Description

Technical Field

[0001] This utility model relates to a combined power supply Bluetooth tag, belonging to the field of Bluetooth tag technology. Background Technology

[0002] Currently, in today's Internet of Things (IoT) era, Bluetooth asset tags, as a wireless communication technology, are widely used in various asset tracking and management scenarios. A Bluetooth asset tag is an asset tracking and positioning device based on Bluetooth technology. By establishing a connection with a mobile phone or other Bluetooth communication devices, it can track and manage the location information of assets in real time. This type of tag typically consists of a miniaturized integrated circuit, a Bluetooth module, a battery, and an antenna.

[0003] Most existing Bluetooth tags use batteries as their power source. However, conventional button batteries or dry cell batteries require complex installation and connection structures, resulting in a large size and weight for Bluetooth tags, which limits their application scenarios. To solve this problem, flexible paper batteries are gradually being used in Bluetooth tags. For example, the patent application number 202420718839.8, "A Bluetooth Tag," uses a flexible power source to power the Bluetooth tag. This eliminates the need for the complex installation structure of conventional batteries, making the entire Bluetooth tag smaller, thinner, more flexible, and allowing for a wider range of applications.

[0004] However, like conventional batteries, flexible paper batteries, when used as a power source, still suffer from short battery life. Therefore, extending the battery life of Bluetooth tags powered by flexible paper batteries is an urgent problem to be solved. Utility Model Content

[0005] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a Bluetooth tag with combined power supply, which combines solar power generation and flexible paper battery power supply, and integrates the two into the Bluetooth tag, so that the Bluetooth tag has a longer battery life.

[0006] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:

[0007] A combined-powered Bluetooth tag includes a photovoltaic film, a flexible paper battery, and a flexible circuit board, wherein the photovoltaic film and the flexible paper battery are connected in parallel and then connected to the power input terminal of the flexible circuit board.

[0008] When the photovoltaic film is exposed to light, it supplies power to the flexible circuit board and simultaneously charges the flexible paper battery.

[0009] When the photovoltaic thin film is not exposed to light, the flexible paper battery powers the flexible circuit board.

[0010] Furthermore, the voltage output by the photovoltaic thin film is higher than that of the flexible paper battery.

[0011] Furthermore, the flexible circuit board is provided with a positive electrode connection block and a negative electrode connection block, both of which penetrate the flexible circuit board. The photovoltaic thin film and the flexible paper battery both supply power to the flexible circuit board through the positive electrode connection block and the negative electrode connection block.

[0012] Furthermore, the positive output terminal of the photovoltaic thin film is electrically connected to one side of the positive electrode connecting block, and the negative output terminal of the photovoltaic thin film is electrically connected to one side of the negative electrode connecting block.

[0013] Furthermore, the positive electrode of the flexible paper battery is electrically connected to the other side of the positive electrode connecting block, and the negative electrode of the flexible paper battery is electrically connected to the other side of the negative electrode connecting block.

[0014] Furthermore, it also includes a first substrate and a second substrate, with the second substrate attached to the first substrate, and the flexible paper battery, the photovoltaic film, and the flexible circuit board are all disposed within the sealed space formed by the first substrate and the second substrate.

[0015] Furthermore, the flexible paper battery, the photovoltaic film, and the flexible circuit board are all disposed on the first substrate, with the flexible paper battery and the photovoltaic film located on both sides of the flexible circuit board. The second substrate covers the flexible paper battery, the photovoltaic film, and the flexible circuit board and is bonded to the first substrate.

[0016] Furthermore, both the first substrate and the second substrate have light-transmitting windows for the photovoltaic thin film to receive light.

[0017] Furthermore, both the flexible paper battery and the flexible circuit board are disposed on the first substrate, the photovoltaic film is attached to the flexible paper battery with double-sided adhesive, and the second substrate covers the flexible paper battery, the photovoltaic film and the flexible circuit board and is attached to the first substrate.

[0018] Furthermore, a light-transmitting window is provided on the second substrate for the photovoltaic thin film to receive light.

[0019] By adopting the above technical solution, this utility model integrates a solar-powered thin film and a flexible paper battery onto a Bluetooth tag. When the solar-powered thin film is exposed to light, it supplies power to the flexible circuit board and simultaneously charges the flexible paper battery. When the solar-powered thin film is not exposed to light, the flexible paper battery supplies power to the flexible circuit board. By using the solar-powered thin film to assist in powering the flexible paper battery, the battery's lifespan is extended, thereby extending the Bluetooth tag's battery life. This utility model has a simple and practical structure, does not change the original structural framework of the Bluetooth tag, and has a wider range of applications. Attached Figure Description

[0026] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0027] Example 1

[0028] like Figure 1 As shown, this embodiment provides a combined power supply Bluetooth tag, which includes: a first substrate 4, a second substrate 5, a photovoltaic film 1, a flexible paper battery 2, and a flexible circuit board 3. The first substrate 4 and the second substrate 5 are bonded together, and the photovoltaic film 1, the flexible paper battery 2, and the flexible circuit board 3 are all installed within the sealed space formed by the first substrate 4 and the second substrate 5. A Bluetooth control circuit is provided on the flexible circuit board 3 to realize the relevant functions of the Bluetooth tag.

[0029] This system includes a photovoltaic (PV) film 1, a flexible paper battery 2, and a flexible circuit board 3. The PV film 1 and the flexible paper battery 2 are connected in parallel and then connected to the power input terminal of the flexible circuit board 3. When the PV film 1 is exposed to sunlight, it supplies power to the flexible circuit board 3 and simultaneously charges the flexible paper battery 2. When the PV film 1 is not exposed to sunlight, the flexible paper battery 2 supplies power to the flexible circuit board 3. In this embodiment, the output voltage of the PV film 1 is 1.6V, and the voltage of the flexible paper battery 2 is 1.5V. When the PV film 1 receives sunlight, such as during periods of ample sunlight during the day, it generates electricity, which can both supply power to the flexible circuit board 3 and charge the flexible paper battery 2. When the PV film 1 is not exposed to sunlight, such as during periods of no sunlight at night, the flexible paper battery 2 supplies power to the flexible circuit board 3. Since the PV film 1 does not have an energy storage function, the energy consumption of the flexible paper battery 2 on the PV film 1 is negligible. The flexible paper battery 2 is powered by a photovoltaic thin film 1, thereby extending the battery life of the flexible paper battery 2.

[0030] like Figure 1 , 2 As shown, the flexible circuit board 3 of this embodiment is provided with a positive electrode connection block 31 and a negative electrode connection block 32. Both the positive electrode connection block 31 and the negative electrode connection block 32 penetrate the flexible circuit board 3. The photovoltaic thin film 1 and the flexible paper battery 2 both supply power to the flexible circuit board 3 through the positive electrode connection block 31 and the negative electrode connection block 32. Figure 2 As shown, in this embodiment, the positive output terminal of the photovoltaic thin film 1 is electrically connected to one side of the positive electrode connection block 31, and the negative output terminal of the photovoltaic thin film 1 is electrically connected to one side of the negative electrode connection block 32. Figure 2 As shown, in this embodiment, the positive electrode of the flexible paper battery 2 is electrically connected to the other side of the positive electrode connecting block 31, and the negative electrode of the flexible paper battery 2 is electrically connected to the other side of the negative electrode connecting block 32. This embodiment staggers the connection points of the photovoltaic thin film 1 and the flexible paper battery 2 to the flexible circuit board 3, resulting in a simpler and more reasonable structure. The positive and negative output terminals of the photovoltaic thin film 1 are located on one side of the flexible circuit board 3, while the positive and negative electrodes of the flexible paper battery 2 are located on the other side. Since the positive electrode connecting block 31 and the negative electrode connecting block 32 penetrate the flexible circuit board 3, the positive and negative output terminals of the photovoltaic thin film 1 are connected to one side of the positive electrode connecting block 31 and the negative electrode connecting block 32, and the positive and negative electrodes of the flexible paper battery 2 are connected to the other side of the positive electrode connecting block 31 and the negative electrode connecting block 32.

[0031] like Figure 1 , 2As shown in Figures 1 and 3, in this embodiment, the flexible paper battery 2, the photovoltaic film 1, and the flexible circuit board 3 are all attached to the first substrate 4. The flexible paper battery 2 and the photovoltaic film 1 are located on the left and right sides of the flexible circuit board 3. The second substrate 5 covers the flexible paper battery 2, the photovoltaic film 1, and the flexible circuit board 3 and is attached to the first substrate 4.

[0032] like Figure 3 As shown, in this embodiment, both the first substrate 4 and the second substrate 5 are provided with light-transmitting windows 6 for the photovoltaic thin film 1 to receive light. Figure 3 The diagram only shows a schematic of the light-transmitting window 6 on the second substrate 5. The structure of the light-transmitting window 6 on the first substrate 4 is the same as that on the second substrate 5.

[0033] like Figure 1 As shown, in this embodiment, the side of the first substrate 4 that is opposite to the second substrate 5 is provided with strong adhesive 7 and release paper 8. After tearing off the release paper 8, the Bluetooth tag can be pasted on the item.

[0034] Example 2

[0035] like Figure 4 , 5 As shown, this embodiment provides another mounting structure for the flexible paper battery 2 and the photovoltaic thin film 1. The flexible paper battery 2 and the flexible circuit board 3 are both attached to the first substrate 4. The photovoltaic thin film 1 is attached to the flexible paper battery 2 with double-sided adhesive tape 9. The second substrate 5 covers the flexible paper battery 2, the photovoltaic thin film 1 and the flexible circuit board 3 and is attached to the first substrate 4.

[0036] like Figure 6 As shown, the second substrate 5 of this embodiment has a light-transmitting window 6 for the photovoltaic thin film 1 to receive light.

[0037] The specific embodiments described above further illustrate the technical problems, technical solutions, and beneficial effects of this utility model. It should be understood that the above descriptions are merely specific embodiments of this utility model and are not intended to limit this utility model.
