Abstract
Description
Technical Field
[0001] This utility model relates to the field of louver manufacturing technology, and in particular to a louver blade. Background Technology
[0002] Venetian blinds are widely used in daily life and the transportation machinery industry. When opened, they primarily facilitate ventilation and heat exchange for the cooled components. Currently, the veneers installed in motor vehicles mostly have a single, curved blade structure. During heavy rain or high humidity, rainwater and moisture can easily penetrate the veneers, causing excessive internal humidity and affecting the lifespan of various vehicle components. Utility Model Content
[0003] The purpose of this utility model is to overcome the shortcomings of the prior art. This utility model provides a louver blade that can effectively prevent water vapor or rainwater from seeping in.
[0004] To address the aforementioned problems, this utility model proposes a louver blade, comprising a blade body, wherein the cross-section of the blade body is a multi-segment bent structure, the two sides of the blade body are bent in opposite parallel directions to form a first bent segment, and the two sides of the first bent segment are bent toward the blade body to form a second bent segment.
[0005] As an improvement to the above technical solution, the included angle between the first bending segment and the second bending segment is 110°-140°.
[0006] As an improvement to the above technical solution, the second bending sections on both sides of the blade body are parallel to each other.
[0007] As an improvement to the above technical solution, a first protruding section is provided at the bending convex corner on the front side of the blade body, and a second protruding section is provided at the bending convex corner on the back side of the blade body.
[0008] As an improvement to the above technical solution, two adjacent first protrusions are parallel to each other, and two adjacent second protrusions are parallel to each other.
[0009] As an improvement to the above technical solution, both the first protrusion and the second protrusion are inclined toward the bottom of the blade body.
[0010] As an improvement to the above technical solution, the angle between the first protruding segment and the horizontal plane is 10-20°, and the angle between the second protruding segment and the horizontal plane is 30-45°.
[0011] As an improvement to the above technical solution, the louver blades are integrally molded.
[0012] The following are the beneficial effects of implementing this utility model:
[0013] The louver blades of this invention have a multi-segment bent cross-section. Since there are multiple louver blades inside the louver, the gaps between two adjacent louver blades also form multi-segment bent spaces, which greatly reduces the possibility of rainwater splashing into the interior through the louver. In addition, the two sides of the blade body are bent in opposite parallel directions to form the first bent segment, and the sides of the two first bent segments are bent towards the blade body to form the second bent segment. The first and second bent segments act as a barrier, so that when water vapor enters the gaps between the louver blades, it is easy to condense into water droplets on the surface of the blades, and the water mist cannot penetrate into the interior of the louver. Attached Figure Description
[0014] Figure 1 This is a cross-sectional view of a louver blade according to an embodiment of the present invention. Detailed Implementation
[0015] 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.
[0016] See Figure 1 As shown, this utility model embodiment provides a louver blade, including a blade body 1. The cross-section of the blade body 1 is a multi-segment bent structure. The two sides of the blade body 1 are bent in opposite parallel directions to form a first bent segment 2. The two sides of the first bent segment 2 are bent toward the blade body 1 to form a second bent segment 3.
[0017] The louver blades of this invention have a multi-segment bent cross-section in the blade body 1. Since there are multiple louver blades inside the louver, the gaps between two adjacent louver blades also form multi-segment bent spaces, which greatly reduces the possibility of rainwater splashing into the interior through the louver. In addition, the two sides of the blade body 1 are bent in opposite parallel directions to form a first bent segment 2, and the sides of the two first bent segments 2 are bent toward the blade body 1 to form a second bent segment 3. The first bent segments 2 and the second bent segments 3 act as a barrier, so that when water vapor enters the gaps between the louver blades, it is easy to condense into water droplets on the surface of the blades, and the water mist cannot penetrate into the interior of the louver.
[0018] Preferably, the angle between the first bending segment 2 and the second bending segment 3 is 110°-140°. When the angle is less than 110°, the second bending segment 2 cannot effectively block water, increasing the amount of rainwater splashing onto the louver slats and increasing the risk of rainwater entering the louvers. When the angle is greater than 140°, the gap between two adjacent louver slats on the front of the louvers will be too small, preventing the louvers from dissipating heat to the outside in a timely manner.
[0019] More preferably, the second bending segments 3 on both sides of the blade body 1 are parallel to each other.
[0020] Preferably, a first protruding section 4 is provided at the bend angle on the front side of the blade body 1, and a second protruding section 5 is provided at the bend angle on the back side of the blade body 1. The first protruding section 4, the second protruding section 5, and the surface of the blade body 1 form a plurality of groove structures. These groove structures effectively block rainwater and also have a drainage function, which can drain rainwater that splashes into the gaps between the blades.
[0021] Preferably, two adjacent first protrusions 4 are parallel to each other, and two adjacent second protrusions 5 are parallel to each other. This parallel arrangement helps improve the drainage capacity and prevents rainwater from accumulating in the grooves.
[0022] Preferably, both the first protruding segment 4 and the second protruding segment 5 are inclined toward the bottom of the blade body 1. This inclination toward the bottom of the blade body 1 facilitates the drainage of rainwater to the bottom of the louver.
[0023] Ideally, the angle between the first protruding segment 4 and the horizontal plane is 10-20°, and the angle between the second protruding segment 5 and the horizontal plane is 30-45°.
[0024] Preferably, the louver blades are a one-piece molded structure. The louver blades are directly formed by extrusion, eliminating the bending step, greatly simplifying production and reducing costs.
[0025] 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.
