Description

Technical Field

[0001] This utility model belongs to the technical field of children's scooters, and specifically relates to a folding scooter. Background Technology

[0002] A children's scooter is a type of children's vehicle that typically includes a base and handlebars. The rear wheel is located at the back of the base, and the front wheel is mounted on the front of the base. During use, the user tilts their body to rotate the base and the front wheel relative to each other, thereby controlling the scooter's direction.

[0003] To facilitate the storage and transportation of children's scooters, some models on the market feature handlebars that can be folded and flipped towards the base. Locking mechanisms are installed on the handlebars or base to maintain their relative position, as illustrated in Chinese utility model patent CN202021461173.0. A disclosed folding structure for a children's scooter includes a frame, a connecting frame, a rotating groove, and a locking slot. The connecting frame is integrally fixed to the end of the frame. The connecting frame has a rotating groove on its surface, and a locking slot is formed within the rotating groove. A flexible locking and unlocking adapter is rotatably mounted within the rotating groove. The adapter includes a rod, an axle, and a locking mechanism. The axle is rotatably connected to the rotating groove. A rod is fixed to the top of the outer wall of the axle. A flexible telescopic locking mechanism is installed on the outer wall of the rod, and the locking mechanism engages with the locking slot. The locking mechanism includes an outer shell, an adjusting groove, a lever, a latch, a slot, a spring, and a positioning post. The outer shell is fixedly connected to the rod. A latch is slidably inserted into the outer shell. A slot is formed on the surface of the axle, and the latch passes through the slot and engages with the locking slot. A positioning post is fixed to the top of the outer shell and the top of the latch, respectively, and a spring connects the positioning posts. An adjusting groove is formed on the surface of the outer shell, and a lever passing through the adjusting groove is fixed to the surface of the latch.

[0004] Although the structure described above is simple, the locking mechanism is easily accidentally activated during use, which can cause the adapter and connecting frame to fold unexpectedly, leading to accidents. Furthermore, since the adapter is located at the lower end of the handlebar and the locking mechanism is located on the adapter, the user needs to control the locking mechanism with one hand and grip the lower part of the handlebar with the other hand during the unfolding and folding of the scooter, making it inconvenient for the scooter to fold and unfold quickly.

[0018] The advantages of this utility model compared to the prior art are:

[0019] 1. In this utility model, after the top rod retracts relative to the bottom rod, the top rod can control the locking member to disengage from the locking groove through the transmission component, thereby allowing the handlebar to rotate relative to the base plate. However, when using a folding scooter, the top rod and bottom rod need to extend relative to each other and be fixed relative to each other by the control component. At this time, the top rod cannot control the locking member to disengage from the locking groove, thus preventing the handlebar and base plate from folding accidentally, which helps improve the safety of the folding scooter. Furthermore, when the top rod and bottom rod retract accidentally, the handlebar and base plate cannot rotate relative to each other immediately, giving the user reaction time and helping to avoid accidents. In this structure, controlling the relative retraction of the top rod and bottom rod allows the locking member to disengage from the locking groove, eliminating the need for the user to control the scooter with both hands separately, facilitating the quick unfolding and folding of the folding scooter, and making it convenient for the user to use and control.

[0020] 2. The hinge groove in this utility model facilitates the stable installation of the base plate and the base rod. Since the mounting groove is located at the bottom of the hinge groove, it prevents debris from entering the mounting groove during use and affecting the contraction of the first elastic element. This makes it easier for the user to control and helps extend the service life of the folding scooter. The guide protrusion prevents the locking element from entering the locking groove and disengaging from the mounting cavity, which helps the locking element to be stably installed in the mounting groove and makes it easier for the user to control.

[0021] 3. The locking rod and slot design in this utility model improves the connection strength between the handlebar and the base plate, prevents accidental damage to the locking components during use, and extends the service life of the folding scooter. Since the locking rod is mounted on the transmission component, it can be disengaged from the slot while the locking component is being driven by the top rod. The structure is simple and user-friendly. The two sets of slots facilitate keeping the handlebar and base plate folded, making storage and transportation of the folding scooter convenient. The curved surface or groove design allows the locking rod to switch between the two sets of slots. Users do not need to constantly drive the top rod during the rotation of the handlebar and base plate, making it easier for users to control the unfolding and folding of the scooter.

[0022] 4. In this utility model, the locking component can be disengaged from the positioning groove by the control component on the upper part of the top rod or the handle, so that the top rod and the bottom rod can slide relative to each other. The user can control the top rod and the bottom rod relative to each other with one hand while controlling the control component, which is convenient for the user to control the unfolding and folding of the folding scooter. The control port set at the upper end of the handle makes it easy for the user to control the control component, and the inclined drive surface makes it easy for the user to drive the locking component to move through the control component. The structure is simple and easy for the user to control the locking component. The fourth elastic component can prevent the control component from driving the locking component to move under the action of gravity, prevent the locking component from accidentally disengaging from the slot during use, and prevent the top rod and the bottom rod from accidentally sliding during use. This is conducive to the stable installation of the top rod and the bottom rod and improves the safety of the folding scooter.

[0023] 5. The setting of the limiting rod and the limiting groove in this utility model can limit the movement range of the transmission component, prevent the transmission rod from passing through the bottom rod and contacting the bottom plate, thus affecting the relative rotation of the bottom rod and the bottom plate, and making it convenient for the user to control the relative rotation of the bottom rod and the bottom plate; the setting of the guide slope facilitates the engagement or disengagement of the locking component and the locking groove, and facilitates the relative unfolding and folding of the handle and the bottom plate during use, making it convenient for the user.

[0024] 6. The deformable part, clamp, drive rod and cam in this utility model are designed to further fix the bottom rod and top rod relative to each other, avoid the bottom rod and top rod from accidentally retracting during use, improve the safety of the folding scooter, make it convenient for users to use, and the structure is easy for users to control, easy for users to adjust the length of the handle bar, and easy for the handle bar and the bottom plate to fold relative to each other.

[0051] The present invention will be further described below with reference to the accompanying drawings and specific embodiments:

[0052] See Figures 1 to 16As shown, a folding scooter includes a base plate 1 and a handlebar 2 rotatably connected. A grip 23 is provided on the handlebar 2. The base plate 1 has a first elastic element 33 and a locking element 3. The handlebar 2 has a locking groove 215. The first elastic element 33 drives the locking element 3 to engage with the locking groove 215, fixing the handlebar 2 relative to the base plate 1 and keeping the handlebar 2 in an unfolded state. The handlebar 2 includes a retractable top rod 22 and a bottom rod 21. The bottom rod 21 is rotatably connected to the base plate 1, and the grip 23 is disposed on the top rod 22. A control component 6 is movably mounted on the top rod 22 or the bottom rod 21 to control the relative fixation of the top rod 22 and the bottom rod 21; the bottom rod 21 is also provided with a transmission component 4 and a second elastic component, the second elastic component can drive the transmission component 4 away from the locking component 3, and control the relative extension of the top rod 22 and the bottom rod 21 to make the top rod 22 move away from the transmission component 4; control the top rod 22 to retract relative to the bottom rod 21, the top rod 22 can drive the transmission component 4 to move and control the locking component 3 to disengage from the locking groove 215 through the transmission component 4, so that the handle rod 2 can rotate relative to the base plate 1.

[0053] In the above structure, after the top rod 22 retracts relative to the bottom rod 21, the top rod 22 can control the locking member 3 to disengage from the locking groove 215 through the transmission component 4, thereby allowing the handlebar 2 to rotate relative to the base plate 1. However, when using the folding scooter, the top rod 22 and the bottom rod 21 need to extend relative to each other, and the top rod 22 and the bottom rod 21 are relatively fixed by the control component 6. At this time, the top rod 22 cannot control the locking member 3 to disengage from the locking groove 215, thereby preventing the handlebar 2 and the base plate 1 from folding accidentally, which helps to improve the safety of the folding scooter. Moreover, when the top rod 22 and the bottom rod 21 retract accidentally, the handlebar 2 and the base plate 1 cannot immediately rotate relative to each other, giving the user reaction time and helping to avoid accidents. In addition, in this structure, controlling the relative retraction of the top rod 22 and the bottom rod 21 can disengage the locking member 3 from the locking groove 215, so the user does not need to control the scooter with both hands separately, which facilitates the quick unfolding and folding of the folding scooter and makes it convenient for the user to use and control.

[0054] The base plate 1 of this utility model is provided with a hinge groove 11. The lower end of the bottom rod 21 is rotatably disposed in the hinge groove 11. The bottom of the hinge groove 11 is provided with a mounting groove 12. The locking member 3 is slidably disposed in the hinge groove 11. The locking member 3 includes a locking member body 31. The side of the locking member body 31 is provided with a wire protrusion. The locking member body 31 cooperates with the locking groove 215. The guide protrusion 32 can abut against the end of the locking groove 215 and prevent the locking member 3 from disengaging from the mounting groove 12. The hinge groove 11 facilitates the stable installation of the base plate 1 and the bottom rod 21. Since the mounting groove 12 is located at the bottom of the hinge groove 11, it prevents debris from entering the mounting groove 12 during use and affecting the contraction of the first elastic member 33. This facilitates user control and helps extend the service life of the folding scooter. The guide protrusion 32 can prevent the locking member 3 from entering the locking groove 215 and disengaging from the mounting cavity. This facilitates the stable installation of the locking member 3 in the mounting groove 12 and makes it convenient for the user to use and control.

[0055] In this embodiment, the lower end of the bottom rod 21 is provided with a hinge joint 214 that is adapted to the hinge groove 11. The hinge joint 214 has an arc-shaped sidewall. When the bottom rod 21 and the bottom plate 1 are rotated relative to each other, the locking body 31 can abut against the arc-shaped sidewall and slide relative to each other along the arc-shaped sidewall.

[0056] Preferably, the transmission component 4 is provided with a locking rod 41, and the base plate 1 is provided with a locking groove 13 adapted to the locking rod 41. The second elastic element can drive the transmission component 4 to reset and make the locking rod 41 engage with the locking groove 13, thereby fixing the handlebar 2 and the base plate 1 relatively. The setting of the locking rod 41 and the locking groove 13 helps to improve the connection strength between the handlebar 2 and the base plate 1, avoids accidental damage to the locking component 3 during use, and helps to extend the service life of the folding scooter. Since the locking rod 41 is set on the transmission component 4, the locking rod 41 can be controlled to disengage from the locking groove 13 during the movement of the locking component 3 driven by the top rod 22. The structure is simple and convenient for users to use and control. In this embodiment, the side wall of the base rod is provided with a movable groove 216. The locking rod 41 passes through the sliding groove and engages with the locking groove, and the locking rod 41 can slide in the sliding groove and disengage from the locking groove.

[0057] In this embodiment, the base plate 1 is provided with two sets of slots 13. When the locking rod 41 engages with the two sets of slots 13, the handlebar 2 and the base plate 1 are respectively kept in an unfolded state and a folded state. The two sets of slots 13 are connected by an arc-shaped surface or an arc-shaped groove 14. After the locking rod 41 is disengaged from the slot 13, the locking rod 41 can slide along the arc-shaped surface or an arc-shaped groove 14 and quickly engage with the slot 13. The setting of the two sets of slots 13 makes it easy for the handlebar 2 and the base plate 1 to keep in a folded state, which is convenient for the storage and transportation of the folding scooter. The setting of the arc-shaped surface or an arc-shaped groove 14 makes it easy for the locking rod 41 to switch between the two sets of slots 13. During the rotation of the handlebar 2 and the base plate 1, the user does not need to drive the top rod 22 all the time, which makes it convenient for the user to control the unfolding and folding of the folding scooter and make it convenient for the user to use. The two sets of slots 13 shown in the attached drawings of this utility model are connected by an arc-shaped groove 14.

[0058] The bottom rod 21 is provided with a sliding groove 211, and the top rod 22 is slidably disposed in the sliding groove 211. The side wall of the sliding groove 211 is provided with several positioning grooves 212 spaced apart along the extending direction of the sliding groove 211. The control component 6 includes a snap-fit ​​member 64 and a control member 61. The snap-fit ​​member 64 is disposed at the lower part of the top rod 22 and passes through the sliding groove 211. The control member 61 is located on the upper part of the top rod 22 or on the handle 23 and is disposed outside the sliding groove 211. A third elastic member 65 is disposed on the top rod 22, and the third elastic member 65 drives… The latching member 64 engages with the positioning groove 212 and fixes the top rod 22 and the bottom rod 21 relative to each other. The control member 61 can control the movement of the latching member 64 and disengage the latching member 64 from the positioning groove 212, thereby allowing the top rod 22 and the bottom rod 21 to slide relative to each other. In this structure, since the control member 61 is located on the top rod 22 or on the handle 23, the user can slide the top rod 22 and the bottom rod 21 relative to each other while controlling the control member 61 with one hand, which is convenient for the user to control the unfolding and folding of the folding scooter and is convenient for the user to use.

[0059] In this embodiment, a control port is provided at the upper end of the grip 23, and a control member 61 is slidably disposed in the control port. The movement direction of the control member 61 is inclined or perpendicular to the movement direction of the latching member 64. A connecting rod 62 is provided on the control member 61, and an inclined driving surface 621 is provided on the connecting rod 62. A mating surface 642 adapted to the driving surface 621 is provided on the latching member 64. By controlling the sliding of the control member 61, the driving surface 621 on the connecting rod 62 can drive the latching member 64 to move and disengage the latching member 64 from the latching slot 13. The control port at the upper end of the grip 23 makes it convenient for the user to control the control member 61, while the inclined driving surface 621 makes it convenient for the user to drive the latching member 64 to move through the control member 61. The structure is simple and convenient for the user to control the latching member 64.

[0060] Preferably, the top rod 22 is provided with a fourth elastic element 63. The fourth elastic element 63 can drive the control element 61 and the connecting rod 62 to reset and prevent the control element 61 from accidentally driving the latching element 64 to disengage from the slot 13. The fourth elastic element 63 can prevent the control element 61 from driving the latching element 64 to move under the action of gravity, prevent the latching element 64 from accidentally disengaging from the slot 13 during use, and prevent the top rod 22 and the bottom rod 21 from accidentally sliding during use. This is conducive to the stable installation of the top rod 22 and the bottom rod 21 and helps to improve the safety of the folding scooter.

[0061] In this embodiment, a fixed base 231 is fixedly provided in the top rod 22. The fixed base 231 is provided with a first groove 232 and a second groove 233. The connecting rod 62 and the snap-fit ​​member 64 are slidably provided in the first groove 232 and the second groove 233, respectively. The fourth elastic member 63 and the third elastic member 65 are respectively provided in the first groove 232 and the second groove 233, respectively. A guide block 234 is provided in the first groove 232. The connecting rod 62 is provided with a guide groove 622 that is adapted to the guide block 234. Both sides of the snap-fit ​​member 64 extend to form a protruding edge 641. A mating surface 642 is provided on the protruding edge 641. The connecting rod 62 extends from both sides of the guide block 234 into the second groove 233 and respectively cooperates with the mating surface 642.

[0062] To facilitate the driving of the connecting rod 62 by the control component 61, in this embodiment the control component 61 is connected to the connecting rod 62 by an extension rod 611. The snap-fit ​​component 64 is provided with a snap-fit ​​part 643 that matches the positioning groove 212 and a guide part 644 that matches the guide groove 622.

[0063] In this utility model, the base rod 21 is provided with a limiting member, and the transmission member 4 is provided with a limiting groove 43 that is adapted to the limiting rod. The limiting rod and the limiting groove 43 cooperate to limit the movement range of the transmission member 4, thereby preventing the transmission rod from passing through the base rod 21 and contacting the base plate 1. The setting of the limiting rod and the limiting groove 43 can limit the movement range of the transmission member 4, prevent the transmission rod from passing through the base rod 21 and contacting the base plate 1, and affect the relative rotation of the base rod 21 and the base plate 1, making it convenient for the user to control the relative rotation of the base rod 21 and the base plate 1.

[0064] In this embodiment, a limiting block 5 is provided in the slide 211, and a fixing rod 51 is provided on the limiting block 5. A first fixing hole 217 adapted to the fixing rod 51 is provided on the side wall of the slide 211. A receiving groove 44 is provided on the transmission member 4. The limiting block 5 and the second elastic member are both provided in the receiving groove 44. When the transmission member slides, the limiting block 5 slides in the receiving groove 44.

[0065] The transmission component 4 is provided with a driving part 42 for driving the locking component 3. The limiting groove 43 and the limiting component cooperate to prevent the driving part 42 from passing through the locking groove 215 and abutting against the base plate 1. The end of the locking component 3 or the end of the locking groove 215 is provided with a guide slope 34. After the locking component 3 drives the positioning component to move, it controls the bottom rod 21 and the base plate 1 to rotate. The positioning component can be guided by the guide slope 34 and pass through the locking groove 215. The setting of the guide slope 34 facilitates the engagement or disengagement of the locking component 3 and the locking groove 215, and facilitates the relative unfolding and folding of the handle 2 and the base plate 1 during use, making it convenient for the user.

[0066] The base rod 21 of this invention is provided with a deformable part 213 and a clamp 7. The clamp 7 has connecting parts 71 at both ends, which are connected by a drive rod 72. A cam 73 is rotatably mounted on the drive rod 72. By rotating the cam 73, the cam 73 can control the connecting parts 71 at both ends of the clamp 7 to move closer together and clamp the clamp 7 to hold the deformable part 213 tightly. This causes the deformable part 213 to press against the top rod 22, thereby limiting the relative sliding between the top rod 22 and the base rod 21. The deformable part 213, clamp 7, drive rod 72, and cam 73 are designed to further fix the base rod 21 and the top rod 22 relative to each other, preventing the base rod 21 and the top rod 22 from accidentally retracting during use.
