Description

Technical Field

[0001] This invention belongs to the field of new energy vehicle parts technology, specifically relating to a quick-installation fender for new energy vehicles. Background Technology

[0002] New energy vehicles refer to automobiles that use new power systems and are driven entirely or primarily by new energy sources. They are fundamentally different from traditional gasoline-powered vehicles, with the core difference being a fundamental transformation in their energy supply and power systems. The fender (also known as the wheel arch) is an important component of a new energy vehicle's body, installed above the wheels. Its main functions are to cover the wheels, prevent mud, sand, and gravel kicked up by the wheels from splashing out, and also to provide some aerodynamic guidance and decorative elements.

[0003] Existing new energy vehicle fenders are fastened to the vehicle frame with multiple screws. During assembly or disassembly, multiple screws need to be tightened repeatedly in sequence, which is a very cumbersome operation. Summary of the Invention

[0004] This invention provides a quick-install fender for new energy vehicles, which aims to solve the problem that existing fenders for new energy vehicles are fastened to the vehicle frame with multiple screws, requiring repeated sequential tightening of multiple screws during assembly or disassembly, which is very cumbersome.

[0005] This invention provides a quick-installation fender for new energy vehicles, comprising:

[0006] The fender body and the frame body are connected by an assembly module. The assembly module includes an assembly strip A installed on the frame body and an assembly strip B installed on the fender body. Rectangular openings are reserved on the opposite side of assembly strip A and assembly strip B.

[0007] The connecting unit includes assembly block A and assembly block B. Assembly block A is engaged in the rectangular opening on the side of assembly strip A, and assembly block B is engaged in the rectangular opening on the side of assembly strip B. Assembly block A and assembly block B are arranged facing each other to achieve the purpose of connecting assembly strip A and assembly strip B. An assembly opening is reserved on the outward side of assembly block A, and the connecting part A is installed in the assembly opening.

[0008] Connecting part A includes a rotating strip 1. One side of the rotating strip 1 is screwed to the vertical wall of the assembly port via a pin. The other side of the rotating strip 1 is fixed to an arched strip. The outward side of the assembly block B has an arched opening that matches the arched strip. The outward side of the assembly block A is fixed to a snap-fit ​​block. The outward side of the assembly block B has a fitting interface that matches the snap-fit ​​block. Both ends of the assembly block A and assembly block B have reserved movable openings. Both sides of the outward side of the assembly block A and assembly block B have reserved movable openings. Connecting part B is installed in the movable opening. Connecting part B includes a clamping post that is horizontally movable in the movable opening. The inward side of the clamping post is screwed to a rotating strip 2. The side of the rotating strip 2 that is farther from the clamping post is screwed to a snap-fit ​​post that is vertically movable inside the movable opening. An outer ring is fixed to the outer peripheral wall of the clamping post. A spring-loaded part B that is connected to the side wall of the outer ring is clamped to the outer peripheral wall of the clamping post.

[0009] Furthermore, the snap-fit ​​block is funnel-shaped, and the radius of the snap-fit ​​block gradually decreases from the side closest to assembly block A to the side furthest from assembly block A.

[0010] Furthermore, a spring-loaded component A is installed inside the rotating bar 1, which is clamped to the outside of the pin. A linkage table is fixedly connected to the side wall of the rotating bar 1. The linkage table is fan-shaped, and several teeth are reserved on the outer peripheral wall of the linkage table. A linkage bar is movably installed in the assembly mouth. A linkage plate is fixedly connected to the side of the linkage bar near the linkage table. Several teeth are reserved on one side of the linkage plate, and it is connected to the linkage table through the teeth.

[0011] Furthermore, a threaded opening is provided on the side wall of assembly strip A, and a lead screw is connected to the threaded opening. The edge of the lead screw is positioned opposite the edge of the linkage strip.

[0012] Furthermore, both assembly strip A and assembly strip B have pre-reserved snap-fit ​​interfaces that connect to the rectangular opening, and skewed walls are installed on the outside of the snap-fit ​​posts.

[0013] The beneficial effects of this invention are as follows:

[0014] This invention, through the installation of assembly strip A, assembly strip B, assembly block A, assembly block B, connecting part B and connecting part A, has a rectangular opening pre-reserved at the connection of assembly strip A and assembly strip B. Assembly block A and assembly block B are both snapped into the rectangular opening. After the accessories on connecting part B and connecting part A are assembled and tightened, they are all hidden in assembly block A, assembly block B or assembly strip A and assembly strip B. Furthermore, the threaded joints are assembled internally, with the threaded joints pre-reserved on the side wall of the edge of assembly strip A. After the screw is tightened, it is completely placed in the threaded joint and does not protrude from assembly strip A, ensuring the overall aesthetics.

[0015] The snap-fit ​​block on assembly block A is funnel-shaped and matches the insert on assembly block B. During assembly, it can achieve self-correction through the tilted wall, reducing the difficulty of assembly. In addition, the snap-fit ​​post and linkage bar in the initial form are all stored in the assembly block. There are no protruding parts on the outside of assembly blocks A and B, which can be successfully snapped into the rectangular opening. There is no obstruction during assembly. When assembling the fender body and the frame body, you only need to move the fender body to make the clamping post move under pressure, and then tighten the screw to achieve a tight connection. It is very simple to use.

[0016] Through the coordination of the connecting part B during assembly, during the assembly of assembly strip A and assembly strip B, after the clamping column is compressed, it is automatically engaged with the locking interface on the fender body by the traction locking column of the rotating strip two. Without the need to add other locking parts, it can achieve a stable connection between assembly block A, assembly block B and the corresponding fender body and the frame body, optimize the assembly process and make assembly faster.

[0017] First, assembly blocks A and B are corrected via funnel-shaped snap-fit ​​blocks and interlocking interfaces. Then, assembly blocks A, B, and the fender body are connected to the frame body via snap-fit ​​posts and snap-fit ​​interfaces. Finally, snap-fit ​​is performed via arched strips and arched openings to secure assembly blocks A, B, strip A, and strip B to each other. The arched strips and arched openings utilize an arched, tightly fitting structure with a sufficiently large contact area to evenly distribute external forces and ensure a reliable connection.

[0018] Other features and advantages of the invention will be set forth in the following description, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of the invention may be realized and obtained by means of the structures particularly pointed out in the description and the drawings. Attached Figure Description

[0031] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Reference Figures 1-10 This invention provides a quick-installation fender for new energy vehicles, comprising:

[0033] The fender body 1 and the frame body 2 are connected by an assembly module. The assembly module includes an assembly strip A3 installed on the frame body 2 and an assembly strip B4 installed on the fender body 1. A rectangular opening 31 is reserved on the opposite side of the assembly strip A3 and the assembly strip B4.

[0034] The connecting unit 5 includes assembly block A51 and assembly block B52. Assembly block A51 is engaged in the rectangular opening 31 on the side of assembly strip A3, and assembly block B52 is engaged in the rectangular opening 31 on the side of assembly strip B4. Assembly block A51 and assembly block B52 are arranged facing each other to achieve the purpose of connecting assembly strip A3 and assembly strip B4. Assembly opening 511 is reserved on the outward side of assembly block A51, and connecting part A53 is installed in assembly opening 511.

[0035] Among them, the connecting part A53 includes a rotating bar 531. One side of the rotating bar 531 is connected to the vertical wall of the assembly opening 511 by a pin. The other side of the rotating bar 531 is fixed to an arched bar 532. The outward side of the assembly block B52 has an arched opening 521 that is adapted to the arched bar 532.

[0036] The outer side of assembly block A51 is fixed to the snap-fit ​​block 512. The outer side of assembly block B52 has a reserved insertion interface 522 that is compatible with snap-fit ​​block 512. Both ends of assembly block A51 and assembly block B52 have reserved change openings 513. Both sides of the outer side of assembly block A51 and assembly block B52 have reserved change openings 513. The connecting part B54 is installed in the change opening 513.

[0037] The snap-fit ​​block 512 is funnel-shaped, and the radius of the snap-fit ​​block 512 gradually decreases from the side closest to the assembly block A51 to the side furthest from the assembly block A51.

[0038] Inside the rotating bar 531, a spring-loaded component A533 is installed, which is clamped to the outside of the pin. A linkage table 534 is fixedly connected to the side wall of the rotating bar 531. The linkage table 534 is fan-shaped, and several teeth are reserved on the outer peripheral wall of the linkage table 534. A linkage bar 535 is movably installed in the assembly port 511. A linkage plate 536 is fixedly connected to the side of the linkage bar 535 near the linkage table 534. Several teeth are reserved on one side of the linkage plate 536, and it is engaged with the linkage table 534 through the teeth.

[0039] The assembly strip A3 has a threaded opening 32 on its side wall. The threaded opening 32 has a T-shaped cross-section. The threaded opening 32 is connected to the lead screw 537. The edge of the lead screw 537 is directly opposite the edge of the linkage strip 535. The axial span of the threaded opening 32 is greater than the axial span of the lead screw 537.

[0040] The connecting part B54 includes a clamping post 541 that is laterally movable in the variable opening 513. The inward side of the clamping post 541 is screwed to the rotating bar 542. The side of the rotating bar 542 that is farther away from the clamping post 541 is screwed to the locking post 543 that is vertically movable inside the variable opening 513.

[0041] An outer ring 544 is fixed to the outer peripheral wall of the clamping column 541, and a spring-loaded component B545 connected to the side wall of the outer ring 544 is clamped to the outer peripheral wall of the clamping column 541.

[0042] Both assembly strips A3 and B4 have pre-reserved card interfaces 33 that connect to the rectangular opening 31, and the outside of the card connector 543 is fitted with a skewed wall.

[0043] The core of the assembly module includes assembly strip A3, assembly strip B4, and connecting unit 5. Assembly strip A3 and assembly strip B4 are two metal strips. Rectangular openings 31 are pre-drilled on the side walls of assembly strips A3 and B4. These rectangular openings 31 fit into the connecting unit 5 and are used to accommodate and assemble the accessories on the connecting unit 5. The rectangular openings 31 are positioned on the side walls of the assembly strips, specifically the surfaces where assembly strips A3 and B4 contact each other when they are joined. This allows for concealed assembly of the connecting part A53, which is then hidden inside the assembly block after assembly.

[0044] Connecting unit 5 is a key component for connecting the two assembly strips, comprising assembly block A51, assembly block B52, and connecting parts A53 and B54 installed inside the assembly blocks. Assembly block A51 engages with a rectangular opening 31 on the side wall of assembly strip A3, and assembly block B52 engages with a rectangular opening 31 on the side wall of assembly strip B4. Assembly blocks A51 and B52 are positioned opposite each other, meaning that when assembly strip A3 and assembly strip B4 are connected, assembly blocks A51 and B52 can cooperate to assemble assembly strip A3 and assembly strip B4. Assembly block A51 has a pre-reserved assembly opening 511 for receiving the components of connecting part A53. Both sides of assembly blocks A51 and B52 have pre-reserved movable openings 513 for receiving the components of connecting part B54.

[0045] In the initial state, within the connecting portion B54 inside the variable opening 513, the clamping column 541, under the deformation force of the spring-loaded component B545, extends outward from the assembly block A51. The spring-loaded component B545, in its self-extending state, exerts outward pressure on the outer ring 544, thereby pulling the clamping column 541 to maintain its outward extension. The inward side of the clamping column 541 is screwed onto the rotating bar 542. When the clamping column 541 extends outward, the inward side pulls the rotating bar 542, causing it to rotate. The side of the rotating bar 542 furthest from the clamping column 541 pulls the locking column 543 upward. At this moment, the locking column 543 is completely retracted into the variable opening 513, not extending beyond the assembly block A51 or assembly block B52, to prevent obstruction of the inner wall of the rectangular opening 31 during assembly of the assembly blocks A51 and B52.

[0046] Inside the connecting part A53, the rotating bar 531 is tilted to the right under the deformation force of the spring-loaded component A533. The spring-loaded component A533 is clamped to the outer circumference of the pin at the lower end of the rotating bar 531, creating a positive torsional action on the rotating bar 531. The inner wall of the assembly opening 511 contacts the side wall of the rotating bar 531, preventing the rotating bar 531 from continuing to rotate in the forward direction. It remains at the beginning of its rotation trajectory, only allowing it to rotate in the opposite direction when subjected to force later. When the rotating bar 531 is tilted to the right, the linkage platform 534 fixed to the outside is also in the corresponding position. At this time, the arched bar 532 is retracted into the assembly opening 511 and does not protrude from the assembly block A51 to prevent obstruction during the assembly of assembly block A51 and assembly block B52. The linkage plate 536, which engages with the linkage table 534, is constrained by the linkage table 534. The traction linkage bar 535 is located at the outermost side of its movement trajectory. At this moment, the bottom of the linkage bar 535 is inside the assembly block A51 to prevent the assembly block A51 from obstructing the inner wall of the rectangular opening 31 during assembly.

[0047] At this moment, the rectangular opening 31, card interface 33, and threaded opening 32 on assembly strip A3 and assembly strip B4 have been completed and are compatible with the corresponding accessories. Assembly block A51 and assembly block B52 have not been assembled into the rectangular opening 31.

[0048] Assembly of Assembly Blocks A51 and B52: First, assemble Assembly Blocks A51 and B52. Align Assembly Block A51 with the rectangular opening 31 on the side wall of Assembly Strip A3, and align Assembly Block B52 with the rectangular opening 31 on the side wall of Assembly Strip B4. Snap Assembly Blocks A51 and B52 into their respective rectangular openings 31. Therefore, the locking pin 543 is housed within the variable opening 513, and the linkage strip 535 is housed within the assembly opening 511. Any parts not protruding from the outside of Assembly Blocks A51 and B52 can be successfully snapped into the rectangular openings 31. After Assembly Blocks A51 and B52 are snapped into the rectangular openings 31, their outward-facing walls are flush with the side walls of Assembly Strips A3 and B4, ensuring tight contact between the fender body 1 and the frame body 2 during subsequent assembly.

[0049] Assembly of Assembly Strips A3 and B4: After Assembly Blocks A51 and B52 are assembled, Assembly Strips A3 and B4 are connected. First, align Assembly Strip A3 (with Assembly Block A51) with Assembly Strip B4 (with Assembly Block B52), ensuring that the snap-fit ​​block 512 on the side wall of Assembly Block A51 aligns with the insertion interface 522 on the side wall of Assembly Block B52. Because the snap-fit ​​block 512 has a funnel-shaped structure, when the snap-fit ​​block 512 and the insertion interface 522 touch, the inclined wall guides the self-correction, ensuring that Assembly Blocks A51 and B52 are quickly aligned to prevent displacement during connection.

[0050] Gradually move assembly strips A3 and B4, bringing the opposing sides of assembly blocks A51 and B52 closer together. During this process, the clamping posts 541 in assembly blocks A51 and B52 are both in an outward-extending position, moving together with the fender body 1 and the frame body 2. As the distance between assembly blocks A51 and B52 gradually decreases, the outward-extending sides of their clamping posts 541 slowly touch. Then, move the fender body 1, and the clamping posts 541, after being pressed, move towards the movement opening 513. The spring member B545 shortens under the pressure of the outer ring 544, forming a reverse deformation force.

[0051] As the clamping column 541 moves into the movable opening 513, its inward side pulls and rotates the rotating bar 542 connected to it. The rotating bar 542 rotates and presses against the locking column 543 connected to it, causing the locking column 543 to move along the inner wall of the movable opening 513. Both sides of the assembly block A51 and assembly block B52 are equipped with movable openings 513 and connecting parts B54. The locking column 543 in the movable opening 513 on one side moves with the cooperation of the rotating bar 542, and the locking column 543 in the movable opening 513 on the other side moves with the cooperation of the rotating bar 542. The skewed wall on the outward-facing side of the snap-fit ​​post 543 guides the snap-fit ​​post 543 to successfully snap into the snap-fit ​​interface 33 reserved in the assembly strip A3 and assembly strip B4, achieving the purpose of initial connection between assembly block A51 and assembly strip A3, and assembly block B52 and assembly strip B4. At this moment, the side walls of assembly strip A3 and assembly strip B4 touch each other, achieving the initial connection.

[0052] Fastening connection of assembly strips A3 and B4: After assembly strips A3 and B4 come into contact, a fastening connection is performed on assembly strips A3 and B4. Since the lead screw 537 is entirely within the threaded opening 32, initially, the edge of the lead screw 537 does not protrude from the threaded opening 32. During the tightening of the lead screw 537, one side of the lead screw 537 slowly passes through the threaded opening 32 and comes into contact with the edge of the linkage bar 535. Then, the lead screw 537 is tightened, and the edge of the lead screw 537 applies pressure to the edge of the linkage bar 535, causing the linkage bar 535 to move along the inner wall of the assembly opening 511.

[0053] When the linkage bar 535 moves, the linkage plate 536 fixed to it moves together. The teeth on the linkage plate 536 and the linkage table 534 mesh with each other, pulling the linkage table 534 to rotate in the opposite direction. The linkage table 534 pulls the rotating bar 531 fixed to it to rotate in the opposite direction around the pin on it. The spring A533 clamped to the pin rotates and deforms, forming a reverse deformation force.

[0054] When the rotating bar 531 rotates in the opposite direction, the arched bar 532, which is fixed to its outward side, rotates together and slowly moves out of the assembly opening 511, extending towards one side of the assembly block B52. Then, tighten the screw 537 until it is fully rotated, at which point the arched bar 532 is completely engaged in the arched opening 521 of the assembly block B52, with the outer wall of the arched bar 532 and the inner wall of the arched opening 521 in close contact, thus achieving a tight connection between the assembly block A51 and the assembly block B52, and achieving a tight connection between the assembly bar A3 and the assembly bar B4.

[0055] At this moment, the entire edge of the lead screw 537 extends into the threaded opening 32, without protruding from the assembly strip A3. The arched strip 532, the clamping post 541, and the snap-fit ​​post 543 are all concealed within the assembly blocks A51 and B52, or within the fender body 1 and the frame body 2, ensuring the aesthetic appearance of the assembly of the fender body 1 and the frame body 2. Furthermore, the mating of the snap-fit ​​block 512 and the insert 522, the snap-fit ​​mating of the snap-fit ​​post 543 and the snap-fit ​​interface 33, and the interlocking cooperation of the arched strip 532 and the arched opening 521 form a multi-layered connection structure, greatly enhancing the reliability of the connection and preventing loosening and disintegration at the connection point.

[0056] With assembly strips A3 and B4 securely connected, within the connecting portion B54, the clamping post 541 is pressed and retracted into the variable opening 513, and the snap-fit ​​post 543 extends out from the variable opening 513 and snaps into the snap-fit ​​interface 33. The cooperation of the snap-fit ​​post 543 and the snap-fit ​​interface 33 achieves a reliable connection between assembly block A51 and assembly strip A3, and between assembly block B52 and assembly strip B4, ensuring that assembly block A51 and assembly block B52 are firmly connected to the fender body 1 and the frame body 2. The spring-loaded component B545 is in a shortened state, storing energy. When assembly strips A3 and B4 disassemble, the spring-loaded component B545 releases energy, causing the clamping post 541 to return to its extended state, and the snap-fit ​​post 543 to retract into the variable opening 513.

[0057] Furthermore, the rotating bar 531 within the connecting part A53 rotates in the opposite direction to its furthest point with the cooperation of the linkage table 534, linkage bar 535, and linkage plate 536, and the arched bar 532 is completely engaged within the arched opening 521 in the assembly block B52. The spring-loaded component A533 is in a deformed state within the rotating bar 531, storing energy. When the lead screw 537 is subsequently rotated out, the spring-loaded component A533 can release the energy, allowing the rotating bar 531 to rotate back to its original position in the forward direction.

[0058] The arched strip 532 and the arched opening 521 are mutually compatible, with the outer wall of the arched strip 532 and the inner wall of the arched opening 521 in close contact, forming a comprehensive and tight fit that enhances the stability of the connection. When the assembly strip A3 and assembly strip B4 are subjected to lateral pulling forces, the cooperation between the arched strip 532 and the arched opening 521 can withstand strong pulling forces, preventing the fender body 1 from disintegrating from the frame body 2. Furthermore, during use, the fender body 1 and the frame body 2 are subjected to various forces, and the hook-like structure of the arched strip 532 and the arched opening 521 allows the connection structure to adapt to forces from all directions. Regardless of the origin of the external force, the arched strip 532 has suitable support within the arched opening 521, and the inner wall of the arched opening 521 provides comprehensive restraint to the arched strip 532, preventing omnidirectional movement and ensuring the reliability of the connection. Furthermore, both the arched strip 532 and the arched opening 521 are arched. When the arched strip 532 is engaged in the arched opening 521, the surfaces of the two parts that are in contact with each other are arched. This arched surface allows the force to be evenly distributed along the arched surface, ensuring the service life of the connection part A53. The cooperation between the arched strip 532 and the arched opening 521 has a self-tightening connection function. After the arched strip 532 is fully engaged in the arched opening 521, under normal use, external vibrations cannot cause the arched strip 532 to move out of the arched opening 521 on its own. This is because the arched strip 532 is restrained in several directions within the arched opening 521, and the effect of vibration is insufficient to cause the arched strip 532 to move out.

[0059] Disassembly of Assembly Strips A3 and B4: When disassembling Assembly Strips A3 and B4, simply unscrew the lead screw 537 in the reverse direction. The lead screw 537 returns to the threaded opening 32. At this moment, the pressure exerted by the edge of the lead screw 537 on the linkage strip 535 is released, and the linkage strip 535 loses the support of the lead screw 537. Under the deformation force of the spring-loaded component A533, the rotating strip 531 rotates forward to return to its original position. When the rotating strip 531 rotates forward, the traction linkage table 534 rotates forward, and the linkage table 534 pulls the linkage strip 535 to move in the reverse direction back to its original position via the linkage plate 536. At this moment, when the rotating strip 531 rotates forward, it simultaneously pulls the arched strip 532 out of the arched opening 521 on the assembly block B52, achieving the disassembly of assembly blocks A51 and B52. The fender body 1 is removed from the frame body 2. During the removal, the clamping pins 541 in assembly block A51 and assembly block B52 slowly separate. The deformation of the spring-loaded part B545 causes the clamping pins 541 to return to their original position. When the clamping pins 541 return to their extended position, they are pulled into the locking pins 543 by the rotating bar 2 542 and stored in the variable opening 513. This cancels the fastening connection between assembly block A51 and assembly bar A3, and assembly block B52 and assembly bar B4, achieving the purpose of disassembly and reuse.

[0060] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
