Description

Technical Field

[0001] This application relates to the field of sensor technology, and more specifically, to a novel wearable sensor structure. Background Technology

[0002] With the development of sensor technology, especially the widespread use of wearable devices, it has become possible to automate and refine livestock behavior monitoring using accelerometers. An accelerometer is a device that measures acceleration and is typically used to detect the motion of an object. These sensors are usually installed on the neck, legs, or other body parts of livestock to help capture comprehensive movement information. By monitoring livestock movement patterns, farmers and veterinarians can detect abnormal behavior more promptly, allowing them to take appropriate measures to reduce disease transmission and improve farming efficiency.

[0003] Existing sensors of this type suffer from poor waterproofing and inadequate internal circuit protection, especially those with USB interfaces, where these challenges are particularly pronounced. While an external USB port allows for convenient downloading of data from the sensor's memory to a computer, it significantly reduces the sensor's structural protection, particularly its waterproofing.

[0004] In view of the above, this application is hereby submitted. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this application is to provide a novel wearable sensor structure with good waterproof performance, thereby solving the problem of poor waterproof performance of sensors.

[0006] One aspect of this application provides a novel wearable sensor structure, comprising: an upper housing and a lower housing, wherein the upper housing and the lower housing are threadedly connected.

[0007] The upper outer shell is provided with a groove, and a waterproof coil is provided in the groove;

[0008] The top of the lower outer casing is provided with a protrusion, which can be inserted into the groove and abut against the waterproof coil;

[0009] The upper outer shell has a first receiving cavity inside, and the inner sidewall of the upper outer shell is provided with a columnar structure located in the first receiving cavity for fixing and supporting the sensor board.

[0010] The upper part of the upper shell is also provided with a first arch structure protruding outward, and the upper part of the lower shell is provided with a second arch structure at a position corresponding to the first arch structure, for positioning and fixing the upper shell and the lower shell.

[0011] Furthermore, the cylindrical structure has multiple components, which are spaced apart on the inner peripheral wall of the upper housing, and the sensor circuit board is fixed to one end of the cylindrical structure;

[0012] The first receiving cavity, through the cylindrical structure, is used to house and fix the lithium battery.

[0013] Furthermore, one end of the cylindrical structure extends from the top inner wall of the upper outer shell towards the lower outer shell.

[0014] The extended end of the cylindrical structure has an opening, and the sensor board is fixed to the extended end of the cylindrical structure through the opening.

[0015] Furthermore, the groove is provided on the top inner wall of the upper housing.

[0016] Furthermore, the lower outer shell and the upper outer shell are cylindrical structures; the outer diameter of the upper outer shell is smaller than the inner diameter of the lower outer shell;

[0017] The upper outer peripheral wall of the upper outer shell is provided with external threads, and the upper inner peripheral wall of the lower outer shell is provided with internal threads.

[0018] The groove is located above the external thread, and the protrusion extends from the top of the lower housing toward the upper housing.

[0019] Furthermore, the top outer wall of the upper shell is an inwardly concave arc-shaped surface for fitting the wearing position;

[0020] The curved surface has outwardly extending fixing parts at both ends, which are symmetrically arranged relative to the first arched structure. The fixing parts have slender through holes for installing and fixing bandages.

[0021] Furthermore, the inner sidewall of the fixing part is provided with an annular rib coaxial with the cylindrical structure, and there is a gap between the annular rib and the outer wall of the upper shell to form the groove.

[0022] Furthermore, the inner diameter of the protrusion is the same as the inner diameter of the lower outer shell, and the outer diameter of the protrusion is smaller than the outer diameter of the lower outer shell.

[0023] Furthermore, the first arched structure and the second arched structure are respectively provided with a first threaded hole and a second threaded hole, which are used to align the first threaded hole and the second threaded hole after the upper outer shell and the lower outer shell are threadedly connected, and to fix the upper outer shell and the lower outer shell by screws.

[0024] Furthermore, the edges of both the upper and lower outer shells are chamfered.

[0025] Compared with the prior art, this application has at least one of the following beneficial effects:

[0026] (1) The wearable novel sensor structure of this application has good waterproof effect. It has good waterproof performance. The upper shell and the lower shell are tightly connected by threaded connection, which enhances the sealing of the sensor structure shell and ensures a firm connection between the two parts. The waterproof coil is precisely embedded in the groove of the upper shell, which can effectively prevent water from seeping into the sensor. This is especially important for the use of the sensor in humid or watery environments (such as pastures, rainy days, etc.), ensuring the long-term stable operation of the device in harsh environments and avoiding short circuits or equipment damage caused by water intrusion.

[0027] (2) The wearable sensor structure of this application has good waterproof effect. Its structure is more stable and reliable. The upper and lower shells of the sensor structure adopt an arched structure design. By overlapping the arched structures of the upper and lower shells, and with the addition of screws and nuts, the overall structural stability is greatly improved, the sensor's shock resistance during long-term use is enhanced, and the risk of shell deformation or loosening caused by external impact is effectively reduced. In addition, the use of threaded connection further improves the tensile and torsional resistance of the sensor structure shell, so that the sensor can maintain a good working state in various environments.

[0028] (3) The wearable sensor structure of this application has good waterproof effect and makes reasonable use of the internal space. The design of the internal space of the sensor has been carefully planned. Three columnar structures are specially set inside the upper shell. The columnar structures are not only used to fix the lithium battery, but also to provide support for the sensor circuit board. The internal space is effectively utilized, avoiding installation difficulties or loosening problems caused by insufficient space for the battery and circuit board. In addition, the position of the columnar structure has been optimized, which can ensure the stability and safety of the internal components without increasing the external size of the sensor, and reduce component displacement or poor contact caused by vibration.

[0029] (4) The wearable sensor structure of this application has good waterproof effect and is designed for livestock. In order to ensure that the sensor will not cause discomfort to the livestock during long-term wear, the upper shell is designed with an arc-shaped curved surface, which can naturally conform to the body curve of the livestock, reduce pressure and friction caused by improper fit, and reduce the risk of skin damage to the livestock during activity. Secondly, the uniform installation direction of the sensor is particularly important. The arched structure on the outside of the shell provides a basis for the wearing and installation of the strap and the sensor. The edge of the top of the shell is finely polished, making it softer during wear and avoiding potential injury to the livestock from sharp edges. The through hole design on both sides facilitates the installation of the strap. The sensor can be firmly fixed to the livestock through the strap, ensuring the stability of the sensor whether the livestock is walking, running or resting.

[0030] (5) The wearable novel sensor structure with good waterproof effect has improved safety and aesthetics through edge processing. The edge processing of the sensor shell not only takes into account the aesthetics of the device, but also pays special attention to safety. The corners of the upper and lower shells are chamfered and polished, which not only makes the appearance smoother and more beautiful, but also avoids the potential harm of sharp corners to users and livestock. The humanized design is particularly suitable for the scenario of livestock behavior monitoring, reducing the risk of cuts or wear caused by the unevenness of the sensor surface, and improving the overall user experience of the device.

[0040] The present application will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present application, but do not limit the present application in any way. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present application. These all fall within the protection scope of the present application.

[0041] Reference Figure 1 As shown, a wearable novel sensor structure according to an embodiment of this application includes an upper shell 8 and a lower shell 6, with the upper shell 8 and the lower shell 6 being threadedly connected; the upper shell 8 is provided with a groove 14, and a waterproof coil 19 is provided in the groove 14; the top of the lower shell 6 is provided with a protrusion 1, which can be inserted into the groove 14 and abut against the waterproof coil 19.

[0042] The upper outer shell 8 has a first receiving cavity 18 inside. The inner side wall of the upper outer shell 8 is provided with a columnar structure located in the first receiving cavity 18 for fixing and supporting the sensor board. The upper part of the upper outer shell 8 is also provided with an outwardly protruding first arched structure 11. The upper part of the lower outer shell 6 is provided with a second arched structure 3 at a position corresponding to the first arched structure 11 for positioning and fixing the upper outer shell 8 and the lower outer shell 6.

[0043] The upper outer shell 8 and the lower outer shell 6 are connected by threads, making the sensor structure more stable, facilitating user assembly and disassembly, and improving the maintainability and replaceability of the sensor. A waterproof coil 19 is provided in the groove 14 of the upper outer shell 8, and the protrusion 1 of the lower outer shell 6 can be inserted into the groove 14 to abut against the waterproof coil 19, effectively preventing moisture from seeping into the sensor from the connection between the upper and lower outer shells 6 in a humid environment, ensuring the normal operation of the sensor in a humid environment and extending the service life of the sensor. The first arched structure 11 of the upper outer shell 8 and the second arched structure 3 of the lower outer shell 6 correspond to each other and can be used to accurately position and fix the upper outer shell 8 and the lower outer shell 6, further improving the overall structural strength of the sensor, making the sensor more stable when worn and less likely to fall off or shift.

[0044] During assembly, firstly, the first arched structure 11 and the second arched structure 3 on the upper outer shell 8 and the lower outer shell 6 are aligned. Then, the upper outer shell 8 and the lower outer shell 6 are threadedly fixed together, with the first arched structure 11 corresponding to the second arched structure 3. Next, the waterproof coil 19 is placed on the groove 14 of the upper outer shell 8. Then, the protrusion 1 of the lower outer shell 6 is inserted into the groove 14 of the upper outer shell 8 during the sealing process and abuts against the waterproof coil 19, thereby compressing the waterproof coil 19 and improving the sealing and waterproof performance of the sensor structure. At the same time, the upper outer shell 8 has a first receiving cavity 18 inside, and the lower outer shell 6 has a second receiving cavity 7 inside. The inner wall of the first receiving cavity 18 of the upper outer shell 8 is provided with a columnar structure. The sensor is fixed in the sensor structure through the columnar structure, realizing the assembly of the sensor structure. At the same time, the above structure improves the waterproof effect of the sensor structure.

[0045] In some specific embodiments, there are multiple cylindrical structures, spaced apart on the inner peripheral wall of the upper housing 8, and the sensor board is fixed to one end of the cylindrical structure; the first receiving cavity 18 is used to receive and fix the lithium battery through the cylindrical structure.

[0046] By setting multiple columnar structures on the inner peripheral wall of the upper outer shell 8, the sensor circuit board can be supported and fixed. On the other hand, the multiple columnar structures change the space of the first receiving cavity 18, making it convenient to place the lithium battery that provides power to the sensor.

[0047] Specifically, one end of the cylindrical structure extends from the top inner wall of the upper outer shell 8 towards the lower outer shell 6. The extended end of the cylindrical structure has an opening, through which the sensor board is fixed to the extended end of the cylindrical structure.

[0048] The cylindrical structure extends within the first receiving cavity 18, which increases the strength of the outer shell 8 on the sensor structure and makes it easier to restrict the movement of the lithium battery. An opening is provided at the extended end to facilitate fixing the sensor board to the cylindrical structure with screws, thereby improving the stability of the sensor board within the sensor structure.

[0049] For example, there are three cylindrical structures, including a first cylindrical structure 15, a second cylindrical structure 16, and a third cylindrical structure 17, which are spaced apart within the receiving cavity. These three structures are arranged inside the upper outer shell 8 to provide reliable support and fixation for the sensor circuit board. Multiple angles of the sensor circuit board are fixed to the first cylindrical structure 15, the second cylindrical structure 16, and the third cylindrical structure 17 with screws, ensuring that the circuit board will not shift due to vibration or external force during sensor use. Simultaneously, the first receiving cavity 18 reserved between the cylindrical structures is used to house the lithium battery. This not only makes reasonable use of the internal space but also further improves the stability and safety of the sensor's internal structure by ensuring that the back of the lithium battery fits tightly against the inner side of the upper outer shell 8.

[0050] During the installation process, the lithium battery is first placed in the first receiving cavity 18 between the cylindrical structures, ensuring that the back of the battery is fully fitted against the internal structure of the upper housing 8. The battery is then fixed between the first cylindrical structure 15, the second cylindrical structure 16, and the third cylindrical structure 17 to prevent it from loosening or shifting inside the device. Next, the sensor circuit board is placed on the first cylindrical structure 15, the second cylindrical structure 16, and the third cylindrical structure 17 inside the upper housing 8 according to their corresponding positions, and the circuit board is fixed on them with screws to ensure the stability of the circuit board during normal use. Finally, the lower housing 6 is aligned with the upper housing 8 by threads and then tightly connected by rotation. At this time, the protrusion 1 at the upper end of the lower housing 6 will naturally abut against the groove 14 of the upper housing 8, causing appropriate compression of the waterproof coil 19 preset in the groove 14, achieving an effective waterproof seal and ensuring that the sensor can still operate normally in humid or harsh environments.

[0051] After the lower outer shell 6 is screwed tightly to the upper outer shell 8, there is still a certain space on its inner side that can accommodate the sensor circuit board with the USB port.

[0052] In some specific embodiments, the groove 14 is provided on the top inner sidewall of the upper housing 8.

[0053] By setting the groove 14 on the top inner wall of the upper housing 8, it makes the threaded connection with the lower housing 6 tighter, thus achieving a sealing effect. The top inner wall of the upper housing 8 is the side wall of the upper housing 8 that is close to the lower housing 6.

[0054] In some specific embodiments, the lower outer shell 6 and the upper outer shell 8 are cylindrical structures; the outer diameter of the upper outer shell 8 is smaller than the inner diameter of the lower outer shell 6; the upper outer peripheral wall of the upper outer shell 8 is provided with an external thread 13, and the upper inner peripheral wall of the lower outer shell 6 is provided with an internal thread 2; the groove 14 is located above the external thread 13, and the protrusion 1 extends from the top of the lower outer shell 6 towards the upper outer shell 8.

[0055] By arranging the upper outer shell 8 and the lower outer shell 6 into cylindrical structures, and setting the outer diameter of the upper outer shell 8 to be smaller than the inner diameter of the lower outer shell 6, the sensor structure adopts a rotating threaded shell fixing method. An external thread 13 is provided on the upper outer peripheral wall of the upper outer shell 8, and an internal thread 2 is provided on the upper inner peripheral wall of the lower outer shell 6, achieving a stable connection between the two, making assembly and disassembly more convenient. Furthermore, the first arched structure 11 and the second arched structure 3 on the upper outer shell 8 and the lower outer shell 6 serve to fix and position them, further improving the stability of the connection.

[0056] The inner diameter of protrusion 1 is the same as the inner diameter of the lower outer shell 6, and the outer diameter of protrusion 1 is smaller than the outer diameter of the lower outer shell 6.

[0057] Specifically, the protrusion 1 extends upward from the top of the lower housing 6. By making the inner diameter of the protrusion 1 the same as the inner diameter of the lower housing 6 and the outer diameter of the protrusion 1 smaller than the outer diameter of the lower housing 6, it can be better inserted into the groove 14 in the upper housing 8 during assembly to compress the waterproof coil 19.

[0058] Specifically, the first arched structure 11 and the second arched structure 3 are respectively provided with a first threaded hole 12 and a second threaded hole 4, which are used to align the first threaded hole 12 with the second threaded hole 4 after the upper outer shell 8 and the lower outer shell 6 are threadedly connected, and to fix the upper outer shell 8 and the lower outer shell 6 by screws.

[0059] The sensor structure adopts an upper outer shell 8 and a lower outer shell 6. The first arched structure 11 and the second arched structure 3 are provided with a first threaded hole 12 and a second threaded hole 4. During assembly, these holes serve to fix and position the sensor. The first arched structure 11 of the upper outer shell 8 and the second arched structure 3 of the lower outer shell 6 can be fixed with screws, which enhances the overall stability of the sensor structure. This allows the sensor to maintain good vibration resistance when facing changes in the external environment and livestock activities, and effectively extends the service life of the equipment.

[0060] During the installation and arrangement of sensors, the first arch structure 11 and the second arch structure 3 can provide position references.

[0061] In some specific embodiments, the top outer wall of the upper outer shell 8 is an inwardly concave arc-shaped surface for fitting the wearing position; the two ends of the arc-shaped surface are provided with outwardly extending fixing parts, which are symmetrically arranged relative to the first arch structure 11, and the fixing parts are provided with slender through holes for installing and fixing the bandage.

[0062] By setting the top outer wall of the upper outer shell 8 as an inwardly concave arc surface and polishing the edges of the upper outer shell 8, it can better fit the installation part of the livestock. Secondly, there are outwardly extending fixing parts at both ends of the arc surface on the top of the upper outer shell 8, so that the contact surface between the top outer wall of the upper outer shell 8 and the installation part of the livestock is wider. At the same time, there are slender through holes on the fixing parts, including a first through hole 9 and a second through hole 10, which are respectively set on the fixing parts. The straps can be installed through the first through hole 9 and the second through hole 10, and the assembled sensor can be fixed to the target livestock by the straps to prevent it from falling off during use.

[0063] Specifically, the top of the upper outer shell 8 is designed with a concave arc shape. This design takes into account the natural curves of the animal's body surface, allowing it to better conform to the animal's body parts (mainly the neck and legs), thereby reducing discomfort caused to the animal when wearing the sensor. To ensure that the device can be securely fixed to the animal, narrow through holes are specially opened on both sides of the top of the upper outer shell 8. These through holes are used to pass through the straps, allowing the sensor to be firmly attached to the animal, ensuring the stability of the device whether it is stationary or in motion.

[0064] Specifically, the inner wall of the fixing part is provided with an annular rib coaxial with the cylindrical structure, and there is a gap between the annular rib and the outer wall of the upper shell 8 to form a groove 14.

[0065] By setting an annular rib on the outer wall of the cylindrical structure, a certain distance is made between it and the outer peripheral wall of the upper shell 8, forming a groove 14, which improves the stability of the assembly and facilitates the cooperation with the protrusion 1 of the lower shell 6.

[0066] Specifically, the edges of both the upper outer shell 8 and the lower outer shell 6 are chamfered.

[0067] By using a chamfered edge structure on the upper shell 8 and the lower shell 6, and after fine polishing, the wearer is made more comfortable during wear, avoiding potential harm to livestock from sharp edges. The through-hole design on both sides facilitates the installation of the straps. The straps can securely fix the sensor structure to the livestock, ensuring the stability of the sensor whether the livestock is walking, running, or resting.

[0068] Using the aforementioned novel wearable sensor structure, researchers in a research project aimed at improving dairy cow welfare and productivity collected behavioral data from cows using accelerometers. These sensors, secured with bandages to the cows' necks and right forelegs, recorded triaxial acceleration data in real time at a specific frequency, continuously monitoring the cows' movement and behavioral status. By precisely analyzing this data, researchers were able to identify various daily behaviors of the cows, including feeding, rumination, standing, walking, and lying down. Each behavior has a specific behavioral data pattern, which researchers used to develop behavioral recognition algorithms for fine-grained monitoring of the cows' daily activities. The implementation of this system helps improve the efficiency of dairy cow welfare management, reduce disease risk, and optimize dairy cow productivity.
