Description

Technical Field

[0001] This utility model relates to the field of portable power banks, and more particularly to a stand-type portable power bank. Background Technology

[0002] A power bank is typically a portable, rechargeable energy storage device used to charge electronic devices while traveling or when there is no fixed power source. For convenient and comfortable use, a stand-type power bank is needed.

[0003] In the process of developing this application, the inventors discovered the following problems with the prior art: Existing stand-type power banks usually use magnetic blocks to fix the position of the mobile phone and charge the mobile phone through wireless charging technology. However, when the mobile phone is charged in the storage state, this fixing method may be affected by external forces (such as the bumps when walking or riding in a car or the backpack being hit), which may cause the connection between the mobile phone and the power bank to be unstable or even disconnected, resulting in the termination of wireless charging or the power interface of the charging cable falling off, making it impossible to continue charging the mobile phone.

[0004] Therefore, those skilled in the art have provided a stand-type portable power bank to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a stand-type mobile power bank that fixes the position of the phone when stored, reducing the impact of external factors on the stability of the phone during charging.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A stand-type portable power bank includes a housing with a hollow interior containing a battery and a circuit board. Connecting blocks are fixedly connected to both sides of the housing near the bottom. Each connecting block has a circular channel through which a support frame is rotatably mounted. The two support frames are L-shaped, with their bottoms tilted backwards, and have triangular plate-like supports near the bottom inside. A pivot is located on the side of each support frame near the housing, and the pivot is rotatably mounted within the circular channel of the connecting block. A snap-fit ​​block is fixedly connected to the bottom of each support frame near the pivot. Each connecting block has a snap-fit ​​interface near the snap-fit ​​block, and the snap-fit ​​block and the snap-fit ​​interface are mutually engaged.

[0008] Furthermore, the outer casing has a circular hole near the front side, and a magnetic block is fixedly connected inside the circular hole. The outer casing has three grooves near the bottom of the rear side, and each of the three grooves is equipped with a charging cable. One end of the three charging cables is a charging plug, and the models of the charging plugs are different. The other end is fixedly connected to the outer casing.

[0009] Furthermore, a charging port is fixedly connected to one side of the outer casing. The charging port is a Type-C port, which can be used to plug in a Type-C fast charging plug for charging.

[0010] Furthermore, a second charging port is fixedly connected to the lower end of the outer casing near the first charging port. The second charging port is a Type-A connector that can be inserted into a Type-A connector.

[0011] Furthermore, a circular hole is provided near the lower end of the second charging port on the outer casing, and a power switch is movably installed in the circular hole. The rear end of the power switch is connected to the circuit board inside the outer casing.

[0012] This utility model has the following beneficial effects:

[0013] 1. The present invention proposes a stand-type mobile power bank. When the support frame is unfolded, the mobile power bank is supported vertically by the inclination of the bottom of the two support frames when placed upright, and horizontally by the two ends of the L-shaped of a single support frame when placed horizontally. The mobile phone is fixed by magnetic blocks when supported vertically or horizontally.

[0014] 2. The present invention proposes a stand-type mobile power bank. When the support frame is stored, the bottom locking block fits into the card interface to fix the position of the support frame.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Reference Figure 2 , Figure 3 One embodiment provided by this utility model:

[0023] A stand-type mobile power bank includes a shell 1, which is hollow inside and has a battery, circuit board, and transmitting coil fixedly connected inside. Connecting blocks 4 are fixedly connected to both sides of the shell 1 near the bottom. Each connecting block 4 has a circular channel through which a support frame 2 is rotatably mounted. The two support frames 2 are L-shaped with their bottoms tilted backwards, and have triangular plate-shaped supports near the bottom inside. A pivot is provided on the side of the support frame 2 near the shell 1, and the pivot is rotatably mounted in the circular channel of the connecting block 4. A snap-fit ​​block 10 is fixedly connected to the bottom of the support frame 2 near the pivot. Each of the two connecting blocks 4 has a snap-fit ​​interface 9 near the snap-fit ​​block 10, and the snap-fit ​​block 10 and the snap-fit ​​interface 9 are mutually fitted.

[0024] Specifically, the outer shell 1 is a rectangular block with rounded corners on all four sides and a hollow interior. Inside the outer shell 1, a battery, a circuit board, and a transmitting coil are fixedly connected (the battery stores power, the circuit board converts power and controls power flow, and the transmitting coil uses wireless charging technology, all of which are existing technologies and will not be described in detail). Connecting blocks 4 are fixedly connected to both sides near the bottom of the outer shell 1. Circular channels are provided near the rear of the two connecting blocks 4. The rotating shaft of the support frame 2 is rotatably installed in the circular channels, and a card interface 9 is provided near the rotating shaft. The support frame 2 is an L-shaped block with triangular plate-shaped supports near the bottom of the L-shaped corners. A card block 10 is fixedly connected to the bottom near the rotating shaft. The length of the rotating shaft of the support frame 2 is higher than the height of the connecting blocks 4. When the support frame 2 is pulled down, the card block 10 and the card interface 9 are released from contact, thus releasing the fixed position between the support frame 2 and the connecting blocks 4.

[0025] Reference Figure 1 , Figure 4The outer casing 1 has a circular hole near the front, and a magnetic block 3 is fixedly connected inside the circular hole. The outer casing 1 has three grooves near the bottom of the rear side, and each of the three grooves has a charging cable 8. One end of the three charging cables 8 is a charging plug, and the charging plugs are of different models. The other end is fixedly connected to the outer casing 1. A first charging port 5 is fixedly connected to one side of the outer casing 1. The first charging port 5 is a Type-C port, which can be used to charge a Type-C fast charging plug. A second charging port 6 is fixedly connected to the lower end of the outer casing 1 near the first charging port 5. The second charging port 6 is a Type-A port, which can be used to insert a Type-A plug. The outer casing 1 has a circular hole near the lower end of the second charging port 6. A power switch 7 is movably installed in the circular hole. The rear end of the power switch 7 is connected to the circuit board inside the outer casing 1.

[0026] Specifically, the outer casing 1 has a circular hole near the front, and a magnetic block 3 is fixedly connected inside the circular hole. A transmitting coil is fixedly connected inside the outer casing 1 near the magnetic block 3 (the magnetic block 3 ensures perfect alignment between the receiving coil inside the phone and the transmitting coil inside the outer casing 1; this precise alignment greatly improves energy transmission efficiency; this is existing technology and will not be elaborated further). The outer casing 1 has three grooves near the rear, each containing a charging cable 8. One end of each charging cable 8 has a different type of charging plug, and the other end is fixedly connected to the outer casing 1. When the phone needs wired charging, the corresponding charging cable 8 is taken out according to the phone's charging port type and connected for charging. A charging port is fixedly connected to one side of the outer casing 1. 5. Charging port 5 is a Type-C port, which can be used to charge Type-C fast charging plugs. A second charging port 6 is fixedly connected to the lower end of the outer casing 1 near the first charging port 5. The second charging port 6 is a Type-A port, which can be used to charge Type-A plugs. When multiple devices need to be charged, the Type-A plug of the external power cord can be inserted to power the devices. A circular hole is provided at the lower end of the outer casing 1 near the second charging port 6. A power switch 7 is movably installed in the circular hole. The rear end of the power switch 7 is connected to the circuit board inside the outer casing 1. By pressing the power switch 7, a command is sent to the circuit board inside the outer casing 1 to control the release or disconnection of the power in the battery.

[0027] Working principle: For vertical support, pull down the two support frames 2 to release the contact between the latch block 10 and the latch interface 9, thereby releasing the limit between the two support frames 2 and the two connecting blocks 4. Rotate the support frame 2 to 180° to make the two support frames 2 parallel to each other. Then tilt it backward so that the inclined surface at the bottom of the two support frames 2 is in contact with the placement plane to achieve vertical support. Attach the back of the mobile phone to the surface of the magnetic block 3. The magnetic force of the magnetic block 3 supports the mobile phone. For horizontal support, place the power bank horizontally and rotate the support frame 2 to the limit. The L-shaped ends of the support frame 2 contact the plane to achieve support. Attach the back of the mobile phone to the surface of the magnetic block 3. After completing vertical or horizontal support, press the power switch 7 to turn on the power supply. Wirelessly charge the mobile phone through the transmitting coil. For mobile phones without wireless charging function, you can also take out the charging cable 8 corresponding to the model on the back of the casing 1 and charge it through the mobile phone charging port. For special models of devices, you can also connect an external charger through the second charging port 6 via the Type-A interface.

[0028] Secondly, when storing the phone, there is no need to remove it. Simply rotate the two support brackets 2 back to their original positions and push them upwards to make the card connector 10 fit with the card interface 9, thus fixing the positions of the support brackets 2 and the connecting block 4. The two support brackets 2, together with the magnetic block 3, limit the position of the phone, reducing the impact of external factors on its charging process after storage. In this way, the position of the phone is fixed when storing, reducing the impact of external factors on the stability of the phone when charging after storage.

[0029] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
