Description

Technical Field

[0001] This application relates to the technical field of duty equipment, and more particularly to a multifunctional vest. Background Technology

[0002] Currently, in scenarios such as traffic duty, users are required to wear vests with reflective and identifiable markings to facilitate duty operations, alert pedestrians, and identify themselves. However, duty locations are often outdoors, experiencing extreme temperatures in winter and summer, and since duty vests need to be worn as outerwear, they require high functional standards.

[0003] In existing technologies, such as the published patent CN201620567256.5, a multi-functional photovoltaic duty vest for both police and civilian use is provided. This vest integrates photovoltaic modules, temperature sensors, and semiconductor cooling elements, enabling temperature monitoring and adjustment, autonomous power generation, and energy storage, thus possessing high practicality. However, the photovoltaic modules used in existing technologies are often specially designed photovoltaic panels, rigidly installed on multiple surfaces of the vest, requiring avoidance of reflective strips. Furthermore, due to limitations in the vest's material area and the specific shape of the photovoltaic modules, while autonomous power generation and energy storage are possible, the power output is insufficient to meet the power needs of electrical equipment, resulting in a poor user experience.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this application, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] One of the technical problems this application aims to solve is that, currently, the fixed installation of photovoltaic modules in vests that integrate photovoltaic modules is limited by the reflective strips and the material area of ​​the vest, resulting in a small power generation that cannot meet the power demand of electrical equipment.

[0006] To address the aforementioned technical problems, this application provides a multifunctional vest, which mainly includes: a vest body, a photovoltaic module, and functional components. The outer layer of the vest body is provided with a plurality of first reflective elements; the photovoltaic module includes a first photovoltaic panel and a second photovoltaic panel that are movably connected to each other, the first photovoltaic panel being disposed on the outer layer connected between adjacent first reflective elements, and the second photovoltaic panel being stacked with the first photovoltaic panel; the functional components include an energy storage component and a plurality of functional components that are electrically connected, and both the first photovoltaic panel and the second photovoltaic panel are electrically connected to the energy storage component.

[0007] In some embodiments, the plurality of functional components include at least one of a temperature control component, a lighting component, and a communication component.

[0008] In some embodiments, the temperature control component is disposed in the inner layer of the vest body, electrically connected to the energy storage component, and is made of semiconductor material.

[0009] In some embodiments, the illumination component is disposed on the outer layer and includes one or more LED beads, all of which are electrically connected to the energy storage component.

[0010] In some embodiments, the communication component includes at least one of a wireless communication module, a Bluetooth module, and a positioning module.

[0011] In some embodiments, both the first photovoltaic panel and the second photovoltaic panel are flexible photovoltaic elements. When the second photovoltaic panel is de-stacked from the first photovoltaic panel, the projection of the second photovoltaic panel along the direction perpendicular to the outer layer partially overlaps with the first reflector.

[0012] In some embodiments, when stacked, the side of the first photovoltaic panel away from the outer layer is the light-receiving surface, the side of the second photovoltaic panel facing the first photovoltaic panel is the light-receiving surface, and the side of the second photovoltaic panel away from the first photovoltaic panel is the light-receiving surface or is provided with a second reflector.

[0013] In some embodiments, a connector is provided on the side of the second photovoltaic panel facing away from the first photovoltaic panel, and a connection structure is provided at the corresponding position on the outer layer. The connector and the connection structure have a connected state and a separated state.

[0014] In some embodiments, a flexible connector is provided between the first photovoltaic panel and the second photovoltaic panel, and the flexible connector is electrically connected to the first photovoltaic panel and the second photovoltaic panel respectively.

[0015] In some embodiments, a rotating connector and a flexible circuit are provided between the first photovoltaic panel and the second photovoltaic panel, and the flexible circuit is electrically connected to the first photovoltaic panel and the second photovoltaic panel respectively.

[0016] The above technical solution provides a multifunctional vest, which mainly includes: a vest body, photovoltaic modules, and functional components. The outer layer of the vest body is provided with multiple first reflective elements. The photovoltaic module includes a first photovoltaic panel and a second photovoltaic panel that are movably connected to each other. The first photovoltaic panel is disposed on the outer layer connected between adjacent first reflective elements, and the second photovoltaic panel is stacked with the first photovoltaic panel. The functional components include an energy storage component and multiple functional components that are electrically connected. Both the first and second photovoltaic panels are electrically connected to the energy storage component. The first and second photovoltaic panels, which are movably connected and stacked, can be opened or closed according to actual needs. For example, when there is sufficient sunlight, the photovoltaic module can be opened to generate electricity. At night, when no power generation is needed, the first and second photovoltaic panels can be stacked to avoid blocking the first reflective elements and to utilize the electricity stored during the day. Because the effective area of ​​the photovoltaic module in the above-mentioned multifunctional vest is not limited by the reflective strips and the material area of ​​the vest, it has a large power generation capacity, thereby ensuring the battery's energy storage capacity. Example 1 effectively solves the problem that the fixed installation of photovoltaic modules in vests that integrate photovoltaic modules is limited by the reflective strips and the material area of ​​the vest, resulting in a small power generation that cannot meet the power demand of electrical equipment.

[0035] Example 1:

[0036] like Figure 1 and Figure 2As shown in Embodiment 1 of this application, a multifunctional vest is provided, which mainly includes: a vest body 10, a photovoltaic module 20, and a functional component 30. The outer layer 11 of the vest body 10 is provided with multiple first reflective elements 12. The photovoltaic module 20 includes a first photovoltaic panel 21 and a second photovoltaic panel 22 that are movably connected to each other. The first photovoltaic panel 21 is disposed on the outer layer 11 between adjacent first reflective elements 12, and the second photovoltaic panel 22 is stacked with the first photovoltaic panel 21. The functional component 30 includes an energy storage component 31 and multiple functional components 32 that are electrically connected. Both the first photovoltaic panel 21 and the second photovoltaic panel 22 are electrically connected to the energy storage component 31. The first photovoltaic panel 21 and the second photovoltaic panel 22, which are movably connected to each other and stacked, can be opened or closed as needed to increase power generation.

[0037] Understandably, compared to traditional vests, in this embodiment, the first photovoltaic panel 21 is mounted on the outer layer 11, and the second photovoltaic panel 22, relying on the position of the first photovoltaic panel 21, can be unfolded and folded to increase its light-receiving area as needed, thereby increasing power generation. For example, during daytime duty, when there is ample sunlight, it is suitable for power generation and storage. At this time, the photovoltaic module 20 is turned on, allowing the first photovoltaic panel 21 and the second photovoltaic panel 22 to receive sunlight and generate electricity simultaneously. Even under sufficient sunlight, it will not affect the view, as the line of sight is relatively wide and can see far. Even if part of the first reflective element 12 is blocked, it will not affect the purpose of allowing pedestrians to see.

[0038] At night, when there is no sunlight and no need to generate electricity, the first photovoltaic panel 21 and the second photovoltaic panel 22 can be stacked. This avoids blocking the first reflector 12, provides more warning areas for display, and can also use the electricity stored during the day. When using the functional component 30, there will be no problem of insufficient power.

[0039] Because the effective area of ​​the photovoltaic module 20 in the aforementioned multifunctional vest is not limited by the reflective strips and the material area of ​​the vest, it has a large power generation capacity, thereby ensuring the battery's energy storage capacity. Example 1 effectively solves the problem that in current vests integrating photovoltaic modules, the fixed installation of the photovoltaic modules is limited by the reflective strips and the material area of ​​the vest, resulting in low power generation that cannot meet the power demands of electrical equipment.

[0040] like Figure 1As shown, in the technical solution of Embodiment 1, the multiple functional components 32 include at least one of a temperature control component 321, a lighting component 322, and a communication component 323. The temperature control component 321 can adapt to different seasons and weather conditions. When the temperature is low, it can directly heat the body to maintain body temperature during outdoor work. When the weather is hot, it can cool the body to maintain a suitable surface temperature, providing good outdoor working conditions. The temperature control component 321 is powered by an energy storage component 31, enabling both cooling and heating, providing coolness in hot weather and warmth in cold winter.

[0041] The illumination component 322 can be used for duty in conditions of poor visibility, such as nighttime duty or duty in foggy weather. Specifically, it can be a fog light or other beam of light with strong penetrating power and illumination. It can effectively increase the user's safety. The illumination component 322 is powered by the energy storage component 31.

[0042] The communication component 323 is used to provide communication and remote control functions, and the specific power supply is provided by the energy storage component 31.

[0043] like Figure 2 As shown, in the technical solution of Embodiment 1, the temperature control component 321 is disposed in the inner layer 13 of the vest body 10, electrically connected to the energy storage component 31, and is made of semiconductor material.

[0044] Semiconductor materials offer significant advantages in temperature control. For example, thermoelectric modules can be constructed using P-type and N-type semiconductor materials. When current flows through these modules, heat is absorbed at one end and released at the other. This phenomenon is called the Peltier effect, and by utilizing this principle, heating or cooling can be achieved by changing the direction of the current. Therefore, using this material in vests allows for the regulation of the vest's internal temperature as needed.

[0045] Furthermore, such as Figure 2 As shown, in the technical solution of Embodiment 1, the temperature control component 321 is generally arranged to cover the torso, which can provide the user with more efficient temperature control and experience in the core part of the torso.

[0046] In the technical solution of Embodiment 1 (not shown in the figure), the illumination component 322 is disposed on the outer layer 11 and includes one or more LED beads, all of which are electrically connected to the energy storage component 31. Using LED lights has advantages such as energy efficiency, long lifespan, environmental friendliness, fast response speed, rich colors, small size, and good shock resistance. Suitable for multifunctional vests, the energy storage component 31 can provide stable power output. Especially in foggy applications, LED lights exhibit characteristics such as strong penetration, rapid lighting, low energy consumption, directional light emission, and high safety, providing users with a safer user experience.

[0047] like Figure 1 As shown, in the technical solution of Embodiment 1, the communication component 323 includes at least one of a wireless communication module, a Bluetooth module, and a positioning module. The wireless communication module can specifically be a walkie-talkie, mobile phone, etc., and can communicate via a Bluetooth module or a wireless network module. The positioning module can be used for rapid location tracking, facilitating the immediate retrieval of the user.

[0048] The above-mentioned functional components 32 can effectively meet the needs of use. In some special scenarios, such as when traffic police use them, they can be directly connected to a remote terminal for remote control and communication, providing immediate communication.

[0049] like Figure 1 and Figure 2 As shown, in the technical solution of Embodiment 1 of this application, the vest body 10 is also provided with a name tag position 14 and an exhaust hole 15. The name tag position 14 can be Velcro for attaching name tags, and the exhaust hole 15 is used for internal heat dissipation, specifically for installing a fan, etc.

[0050] Example 2:

[0051] like Figure 3 As shown, in the technical solution of Embodiment 2 of this application, a multifunctional vest is provided based on the technical solution of Embodiment 1. The further improvement is that the first photovoltaic panel 21 and the second photovoltaic panel 22 are both flexible photovoltaic elements. When the second photovoltaic panel 22 is de-stacked from the first photovoltaic panel 21, the projection of the second photovoltaic panel 22 along the direction perpendicular to the outer layer 11 partially overlaps with the first reflector 12.

[0052] Flexible photovoltaic elements offer advantages such as lightweight, flexibility, portability, strong impact resistance, easy installation, wide application, reduced requirements for installation surfaces, and customizability. They can be applied to the outer layer 11 of uneven vest bodies 10, and during stacking, they can be adapted to different shapes of first photovoltaic panels 21 and second photovoltaic panels 22 through flexible deformation, making operation more convenient and disassembly and assembly easier.

[0053] For example, the first photovoltaic panel 21 and the second photovoltaic panel 22 at the shoulder position require a large curvature. Traditional photovoltaic panels are difficult to flip, but the flexible first photovoltaic panel 21 and the second photovoltaic panel 22 can be stacked, increasing the effective utilization area of ​​the first photovoltaic panel 21 and the second photovoltaic panel 22.

[0054] The projection of the second photovoltaic panel 22 along the direction perpendicular to the outer layer 11 partially overlaps with the first reflector 12. This arrangement ensures that the second photovoltaic panel 22 does not completely cover the first reflector 12 when it is unfolded, giving the first reflector 12 a good visual effect and effectively avoiding safety issues.

[0055] Understandably, in order to increase the effective light-receiving surface area, the second photovoltaic panel 22 is not limited to one, but can be multiple, as long as the weight of the multi-functional vest and the user's load capacity are taken into account.

[0056] Furthermore, such as Figure 3 As shown in Embodiment 2 of this application, in the stacked state, the side of the first photovoltaic panel 21 away from the outer layer 11 is the light-receiving surface, and the side of the second photovoltaic panel 22 away from the first photovoltaic panel 21 is provided with a second reflector 23. The provision of the second reflector 23 enables the multifunctional vest in Embodiment 2 to increase the effective area of ​​the reflector for warning purposes when the second photovoltaic panel 22 is not in use, thus providing safer and more reliable duty conditions.

[0057] Example 3:

[0058] like Figure 4 and Figure 5 As shown, in the technical solution of Embodiment 3 of this application, a multifunctional vest is provided based on the technical solution of Embodiment 1. The difference between the vest and Embodiment 2 is that the side of the second photovoltaic panel 22 facing the first photovoltaic panel 21 is the light-receiving side, and the side of the second photovoltaic panel 22 away from the first photovoltaic panel 21 is the light-receiving side.

[0059] This setup allows the second photovoltaic panel 22, when stacked, to generate electricity. When there is sunlight but insufficient visibility, it can simultaneously generate and store electricity and improve visibility.

[0060] Furthermore, such as Figure 4 and Figure 5 As shown, in the technical solution of Embodiment 3 of this application, a connector 221 is provided on the side of the second photovoltaic panel 22 that is away from the first photovoltaic panel 21, and a connecting structure 111 is provided at the corresponding position of the outer layer 11. The connector 221 and the connecting structure 111 have a connected state and a separated state.

[0061] The connector 221 and the connecting structure 111 are used to fix the second photovoltaic panel 22 after it is unfolded, so as to prevent the second photovoltaic panel 22 from shaking during the duty process and affecting the user's movements.

[0062] The connector 221 and the connection structure 111 can be connected using a snap-fit ​​method. Snap-fit ​​connections offer advantages such as easy disassembly, high stability, rapid assembly, non-destructive installation, and reusability, making them suitable for applications involving second photovoltaic panels 22 that are frequently opened and closed. Specific snap-fit ​​methods include clips, slots, tongues, sockets, protrusions, and edges.

[0063] The connector 221 and the connection structure 111 can also be connected by Velcro. Velcro has the advantages of being easy to operate, reusable, low cost, easy to adjust, and safe, and is suitable for the application of the second photovoltaic panel 22 that is opened and closed.

[0064] Example 4:

[0065] like Figure 6 As shown, Embodiment 4 is an improvement based on any one of Embodiments 1 to 3. Its main feature is the provision of a flexible connector 24 between the first photovoltaic panel 21 and the second photovoltaic panel 22. The flexible connector 24 is electrically connected to both the first photovoltaic panel 21 and the second photovoltaic panel 22. The flexible connector 24 allows for bending connections between the first photovoltaic panel 21 and the second photovoltaic panel 22, enabling stacking. This keeps the positions of the first photovoltaic panel 21 and the second photovoltaic panel 22 relatively fixed, preventing them from falling off. Furthermore, the electrical connection between the first photovoltaic panel 21 and the second photovoltaic panel 22 via the flexible connector 24 reduces wiring and facilitates installation.

[0066] Specifically, the flexible connector 24 can be made of silicone, rubber, TPU (thermoplastic polyurethane), EVA (ethylene vinyl acetate copolymer), TPE (thermoplastic elastomer), PVC (polyvinyl chloride), TPR (thermoplastic rubber), etc., which have good plasticity and can directly wrap the relatively fragile photovoltaic element, thus achieving a better connection effect. It should be noted that the main body of the flexible connector 24 is not conductive; the electrical connection is achieved through its internal flexible circuitry.

[0067] Example 5:

[0068] like Figure 7 As shown, Embodiment 5 is an improvement based on any one of Embodiments 1 to 3. It mainly involves providing a rotating connector 25 and a flexible line 26 between the first photovoltaic panel 21 and the second photovoltaic panel 22. The flexible line 26 is electrically connected to the first photovoltaic panel 21 and the second photovoltaic panel 22, respectively.

[0069] The rotating connector 25 provides a more stable connection between the first photovoltaic panel 21 and the second photovoltaic panel 22, resulting in a more stable structure. It also transforms the stacking and unfolding of the second photovoltaic panel 22 into a flipping mechanism, leading to better performance. Specifically, the rotating connector 25 can be a hinge, a rotating rod, or other similar structure; no specific limitations are specified here.

[0070] The flexible line 26 is specifically set on the side of the first photovoltaic panel 21 and the second photovoltaic panel 22 away from the outer layer 11, realizing electrical connection without affecting the internal wiring, and also facilitating inspection and maintenance.

[0071] The embodiments of this application have now been described in detail. To avoid obscuring the concept of this application, some details known in the art have not been described.

Those skilled in the art should understand that modifications can be made to the above embodiments or equivalent substitutions can be made to some technical features without departing from the scope and spirit of this application.
