Description

Technical Field

[0001] This utility model relates to vehicle carriers and their components, and in particular to a vibration isolation module and a motorcycle equipped with the vibration isolation module. Background Technology

[0002] Motorcycles, as a common mode of transportation in modern life, have obvious advantages in terms of convenience and flexibility. However, due to the structural characteristics of motorcycles, riders are easily affected by vibrations from the vehicle itself and the road surface during riding, thus affecting riding comfort.

[0003] In existing technologies, the seat is typically directly fixed to the frame. This design results in a rigid connection, which easily leads to stress concentration, and combined with engine vibration, the locking structure is more susceptible to damage. Furthermore, these vibrations are transmitted directly from the frame to the seat, and then to the rider, causing discomfort during riding. Therefore, there is an urgent need to develop an effective vibration isolation and damping device to improve the riding comfort and structural durability of motorcycles. Utility Model Content

[0073] See Figure 1 and Figure 2 , Figure 1 This is a schematic diagram of the exterior of a motorcycle according to an embodiment of the present invention; Figure 2 This is a partial structural diagram of an embodiment of the motorcycle according to the present invention, with part of the body shell removed and the seat unit in the open state. The present invention provides a vibration isolation module and a motorcycle equipped with the vibration isolation module. The vibration isolation module 70 is located between the seat unit 50 and the body 10 of the motorcycle M, thereby isolating the body 10 and the seat unit 50, preventing vibrations generated by the body 10 from being directly transmitted to the seat unit 50, and absorbing and reducing vibrations, thus improving the comfort of the rider of the motorcycle M.

[0074] See Figure 1 , Figure 2 and cooperate Figure 3 , Figure 3 This is a partial enlarged structural diagram of a motorcycle according to an embodiment of the present invention. The motorcycle M includes a body 10, a power unit 20, multiple wheels 30, a steering unit 40, a seat unit 50, a pivot assembly 60, and a shock-absorbing module 70. The body 10 includes a frame 11. The power unit 20 is disposed on the frame 11. Each wheel 30 is rotatably disposed on the frame 11, and at least one wheel 30 is poweredly connected to the power unit 20. The steering unit 40 is disposed on the frame 11 and connected to at least one wheel 30. The pivot assembly 60 is disposed between the seat unit 50 and the frame 11 and includes a first fixing part 61, a hinge part 62, and a second fixing part 63. The hinge part 62 is located between the first fixing part 61 and the second fixing part 63, and the second fixing part 63 is connected to the seat unit 50. The shock-absorbing module 70 includes at least one elastic member 71, which is disposed between the body 10 and the first fixing part 61.

[0075] See Figure 1 and Figure 2 The vehicle body 10 is used to carry the power unit 20, wheels 30, steering unit 40, seat cushion unit 50, pivot assembly 60, and vibration isolation module 70. In some embodiments, the vehicle body 10 includes a frame 11 and a shell 12, the shell 12 covering the frame 11 and some components to protect the frame 11 and other components and to provide the designed appearance of the vehicle body 10.

[0076] In some embodiments, the frame 11 extends in height along the height direction D1 and in length and width along the horizontal direction D2. Specifically, the horizontal direction D2 includes a length direction D21 and a width direction D22 that are perpendicular to each other. The frame 11 extends in length along the length direction D21 and in width along the width direction D22, and the aforementioned length direction D21, height direction D1, and width direction D22 are perpendicular to each other. In these embodiments, when the motorcycle M is in use, the motorcycle M is placed flat on the horizontal plane defined by the length direction D21 and the width direction D22, while the height direction D1 is perpendicular to the horizontal plane. The length direction D21, width direction D22, and height direction D1 can also be understood as the X-axis, Y-axis, and Z-axis in three-dimensional space.

[0077] See Figure 1 and Figure 2 The power unit 20 provides driving power to the motorcycle M. In some embodiments, the power unit 20 may be, but is not limited to, an engine power assembly or a motor power assembly. An engine power assembly is a component that converts energy generated by burning fuel into kinetic energy. A motor power assembly is a component that converts electrical energy into kinetic energy.

[0078] See Figure 1 and Figure 2 The wheels 30 are used to drive the overall motorcycle M displacement. In some embodiments, there are at least two wheels 30, which are respectively located at different positions on the frame 11 in the longitudinal direction D21. The steering unit 40 allows the rider to control the steering of the wheels 30. In some embodiments, the steering unit 40 includes at least a front fork and handlebars, with the front fork connected to one of the wheels 30, such as the front wheel, and the handlebars connected to the front fork. In this way, the rider can steer the front wheel by using the handlebars and the front fork.

[0079] See Figures 1 to 3The pivot assembly 60 is pivotally disposed between the vehicle body 10 and the seat unit 50, allowing the seat unit 50 to pivot relative to the vehicle body 10 via the pivot assembly 60. It is worth noting that the position of the pivot assembly 60 on the vehicle body 10 can be changed depending on the configuration of the seat unit 50. In some embodiments, the front end of the motorcycle M is one end of the vehicle body 10 in the longitudinal direction D21, i.e., the end where the steering unit 40 is located; while the other end of the vehicle body 10 in the longitudinal direction D21 is the rear end.

[0080] See Figures 1 to 3 In some embodiments, the motorcycle body 10 of the motorcycle M also includes a storage box 13, and the seat unit 50 can open and close the storage box 13 while pivoting. In these embodiments, the configuration position and pivoting direction of the seat unit 50 can change the opening and closing direction of the storage box 13, thereby forming a front-opening or rear-opening storage box 13.

[0081] See Figures 1 to 3 In some embodiments, the storage compartment 13 is disposed between the two endpoints of the frame 11 along the longitudinal direction D21, and the pivot assembly 60 is disposed at the rear end of the vehicle body 10 and adjacent to the storage compartment 13. In this way, the seat cushion unit 50 can pivot upwards or downwards about the pivot assembly 60 at the rear end of the vehicle body 10. Thus, the seat cushion unit 50 can be lifted at the rear end of the vehicle body 10 to open the storage compartment 13 (e.g., ...). Figure 2 (State); also, the seat cushion unit 50 can be lowered to close the storage box 13 (as shown). Figure 1 (Status), providing a rear-opening storage box 13.

[0082] See Figure 9 and Figure 10 , Figure 9 This is a schematic diagram of another embodiment of the motorcycle of this utility model; Figure 10 for Figure 9 A partial cross-sectional view of selected area 10. In some embodiments, the pivot assembly 60 is disposed on the front side of and adjacent to the storage compartment 13, so that the seat cushion unit 50 can pivot upward or downward about the pivot assembly 60 on the front side of the storage compartment 13. Thus, the seat cushion unit 50 can be lifted upward away from the front side of the storage compartment 13 to open the storage compartment 13; and the seat cushion unit 50 can also be lowered to close the storage compartment 13, providing a front-opening storage compartment 13.

[0083] In some embodiments of the motorcycle M that include the pivot assembly 60, the pivot assembly 60 can be located at any position on the vehicle body 10. For example... Figure 2 , Figure 3In the illustrated embodiment, the first fixing portion 61 of the pivot assembly 60 is disposed on the frame 11, but the present invention is not limited thereto. In some embodiments of the motorcycle M including a storage box 13, the storage box 13 may have an extension covering the frame 11, in which case the first fixing portion 61 of the pivot assembly 60 may be fixed to the extension of the storage box 13. In other embodiments, the body shell 12 of the motorcycle M may extend to the periphery of the storage box 13, so that the first fixing portion 61 of the pivot assembly 60 may be fixed to the body shell 12 around the storage box 13, thereby also providing stable support for the pivot assembly 60. Furthermore, in other embodiments, the pivot assembly 60 may also be directly fixed to the fuel tank (not shown in the figure).

[0084] See Figures 3 to 5 , Figure 4A This is a partial cross-sectional view of an embodiment of the motorcycle according to the present invention, showing the elastic element in a state where it is not forced into tension; Figure 4B This is a partial cross-sectional view of an embodiment of the motorcycle of the present invention, showing the state in which the elastic element is forced into tension; Figure 5 for Figure 2 A cross-sectional view of section 5 in the center circle. The vibration isolation module 70 is used to separate the vehicle body 10 from the seat unit 50 and absorbs the vibrations generated by the vehicle body 10, effectively reducing the vibrations transmitted from the vehicle body 10 to the seat unit 50 and improving the riding comfort of the rider of the motorcycle M. In addition, the vibration isolation module 70 can also avoid a rigid connection between the vehicle body 10 and the seat unit 50, which can effectively improve the reliability and durability of the locking mechanism.

[0085] In some embodiments, the elastic element 71 of the vibration isolation module 70 is made of a material with cushioning capabilities, such as, but not limited to, rubber, silicone, thermoplastic elastomer (TPE), ethylene-vinyl acetate copolymer (EVA), or polycarbonate (PC).

[0086] Therefore, when the motorcycle M is in motion, the vibrations generated by the body 10 are transmitted to the vibration isolation module 70 and are absorbed and blocked by the elastic element 71, thereby greatly reducing the vibration transmission to the seat unit 50 and improving the comfort of the rider on the seat. In addition, the vibration isolation module 70 isolates the body 10 and the seat unit 50 from each other, avoiding stress concentration caused by rigid connection in conventional technology, thereby reducing the risk of component damage and significantly extending the service life of the device.

[0087] See Figures 3 to 5In some embodiments, the pivot assembly 60 is fixed to the vehicle body 10 by locking. In these embodiments, the pivot assembly 60 further includes a plurality of locking attachments 64, the first fixing part 61 includes a plurality of openings 611, each elastic member 71 includes an axial through hole 711, the openings 611 of the first fixing part 61 are fitted onto the elastic member 71, and the locking attachments 64 pass through the axial through holes 711 and are locked to the vehicle body 10. In this way, the elastic member 71 can be fixed to the vehicle body 10 by locking, improving the ease of assembly.

[0088] See Figure 6 This is a cross-sectional schematic diagram of another embodiment of the elastic element of the vibration isolation module in a motorcycle according to an embodiment of the present invention. In some embodiments, the elastic element 71 is a cylinder, and an axial through hole 711 extends through both ends of the elastic element 71 along its axial direction. The shape of the opening 611 of the first fixing part 61 of the pivot assembly 60 corresponds to the shape of the elastic element 71. Preferably, the outer diameter of the elastic element 71 in the unloaded state is slightly larger than the inner diameter of the opening 611 of the first fixing part 61. In this way, by means of the elastic flexibility of the elastic element 71, when the pivot assembly 60 is fitted onto the elastic element 71 with the opening 611 of the first fixing part 61, the first fixing part 61 can slightly compress the elastic element 71 and embed into the elastic element 71, so that the opening 611 of the first fixing part 61 can fit more tightly onto the elastic element 71, ensuring that the vibration of the vehicle body 10 can be reliably absorbed and blocked by the elastic element 71 when passing through the pivot assembly 60, thus ensuring the vibration isolation effect.

[0089] See Figures 3 to 5 In some embodiments, the elastic member 71 is a cylinder with a radial annular groove 712 located on the outer surface of the elastic member 71 between its two axial ends. In these embodiments, the opening 611 of the first fixing portion 61 of the pivot assembly 60 is fitted within the radial annular groove 712 of the elastic member 71. In these embodiments, the radial annular groove 712 includes a parallel and opposing upper surface 7121, a lower surface 7122, and a side surface 7123 connecting the upper surface 7121 and the lower surface 7122, the upper surface 7121 and the lower surface 7122 extending radially perpendicular to the elastic member 71.

[0090] When the first fixing part 61 of the pivot assembly 60 is fitted into the radial annular groove 712 of the elastic member 71 through the opening 611, the inner circumference of the opening 611 abuts against the side surface 7123 of the radial annular groove 712, and the first fixing part 61 is sandwiched between the upper surface 7121 and the lower surface 7122. In this way, in addition to increasing the contact area between the elastic member 71 and the first fixing part 61, the upper surface 7121 and the lower surface 7122 of the radial annular groove 712 can also restrict the axial displacement of the first fixing part 61 in the elastic member 71, while the side surface 7123 can restrict the radial displacement of the first fixing part 61 in the elastic member 71. Accordingly, the first fixing part 61 of the pivot assembly 60 is positioned by the elastic member 71, improving the stability of the pivot assembly 60 on the vehicle body 10.

[0091] See Figure 7 , Figure 7 This is a cross-sectional schematic diagram of another embodiment of the elastic element of the vibration isolation module in a motorcycle according to this utility model. In some embodiments, the elastic element 71 includes a first elastic element 71A and a second elastic element 71B, each being a single sheet, and the first elastic element 71A and the second elastic element 71B respectively include axial through holes 711 corresponding to the number and position of the openings 611. In these embodiments, the first elastic element 71A and the second elastic element 71B respectively abut against the upper and lower surfaces of the first fixing part 61. Thus, the first elastic element 71A and the second elastic element 71B also provide cushioning between the seat unit 50 and the vehicle body 10, and also facilitate assembly.

[0092] See Figures 3 to 6 In some embodiments, the elastic element 71 has an end face 713 at its upper and lower ends in the axial direction, respectively. Please see Figure 3 The vibration isolation module 70 also includes at least one inner bushing 72, which includes a hollow tube 721 and a radial protruding ring 722. The hollow tube 721 is inserted into the axial through hole 711 of the elastic member 71, and the radial protruding ring 722 abuts against one end face 713 (lower end face) of the elastic member 71. In this way, the inner bushing 72 can provide stable support for the elastic member 71, thereby preventing the elastic member 71 from being deformed by pressure when locked by the locking attachment 64.

[0093] In some embodiments, the inner bushing 72 may be made of a material with greater rigidity than the elastic element 71, such as, but not limited to, metals, such as iron, copper, aluminum, or stainless steel. In these embodiments, in addition to providing stable support for the elastic element 71 via the radial convex ring 722, the inner bushing 72 can also pass through the hollow tube 721 of the inner bushing 72 and be locked to the vehicle body 10 when the locking attachment 64 locks the vibration isolation module 70, thus preventing damage to the elastic element 71 during the locking process and extending the service life of the elastic element 71.

[0094] In some embodiments, the number of elastic members 71 matches the number of openings 611 in the first fixing part 61, that is, one elastic member 71 can be fitted onto each opening 611. In this way, the elastic members 71 can be freely adapted to the first fixing part 61 with different numbers of openings 611 or different positions of openings 611.

[0095] See Figure 8 , Figure 8 This is a cross-sectional view of a vibration isolation module for a motorcycle according to an embodiment of the present invention, comprising a one-piece elastic element and a one-piece inner bushing plate. In some embodiments, the vibration isolation module 70 is disposed between the pivot assembly 60 and the vehicle body 10 via a one-piece elastic element 71. In these embodiments, the elastic element 71 includes a gasket portion 714 and a plurality of columnar portions 715, each columnar portion 715 extending from the thickness direction of the gasket portion 714, and each columnar portion 715 having an axial through hole 711. Here, the number and position of the columnar portions 715 on the gasket portion 714 and the openings 611 of the first fixing portion 61 correspond to each other. In this way, each opening 611 of the first fixing portion 61 is fitted onto each columnar portion 715 on the one-piece elastic element 71, and the integral gasket portion 714 can fix the position of each columnar portion 715, thereby reducing assembly steps, reducing the difficulty of the assembly process, and improving assembly convenience.

[0096] In other words, in Figures 3 to 6 In this embodiment, the number of inner bushings 72 corresponds to the number of openings 611 in the first fixing portion 61 of the pivot assembly 60, with each inner bushing 72 passing through one opening 611. Thus, the inner bushings 72 can be freely adapted to the first fixing portion 61 with different numbers or positions of openings 611. However, this invention is not limited thereto, such as... Figure 8 In the embodiment shown, the vibration isolation module 70 may also include a single-piece inner bushing plate 73, through which all the openings 611 on the first fixing part 61 are passed.

[0097] See Figure 8In some embodiments of the vibration isolation module 70, which includes an inner bushing plate 73, the inner bushing plate 73 includes a flat plate portion 731 and a plurality of sleeves 732, each sleeve 732 extending from the thickness direction of the flat plate portion 731. Each sleeve 732 of the inner bushing plate 73 is inserted into an axial through hole 711 of each columnar portion 715 of the elastic member 71, and the flat plate portion 731 abuts against a gasket portion 714 of the elastic member 71. Here, the number and position of the sleeves 732 on the flat plate portion 731 correspond to the openings 611 of the first fixing portion 61. Thus, each sleeve 732 on the single-piece inner bushing plate 73 passes through each opening 611 of the first fixing portion 61 of the pivot assembly 60, and the single-piece flat plate portion 731 can fix the position of each sleeve 732, thereby reducing assembly steps, lowering the difficulty of the assembly process, and improving assembly convenience.

[0098] See Figure 4A In some embodiments, the elastic element 71 has a first height in its axial direction, and the hollow tube 721 of the inner bushing 72 and the sleeve 732 of the inner bushing plate 73 have a second height in the axial direction. The first height is greater than the second height (when the elastic element 71 is not under stress). In some embodiments, the difference between the first height and the second height is 5 millimeters (mm). Therefore, when the elastic element 71 and the inner bushing 72 (or inner bushing plate 73) are assembled onto the vehicle body 10 but not yet locked by the locking attachment 64, the elastic element 71 is slightly higher than the inner bushing 72 (or inner bushing plate 73). When the locking attachment 64 passes through the hollow tube 721 or the sleeve 732 and is locked, the locking attachment 64 can compress the elastic element 71 while locking, causing the elastic element 71 to deform to the same height as the inner bushing 72, thereby making closer contact with the first fixing part 61 of the pivot assembly 60. This ensures that the first fixing part 61 can more closely abut against the elastic element 71, which not only helps with structural stability but also ensures vibration isolation.

[0099] See Figure 2 In some embodiments, the motorcycle M further includes an air filter assembly 80, which is mounted on the frame 11 of the vehicle body 10. The air filter assembly 80 has an upper limit endpoint 81 and a lower limit endpoint 82 along the height direction D1 of the frame 11. The upper limit endpoint 81 is the endpoint of the air filter assembly 80 furthest from the ground along the height direction D1, and the lower limit endpoint 82 is the endpoint of the air filter assembly 80 closest to the ground along the height direction D1. A first imaginary line L1 extends from the upper limit endpoint 81 along the horizontal direction D2, and a second imaginary line L2 extends from the lower limit endpoint 82 along the horizontal direction D2. In these embodiments, the pivot assembly 60 and the vibration isolation module 70 are positioned between the first imaginary line L1 and the second imaginary line L2 along the height direction D1.

[0100] See Figures 1 to 3In some embodiments, the motorcycle M further includes at least one grip portion 90, which extends along the length direction D21 of the frame 11 and is disposed on the frame 11, and is remotely opposite to the steering unit 40, i.e., located at the front and rear ends of the length direction D21, respectively. A pivot assembly 60 and a shock-absorbing module 70 are located between the two corresponding ends of the grip portion 90. Thus, the grip portion 90 is positioned around the seat cushion unit 50, providing a grip for passengers riding the motorcycle M, improving the comfort and safety of riding the motorcycle M.

[0101] See Figure 3 In some embodiments, the motorcycle M further includes a seat support rod 51, which is disposed between the frame 11 and the second fixing portion 63 of the pivot assembly 60. This seat support rod 51 secures the seat unit 50 in the upturned position and also allows the seat unit 50 to close slowly into the storage compartment 13, reducing the risk of the user being pinched by the seat unit 50.
