[0021] Compared with the prior art, the beneficial effects of the present application are:

[0023] (2) When the top connecting ring is inserted into the buckle connecting pipe, the push plate is pushed by the top connecting ring and moves upward relative to the buckle connecting pipe. In this process, one end of the positioning stud is extruded by the top surface of the triangular guide plate, so that the end of the positioning stud close to the side connecting pipe is separated from the buckle connecting pipe. As the top connecting ring moves upward, the push plate moves above the positioning stud. At this time, the positioning stud will abut with the top connecting ring under the elastic restoring force of the reset spring, and the shock absorber body is rotated, so that the top connecting ring rotates relative to the push plate. When the top connecting ring is aligned with the clamping hole, the positioning stud will pass through the top connecting ring and the clamping hole and move to the inside of the side connecting pipe under the action of the reset spring. In this way, the supporting horizontal rod can be inserted into the top connecting ring, and the pre-fixing of the shock absorber body can be realized. Then, the nut is placed inside the side connecting pipe, and the nut is screwed into the outside of the positioning stud by rotating the nut, so as to realize the fixation of the shock absorber body. When the nut is screwed, the shock absorber body does not need to be supported, so as to improve the installation efficiency of the shock absorber body and realize the quick installation and disassembly of the shock absorber body, which provides convenience for the disassembly and maintenance of the shock absorber body.

[0024] (3) Before the shock absorber body is disassembled, the bolt at the connection between the second buckle arc-shaped half pipe and the first buckle arc-shaped half pipe is removed, then the flap is actuated, so that the locking pin is separated from the locking clamping hole, then the positioning arc-shaped half pipe is rotated, so that the positioning arc-shaped half pipe on both sides of the lower connecting plate rotates synchronously. When the positioning arc-shaped half pipe is separated from the fixed arc-shaped half pipe, the flap is pressed, so that the locking pin is inserted into the corresponding locking clamping hole, so as to realize the support and limiting of the positioning arc-shaped half pipe. This prevents the positioning arc-shaped half pipe from blocking and hindering the disassembly and installation of the shock absorber body, and provides convenience for the subsequent disassembly and maintenance of the shock absorber body.

[0037] When the motorcycle front suspension of the embodiment of the present application is assembled, the shock absorber body 506 is first placed below the clamping sleeve 502, and then the shock absorber body 506 is pushed so that the top connecting ring 508 is inserted into the buckle connecting pipe 501, in the process, the top connecting ring 508 can be limited by the pre-buckling clamping piece, so as to realize the pre-connection of the lower connecting plate 1 and the shock absorber body 506, and then the shock absorber body 506 can be fixed by a nut, and the shock absorber body 506 does not need to be supported during the fixing process, and then the fixed shock absorber body 506 is shielded and cooled by the cooperation of the heat dissipation package device and the locking clamping piece.

[0038] The shock absorber body 506 of the embodiment of the present application can also be provided with a pressure sensor and a temperature sensor (the specific configuration structure can refer to the prior art, and details are not described here), which are respectively used for detecting the spring deformation pressure of the shock absorber body and the temperature of the shock absorber body in the heat dissipation package device; the pressure sensor and the temperature sensor are connected with an alarm of the motorcycle, when the pressure or temperature detected by the pressure sensor and the temperature sensor exceeds a preset alarm threshold, a safety driving alarm is given through the alarm, a safety prompt is realized, and a driving behavior that damages the suspension system is prompted; in addition, the real-time collected pressure, temperature and other data can be uploaded to the Internet of Vehicles, a user is prompted for safety through background analysis, and the pressure time sequence data can be analyzed to analyze whether the suspension system has a fault, and predictive maintenance is realized.

[0039] As Figure 1 ,Figure 2 、 Figure 6 、 Figure 7 and Figure 8 As shown in FIGS. 1-5, the heat dissipation package holder of the embodiment of the present application comprises a fixed arc-shaped half pipe 505 fixed at the bottom of the clamping sleeve 502, the bottom end of the fixed arc-shaped half pipe 505 is slidably connected with a first buckling arc-shaped half pipe 509, the top of the clamping sleeve 502 is rotatably connected with a swing bracket 510 through a rotating shaft, the swing bracket 510 is located at one side of the buckling pipe 501, the bottom end of the swing bracket 510 is fixed with a swing arc-shaped half pipe 511, the bottom end of the swing arc-shaped half pipe 511 is slidably connected with a second buckling arc-shaped half pipe 512; the fixed arc-shaped half pipe 505 is buckled with the swing arc-shaped half pipe 511, the first buckling arc-shaped half pipe 509 is buckled with the second buckling arc-shaped half pipe 512, and the inner cavity after buckling is used for installing the shock absorber body 506; wherein the swing arc-shaped half pipe 511 and the second buckling arc-shaped half pipe 512 are equal in diameter to the fixed arc-shaped half pipe 505 and the first buckling arc-shaped half pipe 509 respectively, and the buckling positions of the swing arc-shaped half pipe 511, the second buckling arc-shaped half pipe 512, the fixed arc-shaped half pipe 505 and the first buckling arc-shaped half pipe 509 can also be provided with sealing pads, so that the design increases the stability of the second buckling arc-shaped half pipe 512 and the first buckling arc-shaped half pipe 509 in protecting the shock absorber body 506, and at the same time improves the fit of the swing arc-shaped half pipe 511 and the fixed arc-shaped half pipe 505, so as to improve the protection effect on the shock absorber body 506.

[0040] In the embodiment of the present application, the outer side of the first buckling arc-shaped half pipe 509 is fixed with a U-shaped cleaning plate 504, the inner wall of the fixed arc-shaped half pipe 505 is provided with a heat dissipation guide piece 534 penetrating to the outer side of the fixed arc-shaped half pipe 505, the heat dissipation guide piece 534 is located at the inner side of the U-shaped cleaning plate 504, one side of the U-shaped cleaning plate 504 is provided with a ventilation hole 533 penetrating to the other side of the U-shaped cleaning plate 504. When the first buckling arc-shaped half pipe 509 and the second buckling arc-shaped half pipe 512 are slidably matched with the fixed arc-shaped half pipe 505 and the swing arc-shaped half pipe 511, the U-shaped cleaning plate 504 is movably matched with the heat dissipation guide piece 534, and the heat dissipation effect is improved. Wherein the heat dissipation guide piece 534 needs to avoid the stroke of the relative movement of the first buckling arc-shaped half pipe 509 and the fixed arc-shaped half pipe 505.

[0041] In the embodiment of the present application, when the shock absorber body 506 is fixedly connected with the lower connecting plate 1, the shock absorber body 506 is located at the inner side of the fixed connection arc-shaped half pipe 505 and the first buckling arc-shaped half pipe 509, and the shock absorber body 506 is shielded by the fixed connection arc-shaped half pipe 505 and the first buckling arc-shaped half pipe 509. Then, the second buckling arc-shaped half pipe 512 is pressed, and the relative rotation of the positioning frame 510 and the clamping sleeve 502 causes the side of the positioning arc-shaped half pipe 511 to be attached to the side of the fixed connection arc-shaped half pipe 505, and the side of the second buckling arc-shaped half pipe 512 to be attached to the side of the first buckling arc-shaped half pipe 509. At this time, the first buckling arc-shaped half pipe 509 and the second buckling arc-shaped half pipe 512 are connected by bolts at one end, so that the shock absorber body 506 can be wrapped and protected. When the shock absorber body 506 shrinks due to shock absorption, the positioning arc-shaped half pipe 511 moves downward relative to the second buckling arc-shaped half pipe 512, and the fixed connection arc-shaped half pipe 505 moves downward relative to the first buckling arc-shaped half pipe 509. In this way, the shock absorber body 506 can be protected without affecting the shock absorption of the shock absorber body 506. At the same time, the heat generated by the expansion and contraction of the shock absorber body 506 is transferred to the outer side of the fixed connection arc-shaped half pipe 505 through the heat dissipation guide piece 534. When the fixed connection arc-shaped half pipe 505 moves relative to the first buckling arc-shaped half pipe 509, the heat dissipation guide piece 534 slides on the inner side of the U-shaped cleaning plate 504, so as to prevent foreign matter from falling on the outer side of the heat dissipation guide piece 534 and affecting the heat dissipation effect. In this way, the shock absorber body 506 can be protected without affecting the heat dissipation of the shock absorber body 506, improving the shock absorption effect and increasing the service life of the shock absorber body 506.

[0042] As shown in Figure 8 , the length of the heat dissipation guide piece 534 is greater than the width of the U-shaped cleaning plate 504, and the two sides of the heat dissipation guide piece 534 are in clearance fit with the inner wall of the U-shaped cleaning plate 504, reducing the resistance of the U-shaped cleaning plate relative to the heat dissipation guide piece. By setting this structure, when the fixed connection arc-shaped half pipe 505 moves relative to the first buckling arc-shaped half pipe 509, the heat dissipation guide piece 534 moves along the U-shaped cleaning plate 504, which can clean the outer wall of the heat dissipation guide piece 534 and prevent dust from adhering to the surface of the heat dissipation guide piece 534, thereby affecting the heat dissipation of the heat dissipation guide piece 534. It can also actively dissipate heat due to relative movement.

[0043] As shown in Figure 1 and Figure 2 , the bottom end of the second buckling arc-shaped half pipe 512 and the first buckling arc-shaped half pipe 509 is provided with a through hole matched with the bottom of the shock absorber body 506, so as to realize the installation of the shock absorber body 506.

[0044] As shown in Figure 1 , Figure 3 , Figure 4 andFigure 5 As shown, the pre-connector includes a hexagonal sleeve 518 fixed to the buckle connecting pipe 501 near the center of the steering shaft 2, and guide grooves 516 are formed on both sides of the hexagonal sleeve 518. The side connecting pipe 503 is fixed to the side of the buckle connecting pipe 501 away from the hexagonal sleeve 518. The buckle connecting pipe 501 is provided with a clamping hole 527 that penetrates from one side to the other side of the buckle connecting pipe 501, that is, the clamping hole 527 penetrates along the radial direction of the buckle connecting pipe. The clamping hole 527 and the center of the side connecting pipe 503 are coaxial. The top of the buckle connecting pipe 501 is inserted with a guide rod 520 that penetrates into the inside of the buckle connecting pipe 501. The bottom of the guide rod 520 is fixed with a push plate 524. The top of the guide rod 520 is fixed with a limiting plate 521 located above the buckle connecting pipe 501. The bottom of the limiting plate 521 is provided with a top spring 522 connected to the top of the buckle connecting pipe 501. The top spring 522 is located on one side of the guide rod 520. The inside of the hexagonal sleeve 518 is slidably connected with a hexagonal clamping block 517. The hexagonal clamping block 517 is guided and matched with the guide groove 516. The bottom of the lower connecting plate 1 is provided with a fixed plate 515 located between the mounting frame 3 and the hexagonal sleeve 518. One end of the hexagonal clamping block 517 close to the fixed plate 515 is provided with a return spring 523 connected to the fixed plate 515. The end of the hexagonal clamping block 517 away from the return spring 523 is fixed with a supporting horizontal rod 519. The supporting horizontal rod 519 extends to the inside of the buckle connecting pipe 501 through the clamping hole 527. One end of the supporting horizontal rod 519 is fixed with a positioning stud 528. The bottom of the guide rod 520 is fixed with a push plate 524. The top of the push plate 524 is fixed with a triangular guide plate 526. The top of the triangular guide plate 526 is provided with a blocking strip 525 located between the positioning stud 528 and the side connecting pipe 503.

[0045] When the top link ring 508 is inserted into the buckle connecting pipe 501, the push plate 524 is pushed upward relative to the buckle connecting pipe 501 by the top link ring 508, and in the process, one end of the positioning stud 528 is pressed by the top inclined surface of the triangular guide plate 526, so that the end of the positioning stud 528 close to the side connecting pipe 503 is separated from the buckle connecting pipe 501. When the push plate 524 moves to the upper side of the positioning stud 528, the positioning stud 528 is no longer blocked by the push plate 524 and is in close contact with the top link ring 508 under the elastic restoring force of the reset spring 523. By rotating the shock absorber body 506, the top link ring 508 is rotated relative to the push plate 524. When the top link ring 508 is aligned with the clamping hole 527, the positioning stud 528 is inserted into the top link ring 508 and the clamping hole 527 under the action of the reset spring 523 and moves to the inner side of the side connecting pipe 503. In this way, the supporting cross rod 519 is inserted into the top link ring 508, and the pre-fixing of the shock absorber body 506 is realized. Then, the nut is placed on the inner side of the side connecting pipe 503, and the nut is screwed into the outer side of the positioning stud 528 by rotating the nut, so as to fix the shock absorber body 506. When the nut is screwed, the shock absorber body 506 does not need to be supported, and the hexagonal sleeve 518 rotates to limit the rotation of the hexagonal block 517, thereby improving the installation efficiency of the shock absorber body 506. When the shock absorber body 506 is disassembled, the nut connected with the positioning stud 528 is removed, and then the hexagonal block 517 is pulled towards the fixed plate 515, so that the positioning stud 528, the supporting cross rod 519 and the top link ring 508 are separated. At this time, the push plate 524 is restored, and then the hexagonal block 517 is loosened, so that one end of the supporting cross rod 519 is in close contact with the blocking strip 525, thereby realizing the quick installation and disassembly of the shock absorber body 506, and providing convenience for the disassembly and maintenance of the shock absorber body 506.

[0046] As shown in Figure 5 , the outer side of the push plate 524 is in close contact with the inner wall of the buckle connecting pipe 501, and the free end of the positioning stud 528 is a spherical structure, thereby reducing the friction between the positioning stud 528 and the blocking strip 525 and the triangular guide plate 526, thereby prolonging the service life of the positioning stud 528.

[0047] As shown in Figure 3 , Figure 6 , and Figure 7 , the locking connecting piece comprises a synchronous shaft 529 fixed to one side of the swing frame 510, one end of the lower connecting plate 1 is fixed with a side block 513, the side block 513 is located above the synchronous shaft 529, and the side block 513 is rotatably connected with a flap 514 through a rotating shaft on one side of the side block 513.
