 2 and the inner frame 1, and the clearance between two adjacent grid bars 3 and a plurality of ventilation holes 21 form a ventilation channel, thereby effectively ensuring the ventilation capability and timely ventilating and radiating the internal high-voltage electric appliance; the grid strips 3 are transversely arranged on the inner side of the vent hole 21 from top to bottom, so that rainwater is effectively prevented from being drenched into the cabin door from the vent hole 21, the rainwater is taken away by the wind speed in the running process of the vehicle, the grid strips 3 can also guide the rainwater to the bottom of the cabin door, the rainwater is discharged out of the vehicle along the vent hole 21 on the lower portion of the outer skin 2, and the waterproof performance of the cabin door is further improved.

Referring to fig. 2 and 3, the plurality of grid bars 3 are formed by bending a flat plate material, and have a substantially L-shaped or Z-shaped cross section, and in order to sufficiently ensure ventilation performance, the grid bars 3 having an L-shaped cross section are preferred in the present embodiment. Further, in order to ensure the waterproof performance, an overlap distance of a certain height may be provided in the vertical direction between the adjacent two grating strips 3.

Referring to fig. 2, 3 and 4, side plates 11 for fixing the grill 3 are provided at both sides of the inner wall of the inner frame 1, and a water guard 12 for preventing accumulated water from flowing into the vehicle is provided at the bottom of the inner frame 1. During production and manufacture, the inner frame 1 is formed by welding rectangular pipes, then is welded with the grid bars 3, the side plates 11 and the water baffles 12, is respectively sealed by gluing at the joints, and finally the outer skin 2 is welded or glued to the inner frame 1.

Referring to fig. 2 and 3, the lowest point of the vent hole 21 in the lowest row of the outer skin 2 is flush with or slightly lower than the inner frame 1, so that the accumulated water at the bottom of the cabin door can be smoothly discharged out of the vehicle. Preferably, the plurality of vent holes 21 are circular vent holes.

The above-mentioned be the utility model discloses a concrete implementation way, nevertheless the utility model discloses a design concept is not limited to this, and the ordinary use of this design is right the utility model discloses carry out immaterial change, all should belong to the act of infringement the protection scope of the utility model.
