[0002] As an important outer panel structure of an automobile body, the fender can cover the wheels and effectively prevent objects such as mud or gravel splashed by the wheels from flying onto the bottom of the carriage during vehicle driving. During the installation process of the fender, an installation bracket is usually used to position the installation position of the fender, but the existing installation bracket cannot accurately position the gap between the fender and the hood. Summary of the Invention

[0003] The technical problem to be solved by the present invention is to provide a positioning fixture for a front fender, which can ensure the positioning accuracy of the gaps between the front fender and the body side panel and between the front fender and the hood, and can achieve the synchronous positioning of the two front fenders.

[0004] The technical solution adopted by the present invention to solve its technical problem is to provide a positioning fixture for a front fender, including a positioning bracket. The positioning bracket is provided with a first positioning pin and a support positioning block and can be positioned in the engine compartment through the first positioning pin and the support positioning block. Floating positioning mechanisms are respectively arranged on both sides of the positioning bracket. The floating positioning mechanism includes a slide rail, a slider, a first connecting block, a second connecting block, a return spring, a limiting block, a hood stop block and a fender positioning block. The first connecting block is installed on the positioning bracket through the cooperation of the slider and the slide rail and can slide along the direction of both sides of the positioning bracket. Both ends of the stroke of the first connecting block are limited by the limiting block. The first connecting block is connected with the return spring and the sliding of the first connecting block is affected by the return spring. The second connecting block is connected with the first connecting block. The hood stop block and the fender positioning block are installed on the second connecting block. The horizontal distance between the vertical positioning surface of the hood stop block for the edge of the hood and the vertical positioning surface of the fender positioning block for the edge of the fender matches the standard gap between the hood and the front fender. Extension positioning arms are respectively arranged on both sides of the positioning bracket, and a second positioning pin for positioning the front end of the front fender is arranged on the extension positioning arm.

[0005] First positioning pins are respectively arranged at the positions corresponding to the shock absorber holes on both sides of the engine compartment at the bottom of the rear side of the positioning bracket.

[0006] Support positioning blocks are respectively arranged on both sides of the front and rear ends of the positioning bracket, and the support positioning blocks can cooperate with the vehicle skeleton to form a positioning support for the positioning bracket.

[0007] Two sets of floating positioning mechanisms are respectively installed on both sides of the positioning bracket.

[0008] The sliding rail is fixedly installed on the positioning bracket and its two ends face the two sides of the positioning bracket respectively. The slider is slidably installed on the sliding rail, and the first connecting block is installed on the slider.

[0009] Support blocks are respectively installed on the positioning bracket corresponding to the two ends of the sliding rail. The limiting block is installed on the support block corresponding to the first connecting block, and the return spring is arranged between the first connecting block and the support block at the inner side end of the sliding rail.

[0010] The second connecting block is T-shaped. The horizontal arm of the second connecting block is connected to the first connecting block, and the vertical arm extends out of the outer side of the positioning bracket. The hood stop block and the fender positioning block are installed on the vertical arm of the second connecting block corresponding to each other up and down.

[0011] The side of the hood stop block facing the positioning bracket is set as a stepped structure. The vertical surface of the stepped structure of the hood stop block is the positioning surface of the hood edge. The side of the fender positioning block facing away from the positioning bracket is set as a stepped structure. The vertical surface of the stepped structure of the fender positioning block is the positioning surface of the front fender edge.

[0012] The hood stop block and the fender positioning block are respectively installed on the second connecting block through adjustable gaskets.

[0013] The extension positioning arms are correspondingly arranged on both sides of the front end of the positioning bracket. The positioning end of the second positioning pin is in a stepped shape with a positioning surface and the second positioning pin is a telescopic adjustable structure.

[0014] Beneficial effects

[0015] First, in the present invention, the positioning bracket can be accurately positioned in the engine compartment of the vehicle. By extending the positioning arms to cooperate with the second positioning pins, the front end of the front fender can be positioned, ensuring the accuracy of the position where the front end of the front fender is installed on the body side panel.

[0016] Second, in the present invention, the gap between the front fender and the hood is positioned by the floating positioning mechanism. The horizontal distance between the vertical positioning surface of the hood edge by the hood stop block and the vertical positioning surface of the fender edge by the fender positioning block matches the standard gap between the hood and the front fender. By the cooperative positioning formed between the hood stop block and the hood edge, the fender positioning block is pushed to move in place. By installing the edge of the front fender to match the vertical positioning surface of the fender positioning block, the positioning accuracy of the gap between the fender and the hood can be ensured.

[0017] Third, the present invention can achieve the positioning of the front fenders on both sides of the vehicle at the same time, avoiding the separate positioning operation, which is beneficial to improving the convenience of the positioning and installation of the front fenders.
