Abstract
Description
Technical Field
[0001] This invention relates to the technical field of wearable electronic devices for animals, and more particularly to a chest and back device for animals that uses gallium arsenide solar cells to power functional modules in a chest and back wearing scenario. Background Technology
[0002] As is well known, wearable electronic devices for animals often integrate functions such as positioning, communication, lighting, or training. These devices are prone to tilting or rotating during animal movement, running, rolling, or other activities, resulting in unstable orientation of the upper surface of the wearable electronic device.
[0003] When animal wearable electronic devices integrate photovoltaic power supply and satellite positioning reception, the unstable posture of the wearable electronic devices will lead to fluctuations in photovoltaic light reception conditions and a decrease in the average light-receiving area. Furthermore, due to the limited light-receiving area available for photovoltaic installation when the wearable electronic devices are in use, as well as the limitations in device weight and volume, simply using photovoltaic devices with low output power per unit area or simply increasing the battery area is insufficient to meet the device's power supply requirements. Therefore, the energy acquisition stability and battery life of existing animal wearable electronic devices are poor.
[0004] Meanwhile, in existing wearable electronic devices for animals, a single-unit shell is usually used or multiple functional components are installed in a unified base structure or main unit structure, and then connected to the wearing strap through the base structure or main unit structure. Therefore, during the animal's running, jumping, turning and pitching movements, the curvature and deformation of its torso surface are significant. The centralized or large-volume rigid structure is prone to causing local pressure and non-fitting to the animal, resulting in decreased comfort and stress concentration.
[0005] Therefore, there is a need for an animal thoracolumbar apparatus to overcome one or more of the aforementioned defects. Summary of the Invention
[0006] The purpose of this invention is to provide an animal chest and back device that improves light reception, extends battery life, and provides a comfortable fit.
[0007] To achieve the above objectives, the animal chest and back device of the present invention includes a flexible chest and back base for fitting snugly onto the surface of an animal's torso, at least two functional modules spaced apart from each other, a flexible connecting portion disposed between two adjacent functional modules, and a solar cell for supplying power to the circuit components within the functional modules. The flexible chest and back base has a back facing upwards in the wearing state, a chest facing downwards in the wearing state, and front and rear portions for connecting the chest and back together. The rear portion, front portion, back, and chest together define a side opening for the animal's forelimbs to extend out of the flexible chest and back base. The rear portion, back, and chest together define a rear opening for the animal's torso to extend out of the flexible chest and back base from the rear. The front portion, back, and chest together define a front opening for the animal's torso to extend out of the flexible chest and back base from the front. The functional module is mounted on the back and faces the outer side of the back. The functional module contains circuit components. The flexible connection portion allows the relative angle of two adjacent functional modules to change in the wearing state to adapt to changes in the curvature of the animal's body surface. The solar cell is disposed on the surface of the functional module facing away from the back. The solar cell includes a gallium arsenide solar cell.
[0008] Compared to existing technologies, the design of the flexible chest and back substrate, which features a back facing upwards when worn, a chest facing downwards, and front and rear sections connecting the chest and back, with the rear, front, back, and chest jointly defining a side opening, a rear opening, and a front opening, ensures that the functional modules and their solar cells remain facing upwards during wear. This results in more stable light exposure, increases the effective working time of the solar cells, and enhances the usability and practicality of solar power supply during wear. Furthermore, the use of gallium arsenide solar cells allows for higher output power per unit area within a limited light-receiving area, enabling more effective energy input into the power supply system of the animal chest and back device, thereby improving its endurance. Additionally, the flexible connecting parts allow for angle changes between adjacent functional modules during wear to adapt to variations in the curvature of the animal's body surface, resulting in a comfortable fit and preventing stress concentration.

[0038] To illustrate the technical content and structural features of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.
[0039] Please see Figure 1 and Figure 2 The animal thoracolumbar device 100 of the present invention is designed to be worn on the surface of an animal's torso and to surround and conform to the surface of the animal's torso, so as to minimize the undesirable rotation of the animal thoracolumbar device 100 relative to the animal's torso surface in the circumferential direction. Furthermore, in combination with... Figures 4 to 6 The animal chest and back device 100 of the present invention includes a flexible chest and back base 10 for fitting snugly on the surface of an animal's torso, two functional modules 20 spaced apart from each other, a flexible connecting portion 30 disposed between two adjacent functional modules 20, and a solar cell 40 for powering the circuit assembly 21 mentioned below.
[0040] Among them, Yu Figure 1 In this design, the flexible thoracoback base 10 has a back 11 facing upwards in the wearing state (referring to the state where the flexible thoracoback base 10 is worn on the surface of the animal's torso), a chest 12 facing downwards in the wearing state, and a front side portion 13 and a rear side portion 14 for connecting the chest 12 and the back 11. The rear side portion 14, the front side portion 13, the back 11, and the chest 12 together define a lateral protrusion 15 for the animal's forelimbs to extend out of the flexible thoracoback base 10. Optionally, in... Figure 1In this example, the front side 13 and the rear side 14 are arranged opposite each other, one on the left and one on the right, so that there are two side protrusions 15, one on the left and the other on the right, to meet the needs of the animal's left forelimb and right forelimb extending out of the corresponding side protrusions 15 from the flexible thorax and back base 10. The rear side 14, back 11, and chest 12 together define a rear protrusion 16 for the animal's torso to extend from the rear into the flexible chest and back base 10, and the front side 13, back 11, and chest 12 together define a front protrusion 17 for the animal's torso to extend from the front into the flexible chest and back base 10. Therefore, when the flexible chest and back base 10 is worn, the animal's forelimbs extend from the side protrusion 15 into the flexible chest and back base 10, and the animal's torso extends from the rear protrusion 16 and the front protrusion 17 into the flexible chest and back base 10, respectively. This achieves the goal of preventing the flexible chest and back base 10 from rotating undesirably relative to the surface of the animal's torso in the circumferential direction, thereby keeping the back 11 of the flexible chest and back base 10 in a stable upward position and the chest 12 in a stable downward position, thus creating favorable conditions for improving light reception.
[0041] Meanwhile, the functional module 20 is mounted on the back 11, and the functional module 20 also faces the outer side 111 of the back 11 to meet the requirement that the functional module 20 is arranged facing upwards when worn; the functional module 20 contains a circuit component 21; optionally, in Figure 5 and Figure 6 In this example, circuit component 21 includes a satellite positioning module 211, which, combined with functional module 20, is arranged upwards when worn. This effectively improves the stability of satellite signal reception by the satellite positioning module 211. It is worth noting that although the case where circuit component 21 includes a satellite positioning module 211 has been described above, it is clear that, depending on actual needs, circuit component 21 can also include a wireless communication module, or even include both a satellite positioning module 211 and a wireless communication module. Therefore, this is not the case. Figure 5 and Figure 6 The above description is for illustrative purposes only; furthermore, the wireless communication module may include at least one of cellular communication, Bluetooth and Wi-Fi communication, and the satellite positioning module 211 is only one implementation of the positioning module, that is to say, the positioning module may be other types of positioning modules besides the satellite positioning module 211.
[0042] Furthermore, the flexible connection 30 allows for relative angular changes between adjacent functional modules 20 during the wearing state, for example, at... Figure 6In this process, the flexible connection 30 allows two adjacent functional modules 20 to move closer together and have a smaller included angle, or allows two functional modules 20 to move further apart and have a larger included angle, in order to adapt to changes in the curvature of the animal's body surface; alternatively, as an example, the flexible connection 30 may be an elastomer connector, a flexible sheet connector, a corrugated structure connector, a serpentine connector, or a fabric composite connector, so that by means of the folding, bending and automatic reset of the flexible connection 20, the two adjacent functional modules 20 can be rotated relative to each other, thereby achieving the purpose of changing the angle of the two adjacent functional modules 20.
[0043] And solar cell 40 (see Figure 1 A solar cell 40 is disposed on the surface 22 of the functional module 20, which faces away from the back 11, so that the solar cell 40 always faces upward (upward) when worn, thereby ensuring the stability of the solar cell 40 in receiving light. Furthermore, the solar cell 40 includes a gallium arsenide solar cell 41 to provide higher output power per unit area under the conditions of limited light-receiving area and weight of the animal chest harness 100 of the present invention, so that the energy obtained by solar energy can participate in the power supply system of the animal chest harness 100 of the present invention, thereby improving the endurance of the animal chest harness 100 of the present invention. Specifically, as an example, the gallium arsenide solar cell 41 is a multi-junction gallium arsenide solar cell, such as a double-junction, triple-junction, or more-junction gallium arsenide multi-junction cell structure, to further improve the output power per unit area, thereby making it more suitable for occasions with limited light-receiving area and weight; in addition, the multi-junction gallium arsenide solar cell includes at least two sub-cell junction layers with different band gaps to improve spectral utilization efficiency and further increase the output power per unit area. More specifically, see the description below.
[0044] like Figures 1 to 3 As shown, as an example, the flexible chest and back support 10 also has an opening and closing structure 18 for separating or joining the front portion 13. The opening and closing structure 18 can be, but is not limited to, a male / female clasp or Velcro, to improve the ease of wearing the animal chest and back support device 100 of the present invention. It should be noted that, although... Figure 1 and Figure 3 The opening and closing structure 18 is shown to separate or join the left front portion 13; obviously, depending on actual needs, the opening and closing structure 18 can also separate or join the right front portion 13; or, the opening and closing structure 18 can also separate or join the left and / or right rear portions 14, therefore not considered as such. Figure 1 and Figure 3 The above is the limit.
[0045] like Figure 7As shown, as an example, the end of the functional module 20 is provided with an end connection interface structure 23 for cooperating with the flexible connection part 30. Optionally, the end connection interface structure 23 is wrapped and connected to the flexible connection part 30 to ensure the reliability of the connection and sealing between the functional module 20 and the flexible connection part 30, thereby improving the waterproof, dustproof and impact resistance between the functional module 20 and the flexible connection part 30. Obviously, depending on actual needs, the end connection interface structure 23 can also be snapped or fitted with the flexible connection part 30. Furthermore, in Figure 7 In this example, functional module 20 has a connecting channel 24, and flexible connection part 30 has an electrical connection channel 31 that connects to the connecting channel 24. Electrical connection channel 31 has a conductive structure 32 for electrically connecting circuit components 21 in adjacent functional modules 20. Optionally, as an example, the conductive structure 32 can be a wire, a conductive component, or a flexible circuit board to meet the power and signal transmission between circuit components 21 in adjacent functional modules 20 and improve the reliability and consistency of wiring and electrical connections between functional modules 20. Furthermore, in Figure 7 As an example, the end connection interface structure 23 includes a convex annular platform 231 arranged around the communication channel 24 and connected to the flexible connection portion 30, so as to increase the coverage area between the functional module 20 and the flexible connection portion 30 by means of the convex annular platform 231; alternatively, in Figure 7 As an example, a concave annular groove 232 extending circumferentially from the convex annular platform 231 and connecting with the flexible connecting portion 30 is formed on the side wall of the convex annular platform 231, thereby further increasing the coverage area between the functional module 20 and the flexible connecting portion 30. Finally, in Figure 6 and Figure 7 As an example, each functional module 20 also includes an energy storage unit 25 for storing the electricity supplied by the solar cell 40, thereby further improving the endurance of the animal chest and back device 100 of the present invention; obviously, depending on actual needs, some of all functional modules 20 may also include energy storage units 25, therefore, it is not necessary to specify the energy storage unit 25. Figure 6 and Figure 7 The above is a limited description. It should be noted that the energy storage unit 25 can be, but is not limited to, a secondary battery; furthermore, although... Figure 7 The convex annular platform 231 and concave annular groove 232 shown are each annular rings that are open at both ends in the circumferential direction. Obviously, depending on actual needs, the convex annular platform 231 and concave annular groove 232 can also be designed as closed annular rings that are connected end to end in the circumferential direction. Therefore, it is not considered that... Figure 7 The above is the limit.
[0046] Combination Figures 5 to 10As an example, the animal thorax device 100 of the present invention also includes a flexible connecting strap 50 located between the back 11 and the functional module 20. In this case, a first perforation 113 and a second perforation 114 are provided on the back 11. Optionally, [the following is an example of a different device]. Figure 1 In this example, the first perforation 113 and the second perforation 114 are spaced apart, but this is not a limitation; the first end 51 of the flexible connecting strap 50 passes through the first perforation 113 through the back 11 and is fitted and connected to the inner side 112 of the back 11, and the second end 52 of the flexible connecting strap 50 passes through the second perforation 114 through the back 11 and is fitted and connected to the inner side 112 of the back 11; and each functional module 20 is provided with a winding structure 26 for the flexible connecting strap 50 to be wound around the position 53 between the first end 51 and the second end 52 to install each functional module 20 on the back 11; this design allows adjacent functional modules 20 to slide along the flexible connecting strap 50 as their relative angle changes adaptively according to the curvature of the animal's body surface, so that the back 11 will not be arched or laid down when adjacent functional modules 20 are close to each other or lie down, thus ensuring that the flexible thoracic and back base 10 remains in contact with the surface of the animal's torso. Specifically, in Figures 8 to 10 As an example, the functional module 20 also has a guide groove 27 facing the back 11. The guide groove 27 guides the functional module 20 to slide along the flexible connecting strip 50 during the change of the angle of the functional module 20. At this time, the flexible connecting strip 50 is located at position 53 between the first end 51 and the second end 52 in the guide groove 27, as shown in the figure. Figure 8 or Figure 9 As shown; the winding structure 26 spans the guide groove 27, and the winding structure 26 is also located on the end of the functional module 20 away from the flexible connection portion 30, for example, at Figure 10 In the design, the left-side winding structure 26 is located on the left end of the left functional module 20, and the right-side winding structure 26 is located on the right end of the right functional module 20. Therefore, by utilizing the design that "the winding structure 26 spans the guide groove 27 and is located on the end of the functional module 20 furthest from the flexible connecting portion 30, and the flexible connecting strip 50 is located at position 53 between the first end 51 and the second end 52 within the guide groove 27," the flexible connecting strip 50 more reliably connects the functional module 20 to the back 11 and effectively controls the functional module 20 to slide only along the flexible connecting strip 50 during angular changes. Furthermore, regarding... Figure 5 , Figure 6 , Figure 7 , Figure 9 and Figure 10In this example, in two adjacent functional modules 20, each functional module 20 protrudes towards the back 11 from its corresponding flexible connecting portion 30 (i.e., the flexible connecting portion 30 located between two adjacent functional modules 20), so that the two adjacent functional modules 20 and their corresponding flexible connecting portions 30 jointly define a notch 60. The notch 60 faces the position 53 of the flexible connecting band 50 located between the first end 51 and the second end 52. This design makes the surface 22 of the two adjacent functional modules 20 facing away from the back 11 of the flexible chest and back base 10 flush with the surface 33 of the flexible connecting portion 30 facing away from the back 11 of the flexible chest and back base 10, thereby making the animal chest and back device 100 of the present invention neater and more aesthetically pleasing. In addition, since the two adjacent functional modules 20 and their corresponding flexible connecting portions 30 jointly define the notch 60, the flexible connecting portion 30 can more easily and smoothly allow the two adjacent functional modules 20 to produce relative angular changes. Furthermore, in Figure 2 , Figure 5 , Figure 6 , Figure 9 and Figure 10 In this example, the first end 51 and the second end 52 of the flexible connecting strap 50 are detachably connected to the inner side 112 of the back 11 via a male-female buckle 70, facilitating the attachment and removal of the functional module 20 from the back 11. Obviously, depending on actual needs, the first end 51 and the second end 52 of the flexible connecting strap 50 can also be detachably connected to the inner side 112 of the back 11 via Velcro; or, the first end 51 or the second end 52 of the flexible connecting strap 50 can be connected to the inner side 112 of the back 11 via Velcro or a male-female buckle 70, therefore... Figure 2 , Figure 5 , Figure 6 , Figure 9 and Figure 10 The above is the limit.
[0047] like Figure 11As shown, as an example, the solar cell 40 also includes a perovskite solar cell 42 stacked on the gallium arsenide solar cell 41, so that the solar cell 40 forms a tandem battery structure of gallium arsenide and perovskite. This design can provide higher output power per unit area within a limited light-receiving area, so that the energy obtained by solar energy can participate more effectively in the power supply system of the animal chest and back device 100 of the present invention, further improving the endurance of the animal chest and back device 100 of the present invention. Specifically, as an example, the tandem battery structure adopts a two-terminal (2T) electrical connection method, that is, multiple sub-cell layers form a series structure in electrical connection to obtain a higher output voltage and improve the output power per unit area; obviously, according to actual needs, the tandem battery structure also adopts a four-terminal (4T) electrical connection method, that is, different sub-cell layers output independently, and are managed by the circuit component 21 or the energy management circuit for current collection, voltage regulation and / or charging management, so as to improve the energy acquisition effect under different spectrum and light-receiving conditions. It is worth noting that the solar cell 40 can be flexibly selected to include a perovskite solar cell 42 stacked on the gallium arsenide solar cell 41, depending on actual needs. That is, in some embodiments, the solar cell 40 can be designed not to include the perovskite solar cell 42.
[0048] Compared with the prior art, the flexible chest and back substrate 10 has a back 11 facing upward in the wearing state, a chest 12 facing downward in the wearing state, and a front side portion 13 and a rear side portion 14 for connecting the chest 12 and the back 11 together. The rear side portion 14, the front side portion 13, the back 11 and the chest 12 together define a side opening 15, the rear side portion 14, the back 11 and the chest 12 together define a rear opening 16, and the front side portion 13, the back 11 and the chest 12 together define a front opening 17. This design makes the functional module 20 and the functional module 20 more convenient. The solar cell 40 remains in an upward-facing position during wear, ensuring stable sunlight exposure and increasing its effective operating time. This enhances the usability and practicality of solar power supply during wear. Furthermore, the inclusion of a gallium arsenide solar cell 41 within the solar cell 40 provides higher output power per unit area within a limited light-receiving area. This allows the acquired energy to be more effectively integrated into the power supply system of the animal chest and back harness 100, thereby improving its endurance. Additionally, the flexible connection 30 allows for angular changes between adjacent functional modules 20 during wear, adapting to variations in the animal's body curvature, resulting in a comfortable fit and preventing stress concentration.
[0049] It should be noted that the flexible chest and back substrate 10 is made of fabric. Furthermore, although the attached figures show two functional modules 20, the number of functional modules 20 can obviously be three, four, or more depending on actual needs, and is not limited to what is shown in the figures. Additionally, although the attached figures show each functional module 20 equipped with a solar cell 40, it is obvious that some of the functional modules 20 can also be equipped with solar cells 40 depending on actual needs, and is not limited to what is shown in the figures.
[0050] The above description is merely a preferred embodiment of the present invention and should not be construed as limiting the scope of the invention. Therefore, any equivalent variations made in accordance with the claims of the present invention are within the scope of the present invention.
