Description

Technical Field

[0001] The utility model relates to a child safety seat, a child carrier and a canopy connection structure. Background Art

[0002] Child carriers (such as child safety seats and child strollers) are generally provided with a canopy to prevent direct sunlight and foreign objects from entering the seat body. The canopy can be manually unfolded or folded to meet the different needs of users.

[0003] In addition, in order to adapt to children of different sizes, child safety seats are usually provided with an electric angle adjustment mechanism to adjust the angle of the child safety seat. Generally, the operating device of the angle adjustment mechanism is arranged on the seat body or base of the child safety seat for easy operation. However, for a driver, such as a parent of a child, it is difficult to reach the operating device to adjust the seat angle when driving a vehicle. In addition, when the child safety seat is rotated or the seat angle is adjusted, the wires are easily entangled.

[0004] In addition, in order to meet the riding needs of children of different ages, child safety seats are set to be used both forward-facing and rear-facing.

[0120] First embodiment

[0121] Figures 1 to 3 1 shows a side view and a perspective view of a child carrier 1000 according to a first embodiment of the present invention, wherein the child carrier 1000 is provided with a canopy connection structure 300 of a child carrier according to an embodiment of the present invention (see FIG. Figure 6 More specifically, the child carrier 1000 includes a body 100, a canopy 200, and a canopy connection structure 300, and the canopy 200 is detachably mounted to the body 100 via the canopy connection structure 300. The canopy connection structure 300 will be described together with the child carrier 1000.

[0122] Depend on Figures 1 to 3It can be seen that in this embodiment, the child carrier 1000 is exemplarily described by taking a child safety seat as an example, and 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 suitable for being placed on a vehicle seat (not shown in the figure) and plugged into the ISOFIX socket of the vehicle seat through, for example, an ISOFIX plug-in. The base 12 is provided with a leg 123, the upper end of the leg 123 is pivotally connected to a connecting seat 122, and the connecting seat 122 is provided on the main body 121. The lower end of the leg 123 is used to abut against the floor inside the vehicle. The seat body 11 is rotatably mounted on the base 12 to provide a forward sitting position and a rearward sitting position for the child. Of course, in some alternative embodiments, the body 100 may also have other embodiments, for example, the seat body 11 and the base 12 may be fixedly mounted together and cannot rotate relative to each other, and the base 12 may not be provided with a leg 123.

[0123] It should be noted that the product type of the child carrier 1000 to which the canopy connection structure 300 provided in the embodiment of the utility model can be applied is not limited to the child safety seat listed in this embodiment. In some alternative embodiments, the child carrier 1000 can be, for example, a baby carrier, a child stroller, a crib, etc. It is understood that according to the change of the product type of the child carrier 1000, the implementation of the body 100 will also change accordingly.

[0124] Continue to see Figures 1 to 3 as well as Figure 6 In this embodiment, the canopy 200 is detachably mounted on the seat body 11 of the body 100, more specifically, mounted to the mounting positions 110 on both sides of the backrest shell 111 of the seat body 11. Figure 1 , Figure 4 and Figure 5 The canopy 200 includes, for example, an active support 21, a positioning support 22, and a tarpaulin 23 ( Figure 1 The active bracket 21 is pivotally connected to the positioning bracket 22. The positioning bracket 22 is used to be fixed to the seat body 11. The tarpaulin 23 is connected to the active bracket 21 and the positioning bracket 22 respectively.

[0125] When the canopy 200 is mounted 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 the seat body 11. The rotation of the active bracket 21 relative to the positioning bracket 22 can drive the tarpaulin 23 to unfold or fold, so that the canopy 200 has an unfolded state (see FIG. Figure 1 ) and folded state (see Figure 2 In some alternative embodiments, the canopy 200 may also have at least one intermediate state (eg, a half-open state) between the unfolded state and the folded state. Figure 1The canopy 200 may further include at least one auxiliary bracket 24 connected to the tarpaulin 23. The auxiliary bracket 24 is, for example, pivotally connected to both the positioning bracket 22 and the active bracket 21, or the auxiliary bracket 24 is only fixedly connected to the tarpaulin 23. When the canopy 200 is unfolded, the auxiliary bracket 24 is used to support the tarpaulin 23 between the active bracket 21 and the positioning bracket 22.

[0126] Continue to see Figure 4 and Figure 5 The structure of the canopy 200 shown. In this embodiment, the active bracket 21 and the positioning bracket 22 are both substantially U-shaped, for example. The active bracket 21 includes two first connecting parts 211, and the two first connecting parts 211 are located at both ends of the U-shaped structure of the active bracket 21. The positioning bracket 22 includes two second connecting parts 222, and the two second connecting parts 222 are located at both ends of the U-shaped structure of the positioning bracket 22. The two first connecting parts 211 and the two second connecting parts 222 are respectively pivoted, so that the active bracket 21 can rotate relative to the positioning bracket 22 around the rotation axis X1-X1. More specifically, taking a pair of pivoted first connecting parts 211 and second connecting parts 222 as an example, the first connecting part 211, for example, includes a cylindrical structure extending laterally, and the second connecting part 222, for example, includes a circular ring structure, and the cylindrical structure of the first connecting part 211 is sleeved in the circular ring structure of the second connecting part 222. In some alternative embodiments, the first connecting part 211 and the second connecting part 222 can also be pivoted together by other suitable structures.

[0127] See also Figure 6 The three-dimensional structure of the body 100 shown in the figure, in this embodiment, the canopy connection structure 300 includes two driving devices 31, and the two driving devices 31 are installed on both sides of the backrest shell 111 of the seat body 11. Each driving device 31 has a power output member 311, and the power output member 311 has the above-mentioned rotation axis X1-X1 (see Figure 8 ). Each power output member 311 is used to be connected to the corresponding first connecting portion 211 of the active support 21 of the canopy 200 in a non-rotatable manner. Figure 7 The functional module diagram of the control system of the canopy connection structure 300 is shown. The canopy connection structure 300 can also include a control device 32, which is signal-connected to the drive device 31 and is used to control the power output member 311 to drive the active bracket 21 to rotate around the rotation axis X1-X1, so that the canopy 200 is automatically unfolded or folded.

[0128] The child carrier 1000 provided in the embodiment of the utility model drives the active support 21 of the canopy 200 to rotate through the control device 32 and the driving device 31 to automatically unfold or fold the canopy 200, thereby realizing automatic control of the state adjustment operation of the canopy 200.

[0129] Combined with reference Figure 3 and Figure 7 In this embodiment, the control device 32 includes, for example, a printed circuit board (not shown) mounted to the connection base 122 and a control panel 321. In some alternative embodiments, the control device 32 can be disposed at any suitable position of the body 100 or at a suitable position outside the body 100.

[0130] See also Figure 3 The control panel 321 may include a plurality of operation buttons 3211, which include, but are not limited to, a start button for starting the driving device 31, a stop button for stopping the driving device 31, an unfolding state button corresponding to the unfolding state of the canopy, a folding state button corresponding to the folding state of the canopy, and an intermediate state button corresponding to the intermediate state of the canopy. The user can adjust the state of the canopy 200 at will by operating the start button and the stop button, or adjust the canopy 200 to the corresponding state by operating the buttons corresponding to different states of the canopy. In some embodiments, the control panel 321 may include a touch screen (not shown in the figure), and the user can adjust the state of the canopy 200 by clicking the indication area on the touch screen. Of course, in some embodiments, the control panel 321 can adjust the state of the canopy 200 by combining the operation buttons 3211 and the touch screen.

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

[0132] By configuring the control device 32 with a wireless communication module 322, the user is allowed to remotely adjust the state of the canopy 200. For example, in some typical usage scenarios, the user sitting in the driver's seat can adjust the state of the canopy 200 of the child carrier 1000 installed on the rear seat of the vehicle by operating the external device 39. The user does not need to leave the driver's seat during the process of adjusting the state of the canopy 200, which brings great convenience to the user.

[0133] See also Figure 8 and Fig.11The canopy connection structure 300 of this embodiment may further include a position detection device 33, which is connected to the control device 32 by signal and is used to send a position signal related to the movement position of the active bracket 21 to the control device 32. When the power output member 311 drives the active bracket 21 to a predetermined position, the control device 32 controls the driving device 31 to stop driving the active bracket 21, so that the state of the canopy 200 can be adjusted more accurately. The predetermined position of the active bracket 21 corresponds to, for example, the unfolded state, the folded state, or any intermediate state between the unfolded state and the folded state (for example, a half-open state) of the canopy 200.

[0134] Continue to see Figure 8 and Fig.11 In this embodiment, an exemplary implementation of the position detection device 33 is also shown. 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 around the power output member 311, and indirectly obtains the motion position of the active bracket 21 by detecting the rotation position of the power output member 311.

[0135] More specifically, the power output member 311 has, for example, an annular flange 3111, which is located between the photoelectric transmitter 331 and the photoelectric receiver 332. In some embodiments, the annular flange 3111 is provided with at least two detection ports 3110 along the circumferential direction. When the annular flange 3111 rotates with the power output member 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 sends a position signal to the control device 32, and the control device 32 determines whether the active bracket 21 rotates to a predetermined position according to the position signal.

[0136] Of course, the implementation and installation position of the position detection device 33 are not limited to the above examples, as long as it can detect the position signal related to the moving position of the active bracket 21. For example, in some alternative embodiments, the position detection device 33 can directly detect the moving position of the active bracket 21. In addition, the type of the position detection device 33 is not limited to the 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] See also Figure 4 and Figure 6In this embodiment, an exemplary connection method between the power output member 311 and the first connection portion 211 of the active bracket 21 is shown. As mentioned above, the first connection portion 211 has a cylindrical structure extending laterally, and the cylindrical structure has a groove 2110 extending laterally. The power output member 311 has a columnar structure suitable for inserting into the groove 2110, so that the first connection portion 211 and the power output member 311 are sleeved together. One of the peripheral wall of the groove 2110 and the outer peripheral wall of the columnar 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 are engaged with each other, which can serve as a rotation limiting mechanism 25 for limiting the relative rotation between the first connection portion 211 and the power output member 311.

[0138] Of course, in some alternative embodiments, the connection method of the power output member 311 and the first connection portion 211 is not limited to the above-mentioned sleeve connection, and the two can also be connected in a non-rotatable manner by other suitable structures. In addition, in the embodiment where the power output member 311 and the first connection portion 211 are sleeved together, the rotation limiting mechanism 25 for limiting the relative rotation between the power output member 311 and the first connection portion 211 is also not limited to the above-mentioned protrusion 251 and recess 252. For example, in some alternative embodiments, the power output member 311 and the first connection portion 211 limit the relative rotation between the two by the contacting cross-sections.

[0139] See also Figure 6 In this embodiment, a hole is provided at the mounting position 110 of the backrest shell 111, and the power output member 311 is located inside the backrest shell 111 and corresponds to the hole at the mounting position 110. When the canopy 200 is mounted on the seat body 11 of the body 100, the first connection portion 211 of the active bracket 21 extends from the hole at the mounting position 110 into the interior of the backrest shell 111 and is sleeved with the power output member 311. In some alternative embodiments, the power output member 311 may extend from the hole at the mounting position 110, and the first connection portion 211 is sleeved with the first connection portion 211 outside the backrest shell 111.

[0140] See also Figure 6 In this embodiment, the main body 100 (more specifically, the back shell 111) is provided with a snap-fit ​​hole 112, and the snap-fit ​​hole 112 is offset from the installation position 110. Figure 5, the positioning bracket 22 is provided with a locking column 221, and the locking column 221 is, for example, provided at a position adjacent to the second connecting portion 222. When the canopy 200 is mounted on the body 100, the locking column 221 is inserted into the locking hole 112, so that the relative position of the positioning bracket 22 and the body 100 can be locked. When the canopy 200 needs to be removed, the active bracket 21 and the positioning bracket 22 are laterally spread apart, and the active bracket 21 and the positioning bracket 22 are elastically deformed. The two first connecting portions 211 move in the opposite direction along the direction of the rotation axis X1-X1 to disengage from the sleeve connection with the power output member 311, and the two second connecting portions 222 move in the opposite direction along the direction of the rotation axis X1-X1 to remove the locking column 221 from the locking hole 112, so that the canopy 200 can be moved to separate the canopy 200 from the body 100. Of course, in other embodiments, the positioning bracket 22 can also be connected to the body 100 in a non-movable manner relative to each other through other suitable positioning mechanisms. For example, in some alternative embodiments, the outer contour of the back shell 111 may be formed with a positioning groove for engaging with the positioning bracket 22 .

[0141] Figures 8 to 13 The canopy connection structure 300 of this embodiment is shown in a three-dimensional view, an exploded view and a cross-sectional view of some components. The canopy connection structure 300 may also include a mounting seat 35, which is fixed to the inside of the back shell 111 of the body 100 by, for example, a fastener (not shown) passing through a through hole 350. The driving device 31 may also include a power source 313 and a transmission mechanism 312 (see Fig.12 ), the power source 313 and the transmission mechanism 312 are both mounted on the mounting seat 35. The power source 313 is used to output power, and the transmission mechanism 312 is used to transmit the power output from the power source 313 to the power output member 311. The mounting seat 35 may also be provided with a card seat 353, and the position detection device 33 is, for example, mounted on the card seat 353.

[0142] More specifically, see Fig. 9 The power source 313 is, for example, an electric motor (or motor), which is mounted on the mounting seat 35 by, for example, a fastener 3132. The power source 313 is connected to the control device 32 by signals, and the power source 313 receives the command of the control device 32 to drive the power output member 311 to rotate or stop driving the power output member 311 to rotate. The transmission mechanism 312 is, for example, a gear transmission mechanism, and the gear transmission mechanism includes a driving wheel 3123 and an output wheel 3122. The driving wheel 3123 is drivingly connected to the output shaft 3131 of the power source 313. The driving wheel 3123 is, for example, directly connected to the output shaft 3131 in a non-rotatable manner relative to each other or connected in a non-rotatable manner relative to each other through an intermediate member 3133 installed therebetween. The driving wheel 3123 and the output wheel 3122 can be directly meshed or indirectly meshed.

[0143] The output wheel 3122 and the power output member 311 are coaxially connected by a fastener 36. The fastener 36 may be, for example, a rivet or a bolt. The output wheel 3122 has a first end face tooth 3121, and the power output member 311 has a second end face tooth 3112. The first end face tooth 3121 and the second end face tooth 3112 are meshed. The power output by the power source 313 is transmitted to the output wheel 3122 via the driving wheel 3123, and is transmitted to the power output member 311 via the meshed first end face tooth 3121 and the second end face tooth 3112. The power output member 311 drives the active bracket 21 to rotate to adjust the state of the canopy 200.

[0144] Figures 10 to 13 The exemplary assembly structure of the power source 313, the transmission mechanism 312 and the power output member 311 is shown. The mounting seat 35 is provided with a first mounting hole 351, for example, and the driving wheel 3123 is drivingly connected to the output shaft 3131 of the power source 313 at the first mounting hole 351. The mounting seat 35 is also provided with a second mounting hole 352, for example, and the output wheel 3122 and the power output member 311 are coaxially connected through a fastener 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 is sleeved with the second mounting hole 352. The output wheel 3122 has a center hole 31220, and the power output member 311 has a column 3113 that is sleeved with the center hole 31220. The power output member 311 has a first stepped hole 310. The fastener 36 is sleeved in the second mounting hole 352, the center hole 31220 and the first stepped hole 310, and serves as a rotation axis of the output wheel 3122 and the power output member 311. Accordingly, the axis of the fastener 36 forms the rotation axis X1-X1 of the power output member 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 conducive to 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 protection scope of the present utility model. In addition, the first end 361 of the fastener 36 may protrude outward relative to the power output member 311 .

[0146] See also Fig.12 and Fig.13 In this embodiment, the power output member 311 is axially movable and sleeved on the fastener 36. The canopy connection structure 300 further includes an elastic member 34, which is used to apply an elastic force to the power output member 311 to press the power output member 311 against the output wheel 3122, so that the first end face teeth 3121 and the second end face teeth 3112 are kept in meshing.

[0147] Combined with reference Fig.10 and Fig.11, the first end face tooth 3121 has an inclined portion 31212, and the second end face tooth 3112 has an inclined portion 31122. When the power output member 311 is subjected to a large circumferential force from the outside, for example, the user applies a circumferential force to the active bracket 21 to manually adjust the state of the canopy 200, the power output member 311 can rotate relative to the output wheel 3122 around the fastener 36 under the action of the inclined portion 31212 and the inclined portion 31122, and move along the fastener 36 in a direction away from the output wheel 3122, so that the first end face tooth 3121 and the second end face tooth 3112 are disengaged (i.e., Fig.13 The state shown in the figure) allows 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 need to drive the output wheel 3122 to rotate, which can avoid damaging the power source 313. In some alternative embodiments, the above technical effect can also be achieved when only one of the first end face teeth 3121 and the second end face teeth 3112 is provided with an inclined portion. In addition, in some alternative embodiments, each tooth of the first end face teeth 3121 and the second end face teeth 3112 can have an arc profile to allow the user to manually adjust the state of the canopy 200.

[0148] It should be noted that by reasonably setting the shapes of the first end face teeth 3121 and the second end face teeth 3112 and 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 member 311 and the output wheel 3122 rotate synchronously without slipping.

[0149] Continue to see Fig.12 and Fig.13 In order to facilitate the installation of the elastic member 34, the first end 361 of the fastener 36 is provided with a limiting member 37, and the elastic member 34 is sandwiched between the limiting member 37 and the power output member 311. In this embodiment, the limiting member 37 and the elastic member 34 are located inside the first stepped hole 310, the limiting member 37 and the first stepped hole 310 are slidably matched, and the elastic member 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, and the first step portion 3101 is closer to the limiting member 37 than the second step portion 3102. The limiting member 37 is used to limit the axial movement stroke of the first step portion 3101. The elastic member 34 is sandwiched between the limiting member 37 and the second step portion 3102. In some alternative embodiments, the second step portion 3102 may not be provided, and the elastic member 34 is sandwiched between the limiting member 37 and the first step portion 3101.

[0150] See also Figure 8 , Fig.12 and Fig.13In this embodiment, the stopper 37 and the power output member 311 cannot rotate relative to each other. More specifically, the outer contour of the stopper 37 is concave-convexly matched with the inner contour of the first stepped hole 310 of the power output member 311. The stopper 37 has a second stepped hole 370, and the stopper 37 is sleeved on the outside of the fastener 36 through the second stepped hole 370, 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 sleeved on the fastener 36 can also be provided in the second stepped hole 370, and the washer 38 can be made of a wear-resistant material with a low friction coefficient. In some alternative embodiments, the stopper 37 is, for example, an integral structure with the fastener 36. In some alternative embodiments, the stopper 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 briefly describes the working process of the child carrier 1000 using the canopy connection structure 300 provided in the first embodiment of the present invention when adjusting the canopy state.

[0152] The child carrier 1000 is, for example, a child safety seat installed on the rear seat of a vehicle. When a user (driver or passenger in other seats) 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 (such as a mobile terminal or a central control system of the vehicle) or a control panel 321. After 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 member 311 through the transmission mechanism 312. The power output member 311 drives the active bracket 21 to rotate until the position detection device 33 detects that the power output member 311 rotates to a position (corresponding to the desired state of the canopy 200), and the control device 32 controls the power source 313 to stop outputting power. The canopy 200 is maintained in the desired state.

In the absence of conflict, the structures of the child carrier 1000 and the canopy connection structure 300 in the second embodiment can refer to the description of the first embodiment.

[0161] See also Fig.14 and Fig.15 Different from the first embodiment described above, the canopy 200 of the second embodiment may not be provided with a positioning bracket 22, and the features related to the positioning bracket 22 may be omitted accordingly. More specifically, the canopy 200 of the second embodiment includes an active bracket 21 and a tarpaulin 23, and the tarpaulin 23 is connected to the body 100 and the active bracket 21.

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

[0164] Third embodiment

[0165] refer to Figures 16 to 18 The third embodiment of the present application provides a child safety seat 100a with adjustable angle. In the absence of conflict, the structure of the child safety seat 100a provided in the third embodiment can refer to the child safety seats described in the above embodiments, and the child safety seat can also be applied with the above-mentioned canopy connection structure 300.

[0166] See also 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 of the seat body 11 relative to the base 12 (also called the tilt angle) changes as the seat body 11 slides relative to the base 12. For example, referring to Fig.17 and Fig.18 The seat body 11 slides relative to the base 12, so that the seat body 11 is tilted at an angle of Fig.17 The upright position and Fig.18 The seat body 11 can also have a plurality of tilting gears between the upright state and the lying state to meet the requirements of the personalized sitting and sleeping positions of the baby. In some embodiments, the seat body 11 can be a baby carrier.

[0167] refer to Figures 19 to 21 In one embodiment, the child safety seat 100 a further includes: a sliding rod 131 , a sliding slot 113 , a driving rod 114 and a driving mechanism 41 .

[0168] The 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. The sliding groove 113 is, for example, formed on the seat body 11. The sliding rod 131 is inserted into the sliding groove 113, and the sliding rod 131 can slide in the sliding groove 113 to guide the seat body 11 to slide relative to the base 12 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 around the rotation axis X2-X2, and the seat body 11 and the rotating member 13 cannot pivot relative to each other around the rotation axis X2-X2. Therefore, when the rotating member 13 pivots relative to the base 12, the seat body 11 is allowed to switch between the forward use position and the rearward use position.

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

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

[0172] Optionally, the seat body 11 and the sliding groove 113 are an integral piece, and the inner peripheral wall of the sliding groove 113 is made of plastic. Fig.21 Optionally, the seat body 11 is provided with a reinforcing rib 1122 extending along the vertical direction, and the sliding groove 113 is opened on the reinforcing rib 1122 .

[0173] See also Fig.21 In one embodiment, a reinforcement 1133 is further provided on the outer side of the sliding groove 113. The reinforcement 1133 is a sheet-like structure, more specifically a thin sheet. The reinforcement 1133 can be made of metal and fixed to the seat body 11. The reinforcement 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 reinforcement 1133 strengthens the structural strength of the sliding matching structure formed by the sliding rod 131 and the sliding groove 113, thereby preventing the sliding rod 131 from wearing the sliding groove 113 during the sliding process, thereby increasing the service life of the sliding matching structure. Optionally, the thickness of the reinforcement 1133 is less than the depth of the sliding groove 113.

[0174] The two ends of the driving rod 114 are fixedly connected to the two reinforcement members 1133 arranged on the left and right. The driving rod 114 is fixedly connected to the reinforcement members 1133 to enhance the connection strength between the driving rod 114 and the seat body 11, and prevent the driving rod 114 from failing in the fixed connection with the base 12 due to long-term reciprocating motion, thereby loosening.

[0175] For reference Fig.28 and Fig.34In 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 the drive mechanism 41. The control mechanism 42 is electrically connected to the drive mechanism 41. The control mechanism 42 is used to send a control signal 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 signal.

[0176] In one embodiment, a rotating connecting member 132 is disposed at the center of the rotating member 13, and an electric slip ring 133 is passed through the middle of the rotating connecting member 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 realized 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 is electrically connected to the operation panel 431.

[0178] refer to Fig. 9 As mentioned above, the base 12 further includes a rotating member 13, which is rotatably disposed on the base 12 and connected to the seat body 11. The rotating member 13 can rotate 360 ​​degrees relative to the base 12 along the rotation axis X2-X2, so that the seat body 11 rotates relative to the base 12, thereby adjusting the seat body 11 to face forward or backward in the direction of travel of the vehicle. As mentioned above, the driving mechanism 41 is pivotally connected to the rotating member 13.

[0179] For reference Figure 22 to Figure 25 In one embodiment, the driving mechanism 41 includes: a motor 411, a screw 412, a driving block 413, and a bracket 414. The motor 4111 is fixedly arranged on the bracket 414. The screw 412 is rotatably arranged in the bracket 414, and the motor 411 is coupled with the screw 412 to drive the screw 412 to rotate. The driving block 413 is sleeved on the screw 412 and threadedly engaged with the screw 412, and the driving block 413 is also connected to the seat body 11. More specifically, the driving block 413 is connected to the driving rod 114 of the seat body 11. The screw 412 and the driving block 413 are part of the screw nut transmission mechanism. One end of the bracket 414 is pivotally connected to the base 12, for example, pivotally connected to the base 12 through a pivot pin 415. In an embodiment in which a rotating member 13 is provided, one end of the bracket 414 is pivotally connected to the rotating member 13. The other end of the bracket 414 is a free end. Optionally, the free end of the bracket 414 is sleeved in the backrest of the seat body 11 .

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

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

[0182] For reference Fig. 22 and Fig.23 In one embodiment, as described above, the seat body 11 is provided with a driving rod 114. The driving block 413 is provided with a connecting hole 4131. The driving rod 114 passes through the connecting hole 4131, so that the driving block 413 is connected to the seat body 11. When the driving block 413 moves in the length direction of the screw rod 412, since the driving rod 114 is fitted in the connecting hole 4131, the driving block 413 drives the seat body 11 to slide relative to the base 12.

[0183] refer to Fig.24 and Fig.25 In one embodiment, the motor 411 includes an output shaft 4111, and a first tooth 41111 is provided on the outer surface of the output shaft 4111. A transmission gear 4121 is fixedly provided on the screw 412, and the transmission gear 4121 has a second tooth 41211. The motor 411 drives the screw 412 to rotate through the meshing of the first tooth 41111 and the second tooth 41211. 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, so that the screw 412 rotates, thereby realizing that the motor 411 drives the screw 412 to rotate.

[0184] Continue to refer Fig.25In one embodiment, the driving block 413 is provided with a through hole 4132 with an internal thread, the through hole 4132 is sleeved on the screw rod 412, and the internal thread of the through hole 4132 is meshed with the external thread 4122 of the screw rod 412. Through the meshing of the internal thread and the external thread 4122, and through a suitable structure to limit the rotation of the driving block 413 around the axis of the screw rod 412, the rotation of the screw rod 412 can drive the driving block 413 to move in the length direction of the screw rod 412. Specifically, the motor 411 drives the screw rod 412 to rotate, and the rotation of the screw rod 412 drives the driving block 413 to move in the length direction of the screw rod 412. The movement of the driving block 413 can be transmitted to the driving rod 114, and the driving rod 114 drives the seat body 11 to slide relative to the base 12.

[0185] refer to Figure 22 to Figure 24 In one embodiment, the bracket 414 is provided with a receiving groove 4142, and the two opposite ends of the receiving groove 4142 are respectively provided with a first mounting groove 41421 and a second mounting groove 41422, and the screw rod 412 is rotatably disposed in the receiving groove 4142. The driving block 413 is embedded in 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 can limit the rotation of the driving block 413 around the axis of the screw rod 412.

[0186] See also Fig.24 , the two opposite ends of the screw rod 412 are respectively sleeved with a first support member 4123 and a second support member 4124, and the first support member 4123 and the second support member 4124 are respectively arranged in the first mounting groove 41421 and the second mounting groove 41422. When the screw rod 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. Optionally, the first support member 4123 and the second support member 4124 are made of wear-resistant materials such as steel and copper.

[0187] See also Fig.23 In one embodiment, a first cover plate 4143 is disposed at a portion of the first mounting groove 41421 of the bracket 414, and the first cover plate 4143 covers the first mounting groove 41421 to restrict the first support member 4123 in the first mounting groove 41421; a second cover plate 4144 is disposed at a portion of the second mounting groove 41422 of the bracket 414, and the second cover plate 4144 covers the second mounting groove 41422 to restrict the second support member 4124 in 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] refer to Fig. 22In one embodiment, a plurality of position sensors 4141 are provided on the bracket 414. Optionally, the plurality of position sensors 4141 are arranged on the bracket 414 at intervals along the length direction of the screw rod 412. The driving block 413 is provided with a detection sheet 4133, for example, the detection sheet 4133 is a thin sheet extending from the driving block 413, and the detection sheet 4133 protrudes from the bracket 414. When the driving block 413 moves in the length direction of the screw rod 412 until the detection sheet 4133 enters the sensing area of ​​the position sensor 4141, the position sensor 4141 sends an identification signal to the control mechanism 42, and the identification signal is related to the inclination angle of the seat body 11.

[0189] See also Fig.19 and Fig. 22 Optionally, a first position sensor 4141a and a third position sensor 4141c are respectively provided at the upper limit position and the lower limit position of the motion stroke of the support 414 corresponding to the driving block 413. The terms "upper limit position" and "lower limit position" herein refer to: Fig.19 and Figure 22-Figure 25 The “upper limit position” corresponds to the upper limit position of the upward movement of the driving block 413 and the “lower limit position” corresponds to the lower limit position of the downward movement of the driving block 413. Optionally, a second position sensor 4141b is provided at the portion of the bracket 414 corresponding to the middle position of the movement stroke of the driving block 413. The term “middle position” herein refers to: Figure 8 The middle direction is used as a reference, and is approximately the midpoint position between the limit position of the upward movement of the driving block 413 and the limit position of the downward movement of the driving block 413 .

[0190] refer to Fig.19 and Fig. 22 In one embodiment, the driving block 413 may also be provided with a limit member 4134, and the limit member 4134 protrudes from the driving block 413 in the direction of movement of the driving block 413. When the driving block 413 reaches the upper limit position or the lower limit position of the movement stroke, the limit member 4134 abuts against the bracket 414 or a suitable structure of the rotating member 13, so as to prevent the driving block 413 from continuing to move in the direction away from the upper limit position or the lower limit position. For example, in the case where the control mechanism 42 fails, the driving block 413 continues to move in the direction away from the upper limit position and the lower limit position after reaching the lower limit position of the movement stroke. At this time, the limit member 4134 will abut against the corresponding part of the bracket 414 to prevent the driving block 413 from continuing to move, thereby avoiding damage to the driving mechanism 41.

[0191] In this embodiment, the stopper 4134 protrudes from the driving block 413 in the direction of the motor 411 to prevent the driving block 413 from colliding with and damaging the motor when moving toward the motor 411. Optionally, the stopper 4134 is a protrusion extending toward the upper limit position or the lower limit position provided on the driving block 413. Optionally, the stopper 4134 is integrally formed with the driving block 413. Optionally, the stopper 4134 is fixedly connected to the driving block 413. Optionally, the stopper 4134 is provided on the side of the driving block 413 toward the lower limit position.

[0192] For reference Fig.19 and Fig.21 In one embodiment, a support plate 135 is fixedly connected to the rotating member 13. A sliding rod 131 is inserted through two left and 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 the sliding rod 131 slides in the sliding groove 113 to guide the sliding of the seat body 11 relative to the base 12, thereby changing the tilt angle of the seat body 11.

[0193] Specifically, in this embodiment, the rotating member 13 is provided with two sliding rods parallel to each other, 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, wherein the first sliding groove group 1131 includes two sliding grooves 113 arranged opposite to each other. The second sliding groove group 1132 includes another two sliding grooves 113 arranged opposite to each other. The first sliding rod 1311 is inserted into the first sliding groove group 1131, and the first sliding rod 1311 slides in the first sliding groove group 1131. The second sliding rod 1312 is inserted into the second sliding groove group 1132, and the second sliding rod 131 slides in the second sliding groove group 1132.

[0194] Optionally, a reinforcement piece 1133 is covered outside the sliding groove 113 to reduce the wear between the sliding rod 131 and the sliding groove 113. Specifically, the reinforcement piece 1133 is a sheet structure made of metal, and a through groove 11331 is provided on the reinforcement piece, and the through groove 11331 is arranged to overlap with the sliding groove 113. In this embodiment, the sliding groove 113 is integrally formed on the seat body 11, so that the sliding groove 113 is formed by the plastic material of the seat body 11. The sliding groove 113 can be directly formed on the protruding structure in the mold cavity during the molding process of the seat body 11, such as on the reinforcement rib, or it can be obtained by drilling after the molding of the seat body 11 is completed. 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 force. When the sliding rod 131 slides in the sliding groove 113, the sliding groove 113 made of plastic material helps to reduce the noise generated when the sliding rod 131 slides. Further, since the sliding groove 113 is formed of the plastic material of the seat body 11, the manufacturing cost is low.

[0195] As described above, in some embodiments, a metal reinforcement piece 1133 is provided at each sliding groove 113, and a through groove 11331 is provided on the reinforcement piece, and the through groove 11331 is adapted to the shape of the sliding groove 113. Each sliding rod 131 is slidably matched with the corresponding sliding groove 113 and the through groove 11331, so that the wear between the sliding rod 131 and the sliding groove 113 can be reduced. Furthermore, the structural strength of the sliding groove 113 is ensured by providing the reinforcement piece.

[0196] Compared with the solution of setting the sliding groove 113 on the mounting seat 13 and setting the sliding rod 131 on the seat body 11, the sliding groove 113 of this embodiment can be integrally formed with the seat body 11, and the sliding groove can have sufficient structural strength without being formed on the metal part. The structural strength of the sliding groove is further enhanced by the reinforcement 1133. The solution of this embodiment can also reduce the weight and cost of the child safety seat 100a.

[0197] Optionally, the shape of the sliding slot 113 is set to be an arc, so that the seat body 11 slides along an arc-shaped sliding track relative to the base 12. As described above, one end of the bracket 414 is pivotally connected to the base 12 through the pivot pin 415, so that the movement direction of the driving block 413 is consistent with the shape direction of the sliding slot 113. While the driving block 413 pushes the driving rod 114 to move, the driving block 413 swings around the pivot point between the bracket 414 and the rotating member 13 together with the bracket 414 to adapt to the sliding of the seat body 11 relative to the rotating member 13.

[0198] Combine the following Figures 17 to 19 as well as Figure 21 to Figure 25 The working principle of a child safety seat 100 a according to an embodiment of the present application is described in detail.

[0199] like Fig.17 As shown, the angle of the seat body 11 is, for example, in an upright state. At this time, the drive block 413 is, for example, in an upper limit position. At this time, the user (for example, a driver or a passenger driving a vehicle) sends a command to the control mechanism 42 to adjust the seat (tilt) angle by pressing a control button on a remote control device 432 (described below) or an operating 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 rod 412 to rotate, and the rotation of the screw rod 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 movement tendency. Through the cooperation of the sliding rod 131 and the arc-shaped sliding groove 113, the movement tendency of the seat body 11 is realized as the sliding of the seat body 11 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 adapt to the shape of the sliding groove 113. Figure 2 The upright state shown gradually switches to Figure 3 Thus, the driver or passenger who is driving the vehicle can easily adjust the angle of the child safety seat 100a provided in the embodiment of the present application.

[0200] For reference Fig. 20 and Fig.28 In one embodiment, as described above, the rotating member 13 is provided with a circular rotating connection member 132. The rotating connection member 132 is, for example, fixedly connected to the base 12, and is pivotally connected to the rotating member 13. In some embodiments, there is a gap between the rotating connection member 132 and the rotating member 13, and the upper shell of the base 12 is rotatably clamped in the gap. The rotating member 13 is rotatably set on the base 12 through the rotating connection member 132, and the edge of the rotating connection member 132 has an annular flange, and the annular flange slides in the annular groove of the upper shell of the base. As described above, the rotating connection member 132 is also provided with an electric slip ring 133, and the electric slip ring 133 is used to maintain the electrical connection between the components set on the seat body 11 and the components set on the base 12 when the seat body 11 rotates.

[0201] refer to Fig.16 and Fig.28In 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 the control mechanism 42. The operating panel 431 includes a control button 433 for adjusting the (tilt) angle of the seat body 11. The user can control the start of the driving mechanism 41 through the control mechanism 42 by operating the tilt gear control button on the control panel 501, 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 switch button 4331 and a tilt angle button for controlling the tilt angle of the seat body 11. After pressing the switch button 4331, the tilt angle of the seat body 11 is adjusted by pressing the tilt reduction button or the tilt increase button of the control button 433. In some embodiments, the control button may also be replaced by a touch screen, a remote controller, or a mobile phone application.

[0203] refer to Fig.21 and Fig.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] For reference Fig.28 and Fig.34 In one embodiment, the seat circuit board 421 is electrically connected to the electric slip ring 133, the drive mechanism 41 and the position sensor 4141, and the operation panel 431 and the base circuit board 124 are electrically connected to the electric slip ring 133, thereby realizing the electrical connection between the control mechanism 42 and other components. Optionally, the electrical connection is realized by wire connection. In the present application, the term "electrical connection" includes a connection for transmitting electrical energy and a connection for transmitting electrical signals.

[0205] refer to Figure 30 to Figure 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 in the form of radio frequency, Bluetooth, etc., and transmit a control signal to the control mechanism 42, so that the control mechanism 42 controls the driving mechanism 41 to drive the seat body 11 to slide relative to the base 12 to change the inclination angle of the seat body 11.

[0206] Optionally, the remote control device 432 may be a remote controller that is wirelessly and communicatively connected to the control mechanism 42. The remote controller includes, for example, an upper cover 4321 and a lower cover 4322 that are detachably buckled with each other, and a battery 4323. Optionally, the upper cover 4321 and the lower cover 4322 are buckled with each other by a first latching protrusion 4327 provided on the upper cover 4321 and a second latching protrusion 4326 provided on the lower cover 4322. Optionally, the upper cover 4321 and the lower cover 4322 may also be buckled with each other by other suitable means, such as bolt connection, magnetic connection, etc., which is not limited in the present application.

[0207] See also Fig.31 Optionally, the remote controller is further provided with a disassembly opening 4325 to facilitate separation of the upper cover 4321 and the lower cover 4322 that are buckled with each other. Fig.32 and Fig.33 The upper cover 4321 and the lower cover 4322 define a receiving space 4324, and a replaceable battery 4323 is disposed in the receiving space 4324. Optionally, the remote controller is provided with a control button for switching to an upright mode and a lying mode.

[0208] For reference Fig.28 and Fig.34 One embodiment of the present application further provides a child safety seat 100a, comprising: a base 12 and a seat body 11. The base 12 comprises a rotating member 13 and a rotating connecting member 132. The rotating connecting member 132 is fixedly connected to the main part of the base 12 (not numbered in the figure, a main structure for being placed on a vehicle seat), and is pivotally connected to the rotating member 13 so that the rotating member 13 can rotate relative to the main part of the base 12. The seat body 11 is slidably connected to the rotating member 13, and the inclination 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 inclination angle of the seat body 11 relative to the base 12 can also be referred to as the inclination angle of the seat body 11 relative to the rotating member 13.

[0209] See also Fig.16 In some embodiments, the base 12 may be provided with a power input port 126 , which is connected to a vehicle power supply, for example. A power supply system (eg, a vehicle power supply) supplies power to the child safety seat 100 a 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. The rotating connecting member 132 is penetrated 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, refer to Fig.35The base circuit board 124 is electrically connected to the electric slip ring 133, for example, through a first wire 124a. The electric slip ring 133 is electrically connected to the seat circuit board 421, for example, through a second wire 133a. The seat circuit board 421 is electrically connected to the drive mechanism 41, for example, through 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 mentioned above, the driving mechanism 41 includes a motor 411 and a plurality of position sensors 4141, and the seat circuit board 421 is used to drive the motor 411 to operate or control the motor 411 to stop operating according to the signal of the position sensor 4141. The base circuit board 124 is used to supply power to the seat circuit board 421 and to send a control signal for controlling the seat (tilt) angle adjustment. For the specific structures of the driving mechanism 41, the seat circuit board 421 and the base circuit board 124, reference may be made to the driving mechanism 41, the control mechanism 42 and the operating mechanism 43 of other embodiments of the present application.

[0212] By providing 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, thereby 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 entangled.

[0213] Generally, in a child safety seat, electronic components such as motors, sensors, fans, and heating nets are usually arranged at the seat body, while the power input port 126 and the key panel are usually arranged at the base of the child safety seat. The aforementioned electronic components and the power input port are respectively connected to a control circuit board composed of a microcontroller and its peripheral circuits, and the control circuit board is usually located at the base of the child safety seat. Among them, the number of electrical connection wires between electronic components such as motors and sensors and the control circuit board is usually six to eight, and the number of electrical connection wires between electronic components such as fans and heating devices and the control circuit board is at least six. Therefore, it is necessary to pass a wiring harness consisting of six to fifteen wires between the base 12 and the seat body 11. When the seat body 11 rotates 360 degrees relative to the base or adjusts the tilt angle of the seat body 11, the wiring harness will be pulled, and it is easy for the wires to be entangled, or the wires to interfere with the movable mechanical structure inside the child safety seat shell.

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

[0215] Continue to refer Fig.35 In one embodiment, the seat body 11 includes a backrest section 1103 and a seat section 1104, and the backrest section 1103 is connected to the seat section 1104. In some embodiments, the middle section between the backrest section 1103 and the seat section 1104 is a curved surface close to 90 degrees. In some embodiments, the backrest section 1103 and the seat section 1104 together form a substantially L-shaped structure. The seat circuit board 421 is, for example, disposed 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 the second wire 133a between the electric slip ring 133 and the seat circuit board 421 is suspended in the cavity.

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

[0217] When the seat body 11 slides forward and backward relative to the base 12, the first wire 124a will not move due to the force. When the seat body 11 slides to the most forward position relative to the base 12, that is, the seat body 11 is at the position with the largest tilt angle, see Fig.35, since the distance between the electric slip ring 133 and the seat circuit board 421 (the middle section between the backrest section 1103 and the seat section 1104) is the shortest, the second wire 133a is in a relatively relaxed state. At the same time, the distance between the seat circuit board 421 and the rotating member is the 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, the seat body 11 is at the position with the smallest inclination angle, since the distance between the electric slip ring 133 and the seat circuit board 421 (the middle section between the backrest section 1103 and the seat section 1104) is the farthest, 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 member is the shortest, and the third wire 421a is in a relatively relaxed state. Therefore, in the process of the seat body 11 rotating or sliding forward and backward, the second wire 133a and the third wire 421a are not easy to interfere with each other. The cavity provides a space for accommodating the loose and drooping second wire 133a, thereby preventing the wire from being entangled or hooked on other components inside the child safety seat due to deformation.

[0218] Continue to refer Fig.35 In one embodiment, the electric slip ring 133 is configured so that the extension line of the axis of the electric slip ring 133 always intersects with the seat section 1104 of the seat body 11 during the sliding of the seat body 11 relative to the base 12. This limits the pulling direction and deformation amplitude of the wire between the electric slip ring 133 and the seat circuit board 421 when the seat body slides, and prevents the wire from being entangled on the seat circuit board 421, the electric slip ring 133, or other components inside the child safety seat.

[0219] Optionally, the seat circuit board 421 is configured so that when the seat body 11 slides relative to the base 12, the projection of the seat circuit board 421 on the base 12 always covers the electric slip ring 133. Thus, the pulling direction and deformation amplitude of the wire between the electric slip ring 133 and the seat circuit board 421 when the seat body 11 slides are further limited, and the wire is prevented from being entangled on the seat circuit board 421, the electric slip ring 133 or other components inside the child safety seat.

[0220] Continue to refer Fig.35In this embodiment, as mentioned above, the driving mechanism 41 is arranged on the rotating member 13 and extends in the direction of the backrest section 1103 of the seat body 11. The seat circuit board 421 is electrically connected to the driving mechanism 41, for example, through the third wire 421a. The driving mechanism 41 is arranged on the rotating member 13, and the seat circuit board 421 slides with the seat body 11. The driving mechanism 41 pivots with the sliding of the seat body 11, thereby preventing the wires between the driving mechanism 41 and the seat circuit board 421 from being entangled. Furthermore, the driving mechanism 41 is located outside the reach of the second wire 133a between the electric slip ring 133 and the seat circuit board 421, thereby preventing the second wire 133a between the electric slip ring 133 and the seat circuit board 421 from being entangled on the driving 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 carrier, wherein the child carrier is, for example, a child safety seat 100a, a child stroller, etc. The following description is made by taking the child carrier as the child safety seat 100a as an example. In the absence of conflict, the structure of the child safety seat 100a provided in the fourth embodiment can refer to the child safety seats described in the above embodiments.

[0224] The child safety seat 100a can be fixed to the car seat by, for example, its own ISOFIX connector, upper strap (also called top strap) and other structures, or fixed to the car seat by the car seat belt configured by the car. The child safety seat 100a can be installed on the car seat in a forward direction or in a rearward direction. When the child safety seat 100a is installed in a car seat in a forward direction, it is generally suitable for children of an older age group. For children of a younger age group, the child safety seat 100a generally needs to be installed in a rearward direction on the car seat.

[0225] Figures 36 to 40 FIG. 1 is a schematic diagram showing the structure of a child safety seat 100a according to a fourth embodiment of the present invention. Fig.36 A perspective view of a child safety seat 100 a is shown. Fig.37 Show Fig.36 1 is a side view of the child safety seat 100a in FIG. 1 with the seat assembly 500 in the forward use position. Fig.38 Show Fig.36 1 is a side view of the child safety seat 100a in FIG. 1 with the seat assembly 500 in the rearward-facing use position.

[0226] Fig.39Show Fig.36 FIG. 1 is a U1 - U1 cross-sectional view of the child safety seat 100a when the seat assembly 500 is in the forward use position. Fig.40 Show Fig.36 FIG. 1 is a U1 - U1 cross-sectional view of the child safety seat 100a when the seat assembly 500 is in the rearward use position.

[0227] like Figure 36 to Figure 38 As shown, 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 disposed at the bottom of the seat body 510. In some embodiments, the seat body 510 is non-detachably connected to the mounting seat 120. In some alternative embodiments, the mounting seat 520 and the seat body 510 are, for example, detachably connected (not shown in the figure), which is not limited here. The mounting seat 520 can rotate relative to the base assembly 600 around the rotation axis X3-X3, thereby driving the seat body 510 disposed thereon to rotate around the rotation axis X3-X3, so that the seat body 510 can be switched between the forward use position and the rearward use position.

[0228] The child safety seat 100a may also be provided with an anti-misuse structure 700, which is used to prevent the child safety seat 100a from being improperly installed forward. Specifically, the anti-misuse structure 700 is used to prevent the seat assembly 500 of the child safety seat 100a from being mistakenly locked in the forward use position when a child of a younger age group is sitting on the child safety seat 100a. It should be noted that the seat assembly 500 is located or locked in the "forward use position" means that the seat assembly 500 is located in the forward use position, the seat assembly 500 is facing the backrest of the car seat, and the child sitting in the seat assembly 500 faces the front of the vehicle. The seat assembly 500 is located or locked in the "rearward use position" means that the seat assembly 500 is located in the rearward use position, the seat assembly 500 is facing the backrest of the car seat, and the child sitting in the seat assembly 500 faces the rear of the vehicle.

[0229] In some embodiments, the mounting base 520 is formed as part of the seat assembly 500, for example. Fig.39 and Fig.40 , for example, a receiving space 501 is formed between the seat body 510 and the mounting seat 520. In some embodiments, the mounting seat 520 and the seat body 510 can be connected to each other in a relatively sliding manner, so that the inclination angle of the seat body 510 can be adjusted. The sliding connection structure between the mounting seat 520 and the seat body 510 can refer to the sliding connection structure between the mounting seat 13 and the seat body 11 in the third embodiment.

[0230] In some alternative embodiments, the seat assembly 500 is detachably connected to the mounting base 520 (not shown in the figure), and the mounting base 520 is rotatably disposed on the base assembly 600 and forms a part of the base assembly 600, which is not limited to the present invention.

[0231] It should also be noted that, unless otherwise clearly specified and limited, the directional terms such as "front", "rear", "up", "down", "left", "right" and the like of the child safety seat 100a in each embodiment of the present invention are based on the "front", "rear", "up", "down", "left", "right" directions when the child safety seat 100a is installed forward on the car seat and the car is driving normally. In the figure, arrows L and R are used to schematically indicate the "left" and "right" directions, and arrows F and B are used to 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 used to improperly limit the scope of protection of the present invention. It can be understood that because the seat assembly 500 of the child safety seat 100a has a forward use position and a rear use position, the front, back, left and right directions of the seat assembly 500 itself will change according to the different use positions of the seat assembly 500. Specifically, when the seat assembly 500 is in the forward use position, the front, back, left and right directions of the seat assembly 500 and the front, back, left and right directions of the base assembly 600 are consistent with the front, back, left and right directions of the vehicle. When the seat assembly 500 is in the rearward use position, the front-rear and left-right directions of the base assembly 600 coincide with the front-rear and left-right directions of the vehicle, while the front-rear and left-right directions of the seat assembly 500 are opposite thereto.

[0232] Reference Fig.39 and Fig.40 The base assembly 600 includes a base body 610, and the base body 610 includes a first shell 611 and a second shell 612. The first shell 611 and the second shell 612 cover each other and form a receiving space 618. The second shell 612 forms the bottom surface of the base body 610. The bottom surface of the base body 610 is, for example, a plane, so that it can be placed on a car seat. The first shell 611 is provided with a receiving recess 613, and the mounting seat 520 is provided with a receiving protrusion 521. The cross-section of the receiving protrusion 521 is roughly circular. The receiving protrusion 521 is at least partially accommodated in the receiving recess 613, and defines the rotation axis X3-X3 of the seat assembly 500 relative to the base assembly 600.

[0233] like Fig.39 and Fig.40 As shown, in some embodiments, the child safety seat 100a further includes a locking mechanism 810, which is disposed between the base assembly 600 and the seat assembly 500, and is used to selectively lock the seat assembly 500 in the forward use position or the rearward use position.

[0234] In some embodiments, the locking mechanism 810 includes a locking pin 8110, a first locking hole 8121, a second locking hole 8122, and a locking reset member 8130. The locking pin 8110 is movably disposed on the seat assembly 500 and has a locking position and a release position. In the locking position, the locking pin 8110 extends relative to the surface of the receiving protrusion 521. In the release position, the locking pin 8110 retracts relative to the surface of the receiving protrusion 521, for example, it is accommodated in the surface of the receiving protrusion 521. The locking reset member 8130, for example, includes a spring disposed between the locking pin 8110 and the seat assembly 500, and the spring biases the locking pin 8110 to move toward the locking position, that is, the spring provides a force for the locking pin 8110 to move toward the locking position. The locking pin 8110 can also cooperate with an operating member (not shown in the figure) disposed on the seat assembly 500 to drive the locking pin 8110 to move toward the release position through the operating member.

[0235] When the seat assembly 500 is not rotated to the forward use position or the rearward use position, the locking pin 8110 is located at the unlocking position under the pressure of the inner circumferential surface of the receiving recess 613. When the seat assembly 500 is rotated to the forward use position or the rearward use position, the locking pin 8110 extends from the surface of the receiving protrusion 521 and extends into 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 use position or the corresponding rearward use position. For details, see Fig.39 When the engaging pin 8110 is located at the engaging position and engages with the first engaging hole 8121, the seat assembly 500 is locked in the forward use position. Fig.40 When the locking pin 8110 is located at the locking position and is engaged with the second locking hole 8122, the seat assembly 500 is locked in the rearward use position. When the locking pin 8110 is located at the unlocking position, the locking pin 8110 is disengaged 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.

[0236] Reference Fig.46 The limiting wall is formed on the wall of the containing recess 613, and the limiting wall may be the inner circumferential surface (also called inner circumferential surface or side wall) or the bottom surface of the containing recess 613. In this embodiment, the limiting wall is the side wall of the containing recess 613, that is, the inner circumferential surface of the containing recess 613. In some alternative embodiments, the limiting wall may be the bottom surface of the containing recess 613, which is not limited by the present invention.

[0237] In some embodiments, the first engaging hole 8121 and the second engaging hole 8122 are both provided in the first housing 611 and penetrate the limiting wall of the accommodating recess 613, so that the accommodating recess 613 is communicated with the accommodating space 618. That is, the first engaging hole 8121 and the second engaging hole 8122 are provided on the inner circumferential surface of the accommodating recess 613. The first engaging hole 8121 and the second engaging hole 8122 extend along the radial direction of the accommodating recess 613, respectively. In some alternative embodiments, the first engaging hole 8121 and the second engaging hole 8122 are provided on the bottom surface of the accommodating recess 613. The first engaging hole 8121 and the second engaging hole 8122 extend along the axial direction of the accommodating recess 613, for example, respectively.

[0238] Continue to refer to Fig.39 and Fig.40 , one of the first engaging hole 8121 and the second engaging hole 8122 is disposed at the front of the base assembly 600, and the other of the first engaging hole 8121 and the second engaging hole 8122 is disposed 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.

[0239] Accordingly, taking the seat assembly 500 in the forward use position as an example, the seat assembly 500 has a front portion located in front of the rotation axis X3-X3, a rear portion located behind the rotation axis X3-X3, a right portion located on the right side of the rotation axis X3-X3, and a left portion located on the left side of the rotation axis X3-X3. It can be understood that when the seat assembly 500 is in the rearward use position, the front-back, left-right directions of the seat assembly 500 are opposite to those when the seat assembly 500 is in the forward use position.

[0240] like Fig.39 and Fig.40 As shown, in this embodiment, the first engaging hole 8121 is disposed at the rear of the base assembly 600, and the second engaging hole 8122 is disposed at the front of the base assembly 600. The engaging pin 8110 is disposed at the rear of the seat assembly 500. In some alternative embodiments, the first engaging hole 8121 is disposed at the front of the base assembly 600, the second engaging hole 8122 is disposed at the rear of the base assembly 600, and the engaging pin 8110 is disposed at the front of the seat assembly 500.

[0241] Continue to refer to Fig.39 and Fig.40, the mounting seat 520 is provided with a through-hole 502, and the engaging pin 8110 is slidably provided in the accommodating space 501 and can at least partially extend out of the mounting seat 520 through the through-hole 502 to selectively engage with one of the first engaging hole 8121 and the second engaging hole 8122, so as to lock the seat assembly 500 in the forward use position or the rearward use position. More specifically, the engaging pin 8110 is slidably provided on the mounting seat 520 through the engaging fixing seat 540. The engaging fixing seat 540 is provided in the accommodating space 501. A first accommodating groove 541 is formed between the engaging fixing seat 540 and the mounting seat 520, and a first limiting portion 542 is provided in the first accommodating groove 541. The first accommodating groove 541 is communicated with the engaging through-hole 502. The engaging pin 8110 is generally pin-shaped and is provided with a second limiting portion 8111. The engaging pin 8110 is inserted into the first receiving groove 541, and the engaging pin 8110 is at least partially limited in the first receiving groove 541 by the mutual contact between the first limiting portion 542 and the second limiting portion 8111. In this way, the moving stroke of the engaging pin 8110 can be limited, thereby controlling the length of the engaging pin 8110 extending through the engaging hole 502 into the first engaging hole 8121 or the second engaging hole 8122.

[0242] The locking reset member 8130 is disposed in 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 suitable for biasing the locking pin 8110 to move the locking pin 8110 to the locking position. In this way, when the locking pin 8110 is not blocked by the side wall of the accommodating 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 place (for example, rotated to the rear use position or the 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 (for example, a compression spring), thereby automatically locking the seat assembly 500 in the corresponding position.

[0243] The engaging pin 8110 can be driven to the unlocking position by any suitable unlocking mechanism (not shown), which means that the engaging pin 8110 can be unlocked by any suitable unlocking mechanism. Specifically, when the unlocking mechanism is operated, the unlocking mechanism drives the engaging pin 8110 to move to the unlocking position to allow the seat assembly 500 to be rotated. When the unlocking mechanism is not operated, the engaging pin 8110 moves to the engaging position under the elastic restoring force of the engaging reset member 8130, so that when the seat assembly 500 is rotated to the position, for example, to the rearward use position or the forward use position, the engaging pin 8110 automatically engages with the first engaging hole 8121 or the second engaging hole 8122 under the elastic restoring force of the engaging reset member 8130.

[0244] As can be seen from the 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 limit the seat assembly 500 from turning from a predetermined lateral position to a forward use position, and allow the seat assembly 500 to turn from the lateral position to a rearward 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 arbitrarily around the rotation axis X3-X3 relative to the base assembly 600. By providing the anti-misuse structure 700, the rotation of the seat assembly 500 within a predetermined rotation range can be limited, and the seat assembly 500 can be prevented from being mistakenly turned and locked in the forward use position, thereby preventing children of younger age groups from mistakenly sitting in the forward-mounted child safety seat 100a.

[0245] Combination Figure 41 to Figure 43 ,as well as Fig.46 As shown, in some embodiments, the anti-misuse structure 700 includes a limit member 710, a limit slot 720, an operating assembly 730 and a limit reset member 750. Fig.46 , the limiting groove 720 is provided on the base assembly 600. The limiting groove 720 extends around the rotation axis X3-X3, and a stopper 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) of the limiting groove 720. 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 provided on the mounting seat 520 and can move between a locked position and an unlocked position.

[0246] Combined with reference Fig.41 , Fig.42 and Fig.46, the limiting member 710 is located at the front of the mounting seat 520, and the limiting groove 720 is located at the side of the base assembly 600. When the limiting member 710 is located at the locking position (that is, 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, and the predetermined lateral position is located between the forward use position and the rearward use position. At this time, the limiting member 710 is suitable for being stopped by the stopping portion 721, thereby limiting the seat assembly 500 from rotating from the lateral position to the forward use position relative to the base assembly 600, that is, limiting the seat assembly 500 from rotating toward the side of the stopping portion 721 relative to the base assembly 600. 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 not restricted. Specifically, the stopper 710 is adapted to exit the stopper groove 720 through the guide surface 722, thereby allowing the seat assembly 500 to turn from the lateral position to the rearward use position, that is, allowing the seat assembly 500 to rotate toward the guide surface 722. In other words, when the stopper 710 is inserted into the stopper groove 720, the seat assembly 500 is unidirectionally locked (also referred to as semi-locked) at the lateral position corresponding to the stopper groove 720. When the stopper 710 is in the unlocking position, the stopper 710 is disengaged from the stopper groove 720, and the stopper is not interfered by the stopper groove 720, so that the seat assembly 500 can be adjusted at any angle relative to the base assembly 600.

[0247] When the seat assembly 500 is locked in a lateral position in one direction, the limiting groove 720 generates a certain resistance to the limiting member 710 so that the seat assembly 500 can be maintained in the lateral position. In this way, it is convenient for children to enter and exit the child safety seat 100a sideways. When an older child is sitting, it is necessary to release the locking limiting member 710 and rotate the seat assembly 500 to the forward use position. When a smaller infant is placed in the seat assembly 500, it is not necessary to release the locking limiting member 710. It is only necessary to forcefully rotate the seat assembly 500 in the direction of the guide surface 722 (i.e., in the backward use direction), so that the limiting member 710 can be withdrawn from the limiting groove 720, thereby disengaging the seat assembly 500 from the lateral position. The cooperation between the limiting member 710 and the limiting groove 720 adds obstacles to the movement of the seat assembly 500 to the forward use position when a smaller infant is sitting, and effectively prevents the seat assembly 500 from being mistakenly rotated to the forward use position when a smaller infant is sitting.

[0248] It should be noted that the predetermined lateral position may 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 may 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.

[0249] Reference Fig.46 , the limiting member 710 faces the limiting wall of the containing recess 613. As can be seen from the above, the limiting wall can be the inner circumference or bottom surface of the containing recess 613. In this embodiment, the limiting member 710 faces the inner circumference of the containing recess 613, that is, the inner circumference of the containing recess 213 serves as the limiting wall. In some alternative embodiments, the limiting member 710 can face the bottom surface of the containing recess 613, that is, the bottom surface of the containing recess 213 serves as the limiting wall, and the present invention is not limited to this.

[0250] Continue to refer to Fig.46 In some embodiments, the limiting groove 720 is disposed on the limiting wall of the containing recess 613 and is recessed relative to the limiting wall of the containing recess 613. The stopper 721 is substantially perpendicular to the bottom wall of the limiting groove 720, the included angle between the guide surface 722 and the bottom wall of the limiting groove 720 is an obtuse angle, and 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 circumference) of the containing recess 613.

[0251] In some embodiments, there are two limit 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 position includes, for example, a leftward position where the seat assembly 500 faces left (i.e., the relative angle between the seat assembly 500 and the base assembly 600 is about 90 degrees) and a rightward position where the seat assembly 500 faces right (i.e., the relative angle between the seat assembly 500 and the base assembly 600 is about 270 degrees).

[0252] In some embodiments, the direction of the line between the limiting groove 720 and the rotation axis X3-X3 of the seat assembly 500 is substantially perpendicular to the front-to-back direction, so 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-to-back direction. The angle between the predetermined lateral position and the adjacent forward use position or rearward use position is approximately 90 degrees.

[0253] See also Fig.46 The accommodating recess 613 may also be formed with a resistance surface 760, a second engaging hole 8122 and a first engaging hole 8121 ( Fig.46 8122). The two resistance surfaces 760 are respectively located on the left and right sides of the accommodating recess 613. The two resistance surfaces 760 are, for example, respectively located above the two limiting grooves 720. In some embodiments, the length of each resistance surface 760 along the inner circumference of the accommodating recess 613 is about 5 cm-15 cm. Each resistance surface 760 can be composed of a series of longitudinally arranged grooves. The width of each groove is less than the width of the locking pin 8110 to avoid the locking pin 8110 from being locked at the resistance surface 760. When the seat assembly 500 rotates to a position close to the lateral position relative to the base assembly 600, the locking pin 8110 abuts against the resistance surface 760, so that the resistance of the seat assembly 500 relative to the rotation direction of the base assembly 600 becomes larger, so as to prompt the user that the seat assembly 500 is in a lateral position. The cooperation between the locking pin 8110 and the resistance surface 760 also helps to keep the seat assembly 500 in a lateral position.

[0254] The first engaging hole 8121 and the second engaging hole 8122 are respectively located at the front and rear of the receiving recess 613. As described above, the engaging pin 8110 is used to lock the seat assembly 500 in the forward use position or the rearward use position by selectively cooperating with the first engaging hole 8121 and the second engaging hole 8122. 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 circumference 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.

[0255] like Fig.39 , Fig.40 and Fig.43 As shown, the locking pin 8110 is located at the rear of the outer circumference of the accommodation protrusion 521 of the seat assembly 500, and the stopper 710 is located at the front of the outer circumference of the accommodation protrusion 521. The connecting line of the two passes through the rotation axis X3-X3 of the seat assembly 500. The height of the locking pin 8110 is higher than the stopper 710 to avoid interference with each other. In addition, in combination with Fig.42 As shown, the retaining protrusion 521 is provided with flange portions 770 below the engaging pin 8110 and the limiting member 710 , respectively, to prevent the engaging pin 8110 and the limiting member 710 from being damaged when the seat assembly 500 shakes.

[0256] like Figure 41 to Figure 44As shown, the limiting member 710 includes a limiting body 711 and a driving protrusion 712. The limiting body 711 is slidably disposed on the mounting seat 520. The limiting body 711 includes a limiting end 713, and the limiting end 713 is used to cooperate with the limiting groove 720. The mounting seat 520 is provided with a sliding groove 522 and a limiting through-port 523 connected to the sliding groove 522, and the limiting body 711 is slidably disposed in the sliding groove 522, and the limiting body 711 is suitable for extending into or exiting the limiting groove 720 through the limiting through-port 523. The driving protrusion 712 is protruded from the limiting body 711 in a direction parallel to the rotation axis X3-X3 of the mounting seat 520, and the driving protrusion 712 is suitable for being pushed by the operating assembly 730 and driving the limiting body 711 to move. In this embodiment, the limiting member 710 is disposed at the retaining protrusion 521. When the limiting member 710 is at the locking position, the limiting end 713 of the limiting member 710 extends out of the accommodation protrusion 521 to be locked with the limiting groove 720. When the limiting member 710 is at the unlocking position, the limiting end 713 of the limiting member 710 retreats into the accommodation protrusion 521.

[0257] In some alternative embodiments, the outer side surface (more specifically, the outer peripheral surface) or the bottom surface of the retaining protrusion 521 is formed as a limiting wall, and the limiting groove 720 is provided on the retaining protrusion 521 and is recessed relative to the limiting wall of the retaining protrusion. The two ends of the limiting groove 720 are respectively provided with a stopper 721 and a guide surface 722. Among them, one end (more specifically, the front end) of the limiting groove 720 is provided with a stopper 721, and the other end (more specifically, the rear end) of the limiting groove 720 is provided with a guide surface 722. The included angle between the guide surface 722 and the bottom wall of the limiting groove 720 is an obtuse angle, and the two sides of the guide surface 722 are respectively connected to the bottom wall and the limiting wall of the limiting groove 720. Among them, the number of the limiting grooves 720 is two, and the two limiting grooves 720 are symmetrically distributed on the left and right sides of the retaining protrusion 521 of the seat assembly 500. The limiting member 710 is disposed in the receiving recess 613 and has a limiting end 713. When the limiting member 710 is located at the locking 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 located at the unlocking position, the limiting end 713 of the limiting member 710 withdraws from the receiving protrusion 521.

[0258] See also Fig.42 and Fig.43In some embodiments, flanges 770 may be formed at the front and / or rear of the outer side surface of the receiving protrusion 521, respectively. The flanges 770 are located at the lower end of the outer side surface of the receiving protrusion 521 and below the stopper 710 and / or the engaging pin 8110. When the seat assembly 500 is positioned in the forward use position or the rearward use position, the front flanges and / or the rear flanges 770 are engaged with the front reinforcing plate 851 and / or the rear reinforcing plate 852 described later, respectively, to enhance the connection strength between the seat assembly 500 and the base assembly 600 in the forward and rearward use positions.

[0259] Combination Fig.43 and Fig.44 As shown, in some embodiments, the limit reset member 750 is disposed between the limit member 710 and the mounting seat 520, and the limit reset member 750 is suitable for biasing the limit member 710 to move the limit member 710 to the locking position. Specifically, as mentioned above, the mounting seat 520 is provided with a sliding groove 522, and the limit through-hole 523 is connected with the sliding groove 522. The limit member 710 is slidably disposed in the sliding groove 522. The limit reset member 750 is accommodated in the sliding groove 522, and one end of the limit reset member 750 abuts against the limit member 710, and the other end abuts against the end of the sliding groove 522 away from the limit through-hole 523. In this way, when the seat assembly 500 rotates to a predetermined lateral position, the limit member 710 automatically extends out of the mounting seat 520 and extends into the limit groove 720 under the elastic restoring force of the limit reset member 750.

[0260] like Figure 41 to Figure 44 As shown, the operating assembly 730 is operably disposed on the mounting seat 520 and can be switched between a first position and a second position. When the operating assembly 730 is located at the first position, the limiting member 710 is limited 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 enabled. When the operating assembly 730 is located at 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 enabled. Specifically, when the operating assembly 730 is located at the second position and the limiting member 710 is located at 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 at (i.e., unidirectionally locked at) a predetermined lateral position, thereby limiting 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 rotate from the predetermined lateral position to the rearward use position.

[0261] like Figure 43 to Figure 45As shown, the operating assembly 730 includes an operating member 731 and a linking member 732, and the operating member 731 is connected to the linking member 732. In this embodiment, the operating member 731 and the linking member 732 are detachably connected, so that the operating member 731 and the linking member 732 have relatively simple structures, which is convenient for manufacturing the operating member 731 and the linking member 732 separately, and is also convenient for disassembling and assembling the operating member 731 and the linking member 732. In some alternative embodiments, the operating member 731 can be fixedly connected to the linking member 732, or can be integrally formed with the linking member 732.

[0262] The operating member 731 is slidably disposed on the mounting seat 520 and is provided with an operable operating portion 7311, so that the operating assembly 730 can be driven to slide between the first position and the second position by operating the operating portion 7311. Fig.41 and Fig.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 seat 520 is provided with a mounting portion 524 and an operating slot 525 that penetrates the mounting portion 524. The side of the mounting portion 524 that faces the rotation axis X3-X3 of the mounting seat 520 is an inner side surface 5241, and the inner side surface 5241 of the mounting portion 524 is an arc shape. Fig.42 and Fig.45 As shown, the operating member 731 is further provided with an arc portion 7316, and the operating portion 7311 is provided on the arc surface of the arc portion 7316. The arc surface of the arc portion 7316 has the same curvature as the inner side surface 5241 of the mounting portion 524. The arc portion 7316 is slidably provided along the inner side surface 5241, and the operating portion 7311 is penetrated in the operating groove 525, so that the operating member 731 is driven to slide along the inner side surface 5241 by operating the operating portion 7311, thereby driving the linkage member 732 to slide, that is, the operating assembly 730 is moved between the first position and the second position.

[0263] like Fig.43 and Fig.44 As shown, 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. The driving surface 7323 is arranged facing the rotation axis X3-X3 of the mounting seat 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, wherein the distance between the first driving end 7321 and the rotation axis X3-X3 is smaller than the distance between the second driving end 7322 and the rotation axis X3-X3.

[0264] When the operating assembly 730 is located at 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, the limiting member 710 withdraws from the limiting groove 720, and the limiting member 710 is in the unlocking position. When the operating assembly 730 is located at the second position, the driving surface 7323 is separated from or abuts against the limiting member 710, specifically, the limiting member 710 abuts against the second driving end 7322 or is separated from the driving surface 7323, the limiting member 710 extends into the limiting groove 720, and the limiting member 710 can be switched to the locking position. Thus, the limiting member 710 is allowed to switch between the unlocking position and the locking position. More specifically, when the limiting member 710 extends into or withdraws from the limiting groove 720, the limiting member 710 remains in abutment with the driving surface 7323. When the operating assembly 730 switches 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 .

[0265] Combination Fig.39 and Fig.44 As shown, in some embodiments, the anti-misuse structure 700 may further include a positioning assembly 740. The positioning assembly 740 is used to limit the operating assembly 730 at the first position or the second position. The positioning assembly 740 includes a positioning member 741 and a positioning spring 742. The positioning member 741 is movably disposed in the mounting seat 520 and has a positioning portion 7411 that can extend from the mounting seat 520. The positioning spring 742 is disposed between the positioning member 741 and the mounting seat 520. The positioning spring 742 provides an elastic restoring force for the positioning member 741 so that the positioning portion 7411 of the mounting seat 520 can extend from the mounting seat 520. In some embodiments, the moving direction of the positioning member 741 is substantially parallel to the rotation axis X3-X3.

[0266] Combination Figure 43 to Figure 45As shown, 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 continuously transitions with the first positioning recess 7312 and the second positioning recess 7313. The positioning portion 7411 selectively matches with one of the first positioning recess 7312 and the second positioning recess 7313 in a concave-convex manner to position the operating assembly 730 in the first position or the second position. When the operating assembly 730 switches between the first position and the second position relative to the base assembly 600, the positioning portion 7411 is pushed by the operating member 731 of the operating assembly 730 (more specifically, the positioning protrusion 7314) and moves in a direction away from the operating member 731 (i.e., is pushed by the operating member 731 and moves into the mounting seat 520). When the positioning protrusion 7314 passes over the positioning portion 7411 , the positioning portion 7411 moves toward the operating member 731 under the elastic restoring force of the positioning spring 742 , and cooperates with one of the first positioning recess 7312 and the second positioning recess 7313 .

[0267] like Fig.44 and Fig.45 As shown, in this embodiment, the operating member 731 is located above the positioning member 741, and the outer side surface of the positioning portion 7411 is an arc surface, and the arc surface has a topmost position 7412. The positioning protrusion 7314 has a bottommost position 7315. When the topmost position 7412 of the positioning portion 7411 exceeds the bottommost position 7315 of the positioning protrusion 7314, the positioning member 741 pushes the operating member 731 to move through the arc surface of the positioning portion 7411 under the elastic restoring force of the positioning spring 742, so that the positioning portion 7411 is accommodated in the one of the first positioning recess 7312 and the second positioning recess 7313 that is closer to the positioning portion 7411. That is, when the bottom position 7315 of the operating component 730 exceeds the top position 7412 of the positioning portion 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 cooperates with the positioning portion 7411 .

[0268] like Fig.47 As shown, in some embodiments, the child safety seat 100a further includes an indication mechanism 820. The indication mechanism 820 includes an indication device 8230, a first switch 8210, a second switch 8220, a control device 8250 (see Fig.49 ) and battery 8240 (see Fig.50 ). Combined Fig.50 and Fig.51As shown, in this embodiment, the base body 610 is provided with a receiving groove 617, and the receiving groove 617 is recessed relative to the bottom surface of the base body 610. The base assembly 600 also includes a cover body 620, which is openably and closably arranged at the opening of the receiving groove 617. When the cover body 620 is in a covered state, the side of the cover body 620 facing away from the receiving groove 617 is flush with the bottom surface of the base body 610. The receiving groove 617 is provided with a mounting groove body 616, and the battery 8240 is detachably arranged in the mounting groove body 616. The indicating device 8230, the first switch 8210, the second switch 8220 and the control device 8250 are connected to the battery 8240 through conductive wires.

[0269] like Fig.50 and Fig.51 As shown, the cover body 620 is pivotally connected to the base body 610, and can be connected to the base body 610 through a locking mechanism 630, so that the cover body 620 is locked in a closed state. The cover body 620 has a first side 622 and a second side 623 opposite to 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 the locking mechanism 630 is suitable for engaging with the cover body 620.

[0270] The locking mechanism 630 includes a clamping member 631 operably arranged on the base body 610, and the clamping member 631 can move between a clamping position and an unlocking position. The clamping member 631 has a clamping end 6311. The cover body 620 is provided with a locking hole 621. When the clamping member 631 is located at the locking position, the clamping end 6311 extends into the locking hole 621, thereby realizing the clamping between the cover body 620 and the locking mechanism 630. When the clamping member 631 moves from the locking position to the unlocking position, the clamping end 6311 exits the locking hole 621, and the cover body 620 can freely rotate between the open state and the covered state relative to the base body 610.

[0271] In some embodiments, when the cover body 620 is in the covered state, the second side 623 of the cover body 620 is accommodated in the accommodating groove, and the locking hole 621 is arranged on the second side 623. The engaging member 631 is slidably arranged in the base body 610 and can be operated. The engaging end 6311 can extend into the accommodating groove 617 and engage with the locking hole 621. The base body 610 is provided with an operating port 6121, which is arranged in the second shell 612. The engaging member 631 has a engaging operating portion 6313, which is directly opposite to the operating port 6121, so as to operate the engaging member 631 to move through the operating port 6121. More specifically, the engaging operating portion 6313 extends into the operating port 6121 and can slide in the operating port 6121.

[0272] Reference Fig.50 and Fig.51The locking mechanism 630 further includes a reset member 632, which is disposed in the base body 610 and abuts against the engaging member 631. The reset member 632 provides elastic restoring force for the engaging member 631 so that the engaging member 631 moves toward the locked position. In other words, the reset member 632 can keep the engaging member 631 in the locked position so 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 body 620 (i.e., during the rotation of the cover body 620 from the open state to the closed state), the second side 623 pushes against the wedge-shaped surface 6312 to move the engaging member 631 from the locked position to the non-locked position. When the cover 620 is rotated to completely cover the receiving slot (i.e., the cover 620 is rotated to the covering state), the locking hole 621 is opposite to the locking end 6311, and the locking member 631 moves from the non-locking position to the locking position under the action of the reset member 632, so that the locking end 6311 is engaged with the locking hole 621. In this way, the cover 620 is locked in the covering state.

[0273] like Fig.47 and Fig.49 The indicating device 8230 is provided at the base assembly 600 and is used to indicate whether the seat assembly 500 is engaged in place. The first switch 8210 is provided at the base assembly 600 and can be electrically connected to the indicating device 8230 through the control device 8250. The first switch 8210 is used to detect whether the seat assembly 500 is engaged in the forward use position. The second switch 8220 is provided at the base assembly 600 and can be electrically connected to the indicating device 8230 through the control device 8250. The second switch 8220 is used to detect whether the seat assembly 500 is engaged in the rearward use position. The control device 8250 generates different indicating signals according to the first switch 8210 and the second switch 8220, and the indicating device 8230 indicates according to the different indicating signals. Specifically, when the seat assembly 500 is engaged in the forward use position, the first switch 8210 is closed and the second switch 8220 is opened. The control device 8250 receives the closing signal of the first switch 8210 and sends the first indicating signal to the indicating device 8230, so that the indicating device 8230 responds accordingly. When the seat assembly 500 is engaged in the rearward use position, the second switch 8220 is closed, the first switch 8210 is opened, the control device 8250 receives the closing signal of the second switch 8220 and sends a second indication signal to the indication device 8230, so that the indication device 8230 responds accordingly. When the seat assembly 500 is located between the forward use position and the rearward use position, the first switch 8210 and the second switch 8220 are both opened, and the indication device 8230 does not indicate or respond.

[0274] 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 may be different texts or different colors.

The display screen 8231 is, for example, arranged on the connecting seat 6122 and located 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 arranged at other positions of the base assembly 600, such as the left side or right side of the base assembly 600, etc., and the utility model is not limited to this.

[0275] In some alternative embodiments, the indicator device 8230 includes a plurality of indicator lights connected to the control device 8250. When the seat assembly 500 is located in the forward use position or the rearward use position, the control device 8250 controls the corresponding indicator lights to light up to indicate the position of the seat assembly 500.

[0276] In some alternative embodiments, the indicating mechanism 820 may not be provided with the control device 8250, and the first switch 8210 or the second switch 8220 can form a closed loop with the corresponding indicator light to light up the corresponding indicator.

[0277] In other alternative embodiments, the indicator device 8230 can use a warning sound or voice prompt to indicate the position of the seat assembly 500. The control device 8250 controls the indicator device 8230 to play the corresponding warning sound or voice prompt.

The first push member 8312 is connected to the first driving member 8311, and a part of the first push member 8312 extends out of the first sliding groove 6141 through the first avoidance 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 is separated from the first switch 8210, and the first switch 8210 is in an off state. At this time, the first mating end 83111 is flush with the inner circumference of the accommodating recess 613 or is sunken into the inner circumference of the accommodating recess 613. When the first engaging hole 8121 is engaged with the engaging pin 8110, the first mating end 83111 is pushed by the engaging pin 8110 and withdrawn from the first engaging hole 8121 into the first sliding groove 6141, and the first pushing member 8312 moves with the first driving member 8311 and pushes the first switch 8210, so that the first switch 8210 is closed.

The first driving member 8311 has a first protrusion 83112 protruding laterally from its outer side surface, and the side wall of the first sliding groove 6141 is provided with a first recess 6143. The first protrusion 83112 cooperates with the first recess 6143 to at least partially limit the first driving member 8311 in the first sliding groove 6141 to prevent the first driving member 8311 from falling out of the first sliding groove 6141.

[0283] like Fig.47 As shown, the first push member 8312 is, for example, a spring or a spring sheet, but is not limited thereto. In this way, the first push member 8312 can partially buffer the force of pressing the first switch 8210, and prevent excessive external force from being transmitted to the first switch 8210 and causing damage to the first switch 8210. In some embodiments, the first push member 8312 is detachably connected to the first drive member 8311. In other embodiments, the first push member 8312 is fixedly connected to the first drive member 8311. Alternatively, the first push member 8312 is integrally formed on the first drive member 8311.

When the second engaging hole 8122 is not engaged by the engaging pin 8110, the second drive assembly 8320 at least partially extends into the second engaging hole 8122. The second drive assembly 8320, for example, includes a second drive member 8321 and a second push member 8322. The second drive member 8321 is movably disposed on the base assembly 600 through the 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 engaging hole 8122, and at least a portion of the second push member 8322 extends laterally from the second drive member 8321.

[0286] See also Fig.40Specifically, the second fixed seat 615 is arranged in the accommodating space 618 and connected to the second shell 612. The second fixed 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 avoidance groove (not shown in the drawings). Among them, the structure of the second fixed seat 615 is substantially the same as that of the first fixed seat 614, and the structure of the second avoidance groove can refer to the structure of the first avoidance groove 2143. The second switch 8220 is arranged on the second fixed seat 615 and is located outside the second sliding groove 6151. The second sliding groove 6151 is opposite to the second engaging hole 8122, and the second driving member 8321 is slidably arranged in the second sliding groove 6151. The second push member 8322 is connected to the second driving member 8321, and a part of the second push member 8322 extends out of the second sliding groove 6151 through the second avoidance 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, the second push member 8322 is separated from the second switch 8220, and the second switch 8220 is in an off state. At this time, the second mating end 83211 is flush with the inner circumference of the accommodating recess 613 or is sunken into the inner circumference of the accommodating recess 613. When the second engaging hole 8122 is engaged with the engaging pin 8110, the second mating end 83211 is pushed by the engaging pin 8110 and withdrawn from the second engaging hole 8122 into the second sliding groove 6151, and the second push member 8322 moves with the second driving member 8321 and pushes the second switch 8220, so that the second switch 8220 is closed.

[0287] See also Fig.40 In some embodiments, the second driving member 8321 is pin-shaped. The second driving member 8321 has a second protrusion 83212 protruding laterally from the outer side thereof, and the side wall of the second sliding groove 6151 is provided with a second recess 6153. The second protrusion 83212 cooperates with the second recess 6153 to at least partially limit the second driving member 8321 in the second sliding groove 6151 to prevent the second driving member 8321 from falling out of the second sliding groove 6151.

[0288] like Fig.47 As shown, the second push member 8322 is, for example, a spring or a spring sheet, but is not limited thereto. In this way, the second push member 8322 can partially buffer the force of pressing the second switch 8220, and prevent excessive external force from being transmitted to the second switch 8220 and causing damage to the second switch 8220. In some embodiments, the second push member 8322 is detachably connected to the second drive member 8321. In other embodiments, the second push member 8322 is fixedly connected to the second drive member 8321. Alternatively, the second push member 8322 is integrally formed on the second drive member 8321.

[0289] Reference Fig.39A second reset member 8340 is provided between the second driving member 8321 and the second fixing seat 615, and the second reset member 8340 is suitable for biasing the second driving member 8321 so that the second driving member 8321 moves to a position where the second mating end 83211 of the second driving member 8321 extends into the second engaging hole 8122. Specifically, the second reset member 8340 is, for example, a compression spring, and the second driving member 8321 is provided with a second retaining groove 83213, and the opening of the second retaining groove 83213 faces the bottom wall of the second sliding groove 6151. One end of the second reset member 8340 is inserted into the second retaining groove 83213, and the other end abuts against the bottom wall of the second sliding groove 6151.

[0290] The operating principle of the child safety seat 100 a equipped with the seat anti-misuse structure 700 according to the present invention is as follows.

[0291] For children of a younger age group, the child safety seat 100a needs to be used rearward facing. At this time, the anti-misuse function of the child safety seat 100a can be enabled, that is, the operating component 730 of the anti-misuse structure 700 can be moved along the sliding groove 522 to the second position.

[0292] When the seat assembly 500 is in the forward use position, the engaging pin 8110 is engaged in the first engaging hole 8121. The engaging pin 8110 pushes the first driving member 8311 out of the first engaging hole 8121, and the first driving member 8311 drives the first pushing member 8312 to move, so that the first pushing member 8312 pushes the first switch 8210 to close, so that the display screen 8231 of the indicator device 8230 displays corresponding content. The caregiver can know from the content displayed on the display screen 8231 that this mode is not suitable for children of younger age groups, and therefore needs to adjust the seat assembly 500 to the rearward use mode.

[0293] In the forward use mode, when the operating assembly 730 moves to the second position, the limiting member 710 of the anti-misuse structure 700 is stopped by the limiting wall of the receiving recess 613 and is limited to the unlocked position. To adjust the seat assembly 500 to the rearward use position, the locking pin 8110 is first released by the locking mechanism, which is equivalent to withdrawing the locking pin 8110 from the first locking hole 8121 by the locking mechanism, and then the seat assembly 500 is rotated around the rotation axis X3-X3.

[0294] During the rotation of the seat assembly 500, the engaging pin 8110 is stopped by the limiting wall of the receiving recess 613 and is limited in the unlocking position. When the seat assembly 500 rotates to a predetermined lateral position, the engaging pin 8110 is still kept in the unlocking position, and the limiting member 710 extends into the limiting groove 720 under the elastic restoring force of the limiting reset member 750 when facing the limiting groove 720, so that the seat assembly 500 cannot rotate in the reverse direction. At this time, a small child can be placed in the seat assembly 500.

[0295] 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 unlocking position by the limiting wall of the accommodating recess 613. When the seat assembly 500 rotates to the rearward use mode, the locking pin 8110 faces the second locking hole 8122, and the locking pin 8110 extends into the second locking hole 8122 under the elastic restoring force of the locking reset member 8130, thereby locking the seat assembly 500 in the rearward use position. At the same time, the locking pin 8110 pushes the second mating end 83211 of the second driving member 8321 to move and exit the second locking hole 8122, and the second driving member 8321 drives the second pushing member 8322 to push the second switch 8220 to close, so that the display screen 8231 displays the corresponding content. The caregiver can know that the child safety seat 100a is in the correct use position according to the content displayed on the display screen 8231.

[0296] When the anti-misuse structure 700 is opened and the seat assembly 500 is in the rearward use position, the locking pin 8110 is unlocked by the release mechanism, and the seat assembly 500 can be rotated from the rearward use position to a predetermined lateral position. When the seat assembly 500 is rotated to the predetermined lateral position, the limiter 710 extends into the limiter groove 720 under the elastic restoring force of the limiter reset member 750, and the limiter 710 is stopped by the stopper 721, thereby limiting the rotation of the seat assembly 500 from the predetermined lateral position to the forward use position. At this time, the seat assembly 500 can only be rotated from the predetermined lateral position to the rearward use position.

[0297] In other words, when the anti-misuse structure 700 is opened, the seat assembly 500 can be rotated from the forward use position to any other position, but cannot be rotated from any other position to the forward use position, thereby better preventing the child safety seat 100a from being used incorrectly. In particular, in the rearward use position, the child safety seat 100a can be rotated within a certain rotation range, but cannot be rotated to the forward use mode, thereby preventing the caregiver from violently rotating the seat assembly 500 because he mistakenly believes that the seat assembly 500 is stuck in the rearward use mode, thereby improving the user experience of the child safety seat 100a.

[0298] For older children, the anti-misuse structure 700 function may not be enabled, that is, the operating assembly 730 may be moved to the first position, and the limiting member 710 abuts against the first driving end 7321 of the driving surface 7323 and is limited in the unlocking position. At this time, the locking mechanism releases the locking pin 8110, and the seat assembly 500 can be rotated in any angle range.

[0299] The anti-misuse structure 700 provided in the embodiment of the utility model can also be applied to the first to third embodiments.

[0300] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described 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.

[0301] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
