Description

Technical Field

[0001] This invention relates to the field of bicycle technology, and more particularly to a bicycle remote control device. Background Technology

[0002] The switch handle disclosed in TW M558734 uses the engagement of a first bolt and a clamping member to connect the buckle, connecting member, and lever. If the first bolt is tightened too much, the lever may be difficult to pivot, which is not conducive to seat post height adjustment. In addition, if the mounting angle of the lever needs to be adjusted, the rider needs to loosen the first bolt to make further adjustments. However, when the first bolt is loosened, the buckle may also loosen, forcing the rider to readjust the buckle's position. This will cause the rider a lot of inconvenience in use.

[0003] The handlebar cable control device disclosed in TW M588081 uses the screw engagement between the rod of the connector and the pivot of the fixing part to connect the connecting part, the operating part, and the fixing part together. If the connector is locked too tightly, it is easy to make it difficult for the operating part to pivot, which is not conducive to the adjustment of the seat post height. In addition, if the installation angle of the operating part needs to be adjusted, the rider needs to loosen the connector to make further adjustments. However, when the connector is loosened, the fixing part may also loosen, causing the rider to readjust the position of the fixing part. This will cause many inconveniences for the rider. Summary of the Invention

[0004] The main objective of this invention is to provide a bicycle remote control device that improves operational convenience.

[0005] To achieve the aforementioned main objectives, the drive-by-wire device provided by the present invention includes a harness ring, a connector, a lever, an adjusting screw, and a positioning block. The harness ring has a ring portion and a connecting portion radially connected to the ring portion. The ring portion is fitted onto a handlebar with a harness hole. The connecting portion has a first internal threaded hole radially communicating with the harness hole. The connector has an external threaded shaft and a second internal threaded hole penetrating the external threaded shaft. The external threaded shaft of the connector is screwed into the first internal threaded hole of the harness ring, fixing the two together. The lever has a pivot hole and is pivotally fitted onto the connector with respect to the harness ring, allowing the lever to pivot relative to the harness ring with the connector as its axis under external force. The adjusting screw is screwed into the second internal threaded hole of the connector. The positioning block is located in the harness hole of the harness ring and can be tightened or loosened by the adjusting screw to tighten or loosen the handlebar.

[0006] As can be seen from the above, the wire control device of the present invention uses the connector to assemble the clamp and the lever together and can position the installation angle of the lever. In addition, the adjusting screw is used to press the positioning block against the handlebar. The two do not affect each other, and the installation angle of the lever will not be affected by loosening the adjusting screw. In this way, the purpose of increasing the convenience of operation can be achieved.

[0007] Optionally, the connector further includes a bearing support portion, one end of which is connected to the externally threaded shaft, and the bearing support portion is penetrated by the second internally threaded hole. A bearing is disposed between the pivot hole of the lever and the bearing support portion of the connector, through which the lever can pivot relative to the retaining ring.

[0008] Optionally, the connector further has a head that connects to the other end of the bearing support, and the head has an internal polygonal hole that coaxially communicates with the second internal threaded hole. During assembly, by engaging a tool with the internal polygonal hole, the connector can be driven to rotate, causing the external thread of the connector to engage with the first internal threaded hole of the retaining ring. Furthermore, by inserting another tool through the internal polygonal hole into the second internal threaded hole and engaging it with the adjusting screw, the adjusting screw can be driven to rotate, causing the adjusting screw to push against or release the positioning block.

[0009] Optionally, the connector further has an outer flange connecting the bearing support and the head, and the lever further has an inner flange protruding radially from the bore wall of the pivot hole. The bearing has an inner ring and an outer ring, the inner ring abutting against the end face of the connecting portion of the retaining ring and the outer flange of the connector, and the outer ring abutting against the inner flange of the lever, thereby keeping the bearing in position.

[0010] Optionally, the connector includes a retaining ring connector, a bearing support, and a lever connector. The retaining ring connector has an externally threaded shaft, a second internally threaded hole, and a disc portion connecting to the externally threaded shaft. The outer periphery of the disc portion has an externally threaded portion. The bearing support is disposed within the pivot hole of the lever and has an internally threaded portion and a bearing support portion adjacent to the internally threaded portion. The internally threaded portion of the bearing support is screwed into the externally threaded portion of the retaining ring connector. The lever connector has a bearing support portion and an externally threaded portion coaxially connected to the bearing support portion. The lever also has a third internally threaded hole axially communicating with the pivot hole, and the third internally threaded hole of the lever is screwed into the externally threaded portion of the lever connector. A bearing is disposed between the bearing support portion of the bearing support and the bearing support portion of the lever connector, allowing the lever to drive the lever connector to pivot relative to the retaining ring.

[0011] Optionally, the lever connector also has an internal polygonal hole that passes through the bearing support and the external thread, and the internal polygonal hole coaxially communicates with the second internal thread hole of the retaining ring connector. During assembly, by engaging a tool with the internal polygonal hole, the lever connector can be driven to rotate, so that the external thread of the lever connector is screwed into the third internal thread hole of the lever. In addition, by inserting another tool through the internal polygonal hole into the second internal thread hole and engaging it with the adjusting screw, the adjusting screw can be driven to rotate, so that the adjusting screw pushes or releases the positioning block.

[0012] Optionally, the bearing support member further has an inner flange adjacent to the bearing support portion, the retaining ring connector further has an outer flange adjacent to the bearing support portion, and the lever has an inner flange annularly disposed in the third internal threaded hole; the bearing has an inner ring and an outer ring, the inner ring abutting against the outer flange of the lever connector and the inner flange of the lever, and the outer ring abutting against the inner flange of the bearing support member and the disc portion of the retaining ring connector, so that the bearing is kept in position.

[0075] The applicant hereby clarifies that throughout this specification, including the embodiments described below and the claims in the patent application, all directional terms are based on the directions shown in the accompanying drawings. Secondly, in the embodiments and drawings described below, the same element reference numerals represent the same or similar elements or their structural features.

[0076] Please see Figure 1 and Figure 2 The wire control device 1 of the first embodiment of the present invention includes a bundle ring 10, a wire adapter 16, a connector 20, a lever 30, a bearing 40, an adjusting screw 50, and a positioning block 52.

[0077] The retaining ring 10 has a ring portion 11, the ring portion 11 having a retaining hole 12 and a groove 13, the retaining hole 12 being used to fit onto a handlebar 2 (e.g., Figure 1 As shown), the groove 13 is recessed from the wall of the aperture 12. The clamping ring 10 also has a connecting portion 14 that is radially connected to the aperture 12, the connecting portion 14 having a first internal threaded hole 15 that is radially connected to the aperture 12 and passes through the groove 13.

[0078] The wire adapter 16 has an adapter hole 17 and a wire fixing hole 18. The adapter hole 17 is fitted onto the connecting part 14 of the clamping ring 10, while the wire fixing hole 18 is used for a wire (such as a speed change wire, but not limited to it) to pass through.

[0079] In this embodiment, the connector 20 has a head 21, an outer flange 22 connecting the head 21, a bearing support portion 23 connecting the outer flange 22, and an externally threaded shaft 24 connecting the bearing support portion 23. The head 21 has an inner polygonal hole 25 (in this embodiment, an internal hexagonal hole). The bearing support portion 23 and the externally threaded shaft 24 are coaxially connected by a second internally threaded hole 26 (e.g., ...) in the inner polygonal hole 25. Figure 3 (As shown) it is traversed.

[0080] The lever 30 has a pivot hole 33, a first operating part 34, and a second operating part 35. The pivot hole 33 passes through the inner and outer sides 31 and 32 of the lever 30 and is fitted onto the head 21 and bearing support 23 of the connector 20. The first operating part 34 is located at the front end of the pivot hole 33 for the rider to shift the lever upwards. The second operating part 35 is located at the rear end of the pivot hole 33 for the rider to press down. In addition, the lever 30 also has an annular inner flange 36, which is adjacent to the inner side 31 and protrudes radially from the wall of the pivot hole 33.

[0081] like Figure 3 As shown, the bearing 40 has an inner ring 41, an outer ring 42, and a plurality of rolling elements 43 disposed between the inner ring 41 and the outer ring 42. The bearing 40 is disposed between the pivot hole 33 of the lever 30 and the bearing support portion 23 of the connector 20, so as to allow the lever 30 to pivot relative to the retaining ring 10 with the connector 20 as the axis. Therefore, when the first operating portion 34 of the lever 30 is pushed upward by an external force or the second operating portion 35 of the lever 30 is pressed downward by an external force, the lever 30 can pivot relative to the retaining ring 10 with the connector 20 as the axis, and during the pivoting process, a tightening screw S pulls the cable, so that the cable further controls the operation of related components (e.g., switching gears).

[0082] The adjusting screw 50 is screwed into the second internal threaded hole 26 of the connector 20.

[0083] The positioning block 52 has a positioning part 54 and a pushing part 56. The positioning part 54 is disposed in the groove 13 of the retaining ring 10, and the pushing part 56 is connected to the back of the positioning part 54 and passes through the second internal thread hole 26 of the connector 20.

[0084] During assembly, a tool (e.g., a hex wrench, not shown) is engaged with the inner polygonal hole 25 of the connector 20 and rotated. This causes the external threaded shaft 24 of the connector 20 to be screwed into the first internal threaded hole 15 of the retaining ring 10. Simultaneously, the inner and outer sides of the inner ring 41 abut against the end face 142 of the connecting portion 14 of the retaining ring 10 and the outer flange 22 of the connector 20, respectively. The inner side of the outer ring 42 abuts against the inner flange 36 of the lever 30. This completes the assembly of the retaining ring 10, the cable adapter 16, the lever 30, and the bearing 40. Next, another tool (e.g., a screwdriver, not shown) is engaged with the adjusting screw 50 through the inner polygonal hole 25 of the connector 20 and rotated. This causes the adjusting screw 50 to push against the pushed portion 56 of the positioning block 52. Consequently, the positioning portion 54 of the positioning block 52 presses against the handlebar 2, which is inserted into the retaining hole 12, thus fixing the retaining ring 10 and the handlebar 2 together. Conversely, when the adjusting screw 50 loosens the pushed part 56 of the positioning block 52, the positioning part 54 of the positioning block 52 also loosens the handlebar 2 at the same time, so that the clamp ring 10 can be adjusted or removed from the handlebar 2.

[0085] As can be seen from the above, the wire control device 1 of the present invention first uses the connector 20 to assemble the clamp 10 and the lever 30 together and position the installation angle of the lever 30. Then, the adjusting screw 50 is used to tighten the clamp 10 to the handlebar 2. The two do not affect each other, and the installation angle of the lever 30 will not be affected by loosening the adjusting screw 50. In this way, the purpose of increasing the convenience of operation can be achieved.

[0086] Please continue reading. Figure 4 The wire control device 1' of the second embodiment of the present invention is structurally similar to that of the first embodiment described above, except that the structure of the connector 60 is significantly different.

[0087] In this embodiment, the connector 60 is composed of multiple elements, rather than the single element used in the first embodiment described above. Furthermore, the connector 60 includes a ring connector 70, a bearing support 80, and a lever connector 90, wherein:

[0088] The retaining ring connector 70 has an external threaded shaft 71, a second internal threaded hole 72 passing through the external threaded shaft 71, a disc portion 73 connecting the external threaded shaft 71, and an internal polygonal hole 74 (in this embodiment, an internal hexagonal hole) passing through the disc portion 73 and communicating with the second internal threaded hole 72, wherein an external threaded portion 75 is provided on the outer periphery of the disc portion 73.

[0089] The bearing support 80 has a through hole 81 extending through both opposite ends. The wall of the through hole 81 forms an internal thread portion 82, a bearing support portion 83 adjacent to the internal thread portion 82, and an inner flange 84 adjacent to the bearing support portion 83. Figure 6 As shown, the internal thread 82 of the bearing support 80 is screwed onto the external thread 75 of the retaining ring connector 70, so that the bearing support 80 and the retaining ring connector 70 are assembled together.

[0090] The lever connector 90 has an outer flange 91, a bearing support portion 92 adjacent to the outer flange 91, and an external thread portion 93 adjacent to the bearing support portion 92. The outer flange 91, the bearing support portion 92, and the external thread portion 93 are all penetrated by an internal polygonal hole 94 (in this embodiment, an internal hexagonal hole). Figure 6 As shown, a bearing 40 is disposed between the bearing support portion 92 of the lever connector 90 and the bearing support portion 83 of the bearing support member 80.

[0091] In addition, such as Figure 6 As shown, in order to cooperate with the above-mentioned connector 60, the lever 30 also has a third internal threaded hole 37 that axially communicates with the pivot hole 33 and an inner flange 36 that protrudes inward from the periphery of the third internal threaded hole 37.

[0092] During assembly, first use a tool (e.g., a hex wrench, not shown in the figure) to engage the inner polygonal hole 74 of the retaining ring connector 70 and apply force to rotate it, so that the external threaded shaft 71 of the retaining ring connector 70 is screwed into the first internal threaded hole 15 of the retaining ring 10. Then use another tool (e.g., a hex wrench, not shown in the figure) to engage the inner polygonal hole 94 of the lever connector 90 and apply force to rotate it, so that the external threaded part 93 of the lever connector 90 is screwed into the third internal threaded hole 37 of the lever 30. Continue until the lever connector 90 is locked so that the inner ring 41 simultaneously abuts against the outer flange 91 of the lever connector 90 and the inner flange 36 of the lever 30, and the outer ring 42 abuts against the inner flange 84 of the bearing support 80 and the disc part 73 of the retaining ring connector 70. This completes the assembly of the retaining ring 10, connector 60, lever 30 and bearing 40. Next, another tool (such as a screwdriver, not shown) is engaged with the adjusting screw 50 through the inner polygonal hole 94 of the lever connector 90 and rotated. This causes the adjusting screw 50 to push against the pushed portion 56 of the positioning block 52. As a result, the positioning portion 54 of the positioning block 52 will press against the handlebar 2 that passes through the cable tie 12, thus fixing the cable tie 10 and the handlebar 2 together. Conversely, when the adjusting screw 50 releases the pushed portion 56 of the positioning block 52, the positioning portion 54 of the positioning block 52 also releases the handlebar 2, allowing the cable tie 10 to be adjusted in position or removed from the handlebar 2.

[0093] As can be seen from the above, in the second embodiment of the present invention, the cable control device 1' uses the connector 60 to assemble the cable loop 10 and the lever 30 together and position the installation angle of the lever 30. Then, the adjusting screw 50 is used to tighten the cable loop to the handlebar 2. The two will not affect each other, and the installation angle of the lever 30 will not be affected by loosening the adjusting screw 50. In this way, the purpose of increasing the convenience of operation can be achieved.
