However, the present disclosure should not be construed as being limited to the embodiments set forth herein, but on the contrary, the present disclosure will cover all modifications, equivalents, and alternatives falling within the spirit and scope of the embodiments.

[0105] In the following description, a baby stroller is taken as an example, but it is understandable that the connecting seat locking mechanism and the frame folding locking mechanism according to the present invention can also be applied to other types of devices, such as a children's dining chair, a wheelchair, etc.

[0106] First refer to Figure 1 As shown, the Figure 11 is a schematic diagram showing a child riding device 1 according to the present application, the main structure of the child riding device 1 includes a frame 10 and wheels 20a, 20b assembled on the frame 10. The frame 10 of the child riding device 1 mainly includes a rider assembly 120, a front foot assembly 130, and a rear foot 140. In the embodiment shown in the figure, the rider assembly 120 includes a rider upper portion 122 and a rider lower portion 124 pivotally connected to each other, the front foot assembly 130 includes a front foot upper portion 132 and a front foot lower portion 134 pivotally connected to each other, the rider assembly 120, the front foot assembly 130, and the rear foot 140 are all pivotally connected to each other, the front wheel 20a is assembled to the front foot lower portion 134, and the rear wheel 20b is assembled to the rear foot 140. In the embodiment shown in the figure, the upper rider portion 122 and the lower rider portion 124, the upper front foot portion 132 and the lower front foot portion 134 are at least composed of rods respectively arranged on the left and right sides of the frame 10, and only one side is used as an example for description. Figure 1 In the figure, the infant carrier 2 is detachably mounted on the frame 10 through the connecting seat 30, so that the infant carrier 2 can be mounted on the frame 10 or removed from the frame 10 as needed. The infant carrier 2 shown in the figure can also be other devices, such as a child car seat.

[0107] Usually, the connecting seat used to detachably mount the infant carrier 2 on the frame 10 is also detachable. The connecting seat will be removed together with the infant carrier 2, and will be installed on the frame 10 together with the infant carrier 2 when the infant carrier 2 needs to be installed on the frame 10. Obviously, the connecting seat is very easy to be lost.

[0108] According to the present application, the connecting seat 30 is still fixed on the frame 10 after the infant carrier 2 is disassembled. Figure 2 As shown, the Figure 2 1 is a schematic diagram of a child carrier 1 according to the present application, wherein the infant carrier 2 is disassembled. According to the embodiment shown in the figure, the connecting seat 30 is pivotally connected to the third pivot point S3 where the front leg upper portion 132, the front leg lower portion 134 and the rear leg 140 of the frame 10 are pivotally connected. Even after the infant carrier 2 is disassembled, the connecting seat 30 according to the present application is still pivotally connected to the third pivot point S3, thereby avoiding the inconvenience caused by loss.

[0109] In addition, through the connection seat folding mechanism 50, the connection seat 30 still installed on the frame 10 after the infant carrier 2 is disassembled can also be folded as the frame 10 is folded, and can be unfolded as the frame 10 is unfolded. Specifically, Figure 3 and Figure 4 As shown, Figure 3 is a schematic diagram of a child carrying device 1 according to the present application, Figure 3When the frame 10 begins to fold, the upper rider portion 122 and the lower rider portion 124 of the frame 10 are pivoted and folded, and the upper front leg portion 132, the lower front leg portion 134 and the rear leg 140 of the frame 10 are pivoted and folded, thereby starting to fold the frame 10. At the same time, the connecting seat folding mechanism 50 drives the connecting seat 30 to start folding. Figure 4 As shown in the figure, as the frame 10 is completely folded, the connecting seat folding mechanism 50 also drives the connecting seat 30 to be in a completely folded state. The folded connecting seat 30 does not occupy additional space and does not cause the volume of the frame 10 in the folded state to increase.

[0110] The following will refer to Figure 5 The specific structure of the connection seat folding mechanism 50 according to the present application is described. Figure 5 1 is a schematic diagram showing the structure of the connecting seat folding mechanism 50 of the child carrying device 1 according to the present application. According to the embodiment shown in the figure, two connecting seats 30 are provided to provide stable and uniform support for the infant carrier 2. The two connecting seats 30 are respectively located on the left and right sides of the frame 10, and the pivot point of the connecting seat 30 and the frame 10 is located at the pivot point S4 (see Figure 6 ) above. Figure 5 , the pivot point between the connecting seat 30 and the frame 10 is located at the inner side of the third pivot point S3 where the front foot upper part 132, the front foot lower part 134 and the rear foot 140 are pivotally connected. For example, the pivot point between the connecting seat 30 and the frame 10 is coaxial with the pivot point S3. In other embodiments, the pivot point between the connecting seat 30 and the frame 10 is located at the front foot upper part 132 or the rider lower part 124. Accordingly, two connecting seat folding mechanisms 50 are also provided. In the following description, only one connecting seat folding mechanism 50 is used as an example for description, and accordingly, only one side of the pivot connection relationship is used as an example for description.

[0111] The connecting seat folding mechanism 50 includes a driving member 510 and a linkage member 520. The first end 522 of the linkage member 520 is pivotally connected to the front foot assembly 120 of the frame 10, and the second end 524 of the linkage member 520 is pivotally connected to the rider assembly 120 of the frame 10. Figure 5 In the illustrated embodiment, the first end 522 of the linkage member 520 is pivotally connected to the front foot lower portion 134, and the second end 524 of the linkage member 520 is pivotally connected to the rider lower portion 124. The first end 512 of the drive member 510 is pivotally connected to the connecting seat 30, and the second end 514 of the drive member 510 is pivotally connected to the linkage member 520.

[0112] According to other embodiments not shown, the second end 514 of the driving member 510 may also be pivotally connected to the rider assembly 120, for example, the second end 514 of the driving member 510 is pivotally connected to the rider upper portion 122, or pivotally connected to the rider lower portion 124. According to other embodiments not shown, the second end 514 of the driving member 510 may also be pivotally connected to the forefoot assembly 130, for example, the second end 514 of the driving member 510 is pivotally connected to the forefoot upper portion 132, or pivotally connected to the forefoot lower portion 134.

[0113] The folding and unfolding action of the frame 10 will drive the driving member 510 and the linkage member 520 of the connecting seat folding mechanism 50 to pivot, and then the connecting seat 30 can be folded along with the folding of the frame 10 and unfolded along with the unfolding of the frame 10 through the pivoting of the driving member 510 and the linkage member 520.

[0114] The following will take the second end 514 of the driving member 510 pivotally connected to the linkage member 520 as an example to illustrate the operation process of the connecting seat folding mechanism 50 .

[0115] See also Figure 6 ,Should Figure 6 It is a schematic diagram showing the structure of each pivot point of the child riding device 1 according to the present application. According to this embodiment, the upper part 122 of the rider and the upper part 132 of the front foot are pivoted at the first pivot point S1, the upper part 122 of the rider and the lower part 124 of the rider are pivoted at the second pivot point S2, and the upper part 132 of the front foot, the lower part 134 of the front foot and the rear foot 140 are pivoted at the third pivot point S3.

[0116] In addition, the lower part 134 of the front foot and the first end 522 of the linkage member 520 are pivoted at the fourth pivot point S4, the lower part 124 of the rider and the rear foot 140 are pivoted at the fifth pivot point S5, the lower part 124 of the rider and the second end 524 of the linkage member 520 are pivoted at the sixth pivot point S6, the second end 514 of the driving member 510 and the linkage member 520 are pivoted at the seventh pivot point S7, and the first end 512 of the driving member 510 and the connecting seat 30 are pivoted at the eighth pivot point S8.

[0117] When force is applied to the upper handlebar 122 or the lower front foot 134 to collapse the frame 10, Figure 4 and Figure 6 As shown, the rider upper portion 122 and the rider lower portion 124 are pivoted and folded close to each other through the second pivot point S2, the front foot upper portion 132 and the front foot lower portion 134 are pivoted and folded close to the rear foot 140 through the third pivot point S3, and the rider upper portion 122 and the front foot upper portion 132 are pivoted and folded close to each other through the first pivot point S1, and the rider lower portion 124 and the rear foot 140 are pivoted and folded close to each other through the fifth pivot point S5, so that the frame 10 is folded and folded to the reference position. Figure 4At the same time, since the rider's lower portion 124 is pivoted and folded close to the rear foot 140 through the fifth pivot point S5, the front foot lower portion 134 is pivoted and folded close to the rear foot 140 through the third pivot point S3, and the first end 522 of the linkage member 520 is pivotally connected to the front foot lower portion 134 through the fourth pivot point S4, and the second end 524 of the linkage member 520 is pivotally connected to the rider's lower portion 124 through the sixth pivot point S6, so that the rider's lower portion 124, The pivoting and retracting of the lower part 134 of the front foot will drive the linkage member 520 to pivot and retract close to the lower part 134 of the front foot. Since the second end 514 of the driving member 510 is pivotally connected to the linkage member 520 through the seventh pivot point S7, the pivoting of the linkage member 520 will drive the driving member 510 to pivot and retract. Since the first end 512 of the driving member 510 is pivotally connected to the connecting seat 30 through the eighth pivot point S8, the pivoting of the driving member 510 will drive the connecting seat 30 to move along the Figure 6 The connecting seat 30 is pivoted and folded in the direction of the arrow to be close to the lower part 134 of the front foot, without causing additional space to be occupied. In this embodiment, the connecting seat 30 is pivoted to the frame 10 at the lower end, and the upper end of the connecting seat 30 is provided with a clamping portion 38 for installing the infant carrier 2. In the unfolded state, the clamping portion 38 of the connecting seat 30 faces upward (such as Figure 2 ). Combined with reference Figure 4 In the folded state, the clamping portion 38 of the connecting seat 30 faces downward. In the folded state of the frame 10, the first pivot point S1, the third pivot point S3 and the fifth pivot point S5 are located above the second pivot point S2, and the third pivot point S3 and the fifth pivot point S5 are located in front of the first pivot point S1 and the second pivot point S2.

[0118] On the contrary, when the frame 10 is unfolded, as the upper portion 122 of the rider, the lower portion 124 of the rider, the upper portion 132 of the front foot, the lower portion 134 of the front foot, and the rear foot 140 are relatively spread apart from each other, the seventh pivot point S7 and the eighth pivot point S8 also drive the linkage member 520 and the driving member 510 to pivot and spread in the opposite direction, thereby driving the connecting seat 30 to pivot and spread upward to connect the infant carrier 2. In this way, even when the infant carrier 2 is removed, the connecting seat 30 is still installed on the frame 10, thereby preventing the occurrence of loss. At the same time, the connecting seat 30 can be folded with the folding of the frame 10 and unfolded with the unfolding of the frame 10 under the drive of the connecting seat folding mechanism 50, which is convenient to use and does not increase the volume of the frame 10 in the folded state.

[0119] The child riding device 1 according to the present application may also be provided with a frame folding locking mechanism 60 to lock the frame 10 in the folded state to prevent the frame from being randomly unfolded.

[0120] The following will refer to Figures 7 to 12 The frame folding and locking mechanism 60 according to the present application is described. Figures 7 to 12 Child carriers and Figures 1 to 6 The child carrying devices of the present invention are substantially the same, and only the differences are described below. Figure 7 1 is a schematic diagram showing a frame folding and locking mechanism 60 according to another embodiment of the present application. The frame folding and locking mechanism 60 mainly includes a fixing seat 610 and a folding and locking member 620. The fixing seat 610 can be arranged on one of the front foot assembly 130 and the rider assembly 120 of the frame 10. Correspondingly, the folding and locking member 620 can be arranged on the other of the front foot assembly 130 and the rider assembly 120 of the frame 10. When the frame 10 is in a fully folded state, the fixing seat 610 can be accommodated in the folding and locking member 620, thereby locking the folded state of the frame 10 to prevent the frame 10 from being accidentally unfolded.

When the frame 10 is folded, the upper portion 122 of the rider and the upper portion 132 of the front foot are close to each other. The fixing seat 610 may, for example, be in the form of a protrusion outward along the left-right direction of the frame 10. In addition to the upper portion 122 of the rider and the lower portion 124 of the rider pivotally connected to each other, the rider assembly 120 also includes a rider seat 121, and a tray 70 for accommodating items such as water cups is connected to the frame 10 through the rider seat 121. There are usually two rider seats 121, which are respectively disposed on the left and right sides of the frame 10. The following description will only take the rider seat 121 on one side as an example. Figure 7 As shown, the driver seat 121 is disposed on the upper portion 122 of the driver, and the folding and locking member 620 of the frame folding and locking mechanism 60 is disposed on the driver seat 121. Figure 8 As shown, the Figure 8 yes Figure 7The partial schematic diagram further shows the structure of the folding locking portion 620 of the frame folding locking mechanism 60 and the related structure of the driver's seat 121 according to another embodiment of the present application.

The limiting member 1212 can be in the form of a convex column, for example, the limiting member 1212 is a convex column integrally formed on the outer side of the driver's seat 121; correspondingly, a limiting groove 624 (at Fig. 9 As shown in FIG. 1 , the limit groove 624 is an arc-shaped slot around the pivot axis, and the limit member 1212 can be relatively movably accommodated in the limit groove 624. Fig. 9 As shown, the Fig. 9 The schematic diagram shows the specific structure of the folding locking member 620 of the frame folding locking mechanism 60 according to the present application. In addition to the above-mentioned limit groove 624, the folding locking member 620 also includes a clamping portion 621 and a pivoting portion 622. The clamping portion 621 and the pivoting portion 622 are respectively arranged at opposite ends of the folding locking member 620. The folding locking member 620 is installed in the above-mentioned installation recess 1211 via the pivoting portion 622. After the frame 10 is folded, the fixing portion 610 is accommodated in the clamping portion 621 of the folding locking member 620, thereby locking the folded state of the frame 10. The frame folding locking mechanism 60 according to the present application also includes an elastic member 630 ( Figure 8 In the embodiment shown in the figure, the elastic member 630 is a torsion spring, one end of which is fixed in the mounting recess 1211 of the driver's seat 121, and the other end of which abuts against the folding locking member 620, for example, abuts against the pivoting portion of the folding locking member 620, and the elastic member 630 is used to make the folding locking member 620 always face the direction of the fixing seat 610 ( Fig.10 The fixing base 610 is pivoted in the direction indicated by the arrow in the figure to accommodate the fixing base 610.

[0122] In addition, if Fig. 9 As shown in the figure, the folding locking member 620 is further provided with a pressure portion 623, which is provided at the outer periphery of the pivoting portion 622 and is tilted downward in the direction of pivoting toward the fixing seat 610, so that the operator can apply force in the direction of pivoting away from the fixing seat 610 through the pressure portion 623. For example, the operator can use his thumb to push the tilted pressure portion 623 to push the engaging portion 621 in the direction away from the fixing seat 610 ( Fig.10 ) to unlock the fixing seat 610 and the locking portion 621. Fig. 9 As shown in FIG. 6 , anti-slip ribs may also be provided on the inclined surface of the pressure-applying portion 623 .

[0123] In an embodiment not shown, the mounting recess 1211 and the limiting member 1212 may also be provided on the front foot upper portion 132, and the fixing seat 610 is provided on the rider seat 121. Accordingly, the folding locking member 620 is provided on the front foot upper portion 132, one end of the elastic member 630 is fixed to the front foot upper portion 132, and the other end of the elastic member 630 abuts against the folding locking member 620. Of course, the folding locking member 620 and the corresponding mounting recess 1211 and the limiting member 1212, as well as the fixing seat 610 may also be provided at other locations, as long as the positions of the fixing seat 610 and the folding locking member 620 correspond after folding so that the fixing seat 610 can be accommodated in the folding locking member 620.

[0124] The following uses the example of the fixing seat 610 being disposed on the upper portion 132 of the front leg and the folding and locking member being disposed on the upper portion 122 of the rider to illustrate the operation process of the frame folding and locking mechanism 60 according to the present application. Fig.10 , Fig.11 , Fig.12 As shown, Fig.10 The frame 10 is shown in a fully folded state. Fig.11 FIG. 1 shows a state where the frame 10 begins to unfold from the folded state. Fig.12 2 shows the frame 10 in a further unfolded state.

[0125] like Fig.10 As shown in the figure, in the fully folded state of the frame 10, the fixing seat 610 located on the upper part 132 of the front leg is accommodated in the engaging portion 621 of the folding locking member 620 located on the upper part 122 of the rider, and under the action of the elastic member 630, the engaging portion 621 always keeps pivoting in the direction of the fixing seat 610 (as shown by the arrow in the figure), so that the engaging portion 621 blocks the path of the fixing seat 610 moving with the unfolding of the frame 10, thereby preventing the frame 10 from unfolding. Therefore, the frame 10 in the folded state can be locked to prevent the frame 10 from accidentally unfolding.

[0126] like Fig.11 As shown in FIG. 1 , when the frame 10 needs to be unfolded, the thumb can be used to push against the pressure portion 623 (at Fig. 9 ) overcomes the elastic force of the torsion spring, forcing the engaging portion 621 to move along Fig.10 The frame 10 is pivoted in the reverse direction as indicated by the middle arrow, so that the engaging portion 621 gradually and completely leaves the fixing seat 610 , the folded and locked state of the frame 10 is released, and the operator can unfold the frame 10 at will. Fig.12 , the frame 10 is further unfolded, and the engaging portion 621 is now further away from the fixing seat 610 .

[0127] The following reference Fig.13A , 13B and Fig.14A , Fig. 14BAnother embodiment of the frame folding and locking mechanism 60 ′ according to the present application is described.

[0128] First refer to Fig.13A and Fig. 13B To explain, the Fig.13A and Fig. 13B 6 is a schematic diagram showing a child riding device according to another embodiment of the present application. The frame folding and locking mechanism 60' of the other embodiment includes a pad 620' and a groove 610'. For the convenience of illustration, Fig.13A A pad 620' located on one side is shown in FIG. 1 , and a groove 610' matching with the pad 620' is shown in FIG. Fig. 13B The matching pads 620' and grooves 610' may be provided on both sides of the child carrying device, or may be provided on only one side. According to the embodiment shown in the figure, the pads 620' of the frame folding and locking mechanism 60' are provided on the outer side of the upper part 122 of the rider, and the matching grooves 610' are provided on the inner side of the upper part 132 of the front foot. Of course, this is not limited to this. For example, the grooves 610' may be provided on the outer side of the upper part 122 of the rider, and the pads 620' may be provided on the inner side of the upper part 132 of the front foot.

[0129] Refer to Fig.14A , which is a schematic diagram of a child riding device according to another embodiment of the present application that is about to be in a fully folded state. As shown in the figure, as the frame is folded, the pad 620' gradually approaches the groove 610', and when the frame is fully folded, the pad 620' will cooperate with the groove 610' to lock the folded state of the frame to prevent the frame from loosening and disengaging. Specifically, referring to Fig. 14B As shown in FIG. 1 , this figure is a cross-sectional schematic diagram showing the specific structure of another embodiment of the frame folding and locking mechanism. The groove 610 ′ is provided with a first stopper 612 ′, and correspondingly, the pad 620 ′ is provided with a second stopper 622 ′. Specifically, according to Fig.14A and Fig. 14BIn the embodiment shown, the groove 610' is formed inwardly at a substantially central position of the forefoot upper portion 132, but the present invention is not limited thereto, and the groove 610' may also be formed at a position slightly above the forefoot upper portion 132. The groove 610' is, for example, an elongated groove, and its long side extends along the longitudinal direction of the forefoot upper portion 132. The side of the groove 610' close to the ground is defined as the inner side, and the other side opposite to the groove 610' is defined as the outer side. The first stopper 612' may be formed on a long side of the groove 610' close to the outer side, and the first stopper 612' and the forefoot upper portion 132 are smoothly transitioned so that the opposite second stopper 622' can slide over the first stopper 612'. The long side of the groove 610' close to the inner side may be flush with the surface of the front foot upper part 132 or may be concave relative to the surface of the front foot upper part 132; and the long side of the groove 610' close to the outer side, that is, the long side forming the first stopper 612' may be slightly protruding or flush with the surface of the front foot upper part 132. The pad 620' may be, for example, a fixed washer protruding outward from the outer side of the rider upper part 122, so that the side of the pad 620' close to the front foot upper part 132 when folded is the inner side and the side away from the front foot upper part 132 is the outer side, and the second stopper 622' is arranged on the outer side of the pad 620', and protrudes more from the outer side of the rider upper part 122 than the pad 620' as a whole, and smoothly transitions with the rest of the pad 620'. The second stopper 622' extends along the longitudinal direction of the upper rider portion 122, and when the frame is folded, the second stopper 622' passes over the first stopper 612' along a direction substantially perpendicular to the longitudinal direction of the upper rider portion 122, that is, the extending direction of the second stopper 622' is substantially perpendicular to the direction in which it passes over the first stopper 612'. The second stopper 622' is formed of, for example, an elastic body, and thus has a certain amount of deformation.

[0130] When the frame 10 is folded, the upper portion 122 of the rider is pivoted close to the upper portion 132 of the front foot. Accordingly, the pad 620' located at the upper portion 122 of the rider is gradually close to the groove 610' located at the upper portion 132 of the front foot. When the frame is fully folded, the second stop portion 622' of the pad 620' is moved along the groove 610'. Fig. 14B After the arrow direction in the figure passes over the first stopper 612' of the groove 610', it engages with the first stopper 612', thereby locking the folded state of the frame to prevent it from being loosened and disengaged. When the frame is fully folded, the longitudinal direction of the upper part 132 of the front leg is close to being perpendicular to the ground. Similarly, the extending direction of the first stopper 612' and the second stopper 622' is also close to being perpendicular to the ground. In addition, when the frame is fully folded, the frame folding locking mechanism 60' and the front and rear wheels are respectively on the front and rear sides of the frame, so that the locking effect can be better achieved.

[0131] When the frame needs to be unfolded, it can be forced along Fig. 14BApplying force in the direction opposite to the direction indicated by the middle arrow causes the second stop portion 622' to be disengaged from the first stop portion 612', so that the upper portion 122 of the rider's hand can be pivoted away from the upper portion 132 of the front foot, thereby unfolding the entire bicycle frame.

[0132] The frame folding and locking mechanism 60, 60' according to the present application is simple and compact in structure and does not occupy extra space. At the same time, it can ensure the folded state of the frame 10 and avoid accidental unfolding.

[0133] The child riding device 1 according to the present application may also be provided with a frame gripping mechanism 80, so that the user can grip the frame 10 when the frame 10 is fully folded, and then lift the frame 10 to facilitate carrying the frame 10, thereby preventing the user from cutting his hands when lifting the frame 10, increasing the comfort of use and keeping the appearance of the frame 10 simple.

[0134] Figures 15 to 18B A schematic diagram of a child carrier and / or its components according to another embodiment of the present application is shown, wherein Figures 15 to 18B The drive member 510 is omitted, however Figures 15 to 18B The connecting seat folding mechanism 50 of the child riding device of the embodiment shown in FIG. Figures 1 to 12 The connecting seat folding mechanism 50 of the child carrying device in the illustrated embodiment is the same, and includes a driving member 510 and a linkage member 520 .

[0135] exist Figures 15 to 18B In the embodiment shown in FIG, the rider assembly 120 further includes a rider grip 126, and the rider grip 126 and the rider upper portion 122 are pivotally connected at a ninth pivot point S9. Fig.15 In the fully extended state of the frame 10, the pivot point (ninth pivot point S9) between the rider handle 126 and the rider upper portion 122 is located above the first pivot point S1. When force is applied to the rider upper portion 122 or the front foot lower portion 134 to collapse the frame 10, the rider handle 126 and the rider upper portion 122 also pivot and collapse close to each other through the ninth pivot point S9. Fig.18B In the fully folded state of the frame 10, the first pivot point S1, the third pivot point S3, the fifth pivot point S5 and the ninth pivot point S9 are located above the second pivot point S2, and the third pivot point S3 and the fifth pivot point S5 are located in front of the first pivot point S1, the second pivot point S2 and the ninth pivot point S9.

[0136] In this embodiment, the rider assembly 120 further includes a rider seat 121, and the rider seat 121 is pivotally connected to a ninth pivot point S9, and a tray 70 for accommodating items such as water cups is connected to the frame 10 via the rider seat 121. When force is applied to the rider upper portion 122 or the front foot lower portion 134 to fold the frame 10, the tray 70 rotates as the rider handle 126 and the rider upper portion 122 pivotally fold toward each other, thereby forming an acute angle with the placement surface of the frame 10. Specifically, the tray 70 has a first side 701 (e.g., a top side) and a second side 702 (e.g., a bottom side) that are arranged opposite to each other, and a placement surface 71 of the tray 70 for accommodating items such as water cups is located on the first side 701. As shown in FIG. Fig.15 As shown in FIG. 1 , when the vehicle frame 10 is in a fully unfolded state, the storage surface 71 of the tray 70 is substantially opposite to the wheels 20a, 20b and is substantially parallel to the placement surface of the vehicle frame 10. Fig.18A and Fig.18B As shown in FIG, when the vehicle frame 10 is in the fully folded state, the receiving surface 71 of the tray 70 is also generally facing away from the folded wheels 20 a, 20 b, and forms an acute angle with the receiving surface of the vehicle frame 10 .

[0137] The frame gripping mechanism 80 is disposed on the second side 702 of the tray 70. Fig.17 As shown, the frame gripping mechanism 80 includes a main body 81 and a connecting portion 82. The main body 81 is used as a handle for the user to grip with fingers, and the main body 81 extends along the left-right direction of the frame 10. Both ends of the main body 81 are fixed to the second side 702 of the tray 70 via two connecting portions 82. The two connecting portions 82 are, for example, elastic fingers, respectively engaged with two fixing holes 72 correspondingly provided on the second side 702 of the tray 70.

[0138] When the frame 10 is fully extended, the front surface 703 of the tray 70 hides the frame gripping mechanism 80. Therefore, when the frame 10 is fully extended, the frame gripping mechanism 80 does not affect the appearance of the frame. When the frame 10 is fully folded, the tray 70 forms an acute angle with the placement surface of the frame 10, so that the frame gripping mechanism 80 is tilted downward and backward, thereby facilitating the user to lift the frame by gripping the frame gripping mechanism 80.

[0139] Since the features of the present invention can be embodied in a variety of forms without departing from the characteristics of the present invention, it should also be understood that the above-mentioned embodiments are not limited to any details described above, unless otherwise noted, but should be broadly interpreted as being within the scope defined by the appended claims.
