Description

Technical Field

[0001] This utility model relates to the field of van manufacturing technology, and in particular to a louver. Background Art

[0002] Venetian blinds are widely used in daily life and the transportation machinery industry. When opened, venetian blinds are mainly used for ventilation and heat exchange of the cooled components. When closed, they mainly serve to provide some protection against rain, cold, and heat.

[0003] Existing locomotives are equipped with louvers for ventilation and heat exchange of cooling components, but their rainproofing effect is mostly poor. When a locomotive encounters heavy rain while traveling at high speed, rainwater violently impacts the louvers. At this time, the air pressure behind the louvers is lower than the outside air pressure, preventing rainwater from escaping and causing water seepage. For areas with strict rainproofing requirements, additional structures such as drip trays are often needed on the back of the louvers. Adding these structures inevitably reduces ventilation and heat dissipation area and increases weight and cost, making it less than ideal. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a louver that does not require the installation of a drip tray and can effectively solve the problem of easy water seepage during heavy rain.

[0005] To solve the above problems, this utility model proposes a louver, including a mounting frame and louver blades;

[0006] The mounting frame is provided with a plurality of louvers, and the bottom edge of the mounting frame is provided with a drainage groove, and the bottom of the drainage groove is provided with a drainage hole.

[0007] The two sides of the louver are bent in opposite directions to form a first bent edge; the edges of the two first bent edges are bent toward the louver at a predetermined angle to form a second bent edge.

[0008] As an improvement to the above technical solution, the louver includes a blade body, the two side edges of the blade body are bent in opposite directions at a predetermined angle to form a third bent edge, and the edges of the third bent edges on both sides are bent in parallel in opposite directions to form a first bent edge.

[0009] As an improvement to the above technical solution, a protruding section is provided at the junction of the blade body and the third bending edge.

[0010] As an improvement to the above technical solution, the angle between the protruding section and the third bending edge is 120-170°.

[0011] As an improvement to the above technical solution, a drainage transition cavity is provided inside the bottom frame, and the drainage hole passes through the drainage transition cavity.

[0022] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be described in further detail below with reference to the accompanying drawings.

[0023] See Figures 1 to 4 As shown, this embodiment of the utility model provides a louver, including a mounting frame 1 and louver blades 2.

[0024] This embodiment of the utility model improves the drainage performance of the louver by modifying the structure of the mounting frame 1 and the louver blades 2, and effectively simplifies its manufacturing cost.

[0025] Specifically, the mounting frame 1 is provided with a plurality of louvers 2, the bottom frame 11 of the mounting frame 1 is provided with a drainage groove 13, and the bottom of the drainage groove is provided with a drainage hole 12;

[0026] The two sides of the louver 2 are bent in opposite directions to form a first bent edge 21; the edges of the two first bent edges 21 are bent toward the louver 2 at a predetermined angle to form a second bent edge 22.

[0027] This utility model provides a louver with a drainage groove 13 inside the bottom frame 11 of the mounting frame 1, and a drainage hole 12 at the bottom of the drainage groove 13. When rainwater hits the louver 2, the first bent edge 21 formed by the parallel and opposite bends on both sides of the louver 2 acts as a water barrier and guides the accumulated water to the drainage groove. The drainage hole 12 of the drainage groove 13 is connected to the outside, and the accumulated water will be quickly discharged from the drainage hole 12. The second bent edge 22 formed by the edge of the first bent edge 21 bending towards the louver 2 at a predetermined angle acts as a water barrier and anti-fog, preventing rainwater from splashing into the interior and intercepting water mist to a certain extent. This utility model has a simple structure, can quickly drain accumulated water in heavy rain, and does not require the addition of a drip tray or other structures.

[0028] Preferably, the louver 2 includes a louver body 23, the two side edges of the louver body 23 are bent in opposite directions at a predetermined angle to form a third bent edge 24, and the edges of the two sides of the third bent edge 24 are bent in parallel in opposite directions to form a first bent edge 21. In this embodiment, the louver 2 has a multi-segment bent structure, which reduces the possibility of rainwater splashing into the back of the louver.

[0029] More preferably, a protruding section 25 is provided at the junction of the blade body 23 and the third bent edge 24. This protruding section, together with the blade body 23 and the third bent edge 24, forms a groove structure. When rainwater seeps into the louver through the gap, these groove structures can guide the rainwater to the bottom frame 11, and finally the accumulated water is discharged from the drain hole 12.

[0030] Preferably, the angle between the protruding section 25 and the third bent edge 24 is 120-170°. When the angle between the protruding section 25 and the third bent edge 24 is less than 120°, the angle of the groove structure is too small, which will cause water to accumulate in the groove and fail to provide effective drainage; when the angle between the protruding section 25 and the third bent edge 24 is greater than 170°, the angle of the groove structure is too large, which will cause the groove to fail to provide effective water blocking.

[0031] Preferably, the bottom frame 11 has a drainage transition cavity 15 inside, and the drainage hole 12 passes through the drainage transition cavity 15. The drainage transition cavity 15 provides an appropriate buffer space for drainage of the bottom frame, preventing water from overflowing from the drainage channel due to untimely drainage.

[0032] Preferably, shock-absorbing components 3 are provided at both ends of the louver 2. Since motor vehicles experience significant vibrations during operation, the louver 2 is prone to breakage and damage. Providing shock-absorbing components 3 at both ends of the louver 2 reduces the vibration amplitude and improves its service life.

[0033] Preferably, the shock absorber 3 is made of rubber or polyurethane.

[0034] Preferably, the mounting frame 1 has a mounting groove on its outer side, and a waterproof sheet 4 is provided on the inner wall of the mounting groove near the front of the mounting frame 1. The waterproof sheet 4 can effectively prevent rainwater from seeping in through the gap between the mounting frame 1 and the mounting baffle.

[0035] More preferably, decorative piece mounting grooves 14 are provided along the four sides of the back of the mounting frame 1, and decorative pieces 5 are provided in the decorative piece mounting grooves 14.

[0036] In addition, connecting brackets 6 are provided at the joints of the side frames of the mounting frame 1 to facilitate the connection and assembly of the mounting frame 1.

[0037] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications are also considered to be within the protection scope of this utility model.
