Description

Technical Field

[0001] This invention relates to a child safety seat and a child vehicle. Prior Technology

[0002] Child vehicles (such as child safety seats and strollers) are generally equipped with canopies to prevent direct sunlight and foreign objects from entering the seat. The canopy can be manually unfolded or folded to meet different user needs.

[0003] In addition, to accommodate children of different sizes, child safety seats are usually equipped with an electric angle adjustment mechanism to adjust the seat angle. Generally, the operating device for the angle adjustment mechanism is located on the seat body or base for easy operation. However, for drivers, such as parents, it is difficult to reach the operating device to adjust the seat angle while driving. Furthermore, rotating or adjusting the seat angle can easily cause the wiring to become tangled.

Younger children (e.g., 0 to 9 months) typically need to be seated in rear-facing mode to maximize their safety. However, due to negligence or improper use, caregivers may mistakenly place younger children in forward-facing mode, which undermines the safety function of the child safety seat.

[0120] First Embodiment

[0121] Figures 1 to 3 show a side view and a perspective view of a child vehicle 1000 provided according to a first embodiment of the present invention. The child vehicle 1000 incorporates a canopy connection structure 300 (see Figure 6, hereinafter referred to as the canopy connection structure 300) provided according to an embodiment of the present invention. More specifically, the child vehicle 1000 includes a body 100, a canopy 200, and a canopy connection structure 300, wherein the canopy 200 is detachably mounted to the body 100 via the canopy connection structure 300. The canopy connection structure 300 will be described in conjunction with the description of the child vehicle 1000 below.

[0122] As shown in Figures 1 to 3, the child vehicle 1000 in this embodiment is exemplarily described using a child safety seat as an example. The body 100 includes, for example, a seat body (also called a seat) 11 and a base 12. More specifically, the main body 121 of the base 12 is adapted to be placed on a vehicle seat (not shown) and connected to the ISOFIX connector of the vehicle seat via an ISOFIX connector, such as an ISOFIX plug. The base 12 is provided with a support leg 123, the upper end of which is pivotally connected to a connecting seat 122, which is disposed on the main body 121. The lower end of the support leg 123 is used to abut against the vehicle floor. The seat body 11 is rotatably mounted on the base 12 to provide a forward-facing and rear-facing seating position for the child. Of course, in some alternative embodiments, the body 100 may also have other implementations, for example, the seat body 11 and the base 12 may be fixedly mounted together and not rotatable relative to each other, and the base 12 may not be provided with a support leg 123.

[0123] It should be noted that the types of child vehicles 1000 that can utilize the canopy connection structure 300 provided in this embodiment are not limited to the child safety seats listed in this embodiment. In some alternative embodiments, the child vehicle 1000 may be, for example, an infant carrier, a stroller, a crib, etc. It is understood that the implementation method of the main body 100 will also change accordingly depending on the product type of the child vehicle 1000.

[0124] Referring again to Figures 1 to 3 and Figure 6, in this embodiment, the canopy 200 is detachably mounted on the seat body 11 of the main body 100, more specifically, to mounting positions 110 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 support 21, a positioning support 22, and a canopy 23 (the canopy 23 is exemplarily shown in dashed lines in Figure 1). The active support 21 is pivotally connected to the positioning support 22. The positioning support 22 is used to fix the canopy to the seat body 11. The canopy 23 is connected to both the active support 21 and the positioning support 22.

[0125] When the canopy 200 is installed on the seat body 11 of the main body 100, the positioning bracket 22 is fixed to the seat body 11 and cannot move relative to it. The rotation of the active bracket 21 relative to the positioning bracket 22 can cause the canopy 23 to unfold or fold, so that the canopy 200 has an unfolded state (see Figure 1) and a folded state (see Figure 2). In some alternative embodiments, the canopy 200 may also have at least one intermediate state between the unfolded state and the folded state (e.g., a half-open state). Referring again to Figure 1, the canopy 200 may also include at least one auxiliary bracket 24 connected to the canopy 23. The auxiliary bracket 24 may be pivotally connected to both the positioning bracket 22 and the active bracket 21, or the auxiliary bracket 24 may be fixedly connected only to the canopy 23. When the canopy 200 is unfolded, the auxiliary bracket 24 is used to support the canopy 23 between the active bracket 21 and the positioning bracket 22.

[0126] Referring again to Figures 4 and 5, the structure of the canopy 200 is shown. In this embodiment, both the active support 21 and the positioning support 22 are generally U-shaped. The active support 21 includes two first connecting portions 211 located at both ends of the U-shaped structure of the active support 21. The positioning support 22 includes two second connecting portions 222 located at both ends of the U-shaped structure of the positioning support 22. The two first connecting portions 211 and the two second connecting portions 222 are pivotally connected, allowing the active support 21 to rotate relative to the positioning support 22 about the rotation axis X1-X1. More specifically, taking a pair of pivotally connected first connecting portions 211 and second connecting portions 222 as an example, the first connecting portion 211 includes, for example, a laterally extending cylindrical structure, and the second connecting portion 222 includes, for example, an annular structure, with the cylindrical structure of the first connecting portion 211 fitted within the annular structure of the second connecting portion 222. In some alternative embodiments, the first connecting portion 211 and the second connecting portion 222 may also be pivotally connected together by other suitable structures.

[0127] 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 devices 31, which are installed on both sides of the backrest shell 111 of the seat body 11. Each drive device 31 has a power output component 311, which has the aforementioned rotation axis X1-X1 (see Figure 8). Each power output component 311 is used to connect non-rotatably with the corresponding first connecting part 211 of the active support 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 also include a control device 32. The control device 32 is signal-connected to the drive devices 31 and is used to control the power output component 311 to drive the active support 21 to rotate around the rotation axis X1-X1, so that the canopy 200 automatically unfolds or folds.

[0128] The child vehicle 1000 provided in this embodiment of the invention drives the active support 21 of the canopy 200 to rotate through the control device 32 and the drive device 31, so as to automatically unfold or fold the canopy 200, thereby realizing the automated control of the state adjustment operation of the canopy 200.

[0129] Referring to Figures 3 and 7, in this embodiment, the control device 32 includes, for example, a printed circuit board (not shown) mounted to the connector 122 and a control panel 321. In some alternative embodiments, the control device 32 may be located at any suitable location on the body 100 or at a suitable location outside the body 100.

[0130] Referring to Figure 3, the control panel 321 may include multiple operation buttons 3211. These buttons 3211 may include, but are not limited to, a start button for starting the drive device 31, a stop button for stopping the drive device 31, an unfolded state button corresponding to the unfolded state, a folded state button corresponding to the folded state, and an intermediate state button corresponding to the intermediate state. Users can freely adjust the state of the canopy 200 by operating the start and stop buttons, or by operating the buttons corresponding to different canopy states. In some embodiments, the control panel 321 may include a touch screen (not shown in the figure), allowing users to adjust the state of the canopy 200 by clicking on an indicator area on the touch screen. Of course, in some embodiments, the control panel 321 may adjust the state of the canopy 200 by combining the operation buttons 3211 with the touch screen.

[0131] 7, the control device 32 may also include a wireless communication module 322 , suitable for wireless communication with external equipment 39 which, for example, may be, but is not limited to, various mobile terminals such as mobile phones, smartwatches, smart bracelets, or may be a central control system of a vehicle. In some embodiments, the wireless signal is, for example, a Bluetooth signal, a Wifi signal, and the like. The wireless transmission path or network can be Bluetooth transmission, WiFi, WAPI network and other local area networks. Of course the network can also be 2G, 3G, 4G, 5G and other mobile communication networks. The wireless communication module 322 is used to receive canopy adjustment commands from external equipment 39, according to which the control device 32 controls the action of the driving device 31 such that the canopy 200 adjusts to the desired state.

[0132] By configuring a wireless communication module 322 for the control device 32 , the user is allowed to adjust the state of the canopy 200 at a distance. For example, in some typical usage scenarios, the user riding in the driving position can adjust the state of the canopy 200 of the child vehicle 1000 mounted on the rear seat of the vehicle by operating the external equipment 39. The process of adjusting the state of the canopy 200 does not require the user to leave the driving position, which brings great convenience to the user.

[0133] 8 and 11 , the canopy connection structure 300 of this embodiment may further include a position detection device 33 which is signally connected to the control device 32 and is used to send a position signal to the control device 32 relating to the motion position of the active bracket 21 . When the power output piece 311 drives the active bracket 21 to a predetermined position, the control device 32 control drive device 31 stops driving the active bracket 21, which allows for more precise adjustment of the state of the canopy 200 . The predetermined position of the active scaffold 21 corresponds, for example, to the unfolded state of the canopy 200 , the folded state, or any of the intermediate states between the unfolded and folded states (e.g., the semi-open state).

[0134] Referring to Figures 8 and 11 , an exemplary embodiment of the location detection device 33 is also shown in this embodiment. The position detection device 33 includes, for example, a photoelectric sensor, more specifically, a photoelectric transmitter 331 and a photoelectric receiver 332 . The position detection device 33 is disposed at the periphery of the power output piece 311 and indirectly derives the motion position of the active bracket 21 by detecting the rotation position of the power output piece 311 .

[0135] More specifically, the power output component 311 has, for example, an annular flange 3111 located between the photoelectric transmitter 331 and the photoelectric receiver 332. In some embodiments, the annular flange 3111 has at least two detection ports 3110 arranged circumferentially. As the annular flange 3111 rotates with the power output component 311, when the detection port 3110 passes between the photoelectric transmitter 331 and the photoelectric receiver 332, the photoelectric receiver 332 receives a signal from the photoelectric transmitter 331, and the position detection device 33 then sends a position signal to the control device 32. The control device 32 determines whether the active support 21 has rotated to a predetermined position based on the position signal.

[0136] Of course, the implementation and installation location of the position detection device 33 are not limited to the examples above, as long as it can detect a position signal related to the movement position of the active support 21. For example, in some alternative embodiments, the position detection device 33 can directly detect the movement position of the active support 21. In addition, the type of position detection device 33 is not limited to a photoelectric sensor. In some alternative embodiments, the position detection device 33 can be, for example, a proximity switch, a Hall sensor, or an encoder.

[0137] Referring to Figures 4 and 6, this embodiment illustrates an exemplary connection method between the power output member 311 and the first connecting portion 211 of the active support 21. As previously described, the first connecting portion 211 has a laterally extending cylindrical structure with a laterally extending groove 2110. The power output member 311 has a cylindrical structure adapted to be inserted into the groove 2110, such that the first connecting portion 211 is sleeved with the power output member 311. One of the peripheral wall of the groove 2110 and the outer 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. The protrusion 251 and the recess 252 engage with each other, serving as a rotation limiting mechanism 25 to restrict the relative rotation between the first connecting portion 211 and the power output member 311.

[0138] Of course, in some alternative embodiments, the connection method between the power output member 311 and the first connecting portion 211 is not limited to the above-described sleeve connection; they can also be connected in a non-rotatable manner using other suitable structures. Furthermore, in embodiments where the power output member 311 and the first connecting portion 211 are sleeved together, the rotation limiting mechanism 25 used to restrict the relative rotation between the power output member 311 and the first connecting portion 211 is not limited to the protrusion 251 and recess 252 described above. For example, in some alternative embodiments, the relative rotation between the power output member 311 and the first connecting portion 211 is restricted by tangential surfaces that contact each other.

[0139] Referring again to Figure 6, in this embodiment, a hole is provided at the mounting position 110 of the backrest housing 111, and the power output component 311 is located inside the backrest housing 111 and corresponds to the hole at the mounting position 110. When the canopy 200 is installed onto the seat body 11 of the main body 100, the first connecting 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 engages with the power output component 311. In some alternative embodiments, the power output component 311 can extend from the hole at the mounting position 110, and the first connecting portion 211 is engaged with the first connecting portion 211 on the outside of the backrest housing 111.

[0140] Referring to Figure 6, in this embodiment, the main body 100 (more specifically, backing the housing 111) is provided with a locking hole 112, which is offset from the installation position 110. Referring to Figure 5, the positioning bracket 22 is provided with a locking post 221, which is, for example, located near the second connecting part 222. When the canopy 200 is installed on the main body 100, the locking post 221 is inserted into the locking hole 112, thereby locking the relative position of 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 are laterally opened, and the active bracket 21 and the positioning bracket 22 undergo elastic deformation. The two first connecting parts 211 move in opposite directions along the rotation axis X1-X1 to disengage from the power output component 311, and the two second connecting parts 222 move in opposite directions along the rotation axis X1-X1 to remove the engaging pin 221 from the engaging hole 112, thereby moving the canopy 200 to separate it from the body 100. Of course, in other embodiments, the positioning bracket 22 can also be connected to the body 100 in a non-movably relative manner by other suitable positioning mechanisms. For example, in some alternative embodiments, the outer contour of the back of the housing 111 can be formed with a positioning groove for engaging with the positioning bracket 22.

[0141] Figures 8 to 13 show perspective views, exploded views, and sectional views of some components of the canopy connection structure 300 of this embodiment. The canopy connection structure 300 may also include a mounting base 35, which is fixed to the interior of the back shell 111 of the main body 100, for example, by fasteners (not shown) passing through through holes 350. The drive device 31 may also include a power source 313 and a transmission mechanism 312 (see Figure 12), both of which are mounted on the mounting base 35. The power source 313 is used to output power, and the transmission mechanism 312 is used to transmit the power output by the power source 313 to the power output component 311. The mounting base 35 may also be provided with a retainer 353, on which the position detection device 33 is mounted, for example.

[0142] More specifically, referring to Figure 9, the power source 313 is, for example, an electric motor (or electric motor), mounted on the mounting base 35 via fastener 3132. The power source 313 is signal-connected to the control device 32, and receives commands from the control device 32 to drive the power output component 311 to rotate or stop driving the power output component 311 to rotate. The transmission mechanism 312 is, for example, a gear transmission mechanism, including a drive gear 3123 and an output gear 3122. The drive gear 3123 is drivenly connected to the output shaft 3131 of the power source 313. The drive gear 3123 is directly and non-rotatably connected to the output shaft 3131, for example, or non-rotatably connected via an intermediate piece 3133 installed between them. The drive gear 3123 and the output gear 3122 can be directly meshed or indirectly meshed.

[0143] The output wheel 3122 and the power output component 311 are coaxially connected by a fastener 36. The fastener 36 can be, for example, a rivet or a bolt. The output wheel 3122 has a first end face tooth 3121, and the power output component 311 has a second end face tooth 3112. The first end face tooth 3121 and the second end face tooth 3112 mesh with each other. The power output from the power source 313 is transmitted to the output wheel 3122 via the drive wheel 3123, and then to the power output component 311 via the meshing first end face tooth 3121 and the second end face tooth 3112. The power output component 311 drives the drive bracket 21 to rotate, thereby adjusting the state of the canopy 200.

[0144] Figures 10 to 13 illustrate exemplary assembly structures of the power source 313, transmission mechanism 312, and power output component 311. The mounting base 35, for example, is provided with a first mounting hole 351, at which the drive wheel 3123 is drivenly connected to the output shaft 3131 of the power source 313. The mounting base 35 is also provided with a second mounting hole 352, at which the output wheel 3122 and the power output component 311 are coaxially connected by fasteners 36 installed in the second mounting hole 352.

[0145] More specifically, the second mounting hole 352 is stepped, and the output wheel 3122 has a column 31221 that engages with the second mounting hole 352. The output wheel 3122 has a central hole 31220, and the power output component 311 has a column 3113 that engages with the central hole 31220. The power output component 311 has a first stepped hole 310. The fastener 36 is fitted into the second mounting hole 352, the central hole 31220, and the first stepped hole 310, and serves as the rotation axis of the output wheel 3122 and the power output component 311. Accordingly, the axis of the fastener 36 forms the rotation axis X1-X1 of the power output component 311. The first end 361 of the fastener 36, away from the output wheel 3122, is located inside the first stepped hole 310, which is beneficial for the compactness of the overall structure. Of course, in some alternative embodiments, the first stepped hole 310 can be replaced by a straight hole, which is also within the scope of protection of this invention. Additionally, the first end 361 of the fastener 36 may protrude outward relative to the power output member 311.

[0146] Referring to Figures 12 and 13, in this embodiment, the power output component 311 is axially movable and sleeved on the fastener 36. The canopy connection structure 300 also includes an elastic element 34, which is used to apply an elastic force to the power output component 311 to press the power output component 311 against the output wheel 3122, so that the first end face tooth 3121 and the second end face tooth 3112 remain engaged.

[0147] Referring to Figures 10 and 11, the first end face tooth 3121 has a chamfered portion 31212, and the second end face tooth 3112 has a chamfered portion 31122. When the power output component 311 is subjected to a large circumferential force from the outside, for example, when a user applies a circumferential force to the active bracket 21 to manually adjust the state of the canopy 200, the power output component 311, under the action of the chamfered portions 31212 and 31122, can rotate relative to the output wheel 3122 around the fastener 36, and move away from the output wheel 3122 along the fastener 36, so that the first end face tooth 3121 and the second end face tooth 3112 disengage (i.e., the state shown in Figure 13), allowing the user to manually adjust the state of the canopy 200. That is, the process of the user manually adjusting the canopy 200 does not require rotating the output wheel 3122, thus avoiding damage to the power source 313. In some alternative embodiments, the above-mentioned technical effect can be achieved when only one of the first end face teeth 3121 and the second end face teeth 3112 is provided with a beveled portion. 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 arcuate profile to allow the user to manually adjust the state of the canopy 200.

[0148] It should be noted that by reasonably setting the shape of the first end face tooth 3121 and the second end face tooth 3112 as well as the meshing depth of the end face teeth, it can be ensured that when the power source 313 drives the output wheel 3122, the power output component 311 and the output wheel 3122 rotate synchronously without slipping.

[0149] Referring again to Figures 12 and 13, to facilitate the installation of the elastic element 34, a limiting element 37 is provided at the first end 361 of the fastener 36, and the elastic element 34 is sandwiched between the limiting element 37 and the power output element 311. In this embodiment, the limiting element 37 and the elastic element 34 are located inside the first stepped hole 310, and the limiting element 37 slides with the first stepped hole 310. The elastic element 34 can be a spring sleeved on the fastener 36. More specifically, the first stepped hole 310 includes a first step portion 3101 and a second step portion 3102, with the first step portion 3101 being closer to the limiting element 37 than the second step portion 3102. The limiting element 37 is used to limit the axial movement stroke of the first step portion 3101. The elastic element 34 is sandwiched between the limiting element 37 and the second step portion 3102. In some alternative embodiments, the second step portion 3102 may not be provided, and the elastic element 34 may be sandwiched between the limiting element 37 and the first step portion 3101.

[0150] Referring to Figures 8, 12, and 13, in this embodiment, the limiting member 37 and the power output member 311 cannot rotate relative to each other. More specifically, the outer peripheral contour of the limiting member 37 engages with the inner peripheral contour of the first stepped hole 310 of the power output member 311. The limiting member 37 has a second stepped hole 370, through which it is sleeved on the fastener 36, and the first end 361 of the fastener 36 is more specifically located inside the second stepped hole 370. In some embodiments, a washer 38, which is sleeved on the fastener 36, may also be provided inside the second stepped hole 370. This washer 38 may be made of a wear-resistant material with a low coefficient of friction. In some alternative embodiments, the limiting member 37 is, for example, an integral structure with the fastener 36. In some alternative embodiments, the limiting member 37 has, for example, a cylindrical structure and is pivotally connected to the first stepped hole 310 of the power output member 311.

[0151] The following is a brief description of the working process of the child vehicle 1000, which uses the canopy connection structure 300 provided in the first embodiment of the present invention, when adjusting the canopy state.

[0152] The child vehicle 1000 is, for example, a child safety seat installed in the rear seat of a vehicle. When a user (driver or other passenger) wishes to automatically adjust the canopy of the child safety seat to a desired state, the user can issue a canopy adjustment command to the control device 32 by operating an external device 39 (e.g., a mobile terminal or the vehicle's central control system) or a control panel 321. Upon receiving the canopy adjustment command, the control device 32 transmits a signal to the drive device 31, and the power source 313 of the drive device 31 transmits power to the power output component 311 through the transmission mechanism 312. The power output component 311 drives the active support 21 to rotate until the position detection device 33 detects that the power output component 311 has rotated to a position (corresponding to the desired state of the canopy 200), at which point the control device 32 controls the power source 313 to stop outputting power. The canopy 200 is then held in the desired state.

[0153] The canopy connection structure 300 provided in the first embodiment of the present invention can be modified as follows:

[0154] 1. In some alternative embodiments, the main body 100 is provided with a slide rail that slides with the active support 21 of the canopy 200, and the control device 32 controls the power output component 311 to drive the active support 21 to move along the slide rail so that the canopy 200 can be unfolded or folded.

[0155] 2. In some alternative embodiments, the canopy 200 is non-detachably connected to the body 100, for example. For example, fastener 36 non-detachably mounts the first connection 211 of the active support 21 to the body 100.

[0156] Third, in some alternative embodiments, the transmission mechanism 312 having the output wheel 3122 is not limited to a gear transmission mechanism. For example, the transmission mechanism 312 may include a rack and pinion transmission mechanism or a worm gear transmission mechanism.

[0157] IV. In some alternative embodiments, the canopy connection structure 300 may include a drive device 31, a first connection portion 211 of the active support 21 is connected to the power output component 311 of the drive device 31, and another first connection portion 211 is pivotally connected to the body 100 via a pivot.

[0158] V. In some alternative embodiments, the drive device 31 may not have a drive wheel 3123. The output shaft 3131 of the power source 313 is coaxially connected to the output wheel 3122 and cannot rotate relative to it. The power of the power source 313 can be transmitted to the output wheel 3122 over a short distance. In some embodiments, the output wheel 3122 is directly connected to the output wheel 3122 by a spline connection or a slit connection, or it can be connected by means of an intermediate member located between the two.

[0159] Second Embodiment

[0160] Figures 14 and 15 show a side view and a perspective view of a child vehicle 1000 according to a second embodiment of the present invention, the child vehicle 1000 employing a canopy connection structure 300 according to an embodiment of the present invention. Unless otherwise specified, the structure of the child vehicle 1000 and the canopy connection structure 300 in this second embodiment can be referred to the description in the first embodiment described above.

[0161] Referring to Figures 14 and 15, unlike the first embodiment described above, the canopy 200 of this second embodiment may not have a positioning bracket 22, and features related to the positioning bracket 22 can be omitted accordingly. More specifically, the canopy 200 of this second embodiment includes an active bracket 21 and a canopy 23, with the canopy 23 connected to the main body 100 and the active bracket 21. The canopy 23 is, for example, connected to the top of the backrest shell 111 of the seat body 11. When the control device 32 controls the power output component 311 to drive the active bracket 21 to move, the canopy 200 can automatically unfold or fold.

[0162] In this second embodiment, the active support 21 and the main body 100 can be detachably or non-detachably connected. Correspondingly, the tarpaulin 23 and the main body 100 can be detachably or non-detachably connected.

[0163] The canopy connection structure 300 provided in the first and second embodiments of the present invention can also be applied to the third and fourth embodiments described below.

[0164] Third Embodiment

[0165] Referring to Figures 16 to 18, the third embodiment of this application provides an angle-adjustable child safety seat 100a. Unless otherwise specified, the structure of the child safety seat 100a provided in this third embodiment can refer to the child safety seats described in the above embodiments, and the child safety seat can also utilize the aforementioned canopy connection structure 300.

[0166] Referring to Figures 16 to 18, the child safety 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 (also known as the tilt angle) of the seat body 11 relative to the base 12 changes as the seat body 11 slides relative to the base 12. For example, referring to Figures 17 and 18, the sliding of the seat body 11 relative to the base 12 causes the tilt angle of the seat body 11 to switch between an upright position shown in Figure 17 and a reclining position shown in Figure 18. The seat body 11 may also have multiple tilt positions between the upright and reclining positions to meet the personalized sitting and sleeping posture requirements of the infant. In some embodiments, the seat body 11 may be an infant carrier.

[0167] Referring to Figures 19 to 21, in one embodiment, the child safety seat 100a further includes: a sliding rod 131, a sliding groove 113, a drive rod 114, and a drive mechanism 41.

[0168] A sliding rod 131 is disposed on the base 12. In some embodiments, a rotating member 13 is disposed on the base 12, and the sliding rod 131 is more specifically disposed on the rotating member 13. A sliding groove 113 is formed, for example, on the seat body 11. The sliding rod 131 is inserted into the sliding groove 113, and the sliding rod 131 is able to slide in the sliding groove 113 to guide the seat body 11 to slide relative to the base 12, so as to adjust the tilt angle of the seat body 11.

[0169] In this embodiment, the rotating member 13 can pivot relative to the base 12 about the rotation axis X2-X2, while the seat body 11 and the rotating member 13 cannot pivot relative to each other about the rotation axis X2-X2. Thus, when the rotating member 13 pivots relative to the base 12, the seat body 11 is allowed to switch between a forward-facing use position and a rearward-facing use position.

[0170] A drive rod 114 is mounted on the seat body 11. A drive mechanism 41 is mounted on the base 12. In this embodiment, the drive mechanism 41 is more specifically mounted on the rotating member 13. The drive mechanism 41 is coupled to the drive rod 114 and can push the drive rod 114 to reciprocate, thereby driving the seat body 11 to slide relative to the base 12, thus realizing automatic adjustment of the tilt angle of the seat body 11.

[0171] Optionally, the sliding groove 113 is formed as an arcuate groove, and the drive mechanism 41 is pivotally connected to the base 12. In this embodiment, the drive mechanism 41 is more specifically pivotally connected to the rotating member 13. When the seat body 11 slides, the drive mechanism 41 can swing relative to its pivot point with the base 12 (or the rotating member 13). The extension direction of the pivot axis of the drive mechanism 41 relative to the base 12 is orthogonal to the direction of the reciprocating motion of the drive rod 114.

[0172] Optionally, the seat body 11 and the sliding groove 113 are a single piece, and the inner peripheral wall of the sliding groove 113 is made of plastic. Referring to Figure 21, optionally, the seat body 11 is provided with a reinforcing rib 1122 extending in the vertical direction, and the sliding groove 113 is formed on the reinforcing rib 1122.

[0173] Referring to Figure 21, in one embodiment, a reinforcing member 1133 is further provided on the outer side of the sliding groove 113. The reinforcing member 1133 has a sheet-like structure, more specifically a thin sheet. The reinforcing member 1133 may be made of metal and is fixed together with the seat body 11. The reinforcing member 1133 has a through groove 11331 adapted to the shape of the sliding groove 113, so that the sliding rod 131 can slide in the through groove 11331. The provision of the reinforcing member 1133 strengthens the structural strength of the sliding fit structure formed by the sliding rod 131 and the sliding groove 113, and avoids the sliding rod 131 from wearing down the sliding groove 113 during sliding, thereby improving the service life of the sliding fit structure. Optionally, the thickness of the reinforcing member 1133 is less than the depth of the sliding groove 113.

[0174] Both ends of the drive rod 114 are fixedly connected to two reinforcing members 1133 arranged on the left and right. The fixed connection of the drive rod 114 to the reinforcing members 1133 enhances the connection strength between the drive rod 114 and the seat body 11, and prevents the fixed connection between the drive rod 114 and the base 12 from failing due to long-term reciprocating motion, thus preventing loosening.

[0175] Referring also to Figures 28 and 34, in some embodiments, the child safety seat 100a further includes a control mechanism 42, which is disposed on the seat body 11 and / or the base 12, and is electrically connected to a drive mechanism 41. The control mechanism 42 is used to send control signals to the drive mechanism 41, and the drive mechanism 41 drives the seat body 11 to slide relative to the base 12 according to the received control signals.

[0176] In one embodiment, a rotating connector 132 is provided at the center of the rotating member 13, and an electric slip ring 133 passes through the middle of the rotating connector 132. The operation panel 431 and the control mechanism 42 (more specifically, the seat circuit board 421 described below) are electrically connected via the electric slip ring 133. That is, the electrical connection between the base 12 and the seat body 11 is achieved through the electric slip ring 133.

[0177] Optionally, the control mechanism 42 may include a base circuit board 124 disposed on the base 12. Optionally, the base circuit board 124 is disposed below the operation panel 431 and electrically connected to the operation panel 431.

[0178] Referring to Figure 9, as previously described, the base 12 also includes a rotating member 13, which is rotatably mounted on the base 12 and connected to the seat body 11. The rotating member 13 is capable of rotating 360 degrees relative to the base 12 along the rotation axis X2-X2, thereby causing the seat body 11 to rotate relative to the base 12, thus adjusting the orientation of the seat body 11 towards the front or rear of the vehicle's direction of travel. As previously described, the drive mechanism 41 is pivotally connected to the rotating member 13.

[0179] Referring also 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 fixedly mounted on the bracket 414. The screw 412 is rotatably mounted in 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 sleeved on the screw 412 and threadedly engaged with it; the drive block 413 is also connected to the seat body 11. More 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 transmission mechanism. One end of the bracket 414 is pivotally connected to the base 12, for example, via a pivot pin 415. In embodiments with a rotating member 13, 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. Optionally, the free end of the bracket 414 is fitted inside the backrest of the seat body 11.

[0180] Motor 411 drives screw 412 to rotate, thereby driving drive block 413 to move along the length of screw 412. For example, when screw 412 rotates clockwise, drive block 413 moves upward along the length of screw 412. When screw 412 rotates counterclockwise, drive block 413 moves downward along the length of screw 412. The movement of drive block 413 along the length of screw 412 can drive seat body 11 to slide relative to base 12, thereby changing the tilt angle of seat body 11.

[0181] During the pivoting process of the bracket 414 relative to the base 12, the angle between the length direction of the screw 412 and the vertical direction is always an acute angle.

[0182] Referring also to Figures 22 and 23, in one embodiment, as previously described, a drive rod 114 is provided on the seat body 11. A drive block 413 is provided with a connecting hole 4131. The drive rod 114 passes through the connecting hole 4131, thereby connecting the drive block 413 to the seat body 11. When the drive block 413 moves along the length of the screw 412, the drive block 413 drives the seat body 11 to slide relative to the base 12 because the drive rod 114 engages in the connecting hole 4131.

[0183] Referring to Figures 24 and 25, in one embodiment, the motor 411 includes an output shaft 4111, with a first tooth 41111 on its outer surface. A transmission gear 4121 is fixedly mounted on the screw 412, and the transmission gear 4121 has a second tooth 41211. Through the meshing of the first tooth 41111 and the second tooth 41211, the motor 411 drives the screw 412 to rotate. The output shaft 4111 and the transmission gear 4121 are, for example, part of a worm gear transmission mechanism. Specifically, when the output shaft 4111 of the motor 411 rotates clockwise or counterclockwise, the rotational motion of the output shaft 4111 is transmitted to the screw 412 through the meshing of the first tooth 41111 and the second tooth 41211, causing the screw 412 to rotate, thereby realizing that the motor 411 drives the screw 412 to rotate.

[0184] Referring again 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 sleeved on the screw 412, and the internal thread of the through hole 4132 engages with the external thread 4122 of the screw 412. Through the engagement of the internal thread and the external thread 4122, and by restricting the rotation of the drive block 413 about the axis of the screw 412 through a suitable structure, the rotation of the screw 412 can drive the drive block 413 to move in the length direction of the screw 412. Specifically, the motor 411 drives the screw 412 to rotate, and the rotation of the screw 412 drives the drive block 413 to move in the length direction of the screw 412. The movement of the drive block 413 can be transmitted to the drive rod 114, which drives the seat body 11 to slide relative to the base 12.

[0185] Referring to Figures 22 to 24, in one embodiment, the bracket 414 is provided with a receiving groove 4142. Two opposite ends of the receiving groove 4142 are respectively provided with a first mounting groove 41421 and a second mounting groove 41422. The screw 412 is rotatably disposed in the receiving groove 4142. The driving block 413 is fitted into the receiving groove and can move along the length direction of the receiving groove 4142. The cooperation between the driving block 413 and the receiving groove 4142 restricts the rotation of the driving block 413 about the axis of the screw 412.

[0186] Referring to Figure 24, a first support member 4123 and a second support member 4124 are respectively fitted onto the two opposite ends of the screw 412. The first support member 4123 and the second support member 4124 are respectively disposed in the first mounting groove 41421 and the second mounting groove 41422. When the screw 412 rotates, the first support member 4123 and the second support member 4124 rotate in the first mounting groove 41421 and the second mounting groove 41422, respectively. Optionally, the first support member 4123 and the second support member 4124 are made of wear-resistant materials such as steel or copper.

[0187] Referring to Figure 23, in one embodiment, a first cover plate 4143 is provided on a portion of the first mounting groove 41421 of the bracket 414, covering the first mounting groove 41421 to confine the first support member 4123 within the first mounting groove 41421; a second cover plate 4144 is provided on a portion of the second mounting groove 41422 of the bracket 414, covering the second mounting groove 41422 to confine the second support member 4124 within the second mounting groove 41422. Optionally, the first cover plate 4143 and the second cover plate 4144 are fixed to the bracket 414 by bolts, screws, etc.

[0188] Referring to Figure 22, in one embodiment, a plurality of position sensors 4141 are provided on the bracket 414. Optionally, the plurality of position sensors 4141 are arranged at intervals on the bracket 414 along the length direction of the screw 412. The drive block 413 is provided with a detection plate 4133, for example, the detection plate 4133 is a thin sheet extending from the drive block 413 and protruding into the bracket 414. When the drive block 413 moves along the length direction of the screw 412 to such that the detection plate 4133 enters the sensing area of ​​the position sensor 4141, the position sensor 4141 sends an identification signal to the control mechanism 42, which is related to the tilt angle of the seat body 11.

[0189] Referring to Figures 19 and 22, optionally, a first position sensor 4141a and a third position sensor 4141c are respectively provided at the upper and lower limit positions of the support 414 corresponding to the movement stroke of the drive block 413. The terms "upper limit position" and "lower limit position" in this document refer to, with reference to the directions in Figures 19 and 22 to 25, the "upper limit position" corresponding to the upper limit position of the drive block 413's upward movement and the "lower limit position" corresponding to the lower limit position of the drive block 413's downward movement. Optionally, a second position sensor 4141b is provided at the middle position of the support 414 corresponding to the movement stroke of the drive block 413. The term "middle position" in this document refers to, with reference to the direction in Figure 8, the approximate midpoint between the upper limit position and the lower limit position of the drive block 413's downward movement.

[0190] Referring to Figures 19 and 22, in one embodiment, the drive block 413 may also be provided with a limiting member 4134, which protrudes from the drive block 413 in the direction of movement of the drive block 413. When the drive block 413 reaches the upper or lower limit position of its travel, the limiting member 4134 abuts against the bracket 414 or a suitable structure of the rotating member 13, to prevent the drive block 413 from continuing to move away from the upper or lower limit position. For example, in the event of a failure of the control mechanism 42, if the drive block 413 continues to move away from the upper and lower limit positions after reaching the lower limit position of its travel, the limiting member 4134 will abut against the corresponding part of the bracket 414 to prevent the drive block 413 from continuing to move and to avoid damage to the drive mechanism 41.

[0191] In this embodiment, the limiting member 4134 protrudes from the drive block 413 toward the motor 411 to prevent the drive block 413 from colliding with and damaging the motor when it moves toward the motor 411. Optionally, the limiting member 4134 is a protrusion on the drive block 413 extending toward the upper or lower limit position. Optionally, the limiting member 4134 is integrally formed with the drive block 413. Optionally, the limiting member 4134 is fixedly connected to the drive block 413. Optionally, the limiting member 4134 is located on the side of the drive block 413 facing the lower limit position.

[0192] Referring to Figures 19 and 21, in one embodiment, a support plate 135 is fixedly connected to the rotating member 13. A sliding rod 131 passes through the two left-right opposite support plates 135. The seat body 11 is provided with a sliding groove 113. The sliding rod 131 is inserted into the sliding groove 113 and slides in the sliding groove 113 to guide the sliding of the seat body 11 relative to the base 12 and change the tilt angle of the seat body 11.

[0193] Specifically, in this embodiment, the rotating member 13 is provided with two parallel sliding rods, namely a first sliding rod 1311 and a second sliding rod 1312. The seat body 11 is provided with a first sliding groove group 1131 and a second sliding groove group 1132. The first sliding groove group 1131 includes two sliding grooves 113 arranged opposite each other. The second sliding groove group 1132 includes two other sliding grooves 113 arranged opposite each other. The first sliding rod 1311 is inserted into the first sliding groove group 1131 and slides within it. The second sliding rod 1312 is inserted into the second sliding groove group 1132 and slides within it.

[0194] Optionally, a reinforcing member 1133 is provided to cover the sliding groove 113 to reduce wear between the sliding rod 131 and the sliding groove 113. Specifically, the reinforcing member 1133 is a sheet structure made of metal, and a through groove 11331 is provided on the reinforcing member, which overlaps with the sliding groove 113. In this embodiment, the sliding groove 113 is integrally formed on the seat body 11, thereby the sliding groove 113 is formed from the plastic material of the seat body 11. The sliding groove 113 can be formed directly in the mold cavity as a protrusion structure during the molding process of the seat body 11, such as on a reinforcing rib, or it can be obtained by drilling after the seat body 11 is molded. The two ends of the sliding rod 131 are inserted into the sliding groove 113, which can increase the contact area between the sliding rod 131 and the inner wall of the sliding groove 113, so as to avoid the sliding groove 113 made of plastic material from being damaged due to excessive local stress. When the sliding rod 131 slides within the sliding groove 113, the plastic material of the sliding groove 113 helps reduce the noise generated when the sliding rod 131 slides. Furthermore, since the sliding groove 113 is formed from the plastic material of the seat body 11, the manufacturing cost is low.

[0195] As described above, in some embodiments, a metal reinforcing member 1133 is provided at each sliding groove 113, and the reinforcing member is provided with a through groove 11331, the through groove 11331 being adapted to the shape of the sliding groove 113. Each sliding rod 131 slides in engagement with the corresponding sliding groove 113 and through groove 11331, which reduces wear between the sliding rod 131 and the sliding groove 113. Furthermore, the reinforcing member ensures the structural strength of the sliding groove 113.

[0196] Compared to a design where the sliding groove 113 is mounted on the rotating member 13 and the sliding rod 131 is mounted on the seat body 11, in this embodiment, the sliding groove 113 can be integrally formed with the seat body 11, and the sliding groove can achieve sufficient structural strength without being formed on a metal part. The structural strength of the sliding groove is further enhanced by the reinforcing member 1133. The solution of this embodiment can also reduce the weight and cost of the child safety seat 100a.

[0197] Optionally, the sliding groove 113 is arc-shaped, allowing the seat body 11 to slide relative to the base 12 along an arc-shaped sliding trajectory. As described above, one end of the bracket 414 is pivotally connected to the base 12 via a pivot pin 415, so that the direction of movement of the drive block 413 is consistent with the shape direction of the sliding groove 113. While pushing the drive rod 114 to move, the drive block 413 swings together with the bracket 414 around the pivot point between the bracket 414 and the rotating member 13 to accommodate the sliding of the seat body 11 relative to the rotating member 13.

[0198] The working principle of a child safety seat 100a according to an embodiment of this application is described in detail below with reference to Figures 17 to 19 and Figures 21 to 25.

[0199] As shown in Figure 17, the seat body 11 is, for example, in an upright position. At this time, the drive block 413 is, for example, in the upper limit position. At this time, the user (e.g., the driver or passenger driving the vehicle) sends a command to the control mechanism 42 to adjust the seat (tilt) angle by pressing the control button on the remote control device 432 (described below) or 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 the 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 through the cooperation of the drive rod 114 and the connecting hole 4131, so that the seat body 11 has a tendency to move. Through the cooperation of the sliding rod 131 and the arc-shaped sliding groove 113, the tendency of the seat body 11 to move is realized as the seat body 11 sliding relative to the base 12. 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 to accommodate the shape of the sliding groove 113. Thus, the angle of the seat body 11 gradually changes from the upright state shown in FIG. 2 to the reclining state shown in FIG. 3, and vice versa. Therefore, the driver or passenger driving the vehicle can easily adjust the angle of the child safety seat 100a provided in the embodiments of this application.

[0200] Referring also to Figures 20 and 28, in one embodiment, as previously described, the rotating member 13 is provided with a circular rotating connector 132. The rotating connector 132 is, for example, fixedly connected to the base 12 and pivotally connected to the rotating member 13. In some embodiments, a gap exists between the rotating connector 132 and the rotating member 13, and the upper shell of the base 12 is rotatably held within the gap. The rotating member 13 is rotatably mounted on the base 12 via the rotating connector 132, the edge of which has an annular flange that slides within an annular groove in the upper shell of the base. As described above, the rotating connector 132 is also provided with an electrical slip ring 133, which maintains the electrical connection between components mounted on the seat body 11 and components mounted on the base 12 when the seat body 11 rotates.

[0201] Referring to Figures 16 and 28, in one embodiment, the child safety seat 100a further includes an operating mechanism 43. The operating mechanism 43 includes an operating panel 431 disposed on the base 12 and electrically connected to a control mechanism 42. The operating panel 431 includes control buttons 433 for adjusting the (tilt) angle of the seat body 11. The user can operate the tilt 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 to change the angle of the seat body 11.

[0202] Optionally, in one embodiment, the control button 433 may include a power switch 4331 and a tilt angle button for controlling the tilt angle of the seat body 11. After pressing the power switch 4331, the tilt angle of the seat body 11 can be adjusted by pressing the tilt decrease button or tilt increase button on the control button 433. In some embodiments, the control button may also be replaced by a touch screen, a remote control, or a mobile application, etc.

[0203] Referring to Figures 21 and 26, in one embodiment, the control mechanism 42 includes: a seat circuit board 421, a mounting box 422, and a mounting cover 423. The mounting box 422 is disposed on the seat body 11, the seat circuit board 421 is disposed in the mounting box 422, and the mounting cover 423 covers the mounting box 422 to close the mounting box 422.

[0204] Referring also to Figures 28 and 34, in one embodiment, the seat circuit board 421 is electrically connected to the slip ring 133, the drive mechanism 41, and the position sensor 4141, while the operation panel 431 and the base circuit board 124 are electrically connected to the slip ring 133, thereby achieving electrical connection between the control mechanism 42 and other components. Optionally, electrical connection can be achieved via wire connection. In this application, the term "electrical connection" includes connections for transmitting electrical energy and connections for transmitting electrical signals.

[0205] Referring to Figures 30 to 33, in one embodiment, the child safety seat 100a may further include a remote control device 432. The remote control device 432 can establish a wireless communication connection with the control mechanism 42 via radio frequency, Bluetooth, or other means, and transmit control signals to the control mechanism 42, so that the control mechanism 42 controls the 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.

[0206] Optionally, the remote control device 432 may be a remote controller, which is wirelessly and communicatively connected to the control mechanism 42. The remote controller may include, for example, an upper cover 4321 and a lower cover 4322 that are detachably interlocked, and a battery 4323. Optionally, the upper cover 4321 and the lower cover 4322 are interlocked by a first latching protrusion 4327 on the upper cover 4321 and a second latching protrusion 4326 on the lower cover 4322. Optionally, the upper cover 4321 and the lower cover 4322 may also be interlocked by other suitable methods, such as bolted connections, magnetic connections, etc., and this application does not limit this.

[0207] Referring to Figure 31, optionally, the remote control also includes a disassembly port 4325 to facilitate the separation of the interlocking upper cover 4321 and lower cover 4322. Referring to Figures 32 and 33, a receiving space 4324 is defined between the upper cover 4321 and lower cover 4322, in which a replaceable battery 4323 is disposed. Optionally, the remote control includes control buttons for switching between upright and reclining modes.

[0208] Referring also to Figures 28 and 34, one embodiment of this application provides a child safety 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 labeled in the figures, representing the main structure for placement on a vehicle seat) and pivotally connected to the rotating member 13, allowing the rotating member 13 to 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 can also be referred to as the tilt angle of the seat body 11 relative to the rotating member 13.

[0209] Referring to Figure 16, in some embodiments, the base 12 may be provided with a power input port 126, which is connected to the vehicle power supply, for example. The power supply system (e.g., the vehicle power supply) supplies power to the child safety seat 100a through the power input port 126.

[0210] As described above, the base 12 is provided with a base circuit board 124, and the seat body is provided with a seat circuit board 421. A rotating connector 132 is provided with an electric slip ring 133. The base circuit board 124 is electrically connected to the seat circuit board 421 via the electric slip ring 133. Specifically, referring to FIG35, the base circuit board 124 is electrically connected to the electric slip ring 133, for example, via a first wire 124a. The electric slip ring 133 is electrically connected to the seat circuit board 421, for example, via a second wire 133a. The seat circuit board 421 is electrically connected to the drive mechanism 41, for example, via a third wire 421a. The power input port 126 can be electrically connected to the base circuit board 124; that is, the power supply system is electrically connected to the base circuit board 124.

[0211] As previously described, the drive mechanism 41 includes a motor 411 and multiple position sensors 4141. The seat circuit board 421 is used to drive the motor 411 to operate or control the motor 411 to stop operating based on the signals from the position sensors 4141. The base circuit board 124 is used to supply power to the seat circuit board 421 and to send control signals for controlling the adjustment of the seat (tilt) angle. For details regarding the specific structures of the drive mechanism 41, seat circuit board 421, and base circuit board 124, please refer to the drive mechanism 41, control mechanism 42, and operating mechanism 43 in other embodiments of this application.

[0212] By setting up the seat circuit board 421, the base circuit board 124, and the electric slip ring 133, on the one hand, the pivoting and sliding of the seat body 11 will not affect the wires between the electric slip ring 133 and the base circuit board 124, ensuring the stability of the electrical connection between the slip ring 2014 and the base circuit board 124; on the other hand, when the seat body 11 pivots and slides, the wires between the seat circuit board 421 and the electric slip ring 133 are not easily tangled.

[0213] Generally, in child safety seats, electronic components such as motors, sensors, fans, and heating elements are typically located in the seat body, while the power input port 126 and button panel are usually located in the base of the child safety seat. These electronic components and the power input port are connected to a control circuit board composed of a microcontroller and its peripheral circuitry, which is usually located in the base of the child safety seat. The electrical connection wires between electronic components such as motors and sensors and the control circuit board are typically six to eight, while the electrical connection wires between electronic components such as fans and heating devices and the control circuit board are at least six. Therefore, a wiring harness consisting of six to fifteen wires needs to be run between the base 12 and the seat body 11. When the seat body 11 rotates 360 degrees relative to the base or its tilt angle is adjusted, the wiring harness will be pulled, easily causing tangling between the wires or interference between the wires and the movable mechanical structures inside the child safety seat shell.

[0214] In this embodiment, a circuit board is provided at both the seat body 11 and the base 12, namely, a base circuit board 124 and a seat circuit board 421. The base circuit board 124 is used to connect the power input port and control buttons, while the seat circuit board 421 is used to control electronic components such as motors. Only two to three power and control wires are transmitted between the seat circuit board 421 and the base circuit board 124 through an electric slip ring 133, effectively reducing wire tangling and interference. The remote control device 432 can, for example, be wirelessly connected to the base circuit board 124 or the seat circuit board 421 to control the operation of the motor 411.

[0215] Referring again to FIG. 35, in one embodiment, the seat body 11 includes a backrest section 1103 and a seat section 1104, with the backrest section 1103 connected to the seat section 1104. In some embodiments, the intermediate section between the backrest section 1103 and the seat section 1104 is a curved surface approaching 90 degrees. In some embodiments, the backrest section 1103 and the seat section 1104 together form a generally L-shaped structure. A seat circuit board 421 is disposed, for example, at the connection between the backrest section 1103 and the seat section 1104. A cavity is formed between the seat circuit board 421 and the rotating member 13, and a second wire 133a between the slip ring 133 and the seat circuit board 421 hangs within this cavity.

[0216] When the seat body 11 and the rotating component 13 rotate relative to the base 12, the first wire 124a between the slip ring 133 and the base circuit board 124, and the third wire 421a between the seat circuit board 421 and the drive mechanism 30, will not move due to force. The second wire 133a between the slip ring 133 and the seat circuit board 421 is connected to one end of the seat body 11 and rotates under the circumferential force provided by the seat body 11 in the direction of rotation, while the other end connected to the slip ring 133 drives the slip ring 133 to pivot.

[0217] When the seat body 11 slides back and forth relative to the base 12, the first wire 124a will not move due to force. When the seat body 11 slides to the foremost position relative to the base 12, that is, when the seat body 11 is at its largest tilt angle, as shown in Figure 35, the second wire 133a is in a relatively slack state because the distance between the slip ring 133 and the seat circuit board 421 (the middle section between the backrest section 1103 and the seat section 1104) is closest. At the same time, the distance between the seat circuit board 421 and the rotating component is farthest, and the third wire 421a is in a relatively tight state. When the seat body 11 slides to the rearmost position relative to the base 12, that is, when the seat body 11 is at its smallest tilt angle, the distance between the slip ring 133 and the seat circuit board 421 (the middle section between the backrest section 1103 and the seat section 1104) is farthest, and the second wire 133a is in a relatively tight state. At the same time, the distance between the seat circuit board 421 and the rotating component is closest, and the third wire 421a is in a relatively slack state. Therefore, during the rotation or back-and-forth sliding of the seat body 11, interference is unlikely to occur between the second wire 133a and the third wire 421a. The cavity provides a space to accommodate the loose and drooping second wire 133a, preventing the wire from getting tangled or hooked on other components inside the child safety seat due to deformation.

[0218] Referring again to Figure 35, in one embodiment, the slip ring 133 is configured such that, during the sliding of the seat body 11 relative to the base 12, the extension line of the axis of the slip ring 133 always intersects the seat segment 1104 of the seat body 11. This limits the pulling direction and deformation range of the wires between the slip ring 133 and the seat circuit board 421 during the sliding of the seat body, preventing the wires from getting tangled on the seat circuit board 421, the slip ring 133, or other components inside the child safety seat.

[0219] Optionally, the seat circuit board 421 is configured such that, during the sliding of the seat body 11 relative to the base 12, the projection of the seat circuit board 421 onto the base 12 always covers the slip ring 133. This further restricts the pulling direction and deformation amplitude of the wires between the slip ring 133 and the seat circuit board 421 during the sliding of the seat body 11, preventing the wires from becoming entangled in the seat circuit board 421, the slip ring 133, or other components inside the child safety seat.

[0220] Referring again to FIG. 35, in this embodiment, as previously described, the drive mechanism 41 is disposed on the rotating member 13 and extends toward the backrest section 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, and the seat circuit board 421 slides with the seat body 11. The drive mechanism 41 pivots as the seat body 11 slides, thereby preventing the wires between the drive mechanism 41 and the seat circuit board 421 from becoming entangled. Furthermore, the drive mechanism 41 is located outside the reach of the second wire 133a between the slip ring 133 and the seat circuit board 421, thus preventing the second wire 133a between the slip ring 133 and the seat circuit board 421 from becoming entangled on the drive mechanism 41.

[0221] The implementation method for adjusting the tilt angle of the seat body in this embodiment can also be applied to the first, second, and fourth embodiments.

[0222] Fourth embodiment

[0223] The fourth embodiment of the present invention provides a child vehicle, wherein the child vehicle is, for example, a child safety seat 100a, a stroller, etc. The following description uses the child safety seat 100a as an example. Unless otherwise specified, the structure of the child safety seat 100a provided in this fourth embodiment can be referenced to the child safety seats described in the above embodiments.

[0224] The Child Safety Seat 100a can be secured to a car seat using its own ISOFIX connectors, top strap (also known as a top tether), or via the car's seatbelt. The Child Safety Seat 100a can be installed forward-facing or rear-facing. When installed forward-facing, it is generally suitable for older children. For younger children, the Child Safety Seat 100a typically needs to be installed rear-facing.

[0225] Figures 36 to 40 show structural schematic diagrams of a child safety seat 100a according to a fourth embodiment of the present invention. Figure 36 shows a perspective view of the child safety seat 100a. Figure 37 shows a side view of the child safety seat 100a in Figure 36 with the seat assembly 500 in the forward-facing use position. Figure 38 shows a side view of the child safety seat 100a in Figure 36 with the seat assembly 500 in the rearward-facing use position. Figure 39 shows a cross-sectional view along U1-U1 of the child safety seat 100a in Figure 36 with the seat assembly 500 in the forward-facing use position. Figure 40 shows a cross-sectional view along U1-U1 of the child safety seat 100a in Figure 36 with the seat assembly 500 in the rearward-facing use position.

[0226] As shown in Figures 36 to 38, the child safety seat 100a includes a base assembly 600 and a seat assembly 500 rotatably disposed 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 and the mounting seat 520 are non-detachably connected. In some alternative embodiments, the mounting seat 520 and the seat body 510 are, for example, detachably connected (not shown in the figures), which is not limited herein. The mounting seat 520 is rotatable relative to the base assembly 600 about a rotation axis X3-X3, thereby causing the seat body 510 disposed thereon to rotate about the rotation axis X3-X3, so that the seat body 510 can be switched between a forward-facing use position and a rearward-facing use position.

[0227] The child safety seat 100a may also be equipped with an anti-misuse structure 700, which is used to prevent the child safety seat 100a from being improperly installed forward-facing. Specifically, the anti-misuse structure 700 is used to prevent the seat assembly 500 of the child safety seat 100a from being incorrectly locked in the forward-facing position when a younger child is sitting in the child safety seat 100a. It should be noted that "forward-facing position" means that the seat assembly 500 is in a forward-facing position, with its back to the back of the car seat and the child sitting in the seat assembly 500 facing forward of the vehicle. "Rear-facing position" means that the seat assembly 500 is in a rear-facing position, with its back to the back of the car seat and the child sitting in the seat assembly 500 facing backward of the vehicle.

[0228] In some embodiments, the mounting base 520 is formed, for example, as part of the seat assembly 500. Referring both to Figures 39 and 40, a receiving space 501 is formed between the seat body 510 and the mounting base 520, for example. In some embodiments, the mounting base 520 and the seat body 510 may be slidably connected relative to each other, such that the tilt angle of the seat body 510 can be adjusted. The sliding connection structure between the mounting base 520 and the seat body 510 can be seen, for example, as the sliding connection structure between the rotating member 13 and the seat body 11 in the third embodiment described above.

[0229] In some alternative embodiments, the seat assembly 500 is detachably connected, for example, to a mounting base 520 (not shown), which is rotatably disposed on and formed as part of the base assembly 600, and the invention is not limited thereto.

[0230] It should also be noted that, unless otherwise explicitly specified and limited, the directional terms such as "front," "rear," "up," "down," "left," and "right" used in the various embodiments of the present invention regarding the child safety seat 100a are based on the "front," "rear," "up," "down," "left," and "right" orientations when the child safety seat 100a is installed forward-facing in the car seat and the car is in normal motion. Arrows L and R in the figures schematically indicate the "left" and "right" directions, and arrows F and B schematically indicate the "front" and "rear" directions. These directional terms are only used to make the description of the embodiments of the present invention clearer and are not intended to unduly limit the scope of protection of the present invention. It is understood that, because the seat assembly 500 of the child safety seat 100a has a forward-facing use position and a rearward-facing use position, the front-back, left-right, and right orientations of the seat assembly 500 itself will change depending on the use position of the seat assembly 500. Specifically, when the seat assembly 500 is in the forward-facing position, the front-back, left-right orientation of the seat assembly 500 and the front-back, left-right orientation of the base assembly 600 are consistent with the front-back, left-right orientation of the vehicle. When the seat assembly 500 is in the rear-facing position, the front-back, left-right orientation of the base assembly 600 is consistent with the front-back, left-right orientation of the vehicle, while the front-back, left-right orientation of the seat assembly 500 is opposite to them.

[0231] 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 overlap each other to form an accommodating 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, a flat surface to facilitate placement on a car seat. The first housing 611 is provided with a receiving recess 613, and the mounting base 520 is provided with a receiving protrusion 521. The receiving protrusion 521 has a generally circular cross-section. The receiving protrusion 521 is at least partially received within the receiving recess 613 and defines a rotation axis X3-X3 for the seat assembly 500 to rotate relative to the base assembly 600.

[0232] As shown in Figures 39 and 40, in some embodiments, the child safety seat 100a further includes a locking mechanism 810 disposed between the base assembly 600 and the seat assembly 500 for selectively locking the seat assembly 500 in a forward-facing or rearward-facing position.

[0233] In some embodiments, the engaging mechanism 810 includes an engaging pin 8110, a first engaging hole 8121, a second engaging hole 8122, and an engaging reset member 8130. The engaging pin 8110 is movably disposed on the seat assembly 500 and has an engaged position and an unlocked position. In the engaged position, the engaging pin 8110 extends relative to the surface of the receiving protrusion 521. In the unlocked position, the engaging pin 8110 retracts relative to the surface of the receiving protrusion 521, for example, being received within the surface of the receiving protrusion 521. The engaging reset member 8130 includes, for example, a spring disposed between the engaging pin 8110 and the seat assembly 500, which biases the engaging pin 8110 toward the engaged position; that is, the spring provides a force for the engaging pin 8110 to move toward the engaged position. The engaging pin 8110 may also cooperate with an operating member (not shown) disposed on the seat assembly 500 to drive the engaging pin 8110 toward the unlocked position via the operating member.

[0234] When the seat assembly 500 is not rotated to the forward or rearward use position, the locking pin 8110 is in the unlocked position under the pressure of the inner circumferential surface of the accommodating recess 613. When the seat assembly 500 is rotated to the forward or rearward use position, the locking pin 8110 extends from the surface of the accommodating protrusion 521 and enters the first locking hole 8121 or the second locking hole 8122, thereby moving to the locking position to lock the seat assembly 500 in the corresponding forward or rearward use position. Specifically, referring to Figure 39, when the locking pin 8110 is in the locking position and engages with the first locking hole 8121, the seat assembly 500 is locked in the forward use position. Referring to Figure 40, when the locking pin 8110 is in the locking position and engages with the second locking hole 8122, the seat assembly 500 is locked in the rearward use position. When the locking pin 8110 is in the unlocked position, the locking pin 8110 disengages from the first locking hole 8121 and the second locking hole 8122 to allow the seat assembly 500 to rotate relative to the base assembly 600.

[0235] Referring to Figure 46, a limiting wall is formed on the wall of the receiving recess 613. This limiting wall can be the inner circumferential surface (also called the inner circumferential surface or sidewall) or the bottom surface of the receiving recess 613. In this embodiment, the limiting wall is the sidewall of the receiving recess 613, that is, the inner circumferential surface of the receiving recess 613. In some alternative embodiments, the limiting wall can be the bottom surface of the receiving recess 613, which is not a limitation of the present invention.

[0236] In some embodiments, the first engaging hole 8121 and the second engaging hole 8122 are both disposed on the first housing 611 and penetrate the limiting wall of the receiving recess 613, so that the receiving recess 613 communicates with the receiving space 618. That is, the first engaging hole 8121 and the second engaging hole 8122 are disposed on the inner circumferential surface of the receiving recess 613. The first engaging hole 8121 and the second engaging hole 8122 extend radially along the receiving recess 613, respectively. In some alternative embodiments, the first engaging hole 8121 and the second engaging hole 8122 are disposed on the bottom surface of the receiving recess 613. The first engaging hole 8121 and the second engaging hole 8122 extend axially along the receiving recess 613, for example.

[0237] Referring again to Figures 39 and 40, one of the first engaging hole 8121 and the second engaging hole 8122 is located at the front of the base assembly 600, and the other is located at the rear of the base assembly 600. It should be noted that the front of the base assembly 600 refers to the portion of the base assembly 600 located before the rotation axis X3-X3, that is, the portion of the base body 610 located before the rotation axis X3-X3. The rear of the base assembly 600 refers to the portion of the base assembly 600 located after the rotation axis X3-X3. The base assembly 600 also has a left side portion located to the left of the rotation axis X3-X3 and a right side portion located to the right of the rotation axis X3-X3.

[0238] Accordingly, taking the seat assembly 500 in the forward-facing position as an example, the seat assembly 500 has a front portion located before the rotation axis X3-X3, a rear portion located after the rotation axis X3-X3, a right portion located to the right of the rotation axis X3-X3, and a left portion located to the left of the rotation axis X3-X3. It can be understood that when the seat assembly 500 is in the rearward-facing position, its front-back, left-right, and right-right orientations are opposite to those when it is in the forward-facing position.

[0239] As shown in Figures 39 and 40, in this embodiment, the first engaging hole 8121 is located at the rear of the base assembly 600, and the second engaging hole 8122 is located at the front of the base assembly 600. The engaging pin 8110 is located at the rear of the seat assembly 500. In some alternative embodiments, the first engaging hole 8121 is located at the front of the base assembly 600, the second engaging hole 8122 is located at the rear of the base assembly 600, and the engaging pin 8110 is located at the front of the seat assembly 500.

[0240] Referring again to Figures 39 and 40, the mounting base 520 is provided with an outlet 502. A locking pin 8110 is slidably disposed in the receiving space 501 and can extend at least partially out of the mounting base 520 through the outlet 502 to selectively engage with one of the first engaging hole 8121 and the second engaging hole 8122, thereby locking the seat assembly 500 in a forward-facing or rearward-facing position. More specifically, the locking pin 8110 is slidably disposed on the mounting base 520 via a locking fixing seat 540. The locking fixing seat 540 is disposed within the receiving space 501. A first receiving groove 541 is formed between the locking fixing seat 540 and the mounting base 520, and a first limiting portion 542 is provided within the first receiving groove 541. The first receiving groove 541 communicates with the locking outlet 502. The locking pin 8110 is generally pin-shaped and has a second limiting part 8111. The locking pin 8110 passes through the first receiving groove 541, and the locking pin 8110 is at least partially limited in the first receiving groove 541 by the mutual abutment of the first limiting part 542 and the second limiting part 8111. This can limit the movement stroke of the locking pin 8110, thereby controlling the length of the locking pin 8110 extending into the first locking hole 8121 or the second locking hole 8122 through the locking through-hole 502.

[0241] A locking reset member 8130 is disposed within the first receiving groove 541. The locking reset member 8130 is, for example, a compression spring. One end of the locking reset member 8130 abuts against the end of the first receiving groove 541, and the other end of the locking reset member 8130 is sleeved on the locking pin 8110 and abuts against the second limiting portion 8111. The locking reset member 8130 is adapted to bias the locking pin 8110 so that the locking pin 8110 moves toward the locking position. Thus, when the locking pin 8110 is not blocked by the side wall of the receiving recess 613, the locking pin 8110 can automatically move to the locking position under the elastic restoring force of the locking reset member 8130, so that when the seat assembly 500 is rotated into position (e.g., rotated to the rearward or forward use position), the locking pin 8110 automatically extends into the first locking hole 8121 or the second locking hole 8122 under the elastic restoring force of the locking reset member 8130 (e.g., a compression spring), thereby automatically locking the seat assembly 500 in the corresponding position.

[0242] The locking pin 8110 can be driven to the unlocking position by any suitable unlocking mechanism (not shown), meaning that the locking pin 8110 can be unlocked by any suitable unlocking mechanism. Specifically, when the unlocking mechanism is operated, it drives the locking pin 8110 to the unlocking position to allow the seat assembly 500 to rotate. When the unlocking mechanism is not operated, the locking pin 8110 moves to the locking position under the elastic restoring force of the locking reset member 8130, so that when the seat assembly 500 is rotated into position, such as to the rearward or forward use position, the locking pin 8110 automatically engages with the first locking hole 8121 or the second locking hole 8122 under the elastic restoring force of the locking reset member 8130.

[0243] As described above, an anti-misuse structure 700 is also provided between the base assembly 600 and the seat assembly 500. The anti-misuse structure 700 has an open state and a closed state. When the anti-misuse structure 700 is in the open state (i.e., the anti-misuse function of the anti-misuse structure 700 is enabled), the anti-misuse structure 700 can restrict the seat assembly 500 from turning from a predetermined lateral position to a forward-facing use position, and allows the seat assembly 500 to turn from that lateral position to a rearward-facing use position. When the anti-misuse structure 700 is in the closed state (i.e., the anti-misuse function of the anti-misuse structure 700 is not enabled), the seat assembly 500 can rotate freely relative to the base assembly 600 around the rotation axis X3-X3. By providing the anti-misuse structure 700, the rotation of the seat assembly 500 within a predetermined rotational stroke can be restricted, preventing the seat assembly 500 from mistakenly turning and locking in the forward-facing use position, thereby preventing younger children from mistakenly sitting in the forward-facing child safety seat 100a.

[0244] Referring to Figures 41 to 43 and Figure 46, in some embodiments, the anti-misuse structure 700 includes a limiting member 710, a limiting groove 720, an operating component 730, and a limiting reset member 750. Referring to Figure 46, the limiting groove 720 is disposed on the base assembly 600. The limiting groove 720 extends about the rotation axis X3-X3, and a stop 721 is provided at one end (the front end) of the limiting groove 720, and a guide surface 722 is provided at the other end (the rear end). The guide surface 722 is an inclined surface or an arc surface extending from the bottom of the limiting groove 720 to the opening of the limiting groove 720. The limiting member 710 is movably disposed on the mounting base 520 and can move between a locked position and an unlocked position.

[0245] Referring to Figures 41, 42, and 46, the limiting member 710 is located at the front of the mounting base 520, and the limiting groove 720 is located at the side of the base assembly 600. When the limiting member 710 is in the locked position (i.e., the limiting member 710 is locked with the limiting groove 720), the limiting member 710 extends into the limiting groove 720 to position the seat assembly 500 at a predetermined lateral position corresponding to the limiting groove 720. This predetermined lateral position is located between the forward use position and the rearward use position. At this time, the limiting member 710 is suitable to be stopped by the stop 721, thereby restricting the seat assembly 500 from rotating relative to the base assembly 600 from the lateral position to the forward use position, that is, restricting the seat assembly 500 from rotating relative to the base assembly 600 toward the stop 721. Since the other end of the limiting groove 720 is provided with a guide surface 722, the rotation of the seat assembly 500 from the lateral position to the rearward use position is unrestricted. Specifically, the limiting member 710 is adapted to exit the limiting groove 720 via the guide surface 722, thereby allowing the seat assembly 500 to rotate from a lateral position to a rearward use position, that is, allowing the seat assembly 500 to rotate toward the guide surface 722. In other words, when the limiting member 710 is inserted into the limiting groove 720, the seat assembly 500 is unidirectionally locked (also known as semi-locked) in the lateral position corresponding to the limiting groove 720. When the limiting member 710 is in the unlocked position, the limiting member 710 disengages from the limiting groove 720, and the limiting member is not interfered with by the limiting groove 720, so as to allow the seat assembly 500 to be arbitrarily adjusted in angle relative to the base assembly 600.

[0246] When the seat assembly 500 is locked in the lateral position, the limiting groove 720 provides resistance to the limiting member 710, allowing the seat assembly 500 to remain in that lateral position. This facilitates children's lateral entry and exit from the child safety seat 100a. When an older child is seated, the limiting member 710 needs to be released, and the seat assembly 500 rotated to the forward-facing position. When a smaller infant is placed in the seat assembly 500, there is no need to release the limiting member 710; simply rotating the seat assembly 500 in the direction of the guide surface 722 (i.e., the rearward-facing direction) will disengage the limiting member 710 from the limiting groove 720, thus removing the seat assembly 500 from the lateral position. The cooperation between the limiting member 710 and the limiting groove 720 creates an obstacle when a smaller infant is seated, preventing the seat assembly 500 from being mistakenly rotated to the forward-facing position.

[0247] It should be noted that the predetermined lateral position can be any angle position between the forward use position and the rearward use position. Specifically, when the seat assembly 500 is in the forward 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 rearward use position, the relative angle between the seat assembly 500 and the base assembly 600 is considered to be 180 degrees. The predetermined lateral position can be: 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, the relative angle between the seat assembly 500 and the base assembly 600 is greater than 180 degrees and less than 360 degrees.

[0248] Referring to Figure 46, the limiting member 710 faces the limiting wall of the receiving recess 613. As mentioned above, this limiting wall can be the inner circumferential surface or the bottom surface of the receiving recess 613. In this embodiment, the limiting member 710 faces the inner circumferential surface of the receiving recess 613, that is, the inner circumferential surface of the receiving recess 613 serves as the limiting wall. In some alternative embodiments, the limiting member 710 can face the bottom surface of the receiving recess 613, that is, the bottom surface of the receiving recess 613 serves as the limiting wall. This invention does not limit this.

[0249] Referring again to Figure 46, in some embodiments, the limiting groove 720 is disposed on the limiting wall of the receiving recess 613 and is recessed relative to the limiting wall of the receiving recess 613. The stop portion 721 is generally perpendicular to the bottom wall of the limiting groove 720, and the angle between the guide surface 722 and the bottom wall of the limiting groove 720 is an obtuse angle. The two sides of the guide surface 722 are respectively connected to the bottom wall of the limiting groove 720 and the limiting wall (more specifically, the inner circumferential surface) of the receiving recess 613.

[0250] In some embodiments, there are two limiting grooves 720, which are symmetrically distributed on the left and right sides of the base assembly 600 (more specifically, the base body 610). The predetermined lateral positions include, for example, a left-facing position with the seat assembly 500 facing left (i.e., the relative angle between the seat assembly 500 and the base assembly 600 is approximately 90 degrees) and a right-facing position with the seat assembly 500 facing right (i.e., the relative angle between the seat assembly 500 and the base assembly 600 is approximately 270 degrees).

[0251] In some embodiments, the line connecting the limiting groove 720 and the rotation axis X3-X3 of the seat assembly 500 is substantially perpendicular to the front-rear direction, such that when the limiting member is inserted into the limiting groove 720, the seat assembly 500 is limited to a predetermined lateral position perpendicular to the front-rear direction. The angle between the predetermined lateral position and its adjacent forward or rearward use position is approximately 90 degrees.

[0252] Referring to Figure 46, a resistance surface 760, a second engaging hole 8122, and a first engaging hole 8121 (not shown in Figure 46, opposite to the second engaging hole 8122) may also be formed on the receiving recess 613. The two resistance surfaces 760 are located on the left and right sides of the receiving recess 613, respectively. The two resistance surfaces 760 are, for example, located above the two limiting grooves 720. In some embodiments, the length of each resistance surface 760 along the inner circumferential surface of the receiving recess 613 is approximately 5 cm to 15 cm. Each resistance surface 760 may be composed of a series of longitudinally arranged grooves. The width of each groove is smaller than the width of the engaging pin 8110 to prevent the engaging pin 8110 from locking at the resistance surface 760. When the seat assembly 500 rotates relative to the base assembly 600 to a near-lateral position, the locking pin 8110 abuts against the resistance surface 760, increasing the resistance in the direction of rotation of the seat assembly 500 relative to the base assembly 600, thus indicating to the user that the seat assembly 500 is in a lateral position. The engagement of the locking pin 8110 and the resistance surface 760 also helps to keep the seat assembly 500 in a lateral position.

[0253] The first engaging hole 8121 and the second engaging hole 8122 are located at the front and rear of the receiving recess 613, respectively. As described above, the engaging pin 8110, through selective engagement with the first engaging hole 8121 and the second engaging hole 8122, is used to lock the seat assembly 500 in a forward-facing or rearward-facing use position. In some embodiments, the first engaging hole 8121 and the second engaging hole 8122, the limiting groove 720, and the resistance surface 760 are all located on the inner circumferential surface of the receiving recess 613, and the heights of the first engaging hole 8121, the second engaging hole 8122, and the resistance surface 760 are all higher than the height of the limiting groove 720.

[0254] As shown in Figures 39, 40, and 43, the locking pin 8110 is located at the rear of the outer peripheral surface of the accommodating protrusion 521 of the seat assembly 500, while the limiting member 710 is located at the front of the outer peripheral surface of the accommodating protrusion 521. The line connecting the two passes, for example, through the rotation axis X3-X3 of the seat assembly 500. The height of the locking pin 8110 is higher than that of the limiting member 710 to avoid interference between them. In addition, as shown in Figure 42, the accommodating protrusion 521 has flanges 770 below the locking pin 8110 and the limiting member 710 to prevent damage to the locking pin 8110 and the limiting member 710 when the seat assembly 500 shakes.

[0255] As shown in Figures 41 to 44, the limiting member 710 includes a limiting body 711 and a driving protrusion 712. The limiting body 711 is slidably mounted on the mounting base 520. The limiting body 711 includes a limiting end 713, which is used to cooperate with the limiting groove 720. The mounting base 520 is provided with a sliding groove 522 and a limiting outlet 523 communicating with the sliding groove 522. The limiting body 711 is slidably disposed in the sliding groove 522, and the limiting body 711 is adapted to extend into or out of the limiting groove 720 through the limiting outlet 523. The driving protrusion 712 protrudes from the limiting body 711 in a direction parallel to the rotation axis X3-X3 of the mounting base 520. The driving protrusion 712 is adapted to be pushed by the operating component 730 and drive the limiting body 711 to move. In this embodiment, the limiting member 710 is mounted at the receiving protrusion 521. When the limiting member 710 is in the locked position, the limiting end 713 of the limiting member 710 extends out of the receiving protrusion 521 to lock with the limiting groove 720. When the limiting member 710 is in the unlocked position, the limiting end 713 of the limiting member 710 retracts into the receiving protrusion 521.

[0256] In some alternative embodiments, the outer surface (more specifically, the outer peripheral surface) or bottom surface of the accommodating protrusion 521 is formed as a limiting wall, and a limiting groove 720 is disposed in the accommodating protrusion 521 and recessed relative to the limiting wall of the accommodating protrusion. A stop portion 721 and a guide surface 722 are respectively provided at both ends of the limiting groove 720. Specifically, a stop portion 721 is provided at one end (more specifically, the front end) of the limiting groove 720, and a guide surface 722 is provided at the other end (more specifically, the rear end). The angle between the guide surface 722 and the bottom wall of the limiting groove 720 is an obtuse angle, and both sides of the guide surface 722 are connected to the bottom wall and the limiting wall of the limiting groove 720, respectively. There are two limiting grooves 720, symmetrically distributed on the left and right sides of the accommodating protrusion 521 of the seat assembly 500. The limiting member 710 passes through the receiving recess 613 and has a limiting end 713. When the limiting member 710 is in the locked position, the limiting end 713 of the limiting member 710 extends into the receiving protrusion 521 to lock with the limiting groove 720. When the limiting member 710 is in the unlocked position, the limiting end 713 of the limiting member 710 retracts from the receiving protrusion 521.

[0257] Referring to Figures 42 and 43, in some embodiments, flange portions 770 may be formed at the front and / or rear of the outer side of the accommodating protrusion 521, respectively. The flange portions 770 are located at the lower end of the outer side of the accommodating protrusion 521, below the limiting member 710 and / or the engaging pin 8110. When the seat assembly 500 is positioned in the forward use position or the rear use position, the front flange portion and / or the rear flange portion 770 engage with the front reinforcement member 851 and / or the rear reinforcement member 852, respectively, to enhance the connection strength between the seat assembly 500 and the base assembly 600 in the forward and rear use positions.

[0258] Referring to Figures 43 and 44, in some embodiments, a limiting reset member 750 is disposed between the limiting member 710 and the mounting base 520. The limiting reset member 750 is adapted to bias the limiting member 710 to move the limiting member 710 to the locking position. Specifically, as described above, the mounting base 520 is provided with a sliding groove 522, and a limiting outlet 523 communicates with the sliding groove 522. The limiting member 710 is slidably disposed in the sliding groove 522. The limiting reset member 750 is received in the sliding groove 522, with one end of the limiting reset member 750 abutting against the limiting member 710 and the other end abutting against the end of the sliding groove 522 away from the limiting outlet 523. Thus, when the seat assembly 500 rotates to a predetermined lateral position, the limiting member 710 automatically extends out of the mounting base 520 and into the limiting groove 720 under the elastic restoring force of the limiting reset member 750.

[0259] As shown in Figures 41 to 44, the operating component 730 is operably disposed on the mounting base 520 and can switch between a first position and a second position. When the operating component 730 is in the first position, the limiting 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. At this time, the anti-misuse function of the anti-misuse structure 700 is not activated. When the operating component 730 is in the second position, the limiting member 710 is allowed to switch between the unlocked position and the locked position, and the anti-misuse function of the anti-misuse structure 700 is activated. Specifically, when the operating component 730 is in the second position and the limiting member 710 is in the locked position (i.e., the limiting member 710 extends into the limiting groove 720), the limiting member 710 is limited by the limiting groove 720, and the seat assembly 500 is positioned (i.e., unidirectionally locked) in a predetermined lateral position, thereby restricting the seat assembly 500 from turning from the predetermined lateral position to the forward use position. At the same time, the seat assembly 500 is allowed to be rotated from the predetermined lateral position to a rearward use position.

[0260] As shown in Figures 43 to 45, the operating component 730 includes an operating element 731 and a linkage element 732, with the operating element 731 connected to the linkage element 732. In this embodiment, the operating element 731 and the linkage element 732 are detachably connected, thus giving the operating element 731 and the linkage element 732 relatively simple structures, facilitating both separate manufacturing of the operating element 731 and the linkage element 732 and making it easy to assemble and disassemble the operating element 731 and the linkage element 732. In some alternative embodiments, the operating element 731 can be fixedly connected to the linkage element 732, or it can be integrally formed with the linkage element 732.

[0261] The operating member 731 is slidably disposed on the mounting base 520 and is provided with an operable operating part 7311, so as to drive the operating assembly 730 to slide between a first position and a second position by operating the operating part 7311. Referring to Figures 41 and 43, in the direction parallel to the rotation axis X3-X3, the operating member 731 is generally located above the linkage member 732. The mounting base 520 is provided with a mounting part 524 and an operating groove 525 that passes through the mounting part 524. The side of the mounting part 524 facing the rotation axis X3-X3 of the mounting base 520 is the inner surface 5241, and the inner surface 5241 of the mounting part 524 is arc-shaped. As shown in Figures 42 and 45, the operating member 731 is also provided with an arc-shaped part 7316, and the operating part 7311 is disposed on the arc-shaped surface of the arc-shaped part 7316. The arc-shaped surface of the arc-shaped part 7316 has the same curvature as the inner surface 5241 of the mounting part 524. The arc-shaped portion 7316 is slidably disposed along the inner side surface 5241, and the operating portion 7311 passes through the operating groove 525 so that the operating member 731 can be slid along the inner side surface 5241 by operating the operating portion 7311, thereby driving the linkage member 732 to slide, that is, the operating component 730 moves between the first position and the second position.

[0262] As shown in Figures 43 and 44, the linkage 732 is provided with a driving surface 7323. The driving surface 7323 is an inclined surface or an arc surface. Optionally, the inclined surface includes an inclined plane, a sawtooth inclined surface, or a stepped inclined surface, etc. The driving surface 7323 is positioned facing the rotation axis X3-X3 of the mounting base 520. One end of the driving surface 7323 is formed as a first driving end 7321, and the other end of the driving surface 7323 is formed as a second driving end 7322. The distance between the first driving end 7321 and the rotation axis X3-X3 is less than the distance between the second driving end 7322 and the rotation axis X3-X3.

[0263] When the operating component 730 is in the first position, the driving surface 7323 abuts against the limiting member 710. Specifically, the limiting member 710 abuts against the first driving end 7321, and the limiting member 710 exits the limiting groove 720, placing it in the unlocked position. When the operating component 730 is in the second position, the driving surface 7323 separates from or abuts against the limiting member 710. Specifically, the limiting member 710 abuts against the second driving end 7322 or separates from the driving surface 7323, allowing it to extend into the limiting groove 720 and switch to the locked position. Thus, the limiting member 710 is allowed to switch between the unlocked and locked positions. More specifically, when the limiting member 710 extends into or exits the limiting groove 720, it remains abutted against the driving surface 7323. During the switching of the operating component 730 between the first position and the second position, the limiting member 710 slides along the driving surface 7323 so that the limiting member 710 extends into or exits the limiting groove 720.

[0264] Referring to Figures 39 and 44, in some embodiments, the anti-misuse structure 700 may further include a positioning component 740. The positioning component 740 is used to limit the operating component 730 to a first position or a second position. The positioning component 740 includes a positioning member 741 and a positioning spring 742. The positioning member 741 is movably disposed within the mounting base 520 and has a positioning portion 7411 that can extend out of the mounting base 520. The positioning spring 742 is disposed between the positioning member 741 and the mounting base 520, and provides an elastic restoring force to the positioning member 741, allowing the positioning portion 7411 of the mounting base 520 to extend out of the mounting base 520. In some embodiments, the direction of movement of the positioning member 741 is generally parallel to the rotation axis X3-X3.

[0265] 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 protrusion 7314 is provided between the first positioning recess 7312 and the second positioning recess 7313. The positioning protrusion 7314 transitions continuously with the first positioning recess 7312 and the second positioning recess 7313. The positioning part 7411 selectively engages with one of the first positioning recess 7312 and the second positioning recess 7313 to position the operating assembly 730 in a first position or a second position. When the operating assembly 730 switches between the first position and the second position relative to the base assembly 600, the positioning part 7411 is pushed by the operating member 731 (more specifically, the positioning protrusion 7314) of the operating assembly 730 and moves away from the operating member 731 (i.e., is pushed by the operating member 731 and moves into the mounting base 520). After the positioning protrusion 7314 passes the positioning part 7411, the positioning part 7411 moves towards the operating member 731 under the elastic restoring force of the positioning spring 742, and engages with one of the first positioning recess 7312 and the second positioning recess 7313.

[0266] As shown in Figures 44 and 45, in this embodiment, the operating member 731 is located above the positioning member 741. The outer surface of the positioning part 7411 is an arc-shaped surface with a top position 7412. The positioning protrusion 7314 has a bottom position 7315. When the top position 7412 of the positioning part 7411 passes the bottom position 7315 of the positioning protrusion 7314, the positioning member 741, under the elastic restoring force of the positioning spring 742, pushes the operating member 731 to move through the arc-shaped surface of the positioning part 7411, so that the positioning part 7411 is accommodated in the first positioning recess 7312 and the second positioning recess 7313 closer to the positioning part 7411. That is, when the bottom position 7315 of the operating component 730 passes the top position 7412 of the positioning part 7411, the positioning spring 742 can automatically push the operating component 730 to move, so that the first positioning recess 7312 or the second positioning recess 7313 automatically engages with the positioning part 7411.

[0267] As shown in Figure 47, in some embodiments, the child safety seat 100a further includes an indicating mechanism 820. The indicating mechanism 820 includes an indicating device 8230, a first switch 8210, a second switch 8220, a control device 8250 (see Figure 49), and a battery 8240 (see Figure 50). Referring to Figures 50 and 51, in this embodiment, the base body 610 is provided with a receiving groove 617, which is recessed relative to the bottom surface of the base body 610. The base assembly 600 also includes a cover 620, which is closable and disposed at the opening of the receiving groove 617. When the cover 620 is closed, the side of the cover 620 facing away from the receiving groove 617 is flush with the bottom surface of the base body 610. A mounting groove 616 is provided within the receiving groove 617, and the battery 8240 is detachably disposed within the mounting groove 616. The indicator device 8230, the first switch 8210, the second switch 8220, and the control device 8250 are connected to the battery 8240 via conductive wires.

[0268] As shown in Figures 50 and 51, the cover 620 is pivotally connected to the base body 610 and can be connected to the base body 610 via a locking mechanism 630, thereby locking the cover 620 in a closed state. The cover 620 has a first side 622 and a second side 623 facing each other. The first side 622 is pivotally connected to the base body 610. The locking mechanism 630 is disposed on the base body 610 and is adapted to engage with the cover 620.

[0269] 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 a non-locked position. The engaging member 631 has an engaging end 6311. The cover 620 is provided with a locking hole 621. When the engaging member 631 is in the locked position, the engaging end 6311 extends into the locking hole 621, thereby achieving engagement between the cover 620 and the locking mechanism 630. When the engaging member 631 moves from the locked position to the non-locked position, the engaging end 6311 disengages from the locking hole 621, and the cover 620 can rotate freely relative to the base body 610 between an open state and a closed state.

[0270] In some embodiments, when the cover 620 is in the closed state, the second side 623 of the cover 620 is received in the receiving groove, and the locking hole 621 is provided on the second side 623. The engaging member 631 is slidably disposed in the base body 610 and can be operated. The engaging end 6311 can extend into the receiving groove 617 and engage with the locking hole 621. The base body 610 is provided with an operating port 6121, which is disposed in the second housing 612. The engaging member 631 has an engaging operating part 6313, which faces the operating port 6121, so as to operate the moving member 631 through the operating port 6121. More specifically, the engaging operating part 6313 extends into the operating port 6121 and can slide within the operating port 6121.

[0271] Referring to Figures 50 and 51, the locking mechanism 630 further includes a reset member 632, which is disposed within the base body 610 and abuts against the engaging member 631. The reset member 632 provides an elastic restoring force to the engaging member 631, causing the engaging member 631 to move towards the locked position. That is, the reset member 632 can hold the engaging member 631 in the locked position, such that the engaging end 6311 at least partially extends into the receiving groove. In this embodiment, the engaging end 6311 is provided with a wedge-shaped surface 6312. During the closing process of the cover 620 (i.e., during the rotation of the cover 620 from the open state to the closed state), the second side 623 pushes against the wedge-shaped surface 6312, causing the engaging member 631 to move from the locked position to the non-locked position. When the cover 620 rotates to fully cover the receiving groove (i.e., the cover 620 rotates to the closed state), the locking hole 621 is aligned with the locking end 6311. Under the action of the resetting member 632, the locking member 631 moves from the non-locking position to the locking position, so that the locking end 6311 engages with the locking hole 621. In this way, the cover 620 is locked in the closed state.

[0272] As shown in Figures 47 and 49, an indicator device 8230 is disposed on the base assembly 600 and is used to indicate whether the seat assembly 500 is engaged in place. A first switch 8210 is disposed on the base assembly 600 and can be electrically connected to the indicator device 8230 via the control device 8250. The first switch 8210 is used 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 can be electrically connected to the indicator device 8230 via the control device 8250. The second switch 8220 is used to detect whether the seat assembly 500 is engaged in the rearward-facing use position. The control device 8250 generates different indicator signals based on the first switch 8210 and the second switch 8220, and the indicator device 8230 provides indication based on the different indicator 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 closing signal of the first switch 8210 and sends a first indication signal to the indication device 8230, causing the indication device 8230 to respond 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 closing signal of the second switch 8220 and sends a second indication signal to the indication device 8230, causing the indication device 8230 to respond accordingly. When the seat assembly 500 is between the forward-facing and rearward-facing use positions, both the first switch 8210 and the second switch 8220 are open, and the indication device 8230 does not indicate or respond.

[0273] In some embodiments, the indicating device 8230 includes a display screen 8231, which is, for example, a capacitive screen. The content displayed on the display screen 8231 can be different text or different colors. For example, the content displayed on the display screen 8231 includes: "less than 15 months old" and "not less than 15 months old". The display screen 8231 is disposed at the front of the base assembly 600. Specifically, the front of the base assembly 600 has a connecting seat (also called a support leg connecting part) 6122, and the connecting seat 6122 is provided with a pivotable support leg (also called a support leg) 6123. The display screen 8231 is disposed, for example, on the connecting seat 6122 and above the support leg 6123, so that the display screen 8231 can be easily observed. Of course, in other embodiments, the display screen 8231 can also be disposed at other positions of the base assembly 600, such as the left or right side of the base assembly 600, etc., and the present invention does not limit this.

[0274] In some alternative embodiments, the indicating device 8230 includes a plurality of indicator lights connected to the control device 8250. When the seat assembly 500 is in a forward-facing or rearward-facing position, the control device 8250 controls the corresponding indicator lights to illuminate to indicate the position of the seat assembly 500.

[0275] In some alternative embodiments, the indicator mechanism 820 may not be equipped with a control device 8250, and the first switch 8210 or the second switch 8220 may be able to form a closed loop with the corresponding indicator light to make the corresponding indicator light up.

[0276] In some alternative embodiments, the indicator 8230 can provide a warning sound or voice prompt indicating the position of the seat assembly 500. The control device 8250 controls the indicator 8230 to play the corresponding warning sound or voice prompt.

[0277] As shown in Figure 47, in some embodiments, the child safety seat 100a may further include a drive mechanism 830. The drive mechanism 830 includes a first drive assembly 8310 and a second drive assembly 8320. Referring to Figure 39, at least a portion of the first drive assembly 8310 is movably disposed within a first engagement hole 8121, and the first drive assembly 8310 is adapted to be pushed by an engagement pin 8110 to close a first switch 8210. At least a portion of the second drive assembly 8320 is movably disposed within a second engagement hole 8122, and the second drive assembly 8320 is adapted to be pushed by the engagement pin 8110 to close a second switch 8220. When the seat assembly 500 is in the forward-facing use position, the engagement pin 8110 engages with the first engagement hole 8121 and pushes the first drive assembly 8310 to close the first switch 8210. When the seat assembly 500 is in the rearward use position, the locking pin 8110 engages with the second locking hole 8122 and pushes against the second drive assembly 8320 to close the second switch 8220.

[0278] Referring to Figure 39, in some embodiments, a rear reinforcing member 852 is provided below the first driving assembly 8310, and a front reinforcing member 851 is provided below the second driving assembly 8320. The front reinforcing member 851 and the rear reinforcing member 852 can be metal sheets with concave arc surfaces, wherein the concave arc surfaces extend along the rotation axis X3-X3 and protrude relative to the lower edge of the accommodating recess to engage the flange 770.

[0279] Referring to Figures 39 and 47, the first drive assembly 8310 is slidably disposed within the receiving space 618 of the base. When the first engaging hole 8121 is not engaged by the engaging pin 8110, the first drive assembly 8310 extends at least partially into the first engaging hole 8121. The first drive assembly 8310 includes, for example, a first drive member 8311 and a first push member 8312. The first drive member 8311 is movably disposed on the base assembly 600 via a first fixed seat 614. The first push member 8312 is connected to the first drive member 8311 and moves with the first drive member 8311 to push the first switch 8210 to close. The moving direction of the first push member 8312 and the moving direction of the first drive member 8311 are both parallel to the extending direction of the first engaging hole 8121, and at least a portion of the first push member 8312 extends laterally from the first drive member 8311.

[0280] Specifically, a first fixing base 614 is disposed within the accommodating space 618 and connected to the second housing 612. The first fixing base 614 is provided with a first sliding groove 6141, and a first clearance groove 6142 is provided on the side wall of the first sliding groove 6141. A first switch 8210 is disposed on the first fixing base 614 and located outside the first sliding groove 6141. The first sliding groove 6141 is directly opposite to the first engaging hole 8121, and a first driving member 8311 is slidably disposed in the first sliding groove 6141. A first pushing member 8312 is connected to the first driving member 8311, and a portion of the first pushing member 8312 extends out of the first sliding groove 6141 through the first clearance groove 6142. The first driving member 8311 has a first mating end 83111. When the first engaging hole 8121 is not engaged by the engaging pin 8110, the first mating end 83111 extends into the first engaging hole 8121, the first pushing member 8312 separates from the first switch 8210, and the first switch 8210 is in the open state. At this time, the first mating end 83111 is flush with or recessed into the inner circumferential surface of the receiving recess 613. When the first engaging hole 8121 engages with the engaging pin 8110, the first mating end 83111 is pushed by the engaging pin 8110 and retracts from the first engaging hole 8121 into the first sliding groove 6141. The first pushing member 8312 moves with the first driving member 8311 and pushes the first switch 8210, causing the first switch 8210 to close.

[0281] Referring to Figure 39, the first driving member 8311 is in the shape of a pin. The first driving member 8311 has a first protrusion 83112 that protrudes laterally from its outer side surface, and a first recess 6143 is provided on the side wall of the first sliding groove 6141. The first protrusion 83112 and the first recess 6143 cooperate to limit the first driving member 8311 at least partially within the first sliding groove 6141, so as to prevent the first driving member 8311 from dislodging from the first sliding groove 6141.

[0282] As shown in Figure 47, the first abutment 8312 is, for example, a spring or a sheet, but is not limited thereto. In this way, the first abutment 8312 can partially buffer the force applied to the first switch 8210, preventing excessive external force from being transmitted to the first switch 8210 and causing damage. In some embodiments, the first abutment 8312 is detachably connected to the first drive member 8311. In other embodiments, the first abutment 8312 is fixedly connected to the first drive member 8311. Alternatively, the first abutment 8312 is integrally formed on the first drive member 8311.

[0283] Referring to Figure 39, a first reset member 8330 is provided between the first driving member 8311 and the first fixed base 614. The first reset member 8330 is adapted to bias the first driving member 8311, so that the first driving member 8311 moves to a position in which its first mating end 83111 extends into the first engaging hole 8121. Specifically, the first reset member 8330 is, for example, a compression spring. The first driving member 8311 is provided with a first receiving groove 83113, the opening of which faces the bottom wall of the first sliding groove 6141. One end of the first reset member 8330 passes through the first receiving groove 83113, and the other end abuts against the bottom wall of the first sliding groove 6141.

[0284] As shown in Figures 39 and 47, in some embodiments, the second drive assembly 8320 is slidably disposed within the receiving space 618 of the base. 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 push member 8322. The second drive member 8321 is movably disposed on the base assembly 600 via a second fixed seat 615. The second push member 8322 is connected to the second drive member 8321 and moves with the second drive member 8321 to push the second switch 8220 to close. The moving direction of the second push member 8322 and the moving direction of the second drive member 8321 are both parallel to the extending direction of the second engagement hole 8122, and at least a portion of the second push member 8322 extends laterally from the second drive member 8321.

[0285] Referring to Figure 40, specifically, the second fixing seat 615 is disposed within the accommodating space 618 and connected to the second housing 612. The second fixing seat 615 is provided with a second sliding groove 6151, and the side wall of the second sliding groove 6151 is provided with a second clearance groove (not shown in the figure). The structure of the second fixing seat 615 is generally the same as that of the first fixing seat 614, and the structure of the second clearance groove can be set with reference to the structure of the first clearance groove 6142. The second switch 8220 is disposed on the second fixing seat 615 and located outside the second sliding groove 6151. The second sliding groove 6151 is directly opposite the second engaging hole 8122, and the second driving member 8321 is slidably disposed in the second sliding groove 6151. The second pushing member 8322 is connected to the second driving member 8321, and a portion of the second pushing member 8322 extends out of the second sliding groove 6151 through the second clearance groove. The second driving member 8321 has a second mating end 83211. When the second engaging hole 8122 is not engaged by the engaging pin 8110, the second mating end 83211 extends into the second engaging hole 8122, and the second pushing member 8322 separates from the second switch 8220, so the second switch 8220 is in the open state. At this time, the second mating end 83211 is flush with or recessed into the inner circumferential surface of the receiving recess 613. When the second engaging hole 8122 engages with the engaging pin 8110, the second mating end 83211 is pushed by the engaging pin 8110 and retracts from the second engaging hole 8122 into the second sliding groove 6151. The second pushing member 8322 moves with the second driving member 8321 and pushes the second switch 8220, causing the second switch 8220 to close.

[0286] Referring to Figure 40, in some embodiments, the second drive member 8321 is in the shape of a pin. The second drive member 8321 has a second protrusion 83212 that extends laterally from its outer side, and the sidewall of the second sliding groove 6151 is provided with a second recess 6153. The second protrusion 83212 and the second recess 6153 cooperate to at least partially limit the second drive member 8321 within the second sliding groove 6151, preventing the second drive member 8321 from dislodging from the second sliding groove 6151.

[0287] As shown in Figure 47, the second abutment 8322 is, for example, a spring or a sheet, but is not limited thereto. In this way, the second abutment 8322 can partially buffer the force applied to the second switch 8220, preventing excessive external force from being transmitted to the second switch 8220 and causing damage. In some embodiments, the second abutment 8322 is detachably connected to the second drive member 8321. In other embodiments, the second abutment 8322 is fixedly connected to the second drive member 8321. Alternatively, the second abutment 8322 is integrally formed onto the second drive member 8321.

[0288] Referring to Figure 39, a second reset member 8340 is disposed between the second driving member 8321 and the second fixed base 615. The second reset member 8340 is adapted to bias the second driving member 8321, so that the second driving member 8321 moves to a position in which its second mating end 83211 extends into the second engaging hole 8122. Specifically, the second reset member 8340 is, for example, a compression spring. The second driving member 8321 is provided with a second receiving groove 83213, the opening of which faces the bottom wall of the second sliding groove 6151. One end of the second reset member 8340 passes through the second receiving groove 83213, and the other end abuts against the bottom wall of the second sliding groove 6151.

[0289] The operating principle of the child safety seat 100a equipped with the seat misuse prevention structure 700 according to the present invention is as follows.

[0290] For younger children, the child safety seat 100a needs to be used rear-facing. In this case, the anti-misuse function of the child safety seat 100a can be activated, that is, the operating component 730 of the anti-misuse structure 700 can be moved to the second position along the sliding groove 522.

[0291] When the seat assembly 500 is in the forward-facing position, the locking pin 8110 engages in the first locking hole 8121. The locking pin 8110 pushes the first drive member 8311 out of the first locking hole 8121. The first drive member 8311 drives the first push member 8312 to move, causing the first push member 8312 to push the first switch 8210 to close. This causes the display screen 8231 of the indicator device 8230 to display corresponding content. The caregiver can then determine from the content displayed on the display screen 8231 that this mode is not suitable for younger children and therefore the seat assembly 500 needs to be adjusted to the rear-facing mode.

[0292] In forward-facing use mode, when the operating component 730 moves to the second position, the limiting member 710 of the anti-misuse structure 700 is stopped by the limiting wall of the accommodating recess 613 and limited to the unlocked position. To adjust the seat assembly 500 to the rearward-facing use position, the locking pin 8110 is first released by the unlocking mechanism, which is equivalent to the locking pin 8110 being disengaged from the first locking hole 8121 by the unlocking mechanism, and then the seat assembly 500 is rotated around the rotation axis X3-X3.

[0293] During the rotation of the seat assembly 500, the locking pin 8110 is stopped by the limiting wall of the receiving recess 613 and limited to the unlocked position. When the seat assembly 500 rotates to the predetermined lateral position, the locking pin 8110 remains in the unlocked position, and the limiting member 710, when facing the limiting groove 720, extends into the limiting groove 720 under the elastic restoring force of the limiting reset member 750, so that the seat assembly 500 cannot rotate in the reverse direction. At this time, a smaller child can be placed in the seat assembly 500.

[0294] Then, the seat assembly 500 continues to rotate, and the limiting member 710 exits the limiting groove 720 along the guide surface 722 and is limited in the unlocked position by the limiting wall of the receiving recess 613. When the seat assembly 500 is rotated to the rear-facing use mode, the engaging pin 8110 is aligned with the second engaging hole 8122. Under the elastic 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 rear-facing use position. At the same time, the engaging pin 8110 pushes the second mating end 83211 of the second drive member 8321 to move and exit the second engaging hole 8122. The second drive member 8321 drives the second push member 8322 to push the second switch 8220 to close, causing the display screen 8231 to display the corresponding content. The caregiver can know from the content displayed on the display screen 8231 that the child safety seat 100a is in the correct use position.

[0295] When the anti-misuse structure 700 is activated and the seat assembly 500 is in the rearward use position, the release mechanism unlocks the locking pin 8110, allowing the seat assembly 500 to rotate from the rearward use position to a predetermined lateral position. When the seat assembly 500 rotates to the predetermined lateral position, the limiting member 710 extends into the limiting groove 720 under the elastic restoring force of the limiting reset member 750, and is stopped by the stop portion 721, thereby restricting the seat assembly 500 from rotating from the predetermined lateral position to the forward use position. At this time, the seat assembly 500 can only rotate rearward from the predetermined lateral position.

[0296] In other words, when the anti-misuse structure 700 is activated, the seat assembly 500 can rotate from the forward-facing position to any other position, but cannot rotate back to the forward-facing position from any other position, thus better preventing the child safety seat 100a from being misused. Especially in the rear-facing position, the child safety seat 100a can rotate within a certain range of motion, but cannot rotate back to the forward-facing mode, avoiding situations where caregivers mistakenly believe that the seat assembly 500 is stuck in the rear-facing mode and violently rotate the seat assembly 500, thereby improving the user experience of the child safety seat 100a.

[0297] For older children, the anti-misuse structure 700 function can be disabled. This means the operating component 730 can be moved to the first position, where the limiting member 710 abuts against the first driving end 7321 of the driving surface 7323 and is limited to the unlocked position. At this time, the seat assembly 500 can be rotated within any angle range by releasing the locking pin 8110 of the unlocking mechanism.

[0298] The anti-misuse structure 700 provided in this embodiment of the invention can also be applied to the first to third embodiments.

[0299] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0300] The embodiments described above are merely examples of several implementations of the present invention, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.
