Description

Technical Field

[0001] The utility model belongs to the technical field of automobile parts and relates to a sunshade curtain for a vehicle. Background Art

[0002] Sunshades are widely used in existing vehicles, which generally include curtain frames, curtains and rollers. As existing vehicles become larger and larger, the doors are also widened. As the doors are widened, the sunshades inside the doors also need to be widened. This results in the need to lengthen the width of the roller tube of the sunshade. The diameter of the roller tube of the sunshade is small, and its deflection increases with the increase of width. Because the two ends of the roller tube are connected to the two sides of the curtain frame, that is, there are support points at both ends of the roller tube, which causes the middle position of the roller tube to vibrate easily. Especially when the vehicle is bumpy or the door is closed, the middle position of the roller tube is prone to make abnormal noises due to vibration. Therefore, there is room for improvement. Utility Model Content

[0003] The utility model aims to solve the above problems in the prior art and proposes a sunshade for a vehicle.

[0004] The purpose of the utility model can be achieved through the following technical solutions: A vehicle sunshade, comprising: a roller tube, the roller tube is provided with a counterweight, the counterweight is close to the end of the roller tube so that the center of gravity of the roller tube deviates from its middle position and is close to the end of the roller tube.

[0005] Preferably, the counterweight is a tubular structure, and the counterweight is installed inside the winding tube.

[0006] Preferably, the interior of the coiled tube is filled with sound-absorbing sponge.

[0007] Preferably, it further comprises a curtain frame, wherein the roller tube is installed in the curtain frame.

[0010] Compared with the prior art, the beneficial effects of the utility model are:

[0011] 1. A counterweight is added inside the reel. The counterweight changes the center of gravity of the reel so that the center of gravity of the reel is located at the position of the counterweight. When the vehicle bumps or the door is closed, the vibration of the reel is concentrated at the center of gravity, and the center of gravity of the reel is away from its middle position and close to the shaft joint of the reel, so the vibration and abnormal noise generated by the reel can be reduced.

[0012] 2. The center of gravity adjustment is realized in a concealed manner, and the internal space is fully utilized to avoid the impact on the appearance and installation space. In addition, the tubular counterweight, as an internal structural component, can enhance the overall rigidity of the reel and improve the structural strength of the reel to a certain extent. In addition, the counterweight is designed to be tubular, which is convenient for direct embedding during the manufacturing or assembly process of the reel, without the need for complicated later addition steps, simplifying the production process and reducing the difficulty and cost of assembly.

[0018] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0019] like Figure 1-3 As shown, a vehicle sunshade includes: a roller tube 100, wherein the roller tube 100 is provided with a counterweight 200, and the counterweight 200 is close to the end of the roller tube 100 so that the center of gravity of the roller tube 100 deviates from its middle position and is close to the end of the roller tube 100.

[0020] By placing the counterweight 200 near the end of the roller tube 100, the center of gravity of the roller tube 100 is redistributed. Originally, due to the small diameter and long length of the roller tube 100, the center of gravity of the roller tube 100 is located in the middle. Especially during the driving of the vehicle or the vibration caused by the closing of the door, it is easy to cause the middle part of the roller tube 100 to deform due to lack of sufficient support, thereby causing abnormal noise. After adding the counterweight 200, the center of gravity of the roller tube 100 is no longer located in the middle position that is susceptible to vibration, but is guided to the vicinity of the more stable end, that is, closer to the connection point between the roller tube 100 and the side cover 310 of the curtain frame 300. This design reduces vibration and abnormal noise. The offset of the center of gravity of the roller tube 100 reduces the vibration amplitude of the middle part. Even when the vehicle is driving on an uneven road or the door is closed, the abnormal noise caused by the vibration of the roller tube 100 can be significantly reduced.

[0021] A counterweight 200 is added inside the reel 100. The counterweight 200 changes the position of the center of gravity of the reel 100 so that the center of gravity of the reel 100 is located at the position of the counterweight 200. When the vehicle bumps or the door is closed, the vibration position of the reel 100 is concentrated at the center of gravity, and the center of gravity of the reel 100 is away from its middle position and close to the axial joint of the reel 100, so the vibration and abnormal noise generated by the reel 100 can be reduced.

[0022] On the basis of the above-mentioned embodiment, the counterweight 200 is a tubular structure, and the counterweight 200 is installed inside the coiled tube 100. This design realizes the center of gravity adjustment in a concealed manner, and also makes full use of the internal space, avoiding the impact on the appearance and installation space. In addition, the tubular counterweight 200, as an internal structural member, can enhance the overall rigidity of the coiled tube 100, and improve the structural strength of the coiled tube 100 to a certain extent. In addition, the counterweight 200 is designed to be tubular, which is convenient for direct embedding during the manufacturing or assembly process of the coiled tube 100, without the need for complicated later addition steps, simplifying the production process, and reducing the difficulty and cost of assembly.

[0023] like Figure 1 , Figure 3 As shown, based on the above embodiment, the interior of the roller tube 100 is filled with a sound-absorbing sponge. The sound-absorbing sponge can effectively absorb and reduce the noise generated by the vibration of the roller tube 100 during the driving of the vehicle. In addition, by filling the sound-absorbing sponge, the structural strength of the roller tube 100 can be improved to a certain extent and its deflection can be reduced.

[0024] like Figure 2-3 As shown, on the basis of the above embodiment, a curtain frame 300 is further included, and the roller tube 100 is installed in the curtain frame 300. The curtain frame 300 provides a stable installation platform and support frame for the roller tube 100.

[0025] On the basis of the above embodiment, side covers 310 are provided on both sides of the curtain frame 300, and the two ends of the roller tube 100 are respectively axially connected to the two side covers 310. The side covers 310 are part of the curtain frame 300, and the axial connection design between the side covers 310 on both sides of the curtain frame 300 and the two ends of the roller tube 100 enables the roller tube 100 to rotate relative to the axial covers.

[0026] On the basis of the above embodiment, a reset torsion spring 110 is further included. The reset torsion spring 110 is arranged in the reel 100. One end of the reset torsion spring 110 is connected to the reel 100 and the other end is connected to one of the side covers 310. The introduction of the reset torsion spring 110 is designed to further improve the convenience and automation of the sunshade. When the sunshade is pulled out and unfolded, the torsion spring will store energy due to being stretched. Once the sunshade is released, the torsion spring will use the stored energy to automatically roll the curtain back into the reel 100 to achieve automatic reset. The reset torsion spring 110 is arranged inside the reel 100, does not occupy additional space, and ensures the compactness of the sunshade structure.

If the specific posture changes, the directional indication will also change accordingly.

[0028] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features.
