DETAILED DESCRIPTION

[0033] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0034] like Figure 1 and Figure 2As shown, a scooter bar includes a bar 1 and a folding mechanism 2. The folding mechanism 2 is hollow, one end of the bar 1 is plugged into the upper end of the folding mechanism 2, and the lower end of the folding mechanism 2 is fixedly connected to the pedal. When rotating, the bar is folded by rotating the folding mechanism 2 fixedly connected to the bar, and the storage of the scooter is completed, which greatly reduces the storage space of the scooter.

[0035] like Figure 3 As shown, the folding mechanism 2 includes an upper rotating body 3 mounted on the lower end of the vehicle bar 1 and a lower fixed body 4 matched with the upper rotating body 3. The upper rotating body 3 and the lower fixed body 4 are a pair of columns with inclined surfaces as rotating mating surfaces. The column has a large space inside to accommodate a large volume of the mechanism, which is more convenient for installation.

[0036] The contact surface between the upper rotating body 3 and the lower fixed body 4 is an inclined surface, and the inclined surface is at an angle of 45 degrees to the axis of the vehicle rod 1. A mounting groove 5 is provided on the lower end surface of the upper rotating body 3, and the mounting groove 5 is arranged around the center of the inclined surface. A circle of convex edges 6 matching the mounting groove 5 is fixedly provided on the upper end surface of the lower fixed body 4. The mounting groove 5 and the convex edges 6 are arranged in an annular shape on the outer periphery of the center of the inclined surface. A rotating device 7 and a locking device 8 are provided in the upper rotating body 3 and the lower fixed body 4. The annular mounting groove 5 and the convex edges 6 can be completely interlocked with each other during rotation, thereby ensuring the reliability of the rotation between the upper rotating body 3 and the lower fixed body 4.

[0037] The first clamping sleeve 10 is a circular snap ring 22, on one end of which a fixing plate 23 is fixedly arranged, the fixing plate 23 is fixedly connected to the lower end of the upper rotating body 3, and the inner diameter of the snap ring 22 is the same as the outer diameter of the bearing 9. The second clamping sleeve 11 is a circular snap ring 24, on one end of which a fixing plate 25 is fixedly arranged, the fixing plate 25 is fixedly connected to the upper end of the lower fixed body 4, and the outer diameter of the snap ring 24 is the same as the inner diameter of the bearing 9. The rotation between the upper rotating body 3 and the lower fixed body 4 is completed by respectively sleeve-mounting the two snap rings 22 and 24 with different diameters on the inner and outer sides of the bearing 9, so that the resistance during rotation is smaller and the rotation is smoother.

[0038] like Figure 4 As shown, the rotating device 7 includes a bearing 9, the axis of which is perpendicular to the rotating mating surface, the inner ring of the bearing 9 is fixedly connected to the upper rotating body 3 through a first compression sleeve 10, and the outer ring of the bearing 9 is fixedly connected to the lower fixed body 4 through a second compression sleeve 11, so as to realize the relative rotation of the upper rotating body 3 and the lower fixed body 4. The setting of the bearing 9 assists the rotation between the upper rotating body 3 and the lower fixed body 4, greatly reduces the friction between the upper rotating body 3 and the lower fixed body 4, and makes the rotation smoother.

[0039] like Figure 5 As shown, the locking device 8 includes a locking button 12 arranged in the upper rotating body 3, and two locking columns 13 fixedly connected to the locking button 12, and the locking columns 13 are fixedly arranged on a connecting plate 16, and the connecting plate 16 is fixedly connected to the above-mentioned locking button 12 through a fastening bolt 17.

[0040] The locking column 13 and the connecting plate 16 are arranged in the lower fixed body 4, and a plurality of locking grooves 14 for accommodating the locking column 13 are provided in the upper rotating body 3. A group of positioning holes 18 for the locking column 13 to pass through are provided on the upper end surface of the lower fixed body 4. After the locking button 12 is pressed, the locking button 12 drives the locking column 13 to move downward until the locking column 13 leaves the locking groove 14 and the positioning hole 18, and the upper rotating body 3 and the lower fixed body 4 are unlocked and rotated. A spring 15 is arranged around the outer periphery of the locking button 12. When the locking button 12 is released, it moves upward under the action of the spring 15, and drives the locking column 13 to reset and pass through the positioning hole 18 to another group of locking grooves 14 of the upper rotating body 3, thereby locking the upper rotating body 3 and the lower fixed body 4.

[0041] A mounting hole is provided on the outer circumferential surface of the upper rotating body 3, and the locking button 12 is movably arranged in the mounting hole. A clamping block 19 is fixedly provided on the side of the locking button 12 along the axis of the locking button 12, and a limiting groove 20 is provided on the inner side of the mounting hole to cooperate with the clamping block 19. When the locking button 12 is pressed, the locking button 12 can be moved in and out through the cooperation between the clamping block 19 and the limiting groove 20, and the circumferential rotation of the locking button 12 is limited to prevent the locking button 12 from rotating when pressed.

[0042] A baffle 21 is provided on the outer surface of the lower fixed body 4. The baffle 21 is used to seal the installation space in the folding mechanism 2, shield and protect the internal mechanism of the folding mechanism 2, greatly reduce the erosion of the internal mechanism by external rain and dust, and avoid small stones entering the folding mechanism 2 to the greatest extent to cause wear on the internal parts, effectively extending the service life of the folding mechanism 2.

[0043] When in use, the vehicle bar 1 is in a vertical state, the locking column 13 passes through the positioning hole 18 and a group of locking grooves 14, and the upper rotating body 3 and the lower fixed body 4 are in a locked state. When stored, the locking button 12 is pressed, and the locking button 12 pushes the locking column 13 fixedly connected to the connecting plate 16 to move downward, so that the locking column 13 disengages from the locking groove 14 and the positioning hole 18. At this time, the upper rotating body 3 is rotated to make the vehicle bar 1 and the lower fixed body 4 90 degrees. The locking button 12 is released and the reset spring 15 pushes the locking button 12 upward, driving the locking column 13 to move upward and pass through the positioning hole 18 and another group of locking grooves 14 to achieve locking between the upper rotating body 3 and the lower fixed body 4.

[0044] like Figure 8 and 9 As shown, the vehicle bar includes an adjustment rod 26 , a support rod 29 , and a main body cover 30 . The adjusting rod 26 and the supporting rod 29 are both cylindrical rod bodies. The supporting rod 29 is a hollow structure. The main body sleeve 30 includes a connecting body 32 and a locking body 31. The connecting body 32 and the locking body 31 are integrally formed and have their inner cavities communicated. The inner diameter of the connecting body 32 matches the outer diameter of the supporting rod 29 and is slightly larger than the outer diameter of the supporting rod 29. The inner diameter of the locking body 31 matches the outer diameter of the adjusting rod 26 and is slightly larger than the outer diameter of the adjusting rod 26. The transition section between the connecting body 32 and the locking body 31 forms a stepped platform. The upper end of the supporting rod 29 is inserted into the connecting body 32 and fastened by bolts, and its upper edge abuts against the inner wall of the stepped platform. The stepped platform can limit the supporting rod 29 and support the main body sleeve 30, so that the connection between the supporting rod 29 and the main body sleeve 30 is more reliable. The adjusting rod 26 is inserted into the supporting rod 29 and the main body sleeve 30 and can move up and down. The adjusting rod 26 is coaxially arranged with the supporting rod 29.

[0045] The locking body 31 is provided with a first locking device and a second locking device in sequence from top to bottom to double lock the support rod 29. The first locking device includes a plurality of clamping plates 37 and a conical screw sleeve 38 integrally formed at the front end of the locking body 31 and evenly distributed along the circumference of the locking body 31. In this embodiment, there are three clamping plates 37, which are evenly distributed along the circumference of the locking body 31. An external thread is provided below the clamping plate 37, and an internal thread matching the external thread is provided on the inner wall of the conical screw sleeve 38. The clamping plate 37 is clamped or loosened on the adjusting rod 26 by twisting the conical screw sleeve 38 to realize the telescopic positioning of the adjusting rod 26. The clamping plate 37 and the conical screw sleeve 38 are used to lock the adjusting rod 26. The structure is simple and reliable, and it is easy to process. The second locking device includes a plurality of steel balls 33 distributed along the circumference of the locking body 31 and movable radially along the locking body 31, and a steel ball pressing sleeve 34 capable of pressing the steel balls 33 against the outer wall of the adjusting rod 26. The steel balls 33 are installed in circular holes opened along the circumference of the locking body 31. In this embodiment, five steel balls 33 are arranged, which are evenly distributed along the circumference of the locking body 31. The freedom of the steel balls 33 in the circumferential and axial directions of the locking body 31 is limited by the circular holes, and the steel balls 33 can move freely in the radial direction of the locking body 31. The diameter of the steel balls 33 is greater than the depth of the circular holes, and the steel balls 33 protrude from the circular holes. A pressing boss 39 for pressing the steel balls and a clearance groove 40 for the steel balls to move outward are arranged on the inner wall of the steel ball pressing sleeve 34. The steel ball pressing sleeve 34 can move along the axial direction of the locking body 31 to press or release the steel balls 33. The outer wall of the adjusting rod 26 is concavely provided with a plurality of groups of slots 27 distributed along the axial direction of the adjusting rod 26, and each group of slots 27 is composed of 5 circular slots 27 distributed along the circumference of the adjusting rod 26, which cooperate with the steel ball 33, and the steel ball 33 can be embedded in the slot 27 to lock the adjusting rod 26. In this embodiment, three groups of slots 27 are provided, and three height adjustments can be achieved. The outer wall of the adjusting rod 26 is also concavely provided with an axially penetrating positioning groove 28, and a limiting edge is provided inside the main body sleeve 30 to cooperate with the positioning groove 28, which is used to limit the relative rotation of the adjusting rod 26 and the main body sleeve 30, so as to ensure the precise cooperation between the steel ball 33 and the slot 27, so that the steel ball 33 can be accurately embedded in the slot 27. A return spring 35 is arranged in the steel ball pressing sleeve 34. The return spring 35 is sleeved on the locking body 31 and is located below the pressing boss 39 of the steel ball pressing sleeve 34. Its upper end abuts against the lower edge of the pressing boss 39, and its lower end abuts against the lower convex edge of the outer wall of the locking body 31. The setting of the return spring 35 can make the steel ball pressing sleeve 34 automatically return to the pressing position after the adjustment rod 26 is adjusted to the corresponding position. A snap ring 36 is also sleeved on the locking body 31. The snap ring 36 is located in the clearance groove 40 of the steel ball pressing sleeve 34, and its upper end abuts against the upper convex edge of the outer wall of the locking body 31. The snap ring 36 cooperates with the clearance groove 40 to limit the position of the steel ball pressing sleeve 34, avoids excessive return, and prevents the steel ball from falling out. At the same time, the upper convex edge of the outer wall of the locking body 31 can further limit the steel ball pressing sleeve 34.When the spring compression sleeve 312 moves downward, its position is limited by the stepped platform to prevent it from moving downward excessively. The distance between the stepped platform and the retaining ring 36 is greater than the height of the spring compression sleeve 312, providing a certain axial movement space for it. The height adjustment process of the scooter handle is as follows: first, loosen the conical nut 38 of the first locking device, the clamping piece 37 loosens the adjusting rod 26, then slide the steel ball pressing sleeve 34 downward, the pressing boss 39 leaves the steel ball 33, and the giving groove 40 provides space for the steel ball 33 to move outward, and the steel ball 33 breaks free from the restraint and pops out, leaving the slot 27 on the adjusting rod 26. The adjusting rod 26 is no longer constrained and can move up and down in the support rod 29 to complete the adjustment of the handle height. After the adjustment is completed, slide the steel ball pressing sleeve 34 upward to restore it to the clamping position, and press the steel ball 33 into another set of slots 27 to complete the locking of the adjusting rod 26, and then tighten the conical nut 38 to apply pressure to the clamping piece 37, so that the clamping piece 37 hugs the adjusting rod 26 to complete the secondary locking of the adjusting rod 26.
