Description

Technical Field

[0001] This application relates to a canopy connection structure for a child carrier, a child seat, and a child carrier.

Background Art

[0002] Child carriers (e.g., child seats or child carts) generally have a canopy provided to avoid direct sunlight and foreign objects from entering the seat body. The canopy can be manually deployed or folded to meet various user needs.

[0003] In addition, to accommodate children of different sizes, child seats generally have an electric angle adjustment mechanism for adjusting the angle of the child seat. Generally, the operating device of the angle adjustment mechanism is disposed on the seat body or the base of the child seat to facilitate operation. However, for a driver such as a parent, it is difficult to touch the operating device to adjust the angle of the seat when driving the vehicle. In addition, when the child seat rotates or the angle of the seat is adjusted, the wires can easily become entangled.

[0004] In addition, to meet the seating needs of children of different ages, the child seat can be set in both a forward-use mode and a rearward-use mode. Among these, children in a younger group (e.g., 0 to 9 months) usually need to sit on the child seat in the rearward-use mode to maximize the safety of the child. However, a caregiver may accidentally put a younger child in the child seat in the forward-use mode due to negligence, improper use, etc. during use, which is not helpful for the child seat to fulfill its safety guarantee role.

[0119] First Embodiment

[0120] Figures 1 to 3 show a side view and a perspective view of a child carrier 1000 to which a canopy connection structure 300 (see Figure 6, hereinafter referred to as the canopy connection structure 300) according to one embodiment of this application is applied. More specifically, the child carrier 1000 includes a main body 100, a canopy 200, and a canopy connection structure 300. The canopy 200 is detachably attached to the main body 100 by using the canopy connection structure 300. Hereinafter, the canopy connection structure 300 will be described together with the child carrier 1000.

[0121] Figures 1 to 3 show that in this embodiment, a child carrier 1000 is illustrated using a child seat as an example. For example, the main body 100 includes a seat body (also referred to as a seat) 11 and a base 12. More specifically, the main body portion 121 of the base 12 is placed on a vehicle seat (not shown) and is designed to be plugged into an ISOFIX socket on the vehicle seat using an ISOFIX plug-in. The base 12 is provided with legs 123, the upper ends of which are pivotally connected to a connecting seat 122, which is disposed on the main body portion 121. The lower ends of the legs 123 are configured to contact the floor inside the vehicle. The seat body 11 is rotatably mounted on the base 12 so that it can provide the child with a forward-facing and rear-facing position. Of course, in some alternative embodiments, the main body 100 may have other implementation forms. For example, the seat body 11 and the base 12 may not be rotatable relative to each other, but may be fixedly attached to each other, and the base 12 may not be provided with legs 123.

[0122] It should be noted that the product types of child carriers 1000 to which the canopy connection structure 300 provided in this embodiment of the present application may be applied are not limited to the child seats enumerated in this embodiment. In some alternative embodiments, the child carrier 1000 may be, for example, a baby basket, a child cart, a baby crib, etc. It will be understood that the implementation form of the main body 100 will vary depending on the product type of the child carrier 1000.

[0123] Referring to Figures 1 to 3 and Figure 6, in this embodiment, the canopy 200 is detachably attached to the seat body 11 of the main body 100. More specifically, the canopy 200 is detachably attached to mounting positions 110 located on both sides of the backrest housing 111 of the seat body 11. Referring to Figures 1, 4, and 5, the canopy 200 includes, for example, an active bracket 21, a positioning bracket 22, and a tarpaulin 23 (shown by a dashed line in Figure 1). The active bracket 21 is pivotably connected to the positioning bracket 22. The positioning bracket 22 is configured to be fastened to the seat body 11. The tarpaulin 23 is connected to the active bracket 21 and the positioning bracket 22, respectively.

[0124] When the canopy 200 is attached to the seat body 11 of the main body 100, the positioning bracket 22 is fixed to the seat body 11 and is no longer movable relative to the seat body 11. Rotation of the active bracket 21 relative to the positioning bracket 22 can drive the tarpaulin 23 to be deployed or folded, thereby giving the canopy 200 an deployed state (see Figure 1) and a folded state (see Figure 2). In some alternative embodiments, the canopy 200 may further have at least one intermediate state (e.g., a half-open state) between the deployed and folded states. Referring to Figure 1, the canopy 200 may further include at least one auxiliary bracket 24 connected to the tarpaulin 23. The auxiliary bracket 24 may be pivotably connected to both the positioning bracket 22 and the active bracket 21, for example, or the auxiliary bracket 24 may be fixedly connected only to the tarpaulin 23. When the canopy 200 is deployed, the auxiliary bracket 24 is configured to support the tarpaulin 23 between the active bracket 21 and the positioning bracket 22.

[0125] We will continue to refer to the structure of the canopy 200 shown in Figures 4 and 5. In this embodiment, for example, both the active bracket 21 and the positioning bracket 22 are substantially U-shaped. The active bracket 21 includes two first connectors 211, which are located at the two ends of the U-shaped structure of the active bracket 21. The positioning bracket 22 includes two second connectors 222, which are located at the two ends of the U-shaped structure of the positioning bracket 22. The two first connectors 211 and the two second connectors 222 are each pivotably connected, thereby allowing the active bracket 21 to rotate around the rotation axis X1-X1 relative to the positioning bracket 22. More specifically, taking a pair of pivotably connected first and second connectors 211 and 222 as an example, the first connector 211 includes, for example, a laterally extending cylindrical structure, and the second connector 222 includes, for example, a circular ring structure, with the cylindrical structure of the first connector 211 being sleeve-mounted onto the circular ring structure of the second connector 222. In some alternative embodiments, the first connector 211 and the second connector 222 may be pivotably connected to each other by other suitable structures.

[0126] Referring to the three-dimensional structure of the main body 100 shown in Figure 6, in this embodiment, the canopy connection structure 300 includes two drive units 31, which are respectively attached to two sides of the backrest housing 111 of the seat body 11. Each drive unit 31 has a power output member 311, which has the aforementioned rotation axis X1-X1 (see Figure 8). Each power output member 311 is configured to be non-rotatably connected to the corresponding first connection portion 211 of the active bracket 21 of the canopy 200. Referring to the functional module diagram of the control system of the canopy connection structure 300 shown in Figure 7, the canopy connection structure 300 may further include a control device 32. The control device 32 is signal-connected to the drive units 31 and is configured to control the power output member 311 to drive the active support 21 to rotate around the rotation axis X1-X1 so that the canopy 200 can be automatically deployed or folded.

[0127] The child carrier 1000 provided in this embodiment of the present application drives the active bracket 21 of the canopy 200 to rotate by the control device 32 and the drive device 31 so as to automatically unfold or fold the canopy 200, thereby performing automatic control of the state adjustment operation of the canopy 200.

[0128] Referring to Figures 3 and 7, the control device 32 of this embodiment includes, for example, a printed circuit board (not shown) and a control panel 321 attached to the connection seat 122. In some alternative embodiments, the control device 32 may be located in any suitable location on the main body 100, or it may be located outside the main body 100.

[0129] Referring to Figure 3, the control panel 321 may include a plurality of operation buttons 3211. For example, the plurality of operation buttons 3211 may include, but are not limited to, a start button for starting the drive unit 31, a stop button for stopping the drive unit 31, an deployed state button corresponding to the deployed state of the canopy, a folded state button corresponding to the folded state of the canopy, and an intermediate state button corresponding to an intermediate state of the canopy. The user may randomly adjust the state of the canopy 200 by operating the start and stop buttons, or adjust the canopy 200 to a corresponding state by operating the buttons corresponding to different states of the canopy. In some embodiments, the control panel 321 may include a touchscreen (not shown), and the user may adjust the state of the canopy 200 by tapping an instruction area on the touchscreen. Naturally, in some embodiments, the control panel 321 may adjust the state of the canopy 200 by operating the buttons 3211 in combination with the touchscreen.

[0130] Referring to Figure 7, the control unit 32 may further include a wireless communication module 322. The wireless communication module 322 is configured to communicate wirelessly with an external device 39. The external device 39 may be, but is not limited to, various mobile devices such as a mobile phone, smartwatch, or smart bracelet, or it may be the vehicle's central control system. In some embodiments, the wireless signal may be, for example, a Bluetooth signal or a WiFi signal. The wireless transmission path or network may be a local area network such as a Bluetooth transmission, WiFi, or WAPI network. Naturally, the network may be a mobile communication network such as 2G, 3G, 4G, or 5G. The wireless communication module 322 is configured to receive canopy adjustment commands sent by the external device 39, and the control unit 32 controls the operation of the drive unit 31 in response to the canopy adjustment commands so that the canopy 200 can be adjusted to the desired state.

[0131] By configuring the wireless communication module 322 for the control device 32, the user can remotely adjust the state of the canopy 200. For example, in some typical use scenarios, a user in the driving position can adjust the state of the canopy 200 of the child carrier 1000 mounted on the rear seat of the vehicle by operating an external device 39, eliminating the need for the user to leave the driving position while adjusting the state of the canopy 200, which provides the user with great convenience.

[0132] Referring to Figures 8 and 11, the canopy connection structure 300 in this embodiment may further include a position detection device 33. The position detection device 33 is signal-connected to a control device 32 and is configured to send position signals to the control device 32 regarding the moving position of the active bracket 21. When the power output member 311 drives the active bracket 21 to a predetermined position, the control device 32 controls the drive device 31 to stop driving the active bracket 21, thereby allowing for more precise adjustment of the state of the canopy 200. The predetermined position of the active bracket 21 corresponds, for example, to the canopy 200 being deployed, folded, or any intermediate state between the deployed and folded states (e.g., half-open).

[0133] Referring to Figures 8 and 11, this embodiment further illustrates an exemplary embodiment of the position detection device 33. The position detection device 33 includes, for example, a photoelectron sensor, more specifically, a photoelectron emitter 331 and a photoelectron receiver 332. The position detection device 33 is arranged around the power output member 311 and indirectly obtains the movement position of the active bracket 21 by detecting the rotational position of the power output member 311.

[0134] More specifically, the power output member 311 has, for example, an annular flange 3111 located between a photoelectron emitter 331 and a photoelectron receiver 332. In some embodiments, the annular flange 3111 is provided with at least two detection ports 3110 in the circumferential direction. As the annular flange 3111 rotates together with the power output member 311, the detection ports 3110 pass between the photoelectron emitter 331 and the photoelectron receiver 332, the photoelectron receiver 332 receives a signal from the photoelectron emitter 331, the position detection device 33 sends the position signal to the control device 32, which can then determine whether the active bracket 21 has rotated to a predetermined position according to the position signal.

[0135] Naturally, the implementation form and mounting position of the position detection device 33 are not limited to the above examples, as long as it can detect a position signal relating to the movement position of the active bracket 21. For example, in some alternative embodiments, the position detection device 33 can directly detect the movement position of the active bracket 21. In addition, the type of position detection device 33 is not limited to a photoelectron sensor. In some alternative embodiments, the position detection device 33 may be, for example, a proximity switch, a Hall sensor, or an encoder.

[0136] Referring to Figures 4 and 6, this embodiment shows an exemplary connection between the power output member 311 and the first connection portion 211 of the active bracket 21. As described above, the first connection portion 211 has a laterally extending cylindrical structure, the cylindrical structure has a laterally extending groove 2110, and the power output member 311 has a cylindrical structure that is inserted into the groove 2110, thereby sleeve-fitting the first connection portion 211 with the power output member 311. One of the peripheral walls of the groove 2110 and the peripheral wall of the cylindrical structure of the power output member 311 is provided with at least one protrusion 251, and the other is provided with at least one recess 252. Since the protrusion 251 and the recess 252 are engageable with each other, they can be used as a rotation restricting mechanism 25 to restrict relative rotation between the first connection portion 211 and the power output member 311.

[0137] Naturally, in some alternative embodiments, the connection between the power output member 311 and the first connector 211 is not limited to the sleeve connection described above. The power output member 311 and the first connector 211 may be non-rotatably connected by other suitable structures. In addition, in embodiments in which the power output member 311 is sleeve-mounted with the first connector 211, the rotation restricting mechanism 25 used to restrict relative rotation between the power output member 311 and the first connector 211 is not limited to the convex portion 251 and concave portion 252 described above. For example, in some alternative embodiments, the power output member 311 and the first connector 211 restrict relative rotation between them by notched surfaces that are in contact with each other.

[0138] Referring to Figure 6, in this embodiment, a hole is provided at the mounting position 110 of the backrest housing 111, and the power output member 311 is located inside the backrest housing 111 and corresponds to the hole at the mounting position 110. When the canopy 200 is attached to the seat body 11 of the main body 100, the first connection portion 211 of the active bracket 21 extends from the hole at the mounting position 110 into the interior of the backrest housing 111 and is sleeve-mounted with the power output member 311. In some alternative embodiments, the power output member 311 may protrude from the hole at the mounting position 110, and the first connection portion 211 is sleeve-mounted with the first connection portion 211 outside the backrest housing 111.

[0139] Referring to Figure 6, in this embodiment, the engagement hole 112 is located on the main body 100 (more specifically, on the backrest housing 111), and the engagement hole 112 is offset from the mounting position 110. Referring to Figure 5, the positioning bracket 22 is provided with an engagement support column 221, which is located, for example, adjacent to the second connection portion 222. When the canopy 200 is attached to the main body 100, the engagement support column 221 is inserted into the engagement hole 112, thereby locking the relative position between the positioning bracket 22 and the main body 100. When it is necessary to remove the canopy 200, the active bracket 21 and the positioning bracket 22 can be extended horizontally, and the active bracket 21 and the positioning bracket 22 can be elastically deformed. This allows the two first connecting parts 211 to be moved in opposite directions in the direction of the rotation axis X1-X1 to disengage from the power output member 311, and the two second connecting parts 222 to be moved in opposite directions in the direction of the rotation axis X1-X1 to remove the engaging support 221 from the engaging hole 112, thereby allowing the canopy 200 to be moved so that it can be separated from the main body 100. Of course, in other embodiments, the positioning bracket 22 may be immovably connected to the main body 100 via other suitable positioning mechanisms. For example, in some alternative embodiments, the outer shape of the backrest housing 111 may have a positioning groove formed for engaging with the positioning bracket 22.

[0140] Figures 8 to 13 show perspective views, exploded views, and cross-sectional views of some components of the canopy connection structure 300 of this embodiment. The canopy connection structure 300 may further include a mounting seat 35 fastened to the inside of the backrest housing 111 of the main body 100 by fasteners (not shown) passing through through holes 350. The drive unit 31 may further include a power source 313 and a transmission mechanism 312 (see Figure 12). Both the power source 313 and the transmission mechanism 312 are mounted on the mounting seat 35. The power source 313 is configured to output power, and the transmission mechanism 312 is configured to transmit the power output from the power source 313 to a power output member 311. The mounting seat 35 may further include a holder 353, and the position detection device 33 is mounted on the holder 353, for example.

[0141] More specifically, referring to Figure 9, the power source 313 is, for example, an electric motor (or also referred to as a motor) attached to the mounting seat 35 by a fastener 3132. The power source 313 is signal-connected to the control device 32, and the power source 313 receives commands from the control device 32 to drive the power output member 311 to rotate or to stop driving the power output member 311 to rotate. For example, the transmission mechanism 312 is a gear transmission mechanism, which includes a drive gear 3123 and an output gear 3122. The drive gear 3123 is drivably connected to the output shaft 3131 of the power source 313. The drive gear 3123 is, for example, directly and non-rotatably connected to the output shaft 3131, or non-rotatably connected to the output shaft 3131 via an intermediate member 3133 installed in between. The drive gear 3123 and the output gear 3122 may mesh directly with each other, or they may mesh indirectly.

[0142] The output gear 3122 and the power output member 311 are coaxially connected by a fastener 36. The fastener 36 may be, for example, a rivet or a bolt. The output gear 3122 has first end face teeth 3121, and the power output member 311 has second end face teeth 3112, with the first end face teeth 3121 meshing with the second end face teeth 3112. Power output by the power source 313 is transmitted to the output gear 3122 via the drive gear 3123, and then to the power output member 311 via the meshing first end face teeth 3121 and second end face teeth 3112. The power output member 311 drives and rotates the active bracket 21, adjusting the state of the canopy 200.

[0143] Figures 10 to 13 show exemplary assembled structures of the power source 313, the transmission mechanism 312, and the power output member 311. For example, the mounting seat 35 is provided with a first mounting hole 351, and the drive gear 3123 is drivably connected to the output shaft 3131 of the power source 313 in the first mounting hole 351. For example, the mounting seat 35 is further provided with a second mounting hole 352, and the output gear 3122 and the power output member 311 are coaxially connected to each other by fasteners 36 attached to the second mounting hole 352.

[0144] More specifically, the second mounting hole 352 is of the stepped type, and the output gear 3122 has a cylinder 31221 that is sleeve-mounted in the second mounting hole 352. The output gear 3122 has a central hole 31220, and the power output member 311 has a cylinder 3113 that is sleeve-mounted in the central hole 31220. The power output member 311 has a first stepped hole 310. The fastener 36 is sleeve-mounted in the second mounting hole 352, the central hole 31220, and the first stepped hole 310, and functions as the rotating shaft for the output gear 3122 and the power output member 311. Thus, the shaft of the fastener 36 forms the rotation axis X1-X1 of the power output member 311. The first end 361 of the fastener 36, which is away from the output gear 3122, is located inside the first stepped hole 310, which facilitates a compact overall structure. Naturally, in some alternative embodiments, the first stepped hole 310 may be replaced by a straight hole, which is also within the scope of protection of this application. In addition, the first end 361 of the fastener 36 may protrude outward from the power output member 311.

[0145] Referring to Figures 12 and 13, in this embodiment, the power output member 311 can be sleeve-mounted on a fastener 36 so as to be axially movable. The canopy connection structure 300 further includes an elastic member 34, which is configured to apply an elastic force to the power output member 311 that presses it against the output gear 3122, thereby keeping the first end face teeth 3121 and the second end face teeth 3112 engaged with each other.

[0146] Referring to Figures 10 and 11, the first end face teeth 3121 have an inclined portion 31212, and the second end face teeth 3112 have an inclined portion 31122. When the power output member 311 is subjected to a relatively large circumferential force from the outside, for example, when a user manually adjusts the state of the canopy 200 by applying a circumferential force to the active bracket 21, under the action of the inclined portions 31212 and 31122, the power output member 311 can rotate around the fastener 36 relative to the output gear 3122 and move along the fastener 36 away from the output gear 3122, so that the first end face teeth 3121 and the second end face teeth 3112 disengage from each other (i.e., the state shown in Figure 13), allowing the user to manually adjust the state of the canopy 200. In other words, the user does not need to drive and rotate the output gear 3122 during manual adjustment of the canopy 200, thereby avoiding damage to the power source 313. In some alternative embodiments, the above technical effects can be achieved even when only one of the first end face teeth 3121 and the second end face teeth 3112 is provided. In addition, in some alternative embodiments, each tooth of the first end face teeth 3121 and the second end face teeth 3112 may have an arc profile to allow the user to manually adjust the position of the canopy 200.

[0147] It should be noted that the shapes of the first end face teeth 3121 and the second end face teeth 3112, as well as the meshing depth of the end face teeth, may be appropriately set to ensure that the power output member 311 rotates smoothly and in sync with the output gear 3122 when the power source 313 drives the output gear 3122.

[0148] Referring to Figures 12 and 13, to facilitate the installation of the elastic member 34, the restricting member 37 is disposed at the first end 361 of the fastener 36, and the elastic member 34 is interposed between the restricting member 37 and the power output member 311. In this embodiment, the restricting member 37 and the elastic member 34 are located in the first stepped hole 310. The restricting member 37 is slidably engaged with the first stepped hole 310, and the elastic member 34 may be a spring sleeved on the fastener 36. More specifically, the first stepped hole 310 includes a first stepped portion 3101 and a second stepped portion 3102, the first stepped portion 3101 being closer to the restricting member 37 than the second stepped portion 3102. The restricting member 37 is configured to restrict the axial movement stroke of the first stepped portion 3101. The elastic member 34 is interposed between the regulating member 37 and the second stepped portion 3102. In some alternative embodiments, the second stepped portion 3102 may not be provided, and the elastic member 34 is interposed between the regulating member 37 and the first stepped portion 3101.

[0149] Referring to Figures 8, 12, and 13, in this embodiment, the regulating member 37 and the power output member 311 cannot rotate relative to each other. More specifically, the outer circumferential contour of the regulating member 37 concavely coincides with the inner circumferential contour of the first stepped hole 310 of the power output member 311. The regulating member 37 has a second stepped hole 370, which sleeves the regulating member 37 onto the fastener 36, more specifically, the first end 361 of the fastener 36 is located inside the second stepped hole 370. In some embodiments, a washer 38 sleeved onto the fastener 36 may be further disposed in the second stepped hole 370, and the washer 38 may be made of a wear-resistant material having a low coefficient of friction. In some alternative embodiments, the regulating member 37 is integrated with the fastener 36, for example. In some alternative embodiments, the regulating member 37 has a cylindrical structure that is pivotably connected to, for example, the first stepped hole 310 of the power output member 311.

[0150] The following briefly describes the work process of the child carrier 1000 when adjusting the canopy state, to which the canopy connection structure 300 according to the first embodiment of this application is applied.

[0151] Child carrier 1000 is, for example, a child seat that is installed in the rear seat of a vehicle. When a user (driver or another passenger in the seat) wants to automatically adjust the canopy of the child seat to a desired state, the user can send a canopy adjustment command to the control device 32 by operating an external device 39 (such as a vehicle's portable terminal or central control system) or a control panel 321. After receiving the canopy adjustment command, the control device 32 sends a signal to the drive unit 31, and the power source 313 of the drive unit 31 transmits power to the power output member 311 via the transmission mechanism 312. The power output member 311 drives the active bracket 21 to rotate until the position detection device 33 detects that the power output member 311 has rotated to a certain position (corresponding to the desired state of the canopy 200), and the control device 32 controls the power source 313 to stop outputting power. The canopy 200 is then held in the desired state.

[0152] For example, the canopy connection structure 300 provided in the first embodiment of this application may be modified as follows.

[0153] I. In some alternative embodiments, for example, the main body 100 is provided with a slide track that slidably cooperates with the active bracket 21 of the canopy 200, and the control device 32 controls a power output member 311 to drive the active bracket 21 to move along the slide track so that the canopy 200 can be deployed or folded.

[0154] II. In some alternative embodiments, the canopy 200 is irremovably connected to the main body 100, for example. For example, a fastener 36 irremovably attaches the first connection portion 211 of the active bracket 21 to the main body 100.

[0155] III. In some alternative embodiments, the transmission mechanism 312 having the output gear 3122 is not limited to a gear transmission mechanism. For example, the transmission mechanism 312 may include a gear rack transmission mechanism or a worm gear transmission mechanism.

[0156] IV. In some alternative embodiments, the canopy connection structure 300 may include a drive unit 31, where a first connection portion 211 of the active bracket 21 is connected to a power output member 311 of the drive unit 31, and another first connection portion 211 is pivotably connected to the main body 100.

[0157] V. In some alternative embodiments, the drive unit 31 may not be provided with a drive gear 3123, and the output shaft 3131 of the power source 313 is arranged coaxially with the output gear 3122 and is non-rotatably connected to the output gear 3122. Power from the power source 313 can be transmitted to the output gear 3122 over a short distance. In some embodiments, the output shaft 3122 may be directly connected to the output gear 3122, for example, by a spline connection or a notched connection, or by an intermediate member located between them.

[0158] Second Embodiment

[0159] Figures 14 and 15 show a side view and a perspective view of a child carrier 1000 to which a canopy connection structure 300 according to one embodiment of this application is applied. Where there is no contradiction, the structure of the child carrier 1000 and the canopy connection structure 300 in this second embodiment can be described by referring to the description of the first embodiment above.

[0160] Referring to Figures 14 and 15, unlike the first embodiment, the canopy 200 of this second embodiment does not need to be provided with a positioning bracket 22, and features related to the positioning bracket 22 may be omitted accordingly. More specifically, the canopy 200 in this second embodiment includes an active bracket 21 and a tarpaulin 23. The tarpaulin 23 is connected to the main body 100 and the active bracket 21. The tarpaulin 23 is connected, for example, to the upper part of the backrest housing 111 of the seat body 11. When the control device 32 controls the power output member 311 to drive and move the active bracket 21, the canopy 200 can be automatically deployed or folded.

[0161] In this second embodiment, the active bracket 21 and the main body 100 may be detachable or non-detachable connections. The tarpaulin 23 and the main body 100 may also be detachable or non-detachable connections, respectively.

[0162] The canopy connection structure 300 provided in the first and second embodiments of this application may also be applied to the following third and fourth embodiments.

[0163] Third Embodiment

[0164] Referring to Figures 16 to 18, a third embodiment of this application provides an angle-adjustable child seat 100a. Where there is no contradiction, the structure of the child seat 100a provided in this third embodiment can refer to the child seat described in the preceding embodiments. The canopy connection structure 300 described above can also be applied to the child seat.

[0165] Referring to Figures 16-18, the child seat 100a includes a base 12 and a seat body 11. The seat body 11 is slidably connected to the base 12, and the angle of the seat body 11 relative to the base 12 (also referred to as the tilt angle) changes as the seat body 11 slides relative to the base 12. For example, referring to Figures 17 and 18, since the seat body 11 is slidable relative to the base 12, the tilt angle of the seat body 11 switches between an upright position shown in Figure 17 and a reclined position shown in Figure 18. The seat body 11 may further have multiple tilt positions between the upright and reclined positions to satisfy the requirements of individual sitting and sleeping positions for infants. In some embodiments, the seat body 11 may be a baby basket.

[0166] Referring to Figures 19 to 21, in one embodiment, the child seat 100a further includes a slide rod 131, a slide groove 113, a drive rod 114, and a drive mechanism 41.

[0167] The slide rod 131 is disposed on the base 12. In some embodiments, the base 12 is provided with a rotating member 13, and more specifically, the slide rod 131 is disposed on the rotating member 13. The slide groove 113 is formed, for example, on the seat body 11. The slide rod 131 can be inserted into the slide groove 113, and the slide rod 131 slides within the slide groove 113, guiding the seat body 11 to slide relative to the base 12, thereby adjusting the tilt angle of the seat body 11.

[0168] In this embodiment, the rotating member 13 can pivot with respect to the base 12 around the rotation axis X2-X2, and the seat body 11 and the rotating member 13 do not have to be relative to each other around the rotation axis X2-X2. Therefore, when the rotating member 13 pivots with respect to the base 12, the seat body 11 can be switched between a forward-facing use position and a rearward-facing use position.

[0169] The drive rod 114 is disposed on the seat body 11. The drive mechanism 41 is disposed on the base 12. More specifically in this embodiment, the drive mechanism 41 is disposed on the rotating member 13. The drive mechanism 41 is coupled to the drive rod 114 and can reciprocate by pressing the drive rod 114 to drive the seat body 11 to slide relative to the base 12, thereby automatically adjusting the tilt angle of the seat body 11.

[0170] Alternatively, the slide groove 113 is formed as an arc groove, and the drive mechanism 41 is pivotably connected to the base 12. More specifically in this embodiment, the drive mechanism 41 is pivotably connected to the rotating member 13. As the seat body 11 slides, the drive mechanism 41 can swing relative to a pivot point between the drive mechanism 41 and the base 12 (or rotating member 13). The direction in which the pivot axis of the drive mechanism 41 extends relative to the base 12 is perpendicular to the direction of reciprocating movement of the drive rod 114.

[0171] Alternatively, the seat body 11 and the slide groove 113 are a single integrated part, and the inner circumferential wall of the slide groove 113 is made of plastic material. Alternatively, referring to Figure 21, the seat body 11 is provided with a reinforcing member 1122 that extends in the vertical direction, and the slide groove 113 is disposed on the reinforcing member 1122.

[0172] Referring to Figure 21, in one embodiment, a reinforcing member 1133 is further disposed outside the slide groove 113. The reinforcing member 1133 is a sheet-like structure, more specifically, a thin sheet. The reinforcing member 1133 is made of metal and may be fastened to the sheet body 11. The reinforcing member 1133 has a through groove 11331 corresponding to the shape of the slide groove 113, so that the slide rod 131 can slide within the through groove 11331. The installation of the reinforcing member 1133 increases the structural strength of the slide fitting structure formed by the slide rod 131 and the slide groove 113, thereby improving the service life of the slide fitting structure and preventing the slide rod 131 from wearing down within the slide groove 113 during sliding. Alternatively, the thickness of the reinforcing member 1133 is less than the depth of the slide groove 113.

[0173] The ends of the drive rod 114 are fixedly connected to two reinforcing members 1133, which are located on the left and right sides, respectively. The fixed connection of the drive rod 114 to the reinforcing members 1133 increases the connection strength between the drive rod 114 and the seat body 11, preventing the drive rod 114 from becoming loose or losing its fixed connection to the base 12 due to prolonged reciprocating motion.

[0174] Referring to Figures 28 and 34, in some embodiments the child seat 100a further includes a control mechanism 42. The control mechanism 42 is disposed on the seat body 11 and / or base 12 and is electrically connected to a drive mechanism 41. The control mechanism 42 is configured to send a control signal to the drive mechanism 41, which in turn drives the seat body 11 to slide relative to the base 12 according to the received control signal.

[0175] In one embodiment, a rotary connector 132 is positioned at the center of the rotating member 13, and an electrical slip ring 133 is positioned at the center of the rotary connector 132. The operation panel 431 and the control mechanism 42 (more specifically, the sheet circuit board 421 as described below) are electrically connected via the electrical slip ring 133. That is, the electrical connection between the base 12 and the sheet body 11 is achieved by using the electrical slip ring 133.

[0176] Alternatively, the control mechanism 42 may include a base circuit board 124 disposed on the base 12. Alternatively, the base circuit board 124 may be disposed below the operation panel 431 and electrically connected to the operation panel 431.

[0177] Referring to Figure 9, as described above, the base 12 further includes a rotating member 13 that is rotatably disposed on the base 12 and connected to the seat body 11. Since the rotating member 13 can rotate 360 ​​degrees relative to the base 12 along the rotation axis X2-X2, the seat body 11 can rotate relative to the base 12 and can be adjusted to face forward or backward in the direction of vehicle movement. As described above, the drive mechanism 41 is pivotably connected to the rotating member 13.

[0178] Referring to Figures 22 to 25, in one embodiment, the drive mechanism 41 includes a motor 411, a screw 412, a drive block 413, and a bracket 414. The motor 411 is fixed on the bracket 414. The screw 412 is rotatably disposed on the bracket 414, and the motor 411 is coupled to the screw 412 to drive the screw 412 to rotate. The drive block 413 is sleeve-mounted on the screw 412 and screwed onto the screw 412, and the drive block 413 is further connected to the seat body 11. Specifically, the drive block 413 is connected to the drive rod 114 of the seat body 11. The screw 412 and the drive block 413 are part of a screw nut drive mechanism. One end of the bracket 414 is pivotally connected to the base 12, for example, by a pivot pin 415. In embodiments where a rotating member 13 is provided, one end of the bracket 414 is pivotally connected to the rotating member 13. The other end of the bracket 414 is a free end. Alternatively, the free end of the bracket 414 is attached to the backrest of the seat body 11 with a sleeve.

[0179] Motor 411 drives the screw 412 to rotate, which in turn drives the drive block 413 to move along the longitudinal direction of the screw 412. For example, when the screw 412 rotates clockwise, the drive block 413 moves upward along the longitudinal direction of the screw 412. When the screw 412 rotates counterclockwise, the drive block 413 moves downward along the longitudinal direction of the screw 412. The movement of the drive block 413 along the longitudinal direction of the screw 412 drives the seat body 11 to slide relative to the base 12 in order to change the tilt angle of the seat body 11.

[0180] When the bracket 414 is pivoted relative to the base 12, the angle between the longitudinal and vertical directions of the screw 412 is always acute.

[0181] Referring to Figures 22 and 23, in one embodiment, as described above, the drive rod 114 is arranged on the seat body 11. The drive block 413 is provided with a connection hole 4131. The drive block 413 is connected to the seat body 11 by the drive rod 114 passing through the connection hole 4131. When the drive block 413 moves in the longitudinal direction of the screw 412, the drive block 413 drives the seat body 11 to slide relative to the base 12 when the drive rod 114 is fitted into the connection hole 4131.

[0182] Referring to Figures 24 and 25, in one embodiment, the motor 411 includes an output shaft 4111, with a first tooth 41111 disposed on the outer surface of the output shaft 4111. A drive gear 4121 is fixedly mounted on the screw 412, and the drive gear 4121 has a second tooth 41211. The motor 411 drives and rotates the screw 412 by meshing the first tooth 41111 with the second tooth 41211. The output shaft 4111 and the drive gear 4121 are, for example, part of a worm gear transmission mechanism. Specifically, when the output shaft 4111 of the motor 411 is rotated clockwise or counterclockwise, the rotational motion of the output shaft 4111 is transmitted to the screw 412 by the meshing between the first tooth 41111 and the second tooth 41211, thereby allowing the screw 412 to rotate, and in turn the motor 411 to drive the screw 412 to rotate.

[0183] Referring to Figure 25, in one embodiment, the drive block 413 is provided with a through hole 4132 having an internal thread, the through hole 4132 is sleeve-mounted on the screw 412, and the internal thread of the through hole 4132 engages with the external thread 4122 of the screw 412. The rotation of the screw 412 can be driven by the engagement of the internal thread with the external thread 4122 and by restricting the rotation of the drive block 413 around the axis of the screw 412 through an appropriate structure, thereby moving the screw 412 in the longitudinal direction. Specifically, the motor 411 can drive the screw 412 to rotate, the rotation of the screw 412 can drive the drive block 413 to move the screw 412 in the longitudinal direction, the movement of the drive block 413 can be transmitted to the drive rod 114, and the drive rod 114 can drive the seat body 11 to slide relative to the base 12.

[0184] Referring to Figures 22 to 24, in one embodiment, a housing slot 4142 is disposed on a bracket 414, and the two opposing ends of the housing slot 4142 are provided with a first mounting groove 41421 and a second mounting groove 41422, respectively, and a screw 412 can be rotatably disposed in the housing slot 4142. A drive block 413 is fitted into the housing slot and can move in the longitudinal direction of the housing slot 4142. The cooperation between the drive block 413 and the housing slot 4142 can restrict the rotation of the drive block 413 around the axis of the screw 412.

[0185] Referring to Figure 24, the first support member 4123 and the second support member 4124 are sleeve-mounted to the two opposing ends of the screw 412, and the first support member 4123 and the second support member 4124 are positioned in the first mounting groove 41421 and the second mounting groove 41422, respectively. When the screw 412 rotates, the first support member 4123 and the second support member 4124 rotate within the first mounting groove 41421 and the second mounting groove 41422, respectively. Alternatively, the first support member 4123 and the second support member 4124 are made of a wear-resistant material such as steel or copper.

[0186] Referring to Figure 23, in one embodiment, a first cover plate 4143 is disposed in a portion of the first mounting groove 41421 of the bracket 414, and the first cover plate 4143 covers the first mounting groove 41421 so as to restrict the first support member 4123 into the first mounting groove 41421. A second cover plate 4144 is disposed in a portion of the second mounting groove 41422 of the bracket 414, and the second cover plate 4144 covers the second mounting groove 41422 so as to restrict the second support member 4124 into the second mounting groove 41422. Alternatively, the first cover plate 4143 and the second cover plate 4144 are fastened to the bracket 414 by bolts, screws, etc.

[0187] Referring to Figure 22, in one embodiment, the bracket 414 is provided with a plurality of position sensors 4141. Alternatively, the plurality of position sensors 4141 are arranged on the bracket 414 at intervals along the longitudinal direction of the screw 412. The drive block 413 is provided with a detection piece 4133, for example, the detection piece 4133 is a thin sheet extending from the drive block 413, and the detection sheet 4133 protrudes from the bracket 414. When the drive block 413 moves along the longitudinal direction of the screw 412 to the extent that the detection piece 4133 enters the sensing area of ​​the position sensor 4141, the position sensor 4141 sends an identification signal to the control mechanism 42, and the identification signal is related to the tilt angle of the sheet body 11.

[0188] Alternatively, referring to Figures 19 and 22, the first position sensor 4141a and the third position sensor 4141c are positioned on the bracket 414, respectively, corresponding to the upper and lower limits of the motion stroke of the drive block 413. Referring to the orientations of Figures 19 and 22 to 25, the terms “upper limit” and “lower limit” in this specification refer to the ultimate position of the upward movement and the ultimate position of the downward movement of the drive block 413, respectively. Alternatively, the second position sensor 4141b is positioned on the bracket 414, corresponding to an intermediate position of the motion stroke of the drive block 413. Referring to the orientation of Figure 8, the term “intermediate position” in this specification refers to a substantial midpoint between the ultimate positions of the upward and downward movement of the drive block 413.

[0189] Referring to Figures 19 and 22, in one embodiment, the drive block 413 may be further provided with a restricting member 4134 that protrudes from the drive block 413 in the direction in which the drive block 413 moves. When the drive block 413 reaches the upper or lower limit of its motion stroke, the restricting member 4134 abuts against, for example, a suitable structure of the bracket 414 or the rotating member 13 to prevent the drive block 413 from continuing to move away from the upper or lower limit. For example, if the control mechanism 42 fails, the drive block 413 will continue to move away from the upper and lower limits after reaching the lower limit of its motion stroke. In this case, the restricting member 4134 abuts against the corresponding part of the bracket 414 to prevent the drive block 413 from continuing to move and avoid damage to the drive mechanism 41.

[0190] In this embodiment, the restricting member 4134 protrudes from the drive block 413 toward the motor 411, preventing it from colliding with and damaging the motor when the drive block 413 moves toward the motor 411. Alternatively, the restricting member 4134 is a projection disposed on the drive block 413 and extending toward the upper limit position or the lower limit position. Alternatively, the restricting member 4134 is formed integrally with the drive block 413. Alternatively, the restricting member 4134 is fixedly connected to the drive block 413. Alternatively, the restricting member 4134 is disposed on the side of the drive block 413 facing the lower limit position.

[0191] Referring to Figures 19 and 21, in one embodiment, a support plate 135 is fixedly connected to the rotating member 13. A single slide rod 131 passes through two opposing support plates 135. A slide groove 113 is provided on the seat body 11. The slide rod 131 is inserted into the slide groove 113 and slides within the slide groove 113 to guide the sliding of the seat body 11 relative to the base 12, thereby changing the tilt angle of the seat body 11.

[0192] Specifically, in this embodiment, the rotating member 13 is provided with two parallel slide rods, which are a first slide rod 1311 and a second slide rod 1312. The seat body 11 is provided with a first slide groove group 1131 and a second slide groove group 1132, the first slide groove group 1131 including two slide grooves 113 arranged opposite to each other, and the second slide groove group 1132 including two other slide grooves 113 arranged opposite to each other. The first slide rod 1311 is inserted into the first slide groove group 1131 and slides within the first slide groove group 1131. The second slide rod 1312 is inserted into the second slide groove group 1132 and slides within the second slide groove group 1132.

[0193] Alternatively, a reinforcing member 1133 is provided outside the slide groove 113 to reduce wear between the slide rod 131 and the slide groove 113. Specifically, the reinforcing member 1133 is a metal sheet-like structure with a through groove 11331 provided therein, which overlaps the slide groove 113. In this embodiment, the slide groove 113 is integrally disposed with the sheet body 11. Therefore, the slide groove 113 is formed from the plastic material of the sheet body 11. The slide groove 113 may be formed directly into a protruding structure in a mold cavity on the reinforcing member during the formation of the sheet body 11, for example, or it may be obtained by drilling a hole after the sheet body 11 has been formed. The two ends of the slide rod 131 are inserted into the slide groove 113, increasing the contact area between the slide rod 131 and the inner wall of the slide groove 113, thereby preventing damage to the slide groove 113, which is made of plastic material, due to locally excessive force. When the slide rod 131 slides within the slide groove 113, the plastic slide groove 113 helps reduce the noise generated when the slide rod 131 slides. Furthermore, since the slide groove 113 is formed from the plastic material of the sheet body 11, the manufacturing cost is low.

[0194] As described above, in some embodiments, a reinforcing member 1133 made of metal is disposed in each slide groove 113, and a through groove 11331 is disposed in the reinforcing member 1133, with the through groove 11331 corresponding to the shape of the slide groove 113. Each slide rod 131 is slidably fitted into the corresponding slide groove 113 and through groove 11331, thereby reducing wear between the slide rod 131 and the slide groove 113. Furthermore, by installing the reinforcing member, the structural strength of the slide groove 113 can be ensured.

[0195] Compared to a solution in which the slide groove 113 is disposed on the mounting base 13 and the slide rod 131 is disposed on the seat body 11, the slide groove 113 in this embodiment can be formed integrally with the seat body 11, and the slide groove can have sufficient structural strength without being formed on a metal part. The structural strength of the slide groove can be further increased by using the reinforcing member 1133. The solution of this embodiment further reduces the weight and cost of the child seat 100a.

[0196] Alternatively, the shape of the slide groove 113 is set to be arc-shaped so that the seat body 11 slides along the arc-shaped slide track relative to the base 12. As described above, one end of the bracket 414 is pivotally connected to the base 12 by a pivot pin 415 such that the direction of movement of the drive block 413 coincides with the direction of the shape of the slide groove 113. While the drive block 413 is pressing the drive rod 114, the drive block 413 swings together with the bracket 414 around the pivot point and pivot member 13 of the bracket 414, adapting to the sliding of the seat body 11 relative to the pivot member 13.

[0197] The operating principle of the child seat 100a in one embodiment of this application will be described in detail below with reference to Figures 17 to 19 and Figures 21 to 25.

[0198] As shown in Figure 17, the angle of the seat body 11 is, for example, in an upright position. In this case, the drive block 413 is, for example, in the upper limit position. In this case, the user (for example, the driver or passenger operating the vehicle) sends a command to the control mechanism 42 to adjust the seat (tilt) angle by pressing a control button provided on the remote control device 432 (described below) or on the operation panel 431. After receiving the command to adjust the seat angle, the control mechanism 42 controls the motor 411 of the drive mechanism 41 to rotate. The motor 411 drives a screw 412 to rotate, and the rotation of the screw 412 drives the drive block 413 to move from the upper limit position to the lower limit position. The movement of the drive block 413 is transmitted to the seat body 11 by the cooperation of the drive rod 114 and the connection hole 4131, thereby causing the seat body 11 to have a tendency to move. The movement of the seat body 11 is achieved as a slide of the seat body 11 relative to the base 12 through the cooperation between the slide rod 131 and the arc-shaped slide groove 113. As the seat body 11 slides relative to the base 12, the bracket 414 pivots relative to the base 12 or the rotating member 13 and adapts to the shape of the slide groove 113. Thus, the angle of the seat body 11 gradually switches from the upright position shown in Figure 2 to the reclined position shown in Figure 3, and vice versa. Therefore, the driver or passenger operating the vehicle can easily adjust the angle of the child seat 100a provided in the embodiment of this application.

[0199] Referring to Figures 20 and 28, in one embodiment, as described above, the rotating member 13 is provided with a circular rotating connector 132. The rotating connector 132 is fixed to, for example, the base 12 and pivotally connected to the rotating member 13. In some embodiments, there is a gap between the rotating connector 132 and the rotating member 13, and the upper housing of the base 12 is rotatably held in the gap. The rotating member 13 is rotatably disposed on the base 12 by the rotating connecting member 132. The edge of the rotating connecting member 132 has an annular flange, which is slidably fitted into an annular groove in the upper housing of the base. As described above, the rotating connector 132 is further provided with an electrical slip ring 133, which is configured to maintain an electrical connection between the components disposed on the sheet body 11 and the components disposed on the base 12 when the sheet body 11 rotates.

[0200] Referring to Figures 16 and 28, in one embodiment, the child seat 100a further includes an operating mechanism 43. The operating mechanism 43 includes an operating panel 431 disposed on the base 12 and is electrically connected to a control mechanism 42. The operating panel 431 includes control buttons 433 configured to adjust the (tilt) angle of the seat body 11. The user can change the angle of the seat body 11 by operating the tilt position control buttons on the operating panel 431 to control the activation of the drive mechanism 41 via the control mechanism 42, thereby controlling the seat body 11 to slide relative to the base 12.

[0201] Alternatively, in one embodiment, the control button 433 may include a toggle button 4331 and a tilt angle button configured to control the tilt angle of the seat body 11. After the toggle button 4331 is pressed, the tilt angle of the seat body 11 can be adjusted by pressing the tilt reduction button or the tilt increase button of the control button 433. In some embodiments, the control button may be replaced by a touchscreen, remote control, mobile phone application, etc.

[0202] Referring to Figures 21 and 26, in one embodiment, the control mechanism 42 includes a sheet circuit board 421, a mounting box 422, and a mounting cover 423. The mounting box 422 is disposed on the sheet body 11, the sheet circuit board 421 is disposed in the mounting box 422, and the mounting cover 423 covers the mounting box 422, allowing the mounting box 422 to be closed.

[0203] Referring to Figures 28 and 34, in one embodiment, the sheet circuit board 421 is electrically connected to the electrical slip ring 133, the drive mechanism 41, and the position sensor 4141. The operation panel 431 and the base circuit board 124 are electrically connected to the electrical slip ring 133, so that the control mechanism 42 can be electrically connected to other components. Alternatively, electrical connections can be achieved by using wire connections. In this application, the term “electrical connection” includes connections used to transmit electrical energy and connections used to transmit electrical signals.

[0204] Referring to Figures 30 to 33, in one embodiment, the child seat 100a may further include a remote control device 432. The remote control device 432 can establish a wireless communication connection to a control mechanism 42, such as via radio frequency or Bluetooth, and can transmit control signals to the control mechanism 42, which in turn can control a drive mechanism 41 to drive the seat body 11 to slide relative to the base 12, thereby changing the tilt angle of the seat body 11.

[0205] Alternatively, the remote control device 432 may be a remote control, which is wirelessly and communicatively connected to the control mechanism 42. For example, the remote control includes an upper cover 4321 and a lower cover 4322 that are detachably fastened to each other, and a battery 4323. Alternatively, the upper cover 4321 and the lower cover 4322 are fastened to each other using a first protrusion 4327 disposed on the upper cover 4321 and a second protrusion 4326 disposed on the lower cover 4322. Alternatively, the upper cover 4321 and the lower cover 4322 may also be fastened to each other in another suitable manner, such as bolted or magnetic connections, which are not limited herein.

[0206] Alternatively, referring to Figure 31, a removal port 4325 is further provided on the remote control to separate the upper cover 4321 and the lower cover 4322, which are attached to each other. Referring to Figures 32 and 33, a housing space 4324 is defined between the upper cover 4321 and the lower cover 4322, and a replaceable battery 4323 is housed in the housing space 4324. Alternatively, a control button for switching between upright mode and reclining mode is provided on the remote control.

[0207] Referring to Figures 28 and 34, one embodiment of the present application further provides a child seat 100a including a base 12 and a seat body 11. The base 12 includes a rotating member 13 and a rotating connector 132. The rotating connector 132 is fixedly connected to the main body of the base 12 (not shown in the figures, used as a main body structure on a vehicle seat) and may be pivotally connected to the rotating member 13 so that the rotating member 13 can rotate relative to the main body of the base 12. The seat body 11 is slidably connected to the rotating member 13, and the tilt angle of the seat body 11 relative to the base 12 changes as the seat body 11 slides relative to the rotating member 13. More specifically, the tilt angle of the seat body 11 relative to the base 12 may also be referred to as the tilt angle of the seat body 11 relative to the rotating member 13.

[0208] Referring to Figure 16, in some embodiments, a power input port 126 may be located on the base 12, and the power input port 126 may be connected to, for example, a vehicle power supply. The power supply system (e.g., vehicle power supply) supplies power to the child seat 100a via the power input port 126.

[0209] As described above, a base circuit board 124 is provided on the base 12, and a sheet circuit board 421 is provided on the sheet body. An electrical slip ring 133 is provided on the rotary connector 132. The base circuit board 124 is electrically connected to the sheet circuit board 421 via the electrical slip ring 133. Specifically, referring to Figure 35, the base circuit board 124 is electrically connected to the electrical slip ring 133, for example, via a first wire 124a. The electrical slip ring 133 is electrically connected to the sheet circuit board 421, for example, via a second wire 133a. The sheet circuit board 421 is electrically connected to the drive mechanism 41, for example, via a third wire 421a. The power input port 126 may also be electrically connected to the base circuit board 124, that is, the power supply system is electrically connected to the base circuit board 124.

[0210] As described above, the drive mechanism 41 includes a motor 411 and a plurality of position sensors 4141, and the seat circuit board 421 is configured to control the motor 411 to drive the motor 411 to move or to stop the movement in response to signals from the position sensors 4141. The base circuit board 124 is configured to supply power to the seat circuit board 421 and to send control signals used to control the (tilt) angle adjustment of the seat. For specific structures of the drive mechanism 41, seat circuit board 421, and base circuit board 124, refer to the drive mechanism 41, control mechanism 42, and operating mechanism 43 in other embodiments of this application.

[0211] By providing the sheet circuit board 421, the base circuit board 124, and the electric slide ring 133, in one embodiment, the pivoting and sliding of the sheet body 11 does not affect the wires between the electric slide ring 133 and the base circuit board 124, and the stability of the electrical connection between the slide ring 2014 and the base circuit board 124 can be ensured. On the other hand, when the sheet body 11 pivots and slides, the wires between the sheet circuit board 421 and the electric slip ring 133 are less likely to become entangled.

[0212] Generally, in a child car seat, electronic components such as motors, sensors, fans, and heating nets are typically located on the seat body, while the power input port 126 and button panel are typically located on the base of the child car seat. The electronic components and power input port are connected to a control circuit board formed by a microcontroller and its peripheral circuits, which is typically located on the base of the child car seat. There are 6 to 8 electrically connected wires between electronic components such as motors or sensors and the control circuit board, and at least 6 electrically connected wires between electronic components such as fans or heating devices and the control circuit board. Therefore, a harness containing 6 to 15 wires needs to pass between the base 12 and the seat body 11. When the seat body 11 rotates 360 degrees relative to the base, or when the tilt angle of the seat body 11 is adjusted, the harness is pulled, making it easy for the wires to become entangled or for the wires to interfere with the movable mechanical structure within the child car seat housing.

[0213] In this embodiment, the sheet body 11 and the base 12 are each provided with a circuit board, namely a base circuit board 124 and a sheet circuit board 421. The base circuit board 124 is configured to connect a power input port and control buttons, and the sheet circuit board 421 is configured to control electronic components such as motors. Only two to three power and control wires are routed between the sheet circuit board 421 and the base circuit board 124 via an electrical slip ring 133, thereby effectively reducing wire entanglement and interference. For example, a remote control device 432 may be wirelessly connected to the base circuit board 124 or the sheet circuit board 421 to control the operation of the motor 411.

[0214] Referring to Figure 35, in one embodiment, the seat body 11 includes a backrest portion 1103 and a seat portion 1104, with the backrest portion 1103 connected to the seat portion 1104. In some embodiments, the intermediate portion between the backrest portion 1103 and the seat portion 1104 is a curved surface of approximately 90 degrees. In some embodiments, the backrest portion 1103 and the seat portion 1104 together form a substantially L-shaped structure. The seat circuit board 421 is disposed, for example, at the connection between the backrest portion 1103 and the seat portion 1104. A cavity is formed between the seat circuit board 421 and the rotating member 13, and the second wire 133a between the electrical slip ring 133 and the seat circuit board 421 is suspended within the cavity.

[0215] When the sheet body 11 and the rotating member 13 rotate relative to the base 12, the first wire 124a between the electrical slip ring 133 and the base circuit board 124 and the third wire 421a between the sheet circuit board 421 and the drive mechanism 30 do not move due to force. One end of the second wire 133a, which is connected to the sheet body 11 and between the electrical slip ring 133 and the sheet circuit board 421, rotates due to the circumferential force applied in the rotational direction by the sheet body 11, and the other end, which is connected to the electrical slip 133, drives the electrical slip ring 133 to rotate.

[0216] When the seat body 11 slides back and forth relative to the base 12, the first wire 124a does not move due to force. When the seat body 11 slides to its furthest forward position relative to the base 12, that is, when the seat body 11 is in the position with the maximum tilt angle, as shown in Figure 35, the distance between the electrical slip ring 133 and the seat circuit board 421 (the intermediate portion between the backrest portion 1103 and the seat portion 1104) becomes the minimum, the second wire 133a becomes relatively loosened. On the other hand, the distance between the seat circuit board 421 and the rotating member becomes the maximum, and the third wire 421a becomes relatively taut. When the seat body 11 slides to its final position relative to the base 12, that is, when the seat body 11 is in the position with the minimum tilt angle, the distance between the electrical slip ring 133 and the seat circuit board 421 (the intermediate portion between the backrest portion 1103 and the seat portion 1104) is at its maximum, so the second wire 133a is relatively taut. On the other hand, the distance from the seat circuit board 421 to the rotating member is at its minimum, so the third wire 421a is relatively slack. Therefore, during rotation or forward / backward sliding of the seat body 11, the second wire 133a and the third wire 421a are unlikely to interfere with each other. The cavity provides a dwelling space for the second wire 133a, which is in a relatively slack state, to prevent the wire from being twisted or caught on other elements in the child seat due to deformation.

[0217] Referring to Figure 35, in one embodiment, the electrical slip ring 133 is configured such that, during the sliding of the seat body 11 relative to the base 12, the extension of the axis of the electrical slip ring 133 always intersects with the seat portion 1104 of the seat body 11. This restricts the pulling direction and deformation amplitude of the wire between the electrical slip ring 133 and the seat circuit board 421 as the seat body slides, preventing the wire from becoming entangled around the seat circuit board 421, the electrical slip ring 133, or other components within the child seat.

[0218] Alternatively, the seat circuit board 421 is configured such that, during the sliding of the seat circuit board 421 relative to the base 12, the projection of the seat circuit board 421 on the base 12 always covers the electrical slip ring 133. This further restricts the direction of tension and deformation amplitude of the wires between the electrical slip ring 133 and the seat circuit board 421 as the seat body 11 slides, preventing the wires from becoming entangled around the seat circuit board 421, the electrical slip ring 133, or other components within the child seat.

[0219] Referring to Figure 35, in this embodiment, as described above, the drive mechanism 41 is disposed on the rotating member 13 and extends toward the backrest portion 1103 of the seat body 11. The seat circuit board 421 is electrically connected to the drive mechanism 41, for example, via a third wire 421a. The drive mechanism 41 is disposed on the rotating member 13. The seat circuit board 421 slides with the seat body 11, and the drive mechanism 41 pivots with the sliding of the seat body 11 to prevent entanglement of wires between the drive mechanism 41 and the seat circuit board 421. Furthermore, the drive mechanism 41 is positioned outside the range that the second wire 133a between the electrical slip ring 133 and the seat circuit board 421 can reach. Therefore, the second wire 133a between the electrical slip ring 133 and the seat circuit board 421 is not wrapped around the drive mechanism 41.

[0220] The implementation of this embodiment for adjusting the tilt angle of the seat body can also be applied to the first, second, and fourth embodiments.

[0221] Fourth Embodiment

[0222] A fourth embodiment of this application provides a child carrier, which may be, for example, a child seat 100a, a child cart, etc. In the following description, the child seat 100a will be taken as an example of a child carrier. Where there is no contradiction, the structure of the child seat 100a provided in this fourth embodiment may refer to the child seats described in the preceding embodiments.

[0223] Child seat 100a may be fastened to a vehicle seat using its own ISOFIX connectors and pull-up belts (also called top straps), or it may be fastened to a vehicle seat using the vehicle's seat belts. Child seat 100a may be mounted facing forward or facing rearward in a vehicle seat. When child seat 100a is mounted facing forward in a vehicle seat, it is generally applicable to older children. For younger children, child seat 100a generally needs to be mounted facing rearward in a vehicle seat for use.

[0224] Figures 36 to 40 are schematic diagrams of the child seat 100a according to the fourth embodiment of this application. Figure 36 shows a perspective view of the child seat 100a. Figure 37 shows a side view of the child seat 100a of Figure 36 when the seat assembly 500 is in the forward-facing position. Figure 38 shows a side view of the child seat 100a of Figure 36 when the seat assembly 500 is in the rear-facing position. Figure 39 shows a cross-sectional view of the child seat 100a of Figure 36 taken along U1-U1 when the seat assembly 500 is in the forward-facing position. Figure 40 shows a cross-sectional view of the child seat 100 of Figure 36 taken along U1-U1 when the seat assembly 500 is in the rear-facing position.

[0225] As shown in Figures 36 to 38, the child seat 100a includes a base assembly 600 and a seat assembly 500 rotatably mounted on the base assembly 600. The seat assembly 500 includes a seat body 510. A mounting seat 520 is provided at the bottom of the seat body 510. In some embodiments, the seat body 510 is non-removably connected to the mounting seat 120. In some alternative embodiments, the mounting seat 520 is detachably connected to the seat body 510 (not shown), and this is not limited herein. The mounting seat 520 rotates relative to the base assembly 600 about a pivot axis X3-X3, thereby driving the seat body 510 mounted thereon to rotate about the pivot axis X3-X3, thereby allowing the seat body 510 to switch between a forward-facing and a rear-facing position.

[0226] Child seat 100a may be further provided with a misuse prevention structure 700, which is configured to prevent improper forward-facing installation of child seat 100a. Specifically, the misuse prevention structure 700 is configured to prevent the seat assembly 500 of child seat 100a from being accidentally locked in the forward-facing position when a younger group of children are seated in child seat 100a. Note that when the seat assembly 500 is positioned or locked in the "forward-facing position," it means that the seat assembly 500 is in the forward-facing position, facing away from the backrest of the vehicle seat, and the child seated in the seat assembly 500 is facing forward in the vehicle. When the seat assembly 500 is positioned or locked in the "rear-facing use position," it means that the seat assembly 500 is in the rear-facing use position, facing the backrest of the vehicle seat, and the child seated in the seat assembly 500 is facing the rear of the vehicle.

[0227] In some embodiments, the mounting seat 520 is formed, for example, as part of the seat assembly 500. Referring to Figures 39 and 40, for example, a accommodating space 501 is formed between the seat body 510 and the mounting seat 520. In some embodiments, the mounting seat 520 and the seat body 510 may be connected in a relative slidable manner, for example, so that the tilt angle of the seat body 510 can be adjusted. For a sliding connection structure between the mounting seat 520 and the seat body 510, refer to the sliding connection structure between the mounting seat 13 and the seat body 11 in the third embodiment described above.

[0228] In some alternative embodiments, the seat assembly 500 is detachably connected to, for example, a mounting seat 520 (not shown), which is rotatably mounted on a base assembly 600 and forms part of the base assembly 600, and this is not limited herein.

[0229] Unless otherwise specified and limited, terms describing directions such as “front,” “back,” “top,” “bottom,” “left,” and “right” in embodiments of the child seat 100a of this application are based on the front, rear, upper, lower, left, and right orientations of the child seat 100a when it is mounted facing forward on the vehicle seat and the vehicle is in normal operation. In the figures, arrows L and R are used to indicate “left” and “right,” and arrows F and B are used to indicate “front” and “back.” These terms describing directions are used solely to clarify the description of embodiments of this application and are not intended to improperly limit the scope of protection of this application. Since the seat assembly 500 of the child seat 100a has a forward-facing use position and a rearward-facing use position, it will be understood that the front, rear, left, and right orientations of the seat assembly 500 may vary depending on the position in which the seat assembly 500 is used. Specifically, when the seat assembly 500 is in the forward-facing position, the front-rear and left-right orientations of the seat assembly 500, the front-rear and left-right orientations of the base assembly 600, and the front-rear and left-right orientations of the vehicle are all in agreement. When the seat assembly 500 is in the rear-facing position, the front-rear and left-right orientations of the base assembly 600 are in agreement with the front-rear and left-right orientations of the vehicle, while the front-rear and left-right orientations of the seat assembly 500 are opposite to the front-rear and left-right orientations of the vehicle.

[0230] Referring to Figures 39 and 40, the base assembly 600 includes a base body 610, which includes a first housing 611 and a second housing 612, the first housing 611 and the second housing 612 combined to form a housing space 618. The second housing 612 forms the bottom surface of the base body 610. The bottom surface of the base body 610 is, for example, flat so that it rests on a vehicle seat. The first housing 611 is provided with a retaining recess 613, and the mounting seat 520 is provided with a retaining projection 521. The cross-section of the retaining projection 521 is substantially circular. The retaining projection 521 is at least partially housed within the retaining recess 613 and defines the axis of rotation X3-X3 of the seat assembly 500 relative to the base assembly 600.

[0231] As shown in Figures 39 and 40, in some embodiments, the child seat 100a further includes an engagement mechanism 810 disposed between the base assembly 600 and the seat assembly 500, the engagement mechanism 810 being configured to selectively lock the seat assembly 500 into a forward-facing or rearward-facing position.

[0232] In some embodiments, the engagement mechanism 810 includes an engagement pin 8110, a first engagement hole 8121, a second engagement hole 8122, and an engagement reset member 8130. The engagement pin 8110 is movably disposed in the seat assembly 500 and has an engagement position and a release position. In the engagement position, the engagement pin 8110 protrudes from the surface of the retaining projection 521. In the release position, the engagement pin 8110 retracts, for example, from the surface of the retaining projection 521 and is housed inside the surface of the retaining projection 521. The engagement reset member 8130 includes, for example, a spring disposed between the engagement pin 8110 and the seat assembly 500. The spring biases the engagement pin 8110 to move toward the engagement position; that is, the spring provides a force for the engagement pin 8110 to move toward the engagement position. The engaging pin 8110 can further cooperate with an operating member (not shown) disposed on the seat assembly 500, so that the operating member can drive the engaging pin 8110 and move it toward the release position.

[0233] When the seat assembly 500 is not rotated to the forward or backward use position, the engagement pin 8110 is in the released position under pressure from the inner circumferential surface of the retaining recess 613. When the seat assembly 500 is rotated to the forward or backward use position, the engagement pin 8110 protrudes from the surface of the retaining projection 521 into the first engagement hole 8121 or the second engagement hole 8122, thereby moving to the engagement position and locking the seat assembly 500 into the corresponding forward or backward use position. Specifically, referring to Figure 39, when the engagement pin 8110 is in the engagement position and engages with the first engagement hole 8121, the seat assembly 500 is locked into the forward use position. Referring to Figure 40, when the engagement pin 8110 is in the engagement position and engages with the second engagement hole 8122, the seat assembly 500 is locked into the backward use position. When the engagement pin 8110 is in the released position, the engagement pin 8110 disengages the first engagement hole 8121 and the second engagement hole 8122, allowing the seat assembly 500 to rotate relative to the base assembly 600.

[0234] Referring to Figure 46, a restricting wall is formed on the wall of the retaining recess 613, and the restricting wall may be the inner circumferential surface (also referred to as the inner surface or side wall) or the bottom surface of the retaining recess 613. In this embodiment, the restricting wall is the side wall of the retaining recess 613, i.e., the inner circumferential surface of the retaining recess 613. In some alternative embodiments, the restricting wall may be the bottom surface of the retaining recess 613, and this is not limited herein.

[0235] In some embodiments, both the first engagement hole 8121 and the second engagement hole 8122 are located in the first housing 611 and penetrate the regulating wall of the retaining recess 613, thereby enabling the retaining recess 613 to communicate with the housing space 618. That is, the first engagement hole 8121 and the second engagement hole 8122 are located on the inner circumferential surface of the retaining recess 613. The first engagement hole 8121 and the second engagement hole 8122 each extend radially through the retaining recess 613. In some alternative embodiments, the first engagement hole 8121 and the second engagement hole 8122 are located on the bottom surface of the retaining recess 613. The first engagement hole 8121 and the second engagement hole 8122 extend, for example, axially through the retaining recess 613.

[0236] Referring to Figures 39 and 40, one of the first engagement hole 8121 and the second engagement hole 8122 is located at the front of the base assembly 600, and the other of the first engagement hole 8121 and the second engagement hole 8122 is located at the rear of the base assembly 600. Note that the front of the base assembly 600 refers to the portion of the base assembly 600 located in front of the rotation axis X3-X3, that is, the portion of the base body 610 located in front of the rotation axis X3-X3. The rear of the base assembly 600 refers to the portion of the base assembly 600 located behind the rotation axis X3-X3. The base assembly 600 further has a left portion on the left side of the rotation axis X3-X3 and a right portion on the right side of the rotation axis X3-X3.

[0237] Therefore, as an example, when the seat assembly 500 is in the forward-facing use position, the seat assembly 500 has a front part located in front of the rotation axis X3-X3, a rear part located behind the rotation axis X3-X3, a right part located to the right of the rotation axis X3-X3, and a left part located to the left of the rotation axis X3-X3. When the seat assembly 500 is in the rearward-facing use position, it should be understood that the left-right orientation of the seat assembly 500 is the opposite of the left-right orientation of the seat assembly 500 when the seat assembly 500 is in the forward-facing use position.

[0238] As shown in Figures 39 and 40, in this embodiment, the first engagement hole 8121 is located at the rear of the base assembly 600, and the second engagement hole 8122 is located at the front of the base assembly 600. The engagement pin 8110 is located at the rear of the seat assembly 500. In some alternative embodiments, the first engagement hole 8121 is located at the front of the base assembly 600, the second engagement hole 8122 is located at the rear of the base assembly 600, and the engagement pin 8110 is located at the front of the seat assembly 500.

[0239] Referring to Figures 39 and 40, the puncture port 502 is disposed on the mounting seat 520, and the engagement pin 8110 is slidably disposed in the housing space 501 and can extend at least partially from the mounting seat 520 through the puncture port 502 to selectively engage with either the first engagement hole 8121 or the second engagement hole 8122, thereby allowing the seat assembly 500 to be locked in a forward-facing or rearward-facing position. More specifically, the engagement pin 8110 is slidably disposed on the mounting seat 520 by using an engagement locking seat 540. The engagement locking seat 540 is disposed in the housing space 501. A first housing groove 541 is formed between the engagement locking seat 540 and the mounting seat 520, and a first restricting portion 542 is disposed in the first housing groove 541. The first housing groove 541 is connected to the engagement puncture port 502. The engaging pin 8110 is in pin form and is disposed with a second restricting portion 8111. The engaging pin 8110 is disposed in the first housing groove 541 and is at least partially positioned in the first housing groove 541 by bringing the second restricting portion 8111 into contact with the first restricting portion 542. This allows the movement stroke of the engaging pin 8110 to be restricted, thereby allowing the engaging pin 8110 to extend into the first engaging hole 8121 or the second engaging hole 8122 by using the engaging puncture port 502.

[0240] The engagement reset member 8130 is disposed in the first housing groove 541. For example, the engagement reset member 8130 is a pressure spring. One end of the engagement reset member 8130 abuts against the end of the first housing groove 541, and the other end of the engagement reset member 8130 is sleeve-mounted on the engagement pin 8110 and abuts against the second restricting portion 8111. The engagement reset member 8130 is suitable for biasing the engagement pin 8110 so that it can move toward the engagement position. As a result, when the engaging pin 8110 is not blocked by the side wall of the retaining recess 613, the engaging pin 8110 can automatically move to the engaged position under the elastic restoring force of the engaging reset member 8130. Therefore, when the seat assembly 500 rotates to a predetermined position (for example, to the rearward or forward-facing use position), the engaging pin 8110 can automatically extend into the first engaging hole 8121 or the second engaging hole 8122 under the elastic restoring force of the engaging reset member 8130 (for example, a pressure spring), and automatically lock the seat assembly 500 in the corresponding position.

[0241] The engagement pin 8110 may be driven to the released position by using any suitable release mechanism (not shown), that is, the engagement pin 8110 may be released by using any suitable release mechanism. Specifically, when the release mechanism is activated, it drives the engagement pin 8110 to move to the released position in order to allow rotation of the seat assembly 500. When the release mechanism is not activated, the engagement pin 8110 moves to the engaged position under the elastic restoring force of the engagement reset member 8130, so that when the seat assembly 500 rotates to a predetermined position (for example, to the rearward use position or the forward use position), the engagement pin 8110 automatically engages with the first engagement hole 8121 or the second engagement hole 8122 under the elastic restoring force of the engagement reset member 8130.

[0242] From the above, it can be seen that the misuse prevention structure 700 is further disposed between the base assembly 600 and the seat assembly 500. The misuse prevention structure 700 has an ON state and an OFF state. When the misuse prevention structure 700 is in the ON state (i.e., the misuse prevention function of the misuse prevention structure 700 is activated), the misuse prevention structure 700 restricts the seat assembly 500 from a predetermined lateral position to a forward-facing use position and allows the seat assembly 500 to move from a lateral position to a rearward-facing use position. When the misuse prevention structure 700 is in the OFF state (i.e., the misuse prevention function of the misuse prevention structure 700 is not activated), the seat assembly 500 can rotate freely around the rotation axis X3-X3 relative to the base assembly 600. By installing the misuse prevention structure 700, the rotation of the seat assembly 500 within a predetermined rotation stroke can be restricted, thereby preventing the seat assembly 500 from being accidentally rotated and locked in the forward-facing position, and preventing younger children from being accidentally seated in the forward-facing child seat 100a.

[0243] Referring to Figures 41 to 43 and Figure 46, in some embodiments, the misuse prevention structure 700 includes a regulating member 710, a regulating groove 720, an operating assembly, and a regulating reset member 750. Referring to Figure 46, the regulating groove 720 is disposed on the base assembly 600. The regulating groove 720 extends around the rotation axis X3-X3, and one end (front end) of the regulating groove 720 is provided with a locking portion 721, and the other end (rear end) of the regulating groove 720 is provided with a guide surface 722. The guide surface 722 is an inclined surface or arcuate surface extending from the bottom of the regulating groove 720 to the opening of the regulating groove 720. The regulating member 710 is movably disposed on the mounting seat 520 and is movable between a locked position and an unlocked position.

[0244] Referring to Figures 41, 42, and 46, the restricting member 710 is located in front of the mounting seat 520, and the restricting groove 720 is located on the side of the base assembly 600. When the restricting member 710 is in the locked position (i.e., the restricting member 710 is locked in the restricting groove 720), the restricting member 710 extends into the restricting groove 720 to position the seat assembly 500 in a predetermined lateral position corresponding to the restricting groove 720, which is located between the forward-facing use position and the rearward-facing use position. In this case, the restricting member 710 is locked by the locking portion 721, thereby restricting the seat assembly 500 from the lateral position to the forward-facing use position relative to the base assembly 600, i.e., restricting the seat assembly 500 from rotating toward the locking portion 721 relative to the base assembly 600. The guide surface 722 is located at the other end of the restricting groove 720, so that the rotation of the seat assembly 500 from the lateral position to the rearward-facing use position is not restricted. Specifically, the restricting member 710 exits the restricting groove 720 via the guide surface 722, thereby enabling the seat assembly 500 to rotate from a lateral position to a rearward-facing position, that is, the seat assembly 500 to rotate toward the guide surface 722. In other words, when the restricting member 710 is inserted into the restricting groove 720, the seat assembly 500 is locked (also called half-locked) in one direction in the lateral position corresponding to the restricting groove 720. When the restricting member 710 is in the unlocked position, the restricting member 710 is detached from the restricting groove 720 and does not interfere with the restricting groove 720, allowing for angle adjustment of the seat assembly 500 relative to the base assembly 600.

[0245] When the seat assembly 500 is locked in one direction in the lateral position, the regulating groove 720 generates a certain resistance against the regulating member 710, thereby holding the seat assembly 500 in the lateral position. This makes it easy for a child to enter and exit the child seat 100a from the side. When a larger child is seated, the regulating member 710 needs to be released, and the seat assembly 500 is rotated to the forward-facing position. When a smaller infant is placed in the seat assembly 500, there is no need to release the regulating member 710, and the seat assembly 500 only needs to be forced to rotate in the direction of the guide surface 722 (i.e., the rearward-facing direction), thereby allowing the seat assembly 500 to exit the regulating groove 720 and thereby disengage the seat assembly 500 from the lateral position. The cooperation between the regulating member 710 and the regulating groove 720 adds an obstacle to moving the seat assembly 500 to the forward-facing use position when a smaller-sized infant is seated, thereby effectively preventing the seat assembly 500 from accidentally rotating to the forward-facing use position when a smaller-sized infant is seated.

[0246] The predetermined lateral position can be any angular position between the forward-facing use position and the rear-facing use position. Specifically, when the seat assembly 500 is in the forward-facing use position, the relative angle between the seat assembly 500 and the base assembly 600 is considered to be 0 degrees or 360 degrees. When the seat assembly 500 is in the rear-facing use position, the relative angle between the seat assembly 500 and the base assembly 600 is considered to be 180 degrees, and the predetermined lateral position can be when the relative angle between the seat assembly 500 and the base assembly 600 is greater than 0 degrees and less than 180 degrees, and / or when the relative angle between the seat assembly 500 and the base assembly 600 is greater than 180 degrees and less than 360 degrees.

[0247] Referring to Figure 46, the restricting member 710 faces the restricting wall of the retaining recess 613. From the above, it can be seen that the restricting wall can be the inner circumferential surface or the bottom surface of the retaining recess 613. In this embodiment, the restricting member 710 faces the inner circumferential surface of the retaining recess 613, i.e., the inner circumferential surface of the retaining recess 213 is used as the restricting wall. In some alternative embodiments, the restricting member 710 can face the bottom surface of the retaining recess 613, i.e., the bottom surface of the retaining recess 213 is used as the restricting wall, and this is not limited herein.

[0248] Referring to Figure 46, in some embodiments, the restricting groove 720 is positioned on the restricting wall of the retaining recess 613 and is recessed relative to the restricting wall of the retaining recess 613. The locking portion 721 is substantially perpendicular to the bottom wall of the restricting groove 720, the angle between the guide surface 722 and the bottom wall of the restricting groove 720 is obtuse, and the two sides of the guide surface 722 are connected to the bottom wall of the restricting groove 720 and the restricting wall of the retaining recess 613 (more specifically, the inner circumferential surface), respectively.

[0249] In some embodiments, there are two regulating grooves 720, which are symmetrically distributed on the left and right sides of the base assembly 600 (more specifically, the base body 610), respectively. The predetermined lateral positions include, for example, a left position facing left towards the seat assembly 500 (i.e., the relative angle between the seat assembly 500 and the base assembly 600 is approximately 90 degrees) and a right position facing right towards the seat assembly 500 (i.e., the relative angle between the seat assembly 500 and the base assembly 600 is approximately 270 degrees).

[0250] In some embodiments, the direction of the line between the regulating groove 720 and the rotation axis X3-X3 of the seat assembly 500 is substantially perpendicular to the longitudinal direction such that the seat assembly 500 is restricted to a predetermined lateral position perpendicular to the longitudinal direction when the regulating member is inserted into the regulating groove 720. The angle between the predetermined lateral position and its adjacent forward or rearward use position is approximately 90 degrees.

[0251] Referring to Figure 46, the retaining recess 613 may further include a resistance surface 760, a second engagement hole 8122, and a first engagement hole 8121 (not shown in Figure 46, opposite the second engagement hole 8122). The two resistance surfaces 760 are located on the left and right sides of the retaining recess 613, respectively. The two resistance surfaces 760 are located, for example, above two regulating grooves 720. In some embodiments, the length of the inner circumference of each resistance surface 760 along the retaining recess 613 is approximately 5 cm to 15 cm. Each resistance surface 760 may be formed by a series of longitudinally arranged grooves. The width of each groove is smaller than the width of the engagement pin 8110 to avoid locking of the engagement pin 8110 in the resistance surface 760. When the seat assembly 500 rotates near the lateral position relative to the base assembly 600, the engagement pin 8110 contacts the resistance surface 760, thereby increasing the resistance of the seat assembly 500 in the rotational direction relative to the base assembly 600, thereby making the user aware that the seat assembly 500 is in the lateral position, and the cooperation between the engagement pin 8110 and the resistance surface 760 also helps to maintain the seat assembly 500 in the lateral position.

[0252] The first engagement hole 8121 and the second engagement hole 8122 are located in front of and behind the retaining recess 613, respectively. As described above, the engagement pin 8110 is configured to lock the seat assembly 500 in a forward-facing or rearward-facing position by selectively cooperating with the first engagement hole 8121 or the second engagement hole 8122. In some embodiments, the first engagement hole 8121 and the second engagement hole 8122, the regulating groove 720, and the resistance surface 760 are located on the inner circumferential surface of the retaining recess 613, and the first engagement hole 8121, the second engagement hole 8122, and the resistance surface 760 are located at a higher height than the regulating groove 720.

[0253] As shown in Figures 39, 40, and 43, the engaging pin 8110 is located behind the outer circumferential surface of the retaining projection 521 of the seat assembly 500, and the regulating member 710 is located in front of the outer circumferential surface of the retaining projection 521. The wire connecting the engaging pin 8110 and the regulating member 710 passes, for example, through the rotation axis X3-X3 of the seat assembly 500. The height of the engaging pin 8110 is greater than that of the regulating member 710 to avoid interference with each other. In addition, as shown in Figure 42, the retaining projection 521 is provided with flange portions 770 below the engaging pin 8110 and the regulating member 710, respectively, to avoid damage to the engaging pin 8110 and the regulating member 710 when the seat assembly 500 is shaking.

[0254] As shown in Figures 41 to 44, the restricting member 710 includes a restricting body 711 and a drive projection 712. The restricting body 711 is slidably disposed on the mounting seat 520. The restricting body 711 includes a restricting end 713, which is configured to cooperate with the restricting groove 720. The mounting seat 520 is provided with a sliding groove 522 and a restricting passage exit 523 connected to the sliding groove 522. The restricting body 711 is slidably disposed in the sliding groove 522. The restricting body 711 extends into or exits the restricting groove 720 through the restricting passage exit 523. The drive projection 712 protrudes from the restricting body 711 in a direction parallel to the rotation axis X3-X3 of the mounting seat 520, and the drive projection 712 is pressed by the operating assembly 730 to drive and move the restricting body 711. In this embodiment, the restricting member 710 is disposed on the retaining projection 521. When the restricting member 710 is in the locked position, the restricting end 713 of the restricting member 710 protrudes from the retaining projection 521 and locks in the restricting groove 720. When the restricting member 710 is in the unlocked position, the restricting end 713 of the restricting member 710 is returned to the retaining projection 521.

[0255] In some alternative embodiments, the outer surface (more specifically, the outer peripheral surface) or bottom surface of the retaining projection 521 is formed as a restricting wall, and the restricting groove 720 is disposed on the retaining projection 521 and recessed relative to the restricting wall of the retaining projection. The two ends of the restricting groove 720 are provided with restricting ends 721 and guide surfaces 722, respectively. A locking portion 721 is provided at one end (more specifically, the front end) of the restricting groove 720, and a guide surface 722 is provided at the other end (more specifically, the rear end) of the restricting groove 720. The angle between the guide surface 722 and the bottom wall of the restricting groove 720 is obtuse, and the two sides of the guide surface 722 are connected to the bottom wall and the restricting wall of the restricting groove 720, respectively. There are two restricting grooves 720, which are distributed symmetrically on the left and right sides of the retaining projection 521 of the sheet assembly 500, respectively. The restricting member 710 is disposed in the retaining recess 613 and has a restricting end 713. When the restricting member 710 is in the locked position, the restricting end 713 of the restricting member 710 extends into the retaining projection 521 and locks in the restricting groove 720. When the restricting member 710 is in the unlocked position, the restricting end 713 of the restricting member 710 extends out of the retaining projection 521.

[0256] Referring to Figures 42 and 43, in some embodiments, flange portions 770 may be formed in front of and / or behind the outer surface of the retaining projection 521, the flange portions 770 being located at the lower end of the outer surface of the retaining projection 521 and below the regulating member 710 and / or the engaging pin 8110. When the seat assembly 500 is positioned in the forward-facing or rearward-facing position, the front flange portion and / or the rear flange portion 770 engage with the front reinforcing plate 851 and / or the rear reinforcing plate 852, respectively, as will be described later, thereby increasing the connection strength between the seat assembly 500 and the base assembly 600 in the forward-facing and rearward-facing positions.

[0257] As shown in Figures 43 and 44, in some embodiments, a restrictor reset member 750 is disposed between the restrictor member 710 and the mounting seat 520, and the restrictor reset member 750 biases the restrictor member 710 to move toward the locked position. Specifically, as described above, the mounting seat 520 is provided with a slide groove 522, and the restrictor passage exit 523 is connected to the slide groove 522. The restrictor member 710 is slidably disposed in the slide groove 522. The restrictor reset member 750 is housed in the slide groove 522, with one end of the restrictor reset member 750 in contact with the restrictor member 710 and the other end in contact with the end of the slide groove 522 away from the restrictor passage exit 523. As a result, when the seat assembly 500 is rotated to a predetermined lateral position, the restrictor member 710 automatically protrudes from the mounting seat 520 into the restrictor groove 720 under the elastic restoring force of the restrictor reset member 750.

[0258] As shown in Figures 41 to 44, the operating assembly 730 is operably mounted on the mounting seat 520 and can be switched between a first position and a second position. When the operating assembly 730 is in the first position, the restricting member 710 is restricted to the unlocked position, thereby allowing the seat assembly 500 to rotate at any angle relative to the base assembly 600. In this case, the misuse prevention function of the misuse prevention structure 700 is not activated. When the operating assembly 730 is in the second position, the restricting member 710 can be switched between the unlocked position and the locked position, and the misuse prevention function of the misuse prevention structure 700 is activated. Specifically, when the operating assembly 730 is in the second position and the regulating member 710 is in the locked position (i.e., the regulating member 710 extends into the regulating groove 720), the regulating member 710 is restricted by the regulating groove 720, and the seat assembly 500 is positioned in a predetermined lateral position (i.e., locked in one direction), thereby restricting the seat components 500 from the predetermined lateral position to the forward-facing use position. At the same time, the seat assembly 500 becomes capable of rotating from the predetermined lateral position to the rearward-facing use position.

[0259] As shown in Figures 43 to 45, the operating assembly 730 includes an operating member 731 and a link mechanism 732, the operating member 731 being connected to the link mechanism 732. In this embodiment, the operating member 731 is detachably connected to the link mechanism 732. As a result, the operating member 731 and the link mechanism 732 have relatively simple structures, making it easy to manufacture them separately and easy to disassemble and assemble them. In some alternative embodiments, the operating member 731 may be fixedly connected to the link mechanism 732 or may be integrally formed with the link mechanism 732.

[0260] The operating member 731 is slidably disposed on the mounting seat 520, and the operating member 731 is provided with an operable operating part 7311 for driving the operating assembly 730 to slide between a first position and a second position by using the operating part 7311. Referring to Figures 41 and 43, in a direction parallel to the rotation axis X3-X3, the operating member 731 is generally located above the link mechanism 732. The mounting seat 520 is provided with a mounting portion 524 and an operating groove 525 disposed through the mounting portion 524. The side of the mounting portion 524 facing the rotation axis X3-X3 of the mounting seat 520 is the inner side 5241, and the inner side 5241 of the mounting portion 524 is an arc. Referring to Figures 42 and 45, the operating member 731 is further provided with an arc portion 7316, and the operating part 7311 is disposed on the arc surface of the arc portion 7316. The arc of the arc portion 7316 has the same arc as the inner surface 5241 of the mounting portion 524. The arc portion 7316 is slidably disposed along the inner surface 5241, and the operating portion 7311 is disposed in the operating groove 525 so as to enable the operating portion 7311 to drive the operating member 731 to slide along the inner surface 5241, thereby driving the link mechanism 732 to slide, and thus the operating assembly 730 is movable between a first position and a second position.

[0261] As shown in FIGS. 43 and 44, a drive surface 7323 is provided on the link mechanism 732. The drive surface 7323 is an inclined surface or an arc surface. Alternatively, the inclined plane includes an inclined plane, a serrated inclined plane, a stepped inclined plane, and the like. The drive surface 7323 is disposed toward the rotation axis X3-X3 of the mounting seat 520. One end of the drive surface 7323 is formed as a first drive end 7321, and the other end of the drive surface 7323 is formed as a second drive end 7322. The distance between the first drive end 7321 and the rotation axis X3-X3 is smaller than the distance between the second drive end 7322 and the rotation axis X3-X3.

[0262] When the operation assembly 730 is in the first position, the drive surface 7323 abuts against the regulating member 710. Specifically, the regulating member 710 abuts against the first drive end 7321. The regulating member 710 extends out of the regulating groove 720, and the regulating member 710 is in the unlocking position. When the operation assembly 730 is in the second position, the drive surface 7323 is separated from or abuts against the regulating member 710. Specifically, the regulating member 710 abuts against the second drive end 7322 or is separated from the drive surface 7323. The regulating member 710 extends into the regulating groove 720, and the regulating member 710 may be switched to the locking position. Thereby, the regulating member 710 can be switched between the unlocking position and the locking position. More specifically, when the regulating member 710 extends into or out of the regulating groove 720, the regulating member 710 remains in contact with the drive surface 7323. During the switching between the first position and the second position of the operating member 730, the regulating member 710 slides along the drive surface 7323. Thereby, the regulating member 710 extends into or out of the regulating groove 720.

[0263] Referring to Figures 39 and 44, in some embodiments the misuse prevention structure 700 may further include a positioning assembly 740. The positioning assembly 740 is configured to restrict the operating assembly 730 to a first or second position. The positioning assembly 740 includes a positioning member 741 and a positioning spring 742. The positioning member 741 is movably disposed on the mounting seat 520 and has a positioning portion 7411 that can extend from the mounting seat 520. The positioning spring 742 is disposed between the positioning member 741 and the mounting seat 520 and provides an elastic restoring force to the positioning portion 741, thereby allowing the positioning portion 7411 of the mounting seat 520 to extend from the mounting seat 520. In some embodiments, the direction of movement of the positioning member 741 is substantially parallel to the rotation axis X3-X3.

[0264] Referring to Figures 43 to 45, the operating member 731 of the operating assembly 730 is provided with a first positioning recess 7312 and a second positioning recess 7313. A positioning projection 7314 is disposed between the first positioning recess 7312 and the second positioning recess 7313. The positioning projection 7314 transitions continuously with the first positioning recess 7312 and the second positioning recess 7313. The positioning part 7411 selectively cooperates with either the first positioning recess 7312 or the second positioning recess 7313 to position the operating assembly 730 to a first or second position. When the operating assembly 730 is switched between a first position and a second position relative to the base assembly 600, the positioning portion 7411 is moved away from the operating member 731 of the operating assembly 730 (more specifically, the positioning projection 7314) (i.e., moved within the mounting seat 520 by the operating member 731). After the positioning projection 7314 has traversed the positioning portion 7411, the positioning portion 7411 moves toward the operating member 731 under the elastic restoring force of the positioning spring 742, cooperating with either the first positioning recess 7312 or the second positioning recess 7313.

[0265] As shown in FIGS. 44 and 45, in this embodiment, the operation member 731 is located above the positioning member 741. The outer surface of the positioning portion 7411 is an arc surface, and the arc surface has the uppermost position 7412. The positioning protrusion 7314 has the lowermost position 7315. When the uppermost position 7412 of the positioning portion 7411 crosses the lowermost position 7315 of the positioning protrusion 7314, the positioning member 741 presses the operation member 731 and moves it by the amount of the arc surface of the positioning portion 7411 under the elastic restoring force of the positioning spring 742. As a result, the positioning portion 7411 is accommodated in one of the first positioning recess 7312 and the second positioning recess 7313 that is closer to the positioning portion 7411. That is, when the lowermost position 7315 of the operation assembly 730 crosses the uppermost position 7412 of the positioning portion 7411, the positioning spring 742 can automatically press and move the operation assembly 730. As a result, the first positioning recess 7312 or the second positioning recess 7313 automatically cooperates with the positioning portion 7411.

[0266] As shown in FIG. 47, in some embodiments, the child seat 100a further includes an indication mechanism 820. The indication mechanism 820 includes an indicating device 8230, a first switch 8210, a second switch 8220, a control device 8250 (see FIG. 49), and a battery 8240 (see FIG. 50). Referring to FIGS. 50 and 51, in this embodiment, the accommodation slot 617 is disposed in the base body 610, and the accommodation slot 617 is recessed with respect to the bottom surface of the base body 610. The base assembly 600 further includes a cover 620, and the cover 620 can be opened and closed at the opening of the accommodation slot 617. When the cover 620 is in the closed state, the side of the cover 620 facing away from the accommodation slot 617 is flush with the bottom surface of the base body 610. An attachment groove 616 is disposed in the accommodation slot 617, and the battery 8240 is detachably disposed in the attachment groove 616. The indicating device 8230, the first switch 8210, the second switch 8220, and the control device 8250 are connected to the battery 8240 via conductive wires.

[0267] As shown in Figures 50 and 51, the cover 620 is pivotably connected to the base body 610 and can be locked in the closed position by using the locking mechanism 630. The cover 620 has opposing first side surfaces 622 and second side surfaces 623. The first side surface 622 is pivotally connected to the base body 610. The locking mechanism 630 is disposed on the base body 610 and is configured to engage with the cover 620.

[0268] The locking mechanism 630 includes an engaging member 631 operably disposed on the base body 610, the engaging member 631 being movable between a locked position and an unlocked position. The engaging member 631 has an engaging end 6311. A locking hole 621 is provided in the cover 620. When the engaging member 631 is in the locked position, the engaging end 6311 extends into the locking hole 621 to enable engagement between the cover 620 and the locking mechanism 630. When the engaging member 631 moves from the locked position to the unlocked position, the engaging end 6311 exits the locking hole 621, and the cover 620 can rotate freely between an open and closed position relative to the base body 610.

[0269] In some embodiments, when the cover 620 is closed, the second side 623 of the cover 620 is housed in a housing slot, and the locking hole 621 is located on the second side 623. The engaging member 631 is slidably disposed on the base body 610 and can be operated. The engaging end 6311 can be inserted into the housing slot 617 and engage with the locking hole 621. The base body 610 is provided with an operating port 6121, which is located on the second housing 612. The engaging member 631 has an engaging operating portion 6313, which faces the operating port 6121 and operates so that the engaging member 631 moves through the operating port 6121. More specifically, the engaging operating portion 6313 extends into the operating port 6121 and can slide within the operating port 6121.

[0270] Referring to Figures 50 and 51, the locking mechanism 630 further includes a reset member 632, which is disposed on the base body 610 and abuts against the engaging member 631. The reset member 632 provides an elastic restoring force to the engaging portion 631 so that the engaging portion 631 can move toward the locked position. That is, the reset member 632 can maintain the engaging member 631 in the locked position such that the engaging end 6311 extends at least partially into the housing slot. In this embodiment, a wedge-shaped surface 6312 is disposed on the engaging end 6311. During the closing of the cover 620 (i.e., in the process of the cover 620 rotating from the open to the closed position), the second side surface 623 presses against the wedge-shaped surface 6312, moving the engaging member 631 from the locked position to the unlocked position. When the cover 620 rotates to completely cover the storage slot (i.e., when the cover 620 rotates to the closed position), the lock hole 621 faces the engaging end 6311, and the engaging member 631 moves from the unlocked position to the engaged position under the action of the reset member 632, thereby engaging the engaging end 6311 with the lock hole 621. This locks the cover 620 in the closed position.

[0271] As shown in Figures 47 and 49, the indicator device 8230 is disposed on the base assembly 600 and is configured to indicate whether the seat assembly 500 is engaged in a predetermined position. A first switch 8210 is disposed on the base assembly 600 and may be electrically connected to the indicator device 8230 by the control device 8250. The first switch 8210 is configured to detect whether the seat assembly 500 is engaged in the forward-facing use position. A second switch 8220 is disposed on the base assembly 600 and may be electrically connected to the indicator device 8230 by the control device 8250. The second switch 8220 is configured to detect whether the seat assembly 500 is engaged in the rearward-facing use position. The control device 8250 generates different instruction signals according to the first switch 8210 and the second switch 8220, and the indicator device 8230 executes instructions according to the different instruction signals. Specifically, when the seat assembly 500 is engaged in the forward-facing use position, the first switch 8210 is closed and the second switch 8220 is open. The control device 8250 receives the closed signal from the first switch 8210 and sends a first instruction signal to the instruction device 8230, to which the instruction device 8230 responds accordingly. When the seat assembly 500 is engaged in the rearward-facing use position, the second switch 8220 is closed and the first switch 8210 is open. The control device 8250 receives the closed signal from the second switch 8220 and sends a second instruction signal to the instruction device 8230, to which the instruction device 8230 responds accordingly. When the seat assembly 500 is located between the forward-facing use position and the rearward-facing use position, and both the first switch 8210 and the second switch 8220 are open, the instruction device 8230 neither instructs nor responds.

[0272] In some embodiments, the indicator device 8230 includes a display screen 8231, which is, for example, a capacitive screen. The content displayed on the display screen 8231 may be different text or different colors. For example, the content displayed on the display screen 8231 may include "under 15 months old" and "15 months old or older". The display screen 8231 is positioned in front of the base assembly 600. Specifically, the front of the base assembly 600 has a connecting seat (also called a leg connecting part) 6122, and the connecting seat 6122 is provided with pivotable legs (also called support legs) 6123. The display screen 8231 is positioned, for example, on the connecting seat 6122 and above the legs 6123. In this way, the display screen 8231 can be easily viewed. Naturally, in other embodiments, the display screen 8231 may be located in other positions on the base assembly 600, for example, on the left or right side of the base assembly 600, and this is not limited herein.

[0278] As shown in Figures 39 and 47, the first drive assembly 8310 is slidably disposed in the base housing space 618. When the first engagement hole 8121 is not engaged by the engagement pin 8110, the first drive assembly 8310 extends at least partially into the first engagement hole 8121. The first drive assembly 8310 includes, for example, a first drive member 8311 and a first pressing member 8312. The first drive member 8311 is movably disposed on the base assembly 600 by a first fixed seat 614. The first pressing member 8312 is connected to the first drive member 8311 and moves together with the first drive member 8311 to press and close the first switch 8210. Both the direction of movement of the first pressing member 8312 and the direction of movement of the first driving member 8311 are parallel to the extending direction of the first engagement hole 8121, and at least a portion of the first pressing member 8312 protrudes laterally from the first driving member 8311.

[0279] Specifically, the first fixed seat 614 is disposed in the housing space 618 and connected to the second housing 612. A first slide groove 6141 is provided in the first fixed seat 614, and a first avoidance groove 6142 is provided on the side wall of the first slide groove 6141. The first switch 8210 is disposed in the first fixed seat 614 and is located outside the first slide groove 6141. The first slide groove 6141 faces the first engagement hole 8121, and the first drive member 8311 is slidably disposed in the first slide groove 6141. The first pressing member 8312 is connected to the first drive member 8311, and a portion of the first pressing member 8312 protrudes from the first slide groove 6141 by the first avoidance groove 6142. The first drive member 8311 has a first cooperating end 83111. When the first engagement hole 8121 is not engaged by the engagement pin 8110, the first cooperating end 83111 extends into the first engagement hole 8121, the first pressing member 8312 is separated from the first switch 8210, and the first switch 8210 is in the open state. In this case, the inner circumferential surfaces of the first cooperating end 83111 and the retaining recess 613 are flush with or inward with respect to the inner circumferential surface of the retaining recess 613. When the first engagement hole 8121 engages with the engagement pin 8110, the first cooperating end 83111 is pressed by the engagement pin 8110 and returned from the first engagement hole 8121 to the first slide groove 6141, and the first pressing member 8312 moves together with the first driving member 8311 to press the first switch 8210, thereby closing the first switch 8210.

[0280] Referring to Figure 39, the first drive member 8311 is pin-shaped. The first drive member 8311 has a first projection 83112 that extends laterally and protrudes from the outer surface of the first drive member 8311, and a first recess 6143 is provided on the side wall of the first slide groove 6141. The first projection 83112 works in cooperation with the first recess 6143 to restrict the first drive member 8311 to the first slide groove 6141 at least partially, so as to prevent the first drive member 8311 from being released from the first slide groove 6141.

[0281] As shown in Figure 47, the first pressing member 8312 is, for example, a spring or a spring plate, but is not limited thereto. In this way, the first pressing member 8312 can partially buffer the force pressing the first switch 8210 so as to prevent excessive external force from being transmitted to the first switch 8210 and causing damage to the first switch 8210. In some embodiments, the first pressing member 8312 is detachably connected to the first drive member 8311. In other embodiments, the first pressing member 8312 is fixedly connected to the first drive member 8311. Alternatively, the first pressing member 8312 is integrally formed with the first drive member 8311.

[0282] Referring to Figure 39, the first reset member 8330 is disposed between the first drive member 8311 and the first fixed seat 614, and the first reset member 8330 biases the first drive member 8311 so that the first drive member 8311 moves toward a position where the first cooperating end 83111 of the first drive member 8311 extends into the first engagement hole 8121. Specifically, the first reset member 8330 is, for example, a pressure spring, and the first drive member 8311 is disposed with a first retaining groove 83113, the opening of which faces the bottom wall of the first slide groove 6141. One end of the first reset member 8330 is disposed in the first retaining groove 83113, and the other end is in contact with the bottom wall of the first slide groove 6141.

[0283] As shown in Figures 39 and 47, in some embodiments, the second drive assembly 8320 may be slidably disposed in the base housing space 618. When the second engagement hole 8122 is not engaged by the engagement pin 8110, the second drive assembly 8320 extends at least partially into the second engagement hole 8122. The second drive assembly 8320 includes, for example, a second drive member 8321 and a second pressing member 8322. The second drive member 8321 is movably disposed on the base assembly 600 by a second fixed seat 615. The second pressing member 8322 is connected to the second drive member 8321 and moves together with the second drive member 8321 to press and close the second switch 8220. Both the direction of movement of the second pressing member 8322 and the direction of movement of the second driving member 8321 are parallel to the extending direction of the second engagement hole 8122, and at least a portion of the second pressing member 8322 protrudes laterally from the second driving member 8321.

[0284] Referring to Figure 40, the second fixed seat 615 is disposed in the housing space 618 and connected to the second housing 612. The second fixed seat 615 is provided with a second slide groove 6151, and a second avoidance groove (not shown) is provided on the side wall of the second slide groove 6151. The structure of the second fixed seat 615 is basically the same as that of the first fixed seat 614. For the structure of the second avoidance groove, refer to the structure of the first avoidance groove 2143. The second switch 8220 is disposed on the second fixed seat 615 and is located outside the second slide groove 6151. The second slide groove 6151 faces the second engagement hole 8122, and the second drive member 8321 is slidably disposed in the second slide groove 6151. The second pressing member 8322 is connected to the second driving member 8321, and a portion of the second pressing member 8322 protrudes from the second slide groove 6151 by the second avoidance groove. The second driving member 8321 has a second cooperating end 83211. When the second engagement hole 8122 is not engaged by the engagement pin 8110, the second cooperating end 83211 extends into the second engagement hole 8122, the second pressing member 8322 is separated from the second switch 8220, and the second switch 8220 is in the open state. In this case, the second cooperating end 83211 is flush with the inner circumferential surface of the retaining recess 613, or faces inward thereto. When the second engagement hole 8122 engages with the engagement pin 8110, the second cooperating end 83211 is pressed by the engagement pin 8110 and returned from the second engagement hole 8122 to the second slide groove 6151, and the second engagement portion 8322 moves together with the second drive member 8321 to press the second switch 8220, thereby closing the second switch 8220.

[0285] Referring to FIG. 40, in some embodiments, the second drive member 8321 is in the shape of a pin. The second drive member 8321 extends laterally and has a second convex portion 83212 protruding from the outer surface of the second drive member 8321. A second concave portion 6153 is disposed on the side wall of the second slide groove 6151. The second convex portion 83212 cooperates with the second concave portion 6153 to at least partially restrict the second drive member 8321 in the second slide groove 6151 so as to prevent the second drive member 8311 from being released from the second slide groove 6151.

[0286] As shown in FIG. 47, the second pressing member 8322 is, for example, a spring or a spring plate, but is not limited thereto. In this way, the second pressing member 8322 can partially buffer the force pressing the second switch 8220 so as to avoid excessive external force being transmitted to the second switch 8220 and causing damage to the second switch 8220. In some embodiments, the second pressing member 8322 is detachably connected to the second drive member 8321. In another embodiment, the second pressing member 8322 is fixedly connected to the second drive member 8321. Alternatively, the second pressing member 8322 is integrally formed with the second drive member 8321.

[0287] Referring to FIG. 39, the second reset member 8340 is disposed between the second drive member 8321 and the second fixed seat 615. The second reset member 8340 is configured to urge the second drive member 8321, whereby the second drive member 8321 moves toward a position where the second cooperating end 83211 of the second drive member 8311 extends into the second engaging hole 8122. Specifically, the second reset member 8340 is, for example, a compression spring. The second drive member 8321 is provided with a second holding groove 83213. The opening of the second holding groove 83213 faces the bottom wall of the second slide groove 6151. One end of the second reset member 8340 is disposed in the second holding groove 83213, and the other end contacts the bottom wall of the second slide groove 6151.

[0288] The operating principle of the child seat 100a, which is equipped with the seat misuse prevention structure 700 according to this application, is as follows.

[0289] For younger children, the child seat 100a must be used in a rear-facing position. In this case, the misuse prevention function of the child seat 100a may be activated, i.e., the operating assembly 730 of the misuse prevention structure 700 may be moved to a second position along the sliding groove 522.

[0290] When the seat assembly 500 is in the forward-facing use position, the engagement pin 8110 engages with the first engagement hole 8121. The engagement pin 8110 pushes the first drive member 8311 out of the first engagement hole 8121, which drives the first press member 8312 to move, thereby pressing and closing the first switch 8210, which in turn causes the display screen 8231 of the indicator device 8230 to display the corresponding content. From the content displayed on the display screen 8231, the caregiver can learn that this mode is not suitable for younger children. Therefore, the seat assembly 500 needs to be adjusted for use in the rear-facing use mode.

[0291] In forward-facing use mode, when the operating assembly 730 moves to the second position, the regulating member 710 of the misuse prevention structure 700 is held in the unlocked position by the regulating wall of the retaining recess 613. To adjust the seat assembly 500 to the rearward-facing use position, the engagement pin 8110 is first released by using the release mechanism, that is, the engagement pin 8110 exits the first engagement hole 8121 by using the release mechanism, and then the seat assembly 500 is rotated around the rotation axis X3-X3.

[0292] During rotation of the seat assembly 500, the engagement pin 8110 is held in the locked position by the regulating wall of the retaining recess 613. When the seat assembly 500 has rotated to a predetermined lateral position, the engagement pin 8110 remains in the released position, and the regulating member 710 extends into the regulating groove 720 while facing the regulating groove 720, under the elastic restoring force of the regulating reset member 750, thereby preventing the seat assembly 500 from rotating in the reverse direction. In this case, a younger group of children may be placed in the seat assembly 500.

[0293] Next, the seat assembly 500 continues to rotate, and the regulating member 710 exits the regulating groove 720 along the guide surface 722 and is regulated to the unlocked position by the regulating wall of the retaining recess 613. When the seat assembly 500 rotates to the rearward use position, the engaging pin 8110 faces the second engaging hole 8122, and under the restoring force of the engaging reset member 8130, the engaging pin 8110 extends into the second engaging hole 8122, thereby locking the seat assembly 500 in the rearward use position. In addition, the engaging pin 8110 presses and moves the second cooperating end 83211 of the second drive member 8321 out of the second engaging hole 8122, and the second drive member 8321 drives the second pressing member 8322 to press and close the second switch 8220, thereby causing the display screen 8231 to display the corresponding content. The caregiver can determine that the child seat 100a is in the correct position based on the information displayed on the display screen 8231.

[0294] When the misuse prevention structure 700 is activated and the seat assembly 500 is in the rearward-facing use position, the seat assembly 500 can be rotated from the rearward-facing use position to a predetermined lateral position by unlocking the engagement pin 8110 with the release mechanism. When the seat assembly 500 is rotated to the predetermined lateral position, the restricting member 710 extends into the restricting groove 720 under the elastic restoring force of the restricting reset member 750, and the restricting member 710 is closed by the locking portion 721, thereby restricting the seat assembly 500 from rotating from the predetermined lateral position to the forward-facing use position. In this case, the seat assembly 500 can only rotate from the predetermined lateral position to the rearward-facing use position.

[0295] In other words, when the misuse prevention structure 700 is activated, the seat assembly 500 can rotate from the forward-facing position to any other position, but cannot rotate from any other position back to the forward-facing position, thereby better preventing the child seat 100a from being misused. In particular, in the rear-facing position, the child seat 100a can rotate within a certain rotational stroke, but cannot rotate to the forward-facing mode, thus preventing caregivers from thinking that the seat assembly 500 is stuck in the rear-facing position and violently rotating the seat assembly 500, thereby improving the user experience of the child seat 100a.

[0296] For older children, the function of the misuse prevention structure 700 may not be activated, meaning the operating assembly 730 may be moved to the first position, and the regulating member 710 may contact the first drive end 7321 of the drive surface 7323 and be regulated in the unlocked position. In this case, the locking pin 8110 can be released by using the locking mechanism so that the seat assembly 500 can rotate within any angular range.

[0297] The misuse prevention structure 700 provided in this embodiment of the present application may also be applied to the first to third embodiments.

[0298] The technical features of the embodiments described above can be combined in any way. For the sake of simplicity, not all possible combinations of the technical features of the embodiments described above are described. However, all of these combinations of technical features should be considered to be within the scope of this application, as long as they do not contradict each other.

[0299] The embodiments described above are only a few embodiments of this application, and their descriptions are relatively specific and detailed. However, this should not be understood as a limitation on the scope of this application. Those skilled in the art should note that several modifications and improvements can be made without departing from the concepts of this application, and such modifications and improvements will fall within the scope of this application. Accordingly, the scope of this application shall be subject to the scope of the claims attached.
