Description

Technical Field

[0001] This utility model relates to the field of automotive rear wing technology, and specifically discloses a carbon fiber composite automotive rear wing. Background Technology

[0002] A car spoiler, also known as a rear wing, is an aerodynamic component installed at the rear of a car to improve the vehicle's stability and handling at high speeds. It generates downward pressure by altering the direction and speed of airflow, thereby increasing the contact area between the tires and the ground and improving grip.

[0003] Car rear spoilers are typically designed based on aerodynamic principles and come in various shapes, including ducktail, fixed, and adjustable types. For example, utility model patent CN208978974U discloses an adjustable-angle car rear spoiler, comprising a base with two bolts on its left and right sides. Each bolt is fitted with a washer, and the bolts are threaded onto a second nut. The base is fixed to the upper part of the trunk lid by the bolts and washer. A housing is located at the upper end of the base, and a stepper motor is mounted on the inner wall of the housing. The stepper motor is connected to a first gear, which in turn is connected to a second gear. The second gear is fitted onto a lead screw, the lower end of which passes through a bearing and connects to the second gear. The bearing is fixed inside the housing on the opposite side from the motor. The lead screw is threaded onto a nut, and a stop plate is located at the upper end of the lead screw. A guide post is located on the upper side of the nut. This utility model, by adjusting the angle of the car rear spoiler, alters the airflow during car movement, improving the car's stability while driving. Currently, the wing modifications added to the rear of vehicles are divided into two categories: fixed-angle installations and adjustable-angle installations. Adjustable wing installations are more suitable for long-term high-speed driving, as they can adjust the wing angle according to actual wind speed, improving airflow smoothness and ensuring tire grip. However, most wing adjustment structures are mainly mechanical, adjusting the wing angle through bolt tightening, etc. But this kind of adjustment cannot be switched at any time while driving. Some also add electric drive for auxiliary adjustment, but this type of electrical adjustment equipment is connected to the vehicle's main power supply. For the currently popular electric vehicles, the frequent switching of wing angles greatly increases the main power consumption and reduces the vehicle's range. At the same time, most wings are made of metal or pure plastic materials, with simple structure, low compressive strength, and metal materials are also prone to rust, affecting the durability of the wing. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a carbon fiber composite car tail wing to solve the problem that the wing can be angled while driving. At the same time, it can adjust the power supply of the wing drive components without using the main power supply. Furthermore, it improves the shortcomings of the traditional single structure of the wing and enhances the wing's pressure resistance.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a carbon fiber composite car rear wing, comprising a base assembly, wherein a rear wing assembly is disposed above the base assembly, and the base assembly and the rear wing assembly are driven by a transmission assembly.

[0006] The base assembly includes a housing one and a housing two;

[0007] The tail fin assembly includes a bearing, a shaft, a rod sleeve, a tail fin plate, and a tail fin wing.

[0008] The transmission assembly includes a motor.

[0009] Furthermore, both the outer shell 1 and the outer shell 2 are rectangular shell structures. The inner cavity 1 is provided inside the outer shell 1, and the inner cavity 2 is provided inside the outer shell 2. The opening positions of the inner cavity 1 and the opening positions of the inner cavity 2 are both covered by a base. A cable routing hole is opened in the middle of the base and passes through its interior. Mounting plates are respectively provided on both sides of the base. Mounting holes are opened on the surface of the mounting plates and pass through their interiors. The same cable routing pipe is provided through the outer shell 1 and the outer shell 2. The interior of the cable routing pipe is connected to the inner cavity 1 and the inner cavity 2 respectively.

[0010] Furthermore, a bearing is provided above both the outer casing 1 and the outer casing 2. The two bearings distributed along both sides are provided with the same shaft through their interiors. The surface of the shaft is interference-fitted with the inner ring wall of any one of the bearings. A sleeve is provided on the surface of the shaft.

[0011] Furthermore, the surface of the rod sleeve is provided with a tail fin plate, and a number of tail fins are respectively provided on the upper end of the tail fin plate. The tail fins are located on both sides and the middle of the upper end of the tail fin plate, and the spacing between adjacent tail fins is the same.

[0012] Furthermore, a photovoltaic power generation panel is provided above the tail fin, and the photovoltaic power generation panel is embedded in the upper end of the tail fin. A power generation control device is provided inside the inner cavity. A solar controller, a battery and an inverter are respectively installed inside the housing of the power generation control device. The photovoltaic power generation panel, the solar controller, the battery and the inverter are connected to each other by wires.

[0013] Furthermore, the tail fin is composed of a waterproof layer, an anti-ultraviolet layer, and a core layer in sequence. The waterproof layer contains an anti-ultraviolet layer, and the anti-ultraviolet layer contains a core layer.

[0014] Furthermore, the motor is located inside the inner cavity two, and a drive shaft is installed inside the motor. A bearing two is installed through one side of the outer shell two, and the end of the shaft away from the motor extends outward through the bearing two. The surface of the shaft is interference-fitted with the inner ring wall of the bearing two.

[0015] Furthermore, one end of the shaft is provided with an extension shaft, a linkage gear is provided through the surface of the extension shaft, and a drive gear is provided through the outer end of the shaft, with the drive gear and the linkage gear meshing with each other.

[0016] The working principle and beneficial effects of this solution are as follows: 1. The tail wing plate and tail wing fin in the tail wing assembly of this solution can effectively change the airflow direction, reduce the lift generated when the vehicle is traveling at high speed, thereby increasing the contact pressure between the tire and the ground and enhancing the grip. The uniform distribution of the tail wing fin further optimizes the tail airflow, reduces turbulence and air resistance, and improves the overall aerodynamic efficiency. In addition, the tail wing plate adopts a multi-layer composite structure. The carbon fiber core layer has high strength while ensuring lightweight. The addition of the UV-resistant layer and waterproof layer extends the service life of the tail wing.

[0017] 2. As described in point 1, the tail wing adopts a photovoltaic power generation structure, achieving energy self-sufficiency. It does not require the use of the vehicle's main power supply. It converts solar energy into electrical energy and stores it in the battery to provide power for the motor drive, reducing dependence on the vehicle's main power supply. The solar controller, inverter and other components in the power generation control device ensure the stability of the power conversion. At the same time, the driver can directly control the tail wing angle adjustment through the switch in the cab. The operation is convenient and does not require additional fuel power.

[0026] The following detailed description illustrates the specific implementation method:

[0027] Example

[0028] like Figures 1 to 6 As shown, a carbon fiber composite car rear wing is disclosed, including a base component 1, a rear wing component 2 disposed above the base component 1, and the base component 1 and the rear wing component 2 are driven by a transmission component 3.

[0029] The base assembly 1 includes a first housing 10 and a second housing 11;

[0030] The tail fin assembly 2 includes a bearing 20, a shaft 21, a rod sleeve 22, a tail fin plate 23, and a tail fin 24;

[0031] The transmission assembly 3 includes a motor 30.

[0032] Both outer shell 10 and outer shell 2 11 are rectangular shell structures. Outer shell 10 has an inner cavity 12, and outer shell 2 11 has an inner cavity 2 13. The openings of inner cavity 12 and inner cavity 2 13 are covered by bases 14. The bases 14 are fixed to the corresponding ends of the outer shells with screws. Sealant is applied to the joint between the bases 14 and the outer shells. A cable routing hole 15 is provided in the middle of the base 14, penetrating its interior. Mounting plates 16 are provided on both sides of the base 14. The mounting plates 16 are connected to the bases 14. The connection points are fixed by welding. Mounting plate 16 has mounting holes 17 penetrating its interior. The inner wall of mounting hole 17 is smooth or threaded. A common conduit 18 runs through the outer shell 10 and outer shell 2 11. The conduit 18 communicates with inner cavity 12 and inner cavity 2 13 respectively. The connection points between conduit 18 and outer shells 10 and 2 11 are fixed by welding. Outer shell 10, outer shell 2 11, base 14, and mounting plate 16 are all made of stainless steel with a galvanized coating. The layer provides rust and stain protection for stainless steel. When adding a rear spoiler to the rear of a vehicle, it needs to be installed at a fixed point using the base component 1. The mounting plate 16 at the lower end of the outer shell 10 and the outer shell 2 11 fits into the mounting point at the rear of the car, and a hole is made in the rear hood to connect it to the wiring hole 15, so that the wiring of the motor 30 or the solar energy storage component can be connected to the cab. After the mounting plate 16 is attached to the car surface, it is also sealed and reinforced with sealant. At the same time, holes are made in the car surface for mounting plate 16, so that bolts can pass through the mounting hole 17 and the car, and are fixed from the inside by the bolt end with nuts to ensure the installation of mounting plate 16 is stable. This further improves the stability of the rear spoiler after installation. The wiring tube 18 can be used to connect the two inner cavities, so that the wiring of the equipment in the two inner cavities will not be exposed. At the same time, the wiring tube 18 further improves the connection strength between outer shell 10 and outer shell 2 11, making the connection with the car body more secure during driving.

[0033] Bearing 20 is provided on the top of both outer casing 10 and outer casing 11. The outer ring wall of bearing 20 is fixed to the corresponding outer casing by screws. The same shaft 21 is provided through the interior of the two bearings 20 distributed on both sides. The surface of shaft 21 is interference-fitted with the inner ring wall of any one of the bearings 20. A sleeve 22 is provided on the surface of shaft 21. The connection position between the sleeve 22 and shaft 21 is fixed by screws. Shaft 21 can rotate based on bearing 20. During the rotation of shaft 21, the sleeve 22 can rotate synchronously.

[0034] The surface of the sleeve 22 is provided with a rear wing 23. The connection between the rear wing 23 and the sleeve 22 is fixed by screws. Several rear wing fins 24 are provided on the upper end of the rear wing 23. The rear wing fins 24 are located on both sides and the middle of the upper end of the rear wing 23. The spacing between adjacent rear wing fins 24 is the same. By changing the direction of airflow, the rear wing 23 can reduce the lift generated by the vehicle when driving at high speed. Reducing lift helps to increase the contact pressure between the tire and the ground, thereby improving the vehicle's grip and stability. The rear wing fins 24 can further change the direction of airflow, generating additional downforce, thereby further reducing lift and improving vehicle stability. The rear wing fins 24 can also more precisely control the airflow, reducing turbulence and drag at the rear, thereby improving aerodynamic performance.

[0035] A photovoltaic power generation panel 2001 is installed above the tail fin 23. The photovoltaic power generation panel 2001 is embedded in the upper end of the tail fin 23. During the manufacturing process of the tail fin 23, a recess is left for the placement of the photovoltaic power generation panel 2001. The photovoltaic power generation panel 2001 and the tail fin 23 are connected by screws, and the joint is sealed with sealant to prevent rainwater from penetrating into the recess and intruding into the interior of the photovoltaic power generation panel 2001. A power generation control device 2002 is installed inside the inner cavity 12. The housing of the power generation control device 2002 contains a solar controller, a battery, and an inverter. The photovoltaic power generation panel 2001, the solar controller, the battery, and the inverter are interconnected by wires. The inverter is also connected to the motor 30 and the control room to operate the motor 30. The active switch is connected in parallel via wires. When generating electricity without using the vehicle's main power supply, the photovoltaic panel 2001 converts solar energy into direct current through the photovoltaic effect. The generated direct current is transmitted to the solar controller in the power generation control device 2002 via wires. The solar controller is responsible for managing the input and output of electrical energy to ensure the safety and stability of electrical energy. It also has functions such as overcharge protection, over-discharge protection, and short circuit protection to protect the battery and the entire system. The electrical energy managed by the solar controller is transmitted to the battery for storage. The battery can provide power when there is insufficient sunlight or at night to ensure the continuous power supply of the system. When electrical energy is needed, the direct current in the battery is transmitted to the inverter via wires, and the inverter converts the direct current into alternating current.

[0036] The rear wing 23 is composed of a waterproof layer 2301, an anti-ultraviolet layer 2302, and a core layer 2303. The anti-ultraviolet layer 2302 is wrapped inside the waterproof layer 2301, and the core layer 2303 is wrapped inside the anti-ultraviolet layer 2302. The core layer 2303 is made of carbon fiber material. Carbon fiber has extremely high strength and can withstand large stress and impact. The low density of carbon fiber can significantly reduce the weight of the rear wing and improve the vehicle's fuel efficiency and performance. The anti-ultraviolet layer 2302 is made of benzophenone, benzotriazole, or triazine compounds, which can absorb ultraviolet rays and prevent them from degrading the carbon fiber. The waterproof layer 2301 is made of polyvinyl chloride membrane material, which has good corrosion resistance and waterproof effect, and can protect the core layer 2303 from water erosion and prevent rainwater from penetrating into the carbon fiber. The structure of the rear wing 24 is the same as that of the rear wing 23.

[0037] The motor 30 is located inside the inner cavity 13. The outer wall of the motor 30 is fixedly mounted to the inner wall of the inner cavity 13 via a bracket. A forward / reverse switch (HY2-8) is installed in the driver's cab to control the motor 30's forward / reverse rotation and to start / stop it. The motor 30 has a drive shaft 31 inside, and it also functions as a brake motor, containing an electromagnetic brake. The electromagnetic brake is a common locking device that uses electromagnetic principles to quickly lock the shaft 31 when the motor 30 is de-energized. When the motor 30 is energized, the electromagnetic coil generates a magnetic field, causing the brake's friction pads to separate from the brake disc, allowing the motor 30 to rotate freely. When the motor 30 is de-energized, the electromagnetic coil loses its magnetism, and the spring or other mechanical device presses the friction plate against the brake disc, thereby locking the shaft 31 and achieving a locking effect. By locking the shaft 31 after the power is off, the tail wing can maintain its current angle when the angle is adjusted or not. A bearing 32 is provided through one side of the outer shell 11. The end of the shaft 31 away from the motor 30 extends outward through the bearing 32. The surface of the shaft 31 is interference-fitted with the inner ring wall of the bearing 32. The bearing 32 is a sealed bearing, which can prevent rainwater from seeping into the interior of the outer shell 11 through the bearing 32 when the shaft 31 rotates normally.

[0038] An extension shaft 34 is provided at one end of the shaft 21. The connection between the extension shaft 34 and the shaft 21 is fixed by welding. A linkage gear 35 is provided through the surface of the extension shaft 34. The connection between the linkage gear 35 and the extension shaft 34 is fixed by screws. A drive gear 33 is provided through the outer end of the rotating shaft 31. The connection between the drive gear 33 and the rotating shaft 31 is fixed by screws. The drive gear 33 and the linkage gear 35 are meshed with each other. When the angle of the tail wing 23 needs to be adjusted, the battery of the solar power generation structure is powered and the inverter performs DC-AC conversion to power the drive of the motor 30. The motor 30 can be started by the forward and reverse switch in the main cockpit. The forward and reverse switch can drive the rotating shaft 31, so that the drive gear 33 can mesh with the linkage gear 35 to rotate. In turn, the extension shaft 34 and the shaft 21 can rotate, and finally drive the tail wing 23 to adjust the pitch angle.

[0039] In practice

[0040] The base component 1 of this solution is fixed to the rear of the car through the mounting plate 16 of the outer shell 10 and the second outer shell 11. The mounting holes 17 on the surface of the mounting plate 16 are connected to the car body by bolts to ensure the stability of the rear wing. The joint between the base 14 and the outer shell 10 and the second outer shell 11 is coated with sealant to prevent rainwater from seeping into the inner cavity 12 and the inner cavity 23. The design of the wiring hole 15 and the wiring tube 18 allows the wiring of the motor 30 and the photovoltaic power generation panel 2001 to be concealed and avoid exposure damage. The outer shell 10, the second outer shell 11, the base 14 and the mounting plate 16 are all made of galvanized stainless steel, which has both rust resistance and structural strength to ensure durability in long-term use. The wiring tube 18 is not only used for wiring connection, but also enhances the connection strength between the outer shell 10 and the second outer shell 11, making the rear wing more firmly attached to the car body during high-speed driving.

[0041] The rear wing assembly 2 supports the shaft 21 via the bearing 20, allowing the rear wing plate 23 to rotate around the shaft. The rear wing fins 24 on the surface of the rear wing plate 23 are distributed at specific intervals to precisely guide airflow, reduce turbulence at the rear of the vehicle, and reduce air resistance. The carbon fiber core layer 2303 provides high-strength support while reducing overall weight. The waterproof layer 2301 and the UV-resistant layer 2302 protect the core layer 2303 from environmental corrosion. When the vehicle is traveling at high speed, the rear wing plate 23 and the rear wing fins 24 work together to change the direction of airflow, generate downforce, counteract lift, and enhance tire grip.

[0042] The motor 30 drives the gear 33 to rotate via the shaft 31. The meshing linkage gear 35 drives the extension shaft 34 and the shaft 21 to rotate, ultimately adjusting the pitch angle of the rear wing 23. The brake motor 30 has a built-in electromagnetic brake. When the power is off, the friction plate locks the shaft 31 to fix the rear wing angle. The bearing 32 adopts a sealed design to prevent rainwater from entering the inner cavity 13. The forward and reverse switch in the driver's cab controls the start, stop and turn of the motor 30, realizing real-time adjustment of the rear wing 23. The solar power generation system provides auxiliary power to the motor 30, reducing the dependence on the vehicle's main power supply.

[0043] The above description is merely an embodiment of this utility model, and common knowledge such as specific structures and characteristics in the solution is not described in detail here. It should be noted that those skilled in the art can make several modifications and improvements without departing from the structure of this utility model, and these should also be considered within the protection scope of this utility model. These modifications and improvements will not affect the effectiveness of the implementation of this utility model or its practicality.
