Technical Field

The present invention relates to a suspension device, and more particularly to a suspension device for a bicycle.

Background

In recent years, the market of bicycles has been developed vigorously, and both racing-type high-end bicycles and public-type bicycles for leisure and entertainment are popular among consumers. When the bicycle cruises on the road surface, the vibration on the ground is transmitted to the handlebar through the handlebar vertical rod, and finally is absorbed by the hands of the rider. The fatigue of the rider is easily caused under the long-term riding. Therefore, the driver's vertical rod with shock-absorbing function should be transported, and the shock-absorbing method is generally to install an elastic buffer between two components of the driver's vertical rod.

However, if the two components are not tightly bonded, the rider may easily get a gap between the two components when performing the drawing process, which affects the rigidity of the two components. In addition, the shock absorption strength (damping value) of the buffering member required by the driver's upright post is different according to different driving environments, different driving habits, and the like, but the shock absorption strength of the existing driver's upright post with the shock absorption function can only be changed by replacing the buffering member, which is inconvenient for users.

Detailed Description

Fig. 1 is a perspective view of a suspension device according to an embodiment of the invention. Referring to fig. 1, the suspension device 100 of the present embodiment is, for example, a driver's vertical rod, which is suitable for a bicycle. The suspension device 100 includes a first component 110 and a second component 120 connected together. The first assembly 110 is adapted to be coupled to a first member of a bicycle, such as a frame of the bicycle, through an assembly hole 112a of a body 112 thereof, and the second assembly 120 is adapted to be coupled to a second member of the bicycle, such as a handlebar of the bicycle, through an assembly hole 122a of a body 122 thereof, but the present invention is not limited thereto.

FIG. 2 is a perspective view of a portion of the shock absorbing device of FIG. 1. FIG. 3 is an exploded view of the suspension of FIG. 1. Fig. 4 shows a partial structure of the suspension device of fig. 1. Referring to fig. 2 to fig. 4, the suspension device 100 of the present embodiment further includes two pivot members 130 and a cushion member 140. The first member 110 has two conical holes 114a and the second member 120 has two locking holes 122 b. When the first component 110 is connected to the second component 120, each locking hole 122b and each conical hole 114a have the same central axis a, and the two conical holes 114a are located between the two locking holes 122 b.

In detail, each of the hinges 130 has a locking portion 134, and the locking portion 134 is locked to the locking hole 122b of the second assembly 120, for example, in a screw manner. Each pivot member 130 also has a conical portion 132, the conical portion 132 having a taper that is, for example, the same as the taper of the conical bore 114 a. The two conical portions 132 extend into the two conical holes 114a respectively to pivotally connect the first component 110 and the second component 120, and the first component 110 and the second component 120 are limited between the two pivoting members 130. Each conical portion 132 abuts against the inner wall of the corresponding conical hole 114a, and the conical portion 132 abuts against the inner wall of the conical hole 114a by the locking force between the locking portion 134 of the pivot 130 and the locking hole 122b of the second component 120, so as to ensure that no gap is generated between the conical portion 132 and the conical hole 114a by the mutual fit of the conical portion 132 and the conical hole 114 a. Thus, when the rider of the bicycle takes out the bicycle, the first assembly 110 and the second assembly 120 are not separated from each other by the operation of pulling the handle (such as taking out the bicycle), and the rigidity of the suspension device 100 is maintained.

In this embodiment, the suspension device 100 further includes a lock attachment 150. The first element 110 has a through hole 114b as shown in fig. 3, the through hole 114b is connected between the two conical holes 114a, and the locking member 150 is locked between the two pivoting members 130 through the through hole 114b, so that the overall structure is more stable and is not easy to be released.

The buffer 140 of the present embodiment is made of an elastic material and disposed between the first component 110 and the second component 120. When the first element 110 and the second element 120 rotate relative to each other with the central axis a of the conical hole 114a as the rotation axis, the buffer 140 can buffer the interaction force of the first element 110 and the second element 120, thereby achieving the shock-absorbing effect.

In addition, the second assembly 120 of the present embodiment includes a pre-pressing structure 124. The cushion 140 is disposed between the main body 112 of the first element 110 and the pre-pressing structure 124, and the pre-pressing structure 124 can apply a pre-pressing force to the cushion 140. As mentioned above, the pre-pressing structure 124 is utilized to pre-press the cushion member 140, so that the user can change the shock absorption strength of the cushion member 140 by adjusting the pre-pressing force applied to the cushion member 140 by the pre-pressing structure 124 without replacing the cushion member 140, thereby improving the convenience of the shock absorbing device 100 in use.

The following describes the arrangement relationship between the buffer 140 and the first element 110 in this embodiment in detail. Referring to fig. 2, the first element 110 of the present embodiment includes a protrusion 114, the protrusion 114 protrudes from the main body 112 of the first element 110 into the main body 122 of the second element 120, and the conical hole 114a and the through hole 114b of the first element 110 are formed in the protrusion 114. The buffer 140 includes two buffer portions 142 and a connecting portion 144, the two buffer portions 142 are respectively located at two opposite sides of the protruding portion 114 and abut against the main body 112 of the first component 110, and the connecting portion 144 is connected between the two buffer portions 142 and extends along an outer edge of the protruding portion 114. In the embodiment, the thickness of each buffer portion 142 is greater than that of the connecting portion 144, so that the weight can be reduced, and the operation of each buffer portion 142 can be more sensitive.

The following describes in detail the arrangement of the pre-pressing structure 124 of the present embodiment. Referring to fig. 2 and fig. 3, in the present embodiment, the pre-pressing structure 124 includes a pre-pressing member 124a and a screw member 124 b. The cushion 140 is disposed between the first component 110 and the pre-pressing element 124a, and the screw element 124b is screwed to the main body 122 of the second component 120 and pushes the pre-pressing element 124a against the cushion 140. The user can rotate the screw 124b to change the pre-pressure applied by the pre-pressing piece 124a to the buffer 140. Specifically, the screw 124b has, for example, an external thread, and the body 122 of the second component 120 has, for example, a corresponding internal thread for screwing the screw 124 b.

Fig. 5A shows the second assembly of fig. 1 tilted upward. Fig. 5B shows the second assembly of fig. 1 tilted downward. The first component 110 of the present embodiment is adapted to be assembled to the frame of the bicycle along an assembly axis Z perpendicular to a reference plane S (e.g. a horizontal plane), for example, parallel to the direction of gravity. Further, the user can assemble the suspension device 100 to the bicycle with the second assembly 120 tilted upward with respect to the reference plane S as shown in fig. 5A, or can reverse the suspension device 100 and assemble the suspension device 100 to the bicycle with the second assembly 120 tilted downward with respect to the reference plane S as shown in fig. 5B.

In view of the above, the shock absorbing device 100 of the present embodiment includes at least one positioning post 160 (two positioning posts are shown in fig. 3), the first assembly 110 has two positioning holes H1, H2 corresponding to each positioning post 160, and the second assembly 120 has a positioning slot T corresponding to each positioning post 160. When the user assembles the suspension device 100 to the bicycle with the second assembly 120 tilted upward as shown in fig. 5A, the positioning post 160 is adapted to pass through the positioning slot T and be fixed to the positioning hole H2 and abut against the end of the positioning slot T, so as to prevent the second assembly 120 from rotating upward relative to the first assembly 110 unexpectedly when the rider pulls the handle upward (e.g., during pulling). Conversely, when the user assembles the suspension device 100 to the bicycle with the second assembly 120 tilted downward as shown in fig. 5B, the positioning post 160 is adapted to pass through the positioning slot T and be fixed to the other positioning hole H1 and abut against the other end of the positioning slot T, so as to prevent the second assembly 120 from rotating upward relative to the first assembly 110 unexpectedly when the rider pulls the handle upward (e.g., during pulling). In other words, the positioning posts 160 are engaged with the positioning holes H1, H2, so as to prevent the second assembly 120 from rotating relative to the first assembly 110, thereby providing the rider with a rigid choice.

Further, since the cushioning member 140 of the present embodiment has two opposite cushioning portions 142 as shown in fig. 2 and 3, and can achieve a bidirectional shock absorption effect when the first assembly 110 and the second assembly 120 rotate relatively, no matter the user assembles the shock absorbing device 100 in the manner shown in fig. 5A or fig. 5B, a good shock absorbing capability can be achieved.

Although the present invention has been described with reference to the above embodiments, it should be understood that various changes and modifications can be made therein by those skilled in the art without departing from the spirit and scope of the invention.
