Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of automobile parts, in particular to a front wheel cover frame structure and a reinforcing structure thereof. BACKGROUND

[0002] The front wheel cover is an indispensable part of the lower body of a white car, and plays a very important role in the overall structure of the white car. In addition to providing mounting support for the front suspension and mounting other accessories such as wire harness, it also has a great impact on the overall stiffness and modal of the white car and the crash performance. The existing front wheel cover of a car is usually an independent sheet metal, and in order to facilitate stamping, a material with low yield strength and thin thickness is usually selected, resulting in low strength of the front wheel cover itself. Moreover, the front wheel cover is used to fix the front shock absorber assembly, and during driving, the front wheel cover needs to withstand the impact force from the front shock absorber for a long time, which causes the front wheel cover to easily crack and poses a safety hazard to the car.

[0003] The existing front wheel cover is a whole part, and the part structure is complex, the drawing depth is very deep, which results in a complex die process of the part and a high scrap rate. At the same time, the blank size of the part is large, which results in a high cost of the part.

[0004] The above-mentioned problems in the prior art are solved by overlapping the front part of the rear section of the wheel cover on the outer surface of the rear part of the middle section and fixedly connecting them to form a composite connection section, so as to solve the problems of low strength and heavy weight, and to realize the connection with other parts and the support of the shock absorber.

[0005] The existing front wheel cover cannot effectively reduce the air resistance of the car during driving, and the protective plate on the front wheel cover and the connection between the front wheel cover and the car body are not very fixed. When the car encounters a collision, it cannot buffer the A-pillar, which can easily cause the A-pillar to break, thereby causing great safety hazards to the driver's cabin and the passenger cabin.

When the car encounters a collision, it cannot buffer the A-pillar, which can easily cause the A-pillar to break, thereby causing great safety hazards to the driver's cabin and the passenger cabin.

Detailed Implementation

[0028] like Figures 1-5 As shown, the present invention provides a front wheel arch frame structure, including an edge protection plate 1, a wheel arch body 2 on the outer wall of the edge protection plate 1, and the edge protection plate 1 and the wheel arch body 2 being fixedly connected. To facilitate the installation of the overall wheel arch and frame, the edge protection plate 1 is provided with side plate mounting holes 3. Extension plates 4 are provided on both sides of the wheel arch body 2, and the extension plates 4 are fixedly connected to the wheel arch body 2. To ensure a more convenient and rigid connection between the wheel arch body 2 and the vehicle body, the extension plates 4 are provided with a frame connection mechanism, which includes mounting components 5 and connecting parts 6. The moving part 6, clamping part 7, and mounting part 5 are fixedly connected to the linkage part 6. The linkage part 6 is fixedly connected to the clamping part 7. The mounting part 5 includes a mounting base 501, which is located on the extension plate 4. The mounting base 501 is provided with fasteners 502, which are fixedly connected to the mounting base 501. The mounting base 501 is fixedly connected to the extension plate 4 through the fasteners 502. A connecting plate 503 is provided in the middle of the mounting base 501, which is fixedly connected to the mounting base 501 and rotatably connected to the linkage part 6. In particular, the connecting plate 503 is the mounting mold of the linkage part 6. The fixing of the mounting base 501 and the extension plate 4 by the fasteners 502 ensures the fixation of the connecting plate 503, making the connecting plate 503 a stable power transmission hub, thereby making the entire front wheel arch more stable when fixedly connected.

[0029] The linkage component 6 includes two power clamping blocks 601. One end of each power clamping block 601 is fixedly connected, and the other end of each power clamping block 601 is provided with a clamping block rotation shaft 602. The clamping block rotation shaft 602 is fixedly connected to the two power clamping blocks 601 and rotatably connected to the connecting plate 503. Specifically, the fixed connection between the clamping block rotation shaft 602 and the power clamping blocks 601 allows the power clamping blocks 601 to rotate via the clamping block rotation shaft 602 without detaching from the connecting plate 503, thus achieving the purpose of rotation.

[0030] The connecting plate 503 is provided with two drive connectors 603, one end of which is fixedly connected. One end of one drive connector 603 is provided with a drive connecting shaft 604. The drive connector 603 and the drive connecting shaft 604 are fixedly connected, and the drive connecting shaft 604 is rotatably connected to the connecting plate 503.

Specifically, when the power clamping blocks 601 rotate via the clamping block rotation shaft 602, they drive the connecting member 605 to rotate. The drive connecting member 603 then rotates along with the connecting member 605 via the drive connecting shaft 604, thereby driving the connecting member 603 to change its original position.

[0032] The clamping component 7 includes a mounting shim 701, which is located in the drive connector 603 away from the drive connecting shaft 604. The mounting shim 701 is fixedly connected to clamping blocks 702 at both ends, and the clamping blocks 702 are fixedly connected to one of the drive connectors 603.

The bottom of the threaded rod 703 is fixedly connected to a cam 704, and the cam 704 is fixedly connected to a clamping rod 705. The extension plate 4 is provided with a through groove 706, and the other end of the clamping rod 705 passes through the through groove 706 and is fixedly connected to a reinforcing rib. The top of the reinforcing rib is slidably connected to a sliding groove, and the sliding groove is fixedly connected to the extension plate 4.

[0033] A front wheel arch frame reinforcement structure is provided, wherein a reinforcement mechanism is fixedly connected to the inner wall of the edge protection plate 1, and the edge protection plate 1 is fixedly connected to the wheel arch body 2 through the reinforcement mechanism; the reinforcement mechanism includes a mold component 8, a connecting component 9, and a reinforcement component 10, both of which are located inside the mold component 8. The connecting component 9 is connected to the reinforcement component 10. The mold component 8 includes a first cylinder 801, a gasket 802 is fixedly connected to the bottom of the first cylinder 801, a second cylinder 803 is provided inside the first cylinder 801, and the first cylinder 801 and the second cylinder 803 are fixedly connected. The second cylinder 803 is provided inside the connecting component 9.

[0034] The connecting component 9 includes a mounting post 901, a rotating nut 902 rotatably connected to the top of the mounting post 901, a reinforcing threaded rod 903 threadedly connected to the rotating nut 902, and a moving rod 904 rotatably connected to the bottom of the reinforcing threaded rod 903. A compression spring 907 is fixedly installed on the moving rod 904, and a limit rod 905 is fixedly connected to the bottom of the moving rod 904. The limit rod 905 is located on the connecting shaft 906.

[0035] The mounting post 901 is fitted inside the cylinder 803. The bottom end of the reinforcing threaded rod 903 passes through the mounting post 901 into the post. The side wall of the mounting post 901 is engaged with the compression spring 907. The limiting rod 905 is secured to the connecting shaft 906 through the limiting groove.

[0036] The reinforcing component 10 includes a connector 1001, a U-shaped connector 1002 fixedly connected to the top of the connector 1001, a pressure plate 1003 movably connected to the connector 1001, and a connecting rod 1004 provided at the bottom of the connector 1001. The connector 1001 is located at the middle of the top of the second cylinder 803. The pressure plate 1003 is fixedly connected to the top of the mounting column 901. A slot is provided in the middle of the connecting shaft 906. The connecting rod 1004 is vertically installed in the second cylinder 803 through the slot and is fixedly connected to the second cylinder 803. The connecting shaft 906 and the connecting rod 1004 are rotatably connected by a rotating rod.

[0037] The working principle of the front wheel arch frame structure and its reinforcement structure will be explained in detail below.

[0038] like Figures 1-5 As shown, after the wheel cover body 2 and the extension plate 4 are measured and positioned, the power clamping block 601 is rotated. When the power clamping block 601 rotates through the clamping block rotating shaft 602, it drives the connecting piece 605 to rotate. The driving connecting piece 603 follows the rotation of the connecting piece 605 through the driving connecting shaft 604, thereby driving the connecting piece 603 to change its original position. This drives the mounting pad 701 fixedly connected to one end of the driving connecting block 603 to change its height, causing the threaded rod 703 on the mounting pad 701 to rise or fall. As a result, the cam 704 moves. The cam 704 drives the clamping rod 705 to move. The clamping rod 705 drives the reinforcing rib 707 to move. After the two reinforcing ribs 707 slide to a certain position in the slide groove, they overlap and are thus fixedly connected to the extension plate 4.

[0039] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
