Description

Technical Field

[0001] The utility model relates to an adjustable rear spoiler, belonging to the technical field of spoiler devices. Background Art

[0002] A spoiler is a device used to change the flow of a fluid (usually air). An automotive spoiler refers to a component installed on the rear trunk lid of a sedan, similar to an inverted aircraft tail wing. Some cars are equipped with a front spoiler, commonly known as an air dam, and some cars are equipped with side skirts on the sides, which are also a type of spoiler.

[0003] In the prior art, electric vehicles show a trend of great development. However, the current cruising range of electric vehicles is generally not high, which poses a certain obstacle to the popularization of electric vehicles. At present, improving the cruising range is an urgent issue. If the cruising range of general electric vehicles reaches more than 500 kilometers, it will play a greater role in promoting the popularization of electric vehicles. Reducing the air resistance of the vehicle body can reduce energy consumption, thereby increasing the cruising range. This can be used as one of the solutions to increase the cruising range. The rear spoiler is an important and effective component for increasing the grip of the vehicle's rear and reducing the air resistance of the vehicle, and is generally applied to hatchbacks and SUV models. At present, the rear spoilers on the market are basically fixed and cannot change their positions according to the dynamic conditions of the vehicle, so the optimal vehicle body stability and air resistance coefficient cannot be achieved. A few flip-up spoilers can only increase the vehicle body stability by adjusting the angle, but this increases the wind resistance, and it is difficult to make different adjustments according to different vehicle models and conditions to cope with the wind resistance. Summary of the Utility Model

[0004] The purpose of the utility model is to provide an adjustable rear spoiler that can change the angle according to the dynamic conditions of the vehicle for the above-mentioned problems.

[0005] The technical solution adopted by the utility model is as follows:

[0006] An adjustable rear spoiler includes a base fixedly installed on the vehicle body. A spoiler body is connected to the base through a first rotary lifting component and a second rotary lifting component. The first rotary lifting component and the second rotary lifting component are respectively connected to the rear side or the front side of the bottom of the spoiler body. The bottom of the first rotary lifting component is hinged to the base, and the top is slidably connected to the spoiler body. The bottom of the second rotary lifting component is slidably connected to the base, and the top is hinged to the spoiler body.

[0007] Optionally, the first rotary lifting component includes an inclined rod.

[0009] Optionally, a U-shaped frame is provided above the support bar, a cylindrical shaft is movably connected inside the U-shaped frame, one side of the cylindrical shaft is connected to a worm gear transmission, and the worm gear is connected to an inclined rod transmission through the cylindrical shaft.

[0010] Optionally, a transmission sleeve is provided on the outer surface of the cylindrical shaft, and the transmission sleeve is fixedly connected to the bottom of the inclined rod.

[0011] Optionally, a square frame is fixedly connected to the bottom of the spoiler body, and a roller is connected to the top of the oblique rod. The roller is arranged in the square frame and can move forward and backward along the square frame.

[0012] Optionally, the second rotary lifting assembly includes a support column, the bottom of which is slidably hinged to the rear of the base via a linear guide assembly, and the top of which is hinged to the front of the spoiler body.

[0013] Optionally, the linear guide rail assembly includes a support block fixedly mounted on the top of the base, a screw rod arranged in the front-to-back direction is provided inside the support block, a nut block is movably sleeved on the outer surface of the screw rod, and the nut block is hinged to the lower end of the support column; the screw rod is connected to a driving member.

[0014] Optionally, a connecting block is hinged on the top of the support column, and the upper end surface of the connecting block is fixedly connected to the bottom of the spoiler body.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. The utility model provides an adjustable rear spoiler, which is different from the traditional spoiler that can only adjust the angle. The adjustable rear spoiler of the present invention can not only achieve angle adjustment through the first rotary lifting assembly and the second rotary lifting assembly, but also can adjust the height of the front and rear sides of the bottom of the spoiler body respectively, so as to more flexibly adapt to different vehicle models and vehicle conditions.

[0018] 2. The adjustable rear spoiler provided by the present utility model can, through precise height adjustment and angle adjustment, always keep the spoiler in the optimal position according to the actual working conditions during vehicle driving, effectively increasing the grip of the vehicle's rear end, reducing air resistance, and thereby improving the cruising range of the electric vehicle, and solving the problem that most spoilers in the prior art are difficult to balance the stability and wind resistance of the vehicle body during adjustment.

Detailed implementation manners

[0026] The following will combine with the accompanying drawings to make a detailed description of the present utility model.

[0027] In order to make the purpose, technical solution and advantages of the present utility model clearer, the following will further elaborate on the present utility model in combination with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0028] An adjustable rear spoiler, as Figures 1-4 shown, includes a base 101 fixedly installed on the vehicle body. A spoiler body 2 is connected to the base 101 through a first rotary lifting assembly and a second rotary lifting assembly. The first rotary lifting assembly and the second rotary lifting assembly are respectively connected to the front side and the rear side of the bottom of the spoiler body 2. The bottom of the first rotary lifting assembly is hinged to the base 101, and the top is slidably connected to the spoiler body 2. The bottom of the second rotary lifting assembly is slidably connected to the base 101, and the top is hinged to the spoiler body 2.

[0029] The base 101 serves as the installation foundation for the entire adjustable rear spoiler body 2, bearing and fixing other components to ensure a stable connection between the spoiler body 2 and the vehicle body, guaranteeing that it will not loosen or shift under various driving conditions and providing a stable support platform for the precise adjustment of the spoiler body 2. The first rotary lifting component and the second rotary lifting component are respectively connected to the front side and the rear side of the bottom of the spoiler body 2, constituting the transmission structure for the height adjustment of the spoiler body 2. By rotating, the lifting is achieved, realizing the independent height adjustment of the front side and the rear side of the bottom of the spoiler body 2, so that the angle and the overall attitude of the spoiler body 2 can be precisely controlled to meet the aerodynamic requirements under different vehicle dynamic conditions. The hinge allows the component to rotate within a certain angle range to adapt to the angle change during the height adjustment of the spoiler body 2 and the precise control of the height of the spoiler body 2. The sliding connection can, while maintaining the transmission, allow a certain degree of displacement compensation in the horizontal direction, ensuring the smoothness and precision of the adjustment process, avoiding problems such as stress concentration or adjustment jamming caused by forced constraints between components, and at the same time ensuring the kinematic compatibility of the spoiler body 2 during the adjustment process to prevent interference or inconsistent movement. The rotation and lifting achieve the change in the height of the spoiler body 2 through the rotation of the connecting rod. This rotational movement can enable the spoiler body 2 to have a certain degree of freedom in angle change during the adjustment process. For example, when the connecting rod rotates, the spoiler body 2 can not only rise or fall but also tilt or swing to a certain extent according to the swing trajectory of the connecting rod, thus better adapting to the airflow requirements of the vehicle under different driving states. In addition, the rotation and lifting structure has more room for adjustment in the spatial layout. Since the height adjustment is achieved through the swing of the connecting rod, its driving device can be arranged in a relatively flexible position. The spoiler body 2 reasonably guides and adjusts the airflow at the rear of the vehicle by changing its own angle and height position, thereby realizing the functions of reducing air resistance and increasing the downward pressure at the rear, improving the stability and cruising range of the vehicle during driving.

[0030] Compared with the traditional spoiler body 2 that can only adjust the angle, with the setting of the first rotating lifting component and the second rotating lifting component in this solution, the height of the front side and the rear side of the bottom of the spoiler body 2 can be independently adjusted respectively, so that while changing the angle of the spoiler body 2, its position in the vertical direction of the vehicle body can also be precisely adjusted. This comprehensive adjustment ability of height and angle enables the spoiler body 2 to more flexibly adapt to the body shapes of different vehicle models and different vehicle driving conditions, and realizes the optimization of aerodynamic performance under various conditions. Since the connection methods of the bottoms of the first rotating lifting component and the second rotating lifting component to the base 101 are hinge connection and sliding connection respectively, and the connection methods to the spoiler body 2 at the tops are opposite, this structural design enables the spoiler body 2 to have a certain displacement compensation ability and adaptability during the adjustment process. When facing different vehicle models, the initial adaptive adjustment of the position of the spoiler body 2 can be realized by adjusting the lateral position of the second rotating lifting component on the base 101, and then through the separate height adjustment of the first rotating lifting component and the second rotating lifting component, the aerodynamic performance of the spoiler body 2 on the specific vehicle can be further optimized. For the same vehicle model under different vehicle conditions, this device can also maintain the best matching relationship between the spoiler body 2 and the vehicle body and the surrounding air flow through corresponding adjustment actions, and give full play to its aerodynamic function, which cannot be achieved by most of the existing fixed or simply angle-adjustable spoiler bodies 2. Through precise height and angle adjustment, the adjustable rear spoiler body 2 of this solution can realize the coordinated optimization of vehicle body stability and wind resistance under different driving states.

[0031] As another specific implementation manner, the first rotating lifting component includes an inclined rod 111. The bottom of the inclined rod 111 is hinged to the front part of the base 101 through a worm and gear assembly, and the top of the inclined rod 111 is slidably connected to the rear part of the spoiler body 2 through a sliding component. Through the cooperation of the worm and gear assembly and the inclined rod 111, the first rotating lifting component can realize the precise adjustment of the height of the rear end of the spoiler body 2, and at the same time, the angle of the spoiler body 2 can be further finely adjusted through the angle control of the worm 110 and the worm gear 104. The design of the inclined rod 111 provides a stable supporting force for the spoiler body 2, can effectively resist the air flow impact and the vibration during vehicle driving, and keeps the position of the spoiler body 2 stable. The self-locking function of the worm and gear assembly further enhances the stability of the device, prevents the spoiler body 2 from shifting in position after adjustment, ensures that the aerodynamic performance of the vehicle remains consistent during driving, and improves the driving safety and reliability. The setting of the sliding component makes the connection between the top of the inclined rod 111 and the spoiler body 2 have a certain flexibility, and can realize displacement compensation during the adjustment process, avoiding problems such as jamming or damage caused by the relative movement between components being restricted.

[0032] As another specific embodiment, the worm gear assembly includes a support bar 102 fixedly installed on the top of the base 101, a worm 104 arranged in the front-back direction is installed on one side of the support bar 102 through a fixed block 103, a limit block 105 is fixedly installed on one side of the worm 104, and a drive motor 106 is connected to the other side of the worm 104, and the drive motor 106 is arranged on the base 101; the outer surface of the worm 104 is meshed and connected with a worm wheel 110, and the worm wheel 110 is connected to the inclined rod 111 in transmission. The assembly is installed on the support bar 102 at the top of the base 101, with a reasonable layout, does not occupy too much space, and matches well with the overall structure of the vehicle, so as to facilitate the adjustment function of the spoiler body 2 in a limited space. The setting of the limit block 105 can limit the position of the worm 104 to prevent excessive rotation, and cooperate with the support bar 102 and the fixed block 103 to provide stable support for the worm gear assembly, ensuring that it maintains accurate transmission and stable operation during the working process. The high-speed rotation of the motor is converted into a low-speed high-torque output, which effectively drives the inclined rod 111 to perform lifting and angle adjustment, thereby improving the adjustment efficiency and effect, and has obvious advantages especially in large-load adjustment.

[0033] As another specific embodiment, a U-shaped frame 107 is provided above the support bar 102, and a cylindrical shaft 108 is movably connected inside the U-shaped frame 107. One side of the cylindrical shaft 108 is connected to the worm gear 110, and the worm gear 110 is connected to the inclined rod 111 through the cylindrical shaft 108. The structural design of the U-shaped frame 107 provides better support for the cylindrical shaft 108, thereby enhancing the bearing capacity of the entire transmission system. One side of the cylindrical shaft 108 is connected to the worm gear 110, and the inclined rod 111 is driven by the cylindrical shaft 108. This transmission method can effectively reduce vibration and impact during the transmission process, and improve the stability and accuracy of the adjustment.

[0034] As another specific implementation, a transmission sleeve 109 is provided on the outer surface of the cylindrical shaft 108, and the transmission sleeve 109 is fixedly connected to the bottom of the inclined rod 111. The transmission sleeve 109 serves as an intermediate connecting piece, firmly connecting the cylindrical shaft 108 and the bottom of the inclined rod 111 to form a rigid whole, thereby enhancing the rigidity of the transmission system and reducing deformation and vibration during the transmission process.

[0035] As another specific implementation manner, a square frame 112 is fixedly connected to the bottom of the spoiler body 2. A roller 113 is connected to the top of the diagonal rod 111. The roller 113 is arranged inside the square frame 112 and can move back and forth along the square frame 112. When the angle of the diagonal rod 111 is adjusted through the worm and worm gear assembly, the roller 113 can slide back and forth correspondingly inside the square frame 112, so as to adapt to the position change of the spoiler body 2 at different angles. The square frame 112 provides a clear movement track for the roller 113, restricts the movement direction of the roller 113, and enables it to move only in the front-back direction of the square frame 112.

[0036] As another specific implementation manner, the second rotating and lifting assembly includes a support column 119. The bottom of the support column 119 is slidably hinged to the rear part of the base 101 through a linear guide rail assembly. The top of the support column 119 is hinged to the front part of the spoiler body 2. The support column 119 slides along the linear guide rail on the base 101 while maintaining a certain degree of rotational freedom. The hinged connection between the top of the support column 119 and the front part of the spoiler body 2 allows the spoiler body 2 to rotate around the hinge point during the height adjustment process. Based on the restriction of the rear part of the spoiler body 2 by the first rotating and lifting assembly, the angle adjustment of the support column 119 can accurately control the lifting of the front part of the spoiler body 2, realizing the coordinated adjustment of height and angle, and enabling the spoiler body 2 to always maintain the optimal aerodynamic attitude under different working conditions.

[0037] As another specific implementation manner, the linear guide rail assembly includes a support block 114 fixedly installed on the top of the base 101. A lead screw 117 arranged in the front-back direction is provided inside the support block 114. A nut block 118 is movably sleeved on the outer surface of the lead screw 117. The nut block 118 is hinged to the lower end of the support column 119; the lead screw 117 is connected with a driving member. The transmission mode between the lead screw 117 and the nut block 118 has a high transmission efficiency and can efficiently convert the power of the driving member into the linear motion of the bottom of the support column 119.

[0038] As another specific implementation manner, a connecting block 120 is hinged to the top of the support column 119. The upper end surface of the connecting block 120 is fixedly connected to the bottom of the spoiler body 2. The upper end surface of the connecting block 120 being fixedly connected to the bottom of the spoiler body 2 provides stable support for the spoiler body 2. When the vehicle is driving at a high speed or is impacted by air flow, the connecting block 120 can effectively transmit torque and ensure the stability of the spoiler body 2.

[0039] As another specific embodiment, the second rotary lifting assembly includes two sets. One set of the lead screws 117 is connected to a second drive motor 116, and the second drive motor 116 is arranged on the base 101 through a support plate 115, or the second drive motor 116 is directly arranged on the base 101; the other set of the lead screws 117 is connected to a movable shaft 122, and the movable shaft 122 is in transmission connection with the second drive motor 116 through a belt 121. Further, the first rotary lifting assembly is arranged between the two sets of second rotary lifting assemblies. Compared with a single set of transmission systems, the double-set design can disperse the load, reduce the force on a single support column 119, and thus improve the overall stability of the system. The two sets of lead screws 117 are in transmission connection through a belt 121, enabling completely synchronous movement. This synchronous adjustment method ensures that the two support columns 119 always maintain the same posture during the lifting process, avoiding uneven changes in the posture of the spoiler body 2 caused by the independent movement of a single support column 119, thereby significantly enhancing the overall stability of the system.

[0040] A kind of adjustable rear spoiler body 2 provided in this embodiment has the following working process:

[0041] During use, when the driver needs to adjust the height of the rear spoiler body 2, start the first drive motor 106. The output shaft of the first drive motor 106 drives the worm 104 to rotate. When the worm 104 rotates, it drives the worm gear 110 to engage and move on the outer surface of the worm 104. When the worm gear 110 moves, the worm gear 110 drives the cylindrical shaft 108 to rotate. When the cylindrical shaft 108 rotates, it drives the inclined rod 111 to rotate through the transmission sleeve 109. When the inclined rod 111 rotates, it is restricted by the roller 113 inside the square frame 112, causing the rear side of the spoiler body 2 to move upward when the inclined rod 111 rotates. When the driver needs to adjust the height of the front spoiler body 2, start the second drive motor 116. The output shaft of the second drive motor 116 drives the movable shaft 122 to rotate through the belt 121. The rotating shaft and the movable shaft 122 drive the lead screws 117 to rotate. At this time, the rotation frequencies of the two lead screws 117 are synchronous. The rotation of the lead screws 117 drives the nut blocks 118 to move on the outer surfaces of the lead screws 117. The movement of the nut blocks 118 drives the support columns 119 to move synchronously. At this time, the movement of the support columns 119 drives the connecting blocks 120 to rise or fall, solving the problem that the spoiler body 2 cannot change the angle according to the dynamic conditions of the vehicle.
