Description

Child vehicles Technical Field

[0001] This disclosure relates to a child vehicle. Background Technology

[0002] Currently, commonly used child vehicles generally consist of a vehicle body and a seat mounted on the vehicle body, where the child sits. When the child vehicle is in normal use, the seat is usually fixed relative to the vehicle body, so it cannot be moved to adjust the child's seating space or the distance for interaction with the child. Even if some seats are movable, they still require manual adjustment by the user. Moreover, the seats in current child vehicles have limited functionality and cannot meet the diverse needs of users. Summary of the Invention

[0003] The present disclosure aims to provide a child vehicle with a movable seat that is more human-centered in design and can meet the needs of different users.

[0004] The child vehicle according to this disclosure includes a vehicle body and a seat movement device, wherein the seat movement device includes: a seat movably supported on the vehicle body; a drive mechanism coupled to the seat and capable of driving the seat to move; and a transmission mechanism that drives the seat by means of the transmission mechanism.

[0005] In some embodiments, the transmission mechanism includes one or any combination of a wheel assembly, a multi-link mechanism, a gear set, or a worm gear set.

[0006] In some embodiments, the drive mechanism includes an electrical drive mechanism or a mechanical drive mechanism.

[0007] In some embodiments, the transmission mechanism includes: a first link, the first end of which is rotatably connected to a drive mechanism; and a second link, the first end of which is pivotally connected to a second end of the first link, and the second end of which is pivotally connected to a vehicle body. Through the first link and the second link, the rotational motion of the drive mechanism is converted into the translational motion of the seat.

[0008] In some embodiments, the vehicle body includes a first seat tube arranged and extending along the front-rear direction of the seat portion, the first seat tube being movably mounted on the seat portion, wherein the first seat tube is provided with a guide rail; the seat portion is provided with a first set of rotatable wheels, the first set of wheels being able to roll along the upper side of the guide rail.

[0009] In some embodiments, the seat includes a limiting arm that extends downward from the seat and forms a hook shape, thereby preventing the seat from detaching upward from the guide rail. The limiting arm is provided with a rotatable second set of wheels that can roll along the underside of the guide rail.

[0010] In some embodiments, the drive mechanism is configured to drive the first wheel assembly to move the seat moving device along the first seat tube.

[0011] In some embodiments, the child vehicle further includes a control mechanism for controlling the usage state of the child vehicle, wherein the control mechanism includes: a sensor component for detecting usage information of the child vehicle; and a processing component for receiving and processing the usage information detected by the sensor component.

[0012] In some embodiments, the control mechanism includes a first control box for controlling the drive mechanism and fixing it to the vehicle body.

[0013] In some embodiments, the first control box includes: a first start switch for starting the first control box; and a first control knob for controlling one or more of the sliding speed, amplitude, time, number of times, and frequency of the seat.

[0014] In some embodiments, the vehicle body is provided with adjustment knobs for controlling different modes of the seat.

[0015] In some embodiments, the vehicle body is provided with a handle, which is configured to pivot relative to the vehicle body between a forward position and a reverse position.

[0016] In some embodiments, the handle is configured to trigger a first position switch disposed on the vehicle body when pivoted to the forward position, so that the seat moves to the first position; the handle is configured to trigger a second position switch disposed on the vehicle body when pivoted to the reverse position, so that the seat moves to the second position.

[0017] In some embodiments, the handle is provided with a push portion; when the handle is pivoted to the forward position, the push portion triggers a first position switch; when the handle is switched to the reverse position, the push portion triggers a second position switch.

[0018] In some embodiments, the vehicle body includes a side armrest, which is provided with a third position switch for detecting the reversing action of the handle; when the handle reverses between the forward and reverse positions, the handle passes by and triggers the third position switch, so that the seat moves to the first or second position.

[0019] In some embodiments, the first link is provided with a magnet; the drive mechanism or the base is provided with a first sensor and a second sensor for detecting the position of the magnet; when the base moves to the first position, the position of the magnet corresponds to the first sensor; and when the base moves to the second position, the position of the magnet corresponds to the second sensor.

[0020] In some embodiments, the vehicle body includes a first seat tube and a second seat tube. The first seat tube is arranged and extends along the front-rear direction of the seat portion and is movably mounted on the seat portion. The second seat tube is arranged and extends along the left-right direction of the seat portion and is connected to the first seat tube. The second seat tube is fixedly mounted on the first control box, wherein the first control box includes a connecting post and a transmission mechanism is connected to the connecting post.

[0021] In some embodiments, the first control box includes a mounting end that forms a U-shape with an opening facing the second seat tube, the second seat tube being inserted through the mounting end.

[0022] In some embodiments, the seat moving device further includes a locking part disposed at the U-shaped opening at the mounting end, thereby preventing the first control box from moving forward away from the second seat tube.

[0023] The disclosed solution simplifies the adjustment method of the seat in a child vehicle, allowing users to quickly adjust the seat position not only by adjusting the push button, but also by changing the direction of the handle, thus improving the functionality of the child vehicle.

[0043] To further illustrate the principles and structure of this disclosure, some embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. However, it should be understood that the embodiments described are merely exemplary, and this disclosure should not be construed as limited to the embodiments set forth herein.

[0044] The child vehicles disclosed herein can be strollers, infant carriers, car seats, high chairs, etc., and include movable seats, making the design of the child vehicles more user-friendly and improving their usability and user experience. Furthermore, for ease of understanding and description, the descriptions of front-back, left-right, and up-down directions in this document refer to the orientation of the child vehicle during normal use (for example, the direction the child faces while riding in the vehicle is considered front, and the direction they face away from is considered rear, thus determining left, right, up, and down). It should be understood that this disclosure is not limited to these orientations but can be adjusted according to actual circumstances.

[0045] Figure 1 shows a perspective view of a child vehicle 10 according to the present disclosure, which includes a vehicle body 100 and a seat movement device 200 mounted on the vehicle body 100. Figure 2 also shows a perspective view of the child vehicle 10, except that the seat movement device 200 is presented separately from the vehicle body 100 in Figure 2. Figures 3 to 7 show partial structures of the child vehicle 10 in different views, including the seat movement device 200 and a portion of the vehicle body 100 (specifically, the seat tube, which will be described below).

[0046] Referring to Figures 1 to 7, the seat moving device 200 includes a seat 210, a drive mechanism 220, and a transmission mechanism 230. The seat 210 is movably supported on the carrier body 100 and cooperates with the transmission mechanism 230. The transmission mechanism 230 cooperates with the drive mechanism 220 and is driven by the drive mechanism 220 to move the seat 210.

[0047] Optionally, the seat 210 is designed to be removable from the vehicle body 100, so that different types of vehicles can be replaced on the vehicle body 100 for children of different ages to ride; or the seat 210 may be provided with an adapter so that the seat 210 can also carry different types of vehicles without being removed from the vehicle body 100, for children of different ages to ride.

[0048] According to the child vehicle 10 provided in this disclosure, the seat 210 can cooperate with the transmission mechanism 230, thereby moving under the drive mechanism 220. Therefore, any mechanical mechanism that can receive the driving force provided by the drive mechanism 220 and fully transmit it to the seat 210 to produce displacement can be defined as the transmission mechanism 230 of this disclosure; wherein, the transmission mechanism 230 may be composed of, but is not limited to, one of the wheel assembly, multi-link mechanism, gear set or worm gear set, or any combination thereof.

[0049] In one embodiment, as shown in Figures 1 to 7, the vehicle body 100 may include a first seat tube 110, which is arranged and extends along the front-rear direction of the seat portion 210 (i.e., the front-rear direction of the aforementioned child vehicle 10), such that the seat portion 210 is movably mounted on the first seat tube 110. The seat portion 210 is provided with a rotatable first wheel assembly 211, which is capable of rolling along the upper side of the first seat tube 110.

[0050] Optionally, the first seat tube 110 may be further provided with a guide rail 111. The structure of the guide rail 111 can fully match the structure of the first wheel set 211, so that the first wheel set 211 can not only roll more stably along the upper side of the guide rail 111, but also reduce the consumption of kinetic energy, thereby enabling the first wheel set 211 to move more smoothly on the first seat tube 110.

[0051] In the embodiment shown in Figure 3, the vehicle body 100 may include two first seat tubes 110, located on the left and right sides of the seat portion 210 respectively; correspondingly, the seat portion 210 is provided with first wheel sets 211 on both its left and right sides, thereby making the movement of the seat portion 210 more stable.

[0052] In the embodiments shown in Figures 3-4 and 6-7, specifically, the seat portion 210 includes a limiting arm 213 that extends downward from the seat portion 210 and covers the lower part of the guide rail 111, thereby preventing the seat portion 210 from detaching upward from the guide rail 111. Specifically, the limiting arm 213 first extends downward from the seat portion 210 and then bends to continue extending in the left-right direction. That is, the limiting arm 213 is generally L-shaped, and the horizontal side of the L-shape is located below the first seat tube 110 to prevent the seat portion 210 from accidentally detaching upward from the first seat tube 110, thereby improving safety when using the child vehicle 10. Moreover, the design of the limiting arm 213 helps to improve the overall structural stability of the child vehicle 10, reducing the possibility of the seat portion 210 shifting vertically or horizontally in the event of an accidental impact, thereby ensuring that the child is in a stable and safe environment.

[0053] In an embodiment where the vehicle body 100 includes two first seat tubes 110 respectively disposed on the left and right sides of the seat portion 210, the seat portion 210 is provided with limiting arms 213 on both its left and right sides.

[0054] In addition, the limiting arm 213 can extend further to the outer side of the guide rail 111 and bend upward to cover it after covering the bottom of the guide rail 111, thereby more stably improving the safety of the overall structure of the child vehicle 10.

[0055] Optionally, as shown in Figures 3 to 7, the limiting arm 213 may be provided with a rotatable second wheel assembly 212, which can roll along the lower side of the guide rail 111. Specifically, the horizontal side of the limiting arm 213 has a recess 2131, in which the second wheel assembly 212 is installed. This allows the second wheel assembly 212 to roll along the lower side of the guide rail 111 when the seat 210 moves in the front-back direction, thus making the movement of the seat 210 relative to the first seat tube 110 smoother. Alternatively, the limiting arm 213 may not have a second wheel assembly 212; in this case, the horizontal side of the limiting arm 213 is below the first seat tube 110, and there is a gap between the horizontal side and the first seat tube 110 (i.e., they do not contact each other in the vertical direction), so that no friction occurs between the horizontal side and the first seat tube 110, thus not affecting the movement of the seat 210. The above design can also reduce wear between the seat 210 and the first seat tube 110, extend the service life of the child vehicle 10, and reduce maintenance costs and frequency.

[0056] Additionally, as shown in Figures 3 to 7, the seat 210 may have two first wheel sets 211 on each of its left and right sides, with the two first wheel sets 211 located on either side of the limiting arm 213 along the front-back direction; that is, in the front-back direction of the seat 210, the limiting arm 213 is sandwiched between the two first wheel sets 211. Moreover, when a second wheel set 212 is provided, the two first wheel sets 211 and the second wheel set 212 are arranged in a triangle. Optionally, the second wheel set 212 is located at the midpoint of the connecting line between the two first wheel sets 211. This design makes the movement and adjustment of the seat 210 smoother, providing a smoother and more worry-free user experience.

[0057] In one embodiment, the drive mechanism 220 may be configured to drive the first wheel set 211 to move the entire seat moving device 200 along the first seat tube 110. In this case, the first wheel set 211 is driven by the drive mechanism 220 to move the seat 210; therefore, in this embodiment, the first wheel set 211 is equivalent to the transmission mechanism 230 as defined in this disclosure. With this design, since the drive mechanism 220 can directly drive the first wheel set 211, the entire power transmission is simpler and more reliable, the transmission efficiency is higher, and the overall structure is more compact.

[0058] In some embodiments, as shown in Figures 6 and 7, the transmission mechanism 230 may further include a first link 231 and a second link 232. The first end 2311 of the first link 231 is rotatably connected to the drive mechanism 220; the first end 2321 of the second link 232 is pivotally connected to the second end 2312 of the first link 231; and the second end 2322 of the second link 232 is pivotally connected to the vehicle body 100, or pivotally connected to other components fixed to the vehicle body 100. Through the first link 231 and the second link 232, the rotational motion of the drive mechanism 220 is converted into the translational motion of the seat 210. With this design, since the drive mechanism 220 does not directly drive the first wheel set 211, but sets the first wheel set 211 as a driven wheel, and is paired with the first link 231 and the second link 232 that can extend to the far end, the setting position of the drive mechanism 220 is more flexible, and the entire child vehicle 10 is more compact and compatible in terms of weight distribution or in terms of space combination with other functions.

[0059] It is understood that any mechanism that can drive or move the transmission mechanism 230 to displace the seat portion 210 should be defined as the drive mechanism 220 of this disclosure. Specifically, the drive mechanism 220 can drive the transmission mechanism 230 by means including but not limited to electrical or mechanical drive to drive the seat portion 210 to move in the front-back direction of the child carrier 10. In one embodiment, as shown in FIG14, the drive mechanism 220 can be an electric motor. When the drive mechanism 220 rotates, the first link 231 is driven to rotate by the output shaft 223 of the drive mechanism 220. Due to the pivotal connection between the first link 231 and the second link 232, the rotation of the first link 231 will drive the second link 232 to pivot around the connecting post 242, and the included angle between the two can increase or decrease. Through the operation of the drive mechanism 220 and the connection relationship between the first link 231 and the second link 232, the seat portion 210, on which the drive mechanism 220 is fixedly mounted, can be driven to move back and forth along the first seat tube 110.

[0060] Based on the aforementioned structural foundation of the child vehicle 10, the child vehicle 10 provided in this disclosure may further include a control mechanism.

[0061] It is understood that any mechanism capable of receiving input signals, processing information, and outputting control commands to guide behavior can be defined as the control mechanism of this disclosure. This control mechanism may include hardware, software, or a combination of both. The control mechanism may integrate various sensors, actuators, and communication modules to receive input signals from users, sensors, or other external devices; process the input signals (including logical judgments, mathematical calculations, data analysis, etc.); and convert the processing results into control signals, outputting them to actuators or other system components. In this disclosure, the control mechanism is the core component enabling the seat 210 to move; the control mechanism can output control commands to guide the drive mechanism 220 in driving the seat 210, achieving precise detection and control of the seat 210's position, and providing a user-friendly interface.

[0062] Specifically, as shown in Figures 1-7 and 8-11, the seat moving device 200 may include a first control mechanism, namely, a first control box 240 for controlling the drive mechanism 220. The first control box 240 may include, but is not limited to, one or more of the following components: a power component, a processing component, a sensor component, and a communication component.

[0063] The power assembly provides power to the various components of the control mechanism and may include a power management system, one or more power sources, and any other components associated with the generation, management, and distribution of power in the control mechanism. The power assembly may be configured as a battery module 245; in the embodiments shown in Figures 4 and 6-7, the battery module 245 is mounted inside the first control box 240. However, the battery module 245 may be removable and can be installed separately. For example, when the child carrier 10 is a stroller, the battery module 245 may be separately located on the backrest, above the front wheels, or above the rear wheels of the carrier body 100, preferably near the front or rear wheels. This not only simplifies the seat design and simplifies the seat configuration but also lowers the center of gravity of the frame, resulting in greater stability during use. Of course, this disclosure is not limited to this.

[0064] The processing component controls the overall operation of the first control box 240, such as operations related to the movement nodes, distances, ranges, and frequencies of the base 210. The processing component may include a main control PCBA (printed circuit board) and one or more processors mounted thereon. The main control PCBA (not shown) is installed inside the first control box 240 and is a key component of the first control box 240. As a carrier of electronic components (processors), the main control PCBA precisely connects various components together through conductive lines to form a complete circuit system; this system can realize specific electronic functions according to design requirements. In this disclosure, the processing component can process signals input, for example, from sensor components and communication components, to output control signals to control the drive mechanism 220.

[0065] The processing component provided in this disclosure can control the drive mechanism 220 through a directly input control signal, or receive information from the sensor component through the first control mechanism, generate corresponding instructions through internal calculations, and output information to the drive mechanism 220.

[0066] In one embodiment, as shown in Figures 11 and 12, the handle 300 of the child carrier 10 may be equipped with an adjustment knob 310 for directly adjusting the position of the seat 210 without adjusting the handle position. This adjustment knob 310 (i.e., the seat adjustment knob) may be located on the top portion of the handle 300 for easy user operation. The adjustment knob 310 can achieve different adjustment modes for the seat 210, such as the range or distance of movement of the seat 210 in the forward and backward direction, thereby enabling more flexible adjustment of the seat 210. Such a child carrier 10 also has good adaptability, capable of accommodating children of different ages; that is, by simply adjusting the seat position, it can meet the needs of different growth stages, increasing the versatility and applicability of the design.

[0067] Furthermore, in one embodiment, the child vehicle 10 may be equipped with a sensor assembly, including multiple sensors, to provide status assessments of various aspects of the child vehicle 10. For example, the sensor assembly can detect the seat position, handlebar position, transmission mechanism position, and operating status of the drive mechanism of the child vehicle 10. Among the signal types measured by these sensors, there is information that can be used for processing component operations, and there is also verification-type sensor information that can be used to verify that the current state of the frame conforms to the input information.

[0068] Furthermore, in one embodiment, the child vehicle 10 may also be provided with an adjustment push button 310 that allows the position of the seat 210 to be adjusted directly without adjusting the position of the handle, and a sensor assembly that provides status assessment of various aspects of the child vehicle 10.

[0069] The sensor components mentioned in the foregoing embodiments may include position sensors; for example, in the embodiments shown in Figures 8-10, the sensor components may include one or more of a first position switch 140, a second position switch 150, and a third position switch 160 designed as non-contact inductive switches to detect the position of the handle of the child carrier 10.

[0070] Specifically, referring to Figures 1-2 and 8-9, the child vehicle 10 may include a handle 300, which can be connected to the vehicle body 100 and pivot relative to the vehicle body 100 between a forward position and a reverse position. Figure 8 schematically shows the handle 300 in the forward position; Figure 9 schematically shows the handle 300 in the reverse position, where the forward position means the handle 300 is located at the rear of the child vehicle 10, and the reverse position means the handle 300 is located at the front of the child vehicle 10. When the handle 300 is reversed (i.e., when switching between the forward and reverse positions), the handle 300 can activate the seat movement device 200, which drives the transmission mechanism 230 via the drive mechanism 220 to move the seat 210, thereby adjusting the child's riding space and the interaction distance with the child.

[0071] In the embodiments shown in Figures 11 and 12, the handle 300 may also be provided with a control button 320 for controlling the reversing of the handle 300; specifically, the control button 320 unlocks the handle 300, enabling the handle 300 to pivot between the forward and reverse positions; the control button 320 (i.e., the handle reversing operation element) may be located, for example, on the inner side of one of the left and right sides of the handle 300 to prevent accidental operation.

[0072] Figure 10 shows a perspective view of the child vehicle 10, in which the handle 300 is omitted. As shown in Figure 10, the vehicle body 100 may be equipped with a first position switch 140; when the handle 300 is pivoted to the forward position, the first position switch 140 can detect the handle 300 and then send a signal to the processing component, thereby the first control box 240 controls the drive mechanism 220 to start operating, so that the seat 210 moves to the first position (as shown in Figure 8). Still as shown in Figure 10, the vehicle body 100 may also be equipped with a second position switch 150; when the handle 300 is pivoted to the reverse position, the handle 300 can trigger the second position switch 150 to detect the handle 300, and similarly send a signal to the processing component, thereby the first control box 240 controls the drive mechanism 220 to start operating, so that the seat 210 moves to the second position (as shown in Figure 9).

[0073] In one embodiment, for example, when the child carrier 10 is a stroller, a first position switch 140 may be disposed on the backrest connector of the carrier body 100, and a second position switch 150 may be disposed on the front leg connector of the carrier body 100. Of course, this disclosure is not limited thereto.

[0074] Referring to Figures 8 to 10, the vehicle body 100 may include a side armrest 130, which may be equipped with a third position switch 160 for detecting the reversing action of the handle 300. That is, the vehicle body 100 may only be equipped with the third position switch 160, thereby reducing the number of position switches. Specifically, when the handle 300 pivots between the forward and reverse positions to reverse, the third position switch 160 on the side armrest 130 can detect the passage of the handle 300 and the direction of passage (from front to back or from back to front), and send a signal to the processing component, so that the first control box 240 controls the drive mechanism 220 to start operating, thereby driving the seat 210 to move back and forth to the first position or the second position.

[0075] However, it should be understood that the first position switch 140, the second position switch 150, and the third position switch 160 can also be designed as mechanical trigger switches. In this design, the handle 300 mechanically contacts the first, second, or third position switch when reversing, so that the first control box 240 controls the drive mechanism 220 to start, thereby driving the seat 210 to move. Optionally, as shown in Figure 11 or Figure 12, the handle 300 may be provided with a push portion 340 to facilitate better mechanical triggering of the position switches. When the handle 300 pivots to the forward position, the push portion 340 abuts against and triggers the first position switch 140; when the handle 300 switches to the reverse position, the push portion 340 abuts against and triggers the second position switch 150; or when the handle 300 pivots between the forward and reverse positions for reversing, the push portion 340 passes through and triggers the third position switch 160. Understandably, when the handle 300 abuts against the position switch 140, 150 or 160 via the push part 340, an electrical signal can be sent to the processing component to enable the first control box 240 to control the drive mechanism 220 to start, thereby driving the seat 210 to move back and forth.

[0076] Additionally, the sensor assembly may include a proximity sensor configured to detect the presence of a nearby object without any physical contact. For example, in the embodiment shown in Figures 13-16, the sensor assembly may include a first sensor 260 and a second sensor 270 designed as Hall sensors (but not limited thereto) to detect the seat position of the child vehicle 10.

[0077] As described above, by reversing the handle 300, the seat moving device 200 can be activated, thereby automatically moving the seat 210 to either the first or second position. Figures 13 to 16 show the specific situations of the seat 210 in the first and second positions in cross-sectional views. As shown in Figures 13 and 15, the first connecting rod 231 may be equipped with a magnet 2313; the drive mechanism 220 or the seat 210 may be equipped with a first sensor 260 and a second sensor 270 (schematically shown as being mounted on the drive mechanism 220) for detecting the position of the magnet 2313. Optionally, the first sensor 260 may be located in front of the second sensor 270. When the seat 210 moves to the first position, the position of the magnet 2313 may correspond to the position of the first sensor 260 (as shown in Figure 13); when the seat 210 moves to the second position, the position of the magnet 2313 may correspond to the position of the second sensor 270 (as shown in Figure 15).

[0078] The working mechanism of automatically moving the seat 210 by reversing the handle 300 will be explained in detail below with reference to Figures 8-9 and 13-15. During normal use, the handle 300 is usually in the forward position (i.e., the forward position can be the default mode), at which time the seat 210 is in the first position, as shown in Figure 8. When the handle 300 pivots from the forward position to the reverse position, the handle 300 can trigger the second position switch 150 or the third position switch 160 on the vehicle body 100, thereby receiving an electrical signal to control the start of the drive mechanism 220. Under the drive of the drive mechanism 220, the first link 231 and the second link 232 pivot, and the angle between them increases; or, as shown in the side cross-sectional views of Figures 13 and 15, the overlap section of the first link 231 and the second link 232 in the vertical direction gradually decreases. By pivoting the first link 231 and the second link 232, the drive mechanism 220 and the seat 210 fixedly connected to it move forward as a whole from the first position. During this process, as the first link 231 pivots forward and the drive mechanism 220 and the seat 210 move forward, the magnet 2313 on the first link 231 changes from corresponding to the first sensor 260 to corresponding to the second sensor 270. When the second sensor 270 detects the magnet 2313, the drive mechanism 220 is controlled to stop operating. In this way, the seat 210 moves from the first position to the second position and remains in the second position, as shown in Figures 9, 15, and 16. Moreover, as can be seen from the top cross-sectional view in Figure 16, when the seat 210 is in the second position, the first link 231 is located in front of the second link 232.

[0079] Conversely, when the handle 300 pivots from the reverse position to the forward position, it can trigger either the first position switch 140 or the third position switch 160 on the vehicle body 100, thereby receiving an electrical signal to control the drive mechanism 220 to start. Driven by the drive mechanism 220, the first link 231 and the second link 232 pivot, and the angle between them decreases. Through the pivoting of the first link 231 and the second link 232, the drive mechanism 220 and its fixedly connected seat 210 move backward as a whole from the second position. During this process, as the first link 231 pivots backward and the drive mechanism 220 and seat 210 move backward, the magnet 2313 on the first link 231 changes from corresponding to the second sensor 270 to corresponding to the first sensor 260. When the first sensor 260 detects the magnet 2313, the drive mechanism 220 is controlled to stop operating. Thus, the seat 210 moves from the second position to the first position and remains in the first position, as shown in Figures 8, 13 and 14.

[0080] Therefore, through the combined action of magnet 2313, first sensor 260, and second sensor 270, seat 210 can automatically adjust to an accurate and suitable position when handle 300 is reversed. Automatic adjustment not only ensures that children are always in a safe and comfortable sitting posture but also reduces safety hazards caused by improper manual adjustment.

[0081] In some embodiments, the sensor assembly may further include a speed sensor to detect the speed of the drive mechanism 220. As shown in Figures 13 and 15, the seat moving device 200 is provided with a speed sensor 280 for detecting the rotational speed of the drive mechanism 220. In some embodiments, as shown in Figures 13 to 16, the drive mechanism 220 may include a motor 221, a gear 222, and an output shaft 223. The speed sensor 280 may be disposed below the motor 221 and may be a grating detection sensor. The gear 222 is disposed between the motor 221 and the output shaft 223, and optionally, the gear 222 may be configured as a reducer. The first end 2311 of the first connecting rod 231 is rotatably sleeved on the output shaft 223, and the second end 2312 of the first connecting rod 231 is rotatably inserted into the first end 2321 of the second connecting rod 232. Furthermore, as shown in Figure 7, the bottom of the seat 210 may be provided with a fixing part 214, so that the drive mechanism 220 is mounted to the seat 210 through the fixing part 214. This disclosure does not impose a specific limit on the number of fixed parts 214.

[0082] The communication component is configured to facilitate wired or wireless communication between the first control box 240 and other devices. The devices can access wireless networks based on communication standards such as Wi-Fi, 2G, 3G, 4G, or 5G, or combinations thereof. In one exemplary embodiment, the communication component includes a Near Field Communication (NFC) module to facilitate short-range communication. For example, the NFC module can be implemented based on Radio Frequency Identification (RFID) technology, Infrared Data Association (IrDA) technology, Ultra Wideband (UWB) technology, Bluetooth (BT) technology, and other technologies. In this disclosure, the first control box 240 can communicate with a remote control or a mobile app (e.g., via Bluetooth) through the wireless communication module, allowing the user to turn the first control box 240 on or off using the remote control or mobile app. Furthermore, the remote control and mobile app can integrate various smart functions of the child vehicle 10, providing more comprehensive control options.

[0083] In addition to the method of starting the first control box 240 by changing the handle 300 as described above, as shown in Figures 3 and 5, the first control box 240 may also be equipped with a first start switch 243 and a first control knob 244. The first start switch 243 is used to start the first control box 240, and the first control knob 244 is used to control one or more of the following: the moving speed, amplitude, time, number of times, and frequency of the seat 210.

[0084] With the first start switch 243 provided, the seat moving device 200 according to this disclosure can also cause the seat 210 to reciprocate in the front-to-back direction to achieve the function of a rocking chair. Specifically, when the user wants the seat 210 to function as a cradle, the first start switch 243 can be turned on, causing the first control box 240 to control the drive mechanism 220 to operate continuously, thereby driving the seat 210 to reciprocate in the front-to-back direction. Moreover, the user can operate the first control knob 244 to control one or more of the following: the moving speed, amplitude, time, number of times, and frequency of the seat 210, so as to make the movement of the seat more comfortable and more user-friendly. Optionally, there can be two first control knobs 244 to realize different modes of electric rocking function. In this way, a child carrier can be used for multiple purposes, realizing functional diversification and saving consumer costs.

[0085] The installation method of the first control box 240 will be described below.

[0086] Referring to Figures 1 to 7, the vehicle body 100 may further include a second seat tube 120, which is arranged and extends along the left-right direction of the seat portion 210 and is connected to the first seat tube 110. In the embodiments shown in Figures 6 and 7, the first control box 240 is located below the drive mechanism 220 and the transmission mechanism 230 and is fixed to the second seat tube 120. Specifically, the first control box 240 may include a mounting end 241 (e.g., the rear end shown in Figures 4-6 and Figures 13 and 15), which forms a U-shape with an opening facing the second seat tube 120. The second seat tube 120 passes through the U-shaped mounting end 241, thereby mounting the first control box 240 on the second seat tube 120. In addition, the seat moving device 200 may also include a locking part 290, which is provided at the U-shaped opening of the mounting end 241 to prevent the first control box 240 from disengaging forward from the second seat tube 120. Alternatively, the first control box 240 can also be mounted on the back of the child vehicle 10 for easy operation by the user.

[0087] In some embodiments, as shown in Figures 6 and 7, the second end 2322 of the second link 232 is pivotally connected to a first control box 240 mounted on a second seat tube 120 of the vehicle body 100. For example, the first control box 240 may include a connecting post 242 on which the second end 2322 of the second link 232 is rotatably sleeved. It is understood that the first control box 240 and its connecting post 242 are stationary relative to the vehicle body 100.

[0088] In other embodiments, the second end 2322 of the second link 232 can be pivotally connected directly to the second seat tube 120 mounted on the vehicle body 100. This disclosure does not limit the specific manner of the pivotal connection. In this case, the first control box 240 can be installed in other locations on the child vehicle 10, such as to the backrest as described above. This design not only simplifies the connection of the transmission mechanism 230 and makes it easier to maintain, but also makes the installation of the first control box 240 more flexible.

[0089] Additionally, in the embodiments shown in Figures 4-7 and 13-16, the seat movement device 200 may further include a second control mechanism, namely, a second control box 250. Similar to the first control box 240, the second control box 250 may also include, but is not limited to, processing components, power components, and communication components. In this disclosure, the second control box 250 may include a vibration module (e.g., a vibrator) and a sound module (e.g., a speaker) to implement vibration and music box functions. For example, the second control box 250 may alert the user by vibration or sound when the seat 210 moves to the appropriate position; or, for example, when the seat movement device 200 activates the rocking chair function, the music module may play various music and sound effects to attract the child's attention or soothe a crying child, thereby enhancing the functionality of the child vehicle.

[0090] As shown in Figures 4-7 and 13-16, the second control box 250 can be installed on the second seat tube 120 of the vehicle body 100. Optionally, the second control box 250 may also be equipped with a second start switch 251 for activating the second control box 250. Furthermore, the second control box 250 may also be equipped with a second control knob 252 for adjusting and controlling the vibration amplitude and music volume. The second control box 250 provides a reminder and feedback function for the movement adjustment of the seat 210, and also increases the fun of use. Of course, it is understood that the vibration module and sound module of the second control box 250 can be integrated into the first control box 240, thus eliminating the need for the second control box 250 in the child vehicle 10, resulting in a more compact overall structure.

[0091] Furthermore, the child carrier 10 may also be provided with a release button 330 to allow the child carrier 10 to be unfolded and folded. In one embodiment, as shown in Figures 11 and 12, the release button 330 (i.e., the folding release button) may be located, for example, at the top of the handle 300 for easy operation by the user. Moreover, the release button 330 may be located near the aforementioned adjustment push button 310, so that the functional layout of the handle 300 is more compact.

[0092] In summary, the child carrier 10 disclosed herein includes a reversible handle 300 and a movable seat 210. Therefore, the child carrier 10 not only supports bidirectional use but also automatically adjusts the seat 210 to an appropriate position when the handle 300 is reversed. This allows parents to easily adjust the position of the seat 210 to adapt to different usage scenarios and the required interaction distance with the child, thereby increasing parent-child interaction and facilitating parental observation and care. Furthermore, the child carrier 10 disclosed herein also integrates the function of a rocking chair, i.e., the seat 210 can move back and forth, thereby increasing the versatility of the child carrier 10 and improving its usability and user experience.
