[0048] The embodiments of this application will be described in further detail below with reference to the accompanying drawings and examples. The detailed description of the following embodiments and the accompanying drawings are used to illustrate the principles of this application by way of example, but should not be used to limit the scope of this application, that is, this application is not limited to the described embodiments.

[0050] In this application, the reference to "embodiment" means that a specific feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of this application. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a mutually exclusive, independent, or alternative embodiment. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described in this application can be combined with other embodiments.

[0051] In the description of this application, it should also be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this application depending on the specific circumstances.

[0052] In this application, the vehicle can be an internal combustion engine vehicle or an electric vehicle, and is not limited thereto. For example, the vehicle in this application can be an electric vehicle. The vehicle includes a passenger compartment and vehicle seats disposed within the passenger compartment.

[0053] As described in the background section, while car seats in related technologies have seen significant improvements in comfort and functionality, existing car seats lack vital sign detection capabilities. This prevents the car seat from detecting the user's vital signs and obtaining data on the user's physiological characteristics.

[0054] Based on the aforementioned problems, this application provides a car seat. The car seat includes a vital signs sensor. The vital signs sensor includes a housing, a vital signs detection unit, and a first actuator. The first actuator is used to drive the vital signs detection unit to move. A position adjustment component is used to adjust the position of the vital signs detection unit so that it reaches the user's neck skin and can directly contact the neck skin, thereby acquiring the user's human physiological characteristic index data through the vital signs detection unit. Therefore, the car seat of this application can perform physiological characteristic detection after direct contact with human skin, providing highly accurate human physiological characteristic index data for subsequent user health monitoring.

[0055] The following is combined with Figures 1 to 8 The embodiments shown herein describe the car seat, the car, and the vital sign detection method based on the car seat.

[0056] See Figures 1 to 4 As shown, the car seat 100 of this application includes a seat 10, a backrest 20, and a vital signs sensor 30. The backrest 20 is connected to the seat 10. The backrest 20 includes a backrest 21 and a headrest 22. The seat 10 can be used to support the user's weight and provide support for the user's body. The backrest 21 of the backrest 20 can provide effective support for the user's waist and back. The headrest 22 of the backrest 20 can provide effective support for the user's head. When the user sits in the car seat 100, the user's neck can correspond to the area between the backrest 21 and the headrest 22.

[0057] A vital signs sensor 30 is disposed between the backrest 21 and the headrest 22. The vital signs sensor 30 is located on the side of the backrest 20 facing the seat 10. When the user is using the car seat 100, the vital signs sensor 30 faces the user's neck. The vital signs sensor 30 can detect the user's neck to obtain corresponding human physiological characteristic data, thereby realizing the function of the car seat 100 in detecting human physiological characteristics.

[0058] The vital signs sensor 30 includes a housing 31, a vital signs detection unit 32, and a first actuator 33. The housing 31 includes a receiving cavity 31b with an opening 31a. When the user is using the car seat 100, the opening 31a of the receiving cavity 31b can face the user's neck. Both the vital signs detection unit 32 and the first actuator 33 are disposed in the receiving cavity 31b. The vital signs detection unit 32 is positioned corresponding to the opening 31a. The vital signs detection unit 32 includes a support body 321, a position adjustment component 322, and a vital signs detection component 323. The support body 321 is slidably connected to the housing 31. The first actuator 33 is connected to the support body 321. The first actuator 33 is used to drive the vital signs detection unit 32 to move out of or back into the opening 31a of the receiving cavity 31b. The position adjustment component 322 is disposed on the support body 321. The vital signs detection component 323 is disposed on the position adjustment component 322. The position adjustment component 322 is used to adjust the position of the vital signs detection component 323 so that the vital signs detection component 323 is closer to or further away from the support body 321.

[0059] In some examples, after a user sits in the car seat 100, the vital signs sensor 30 can activate the detection mode. The first actuator 33 can drive the vital signs detection unit 32 to move out of the opening 31a of the receiving cavity 31b. Then, the position adjustment assembly 322 adjusts the position of the vital signs detection assembly 323 so that the vital signs detection assembly 323 is away from the carrier body 321, thereby allowing the vital signs detection assembly 323 to reach the user's neck. After the vital signs detection assembly 323 comes into direct contact with the skin area to be detected on the user's neck, the vital signs detection assembly 323 can detect and obtain the corresponding human physiological characteristic index data.

[0060] The automotive seat 100 of this application includes a seat 10, a backrest 20, and a vital signs sensor 30. The vital signs sensor 30 includes a housing 31, a vital signs detection unit 32, and a first actuator 33. By arranging the vital signs detection unit 32 within the receiving cavity 31b of the housing 31, a standardized component structure design can be achieved, facilitating the insertion and removal of the vital signs detection unit 32 from the receiving cavity 31b of the housing 31, and enabling flexible replacement of the vital signs detection unit 32. The vital signs detection unit 32 includes a supporting body 321, a position adjustment component 322, and a vital signs detection component 323. The vital signs detection component 323 can be used to acquire human physiological characteristic index data to provide highly accurate data information for subsequent user health assessment. The position adjustment component 322 can be used to adjust the position of the vital signs detection component 323. The position adjustment component 322 can drive the vital sign detection component 323 to move along a predetermined movement trajectory, and ensure that the vital sign detection component 323 finally achieves good contact with the skin area to be detected, thereby enabling the car seat 100 to perform vital sign detection on the user in a direct contact with the skin, effectively improving the accuracy of the detection data.

[0061] In some embodiments, see Figure 5 As shown, the first actuator 33 includes a telescopic mechanism 331. The housing 31 has a guide rail 311. The carrier body 321 is slidably connected to the guide rail 311. The carrier body 321 is connected to the telescopic mechanism 331. The telescopic mechanism 331 is located on the side of the carrier body 321 facing away from the opening 31a of the receiving cavity 31b.

[0062] In some examples, when the car seat 100 is unoccupied, the telescopic mechanism 331 is in a retracted state. When a user sits on the car seat 100, the telescopic mechanism 331 can change from the retracted state to the extended state, thereby causing the support body 321 to move along the direction of the support body 321 toward the opening 31a, and ultimately causing the support body 321 to move out of the opening 31a of the receiving cavity 31b. Exemplarily, the first actuator 33 can be a hydraulic cylinder or an electric cylinder.

[0063] After completing the vital signs detection, the telescopic mechanism 331 can change from the extended state to the retracted state, thereby driving the carrier body 321 back into the housing 31.

[0064] In some embodiments, see Figure 4 As shown, the position adjustment assembly 322 includes a linkage mechanism 3221. One end of the linkage mechanism 3221 is connected to the support body 321, and the other end is connected to the vital sign detection assembly 323.

[0065] In some examples, the linkage mechanism 3221 is initially in a retracted state. When the carrier body 321 moves out of the opening 31a of the receiving cavity 31b, the linkage mechanism 3221 can change from the retracted state to the extended state to adjust the position of the vital sign detection component 323. This allows the vital sign detection component 323 to reach the skin area to be detected on the user's neck and to fit against the skin area to be detected, thus enabling contact-based vital sign detection.

[0066] After the vital signs detection is completed, the linkage mechanism 3221 can change from the extended state to the retracted state so that the position adjustment component 322 and the vital signs detection component 323 can return to their initial state.

[0067] In some embodiments, see Figure 6 As shown, the vital sign detection component 323 includes a base 3231 and a detection device 3232. The base 3231 is hinged to a linkage mechanism 3221, allowing the base 3231 to rotate relative to the linkage mechanism 3221. The detection device 3232 is located on the side of the base 3231 facing away from the linkage mechanism 3221.

[0068] In some examples, after the carrier body 321 moves out of the opening 31a of the receiving cavity 31b, the linkage mechanism 3221 can change from a retracted state to an extended state, driving the base 3231 to move and adjust its position so that the detection device 3232 can reach the skin area to be detected on the user's neck. Since the base 3231 can rotate relative to the linkage mechanism 3221, when the linkage mechanism 3221 applies a force to the base 3231, the base 3231 can adjust its own position to ensure that the detection device 3232 is in good contact with the skin area to be detected. This helps to avoid gaps between the detection device 3232 and the skin area to be detected, which could allow external light to enter the gaps and affect the detection.

[0069] For example, the base 3231 is provided with a ball socket. One end of the linkage mechanism 3221 is provided with a ball head. The ball head is correspondingly provided with the ball socket. The ball head can be inserted into the ball socket. The base 3231 can rotate around the ball head, so that the detection device 3232 can fit better against the skin when it reaches the user's neck position.

[0070] For example, the base 3231 and the linkage 3221 can be connected by a two-point hinge. The base 3231 is provided with two ball sockets, while one end of the linkage 3221 is provided with two ball heads. The base 3231 can swing relative to the linkage 3221.

[0071] In some embodiments, see Figure 6 As shown, the detection device 3232 includes a detection wave generator 32321, a detection wave receiver 32322, and a temperature detector 32323. The detection wave generator 32321 and the detection wave receiver 32322 are spaced apart. The temperature detector 32323 is located between the detection wave generator 32321 and the detection wave receiver 32322.

[0072] In some examples, the detection wave generator 32321 and the detection wave receiver 32322 can be detection components for detecting a user's vital signs. The detection wave generator 32321 and the detection wave receiver 32322 can be detection components for detecting a user's vital signs based on photovolume change mapping. The detection wave generator 32321 and the detection wave receiver 32322 can be used to detect physiological indicators such as heart rate. The temperature detector 32323 can be used to detect physiological indicators such as body temperature.

[0073] For example, the detection wave generator 32321 can emit light towards the user's skin. Part of the light is absorbed by the user's skin, and another part is reflected by the user's skin. The reflected portion of the light is received by the detection wave receiver 32322. By analyzing the reflected portion of the light, the user's vital signs information can be obtained.

[0074] For example, after the support body 321 moves out of the opening 31a of the receiving cavity 31b, the linkage mechanism 3221 drives the base 3231 to move, so that the detection device 3232 reaches the user's neck position. After the detection device 3232 is in contact with the user's neck skin, the detection wave generator 32321, the detection wave receiver 32322, and the temperature detector 32323 can detect the physiological characteristics of the human body to realize the vital sign detection function of the car seat 100.

[0075] In some embodiments, see Figure 4 As shown, the vital signs sensor 30 also includes a positioning sensor 34. The positioning sensor 34 is disposed on the support body 321. The positioning sensor 34 is disposed corresponding to the opening 31a. The positioning sensor 34 can be used to sense the position of the user's neck to provide neck position information to the central controller, thereby facilitating the position adjustment component 322 to quickly and accurately adjust the position of the vital signs detection component 323 based on the neck position information determined by the positioning sensor 34.

[0076] In some embodiments, see Figure 7 As shown, the vital signs sensor 30 also includes a rotary actuator 35. The rotary actuator 35 is disposed on the support body 321. The positioning sensor 34 is disposed on the rotary actuator 35. The rotary actuator 35 is used to drive the positioning sensor 34 to rotate, thereby enabling the positioning sensor 34 to perform detection and positioning over a wider coverage area.

[0077] In some embodiments, see Figure 7 As shown, the rotary actuator 35 includes a first bracket 351, a second actuator 352, a second bracket 353, and a third actuator 354. The second bracket 353 is rotatably connected to the first bracket 351. The rotation axis of the first bracket 351 is perpendicular to the rotation axis of the second bracket 353. The first bracket 351 is connected to the second actuator 352. The second actuator 352 drives the first bracket 351 to rotate. The second bracket 353 is connected to the third actuator 354. The third actuator 354 drives the second bracket 353 to rotate. The second bracket 353 includes a hemispherical mounting base 3531. A positioning sensor 34 is disposed on the hemispherical mounting base 3531.

[0078] In some examples, the first bracket 351 and the second actuator 352 can be driven by gears. The second bracket 353 and the third actuator 354 can also be driven by gears. The hemispherical mount 3531 drives the positioning sensor 34 to rotate, enabling the positioning sensor 34 to perform detection and positioning over a wider coverage area.

[0079] In some embodiments, see Figure 5As shown, the vital signs sensor 30 also includes a door panel 36. The door panel 36 is rotatably connected to the housing 31. The door panel 36 is disposed corresponding to the opening 31a of the receiving cavity 31b. The door panel 36 can rotate relative to the housing 31 to close or open the opening 31a of the receiving cavity 31b.

[0080] In some examples, after a user sits in the car seat 100, the door panel 36 rotates relative to the housing 31 to open the opening 31a, and the first actuator 33 drives the vital sign detection unit 32 to move out of the opening 31a of the receiving cavity 31b. The position adjustment assembly 322 adjusts the position of the vital sign detection assembly 323 so that the vital sign detection assembly 323 is away from the carrier body 321, thereby allowing the vital sign detection assembly 323 to reach the user's neck position and detect the user's human physiological characteristics.

[0081] This application also provides a car, including the car seat 100 of the above embodiment.

[0082] See Figure 8 As shown, this application also provides a vital sign detection method based on a car seat 100, including:

[0083] Step S100: Provide a car seat 100, which includes a backrest 20 and a vital signs sensor 30. The backrest 20 includes a backrest 21 and a headrest 22. The vital signs sensor 30 is disposed between the backrest 21 and the headrest 22. The vital signs sensor 30 includes a connected position adjustment component 322 and a vital signs detection component 323.

[0084] Step S110: The vital signs sensor 30 detects whether the activation conditions are met. If the activation conditions are met, the vital signs sensor 30 activates the detection mode.

[0085] Step S120: The vital signs sensor 30 identifies the user's neck position;

[0086] Step S130: The vital signs sensor 30 identifies and confirms the skin area to be detected on the user's neck;

[0087] Step S140: The position adjustment component 322 drives the vital sign detection component 323 to move along the predetermined movement trajectory and finally fits into the skin area to be detected;

[0088] Step S150: Vital signs detection component 323 acquires user's human physiological characteristic index data;

[0089] Step S160: The vital signs sensor 30 completes the detection, the position adjustment component 322 drives the vital signs detection component 323 away from the skin area to be detected, and the vital signs sensor 30 returns to its initial position.

[0090] In some examples, in step S110, the activation condition for the vital signs sensor 30 may be that the user triggers a button to activate the vital signs sensor 30. Alternatively, the activation condition for the vital signs sensor 30 may be that the car seat 100 automatically activates it when it detects that the user is sitting on the seat 10.

[0091] For example, a pressure sensor can be installed on the seat 10. The pressure sensor can detect whether the car seat 100 has changed from an unoccupied state to an occupied state. When the car seat 100 is detected to be occupied, the vital signs sensor 30 is activated.

[0092] In some examples, in step S140: when the vital signs sensor 30 comes into contact with the skin area to be detected on the user's neck, it is first determined whether there is light leakage between the vital signs detection component 323 and the user's neck skin. If there is no light leakage between the vital signs detection component 323 and the user's neck skin, it indicates that the vital signs detection component 323 is in good contact with the user's neck skin. The position adjustment component 322 stops working.

[0093] In some examples, after the vital signs detection component 323 acquires human physiological characteristic index data, the position adjustment component 322 moves the vital signs detection component 323 away from the skin area to be detected, and the vital signs sensor 30 returns to its initial position, waiting for the next vital signs detection start command.

[0094] The various embodiments or implementation methods described in this specification are presented in a progressive manner. Each embodiment focuses on the differences from other embodiments, and the same or similar parts between the embodiments can be referred to each other.

Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
