Description

Technical Field

[0001] The utility model relates to a telescopic rod structure and a bicycle, and in particular to a telescopic rod structure and a bicycle capable of limiting travel distance. Background Art

[0002] Generally speaking, bicycles utilize telescopic rods to adjust the height of the seat or stem. Existing telescopic rod structures vary the length of the rod by adjusting the distance between the upper and lower tubes. However, these existing telescopic rod structures do not have a maximum travel limit. This means that adjustments often result in the rod resetting to the factory-set maximum seat height or maximum stem height. Consequently, the previously adjusted seat or stem height cannot be remembered each time, resulting in inconvenience. Therefore, developing a telescopic rod structure with self-adjustable maximum travel height to facilitate user adjustment of the seat or stem height has become an important and pressing industry challenge.

[0024] Please refer to Figure 1 and Figure 2 ,in Figure 1 A three-dimensional diagram of the telescopic rod structure 100 according to the first embodiment of the present invention is shown. Figure 2 Draw Figure 1 Exploded view of the telescopic rod structure 100 in the first embodiment. Figure 1 and Figure 2 As can be seen, the telescopic rod structure 100 includes a lower tube 110, an upper tube 120, a support tube 130, a control module, a locking tube 160 and an adjustment assembly 140 (marked at Figure 3 ).

[0025] The lower tube 110 includes a first end 111 and a second end 112, which are opposite to each other. The upper tube 120 is inserted into the lower tube 110 from the first end 111 thereof and is adapted to move relative to the lower tube 110. The upper tube 120 and the lower tube 110 define a receiving space. The support tube 130 is disposed in the receiving space, with one end adjacent to the first end 111 of the lower tube 110 and the other end adjacent to the second end 112 of the lower tube 110.

[0026] The control module is located in the accommodating space and includes a valve tube 151, at least one push-up member 152, a control valve 153 and a perforating element 154, wherein one end of the valve tube 151 is connected to one end of the support tube 130, and the valve tube 151 includes at least one accommodating hole 151a; the push-up member 152 is movably located in the accommodating hole 151a; the control valve 153 is movably located in the valve tube 151 and includes at least one recess 153a; the perforating element 154 is arranged in the internal space of the valve tube 151, and the perforating element 154 includes at least one perforating hole 154a.

[0027] The engaging tube 160 is located between the inner wall of the upper tube 120 and the outer wall of the valve tube 151 and is linked to the upper tube 120. The engaging tube 160 includes a plurality of engaging portions 161 and an engaging tail plug 162. The engaging portions 161 are arranged along the axis X of the upper tube 120. The engaging portions 161 are used to selectively engage with the abutting member 152. The engaging tail plug 162 is engaged with one end of the engaging tube 160 adjacent to the support tube 130 and includes a through hole for the valve tube 151 to pass through.

[0028] The adjustment assembly 140 is disposed on the upper tube 120. The adjustment assembly 140 has a socket 140a and includes a fixing member 141, a rotating shaft 142, and a wire 170 (indicated at Figure 3 ). The fixing member 141 is detachably disposed in the socket 140a and exposed on the surface of the upper tube 120. The rotating shaft member 142 is disposed in the upper tube 120. The upper end 170a of the wire body 170 is connected to the rotating shaft member 142, and the lower end 170b of the wire body 170 is connected to the control module, wherein the lower end 170b is passed through the penetration hole 154a and is connected to the perforating element 154. The upper tube 120 switches from a first height to a second height relative to the lower tube 110, and the rotating shaft member 142 converges and limits the wire body 170 to limit the maximum stroke height of the telescopic rod structure 100. Further, in the first embodiment, the fixing member 141 is a screw member, and a thread is correspondingly provided in the socket 140a, and the socket 140a is located at one end of the rotating shaft member 142.

[0029] By cooperating with the rotating shaft 142 and the wire body 170 in the adjustment component 140, the maximum travel height of the telescopic rod structure 100 can be limited, and the maximum seat cushion height or maximum riser height that the user is accustomed to can be memorized. This can avoid resetting to the original factory maximum seat cushion height or maximum riser height when adjusting the height, further preventing the problem of inconvenience in adjusting the seat cushion height or riser height.

[0030] Specifically, when the fixing member 141 is disengaged from the insertion hole 140a, the rotating shaft 142 can be driven to rotate, allowing the wire 170 to be wound around it. When the fixing member 141 is locked or engaged with the insertion hole 140a, the rotating shaft 142 cannot be driven, and the wire 170 cannot be further wound around it. In this way, the maximum travel height of the telescopic rod structure 100 can be stably and conveniently adjusted through the adjustment assembly 140.

[0031] Please refer to Figure 3 and Figure 4 ,in Figure 3 Draw Figure 1 A cross-sectional view of the telescopic rod structure 100 in one state in the first embodiment, Figure 4 Draw Figure 1 A cross-sectional view of another state of the telescopic rod structure 100 in the first embodiment. Figures 2 to 4It can be seen that both the lower tube 110 and the upper tube 120 can be hollow tubular structures. The outer diameter of the upper tube 120 is smaller than the inner diameter of the lower tube 110 and can be inserted into the lower tube 110. One end of the upper tube 120 away from the lower tube 110 can be provided with a connecting component for connecting to the bicycle seat cushion.

[0032] The down tube 110 may further include a down tube tail plug 113 and a seal 114 , wherein the seal 114 is sleeved on the outside of the first end 111 , the down tube tail plug 113 is connected to the second end 112 of the down tube 110 , the support tube 130 is hollow and disposed in the down tube 110 , and one end of the support tube 130 adjacent to the second end 112 can be locked to the stud of the down tube tail plug 113 .

[0033] The telescopic rod structure 100 may further include a sleeve 181 and a buffer spring 182 , wherein the sleeve 181 is sleeved outside the support tube 130 , the buffer spring 182 is located in the accommodating space and sleeved outside the sleeve 181 , and the buffer spring 182 may be pressed between the lower tube tail plug 113 and the engaging tail plug 162 .

[0034] The telescopic rod structure 100 may further include two C-rings C1 and C2 , wherein the C-ring C1 is disposed between the control valve 153 and the perforated element 154 , and the C-ring C2 is disposed on one side of the lower tube tail plug 113 .

[0035] The locking tube 160 may further include a locking tube body 163, wherein a locking portion 161 is recessed in the locking tube body 163, a locking tail plug 162 is locked to one end of the locking tube body 163, and the other end of the locking tube body 163 is fixedly connected to the upper tube 120. Specifically, the locking tube body 163 may be a hollow tubular structure made of metal, so that the two ends of the locking tube body 163 correspond to the two ends of the locking tube 160. Furthermore, the locking tube body 163 may be completely covered with locking portions 161 from top to bottom, and the locking portions 161 are integrally recessed in the locking tube body 163. The integrated locking tube 160 can be first assembled with the control module and then screwed to the upper tube 120, thereby achieving modularization and convenient assembly.

[0036] The control valve 153 may be hollow, and the number of recesses 153a may be one and annular so as to be recessed in the outer wall of the control valve 153. In this way, it can correspond to the accommodating hole 151a at the same time. Furthermore, the side wall of the recess 153a may have an inclined surface so as to push the push member 152 into the accommodating hole 151a when the control valve 153 moves upward along the axis X. One end of the control valve 153 may be radially reduced, and the control module may further include a control spring 155, wherein the control spring 155 is located in the valve tube 151 and is sleeved on the radially reduced end of the control valve 153. The push member 152 may have a ball structure, but the present invention is not limited to this.

[0037] Depend on Figure 3It can be seen that the relative position of the upper tube 120 and the lower tube 110 is the initial maximum travel height of the telescopic rod structure 100. At this time, when the wire 170 has not yet been wound around the rotating shaft 142, the distance H1 is between the upper end 170a and the lower end 170b of the wire 170.

[0038] Depend on Figure 4 As can be seen, the user can first adjust the height of the upper tube 120 relative to the lower tube 110, retracting the upper tube 120 into the lower tube 110 and positioning it. Then, when the wire 170 is wound around the rotating shaft 142, a distance H2 is created between the upper end 170a and the lower end 170b of the wire 170, where H2 is less than H1. At this point, the relative position of the upper tube 120 and the lower tube 110 corresponds to the adjusted maximum travel height of the telescopic rod structure 100. This limits the range within which the abutting member 152 can engage the engaging portion 161, thereby limiting the maximum travel height of the telescopic rod structure 100.

[0039] Depend on Figures 2 to 4 It can be seen that the axis of the rotating shaft 142 is perpendicular to the axis X of the upper tube 120, wherein the rotating shaft 142 is rotated to drive the wire 170 to be wound thereon, limiting the range in which the abutting member 152 can engage with the engaging portion 161, thereby limiting the maximum travel height of the telescopic rod structure 100.

[0040] The shaft 142 has two threading spaces 142a, each of which passes through the center of the shaft 142. The threading spaces 142a are used to pass the wire 170. Specifically, the upper end 170a of the wire 170 passes through one of the threading spaces 142a and is fixedly connected to the shaft 142.

[0041] Furthermore, the adjustment assembly 140 may have an adjustment hole 140b. In the first embodiment, the adjustment hole 140b may be a hexagonal hole located at the other end of the rotating shaft 142, opposite the insertion hole 140a. The configuration of the adjustment hole 140b allows the number of turns of the wire 170 around the rotating shaft 142 to be easily adjusted using a hexagonal wrench, thereby conveniently adjusting the maximum travel height of the telescopic rod structure 100.

[0042] Please refer to Figure 5 and Figure 6 ,in Figure 5 A three-dimensional diagram of a telescopic rod structure 200 according to a second embodiment of the present invention is shown. Figure 6 Draw Figure 5 The exploded view of the telescopic rod structure 200 in the second embodiment. Figure 5 and Figure 6 As can be seen, the telescopic rod structure 200 includes a lower tube 210, an upper tube 220, a support tube 230, a control module, a locking tube 260 and an adjustment assembly 240 (marked at Figure 7 ).

[0043] The lower tube 210 includes a first end 211 and a second end 212, which are opposite to each other. The upper tube 220 is inserted into the lower tube 210 from the first end 211 and is adapted to move relative to the lower tube 210. The upper tube 220 and the lower tube 210 define a receiving space. The support tube 230 is disposed in the receiving space, with one end adjacent to the first end 211 of the lower tube 210 and the other end adjacent to the second end 212 of the lower tube 210.

[0044] The control module is located in the accommodating space and includes a valve tube 251, at least one push-up member 252, a control valve 253 and a perforating element 254, wherein one end of the valve tube 251 is connected to one end of the support tube 230, and the valve tube 251 includes at least one accommodating hole 251a; the push-up member 252 is movably located in the accommodating hole 251a; the control valve 253 is movably located in the valve tube 251 and includes at least one recess 253a; the perforating element 254 is arranged in the internal space of the valve tube 251, and the perforating element 254 includes at least one perforating hole 254a.

[0045] The engaging tube 260 is located between the inner wall of the upper tube 220 and the outer wall of the valve tube 251 and is linked to the upper tube 220. The engaging tube 260 includes a plurality of engaging portions 261 and an engaging tail plug 262. The engaging portions 261 are arranged along the axis X of the upper tube 220. The engaging portions 261 are used to selectively engage with the abutting member 252. The engaging tail plug 262 is engaged with one end of the engaging tube 260 adjacent to the support tube 230 and includes a through hole for the valve tube 251 to pass through.

[0046] The adjustment assembly 240 is disposed on the upper tube 220. The adjustment assembly 240 has a plurality of insertion holes 243b.

The fixing member 241 is detachably disposed in one of the sockets 243b, and the fixing member 241 is exposed on the surface of the upper tube 220. The rotating shaft 242 is disposed in the upper tube 220. The upper end 270a of the wire body 270 is connected to the rotating shaft 242, and the lower end 270b of the wire body 270 is connected to the control module, wherein the lower end 270b is passed through the penetration hole 254a and is connected to the perforating element 254. The upper tube 220 switches from a first height to a second height relative to the lower tube 210, and the rotating shaft 242 converges and limits the wire body 270 to limit the maximum stroke height of the telescopic rod structure 200. Further, in the second embodiment, the fixing member 241 is a snap-fit member, and the adjustment assembly 240 further includes a cover body 243, and the socket 243b is disposed on the cover body 243.

[0047] Specifically, the cover 243 is disposed on the upper tube 220 and covers the rotating shaft 242 , and the insertion hole 243 b is disposed around the side surface of the cover 243 .

[0048] Specifically, when the fixing member 241 is disengaged from the insertion hole 243b, the cover 243 can be driven to rotate the shaft 242 so that the wire 270 is wound thereon; when the fixing member 241 is engaged with one of the insertion holes 243b, the cover 243 and the shaft 242 are both positioned and cannot be driven.

[0049] In addition, the adjustment component 240 may further include a gasket 240 b , wherein the gasket 240 b is disposed in the groove of the fixing member 241 to increase the tightness of the fixing member 241 being locked in the insertion hole 243 b .

[0050] Depend on Figure 6 It can be seen that the lower tube 210 may further include a lower tube tail plug 213 and a seal 214, wherein the seal 214 is sleeved on the outside of the first end 211, the lower tube tail plug 213 is connected to the second end 212 of the lower tube 210, the support tube 230 is hollow and is arranged in the lower tube 210, and the end of the support tube 230 adjacent to the second end 212 can be locked to the stud of the lower tube tail plug 213.

[0051] The telescopic rod structure 200 may further include a sleeve 281 and a buffer spring 282 , wherein the sleeve 281 is sleeved outside the support tube 230 , the buffer spring 282 is located in the accommodating space and sleeved outside the sleeve 281 , and the buffer spring 282 can press between the lower tube tail plug 213 and the locking tail plug 262 .

[0052] The telescopic rod structure 200 may further include two C-rings C1 and C2 , wherein the C-ring C1 is disposed between the control valve 253 and the perforated element 254 , and the C-ring C2 is disposed on one side of the lower tube tail plug 213 .

[0053] The locking tube 260 may further include a locking tube body 263 , wherein the locking portion 261 is recessed in the locking tube body 263 , the locking tail plug 262 is locked to one end of the locking tube body 263 , and the other end of the locking tube body 263 is fixed to the upper tube 220 .

[0054] The control module may further include a control spring 255 , wherein the control spring 255 is located in the valve tube 251 and is sleeved on a radially contracted end of the control valve 253 .

[0055] Please refer to Figure 7 and Figure 8 ,in Figure 7 Draw Figure 5 A cross-sectional view of the telescopic rod structure 200 in the second embodiment, Figure 8 Draw Figure 5 A cross-sectional view of another state of the telescopic rod structure 200 in the second embodiment. Figure 7It can be seen that the relative position of the upper tube 220 and the lower tube 210 is the initial maximum travel height of the telescopic rod structure 200. At this time, when the wire 270 has not yet been wound around the rotating shaft 242, the distance H1 between the upper end 270a and the lower end 270b of the wire 270 is. Figure 8 As can be seen, the user can first adjust the height of the upper tube 220 relative to the lower tube 210, retracting the upper tube 220 into the lower tube 210 and positioning it. Then, when the wire 270 is wound around the rotating shaft 242, a distance H2 is created between the upper end 270a and the lower end 270b of the wire 270, where H2 is less than H1. At this point, the relative position of the upper tube 220 and the lower tube 210 corresponds to the adjusted maximum travel height of the telescopic rod structure 200. This limits the range within which the abutting member 252 can engage the engaging portion 261, thereby limiting the maximum travel height of the telescopic rod structure 200.

[0056] Depend on Figures 6 to 8 It can be seen that the axial direction of the rotating shaft 242 is parallel to the axis X of the upper tube 220, wherein the rotating shaft 242 is connected to the wire body 270 when the cover body 243 is rotated, thereby limiting the range in which the abutting member 252 can engage with the engaging portion 261, thereby limiting the maximum travel height of the telescopic rod structure 200.

[0057] The rotating shaft 242 has a threading space 242a extending axially through the center of the rotating shaft 242. The threading space 242a is used to thread the wire 270, with the threading space 242a extending through the upper end 270a of the wire 270. The cover 243 includes a groove 243a corresponding to the threading space 242a of the rotating shaft 242. The groove 243a provides space for the wire 270 to be wound and routed between the cover 243 and the rotating shaft 242, thereby enhancing the stability of the wire 270 wrapped around the rotating shaft 242 and preventing it from becoming detached.

[0058] In addition, the structures and configurations of the remaining components of the second embodiment are the same as those of the first embodiment, and will not be further described here.

[0059] Please refer to Figure 9 , which shows a three-dimensional schematic diagram of a bicycle 300 according to the third embodiment of the present invention. Figure 9 As can be seen, bicycle 300 includes a frame 310, a seat cushion 320, two wheels 330, and a stem tube 340. The frame 310 includes a telescopic rod structure 311. The stem tube 340 is disposed at the front of the frame 310. The seat cushion 320 is disposed at the rear of the frame 310. The wheels 330 are disposed on the frame 310. The seat cushion 320 is disposed on the top tube of the telescopic rod structure 311 to limit the maximum seat height of the bicycle 300. It should be noted that the telescopic rod structure 311 can be any of the telescopic rod structures described in the first and second embodiments above, and the details are not repeated here.

[0060] Please refer to Figure 10 , which shows a three-dimensional schematic diagram of a bicycle 400 according to the fourth embodiment of the present invention. Figure 10 As can be seen, bicycle 400 includes a frame 410, a seat 420, two wheels 430, and a stem 440. Frame 410 includes a telescopic rod structure 411. Stem 440 is disposed at the front of frame 410, seat 420 is disposed at the rear of frame 410, and wheels 430 are disposed on frame 410. Stem 440 is disposed on the top tube of telescopic rod structure 411 to limit the maximum stem height of bicycle 400. It should be noted that telescopic rod structure 411 can be any of the telescopic rod structures described in the first and second embodiments above, and details are omitted here.

[0061] In summary, the telescopic rod structure of the present invention cooperates with the bicycle through the rotating shaft and the wire body to limit the maximum travel height of the telescopic rod structure, memorizing the user's preferred maximum seat height or maximum stem height. This prevents the seat height or stem height from being reset to the factory default maximum when adjusting the height, further avoiding the inconvenience of adjusting the seat height or stem height. Furthermore, the fixing member maintains the stability of the adjustment assembly, and the adjustment hole of the adjustment assembly allows for convenient adjustment of the maximum travel height of the telescopic rod structure.

[0062] Although the present invention has been disclosed above in terms of implementation methods, they are not intended to limit the present invention. Any person skilled in the art may make slight changes and modifications without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
