Description

Technical Field

[0001] This invention relates to the field of children's toy technology, and in particular to a children's scooter. Background Technology

[0002] Children's scooters are common sports toys during children's growth. As children grow older, their physical functions, sense of balance, and exercise needs will change significantly. Young children (e.g., 1-3 years old) usually have weaker balance and are more suitable to sit on the seat and push off the ground with their feet, or be pushed by their parents with the help of a push bar. As children get older (e.g., 3 years and older), their motor coordination ability increases and they are no longer satisfied with riding mode, but tend to stand on the pedals to glide.

[0003] However, existing children's vehicles are usually limited in function and mostly adopt a fixed design. For example, scooters are only for toddlers to sit on and cannot be converted into a standing gliding mode; while regular scooters are suitable for older children, they cannot meet the riding needs of younger children. This limited functionality makes it difficult for existing children's vehicles to adapt to children's growing needs, and they are often left idle, reducing the utilization rate of the products and increasing the abandonment rate. Summary of the Invention

[0004] The purpose of this invention is to provide a children's scooter that allows the support seat to flexibly switch between a seat state and a stem state by rotating the support seat and changing the grip installation position. This caters to the riding needs of children of different ages, as well as the needs of parents to assist in pushing and independent gliding, effectively adapting to children's growth and changes, increasing product utilization and reducing abandonment rate.

[0005] To achieve the above objectives, the present invention provides a children's scooter, comprising: A skateboard body having a footrest surface; A support base is provided, the front end of which is rotatably mounted on the slide plate. The side wall of the support base facing away from the slide plate has a seat cushion surface. The support base has a first mounting position near the hinge position with the slide plate and a second mounting position at the rear end. A first grip, which can be detachably mounted on the first mounting position or the second mounting position, is for a child to hold; A second grip, which can be detachably mounted on the second mounting position, is for parents to hold; The support base has a seated state and a riser state within its rotational range relative to the sliding plate, and the support base can switch between and lock between the seated state and the riser state. In the seated position, the support body extends tilted rearward toward the skateboard body, the seat cushion faces upward for a child to sit on, the first handle is installed at the first mounting position, and the second handle is installed at the second mounting position; In the upright position, the support body rotates in the direction away from the slide body to an upwardly extended position, the first mounting position is empty, and the first handle is installed in the second mounting position.

[0006] Furthermore, the children's scooter also includes a pivot assembly, through which the front end of the support seat is connected to the skateboard body; The pivot assembly includes a connecting seat, a pivot block, and an angle locking structure. The connecting seat is mounted on the sliding plate body. The pivot block is integrally formed with the support body. The pivot block is rotatably mounted on the connecting seat. A receiving groove is provided on the end face of the connecting seat facing the pivot block. The angle locking structure includes a first locking plate, a first elastic element, a second locking plate, and an unlocking end cap. The first locking plate is housed in the receiving groove and can reciprocate within the receiving groove along the pivotal axial direction. The two ends of the first elastic element are respectively disposed at the bottom of the receiving groove and the end face of the first locking plate near the receiving groove, so as to drive the first locking plate to slide away from the receiving groove. A locking block is provided on the end face of the first locking plate away from the receiving groove. A pivot hole is provided on the pivot block and extends along the pivotal axial direction. The second locking plate is disposed in the pivot hole and integrally formed with the pivot hole. The second locking plate is provided with at least two locking holes. The unlocking end cap is slidably disposed at the end of the pivot hole away from the connecting seat and abuts against the first locking plate. When the support body is switched to the seat state or the upright state, the locking block can be engaged into different locking holes under the action of the first elastic member to restrict the rotation of the pivot block relative to the connecting seat. When the unlocking end cap is pressed, the unlocking end cap pushes the first locking plate to slide into the receiving groove against the elastic force of the first elastic member, so that the locking block disengages from the locking hole, thereby releasing the rotation restriction on the pivot block.

[0007] Furthermore, the first locking plate is provided with two locking blocks, which are spaced apart along the rotation direction of the pivot block and are respectively referred to as the first locking block and the second locking block. The number of locking holes is three and is referred to as the first locking hole, the second locking hole and the third locking hole. The first locking hole, the second locking hole and the third locking hole are distributed sequentially at intervals along the rotation direction of the pivot block. When the support body is in the seat state, the first locking block is inserted into the first locking hole, and the second locking block is inserted into the second locking hole; When the support body is in the riser state, the first locking block is inserted into the second locking hole, and the second locking block is inserted into the third locking hole.

[0008] Furthermore, the unlocking end cap has a mounting plug on its end face facing the second locking plate, and the second locking plate has a mounting hole that matches the mounting plug. The mounting plug passes through the mounting hole to connect the unlocking end cap to the second locking plate. The unlocking end cap has a push rod on its end face facing the first locking plate, and the position of the push rod corresponds to the position of the locking block. When the unlocking end cap is pressed, the push rod extends into the locking hole and pushes against the locking block to push the locking block out of the locking hole.

[0009] Furthermore, the unlocking end cap is provided with a plurality of mounting plugs, which are evenly spaced along the pivot rotation direction. The end of each mounting plug is provided with a guide wedge, which has a guide slope and a right-angle stop surface. The mounting plug can be inserted into the mounting hole by means of its elastic deformation. When the mounting plug is inserted into the mounting hole and the guide wedge protrudes from the mounting hole, under the elastic force of the first elastic element, the right-angle stop surface abuts against the end face of the second locking plate facing the first locking plate.

[0010] Furthermore, the bottom of the receiving groove is provided with a guide rod, which extends along the axial direction of the pivot assembly. A guide hole is correspondingly provided on the first locking plate, and the guide rod passes through the guide hole. The first elastic element is sleeved on the outer periphery of the guide rod. The bottom of the receiving groove is provided with an installation groove around the root of the guide rod, and one end of the first elastic element is received and abuts against the installation groove. The guide rod, the guide hole, and the first elastic element are all multiple and are spaced apart along the pivot rotation direction. The guide hole and the locking block are staggered.

[0011] Furthermore, the pivot assembly includes two pivot blocks and two angle locking structures; Two pivot blocks are spaced apart along the pivot axis at the front end of the support body. The connecting seat is located between the two pivot blocks. The connecting seat has receiving grooves on its end faces facing the two pivot blocks. The two angle locking structures are respectively fitted into the two receiving grooves and the two pivot blocks.

[0012] Furthermore, the pivot assembly also includes a height adjustment assembly, through which the connecting seat is connected to the skateboard body, the height adjustment assembly being configured to adjust the relative distance between the connecting seat and the skateboard body.

[0013] Furthermore, the height adjustment assembly includes an adjustment riser, an adjustment sleeve, a positioning block, and a second elastic element; The adjusting riser is located at the bottom of the connecting seat and extends vertically. Multiple first positioning grooves are spaced axially on the outer wall of the adjusting riser. The adjusting sleeve is located at the front end of the sliding plate. The adjusting riser is slidably inserted into the adjusting sleeve. The positioning block is slidably mounted on the adjusting sleeve and can pass through the wall of the adjusting sleeve and engage in one of the first positioning grooves to lock the position of the adjusting riser relative to the adjusting sleeve. A second elastic element is located between the adjusting sleeve and the positioning block. The second elastic element applies an elastic force towards the adjusting riser to the positioning block, causing it to engage in the aligned first positioning groove, thereby locking the position of the adjusting riser relative to the adjusting sleeve.

[0014] Furthermore, the height adjustment assembly also includes a locking wrench. The outer wall of the adjusting riser is provided with a plurality of second positioning grooves spaced apart along its axial direction. The adjusting riser is provided with a first sliding groove opened along its axial direction. The first sliding groove is connected to the plurality of second positioning grooves. The locking wrench is rotatably mounted on the adjusting sleeve. The locking wrench is provided with a locking protrusion. The locking protrusion is accommodated in the first sliding groove or the second positioning groove. When the locking protrusion is located in the second positioning groove, the locking wrench presses the adjusting riser to lock the adjusting riser onto the adjusting sleeve. When the locking protrusion is located in the first sliding groove, the clamping force of the locking wrench on the adjusting riser is released, and the adjusting riser can slide axially relative to the adjusting sleeve.

[0015] Compared with the prior art, the beneficial effects of this invention's children's scooter are as follows: the front end of the support seat is rotatably mounted on the skateboard body, allowing the support seat to rotate around its hinge position with the skateboard body, thereby switching and locking between a seat state and a stem state. In the seat state, the support seat extends backward and provides a seat cushion for the child to sit on, with a first handlebar installed at the first mounting position for the child to hold and a second handlebar installed at the second mounting position for the parent to push, realizing the functions of child riding and parental assistance in pushing. In the stem state, the support seat rotates forward and extends upward to form a stem, and the second handlebar is reused at the second mounting position as the scooter's control handle, realizing the function of standing and gliding. By reusing the support seat at different angles and the detachable cooperation of the first and second handlebars at the first and second mounting positions, the same children's scooter can meet the riding and gliding needs of children at different stages of growth, effectively solving the problems of single function and high idle rate of existing children's sports vehicles, and reducing product abandonment rate.

[0021] The technical solution of the present invention will be further described below with reference to the embodiments and accompanying drawings.

[0022] like Figure 1 , 2 As shown, an embodiment of the present invention provides a children's scooter, comprising: Skateboard body 1, with a foot surface 11 on the skateboard body 1; The support body 2 has its front end rotatably mounted on the slide body 1. The side wall of the support body 2 facing away from the slide body 1 has a seat pad surface 21. The support body 2 has a first mounting position 22 near the hinge position with the slide body 1, and a second mounting position 23 is provided at the rear end of the support body 2. The first grip 3 can be detachably mounted on the first mounting position 22 or the second mounting position 23 for children to hold; The second grip 4 can be detachably installed on the second mounting position 23 for parents to hold; The support base 2 has a seat state and a riser state within its rotational range relative to the slide body 1, and the support base 2 can switch between and lock between the seat state and the riser state. In the seated position, the support seat 2 extends backward toward the skateboard body 1, with the seat cushion 21 facing upward for the child to sit on. The first handle 3 is installed in the first mounting position 22, and the second handle 4 is installed in the second mounting position 23. In the upright position, the support body 2 rotates in the direction away from the slide body 1 to the upward extension position, the first mounting position 22 is empty, and the first grip 3 is installed in the second mounting position 23.

[0023] Based on the above technical solution, the front end of the support seat 2 is rotatably mounted on the skateboard body 1, allowing the support seat 2 to rotate around its hinge position with the skateboard body 1. This enables switching and locking between the seat state and the upright state. In the seat state, the support seat 2 tilts backward and extends to provide a seat cushion 21 for the child to sit on. This, combined with the first handlebar 3 installed at the first mounting position 22 for the child to hold and the second handlebar 4 installed at the second mounting position 23 for the parent to push, realizes the functions of child riding and parent-assisted pushing. In the upright state, the support seat 2 rotates forward and extends upward to form an upright. The second handlebar 4 is reused at the second mounting position 23 as the control handle of the scooter, realizing the standing gliding function. By reusing the support seat 2 at different angles and the detachable cooperation of the first handlebar 3 and the second handlebar 4 at the first mounting position 22 and the second mounting position 23, the same children's scooter can meet the riding and gliding needs of children at different stages of growth, effectively solving the problems of single function and high idle rate of existing children's sports vehicles and reducing product abandonment rate.

[0024] In one specific embodiment, such as Figure 12 , 13As shown in Figure 14, a first mounting cylinder is provided at the first mounting position 22 of the support body 2. The extension direction of the first mounting cylinder forms an angle with the horizontal direction. The first mounting cylinder has a first mounting cavity and an adjustment hole. The first handle 3 includes a first rod 31 and a first gripping part 311 disposed at the upper end of the first rod 31. The first rod 31 can be slidably inserted into the first mounting cavity. The first rod 31 has a first receiving cavity 312 inside. A fixed bracket 32 ​​is fixedly housed in the first receiving cavity. A first waist-shaped hole 321 is opened on the fixed bracket 32. The length extension direction of the first waist-shaped hole 321 forms an angle with the axial direction of the first rod 31. A through hole 313 communicating with the first receiving cavity 312 is opened in the radial direction of the first rod 31. A button 33 that slides radially is provided at the through hole 313. A first transmission wedge 331 is provided on the end of the button 33 located in the first receiving cavity 312. A transmission member 34 extending along the axial direction of the first mounting cylinder is placed inside the first receiving cavity 312. A second transmission wedge 341 is provided at one end of the transmission member 34 near the button 33. The inclined surfaces of the first transmission wedge 331 and the second transmission wedge 341 abut against each other. A first adjusting rod 35 is also accommodated in the first receiving cavity 312. The first adjusting rod 35 can slide along the axial direction of the first rod body 31. A third elastic member 37 is provided between the first adjusting rod 35 and the transmission member 34. The two ends of the third elastic member 37 are respectively connected to one end of the first adjusting rod 35 and the end of the transmission member 34 away from the button 33. An adjusting rod 35 has a second receiving groove 351 extending radially along the first adjusting rod 35. A second oblong hole 352 is provided on the side wall of the second receiving groove. The length direction of the second oblong hole 352 is perpendicular to the axial direction of the first rod body 31. An adjusting plug 36 is slidably received in the second receiving groove 351. A transmission column 361 is provided on the adjusting plug 36. The transmission column 361 passes through the second oblong hole 352 and the first oblong hole 321 in sequence. The adjusting plug 36 can be inserted into the adjusting hole.

[0025] The first rod 31 of the first grip 3 is a movable part, inserted into the first mounting cavity of the first mounting cylinder on the support base 2. The first mounting cylinder plays a guiding and supporting role, and its multiple axially distributed adjustment holes define different height levels.

[0026] When the user presses button 33, the first transmission wedge 331 presses against the second transmission wedge 341, driving the transmission component 34 to move axially along the first mounting cylinder. The transmission component 34 pushes the first adjusting rod 35 to move axially through the third elastic element 37. The first adjusting rod 35 drives the adjusting plug 36 to move axially, causing the transmission column 361 on the adjusting plug 36 to slide in the first oblong hole 321 of the fixed bracket 32. Since the first oblong hole 321 has an included angle, and the second oblong hole 352 on the first adjusting rod 35 restricts the axial displacement freedom of the transmission column 361, the axial thrust is converted into radial thrust through the cooperation of the transmission column 361 and the first oblong hole 321, driving the adjusting plug 36 to retract into the second receiving groove 351, thereby disengaging from the adjusting hole and unlocking.

[0027] Furthermore, in another specific embodiment, such as Figure 12 , 15 As shown in Figures 16, 17, and 18, a second mounting cylinder 231 is provided at the second mounting position 23 of the support body 2. The second mounting cylinder 231 extends in the front-rear direction and has a second mounting cavity 2311. A locking groove 2312 is provided on the second mounting cylinder 231, which extends circumferentially along the second mounting cylinder 231 and communicates with the second mounting cavity 2311. The second handle 4 includes a second rod 41, a third rod 42, and a second gripping part 43. The second rod 41 can be slidably inserted into the second mounting cavity 2311. The two ends of the third rod 42 are respectively connected to the rear end of the second rod 41 and the second gripping part 43. A second sliding groove 411 extending axially is provided on the second rod 41, and a second locking groove 412 is also provided on the second rod 41. 412 extends circumferentially along the second rod 41. The second slot 412 is connected to the second slide groove 411. The second mounting cylinder 231 is provided with a locking block 2313. The locking block 2313 is slidably disposed on the locking groove 2312. The end of the locking block 2313 passes through the locking groove 2312 and can be slidably accommodated in the second slot 412 and the second slide groove 411. The bottom center of the second slot 412 is provided with a second displacement protrusion 4121. The first rod 31 is provided with a third slide groove 314 extending axially. The first rod 31 is provided with a plurality of first slots 315 spaced apart axially. The first slots 315 extend circumferentially along the first rod 31. The first slots 315 are connected to the third slide groove 314. The bottom center of the first slots 315 is provided with a first displacement protrusion 3151.

[0028] When the user needs to install the second grip 4, the front end of the second rod 41 is aligned with the second mounting cavity 2311 of the second mounting cylinder 231 on the support base 2. The angle of the second rod 41 needs to be adjusted so that the end of the locking block 2313 on the second mounting cylinder 231 enters the second sliding groove 411 on the second rod 41. Since the second sliding groove 411 extends axially, the second rod 41 can slide axially without obstruction within the second mounting cavity 2311. When the second rod 41 slides to the preset axial position, that is, when the second slot 412 and the locking block 2313 are aligned in the circumferential direction, the user moves along the second mounting cylinder 231... When the locking block 2313 is circumferentially moved, it moves along the locking groove 2312, and its end enters the second slot 412 from the second sliding groove 411 in the axial direction. Since the second slot 412 extends circumferentially, its sidewall blocks the axial displacement path of the locking block 2313, thereby locking the second rod 41 in the axial direction. During the process of the locking block 2313 entering the second slot 412, its end will pass over the second repositioning protrusion 4121 set in the middle of the bottom of the groove. After the locking block 2313 passes over the second repositioning protrusion 4121, the second repositioning protrusion 4121 can prevent it from sliding in the opposite direction. Similarly, when the first lever 31 is adjusted by the third slide groove 314 and the first slot 315, the first shifting protrusion 3151 in the first slot 315 also plays the same limiting role, ensuring that the locking block 2313 will not slide back to the slide groove position due to vibration and thus unlock under severe use.

[0029] In one specific embodiment, such as Figure 19 , 20 As shown, a steering seat 12 is fixedly provided at the front end of the skateboard body 1. A steering cross bridge 14 is pivotally connected to the steering seat 12 via a steering kingpin 121. Front wheels 15 are respectively installed at both ends of the steering cross bridge 14. The steering cross bridge 14 is configured to swing around the steering kingpin 121. A steering follower groove 141 integrally formed with the steering cross bridge 14 is provided at the middle of the steering cross bridge 14. The end of the steering seat 12 extends into and is accommodated in the steering follower groove 141. A reset elastic member 13 is sleeved on the steering kingpin 121. The two ends of the reset elastic member 13 are respectively connected to the left and right sides of the steering cross bridge 14.

[0030] Specifically, the reset elastic element 13 adopts a torsion spring structure.

[0031] When gliding (with the support seat 2 in the upright position) or riding (with the support seat 2 in the seat position), the child applies a lateral deflection force to the support seat 2 by holding the handlebars and shifting their body weight. This deflection force is transmitted to the steering seat 12. When the steering seat 12 deflects radially with the support seat 2, its end extending into the steering follower groove 141 slides and abuts against the side wall of the steering follower groove 141. Since the steering follower groove 141 and the steering crossbeam 14 are an integrated structure, the displacement of the end of the steering seat 12 forces the steering crossbeam 14 to swing angularly around the steering kingpin 121. As the steering crossbeam 14 swings around the steering kingpin 121... The front wheels 15 mounted at both ends of the scooter deflect at an angle relative to the centerline of the scooter body 1. During this process, the axial direction of the two front wheels 15 changes, thereby realizing the steering action of the scooter. During the swinging process of the steering cross bridge 14 relative to the steering seat 12, the reset elastic element 13 sleeved on the steering kingpin 121 is twisted or compressed. Since its two ends are connected to the steering cross bridge 14 and the steering seat 12 respectively, it will generate elastic deformation and store elastic potential energy with the relative displacement of the two. When the lateral deflection force is removed, the reset elastic element 13 releases the potential energy, drives the steering cross bridge 14 to swing in the opposite direction and return to the neutral position, so that the vehicle returns to the straight driving state.

[0032] Specifically, both the first elastic element 532 and the third elastic element 37 are spring structures.

[0033] In one specific embodiment, the seat cushion surface 21 is made of thermoplastic elastomer material (TPE).

[0034] The seat cushion 21 is made of TPE elastic material. By utilizing the material's own physical resilience, it can effectively absorb and cushion the vibration generated when the scooter is riding on uneven roads, thus improving riding comfort.

[0035] During scooter riding, children are prone to collisions due to the uncertainty of their motion. By placing the elastic seat cushion 21 on the outside of the support seat 2, the local pressure generated at the moment of collision can be reduced, increasing the safety of children playing. When the scooter accidentally hits a protrusion, the elastic deformation of the seat cushion 21 can absorb most of the instantaneous impact, thereby protecting the support seat 2, effectively preventing stress cracking or plastic deformation of the structural frame, maintaining the structural integrity of the support seat 2, and reducing the failure rate of the entire vehicle.

[0036] Preferably, such as Figure 3 , 4 As shown in Figures 5, 6, and 7, the children's scooter also includes a pivot assembly 5, and the front end of the support seat 2 is connected to the skateboard body 1 through the pivot assembly 5; The pivot assembly 5 includes a connecting seat 51, a pivot block 52 and an angle locking structure 53. The connecting seat 51 is mounted on the sliding plate body 1. The pivot block 52 is integrally formed with the support body 2. The pivot block 52 is rotatably mounted on the connecting seat 51. A receiving groove 511 is provided on the end face of the connecting seat 51 facing the pivot block 52. The angle locking structure 53 includes a first locking plate 531, a first elastic element 532, a second locking plate 533, and an unlocking end cap 534. The first locking plate 531 is accommodated in a receiving groove 511 and can reciprocate within the receiving groove 511 along the pivotal axial direction. The two ends of the first elastic element 532 are respectively disposed on the bottom of the receiving groove 511 and the end face of the first locking plate 531 near the receiving groove 511, so as to drive the first locking plate 531 away from the receiving groove. The first locking plate 531 is provided with a locking block 5312 on the end face of the first locking plate 531 away from the receiving groove 511. The pivot block 52 is provided with a pivot hole, which extends along the pivot axis. The second locking plate 533 is provided in the pivot hole and is integrally formed with the pivot hole. The second locking plate 533 is provided with at least two locking holes 5331. The unlocking end cover 534 is slidably provided at one end of the pivot hole away from the connecting seat 51. The unlocking end cover 534 abuts against the first locking plate 531. When the support body 2 is switched to the seat state or the riser state, the locking block 5312 can be locked into different locking holes 5331 respectively under the action of the first elastic member 532, so as to restrict the rotation of the pivot block 52 relative to the connecting seat 51. When the unlocking end cover 534 is pressed, the unlocking end cover 534 pushes the first locking plate 531 to slide into the receiving groove 511 against the elastic force of the first elastic member 532, so that the locking block 5312 disengages from the locking hole 5331, thereby releasing the rotation restriction on the pivot block 52.

[0037] In the initial locked state, the first elastic element 532 is under pressure, and the elastic pressure it generates acts on the first locking plate 531, causing the first locking plate 531 to slide outward along the axial direction (away from the bottom of the groove) in the receiving groove 511 of the connecting seat 51. The locking block 5312 on the first locking plate 531 extends out and is engaged in the corresponding locking hole 5331 on the second locking plate 533 in the pivot block 52. Due to the engagement of the locking block 5312 and the locking hole 5331, the rotational freedom of the pivot block 52 relative to the connecting seat 51 is physically restricted, so that the support body 2 is stably locked in the seat state or the upright state. When the user needs to switch the support body 2 to seat mode or stand-up mode, press the unlock end cover 534 located on the outside. Since the unlock end cover 534 abuts against the first locking plate 531, the pressing force overcomes the elastic force of the first elastic element 532, pushing the first locking plate 531 to the axial inward side, that is, towards the bottom of the receiving groove 511, and slides. As the displacement occurs, the locking block 5312 completely disengages from the locking hole 5331 of the second locking plate 533. After the locking block 5312 disengages from the locking hole 5331, the rotation restriction of the pivot block 52 is released, and the user can rotate the support body 2 around the pivot axis. The support body 2 is in a temporarily unlocked rotational state. When the support body 2 rotates to another preset angle, such as from the seat state to the upright state, the locking block 5312 on the first locking plate 531 aligns with another locking hole 5331 as it rotates. The first elastic element 532, which has lost its physical constraint, releases its elastic potential energy, driving the first locking plate 531 to pop out axially again. The locking block 5312 automatically engages in the locking hole 5331, completing the automatic secondary locking after the state switch.

[0038] By setting the unlocking end cap 534 and using its axial displacement to control the locking, a simple interaction point is provided for the user. The user does not need complicated tools or cumbersome disassembly actions. The user can switch between the stand tube state and the seat state by simply pressing and rotating, which reduces the operation threshold and meets the user experience of children. The pivot block 52 is integrally formed with the support body 2, and the second locking plate 533 is integrally formed with the pivot block 52, which reduces the stacking of scattered parts, reduces the cumulative tolerance, and can effectively bear the torque and impact force from different directions, so that the scooter can maintain good structural rigidity in both states.

[0039] The first locking plate 531, the second locking plate 533, the first elastic element 532, and the locking block 5312 are all housed in a relatively enclosed space formed by the connecting seat 51, the pivot block 52, and the unlocking end cover 534. This effectively prevents external sand and dust and debris from entering, reduces mechanical wear and jamming risks, and ensures the accuracy and smoothness of the pivot locking mechanism during long-term use.

[0040] More preferably, such as Figure 5 , 6 As shown, the first locking plate 531 is provided with two locking blocks 5312. The two locking blocks 5312 are spaced apart along the rotation direction of the pivot block 52 and are respectively referred to as the first locking block 53121 and the second locking block 53122. The number of locking holes 5331 is three and are referred to as the first locking hole 53311, the second locking hole 53312 and the third locking hole 53313. The first locking hole 53311, the second locking hole 53312 and the third locking hole 53313 are distributed sequentially at intervals along the rotation direction of the pivot block 52. When the support body 2 is in the seat state, the first locking block 53121 is inserted into the first locking hole 53311, and the second locking block 53122 is inserted into the second locking hole 53312. When the support body 2 is in the riser state, the first locking block 53121 is inserted into the second locking hole 53312, and the second locking block 53122 is inserted into the third locking hole 53313.

[0041] A first locking block 53121 and a second locking block 53122 are provided on the first locking plate 531, spaced apart along the rotation direction of the pivot block 52. This allows two independent locking blocks 5312 to simultaneously engage with the corresponding two locking holes 5331 (first locking hole 53311 and second locking hole 53312, or second locking hole 53312 and third locking hole 53313) in both the seat and stand-up pole positions. Compared to a single-point locking structure, this reduces the pressure per unit contact area and prevents... Under intense motion scenarios, the locking block 5312 undergoes plastic deformation or fracture due to stress concentration, enhancing the structural stability of the support body 2 under different working conditions. The reuse of the second locking hole 53312 in the two locking states can be achieved by simply opening three locking holes 5331 on the pivot block 52. Under the premise of the rotation angle requirement of the support body 2, the opening density on the pivot block 52 and the second locking plate 533 is reduced, retaining more solid material, thereby maintaining the overall rigidity of the pivot block 52 itself.

[0042] More preferably, such as Figure 7 As shown, the unlocking end cover 534 has a mounting plug 5341 on its end face facing the second locking plate 533. The second locking plate 533 has a mounting hole 5332 that matches the mounting plug 5341. The mounting plug 5341 passes through the mounting hole 5332 to connect the unlocking end cover 534 to the second locking plate 533. The unlocking end cover 534 has a push rod 5342 on its end face facing the first locking plate 531. The position of the push rod 5342 corresponds to the position of the locking block 5312. When the unlocking end cover 534 is pressed, the push rod 5342 extends into the locking hole 5331 and pushes the locking block 5312 to push the locking block 5312 out of the locking hole 5331.

[0043] In one specific embodiment, the unlocking end cover 534 is provided with three push rods 5342 spaced apart. When the support body 2 is in the seat state or the upright state, two of the push rods 5342 abut against the two locking blocks 5312 one by one.

[0044] More preferably, such as Figure 7As shown, the unlocking end cover 534 is provided with multiple mounting plugs 5341. The multiple mounting plugs 5341 are evenly spaced along the pivot rotation direction. The end of the mounting plug 5341 is provided with a guide wedge 53411. The guide wedge 53411 has a guide slope 534111 and a right angle stop surface 534112. The mounting plug 5341 can be inserted into the mounting hole 5332 by its elastic deformation. When the mounting plug 5341 is inserted into the mounting hole 5332 and the guide wedge 53411 protrudes from the mounting hole 5332, under the elastic force of the first elastic member 532, the right-angle stop surface 534112 abuts against the end face of the second locking plate 533 facing the first locking plate 531.

[0045] When assembling the unlocking end cap 534, by pressing inward, multiple mounting plugs 5341 are aligned with the mounting holes 5332 on the second locking plate 533. The guide wedge 534111 of the guide wedge 53411 is pressed against the edge of the mounting hole 5332, triggering the mounting plugs 5341 to produce radial elastic deformation. When the guide wedge 53411 completely passes through the mounting hole 5332, the mounting plugs 5341 elastically reset, causing the right-angle stop surface 534112 to pass over the inner wall edge of the second locking plate 533. Under the elastic force of the first elastic member 532, the right-angle stop surface 534112 abuts against the inner wall of the second locking plate 533.

[0046] When the mechanism is in the normal locked position, the first elastic element 532 always pushes the first locking plate 531 and the locking block 5312 outward. Since the locking block 5312 is inserted into the locking hole 5331, its end face is in close contact with the two corresponding push rods 5342 inside the unlocking end cover 534. The axial thrust generated by the first elastic element 532 is transmitted to the push rods 5342 through the locking block 5312. This thrust drives the unlocking end cover 534 to tend to disengage outward, thereby making the right-angle stop surface 534112 at the end of the mounting plug 5341 tightly pressed against the end face of the second locking plate 533 facing the first locking plate 531.

[0047] When the user presses the unlock end cap 534, regardless of which two locking holes 5331 are filled with locking blocks 5312, two of the three push rods 5342 will always be able to accurately correspond to and abut the locking blocks 5312. The push rods 5342 can push the locking blocks 5312 out of the locking holes 5331 to achieve unlocking.

[0048] More preferably, such as Figure 4As shown, the bottom of the receiving groove 511 is provided with a guide rod 512, which extends along the axial direction of the pivot assembly 5. The first locking plate 531 is provided with a corresponding guide hole 5311, and the guide rod 512 passes through the guide hole 5311. The first elastic member 532 is sleeved on the outer periphery of the guide rod 512. The bottom of the receiving groove 511 is provided with an installation groove 5111 around the root of the guide rod 512. One end of the first elastic member 532 is received and abuts against the installation groove 5111. There are multiple guide rods 512, guide holes 5311 and first elastic members 532, which are spaced apart along the pivot rotation direction. The guide holes 5311 and the locking blocks 5312 are staggered.

[0049] The installation process of the pivot assembly 5 is as follows: In the first receiving groove 511 of the connecting seat 51, multiple first elastic elements 532 are sleeved on the corresponding guide rods 512, and their ends are inserted into the mounting grooves 5111 at the bottom of the groove. The guide rods 512 provide axial guidance for the spring. The guide hole 5311 of the first locking plate 531 is aligned with the guide rod 512. Since the guide rod 512 is relatively long, it has entered the guide hole 5311 and completed the pre-positioning before the first locking plate 531 contacts the spring. Then, the first locking plate 531 is pushed in axially to compress the first elastic elements 532. The pivot block 52, which is integrally formed with the support body 2, is sleeved on the outer periphery of the connecting seat 51. At this time, the pivot hole of the second locking plate 533 is coaxially aligned with the first receiving groove 511. Under the action of elastic force, the locking block 5312 will automatically find and lock into the locking hole 5331 on the second locking plate 533 inside the pivot block 52. The pivot shaft passes through the pivot shaft of the second locking plate 533, the first locking plate 531, and the connecting seat 51 in sequence. Finally, the mounting plug 5341 of the unlocking end cover 534 is aligned with the mounting hole 5332 on the second locking plate 533, while ensuring that the push rod 5342 inside it extends into the corresponding locking hole 5331. The unlocking end cover 534 is pressed inward, and the guide wedge 53411 at the end of the mounting plug 5341 undergoes elastic deformation and passes through the mounting hole 5332. Then, under the action of the reverse pre-tightening force of the first elastic element 532, the right angle stop surface 534112 is tightly fastened to the inner side of the second locking plate 533. Thus, the entire pivot assembly 5 is assembled.

[0050] More preferably, such as Figure 3 As shown, the pivot assembly 5 includes two pivot blocks 52 and two angle locking structures 53; Two pivot blocks 52 are spaced apart along the axial direction of the pivot and are located at the front end of the support body 2. The connecting seat 51 is located between the two pivot blocks 52. The end face of the connecting seat 51 facing the two pivot blocks 52 is provided with receiving grooves 511 respectively. Two angle locking structures 53 are respectively assembled at the two receiving grooves 511 and the two pivot blocks 52.

[0051] The connecting seat 51 is positioned between two pivot blocks 52 and is used in conjunction with the angle locking structure 53 arranged symmetrically on both sides. This allows the axial load and radial torque transmitted from the support body 2 to the pivot assembly 5 to be evenly distributed on both sides, overcoming the overturning moment commonly found in single-sided locking structures. This ensures that the motion feedback of the internal motion components remains smooth and consistent during frequent state switching.

[0052] More preferably, such as Figure 8 As shown, the pivot assembly 5 also includes a height adjustment assembly 6. The connecting seat 51 is connected to the skateboard body 1 through the height adjustment assembly 6. The height adjustment assembly 6 is configured to adjust the relative distance between the connecting seat 51 and the skateboard body 1.

[0053] More preferably, such as Figure 4 , 8 As shown in Figures 1 and 10, the height adjustment assembly 6 includes an adjustment riser 61, an adjustment sleeve 62, a positioning block 63, and a second elastic element 64. An adjusting riser 61 is located at the bottom of the connecting seat 51 and extends vertically. Multiple first positioning grooves 611 are spaced axially on the outer wall of the adjusting riser 61. An adjusting sleeve 62 is located at the front end of the sliding plate 1. The adjusting riser 61 is slidably inserted into the adjusting sleeve 62. A positioning block 63 is slidably mounted on the adjusting sleeve 62. The positioning block 63 can pass through the wall of the adjusting sleeve 62 and engage with one of the first positioning grooves 611 to lock the position of the adjusting riser 61 relative to the adjusting sleeve 62. A second elastic element 64 is located between the adjusting sleeve 62 and the positioning block 63. The second elastic element 64 applies an elastic force towards the adjusting riser 61 to the positioning block 63, causing the positioning block 63 to engage with the aligned first positioning groove 611, thereby locking the position of the adjusting riser 61 relative to the adjusting sleeve 62.

[0054] In one specific embodiment, the second elastic element 64 adopts a spring structure.

[0055] When the user needs to adjust the height of the connecting seat 51, an external force is applied to overcome the elastic force of the second elastic element 64, driving the positioning block 63 to slide radially outward. The end of the positioning block 63 disengages from a first positioning groove 611 on the adjusting riser 61. At this time, the axial constraint of the adjusting riser 61 is released. In the unlocked state, the user pulls the connecting seat 51 upward or presses it downward axially. At this time, the adjusting riser 61 generates axial displacement under the guidance of the inner cavity of the adjusting sleeve 62. When the adjusting riser 61 moves to the target height, and the corresponding... When a certain first positioning groove 611 moves to a position coaxially aligned with the positioning insert 63, the second elastic element 64 releases the pre-tightened elastic force. This elastic force drives the positioning insert 63 to slide radially inward, pass through the tube wall of the adjusting sleeve 62, and accurately engage in the first positioning groove 611. Since the positioning insert 63 is simultaneously constrained by the circumferential constraint of the tube wall of the adjusting sleeve 62 and blocked axially by the first positioning groove 611, the axial degree of freedom of the adjusting riser 61 relative to the adjusting sleeve 62 is restricted, thereby completing the locking of the distance between the connecting seat 51 and the sliding plate 1.

[0056] More preferably, such as Figure 11 As shown, the height adjustment assembly 6 also includes a locking wrench 65. Multiple second positioning grooves 612 are spaced apart along the axial direction on the outer wall of the adjusting riser 61. A first sliding groove 613 is opened along the axial direction on the adjusting riser 61. The first sliding groove 613 is connected to the multiple second positioning grooves 612. The locking wrench 65 is rotatably mounted on the adjusting sleeve 62. The locking wrench 65 is provided with a locking protrusion 651, which is accommodated in the first sliding groove 613 or the second positioning groove 612. When the locking protrusion 651 is located in the second positioning groove 612, the locking wrench 65 presses the adjusting riser 61 to lock the adjusting riser 61 onto the adjusting sleeve 62. When the locking protrusion 651 is located in the first slide groove 613, the clamping force of the locking wrench 65 on the adjusting riser 61 is released, and the adjusting riser 61 can slide axially relative to the adjusting sleeve 62.

[0057] When the user needs to adjust the height, the locking wrench 65 set on the adjusting sleeve 62 is rotated. The rotation of the locking wrench 65 causes the locking protrusion 651, which was originally located in a second positioning groove 612, to slide. The locking protrusion 651 disengages from the second positioning groove 612 and enters the first sliding groove 613 connected to it. The axial limiting and radial clamping force of the locking wrench 65 on the adjusting riser 61 is released. After releasing the clamping, the user moves the adjusting riser 61 axially. The locking protrusion 651 slides axially within the first groove 613. When the adjusting riser 61 slides to the target height, aligning the user-selected second positioning groove 612 with the locking protrusion 651 in the axial position, the user rotates the locking wrench 65 again. The locking protrusion 651 moves from the axially extending first groove 613 into the corresponding second positioning groove 612, locking the axial degree of freedom of the adjusting riser 61. The user continues to tighten the locking wrench 65. The locking wrench 65 converts the rotational torque into radial pressure on the adjusting riser 61 through its mechanical configuration (such as an eccentric structure). The locking protrusion 651 is fastened in the corresponding second positioning groove 612, forming a tight interference fit between the adjusting riser 61 and the adjusting sleeve 62, locking the relative distance between them.

[0058] The physical nesting of the locking protrusion 651 and the second positioning groove 612 forms the first layer of locking (preventing axial movement), and the locking wrench 65 presses against the tube wall to form the second layer of fastening (eliminating the fit gap). This composite locking mechanism avoids the risk of instantaneous slippage of the adjustment mechanism due to insufficient friction under severe sliding or bumpy road conditions, ensuring the safety of children.

[0059] In summary, this invention provides a children's scooter with a support seat 2 rotatably mounted on the skateboard body 1 at its front end. This allows the support seat 2 to rotate around its hinged position with the skateboard body 1, enabling switching and locking between a seat state and a stem state. In the seat state, the support seat 2 extends backward and provides a seat cushion 21 for the child to sit on. This, combined with a first handlebar 3 mounted at the first mounting position 22 for the child to grip and a second handlebar 4 mounted at the second mounting position 23 for the parent to push, achieves both child riding and parent-assisted pushing functions. In the stem state, the support seat 2 rotates forward and extends upward to form a stem. The second handlebar 4 is reused at the second mounting position 23 as the scooter's control handle, enabling standing and gliding. By reusing the support seat 2 at different angles and allowing the first handlebar 3 and second handlebar 4 to detachably engage at the first mounting position 22 and the second mounting position 23, the same children's scooter can meet the riding and gliding needs of children at different stages of development. This effectively solves the problems of limited functionality and high idle rates in existing children's sports vehicles, reducing product abandonment rates.

[0060] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present invention, and these improvements and substitutions should also be considered within the scope of protection of the present invention.
