Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] Embodiment 1, please refer to Figures 1-3 , the present invention is a carbon fiber fender with high connection strength, including a fixed component 100, including a fender body 101, and a vehicle body 102 disposed on one side of the fender body 101;

[0036] The connecting component 200 includes a fixing component 201 disposed inside the fender body 101, a connecting component 202 disposed inside the fixing component 201, a driving component 203 disposed inside the connecting component 202, and a receiving component 204 disposed inside the vehicle body 102.

[0037] Specifically, the fixing component 201 includes a connecting pin 201a disposed inside the fender body 101, a fixing plate 201b disposed at the end of the connecting pin 201a, and the fixing plate 201b is located on the outer side of the fender body 101, a threaded rod 201c disposed at the other end of the connecting pin 201a, and a fastening nut 201d sleeved on the outer wall of the threaded rod 201c; wherein, the threaded rod 201c and the fastening nut 201d are threadedly connected. The connecting component 202 includes a limiting cylinder 202a disposed inside the connecting pin 201a, a limiting hole 202b penetrating through the side wall of the limiting cylinder 202a, a cross block 202c disposed inside the limiting hole 202b, an intrusion block 202d disposed at the end of the cross block 202c, and a reinforcing frame 202e disposed inside the limiting cylinder 202a; wherein, the number of the limiting holes 202b corresponds to the number of the cross blocks 202c one by one, and the intrusion block 202d is slidably connected to the reinforcing frame 202e.

[0038] Furthermore, the driving component 203 includes a groove 203a opened at the rear side inside the limiting cylinder 202a, a first support rod 203b disposed inside the groove 203a, a rotating disc 203c disposed inside the limiting cylinder 202a, and a second connecting rod 203d disposed inside the rotating disc 203c; wherein, the first support rod 203b is fixedly connected to the cross block 202c, the second connecting rod 203d is fixedly connected to the cross block 202c, the rotating disc 203c is rotatably connected to the limiting cylinder 202a. The receiving component 204 includes a through hole 204a penetrating through the side wall of the vehicle body 102, and a receiving groove 204b opened inside the through hole 204a; wherein, the width of the through hole 204a is the same as the width of the intrusion block 202d.

[0039] The operation process of this embodiment is as follows: First, rotate the rotating disk 203c. Among them, a second connecting rod 203d slides inside the rotating disk 203c, and a cross block 202c is fixed at the end of the second connecting rod 203d. Therefore, as the rotating disk 203c rotates, it will drive the cross block 202c to move. In addition, a first support rod 203b is fixed at the other end of the cross block 202c, and the first support rod 203b slides inside the groove 203a, thereby restricting the movement of the cross block 202c and enabling the cross block 202c to move linearly. In addition, the cross block 202c is also arranged inside the limiting hole 202b, and a reinforcing frame 202e is slidably connected to the inward end of the cross block 202c, thereby ensuring the stable movement of the reinforcing frame 202e. In addition, when the cross block 202c expands outward, it will be stuck into the inside of the receiving groove 204b to complete the connection between the fender body 101 and the vehicle body 102. In addition, by rotating the fastening nut 201d, a further fastening connection is made between the fender body 101 and the vehicle body 102, realizing the multi-stage connection between the fender body 101 and the vehicle body 102, and indirectly improving the connection strength between the fender body 101 and the vehicle body 102.

[0040] Example 2. Refer to Figure 4 , on the basis of Example 1, the rotating component 300 includes a rotating component 301 arranged on one side of the fixed component 201, and a reset component 302 arranged on one side of the rotating component 301.

[0041] Specifically, the rotating component 301 includes a rotating shaft 301a arranged at the end of the limiting cylinder 202a, a ratchet 301b sleeved on the outer wall of the rotating shaft 301a, a ratchet tooth 301c arranged on one side of the ratchet 301b, and a handle 301d arranged at the end of the rotating shaft 301a.

[0042] Furthermore, the reset component 302 includes a fixed cylinder 302a arranged on one side of the fixed plate 201b, a connecting plate 302b arranged inside the fixed cylinder 302a, a reset spring 302c arranged between the fixed cylinder 302a and the connecting plate 302b, and a pull rod 302d arranged inside the reset spring 302c.

[0043] The operation process of this embodiment is as follows: Among them, the rotating shaft 301a is fixedly connected to the rotating disc 203c. A handle 301d is fixed to the other end of the rotating shaft 301a to facilitate the rotation of the handle 301d. In addition, a ratchet 301b is fixed to the outer wall of the rotating shaft 301a. A ratchet tooth 301c is arranged on one side of the ratchet 301b, and the ratchet tooth 301c can just catch the ratchet 301b to prevent the ratchet 301b from rotating. In addition, a connecting plate 302b is fixed to the top end of the ratchet tooth 301c and slides inside the fixed cylinder 302a through a return spring 302c. When the return spring 302c is in its original state, the ratchet tooth 301c will always fix the ratchet 301b to prevent rotation. When the pull rod 302d is pulled upward, the ratchet tooth 301c disengages from the ratchet 301b. At this time, the rotating shaft 301a can rotate freely, indirectly moving the intrusion block 202d. Then, after releasing the handle 301d, the ratchet tooth 301c will reset to fix the ratchet 301b again to prevent the rotating shaft 301a from rotating and moving the intrusion block 202d.

[0044] Embodiment 3. Please refer to Figure 5 , based on Embodiment 1 and Embodiment 2, it further includes a shock-absorbing component 400, which includes a buffer assembly 401 arranged between the fender body 101 and the vehicle body 102, and a pneumatic assembly 402 arranged inside the buffer assembly 401;

[0045] The buffer assembly 401 includes a fixed sleeve 401a fixed to the front end of the vehicle body 102, a telescopic rod 401b arranged inside the fixed sleeve 401a, a baffle 401c arranged at the end of the telescopic rod 401b, and a buffer spring 401d arranged between the baffle 401c and the fixed sleeve 401a.

[0046] Specifically, the pneumatic assembly 402 includes a receiving groove 402a opened on the inner wall of the fixed sleeve 401a, a communication channel 402b opened on the inner wall of the fixed sleeve 401a, an arc spring 402c arranged inside the receiving groove 402a, and a blocking plate 402d arranged on the inner side of the arc spring 402c.

[0047] The operation process of this embodiment is as follows: When the fender body 101 or the vehicle body 102 vibrates, the buffer spring 401d will deform at this time, generating a force opposite to the vibration, thereby offsetting the vibration and indirectly achieving the purpose of reducing noise. In addition, an airbag is provided inside the buffer spring 401d. When the buffer spring 401d is compressed, the airbag will also be compressed, and the generated gas will finally push open the blocking plate 402d through the communication channel 402b and then spray out. Moreover, the blocking plate 402d has a certain angle and all biases towards the telescopic rod 401b, so that the sprayed gas sprays towards the buffer spring 401d, completing the cleaning of the buffer spring 401d and preventing dust from accumulating on the surface of the buffer spring 401d, increasing the friction between the fixed sleeve 401a and the buffer spring 401d, increasing wear, and thus generating noise.
