Description

Technical Field

[0001] This application relates to the field of training equipment technology, and more specifically, to a human body pressure detection device and a human body pressure detection system. Background Technology

[0002] Human body pressure detection devices are typically used to detect the pressure value of an external device when a user's body is squeezed by that device.

[0003] Current human stress detection devices primarily use sensors on external equipment to record pressure during exercise, or wear sensors on the body to detect pressure between the body and external equipment (e.g., firearms, bows and arrows, basketballs, volleyballs, rackets, etc.). These devices evaluate various indicators of the athlete during exercise, but they struggle to accurately identify and monitor individual movements. This results in non-standard movements requiring extensive training to detect or correct. Therefore, precise monitoring of the target user's exercise process is needed to provide accurate training guidance.

[0004] In other words, current human pressure detection devices cannot provide comprehensive pressure data distribution. Utility Model Content

[0005] The purpose of this application is to provide a human body pressure detection device and a human body pressure detection system, which acquires pressure data between body parts of the target user during exercise or movement, and transmits it to a data processing device. The data processing device analyzes the pressure data to obtain comprehensive pressure data of the target user under external equipment pressure or the force between body parts, thereby enabling more accurate monitoring of the pressure experienced by the target user.

[0006] In a first aspect, this application provides a human body pressure detection device, including a wearable component and a pressure sensor; the wearable component is provided with at least one monitoring position; wherein, the monitoring position includes a position on the wearable component corresponding to a point on which compression occurs between body parts of the target user during movement when the wearable component is worn on the target user; the pressure sensor is disposed on the monitoring position; the pressure sensor is configured to acquire pressure data received at the monitoring position and transmit it to a data processing device.

[0007] The aforementioned human body pressure detection device acquires pressure data corresponding to the locations on the wearable device where compression occurs between body parts during the target user's movement through pressure sensors installed on the wearable device. This data is then transmitted to a data processing device, which analyzes the pressure data to accurately detect the pressure between body parts during the target user's movement or actions. This allows for a more comprehensive understanding of the target user's physical rehabilitation status, body posture, and whether their force application is correct, thereby achieving effective rehabilitation training and exercise results.

[0008] In conjunction with the first aspect, optionally, the monitoring location also includes the location on the wearable device corresponding to the body part of the target user that is being squeezed between the target user and the external device when the wearable device is worn on the target user.

[0009] The aforementioned human body pressure detection device, based on the placement of pressure sensors on the wearable device at locations where pressure occurs between body parts during the target user's movement, also places pressure sensors on the wearable device at locations where pressure occurs between the target user and external equipment. This increases the sources of pressure data, thereby enabling more comprehensive monitoring of the pressure experienced by the target user. Ultimately, by comprehensively analyzing and judging the forces between body parts and the forces between the body and external equipment, it achieves a more comprehensive understanding of the target user's physical rehabilitation status, body posture, and whether their force application is correct, thus achieving effective rehabilitation training and effective exercise results.

[0010] In conjunction with the first aspect, optionally, at least one of the pressure sensors is provided at each of the monitoring locations.

[0011] The aforementioned human body pressure detection device increases the pressure data at each monitoring location by setting at least one pressure sensor at each monitoring location. This allows for the analysis of the direction of pressure or force position shift at a single monitoring location by examining the distribution of multiple pressure data at that location. Consequently, it further improves the accuracy and comprehensiveness of analyzing the target user's movements and postures during actions.

[0012] In conjunction with the first aspect, optionally, the pressure sensor is disposed on the wearable device by means of sewing, weaving, pasting, magnetic attraction, fastening, riveting, or embedding.

[0013] The aforementioned human body pressure detection device improves the stability of the pressure sensor during wear and simplifies the installation process by using methods such as sewing, weaving, pasting, magnetic attraction, fastening, riveting, or embedding to set the pressure sensor.

[0014] In conjunction with the first aspect, optionally, the pressure sensor is a flexible thin-film pressure sensor.

[0015] The aforementioned human body pressure detection device, due to its flexible thin-film pressure sensor, can better fit the human body, ensuring the accuracy of pressure information acquisition at the monitoring location. Furthermore, the flexible thin-film pressure sensor is lightweight and soft, making it easy to wear and use, and improving user comfort. In addition, the flexible thin-film pressure sensor has a large working range, making it suitable for a wide range of pressure detection needs, thereby improving the applicability of the human body pressure detection device.

[0016] In conjunction with the first aspect, optionally, the pressure sensor is a flexible capacitive pressure sensor, which includes a first electrode layer, a dielectric layer and a second electrode layer stacked sequentially; the dielectric layer is a porous structure layer that can be elastically deformed.

[0017] The aforementioned human body pressure detection device, by employing a porous dielectric layer, improves the response sensitivity of the flexible thin-film pressure sensor, thereby further enhancing the detection accuracy of the flexible capacitive pressure sensor, and consequently improving the detection accuracy of the human body pressure detection device. Furthermore, its elastic and variable characteristics allow the flexible capacitive pressure sensor to operate within varying pressure ranges, thus expanding the applicability of the human body pressure detection device.

[0018] In conjunction with the first aspect, optionally, the first electrode layer and / or the second electrode layer includes a substrate layer and a silver paste layer; the silver paste layer is located on the side of the substrate layer facing the dielectric layer.

[0019] The aforementioned human body pressure detection device has a first electrode layer and a second electrode layer formed by a substrate layer and a silver paste layer, which have good conductivity. The silver paste layer is tightly bonded to the substrate layer, ensuring the flexibility, thinness and structural stability of the pressure sensor, giving the pressure sensor good sensitivity, and indirectly ensuring the monitoring accuracy of the human body pressure detection device.

[0020] In conjunction with the first aspect, optionally, the first electrode layer and / or the second electrode layer include a conductive cloth.

[0021] The aforementioned human body pressure detection device, by using conductive cloth to form the first electrode layer and / or the second electrode layer, enables the pressure sensor to have good durability. The first electrode layer and / or the second electrode layer made of conductive cloth can be stretched or compressed in any direction to ensure good conductivity, avoiding the failure of the pressure sensor due to the damage of the electrode layer, and is more suitable for human body pressure detection.

[0022] In conjunction with the first aspect, optionally, the dielectric layer further contains conductive filler, and an insulating layer is provided between the first electrode layer and / or the second electrode layer and the dielectric layer.

[0023] The aforementioned human body pressure detection device incorporates conductive filler into the dielectric layer. This conductive filler, dispersed throughout the dielectric layer's structure, allows for a more significant change in the dielectric constant during compression deformation. This greatly enhances the response sensitivity of the capacitive pressure sensor, ensuring its sensitivity in pressure detection and improving the pressure detection range and monitoring accuracy of the device. Simultaneously, the addition of an insulating layer mitigates the risk of pressure sensor breakdown during compression deformation, preventing damage and ensuring the long-term effectiveness of the pressure sensor during use.

[0024] In conjunction with the first aspect, the wearable device may optionally include limb wearable devices and / or trunk wearable devices.

[0025] The aforementioned human pressure detection device, by specifically defining the wearable components as limb wearable components and / or torso wearable components, allows for the selection of corresponding wearable components for different needs during different movements or actions, thereby meeting the diverse application scenarios of pressure monitoring.

[0026] In conjunction with the first aspect, the wearable component may optionally include adhesive and / or woven components.

[0027] The aforementioned human body pressure detection device allows the pressure sensor to be worn on the human body via adhesive and / or woven components, thus adapting to different wearing methods required for different wearing positions. Specifically, for monitoring points that can be directly attached to the skin, the pressure sensor can be attached to the body using the adhesive component. For monitoring positions where adhesive is inconvenient, the pressure sensor can be installed on the woven component corresponding to the monitoring position, thereby improving the applicability and scenarios of the applicant's human body pressure detection device.

[0028] In conjunction with the first aspect, optionally, the woven component is an elastic fabric component.

[0029] The aforementioned human pressure detection device uses elastic fabric as the wearable component, which makes the wearable component more elastic and thus allows it to adapt to target users of different body types. Furthermore, the elastic fabric conforms more closely to the human body after being worn, ensuring the consistency between the monitoring position and the pressure position to be measured, and ensuring that the pressure sensor can be accurately set at the position to be detected.

[0030] Secondly, this application provides a human body pressure detection system, including a human body pressure detection device and a data processing device as described in the first aspect.

[0031] The aforementioned human pressure detection system has the same beneficial effects as the first aspect, which will not be elaborated here. Attached Figure Description

Detailed Implementation

[0040] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and shown in the accompanying drawings can generally be arranged and designed in various different configurations.

[0042] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0043] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the utility model product is in use.

Therefore, they should not be construed as limitations on this application.

[0046] Please refer to Figures 1 to 5 , Figure 1 This is a schematic diagram of the first structure of the human body pressure detection device 100 provided in the embodiments of this application; Figure 2 This is a schematic diagram of a second structure of the human body pressure detection device 100 provided in the embodiments of this application; Figure 3 This is a schematic diagram of the third structure of the human body pressure detection device 100 provided in the embodiments of this application; Figure 4 This is a fourth structural schematic diagram of the human body pressure detection device 100 provided in the embodiments of this application; Figure 5 This is a fifth structural schematic diagram of the human body pressure detection device 100 provided in this application embodiment. The human body pressure detection device 100 provided in this application embodiment includes a wearable component 110 and a pressure sensor 120; the wearable component 110 is provided with at least one monitoring position 130; wherein, the monitoring position 130 includes a position on the wearable component 110 corresponding to the point where the body parts of the target user are compressed during movement when the wearable component 110 is worn by the target user; the pressure sensor 120 is disposed on the monitoring position 130; the pressure sensor 120 is configured to acquire the pressure data received at the monitoring position 130 and transmit it to a data processing device.

[0047] Monitoring pressure between body parts can be applied to various sports scenarios, such as self-resistance training in rehabilitation exercises. Self-resistance training involves using one's own strength to resist one's own movements, such as shoulder stretching (crossing one arm across the body and gently pressing down with the other arm to stretch the shoulder [first monitoring position]), neck stretching (gently pressing down on the head with one hand to tilt the head to one side to stretch the neck [second monitoring position]), knee flexion and extension (grabbing the ankle with one hand and gently bending and extending the knee [third monitoring position]), and wrist and finger stretching and flexion (grabbing the fingers or wrist of the other hand with one hand to stretch and bend), etc. For example, in yoga, many poses involve compression between body parts, such as Tree Pose (placing the sole of one foot against the inside of the other leg, then bringing the hands together in front of the chest or overhead [fourth monitoring position]), Deer Pose (sitting on the ground, placing the sole of one foot against the thigh of the other leg, then hugging the knee with the hands), and Pigeon Pose (bending one leg in front of the body, extending the other leg behind the body, then grasping the ankle of the back leg with the hands). Another example is the contact between limbs in the volleyball stroke. Yet another example is the contact between the hand and face in shooting training.

[0048] Wearable item 110 may be at least one of finger sleeves, gloves, vests, and waistcoats.

[0049] The pressure data collected by the pressure sensor 120 can be transmitted to the data processing device via either wired or wireless communication. The pressure data collected by the pressure sensor 120 can also be transmitted directly or indirectly to the data processing device.

[0050] As an optional implementation, the pressure sensor 120 can be communicatively connected to a data transmission module. The pressure sensor 120 can be configured to transmit the pressure data it collects to the data transmission module, and the data transmission module can be configured to transmit the pressure data received from the pressure sensor 120 to a data processing device. The data processing device can be integrated into the wearable device 110 or not. The data processing device can be an electronic device such as a computer capable of analyzing the training status of the target user using the pressure data.

[0051] In the above implementation process, the pressure sensor 120 set on the wearable device 110 acquires the pressure data corresponding to the position on the wearable device 110 where the body parts of the target user are squeezed during the exercise, and transmits it to the data processing device. The data processing device analyzes the pressure data to accurately detect the pressure between the body parts of the target user during the exercise or movement, thereby achieving a more comprehensive understanding of whether the target user's physical rehabilitation status, body posture and force exertion are correct, so as to achieve effective rehabilitation training, effective exercise and other exercise results.

[0052] Please continue to refer to Figures 1 to 5 In some alternative implementations, the monitoring location 130 may also include a location on the wearer 110 corresponding to the body part of the target user that is being squeezed between the target user and an external device when the wearer 110 is worn on the target user.

[0053] External devices can be shooting equipment, such as rehabilitation equipment, fitness equipment, firearms, bows and arrows, etc. During shooting training, the user's hand will be squeezed against the shooting equipment. External devices can also be sports and fitness equipment, such as basketballs, volleyballs, table tennis rackets, etc. During sports and fitness activities, the user's hand will come into contact with the basketball or volleyball, resulting in compression, or the user's hand will be squeezed against the racket while holding it.

[0054] In the above implementation process, based on the placement of pressure sensors 120 on the wearable device 110 at the locations where pressure occurs between body parts during the target user's movement, pressure sensors 120 are also placed at the locations on the wearable device 110 at the locations where pressure occurs between the target user and external devices. This increases the sources of pressure data, thereby enabling more comprehensive monitoring of the pressure experienced by the target user. Ultimately, by comprehensively analyzing and judging the forces between body parts and the forces between the body and external devices, a more comprehensive understanding of the target user's physical rehabilitation status, body posture, and whether the force exertion is correct is achieved, thereby achieving effective rehabilitation training and effective exercise results.

[0055] Please continue to refer to Figures 1 to 5 In some alternative implementations, at least one pressure sensor 120 is provided at each monitoring location 130.

[0056] Each monitoring location 130 can be equipped with 2, 3, 4, or other pressure sensors 120. The number of pressure sensors at different monitoring locations 130 can be the same or different.

[0057] In the above implementation process, by setting at least one pressure sensor 120 at each monitoring position 130, the pressure data of a single monitoring position 130 is increased. This allows the distribution of multiple pressure data at a single monitoring position 130 (such as the distribution of pressure value magnitude, presence or absence of pressure value, etc.) to analyze the direction of pressure or the force position shift of the single monitoring position 130, thereby further improving the accuracy and comprehensiveness of analyzing the posture of the target user during movement and action.

[0058] In some alternative embodiments, the pressure sensor 120 is disposed on the wearable part 110 by means of sewing, weaving, pasting, magnetic attraction, fastening, riveting or embedding.

[0059] In the above implementation process, the pressure sensor 120 is set by means of sewing, weaving, pasting, magnetic attraction, fastening, riveting or embedding, which improves the stability of the pressure sensor 120 during the wearing process and simplifies the installation method of the pressure sensor 120.

[0060] In some alternative implementations, the pressure sensor 120 is a flexible thin-film pressure sensor 120.

[0061] In the above implementation process, the flexible thin-film pressure sensor 120 can better fit the human body, ensuring the accuracy of pressure information acquisition at the monitoring location. Furthermore, the flexible thin-film pressure sensor is lightweight and soft, making it easy to wear and use and improving user comfort. In addition, the flexible thin-film pressure sensor 120 has a large working range and is suitable for a wide range of pressure detection needs, thereby improving the applicability of the human body pressure detection device 100.

[0062] Please refer to Figure 6 , Figure 6 This is a schematic diagram of the structure of the pressure sensor 120 in the human body pressure detection device 100 provided in this application embodiment. In some optional embodiments, the pressure sensor 120 is a flexible capacitive pressure sensor 120, which includes a first electrode layer 121, a dielectric layer 122 and a second electrode layer 123 stacked sequentially; the dielectric layer 122 is a porous structure layer that can be elastically deformed.

[0063] In the above implementation process, by employing a porous dielectric layer 122, the response sensitivity of the flexible thin-film pressure sensor is improved, thereby further improving the detection accuracy of the flexible capacitive pressure sensor 120, which in turn improves the detection accuracy of the human body pressure detection device 100. Furthermore, the elastic and variable characteristics allow the flexible capacitive pressure sensor 120 to operate within different pressure ranges, thus expanding the applicability of the human body pressure detection device 100.

[0064] Please continue to refer to Figure 6 In some alternative embodiments, the first electrode layer 121 and / or the second electrode layer 123 include a substrate layer 1211 and a silver paste layer 1212; the silver paste layer 1212 is located on the side of the substrate layer 1211 facing the dielectric layer 122.

[0065] In the above implementation process, the first electrode layer 121 and the second electrode layer 123 formed by the substrate layer 1211 and the silver paste layer 1212 have good conductivity. The silver paste layer 1212 is tightly bonded to the substrate layer 1211, which ensures the flexibility, thinness and structural stability of the pressure sensor 120, and makes the pressure sensor 120 have good sensitivity, which indirectly ensures the monitoring accuracy of the human body pressure detection device 100.

[0066] In some alternative embodiments, the first electrode layer 121 and / or the second electrode layer 123 include a conductive cloth.

[0067] In the above implementation process, the pressure sensor 120 has good durability by using conductive cloth to form the first electrode layer 121 and / or the second electrode layer 123. The first electrode layer 121 and / or the second electrode layer 123 made of conductive cloth can maintain good conductivity even when stretched or compressed in any direction, avoiding the failure of the pressure sensor due to the damage of the electrode layer, and is also more suitable for detecting human body pressure.

[0068] Please continue to refer to Figure 6 In some optional embodiments, conductive filler is also dispersed in the dielectric layer 122, and an insulating layer 124 is provided between the first electrode layer 121 and / or the second electrode layer 123 and the dielectric layer 122.

[0069] In the above implementation process, by adding conductive filler to the dielectric layer 122, the conductive filler is dispersed in the structure of the dielectric layer 122, so that the dielectric constant of the dielectric layer 122 can change more significantly during compression deformation. This greatly improves the response sensitivity of the capacitive pressure sensor, thereby ensuring the sensitivity of the pressure sensor 120 to pressure detection and improving the pressure detection range and monitoring accuracy of the applicant's human body pressure detection device. At the same time, due to the increase of conductive filler, the pressure sensor 120 may be at risk of breakdown during compression deformation. Adding an insulating layer 124 can prevent the pressure sensor from being broken down, avoid damage to the pressure sensor 120, and ensure the long-term effectiveness of the pressure sensor 120 during use.

[0070] In some alternative embodiments, the wearable device 110 includes limb wearable devices 110 and / or trunk wearable devices 110.

[0071] Limb wearables 110 can be finger cots, gloves, sleeves, etc. Torso wearables 110 can be vests, undershirts, etc.

[0072] In the above implementation process, by specifically defining the wearable device 110 as a limb wearable device 110 and / or a torso wearable device 110, the corresponding wearable device can be selected according to the needs of different sports or movement processes to meet different application scenarios of pressure monitoring.

[0073] In some alternative embodiments, the wearable component 110 includes adhesive and / or woven components.

[0074] The adhesive part can be Velcro, and the woven part can be a wearable part 110 made of woven fabric.

[0075] In the above implementation process, the pressure sensor 120 can be specifically determined as an adhesive piece and / or a woven piece, and worn on the human body, so as to be applicable to different wearing methods required for different wearing positions. Specifically, after determining the monitoring point at the location where it can be directly attached to the human skin, the pressure sensor 120 can be attached to the human body using the adhesive piece. For the monitoring position 130 where it is inconvenient to use an adhesive piece, the pressure sensor 120 can be installed on the woven piece corresponding to the monitoring position 130, thereby improving the applicability and scenarios of the human body pressure detection device of this applicant.

[0076] In some alternative implementations, the woven part is an elastic fabric.

[0077] Elastic fabrics can be diene elastic fibers (rubber filaments), polyurethane fibers (spandex), polyether ester elastic fibers, composite elastic fibers (T400 fibers), polyolefin elastic fibers (DOW XLA fibers), etc.

[0078] In the above implementation process, by using an elastic fabric as the wearable part 110, the wearable part 110 has better elasticity, thereby enabling the wearable part 110 to adapt to target users of different body types. Moreover, after the elastic fabric is worn, it fits the human body shape better, which can ensure the consistency between the monitoring position 130 and the pressure position to be measured, and ensure that the pressure sensor 120 can be accurately set at the position to be detected.

[0079] Based on the same concept, this application provides a human body pressure detection system, including the human body pressure detection device 100 described above and a data processing device.

[0080] The above implementation process is the same as that of the human body pressure detection device 100 provided earlier, and will not be repeated here.

[0081] The above description is merely a preferred embodiment of this application and is not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
