[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 This utility model provides an implementation scheme: the current fairing material adopts a lightweight structure, which reduces the fairing's ability to resist external impacts. At the same time, the fairing suffers greater air resistance at high speeds. Because of its light weight, the fairing is very prone to vibration, which increases the vehicle's wind resistance and causes breakage at connection points, affecting driving safety.

[0020] According to the instruction manual Figure 1-3 As can be seen, in order to ensure the structural stability of the lightweight fairing and reduce the vibration problem caused by wind resistance during high-speed driving, this application discloses a lightweight fairing assembly structure, including a fairing shell 1. The fairing shell 1 is a streamlined cavity shell, which forms a composite bending resistance system with the support frame 2. The support frame 2 is set in close contact with the inner wall of the fairing shell 1 and adopts a multi-directional stiffener network structure. The main beam section is I-shaped and the transverse stiffener spacing is gradient distributed to achieve uniform load transfer.

[0021] To ensure the stability of the diffuser at high speeds, this application also discloses a stable connection structure. The connector 3 of the stable connection structure is rigidly connected to the vehicle body by high-strength bolts. The connector 3 adopts an aluminum alloy frame, which has the characteristics of high structural strength and light weight. The stabilizer bar 4 adopts a hollow vibration damping design. The control groove 5 inside the stabilizer bar 4 has a built-in connector seat. During installation, the plug rod 6 is inserted into the stabilizer bar 4 and threadedly connected to the connector seat. On the one hand, the connector 3 is connected to the fairing shell 1 through the plug rod 6. On the other hand, the multi-point plug rod 6 structure can ensure more stable installation of the fairing shell.

[0022] As a preferred option, triangular reinforcing plates 8 are provided on both sides of the stabilizer bar 4 and welded to the connector 3 to form a triangular support structure, which significantly improves the lateral load-bearing capacity. The front end of the fairing is provided with positioning holes 9, which are precisely matched with the fixing holes of the connector 3 through anti-loosening bolts to ensure installation stability.

[0023] As a preferred option, the pair of movable slots 7 of the supporting frame 2 extend through the top of the rectifier housing, and a rotating seat 11 with a shock-absorbing pad is set at the top of the insert rod 6. The hexagonal rotating slot design facilitates installation and adjustment. The insert rod 6 and the connecting seat are connected by a threaded locking connection, and with the guiding structure of the movable slots 7, dynamic displacement compensation is achieved to avoid stress concentration.

[0024] As a preferred option, the connection between the stabilizer bar 4 and the connecting body 3 is further strengthened by multiple sets of reinforcing plates 8 to disperse vibration energy, and an elastic buffer layer is provided on the contact surface between the support frame 2 and the fairing shell 1 to absorb local deformation stress.

[0025] As a preferred option, the shock-absorbing pad at the end of the insertion rod 6 adopts a ring-shaped multi-layer composite structure, which fits with the movable groove 7 with a gap. This can suppress high-frequency vibration and allow low-speed deformation displacement, thereby improving the durability of the connection part.

[0026] As a preferred option, the streamlined cavity of the fairing 1 and the supporting frame 2 form a synergistic wind resistance structure. The aerodynamic shape is optimized to reduce air turbulence, while the internal frame network is used to enhance bending resistance, thus comprehensively solving the contradiction between lightweight and structural rigidity.

[0027] In summary, this lightweight fairing, with its fairing shell 1 and supporting frame 2 forming a composite bending resistance system through a multi-directional stiffener network, and its I-beam main beam combined with gradient transverse stiffeners to improve load transfer efficiency, and its stable connection structure with the threaded locking of the insert rod 6 and the connecting seat, and the hollow vibration reduction design of the stabilizer rod 4 to achieve multi-point dynamic anchoring, effectively disperses high-speed wind resistance and suppresses vibration, and the triangular reinforcing plate 8 strengthens the transverse bearing capacity of the connecting body 3, comprehensively solving the problems of insufficient structural rigidity and easy connection damage under the premise of lightweight design.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
