Description

轿 车 尾 部 阻 流 器 本发明涉及轿车尾部阻流器， 它能在轿车行驶时调节阻流板的阻流 作用， 以保持车轮附着力和车辆稳定性，  The present invention relates to a car rear spoiler. The present invention relates to a car rear spoiler, which can adjust the choke effect of a spoiler when the car is running to maintain wheel adhesion and vehicle stability.

众所周知， 轿车在高速行驶时， 特别是在轿车后部负荷小的情况下， 车身前倾， 后部上翘， 后轮附着力降低， 车辆稳定性、 安全性变差. 为 了克服上述缺点， 近年来在轿车尾箱盖上出现了尾部阻流器， 轿车尾部 阻流器是在阻流板两端设有支座， 支座紧固在尾箱盖上， 有的在阻流板 中部也设有固定的支座. 这种轿车尾部阻流器由于是固定的， 在车辆起 步和低、 中、 高速行驶的各个阶段、 各种状态和各种路况条件下， 都起 着同样的阻流作用， 不能够随车轮附着力和车辆稳定性的变化而调节阻 流作用， 所以固定式尾部阻流器降低了车辆的动力性和经济性，  As we all know, when the car is driving at high speed, especially when the load of the rear part of the car is small, the body leans forward, the rear part is upturned, the rear wheel adhesion is reduced, and the stability and safety of the vehicle are deteriorated. The rear spoiler appeared on the trunk lid of the car. The rear spoiler of the car is provided with supports at both ends of the spoiler. The supports are fastened to the trunk cover, and some are also provided in the middle of the spoiler. There is a fixed support. Because this car's rear spoiler is fixed, it plays the same choke function in all phases, states and road conditions of the vehicle at start and low, medium and high speed driving. , Can not adjust the choke effect with the change of wheel adhesion and vehicle stability, so the fixed rear choke reduces the vehicle's power and economy,

本发明的目的是， 提供一种能够随车轮附着力和车辆稳定性的变化 而调节阻流作用的轿车尾部阻流器. 这样， 既能够保证车辆在起步和低、 中速行驶时的动力性、 经济性， 又能够在车辆高速行驶时保持最佳车轮 附着力和车辆稳定性、 安全性.  The object of the present invention is to provide a rear spoiler of a sedan that can adjust the choking effect with the change of wheel adhesion and vehicle stability. In this way, the dynamic performance of the vehicle at the time of starting and low and medium speed driving can be ensured , Economical, and can maintain the best wheel adhesion and vehicle stability and safety when the vehicle is driving at high speed.

为达到上述目的， 本发明采用以下方案来实现： 在轿车尾箱盖上方 设有阻流板， 阻流板两端设有支座， 支座紧固在尾箱盖上， 其中， 阻流 板两端与支座相铰联， 阻流板下方中部设有油缸， 油缸的活塞杆与阻流 板相连接， 油缸的缸体与尾箱盖下方内側相连.  In order to achieve the above object, the present invention adopts the following solution to achieve: a spoiler plate is provided above the tailgate cover of the car, and two ends of the spoiler plate are provided with supports, and the supports are fastened to the tailgate cover, wherein the spoiler plate The two ends are hinged to the support, and an oil cylinder is arranged in the middle below the spoiler. The piston rod of the oil cylinder is connected to the spoiler. The cylinder body of the oil cylinder is connected to the inner side below the tail box cover.

本发明由于阻流板两端与支座相铰联， 阻流板下方设有油缸， 油缸 内的活塞往复运动， 经活塞杆带动阻流板上下浮动， 而使阻流板能够在 车辆行驶中的不同速度、 各种状态和各种路况条件下， 不断上下浮动， 不断调节阻流板的阻流作用， 而使车辆保持最佳的附着力， 提高了车辆 稳定性、 安全性及其动力性、 经济性.  Because the two ends of the spoiler are hinged to the support, an oil cylinder is arranged below the spoiler, and the piston in the oil cylinder reciprocates, and the spoiler is driven to float up and down by the piston rod, so that the spoiler can be driven by the vehicle Under different speeds, various states and various road conditions, it constantly floats up and down, and constantly adjusts the choke effect of the choke plate, so that the vehicle maintains the best adhesion, and improves the stability, safety and power of the vehicle , Economical.

下面结合附图示意表示的一个实施例来详细说明本发明. 其中， 图 1是轿车尾部主視图，  The present invention will be described in detail below with reference to an embodiment schematically shown in the drawings. Among them, FIG. 1 is a front view of a rear part of a car,

附图中， 图 1 ~ 3是轿车尾部的主视图、 左视图及俯视图， 示意表 示阻流板 2通过支座 3安装在尾箱盖 4的上方. In the drawings, FIGS. 1 to 3 are a front view, a left side view, and a top view of a rear part of a car, which are schematic diagrams. The choke plate 2 is installed above the tail box cover 4 through the support 3.

下面参阅图 4和 5 . 设在轿车尾箱盖 4上方的阻流板 2其两端经铰 联轴 6铰联在支座 3上， 可以使阻流板 2在支座 3上上下自由活动； 支座 3可以采用紧固螺栓 14紧固在尾箱盖 4的启闭合页的延长块 5上. 为减 少尾箱盖 4上方承受的压力， 可以在尾箱盖 4的启闭合页的延长块 5上 方设有调整螺母 13 , 下方设有紧固螺母 15 .  4 and 5. The spoiler 2 provided above the trunk lid 4 of the car is hinged on the support 3 via a hinge shaft 6 so that the spoiler 2 can move freely up and down on the support 3. The support 3 can be fastened to the extension block 5 of the opening and closing page of the tail box cover 4 by using fastening bolts 14. In order to reduce the pressure on the opening and closing page of the tail box cover 4, the opening and closing page of the tail box cover 4 can be reduced. The extension block 5 is provided with an adjusting nut 13 above and a fastening nut 15 below.

阻流板 2下方中部设有油缸 11， 油缸 11 可以设置在尾箱盖 4后方 内側， 油缸 11的活塞杆 10与阻流板 2相连接； 为使活塞杆 10能够灵活 地带动阻流板 2上下浮动， 可以在尾箱盖 4后方内側设油缸支架 12 , 油 缸 11下方经铰联轴 19铰联在油缸支架 12上； 活塞杆 10上方与阻流板 2 下方中部相铰联. 在图 4 所示的实施例中采用了球轴承， 其中， 在阻流 板 2下方中部设有球头座 7 , 活塞杆 10上方设有球头 8， 经球头盖 1将 活塞杆 10与阻流板 2铰接在一起.也可以采用支架与铰联轴将活塞杆 10 与阻流板 2相互铰联. 这样， 当油缸 11的上进出油口 16进油而下进出 油口 18回油时， 活塞 17下行， 从而带动阻流板 2下浮； 而当油缸 11的 上进出油口 16排油而下进出油口 18进油时， 活塞 17上行， 从而带动阻 流板 2上浮. 在活塞 17上下往复运动时， 阻流板 2也随之上下浮动， 从 而实现了对阻流板阻流作用的调节.  An oil cylinder 11 is provided in the middle of the lower part of the spoiler plate 2. The oil cylinder 11 may be disposed inside the rear of the tailgate 4; the piston rod 10 of the oil cylinder 11 is connected to the spoiler plate 2. In order to allow the piston rod 10 to drive the spoiler plate 2 flexibly Floating up and down, a cylinder bracket 12 can be installed inside the rear of the tailgate 4, and the cylinder 11 is hinged on the cylinder bracket 12 via a hinge shaft 19; the upper part of the piston rod 10 and the middle part of the spoiler 2 are hinged. In the embodiment shown, a ball bearing is used, wherein a ball head seat 7 is provided at the lower middle of the spoiler 2, a ball head 8 is provided above the piston rod 10, and the piston rod 10 and the spoiler are connected through the ball head cover 1. 2 is articulated together.
