Description

Technical Field

[0001] This invention belongs to the technical field of animal wearable devices, specifically an animal wearable device with a load-bearing, circumferential, and dual local vibration transmission structure. Background Technology

[0002] During the wearing, adjustment, and movement of animal collars and other wearable devices, the straps are subjected to mechanical forces such as tension, bending, swinging, and friction with external objects. If the piezoelectric sensor is placed directly on the main load-bearing path of the strap, the deformation caused by the force on the strap will act on the piezoelectric sensor together with the minute mechanical vibrations of the animal's body surface, so that the piezoelectric output simultaneously includes tensile, bending, and impact loads unrelated to vital signs.

[0003] Existing wearable animal devices utilize piezoelectric elements or flexible piezoelectric films to sense mechanical vibrations in the animal's neck and use the resulting signals for vital sign analysis such as heart rate and respiration. These products typically mount the piezoelectric element near the strap, shell, or surface contact, and may also incorporate contact protrusions, elastic layers, or mounting brackets. However, this arrangement causes the actual sensing area to exceed the effective sensing area. Impacts, friction, and significant bending experienced by the distal strap are converted into piezoelectric output, resulting in sensing errors. Simply changing the piezoelectric material, adding soft adhesive, or simply using two piezoelectric elements does not directly solve the problem of the main tensile force of the strap being transmitted to the piezoelectric element along the mounting structure, causing errors. Therefore, there is a need to design a wearable device that does not rely on PVDF materials or improved sensor calculation functions, but rather adjusts the force-bearing method of the piezoelectric element within the device to reduce or even eliminate irrelevant external force inputs. Summary of the Invention

[0004] The purpose of this invention is to provide an animal wearable device with a load-bearing bypass and dual local vibration transmission structure, which has a reasonable load-bearing method, reduces interference input, retains effective sensing, and reduces detection error.

[0005] To achieve the above objectives, the present invention provides the following technical solution: an animal wearable device with a load-bearing bypass and dual local vibration transmission structure, comprising a main body housing; a circuit board is disposed inside the main body housing, and load-bearing connection positions are disposed on both sides of the main body housing; a first sensing component and a second sensing component are inserted into the bottom of the main body housing, and a local clamping area is formed on the inner side of the animal's body surface.

[0006] Furthermore, the load-bearing connection position is connected to the first belt body and the second belt body; the load-bearing connection position is located on both sides of the outer side of the main body housing.

[0007] Furthermore, the main unit housing has an insertion interface on the side facing the animal's body surface.

[0008] Furthermore, one end of the first sensing component and the second sensing component are inserted into the connector and connected to the circuit board.

[0009] Furthermore, the first sensing component and the second sensing component each include an upper limiting and fixing layer and a lower flexible contact layer; a piezoelectric film is disposed between the upper limiting and fixing layer and the lower flexible contact layer.

[0010] Furthermore, the upper limiting and fixing layer and the lower flexible contact layer are made of rubber or silicone material; the lower flexible contact layer has contact protrusions on the side facing the animal's body surface.

[0011] Furthermore, an adhesive layer is provided between the piezoelectric film and the lower flexible contact layer.

[0012] Furthermore, the first sensing component and the second sensing component respectively include a piezoelectric film and a lower flexible contact layer.

[0013] Furthermore, the ends of the first sensing component and the second sensing component are provided with connecting buckles for the first belt body and the second belt body to pass through.

[0014] The present invention has the following advantages: In the prior art, the piezoelectric element extends along a large area of ​​the belt or is directly located in the tensile link between the two belts. The deformation caused by fastening, tension adjustment, and belt bending directly acts on the piezoelectric element. In the present invention, the main housing is provided with first and second belts on both sides, which are connected to the relative load-bearing positions of the main housing via load-bearing connections. The first and second sensing components are independent of the main load-bearing paths of the first and second belts. The main load generated by the collar during fastening, tension adjustment, and traction is transmitted between the first belt, the first load-bearing connection, the main housing, the second load-bearing connection, and the second belt. The first and second sensing components do not bear the main tensile load of the belt, therefore, they will not receive invalid electrical signal input, thus improving their detection accuracy.

[0015] Meanwhile, in existing technologies, if two local contact points share a single bridging membrane or lack independent fixed areas, local deformation may be transmitted along the membrane, which is not conducive to forming two distinguishable acquisition inputs. In this invention, the first and second sensing components are independent of each other, and can form independent acquisition at different contact points, reducing mutual interference.

[0016] Finally, during use, the first and second sensing components are held on the animal's body surface by the first and second straps, forming a relatively stable contact form; thus avoiding changes in vibration transmission conditions due to wear displacement, hair, or local curvature changes.

Detailed Implementation

[0023] To make the above-mentioned objects, features and advantages of the present invention more readily understood, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0024] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0025] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places throughout this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0026] Example 1 See Figures 1-3 An animal wearable device with a load-bearing bypass and dual local vibration transmission structure includes a main body housing 1; a circuit board is provided inside the main body housing 1, and load-bearing connection positions 2 are provided on both sides of the main body housing 1; a first sensing component 3 and a second sensing component 4 are inserted into the bottom of the main body housing 1, and a local clamping area is formed on the inner side of the animal's body surface.

[0027] Furthermore, the load-bearing connection 2 is connected to the first belt and the second belt; the load-bearing connection 2 is located on both sides of the outer side of the main housing 1.

[0028] Furthermore, the main unit housing 1 has an insertion interface 8 on the side facing the animal's body surface.

[0029] Furthermore, one end of the first sensing component and the second sensing component are inserted into the connector 8 and connected to the circuit board.

[0030] The load-bearing connection 2 connects the first and second belts to the main housing 1. The two load-bearing connection points 2 and the belts are located outside the two local piezoelectric sensing components, so that the wearing tensile load is not transferred to the first and second sensing components.

[0031] The aforementioned load-bearing bypass relationship is defined by the connection positions and force relationships between the components, and does not depend on making the piezoelectric film softer or simply adding cushioning material. Even if the structural layers in the two clamping areas are attached to each other, the two piezoelectric films do not participate in the main load-bearing connection between the two sides of the belt.

[0032] Furthermore, the first sensing component 3 and the second sensing component 4 respectively include an upper limiting and fixing layer 5 and a lower flexible contact layer 6; a piezoelectric film 7 is disposed between the upper limiting and fixing layer 5 and the lower flexible contact layer 6.

[0033] Furthermore, the upper limiting and fixing layer 5 and the lower flexible contact layer 6 are made of rubber or silicone material; the lower flexible contact layer 6 has a contact protrusion 6-1 on the side facing the animal's body surface.

[0034] Furthermore, an adhesive layer is also provided between the piezoelectric film 7 and the lower flexible contact layer 6.

[0035] The upper limiting and fixing layer 5 restricts the two piezoelectric films from detaching from the animal's body surface; the lower flexible contact layer 6 is respectively attached to the animal's body surface side of the piezoelectric film, and contact protrusions 6-1 are provided at two local positions. The upper and lower layers can be made of rubber or silicone materials, and the position of the film is maintained by the closure relationship.

[0036] The minute mechanical vibrations generated on the animal's body surface, such as heartbeats and respiration, are transmitted to the piezoelectric membrane via contact protrusions at two local locations and the underlying flexible contact layer. The two membranes are separated from each other, so that each mechanical input is mainly formed by the corresponding local contact location and is confined to the vicinity of the host.

[0037] Preferably, in the actual implementation, one piezoelectric film employs a higher nominal sensitivity and is directly closed and pressed together by the upper and lower structural members; the other piezoelectric film employs a lower nominal sensitivity and an adhesive layer is added in the corresponding pressing area. This adhesive layer can be located on one side of the film and can be a continuous layer, a local layer, or discrete adhesive dots. Different sensitivities and different coupling methods are used to form different mechanical response ranges, but do not replace the load-bearing bypass and dual local vibration transmission relationships.

[0038] The electrical connection terminals of the first and second piezoelectric films are respectively led out and connected to independent signal conditioning channels in the host.

[0039] Furthermore, the ends of the first sensing component 3 and the second sensing component 4 are provided with connecting buckles 9 through which the first belt and the second belt pass.

[0040] Working principle: The animal wearable device of the present invention includes a main body housing, a first belt, a second belt, a load-bearing connection 2, a first sensing component 3, and a second sensing component 4. The load-bearing connection 2 is located on opposite sides of the main body housing and is connected to the first belt and the second belt respectively; two local piezoelectric sensing components are disposed on the side of the main body housing 1 facing the animal's body surface.

[0041] The first and second strips form separate first and second clamping areas on both sides of the main unit. The first sensing component 3 is clamped within the first clamping area, and the second sensing component 4 is clamped within the second clamping area. The two piezoelectric films are separate films with independent electrical connection terminals, not connected by a continuous piezoelectric material. The lower flexible contact layer 6 has contact portions facing the animal's body surface in both clamping areas.

[0042] The first sensing component 3 and the second sensing component 4 extend locally from a position near the main housing 1 to their respective sides. Their effective sensing areas are limited to the vicinity of the main housing and do not extend to the distal fastening or length adjustment areas of the first and second belts. Thus, the piezoelectric films 7 within the first sensing component 3 and the second sensing component 4 correspond to two local contact positions, which avoids directly converting large bends at the distal ends of the belts into piezoelectric output, thus preventing detection errors.

[0043] During assembly, the first and second straps are first fixed to the load-bearing connection positions 2 on both sides of the main housing 1 to establish the main load-bearing channel of the wearable device. Then, the first sensing component 3 and the second sensing component 4 are respectively arranged in the first and second clamping areas on both sides of the main housing 1.

[0044] Preferably, the first clamping area directly closes and presses the piezoelectric membrane through the upper and lower structural components; the second clamping area is closed after an adhesive layer is applied between the piezoelectric membrane and the corresponding structural component. The contact protrusions 6-1 of the lower flexible contact layer 6 face the animal's body surface, and the upper limiting and fixing layer restricts the movement or disengagement of the two membranes towards the host. Both clamping areas are located near the host and do not extend to the fastening and adjustment area of ​​the distal strap.

[0045] The two electrical connection terminals are respectively connected to the circuit board inside the main housing 1. When the assembly is completed, the first belt and the second belt bear the main tensile load on both sides, and the two local piezoelectric sensing components maintain the corresponding position of contact and body surface, but neither of them bears the main tensile load across the two belts.

[0046] Example 2 See Figure 4 Furthermore, the first sensing component 3 and the second sensing component 4 respectively include a piezoelectric film 7 and a lower flexible contact layer 6.

[0047] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
