Description

Technical Field

[0002] When bicycles, electric bikes, scooters, and other vehicles are parked against a wall, the front wheel end face is on the same plane as the frame, but the handlebar axis is at an angle to the front wheel end face, resulting in a large space occupation problem. To address this, a rotatable telescopic stem has been proposed. This stem includes upper and lower stems and a quick-release locking mechanism. The upper stem engages with the handlebars, and the lower stem engages with the head tube of the frame. The upper and lower stems are interlocked, and the upper stem can move up and down relative to the lower stem. The quick-release locking mechanism is used to fasten and release the upper and lower stems. When the quick-release locking mechanism releases the upper and lower stems, the upper stem can rotate relative to the lower stem when it moves to a preset position, thereby rotating the handlebars relative to the head tube to reduce space occupation.

[0003] However, the methods used in related technologies to achieve the rotation of the handlebars and head tube are complex and inconvenient to operate. Utility Model Content

[0041] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0042] According to an embodiment of the present invention, the handlebar 1 steering assembly is rotatably mounted on the frame and includes:

[0043] The first vertical tube 2 is used to cooperate with the handlebar 1. The outer peripheral surface of the first vertical tube 2 is provided with a plurality of grooves 21 extending along the axial direction of the first vertical tube 2. The plurality of grooves 21 are arranged at intervals along the circumference of the first vertical tube 2.

[0044] The clamping component 3 includes a clamping body 31 and a quick-release component 32. The lower end of the first vertical tube 2 is at least partially fitted inside the clamping body 31. The quick-release component 32 is connected to the clamping body 31 for fixing and releasing the first vertical tube 2 and the clamping body 31. When the quick-release component 32 releases the first vertical tube 2 and the clamping body 31, the first vertical tube 2 can move up and down and rotate relative to the clamping body 31.

[0045] The elastic component 4 is disposed inside the clamping body 31. One end of the elastic component 4 abuts against the outer peripheral surface of the first vertical tube 2, and one end of the elastic component 4 can be correspondingly fitted into the groove 21.

[0046] Specifically, such as Figures 1 to 6As shown, the upper end of the first vertical tube 2 is connected to the handlebar 1. The first vertical tube 2 extends in the vertical direction, and the lower end of the first vertical tube 2 is at least partially fitted into the clamping body 31. For example, the first vertical tube 2 passes through the clamping body 31 in the vertical direction. The upper half of the clamping body 31 fits into the first vertical tube 2. For example, the inner wall surface of the through hole 311 in the upper half of the clamping body 31 contacts the outer surface of the first vertical tube 2. The first vertical tube 2 can rotate and move up and down relative to the clamping body 31. The quick-release component 32 is used to press and fix the clamping body 31 and the first vertical tube 2 or to unlock and allow rotation and up and down movement.

[0047] The elastic component 4 is disposed inside the clamping body 31 and abuts against the outer peripheral surface of the first vertical tube 2. One end of the elastic component 4 can extend into the groove 21. When the elastic component 4 extends into the groove 21, the elastic component 4 has an initial fixing effect on the first vertical tube 2. It is necessary for the person to rotate the first vertical tube 2 to rotate it relative to the clamping body 31, thereby allowing the elastic component 4 to extend into different grooves 21. That is, when the quick release component 32 releases the first vertical tube 2 and the clamping body 31, the person rotates the handlebar 1 to drive the first vertical tube 2 to rotate, so that the first vertical tube 2 rotates relative to the clamping body 31, thereby making the axis of the handlebar 1 parallel to the end face of the front wheel, which is convenient for parking against the wall. At the same time, when released, the first vertical tube 2 can also rotate in the vertical direction relative to the clamping body 31, so that the handlebar 1 rotates relative to the clamping component 3, thereby making the handlebar 1 parallel to the end face of the front wheel.

[0048] The number of grooves 21 can be multiple, and the multiple grooves 21 are arranged at intervals in the circumference of the first vertical tube 2. For example, the handlebar 1 can be moved so that the handlebar 1 has multiple included angles relative to the front wheel end face, or in other words, the handlebar 1 has multiple tilt angles relative to the front wheel end face, so that the rider can rotate the handlebar 1 to different angles relative to the front wheel end face.

[0049] The handlebar 1 steering assembly of this utility model, by setting an elastic element 42 and grooves 21, facilitates the extension of the elastic element 42 into different grooves 21 when the handlebar 1 rotates and drives the first vertical tube 2 to rotate. This allows the axis of the handlebar 1 to be parallel to the front wheel end face or to have different angles with the front wheel end face. This makes it convenient to rotate the handlebar 1 for storage when the vehicle is parked against a wall, thereby reducing the footprint. Compared with the rotatable telescopic vertical tube in the prior art, this design is simpler and more convenient to operate. At the same time, the design of the elastic element 42 and multiple grooves 21 makes it easy to return the handlebar 1 to its original position when parked or ridden, improving the ease of use.

[0050] In some embodiments, the elastic member 4 includes an abutment member 41 and an elastic member 42. The clamping body 31 is provided with a mounting groove 3121. The elastic member 42 is installed in the mounting groove 3121. The abutment member 41 is connected to the elastic member 42 to extend out of the mounting groove 3121 and abut against the outer peripheral surface of the first vertical tube 2.

[0051] Specifically, such as Figures 1 to 6 As shown, one end of the abutment 41 is connected to the elastic element 42. The elastic element 42 applies a force to the abutment 41 so that the abutment 41 extends out of the mounting groove 3121 and abuts against the outer circumferential surface of the first vertical tube 2. In other words, the abutment 41 extends out of the mounting groove 3121 to enter different grooves 21, so that the handlebar 1 can be parked against the wall or returned to its original position. At the same time, the elastic element 42 keeps the abutment 41 in contact with the outer surface of the first vertical tube 2. When the quick-release component 32 releases the clamping body 31 and the first vertical tube 2, the first vertical tube 2 tends to move downward under the action of gravity. The elastic element 42 keeps the abutment 41 in contact with the outer surface of the first vertical tube 2, thereby creating a certain friction between the first vertical tube 2 and the clamping body 31 to prevent the first vertical tube 2 from moving directly downward when released. At the same time, when rotating the first vertical tube 2, the friction between the first vertical tube 2, the clamping body 31, and the elastic element 42 must be exceeded to rotate the first vertical tube 2. To prevent the first vertical tube 2 from moving downward and rotating when the quick-release component 32 is released and unlocked under non-stress conditions, thus improving stability and safety during use.

[0052] In some embodiments, the mounting groove 3121 includes a first segment 31211 and a second segment 31212 that are interconnected. The first segment 31211 is located near one end of the first vertical pipe 2, and the cross-sectional area of ​​the first segment 31211 is larger than the cross-sectional area of ​​the second segment 31212.

[0053] The abutting member 41 includes an abutting body 412 and a limiting part 411 connected in sequence. The cross-sectional area of ​​the limiting part 411 is larger than the cross-sectional area of ​​the abutting body 412. The limiting part 411 fits in the first section 31211, and the abutting body 412 fits in the second section 31212.

[0054] Specifically, such as Figures 1 to 6 As shown, one end of the abutting body 412 is connected to the limiting part 411, and the other end of the abutting body 412 is connected to the elastic member 42. One end of the elastic member 42 is located at the bottom of the second segment 31212, and the other end of the elastic member 42 is connected to one end of the abutting body 412, while the other end of the abutting body 412 is connected to the limiting part 411.

[0055] The cross-sectional area of ​​the first segment 31211 in the direction orthogonal to the extension direction of the first vertical tube 2 is greater than the cross-sectional area of ​​the second segment 31212 in the same direction. Simultaneously, the cross-sectional area of ​​the limiting part 411 in the direction orthogonal to the extension direction of the first vertical tube 2 is smaller than the cross-sectional area of ​​the abutting body 412 in the same direction. The limiting part 411 fits within the first segment 31211, so that when the first vertical tube 2 is rotated, the elastic member 42 contracts, and the limiting part 411 moves closer to the second segment 31212, but cannot enter the second segment 31212 to limit the movement of the limiting part 411. This prevents excessive compression of the elastic member 42 due to movement of the limiting part 411, improving the stability of the elastic member 42 and the abutting body 412. By limiting the movement of the abutting member 41 within the mounting groove 3121, the service life of the quick-release component 32 and the elastic member 42 is improved.

[0056] Furthermore, the first segment 31211 and the second segment 31212 are cylindrical, the abutting body 412 and the limiting part 411 are cylindrical, the abutting body 412 is at least partially fitted inside the second segment 31212, and the radial dimension of the second segment 31212 is smaller than the radial dimension of the first segment 31211, and the radial dimension of the abutting body 412 is smaller than the radial dimension of the limiting part 411, thereby limiting the movement of the limiting part 411 in the mounting groove 3121 and preventing the elastic member 42 from being over-compressed.

[0057] In some embodiments, the abutment 41 further includes a protrusion 413, which protrudes from one end of the limiting portion 411 away from the abutment body 412. The protrusion 413 is at least partially spherical or a regular polyhedron, and the shape of the groove 21 corresponds to the shape of the protrusion 413.

[0058] Specifically, such as Figures 1 to 6 As shown, the protrusion 413 is located at the end of the limiting part 411 facing the first vertical tube 2, so that the protrusion 413 extends into the groove 21 and cooperates with the groove 21 to provide damping during rotation. At the same time, when the protrusion 413 extends into different grooves 21 after rotation, the protrusion 413 impacts the inner wall of the groove 21, generating sound and vibration, providing tactile feedback when the first vertical tube 2 is rotated, thus improving the user experience. Furthermore, since no large frictional force is required between the first vertical tube 2 and the elastic component 4 during rotation, the protrusion 413 reduces the frictional force between the first vertical tube 2 and the elastic component 4, facilitating the rotation of the first vertical tube 2. For example, the protrusion 413 is at least partially spherical or a regular polyhedron, and the shape of the groove 21 corresponds to the shape of the protrusion 413. After the protrusion 413 leaves the groove 21, it contacts the remaining outer surface of the first vertical tube 2. Since there is only point contact between the protrusion 413 and the outer surface of the first vertical tube 2, the rotational resistance is reduced, improving ease of use.

[0059] In other words, the shape of the groove 21 corresponds to the shape of the protrusion 413, so that the plane or curved surface of the protrusion 413 facing the groove 21 fits into the groove 21, thereby increasing the contact area and friction of the protrusion 413 in the groove 21 after rotation. This improves the friction between the first vertical tube 2 and the protrusion 413 after rotation and before the quick-release component 32 is fixed, so as to avoid the first vertical tube 2 from rotating under the action of external force, reduce the sensitivity of the first vertical tube 2 when rotating, and improve the convenience and stability of use.

[0060] Furthermore, there are multiple elastic components 4, which are arranged at intervals along the circumference of the first vertical tube 2. This ensures convenient and stable rotation and prevents damage to a single elastic component 42 from causing the handlebar 1 to fail to return to its original position or stop firing at a preset angle against the wall.

[0061] In some embodiments, the handlebar 1 steering assembly further includes a sliding plug 5, which engages with the lower end of the first vertical tube 2. The clamping body 31 has a through hole 311 extending through the clamping body 31 along the axial direction of the first vertical tube 2. The first vertical tube 2 passes through the through hole 311 and engages with the sliding plug 5. The cross-sectional area of ​​the sliding plug 5 is greater than the cross-sectional area of ​​at least the upper end of the through hole 311.

[0062] Specifically, such as Figures 1 to 6 As shown, the sliding plug 5 is used to be installed inside the front fork assembly 6, and the clamping body 31 and the first vertical tube 2 are installed on the front fork assembly 6 of the vehicle. The sliding plug 5 is located at the lower end of the first vertical tube 2, and the clamping body 31 is sleeved on the first vertical tube 2 above the sliding plug 5. In other words, the clamping body 31 is provided with a through hole 311 so that the first vertical tube 2 passes through the through hole 311 and extends into the front fork assembly 6 to connect with the sliding plug 5. This prevents the first vertical tube 2 from moving downward and disengaging from the front fork or the clamping body 31 of the vehicle when it moves in the vertical direction, thereby improving the stability of the handlebar 1 when it moves up and down.

[0063] Furthermore, the cross-sectional area of ​​the sliding plug 5 is greater than the cross-sectional area of ​​at least the upper end of the perforation 311. For example, the cross-sectional area of ​​the sliding plug 5 on the orthogonal and vertical surfaces is greater than the cross-sectional area of ​​at least the upper end of the orthogonal and vertical surfaces of the perforation 311, so as to prevent the sliding plug 5 from disengaging from the fork and clamping body 31 during vertical movement, thereby improving the stability and safety of use. A preset gap is provided between the outer peripheral surface of the sliding plug 5 and the inner wall surface of the fork assembly 6, so that the sliding plug 5 moves more smoothly within the fork assembly 6.

[0064] Meanwhile, the cross-sectional area of ​​the lower part of the perforation 311 is greater than the cross-sectional area of ​​the upper part, so that the upper part of the vehicle front fork assembly 6 extends into the perforation 311 at the lower end of the clamping body 31 so that the lower end of the clamping body 31 is fixed to the front fork assembly 6.

[0065] In some embodiments, at least a portion of the cross-section of the end of the first vertical tube 2 away from the clamping body 31 is larger than the cross-sectional area of ​​at least the upper end of the through hole 311. Setting the cross-sectional area of ​​the upper end of the first vertical tube 2 in the orthogonal and vertical directions to be larger than the cross-sectional area of ​​the upper end of the through hole 311 prevents the first vertical tube 2 from fully extending into the fork assembly 6 during installation without the handlebars 1 installed, thereby improving stability and safety during installation.

[0066] In some embodiments, the quick-release component 32 includes a cam wrench 321, a rotating shaft 322, and a first connector 323. The upper end of the clamping body 31 has an opening, and the cam wrench 321 is provided on one side of the opening. The first connector 323 passes through the opening and the clamping body 31 from the other side of the opening and is connected to the rotating shaft 322.

[0067] The cam wrench 321 is sleeved on the rotating shaft 322. The cam wrench 321 rotates relative to the rotating shaft 322 to press and fix the upper end of the clamping body 31 against the first vertical tube 2 or to unlock and rotate it.

[0068] Specifically, such as Figures 1 to 6 As shown, the clamping body 31 has an opening at the upper end. The clamping body 31 includes an upper clamping body 312 and a lower clamping body 313. The lower end of the upper clamping body 312 and the upper end of the lower clamping body 313 are connected. Both the upper clamping body 312 and the lower clamping body 313 have openings. The first connecting piece 323 passes through the upper clamping body 31 at one end of the opening and is connected to the rotating shaft 322 through the upper clamping body 31 on both sides of the opening. A cam wrench 321 is sleeved on the rotating shaft 322. The cam wrench 321 rotates to press and fix the first vertical tube 2 and the upper clamping body 31 or release them to rotate and move up and down.

[0069] A clamping screw 7 is installed on the lower clamping body 31. The clamping screw 7 passes through the opening of the lower clamping body 31 at one end of the opening and is threaded to the lower clamping body 31 on the other side of the opening to press and fix the second vertical tube 61 fixed in the through hole 311 of the lower clamping body 313. Furthermore, a set screw 8 can also be provided. The set screw 8 passes through the lower clamping body 313 and is connected to the second vertical tube 61 to fix the lower clamping body 313 to the front fork assembly 6.

[0070] The handlebar 1 steering assembly of this utility model embodiment is equipped with a quick-release component 32. The cam wrench 321 on the quick-release component 32 rotates to press and fix the first vertical tube 2 and the upper clamping body 312, or to release the first vertical tube 2 so that the first vertical tube 2 can rotate and move up and down, which improves the convenience of fixing or releasing the first vertical tube 2. The first vertical tube 2 can be fixed or released simply by rotating the cam wrench 321, which improves the convenience of turning the handlebar 1 when the vehicle is parked against a wall or when the vehicle is in contact with the wall. At the same time, a groove 21 is provided on the first vertical tube 2 to facilitate the accurate return of the handlebar 1 to its original position.

[0071] The vehicle of this utility model embodiment also includes:

[0072] The handlebar 1 steering assembly is the handlebar 1 steering assembly described above.

[0073] Handlebar 1, handlebar 1 is installed at one end of the handlebar 1 steering assembly, handlebar 1 includes a stem tube, and a first vertical tube 2 is fitted inside the stem tube;

[0074] The fork assembly 6 is mounted on the end of the handlebar 1 steering assembly away from the handlebar 1. The fork assembly 6 includes a second vertical tube 61, which extends into the clamping body 31 from the lower end face of the clamping body 31. The quick-release component 32 is used to fix and release the first vertical tube 2 and the second vertical tube 61.

[0075] The frame includes a head tube 10, which fits on the outer circumferential surface of the fork steerer tube and is located below the clamping member 3.

[0076] Specifically, such as Figures 1 to 6 As shown, the second vertical tube 61 extends into the clamping body 31 from the lower end of the clamping body 31. That is, the second vertical tube 61 extends into the through hole 311 of the lower clamping body 313 from the bottom, so as to fix the lower clamping body 313 on the second vertical tube 61, and then the handlebar 1 steering assembly is mounted on the front fork assembly 6. The front fork assembly 6 is rotatably mounted on the frame. The quick release component 32 presses and fixes the first vertical tube 2 and the upper clamping body 312 by rotating the cam wrench 321, or releases the first vertical tube 2 and the upper clamping body 312 by rotating the cam wrench.

[0077] Simultaneously, by installing or removing the clamping screw 7, the lower clamping body 313 and the second vertical tube 61 can be fixed or released, thereby enabling the quick-release component 32 to be used to fix and release the first vertical tube 2 and the second vertical tube 61, improving the convenience of vehicle rotation and installation, and facilitating user self-installation.

[0078] The vehicle of this utility model embodiment is equipped with a handlebar 1 steering component, which makes it easy to rotate the handlebar 1 for storage when the vehicle is parked against a wall, thereby reducing the footprint and making the operation simple and convenient.

[0079] In some embodiments, the vehicle also includes a backlash elimination knob 9, which is threadedly connected to the lower end of the clamping body 31. The end of the backlash elimination knob 9 away from the clamping body 31 is in contact with the vehicle frame. The backlash elimination knob 9 is rotated to move the vehicle frame and the clamping component 3 closer or further apart.

[0080] Specifically, such as Figures 1 to 6As shown, during vehicle installation, a gap exists between the second vertical tube 61 and the head tube 10 on the vehicle, causing the second vertical tube 61 to wobble during use. By setting a gap-reducing knob 9, the upper end of which is threadedly connected to the clamping body 31, the gap-reducing knob 9 rotates to make its lower end contact the head tube 10, thereby fixing the second vertical tube 61 to the lower clamping body 313. The gap-reducing knob 9 contacts the head tube 10, and the lower end of the gap-reducing knob 9 contacts the head tube 10. For example, an existing bearing is installed on the head tube 10, and the bearing at least partially contacts the knob. For example, the inner bearing of the bearing can contact the lower end of the gap-reducing knob 9 to avoid friction between the handlebar 1 and the head tube 10 on the frame when the handlebar 1 is turned, thus avoiding unnecessary wear of the gap-reducing knob 9 during use.

[0081] In this embodiment of the vehicle, a gap-eliminating knob 9 is provided. When installing the second vertical tube 61, the gap-eliminating knob 9 is rotated to keep it in contact with the vehicle's head tube 10. This prevents any vertical gap between the second vertical tube 61 and the head tube 10 that could cause shaking, and also minimizes the radial gap between the outer circumference of the second vertical tube 61 and the head tube 10 that could cause shaking of the second vertical tube 61 during driving, thus improving stability and safety.
