Description

Technical Field

[0001] This application relates to child vehicles, and in particular, to child vehicles with reversing capabilities. Background Technology

[0002] To meet diverse usage needs, child vehicles such as strollers with reversible functions already exist. These child vehicles can switch between forward and backward modes. In forward mode, the child inside faces forward, while in backward mode, the child faces backward. The operator typically pushes the child vehicle from the rear. In backward mode, the child faces the operator, facilitating interaction between the operator and the child. The reversible function can be achieved by directly adjusting the rider's direction, without affecting the child inside.

[0003] For traditional child vehicles with driver-shifting functionality, in forward-facing mode, the child's center of gravity is typically closer to the rear wheel in the current direction of travel. However, when shifting to rear-facing mode, the rear wheel becomes the front wheel. Since the child's seat position relative to the frame remains unchanged, the child's center of gravity shifts closer to the front wheel in the current direction of travel (i.e., the rear wheel in forward-facing mode). In this situation, pushing the child vehicle in rear-facing mode becomes more difficult, especially when going uphill or up stairs. Summary of the Invention

[0089] In the following description, various aspects of this application will be described. Specific details are set forth for purposes of explanation in order to provide a thorough understanding of this application. It will be apparent to those skilled in the art that other embodiments of this application differ in detail without affecting their essence. Therefore, this application is not limited to what is shown in the drawings and described in the specification, but only as indicated in the appended claims, and the appropriate scope of this application shall be determined only by the broadest interpretation of the claims.

[0090] When a feature or element is referred to herein as "on another feature or element," it may be directly on the other feature or element, or there may be intermediate features and / or elements present. Conversely, when a feature or element is referred to herein as "directly" on another feature or element, there are no intermediate features or elements present. It should also be understood that when a feature or element is referred to herein as "connected," "attached," or "joined" to another feature or element, it may be directly connected, attached, or joined to the other feature or element, or there may be intermediate features or elements present. Conversely, when a feature or element is referred to herein as "directly connected," "directly attached," or "directly joined" to another feature or element, there are no intermediate features or elements present.

[0091] Spatial terms such as “below,” “under,” “above,” and “over” are used herein for descriptive purposes, particularly to describe the positional relationship between one feature or element and another, as shown in the figures. It should be understood that spatial terms are intended to include different orientations of the device in use or operation, in addition to those shown in the figures. For example, if the device in the figure is inverted, a feature or element described herein as “below” other features or elements would be oriented “above” other features or elements. Thus, the exemplary term “below” can include both above and below orientations. The device may also be oriented otherwise (rotated 90 degrees or in other directions), and the spatially related descriptions used herein are interpreted accordingly. Similarly, unless otherwise specified, terms such as “up,” “down,” “vertical,” and “horizontal” used herein are for illustrative purposes only.

[0092] While the terms “first” and “second” may be used herein to describe various features or elements, these features or elements should not be limited by these terms unless otherwise specified. These terms are used to distinguish one feature or element from another. Therefore, a first feature or element discussed below may be referred to as a second feature or element, and similarly, a second feature or element discussed below may be referred to as a first feature or element. In this document, “multiple” means at least two, such as two, three, etc., unless otherwise explicitly and specifically defined.

[0093] In this text, "forward / backward direction" refers to the longitudinal direction of the child vehicle as seen from the perspective of a child inside the vehicle, and "left / right direction" refers to the lateral direction of the child vehicle as seen from the perspective of a child inside the vehicle. "Forward travel direction" refers to the direction the child vehicle travels when pushed forward in the forward / backward direction. "Reverse travel direction" refers to the direction the child vehicle travels when pulled backward in the forward / backward direction. "Front" of the child vehicle indicates its orientation towards the forward travel direction in forward-facing mode; "Rear" indicates its orientation away from the forward travel direction in forward-facing mode; "Left" indicates the left side when viewed from behind the child vehicle; and "Right" indicates the right side when viewed from behind the child vehicle. Other terms like "front," "rear," "left," and "right" mentioned in the text have similar meanings. It should be noted that, unless otherwise explicitly stated or limited, the directional terms such as "front," "rear," "left," and "right" used in this document for children's vehicles are based on the directions shown in the accompanying drawings. Arrows L and R in the drawings schematically indicate the "left" and "right" directions, while arrows F and B schematically indicate the "front" and "rear" directions.

[0094] The following description uses a stroller as an example to describe the child vehicle provided in this application. Strollers include, but are not limited to, sitting strollers, reclining strollers, and convertible strollers.

[0095] Figure 1 and Figure 3 A child vehicle in forward and rearward modes, respectively, according to an embodiment of the first aspect of this application, is shown; the seat is omitted for clarity. Figure 1 and Figure 3 As shown, the child vehicle 1 includes a frame 11 and a handlebar 12 rotatably mounted on the frame 11. The frame 11 includes a front leg 111 and a rear leg 112. The end of the front leg 111 is connected to a front wheel assembly 1111, and the end of the rear leg 112 is connected to a rear wheel assembly 1121. The upper ends of the front leg 111 and the upper ends of the rear leg 112 are rotatably connected to each other. Optionally, the frame 11 also includes a side armrest 113 and a center member 114. The upper ends of the front leg 111 and the upper ends of the rear leg 112 are rotatably connected to the front end of the side armrest 113. The upper end of the center member 114 is rotatably connected to the rear end of the side armrest 113, and the lower end of the center member 114 is rotatably connected to the rear leg 112.

[0096] The child vehicle 1 also includes a first support 13 and a second support 14. The first support 13 is connected to the frame 11. Specifically, one end of the first support 13 is rotatably connected to the front leg 111, and the other end of the first support 13 is connected to the neutral member 114 connected to the rear leg 112. Figure 1 and Figure 3 As shown, when the child carrier 1 is placed on a horizontal surface in its unfolded state, the first support 13 extends generally in the horizontal direction. The second support 14 is movably arranged above the first support 13. The second support 14 can be referred to as the "upper support," and the first support 13 can be referred to as the "lower support." Optionally, the first support 13 and the second support 14 can be constructed of tubular components; correspondingly, the first support 13 and the second support 14 can also be referred to as the "lower tubular mechanism" and the "upper tubular mechanism," respectively. The second support 14 is used to mount a seat (not shown). The seat can be mounted to the second support 14 using fasteners such as threaded fasteners, pin fasteners, or rivet fasteners, or it can be mounted to the second support 14 using permanent connections such as welding or bonding, or it can be detachably mounted to the second support 14 using snap-fit ​​or plug-in connections.

[0097] For example, the rider 12 is rotatably connected to the first bracket 13, such that the rider 12 is rotatable relative to the frame 11. For instance, the rider 12 can rotate from... Figure 1 The first angular position shown is rotated in the first rotation direction D1 to... Figure 3 The second angular position is shown. (As shown) Figure 1As shown, when driver 12 is in the first angle position, driver 12 is roughly located at the rear of child vehicle 1, and child vehicle 1 is in forward-facing mode. At this time, the forward direction of travel of child vehicle 1 is... Figure 1 The first direction F1 indicates the direction, which corresponds to the front of the child vehicle 1. The first angular position can also be referred to as the driver 12's forward operating position. For example... Figure 3 As shown, when driver 12 is in the second angle position, driver 12 is roughly located in front of child vehicle 1, and the child vehicle is in rearward mode. At this time, the forward direction of travel of child vehicle 1 is... Figure 3 The direction indicated by the second direction F2 corresponds to the rear of the child vehicle 1. This second angular position can also be referred to as the rearward use position of the rider 12. In this document, the movement of the rider 12 from the first angular position (i.e., the forward use position) to the second angular position (i.e., the rearward use position), or from the second angular position to the first angular position, is referred to as a reversal of the rider 12. The reversal of the rider 12 causes the child vehicle 1 to switch between forward and rearward modes.

[0098] When the rider 12 rotates relative to the frame 11 to switch the child vehicle 1 between forward and backward modes, the rider 12 drives the second support 14 to move relative to the first support 13 in the fore-and-aft direction of the child vehicle 1. For example, when the rider 12 rotates from the frame 11 to the child vehicle 1, the second support 14 moves relative to the first support 13 in the fore-and-aft direction of the child vehicle 1. Figure 1 The forward use position shown is rotated in the first rotation direction D1 to... Figure 3In the rearward use position shown, the second support 14 is driven to move relative to the first support 13 in a first direction F1, such that the second support 14 moves from a first position relative to the frame 11 to a second position in the fore-aft direction of the child carrier 1. In the second position, compared to the first position, the front end of the second support 14 is further away from the rear wheel assembly 1121 in the fore-aft direction of the child carrier 1. That is, when the rider 12 rotates from the forward use position to the rearward use position to switch the child carrier 1 from forward mode to rearward mode, the second support 14 moves forward relative to the frame 11 in the first direction F1. The seat mounted on the second support 14 moves forward relative to the frame 11 along with the second support 14. Accordingly, the center of gravity of the child carrier 1 moves forward relative to the frame 11 along the first direction F1. Furthermore, since the child placed in the child carrier 1 also moves forward relative to the frame 11 along with the second support 14, the child's center of gravity also moves forward relative to the frame 11 along the first direction F1. Compared to the forward-facing mode, in the rearward-facing mode, the overall center of gravity of the child vehicle 1 with the child is closer to the front wheel assembly 1111. Since the front wheel assembly 1111 of the child vehicle 1 actually acts as the rear wheel in the rearward-facing mode, the changed overall center of gravity of the child vehicle 1 will be closer to the front wheel assembly 1111, which acts as the rear wheel in the rearward-facing mode, that is, closer to the operator. Therefore, it will be easier to push the child vehicle 1 in this situation.

[0099] When driver 12 from Figure 3 The rearward use position shown rotates to a second rotation direction D2, which is opposite to the first rotation direction D1. Figure 1 In the forward-facing position, the second support 14 is driven to move relative to the first support 13 in a second direction F2, opposite to the first direction F1, causing the second support 14 to move from a second position relative to the frame 11 to a first position. That is, when the rider 12 rotates from the rearward-facing position to the forward-facing position to switch the child vehicle 1 from rearward mode to forward mode, the second support 14 moves rearward relative to the frame 11 in the second direction F2. The seat mounted on the second support 14 moves rearward relative to the frame 11 along with the second support 14. The change in the center of gravity of the child vehicle 1 when switching from rearward mode to forward mode is the opposite of the change when switching from forward mode to rearward mode, and will not be described further here.

[0100] According to the child vehicle 1 of this application, the second support 14 is driven to move relative to the first support 13 in the front-rear direction of the child vehicle 1 by the rotation of the rider 12 relative to the frame 11, which can effectively improve the adjustment convenience and use comfort of the child vehicle 1.

[0101] Reference Figures 1 to 4The child vehicle also includes a pivot 121 and a drive mechanism 16. The pivot 121 is rotatably connected to a first support 13. The rider 12 is rotatably connected to the first support 13 via the pivot 121. One end of the drive mechanism 16 is fixedly connected to the pivot 121, and the other end is rotatably connected to a second support 14. Optionally, the other end of the drive mechanism 16 is rotatably connected to the second support 14 via a first connector 161. The first connector 161 may be, for example, in the form of a rotating shaft. At least one of the drive mechanism 16 and the second support 14 is rotatable about the first connector 161 to allow rotation of the drive mechanism 16 relative to the second support 14. One end of the rider 12 is fixedly connected to the pivot 121. The drive mechanism 16 is configured to drive the second support 14 relative to the first support 13 when the rider 12 rotates relative to the frame 11.

[0102] For example, the pivot 121 is a shaft-like structure. The pivot 121 passes through the neutral member 114, and its first end extending from the neutral member 114 is fixedly connected to the rider 12. Its second end extending from the neutral member 114 passes through the first bracket 13 and is then fixedly connected to the drive mechanism 16. Figure 2 and Figure 4 Only a portion of the neutral component 114 is shown. The second end of the pivot 121, which connects to the drive mechanism 16, can be configured to have a non-circular cross-section such as a rectangle, ellipse, rhombus, or hexagon. The drive mechanism 16 can have a fixing hole (not shown) that matches the cross-sectional shape of the second end of the pivot 121. The second end of the pivot 121 is adapted to be inserted into the fixing hole of the drive mechanism 16, and the drive mechanism 16 is fixedly connected to the second end of the pivot 121 by, for example, an interference fit. When the rider 12 rotates, the drive mechanism 16 will rotate with the rider 12 due to the drive of the pivot 121, which is fixedly connected between the rider 12 and the drive mechanism 16. It is understood that the second end of the pivot 121 can also be fixedly connected to the drive mechanism 16 by welding, bonding, keying, pinning, riveting, etc.

[0103] The rotation direction of the drive mechanism 16 is the same as the rotation direction of the rider 12. For example, when the rider 12 moves from... Figure 1 The forward use position shown is oriented towards the first rotation direction D1. Figure 3 When the rider 12 rotates to the rearward position as shown, the drive mechanism 16 also rotates in the first rotation direction D1 under the action of the rider 12. Figure 3 The rearward use position shown is oriented towards the second rotation direction D2. Figure 1When the rider 12 rotates to the forward operating position shown, the drive mechanism 16 also rotates in the second rotation direction D2 under the drive of the rider 12. Optionally, the drive mechanism 16 may consist of multiple components that are mutually driven and connected. When the rider 12 rotates relative to the frame 11, at least one of these components, which is fixedly connected to the pivot 121, rotates synchronously with the rider 12 to drive the other components among these components. The rotation angle of the other components may be smaller than the rotation angle of the rider 12.

[0104] Continue to refer to Figures 1 to 4 The child vehicle also includes a first support mechanism 15, which is disposed between the first bracket 13 and the second bracket 14. The first support mechanism 15 increases the height of the second bracket 14 within the frame 11, thereby increasing the seat height mounted on the second bracket 14. Optionally, a drive mechanism 16 disposed between the first bracket 13 and the second bracket 14 also serves to support the second bracket 14. The drive mechanism 16, together with the first support mechanism 15, supports the second bracket 14 at a predetermined height above the first bracket 13. The drive mechanism 16 may also be referred to as a "support structure".

[0105] The first support mechanism 15 includes at least one first support member 151, each first support member 151 being disposed between the first bracket 13 and the second bracket 14. The first support member 151 is, for example, a support rod. Exemplarily, in the illustrated embodiment, the first support mechanism 15 includes two first support members 151. In other embodiments, the first support mechanism 15 may include only one first support member 151, or it may include three or more first support members 151. When the first support mechanism 15 includes multiple first support members 151, the multiple first support members 151 are spaced apart from each other. Each first support member 151 has a first end and a second end opposite to each other; the first end of the first support member 151 is fixedly connected to the first bracket 13, and the second end of the first support member 151 is slidably connected to the second bracket 14. Optionally, the first support member 151 is arranged substantially perpendicular to the first bracket 13. The vertically arranged first support member 151 can withstand a larger vertical load and can, together with the horizontally arranged first bracket 13 and second bracket 14, form a stable support structure. The first end of the first support member 151 can be fixedly connected to the first bracket 13 by a fastener 1511. The fastener 1511 can be a threaded fastener, a pin fastener, a rivet fastener, etc. The first end of the first support member 151 can also be fixedly connected to the first bracket 13 by means such as welding or bonding.

[0106] The second support 14 is provided with a first groove structure 141, which provides a path for the movement of the second support 14 relative to the first support 13. The first groove structure 141 extends generally along the front-rear direction of the child carrier. The first groove structure 141 is slidably connected to the second end of the first support member 151. The first groove structure 141 can be a linear groove or slot. The first groove structure 141 can be located in the middle or bottom of the second support 14 in the vertical direction. Figures 1 to 4 In the illustrated embodiment, the first groove structure 141 is located in the middle of the second support 14. A first connecting mechanism 1512 is provided at the second end of the first support member 151, and the first connecting mechanism 1512 is slidably inserted into or abuts against the first groove structure 141. Exemplarily, when the first groove structure 141 is located in the middle of the second support 14, the first connecting mechanism 1512 is inserted into the cavity formed by the first groove structure 141. The first connecting mechanism 1512 is a shaft-like structure or a roller-like structure. Contact with the first groove structure 141 via a shaft-like or roller-like structure helps to reduce the sliding friction between the first connecting mechanism 1512 and the first groove structure 141. Therefore, the second support 14 can move smoothly relative to the first support 13 along a movement path defined by the first groove structure 141.

[0107] The sliding engagement of the first connecting mechanism 1512 with the first groove structure 141 allows the second support 14 to move relative to the first support 13 in the fore-and-aft direction of the child carrier 1. For example, when the rider 12... Figure 1 The forward use position shown is oriented towards the first rotation direction D1. Figure 3 When rotated to the rearward use position as shown, the drive mechanism 16, driven by the rider 12, drives the second support 14 in the first direction F1 relative to the first support 13 from... Figure 2 The first moving position shown is moved to Figure 4 The second moving position is shown. When driver 12 moves from... Figure 3 The rearward use position shown is oriented towards the second rotation direction D2. Figure 1 When rotated to the forward use position shown, the drive mechanism 16, driven by the rider 12, drives the second support 14 in the second direction F2 relative to the first support 13 from... Figure 4 The second moving position shown is moved to Figure 2 The first moving position is shown.

[0108] Figures 5 to 8 This application illustrates another embodiment of a child vehicle according to the present application. The following will mainly describe the differences between this embodiment and the above embodiments, and the same or similar aspects as the above embodiments will not be repeated.

[0109] The main difference between this embodiment and the previous embodiment lies in the position of the first groove structure 141 within the second support 14. In this embodiment, the first groove structure 141 is located at the bottom of the second support 14. The first connecting mechanism 1512 abuts against the cavity formed by the first groove structure 141. Specifically, the first groove structure 141 can be placed on the first connecting mechanism 1512. Similar to the previous embodiment, the first connecting mechanism 1512 is a shaft-like structure or a roller-like structure to facilitate the sliding of the first groove structure 141 on the first connecting mechanism 1512.

[0110] Figures 9 to 12 This application illustrates another embodiment of a child vehicle according to the present application. The following will mainly describe the differences between this embodiment and the above embodiments, and the same or similar aspects as the above embodiments will not be repeated.

[0111] In this embodiment, the first support mechanism 15 includes a second support member 152. The second support member 152 is, for example, a support rod. The second support member 152 has opposing first and second ends. The first end of the second support member 152 is rotatably connected to the first bracket 13, and the second end of the second support member 152 is slidably connected to the second bracket 14. Optionally, the first end of the second support member 152 is rotatably connected to the first bracket 13 via a second connector 1521. The second connector 1521 can be, for example, in the form of a rotating shaft. At least one of the second support member 152 and the first bracket 13 is rotatable about the second connector 1521 to allow rotation of the second support member 152 relative to the first bracket 13. The second support member 152 is configured such that when the rider 12 rotates relative to the frame 11 to drive the second bracket 14 to move relative to the first bracket 13, the second support member 152 rotates relative to the first bracket 13, and the direction of rotation of the second support member 152 is opposite to the direction of rotation of the rider 12.

[0112] The second bracket 14 is provided with a second support mechanism 142, which has an arc-shaped second groove structure 1421. The second groove structure 1421 provides a movement path for the second bracket 14 relative to the first bracket 13. The second end of the second support member 152 is slidably connected to the second groove structure 1421. When the second bracket 14 moves relative to the first bracket 13, the second end of the second support member 152 is adapted to slide along the second groove structure 1421 from one end to the other end. The second support mechanism 142 can be integrally formed with the second bracket 14 or be a separate structure. In the case where the second support mechanism 142 and the second bracket 14 are separate structures, the second support mechanism 142 and the second bracket 14 are manufactured separately and can then be installed together by fasteners such as threaded fasteners, pin fasteners, rivet fasteners, etc., or fixed together by permanent connection methods such as welding or bonding.

[0113] The second groove structure 1421 can be an arc-shaped recess or slot. Similar to the first groove structure 141, the second groove structure 1421 can be located in the middle or bottom of the second support mechanism 142 in the vertical direction. A second connecting mechanism 1522 is provided at the second end of the second support member 152, and the second connecting mechanism 1522 is slidably inserted into or abuts against the second groove structure 1421. For example, when the second groove structure 1421 is located in the middle of the second support mechanism 142, the second connecting mechanism 1522 is inserted into the cavity formed by the second groove structure 1421. When the second groove structure 1421 is located at the bottom of the second support mechanism 142, the second connecting mechanism 1522 abuts against the cavity formed by the second groove structure 1421. The second connecting mechanism 1522 is a shaft-like structure or a roller-like structure. Contact with the second groove structure 1421 through a shaft-like structure or a roller-like structure helps to reduce the sliding friction between the second connecting mechanism 1522 and the second groove structure 1421. Thus, the second support 14 can move smoothly relative to the first support 13 along the movement path defined by the second groove structure 1421.

[0114] The second support 152 rotates relative to the first bracket 13, and the second connecting mechanism 1522 slides with the second groove structure 1421, allowing the second bracket 14 to move relative to the first bracket 13 in the fore-and-aft direction of the child carrier 1. For example, when the rider 12 moves from... Figure 9 The forward use position shown is oriented towards the first rotation direction D1. Figure 11 When rotated to the rearward use position as shown, the drive mechanism 16, driven by the rider 12, drives the second support 14 in the first direction F1 relative to the first support 13 from... Figure 10 The first moving position shown is moved to Figure 12 The second moving position is shown. During this process, the second support 152 rotates relative to the first bracket 13 in a second rotation direction D2, causing the second end of the second support 152 to move from... Figure 10 The front end of the second groove structure 1421 shown slides along the second groove structure 1421 to Figure 12 The rear end of the second slot structure 1421 is shown. When the rider 12 from Figure 11 The rearward use position shown is oriented towards the second rotation direction D2. Figure 9 When rotated to the forward use position shown, the drive mechanism 16, driven by the rider 12, drives the second support 14 in the second direction F2 relative to the first support 13 from... Figure 12 The second moving position shown is moved to Figure 10 The first moving position is shown. During this process, the second support 152 rotates relative to the first bracket 13 in a first rotation direction D1, causing the second end of the second support 152 to move from... Figure 12The rear end of the second groove structure 1421 shown slides along the second groove structure 1421 to Figure 10 The front end of the second groove structure 1421 shown.

[0115] Figure 13 and Figure 14 A child vehicle in forward and rearward modes, according to an embodiment of the second aspect of this application, is shown, with the seat removed for ease of illustration. Figure 13 and Figure 14 As shown, the child vehicle 2 includes a frame 21, a rider 22 pivotally mounted on the frame 21, and a movable support 23 slidably mounted on the frame 21. The frame 21 includes a front leg 211 and a rear leg 212. The end of the front leg 211 is connected to a front wheel assembly 2111, and the end of the rear leg 212 is connected to a rear wheel assembly 2121. The upper ends of the front leg 211 and the upper ends of the rear leg 212 are pivotally connected to each other. The frame 21 also includes a support member 213, the rider 22 is pivotally connected to the support member 213, and the movable support 23 is slidably connected to the support member 213. The seat (not shown) can be installed on the movable support 23 by fasteners such as threaded fasteners, pin fasteners, or rivet fasteners, or by permanent connection methods such as welding or bonding, or by detachable installation on the movable support 23 by snap-fit ​​or plug-in methods.

[0116] The rider 22 is pivotable relative to the frame 21. For example, the rider 22 can pivot from... Figure 13 The first angular position shown is rotated to Figure 14 The second angular position is shown. (As shown) Figure 13 As shown, when rider 22 is in the first angle position, rider 22's grip (in) Figure 13 and Figure 14 (Not shown in the image) is located at the rear of child vehicle 2, and child vehicle 2 is in forward-facing mode. At this time, the forward direction of travel for child vehicle 2 is... Figure 13 The first direction F1 indicates the direction, which corresponds to the front of the child vehicle 2. The first angular position can also be referred to as the driver's forward operating position 22. For example... Figure 14 As shown, when the rider 22 is in the second angle position, the handlebars of the rider 22 are located at the front of the child vehicle 2, and the child vehicle is in rearward mode. At this time, the forward direction of travel of the child vehicle 2 is... Figure 14The direction indicated by the second direction F2 corresponds to the rear of the child vehicle 2. This second angular position can also be referred to as the rearward use position of the rider 22. In this text, the movement of the rider 22 from the first angular position (i.e., the forward use position) to the second angular position (i.e., the rearward use position), or from the second angular position to the first angular position, is referred to as a reversal of the rider 22. The reversal of the rider 22 causes the child vehicle 2 to switch between forward and rearward modes.

[0117] The rotation of rider 22 relative to frame 21 drives movable support 23 to slide along support member 213. For example, when rider 22 moves from... Figure 13 Rotate to the forward use position shown Figure 14 In the rearward use position shown, the drive support 23 is moved from a first position relative to the frame 21 to a second position. Compared to the first position, in the second position, the drive support 23 is further away from the rear wheel assembly 2121 in the longitudinal direction (i.e., the fore-and-aft direction) of the child carrier 2. That is, when the rider 22 rotates from the forward use position to the rearward use position to switch the child carrier 2 from forward mode to rearward mode, the drive support 23 moves forward relative to the frame 21 along the longitudinal direction of the child carrier 2. The seat mounted on the drive support 23 moves forward relative to the frame 21 along with the drive support 23. Accordingly, the center of gravity of the child carrier 2 moves forward relative to the frame 21 along the longitudinal direction of the child carrier 2. Furthermore, since the child placed in the child carrier 2 also moves forward relative to the frame 21 with the drive support 23, the child's center of gravity also moves forward relative to the frame 21 along the longitudinal direction of the child carrier 2. Compared to the forward-facing mode, in the rearward-facing mode, the overall center of gravity of the child vehicle 2 with the child on it is closer to the front wheel assembly 2111. Since the front wheel assembly 2111 of the child vehicle 2 actually acts as the rear wheel in the rearward-facing mode, the changed overall center of gravity of the child vehicle 2 will be closer to the front wheel assembly 2111, which acts as the rear wheel in the rearward-facing mode, that is, closer to the operator. Therefore, it will be easier to push the child vehicle 2 in this situation.

[0118] When driver 22 from Figure 14 Rotate to the rearward use position shown Figure 13 When in the forward-facing position, the drive support 23 is moved from the second position relative to the frame 21 to the first position. That is, when the rider 22 rotates from the rearward-facing position to the forward-facing position to switch the child vehicle 2 from rearward mode to forward mode, the drive support 23 moves rearward relative to the frame 21 along the longitudinal direction of the child vehicle 2. The seat mounted on the drive support 23 moves rearward relative to the frame 21 along with the drive support 23. The change in the center of gravity of the child vehicle 2 when switching from rearward mode to forward mode is the opposite of the change when switching from forward mode to rearward mode, and will not be described further here.

[0119] In this embodiment, the child carrier 2 has a generally symmetrical structure, meaning that the left and right sides of the child carrier 2 have largely the same construction. For example, the frame 21 includes two support members 213 located on the left and right sides, and two movable supports 23 are slidably connected to a corresponding support member 213. The two support members 213 have the same construction, and the two movable supports 23 also have the same construction. The description below using one side of the child carrier 2 as an example also applies to the other side of the child carrier 2; therefore, the other side of the child carrier 2 will not be described in detail.

[0120] Reference Figures 15 to 18 The frame 21 also includes side armrests 214 and a center member 215. The upper ends of the front foot 211 and the rear foot 212 are pivotally connected to the front end of the side armrest 214. The upper end of the center member 215 is pivotally connected to the rear end of the side armrest 214, and the lower end of the center member 215 is pivotally connected to the rear foot 212. One end of the support member 213 is pivotally connected to the front foot 211, and the other end of the support member 213 is pivotally connected to the center member 215 connected to the rear foot 212. The support member 213 includes a support body 2131 extending substantially in the longitudinal direction of the child vehicle 2. A movable bracket 23 is slidably fitted onto the support body 2131, and the movable bracket 23 can move in the longitudinal direction of the child vehicle 2 by sliding relative to the support body 2131.

[0121] The neutral member 215 is provided with a first engaging portion 2151, and the front foot 211 is provided with a second engaging portion 2112. The rider 22 is provided with an engaging member 221, which can be operated by the operator to selectively engage or disengage with either the first engaging portion 2151 or the second engaging portion 2112. For example, when the rider 22 rotates relative to the frame 21 to a forward-facing position, the operator can operate the engaging member 221 to engage with the first engaging portion 2151, thereby locking the rider 22 in the forward-facing position, and correspondingly, the child vehicle 2 remains in the forward-facing mode. In this case, when the operator operates the engaging member 221 to disengage from the first engaging portion 2151, the rider 22 is allowed to rotate relative to the frame 21 from the forward-facing position to the rearward-facing position. At this time, the operator can operate the locking piece 221 to engage with the second locking part 2112, thereby locking the rider 22 in the rear-facing use position, and correspondingly, the child vehicle 2 remains in the rear-facing use mode.

[0122] Reference Figure 17 and Figure 18The rider 22 has a pivot end 222 pivotally connected to the frame 21, the pivot end 222 being pivotable relative to the support member 213 about a first pivot axis X1. The other end of the rider 22 opposite to the pivot end 222 is a free end (not shown). The child vehicle 2 also includes a drive member 24, which is connected to the rider 22 offset from the pivot end 222, i.e., the connection position of the drive member 24 to the rider 22 is close to the pivot end 222 where the drive member 24 is pivotally connected to the rider 22, but does not overlap with the pivot end 222. In particular, the drive member 24 is fixed to the rider 22 at a position offset from the pivot end 222 toward the free end. When the rider 22 rotates relative to the support member 213 about the first pivot axis X1, the drive member 24 moves along an arc trajectory about the first pivot axis X1. The drive member 24 is adapted to abut against the movable support 23 and is configured to push the movable support 23 as the rider 22 rotates relative to the frame 21, causing the movable support 23 to slide relative to the frame 21 along the longitudinal direction of the child vehicle (i.e., the first direction F1 or the second direction F2). For example, as the rider 22 rotates relative to the frame 21 from a forward use position to a rearward use position, the drive member 24 pushes the movable support 23, causing the movable support 23 to slide from... Figure 17 The position shown slides relative to the frame 21 along the first direction F1. Figure 18 The position shown. Conversely, during the rotation of rider 22 relative to frame 21 from rearward use position to forward use position, drive member 24 pushes movable bracket 23, causing movable bracket 23 to move from... Figure 18 The position shown is along the second direction F2 (as shown) Figure 14 (As shown) Slides relative to frame 21 to Figure 17 The location shown.

[0123] Reference Figures 19 to 21 The movable support 23 includes a movable support body 231 and a sliding sleeve 232. The sliding sleeve 232 is fixed to the movable support body 231 and slidably fitted onto the support member 213. The sliding sleeve 232 is suitable for mounting the seat plate (not shown). The seat plate can be installed on the sliding sleeve 232 using fasteners such as threaded fasteners, pin fasteners, and rivet fasteners, or it can be installed on the sliding sleeve 232 by permanent connection methods such as welding or bonding, or it can be detachably installed on the sliding sleeve 232 by snap-fit ​​or plug-in engagement.

[0124] The movable support body 231 and the sliding sleeve 232 are fixedly disposed relative to each other. When the sliding sleeve 232 slides along the support member 213, the movable support body 231 moves together with the sliding sleeve 232. In this embodiment, the movable support body 231 and the sliding sleeve 232 are integrally formed. In some other embodiments, the movable support body 231 and the sliding sleeve 232 may also be manufactured separately and then fixed together by a permanent connection method such as welding or bonding.

[0125] The movable support body 231 is provided with a movable groove 2311. One end of the drive member 24 is fixed to the rider 22, and the other end of the drive member 24 is rotatably and slidably connected to the movable groove 2311. One end of the drive member 24 can be directly connected to the rider 22 by a permanent connection method such as welding or bonding, or by a fastener such as a threaded fastener, a pin fastener, or a rivet fastener. In this embodiment, the movable groove 2311 is an elongated slot extending generally in the vertical direction (i.e., perpendicular to the longitudinal and transverse directions). The movable groove 2311 has opposing first sidewalls 2311a and second sidewalls 2311b. The end of the drive member 24 connected to the movable support body 231 is slidably embedded in the movable groove 2311. When the drive member 24 moves with the rotation of the rider 22, it is adapted to push against one of the first sidewall 2311a and the second sidewall 2311b to drive the movable bracket 23 to slide along the support member 213. Through the sliding engagement of the drive member 24 with the movable groove 2311, during the movement of the drive member 24, one end of the drive member 24 embedded in the movable groove 2311 is rotatable relative to the movable groove 2311 and can slide along the movable groove 2311. The movable groove 2311 provides a space for the end of the drive member 24 connected to the movable bracket body 231, allowing the drive member 24 to move along an arc centered on the first pivot axis X1 as the rider 22 rotates, as described above.

[0126] In this embodiment, the movable support body 231 can be driven to move forward or backward relative to the frame 21 by pushing either the opposing first sidewall 2311a or the second sidewall 2311b of the movable slot 2311 with the drive member 24. For example, during the process of the rider 22 rotating relative to the frame 21 from a forward use position to a rearward use position, the drive member 24 pushes the first sidewall 2311a of the movable slot 2311, causing the movable support 23 to move forward or backward along the support member 213 in the first direction F1. Figure 19 Slide to the position shown Figure 20 The position shown. Conversely, during the rotation of rider 22 relative to frame 21 from rearward use position to forward use position, drive member 24 pushes against the second sidewall 2311b of movable slot 2311, so that movable bracket 23 moves along support member 213 in the second direction F2 (e.g. Figure 14 (As shown) from Figure 20 Slide to the position shown Figure 19 The location shown.

[0127] Reference Figure 17 , Figure 18 and Figure 21The neutral member 215 is provided with a notch 2154, which is configured to accommodate at least a portion of the drive member 24 between the movable support 23 and the rider 22 when the rider 22 is in the forward-facing position. Thus, the drive member 24 will not interfere with the neutral member 215 when the rider 22 is in the forward-facing position. The notch 2154 can also be referred to as a clearance opening. Specifically, the neutral member 215 includes a first neutral member 2152 and a second neutral member 2153. One end of the first neutral member 2152 is pivotally connected to the side armrest 214, and the other end is pivotally connected to the second neutral member 2153. One end of the second neutral member 2153 is pivotally connected to the first neutral member 2152, and the other end is pivotally connected to the rear footrest 212. A first engaging portion 2151 is disposed on the upper part of the first neutral member 2152, and a drive member 24 is disposed on the lower part of the first neutral member 2152. The rider 22 is pivotally connected to the support member 213 via a pivot axis (not shown) passing through the first neutral member 2152 and the second neutral member 2153. That is, the rider 22, the first neutral member 2152, the second neutral member 2153, and the support member 213 can pivot relative to each other about the same pivot axis (i.e., pivot axis X1). When the rider 22 is in the forward use position, the drive member 24 occupies the notch 2154 formed in the first neutral member 2152. When the rider 22 rotates relative to the support member 213 towards the rearward use position, the drive member 24 moves out of the notch 2154 and away from the neutral member 215. Under the pushing force of the drive member 24, the movable bracket 23, slidably connected to the support member 213, moves away from the neutral member 215. It is understood that in other embodiments, the neutral member 215 may not have a notch 2154. As long as the driving member 24 is offset so that the driving member 24 does not interfere with the neutral member 215 when the rider 22 is in the forward use position.

[0128] In this embodiment, the rotation of the rider 22 will cause the drive member 24 to rotate synchronously. The drive member 24 pushes the movable support 23, causing the movable support 23 to slide forward or backward along the support member 213. This allows the movable support 23 to move forward or backward relative to the frame 21 in the longitudinal direction of the child vehicle 2. Consequently, the seat mounted on the movable support 23 will move forward or backward relative to the frame 21 along with the movable support 23. In particular, when the rider 22 rotates to switch the child vehicle 2 from forward-facing mode to rear-facing mode, the seat will move forward relative to the frame 21 along with the movable support 23. This results in the overall center of gravity of the child vehicle 2 being closer to the actual rear wheel in rear-facing mode. Therefore, pushing the child vehicle in rear-facing mode will be less strenuous.

[0129] Figures 22 to 25This illustration shows another embodiment of a child vehicle according to a second aspect of this application. The main difference between this embodiment and the above embodiments lies in the manner in which the movable support is moved when the rider rotates. In the following description of this embodiment, the same or similar aspects as those in the above embodiments will not be repeated.

[0130] In this embodiment, the drive member 24 is configured to push the movable support 23 only when the rider 22 rotates relative to the frame 21 in a first rotation direction D1, causing the movable support 23 to slide from a first position to a second position relative to the frame 21 along the longitudinal direction of the child carrier 2. When the rider 22 rotates relative to the frame 21 in a second rotation direction D2, opposite to the first rotation direction D1, the drive member 24 cannot push the movable support 23. For example, the first rotation direction D1 corresponds to the direction the rider 22 faces when rotating from a forward use position to a rearward use position, and the second rotation direction D2 corresponds to the direction the rider 22 faces when rotating from a rearward use position to a forward use position. Figure 22 In the diagram, the first rotation direction D1 is shown as counterclockwise, while the second rotation direction D2 is shown as clockwise. The first position of the movable support 23 corresponds to the child vehicle 2 being in the forward-facing mode, that is, the position of the movable support 23 when the rider 22 is in the forward-facing use position. For example... Figure 22 The position of the movable support 23 is shown. The second position of the movable support 23 corresponds to the position of the movable support 23 when the child vehicle 2 is in the rear-facing mode, that is, when the rider 22 is in the rear-facing use position. For example, Figure 23 The position of the movable support 23 is shown.

[0131] In this embodiment, the movable support body 231 does not have the movable groove 2311 described in the above embodiment, and the drive member 24 abuts against the abutment portion 2312 of the movable support body 231. The abutment portion 2312 is located, for example, at the rear edge of the movable support body 231. Only the abutment portion 2312 of the movable support body 231 can abut against the drive member 24. During the rotation of the rider 22 relative to the frame 21 in a first rotation direction D1 (specifically, from the forward use position to the rearward use position), since the drive member 24 is located behind the abutment portion 2312 in its current direction of movement, the drive member 24 can push against the abutment portion 2312, so that the movable support 23 moves along the support member 213 from... Figure 22 The first position shown is slid to Figure 23 The second position is shown. During the rotation of the rider 22 relative to the frame 21 in the second rotation direction D2 (in particular, from the rearward use position to the forward use position), the drive member 24 is unable to push against the abutment 2312 because it is located in front of the abutment 2312 in its current direction of movement.

[0132] The child vehicle 2 includes an elastic element 25 disposed between a support member 213 and a sliding sleeve 232. The elastic element 25 is configured to push the sliding sleeve 232 when the movable support 23 is in the second position, so that the movable support 23 slides from the second position to the first position. Figure 24 and Figure 25 As shown, the support member 213 is provided with a limiting member 2132, one end of the elastic member 25 abuts against the limiting member 2132, and the other end of the elastic member 25 abuts against the sliding sleeve 232. During the process of the rider 22 rotating relative to the frame 21 from a forward use position to a rearward use position, due to the pushing action of the drive member 24, the movable bracket 23 moves along the support member 213 in the first direction F1 from... Figure 22 The first position shown is slid to Figure 23 In the second position shown, the sliding sleeve 232 compresses the elastic element 25. When the rider 22 is locked in the rearward use position by engaging the locking element 221 with the second locking part 2112 as described above, the elastic element 25 remains compressed. After the operator operates the locking element 221 to disengage from the second locking part 2112, the rider 22 can be rotated towards the forward use position. During the rotation of the rider 22 relative to the frame 21 from the rearward use position to the forward use position, under the action of the elastic restoring force of the elastic element 25, the elastic element 25 pushes against the sliding sleeve 232, causing the movable support 23 to move from... Figure 23 The second position shown slides to Figure 22 As shown. In this embodiment, the elastic element 25 is in the form of a helical spring. It can be understood that in other embodiments, the elastic element 25 may be other forms of elastic elements such as torsion springs, tension springs, compression springs, leaf springs, and irregularly shaped springs.

[0133] In this embodiment, the drive member 24 fixed to the rider 22 pushes the movable bracket 23 only when the rider 22 rotates relative to the frame 21 in a first rotation direction D1, causing the movable bracket 23 to slide from a first position to a second position relative to the frame 21 along the longitudinal direction of the child vehicle 2. When the rider 22 rotates relative to the frame 21 in a second rotation direction D2, opposite to the first rotation direction D1, the elastic member 25 pushes the movable bracket 23, causing the movable bracket 23 to slide back from the second position to the first position. Therefore, the operator can more easily and effortlessly change the direction of the rider 22.

[0134] Figure 26 and Figure 27 A child vehicle in forward and rearward modes, according to an embodiment of the third aspect of this application, is shown, with the seat removed for ease of explanation. The main difference between the child vehicle proposed in this aspect and the child vehicle proposed in the second aspect described above lies in the arrangement of the movable support and the manner in which the movable support is moved when the rider rotates. In the following description of this aspect, the same or similar aspects as those in the second aspect described above will not be repeated.

[0135] like Figure 26 and Figure 27 As shown, the child vehicle 3 includes a frame 31, a handlebar 32 pivotally mounted on the frame 31, and a movable support 33 slidably mounted on the frame 31. The frame 31 includes a front leg 311, a rear leg 312, a side armrest 313, and a center member 314. The upper ends of the front leg 311 and the rear leg 312 are pivotally connected to the front end of the side armrest 313. The upper end of the center member 314 is pivotally connected to the rear end of the side armrest 313, and the lower end of the center member 314 is pivotally connected to the rear leg 312. The structures of the front leg 311, rear leg 312, side armrest 313, and center member 314 are the same as those of the front leg 211, rear leg 212, side armrest 214, and center member 215 described in the second aspect above. Specific details of these components can be found in the second aspect described above.

[0136] Compared to the second aspect described above, in this aspect, the position of the movable support 33 is raised, and correspondingly, the seat mounted on the movable support 33 can be positioned at a higher height. Specifically, the child vehicle 3 also includes a first support 315 and a second support 316, with the second support 316 fixed above the first support 315. The movable support 33 is slidably disposed on the second support 316. The rider 32 is pivotally connected to the first support 315, and the rider 32 is configured such that when the rider 32 rotates relative to the first support 315, it drives the movable support 33 to slide along the second support 316. That is, the sliding path of the movable support 33 is above the pivot axis X1 of the rider 32's rotation about the frame 31.

[0137] Combined with reference Figure 28 and Figure 29The first support member 315 is similar to the support member 213 described in the second aspect above. One end of the first support member 315 is pivotally connected to the front foot 311, and the other end is pivotally connected to the neutral member 314. The first support member 315 includes a first support body 3151 extending substantially along the longitudinal direction of the child carrier 3. The height of the first support body 3151 in the frame 31 corresponds to the height of the support body 2131 of the support member 213 in the frame 21. In this embodiment, the first support member 315 has a first support portion 3152 and a second support portion 3153 extending vertically upward. The first support portion 3152 and the second support portion 3153 are respectively close to or located at the front end and rear end of the first support body 3151, that is, the first support portion 3152 and the second support portion 3153 are spaced apart in the longitudinal direction of the child carrier 3. The first support portion 3152 and the second support portion 3153 are used to support and fix the second support member 316, such that the second support member 316 extends substantially along the longitudinal direction of the child carrier 3. The second support member 316 can be installed on the first support portion 3152 and the second support portion 3153 using fasteners such as threaded fasteners, pin fasteners, or rivet fasteners, or it can be installed on the first support portion 3152 and the second support portion 3153 using permanent connection methods such as welding or bonding. In some other embodiments, the first support member 315 may not have the first support portion 3152 and the second support portion 3153; instead, the second support member 316 may have two vertically downward extending support portions, and the second support member 316 is fixed above the first support member 315 by installing these two support portions on the first support member 315. In other still embodiments, the first support member 315 and the second support member 316 may be integrally formed.

[0138] The child vehicle 3 also includes a drive assembly 34, configured such that when the rider 32 rotates relative to the first support member 315, the movable support 33 is driven by the rider 32 to slide along the second support member 316. Specifically, the drive assembly 34 includes a first drive member 341 and a second drive member 342. The first end of the first drive member 341 is fixedly connected to the rider 32, the first end of the second drive member 342 is hinged to the second end of the first drive member 341, and the second end of the second drive member 342 is pivotally connected to the movable support 33. Similar to the movable support 23 in the second aspect described above, the movable support 33 includes a movable support body 331 and a sliding sleeve 332, the sliding sleeve 332 being fixed to the movable support body 331 and slidably fitted onto the second support member 316. The second end of the second drive member 342 is pivotally connected to the movable support body 331.

[0139] The child vehicle 3 also includes a pivot shaft 321, through which the rider 32 is pivotally connected to a first support member 315. One end of the pivot shaft 321 is fixed to the rider 32, and the other end is fixed to a first drive member 341, such that the first drive member 341 rotates with the rotation of the rider 32. Specifically, the pivot shaft 321 passes through a neutral member 314, with a first end of the pivot shaft 321 extending from the neutral member 314 fixedly connected to the rider 32, and a second end of the pivot shaft 321 extending from the neutral member 314 passing through the first support member 315 and then fixedly connected to the first drive member 341. The second end of the pivot shaft 321 connected to the first drive member 341 can be configured to have a rectangular cross-section. Correspondingly, the first drive member 341 can have a fixing hole (not shown) that matches the cross-sectional shape of the second end of the first drive member 341. The second end of the pivot shaft 321 is adapted to be inserted into the fixing hole of the first drive member 341, and the first drive member 341 is fixedly connected to the second end of the pivot shaft 321 by, for example, an interference fit. When the rider 32 rotates, the first drive member 341 will rotate synchronously with the rider 32 due to the drive of the pivot shaft 321 fixedly connected between the rider 32 and the first drive member 341. It is understood that in some other embodiments, the cross-sectional shape of the second end of the pivot shaft 321 can be elliptical, rhomboid, hexagonal, or any other suitable shape. Furthermore, in other embodiments, the second end of the pivot shaft 321 can be fixedly connected to the first drive member 341 by welding, bonding, keying, pinning, riveting, or other methods.

[0140] In this embodiment, when the rider 32 rotates relative to the frame 31, since the first drive member 341 is relatively fixed to the rider 32, the first drive member 341 will rotate synchronously with the rider 32 to drive the movable support 33 to move relative to the frame 31 along the longitudinal direction of the child carrier 3. Specifically, since the first drive member 341 is hinged to the second drive member 342, during the rotation of the first drive member 341, the first drive member 341 will push the second drive member 342, causing the second drive member 342 to move. The second drive member 342, in turn, drives the movable support 33 to slide along the second support member 316. For example, when the rider 32 is in the forward use position, the movable support 33 is in... Figure 28 The first position is shown. During the rotation of rider 32 from the forward use position to the rearward use position, the first drive member 341 rotates with rider 32 and pushes the second drive member 342 to move. The second drive member 342 causes the movable bracket 33, pivotally connected to the second drive member 342, to slide along the second support member 316. Figure 29The second position shown indicates that the movable support 33 moves forward relative to the frame 31. Conversely, as the rider 32 rotates from the rearward use position to the forward use position, the first drive member 341 pulls the second drive member 342 to move it, and the second drive member 342 drives the movable support 33 along the second support member 316 from... Figure 28 The first position shown is slid to Figure 29 The second position shown is that the movable bracket 33 moves backward relative to the frame 31.

[0141] In this embodiment, by providing a second support member 316 above the first support member 315 pivotally connected to the rider 32, and slidably providing the movable bracket 33 on the second support member 316, the height of the movable bracket 33 in the frame 31 can be increased, thereby increasing the height of the seat (not shown) mounted on the movable bracket 33.

[0142] Figures 30 to 36 This illustration shows another embodiment of a child vehicle according to a third aspect of this application. The main difference between this embodiment and the above embodiments lies in the manner in which the movable support is moved when the rider rotates. In the following description of this embodiment, the same or similar aspects as those in the above embodiments will not be repeated.

[0143] Reference Figure 30 and Figure 31 Similar to the embodiments described above, the rotation of the rider 32 relative to the first support 315 drives the movable bracket 33 to move relative to the second support 316. For example, when the rider 32 moves from... Figure 30 Rotate to the forward use position shown Figure 31 In the rearward use position shown, the drive bracket 33 will slide forward along the second support 316, causing the drive bracket 33 to move forward relative to the frame 31. When the rider 32 moves from... Figure 31 Rotate to the position shown in the diagram. Figure 30 When in the forward-facing position, the drive bracket 33 will slide backward along the second support member 316, causing the drive bracket 33 to move backward relative to the frame 31.

[0144] In this embodiment, the child vehicle 3 includes a drive assembly 35, configured such that when the rider 32 rotates relative to the first support member 315, the drive assembly 35 drives the movable support 33 to slide along the second support member 316. The drive assembly 35 includes a first slider 351, which is connected to the movable support 33 and slidably disposed on the side armrest 313. When the rider 32 rotates relative to the first support member 315 to cause the first slider 351 to slide relative to the side armrest 313, the first slider 351 is adapted to drive the movable support 33 to slide along the second support member 316.

[0145] Combined with reference Figures 32 to 36 , among which, Figure 32 , Figure 33 , Figure 35 and Figure 36 For ease of explanation, a portion of the side armrest 313 is made transparent to reveal the components it previously concealed. The transparent portion of the side armrest 313 is shown in... Figure 32 and Figure 33 The middle part is represented by a dashed line.

[0146] like Figures 32 to 34 As shown, the first sliding member 351 can be, for example, in the form of a pin or a rod. A first groove 3131 is provided on the side armrest 313, through which the first sliding member 351 passes and is slidable. When the rider 32 rotates relative to the frame 31 to switch the child vehicle 3 from a forward-facing mode to a rearward-facing mode, or vice versa, the first sliding member 351 is adapted to slide from one end of the first groove 3131 to the other end. For example, when the rider 32 rotates from... Figure 30 Rotate to the forward use position shown Figure 31 When in the rearward use position shown, the first slider 351 slides from the rear end of the first groove 3131 along the first groove 3131 to the front end of the first groove 3131.

[0147] In this embodiment, the drive assembly 35 includes a first drive member 352, a second drive member 353, and a third drive member 354. The first drive member 352 is disposed on the rider 32 and configured to drive a first slider 351 to slide along a first groove 3131 relative to the side armrest 313 when the rider rotates relative to the first support member 315. The first slider 351 has a first end and a second end opposite to each other. The first end of the first slider 351 is connected to the first drive member 352, and the second end of the first slider 351 is pivotally connected to one end of the second drive member 353. The other end of the second drive member 353 is pivotally connected to one end of the third drive member 354, and the other end of the third drive member 354 is pivotally connected to a movable bracket 33, specifically, a movable bracket body 331 pivotally connected to the movable bracket 33.

[0148] The first drive component 352 includes a connecting portion 3521 and a drive portion 3522. The connecting portion 3521 is mounted on the rider 32, and the drive portion 3522 is fixed to the connecting portion 3521. The drive portion 3522 and the connecting portion 3521 can be integrally formed or manufactured separately and then fixed together by a permanent connection method such as welding or bonding. Furthermore, the connecting portion 3521 can be integrated with the engaging component 221 described above.

[0149] The drive unit 3522 has a sliding channel 3523, and the first end of the first slider 351 can slide within the sliding channel 3523. The sliding channel 3523 has a first pushing portion 3523a and a second pushing portion 3523b located at opposite ends of the sliding channel 3523. When the rider 32 rotates relative to the first support member 315 to move the child vehicle 3 from a forward-facing mode (e.g., ... Figure 30 (As shown) Switch to backward mode (as shown) Figure 31 When the first pushing part 3523a is adapted to push the first end of the first sliding member 351 (as shown), it causes the first sliding member 351 to slide relative to the side armrest 313, so that the first sliding member 351 drives the movable bracket 33 to slide forward along the second support member 316. When the rider 32 rotates relative to the frame 31 to move the child carrier from rear-facing mode (as shown), the first pushing part 3523a is adapted to push the first end of the first sliding member 351 to drive the first sliding member 351 to slide relative to the side armrest 313, so that the first sliding member 351 drives the movable bracket 33 to slide forward along the second support member 316. Figure 31 (As shown) Switch to forward mode (as shown) Figure 30 When (as shown), the second pushing part 3523b is adapted to push the first end of the first sliding member 351 to drive the first sliding member 351 to slide relative to the side armrest 313, so that the first sliding member 351 drives the movable bracket 33 to slide backward along the second support member 316.

[0150] The sliding channel 3523 is constructed such that, during the process of the rider 32 rotating from the forward use position to the rearward use position, after the rider 32 has rotated a predetermined angle relative to the frame 31, the first pushing part 3523a abuts against the first end of the first sliding member 351. Similarly, during the process of the rider 32 rotating from the rearward use position to the forward use position, after the rider 32 has rotated a predetermined angle relative to the frame 31, the second pushing part 3523b abuts against the first end of the first sliding member 351. Specifically, the sliding channel 3523 is arc-shaped, and the center of this arc is located at the pivot axis X1 of the rider 32's rotation around the frame 31 (see reference). Figure 30 and Figure 31 The first groove 3131 formed on the side armrest 313 is also arc-shaped, and the first groove 3131 and the sliding channel 3523 are on the same circumferential path.

[0151] One end of the second driving member 353 is pivotally connected to the second end of the first sliding member 351, and the other end of the second driving member 353 is pivotally connected to the movable bracket 33. Specifically, the other end of the second driving member 353 is provided with a second sliding groove 3531, which is in the form of an elongated slot. One end of the third driving member 354 is connected to the second sliding groove 3531 via a second sliding member 355. The second sliding member 355 can be, for example, in the form of a pin or a rod. One end of the second sliding member 355 is rotatably and slidably connected to the second sliding groove 3531. The other end of the second sliding member 355 is fixed to the third driving member 354. Through the sliding engagement between the second sliding member 355 and the second sliding groove 3531, during the movement of the second sliding member 353, the end of the second sliding member 355 embedded in the second sliding groove 3531 is rotatable relative to the second sliding groove 3531 and slidable along the second sliding groove 3531. The third driving member 354 moves in response to the movement of the second driving member 353 by abutting against the second sliding member 355 through the groove wall of the second sliding groove 3531, thereby driving the movable bracket 33 to slide along the second support member 316. The second sliding groove 3531 provides a space for the end of the third driving member 354 connected to the second driving member 353, allowing the other end of the second driving member 353 to drive the movable bracket 33 to slide along the second support member 316 via the third driving member 354 when one end of the second driving member 353 moves along the first sliding groove 3131.

[0152] The following is for reference only. Figure 35 and Figure 36 The process of moving the movable support 33 via the drive assembly 35 is described exemplarily in this embodiment. When the rider 32 is in the forward-facing position, the first slider 351 is located at the proximal end of the first slide groove 3131 of the side armrest 313, and the second pushing portion 3523b of the sliding channel 3523 abuts against the first end of the first slider 351. The proximal end of the first slide groove 3131 is the end of the first slide groove 3131 near the upper end of the neutral member 314, and the end of the first slide groove 3131 away from the upper end of the neutral member 314 is called the distal end. Along Figure 35During the process of rotating the rider 32 in the first rotation direction D1 to change the rider 32 from a forward-facing position to a rearward-facing position, the position of the first slider 351 initially remains unchanged. The drive unit 3522 slides over the first slider 351, causing the position of the first slider 351 in the sliding channel 3523 to change from abutting against the second push part 3523b to abutting against the first push part 3523a. After the first slider 351 abuts against the first push part 3523a, further rotation of the rider 32 in the first rotation direction D1 will cause the first slider 351 to slide along the first slide groove 3131 of the side armrest 313 from the proximal end to the distal end of the first slide groove 3131. After the first slider 351 reaches the distal end of the first slide groove 3131, the rider 32 can no longer rotate further in the first rotation direction D1. At this point, the conversion of the rider 32 from the forward-facing position to the rearward-facing position is completed. During the process of the first sliding member 351 sliding from the proximal end of the first slide groove 3131 to the distal end of the first slide groove 3131, the second driving member 353 moves along the first sliding member 351 along the first slide groove 3131. The second sliding member 355, which is slidably embedded in the second slide groove 3531, is pushed by the second driving member 353, thereby driving the third driving member 354 to move. The third driving member 354 then drives the movable bracket 33, which is pivotally connected to it, to slide forward along the second support member 316.

[0153] The process of rotating rider 32 from the rearward use position to the forward use position is the reverse of the above process. When rider 32 is in the rearward use position, the first slider 351 is located at the far end of the first slide groove 3131 of the side armrest 313, and the first push portion 3523a of the sliding channel 3523 abuts against the first end of the first slider 351. During the process of rotating rider 32 in the opposite direction of the first rotation direction D1, that is, the second rotation direction D2, to rotate rider 32 from the rearward use position to the forward use position, the position of the first slider 351 remains unchanged at first, and the drive unit 3522 slides over the first slider 351 so that the position of the first slider 351 in the sliding channel 3523 changes from abutting against the first push portion 3523a to abutting against the second push portion 3523b. After the first slider 351 abuts against the second pusher 3523b, further rotation of the rider 32 in the second rotation direction D2 will cause the first slider 351 to slide along the first groove 3131 of the side armrest 313 from the far end to the near end of the first groove 3131. After the first slider 351 reaches the near end of the first groove 3131, the rider 32 can no longer rotate further in the second rotation direction D2. At this point, the rider 32 has completed the transition from a rearward use position to a forward use position. During the process of the first sliding member 351 sliding from the far end of the first slide groove 3131 to the near end of the first slide groove 3131, the second driving member 353 moves along the first sliding member 351 along the first slide groove 3131. The second sliding member 355, which is slidably embedded in the second slide groove 3531, is pushed by the second driving member 353, thereby driving the third driving member 354 to move. The third driving member 354 then drives the movable bracket 33, which is pivotally connected to it, to slide backward along the second support member 316.

[0154] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0155] The above embodiments merely illustrate several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
