Description

Technical Field

[0001] The utility model relates to the technical field of vehicle accessories, specifically a fixed-wing rearview mirror. Background Art

[0002] The rearview mirror is a standard configuration of automobiles and has evolved continuously in the development process of automobiles. The initial rearview mirror was just a simple plane mirror, which could provide a certain rear view, but had problems such as limited field of view and image distortion. With the continuous progress of technology, the types of rearview mirrors have gradually become rich, and convex mirrors, dual-curvature mirrors, etc. have emerged, greatly improving the field of view and image quality. However, limited by its size and installation position, the field of view is relatively limited. With the booming development of electronic technology, electronic rearview mirrors have emerged. The electronic rearview mirror collects images of the rear of the vehicle through a camera and displays them on the display screen in the vehicle. This kind of rearview mirror has the advantages of a wide field of view, clear images, adjustable viewing angles, etc., and can also provide a better view under bad weather conditions. However, when the shape is too large, it will also increase the unnecessary wind resistance coefficient. Summary of the Utility Model

[0003] The purpose of the utility model is to solve the problems existing in the prior art, and provide a fixed-wing rearview mirror, which can reduce the windward area on the basis of providing a basic view, reduce the wind resistance problem caused by a large volume; and at the same time provide a downward pressure on the moving vehicle.

[0004] In order to achieve the above object, the utility model is realized through the following technical solutions:

[0005] The fixed-wing rearview mirror includes a connecting arm and a windward shell fixed at one end of the connecting arm. A camera is arranged in the windward shell. A windward head is arranged at the front end of the windward shell, and the outer diameter of the windward head increases sequentially from front to back. The upper surface of the connecting arm is a curved surface protruding upward, and the lower surface of the connecting arm is a curved surface protruding downward. The front end of the upper surface of the connecting arm coincides with the front end of the lower surface of the connecting arm, and the rear end of the upper surface of the connecting arm coincides with the rear end of the lower surface of the connecting arm. The curvature of the lower surface of the connecting arm is greater than the curvature of the upper surface of the connecting arm.

[0006] Preferably, both the windward shell and the windward head are of revolution.

[0007] Preferably, the windward head is in the shape of a bullet head.

[0008] Preferably, the connecting arm is fixed on the vehicle body, and the angle between the connecting arm and the vehicle body is adjustable.

[0009] Preferably, an installation groove adapted to the camera is arranged at the rear end of the windward shell. The depth of the installation groove is greater than the length of the camera, and a shielding part for the camera is naturally formed at the rear end of the installation groove.

[0010] Preferably, the outer diameter of the windward shell is greater than the maximum thickness of the connecting arm.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] 1. By arranging a windward head at the front end of the windward shell for installing a camera, the present utility model can further reduce wind resistance. The windward shell, windward head, and connecting arm are all smooth, which will not cause more turbulent flows. The connecting arm adopts a curved surface with different upper and lower curvatures. Since the curvature of the lower surface of the connecting arm is greater than that of the upper surface, the air flow velocity at the lower surface is fast and the pressure is small, while the air flow velocity at the upper surface is fast and the pressure is large. When the air flow passes through the upper and lower surfaces of the connecting arm, due to the protrusion of the lower surface, the flow tube below is compressed, while the upper surface is relatively flat and the flow tube expands. According to the continuity principle, this results in a greater flow velocity on the lower surface of the connecting arm than on the upper surface. Then, according to Bernoulli's principle, a downward force is generated, thereby enabling the vehicle body to better adhere to the ground and improving the power and stability of the vehicle to a certain extent.

[0013] 2. The tail of the windward shell of the present utility model protrudes beyond the mirror surface of the camera, which can effectively prevent raindrops from splashing onto the camera and causing safety problems due to unclear camera images.

[0014] 3. By adjusting the angle between the connecting arm and the vehicle body according to different vehicle speeds and making different downward force adjustments for the vehicle at different speeds, the best vehicle driving performance and stability can be achieved.

[0018] The present utility model will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present utility model and not to limit the scope of the present utility model. In addition, it should be understood that after reading the content taught by the present utility model, those skilled in the art can make various changes or modifications to the present utility model, and these equivalent forms also fall within the scope defined by the present application.

[0019] Embodiment: As shown in the attached Figure 1-2As shown in the figure, the present utility model relates to a fixed-wing rearview mirror, which can reduce the air resistance brought by traditional automotive rearview mirrors, provide a certain amount of downward pressure, and complete the observation of the rear and side-rear of the vehicle through a camera installed inside. It includes a connecting arm 1 and a windward shell 2 fixed at one end of the connecting arm 1. A camera 21 is provided inside the windward shell 2. The camera 21 can adopt the camera of an existing electronic rearview mirror. A windward head 3 is provided at the front end of the windward shell 2, and the outer diameter of the windward head 3 increases sequentially from front to back. The windward head 3 can reduce wind resistance. Preferably, both the windward shell 2 and the windward head 3 are of a rotational body, and an integral structure can be adopted between the windward shell 2 and the windward head 3, which is integrally formed. The windward shell 2 can adopt a cylindrical shell, and the shape of the windward head 3 can be conical.

[0020] Preferably, the outer diameter of the windward shell 2 is greater than the maximum thickness of the connecting arm 1. Both the front part of the windward shell 2 and the rear part of the windward head 3 are fixedly connected to the connecting arm 1. An integral structure can be adopted among the connecting arm 1, the windward shell 2, and the windward head 3.

[0021] The connecting arm 1, the windward shell 2, and the windward head 3 are smooth throughout, and will not cause more turbulent flows.

[0022] The connecting arm 1 or the whole of the connecting arm 1, the windward shell 2, and the windward head 3 can form a fixed wing. The present utility model combines the fixed wing with an electronic rearview mirror.

[0023] Preferably, the windward head 3 is in the shape of a bullet head.

[0024] Preferably, an installation groove adapted to the camera 21 is provided at the rear end of the windward shell 2. The depth of the installation groove is greater than the length of the camera 21. A shielding portion of the camera 21 is formed at the rear end of the installation groove. The tail of the windward shell 2 protrudes from the camera mirror surface, effectively avoiding raindrops from splashing onto the camera and causing safety problems due to unclear camera images.

[0025] The upper surface of the connecting arm 1 is a curved surface that bulges upward, and the lower surface of the connecting arm 1 is a curved surface that bulges downward. Moreover, the front end of the upper surface of the connecting arm 1 coincides with the front end of the lower surface of the connecting arm 1, and the rear end of the upper surface of the connecting arm 1 coincides with the rear end of the lower surface of the connecting arm 1. The curvature of the lower surface of the connecting arm 1 is greater than the curvature of the upper surface of the connecting arm 1. The connecting arm 1 adopts curved surfaces with different upper and lower curvatures. In this part, since the curvature of the lower surface of the connecting arm 1 is greater than that of the upper surface, the air flow velocity at the lower surface is fast and the pressure is small, while the air flow velocity at the upper surface is fast and the pressure is large. When the air flow passes through the upper and lower surfaces of the connecting arm 1, due to the bulge of the lower surface of the connecting arm 1, the lower flow tube is compressed, while the upper part is relatively flat and the flow tube expands. According to the continuity principle, this results in a higher flow velocity on the lower surface than on the upper surface. Then, according to Bernoulli's principle, a downward pressure is generated, thereby enabling the vehicle body to better adhere to the ground and improving the power and stability of the vehicle to a certain extent.

[0026] Preferably, the connecting arm 1 is fixed to the vehicle body, and the angle between the connecting arm 1 and the vehicle body is adjustable. According to different vehicle speeds, the angle between the connecting arm 1 and the vehicle body is adjusted to adjust the downforce of the vehicle at different speeds, so as to achieve the best driving performance and stability of the vehicle. Further, the vehicle body and the connecting arm can be adjusted in multiple segments to achieve the downforce matching at different speeds. The connecting arm 1 can be connected to the vehicle body by using an existing rearview mirror connecting piece, or the connecting arm 1 can also be made of a bendable material.
