[0029] The present invention provides a toy vehicle in which, when a user is riding the vehicle, the tire of a first wheel rotates relative to the hub about a first axis when the user is not leaning, allowing the vehicle to move forward and backward. When the user leans left or right, the shift in the center of gravity of the user's body generates a lateral force on the first wheel. Under the action of this lateral force, the hub of the first wheel rotates about a second axis, causing the first wheel to deflect left or right, thereby changing the direction of movement of the first wheel and achieving the toy vehicle's steering function. The structural design of the toy vehicle allows the first wheel to swing a certain angle about the second axis simply by leaning the user, thereby changing the direction of movement of the first wheel. In other words, the direction of movement of the toy vehicle can be directly controlled by the first wheel, eliminating the need for additional steering control components. The structural design is simple, reducing the manufacturing cost of the toy vehicle. Because the second axis is tilted toward the second end of the frame, the intersection of the second axis and the ground falls forward of the contact point of the first wheel tire with the ground. Rotation of the first wheel tire about the first axis generates a aligning torque on the first wheel, preventing the first wheel from rotating too rapidly about the second axis and improving the steering stability of the toy vehicle.

[0053] Example 1

[0054] like Figures 1 to 7 As shown, this embodiment provides a toy car with a simple structure and capable of realizing the steering function of the toy car. The toy car includes a frame 1, a connecting frame 2 and a first wheel 3.

[0055] Among them, see Figure 1 、 Figure 2 and Figure 3 The vehicle frame 1 has a first end and a second end that are oppositely disposed. The connecting frame 2 is disposed on the first end of the vehicle frame 1. The first wheel 3 includes a hub 31 and a tire 32 coaxially disposed outside the hub 31. The tire 32 is capable of rotating relative to the hub 31 about a first axis. The hub 31 is disposed on the connecting frame 2 and is capable of rotating relative to the connecting frame 2 about a second axis. The second axis intersects the first axis and is inclined toward the second end of the vehicle frame 1. Rotation of the hub 31 about the second axis adjusts the direction of movement of the toy vehicle.

[0056] The above-mentioned toy car can be a pedal-assisted scooter, an electric scooter, a balance car, etc.

[0057] In the toy car provided in this embodiment, when the user is riding the toy car, when the user's body is not leaning, the tire 32 of the first wheel 3 rotates relative to the hub 31 about a first axis, allowing the toy car to move forward and backward. When the user's body leans left or right, the shift in the body's center of gravity generates a lateral force on the first wheel 3. Under the action of this lateral force, the hub 31 of the first wheel 3 rotates about a second axis, causing the first wheel 3 to deflect left or right, thereby changing the direction of movement of the first wheel 3 and achieving the toy car's steering function. The structural design of this toy car allows the first wheel 3 to swing a certain angle about the second axis simply by the user leaning sideways, thereby changing the direction of movement of the first wheel 3. In other words, the direction of movement of the toy car can be directly controlled by the first wheel 3, without the need for additional steering control components. This simplifies the structural design and reduces the manufacturing cost of the toy car.

[0058] Since the second axis is inclined toward the second end of the frame 1, the intersection of the second axis and the ground can fall in front of the contact point between the tire 32 of the first wheel 3 and the ground. During the rotation of the tire 32 of the first wheel 3 around the first axis, a self-aligning torque is generated on the first wheel 3, preventing the first wheel 3 from rotating too quickly around the second axis, thereby improving the steering stability of the toy car.

[0059] Reference Figure 2 In the orientation, the right end of the frame 1 is the first end, the left end of the frame 1 is the second end, the direction of the first axis is the direction perpendicular to the paper surface, and the direction of the second axis is the direction inclined toward the left end of the frame 1 relative to the first axis.

[0060] Optionally, a plurality of rolling elements are provided circumferentially between the tire 32 of the first wheel 3 and the hub 31. The tire 32 rolls with the hub 31 via the plurality of rolling elements, thereby reducing the resistance to rotation of the tire 32 relative to the hub 31 and improving the rotation efficiency of the tire 32. For example, the rolling elements may be balls or rollers.

[0061] See Figure 1 and Figure 3 The connecting frame 2 includes a first connecting shaft 21 and a second connecting shaft 22 arranged crosswise. Both ends of the first connecting shaft 21 are connected to the vehicle frame 1. The wheel hub 31 is coaxial and spaced apart outside the first connecting shaft 21. The second connecting shaft 22 can rotate relative to the first connecting shaft 21 around a second axis, and both ends of the second connecting shaft 22 are fixedly connected or rotationally connected to the inner ring of the wheel hub 31. The axis of the first connecting shaft 21 is the first axis, and the axis of the second connecting shaft 22 is the second axis. Specifically, when the toy car moves forward and backward, the tire 32 rotates relative to the wheel hub 31 around the first connecting shaft 21. When the user's center of gravity deviates to the side, the first wheel 3 rotates left or right around the second connecting shaft 22 under the action of the side force, as shown in FIG. Figure 5 and Figure 6 In the state shown, the first wheel 3 is turned to change the moving direction of the toy car.

[0062] In this embodiment, the first connecting shaft 21 is fixedly connected to the frame 1. Since the second connecting shaft 22 is cross-arranged and rotatably connected to the first connecting shaft 21, and the second connecting shaft 22 is connected to the hub 31 of the first wheel 3, that is, the hub 31 cannot rotate around the first connecting shaft 21, the tire 32 can rotate relative to the hub 31 when the toy car moves with front and rear drive.

[0063] See Figure 1 and Figure 3 The second connecting shaft 22 is perpendicular to the first connecting shaft 21, and the second connecting shaft 22 is tilted toward the second end of the frame 1, ensuring that the tire 32 of the first wheel 3 can generate a return torque on the first wheel 3 when rotating around the first axis, thereby improving the steering stability of the toy car.

[0064] See Figure 2 , the angle between the second connecting axis 22 and the horizontal plane is defined as α, where the value of α ranges from 0° < α < 90°. For example, α can be 45°, 50°, 60°, 70°, etc. In this embodiment, α is 50°. In other embodiments, the inclination angle of the second connecting axis 22 can be adjusted according to design requirements and is not limited to the angle values ​​listed above.

[0065] The larger the value of α, the more flexible and effortless the steering is. Correspondingly, the steering stability of the toy car will decrease. The smaller the value of α, the better the steering stability is and it is easier to maintain a straight line. Correspondingly, the steering resistance will increase.

[0066] like Figure 3 As shown, a first connecting portion 113 and a second connecting portion 114 are spaced apart at the first end of the vehicle frame 1 along the extension direction of the first axis. One end of the first connecting shaft 21 is fixedly connected to the first connecting portion 113, and the other end is fixedly connected to the second connecting portion 114. A rotation space 115 for the first wheel 3 is formed between the first connecting portion 113 and the second connecting portion 114. The fixed connection between the first connecting shaft 21 and the first connecting portion 113 and the second connecting portion 114 prevents the wheel hub 31 from rotating about the first axis, ensuring that the tire 32 can rotate smoothly relative to the wheel hub 31. In addition, the provision of the first connecting portion 113 and the second connecting portion 114 provides space for the tire 32 to rotate about the first connecting shaft 21 and for the first wheel 3 to rotate left and right about the second connecting shaft 22, ensuring smooth movement of the toy vehicle.

[0067] Exemplarily, the first connecting portion 113 and the second connecting portion 114 are both rod-shaped structures, and the first connecting portion 113 and the second connecting portion 114 both extend relative to the frame 1 in a direction facing away from the second end of the frame 1. The extension length of the first connecting portion 113 and the second connecting portion 114 is greater than the outer diameter of the tire 32 of the first wheel 3, ensuring that sufficient space is reserved for the tire 32 to rotate in the horizontal direction.

[0068] Furthermore, the first connecting portion 113 and the second connecting portion 114 are both tilted relative to the frame 1 in a direction away from the ground, which can reserve more space for the tire 32 to rotate in a direction perpendicular to the ground. The ground here refers to the ground on which the first wheel 3 travels when the toy car is in normal use.

[0069] In an alternative embodiment, as 1 and Figure 3 As shown, the first connecting shaft 21 is provided with a fixed sleeve 23 extending along the second axis, the second connecting shaft 22 is inserted into the fixed sleeve 23 and rotates with the fixed sleeve 23, and the inner ring of the wheel hub 31 is provided with a third connecting portion 311 and a fourth connecting portion 312 extending along the radial direction of the wheel hub 31. One end of the second connecting shaft 22 is fixedly connected to the third connecting portion 311, and the other end of the second connecting shaft 22 is fixedly connected to the fourth connecting portion 312. When the center of gravity of the user shifts, the second connecting shaft 22 rotates relative to the fixed sleeve 23 around the second axis under the action of the lateral force, causing the first wheel 3 to deflect to the left or right as a whole (as shown in FIG. Figure 5 and Figure 6 As shown), the moving direction of the first wheel 3 is changed.

[0070] See Figure 1 and Figure 3 The third connecting part 311 and the fourth connecting part 312 are both integrally formed on the connecting seat of the inner ring of the wheel hub 31, and a slot is set on the connecting seat. One end of the second connecting shaft 22 is inserted into the slot of the third connecting part 311, and the other end of the second connecting shaft 22 is inserted into the slot of the fourth connecting part 312. The second connecting shaft 22 and the third connecting part 311 and the fourth connecting part 312 can be fixed by a locking pin, which is convenient for disassembly and assembly, and facilitates the assembly of the wheel hub 31 and the connecting frame 2, thereby improving assembly efficiency.

[0071] For example, a first through hole extending radially through the end of the second connecting shaft 22 is provided, and a second through hole opposite to the first through hole is provided on the third connecting portion 311 and the fourth connecting portion 312. After the second connecting shaft 22 is inserted into the slot, a locking pin is used to pass through the corresponding first through hole and second through hole to fix the second connecting shaft 22 together with the third connecting portion 311 and the fourth connecting portion 312.

[0072] In another alternative embodiment, the second connecting shaft 22 may be disposed through the fixed sleeve 23 and rotatably engaged with the fixed sleeve 23. One end of the second connecting shaft 22 is rotatably connected to the third connecting portion 311, and the other end of the second connecting shaft 22 is rotatably connected to the fourth connecting portion 312. That is, the second connecting shaft 22 is rotatably engaged with both the fixed sleeve 23 and the hub 31 of the first wheel 3. This similarly enables the entire first wheel 3 to deflect by a certain angle about the second connecting shaft 22, thereby changing the direction of movement of the first wheel 3.

[0073] See Figure 1 and Figure 2 The toy car further includes a second wheel 4, which is rotatably disposed at the second end of the frame 2. Figure 2 In the orientation, the first wheel 3 is the front wheel of the toy car, and the second wheel 4 is the rear wheel of the toy car. The movement of the toy car is achieved by driving the first wheel 3 and the second wheel 4 to rotate, and the moving direction of the toy car is adjusted by the first wheel 3.

[0074] In this embodiment, the second wheel 4 is an electric drive wheel, which can realize the automatic movement of the toy car. In other embodiments, the second wheel 4 can also be an ordinary wheel. The user can push the ground forward to help the tire 32 of the first wheel 3 and the second wheel 4 rotate to drive the toy car to move.

[0075] In some embodiments, the first wheel 3 can also be a rear wheel. In this case, the second axis is tilted toward the front of the frame 1, that is, the second connecting shaft 22 is designed to be tilted forward, which can also achieve the change of the moving direction of the toy car through the first wheel 3.

[0076] Optionally, see Figure 4 The first wheel 3 and the second wheel 4 are aligned in the front-to-back direction. This arrangement reduces the risk of loss of control due to a shift in the center of gravity when the toy vehicle encounters bumps or turns during travel, thereby better maintaining the stability of the vehicle. Furthermore, aligning the first and second wheels 3 and 4 simplifies the mechanical structure of the frame 1, reducing design and manufacturing costs and subsequent maintenance.

[0077] Optionally, see Figure 1 、 Figure 2 and Figure 3 The frame 1 includes a fixed frame 11 and a cover plate 12. The cover plate 12 is mounted on the fixed frame 11. The connecting frame 2 is mounted on the first end of the fixed frame 11. The second wheel 4 is rotatably mounted on the second end of the fixed frame 11. The cover plate 12 can provide a stepping space for the user, making it easier to carry the user. On the other hand, it can cover the upper part of the fixed frame 11, making the frame 1 neater and more beautiful. Figure 1 As shown, the middle area of ​​the cover plate 12 is used to support a user.

[0078] See Figure 1 and Figure 3 The fixed frame 11 includes a first section 111 and a second section 112 that are connected and arranged at an angle. The second section 112 is inclined relative to the first section 111, away from the ground. A connecting fork 116 is provided on the second section 112, and the second wheel 4 is rotatably connected to the connecting fork 116 via a third connecting shaft 41. This arrangement allows the rear end of the fixed frame 11 to reserve sufficient vertical space for the second wheel 4. At the same time, the upward tilt of the rear end of the frame 1 enhances the overall aesthetics of the frame 1.

[0079] In this embodiment, Figure 3 As shown, two connecting forks 116 are arranged at intervals on the fixed frame 11 , the second wheel 4 is located between the two connecting forks 116 , the third connecting shaft 41 is coaxially arranged on the second wheel 4 , and both ends of the third connecting shaft 41 are respectively connected to the two connecting forks 116 .

[0080] See Figure 1 and Figure 3 The cover plate 12 includes a first plate segment 121 and a second plate segment 122, which are connected and arranged at an angle. The first plate segment 121 covers the first section 111, and the second plate segment 122 covers the second section 112. The second plate segment 122 is provided with an accommodation space, and the second wheel 4 is partially located within the accommodation space. In other words, the bending direction of the cover plate 12 aligns with the bending direction of the fixed frame 11, allowing the cover plate 12 to fit the fixed frame 11 and ensure the neat appearance of the vehicle frame 1. The provision of the accommodation space prevents the cover plate 12 from interfering with the rotation of the second wheel 4, ensuring smooth movement of the toy vehicle.

[0081] In this embodiment, Figure 1 and Figure 3 As shown, the cover plate 12 is convexly provided in the area corresponding to the second wheel 4 in the direction away from the second wheel 4 to form a bulge 1221, and the bulge 1221 forms the above-mentioned accommodating space on the side facing the second wheel 4, ensuring that the cover plate 12 is a closed structure as a whole, which is relatively neat and beautiful.

[0082] Of course, in other embodiments, a through groove may be provided in the area of ​​the cover plate 12 corresponding to the second wheel 4 so that a portion of the second wheel 4 can rotate in the through groove, thereby ensuring smooth rotation of the second wheel 4 .

[0083] See Figure 3 The fixed frame 11 includes a frame beam 110, and the cover plate 12 is provided with a flange folded toward the frame beam 110 along the circumferential direction, and the flange is buckled outside the frame beam 110. The setting of the flange can make the cover plate 12 better cover the fixed frame 11, making the overall appearance of the frame 1 more neat.

[0084] In this embodiment, the frame beam 110 includes a frame body 1101 and a crossbeam 1102. The cover plate 12 is provided with a first flange 123 at a position corresponding to the frame body 1101, and a second flange 124 at a position corresponding to the crossbeam 1102. Figure 3 As shown, the frame 1101 is a U-shaped frame, and the crossbeam 1102 is fixedly arranged at the opening of the U-shaped frame. The frame 1101 and the crossbeam 1102 are both cylindrical rods. Accordingly, the first flange 123 and the second flange 124 are both arc-shaped flanges, which can better wrap the frame 1101 and the crossbeam 1102, so that there are no sharp parts on the periphery of the frame 1, which is beautiful and safe to use.

[0085] See Figure 3 The two ends of the beam 1102 protrude relative to the frame 1101. Accordingly, a notch is provided at the connection between the first flange 123 and the second flange 124. The notch can avoid the protruding part of the beam 1102 and ensure the fit between the cover plate 12 and the fixed frame 11.

[0086] Furthermore, the first connection portion 113 and the second connection portion 114 are both fixedly arranged on the crossbeam 1102 , and the first connection portion 113 and the second connection portion 114 are substantially on the same extension line as the two straight arms of the U-shaped frame, thereby enhancing the connection stability between the first wheel 3 and the frame 1 .

[0087] See Figure 1 and Figure 2 、 Figure 3 and Figure 7 The toy car also includes an armrest 5, one end of which is movably connected to the frame 1. The armrest 5 has an in-use position and a stowed position. In the in-use position, the armrest 5 is arranged at an angle to the frame 1. In the stowed position, the armrest 5 is closer to the frame 1 relative to the in-use position. When the toy car is not in use, the armrest 5 can be adjusted to the stowed position, bringing the armrest 5 closer to the frame 1, reducing the size of the toy car and making it easier to store or carry. When the toy car is in use, the armrest 5 is adjusted back to the in-use position, and the user can control the toy car by holding the armrest 5.

[0088] In some embodiments, when in the storage position, the armrest 5 fits in with the frame 1 , which can minimize the volume of the toy car after storage, making it easier to store and carry.

[0089] In some embodiments, when in the storage position, the armrest 5 can be moved closer to the frame 1 while maintaining a certain gap between the armrest 5 and the frame 1 , which can reduce the volume of the toy car after storage to a certain extent, making it easier to store and carry.

[0090] Optionally, see Figure 1 、 Figure 3 and Figure 7The armrest 5 includes a rod 51 and a support portion 52. One end of the rod 51 is pivotally connected to one side of the vehicle frame 1, and the support portion 52 is bent and connected to the other end of the rod 51. When in the stowed position, the rod 51 and support portion 52 rotate and abut against the side of the vehicle frame 1. When the toy car needs to be stored or carried, the rod 51 of the armrest 5 can be rotated so that the rod 51 and support portion 52 move toward the vehicle frame 1 and abut against the side of the vehicle frame 1. This can reduce the thickness of the toy car after folding, reducing the space required for storage and making it more convenient to store. The pivotable connection between the rod 51 and the vehicle frame 1 makes folding and unfolding the armrest 5 simpler and more labor-saving.

[0091] The bending connection here means that the supporting portion 52 is bent at a certain angle relative to the rod body 51 and the two are not on the same straight line, that is, the supporting portion 52 and the rod body 51 are arranged at an angle.

[0092] In this embodiment, refer to Figure 3 The support portion 52 and the rod body 51 are approximately at a 90° angle, which is convenient for the user to grasp. Furthermore, the length of the support portion 52 is no greater than the width of the frame 1, which can minimize the width of the toy car after it is folded.

[0093] In some embodiments, the rod body 51 and the supporting portion 52 may be integrally bent and formed, which can simplify the processing steps and reduce the processing cost.

[0094] In some embodiments, the rod body 51 and the supporting portion 52 may be of separate designs, and the rod body 51 and the supporting portion 52 may be separately processed and formed and then assembled together.

[0095] See Figure 3 and Figure 7 The rod 51 bends and extends to correspond to the second section 112 of the fixed frame 11. The curvature of the rod 51 is consistent with that of the fixed frame 11. The connection between the support portion 52 and the rod 51 forms an arc transition. The second end of the frame beam 110 of the fixed frame 11 is curved, and the curvature of the connection between the support portion 52 and the rod 51 is consistent with the curvature of the second end of the frame beam 110. This arrangement allows the support portion 52 and the rod 51 to better fit the side of the vehicle frame 1. When the armrest 5 is folded, it is neater and helps reduce the overall size of the toy vehicle. Furthermore, the armrest 5 has no sharp parts, making it safer to use.

[0096] Exemplarily, a rotating seat is provided at one end of the rod body 51 away from the supporting portion 52 , the end of the beam 1102 of the fixed frame 11 protrudes from the frame body 1101 , and the rotating seat is rotatably connected to the protruding portion of the beam 1102 .

[0097] Furthermore, a locking structure can be provided on the rotating seat. After the position of the armrest 5 is adjusted, the armrest 5 can be locked and fixed by the locking structure to prevent the armrest 5 from rotating during riding, thereby improving riding safety.

[0098] In other embodiments, the rod 51 of the armrest 5 can also be rotatably connected to the middle position of the crossbeam 1102. When the toy car is stored, the armrest 5 is rotated to be close to the top of the cover plate 12 of the frame 1.

[0099] See Figure 3 and Figure 7 A limiting structure 117 is provided on the frame 1. When in the storage position, the armrest 5 is limited to the frame 1 by the limiting structure 117. Fixing the armrest 5 by the limiting structure 117 can prevent the armrest 5 from moving at will, and ensure that the armrest 5 is firmly fixed after storage.

[0100] In this embodiment, the limiting structure 117 is disposed at the rear end of the fixed frame 11. After the armrest 5 is rotated to the storage position, the supporting portion 52 engages with the limiting structure 117. For example, the limiting structure 117 comprises a strip, one end of which is fixedly connected to the frame 1101 of the fixed frame 11 (e.g., welded, bonded, bolted, etc.), and the other end of which is cantilevered and bent upward to form a slot into which the supporting portion 52 can be inserted to secure the supporting portion 52.

[0101] Example 2

[0102] This embodiment provides a toy car, which differs from the first embodiment in that:

[0103] Optionally, the connecting frame 2 includes a first connecting shaft 21 and a second connecting shaft 22 arranged crosswise, both ends of the first connecting shaft 21 are connected to the frame 1, and the wheel hub 31 is coaxial and spaced outside the first connecting shaft 21; the second connecting shaft 22 is fixedly connected to the first connecting shaft 21, and both ends of the second connecting shaft 22 are rotatably connected to the inner ring of the wheel hub 31; the axis of the first connecting shaft 21 is the first axis, and the axis of the second connecting shaft 22 is the second axis. That is, the second connecting shaft 22 and the second connecting shaft 22 are fixed as a whole, and the second connecting shaft 22 is rotatably connected to the wheel hub 31 of the first wheel 3. When the user's center of gravity deviates to the side, the wheel hub 31 rotates left or right relative to the second connecting shaft 22 under the action of the lateral force (such as Figure 5 and Figure 6 As shown), the first wheel 3 is turned to change the moving direction of the toy car.

[0104] Optionally, the first connecting shaft 21 and the second connecting shaft 22 are perpendicular and can be integrally formed. That is, the fixing sleeve 23 in the first embodiment can be omitted, and the first connecting shaft 21 and the second connecting shaft 22 can be directly fixed together. Of course, the second connecting shaft 22 can also be fixed together with the first connecting shaft 21 in a detachable manner.

[0105] like Figure 3 As shown, the inner ring of the hub 31 is provided with a third connecting portion 311 and a fourth connecting portion 312 extending radially along the hub 31. One end of the second connecting shaft 22 is rotatably connected to the third connecting portion 311, and the other end is rotatably connected to the fourth connecting portion 312. For example, a rotation groove can be provided on both the third connecting portion 311 and the fourth connecting portion 312. One end of the second connecting shaft 22 is inserted into the rotation groove of the third connecting portion 311 and rotatably engages therewith, while the other end of the second connecting shaft 22 is inserted into the rotation groove of the fourth connecting portion 312 and rotatably engages therewith.
