Description

Brake cable fastening device of bicycle and bicycle comprising same

Technical Field

Embodiments of the present disclosure relate generally to the field of bicycles, and more particularly, to a brake cable fastening device of a bicycle and a bicycle including the same.

Background

The brake device of a bicycle typically drives a brake member of the brake device into frictional contact with a portion of the wheel (e.g., a rim or axle) via a brake cable to stop the wheel from rotating. In order to achieve the actuation of the brake member in the brake device by the brake cable, it is generally necessary to fasten the brake cable to a member capable of actuating the brake member in the brake device.

The existing brake cable fastening device fixes the brake cable at one end of the brake cable adjusting bolt. In such a brake cable fastening device, undesired movement of the adjusting bolt is liable to occur, resulting in loosening of the brake cable. Such a situation may cause the brake cable to become slack, thereby affecting normal braking action.

Detailed Description

The present disclosure will now be described with reference to several example embodiments. It should be understood that these examples are described only for the purpose of enabling those skilled in the art to better understand and thereby enable the present disclosure, and are not intended to set forth any limitations on the scope of the technical solutions of the present disclosure.

As used herein, the term "include" and its variants are to be read as open-ended terms meaning "including, but not limited to. The term "based on" will be read as "based at least in part on". The terms "one embodiment" and "an embodiment" should be understood as "at least one embodiment". The term "another embodiment" should be understood as "at least one other embodiment". The terms "first," "second," and the like may refer to different or the same object. Other explicit and implicit definitions may be included below. The definitions of the terms are consistent throughout the specification unless the context clearly dictates otherwise.

As already briefly mentioned above, the inventor has noticed that in the braking devices of the prior art bicycles, one end of the brake cable is connected to a member (for example, the handle of the brake) operable by the user, and the other end is fixed to one end of the brake cable adjusting bolt. In such a brake cable fastening device, undesired movement of the adjusting bolt is liable to occur, resulting in loosening of the brake cable. Such a situation may cause the brake cable to become slack, thereby affecting normal braking action. The problems are particularly prominent in shared bicycles with high use frequency and high maintenance difficulty. Failures due to loosening of the adjusting nut often result in the shared bicycle not being able to continue to be used. This problem presents a great difficulty in the operation and maintenance of the shared bicycle.

Based on the above recognition, there is provided a brake cable fastening device for a bicycle and a bicycle including the same, which can effectively overcome the above problems. Generally, the brake cable fastening device of the bicycle forms a fastening part using a fastening bolt and a fastening nut, passes a brake cable through a through hole of the fastening bolt, and clamps and fixes the brake cable using a clamping force between the fastening bolt and a brake lever. In this way, the brake cable fastening device of the bicycle according to the embodiments of the present disclosure makes the fastening of the brake cable more reliable, thereby improving the stability and reliability of the bicycle in use. Accordingly, embodiments of the present disclosure can effectively solve the above-described problems. Some example embodiments of the present disclosure will be described in detail below with reference to fig. 1 to 6.

As shown in fig. 1 and 2, the brake cable W of the bicycle is connected to the brake device 20 through the brake cable fastening device 1. It should be appreciated that the brake apparatus 20 may be implemented in various suitable forms. For example, the brake device 20 may be a drum brake device. In this respect, the present disclosure is not particularly limited. In such an arrangement, a user can actuate the brake cable by operating a component such as a brake lever, which in turn actuates the brake device 20 through the brake cable securing device 1 to effect a braking action.

The brake cable fastening device 1 comprises a brake swing rod 10. The brake swing lever 10 has a first end 11 and a second end 12 opposite in a longitudinal direction. A connecting hole 13 is arranged at the first end 11 of the brake swing rod 10. The brake lever 10 can be coupled to the brake apparatus 20 through the coupling hole 13. For example, as shown in fig. 1, the connection hole 13 may be a square hole. The brake device 20 may be provided with a coupling post 21 that mates with the inner contour of the coupling hole 13. The coupling hole 13 is sleeved on the coupling post 21 and fastened with a nut 22. In this way, the swing of the brake lever 10 can drive a brake member (not shown) in the brake device 20 to be in frictional contact with a portion of the wheel (e.g., a rim or a wheel axle) through the connecting column 21, thereby stopping the rotation of the wheel. In addition, a positioning hole 14 for fixing the fastening bolt 30 is provided adjacent to the second end 12 of the brake swing lever 10.

The brake cable fastening device 1 further includes a fastening bolt 30 and a fastening nut 31. The fastening bolt 30 and the fastening nut 31 are fixed at the positioning hole 14 by screw engagement. Specifically, the fastening bolt 30 includes a bolt head 32. In fig. 1, the bolt head 32 is schematically shown as being circular. It should be understood that the bolt head 32 may be implemented in a variety of suitable forms. As shown in fig. 1, the bolt head 32 is disposed on one side 15 (also referred to herein as a "first side") of the brake swing lever 10. In fig. 1, the first side 15 is schematically shown as the side facing the brake device 20. It should be understood that in different embodiments, the first side 15 may also be the side facing away from the brake device 20. In this respect, the present disclosure is not particularly limited. The bolt head 32 has a clamping surface 321 facing the first side 15 of the brake swing link 10. In the assembled state of the brake cable fastening device 1 with the brake cable W, a portion of the brake cable W will be clamped between the clamping surface 321 and the first side 15 of the brake lever 10, thereby achieving fastening of the brake cable W.

The fastening bolt 30 further includes a through hole 33 (also referred to herein as a "first through hole"). The through hole 33 may penetrate the fastening bolt 30 in a direction intersecting with the longitudinal axis X of the fastening bolt 30 (e.g., a direction perpendicular to the longitudinal axis X). In the assembled state of the brake cable fastening device 1 with the brake cable W, the brake cable W will pass through the through hole 33, and thus be clamped on both sides of the through hole 33.

The fastening bolt 30 also includes a threaded portion 34. One portion of the threaded portion 34 is disposed in the positioning hole 14 and the other portion protrudes from the positioning hole 14 to achieve threaded engagement with the fastening nut 31.

The fastening nut 31 is disposed on a side 16 (also referred to herein as a "second side") of the brake lever 10 opposite the first side 15. In fig. 1, the second side 16 is schematically shown as the side facing away from the brake device 20. It should be understood that the second side 16 may be the side facing the brake device 20 in various embodiments. In this respect, the present disclosure is not particularly limited. The fastening nut 31 is engaged with the threaded portion 34 to fix the fastening bolt 30 at the positioning hole 14.

As can be seen, in the brake cable fastening device 1 according to the embodiment of the present disclosure, the brake cable W passes through the through-hole 33 and is clamped between the bolt head 32 and the brake lever 10 at both sides of the through-hole 33, thereby effectively preventing the loosening of the brake cable W. Therefore, the brake cable fastening device 1 according to the embodiment of the present disclosure is more reliable, thereby improving stability and reliability of bicycle use.

In some embodiments, for example as shown in fig. 1 to 4, the brake cable fastening device 1 according to embodiments of the present disclosure may further include a housing 40 for covering the fastening bolt 30, the fastening nut 31, and a portion of the brake cable W. The housing 40 may be secured adjacent the second end 12 of the brake swing lever 10. The case 40 may include a case main body 41 and a cover plate 42.

The case body 41 may include a bottom plate 410 and first and second sidewalls 411 and 412 extending from the bottom plate 410 toward the cover plate 42. For example, as shown in fig. 1 to 4, the first sidewall 411 and the second sidewall 412 may be oppositely disposed. In such an arrangement, the case body 41 may further include a third sidewall 413 and a fourth sidewall 414. The third and fourth sidewalls 413 and 414 are connected between the first and second sidewalls 411 and 412. In such an arrangement, the housing 40 provides shielding for the fastening bolt 30, the fastening nut 31 and the brake cable W, so that these components can be prevented from being contaminated or corroded by dust, rainwater or the like in the external environment, and the service life of the relevant components is prolonged.

In order to facilitate the entry and/or exit of the brake cable W into the housing 40 and/or out of the housing 40, the housing body 41 may be provided with openings. For example, the first side wall 411 may be provided with a first opening 411-1 adapted for passing the brake cable W. Through the first opening 411-1, a brake cable W extending from a component such as a brake lever can enter the housing 40. In such an arrangement, the free end F of the brake cable W may enter the housing 40 from the first opening 411-1 and be hidden within the housing 40, thereby preventing the free end F of the brake cable W from being exposed to the outside.

Further, the second sidewall 412 may be provided with a second opening 412-1 and a third opening 412-2 adapted for passing the brake cable W therethrough. The brake cable W can pass out of the housing 40 through the second opening 412-1. Further, the brake cable W may also be guided into the housing 40 again through the third opening 412-2. In this way, the free end F of the brake cable W can penetrate out of the second opening 412-1 and then enter the housing 40 through the third opening 412-2, so that the free end F of the brake cable W is hidden in the housing 40, and the free end F of the brake cable W is prevented from being exposed to the outside and being scraped to a user, a wheel and the like to cause an accident.

In addition, the housing body 41 may further include a positioning structure 415. By means of the positioning structure 415, the free end F of the brake cable W can be reliably positioned within the housing 40. The positioning structure 415 may include various suitable forms such as a positioning plate, a positioning slot, a positioning post, and the like. For example, referring to fig. 3 and 4, the positioning structure 415 is formed as a positioning plate disposed adjacent to the third opening 412-2.

As shown in fig. 3 and 4, the third sidewall 413 of the case main body 41 may be provided with an opening 413-1. The brake swing link 10 may pass through the opening 413-1 in a state where the housing 40 is fixed near the second end 12 of the brake swing link 10.

In some embodiments, for example, referring to fig. 3, the cover plate 42 may include a tab 422 (also referred to herein as a "first tab") projecting from an edge of the cover plate body 421 toward the case main body 41. In the assembled state of the case main body 41 and the cover plate 42, the first tab 422 may protrude into the second opening 412-1. In this way, the first tab 422 may clamp the brake cable W in the second opening 412-1 in a state where the brake cable W is accommodated in the case 40. Alternatively or additionally, the cover plate 42 may further include a tab 423 (also referred to herein as a "second tab") projecting from an edge of the cover plate body 421 toward the case main body 41. The second tab 423 may protrude into the third opening 412-2 in a state where the case main body 41 and the cover plate 42 are assembled. In this way, the second tab 423 may clamp the brake cable W in the third opening 412-2 in a state where the brake cable W is accommodated in the case 40.

It should be understood that the cover plate 42 may be provided with only one of the first tab 422 and the second tab 423, or may be provided with both the first tab 422 and the second tab 423. The first tab 422 and the second tab 423 are shaped and sized to protrude into the respective second opening 412-1 and third opening 412-2. Furthermore, the first tab 422 and the second tab 423 are shaped and dimensioned to clamp the brake cable W. In this way, on the one hand, the fixation of the brake cable W is achieved, and on the other hand, dust or rain water or the like in the external environment is prevented from entering the interior of the housing 40 from the second opening 412-1 and the third opening 412-2.

Further, as shown in fig. 1 and 3, a protruding portion 424 protruding to the outside of the case 40 may be provided on the cover body 421 of the cover 42. Accordingly, on a side of the cover body 421 facing the inside of the case 40, a concave cavity is formed. As shown in fig. 4, a fastening nut 31 may be received in the recessed cavity.

It should be appreciated that the housing 40 may be secured adjacent the second end 12 of the brake swing lever 10 in a variety of suitable manners. For example, as shown in fig. 3 and 4, a hole 425 through which a screw S passes may be provided on the cover body 421 of the cover 42. Accordingly, on the bottom plate 410 of the case main body 41, positioning posts 416 extending toward the cover plate 42 may be provided. The positioning post 416 is provided with an internal thread for engagement with the screw S. Correspondingly, the brake swing link 10 may be provided with a hole 17 or a groove 18 for the positioning column 416 to pass through. In this manner, the screw S may be sequentially inserted through the hole 425 of the cover plate body 421 and the hole 17 or the groove 18 of the brake swing link 10 to engage with the internal thread of the positioning post 416, thereby achieving the connection of the housing main body 41 and the cover plate 42 and fixing the housing 40 near the second end 12 of the brake swing link 10. The above-described structure is merely one example of the manner of attachment and fixation of the housing 40. In this respect, the present disclosure is not particularly limited.

In various embodiments, the housing body 41 and the cover plate 42 of the housing 40 may be made from various suitable materials and processes. For example, the case main body 41 and the cover plate 42 of the case 40 may be made of plastic molding. In this manner, various features and structures provided on the case main body 41 and the cover plate 42 can be easily obtained.

In assembling the brake cable fastening device 1 according to the embodiment of the present disclosure, the brake cable W first needs to be passed through the first through hole 33 of the fastening bolt 30. After that, the fastening bolt 30 is inserted into the positioning hole 14 so that the threaded portion 34 protrudes from the positioning hole 14. The portion of the threaded portion 34 outside the positioning hole 14 and the fastening nut 31 are then screwed together. As the fastening nut 31 is tightened, the clamping surface 321 of the bolt head 32 gradually approaches the first side 15 of the brake lever 10 and eventually clamps a portion of the brake cable W between the clamping surface 321 and the first side 15 of the brake lever 10.

It is desirable during the above-described assembly that the brake cable W passing through the first through hole 33 of the fastening bolt 30 does not move during the above-described tightening due to the fastening bolt 30 rotating about its longitudinal axis X. That is, it is desirable that the angle between the brake cable W and the brake lever 10 is maintained constant. To this end, a structure that restricts rotation of the fastening bolt 30 about its longitudinal axis X may be provided between the fastening bolt 30 and the positioning hole 14. Herein, the rotation restricting structure on the fastening bolt 30 may be referred to as a "first rotation restricting structure". Accordingly, the rotation restricting structure at the positioning hole 14 may be referred to as a "second rotation restricting structure". The first rotation restricting structure and the second rotation restricting structure are provided to cooperate with each other so as to restrict the fastening bolt 30 from rotating about its longitudinal axis X in a state where the fastening bolt 30 is fixed at the positioning hole 14 (i.e., in a state where the fastening bolt 30 is inserted into the positioning hole 14).

In various embodiments, the above-described rotation restricting structure may be implemented in various suitable forms. For example, the portion of the fastening bolt 30 located in the positioning hole 14 may be provided with a projection or a groove in the radial direction. Accordingly, a groove or a protrusion may be provided in the positioning hole 14 to match the protrusion or the groove. In this way, the fastening bolt 30 is restricted to being axially movable only in the positioning bore 14 and not rotatable about its longitudinal axis X.

Further, the above-described rotation restricting structure may also be realized by a specific sectional profile. As shown, for example, in fig. 3, 5 and 6, the fastening bolt 30 may include a transition portion 35 between the bolt head 32 and the threaded portion 34. The first through hole 33 may be provided in the transition portion 35. In such an arrangement, the first rotation limiting structure comprises at least one straight section of the cross-sectional profile of the transition 35 perpendicular to the longitudinal axis X of the fastening bolt 30. For example, straight portions 351 and 352 in fig. 6. Accordingly, the inner contour of the positioning hole 14 also includes at least one linear portion. For example, straight portions 141 and 142 in fig. 6. In such an arrangement, at least a portion of the transition 35 may be located in the locating hole 14, as shown, for example, in fig. 5. In this way, the rectilinear portion of the cross-sectional profile of the transition portion 35 cooperates with the rectilinear portion of the inner profile of the positioning hole 14, limiting the rotation of the fastening bolt 30 about the longitudinal axis X.

As an example of the cross-sectional profile of the transition portion 35, for example, as shown in fig. 6, the cross-sectional profile of the transition portion 35 may include a first straight portion 351 and a second straight portion 352 parallel to the first straight portion 351. First and second linear portions 351 and 352 are connected to each other by first and second arc portions 353 and 354. Accordingly, the inner contour of the positioning hole 14 may include a first straight portion 141 and a second straight portion 142 parallel to the first straight portion 141. The first straight section 141 and the second straight section 142 are connected to each other by a first arc section 143 and a second arc section 144. The cross-sectional profile of the transition portion 35 matches the inner profile of the locating hole 14. In this way, the transition portion 35 cooperates with the positioning hole 14 through the two planar portions, so that the fastening bolt 30 can be effectively prevented from rotating about its longitudinal axis X.

It should be understood that the rotation restricting structure according to the embodiment of the present disclosure is not limited to the above-listed form. Various structures capable of restricting the rotation of the fastening bolt 30 about its longitudinal axis X are within the scope of the present disclosure.

Furthermore, in some embodiments, for example as shown in fig. 1 and 2, the brake cable fastening device 1 according to embodiments of the present disclosure may further include an adjusting nut 50 for adjusting the tension degree of the brake cable W. The adjusting nut 50 may be disposed at a position farther from the free end F of the brake cable W with respect to the fastening bolt 30 along the course of the brake cable W. The adjusting nut 50 includes a through hole 51 (also referred to herein as a "second through hole") through which the brake cable W can pass. The adjustment nut 50 may also include an adjustment threaded portion 52 having external threads. The adjustment nut 50 may be threadably engaged to the brake device 20 by adjusting the threaded portion 52. For example, the adjusting screw portion 52 may engage a threaded hole (not shown) in the leg 23 of the brake device 20. In this way, the user can adjust the degree of tension of the brake cable W by rotating the adjustment nut 50. It should be understood that in the brake cable fastening device 1 according to the embodiment of the present disclosure, the above-described component for adjusting the degree of tension of the brake cable W is not a necessary component. In the case where the brake wire W has been adapted without adjusting the degree of tension, the above-mentioned components may not be provided.

In some embodiments, such as shown in fig. 1 and 2, the brake cable fastening device 1 according to embodiments of the present disclosure may further include a brake cable protective sleeve 60. For example, the brake cable protective sleeve 60 may be disposed between the leg 23 and the housing 40.

As is apparent from the above description, the brake cable fastening device 1 of the bicycle according to the embodiment of the present disclosure fastens the brake cable W using the clamping force between the clamping surface 321 of the bolt head 32 and the brake lever 10, so that the loosening of the brake cable W can be effectively prevented. Therefore, the brake cable fastening device 1 according to the embodiment of the present disclosure is more reliable, thereby improving stability and reliability of bicycle use.

In addition, the embodiment of the disclosure also provides a bicycle comprising the brake cable fastening device. As can be seen from the above description, since the brake cable fastening device of the bicycle according to the embodiments of the present disclosure is particularly suitable for applications where use is frequent and maintenance is inconvenient, applying the brake cable fastening device of the bicycle according to the embodiments of the present disclosure to a shared bicycle can greatly reduce the failure rate of the shared bicycle, thereby providing great convenience to the operation and maintenance of the shared bicycle.

It is to be understood that the above detailed embodiments of the disclosure are merely illustrative of or explaining the principles of the disclosure and are not limiting of the disclosure. Therefore, any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention. Also, it is intended that the following claims cover all such changes and modifications that fall within the scope and boundaries of the claims or the equivalents of the scope and boundaries.
