[0040] It should be noted that if an element is referred to as "fixed to" or "provided on" another element, it can be directly on the other element or there can be a mediating element. If an element is considered to be "connected" to another element, it can be directly connected to the other element or there can be a mediating element.

[0041] Referring to FIGS. 1, 2 and 3, the embodiments of the present application provide a child safety seat, which comprises a base 100, an inclination angle adjusting mechanism 200 and a seat body 130. The seat body 130 is slidably connected to the base 100; the inclination angle adjusting mechanism 200 is pivotally connected to the base 100 and drivably connected to the seat body 130 to drive the relative sliding of the seat body 130 relative to the base 100, thereby realizing the adjustment of the seat angle.

[0042] Specifically, as shown in FIG. 3, the inclination angle adjusting mechanism 200 comprises a transmission member 230, a driver 260 and a sliding block 220. The sliding block 220 is connected to the seat body 130 and detachably engaged with the transmission member 230; the driver 260 is drivably connected with the transmission member 230 to drive the transmission member 230 to move the sliding block 220. The movement of the sliding block 220 drives the sliding of the seat body 130 relative to the base 100, thereby realizing the adjustment of the seat angle.

[0043] In the child safety seat according to the embodiments of the present application, by providing the sliding block 220 which is detachably engaged with the transmission member 230 and connected to the seat body 130, the transmission member 230 is driven by the driver 260 to move the sliding block 220, the movement of the sliding block 220 drives the sliding of the seat body 130 relative to the base 100, thereby adjusting the seat angle, which simplifies the structural complexity of the angle adjusting mechanism of the child safety seat; on the other hand, the sliding block 220 is engaged with the transmission member 230, the transmission efficiency is high, the connection mode is simple, the installation difficulty is low, which helps to improve the assembly efficiency.

[0044] In one embodiment of the present application, the inclination angle adjustment mechanism 200 further comprises a bracket 210, which comprises a connecting end 2102 pivotally connected to the base 100 and a free end 2103 extending into the seat body 130. As shown in Figs. 1 and 3, the connecting end 2102 of the bracket 210 is provided with a pivot portion 211 having a pivot hole 2110, and a pivot shaft (not shown) is arranged in the pivot hole 2110 and a matching insertion hole (not shown) is arranged on the base 100, so that the bracket 210 can pivot around the pivot shaft.

[0045] In the embodiment shown in Fig. 3, the seat body 130 comprises a pushing rod 132 fixed on the seat body 130, which passes through the sliding block 220. The pushing rod 132 moves with the sliding block 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 around the pivot shaft arranged in the pivot hole 2110.

[0046] Referring to Figs. 1 and 2 simultaneously, the base 100 is provided with sliding rods 110 fixed on the base 100. In this embodiment, the number of the sliding rods 110 is two, and the two sliding rods 110 are arranged in parallel with each other. The seat body 130 is formed with two groups of second sliding grooves 131, each group of second sliding grooves 131 comprises two second sliding grooves 131 arranged opposite to each other. When the seat body 130 is installed on the base 100, each sliding rod 110 passes through one group of second sliding grooves 131 and can slide along the extension direction of the second sliding grooves 131, thereby guiding the seat body 130 to slide relative to the base 100.

[0047] In this embodiment, the transmission member 230 is a screw rod 231. The outer surface of the screw rod 231 is provided with threads.

[0048] The inclination angle adjustment mechanism 200 comprises a driver 260 fixedly connected with the bracket 210. In this embodiment, the driver 260 is arranged beside the pivot portion 211, and the driver 260 comprises a motor and a transmission mechanism (not shown) such as a gear, the axis of the rotating shaft (not shown) of the motor is arranged at an angle with the axis of the screw rod 231, and the rotation of the motor can drive the screw rod 231 to rotate through the transmission mechanism. In some other embodiments, the transmission member 230 can also be a gear, a rack or a chain, etc.

[0049] Referring to FIGS. 4A, 4B, 5A and 5B, the slider 220 includes an engaging member 240 provided with a threaded portion 241, and a driving block 270 connected to the engaging member 240 to drive the engaging member 240 to move. The engaging member 240 has a first position and a second position. As shown in FIG. 4A, the engaging member 240 is in the first position, and the threaded portion 241 of the engaging member 240 is engaged with the threads on the outer surface of the screw rod 231. Understandably, when the screw rod 231 rotates, the slider 220 can be driven to move along the axial direction of the screw rod 231 to change the position of the slider 220. As shown in FIG. 4B, the engaging member 240 is in the second position, and the threaded portion 241 of the engaging member 240 is disengaged from the threads on the outer surface of the screw rod 231. Understandably, the rotation of the screw rod 231 can no longer drive the slider 220 to move. Referring to FIGS. 5A and 5B, the engaging member 240 includes the threaded portion 241 and a main body 242 connected to each other. Optionally, the threaded portion 241 and the main body 242 are integrally formed.

[0050] Referring to FIGS. 4A, 4B, 6 and 7, the slider 220 is provided with a first channel 222 and a second channel 223. The screw rod 231 is arranged in the first channel 222, and the engaging member 240 is arranged in the second channel 223 and can reciprocate in the second channel 223. For example, the slider 220 shown in FIGS. 4A and 7, the first channel 222 is closer to the bottom of the slider 220 and extends through the slider 220 along the horizontal direction H, and the second channel 223 is arranged in the middle of the slider 220 along the vertical direction V, and the bottom end of the second channel 223 is in communication with the first channel 222, so that the engaging member 240 can be engaged with the screw rod 231 in the first channel 222. The first channel 222 and the second channel 223 are arranged in perpendicular to each other, and the engaging effect of the engaging member 240 and the screw rod 231 is good. In some embodiments, the engaging member 240 engages the screw rod 231 from one side direction, i.e., the threaded portion 241 only engages a part of the peripheral surface of the screw rod 231. Since the screw rod 231 and the slider 220 are both fixed on the bracket 210, and the screw rod 231 is limited in the first channel 222 and the engaging member 240 is limited in the second channel 223, the threaded portion 241 only needs to engage a part of the peripheral surface of the screw rod 231 to provide appropriate engagement force, thereby simplifying the structure.

[0051] In other embodiments, the extension direction of the second channel 223 and the extension direction of the first channel 222 can also not be perpendicular, but be at an angle, which can be an acute angle or an obtuse angle. In this way, the opposite two edges of the slider 220 can not be equal in length, so as to reduce the volume of the slider 220, so that the structure of the slider 220 is more compact, which is beneficial to use in a smaller space.

[0052] With reference to FIGS. 4A, 4B, 6 and 7, the slider 220 is further provided with a third channel 224. The driving block 270 is formed as a substantially cuboid structure, and is arranged in the third channel 224 and can slide along the third channel 224. Taking the slider 220 shown in FIG. 7 as an example, the third channel 224 is closer to the top of the slider 220, and extends along the horizontal direction H through the slider 220. The middle part of the third channel 224 is in cross communication with the second channel 223, so that the driving block 270 is simultaneously located in the second channel 223 and the third channel 224.

[0053] The driving block 270 can reciprocate in the third channel 224 along the extension direction of the third channel 224, and can be moved to a third position as shown in FIG. 4A, i.e., the driving block 270 is moved to the right along the third channel 224; the driving block 270 can also be moved to a fourth position as shown in FIG. 4B, i.e., the driving block 270 is moved to the left along the third channel 224. Here, the orientation terms "left" and "right" are referred to the orientation shown in FIGS. 4A and 4B.

[0054] The driving block 270 is provided with a driving slot 2701, and the clamping member 240 is fixedly provided with a driving rod 2401 which is inserted into the driving slot 2701, and the extension direction of the driving rod 2401 is not parallel to the extension direction of the first channel 222. Specifically, with reference to FIGS. 4A, 4B, 5A and 5B, in the direction away from the pivot portion 211 along the third channel 224, the driving slot 2701 is inclined away from the first channel 222.

[0055] With reference to FIG. 4A and FIG. 7, when the driving block 270 moves in the third channel 224 towards the third position, the driving groove 2701 also moves towards the third position. In this process, under the driving of the inner wall of the driving groove 2701, the driving rod 2401 gradually approaches the first channel 222, i.e., the driving rod 2401 and the engaging member 240 gradually move towards the first position. When the driving block 270 reaches the third position, the engaging member 240 reaches the first position, thereby the engaging member 240 engages with the screw rod 231. At this time, the adjustment of the seat angle can be realized by the driving of the driver 260, and the angle adjustment mechanism of the child safety seat is in the automatic adjustment mode. Similarly, with reference to FIG. 4B and FIG. 7, when the driving block 270 moves in the third channel 224 towards the fourth position, the driving groove 2701 also moves towards the fourth position. In this process, under the driving of the inner wall of the driving groove 2701, the driving rod 2401 gradually moves away from the first channel 222, i.e., the driving rod 2401 and the engaging member 240 gradually move towards the second position. When the driving block 270 reaches the fourth position, the engaging member 240 reaches the second position, thereby the engaging member 240 disengages from the screw rod 231. At this time, the adjustment of the seat angle cannot be realized by the driving of the driver 260, and can be realized by manual adjustment of the user, and the angle adjustment mechanism of the child safety seat is in the manual adjustment mode. In this way, the angle adjustment mechanism of the child safety seat described in the present application can drive the engaging member 240 to engage or disengage with the screw rod 231 through the driving block 270, so as to switch the angle adjustment mechanism of the child safety seat between the automatic adjustment mode and the manual adjustment mode.

[0056] The driving block 270 is also provided with a positioning groove 2702, which is in communication with the driving groove 2701, and is used to limit the relative movement of the driving rod 2401 in the driving groove 2701, so that the position of the driving rod 2401 in the driving groove 2701 is relatively fixed. With reference to FIG. 5A and FIG. 5B, the positioning groove 2702 is in communication with one end of the driving groove 2701 close to the first channel 222, and in the present embodiment, the extension direction of the positioning groove 2702 is parallel to the extension direction of the first channel 222. With reference to FIG. 4A, FIG. 5A and FIG. 5B, when the driving block 270 is located at the third position, the driving rod 2401 is located in the positioning groove 2702. Since the extension direction of the positioning groove 2702 is arranged at an angle with the extension direction of the driving groove 2701, the driving rod 2401 can be relatively stably stopped at the third position, reducing the probability of the driving block 270 accidentally leaving the third position under the condition of shaking, overturning or collision, and helping the engaging member 240 to maintain the engagement state with the screw rod 231 to keep the seat angle.

[0057] The tilt angle adjusting mechanism 200 further comprises a reset member 250. Referring to FIGS. 4A and 4B, the slider 220 is further provided with a stop portion 226 fixedly arranged on the left side of the slider 220, and part of the stop portion 226 is located in the extending direction of the third channel 224. The reset member 250 is arranged between the stop portion 226 and the driving block 270, one end of the reset member 250 abuts against the driving block 270, and the other end abuts against the stop portion 226. The reset member 250 continuously applies a pushing force to the driving block 270 in the direction away from the stop portion 226, so that the driving block 270 always has a tendency to move to the third position. By arranging the reset member 250, the driving block 270 is moved to the third position, which helps the engaging member 240 and the screw rod 231 to be stably kept in the engaged state; on the other hand, the reset member 250 can also make the engaging member 240 and the screw rod 231 automatically recover the engaged state after being disengaged.

[0058] In the embodiment, the reset member 250 is a compression spring, which has a low cost and can stably apply the pushing force to the driving block 270. The compression spring is always kept in a compressed state between the stop portion 226 and the driving block 270, so as to continuously apply the pushing force to the driving block 270. Alternatively, the reset member 250 can also be other suitable structures, such as a spring piece, a torsion spring, etc., as long as it can stably apply the pushing force to the driving block 270.

[0059] In some other embodiments, the two ends of the reset member 250 can be fixedly connected with the driving block 270 and the stop portion 226 respectively, so as to reduce the probability that the reset member 250 is disengaged from the driving block 270 and the stop portion 226, and to more stably and continuously apply the pushing force to the driving block 270.

[0060] In the embodiment, the stop portion 226 is fixedly connected with the slider 220 by a screw. In some other embodiments, the stop portion 226 can also be connected with the slider 220 by bonding, welding, etc. The stop portion 226 can also be integrally formed with the slider 220, so that the stop portion 226 is better fixed on the slider 220.

[0061] The tilt angle adjusting mechanism 200 further comprises a connecting member 290 and an operating member 280, so as to remotely drive the driving block 270 to move in the third channel 224.

[0062] Referring to FIGS. 2, 4A and 4B, specifically, the operation member 280 is arranged on the seat body 130, one end of the connecting member 290 is connected with the operation member 280, and the other end of the connecting member 290 is connected with the driving block 270. Exemplarily, the connecting member 290 is a steel wire, the operation member 280 pulls the steel wire, the steel wire pulls the driving block 270 to overcome the pushing force of the reset member 250 and moves the driving block 270 to the fourth position, thereby making the engaging member 240 disengage with the screw rod 231, and allowing the slider 220 to move freely along the axis direction of the screw rod 231. At this time, the angle adjusting mechanism of the child safety seat is in the manual adjusting mode, and the user can manually adjust the angle of the seat body 130.

[0063] Referring to FIG. 3, the stop portion 226 is provided with a through slot 2261, which is aligned with the reset member 250 in the extension direction of the third channel 224, and the through slot 2261 is for the connecting member 290 to pass through. In this embodiment, during installation, the steel wire is first passed through the through slot 2261, and then passed through the spring along the axis direction of the spring, and then connected with the driving block 270. The through slot 2261 can limit the connecting member 290, prevent the connecting member 290 from swinging, and improve the sensitivity of switching to the manual adjusting mode.

[0064] Continuing to refer to FIG. 3, the bracket 210 includes two oppositely arranged limiting frames 212, which are spaced apart to form a first sliding groove 2101. At least a part of the slider 220 is located in the first sliding groove 2101, so that the slider 220 is limited by the two limiting frames 212 to move along the extension direction of the first sliding groove 2101. The screw rod 231 is parallel to the extension direction of the first sliding groove 2101, so as to smoothly drive the slider 220 to move along the first sliding groove 2101, and reduce the probability of jamming.

[0065] The slider 220 is also provided with a connecting portion 227, and the push rod 132 is arranged in the connecting portion 227. In this embodiment, referring to FIGS. 1, 3 and 6 simultaneously, the connecting portion 227 protrudes from the surface of the slider 220, and has better support for the push rod 132. The connecting portion 227 is provided with a connecting hole 2271, which is parallel to the extension direction of the sliding rod 110. The push rod 132 is arranged in the connecting hole 2271, and is kept in a nearly parallel state with the sliding rod 110 under the limiting action of the annular inner wall corresponding to the connecting hole 2271, thereby reducing the probability of jamming when adjusting the angle of the seat.

[0066] Further, the connecting portion 227 is provided with a detection protrusion 2273. Referring to FIGS. 1, 3 and 6, the bracket 210 is further provided with a limiting clip 213, which in the present embodiment is arranged on the limiting frame 212 close to the driver 260 and on the side of the limiting frame 212 away from the screw rod 231. Optionally, the position detector 2130 can include a first position detector 2131 and a second position detector 2132. The first position detector 2131 is arranged on the side of the limiting clip 213 close to the connecting end, and the second position detector 2132 is arranged on the side of the limiting clip 213 close to the free end. Optionally, the position detector 2130 can further include a third position detector 2133. The third position detector 2133 is arranged between the two opposite ends of the limiting clip 213 and 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 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 rod 231. By arranging the position detector 2130, the stroke 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.

[0067] FIGS. 10 to 16 show an angle adjustment mechanism of a child safety seat according to another embodiment of the present application. Hereinafter, only the differences between the angle adjustment mechanism of the child safety seat according to the present embodiment and the angle adjustment mechanisms of the child safety seats in the foregoing embodiments will be described.

[0068] Referring to FIG. 11, in the present embodiment, the base 100 is provided with a power interface 101 for connecting an external power supply to power the components of the child safety seat. For example, the external power supply powers the motor in the driver 260 via the power interface 101. Optionally, the power interface can be any electrical interface known in the art, such as a DC interface, a USB interface, a lighting interface, etc. In the embodiment shown in FIG. 11, the power interface 101 is a USB Type-C interface. In addition, in the present embodiment, the power interface 101 is located on the bottom of the base 100 close to the support leg, which on the one hand can avoid the child seated in the child safety seat from kicking the power cord, and on the other hand can avoid the power cord from interfering with the vehicle seat when the child safety seat is installed on the vehicle seat.

[0069] Referring to FIG. 12, in the present embodiment, the support 210 of the inclination angle adjustment mechanism 200 includes a connecting end 2102 pivotably connected to the base 100 and a free end 2103 opposite the connecting end 2102, i.e., the support 210 is disposed in the base 100 in a substantially "lying down" manner. When adjusting the angle of the seat, the driver 260 drives the screw rod 231 to pivot, and the pivoting of the screw rod 231 drives the sliding block 220 to move along the axis direction of the screw rod 231, thereby the sliding block 220 drives the seat body 130 to slide relative to the base 100 via the pushing rod 132 (see FIG. 13) disposed on the seat body 130.

[0070] Referring to FIG. 14 and FIG. 15, when the seat body 130 slides relative to the base 100, the seat body 130 moves to form a generally circular arc-shaped movement trajectory. In the plane in which the circular arc-shaped movement trajectory lies, an angle defined by a virtual line L1 between a center O of the circular arc and the push rod 132 intersecting with a direction L2 of the driving force F acting on the push rod 132 and pointing towards the front of the seat body 130 is defined as an acting angle a. In the present application, the front of the seat body 130 refers to a portion of the seat body 130 facing away from the backrest, and correspondingly, the rear of the seat body 130 refers to a portion of the seat body 130 where the backrest is located. As shown in FIG. 14, the seat body 130 is in a lying state, and at this time, the connecting end 2102 and the free end 2103 of the bracket 210 are generally at the same height in the vertical direction V, so that the bracket 210 is in a generally “flat lying” posture. At this time, the acting angle a is a maximum value. Optionally, the maximum value of the acting angle a is 94°. In the process of switching the seat body 130 from the lying state shown in FIG. 14 to the upright state shown in FIG. 15, as the seat body 130 slides relative to the base 100, the bracket 210 is pivoted, the free end 2103 of the bracket 210 gradually rises in the vertical direction V, and the acting angle a gradually decreases. When the seat body 130 reaches the upright state shown in FIG. 15, in the vertical direction V, the height of the free end 2103 of the bracket 210 is greater than the height of the connecting end 2102, so that the bracket 210 is in a generally “inclined lying” posture. At this time, the acting angle a is a minimum value. Optionally, the minimum value of the acting angle a is 78°. Those skilled in the art can understand that a component of the driving force F perpendicular to the virtual line L1 can drive the seat body 130 to slide, and therefore, the closer the acting angle a is to 90°, the greater the component is, and the higher the acting efficiency of the driving force F is. When the acting angle a is equal to 90°, the driving force F is completely used to drive the seat body 130 to slide, at this time, the seat body 130 can be driven to slide with the smallest driving force F, and the acting efficiency of the driving force F is the highest. In the present embodiment, when the seat body 130 is switched between the lying state and the upright state, the acting angle a is always close to 90°, for example, the acting angle a is in the range of 78° to 98°, so that the driving force F always has a high acting efficiency, making the sliding of the seat body 130 more smooth, and the load on the driver 260 smaller, which is beneficial to prolong the service life of the angle adjustment mechanism of the child safety seat and reduce the failure rate.

[0071] Referring to FIG. 12 again, in the present embodiment, the connecting end 2102 of the bracket 210 is provided with a pivot shaft 2104, the base 100 is provided with mounting ribs 1201 and mounting seats 1202, and the mounting ribs 1201 are provided with through holes 12011. The end of the pivot shaft 2104 passes through the through hole 12011, and the pivot shaft 2104 is fixed on the mounting seat 1202. Specifically, the base 100 is provided with two groups of mounting ribs 1201, each group of mounting ribs 1201 includes two mounting ribs 1201, and each sliding rod 110 passes through a group of mounting ribs 1201 to be fixed on the base 100. Optionally, the mounting ribs 1201 are formed of a metal sheet, for example, a sheet of iron. One of the mounting ribs 1201 is provided with a through hole 12011, the first end of the pivot shaft 2104 passes through the through hole 12011, and the second end of the pivot shaft 2104 opposite to the first end is fixedly connected to the mounting seat 1202, so that the connecting end 2102 is pivotably connected to the base 100. Optionally, the base 100 is provided with two mounting seats 1202, the first end of the pivot shaft 2104 is accommodated in or fixed on one of the mounting seats 1202 after passing through the through hole 12011, and the second end of the pivot shaft 2104 is fixedly connected to the other mounting seat 1202.

[0072] Referring to FIGS. 12 and 16, the mounting seat 1202 is provided with a mounting groove 1203, and the end of the pivot shaft 2104 is accommodated in the mounting groove 1203. Specifically, in the embodiment shown in FIG. 16, the first end of the pivot shaft 2104 is accommodated in the mounting groove 1203 of one of the mounting seats 1202 after passing through the through hole 12011, and a part of the second end of the pivot shaft 2104 is accommodated in the mounting groove 1203 of the other mounting seat 1202, and the other part of the second end of the pivot shaft 2104 is fixed on the other mounting seat 1202 by the fixing member 400. Optionally, the fixing member 400 can be any fixing device such as a screw, a rivet, a fixing pin, etc. Optionally, a part 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 seat 1202, and the other part of the first end of the pivot shaft 2104 passing through the through hole 12011 is fixed on the mounting seat 1202. Optionally, the end of the pivot shaft 2104 can also be fixed on the mounting seat 1202 without the fixing member 400, and the end of the pivot shaft 2104 can be fixed on the mounting seat 1202 by, for example, magnetic attraction connection, adhesion, welding, etc.

[0073] With continued reference to FIG. 16, in the present embodiment, the end of the pivot shaft 2104 is sleeved with a shock-absorbing sleeve 2105, which is located between the end of the pivot shaft 2104 and the mounting groove 1203. Specifically, the shock-absorbing sleeve 2105 is sleeved on the portions of the first end and the second end of the pivot shaft 2104 accommodated in the mounting groove 1203, so as to buffer the vibration 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 the noise and mechanical wear caused by the vibration, optimizing the ride experience of the occupant, and prolonging the service life of the angle adjustment mechanism of the child safety seat. Optionally, the shock-absorbing sleeve 1205 is made of, for example, silica gel material. In some embodiments, the base 100 further comprises a rotating seat 120. With reference to FIGS. 8-11, the rotating seat 120 is rotatably arranged on the base 100, and the inclination 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 adjust the direction facing the occupant, thereby improving the convenience of use.

[0074] With reference to FIGS. 17, 18, 27 and 28, according to one embodiment of the present application, a child safety seat 1 is provided, which comprises a seat body 130, a base 100, and a seat posture adjustment assembly 20 arranged 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. Illustratively, the seat posture adjustment assembly 20 comprises at least one of a rotating position adjustment mechanism for adjusting the rotating position of the seat body 130 and an inclination angle adjustment mechanism 200 for adjusting the inclination angle of the seat body 130. As shown in FIG. 27, the rotating position adjustment mechanism comprises a rotating disc 72 connected to the seat body 130, the seat body 130 is connected to the rotating disc 72, and the rotating disc 72 is pivotally connected to the base 100. Thus, the seat body 130 is pivotally connected to the base 100 through the rotating disc 72, and the seat body 130 can freely rotate relative to the base 100. In addition, the rotating disc 72 is further provided with a retractable engagement pin 513, and the base 100 is provided with a plurality of engagement holes 510 matched with the engagement pin 513. When the engagement pin 513 is inserted into the engagement hole 510, the seat body 130 can be locked in a forward position (as shown in FIG. 17) and a rearward position (as shown in FIG. 18) relative to the base 100. With reference to FIGS. 27 and 28, optionally, the seat posture adjustment assembly 20 comprises the inclination angle adjustment mechanism 200 to realize the sliding of the seat body 130 relative to the base 100 in the W1 and W2 directions shown in FIG. 17, so as to adjust the inclination angle of the backrest of the seat body 130, thereby realizing the switching between the upright mode and the lying mode.

[0075] Referring to FIG. 17 and FIG. 19, in the present embodiment, the front end of the base 100 is provided with an input assembly 30. Alternatively, the input assembly 30 can also be provided at other suitable positions of the child safety seat 1, for example, on the seat body 130. Alternatively, the input assembly can also be other suitable mechanisms as long as control commands can be inputted. FIG. 19 shows a schematic structure of the input assembly 30 in FIG. 17. In the embodiment shown in FIG. 19, the input assembly 30 comprises a plurality of keys 31 and a display screen 32. Alternatively, the input assembly 30 can also comprise at least one of the keys 31 or the display screen 32. Alternatively, the display screen 32 can be a touch screen, and the user can input control commands by touching virtual buttons displayed on the touch screen. The keys 31 specifically comprise, in the present embodiment, a power key 311, a ventilation control key 312, and two seat inclination angle adjustment keys 313. The power key 311 is used to control the input assembly 30 to enter a release lock state or a standby state. The ventilation control key 312 is used to control the opening and closing of the fan of the seat ventilation device 71 (see FIG. 27), and is used to adjust the wind speed. One of the seat inclination angle adjustment keys 313 is used to control the increase of the inclination angle of the backrest of the seat body 130, and the other is used to control the decrease of the inclination angle of the backrest of the seat body 130. It should be noted that the power key 311, the ventilation control key 312, and the two seat inclination angle adjustment keys 313 shown in FIG. 19 are only exemplary, and those skilled in the art can set other suitable keys on the input assembly 30 according to needs, for example, a display screen brightness adjustment key, a seat ventilation device power adjustment key, etc. Alternatively, the keys 31 can be touch keys or mechanical keys. The keys 31 provided on the base 100 or the seat body 130 are easy to be mistakenly touched or operated by the child seated in the child safety seat 1, which causes the ventilation and electrically-controlled inclination angle adjustment functions of the child safety seat 1 to be accidentally started, causing inconvenience to the user.

[0076] Referring to FIG. 19 and FIG. 20a, in an embodiment of the present application, the display screen 32 comprises a first display area 321 and a second display area 322, and the first display area 321 and the second display area 322 can display different interfaces respectively. The interface content displayed by the display screen 32 will be described below in combination with FIG. 20a to FIG. 22b.

[0077] Referring to FIGS. 23a, 23b, 25a and 25b, in an embodiment of the present application, the anti-mis-touch system 50 of the child safety seat 1 comprises a seat posture detection module 51 and a control module 52. The seat posture detection module 51 is arranged on the seat body 130 or the base 100 to detect the seat posture of the seat body 130. In an embodiment of the present application, the term “seat posture” includes at least one of the rotational position of the seat body 130 and the reclining angle of the backrest of the seat body 130. The control module 52 is electrically connected to the input assembly 30 and the seat posture detection module 51. The control module 52 can disable the input assembly 30 in response to the seat posture not changing within a preset time. For example, when powered by the built-in battery only, and the seat posture does not change within 5 minutes, the control module 52 will disable the input assembly 30, so that the corresponding function cannot be triggered by the input assembly 30, thereby avoiding accidental triggering of the seat function due to mis-touch. For example, when the seat posture changes, the control module 52 will activate the input assembly 30, so that the corresponding function can be triggered by the input assembly 30. It can be understood by those skilled in the art and personnel that the child seated in the seat body 130 cannot change the seat posture by himself / herself, so that the child can effectively avoid mis-operating the input assembly 30.

[0078] In one embodiment of the present application, the child safety seat 1 has a standby state, an unlock state and a lock state. In the unlock state, the standby state can be entered by long-pressing the power button 311, for example. In the standby state, the child safety seat 1 is powered by the built-in battery, and the power supply to the components with high power consumption, such as the display screen 32, the fan of the ventilation device 71 and the driver 260 of the reclining angle adjustment mechanism 200, is cut off, and the microcontroller of the control module 52 enters a low-power mode to save power consumption. Optionally, the driver 260 can include a motor and a transmission mechanism (not shown in the figure) such as a gear. At this time, the user cannot turn on the fan or adjust the reclining angle of the backrest by pressing the button 31, and the control module 52 only responds to the power-on input signal (i.e., the first unlock operation) from the power button 311, the external power supply interface (e.g., the power supply interface 101, refer to FIG. 27), the in-place sensor 531 and the position detector 2130 of the seat posture detection module 51, etc. The power-on input signal can be generated in one or more of the following ways: (1) long-pressing the power button 311; (2) connecting the external power supply; (3) the in-place sensor 531 detects that either of the ISOFIX connectors 532 on the left or right side reaches the preset plug-in position in the ISOFIX socket; (4) the forward sensor 511 detects that the seat body 130 is in the forward position or the rearward sensor 512 detects that the seat body 130 is in the rearward position; (5) the angle sensor detects that the reclining angle of the backrest of the seat body 130 relative to the base changes. When the power-on input signal is received in the standby state, the child safety seat 1 switches from the standby state to the unlock state, and the power supply to the display screen 32, etc. is turned on. In the unlock state, the user can turn on the fan or adjust the reclining angle of the backrest by inputting components 30, such as by pressing the button 31. In the lock state, the control module 52 does not respond to any input signal other than the unlock signal, to avoid accidental triggering of the seat functions due to accidental touch, and the functions such as the running fan will not be turned off due to interruption of power supply.

[0079] Specifically, in the lock state and the standby state, the input assembly 30 is disabled so as not to trigger the function, and in the unlock state, the input assembly 30 is activated so as to trigger the function. When the anti-mis-touch system 50 is in the standby state, the control module 52 controls the anti-mis-touch system 50 to enter the unlock state in response to a first unlock operation to activate the input assembly 30, and when the anti-mis-touch system 50 is in the lock state, the control module 52 controls the anti-mis-touch system 50 to enter the unlock state in response to a second unlock operation to activate the input assembly 30. Optionally, the first unlock operation is a manual adjustment of the seat posture, and the second unlock operation is inputting a specific combination of input operations through the input assembly 30. For example, the specific combination of input operations through the input assembly 30 is pressing two different keys 31 within a third preset time. Optionally, the third preset time can be 0.5S, 1S, etc. Those skilled in the art can understand that 0.5S and 1S are only exemplary, and those skilled in the art can select a suitable time length for the third preset time according to actual needs. In the embodiment, the two different keys 31 need to be pressed within, for example, 0.5S to make the anti-mis-touch system 50 change to the unlock state, so that accidental activation of the input assembly 30 due to mis-touch of the keys 31 can be avoided. Optionally, in an embodiment of the present application, when the anti-mis-touch system 50 is in the unlock state, the anti-mis-touch system 50 changes to the lock state to disable the input assembly 30 in response to a time of no operation of the input assembly 30 being greater than a first predetermined time. Optionally, the first predetermined time can be 5S, 10S, etc. Those skilled in the art can understand that 5S and 10S are only exemplary, and those skilled in the art can select a suitable time length for the first predetermined time according to actual needs. Optionally, in an embodiment of the present application, when the anti-mis-touch system 50 is in the lock state, the anti-mis-touch system 50 changes to the standby state to disable the input assembly 30 in response to a time of no operation of the input assembly 30 being greater than a second predetermined time. Optionally, the second predetermined time can be 5 minutes, 10 minutes, etc. Those skilled in the art can understand that 5 minutes and 10 minutes are only exemplary, and those skilled in the art can select a suitable time length for the second predetermined time according to actual needs.

[0080] In an embodiment of the present application, the anti-mis-touch system 50 further comprises an ISOFIX detection mechanism 53 for detecting whether the ISOFIX connectors 532 reach the preset plug-in position in the ISOFIX sockets. The ISOFIX detection mechanism 53 comprises a position sensor 531. When the position sensor 531 detects that the ISOFIX connectors 532 reach the preset plug-in position in the ISOFIX sockets, the position sensor 531 outputs a position signal to the control module 52. When the anti-mis-touch system 50 is in the standby state and the control module 52 receives the position signal, the control module 52 switches the anti-mis-touch system 50 to the unlocked state to activate the input assembly 30. Specifically, referring to FIG. 18, the ISOFIX detection mechanism 53 is arranged on the left and right ISOFIX connectors 532. For the sake of simplicity, the left ISOFIX connector 532 is taken as an example for description. When the position sensor 531 detects that the left ISOFIX connector 532 of the base 100 reaches the preset plug-in position in the ISOFIX socket (not shown) on the left side of the rear seat of the vehicle, the position sensor 531 outputs a position signal to the control module 52, and if the anti-mis-touch system 50 is in the standby state at this time, the control module 52 activates the input assembly 30 and switches the anti-mis-touch system 50 to the unlocked state. In this way, when the user installs the child safety seat 1 to the rear seat of the vehicle through the ISOFIX connectors 532, as long as either the left ISOFIX connector or the right ISOFIX connector is plugged in place, the anti-mis-touch system 50 can be switched from the standby state to the unlocked state to activate the input assembly 30, without the need for manual state switching, thereby improving the convenience of use. Alternatively, the control module 52 can be configured to switch the anti-mis-touch system 50 to the unlocked state to activate the input assembly 30 only when both left and right ISOFIX connectors 532 are plugged in place. Alternatively, the display screen 32 can display the plug-in state of the ISOFIX connectors 532. For example, as shown in FIG. 21d, when both left and right ISOFIX connectors 532 are not plugged in place, the a, β, and γ areas are displayed in red; when only the right ISOFIX connector 532 is plugged in place, the a and γ areas are displayed in red and the β area is displayed in green; when only the left ISOFIX connector 532 is plugged in place, the β and γ areas are displayed in red and the a area is displayed in green; and when both left and right ISOFIX connectors 532 are plugged in place, the a, β, and γ areas are all displayed in green. Alternatively, in this embodiment, the position sensor 531 is a travel switch, and the base 100 is respectively provided with a second driving member 533 on the left and right sides. When the hook of the ISOFIX connector 532 pivots and engages with the clamping rod of the ISOFIX interface of the seat of the vehicle, the second driving member 533 cooperating with the hook moves with the pivoting of the hook and abuts against the travel switch to touch the travel switch, and the travel switch outputs a position signal to the control module 52.

[0081] In an embodiment of the present application, the base 100 is further provided with a battery (not shown) for powering the input assembly 30 and the anti-mistaken-touch system 50. Optionally, when the anti-mistaken-touch system 50 is in the locked state or the unlocked state, and the battery power is lower than a preset value, the display screen displays information of low power, for example, as shown in FIG. 22a. Optionally, the input assembly 30 is provided with a power interface 101 (see FIG. 27) which is electrically connected with the control module 52, for connecting an external power source. The external power source is used for powering, for example, the ventilation device 71 and the seat posture adjustment assembly 20. In an embodiment in which the battery is a rechargeable battery, the external power source can also be used for charging the battery. In such an embodiment, compared with the case of connecting the external power source, in the case of not connecting the external power source, the second predetermined time will be shorter, for example, the second predetermined time can be 1 minute, 3 minutes, etc., so as to enter the standby state faster and save the battery power.

[0082] With reference to FIGS. 24 and 25b, in an embodiment of the present application, the child safety seat 1 further comprises a wireless receiving module and a remote controller 60. The wireless receiving module is provided, for example, on the child safety seat 1 and is electrically connected with the control module 52. The remote controller 60 is wirelessly connected in communication with the wireless receiving module. In such an embodiment, the input assembly 30 comprises the remote controller 60. Optionally, the remote controller 60 is provided with a plurality of remote control keys, which in the present embodiment comprise a ventilation key 611, a ventilation off key 612, a seat upright key 613, a seat reclining key 614, and two seat reclining angle adjustment keys 615. Specifically, pressing the ventilation off key 612 turns off the seat ventilation device 71. Pressing the ventilation key 611 turns on the seat ventilation device 71, and pressing the ventilation key 611 again switches the seat ventilation device 71 among the high-speed ventilation mode, the medium-speed ventilation mode and the low-speed ventilation mode in turn. Pressing the seat upright key 613 gradually reduces the reclining angle of the seat body 130 to make the seat body 130 reach the upright mode. Pressing the seat reclining key 614 gradually increases the reclining angle of the seat body 130 to make the seat body 130 reach the lying mode. The two seat reclining angle adjustment keys 615 respectively control the seat body 130 to rotate in the direction of increasing the reclining angle and decreasing the reclining angle, i.e., pressing one of the seat reclining angle adjustment keys 615 changes the seat angle by one step.

[0083] Optionally, the remote controller 60 can also have a pairing function, and through pairing, the remote controller 60 can be paired with the wireless receiving module. In an embodiment, the pairing mode is as follows: when the input assembly 30 is in the activated state, first press the pairing key 33 on the input assembly 30, and then press any remote control key within a set time, for example, 8 seconds, 10 seconds, etc., to complete the pairing.

[0084] In another embodiment, optionally, the control module 52 is configured to disable the remote controller 60 in response to no operation within a preset time; the control module 52 activates the remote controller 60 in response to a second unlocking operation. The second unlocking operation includes inputting a specific combination of input operations through the remote controller 60. For example, the specific combination of input operations through the remote controller 60 is pressing two different remote control buttons within a fourth preset time. Optionally, the fourth preset time can be 0.5S, 1S, etc. Those skilled in the art can understand that 0.5S and 1S are only exemplary, and those skilled in the art can select a suitable time length for the fourth preset time according to actual needs. In this way, accidental execution of the corresponding function due to accidental touch of the remote control button can be avoided, and inconvenience to the user can be avoided.

[0085] In an embodiment of the present application, the child safety seat 1 is further provided with a prompter. The prompter is arranged in the seat body 130 or the base 100, for example, and is electrically connected to the control module 52. Optionally, the prompter is a buzzer that can emit a sound prompt signal. The buzzer emits a buzzing sound when certain specific events occur. For example, the buzzer emits a buzzing sound when the remote controller 60 is successfully paired; or the buzzer emits a buzzing sound with a long duration (more than 1S, for example, for 2S, 5S, etc.) when the anti-misoperation system 50 enters or exits the standby state.

[0086] Referring to FIG. 25b, in an embodiment of the present application, the control module 52 comprises 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 control board and the second control board are electrically connected by, for example, an electric slip ring (not shown). In the embodiment, the seat posture detection module 51 comprises 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, the tilt angle detection mechanism comprises an angle sensor, which is electrically connected to the control module 52. Optionally, the angle sensor is a Hall sensor, which outputs a tilt angle change signal to the control module 52 when the Hall sensor detects a change in the tilt angle of the seat body 130. If the anti-mis-touch system 50 is in the standby state at this time, the control module 52 activates the input assembly 30, and the anti-mis-touch system 50 switches to the unlocked state. For example, when the seat body 130 is manually adjusted in tilt angle before a child sits on the seat body 130 in order to adapt to safety and comfort, the input assembly 30 is automatically activated, and the anti-mis-touch system 50 switches to the unlocked state, thereby improving the convenience of use. In other embodiments, the angle sensor can also be a gyroscope or other sensor that can sense angle changes. The orientation detection mechanism is used to detect the rotation position of the seat body 130, and the orientation detection mechanism is electrically connected to the first control board. The ISOFIX detection mechanism is, for example, the ISOFIX detection mechanism 53 in the foregoing embodiments, which is electrically connected to the first control board. Optionally, the third control board is disposed in the input assembly 30 and is electrically connected to the first control board.

[0087] Referring to FIG. 26 and FIG. 27, in one embodiment of the present application, the orientation detection mechanism comprises a front sensor 511, a back sensor 512 and a detection protrusion 513. The front sensor 511 and the back sensor 512 are oppositely arranged in the base 100, and the detection protrusion 513 is arranged on the rotating disc 72 of the seat body 130 and can rotate with the rotation of the seat body 130. Optionally, the retractable engagement pin 513 arranged on the rotating disc 72 can be used as the detection protrusion 513. Exemplarily, the front sensor 511 and the back sensor 512 are leaf switches. When the seat body 130 is in the forward position, the detection protrusion 513 extends into the engagement hole 510 arranged at the rear of the base 100, presses and triggers the front sensor 511 to output a forward position signal to the control module 52; when the seat body 130 is in the backward position, the detection protrusion 513 extends into the engagement hole 510 arranged at the front of the base 100, presses and triggers the back sensor 512 to output a backward position signal to the control module 52. Specifically, when the anti-mis-touch system 50 is in the standby state, the user manually rotates the seat body 130 to change the rotation position of the seat body 130, when the seat body 130 is rotated to and locked in the forward position (or the backward position), the front sensor 511 (or the back sensor 512) is triggered by the detection protrusion 513 to input a forward position signal (or a backward position signal) to the control module 52, the control module 52 activates the input assembly 30, and restores the power supply to the display screen, the fan and the driving motor and other components, and the anti-mis-touch system 50 enters the unlocked state. Thus, the unlocked state can be quickly released, and the use convenience is improved. Optionally, the display screen displays that the base 100 is currently in the forward mode, as shown in FIG. 21a. Specifically, when the anti-mis-touch system 50 is in the standby state, the control module 52 receives the backward position signal, the control module 52 activates the input assembly 30, and the anti-mis-touch system 50 enters the unlocked state. Optionally, the display screen displays that the base 100 is currently in the backward mode, as shown in FIG. 21b.

[0088] In other embodiments, the orientation detection mechanism can further comprise a side sensor (not shown). When the seat body 130 is in the side position, the detection protrusion 513 triggers the side sensor to output a side position signal to the control module 52. When the anti-mis-touch system 50 is in the standby state, the control module 52 receives the side position signal, the control module 52 activates the input assembly 30, and the anti-mis-touch system 50 enters the unlocked state. Optionally, the display screen displays that the base 100 is currently in the side mode, as shown in FIG. 21c.

[0089] With reference to FIGS. 26 and 27, in the present embodiment, the seat posture detection module 51 comprises a fixed seat 516, a first driving member 517, a trigger spring 519, a front sensor 511, and a rear sensor 512. The front sensor 511 and the rear sensor 512 are the same sensor. Specifically, the front sensor 511 and the rear sensor 512 are a travel switch, which can be electrically connected with the control module 52 through, for example, an electric wire or other electrical connection. The fixed seat 516 is fixedly installed on the base 100, which is provided with a clamping hole 510, and the first driving member 517 is in the form of a column and coaxially arranged in the clamping hole 510. The first driving member 517 is provided with the trigger spring 519 on the side thereof, and the front sensor 511 is arranged beside the trigger spring 519 on the side of the first driving member 517. The end of the first driving member 517 is further provided with a reset spring 518 abutting against the base 100. The bottom side of the seat body 130 is provided with a detection protrusion 513 in the form of a clamping pin, for example, and the side of the detection protrusion 513 is annularly provided with a ring connecting portion 514.

[0090] In other embodiments, the front sensor 511 and the rear sensor 512 can also be a pair of sensors. When the seat body 130 is rotated into position, the detection protrusion 513 moves out to block the light beam of the pair of sensors, triggering the pair of sensors, which in turn outputs a position signal to the control module 52, so as to selectively activate the input assembly 30 according to the rotation position of the seat body 130, so that the mistaken touch prevention system 50 enters the unlocked state. The front sensor 511 and the rear sensor 512 can also be other types of sensors, which are not listed here.

[0091] Referring to FIGS. 27 and 28, in an embodiment of the present application, the seat posture adjustment assembly 20 further comprises a reclining angle adjustment mechanism 200. The reclining angle adjustment mechanism 200 comprises a transmission member 230, a slider 220, a driver 260, an operation member 280, and a position detector 2130. Optionally, the position detector 2130 can comprise a first position detector 2131, a second position detector 2132, and a third position detector 2133. The slider 220 has a push rod 132 penetrating through one end thereof, and is drivingly 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 rod. 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 rod. The inner side surface of the slider 220 is provided with a thread, and is capable of moving along the transmission member 230. The movement of the slider 220 along the transmission member 230 is capable of driving the seat body 130 to slide relative to the base 100, so as to change the reclining angle of the seat body 130. The driver 260 is drivingly connected with the transmission member 230, so as to drive the transmission member 230 to move the slider 220. The operation member 280 is provided on the seat body 130, and is used to drive the slider 220 to disengage with the transmission member 230, so as to manually adjust the reclining angle of the seat body 130. Specifically, the slider 220 is connected with the operation member 280 via, for example, a steel wire. When the user pulls the operation member 280, the operation member 280 drives the slider 220 to move away from the transmission member 230 via the steel wire, so as to disengage the slider 220 with the transmission member 230. Thus, the driving connection between the seat body 130 and the driver 260 is released, and the seat body 130 can be manually changed in reclining angle by the user. A plurality of position detectors 2130 are arranged along the extension direction of the transmission member 230, and are electrically connected with the control module 52, and are used to detect the position of the slider 220 relative to the transmission member 230. Exemplarily, the position sensor 405 is an optical sensor. In the embodiment, when the anti-mis-touch system 50 is in standby state or locked state, the user is unable to adjust the reclining angle of the seat body 130 via the input assembly 30. At this time, the user can manually adjust the reclining angle of the seat body 130 via the operation member 280, and the position sensor 405 detects the movement of the slider 220, and outputs a seat posture signal to the control module 52, so as to activate the input assembly 30. When the input assembly 30 is in activated state, the user can quickly control the driver 260 to adjust the reclining angle of the seat body 130 via the function buttons of the input assembly 30, so as to improve the convenience of use.

[0092] In the embodiment shown in FIG. 27, the seat body 130 is provided with a ventilation device 71, which is electrically connected with the control module 52. The ventilation device 71 can be activated or deactivated by pressing the ventilation control button 312 on the input assembly 30. Alternatively, the ventilation control button 312 can also be used to adjust the power of the seat ventilation device 71, for example, by pressing the ventilation control button 312 for a long time or double-clicking the ventilation control button 312 to change the power of the seat ventilation device 71. In the embodiment provided with the ventilation device 71, when the ventilation control button 312 or the seat inclination angle adjustment button 313 is pressed when the external power source is not connected, the display screen 32 displays the "power connection pattern" as shown in FIG. 22b, prompting the user to connect the external power source to enable the seat ventilation function or the seat inclination angle adjustment function.

[0093] The present application also provides a control method for the child safety seat. Referring to FIG. 23b, the control method comprises the following steps:

[0094] When the anti-misoperation system 50 is in the standby state, the seat body 130 of the child safety seat 1 is rotated relative to the base 100 to a preset latching position, for example, a forward position, a rearward position, or a lateral position, and the anti-misoperation system 50 enters the unlocked state. When the anti-misoperation system 50 is in the standby state, the ISOFIX connector reaches a preset plug-in position in the ISOFIX socket, for example, either side of the ISOFIX connector reaches a preset plug-in position in the ISOFIX socket or both sides of the ISOFIX connector reach a preset plug-in position in the ISOFIX socket, and the anti-misoperation system 50 enters the unlocked state. When the anti-misoperation system 50 is in the standby state, the inclination angle of the backrest of the seat body 130 is changed, and the anti-misoperation system 50 enters the unlocked state. When the anti-misoperation system 50 is in the standby state, the power button 311 on the input assembly 30 is pressed, and the anti-misoperation system 50 enters the unlocked state. When the anti-misoperation system 50 is in the standby state, the external power source is plugged into the power interface 101, and the anti-misoperation system 50 enters the unlocked state.

[0095] Alternatively, when the anti-misoperation system 50 is in the unlocked state, if there is no operation (including operating the buttons, adjusting the inclination angle of the backrest, adjusting the rotation position of the seat body 130, and latching the ISOFIX plug connector) on the child safety seat 1 for more than a first predetermined time (for example, 5S, 10S, etc.), the anti-misoperation system 50 changes to the locked state. Referring to FIG. 20b, when the anti-misoperation system 50 changes to the locked state, the first display area 321 of the display screen 32 briefly displays the "button locking pattern".

[0096] Optionally, when the anti-mis-touch system 50 is in the locked state and the time of no operation of the keys is greater than a second predetermined time (e.g., 5 minutes, 10 minutes, etc.), the anti-mis-touch system 50 switches to the standby state.

[0097] Optionally, when the anti-mis-touch system 50 is in the locked state and the time interval of pressing at least two different keys is shorter than a third preset time (e.g., 0.5S, 1S, etc.), the anti-mis-touch system 50 switches to the unlocked state. Referring to FIG. 20a, the right part of the first display area 321 of the display screen 32 displays a "key lock pattern", indicating that the anti-mis-touch system 50 is in the locked state at this time. The left part of the first display area 321 of the display screen 32 provides a prompt to the user that the input assembly 30 can be activated by first clicking the power key 311 and then clicking the ventilation control key 312, so that the anti-mis-touch system 50 switches to the unlocked state. After switching to the unlocked state, the first display area 321 of the display screen 32 briefly displays a "key unlock pattern" as shown in FIG. 20c.

[0098] The technical features of the above-described embodiments can be combined in any manner. For the sake of brevity, not all possible combinations of the technical features in the above-described embodiments are described, however, as long as the combinations of the technical features do not result in contradictions, they shall be considered as within the scope of the present disclosure.
