DETAILED DESCRIPTION OF THE INVENTION

[0048] 1 shows a perspective view of a child carrier 1000 according to a first embodiment of the present invention. The child carrier 1000 includes a body frame 900 and a stand plate 100 according to an embodiment of the present invention. In this embodiment of the present invention, the child carrier 1000 is specifically described using a stroller as an example, and the body frame 900 is accordingly described using a stroller as an example. Of course, in some alternative embodiments, the type of child carrier 1000 is not limited to the stroller shown in the figure; for example, the child carrier 1000 may be another product having a movable body frame, such as a child's tricycle.

[0049] Referring to FIG. 1 , the body frame 900 is basically symmetrical and foldable. In some embodiments, the body frame 900 includes, for example, two front leg frames 901, a footrest 902 connected between the two front leg frames 901, two rear leg frames 903, a cross tube 904 connected between the two rear leg frames 903, a handle frame, a seat 906, wheels 908, etc. The handle frame may include, but is not limited to, a lower handle 905 and an upper handle 907 pivotally connected to each other. The connection relationships of the components of the body frame 900 can be described in the related art and will not be repeated here.

[0050] Unless otherwise clearly specified and limited, the directional terms such as "front," "rear," "left," and "right" in each embodiment of the present invention are based on the "front," "rear," "left," and "right" directions when the child carrier is normally used, and in the drawings, arrows F and B are used to roughly indicate the "front" and "rear" directions, and arrows L and R are used to roughly indicate the "left" and "right" directions. These directional terms are used only to make the description of the embodiments of the present invention clearer, and are not used to unduly limit the scope of protection of the present invention.

[0051] 1, the stand plate 100 includes a bracket 1, a first support plate 21, a second support plate 22, a support wheel 24, etc. The front end of the bracket 1 is used to connect to the body frame 900 of the child carrier 1000. In some embodiments, a connection base 4 is provided at the front end of the bracket 1, and the bracket 1 is connected to the body frame 900 via the connection base 4. The connection base 4 is detachably or non-detachably connected to, for example, a rear leg frame 903 and / or a cross tube 904 of the body frame 900.

[0052] Continuing to refer to FIG. 1 , the first support plate 21 is provided adjacent to the rear end of the bracket 1 and is connected to the vehicle frame 900 via the bracket 1. Referring to the angled top perspective view and bottom perspective view of the stand plate 100 shown in FIGS. 2 and 3 , the first support plate 21 can include a top plate 211 and a bottom plate 212. The top plate 211 is used for a child to stand on, and the support wheels 24 are connected, for example, to attachment points 2110 on the top plate 211 and attachment points 2120 on the bottom plate 212 (see FIGS. 11 and 12 ). The top plate 211 and the bottom plate 212 can be locked with fasteners or can be fastened together using a buckle structure. Of course, the embodiment of the first support plate 21 is not limited to the above example. For example, in some alternative embodiments, the first support plate 21 can include only the top plate 211, without the bottom plate 212. At this time, the support wheel 24 may be connected to the top plate 211 or to the bracket 1 .

[0053] 4 to 6, the length of the bracket 1 in the front-to-rear direction is adjustable so that the position of the first support plate 21 can be adjusted. The second support plate 22 is movably connected to the first support plate 21 and is configured to be retracted or extended depending on the length of the bracket 1. Referring to FIG. 4, when the bracket 1 has a long length, the second support plate 22 is retractable. The extended second support plate 22 is supported by the bracket 1 and positioned in front of the first support plate 21. At this time, the second support plate 22 and the first support plate 21 form a first support base with a large area. Referring to FIG. 5, when the length of the bracket 1 needs to be shortened, the second support plate 22 is inverted and retracted. The retracted second support plate 22 overlaps the first support plate 21 to form a second support base with a small area. The retracted second support plate 22 does not interfere with the retraction of the bracket 1. Referring to FIG. 6, when the bracket 1 is shortened, the first support plate 21 and the second support plate 22, which are stacked together, move forward following the bracket 1.

[0054] As can be seen, when a child stands on the stand plate 100, the child is positioned within a protective space surrounded by the body frame 900 and the caregiver pushing the stroller, and the child's hands can grasp appropriate parts of the body frame 900 to ensure their balance while standing. As a child grows, their body shape changes accordingly. In the prior art, stand plates provide brackets and support plates whose front-to-back positions are fixed, allowing small children to stand close to the front of the support plate and grasp the body frame. Large children stand close to the rear of the support plate and grasp the body frame while maintaining an appropriate front-to-back distance from the body frame, ensuring a comfortable standing posture. When a small child stands in front of the support plate, the rear of the support plate is left unused, which not only prevents the caregiver from approaching the child from the front, but also limits the range of movement of the caregiver's feet.

[0055] In the stand plate 100 provided by the embodiment of the present invention, the length of the bracket 1 in the fore-aft direction is adjustable, and therefore the fore-aft position of the first support plate 21 is adjustable. When the stand plate 100 is used for a large child to stand, the bracket 1 can be moved backward to extend its length, and the position of the first support plate 21 moves backward as the bracket 1 is extended, conveniently allowing the second support plate 22 to unfold in front of the first support plate 21. After unfolding, the second support plate 22 and the first support plate 21 can provide a large-area first support base. Of course, the second support plate 22 can also be retracted in some cases, and after retraction, the second support plate 22 is stacked on the first support plate 21 to provide a small-area second support base. After the second support plate 22 is retracted, the bracket 1 is moved forward to shorten its length, and the positions of the first support plate 21 and second support plate 22 move forward as the bracket 1 is shortened. At this time, the stand plate 100 significantly reduces its own volume, thereby reducing the effect on the range of movement of the caregiver's feet.

[0056] In addition, in actual application, when the second support plate 22 and the first support plate 21 form a first support base or a second support base, the stand plate 100 provided by the embodiment of the present invention can be used for children to stand on or as a storage frame. In short, the stand plate 100 provided by the embodiment of the present invention can meet a wide variety of usage needs.

[0057] In some alternative embodiments, the second support plate 22 is not provided, and a child can be carried only by the first support plate 21. When the bracket 1 moves rearward to extend its length, the first support plate 21 moves rearward to accommodate a larger child standing. When the bracket 1 moves forward to shorten its length, the first support plate 21 moves forward to accommodate a smaller child standing, and the stand plate 100 has a small volume. In some alternative embodiments, a seat (not shown) for a child to sit on may be provided on the first support plate 21.

[0058] Referring to Figures 3 and 5, in some embodiments, burring points 221 may be provided on both the left and right sides of the second support plate 22, and the burring points 221 are engaged with the bracket 1 when the second support plate 22 is unfolded to prevent the second support plate 22 from wobbling in the left-right direction.

[0059] 4 to 6 , an exemplary connection configuration of the first support plate 21 and the second support plate 22 is shown. A pivot base 222 is provided at the rear end of the second support plate 22, and a pivot base 2111 is provided at the front end of the top plate 211 of the first support plate 21. The pivot base 222 and the pivot base 2111 are pivotally connected via a pivot 210, whereby the rear end of the second support plate 22 is pivotally connected to the front end of the first support plate 21. When the second support plate 22 needs to be stored, the second support plate 22 can be simply flipped around the pivot 210 backward (or toward the first support plate 21) until the second support plate 22 is stacked on the top plate 211 of the first support plate 21.

[0060] Referring to FIG. 6 , in some embodiments, the stand plate 100 may further include a holding mechanism 3. The holding mechanism 3 is used to maintain the relative position of the stacked first support plate 21 and second support plate 22, thereby preventing undesired movement between the second support plate 22 and the first support plate 21. The holding mechanism 3 may include, for example, a magnetically attractive member 31 provided on the first support plate 21 and a magnetically attractive member 32 provided on the second support plate 22. When the second support plate 22 is stacked on the first support plate 21, the magnetically attractive members 31 and 32 approach each other and are attracted to each other, thereby fixing the position of the second support plate 22 relative to the first support plate 21. One of the magnetically attractive members 31 and 32 may be a magnet, and the other may be made of a magnet or a material that can be attracted by a magnet. The magnetically attractive members 31 and 32 may be attached to the first support plate 21 and the second support plate 22 in any suitable manner. For example, in some embodiments, the magnetically attractive member 31 may be fitted to the first support plate 21 in the form of a molded overlay, and the magnetically attractive member 32 may be fitted to the second support plate 22 in the form of a molded overlay. In some alternative embodiments, the magnetically attractive member 31 may be attached between the top plate 211 and the bottom plate 212 of the first support plate 21. In some alternative embodiments, a housing 321 may be attached to the bottom surface 225 of the second support plate 22, the housing 321 having a chamber 3210 (see FIG. 11 ), and the magnetically attractive member 32 is housed in the chamber 3210 of the housing 321.

[0061] Of course, the embodiment of the retention mechanism 3 is not limited to the above example, and for example, in some alternative embodiments, the retention mechanism 3 may be a buckle provided on the first support plate 21 and / or the second support plate 22. When the second support plate 22 is placed on top of the first support plate 21, the first support plate 21 and the second support plate 22 may be fastened together by the buckle.

[0062] It should be noted that the connection configuration between the first support plate 21 and the second support plate 22 is not limited to the above example. For example, in some alternative embodiments, the second support plate 22 is slidably connected to the first support plate 21. More specifically, the second support plate 22 can be deployed or retracted by, for example, sliding back and forth along the top plate 211 of the first support plate 21. When the second support plate 22 slides forward, the area that the second support plate 22 overlaps with the first support plate 21 becomes smaller, and the second support plate 22 is deployed. When the second support plate 22 slides backward, the area that the second support plate 22 overlaps with the first support plate 21 becomes larger, and the second support plate 22 is retracted. In some other alternative embodiments, the second support plate 22 is, for example, detachably connected to the first support plate 21, and the second support plate 22 can be connected to the first support plate 21 and supported by the bracket 1 as needed, or can be disconnected from the first support plate 21 and disconnected from support by the bracket 1.

[0063] Referring to FIG. 7, a side view of another connection configuration between the first support plate 21 and the second support plate 22 is shown. The rear end of the second support plate 22 is connected to the front end of the first support plate 21, and the second support plate 22 has, for example, an expandable pleated structure. When the bracket 1 moves rearward to extend its length, the second support plate 22 can be extended forward and unfolded. When the bracket 1 needs to move forward to shorten its length, the second support plate 22 can be compressed rearward and stored. In some alternative embodiments, the second support plate 22 may adopt other configurations that allow it to expand and contract.

[0064] 6 and 8, in some embodiments, the bracket 1 is pivotally connected to the connection base 4 via a pivot 431, allowing the bracket 1 to flip forward relative to the connection base 4. Referring to FIG. 9, when the child carrier 1000 is in normal use and the use of the stand plate 100 is not required, the bracket 1 can be flipped forward to fold the stand plate 100 and position it in the space below the seat 906. The stand plate 100 minimizes the impact on the range of movement of the caregiver's feet. In some embodiments, the pivot 431 is located outside the horizontal tube 904 of the vehicle frame 900, i.e., outside the space below the seat 906 (see FIG. 1). As shown in FIG. 9, when the bracket 1 flips forward to the space below the seat 906, the horizontal tube 904 abuts against a member of the stand plate 100 (e.g., the second support plate 22), limiting the forward flip angle of the bracket 1. This prevents the forward-flipping stand plate 100 from contacting the ground.

[0065] 10 , in some embodiments, the body frame 900 of the child carrier 1000 is foldable. The bracket 1 is pivotally connected to the connection base 4, so that when the body frame 900 is folded, the second support plate 22 of the stand plate 100 is first accommodated, and then the bracket 1 can be shortened and inverted, without the need to remove the stand plate 100 from the body frame 900.

[0066] After the body frame 900 is folded, the stand plate 100 is inclined relative to the rear leg frames 903 and is stored between the two rear leg frames 903 (or the two front leg frames 901). Specifically, as shown in FIG. 10, the extension direction of the first support plate 21 (or the second support plate 22) intersects with the extension direction of at least one of the front leg frames 901, the rear leg frames 903, and the handle frame. In this embodiment, the extension direction of the first support plate 21 (or the second support plate 22) intersects with both of the front leg frames 901, the rear leg frames 903, and the handle frame.

[0067] As shown in FIG. 10 , the first support plate 21 (or the second support plate 22) passes through a plane defined by at least two rear leg frames 903. In this embodiment, the first support plate 21 (or the second support plate 22) passes through a plane defined by two front leg frames 901 and a plane defined by two rear leg frames 903. That is, the first support plate 21 (or the second support plate 22) extends from between the two rear leg frames 903 to between the two front leg frames 901. In this way, even if the stand plate 100 is not removed, the volume of the body frame 900 after folding does not increase significantly. Furthermore, the rotation of the first support plate 21 and the second support plate 22 is restricted by the front leg frames 901, the cross tubes 904, and the seat 906 and cannot be rotated arbitrarily, which is advantageous for convenient transportation of the body frame 900.

[0068] 11 and 12, the exploded views of the stand plate 100 show that the connection base 4 may include a main body 43, a first half hoop 41, and a second half hoop 42. The bracket 1 is pivotally connected to the main body 43 via a pivot 431, a first end of the first half hoop 41 is pivotally connected to a first end of the second half hoop 42 via a pivot 420 (FIG. 12), and a second end of the first half hoop 41 is detachably connected to a second end of the second half hoop 42. The integrally connected first half hoop 41 and second half hoop 42 are fastened to appropriate positions on a rear leg frame 903 of the vehicle body frame 900 to connect the stand plate 100 to the vehicle body frame 900.

[0069] 11 and 12 , in some embodiments, one of the first half hoop 41 and the second half hoop 42 may be integrally molded with the main body 43, thus reducing the assembly process. Of course, in some alternative embodiments, the first half hoop 41 and the second half hoop 42 may both be pivotally attached to the main body 43 by a pivot 420. The second end of the first half hoop 41 and the second half hoop 42 may be, for example, attached to each other. More specifically, the second end of the first half hoop 41 may be provided with a hook-shaped portion 411, and the second end of the second half hoop 42 may be provided with a hook-shaped portion 421, which is detachably attached to the hook-shaped portion 411. An operating portion 423 may be further provided at the second end of the second half hoop 42, and the operating portion 423 protrudes outward from the second half hoop 42, thereby making it convenient to operate the second half hoop 42. Of course, the detachable connection between the second end of the first half hoop 41 and the second end of the second half hoop 42 is not limited to the above example. For example, in some alternative embodiments, the second end of the first half hoop 41 and the second end of the second half hoop 42 may be detachably connected using a latch structure.

[0070] In some embodiments, the first and second half hoops 41, 42 connected together may be strapped to a cross tube 904, or the first and second half hoops 41, 42 connected together may be strapped to a rear leg frame 903 (see FIG. 1 ). To prevent the connecting base 4 from sliding downward along the rear leg frame 903, a recess 410 for accommodating the cross tube 904 is provided in the first half hoop 41 near the cross tube 904. When the first and second half hoops 41, 42 are strapped to the rear leg frame 903, the cross tube 904 restricts the connecting base 4 from sliding downward.

[0071] 13 and 14, an exemplary embodiment of the bracket 1 is shown. The bracket 1 includes two fitted sets of fixed sleeves 11 and telescopic sleeves 12. The two sets of fixed sleeves 11 and telescopic sleeves 12 are arranged approximately symmetrically in the left-right direction, and the following description will take one set of fixed sleeves 11 and telescopic sleeves 12 as an example. The fixed sleeve 11 is connected to the vehicle body frame 900 via the connection base 4, and the telescopic sleeve 12 is connected to the first support plate 21. The telescopic sleeve 12 is telescopic relative to the fixed sleeve 11, thereby changing the length of the bracket 1 and driving the first support plate 21 to move forward or backward.

[0072] 12, 13, and 14, in some embodiments, the fixing sleeve 11 is, for example, L-shaped and includes a longitudinal segment 1101 and a lateral segment 1102, with the lateral segment 1102 being located at the front end of the longitudinal segment 1101. The longitudinal segment 1101 and the lateral segment 1102 are, for example, integrally molded, and the longitudinal segment 1101 and the lateral segment 1102 are connected with a smooth transition. A plug 118 may be attached to the end of the lateral segment 1102, and the plug 118 has a mounting hole 1180 (see FIG. 12). The fixing sleeve 11 is pivotally attached to the main body 43 of the connection base 4 via a pivot 431 mounted in the mounting hole 1180. The telescopic sleeve 12 is fitted inside the fixing sleeve 11. More specifically, the telescopic sleeve 12 is, for example, L-shaped and includes a longitudinal segment 1201 and a lateral segment 1202. The lateral segment 1202 is located at the rear end of the longitudinal segment 1201, and the longitudinal segment 1201 and the lateral segment 1202 are connected by a smooth transition. The longitudinal segment 1201 of the telescopic sleeve 12 is slidably fitted within the longitudinal segment 1101 of the fixed sleeve 11, and a sleeve 19 for supporting the telescopic sleeve 12 may be provided at the end of the longitudinal segment 1101 (see FIG. 12 ). A passage 210 is formed between the top plate 211 and the bottom plate 212. The passage 210 includes a first segment 2101 that houses the longitudinal segment 1201 of the telescopic sleeve 12 and a second segment 2102 that houses the lateral segment 1202 of the telescopic sleeve 12. When the bracket 1 is extended or retracted, the longitudinal segment 1101 of the fixation sleeve 11 can move into or out of the first segment 2101 .

[0073] 13 and 14, the rear end of the vertical segment 1101 of the fixing sleeve 11 partially overlaps the front end of the first segment 2101, thus ensuring that the fixing sleeve 11 can slide smoothly relative to the first segment 2101. The engagement between the vertical segment 1101 of the fixing sleeve 11 and the first segment 2101 can further limit the relative position of the first support plate 21 and the bracket 1 in the left-right direction. The engagement between the horizontal segment 1202 of the telescopic sleeve 12 and the second segment 2102 can limit the position of the first support plate 21 and the bracket 1 in the front-to-rear direction.

[0074] Note that the embodiment of the bracket 1 is not limited to the above example, and may be any as long as it can drive the forward and backward movement of the first support plate 21 by its own extension and contraction. For example, in some alternative embodiments, the telescopic sleeve 12 can be fitted to the outside of the fixed sleeve 11, and when the bracket 1 is shortened, the fixed sleeve 11 enters the inside of the telescopic sleeve 12. At this time, the telescopic sleeve 12 directly fits into the first segment 2101, limiting the relative position of the first support plate 21 and the bracket 1 in the left-right direction. In some alternative embodiments, the configuration of the fixed sleeve 11 and the telescopic sleeve 12 themselves may have various variations and is not limited to the L-shaped configuration described above. In some alternative embodiments, the bracket 1 may include one or more pairs of fitted fixed sleeves 11 and telescopic sleeves 12, and one pair of fitted fixed sleeves 11 and telescopic sleeves 12 may be centrally disposed in the left-right direction, or multiple pairs of fitted fixed sleeves 11 and telescopic sleeves 12 may be symmetrically disposed in the left-right direction. In some alternative embodiments, the fixed sleeve 11 of the bracket 1 may be fitted in sequence with two or more telescopic sleeves 12, with the first support plate 21 being connected to the distal telescopic sleeve 12 of the plurality of telescopic sleeves 12. As will be understood, the distal telescopic sleeve 12 refers to the telescopic sleeve 12 that is furthest from the fixed sleeve 11 when each telescopic sleeve 12 is fully extended.

[0075] 11 to 13, the bracket 1 may further include a locking mechanism 13, which can be used to lock the position of the first support plate 21. In this embodiment, the locking mechanism 13 can lock the length of the bracket 1, thereby locking the position of the first support plate 21 and preventing undesired extension or shortening of the bracket 1.

[0076] More specifically, the locking mechanism 13 includes, for example, a first locking member 131 provided in the telescopic sleeve 12 and a first unlocking member 132 operably connected to the first locking member 131. As shown in FIG. 12 , a second positioning hole 120 is provided in a longitudinal segment 1201 of the telescopic sleeve 12, and the first locking member 131 extends from the second positioning hole 120. The second positioning hole 120 and the first locking member 131 are adjacent to the front end of the longitudinal segment 1201 of the telescopic sleeve 12. In this embodiment, at least two first positioning holes 110 are disposed in the longitudinal segment 1101 of the fixed sleeve 11, and the two first positioning holes 110 are spaced apart in the front-rear direction, and the first locking member 131 is slidably engaged with the first positioning holes 110. The first locking member 131 has a locked position and an unlocked position relative to the first positioning holes 110. In the locked position, the first locking member 131 is selectively inserted into one of the two first positioning holes 110 to fix the telescopic sleeve 12 in different telescopic positions. In the unlocked position, the first locking member 131 is removed from the first positioning hole 110 into which it was inserted, allowing the telescopic sleeve 12 to slide relative to the fixed sleeve 11. When it is necessary to adjust the telescopic position of the telescopic sleeve 12, an unlocking force is applied to the first unlocking member 132, which drives the first locking member 131 to move from the locked position to the unlocked position.

[0077] 15, when the first locking member 131 is inserted into the first positioning hole 110 near the rear end of the fixed sleeve 11, the telescopic sleeve 12 is locked in the extended position, and at this time, the second support plate 22 can be deployed to support the second support plate 22 on the fixed sleeve 11. Referring to FIG. 16, when the first locking member 131 is inserted into the first positioning hole 110 at the front end (i.e., away from the rear end of the fixed sleeve 11), the telescopic sleeve 12 is locked in the retracted position, and the second support plate 22 cannot be deployed.

[0078] Of course, the number of first positioning holes 110 of the fixed sleeve 11 is not limited to two. For example, in some alternative embodiments, at least one more first positioning hole 110 may be provided between the front end first positioning hole 110 and the rear end first positioning hole 110. By overlapping the second support plate 22 with the first support plate 21 so as not to interfere with the movement of the telescopic sleeve 12, the telescopic sleeve 12 can move back and forth together with the first support plate 21 and the second support plate 22, and the first locking member 131 can be inserted into any of the first positioning holes 110 as needed. As can be appreciated, the more first positioning holes 110 there are, the more telescopic positions the telescopic sleeve 12 can be locked in. Note that in some embodiments, only one first positioning hole 110 may be provided, thereby allowing the telescopic sleeve 12 to have one locked telescopic position.

[0079] 11 and 12 , exemplary embodiments of the operable connection between the first unlocking member 132 and the first locking member 131 are shown. Of course, the embodiment of the operable connection between the first unlocking member 132 and the first locking member 131 is not limited to the following examples. The locking mechanism 13 further includes a first driving member 133, a pulling member 134, a second driving member 135, and a first elastic return member 136. A first end of the pulling member 134 is connected to the first driving member 133, and a second end of the pulling member 134 is connected to the second driving member 135. The first driving member 133 is operably connected to the first unlocking member 132, and the second driving member 135 is operably connected to the first locking member 131. The first elastic return member 136 is used to drive the first locking member 131 to move to the locked position. Since the first unlocking member 132 can remotely drive the unlocking of the first locking member 131 using the first driving member 133, the pulling member 134 and the second driving member 135, the first unlocking member 132 can be mounted in a position away from the first locking member 131 and convenient for operation by a caregiver.

[0080] 11 and 12 , in some embodiments, the first unlocking member 132 is attached to the bottom plate 212 so as to be movable back and forth. More specifically, it is attached to the bottom of the rear end of the bottom plate 212, making it convenient to operate manually and less susceptible to accidental contact by children standing on the stand plate 100. The first unlocking member 132, for example, has an operating portion 1329 and an outwardly protruding stopper 1328. A recess 2129 may be provided on the bottom surface of the bottom plate 212, with the stopper 1328 of the first unlocking member 132 located inside the first support plate 21, and the operating portion 1329 of the first unlocking member 132 extending forward into the recess 2129 along the side wall of the recess 2129. When it is necessary to unlock the first locking member 131, the first unlocking member 132 can be pushed backward. Of course, in some alternative embodiments where the bottom plate 212 is not provided, the first unlocking member 132 can be attached to a suitable position on the top plate 211, for example.

[0081] 13, in some embodiments, the first driving member 133 is attached to a slide rail 2103 on the first support plate 21, for example. The slide rail 2103 extends in the left-right direction, allowing the first driving member 133 to slide left-right, with the direction of movement intersecting with the direction of movement of the first locking member 132. Referring to FIG. 15, the second driving member 135 is fitted within the longitudinal segment 1201 of the telescopic sleeve 12. The direction of movement of the second driving member 135 intersects with the direction of movement of the first locking member 131. The pulling member 134 may be a flexible rope (e.g., a wire rope), and the pulling member 134 is drilled into the telescopic sleeve 12 and connected between the first driving member 133 and the second driving member 135.

[0082] 11 and 12 , in some embodiments, the first unlocking member 132 is provided with a first inclined surface 1321. As shown in FIG. 12 , the first driving member 133 is provided with a first driving inclined surface 1331, and the first inclined surface 1321 abuts against the first driving inclined surface 1331. When the first unlocking member 132 receives an unlocking force and moves rearward, the first unlocking member 132 drives the first driving member 133 to move on the slide rail 2103 through cooperation of the first inclined surface 1321 and the first driving inclined surface 1331, and further pulls the second driving member 135 via the pulling member 134. As the second driving member 135 is pulled, it is driven to retract from the first positioning hole 110 into which the first locking member 131 was inserted.

[0083] Naturally, the configurations of the first unlocking member 132 and the first driving member 133 are not limited to the above example, and it is sufficient if the movement of the first unlocking member 132 can be converted into the movement of the first driving member 133 to drive the unlocking of the first locking member 131. For example, in some alternative embodiments, a slope may be provided on only one of the first unlocking member 132 and the first driving member 133.

[0084] 11 and 12 , in some embodiments, the second driving member 135 has an inclined hole 1350 having opposing second and third inclined surfaces 1352 and 1353. The first locking member 131 has a first shaft 1311. The first shaft 1311 may be integrally formed with the first locking member 131 or may be attached to the hole 1310 of the first locking member 131. The first shaft 1311 is drilled through the inclined hole 1350. When the second driving member 135 is driven by the pulling member 134 and moves, the second inclined surface 1352 abuts against and drives the first shaft 1311, thereby causing the first locking member 131 to retract from the first positioning hole 110 into which it was inserted. In other words, the second driving member 135 drives the first locking member 131 via the first shaft 1311.

[0085] 11 and 12 , in some embodiments, to ensure the movement of the first locking member 131, a fixed base 137 may be attached to the telescopic sleeve 12, and the fixed base 137 may have a first slide rail 1371 and a first slot 1372 communicating with the first slide rail 1371. The first locking member 131 is slidably fitted into the first slide rail 1371, and the first shaft 1311 is slidably fitted into the first slot 1372.

[0086] There are several embodiments of the first elastic return member 136. Referring to FIGS. 11 and 12 , in some embodiments, the first elastic return member 136 includes a spring sandwiched between the fixed base 137 and the second driving member 135. To conveniently fix the first elastic return member 136, the second driving member 135 may be provided with a recessed cavity 1355, and the fixed base 137 may be provided with a stopper 1375. The stopper 1375 fits into the recessed cavity 1355, and the first elastic return member 136 is sandwiched between the side wall of the recessed cavity 1355 and the stopper 1375. The side wall of the recessed cavity 1355 and the stopper 1375 are provided with positioning posts 1356 and 1376, respectively, for positioning the first elastic return member 136. The first elastic return member 136 is used to drive the second driving member 135 to return. When the second driving member 135 returns, the third inclined surface 1353 of the inclined hole 1350 comes into contact with and drives the first shaft 1311, thereby inserting the first locking member 131 into the first positioning hole 110. The pulling member 134 pulls the first driving member 133, causing the second driving member 135 to return, and the first inclined surface 1321 and the first driving inclined surface 1331 work together to cause the first lock releasing member 132 to also return.

[0087] Although the first elastic return member 136 has been described above as a spring that drives the return of the second driving member 135, in other embodiments, the number and installation positions of the first elastic return members 136 may be modified in various ways. For example, the first elastic return member 136 may include a spring that contacts the first locking member 131, a spring that contacts the first driving member 133, and a spring that contacts the first unlocking member 132.

[0088] The locking mechanism 13 may have various modifications and is not limited to the above examples. For example, in some embodiments, the bracket 1 includes a fixed sleeve 11 and at least two telescopic sleeves 12 that are fitted together in sequence, and the locking mechanism 13 for adjusting the length of the bracket 1 can be found, for example, in the locking mechanism of a pull-drive handle of a suitcase, and will not be described again here.

[0089] 17 is a perspective view of a child carrier 1000 provided by a second embodiment of the present invention. The child carrier 1000 includes a vehicle frame 900 and a stand plate 100 provided by this embodiment of the present invention, which is a modification of the stand plate 100 in the first embodiment described above. Where there is no contradiction, the description of the first embodiment may be referenced for the configuration of the stand plate 100 in this embodiment. The following description will mainly focus on the differences between the stand plate 100 in this embodiment and the stand plate 100 in the first embodiment.

[0090] 17, the connection base 4 has, for example, a locking hole 403, and the connection base 4 is attached to, for example, the rear leg frame 903 via the locking hole 403. The first support plate 21 has, for example, a large area, so that the second support plate 22 in the first embodiment can be omitted. When the bracket 1 extends and contracts forward and backward, the bracket 1 drives the first support plate 21 to move forward and backward as a whole, and the effective area for a child to stand on (the portion of the first support plate 21 located behind the horizontal tube 904) of the first support plate 21 changes accordingly, thereby adapting to the standing needs of children of different body types.

[0091] 18 and 19, an exemplary embodiment of the bracket 1 is shown. The bracket 1 includes a fixed sleeve 11 and a telescopic sleeve 12, the fixed sleeve 11 has a connection base 4 attached thereto, and the telescopic sleeve 12 is connected to a first support plate 21. The telescopic sleeve 12 is telescopic relative to the fixed sleeve 11, thereby changing the length of the bracket 1 and driving the first support plate 21 to move forward or backward to adjust the effective area of ​​the first support plate 21.

[0092] 19, the fixing sleeve 11 includes, for example, a horizontal segment (first horizontal segment) 1102 and at least one vertical segment (first vertical segment) 1101, and in this embodiment, two vertical segments 1101 are used as an example. The horizontal segment 1102 is located at the front end of the vertical segment 1101, and a plug 118 can be attached to the end of the horizontal segment 1102, and the plug 118 is pivotally attached to the connection base 4 via a pivot 431 (see FIG. 17). The two vertical segments 1101 are connected to the horizontal segment 1102 at a distance from each other, and the vertical segments 1101 and the horizontal segment 1102 are fixed together by, for example, welding, caulking, or a screw connection. The telescopic sleeve 12 includes a transverse segment (second transverse segment) 1202 and at least one longitudinal segment (second longitudinal segment) 1201. In this embodiment, two longitudinal segments 1201 are illustrated. The transverse segment 1202 is located at the rear end of the longitudinal segment 1201, and the two longitudinal segments 1201 are connected to the transverse segment 1202 with a gap between them. The transverse segment 1202 and the longitudinal segment 1201 are, for example, integrally molded. The two longitudinal segments 1101 of the fixed sleeve 11 correspond one-to-one to the two longitudinal segments 1201 of the telescopic sleeve 12, and the longitudinal segment 1201 of the telescopic sleeve 12 is slidably fitted within the longitudinal segment 1101 of the fixed sleeve 11. Of course, in some alternative embodiments, the longitudinal segment 1101 of the fixed sleeve 11 is slidably fitted within the longitudinal segment 1201 of the telescopic sleeve 12.

[0093] In some embodiments, the first support plate 21 maintains contact with the horizontal segment 1102 (in other words, the first support plate 21 maintains contact by hanging over the horizontal segment 1102 as the bracket 1 extends and retracts). Referring to FIG. 18 , when the bracket 1 is extended to its maximum length, the front end of the first support plate 21 is supported by the horizontal segment 1102. Of course, in other embodiments, the first support plate 21 may not be in contact with the horizontal segment 1102, but may be supported only by the vertical segment 1101 of the fixing sleeve 11. This allows the width of the first support plate 21 to be greater than the distance between the two vertical segments 1101.

[0094] 19, in this embodiment, the longitudinal segment 1101 of the fixing sleeve 11 has two fixing holes 110, which cooperate with the above-mentioned first locking member 131 to lock the position of the first support plate 21. Of course, in other embodiments, the longitudinal segment 1101 of the fixing sleeve 11 may have more fixing holes 110, thereby adjusting the position of the first support plate 21 according to the child's body shape and further adjusting the effective area for the child to stand.

[0095] 20 , when the length of the bracket 1 is shortened, the telescopic sleeve 12 drives the first support plate 21 to slide forward relative to the lateral segment 1102, thereby reducing the effective area of ​​the first support plate 21 for a child to stand on. Conversely, when the length of the bracket 1 is lengthened, the telescopic sleeve 12 drives the first support plate 21 to slide backward relative to the lateral segment 1102, thereby increasing the effective area of ​​the first support plate 21 for a child to stand on.

[0096] In this embodiment, the first support plate 21 includes, for example, a top plate 211 and a bottom plate (not shown), where the top plate 211 is used for a child to stand on, and the bottom plate is, for example, provided at the rear bottom of the top plate 211, roughly corresponding to the area of ​​the telescopic sleeve 12. In addition, in this embodiment, the locking mechanism 13 described in the first embodiment above may be provided, and the configuration of the locking mechanism 13 will not be repeated here.

[0097] 21, similar to the first embodiment described above, when the child carrier 1000 is in normal use and the use of the stand plate 100 is not required, the bracket 1 can be flipped forward, so that the stand plate 100 folds and is positioned in the space below the seat 906. In this way, it is possible to reduce the effect of the stand plate 100 on the range of movement of the caregiver's feet.

[0098] 22, it should be noted that after the bracket 1 of this embodiment is flipped forward, the first support plate 21 is not locked and can still rotate about the pivot 431. When the body frame 900 is folded, the front leg frame 901 and the lower handle 905 of the body frame 900 move toward the rear leg frame 903, and the first support plate 21 can rotate as the body frame 900 is folded, so it does not interfere with the folding of the body frame 900. As shown in FIG. 22, after the body frame 900 is folded, the rotation of the stand plate 100 is limited by the front leg frame 901, the cross tube 904, and the seat 906, and it cannot rotate arbitrarily, which is advantageous for the convenience of transporting the body frame 900.

[0099] After the body frame 900 is folded, the stand plate 100 of this embodiment is stored at an angle between the two rear leg frames 903 (or the two front leg frames 901). Specifically, as shown in Fig. 22, the extension direction of the first support plate 21 intersects with the extension direction of at least one of the front leg frame 901, the rear leg frame 903, and the handle frame (including the upper handle 907 and the lower handle 905). In this embodiment, the extension direction of the first support plate 21 intersects with the extension direction of both of the front leg frame 901, the rear leg frame 903, and the handle frame (including the upper handle 907 and the lower handle 905).

[0100] Furthermore, the first support plate 21 passes through a plane defined by at least two rear leg frames 903. In this embodiment, the first support plate 21 extends from between the two rear leg frames 903 to between the two front leg frames 901. This prevents a significant increase in the volume of the body frame 900 after folding, even if the stand plate 100 is not removed.

[0101] FIG. 23 is a perspective view of a child carrier 1000 according to a third embodiment of the present invention. The child carrier 1000 includes a body frame 900 and a stand plate 100 according to the third embodiment of the present invention. As described in the above embodiments, the child carrier 1000 is specifically described using a stroller as an example, and the body frame 900 is correspondingly described using a stroller as an example. Of course, in some alternative embodiments, the type of child carrier 1000 is not limited to the stroller shown in the figures. This embodiment shows another type of body frame 900 configuration, which includes two front leg frames 901, a footrest 902 connected between the two front leg frames 901, two bottom frames 909 connected to the two front leg frames 901, a cross tube 904 connected between the two bottom frames 909, an upper handle 905, and wheels 908.

[0102] 23, the stand plate 100 includes a bracket 1, a first support plate 21, a support wheel 24, a connection base 4, etc. The bracket 1 is connected to the horizontal pipe 904 via the connection base 4, the first support plate 21 is attached to the bracket 1, and the support wheel 24 is attached to the first support plate 21. The configurations of the bracket 1 and the first support plate 21 can be referred to above, and will not be described again here.

[0103] 24 to 26, this embodiment shows another exemplary configuration of the connection base 4. The connection base 4 includes a main body 43 and a second locking member 44. The main body 43 has an engaging groove 430 used for detachably connecting to the vehicle body frame 900. The second locking member 44 is movably attached to the main body 43, and has a closed position (FIG. 25) for closing the engaging groove 430 and an open position (FIG. 26) for opening the engaging groove 430. By switching the second locking member 44 between the closed position and the open position, the stand plate 100 can be conveniently attached to or detached from the horizontal tube 904.

[0104] 25 and 26 , in some embodiments, a second slide rail 4310 is provided on the main body 43 of the connection base 4, and the second locking member 44 is slidably fitted on the second slide rail 4310 to move between a closed position and an open position. A second elastic return member 46 is provided between the main body 43 and the second locking member 44, and the second elastic return member 46 is used to drive the second locking member 44 to move to the closed position.

[0105] 25 and 26 , in some embodiments, the second locking member 44 has a mounting groove 4420 and a second elongated hole 4410 communicating with the mounting groove 4420. The second elastic return member 46 includes a spring attached to the mounting groove 4420. A second shaft 45 is attached to the hole 4350 of the main body 43, and the second shaft 45 slides into the second elongated hole 4410 and is located within the mounting groove 4420. The second shaft 45 abuts against the second elastic return member 46. Referring to FIG. 26 , when the second locking member 44 receives a forward pulling force and opens the engaging groove 430, the second elastic return member 46 is compressed. When the forward pulling force received by the second locking member 44 is released, the second elastic return member 46 drives the second locking member 44 to move and close the engaging groove 430. The second locking member 44 may be provided with an outwardly protruding operating portion 445, and the main body 43 may be provided with a recess 435. When the second locking member 44 is in the closed position, the operating portion 445 is engaged with the recess 435. In some embodiments, an end cap (see end cap 446 in FIG. 31 ) may be attached to the opening of the attachment groove 4420.

[0106] Referring to the perspective view of the child carrier 1000 shown in FIG. 27, the bracket 1 is pivotally connected to the connection base 4 via a pivot 431, which is located outside the horizontal tube 904, and the forward tilt angle of the bracket 1 is limited by the horizontal tube 904. Unlike the first embodiment, referring to FIGS. 28 and 29, in this embodiment, a rotation control mechanism 5 is provided between the bracket 1 and the connection base 4, and the rotation control mechanism 5 is used to control the rotation position of the bracket 1. Referring to FIG. 26, when the stand plate 100 is not in use, the stand plate 100 can be rotated forward to an appropriate position, and the rotation control mechanism 5 can hold the stand plate 100 in the rotated position.

[0107] 28 to 31 , an exemplary embodiment of the rotation control mechanism 5 is shown, which is used to control the rotation of the bracket 1 in one direction around the pivot 431. The rotation in one direction limits the stand plate 100 so that it can flip forward but not backward. More specifically, the rotation control mechanism 5 includes a lock gear 51, and a plurality of third teeth 513 are provided on the peripheral wall of the lock gear 51. The connection base 4 has a first storage cavity 40, and the first teeth 401 are provided on the cavity wall of the first storage cavity 40. The bracket 1 has a second storage cavity 10, and the second teeth 101 are provided on the cavity wall of the second storage cavity 10. The lock gear 51 is located in the first storage cavity 40 and the second storage cavity 10, and is capable of moving axially between the bracket 1 and the connection base 4.

[0108] The lock gear 51 has a locked position and an unlocked position. Referring to FIG. 30, when the lock gear 51 is in the locked position, the third tooth portion 513 of the lock gear 51 maintains engagement with the first tooth portion 401 of the connection base 4 and the second tooth portion 101 of the bracket 1. The third tooth portion 513 is provided with an oblique engagement surface 511 (see FIG. 28), which abuts against the second tooth portion 101. When the first support plate 21 is turned upside down, the oblique engagement surface 511 allows the bracket 1 to rotate in one direction, that is, forward, but does not allow the bracket 1 to rotate backward. Referring to Figure 31, when the lock gear 51 is in the unlocked position, the lock gear 51 moves axially, and its third tooth portion 513 completely disengages from either the first tooth portion 401 or the second tooth portion 101, allowing the bracket 1 to rotate in both directions (forward and backward rotation).

[0109] In the above embodiment, the oblique meshing surface 511 is provided on the lock gear 51, and the second toothed portion 101 is also provided with an oblique meshing surface 1011 that mates with the oblique meshing surface 511. As can be appreciated, in other embodiments, the first toothed portion 401 may be provided with an oblique meshing surface.

[0110] 28 to 31 , the rotation control mechanism 5 may further include a second unlocking member 52 and a third elastic returning member 53. The third elastic returning member 53 is used to drive the lock gear 51 to move from the unlocked position to the locked position, and the second unlocking member 52 is used to drive the lock gear 51 to move from the locked position to the unlocked position. Referring to FIGS. 30 and 31 , the second unlocking member 52 and the third elastic returning member 53 are located on both sides of the lock gear 51. The second unlocking member 52 is, for example, a button, and has an elastic arm 521 that abuts against the lock gear 51. When an external force is applied to press the second unlocking member 52, the elastic arm 521 of the second unlocking member 52 drives the lock gear 51 to the unlocked position, and the third elastic returning member 53 is compressed. When the external force is released, the third elastic returning member 53 drives the lock gear 51 to the locked position, and the second unlocking member 52 returns to its original position.

[0111] 32 to 34 show perspective views of a stand plate 100 provided in one embodiment of the present invention, which is a modification of the stand plate 100 in the third embodiment described above. Where no contradiction exists, the description of the third embodiment may be referred to for the configuration of the stand plate 100 in this embodiment. Below, differences between the stand plate 100 in this embodiment and the stand plate 100 in the third embodiment will be mainly described.

[0112] 32 and 33, this embodiment shows an end cap 446 attached to the mouth of the mounting groove 4420.

[0113] 35 and 36, the connection base 4 includes a pivot base 4361 and a pivot base 4362, and the end 16 of the bracket 1 is sandwiched between the pivot bases 4361 and 4362. The bracket 1 is pivotally connected to the pivot bases 4361 and 4362 via a pivot shaft 431. The pivot base 4362 has a first storage cavity 40, and a first tooth portion 401 is provided on the cavity wall of the first storage cavity 40. The pivot base 4361 has a hole 4360, and a decorative cover 437 is provided in the hole 4360, and the pivot shaft 431 passes through the decorative cover 437. The bracket 1 has a second storage cavity 10, and a second tooth portion 101 is provided on the cavity wall of the second storage cavity 10. The lock gear 51 is located in the first receiving cavity 40 and the second receiving cavity 10 and is movable in the axial direction of the pivot 431 between the bracket 1 and the connection base 4 .

[0114] The lock gear 51 has a locked position and an unlocked position. When the lock gear 51 is in the locked position, the third tooth portion 513 of the lock gear 51 maintains engagement with the first tooth portion 401 of the connection base 4 and the second tooth portion 101 of the bracket 1. Referring to FIG. 35 , the third tooth portion 513 is provided with a first diagonal meshing surface 516 and a second diagonal meshing surface 517, which mesh with different teeth of the first tooth portion 401. When the first support plate 21 is flipped up or down, the first support plate 21 drives the bracket 1 to rotate, and the bracket 1 applies a circumferential force to the lock gear 51. Due to the action of the first diagonal meshing surface 516 and the second diagonal meshing surface 517, the lock gear 51 moves axially as the bracket 1 rotates until it moves to the unlocked position where it does not engage with the first tooth portion 401. That is, the first diagonal meshing surface 516 and the second diagonal meshing surface 517 allow the lock gear 51 to move axially when subjected to a circumferential force, thereby causing the lock gear 51 to move to an unlocked position and further allowing the bracket 1 to rotate in both directions, thereby adjusting the positions of the bracket 1 and the stand plate 100.

[0115] The rotation control mechanism 5 may further include a fourth elastic return member 54, which may be, for example, a spring, used to drive the lock gear 51 to return from the unlocked position to the locked position. When the bracket 1 rotates to the appropriate position, the first support plate 21 is no longer reversed, and the fourth elastic return member 54 drives the lock gear 51 to move to the locked position, thereby locking the rotation position of the bracket 1.

[0116] In the above-described embodiment, the first oblique meshing surface 516 and the second oblique meshing surface 517 are provided on the lock gear 51, but it can be understood that in other embodiments, the first oblique meshing surface 516 and the second oblique meshing surface 517 may be provided on the first toothed portion 401 or the second toothed portion 101.

[0117] As can be understood, the embodiment of the rotation control mechanism 5 is not limited to the above example, and it is sufficient if it allows the bracket 1 to rotate as needed, or can lock the rotation position of the bracket 1.

[0118] The technical features of the above embodiments can be combined in any way, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but as long as there is no contradiction in the combination of these technical features, it should be considered to be within the scope described in this specification. The above examples merely illustrate some embodiments of the present invention, and the descriptions are relatively specific and detailed, but this should not be understood as limiting the scope of the claims. It should be noted that those skilled in the art can make some modifications and improvements without departing from the concept of the present invention, and all of these are within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be governed by the appended claims.
