A scooter

Abstract

The application discloses a scooter, which comprises a bottom support, a handle, a connecting seat and a locking member pivotally connected to the bottom support. The lower end of the handle is connected to the connecting seat, and the connecting seat is relatively rotatably connected to the bottom support. The locking member is provided with an upwardly extending locking portion on one side. The connecting seat is provided with a first locking hole. When the locking member is rotated upward relative to the bottom support so that the locking portion extends into the first locking hole, the connecting seat cannot rotate relative to the bottom support, and the scooter is locked in an unfolded state. When the locking member is rotated downward relative to the bottom support so that the locking portion is separated from the first locking hole, the connecting seat can rotate relative to the bottom support, and the scooter can be folded. The structure for locking the scooter in the unfolded state is simple, and thus the cost of the scooter is relatively low. In addition, the unlocking operation is simple.

Description

Technical Field

[0001] This invention relates to the field of children's products, and more particularly to a scooter. Background Technology

[0002] Scooters are widely used because they are used by children for riding and playing. A scooter generally consists of a base and a handlebar. The base has a footboard, and wheels are located on the front and rear sides of the base. The handlebar is pivotally connected to the front of the base. To use it, the child stands on the footboard of the base, holds onto the handlebar, and rides.

[0003] Scooters are generally designed to be foldable, so that they can be folded up when they need to be transported or are not in use, allowing the rider to rotate relative to the base frame, thereby reducing the overall size of the scooter.

[0004] Currently, the scooters on the market have a complex structure that locks them in the unfolded state, making unlocking and folding operations cumbersome and increasing their cost, resulting in poor cost-effectiveness. Summary of the Invention

[0005] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a scooter that is easy to unlock and relatively inexpensive.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0007] A scooter that can switch between an unfolded state and a folded state includes a base and a rider. The scooter also includes a connecting seat, the lower end of which is connected to the connecting seat. The connecting seat and the base are rotatably connected relative to each other. The scooter also includes a locking member pivotally connected to the base. One side of the locking member has an upwardly extending locking portion, and the connecting seat has a first locking hole. When one side of the locking member rotates upward relative to the base until the locking portion extends into the first locking hole, the scooter is locked in the unfolded state. When one side of the locking member rotates downward relative to the base until the locking portion disengages from the first locking hole, the connecting seat can rotate relative to the base, and the scooter can be folded.

[0008] The scooter also includes an unlocking component, which is connected to the locking component. By driving the unlocking component, one side of the locking component can rotate up and down relative to the bottom support.

[0009] The unlocking element is movable or rotatable relative to the locking element.

[0010] The base support is provided with a first limiting member that can cooperate with the unlocking member. When the scooter is in the unfolded state, when the unlocking member cooperates with the first limiting member, the downward rotation of one side of the locking member relative to the base support is restricted. Moving or / or rotating the unlocking member relative to the locking member causes the unlocking member to disengage from the first limiting member, allowing one side of the unlocking member to rotate downward relative to the base support. Preferably, when the unlocking member at least partially abuts against the upper end surface of the first limiting member, the unlocking member cooperates with the first limiting member. Preferably, when the unlocking member is configured to move to one side and disengage from the first limiting member, the end face of that side of the first limiting member is configured as a slope inclined downward to that side.

[0011] The unlocking member is configured to move backward and downward to disengage from the first limiting member, and the upper end surface of the first limiting member is configured as a slope that slopes backward and downward; preferably, the rear end surface of the first limiting member is also configured as a slope that slopes backward and downward.

[0012] The base bracket is also provided with a second limiting member, and the second limiting member is configured such that when the locking member is rotated downward to abut against the second limiting member, the locking part of the locking member is in a state of disengaging from the first locking hole; preferably, when the locking member is rotated downward to abut against the upper end surface of the second limiting member, the locking part of the locking member is in a state of disengaging from the first locking hole; preferably, the second limiting member is provided on the front side of the first limiting member, and the upper end surface of the second limiting member is higher than the upper end surface of the first limiting member.

[0013] The scooter also includes an elastic reset member that can drive the unlocking member to reset relative to the locking member. The elastic reset member is disposed between the unlocking member and the bottom bracket or between the unlocking member and the locking member. Preferably, a torsion spring is also disposed between the unlocking member and the bottom bracket.

[0014] When the unlocking member is movably connected to the locking member relative to the left and right or back and forth, an elastic reset member is provided between the unlocking member and the locking member, and the elastic reset member is configured as a tension spring; or, the elastic reset member is provided between the unlocking member and the base bracket, and the reset member is configured as a compression spring; or, when the unlocking member is rotatably connected to the locking member, the unlocking member and the locking member are provided with the elastic reset member, and the elastic reset member is configured as a torsion spring.

[0015] The unlocking component is fixedly connected to the locking component, and a torsion spring is provided between the unlocking component and the base bracket.

[0016] The base bracket has an accommodating space, and the top wall of the accommodating space has a first through hole and a second through hole. The first locking hole is located on the lower end face of the connecting seat. The locking member is located in the accommodating space, and the rear side of the locking member is pivotally connected to the base bracket. The locking part is located on the front side of the locking member, and the upper side of the locking part can pass upward through the first through hole and extend into the first locking hole. The unlocking member is at least partially located at a position corresponding to the second through hole.

[0017] The unlocking component includes a connecting portion and an operating portion extending outward from one end of the connecting portion toward the second through hole. The connecting portion is connected to the locking component. Preferably, when the slide plate is in the unfolded state, the operating portion extends into the second through hole, and the end face of the connecting portion toward the second through hole abuts against the top wall of the accommodating space. Preferably, the elastic reset component is also disposed within the accommodating space.

[0018] A second locking hole is also provided on the lower end face of the connecting seat. The first locking hole and the second locking hole are spaced apart. When the scooter is in a folded state, the locking part of the locking member extends into the second locking hole. Preferably, when the scooter is in a folded state, the unlocking member and the first limiting member are in a cooperating state.

[0019] The lower end face of the connecting seat is configured as a first inclined surface that slopes downwards and backwards. Correspondingly, the surface of the base bracket facing the first inclined surface is configured as a second inclined surface that slopes downwards and backwards. The connecting seat can be rotatably connected to the base bracket via a connecting pin that is perpendicular to the first and second inclined surfaces. Preferably, the first locking hole and the second locking hole are symmetrically arranged about the connecting pin.

[0020] Because the scooter of this invention adopts the above-mentioned technical solution, the following beneficial technical effects can be achieved:

[0021] 1. The present invention has a simple structural design that locks the scooter in the unfolded state, thus the cost of the scooter is relatively low, and the unlocking operation is also simple;

[0022] 2. The above-mentioned unlocking mechanism, along with the elastic reset mechanism, makes the folding and unfolding of the scooter simpler.

[0023] 3. Because the relative surfaces of the connecting seat and the base bracket are both inclined downwards and backwards, and the first inclined surface and the second inclined surface are in contact when the frame is unfolded, this design not only allows the rotation of the connecting seat relative to the base bracket to reduce the angle between the two and fold the scooter, but also makes folding / operation simple.

[0024] 4. The first locking hole and the second locking hole are symmetrically arranged about the connecting pin, so that when the scooter is locked in the folded state, the angle between the rider and the base is minimized, which makes the folded scooter relatively smaller and thus more convenient to transport and store.

[0040] like Figures 1 to 9 As shown, this invention discloses a scooter that can switch between an unfolded state and a folded state. It includes a base frame 1 and a rider 2. The scooter also includes a connecting seat 3, with the lower end of the rider 2 connected to the connecting seat 3. The connecting seat 3 and the base frame 1 are rotatably connected, thus achieving the purpose of relative rotatable connection between the rider 2 and the base frame 1. The scooter also includes a locking member 4 pivotally connected to the base frame 1. One side of the locking member 4 has an upwardly extending locking portion 41, and the connecting seat 3 has a first locking hole 31. When one side of the locking member 4 rotates upward relative to the base frame 1 until the locking portion 41 extends into the first locking hole 31, the connecting seat 3 cannot rotate relative to the base frame 1, and the scooter is locked in the unfolded state. When one side of the locking member 4 rotates downward relative to the base frame 1 until the locking portion 41 disengages from the first locking hole 31, the connecting seat 3 can rotate relative to the base frame 1, and the scooter can be folded.

[0041] The scooter also includes an unlocking component 5, which is connected to the locking component 4. By driving the unlocking component 5, the locking component 4 can be rotated up and down relative to the bottom bracket 1, thereby enabling the locking part 41 to extend into or disengage from the first locking hole 3, thus achieving the locking and unlocking of the locking component 4.

[0042] In this embodiment, the unlocking member 5 is movable or rotatable relative to the locking member 4, and the unlocking member 5 can rotate relative to the bottom bracket 1 together with the locking member 4.

[0043] The base support 1 is provided with a first limiting member 14 that can cooperate with the unlocking member 5. When the scooter is in the unfolded state, when the unlocking member 5 cooperates with the first limiting member 14, the downward rotation of one side of the locking member 4 relative to the base support 1 is restricted. That is, the locking member 4 cannot rotate downward relative to the base support 1. In other words, when the scooter is in the unfolded state, because of the cooperation between the unlocking member 5 and the first limiting member 14, the unlocking member 5 cannot move downward, thus it cannot drive one side of the locking member 4 to rotate downward, and the locking part 41 cannot disengage from the first locking hole 31, thereby ensuring that the scooter is locked in the unfolded state. Moving or rotating the unlocking member 5 relative to the locking member 4 can disengage the unlocking member 5 from the first limiting member 14, and one side of the unlocking member 4 can rotate downward relative to the base support 1. At this time, the unlocking member 5 can drive the unlocking member 4 to rotate downward relative to the base support 1, thereby causing the locking part 41 to disengage from the first locking hole 31.

[0044] In this embodiment, when the unlocking member 5 at least partially abuts against the upper end surface 141 of the first limiting member 14, the unlocking member 5 cooperates with the first limiting member 15, and the unlocking member 5 cannot move downward, thereby preventing the locking member 4 from rotating downward, and thus the locking member 4 cannot rotate downward relative to the bottom bracket 1.

[0045] In this embodiment, the scooter is provided with two spaced-apart first limiting members 14. When the scooter is in the unfolded state, the locking member 4 is located on the upper side between the two first limiting members 14 or between the two first limiting members 14. This arrangement avoids interference with the rotation of the locking member 4, that is, avoids interference with the unfolding and folding of the scooter.

[0046] The scooter also includes an elastic reset member 6 that can drive the unlocking member 5 to reset. The elastic reset member 6 is disposed between the unlocking member 5 and the locking member 4 or between the unlocking member 5 and the bottom support 1.

[0047] In this embodiment, the base support 1 is provided with a receiving space 11, and the top wall of the receiving space 11 is provided with a first through hole 12 and a second through hole 13. The first locking hole 31 is provided on the lower end face 32 of the connecting seat 3. The locking member 4 is provided in the receiving space 11, and the rear side of the locking member 4 is pivotally connected to the base support 1. The locking part 41 is provided on the front side of the locking member 4, and the upper side of the locking part 41 passes through the first through hole 12 and extends into the first locking hole 31. The unlocking member 5 is at least partially located at the position corresponding to the second through hole 13, so as to facilitate the operator to operate the unlocking member 5.

[0048] The first limiting member 31 is disposed within the accommodating space and may be formed by extending upward from the bottom wall of the accommodating space 11.

[0049] The elastic reset member 6 is also located within the accommodating space 11, and is configured as a compression spring, positioned between the rear of the unlocking member 5 and the base bracket 1. This configuration ensures that when the scooter is in the unfolded state, only the unlocking member 5 is visible through the second through-hole 13; the elastic reset member 6 and the locking member 4 are not exposed, thus preventing damage that could affect the scooter's folding and unfolding operations.

[0050] The unlocking component 5 includes a connecting portion 51 and an operating portion 52 extending outward from one end of the connecting portion 51 toward the second through hole 13. The connecting portion 51 is connected to the locking component 4. Preferably, when the skateboard is in the unfolded state, the operating portion 52 extends into the second through hole 13, and the end face of the connecting portion 51 facing the second through hole 13 abuts against the top wall of the accommodating space 11. This arrangement better ensures that foreign objects cannot enter the accommodating space 11 through the second through hole 13, thereby further avoiding interference with the folding and unfolding operation of the scooter.

[0051] In this embodiment, the unlocking member 5 is movably connected to the locking member 4, and the unlocking member 5 is configured to move backward and downward to disengage from the first limiting member 14. Therefore, preferably, the upper end surface 141 of the first limiting member 14 is a sloped surface that tilts backward and downward. That is, by moving the unlocking member 5 backward and downward, the unlocking member 5 can disengage from the upper end surface of the first limiting member 14. At this time, pressing down on the unlocking member 5 can cause the unlocking member 4 to rotate downward relative to the bottom bracket 1.

[0052] Preferably, the unlocking member 5 is movably fitted onto the locking member 4, that is, the connecting part 51 is movably fitted onto the locking member 4. Preferably, the compression spring 6 is also fitted onto the locking member 4, that is, a through-hole 510 is provided in the connecting part 51, and the rear end of the locking member 4 passes through the through-hole 510 and the compression spring 6. This arrangement makes assembly more convenient.

[0053] In this embodiment, when the scooter is in the unfolded state, the lower end of the connecting part 51 may at least partially abut against the upper end surface 141 of the first limiting member 14.

[0054] To facilitate assembly, a pivot member 7 can be provided. During assembly, the rear end of the locking member 4 can be passed sequentially through the socket hole of the unlocking member 5 and the compression spring 6. Then, the rear end of the unlocking member 5 is inserted into the pivot groove 70 on the front side of the pivot member 7. The unlocking member 5 and the pivot member 7 are then connected by a pivot shaft, making the unlocking member 5 and the pivot member 7 pivotally connected. Finally, the pivot member 7 is fixedly connected within the accommodating space 11. In this way, it is equivalent to assembling the locking member 4, the unlocking member 5, the compression spring 6, and the pivot member 7 first. This assembly method makes assembly more convenient.

[0055] In other embodiments, the pivot 7 may be directly part of the base support 1.

[0056] In this embodiment, the base support 1 includes a base 15 and an upper cover 16 fixedly connected to the base 15. After the base 15 and the upper cover 16 are fixedly connected, the accommodating space 11 and the first through hole 12 and the second through hole 13 are formed. This further facilitates assembly.

[0057] Preferably, a second locking hole 33 is also provided on the lower end face 32 of the connecting seat 3. The first locking hole and the second locking hole 33 are spaced apart. When the scooter is in the folded state, the locking part 41 of the locking member 4 extends into the second locking hole 33, thereby locking the scooter in the folded state. This arrangement prevents the scooter from falling apart when it is being transported after being folded.

[0058] In this embodiment, the lower end face 32 of the connecting seat 3 is set as a first inclined surface that slopes downwards and backwards. Correspondingly, the surface of the base bracket 1 facing the first inclined surface is set as a second inclined surface 17 that slopes downwards and backwards. The connecting seat 3 can be rotatably connected to the base bracket 1 through a connecting pin 18 that is perpendicular to the first inclined surface 32 and the second inclined surface 17.

[0059] Preferably, the first inclined surface 32 and the second inclined surface 17 are configured such that when the scooter is in the unfolded state, the first inclined surface 32 and the second inclined surface 17 are in contact with each other.

[0060] Preferably, the first locking hole 31 and the second locking hole 33 are symmetrically arranged about the connecting pin 18.

[0061] Combination Figure 10 , 11 As shown, when the scooter is in the unfolded state, the rear end of the compression spring 6 abuts against the front side wall of the pivot member 7, the front end abuts against the rear end of the unlocking member 5, and the lower end of the unlocking member 5 abuts against the upper inclined surface 141 of the first limiting member 14. The locking part 41 on the front side of the locking member 4 passes through the first through hole 12 and extends into the first locking hole 31 of the connecting seat 3, so that the connecting seat 3 cannot rotate relative to the bottom bracket 1, and the scooter of the present invention is locked in the unfolded state.

[0062] like Figure 12 As shown, when folding the scooter of the present invention, simply move the unlocking member 5 backward and downward. The lower end of the unlocking member 5 will move backward and downward along the upper end surface 141 of the first limiting member 14, and the unlocking member 5 will also move backward and downward along the locking member 4 until the lower end of the unlocking member 5 disengages from the upper end surface 141 of the first limiting member 14. At this time, continue the above-mentioned movement of the unlocking member 5. Because of the downward movement, the unlocking member 5 can drive the front side of the locking member 4 to rotate and move downward together. After the locking member 4 rotates and moves until the locking part 41 on the front side disengages from the first locking hole 31 of the connecting seat 3, the connecting seat 3 can rotate relative to the bottom bracket 1. The unlocking member 5 can be released during the rotation process of the connecting seat 3 relative to the bottom bracket 1.

[0063] Specifically, after the locking part 41 on the front side of the locking member 4 disengages from the first locking hole 31 of the connecting seat 3, with the base bracket 1 relatively stationary, the rider 2 and / or the connecting seat 3 are directly rotated, causing the connecting seat 3 to rotate relative to the base bracket 1 around the connecting pin 18. Because the relative surfaces of the connecting seat 3 and the base bracket 1 are the first inclined surface 32 and the second inclined surface 17 that slope downwards and backwards, the angle between the rider 2 and the base bracket 1 decreases as the connecting seat 3 rotates relative to the base bracket 1 (e.g., ...). Figure 13 (As shown). When rotated to align the second locking hole 33 with the locking part 41 of the locking member 4, under the action of the elastic reset member 6, the unlocking member 5 is driven to automatically move forward relative to the locking member 4. When the unlocking member 5 moves to the point where its front end abuts against the rear end face of the first limiting member 14, the unlocking member 5 will move upward along the rear end face of the first limiting member 14 while moving forward, thereby driving the locking member 4 to move upward. When the front side of the locking member 4 rotates upward and its locking part 41 extends into the second locking hole 33, the scooter of the present invention is locked in a folded state (as shown). Figure 14 (As shown). At this time, the lower end of the locking member 4 also abuts against the upper inclined surface of the first limiting member 14 again. That is, when the scooter is in the folded state, the unlocking member 5 and the first limiting member 14 are in a cooperating state again, thereby locking the scooter in the folded state.

[0064] Preferably, the rear end face 142 of the first limiting member 14 is configured as a downwardly sloping surface, which better ensures that when the locking member 4 moves forward, it will move upward along the rear end face of the first limiting member 14 to the reset state. Preferably, a torsion spring can also be provided between the locking member 4 and the base bracket 1 to allow the locking member 4 to reset more effectively. The rear end face 142 of the first limiting member 14 can also be configured as a vertical surface, which will not affect the reset of the locking member 4.

[0065] In this embodiment, the elastic reset member 6 is configured as a compression spring and is disposed between the unlocking member 5 and the base bracket 1. In other embodiments, the elastic reset member 6 can also be configured as a compression spring and disposed between the unlocking member 5 and the locking member 4. When the locking member 4 is reset, the unlocking member 5 is pulled forward under the action of the tension spring. When the unlocking member 5 moves to the point where its front end abuts against the rear end face of the first limiting member 14, the unlocking member 5 will also move upward along the rear end face of the first limiting member 14 under the tension of the tension spring, thereby driving the side of the locking member 4 where the locking part 41 is disposed to move upward and reset.

[0066] In this embodiment, because the opposing surfaces of the connecting seat 3 and the base bracket 1 are both inclined downwards and backwards, forming a first inclined surface 32 and a second inclined surface 17, and the first inclined surface 32 and the second inclined surface 17 are in contact when the frame is in the unfolded state, this arrangement not only allows the rotation of the connecting seat 3 relative to the base bracket 1 to reduce the included angle between them, thus folding the scooter and simplifying folding / operation, but also ensures that when the scooter is in the unfolded state, the contacting first inclined surface 32 and the second inclined surface 17 eliminate the gap between the connecting seat 3 and the base bracket 1. This not only avoids the risk of pinching hands but also prevents foreign objects from entering between the first inclined surface 32 and the second inclined surface 17. The relative rotation between the connecting seat 3 and the base bracket 1 is affected, thereby avoiding any impact on the folding and unfolding of the scooter of the present invention. In addition, the first locking hole 31 and the second locking hole 33 are symmetrically arranged about the connecting pin 18, so that when the scooter is locked in the folded state, the first inclined surface 32 and the second inclined surface 17 will also be in a close fit. Thus, in the folded state, the danger of pinching hands and the prevention of foreign objects from entering between the first inclined surface 32 and the second inclined surface 17 can be avoided. Moreover, in the folded state, the angle between the rider 2 and the base bracket 1 is minimized, so that the folded scooter is relatively smaller in size, making it more convenient to transport and store.

[0067] Because the upper surface 141 of the first limiting member 14 is inclined, the unlocking member 5 moves more smoothly and easily downwards, making the unlocking operation of the locking member 4 simpler and easier. Furthermore, since the unlocking member 5 must be moved first to release its contact with the first limiting member 14 before the locking member 4 can be moved downwards, it's equivalent to adding a second safety lock before unlocking. This prevents accidental folding, thus making the scooter of this invention safer to use.

[0068] Preferably, the upper end of the operating part 52 of the unlocking member 5 is provided with a downwardly recessed operating groove 520, so that the operator can insert his / her finger into the operating groove 520 to move and press the unlocking member. This makes the operation more convenient.

[0069] Similarly, when unfolding the folded scooter, the unlocking member 5 needs to be moved backward and downward to disengage it from the first limiting member 14. Then, the unlocking member 5 is moved downward again, causing the locking part 41 of the locking member 4 to disengage from the second locking hole 33 of the connecting seat 3. The connecting seat 3 / handlebar 2 is then rotated, and the unlocking member 5 is released. When the first locking hole 31 aligns with the locking part 41 of the locking member 4, the locking part 41 of the locking member 4 re-enters the first locking hole 31 under the action of the elastic reset member 6, locking the scooter in the unfolded state. Therefore, unfolding the folding scooter is simple and easy.

[0070] Preferably, the base bracket 1 is provided with a second limiting member 10, and the second limiting member 10 is configured such that when the locking member 4 is rotated downwards to abut against the second limiting member 10, the locking part 41 of the locking member 4 is disengaged from the first locking hole 31. This configuration ensures that when the locking member 4 abuts against the upper surface of the second limiting member 10, it means that the locking member 4 can no longer rotate downwards. In other words, when the unlocking member 5 is pressed down until it can no longer be pressed, it means that the connecting seat 3 can rotate relative to the base 15. This configuration makes operation more intuitive and convenient. The second limiting member 10 is also disposed within the receiving hole 11.

[0071] In this embodiment, when the locking member 4 is rotated downwards to abut against the upper end face of the second limiting member 10, the locking part 41 of the locking member 4 is in a state of disengaging from the first locking hole 31.

[0072] The second limiting member 10 is disposed on the front side of the first limiting member 14, and the upper end surface of the second limiting member 10 is higher than the upper end surface 141 of the first limiting member 14.

[0073] In the above embodiment, the locking member includes a main body 42, the locking part 41 extends upward from the front end of the main body 42, and the unlocking member 5 is connected to the main body 42. When the scooter is in the unfolded state, the main body 42 is tilted downward and backward according to the shape of the corresponding part of the base bracket 1. Therefore, when unlocking, the unlocking member 5 needs to be moved downward and backward. If the shape of the relevant part of the base bracket 1 is modified to correspond to the shape of the main body 42, the shape of the upper end face 141 of the first limiting member can also be modified accordingly. For example, the unlocking member 5 can be disengaged from the first limiting member 14 simply by moving the unlocking member backward.

[0074] In other embodiments, the unlocking member 5 may be relatively movably connected to the locking member 4. However, when folding the scooter, the unlocking member moves forward and / or upward relative to the bottom support 1, so that the unlocking member 5 disengages from the first limiting member 14, and then drives the locking member 4 to rotate downward together. In this case, preferably, an elastic reset member can be provided between the unlocking member 5 and the locking member 4, and the elastic reset member can be a tension spring to assist the unlocking member in resetting; alternatively, the elastic reset member can be provided between the unlocking member 5 and the bottom support 1, and the elastic reset member can be a compression spring, the connection method of which can be any known and feasible method. During resetting, the rear side of the unlocking member 5 moves upward along the front end face of the first limiting member 14 to reset, the principle of which is the same as the aforementioned resetting of the unlocking member 5 moving backward and downward. Preferably, a torsion spring can also be provided between the locking member 4 and the bottom support 1 to assist the locking member 4 in resetting. In this embodiment, as Figure 15As shown, the unlocking member 5' may have a protruding abutment 511' on its lower side to the left and / or right. The abutment 511' abuts against the first limiting member 14, thus allowing the unlocking member 5 to move forward or / and upward, or backward or / and downward. Preferably, when moving the unlocking member forward or / and upward, space should be provided on the front side of the first limiting member 14 for the unlocking member 5 to move.

[0075] In another embodiment, the unlocking member 5 can be connected to the locking member 4 in a way that allows relative left-right movement. Similarly, an elastic reset member can be provided between the unlocking member 5 and the locking member 4, and this elastic reset member can be a tension spring; or, the elastic reset member can be provided between the unlocking member 5 and the bottom bracket 1, and the reset member can also be a compression spring to assist the unlocking member in resetting. Moving the unlocking member 5 to the left or right relative to the locking member 4 disengages the unlocking member 5 from the first limiting member 14, allowing the unlocking member 5 to be pressed down, thereby rotating the front side of the locking member 5 downwards and disengaging the locking part from the first locking hole 31. Preferably, a torsion spring can be provided between the locking member 4 and the bottom bracket 1 to assist the locking member 4 in resetting.

[0076] When the scooter is in the unfolded state, the left side of the unlocking member 5 abuts against the first limiting member 14. To fold the scooter, first move the unlocking member to the right until the left side of the unlocking member disengages from the first limiting member 14, then press down on the unlocking member 5, causing the locking member to rotate downwards. Similarly, if the right side of the unlocking member 5 abuts against the first limiting member 14 when the scooter is in the unfolded state, to fold the scooter, first move the unlocking member to the left until the right side of the unlocking member disengages from the first limiting member 14, then press down on the unlocking member 5, causing the locking member to rotate downwards. When the unlocking member 5 is configured to move relative to the left / right of the locking member, only one first limiting member needs to be set in the corresponding direction. If the unlocking member 5 moves to the left to disengage from the first limiting member 14, then the first limiting member 14 is positioned on the right side. Similarly, when the tension spring between the unlocking member 5 and the locking member 4 or the compression spring between the unlocking member 5 and the base bracket 1 acts, the unlocking member moves upward along the left end face of the first limiting member to reset. Preferably, the left end face of the first limiting member is set as a slope inclined downward to the left. That is, when the unlocking member 5 is set to move to one side to disengage from the first limiting member 14, the end face of the first limiting member 14 on that side is set as a slope inclined downward to that side.

[0077] In another embodiment (not shown), the unlocking member 5 can also be rotatably connected to the locking member 4, and the unlocking member 5 is configured such that, when the scooter is in the unfolded state, the unlocking member 5 at least partially abuts against the first limiting member 14; rotating the unlocking member 5 relative to the locking member 4 disengages the unlocking member 5 from the first limiting member 14. At this time, pressing down on the unlocking member will cause the locking member 4 to rotate downwards, thereby disengaging the locking part 41 from the first locking hole 31. Preferably, the unlocking member 5 and the locking member 4 are provided with an elastic reset member, and the elastic reset member can be a torsion spring to assist the unlocking member 5 in resetting. Further, a torsion spring is provided between the locking member 4 and the base bracket 1 to assist the locking member 4 in resetting.

[0078] In these embodiments, where the unlocking member 5 and the locking member 4 are relatively movable, the locking member 4 can be engaged by the socket 510. However, when moving left or right, the size of the socket 510 in the left-right direction must be appropriate to allow the unlocking member 5 to move left or right relative to the locking member 4. Where the unlocking member 5 and the locking member 4 are relatively rotatably connected, any known and feasible method can be used to connect them, as long as the above functions are achieved.

[0079] In the above embodiments, the shape of the second perforation 13 can be changed accordingly to accommodate various movements / rotations of the unlocking member.

[0080] The base support 1 is provided with a pedal structure 111, and a front wheel 100 is provided on the front side of the base support 1, and a rear wheel 200 is provided on the rear side. Other technologies are well-known and will not be described in detail here. The connection between the rider 2 and the connecting seat 3 can also be any known and feasible structure, and is not the inventive point of this invention, so it will not be described in detail here either.

[0081] As described above, the present invention achieves the unfolding and locking of the scooter by inserting the locking part 41 on the locking member 4 into the first locking hole 31; to unlock, the locking member is rotated downwards to release the lock. Thus, the structural design of the present invention for locking the scooter in the unfolded state is simple, resulting in a relatively low cost for the scooter and a simple folding operation. The present invention provides the aforementioned unlocking member 5 to assist in unlocking, and with the addition of the elastic reset member 6, the folding and unfolding operations are made even simpler. The first limiting member 14, along with its cooperation with the unlocking member 5, further ensures the stability of the scooter in the unfolded state.

[0082] The unlocking component 5 can also be fixedly connected to the locking component 4, and a torsion spring (not shown) is provided between the rear end of the unlocking component 4 and the bottom bracket 1, so that the locking part 41 always maintains an upward rotation trend. With this configuration, when the first locking hole / second locking hole is aligned with the locking part 41 without external force, the locking part 41 automatically rotates upward and extends into the first locking hole / second locking hole under the action of the torsion spring, thus making the unfolding / folding operation of the scooter simpler. Moreover, without external force, the locking part 41 will not disengage from the first locking hole / second locking hole, thereby maintaining the stability of the scooter in the unfolded / folded state. Similarly, in this embodiment, the unlocking component also includes a connecting part 51 and an operating part 52 extending outward from the end of the connecting part 51 toward the second through hole 13. The operating part 52 is fixedly connected to the locking component 4 or integrally formed with the locking component 4, and the cooperation between the end of the operating part 52 toward the second through hole 13 and the bottom wall of the accommodating space, and the cooperation between the operating part 52 and the second through hole 13, can be the same as the configuration of the above embodiment. Furthermore, in this embodiment, the first limiting member 14 and the elastic reset member 6 may not be provided.

[0083] The above definitions of up, down, front, back, left, and right directions are based on the normal usage scenario. That is, with a child standing on the base support 1 and holding onto the handlebars 2 while sliding, the front wheel is the front, the rear road is the back, the handlebars 2 are the top, the base support 1 is the bottom, and the two first limiting members 14 are the left and right.
