[0036] Embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0037] First, refer to Figure 1 and Figure 2 A vehicle according to an embodiment of the third aspect of the present invention is briefly described. The vehicle can be provided with a seat 10, a vehicle-borne body fat and weight measurement system, a display system and a voice broadcast system. The seat 10 can be integrated into the vehicle-borne body fat and weight measurement system. The display system and the voice broadcast system can be communicatively connected with the vehicle-borne body fat and weight measurement system to form an organic vehicle-borne system architecture. When using the vehicle, the user uses the vehicle-borne body fat and weight measurement system to detect body fat and weight to conveniently obtain physical condition information. The display system and the voice broadcast system can provide intuitive information display or prompts to the user.

[0038] Reference below Figure 1-Figure 4 A seat 10 according to an embodiment of a first aspect of the present invention is described.

[0039] like Figure 1-Figure 4 As shown, the seat 10 according to the first embodiment of the present invention includes: a seat body 11, a footrest 13 and a first body fat detection component 15, the footrest 13 is arranged on the seat body 11; the first body fat detection component 15 is arranged on the footrest 13 to perform body fat detection.

[0040] In this embodiment, the seat 10 is provided with a seat body 11 and a footrest 13. The footrest 13 is provided on the seat body 11. The seat body 11 can provide a seating space for the person to be tested, so that the person to be tested can sit on the seat 10 to meet the use needs of the seat 10. The footrest 13 can be movably provided on the seat body 11 to meet its use needs. The first body fat detection component 15 is provided on the footrest 13 for body fat detection. When the person to be tested is measuring body fat, the footrest 13 can be raised as needed to support the user's lower limbs, that is, the lower limbs of the person to be tested, so that the first body fat detection component 15 can contact the ankle of the person to be tested. The contact with the ankle here refers to the contact with the skin at the ankle position. For example, the first body fat detection component 15 can contact the calf skin near the ankle.

[0041] Illustratively, in this embodiment, bioelectrical impedance analysis is used to measure body fat. The first body fat component can transmit a weak AC signal from the ankle to the body of the person to be measured and receive the AC signal after passing through the human body. The impedance difference is obtained by utilizing the difference in electrical properties of biological tissues and through Ohm's law and frequency domain analysis, and then the body fat content of the human body is obtained in combination with the weight, height and other data of the person to be measured. The structure is simple, the measurement is convenient and fast, and it can be well applied in vehicle-mounted scenarios.

[0042] In this embodiment, the person to be tested can omit the steps of taking off shoes and socks when performing body fat testing, and can quickly and conveniently measure body fat, thereby making it more convenient for the person to be tested to use and providing the person to be tested with a better testing experience.

[0043] In this embodiment, a first body fat detection component 15 is provided on the footrest 13, so that during the body fat detection process of the person to be tested, the first body fat detection component 15 passes through and receives an AC signal through the ankle of the person to be tested. After the current passes through the ankle, it flows along the lower limbs to the upper body and then flows through the whole body better, so that the current can flow through various parts of the body of the person to be tested more comprehensively, so that the detection result can be closer to the actual body fat situation of the person to be tested, and the body fat detection result of the person to be tested is more accurate, so that the detection experience of the person to be tested is better.

[0044] In this embodiment, the first body fat detection component 15 is arranged on the footrest 13, so that when the person to be tested is tested for body fat, the person to be tested sits on the seat 10, and the footrest 13 is raised to support the lower limbs of the person to be tested. The first body fat detection component 15 on the footrest 13 can easily contact the ankle position of the person to be tested, and can save the person to be tested from having to exert force to maintain the position after raising his legs, thereby making the person to be tested more comfortable and relaxed during the test, and providing the person to be tested with a better testing experience.

[0045] According to the chair 10 of the embodiment of the present invention, by providing a seat body 11 and a footrest 13, a first body fat detection component 15 is provided on the footrest 13, so that the person to be tested can sit on the chair 10 and perform body fat detection by contacting the ankles with the first body fat detection component 15. The structure is simple and the layout is reasonable, so that the person to be tested can obtain more accurate body fat detection results and feel more comfortable and relaxed during the body fat measurement process, thereby making the person to be tested have a better detection experience.

[0046] In some embodiments of the present invention, the first body fat detection component 15 includes two groups of first detection electrodes 151 , and the first detection electrodes 151 include first excitation electrodes 1511 and first measurement electrodes 1512 .

[0047] In this embodiment, the first body fat detection component 15 includes two groups of first detection electrodes 151, and the first detection electrodes 151 include first excitation electrodes 1511 and first measurement electrodes 1512. The structure is simple and can well meet the needs of body fat detection. When the person to be tested is undergoing body fat detection, the two groups of first detection electrodes 151 are respectively arranged at the two ankle positions of the person to be tested. Specifically, the footrest 13 can be movably raised to support the legs of the person to be tested. The person to be tested can properly fold and arrange the trouser legs or socks, etc., so that the two ankles are exposed, so that the first excitation electrodes 1511 and the first measurement electrodes 1512 in each group of first detection electrodes 151 can be conveniently in direct contact with the ankles. The operation is simple, and the person to be tested can be well prevented from taking off shoes and socks, etc., making body fat detection more convenient and quick, making it more convenient for the person to be tested during the test, and providing a better user experience.

[0048] In this embodiment, first detection electrodes 151 are set at the two ankles for body fat detection, which can better cover most areas of the body of the person to be tested, so that the person to be tested can obtain more accurate whole body fat data, so that the reference value of the body fat results is higher, and thus the measurement experience of the person to be tested is better. Exemplarily, in this embodiment, body fat measurement is performed by bioelectrical impedance analysis. One of the two first excitation electrodes 1511 applies a weak alternating current to the human body and the other is used for the output of alternating current to form a closed current in the body of the person to be tested. The two first measuring electrodes 1512 detect the voltage, current, etc. in the circuit to obtain impedance data, and then combine the weight data and height, etc. to obtain the body fat data of the person to be tested. Among them, after the current is introduced from the ankle, it will flow along the lower limbs to the upper body and then flow through the whole body better, so that the obtained body fat detection results can better reflect the body fat situation of the whole body, making the body fat results more accurate.

[0049] In one embodiment of the present invention, in the front-to-back direction of the seat 10 (eg Figure 1In the front-to-rear direction shown in FIG. 1 ), the first measuring electrode 1512 is located on a side of the first excitation electrode 1511 away from the seat body 11 .

[0050] The front-to-back direction of the seat 10 may refer to the orientation of the person to be tested when sitting. When the seat 10 is used in a vehicle, the front-to-back direction of the seat 10 may also refer to the front-to-back direction of the vehicle. In this embodiment, the first measuring electrode 1512 is arranged on the side of the first excitation electrode 1511 away from the seat body 11, so that when the first body fat detection component 15 performs body fat detection on the person to be tested, the first measuring electrode 1512 can contact the ankle at a position closer to the distal end of the body, so that the current flow path in the human body is longer to better cover the body area, so that the body of the person to be tested can obtain a more comprehensive and accurate body fat detection, and the body fat detection result is more accurate.

[0051] In one embodiment of the present invention, Figure 1 As shown, the first excitation electrode 1511 and the first measuring electrode 1512 can be raised in an arc shape away from the ankle of the person to be tested. In this way, the first excitation electrode 1511 and the first measuring electrode 1512 can better fit the ankle of the person to be tested, so that the first excitation electrode 1511 and the first measuring electrode 1512 can contact the ankle more stably, so that the body fat detection is more stable and smooth.

[0052] In one embodiment of the present invention, Figure 1 As shown, in the width direction of the seat 10 , two groups of first detection electrodes 151 are symmetrically arranged.

[0053] The width direction of the seat 10 may refer to the lateral direction after the person to be tested sits on it. When the seat 10 is used in a vehicle, the front and rear direction of the seat 10 may also refer to the width direction of the vehicle. In this embodiment, the two groups of first detection electrodes 151 are arranged symmetrically in the width direction of the vehicle, so that the two groups of first detection electrodes 151 can easily cooperate and contact with the two ankles of the person to be tested, so that the person to be tested can be tested in a more comfortable posture. The structure is simple and the layout is reasonable.

[0054] In some embodiments of the present invention, the seat 10 further includes: a support seat 12 and a weight sensor, the support seat 12 is used to support the seat body 11, and the weight sensor is arranged on the support seat 12 for detecting body weight.

[0055] The chair 10 is provided with a support seat 12, which is used to support the chair body 11. The structure is simple, so that the chair 10 can stably carry the person to be tested. When the person to be tested sits on the chair body 11, the weight of the seat body 11 and most or all of the weight of the person to be tested are transferred to the ground or other layout surface through the support seat 12, so that the chair 10 can stably support and carry the person to be tested.

[0056] In this embodiment, a weight sensor is provided to detect the weight of the person to be tested. The weight sensor is provided on the support seat 12 so that the person to be tested can conveniently perform weight detection after sitting on the seat body 11 .

[0057] In this embodiment, the weight sensor is arranged on the support seat 12. After the person to be tested sits on the seat body 11, the weight of the person to be tested, the seat body 11 and the footrest 13 is completely transferred to the ground and other layout surfaces of the seat 10 through the support seat 12. The weight sensor can conveniently perform a complete measurement of the weight of the person to be tested, so that the measured weight data is more accurate, and can well avoid the influence of different postures of the person to be tested on the weight measurement. The person to be tested can flexibly adjust the sitting posture according to personal needs during weight measurement, so that the person to be tested is more convenient and comfortable when measuring weight, and the detection and use experience of the seat 10 is better.

[0058] In one embodiment of the present invention, the support seat 12 includes: a seat 10 bracket and a guide rail 122, the seat 10 bracket and the guide rail 122 are slidingly matched, the seat body 11 is fixedly connected to the seat 10 bracket, and the weight sensor is arranged on the guide rail 122 and / or the seat 10 bracket.

[0059] In this embodiment, the support seat 12 is provided with a seat bracket 121 and a guide rail 122. The guide rail 122 can be contacted or fixed on a layout surface such as the ground as needed. The seat bracket 121 and the guide rail 122 are slidably matched with each other, and the structure is simple, so that the seat body 11 can be displaced in the front and rear directions, so that the person to be tested can use the seat 10 more flexibly and conveniently. For example, when the seat 10 is used in a vehicle, the guide rail 122 can be fixed on the floor of the vehicle, and the person to be tested can easily adjust the position of the seat 10, making the person to be tested more comfortable.

[0060] In this embodiment, the weight sensor is arranged on the seat 10 bracket and / or the guide rail 122. For example, the weight sensor can be arranged on the seat 10 bracket, or the weight sensor can be arranged at the position where the guide rail 122 contacts the layout surface, or the seat 10 bracket and the position of the noble and layout surface are provided with weight sensors, so that the weight sensor can detect the weight of the seat body 11 and the support seat 12 as a whole, so that the weight sensor can also measure the weight of the person to be measured more accurately, making the weight measurement result of the person to be measured more accurate.

[0061] When the weight sensor is arranged on the seat support 121 and the guide rail 122, the weight sensor on the seat support 121 can cooperate with the weight sensor on the guide rail 122 to more accurately detect the weight of the person to be measured, so that the weight measurement result of the person to be measured is more accurate and the user experience of the person to be measured is better. The arrangement of the weight sensor on the support seat 12 can be reasonably set as needed.

[0062] In one embodiment of the present invention, Figure 1 As shown, the seat support 121 may include a plurality of legs, the plurality of legs are arranged at intervals, the plurality of legs are fixedly connected to the seat body 11, and a weight sensor is disposed on each leg.

[0063] In this embodiment, the seat support is provided with a plurality of legs fixedly connected to the seat body 11, so that the seat support 121 can support the seat body 11 more stably and reliably. A weight sensor is provided on each leg, so that the plurality of weight sensors can cooperate to detect the total weight transferred from the seat body to the seat support 121, so that the weight of the person to be tested can be detected more accurately and reliably, and the measurement result can be more accurate, so that the user experience of the person to be tested is better. For example, the legs can be provided with two, three, four, etc., and the number of legs can be reasonably set according to the setting requirements of the seat 10, and the number of weight sensors is set in a one-to-one correspondence with the number of legs. Optionally, the weight sensor can be a resistive strain gauge.

[0064] In one embodiment of the present invention, Figure 1 As shown, the seat 10 may further include a footrest adjuster 14, which may include a mounting bracket, the mounting bracket including a rotating portion and a fixed portion, the fixed portion being fixedly connected to the seat body 11, the rotating portion being rotatably connected to the fixed portion, the rotating portion being provided with a guide member, the guide member extending in a direction perpendicular to the rotation axis of the rotating portion, the footrest 13 being suitable for slidingly cooperating with the guide member so that the footrest 13 is movable along the extension direction of the guide member.

[0065] In this embodiment, the footrest adjuster 14 is provided with a mounting bracket, the fixed portion of the mounting bracket is fixedly connected to the seat body 11, the rotating portion of the mounting bracket is rotatably connected to the fixed portion, and the rotating portion is provided with a guide member that slides with the footrest 13. The structure is simple, so that the footrest 13 can rotate relative to the seat body 11 and can move away from or close to the seat body 11 along the extension direction of the guide member.

[0066] It can be understood that when the feet of the person to be tested are lifted off the floor, the ankles are in the front-to-back direction and the up-down direction of the vehicle (such as Figure 1In the embodiment of the present invention, the footrest 13 is rotatable relative to the seat body 11 and can be moved away from or close to the seat body 11 along the extension direction of the guide member, so that when the footrest 13 is raised, the footrest 13 can follow the rotation of the rotating part and move away from the seat body 11 in the front and rear direction of the vehicle along the guide member, so that the first body fat detection component 15 on the footrest 13 can be conveniently moved to the ankle position of the person to be tested, so that the person to be tested can stretch more naturally and comfortably under the support of the footrest 13 and have good contact with the first body fat component, so that the person to be tested has a better and more comfortable use experience.

[0067] In some examples of the present invention, the fixed part may be provided with a mating gear, and the foot rest adjuster 14 may also include a driving motor and a driving gear, the driving motor is fixed to the rotating part, the driving gear is connected to the output shaft of the driving motor, and the driving gear is meshed with the mating gear for transmission.

[0068] In this embodiment, a driving motor and a driving gear are provided. The driving motor is fixed on the rotating part and drives the driving gear to rotate. The driving gear meshes with the matching gear on the fixed part for transmission. Therefore, when the driving gear rotates around the matching gear, the rotating part can follow the driving motor to rotate relative to the fixed part, so that the footrest 13 can rotate relative to the seat body 11. The structure is simple and the transmission is stable and reliable, so that the footrest 13 can operate stably and reliably.

[0069] For example, the rotating part and the fixed part can be rotatably connected by a rotating shaft, the rotating part rotates around the axis of the rotating shaft, and the rotating shaft can extend along the seat body 11 in the left and right direction of the vehicle, so that the footrest 13 can gradually lift the legs of the person to be tested and support the lower limbs. Optionally, at least one driving motor can be provided.

[0070] In one example of the present invention, the foot rest 13 may include a face cover and a foot rest frame, the face cover is arranged on the foot rest frame, the first body fat detection component 15 is arranged on the face cover, the foot rest 13 also includes a screw motor, the screw electrode is fixed on the rotating part, the screw motor includes an output screw, the output screw extends along the extension direction of the guide member, the foot rest frame is provided with a matching piece, and the matching piece is matched with the output screw thread of the screw electrode.

[0071] In this embodiment, the footrest 13 is provided with a face cover and a footrest frame, wherein the face cover is mounted on the footrest frame, and has a simple structure and good structural strength, so that the footrest 13 can stably support the lower limbs of the person to be tested, and the face cover can make the part of the person to be tested supported on the footrest 13 more comfortable, thereby making the footrest 13 have a better supporting effect on the person to be tested.

[0072] In this embodiment, the screw motor is fixed on the rotating part, and the output screw of the screw motor is threadedly matched with the matching piece on the footrest frame, so that the footrest 13 can be assembled and fixed to the rotating part of the mounting bracket more stably through the screw and the matching piece. When the footrest 13 is raised, the drive motor and the screw motor can operate at the same time, so that during the process of the footrest 13 rotating around the rotating axis, the footrest 13 can move away from the rotating part under the threaded transmission of the screw motor and the matching piece, so that the footrest 13 can gradually move away from the seat body 11 in the front and rear direction of the vehicle, thereby, after the footrest 13 is raised, the first body fat detection component 15 on the footrest 13 can stably contact the ankle of the person to be tested for body fat detection. Optionally, at least one screw motor can be provided.

[0073] In some specific embodiments of the present invention, the footrest frame may be provided with a connecting rod, the guide member is a guide cylinder, and the connecting rod penetrates into the guide cylinder along the extension direction of the guide member and slides in cooperation with the guide cylinder.

[0074] In this embodiment, a connecting rod is arranged on the footrest frame, and the guide member is arranged as a guide cylinder. The connecting rod and the guide cylinder are slidably matched with each other, and the structure is simple. The matching of the connecting rod and the guide cylinder can play a role in structural reinforcement of the footrest 13 and the mounting bracket. For example, when the footrest 13 supports the lower limbs of the person to be tested, the connecting rod and the guide cylinder can well play a role in connecting and strengthening the footrest 13 and the mounting bracket, so that the weight supported by the footrest 13 can be more stably and reliably transferred to the mounting bracket from the connecting rod and the guide cylinder, the matching member and the screw, so that the footrest 13 can play a supporting role more stably and reliably, and the operation of the footrest 13 can be more stably and reliably.

[0075] The guide member and the guide tube cooperate to guide the movement of the footrest 13 along the extension direction of the guide member, so that the footrest 13 can move away from the seat body 11 more stably and reliably during the rotation around the rotation axis, so that the footrest 13 can operate stably and reliably.

[0076] For example, the number of guide members can be multiple, and the number of guide cylinders can also be multiple, and the multiple guide members are arranged at intervals along the left and right directions of the vehicle on the seat 10, and the guide cylinders are arranged one by one correspondingly. In this way, the overall structural strength of the footrest 13 can be further enhanced, and the structure of the footrest 13 can be more stable and reliable, so that the footrest 13 can be stably and reliably raised and lowered and carry the lower limbs of the person to be tested, so that the seat 10 can operate more stably. Optionally, the number of guide members is two, and the number of guide cylinders is two.

[0079] The vehicle-borne body fat and weight measurement system in this embodiment includes a second body fat detection component 30, which contacts the two hands of the person to be tested to perform body fat detection. It has a simple structure and can perform body fat detection on the upper body of the person to be tested, thereby cooperating with the first body fat detection component 15 to perform a more comprehensive and accurate body fat measurement of the whole body of the person to be tested, so that the body fat detection result can more accurately reflect the body fat status of the person to be tested, so that the person to be tested can take more suitable and reasonable health management measures according to the body fat result, making the vehicle-borne body fat and weight measurement system more practical and providing the person to be tested with a better user experience.

[0080] According to the vehicle-borne body fat weight measurement system of an embodiment of the present invention, by setting the seat 10 of the first aspect embodiment mentioned above, the seat 10 is provided with a seat body 11 and a footrest 13, and the first body fat detection component 15 is arranged on the footrest 13, so that the person to be tested can sit on the seat 10 and perform body fat detection by contacting the first body fat detection component 15 with the ankle. The structure is simple and the layout is reasonable, so that the person to be tested can obtain more accurate body fat detection results and feel more comfortable and relaxed during the body fat measurement process, thereby making the person to be tested have a better detection experience.

[0081] In some embodiments of the present invention, Figure 2 As shown, the second body fat detection component 30 includes two groups of second detection electrodes 31 , and the second detection electrodes 31 include second excitation electrodes 311 and second measurement electrodes 312 .

[0082] In this embodiment, the second body fat detection component 30 includes two groups of second detection electrodes 31, and the second detection electrodes 31 include second excitation electrodes 311 and second measurement electrodes 312. The structure is simple and can well meet the needs of body fat detection. When the person to be tested is undergoing body fat detection, the two groups of second detection electrodes 31 can be respectively arranged at the positions of the hands of the person to be tested and directly contact the hands, and the vehicle-mounted body fat and weight measurement system performs body fat measurement.

[0083] In one embodiment of the present invention, Figure 2 As shown, the vehicle-mounted body fat and weight measurement system may further include a steering wheel 20, a second body fat detection component 30 is disposed on the steering wheel 20, the steering wheel 20 includes a rim 21, a second excitation electrode 311 is disposed on a side of the rim 21 facing away from the seat 10, and a second measuring electrode 312 is disposed on the other side of the rim 21 facing the seat 10.

[0084] In this embodiment, the second body fat detection component 30 is arranged on the steering wheel 20, which has a simple structure and a convenient and reasonable layout. The seat 10 of this embodiment can be a driver's seat. When the person to be tested uses the vehicle-mounted body fat and weight measurement system to perform body fat detection, the person to be tested can conveniently put his hands on the second body fat detection component 30 of the steering wheel 20, so as to cooperate with the first body fat detection component 15 of the foot rest 13 to conveniently perform body fat measurement.

[0085] In this embodiment, the second excitation electrode 311 is arranged on the side of the rim 21 facing away from the seat 10, and the second measuring electrode 312 is arranged on the side of the rim 21 facing the seat 10, so that when the person to be tested grasps the rim 21, the second excitation electrode 311 can more conveniently and easily contact the thumb of the hand, and the second measuring electrode 312 can more conveniently and easily contact the palm, so that the second measuring electrode 312 can be located at the far end of the body away from the second excitation electrode 311 of the hand, so that the flow path of the current in the human body can be longer to better cover the body area, so that the body of the person to be tested can obtain more comprehensive and accurate body fat detection, and the body fat detection result can be more accurate.

[0086] Optionally, the second excitation electrode 311 and the second measuring electrode 312 may be arranged reasonably on the rim 21 as needed, so that the person to be tested can easily contact the second excitation electrode 311 and the second measuring electrode 312 and have a suitable position relationship to improve the detection effect.

[0087] In one example of the present invention, reference Figure 2 As shown, the two groups of second detection electrodes 31 can be respectively arranged on the steering wheel 20 along the left and right directions of the vehicle (such as Figure 2 In this way, the hands of the person to be tested can easily contact the two sets of second detection electrodes 31 when grasping the steering wheel 20, and the arms of the person to be tested can be more easily in a straight state, thereby avoiding the decrease in measurement accuracy caused by bending the arms to a certain extent, making body fat detection more accurate.

[0088] In one example of the present invention, reference Figure 2 As shown, the rim 21 may be provided with a plurality of mounting holes, which are arranged one-to-one with the second excitation electrodes 311 and the second measuring electrodes 312 , the second excitation electrodes 311 and the second measuring electrodes 312 are respectively provided at the openings of the mounting holes, and the second excitation electrodes 311 and the second measuring electrodes 312 both close the mounting holes.

[0089] In this embodiment, a mounting hole is provided on the wheel rim 21 to assemble the second excitation electrode 311 and the second measuring electrode 312. The structure is simple and the arrangement is convenient. The second excitation electrode 311 and the second measuring electrode 312 both close the mounting hole, so that the outer surface of the second excitation electrode 311, the outer surface of the second measuring electrode 312 and the outer surface of the wheel rim 21 cooperate to form a continuous and complete surface, so that the steering wheel 20 can maintain good comfort when in use. Here, the outer surface of the second excitation electrode 311 and the second measuring electrode 312 refers to the surface located at the opening of the mounting hole and leaking out of the opening. Optionally, the outer surface of the second excitation electrode 311 and the second measuring electrode 312 can be formed into an arc surface with a certain curvature to fit the skin of the hand, so that the person to be tested is more comfortable when grasping, and the second excitation electrode 311 and the second measuring electrode 312 can better fit the contact hand.

[0090] Optionally, the opening shape of the mounting hole may be adjusted accordingly according to the shape requirements of the second excitation electrode 311 and the second measurement electrode 312 , so that the second excitation electrode 311 and the second measurement electrode 312 can completely close the opening of the column mounting hole.

[0091] Exemplarily, the skeleton of the steering wheel 20 may be a central control structure, so that the wheel rim 21 may be formed with a cavity, so that the circuit of the second detection component may be arranged in the cavity, thereby making it easier to conveniently wire the steering wheel 20 and the second detection component during assembly and arrangement.

[0092] In some specific embodiments of the present invention, a stabilizing bracket may be provided in the mounting hole, and the second excitation electrode 311 and the second measuring electrode 312 may be fixed on the stabilizing bracket. In this way, the installation and fixing of the second excitation electrode 311 and the second measuring electrode 312 on the wheel rim 21 may be more stable and reliable. Exemplarily, the stabilizing bracket is a plastic part, and the stabilizing bracket may be partially filled between the second excitation electrode and the edge of the mounting hole and between the second measuring electrode 312 and the edge of the mounting hole, so that the second physical fitness detection component is electrically separated from the skeleton structure of the steering wheel 20, thereby meeting the operation requirements of the second body fat detection component 30.

[0093] In some specific embodiments of the present invention, reference Figure 3 As shown, the vehicle-mounted body fat and weight measurement system may further include a control module 40 , which may be communicatively connected with the weight sensor, the first body fat detection component 15 , and the second body fat detection component 30 .

[0094] When the vehicle-borne body fat and weight measurement system is operating, the control module 40 can control the operation of the first body fat detection component 15, the second body fat detection component 30 and the weight sensor and process and analyze the acquired data to obtain the body fat detection result. The control module 40 is communicated with the display system so that the display system can obtain the body fat detection result and store and display it as needed, so that the vehicle-borne body fat and weight measurement system can operate stably and well.

[0095] Exemplarily, the control module 40 may be an operation controller, and the control module 40 may have functions such as AC signal generation, electric signal acquisition, command reception and execution, and data operation processing. The control module 40 may be arranged inside the steering wheel 20 assembly, under the seat 10, or inside the instrument system according to assembly requirements, and the display system may be a vehicle-mounted host.

[0096] Reference below Figure 1-Figure 8 A vehicle according to an embodiment of the third aspect of the present invention is described.

[0097] like Figure 1-Figure 8 As shown, the vehicle according to the embodiment of the present invention comprises: the seat 10 according to the first embodiment of the present invention or the vehicle-borne body fat and weight measuring system according to the second embodiment of the present invention, as well as the display system and the voice broadcast system. The seat 10 comprises a support seat 12, the support seat 12 comprises: a seat 10 bracket and a guide rail 122, the seat 10 bracket and the guide rail 122 are slidably matched, and the guide rail 122 is fixed to the floor of the vehicle; the display system and the voice broadcast system are communicatively connected with the vehicle-borne body fat and weight measuring system.

[0098] In this embodiment, the guide rail 122 of the seat 10 is fixed to the floor of the vehicle, and the structure is simple, so that the seat 10 can be stably and reliably installed in the vehicle. In this embodiment, the display system and the voice broadcast system are connected to the vehicle-borne body fat weight measurement system. When the vehicle-borne body fat weight measurement system is in operation, the display system cooperates with the voice broadcast system to provide the person to be tested with an interactive interface and voice prompts with the vehicle-borne body fat weight measurement system, so that the person to be tested can operate the vehicle-borne body fat weight measurement system as needed. For example, the person to be tested can activate the vehicle-borne body fat weight measurement system, and the person to be tested can establish a personal file to record each body fat weight test result. The display system can record and store personal files, update personal files in a timely manner, and provide health management suggestions or guidance to users based on the changes in body fat weight of the person to be tested in the historical files, etc., so as to meet and improve the user's experience.

[0099] Other components and operations of the vehicle according to the embodiment of the present invention are known to those skilled in the art and will not be described in detail here.

[0100] According to the vehicle of the embodiment of the present invention, by setting the seat 10 of the first embodiment mentioned above or the vehicle-borne body fat weight measurement system according to the second embodiment of the present invention, by setting the seat 10 of the first aspect mentioned above, the seat 10 is provided with a seat body 11 and a footrest 13, and the first body fat detection component 15 is arranged on the footrest 13, so that the person to be tested can sit on the seat 10 and perform body fat detection by contacting the first body fat detection component 15 with the ankle. The structure is simple and the layout is reasonable, so that the person to be tested can obtain more accurate body fat detection results and be more comfortable and relaxed during the body fat measurement process, thereby making the person to be tested have a better detection experience.

[0101] Reference below Figure 1-Figure 8 A method for measuring body fat mass according to an embodiment of the present invention is described.

[0102] like Figure 1-Figure 8 As shown, the body fat and weight measurement method according to an embodiment of the present invention is used in the vehicle-borne body fat and weight measurement system according to the second aspect of the present invention. The body fat and weight measurement method includes: determining that a person to be measured is sitting on the seat 10; obtaining weight data of the person to be measured; determining that the first body fat detection component 15 and the second body fat detection component 30 are in a conducting state; obtaining body fat data of the person to be measured; comparing and analyzing the body fat and weight data, and generating a report.

[0103] In this embodiment, it is determined that there is a person to be tested sitting in the seat 10. The vehicle can make a judgment through the seat belt reminder sensor or the camera vision in the vehicle, thereby ensuring that the vehicle-borne fat weight measurement system can perform the measurement operation when the person to be tested is sitting in the seat 10. Correspondingly, when there is no one in the seat 10, the vehicle-borne fat weight measurement system can remain in standby mode, thereby making the vehicle-borne fat weight measurement system more intelligent and flexible during operation, and operating stably and reliably, and to a certain extent avoiding the impact of the vehicle-borne fat weight measurement system running for no reason on the corresponding person to be tested, which causes a decrease in the user experience, and makes the user experience of the person to be tested better.

[0104] The weight data of the person to be tested is obtained, that is, the vehicle-mounted fat weight measurement system measures the weight of the person to be tested. During this process, the footrest adjuster 14 can control the footrest 13 to rise, so that the legs of the person to be tested are gradually lifted and the feet are off the ground, and the weight sensor measures the weight of the person to be tested. Since the person to be tested needs a certain amount of time to gradually maintain a relatively stable posture during this process, the weight sensor can measure the weight data of the person to be tested in real time. After the weight data gradually stabilizes, a relatively accurate weight result can be obtained, thereby obtaining the weight data of the person to be tested.

[0105] Exemplarily, the footrest adjuster 14 can be adjusted accordingly according to the information of the person to be tested stored in the vehicle-mounted host, so that the footrest 13 is adjusted to a position that can support the ankle of the person to be tested, so that the lower limbs of the person to be tested can be placed on the footrest 13 in a more comfortable posture.

[0106] Exemplarily, the vehicle-borne body fat and weight measurement system can display the measurement results to the person to be tested after obtaining the weight data of the person to be tested. For example, the display system can cooperate with the voice broadcast system to inform the person to be tested of the weight measurement results and prompt the completion of the measurement in the form of a display screen display or speaker broadcast, so as to improve the measurement experience of the person to be tested and facilitate the person to be tested to adjust his posture in time for subsequent body fat measurement.

[0107] Determine that the body fat detection component is in the on state, where the body fat detection component refers to the first body fat detection component 15 and the second body fat detection component 30. For example, when the seat 10 is the driver's seat, when the vehicle-borne body fat and weight measurement system measures the weight of the person to be measured, the hands of the person to be measured need to be separated from the steering wheel 20 to obtain accurate weight data, and there is a situation where the ankles of the person to be measured are covered by clothing. In this embodiment, it is first determined that the body fat detection component is in the on state, that is, the first body fat detection component 15 in the body fat detection component is in contact with the ankle, and the hands of the person to be measured grasp the steering wheel 20 to contact the second body fat detection component 30, so that the body fat detection can be carried out normally and smoothly, and the vehicle-borne body fat and weight measurement system can operate stably.

[0108] After determining that the body fat detection component is in the on state, the first body fat detection component 15 and the second body fat detection component 30 can cooperate to perform body fat detection on the person to be tested, and the control module 40 can process and analyze the measured data in combination with information such as the weight and height of the user to be tested, so as to obtain the body fat data of the person to be tested. The body fat data here may refer to body fat-related data, for example, it may include the total amount of water, fat mass, non-fat mass, etc. of the human body, so as to more comprehensively reflect the body fat condition of the person to be tested, and the fat mass can be based on the weight data.

[0109] Compare and analyze body fat and weight data, generate reports, the vehicle-borne body fat and weight measurement system can cooperate with the display system to store the measured weight and body fat data and form an archive, record the body fat and weight data of the person to be tested for a long time and multiple measurements, and conduct comparative analysis to obtain the changes in the body fat and weight of the person to be tested to form a report. The display system and the voice broadcast system can show the report to the person to be tested, so that the person to be tested can easily and clearly understand the physical condition and physical changes. For example, the display system can also provide reference suggestions related to health management to the person to be tested based on the data information in the personal file, and the display system can also transmit the personal file to the cloud platform so that the person to be tested can view it on the mobile software.

[0110] In some embodiments of the present invention, Figure 6 As shown, before determining that the person to be measured is sitting on the seat 10, the body fat and weight measurement method further includes: determining that the vehicle is in a safe parking state.

[0111] In this embodiment, before determining that the person to be tested is sitting on the seat 10, it is determined that the vehicle is in a safe parking state. It is understandable that during the process of the vehicle-borne body fat and body fat measurement system performing body fat detection, the person to be tested cannot perform manipulation operations such as moving or parking the vehicle, and the feet of the person to be tested are in a suspended state. Therefore, before determining that the person to be tested is sitting on the seat 10, it is determined that the vehicle is in a safe parking state, which can ensure that the vehicle is in a safe external environment during the measurement process, so that the vehicle-borne body fat and body fat measurement system can stably, safely and smoothly perform body fat detection, so that the person to be tested can smoothly and safely perform body fat and body weight measurement. The safe parking state here may include but is not limited to: the gear position of the vehicle is in the parking gear position, the vehicle is not at a position such as an intersection, there are obstacles around the vehicle, there are no vehicles coming from the rear of the vehicle, etc., which meets the conditions for the person to be tested to get on and off the vehicle and the vehicle can be parked for a long time.

[0112] In this embodiment, it is determined that the vehicle is in a safe parking state. For example, the vehicle can make this determination by using the cooperation of the vehicle-mounted host and the control module 40 and other devices as well as a vehicle-mounted camera.

[0113] In this embodiment, after confirming that the vehicle is in a safe parking state, the vehicle-borne fat weight measurement system proceeds to subsequent steps. When the vehicle is not in a safe parking state, the vehicle-borne system measurement system can prompt the person to be tested of the vehicle status. For example, the vehicle-borne host can remind the person to be tested through a display screen or a prompt sound that measurement is currently not possible, so that the person to be tested can adjust the vehicle status in time and control the vehicle to achieve a safe parking state. The vehicle-borne fat weight measurement system proceeds to subsequent steps after detecting that the vehicle is in a safe parking state, so that the vehicle-borne fat weight measurement system can operate more intelligently and flexibly, making it more convenient for the person to be tested to use and having a better user experience.

[0114] For example, the prompt method of the vehicle-mounted host can be reasonably selected according to actual needs. When the vehicle is converted from an unsafe parking state to a safe parking state after the operation of the person to be tested, the person to be tested can manually operate the vehicle-mounted host to make the vehicle-mounted host reconfirm the status of the vehicle, and then perform subsequent weight and body fat detection operations normally, so that the vehicle-mounted body fat and weight measurement system can operate more stably and reliably.

[0115] In some embodiments of the present invention, Figure 7 As shown, before determining that the person to be measured is sitting on the seat 10, the body fat and weight measurement method also includes: confirming that no one is sitting on the seat 10; and resetting the weight sensor.

[0116] In this embodiment, before determining that the person to be tested is seated in the seat 10, it is confirmed that no one is sitting in the seat 10 and the weight sensor is reset to zero, which can facilitate accurate measurement of the weight. It can be understood that the weight sensor actually obtains the total weight of the seat body 11 and the person to be tested or the total weight of the entire seat 10 and the person to be tested. In this embodiment, the weight sensor is reset when no one is sitting in the seat 10, so that the data obtained by the weight sensor is the weight data of the person to be tested, thereby avoiding the influence and interference of the weight change of the seat 10 during long-term use on the weight data, so that the vehicle-borne fat weight measurement system can measure the weight of the person to be tested more accurately.

[0117] Exemplarily, the confirmation that the seat 10 is empty and the zeroing of the weight sensor in this embodiment can be performed as needed before or after the on-board host determines that the vehicle is in a safe parking state. For example, when the person to be tested unlocks the vehicle, the weight sensor can be reset, so that the weight of the person to be tested can be measured when he enters the vehicle and sits on the seat 10 normally. This can achieve the effect of non-contact measurement to a certain extent, avoiding the poor measurement experience caused by the person to be tested entering and exiting the vehicle to perform the zeroing operation or standing up to perform the zeroing operation, making the vehicle-borne fat and weight measurement system more convenient and easy to use.

[0118] In some embodiments of the present invention, reference Figure 8 As shown, before determining that the vehicle is in a safe parking state, it may also include confirming that the vehicle body fat weight measurement system is activated.

[0119] In this embodiment, before determining that the vehicle is in a safe parking state, it is confirmed that the vehicle-borne fat weight measurement system is activated, that is, when the vehicle-borne fat weight measurement system is operating normally, the person to be tested can activate the vehicle-borne fat weight measurement system or deactivate the vehicle-borne fat weight measurement system as needed. When the vehicle-borne fat weight measurement system is in an activated state, the vehicle-borne fat weight measurement system can perform subsequent measurement operations of weight, body fat, etc. to meet the use needs of the person to be tested. When the vehicle-borne fat weight measurement system is in an inactivated state, the vehicle-borne fat weight measurement system can be in a standby state to avoid interfering with the normal use of the vehicle by the person to be tested and save the consumption of system operation, so that the vehicle-borne fat weight measurement system can maintain a stable state to wait for activation by the person to be tested.

[0120] For example, after the vehicle is powered on or unlocked, the vehicle-borne body fat and weight measurement system can perform a self-check to confirm that the system is normal, thereby ensuring that subsequent body fat and weight measurements can be carried out stably and smoothly, or ensuring that after the person to be tested subsequently activates the vehicle-borne body fat and weight measurement system, body fat and weight measurements can be carried out stably, reliably and normally, thereby greatly improving the stability of the vehicle-borne body fat and weight measurement system and, to a certain extent, providing the person to be tested with a better user experience.

[0121] In one embodiment of the present invention, after the person to be tested activates the vehicle-borne fat and weight measuring system, the vehicle-borne fat and weight measuring system enters the initial information of the person to be tested and creates a personal file.

[0122] After the person to be tested activates the vehicle-borne body fat and weight measurement system, the person to be tested can enter personal initial information in the interactive interface of the vehicle-borne host and complete the creation of the file, so that the vehicle-borne body fat and weight measurement system can record the body fat and weight measurement results in the file of the person to be tested, so as to record the body fat and weight changes of the person to be tested, and then provide data reference and comparison for the subsequent health management measures of the person to be tested.

[0123] Exemplarily, the initial information may include, but is not limited to, information on the gender, age, height, etc. of the person to be tested, and the category of the initial information may be reasonably set as needed.

[0124] In one embodiment of the present invention, reference Figure 8 As shown, after the vehicle-mounted fat weight measurement system obtains the weight data, the following steps may also be performed: confirming that the weight data is accurate, selecting or creating a personal profile, and entering the weight data into the personal profile.

[0125] In this embodiment, after the vehicle-borne fat weight measurement system obtains the weight data, the person to be measured can confirm the weight data. When the person to be measured has objections to the weight data, the vehicle-borne fat weight measurement system can measure the weight again to meet the measurement needs of the person to be measured.

[0126] It is understandable that different persons to be tested may drive the same vehicle, and the vehicle-borne body fat and weight measurement system only establishes a personal file for a specific person to be tested when activated. In this embodiment, after confirming that the weight data is accurate, the person to be tested is provided with the operation of selecting or creating a new personal file, which can well meet the need for separate storage and recording of data results after weight and body fat measurement of different persons to be tested, so that the vehicle-borne body fat and weight measurement system can record and save the weight and body fat measurement results of multiple persons to be tested at the same time, thereby meeting the usage needs of the persons to be tested.

[0127] In one embodiment of the present invention, reference Figure 8 As shown, before determining that the body fat detection component is in the on state, it can also include reminding the person to be tested to adjust his posture.

[0128] In this embodiment, before determining that the body fat detection component is in the on state, the person to be tested is reminded to adjust his posture. The display system and the voice broadcast system can cooperate to remind the person to be tested to adjust his posture by means of a picture or a prompt sound or a combination of the two, so that the person to be tested can adjust his posture in time for subsequent body fat detection. For example, the prompt content can be "extend your arms, place your hands on the designated positions of the steering wheel 20, touch the electrodes, place your feet on the footrest 13, and the skin of your ankles touches the electrodes on the footrest 13. Relax your body and keep sitting for body fat measurement", so that the person to be tested can adjust his posture more quickly and accurately, so that the vehicle-mounted body fat and weight measurement system can operate more efficiently and stably.

[0129] In one embodiment of the present invention, reference Figure 8 As shown, after the vehicle-borne body fat and weight measurement system obtains the body fat data of the person to be measured, the body fat data can also be entered into the personal file.

[0130] In this embodiment, after the vehicle-borne fat and weight measurement system obtains the body fat data of the person to be tested, the body fat data is entered into the personal file, so that the person to be tested can obtain more complete physical condition information, and the person to be tested can obtain a complete record reflecting the changes in personal physical condition after long-term and regular body fat and weight measurement, so that the person to be tested can adopt a health management method that is more in line with the personal physical condition based on the personal file, and then the person to be tested can obtain a more significant improvement in physical condition, making the vehicle-borne fat and weight measurement system more practical.

[0131] For example, reference Figure 8 As shown, the personal profile consisting of body fat data and weight data can be presented to the person to be tested in the form of in-vehicle multimedia, for example, by using the display screen of the vehicle's display system and the speaker of the voice broadcast system to inform the person to be tested, so that the person to be tested can more conveniently obtain the measurement results and check the measurement records.

[0132] The following will refer to Figure 1-Figure 8 A vehicle according to a specific embodiment of the present invention is described.

[0133] like Figure 1-Figure 8 As shown, the vehicle includes a vehicle body fat and weight measurement system, a display system and a voice broadcast system.

The four safety grooves are arranged in groups of two on both sides of the steering wheel 20 in the left and right directions of the vehicle, and each group of mounting holes is arranged on the rim 21 along the front and rear directions of the vehicle. The mounting holes may be formed on the frame of the steering wheel 20 and communicated with the cavity of the frame.

[0137] The first body fat detection component 15 includes two groups of first detection electrodes 151, and the two groups of first detection electrodes 151 are arranged on the footrest 13 and are symmetrical and spaced apart on the footrest 13 along the left-right direction of the vehicle. The first detection electrode 151 includes a first excitation electrode 1511 and a first measuring electrode 1512, and the first excitation electrode 1511 and the first measuring electrode 1512 are spaced apart on the footrest 13 along the front-back direction of the vehicle. The first excitation electrode 1511 and the first measuring electrode 1512 can be fixed on the plastic trim of the face cover, and the first excitation electrode 1511 and the first measuring electrode 1512 can also be connected and fixed to the footrest frame through a plastic bracket to improve stability.

[0138] The second body fat detection component 30 includes two groups of second detection electrodes 31, and the two groups of second detection electrodes 31 are arranged corresponding to the two groups of mounting holes. Each group of second detection electrodes 31 includes a second excitation electrode 311 and a second measuring electrode 312, and the second excitation electrode 311 and the second measuring electrode 312 are respectively fixed in the two mounting holes and the mounting holes are closed. The first excitation electrode 1511, the first measuring electrode 1512, the second excitation electrode 311 and the second measuring electrode 312 can all be low-impedance metal parts such as stainless steel. Optionally, the mounting holes can be arranged at an appropriate height position of the wheel rim 21 on the vehicle, so that the hands of the person to be tested can easily and comfortably contact the second body fat detection component 30 in a straight state. The steering wheel 20 can be a two-spoke, three-spoke or four-spoke type steering wheel 20, and the hub of the steering wheel 20 can be round, D-shaped or yoke-shaped.

The control module 40 is electrically connected to the weight sensor and the body fat detection component and is communicatively connected to the display system. The display system can be electrically connected to the footrest 13 adjustment machine and is communicatively connected to the mobile terminal of the person to be tested.

[0140] In this embodiment, the vehicle-borne fat and weight measuring system is integrated into the vehicle and into structures such as the seat 10 and the steering wheel 20. When the person to be measured uses the vehicle normally, the vehicle-borne fat and weight measuring system may be in an inactive state.

[0141] When the person to be tested needs to use the vehicle-borne fat and weight measurement system to measure body fat and weight, the person to be tested can activate the vehicle-borne fat and weight measurement system and create a personal file, in which the initial information of the person to be tested, such as height, weight, and gender, is entered.

[0142] When the person to be tested sits on the seat 10 for activation operation, the person to be tested can temporarily get off the vehicle or stand up according to the prompt to reset the weight sensor, and the person to be tested sits in the seat 10 again, and the footrest 13 rises. The person to be tested can put both feet on the footrest 13 according to the prompt to lift both feet off the ground, and the vehicle-borne fat and weight measurement system measures the weight of the person to be tested. After the person to be tested confirms the weight result, the person to be tested selects his or her own personal file, and the weight result and measurement time and other data are recorded in the personal file, and the weight result can be notified to the person to be tested through a display screen or a speaker.

[0143] After the weight is measured, the display system can communicate with the controller of the seat 10 and the controller of the steering wheel 20, so that the controllers of the seat 10 and the steering wheel 20 can control the seat 10 and the steering wheel 20 to make certain position adjustments, so that the person to be tested can be more comfortable when sitting on the seat 10 and holding the steering wheel 20 for measurement. The display system can remind the person to be tested to adjust to a specified sitting posture, and the person to be tested adjusts the posture. For example, the arms of the person to be tested can be straightened to improve the accuracy of the detection, and the person to be tested holds the rim 21 of the steering wheel 20 with both hands respectively. The person to be tested can adjust the clothing at the ankle according to the prompts so that the ankle is in reliable contact with the first excitation electrode 1511 and the first measuring electrode 1512, the thumb is in contact with the second measuring electrode 312, and the palm is in contact with the second excitation electrode 311.

[0144] The vehicle-borne body fat and weight measurement system detects the body fat of the person to be tested. Exemplarily, the vehicle-borne body fat and weight measurement system can measure the impedance values ​​of the left arm, right arm, trunk, left leg and right leg of the person to be tested at 20KHz and 100KHz based on the five-segment human body electrical impedance model. The control module 40 calculates the body composition content such as the total body water (TBW), fat mass (FM) and non-fat mass (FFM) according to the impedance data, so as to obtain body fat data, and the body fat data is entered into the personal file. The display system can calculate the human mass ratio based on the body fat data combined with data such as height and compare it with historical records, so as to analyze and visualize the body fat data, and the display system informs the person to be tested of the processed body fat data through a display screen or other means.

[0145] When the person to be tested subsequently measures his body fat and body weight, the vehicle-borne body fat and body weight measurement system can perform operations such as clearing the weight sensor before the person to be tested gets on the vehicle to simplify the operation of the person to be tested and improve detection efficiency. For example, when the person to be tested unlocks the vehicle from outside the vehicle, the vehicle-borne body fat and body weight measurement system can perform self-checks in advance before the person to be tested enters the vehicle, confirm that the vehicle-borne body fat and body fat measurement system is activated, confirm that the vehicle is in a safe parking state, confirm that seat 10 is unoccupied, clear the weight sensor, and perform other operations, so that the person to be tested can measure his weight and body fat after entering the vehicle.

[0146] When the person entering does not activate the vehicle-borne fat weight measurement system for the person to be tested, when the person confirms the weight result, the person can create a new personal file as needed to store and record the data, so that the vehicle-borne fat weight measurement system can adapt to the use of multiple different persons to be tested, making the vehicle-borne fat weight measurement system more flexible and practical when used.

[0147] In this embodiment, the person to be tested can also operate through the mobile software. For example, the person to be tested can activate the vehicle-borne fat and weight measurement system, create a personal profile, enter initial data, etc. through the mobile software, thereby making the operation and use of the vehicle-borne fat and weight measurement system more convenient.

[0148] During actual use, the person being tested can use the vehicle-borne fat and weight measurement system during commuting to quickly and regularly record changes in body fat and weight, so that they can better manage their health and achieve a better physical condition.

[0149] The following will refer to Figure 1-Figure 8 A method for measuring body fat and body weight according to a third embodiment of the present invention is described.

[0150] like Figure 1-Figure 8 As shown, when the vehicle-borne fat weight measurement system is operating normally, after the vehicle is powered on or unlocked, the vehicle-borne fat weight measurement system performs a self-check. After the self-check is normal, the vehicle-borne fat weight measurement system confirms that the vehicle-borne fat weight measurement system is activated. If the vehicle-borne fat weight measurement system is activated, the vehicle-borne fat weight measurement system confirms that the vehicle is in a safe parking state. If the vehicle is in a safe parking state, the vehicle-borne fat weight measurement system confirms that seat 10 is unoccupied. If seat 10 is unoccupied, the weight sensor is reset, and the person to be tested sits in the seat body 11 of seat 10. After the vehicle-borne fat weight measurement system confirms that seat 10 is occupied, the footrest adjuster 14 controls the footrest 13 to rise to support the lower limbs of the person to be tested, and the weight sensor detects the weight of the person to be tested in real time.

[0151] After the weight data measured by the weight sensor stabilizes, the person to be tested can confirm the weight result or measure the weight again. After the person to be tested confirms the personal file, the confirmed weight data is entered into the personal file. For example, data such as the measurement time can be recorded for data processing and analysis. The weight result can be displayed on the display screen of the display system or played through the speakers of the display system.

[0152] After the vehicle-borne body fat weight measurement system confirms again that the vehicle is in a safe parking state, the vehicle-borne body fat weight measurement system reminds the person to be tested to adjust his posture for body fat detection. For example, the position of the seat 10 and the steering wheel 20 can be adjusted by the vehicle controller of the vehicle to make the person to be tested more comfortable. When the vehicle-borne body fat weight measurement system determines that the body fat detection component is in the on state, the vehicle-borne body fat weight measurement system cooperates with the body fat detection component through the control module 40 to perform body fat detection. The control module 40 processes and analyzes the obtained impedance data in combination with the weight, height, etc. of the person to be tested to obtain the composition content of the human body, thereby obtaining body fat data. The body fat data is entered into the personal file. The display system can display the body fat measurement results and analyze and visualize them according to the measurement data and historical data.

[0153] The display system will display the processed data set on the display screen or inform the person to be tested by voice prompting, so as to provide reference and suggestions for the person to be tested. The display system can upload personal files to the cloud platform so that the person to be tested can view them on the mobile software. For example, the software can achieve data exchange with other mobile health software to create a series of health intelligent connection states.

[0154] After the body fat weight measurement is completed and the person to be tested is informed, the vehicle-borne body fat weight measurement system can be in standby mode, and the person to be tested can still view personal files. When the vehicle is powered on or unlocked again, the vehicle-borne body fat weight measurement system will perform another body fat weight measurement operation.

[0155] In this embodiment, when the vehicle-borne fat weight measurement system detects a fault through self-check, the control module 40 can communicate with the display system so that the display system prompts the fault information by displaying on the display screen, etc. When the vehicle-borne fat weight measurement system confirms that the vehicle-borne fat weight measurement system is not activated, the operation of the vehicle-borne fat weight measurement system can be terminated, and the person to be tested can perform activation operations and create a personal profile so that the vehicle-borne fat weight measurement system can continue to operate.

[0156] When the vehicle-borne fat weight measurement system confirms that there is no one on the seat 10 to reset the weight sensor, if there is someone on the seat 10, the vehicle-borne fat weight measurement system can remind the person to be tested to temporarily get off the vehicle or stand up to make the seat 10 unoccupied.
