Description

Technical Field

[0001] The utility model relates to the technical field of bicycle brakes, in particular to an engaging type parking mechanism and a brake handle. Background Art

[0002] Two-wheeled bicycles are generally parked with a diagonal brace, which involves installing a flip-up diagonal brace bracket on one side of the rear half of the frame. However, since the length of the diagonal brace is fixed, it is unstable when parked with a diagonal brace on a terrain with a large slope, and the vehicle is prone to falling and causing injuries.

[0003] Currently, there are meshing parking mechanisms on the market that lock the tires by squeezing the brake lever. However, these mechanisms typically only offer a single-stage locking force, making them incapable of adapting to the braking forces required on slopes of varying inclinations. This can lead to unstable parking on steeply sloped terrain. To address this issue, we propose a meshing parking mechanism and brake lever. Utility Model Content

[0004] The present application provides an engaging parking mechanism and a brake handle to at least solve the problem in the prior art that the engaging parking mechanism only has a locking function of a single fixed force, cannot adapt to the braking force required for slopes of different slopes, has large parking force deviation, and is unstable.

[0005] In a first aspect, the present application provides an engaging parking mechanism, comprising a base and a brake handle rotatably mounted on the base via a rotating pin, wherein the base is provided with a parking member for locking the brake handle in a braking position, the parking member comprising:

[0006] An engaging tooth portion integrally formed at a lower end portion of the brake handle near the rotating pin;

[0007] A parking dial, wherein a rotating shaft is fixedly passed through the middle thereof, and the rotating shaft is rotatably assembled with the base, and the annular outer wall of the parking dial is integrally formed with: a parking latch tooth portion that cooperates with the meshing tooth portion to position and engage with the meshing tooth portion to prevent the brake handle from reversing, and a rotation-stop key portion that is provided on the opposite side of the parking latch tooth portion and cooperates with a base positioning surface to limit the rotational travel of the parking dial in the parking state, wherein the base positioning surface is provided at an assembly position of the base close to the brake handle;

[0008] A parking lever, which is fixedly sleeved on one end of the rotating shaft and rotatably assembled with the outer side of the base;

[0009] An elastic member is located in the parking lever and is positioned and sleeved on the rotating shaft.

[0010] Optionally, the parking member further includes:

[0011] A rotation slot is provided on the outer side wall of the base corresponding to the position of the parking lever, and has an in-position prompt slot provided therein;

[0012] There is at least one positioning protrusion, which is provided on a side of the parking lever facing the base;

[0013] The positioning protrusion cooperates with the wavy groove to produce a jerking feeling on the parking lever, indicating that the parking stroke is in place.

[0014] Optionally, the in-place prompt groove is in a cross shape, and there are two in-place protrusions symmetrically distributed in the in-place prompt groove.

[0015] Optionally, the meshing tooth portion is a split structure, which is embedded in a preset groove opened at the end of the brake handle and is positioned and assembled by the rotating pin.

Those skilled in the art will understand the specific meanings of the above terms in this utility model based on the specific circumstances.

[0034] In the related art, there is currently an engaging parking mechanism on the market that locks the position after the brake handle is squeezed to lock the tire. However, since it generally only has a locking function with a single fixed force, it cannot adapt to the braking force required for slopes of different slopes, which leads to unstable parking on the aforementioned terrain with a large slope.

[0035] Based on the above situation, an embodiment of the present invention provides an engaging parking mechanism and a brake handle, which are described in detail below with reference to specific embodiments and drawings.

[0036] Example 1

[0037] An embodiment of the utility model provides an engaging parking mechanism. Figure 1 is a perspective view of a brake handle with an engaged parking mechanism according to an exemplary embodiment. Figure 2 FIG. 1 is an exploded view of a structure having an engaged parking mechanism according to an exemplary embodiment. Figure 3 is a cross-sectional view of a brake handle with an engaged parking mechanism according to an exemplary embodiment. Figure 4 It is a schematic diagram of the three-dimensional structure of a meshing parking mechanism according to an exemplary embodiment. Figure 5 FIG. 1 is an exploded view of the structure of a meshing parking mechanism according to an exemplary embodiment. Figure 1-5 As shown, the engaging parking mechanism includes a base 10 and a brake handle 30 rotatably mounted on the base 10 via a rotating pin 20. The base 10 is provided with a parking member 40 for locking the brake handle 30 in a braking position. The parking member 40 includes:

[0038] The meshing tooth portion 401 is integrally formed at the lower end of the brake handle 30 near the rotating pin 20;

[0039] The parking dial 402 has a rotating shaft 403 fixedly extending through its center and rotatably assembled with the base 10. The parking dial 402 has integrally formed on its annular outer wall: a parking latch portion 4021 that engages with the meshing tooth portion 401 to prevent reverse rotation of the brake lever 30; and a rotation-stopping key portion 4022 disposed opposite the parking latch portion 4021 and engaging a base positioning surface 409 to limit the rotational travel of the parking dial 402 in the parking state. The base positioning surface 409 is disposed at a position on the base 10 near the assembly of the brake lever 30.

[0040] The parking lever 405 is fixedly mounted on one end of the rotating shaft 403 and is rotatably assembled with the outer side of the base 10;

[0041] The elastic member 404 is located in the parking lever 405 and is positioned and sleeved on the rotating shaft 403. In this embodiment, the elastic member 404 is a tension spring.

[0042] In the technical solution of the above embodiment, Figure 6 1 is a schematic diagram of a non-parking state of an engaged parking mechanism according to an exemplary embodiment. Figure 7 FIG. 1 is a schematic diagram showing a parking state of an engaged parking mechanism according to an exemplary embodiment. Figure 1-7 , when not in parking state Figure 6 As shown, the parking lever 406 is at the 11 o'clock position of the rotation starting point. At this time, the parking tooth portion 4021 does not interfere with the rotation stroke of the meshing tooth portion 401. When parking is required, refer to the attached Figure 7 , the parking lever 406 is turned counterclockwise to the 8-9 o'clock position. At this time, the parking tooth portion 4021 and the stop key portion 4022 on the parking dial 402 both change angles at the same time, flipping to the parking state. The stop key portion 4022 contacts the base positioning surface 409, limiting the rotational travel of the parking dial 402;

[0043] When the rider squeezes the brake lever 30 to brake the front / rear wheels of the bicycle, the brake lever 30 rotates along the rotating pin 20. At this time, the meshing tooth portion 401 rotates counterclockwise until it gradually meshes with the parking latch tooth portion 4021 to form a toothed positioning, achieving a stable anti-return effect on the brake lever 30 and preventing it from easily disengaging. The rider continues to squeeze the brake lever 30 counterclockwise until the meshing tooth portion 401 rotates to a position that can provide the required parking force. This adapts the brake lever 30 to the parking force required under the current terrain conditions or position, achieves rapid adaptive parking, and effectively optimizes the parking effect of the bicycle under different conditions.

[0044] It is understandable that, with reference to the Figure 5-6When the parking position needs to be released, the parking lever 406 is turned clockwise, and the parking lever 406 drives the parking dial wheel 402 to rotate clockwise to the non-parking state position, the parking gear portion 4021 disengages the meshing gear portion 401, and the brake handle 30 automatically returns to its original position elastically without restriction in conjunction with oil pressure or cable pull, and the bicycle can be ridden freely.

[0045] Further, in this embodiment, continue to refer to the attached Figure 2 The parking member 40 further includes:

[0046] A rotation slot 407 is formed on the outer wall of the base 10 at a position corresponding to the parking lever 405 and has an in-position indication slot 408 formed therein;

[0047] There is at least one positioning protrusion 406 , which is provided on the side of the parking lever 405 facing the base 10 ;

[0048] The in-position protrusion 406 cooperates with the wavy groove 408 to produce a sense of frustration on the parking lever 405, indicating that the parking range is in place. In this embodiment, the in-position prompting groove 408 is in a cross shape, and there are two in-position protrusions 406 symmetrically distributed in the in-position prompting groove 408;

[0049] In the technical solution of the above embodiment, continue to refer to the attached Figure 2 When the parking lever 406 is moved to the travel position in the non-parking state and the parking state, that is, when the in-position protrusion 406 rotates to the two grooves of the in-position prompt groove 408 respectively, the in-position protrusion 406 cooperates with the elastic tension of the elastic member 404 to produce an obvious pressing and stopping feeling, prompting the rider that the vehicle has been parked.

[0050] Continue to refer to the attached Figure 4-5 The meshing tooth portion 401 is a split structure, which is embedded in a preset groove opened at the end of the brake handle 30 and is positioned and assembled by the rotating pin 20, reducing production difficulty and facilitating large-scale processing and production.

[0051] In summary, the meshing parking mechanism provided by the embodiment of the present invention cooperates with the meshing teeth 401, the parking dial wheel 402 and the parking lever 406. When parking is required, the parking lever 406 can be adjusted to the parking position. When the rider squeezes the brake lever 30 to brake the front / rear wheels of the bicycle, the brake lever 10 rotates along the rotating pin 20, and the meshing teeth 401 rotates to gradually mesh with the parking tooth portion 4021 on the parking dial wheel 402. The meshing parking can stably prevent the brake lever 10 from being reset and will not be easily disengaged. Continue to squeeze the brake lever 30 counterclockwise until the meshing teeth 401 rotates to the position where the parking force is required, and then the brake lever 30 can be adapted to the parking force required under the current terrain conditions or position, and the parking is quickly adaptive, which effectively optimizes the parking effect of the bicycle under different conditions.

[0052] Example 2

[0053] This embodiment 2 provides a brake handle. Figure 1-3 , including the meshing parking mechanism of the first aspect mentioned above.

[0054] Optionally, a tie lock 101 is integrally formed on the lower portion of the base 10 , and the tie lock 101 is detachably fixed to the handlebar of the bicycle with the help of fastening bolts.

[0055] In summary, the meshing parking mechanism and brake handle provided by the embodiment of the present invention cooperate with the meshing teeth 401, the parking dial wheel 402 and the parking lever 406. When parking is required, the parking lever 406 can be adjusted to the parking position. When the rider squeezes the brake lever 30 to brake the front / rear wheels of the bicycle, the brake lever 10 rotates along the rotating pin 20, and the meshing teeth 401 rotates to gradually mesh with the parking tooth portion 4021 on the parking dial wheel 402. The meshing parking can stably prevent the brake lever 10 from being reset and will not be easily disengaged. Continue to squeeze the brake lever 30 counterclockwise until the meshing teeth 401 rotates to the position where the parking force is required, and then the brake lever 30 can be adapted to the parking force required under the current terrain conditions or position, and the parking is quickly adaptive, which effectively optimizes the parking effect of the bicycle under different conditions.
