Description

Technical Field

[0001] This utility model relates to the field of mobile power supply technology, and in particular to a mobile power supply with power failure protection function. Background Technology

[0002] Portable power banks, as portable chargers that can charge various digital devices anytime, anywhere, have become an indispensable electronic product in people's daily lives. With the continuous advancement of electronic technology, the development of new electronic components and chips has provided technical support for the functional innovation of power banks. Intelligent control chips are gradually being applied in the field of power banks. These chips possess powerful data processing and logic judgment capabilities, enabling them to monitor key parameters such as charging and discharging current, voltage, and temperature of the power bank in real time. When abnormal parameters are detected, the chip can quickly issue a command to control the circuit to cut off the current path, achieving power outage protection. In practical usage scenarios, when power banks charge external devices such as mobile phones, tablets, and headphones, it is usually necessary to connect the external interface of the power bank to the charging port of the external device using a charging cable. This process relies on a stable connection of the charging cable to achieve power transfer. Furthermore, "using the device while charging" has become an extremely common scenario when users use power banks to charge their devices—for example, watching videos while charging during commutes, replying to messages while charging during office breaks, and navigating while charging outdoors.

[0003] Regarding the aforementioned and existing related technologies, the inventors believe that the following defects often exist: the external interface of the power bank and the charging cable connector are mostly simple plug-and-play connections. When the user operates the device, the device will pull and shake the charging cable, which can easily cause the connector and external interface to loosen, resulting in charging interruption and reduced charging efficiency. At the same time, when the user unplugs the connection cable after charging is complete, the external charging interface of the existing power bank is mostly in a completely exposed state. Dust, lint, small particles and other foreign objects can easily enter the interface. Long-term accumulation can lead to poor interface contact and even short circuit failure. In addition, existing power banks generally lack a structure for storing the charging cable. Utility Model Content

[0004] The technical problem this invention aims to solve is that existing power banks use a simple plug-and-play connection between the external interface and the charging cable. When operating a handheld device, the device pulls and shakes the charging cable, which can easily cause the connector to loosen, resulting in charging interruption and reduced efficiency. After charging is complete and the cable is unplugged, the external charging interface is often completely exposed, making it easy for dust, lint, and other foreign objects to enter. Long-term accumulation can lead to poor contact or even short circuits. Furthermore, existing power banks generally lack a charging cable storage structure. Therefore, we propose a power bank with a power-off protection function.

[0005] To achieve the above objectives, this application adopts the following technical solution: a portable power bank with power failure protection function, comprising a portable power bank body, a charging port on the surface of the portable power bank body, two external interfaces on the surface of the portable power bank body, each of the two external interfaces being electrically connected to a connector, a connecting wire installed on the side of the connector away from the portable power bank body, a control switch installed on the upper surface of the portable power bank body, a limit plate fixedly connected to the surface of the portable power bank body, a mounting bracket fixedly connected to the surface of the portable power bank body, a plurality of springs fixedly connected to the inner wall of the mounting bracket, a clamping plate fixedly connected to one end of the plurality of springs, the clamping plate being slidably connected to the inner wall of the mounting bracket, and the inner wall of the clamping plate abutting against the connector.

[0006] Preferably, an arc-shaped soft pad is fixedly connected to the inner wall of the clamping plate. The arc-shaped soft pad is made of silicone rubber, and the inner wall of the arc-shaped soft pad abuts against the connector.

[0007] Preferably, a sliding hole is provided on one side of the mounting bracket, and a round rod is slidably connected to the inner wall of the sliding hole. One end of the round rod is fixedly connected to the clamping plate, and the other end of the round rod is fixedly connected to a round block.

[0008] Preferably, the power bank body has a placement groove on the side away from the connector, an arc-shaped plate is slidably connected to the inner wall of the placement groove, a fixing block is fixedly connected to the side of the arc-shaped plate away from the connector, sliding grooves are formed on both sides of the inner wall of the placement groove, two threaded rods are threadedly inserted into the power bank body, the threaded rods pass through the sliding grooves, a locking block is rotatably connected to one end of the threaded rod, a locking groove is formed on both sides of the arc-shaped plate, the locking block is slidably connected to the inner wall of the locking groove, and a rotating shaft is fixedly connected to the other end of the threaded rod.

[0009] Preferably, the upper and lower surfaces of the inner wall of the placement groove are provided with positioning grooves, and a positioning rod is fixedly connected to the side of the arc plate away from the connector, the size of the positioning rod being adapted to the size of the positioning groove.

[0010] Preferably, the inner wall of the slide groove has two limiting grooves, and the inner walls of the two limiting grooves are slidably connected to a sliding plate. One side of the sliding plate is fixedly connected to a locking block, and the arc surface of the rotating shaft has several square grooves.

[0011] The technical effects and advantages of this utility model are as follows:

[0012] In this invention, by setting up a mounting bracket, spring, and clamping plate, when the power bank is in use, the elastic force of the spring allows the clamping plate to effectively clamp and limit the connector inserted into the external interface, increasing the tightness of the connection between the connector and the external interface, greatly reducing circuit failures caused by loose connections, and ensuring stable power supply. When the external connector is unplugged after charging is complete, the spring force pushes the clamping plate forward until it is in contact with the limiting plate. At this time, the clamping plate can block the external interface, preventing dust, foreign objects, etc. from entering the internal part of the external interface, thus providing protection. From the aspects of connection stability and interface protection, the reliability and safety of the power bank are improved.

[0013] In this invention, a placement groove is provided on the side of the power bank body away from the connector. At the same time, the sliding adjustment and fixation of the arc plate are achieved by the cooperation of the sliding groove, threaded rod, and locking block and slot. This structure can provide dedicated storage space for the connector and connecting cable. Users can properly place the connector and connecting cable in the placement groove to avoid them being scattered randomly or mixed with other items. Attached Figure Description

[0021] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0022] Reference Figures 1-5As shown, this utility model provides a technical solution: a portable power bank with power failure protection function, including a portable power bank body 1, a charging port 2 on the surface of the portable power bank body 1, two external interfaces 3 on the surface of the portable power bank body 1, each of the two external interfaces 3 being electrically connected to a connector 4, a connecting wire 5 installed on the side of the connector 4 away from the portable power bank body 1, a control switch 6 installed on the upper surface of the portable power bank body 1, a limit plate 8 fixedly connected to the surface of the portable power bank body 1, a mounting bracket 7 fixedly connected to the surface of the portable power bank body 1, a plurality of springs fixedly connected to the inner wall of the mounting bracket 7, a clamping plate 9 fixedly connected to one end of the plurality of springs, the clamping plate 9 being slidably connected to the inner wall of the mounting bracket 7, and the inner wall of the clamping plate 9 abutting against the connector 4. By setting up the mounting bracket 7, spring and clamp 9, when the power bank body 1 is in use, the clamp 9 can effectively clamp and limit the connector 4 inserted into the external interface 3 by utilizing the elastic force of the spring, increasing the tightness of the connection between the connector 4 and the external interface 3, greatly reducing the circuit failure caused by loose connection, and ensuring the stability of the power supply process; when the external connector 4 is pulled out after charging is completed, the elastic force of the spring will push the clamp 9 forward until the clamp 9 is in contact with the limiting plate 8. At this time, the clamp 9 can block the external interface 3 to prevent dust, foreign objects and other objects from entering the interior of the external interface 3, thus playing a protective role. From the aspects of connection stability and interface protection, the reliability and safety of the power bank body 1 are improved. The inner wall of the clamp 9 is fixedly connected with an arc-shaped soft pad 10, which is made of silicone rubber, and the inner wall of the arc-shaped soft pad 10 abuts against the connector 4. When the curved soft pad 10 abuts against the connector 4, the elasticity of the silicone rubber can enhance the stability of the clamping and reduce the loosening of the connector 4. At the same time, its softness can prevent the clamping plate 9 from causing hard wear to the connector 4, protect the connector 4, and extend the service life of the power supply and external equipment. A sliding hole 11 is provided on one side of the mounting bracket 7. A round rod 12 is slidably connected to the inner wall of the sliding hole 11. One end of the round rod 12 is fixedly connected to the clamping plate 9, and the other end of the round rod 12 is fixedly connected to a round block 13. By providing a sliding hole 11 on one side of the mounting bracket 7, the round rod 12 fixed to the clamping plate 9 slides along the sliding hole 11, providing guidance for the sliding of the clamping plate 9. At the same time, it is also convenient for the user to pull the round block 13 to move the clamping plate 9 backward, thereby facilitating the insertion of the connector 4. A placement groove 14 is provided on the side of the power supply body 1 away from the connector 4. An arc-shaped plate 15 is slidably connected to the inner wall of the placement groove 14. A fixing block 16 is fixedly connected to the side of the arc-shaped plate 15 away from the connector 4. Sliding grooves 17 are provided on both sides of the inner wall of the placement groove 14. Two threaded rods 18 are threadedly inserted into the power supply body 1. The threaded rods 18 pass through the sliding grooves 17. A locking block 20 is rotatably connected to one end of the threaded rod 18. A locking groove 26 is provided on both sides of the arc-shaped plate 15. The locking block 20 is slidably connected to the inner wall of the locking groove 26. A rotating shaft 19 is fixedly connected to the other end of the threaded rod 18.A placement slot 14 is provided on the side of the power bank body 1 away from the connector 4. With the cooperation of the sliding groove 17, the threaded rod 18, the locking block 20 and the locking slot 26, the arc plate 15 can be slidably adjusted and fixed. This structure can provide dedicated storage space for the connector 4 and the connecting cable 5. Users can properly place the connector 4 and the connecting cable 5 in the placement slot 14 to avoid them being scattered or mixed with other items. The upper and lower surfaces of the inner wall of the placement slot 14 are provided with positioning slots 24. A positioning rod 25 is fixedly connected to the side of the arc plate 15 away from the connector 4. The size of the positioning rod 25 is adapted to the size of the positioning slot 24. When the curved plate 15 is slid along the placement groove 14, the positioning rod 25 on the curved plate 15 engages with the positioning groove 24, allowing the locking block 20 to be quickly and precisely aligned with the locking slot 26. This engagement allows for quick determination of the fixed position of the curved plate 15, reducing adjustment time and difficulty, and improving the ease of use of the storage structure. The inner wall of the slide groove 17 has two limiting grooves 21, and the inner walls of the two limiting grooves 21 are slidably connected to a sliding plate 22. One side of the sliding plate 22 is fixedly connected to the locking block 20. The arc surface of the rotating shaft 19 has several square grooves 23. The sliding plate 22 along the limiting grooves 21 provides guidance and limitation for the movement of the locking block 20, preventing the locking block 20 from shifting during adjustment and ensuring that the locking block 20 is accurately engaged in the locking slot 26. The square grooves 23 on the rotating shaft 19 increase the friction for the user's hand grip, allowing the user to adjust the threaded rod 18 with less effort.

[0023] Working principle: The power bank body 1 obtains and stores electrical energy through the charging port 2. When in use, it supplies power to external devices through the external interface 3, connector 4 and connecting cable 5. The control switch 6 is responsible for starting and stopping the entire system.

[0024] Regarding connection fixation and interface protection, the user first needs to pull the round block 13 outside the sliding hole 11 on one side of the mounting bracket 7. The round block 13 drives the round rod 12 fixed thereto to slide along the sliding hole 11, thereby pulling the clamping plate 9 to move away from the external interface 3. At this time, the spring is compressed and stores elastic potential energy. After the connector 4 is inserted into the external interface 3 and the electrical connection is completed, the round block 13 is released, the spring releases elastic potential energy, and pushes the clamping plate 9 to slide along the inner wall of the mounting bracket 7 until the inner wall of the clamping plate 9 and the connector 4 are tightly abutted. At this time, the silicone rubber arc-shaped soft pad 10 on the inner wall of the clamping plate 9 will adhere to the surface of the connector 4 to form a flexible clamp due to the elastic properties of silicone rubber. The elastic force increases the tightness of the fit between the connector 4 and the external interface 3, preventing the connector 4 from loosening due to equipment pulling and shaking, and also preventing the clamping plate 9 from hard contacting the connector 4 and causing wear, ensuring stable current transmission and reducing charging interruptions and circuit failures caused by poor contact. During this process, the round rod 12 slides along the sliding hole 11, providing precise guidance for the movement of the clamping plate 9, ensuring that the clamping plate 9 only moves in the direction of approaching / moving away from the external interface 3, avoiding deviation that could lead to clamping failure. When charging is complete and the user pulls out the connector 4, the clamping plate 9 is no longer blocked by the connector 4, and the elastic potential energy of the spring is further released, pushing the clamping plate 9 to continue sliding towards the limiting plate 8 until the edge of the clamping plate 9 is completely in contact with the limiting plate 8 on the surface of the power bank body 1; at this time, the clamping plate 9 just covers the outside of the external interface 3, forming a physical barrier to prevent dust, lint, small particles and other foreign objects from entering the interior of the external interface 3, avoiding long-term accumulation that could lead to poor interface contact or short circuit failure, and extending the service life of the external interface 3.

[0025] In terms of storage function, when it is necessary to store the connector 4 and the connecting cable 5, the user first rotates the rotating shaft 19 on both sides of the power bank body 1 (the square groove 23 on the arc surface of the rotating shaft 19 can increase the grip friction of the hand and make it easier to exert force). The rotating shaft 19 drives the threaded rod 18 fixed thereto to rotate. During the rotation, the threaded rod 18 will drive the locking block 20 connected at one end to disengage from the locking groove 26. During this process, the sliding plate 22 fixed to the locking block 20 will slide synchronously along the limiting groove 21 on the inner wall of the sliding groove 17. The limiting groove 21 provides guidance for the sliding plate 22 and the locking block 20 to prevent the locking block 20 from shifting. Once the locking block 20 is completely disengaged from the slots 26 on both sides of the arc plate 15, the arc plate 15 is released from its fixation. Pulling the fixing block 16 causes the arc plate 15 to extend out of the placement slot 14. At this time, the user can neatly place the connector 4 and the connecting wire 5 into the placement slot 14. After placement, the arc plate 15 can be pushed to slide on the inner wall of the placement slot 14. When the positioning rod 25 is in contact with the positioning slot 24, the rotating shaft 19 is rotated in the opposite direction, causing the threaded rod 18 and the locking block 20 to move in the opposite direction, so that the locking block 20 is accurately locked into the slot 26 of the arc plate 15, thus completing the fixation of the arc plate 15. The arc plate 15 forms a seal on the placement slot 14, preventing the connector 4 and the connecting wire 5 from scattering or getting tangled with other items, thus achieving convenient storage.

[0026] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
