Description

Technical Field

[0001] This invention belongs to the field of automotive technology, specifically a fender structure for a new energy vehicle. Background Technology

[0002] Car fenders are the outer body panels that cover the wheels. During driving, car fenders prevent sand and mud kicked up by the wheels from splashing onto the bottom of the vehicle. Fenders are classified as front fenders and rear fenders based on their installation location. Some modern cars have fenders designed to be integrated with the body, manufactured as a single piece. However, considering the relatively high risk of fender collisions, and the ease of replacement as a separate component, most car fenders are still installed independently on the vehicle body.

[0003] Currently, car fenders are bolted to the vehicle body mounting brackets, which are welded to the body and cannot be moved, thus making the fenders unadjustable. However, when there are slight errors in the size and assembly of the car fenders, the fenders cannot be installed accurately, affecting the overall matching and aesthetics of the vehicle, as well as its overall performance. Therefore, improvements are needed to address these issues. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a fender structure for a new energy vehicle, comprising a fender body, three connecting pillars, and three mounting blocks. The three connecting pillars are fixedly connected to the inner side of the fender body. Each of the three mounting blocks has an inverted convex groove on one side facing the connecting pillar. A vertical sliding plate and a horizontal sliding plate are slidably installed inside the inverted convex groove. A sliding groove is provided in the middle of the vertical sliding plate and the horizontal sliding plate. A slider is slidably installed inside the inverted convex groove. An insert is fixedly connected to the middle of one side of the slider. The insert passes through two sliding grooves on the vertical sliding plate and the horizontal sliding plate. A groove is provided on one side of the slider located inside the insert. A rotating ball is installed between the middle of the other side of the slider and the groove. The rotating ball rolls in contact with the inner wall of the inverted convex groove. A fixing component is provided inside the groove. The three connecting pillars are movably inserted into the three inserts respectively. The ends of the connecting pillars located inside the inserts extend into the grooves and are movably connected to the fixing components. A reinforcing component is provided inside the inserts. The reinforcing component is movably connected to the middle of the connecting pillar.

[0005] Preferably, each of the three fixing components includes four shrinkage adjustment grooves that are equidistantly arranged in a ring inside the groove. Each shrinkage adjustment groove has a limit block movably inserted into its end. Each shrinkage adjustment groove has a threaded pin rotatably connected inside. One end of the threaded pin is threadedly connected to a square threaded tube. One end of the square threaded tube is fixedly connected to one end of the limit block with a spring.

[0006] Preferably, each of the three connecting columns is fixedly connected to a conical extrusion platform at its end. One side of each of the three connecting columns is provided with an insertion ring groove, and the other end of the limiting plug is provided with a first extrusion slope that matches the conical extrusion platform. The other end of the limiting plug is movably inserted into the inside of the insertion ring groove, so that the connecting column can be stably inserted into the inside of the insertion tube and the groove.

[0007] Preferably, the ends of the conical extrusion table are provided with inner arc grooves, and a first clamping rubber block is fixedly connected inside the inner arc groove. The first clamping rubber block is in contact with the rotating ball. The surface inside the inverted convex groove that contacts the rotating ball is a rough surface, which can effectively fix the slider, the vertical slide plate, and the horizontal slide plate.

[0008] Preferably, each of the three connecting posts has a plug that matches the inside of the insertion tube fixedly installed on the other side. One side of the plug has a compression bevel surface, and the middle of each of the three connecting posts has a locking groove.

[0009] Preferably, each of the reinforcing components includes four metal elastic strips that are fixedly connected at equal intervals in a ring inside the insertion tube. One end of each metal elastic strip is fixedly connected to a pressure block. One side of each pressure block is provided with a pressure inclined surface that matches the extrusion inclined ring surface. One side of each metal elastic strip is fixedly connected to a second clamping rubber block. The second clamping rubber block is movably engaged inside the clamping ring groove, thereby reinforcing the inserted connecting post and ensuring the firmness of the connection.

[0010] Preferably, each slider has a groove in the middle, a rotating ring is rotatably installed inside the groove, a gear ring is fixedly connected to the top of the rotating ring, the other end of the threaded pin extends into the groove and is fixedly connected to a first gear, the first gear meshes with the gear ring, and a turbine ring is fixedly connected to the circumference of the rotating ring.

[0011] Preferably, the inner cavity of the ring groove is rotatably connected to a first worm gear that meshes with the turbine ring, and a second gear is fixedly connected to one side of the first worm gear. The inner cavity of the ring groove is provided with an installation groove, and the inner cavity of the installation groove is rotatably connected to a third gear that meshes with the second gear. A turbine is fixedly connected to one side of the third gear, and the inner cavity of the installation groove is rotatably connected to a second worm gear that meshes with the turbine. One end of the second worm gear extends to the surface of the slider and is fixedly connected to a rotating nut, thereby enabling effective disassembly of the fender body.

[0012] Preferably, the bottom of each of the three mounting blocks is provided with a large opening aligned with the rotating nut. A sealing plate is installed inside the large opening. Both ends of the large opening are provided with a latch. Both ends of the sealing plate are provided with a toggle groove. An elastic lever is connected inside the toggle groove. One side of the elastic lever is fixedly connected with a locking block that is movably engaged inside the latch, thereby enabling the rotating nut to be rotated effectively.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] In operation, the fender structure of this new energy vehicle is equipped with an effective installation and adjustment mechanism by incorporating a fender body, connecting column, mounting block, inverted convex groove, vertical sliding plate, horizontal sliding plate, sliding groove, slider, insertion tube, groove, rotating ball, fixing component, and reinforcing part. This installation and adjustment mechanism allows for fine-tuning of the position of the installed fender, ensuring accurate installation even with minor dimensional and assembly errors, thus guaranteeing the vehicle's matching and aesthetics, as well as its overall performance. Furthermore, this installation and adjustment mechanism facilitates convenient installation and removal of the fender, making the process more convenient. The structure is simple in design, easy to use and operate, and provides stable and reliable installation and fixing, meeting the performance requirements for automotive fender installation.

[0015] When fine-tuning the position of the installed fender body is required, the three connecting posts on the fender body are inserted into the three insert tubes respectively. Then, by moving the fender body, the three connecting posts and the three insert tubes are moved. The movement of the insert tubes causes the slider to move through the rotating ball bearings. At the same time, the movement of the insert tubes can effectively move the vertical and horizontal sliding plates through the sliding grooves on the vertical and horizontal sliding plates, so that the insert tubes and the slider can be moved and adjusted to any position. When the position of the fender body is adjusted and can be accurately installed, press the fender body, so that the ends of the three connecting posts are inserted into the grooves. The connecting posts cause the conical extrusion table and the first clamping rubber block to move towards the rotating ball bearings. The first clamping rubber block squeezes the rotating ball bearings, and the uneven rough surface inside the inverted groove prevents the rotating ball bearings from rolling. The immobility of the rotating ball bearings keeps the slider, insert tubes, vertical sliding plate and horizontal sliding plate effectively stable.

[0016] When the connecting post is inserted into the tube and the groove, it will drive the conical extrusion platform to be inserted together. When the conical extrusion platform is inserted into the groove, it will compress the four limiting blocks. The first extrusion slope at the end of the limiting block will cause the first pressure to move into the shrinkage adjustment groove and compress the spring. As the connecting post and the conical extrusion platform are continuously inserted, when the end of the limiting block is aligned with the insertion ring groove, the elastic restoring force of the spring will cause the end of the limiting block to be inserted into the insertion ring groove, so that the connecting post can be stably inserted into the tube and the groove.

[0017] When fine-tuning the position of the installed fender body is required, the three connecting posts on the fender body are inserted into the three insert tubes respectively. Then, by moving the fender body, the three connecting posts and the three insert tubes are moved. The movement of the insert tubes causes the slider to move through the rotating ball bearings. At the same time, the movement of the insert tubes can effectively move the vertical and horizontal sliding plates through the sliding grooves on the vertical and horizontal sliding plates, so that the insert tubes and the slider can be moved and adjusted to any position. When the position of the fender body is adjusted and can be accurately installed, press the fender body, so that the ends of the three connecting posts are inserted into the grooves. The connecting posts cause the conical extrusion table and the first clamping rubber block to move towards the rotating ball bearings. The first clamping rubber block squeezes the rotating ball bearings, and the uneven rough surface inside the inverted groove prevents the rotating ball bearings from rolling. The immobility of the rotating ball bearings keeps the slider, insert tubes, vertical sliding plate and horizontal sliding plate effectively stable.

[0018] When the connecting post is inserted into the cannula, it will drive the insert block to be inserted into the cannula. As the insert block continues to be inserted into the cannula, the contact between the inclined ring surface and the pressure inclined surface will cause the pressure block to drive the metal elastic strip to bend. This will cause the metal elastic strip to drive the second clamping rubber block to be engaged in the clamping ring groove. This will allow the second clamping rubber block to firmly clamp the connecting post, ensuring the stability and firmness of the connecting post insertion without loosening.

[0029] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0030] Example 1, by Figures 1 to 7The present invention includes a fender body 1, three connecting posts 2, and three mounting blocks 3. The mounting blocks 3 are connected to a mounting bracket by bolts or welding. The three connecting posts 2 are fixedly connected to the inner side of the fender body 1. Each of the three mounting blocks 3 has an inverted convex groove 4 on the side facing the connecting posts 2. A vertical sliding plate 5 and a horizontal sliding plate 6 are slidably installed inside the inverted convex groove 4. A sliding groove 7 is opened in the middle of the vertical sliding plate 5 and the horizontal sliding plate 6. A slider 8 is slidably installed inside the inverted convex groove 4. An insertion tube 9 is fixedly connected to the middle of one side of the slider 8. The insertion tube 9 passes through the two sliding grooves 7 on the vertical sliding plate 5 and the horizontal sliding plate 6. A groove 10 is opened on the side of the slider 8 inside the insertion tube 9. A rotating ball 11 is installed between the middle of the other side of the slider 8 and the groove 10. The rotating ball 11 rolls in contact with the inner wall of the inverted convex groove 4. The interior of the groove 10 is equipped with fixing components. Three connecting posts 2 are movably inserted into the interior of three insert tubes 9. The end of the connecting post 2 located inside the insert tube 9 extends into the interior of the groove 10 and is movably connected to the fixing components. The interior of the insert tube 9 is equipped with reinforcing components, which are movably connected to the middle of the connecting post 2. Both ends of the vertical slide plate 5 and the horizontal slide plate 6 are provided with slots 46. Rollers 47 that contact the inner side wall of the inverted convex groove 4 are installed inside the slots 46, so that the vertical slide plate 5 and the horizontal slide plate 6 can move effectively. Three rubber blocks 48 are fixedly connected to the inner side of the fender body 1 located at the three connecting posts 2. The rubber blocks 48 contact one side of the mounting block 3 and seal the inverted convex groove 4, so as to effectively prevent dust and impurities from entering the interior of the inverted convex groove 4 and affecting the effective adjustment of the structure.

[0031] The fender structure of this new energy vehicle features an effective installation and adjustment mechanism. This mechanism allows for fine-tuning of the fender's position, ensuring accurate installation even with minor dimensional or assembly errors. This guarantees the vehicle's overall fit and aesthetics, as well as its comprehensive performance. Furthermore, the mechanism facilitates easy installation and removal of the fender, making the process more convenient. Its simple design, ease of use and operation, and stable and reliable installation and fixation meet the performance requirements for automotive fender installation.

[0032] In Embodiment 2, based on Embodiment 1, each of the three fixing components includes four shrinkage adjustment grooves 12 circumferentially and equidistantly formed inside the groove 10. Each end of the shrinkage adjustment groove 12 is movably inserted with a limiting block 13. Each shrinkage adjustment groove 12 is rotatably connected with a threaded pin 14. One end of the threaded pin 14 is threadedly connected to a square threaded tube 15. One end of the square threaded tube 15 is fixedly connected to one end of the limiting block 13 with a spring 16. Each end of the three connecting pillars 2 is fixedly connected with a conical extrusion table 17. One side of each of the three connecting pillars 2 is provided with an insertion ring groove 18. The other end of the limiting block 13 is provided with a first extrusion slope that matches the conical extrusion table 17. The other end of the limiting block 13 is movably inserted into the insertion ring groove 18, so that the connecting pillar 2 can be stably inserted into the insertion tube 9 and the groove 10.

[0033] When the connecting post 2 is inserted into the insertion tube 9 and the groove 10, it will drive the conical extrusion platform 17 to be inserted together. When the conical extrusion platform 17 is inserted into the groove 10, it will compress the four limiting blocks 13. The first extrusion slope of the end of the limiting block 13 by the conical extrusion platform 17 will cause the first pressure to move into the shrinkage adjustment groove 12 and compress the spring 16. As the connecting post 2 and the conical extrusion platform 17 are continuously inserted, when the end of the limiting block 13 is aligned with the insertion ring groove 18, the elastic restoring force of the spring 16 will cause the end of the limiting block 13 to be inserted into the insertion ring groove 18, so that the connecting post 2 can be stably inserted into the insertion tube 9 and the groove 10, thereby ensuring the stability of the fender body 1 installation.

[0034] The ends of the conical extrusion table 17 are provided with inner arc grooves 19. The inner arc groove 19 is fixedly connected with a first clamping rubber block 20. The first clamping rubber block 20 is in contact with the rotating ball 11. The surface of the inverted convex groove 4 that contacts the rotating ball 11 is a rough surface, which can effectively fix the slider 8, the vertical slide plate 5 and the horizontal slide plate 6.

[0035] When fine-tuning of the position of the installed fender body 1 is required, the three connecting posts 2 on the fender body 1 are inserted into the three insertion tubes 9 respectively. Then, by moving the fender body 1, the three connecting posts 2 and the three insertion tubes 9 are moved. The movement of the insertion tubes 9 causes the slider 8 to move by rotating the ball bearing 11. At the same time, the movement of the insertion tubes 9 can effectively move the vertical slide plate 5 and the horizontal slide plate 6 through the sliding grooves 7 on the vertical slide plate 5 and the horizontal slide plate 6, thereby allowing the insertion tubes 9 and the slider 8 to be moved and adjusted to any position. When the position of the fender body 1 is adjusted... When the section is completed and can be accurately installed, press the fender body 1, so that the fender body 1 drives the ends of the three connecting posts 2 to be inserted into the groove 10. The connecting posts 2 drive the conical extrusion table 17 and the first clamping rubber block 20 to move toward the rotating ball 11. The first clamping rubber block 20 squeezes the rotating ball 11 and the rough surface inside the inverted groove 4 prevents the rotating ball 11 from rolling. The immobility of the rotating ball 11 keeps the slider 8, the insertion tube 9, the vertical slide plate 5 and the horizontal slide plate 6 in a stable position, thus ensuring the stability of the fender body 1 installation.

[0036] In Example 3, based on Example 2, insert blocks 21 matching the inside of the insertion tube 9 are fixedly installed on the other side of each of the three connecting posts 2. One side of the insert block 21 is provided with a compression inclined surface 22, and the middle of each of the three connecting posts 2 is provided with a clamping groove 23. The reinforcing components include four metal elastic strips 24 that are fixedly connected to the inside of the insertion tube 9 at equal intervals in a ring. One end of each metal elastic strip 24 is fixedly connected with a pressure block 25. One side of each pressure block 25 is provided with a pressure inclined surface 27 matching the compression inclined surface 22, and one side of each metal elastic strip 24 is fixedly connected with a second clamping rubber block 26. The second clamping rubber block 26 is movably clamped inside the clamping groove 23, thereby reinforcing the inserted connecting post 2 and ensuring the firmness of the connection.

[0037] When the connecting post 2 is inserted into the tube 9, the connecting post 2 will drive the insert block 21 to be inserted into the tube 9. As the insert block 21 continues to be inserted into the tube 9, the contact between the inclined ring surface 22 and the pressure inclined surface 27 will cause the pressure block 25 to drive the metal elastic strip 24 to bend. This will cause the metal elastic strip 24 to drive the second clamping rubber block 26 to be inserted into the clamping ring groove 23. This will allow the second clamping rubber block 26 to firmly clamp the connecting post 2, ensuring that the insertion of the connecting post 2 is stable and firm and will not loosen.

[0038] In Example 4, based on Example 2, a groove 28 is provided in the middle of each slider 8. A rotating ring 29 is rotatably mounted inside the groove 28. A gear ring 30 is fixedly connected to the top of the rotating ring 29. The other end of each threaded pin 14 extends into the groove 28 and is fixedly connected to a first gear 31. The first gear 31 meshes with the gear ring 30. A turbine ring 32 is fixedly connected to the circumference of each rotating ring 29. A first worm 33 meshes with the turbine ring 32 inside the groove 28. A second gear 34 is fixedly connected to one side of the first worm 33. A mounting groove 35 is provided inside the groove 28. A third gear 36 meshes with the second gear 34 inside the mounting groove 35. A third gear 36 is rotatably connected to one side of the third gear 36. A turbine 37 is fixedly connected, and a second worm 38 that meshes with the turbine 37 is rotatably connected inside the mounting slot 35. One end of the second worm 38 extends to the surface of the slider 8 and is fixedly connected to a rotating nut 39, thereby enabling effective disassembly of the fender body 1. The bottom of each of the three mounting blocks 3 has a large opening 40 aligned with the rotating nut 39. A sealing plate 41 is installed inside the large opening 40. Both ends of the large opening 40 have a bayonet 42. Both ends of the sealing plate 41 have a toggle groove 43. An elastic paddle 44 is connected inside the toggle groove 43. One side of the elastic paddle 44 is fixedly connected to a locking block 45 that is movably engaged inside the bayonet 42, thereby enabling effective rotation of the rotating nut 39.

[0039] When it is necessary to disassemble the fender body 1, firstly, the retaining block 45 is moved out of the retaining slot 42 by using the elastic lever 44. Then, the sealing plate 41 is removed from the large opening 40. Next, the rotating nut 39 is rotated through the large opening 40 using a screwdriver. The rotation of the rotating nut 39 will drive the second worm 38 to rotate. The rotation of the second worm 38 will drive the turbine 37 to rotate, which in turn will drive the third gear 36 to rotate the second gear 34. The rotation of the second gear 34 will drive the first worm 33 to rotate, which will drive the turbine ring 32 to rotate the rotating ring 29. The rotation of the rotating ring 29 will drive the gear ring 30 to rotate, which in turn will drive the four first gears 31 to rotate. The rotation of the first gears 31 will drive the threaded pin 14 to rotate, which will cause the square threaded tube 15 to move. The movement of the square threaded tube 15 will pull the spring 16 and the limiting plug 13 to move, thereby causing the end of the limiting plug 13 to be withdrawn from the inside of the insertion ring groove 18. Then, the fender body 1 will be pulled, causing the fender body 1 to drive the connecting column 2, the conical extrusion table 17 and the first clamping rubber block 20 to be withdrawn from the inside of the insertion tube 9 and the groove 10, thus realizing the disassembly of the fender body 1.
