[0002] Most of the existing scooters are provided with a seat board. In the state where the seat board is retracted, children can stand on the scooter and ride it as a scooter; in the state where the seat board is opened, children can sit on the seat board and slide by pedaling with their feet on the ground. At this time, the scooter is used as an assisted vehicle. However, due to the structure and usage characteristics of the scooter itself, the handle cannot be turned during use. The scooter mainly relies on the change of the rider's body center of gravity to achieve turning. This results in the inability to turn the vehicle when the scooter is converted into an assisted vehicle, and children cannot change the sliding direction as needed during use, reducing the fun of use.

[0045] The technical solution of the present invention will be further elaborated below in conjunction with the attached drawings and specific embodiments.

[0046] See Figures 1 to 16 A multifunctional scooter as shown. The scooter includes a joystick assembly 1, a main frame 2, a front wheel assembly 3 provided at the front of the main frame 2, and a rear wheel assembly 4 provided at the rear of the main frame 2. The joystick assembly 1 includes a joystick 11 extending in the vertical direction and a handlebar 12 provided on the joystick 11. The handlebar 12 is arranged to be height-adjustable relative to the joystick 11 to meet the usage needs of children of different heights. The front wheel assembly 3 includes a front wheel seat 31 and a front wheel 32 rotatably provided on the front wheel seat 31 around a front wheel shaft 33 extending in the left-right direction. The front wheel 32 has two groups respectively provided at the left and right ends of the front wheel seat 31. The rear wheel assembly 4 has a set of rear wheels 41 provided at the rear of the main frame 2. The main frame 2 includes a pedal 21 for stepping on and a mounting seat 22 fixed to the front of the pedal 21. The joystick 11 is rotatably connected to the mounting seat 22 relative to its own axis.

[0047] The scooter further includes a rotating base 6 provided between the mounting seat 22 and the front wheel seat 31. The front wheel seat 31 is rotatably connected to the rotating base 6 around a first shaft 101, and the rotating base 6 is rotatably connected to the mounting seat 22 around a second shaft 102. Among them, the first shaft 101 extends obliquely in the front-rear direction, specifically extending gradually backward from top to bottom; the axis of the second shaft 102 extends in the vertical direction, and the axis of the second shaft 102 is parallel to the axis of the joystick 11. The joystick 11 and the rotating base 6 are connected to be rotatable synchronously. A locking mechanism is also provided on the scooter. The locking mechanism has a first locking state that locks the mounting seat 22 and the rotating base 6 to each other, and a second locking state that locks the rotating base 6 and the front wheel seat 31 to each other.

[0048] The scooter has a first and second switchable state during use. When the scooter is in the first state, the locking mechanism is in the first lock state. The joystick 11 is fixed relative to the main frame 2, and the front wheel seat 31 can only rotate relative to the rotating base 6 about the inclined first axis 101. In this state, the joystick 11 cannot be used to control the steering of the front wheel assembly 3. The user can only steer the scooter by shifting their body weight to cause a change in their center of gravity. In other words, the first state is primarily used for conventional scooter gliding. When the scooter is in the second state, the locking mechanism is in the second lock state. The joystick 11 can rotate relative to the main frame 2 about its own axis and control the steering of the front wheel assembly 3. Specifically, rotation of the joystick 11 causes the rotating base 6 and the front wheel seat 31 to rotate synchronously about the second axis 102, enabling the entire front wheel assembly 3 to steer. The second state is primarily used for the scooter to be used as a scooter for riding.

[0049] As shown in the drawings, the scooter further includes a seat assembly 5, which includes a seat plate base 51 and a seat plate 52 rotatably disposed on the seat plate base 51. The seat plate 52 has a stowed state in which it is retracted relative to the operating lever 11, and an open state in which it extends in the front-to-back direction and is located above the pedal 21. The scooter is in a first use state, as shown in FIG. Figure 3 As shown, the seat plate 52 is in the retracted state. At this time, the scooter is used as a conventional children's scooter for children to step on and slide. When the scooter is in the second use state, as shown in FIG. Figure 1 、 Figure 2 As shown, the seat plate 52 is in the open position, allowing a child to sit or stand on the seat plate 52. In this case, the scooter serves as a child-assist vehicle for the child to sit or ride. In this embodiment, one end of the seat plate 52 is connected to the seat plate base 51 about a rotation axis 53 extending in the left-right direction. The seat plate 52 is flipped up and down about the rotation axis 53 to switch between the open position and the stowed position. In the stowed position, the seat plate 52 flips upward to extend in the vertical direction and retracts with the joystick 11.

[0050] In this embodiment, when the seat plate 52 switches between the above-mentioned open state and the retracted state, the locking mechanism is linked to automatically switch between the first use state and the second use state, so that the scooter can be quickly and conveniently switched between the first use state and the second use state.

[0051] Specifically, see Figures 5 to 16As shown, the locking mechanism includes a locking pin 10 that extends in the up and down direction and is slidably disposed on the rotating base 6 along its own length direction. A first locking groove 22a is provided on the mounting seat 22 for the upper part of the locking pin 10 to be inserted thereinto in a matching manner, and a second locking groove 31a is provided on the front wheel seat 31 for the lower part of the locking pin 10 to be inserted thereinto in a matching manner. When the locking mechanism is in the first locking state, the upper part of the locking pin 10 is inserted into the first locking groove 22a in a matching manner, and the lower part of the locking pin 10 is disengaged from the second locking groove 31a, so that the rotating base 6 and the mounting seat 22 are locked to each other, as Figure 11 and Figure 13 shown, so that the joystick 11 cannot rotate relative to the main frame 2; when the locking mechanism is in the second locking state, the lower part of the locking pin 10 is inserted into the second locking groove 31a in a matching manner, and the upper part of the locking pin 10 is disengaged from the first locking groove 22a, so that the rotating base 6 and the front wheel seat 31 are locked to each other, as Figure 14 and Figure 16 shown. At this time, the joystick 11 can rotate relative to the main frame 2 and drive the rotating base 6 to rotate synchronously around the second axis 102, so as to drive the front wheel assembly 3 to rotate synchronously to achieve steering.

[0052] The locking mechanism further includes an elastic member 10a for providing the force required for the locking pin 10 to move upward. Here, the elastic member 10a is specifically a spring sleeved on the locking pin 10. A sliding pressing block 8 that can move in the up and down direction is provided on the mounting seat 22. The locking pin 10 abuts upward against the sliding pressing block 8. The sliding pressing block 8 has a switchable first position and second position on the mounting seat 22, and the first position is above the second position. When the sliding pressing block 8 is in the first position, the upper part of the locking pin 10 is inserted into the first locking groove 22a under the action of the elastic member 10a, so that the locking mechanism is in the first locking state; when the sliding pressing block 8 is driven downward and switched to the second position, the locking pin 10 overcomes the acting force of the elastic member 10a, and its lower part is inserted into the second locking groove 31a, so that the locking mechanism is switched to the second locking state.

[0053] In this embodiment, a driving mechanism is provided on the scooter. During the process of the seat board 52 being converted from the retracted state to the opened state, the driving mechanism drives the sliding pressing block 8 to be converted from the first position to the second position, so as to drive the locking mechanism to be converted from the first locking state to the second locking state.

[0054] Specifically, refer to Figures 5 to 16As shown, the seat base 51 is fixedly arranged relative to the main frame 2. One end of the seat plate 52 is rotatably connected to the seat base 51 around the rotation axis 53 and is located behind the joystick 11. The above-mentioned driving mechanism includes a driving rod 7 extending in the up and down direction and capable of moving up and down relative to the seat base 51. The upper end of the driving rod 7 is connected to the seat plate 52, and the lower end of the driving rod 7 abuts against the sliding block 8. During the process of the seat plate 52 flipping downwards around the rotation axis 53, the driving rod 7 moves downwards from top to bottom, thereby driving the sliding block 8 to slide downwards and switch from the first position to the second position.

[0055] In this embodiment, as shown in the respective drawings, the seat base 51 has a hollow cavity 51c extending through in the up and down direction. The joystick 11 is rotatably inserted through the above-mentioned hollow cavity 51c around its own axis. A limiting structure for restricting the rotation angle of the joystick 11 around its own axis is also provided between the joystick 11 and the seat base 51. Here, as shown in Figure 6 As shown, a first limiting groove 11a and a second limiting groove 11b are provided on the joystick 11. Both the first limiting groove 11a and the second limiting groove 11b are waist-shaped grooves. Limiting pins (not shown in the figure) that are slidably matched with the first limiting groove 11a and the second limiting groove 11b are provided on the seat base 51 to achieve the limitation of the rotation angle of the joystick 11.

[0056] As shown in Figure 7 、 Figure 8 As shown, the seat base 51 includes a base rod 51a extending in the up and down direction and a base body 51b fixed to the upper part of the base rod 51a. The lower part of the base rod 51a is fixedly connected to the mounting seat 22. The seat plate 52 includes a plate body 52a and a transfer seat 52b fixed to one end of the plate body 52a. The transfer seat 52b has two groups respectively arranged on the left and right sides of the seat base 51. The base body 51b is rotatably connected to the two groups of transfer seats 52b around the rotation axis 53. The driving rod 7 has two groups respectively arranged on the left and right sides of the base body 51b. The upper ends of the two groups of driving rods 7 are respectively connected to the transfer seat 52b on their respective sides.

[0057] Here, gear slots 52d and arc-shaped guide slots 52c are provided on the two groups of transfer seats 52b of the seat plate 52. Among them, the gear slot 52d is an arc-shaped slot with the axis line of the rotation axis 53 as the rotation center line, mainly providing rotation guidance and gear locking for the seat plate 52 when the seat plate 52 is switched between the open state and the retracted state. A gear pin (not shown in the figure) that is slidably inserted into the gear slot 52d is provided on the base body 51b, and the axis line of the gear pin is parallel to the axis line of the rotation axis 53.

[0058] The arc-shaped guide groove 52c is used to cooperate with the driving rod 7 to drive the driving rod 7 to move up and down during the rotation of the seat plate 52. Specifically, the arc-shaped guide groove 52c has a first end 52c1 and a second end 52c2 respectively provided at two ends with different extending directions of itself. The distance between the arc-shaped guide groove 52c and the rotating shaft 53 is set to gradually increase from the first end 52c1 to the second end 52c2. The upper part of the driving rod 7 has a guide pin 7a slidably inserted into the arc-shaped guide groove 52c, and the axis line of the guide pin 7a is always located below the rotating shaft 53. When the seat plate 52 is in the retracted state, as Figure 12 shown, the guide pin 7a is located at the first end 52c1; when the seat plate 52 is in the opened state, as Figure 15 shown, the guide pin 7a is located at the second end 52c2. That is to say, during the process of the seat plate 52 being converted from the retracted state to the opened state, the distance between the guide pin 7a and the rotating shaft 53 gradually increases, and the driving rod 7 moves downward, thereby driving the sliding pressure block 8 to move downward from top to bottom, and further switching from the first position to the second position, so that the locking mechanism correspondingly switches from the first locking state to the second locking state. A shielding cover 52e is fixedly provided on the outer side of each adapter seat 52b.

[0059] Referring to the figures, in the scooter of this embodiment, a handle base 13 is fixedly provided at the bottom of the joystick 11. A plurality of linkage rods 9 are provided between the handle base 13 and the rotating base 6. All the linkage rods 9 are parallel to each other. One end of the linkage rod 9 is rotatably connected to the handle base 13 around the third axis 91, and the other end of the linkage rod 9 is rotatably connected to the rotating base 6 around the fourth axis 92. The axis lines of the above-mentioned third axis 91 and fourth axis 92 are both parallel to the axis line of the joystick 11. Thus, when driving the joystick 11 to rotate around its own axis line, the rotating base 6 can be correspondingly driven to rotate around the second axis 102 through the linkage rod 9. Here, the third axis 91 and the fourth axis 92 are integrally provided with the linkage rod 9 to form a U-shaped rod. There are two linkage rods 9, and the lengths of the two linkage rods 9 are the same. The two linkage rods 9 are respectively arranged on two different sides of the connection line of the projections of the axis line of the second axis 102 and the axis line of the joystick 11 on the same horizontal plane.

[0060] In the scooter, during specific setting, referring to Figure 10As shown, the rod body portion of the joystick 11 slidably passes through the hollow cavity 51c of the seat plate base 51 and downward through the mounting seat 22. The handle base 13 is located below the mounting seat 22. The sliding pressure block 8 is arranged on the mounting seat 22 to be capable of only moving up and down. The sliding pressure block 8 has an annular body 8a and a convex portion 8b protruding outwardly and extending from the outer peripheral portion of the annular body 8a. A guiding chute for providing up and down sliding guidance for the sliding pressure block 8 is arranged on the mounting seat 22, and the portion corresponding to provide the convex portion 8b in the guiding chute constitutes a first locking groove 22a. The upper portion of the locking pin 10 can be correspondingly inserted into the first locking groove 22a and abuts upward against the bottom of the convex portion 8b. The rotating base 6 is arranged on the front side of the joystick 11 and the handle base 13 and is connected to the handle base 13 through two linkage rods 9.

[0061] The working process of this embodiment will be specifically described below:

[0062] See Figures 11 to 13 As shown, the scooter is in the first use state and the seat plate 52 is in the retracted state. At this time, the locking mechanism is in the first locking state, so that the rotating base 6 and the mounting seat 22 are locked to each other, and the joystick 11 cannot rotate relative to the mounting seat 22. The user cannot drive the front wheel assembly 3 to turn by rotating the joystick 11. At this time, the scooter is used as a conventional scooter. The user can step on the pedal 21 and hold the handle rod 12, and control the direction of the scooter by tilting the body.

[0063] See Figures 14 to 16 As shown, when it is necessary to convert the scooter to the second use state, the seat plate 52 is turned downward and backward so that the seat plate 52 is converted to the open state for the user to sit and stand. During the above process, the driving rod 7 moves downward, driving the sliding pressure block 8 to move downward and convert from the first position to the second position, so that the locking pin 10 moves downward and is correspondingly inserted into the second locking groove 31a on the front wheel seat 31, so that the locking mechanism is converted to the second locking state, the front wheel seat 31 and the rotating base 6 are locked to each other, and the locking between the rotating base 6 and the front wheel seat 31 is released. At this time, the joystick 11 can rotate relative to the mounting seat 22 around its own axis, and during the rotation of the joystick 11, it can be linked to make the rotating base 6 rotate around the second axis 102, so that the front wheel assembly 3 rotates synchronously accordingly to realize the steering control of the front wheel assembly 3.

[0064] The above embodiments are only for illustrating the technical concept and features of the present invention, and the purpose is to enable those skilled in this technology to understand the content of the present invention and implement it. It cannot be used to limit the protection scope of the present invention. Any equivalent changes or modifications made according to the spirit of the present invention should be covered within the protection scope of the present invention.
