Description

Technical Field

[0001] The utility model belongs to the technical field of vehicle braking, and in particular relates to a parking mechanism and a riding vehicle. Background Art

[0002] Existing vehicles (two-wheeled, three-wheeled electric bicycles or motorcycles) usually use hydraulic brake devices to brake. In order to ensure that the vehicle is in a stationary state under conditions such as inclined roads, it is necessary to set a parking mechanism to prevent the vehicle from slipping and causing accidents.

[0003] Most of the existing parking mechanisms cannot or are difficult to achieve single-handed operation. For example, a Chinese patent with a parking mechanism disclosed in the publication number CN2835070Y has a brake lever consisting of a parking boss and a rocker arm. The brake handle is fixed on a handle fixing seat and can rotate around the handle fixing seat. The handle fixing seat is provided with a groove on the end surface opposite to the front end of the brake handle. The parking boss is located in the groove and fixed on the handle fixing seat and can rotate around the handle fixing seat. A rocker arm is provided at the upper end of the parking boss. The end surface of the front end of the brake handle facing the parking boss is serrated. When in use, the brake handle is tightly squeezed by hand, and the brake handle drives the brake cable to stop the vehicle. At the same time, the rocker arm needs to be pulled by the other hand so that the parking boss connected to the rocker arm is tightly stuck in the concave teeth of the brake handle to achieve parking. The parking structure requires two hands to operate at the same time, and parking cannot be completed with one hand, which is inconvenient to use.

[0004] In order to solve the one-hand operation problem, CN218839413U, CN219406783U, CN219345468U, etc. all disclose one-hand operation schemes. However, the parking mechanisms of the above one-hand operation schemes have more or less the following problems: 1. The finger-operated parts are located near the rotating shaft of the brake handle, and the index finger (or thumb pressing) is required to operate when parking, which is not convenient; 2. The locking part may rotate when parking, and the parking may fail; 3. The ratchet mechanism is in a meshing state when releasing the parking, which is difficult to release. Utility Model Content

[0005] The utility model aims to solve the problems of inconvenient operation, unreliable parking or difficult release of parking in existing vehicle parking mechanisms, and provides a parking mechanism to improve at least one of the following: improved operation convenience, improved parking reliability and easier release of parking. The utility model also provides a riding vehicle using the parking mechanism.

[0006] To achieve the above object, the utility model adopts the following technical solution: a parking mechanism is installed on a brake mechanism, the brake mechanism includes a main pump body and a brake handle assembly swingably connected to the main pump body, and the parking mechanism includes:

[0007] The locking block swings along with the brake handle assembly to form a first locking portion;

[0008] The locking tongue is movably disposed in the main pump body and is farther away from the brake handle assembly than the locking block to form a second locking portion;

[0009] Finger-shift, swing-connected to the main pump body;

[0010] A linkage component connects the finger shifter and the lock tongue so that the finger shifter and the lock tongue are linked;

[0011] A positioning component for positioning the position of the finger shifter;

[0012] When the brake handle assembly is in the braking position and the lock tongue is in the locking position, the second locking portion of the lock tongue cooperates with the first locking portion of the lock block to prevent the brake handle assembly from resetting. At this time, the positioning assembly positions the position of the finger shifter.

[0013] The parking mechanism of the utility model comprises a lock block, a lock tongue, a finger shifter, a linkage assembly and a positioning assembly. The lock block swings with the brake handle assembly, the lock tongue and the finger shifter are linked by the linkage assembly, and the positioning assembly at least positions the finger shifter in the locked position. When the brake handle assembly is in the brake position and the lock tongue is in the locked position, the second locking portion of the lock tongue cooperates with the first locking portion of the lock block to prevent the brake handle assembly from resetting. At this time, the positioning assembly positions the position of the finger shifter. When it is necessary to release the parking, the finger shifter is reversely dialed to release the positioning of the finger shifter by the positioning assembly, so that the lock tongue rotates from the locked position to the unlocked position. When the lock tongue reaches the unlocked position, the second locking portion of the lock tongue is released from the first locking portion of the lock block, and the brake handle assembly is reset to the unbraked position. When parking, the finger shifter is dialed by the thumb, which is convenient to operate. The positioning assembly at least positions the lock tongue in the locked position, thereby ensuring reliable parking. By dialing the finger shifter by the thumb, it is easy to release the parking lock. The finger shifter can form a lever structure, which is labor-saving.

[0014] As an improvement, the linkage assembly includes an eccentric shaft that swings with the finger shift, a movable part that is linked to the eccentric part of the eccentric shaft, and compression springs acting on both ends of the movable part's moving direction. The lock tongue forms an installation groove, and the movable part and the compression spring are both located in the installation groove.

[0015] As an improvement, a guide groove is formed on the main pump body, the locking tongue is located in the guide groove, and the guide groove guides the locking tongue.

[0016] As an improvement, the first locking portion includes a plurality of first teeth, the second locking portion includes a plurality of second teeth, and the first locking portion and the second locking portion form a ratchet mechanism. The cooperation of the plurality of teeth enables the brake handle assembly to achieve parking in a wide range of positions.

[0017] As an improvement, the force-bearing surface of the second tooth portion is in the reciprocating direction of the lock tongue, so it is easier to release the lock of the lock tongue.

[0018] As an improvement, a circumferential anti-slip groove is formed on the eccentric shaft, an axial anti-slip screw is installed on the main pump body, the inner end of the anti-slip screw is located in the anti-slip groove, and the axial dimension of the inner end of the anti-slip screw is adapted to the axial dimension of the anti-slip groove.

[0019] As an improvement, the eccentric shaft has an anti-rotation portion, and the finger shifter has an anti-rotation groove, and the anti-rotation portion and the anti-rotation groove cooperate to prevent the eccentric shaft and the finger shifter from rotating; the eccentric shaft and the finger shifter are tightly fitted.

[0020] As an improvement, the positioning assembly includes a ball-end screw, and a positioning groove cooperating with the ball-end screw is formed on the main pump body.

[0021] As an improvement, the positioning slot includes an unlocking position positioning slot and a locking position positioning slot; and the ball screw is a bare ball screw.

[0022] A riding vehicle comprises a handlebar tube, a brake mechanism and a parking mechanism. The brake mechanism comprises a main pump body and a brake handle assembly swingably connected to the main pump body. The main pump body is mounted on the handlebar tube. The brake mechanism is the aforementioned parking mechanism.

[0023] The parking mechanism of the utility model has the following beneficial effects: the thumb can be used to move the finger lever when parking, which is convenient to operate; the positioning component can at least position the lock tongue when it is in the locked position, thereby ensuring reliable parking; the index finger can be used to move the finger lever, which makes it easier to release the parking lock.

[0045] The technical solutions of the embodiments of the present invention are explained and described below, but the following embodiments are only preferred embodiments of the present invention, not all. Based on the embodiments in the implementation mode, other embodiments obtained by those skilled in the art without creative work are all within the protection scope of the present invention.

[0046] See also Figures 1 to 13, a riding vehicle, comprising a handlebar tube, a brake mechanism and a parking mechanism 03, wherein the brake mechanism comprises a main pump body 01 and a brake handle assembly 02 swingably connected to the main pump body 01, the main pump body 01 is mounted on the handlebar tube, and the parking mechanism 03 comprises:

[0047] The locking block 1 swings with the brake handle assembly 02 to form a first locking portion 11;

[0048] The locking tongue 2 is movably disposed in the main pump body 01 and is farther away from the brake handle assembly 02 than the locking block 1, forming a second locking portion 21;

[0049] The finger shifter 3 is swingably connected to the main pump body 01;

[0050] The linkage component 4 connects the finger shifter 3 and the lock tongue 2 so that the finger shifter 3 and the lock tongue 2 are linked;

[0051] A positioning component 5 for positioning the finger shifter 3;

[0052] When the brake handle assembly 02 is in the braking position and the lock tongue 2 is in the locking position, the second locking portion 21 of the lock tongue 2 cooperates with the first locking portion 11 of the lock block 1 to prevent the brake handle assembly 02 from resetting. At this time, the positioning assembly 5 positions the position of the finger shifter 3.

[0053] In this embodiment, the brake mechanism includes a main pump body 01, a brake handle assembly 02, a return spring, etc. The return spring generates a force to return the brake handle assembly 02. The structure of the brake mechanism can refer to the drawings and the prior art.

[0054] In this embodiment, the brake handle assembly 02 swings relative to the main pump body 01 , and the shifter 3 swings relative to the main pump body 01 .

[0055] In this embodiment, the locking block 1 is fixed to the brake handle assembly 02 via two pins.

[0056] See also Fig.12 and Fig.13 In this embodiment, the linkage assembly 4 includes an eccentric shaft 41 that swings with the finger shifter 3, a movable member 42 that is linked to the eccentric portion 412 of the eccentric shaft 41, and compression springs 43 that act on both ends of the movable member 42 in the moving direction. The lock tongue 2 forms a mounting groove 22, and the movable member 42 and the compression spring 43 are both located in the mounting groove 22. The mounting groove 22 is rectangular and penetrates the lock tongue 2. The movable member 42 is U-shaped, and the opening of the movable member 42 faces the eccentric shaft 41. The two side walls of the opening of the movable member 42 are distributed along the moving direction of the movable member 42. The eccentric portion 412 of the eccentric shaft 41 is located in the opening of the movable member 42. The radial dimension of the eccentric portion 412 of the eccentric shaft 41 is adapted to the dimension between the two side walls of the opening of the movable member 42.

[0057] In this embodiment, a guide groove is formed on the main pump body 01, and the lock tongue 2 is located in the guide groove. The guide groove guides the lock tongue 2 in a linear manner. The guide groove is a blind groove, and the cross-section of the guide groove perpendicular to its movement direction is oval and adapted to the cross-sectional size of the lock tongue 2.

[0058] In this embodiment, the first locking portion 11 includes a plurality of first teeth, the second locking portion 21 includes a plurality of second teeth, and the first locking portion 11 and the second locking portion 21 form a ratchet mechanism. The cooperation of the plurality of teeth enables the brake handle assembly 02 to achieve parking in a wide range of positions.

[0059] In this embodiment, the lock tongue 2 moves in a straight line, and the force-bearing surface of the second tooth portion is in the reciprocating direction of the lock tongue 2, so it is easier to release the lock of the lock tongue 2.

[0060] In this embodiment, a circumferential anti-slip groove 413 is formed on the eccentric shaft 41, and an axial anti-slip screw 6 is installed on the main pump body 01. The inner end of the anti-slip screw 6 is located in the anti-slip groove 413, and the axial dimension of the inner end of the anti-slip screw 6 is adapted to the axial dimension of the anti-slip groove 413.

[0061] In this embodiment, the eccentric shaft 41 has an anti-rotation portion 411, and the finger shifter 3 has an anti-rotation groove 31. The anti-rotation portion 411 and the anti-rotation groove 31 cooperate to prevent the eccentric shaft 41 and the finger shifter 3 from rotating. The eccentric shaft 41 and the finger shifter 3 are tightly fitted.

[0062] In this embodiment, the positioning assembly 5 includes a ball screw installed on the finger shifter 3, a positioning groove matched with the ball screw is formed on the main pump body 01, and a positioning mounting hole 32 is formed on the finger shifter 3. The positioning groove is a semicircular groove. In other embodiments, the ball screw can also be replaced by a spring and a steel ball, and in this case, the mounting hole of the finger shifter 3 can be reduced to prevent the steel ball from falling off.

[0063] In this embodiment, the positioning groove includes an unlocking position positioning groove and a locking position positioning groove; the ball screw is a bare ball screw, so there is no need to open a through hole on the finger shifter 3, and the ball screw can be installed by opening a blind hole. The ball screw and the through hole can be interference fit, transition fit or clearance fit.

[0064] In this embodiment, when parking is required, the thumb is used to move the finger lever 3, and when parking is required to be released, the index finger is used to move the finger lever 3 in the opposite direction. Indicator marks are formed on the main pump body 01, and the indicator marks include a locking mark, an unlocking mark and a direction mark.

[0065] In this embodiment, the figure shows the parking mechanism 03 used by the left hand.

[0066] In this embodiment, during assembly, the locking tongue 2, two compression springs 43 and the movable part 42 are assembled together in advance, and are inserted into the guide groove in a straight line from the neutral position of the main pump body 01. The dial knob, the eccentric shaft 41 and the positioning assembly 5 are assembled together in advance, the eccentric shaft 41 is aligned with the axial hole on the main pump body 01, and the eccentric part 412 of the eccentric shaft 41 is aligned with the movable part 42. The dial knob, the eccentric shaft 41 and the positioning assembly 5 are installed on the main pump body 01, and then the anti-slip screw 6 is installed from the side. Finally, the lock block 1 and the brake handle assembly 02 are fixed, and the brake handle assembly 02 is installed on the main pump body 01, and the installation of the parking mechanism 03 is completed.

[0067] See also Figures 2 to 5 The working process of the riding vehicle parking in this embodiment is: during normal driving, the state of the vehicle is shown in FIG. Figure 2 and Figure 4 At this time, the eccentric portion 412 of the eccentric shaft 41 of the linkage assembly 4 is located further away from the lock block 1, so that the lock tongue 2 is basically located in the guide groove of the main pump body 01, and the lock block 1 on the brake handle assembly 02 is separated from the lock tongue 2 on the main pump body 01 (even at this time, the brake lock block 1 and the lock tongue 2 will not contact each other), and the angle between the brake handle of the brake handle assembly 02 and the finger shift 3 is approximately 110°, and the position of the shift knob is fixed relative to the main pump body 01 by the positioning assembly 5 (glass bead screw) and the unlocking position positioning groove; when parking is required, the thumb is moved along Figure 2 The finger shifter 3 is turned clockwise to overcome the elastic force of the ball screw, so that the finger shifter 3 rotates approximately 150°. When it is turned in place, the steel ball of the positioning assembly 5 (ball screw) enters the locking position positioning groove of the main pump body 01. During the rotation of the finger shifter 3, the eccentric shaft 41 that rotates with the finger shifter 3 gradually moves toward the lock block 1, and the locking tongue 2 moves toward the lock block 1 through the force transmitted by the compression spring 43 (the locking tongue 2 moves straight under the action of the guide groove). When the finger shifter 3 is turned in place, the brake handle assembly 02 is operated to make the brake handle assembly 02 move along Figure 2 The first locking portion 11 of the lock block 1 gradually contacts the second locking portion 21 during the rotation of the brake handle assembly 02, and the compression spring 43 between the second locking portion 21 and the eccentric portion 412 is intermittently compressed, so that the second locking portion 21 of the lock tongue 2 is finally engaged with the first locking portion 11 of the lock block 1. At this time, the brake handle assembly 02 is released. Since the first locking portion 11 and the second locking portion 21 form a one-way ratchet mechanism, and the position of the eccentric shaft 41 is maintained by the positioning assembly 5 (glass bead screw) and the locking position positioning groove, the position of the lock tongue 2 is also maintained (the compression spring 43 will not be further compressed when no force is received along the movement direction of the lock tongue 2), and the position of the brake handle assembly 02 is maintained, so that the vehicle is kept in the parking state. At this time, the vehicle state is shown Figure 3 and Figure 5 .

[0068] See also Figures 2 to 5The working process of releasing the parking of the riding vehicle in this embodiment is as follows: when the parking needs to be released, Figure 3 and Figure 5 The toggle knob 3 is turned counterclockwise with the index finger to overcome the elastic force of the positioning assembly 5 (glass bead screw) and turn the toggle knob to the unlocking position. When the toggle knob reaches the unlocking position, the position of the toggle knob is maintained under the action of the positioning assembly 5 and the unlocking position positioning groove. In the process of turning the toggle knob, the eccentric shaft 41 rotates with the toggle knob, and the eccentric portion 412 of the eccentric shaft 41 rotates in the direction away from the lock block 1. The eccentric portion 412 of the eccentric shaft 41 transmits the force through the compression spring 43 to move the lock tongue 2 in the direction away from the lock block 1 (the lock tongue 2 moves straight under the action of the guide groove). Since the force-bearing surface of the second locking portion 21 of the lock tongue 2 is consistent with the straight-moving direction of the lock tongue 2, the lock tongue 2 can be moved with a smaller force. When the toggle knob, the linkage assembly 4 and the lock tongue 2 are in place, the brake handle assembly 02 can be reset under the action of the reset spring of the brake mechanism, and the vehicle can enter the riding state. The state of the vehicle during riding can be seen Figure 2 and Figure 4 .

[0069] In this embodiment, the operation of the brake handle assembly 02 and the operation of the dial knob can be in any order during parking, that is, the brake handle assembly 02 can be operated first and then the dial knob, or the dial knob can be operated first and then the brake handle assembly 02. When releasing parking, the dial knob needs to be operated first.

[0070] The beneficial effects of the riding vehicle of the first embodiment of the utility model are as follows: its parking mechanism 03 comprises a locking block 1, a locking tongue 2, a finger shifter 3, a linkage assembly 4, a positioning assembly 5 and an anti-slip screw 6; the locking block 1 swings with the brake handle assembly 02; the locking tongue 2 and the finger shifter 3 are linked by the linkage assembly 4; the positioning assembly 5 at least positions the finger shifter 3 when it is in the locked position; the thumb is used to perform the toggling operation required for parking, and the index finger is used to perform the toggling operation required for releasing the parking, which is convenient to operate; the positioning assembly 5 positions the locking tongue 2 when it is in the locked position, thereby ensuring reliable parking; the thumb is used to perform the toggling operation on the finger shifter 3 when parking, which is convenient for one-handed operation; the finger shifter 3 can form a lever structure, which is more labor-saving; the locking tongue 2 moves in a straight line, and the force-bearing surface of the second locking portion 21 of the locking tongue 2 is consistent with the straight-moving direction of the locking tongue 2, which is more labor-saving when unlocking; the parking mechanism 03 is relatively easy to assemble and assemble to the main pump body 01.
