[0019] Exemplary embodiments are described in detail below with reference to the accompanying drawings. Although the present disclosure is open to various modifications and alternative forms, specific embodiments are shown by way of example in the drawings. However, the present disclosure should not be interpreted as being limited to the embodiments set forth herein; on the contrary, the present disclosure will cover all modifications, equivalents, and alternatives that fall within the spirit and scope of the embodiments.

[0020] For the sake of simplicity, the following detailed description of the present disclosure relates mainly to a child safety seat, but the footrest device according to the present disclosure can also be applied to other child carriers.

[0021] The child carrier 1 comprises a seat body 10, a base 20, and a support mechanism 30. The seat body 10 is connected to the base 20, and the support mechanism 30 is arranged on the base 20. The support mechanism 30 includes a support tube 100 and a support foot 200, which is arranged on the underside of the support tube 100. As shown in Fig. As shown in Figure 1, the child carrier 1 of an exemplary child safety seat includes a seat body 10 for carrying a child to provide safety protection during vehicle travel; the base 20 is arranged under the seat body 10, and the base 20 is mounted on a vehicle seat; to prevent the safety seat from tipping over in the event of an accidental collision, and to reduce the forward displacement of the safety seat during an accidental collision, the support mechanism 30 is further pivotably connected under the base 20, and the support mechanism 30 extends from a front end of the safety carrier 1 to be attached to the floor of the vehicle by the support leg 200 to provide more stable support for the child carrier 1.To solve the problem that children cannot place their feet during the ride, a footrest device 300 is connected to the support mechanism 30 according to the present disclosure.

[0022] In one embodiment, the footrest device 300 is arranged on the support tube 100 of the support mechanism 30. In one embodiment, as in Fig. As shown in Figure 1, the footrest device 300 is pushed onto the support tube 100 of the support mechanism 30.

[0023] In one embodiment, the footrest device 300 can slide up and down along the support tube 100 of the support mechanism 30 to adjust its position, thus facilitating its use by children of different ages and sizes. In another embodiment, the footrest device 300 is able to adjust its height position continuously (without limitations) along the support tube 100. That is, the footrest device 300 can be set to any desired height position along the support tube 100.

[0024] With reference to Fig. 2 and Fig. 3. The support mechanism 30, together with the footrest device 300 mounted on it, can be folded under the base to save space and facilitate storage when not in use. Furthermore, the support tube 100 comprises a first support tube 110 and a second support tube 120, which are nested within each other. For example, the first support tube 110 and the second support tube 120 are nested within each other by means of an engagement seat 130. The first support tube 110 can be accommodated within the second support tube 120, or the second support tube 120 can be accommodated within the first support tube 110. In this way, the length of the support tube 100 can be further shortened during storage, which facilitates storage.According to one embodiment (not shown), a storage groove can be provided on the underside of the base 20 to accommodate the stored support tube 100 and part of the footrest device 300, thereby reducing the overall height of the child carrier after storage. In the [reference to be added] Fig. In the embodiment shown in Figure 3, the first end 111 of the first support tube 110 is pivotably connected to the base 20, the second end of the first support tube 110 is pushed onto the first end 121 of the second support tube 120 through the engagement seat 130, and the second end 122 of the second support tube 120 is connected to the support foot 200. However, the present disclosure is not limited to this, and the support tube 100 can also be an adjustable support tube with three sections. The foot support device 300 can be pushed onto the upper part of the first support tube 110 or onto the lower part of the second support tube 120.

[0025] Next, the specific structure of the footrest device 300 will be described with reference to Fig. 4, Fig. 5 and Fig. 6 further described.

[0026] The footrest device 300 according to the embodiment comprises a pedal section 310 and a connecting element 320. The pedal section 310 allows the passenger to position their left and right feet. The pedal section 310 is connected to the support tube 100 by the connecting element 320. For example, the pedal section 310 can be slidably arranged on the support tube 100 by means of the connecting element 320 in order to adjust the height of the pedal section 310.

[0027] In one embodiment, with reference to Fig. 3, the connecting element 320 surrounds the support tube 100, for example, surrounds an outer circumference of the first support tube 110. In one embodiment, in particular, as in Fig. As shown in Figure 4, the pedal section 310 can comprise left and right parts so that the passenger can place their left and right feet, respectively. The pedal section 310 can surround the left, front, and right sides of the connecting element 320. A portion of the pedal section 310 facing the front of the child carrier can be wider than a portion facing the rear of the child carrier, thus providing sufficient space for the passenger's feet to rest.

[0028] In one embodiment as in Fig. As shown in Figure 5, a footrest covering 315 is arranged on an upper surface of the pedal section 310, and a decorative covering 316 is arranged over the footrest covering 315. The decorative covering 316 is typically made of a flexible material and exhibits some flexibility and anti-slip properties. A groove corresponding to the shapes of the footrest covering 315 and the decorative covering 316 can also be formed on the upper surface of the pedal section 310 to facilitate the arrangement of the footrest covering 315 and the decorative covering 316.

[0029] In one embodiment, the pedal section 310 further comprises a movable plate 312 and a stationary plate 314, which are pivotably connected to each other. Referring to the above, Fig. In the embodiment shown in Figure 6, the movable plate 312 is provided with a tab of the movable plate 3122, and the stationary plate 314 is provided with a tab of the stationary plate 3142. A pivot hole 3142a is formed in the tab of the stationary plate 3142. The pivot shaft 3122a, which runs through the tab of the movable plate 3122, is inserted into the pivot hole 3142a of the tab of the stationary plate 3142 in order to pivotably connect the stationary plate 314 and the movable plate 312, so that the movable plate 312 can pivot about a first pivot axis L1 (in Fig. 7 shown) is pivotable relative to the stationary plate 314.

[0030] In one embodiment, the pedal section 310 can have a folded position and a working position. In the folded position, the pedal section 310 is parallel to the support tube 100 of the support mechanism 30.

[0031] In one embodiment, the pedal section 310 is in the operating position perpendicular to the support tube 100 of the support mechanism 30 in order to realize the footrest function of the footrest mechanism.

[0032] In one embodiment, in the folded position, a normal direction of a plane in which the plate body of the pedal section 312 is located is perpendicular to a longitudinal direction of the support tube 100 of the support mechanism 30.

[0033] In one embodiment, in the operating position, the normal direction of the plane in which the plate body of the pedal section 310 is located is parallel to the longitudinal direction of the support tube 100 of the support mechanism 30.

[0034] In one embodiment, the footrest section 310 can be pivotably arranged about the connecting element 320 to have the folded position and the operating position.

[0035] Next, as in Fig. Figure 8 shows a folded state of the footrest device 300 of the child carrier 1 according to the present disclosure in Fig. 8 illustrates. Regarding a in Fig. In the arrangement shown in Figure 8, a right side of the connecting element 320 is connected to the stationary plate 314 of the pedal section 310 by a first pivot seat 340, and a left side of the connecting element 320 is connected to the stationary plate 314 of the pedal section 310 by a second pivot seat 350. A central connecting line between the first pivot seat 340 and the second pivot seat 350 defines a second pivot axis L2, which is perpendicular to the previously mentioned first pivot axis L1. With such an arrangement, the movable plates 312 on both sides of the pedal section 310 are pivotable and foldable about the first pivot axis L1 relative to the stationary plate 314, as shown in Figure 8. Fig. Figure 7 shows that this can reduce the overall width of the footrest device 300 to meet the requirements of some regulations that the width of the support mechanism must be less than 200 mm. Furthermore, as shown in Fig. As shown in Figure 8, the stationary plate 314 of the pedal section 310 can also pivot about the second pivot axis L2 relative to the connecting element 320 in order to bring the pedal section 310 into a stowed position. Thus, when the support mechanism 30 is completely folded in, as shown in Figure 8, the stationary plate 314 of the pedal section 310 can also pivot about the second pivot axis L2 relative to the connecting element 320 in order to bring the pedal section 310 into a stowed position. Fig. As shown in Figure 2, the pedal section 310 in the stowed position will not obstruct the swiveling of the support tube 100, which makes the folding of the support mechanism 30 smoother and reduces the height of the entire child carrier 1 after folding.

[0036] The footrest device 300 according to one embodiment further comprises a locking element 330 for locking the footrest section 310 in the operating position.

[0037] Next, the specific structures of the connecting element 320 and the locking element 330 according to an embodiment of the present disclosure will be described with reference to Fig. Figure 9 describes a schematic view of the connecting element 320 and the locking element 330 of the child carrier 1 according to the present disclosure. According to the Fig. In the embodiment shown in Figure 9, the connecting element 320 comprises a first connecting seat 321 and a second connecting seat 322, which are connected to each other. The structures of the first connecting seat 321 and the second connecting seat 322 are arranged symmetrically. Therefore, for the sake of brevity, only the specific structure of the first connecting seat 321 or the second connecting seat 322 will be described below as an example. The first connecting seat 321 comprises a locking structure 3211, and the second connecting seat 322 also comprises a locking structure 3221. Both the locking structure 3211 of the first connecting seat 321 and the locking structure 3221 of the second connecting seat 322 are generally approximately C-shaped, so that they form an elliptical or circular shape after being connected to conform to the outer circumferential shape of the support tube 100.The locking structure 3211 of the first connecting seat 321 and the locking structure 3221 of the second connecting seat 322 can be permanently or detachably connected to each other by a closure 3211a to surround the support tube 100. In the in . Fig. In the embodiment shown in Figure 9, the fastener 3211a is a pin connection structure such that the locking structure 3211 of the first connection seat 321 and the locking structure 3221 of the second connection seat 322 are not detachable after they have been connected. However, the present disclosure is not limited to this. The fastener 3211a can also be a matching screw and screw hole to achieve a detachable connection, or the locking structure 3211 of the first connection seat 321 and the locking structure 3221 of the second connection seat 322 can be designed as an integral structure.

[0038] According to one embodiment, the first connecting seat 321 further comprises a pivot structure 3212. The pivot structure 3212 is pivotably connected to the aforementioned first pivot seat 340 and, through the first pivot seat 340, to the pedal section 310. A rotary slot 3212a and a connecting hole 3212b are arranged on an end face of the pivot structure 3212 opposite the pedal section 310. According to the embodiment in Fig. In the embodiment shown in Figure 9, two rotary slots 3212a are provided, and both rotary slots 3212a are arcuate elongated slots and are arranged symmetrically with respect to the connecting hole 3212b.

[0039] Similarly, the second connecting seat 322 further comprises a pivot structure 3222. The pivot structure 3222 is pivotally connected to the aforementioned second pivot seat 350 and, through the second pivot seat 350, to the pedal section 310. A rotary slot 3222a and a connecting hole 3222b are arranged on the end face of the pivot structure 3222 opposite the pedal section 310. According to the Fig. In the embodiment shown in Figure 9, two rotary slots 3222a are provided, and both rotary slots 3222a are arcuate elongated slots and are arranged symmetrically with respect to the connecting hole 3222b.

[0040] With regard to the footrest device 300 according to one embodiment, the connecting element 320 can comprise only the first connecting seat 321. The first connecting seat 321 comprises a locking structure 3211, and the locking structure 3211 of the first connecting seat 321 is generally approximately C-shaped to conform to the outer circumferential shape of the support tube 100.

[0041] The locking element 330 according to the present disclosure is arranged on the connecting element 320 and has a locked position and an unlocked position. In the locked position of the locking element 330, the locking element 330 can lock the pedal section 310 to the support tube 100 to make it easier for the passenger to place their feet; in the unlocked position, the pedal section 310 can slide up and down along the support tube 100 to be adjusted to an optimal position.

[0042] According to one embodiment, in the locked position of the locking element 330, the pedal section 310 can lock onto the outer circumferential surface of the support tube 100; in the unlocked position of the locking element 330, the pedal section 310 can slide up and down along the outer circumferential surface of the support tube 100 to be adjusted to the optimal position.

[0043] According to one embodiment, the locked position and the unlocked position of the locking element 330 can be triggered by pivoting the pedal section 310 relative to the connecting element 320.

[0044] According to one embodiment, the locking element 330 comprises at least one locking structure 331. The locking structure 331 is connected to the pedal section 310, and the rotation of the pedal section 310 can drive the rotation of the locking structure 331.

[0045] According to one embodiment, a locking projection 3311 is arranged on a surface of the locking structure 331 opposite the support tube 100. When the locking structure 331 moves into a Fig. When the pedal section 310 is rotated to the position shown in Figure 10, the locking projection 3311 of the locking structure 331 exposes an inner circumferential surface 327 of the connecting element 320 and thus presses against the outer circumferential surface of the support tube 100, which is received in the connecting element 320, thereby locking the footrest device 300 in this position. When the pedal section 310 is rotated to drive the locking projection 3311 of the locking structure 331 to rotate into a position that is retracted into the inner circumferential surface 327 of the connecting element 320, as shown in Figure 10, the locking projection 3311 of the locking structure 331 is engaged. Fig. As shown in Figure 11, the footrest device 300 is unlocked and can be adjusted up and down along the support tube 100.

[0046] According to one embodiment, the locking structure 331 is arranged on the pivot structure 3212 of the first connecting seat 321 or the pivot structure 3222 of the second connecting seat 322.

[0047] In particular, as in Fig. As shown in Figure 9, the locking element 330 comprises a locking structure 331, an attachment structure 332, and a fastening structure 333. According to the embodiment shown, two locking structures 331 are provided, and correspondingly, two attachment structures 332 and two fastening structures 333 are also provided. The two locking structures 331 are each arranged on the pivot structure 3212 of the first connecting seat 321 and the pivot structure 3222 of the second connecting seat 322, and they are opposite each other. Thus, when the first connecting seat 321 and the second connecting seat 322 of the connecting element 320 are attached to each other by their respective connecting structures to surround the support tube 100, the two locking structures 331 are arranged on opposite sides of the inner circumferential surface 327 of the connecting element 320 relative to the support tube 100.A locking projection 3311 is arranged on the side surface of the locking structure 331 opposite the support tube 100. For example, as in . Fig. As shown in Figure 9, two locking projections 3311, arranged symmetrically vertically, are provided, and the locking projection 3311 is preferably made of a soft rubber material, or the locking structure 331 is made entirely of a soft rubber material. A mounting projection 3312 is arranged on the side surface of the locking structure 331 opposite the support tube 100. Similarly, a mounting slot 3321 is arranged on the side surface of the mounting structure 332 opposite the locking structure 331. The locking structure 331 can be firmly connected to the mounting structure 332 by an interference fit between the mounting projection 3312 and the mounting slot 3321. However, the present disclosure is not limited to this, and other fastening connection methods may also be used.One end of the fastening structure 333 is attached to the mounting structure 332 and thus to the locking structure 331, and the other end of the fastening structure 333 is connected to the pedal section 310. For example, as shown in . Fig. Figure 9 shows that the other end of the fastening structure 333 is screwed into the pedal section 310 via a threaded structure. Specifically, the fastening structure 333 comprises a limiting element 3331 and a fastening element 3332. The limiting element 3331 interacts with a rotary slot 3212a located on the end face of the pivot structure of the connecting element 320 and is connected to the pedal section 310 after passing through the rotary slot 3212a. The fastening element 3332 is connected to the pedal section 310 after passing through the connecting hole 3212b located on the end face of the pivot structure of the connecting element 320. Corresponding to the two symmetrically arranged arcuate elongated rotary slots 3212a, two limiting elements 3331 are also provided, and each of the two limiting elements 3331 is inserted through the two rotary slots 3212a.

[0048] With the above structure, the rotation of the pedal section 310 can trigger the limiting element 3331 to slide along the rotary slot 3212a, thereby driving the rotation of the locking structure 331. In particular, with reference to Fig. 10 and Fig. 11, Fig. 10 the locking element 330 in the locked state, and Fig. Figure 11 shows the locking element 330 in the unlocked state. By rotating the pedal section 310, the limiting element 3331, which is rigidly connected to the pedal section 310, rotates along the rotary slot 3212a, thus driving the locking structure 331, which is rigidly connected to the mounting structure 332, to rotate. When the locking structure 331 moves into the Fig. The 10 shown positions rotate, combined with reference to Fig. 9. When the locking projection 3311 of the locking structure 331 rotates into the upper and lower positions, the locking projection 3311 exposes the inner circumferential surface 327 of the connecting element 320 and thus presses against the outer circumferential surface of the support tube 100, which is received in the connecting element 320, thereby locking the footrest device 300 in this position. If it is necessary to adjust the position of the pedal section 310, the pedal section 310 must first be rotated, and the limiting element 3331 drives the locking projection 3311 of the locking structure 331 to rotate accordingly. For example, when rotated into the horizontal position, since the inner circumferential surface 327 of the connecting element 320 is an arcuate surface, the locking projection 3311 can retract into the inner circumferential surface 327 of the connecting element 320 in the horizontal position, as shown in Fig. Figure 11 shows that at this point, the footrest device 300 is unlocked and can be adjusted up and down along the support tube 100. After adjusting it to a suitable position, the footrest device 300 can be locked again by turning the pedal section 310.

[0049] The footrest device 300 described above can be mounted on the support tube 100 of the child carrier 1, providing a place for the passenger to rest their feet and improving the driving experience. Meanwhile, the movable plate 312 of the pedal section 310 is pivotable and foldable relative to the stationary plate 314, allowing it to meet the requirements of some regulations that the overall width of the support mechanism be less than 200 mm. Furthermore, the height of the footrest device 300 is freely adjustable, and operation is simple.

[0050] Next, a footrest device 300 according to another embodiment is described with reference to Fig. 12 and Fig. 13 described. The pedal section 310 of the footrest device 300 in this embodiment is not foldable, but the footrest device 300 can be fully connected to the support tube 100 by having the clamping element 360 in a clamped position, or detached from the support tube 100 by having the clamping element 360 in a release position. Fig. Figure 12 shows the clamped position of the clamping element 360, in which the footrest device 300 is connected to the support tube 100 so that the passenger can place his feet; Fig. Figure 13 shows a state in which the clamping element begins to open 360 degrees.

[0051] In particular, as in Fig. 14 and Fig. Figure 15 illustrates the specific structure of the clamping element 360, which is connected to the connecting element 320 so that the connecting element 320 can be opened by the clamping element 360 to release the footrest device 300. As shown in Fig. As shown in Figure 15, the clamping element 360 comprises an inner clamping element 361 and an outer clamping element 362. The inner clamping element 361 is pivotally connected to the connecting element 320 by a first pivot shaft 325, for example, pivotally connected to the first connecting seat 321 of the connecting element 320; the outer clamping element 362 is pivotally connected to the connecting element 320 by a second pivot shaft 326, for example, pivotally connected to the second connecting seat 322 of the connecting element 320. The structure of the connecting element 320 in this embodiment is essentially the same as that of the connecting element 320 in the first embodiment described above, both comprising a first connecting seat 321 and a second connecting seat 322, which are connected to each other. Each of the first connecting seat 321 and the second connecting seat 322 comprises a connecting structure and a pivoting structure.The ends of the connecting structures are joined together by a closure. The difference from the first embodiment is that the other ends of the connecting structure are not joined together by a closure as in the first embodiment, but are pivotably connected to the inner clamping element 361 and the outer clamping element 362 by the first pivot shaft 325 and the second pivot shaft 326, respectively.

[0052] A clamping pad 3612 (shown in Fig. 14) is arranged on an inner surface of the inner clamping element 361 opposite the support tube 100, and the clamping lining 3612 is preferably made of a soft rubber material. A receiving slot 3611 (shown in Fig. 15) is arranged on an opposite outer surface of the inner clamping element 361. In the clamped position of the clamping element 360, the outer clamping element 362 can be partially received in the receiving slot 3611. Combined with reference to Fig. 16 A locking hook 3621 is arranged at one end of the outer clamping element 362 away from the second pivot shaft 326. Accordingly, a locking rib 3213 (shown in Fig. 16) arranged on the surface of the connecting element 320, for example at the position of the surface corresponding to the first connecting seat 321. Based on the above structure, as shown in Fig. As shown in Figure 15, the inner clamping element 361 can be pivoted clockwise around the first pivot shaft 325 so that the clamping lining 3612 of the inner clamping element 361 presses against the surface of the support tube 100 to form an interference fit, and the outer clamping element 362 can be pivoted counterclockwise around the second pivot shaft 326. The outer clamping element 362 clamps the inner clamping element 361 and can be partially received in the receiving slot 3611, which is arranged on the outer surface of the inner clamping element 361, and further enables the locking hook 3621 of the outer clamping element 362 to interact with the locking rib 3213, which is arranged on the connecting element 320, thereby locking the clamped state of the clamping element 360 and locking the foot support device 300 to the support tube 100.

[0053] An actuating slot 3622 can also be arranged on the outer clamping element 362. The actuating slot 3622 is preferably arranged near the locking hook 3621 to save force and facilitate operation. Force can be exerted through the actuating slot 3622 to pivot the outer clamping element 362 in the opposite direction (for example, clockwise, as shown in the figure). Fig. 15), and then the inner clamping element 361 is also pivoted in the opposite direction (for example, counterclockwise with reference to the figure of Fig.15), so that the clamping element 360 can be released. At this point, the position of the footrest device 300 can be adjusted or the footrest device 300 can be released. Certainly, in the clamped position of the clamping element 360, the rotation of the locking element 330 can be triggered by rotating the pedal section 310 to adjust the height of the footrest device 300, and the operating process is the same as that of the first embodiment, which is not repeated.

[0054] The structures of other components in this embodiment are the same as those in the first embodiment and are not described again.

[0055] The footrest device 300 according to this embodiment can be easily detached from the support tube 100, thus eliminating the need for a movable plate and a stationary plate pivotally connected to each other. The structure is simpler, and it can also meet the requirements of some regulations that the overall width of the support mechanism be less than 200 mm. Its locking and unlocking operations are also very simple and easy to use.
