Description

Technical Field

[0001] This utility model relates to the field of mobile power supplies, and in particular to a smart charging mobile power supply. Background Technology

[0002] A portable power bank is a device that stores electrical energy. It consists of a casing, a battery, a circuit board, a charging device, and a power chip, and is used to supply power to devices.

[0003] Handheld terminal devices, such as mobile phones, are powered by batteries. During use, it is necessary to avoid overcharging and over-discharging the battery to prevent affecting its lifespan.

[0004] Existing power banks charge the batteries of handheld devices manually, and the charging amount cannot be controlled by the power control software on the handheld device. If the user does not disconnect the circuit in time, it will cause the battery to be overcharged, which will affect the battery's lifespan. To address this, we propose an intelligent charging power bank. Utility Model Content

[0005] The technical problem to be solved by this utility model is to provide an intelligent charging mobile power supply, whose charging amount can be automatically controlled by the power control software on the handheld terminal device, thereby avoiding overcharging of the handheld terminal device battery and ensuring the battery life.

[0006] Technical solution: This utility model provides a smart charging power bank, including a power bank body, the power bank body comprising:

[0007] A housing, wherein a storage battery is disposed inside the housing;

[0008] A circuit board, which is electrically connected to a battery, has a Bluetooth chip and a power chip connected to it, and the power chip and the Bluetooth chip are electrically connected. The Bluetooth chip is used to connect to a handheld terminal device via Bluetooth.

[0009] A charging device, which is fixed to the housing and electrically connected to the power chip.

[0010] Furthermore, the charging device has a Type-C interface.

[0011] Furthermore, the charging device is a wireless charging module.

[0012] Furthermore, the housing has a groove for matching the handheld terminal device, and an elastic pressing mechanism is provided in the groove.

[0013] Furthermore, the elastic clamping mechanism includes a groove formed in the inner wall of the groove, an elastic element fixed in the groove, a rod fixed to the free end of the elastic element, and one end of the rod located outside the groove and connected to a pressure plate.

[0014] Furthermore, at least two sets of the elastic clamping mechanism are provided, and the elastic clamping mechanism is offset from the charging port of the handheld terminal device.

[0015] Furthermore, the elastic element is a spring.

[0016] Beneficial effects:

[0017] 1. The Bluetooth chip of this utility model can connect with the Bluetooth chip of a handheld terminal device, thereby enabling the power supply to automatically monitor the real-time power level of the handheld terminal device. When the power level is lower than a set value, the Bluetooth chip triggers an electrical signal to connect the charging terminal of the power chip. At this time, the power supply will charge the mobile phone or other handheld terminal device until the set value is reached. Then, the charging terminal of the power chip disconnects and charging stops. The charging amount of this power supply can be automatically controlled by the power control software on the handheld terminal device, thereby avoiding overcharging of the handheld terminal device battery and ensuring the battery life.

[0018] 2. The charging device of this utility model is a Type-C interface or a wireless charging module. The Type-C interface and the wireless charging module can be installed together on the housing, so users can choose the Type-C interface or the wireless charging module for charging according to their needs.

[0019] 3. The elastic clamping mechanism of this utility model can fix the handheld terminal device in the groove, so that the user does not need to continuously use his hands to combine the two, thereby freeing up the user's hands and improving the convenience of use. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0027] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] like Figure 2As shown, a smart charging power bank includes a power body 1, which consists of a housing 101, a circuit board 104, and a charging device 2. A battery 102 is fixed inside the housing 101. The circuit board 104 is electrically connected to the battery 102. A Bluetooth chip 105 and a power chip 107 are also connected to the circuit board 104, and the power chip 107 and the Bluetooth chip 105 are electrically connected. The Bluetooth chip 105 is used to connect to a handheld terminal device via Bluetooth. The charging device 2 is fixed to the housing 101 and is electrically connected to the power chip 107. When the charging device 2 is connected to the handheld terminal device, the battery 102 can charge the handheld terminal device.

[0030] The charging device 2 is a Type-C interface 202 or a wireless charging module 201. The Type-C interface 202 and the wireless charging module 201 can be mounted together on the housing 101, so the user can choose to charge using either the Type-C interface 202 or the wireless charging module 201 as needed.

[0031] like Figure 1 As shown, the handheld terminal device in this embodiment has Bluetooth functionality, such as a mobile phone, tablet, or other product. It should have power control software installed, such as the Micro Phoenix APP. During use, when the mobile phone's Bluetooth chip is connected to the Bluetooth chip 105 of this power supply, the power supply automatically monitors the real-time power level of the mobile phone or other handheld terminal device under the action of the Bluetooth chip 105 (this is prior art and will not be elaborated here). When the power level is lower than the set value, the Bluetooth chip 105 triggers an electrical signal to connect the charging terminal of the power chip 107. At this time, the power supply will charge the mobile phone or other handheld terminal device until the set value is reached, at which point the charging terminal of the power chip 107 is disconnected and charging stops.

[0032] Furthermore, the power supply can be set to charge the phone to a specific level via the Micro Phoenix APP or other power control software. For example, the charging level can be set to a range of 20%-80%, or any level, such as N%-99%. When the phone's battery level drops below the set value, the power supply will start charging the phone or other handheld terminal device, effectively protecting the phone's battery. In particular, the battery itself can be damaged or have its lifespan reduced if it is deeply discharged a certain number of times, thus improving the battery's lifespan.

[0033] Example 2:

[0034] This embodiment is a further improvement on embodiment 1. The main improvement is that in embodiment 1, the handheld terminal device and the power source are separate and cannot be mechanically combined. The user needs to continuously use their hands to combine the two, especially when using a wireless charging template, where ensuring the stability of the combined device is crucial. Therefore, it does not free the user's hands, resulting in poor convenience. In this embodiment, the above defects can be avoided. Specifically:

[0035] like Figure 2-3 As shown, the housing 101 has a groove 4 for matching the handheld terminal device. An elastic clamping mechanism 3 is provided in the groove 4. The distance between the elastic clamping mechanism 3 and the other side of the groove 4 is less than the length of the handheld terminal device. Therefore, when the handheld terminal device, such as a mobile phone, is placed in the groove 4, the mobile phone will exert a force on the elastic clamping mechanism 3, causing it to shift. This causes the elastic clamping mechanism 3 to exert a reaction force on the mobile phone, thereby clamping the mobile phone in the groove 4. The wireless charging module 201 is located at the bottom of the groove 4 and can charge the mobile phone.

[0036] like Figure 4 As shown, the elastic clamping mechanism 3 includes a groove 304 formed in the inner wall of the groove 4. An elastic element 303 is provided in the groove 304. The elastic element 303 is a spring. One end of the spring is fixed to the inner side of the groove 304, and the other end is fixed to a rod 301. One end of the rod 301 is located outside the groove 304 and is connected to a pressure plate 302. When the pressure plate 302 is subjected to force, the rod 301 will compress the elastic element 303, thereby causing the pressure plate 302 to move. This allows the mobile phone or other handheld terminal device to be completely located in the groove 4. Since the elastic element 303 will generate a reaction force after being compressed, the pressure plate 302 will apply a force to the mobile phone, thereby clamping and fixing the mobile phone in the groove 4.

[0037] like Figure 3 As shown, the elastic pressing mechanism 3 is provided with at least two sets, which press against two points of the mobile phone or other handheld terminal device. Furthermore, the elastic pressing mechanism 3 is offset from the charging port of the handheld terminal device to avoid the inability to use the Type-C data cable for charging due to the charging port being blocked.

[0038] Apart from the above, this embodiment is exactly the same as Embodiment 1, and will not be described again here.

[0039] Working principle: First, the Bluetooth chip 105 is connected to the Bluetooth chip of the handheld terminal device. Under the action of the Bluetooth chip 105, the power supply automatically monitors the real-time battery level of the mobile phone or other handheld terminal device. The power control software on the handheld terminal device, such as the Micro Phoenix APP, sets the charging level that the power supply needs to charge the mobile phone. The charging level range is set to N%-99%. When the mobile phone battery level is lower than the set value and the mobile phone is connected to the charging device 2 of the power supply, the power supply starts charging the mobile phone or other handheld terminal device, effectively protecting the mobile phone battery. When the mobile phone battery level reaches the set value, the Bluetooth chip 105 triggers an electrical signal, thereby disconnecting the charging terminal of the power chip 107 and ending the charging operation to avoid overcharging. In addition, the power supply uses the elastic clamping mechanism 3 to fix the mobile phone in the groove 4, so that the user does not need to continuously combine the two by hand, freeing up the user's hands and improving the convenience of use.

[0040] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent transformations or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
