In general, the specific meanings of the above terms will be understood by those of ordinary skill in the art as appropriate.

The following describes an implementation of a load recording structure according to the present invention in detail with reference to fig. 1 to 4.

It should be noted that the load recording structure 10 is mainly used for monitoring and recording the load condition of the stressed body. The "load condition" may include the weight of the load of the force-bearing body, the duration of the load, and so on, and the specific load condition may cover which parameters, which may be determined according to the actual needs. For convenience of description, a portion of the urging body that contacts a force receiving portion of the force receiving body is referred to as an urging portion 20.

It should be noted that the "force application main body" mentioned in the present invention can be an apparatus such as a dumbbell, a barbell, etc., a handbag, a backpack of various shoulders and single shoulders, such as a shoulder-carried schoolbag, a computer bag or a mountaineering bag, and what is specifically adopted as the force application main body can be determined according to actual needs. Correspondingly, the term "force-receiving body" as used herein generally refers to a part of a user, such as a shoulder or a hand of a human body, but may be any other suitable force-receiving part of a force-receiving body.

As shown in fig. 1 and 2, the load recording structure 10 includes a backing tape 100, a pressure sensor 200, and a control unit 300. The backing strip 100 includes a first force-bearing segment 110, and the first force-bearing segment 110 has a force-bearing surface 111 and a contact surface 112. In the present embodiment, during load monitoring, as shown in fig. 3, the first force receiving section 110 is located between the force receiving portion of the force receiving body and the force applying portion 20 of the force applying body, and the force receiving surface 111 of the first force receiving section 110 is in contact with the force applying portion 20 of the force applying body, and correspondingly, the contact surface 112 of the first force receiving section 110 is in contact with the force receiving portion of the force receiving body. It will be appreciated that the contact face 112 of the first force-bearing segment 110 is opposite its force-bearing face 111. For example, in the case of a shoulder-carried schoolbag as the force application body, the force application body is usually the shoulder of the user, and the force application part 20 of the force application body is usually the part of the schoolbag strap contacting with the shoulder of the user. Correspondingly, the force bearing surface 111 is a surface of the first force bearing section 110 facing the schoolbag strap, and the contact surface 112 is a surface of the first force bearing section 110 facing the shoulders. Alternatively, in the case where the force application body is a dumbbell, the force receiving body is usually the hand of the user, and the force application portion 20 of the force application body is usually the portion of the dumbbell that contacts the palm of the hand. Correspondingly, the force-bearing surface 111 is a dumbbell-facing surface of the first force-bearing segment 110, and the contact surface 112 is a palm-facing surface of the first force-bearing segment 110.

In this embodiment, as shown in fig. 3, when the load recording structure 10 needs to be used, a user can directly wind one end of the first force receiving segment 110 of the load recording structure 10 around the force applying portion 20 from one side of the force applying portion 20 of the force applying body, and wind the other end of the first force receiving segment 110 around the force applying portion 20 from the other side of the force applying portion 20 of the force applying body, and one end of the first force receiving segment 110 is detachably connected to the other end of the first force receiving segment 110, so that the user can separately set the load recording structure 10 on the force applying portion 20 of the force applying body by detachably connecting the two ends of the first force receiving segment 110, and when the use is not needed or the force applying condition of other force applying bodies needs to be monitored, the user can directly release the connection between the two ends of the first force receiving segment 110, and detach the load recording structure 10 from the force applying portion 20 of the previous force applying body, and then, the load recording structure 10 is mounted on the force application part of the next force application body according to the above-mentioned mounting manner of the load recording structure 10, and obviously, the use scene of the load recording structure 10 can be greatly widened.

It can be understood that, in the present embodiment, the first force bearing segment 110 can be used as the main force bearing part of the lining belt 100, and is located below the force application part 20 of the force application body and is in contact with the first force bearing segment 110. Since the pressure sensor 200 is disposed on the first force-bearing segment 110, the load applied to the force-bearing body by the force-applying body can be monitored directly through the pressure sensor 200. As shown in fig. 1, in the present embodiment, in order to improve the sensing sensitivity of the pressure sensor 200, the pressure sensor 200 is disposed on the force-bearing surface 111 of the first force-bearing stage 110, so as to ensure that the pressure sensor 200 can directly contact the force-applying portion 20 of the force-applying body when in use. In addition, in order to improve the bending resistance of the product and further improve the sensing sensitivity of the pressure sensor 200, the pressure sensor 200 is preferably a flexible thin film piezoresistive sensor, for example, an FSR402 thin film pressure sensor, specifically, as shown in fig. 1 and 2, the pressure sensor 200 is in a thin film shape, and the thin film pressure sensor is flatly arranged on the force bearing surface 111 of the first force bearing section 110, so that when the force bearing surface 111 is mounted on the force bearing body and bears the force, the pressure (gravity) of the force bearing body can be sensitively sensed, and the piezoelectric data can be accurately transmitted. Further, when in use, the control unit 300 receives and processes the piezoelectric data transmitted from the film-like pressure sensor 200 to finally obtain weight data of the force application body; of course, in practice, the pressure sensor 200 may be another suitable type of pressure sensor 200, and the specific requirement may be determined according to actual needs.

In order to process the stress data monitored by the pressure sensor 200, as shown in fig. 2 and 4, the control module 300 disposed on the backing tape 100 is electrically connected to the pressure sensor 200, and the control module 300 is further connected to an external terminal (not shown) by signals. It can be understood that, in the present embodiment, the pressure sensor 200 mainly converts the sensed pressure into the resistance, then the pressure sensor 200 transmits the resistance data to the control component 300, and after the control component 300 receives the resistance data, the data is analyzed and processed, so as to obtain the load information such as the load weight and the load duration, and record the load information, of course, a time recording module capable of recording time and the like are arranged in the control component 300, so that the control component 300 can record the load duration and the like; in this way, the user can read the user's load information recorded in the load recording structure 10 directly and periodically by using an external terminal, and can perform operations such as clearing as needed. In fact, the external terminal can also upload the read load information of the user to the cloud for further data analysis, mining and other operations, so that the load data suitable for the user, such as the optimal load size, the load time and the like, can be obtained, and therefore the user health can be guided or referred, and obviously, the use function of the load recording structure 10 is greatly expanded.

It should be noted that, in this embodiment, the external terminal may be a mobile phone or a tablet computer, and actually, the user may select a suitable external terminal according to actual needs.

In one embodiment, as shown in fig. 1 to 3, in order to facilitate the winding of the load recording structure 10 on the force application portion 20 of the force application body and to improve the monitoring stability of the load information, the lining tape 100 further includes a second force bearing section 120, and the second force bearing section 120 is disposed at one end (e.g., the right end) of the first force bearing section 110. In addition, a control assembly 300 is disposed within the second force bearing segment 120. Specifically, as shown in fig. 3, in the use state of the load recording structure 10, the second force-bearing section 120 of the liner tape 100 is wound around the force-applying portion 20 from one side (e.g., right side) of the force-applying portion 20 of the force-applying body, and is detachably connected to the other end (e.g., left end) of the first force-bearing section 110.

It will be appreciated that in use of the load-bearing recording structure 10, the force-applying portion 20 of the force-applying body is located between the first and second force-bearing segments 110, 120 of the backing tape 100; the first bearing section 110 is a main bearing part of the lining belt 100, the second bearing section 120 is a secondary bearing part of the lining belt 100, and the second bearing section 120 is mainly used for wrapping the control assembly 300 and is detachably connected with the other end of the first bearing section 110. In addition, since the control unit 300 is usually a hard component, the comfort of the user when loading can be improved by disposing the control unit 300 on the second force-bearing section 120.

In one embodiment, as shown in fig. 1 to 3, in order to facilitate the connection between the first bearing segment 110 and the second bearing segment 120, improve the bending resistance of the load-bearing recording structure 10, and the like, the backing tape 100 further includes a first connecting tape 130 having elasticity, wherein the second bearing segment 120 is connected to one end (e.g., the right end) of the first bearing segment 110 through the first connecting tape 130. In other words, the first and second bearing sections 110 and 120 are connected to both ends of the first connecting band 130, respectively. As can be appreciated, because the first connecting band 130 has elasticity, the overall length of the backing band 100 can be extended and contracted within a certain range, thereby facilitating the backing band 100 to be able to adapt to the winding requirements of the force application parts 20 of force application bodies of different sizes.

In one embodiment, as shown in fig. 2, the load recording structure 10 further includes a connecting wire 140, wherein the connecting wire 140 is disposed inside the first connecting strip 130, in other words, the connecting wire 140 is wrapped by the first connecting strip 130, so as to prevent the connecting wire 140 from directly contacting with the outside and causing excessive wear. In order to transmit signals between the pressure sensor 200 and the control component 300, two ends of the connection wire 140 are electrically connected to the pressure sensor 200 and the control component 300, respectively. In addition, in the embodiment, the length of the connection wire 140 can be extended and contracted between the first force-bearing section 110 and the second force-bearing section 120, so that the connection wire 140 can be prevented from being broken during the winding and contraction process of the lining tape 100, which may cause the electrical connection between the control assembly 300 and the pressure sensor 200 to be interrupted. Preferably, as shown in fig. 2, the connection line 140 is a serpentine connection line 140.

In one embodiment, as shown in fig. 2, for the same reason, to facilitate the winding of the load recording structure 10 on the force application part 20 of the force application body and to improve the monitoring stability of the load information of the user, the lining tape 100 further includes a connection section 150, wherein the connection section 150 is disposed on the other end (e.g., left end) of the first force bearing section 110, and it can be understood that the connection section 150, the first force bearing section 110 and the second force bearing section 120 are sequentially connected end to end. In addition, in the present embodiment, as shown in fig. 3, during the use of the lining tape 100, the connection segment 150 is wound around the force application part 20 from the other side (e.g., the left side) of the force application part 20, and the connection segment 150 is detachably connected to the second force bearing segment 120.

In this embodiment, as shown in fig. 1 and 2, the lining band 100 further includes a second connection band 160 having elasticity, wherein the connection segment 150 is connected to the other end (e.g., left end) of the first bearing segment 110 by the second connection band 160. In other words, the first bearing section 110 and the connection section 150 are connected to both ends of the second connection band 160, respectively. Therefore, on one hand, the whole length of the lining belt 100 can be expanded and contracted within a certain range, so that the lining belt 100 can be conveniently adapted to the winding requirements of the force application parts 20 of the force application main bodies with different sizes; on the other hand, the bending resistance of the load-bearing recording structure 10 can be improved.

It should be noted that, in the present embodiment, in order to improve the comfort of the user using the load recording structure 10 under a load, the first force-bearing section 110, the second force-bearing section 120 and the connecting section 150 are all foam pads. Furthermore, as shown in fig. 1 and 3, the thicknesses of the sponge cushions adopted by the first force bearing section 110, the second force bearing section 120 and the connecting section 150 are gradually reduced. Specifically, the thickness of the first force-bearing section 110 is the largest, so that the sponge cushion with larger thickness can greatly improve the comfort degree of the user when the user bears the weight because the first force-bearing section 110 is in contact with the stressed part of the stressed main body; the thickness of the second bearing section 120 is the smallest, and the thickness of the connecting section 150 is the smallest, so that on one hand, the second bearing section 120 can be ensured to effectively protect parts such as the control assembly 300 arranged inside the second bearing section 120, and on the other hand, the gripping difficulty of the user for the wound lining strip 100 can be reduced.

In the present embodiment, as shown in fig. 3, in order to ensure the winding stability of the load recording structure 10 and to reduce the bending probability of the second force bearing section 120 as much as possible, when the force applying portion 20 of the force applying body is a shoulder strap during use, the length of the extended first connecting strap 130 is generally equal to or greater than the sum of the thickness of the first force bearing section 110 and the thickness of the force applying portion 20 of the force applying body, and finally the entire second force bearing section 120 can be ensured to cover the force applying portion 20 above the force applying portion 20 of the force applying body.

In one embodiment, as shown in fig. 2, in order to achieve the purpose of winding the lining tape 100 around the force application portion 20 of the force application body and then detaching the lining tape 100, or in order to achieve the purpose of detachable connection between the lining tape 100 and the force application portion 20 of the force application body, the free end of the second force bearing section 120 is provided with a first connection structure 121, the free end of the connection section 150 is provided with a second connection structure 151, and the first connection structure 121 is detachably connected to the second connection structure 151. It should be noted that the detachable structure formed between the first connecting structure 121 and the second connecting structure 151 may be a detachable slot and a snap-fit structure, a slot and a hook-fit structure, etc., or other suitable detachable structures.

Specifically, in the present embodiment, as shown in fig. 3, a hook and loop fastener structure is formed between the first connecting structure 121 and the second connecting structure 151, and more specifically, the first connecting structure 121 is a bristle part of a hook and loop fastener (also can be a round bristle part of a hook and loop fastener), correspondingly, the second connecting structure 151 is a round bristle part of a hook and loop fastener (also can be a bristle part of a hook and loop fastener), and when in use, the bristle part is attached to the round bristle part. In order to ensure the stability of the two attaching parts, the area occupied by the round hairs in the round hair part is larger than that occupied by the stabbing hairs in the stabbing hair part.

In one embodiment, as shown in fig. 2, in order to increase the friction between the first force-bearing segment 110 and the force-bearing portion of the force-bearing body and avoid the relative displacement between the backing strip 100 and the force-applying portion 20 of the force-applying body during the use of the load recording structure 10, an anti-slip structure 1121 is disposed on the contact surface 112 of the first force-bearing segment 110. In this embodiment, the anti-slip structure 1121 is an anti-slip particle, preferably an anti-slip colloidal particle, wherein the anti-slip colloidal particle may be integrally disposed on the contact surface 112 of the sponge pad corresponding to the first force-bearing section 110.

In one embodiment, as shown in FIG. 2, the load-bearing recording structure 10 further comprises a battery 400, wherein the battery 400 is a battery with a cylindrical hard housing, which is advantageous for improving the flexibility of the load-bearing recording structure 10, and for reducing the probability of damage to the devices in the load-bearing recording structure 10 because the hand-held posture of the user can match the cylindrical battery 400 when the force-applying body is a dumbbell when the dumbbell is held by the hand.

In order to protect the battery 400 conveniently, the battery 400 is arranged in the second force bearing section 120, the axial direction of the battery 400 is consistent with the width direction of the backing tape 100 in order to improve the bending capability of the backing tape 100, and the backing tape 100 is wound on the force application part 20 of the force application main body around the axial direction of the battery 400, so that the battery 400 is not bent along with the winding action of the backing tape 100, and the use safety of the battery 400 is ensured.

In the present embodiment, as shown in fig. 2, the control assembly 300 includes a flexible circuit board 310, an induction coil 320, and a controller (not shown). In the second bearing section 120, the flexible circuit board 310 is disposed at the end of the battery 400 (specifically, the end corresponding to the negative electrode of the dry battery), because the casing of the battery 400 is a hard casing with a certain rigidity, the casing can bear a certain pressure, in other words, the casing of the battery 400 can bear most of the stress, so that the rigidity of the end of the battery 400 can be fully utilized, the stress on the flexible circuit board 310 is reduced, and the probability of deformation of the flexible circuit board 310 when the backing tape 100 is wound on the force application portion 20 of the force application main body is reduced. In addition, the induction coil 320 is attached to the arc outer side wall of the battery 400, so that the lateral area of the cylindrical battery 400 and the rigidity of the outer shell of the battery 400 can be utilized to reduce the stress of the induction coil 320, and further prevent the induction coil 320 from being distorted and deformed when the lining tape 100 is wound, thereby enabling the structure of the load recording structure 10 to have better flexibility and bending resistance, and prolonging the service life.

In the present embodiment, as shown in fig. 4, the electrical relationship or signal relationship among the components in the liner 100 is substantially as follows: the flexible circuit board 310 is electrically connected to the battery 400, a controller (not shown) is disposed on and electrically connected to the flexible circuit board 310, and the flexible circuit board 310 is further electrically connected to the pressure sensor 200 to electrically connect the control assembly 300 and the pressure sensor 200. In addition, the induction coil 320 is connected to the controller and an external terminal through signals, so that signal interaction is realized. It can be understood that, after the pressure sensor 200 converts the sensed pressure into a resistance, the resistance is usually connected to the controller of the control assembly 300 through a connected resistance voltage divider circuit (not shown), so that the controller performs voltage acquisition and processing to obtain weight data, and stores the related data in a data storage area thereof, and when a user needs the weight sensor, the stored weight information of the user, such as weight and duration of weight, can be read through an external terminal.

In this embodiment, the induction coil 320 may preferably adopt an NFC antenna coil for passive near field communication, and the induction coil 320 does not need to be charged, thereby reducing the power consumption of the battery 400 and realizing a low power consumption design, so that the power requirement of the load recording structure 10 can be satisfied by adopting a common dry battery 400. In this case, for example, the user may use the mobile phone with the NFC function to perform the short-distance wireless communication with the control component 300 of the load recording structure 10 to obtain the load conditions (including the load weight and the load duration) of the user, store the data in the mobile phone, and transmit the data to the cloud for further data analysis and mining, and may also directly clear the historical data in the controller through the mobile phone, so on the one hand, the devices built in the load recording structure 10 may be reduced, and the use is convenient, and on the other hand, the long-term monitoring and recording of the load may be realized.

It should be noted that, in this embodiment, the controller may be a KG316T model controller 300, and of course, other models of controllers may also be used, which is not limited herein.
