[0025] To make the technical solution and advantages of this application clearer, the following detailed description is provided in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of this application.

[0026] It should be noted that, unless otherwise specified, the embodiments and features described in this application can be combined with each other.

[0027] Furthermore, it should be noted that in the description of this application, if terms such as "upper," "lower," "inner," or "outer" appear, indicating orientation or positional relationship, these are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this application. In addition, if terms such as "first" or "second" appear, they are also used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0028] Furthermore, in the description of this application, unless otherwise expressly defined, the terms "installation," "connection," "joining," and "connector" 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 mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application in light of the specific circumstances.

[0029] In this application, the terms "one embodiment," "some embodiments," "example," "specific example," or "some examples," etc., refer to a specific feature, structure, material, or characteristic described in connection with that embodiment or example, which is included in at least one embodiment or example of this application. In this specification, the illustrative expressions of the above terms do not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any suitable manner in one or more embodiments or examples.

[0030] The present application will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0031] An embodiment of the first aspect of this application provides an armrest structure installed in a vehicle, which can expand the function of the armrest structure, improve the passenger riding experience, and thereby improve the overall quality of the vehicle.

[0032] In related technologies, armrest structures are an important component of vehicles and a core comfort feature that enhances the passenger experience. Their core function is to support the elbows of passengers, allowing them to rest and alleviate fatigue. Specifically, armrest structures can be, for example, armrest boxes for the driver and front passenger to use for elbow support; or door panel armrests for passengers who need elbow support. However, armrest structures only provide elbow support, offering a limited function and contributing to the overall quality of the vehicle's performance.

[0033] In view of this, in order to overcome the shortcomings of related technologies, the handrail structure of this embodiment combines... Figures 1 to 19 As shown, in terms of overall design, it is installed in a vehicle and includes a handrail body 100 and an extension component 200 provided on the handrail body 100.

[0034] The extension component 200 has a decorative surface 2020 and a functional surface 2030, and a functional module 204 exposed on the functional surface 2030. The functional module 204 is adapted to detect or stimulate the body of the occupant. The extension component 200 is driven to switch between a decorative state and a usage state.

[0035] Furthermore, in the decorative state, the decorative surface 2020 faces outward from the armrest body 100 and is flush with the surface of the armrest body 100. In the use state, the functional surface 2030 faces outward from the armrest body 100, and the functional module 204 can come into contact with the body of the occupant supported on the armrest body 100.

[0036] Therefore, as described above, by providing an extension component 200 with a switchable decorative surface 2020 and a functional surface 2030 on the armrest body 100, and by providing a functional module 204 on the functional surface 2030 suitable for detecting or stimulating the occupant's body, this embodiment can expand the function of the armrest structure. For example, by releasing a weak current through the functional module 204 to stimulate and regulate the occupant's vagus nerve, thereby alleviating motion sickness symptoms, it can also ensure the overall harmony of the vehicle's interior when the extended function is not used, thereby improving the occupant's driving experience and enhancing the overall quality of the vehicle.

[0037] Based on the above overview, specifically, motion sickness generally refers to kinetosis. Kinetosis, also known as motion sickness, refers to what people commonly call "car sickness, seasickness, airsickness," etc., including astronaut sickness that occurs under microgravity conditions. It is a series of physiological reactions caused by various factors leading to a misperception of motion in the human body. For example, when traveling by car, people experiencing motion sickness may exhibit symptoms such as nausea, vomiting, dizziness, paleness, or cold sweats.

[0038] Motion sickness is primarily caused by vestibular dysfunction. Excessive stimulation of the vestibular receptors in the inner ear by motion generates excessive bioelectric currents, affecting the central nervous system and resulting in reactions such as sweating, nausea, or headaches. Treatment typically involves various neurotransmitters such as anticholinergics and antihistamines. However, most of these medications are sedatives and cannot be used long-term. Furthermore, they are more likely to cause side effects in children and those with underdeveloped nervous systems.

[0039] Considering that electrical pulse (weak current) stimulation can regulate the vagus nerve and thus alleviate motion sickness symptoms, this application proposes a scheme to provide electrical pulse stimulation to passengers by releasing a weak current on the handrail body 100. Furthermore, different passengers can independently adjust the magnitude and frequency of the electrical pulse according to the severity of their motion sickness symptoms, thereby effectively alleviating their symptoms. Because the current generated by the electrical pulse generator is a weak current, it will not cause harm or adverse effects to the human body, and therefore can be used for a long time.

[0040] In other words, in specific implementation, the functional module 204 of this embodiment can be configured to release current signals (weak current) of different magnitudes and frequencies to stimulate and regulate the vagus nerve of the passenger, thereby alleviating the passenger's motion sickness symptoms. The principle of relieving motion sickness symptoms by weak current stimulation is mainly as follows: the functional module 204 periodically releases weak current, which can simulate the intensity and frequency of physiological electrical waves; based on the principle of electronic pulse regulation of vagus nerve signals, the weak current pulse stimulates the median nerve, and the current signal is transmitted to the brain nerve center, inhibiting the transmission of signals that cause nausea and dizziness between the brain and stomach from the vagus nerve, slowing down the frequency of abnormal gastric peristalsis, and thus relieving motion sickness symptoms. In addition to acting on the vagus nerve, weak current can also alleviate motion sickness symptoms through the following pathways: ① The simulated electrophysiological wave signal generated by the weak current is transmitted to the brain nerve center through the median nerve, which can block the vomiting reflex pathway between the brain and stomach, reduce abnormal gastric peristalsis related to vomiting, thereby reducing or preventing nausea and vomiting, and thus relieving motion sickness; ② By periodically releasing weak current to generate electrical stimulation, the stimulated electrical signal generated by the electrical stimulation passes through the nerve to reach the vestibular center and senses the stimulation signal, which cancels or weakens the excessive bioelectricity generated by the vestibular system due to excessive human movement, increases the tolerance of the vestibular organs to various movement stimuli, restores normal gastric movement, and thus reduces the feeling of vomiting.

[0041] Therefore, in some exemplary embodiments, functional module 204 includes an electrical stimulation module adapted to release a preset stimulation current to the occupant's body. This preset stimulation current, also known as the aforementioned weak current, generally refers to a current value within the physiological current range acceptable to the human body. Thus, by employing an electrical stimulation module capable of releasing a preset stimulation current to the occupant's body, functional module 204 can alleviate the occupant's discomfort during travel, especially motion sickness, through electrical stimulation of the occupant's body.

[0042] Furthermore, in addition to the electrical stimulation module, the functional module 204 of this embodiment can also be replaced and adjusted in some exemplary embodiments based on the functional expansion requirements of the armrest structure. For example, the functional module 204 may include a detection module suitable for detecting at least one of the occupant's heart rate and blood glucose.

[0043] Understandably, adopting a detection module that can detect the heart rate and blood sugar of occupants can enable the expansion functions of the expansion component 200, which helps to improve the quality of vehicle use.

[0044] Of course, in some exemplary embodiments of this invention, the functional module 204 may also include an electrical stimulation module adapted to release a preset stimulation current to the occupant's body, and a detection module adapted to detect at least one of the occupant's heart rate and blood glucose. The advantage of this arrangement is that it allows for more extended functions of the expansion component 200, thus better meeting the different driving and riding needs of the occupants.

[0045] Furthermore, in some exemplary embodiments, the armrest body 100 is an armrest box, door panel armrest, seat armrest, or side panel armrest in a vehicle. By providing extension components 200 at the armrest box, door panel armrest, seat armrest, or side panel armrest in the vehicle, the function of the armrest structure in the vehicle can be extended, thereby improving the overall usability of the vehicle.

[0046] Furthermore, regardless of whether the armrest body 100 is specifically a center console, door armrest, seat armrest, or side trim armrest in a vehicle, the armrest body 100 is equipped with the aforementioned extension component 200, and the extension component 200 is driven to switch between a decorative state and a usable state. Specifically, continuing with... Figure 2 and Figure 3 As shown, in the decorative state, the decorative surface 2020 faces outward from the armrest body 100 and is flush with the surface of the armrest body 100. In the use state, the functional surface 2030 faces outward from the armrest body 100, and the functional module 204 can come into contact with the body of the occupant supported on the armrest body 100.

[0047] It should be mentioned that in this embodiment, the armrest body 100 is used as a specific example of the armrest box in a vehicle for relevant introduction and explanation, and will continue to be combined with Figure 1 As shown, in some exemplary embodiments, the armrest body 100 includes a housing 101 and an elbow rest 102 disposed on the housing 101. The aforementioned extension component 200 is located on top of the elbow rest 102. Specifically, the housing 101 may be formed on the sub-dashboard assembly of the vehicle, and the elbow rest 102 may be hinged to the sub-dashboard assembly via a hinge 103 to open or close the housing 101 in a flip-up manner.

[0048] Furthermore, continue to combine Figures 4 to 8 As shown, in some exemplary embodiments, the elbow pillow 102 includes a lower elbow pillow shell 1022 and an upper elbow pillow shell 1021 disposed on the lower elbow pillow shell 1022, and the lower elbow pillow shell 1022 and the upper elbow pillow shell 1021 are detachably connected.

[0049] Specifically, the lower shell 1022 of the elbow pillow may be provided with a number of first snap hooks 10221 on its periphery, and the upper shell 1021 of the elbow pillow may be provided with a number of first snap grooves 10211 on its periphery. Each first snap hook 10221 is snapped into each first snap groove 10211 in a corresponding manner to form a snap connection between the lower shell 1022 of the elbow pillow and the upper shell 1021 of the elbow pillow, that is, to form a detachable connection between the two, ensuring that the two have good ease of disassembly and assembly.

[0050] Furthermore, the upper shell 1021 of the elbow rest is provided with a through hole for the connecting wire harness 205 connected to the functional module 204 to pass through. The connecting wire harness 205 is suitable for connecting to the vehicle end or power supply through a connector. At the same time, the upper shell 1021 of the elbow rest is also provided with a foaming element 1023, a support shell 1025 and an elbow rest skin 1024 stacked in sequence. The support shell 1025 can be used to support the elbow rest skin 1024 to ensure that the top of the elbow rest 102 has a good appearance quality. As for the relevant structural parts not mentioned in the elbow pillow 102 of this embodiment, they can be referred to the various structures in the elbow pillow 102 or armrest box that are well known to those skilled in the art, and will not be described in detail here.

[0051] It should be noted that, taking the vehicle in which the handrail structure described in this application is located as an example, the directional terms used in the embodiments, such as "up," "down," "left," "right," "front," and "rear," are defined based on the vehicle's vertical direction (also known as the height direction, or the Z-direction of the entire vehicle), horizontal direction (also known as the width direction, or the Y-direction of the entire vehicle), and front-back direction (also known as the length direction, or the X-direction of the entire vehicle). "Inner" and "outer" are defined based on the outline of the corresponding component. For example, "inner" and "outer" are defined based on the vehicle's outline, with the side of the vehicle outline closer to the middle of the vehicle being "inner," and the opposite being "outer."

[0052] In addition, continue to combine Figures 5 to 13 As shown, in some exemplary embodiments, the handrail structure of this embodiment further includes a drive assembly 300 disposed on the handrail body 100. The drive assembly 300 is drively connected to the extension assembly 200, and the drive assembly 300 is used to drive the extension assembly 200 to switch between a decorative state and a usage state.

[0053] It is understandable that by setting a drive component 300 on the armrest body 100 and using the drive component 300 to switch the extension component 200 between decorative and functional states, the technological feel of the armrest structure with the extension component 200 can be enhanced, the inconvenience of manually operating the extension component 200 can be avoided, and the quality of vehicle use can be further improved.

[0054] In some exemplary embodiments, the extension component 200 is mounted in the mounting cavity 10212 at the top of the armrest body 100 via a pivot 2010. Meanwhile, the drive component 300 includes a rotation drive unit 301 and a transmission mechanism 302 connecting the rotation drive unit 301 and the pivot 2010. The rotation drive unit 301 drives the extension component 200 to rotate via the transmission mechanism 302, and the rotated extension component 200 switches between a decorative state and a usable state.

[0055] Here, the extension component 200 is installed in the mounting cavity 10212 on the top of the handrail body 100 via the pivot 2010. This facilitates the arrangement of the extension component 200 on the handrail body 100 and allows the extension component 200 to switch between decorative and functional states. At the same time, the drive component 300 includes a rotation drive unit 301 and a transmission mechanism 302 that drives the rotation drive unit 301 to the pivot 2010 of the extension component 200. The structure is simple, easy to design and manufacture, and also easy to arrange on the handrail body 100.

[0056] In specific implementations, in some exemplary embodiments, the drive assembly 300 and the extension assembly 200 are specifically disposed on the upper shell 1021 of the elbow rest, and the mounting cavity 10212 is also formed on the upper shell 1021 of the elbow rest. Furthermore, to facilitate the accommodation of the rotary drive unit 301 and the transmission mechanism 302, a receiving cavity 10213 located on one side of the mounting cavity 10212 is also formed on the upper shell 1021 of the elbow rest, and the rotary drive unit 301 and the transmission mechanism 302 are located in the receiving cavity 10213. Meanwhile, the rotary drive unit 301 can employ a common servo motor to improve drive accuracy and drive stability.

[0057] Continue to combine Figure 12 and Figure 13 As shown, in some exemplary embodiments, the transmission mechanism 302 employs a worm gear 3021 and worm 3022 mechanism. The worm gear 3021 in the worm gear 3021 and worm 3022 mechanism is connected to the rotating shaft 2010, and the worm 3022 in the worm gear 3021 and worm 3022 mechanism is connected to the rotary drive unit 301.

[0058] The transmission mechanism 302 adopts a worm gear 3021 and worm 3022 mechanism, which enables unidirectional transmission between the rotary drive unit 301 and the expansion component 200. Only the rotary drive unit 301 can drive the expansion component 200 to rotate. At the same time, the self-locking characteristic of the worm gear 3021 and worm 3022 mechanism can be used to achieve the positioning function of the expansion component 200, which helps to ensure the stability of the position of the expansion component 200 after rotation and improves the quality of use of the expansion component 200.

[0059] In addition, continue to combine Figure 6, Figure 8 , Figures 14 to 19 As shown, in some exemplary embodiments, the extension component 200 includes a frame 201, a housing 203 connected to one end of the frame 201, and a cover 202 connected to the other end of the frame 201. Specifically, a functional surface 2030 is formed on the housing 203, and a functional module 204 is disposed on the housing 203, while a decorative surface 2020 is formed on the cover 202.

[0060] It can be understood that the expansion component 200 structurally includes a skeleton 201, and a housing 203 and a cover 202 connected to the skeleton 201, and the functional surface 2030 and the decorative surface 2020 are respectively formed on the housing 203 and the cover 202, which facilitates the design and manufacture of the expansion component 200 structure, and also facilitates the arrangement of the functional module 204 on the expansion component 200.

[0061] In some exemplary embodiments, the cover 202 is provided with a skin 2023 that covers at least the decorative surface 2020. This arrangement can improve the appearance quality of the decorative surface 2020 of the extension component 200 and help match the surface of the handrail body 100, so as to avoid affecting the overall appearance quality of the handrail structure and to ensure the appearance quality of the handrail structure.

[0062] Meanwhile, in some exemplary embodiments, the cover 202 is detachably connected to the frame 201. Therefore, the cover 202, on which the decorative surface 2020 is formed, can be replaced or adjusted based on the surface appearance of the armrest body 100, increasing the applicability of the extension component 200 and helping to reduce the application cost of the extension component 200.

[0063] In specific implementations, in some exemplary embodiments, the cover 202 and the frame 201 can be connected by a snap-fit ​​mechanism. For example, multiple second snap-fit ​​hooks 2021 are provided on the cover plate, and multiple second snap-fit ​​holes 2011 are provided on the frame 201, with each second snap-fit ​​hook 2021 snapping into each second snap-fit ​​hole 2011 in a corresponding manner.

[0064] If necessary, in some exemplary embodiments, multiple positioning posts 2022 may be provided on the cover plate and multiple positioning holes 2012 may be provided on the frame 201. During assembly, each positioning post 2022 is inserted into each positioning hole 2012 in a corresponding manner to improve the ease of assembly of the cover plate and the frame 201.

[0065] Similarly, in some exemplary embodiments, the housing 203 of this embodiment is detachably connected to the frame 201. Specifically, the housing 203 and the frame 201 are connected by a snap-fit ​​connection. For example, multiple third snap-fit ​​hooks 2013 can be provided on the frame 201, and multiple third snap-fit ​​holes 2031 can be provided on the housing 203, with each third snap-fit ​​hook 2013 correspondingly snapping into each third snap-fit ​​hole 2031.

[0066] Continue to combine Figure 6 , Figure 8 , Figures 14 to 19 As shown, in some exemplary embodiments, the housing 203 has an outwardly arched protrusion 2032 in the middle, and the protrusion 2032 has a mounting hole 20321, in which the functional module 204 is installed.

[0067] By providing an outwardly protruding portion 2032 on the housing 203, the functional module 204 is installed in the mounting hole 20321 on the protruding portion 2032, which facilitates the arrangement of the functional module 204 in the expansion component 200, and also facilitates the contact between the functional module 204 and the occupant's body, which helps to ensure the effectiveness of the functional module 204.

[0068] It should be mentioned that, under normal circumstances, when vehicles travel for long periods of time, frequently accelerate and decelerate, and turn, passengers are prone to motion sickness (the causes of motion sickness are as mentioned above and will not be repeated here), resulting in dizziness, vomiting, and other physical discomfort, which affects the comfort of the journey. Traditional vehicles do not have facilities to relieve motion sickness, and even using the elbow pillow 102 in the vehicle for elbow rest cannot effectively relieve motion sickness in a timely manner. On the other hand, using various anticholinergic, antihistamine, and other neurotransmitter drugs to treat motion sickness is problematic. Firstly, most of these drugs are sedatives and cannot be used for a long time. Secondly, they are more likely to cause side effects in children and those with underdeveloped nervous systems.

[0069] Therefore, by adopting the armrest structure in this application, the extension component 200 can be switched to the functional surface 2030. At this time, when the user needs to relieve motion sickness, he / she can rest his / her elbow on the armrest body 100 and make his / her wrist fit with the functional module 204 on the functional surface 2030. Then, the functional module 204 releases a weak current to relieve motion sickness symptoms.

[0070] In a specific implementation of this embodiment, for example, the current signal (the aforementioned weak current) released by the vehicle controller setting function module 204 can be adjusted. The adjustable range is preset to the physiological electrical signal range of a normal human body. Then, under the system prompt (via the central control screen), by changing the current signal, the current signal (i.e., physiological electrical information) suitable for each passenger is detected, and the passenger information and the corresponding current signal are stored. Subsequently, the stored information can be directly called, and the vehicle controller can control the function module 204 to release the corresponding current.

[0071] Furthermore, since the functional module 204 is located on the top surface of the elbow rest 102 and is at a stress point, it may be damaged in abnormal operating conditions, such as when the user forgets to turn off the elbow rest 102 and applies excessive pressure. To avoid this, an automatic protection function for the functional module 204 can be set in the vehicle controller. For example, a pressure sensor can be installed between the functional module 204 and the armrest body 100. When the functional module 204 is accidentally turned on and exposed, and the pressure sensor does not detect pressure, the vehicle controller will receive the pressure signal from the pressure sensor and automatically switch the elbow rest 102 to the decorative state (i.e., elbow rest mode), switching the extension component 200 from the functional state to the decorative state to protect the functional module 204.

[0072] It is worth noting that, regarding the handrail structure of this embodiment, based on the above exemplary embodiments, in specific implementation, as a preferred embodiment, it is still composed of... Figures 1 to 19 As shown, it may include, for example, a handrail body 100, and an extension component 200 and a drive component 300 disposed on the handrail body 100.

[0073] The extension component 200 has a decorative surface 2020 and a functional surface 2030, and a functional module 204 exposed on the functional surface 2030. The functional module 204 is adapted to detect or stimulate the occupant's body. The extension component 200 is driven by the drive component 300 to switch between a decorative state and a usage state. In the decorative state, the decorative surface 2020 faces outward from the armrest body 100 and is flush with the surface of the armrest body 100. In the usage state, the functional surface 2030 faces outward from the armrest body 100, and the functional module 204 can contact the body of the occupant supported on the armrest body 100.

[0074] The extension component 200 is installed in the mounting cavity 10212 on the top of the armrest body 100 via a pivot 2010. The drive component 300 includes a rotation drive 301 and a transmission mechanism 302 connected between the rotation drive 301 and the pivot 2010. The rotation drive 301 drives the extension component 200 to rotate via the transmission mechanism 302, and the rotated extension component 200 switches between a decorative state and a usage state.

[0075] The transmission mechanism 302 employs a worm gear 3021 and worm 3022 mechanism. The worm gear 3021 in this mechanism is connected to the rotating shaft 2010, and the worm 3022 is connected to the rotary drive unit 301. The extension component 200 includes a frame 201, a housing 203 connected to one end of the frame 201, and a cover 202 connected to the other end of the frame 201. A functional surface 2030 is formed on the housing 203, and a functional module 204 is disposed on the housing 203. A decorative surface 2020 is formed on the cover 202.

[0076] Furthermore, the cover 202 is provided with a skin 2023 that covers at least the decorative surface 2020; and the cover 202 is detachably connected to the frame 201. The housing 203 has an outwardly arched protrusion 2032 in its middle, and the protrusion 2032 has a mounting hole 20321 in which the functional module 204 is installed. The functional module 204 includes an electrical stimulation module adapted to release a preset stimulation current to the occupant's body, so that the weak current released by the functional module 204 can alleviate motion sickness symptoms in the vehicle occupant. The electrical stimulation module also includes electrode plates connected to an electrical pulse generator installed in the vehicle to release the preset stimulation current.

[0077] An electrode plate is a functional component that can contact human skin to establish a stable electrical connection between related equipment (such as medical physiotherapy and electrical stimulation devices) and the human body, enabling the conduction of electrical signals or the output of current, while ensuring safety, comfort, and effective conductivity. The electrode plate is mainly composed of two parts: a conductive layer and a flexible substrate. The conductive layer is a composite of a conductive carbon film and a conductive hydrogel (such as polyvinyl alcohol-based hydrogel or polymer conductive gel). The conductive carbon film provides a stable substrate for electrical signal conduction, while the conductive hydrogel can closely adhere to the skin, reduce contact resistance, and enhance the uniformity of current output. The flexible substrate, as a carrier, is made of medical non-woven fabric or medical silicone, ensuring the flexibility and skin adaptability of the electrode plate, while also being breathable to reduce skin irritation from prolonged contact.

[0078] When using functional module 204, the suitable current frequency for the human body is generally between 20-500Hz, and the suitable current intensity for the human body is generally between 4-9mA. Furthermore, by changing the current, the suitable current frequency and current intensity for each occupant can be found, stored, and directly called up later.

[0079] Among them, the armrest body 100 is the armrest box, door panel armrest, seat armrest or side trim panel armrest in the vehicle.

[0080] In the preferred embodiment of the above handrail structure, the specific settings and arrangements of the handrail body 100, the extension component 200, the drive component 300, etc. can still be referred to the descriptions in the above exemplary embodiments. Furthermore, in this preferred embodiment, the beneficial effects brought about by the design of the handrail body 100, the extension component 200, and the drive component 300 can also be referred to the descriptions in the above exemplary embodiments.

[0081] The armrest structure in this embodiment adopts the above design, which can expand the function of the armrest structure, and can also ensure the overall coordination of the vehicle interior when the expanded function is not used, so that the occupants have a better driving and riding experience and improve the overall vehicle performance.

[0082] When the functional module 204 includes an electrical stimulation module adapted to release a preset stimulation current to the occupant's body, and a detection module adapted to detect at least one of the occupant's heart rate and blood sugar, the armrest structure can release a preset stimulation current to the occupant's wrist placed on the functional surface 2030 through the functional module 204 to relieve the occupant's motion sickness symptoms, and can also detect the occupant's condition such as heart rate and blood sugar through the functional module 204.
