Description

Technical Field

[0001] This utility model relates to the field of automotive modification parts technology, and in particular to a carbon fiber rear wing modification strength reinforcement bracket. Background Technology

[0002] Car spoilers, as a common car modification part, can provide downforce to the vehicle at high speeds and improve handling stability. Many car owners who pursue performance and personalization will choose to modify their spoilers, especially lightweight and beautiful carbon fiber spoilers.

[0003] Currently, installing these modified rear wings usually requires the use of connecting brackets to fix the rear wing to the vehicle body. However, many of the modified brackets on the market have relatively simple structures, focusing mainly on achieving the installation function, while ignoring the fact that the rear wing will be subjected to huge wind pressure at high speeds.

[0004] This simple support structure often lacks rigidity, and under the impact of high-speed airflow, it will sway or deform slightly. This instability not only affects the aerodynamic effect of the tail wing, but also concentrates the vibration and impact force to the connection point between the tail wing and the vehicle body.

[0005] Although carbon fiber is hard, it is not tough and is particularly sensitive to concentrated stress and high-frequency vibration. Long-term vibration and stress concentration can cause fatigue damage to the carbon fiber tail fin and even cracks near the connection point, posing a safety hazard. At the same time, the simple support structure does not take into account the absorption of vibration and the effective distribution of stress.

[0006] Therefore, this utility model proposes a carbon fiber tail wing modification strength reinforcement bracket to address the shortcomings of the existing technology. Utility Model Content

[0007] In view of the problems existing in the carbon fiber tail wing retrofit strength reinforcement bracket, such as insufficient bracket rigidity, swaying under high-speed airflow, and fatigue damage to the carbon fiber tail wing caused by vibration and stress concentration, this utility model aims to provide a carbon fiber tail wing retrofit strength reinforcement bracket with an improved structure that can effectively solve the above problems.

[0008] This utility model provides a carbon fiber tail wing modification strength reinforcement bracket, including: a tail wing plate and a support mechanism, wherein the support mechanism includes a bracket for supporting the tail wing plate and a base plate installed below the bracket.

[0009] The support mechanism further includes a connector between the bracket and the base plate and a reinforcing beam installed on the rear top of the base plate. The bottom of the base plate is equipped with a shock-absorbing plate, and the two sides of the base plate are equipped with guide vanes.

[0010] Furthermore, the tail fin is provided with a flow divider at the bottom, and spoiler balls are fixed on both sides of the tail fin; the tail fin is fixedly connected to the bracket by fasteners, and a fixing plate is provided between the fasteners and the bracket; the fasteners, the fixing plate and the bracket are fixedly connected by bolts and nuts.

[0011] Preferably, the reinforcing beam has multiple heat dissipation holes.

[0012] Preferably, the flow divider has a hollow section.

[0013] Preferably, the bracket has a hollow section.

[0014] Preferably, the tail fin has an arc-shaped edge.

[0015] Preferably, the flow divider is further provided with a tapered edge.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model solves the problems of insufficient rigidity of modified tail wing brackets and swaying and deformation under high-speed airflow in the prior art by installing a reinforcing beam on the base plate and connecting the bracket and the base plate with connectors through a carbon fiber tail wing modification reinforcement bracket. This improves the installation rigidity of the tail wing and the overall structural stability.

[0018] 2. This utility model, by modifying the carbon fiber tail wing to reinforce the support, installs a shock-absorbing plate at the bottom of the base plate, and sets up airflow management components such as flow dividers, guide vanes and turbulence balls, solves the problem of fatigue damage to carbon fiber tail wings caused by vibration in the prior art and the lack of sufficient consideration for stress dispersion and airflow optimization. It can effectively absorb vibration, protect the carbon fiber structure, disperse stress and optimize aerodynamic performance. Attached Figure Description

[0025] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions in the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0026] Example:

[0027] Please refer to Figures 1 to 4 This utility model provides a carbon fiber tail wing modification strength reinforcement bracket, including a tail wing plate 1 and a support mechanism 2. The support mechanism 2 is used to support the tail wing plate 1. Spoiler balls 3 are fixedly connected to both sides of the tail wing plate 1, and a flow divider 204 is fixedly connected to the bottom of the tail wing plate 1. The tail wing plate 1 is fixedly connected to the bracket 5 of the support mechanism 2 by fasteners 4. The tail wing plate 1 is used to guide airflow, and the spoiler balls 3 are used to reduce wind resistance and protect the edge of the tail wing plate 1.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the support mechanism 2 includes a bracket 5 for supporting the tail fin 1 and a base plate 7 installed below the bracket 5. A connector 6 is fixedly connected between the bracket 5 and the base plate 7. The connector 6 is used to distribute stress. A reinforcing beam 8 is fixedly installed on the top rear side of the base plate 7. The reinforcing beam 8 is used to strengthen the overall rigidity of the base plate 7. A damping plate 202 is fixedly installed on the bottom of the base plate 7. The damping plate 202 is used to absorb and reduce vibration. Guide vanes 201 are fixedly installed on both sides of the base plate 7. The guide vanes 201 are used to guide the airflow near the base plate 7.

[0029] like Figure 4 As shown, the tail fin 1 is fixedly connected to the bracket 5 by fasteners 4. A fixing piece 9 is provided between the fasteners 4 and the bracket 5. The fasteners 4, the fixing piece 9 and the bracket 5 are fixedly connected by bolts 10 and nuts 11. This connection method ensures that the tail fin 1 and the support mechanism 2 are firmly and reliably fixed.

[0030] Please refer to Figure 1 , Figure 3 and Figure 4The diffuser 204 at the bottom of the rear wing 1 is integrally formed or fixedly connected to the rear wing 1. A first cutout 205 is formed in the diffuser 204, and a second cutout 206 is also formed in the bracket 5 of the support mechanism 2. The first cutout 205 and the second cutout 206 are through holes set in areas that do not affect the main load-bearing capacity of the diffuser 204 and the bracket 5. This hollow structure on the diffuser 204 and the bracket 5 can, while ensuring structural strength, minimize the weight of the carbon fiber rear wing modification reinforcement bracket, reduce sprung mass, and improve the vehicle's handling response. To optimize airflow and reduce stress concentration, the outer edge of the tail fin 1 is provided with an arc-shaped edge 207, and the leading or trailing edge of the splitter 204 is provided with a tapered edge 208. The arc-shaped edge 207 has a smooth transition curve, which is used to optimize the airflow passing through the edge of the tail fin 1, reduce airflow separation and vortex generation. The arc-shaped edge 207 works with the spoiler 3 to reduce wind resistance. The tapered edge 208 is wedge-shaped, which is used to reduce local stress concentration at the edge, so that the airflow force can be more smoothly distributed to the entire splitter 204, avoiding stress fracture points at sharp corners, and improving the durability and reliability of the structure.

[0031] As a preferred embodiment, please refer to Figure 1 In order to ensure airflow and aid in weight reduction, the reinforcing beam 8 of the support mechanism 2 is provided with multiple heat dissipation holes 203, which are preferably uniformly arranged through holes.

[0032] As another preferred embodiment, please refer to Figure 1 and Figure 3 In order to achieve structural lightweighting, a hollow 205 is provided in the splitter 204 at the bottom of the tail fin 1. The shape and size of the hollow 205 are determined without affecting the structural strength of the splitter 204.

[0033] As another preferred embodiment, please refer to Figure 1 and Figure 4 In order to achieve lightweight structure, the support mechanism 2 has a second hollow 206 in the bracket 5, and the second hollow 206 is located in the non-main stress area of ​​the bracket 5.

[0034] As another preferred embodiment, please refer to Figure 3 In order to optimize airflow guidance, the outer edge of the tail fin 1 is provided with an arc-shaped edge 207, which presents a smooth curved transition.

[0035] As another preferred embodiment, please refer to Figure 3 To reduce local stress concentration, the edge of the flow divider 204 is provided with a tapered edge 208, which has a smooth wedge-shaped transition.

[0036] Working principle: When the vehicle is in motion, the airflow first comes into contact with the rear wing 1. The rear wing 1 can guide the airflow and improve the vehicle's aerodynamic performance. The spoilers 3 fixed on both sides of the rear wing 1 can not only reduce wind resistance, but also protect the edge of the rear wing 1. The splitter 204 set at the bottom of the rear wing 1 is used to disperse the force of the airflow on the rear wing 1 and avoid force concentration. At the same time, the guide vanes 201 installed on both sides of the bottom plate 7 also play a role in airflow guidance and help to sort the airflow flowing near the bottom plate 7. The arc-shaped edge 207 opened on the rear wing 1 further optimizes the airflow guidance, and the conical edge 208 opened on the splitter 204 reduces local stress concentration and achieves overall airflow optimization.

[0037] The downward pressure and drag exerted by the airflow on the tail fin 1 are completely and firmly transmitted to the bracket 5 of the support mechanism 2 through the fasteners 4, fixing plates 9, bolts 10 and nuts 11. The bracket 5 then transmits the received force to the base plate 7 through the connector 6 at the lower end. The presence of the connector 6 plays a key role in stress dispersion, effectively dispersing the concentrated force to the larger base plate 7, avoiding stress concentration at the connection point between the bracket 5 and the base plate 7. To resist this force, the reinforcing beam 8 installed on the rear side of the top of the base plate 7 greatly improves the bending rigidity of the base plate 7 itself. The reinforcing beam 8 and the base plate 7 together form a T-shaped or L-shaped reinforced section, ensuring that the entire support mechanism 2 will not produce harmful deformation or swaying under huge wind pressure, thereby achieving strength reinforcement of the carbon fiber tail fin.

[0038] When the vehicle travels on uneven roads, unavoidable vibrations are transmitted from the vehicle body to the floor 7. At this time, the damping plate 202 installed at the bottom of the floor 7 comes into play. As a buffer layer, the damping plate 202 absorbs and reduces most of the direct damage to the floor 7 from vibrations, thus protecting the rigid but relatively brittle carbon fiber rear wing 1 from fatigue damage caused by high-frequency vibrations. While achieving high strength, this design also considers lightweighting. The first hollow 205 in the splitter 204 and the second hollow 206 in the bracket 5 both contribute to this. Without compromising structural strength, the structure is made lighter, reducing the additional weight brought about by the modification. In addition, the multiple heat dissipation holes 203 on the reinforcing beam 8 not only ensure airflow and reduce the wind resistance of the reinforcing beam 8 itself, but also help to achieve overall weight reduction. In summary, this utility model solves the technical problems of insufficient rigidity, easy vibration damage and stress concentration in carbon fiber tail wing modification through the synergistic effect of the reinforcing beam 8, connector 6, shock absorber 202, guide wing 201, flow divider 204, spoiler ball 3 and various optimized designs.
