Description

Technical Field

[0001] This application belongs to the field of electric vehicle parts technology, specifically relating to an electric vehicle fairing with side-discharge airflow. Background Technology

[0002] A fairing is a specialized component on an electric vehicle used to reduce wind resistance. Without a fairing, wind resistance increases power consumption, resulting in a less durable battery, more frequent charging, and a negative impact on the riding experience.

[0003] There are two problems with the fairings on existing electric vehicles: 1. Fairings are generally smooth curved surfaces. During riding, the airflow is directed from all four directions: up, down, left, and right. While the airflow from the left and right directions effectively reduces wind resistance, the airflow from the top and bottom still applies wind resistance to the rider's body; 2. Fairings usually have the manufacturer's logo or trademark on them. Currently, logos are fixed to the fairing with screws or glued with environmentally friendly adhesive. Adhesive is prone to failure under rain and sun exposure. Screws can create protrusions on the fairing, affecting the airflow and the overall appearance of the vehicle. Utility Model Content

[0004] In view of this, this application provides a side-discharge electric vehicle fairing to solve all or part of the technical problems described in the background section of this application.

[0005] The innovative ideas of this application are as follows: 1. By changing the structure of the fairing body, the wind force is directed to both sides of the fairing to avoid being applied to the rider's body and forming secondary wind resistance; 2. By setting a sign slot on the fairing body and using screw signs and internal locking components, a seamless connection is achieved between the sign and the fairing body, so that the outer surface of the sign becomes part of the airflow guiding surface, which neither affects the aesthetics nor the airflow guiding effect.

[0006] The solution provided in this application to solve its technical problem is as follows:

[0007] A side-venting electric vehicle fairing includes a fairing body with a smooth arc-shaped surface structure; wind deflectors are provided at the top and bottom edges of the fairing body, and side vents are provided at the left and right edges of the fairing body; the side vents are located between the wind deflectors at the top and bottom of the fairing body.

[0008] Preferably, the fairing body is also provided with a nameplate receiving groove, which is used to install screw nameplates.

[0009] Preferably, a screw hole is provided on the bottom of the sign receiving groove, which is used to pass through and receive the screw part of the screw sign.

[0010] Preferably, the electric vehicle fairing with air vents on both sides also includes a screw sign and an inner locking component; the screw sign includes a sign body and an integral screw disposed inside the sign body; the sign body has an arc and shape that matches the sign receiving groove.

[0011] Preferably, the inner locking component includes a nut portion and a connecting portion; the nut portion is used to connect the integrated screw, and the connecting portion is used to fix the electric vehicle fairing with air deflectors on both sides to the electric vehicle frame.

[0012] Preferably, the nut part has a threaded hole that passes through the inner locking component; the connecting part has a cone structure with a conical assembly cavity inside.

[0013] Preferably, the integral screw passes through the screw hole and connects to the nut.

[0014] Preferably, the signage receiving slot has a polygonal structure.

[0015] As a preferred option, the windshield strip and the fairing body are integrally molded.

[0016] Beneficial technical effects:

[0017] 1. By setting upper and lower wind deflectors at the top and bottom of the fairing body, and side air vents on the left and right sides of the fairing body, wind resistance can be removed from both sides of the fairing body, preventing the airflow from the top and bottom from being applied to the rider's body and creating secondary wind resistance.

[0018] 2. By setting a nameplate receiving groove on the body of the air guide and using a screw nameplate with a matching arc surface and curvature, a seamless connection can be achieved between the nameplate and the air guide, which neither affects the aesthetics nor the air guiding effect.

[0019] The technical solution and technical effects of this application will be described in detail below with reference to the accompanying drawings and specific embodiments. Attached Figure Description

[0028] Please see Figures 1-2 The electric vehicle fairing with side air deflectors disclosed in this application includes a fairing body, a screw label 4, and an inner locking component 5.

[0029] The fairing body has a smooth, curved surface structure. Wind deflectors 1 are provided at the top and bottom edges of the fairing body, and side air vents 2 are provided at the left and right edges of the fairing body; the side air vents 2 are located between the upper and lower wind deflectors 1 at the top and bottom of the fairing body. The wind deflectors 1 and the fairing body are integrally formed.

[0030] Thus, the wind resistance experienced by the fairing can be mostly guided to the side air vents 2 on both sides by the upper and lower wind deflectors 1, achieving side air venting and avoiding the wind from the top and bottom being applied to the rider's body to form secondary wind resistance.

[0031] The fairing body is also provided with a nameplate receiving groove 3, and a screw hole is provided on the bottom of the nameplate receiving groove 3. The nameplate receiving groove 3 has a polygonal structure.

[0032] The screw nameplate 4 includes a nameplate body 41 and an integral screw 42 disposed inside the nameplate body 41; the nameplate body 41 has an arc and shape that matches the nameplate receiving groove 3; after the nameplate body 41 is embedded in the nameplate receiving groove 3, its outer surface can match the arc-shaped smooth surface of the guide vane body.

[0033] The inner locking component 5 includes a nut portion 51 and a connecting portion 52; the nut portion 51 is used to connect the integrated screw 42, and the connecting portion 52 is used to fix the electric vehicle fairing with air vents on both sides to the electric vehicle frame. The nut portion 51 has a threaded hole that passes through the inner locking component 5; the connecting portion 52 has a conical structure with a tapered assembly cavity inside. The integrated screw 42 passes through the screw hole 31 and connects to the nut portion 51.

[0034] Because the sign receiving groove 3 and the sign body 41 adopt a polygonal structure, the screw sign 4 can be prevented from rotating in the sign receiving groove 3.

[0035] The fairing body is made of plastic, while the screw nameplate 4 and the inner locking component 5 are metal parts. The brand logo is displayed on the screw nameplate 4.

[0036] Explanation of principles and effects:

[0037] The integral screw 42 of the screw nameplate 4 is passed through the screw hole in the nameplate receiving groove 3 on the fairing body. Then, the screw nameplate 4 is locked into the nameplate receiving groove 3 from the inside of the fairing body through the threaded engagement between the nut part 51 and the integral screw 42. Then, the fairing is fixed to the vehicle frame as a whole through the connecting part 52.

[0038] The wind resistance encountered by the fairing during riding is relieved by the upper and lower wind deflectors 1 through the side air vents 2 on both sides of the fairing body. This side air venting prevents the airflow from the top and bottom from being applied to the rider's body and creating secondary wind resistance. At the same time, the screw-on sign, whose curvature matches the fairing, can be seamlessly connected to the sign receiving groove 3 through the inner locking component 5, without affecting the aesthetics or the airflow effect.

[0039] The technical solution and technical effects of this application have been described in detail above with reference to the accompanying drawings and specific embodiments. It should be noted that those skilled in the art can develop other embodiments based on this. Any simple modifications and equivalent substitutions that do not depart from the innovative concept of this application are covered by this application and fall within the protection scope of this patent.
