Technical Field

[0001] This application relates to the field of child safety seat technology, and in particular to a child safety seat and a child safety seat anti-accidental activation system. Prior Technology

[0002] To enhance safety and comfort, child safety seats are typically equipped with angle adjustment functions. Commercially available child safety seats can be adjusted for recline via electric and / or manual methods. However, the recline adjustment mechanisms of commercially available child safety seats are often complex in structure, have low structural strength, and are inconvenient to install.

[0003] In addition, for ease of use, child safety seats are often equipped with input components such as buttons for operating the seat. However, these input components are easily accidentally activated during use, causing various functions to be unintentionally activated, which brings inconvenience to the user. Summary of the Invention

[0017] The child safety seat provided in this application simplifies the structural complexity of the child safety seat by setting a slider that is detachably engaged with the transmission component and connected to the seat body. The transmission component is driven by a driver to move the slider, and the movement of the slider drives the seat body to slide relative to the base, thereby adjusting the seat angle. On the other hand, the engagement of the slider with the transmission component results in high transmission efficiency, simple connection method, and low installation difficulty, which helps to improve assembly efficiency.

[0018] According to another aspect of this application, an anti-accidental touch system for a child safety seat is provided. The child safety seat includes a seat body, a base, an input component, and a seat posture adjustment component. The input component includes at least one of a button or a touchscreen. The seat posture adjustment component includes at least one of a rotation position adjustment mechanism for adjusting the rotational position of the seat body and a tilt angle adjustment mechanism for adjusting the tilt angle of the seat body. The anti-accidental touch system includes: a seat posture detection module disposed on the seat body or base to detect the seat posture of the seat body; and a control module electrically connected to the input component and the seat posture detection module. The control module disables the input component in response to no change in the seat posture within a preset time, and activates the input component in response to a change in the seat posture. The seat posture includes at least one of the rotational position of the seat body and the tilt angle of the seat body.

[0019] In one embodiment, the seat posture detection module includes a forward sensor and a backward sensor disposed on the base, and a detection protrusion disposed on the seat body and rotating with the seat body, wherein the forward sensor and the backward sensor are disposed opposite to each other; when the seat body is in the forward position, the detection protrusion triggers the forward sensor to output a forward position signal to the control module; when the seat body is in the backward position, the detection protrusion triggers the backward sensor to output a backward position signal to the control module.

[0020] In one embodiment, the seat posture adjustment component includes a drive motor, and the input component, when activated, can control the drive motor via a control module to adjust the tilt angle of the seat body.

[0022] A position detector, electrically connected to the control module, is used to detect the position of the slider relative to the drive shaft. The input component, when activated, controls the drive motor to adjust the tilt angle of the seat body.

[0023] In one embodiment, the anti-mistouch system has a standby state, an unlocked state, and a locked state. In the locked and standby states, the input component is disabled and therefore does not trigger the function. In the unlocked state, the input component is activated and therefore the function can be triggered. Specifically, when the anti-mistouch system is in the standby state, the control module responds to a first unlock operation to control the anti-mistouch system to enter the unlocked state to activate the input component. When the anti-mistouch system is in the locked state, the control module responds to a second unlock operation to control the anti-mistouch system to enter the unlocked state to activate the input component. The first unlock operation is manually adjusting the seat posture, and the second unlock operation is inputting a specific combination of input operations through the input component.

[0024] In one embodiment, when the anti-mistouch system is in the unlocked state, if the time during which the input component is inactive is longer than a first predetermined time, the anti-mistouch system switches to the locked state; when the anti-mistouch system is in the locked state, if the time during which the input component is inactive is longer than a second predetermined time, the anti-mistouch system switches to the standby state.

[0025] In one embodiment, the child safety seat's anti-accidental touch system further includes an ISOFIX detection mechanism, which includes a positioning sensor. When the positioning sensor detects that the ISOFIX connector has reached a preset insertion position within the ISOFIX socket, the positioning sensor outputs a positioning signal to the control module. When the anti-accidental touch system is in standby mode and the control module receives the positioning signal, the control module activates the input component, and the anti-accidental touch system switches to the unlocked state.

[0026] In one embodiment, the input component further includes a power interface electrically connected to the control module. When the anti-accidental touch system is in standby mode and an external power supply is plugged into the power interface, the control module activates the input component, and the anti-accidental touch system switches to the unlocked state.

[0027] In one embodiment, the anti-accidental activation system of the child safety seat further includes: a wireless receiving module disposed on the child safety seat and electrically connected to the control module; and a remote control wirelessly connected to the wireless receiving module. The input component includes the remote control.

[0028] In one embodiment, the control module responds to inaction by disabling the remote control within a preset time by performing a third unlock operation by activating the remote control. The third unlock operation is a combination of specific input operations performed via the remote control. Simple Explanation of the Diagram

[0059] In the description of this application, it should be understood that if the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc. appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0060] It should be noted that if a component is described as "fixed to" or "set on" another component, it can be directly on the other component or there may be an intervening component. If a component is described as "connected to" another component, it can be directly connected to the other component or there may be an intervening component.

[0061] Referring to Figures 1, 2, and 3, an embodiment of this application provides a child safety seat, including a base 100, a tilt angle adjustment mechanism 200, and a seat body 130. The seat body 130 is slidably connected to the base 100; the tilt angle adjustment mechanism 200 is pivotally connected to the base 100 and drivably connected to the seat body 130 to drive the seat body 130 to slide relative to the base 100, thereby adjusting the seat angle.

[0062] Specifically, as shown in Figure 3, the tilt angle adjustment mechanism 200 includes a transmission component 230, a driver 260, and a slider 220. The slider 220 is connected to the seat body 130 and is detachably engaged with the transmission component 230; the driver 260 is drivably connected to the transmission component 230 to drive the transmission component 230 to move the slider 220. The movement of the slider 220 drives the seat body 130 to slide relative to the base 100, thereby adjusting the seat angle.

[0063] In the child safety seat according to the embodiments of this application, by setting a slider 220 that is detachably engaged with the transmission member 230 and connected to the seat body 130, the driver 260 drives the transmission member 230 to move the slider 220. The movement of the slider 220 drives the seat body 130 to slide relative to the base 100, thereby adjusting the seat angle, which simplifies the structural complexity of the angle adjustment mechanism of the child safety seat. On the other hand, the engagement of the slider 220 with the transmission member 230 results in high transmission efficiency, simple connection method, low installation difficulty, and helps to improve assembly efficiency.

[0064] In one embodiment of this application, the tilt angle adjustment mechanism 200 further includes a bracket 210, which includes a connecting end 2102 pivotally connected to the base 100 and a free end 2103 extending into the seat body 130. Exemplarily, as shown in Figures 1 and 3, the connecting end 2102 of the bracket 210 is provided with a pivot portion 211, which has a pivot hole 2110. By passing a pivot shaft (not shown) through the pivot hole 2110 and a matching insertion hole (not shown) on the base 100, the bracket 210 can pivot around the pivot shaft.

[0065] In the embodiment shown in Figure 3, the seat body 130 includes a push rod 132 fixed to the seat body 130, which passes through a slider 220. The push rod 132 moves with the slider 220 to drive the seat body 130 to slide relative to the base 100. When the seat body 130 slides relative to the base 100, the bracket 210 also adaptively rotates about a pivot shaft passing through a pivot hole 2110.

[0066] Referring to Figures 1 and 2, the base 100 is provided with sliding rods 110, which are fixed to the base 100. In this embodiment, there are two sliding rods 110, which are arranged parallel to each other. Two sets of second sliding grooves 131 are formed on the seat body 130, each set including two opposing second sliding grooves 131. When the seat body 130 is installed on the base 100, each sliding rod 110 passes through one set of second sliding grooves 131 and can slide along the extending direction of the second sliding groove 131, thereby guiding the seat body 130 to slide relative to the base 100.

[0067] In this embodiment, the transmission component 230 is a screw 231. The outer surface of the screw 231 is provided with threads.

[0068] The tilt angle adjustment mechanism 200 includes a driver 260, which is fixedly connected to the bracket 210. In this embodiment, the driver 260 is located beside the pivot 211. The driver 260 includes a motor and a transmission mechanism (not shown) such as a gear. The axial direction of the motor shaft (not shown) is set at an angle to the axial direction of the screw 231. The transmission mechanism allows the rotation of the motor to drive the screw 231 to rotate. In some other embodiments, the transmission component 230 may also be a gear, rack, or chain, etc.

[0069] Referring to Figures 4A, 4B, 5A, and 5B, the slider 220 includes a engaging member 240 with a threaded portion 241, and a driving block 270 connected to the engaging member 240 to drive its movement. The engaging member 240 has a first position and a second position. As shown in Figure 4A, the engaging member 240 is in the first position, and the threaded portion 241 of the engaging member 240 engages with the thread on the outer surface of the screw 231. Understandably, when the screw 231 rotates, it can drive the slider 220 to move along the axis of the screw 231, thereby changing the position of the slider 220. As shown in Figure 4B, the engaging member 240 is in the second position, and the threaded portion 241 of the engaging member 240 disengages from the thread on the outer surface of the screw 231. Understandably, the rotation of the screw 231 can no longer drive the slider 220 to move. Referring to Figures 5A and 5B, the engaging member 240 includes a threaded portion 241 and a body 242 that are interconnected. Optionally, the threaded portion 241 and the body 242 are integrally formed.

[0070] Referring to Figures 4A, 4B, 6, and 7, the slider 220 is provided with a first channel 222 and a second channel 223. The screw 231 passes through the first channel 222, and the engaging member 240 is disposed in the second channel 223 and can reciprocate within the second channel 223. Taking the slider 220 shown in Figures 4A and 7 as an example, the first channel 222 is closer to the bottom of the slider 220 and extends horizontally through the slider 220 along the horizontal direction H. The second channel 223 is disposed in the middle of the slider 220 along the vertical direction V, and the bottom end of the second channel 223 communicates with the first channel 222, so that the engaging member 240 can engage with the screw 231 in the first channel 222. Setting the first channel 222 and the second channel 223 to be perpendicular to each other provides a better engagement effect between the engaging member 240 and the screw 231. In some embodiments, the engaging member 240 engages with the screw 231 from one side, that is, the threaded portion 241 only engages with a portion of the circumferential surface of the screw 231. Since both the screw 231 and the slider 220 are fixed on the bracket 210, and the screw 231 is confined in the first channel 222 and the engaging member 240 is confined in the second channel 223, the threaded portion 241 can provide appropriate engagement force by engaging only a portion of the circumferential surface of the screw 231, thereby simplifying the structure.

[0071] In other embodiments, the extending direction of the second channel 223 and the extending direction of the first channel 222 may not be perpendicular, but rather form an angle, which may be acute or obtuse. This allows the two opposite sides of the slider 220 to be of unequal length, thereby reducing the volume of the slider 220 and making its structure more compact, which is beneficial for use in a smaller space.

[0072] Referring again to Figures 4A, 4B, 6, and 7, the slider 220 also has a third channel 224. The drive block 270 is formed into a roughly rectangular parallelepiped structure and is disposed in the third channel 224, allowing it to slide along the third channel 224. Taking the slider 220 shown in Figure 7 as an example, the third channel 224 is located closer to the top of the slider 220 and extends horizontally through the slider 220 in the direction H. The middle part of the third channel 224 intersects and communicates with the second channel 223, so that the drive block 270 is simultaneously located within both the second channel 223 and the third channel 224.

[0073] The drive block 270 can reciprocate along the extension direction of the third channel 224 within the third channel 224, and can move to the third position shown in Figure 4A, that is, the drive block 270 moves to the right side along the third channel 224; the drive block 270 can also move to the fourth position shown in Figure 4B, that is, the drive block 270 moves to the left side along the third channel 224. Here, the directional terms "left side" and "right side" are used with reference to the positions shown in Figures 4A and 4B.

[0074] The drive block 270 is provided with a drive groove 2701, and a drive rod 2401 is fixedly provided on the engaging member 240. The drive rod 2401 is inserted into the drive groove 2701, and the extension direction of the drive rod 2401 is not parallel to the extension direction of the first channel 222. Specifically, referring to Figures 4A, 4B, 5A and 5B, in the direction away from the pivot 211 along the third channel 224, the drive groove 2701 is inclined in the direction away from the first channel 222.

[0075] Referring to Figures 4A and 7, when the drive block 270 moves toward the third position within the third channel 224, the drive groove 2701 also moves toward the third position. During this process, driven by the inner wall of the drive groove 2701, the drive rod 2401 gradually approaches the first channel 222, meaning the drive rod 2401 and the engaging member 240 gradually move toward the first position. When the drive block 270 reaches the third position, the engaging member 240 reaches the first position, thereby engaging with the screw 231. At this time, the seat angle can be adjusted by the drive of the actuator 260, and the child safety seat angle adjustment mechanism is in automatic adjustment mode. Similarly, referring to Figures 4B and 7, when the drive block 270 moves toward the fourth position within the third channel 224, the drive groove 2701 also moves toward the fourth position. During this process, driven by the inner wall of the drive groove 2701, the drive rod 2401 gradually moves away from the first channel 222, that is, the drive rod 2401 and the engaging member 240 gradually move towards the second position. When the drive block 270 reaches the fourth position, the engaging member 240 reaches the second position, thereby disengaging the engaging member 240 from the screw 231. At this time, the seat angle adjustment cannot be achieved by the drive of the driver 260, but can be achieved by the user's manual adjustment, and the child safety seat angle adjustment mechanism is in manual adjustment mode. Thus, the child safety seat angle adjustment mechanism described in this application can be driven by the drive block 270 to engage or disengage the engaging member 240 from the screw 231, so that the child safety seat angle adjustment mechanism can switch between automatic adjustment mode and manual adjustment mode.

[0076] The drive block 270 is also provided with a positioning groove 2702, which communicates with the drive groove 2701. The positioning groove 2702 is used to limit the relative movement of the drive rod 2401 within the drive groove 2701, so that the position of the drive rod 2401 within the drive groove 2701 is relatively fixed. Referring to Figures 5A and 5B, the positioning groove 2702 is connected to one end of the drive groove 2701 near the first channel 222. In this embodiment, the extending direction of the positioning groove 2702 is parallel to the extending direction of the first channel 222. Referring to Figures 4A, 5A, and 5B, when the drive block 270 is in the third position, the drive rod 2401 is located within the positioning groove 2702. Since the extension direction of the positioning groove 2702 is set at an angle to the extension direction of the drive groove 2701, the drive rod 2401 can remain relatively stably in the third position, reducing the probability that the drive block 270 will accidentally leave the third position in the event of shaking, inversion or collision, which helps the engaging member 240 and the screw 231 to maintain the engagement state and maintain the seat angle.

[0077] The tilt angle adjustment mechanism 200 also includes a reset member 250. Referring to Figures 4A and 4B, the slider 220 is also provided with a stop 226, which is fixedly disposed on the left side of the slider 220, with a portion of the stop 226 located in the extension direction of the third channel 224. The reset member 250 is disposed between the stop 226 and the drive block 270, with one end of the reset member 250 abutting against the drive block 270 and the other end abutting against the stop 226. The reset member 250 continuously applies a pushing force to the drive block 270 in a direction away from the stop 226, so that the drive block 270 always has a tendency to move towards the third position. By providing the reset member 250, the drive block 270 moves towards the third position, which helps the engaging member 240 and the screw 231 to maintain a stable engagement state; on the other hand, providing the reset member 250 can also allow the engaging member 240 and the screw 231 to automatically return to the engagement state after disengagement.

[0078] In this embodiment, the reset member 250 is a compression spring, which is low in cost and can stably apply a pushing force to the drive block 270. The compression spring is always kept in a compressed state between the stop portion 226 and the drive block 270 to continuously apply a pushing force to the drive block 270. Alternatively, the reset member 250 can also be selected from other suitable structures, such as a spring sheet, torsion spring, etc., as long as it can stably apply a pushing force to the drive block 270.

[0079] In some other embodiments, the two ends of the reset member 250 can also be fixedly connected to the drive block 270 and the stop portion 226 respectively. This can reduce the probability of the reset member 250 losing contact with the drive block 270 and the stop portion 226, and can more stably and continuously apply thrust to the drive block 270.

[0080] In this embodiment, the stop portion 226 is fixedly connected to the slider 220 by screws. In other embodiments, the stop portion 226 can also be connected to the slider 220 by means of bonding, welding, or other methods. The stop portion 226 can also be integrally formed with the slider 220, thus providing a better fixing effect of the stop portion 226 on the slider 220.

[0081] The tilt angle adjustment mechanism 200 also includes a connector 290 and an operating member 280 to facilitate the remote driving of the drive block 270 within the third channel 224.

[0082] Referring to Figures 2, 4A, and 4B, specifically, the operating element 280 is disposed on the seat body 130, one end of the connecting element 290 is connected to the operating element 280, and the other end of the connecting element 290 is connected to the drive block 270. Exemplarily, the connecting element 290 is a steel wire. The operating element 280 pulls the steel wire, which in turn pulls the drive block 270 to overcome the thrust of the reset element 250 and move the drive block 270 to the fourth position. This disengages the engaging element 240 from the screw 231, allowing the slider 220 to move freely along the axis of the screw 231. At this time, the angle adjustment mechanism of the child safety seat is in manual adjustment mode, and the user can manually adjust the angle of the seat body 130.

[0083] Referring to Figure 3, the stop portion 226 is provided with a through groove 2261. The through groove 2261 is aligned with the reset member 250 in the extension direction along the third channel 224, and the through groove 2261 allows the connector 290 to pass through. In this embodiment, during installation, the steel wire is first passed through the through groove 2261 and then through the spring along the axis of the spring before being connected to the drive block 270. The through groove 2261 can limit the position of the connector 290, prevent the connector 290 from swinging, and improve the sensitivity of switching to manual adjustment mode.

[0084] Referring again to Figure 3, the bracket 210 includes two opposing limiting brackets 212, which are spaced apart to form a first sliding groove 2101. At least a portion of the slider 220 is located within the first sliding groove 2101, allowing the slider 220 to move along the extending direction of the first sliding groove 2101 under the limiting action of the two limiting brackets 212. The screw 231 is parallel to the extending direction of the first sliding groove 2101 to smoothly drive the slider 220 to move along the first sliding groove 2101, reducing the probability of jamming.

[0085] The slider 220 is also provided with a connecting portion 227, through which the push rod 132 passes. In this embodiment, referring to Figures 1, 3, and 6, the connecting portion 227 protrudes from the surface of the slider 220, providing better support for the push rod 132. The connecting portion 227 is provided with a connecting hole 2271, the extension direction of which is parallel to the extension direction of the sliding rod 110. The push rod 132 passes through the connecting hole 2271, and under the limiting effect of the annular inner wall corresponding to the connecting hole 2271, it maintains a nearly parallel state with the sliding rod 110, reducing the probability of jamming when adjusting the seat angle.

[0086] Further, the connecting portion 227 is provided with a detection protrusion 2273. Referring to Figures 1, 3, and 6, the bracket 210 is also provided with a limiting clamp 213. In this embodiment, the limiting clamp 213 is disposed near the limiting frame 212 of the driver 260 and is located on the side of the limiting frame 212 opposite to the screw 231. Optionally, a position detector 2130 is also provided, which may include a first position detector 2131 and a second position detector 2132. The first position detector 2131 is disposed on the side of the limiting clamp 213 near the connecting end 2102, and the second position detector 2132 is disposed on the side of the limiting clamp 213 near the free end 2103. Optionally, the position detector 2130 may also include a third position detector 2133. The third position detector 2133 is disposed between two opposite ends of the limiting clamp 213 and is located between the first position detector 2131 and the second position detector 2132. The detection protrusion 2273 extends in a direction away from the third channel 224 along a direction parallel to the extension direction of the second channel 223, so as to abut against the first position detector 2131, the second position detector 2132, or the third position detector 2133 when the slider 220 moves along the length direction of the screw 231. By setting the position detector 2130, the travel of the slider 220 in the extension direction of the first sliding groove 2101 can be detected, so that the angle adjustment mechanism of the child safety seat can adjust the angle within a preset range.

[0087] Figures 10 to 16 illustrate a child safety seat angle adjustment mechanism according to another embodiment of this application. The following description focuses solely on the differences between the child safety seat angle adjustment mechanism according to this embodiment and the child safety seat angle adjustment mechanism in the foregoing embodiments.

[0088] Referring to Figure 11, in this embodiment, the base 100 is provided with a power interface 101 for connecting an external power source to power the components of the child safety seat. For example, the external power source powers the motor in the driver 260 via the power interface 101. Optionally, the power interface 101 can be any electrical interface known in the art, such as a DC interface, a USB interface, a Lightning interface, etc. In the embodiment shown in Figure 11, the power interface 101 is a USB Type-C interface. In addition, in this embodiment, the power interface 101 is located at the bottom of the base 100 near the support feet, which can prevent the child sitting in the child safety seat from kicking the power cord, and also prevent the power cord from interfering with the vehicle seat when the child safety seat is installed on the vehicle seat.

[0089] Referring to Figure 12, in this embodiment, the bracket 210 of the tilt angle adjustment mechanism 200 includes a connecting end 2102 pivotally connected to the base 100 and a free end 2103 opposite to the connecting end 2102. That is, the bracket 210 is arranged in the base 100 in a generally "lying down" position. When adjusting the seat angle, the actuator 260 drives the screw 231 to pivot. The pivoting of the screw 231 causes the slider 220 to move along the axis of the screw 231. Thus, the slider 220 drives the seat body 130 to slide relative to the base 100 via the push rod 132 (refer to Figure 13) provided on the seat body 130.

[0090] Referring to Figures 14 and 15, when the seat body 130 slides relative to the base 100, the seat body 130 moves in a roughly circular arc trajectory. In the plane containing this arc, the angle formed by the intersection of the virtual line L1 connecting the center O of the arc and the push rod 132 with the direction L2 of the driving force F exerted by the slider 220 on the push rod 132, pointing towards the front of the seat body 130, is defined as the action angle α. In this application, the front of the seat body 130 refers to the part of the seat body 130 away from the backrest; correspondingly, the rear of the seat body 130 refers to the part where the backrest is located. As shown in Figure 14, the seat body 130 is in a reclining state. At this time, the connecting end 2102 and the free end 2103 of the support 210 are approximately at the same height in the vertical direction V, thus the support 210 is in a roughly "flat" posture. At this time, the action angle α is at its maximum value. Optionally, the maximum value of the action angle α is 94°. During the transition of the seat body 130 from the reclining state shown in Figure 14 to the upright state shown in Figure 15, as the seat body 130 slides relative to the base 100, the support 210 pivots, and the free end 2103 of the support 210 gradually rises in the vertical direction V, while the angle of action α gradually decreases. When the seat body 130 reaches the upright state shown in Figure 15, the height of the free end 2103 of the support 210 is greater than the height of the connecting end 2102 in the vertical direction V, thus the support 210 is in a roughly "reclined" posture. At this time, the angle of action α is at its minimum value. Optionally, the minimum value of the angle of action α is 78°. Those skilled in the art will understand that the component of the driving force F perpendicular to the virtual connection line L1 can drive the seat body 130 to slide; therefore, the closer the angle of action α is to 90°, the larger this component force is, and the higher the efficiency of the driving force F. When the angle of action α equals 90°, the driving force F is fully used to drive the seat body 130 to slide. At this time, the minimum driving force F can be used to drive the seat body 130 to slide, and the driving force F has the highest efficiency. In this embodiment, when the seat body 130 switches between the reclining state and the upright state, the angle of action α is always close to 90°, for example, the angle of action α is in the range of 78° to 98°. Therefore, the driving force F always has a high efficiency, making the sliding of the seat body 130 smoother and the load on the actuator 260 smaller. This helps to extend the service life of the angle adjustment mechanism of the child safety seat and reduce the failure rate.

[0091] Referring again to Figure 12, in this embodiment, a pivot shaft 2104 passes through the connecting end 2102 of the bracket 210. The base 100 is provided with mounting ribs 1201 and mounting seats 1202. A through hole 12011 is formed on the mounting ribs 1201. The end of the pivot shaft 2104 passes through the through hole 12011, and the pivot shaft 2104 is fixed to the mounting seat 1202. Specifically, the base 100 is provided with two sets of mounting ribs 1201, each set containing two mounting ribs 1201. Each sliding rod 110 passes through one set of mounting ribs 1201 to be fixed to the base 100. Optionally, the mounting ribs 1201 are formed of metal sheet, for example, iron sheet. One of the mounting ribs 1201 has a through hole 12011, through which the first end of the pivot shaft 2104 passes. The second end of the pivot shaft 2104, opposite to the first end, is fixedly connected to the mounting base 1202, thereby pivotally connecting the connecting end 2102 to the base 100. Optionally, the base 100 is provided with two mounting bases 1202. The first end of the pivot shaft 2104 passes through the through hole 12011 and is accommodated or fixed in one of the mounting bases 1202, while the second end of the pivot shaft 2104 is fixedly connected to the other mounting base 1202.

[0092] Referring to Figures 12 and 16, a mounting groove 1203 is provided on the mounting base 1202, and the end of the pivot shaft 2104 is accommodated in the mounting groove 1203. Specifically, in the embodiment shown in Figure 16, the first end of the pivot shaft 2104 passes through the through hole 12011 and is accommodated in the mounting groove 1203 of one of the mounting bases 1202, a portion of the second end of the pivot shaft 2104 is accommodated in the mounting groove 1203 of the other mounting base 1202, and the other portion of the second end of the pivot shaft 2104 is fixed to the other mounting base 1202 by a fastener 400. Optionally, the fastener 400 can be any fixing device such as a screw, rivet, or fixing pin. Optionally, a portion of the first end of the pivot shaft 2104 passing through the through hole 12011 is accommodated in the mounting groove 1203 of the mounting base 1202, and the other portion of the first end of the pivot shaft 2104 passing through the through hole 12011 is fixed to the mounting base 1202. Alternatively, the end of the pivot shaft 2104 may not be fixed to the mounting base 1202 by means of fastener 400. The end of the pivot shaft 2104 may be fixed to the mounting base 1202 by means of magnetic connection, bonding, welding or other methods.

[0093] Referring again to Figure 16, in this embodiment, a shock-absorbing sleeve 2105 is fitted onto the end of the pivot shaft 2104, and the shock-absorbing sleeve 2105 is located between the end of the pivot shaft 2104 and the mounting groove 1203. Specifically, the shock-absorbing sleeve 2105 is fitted onto the portions of the first and second ends of the pivot shaft 2104 that are accommodated in the mounting groove 1203 to buffer the vibrations caused by the driver 260 (e.g., a motor) and transmitted to the mounting rib 1201 via the bracket 210 and the pivot shaft 2104, thereby reducing or avoiding noise and mechanical wear caused by vibration, optimizing the passenger's riding experience, and extending the service life of the angle adjustment mechanism of the child safety seat. Optionally, the shock-absorbing sleeve 2105 is made of silicone material, for example. In some embodiments, the base 100 also includes a rotating seat 120. Referring to Figures 8 to 11, the rotating seat 120 is rotatably disposed on the base 100, and the tilt angle adjustment mechanism 200 is pivotally connected to the rotating seat 120. In this way, the child safety seat can not only adjust the angle, but also the direction the passenger is facing, improving ease of use.

[0094] Referring to Figures 17, 18, 27, and 28, an embodiment of this application provides a child safety seat 1, including a seat body 130, a base 100, and a seat posture adjustment assembly 20 disposed in at least one of the seat body 130 or the base 100. The seat posture adjustment assembly 20 is used to adjust the position of the seat body 130 relative to the base 100. Exemplarily, the seat posture adjustment assembly 20 includes at least one of a rotation position adjustment mechanism for adjusting the rotational position of the seat body 130 and a tilt angle adjustment mechanism 200 for adjusting the tilt angle of the seat body 130. As shown in Figure 27, the rotation position adjustment mechanism includes a rotating disk 72 connected to the seat body 130, the seat body 130 being connected to the rotating disk 72, and the rotating disk 72 being pivotally connected to the base 100. Thus, the seat body 130 is pivotally connected to the base 100 via the rotating disk 72, and the seat body 130 can rotate freely relative to the base 100. Additionally, the rotating disk 72 is provided with a retractable locking pin 513, and the base 100 is provided with multiple locking holes 510 that engage with the locking pin 513. When the locking pin 513 is inserted into the locking hole 510, the seat body 130 can be locked in a forward position (as shown in Figure 17) and a rearward position (as shown in Figure 18) relative to the base 100. Referring also to Figures 27 and 28, optionally, the seat posture adjustment assembly 20 includes a tilt angle adjustment mechanism 200 to allow the seat body 130 to slide relative to the base 100 in the W1 and W2 directions shown in Figure 17, thereby adjusting the tilt angle of the backrest of the seat body 130 and switching between upright and reclining modes.

[0095] Referring to Figures 17 and 19, in this embodiment, an input component 30 is optionally provided at the front end of the base 100. Alternatively, the input component 30 can also be provided at other suitable locations on the child safety seat 1, such as on the seat body 130. Alternatively, the input component can be any other suitable mechanism, as long as it can input control commands. Figure 19 shows a schematic structure of the input component 30 in Figure 17. In the embodiment shown in Figure 19, the input component 30 includes multiple buttons 31 and a display 32. Alternatively, the input component 30 can also include only one of the buttons 31 or the display 32. Optionally, the display 32 can be a touch screen, and the user inputs control commands by touching virtual buttons displayed on the touch screen. Specifically, in this embodiment, the buttons 31 include a power button 311, a ventilation control button 312, and two seat tilt angle adjustment buttons 313. The power button 311 is used to control the input component 30 to enter an unlocked state or a standby state. The ventilation control button 312 is used to control the opening and closing of the fan of the seat ventilation device 71 (refer to Figure 27) and to adjust the fan speed. One seat tilt angle adjustment button 313 is used to increase the tilt angle of the backrest of the seat body 130; the other seat tilt angle adjustment button 313 is used to decrease the tilt angle of the backrest of the seat body 130. It should be noted that the power button 311, ventilation control button 312, and two seat tilt angle adjustment buttons 313 shown in Figure 19 are only exemplary. Those skilled in the art can set other suitable buttons on the input component 30 as needed, such as a display brightness adjustment button, a seat ventilation device power adjustment button, etc. Optionally, the button 31 can be a touch button or a mechanical button. The buttons 31 located on the base 100 or the seat body 130 are easily accidentally touched or operated by children sitting in the child safety seat 1, causing the ventilation and electric tilt angle adjustment functions of the child safety seat 1 to be accidentally activated, causing inconvenience to the user.

[0096] Referring also to Figures 19 and 20a, in one embodiment of this application, the display 32 includes a first display area 321 and a second display area 322, which can display different interfaces respectively. The interface content displayed by the display 32 will be described below with reference to Figures 20a to 22b.

[0097] Referring also to Figures 23a, 23b, 25a, and 25b, in one embodiment of this application, the anti-accidental activation system 50 of the child safety seat 1 includes a seat posture detection module 51 and a control module 52. The seat posture detection module 51 is disposed on the seat body 130 or the base 100 to detect the seat posture of the seat body 130. In embodiments of this application, the term "seat posture" includes at least one of the rotational position of the seat body 130 and the tilt angle of the backrest of the seat body 130. The control module 52 is electrically connected to the input component 30 and the seat posture detection module 51. The control module 52 can disable the input component 30 in response to the seat posture not changing within a preset time. For example, when powered only by the built-in battery and the seat posture does not change within 5 minutes, the control module 52 will disable the input component 30, preventing the function from being triggered by the input component 30, thus avoiding accidental activation of the seat function due to accidental touch. For example, when the seat posture changes, the control module 52 will activate the input component 30, which can then trigger the corresponding function. It will be understood by those skilled in the art that a child sitting in the seat body 130 cannot change the seat posture independently, thus effectively preventing accidental operation of the input component 30 by the child.

[0098] In one embodiment of this application, the child safety seat 1 has a standby state, an unlocked state, and a locked state. In the unlocked state, the standby state can be entered by pressing and holding, for example, the power button 311. In the standby state, the child safety seat 1 is powered by the built-in battery, cutting off power to high-power components such as the display 32, the fan of the ventilation device 71, and the driver 260 of the tilt angle adjustment mechanism 200. At the same time, the microcontroller of the control module 52 enters a low-power mode to save power consumption. Optionally, the driver 260 may include a motor and a transmission mechanism such as gears (not shown). At this time, the user cannot turn on the fan or adjust the backrest tilt angle by pressing button 31. The control module 52 only responds to power-on input signals (i.e., the first unlocking operation) from the power button 311, the external power interface (e.g., power interface 101, refer to FIG. 27), the seat posture detection module 51's positioning sensor 531 and position detector 2130, etc. The power-on input signal can be generated in one or more of the following ways: (1) pressing and holding the power button 311; (2) connecting an external power source; (3) the positioning sensor 531 detects that the ISOFIX connector on either the left or right side has reached the preset insertion position in the ISOFIX socket; (4) the forward sensor 511 detects that the seat body 130 is in a forward position or the rearward sensor 512 detects that the seat body 130 is in a rearward position; (5) the angle sensor detects that the tilt angle of the backrest of the seat body 130 relative to the base 100 has changed. When the power-on input signal is received in the standby state, the child safety seat 1 switches from the standby state to the unlocked state and supplies power to the display 32 and other components. In the unlocked state, the user can turn on the fan or adjust the tilt angle of the backrest by pressing the button 31 through the input component 30. In the locked state, the control module 52 does not respond to any input signal other than the unlock signal to avoid accidental triggering of seat functions due to accidental touch. At this time, the running functions such as the fan will not be turned off due to power interruption.

[0099] Specifically, in the locked and standby states, the input component 30 is disabled and therefore does not trigger the function; in the unlocked state, the input component 30 is activated and therefore the function can be triggered. When the anti-mistouch system 50 is in standby state, the control module 52 responds to the first unlock operation by controlling the anti-mistouch system 50 to enter the unlocked state to activate the input component 30. When the anti-mistouch system 50 is in the locked state, the control module 52 responds to the second unlock operation by controlling the anti-mistouch system 50 to enter the unlocked state to activate the input component 30. Optionally, the first unlock operation is manually adjusting the seat posture, and the second unlock operation is inputting a specific combination of input operations through the input component 30. "Inputting a specific combination of input operations through the input component 30" is, for example, pressing two different buttons 31 within a third preset time. Optionally, the third preset time can be 0.5S, 1S, etc. Those skilled in the art will understand that 0.5S and 1S are merely exemplary, and those skilled in the art can select an appropriate duration for the third preset time according to actual needs. In this embodiment, two different buttons 31 need to be pressed within, for example, 0.5 seconds, to unlock the anti-mistouch system 50, thereby preventing accidental activation of the input component 30 due to accidental button presses. Optionally, in one embodiment of this application, when the anti-mistouch system 50 is in the unlocked state, if the time of inactivity of the input component 30 exceeds a first predetermined time, the anti-mistouch system 50 switches to the locked state to disable the input component 30. Optionally, the first predetermined time can be 5 seconds, 10 seconds, etc. Those skilled in the art will understand that 5 seconds and 10 seconds are merely examples, and they can choose an appropriate duration for the first predetermined time according to actual needs. Optionally, in one embodiment of this application, when the anti-mistouch system 50 is in the locked state, if the time of inactivity of the input component 30 exceeds a second predetermined time, the anti-mistouch system 50 switches to the standby state to disable the input component 30. Optionally, the second predetermined time can be 5 minutes, 10 minutes, etc. Those skilled in the art will understand that 5 minutes and 10 minutes are merely examples, and they can choose an appropriate duration for the second predetermined time according to actual needs.

[0100] In one embodiment of this application, the anti-accidental touch system 50 further includes an ISOFIX detection mechanism 53 for detecting whether the ISOFIX connector has reached a preset insertion position within the ISOFIX socket. The ISOFIX detection mechanism 53 includes a positioning sensor 531. When the positioning sensor 531 detects that the ISOFIX connector 532 has reached the preset insertion position within the ISOFIX socket, the positioning sensor 531 outputs a positioning signal to the control module 52. When the anti-accidental touch system 50 is in standby mode and the control module 52 receives the positioning signal, the control module 52 switches the anti-accidental touch system 50 to the unlocked state to activate the input component 30. Specifically, referring to FIG18, ISOFIX detection mechanisms 53 are respectively provided on the left and right ISOFIX connectors 532. For the sake of simplicity, the ISOFIX connector 532 located on the left side is used as an example for explanation. When the positioning sensor 531 detects that the ISOFIX connector 532 on the left side of the base 100 has reached the preset insertion position in the ISOFIX socket (not shown) on the left side of the rear seat of the vehicle, the positioning sensor 531 outputs a positioning signal to the control module 52. If the anti-accidental touch system 50 is in standby mode at this time, the control module 52 activates the input component 30, and the anti-accidental touch system 50 switches to the unlocked state. Thus, when the user installs the child safety seat 1 into the rear seat of the vehicle via the ISOFIX connector 532, as long as either the left or right ISOFIX connector is inserted, the anti-accidental touch system 50 can switch from standby mode to unlocked mode to activate the input component 30, eliminating the need for manual state switching and improving ease of use. Optionally, the control module 52 can also be configured to only switch the anti-accidental touch system 50 to unlocked mode to activate the input component 30 when both ISOFIX connectors 532 are inserted. Optionally, the display 32 can show the insertion status of the ISOFIX connector 532. For example, as shown in FIG21d, when both ISOFIX connectors 532 on both sides are not inserted, the α, β, and γ areas are displayed in red; when only the right ISOFIX connector 532 is inserted, the α and γ areas are displayed in red, and the β area is displayed in green; when only the left ISOFIX connector 532 is inserted, the β and γ areas are displayed in red, and the α area is displayed in green; when both ISOFIX connectors 532 on both sides are inserted, the α, β, and γ areas are all displayed in green. Optionally, in this embodiment, the positioning sensor 531 is a limit switch, and a second drive member 533 is respectively provided on the left and right sides of the base 100. When the hook of the ISOFIX connector 532 pivots and engages with the lever in the ISOFIX interface at the vehicle seat, the second drive member 533 cooperating with the hook moves with the pivot of the hook and abuts against the limit switch, triggering the limit switch. The limit switch outputs a positioning signal to the control module 52.

[0101] In one embodiment of this application, the base 100 is further provided with a battery (not shown) for powering the input component 30 and the anti-mistouch system 50. Optionally, when the anti-mistouch system 50 is locked or unlocked, and the battery level is lower than a preset value, the display 32 displays low battery information, for example, as shown in FIG22a. Optionally, the input component 30 is provided with a power interface 101 (refer to FIG27), which is electrically connected to the control module 52 for connecting an external power source. The external power source is used to power, for example, the ventilation device 71 and the seat posture adjustment component 20. In embodiments where the battery is a rechargeable battery, the external power source can also be used to charge the battery. In such embodiments, compared with the case where an external power source is connected, the second predetermined time will be shorter when no external power source is connected. For example, the second predetermined time can be 1 minute, 3 minutes, etc., so as to enter the standby state more quickly and save battery power.

[0102] Referring to Figures 24 and 25b, in one embodiment of this application, the child safety seat 1 further includes a wireless receiving module and a remote control 60. The wireless receiving module is, for example, mounted on the child safety seat 1 and electrically connected to the control module 52. The remote control 60 is wirelessly connected to the wireless receiving module. In such an embodiment, the input component 30 includes the remote control 60. Optionally, the remote control 60 is provided with multiple remote control buttons. In this embodiment, the remote control buttons include a ventilation button 611, a ventilation off button 612, a seat upright button 613, a seat recline button 614, and two seat tilt angle adjustment buttons 615. Specifically, pressing the ventilation off button 612 turns off the seat ventilation device 71. Pressing the ventilation button 611 turns on the seat ventilation device 71. Pressing the ventilation button 611 again allows the seat ventilation device 71 to sequentially switch between three ventilation intensity modes: high-speed ventilation, medium-speed ventilation, and low-speed ventilation. Pressing the seat upright button 613 gradually reduces the tilt angle of the seat body 130 until the seat body 130 reaches an upright position. Pressing the reclining button 614 gradually increases the tilt angle of the seat body 130, bringing it into reclined mode. The two reclining angle adjustment buttons 615 control the seat body 130 to rotate in the direction of increasing and decreasing tilt angle, respectively; pressing a reclining angle adjustment button 615 changes the seat angle by one level.

[0103] Optionally, the remote control 60 may also have a pairing function, through which the remote control 60 can be paired with the wireless receiving module. In one embodiment, the pairing method is as follows: when the input component 30 is in the start state, first press the pairing button 33 on the input component 30, and then press any remote control button within a set time, such as 8 seconds, 10 seconds, etc., to complete the pairing.

[0104] In another embodiment, optionally, the control module 52 is configured to disable the remote control 60 in response to no operation within a preset time; the control module 52 also activates the remote control 60 in response to a second unlocking operation. The second unlocking operation includes inputting a specific combination of input operations via the remote control 60. "Inputting a specific combination of input operations via the remote control 60" is, for example, pressing two different remote control buttons within a fourth preset time. Optionally, the fourth preset time can be 0.5 seconds, 1 second, etc. Those skilled in the art will understand that 0.5 seconds and 1 second are merely exemplary, and they can choose an appropriate duration for the fourth preset time according to actual needs. This approach avoids accidental execution of corresponding functions due to accidental touches of remote control buttons, thus preventing inconvenience to the user.

[0105] In one embodiment of this application, the child safety seat 1 is further provided with a prompter. The prompter is, for example, disposed within the seat body 130 or the base 100 and electrically connected to the control module 52. Optionally, the prompter is a buzzer capable of emitting an audible prompt signal. The buzzer emits a beeping sound when certain specific events occur. For example, the buzzer emits a beeping sound when the remote control 60 successfully pairs; or when the anti-accidental touch system 50 enters or exits standby mode, the buzzer emits a beeping sound with a relatively long duration (greater than 1 second, e.g., 2 seconds, 5 seconds, etc.).

[0106] Referring to Figure 25b, in one embodiment of this application, the control module 52 includes: a first control board; a second control board; and a third control board (not shown). The first control board is disposed in the base 100, and the second control board is disposed in the seat body 130. The first and second control boards are electrically connected via, for example, an electric slip ring (not shown). In this embodiment, the seat posture detection module 51 includes a tilt angle detection mechanism, an orientation detection mechanism, and an ISOFIX detection mechanism. The tilt angle detection mechanism is used to detect the tilt angle of the seat body 130, and the tilt angle detection mechanism is electrically connected to the second control board. In other embodiments, optionally, the tilt angle detection mechanism includes an angle sensor, which is electrically connected to the control module 52. Optionally, the angle sensor is a Hall sensor; when the Hall sensor detects a change in the tilt angle of the seat body 130, the angle sensor outputs a tilt angle change signal to the control module 52. If the anti-accidental touch system 50 is in standby mode at this time, the control module 52 activates the input component 30, and the anti-accidental touch system 50 switches to the unlocked state. For example, when a child manually adjusts the tilt angle of the seat body 130 before sitting on it for safety and comfort, the input component 30 automatically activates, and the anti-accidental touch system 50 switches to the unlocked state, thereby improving ease of use. In other embodiments, the angle sensor can also be a gyroscope or other sensors capable of sensing angle changes. The orientation detection mechanism is used to detect the rotational position of the seat body 130 and is electrically connected to the first control board. The ISOFIX detection mechanism is, for example, the ISOFIX detection mechanism 53 in the aforementioned embodiment, which is electrically connected to the first control board. Optionally, a third control board is disposed in the input component 30 and electrically connected to the first control board.

[0107] Referring to Figures 26 and 27, in one embodiment of this application, the orientation detection mechanism includes a forward sensor 511, a backward sensor 512, and a detection protrusion 513. The forward sensor 511 and the backward sensor 512 are disposed opposite each other in the base 100, and the detection protrusion 513 is disposed on the rotating disk 72 of the seat body 130 and can rotate with the seat body 130. Optionally, a retractable locking pin 513 disposed on the rotating disk 72 can be used as the detection protrusion 513. Exemplarily, the forward sensor 511 and the backward sensor 512 are spring switches. When the seat body 130 is in the forward position, the detection protrusion 513 extends into the engagement hole 510 located at the rear of the base 100, presses against and triggers the forward sensor 511 to output a forward position signal to the control module 52; when the seat body 130 is in the rear position, the detection protrusion 513 extends into the engagement hole 510 located at the front of the base 100, presses against and triggers the rearward sensor 512 to output a rearward position signal to the control module 52. Specifically, when the anti-accidental touch system 50 is in standby mode, the user manually rotates the seat body 130 to change its rotational position. When the seat body 130 is rotated to and locked in the forward (or backward) position, the forward sensor 511 (or backward sensor 512) is triggered by the detection protrusion 513, inputting a forward position signal (or backward position signal) to the control module 52. The control module 52 then activates the input component 30 and restores power to components such as the display, fan, and drive motor, and the anti-accidental touch system 50 enters the unlocked state. This allows for quick unlocking, improving ease of use. Optionally, the display base 100 is currently in forward mode, as shown in Figure 21a. Specifically, when the anti-accidental touch system 50 is in standby mode, and the control module 52 receives a backward position signal, the control module 52 activates the input component 30, and the anti-accidental touch system 50 enters the unlocked state. Optionally, the display base 100 is currently in backward mode, as shown in Figure 21b.

[0108] In other embodiments, the orientation detection mechanism may also include a lateral sensor (not shown). When the seat body 130 is in a lateral position, the detection convex 513 triggers the lateral sensor to output a lateral position signal to the control module 52. When the anti-accidental touch system 50 is in standby mode, and the control module 52 receives the lateral position signal, the control module 52 activates the input component 30, and the anti-accidental touch system 50 enters an unlocked state. Optionally, the display shows that the base 100 is currently in lateral mode, as shown in Figure 21c.

[0109] Referring again to Figures 26 and 27, in this embodiment, the seat posture detection module 51 includes: a fixed base 516, a first drive member 517, a trigger spring 519, a forward sensor 511, and a backward sensor 512. The forward sensor 511 and the backward sensor 512 are the same sensor. Specifically, the forward sensor 511 and the backward sensor 512 are limit switches, which can be electrically connected to the control module 52 via, for example, wires or other electrical connectors. The fixed base 516 is fixedly mounted on the base 100, which is provided with a locking hole 510. The first drive member 517 is columnar and coaxially disposed within the locking hole 510. A trigger spring 519 is disposed around the periphery of the first drive member 517, and the forward sensor 511 is disposed beside the trigger spring 519 located around the periphery of the first drive member 517. A return spring 518 is also provided at the end of the first drive member 517, abutting against the base 100. The bottom side of the seat body 130 is provided with a detection protrusion 513, for example, in the form of a locking pin, and the periphery of the detection protrusion 513 is provided with a ring connection portion 514.

[0110] In other embodiments, the forward sensor 511 and the rearward sensor 512 can also be through-beam sensors. When the seat body 130 rotates into position, the detection protrusion 513 moves out to block the beam of the through-beam sensor, triggering the through-beam sensor. The through-beam sensor then outputs a position signal to the control module 52, so as to selectively activate the input component 30 according to the rotation position of the seat body 130, so that the anti-accidental touch system 50 enters the unlocked state. The forward sensor 511 and the rearward sensor 512 can also be other types of sensors, which are not listed here.

[0111] Referring to Figures 27 and 28, in one embodiment of this application, the seat posture adjustment assembly 20 further includes a tilt angle adjustment mechanism 200. The tilt angle adjustment mechanism 200 includes: a transmission member 230, a slider 220, a driver 260, an operating member 280, and a position detector 2130. Optionally, the position detector 2130 may include: a first position detector 2131; a second position detector 2132; and a third position detector 2133. A push rod 132 passes through one end of the slider 220, and the slider 220 is drivably connected to the seat body 130 via the push rod 132. The other end of the slider 220 is detachably engaged with the transmission member 230. The transmission member 230 is, for example, a screw. One end of the slider 220 is pivotally connected to the push rod 132 at the seat body 130, and the other end of the slider 220 is sleeved on the screw. The inner surface of the slider 220 is threaded, allowing it to move along the transmission member 230. The movement of slider 220 along transmission member 230 can drive seat body 130 to slide relative to base 100, thereby changing the tilt angle of seat body 130. Driver 260 is drivably connected to transmission member 230 to drive transmission member 230 to move slider 220. Operating member 280 is disposed on seat body 130 and is used to disengage slider 220 from transmission member 230, thereby enabling manual adjustment of the tilt angle of seat body 130. Specifically, slider 220 is connected to operating member 280 via, for example, a steel wire. When the user pulls operating member 280, operating member 280 drives slider 220 away from transmission member 230 via the steel wire, disengaging it from transmission member 230. This releases the drivable connection between seat body 130 and driver 260, allowing the user to manually change the tilt angle of seat body 130. Multiple position detectors 2130 are arranged along the extension direction of the transmission member 230 and electrically connected to the control module 52 for detecting the position of the slider 220 relative to the transmission member 230. For example, the position sensor 405 is a photoelectric sensor. In this embodiment, when the anti-accidental touch system 50 is in standby or locked state, the user cannot adjust the tilt angle of the seat body 130 via the input component 30. At this time, the user can manually adjust the tilt angle of the seat body 130 via the operating component 280. The position sensor 405 detects the movement of the slider 220 and outputs a seat posture signal to the control module 52 to activate the input component 30. When the input component 30 is activated, the user can quickly control the driver 260 to adjust the tilt angle of the seat body 130 via the function buttons of the input component 30, thereby improving ease of use.

[0112] In the embodiment shown in Figure 27, the seat body 130 is provided with a ventilation device 71, which is electrically connected to the control module 52. The ventilation device 71 can be started or stopped via a button 31 on the input component 30, such as the ventilation control button 312. Optionally, the ventilation control button 312 can also be used to adjust the power of the seat ventilation device 71, for example, by pressing and holding the ventilation control button 312 or pressing it twice to change the power of the seat ventilation device 71. In the embodiment with the ventilation device 71, when the ventilation control button 312 or the seat tilt angle adjustment button 313 is pressed without an external power supply, the display 32 will display the "Power Connection" icon as shown in Figure 22b, prompting the user that an external power supply is required to activate the seat ventilation function or the seat tilt angle adjustment function.

[0113] This application also provides a method for operating the child safety seat, referring to Figure 23b, the method comprising the following steps:

[0114] When the anti-accidental touch system 50 is in standby mode, operating the seat body 130 of the child safety seat 1 relative to the base 100 to a preset engagement position, such as a forward, rearward, or side position, unlocks the anti-accidental touch system 50. When the anti-accidental touch system 50 is in standby mode, operating the ISOFIX connectors to reach a preset insertion position within the ISOFIX socket, such as either side's ISOFIX connector reaching the preset insertion position or both sides' ISOFIX connectors reaching the preset insertion position within the ISOFIX socket, unlocks the anti-accidental touch system 50. When the anti-accidental touch system 50 is in standby mode, changing the tilt angle of the seat body 130's backrest unlocks the anti-accidental touch system 50. When the anti-accidental touch system 50 is in standby mode, pressing the power button 311 on the input component 30 unlocks the anti-accidental touch system 50. When the anti-accidental touch system 50 is in standby mode, plugging the external power supply into the power interface 101 will unlock the anti-accidental touch system 50.

[0115] Optionally, when the anti-accidental touch system 50 is in the unlocked state, if there is no operation on the child safety seat 1 (including operation buttons, adjusting the backrest tilt angle, adjusting the rotation position of the seat body 130, and engaging the ISOFIX connector, etc.) for more than a first predetermined time (e.g., 5 seconds, 10 seconds, etc.), the anti-accidental touch system 50 switches to the locked state. Referring to Figure 20b, when the anti-accidental touch system 50 switches to the locked state, the first display area 321 of the display 32 briefly displays a "button lock pattern".

[0116] Optionally, when the anti-accidental touch system 50 is in a locked state and the button is not operated for a period of time longer than a second predetermined time (e.g., 5 minutes, 10 minutes, etc.), the anti-accidental touch system 50 switches to a standby state.

[0117] Optionally, when the anti-mistouch system 50 is in the locked state and the time interval between pressing at least two different buttons is shorter than a third preset time (e.g., 0.5S, 1S, etc.), the anti-mistouch system 50 switches to the unlocked state. Referring to FIG20a, the right side of the first display area 321 of the display 32 displays a "button lock pattern," indicating that it is in the locked state. The left side of the first display area 321 of the display 32 provides a prompt to the user: first click the power button 311, then click the ventilation control button 312 to activate the input component 30, causing the anti-mistouch system 50 to switch to the unlocked state. After switching to the unlocked state, as shown in FIG20c, the first display area 321 of the display 32 briefly displays a "button unlock pattern." The various technical features of the above embodiments can be combined arbitrarily. For the sake of brevity, not all possible combinations of the various technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
