Detailed Implementation

[0047] The technical solutions in the embodiments (or "implementations") of this application will be clearly and completely described herein with reference to the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements.

[0048] If the embodiments of this application contain terms relating to directional indications or positional relationships (such as up, down, left, right, front, back, inside, outside, top, bottom, center, vertical, horizontal, longitudinal, transverse, length, width, counterclockwise, clockwise, axial, radial, circumferential, etc.), such terms are only used to explain the relative positional relationships and movements between components in a specific posture (as shown in the attached figures); if the specific posture changes, the directional indications or positional relationships will also change accordingly. Furthermore, the terms "first" and "second" used in the embodiments of this application are only for descriptive convenience and should not be construed as indicating or implying relative importance.

[0049] like Figures 1 to 4 As shown, the child seat of this application includes an upper backrest 1, a lower base 2, an adjustment assembly 3, a first sensor 4, and a second sensor 5. The upper backrest 1 is disposed on the adjustment assembly 3 and can slide relative to the adjustment assembly 3. The adjustment assembly 3 is rotatably disposed on the lower base 2, and the upper backrest 1 can slide and rotate relative to the lower base 2 through the adjustment assembly 3. This configuration allows the child seat to be adjusted at multiple angles and in multiple directions, thereby enabling the child seat to have multiple seating positions, improving the applicability of the child seat to children of different age groups.

[0050] In one embodiment, the upper seat back 1 includes a seat belt 11 and a seat back body 12. The seat belt 11 is disposed on the seat back body 12, and the seat back body 12 is disposed on the adjustment assembly 3. The lower base 2 includes a base body 21, a mounting member 22, and a support leg 23. The adjustment assembly 3 is disposed on the base body 21, and the base body 21 is adjustablely fitted onto the mounting member 22, which is used to connect to the vehicle seat. With this configuration, by adjusting the position between the base body 21 and the mounting member 22, the distance between the child seat and the vehicle seat can be changed, making the child seat more securely connected to the vehicle seat.

[0051] Mounting component 22 is equipped with an ISOFIX (Child Safety Seat Fixation System) part 221, which connects to the vehicle seat. The ISOFIX part 221 improves the convenience and safety of connecting the child seat to the vehicle seat.

[0052] The support leg 23 is rotatably connected to the base body 21 and is located at the front end of the base body 21. The support leg 23 is telescopically oriented so that when the child seat is installed, the support leg 23 can contact the vehicle floor, thereby supporting the base body 21 and improving the stability of the child seat after installation.

[0053] Further integration Figures 5 to 6 As shown, in one embodiment, the child seat includes a seating position and an alarm position. The seating position includes a forward-facing state and a rearward-facing state. Further, the base body 21 includes a connecting seat 211 and an extended backrest 212 protruding from the connecting seat 211. The backrest body 12 is disposed on the connecting seat 211 via an adjustment assembly 3. When the upper backrest 1 is away from the extended backrest 212 and faces the front end of the base body 21, the child seat is in the forward-facing state. When the upper backrest 1 faces the extended backrest 212 and faces the rear end of the base body 21, the child seat is in the rearward-facing state. It is worth noting that regardless of whether the child seat is in the forward-facing or rearward-facing state, the upper backrest 1 can be slidably adjusted relative to the lower base 2.

[0054] During the process of the child seat moving from a forward-facing position to a rear-facing position or vice versa, the upper backrest 1 rotates 180 degrees relative to the lower base 2. Each position of the child seat during this process is an alarm position.

[0055] Further integration Figures 7 to 8As shown, in one embodiment, the adjustment component 3 includes a component body 31 and an indicator area 32. The component body 31 is connected between the upper seat back 1 and the lower base 2, and the indicator area 32 is disposed on the component body 31. Furthermore, the indicator area 32 is located on the side of the component body 31 facing away from the upper seat back 1 and towards the lower base 2. The color of the indicator area 32 is different from the color of the component body 31. This configuration improves the accuracy of detecting the indicator area 32, thereby allowing for more accurate confirmation of the child seat's status and more timely warnings.

[0056] Both the first sensor 4 and the second sensor 5 can be used to sense the color of the component body 31 and the indicator area 32. When either the first sensor 4 or the second sensor 5 corresponds to the indicator area 32, the child seat is in a sitting position. Specifically, when the first sensor 4 corresponds to the indicator area 32 and the second sensor 5 corresponds to the component body 31, the child seat is in a forward-facing position. When the second sensor 5 corresponds to the indicator area 32 and the first sensor 4 corresponds to the component body 31, the child seat is in a rear-facing position.

[0057] In another embodiment, when the first sensor 4 corresponds to the indicator area 32 and the second sensor 5 corresponds to the component body 31, the child seat is in a rear-facing state. When the second sensor 5 corresponds to the indicator area 32 and the first sensor 4 corresponds to the component body 31, the child seat is in a forward-facing state.

[0058] In one embodiment, the child seat is in an alarm position when both the first sensor 4 and the second sensor 5 correspond to the component body 31. That is, during the rotation of the child seat from a forward position to a backward position or from a backward position to a forward position, if the upper backrest 1 does not rotate completely relative to the lower base 2, both the first sensor 4 and the second sensor 5 will correspond to the component body 31, thereby triggering an alarm for the child seat being in an incorrect alarm position.

[0059] To improve the detection accuracy of the first sensor 4 and the second sensor 5, the component body 31 and the indicator area 32 are made of colors with a significant color difference. Preferably, the component body 31 is black and the indicator area 32 is white. Alternatively, the component body 31 is white and the indicator area 32 is black. Of course, the component body 31 can also be other darker colors and the indicator area 32 can be other lighter colors; or the component body 31 can also be other lighter colors and the indicator area 32 can be other darker colors.

[0060] In one embodiment, the component body 31 includes a base plate 311 and a guide rail 312. The base plate 311 is rotatably connected to the lower base 2, the upper backrest 1 is slidably disposed on the guide rail 312, and the indicator area 32 is located on the base plate 311. The guide rail 312 is fixed to the base plate 311, and a portion of the guide rail 312 passes through the base plate 311. The guide rail 312 is provided with a guide groove 3121, and the guide groove 3121 is arc-shaped, with the upper backrest 1 connected to the guide groove 3121. The upper backrest 1 can slide relative to the lower base 2 along an arc-shaped trajectory through the guide groove 3121. Preferably, two guide rails 312 are provided, and they are symmetrically disposed on the base plate 311.

[0061] To improve the accuracy of detection by the first sensor 4 and the second sensor 5, the colors of the base plate 311 and the guide rail 312 are different from the color of the indicator area 32. The color of the indicator area 32 is white, and the color of the base plate 311 is the same as the color of the guide rail 312, which is black; or the color of the indicator area 32 is black, and the color of the base plate 311 and the color of the guide rail 312 are white.

[0062] In another embodiment, the color of the base plate 311 and the color of the guide rail 312 may also be different colors with similar hues, and both are significantly different from the color of the indicator area 32.

[0063] In one embodiment, the indicator area 32 includes a first indicator area 321 and a second indicator area 322. To improve the detection accuracy of the first sensor 4 and the second sensor 5, the first indicator area 321 and the second indicator area 322 are disposed on the base plate 311 and spaced apart from each other, and are also located between the two guide rails 312. Furthermore, the first indicator area 321 and the second indicator area 322 are arranged diagonally on the base plate 311. Since the first sensor 4 and the second sensor 5 are mounted in different positions, to make the first indicator area 321 and the second indicator area 322 easier to detect, the first indicator area 321 is closer to the center of the base plate 311 than the second indicator area 322.

[0064] The first indicator area 321 and the second indicator area 322 are the same color, while the base plate 311 and the guide rail 312 are different in color from either the first indicator area 321 or the second indicator area 322. Alternatively, the first indicator area 321 and the second indicator area 322 are white, and the base plate 311 is the same color as the guide rail 312, but is black. Or, the first indicator area 321 and the second indicator area 322 are black, and the base plate 311 and the guide rail 312 are white.

[0065] When the first sensor 4 corresponds to the first indicator area 321, the child seat is in a forward-facing position. When the second sensor 5 corresponds to the second indicator area 322, the child seat is in a rear-facing position. Further, when the child seat is in a forward-facing position, the first sensor 4 corresponds to the first indicator area 321, and the second sensor 5 corresponds to the guide rail 312 or the base plate 311. When the child seat is in a rear-facing position, the second sensor 5 corresponds to the second indicator area 322, and the first sensor 4 corresponds to the guide rail 312 or the base plate 311.

[0066] In another embodiment, when the first sensor 4 corresponds to the first indicator area 321, the child seat is in a rear-facing state. When the second sensor 5 corresponds to the second indicator area 322, the child seat is in a forward-facing state. Further, when the child seat is in a rear-facing state, the first sensor 4 corresponds to the first indicator area 321, and the second sensor 5 corresponds to the guide rail 312 or the base plate 311. When the child seat is in a forward-facing state, the second sensor 5 corresponds to the second indicator area 322, and the first sensor 4 corresponds to the guide rail 312 or the base plate 311.

[0067] In one embodiment, the first sensor 4 and the second sensor 5 are disposed on the lower base 2, and to prevent mutual interference between the first sensor 4 and the second sensor 5, the first sensor 4 and the second sensor 5 are spaced apart. The first sensor 4 and the second sensor 5 are preferably infrared sensors.

[0068] Further integration Figure 9 As shown, in one embodiment, the child seat includes a pressure sensor 6, a time module (not shown), a processor 7, and a reminder module (not shown). The pressure sensor 6, time module, and reminder module are all electrically connected to the processor 7 to receive signals from the pressure sensor 6 and the time module. The processor 7 can control the reminder module to be activated and operational.

[0069] Pressure sensor 6 is located at the bottom of the upper seat back 1 and can be used to sense whether the child seat is occupied and to detect the occupant's weight. The time module records the occupant's birth date and the current time. The time module can record multiple sets of birth date data, allowing the child seat to be reused.

[0070] The first sensor 4 and the second sensor 5 are also electrically connected to the processor 7, and the processor 7 is used to receive signals from the first sensor 4 and the second sensor 5 to control the activation of the reminder module. The reminder module includes a voice module and / or a wireless connection module. The wireless connection module can connect to mobile terminals such as vehicle infotainment systems, mobile phones, and computers. The reminder module can provide reminder notifications via voice, text, images, videos, etc. The reminder module is located on the upper seat back 1 and / or the lower base 2. Alternatively, the reminder module could also be a buzzer, located on the processor 7.

[0071] In one embodiment, the first sensor 4 and the second sensor 5 are fixed to the processor 7 and are located at opposite ends of the processor 7. The processor 7 is disposed on the lower base 2 and is located between the lower base 2 and the base plate 311. In the vertical direction of the child seat, the first sensor 4 and the second sensor 5 are disposed opposite to the first indicator area 321 and the second indicator area 322.

[0072] In this child seat application, when the pressure sensor 6 senses the seating pressure, it sends this signal to the processor 7, which then activates the first sensor 4 and the second sensor 5 for detection. If an abnormal position of the child seat is detected, an alert will be issued via the reminder module. Whether the seat belt is properly engaged, whether the mounting bracket 22 is properly secured, and whether the support leg 23 is properly extended are all within the detection range of the child seat.

[0073] This application's child seat incorporates an adjustment component 3, allowing the upper backrest 1 to rotate relative to the lower base 2, thus enabling multiple seating positions and enhancing the seat's versatility. Simultaneously, the inclusion of a first sensor 4 and a second sensor 5 detects the child seat's seating position and triggers an alarm for incorrect seating, improving safety. Furthermore, the first and second sensors 4 and 5 detect the component body 31 and the indicator area 32, with the latter being different colors, enhancing the accuracy of detection and providing more timely warnings for the child seat.

[0074] Further integration Figures 10 to 11 As shown, this application also provides a method for determining the usage status of a child car seat, including:

[0075] Step S1: Receive the boarding signal;

[0076] Step S2: Turn on the first sensor 4 and the second sensor 5;

[0077] Step S3: Analyze the color data fed back by the first sensor 4 and the second sensor 5 to determine whether the child seat is in a sitting position; if not, activate the reminder module.

[0078] The seating signal is the seating pressure sensed by pressure sensor 6. The seat usage status determination method automatically confirms the passenger's age based on the date of birth recorded by the time module and the current time, and simultaneously combines this with the passenger's weight to automatically match the correct seat position. If the child seat's current position does not conform to the correct seating position, the reminder module will activate and sound an alarm. If the child seat's current position conforms to the correct seating position, the child seat remains in a silent state. Alternatively, the reminder module can also be used to remind the passenger that the seating position is correct.

[0079] In one embodiment, step S3 further includes: analyzing the information fed back by the pressure sensor 6 and the data fed back by the time module to determine whether the child seat is in the correct sitting position; if not, activating the reminder module.

[0080] In one embodiment, to improve the protection provided by the child seat to the occupant, the child seat is positioned rear-facing for occupants under N months old and forward-facing for occupants older than N months. Specifically, the preferred value of N is 12, meaning the child seat is rear-facing for occupants under 12 months old and forward-facing for occupants older than 12 months. Of course, the value of N can also be 8 or 14, etc., and this is not a limitation herein.

[0081] Step S3 also includes: determining whether the passenger's age is within N months;

[0082] If yes, determine whether the second sensor 5 corresponds to the second indicator area 322; if no, activate the reminder module.

[0083] If the passenger's age is determined to be more than N months, determine whether the first sensor 4 corresponds to the first indicator area 321; if not, activate the reminder module.

[0084] In another embodiment, when the first sensor 4 corresponds to the first indication area 321, the child seat is in the rearward state; when the second sensor 5 corresponds to the second indication area 322, the child seat is in the forward state.

[0085] Step S3 includes: determining whether the passenger's age is within N months;

[0086] If yes, determine whether the first sensor 4 corresponds to the first indication area 321; if no, activate the reminder module.

[0087] If the passenger's age is determined to be more than N months, determine whether the second sensor 5 corresponds to the second indicator area 322; if not, activate the reminder module.

[0088] In one embodiment, step S3 further includes: determining whether the mounting component 22 is installed in place; if not, activating the reminder module; determining whether the support leg 23 is extended in place; if not, activating the reminder module; determining whether the seat belt 11 is engaged in place; if not, activating the reminder module.

[0089] In one embodiment, step S3 further includes: activating the voice module to play voice messages; and / or activating the wireless connection module to provide reminders via a mobile terminal.

[0090] The seat usage status determination method of this application, by combining the detection of the occupant's age and weight, can more accurately match the seat position suitable for the occupant, thereby improving the safety of the child seat. Furthermore, by using the first sensor 4 and the second sensor 5 to detect the component body 31 and the indicator area 32, the accuracy of the detection by the first sensor 4 and the second sensor 5 can be further improved, resulting in more timely warnings for the child seat.

[0091] This application also provides a storage medium on which a computer program is stored, and the storage medium can be read by a computer. When the computer program is executed by a processor, it implements the seat usage status determination method as described above.

[0092] It should be noted that the technical solutions or features described in the above embodiments can be combined or supplemented with each other without conflict. The scope of protection of this application is not limited to the precise structures described in the above embodiments and shown in the accompanying drawings; all modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
