[0079] It should be understood that throughout the drawings, like reference numerals refer to like components, parts and structures.

[0080] The contents of the detailed structure and assembly defined in this specification are merely intended to help comprehensively understand the embodiments of the present disclosure. Therefore, it should be understood by those skilled in the art that various changes and modifications can be made to the embodiments described herein without departing from the scope and spirit of the present disclosure. Therefore, descriptions of well-known functions and structures are omitted for clarity and conciseness.

[0081] The present disclosure is intended to improve the steering control performance of a child carrier and / or enhance various electrical functions of the child carrier. In various embodiments of the present disclosure described below, a child tricycle is used as an example of a child carrier for illustrative purposes, but the present disclosure is not limited thereto. The child carrier involved in the present disclosure may be various strollers having wheels for pushing and / or pedaling.

[0082] A child carrier 100 according to various embodiments of the present disclosure will now be described in detail with reference to FIGS.

[0083] 1 to 4 schematically show a child carrier 100 according to a first embodiment of the present disclosure. The child carrier 100 includes a frame body 10, a leading assembly 20 directly and / or indirectly connected to the frame body 10, a front wheel assembly 30, a rear wheel assembly 40, and a seat 50.

[0084] The leading assembly 20 and the front wheel assembly 30 are rotatably connected to a first connecting member 11 that is fixedly connected to the frame body 10. Thus, the leading assembly 20 and the front wheel assembly 30 are connected to the frame body 10 via the first connecting member 11 in a synchronously or separately rotatable manner. When the front wheel assembly 30 is moved forward or rearward by pushing or pedaling the child carrier 100, the first connecting member 11 drives the frame body 10 and the rear wheel assembly 40 to move forward or rearward together. The rear wheel assembly 40 may be directly and fixedly connected to the frame body 10. The seat 50 may be fixedly or detachably disposed on the frame body 10.

[0085] 1 and 2, in at least one embodiment according to the present disclosure, the first connecting member 11 is configured to rotatably connect the leading assembly 20 and the front wheel assembly 30 to the frame main body 10. Specifically, as shown in FIGS. 1 and 2, the front wheel assembly 30 has a front wheel 31 and a front fork 32, which is coaxially connected to the leading assembly 20 and configured to be selectively fixedly or rotatably connected to the leading assembly 20, and the first connecting member 11 includes a tubular connecting portion 111 and at least one connecting rib 112, which is rotatably connected to the rotating bases 322 (see FIG. 8) of the leading assembly 20 and the front fork 32, and the at least one connecting rib 112 is connected between the tubular connecting portion 111 and the frame main body 10. In addition, the child carrier 100 may further include a push rod 60 rotatably arranged at the rear end of the frame body 10, a towing assembly 70 (see FIG. 4) connected between the push rod 60 and the front wheel assembly 30, an unlocking assembly 80 arranged between the leading assembly 20 and the front wheel assembly 30, and a backrest assembly 90 arranged on the rear side of the seat 50.

[0086] As shown in FIGS. 1 to 5, the backrest assembly 90 is connected to the frame body 10 via a connecting bracket 91. Additionally, the backrest assembly 90 includes an armrest frame 92 connected to the connecting bracket 91. The top end of the backrest assembly 90 includes a foldable sunshade assembly 95. The sunshade assembly 95 includes a foldable sunshade frame connected to the top end of the backrest assembly 90. A sunshade cloth may cover the sunshade frame.

[0087] As shown in FIGS. 1 and 2 , the rear wheel assembly 40 includes a rear wheel 41 and a rear wheel stand 42, and the rear wheel stand 42 is fixedly connected to the frame body 10. In at least one embodiment according to the present disclosure, the child carrier 100 includes a front wheel assembly 30 and two rear wheel assemblies 40. In addition, the two rear wheel stands 42 may be fixedly connected to the frame body 10, respectively, or may be integrally formed and fixedly connected to the frame body 10. In at least one embodiment according to the present disclosure, the rear wheel assembly 40 may have a structure similar to the front wheel assembly and may be connected to the frame body 10 via an additional rear wheel stand. The number of front wheel assemblies 30 and rear wheel assemblies 40 may be changed according to specific design requirements of the child carrier and is not limited to one front wheel assembly and two rear wheel assemblies.

[0088] 3 and 4 are bottom views of a child carrier 100 according to various embodiments of the present disclosure. The child carrier 100 shown in Fig. 3 includes a cover plate 13 on the bottom that covers the towing assembly 70 to prevent the towing assembly 70 from accidentally falling. The cover plate 13 is removed from the bottom of the child carrier 100 shown in Fig. 4, thereby exposing the towing assembly 70.

[0089] As shown in FIG. 4 , in at least one embodiment according to the present disclosure, the traction assembly 70 is disposed on the bottom side of the frame body 10 and includes a two-way traction member located between the pair of rear wheel assemblies 40. The two-way traction member may be, for example, a two-way traction cable 71 (see FIGS. 12 and 13 ). The two-way traction cable 71 may be a traction member having a specific flexibility, such as a steel wire rope, a chain, a metal chain, a metal wire, or a rope with a low elastic modulus. Herein, the two-way traction member may drive the front wheel assembly 30 to pivot in different rotational directions (clockwise or counterclockwise) relative to the frame body 10 about an axis that passes vertically through the rim of the front wheel 31. In this manner, the front wheel assembly 30 may be pivoted left and right by using the push rod 60 to control the forward direction of the child carrier 100.

[0090] 3 and 17, the cover plate 13 may include a first cover plate 131 and a second cover plate 132. The second cover plate 132 covers the bottom side of the frame body 10, and the first cover plate 131 covers only the bottom end surface of the push rod 60 or only the bottom side of the second connecting member 12. The first cover plate 131 and the second cover plate 132 may be arranged separately or may be integrally formed.

[0091] As shown in FIGS. 5 to 7, FIG. 5 is a perspective view of the child carrier 100 according to an embodiment of the present disclosure, in which the first connecting member 11 and the cover plate 13 have been removed, and the connection relationship between the front wheel assembly 30 and the leading assembly 20 is shown. FIG. 6 schematically shows a perspective view of the child carrier according to an embodiment of the present disclosure, in which the seat 50 has been removed and the unlocking assembly 80 is in the unlocked position. In this case, the leading assembly 20 and the front wheel assembly 30 each correspond to a different orientation. FIG. 7 schematically shows a perspective view of the child carrier 100 shown in FIG. 6 in another state, in which the leading assembly 20 and the front wheel assembly 30 each correspond to the same orientation.

[0092] In at least one embodiment according to the present disclosure, the push rod 60 is connected to the frame body 10 via the second connecting member 12. That is, as shown in FIGS. 5 to 7 , the second connecting member 12 is connected to the frame body 10, and the lower portion of the push rod 60 is rotatably inserted into the second connecting member 12 and connected to the traction assembly 70 to control the steering of the nose wheel assembly 30 or both the nose wheel assembly 30 and the leading assembly 20.

[0093] In at least one embodiment according to the present disclosure, due to the structural characteristics of the frame body 10 and the rear wheel assembly 40, one portion of the second connecting member 12 is connected to the pair of rear wheel stands 42, and the other portion is connected to the frame body 10. That is, the second connecting member 12 may be configured to connect the push rod 60 to the frame body 10 and the rear wheel assembly 40 (specifically, the rear wheel stands 42).

[0094] 5, the front fork 32 further includes a pair of fork arms 321 and a rotating base 322 connected between the pair of fork arms 321. Each pair of fork arms 321 is configured to be coupled to two opposite sides of the front wheel 31. The rotating base 322 is connected between the pair of fork arms 321 and is selectively rotatably or fixedly connected to the leading assembly 20. The pair of fork arms 321 may be formed separately or integrally.

[0095] 8-9, more specifically, the rotating base 322 is selectively rotatably or fixedly connected to the lower end of the leading assembly 20 via the unlocking assembly 80. Figure 8 is a schematic, partially exploded perspective view of a child carrier according to another embodiment of the present disclosure, in which the leading assembly is in a partially exploded state and the first connecting member has been removed. Figure 9 is a partial enlarged view of C in Figure 8.

[0096] 8 and 9, it should be noted that leading assembly 20 includes handlebar assembly 21 having handlebar 211 and connection portion 212 extending downward from a central portion of handlebar 211, and connection assembly 22 configured to support unlocking assembly 80, fixedly connected to connection portion 212 of handlebar assembly 21 and rotatably connected to rotating base 322. Connection assembly 22 includes support frame 221 and gland 231. Gland 231 may be detachably connected to support frame 221 or fixedly connected to support frame 221. Unlocking assembly 80 is slidably disposed between gland 231 and support frame 221.

[0097] 8 and 9, in at least one embodiment according to the present disclosure, the support frame 221 includes a connecting pipe 223 located at the bottom of the support frame 221, a lamp support portion 225 located at the top of the support frame 221, a locking member support portion 224 located at the center of the support frame 221, and a hollow connecting shaft 222 located at the center of the connecting pipe 223. The locking member support portion 224 includes a support protrusion 201 (see FIGS. 12 and 13) and is connected to the ground 231 and the connecting portion 212. However, the present disclosure is not limited thereto.

[0098] 7 to 9, the upper end and / or the lower end of the tubular connecting portion 111 of the first connecting member 11 may be connected to the upper end of the connecting pipe 223 and the lower end of the rotating base 322 via a connecting ring 241, respectively. In some embodiments according to the present disclosure, the connecting ring 241 may be an annular member having a screw thread. In some embodiments according to the present disclosure, the connecting ring 241 may alternatively be a seal ring for achieving the dual functions of shock absorption and sealing.

[0099] 10-14, the specific structures of the unlocking assembly 80, the leading assembly 20, and the front fork 32, as well as the locking and unlocking principles of the unlocking assembly 80, will be described in more detail. FIG. 10 is a longitudinal cross-sectional view of the child carrier shown in FIG. 8, where the leading assembly 20 is in an assembled state and the unlocking assembly 80 is in a locked position. FIG. 11 is a longitudinal cross-sectional view of the child carrier shown in FIG. 8, where the leading assembly 20 is in an assembled state and the unlocking assembly 80 is in an unlocked position. FIG. 12 is a partial enlarged view of E in FIG. 10. FIG. 13 is a partial enlarged view of D in FIG. 11. FIG. 14 is a perspective view of a front fork according to an embodiment of the present disclosure, where the housing of the fork arm 321 of the front fork 32 has been removed.

[0100] The unlocking assembly 80 has a locked position P1 (see FIG. 12) and an unlocked position P2 (see FIG. 13). In the locked position P1, the leading assembly 20 and the nose wheel assembly 30 are locked in the circumferential direction and rotate synchronously. In the unlocked position P2, the leading assembly 20 and the nose wheel assembly 30 are rotatably connected, thereby allowing the leading assembly 20 and the nose wheel assembly 30 to rotate independently.

[0101] More specifically, when the unlocking assembly 80 is in the unlocked position P2, the rotating base 322 is rotatably connected to the lower end of the leading assembly 20, such that the leading assembly 20 no longer controls the steering of the nose wheel assembly 30, and the steering of the nose wheel assembly 30 can be controlled only by the push rod 60 via the traction assembly 70 (two-way traction cable 71). When the unlocking assembly 80 is in the locked position P1, the rotating base 322 and the lower end of the leading assembly 20 are locked in the circumferential direction and rotate synchronously, such that both the leading assembly 20 and the push rod 60 can control the steering of the nose wheel assembly 30.

[0102] 8 shows child carrier 100 with unlocking assembly 80 in locked position P1. In this case, lead assembly 20 and front wheel assembly 30 can rotate synchronously. In this case, both the child pedaling child carrier 100 and the child caretaker pushing child carrier 100 can control the direction of front wheel assembly 30, with the direction of rotation of front wheel assembly 30 ultimately determined by the party applying the greater force.

[0103] FIG. 6 shows the child carrier 100 with the unlocking assembly 80 in the unlocked position P2. In this case, the lead assembly 20 and the front wheel assembly 30 may rotate asynchronously. That is, when the unlocking assembly 80 is in the unlocked position P2, the lead assembly 20 can no longer control the steering of the front wheel assembly 30; the rotation direction of the front wheel assembly 30 can only be changed by controlling the push rod 60. In this case, the user can change the forward direction of the front wheel assembly 30 by rotating the push rod 60, while the child can continue to operate the lead assembly 20, without affecting each other. As shown in FIG. 6, the direction of the lead assembly 20 and the direction of the front wheel assembly 30 are not consistent. The lead assembly 20 may be controlled by the child pedaling the child carrier 100, and the front wheel assembly 30 may be controlled by the person caring for the child pushing the child carrier 100.

[0104] 12 and 13, the unlocking assembly 80 includes a locking member 81, which is slidably disposed on the support frame 221 of the leading assembly 20, and has a locking pin 82 and an operating portion 83 disposed on the locking pin 82. The operating portion 83 is exposed through an opening 232 (for example, FIG. 9) in the gland 231 for user operation.

[0105] The unlocking assembly 80 further includes an elastic member 84. The elastic member 84 is configured to include a first fixed end 85 and a second fixed end 86 fixed to the upper and lower ends of the operating portion 83, respectively, and a bent elastic body 87 located between the first fixed end 85 and the second fixed end 86. The elastic body 87 includes a first portion 88 and a second portion 89, and a support protrusion 201 is provided on the support frame 221 of the leading assembly 20 at a position corresponding to the elastic body 87.

[0106] 12, when the locking member 81 is in the locked position P1, the support protrusion 201 abuts against the first portion 88 and applies a downward elastic force to the locking member 81. As shown in FIG. 13, when the locking member 81 is in the unlocked position P2, the support protrusion 201 abuts against the second portion 89 and applies an upward elastic force to the locking member 81. Because the locking member 81 receives the elastic force of the elastic member 84 in both the locked position P1 and the unlocked position P2, the unlocking assembly 80 can be maintained in the locked position P1 or the unlocked position P2 without being automatically reset.

[0107] In this manner, by operating the operating unit 83 to slide the locking member 81 downward against the elastic force of the elastic member 84, the unlocking assembly 80 can be moved from the unlocked position P2 to the locked position P1. As shown in FIG. 12 , when the unlocking assembly 80 is in the locked position P1, the locking pin 82 is inserted vertically into the pin hole 325 formed in the rotating base 322, thereby locking the lead assembly 20 and the front wheel assembly 30 in the circumferential direction and causing them to rotate synchronously. By operating the operating unit 83 to slide the locking member 81 upward against the elastic force of the elastic member 84, the unlocking assembly 80 can be moved from the locked position P1 to the unlocked position P2. At the unlocked position P2, the locking pin 82 is disengaged from the pin hole 325, thereby releasing the circumferential lock between the lead assembly 20 and the front wheel assembly 30. In this manner, the lead assembly 20 and the front wheel assembly 30 are rotatably connected to each other so that they can rotate independently of each other. That is, rotating the lead assembly 20 no longer drives the front wheel assembly 30 to rotate.

[0108] In at least one embodiment according to the present disclosure, the elastic member 84 may be a spring plate having a curved shape and is pressed between the support protrusion 201 and the locking member 81. In at least one embodiment according to the present disclosure, one side of the support protrusion 201 is configured to support the first portion 88 and apply a downward elastic force to the locking member 81, and the other side of the support protrusion 201 is configured to support the second portion 89 and apply an upward elastic force to the locking member 81.

[0109] 12-14 , in at least one embodiment according to the present disclosure, the front fork 32 further includes a stepped connecting hole 326 disposed at the center of the rotating base 322, and the connecting shaft 222 is inserted into the stepped connecting hole 326. The front fork 32 further includes a rotary peg 328 and a fastening assembly 329, and the rotary peg 328 is inserted into the stepped connecting hole 326 through the central hole 228 of the connecting shaft 222, thereby rotatably and axially connecting the front fork 32 and the leading assembly 20. Thus, the front wheel assembly 30 and the leading assembly 20 can be axially connected to eliminate or reduce axial movement of the leading assembly 20.

[0110] Additionally, as shown in FIG. 14 , the rotating base 322 further includes a limiting protrusion 327 disposed adjacent to the pin hole 325. In at least one embodiment according to the present disclosure, the limiting protrusion 327 is located between the pin hole 325 and the stepped connecting hole 326. Accordingly, as shown in FIGS. 12 and 13 , a pair of stop ribs 229 spaced apart from each other in the circumferential direction is also provided in the connecting tube 223. The pair of stop ribs 229 is connected between the connecting tube 223 and the connecting shaft 222, and the circumferential angle between the pair of stop ribs 229 corresponds to the rotation range of the leading assembly 20. That is, when the unlocking assembly 80 is in the unlocked position P2, the pair of stop ribs 229 respectively define a left stop point for left rotation and a right stop point for right rotation of the nose wheel assembly 30 relative to the leading assembly 20. In some embodiments according to the present disclosure, when the unlocking assembly 80 is in the locked position P1, the rotation angles of the nose wheel assembly 30 and the leading assembly 20 can be limited via the first connecting member 11.

[0111] The detailed structure of the traction assembly 70 in accordance with at least one embodiment of the present disclosure is described in detail below with reference to FIGS.

[0112] As described above, the traction assembly 70 includes a two-way traction cable 71 connected between the rotating base 322 and the push rod 60. In at least one embodiment according to the present disclosure, as shown in FIG. 15 , the traction assembly 70 further includes end coupling protrusions 72 and 74 disposed at the two ends of the bi-directional traction cable 71 and an intermediate coupling protrusion 73 disposed on a central section of the bi-directional traction cable 71. The end coupling protrusions 72 and 74 engage with one of the push rod 60 and the front fork 32 (specifically, the rotating base 322), and the intermediate coupling protrusion 73 engages with the other of the push rod 60 and the front fork 32 (specifically, the rotating base 322), around which the bi-directional traction cable 71 is attached. One of the rotating base 322 and the push rod 60 has a first positioning structure, and the other has a second positioning structure, the first positioning structure adapted to fix the end coupling protrusions 72 and 74 of the two-way traction cable 71, and the second positioning structure adapted to fix the middle coupling protrusion 73 of the two-way traction cable 71.

[0113] More specifically, one of the end coupling projections 72 and 74 and the intermediate coupling projection 73 may engage with the bottom end surface or outer peripheral surface of the push rod 60, and the other of the end coupling projections 72 and 74 and the intermediate coupling projection 73 may be attached to the outer peripheral surface of the rotating base 322.

[0114] 14 , the first positioning structure is provided on a surface (e.g., a side surface) of the rotating base 322, and the first positioning structure may be a mounting groove 323 and end engagement grooves 324 located at two ends of the mounting groove 323. The mounting groove 323 is adapted to mount the two-way pull cable 71, and the end engagement grooves 324 are adapted to engage with the end coupling protrusions 72 and 74. In at least one embodiment according to the present disclosure, the depth of each of the end engagement grooves 324 is greater than the depth of the mounting groove 323 and / or the width of each of the end engagement grooves 324 is greater than the width of the mounting groove 323.

[0115] 16 , accordingly, the push rod 60 (e.g., on the bottom end surface or side surface) further includes a second positioning structure. The second positioning structure is, for example, an annular mounting groove 64 and an intermediate engagement groove 65 located within the annular mounting groove 64. The annular mounting groove 64 is adapted to mount a two-way traction cable 71, and the intermediate engagement groove 65 is adapted to engage with an intermediate coupling protrusion 73. In at least one embodiment according to the present disclosure, the depth of the intermediate engagement groove 65 is greater than the depth of the annular mounting groove 64 and / or the width of the intermediate engagement groove 65 is greater than the width of the annular mounting groove 64.

[0116] However, the present disclosure is not limited to the above. For example, alternatively, the two-way pull cable 71 may be mounted in the opposite direction. That is, the push rod 60 further includes a mounting groove 323 and end engagement grooves 324 located at two ends of the mounting groove 323. The mounting groove 323 is adapted to mount the two-way pull cable 71, and the end engagement grooves 324 are adapted to engage with the end coupling protrusions 72 and 74. In at least one embodiment according to the present disclosure, the depth of each of the end engagement grooves 324 is greater than the depth of the mounting groove 323 and / or the width of each of the end engagement grooves 324 is greater than the width of the mounting groove 323.

[0117] Accordingly, the rotating base 322 further includes an annular mounting groove 64 and an intermediate engagement groove 65 located within the annular mounting groove 64. The annular mounting groove 64 is adapted to mount the two-way pull cable 71, and the intermediate engagement groove 65 is adapted to engage the intermediate coupling protrusion 73. In at least one embodiment according to the present disclosure, the depth of each of the intermediate engagement grooves 65 is greater than the depth of the annular mounting groove 64 and / or the width of each of the intermediate engagement grooves 65 is greater than the width of the annular mounting groove 64.

[0118] In the above embodiment, the method of connecting the two-way traction cable 71 to the front fork 32 and the push rod 60 has been described using an engagement structure, but the present disclosure is not limited thereto. For example, the two-way traction cable 71 may be connected to the front fork 32 and the push rod 60 in a variety of other fixed or detachable connection methods, such as threaded connection, welding, riveting, and dovetail connection, as long as the connection can ensure that when the push rod 60 rotates, steering of the front wheel assembly 30 can be driven via the two-way traction cable 71. All of these may be considered within the scope of the present disclosure.

[0119] Because the two-way traction cable 71 of the traction assembly 70 may apply stress to components that contact the two-way traction cable 71 during a traction operation, to eliminate such stress, in at least one embodiment according to the present disclosure, the traction assembly 70 may further include a sheath 75 and at least one protective clamp 76, as shown in FIGS. 15-17 . The sheath 75 encases portions of the two-way traction cable 71 other than the portions connected to the push rod 60 and the front fork 32. The at least one protective clamp 76 is disposed on an end of the sheath and is clamped within the first connecting member 11 and / or the second connecting member 12.

[0120] 16 , the second connecting member 12 has a through hole 121 for accommodating the push rod 60, and a pair of spaced apart snap protrusions 122 are disposed at the bottom end of the through hole 121 to restrain the bottom end of the push rod 60 and particularly prevent the two-way pull cable 71, the middle coupling protrusion 73, or the end coupling protrusions 72 and 74 from accidentally detaching from the push rod 60. The above-mentioned first cover plate 131 and second cover plate 132 can further prevent the two-way pull cable 71 from accidentally dropping off.

[0121] Additionally, in at least one embodiment according to the present disclosure, the fork arm 321 of the front fork 32 may include a main body portion (shown in FIG. 14 ) and a housing coupled to the main body portion (the housing is removed in FIG. 14 ). Thus, a space for accommodating electrical-related devices such as the electrical wires 501, rectifier 530, USB interface, switch device, battery, and charging port, which will be described in detail below, may be defined between the main body portion of the fork arm 321 and the housing. Additionally, if necessary, in at least one embodiment according to the present disclosure, alternatively or in addition, a cavity for accommodating the electrical wires 501, rectifier 530, USB interface, switch device, battery, and charging port, etc., which will be described in detail below, may be formed in the bottom of the rotating base 322.

[0122] As shown in FIGS. 18 to 21 , the child carrier 100 includes a light-emitting device 140. The light-emitting device 140 can be used as a lighting lamp for the child carrier 100 to provide illumination for children playing at night. The light-emitting device 140 and a switch 141 for the light-emitting device 140 (see FIGS. 19 and 20 ) are located on the front and rear sides of the front assembly 20, respectively. More specifically, the light-emitting device 140 and the switch 141 can be disposed at the intersection of the two handlebars 211 of the front assembly 20. In addition, as shown in FIG. 19 , a reflective sheet 142 that reflects light from the light-emitting device 140 can be disposed around the light-emitting device 140. The light-emitting device 140 can be, for example, an LED lamp. The reflective sheet 142 can be, for example, a chrome-plated reflective sheet.

[0123] Additionally, child carrier 100 may further include an electronic sound-generating module (not shown) and / or a rechargeable battery (not shown). Accordingly, child carrier 100 may further include a switch (not shown) that controls the electronic sound-generating module and a charging port (not shown) connected to the rechargeable battery. Optionally, child carrier 100 may further include a primary battery (not shown) instead of a rechargeable battery, or may include both a primary battery and a rechargeable battery. Lighting device 140 and electronic sound-generating module may be electrically connected to the primary battery and / or the rechargeable battery to add lighting and sound functions to child carrier 100, thereby enhancing the functionality and entertainment of child carrier 100.

[0124] Additionally, referring to FIG. 21 , in at least one embodiment according to the present disclosure, the child carrier 100 may further include a USB interface 130. The USB interface 130 may be electrically connected to a primary battery and / or a rechargeable battery. As an example, the USB interface 130 may be disposed on the bottom side of the frame body 10. Additionally, as shown in FIG. 21 , the USB interface 130 may include an openable sealing cover to prevent contamination of the USB interface 130 by dust, rainwater, etc.

[0125] As shown in FIGS. 24-25 , in at least one embodiment according to the present disclosure, the child carrier 100 may further include at least one power generating assembly 500 mounted within at least one of the front wheel 31 and the rear wheel 41. The power generating assembly 500 generates power through the rotation of the wheel. The power may be converted to direct current by a rectifier 530 (see FIGS. 24 and 25 ) to power at least one of the above-mentioned light-emitting device 140, the electronic sound generating module, the rechargeable battery, and the USB interface 130. The power generating assembly 500 and the child carrier 100 having the power generating assembly according to at least one embodiment of the present disclosure are described in detail below.

[0126] In at least one embodiment according to the present disclosure, the child carrier 100 further includes at least one power generating assembly 500 mounted within at least one of the front wheel 31 and the rear wheel 41. The power generating assembly 500 may have a rectifier 530, and transmits power generated by the power generating assembly 500 to at least one of the above-mentioned light device 140, electronic sound generating module, rechargeable battery, and USB interface 130 via the rectifier 530. When there are multiple power generating assemblies 500, two or more power generating assemblies 500 may share one rectifier or may have their own rectifier. The rectifier 530 rectifies and filters the AC current generated by the power generating assembly 500 to form a stable DC current that is supplied to loads such as the light device 140, electronic sound generating module, and USB interface 130. In addition to converting AC to DC, rectifier 530 may also be configured to route power generated by power generation assembly 500 to a rechargeable battery and provide a stable charging voltage for the rechargeable battery, thereby acting as a charger. Rectifier 530 may assist in detecting wireless signals, etc. For example, rectifier 530 may assist in receiving remote control signals to control the light-emitting and sound-generating modules of child carrier 100.

[0127] 24 and 25 , the power generation assembly 500 may be mounted within the front wheel 31 and may include a support member 510. The support member 510 is mounted on the front axle 33 of the front wheel 31 and has an extension end 511 extending from the front wheel 31 along the extension direction of the front axle 33. The extension end 511 is fixed to a lower end of the front fork 32. The power generation assembly 500 includes a generator assembly 520, a drive gear 522, and a transmission gear 512. The generator assembly 520 is mounted on the support member 510 and has an input shaft 521. In one embodiment, the generator assembly 520 may include a generator and a reducer. The generator may be a micro-generator, and the reducer is axially connected to the micro-generator. Through transmission cooperation between the drive gear 522 and the reducer, the micro-generator is driven to rotate and generate power. Specifically, the drive gear 522 is mounted on the input shaft 521, and the transfer gear 512 is mounted on the front axle 33 and is configured to rotate with the rotation of the front axle 33 to rotate the drive gear 522 and generate power.

[0128] Similarly, the power generation assembly 500 may alternatively be mounted within the rear wheel 41 and may include a support member 510. The support member 510 is mounted on the rear axle 43 of the rear wheel 41 and has an extended end 511 extending from the rear wheel 41 along the extension direction of the rear axle 43. The extended end 511 is fixed and supported by a lower end of the rear wheel stand 42. The power generation assembly 500 further includes a generator assembly 520, a drive gear 522, and a transmission gear 512. The generator assembly 520 is mounted on the support member 510 and has an input shaft 521. The drive gear 522 is mounted on the input shaft 521, and the transmission gear 512 is mounted on the rear axle 43 and configured to rotate with rotation of the rear axle 43 to rotate the drive gear 522 and generate electricity.

[0129] In this embodiment, the drive gear 522 and the transfer gear 512 are engaged with each other. The transmission ratio between the transfer gear 512 and the drive gear 522 may be 1:1. However, the present disclosure is not limited thereto. Depending on the size of the interior space of the wheel to which the power generating assembly 500 is attached and / or the specifications of the power generating assembly 500, the transmission ratio between the transfer gear 512 and the drive gear 522 may alternatively be greater than or less than 1:1.

[0130] The rectifier 530 is electrically connected to the generator assembly 520 via electric wires 501 to output direct current. The rectifier 530 may be disposed within the wheel, or within a corresponding cavity defined in the leading assembly 20, the front fork 32, or the rear wheel stand 42, to reduce vibration and facilitate transmission of power generated by the power generating assembly 500 via the rectifier 530 to at least one of the above-mentioned light-emitting device 140, the electronic sound generating module, the battery (e.g., a rechargeable battery), and the USB interface 130. In addition, the electrical-related device may alternatively be mounted within the frame body 10. For example, the electrical-related device may be supported and / or covered by the above-mentioned first connecting member 11 or other similar connecting member.

[0131] As shown in FIGS. 1-9 and 18-25, the front wheel assembly 30 may have a pedal device 34. When the power generating assembly 500 is disposed in the front wheel 31, when a child pedals the child carrier using the pedal device 34, the front axle 33 and the front wheel 31 may be driven to rotate. In this case, the generator assembly 520 may generate electricity under the drive of the transmission gear 512 and the drive gear 522. In addition, when a person caring for a child pushes the child carrier 100 by pushing the push rod 60, and the front wheel 31 rotates, the front axle 33 may also be driven to rotate such that the generator assembly 520 generates electricity.

[0132] Similarly, power can alternatively be generated in place by manually turning the pedal device 34, rotating the wheels in which the power-generating assemblies are mounted, or pushing the child carrier 100. If necessary, the power-generating assembly 500 can also include a corresponding control switch or clutch to stop unnecessary power generation or supply. In addition, the generator assembly 520 is mounted within the front and / or rear wheels, so that the addition of the power-generating assembly 500 does not affect the overall appearance of the child carrier 100, and most of the sound generated when the power-generating assembly 500 is operating is blocked or absorbed, resulting in reduced noise pollution.

[0133] The child carrier according to the embodiment of the present disclosure has a simple towing structure and enhances the control flexibility of the leading assembly 20. When the unlocking assembly is in the unlocked position, the leading assembly 20 and the front wheel assembly 30 can rotate separately, which helps the user save the effort of pushing the child carrier and improves the child's experience of operating the child carrier.

[0134] In addition, according to the child carrier provided in the embodiments of the present disclosure, the wheels are equipped with power generating assemblies, so that whether the child carrier is pushed by a user or a child pedals the child carrier, or in some cases, the wheels are rotated by pedaling or manually turning on the spot, self-powered power generation can be achieved by the rotation of the wheels, and the generated power can be used for lighting, battery charging, USB charging, electronic sound generation, etc., thereby extending the functionality of the child carrier. Because the main noise-generating device of the power generating assembly (i.e., the generator assembly) is mounted in the wheel, the child carrier including the power generating assembly according to the present disclosure has low power-generating noise and is more suitable for use by children.

[0135] 26 to 29 schematically show a child carrier 100 according to a second embodiment of the present disclosure. The child carrier 100 in this embodiment includes a frame body 10, a leading assembly 20, a front wheel assembly 30, a rear wheel assembly 40, a seat 50, a push rod 60, and a power generating assembly 500. The frame body 10, the leading assembly 20, the rear wheel assembly 40, the seat 50, and the push rod 60 in this embodiment all have the same structures and connection relationships as the frame body 10, the leading assembly 20, the rear wheel assembly 40, the seat 50, and the push rod 60 in the first embodiment, with the main difference being the specific structures of the front wheel assembly 30 and the power generating assembly 500.

[0136] As shown in FIGS. 26 and 27 , the front wheel assembly 30 includes a front wheel 31 and a front fork 32. In an embodiment according to the present disclosure, the front fork 32 is coaxially connected to the leading assembly 20 and is configured to be selectively fixedly or rotatably connected to the leading assembly 20. The leading assembly 20 and the front wheel assembly 30 are rotatably connected to a first connecting member 11 that is fixedly connected to the frame main body 10. Thus, the leading assembly 20 and the front wheel assembly 30 are connected to the frame main body 10 via the first connecting member 11 so as to rotate synchronously or separately. When the front wheel assembly 30 is pushed or pedaled forward or backward, the first connecting member 11 drives the frame main body 10 and the rear wheel assembly 40 to move forward or backward together.

[0137] As shown in FIGS. 27 to 30 , the front fork 32 further includes a pair of fork arms 321 and a rotating base 322 connected between the pair of fork arms 321. The pair of fork arms 321, i.e., the first fork arm 3211 and the second fork arm 3212, are configured to be coupled to two opposite sides of the front wheel 31, respectively. The rotating base 322 is located between the pair of fork arms 321 and is configured to be selectively rotatably connected or fixedly connected to the leading assembly 20. The pair of fork arms 321 may be formed separately or integrally.

[0138] 29 and 33 , in one embodiment, an internal space 320 is formed in each of the first fork arm 3211 and the second fork arm 3212. For example, the first fork arm 3211 includes a first fork arm body and a first fork arm housing, forming the internal space 320 between the first fork arm body and the first fork arm housing. The second fork arm 3212 includes a second fork arm body and a second fork arm housing, forming the internal space 320 between the second fork arm body and the second fork arm housing. The first fork arm body and the second fork arm body may be formed separately and connected to each other, or may be integrally formed as the fork arm body 3210. Similarly, the first and second fork arm housings may also be formed separately and connected to the fork arm body 3210, or may be connected to the first and second fork arm bodies, respectively, to form the first fork arm 3211 and the second fork arm 3212. Alternatively, the first and second fork arm housings may be integrally formed and connected to the fork arm body 3210 to simultaneously form the first fork arm 3211 and the second fork arm 3212.

[0139] 33, the rotating base 322 is disposed between the pair of fork arms 321, and an internal space 320 is further formed at the bottom of the rotating base 322. The internal space 320 may or may not be in communication with the internal spaces 320 formed in the first fork arm 3211 and the second fork arm 3212.

[0140] 29 and 30, the internal spaces 320 formed within the first fork arm 3211 and the second fork arm 3212 are configured to accommodate the first operating member 540 and the second operating member 550, respectively, which will be described in detail below. The first fork arm housing and the second fork arm housing, configured to form the aforementioned internal spaces 320, each include a first opening 3216 and a second opening 3215, thereby exposing the first operating button 541 of the first operating member 540 and the second operating button 551 of the second operating member 550 for user operation.

[0141] 29 and 30 , the first operating member 540 includes a first body portion 542 that extends vertically, and a lower end portion 543 of the first body portion 542 that is configured to clamp the support member 510. The support member 510, which is configured to support the generator assembly 520, will be described in more detail below. The first operating button 541 is disposed on the first body portion 542 and is exposed through the first opening 3216. In this embodiment, the first operating button 541 may protrude from the outer surface of the first fork arm 3211. Similarly, as shown in FIG. 30 , the second operating member 550 includes a second body portion 552 that extends vertically, and a lower end portion 553 of the second body portion 552 that is configured to contact and push the second drive component 570. The second drive component 570 will be described in more detail below. The second operating button 551 is disposed on the second body portion 552 and is exposed through the second opening 3215. In this embodiment, the second operating button 551 protrudes from the outer surface of the second fork arm 3212 through the second opening 3215.

[0142] The first fork arm 3211 and the second fork arm 3212 face each other and include a first axle hole 3217 and a second axle hole 3218 used for inserting the front axle 33. More specifically, the lower end of the first fork arm body and the lower end of the second fork arm body may include a first clamp groove 330 and a second clamp groove 340, respectively. Additionally, the first fork arm housing may include a first upper housing coupled to a portion of the first fork arm body above the first axle hole 3217, and a first lower housing 3213 coupled to a portion of the first fork arm body below the first axle hole 3217. Similarly, the second fork arm housing may include a second upper housing coupled to an upper portion of the second axle hole 3218 in the second fork arm body, and a second lower housing 3214 coupled to a lower portion of the second axle hole 3218 in the second fork arm body.

[0143] When the first lower housing 3213 and the second lower housing 3214 are not assembled, the two sides of the front axle 33 can be coupled to the first axle hole 3217 and the second axle hole 3218, respectively, or can be disassembled from the first axle hole 3217 and the second axle hole 3218 via the first clamping groove 330 and the second clamping groove 340. In at least one embodiment according to the present disclosure, the two sides of the front axle 33 can be machined to have opposing flat surfaces, whereby the minimum radial dimension of the flat surfaces can be smaller or slightly smaller than the width of the first clamping groove 330 and the second clamping groove 340. After installing the front axle 33 in the first axle hole 3217 and the second axle hole 3218, installation of the front fork 32 and front wheel 31 can be completed by attaching the first lower housing 3213 and the second lower housing 3214 to the first fork arm body and the second fork arm body, respectively.

[0144] Additionally, in at least one embodiment according to the present disclosure, the front wheel assembly 30 includes pedals attached to the outside of the first and second fork arms 3211 and 3212, respectively, and firmly connected to the two ends of the front axle 33. device When a child sitting on the child carrier 100 pushes the pair of pedal devices 34 with both feet, the front axle 33 and the pedal devices 34 rotate synchronously.

[0145] In accordance with at least one embodiment of the present disclosure, the generator assembly 520 of the power generation assembly 500 is mounted within the front wheel assembly 30. However, in other embodiments, the generator assembly 520 of the power generation assembly 500 may alternatively be mounted within the rear wheel assembly 40. With reference to Figures 29-32, the front wheel assembly 30 having the generator assembly 520 will now be described in detail.

[0146] As shown in FIGS. 29 and 30 , the front wheel 31 has a rim 310 and a hub mounted on the front axle 33 to support the rim 310. In this embodiment, the hubs may include a first hub 311 and a second hub 312 connected to each other. The generator assembly 520 and its support member 510 are mounted within the front wheel 31 and are rotatably supported by the front axle 33 and configured to selectively receive torque from the front axle 33. The support member 510 fixedly supports the generator assembly 520 and is configured to be fixedly supported relative to the first fork arm 3211 and rotatably supported relative to the front axle 33. In this disclosure, "rotatably supported" means that the supported member rotates asynchronously with the support member or cannot be driven to rotate by the support member while the support member rotates.

[0147] 29 , the support member 510 has a support body portion 513 and a generator mounting portion 514 extending radially from the support body portion 513. The generator assembly 520 is mounted on the generator mounting portion 514. The support body portion 513 is mounted on the front axle 33 and abuts the inside of the first hub 311. The support member 510 further includes an extended end portion 511 connected to the support body portion 513. The extended end portion 511 of the support member 510 can extend from the first hub 311 and can be clamped by a first operating member 540 to prevent rotation of the support member 510. The extended end portion 511 is machined to have a flat surface or a pair of flat surfaces that are parallel to each other, allowing it to be clamped by a lower end portion 543 of the first operating member 540 mounted within the first fork arm 3211.

[0148] 32, more specifically, a limiting rib 519 protruding in the radial direction is formed on the outer peripheral surface of the support body portion 513. The limiting rib 519 abuts the inside of the first hub 311. Therefore, the support member 510 is fixed relatively to the first fork arm 3211, and the generator assembly 520 can be fixed to the front fork 32 and will not rotate with the rotation of the front wheel 31 and front axle 33. To achieve the above-mentioned "rotatably supported," the front axle 33 and the support member 510 are configured to have a loose fit, and the first hub 311 and the support member 510 are also configured to have a loose fit.

[0149] 29-32 , the front wheel assembly 30 further includes a transfer gear 512 slidably mounted on the front axle 33 and rotating synchronously therewith. Correspondingly, the generator assembly 520 further includes an input shaft 521 and a drive gear 522 selectively engaged with the transfer gear 512. The drive gear 522 may be mounted on the input shaft 521 and configured to selectively receive torque from the transfer gear 512 and the front axle 33. In at least one embodiment of the present disclosure, the generator assembly 520 includes a generator and a reducer. The generator may be a micro-generator, and the reducer is axially connected to the micro-generator. Through the transmission cooperation between the drive gear 522 and the reducer, the micro-generator is driven to rotate and generate power.

[0150] To this end, as shown in FIGS. 29 to 32 , in at least one embodiment according to the present disclosure, the front wheel assembly 30 further includes a first drive component 560 and the aforementioned first operating member 540 that is directly or indirectly connected to or in contact with the first drive component 560. The first drive component 560 is slidably disposed on the front axle 33 and rotates synchronously therewith. In at least one embodiment according to the present disclosure, one portion of the first drive component 560 is disposed between the support member 510 and the transfer gear 512, and the other portion of the first drive component 560 is formed as a rod-shaped portion 562 that can pass through the support member 510 and contact the first operating member 540. The first drive component 560 is configured to be disengaged from the drive gear 522 by driving and sliding the transfer gear 512. More specifically, the extension end 511 of the support member 510 has a pair of parallel flat surfaces or is machined to have a flat surface. The rod-shaped portion 562 passes through the support body portion 513 of the support member 510 and extends along the flat surface of the extension end 511, with the end of the rod-shaped portion 562 formed as a slope. The lower end 543 of the vertically disposed first operating member 540 is also formed as a slope. When the first operating member 540 slides downward relative to the first fork arm 3211 by operating the first operating button 541 on the first operating member 540, the resistance between the slopes pushes the first drive component 560, pushing the transfer gear 512 and disengaging it from the drive gear 522. In this way, the generator assembly 520 no longer receives torque from the rotating front axle 33, thereby disabling the power generation function of the generator assembly 520.

[0151] 33-38, the front wheel assembly 30 further includes a first elastic member 580 disposed between the second hub 312 and the first drive component 560. FIGS. 33-35 show that the first operating member 540 is in a first position, in which the first elastic member 580 is in a normal state and the first drive component 560 allows the transfer gear 512 to transfer torque generated by rotation of the front axle 33 to the generator assembly 520. FIGS. 36 and 37 show that the first operating member 540 is in a second position, in which the first elastic member 580 is in a compressed state and the first drive component 560 does not engage the transfer gear 512 with the drive gear 522, and therefore cannot transfer torque generated by rotation of the front axle 33 to the generator assembly 520.

[0152] When the first operating member 540 moves from the second position to the first position, the compressed first elastic member 580 drives the first drive component 560 to move toward the first hub 311, thereby causing the transfer gear 512 to re-engage with the drive gear 522. As the front axle 33 rotates, the transfer gear 512 transfers torque generated by the rotation of the front axle 33 to the generator assembly 520 for power generation. The transmission ratio between the transfer gear 512 and the drive gear 522 may be 1:1. However, the present disclosure is not limited thereto. Depending on the size of the internal space of the wheel to which the power generation assembly 500 is attached and / or the specifications of the power generation assembly 500, the transmission ratio between the transfer gear 512 and the drive gear 522 may be greater than or less than 1:1.

[0153] In the above embodiment, the clutch function of the generator is introduced by using the first drive component 560 having the rod-shaped portion 562 as an example. However, those skilled in the art should understand that the structure of the first drive component 560 is not limited thereto and may have other suitable structures. For example, the rod-shaped portion 562 may be formed separately from the first drive component 560. For example, the terminal end of the rod-shaped portion 562 may be formed as a curved surface. Correspondingly, the lower end 543 of the first operating member 540 may also be formed as a curved surface. That is, at least one of the terminal end of the rod-shaped portion 562 and the lower end 543 of the first operating member 540 is formed as an inclined slope or a curved surface, so that the lower end 543 of the first operating member 540 can push the first drive component 560 to push the transmission gear 512 along the front axle 33 and disengage it from the drive gear 522.

[0154] Additionally, although the first operating member 540 and the first drive component 560 are in direct contact with each other in the above-described embodiments, the present disclosure is not limited thereto. For example, the first operating member 540 can indirectly control the sliding of the first drive component 560 on the front axle 33 via a traction cable, a spring member, or the like. Additionally, although the torque generated by the front axle 33 is selectively transmitted to the generator assembly 520 by changing the axial position of the transfer gear 512 via the first drive component 560 in the above-described embodiments of the present disclosure, the present disclosure is not limited thereto. For example, a drive component can be disposed between the generator assembly 520 and the support member 510 to change the axial and / or radial position of the drive gear 522 relative to the front axle 33, thereby selectively transmitting the torque generated by the front axle 33 to the generator assembly 520. That is, the generator assembly 520 may be slidably mounted on the generator mounting portion 514 and may be configured to be movable axially and / or radially relative to the front axle 33 to engage or disengage the drive gear 522 with the transfer gear 512. In the above description, the first resilient member 580 is described as being disposed between the second hub 312 and the first drive component 560, but the present disclosure is not limited thereto.

[0155] For example, as shown in FIGS. 33 to 38 , the front wheel assembly 30 may further include a first axle sleeve 596 that rotatably supports the second hub 312 and is fixed to the front axle 33 so as to abut the inside of the second hub 312 in the axial direction. A first elastic member 580 may be disposed between the transfer gear 512 and the first axle sleeve 596 to apply an elastic force to the transfer gear 512. The second hub 312 is rotatably supported by the first axle sleeve 596, which means that the second hub 312 cannot receive torque from the front axle 33 via the first axle sleeve 596.

[0156] A front wheel drive clutch mechanism in accordance with at least one embodiment of the present disclosure is described in more detail below with reference to Figures 28-38.

[0157] As shown in FIGS. 29-32 , the second hub 312 can be configured to selectively receive torque from the front axle 33 via the second operating member 550 and the second drive component 570 and transmit torque generated when the front wheel 31 rotates to the front axle 33. In at least one embodiment according to the present disclosure, as shown in FIGS. 33-38 , the second drive component 570 is slidably disposed on the front axle 33 and rotates synchronously with the front axle 33. The lower end 553 of the second operating member 550 remains in contact with the second drive component 570 and moves between a third position and a fourth position to allow the second drive component 570 to slide along the front axle 33. When the second operating member 550 is in the third position, as shown in FIGS. 31 and 33-37 , the second drive component 570 engages with the second hub 312 to transmit torque between the front wheel 31 and the front axle 33. When the second operating member 550 is in the fourth position, as shown in FIG. 38, the second drive component 570 is disengaged from the second hub 312, and torque is no longer transmitted between the front wheel 31 (i.e., the second hub 312) and the front axle 33.

[0158] By selectively transmitting torque between the front wheel 31 and the front axle 33, a front-wheel drive clutch function is added to the front wheel assembly 30, enhancing the use modes and functionality of the child carrier having the front wheel assembly 30. When the second operating member 550 is in the fourth position, pushing the child carrier 100 rotates the front wheel 31 but not the front axle 33. This saves the user's pushing effort. In addition, when the child pedals the pedal device 34, torque can be applied only to the front axle 33. In this way, it is easy for the child to pedal without interfering with the user's pushing action. In addition, when the first operating member 540 is in the second position, the generator assembly 520 can generate power. Therefore, when the child pedals the pedal device 34, the drive gear 522 of the generator assembly 520 and the front axle 33 rotate synchronously to generate power.

[0159] As shown in FIGS. 30 to 33 , the second operating member 550 is vertically disposed within the second fork arm 3212 and can slide up and down relative to the second fork arm 3212. The second operating member 550 is configured to push the second drive component 570 to slide along the front axle 33 and disengage from the second hub 312. As shown in FIGS. 30 and 33 , the contact surface between the second drive component 570 and the second operating member 550 is formed as a slope. However, the present disclosure is not limited thereto, and the contact surface between the second drive component 570 and the second operating member 550 may alternatively be formed as a curved surface. Those skilled in the art will understand that the second operating member 550 can be moved from the third position to the fourth position as long as one contact surface between the second drive component 570 and the second operating member 550 is formed as a slope or curved surface. As a result, the second drive component 570 moves to a position where it is disengaged from the second hub 312 .

[0160] The particular structure of the second hub 312 and second drive component 570 in accordance with at least one embodiment of the present disclosure is described in more detail below with reference to FIGS. 31-33.

[0161] The second drive component 570 includes a frustoconical body portion 571 and a connecting hole 572 formed in the body portion 571. The body portion 571 is slidably connected to the front axle 33 through the connecting hole 572, thereby allowing the body portion 571 to rotate synchronously with the front axle 33. As shown in FIG. 32 , a hole wall of the connecting hole 572 includes a pair of opposing flat surfaces such that the second drive component 570 is slidable relative to the front axle 33. The second drive component 570 further includes a plurality of engagement portions 573 extending radially outward from the body portion 571.

[0162] The second hub 312 has a central recessed portion 3125 and a second central hole 3120 located in the center of the second hub 312. The second central hole 3120 can be inserted into and rotatably support a second axle sleeve 595 of the second hub 312, and the second axle sleeve 595 can be slidably connected to the front axle 33 or fixedly connected to rotate synchronously therewith. For this purpose, the second axle sleeve 595 is clearance-fitted into the second central hole 3120 of the second hub 312, whereby the second axle sleeve 595 rotatably supports the second hub 312.

[0163] In addition, the second axle sleeve 595 is disposed in the central recessed portion 3125 of the second hub 312 and is attached near one side of the second drive component 570. That is, the second axle sleeve 595 is configured to rotatably support the second hub 312 without transmitting torque from the second hub 312 to the front axle 33 or from the front axle 33 to the second hub. In addition, the second axle sleeve 595 is attached on the front axle 33 so as to contact the outer side of the second hub 312 in the axial direction, and faces the first axle sleeve 596. More specifically, the first axle sleeve 596 and the second axle sleeve 595 are attached so as to contact two sides of the central recessed portion 3125, respectively. The second axle sleeve 595 may slide relative to the front axle 33 or may be fixed to the front axle 33 by an interference fit. The second elastic member 590 is axially disposed between the second axle sleeve 595 and the second drive component 570, thereby providing an elastic force for the second drive component 570.

[0164] A plurality of engagement portions 3128 are formed on a circumferential sidewall of the central recessed portion 3125, and slots 3127 are formed between adjacent engagement portions 3128. When the second drive component 570 engages with the second hub 312, the plurality of engagement portions 573 are disposed between corresponding slots 3127, so that the second drive component 570 can transmit torque between the front axle 33 and the second hub 312, thereby transmitting torque from the front axle 33 to the front wheels 31 or transmitting torque from the front wheels 31 to the front axle 33.

[0165] 32 , the plurality of engagement portions 573 are axially spaced apart from the bottom side of the central recessed portion 3125 (i.e., the side closer to the second drive component 570), thereby forming an interval space 3129 for accommodating the second drive component 570. When the second operating button 551 is operated to move the second operating member 550 downward from the third position to the fourth position, the lower end portion 553 of the second operating member 550 pushes the second drive component 570 and moves it toward the first hub 311 into the interval space 3129, as shown in FIG. 38 , thereby disengaging the second drive component 570 from the second hub 312. In this case, the second drive component 570 can rotate synchronously with the front axle 33 but does not transmit torque between the second hub 312 (i.e., the front wheel 31) and the front axle 33.

[0166] When the second operating button 551 is operated to move the second operating member 550 upward from the fourth position to the third position, the elastic force of the second elastic member 590 pushes the second drive component 570, causing it to move toward the outside of the second hub 312 and again engage with the second hub 312. In this case, the second drive component 570 rotates in synchronization with the front axle 33, and at the same time, torque can be transmitted between the second hub 312 (i.e., the front wheel 31) and the front axle 33.

[0167] It is apparent from the above description that by operating the second operating member 550 to change the axial position of the second drive component 570, the second drive component 570 can selectively transmit torque between the front axle 33 and the front wheel 31. Thus, the front wheel assembly 30 realizes a front wheel drive clutch function via the second operating member 550 and the second drive component 570, thereby enhancing the use modes and functionality of the child carrier 100.

[0168] In the above embodiment, the second hub 312 and the second drive component 570 engage in the radial direction via multiple engagement portions, but the present disclosure is not limited thereto. For example, the number and protruding directions of the engagement portions are not limited to the number and directions shown in the drawings of the present disclosure. That is, the second drive component 570 may have at least one engagement portion protruding in the axial and / or radial directions, and the second hub 312 may have at least one slot that engages with the at least one engagement portion. In some other embodiments, the second drive component 570 includes a frustoconical body portion 571 and at least one slot formed on the body portion and recessed in the axial and / or radial directions, and the second hub 312 may have at least one engagement portion that engages with the at least one slot.

[0169] As can be seen from the above description, the first operating member 540 and the first drive component 560 resist each other, and by moving the first operating member 540 between the first position and the second position and by the elastic force of the first elastic member 580, the first drive component 560 is moved along the front axle 33, thereby selectively transmitting torque generated by the front axle 33 to the generator assembly 520. To stably maintain the first operating member 540 at the first position or the second position, as shown in FIG. 34 , the first operating member 540 further includes a first positioning assembly movably disposed between the first body portion 542 and the first fork arm body to position the first operating member 540. In this embodiment, the first positioning assembly may include a first ball 546 and a first spring 545, and the first ball 546 and the first spring 545 are disposed within the first body portion 542. 33 , a corresponding first locating recess 3201 and a corresponding second locating recess 3202 are provided on the first fork arm body to receive a portion of the first ball 546. Alternatively, the first ball 546 and the first spring 545 may be disposed within the first fork arm body, and a corresponding first locating recess 3201 and a corresponding second locating recess 3202 are provided on the first body portion 542 to receive a portion of the first ball 546.

[0170] 33 , when the first ball 546 is received in the first positioning recess 3201, the first operating member 540 is located at a first position. When the first ball 546 is received in the second positioning recess 3202, the first operating member 540 is located at a second position. Depending on the specific positions of the first positioning recess 3201 and the second positioning recess 3202, when the first ball 546 is received in the first positioning recess 3201, the first operating member 540 may be located at the second position, and when the first ball 546 is received in the second positioning recess 3202, the first operating member 540 may be located at the first position.

[0171] Similarly, to stably maintain the second operating member 550 at the third or fourth position, as shown in FIG. 34 , the second operating member 550 further includes a second positioning assembly movably disposed between the second body portion 552 and the second fork arm body for positioning the second operating member 550. As shown in FIG. 33 , the second positioning assembly may include a second ball 556 and a second spring 555, where the second ball 556 and the second spring 555 are disposed within the second body portion 552. The second fork arm body includes a corresponding third positioning recess 3203 and a corresponding fourth positioning recess 3204 for accommodating a portion of the second ball 556. Alternatively, the second ball 556 and the second spring 555 may be disposed within the second fork arm body, with a corresponding third positioning recess 3203 and a corresponding fourth positioning recess 3204 being provided on the second body portion 552 to receive a portion of the second ball 556.

[0172] 33 , when the second ball 556 is received in the third positioning indentation 3203, the second operating member 550 is located in the third position. When the second ball 556 is received in the fourth positioning indentation 3204, the second operating member 550 is located in the fourth position. Depending on the specific positions of the third positioning indentation 3203 and the fourth positioning indentation 3204, the second operating member 550 may be located in the fourth position when the second ball 556 is received in the third positioning indentation 3203. When the second ball 556 is received in the fourth positioning indentation 3204, the second operating member 550 is located in the third position.

[0173] The detailed configuration of the power generating assembly 500 will be described below with reference to FIGS. 29-30, 33, 34, and 36. FIG.

[0174] In addition to the generator assembly described above, similar to the first embodiment, the power generation assembly 500 further includes an electric wire 501 and a rectifier 530. In an embodiment according to the present disclosure, as shown in Figures 30 and 34, the rectifier 530 may be mounted within the interior space 320, and more specifically, may be located at the bottom of the rotating base 322 of the front fork 32 in the interior space 320.

[0175] In addition, the support member 510 includes an axially extending threaded hole 518 (see FIG. 36 ). Referring to FIGS. 29 and 30 together, the electric wire 501 extending from the generator assembly 520 can extend through the threaded hole 518 into the first fork arm 3211 of the front fork 32. To prevent interference between the electric wire 501 and the first operating member 540, the electric wire 501 can be extended downward or upward to avoid the front axle 33, the first operating member 540, and other moving components extending to the rectifier 530. Because the support member 510 is fixed relative to the front fork 32, it is possible for the electric wire 501 to not cause interference when the front wheel 31 and / or the front axle rotate.

[0176] Similar to the first embodiment, the child carrier 100 may further include at least one of a rechargeable battery, a light-emitting module, a sound-generating module (not shown), and a USB interface (not shown), which are electrically connected to the power generating assembly 500. The power generated by the generator assembly may be stored in the rechargeable battery after being rectified by the rectifier 530, or may be used for lighting, music playback, and external power supply via the USB interface. The light-emitting module may be used as a lighting lamp on the child carrier 100 to provide light for children to play at night. For example, the light-emitting module may include a light-emitting device and a switch for the light-emitting device. The light-emitting device and the switch for the light-emitting device may be attached to the front and rear sides of the lead assembly, respectively. The sound-generating module may include a sound-generating device and a switch for the sound-generating device. The light-emitting module and the sound-generating module (not shown) may be electrically connected to the rechargeable battery (not shown). Optionally, the child carrier 100 may additionally include a primary battery (not shown), or alternatively, may include a primary battery without a rechargeable battery. The light-emitting module and sound-generating module may be electrically connected to the primary battery and / or the rechargeable battery, and the USB interface may also be electrically connected to the primary battery and / or the rechargeable battery. The light-emitting module and sound-generating module may add lighting and sound functions to the child carrier 100, thereby enhancing the functionality and entertainment value of the child carrier 100. The USB interface provides a power emergency solution for the child carrier 100. For example, the USB interface sends power generated by the primary battery, the rechargeable battery, or the power-generating assembly to a device that needs to be charged, such as a user's portable electronic product, such as a mobile phone, a game console, or a PAD. In addition, when the child carrier 100 includes a sound-generating module, the USB interface may also provide a data transmission function.

[0177] Additionally, in at least one embodiment according to the present disclosure, a generator assembly 520 may be disposed within at least one of the front wheel 31 and the rear wheel 41 of the child carrier 100. The generator assembly generates electric power through the rotation of the axles of the front wheel 31 and the rear wheel 41 (i.e., the front axle 33 and the rear axle 43). The electric power may be converted to direct current via one or more rectifiers 530 to power at least one of the light-emitting module, the sound-generating module, the rechargeable battery, and the USB interface, respectively or together. As an example, the USB interface may be disposed on the bottom side of the frame body 10. Additionally, the USB interface may include an openable sealing cover to prevent contamination of the USB interface by dust, rainwater, etc.

[0178] As mentioned above, when there are multiple power generation assemblies 500, two or more power generation assemblies 500 may share a rectifier or have their own rectifiers to rectify and filter the AC current generated by the power generation assemblies 500 to form a stable DC current supplied to loads such as the light generation module, sound generation module, and USB interface. Additionally, when there is no electrical load, the rectifier 530 may route the power generated by the power generation assemblies 500 to a rechargeable battery and provide a stable charging voltage for the rechargeable battery, thereby acting as a charger.

[0179] In the above embodiment, the power generating assembly 500 is mounted within the front wheel assembly 30. However, the present disclosure is not limited thereto. That is, the generator assembly 520 and the electrical wiring 501 of the power generating assembly 500 may alternatively be mounted within the rear wheel 41. That is, in addition to the pedal assembly, the rear wheel assembly 40 may have the same structure and internal configuration as the front wheel assembly 30.

[0180] In the above description, the rectifier 530 is electrically connected to the generator assembly 520 via the electric wire 501 and configured to output direct current. The rectifier 530 may be disposed within a corresponding wheel, or within a corresponding cavity within the leading assembly 20, the front fork 32, or a cavity defined within the rear wheel stand 42, to reduce vibrations and facilitate transmission of power generated by the power generating assembly 500 via the rectifier 530 to at least one of the above-mentioned light-emitting module, the sound-generating module, the rechargeable battery, and the USB interface. In addition to the generator assembly 520, an electrical-related device may alternatively be mounted within the frame body 10. For example, the electrical-related device may be supported and / or covered by the above-mentioned first connecting member 11 or other similar connecting member.

[0181] According to the child carrier disclosed in the present disclosure, the front wheel assembly 30 may have a pedal device 34. A power generating assembly 500 is disposed in the front wheel 31, and when the first operating member 540 is in the first position and the second operating member 550 is in the third position, and a child uses the pedal device 34 to pedal the child carrier or a user pushes the child carrier 100, the front axle 33 may be driven to rotate together. In this case, the generator assembly 520 may generate electricity under the drive of the transmission gear 512 and the drive gear 522.

[0182] When the first operating member 540 is in the first position and the second operating member 550 is in the fourth position, power can alternatively be generated by manually pivoting the pedal device 34 in place or by pedaling the child carrier in place to rotate the axle of the wheel having the power generating assembly mounted therein. In this case, pushing the child carrier 100 cannot drive the axle to rotate and therefore cannot generate power.

[0183] When the first operating member 540 is in the second position and the second operating member 550 is in the third position, the power-generating function is disabled and the child carrier 100 can simply be pushed or can simply be pedaled by a child. When the first operating member 540 is in the second position and the second operating member 550 is in the fourth position, the power-generating function is disabled and pushing the child carrier and pedaling the child carrier can no longer interfere with each other.

[0184] In various embodiments of the present disclosure, because the generator assembly 520 is mounted within the front and / or rear wheels, the addition of the power generating assembly 500 may not affect the overall appearance of the child carrier 100, and most of the sound generated when the power generating assembly 500 is operating is blocked or absorbed, resulting in reduced noise pollution.

[0185] In addition, according to the child carrier provided in the present disclosure, since the wheels are equipped with power generating assemblies, whether the child carrier is pushed by a user or a child pedals the child carrier, or in some cases, the wheels are rotated by pedaling or manually turning on the spot, self-driving power generation can be achieved by the rotation of the wheel axles, and the generated power can be used for lighting, battery charging, USB charging, electronic sound generation, etc., thereby extending the functionality of the child carrier. Because the main noise-generating device of the power generating assembly (i.e., the generator assembly) is mounted in the wheel, the child carrier with the power generating assembly according to the present disclosure has low power-generating noise and is more suitable for use by children.

[0186] According to at least some embodiments of the present disclosure, the child carrier includes a wheel assembly having a generator clutch function that allows the child carrier to switch between simple pedaling function and pedal-power generating function, or between simple push-and-pull function and push-and-power generating function, thereby meeting multiple functional requirements for the child carrier.

[0187] According to at least some embodiments of the present disclosure, the child carrier includes a wheel assembly having a wheel drive clutch feature that allows only the front and / or rear wheels to rotate while pushing the child carrier without transmitting torque between the wheels and the wheel axles, thus allowing a user to push the child carrier with less effort, while at the same time preventing the pushing action from interfering with a child's ability to pedal the child carrier.

[0188] It should be noted that, according to at least some embodiments of the present disclosure, the child carrier may alternatively include only wheel assemblies with generator clutch functionality, or only wheel assemblies with wheel drive clutch functionality.

[0189] According to at least some embodiments of the present disclosure, the child carrier includes a wheel assembly having both a generator clutch function and a wheel drive clutch function, which can enable various operating modes such as power generation by pedaling on the spot, power generation by pedaling, pushing, simply pushing, simply pedaling, power generation by pushing and pedaling in parallel, power generation by pedaling while pushing, and power generation by manually pivoting the pedal assembly on the spot.

[0190] 39 to 60 schematically show a child carrier 100 according to a third embodiment of the present disclosure, which may be, for example, a child's tricycle, a child's bicycle, etc. The child carrier allows the child's legs to rest more fully, providing a better user experience.

[0191] 39 to 41, the child carrier 100 in this embodiment includes a frame body 10, a leading assembly 20, a front wheel assembly 30, a rear wheel assembly 40, a seat 50, a push rod 60, and a footrest device 600. The frame body 10, the leading assembly 20, the rear wheel assembly 40, the seat 50, and the push rod 60 in this embodiment all have the same structures and connection relationships as the frame body 10, the leading assembly 20, the rear wheel assembly 40, the seat 50, and the push rod 60 in the first embodiment, with the main difference being the specific structures of the front wheel assembly 30 and the footrest device 600.

[0192] As shown in FIGS. 39 to 41 , the footrest device 600 is connected to the underside of the frame main body 10 and is located between the front wheel assembly 30 and the seat 50. The footrest device 600 has an in-use state (shown in FIG. 39 ) and an out-of-use state (shown in FIG. 40 ) relative to the frame main body 10. While the child carrier is traveling, the footrest device 600 can be maintained in the in-use state relative to the frame main body 10. In this case, the footrest device 600 can be configured to hold a child's feet, thereby allowing the child to rest their feet on the footrest device 600 and not easily get tired due to their feet being in the air or pedaling for a long period of time. In addition, in this embodiment, the pedal device 34 is configured to drive the front wheel assembly 30. Therefore, the front wheel assembly 30 can be rotated by stepping on the pedal device 34, thereby moving the child carrier forward as a whole.

[0193] Specifically, the footrest device 600 may be in a variety of forms. For example, in this embodiment, as shown in Figures 41 and 42, the footrest device 600 includes a footrest assembly 630, a support member 610, and a connecting member 620. When the footrest device 600 is in an in-use state, the support member 610 is in a first rotated position, and the footrest assembly 630 is in an unfolded state. When the footrest device 600 is in an out-of-use state, the support member 610 is in a second rotated position, and the footrest assembly 630 is in a folded state.

[0194] In this embodiment, two footrest assemblies 630 are provided, namely, a first footrest 631 and a second footrest 632. The first footrest 631 and the second footrest 632 are pivotally connected to one end of a support member 610 via a first pivot shaft 641 and a second pivot shaft 642, respectively, and the other end of the support member 610 is pivotally connected to a connecting member 620 via a rotating shaft 643, and one end of the connecting member 620 remote from the support member 610 is fixed to the frame body 10.

[0195] 43 to 45, the support member 610 includes a support member 616, and the support member 616 has a roughly rectangular parallelepiped structure. The rectangular parallelepiped structure has a first end face 611 and a second end face 612 located at two ends. face 612. The first end surface 611 has two first connecting portions 613 and two second connecting portions 614 in a convex shape. The first footrest 631 is pivotally connected to the two first connecting portions 613 via a first pivot shaft 641, and the second footrest 632 is pivotally connected to the two second connecting portions 614 via a second pivot shaft 642. Both the first footrest 631 and the second footrest 632 have an unfolded state and a folded state relative to the support member 610. When in the unfolded state, the first footrest 631 or the second footrest 632 can be configured to support a child's feet, as shown in FIG. 43. When in the folded state, the first footrest 631 or the second footrest 632 is folded near the support member 610, as shown in FIG. 44.

[0196] 43 and 44, the footrest device 600 further includes a fixing assembly 650. In this embodiment, the fixing assembly 650 is provided between the first footrest 631 and the support member 610 and between the second footrest 632 and the support member 610. The first footrest 631 (or the second footrest 632) can be fixed to the corresponding side of the support member 610 via the fixing assembly 650 when in the folded state.

[0197] Taking the fixing assembly 650 between the first footrest 631 and the support member 610 as an example, as shown in FIGS. 43, 46, and 47, the fixing assembly 650 includes a first magnetic portion 651 disposed on the first footrest 631 and a second magnetic portion 652 disposed on the support member 610. When the footrest 631 is in the folded state, the first magnetic portion 651 and the second magnetic portion 652 can be attracted to each other. In this embodiment, the first magnetic portion 651 can be a permanent magnet embedded in the first footrest 631. The second magnetic portion 652 can be integrally formed with the rotating shaft 643. Specifically, the rotating shaft 643 can be made of a ferromagnetic material such as iron, cobalt, or nickel, and two ends of the rotating shaft 643 protrude from two sides of the support member 610 to form two second magnetic portions 652. 47, when the first footrest 631 and the second footrest 632 are in the folded state, the first magnetic portions 651 of the first footrest 631 and the second footrest 632 can be attracted to and engaged with the two second magnetic portions 652, respectively, thereby fixing both the first footrest 631 and the second footrest 632 in the folded state. As shown in FIG. 46, when it is necessary to switch the first footrest 631 (or the second footrest 632) from the folded state to the unfolded state, it is only necessary to apply an external force to the first footrest 631 (or the second footrest 632) to overcome the magnetic force between the first magnetic portion 651 and the second magnetic portion 652. In this way, the rotating shaft 643 serves to pivotally connect the support member 610 and the connecting member 620, and at the same time serves to attract and fix the first footrest 631 and the second footrest 632 to each other. There is no need to additionally arrange the second magnetic portion 652, which can simplify the installation process of the footrest device 600. Of course, in other embodiments, the second magnetic portion 652 may alternatively be additionally arranged on the support member 610 and have a structure that has ferromagnetic properties or a magnetic property opposite to that of the first magnetic portion 651.

[0198] Furthermore, as shown in FIGS. 46 and 47 , a synchronization mechanism 660 is further disposed between the first footrest 631 and the second footrest 632. The synchronization mechanism 660 can realize synchronous rotation between the first footrest 631 and the second footrest 632. In this embodiment, the synchronization mechanism 660 includes a first drive member 661 and a second drive member 662. Specifically, one end of the first footrest 631 and the first drive member 661 are pivotally connected to the first connection portion 613 via a first pivot shaft 641, and both the one end of the first footrest 631 and the first drive member 661 are fixed to the first pivot shaft 641. As shown in FIG. 43 , the first pivot shaft 641 is rotatably connected to the first connection portion 613. Similarly, one end of the second footrest 632 and the second driving member 662 are also pivotally connected to the second connecting portion 614 via a second pivot shaft 642, and both the one end of the second footrest 632 and the second driving member 662 are fixed to the second pivot shaft 642. As shown in FIG. 43 , the second pivot shaft 642 is rotatably connected to the second connecting portion 614.

[0199] 46 and 47, in this embodiment, the first driving member 661 has a first wheel toothing 661a, and the second driving member 662 has a second wheel toothing 662a. The first wheel toothing 661a and the second wheel toothing 662a are engaged with each other. In this manner, when one of the first footrest 631 and the second footrest 632 (for example, the first footrest 631) rotates relative to the support member 610 through the engagement between the first wheel toothing 661a and the second wheel toothing 662a, the other of the first footrest 631 and the second footrest 632 (for example, the second footrest 632) is driven to rotate synchronously, so that it is convenient for the user to unfold or fold the first footrest 631 and the second footrest 632 simultaneously. That is, by operating the first driving member 661 and the second driving member 662, the first footrest 631 and the second footrest 632 can be driven to rotate synchronously in opposite directions.

[0200] In this embodiment, both the first drive member 661 and the second drive member 662 are quarter gears. In this way, the rotation angle of the first footrest 631 and the second footrest 632 relative to the support member 610 can be limited, so that the first footrest 631 and the second footrest 632 always pivot between the unfolded state and the folded state. Of course, in other embodiments, the first drive member 661 and the second drive member 662 can alternatively be third gears, fifth gears, etc., as needed. This is not a limitation of the present disclosure.

[0201] Of course, in other embodiments, the first drive member 661 and the second drive member 662 may alternatively be fixed directly to one end of the first footrest 631 and one end of the second footrest 632, respectively. Thus, the first pivot shaft 641 may alternatively be rotatably connected to one end of the first footrest 631 and fixedly connected to the first connection portion 613, and the second pivot shaft 642 may alternatively be rotatably connected to one end of the second footrest 632 and fixedly connected to the second connection portion 614.

[0202] Specifically, as shown in FIGS. 43 to 45, the connecting member 620 includes a fixed portion 621 and a second pivot portion 622 connected to each other. The fixed portion 621 has a substantially U-shaped structure, and two ends of the fixed portion 621 are fixedly connected to two sides of the frame body 10 via fasteners 680 (shown in FIG. 42). The fasteners 680 may be rivets, screws, or the like. The second pivot portion 622 has a substantially cylindrical structure and is pivotally connected to the support member 610 via a rotation shaft 643.

[0203] Specifically, as shown in FIGS. 46 to 48 , two opposite sides of the first end surface 611 of the support 616 are raised to form two first pivot portions 615. Each of the two first pivot portions 615 has two pivot holes 615a. The rotation shaft 643 passes through the pivot hole 615a on one side, the second pivot portion 622, and the pivot hole 615a on the other side in sequence, thereby realizing a rotatable connection between the support member 610 and the connecting member 620. In this embodiment, the rotation shaft 643 is fixedly connected to the two first pivot portions 615, and the second pivot portion 622 is rotatable relative to the rotation shaft 643. Of course, in other embodiments, the rotation shaft 643 may alternatively be fixedly connected to the second pivot portion 622, and the two first pivot portions 615 are rotatable relative to the rotation shaft 643. In this embodiment, both the first pivot shaft 641 and the second pivot shaft 642 are perpendicular to the rotation shaft 643. Of course, in other embodiments, the angle between the first pivot shaft 641 and the rotation shaft 643 and the angle between the second pivot shaft 642 and the rotation shaft 643 may alternatively be greater than or less than 90°. In other words, the extension directions of the first pivot shaft 641 (or the second pivot shaft 642) and the rotation shaft 643 are not parallel to each other.

[0204] 46 and 48, the footrest device 600 further includes a positioning mechanism 670. The positioning mechanism 670 is disposed between the support member 610 and the connecting member 620, and is configured to fix the support member 610 relative to the connecting member 620 in the first rotational position shown in FIG. 39 or the second rotational position shown in FIG. 40. In this embodiment, two positioning mechanisms 670 are provided, each configured to achieve positioning and fixation between two sides of the second pivot portion 622 and the two first pivot portions 615, respectively, so that the support member 610 can be better positioned relative to the connecting member 620 and is not easily displaced. Of course, in other embodiments, the positioning mechanism 670 may alternatively be disposed only between one side of the second pivot portion 622 and the corresponding first pivot portion 615.

[0205] Specifically, as shown in FIGS. 46 to 48, taking one positioning mechanism 670 as an example, the positioning mechanism 670 includes a first positioning recess 671, a second positioning recess 672, a positioning protrusion 673, and a positioning reset member 674. The first positioning recess 671 and the second positioning recess 672 are spaced apart on the first side surface 615b of the first pivot portion 615, and the first positioning recess 671 and the second positioning recess 672 are spaced apart around the pivot hole 615a. The positioning protrusion 673 is movably disposed on the second pivot portion 622, and can move to protrude from the second side surface 622b of the second pivot portion 622. The first side surface 615b abuts against the second side surface 622b. As shown in FIG. 47 , the positioning protrusion 673 is movably disposed within the second pivot portion 622 and is spaced apart from the rotation shaft 643. In this embodiment, the positioning protrusion 673 can move in a direction substantially parallel to the rotation shaft 643. The positioning protrusion 673 has a first movement position and a second movement position. A plane of symmetry is present between the two first pivot portions 615, and the two first pivot portions 615 are mirror-symmetric with respect to the plane of symmetry. The positioning protrusion 673 in the first movement position is farther from the plane of symmetry than the positioning protrusion 673 in the second movement position. When the positioning protrusion 673 is in the first movement position, the positioning protrusion 673 can engage with the first positioning recess 671 or the second positioning recess 672. When the positioning protrusion 673 is in the second movement position, the positioning protrusion 673 can disengage from the first positioning recess 671 or the second positioning recess 672 and abut against the first side surface 615b. In this embodiment, the positioning protrusion 673 is a ball, and the first positioning recess 671 and the second positioning recess 672 are first and second positioning grooves that can align with the positioning protrusion 673. In this embodiment, both the first and second positioning grooves are partially spherical grooves.By utilizing the smooth rolling characteristics of the ball, the ball can move more smoothly between the first positioning groove and the second positioning groove when the support member 610 rotates around the connecting member 620. Of course, in other embodiments, the positioning protrusion 673 can alternatively be a pin-like structure, a tapered structure, or the like.

[0206] 46 to 48, the positioning reset member 674 is disposed between the positioning protrusion 673 and the support member 610, and the positioning reset member 674 urges the positioning protrusion 673 to move it toward the first movement position. Specifically, an attachment groove 622a extending in a direction parallel to the rotation shaft 643 may be disposed in the second pivot portion 622, and at least a portion of the positioning reset member 674 and the positioning protrusion 673 are disposed in the attachment groove 622a, and the two ends of the positioning reset member 674 abut against the groove bottom of the attachment groove 622a and the positioning protrusion 673. When the support member 610 is rotated to the first or second rotational position relative to the connecting member 620, the positioning reset member 674 can push at least a portion of the positioning protrusion 673 out of the mounting groove 622a through a notch in the mounting groove 622a that engages with the first positioning recess 671 or the second positioning recess 672, thereby realizing the function of fixing the support member 610 in the first or second rotational position via the connecting member 620. Optionally, the positioning reset member 674 is a spring.

[0207] Of course, in other embodiments, the positioning mechanism 670 may alternatively have other forms. For example, the first and second positioning portions may be disposed on the connecting member 620, the third positioning portion may be disposed on the support member 610, and the magnetic properties of the first and second positioning portions may be the inverse of the magnetic properties of the third positioning portion. In this way, when the support member 610 is in the first rotational position, the third positioning portion is magnetically locked to the first positioning portion, and when the support member 610 is in the second rotational position, the third positioning portion is magnetically locked to the second positioning portion. In short, the form of the positioning mechanism 670 is not limited as long as it can achieve positioning between the support member 610 and the connecting member 620. In addition, the first and second positioning portions may alternatively be disposed on the support member 610, and the third positioning portion may be disposed on the connecting member 620, or similarly for other cases.

[0208] 43, the footrest device 600 is in the unfolded state. When the footrest device 600 is not needed or when the child carrier needs to be folded as a whole, the first footrest 631 (or the second footrest 632) in the unfolded state can be rotated closer to the support member 610 to be in the folded state. In this process, the mutual engagement between the first drive member 661 and the second drive member 662 drives the end portion of the second footrest 632 (or the first footrest 631) in the unfolded state (i.e., the end portion of the second footrest 632 that is not connected to the support member 610) to be rotated closer to the support member 610 and synchronously to be in the folded state.

[0209] 47, the first footrest 631 and the second footrest 632 can be fixed to two sides of the support member 610 via a fixing assembly 650 (such as an adhesive coupling between the first magnetic portion 651 and the second magnetic portion 652). In addition, as shown in FIG. 45, the support member 610 in the first rotation position can be rotated around the rotation shaft 643 to a second rotation position, thereby switching the footrest device 600 to a folded state.

[0210] 46-48 , during rotation of the support member 610, the positioning protrusion 673, which is originally engaged with the first positioning recess 671, moves out of the first positioning recess 671 as the support member 610 rotates and moves to a first side surface 615b (shown in FIG. 48 ) of the first pivot portion 615 between the first positioning recess 671 and the second positioning recess 672. The first side surface 615b presses against the positioning protrusion 673, causing the positioning protrusion 673 to move from the first movement position to the second movement position and compress the positioning reset member 674. As the support member 610 continues to rotate to the second rotation position, the positioning protrusion 673 faces the second positioning recess 672. In this case, the positioning protrusion 673 loses the pressing force of the first side surface 615b, and moves again to the first movement position under the elastic restoring force of the positioning reset member 674, and engages with the second positioning recess 672. In this way, the folding of the footrest device 600 is completed.

[0211] Of course, during folding of the footrest device 600, the support member 610 may first rotate to the second rotation position relative to the connecting member 620, and then the first footrest 631 and the second footrest 632 may rotate to the folded state relative to the support member 610. Alternatively, depending on the user's personal requirements, the support member 610 may only rotate to the second rotation position relative to the connecting member 620, or the first footrest 631 and the second footrest 632 may only rotate to the folded state relative to the support member 610, etc. This is not limited in the present disclosure. The unfolding process of the footrest device 600 is the reverse of the folding process described above, and will not be described in detail here.

[0212] 49 and 50 , the pedal device 34 includes a pedal assembly 341, a pedal base 342, and a second disassembly mechanism 343. In this embodiment, the pedal base 342 is configured to drive the front wheel assembly 30, but the present disclosure is not limited thereto. The pedal assembly 341 is detachably connected to the pedal base 342 via the second disassembly mechanism 343. In other embodiments, the pedal device 34 may alternatively be disposed directly on the frame body 10.

[0213] Specifically, as shown in FIGS. 50 and 51 , the pedal assembly 341 includes a pedal body 3411 and a second pin shaft 3412. The pedal body 3411 can be stepped on by a child pedaling it and has a roughly rectangular parallelepiped structure. The approximate axis position of the pedal body 3411 includes a second insertion groove 3411a (see FIGS. 53 and 54 ) along its axial direction. The second pin shaft 3412 is partially inserted into the second insertion groove 3411a, thereby allowing the pedal body 3411 to rotate around the second pin shaft 3412 to facilitate the child's adjustment of pedaling direction.

[0214] Specifically, as shown in FIGS. 51 and 52, the pedal base 342 includes a first housing 3421 and a second housing 3422. The first housing 3421 and the second housing 3422 engage with each other to form an attachment cavity for attaching a second disassembly mechanism 343 (not shown). The side of the first housing 3421 facing away from the second housing 3422 is connected to the front fork 32. The side of the first housing 3421 facing the second housing 3422 includes an accommodating groove 3421a and an accommodating boss 3421b. The accommodating boss 3421b has a cylindrical structure and includes an accommodating cavity 3421c disposed through the axial direction of the second pin shaft 3412. The first groove wall 3421f of the storage groove 3421a includes a strip insertion hole 3421d, and the storage groove 3421a communicates with the storage cavity 3421c through the insertion hole 3421d. The second housing 3422 has spaced-apart operation holes 3422a and mounting holes 3422b. When the second housing 3422 engages with the first housing 3421, the storage boss 3421b passes through the mounting hole 3422b and protrudes from the outer surface of the second housing 3422, so that the second housing 3422, the second groove wall 3421g of the storage groove 3421a, and the cavity wall of the storage cavity 3421c together define the mounting cavity. The second groove wall 3421g is positioned opposite the first groove wall 3421f.

[0215] Specifically, as shown in FIGS. 52 and 53, the second disassembly mechanism 343 includes a second locking member 3434, an operation member 3431, and an operation reset member 3432.

[0216] In this embodiment, as shown in FIGS. 52 to 54, the portion of the second pin shaft 3412 outside the second insertion groove 3411a is surrounded by the second lock groove 3412a. The second lock member 3434 is movably disposed on the pedal base 342. In this embodiment, the second lock member 3434 has a generally strip-shaped sheet structure. The second lock member 3434 includes a second lock hole 3434a. The radial dimension of the second lock hole 3434a is larger than the radial dimension of the second pin shaft 3412.

[0217] The operating member 3431 is a quick-release button. One end of the operating member 3431 is fixedly connected to the second locking member 3434, and the other end of the operating member 3431 includes an operating portion 3431a. In this embodiment, at least a portion of the operating member 3431 and the second locking member 3434 is movably disposed within the mounting cavity. Specifically, at least a portion of the operating member 3431 is movably disposed within the accommodating groove 3421a. One end of the second locking member 3434 is connected to the operating member 3431, and the other end is inserted into the accommodating cavity 3421c through the insertion hole 3421d. The operating portion 3431a protrudes from the outer surface of the second housing 3422 through the insertion hole 3422a, facilitating user operation. The operation reset member 3432 is also disposed in the receiving groove 3421a, with one end of the operation reset member 3432 connected to or abutting the operation member 3431 and the other end abutting a second groove wall 3421g of the receiving groove 3421a. In this embodiment, the operation reset member 3432 is located on a side of the operation member 3431 away from the second lock member 3434. Optionally, the operation reset member 3432 is a spring.

[0218] Furthermore, the second locking member 3434 is operable to move between a first movable position (shown in FIG. 53) and a second movable position (shown in FIG. 54). In this embodiment, the second movable position is located in the F1 direction of the first movable position. That is, the second movable position is located above the first movable position. One end of the second pin shaft 3412, which has the second locking groove 3412a, extends into the accommodation cavity 3421c, i.e., the mounting cavity, and simultaneously passes through the second locking hole 3434a. When the pedal assembly 341 is mounted in place, the hole wall of the second locking hole 3434a closely faces the second locking groove 3412a on the second pin shaft 3412.

[0219] 53 , when the second locking member 3434 is in the first movable position, the upper side of the hole wall of the second locking hole 3434a is inserted into the second locking groove 3412a, and the operation reset member 3432 biases the operating member 3431, thereby driving the operating member 3431 to move the second locking member 3434 toward the first movable position. In this manner, the second locking member 3434 is maintained in the first movable position, and the pedal assembly 341 is connected to the pedal base 342. When it is necessary to disassemble the pedal assembly 341 from the pedal base 342, the operating portion 3431a can be pushed along the F1 direction, thereby driving the operating member 3431 to move the second locking member 3434 together along the F1 direction to the second movable position, compressing the operation reset member 3432 and disengaging the hole wall of the second locking hole 3434a from the second locking groove 3412a. In this manner, the pedal assembly 341 and the pedal base 342 are unlocked, and the pedal assembly 341 is disassembled from the pedal base 342. Note that the radial dimension of the second locking hole 3434a is larger than the radial dimension of the second pin shaft 3412, so the underside of the hole wall of the second locking hole 3434a does not engage with the second locking groove 3412a. The process of installing the pedal assembly 341 on the pedal base 342 is the reverse of the above disassembly process, and therefore will not be described in detail again.

[0220] 52, the mounting cavity includes a first limiting portion 3421e, and the operating member 3431 includes a second limiting portion 3431b, and the first limiting portion 3421e abuts against the second limiting portion 3431b when the second locking member 3434 is in the first movable position. In this embodiment, the first groove wall 3421f of the accommodating groove 3421a forms the first limiting portion 3421e, and the second limiting portion 3431b is the lower end surface of the operating member 3431. The configuration of the first limiting portion 3421e and the second limiting portion 3431b can limit the movement stroke of the second locking member 3434, thereby preventing the second locking member 3434 from moving excessively in the direction opposite to F1. At the same time, by setting the size of the operating hole 3422a on the second housing 3422, the movement stroke of the operating member 3431 and the second locking member 3434 in the F1 direction and the direction opposite to F1 can also be limited, thereby limiting the movement of the second locking member 3434 between the first movable position and the second movable position and preventing excessive movement of the second locking member 3434.

[0221] In this embodiment, two pedal devices 34 are provided, one for each front fork. 32 , making it easy for children to place their feet on the pedal bodies 3411 of the pedal devices 34 on the two sides to pedal. Of course, in other embodiments, more than two pedal devices 34 may alternatively be provided. For example, two pedal assemblies 341 having different heights and sizes may be provided on the two sides of the front wheel assembly 30 to make it easier for children of various ages or builds to ride.

[0222] In this embodiment of the child carrier, the pedal assembly 341 and the footrest assembly 630 are two separate components.

[0223] 55 to 64 schematically show a child carrier 100 according to a fourth embodiment of the present disclosure. The child carrier 100 may be, for example, a child's tricycle, a child's bicycle, etc. The child carrier allows the child's legs to rest more completely, providing a better user experience.

[0224] 55-56, the child carrier 100 in this embodiment includes a frame body 10, a leading assembly 20, a front wheel assembly 30, a rear wheel assembly 40, a seat 50, a push rod 60, and a footrest device 600. The frame body 10, leading assembly 20, front wheel assembly 30, rear wheel assembly 40, seat 50, and push rod 60 in this embodiment all have the same structures and connection relationships as the frame body 10, leading assembly 20, front wheel assembly 30, rear wheel assembly 40, seat 50, and push rod 60 in the third embodiment, with the main difference being the specific structure of the footrest device 600.

[0225] In this embodiment, as shown in FIGS. 55 and 56 , the footrest device 600 includes a footrest assembly 630, a support member 610, and a connecting member 620. The structures of the support member 610 and the connecting member 620 in this embodiment are substantially the same as those of the support member 610 and the connecting member 620 in the third embodiment, with the main difference being the footrest assembly 630 and the method of connection between the footrest assembly 630 and the support member 610. In this embodiment, the footrest assembly 630 and the pedal assembly 341 of the pedal device 34 are actually the same component. The footrest assembly 630 is detachably connected to the support member 610. When the footrest device 600 is in an in-use state, the support member 610 is in a first rotational position, and the footrest assembly 630 is attached to the support member 610. When the footrest device 600 is not in an in-use state, the support member 610 is in a second rotational position, and the footrest assembly 630 is disassembled from the support member 610.

[0226] Specifically, when the footrest device 600 is in use, as shown in FIG. 55 , the footrest assembly 630 can be attached to the support member 610, with the support member 610 at a first rotational position. In this manner, a child can rest their feet on the footrest assembly 630. When the footrest device 600 is not in use, as shown in FIG. 56 , the footrest assembly 630 can be disassembled from the support member 610, with the support member 610 rotated to a second rotational position. The disassembled footrest assembly 630 can be attached to a pedal base 342 as a pedal assembly 341 for the child to pedal. In this embodiment, the footrest assembly 630 and the pedal assembly 341 are actually the same component. The footrest assembly 630 allows a child's feet to rest when in use and can be used as a pedal assembly 341 for pedaling when not in use, which has two usage modes, does not require an additional pedal assembly 341 (or footrest assembly 630), is easy to use, helps reduce the number of components of the child carrier, and reduces manufacturing costs.

[0227] 58 to 60, the footrest device 600 further includes a first disassembly mechanism 690. The footrest assembly 630 is detachably connected to the support member 610 via the first disassembly mechanism 690. In this embodiment, two footrest assemblies 630 and two first disassembly mechanisms 690 are provided. The two footrest assemblies 630 are detachably connected to the left and right sides of the support member 610 via the two first disassembly mechanisms 690. Using one footrest assembly 630 and the corresponding first disassembly mechanism 690 as an example, each structure and their associated connection relationships will be specifically described below.

[0228] FIG. 57 is a schematic structural diagram of the connecting member 620, the support member 610, and one footrest assembly 630. FIGS. 58 and 59 are cross-sectional views of the structure shown in FIG. 57 along line DD. A first locking member 691 (described in detail below) of a first disassembly mechanism 690 in FIG. 58 is in a first locked position, and a first locking member 691 (described in detail below) of the first disassembly mechanism 690 in FIG. 59 is in a first unlocked position. Specifically, the footrest assembly 630 includes a footrest body 633 and a first pin shaft 634. The footrest body 633 is configured to hold a child's feet. The footrest body 633 has a generally rectangular parallelepiped structure. The approximate axial position of the footrest body 633 is provided with a first insertion groove 633a along its axial direction, and one end of the first locking member 691 is inserted into the first insertion groove 633a, thereby allowing the footrest body 633 to rotate around the first pin shaft 634, and allowing a child to easily adjust the pedaling direction when the footrest assembly 630 is used as the pedal assembly 341. A first locking groove 634a is disposed around a part of the first pin shaft 634 outside the first insertion groove 633a.

[0229] Specifically, as shown in FIGS. 57 to 59 , the first disassembly mechanism 690 includes a first locking member 691 and a lock reset member 692. The first locking member 691 has a substantially sheet-like structure, and a first locking hole 691a is provided substantially in the center of the first locking member 691. The radial dimension of the first locking hole 691a is larger than the radial dimension of the first pin shaft 634. The first locking member 691 is movably disposed within the support member 610, and the first locking member 691 is switchable between a first locked position and a first unlocked position. Specifically, a first accommodating cavity 617a and a second accommodating cavity 617b are disposed within the support member 610. A cavity wall of the first accommodating cavity 617a includes a first perforation 618a and a second perforation 618b facing each other. The first accommodating cavity 617a and the second accommodating cavity 617b are in communication with each other through a first perforation 618a, and the second perforation 618b connects the first accommodating cavity 617a to the outside of the support member 610. The first locking member 691 has one end located within the second accommodating cavity 617b and the other end passing through the first perforation 618a and inserted into the first accommodating cavity 617a. In this embodiment, the other end of the first locking member 691 may pass through the second perforation 618b and be located outside the support member 610. Of course, in other embodiments, the other end of the first locking member 691 may not extend outward from the support member 610. The portion of the first locking member 691 having the first locking hole 691a is generally located within the first accommodating cavity 617a.

[0230] Furthermore, as shown in FIGS. 58 to 60, the lock reset member 692 is disposed between the first lock member 691 and the support member 610, and is configured to bias the first lock member 691 to move it to the first lock position. Specifically, the lock reset member 692 is disposed in the second accommodating cavity 617b. One end of the lock reset member 692 abuts against the first lock member 691, and the other end abuts against a first cavity wall 619a of the second accommodating cavity 617b. The first cavity wall 619a is disposed to face the first perforation 618a.

[0231] As shown in FIGS. 58 to 60, the end of the first pin shaft 634 having the first locking groove 634a can be inserted into the first accommodating cavity 617a in the support member 610, and the end of the first pin shaft 634 can pass through the first locking hole 691a. When the first locking member 691 is in the first lock position, the hole wall of the first locking hole 691a is inserted into the first locking groove 634a. In this embodiment, the support member 610 has an insertion port 617c communicating with the first accommodating cavity 617a. The end of the first pin shaft 634 having the first locking groove 634a is inserted into the first accommodating cavity 617a through the insertion port 617c and abuts against the second cavity wall 619b of the first accommodating cavity 617a. The second cavity wall 619b is positioned opposite the insertion port 617c. In this manner, the insertion position of the first pin shaft 634 within the support member 610 can be limited. After the first pin shaft 634 is inserted into a predetermined position, the first pin shaft 634 passes through the first lock hole 691a, and the position of the first lock groove 634a of the first pin shaft 634 corresponds to the first lock member 691.

Alternatively, when the end of the first pin shaft 634 having the first lock groove 634a is inserted into the support member 610, the first pin shaft 634 can move the first locking member 691 such that the first locking member 691 overcomes the elastic force of the lock reset member 692 and moves from the first locked position to the first unlocked position.

[0233] Furthermore, the extension direction of the first pin shaft 634 intersects with the movement direction of the first locking member 691. That is, the extension direction of the first pin shaft 634 and the movement direction of the first locking member 691 are disposed to form an angle. In this embodiment, the extension direction of the first pin shaft 634 and the movement direction of the first locking member 691 are perpendicular to each other.
