Description

Technical Field

[0001] The present invention relates to sports equipment, in particular to a steering mechanism of a scooter and the scooter. Background Art

[0002] Scooters are a type of sports equipment that is very suitable for children to play and relax. They have been popular in the market for a long time. Almost every child owns a scooter, which can reach a maximum speed of more than 20 kilometers per hour. The main components of a scooter include pedals and vertical rods. The existing mainstream scooters are usually three-wheeled structures with two sets of rollers in the front and a set of rollers in the back. When in use, the steering action is achieved by swinging the vertical rod left and right under the action of gravity.

[0003] This existing steering method is different from the steering operation of traditional bicycles, and beginners need to adapt. In addition, there are now scooters with seats, which the operator can sit on to operate the scooter. For scooters with seats, because the operator sits on the seat, it is more difficult to control the direction of the scooter by gravity (swaying left and right). Summary of the Invention

[0004] The present invention addresses the above-mentioned problems, overcomes at least one of the drawbacks, and provides a steering mechanism for a scooter and a scooter.

[0005] The technical solution adopted by the present invention is as follows:

[0006] A steering mechanism for a scooter, comprising a footboard and a vertical rod mounted on the footboard, two roller assemblies mounted at the front end of the footboard, each roller assembly comprising a roller frame and a roller mounted on the roller frame, the roller frame being rotatably engaged with the footboard, the roller frame having an extension rod, the scooter further comprising a connecting frame connecting the two roller frames, the ends of the connecting frame respectively rotatably engaged with corresponding extension rods, the connecting frame having a mating hole, the steering mechanism comprising:

[0007] A rotating member is rotatably mounted on the foot pedal, and the rotating member is mounted on the lower portion of the vertical rod. When the vertical rod is rotated, the rotating member can be driven to rotate;

[0008] a first transmission member rotatably mounted on the foot pedal, wherein one end of the first transmission member has a first driving portion extending into the matching hole, and the other end has a notch;

[0009] The second transmission member is installed on the rotating member. The second transmission member has a second driving part that cooperates with the recess. The rotation axis of the first transmission member is located between the first driving part and the second driving part. When the second driving part cooperates with the recess, the first transmission member is driven to rotate by the rotation of the rotating member, and the connecting frame is driven to move by the rotation of the first transmission member.

[0010] The phrase "the second transmission member is mounted on the transmission member" in this application includes the case where the second transmission member and the rotating member are integrally formed. The phrase "the rotating member is mounted on the lower portion of the vertical rod" in this application means that the rotating member is directly or indirectly (via other components) connected to the vertical rod.

[0011] The foot pedal, extension rod, and connecting frame form a four-bar linkage structure. By controlling the movement of the connecting frame, the extension rod can be rotated. The rotation of the extension rod also rotates the roller frame, ultimately achieving steering adjustment of the roller. The working principle of the steering mechanism of the present application is as follows: the vertical rod is controlled to rotate. The vertical rod rotation drives the rotation of the rotating member that cooperates with the rotation of the foot pedal. The rotating member drives the rotation of the second rotating member. Through the cooperation of the second drive unit and the recess, the first transmission member rotates around its own rotation axis. Through the cooperation of the first drive unit and the matching hole, the first transmission member drives the connecting frame to move (i.e., it can rotate the roller frame). Because the rotation axis of the first transmission member is located between the first drive unit and the second drive unit, when the vertical rod rotates to the left, the roller frame also rotates to the left, and when the vertical rod rotates to the right, the roller frame also rotates to the right. This structure of the present application can achieve an operating experience similar to the steering of a transmission bicycle. This steering operation method is particularly suitable for scooters equipped with a seat.

[0012] In one embodiment of the present invention, the first transmission member includes two limiting rods, and the two limiting rods form the notch.

[0013] In one embodiment of the present invention, the rotating member has a slide groove, the second transmission member is slidably arranged on the slide groove, the foot pedal has an anti-rotation block, the second transmission member has a first working position and a second working position, when the second transmission member is in the first working position, the second driving part is located at the recess, when the rotating member rotates, the second driving part can drive the first transmission member to rotate, when the second transmission member is in the second working position, the second driving part disengages from the recess, the second transmission member cooperates with the anti-rotation block, and the second rotating member cannot rotate left and right around its own axis.

[0014] The second transmission member can adjust its position relative to the slide slot, so that the steering mechanism of the present application can have two steering modes. When the second transmission member is in the first working position, the steering operation is similar to that of a traditional bicycle (steering operation is achieved by rotating the vertical rod). When the second transmission member is in the second working position, the second transmission member cooperates with the anti-rotation block, and the second rotating member cannot rotate left and right around its own axis, and the second transmission member no longer cooperates with the first transmission member. At this time, the vertical rod will not rotate, and the steering of the scooter is switched to steering by gravity.

[0015] In actual use, there are two anti-rotation blocks, and the second transmission member is located between the two anti-rotation blocks.

[0016] In one embodiment of the present invention, a locking structure is further included, wherein the locking structure is used to fix the second transmission member in a corresponding working position; the locking structure includes:

[0017] Two second arc-shaped grooves spaced apart from each other are provided on the second transmission member;

[0018] The second control member is rotatably mounted on the second transmission member. The second control member includes an eccentric portion and an operating portion. The eccentric portion of the second control member is used to cooperate with the second arc groove. The second control member has a locking working position and an unlocking working position. When the second control member is in the locking working position, the eccentric portion of the second control member is embedded in the corresponding second arc groove, and the second transmission member and the rotating member are relatively fixed. When the second control member is in the unlocking working position, the eccentric portion of the second control member is disengaged from the corresponding second arc groove, and the second transmission member can move relative to the slide groove.

[0019] The operating portion of the second control member is used to conveniently control the rotation of the second control member (by manually pulling the operating portion), thereby switching between the locked working position and the unlocked working position. This structure of the second control member can lock or unlock the second transmission member without tools.

[0020] In one embodiment of the present invention, the rotating member includes a first part and a second part, the first part is rotatably mounted on the foot pedal, the first part is used to connect with the vertical rod, the second part is fixed at the lower part of the first part, the slide groove is arranged in the second part, the second control member is rotatably mounted on the second part, and the second transmission member is located between the slide groove and the second control member.

[0021] The phrase "the first portion is connected to the vertical rod" in this application means that the first portion can be connected to the vertical rod directly or indirectly, such as through other components. In actual use, when the first portion is connected to the vertical rod through other components, the first portion and other components can be directly configured into a foldable structure.

[0022] In one embodiment of the present invention, a protective cover is installed under the foot pedal, and the connecting frame, rotating member, first transmission member, second transmission member and second control member are all located in the space formed by the protective cover and the foot pedal. The protective cover also has an operating port, which is used for the operator to operate the second control member and the second transmission member; the second transmission member has a push-pull portion that protrudes downward or is recessed inward.

[0023] Providing the push-pull portion can facilitate the control of movement of the second transmission member (when the second control member is in the unlocked working position), thereby facilitating switching of the working position of the second transmission member.

[0024] In one embodiment of the present invention, the matching hole is a strip hole, and the length direction of the strip hole is the same as the length direction of the pedal; the recess is a strip recess, and the length direction of the strip recess is the same as the length direction of the pedal.

[0025] In one embodiment of the present invention, the upper end of the vertical rod has a handlebar; the foot pedal, two extension rods and the connecting frame form a four-bar linkage; the scooter also includes a return torsion spring installed on the connecting frame and the foot pedal, and the return torsion spring is used to provide force to reset the connecting frame.

[0026] The present application also discloses a scooter, comprising the steering mechanism described above, and a seat mechanism, wherein the seat mechanism comprises:

[0027] A limiting member is externally mounted on the vertical rod, and the limiting member is installed on the vertical rod or on the foot pedal;

[0028] The mounting member includes a first body, the first body having two limiting arms, the limiting arms having a first limiting structure at one end away from the first body, the mounting member being sheathed on the limiting member through a space formed by the two limiting arms, and the limiting member being used to support the mounting member;

[0029] The anti-slip member includes a second body, the second body has two positioning parts, the positioning part has a second limiting structure that cooperates with the corresponding first limiting structure, the anti-slip member is used to vertically insert the mounting member, the second limiting structure cooperates with the first limiting structure to prevent the mounting member from detaching from the limiting member, after the anti-slip member is inserted into the mounting member, the anti-slip member and the mounting member form a limiting space that cooperates with the limiting member, when the anti-slip member vertically detaches from the mounting member, the mounting member can detach from the limiting member and the vertical rod;

[0030] A seat cushion has one end mounted on the mounting piece.

[0031] The vertical rod mentioned in this application refers to the vertical state when in use. In actual use, a folding structure can also be provided, and the vertical rod can be folded when it needs to be folded.

[0032] It should be noted that the phrase "the position limiting member is mounted on the vertical rod or the foot pedal" in this application also includes the situation where the position limiting member is mounted on both the vertical rod and the foot pedal. In addition, the position limiting member can be fixedly mounted on the vertical rod or the foot pedal, or it can be detachably mounted on the vertical rod or the foot pedal.

[0033] The seat cushion mechanism of the present application enables the mounting member to be restrained on the limiting member through the cooperation between the mounting member and the anti-slip member. When the seat cushion is no longer needed, the anti-slip member can be removed first, so that the anti-slip member is vertically separated from the mounting member. In this state, the two limiting arms of the mounting member can be separated from the limiting member and the vertical rod, that is, the mounting member with the seat cushion installed can be easily separated. This structure of the present application makes it relatively convenient to disassemble and assemble the seat cushion.

[0034] In one embodiment of the present invention, the first limiting structure is a limiting groove, and the second limiting structure is a limiting block; or, the first limiting structure is a limiting block, and the second limiting structure is a limiting groove.

[0035] The first limiting structure and the second limiting structure cooperate with each other so that the anti-slip part and the mounting part will not separate horizontally from each other. The anti-slip part and the mounting part form a limiting space that cooperates with the limiting part, ensuring reliable cooperation between the mounting part and the limiting part.

[0036] In one embodiment of the present invention, the position-limiting member has a positioning block, and the mounting member has a positioning groove that cooperates with the positioning block, or the position-limiting member has a positioning groove, and the mounting member has a positioning block that cooperates with the positioning groove;

[0037] The positioning block and the positioning groove cooperate with each other so that the limiting member supports the mounting member.

[0038] The positioning block and the positioning groove cooperate with each other to facilitate the positioning of the mounting piece, so that the anti-dropping piece can be easily inserted into the mounting piece, cooperate with the mounting piece, and be sheathed on the limiting piece. In addition, the positioning block and the positioning groove cooperate to enable the limiting piece to reliably support the mounting piece.

[0039] In one embodiment of the present invention, the first body has a first groove, and the limiting member has a first protrusion that matches the first groove.

[0040] The first groove and the first protrusion cooperate with each other, which can not only assist in positioning, but also relatively fix the mounting member and the limiting member in the circumferential direction, thereby enhancing the torque bearing capacity of the positioning block and the positioning groove.

[0041] In one embodiment of the present invention, the limiting member has a first arc-shaped groove, and the second body has a first opening, and the first opening corresponds to the first arc-shaped groove; a first control member is rotatably mounted on the second body, and the first control member includes an eccentric portion and an operating portion, and the eccentric portion of the first control member is used to cooperate with the first arc-shaped groove; the first control member has a locking working position and an unlocking working position, and when the first control member is in the locking working position, the eccentric portion of the first control member is embedded in the first arc-shaped groove, and the anti-slip member and the limiting member are relatively fixed, and when the first control member is in the unlocking working position, the eccentric portion of the first control member is disengaged from the first arc-shaped groove, and the anti-slip member can be disengaged from the mounting member.

[0042] The operating portion of the first control member is used to conveniently control the rotation of the first control member (by manually pulling the operating portion), thereby switching between the locked and unlocked working positions. This structural form of the first control member allows the removal of the anti-dropping member and the installation member without tools, which is convenient to operate.

[0043] In one embodiment of the present invention, the second body has a second groove, the limiting member has a second protrusion that cooperates with the second groove, the first arc groove is provided on the second protrusion, and the first opening passes through the second groove.

[0044] The second groove and the second protrusion cooperate with each other, which can not only assist in positioning, but also relatively fix the mounting member and the limiting member in the circumferential direction, thereby enhancing the torque bearing capacity of the positioning block and the positioning groove.

[0045] In one embodiment of the present invention, there is a slot on the foot pedal, and the limiting component includes two parts, each of which includes a matching part that matches the vertical rod and an extension part connected to the matching part. The lower end of the extension part is inserted into the corresponding slot, and the matching parts of the two parts match each other and are sheathed on the vertical rod; the limiting space matches the two matching parts.

[0046] This structural design of the retaining member allows the mounting member and the anti-slip member to form a space that reliably holds the two mating parts in place, creating a clever structure. To remove the seat, the anti-slip member can be removed first, followed by the mounting member and seat being separated from the retaining member. Finally, the retaining member can be pulled away from the footrest. This structure allows for comprehensive removal of all seat-related components, making the scooter more compact.

[0047] In one embodiment of the present invention, the foot pedal has a slot, and the seat mechanism also includes a support frame, one end of the support frame is rotatably mounted on the bottom of the seat, and the other end is used to be inserted into the slot; the end of the support frame that rotates with the seat is away from the vertical rod.

[0048] The cooperation between the card slot and the support frame can ensure that the seat cushion is reliably stressed.

[0049] In one embodiment of the present invention, the seat cushion is rotatably mounted on the first body, and a receiving groove is provided at the bottom of the seat cushion. The receiving groove is used to cooperate with the support frame and to allow the support frame to be inserted when the support frame is folded.

[0050] The receiving groove is provided to facilitate the folding of the support frame; the seat cushion is rotatably mounted on the first body, so that the seat cushion of the present application can also be folded vertically like a traditional structure.

[0051] The beneficial effects of the present invention are as follows: the foot pedal, extension rod, and connecting frame form a four-bar linkage structure. By controlling the movement of the connecting frame, the extension rod can be rotated. The rotation of the extension rod also rotates the roller frame, ultimately achieving steering adjustment of the roller. The working principle of the steering mechanism of the present application is as follows: the vertical rod is controlled to rotate, and the vertical rod rotation drives the rotation of the rotating member that cooperates with the rotation of the foot pedal. The rotating member drives the rotation of the second rotating member. Through the cooperation of the second drive unit and the recess, the first transmission member rotates about its own rotation axis. Through the cooperation of the first drive unit and the matching hole, the first transmission member drives the connecting frame to move (i.e., it can rotate the roller frame). Because the rotation axis of the first transmission member is located between the first drive unit and the second drive unit, when the vertical rod rotates to the left, the roller frame also rotates to the left, and when the vertical rod rotates to the right, the roller frame also rotates to the right. This structure of the present application can achieve an operating experience similar to the steering of a transmission bicycle. This steering operation method is particularly suitable for scooters equipped with a seat. BRIEF DESCRIPTION OF THE DRAWINGS

[0066] The present invention will be described in detail below with reference to the accompanying drawings.

[0067] like Figure 1 、 4 As shown in Figures 6 and 8, this embodiment discloses a scooter, which includes a footboard 1 and a vertical rod 2 installed on the footboard 1. The scooter also includes a steering mechanism and a seat mechanism. Figure 1 、 2 As shown in , 3, 4 and 5, the cushion mechanism of this embodiment includes:

[0068] The limiting member 4 is externally mounted on the vertical rod 2;

[0069] The mounting member 5 includes a first body 8 having two limiting arms 9 on the first body 8. The limiting arm 9 has a first limiting structure 10 at one end away from the first body 8. The mounting member 5 is sheathed on the limiting member 4 through the space formed by the two limiting arms 9. The limiting member 4 is used to support the mounting member 5.

[0070] The anti-slip member 6 includes a second body 11, and the second body 11 has two positioning portions 12. The positioning portion 12 has a second limiting structure 13 that cooperates with the corresponding first limiting structure 10. The anti-slip member 6 is used to vertically insert the mounting member 5. The second limiting structure 13 cooperates with the first limiting structure 10 to prevent the mounting member 5 from detaching from the limiting member 4. After the anti-slip member 6 is inserted into the mounting member 5, the anti-slip member 6 and the mounting member 5 form a limiting space 7 that cooperates with the limiting member 4. When the anti-slip member 6 vertically detaches from the mounting member 5, the mounting member 5 can detach from the limiting member 4 and the vertical rod 2;

[0071] One end of the seat cushion 14 is mounted on the mounting member 5 .

[0072] The vertical rod 2 mentioned in this application refers to the vertical state when in use. In actual use, a folding structure can also be provided, and the vertical rod 2 can be folded when it needs to be folded.

[0073] It should be noted that, in actual use, the limiter 4 can be installed on the vertical rod 2 and / or on the foot pedal 1. Specifically, the limiter 4 can be fixedly installed on the vertical rod 2 or the foot pedal 1, or can be detachably installed on the vertical rod 2 or the foot pedal 1.

[0074] The seat cushion mechanism of the present application cooperates with the mounting member 5 and the anti-slip member 6, so that the mounting member 5 can be restricted on the limiting member 4. When the seat cushion 14 is no longer needed, the anti-slip member 6 can be removed first, so that the anti-slip member 6 is vertically separated from the mounting member 5. In this state, the two limiting arms 9 of the mounting member 5 can be separated from the limiting member 4 and the vertical rod 2, that is, the mounting member 5 with the seat cushion 14 installed can be easily separated. This structure of the present application makes it relatively convenient to disassemble and install the seat cushion 14.

[0075] like Figure 2 、 3 As shown in Figures 5 and 6 , in this embodiment, the first limiting structure 10 is a limiting block, and the second limiting structure 13 is a limiting groove. In other embodiments, the first limiting structure 10 may be a limiting groove, and the second limiting structure 13 may be a limiting block. The first limiting structure 10 and the second limiting structure 13 cooperate with each other to prevent the anti-slip member 6 and the mounting member 5 from horizontally separating from each other. The anti-slip member 6 and the mounting member 5 form a limiting space 7 that cooperates with the limiting member 4, ensuring reliable cooperation between the mounting member 5 and the limiting member 4.

[0076] like Figure 2 、 3As shown in Figures 5 and 6 , in this embodiment, the limiting member 4 has a positioning block 15, and the mounting member 5 has a positioning groove 16 that cooperates with the positioning block 15. The positioning block 15 and the positioning groove 16 cooperate with each other, allowing the limiting member 4 to support the mounting member 5. The positioning block 15 and the positioning groove 16 cooperate with each other to facilitate the positioning of the mounting member 5, thereby allowing the anti-slip member 6 to be easily inserted into the mounting member 5, cooperate with the mounting member 5, and be externally mounted on the limiting member 4. In addition, the cooperation between the positioning block 15 and the positioning groove 16 can also enable the limiting member 4 to reliably support the mounting member 5. In other embodiments, the limiting member 4 can be provided with a positioning groove, and the mounting member 5 can be provided with a positioning block that cooperates with the positioning groove.

[0077] like Figure 2 、 3 As shown in Figures 5 and 6, in this embodiment, the first body 8 has a first groove 17, and the stopper 4 has a first protrusion 18 that cooperates with the first groove 17. The first groove 17 and the first protrusion 18 cooperate with each other to assist in positioning and to relatively fix the mounting member 5 and the stopper 4 in the circumferential direction, thereby enhancing the torque bearing capacity of the positioning block 15 and the positioning groove 16.

[0078] like Figure 2 、 3 As shown in Figure 5, in this embodiment, the limiting member 4 has a first arcuate groove 19, and the second body 11 has a first opening 20, and the first opening 20 corresponds to the first arcuate groove 19; a first control member 21 is rotatably mounted on the second body 11, and the first control member 21 includes an eccentric portion 22 and an operating portion 23, and the eccentric portion 22 of the first control member 21 is used to cooperate with the first arcuate groove 19; the first control member 21 has a locking working position and an unlocking working position. When the first control member 21 is in the locking working position, the eccentric portion 22 of the first control member 21 is embedded in the first arcuate groove 19, and the anti-slip member 6 is relatively fixed to the limiting member 4. When the first control member 21 is in the unlocking working position, the eccentric portion 22 of the first control member 21 is disengaged from the first arcuate groove 19, and the anti-slip member 6 can be disengaged from the mounting member 5.

[0079] The operating portion 23 of the first control member 21 is used to conveniently control the rotation of the first control member 21 (by manually pulling the operating portion 23), thereby switching between the locked and unlocked working positions. This structure of the first control member 21 allows the anti-drop member 6 and the mounting member 5 to be removed without tools, which is convenient for operation.

[0080] like Figure 2 、 3As shown in Figures 5 and 6, in this embodiment, the second body 11 has a second groove 24, the stopper 4 has a second protrusion 25 that cooperates with the second groove 24, the first arcuate groove 19 is provided on the second protrusion 25, and the first opening 20 extends through the second groove 24. The second groove 24 and the second protrusion 25 cooperate with each other to assist in positioning and to relatively fix the mounting member 5 and the stopper 4 in the circumferential direction, thereby enhancing the torque bearing capacity of the positioning block 15 and the positioning groove 16.

[0081] like Figure 3 and 5 As shown, in this embodiment, the limiter is detachably mounted on the footrest. Specifically, the footrest 1 has a slot 26, and the limiter 4 includes two sub-components 27. The sub-component 27 includes a mating portion 28 that mates with the vertical rod 2 and an extension 29 connected to the mating portion 28. The lower end of the extension 29 is inserted into the corresponding slot 26. The mating portions 28 of the two sub-components 27 mate with each other and are sheathed on the vertical rod 2. The limiter space 7 mates with the two mating portions 28. With this structural design of the limiter 4, the limiter space 7 formed by the mounting member 5 and the anti-slip member 6 can reliably confine the two mating portions 28, and the structure is ingenious. When the seat 14 needs to be removed, the anti-slip member 6 can be removed first, and then the mounting member 5 and the seat 14 can be separated from the limiter 4. Finally, the limiter 4 can be pulled out of the footrest 1. This structure allows for a relatively comprehensive removal of the structure related to the seat 14, making the scooter more concise.

[0082] like Figure 1 and 5 As shown, in this embodiment, the footrest 1 has a slot 30, and the seat mechanism also includes a support frame 31. One end of the support frame 31 is rotatably mounted on the bottom of the seat 14, and the other end is adapted to engage with the slot 30. The end of the support frame 31, which is rotatably engaged with the seat 14, is away from the vertical rod 2. The cooperation between the slot 30 and the support frame 31 ensures that the seat 14 is reliably supported.

[0083] like Figure 4 As shown, in this embodiment, the seat cushion 14 is rotatably mounted on the first body 8. The bottom of the seat cushion 14 has a receiving groove 32, which is used to cooperate with the support frame 31 and allow the support frame 31 to be snapped into place when the support frame 31 is folded. The provision of the receiving groove 32 facilitates the folding of the support frame 31. The seat cushion 14 is rotatably mounted on the first body 8, so that the seat cushion 14 of the present application can also be vertically folded like a traditional structure.

[0084] like Figure 6 、 7As shown in Figures 8 and 9, the front end of the pedal board 1 of the scooter of this embodiment is equipped with two roller groups 33. Each roller group 33 includes a roller frame 34 and a roller 35 mounted on the roller frame 34. The roller frame 34 is rotatably matched with the pedal board 1. The roller frame 34 has an extension rod 36. The scooter also includes a connecting frame 37 connecting the two roller frames 34. The two ends of the connecting frame 37 are rotatably matched with the corresponding extension rod 36. The connecting frame 37 has a matching hole 38. Figure 7 、 9 , 10, 11, and 12, the steering mechanism includes:

[0085] The rotating member 39 is rotatably mounted on the foot pedal 1. The rotating member 39 is mounted on the lower portion of the vertical rod 2. When the vertical rod 2 is rotated, the rotating member 39 can be driven to rotate.

[0086] A first transmission member 40 is rotatably mounted on the foot pedal 1. One end of the first transmission member 40 has a first driving portion 41 extending into the matching hole 38, and the other end has a notch 42;

[0087] The second transmission member 43 is installed on the rotating member 39. The second transmission member 43 has a second driving part 44 that cooperates with the recess 42. The rotation axis of the first transmission member 40 is located between the first driving part 41 and the second driving part 44. When the second driving part 44 cooperates with the recess 42, the rotation of the rotating member 39 drives the first transmission member 40 to rotate, and the rotation of the first transmission member 40 drives the connecting frame 37 to move.

[0088] The phrase “the rotating member 39 is installed at the lower portion of the vertical rod 2 ” mentioned in the present application means that the rotating member 39 is directly or indirectly (through other components) connected to the vertical rod 2 .

[0089] The foot pedal 1, extension rod 36, and connecting frame 37 form a four-bar linkage. By controlling the movement of connecting frame 37, the extension rod 36 can be rotated. The rotation of the extension rod 36 also rotates the roller frame 34, ultimately achieving steering adjustment of the roller 35. The operating principle of the steering mechanism of this application is as follows: Controlling the rotation of the vertical rod 2 drives the rotation of the rotating member 39 that rotates with the foot pedal 1. The rotating member 39 drives the rotation of the second rotating member 39. Through the cooperation of the second driving portion 44 and the recess 42, the first transmission member 40 rotates about its own rotation axis. Through the cooperation of the first driving portion 41 and the matching hole 38, the first transmission member 40 drives the connecting frame 37 (i.e., rotating the roller frame 34). Because the rotation axis of the first transmission member 40 is located between the first driving portion 41 and the second driving portion 44, when the vertical rod 2 rotates to the left, the roller frame 34 also rotates to the left, and when the vertical rod 2 rotates to the right, the roller frame 34 also rotates to the right. This structure of the application can achieve an operating experience similar to the steering of a transmission bicycle. This steering operation mode is particularly suitable for a scooter with a seat cushion 14 installed.

[0090] like Figure 7 、 9 As shown in Figures 10, 11, and 12, in this embodiment, the first transmission member 40 includes two limiting rods 45, and the two limiting rods 45 form a recess 42.

[0091] like Figure 7 、 9 , 10, 11, and 12, in this embodiment, the rotating member 39 has a slide groove 46, the second transmission member 43 is slidably set on the slide groove 46, the foot pedal 1 has an anti-rotation block 54, the second transmission member 43 has a first working position and a second working position, when the second transmission member 43 is in the first working position, the second driving part 44 is located at the recess 42, when the rotating member 39 rotates, the second driving part 44 can drive the first transmission member 40 to rotate, when the second transmission member 43 is in the second working position, the second driving part 44 is disengaged from the recess 42, the second transmission member 43 cooperates with the anti-rotation block 54, and the second rotating member 39 cannot rotate left and right around its own axis.

[0092] The second transmission member 43 can adjust its position relative to the slide groove 46, so that the steering mechanism of the present application can have two steering modes. When the second transmission member 43 is in the first working position, the steering operation is similar to that of a traditional bicycle (steering operation is achieved by rotating the vertical rod 2). When the second transmission member 43 is in the second working position, the second transmission member 43 cooperates with the anti-rotation block 54, the second rotating member 39 cannot rotate left and right around its own axis, and the second transmission member 43 no longer cooperates with the first transmission member 40. At this time, the vertical rod 2 will not rotate, and the steering of the scooter is switched to steering by gravity.

[0093] In actual use, the second transmission member 43 and the rotating member 39 can be an integrated member, that is, there is only one steering mode.

[0094] like Figure 7 and 9 As shown, there are two anti-rotation blocks 54 , and the second transmission member 43 is located between the two anti-rotation blocks 54 .

[0095] like Figure 9 and 12 As shown, in this embodiment, a locking structure is further included, which is used to fix the second transmission member 43 in the corresponding working position; the locking structure includes:

[0096] Two second arc-shaped grooves 47 spaced apart from each other are provided on the second transmission member 43;

[0097] The second control member 48 is rotatably mounted on the second transmission member 43. The second control member 48 includes an eccentric portion 22 and an operating portion 23. The eccentric portion 22 of the second control member 48 is used to cooperate with the second arc groove 47; the second control member 48 has a locking working position and an unlocking working position. When the second control member 48 is in the locking working position, the eccentric portion 22 of the second control member 48 is embedded in the corresponding second arc groove 47, and the second transmission member 43 is relatively fixed to the rotating member 39. When the second control member 48 is in the unlocking working position, the eccentric portion 22 of the second control member 48 is disengaged from the corresponding second arc groove 47, and the second transmission member 43 can move relative to the slide groove 46.

[0098] The operating portion 23 of the second control member 48 is used to conveniently control the rotation of the second control member 48 (by manually pulling the operating portion 23), thereby switching between a locked and unlocked working position. This structure of the second control member 48 can lock or unlock the second transmission member 43 without tools.

[0099] like Figure 10 、 11 As shown in Figures 12 and 12, in this embodiment, the rotating member 39 includes a first portion 49 and a second portion 50. The first portion 49 is rotatably mounted on the footrest 1 (in actual use, the friction between the first portion 49 and the footrest can be reduced by a bearing). The first portion 49 is used to connect to the vertical rod 2. The second portion 50 is fixed to the lower portion of the first portion 49. The slide 46 is provided in the second portion 50. The second control member 48 is rotatably mounted on the second portion 50. The second transmission member 43 is located between the slide 46 and the second control member 48. The phrase "the first portion 49 is connected to the vertical rod 2" in this application means that the first portion 49 can be directly connected to the vertical rod 2 or indirectly connected to the vertical rod 2, such as through other components. In actual use, when the first portion 49 is connected to the vertical rod 2 through other components, the first portion 49 and the other components can be directly configured as a foldable structure.

[0100] like Figure 4 and 6 As shown, in this embodiment, a protective cover 51 is installed below the footrest 1. The connecting frame 37, rotating member 39, first transmission member 40, second transmission member 43, and second control member 48 are all located in the space formed by the protective cover 51 and the footrest 1. The protective cover 51 also has an operating port 52 for allowing an operator to operate the second control member 48 and the second transmission member 43. The second transmission member 43 has a push-pull portion 53 that protrudes downward or is recessed inward. The push-pull portion 53 facilitates the control of the movement of the second transmission member 43 (when the second control member 48 is in the unlocked working position) and facilitates switching the working position of the second transmission member 43.

[0101] like Figure 7As shown, in this embodiment, the matching hole 38 is a strip hole, and the length direction of the strip hole is the same as the length direction of the pedal 1; the recess 42 is a strip recess 42, and the length direction of the strip recess 42 is the same as the length direction of the pedal 1.

[0102] like Figure 1 、 4 As shown in Figures 7, 9, 10, 11, and 12, in this embodiment, the upper end of the vertical rod 2 has a handlebar rod 3; the foot pedal 1, two extension rods 36 and the connecting frame 37 form a four-bar linkage; the scooter also includes a reset torsion spring 55 installed on the connecting frame 37 and the foot pedal 1, and the reset torsion spring 55 is used to provide force to reset the connecting frame 37.

[0103] The above description is only a preferred embodiment of the present invention and does not limit the scope of patent protection of the present invention. Any equivalent structural transformation made by using the contents of the description and drawings of the present invention, directly or indirectly applied to other related technical fields, is also included in the scope of protection of the present invention.
