Description

Technical Field

[0001] This utility model belongs to the field of scooter technology, and in particular relates to a foldable scooter. Background Technology

[0002] With the continuous improvement of living standards, scooters, as a representative of fashionable sports equipment, are favored by many teenagers. For adults, scooters can not only be used for entertainment, but also for physical exercise or as the most advantageous green and environmentally friendly means of transportation to replace walking. Most scooters on the market are foldable, which reduces the space occupied by the scooter and makes it easy to store and carry. However, the folding structure of these scooters is relatively complicated. When users want to fold the scooter, they need to go through cumbersome steps to fold it up. The operation is complicated, time-consuming and laborious. Utility Model Content

[0003] To address the shortcomings of existing technologies, a scooter that is easy for users to fold and unfold is provided.

[0004] This utility model is achieved using the following technical solution: a foldable scooter, comprising a handlebar, foot pedals, and a slanted tube connecting the handlebar and foot pedals, wherein a folding locking mechanism is provided between the slanted tube and the foot pedals, and the folding locking mechanism includes:

[0005] A locking plate is fixed to the front end of the foot pedal, and the lower end of the inclined tube is rotatably connected to the locking plate; the outer periphery of the locking plate is arc-shaped, and outwardly opening unfolding locking grooves and folding locking grooves are provided at intervals along the outer periphery of the arc.

[0006] A displacement member is movably disposed inside the inclined tube. The inclined tube is provided with a sliding groove, and the displacement member is restricted to move within the sliding groove. The displacement member is provided with a locking protrusion, which extends laterally to the outside of the inclined tube via a corresponding guide groove on the side wall of the inclined tube, and selectively engages with the unfolding locking groove or the folding locking groove. The guide groove and the sliding groove are in the same direction.

[0007] A spring, disposed inside the inclined tube, acts on the displacement member to provide a preload force that drives the locking protrusion to remain locked in the unfolding locking groove or folding locking groove.

[0008] Rotate the handle to rotatably connect it to the inclined tube, with one end extending into the inclined tube and being connected to the displacement component. Operating the handle can drive the displacement component to move along the slide groove, causing the locking protrusion to move along the guide groove and disengage from the unfolding locking groove or folding locking groove, thereby allowing the inclined tube to rotate relative to the foot pedal for folding or unfolding.

[0009] When in use, if folding is required, the user rotates the handle to move the displacement component inside the slant tube, causing the locking protrusion to disengage from the unfolding locking groove. After disengagement, the slant tube can rotate relative to the foot pedal for folding. The locking protrusion moves along the outer periphery of the locking plate. When it moves to the folding locking groove position, the locking protrusion automatically extends into the folding locking groove under the action of the spring, thus completing the folding and locking of the scooter.

[0010] When unfolding is required, the user rotates the handlebars again, causing the displacement component inside the slant tube to move, thereby disengaging the locking protrusion from the folding locking slot. After disengagement, the slant tube can rotate relative to the foot pedal to unfold. The locking protrusion will move in the opposite direction along the outer periphery of the locking plate. When it moves to the unfolding locking slot position, the locking protrusion will automatically extend into the unfolding locking slot under the action of the spring, thus completing the unfolding and locking of the scooter.

[0011] The faucet rod and the inclined tube are fixed in place, usually by welding or integral molding.

[0012] This solution allows users to unlock the scooter in either the unfolded or folded state simply by rotating the handlebars. Users only need to rotate the handlebars and slant tubes to switch between unfolded and folded states. Furthermore, the locking protrusions automatically engage with the unfolded or folded locking slots under the action of springs, making it very convenient.

[0013] Preferably, the inner wall of the inclined tube forms the groove, the outer wall of the displacement member contacts and slides with the inner wall of the inclined tube, and both the groove and the guide groove extend along the length of the inclined tube.

[0014] The inner wall of the inclined tube directly forms a groove that limits the movement of the displacement component, making the structure more compact and simple.

[0015] Preferably, the displacement member is fixed with a laterally extending pin, the pin passes through the displacement member and its two ends respectively form the locking protrusions, and one end of the rotating handle that extends into the inclined tube abuts against the pin; when the rotating handle is operated to rotate, the rotating handle abuts against the pin, causing the entire displacement member to move along the slide groove, thereby realizing the transmission connection between the rotating handle and the displacement member.

[0016] The above method can achieve the transmission connection between the rotating handle and the displacement component, which is simpler in terms of structural design.

[0017] Preferably, the end of the rotating handle that extends into the inclined tube is provided with a U-shaped groove structure, and the pin passes through the U-shaped groove.

[0018] The movement trajectory of the end of the rotating handle is a circular trajectory, while the movement trajectory of the pin is a straight trajectory along the guide groove or along the extension direction of the slide groove. Therefore, by passing the pin through the U-shaped groove, it is possible for the pin and the rotating handle to adapt to changes in position and avoid jamming.

[0019] Preferably, the spring is a compression spring, which extends along the length of the inclined tube. The end of the displacement member that abuts against the spring is provided with a circular boss, and one end of the spring is sleeved on the circular boss.

[0020] The above settings allow for better guidance and limitation of the spring's extension and retraction direction.

[0021] Preferably, the groove wall of the folding locking groove includes a front groove wall and a rear groove wall arranged opposite each other along the front-rear direction of the scooter. The front groove wall has an inclined surface in the opening area of ​​the folding locking groove, so that the opening area of ​​the folding locking groove has an open structure.

[0022] To ensure the locking strength of the scooter when unfolded, the springs used have high elasticity to provide sufficient locking force and prevent displacement of the components when the scooter travels over bumpy roads, which could cause the locking protrusion to disengage from the unfolded locking groove and create a safety hazard. Similarly, when the scooter is folded, the locking protrusion may not easily disengage from the folding locking groove, requiring significant force to rotate the handlebars, with the required force increasing with the rotation angle. To avoid this, a slope is designed on the front wall of the folding locking groove, creating an open structure. This allows the user to disengage the locking protrusion with a smaller rotation of the handlebars, making it easier to use. It also facilitates the sliding of the locking protrusion into the folding locking groove for locking.

[0023] Preferably, the rotating handle includes a straight fitting section extending along the length of the inclined tube, and an operating section located at the end of the straight fitting section and tilted away from the inclined tube; the straight fitting section is fitted with the outer wall of the inclined tube.

[0024] The above design has a foolproof function. The straight section of the rotating handle is flush with the outer wall of the inclined tube, reducing the risk of being accidentally hooked by external objects. The operating section requires the user to actively pinch and pull it to apply force to rotate. This structural difference significantly reduces the possibility of misoperation.

[0025] Preferably, the extension directions of the unfolding locking groove, the folding locking groove, and the guide groove all pass through the rotation axis of the inclined tube.

[0026] Make:

[0027] When the locking protrusion engages with the unfolding locking groove, the guide groove aligns with the unfolding locking groove;

[0028] When the locking protrusion engages with the folding locking groove, the guide groove aligns with the folding locking groove.

[0029] The above settings can reduce the lag when the card slot protrusion moves, making it easier for users to operate.

[0030] Compared with existing technologies, the advantages of this invention are as follows: This solution allows the scooter to be unlocked in either the unfolded or folded state simply by rotating the handlebar. Users only need to rotate the handlebar and the slant tube to switch between unfolding and folding modes. Furthermore, the locking protrusion automatically engages with the unfolding or folding locking slot under the action of a spring, which is very convenient. Additionally, a slope is provided on the front wall of the folding locking slot, making the opening area of ​​the folding locking slot open. This allows users to disengage the locking protrusion from the folding locking slot with a smaller rotation of the handlebar, facilitating user operation. Attached Figure Description

[0040] The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

[0041] like Figure 1 As shown, this embodiment discloses a foldable scooter, which includes a handlebar 1, foot pedals 2, and a slant tube 3 connecting the handlebar 1 and the foot pedals 2. A folding locking mechanism is provided between the slant tube 3 and the foot pedals 2. The handlebar 1 includes a detachably connected upper rod 11 and a lower rod 12. The upper rod 11 is connected to the handlebar, and the lower rod 12 is connected to the front wheel. The detachable fixing method of the upper rod 11 and the lower rod 12 is the same as that of any existing scooter handlebar. The lower rod 12 is integrally formed with the slant tube 3.

[0042] like Figures 1 to 8 As shown, a locking plate 5 is fixed to the front end of the foot pedal 2. The locking plate 5 has a U-shaped structure, and the lower end of the inclined tube 3 is located between the slots of the U-shaped structure of the locking plate 5 and is rotatably connected to the locking plate 5. The locking plate 5 has a transverse through shaft hole 53, and the inclined tube 3 has a rotating shaft 31 that extends into the shaft hole 53 and is rotatably connected to the shaft hole 53. The outer periphery of the walls on opposite sides of the locking plate 5 is arc-shaped, and outwardly opening unfolding locking grooves 51 and folding locking grooves 52 are provided at intervals along the outer periphery of the arc. The unfolding locking groove 51 is located at the front end of the folding locking groove 52.

[0043] A movable displacement member 8 is provided inside the inclined tube 3. The circumferential inner wall of the inclined tube 3 forms a groove to limit the movement of the displacement member 8. The circumferential outer wall of the displacement member 8 contacts and slides with the circumferential inner wall of the inclined tube 3, allowing the displacement member 8 to slide along the length of the inclined tube 3. A laterally extending pin 6 is fixed on the displacement member 8. The pin 6 passes laterally through the displacement member 8, and its two ends respectively form locking protrusions 61. The locking protrusions 61 can selectively engage with the unfolding locking groove 51 and the folding locking groove 52. When the locking protrusion 61 engages with the unfolding locking groove 51, it corresponds to the unfolded and locked state of the scooter. When the locking protrusion 61 engages with the folding locking groove 52, it corresponds to the folding and locked state of the scooter.

[0044] Both the inclined tube 3 and the displacement component 8 are provided with clearance grooves 82 with openings on the front and rear sides. The rotating handle 4 passes through the clearance grooves 82 of the inclined tube 3 and the displacement component 8 and extends into the displacement component 8. Furthermore, the end of the rotating handle 4 that extends into the displacement component 8 is provided with a U-shaped groove 43 structure. The pin 6 passes through the U-shaped groove 43, allowing the rotating handle 4 to move against the pin 6, thereby achieving a transmission connection between the rotating handle 4 and the displacement component 8. The rotating handle 4 is rotatably connected to the inclined tube 3, and the other end of the rotating handle 4 is located on the outside of the inclined tube 3.

[0045] On both sides of the inclined tube 3, there are guide grooves 62 through which the locking protrusions 61 of the pin 6 pass. The guide grooves 62 and the sliding groove extend in the same direction. Both extend along the length of the inclined tube 3. The length of the guide grooves 62 is greater than the diameter of the pin 6.

[0046] Furthermore, the straight lines extending from the guide groove 62, the unfolding locking groove 51, and the folding locking groove 52 all pass through the rotation axis of the inclined tube 3. When the locking protrusion 61 engages with the unfolding locking groove 51, the guide groove 62 aligns with the unfolding locking groove 51; when the locking protrusion 61 engages with the folding locking groove 52, the guide groove 62 aligns with the folding locking groove 52. When the outer end is rotated, the inner end of the rotating handle 4 will abut against the pin 6, causing the locking protrusion 61 to move. At this time, the locking protrusion 61 will move along the guide groove 62, thereby disengaging from the unfolding locking groove 51 or the folding locking groove 52. At this time, the entire inclined tube 3 can rotate, thus completing the switching between folding and unfolding.

[0047] like Figures 6 to 8 As shown, a spring 7 is provided inside the inclined tube 3. The spring 7 is a compression spring and extends along the length of the inclined tube 3. The end of the displacement member 8 that abuts against the spring 7 is provided with a circular boss 81, and one end of the spring 7 is sleeved on the circular boss 81. An abutment member 71 is fixed inside the inclined tube 3 to abut the other end of the spring 7, so that the spring 7 acts on the displacement member 8 to move towards the lower end of the inclined tube 3, so as to provide a preload force to drive the locking protrusion 61 to remain locked in the unfolding locking groove 51 or the folding locking groove 52.

[0048] like Figure 7 As shown, the groove wall of the folding locking groove 52 includes a front groove wall 521 and a rear groove wall 522 arranged opposite to each other along the front and rear direction of the scooter. The front groove wall 521 has an inclined surface 523 in the opening area of ​​the folding locking groove 52, so that the opening area of ​​the folding locking groove 52 has an open structure.

[0049] like Figure 4 and Figure 5 As shown, the rotating handle 4 includes a straight fitting section 41 extending along the length of the inclined tube 3, and an operating section 42 located at the end of the straight fitting section 41 and tilted away from the inclined tube 3; the straight fitting section 41 is fitted with the outer wall of the inclined tube 3.

[0050] When folding is required, the user rotates the handle 4, causing the displacement member 8 inside the slant tube 3 to move, thereby causing the locking protrusion 61 to disengage from the unfolding locking groove 51. After disengagement, the slant tube 3 can rotate relative to the foot pedal 2 for folding. The locking protrusion 61 will move along the outer periphery of the locking plate 5. When it moves to the folding locking groove 52, under the action of the spring 7, the locking protrusion 61 will automatically extend into the folding locking groove 52, thereby completing the folding and locking of the scooter.

[0051] When it needs to be unfolded, the user rotates the handlebar 4 again, causing the displacement member 8 inside the slant tube 3 to move, thereby causing the locking protrusion 61 to disengage from the folding locking groove 52. After disengagement, the slant tube 3 can rotate relative to the foot pedal 2 to unfold. The locking protrusion 61 will move in the opposite direction along the outer periphery of the locking plate 5. When it moves to the unfolding locking groove 51, under the action of the spring 7, the locking protrusion 61 will automatically extend into the unfolding locking groove 51, thereby completing the unfolding and locking of the scooter.
