Technical Field

[0001] This utility model relates to the field of automotive wheel arch technology, specifically to a wheel arch connection structure for automobiles. Background Technology

[0002] Wheel arches are part of the vehicle body panel, located above the wheels. They not only provide a decorative effect and enhance the vehicle's appearance, but also protect the outer side of the tires. When a wheel arch is scratched, it needs to be replaced or removed for repair through the wheel arch's connecting structure.

[0003] Existing automotive wheel arches are generally installed using bolts. However, because mudguards are installed at the tires, the mudguards must be removed before the wheel arches can be installed or removed directly. This makes wheel arch installation and removal time-consuming, labor-intensive, and inconvenient. Therefore, we propose a new wheel arch connection structure to solve the problems mentioned above.

[0016] 3. Beneficial effects:

[0017] Compared with the prior art, the wheel arch connection structure of this utility model, using the technical solution provided by this utility model, has the following specific details:

[0018] (1) When installing the wheel arch, the wheel arch is inserted into the wheel arch groove, and the wheel arch drives the mounting block into the positioning groove. The pressing plate retracts the stop bar into the stop bar groove. When the wheel arch abuts against the inner wall of the wheel arch groove, the stop bar at the stop bar groove completely penetrates the mounting groove. The stop bar is reset and moved out of the stop bar groove, so that the stop bar and the wheel arch abut against the inner and outer sides of the automotive sheet metal respectively, and the mounting block is fixed in the mounting groove, thereby completing the fixed installation of the wheel arch. When it is necessary to remove the wheel arch, the pressing plate drives the stop bar to retract into the stop bar groove through the transmission mechanism, so that the wheel arch drives the mounting block to move out of the mounting groove. Through the connection structure of the wheel arch, the wheel arch can be quickly and directly removed and installed, which effectively improves the efficiency of wheel arch removal and installation, so as to remove, repair or replace the wheel arch.

[0019] (2) When the wheel arch drives the mounting block to be inserted into the mounting groove, the inner wall of the mounting groove abuts against the end curved surface of the stop bar, causing the stop bar to be forced to move into the transmission groove. The stop bar drives the slide bar to move, and the slide bar drives the transmission frame to move through the slide bar groove. The transmission frame drives the guide rod and the pressing plate to move against the spring force. When the mounting block at the stop bar is completely through the mounting groove, the spring causes the stop bar to return to its original position and extend out of the stop bar groove. When the wheel arch needs to be removed, the pressing plate can drive the transmission frame to move into the transmission groove, causing the transmission frame to retract into the stop bar groove through the slide bar groove and the slide bar. Then, through the transmission mechanism, the pressing plate and the spring can drive the stop bar to move closer or further away from each other.

[0020] (3) When installing the wheel arch, the wheel arch drives the positioning rod to insert into the positioning groove. The spherical end of the positioning rod facilitates the insertion of the positioning rod into the positioning groove. At the same time, the guide structure formed by the positioning rod and the positioning groove can guide the installation of the wheel arch and thus position the installation of the wheel arch so that the wheel arch drives the mounting block to insert into the interior of the mounting groove.

[0030] Please see Figures 1 to 4 A wheel arch connection structure for an automobile includes an automobile sheet metal 1, with a wheel arch groove 2 provided on the outer side of the automobile sheet metal 1 and a wheel arch 3 provided on the inner side of the wheel arch groove 2.

[0031] The automotive sheet metal 1 has an installation groove 4 that is equidistantly inserted through the inner side of the wheel arch groove 2. The wheel arch 3 is fixedly connected to one side of the installation groove 4. The installation block 5 has a stop bar groove 8 symmetrically opened on both sides. The installation block 5 has a transmission groove 9 inside. The stop bar groove 8 has a stop bar 10 that passes through it. The stop bar 10 is located inside the transmission groove 9 and has a baffle 11 fixedly connected to one end.

[0032] The outer side of the wheel arch 3 corresponding to the transmission groove 9 is provided with a pressing plate groove 12. The transmission groove 9 and the pressing plate groove 12 are connected through the guide rod groove 13. The guide rod groove 13 is through which the guide rod 14 passes. One end of the guide rod 14 is fixedly connected to the pressing plate 15 inside the pressing plate groove 12. The pressing plate 15 drives the stop rod 10 to move closer or further away from each other through the transmission mechanism.

[0033] When installing the wheel arch 3, the wheel arch 3 is inserted into the wheel arch groove 2, causing the wheel arch 3 to drive the mounting block 5 into the positioning groove 6. The pressing plate 15 drives the stop rod 10 to move closer together through the transmission mechanism, causing the stop rod 10 to retract into the stop rod groove 8. When the wheel arch 3 abuts against the inner wall of the wheel arch groove 2, the stop rod 10 at the stop rod groove 8 completely penetrates the mounting groove 4. The stop rod 10 resets and moves out of the stop rod groove 8, so that the stop rod 10 and the wheel arch 3 abut against the inner and outer sides of the automotive sheet metal 1 respectively, fixing the mounting block 5 in the mounting groove 4, thus completing the fixed installation of the wheel arch 3. When it is necessary to remove the wheel arch 3, the pressing plate 15 drives the stop rod 10 to retract into the stop rod groove 8 through the transmission mechanism, so that the wheel arch 3 and the mounting block 5 can be moved out of the mounting groove 4. Through this connection structure of the wheel arch 3, the wheel arch 3 can be quickly and directly removed and installed, effectively improving the efficiency of the wheel arch 3 removal and installation, so as to remove, repair or replace the wheel arch 3.

[0034] Please see Figures 1 to 4 The inner sides of the wheel arch groove 2 are symmetrically connected to positioning grooves 6. The wheel arch 3 is fixedly connected to one side of the positioning groove 6. The end of the positioning rod 7 is spherical, and the outer diameter of the positioning rod 7 matches the inner diameter of the positioning groove 6. When installing the wheel arch 3, the wheel arch 3 drives the positioning rod 7 to be inserted into the positioning groove 6. The spherical end of the positioning rod 7 facilitates the insertion of the positioning rod 7 into the positioning groove 6. At the same time, the guide structure formed by the positioning rod 7 and the positioning groove 6 can guide the installation of the wheel arch 3 and thus position the installation of the wheel arch 3 so that the wheel arch 3 can drive the mounting block 5 to be inserted into the interior of the mounting groove 4.

[0035] Please see Figures 1 to 4 The vertical distance between the stop bar groove 8 and the wheel arch 3 matches the thickness of the automotive sheet metal 1 at the mounting groove 4. The stop bar 10 is a rectangular column, and the external dimensions of the stop bar 10 match the internal dimensions of the stop bar groove 8. The side of the stop bar 10 away from the baffle 11 is curved.

[0036] Please see Figures 1 to 4The transmission mechanism includes a spring 16. A spring 16 is fitted onto a guide rod 14 between the pressing plate 15 and the guide rod groove 13. A support rod 17 is fixedly connected to the side of the baffle 11 away from the stop rod 10. Slide rods 18 are symmetrically fixedly connected to both sides of the support rod 17. A transmission frame 19 is symmetrically fixedly connected to both sides of the guide rod 14 near the support rod 17. A slide rod groove 20 is provided on the transmission frame 19 corresponding to the position of the slide rod 18. The slide rod grooves 20 on both sides of the transmission frame 19 are arranged in a V-shape, and the inner width of the slide rod groove 20 matches the outer diameter of the slide rod 18. When the wheel arch 3 drives the mounting block 5 to insert into the mounting groove 4, the inner wall of the mounting groove 4 abuts against the end curved surface of the stop rod 10, causing the stop rod 10 to be subjected to force towards the transmission mechanism. The stop rod 10 moves within the groove 9, causing the slide rod 18 to move. The slide rod 18 then moves the transmission frame 19 through the slide rod groove 20, causing the transmission frame 19 to move the guide rod 14 and the pressing plate 15 against the spring force of the spring 16. When the mounting block 5 at the stop rod 10 completely penetrates the mounting groove 4, the spring 16 causes the stop rod 10 to return to its original position and extend out of the stop rod groove 8. When it is necessary to remove the wheel arch 3, the pressing plate 15 can drive the transmission frame 19 to move into the transmission groove 9, causing the transmission frame 19 to drive the stop rod 10 to retract into the stop rod groove 8 through the slide rod groove 20 and the slide rod 18. Furthermore, through the transmission mechanism, the pressing plate 15 and the spring 16 can drive the stop rod 10 to move closer or further apart.

[0037] Working principle: When using this car's wheel arch connection structure, such as Figures 1 to 4 As shown, firstly, when installing the wheel arch 3, the wheel arch 3 is inserted into the wheel arch groove 2, and the wheel arch 3 drives the mounting block 5 to insert into the positioning groove 6. The pressing plate 15 drives the stop rod 10 to move closer to each other through the transmission mechanism, so that the stop rod 10 retracts into the stop rod groove 8. When the wheel arch 3 abuts against the inner wall of the wheel arch groove 2, the stop rod 10 at the stop rod groove 8 completely penetrates the mounting groove 4. The stop rod 10 resets and moves out of the stop rod groove 8, so that the stop rod 10 and the wheel arch 3 abut against the inner and outer sides of the car sheet metal 1 respectively, fixing the mounting block 5 in the mounting groove 4, thereby completing the fixed installation of the wheel arch 3. When it is necessary to remove the wheel arch 3, the pressing plate 15 drives the stop rod 10 to retract into the stop rod groove 8 through the transmission mechanism, so that the wheel arch 3 drives the mounting block 5 to move out of the mounting groove 4. Through this connection structure of the wheel arch 3, the wheel arch 3 can be quickly and directly removed and installed, effectively improving the efficiency of the wheel arch 3 removal and installation, so as to remove, repair or replace the wheel arch 3.

[0038] When installing the wheel arch 3, the wheel arch 3 drives the positioning rod 7 to insert into the positioning groove 6. The spherical end of the positioning rod 7 facilitates insertion into the positioning groove 6. Simultaneously, the guide structure formed by the positioning rod 7 and the positioning groove 6 guides the installation of the wheel arch 3, thereby positioning it so that the wheel arch 3 drives the mounting block 5 to insert into the mounting groove 4. When the wheel arch 3 drives the mounting block 5 into the mounting groove 4, the inner wall of the mounting groove 4 abuts against the curved end of the stop rod 10, causing the stop rod 10 to move into the transmission groove 9 under force. The stop rod 10 then drives the sliding rod 18 to move. The transmission frame 19 is moved by the slide bar groove 20, which in turn moves the guide rod 14 and the pressing plate 15 against the elastic force of the spring 16. When the mounting block 5 at the stop bar 10 completely penetrates the mounting groove 4, the spring 16 causes the stop bar 10 to return to its original position and extend out of the stop bar groove 8. When the wheel arch 3 needs to be removed, the pressing plate 15 can move the transmission frame 19 into the transmission groove 9, so that the transmission frame 19 can drive the stop bar 10 to retract into the stop bar groove 8 through the slide bar groove 20 and the slide bar 18. Then, through the transmission mechanism, the pressing plate 15 and the spring 16 can move the stop bar 10 closer or further away from each other.
